Arabin-pessary or McDonald Cerclage in Cervical Shortening? / Pessário de Arabin ou cerclagem McDonald no encurtamento cervical?

Abstract Objective The aim of the present study is to compare the effectiveness of Arabin pessary and McDonald cervical cerclage on preterm delivery. Methods We conducted a retrospective analysis of data from patients who underwent either Arabin pessary or McDonald cerclage between January 1, 2019, and January 1, 2023. A total of 174 patients were included in the study, with 31 undergoing Arabin pessary and 143 receiving cervical cerclage using the McDonald technique in singleton pregnant women with cervical insufficiency, which applied between 14 and 22 gestational weeks. We included singleton pregnant women with normal morphology, and with normal combined test. The primary outcome was the impact of each method on preterm delivery (< 34 gestational weeks). Results The weeks of cervical cerclage or pessary application were compatible with each other (p< 0.680). The pessary group had a statistically significant longer time to delivery compared with the Cerclage group (cerclage group mean 30.8 c 7.1 standard deviation [SD] versus pessary group mean 35.1 ± 4.4 SD; p< 0.002). A statistically significant difference was found between the pessary and cerclage groups in terms of delivery at < 34 weeks (p= 0.002). In patients with cervical length between 25 and 15mm and < 15mm, no significant difference was found between the pessary and cerclage groups in terms of delivery week (p< 0.212; p< 0.149). Regardless of the technique applied, no statistically significant difference was observed between cervical length and birth < 34 weeks. Conclusion Our study found that pessary use for cervical insufficiency is statistically more effective than cervical cerclage surgery in preventing preterm births < 34 weeks in singleton pregnancy.

Molecular detection of cytomegalovirus, herpes simplex virus 2, human papillomavirus 16-18 in Turkish pregnants

OBJECTIVE: Human cytomegalovirus (CMV) is the most common cause of viral intrauterine infections in the world. Herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) are the main agents of viral sexually transmitted diseases, which cause genital ulcers and genital warts, respectively. HPV infection has been linked to the majority of the anogenital malignancies. The aim of this study was to detect the existence of CMV, HSV-2 and HPV type 16-18 in Turkish pregnants by using sensitive molecular assays. METHODS: One hundred thirty-four women (18-41 years old; mean age ± SD: 27 ± 8) applied to outpatient clinic of Obstetrics and Gynecology, in between 18th - 22nd weeks of their pregnancy and a control group of 99 healthy women (15-39 years old; mean age ± SD: 24 ± 8) were included in the study. Cervical smear samples were used for DNA extraction. CMV, HSV-2 and HPV 16-18 detections were carried out by real time PCR and in house PCR method, respectively. RESULTS: Three patients (3/134; 2.2 percent) were found to be positive for each HPV and HSV-2. Dual infection with HPV and HSV was found in just one patient. HPV 18 was detected in all positive samples. CMV was found to be positive in two patients (2/134; 1.4 percent). CONCLUSION: HPV, HSV and CMV must be screened due to high prevalence of these viruses in pregnants by using sensitive molecular methods.

Prevalence of human papillomavirus (HPV) and HPV-16 genotyping by real-time PCR in patients with several cervical pathologies.

PURPOSE: this study was planned to evaluate the prevalence of HPV (excepting type 16) and HPV 16 by real-time PCR in colposcopy patients and to interprete the results with age, age of first sexual intercourse (FSI), parity and Pap smear results. METHODS: one hundred and two colposcopy patients (50 and 52 of the patients were classified as colposcopy positive and negative, respectively) applying to Gynecology clinic were included. HPV (excepting type 16) and HPV 16 were detected by realtime PCR using the L1 region. Real-time nested amplifications of MY09/11 products were done by GP5+/GP6+ primers and Cyanine-5 labeled HPV and HPV 16 DNA specific probe after HPV DNA extraction by phenol chloroform isoamylalcohol. RESULTS: HPV (excepting type 16) and HPV 16 were positive in 12% and 18% of the colposcopy positive patients respectively. HPV (excepting type 16) and HPV 16 were positive in 5.7% and 3.8% of the colposcopy negative patients, respectively. CONCLUSION: there was a statistically significant difference between colposcopy positive and colposcopy negative patients comparing HPV 16 with total HPV positivity (p = 0.021 for type 16 and p = 0.010 for total HPV) but there was not a statistically significant difference between colposcopy positive and colposcopy negative patients when we compared HPV (excepting type 16) positivity (p = 0.314). In conclusion, HPV detection and typing may be helpful for cervical cancer screening and prevention.
