A pioneering epidemiological study investigating the incidence of squamous cell carcinoma of tongue in a Portuguese population
2012
Objective: The purpose of this study was to investigate the incidence of squamous cell carcinoma (SCC) of the anterior two thirds of the tongue in a population living in central and southern Portugal, all treated at Portuguese Institute of Oncology of Lisbon, Francisco Gentil (IPOLFG). Study Design: This study was a retrospective review of all patients who had a histopathological diagnosis of SCC of the anterior two thirds of the tongue and had been treated in the Head and Neck Surgery Unit at the IPOLFG (Lisbon, Portugal), between 1st January 2001 and 31st December 2009. The risk factors evaluated were: gender; age; alcohol consumption; tobacco use; prosthesis use and the carcinoma site. R…
Candidal carriage in the oral cavity of human immunodeficiency virus–infected subjects
2002
Abstract Objectives. We sought to assess asymptomatic oral carriage of Candida species and relative density in human immunodeficiency virus-infected (HIV+) subjects, as well as to determine whether yeast carriage is associated with CD4+cell count, HIV-1 RNA quantity, gender, route of HIV transmission, antiretroviral therapy, or smoking. Study Design. A cross-sectional analysis of oral rinses from HIV+ and healthy subjects was undertaken. Oral candidal carriage and relative species were investigated in 42 HIV+ and 41 healthy individuals, all of whom were seen at the Palermo University Department of Oral Sciences, Italy. Data were managed and analyzed by means of the computer software package…
Radiation-related superficial oral mucoceles : an under-recognized acute toxicity in head and neck cancer patients
2018
Background Acute toxicity is usually defined as adverse changes occurring immediately or a short time after the start of oncological treatment. Material and Methods Cross-sectional retrospective study performed with head and neck cancer patients who underwent radiotherapy from 2013 to 2016. Results Ten (1.2%) patients developed SOMs during radiotherapy, most (80%) of which were men with a mean age of 59.5 years at diagnosis. SOMs mainly affected the floor of the mouth (60%) between the fourth and the sixth weeks of radiation therapy. All lesions were asymptomatic and spontaneously ruptured approximately 9 days after diagnosis. Conclusions Although rare, SOMs may be regarded as an acute oral…
Venous thromboembolism after oral and maxillofacial oncologic surgery: Report and analysis of 14 cases in Chinese population.
2016
Background Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. Material and Methods The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. Results 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT,…
Factors related to late stage diagnosis of oral squamous cell carcinoma.
2010
Aims: To identify factors related to advanced-stage diagnosis of oral cancer to disclose high-risk groups and facilitate early detection strategies. Study design: An ambispective cohort study on 88 consecutive patients treated from January 1998 to December 2003. Inclusion criteria: pathological diagnosis of OSCC (primary tumour) at any oral site and suffering from a tumour at any TNM stage. Variables considered: age, gender, smoking history, alcohol usage, tumour site, macroscopic pattern of the lesion, co-existing precancerous lesion, degree of differentiation, diagnostic delay and TNM stage. Results: A total of 88 patients (mean age 60±11.3; 65.9% males) entered the study. Most patients (…
Placement of endosseous implants in patients with oral epidermolysis bullosa.
2000
Abstract Objective: To evaluate the feasibility of placing endosseous implants in patients with recessive dystrophic epidermolysis bullosa. This article reports on 4 patients subjected to follow-up. Study Design: Implants were placed in 4 cases. All patients have marked oral involvement, with devastating alterations in the soft and hard tissues in all cases. Results: A total of 15 implants (7 maxillary, 8 mandibular) were placed. All implants integrated successfully and have been restored. The average follow-up from implant placement was 2.5 years (range, 1-4). Conclusions: Our preliminary findings suggest that endosseous implants can be successfully placed and can provide support for prost…
Survival and tissue maintenance of an implant with a sloped configurated shoulder in the posterior mandible-a prospective multicenter study.
2016
Aim Clinical studies evaluating the influence of the implant design on the preservation of peri-implant keratinized mucosa are rare. The aim of this prospective multicenter study was to investigate the survival, and soft and hard tissue maintenance of an implant with a sloped shoulder configuration, when placed in the posterior mandible. Material and Methods In this study, 24 centers participated and 184 patients receiving 238 implants (OsseoSpeed™ Profile TX implants) were included. Clinical assessments of soft tissue parameters were performed before implant placement, immediately after implant placement, at prosthetic delivery and at 6, 12 and 24 months after implant placement and margina…
The Buccal Mucosal Graft For Urethral Reconstruction: A Preliminary Report
1992
Autologous buccal mucosa as a substitute for urethral epithelium was studied in 2 dogs and used in 6 patients with difficult urethral reconstruction problems. The indications for an operation in these patients were failed hypospadias repairs with limited skin in 3, severe structure disease after hypospadias repair in 1, a short urethra in 1 and epispadias in 1. Three urethral fistulas and 1 meatal stenosis occurred in 3 patients. No urethral stricture or diverticulum was noted, and the final outcome was good functionally and cosmetically in all patients. This technique is useful for urethral reconstruction when local skin is not available.
Oro-facial aspects of leprosy : report of two cases with literature review
2009
Leprosy is a chronic infectious disease affecting primarily the skin, peripheral nerves, respiratory system and the eyes. Leprosy induces various types of clinical presentation affecting the patient´s immune response. Cellmediated immunity is considered to be the crucial defence against the disease and the magnitude of this immunity defines the extent of the disease. The article presents two case reports of manifestations of leprosy in the oro-facial region, with a brief review of various other important oro-facial manifestations of leprosy. The first report deals with granulomatous nodules in the palate while the second report presents bilateral facial palsy in leprosy patients. Both the r…
Use of Bichat's buccal fat pad for the sealing of orosinusal communications. A presentation of 8 cases.
2011
Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusal communications, describe the surgical technique used, and report the main complications. Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the University of Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007 and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem. Results: All of the orosinusal communications were successfully resolved with this technique. The immediate postoperative complications were pain (37.5%), inflammation (37.5%)…
