Aim . To assess the epidemiological and clinical factors that influence prognosis of oral oropharyngeal squamous cell carcinoma (SCC). Methods One hundred twenty-one cases SCC were selected. The survival curves for each variable estimated using Kaplan-Meier method. Cox regression model was applied to effect variables on survival. Results Cancers at an advanced stage observed in 103 patients (85.1%). tongue more frequent (23.1%). analysis 59.9% one year, 40.7% two years, 27.8% 5 years. There...

Avulsions are very common in a school setting. Teachers often requested to help such emergency situations. A survey consisting of seven simple questions regarding dental avulsion was answered by 60 teachers from five different elementary schools Rio de Janeiro, Brazil, order evaluate their knowledge on the subject and establish guideline be followed when an accident this type happens. lack technical information observed among teachers; most them intuitively rather than informative basis....

ABSTRACT Oral and subgingival samples from periodontal lesions were collected 54 human immunodeficiency virus (HIV)-positive 20 HIV-negative patients cultured for yeast species. Of the HIV-positive patients, 44 (82%) positive species, of which 29 (66%) subgingival. A total 19 (48%) Candida dubliniensis , 15 (79%) colonized in sites. Seven isolates glabrata two parapsilosis one isolate Saccharomyces cerevisiae recovered. This study reports first time recovery C. intraoral sites confirms...

This study compares the periodontal clinical profile and composition of subgingival microbiota human immunodeficiency virus (HIV)-seropositive HIV-seronegative subjects with chronic periodontitis.A total 172 were distributed into two HIV-seropositive groups (37 periodontitis [H+CP+] 35 periodontally healthy [H+CP-] individuals) (49 [H-CP+] 51 [H-CP-] subjects). Subgingival samples collected from six sites deepest probing depth in random health. All HIV-infected patients had undergone highly...

• Current models for the generation of new gametophytic self-incompatibility specificities require that neutral variability segregates within specificity classes. Furthermore, one predicts greater ratios nonsynonymous to synonymous substitutions in pollen than pistil genes. All assume arise by mutation only. To test these models, 21 SFB (the S-locus) alleles from a wild Prunus spinosa (Rosaceae) population were obtained. For seven these, corresponding S-haplotype was also characterized. The...

Abstract Aim: The anti‐viral efficacy of oral antimicrobial rinses has not been adequately studied in terms potential clinical significance. As a follow‐up to an vitro study on the effect antiseptics Herpes simplex virus, Type 1, this was undertaken evaluate vivo essential oil containing antiseptic reduction viral titer saliva during active infection. Method: Patients were recruited and evaluated single visit protocol at onset perioral outbreak, consistent historically clinically with...

Background: Controversial data regarding the association between immunosuppression and prevalence/ severity of periodontal diseases in HIV infection have been reported. Thus, aim this study was to test hypothesis that lower T CD4 lymphocyte levels are not related a higher prevalence chronic periodontitis HIV‐infected Brazilians undergoing highly active anti‐retroviral therapy (HAART). Methods: Sixty‐four patients under HAART were classified as having periodontitis; i.e., ≥three sites with...

After the introduction of highly active antiretroviral therapy (HAART), several studies have shown a decrease in prevalence HIV-associated oral lesions. The goal this study is to evaluate manifestations HIV Brazil. A retrospective epidemiologic analysis was performed medical records HIV-positive patients who attended Clementino Fraga Filho University Hospital and Stomatology Clinic Federal Rio de Janeiro from 1988 2004. Gender, age, mode transmission, level education, history opportunistic...

Background Head and neck mucosal melanomas ( MM s) are rare tumors with adverse outcomes poorer prognoses than their more common cutaneous counterparts (cutaneous melanomas— CM s). Few studies have compared the expression of mitochondrial dynamic markers in these tumors. This study aimed to assess correlations melanoma progression potential as predictors lymph node involvement distant metastasis. Methods Immunohistochemistry against anti‐mitochondrial AMT ), dynamin‐related protein 1 DRP 1),...

Resumo Objetivo Estimar se variáveis clínicas e epidemiológicas influenciam no atraso do diagnóstico em dois centros de referência. Métodos Foi realizado um estudo analítico longitudinal retrospectivo. Todos os prontuários pacientes maiores 18 anos diagnosticados período junho 2005 a 2013 foram analisados por meio SPSS® 20. Para testar associações entre as com atrasos paciente profissional, utilizados testes: ANOVA, t Student Kruskal-Wallis. Resultados Foram incluídos 121 prontuários....

The association between hearing loss and chronic kidney disease hemodialysis has been well documented. However, the classification used for degree of may underestimate actual diagnosis due to specific characteristics related most affected auditory frequencies. Furthermore, correlations time with handicap remain unknown in this population.To compare results Lloyd's Kaplan's Bureau Internacional d'Audiophonologie classifications patients, correlate averages calculated by their formulas...

The prevalence of HIV-related oral lesions may vary according to socioeconomic status and antiretroviral therapy, among other factors. This study's intent was evaluate the association between indicators, CD4+ counts in city Rio de Janeiro, RJ, Brazil. A retrospective epidemiological analysis performed medical records HIV-positive patients that attended Federal University Janeiro 1997 2004. Gender, age, mode HIV transmission, level education, monthly familial income, were assessed. For...

To investigate risk factors associated with hypovitaminosis D in adult patients infected HIV/aids, at a referral hospital Maceió, Brazil.This cross-sectional study involved 125 evaluated from April to September 2013 by means of interviews, review medical records, physical examination, and laboratory tests. The data were analyzed using the SPSS® software, version 17.0; prevalence mean levels vitamin determined. association between independent variables was assessed Chi-square or Fisher's...
