A new cross-sectional survey of household- associated mongrel dogs as well as follow-up of previously parasitemic individuals was carried out in 1984 toy means of xenodiagnosis and serologic techniques to get a deeper insight into the relationship of T. cruzi parasitemia and age among canine hosts in a rural area of Argentina. Persistence of detectable parasitemia was age-independent, or at most, loosely related to age, confirming the pattern observed in 1982. Similarly no significant age-decreasing effect was recorded among seropositive dogs in: a) the probability of detecting parasites in a 2-year follow-up; b) their intensity of infectiousness (=infective force) for T. infestans 3rd-4th instar nymphs, as measured by the percentage of infected bugs observed in each dog xenodiagnosis. Moreover, not only was the infective force of seropositive dogs for bugs approximately constant through lifetime, but it was significantly higher than the one recorded for children in the present survey, and for human people by other researchers. Therefore, and since T. infestans field populations show high feeding frequencies on dogs, the latter are expected to make the greatest contribution to the pool of infected vectors in the rural household of Argentina. This characteristic should be sufficient to involve canine reservoirs definitely as a risk factor for human people residing in the same house. The increased severity of parasitemia observed among dogs in this survey may be related to the acute undernutrition characteristic of canine populations of poor rural areas in our country, which is expected to affect the ability of the host to manage the infection.

A delayed evaluation of two groups of patients with paracoccidioidomycosis was carried out. Both groups were treated with amphotericin B, "but one of them was submitted to maintenance treatment with sulfonamides. Statistical analysis showed that treatment is more effective when patients are maintained with sulfonamide drugs.

O processo de envelhecimento está associado a alterações ao nível da força muscular e do equilíbrio, entre outras. A investigação recente evidenciou a importância da força e estabilidade dos músculos do core para as atividades da vida diária (AVD) em idosos, contribuindo para manter a estabilidade durante a realização dessas atividades. Sendo a funcionalidade e a independência nas AVD a finalidade da fisioterapia, nomeadamente através do aumento da estabilidade postural, parece importante estudar os efeitos da sua intervenção baseada em programas de treino dos músculos do core. Objetivo do estudo - Avaliar o efeito de um programa de exercícios direcionado para os músculos do core no aumento do equilíbrio em idosos.

The population dynamics and the prevalence of chagasic infection of 352 dogs living in 108 rural houses infested by triatomines were studied. The region was divided into three sections according to increasing distances to an urban area. Each animal was identified by means of its particular characteristics and built, and its owners gave information about its habits. By means of xenodiagnosis, serology and ECG studies, prevalences of infection, parasitological-serological correlation, percentage of altered electrocardiographic outlines and percentage of houses with parasitemic dogs, were determined. The rural area showed a characteristic T. cruzi infection pattern and differences in the canine population parameters with respect to the other areas were observed: a higher proportion of puppies than adult dogs, a more sedentary population, higher prevalences of infection, as measured by xenodiagnosis, in dogs, and the highest proportion of bedroom insects infected with T. cruzi. It is assumed that the sedentary characteristics of the human population in that rural area impinge in the blood offer to the triatomine population, and the high percentage of parasitemic dogs of the area, contribute to the rise of "kissing ougs" infected with T. cruzi found in bedrooms.

Com o objetivo de dimensionar a prevalência da infecção pelo Treponema pallidum e determinar fatores de risco relacionados a soropositividade foram rastreados 299 presidiários no Centro Penitenciário de Atividades Industriais de Goiás (CEPAI-GO), 20 Km de Goiânia. O rastreamento sorológico foi realizado utilizando-se como critério de positividade, qualquer resultado sororeagente ao VDRL independentemente do título. Através de um questionário padronizado foram avaliados os seguintes fatores de risco: tempo de encarceramento, sinais e sintomas relativos às principais doenças sexualmente transmissíveis (DST), história de sífilis ou outras DST e práticas sexuais (homo/bissexualismo e número de parceiros). Foram calculados o valor preditivo positivo (VPP) e negativo (VPN) da história pregressa de sífilis obtida na anamnese. Uma soroprevalência global de 18,4% foi obtida, não havendo diferença entre as faixas etárias. O VPP do antecedente de sífilis foi de 26% significando que 74% dos indivíduos que referiram sífilis no passado não tiveram confirmação pelo VDRL. Entre os fatores de risco testados, a bissexualidade foi o único que apresentou associação estatisticamente significante com soropositividade (risco relativo 5,8 - LC 95% 1,2-16,0 p= 0,03). Foram discutidas as dificuldades metodológicas que poderiam ter influenciado nos resultados.

The authors compare the serologic efficacy and the clinical protection afforded by three different measles vaccination schemes in adequately nourished children in São Paulo city, Brazil. Two hundred forty two children were divided into three groups. Group A, comprising 117 children who had received the vaccine before 12 months of age and a second dose at 12 months of age or more. Group B, comprising 46 children who had received only one dose, before 12 months of age. Group C, comprising 79 children who had received only one dose, at 12 months of age or more. The geometric mean titer of antibodies in Group A was 790.1; in Group B, 251.1; and in Group C, 550.3. There was no statistically significant difference between Groups A and C. The exposure to the measles virus was probably similar in all groups, and the children in Groups A and C had similar chances of acquiring the disease after vaccination whereas in Group B the chances were higher when compared to the other two groups. The results obtained in this study favor the use, in developing countries, of a vaccination program against measles that includes an early first dose at eight months of age and revaccination after 12 months of age.

Coccidioidomycosis is a systemic mycosis, endemic in arid areas of the American continent. The rat was employed as an experimental host, since it had been shown to reproduce human lesions and present a chronic course of disease with granulomas mainly restricted to lungs. Given the influence of immunosuppressive therapy on the clinical course of human coccidioidomycosis, we studied the effect of cyclophosphamide (CY) in the experimental rat model. Accordingly, animals were inoculated with 400 Coccidioides immitis arthroconidia of the Acosta strain, by intracardiacal route. As single CY doses failed to alter the course of disease, three schedules were used: A) 4 daily doses of 20 mg/kg each, prior to C. immitis inoculation; B) 4 similar daily doses after infection; and C); 6 doses of 20 mg/kg each, given from day +1 to +4, then on days +8 and +9, post infection (pi), taking day 0 as the time of fungal inoculation. The first two schedules inhibited antibody formation up to day 28 pi, without modifying cellular response to coccidioidin as measured by foodpad swelling. Initially, there was greater fungal spread than in controls receiving C. immitis alone, which proved self-limiting in the latter. In contrast, schedule C led to 559r mortality, with both humoral and cellular response abrogation, accompanied by extensive C. immitis dissemination. Histology disclosed significant alterations, such as the persistence of primary infection sporangia, corresponding to the acute stage of coccidioidomycosis in the absence of granuloma development. Therefore, the observed depression in cellular immunity seems responsible for the lack of inflammatory reaction capable of restricting sporangia proliferation in tissues which, in turn, enhances pathogen spread and mortality rate.

Descobrir o meio significa ter oportunidade de o observar, de o sentir, de o viver, de o experienciar, em suma, de interagir com ele. As crianças pequenas, quando estimuladas a descobrir o meio que as rodeia, desenvolvem um conjunto de competências que lhes permite a construção de imagens sobre o mundo nas suas múltiplas dimensões. O projeto que apresentamos surgiu de um percurso rotineiro pela área envolvente ao Jardim de Infância. Tem a particularidade de se desenvolver em meio rural, num contexto facilitador de experiências vivas e plenas de significado para as crianças. Percorrendo de forma integrada diferentes áreas de conteúdo, mas privilegiando o Conhecimento do Mundo, a Expressão Dramática e o Desenvolvimento Pessoal e Social, este projeto, centrado na descoberta do trator agrícola, procura no meio e na comunidade envolvente os recursos que o fazem crescer e que o tornam tão significativo para as crianças que nele se envolvem: os espaços, onde se constrói e partilha o conhecimento; os profissionais, a quem se colocam todas as questões e onde se procura ajuda para a realização das tarefas mais difíceis; as famílias, com quem se vive diariamente todo o processo.
