An increased incidence of EPH gestosis in twin pregnancies is frequently reported. During the past 12 years, 188 women gave birth to twins in our hospital. For these mothers, the incidence of EPH gestosis on admission was 42.5%, in contrast to 31.4% for a control group matched for age, parity and nationality. EPH gestosis occurring in twin pregnancies was more severe than that in single pregnancies.
In the study reported here, 554 cases of postmenopausal bleeding were analyzed, i.e. 4.1% of the gynecological cases admitted during the 11 years from 1961 to 1971. In over one-third of these cases (35.3%) bleeding was caused by genital carcinoma. Among nonmalignant causes, endometrial atrophy was the most common (28.5%) followed by uterine polyposis (21.2%). As expected, corpus carcinoma (51%) was the most commonly found malignant genital disease, followed by cervical cancer (38%) which, surprisingly, is almost as common. The time-lapse between onset of bleeding and hospitalization with diagnosis is alarmingly long. In our patients it averages 19.2 weeks, is 36.3 weeks in corpus carcinoma cases and 16.3 weeks in women with cervical cancer.
To perform episiotomy, 89 women after childbirth were anaesthetized with either halothane (50 patients), methoxyflurane (24 patients) or chloroform (15 patients). The activity of the uterus was registered tocodynamographically. To examine the alternate influence of narcotics and uterotonica, 57 patients were pre-medicated with sintocinon and methergin i.m. as a prophylaxis. The second group (32 patients) received no premedication to stimulate labor activity, however in 18 cases towards the end of narcosis oxytocin and methergin were given i.v. In addition to these examinations 5 vaginal deliveries were anaesthetised with halothane only. Concerning our own experimental study it can be observed: 1. The relaxative properties of halothane wich suppresses completly the activity of myometrium during the deep stages of anaesthesia are superior to chloroform and methoxyflurane. 2. More rapid relaxation of the uterus with halothane compared with chloroform and methoxyflurane. 3. After the use of halothane a quicker return of the activity of the uterus compared with chloroform and methoxyflurane. 4. The value of a prophylaxis with uterotonica can be demonstrated by a comparatively reduced slowing-down of labour-activity during anaesthesia. 5. In every one of the cases, an interuption of the labour-suppressing, caused by the anaesthesia, can be obtained by injecting intravenously oxytocin or methergin. 6. During vaginal delivery, compared to the post placentar phase, there is no need for higher concentrations of halothane to be used to suppress labour contractions. The discussion deals with the intensity of reduction of the uterus contraction caused by the above mentioned narcotics, the dangers of the atony of the uterus, and the indications and contra-indications of obstetrical anaesthesia with halothane or methoxyflurane.

In 257 patients with primary or secondary infertility, tubal occlusion or impeded tubal patency was found. The patients received Bactrim or Tandearil and the tubal patency was retested. In a control group of 74 cases, 2 tubal patency tests were done without treatment. Following treatment with Bactrim, 40,4% of the previously occluded fallopian tubes were patent. Following treatment with Tandearil, 34% of the previously occluded tubes were patient. In the non-treated group, 25% of the cases showed tubal patency at the second patency test. The results were more striking for the cases with impeded tubal patency. The success rate was 73,3% following treatment with Bactrim, 50% following treatment with Tandearil and 26,7% in the untreated control group.
