Thiamine deficiency-induced gestational polyneuropathy and encephalopathy. A case report.

A 22-year-old multigravida presented with polyneuropathy and encephalopathy at 18 weeks' pregnancy. After excluding other applicable conditions, the diagnosis of a hyperemesis-induced thiamine deficiency was made. With the necessary vitamin supplementation the patient gradually recovered over a period of 4 months and was delivered of a normal infant at term. Gestational polyneuropathy and encephalopathy due to thiamine deficiency has very rarely been reported. The literature is reviewed with discussion of the differential diagnosis, the treatment and the prognosis.

Youssef's syndrome: a case report.

Youssef's syndrome, or menouria following a vesicouterine fistula, has been reported rarely. This case differs from the previously reported cases in that the menouria was caused by a double vesicocervical fistula and that, in contrast to the generally preferred transabdominal approach, a transvaginal approach was used for successful surgical repair of the fistulas.

Complications in 8509 laparoscopic Falope ring sterilizations performed under local anaesthesia.

During the 3-year period 1 January 1980-31 December 1982, 8509 laparoscopic Falope ring sterilizations were performed under local anaesthesia in rural areas of the Cape Province by the Sterilization Service of Tygerberg Hospital. Despite the fact that 476 of the patients had undergone previous lower abdominal surgery, major complications (anaphylactic shock after injection of lignocaine and inadvertent perforation of the bladder by the trocar) occurred in only 2 cases. It was not possible to complete the sterilization under local anaesthesia in 98 cases, resulting in a technical failure rate of 1.15%. A prospective study of the minor complications encountered among the 193 patients sterilized during November 1982 showed that torn tubes occurred in 3.1% and uterine perforation in 2.1%. This can be partially explained by the fact that evidence of previous pelvic infection was seen during laparoscopy in 9.3% of cases. The pregnancy rate after sterilization was 0.28% for the group as a whole.

[Interval Falope ring sterilization in the Cape Province: experience with 9175 cases over 4 years].

During a 4-year period 9175 women were sterilized under local anaesthesia by the laparoscopic Falope ring method. These procedures were performed in smaller towns in the Cape Province. The method used, its cost-effectiveness, and its acceptability to patients are described in detail. This venture proves convincingly that a highly sophisticated medical service can be made available to rural areas, ensuring greater support for a high-priority primary health care service.

[Assessing the incidence of asymptomatic bacteriuria in pregnancy by means of the Dornfest method as a screening test].

In a study to assess the incidence of asymptomatic bacteriuria in pregnancy, as determined by the Dornfest method of urine examination, results proved to be positive in 7% of patients. Of these patients 28% developed acute pyelonephritis during pregnancy. The Dornfest method can be used successfully as a screening test for asymptomatic bacteriuria at antenatal visits and the necessary treatment can be instituted, lowering the incidence of acute pyelonephritis, a condition which remains the most frequent cause for admission to hospital of a pregnant patient.

[Bladder neck incompetence in the female].

Bladder neck incompetence is responsible for 15,5% of true anatomical defects that cause stress incontinence in the female. Confirmation of the diagnosis of this condition, as well as a new surgical technique for the repair of the defect, is described.
