Thrombospondin binds normally to glycoprotein IIIb deficient platelets.

Glycoprotein IIIb (GPIV, CD36) has been proposed as the platelet receptor for thrombospondin (TSP). We found two healthy blood donors, whose platelets were shown to be GPIIIb deficient. These platelets expressed endogeneous TSP as control platelets and their binding capacity for exogeneous TSP was the same. These results indicate that GPIIIb is not the major TSP receptor on platelets. However, it is not yet possible to exclude that in GPIIIb-deficient platelets other proteins may substitute for GPIIIb in TSP binding.

[Maternal morbidity following cesarean section: effect of infection control and preventive use of antibiotics].

1. Between 1976 and 1986, data were collected prospectively by a nurse specializing in hygiene on postoperative infections in the 3508 low cervical cesarean sections carried out at the University Gynecological Clinic in Tübingen. Over the past four years, this has also included data on noninfectious complications. During this 11-year period, the rate of sections rose from 10.3% to 18.2%. 2. During the first seven years, in which only hygienic, organizational, and surgical measures were used to prevent infection, the rate of patients with postoperative infections decreased from 28.2% to 11.9% (-58%), while the rate of feverish standard morbidity decreased from 27.2% to 9.7% (-64%). 3. Over the past four years, in which 60% of the patients received a perioperative antibiotics prophylaxis consisting of three doses of a cephalosporin, the number of patients with infections has decreased further to 8.6% (-28%), and the number of those with feverish morbidity to 3.7% (-62%). Over the total period, the reduction in the named parameters was 70% and 86%. 4. The most frequent infections were urinary tract infections (mainly cases of asymptomatic bacteriuria), infections of the abdominal wound, and endomyometritis and phlebitis of the arm owing to intravenous applications. Only the reductions in the number of cases of bacteriuria (-77%), wound infections (-72%), and endomyometritis (-73%) reached statistic significance. 5. As a result of antibiotics prophylaxis, the rate of infections in the case of primary section decreased from 15.3% to 9.0%, and in the case of secondary section from 15.1% to 8.2%; feverish standard morbidity decreased from 9.1% to 3.5% and from 9.4% to 4.9%.(ABSTRACT TRUNCATED AT 250 WORDS)

[Maternal morbidity following cesarean section. Comparison of isthmo-corpus longitudinal section and isthmian transverse section in premature labor].

In an increasing number of cases of the Caesarean delivery of small premature babies (length of gestation less than 32 weeks or an estimated weight of less than 1501 g) between April 1983 and March 1987, the uterus was opened by an isthmo-corporeal longitudinal section if the lower uterine segment appeared too narrow for a gentle delivery via an isthmian transverse incision. A comparison of 67 Caesarean deliveries of this type with 116 Caesarean deliveries of the same small premature babies using an isthmian transverse incision did not reveal any difference with regard to postoperative infections, feverish standard morbidity, or other noninfectious complications. In comparison with Caesarean deliveries of older babies, the Caesarean deliveries of small premature babies had significantly more infectious and noninfectious complications, such as cases of phlebitis of the arm owing to intravenous application (2.7% as against 1.0%), posthemorrhaging and hematomas (3.8% as against 0.8%), and blood transfusions (3.3% as against 0.8%). The number of infectious complications was significantly reduced by a perioperative antibiotics prophylaxis. The question of late complications as a result of the isthmo-corporeal longitudinal section, especially the danger of rupture of the uterine scar in the event of a subsequent vaginal delivery, has not yet been resolved.

[Decrease in nosocomial infection based on continuous monitoring and control. 7 years' experience in a women's clinic].

During a seven-year programme of surveillance and control of infection data were collected by a specialist hygiene nurse on 47 551 gynaecological, obstetric and post-partum patients. The infection rate was highest (40.5%) after major surgical procedures. Infection rate after cesarian section was 16%, eight times the rate after vaginal delivery (2%). The most frequent type of infection was of the urinary tract (70%), usually asymptomatic bacteriuria. Next most frequent were pelvic infections, abdominal wound infections, and phlebitis via an intravenous entry in long-term parenteral nutrition. During the period of observation bacteriuria rate decreased by 75%, the other nosocomial infections by 64%, febrile standard morbidity by 81%. The decrease is largely due to the infection surveillance programme with the employment of a specialist hygiene nurse.

Cross Infection

[Nosocomial infections (author's transl)].

Within 3 years 2546 nosocomial infections were registered among 18 897 hospitalised patients of a gynaecological-obstetric university hospital, Results were obtained in a prospective study on the use of nurses specially trained in hygiene. The incidence of nosocomial infections was 13.5% including predominantly asymptomatic bacteriurias and 3.9% without bacteriurias. It was higher after major surgical intervention and lowest in pregnant women, postnatal patients, vaginal deliveries and minor operations. Bacteriurias were the most common infection in all patient groups. They made up 71% of the total, followed by postoperative pelvic infections (7.3%), phlebitis at the site of infusion (6.5%) and abdominal wound infection (4.2%). During the control programme, introduction and reinforcement of various hygienic measures and continuous instruction and control of the wards and treatment rooms by the specially trained nurses the incidence of all nosocomial infections decreased by 48.1% and of urinary tract infections by 42.7%.
