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.

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.

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.

Randomized Controlled Trial Multicenter Study Clinical Trial
Beginning insulin treatment of obese patients with evening 70/30 insulin plus glimepiride versus insulin alone. Glimepiride Combination Group.
This study tested a simple algorithm for beginning insulin for obese patients with type 2 diabetes after sulfonylurea failure, comparing suppertime 70/30 insulin plus continued glimepiride with insulin alone. ⋯ Injection of 70/30 insulin before supper safely restored glycemic control of type 2 diabetes not controlled by glimepiride alone. Control was restored more rapidly and with less injected insulin when glimepiride was continued.

To examine the usefulness of the revised criterion for fasting plasma glucose (FPG) in the diagnosis of diabetes recommended by the American Diabetic Association (ADA) (126 mg/dl, 7 mmol/l), and to characterize insulin response during the 75-g oral glucose tolerance test (OGTT) in newly diagnosed Japanese diabetic subjects. ⋯ The revised ADA criterion for FPG of 126 mg/dl may improve diagnostic sensitivity without loss of specificity in Japanese diabetic subjects when compared with an FPG criterion of 140 mg/dl. Although early insulin secretion was impaired, total insulin secretion did not seem to be reduced in newly diagnosed Japanese diabetic subjects.
