Replacement estrogen therapy for menopausal vasomotor flushes. Comparison of quinestrol and conjugated estrogens.

Quinestrol, conjugated estrogens, or placebo was used to treat 156 patients with pernicious vasomotor instability in a prospective, double-blind, randomized, multiinvestigator trial. Vasomotor flushes were severe in approximately 80% of the cases and moderate in 20%, relatively equally distributed among the various drug groups. Both qinestrol and conjugated estrogens were significantly more effective than placebo in relieving vasomotor symptoms (by chi2 analysis, P less than or equal to 0.

Calcium, magnesium, phosphorus, and parathyroid hormone interrelationships in pregnancy and newborn infants.

The ability to measure directly human parathyroid hormone (hPTH) and ionized calcium (Ca++) is of fundamental importance in understanding their interrelation in pregnancy and the newborn. hPTH and Ca++ progressively increase throughout pregnancy. Since Ca++ is the direct determinant of hPTH levels, a different "set point" appears to be operative throughout pregnancy.

Unexplained infertility. A reappraisal.

During a 30-month period 229 couples were evaluated for infertility at the Naval Regional Medical Center, Oakland. Laparoscopy was used in all cases of otherwise unexplained infertility. The resulting laparoscopic examination of the female partner of 24 such couples demonstrated abnormal findings in 18 (75%).

Gonadotropin secretion and hypothyroidism.

Hypothyroidism is generally associated with hypogonadotropism. Occasionally, however, increased gonadotropin concentrations are encountered. The mechanisms, presumably hypothalamic, which determine the gonadotropin shift are unclear.

Effect of intramuscular triamcinolone acetonide on the human ovulatory cycle.

The effect of intramuscular triamcinolone acetonide (TCA-A) on pituitary gonadotropins and ovarian hormones was studied in a normally menstruating woman. Serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well estradiol 17-beta (E2) and progesterone (P), were determined daily in a normal "ovulatory" pretreatment cycle. A total of 160 mg of TCA-A was then administered in four injections over two and a half months.

Improved glucose control in nonhospitalized pregnant diabetic patients.

Methods for management of diabetic pregnancy in the outpatient setting require strict glucose control. To assess the effect of diet and injection of short and intermediate acting insulin on glucose, diabetic patients tested their urine daily for glucose and had biweekly serum glucose tests. A brief metabolic ward study in 9 diabetic patients during the third trimester yielded hourly glucose determinations.

Circadian variation of serum glucose, C-peptide immunoreactivity and free insulin normal and insulin-treated diabetic pregnant subjects.

To examine differences among pregnant diabetic and nondiabetic subjects, serum glucose, and immunoreactivity of C-peptide, free and total insulin were measured at hourly intervals during a 24--h third trimester metabolic ward evaluation. Six normals, three mild, and four juvenile-onset type diabetics were studied. Diets were identical for all subjects.

Long-term intramuscular administration of triamcinolone acetonide. Effect on the hypothalamic-pituitary-adrenal axis.

Five patients received intramuscular injections of triamcinolone acetonide for periods ranging from five months to three years. Metyrapone tartrate testing was used to assess the function of the hypothalamic-pituitary-adrenal (HPA) axis during, after, and, in one case, before the drug therapy. The HPA axis function was found to be suppressed during the period of treatment and up to ten months after cessation of therapy.
