Resumo em Português:

Em um serviço especializado de hospital universitário da cidade de São Paulo, Brasil, ficaram analisados o número de pacientes com calazar atendidos e as localidades onde a parasitose foi adquirida, bem como alguns fatos correlatos. Em período de 12 anos e três meses ocorreu internação de 62 enfermos, configurando a taxa de 0,91% em relação a 6.798 indivíduos. Esse valor e a cifra de óbitos, correspondente a 19,33%, representaram a expressividade da doença, que não é incomum e desprovida de gravidade.

Resumo em Inglês:

In order to figure out basically a situation strictly connected with medical assistance work and also to cooperate with public health authorities, analysis of patients with kala-azar was made in a specialized ward of a university hospital of the city of S. Paulo (Brazil). The patients, the locale where their protozoosis was acquired, and related data were analyzed. This study was made of patients hospital registered in 12 years and 3 months. Sixty-two were bearers of kala-azar, at a rate of 0.91% out of a total of 6,798 hospitalized patients. Sixty-two were bearers of kala-azar, 0.91% of the total. Mortality was 19.3%. Both figures, 0.91% and 19.3%, define the importance of the disease, which is severe and rather frequent. The date obtained from the survey, especially that related to the geographic distribution of the infection, will undoubtedly help to better evaluate the protozoosis in question.

Foram aplicados, o teste de Mantoux e uma prova intradérmica dupla de tuberculina (PID), em 131 pacientes hospitalizados para elucidação de diagnóstico, sendo os resultados comparados estatisticamente com o diagnóstico final obtido por métodos clínicos, cirúrgicos e laboratoriais. O teste de Mantoux lido às 72 h seguido de nova aplicação de PPD no mesmo local, sendo lida a nova reação após 24 h constitui a prova intradérmica dupla (PID), sendo o resaltado final obtido da diferença em mm entre a primeira e a segunda leitura. A análise estatística mostrou que a PID é melhor que o teste de Mantoux, com menos erros, menos reações falsas-positivas, probabilidade nula de dar falsos-negativos, maior sensibilidade e maior especificidade. Concluiu-se que a PID pode ser usada em elucidação de diagnóstico e em inquéritos de saúde pública em tuberculose.

Resumo em Inglês:

The Mantoux test and a double intradermal tuberculin test (PID), were carried out on 131 patients hospitalized for diagnostic elucidation. Comparison was made between the results of the two intradermal tests and the final diagnosis, obtained by clinical, surgical and laboratory methods, and the data were submitted to statistical analysis. Measuring Mantoux reaction after 72 h, and injecting a new intradermal dose of PPD at exactly the same point and repeating the reading after another 24 h, the difference in size (mm) between the first and second readings may be interpreted in three different ways: 1) A difference of less than 3 mm between the two readings: nill statistical probability of patient with tuberculosis. 2) A difference of 3 mm or more, with maximal reaction diameter of 9 mm: indecisive result; patient probably without tuberculosis, however it is suggested that a new PID should be carried out after another 90 days. 3) A difference of 3 mm or more, with maximal reaction of 10 mm or more: patient probably has tuberculosis. The statistical analysis showed that the PID test is better than the Mantoux test, presenting fewer errors, less false-positive results, nill probability of false-negative results, better sensibility and specificity. The conclusion was drawn that the PID is a test that can be used in diagnostic elucidation and publici health surveys on the incidence of tuberculosis.
