Evaluation of concordance between loop electrosurgical excisional procedure and cervical colposcopic biopsy results

Objective: To evaluate the results of loop electrosurgical excisional procedures (LEEP) with colposcopic biopsy results of patients who presented to our hospital for vaginal smears. Material and Methods: The LEEP reports of patients who presented to our gynecology clinic between January 2015 and December 2020 were retrospectively evaluated. The data were obtained from electronic patient records and the department of medical pathology archives. Results: A total of 579 patients were evaluated with a mean age of 38.05±6.17 years. Colposcopy-guided biopsy was not taken from 102 patients. The results of the remaining 477 (82.4%) patients were: no dysplasia (n=12; 2.1%), Cervical intraepithelial neoplasia-I (CIN-I) (n=99; 17.1%), CIN-II (n=111; 19.2%), CIN-III (n=248; 42.8%), and cancer (n=7; 1.2%). Completed excision was performed in 87.0% of the patients using LEEP, the lesion was positive at the surgical margins in 10.9%, and the lesion could not be completely excised in 2.1%. The complication rate after LEEP was 3.1% including pelvic pain (n=5; 0.9%) and bleeding (n=13; 2%). The histopathologic results of LEEP were: benign (n=50; 8.6%), CIN-I (n=110; 19.0%), CIN-II (n=89; 15.4%), CIN-III (n=280; 48.4%), cancer (n=7; 1.2%), and metaplasia (n=37; 6.4%). The concordance between colposcopic biopsy and LEEP results was 85.9% for CIN-I, 71.2% for CIN-II, 98.4% for CIN-III, and 85.7% for cancer diagnoses. Conclusion: LEEP is a simple minimally invasive method used in the treatment of CIN, with low persistence, recurrence, and complication rates and increased human papillomavirus clearance in most patients. Our results support the consistency of cervical colposcopic biopsy and LEEP results.

The effect of embryo transfer technique on pregnancy rates in in vitro fertilization-intracytoplasmic sperm injection cycles: A prospective cohort study.

OBJECTIVE: To investigate whether embryo transfer affects pregnancy rates in in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) treatment. MATERIALS AND METHODS: A total of 2,257 patients who underwent IVF-ICSI treatment between 2012 and 2017 were included in this study. Subjects were categorized according to the embryo transfer technique that was required: group 1 (n=1,657) underwent easy transfer with a soft catheter; group 2 (n=548) received external guidance transfers; and group 3 (n=52) experienced difficult transfers with a stylet. Basal parameters, clinical and laboratory IVF-ICSI outcomes, and clinical pregnancy rates (CPR) were compared between the groups. RESULTS: There were no differences between the groups in terms of age, body mass index, smoking status, duration and etiology of infertility, baseline follicle-stimulating hormone, luteinizing hormone, estradiol (E2), thyroid-stimulating hormone, prolactin levels, antral follicle count, duration of stimulation, stimulation protocol, total gonadotropin dose required, peak E2 levels, progesterone levels, and endometrial thickness on human chorionic gonadotropin administration and transfer days (p>0.05). The numbers of oocytes retrieved, MII and 2PN, fertilization rate, day of embryo transfer, and CPRs were also comparable between the groups (p>0.05). CONCLUSION: Our data suggest that embryo transfer has no impact on pregnancy rates in patients who undergo IVF-ICSI treatment. Further studies with more participants are required to elucidate this situation.

Assessment of circulating betatrophin levels in intrahepatic cholestasis of pregnancy.

Objective: To investigate maternal serum levels of betatrophin and their relationship with total bile acid (TBA) levels in patients with intrahepatic cholestasis of pregnancy (ICP).Materials and methods: Fifty-nine pregnant women with ICP (31 patients with severe and 28 patients with mild disease classifications) and 23 healthy women with uncomplicated pregnancies as the control group included the study. The maternal betatrophin, fasting blood glucose, fasting insulin (FI), and homeostatic model assessment of insulin resistance (HOMA-IR) levels of the groups were compared.Results: Serum betatrophin levels were significantly higher in the ICP groups than in the control group (p = .04 and p < .001, respectively). The FI levels and HOMA-IR values were significantly higher in the severe ICP group than in the control group (p = .006 and p = .001, respectively). While a significant positive correlation was found between betatrophin levels and fasting and postprandial TBA levels, there was no significant correlation among betatrophin and HOMA-IR or FI levels.Conclusions: Betatrophin levels were shown to correlate with TBA levels, it provides a model for future studies to understand the physiopathology of ICP, a complex metabolic disease. Changes in betatrophin levels may shed light on the pathogenesis of ICP.

Are there any differences between antagonist administration on days <6 and ≥6 of Controlled Ovarian Hyperstimulation on assisted reproductive technique outcomes?

BACKGROUND: The aim of this study was to investigate the cost-effectiveness of antagonist administration on stimulation on days <6 and ≥6 of COH on assisted reproductive technique (ART) outcomes. METHODS: In this retrospective cohort study, 412 patients who were admitted to the ART Department were evaluated. In group 1 (203 patients), antagonist administration was provided on days <6 of COH. For group 2 (209 patients), antagonist administration was provided on days ≥6 of COH. We preferred a flexible antagonist protocol in clinical practice and added an antagonist treatment regimen when dominant follicles were enlarged to 13 mm or the serum blood E2 was >300 pg/mL. RESULTS: There were no differences between antagonist administration on days <6 and days ≥6 of COH in terms of age, BMI, duration and etiology of infertility, AFC, serum FSH, LH, peak E2 levels, the number of MII oocytes, 2PN, FR, the number of transferred embryos, and CPR per woman. However, there were statistically significant differences between the duration of stimulation, the total gonadotropin dose required, and progesterone levels on day hCG [8.26 ± 1.83 vs 9.56 ± 1.51 (p = 0.001); 2173.71 ± 860.00 vs 2749.17 ± 1079.51 (p = 0.001); 0.75 ± 0.44 vs 0.92 ± 0.59 (p = 0.002), respectively]. CONCLUSION: Our results have demonstrated that there was no effect of antagonist administration on days <6 and ≥6 of COH on ART outcomes. However, taking cost-effectiveness into consideration, we suggest an antagonist administration on days <6 of COH since the necessary gonadotropin dose is lower.

Comparison of vaginal misoprostol and dinoprostone for cervical ripening before diagnostic hysteroscopy in nulliparous women.

OBJECTIVE: To compare the effectiveness of vaginal misoprostol and dinoprostone for cervical ripening before diagnostic hysteroscopy in nulliparous women. DESIGN: Placebo-controlled, double blind, randomized trial. SETTING: Teaching and research hospital. PATIENT(S): Ninety women of reproductive age eligible for diagnostic hysteroscopy. INTERVENTION(S): Randomly assignment to receive 400 µg of misoprostol (n = 30) or 10 mg of dinoprostone (n = 30) vaginally before diagnostic hysteroscopy, with a control group (n = 30) not receiving any cervical priming agent. PRIMARY OUTCOME: the number of women requiring cervical dilatation; secondary outcomes: cervical width before surgery, duration of dilatation time, ease of dilatation, complications during surgical procedure, and side effects of the drugs. RESULT(S): In the placebo group, 23 patients required cervical dilatation compared with 17 in the misoprostol group and 9 in the dinoprostone group. The mean (± standard deviation) cervical widths for the placebo, misoprostol, and dinoprostone groups were 4.23 ± 0.43 mm, 5.43 ± 0.5 mm, and 5.83 ± 0.64 mm, respectively. These widths were statistically significantly different. The duration of dilatation was also statistically significantly longer in the control group. CONCLUSION(S): Vaginally administered dinoprostone before diagnostic hysteroscopy is more effective than misoprostol for inducing cervical priming. Further studies are required to elucidate the most efficient option with the least side effects for cervical ripening. CLINICAL TRIAL REGISTRATION NUMBER: NCT01620814.
