Epidemology and clinical aspects of human rabies in Minas Gerais, Brasil: misdiagnosis and misunderstandings on the psychopathological disturbances

This paper reports 40 cases of human rabies studied at the Carlos Chagas Hospital of UFMC, State of Minas Gerais, Brazil, from 1963 through 1976. From the epidemioiogical point of view it is concluded that the magnitude of the problem of human rabies in underdeveioped countries remains quite unknown. Speciai emphasis is given to the lack of apropriate knowledge of the recommended preventive measures, and to the influence of health education and socio-economic-cultural structure of the communities. The classic clinical picture of human rabies is briefiy described, particular attention being drawn to psychopathologic features of rabies encephalomyeiitis. it is pointed out that in some cases the mental symptoms may predominate from the onset of the illness, adding difficuity to the diagnosis. According to the Authors, human rabies must be differentiated from several psychopathologic syndromes and also from encephalomyelitis due to other central nervous system infections. It is discussed whether the fataiistic concept of human rabies would be somehow contributing to delay a better understanding of the natural history of the disease.

Quantitative Analysis of Immunoglobulin E Reactivity Profiles in Patients Allergic or Sensitized to Natural Rubber Latex (Hevea Brasiliensis)

Characterized native and recombinant Hevea brasiliensis (rHev b) natural rubber latex (NRL) allergens are available to assess patient allergen sensitization profiles. OBJECTIVE: Quantification of individual IgE responses to the spectrum of documented NRL allergens and evaluation of cross-reactive carbohydrate determinants (CCDs) for more definitive diagnosis. METHODS: Sera of 104 healthcare workers (HCW; 51 German, 21 Portuguese, 32 American), 31 spina bifida patients (SB; 11 German, 20 Portuguese) and 10 Portuguese with multiple surgeries (MS) were analysed for allergen-specific IgE antibody (sIgE) to NRL, single Hev b allergens and CCDs with ImmunoCAP technology. RESULTS: In all patient groups rHev b 5-sIgE concentrations were the most pronounced. Hev b 2, 5, 6.01 and 13 were identified as the major allergens in HCW and combined with Hev b 1 and Hev b 3 in SB. In MS Hev b 1 displayed an intermediate relevance. Different sIgE antibody levels to native Hevea brasiliensis (nHev b) 2 and rHev b 6.01 allowed discrimination of SB with clinical relevant latex allergy vs. those with latex sensitization. Sensitization profiles of German, Portuguese and American patients were equivalent. rHev b 5, 6.01 and nHev b 13 combined detected 100% of the latex-allergic HCW and 80.1% of the SB. Only 8.3% of the sera showed sIgE response to CCDs. CONCLUSIONS: Hev b 1, 2, 5, 6.01 and 13 were identified as the major Hev b allergens and they should be present in standardized latex extracts and in vitro allergosorbents. CCDs are only of minor relevance in patients with clinical relevant latex allergy. Component-resolved diagnostic analyses for latex allergy set the stage for an allergen-directed immunotherapy strategy

Distribuição e índice de infecção natural de triatomíneos capturados na região de Campinas, São Paulo, Brasil

Entre 1974 e 1981 em 53 municípios pertencentes à região administrativa de Campinas, SP, foram coletados pela SUCENe encaminhados ao laboratório deMogi- Guaçu, 36.406 triatomíneos, dos quais foram examinados 33.131 exemplares; destes, foram observados 3.176 (9,60%) infectados peloT. cruzi. No referente ao local de captura, constatou-se que 4.516 (12,40%), foram encontrados nas casas, sendo 1.827 (40,46%) habitadas e a grande maioria, 30.460 exemplares (83,67%) coletados em anexos de diferentes tipos e os 1.429 (3,92%) restantes em focos silvestres. A espécie predominante foi o P. megistus, com 33.263 exemplares capturados e também aquela de maior índice de infecção pelo T. cruzi (10, 26%).

The indeterminate form of human chronic Chagas' disease: a clinical epidemological review

Data on the epidemiology and the natural history of the indeterminate form of human chronic Chagas' disease (IFCCD) are discussed, revealing its great importance in endemic areas of Brazil. The work shows that IFCCD presents a gradual and very slow course, causing a benign picture in the studied patients. Evolution patterns, prognostic and anatomopathological features are also discussed. For practical purposes, the classical concept of IFCCD proved to be simple, operational and consistent, It is defined by the absence of symptoms and clinical findings in chronic infected patients with positive serology and/or parasitological examinations for Trypanosoma cruzi coupled with normal electrocardiographic and radiological exams (heart, oesophagus and colon X-Rays). If a patient is submitted to more rigorous and sophisticated tests, these can reveal some alterations, generally small ones and unable to interfere with the prognosis of the infection. It is suggested that research lines specially related to the evolution ary factors and immunological involvement during this phase be adopted.

Pesquisa da infecção natural por Yersinia pestis, em pulicídeos provenientes de focos pestosos do nordeste do Brasil

Foram avaliados três processos de acondicionamento e transporte de pulgas, objetivando análise bacteriológica para isolamento da Yersinia pestis. As três abordagens testadas foram: pulgas vivas em tubos de ensaio com tiras dobradas de papel de filtro; pulgas em solução salina; macerados de pulgas em meio de Cary-Blair. Os dois últimos métodos foram quase iguais e superiores ao primeiro. Foram analisadas pelas três técnicas, um total de 29.512 "pools" de pulicideos provenientes de focos de peste do Nordeste do Brasil no período de 1966 a 1982. Deste total, 236 (0,80%) dos "pools" foram positivos por cultura e/ou inoculação em animais sensíveis.

Parasitismo natural de ovos de triatomíneos por Telenomus fariai lima, 1927 no laboratório

Em novembro/89 verificou-se que o insetário do Centro de Estudos Emmanuel Dias - Bambuí/MG apresentava alta infestação pelo micro himenóptero Telenomus fariai. Em 529 ovos de Panstrongylus megistus e Triatoma vitticeps examinados, 375 (70,9%) apresentavam 1043 exemplares de T. fariai, sendo 955 (91,4%) fêmeas e 90 (8,6%) machos. A seguir, verificou-se também oparasitismo de ovos de Triatoma infestans, e ausência de infestação de ovos de Rhodnius neglectus. As médias de parasitóide por ovo observadas foram de 7,9 em P. megistus; 8,7 em T. vitticeps e 10 em T. infestans. A importância do relato deve-se à possibilidade da infestação de colônias mantidas para fins de pesquisa a partir da introdução em insetários de ovos procedentes do campo, com o estabelecimento de altas taxas de infestação e acentuado declínio da criação. O isolamento e a eliminação dos parasitóides pelo manejo dos ovos parasitados e vedação dos frascos do insetário com tecido de malha estreita (em tomo de 0,25mm) mostraram-se eficientes no controle do T. fariai.
