Fetal and placental effects of insulin therapy on pregnancy of diabetic rats were studied. Alloxan was administered intravenously at the dose of 42 mg/kg of body weight. Five experimental groups were formed: control (G1, n=12), non-treated rats with moderate diabetes (G2, n=10), insulin-treated rats with moderate diabetes (G3, n=11),non-treated rats with severe diabetes (G4, n=12) and insulin-treated rats with severe diabetes (G5, n=10). Six hundred and thirty-four newborn rats and placentas wereprocured. The perinatal result of insulin therapy was directly related to the quality of glycemia control. Thus, inadequate control of moderate diabetes produced levels of moderate hyperglycemia, did not interfere with the newborn rats' body weight and decreased the proportion of LGA newborn rats. Adequate control of severe diabetes brought the newborn rat glycemia to normal levels, increased the newborn rats' body weight and decreased the proportion of SGA newborn rats. Adequate insulin therapy for severe diabetes diminished the weight of the placentas, but did not change the placental index.

HELLP syndrome is a severe complication of preeclampsia that increases maternal and perinatal morbidity and mortality. Two cases of recurrent HELLP syndrome are described, maternal death occurring in one of the cases. This study is a warning about the increased risk of HELLP syndrome in the next pregnancy.

Purpose: to determine the most efficient clinical and histopathological predictors of complete hydatidiform mole (CHM) after gestational trophoblastic tumors (GTT). Methods: a prospective clinical and histopathological study was performed on all patients with CHM treated at the University Hospital of Botucatu between 1990 and 1998. Preevacuation clinical evaluation allowed the classification of molar pregnancy into high risk and low risk CHM. The author analyzed the clinical predictors of GTT established by Goldstein et al.¹ and by other authors2--10. The histopathological evaluation included the confirmation of CHM diagnosis based on the criteria by Szulman and Surti11 and the understanding of risk factors for GTT by Ayhan et al.8. The clinical and histopathological predictors were correlated with the postmolar GTT. Results: ovarian cysts larger than 6 cm and uterus size larger than 16 cm were the most efficient clinical predictors of GTT in 65 patients with CHM. Trophoblastic proliferation, nuclear atypia, necrosis/hemorrhage, trophoblastic maturation, and the ratio cytotrophoblast to syncytiotrophoblast were not significant predictors of GTT. The correlation between the clinical and histopathological predictors for the development of GTT was not possible, as no histopathological parameter was significant. Conclusion: additional investigations could evaluate other predictors for persistent disease, and its usefulness in a clinical context. The sequential determination of plasmatic beta-hCG remains the only safe predictor for persistent disease.
