Comparative Characterization of the External Genitalia and Reproductive Tubular Organs of Three Species of the Genus Saimiri Voigt, 1831 (Primates: Cebidae).

Morphological information on the reproductive system allows the understanding of ecological and behavioural aspects of different species as well as supports the development of conservational strategies. Unfortunately, for many species, not enough relevant and precise information is available. In the present study, we describe for the first time the macroscopic and histological aspects of female genital organs and external female genitalia of Saimiri macrodon, Saimiri cassiquiarensis and Saimiri vanzolinii. We perform a comparison between these three peripatric species and investigate the possibility of their reproductive morphology to act as a factor of reproductive isolation. We have found that these species share many similarities in most of the analysed organs. Although some important differences were identified that may play an important role in the evolution of the components of the reproductive system of these species, those differences are not enough to compose a mechanism of reproductive isolation for these three species of Saimiri. The results of this study may be used to support the development of biotechnological approaches of reproduction and strategies for conservation programmes and management of threatened species of this genus, particularly S. vanzolinii, considered to be a vulnerable species to extinction.

Heavy metals in tributaries of Pampulha Reservoir, Minas Gerais.

A great amount of heavy metals enter Pampulha Reservoir via it's main tributaries (Sarandi and Ressaca). Although no water quality classification has been carried out for these tributaries, the reservoir is expected to be in class 2 of the CONAMA-86 system. As part of a monitoring scheme of the Pampulha Watershed, heavy metals (Zn, Pb, Cd, Ni, Cu, Cr, Mn and Fe) were investigated in the water at a control site (considered free from direct human influence) and at potential sites of toxicity and contamination during August (dry season) and November (wet season) of 1998. The results for the first sampling period showed relatively high concentrations of zinc (0.22 mg.L-1) in the upper portion of the reservoir. The highest values of nickel and chromium (0.19 and 0.89 mg.L-1, respectively) were found in the initial portion of the Sarandi Stream, while the highest concentrations of lead (0.05 mg.L-1), cadmium (0.014 mg.L-1), manganese (0.43 mg.L-1) and iron (15.25 mg.L-1) were detected in the Ressaca Stream by the landfill dump of Belo Horizonte. A relatively high concentration of cadmium was also detected at the confluence of the two streams. During the second sampling period, there was an increase in the concentrations of zinc at all sampling sites except the control, with values varying from 0.71 mg.L-1 (the Sarandi Stream) to 2.50 mg.L-1 (the Ressaca Stream). Lead, cadmium, nickel and chromium concentrations were also higher in the Ressaca Stream, but not detected at the other sampling sites. Copper values were higher than in the first period: 0.10 mg.L-1 at the control up to 0.38 mg.L-1 at the confluence of the streams. Similar results were found for manganese and iron, with values reaching up to 19.30 and 125 mg.L-1, respectively. Moreover, all values recorded in the second sampling period were much higher than recommended for class 2 waters. These results emphasize the need for such monitoring in relation to better water quality management of this reservoir.

Adiaspiromicose pulmonar disseminada: relato de caso / Disseminated pulmonary adiaspiromycosis: a case report

Relata-se caso de adiaspiromicose causando infiltrado pulmonar retículo-nodular difuso e bilateral, em lavrador de 26 anos. O diagnóstico etiológico foi estabelecido através de biópsia por toracoscopia. Tratado com cetoconazol, o paciente evoluiu bem, retornando às atividades profissionais um mês após a alta.

A case of thoracoscopic lung biopsy proven diffuse human adiaspiromycosis is reported. The patient, a 26-year-old male farm worker presented with a three-week history of fever, sweating, dyspnea and unproductive cough. Radiographic findings were those of granulomatous pulmonary interstitial disease. Treated with ketoconazole he improved very well, resuming work normal activities a month later.

[Prevalence of visceromegalies in necropsies carried out in Triângulo Mineiro from 1954 to 1988]. / Prevalência de megas em necrópsias realizadas no Triângulo Mineiro no período de 1954 a 1988.

One thousand seven hundred and eight chronic chagasic post-mortem examinations studied from a total of 4690 autopsies performed at our Institution. Two hundred and seventy-three chagasic had megas. Megacolon was the most frequent, followed by megaesophagus. Megacolon associated with megaesophagus was the third most common finding. Our data are discussed and compared with the literature. Megacolon and megaesophagus were more prevalent in man, as shown by other workers. Higher parasitemia perhaps could explain this finding.

This is a review of 4.690 necropsies and 24.209 surgical pathology specimens describing the association between megacolon chagasic and malignant tumors of the large bowel. The prevalence of malignant tumors of the large bowel was not higher in megacolon.

[In situ IUD and pregnancy. Follow-up of 27 cases]. / Gravidez e DIU in situ. Evolucao de 27 casos.

PIP: 27 pregnant patients with IUDs in situ were diagnosed in health care centers in Belo Horizonte, MG, Brazil. The pregnancies were followed up and analyses of the complications were carried out in 2 groups. Group A consisted of 15 (55.6%) patients that did not have the IUD removed, and Group B consisted of 12 (44.5%) patients that had the IUD removed before the 12th week of pregnancy. 85.2% of the patients were using the Lippes Loop IUD, varying from 1 to 41 months. 48.1% of the patients were in age group 25-29, and 59.2% had between 2 and 3 children. In group A, 53.3% of the patients had spontaneous abortions, comparing with 8.3% in Group B, and 91.7% of the patients in that group had uncomplicated term deliveries. The results showed a significantly higher abortion rate in patients that did not have the IUD removed. The IUD should be removed as soon as possible when pregnancy is confirmed. If it is not possible, the patient should have careful follow-up.^ieng

Cardiotocografia basal anteparto no Hospital Mater-Dei. Analise dos tracados reativos em 500 exames. / Antepartum basal cardiotocography at the Mater-Dei Hospital. Analysis of reactive tracings in 500 examinations

Sao analisados 500 tracados de cardiotocografia basal realizados no Hospital Mater Dei em 391 pacientes, com uma media de 1,3 exames por paciente.Estas sao provenientes de clinica privada (50,2%) e de servicos diversos (49,8%).Foram considerados no estudo a idade gestacional, paridade e idade das pacientes. Discutem-se a indicacao, os resultados e o tempo decorrido entre o ultimo exame e o parto. Estudou-se tambem retrospectivamente 249 pacientes das quais 213 apresentaram padrao reativo no ultimo exame. Relacionou-se estes tracados reativos com a ocorrencia de natimortalidade, neomortalidade ou recem-nascido com indice de Apgar menor que sete no 5o. minuto, considerando-os falsos-negativos. O indice obtido foi de 1,4%, compativel com dados da literatura

Os fosfolipides no estudo da maturidade pulmonar fetal. Proposta de uma nova rotina. / Phospholipids in the study of fetal lung maturity. Proposal of a new routine

A evolucao dos metodos para avaliacao da maturidade pulmonar fetal tem possibilitado um melhor seguimento das gestacoes de alto risco. A relacao lecitina-esfingomielina e o teste de Clements ocuparam por longo tempo o papel mais importante nesta propedeutica obstetrica. A presenca de um outro fosfolipide, o fosfatidilglicerol (FG), tem sido considerada por nos como o parametro mais importante na avaliacao da maturidade pulmonar fetal. A sua presenca no liquido amniotico nos assegura maturidade em 100% dos casos (ausencia de falso positivo). Ja a sua ausencia esta relacionada com a sindrome de angustia respiratoria em 80% dos casos (um reduzido indice de falso negativo). Importante torna-se ressaltar tambem que o resultado do exame nao sofre alteracoes mesmo na presenca de sangue ou meconio no liquido amniotico. A tecnica usada para a pesquisa do FG e a cromatografia em camada delgada. Assim, os autores propoem uma rotina pratica e mais segura para orientar aqueles casos em que se indica uma interrupcao prematura da prenhez

Cardiotocografia basal (CTB) no posdatismo. / Basal cardiotocography in post-datism

Os autores analisam 54 casos de CTB realizados em gestantes a partir de 42 semanas, relacionando-os com os demais casos atendidos no servico, no periodo de agosto de 1981 ate dezembro de 1982, enfatizando os seguintes parametros: - Apgar dos recemnascidos; - Numero de padroes reativos e nao reativos; - Relacao entre o tipo de parto nesta populacao, em comparacao com a populacao previdenciaria atendida em BH em 1982; - Relacao de desaceleracoes encontradas. Os autores concluem ser a CTB um metodo valido para o acompanhamento da vitabilidade fetal no pos-datismo
