OBJECTIVE-To evaluate the incidence and predisposing factors of severe hypoglycemia (SH) in pregnant women with insulin-dependent (type I) diabetes mellitus.RESEARCH DESIGN AND METHODS-SH (impairment of consciousness due to hypoglycemia subsequently treated with glucagon or i.v. glucose) was recorded in all pregnant type I diabetic women (n = 77) who attended our pregnancy clinic during 85 pregnancies from 1986 to 1990.RESULTS-Ninety-four SHs were reported during 35 pregnancies. Of 94 SHs, 84% occurred before the 20th gestational wk (median 12th wk) and 77% during sleep. In the group with SH, there was no permanent maternal sequelae, and there was a favorable fetal outcome (no perinatal death and no congenital malformation). Mean HbA lc values were not different between the group with and without SH for the first half (6.4 ± 1.1 vs. 6.3 ± 0.9%) and 2nd half (5.4 ± 0.6 vs. 5.5 ± 0.7%) of pregnancy. The percentage of women with SH before pregnancy (51 vs. 28%, P < 0.05) and the incidence of SH patients before pregnancy (0.49 vs. 0.08 SH/ patient/yr) was different between the group with and without SH.CONCLUSIONS-SH is frequent during pregnancies of type 1 diabetic women with near normoglycemia. The risk for SH is particularly pronounced during the first half of pregnancy and in women with a history of SH.
In order to improve the basis upon which to advise women with diabetic nephropathy about pregnancy, we studied the effect of diabetic nephropathy on the course of pregnancy, perinatal outcome, infant development and long-term outcome of the mothers. All pregnancies of women with diabetic nephropathy (defined as proteinuria > 400 mg/day (n = 26), creatinine clearance < 80 ml/min and hypertension in the first trimester (n = 10)) followed at our centre from 1982 to 1992 were identified (34 White class F and 2 White class T) and the women and their children re-examined in the spring 1993. From the first to the third trimester the percentage of women with proteinuria over 3 g/day increased from 14 to 53% and those treated with antihypertensive medication from 53 to 97%. There were no intrauterine or perinatal deaths, but one child died suddenly 4 weeks postpartum. Of 36 newborns (gestational week at birth 36(3), birth weight 2384(834) g)), 11 were born before week 34 and 8 had respiratory distress syndrome. Renal function in the first trimester, diastolic blood pressure in the third trimester and an HbA1c above normal were predictive of gestational age at delivery and low birth weight (stepwise regression analysis). At follow up of the children (n = 35, age 4.5 (0.4-10) years) the majority (n = 27) were normally developed but seven had psychomotor retardation (four of them major). One child had a severe motor retardation due to a congenital anomaly. At follow up, 21 of the 29 mothers had preserved renal function (creatinine 1.3 (0.8-4.3) mg/dl and 8 had developed end stage renal disease and required dialysis (2 of whom were White class T) within 3 (1-9) years postpartum.(ABSTRACT TRUNCATED AT 250 WORDS)
Unrestrained weight-bearing of injured foot bones and joints of more than 400 kg x week (equivalent to 8 weeks of normal walking by a person of 50 kg body weight) prompts Charcot deformities, with disintegration of the Lisfranc joint. Early off-loading by TCC treatment allows healing without deformities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
