Purpose of investigation: The objective of this study was to evaluate the electrolytic status of Na+, K+, Ca2+, and Mg2+ in serum and red blood cells in idiopathic preterm and term deliveries. Methods: The study included 105 pregnant women diagnosed with idiopathic premature delivery (study group) and 36 pregnant women with physiologically term delivery (controls). Samples of mother's blood were collected and analyzed for the level of electrolytes in the serum/plasma and red blood cells. Results: Measured values of magnesium in red blood cells in the study group were far lower than physiological values, intracellular calcium levels were higher in the study group compared to levels measured in the controls. Sodium concentrations in cells were significantly lower in subjects with premature delivery. Conclusion: The magnesium intracellular level is the best representative value of magnesium in the body.

Objective: The aim of this study was to compare hemodynamic changes in the uterine and ovarian arteries between infertile women with moderate and/or severe endometriosis and healthy women. In this prospective study, 99 women in their generative age were subjected to color Doppler ultrasonography to measure hemodynamic parameters from July 2010 to January 2011. The examination was performed during the proliferative or ovulatory phase of the natural menstrual cycle in a random sample of 54 women treated for endometriosis-induced infertility and 45 healthy women were included in control examination procedure. Irrespective of considered stage, endometriosis was most often found in the ovaries, in the sacro-uterine ligaments, peritoneum, and rectovaginally. Resistance to blood flow expressed as the resistance index (RI) in the measured arteries, was significantly higher in severe endometriosis compared to moderate form. Average values of pulsation index (PI) and RI are significantly higher, in both endometriosis stages, compared to measured values in healthy women.

Objective: The objective of this study was an analysis of interobserver variability and positive predictive value (PPV) for BI-RADS categories requiring pathohistological evaluation: 4A, 4B, 4C, and 5. Material and Methods: Interobserver variability for each of descriptors as well as PPV for final BI-RADS categories requiring pathohistological evaluation was measured in a retrospective study which included 30 ultrasonographic reports, with pathohistological verification, randomly selected from ultrasonographic reports from Institute for Oncology and Radiology of Serbia where about 1,100 breast cancers are verified every year. Ten observers, seven gynecologists, and three radiologists, independently rated each ultrasonographic report according to the fourth edition of BI-RADS atlas. Interobserver variability was measured with k coefficient. Results: There was most conformity for a category of orientation (k = 0.79). Substantial degree of conformity was also present for both boundary (k = 0.71) and shape (k = 0.65) categories. Moderate degree of conformity was achieved for posterior features (k = 0.54) and margins (k =0.41) descriptors, while there was poor conformity in echogenicity (k = 0.38). In case of a final score, common conformity for all BI-RADS 4A, 4B, 4C, and 5 categories was (k = 0.51); it was the greatest for category 5 (k = 0.50), and it was less for categories 4C (k = 0.37), 4B (k = 0.32), and 4A (k = 0.29). Conclusions: Interobserver conformity for ultrasonographic descriptors and final evaluation of BI-RADS 4A, 4B, 4C, and 5 categories is good. PPV implies that not only division into categories 4 and 5, but also classification into categories 4 and subcategories 4A, 4B, and 4C are justified and clinically applicable.

Purpose of investigation: The aim of this study was to determine the rate of complications in pregnancy and during delivery, as well as neonatal outcomes, in women who underwent in vitro fertilization (iVF) and who are 40 years of age or older. Materials and Methods: This was a prospective study. The study group consisted of 29 women who underwent IVF. The control group consisted of 32 women who had a spontaneous pregnancy. Results: Pregnancy complications occurred in 86.21% of women in the study group, and in 46.87% of women in the control group. The proportion of cesarean sections (CS) was 84.62% in the study group, and 21.87% in the control group. Birth weight < 1,500 grams and < 2,500 grams was present in 17.16% and 22.86% of newborns in the study group, re-spectively. In the control group, birth weight < 1,500 grams and < 2,500 grams was present in 5.55% and 8.33% of newborns, respectively. Neonatal intensive care unit admissions included 22.86% newborns from the study group and 8.33% from the control group. Conclusion: Pregnancy, delivery, and neonatal complications were more frequent in the study (IVF) group.

The authors present the case of a 28-year-old nulliparous woman, who successfully carried a term pregnancy in a unicornuate uterus with a solid non-communicating rudimentary horn, and a history of myomectomy, without cerclage placement or tocolytic therapy. The patient was admitted to the present clinic for uterine fibroids and menorrhagia. The patient underwent laparotomy, during which a myomectomy was performed. Twelve months after the surgery, the patient conceived spontaneously. Routine obstetric ultrasounds revealed normal intrauterine fetal development. Cerclage and tocolytic therapy were not indicated at any stage of the pregnancy. A live female neonate was delivered via cesarean section at 39 weeks’ gestation. © 2019 S.O.G. CANADA Inc.

Purpose of investigation: To assess fertility and pregnancy outcomes in infertile patients after hysteroscopic myomectomy according characteristics of submucous fibroids. Materials and Methods: The authors included 56 infertile women, who were diagnosed with a submucous uterine fibroid, and assessed their fertility and pregnancy outcomes after hysteroscopic myomectomy, which was the exposure of interest. The control group consisted of 63 women who underwent a hysteroscopic polypectomy. The submucous fibroid and endometrial polyp were diagnosed preoperatively using 2D ultrasound, and the diagnosis was confirmed during hysteroscopy. All my-omectomies and polypectomies were performed using a resectoscope with a bipolar loop electrode. In the first postoperative year, the authors analyzed the rates of pregnancy, spontaneous abortion, preterm and term deliveries, as well as mode of delivery according to type, size, location, and number of submucous fibroids or polyps in each group. Results: In the first postoperative year, pregnancy occurred in 30.4% of patients. The greatest proportion of pregnancies occurred after removal of type 1 submucous fibroids, fibroids < 3 cm, and those localized on the posterior wall of the uterine corpus. Spontaneous abortion occurred in 7.1% of pregnancies, while delivery occurred in 19.6%. Term delivery occurred in 16.1%, while preterm delivery occurred in 3.6%. Vaginal delivery occurred in 14.3% of women, while caesarean section was performed in 5.4% of women. There were not significant differences in rates of pregnancy and delivery according to type, size, and localization of the fibroid or endometrial polyp. Conclusion: For infertile patients, in whom infertility is caused by a submucous fibroid, hysteroscopic myomectomy increases the pregnancy rate, and leads to good reproductive outcomes. © 2019 S.O.G.
