Do we know how scabies outbreaks in residential and nursing care homes for the elderly should be managed? A systematic review of interventions using a novel approach to assess evidence quality.

Currently no national guidelines exist for the management of scabies outbreaks in residential or nursing care homes for the elderly in the United Kingdom. In this setting, diagnosis and treatment of scabies outbreaks is often delayed and optimal drug treatment, environmental control measures and even outcome measures are unclear. We undertook a systematic review to establish the efficacy of outbreak management interventions and determine evidence-based recommendations. Four electronic databases were searched for relevant studies, which were assessed using a quality assessment tool drawing on STROBE guidelines to describe the quality of observational data. Nineteen outbreak reports were identified, describing both drug treatment and environmental management measures. The quality of data was poor; none reported all outcome measures and only four described symptom relief measures. We were unable to make definitive evidence-based recommendations. We draw on the results to propose a framework for data collection in future observational studies of scabies outbreaks. While high-quality randomised controlled trials are needed to determine optimal drug treatment, evidence on environmental measures will need augmentation through other literature studies. The quality assessment tool designed is a useful resource for reporting of outcome measures including patient-reported measures in future outbreaks.

Donor site morbidity of an islanded inferior gluteal artery myocutaneous flap with vascularized fascia lata.

UNLABELLED: The perineal defect following extended abdominoperineal resection (APR) is commonly reconstructed with a pedicled vertical rectus abdominus muscle (VRAM) flap. To avoid unnecessary insult to the abdominal wall the authors have preferred an islanded inferior gluteal artery myocutaneous (IGAM) flap with vascularized fascia lata. The gluteal region is not without its own documented morbidity concerns which in this patient demographic is further complicated by nearby irradiated tissue and oncological surgery. This prospective review examines the donor site morbidity of patients following modified IGAM flaps. MATERIAL & METHODS: The records of all APR patients who had IGAM flap reconstruction performed by the senior author (August 2008-August 2012) were retrospectively reviewed for outcomes and complications, and then prospectively followed-up using a purpose-specific assessment tool. Outcome measures included (i) wound healing, (ii) posterior cutaneous nerve of the thigh (PCNT) and sciatic nerve function, (iii) gluteus maximus (GM) and tensor fascia lata (TFL) strength, and (iv) post-operative functional levels assessed using the 'Timed-Up-and-Go' (TUG) test and Oswestry Disability Index. RESULTS: Of the 35 patients who satisfied the inclusion criteria 32/35 (91%) patients completed the prescribed follow-up. The average age was 62 years (range 22-82) and mean follow-up period was 10.5 (range 3-32) months. All patients had rectal cancer and received neoadjuvant chemoradiotherapy, and all except two reconstructions were performed primarily. There were 3 cases (9%) of wound dehiscence none of which were attributed to wound infection or haematoma. Scar tenderness in 5 patients (16%) was the most common post-operative complaint. PCNT hypoesthesia affected 10/32 (31%) patients while there was no significant GM or TFL weakness. Mean TUG time was 9.6 (range 3.2-15) seconds, while mean ODI score was 6.6 (range 0-40). CONCLUSIONS: In spite of challenging circumstances the IGAM flap can provide appropriate wound coverage with surprisingly little donor site morbidity contrary to previous reports.

Acute hemorrhagic pancreatitis in the dog. IV. Treatment with vasopressin.

Acute hemorrhagic pancreatitis was experimentally induced in the dog by the closed-duodenal-loop technique. The disease process was modified and partially reversed by intravenous infusions of vasopressin, as indicated by some of our tests for pancreatitis as well as histologic examination of the pancreas.
