Paternal age and mental functions of progeny in man.

The effects of maternal age on the quality of offspring are well known. Those due to the father's age are less obvious, apart from the role of increasing paternal age in the onset of many dominant autosomal disorders. But an experimental model has demonstrated that, in rats, increasing paternal age, without any other anomalies, might produce a decreased learning capacity in progeny.

[Malaria in Gabon. Bioclinical survey of non immune Europeans during short stay and prophylactic attitude].

A group of 300 young European adults visiting Gabon for relatively short periods was surveyed monthly for malaria from a parasitological, clinical, immunological, hematological point of view. The regular increase of fevers due to malaria from 1984 to 1988 and the multiplication of cases of amino-4-quinoline resistance in the plasmodial parasites call for new prophylactic considerations for this group residing in this heavily malaria infested area.

[Recurrent familial hyperparathyroidism. A propos of 7 adenomas in 3 members of the same family. Review of the literature].

Over a period of 23 years, 3 members of a family of 5 presented with 7 parathyroid adenomas (4 in the first case, 2 in the second case, 1 in the third case). Excision of each adenoma, with systematic pre-operative assessment of the remaining parathyroid tissue, led to complete clinical and laboratory cure of each episode. The delay in the appearance of recurrence was between 3 and 9 years.
