Implementation Challenges in Translating Pivotal Response Training into Community Settings

Implementing evidence-based practices (EBPs) for children with autism is challenging for teachers because these practices are often complex, requiring significant training and resources that are not available in most school settings. This brief investigation was designed to identify areas of strength and difficulty for teachers implementing one such EBP, pivotal response training (PRT). Observational data were gathered from 41 teachers participating in two separate investigations involving PRT. Despite differences in training procedures, teachers demonstrated similarities in areas of strength (clear opportunities/instruction and child choice) and difficulty (turn taking and multiple cues). These findings suggest next steps toward systematic adaptation of PRT for classroom use. The research may serve as a model for the process of adapting EBPs for practice settings.     

Residency Training in Emergency Ultrasound: Fulfilling the Mandate

Although bedside ultrasound is listed in the Model of the Clinical Practice of Emergency Medicine as an integral diagnostic procedure, the manner in which the didactic, hands-on, and experiential components of emergency ultrasound are taught is not specifically prescribed by the Residency Review Committee for Emergency Medicine (RRC-EM) or any single sponsoring group. Seven professional organizations [the American Board of Emergency Medicine (ABEM), the American College of Emergency Medicine (ACEP), the Council of Emergency Medicine Residency Directors (CORD), the Emergency Medicine Residents Association (EMRA), the National Association of EMS Physicians (NAEMSP), the RRC-EM, and the Society for Academic Emergency Medicine (SAEM)] developed the Scope of Training Task Force, with the goal of identifying emerging areas of clinical importance to the specialty of emergency medicine, including emergency department (ED) ultrasound. The Task Force then identified a group of recognized authorities to thoughtfully address the issue of ED ultrasound training. This report represents a consensus of these identified experts on how emergency ultrasound training should be incorporated into emergency medicine residency programs.     

Versagensgründe von Oberflächenersatzimplantaten der Hüfte

Hip resurfacing has been experiencing a revival over the last 5-10 years. Early failure rates are higher than for conventional primary hip arthroplasty. Fractures of the femoral neck or head, cup loosening and persistent pain are the most frequently observed reasons for early revision. In this international retrospective uncontrolled study, 256 revision specimens (219 resurfacing heads, 37 cups) were analysed radiologically, tribologically, morphologically and histologically in order to investigate the failure mechanism. Of the head revisions, 70% were due to neck (median: 67 days after implantation) and head fractures (161 days), 9% were due to cup loosening (350 days) and 21% due to other reasons (602 days). Implants with rim loading (22% of all retrievals, cup inclination 58.0+/-10.9 degrees ) exhibited a head wear rate of 7.1+/-5.2 mm3/year. Non-rim loaded implants exhibited a head wear rate of 0.24+/-0.53 mm3/year (cup inclination 49.0+/-4.0 degrees ). The failure rate was highest during the first 16 weeks after surgery and for the first ten operations performed by a surgeon. Revisions based on problems on the femoral side such as notching and high implantation forces occurred earlier than revisions based on problems on the acetabular side such as cup loosening and high wear due to suboptimal cup position.     

Prevalence of vaginal infections and associated lifestyles of students in the university of Cape Coast,Ghana

Objective

To determine the prevalence of vaginal infections and associated lifestyles of students visiting the University of Cape Coast Hospital.

Methods

Fifty female students presenting with clinical symptoms of vaginitis were sampled. One hundred samples made up of 50 urine and 50 higher vaginal swabs (HVS) were obtained from patients and questionnaire administered. Samples were wet prepared, examined microscopically, and cultured on blood and chocolate agars for 24 h at (35±2) °C. Colonial morphology, Gram reactions and biochemical tests were used for the identification of isolates.

Results

There were high percentages of pus cells (64%), epithelial cells (62%) and yeast cells (56%) in all urine samples. Bacterial isolates included Staphylococcus aureus (28%) and (22%), Klebsiella spp. (6%) and (4%) in urine and HVS samples respectively; Escherichia coli in urine (18%) and Candida in HVS (16%). The overall prevalence of vaginitis was 66%, including bacterial vaginosis 28%, Candida infection 22% and co-infection of bacterial and Candida 16%. Lifestyle data showed all sampled students were sexually active, 48% used contraceptives, 54% used antimicrobial agents, and 92% prefered wearing of trousers and shorts.

Conclusions

The present study indicates prevalence of vaginal infection among female students, which strongly correlates with student lifestyle. Education on lifestyle modifications will go a long way in reducing the prevalence of vaginitis.
