The Science behind Topical Negative Pressure Therapy

Topical negative pressure therapy (TNP) is an established part of modern wound healing. With an increasing choice in TNP providers, understanding the differing modes of action, the biochemical and biophysical effects on the wound at a microscopic and macroscopic level, plus the role of the interface dressings, will aid the clinician in planning a clear goal of therapy. This article reviews the scientific evidence for TNP to date and explores each mechanism of action and the implications for wound healing and patient outcomes.     

Effects of X Chromosome Monosomy and Genomic Imprinting on Observational Markers of Social Anxiety in Prepubertal Girls with Turner Syndrome

Journal of Autism and Developmental Disorders - Previous studies have suggested that girls with Turner syndrome (TS) exhibit symptoms of social anxiety during interactions with others. However, few...     

Prevalence of unrepaired third- and fourth-degree tears among women taken to the operating room for repair of presumed obstetric fistula during two fistula camps in Kenya

Introduction and hypothesis

More than 2 million women on earth today are said to be suffering from obstetric fistula (OF), a communication between the vagina and either the urinary tract or rectum. Since unrepaired third- and fourth-degree perineal tears often manifest with symptoms identical to OF, we hypothesized that the global burden of OF is in part due to these unrepaired deep obstetric tears.

Methods

Four consultant gynecologists retrospectively reviewed the medical and operative records of all obstetric fistula cases that underwent surgical repair during the July and August, 2014, Kenyatta National Hospital and Embu Provincial Hospital Fistula Camps in Kenya.

Results

One hundred and eighty charts were reviewed. All 180 women had fecal incontinence (FI), urinary incontinence (UI), or both as their primary complaint. Sixty of the 180 (33 %) women had isolated FI as their presenting symptom, and at operation, 57 of these 60 (95 %) were found to have unrepaired third- and fourth-degree obstetric tears. Ninety-two of the 180 (51 %) women with OF symptoms ultimately had true OF confirmed at operation.

Conclusion

These findings suggest that many women with OF symptoms in Kenya may harbor unrepaired third- and fourth-degree tears. Additionally, women with isolated FI may be more likely to suffer from third- and fourth-degree tears than from true OF. Immediate postpartum diagnosis and repair of third- and fourth-degree perineal tears could significantly reduce the overall burden of women with symptoms of OF.

     

Reaping benefits from intellectual capital

The wealth and value of organizations are increasingly based on intellectual capital. Although acquiring talented individuals and investing in employee learning adds value to the organization, reaping the benefits of intellectual capital involves translating the wisdom of employees into reusable and sustained actions. This requires a culture that creates employee commitment, encourages learning, fosters sharing, and involves employees in decision making. An infrastructure to recognize and embed promising and best practices through social networks, evidence-based practice, customization of innovations, and use of information technology results in increased productivity, stronger financial performance, better patient outcomes, and greater employee and customer satisfaction.     

Terminal ileal mucosal mast cells in irritable bowel syndrome

Terminal ileal biopsies were prospectively obtained and stained specifically for mast cells in 20 patients with irritable bowel syndrome (IBS) and 15 controls. The number of terminal ileal mast cells per high powered field (MC/HPF) (mean ±SEM) was 23.3±3.1 for, IBS and 6.8±1.1 for controls (P=0.0001). The diarrhea IBS subgroup had the greatest number of MC/HPF. No correlation was found between terminal ileal mucosal mast cell counts (MMCC) and the number of Manning criteria present or the functional bowel disease score (r=0.06 andr=?0.31, respectively). We conclude that terminal ileal MMCC are significantly elevated in a majority of patients with IBS. The mast cell may be responsible for the altered visceral perception found in the gastrointestinal tract in patients with IBS. The poor correlation of the MMCC to the clinical features of IBS may be the result of the dynamic state of the mast cell.     

Society of Abdominal Radiology (SAR) and European Society of Urogenital Radiology (ESUR) joint consensus statement for MR imaging of placenta accreta spectrum disorders

This study was conducted in order to establish the joint Society of Abdominal Radiology (SAR) and European Society of Urogenital Radiology (ESUR) guidelines on placenta accreta spectrum (PAS) disorders and propose strategies to standardize image acquisition, interpretation, and reporting for this condition with MRI. The published evidence-based data and the opinion of experts were combined using the RAND–UCLA Appropriateness Method and formed the basis for these consensus guidelines. The responses of the experts to questions regarding the details of patient preparation, MRI protocol, image interpretation, and reporting were collected, analyzed, and classified as “recommended” versus “not recommended” (if at least 80% consensus among experts) or uncertain (if less than 80% consensus among experts). Consensus regarding image acquisition, interpretation, and reporting was determined using the RAND–UCLA Appropriateness Method. The use of a tailored MRI protocol and standardized report was recommended. A standardized imaging protocol and reporting system ensures recognition of the salient features of PAS disorders. These consensus recommendations should be used as a guide for the evaluation of PAS disorders with MRI. • MRI is a powerful adjunct to ultrasound and provides valuable information on the topography and depth of placental invasion. • Consensus statement proposed a common lexicon to allow for uniformity in MRI acquisition, interpretation, and reporting of PAS disorders. • Seven MRI features, namely intraplacental dark T2 bands, uterine/placental bulge, loss of low T2 retroplacental line, myometrial thinning/disruption, bladder wall interruption, focal exophytic placental mass, and abnormal vasculature of the placental bed, reached consensus and are categorized as “recommended” for diagnosing PAS disorders.
