Two hundred thirty subjects with insulin-dependent diabetes were followed up longitudinally by measuring glycohemoglobin values to relate glucose control with renal and retinal complications. Subjects with long-term poor control (glycohemoglobin values greater than 1.5 times the upper limit of normal) had 3.6 times the prevalence of microalbuminuria and 2.5 times the prevalence of level 3 to 6 retinopathy than that found in subjects with long-term good control (glycohemoglobin values within 1.33 times the upper limit of normal). ⋯ No subject whose mean glycohemoglobin value was consistently within 1.1 times the upper limit of normal had retinopathy or microalbuminuria. In contrast, when the mean glycohemoglobin value was more than 1.5 times the upper limit of normal, 24 (29%) of 82 subjects had microalbuminuria and 30 (37%) of 82 had level 3 to 6 retinopathy.

Review Case Reports
Should hyperbaric oxygen be used to treat the pregnant patient for acute carbon monoxide poisoning? A case report and literature review.
Carbon monoxide (CO) is the leading cause of death due to poisoning. Although uncommon, CO poisoning does occur during pregnancy and can result in fetal mortality and neurological malformations in fetuses who survive to term. ⋯ A case is presented of acute CO poisoning during pregnancy that was successfully treated with HBO. Recommendations are suggested for the use of HBO during pregnancy.
