Pemphigus vulgaris of the oral cavity in a patient with coeliac disease: coincidence or relationship?

A combined treatment regimen for desquamative gingivitis in patients with oral lichen planus

Background:  Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). Methods:  A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. Results:  PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be re…

Saliva: Its value as a biological matrix and current methods of sampling

Saliva is a non-invasive medium, its analysis is useful to measure a wide range of hormones, drugs, narcotics, antibodies, host, microbial, fungal and viral DNA up to salivary mRNA; hence, it has been suggested to be an easy and reliable biomarker in disease diagnostics, such as inflammatory mouth infections/diseases, and in normal health surveillance. In light of this potential, our primary endpoint is to review the current knowledge on saliva analyses and its recent methods of sampling.

A pragmatic window of opportunity to minimise the risk of MRONJ development in individuals with osteoporosis on Denosumab therapy: a hypothesis

Abstract Denosumab is associated with the development of medication-related osteonecrosis of the jaw (MRONJ), an uncommon but severe oral side effect with a higher prevalence in metastatic cancer patients than in patients with metabolic bone fragility. Although several oral triggers can initiate MRONJ, invasive oral treatments and tooth extraction still remain the most common precipitating event. In general, tooth extraction and oral surgery should be avoided in patients at increased risk of MRONJ, while extraction of non-restorable teeth should be performed based on specific risk reduction protocols to eliminate dental/periodontal infections, still protecting from MRONJ onset. Based on th…

Proliferative verrucous vs conventional leukoplakia: no significantly increased risk of HPV infection

Proliferative verrucous leukoplakia (PVL) is a very aggressive form of oral leukoplakia (OL) with high morbidity and mortality rates, hypothesised to be linked to HPV infection. This study aimed to determine the presence of HPV DNA in PVL in comparison with OL, and in relation to social-demographical variables (age, gender, smoking and drinking habits) in an Italian multi-centric hospital-based study. The study group consisted of 58 cases of PVL and 90 cases of OL as controls (47 homogeneous (H) and 43 non-homogeneous (non-H) form), both recruited from four Italian cohorts. HPV DNA was identified in exfoliated mucosal cells by nested PCR (nPCR) with MY09/MY11 and GP5+/GP6+ primer pairs and …

Effect of desquamative gingivitis on periodontal status: a pilot study

Objective:  Desquamative gingivitis (DG) represents the gingival manifestation associated with several mucocutaneous disorders and systemic conditions. Little is known of whether or not DG could influence the onset or progression of plaque-related periodontitis. In this study, the potential impact of DG on plaque-related attachment loss and pocket formation has been evaluated. Methods:  A cross-sectional evaluation of 12 patients with DG [eight oral lichen planus (OLP), four mucous membrane pemphigoid (MMP)], never treated for DG lesions or plaque-related periodontitis, was carried out. Probing depth (PD), clinical attachment loss (CAL), full-mouth plaque (FMPS), and bleeding (FMBS) scores …

Effectiveness of a new method of disinfecting the root canal, using Er, Cr:YSGG laser to kill Enterococcus faecalis in an infected tooth model.

Some lasers have demonstrated to provide effective disinfection when used as adjunctive device to the conventional treatment. The aim of this in vitro study was to determine the effectiveness of the erbium, chromium:yttrium scandium gallium garnet (Er, Cr:YSGG) laser by measuring its bactericidal effect inside the root canal experimentally colonized with Enterococcus faecalis. The laser was tested at different irradiation times (30 and 60 s) and energy of impulses (75 and 25 mJ). A total of 52 single-rooted extracted human teeth were endodontically prepared with rotary instrumentation. All were sterilized and inoculated with a suspension of E. faecalis (105 bacteria/ml). The teeth were rand…

HPV DNA in clinically different variants of oral leukoplakia and lichen planus

Abstract Objectives Our objectives were to determine the prevalence of human papillomavirus (HPV) infection in oral leukoplakia (OL) and oral lichen planus (OLP) in comparison with that in healthy oral mucosa, also conditionally to age, gender, smoking, and drinking habits of patients, so as to investigate any possible association of HPV infection with a specific clinical variant of OL or OLP. Study design We did research on HPV DNA in 68 cases of OL (homogeneous form [H] in 45 cases and nonhomogeneous form [non-H] in 23 cases), and in 71 cases of OLP (nonatrophic/erosive form [non-AE] in 27 cases, atrophic/erosive form [AE] in 44 cases). HPV DNA was investigated in exfoliated oral mucosa c…

Electrostimulation of the lingual nerve by an intraoral device may lead to salivary gland regeneration: A case series study

Background Salivary gland function is controlled by the salivary reflex, whose efferent arm is composed by the parasympathetic and the sympathetic divisions of the autonomic nervous system. Parenchymal injury is the main salivary gland involvement of Sjögren’s syndrome and head and neck radiotherapy, but neural damage has been reported as well. Recently an intraoral device for electrostimulation of the lingual nerve in vicinity to the lower third molar has been introduced. At this point this nerve carries efferent fibers for the innervation of the submandibular, sublingual and several minor salivary glands and afferent fibers of the salivary reflex. Therefore, excitation of these fibers pot…

Papilloma a cellule squamose orale HPV-negativo: cases report

Oral leishmaniasis in an HIV-infected patient.

As in most countries in the Mediterranean basin, leishmaniasis is endemic in Italy, where it has visceral (VL) and cutaneous (CL) forms caused by viscerotropic and dermotropic strains of Leishmania infantum, respectively. With the spread of the acquired immunodeficiency syndrome (AIDS) epidemic, the number of coinfections with Leishmania and human immunodeficiency virus (HIV) is increasing. Between 35% and 50% of the adult VL cases diagnosed annually in Sicily from 1991 to 1995 were related to HIV [1]; although cases of coinfection have been reported in 28 countries worldwide, the majority of these cases (1440 from 1990 to 1998) have been notified in four countries (Spain, Italy, France, Po…

TLR4 down-regulation identifies high risk HPV infection and integration in head and neck squamous cell carcinomas

TLRs are main actors of the innate immune response against HPV. There are very few studies on the role of TLRs mediated HPV clearance in Head and Neck oncology. Our aim was to evaluate whether TLR4 expression identifies HPV infection and/or HR-HPV integration status in oral and oropharyngeal cancers. By immunohistochemistry we assessed TLR4 levels in OSCC/OPSCC. To detect viral integration or episomic status In situ hybridization for HPV-DNA and Pyro-sequencing techniques have been performed. The relationship between TLR4 expression with HPV infection status has been investigated. ISH HPV positive samples have reported lower levels of TLR4 intensity than negative samples (p = .002). There w…

Comment on Medication-Related Osteonecrosis of the Jaw: MASCC/ISOO/ASCO Clinical Practice Guideline Summary

Legal liability in bisphosphonate-related osteonecrosis of the jaw

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is an adverse reaction that may occur in patients administered with bisphosphonates (BP). This condition can cause high morbidity and hinder quality of life. Its treatment is complex and often unsatisfactory, and prevention strategies may have limited effectiveness, if any. Thus, managing patients treated with BP may result in exposure of the practitioner to legal liability or malpractice claims: legal actions pursuant to BRONJ are reported to be underway on three continents. Nonetheless, the attribution of liability, if any, is a complex process requiring, on the basis of current knowledge, a robust and pragmatic approach to the facts…

Diffusion of naltrexone across reconstituted human oral epithelium and histomorphological features

Abstract In transbuccal absorption a major limitation could be the low permeability of the mucosa which implies low drug bioavailability. The ability of naltrexone hydrochloride (NLX) to penetrate a resembling histologically human buccal mucosa was assessed and the occurrence of any histomorphological changes observed. We used reconstituted human oral (RHO) non-keratinised epithelium as mucosal section and a Transwell diffusion cells system as bicompartmental model. Buccal permeation was expressed in terms of drug flux ( J s ) and permeability coefficients ( K p ). Data were collected using both artificial and natural human saliva. The main finding was that RHO does not restrain NLX permeat…

Odds ratio estimation in the presence of complete OR quasi-complete separation in data

In presence of completely or quasi-completely separated data, the maximum likelihood estimates for the logistic regression parameters do not exist. In medical research the question is of great importance because of the need to obtain finite odds ratios. Statistical packages do not solve the estimation problem with non-overlapped dataset. We suggest to apply the hidden logistic regression model and the MEL estimator of Rousseeuw and Christmas (2003) where a unique solution is graphically obtained by the inspection of the ridge trace of regression parameters (IRT). Alternatively, we inroduce a Cross Validation (CV) based method to choose the regularization parameter. A real data-set on oral c…

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background: Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods: This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, r…

P-cadherin expression and survival rate in oral squamous cell carcinoma: an immunohistochemical study

Abstract Background P-cadherin (P-cad) is a transmembrane molecule involved in the cell-cell adhesion and similar to E-cadherin (E-cad), but less investigated in oncology, especially in in vivo studies. Aims of the present study were to assess the prevalence of P-cad expression in oral squamous cell carcinoma (OSCC) and to verify whether P-cad can be considered a marker of prognosis in patients with OSCC. Methods In a retrospective study, a cohort of 67 OSCC patients was investigated for P-cad expression and its cellular localization by immunohistochemistry; some respective healthy margins of resection were similarly investigated as standard controls. After grouping for P-cad expression, OS…

Brushing of Oral Mucosa for Diagnosis of HPV Infection in Patients with Potentially Malignant and Malignant Oral Lesions

Introduction: Adequate brushing of oral mucosa is important for accurate human papillomavirus (HPV) detection in potentially malignant (oral leukoplakia [OL], oral lichen planus [OLP]) and malignant (oral squamous cell carcinoma [OSCC]) lesions. Since various factors may limit the adequacy of oral brushing and, consequently, the accuracy of HPV detection, modified sampling procedures should be evaluated for their effect on HPV frequency and/or types detected. Aim: To compare the HPV frequency in samples obtained by brushing the lesion site with the frequency in samples obtained by brushing an apparently normal adjacent site. The correlation between HPV frequency and keratinization of the si…

HPV infection in relation to OSCC histological grading and TNM stage. Evalutation by traditional statistics and fuzzy logic model

We aimed to evaluate if in oral squamous cell carcinoma (OSCC) there is a relationship between histological grading (HG), TNM clinical stage and HPV infection; and to study the performance of fuzzy logic compared to traditional statistics, in the analysis of HPV status and correlates of OSCC. In cross-sectional analysis, the study group comprised 63 patients (mean age 68.89 years (SD ± 11.78), range (32–93); males 28 (44.4%), females 35 (55.6%)) with OSCC histologically diagnosed. HPV-DNA was studied in exfoliated oral epithelial cells by nested PCR (MY09/MY11 and GP5+/GP6+ primers). Data were analysed in parallel by traditional statistics with multivariate analysis and a fuzzy logic (FL) t…

Oral local drug delivery and new perspectives in oral drug formulation

Modern pharmaceutical science has provided us with a wide range of substances to be administered with a wide large variety of dosage forms. Local drug delivery systems have been used for a long time; in particular, for the local therapy of diseases affecting the oral cavity. Although these diseases are often extremely responsive to local therapy, the mouth often presents various difficulties in the application of topical compounds (owing to saliva and the mouth's different functions), resulting in a short retention time of dosage forms with a consequent low therapeutic efficacy. To resolve these limitations, research today concentrates on the development of bioadhesive formulations. This re…

Low rate of oral human papillomavirus (HPV) infection in women screened for cervical HPV infection in Southern Italy: A cross-sectional study of 140 immunocompetent subjects.

Even though the natural history of cervical and oral human papillomavirus (HPV) infection has been investigated intensely, the possibility that HPV may infect both sites in the same subject is not well documented. This study investigated the frequency of concurrent oral and cervical HPV infection in southern Italian women, in the light of some selected socio-behavioral variables. One hundred forty women (mean age: 36 years), with known cervical HPV status, were analyzed for oral HPV. Age, smoking/drinking habits, clinical and socio-behavioral history were assessed by personal interviews. Oral mucosal cells were collected by oral brushing and HPV DNA was sought by the use of nested PCR ampli…

ORAL LESIONS DUE TO ACINETOBACTER BAUMANNII INFECTION IN A PATIENT AFFECTED BY AUTOIMMUNE HEMOLYTIC ANEMIA (AIHA): FIRST CLINICAL REPORT

Aim. Acinetobacter Baumannii (coming from the Greek “akinetos,” i.e. non-motile) is an opportunistic bacterial pathogen primarily associated with hospital-acquired infections. Commonly associated with aquatic environments, A. Baumannii easily contaminates the surrounding environment and it colonizes acute ill patients in which can survive for several days. Generally, A. Baumannii is able to damage mucous membranes or exposed skin after accident or injury; it may be responsible of many diseases such as pneumonia, bacteremia, meningitis, urinary tract infections, peritonitis and infections of skin and soft tissues. Tissues infected by A. Baumannii initially present “orange peel” appearance fo…

Oral human papillomavirus infection in women with cervical HPV infection: new data from an Italian cohort and a metanalysis of the literature.

Summary A key issue in oral HPV infection is whether it can be associated with a genital HPV infection, or whether it can be considered as an independent event. This analysis evaluated the frequency and type-concordance of oral HPV infection in women with cervical HPV infection by means of: (i) a cross-sectional study on a sample (n = 98) of Italian women; and (ii) a literature-based metanalysis, including the experimental study the subject of this Paper and nine other published studies (n = 1017), which also examined the influence of oral sampling procedure (oral brushing vs oral rinse) and HIV status on oral HPV detection. The prevalence of oral HPV infection in the Italian study was 14.3…

Biopsy vs. brushing: comparison of two sampling methods for the detection of HPV-DNA in squamous cell carcinoma of the oral cavity

Background: HR HPV infection was proposed as aetiological factor of oral squamous cell carcinomas (OSCC). HPV frequency in OSCC is highly variable, due to the discrepancy in oral sampling procedures, HPV testing methods and inclusion criteria regarding tumour site (strictly oral cavity vs. nearby structures). Our aim was to compare HPV DNA frequency and type-specific distribution in paired cytological and histological samples of SCC strictly located in oral cavity. The correlation between HPV detection rate by each method of sampling and demographical, behavioural and clinical-pathological variables was also examined. Patients and methods: HPV DNA was detected in brushed cells and formalin-…

Bioactive Scaffolds Based on Amine-Functionalized Gellan Gum for the Osteogenic Differentiation of Gingival Mesenchymal Stem Cells

With the aim to produce a cellularized construct for the guided bone regeneration of dento-alveolar defects, here we produce a porous scaffold using an amine derivative of gellan gum to host gingival mesenchymal stem cells (GMSCs) and allow their osteochondral differentiation. Three derivatives were produced by using the same synthetic procedure, and the viscoelastic properties of their aqueous dispersions were investigated and compared to those of the native polysaccharide to choose the derivative with suitable properties for the scaffold production. Freeze-drying was used to obtain a porous sponge that can be rehydrated with the cells’ suspension to produce an implantable cell containing …

Diagnostic delay in oral squamous cell carcinoma: the role of cognitive and psychological variables

This retrospective study investigated, in two cohorts of subjects living in Southern Italy and awaiting treatment for oral squamous cell carcinoma (OSCC), the variables related to diagnostic delay ascribable to the patient, with particular reference to the cognitive and psychological ones. A total of 156 patients with OSCC (mean age: 62 years, M/F: 2.39∶1) were recruited at the Universities of Palermo and Naples. Risk factors related to patient delay included: sociodemographic, health-related, cognitive and psychological variables. The analysis was conducted by considering two different delay ranges: dichotomous (≤1 month vs. >1 month) and polytomous (3 months) delay. Data were investigated…

The patient-doctor relationship: new insights in light of the current Ministerial recommendations regarding Phase 2 of the COVID-19 pandemic

Following the publication of the italian Ministerial recommendations relating to dentistry in Phase 2 of the coViD-19 pandemic (focusing on operational protocols for all dental staff), we believe that the patient/dentist relationship should increasingly take into account the heightened fears and anxious thoughts of patients. this particularly regards patients who are about to undergo dental work. Moreover, dentists should also pay close attention to recent events, which have determined the new recommendations regarding SarS-coV-2 biocontainment. Furthermore, the authors of this paper consider it appropriate to make suggestions and develop interventionist techniques regarding the interface w…

Simplifying the dental/periodontal management of patients with metabolic bone fragility receiving treatment with denosumab

Denosumab (DNB) is a bone-targeted medication used to preserve structural integrity and minimise the risk of fragility fractures in metastatic cancer and metabolic bone disorders. DNB targets and binds RANK Ligand, inhibiting osteoclast maturation, function, and survival. In contrast with nitrogen-containing bisphosphonates (N-BPs), DNB does not bind to hydroxyapatite and incorporate into bone; thus, bone cellular remodelling recovers rapidly after drug suspension. Denosumab has benn linked to the occurrence of osteonecrosis of the jaw (MRONJ), a uncommon but severe oral side effect with a higher prevalence in metastatic cancer patients than in patients with metabolic bone fragility. Althou…

Medium-Term Culture of Primary Oral Squamous Cell Carcinoma in a Three-Dimensional Model: Effects on Cell Survival Following Topical 5-Fluororacile Delivery by Drug-Loaded Matrix Tablets

Since the activity of several conventional anticancer drugs is restricted by resistance mechanisms and dose-limiting side-effects, the design of formulations for local application on malignant lesions seems to be an efficient and promising drug delivery approach. In this study, the effect of locally applied 5-FU on cell death was evaluated both in a SCC4/HEK001 model and in a newly proposed 3D outgrowth model of oral squamous cell carcinoma (OSCC). Initially, the optimal drug dose was established by delivery of solutions containing different amounts of 5-FU. The solution containing 1% (w/v) of 5-FU resulted effective in inducing cell death with complete eradication of cell colonies. Buccal …

Evaluation of Galantamine transbuccal absorption by reconstituted human oral epithelium and porcine tissue as buccal mucosa models: Part I

Over the last decade, interest in delivering drugs through buccal mucosa has increased. As a major limitation in buccal drug delivery could be the low permeability of the epithelium, the aim of this study was to evaluate the aptitude of galantamine, useful in Alzheimer's disease, to penetrate the buccal mucosa. The evaluation of the ability of galantamine to permeate through the buccal epithelium was investigated using two permeation models. Firstly, in vitro permeation experiments were carried out using reconstituted human oral non-keratinised epithelium and Transwell diffusion cells system. Results were validated by ex vivo experiments using porcine buccal mucosa as membrane and Franz typ…

Lipid Nanocarriers-Loaded Nanocomposite as a Suitable Platform to Release Antibacterial and Antioxidant Agents for Immediate Dental Implant Placement Restorative Treatment

Immediate implant placement is a single-stage restorative approach for missing teeth widely used to overcome the ridge remodeling process occurring after dental extractions. The success of this procedure relies on opportune osseointegration in the surrounding tissues. To support this process, a multifunctional nanocomposite, to be applied in the fresh post-extraction socket, was here designed, prepared, and characterized. This formulation consists of quercetin (QRC)-loaded nanostructured lipid carriers (NLCs) entrapped in a chitosan-based solid matrix containing ciprofloxacin (CPX). QRC-NLCs were prepared by homogenization followed by high-frequency sonication, and thereafter this dispersio…

Coeliac disease: Oral ulcer prevalence, assessment of risk and association with gluten-free diet in children.

Aims. Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. Methods. A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. …

Salivary Biomarkers for Oral Squamous Cell Carcinoma Diagnosis and Follow-Up: Current Status and Perspectives.

Oral cancer is the sixth most common cancer type in the world, and 90% of it is represented by oral squamous cell carcinoma (OSCC). Despite progress in preventive and therapeutic strategies, delay in OSCC diagnosis remains one of the major causes of high morbidity and mortality; indeed the majority of OSCC has been lately identified in the advanced clinical stage (i.e., III or IV). Moreover, after primary treatment, recurrences and/or metastases are found in more than half of the patients (80% of cases within the first 2 years) and the 5-year survival rate is still lower than 50%, resulting in a serious issue for public health. Currently, histological investigation represents the “gold stan…

Potential transbuccal delivery of l-DOPA methylester prodrug: stability in the environment of the oral cavity and ability to cross the mucosal tissue

Levodopa (l-DOPA) is the most effective pharmacologic agent in Parkinson's disease and remains the "gold standard". Nevertheless, in long-term treatments, dyskinesias and motor complications can emerge. In this work, the combined use of l-DOPA methylester hydrochloride prodrug (LDME) with transbuccal drug delivery was supposed as a good alternative method to optimize the bioavailability of l-DOPA, to maintain constant plasma levels and to decrease the drug unwanted effects. The effects of environmental pH on buccal delivery of LDME were evaluated ex vivo. The increase of pH value from 5.8 to 6.2 implies an improvement of drug permeation. Since the pH increase causes the raising of hydrolyti…

Human papillomaviruses (HPVs) are a group of host-specific DNA viruses, with a remarkable epithelial cell specificity: they have been reported principally in the ano-genital tract, urethra, skin, larynx, tracheo-bronchial and oral mucosa. More than 100 different HPV types have been identified and classified as high (e.g. 16, 18, 31) or low (e.g. 11, 42, 36) -risk (HR and LR), based on their association with cervical carcinoma. The carcinogenic role of HR-HPV revolves mainly around two of its oncoproteins: HPV-E6 which promotes degradation of the p53 tumour suppressor gene product and HPV-E7 which modifies the pRb tumour suppressor gene product, inhibiting the activity of TGF-beta2. Since th…

Minor salivary gland (MSG) biopsies from patients, controls and parotid gland biopsies from pSS-associated lymphoma were obtained. Quantitative gene expression analysis by TaqMan real-time PCR and immunohistochemistry for IL-40 were performed on MSG. MSG cellular sources of IL-40 were determined by flow-cytometry and immunofluorescence. Serum concentration of IL-40 was assessed by ELISA and cellular sources of I…

Diagnostic pathways and clinical significance of desquamative gingivitis:a review

The term desquamative gingivitis (DG) refers to a clinical manifestation that can be caused by several disorders. Many of them are immunologically mediated; in addition to the oral cavity, they can affect extraoral mucocutaneous sites, e.g., larynx, conjunctiva, esophagus, nasal and genital mucosa, and the skin. The degree of oral, periodontal, and systemic involvement determines the overall morbidity and, sometimes, the mortality of these disorders. We comprehensively review disorders commonly associated with DG and highlight diagnostic pathways, guidelines for differential diagnosis, and oral, periodontal, and systemic implications. More rare conditions are reviewed as well. Mucous membra…

Galantamine delivery on buccal mucosa: permeation enhancement and design of matrix tablets

The most important feature in transbuccal drug delivery is the low drug passage through the buccal mucosa. In our previous work we demonstrated the aptitude of Galantamine to penetrate the buccal tissue. The collected data suggested that Galantamine passively crosses the membrane, but the calculated Js and Kp values showed that the drug amount that crosses the membrane wasn’t sufficient to assure blood therapeutic level. So, in this study, ex vivo permeation tests, using porcine buccal mucosa, were performed in presence of physical or chemical enhancers. No significant differences in penetration rate were observed using chemical enhancers as sodium dehydrocholate, EDTA disodium salt and tri…

The production of the oral mucosa of antiendomysial and anti-tissue-transglutaminase antibodies in patients with celiac disease: a review.

Celiac disease (CD) is a lifelong, T cell—mediated enteropathy, triggered by the ingestion of gluten and related prolamins in genetically susceptible subjects, resulting in minor intestinal mucosal injury, including villous atrophy with crypt hyperplasia and intraepithelial lymphocytosis, and subsequent nutrient malabsorption. Although serological tests for antiendomysial (EMA) and anti—tissue transglutaminase (anti-tTG) autoantibodies are used to screen and follow up on patients with CD, diagnostic confirmation is still based on the histological examination of the small intestinal mucosa. Although the small intestinal mucosa is the main site of the gut involved in CD, other mucosal surface…

Diagnostic Concordance between Optical Coherence Tomography and Histological Investigations for Immune-Mediated Desquamative Gingivitis: Observational Study

Desquamative gingivitis (DG) denotes a heterogeneous immune-mediated disease for which early diagnosis represents a great challenge. The main aim of this study is to validate diagnostic concordance between specific Optical Coherence Tomography (OTC) patterns for DG related to oral Lichen Planus (OLP), Pemphigus Vulgaris (PV), and Mucous Membrane Pemphigoid (MMP) and definitive histological diagnosis. Forty-three patients with suspected immune-mediated DGs, were progressively recruited. Before biopsy, an OCT preliminary evaluation was performed using specific pre-determined OCT diagnostic patterns (i.e., morphology and localization of blisters, status of the basal membrane, epithelial thickn…

Peri-Tumoral Inflammatory Cell Infiltration in OSCC: A Reliable Marker of Local Recurrence and Prognosis? An Investigation Using Artificial Neural Networks

The presence of inflammatory reaction in peri-tumoural connective tissue is generally considered as a defense mechanism against cancer, but inflammation tissue in malignant transformation and early steps of oncogenesis has been recently proven to play a supporting and aggravating role in some carcinomas. Aims of this retrospective study were to evaluate in OSCCs the independent association of peri-tumoral inflammatory infiltrate (PTI) with local recurrence (LR) or survival outcome, and to verify whether PTI can be considered a marker of prognosis. Data from 211 cases of OSCC, only surgically treated between 1990 and 2000, were collected and retrospectively analyzed for PTI and the event LR…

Human papillomaviruses in oral carcinoma and oral potentially malignant disorders: a systematic review

Oral Diseases (2011) 17 (Suppl. 1), 58–72 Objectives:  Human papillomavirus (HPV) in oral carcinoma (OSCC) and potentially malignant disorders (OPMD) is controversial. The primary aim was to calculate pooled risk estimates for the association of HPV with OSCC and OPMD when compared with healthy oral mucosa as controls. We also examined the effects of sampling techniques on HPV detection rates. Methods:  Systematic review was performed using PubMed (January 1966–September 2010) and EMBASE (January 1990–September 2010). Eligible studies included randomized controlled, cohort and cross-sectional studies. Pooled data were analysed by calculating odds ratios, using a random effects model. Risk o…

Clinical Evaluation of a Telemedically Linked Intraoral Drug Delivery System

The miniaturized intraoral drug delivery system BuccalDose is composed of a replaceable cartridge which is worn in a removable prosthesis and an external base station for telemedical therapy monitoring. The system has now been tested for the first time with Parkinson’s disease (PD) patients. The study evaluated the usability of the entire system, the functionality of the telemedical transmission path and the functionality of the cartridge, which uses an osmotic pumping principle to release a liquid drug formulation to the buccal mucosa. The BuccalDose system was generally considered to be easy to handle, even with movement disorders, up to a mild-moderate disease stage. In addition, the obt…

Spray-Dried Cytisine-Loaded Matrices: Development of Transbuccal Sustained-Release Tablets as a Promising Tool in Smoking Cessation Therapy

Cytisine (CYT) has emerged as a promising molecule to treat nicotine addiction, since it acts as a partial agonist of nicotinic acetylcholine receptors. However, its unfavorable pharmacokinetic properties lead to multiple administrations per day, reducing the patient’s compliance and increasing the side effects. To overcome these drawbacks, CYT buccal administration is here proposed. Firstly, CYT stability in the buccal environment was assessed and its intrinsic ability to permeate/penetrate the tissue was determined by applying CYT solutions at increasing concentrations. Furthermore, a spray-drying method was selected and optimized as it is an eco-friendly, easily scalable and effective te…

SALIVARY PROTEOME ANALYSIS BY 2D-PAGE AND SELDI-TOF/MS TO SEARCH POTENTIAL BIOMARKERS OF ORAL SQUAMOUS CELL CARCINOMA

Aim. Oral squamous cell carcinoma (OSCC) is the most common malignant tumor of the oral cavity and is a neoplasia characterized by a poor prognosis. In fact, the estimated survival rate is 44% after 5 years from the diagnosis. The prognosis of the disease is significantly related to the stage in which the disease is diagnosed. Moreover the therapies are not very efficient and are so invasive, disfiguring and debilitating that in the survivors the quality of life is poor. Nowadays there is not a reliable and non-invasive method for early diagnosis of oral squamous cell carcinoma and the simple visual examination of the oral cavity is characterized by a low sensitivity and specificity, also b…

Novel non-invasive Adjunctive Techniques for Early Oral Cancer Diagnosis and Oral Lesions Examination

Oral cancer is a potentially fatal disease with an increasing incidence and an unchanged 5-year mortality rate. Unfortunately, oral cancer is often still late diagnosed, which leads to an increase in the likelihood of functional impairment due to treatment and mortality rate. Definitive diagnosis of oral cancer must be confirmed by scalpel biopsy and histological assessment. However despite its benefits, scalpel biopsy is invasive and it is burdened by a potential morbidity. Furthermore, previous studies have suggested a high degree of intraobserver and interobserver variability regarding the histological evaluation of malignancy. As a consequence, in recent years there has been a growing a…

PRIMARY ORAL MUCOSA MELANOMA: A REPORT OF AN UNUSUAL CLINICOPATHOLOGICAL CASE

Primary oral melanoma is a rare malignancy with an aggressive behaviour. Up to date, the wide clinicalhistological variability of this oncological entity does not clarify the etiopathogenetic characteristics of these cancers and limit the therapeutic strategies. We report a case of a 64-year-old white female referred to the Dept. of Surgical, Oncological and Oral Sciences for a pigmented lesion of the mandibular gingiva, already arising 20 years ago but dimensionally increased in the last three months. Clinically, a black plaque-like pigmentation of the vestibular alveolar mucosa of the mandible (from 3.6 to 3.3) was observed. This lesions was still painless. CT dentalscan and ecography of …

Protocol of BRONJ prevention: successful use of antiseptics during oral surgical procedures

Aim: The overall prevention and treatment of Bisphosphonates related osteonecrosis of the jaws (BRONJ) have been the goals of our project structured (labelled PROMaB) within the hospital AOUP “P. Giaccone” (Italy) in order to make better quality life of patients in therapy with amminobisphosphonates (NBP). Material and Methods: Among all procedures, in case of preprogrammed oral surgical procedure, oral antimicrobial rinses (i.e. chlorexidine 0,2% mouthwash and 0,5% gel, three times/day) plus oral systemic antibiotic therapy –e.g. amoxicilin/clavulanate- have been used to reduce the risk of BRONJ in secondary prevention (1 day before and 6 days after). Three hundred and twenty-one patients …

Antibiotic prophylaxis in dentistry and oral surgery: use and misuse

INTRODUCTION: Antibiotic prophylaxis (AP) still represents a common but often misused procedure in dental practice, thus aggravating the risk for antimicrobial resistance and adverse effects occurrence. AIMS AND METHODS: Our primary objective is to review the available scientific evidence regarding AP in dentistry both among healthy subjects and medically compromised patients. Additionally, the latest available guidelines provided by some of the most authoritative associations are here discussed. RESULTS AND CONCLUSIONS: AP is advisable only in a small percentage of patients where a risk of severe infective complications (i.e. infective endocarditis and prosthetic joint infection, septicaem…

The pathophysiology of aging bone jaw: primary and secondary prevention

The skeleton is composed of approximately 200 bones, and it is the backbone of our body along with ligaments and joints. The bone is not a static but a dynamic structure, constantly reshuffling, that may suffer fractures due to trauma, despite their particular hardness and strength. Complex physiologic mechanisms, sometimes with the help of surgery, can lead to bone repairing. In the elderly, often, the skeletal system can be affected by osteoporosis, a "silent disease" that causes fragile bones especially of the vertebrae and femur; its contributing factors are menopause (in women), smoking, nutritional deficiencies, systemic diseases or prolonged use of drugs. The masticatory apparatus an…

Learning from experience. Proposal of a refined definition and staging system for bisphosphonate-related osteonecrosis of the jaw (BRONJ)

Dear Editor, It is the authors’ belief that the internationally accepted definition of bisphosphonate-related osteonecrosis of the jaws (BRONJ) (Ruggiero et al, 2009) has several limitations that prevent clinicians from being confident with the diagnosis of the disease. Following recognition of the non-exposed BRONJ clinical variant (Lazarovici et al, 2009), we all became aware that the presence of ‘exposed necrotic bone in the oral cavity’, as outlined in the American Association of Oral and Maxillofacial Surgery (AAOMS) case definition, is just one of the possible clinical manifestations of BRONJ and is not found in all BRONJ patients. As ‘bone exposure’ is certainly not the initial sign …

The role of antibiotic prophylaxis in reducing bacterial contamination of autologous bone graft collected from implant site

The aim of this study was to evaluate if antibiotic prophylaxis reduces the bacterial contamination of bone particles collected directly from the burs used for implant site preparation. Thirty-four patients underwent the surgical procedures for a total of 34 implant sites. One 1 gr. tablet of amoxicillin + clavulanic acid was given to the test group 12 hours and 1 hour before the surgery. The control group did not take antibiotic prophylaxis. Bone particles were collected and centrifuged. The suspensions were subjected to serial dilutions and each dilution was examined twice using a spatulation technique in Trypticase Soy Agar (TSA), in Sabouraud Dextrose Agar, and in Mitis Salivarius Agar …

Effects of p63 expression on survival in oral squamous cell carcinoma

BACKGROUND: P63 is the protein codified by p63 gene, a p53 gene homolog, known for its pivotal role in cell cycle regulation, and involved in the tumor differentiation. Aims of the present study were to assess the frequency and pattern of p63 protein expression in oral squamous cell carcinoma (OSCC) in relation to the main tumour characteristics and to verify whether p63 can be considered a marker of prognosis in patients with OSCC. MATERIAL AND METHODS: In a retrospective study, a cohort of 64 OSCC patients was investigated for p63 protein expression and its cellular localization by immunohistochemistry (monoclonal mouse anti-human p63 protein-clone 4A4). After grouping by p63 expression, …

PATIENTS AND METHODS: 200 patients with GERD and 100 matched healthy controls were studied. Thorough visual examination of the dental and oral mucosal tissues was performed and medical history relevant to oral symptoms was collected. The primary outcome was defined as a statistically significant difference, between the study group and controls, in the presence of the following indicators: soft/hard palate and uvula erythema, tooth wear, xerostomia, oral acid/burning sensation, subjective halitosis and dental sensitivity. Statistical analysis include…

Quercetin-Based Nanocomposites as a Tool to Improve Dental Disease Management

The restoration and prosthetic rehabilitation of missing teeth are commonly performed using dental implants, which are extremely effective and long-lasting techniques due to their osteointegration ability with the preimplant tissues. Quercetin is a phytoestrogen-like flavonoid well known for its several positive effects on human health, mostly linked to the anti-inflammatory, antioxidant, and antibacterial activities against both Gram-positive and Gram-negative bacteria. Moreover, many studies in dentistry and the maxillofacial fields have highlighted the positive effects of quercetin on osteogenesis, acting on osteoblast activity and angiogenetic process, and promoting soft and hard tissue…

ORAL MANIFESTATIONS IN GASTROESOPHAGEAL REFLUX DISEASE

The gastroesophageal reflux (passage of gastric contents into the oesophagus and the mouth) is the main sign/symptom of a very frequent gastroesophageal reflux disease. Thus, acid regurgitation originates from stomach and it is responsible of the onset of tipical symptoms and mucosal injury. Also in oral cavity the noxious acid agent is able to injure oral cavity (soft and hard tissues). These involvementes are described from international literature, even if a greater interest has shown to date only for hard tissue injury.

The Treatment of Medication-Related Osteonecrosis of the Jaw (MRONJ): A Systematic Review with a Pooled Analysis of Only Surgery versus Combined Protocols

Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse reaction of antiresorptive and antiangiogenic agents, and it is also a potentially painful and debilitating condition. To date, no specific studies have prospectively evaluated the efficacy of its treatment and no robust standard of care has been established. Therefore, a systematic review (2007–2020) with a pooled analysis was performed in order to compare MRONJ surgical techniques (conservative or aggressive) versus combined surgical procedures (surgery plus a non-invasive procedure), where 1137 patients were included in the pooled analysis. A statistically significant difference in the 6-month improvement rate, comp…

Paraneoplastic Acanthosis Nigricans Maligna

Acanthosis Nigricans Maligna (ANM) is a paraneoplastic syndrome, defined as a condition that arises in association with a malignancy elsewhere in the body but without malignant nature per se. It’s a rare dermatopathy that occurs in men and women over age 40, without racial predilection or known familial association. Clinically, ANM showed symmetric,hyperpigmented plaques with variable amounts of epidermal hypertrophy, ranging in color from yellow to brown or black, often with overlaid papillomas. The most common affected sites are body flexures and the posterior neck, but also mucosal surface involvement is frequent and may be the only clinical symptom present. Any mucosal surface can be in…

BYOTYPES AND RANDOMLY AMPLIFIED POLYMORPHIC DNA (RAPD) PROFILES OF SUBGINGIVAL CANDIDA ALBICANS ISOLATES IN HIV INFECTION

ABSTRACT: A group of subgingival isolates of C. albicans recovered from Italian HIV-positive (HIV+) subjects were characterized both phenotypically and genotypically. Phenotyping of the isolates was carried out by a biotyping method based on the enzyme profiles, carbohydrate assimilation patterns and boric acid resistance of the yeasts. Genotyping was performed through randomly amplified polymorphic DNA (RAPD) analysis. Five biotypes were found among the 29 subgingival C. albicans strains examined. The predominant biotypes were A1R (55.17%), A1S (24.14%), and A2R (13.79%), while the biotypes A11R and A13R were represented by a single isolate each. RAPD profiles identified 15 genotypes among…

Review of: "OSTEONECROSIS OF THE JAW (ONJ) IN BREAST CANCER PATIENTS: EFFECT OF PREVENTIVE MEASURES IN A MONOINSTITUTIONAL EXPERIENCE"

Gingivitis

Key Highlights - Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing ulcerative gingivitis (NUG) is a more serious condition that is mainly found in developing countries associated with people with severe malnutrition or HIV/AIDS with low CD4 T-cell counts.

Low Frequency of Human Papillomavirus in Strictly Site-Coded Oral Squamous Cell Carcinomas, Using the Latest NHI/SEER-ICD Systems: A Pilot Observational Study and Critical Review.

Simple Summary The incidence of oropharyngeal squamous cell carcinomas (OPSCCs) has increased in the last decades, and this seems to be correlated to the infectious epidemiological trend of human papillomavirus (HPV). The prevalence of HPV-positive OPSCCs is approximately 70%, with involvement mainly of the tonsillar area. On the role of HPV in oral squamous cell carcinoma (OSCC), very few studies have investigated the prevalence of HPV in strictly site-codified OSCC, excluding the base of the tongue as distinct oropharyngeal entity. As a result, an inappropriate estimation of HPV infection in OSCC has been observed. We investigated HPV status, using a combination of detection methods, in a…

MMP-10/stromelysin-2 promotes invasion of head and neck cancer.

BackgroundPeriostin, IFN-induced transmembrane protein 1 (IFITM1) and Wingless-type MMTV integration site family, member 5B (Wnt-5b) were previously identified as the invasion promoted genes of head and neck squamous cell carcinoma (HNSCC) by comparing the gene expression profiles between parent and a highly invasive clone. We have previously reported that Periostin and IFITM1 promoted the invasion of HNSCC cells. Here we demonstrated that Wnt-5b overexpression promoted the invasion of HNSCC cells. Moreover, stromelysin-2 (matrix metalloproteinase-10; MMP-10) was identified as a common up-regulated gene among Periostin, IFITM1 and Wnt-5b overexpressing HNSCC cells by using microarray data s…

Commonalities between ENT Specialists and Oral Medicine Experts: Old HPV Diseases and New Oral HPV-Cancer along the Borders

A human papillomavirus (HPV) infection is globally one of the most common causes of sexually transmitted infections of the mucous membranes (genital, anal and oral). Over the last decade, an increasing number of young patients have been infected due to the changes in sexual habits in the general population. The majority of the lesions are benign; however, substantial scientific evidence has suggested a role for the HPV family in the carcinogenesis of squamous cell carcinoma (SCC). It is proposed that dentists, in addition to ENT specialists, should apply standardized management protocols in order to construct a well-defined pathway in terms of diagnosis, which is based on a PCR diagnostic t…

Growth and Osteogenic Differentiation of Discarded Gingiva-Derived Mesenchymal Stem Cells on a Commercial Scaffold

Background In periodontal patients with jawbone resorption, the autologous bone graft is considered a "gold standard" procedure for the placing of dental prosthesis; however, this procedure is a costly intervention and poses the risk of clinical complications. Thanks to the use of adult mesenchymal stem cells, smart biomaterials, and active biomolecules, regenerative medicine and bone tissue engineering represent a valid alternative to the traditional procedures. Aims In the past, mesenchymal stem cells isolated from periodontally compromised gingiva were considered a biological waste and discarded during surgical procedures. This study aims to test the osteoconductive activity of FISIOGRAF…

Interleukin (IL)-22 receptor 1 is over-expressed in primary Sjogren's syndrome and Sjögren-associated non-Hodgkin lymphomas and is regulated by IL-18.

Summary The aim of this study was to elucidate more clearly the role of interleukin (IL)-18 in modulating the IL-22 pathway in primary Sjögren's syndrome (pSS) patients and in pSS-associated lymphomas. Minor salivary glands (MSGs) from patients with pSS and non-specific chronic sialoadenitis (nSCS), parotid glands biopsies from non-Hodgkin lymphomas (NHL) developed in pSS patients, were evaluated for IL-18, IL-22, IL-22 receptor 1 (IL-22R1), IL-22 binding protein (IL-22BP) and signal transducer and activator of transcription-3 (STAT-3) expression. MSGs IL-22R1-expressing cells were characterized by confocal microscopy and flow cytometry in pSS, nSCS and healthy controls. The effect of recom…

Unusual presentation of a solitary plasmocytoma of the jaw: a case report

Introduction. Plasma cell malignancies include two localized forms (e.g. Solitary Plasmocytoma of the Bone-SPB- and Extramedullary Plasmocytoma-EMP) and one more severe disseminated form (e.g. Multiple Myeloma-MM). SPB usually affected male during 6th decades, it occurs as a single uni- or multilocular osteolytic lesion, histopathological- ly characterized by an abnormal proliferation of plasma cell. In some patients SPB may progress to MM, character-ized by multiple osteolytic lesion in several bones, presence of abnormal plasma cells in the bone marrow biopsy, detection of amyloid deposit and abnormalities of immunoglobulin production. In both clinical forms, the maxillofacial area is rar…

P254 Survivin detection in saliva samples from patients with oral squamous cell carcinoma

In vivo optical coherence tomography imaging in a case of mucous membrane pemphigoid and a negative Nikolsky's sign.

There is currently a growing interest in new diagnostic tools of the oral cavity and mucosa which are non-invasive, repeatable and reliable. A diagnosis of a suspected, autoimmune pathology was made regarding a 57-year-old patient with desquamative gingivitis. However, a negative Nikolsky's sign did not seem to indicate a diagnosis of mucous membrane pemphigoid neither was there any indication as to the optimum location for an incisional biopsy. As an imaging method, the use of optical coherence tomography (OCT) has enabled the obtaining of tomographic (cross-sectional) scans of tissue. Such images are acquired prior to and after verifying Nikolsky's sign, thereby enabling the clinician to …

Hypoxia inducible factor-1 alpha expression is increased in infected positive HPV16 DNA oral squamous cell carcinoma and positively associated with HPV16 E7 oncoprotein.

Abstract Background There is increasing evidence for the role of High Risk (HR) Human PapillomaVirus (HPV) in the pathogenesis of Oral Squamous Cell Carcinoma (OSCC). The E6 and E7 oncogenes from HR HPVs are responsible for the deregulation of p53 and pRB proteins involved in cell cycle and apoptotic pathways. In cell lines experiments, the HPV E7 protein seems to be able to enhance Hypoxia Inducible Factor-1 alpha (HIF-1α) activity, normally involved in the response to hypoxia and able to enhance angiogenesis. Results We studied tumor specimens from 62 OSCC; a higher prevalence of tumors in TNM stage II and also in pT2 class between OSCC infected positive HPV16 DNA than non-infected ones w…

Periodontal disease and systemic diseases: interrelationships and interactions

The focal infection theory, which for almost half a century justified indiscriminate extraction of teeth to cure focal infections, since the end of the 1940s has become progressively a discarded concept. In parallel with the declining importance assigned to pulp and periapical infections in the pathogenesis of focal diseases, over the last decade there has been increasing interest in the possible relationship between periodontal infection and systemic diseases. Periodontal pathogens and their products, as well as inflammatory mediators produced in gingival tissue, might enter the bloodstream through ulcerated pocket epithelium, causing systemic effects (focal diseases). On the basis of this…

Human papillomavirus: Its identikit and controversial role in oral oncogenesis, premalignant and malignant lesions (Review)

Human papillomaviruses (HPVs) are a group of host-specific DNA viruses, with a remarkable epithelial cell specificity: they have been reported principally in the ano-genital tract, urethra, skin, larynx, tracheo-bronchial and oral mucosa. More than 100 different HPV types have been identified and classified as high (e.g. 16, 18, 31) or low (e.g. 11, 42, 36) -risk (HR and LR), based on their association with cervical carcinoma. The carcinogenic role of HR-HPV revolves mainly around two of its oncoproteins: HPV-E6 which promotes degradation of the p53 tumour suppressor gene product and HPV-E7 which modifies the pRb tumour suppressor gene product, inhibiting the activity of TGF-beta2. Since th…

The preventive care of medication-related osteonecrosis of the jaw (MRONJ): a position paper by Italian experts for dental hygienists

Abstract Purpose The prevention and early diagnosis of medication-related osteonecrosis of the jaw (MRONJ) is fundamental to reducing the incidence and progression of MRONJ. Many in the field believe that dental hygienists should play an integral role in primary and secondary MRONJ prevention. However, to date, very few publications in the literature have proposed standardised MRONJ protocols, which are dedicated to dental hygienists. The aim of this study was to provide guidance to the health care providers managing MRONJ. Methods The expert opinion in this study was developed by dental hygienists from the main Italian technical-scientific associations (Italian Dental Hygienists Associatio…

Malattia parodontale e malattia cardiovascolare: correlazione o semplice coincidenza? Revisione della letteratura

The present paper reviews relationship between chronic periodontitis and cardiovascular diseases. Original papers on this subject, published in English in the period between 2001 and the first semester 2006, were located in the MEDLINE/PubMed database. Additional studies were obtained by searching reference lists of previously published papers. Periodontal infection provides a chronic reservoir of inflammatory mediators and cytokines, lipopolysaccharide, which contribute to the formation of atheroma. Moreover, periodontal pathogens can penetrate the epithelial barrier of the periodontal tissues and reach the blood stream, carrying out a local atherogenic activity. Some studies indicated tha…

Diagnostic Pathways and Clinical Significance of Desquamative Gingivitis

The term desquamative gingivitis (DG) refers to a clinical manifestation that can be caused by several disorders. Many of them are immunologically mediated; in addition to the oral cavity, they can affect extraoral mucocutaneous sites, e.g., larynx, conjunctiva, esophagus, nasal and genital mucosa, and the skin. The degree of oral, periodontal, and systemic involvement determines the overall morbidity and, sometimes, the mortality of these disorders. We comprehensively review disorders commonly associated with DG and highlight diagnostic pathways, guidelines for differential diagnosis, and oral, periodontal, and systemic implications. More rare conditions are reviewed as well. Mucous membra…

ENDOCANNABINOIDS CB1 AND CB2: A POSSIBLE ROLE IN ORAL SQUAMOUS CELL CARCINOMA PATHOGENESIS

Aim. Cancer of the oral cavity is the eighth most common malignancy in the world. The disease is diagnosed after a considerable delay and predict the individual progression is difficult. The improvements of the therapy did not increased the rate of survival at 5 years, that is still about 50%. The identification of the possible markers that indicates the progression of the tumor is therefore necessary. Endocannabinoids may play an important role in the process of carcinogenesis in the oral mucosa. They are able to bind and activate specific membrane receptors coupled to G proteins, cannabinoid receptors CB1 and CB2. The purpose of this study is to evaluate the expression of CB1 and CB2 rece…

What happens to the BRONJ patients when re-classified according to the novel SICMF-SIPMO recommendations? Our experience

Background. Since 2009, according to the American Association of Oral and Maxillofacial Surgeons staging system (AAOMS-SS), Bisphosphonate Related Osteonecrosis of the Jaw (BRONJ) has been defined by the presence of bone exposition; in absence of this condition, patients presenting other unspecific clinical and/or radiological signs of disease were classified into the “stage 0”. In 2012, the Italian Society of Maxillo-Facial Surgery (SICMF) and the Italian Society of Oral Pathology and Medicine (SIPMO) redefined BRONJ, as an adverse drug event, with several clinical forms (exposed and not-exposed), and updated the staging system, abolishing the stage 0. Aim of this study was to re-classify …

Carbamazepine transbuccal delivery: the histo-morphological features of reconstituted human oral epithelium and buccal porcine mucosae in the transmucosal permeation.

Transbuccal drug delivery is an attractive way of administration since several well-known advantages are provided, especially with respect to peroral management. Carbamazepine (CBZ) is an anticonvulsant which is useful in controlling neuropathic pain, and it is currently administered by peroral route, although its absorption and bioavailability is limited due to various factors. The oral cavity could be an interesting site for transbuccal CBZ delivery due to two properties: slow administration of constant low drug doses and less dose-related side effects. However, in transbuccal absorption a major limitation could be the low permeability of the mucosa which results in low drug bioavailabil…

Expression of sexual hormones receptors in oral squamous cell carcinoma.

Sexual hormones play an important role in expression of genes involved in a wide variety of biological and neoplastic processes. The information on Estrogen Receptors (ER) expression in non-target tissues is very few and, in particular, the studies in head and neck tumors are still controversial. Recent studies analyzed the role of Tamoxifen (TAM) on Oral Squamous Cell Carcinoma (OSCC) lines in relation to the presence/absence of ER. The purpose of the present study was to evaluate the expression of sexual hormones receptors mRNAs, in particular Estrogen Receptor alpha (ERα) and Androgen Receptor (AR) mRNA in OSCC tissues.

Can radium 223 be a conservative non-surgical management of medication-related osteonecrosis of the jaw?

AbstractOsteonecrosis of the jaw (ONJ) is a rare and severe necrotic bone disease reflecting a compromise in the body's osseous healing mechanisms and unique to the craniofacial region. Radium 223 dichloride (Ra223) is the only targeted alpha therapy able to extend survival in patients with bone metastases from prostate cancer. Mechanism of action and data currently available focused mainly on osteoblastic metastases from prostate cancer. In 2018, a Caucasian 54-year-old woman presented to our institution for a breast cancer with bone metastases. Since the patient refused any treatment and taking into account the bone disease, our multidisciplinary team evaluated a supplementary strategy wi…

5-Fluorouracil Buccal Tablets for Locoregional Chemotherapy of Oral Squamous Cell Carcinoma: Formulation, Drug Release and Histological Effects on Reconstituted Human Oral Epithelium and Porcine Buccal Mucosa

5-Fluorouracil (5-FU) is currently used for treatment of oral squamous cell carcinoma (OSCC). 5-FU is given by i.v. although the systemic administration is associated with severe toxic effects and no topical formulations of 5-FU for buccal drug delivery have been reported. In this study we would report the development of buccal tablets suitable for direct application of low-doses of 5-FU on cancer lesions. The topical administration could be effective on tumor area while systemic undesired side effects are avoided. Preliminarily, the limited tendency of 5-FU to cross the buccal tissue was established using reconstituted human oral epithelium (RHOE, in vitro) and porcine buccal mucosa (ex vi…

Potential involvement of IL-22 and IL-22-producing cells in the inflamed salivary glands of patients with Sjogren's syndrome.

OBJECTIVES: In chronic inflammatory disorders, interleukin (IL)-22 may act either as a protective or as a pro-inflammatory cytokine. At mucosal sites, IL-22 is mainly produced by CD4(+) T cells and by a subset of mucosal natural killer (NK) cells expressing the receptor NKp44 (NKp44(+) NK cells). The aim of this study was to investigate the IL-22 expression in the salivary glands of patients with primary Sjögren's syndrome (pSS). METHODS: Minor salivary gland biopsies were obtained from 19 patients with pSS and 16 with non-specific chronic sialoadenitis. Quantitative gene expression analysis by TaqMan real-time PCR and immunohistochemistry for IL-17, IL-22, IL-23 and STAT3 (signal transduce…

Oral Squamous Cell Carcinoma Mimicking Medication-Related Osteonecrosis of the Jaws (MRONJ): A Case Series

(1) Background: Medication-related osteonecrosis of the jaw (MRONJ) is a potential adverse drug reaction of antiresorptive and/or antiangiogenic treatment. MRONJ is mostly diagnosed by anamnestic data, clinical examination and radiological findings, with signs and symptoms often unspecific. On the other hand, oral squamous cell carcinoma (OSCC) is characteristic for its pleomorphic appearance (e.g., ulcer, mucous dehiscence, non-healing post-extractive socket). We report three cases where OSCC mimicked MRONJ lesions. (2) Patients: Three patients undergoing amino-bisphosphonate treatment for osteoporosis presented with areas of intraorally exposed jawbone and unspecific radiological signs co…

Scialoadeniti ostruttive.Aggiornamento in tema di diagnosi e di terapia

In head and neck district, major salivary gland diseases seem to have a considerable epidemiological and clinical impact, especially in obstructive disease. Major salivary glands, in fact, having a ductal system can develop several diseases: sialoadenitis, sialodochitis and sialoceles. Particularly, the obstructive sialoadenitis, with or without sialolithiasis, are the most frequent inflammatory disorder, especially for submandibular gland. In the clinical practice, the diagnostic approach for obstructive sialoadenitis up to now consisted of traditional Rx, ultrasonographic technique, scintigraphy technique, C.T., sialography technique with contrast or sialography M.R. Since '9O years, lith…

Gingivitis

Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing gingivitis (NG) is a more serious condition that is mainly found in developing countries and is associated with people with severe malnutrition or people living with HIV with low CD4 counts.

Medication-Related Osteonecrosis of Jaws (MRONJ) Prevention and Diagnosis: Italian Consensus Update 2020

The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference—held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) (20 October 2018, Ancona, Italy)—after the newest recommendations (2020) on MRONJ were published by two scientific societies (Italian Societies of Maxillofacial Surgery and Oral Pathology and Medicine, SI…

Medium-term Culture of Normal Human Oral Mucosa: A Novel Three-dimensional Model to Study the Effectiveness of Drugs Administration

Tissue-engineered oral mucosal equivalents have been developed for in vitro studies for a few years now. However, the usefulness of currently available models is still limited by many factors, mainly the lack of a physiological extracellular matrix (ECM) and the use of cell populations that do not reflect the properly differentiated cytotypes of the mucosa of the oral cavity. For this reason, we have developed a novel three-dimensional culture model reflecting the normal architecture of the human oral mucosa, with the main aim of creating a better in vitro model where to test cellular responses to drugs administration. This novel 3D cell culture model (3D outgrowth) was set up using an arti…

Oral lichenoid drug reaction by lithium in a patient with bipolar disorder

Bipolar disorder (BD) is a psychiatric disease characterized by recurrent and alternated episodes of depression and mania. For the treatment of BD, anticonvulsants drugs as lithium, carbamazepine and oxcarbazepine can be used. These drugs can be associated with potential adverse effects: weight gain, tremors, thyroid abnormalities, and cognitive, gastrointestinal, cardiac or dermatological problems. We describe a case of BD with oral lichenoid drug reaction probably because of the mood stabilizers.

The role of the innate immune response in HPV-related oral and oropharyngeal cancer

Introduction. During the last 20 years, the incidence of HPV-associated oropharyngeal cancer is increased. Principal actors of the innate immune response against HPV are represented by the TLRs (Toll like receptors). On the other hand different studies have reported that HPV can directly inhibit the functions of the TLRs pathway through interferons (IFNs). There are very few preliminary studies on the role of TLRs mediated HPV clearance in human oncology. Our study aim has been to evaluate whether TLR4 identifies HR-HPV integration state in OSCC. Methods. Protein levels of TLR4 in OSCC were assessed using Immunohistochemistry (IHC). In situ hybridization (ISH) for HPV-DNA detection in morph…

Osteonecrosis of the jaw after adjuvant endocrine therapy plus alendronate in a breast cancer patient

Background. Bisphosphonates-associated osteonecrosis of the jaws (BRONJ) is a serious complication, which has been defined by Bedogni et al. (1) as an adverse drug reaction consisting of progressive destruction and death of bone that affects the mandible and/or maxilla of patients exposed to the treatment with nitrogen-containing bisphosphonates (NBPs) in absence of a previous radiation treatment. Generally, IV NBPs have a strong association with BRONJ than oral NBPs as evidenced by the higher incidence of BRONJ (0-10%) in patients treated with IV drugs than in patients in oral therapy (<1%). Objectives. The aim of this study was to report a clinical case of BRONJ in an oncologic patient wh…

CBCT in the diagnosis of osteonecrosis of the jaws

Short Summary: ONJ is associated with bisphosphonates, and recently with antiangiogenic drugs. Another cause is radiotherapy. Few papers have previously investigated the value of CBCT in the diagnosis of ONJ. Purpose/Objectives: To describe the CBCT findings in the diagnosis of osteonecrosis of the jaws (ONJ) according to a new staging system of ONJ. Methods and Materials: 9 patients (5 women, 4 men, 54-76 yrs.) affected by ONJ were studied with a CBCT device (90 kV, 12.5 mA, 0.25 mm voxel size) in 2012-2013. 7/9 patients were treated with bisphosphonates (5 for bone metastasis, 2 for osteoporosis), 1/9 patient was treated with an antiangiogenic drug, 1/9 patient received radiotherapy. Pati…

No findings of dental defects in children treated with minocycline

Thanks to their broad antimicrobial spectrum, tetracyclines were found to be valuable for the treatment of many infections (10). Unfortunately, they irreversibly bind to calcifying tissues and are deposited along the incremental lines of dentine and enamel, causing defects and staining, from bright yellow to dark brown (3, 5, 8). According to the American Academy of Pediatrics, tetracyclines are not indicated for the treatment of common infections in children younger than 8 years of age. However, doxycycline (a tetracycline analogue) is recommended for treatment of Rocky Mountain spotted fever in children of any age (1). Minocycline has several advantages over other tetracyclines: it is bet…

Unexpected high frequency of genital involvement in women with clinical and hostological features of oral lichen planus

The main aims of this cross-sectional study were: (i) to assess the frequency of genital (vulval) lichen planus (VLP) and vulval lichen sclerosus (VLS) in women affected with oral lichen planus (OLP), regardless of the genital symptoms reported; and (ii) to verify whether any demographic, clinical, or histological features of OLP are associated with a higher risk of vulvo-vaginal involvement. Fifty-five women, presenting OLP, consecutively underwent gynaecological examination and, if they demonstrated positive clinical signs of VLP, underwent biopsy. After a drop-out of 14 subjects, 31/41 (75.6%) were found to have signs of genital involvement, of which 13/31 (44.0%) were asymptomatic. Foll…

Improvement of Resveratrol Permeation through Sublingual Mucosa: Chemical Permeation Enhancers versus Spray Drying Technique to Obtain Fast-Disintegrating Sublingual Mini-Tablets

Resveratrol (RSV) is a natural polyphenol with several interesting broad-spectrum pharmacological properties. However, it is characterized by poor oral bioavailability, extensive first-pass effect metabolism and low stability. Indeed, RSV could benefit from the advantage of the sublingual route of administration. In this view, RSV attitudes to crossing the porcine sublingual mucosa were evaluated and promoted both by six different chemical permeation enhancers (CPEs) as well as by preparing four innovative fast-disintegrating sublingual mini-tablets by spray drying followed by direct compression. Since RSV by itself exhibits a low permeation aptitude, this could be significantly enhanced by…

Dentistry and internal medicine: from the focal infection theory to the periodontal medicine concept

Abstract During past decades the relationship between dentistry and internal medicine and especially the concept of the so-called focal infection theory have long been a matter of debate. The pathogenesis of focal diseases has been classically attributed to dental pulp pathologies and periapical infections. Nonetheless, in recent years, their role is being dismissed while increasing interest is being devoted to the possible associations between periodontal infection and systemic diseases. In fact, periodontal pathogens and their products, as well as inflammatory mediators produced in periodontal tissues, might enter the bloodstream, causing systemic effects and/or contributing to systemic d…

Epidemiology, clinical manifestations, risk-reduction and treatment strategies of jaw osteonecrosis in cancer patients exposed to antiresorptive agents

Osteonecrosis of the jaws (ONJ) is an adverse side event of bisphosphonates and denosumab, antiresorptive agents that effectively reduce the incidence of skeletal-related events in patients with metastatic bone cancer and multiple myeloma. Available data suggest that 0–27.5% of individuals exposed to antiresorptive agents can develop ONJ. There is increasing evidence that avoidance of surgical trauma and infection to the jawbones can minimize the risk of ONJ, but there are still a significant number of individuals who develop ONJ in the absence of these risk factors. Bone necrosis is almost irreversible and there is no definitive cure for ONJ with the exclusion, in certain cases, of surgica…

Development of a Multifunctional Bioerodible Nanocomposite Containing Metronidazole and Curcumin to Apply on L-PRF Clot to Promote Tissue Regeneration in Dentistry

Teeth extractions are often followed by alveolar bone reabsorption, although an adequate level of bone is required for reliable rehabilitations by dental implants. Leukocyte and platelet-rich fibrin (L-PRF) has been widely applied in regenerative procedures and with antibiotic and antioxidant agents could play an essential role in hard and soft tissue healing. In this work, a nanocomposite (Sponge-C-MTR) consisting of a hyaluronate-based sponge loaded with metronidazole (MTR) and nanostructured lipid carriers containing curcumin (CUR-NLC) was designed to be wrapped in the L-PRF&trade

Our aim is to report the healing of a critical-size alveolar bone defect treated with a new bone regeneration technique by means of L-PRF and L-PRF blocks. A 45-year-old woman presented a large cystic lesion; the extraction of three teeth, a cyst removal procedure, and bone regeneration procedures with L-PRF and L-PRF blocks were planned. The L-PRF block was prepared by mixing a bone substitute with a piece of L-PRF membrane and liquid fibrinogen. Additionally, after bone healing an implant-based reha…

Orally based diagnosis of celiac disease:current perspective

Celiac disease (CD) is a lifelong immune-mediated disorder caused by the ingestion of wheat gluten in genetically susceptible persons. Most cases of CD are atypical and remain undiagnosed, which exposes the individuals to the risk of life-threatening complications. Serologic endomysial and tissue transglutaminase antibody tests are used to screen at-risk individuals, although a firm diagnosis requires demonstration of characteristic histopathologic findings in the small-intestinal mucosa. A gluten challenge, with a repeat biopsy to demonstrate recurrence of histopathologic changes in the intestinal mucosa after the re-introduction of gluten, is considered for those persons in whom diagnosi…

Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review.

The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnosti…

ORAL HEALTH STATUS AND PERIODONTITIS IN ALZHEIMER'S DISEASE:A POPULATION-BASED, CASE-CONTROL STUDY FROM THE ZABUT AGING PROJECT

Aims. The aetiopathogenesis for Alzheimer's disease (AD) have not been defined, although inflammation within the brain is thought to play a role. Recent data suggest that peripheral infections contribute to the inflammatory state of central nervous system diseases, including cognitive impairment and dementia (1). Periodontitis (PD) is a prevalent, chronic infection involving the tissues supporting the teeth associated with gram negative, anaerobic bacteria capable of promoting local and systemic release of inflammatory mediators. Aim of the present study was to assess the oral health status and the prevalence/severity of PD in incident AD subjects evaluated during a population-based, 10-yea…

Methicillin-resistant staphylococcus aureus (MRSA) osteomyelitis of the mandible: a case report in pediatric patient

Analisi del valore prognostico di uPAR nel carcinoma squamoso del cavo orale.

Halitosis: a stomatological and psychological issue.

It can be stated that halitosis is located on the ridge connecting dentistry, oral medicine, parodontology and psychology. It represents, at the same time, the manifestation of an organic malfunctioning of the oral apparatus, and a problematic element for the individual and his/her relational life. A smelly emanation comes into conflict with the wish to attract, to please, to seduce. The attitudes towards the possibility to suffer from bad breath have two typical opposite expressions, which share the common characteristic that many are bad judges of one's own breath. The dentist, in fact, is frequently involved in the management of patients who believe they have bad breath problems, which i…

Real-time cell analysis by xCELLigence®: a new method for dynamic, quantitative measurement of adhesion and proliferation of cell lines

Objectives. In this study, we report the use of a real-time cell analysis (RTCA) test system, the xCELLigence® RTCA, as efficient tool for a fast growth kinetics analysis of cell lines. This new dynamic real-time monitoring and impedance-based assay allows for a combined measurement of cell adhesion, spreading and proliferation. Methods. We used four representative human OSCC derived cell lines, PE49, HSC2, HSC3 and PE15 cells. The measured impedance values could be correlated to characteristic cell culture behaviours. In parallel, were evaluated proliferation and cell viability of the cell lines by the 3-[4,5-dimethylthizol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. Results. Throug…

Controversies surrounding human papilloma virus infection, head & neck vs oral cancer, implications for prophylaxis and treatment.

Head & Neck Cancer (HNC) represents the sixth most common malignancy worldwide and it is historically linked to well-known behavioural risk factors, i.e., tobacco smoking and/or the alcohol consumption. Recently, substantial evidence has been mounting that Human Papillomavirus (HPV) infection is playing an increasing important role in oral cancer. Because of the attention and clamor surrounding oral HPV infection and related cancers, as well as the use of HPV prophylactic vaccines, in this invited perspective the authors raise some questions and review some controversial issues on HPV infection and its role in HNC, with a particular focus on oral squamous cell carcinoma. The problematic def…

Osteonecrosis of the jaw (ONJ) risk in breast cancer patients after zoledronic acid treatment

The importance of adoption of recommendations for ONJ prevention strategy will notably grow for zoledronic acid in the next future, in view of possible further enlargement of its indications (even with different timing and schedules) in breast cancer patients without bone metastases (such as in adjuvant and neo-adjuvant settings, and in hormonotherapy-induced osteopenia

Medication-related osteonecrosis of the jaw in a cancer patient receiving lenvatinib.

Medication-related osteonecrosis of the jaw (MRONJ) is an adverse drug reaction that affects the mandible and maxilla of patients exposed to bone-targeting agents such as anti-resorptive and anti-angiogenic agents. Several MRONJ cases have been reported after dental extractions in patients under treatment with anti-angiogenic agents, including receptor activator of nuclear factor κB ligand (RANKL) inhibitor, anti-vascular endothelial growth factor (anti-VEGF) monoclonal antibody, mammalian target of rapamycin (mTOR) inhibitors, and tyrosine kinase inhibitors (TKIs). The aim of this article was to describe an original case of lenvatinib-related osteonecrosis of the jaw in a patient affected …

Mesenchymal stem cells derived from inflamed dental pulpal and gingival tissue: a potential application for bone formation

Background Chronic periodontal disease is an infectious disease consisting of prolonged inflammation of the supporting tooth tissue and resulting in bone loss. Guided bone regeneration procedures have become common and safe treatments in dentistry, and in this context dental stem cells would represent the ideal solution as autologous cells. In this study, we verified the ability of dental pulp mesenchymal stem cells (DPSCs) and gingival mesenchymal stem cells (GMSCs) harvested from periodontally affected teeth to produce new mineralized bone tissue in vitro, and compared this to cells from healthy teeth. Methods To characterize DPSCs and GMSCs, we assessed colony-forming assay, immunophenot…

Probiotics Can Cure Oral Aphthous-Like Ulcers in Inflammatory Bowel Disease Patients: A Review of the Literature and a Working Hypothesis

Dysbiosis has been associated with the onset of several chronic autoimmune or inflammatory pathologies (e.g., inflammatory bowel diseases—IBD), because of its primary role in the establishment of a chronic inflammatory process leading to tissue damage. Inflammatory bowel diseases can even involve areas far away from the gut, such as the extraintestinal manifestations involving the oral cavity with the onset of aphthous-like ulcers (ALU). Studies carried out on animal models have shown that intestinal dysbiosis may be related to the development of autoimmune diseases, even if the mechanisms involved are not yet well known. The aim of this paper is to verify the hypothesis that in inflammator…

Site-Coded Oral Squamous Cell Carcinoma Evaluation by Optical Coherence Tomography (OCT): A Descriptive Pilot Study

Optical Coherence Tomography (OCT) is an emerging non-invasive method for oral diagnostics, proving to be a practicable device for epithelial and subepithelial evaluation. The potential validity of OCT in oral cancer assessment has been explored but, to date, there are very few investigations conducted with a systematic comparison between clinical/histological and OCT parameters, especially in strict reference to the anatomical site-codification of the oral mucosa. In this regard, our study performed a two-steps evaluation (in vivo OCT and histological investigations) of suspected OSCCs, progressively recruited, using as references the OCT images of the same site-coded healthy mucosa, to pr…

Unexpected high prevalence of vulvar involvement in Oral Lichen Planus (OLP) females

Adjuvant denosumab in early breast-cancer

We read with interest the D-CARE trial report by Robert Coleman and colleagues1 on the adjuvant administration of denosumab in patients with early-stage breast cancer. Despite the negative results, which pose concerns about high dose denosumab schedules in an adjuvant setting, this large and well- designed trial can provide useful clinical data that are usually difficult to obtain from observational studies, particularly regarding medication- related osteonecrosis of the jaw (MRONJ).

One changing and challenging scenario: the treatment of cancer patients with bone metastases by bisphosphonates and denosumab, the cost-benefit evaluation of different options, and the risk of medication-related osteonecrosis of the jaw (MRONJ)

Antiresorptive drugs (bisphosphonates and denosumab) have become the cornerstone of medical supportive treatment of bone metastases in solid cancer patients. In the beginning, the choice of available antiresorptive agents was limited to bisphosphonates and the treatment options restricted principally to monthly pamidronate and monthly zoledronic acid. Introduction of new antiresorptive therapies (monthly denosumab) and schedules (zoledronic acid every 3 months, upfront or after initial period of monthly infusion) in the last decade increased the range of available options, thus challenging treatment decision making. Direct and indirect costs of very different treatment options are difficult…

A new exciting hypothesis: direct correlation between periodontitis and clinical evolution of COVID-19 patients.

The aim of the present opinion article is to hypothesize a possible correlation between clinical evolution of COVID-19 and a chronic inflammatory disease such as periodontitis. Reviews have been performed about the correlations between COVID-19 and IL-6, COVID-19 and diabetes, diabetes and periodontitis. Several studies discussed the role played by IL-6 in the pathogenetic mechanisms of COVID-19. A recent study found that COVID-19 adult patients with diabetes, without other comorbidities, were at greater risk of numerous diseases COVID related, such as severe pneumonia and excessive uncontrolled inflammatory responses. Besides, serum levels of inflammation-related biomarkers, such as IL-6, …

Oral lichen planus in children: An Italian case series

Oral lichen planus usually occurs in adults; there are no clear data regarding the incidence and the clinical features of oral lichen planus in children. This paper reports clinical findings, treatments, and outcomes of 13 Italian patients with oral lichen planus in childhood diagnosed between 2001 and 2021. The most common finding was keratotic lesions with reticular or papular/plaque-like patterns, confined to the tongue in seven patients. Although oral lichen planus in childhood is rare and the malignant transformation index is unknown, specialists must be aware of its characteristics and oral mucosal lesions must be correctly diagnosed and managed.

Second Opinion System for Intraoral Lesions

In this paper we present the prototype of a teledentistry system to perform the remote diagnosis of oral diseases. It makes use of a particular device called intra-oral (or dental) camera properly designed to shoot video and take pictures of the inner part of the mouth. The intra-oral cameras can be connected via USB to a common PC and they are very cheap, unlike the intra-oral photography kit for DSLR cameras. Usually this kind of devices are used in dentistry studies for local visualization by means of specialized software. The novelty of our system is that the real-time video produced by this device is canalized into a video streming by means of Video LAN client server (VLC) and pictures…

Osteoporosis and bisphosphonates-related osteonecrosis of the jaw: Not just a sporadic coincidence-a multi-centre study

Abstract Introduction Bisphosphonates (BPs) are powerful drugs that inhibit bone metabolism. Adverse side effects are rare but potentially severe such as bisphosphonate-related osteonecrosis of the jaw (BRONJ). To date, research has primarily focused on the development and progression of BRONJ in cancer patients with bone metastasis, who have received high dosages of BPs intravenously. However, a potential dilemma may arise from a far larger cohort, namely the millions of osteoporosis patients on long-term oral BP therapy. Patients and methods This current study assessed 470 cases of BRONJ diagnosed between 2004 and 2008 at eleven different European clinical centres and has resulted in the …

Drug delivery from the oral cavity: focus on a novel mechatronic delivery device

Dental drug delivery systems have been used for a long time, in particular for the local therapy of diseases affecting the oral cavity. Research today concentrates on the design of formulations to increase their retention time. Even today, however, prosthetic devices incorporating drug delivery are rarely used. Mainly, they are focused on prophylaxis and the release of antibacterial agents. However, as buccal delivery, because of its undeniable advantages, has become popular for systemic drug delivery, and prolonged well-controlled release has been identified as beneficial, especially for chronic diseases, a new class of delivery systems is evolving: highly miniaturized computerized deliver…

Metastatic hepatocellular carcinoma of the parotid region without lung metastasis: a case report

Parotid gland metastatic tumours are rare, usually arising from a primary mucosal or cutaneous cancer located in the ipsilateral head and neck region, although metastases from a primary cancer outside the head and neck region are possible. Hepatocellular carcinoma (HCC) rarely metastasizes to the head and neck region and the parotid glands are an even more unusual site. The authors describe the case of an 82-year-old male who presented with a right parotid mass. Percutaneous incisional biopsy with histological and immunohistochemical studies suggested metastatic HCC. Radiological investigations excluded other metastatic lesions. This case illustrates the difficulties that may be encountered…

Behçet's disease in an adolescent patient.

Warthin's tumor distribution within the parotid gland. A feasible etiologic source from lymph nodal tissue.

AIM: Warthin's tumor (WT) is the second commonest parotid gland neoplasm after pleomorphic adenoma (PA). It mainly arises from the lower pole of the superficial parotid lobe (i.e., tail of gland), a site with the greatest distribution of intra-parotid lymph nodes, and its definitive etiopathogenesis is still unclear. The aim of this study was to support the strict topic and etiologic link hypothesised between this tumor and the intraparotid lymph nodes, as being massively present in the tail, by assessing the WT distribution within the parotid gland. METHODS: Seventy-one WTs excised from 64 patients were compared retrospectively with 134 PAs from 133 patients, as controls. In all sample, st…

Osteonecrosis of the jaw related to non-antiresorptive medications: a systematic review

The reporting of osteonecrosis of the jaw (ONJ) related to anticancer agents without known antiresorptive properties (non-antiresorptives), such as antiangiogenics, tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, immune checkpoint inhibitors, and cytotoxic chemotherapy is increasing. To review characteristics of ONJ in cancer patients receiving non-antiresorptives. A systematic review of the literature between 2009 and 2017 was conducted by the Bone Study Group of MASCC/ISOO. Of 6249 articles reviewed and from personal communication, 42 ONJ cases related to non-antiresorptives were identified. No gender predilection was noted. Median age was 60 years and ONJ stage 2 wa…

American Association of Oral and Maxillofacial Surgeons position paper: Bisphosphonate-Related Osteonecrosis of the Jaws-2009 update: the need to refine the BRONJ definition

With reference to the 2009 update of the American Association of Oral and Maxillofacial Surgeons posi- tion paper, Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ), a relevant modification to the previous classification has been made and a new stage (0) added. The latter stage has been defined as “patients with no clinical evidence of necrotic bone, but who present with nonspecific symptoms or clinical and radiographic findings . . .” and the need for various clinical and radiologic aspects in defining this condi- tion was confirmed. .

H3 and H3.3 histone mRNA amounts and ratio in oral squamous cell carcinoma and leukoplakia.

Histone variants (e.g. H3) play an important role in chromatin structure and gene expression regulation of normal cells. Aims of this study were to: (1) estimate H3 and H3.3 histone mRNA expressions and their ratio in oral squamous cell carcinoma (OSCC) and oral leukoplakia (OL); (2) investigate whether H3 and H3.3 variants could play a role in the pathogenesis of OSCC and OL, also conditionally to HPV infection, age, gender, and main habits (tobacco smoking and alcohol drinking) in human beings studied. Twenty-three cases of OSCC and 20 cases of OL were examined in lesion site (LS) and juxtaposed clinically undamaged site (JUS) by RT-PCR for H3 and H3.3 histone mRNA; 13 healthy oral mucosa…

Osteonecrosis of jaw (onj): impact of italian patients, and role of italian physicians, dentists, and researchers in the growing evidence of a “new” disease

Purpose: Osteonecrosis of jaw (ONJ) is an uncommon but severe complication observed mostly in patients treated with bisphosphonates (BPs) for bone metastases, myeloma, osteoporosis (so called BRONJ, Bisphosphonate-Related Osteonecrosis of Jaw), but also with other drugs (bevacizumab, sunitinib, denosumab). The number of cases observed in Italy appears high in comparison with other countries and we present a review of several aspects of ONJ in Italy and the role of Italian health professionals and researchers on increasing knowledge and adequate reporting of ONJ phenomenon; Methods: Literature review about osteonecrosis of jaw (ONJ) with selection of Italian authors and publications, on year…

BRONJ in patients with rheumatoid arthritis: A multicenter case series

Objective: Osteonecrosis of the jaw (ONJ) is a potentially severe adverse effect of various medications (bisphosphonates, anti-resorptive, and anti-angiogenic drugs). ONJ pathogenesis is still unclear although some risk factors have been recognized. Of these, rheumatoid arthritis (RA) has been hypothesized as a potential risk factor for developing ONJ. This observational study will describe a multicenter case series of patients affected with RA and ONJ, and it will attempt to evaluate the association between features of ONJ and pharmacological, systemic, and site variables. Methods: Demographic, pharmacological, and clinical data from 18 RA patients with ONJ were collected and registered fr…

Osteonecrosis of the Jaw in Myeloma Patients Receiving Denosumab or Zoledronic Acid. A Commentary of the Pivotal Trial by Raje et al. Published on Lancet Oncology.

The recent randomized trial, published by Raje et al., on Lancet Oncology is potentially practice changing. It proposes that denosumab is a valid alternative to zoledronic acid in the treatment of myeloma patients. However, several points need further data and more details, such as information on incidence, diagnosis, and follow-up of osteonecrosis of the jaw (ONJ) cases, observed among treated patients. Adopted definition to adjudicate ONJ cases, type of registration of potential ONJ cases, length of observation are possible causes of potential underestimation of ONJ incidence in their study. Future updated evaluations with longer follow-up, and including actuarial estimation, are required…

Nonexposed Variant of Bisphosphonate-associated Osteonecrosis of the Jaw: A Case Series

Abstract Purpose To report a case series of patients with the nonexposed variant of bisphosphonate-associated osteonecrosis of the jaw—a form of jaw osteonecrosis that does not manifest with necrotic bone exposure/mucosal fenestration. Methods Among 332 individuals referred to 5 clinical centers in Europe because of development of jawbone abnormalities after or during exposure to bisphosphonates, we identified a total of 96 patients who presented with the nonexposed variant of osteonecrosis. Relevant data were obtained via clinical notes; radiological investigations; patients' history, and referral letters. Results The most common clinical feature of nonexposed osteonecrosis was jaw bone pa…

Long-standing oral ulcers: proposal for a new `S-C-D classification system’

Persistent oral ulcers and erosions can be the final common manifestation, sometimes clinically indistinguishable, of a diverse spectrum of conditions ranging from traumatic lesions, infectious diseases, systemic and local immune-mediated lesions up to neoplasms. The process of making correct diagnosis for persistent oral ulcers still represents a challenge to clinicians. Major diagnostic criteria should include the clinical appearance of both ulcer and surrounding non-ulcerated mucosa, together with the evaluation of associated signs and symptoms, such as: number (single or multiple), shape, severity of the ulcer(s), conditions of remaining mucosa (white, red or with vesiculo-bullous lesio…

Gingivitis

Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing ulcerative gingivitis (NUG) is a more serious condition that is mainly found in developing countries associated with people with severe malnutrition or HIV/AIDS with low CD4 T-cell counts.

Epidemiology of desquamative gingivitis: evaluation of 125 patients and review of the literature

Background  Desquamative gingivitis (DG) is a descriptive term used to indicate epithelial desquamation, erythema, erosions, and/or vesiculobullous lesions of the gingiva. DG is commonly associated with several mucocutaneous disorders and systemic conditions that may carry a poor prognosis and high morbidity; however, there are no clear data concerning the frequency of these disease associations. Methods  We investigated the epidemiologic features of DG in 125 patients and compared our findings with information from a literature review. Results  In our series, 88% of patients with DG had one of the following three disorders: oral lichen planus (OLP), mucous membrane pemphigoid (MMP), or pem…

Pathophysiology of age-related diseases

Abstract A Symposium regarding the Pathophysiology of Successful and Unsuccessful Ageing was held in Palermo, Italy on 7-8 April 2009. Three lectures from that Symposium by G. Campisi, L. Ginaldi and F. Licastro are here summarized. Ageing is a complex process which negatively impacts on the development of various bodily systems and its ability to function. A long life in a healthy, vigorous, youthful body has always been one of humanity's greatest dreams. Thus, a better understanding of the pathophysiology of age-related diseases is urgently required to improve our understanding of maintaining good health in the elderly and to program possible therapeutic intervention.

Human Papillomavirus (HPV) Detection in Keratotic Variants of Oral Lichen Planus: Negative Results in a Preliminary Open Study

Background During the last few decades, several researches have been identified HPV genomic sequences in Head Neck Squamous Cell Carcinomas (HNSCC) and in Oral Potentially Malignant Disorders (OPMD) hypothesizing a possible viral etiological role. However, the reported prevalence of HPV-DNA (varying from 0% to 100%) in these lesions result still very discordant. Objective Human papillomavirus (HPV) infection in Oral Lichen Planus (OLP) has been largely investigated but not so extensively with respect to its morphological/histopathological features. The possible influence of hyper-keratosis/parakeratosis in HPV detection for keratotic variants of OLP is here proposed and investigated. Materi…

New paradigms for dental prevention of medication related osteonecrosis of jaws (MRONJ)

ONJ-Prevention of local osteonecrosis risk factors should be planned before and during the intake of associated drugs, according to new schedules. Secondary prevention requires a careful clinical oral examination, but also first level X-ray examinations and, when necessary, second level (CT) too. Three main risk factors of ostonecrosis of the jaws (ONJ) are recognised: (i) the type of ONJ-related medications: antiresorptive (e.g., Bisphosphonates, Denosumab) and antiangiogenic drugs (e.g., Bevacizumab, Sunitinib); (ii) the category of patient at MRONJ risk: cancer versus non-cancer patient; (iii) the typologies and timing of dental treatments (e.g., before, during, or after the drug adminis…

Papillary oncocytic cystoadenoma arising from the tongue:a case report

Cleavage of desmoglein 3 can explain its depletion from keratinocytes in pemphigus vulgaris.

We have previously demonstrated that serum of patients with pemphigus vulgaris induces reduction of desmoglein 3 (Dsg3) half-life in keratinocytes (FEBS Lett 2006: 580: 3276). This phenomenon seems to occur as a consequence of the progressive depletion of Dsg3 from desmosomes. Here we reported that reduction of full-length Dsg3 may be due to its progressive cleavage, leading to the formation of two fragmentation products with apparent molecular masses of about 60 kDa (fragment 1) and 70 kDa (fragment 2), as revealed by Western blotting. Unexpectedly, analysis of fragmentation pattern suggested cleavage to occur intracellularly. Consistently, fragment 1 was shed and localized within the cyto…

MRONJ in breast cancer patients under bone modifying agents for cancer treatment-induced bone loss (CTIBL): a multi-hospital-based case series

Abstract Background Cancer treatment-induced bone loss (CTIBL) is the most common adverse event experienced by patients affected by breast cancer (BC) patients, without bone metastases. Bone modifying agents (BMAs) therapy is prescribed for the prevention of CTIBL, but it exposes patients to the risk of MRONJ. Methods This multicentre hospital-based retrospective study included consecutive non-metastatic BC patients affected by MRONJ related to exposure to low-dose BMAs for CTIBL prevention. Patients’ data were retrospectively collected from the clinical charts of seven recruiting Italian centres. Results MRONJ lesions were found in fifteen females (mean age 67.5 years), mainly in the mandi…

HPV in oral squamous cell carcinoma vs head and neck squamous cell carcinoma biopsies: a meta-analysis (1988-2007).

Abstract INTRODUCTION: In the literature, there exists a wide range of human papillomavirus (HPV) DNA prevalence for head and neck squamous cell carcinoma (HNSCC), especially in relation to methods of viral detection and the lesion site. We estimated the pooled prevalence of HPV DNA in biopsies of HNSCC generically grouped versus oral squamous cell carcinoma (OSCC) in relation to the method of viral DNA detection, with the primary end point of verifying if these two variables (specification of tumour site and method of HPV DNA identification) influence the datum on HPV assay. METHODS: By means of MEDLINE/PubMED/Ovid databases, we selected studies examining paraffin-embedded (PE) biopsies of…

Oral HPV Infection: Current Strategies for Prevention and Therapy

Infection with High Risk (HR) Human Papillomaviruses (HPVs) is the main aetiological agent of Cervical Squamous Cell Carcinoma (CSCC) and also associated in a subgroup of other neoplasms, including Oropharyngeal Squamous cell Carcinoma (OPSCC). HPV infection, in genital as in oral mucosa, can also be subclinical or associated with benign proliferative lesions (common warts, condylomas, papillomas) caused mostly by infection with Low Risk (LR)-HPVs. In the last decades, extensive research has resulted in growing knowledge on HPV biology and specifically viral life cycle, biochemical properties of viral proteins and their interaction with the host proteins leading to potential new targets of …

Optical coherence tomography as a simple and non invasive tool for the diagnosis of oral disease: a case report

Introduction. Optical Coherence Tomography (OCT) is a new biomedical imaging modality that provides high reso- lution cross-sectional images of tissue. Conceptually, it has been compared with ultrasound scanning but it uses in- frared light and records reflections below the surface to produce a cross-sectional architectural image of the tissue. OCT has been applied in ophthalmology and recently in dermatology; several studies have shown the validity of the use of OCT in ex vivo oral lesions but, to date, it does not exist a bank of normative and pathological OCT data of the oral tissues to consent identification of cellular structures of normal and pathological processes. We report a case o…

Osteonecrosis of jaw beyond antiresorptive (bone-targeted) agents: new horizons in oncology

Introduction: Osteonecrosis of the jaw (ONJ) is a clinically important, potentially painful and debilitating condition, which can affect the quality of life of cancer patients. Since 2003, ONJ appeared as a Bisphosphonate(BP)-related class effect, and the term Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ) was widespread. Areas Covered: Under discussion in this review is the fact that ONJ cases have been reported after treatment including antiangiogenic agents and other “targeted therapy”, with and without BPs. Consequently, the comprehensive term Medication-Related Osteonecrosis of the Jaw (MRONJ) has been introduced. The clinical aspects and the prognosis of ONJ associated with t…

Surgery-triggered and non surgery-triggered Bisphosphonate-related Osteonecrosis of the Jaws (BRONJ): A retrospective analysis of 567 cases in an Italian multicenter study

Invasive local procedures are often reported in clinical history of patients suffering from Bisphosphonates-Related Osteonecrosis of the Jaws (BRONJ) but over 40% of spontaneous forms have been also described in literature. We compared age, gender, underlying bone disorders, bisphosphonate therapy, clinical features and surgical outcome of 205 cases (36.2%) of BRONJ non surgery-triggered (group 1) with 362 (63.8%) cases of surgery-triggered forms (group 2). Differences between group 1 and 2 were analysed using Mann-Whitney U and χ2 tests. Statistical analysis was performed using STATA 8.

Osteonecrosis of the Jaw in Patients With Metastatic Renal Cell Cancer Treated With Bisphosphonates and Targeted Agents: Results of an Italian Multicenter Study and Review of the Literature.

Osteonecrosis of the jaw (ONJ) associated with the use of bisphosphonates has been rarely reported in metastatic renal cell cancer (RCC) patients. Since the introduction of combined therapies consisting of nitrogen-containing bisphosphonates (NBPs) and targeted agents, an increasing number of RCC patients were reported to develop ONJ, suggesting that therapeutic angiogenesis suppression might increase the risk of ONJ in NBPs users. We performed a multicenter retrospective study and reviewed literature data to assess the occurrence and to investigate the nature of ONJ in RCC patients taking NBPs and targeted agents. Nine Italian Centers contributed to the data collection. Patients with expos…

Platelet-Rich Plasma (PRP) in Dental Extraction of Patients at Risk of Bisphosphonate-Related Osteonecrosis of the Jaws: A Two-Year Longitudinal Study

Squamous Cell Tumors Recruit γδ T Cells Producing either IL17 or IFNγ Depending on the Tumor Stage

Abstract The identification of reciprocal interactions between tumor-infiltrating immune cells and the microenviroment may help us understand mechanisms of tumor growth inhibition or progression. We have assessed the frequencies of tumor-infiltrating and circulating γδ T cells and regulatory T cells (Treg) from 47 patients with squamous cell carcinoma (SCC), to determine if they correlated with progression or survival. Vδ1 T cells infiltrated SSC tissue to a greater extent than normal skin, but SCC patients and healthy subjects had similar amounts circulating. However, Vδ2 T cells were present at higher frequencies in circulation than in the tissue of either cancer patients or healthy donor…

Protein Cargo of Salivary Small Extracellular Vesicles as Potential Functional Signature of Oral Squamous Cell Carcinoma

The early diagnosis of oral squamous cell carcinoma (OSCC) is still an investigative challenge. Saliva has been proposed as an ideal diagnostic medium for biomarker detection by mean of liquid biopsy technique. The aim of this pilot study was to apply proteomic and bioinformatic strategies to determine the potential use of saliva small extracellular vesicles (S/SEVs) as a potential tumor biomarker source. Among the twenty-three enrolled patients, 5 were free from diseases (OSCC_FREE), 6 were with OSCC without lymph node metastasis (OSCC_NLNM), and 12 were with OSCC and lymph node metastasis (OSCC_LNM). The S/SEVs from patients of each group were pooled and properly characterized before perf…

Necrotizing fasciitis of the face: A life-threatening condition

Necrotizing fasciitis (NF) is a highly aggressive infectious process, polymicrobial in nature, involving soft tissues with a high risk of rapid spread through superficial and deep fascial planes and muscular layers. Cervical NF is quite rare, is mostly of odontogenic origin, and may be complicated by descendant mediastinitis with a very high mortality rate. Systemic conditions impairing the patient's immune competence, such as diabetes, may play a predisposing role. An effective treatment strategy includes prompt diagnosis (clinical findings, local microbiological tests, blood culture and, if deemed necessary, histopathology), broad-spectrum antibiotic therapy as early as possible which sho…

Human buccal mucosa as an innovative site of drug delivery.

The authors review the ultra-structural aspects and permeability features of normal human oral mucosa, after having recently tested and used it as a new site of systemic drug delivery. The pertinent scientific literature from 1975 through 2009 has been analysed and discussed. Buccal epithelium is a relatively permeable, robust non-keratinized tissue and blood vessels drain directly into the jugular vein; due to its particular features, it has been of increasing interest to researchers as an alternative site of drug administration. The review describes the structure and function of the buccal mucosa, the rationale for transbuccal drug delivery and the main transmucosal drug delivery systems.…

The dental management of patients at risk of medication-related osteonecrosis of the jaw: New paradigm of primary prevention

Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse reaction of antiresorptive and antiangiogenic agents; it is a potentially painful and debilitating condition that can considerably affect the quality of life of patients. Furthermore, even if its epidemiology and pathogenesis have still not been fully clarified, several risk factors related to MRONJ have been recognized in prevention protocols. Three main risk factors are as follows: (i) the type of ONJ-related medications: antiresorptive (e.g., Bisphosphonates, Denosumab) and antiangiogenic drugs (e.g., Bevacizumab, Sunitinib); (ii) the category of patient at MRONJ risk: cancer versus non-cancer patient; (iii) the typ…

Human Papillomavirus Infection: A Risk Factor for Oral and Oropharyngeal Cancers

A wide range of human papillomavirus (HPV) prevalence data is now available for head and neck squamous cell carcinomas (HNSCCs), especially for those cancers originating from the epithelial lining of the upper aero-digestive tract (UADT) (i.e., the pharynx, the larynx, and the oral cavity). There is strong evidence that supports HPV as an etiological cause of head and neck carcinogenesis particularly for distinct oropharyngeal subsites. A specific molecular, histopathological, clinical, and prognostic profile is intimately connected with HPV infection. While the role of HPV in oropharyngeal carcinogenesis is firmly acknowledged, its role in oral cancer is currently being debated. Several re…

Methionine synthase reductase (MTRR) A66G polymorphism is not related to plasma homocysteine concentration and the risk for vascular disease.

Epidemiological evidence has revealed that hyperhomocysteinemia increases the risk for vascular disease. Methionine Synthase Reductase (MTRR) is one of several key enzymes in the homocysteine metabolic pathway and its mutant forms have been implicated in abnormal homocysteine accumulation. In this study, we determined total plasma homocysteine levels and MTRR A66G polymorphism in 114 patients with vascular disease: 58 patients with deep-vein thrombosis, 56 patients with arterial thrombosis, and 95 healthy subjects from the Sicilian population. Our data confirmed that, as already reported, moderately elevated t-Hcy levels are correlated with an increased risk of vascular disease. In our stud…

In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit&reg

Painful oral aphthous-like lesions in patient with kidney cancer after target therapy and bisphosphonate administration: a case report of adverse drug reaction.

Aim. Tyrosine kinase inhibitors (TKIs) targeting tu- mor angiogenesis and mammalian target of rapamycin inhibitors (mTOR) are indicated for the management of several cancer types, as for renal cell carcinoma (RCC). Oral ulcerations are reported as common adverse drug reactions of mTOR inhibitors and are currently classified as mTOR inhibitor associated stomatitis (mIAS). Interestingly, these lesions appear as aphthous-like stoma- titis rather than the mucositis seen with chemotherapy agent. Case report. A 49 years old male patient underwent to the left radical nephrectomy in May 2014 for clear RCC. From July to October 2014 he was treated with Pazopanib, a tyrosine kinase inhibitor. In Dece…

Beta-catenin and surviving expression in keratocystic odontogenic tumor (KCOT). A comparative immunohistochemical study in primary, recurrent and nevoid basal cell carcinoma syndrome (NBCCS)-associated lesions

Aim: To determine the epithelial expression of ß-catenin and survivin in sporadic (primary, and recurrent) and nevoid basal cell carcinoma syndrome (NBCCS) keratocystic odontogenic tumour (KCOT) in order to assess activation of the ß-catenin pathway and evidence of apoptotic inhibition, processes that may contribute to the known differences in their biological behaviour. Materials and Methods: Sections from 40 cases of KCOT (19 sporadic/primary; 9 sporadic/recurrent and 12 NBCCS-associated) were immunohistochemically stained for ß-catenin and survivin. The extent and intensity of immunoreactivity within the lining epithelium was assessed, using semi-quantitative scales, independently by two…

Current Controversies in Classification, Management, and Prevention of Bisphosphonate-Related Osteonecrosis of the Jaw

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a serious complication associated with oral and intravenous bisphosphonate therapy that adversely affects the quality of life, producing significant morbidity. Since the first description of bone necrosis in patients receiving bisphosphonate therapy in 2003 [1], hundreds of studies were published about this topic and various national and international medical societies have published protocols and guidelines. Nevertheless, there are still many controversies regarding the classification, management, and prevention of BRONJ. Even the definition of BRONJ is still debated and changed with the progress of knowledge and experience. Accord…

Chemopreventive and Anticancer Role of Resveratrol against Oral Squamous Cell Carcinoma

Oral squamous cell carcinoma (OSCC) is one of the most prevailing and aggressive head and neck cancers, featuring high morbidity and mortality. The available conventional treatments suffer from several adverse effects and are often inefficient in terms of their survival rates. Thus, seeking novel therapeutic agents and adjuvants is of the utmost importance for modern society. Natural polyphenolic compounds have recently emerged as promising chemopreventive and anticancer agents. Specifically, the natural compound resveratrol (RSV) has recently gained momentum for this purpose. RSV is useful for treating OSCC due to its antiproliferative, antimetastatic, and proapoptotic effects. Additionall…

Aging and Oral Health: Effects in Hard and Soft Tissues

Changing demographics, including an increase in life expectancy and the growing numbers of elderly has recently focused attention on the need for geriatric dental care. Ageing affects oral tissues in addition to other parts of the human body, and oral health (including oral mucosa, lips, teeth and associated structures, and their functional activity) is an integral component of general health; indeed, oral disease can cause pain, difficulty in speaking, mastication, swallowing, maintaining a balanced diet, not to mention aesthetical considerations and facial alterations leading to anxiety and depression. The World Health Organization recommends the adoption of certain strategies for improvi…

Osteoporosis, jawbones and periodontal disease

The association between osteoporosis and jawbones remains an argument of debate. Both osteoporosis and periodontal diseases are bone resorptive diseases; it has been hypothesized that osteoporosis could be a risk factor for the progression of periodontal disease and vice versa. Hypothetical models linking the two conditions exist: in particular, it is supposed that the osteoporosis-related bone mass density reduction may accelerate alveolar bone resorption caused by periodontitis, resulting in a facilitated periodontal bacteria invasion. Invading bacteria, in turn, may alter the normal homeostasis of bone tissue, increasing osteoclastic activity and reducing local and systemic bone density …

A novel mutation of gene CBFA1/RUNX2 in cleidocranial dysplasia.

Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia characterised by abnormal clavicles, patent sutures and fontanelles, supernumerary teeth, short stature, and a variety of other skeletal changes. The disease gene is CBFA1/RUNX2, which is mapped to chromosome 6p21. Inactivation of the CBFA1/RUNX2 gene by mutations is involved in the skeletal defects that occur in patients with CCD. CBFA1/RUNX2 controls the differentiation of precursor cells into osteoblasts and is essential for membranous as well as endochondral bone formation. In this study of a 14-yr-old boy with typical CCD phenotype, the authors found a novel CBFA1/RUNX2 gene mutation. All of the amplified segment…

Possible link between Hashimoto's thyroiditis and oral lichen planus: a novel association found

Objectives: Hashimoto's thyroiditis as well as lichen planus has been associated to a number of disorders, generally of auto-immune origin. A novel possible association between oral lichen planus (OLP) and Hashimoto's thyroiditis (HT) is here proposed on the basis of a cross-sectional survey. Materials and methods: One hundred and five unrelated OLP patients were considered. Diagnosis of HT was based on positive serum anti-TPO, anti-Tg, TSH levels and the typical ultrasound pattern of the thyroid gland. Results: In the present survey, the prevalence of HT in the OLP group was 14. 3 % whereas the prevalence of HT-related hypothyroidism in the general population was reported to be equal to 1 …

Gingivitis

Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing ulcerative gingivitis (NUG) is a more serious condition that is mainly found in developing countries associated with people with severe malnutrition or HIV/AIDS with low CD4 T-cell counts.

Histological findings of osteonecrosis spotted prior to tooth extractions. Should we consider tooth extraction still the main trigger event?

Osteonecrosis of the jaw (ONJ) is an adverse drug reaction described as the progressive destruction and death of bone that affects the mandible and maxilla of patients exposed to the treatment with medications known to increase the risk of disease, in the absence of a previous radiation treatment. Tooth extraction often precedes the manifestation of ONJ; indeed, it is sometimes called trigger event and it have also been considered as risk factors for the onset of ONJ. As a consequence, some of the guidelines recommend avoiding tooth extractions in patients at risk of ONJ; however, a growing body of evidence indicates that dental/periodontal infection prior to extraction, rather than dental …

Topical therapies for oral lichen planus management and their efficacy: a narrative review.

Oral Lichen Planus (OLP) is a chronic inflammatory condition implicating T cell-mediated cytotoxicity, and involving oral mucosal surfaces. Several therapeutic regimens have been evaluated to treat OLP and pain related, but often without high level of evidence. Topical formulations are the favourite for the majority of cases; bioadhesive formulations have been considered very useful and practical for local drug delivery in oral mucosa, due to the increased residence time on the oral mucosa of the dosage forms and better therapeutic efficacy. In this narrative review, authors try to illustrate the current topical managements for OLP from the accessible literature on this topic. Steroids are …

Oral squamous cell carcinoma mimicking osteonecrosis of the jaw: a case report

Osteonecrosis of the jaw (ONJ) is a well-known adverse drug reaction to bisphosphonate (BP) treatment. ONJ diagnosis is usually based on the patient’s medical/medication histories and on the clinical/radiological features of necrotic bone (frequently exposed). Furthermore, in case of mandibular involvement, patients may present pain and/or hypesthesia of the inferior alveolar nerve. There are no pathognomonic clinical and radiological signs of ONJ, and in doubtful cases, the histologic examination is recommended. We report a case of a woman attending to our sector of Oral Medicine (AOUP “P. Giaccone” Palermo, Italy) with a mandibular bone exposure after implants loss and a medical history o…

US7 Oral mucosal ulcerations

Oral mucosal ulcer represents a localized loss of the lining epithelium and sometimes also of the subjacent connective tissue. It could be persistent or recurrent and also single or multiple. As regards those persistent a large variety of etiologic factors have been suggested: this kind of ulcers could be a sign of a localised direct reaction to any physical/chemical injury or due to a drug-related reaction (e.g. by chemotherapy). Mucosal ulceration could also occur in a multiplicity of diseases such as neoplasia, infection, immune-mediated disease or as sign of systemic diseases (e.g. of blood, skin or gastrointestinal tract). A correct diagnosis needs to collect as carefully as possible s…

Mucoadhesive polymers for oral transmucosal drug delivery: a review.

The oral mucosa offers an interesting site for the application of dosage forms that release drugs within/throughout the oral mucosa, by assuring a high drug bioavailability for topic and systemic effects. However, the relative permeability of the oral mucosa and the washing effect related to the oral fluids and mechanical stresses must be considered in the formulation of oral dosage forms. Since a sustained drug release can be guaranteed only if dosage forms remain in contact with the oral site of absorption/application for a prolonged time, the development of mucoadhesive dosage forms is mandatory. The mucoadhesion is a complex phenomenon and the mucoadhesive bond consists of two different…

Immune-Mediated Desquamative Gingivitis and Optical Coherence Tomography Diagnostic Patterns: Clinical Implication from a Systematic Review

Desquamative Gingivitis (DG) comprises heterogeneous clinical manifestations of numerous immune-mediated muco-cutaneous diseases. Optical Coherence Tomography (OCT) has been proposed as a valuable diagnostic support even if, to date, there are no standardized OCT-diagnostic patterns applicable to DGs. A systematic review was performed to detect existing data on in vivo OCT diagnostic patterns of the most common immune-mediated DGs (i.e., pemphigus vulgaris, mucous membrane pemphigoid and oral lichen planus). It has been found that OCT exhibits specific patterns that address the diagnosis of DG by pemphigus vulgaris (i.e., intraepithelial unilocular blister, reduced epithelial thickness, pre…

Release of naltrexone on buccal mucosa: Permeation studies, histological aspects and matrix system design

Transbuccal drug delivery has got several well-known advantages especially with respect to peroral way. Since a major limitation in buccal drug delivery could be the low permeability of the epithelium, the aptitude of NLX to penetrate the mucosal barrier was assessed. Ex vivo permeation across porcine buccal mucosa 800 microm thick was investigated using Franz type diffusion cells and compared with in vitro data previously obtained by reconstituted human oral epithelium 100 microm thick. Both fluxes (Js) and permeability coefficients (K(p)) are in accordance, using either buffer solution simulating saliva or natural human saliva. Permeation was evaluated also in presence of chemical enhance…

COVID-19 and periodontitis: reflecting on a possible association

AbstractRecent studies have demonstrated a relationship between the severe clinical course of COVID-19 and other chronic diseases such as: cardiovascular disease, hypertension, diabetes mellitus, obesity and chronic renal disease. It may be possible to extend this association to a common and chronic oral disease in adults: periodontitis. Alternatively, the latter could be simply related to the systemic chronic diseases cited above, as already observed in the non-COVID-19 literature. In order to provide an overview and their opinion, the authors in this perspective article will report and discuss the most recent references of interest relating to COVID-19 and periodontitis pathophysiology.

Aim of this study was to investigate survivin expression and HPV presence in oral premalignant lesions and oral carcinoma. 47 samples of oral tissue including 11 squamous cell carcinomas (OSCC), 16 oral leukoplakias (OL) and 20 normal oral mucosa specimens, after investigation of HPV presence by nested PCR (consensus MY/GP primers) and viral genotype identification by direct seque…

Medium-Term Culture of Primary Oral Squamous Cell Carcinoma in a Three- Dimensional Model: Effects on Cell Survival Following Topical 5-Fluororacile Delivery by Drug-Loaded Matrix Tablets

Since the activity of several conventional anticancer drugs is restricted by resistance mechanisms and dose-limiting side-effects, the design of formulations for local application on malignant lesions seems to be an efficient and promising drug delivery approach. In this study, the effect of locally applied 5-FU on cell death was evaluated both in a SCC4/HEK001 model and in a newly proposed 3D outgrowth model of oral squamous cell carcinoma (OSCC). Initially, the optimal drug dose was established by delivery of solutions containing different amounts of 5-FU. The solution containing 1% (w/v) of 5-FU resulted effective in inducing cell death with complete eradication of cell colonies. Buccal …

Halitosis: could it be more than mere bad breath?

Halitosis is a generic term used to describe unpleasant odor emanating from the mouth air and breath, independent of the source where the odor substances originate. It affects between 50 and 65% of the population, but despite its frequency, this problem is often unaccepted and declared as taboo. Ninety percent of patients suffering from halitosis have oral causes: a small, but important percentage, of oral malodor cases have an extra-oral etiology, very often falling into the category of "blood-borne halitosis". Several systemic diseases have been found to provoke malodor or to be a cofactor; bad breath may be an early sign of a serious local or systemic condition. A psychogenic halitosis a…

Platelet-rich plasma (PRP) in dental and oral surgery: from the wound healing to bone regeneration

Platelet-rich plasma (PRP) is a new approach to tissue regeneration and it is becoming a valuable adjunct to promote healing in many procedures in dental and oral surgery, especially in aging patients. PRP derives from the centrifugation of the patient's own blood and it contains growth factors that influence wound healing, thereby playing an important role in tissue repairing mechanisms. The use of PRP in surgical practice could have beneficial outcomes, reducing bleeding and enhancing soft tissue healing and bone regeneration. Studies conducted on humans have yielded promising results regarding the application of PRP to many dental and oral surgical procedures (i.e. tooth extractions, per…

Patients and methods: Eight oral lichen planus (OLP) and four mucous membrane pemphigoid (MMP) patients were examined. Periodontal measurements (performed at six sites per tooth on all teeth) included probing depth (PD), gingival recession (REC), clinical attachment loss (CAL) and full mouth plaque (FMPS) and bleeding (FMBS) scores; the presence and the exact location (site by site) of DG lesions were carefully recorded. Sub-gingiva…

Conservative Surgical Treatment of Bisphosphonate-Related Osteonecrosis of the Jaw with Er,Cr:YSGG Laser and Platelet-Rich Plasma: A Longitudinal Study

Introduction. The management of bisphosphonate-related osteonecrosis of the jaw (BRONJ), with no evidence-based guidelines, remains controversial. We aimed to evaluate the efficiency of a conservative surgical treatment combining Er,Cr:YSGG laser and platelet-rich plasma (PRP) for the treatment of BRONJ in cancer patients. Methods. We performed a longitudinal cohort study. Inclusion criteria were (1) age ≥ 18 years; (2) cancer diagnosis; (3) treatment with NBP because of the underlying cancer. Results. We consecutively recruited ten patients diagnosed with BRONJ in stage I or II. These patients underwent a surgical laser-assisted therapy together with autologous PRP. At the latest follow-up…

RESTITUTIO AD INTEGRUM IN A CASE OF ONJ RELATED TO BEVACIZUMAB

Aim. Bevacizumab is a humanized recombinant monoclonal antibody that blocks vascular endothelial growth factor (VEGF). The activity of VEGF is the ability to promote the vascular endothelial cells proliferation inducing the formation of new blood vessels. Bevacizumab is used in the treatment of selected advanced colon, lung, renal and central nervous system tumours and plays a developing role in the management of breast and ovarian cancers. It is also injected intraocularly for treatment of macular degeneration. Recently, bevacizumab has been reported as responsible of drug-related osteonecrosis of the jaw (ONJ), showing a histological pattern similar to bisphosphonate-related ONJ. Moreover…
