[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.
