Assessment of fetal lung maturity by a microviscosimeter.

A new method of rapid antenatal assessment of fetal lung maturity was evaluated in relation to the newborn outcome and two other accepted test. This method is based on fluorescence depolarization (FD) technique. The special instrumentation required for this method (the Microviscosimeter) was found to be simple and easy to handle even to nonprofessional personnel. Analysis of 47 samples of amniotic fluid received within 48 hours of delivery demonstrated that lung maturity threshold may be related to a numeric value (P value) measured by this technique. With a P value of less than 0.320 respiratory distress syndrome (RDS) is unlikely to develop. With a P value greater than 0.340, chances for RDS, usually severe, are high. With a P value of less than 0.340 but greater than 0.320, RDS may or may not develop. This method did not prove to be more reliable then the determination of L/S ratio by thin layer chromatography, but its advantage is that it supplies the results in less then an hour. The FD technique proved to be more reliable then the commonly used foam stability test.

Estrogen-androgen levels in aging men and women: therapeutic considerations.

The influence of aging on serum levels of gonadotropins (FSH and LH), testosterone and estradiol was studied in the following groups: 4 normal men (ages 30 to 50), 38 men with symptoms of the male climacteric (ages 51 to 84), 25 men with relative impotence (ages 31 to 50), 10 normal women (ages 24 to 31), and 6 menopausal women (ages 58 to 76). FSH and LH levels began to rise in men in their 40's, and the increase became more conspicuous in the later age decades. The degree of elevation was nowhere comparable to that observed in the aging women. In the male, the serum testosterone levels showed a progressive decrease from the fifth age decade onward, whereas in the female there was an increase after the menopause. Estradiol levels showed no significant change in the aged male, but they were somewhat higher than in the aged female. Exceptions to the low-testosterone and low-gonadotropin relationship were observed in individual cases and might be explained by relatively high estradiol values. Proper replacement therapy by means of estrogens for the postmenopausal female and androgens for the aging male is often of great benefit, physically and emotionally.

FSH and LH response to LHRF in Kallman's syndrome.

The olfacto-genital syndrome (Kallman's syndrome) is believed to be primarily an hypothalamic disorder resulting in hypogonadotropic hypogonadism or hypo-ovarianism and anosmia. The pituitary response in 2 patients was measured on dialy subcutaneous injections of 100 mug of LHRF. One of the patients was also studied in a similar fashion by administration of LHRF intravenously for 4 consecutive days. A greater response occurred with the subcutaneous route.

Effect of LHRH stimulation in anovulatory women.

Serum FSH and LH and levels were determined at different time intervals after the subcutaneous administration of 100 mug LHRH to 24 females. Serum FSH levels were of the same order in the oligomenorrhea-amenorrhea and the Stein-Leventhal group of patients but elevated in gonadal failure. There was a great degree of overlap between serum LH values in the three groups. Gondal failure patients, however, could be distinguished from the other two groups because these patients had an elevation of both serum FSH and LH, and the response to LHRH was considereably exaggerated in comparison to the other two groups.

Use of propranolol in dysfunctional labour.

Labour pains associated with fear and anxiety increase the blood level of catecholamines. This in turn causes dysfunctional labour due to the weak uterine contractions which follow stimulation of uterine adrenergic beta receptors. Intravenous propranolol was administered to ten primigravidae with typical dysfunctional labour. This was shortly followed by normal uterine activity and delivery without any significant maternal or fetal complications. To the best of our knowledge this is the first attempt to treat dysfunctional labour by the intravenous administration of a beta-blocking agent, and our preliminary results are encouraging.
