The impact of sweeping the membranes on cervical length and labor: a randomize clinical trial
(2014) Parlakgumus, Huriye A.; Yalcinkaya, Cem; Haydardedeoglu, Bulent; Tarim, Ebru; 25322540
Objectives: The aim of the study was to investigate to what extent sweeping of the membranes contributes to cervical shortening and if cervical shortening is related to the time to onset of labor and duration of the active phase of labor. Methods: This prospective randomized clinical trial was performed at Baskent University between February and March 2011. Women were randomly assigned to receive membrane sweeping (Sweeping Group) (n=69) or no membrane sweeping (Control Group) (n=71). Cervical length was measured (cervix 1) in both groups by examiner 1 and the Bishap Score was determined in the control group and sweeping was performed in the sweeping group by examiner 2. Two days later the patients had another cervical length measurement (cervix 2) by examiner 1, blinded to the group and results of the examiner 2. t test, Mann-Whitney U test and Chi-square test were used for statistical analyses. Results: Cervix 1 was 27.4 +/- 8.4 mm and 29.6 +/- 8.9 mm (p = 0.14), cervix 2 was 23.3 +/- 8.8 mm and 23.8 +/- 8.5mm (p = 0.28) and cervical shortening was 5 +/- 4 mm and 5 +/- 4mm (p = 0.446), time to onset of labor was 6.3 +/- 4.6 and 5.7 +/- 4.1 (p = 0.38) and duration of labor was 5.8 +/- 2.89 and 5.7 +/- 2.4 (p = 0.82) for the sweeping and the control groups, respectively. Conclusions: Sweeping of the membranes does not reduce cervical length and does not shorten time to onset of labor and duration of the active phase of labor.

Objective: To report cases who were suspected to have mature cystic teratoma in the preoperative and intraoperative periods, but were found to have malignancy together with mature cystic teratoma in the final histopathological examination. Materials and Methods: The medical records of 148 cases were retrieved. The records were used to review the sociodemographic properties, histopathology, intraoperative tumor size, the surgical procedure, adjuvant therapy, and follow-up of the patients who were suspected to have mature cystic teratoma in the preoperative and intraoperative periods, but were found to have malignancy together with mature cystic teratoma in the frozen or final histopathological examination. Results: Of the patients, 8.2% were found to have malignancy arising in mature cystic teratoma. The median age of the patients was 32- (min: 15, max: 66) years-old and the tumor size was 12.1 (min: 4, max: 25) cm. Six patients were established to have an immature teratoma, three had a carcinoid tumor, one had a primitive neuro-extrodermal tumor (PNET), one had serous borderline tumor, and one had a borderline mucinous tumor. Conclusion: Although a mature cystic teratoma is benign, since it may involve different degrees of malignancy, intraoperative attitudes and procedures should follow the rules that apply to the management of a complicated adnexal mass and the possibility of a malignant transformation should be in kept in mind when informing the patient in the preoperative period.
