We aimed to determine whether second-trimester abortion using isosorbide mononitrate (IMN) in addition to gemeprost is more effective and reduces side effects compared with gemeprost alone. Study design: Eighty women who were age 13 to 23 weeks' gestation were randomly assigned to receive per vaginam either IMN 40 mg (group 1, 40 women) or placebo (group 2, 40 women) in addition to gemeprost 1 mg up to 3 times daily 3 hours apart for 2 days. Analysis of variance, a χ² test, and a multivariate analysis were performed. Results: Of the 72 women analyzed, 68% (group 1) and 38% (group 2) underwent abortion within day 1 (P < .05). However, group 1 was associated with more headache (18% of women) 3 hours after induction compared to group 2 (0% of women, P = .038). Conclusion: IMN in addition to gemeprost is effective for second-trimester abortion, but is associated with more headache compared with gemeprost alone. [ABSTRACT FROM AUTHOR]

There is little information about the interaction between melatonin, sexual steroids and neuroendocrine system in postmenopausal females, even if former research showed that melatonin is clearly involved in human physiology and pathophysiology. We evaluated the overnight urinary excretion of 6-sulfatoxymelatonin (6-SMT) using a radioimmunoassay in 60 postmenopausal women. The group has been divided into patients with insomnia (10), hyperprolactinemia (7), depression (9), obesity (7) and controls (27). Compared to controls 6-SMT values were significantly higher in depressive females. Patients with hyperprolactinemia showed a trend toward a significantly elevated average nocturnal melatonin concentration. Melatonin levels were significantly lower in patients with insomnia and obese postmenopausal females than in controls. Since previous studies described lower melatonin levels in postmenopausal than in premenopausal women, the indication of melatonin therapy, especially for sleep disorders in this collective, can be handled more generously. Melatonin should be prescribed restrictively in patients with depression and in those with hyperprolactinemia. The role of melatonin in obese females remains unclear. [ABSTRACT FROM AUTHOR]
