RESUMEN
INTRODUCTION: Cephalopelvic disproportion (CPD) is one of the most common obstetric complications. Since CPD is the disproportion between the fetal head and maternal bony pelvis, evaluation of the head circumference (HC) relative to the maternal bony pelvis may be a useful adjunct to pre-labor CPD evaluation. The aim of the present study was a proof-of-concept evaluation of the ratio between HC and pelvic circumference (PC) as a predictor of CPD. METHODS: Of 11,822 deliveries, 104 cases that underwent an abdominopelvic CT for any medical indication and who underwent normal vaginal deliveries (NVDs) (n = 84) or cesarean deliveries (CD) due to CPD (n = 20) were included retrospectively. Maternal pelvis dimensions were reconstructed and neonatal HC, as a proxy for fetal HC, was measured. The correlation between cases of CPD and cephalopelvic circumference index (CPCI), which represents the ratio between the HC and PC in percentage (HC/PC × 100), was evaluated. RESULTS: The mid-pelvis CPCI (MP-CPCI) was larger in CD groups as compared to the NVD group: 103 ± 11 versus 97 ± 8%, respectively (p = 0.0003). In logistic regression analysis, the MP-CPCI was found to be independently associated with CD due to CPD: each 1% increase in MP-CPCI increased the likelihood of CD for CPD by 11% (adjusted odds ratio [aOR] 1.11, 95% CI, 1.03-1.19, p = 0.004). The aOR for CD due to CPD increased incrementally as the MP-CPCI increased, from 3.56 (95% CI, 1.01-12.6) at MP-CPCI of 100 to 5.6 (95% CI, 1.63-19.45) at 105, 21.44 (95% CI, 3.05-150.84) at 110, and 28.88 (95% CI, 2.3-362.27) at MP-CPCI of 115. CONCLUSIONS: The MP-CPCI, representing the relative dimensions of the fetal HC and maternal PC, is a simple tool that can potentially distinguish between parturients at lower and higher risk of CPD. Prospective randomized studies are required to evaluate the feasibility of prenatal pelvimetry and MP-CPCI to predict the risk of CPD during labor.

PURPOSE: Endometrial scratching (ES) using a biopsy catheter prior to the IVF cycle in the repeated implantation failure (RIF) population has been suggested, but no convincing evidence of its benefit has been presented until now. METHODS: A retrospective mono-center study among 300 consecutive IVF-RIF cycles following evaluation of the ovarian reserve, hysterosalpingography or hysteroscopy, pelvic ultrasound, thrombophilia evaluation, karyotyping and assessment of male sperm parametrs. The findings within normal limits. All the patients offered ES, 78 consented and underwent ES prior to their next IVF cycle. RESULTS: A comparison of treatment outcomes between the post-ES cycles (n = 78) and the non-ES cycles (222) demonstrated the following: 34 (43.5%) versus 14 (6.3%) conceptions, respectively (p = 0.001) and 30 (38.4%) versus 2 (0.9%) clinical pregnancies, respectively (p < 0.001%), emphasizing an extremely high biochemical pregnancy rate among the non-ES cycles. Implantation rate was 19.7% versus 0.4%, respectively (p < 0.001) and live birth rate was 33.33% (26 newborns) versus 0.45% (1 newborn), respectively (p < 0.001). Since there were more embryos available for transfer and more top-quality embryos in the post-ES-IVF conception cycles, the role of ES became questionable. A multivariate analysis that included ES and the percentage of top-quality embryos demonstrated that ES was an independent factor highly correlated with conception in this particular RIF population. CONCLUSIONS: ES proved to be an efficient tool in a particular subgroup of RIF patients with fertility investigation results within normal limits, an optimal ovarian response to gonadotropins, and a high percentage of top-quality embryos. Nevertheless, the results should not be overestimated, since the study has limitations related to its retrospective model.

PURPOSE: To evaluate the characteristics of patients and IVF cycles with recurrent implantation failure who eventually succeeded to conceive compared to those who failed to do so. METHODS: In a retrospective study, we explored our database for patients younger than 35 years old who underwent at least three unsuccessful fresh IVF cycles. The following parameters were analyzed: cause of infertility, FSH level, stimulation cycle characteristics, fertilization rate, the type of luteal support, and cycle outcome. Uterine cavity assessment was also included. The relationship between endometrial scratching and the outcome of the following IVF cycle was assessed for the subsequent pregnancy rate. RESULTS: The study included 184 patients who underwent 854 IVF cycles. There were no statistically significant differences between patients who eventually conceived and those who did not in terms of ovarian reserve and response to gonadotropin treatment. IVF cycles that eventually ended with conception were characterized by shorter stimulation (10.87 ± 2.17 versus 11.34 ± 2.33 days, p < 0.05), higher estrogen level on the day of hCG administration (1661 ± 667 versus 1472 ± 633 pg/ml, p = 0.009), more fertilized oocytes via ICSI (5.04 ± 4.29 versus 3.85 ± 3.45, p = 0.002), and more embryos available for transfer (5.98 ± 3.89 versus 5.12 ± 3.31, p = 0.002). Combined estrogen and progesterone luteal support combined with endometrial scratching prior to the subsequent IVF cycle has been positively related to increased pregnancy rates. CONCLUSIONS: Young patients with RIF having a normal ovarian reserve and satisfactory ovarian response to superovulation should be encouraged to pursue IVF, even though the probability to conceive is relatively low compared to the general IVF population.

AIMS: To examine whether misoprostol treatment for first trimester missed abortion affects future fertility. PATIENTS AND METHODS: In a historical prospective approach, we analyzed our database for patients treated with misoprostol. All eligible patients underwent an interview according to a questionnaire, which includes their demographic characteristics, obstetric, gynecologic and infertility history. They were asked about the side effects, intention and subsequent ability to conceive. Their future pregnancy rates were calculated and compared to the acceptable figures in the literature. RESULTS: The infertility rates among our patients were similar to those reported in the general population. Pregnancy rates 2 years after treatment were similar to the previously published reports, except for lower rates during the first three months post-treatment. Although no between-group differences were observed in the subsequent pregnancy rates, 2 years following misoprostol treatment in ≤35 versus >35 years old patients, primi- versus multigravida and nulli- versus parous women, higher pregnancy rates were observed in patients ≤35 versus >35 years old, primi- versus multigravida and nulli- versus, parous, during the first 3 months following misoprostol treatment. CONCLUSION: Misoprostol treatment, for women with first trimester missed abortion and favorable reproductive history, is an acceptable treatment with no detrimental effect on future fertility.

OBJECTIVE: To compare perinatal outcome of deliveries complicated by cord prolapse between cases in which bladder filling was performed in addition to supporting presenting part and cases where only support was employed. MATERIALS AND METHODS: A retrospective review of 44 deliveries complicated by prolapse occurring after admission was made. The first group included 29 patients who were rushed to a cesarean section with doctor's hand inside the vagina pushing the presenting part. The second group of 15 patients, included women whose bladder was filled with 500 cc of normal saline in addition to manual support. RESULTS: Time to delivery was similar in the first and second group (19.7 ± 9.46 and 21.6 ± 11.9, P = 0.57; respectively) as well as the mean neonatal pH values (7.28 ± 0.09 and 7.26 ± 0.07, P = 0.55; respectively). There was no significant difference in proportion of neonates with an Apgar score of less than 7 between the two arms. CONCLUSION: The addition of bladder filling to further displace the presenting part did not improve the neonatal outcome which was not compromised regardless of the measures employed.
