In this study, we assessed maternal-fetal outcomes in untreated patients with increasing carbohydrate intolerance not meeting the current criteria for the diagnosis of gestational diabetes mellitus (GDM), examined the relationship between birth weight and mode of delivery among women with untreated borderline GDM, treated overt GDM, and normoglycemia, and established more efficient screening strategies for detection of GDM. This was a prospective analytic cohort study in which nondiabetic women aged > or = 24 years were eligible for enrollment. A 50-g glucose challenge test (GCT) and a 100-g oral glucose tolerance test (OGTT) were administered at 26 and 28 weeks gestational age, respectively. ⋯ Recognition of GDM may lead to a lower threshold for surgical delivery. The efficiency of screening for GDM can be enhanced by adjusting the current GCT threshold of 7.8 mmol/l to new values related to time since the last meal before screening. Further analyses are underway to elucidate whether maternal risk factors can be used to achieve additional efficiency gains in screening.

Comparative Study
Combined use of a fasting plasma glucose concentration and HbA1c or fructosamine predicts the likelihood of having diabetes in high-risk subjects.
To assess the validity of using fasting plasma glucose (FPG) concentrations in conjunction with HbA1c or fructosamine for the screening of diabetes in high-risk individuals. ⋯ The paired values of FPG and HbA1c or FPG and fructosamine helped to identify potentially diabetic subjects, the diagnosis of which could be further confirmed by the 75-g OGTT. Using this approach approximately 80% of OGTTs could have been saved, depending on the diagnostic cutoff value of FPG.

Randomized Controlled Trial Comparative Study Clinical Trial
Diabetic peripheral neuropathy. Effectiveness of electrotherapy and amitriptyline for symptomatic relief.
To evaluate the efficacy of combining electrotherapy with amitriptyline for the management of chronic painful peripheral neuropathy in patients with type 2 diabetes. ⋯ Our clinical observations suggest that transcutaneous electrotherapy is effective in reducing the pain associated with peripheral neuropathy. This form of therapy may be a useful adjunctive modality when it is combined with a pharmacological agent, such as amitriptyline, to augment symptomatic relief.

We sought to determine whether strict glycemic control during diabetic pregnancy combined with elective early induction of labor reduces the rate of cesarean delivery and fetal birth trauma. We used a population-based longitudinal design covering three periods corresponding to changes in the management protocol for diabetic pregnancy at our center: 1) 1980-1989: no set level of maternal glycemia, elective cesarean section when estimated fetal weight was 4,500 g or more, and no elective early induction; 2) 1990-1992: desired mean maternal glycemia < or = 5.8 mmol/l, elective cesarean section when estimated fetal weight was 4,000 g or more, and elective early induction at 40 weeks for large-for-gestational-age fetuses; 3) 1993-1995: desired mean maternal glycemia < or = 5.3 mmol/l, elective cesarean section when estimated fetal weight was 4,000 g or more, and elective early induction at 38 weeks for large-for-gestational-age fetuses. ⋯ There was a gradual, constant, and significant decline in the incidence of macrosomia (17.9, 14.9, and 8.8%, respectively; P < 0.05) and large-for-gestational-age fetuses (23.6, 21.0, and 11.7%; P < 0.05) coupled with a gradual, nonsignificant decrease in cesarean deliveries (20.6, 18.4, and 16.2%) and in cases of shoulder dystocia (1.5, 1.2, and 0.6%), to rates close to those of the normal population. Our data show that maintaining strict control of maternal diabetes and adhering to an active management protocol for early elective delivery based on the estimated fetal weight have a significant effect on reducing the rate of macrosomia, thereby affecting the incidence of both traumatic births and cesarean deliveries.
