[Prevalence of respiratory symptoms in areas of the Federal District, Brazil]. / Prevalência de sintomáticos respiratórios em regiões do Distrito Federal, Brasil.

The identification of individuals with respiratory symptoms (RS) is important for the early detection of tuberculosis. The aim of this study was to estimate the prevalence of RS in three administrative regions of the Federal District, Brazil. For this, we used the 30 by 7 cluster sampling technique proposed by the World Health Organization. Individuals with RS were defined as those aged 15 years or older living in the administrative regions of Estrutural, Itapoã, or Varjão and reporting a cough lasting at least 3 weeks at the date of the interview. The prevalence of RS was 5.7% in Estrutural and Varjão (95% CI: 2.4-9.0) and 4.8% in Itapoã (95%CI: 1.6-7.9), with a design effect close to 1.0. In Estrutural and Itapoã, fewer years of schooling, and in Itapoã and Varjão, lower income, were associated with RS. Cigarette smoking was associated with the presence of RS in all regions. The prevalence of RS in the three administrative regions investigated is consistent with that of other areas with a similar socioeconomic profile.

Continuous infusion of amphotericin B deoxycholate in the treatment of cryptococcal meningoencephalitis: analysis of safety and fungicidal activity.

We measured fungicidal activity of continuous infusion of amphotericin B deoxycholate plus 5'flucytosine using quantitative cultures of cerebrospinal fluid (CSF) obtained from lumbar punctures of human immunodeficiency virus (HIV)-infected patients with neurocryptococcosis during 14 days of treatment. Glomerular renal function was preserved in all patients. Mycological efficacy with progressive reduction in CSF cryptococcal colony-forming units was comparable to standard 4-h infusion of amphotericin B.

Biopsy of peripheral lymph nodes: a useful tool to diagnose opportunistic diseases in HIV-infected patients.

Peripheral lymphadenopathy is commonly present in HIV-infected patients and has a wide spectrum of differential diagnoses. We carried out a cross-sectional study of peripheral lymph node biopsies performed from January 2004 to December 2008 in HIV-infected patients who attended a tertiary-care hospital in southern Brazil. Only 60 of 210 peripheral lymph node biopsies performed (28%) were non-diagnostic. The most common diagnoses included: mycobacteriosis (105 cases; 50.2%); lymphoma (19 cases; 9.0%); systemic mycosis (12 cases; 5.7%) including histoplasmosis, cryptococcosis and histoplasmosis; and metastatic cancer (2.9%). Peripheral lymph node biopsy is a simple and useful tool to diagnose opportunistic diseases in HIV-infected patients.

Chronic slowly progressive monoarthritis tuberculosis of the hip without systemic symptoms mimicking osteoarthritis: a case report.

The authors report and discuss the clinical and radiological features of a immunocompetent patient with chronic progressive monoarthritis tuberculosis of the hip without systemic symptoms such as fever, and weight loss presenting as caseating abscess and severe destruction of the hip joint, treated with resection arthroplasty.

Prevalência de sintomáticos respiratórios em regiões do Distrito Federal, Brasil / Prevalence of respiratory symptoms in areas of the Federal District, Brazil

A captação de sintomáticos respiratórios (SR) é importante para a detecção precoce de tuberculose. O objetivo deste estudo foi estimar a prevalência de SR em três regiões administrativas (RA) do Distrito Federal, Brasil. Para tanto, foi utilizada a técnica de amostragem por conglomerados (30 por 7) proposta pela Organização Mundial da Saúde. Foram definidos como SR os indivíduos com 15 anos ou mais residentes nas RAs Estrutural, Itapoã ou Varjão e que apresentassem tosse há pelo menos 3 semanas na data da entrevista. A prevalência de SR em Estrutural e Varjão foi de 5,7 por cento (IC95 por cento: 2,4 a 9,0), e em Itapoã, de 4,8 por cento (IC95 por cento: 1,6 a 7,9), com efeito de desenho próximo de 1,0. Em Estrutural e Itapoã, menos anos de estudo, e em Itapoã e Varjão, menor renda, estiveram associados com ser SR. O tabagismo esteve associado com a presença de sintomas respiratórios em todas as RAs. A prevalência de SR está de acordo com aquela encontrada em outras áreas com perfil socioeconômico semelhante ao das áreas estudadas.
