Puberdade precoce associada a tumor misto ovariano (células germinativas- estroma-cordão sexual): aspectos clínicos, diagnósticos e manejo de um caso / Granulosa-stromal tumor of the ovary: a case of mixed germ cell-cord stromal tumor of fhe ovary with endocrinological considerations

Os tumores de estroma ovariano são responsáveis por 5 a 8 por cento dos tumores ovarianos. Sua manifestação clínica inicial mais comum em meninas pré-puberais é o desenvolvimento de puberdade precoce. Neste artigo discutimos o caso de uma menina de 7 anos e 2 meses com tumor de estroma ovariano do tipo misto - cordões-sexuais-células germinativas -, cuja manifestação inicial foi puberdade precoce isossexual, de evolução rápida e progressiva. Os níveis séricos de testosterona, estradiol e 17alfaOH-progesterona encontravam-se elevados. A ecografia pélvica-abdominal demonstrou massa anexal direita. Salpingo-ooforectomia unilateral foi realizada com completa ressecção tumoral. A paciente encontra-se bem 7 anos após a cirurgia com crescimento e desenvolvimento puberal normal, sem evidência de recidiva tumoral. São revistas as principais manifestações clínicas dos tumores ovarianos, sua classificação e o estadiamento dos tumores de estroma ovariano/cordão sexual, seu seguimento empregando diversos marcadores tumorais e hormonais. Finalmente é analisado o tratamento e prognóstico destes pacientes.

Estabelecimento a prevalência de hipertensäo arterial sistêmica. Influência dos critérios de amostragem / Establishing the prevalence of hypertension. Influence of sampling criteria

OBJECTIVE: To compare the prevalence of systemic hypertension in two different populations: a representative sample of the adult urban population of Porto Alegre, and individuals who sought blood pressure measurement in a hypertension prevention and control campaign. METHODS: A cross-sectional study was carried out involving a representative sample of the adult urban population of Porto Alegre and a population sample obtained from a hypertension prevention and control campaign, which included all the individuals who sought the blood pressure assessment unit at the Hospital das Clínicas in Porto Alegre. The following parameters were investigated: history of hypertension, use of antihypertensive drugs, age, and sex. Adjustments for age and sex in the prevalence rates were performed to make them comparable. RESULTS: Hypertension prevalence, defined as values > or = 160/95mmHg or treatment with antihypertensive drugs, was higher in the campaign sample (42 percent) as compared with the population sample (24 percent). Among those who were aware of their hypertensive condition and were under medication, 54 percent of the campaign sample and 62 percent of the representative population sample maintained their pressure levels <160/90mmHg. CONCLUSION: Prevalence rates of hypertension differed a lot in the campaign sample and in the representative population sample, showing that the sampling criterion may influence assessment of risk factors and bias the association between risk factors and health aggravations
