Effects of the levonorgestrel-releasing intrauterine system plus estrogen therapy in perimenopausal and postmenopausal women: systematic review and meta-analysis.

Objective:The objective of this study was to compare the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) with those of systemic progestogen in perimenopausal and postmenopausal women taking systemic estrogen therapy (ET). Methods:We searched Medline (August 8, 2009), Embase (August 8, 2009), the Cochrane Central Register of Controlled Trials on the Cochrane Library Issue 3 (2009), the MetaRegister of Controlled Trials, and the reference lists of articles for relevant trials. Randomized controlled studies of LNG-IUS versus systemic progestogen in perimenopausal and postmenopausal women taking ET were included in the review. Two reviewers abstracted the trials independently. Any disagreement was resolved through discussion with the third reviewer. For dichotomous outcomes, a Peto odds ratio was calculated. For continuous outcomes, nonskewed data from valid scales were synthesized using a weighted mean difference or a standardized mean difference. Results:Six trials with a total of 518 participants were included. The methodological limitation was an attrition bias. In perimenopausal and postmenopausal women taking ET, the incidence of a proliferative endometrium was comparable between the use of systemic progestogen and LNG-IUS, except for sequential medroxyprogesterone acetate, which had a higher incidence of proliferative endometrium. Descriptive data synthesis showed that ET combined with either LNG-IUS or systemic progestogen effectively relieved climacteric symptoms. Vaginal bleeding and spotting were common in the LNG-IUS group for the first 3 to 6 months of use. The discontinuation rate was not different. There was insufficient evidence to draw any conclusions about the other outcomes. Conclusions:The LNG-IUS was more effective than sequential medroxyprogesterone acetate but was comparable with other systemic progestogen regimens for endometrial protection in perimenopausal and postmenopausal women taking ET.

Correlations of third-trimester hiatal biometry obtained using four-dimensional translabial ultrasonography with the delivery route in nulliparous pregnant women

Purpose: The goal of this study was to evaluate normal hiatal dimensions in the third trimester in nulliparous Thai pregnant women and to establish which biometric factors were associated with various pregnancy outcomes. Methods: Fifty-seven consecutive nulliparous pregnant Thai women in their third trimester were recruited on a voluntary basis from April to October 2014. All subjects underwent four-dimensional (4D) translabial ultrasonography. Hiatal biometric parameters were measured at rest, while performing a Valsalva maneuver, and during contraction. Information about the patients’ eventual deliveries was obtained from their medical records. Results: The mean values of the patients’ age, body mass index, and gestational age at the time of examination were 27.4±5.47 years, 26.7±3.48 kg/m2, and 36.6±1.49 weeks, respectively. No subjects had vaginal lumps or experienced prolapse greater than stage 1 of the Pelvic Organ Prolapse Quantification system. Ultrasonography showed that the mean values of the hiatal area at rest, while performing a Valsalva maneuver, and during contraction were 13.10±2.92 cm2, 17.50±4.81 cm2, and 9.69±2.09 cm2, respectively. The hiatal area at rest, the axial measurement at rest, and the axial measurement while performing a Valsalva maneuver were significantly associated with the route of delivery (P=0.02, P=0.04, and P=0.03, respectively). Conclusion: The route of delivery was associated with hiatal biometric values measured using 4D translabial ultrasonography, based on the results of nulliparous Thai women in the third trimester.

Incidence of and risk factors for febrile morbidity after laparoscopic-assisted vaginal hysterectomy

Background The purpose of this study was to assess the incidence of and risk factors for postoperative febrile morbidity after laparoscopic-assisted vaginal hysterectomy (LAVH). Methods This retrospective study was carried out using the medical records of women with benign gynecologic conditions who underwent LAVH between June 2007 and May 2012 at Srinagarind Hospital in Thailand. Data were collected to assess baseline patient characteristics, occurrence of body temperature ≥38°C on two occasions at least 6 hours apart in the 24 hours following the surgical procedure, and possible risk factors related to postoperative febrile morbidity. Results In total, 199 women underwent LAVH during the study period. They had a mean age of 46±6 years, a mean body mass index of 24.0±3.2 kg/m2, a mean surgical duration of 134±52 minutes, median estimated blood loss of 200 mL, a mean total hospital stay of 5±2 days, and a mean postoperative hospital stay of 3±2 days. Postoperative febrile morbidity was documented in 31 cases (15.6%). The cause of postoperative fever was unknown in most cases, with only two cases having an identifiable cause. The risk of postoperative febrile morbidity was highest in women treated with more than two antibacterial agents and with a regimen of more than 3 days. Conclusion This study shows a moderately high rate of febrile morbidity after LAVH, for which the main risk factors were use of multiple drugs and doses for antibiotic prophylaxis.
