Successful pregnancy in a woman with lipoatrophic diabetes mellitus. A case report.

BACKGROUND: Lipoatrophic diabetes mellitus is a rare insulin-resistance syndrome. A successful pregnancy occurred in a woman with lipoatrophic diabetes with no antepartum or intrapartum complications except hypertriglyceridemia, treated with gemfibrozil. CASE: A 29-year-old primigravida had lipoatrophic diabetes most consistent with congenital partial lipodystrophy (Kobberling-Dunnigan syndrome). The antenatal course was remarkable only for a midtrimester rise in serum triglycerides. The patient underwent oxytocin induction and an uncomplicated vaginal delivery. CONCLUSION: This case demonstrates that women with lipoatrophic diabetes who are otherwise healthy should not be discouraged from trying to conceive. Blood lipids should be checked periodically and hypertriglyceridemia treated to prevent pancreatitis. Gemfibrozil was used in this patient without apparent adverse effects.

Effects of fluoxetine or D-fenfluramine on serotonin release from, and levels in, rat frontal cortex.

Using in vivo microdialysis of frontal cortex in anesthetized rats, as well as analysis of frontal cortex homogenates, we examined the effects of chronic administration of fluoxetine (30 mg/kg, i.p.) or D-fenfluramine (7.5 mg/kg, i.p.), administered daily for 3 days, on serotonin and 5-HIAA levels a day later. Measurements were also taken after 3-, 7- , and 21-day recovery periods. Neither chronic fluoxetine nor D-fenfluramine changed basal serotonin release. Both treatments, however, transiently decreased the release of serotonin evoked by an acute dose of D-fenfluramine (10 mg/kg, i.p.). Release initially was completely suppressed in fluoxetine-pretreated animals but returned to normal by the 21st day of washout; following D-fenfluramine pretreatment, normal release was attained by the 7th day of washout. Both fluoxetine and D-fenfluramine transiently decreased 5-HIAA levels in the dialysates and tissues. Both drugs also caused prolonged changes in frontal cortex serotonin levels, D-fenfluramine lowering them but fluoxetine elevating them. These results suggest that, at comparable dosage levels relative to their ED50s, fluoxetine and D-fenfluramine cause comparable reversible effects on brain serotonin release. The drugs also cause prolonged but opposite changes in brain serotonin levels, probably reflecting differences in the extents to which they or their principal metabolites release serotonin and block its reuptake.
