[The effect of antenatal corticosteroid prophylaxis in premature newborns with the use of surfactant therapy].

The study is retrospective aiming to elucidate the effect of antenatal corticosteroids (CS) for prevention of RDS in preterm deliveries, followed by surfactant therapy. 28 premature babies from 26 to 31 gest. weeks, receiving Curosurf at birth, were included in the study.

[The dynamics and trends in surgical delivery at the Maternity Home of the State Institutional Hospital].

The study discusses the frequency of operative obstetric deliveries (cesarean section, forceps extraction and vacuum extraction) over a period of 18 years from 1976 till 1993. A total of 100,545 deliveries with 100,192 livebirths took place during this period with a decrease of the annual number of deliveries in the last years. The frequency of the various kinds of operative deliveries shows different tendencies.

[The static and dynamic profiles of urethral pressure in women with stress incontinence and in healthy controls].

The study presents the results of urethral pressure profile measurements in 3 groups of women: continent nulliparous, continent parous and stress incontinent women. The maximum urethral closure pressure, the functional urethral length and the length of continence zone are compared. The healthy control groups (both parous and nulliparous) show much higher maximum urethral closure pressures than those mentioned in literature.

[The role of serum beta-HCG levels for the diagnosis of ectopic pregnancy].

The study includes 56 cases of women admitted at Second gynaecology clinic of the University Maternity Hospital Sofia with evidence or suspicion of having an ectopic pregnancy who had their serum beta-HCG levels determined quantitatively. 27 of them showed no beta-HCG in their sera and none turned out to have pregnancy, neither intrauterine nor ectopic. All cases of ectopic pregnancies (a total of 20) were associated with detectable beta-HCG levels in the serum.

[The treatment of urinary stress incontinence with the sling and Pereyra's suspension].

Patients with proven stress incontinence were subjected to surgical treatment which combined both sling and Stamey-Pereyra techniques. A 3-4 cm long and 1,5-2 cm wide sling of Bulgarian polyamide mesh was placed under the urethrovesical junction using a small vaginal incision. Two long polyamide sutures were tied to either end of the mesh and were retrieved from the vagina to the abdomen by Pereyra needle inserted through two small suprapubic incisions and guided by the vaginal forefinger.

[Cardiotocographic control during labor].

The authors discuss different aspects of intrapartum foetal monitoring. The scientific basis of foetal intrapartum foetal monitoring are pointed out. The authors present three groups of cardiotocographic signs which should alarm the obstetricians: warning signs, threatening signs and clear signs for foetal distress.

[The early breast feeding of newborn infants].

Breast feeding was started at the age of 2 hours after birth, immediately after mother and baby were transported to the clinic for healthy term newborns. Our aim was to investigate the influence of the early start of breast feeding on the development of the newborns and on their mothers, as well as to compare the results with those, obtained when breast feeding had begun on the 6-th hour after birth. The results from our work show that the earlier the beginning of breast feeding, the earlier and the more effective the consolidation of the process.

[The importance of x-ray pelvimetry for the prognosis of pelvic dystocia].

The frequency of roentgenological pelvimetry at the Research Institute of Obstetric and Gynecology during 1988 is 4.79%. Thirty-five pelvimetries out of 276 (12.

[Doppler study of the fetal and uteroplacental blood flows in IUGR].

It was established during Doppler examination of the fetal and uteroplacental blood flow in intrauterine retardation in the growth of the fetus (IUGR) that the mean velocity of blood flow in the fetal aorta was 29.21 +/- 3.98 sm/s.

[Doppler study of the fetal and uteroplacental blood flows in normal pregnancy].

The Doppler examination of the fetal and uteroplacental blood flow established that the mean velocity of the blood flow in the fetal aorta was 32.46 +/- 2.13 cm/s, in the arcuate artery--60.

[The effect of partusisten on the rate of blood flow in the fetal aorta].

It is established that the mean velocity of blood flow (Vmean) of the fetal aorta in pregnant women with pre-term deliveries during Doppler examination is 40.70-3.26 cm/s, but in women with normal pregnancy (a control group) is 32.

[X-ray diagnosis of submucosal fibromyoma].

Data on hysterographic examination are analysed in 57 women, in whom there are roentgenologic signs for myomatous nodes, localized submucosally. An attempt is made to systematize characteristic changes in this lesion (measures, location, form and outlines). A conclusion is reached that roentgenological examination with the possibility objectively to establish the existence of submucous myomas, on the one hand and to determine their typical morphological peculiarities, on the other, could help to diagnose cases with obscure clinical history.

[Comparative evaluation of methods for the diagnosis of submucosal myomatous nodules].

The authors examined 33 women at fertile age with complaints of dysfunctional uterine bleedings, not affected by medicamentous therapy and absence of convincing data for changes in the gynecological status. Probatory curettage was made in 18 out of 33 women, but ultrasonic examination was made on the other 15 patients. We compared the obtained results with the data from hysterographic examination.

[The place of x-ray pelvimetry in obstetrical practice].

The frequency of roentgenological pelvimetry, its changes in accordance with obstetric management of labour and its place in the obstetric practice were studied at the Research institute of Obstetric and Gynecology for the period of 1979-1988. It was established that its mean frequency for the investigated period was 7.0%, but its highest frequency--11.
