[Risks of sudden death in siblings].

The risk of sudden infant death among siblings has long been overestimated: in all epidemiological studies the risk of recurrence remains at 1% or below, thereby excluding a hereditary hazard. Compared with the general population, the risk is increased in only a small percentage of families which can be detected (familial gastrooesophageal reflux or vagal hyperreflexibility, psychosocial problems and, more rarely, hereditary pathology). In the vast majority of families the relative risk is not objectively augmented.

[Sudden newborn infant death in maternity. Anatomo-clinical study of 31 cases].

Patients And Methods: All cases of sudden and unexpected death occurring in maternity were studied over a period of 6 years (1985-1991). Anamnestic data, results of clinical examination of the body and findings of bacterial screening of body fluids or tissues were collected. The results at necropsy were also collected following the protocol used, with parental consent, in all cases of sudden infant death syndrome.

[Future of premature infants of less than 33 weeks gestational age: results of an inquiry undertaken in 1985 in the Paris region].

Improvements in combining obstetrics and neonatology led to a trend to intervene earlier in premature babies born before the 33rd week of gestational age. The enquiry that was carried out in 1985 in the Paris geographical region had as its objective to assess on the one part how many premature deliveries occurred between the 25th and 33rd week of amenorrhea and on the other hand what happened in the short term to the infants born from these pregnancies, i.e.
