[Visceral leishmaniasis in an infant in Brittany: discussion on the modes of transmission out endemic zones].

The case of a 13 month-old-boy with visceral leishmaniasis acquired in Brittany, a region of France where leishmaniasis is not endemic, is presented. The mode of contamination remains unclear, although a transfusional origin through blood transfusions during the neonatal period appears the most likely.

[Epidemiology of neuroblastoma in Brittany over a 10-year period (1980-1989)].

We report the results of a retrospective epidemiologic study on neuroblastoma in Brittany, a region of France characterized by an homogeneous sedentary population living on a granitic ground. During a period of 10 years (1980-1989), 48 cases of neuroblastoma were observed, which gives an incidence of 7.92 cases per million of children under 15 years.

[Comparative study of results of pH-metry in function of its indication in infants].

A 24 hour pH-metry was performed in children younger than 3 months divided in 4 groups: group 1: 37 infants who presented an apparent life-threatening event (ALTE), group 2: 45 infants with an ALTE and chronic digestive symptoms (recurrent vomiting), group 3: 33 infants with digestive symptoms only, group 4: 32 sudden infant death syndrome (SIDS) siblings. The percent duration of oesophageal pH below 4 (% pH < 4) was measured during 24 hours and 12 nocturnal hours (8 PM-8 AM). In addition the mean duration of nocturnal episodes of reflux (MDNR) was calculated (duration of pH < 4 per 12 nocturnal hours/number of reflux episodes).

[Recurrent fever episodes in an African child: diagnostic difficulties of trypanosomiasis in France].

A young Angolian boy who had emigrated to France at the age of 2, presented with a long history of fever. Gambian Trypanosomiasis was diagnosed with peculiar aspects: 1) evolution of adult sickness with a long hemolymphatic period (first stage) and a subacute worsening period with neurologic deficit and somnolence (second stage); 2) a possible post-transfusional contamination: the young boy, born in South Angola, a nor-highly endemic area, was transfused at the age of 10 months with the blood of a donor who was subsequently treated for Trypanosomiasis; 3) a suppurating adenopathy; 4) a predominance of IgG within the hypergammaglobulinemia while IgM are the predominant immunoglobulins in this affection; 5) a hepatic toxicity of Difluoromethylornithine.
