[Multiple digestive involvement in visceral leishmaniasis in a patient with HIV infection: favourable course with itraconazole].

We report a case of visceral leishmaniasis due to Leishmania infantum in a 35 year-old patient with acquired immunodeficiency syndrome who complained of chronic diarrhea. Biopsy specimens of gastric and duodenal mucosa and bone marrow aspirate led to the diagnosis. Enterocytozoon bieneusi, fortuitously found in the duodenal mucosa, did not seem to be the causative agent of diarrhea in this case, but its association with visceral leishmaniasis is rare.

[Age and fertility: value of endometrial co-cultures].

Embryo coculture system may contribute to understand the mechanisms underlying the decrease of fertility with aging. We report here our experience of coculture on maternal endometrial cells and histology of endometrial biopsy in 90 patients with repeated failures of implantation. Histology dating failed to find any age related changes.

Coculture of embryos on homologous endometrial cells in patients with repeated failures of implantation.

Objective: To evaluate the value of coculture of embryos on endometrial cells in patients with repeated failures of implantation.

Design: A retrospective comparison of pregnancy rates between IVF-ET with coculture and standard culture methods.

Patients: Ninety patients with repeated failures of transfer (range 4 to 11) underwent IVF-ET for a variety of disorders.

[Frequency of germ isolation from urinary infections in community practice; their sensitivity to 7 antibiotics including a combination of amoxicillin and clavulanic acid. Evaluation on 1611 samples].

A multicenter study including 10 outpatient private laboratories (hospital laboratories excluded) was carried out in France. 1,611 urines samples from patients with UTI were collected during the forth trimester of 1987. The most frequently recovered pathogens were: E.

[Peritoneal gliomatosis associated with a mature teratoma of the ovary].

Peritoneal or/and omental implants composed of mature glial tissue is a rare complication of ovarian teratomas. A few cases have been previously reported, and one more case is described. The glial nature of the implants is proved by the presence of glial fibrillary acidic protein.

[Baso- and spinocellular Pinkus fibroepithelial tumor].

A seventy-eight-year-old man presented with a moist proliferating tumor of the back which arose six months earlier amidst numerous verrucae seborrheic. The tumor's size was 20 X 28 mm. Two different aspects were found upon histologic examination.

[Histo-pathological features of African mycetomas (author's transl)].

From a review of 94 original cases of mycetoma, a description of the most important histo-pathological features of these tumors is given. The microscopic diagnosis of mycetoma is easy and so is generally the identification of the responsible agent, either a bacteria or a fungus. In every case and specially in atypic ones a mycological study is necessary to ascertain the aetiological diagnosis.

[Bases for control of arthropod vectors: III--Insecticides and questions they raise (author's transl)].

Insecticides are still nowadays our main way of control of arthropod vectors. Their use raises many important question, resistance of the vectors, toxicity, risks of pollution and costs of spraying campaigns. These various drawbacks are considered with special regard to the problem of resistance its world wide spreading, its mechanisms, its meaning.

[Bases for control of arthropod vectors: I--Definitions, bioecology of vectors (author's transl)].

Arthropoda form the most diversified and multitudinous phyllum of the animal kingdom. In this "arthropod world", the authors give the respective position of the arthropoda: a) detrimental to crops, b) venomous and noxious for human being, but mainly those who are vectors of human diseases, say about a hundred species. Biological, ecological and environmental main features of the most important arthropod vectors of human tropical diseases are reviewed.
