RESUMO
A group of experts on schistosomiasis and ultrasonography discussed the experiences and results obtained with the Niamey-Belo Horizonte Protocol on Ultrasonography in Schistosomiasis. A series of recommendations about qualitative and quantitative data obtained by ultrasound in studies performed in Africa and Brazil are presented. Immunological, genetic and epidemiological studies must rely on ultrasound for the identification of patients with periportal thickening/fibrosis.

Patient with autoimmune haemolytic anaemia and thrombocytopenic purpura (Evans Syndrome), treated with immunosuppressive therapy (prednisone and azathioprine) developed brain abscess unresponsive to antimicrobial therapy, in spite of its 23 days duration. Diagnosis could be possible after recover secretion of peribulbar abscess and maintenance of this material over seven days in incubation.

Reports on abdominal ultrasound studies in patients with acute schistosomiasis are still scarce and limited data are available on structural changes of the liver parenchyma in this stage of the disease. 26 patients with acute schistosomiasis mansoni were submitted to clinical and ultrasound examination. For ultrasound comparison, each acute patient was paired by age, gender, weight and height to a non-infected individual. Ultrasound showed a non-specific homogeneous size increase of the liver, and spleen in all acute patients, and easily identified intraabdominal lymph nodes in the periportal region in most cases. Three out of the five patients with periportal thickening underwent percutaneous liver biopsy. Periportal thickening disappeared 6 months after treatment for schistosomiasis. 24 months after successful treatment there was involution of the liver and spleen; lymph nodes, although reduced in size, were still easily recognized. Liver biopsy showed dense inflammatory infiltration of neutrophils, macrophages and eosinophils in the portal tracts associated with discrete fibrous tissue formation.

This paper reports reduction on the reproductive capacity of female mice infected with Schistosoma mansoni, either in the acute phase or in the chronic one of the disease. This decrease in the reproductive capacity was highly significant (93.3% and 86.7%, for the acute and chronic phases, respectively).

Este trabalho trata de redução na capacidade reprodutiva de camundongos fêmeas infectados com Schistosoma mansoni, tanto na fase aguda como na fase crônica da doença. Esta diminuição da capacidade reprodutiva foi altamente significativa, com índices de 93,3% e 86,7% nas fases aguda e crônica, respectivamente.

The cases of five patients with unusual manifestation of acute schistosomiasis mansoni are described in this paper. One patient developed skin lesions, three displayed diverse lung involvement, and one presented pyrogenic liver abscesses caused by Staphylococcus aureus.
