Insomnia related to postmenopausal syndrome and hormone replacement therapy: sleep laboratory studies on baseline differences between patients and controls and double-blind, placebo-controlled investigations on the effects of a novel estrogen-progestogen combination (Climodien Ò , Lafamme Ò ) versus estrogen alone

In a double-blind, placebo-controlled study, the antidepressant and vigilance-promoting properties of transdermal oestrogen in post-menopausal depression were investigated utilizing hormonal, syndromal and EEG mapping evaluations. Sixty-nine menopausal women, aged 45-60 years without previous hormonal replacement therapy, diagnosed as major depression without psychotic or suicidal symptoms (DSM-III-R criteria), were randomly assigned to a 3-month treatment with transdermal oestradiol [Estraderm TTS (ETTS) 50 micrograms, applied twice weekly] or placebo. No other psychoactive medication was allowed. After removal of protocol violators, 32 patients were evaluable in each group, which did not differ in age, height or weight. As five patients discontinued prematurely in both groups and in one placebo patient a post-drug EEG could not be obtained, 27 patients remained in the ETTS and 26 in the placebo group for efficacy analysis. While in the placebo group, oestradiol (E2) and follicle stimulating hormone (FSH) remained unchanged, E2 increased and FSH decreased significantly in the ETTS group. Syndromal evaluation showed a significant improvement in the Kupperman Index (KI) as well as Hamilton Depression Rating Scale (HAMD) in both groups, with no inter-group difference. However, EEG mapping demonstrated significant inter-drug differences in brain function, mostly over the left temporal region. While ETTS patients showed an increase of alpha and alpha-adjacent theta activity and a decrease of beta activity, as well as an acceleration of the delta/theta centroid and a slowing of the alpha, beta and total power centroid, no changes occurred in the placebo-treated patients. These neurophysiological findings suggest improvement of vigilance by oestrogen, previously referred to as "mental tonic" effect. There were no changes, however, in the frontal alpha asymmetry index, reflecting left frontal hypo- and right frontal hyperactivation. Thus, this neurophysiological variable represents a state-independent marker for depression. The tolerability of ETTS was very good.

Objective-To define the effects of therapeutic exercise on bone density and back complaints. Methods-A randomised controlled trial with parallel groups was conducted in an outpatient clinic, Medical School, University of Vienna. Ninety two sedentary postmenopausal women with back problems were randomly allocated to either exercise (groups 1 and 2) or control (group 3, no exercise, n=31); the exercise group was retrospectively subdivided into compliant (group 1, n=27) and not fully compliant patients (group 2, n=34). Regular, initially supervised therapeutic exercise aimed at restoring biomechanical function was performed for four years. Bone density in the forearm was measured by single photon absorptiometry at entry and after four years; subjective back complaints were documented. Results-A significant decrease in bone density was observed in groups 2 and 3; no change was noted in group 1; back complaints decreased in group 1 only. Conclusions-Sedentary postmenopausalwomen may benefit from regular long term therapeutic exercise in terms of subjective back complaints and slowed loss of bone mass. (BrJ Sports Med 1996;30:209-212)
