Glucose-6-phosphate dehydrogenase and hemoglobin variants in Kel Kummer Tuareg and related groups. Indirect evidence for alpha-thalassemia trait.

A field study of glucose-6-phosphate dehydrogenase (G6PD) and hemoglobin polymorphisms was performed in 327 subjects belonging to the Kel Kummer, a highly inbred Tuareg tribe of North-East Mali, and to the contact populations. In the Kel Kummer group 11% of the investigated subjects carried the nondeficient G6PD A+ variant. No other G6PD variant was found. Hemoglobin D Ouled-Rabah was found in 21% of the subjects of this group. The presence of an alpha-thalassemic trait was also inferred from indirect evidence. The contact groups (Inedän, Iklan, Kel es Suq and Dausahaq) exhibited different polymorphisms at the G6PD and globin loci, substantiating their belonging to different ethnic stock.

[Sarcoidosis and Whipple's disease. Association? Relation?].

On the basis of a personal case in which two successive diagnoses of sarcoidosis and Whipple's disease were made at an interval of four years, the authors discuss the possible association or relationship between these two disorders, both diffuse, affecting the reticulo-histiocytic system and diagnosed on a histological basis. Review in the literature of 54 cases of Whipple's disease with pleuro-pulmonary lesions makes it possible on the one hand to associate with the latter numerous examples of extra-intestinal involvement, the histological appearance of which of a non-specific epithelioid granuloma does not indicate the diagnosis during the long pre-intestinal phase, and on the other hand to explain that during this period, the presence of pleuro-pulmonary lesions leads to an initial diagnosis of the probability of sarcoidosis. The practical consequences are as follows: The appearance of intestinal signs during "sarcoidosis" should lead to intestinal or mesenteric node biopsy to seek the macrophages with highly PAS positive cytoplasm characteristic of Whipple's disease. Their discovery necessitats long term antibiotic therapy which has recently transformed the outlook in this disease, invariably fatal in the past.

[Acute obstruction of the esophagus by mucilage].

The authors present the case of an 84 year-old woman with chronic constipation who suddenly developed acute obstruction of the lower oesophagus on taking a tablespoonful of mucilage without water. The obstruction was relieved by fiber endoscopy. There was no other previous lesion which might explain this complication. The patient was seen again later in good general health. The authors recall the clinical and radiological signs of acute obstruction of the oesophagus and discuss the physiopathology. They propose treating them exclusively by oesophageal fiber endoscopy.
