[History of gynecology and perinatology in Croatia. Midwifery. Clinics and hospitals in Zagreb].

The development of obstetrics in Croatia and the formation of unique discipline of obstetrics and gynecology in Croatia in first ten years of 20th century are presented. The midwifery is mentioned in Croatia for the first time in Dubrovnik in 14th century. The "protomedicus" from Varazdin Johan Baptist Lalangue in 1777 has published the booklet "Brevis institutio de re obstetritia". First public school of midwifery was founded in Zadar on 1820 and the second one in Zagreb in 1877. In Zadar, Ante Kuzmanić, "magister obstetritiae et chirurgiae" published a short textbook "Sixty lessons from midwifery for midwifes", thereafter in 1908 Nikola Lalich "Book for midwifes". In Zagreb, Antun Lobmayer published in 1877 "The midwifery". Gynecology was developing in the second half of 19th century as a part of surgery. On break-time from 19th to 20th century rose the unique medical profession obstetrics and gynecology. In Croatia the unique discipline established Dr Franjo Durst, since he was in 1905 installed for the first head of Royal Country Maternity Hospital in Ilica street and thereafter in 1921 for the first head and university professor of Royal University Clinic for Gynecology and Obstetrics in Petrova street. The evolution of gynecology and obstetrics, respective of perinatology, during last 30 years, in the Zagreb in departments of clinical hospitals "Clinical Hospital Center", "Sestre Milosrdnice", "Merkur" and "Sv. Duh" is presented.

The effect of fetal hypoxia and acidosis on the changes in fetal electroencephalogram during labor.

As artefact-free recordings of the fetal brain bioelectric potentials can only be obtained by specially designed electrodes, an electrode for taking electroencephalogram (EEG) and cardiotocogram (CTG), according to the principle of vacuum electrode developed by Rosen and Scibetta, has been designed. The polygraphic technique was used to examine a total of 65 deliveries, divided into two groups. The first group (n = 33) consisted of newborns free of any signs of hypoxia and acidosis, whereas the second group (n = 32) was comprised of newborns with evident clinical and biochemical signs of hypoxia and acidosis. Fetal hypoxia and acidosis were observed to entail some characteristic changes in EEG, that is, a decrease in the frequency and wave amplitude through the appearance of the isoelectric line (ISO) featuring in severe cases of fetal hypoxia and acidosis. The following changes were found to occur during the development of hypoxia and acidosis:hypoxia, a decrease in the EEG frequency and amplitude, preacidosis with the appearance of both early and late decelerations coupled with a significant drop in the oscillation and, eventually, severe variable decelerations accompanied by terminal bradycardia. The time interval between the manifestation of initial signs of a decreasing central nervous system (CNS) activity and changes in the fetal heart rate was found to be about 10 minutes.

HLA antigen studies in women with recurrent gestational disorders.

The frequencies of HLA antigens were determined in an experimental group of women with recurrent gestational disorders mainly expressed as spontaneous abortions of unknown etiology. The estimated antigen frequencies in this group were compared with the antigen frequencies in 158 unrelated persons (79 couples with no record of secondary infertility). A significantly higher frequency of antigen HLA-A9 was found in the experimental group as compared with the controls (corrected P = 0.0015). A greater degree of HLA compatibility was found between each woman from this group and her husband, considering 45 couples, as compared with 79 control couples. These results indicate that gene(s) close to the HLA region may have an influence on the reproductive performance in humans.

The HLA antigens in women with recurrent abnormal pregnancies of unknown etiology.

Women with recurrent abnormal pregnancies of unknown etiology--as compared with those with recurrent abnormal pregnancies of known etiology and with normal controls--had a significantly increased frequency of antigen HLA--A9 (corr. P less than 0.01). Analysis of the frequencies in matings performed at different levels of HLA incompatibility between parents in 35 couples with recurrent abnormal pregnancies of unknown etiology revealed a high degree of wife husband compatibility of the antigens of the HLA--A locus, but not of the antigens of the HLA--B locus. These results indicate that the HLA chromosomal region may influence the reproductive efficiency and the fate of the fetus.
