[Calcified and suppurated epidermoid cyst of the spleen (author's transl)].

Reporting a case of epidermoid cyst of the spleen revealed on suppuration brings the authors to review the classification of epidermoid cyst. These are benign tumors in the main present clinically with left hypochondrium pain and the possibility to palpate a splenomegaly or mass in this hypochondrium. The diagnostic approach includes diverse investigations, in particular a series of radiological examinations; surgical intervention will confirm and avoid complications.

[One hundred and twenty-three cases of sickle-cell trait (author's transl)].

One hundred and twenty-three cases of sickle-cell trait (122 negro immigrants) are studied in a department of internal medicine. The frequencies of G6PD deficiency, anemia, splenomegaly and tuberculosis are neighbouring at the negro without hemoglobinopathy. The relationship between the sickle-cell trait and the reason of admission of the final diagnosis il likely in 2,4 % of the cases, doubtfully in 15,4 %, null in the other cases. The occasional (hemolytic, thrombotic, painful, visceral, osseous) manifestations of the sickle-cell trait (apart from the constant hyposthenuria) and their mechanism are summarized and discussed.

[Osseous manifestations and hemoglobinopathies C (author's transl)].

The authors report two cases of hemoglobin C trait and hemoglobin C disease with bone tuberculosis and, in the first case, bone infarction of one condyle two years after the tuberculosis of the other knee. This suggests the possibility of osseous manifestations in the course of hemoglobin C trait or hemoglobin C disease apart from hemoglobin SC disease.

[Osseous manifestations of treponematoses : six cases in immigrated black African (author's transl)].

The authors report the cases of six immigrated Black Africans with clinical and radiological (4 cases with condensing osteitis ; 2 cases with condensing forms and multiple lacunae) bone manifestations ; these manifestations, the serological tests and the osseous biopsy (three cases out of four) are consistent with the diagnosis of bone syphilis. These facts are discussed and ascribed to tertiary syphilis rather than to congenital or secondary syphilis, to yaws or endemic syphilis.

[152 cases of tuberculosis in African Negro immigrants in a Parisian service of internal medicine (author's transl)].

This study of 152 cases of tuberculosis in African Negro immigrants seen between 1972 and 1976 showed the predominance of especially pulmonary respiratory lesions and/or hilar ganglio-mediastinal lesions. The other lesions are frequent, i.e. the lesions of lymph nodes, bones, peritoneum, liver, pericardium ; the multiple lesions are likewise frequent. Smears and culture of sputum and/or biopsy of organs or tissues such as pleura, lymph node, liver and peritoneum are the diagnostic procedures. In spite of frequent resistance, treatment with isoniazid, rifampicin and ethambutol gave good results in high risk subjects, who are almost always allergic on arrival in France.

[Comparative value of parasitological and immunological investigations in the diagnosis of chronic schistosomiasis].

Two group of patients including 63 urinary schistosomiasis and 49 intestinal schistosomiasis were studied with the following investigations: microscopic examination of stools and urines, rectal mucosae biopsy, total IgE dosages, plasmatic proteins values and indirect immunofluorescence. The data obtained led to the following conclusions: --Recovery must be based on the microscopic observation of stools and/or urines and R. M. B. --I. F. I. and IgE dosages alone were not sufficient. --Protides evaluations (IgA, IgG, IgM, orosomucoid, haptoglobin) did not show any informative values and did not seem to be linked with the parasitologic disease.
