APUD-like cells in the primitive gut of a 27 day old human embryo.

A 27 +/- 1 days old human embryo arising from an ectopic pregnancy was incubated with 3,4, L-dihydroxyphenylalanine (L-DOPA) to investigate whether cells of the gut primordium have at this early stage of development, the ability to take up the amine precursors. We could observe that a few cells exhibiting greenish fluorescence were located in the epithelium wall of the fore gut. Most of them were situated in contact with the basal lamina and possessed a long apical process extending over towards the gut lumen.

[Prenatal diagnosis of pulmonary hypoplasia camptodactyly syndrome. Hypothesis concerning the origin of hydramnios].

Camptodactyly and pulmonary hypoplasia syndrome was described for the first time in 1974. Today 15 cases have been found. None were subject to a prenatal diagnosis as any ultrasonography.

[Cesarean section preceding the 34th week of amenorrhea: maternal and fetal repercussions at the western university hospitals. Regional survey or 383 cesarean sections and 436 newborn infants out of 86,116 births in 5 years].

This statistical enquiry carried out in a region of France by the University Hospital Services in Obstetrics and voluntarily devoid of bibliographical references, deals with a group that are particularly pathological and thus probably explains the seriousness of the prognosis for the newborn and the frequency of maternal morbidity following these early operations. 15% of serious maternal complications with severe neonatal pathology which was often heavy and responsible for the death of the fetus in 22.4% of the cases and the late sequelae in the newborn in more than 10% of cases, mad it important to seek for the inevitable link between the pathology and the length of gestation at the time of the operation.
