Comparison of fixed and flexible progestin-primed ovarian stimulation protocols to prevent premature luteinization in patients with diminished ovarian reserve.

PURPOSE: Flexible progestin-primed ovarian stimulation (PPOS) protocol is demonstrated to be effective in suppressing premature luteinization in few studies. We aimed to compare fixed and flexible PPOS protocols in preventing premature luteinization in patients with diminished ovarian reserve. METHODS: This retrospective cohort study included patients with a diminished ovarian reserve who were administered PPOS protocols for pituitary suppression during ovarian stimulation in a tertiary center in between January 2019 and June 2022. At fixed protocol, 20 mg/day dydrogesterone was started in cycle day two or three along with gonadotropins and continued until trigger day. In contrast, at flexible protocol, 20 mg/day dydrogesterone was commenced when the leading follicle reached 12 mm or serum estradiol (E2) level was > 200 pg/mL. RESULTS: A total of 125 patients, of whom 83 were administered fixed PPOS protocol and 42 were administered flexible PPOS protocol, were included in the analysis. Both groups had similar baseline characteristics and cycle parameters, including total days of gonadotropin administration and total gonadotropin dose (p > 0.05). Premature luteinization occurred at 7.2% and 11.9% of patients in fixed and flexible PPOS protocols, respectively (p = 0.505). Retrieved oocytes numbers, metaphase II oocyte numbers, and 2PN numbers were also similar (p > 0.05). Clinical pregnancy rates per transfer were 52.5% in fixed and 36.4% in flexible protocols (p = 0.499). CONCLUSION: Both fixed and flexible PPOS protocols had statistically similar outcomes in preventing premature luteinization and other cycle parameters. The flexible PPOS protocol seems to be as effective as the fixed PPOS protocol for patients with diminished ovarian reserve; however, further prospective studies should be conducted to validate the results of our research.

Cervical cancer is the fourth most common cancer among women all over the world. It is accepted that cervical cancer is highly related to the HPV. The International Agency for Research on Cancer (IARC) has classified 13 HPV types as group 1 carcinogens (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 66), which are commonly referred to as high risk-HPVs (hr-HPVs). Among these, hr-HPV-16 is undoubtedly the most carcinogenic based in the burden of cervical cancer (CC) and its precursor lesions. In our study, we analyzed retrospectively the data of a total of 2329 female patients who applied to the obstetrics and gynecology outpatient clinic of our hospital over a seven-year-period, whose cervical smear were carried out by the polymerase chain reaction (PCR) and cytology. In this study, it was aimed to determine the data of of HPV prevalence in our region during the seven-year-period from April 2014 to April 2021 and the most common genotypes and to interpret them together with the cervical smears cytology and biopsy results if it is available. HPV 3, 6, 11, 16, 18, 21, 26, 31, 33, 35, 39, 40, 42, 45, 51, 52, 53, 54, 55, 56, 58, 59, 61, 62, 66, 67, 68, 70, 72, 73, 81, 82, 83, 84 were identified by using linear array HPV genotyping test (Roche Diagnostics, Switzerland) from April 2014 to October 2017. HPV genotypes were identified by using HPV Genotypes 14 Real-TM Quant (Qiagen, Germany) between October 2017 and April 2021. This method detected HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68. The data were analyzed using IBM SPSS Statistics (Version 25.0) predictive analytics software. Continuous variables are indicated as mean ± standard deviation, and discrete variables are indicated as number [percentage (%)]. Chi-square test is used to investigate dependencies between variables. All analyzes were evaluated to provide 95% confidence level and 80% test power. p<0.05 was accepted as significant for the analysis results. Out of 2329 patients, 1283 were found to be HPV negative (54.6%) and the others were found to be HPV positive (45.4%) by using real-time PCR in the cervical smears. It was detected that out of 1046 HPV positive patients, 585 of them (55.9%) had one HPV genotype and 461 of them (44.1%) had more than one HPV genotypes. As we divided all of the patients into two groups as <30 (Group I) ve > 30 (Group II) according to age range, HPV positivity was found 134/296 (45.2%) in Group I and 912/2033 (44.8%) in Group II. When we compared the HPV positive/negative results of Groups I and II by using chi-square test, no significant difference was found between the two age groups in terms of HPV positivity (p= 0.894). In our study, the most common HPV types were HPV 16 (14.2%), HPV 68 (8.2%), HPV 56 (8.2%), HPV 52 (7.1%), HPV 51 (6.8%), HPV 31 (6.5%), HPV 66(6.1%), HPV 39 (5.8%) and HPV 18 (5.6%) among the women with normal and abnormal cytology in the cervical smears. ASC-US was the most common abnormal epithelial cell change detected with HPV16 and 18 genotypes and it was detected 26.07% and 21.88% in patients, respectively. In our study, we found HPV prevalance in our region as 45.4% and the most common type was HPV 16. As a result, we concluded that it is important to determine regional HPV prevalance data, which is an important step in cervical cancer prevention strategies, and regional data of detected HPV genotypes.

The effect of suture materials with different absorption times on isthmocele: a retrospective study.

OBJECTIVES: With the increasing rate of cesarean operations, the formation of niches and related early and late complications have been observed more frequently. In this study, we examined the effects of using a suture material that can be absorbed faster than conventional sutures on the formation of niches. MATERIAL AND METHODS: This study was designed as a retrospective study and completed with a total of 101 patients. During the cesarean operation, the uterus was closed with Rapide Vicryl® in 49 patients and Vicryl® in 52 patients. The uterine niche was measured with a sonohysterogram 6 months after the operation. The primary outcome of the study was determined as uterine niche formation and the secondary outcome was the post-menstrual spotting (PMS) rate. RESULTS: Duration of surgery, intraoperative/postoperative blood loss, and hospitalization time were similar between the two groups. Niche formation was significantly lower in the Rapide Vicryl group (22.4%) when compared to the Vicryl group (42.3%) (p = 0.046). Also, PMS was observed significantly lower in the Rapide Vicryl group (16.2% and 52.8% in Rapide Vicryl and Vicryl groups, respectively; p = 0.002). CONCLUSIONS: The formation of niches and associated PMS rates were less with suture materials that were absorbed faster.

Intrahepatic cholestasis of pregnancy: are in vitro fertilization pregnancies at risk?

AIM: Single pregnancy patients with intrahepatic cholestasis of pregnancy (ICP) were divided into two groups according to the conception method, as spontaneous and in vitro fertilization (IVF). We aim to compare the maternal, laboratory and perinatal characteristics of both groups. MATERIALS AND METHOD: The records of 10,929 patients who gave birth in the center between October 2011 and July 2019 were analyzed retrospectively from the data processing system records. Maternal, laboratory and perinatal characteristics of 109 single pregnancies (spontaneous n: 91; IVF n: 18) diagnosed with ICP were compared. FINDINGS: The maternal demographic data of both groups were similar (p: .05). In both groups, gestational week, gestational age at birth, birth weight, neonatal intensive care admission rate, meconium-stained amniotic fluid, umbilical cord pH, the 5-minute APGAR score, and the presence of pregnancy complications were similar (p > .05). RESULT: Although ICP is reported with a higher incidence in IVF pregnancies, ICP findings and prognosis are similar to those of spontaneous pregnancies.

Laparoscopic para-aortic lymphadenectomy: Technique and surgical outcomes.

OBJECTIVE: Pelvic and para-aortic lymph node dissection is an important part of staging surgery. Aim of this study is to evaluate perioperative outcomes of patients, who underwent laparoscopic para-aortic lymphadenectomy for gynecological cancer in a single center over a period of 7 years, based on body mass index (BMI), and to present the surgical technique in steps. METHODS: Data of patients who underwent para-aortic lymphadenectomy at gynecological oncology department of a tertiary center in between March 2013 and July 2020 were analyzed retrospectively. Patients were evaluated in two groups according to their BMI (< 30 kg/m2 as non-obese and ≥ 30 kg/m2 as obese groups). Surgical technique is described in steps. Perioperative outcomes of the two groups were evaluated. RESULTS: A total of 230 patients were included in the study. BMI was ≥30 at 58.46 % of the patients. Peri-operative features were not significantly affected by the patient's BMI with the presented surgical technique, however, collected para-aortic lymph node numbers were higher in the group with BMI < 30, though sufficient number of lymph nodes were achieved in both groups. CONCLUSION: Although some technical difficulties may be encountered, laparoscopic para-aortic lymphadenectomy is feasable in gynecologic oncological surgery independent of BMI. However, surgical experience is important.

Outcomes of cesarean scar pregnancy treatment: Do we have options?

Objective: To investigate the success and complications of medical and surgical modalities used in the treatment of cesarean scar pregnancies. Materials and Methods: Medical and surgical approaches that have been used to treat cesarean scar pregnancies were evaluated retrospectively, Local, systemic, and combined methotrexate treatments were grouped as the medical approach, and dilatation and evacuation, hysteroscopic resection, laparoscopic and laparotomic approaches were grouped as the surgical approach. Fifty-three patients were diagnosed as having cesarean scar pregnancy during the study period, 48 of whom were included in the final analysis. Eighteen patients were treated with medical interventions and 30 patients were treated surgically. Results: The success rate of surgical modalities was 96.6% and the medical treatment success was 33% (p<0.001). The complication rate was higher with medical approaches compared with surgical methods (66% vs 3.3%, respectively; p<0.001). Conclusion: Surgical intervention seems safer and more successful than medical treatment.
