Body composition was evaluated by dual-energy X-ray absorptiometry and dynamic muscle strength was assessed by one-maximum repetition (1RM) tests in leg press, bench press and biceps curl exercises. Six-minute walk test, Timed Up and Go (TUG); 30-second sitting-rising; arm curl using a 2-kg dumbbell, sit-and-reach (flexibility), and vertical jump tests were performed.Results: There was no difference between groups regarding age (P = 0.49), height (P = 0.46), body fat (%) (P = 0.19), systolic (P = 0.64), diastolic (P = 0.41) and mean blood pressure (P = 0.86), 30-second sitting-rising (P = 0.57), 30-s arm curl (P = 0.73), leg press 1RM (P = 0.51), bench press 1RM (P = 0.77), and biceps curl 1RM (P = 0.85). However, women without the MetS presented lower body mass (P = 0.001), body mass index (BMI) (P = 0.0001), waist circumference (P = 0.02), waist-to-height ratio (P = 0.02), fat body mass (kg) (P = 0.05), lean body mass (kg) (P = 0.02), blood glucose (P = 0.05), triglycerides (P = 0.03), Z-score for the MetS (P = 0.05), higher high-density lipoprotein-cholesterol (HDL-C) (P = 0.002), better performance on TUG (P = 0.01), flexibility (P = 0.03), six-minute walk test (P = 0.04), vertical jump (P = 0.05) and relative muscle strength for leg press (P = 0.03), bench press (P = 0.04) and biceps curl (P = 0.002) exercises as compared to women with the MetS.Conclusion: Elderly women with the MetS have higher metabolic risk profile and lower functional capacity, muscle strength, lower limb power and flexibility as compared to women without the MetS. The evaluation of functional capacity may help to determine the degree of physical decline in older persons with the MetS, while exercise interventions should be encouraged.Keywords: metabolic syndrome, functional capacity, muscle performance, agin

Perfil da vÃtima atendida pelo serviço pré-hospitalar aéreo de Pernambuco
Estudo do tipo descritivo-exploratório com abordagem quantitativa sobre o perfil da vÃtima atendida pelo serviço pré-hospitalar aéreo de Pernambuco. As ocorrências foram avaliadas no perÃodo de agosto de 2007 a julho de 2008, correspondentes ao primeiro ano de funcionamento do hangar no Recife. Nesse perÃodo, foram estudados 283 fichas de ocorrências, com média de 23 atendimentos mensais. Dos vôos, 66% foram de resgate, com 11 minutos de tempo-resposta. Quanto à causa do atendimento, 79% foram por causas externas, na sua maioria de acidentes de trânsito. Prevaleceu o sexo masculino com faixa etária mediana de 34 anos. O resgate dessas vÃtimas graves deve ser realizado de forma rápida e eficaz, por isso analisou-se a relação da gravidade da vÃtima com o tempo-resposta
Concomitância de leishmanioses e infecção pelo vÃrus da imunodeficiência humana (HIV): estudo de quatro casos Concurrent leishmaniasis and human immunodeficiency virus infection: a study of four cases
São apresentados quatro casos de leishmaniose em pacientes com SIDA, sendo dois de leishmaniose visceral e dois com forma cutâneo-mucosa. Lesões cutâneas e de mucosa oral, disseminadas, estavam presentes nos pacientes com a forma tegumentar da doença. Febre prolongada, hepatoesplenomegalia e pancitopenia foram as manifestações principais da forma visceral. A contagem de linfócitos T CD4+ era baixa em todos os casos. A pesquisa de leishmanias foi positiva no aspirado de medula óssea e na biópsia de lesões cutâneas e mucosas. Os pacientes responderam ao tratamento com antimoniais pentavalentes e com a anfotericina B. Poucos casos de coinfecção leishmaniose e HIV têm sido descritos em nosso meio. Apesar da ampla expansão de ambas, até agora suas áreas de distribuição geográfica teve pouca superposição. Os autores recomendam a inclusão desta parasitose no diagnostico diferencial das doenças oportunistas que acometem indivÃduos com SIDA.<br>Few cases of concurrent leishmaniasis and HIV infection have been reported in Brazil, despite both infections being in expansion. Two cases of visceral leishmaniasis and two cases of mucocutaneous leishmaniasis are discussed. Disseminated skin and oral lesions were found in the patients with the cutaneous form of the disease. Prolonged fever, hepatosplenomegaly and pancytopenia were the main manifestations of the visceral form. The CD4 T lymphocyte count was low in all cases. Direct examination of bone marrow aspirate for leishmania and biopsy of cutaneous lesions are the techniques of choice to confirm diagnosis. Pentavalent antimonials and amphotericin B are preferred drugs for the treatment of leishmaniasis, including patients with AIDS. The authors recommend the inclusion of this parasitosis in the differential diagnosis of opportunistic diseases in patients with AIDS
