Corrida em esteira e exercícios de força: efeitos agudos da ordem de realização sobre a hipotensão pós-exercício

Este estudo analisou as respostas de pressão arterial sistólica (PAS) e pressão arterial diastólica (PAD) após duas sessões de exercício concorrente realizado em diferentes ordens [aeróbio-força (AF), e força-aeróbio (FA)]. Quinze indivíduos normotensos foram submetidos a duas sessões de exercício realizadas em dias distintos na seguinte sequência AF e FA. A PAS e PAD foram medidas antes e a cada 15 min durante 60 min de recuperação pós-exercício. Houve hipotensão pós-exercício (HPE) para PAS, aos 30 min (-7,4 mmHg), 45 min (-12,14 mmHg) e 60 min (-15,14 mmHg) de recuperação na sessão AF. Já na FA houve HPE apenas aos 60 min (-8,34 mmHg) de recuperação. A variação da PAS e PAD entre as sessões revelou HPE maior aos 15 min, 45 min e 60 min na PAS; e aos 45 min na PAD comparando-se AF a FA. A realização de exercício aeróbio antes do de força resultou em maior HPE para adultos jovens

EPIDEMIOLOGY OF PARACOCCIDIOIDOMYCOSIS

SUMMARYThe epidemiological characteristics of paracoccidioidomycosis were reviewed and updated. The new endemic areas in Brazil were discussed in the section regarding the geographic distribution of the mycosis. Subclinical infection with Paracoccidioides brasiliensis was discussed on the basis of skin test surveys with antigens of the fungus, seroepidemiological studies, and disease cases outside Latin America. Large case series permitted a comparison of the prevalence of the mycosis in different regions, its estimated incidence and risk factors for the development of the disease. Aspects modulating the expression of the clinical forms of paracoccidioidomycosis are also presented. This review also deals with diseases associated with the mycosis, opportunistic paracoccidioidomycosis, lethality, mortality and infection and disease in animals

Cysticercose of the central nervous system: II. Spinal cysticercose

The compromising of the spinal canal by cysticercus is considered infrequent, varying from 16 to 20% in relation to the brain involvement. In the spinal canal the cysticercus predominantly places in the subarachnoid space. Clinical signs in spinal cysticercosis can be caused by direct compression of the spinal cord/roots by cisticerci and by local or at distance inflammatory reactions (arachnoiditis). Another mechanism of lesion is degeneration of the spinal cord due to pachymeningitis or circulatory insufficiency. The most frequent clinical features are signs of spinal cord and/or cauda equina compression. The diagnosis of spinal cysticercosis is based on evidence of cerebral cysticercosis and on neuroradiological examinations (myelography and myelo-CT) that show signs of arachnoiditis and images of cysts in the subarachnoid space and sometimes, signs of intramedullary lesions, but the confirmation can only be made through immunological reactions in the CSF or during surgery. The clinical course of 10 patients with diagnosis of spinal cysticercosis observed among 182 patients submitted to surgical treatment due to this diasease are analyzed. The clinical pictures in all cases were signs of spinal cord or roots compression. All but two presented previously signs of brain cysticercosis. Neuroradiological examinations showed signs of arachnoiditis in 4 patients, images of cysts in the subarachnoid space in 5, and signs of arachnoiditis and images of cysts in one. The 6 patients that presented intraspinal cysts were submitted to exeresis of the cysts and 2 patients with total blockage of the spinal canal underwent surgery for diagnosis. The 2 remaining patients with arachnoiditis and blockge of the spinal canal were clinically treated. All of the six patients submitted to cyst exeresis had initial improvement but 4 of them later developed arachnoiditis and recurrence of the clinical signs and only 2 remained well for long-term. The 2 non operated patients had no improvement of their clinical signs. Two patients died later due to complications of cerebral cysticercosis. Based on the experience acquired in the management of these patients we indicate surgical treatment for patients that present free cyst in subarachnoid space. For those who present arachnoiditis, surgery is indicated only when there is doubt in the diagnosis. Intramedullary cysts should also be surgically treated
