Rotational forceps versus manual rotation and direct forceps: A retrospective cohort study.

Objective: Rotational forceps and manual rotation followed by direct forceps are techniques used in the management of malposition of the fetal head in the second stage of labor. However, there is widespread debate regarding their relative safety and utility. We aimed to compare the effectiveness and safety of rotational forceps with manual rotation followed by direct forceps, for management of fetal malposition at full dilation.

Hybrid simulation compared to manikin alone in teaching pelvic examinations: a randomised control trial.

Introduction: Performing a pelvic examination is a core skill for all medical undergraduates. The use of hybrid simulation, manikin with patient actress, to attain technical and communication skills competencies and to improve the quality of care we offer women, has not been compared to other teaching methods before. Outcome measures were technical skills, communication skills and confidence in completing a pelvic examination.

Using singing to nurture children's hearing? A pilot study.

This article reports a pilot study of the potential benefits of a sustained programme of singing activities on the musical behaviours and hearing acuity of young children with hearing impairment (HI). Twenty-nine children (n=12 HI and n=17 NH) aged between 5 and 7 years from an inner-city primary school in London participated, following appropriate ethical approval. The predominantly classroom-based programme was designed by colleagues from the UCL Institute of Education and UCL Ear Institute in collaboration with a multi-arts charity Creative Futures and delivered by an experienced early years music specialist weekly across two school terms.

Modified obstetric early warning scoring systems (MOEWS): validating the diagnostic performance for severe sepsis in women with chorioamnionitis.

Objective: We sought to compare the predictive power of published modified obstetric early warning scoring systems (MOEWS) for the development of severe sepsis in women with chorioamnionitis.

Study Design: This was a retrospective cohort study using prospectively collected clinical observations at a single tertiary unit (Chicago, IL). Hospital databases and patient records were searched to identify and verify cases with clinically diagnosed chorioamnionitis during the study period (June 2006 through November 2007).

Realism and construct validity of novel pelvic models of common gynecologic conditions.

Objective: To test a novel set of pelvic trainers for realism and construct validity.

Methods: Seven models of the female pelvis were studied. Participants performed speculum and bimanual examinations, documented their findings, and recorded opinions of the models in a structured questionnaire.

Reducing risk in maternity by optimising teamwork and leadership: an evidence-based approach to save mothers and babies.

Poor teamwork results in preventable morbidity and mortality for mothers and babies. Suboptimal communication and lack of leadership cost not only lives but also money that is diverted from clinical care to insurance and litigation. Avoidable harm is usually not the result of staff failing their duty of care, it is the result of poor training failing hard-worked staff.

Brown-Vialetto-Van Laere syndrome, a ponto-bulbar palsy with deafness, is caused by mutations in c20orf54.

Brown-Vialetto-Van Laere syndrome is a rare neurological disorder with a variable age at onset and clinical course. The key features are progressive ponto-bulbar palsy and bilateral sensorineural deafness. A complex neurological phenotype with a mixed picture of upper and lower motor neuron involvement reminiscent of amyotrophic lateral sclerosis evolves with disease progression.

Voriconazole therapy in children with cystic fibrosis.

Background: There is increasing evidence for the efficacy of the antifungal voriconazole, particularly in immunosuppression. We describe our experience of using voriconazole in children with CF.

Methods: We performed a retrospective case note review of children with CF treated with voriconazole in a single centre over an 18 month period.

Transgenes encompassing dual-promoter CpG islands from the human TBP and HNRPA2B1 loci are resistant to heterochromatin-mediated silencing.

The genetic elements that are responsible for establishing a transcriptionally competent, open chromatin structure at a region of the genome that consists only of ubiquitously expressed, housekeeping genes are currently unknown. We demonstrate for the first time through functional analysis in stably transfected tissue culture cells that transgenes containing methylation-free CpG islands spanning the dual divergently transcribed promoters from the human TATA binding protein (TBP)-proteasome component-B1 (PSMB1) and heterogeneous nuclear ribonucleoprotein A2/B1 (HNRPA2B1)-heterochromatin protein 1Hs-gamma (chromobox homolog 3, CBX3) gene loci are sufficient to prevent transcriptional silencing and a variegated expression pattern when integrated within centromeric heterochromatin. In addition, only transgene constructs extending over both the HNRPA2B1 and the CBX3 promoters, and not the HNRPA2B1 promoter alone, were able to confer high and stable long-term EGFP reporter gene expression.

Redox poise and oxygenation of cytochrome bd in the diazotroph Azotobacter vinelandii assessed in vivo using diode-array reflectance spectrophotometry.

A ferrous oxygenated form of cytochrome d is characteristic of all cytochrome bd-type oxidases so far examined, but its participation in enzyme turnover is unclear. It is relatively stable, occurs in aerated cell suspensions and predominates during enzyme preparation. In this study, diode-array reflectance spectrophotometry was used to assess the redox poise and oxygenation of cytochrome bd in vivo, in the aerobic diazotroph Azotobacter vinelandii.
