Prevalence of minor congenital anomalies in newborns of diabetic mothers.

Minor congenital anomalies (MCA) were assessed in the offspring of 802 gestational diabetic mothers, 117 pre-gestational diabetic mothers, and 380 offspring born to normal mothers. The prevalence of infants with MCA ranged between 19.4% and 20.5% in the three groups without any significant difference between them. There was no correlation between the prevalence and type of MCA and the severity of the diabetic state. Neither was there any correlation between the prevalence or type of MCA and the appearance or type of major congenital anomalies.

The protracted effect of o,p'-DDD in Cushing's disease and its impact on adrenal morphogenesis of young human embryo.

We hereby present a patient with Cushing's disease who became pregnant while being treated with o,p'-DDD and underwent a therapeutic abortion in view of the known embryotoxicity and placental transfer of this drug. Biopsy of adipose tissue in this patient showed it to be the storage site of considerable quantities of o,p'-DDD. Serum levels of o,p'-DDD determined in this patient initially four months after withdrawal of treatment and in another similar case three months after withdrawal were about 20 times higher than those found in untreated patients and reached control values only about 20 months later. Repeated evaluation of plasma and urinary free cortisol failed to reveal any correlation with the serum levels of o,p'-DDD, suggesting that the drug blood values cannot be used as a reliable indicator of the therapeutic effect on the adrenal gland. The histopathological examination of the embryo, aged about 42 days, revealed a dysmorphogenic event in the cortical primordia characterized by pycnotic sympathoblasts. It is suggested that such a toxic effect of o,p'-DDD on the embryonic cortical cells may act indirectly, affecting the viability of the migrating sympathoblasts.

Prevalence of diabetes in Israel. Epidemiologic survey.

A survey of 4660 Israeli adults aged 30-65 yr revealed an overall diabetes prevalence of 4.1%. Prevalence was slightly lower in women (3.5%) than in men (4.3%), rose with age, and was highest in the group greater than 60 yr old (10.3%). In approximately 40% of the diabetic subjects, the diagnosis of diabetes was made as a result of the screening program. Association with a family history of diabetes, obesity, and the presence of other diseases was greater in diabetic than in nondiabetic subjects. The prevalence of diabetes differed among different segments of the survey population when classified according to country of origin, being lowest in African and Asian (1.2%), intermediate in American and European (4.9%), and highest in Israeli born (5.5%); this order of prevalence is the reverse of that reported in earlier surveys. The results indicate that the overall diabetes prevalence in Israel, and that within the European- and American-born segment, is comparable to that reported in other westernized societies. The findings also suggest that environmental factors contribute to the phenotypic expression of the non-insulin-dependent genotype(s) but that the influence of such factors varies with different genetic backgrounds.

High prevalence of diabetes in young adult Ethiopian immigrants to Israel.

We performed oral glucose tolerance tests in 158 Ethiopian immigrants to Israel. The subjects were less than 30 yr of age, had lived in Israel less than or equal to 4 yr, and originated from villages in the Gondar and Ambovar regions of Ethiopia. Most had been subjected to famine conditions in Ethiopia and/or extreme hardship in Sudan before or during immigration. All were lean. They revealed a profound change in dietary habits since their arrival in Israel, with consumption of large amounts of refined carbohydrate in place of spicy stews and injura (Ethiopian pita) that had constituted dietary staples in better times in Ethiopia. According to National Diabetes Data Group criteria, 14 (8.9%) of the subjects had diabetes, and another 14 (8.9%) had impaired glucose tolerance. In addition, 13 subjects had a dramatic increase in capillary blood glucose levels (greater than 300 mg/dl) 1 h after ingestion of 75 g glucose, despite fasting and 2-h values well within the normal range, and they complained of associated symptoms during the 1st h of testing. Eleven of 137 men and 3 of 21 women had diabetes; 7 (5.1%) of the men and 7 (33%) of the women had impaired glucose tolerance. These results indicate a high prevalence of diabetes among young adult Ethiopian immigrants of relatively short residency in Israel, for which the factors responsible warrant further investigation.

Glucose tolerance test in Israeli pregnant women.

An oral glucose tolerance test (GTT) was performed in 1,055 healthy Israeli women at various stages of pregnancy. The whole venous blood glucose levels were higher in Israeli pregnant women than in American pregnant women. By adding 2 SD to the mean values, the upper limits of the oral GTT in the Israeli pregnant women were higher than the corresponding limits in American pregnant women. According to our results, 2.7% of Israeli pregnant women have gestational diabetes. However, if American standards are used, then 3.7% of our population would be considered to have gestational diabetes. Each population should be evaluated, therefore, according to its specific standards. The mean +/- 2 SD glucose levels of the GTT in pregnant women at age greater than or equal to 30 years were higher than those of the entire population of pregnant women. It is suggested, therefore, that the GTT of each pregnant woman should be considered according to her age-group.

Prevalence of congenital anomalies and neonatal complications in the offspring of diabetic mothers in Israel.

The prevalence of diabetes in pregnancy and its fetal and perinatal consequences in a large population of Israeli pregnant women during the last decade are presented. The study population consisted of 878 gestational diabetic women, 132 pre-gestational diabetic women, and 380 healthy pregnant women who served as controls. Minor congenital anomalies ranging between 19.4 and 20.5%, major congenital anomalies between 1.80 and 6.82%, and neonatal complications, such as macrosomia (5.6-25.0%), hypoglycemia (0.9-7.8%), hyperbilirubinemia (8.2-16.7%), hypocalcemia (2.7-5.5%) and polycythemia (3.8-13.3%), were observed in the study population. Despite meticulous maternal glucose control, we could not entirely eliminate fetal and neonatal complications. The definition of the normal and abnormal fetal intrauterine metabolic environment remains to be elucidated.
