[Unilateral, sensorimotor femoral nerve paralysis following abdominal gynecological operation].

Unilateral or bilateral femoral nerve functional deficiency deficit occurs as a rare iatrogenic complication of gynaecological abdominal or vaginal surgery. Self-retaining abdominal retractors, that exert a constant pressure on the femoral nerve during the operation, are the most frequent cause. This situation occurs especially, if retractors of unsuitable size are used on very slender patients with thin abdominal walls. The favourable prognosis of the femoral nerve sensory and motor deficiencies can be complicated by damage to the knee joint resulting from leg muscle paresis. A personal observation and a literary review on sensomotor paresis after gynaecological abdominal surgery are discussed.

[The risk of conception during lactation].

The contraceptive effect of lactation is undisputed. Nursing increases the prolactin level in the serum. This hyperprolactinaemia suppresses all levels of the hypothalamus-hypophysis-ovary axis. The risk of ovulation can be greatly reduced by a proper nursing routine, frequency of nursing being credited with a greater anovulatory effect than duration of nursing. In addition, full nursing increases contraceptive safety. To prevent a drop in the serum prolactin level, nursing should also be done at night-time. Amenorrhoea during the lactation period is one of the most important prerequisites for an adequate contraception. The risk of ovulation increases dramatically, if vaginal bleeding occurs. However, the first cycles in the lactation period are often anovular and characterized by corpus luteum insufficiency. Lactation-induced amenorrhoea, nursing frequency of at least 6 x/day, nursing duration of at least 60 minutes/day, additional feedings of maximum 1 x/day and nocturnal nursing are the requirements for sufficient nursing-induced contraception. Even if these requirements are fulfilled, the risk of ovulation increases with the length of time post partum. Effective contraceptive protection is attained only up to the 9th p.p. week. If high post partum contraceptive safety is required, a mini-pill or micro-pill must be recommended. Lactation can only be recommended as a moderate contraceptive measure even in this case, an additional method (chemico-mechanical) should be initiated 3 months post partum.

[Investigations on the influence of Rh immunoglobulin prophylaxis on the immune response to postpartum rubella vaccination (author's transl)].

A preliminary investigation showed that patients with rubella HHT antibody titres of 1:8 or greater did not show a significant rise in the antibody titre following rubella vaccination. The rubella antibody titre was determined in 651 obstetric patients. Of these, 43 (6.6%) had no significant antibodies to rubella (HHT less than 1:8) and were included in the present investigation. Patients in Group A received 0.5 ml. of the rubella vaccine Meruvax on the fifth postpartum day. Patients of Group B(Rh negative and Rh positive) received 250 mug anti-D in a 16% gammaglobulin solution intra-muscularly 48 hours postpartum and the rubella vaccination 3 days later. Three weeks following the rubella vaccination the mean geometric rubella antibody titre had risen +/- 1 Standard deviation to 19.6 +/- 7.7 in Group A (17 patients) and to 18.0 +/- 6.3 in Group B (12 patients). Six weeks following the rubella vaccinations Group A (19 patients) showed titres of 61.7 +/- 2.9 and Group B (14 patients) showed titres of 70.0 +/- 2.6. There was no statistically significant difference (greater than 0.5). The conversion rate in both groups was 100%. Patients can therefore be vaccinated against rubella in the postpartum period even though they will receive a concomitant prophylaxis with Rh immunoglobulin.

[Alpha-fetoprotein: its significance in the monitoring of "at risk" pregnancies (author's transl)].

Having plotted a curve showing the normal values of Alpha-Foeto-protein (AFP) concentration in maternal serum and amniotic fluid, its significance in the monitoring of "at risk" pregnancies was examined and critically judged in the light of statements found in the literature. According to the results gained AFP determination in maternal serum or amniotic fluid can only be used with reservation as a monitoring test in "at risk" pregnancies. In particular in Rhesus Incompatibility it was impossible to establish the degree of foetal Haemolysis or to determine the best time for premature induction. In addition an intra-uterine death could not be predicted with certainty.
