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

2007

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

2006

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.

Effect of desquamative gingivitis on periodontal status: a pilot study

2010

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 …

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

2015

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…

Legal liability in bisphosphonate-related osteonecrosis of the jaw

2014

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…

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

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

2020

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…

Number III Mucous membrane pemphigoid

2005

Mucous membrane pemphigoid (MMP) is a sub-epithelial vesiculobullous disorder. It is now quite evident that a number of sub-epithelial vesiculobullous disorders may produce similar clinical pictures, and also that a range of variants of MMP exist, with antibodies directed against various hemidesmosomal components or components of the epithelial basement membrane. The term immune-mediated sub-epithelial blistering diseases (IMSEBD) has therefore been used. Immunological differences may account for the significant differences in their clinical presentation and responses to therapy, but unfortunately data on this are few. The diagnosis and management of IMSEBD on clinical grounds alone is impo…

Expression of salivary biomarkers in patients with oral mucositis: evaluation by SELDI-TOF/MS.

2016

Objective: This study aims to evaluate changes in proteomic salivary profile of patients with oral mucositis after adjuvant cancer treatments. Materials and Methods: Samples were collected from patients after adjuvant cancer therapies, and were analyzed by means of SELDI/TOF. Patients were separated in two groups: patients affected by mucositis (MUCOSITIS) and patient without mucositis (NO MUCOSITIS). All patients were divided in function of the anticancer treatment: patients who had radiotherapy (MUCOSITIS RADIO), had not radiotherapy (MUCOSITIS NO RADIO), had chemotherapy (MUCOSITIS CHEMO), and those who had not chemotherapy (MUCOSITIS NO CHEMO).

Adverse drug reactions in the oral cavity

2012

Several drugs may have a number of adverse reactions (ADRs) involving the oro-facial region. The dose of the drug and the time required for the reaction to take place are relevant parameters; nonetheless, ADRs mechanisms are not always known and ADRs are not always predictable since aspects other than drug pharmacodynamics and/or pharmacokinetics, as well as various interacting variables contribute to the final outcome. All tissues and many functions of the oral cavity can be affected. In particular, salivary function is fre- quently involved and hypo-salivation is the main manifestation; several mucosal lesions with different morphology (ulcerations, vesiculo- bullous lesions, white lesion…

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

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

2011

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…

2012

Abstract Background Recent emerging evidences identify Human Papillomavirus (HPV) related Head and Neck squamous cell carcinomas (HN-SCCs) as a separate subgroup among Head and Neck Cancers with different epidemiology, histopathological characteristics, therapeutic response to chemo-radiation treatment and clinical outcome. However, there is not a worldwide consensus on the methods to be used in clinical practice. The endpoint of this study was to demonstrate the reliability of a triple method which combines evaluation of: 1. p16 protein expression by immunohistochemistry (p16-IHC); 2. HPV-DNA genotyping by consensus HPV-DNA PCR methods (Consensus PCR); and 3 viral integration into the host…

Reciprocal altered expression of E-cadherin and P-cadherin in mucous membrane pemphigoid.

2011

E- and P- cadherins are involved in the selective adhesion of epidermal cells. To gain insight into the role of cadherins on the acantholysis of keratinocytes and further investigate the pathogenesis of Mucous Membrane Pemphigoid, we examined the expression of P-cadherin and E-cadherin, in normal human oral mucosa, lesional and peri-lesional mucosa in MMP. Twenty-nine samples from paraffin-embedded specimens of MMP were used for the study. Five specimens of healthy oral mucosa were evaluated as control group. To evaluate the E- and P-Cadherin expression, a mean percentage of positive cells was determined from the percentage of positive cells derived from the analysis of 100 cells in ten ra…

After scoring the level of infection risk, safety procedures, advice and personal protective equipment (PPE) are recommended for the dental team in each dental practice. Methods The authors of this research analysed 42 common dental procedures on the basis of known transmission risks. In increasing order, many consider the parameters leading to different risk scores for the dental team and patients for each procedure to be: direct contact with saliva (score 1), direct contact with blood (score 2), production of low levels of spray/aer…

Oral dysphagia. An unique symptom for a wide spectrum of diseases

2009

Dysphagia, defined as a difficulty in swallowing of fluids and/or solid foods, is one of the most frequent symptoms of esophageal, gastrointestinal, ear, nose and throat diseases. As such, it poses a diagnostic challenge and an interdisciplinary clinical problem. Of particular importance in diagnosis is to distinguish between esophageal and oropharyngeal dysphagia. Oropharyn-geal dysphagia is often associated with neuromuscular disorders and is treated with rehabilitative protocols, while esophageal dysphagia may be due to anatomical alterations and esophageal motility difficulties. While the former can be adequately treated with endoscopic or surgical therapy, the latter are currently trea…

Bisphosphonate-related osteonecrosis of the jaw (BRONJ): run dental management designs and issues in diagnosis

2007

Recently, jawbone osteonecrosis has been largely reported as a potential adverse effect of bisphosphonate (BP) administration. Because of the peculiar pharmacokinetic and pharmacodynamic features of the BF (mainly for i.v. administration), their efficacy and large use, some major issues have to be taken into account extendedly both by oncologists and by dentists: 1) therapeutic dental protocol for patients with diagnosis of bisphosphonate-related osteonecrosis of the jaw (BRONJ); 2) dental strategies for patients in former or current i.v. BF treatment and in absence of BRONJ signs; 3) strategies for patients before i.v. BF treatment. Clinical features and guidelines for the management of th…

Carbamazepine transbuccal delivery: the histo-morphological features of reconstituted human oral epithelium and buccal porcine mucosae in the transmu…

2009

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.

2011

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. The study group comprised 20 samples of OSCC, harvested from 20 oth…

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

2005

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.

DOUBLE DEMONSTRATION OF ONCOGENIC HIGH RISK HUMAN PAPILLOMA VIRUS DNA AND HPV-E7 PROTEIN IN ORAL CANCERS

2011

Oncogenic HPVs are necessarily involved in cervical cancer but their role in oral carcinogenesis is debated. To detect HPV in oral cancer, 38 cases of formalin fixed-paraffin embedded OSCC were studied by both DNA genotyping (MY09/11 L1 consensus primers in combination with GP5-GP6 primer pair followed by sequencing) and immunohistochemistry (monoclonal Abs against capsid protein and HPV-E7 protein, K1H8 DAKO and clone 8C9 INVITROGEN, respectively). HPV-16 tonsil cancer was used as positive control. The overall prevalence of HPV infection in OSCCs was 10.5%. Amplification of DNA samples showed single HPV DNA infection in 3 cases (HPV16; HPV53; HPV70) and double infection in one case of chee…

Orally based diagnosis of celiac disease:current perspective

2008

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…

Inhibiting proliferation in KB cancer cells by RNA interference-mediated knockdown of nicotinamide N-methyltransferase expression.

2011

The enzyme Nicotinamide N-methyltransferase (NNMT) catalyzes the methylation of nicotinamide and other pyridines, playing a pivotal role in the biotransformation and detoxification of many drugs and xenobiotic compounds. Several tumours have been associated with abnormal NNMT expression, however its role in tumour development remains largely unknown. In this study we investigated expression levels of Nicotinamide N-methyltransferase in a cancer cell line and we evaluated the effect of shRNA-mediated silencing of NNMT on cell proliferation. Cancer cells were examined for NNMT expression by semiquantitative RT-PCR and Western blot analysis. A HPLC-based catalytic assay was performed to asses…

Oral lichen planus in children: An Italian case series

2023

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.

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

2008

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 manifestations of celiac disease.

2008

Introduction: Contrary to early beliefs, celiac disease (CD) is relatively common; however, it still remains underdiagnosed since most cases are atypical, with few or no gastrointestinal symptoms and predominance of extraintestinal manifestations. As a consequence, the diagnosis of the disorder often requires a multidisciplinary approach. Also some oral ailments have been described in celiac patients. In this study, we review the papers that have reported oral manifestations in subjects with CD. Methods: A comprehensive literature search was conducted in Medline and Embase databases using appropriate key words. Additional papers were selected by cross-referencing from the retrieved articles…

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

2007

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…

Diagnostic Pathways and Clinical Significance of Desquamative Gingivitis

2008

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…

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

2012

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…

TLR4 expression in ex-Lichenoid lesions—oral squamous cell carcinomas and its surrounding epithelium: the role of tumor inflammatory microenvironment

2022

Toll-like receptors (TLRs) regulate innate and adaptive immune responses. Moreover, TLRs can induce a pro-survival and pro-proliferation response in tumor cells. This study aims to investigate the expression of TLR4 in the epithelium surrounding oral squamous cell carcinomas (OSCC) in relation to its inflammatory microenvironment. This study included 150 human samples: 30 normal oral control (NOC), 38 non-lichenoid epithelium surrounding OSCC (NLE-OSCC), 28 lichenoid epithelium surrounding OSCC (LE-OSCC), 30 OSCC ex-non oral lichenoid lesion (OSCC Ex-NOLL), and 24 OSCC ex-oral lichenoid lesion (OSCC Ex-OLL). TLR4 expression was investigated by immunohistochemistry and the percentage of posi…

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

2018

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…

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

2007

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
