[A single dose of antibiotic--as a prophylaxis during cesarean section].

The are shown the expediency of prophylactic antibiotics administration during cesarean section. The investigations contained 32 pregnant women who were given intravenously augmentin in dose of 1.2 g.

[The effect of meteorologic conditions on uterine contraction activity in patients with full-term pregnancy].

In 2892 cases with full-term pregnancy the influence of atmospheric conditions, such as pressure, temperature, speed of wind, humidity, circadian rise of pressure and temperature were analysed. During acute changes of temperature, pressure and humidity the beginning of delivery might be expected in 2 to 6 days.

[Pregnancy and labor in multiparae].

The course of pregnancy, labour and puerperium was analysed in 53 women in labour for the fifth time or more. It was found that many multiparae came from the lowest socioeconomic class and only rarely visited maternity clinics, as compared to the control group of 96 primigravidae and primiparae. They had more frequently earlier termination of pregnancy, premature rupture of membranes, and after labour incomplete placental expulsion and urinary tract infections were more frequent in them.

[Liver function disorders and blood coagulation disorders in the course of EPH gestosis].

Three cases of EPH-gestosis complicated with liver function and blood coagulation disorders (HELLP syndrome) are presented. The most frequent diagnostic errors and subsequent risk for both mother and fetus have also been discussed. Basing on the available literature, the safest management of pregnancy and delivery is critically assessed.

[Pregnancy and labor after artificial abortion].

The course of pregnancy, labour and puerperium was analysed in 170 women in labour after previous artificially interrupted pregnancy. They were compared with a group of 96 women in first labour. The women in labour after artificial abortion were older, had during pregnancy more frequently bleeding, gestosis, urinary tract infection.

[Neonatal blood aldosterone].

Postnatal aldosterone levels have been studied in 13 newborns from birth to the end of the 3rd day of life. The examinations were performed in children in whom blood samples were collected frequently for the clinical reasons (mostly because of suspected serologic incompatibility). Aldosterone level was measured by radioimmunoassay in the mixed cord blood and then at 2, 6, 12, 48, 72 hours after birth.

[Pregnancy and labor after spontaneous and induced abortion].

The course of pregnancy, delivery and puerperium has been analysed in 91 women after spontaneous abortion in the past, 170 women after artificial abortion and in 91 women during the first pregnancy. The women after abortion were characterized by the advanced age the more frequent hemorrhage during the pregnancy, the renal failures, the preterm deliveries and the gestoses. After the artificial abortions the deliveries were longer and the blood loss greater.

Congenital malformations and the environment.

The aim of the work was to search for the correlation between the environmental pollution and the ratio of congenital malformations found in the population of 54,493 newborn infants of three Silesian towns: Bielsko-Biała (situated in the mountains, close to a recreation part of the country), Bytom (situated in the center of an old industrial district, where industry is responsible for very high environmental pollution), and Tarnowskie Góry (situated close to vast woodlands, where very high environmental concentration of heavy metals is caused by an outdated, big zinc plant). In spite of big differences of environmental pollution indices between the three towns, the percentage of major congenital malformations diagnosed within the first three days of extrauterine life was almost identical (1.12% in Bielsko-Biała, 1.

Antenatal glucocorticoid administration and neonatal glycemia.

In the group of preterm newborns born after a single dose of Celestone chronodose given to the mothers (in order to avoid RDS syndrome) mean glycemia values at the 4th and the 12th hour after birth were not very different from the values observed in preterm newborns whose mothers were not treated with any glucocorticoid. Mean glycemia levels were significantly higher in those newborns who were fed early (within 4 h after birth) and intensively as compared with the babies traditionally not fed within the first 12 h after birth. The suggestions may be drawn out that: (1) A single dose of Celestone chronodose given to the mother 12 h prior to parturition does not influence the glycemia in the newborns.
