RESUMO
The diagnostic utility of serum and urinary human chorionic gonadotropin (hCG) measurements and serum measurements of pregnancy-specific beta 1-glycoprotein (PSBG), placental lactogen, and cystine aminopeptidase (CAP) was prospectively studied in 51 consecutive patients with suspected ectopic pregnancy who underwent laparoscopy or laparotomy. CAP was not detected in the sera of any patient with ectopic pregnancy. False-positive results in each assay were found in patients with intrauterine pregnancy or missed abortion. The overall efficiency of the tests were: urine hCG slide test, 47%; urine hCG tube test, 80%; serum hCG, 86%; serum PSBG, 82%; and human placental lactogen, 60%. Although measurement of serum hCG by radioimmunoassay is the most accurate biochemical test in predicting the correct diagnosis in patients with suspected ectopic pregnancy, the relatively high efficiency of the urinary hCG tube test, coupled with its ease of performance, low cost, and rapid turnaround time, makes it the most practical screening test.

The objective of management in the pregnant diabetic patient is to achieve physiologic glucose homeostasis through the use of diet and insulin. As outlined, the numerous ancillary tests developed during the past 15 years to assist the clinician in determining impending fetal death have left much to be desired, especially where metabolic homeostasis has not been achieved prior to the thirty-sixth week of gestation. The statistics from this institution indicate that the maintenance of the plasma glucose concentration below 100 mg. per cent throughout gestation, regardless of the severity of the diabetes, all but removes the risk of maternal-fetal complications due to diabetes. The management is uniform for all patients exhibiting an abnormality of carbohydrate metabolism, and, although it is rather difficult to accept, there have been minimal neonatal complications when the protocol outlined in this presentation has been followed.
