Randomized Controlled Trial Comparative Study Clinical TrialCyproterone acetate versus levonorgestrel combined with ethinyl estradiol in the treatment of acne. Results of a multicenter study.
In spite of an abundant literature on antiandrogen treatment with cyproterone acetate (CA) there have been no objectively measured results to prove statistically the possible superiority of CA over combined oral contraceptive pills in the treatment of acne vulgaris. A multicenter study was therefore done, in which two preparations containing CA in combination with ethinylestradiol (EE) were compared with a marketed combined oral contraceptive pill. The preparations studied were: CA 2 mg + EE 50 micrograms (Diane), CA 2 mg + EE 35 micrograms (Diane mite), Levonorgestrel 150 micrograms + EE 30 micrograms (Neovletta). ⋯ The groups thus constituted were of similar size and comparable with regard to age, degree of acne, and menstrual and contraceptive histories. As the number of acne lesions varied considerably between patients all data were converted into percentage change during treatment before they were processed in a computer. After only 4 months of treatment the patients on Diane and Diane mite had a significantly greater reduction in the number of acne lesions compared with those on Neovletta.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical TrialA comparative study of uterine activity and fetal heart rate pattern in labor induced with oral prostaglandin E2 or oxytocin.
Labor was induced for medical reasons at or near term in altogether 200 patients. The women were randomly assigned to low amniotomy and either oral PGE2 or intravenous infusion of oxytocin. The initial PGE2 dose was 0.5 mg, followed by 1.0 mg every hour for up to 24 hours. ⋯ One period of hypertonus was observed in one patient treated with PGE2 but it was not associated with alterations in FHR and disappeared without additional therapy. Both mild and more severe variations in FHR occurred but were equally common on both treatment groups. There was no perinatal mortality among the newborns and the Apgar score 5 minutes after delivery was 8 or more.

Randomized Controlled Trial Clinical TrialClinical experience of naproxen in the treatment of primary dysmenorrhea.
The effect of naproxen, Naprosyn, Syntex, in treatment of primary dysmenorrhea was studied in a double-blind, randomized, placebo controlled multicenter study. Nintyseven women, aged between 18--40 years, with severe dysmenorrhea, were treated with either naproxen, 48 women, or placebo, 49 women, for two consecutive menstrual cycles. No oral contraceptive was used. ⋯ Fewer patients had to stay in bed, or stay at home from work or school, in the naproxen group compared to the placebo group. Few side-effects were reported and most of them belonged to the dysmenorrhea symptomatology. No side-effects could be rement according to the patients' own judgement.

Randomized Controlled Trial Clinical TrialThe shape of the amniotic pressure curve before and after paracervical block during labour.
Paracervical block (PCB) given during labour reduces the uterine activity necessary for cervical dilatation. The aim of the present investigation was to find out whether this effect of PCB changes the form of the amniotic pressure curve. A preliminary investigation showed that the ascending limb of the amniotic pressure curve, A, consists of three phases. ⋯ The changes typical of PCB did not occur after epidural block. The discovery of the six phases of the amniotic pressure curve, their change after PCB and the results of other investigators make possible a suggestion of the basic physiological processes that influence amniotic pressure during coordinated labour contractions. It is held that the form of the amniotic pressure curve can be explained in terms of contraction, relaxation, and propagation of a contraction and a relaxation wave.
