ABSTRACT

Estimates of occult hepatitis B virus (HBV) infection prevalence varies among different studies depending on the prevalence of HBV infection in the study population and on the sensitivity of the assay used to detect HBV DNA. We investigated the prevalence of occult HBV infection in cirrhotic patients undergoing liver transplantation in a Brazilian referral center. Frozen liver samples from 68 adults were analyzed using a nested polymerase chain reaction assay for HBV DNA. The specificity of the amplified HBV sequences was confirmed by direct sequencing of the amplicons. The patient population comprised 49 (72.1%) males and 19 (27.9%) females with a median age of 53 years (range=18-67 years). Occult HBV infection was diagnosed in three (4.4%) patients. The etiologies of the underlying chronic liver disease in these cases were alcohol abuse, HBV infection, and cryptogenic cirrhosis. Two of the patients with cryptic HBV infection also presented hepatocellular carcinoma. Markers of previous HBV infection were available in two patients with occult HBV infection and were negative in both. In conclusion, using a sensitive nested polymerase chain reaction assay to detect HBV DNA in frozen liver tissue, we found a low prevalence of occult HBV infection in cirrhotic patients undergoing liver transplant, probably due to the low prevalence of HBV infection in our population.

ABSTRACT

Mulher, 73 anos, apresenta-se con Doença de Parkinson(DP) em fase avançada sem resposta a medicaçäo classica, associada a quadro depressivo maior. Foi submetida a sete sessöes de ECT com boa toleräncia. A resposta tanto da sintomatologia depressiva quanto das manifestaçöesparkinsonianas (mensurada pela escala de Webster) foi considerada satisfatória. No entanto, a recidiva dos sintomas parkinsonianos e depressivos ocorreu em tempo relativamente curto. Recomendamos que esta modalidade terapêutica seja considerada em pacientes portadores de DP avançada sem resposta à terapêutica clássica principalmente se associada à depress

ABSTRACT

Embora as linhas mestras do tratamento da hipertensão arterial sistêmica variem amplamente em todo o mundo, os diuréticos representam as drogas de primeira linha. Entretanto, o seu uso deve ser extremamente cuidadoso, já que em dose mais elevada determina distúrbios metabólicos que podem agravar o prognóstico.
