New immunochemical method for rapid detection of human choriogonadotropin in urine.

We describe a visual assay for rapid detection of choriogonadotropin (hGC) in human urine, and evaluate a pregnancy test kit that is based on this assay and designed for use by the general public. The assay involves the formation of an antibody-antigen complex between the anti-hGC antibodies coated on the membrane protein of Staphylococcus aureus bacteria, prestained with hematoxylin, and the hGC concentrated on a column of Sepharose-concanavalin A. The test was calibrated to detect as little hGC as 0.9 (SD 0.15) int. unit/mL. The kit, clinically tested with 448 urine samples, was 99.6% accurate. Simple to perform, the test gives highly reliable results as early as five days after the missed menstrual period.

Characterization of the growth-discordant twin.

A computer-assisted analysis of perinatal variables was undertaken in order to characterize the growth-discordant twin. We studied 124 twin pairs grouped at four degrees of discordancy: over 5, 10, 15, and 20% birth weight difference, using the larger twin as 100%. Twins with birth weight discrepancy below these figures were considered concordant. Highly discordant second twins showed significantly lower birth weight, gestational age, and Apgar scores, and prolonged neonatal hospitalization, as compared with discordant first twins. Complex presentations and a higher cesarean section rate characterize discordant first and concordant twins. It is suggested that a 15% birth weight discordancy be used as the safety limit for birth weight disparity. We also recommend special attention when discordancy seems to increase, especially if the discordant is the second twin.

Idiopathic hypoparathyroidism with gestational diabetes.

A case of gestational diabetes complicating the pregnancy of a hypoparathyroid gravid patient is presented. Labor was induced by prostaglandin E2 vaginal tablets, but delivery was by cesarean section. Separate treatment of the two endocrinopathies was successful. After the induction of labor, hypocalcemia and hypoglycemia were seen, and they may have been caused by the prostaglandin E2.

Clinical aspects of ovarian tumors of low malignant potential.

A review of 21 cases of ovarian tumors of low-malignant potential diagnosed in our department over a period of 13 years was undertaken. Ninety percent of the patients presented with stage I disease. The average age at diagnosis (45 years) was younger than commonly found in patients with invasive epithelial cancer. Three patients received postoperative chemotherapy, and all of those were evaluated by second-look laparotomy. One of our patients with stage Ic serous tumor recurred with lung metastases. In two other patients with mucinous tumors, mucocele of the appendix was found. The five year survival in this series was 100%. Our study emphasizes the need for a prospective study to evaluate the value of adjuvant therapy in the various stages of these ovarian neoplasms.
