Randomised trial of assigned mode of delivery after a previous cesarean section--impact on maternal psychological dynamics.

Objective: This randomised trial was designed to study the psychological status and morbidity during and after delivery among women with a previous cesarean section (CS) who were randomised to planned vaginal birth (VBAC) or planned CS.

Methods: Two hundred and ninety-eight women with one previous lower segment CS were randomised to either planned VBAC or planned CS. Women were asked to complete psychometric scales during their pregnancy till 6 months after confinement.

Sociodemographic factors and pregnancy events associated with women who declined vaginal birth after cesarean section.

Objective: Certain sociodemographic characteristics and pregnancy events were shown to pre-dispose women to decline vaginal birth after cesarean section (CS) in the Western population. The study aimed to identify the sociodemographic factors and pregnancy events associated with Chinese women who declined to attempt vaginal birth after CS.

Study Design: This was a retrospective study of Hong Kong Chinese women who delivered in a public obstetric unit between 2002 and 2006.

Dysregulated microRNAs and their predicted targets associated with endometrioid endometrial adenocarcinoma in Hong Kong women.

The objective of this study, a parallel study to global gene expression profiling, was to identify dysregulated microRNAs (miRNAs) associated with endometrioid endometrial adenocarcinoma (EEC), examine their correlation with clinico-pathological characteristics and identify predicted target genes of the dysregulated miRNAs. Using real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR), profiling of miRNA expression was performed in 30 EECs and 22 normal counterparts in which genome-wide gene expression had been previously profiled and reported. Clustering analysis identified 30 miRNAs which were significantly dysregulated in EEC.

Impact of first childbirth on changes in women's preference for mode of delivery: follow-up of a longitudinal observational study.

Background: A woman's childbirth experience has an influence on her future preferred mode of delivery. This study aimed to identify determinants for women who changed from preferring a planned vaginal birth to an elective cesarean section after their first childbirth.

Methods: This prospective longitudinal observational study involved two units that provide obstetric care in Hong Kong.

Measurement of tension-free vaginal tape trocar insertion and exit forces.

Background/aims: This study aims to establish a model to measure the forces required for tension-free vaginal tape (TVT) trocar application using a pressure transducer.

Methods: A 3.5 x 3.

Changing prevalence and knowledge of urinary incontinence among Hong Kong Chinese women.

A territory-wide telephone survey was conducted in Hong Kong to assess the prevalence, knowledge, and treatment-seeking behaviour of Chinese women with urinary incontinence, using validated Chinese version of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Women, 540, aged between 17 to 77 years were interviewed. Of the respondents, 40.

Placental transfer of Zidovudine in first trimester of pregnancy.

Objective: Zidovudine is one of the most common antiretroviral drugs used to prevent vertical transmission of human immunodeficiency virus. However, it is not recommended for use in the first trimester of pregnancy because of reservations about its potential teratogenicity during the organogenesis phase. The objective of this study was to investigate the placental transfer of zidovudine in the first trimester of human pregnancy.

Impact of hypertensive disorders of pregnancy at term on infant birth weight.

This study was performed to investigate the impact of hypertensive disorders of pregnancy at term on neonatal birth weight. All singleton live births delivered between 37 and 42 weeks of gestation complicated by hypertensive disorders over a 7-year period (n = 362) was compared to 34 783 uncomplicated singleton deliveries in the same period. The individualized gestation-related optimal weight (GROW) was calculated for each individual case adjusted for the effects of maternal booking weight, height, parity, gestation at delivery, and fetal sex.

Screening test model using duration of labor for the detection of postpartum urinary retention.

Aims: To construct a screening test model for postpartum urinary retention (PUR), using the duration of labor, which was shown to be the risk factor for PUR.

Methods: A group of 691 consecutive patients were recruited at postpartum day 1. Of the 691 patients, 101 (14.

A study of female urinary tract infection caused by urodynamic investigation.

Objective: The purpose of this study was to assess the prevalence of female urinary tract infection before and after urodynamic investigation and to identify the risk factors for urinary tract infection after urodynamic investigation.

Study Design: Eight hundred twenty-two consecutive incontinent women were recruited. All women were "double-screened" and treated for urinary tract infection before urodynamic investigation: first by mid stream urine culture 4 to 6 weeks before investigation and then by reagent strips for urine leukocytes and nitrites at the time of investigation.

Effects of aging on generic SF-36 quality of life measurements in Hong Kong Chinese women with urinary incontinence.

Background: To evaluate the relationship between aging, urodynamic diagnosis and generic quality of life measurement in Chinese women with urinary incontinence.

Methods: A total of 170 women presented to a university teaching hospital with urinary incontinence were recruited. The women completed the medical outcome survey, short form-36 (SF-36), immediately before they had the urodynamic investigation.

Arcus tendineus levator ani tear causing pelvic hematoma after tension-free vaginal tape insertion.

Although vaginal tamponade is usually sufficient for hemostasis, it is not useful if a pelvic hematoma occurs. Here, we report the unusual case of a large pelvic hematoma necessitating laparotomy for hemostasis due to a tear of the arcus tendineus levator ani after insertion of a tension-free vaginal tape.
