[A new case of hydatidiform mole occurring on one of the ova of a twin pregnancy].

The authors report here a new case of hydatid mole in one of the eggs of a mole pregnancy. 48 other cases have been reported in 13 publications. The birth of a viable, well-developed fetus is described in 13 instances (27%), fetal death in utero in 22 instances (46%), birth of a non-viable fetus 11 times (23%) and malignant degeneration twice (4%).

[Evaluation of the economic burden in the respective indications of in vitro fertilization and tubal microsurgery at a regional hospital center].

The authors have calculated the cost of obtaining and maintaining an intrauterine pregnancy to term by IVF and by tubal surgery according to the four classical indications. They have worked this out from local experience. The indications are: reversal of sterilization, surgery on proximal lesions, surgery on distal lesions and multifocal lesions.

[Triploidy].

Using their own experience which they described in 1984 and reviewing as well the literature of the condition since that time has led the authors to suggest that triploidy should be considered as a pathological entity with three clinical forms: early abortion, mid-trimester termination and the birth of triploidy fetuses either alive or dead. They discuss the clinical features, the ultrasound appearances, the pathological and anatomical details and the cytogenetics of triploidy. They differentiate this condition from trophoblast disease and from the central hydropic conditions which occur with normal caryotypes.
