[Urine cytology as a supplement to cystoscopy and biopsy in the control of bladder tumors].

Throughout the years several investigations have either recommended or discredited exfoliative urine cytology because of high incidence of false negative or false positive results. Most authors agree that high grade bladder tumors are diagnosed with fairly high certainty (80-87%) by using exfoliative urine cytology whereas the value of urine cytology of low grade bladder tumors is uncertain. This investigation, including 200 patients who came for cystoscopic control of bladder tumors, revealed 87% accordance between cystoscopic biopsy and exfoliative urine cytology of high grade tumors while there were 47% false negative and no false positive of low grade tumors. On this background, it must be concluded that exfoliative urine cytology is an important investigation in diagnosing and controlling patients with bladder tumors, but the method can not always stand alone.

Tumour of female paraurethral duct. Immunohistochemical similarity with prostatic carcinoma.

A case of adenocarcinoma derived from a female paraurethral duct is described. Morphologically the tumour looked like a prostatic adenocarcinoma. Furthermore, the tumour cells stained positively with antibodies to prostatic specific antigen and prostatic specific acid phosphatase. The karyotype of the patient was 45,x/46,xx/47,xxx/46,xt(x;13)(p11;q22) demonstrating that the patient was not a hermaphrodite. The tumour therefore represented female homology of a prostatic adenocarcinoma.

Hyperprolactinemic amenorrhea induced by metoclopamide (PrimperanR).

Secondary amenorrhea, elicited by metoclopamide (PrimperanR) induced hyperprolactinemia, was found in a 24-year-old woman. Withdrawal of the drug was followed by normalization of the hyperprolactinemia, as well as the menses. For many years metoclopamide (PrimperanR) has been used for various dyspeptic inconveniences, such as gastro-esophageal reflux, ventricular rentention and postoperative tarm-atom. Well-known secondary effects are reported to be drowsiness, uneasiness, restlessness and extra-pyramidal secondary effects in the form of acute dystom. The present case of secondary amenorrhea caused by metoclopamide (PrimperanR) induced hyperprolactinemia has been verified clinically, serologically and by treatment.

Hemoglobin A1c determinations in diabetic pregnancy.

To investigate the relationship of hemoglobin A1c (HbA1c) to average blood glucose concentration and to birth weight of infants of diabetic mothers, HbA1c was determined in 42 consecutive insulin-dependent pregnant diabetic women in the third trimester. HbA1c correlated significantly to the average blood glucose levels in the preceding 8 wk (r = 0.73, P less than 0.001). No correlation was found between HbA1c and the relative birth weight ratio (RBWR) for all newborn infants. However, in the major subgroups of pregnancies, White class B and C without prognostically bad signs in pregnancy (PBSP), HbA1c in the third trimester significantly correlated to RBWR (r = 0.59, P less than 0.01). In a subgroup of six pregnant diabetic women in whom HbA1c and blood glucose concentrations frequently were determined from the 13th to the 33rd gestational week, a relationship between HbA1c and the average blood glucose concentration of the preceding 8 and 12 wk in the individual pregnant subject was established. In spite of this correlation, HbA1c was found to be a poor predictor of the average blood glucose concentration in the individual patient. This indicates that HbA1c cannot satisfactorily describe the degree of diabetes control without simultaneous determinations of blood glucose. HbA1c determinations were found to be of value as an additional indicator of the quality of regulation during ambulatory control in diabetic pregnancy because an increase in HbA1c suggested an impairment of diabetic control. The perinatal mortality and morbidity of the infants of diabetic mothers were satisfactory in this series, as only one perinatal death, one nonserious malformation, and two cases of mild respiratory distress syndrome occurred among the 43 infants.
