Epstein-Barr Virus-Associated Carcinoma of the Larynx: A Systematic Review with Meta-Analysis.

Over the past few decades, several publications have investigated the role of Epstein-Barr virus (EBV) in head and neck squamous cell carcinomas, and an increasing number of them have shown its presence in laryngeal tumors. The purpose of this meta-analysis was to evaluate the association of EBV with laryngeal carcinoma. The search was carried out in two databases, Scopus and PubMed, using the following terms: "Epstein-Barr virus" and "laryngeal carcinoma". A total of 187 records were found, of which 31 were selected for meeting the inclusion and exclusion criteria. The meta-analysis yielded an overall pooled prevalence of 43.72% (95% confidence interval (CI): 34.35-53.08). Studies carried out in Europe and Eurasia had slightly higher pooled prevalence than other subgroups, while the prevalence of studies performed in developed countries was higher than in developing countries (46.37% vs. 34.02%). Furthermore, laryngeal carcinoma occurred almost three times as often among EBV-infected individuals compared to those without EBV infection (odds ratio = 2.86 (95% CI: 1.18-6.90); Begg's test, p = 0.843 and Egger's test, p = 0.866). Our findings support the idea that EBV is related to laryngeal carcinoma. However, further studies are needed before recognizing a definitive etiological role of EBV in the development and/or progression of laryngeal carcinomas.

Risk factors for suicide in bipolar disorder: a systematic review.

BACKGROUND: Bipolar disorder confers the highest risk of suicide among major psychological disorders. The risk factors associated with bipolar disorder and suicide exist and are relevant to clinicians and researchers. OBJECTIVE: The aim of the present study was to conduct a systematic review of articles regarding the suicide risk factors in bipolar disorder. METHODS: A systematic review of articles on suicide risk factors in bipolar disorder, published from January 1, 2010 to April 05, 2014, on SCOPUS and PUBMED databases was carried out. Search terms were "Suicide" (medical subject headings [MeSH]), "Risk factors" (MeSH), and "Bipolar" (keyword). Of the 220 retrieved studies, 42 met the eligibility criteria. RESULTS: Bipolar disorder is associated with an increased rate death by suicide which contributes to overall mortality rates. Studies covered a wide range of aspects regarding suicide risk factors in bipolar disorder, such as risk factors associated to Sociodemographic conditions, Biological characteristics, Drugs Relationships, Psychological Factors, Genetic Compound, Religious and Spirituals conditions. Recent scientific literature regarding the suicide risk factors in bipolar disorder converge to, directly or indirectly, highlight the negative impacts of risk factors to the affected population quality of life. CONCLUSION: This review demonstrated that Bipolar disorders commonly leads to other psychiatric disorders and co-morbidities involving risk of suicide. Thus the risk factors are relevant to have a better diagnosis and prognosis of BD cases involving risk of suicide.

Amelogênese imperfeita em paciente nefropata: relato de uma reabilitação oral conservadora / Amelogenesis imperfecta in a patient with kidney disease: a report of a conservative oral rehabilitation

Amelogênese imperfeita é uma doença hereditária que afeta a formação do esmalte, tanto na dentição decídua como na permanente. Ela também pode ser associada com alterações morfológicas e bioquímicas em outra parte do corpo. O diagnóstico da amelogênese imperfeita envolve a exclusão de fatores ambientais e o estabelecimento de um provável padrão de herança genética, reconhecimento do fenótipo e correlação com a formação do esmalte. Numerosas modalidades de tratamento têm sido descritas para a reabilitação de pacientes com amelogênese imperfeita. No entanto, tem-se buscado reabilitar de maneira conservadora e com um enfoque na prevenção dos efeitos dessa patologia. Este trabalho tem por objetivo relatar um caso clínico de reabilitação estética e funcional por meio do uso de resinas compostas, em um paciente com amelogênese imperfeita e que apresentava hiperplasia gengival devido ao uso de imunossupressores. Pôde-se concluir que é possível melhorar a estética e restabelecer a função destes pacientes através de procedimentos e técnicas simples e de baixo custo.

Amelogenesis imperfecta is a hereditary disease that disrupts enamel formation, affecting both the deciduous and permanent teeth. It can also be associated with morphological and biochemical changes elsewhere in the body. The diagnosis of amelogenesis imperfecta involves the exclusion of environmental factors and the establishment of a likely pattern of inheritance, recognition of the phenotype and correlation with enamel formation. Numerous treatment modalities have been described for the rehabilitation of patients with amelogenesis imperfecta. However, rehabilitation is preferably conservative, focusing on preventing the effects of this pathology. The aim of this paper is to report a case of aesthetic and functional rehabilitation of a patient with amelogenesis imperfecta and immunosuppressant-induced gingival hyperplasia using composite resins. In conclusion, it is possible to improve the aesthetics and restore the function of these patients with simple and inexpensive procedures and techniques.
