Avaliação da capacidade cardiorrespiratória (vo2máx) em policiais militares, com testes indiretos / Assessment of cardiorespiratory fitness (VO2máx) in the military police of, with indirect tests

O objetivo deste estudo foi avaliar o (VO2máx) de militares com testes indiretos de 1600m (ALMEIDA et al., 2010) e 12min (COOPER,1968). Participaram 49 militares masculinos, aptos fisicamente, média de idade de 25,6 ±3,10 anos, IMC 23 ±1,4 Kg.m2, selecionados aleatoriamente. O (VO2máx) foi mensurado através das equações de Cooper e Almeida após os testes; coletados e analisados os parâmetros fisiológicos: frequência cardíaca, glicemia e lactato pré e pós-testes e percepção subjetiva do esforço ao final. Observou-se grande fidedignidade entre eles, sendo o valor do (VO2máx) de 1600m (43,63±3,21) superior ao de 12min (39,42±4,18), mostrando aumento significativo (p<0,0001), atribuída à potência de exercício desenvolvida durante o teste, que pode ser observada nos valores de lactato no de 1600m. A prova de 1600m, mostrou-se como uma alternativa eficaz na mensuração do (VO2máx) em militares, portanto sendo uma medida indireta de baixo custo e fácil uso e de grande valia sua aplicabilidade nas Instituições Militares.

The objective of this research was to evaluate the (VO2máx), in indirect tests of 1600m (Almeida et al., 2010) and 12 min (Cooper, 1968). 49 physically fit military aged 25.6±3.10 years, BMI23±1.4 kg.m2, where randomly chosen according to the inclusion criteria of the research took part of it. The (VO2máx) was measured through COOPER and Almeida equations after the tests of 1600m and 12min run, collected and analyzed physiological parameters of cardiac frequency glycemia and lactate were collected before and after the tests. Besides, the subjective perception of effort at the end of each test was evaluated. Through the physiological parameters, it could be observed a great reliability between the 1600m and 12min run tests, in which the (vo2máx) value in the former (43.63±3.21) was higher than in the latter test (39.42±4.18), showing a significant incriase (p<0.0001), attributed to the power developedduring the exercise test, which can be observed for lactate in the 1600m. The 1600m test, proved to be an effective alternative in measuring (vo2máx) in milytary, being an indirect measure of cost and ease of use and great value for their applicability in the military institutions.

Comparative histopathological study of sporotrichosis and American tegumentary leishmaniasis in dogs from Rio de Janeiro.

Pyogranulomatous lesions from 80 dogs with sporotrichosis and 26 dogs with American tegumentary leishmaniasis (ATL) were compared microscopically in order to identify features that would support the diagnostic suspicion and direct the subsequent search for the aetiological agent of either infection. Odds ratios and their respective 95% confidence intervals were calculated in order to evaluate the impact of the microscopical findings on the diagnosis of either disease. Lesions with well-formed granulomata were 14 times more likely to be due to sporotrichosis than ATL. Marked neutrophil infiltration into granulomata was 12.26 times more likely to be associated with sporotrichosis when compared with lesions having mild neutrophilic infiltration. Absence of lymphocytes and macrophages in the peripheral infiltrate was associated with a 9.71 and 4.93 higher chance, respectively, of being sporotrichosis rather than ATL compared with lesions where these cells were present. Lesions with a perivascular, perifollicular and interstitial peripheral inflammatory infiltrate were 5.48 times more likely to be due to sporotrichosis than ATL when compared with lesions with a diffuse peripheral infiltrate. Histopathological analysis may therefore contribute to the diagnosis of sporotrichosis or ATL skin lesions in dogs since this method permits the identification of features that direct the diagnostic suspicion, thus facilitating the search for the aetiological agent in histological sections, permitting the precise request of subsequent tests and thereby reducing costs and time taken to achieve a definitive diagnosis and the initiation of appropriate therapy.

Histopathology of canine sporotrichosis: a morphological study of 86 cases from Rio de Janeiro (2001-2007).

The present study reports the histopathological findings of 86 skin lesions of dogs with sporotrichosis from Rio de Janeiro. Suppurative granulomatous inflammation was the predominant finding and was observed in 76 (88.37%) cases. Plasma cells surrounding the suppurative granulomas were detected in 68 (89.5%) cases and an inflammatory infiltrate at the periphery of these granulomatous lesions was observed in 63 (82.9%). Fungus-specific staining revealed yeast cells compatible with Sporothrix schenckii in 36 cases. These fungal elements were only detected in lesions characterized by suppurative granulomatous inflammation. Thus, specific staining of serial sections is recommended in the case of dogs with skin lesions whose histopathological presentation is consistent with sporotrichosis. However, due to the generally small number of yeast cells in lesions, the hypothesis of sporotrichosis should not be ruled out even if the result is negative, especially in epidemic areas where correlation with epidemiological data is particularly useful.

Mycological evaluation of bronchoalveolar lavage in cats with respiratory signs from Rio de Janeiro, Brazil.

Twenty-three cats with respiratory signs who had domiciliary contact with cats with sporotrichosis were studied. Sneezing was the predominant extracutaneous sign. Twelve cats had no skin lesions and 11 had ulcerated skin lesions. Mycological culture of material obtained from the nasal cavity, oral cavity, bronchoalveolar lavage (BAL) and skin lesions, when present, was performed for all cats. In the case of autopsy, lung fragments were cultured. Sporothrix schenckii was isolated from four of the 12 cats without skin lesions: BAL (one cat) and oral and/or nasal cavity (three cats). The latter three animals developed nasal and distant skin lesions within the following 2-4 weeks. The cat with S. schenckii isolated from BAL did not develop skin lesions or lower respiratory tract symptoms during the 6 months of follow-up. S. schenckii was isolated from one or more biological samples of all 11 cats with skin lesions: oral cavity (five), nasal cavity (eight), BAL fluid (four), skin lesions (eight), and blood culture (one). No yeast-like structures were observed upon BAL cytology in any of the 23 cats. The results suggest that S. schenckii can cause infection of skin contiguous to the natural facial orifices through colonisation of the mucosal surfaces of the upper airways.

American cutaneous leishmaniasis in two cats from Rio de Janeiro, Brazil: first report of natural infection with Leishmania (Viannia) braziliensis.

We describe the isolation of Leishmania (Viannia) braziliensis from two female cats with American cutaneous leishmaniasis in Rio de Janeiro, Brazil. The isolates were identified as L. (V.) braziliensis by isoenzyme electrophoresis.

Fagotipagem e resistencia as drogas de amostras de Staphylococcus aureusmultiresistentes no HU/UFPB / Phage typing and drug resistence in multiple-antibiotic-resistant Staphylococcus aureus in a university hospital

Foi realizado um estudo epidemiologico de 38 amostras de Staphylococcus aureus isolados de pacientes internos no Hospital Universitario da UFPb. Em sua aioria, aslinhagens estudadas apresentaram multiresistencia as drogas, das quais 31,6% demonstraram resistencia a oxacilina (ORSA). A partir de testes de sensibilidade as drogas determinou-se o padrao de resistencia das amostras estudadas, com especial atençao as amostras ORSA nas quais foi detectada uma resistencia media de 75,0% a bateria de drogas utilizadas. As amostras foram submetidas a fagotipagem utilizando a RTD e100xRTD obtendo-se 22/38 (57,9%) de amostras tipaveis, sendo a maioria 11/22 (50,0%) caracterizada no grupo fagico III. No entanto,considerando o elevado numero de amostras nao tipaveis, e que coincidiu em grande parte dos casos com cepas de resistencia elevada, concluimos ser necessario a utilizaçao de tecnicas moleculares para melhor estabelecer a analise epidemiologica.

[Centrifugal annular erythema caused by insect bites]. / Eritema anular centrífugo por picada de inseto.

The authors present a case of a 4 1/2 years old child who showed erythema annulare with generalized lesions which extended centrifugally. The lesions was present since 1 month after birth and she never been free of them until few days after she start to use insect antigen vaccine, when they disappeared entirely.
