Non-excisional techniques for the treatment of intergluteal pilonidal sinus disease:a systematic review

Non-excisional techniques for pilonidal sinus disease (PSD) have gained popularity over the last years. The aim of this study was to review short and long-term outcomes for non-excisional techniques with special focus on the additive effect of treatment of the inner lining of the sinus cavity and the difference between primary and recurrent PSD. A systematic search was conducted in Embase, Medline, Web of Science Core Collection, Cochrane and Google Scholar databases for studies on non-excisional techniques for PSD including pit picking techniques with or without additional laser or phenol treatment, unroofing, endoscopic techniques and thrombin gelatin matrix application. Outcomes were recurrence rates, healing rates, complication rates, wound healing times and time taken to return to daily activities. In total, 31 studies comprising 8100 patients were included. Non-excisional techniques had overall healing rates ranging from 67 to 100%. Recurrence rates for pit picking, unroofing and gelatin matrix application varied from 0 to 16% depending on the follow-up time. Recurrence rates after additional laser, phenol and endoscopic techniques varied from 0 to 29%. Complication rates ranged from 0 to 16%, and the wound healing time was between three and forty-seven days. The return to daily activities varied from one to nine days. Non-excisional techniques are associated with fast recovery and low morbidity but recurrence rates are high. Techniques that attempt to additionally treat the inner lining of the sinus have worse recurrence rates than pit picking alone. Recurrence rates do not differ between primary and recurrent disease.</p

A systematic review of interactive multimedia interventions to promote children's communication with health professionals: implications for communicating with overweight children

Background: Interactive multimedia is an emerging technology that is being used to facilitate interactions between patients and health professionals. The purpose of this review was to identify and evaluate the impact of multimedia interventions (MIs), delivered in the context of paediatric healthcare, in order to inform the development of a MI to promote the communication of dietetic messages with overweight preadolescent children. Of particular interest were the effects of these MIs on child engagement and participation in treatment, and the subsequent effect on health-related treatment outcomes. Methods: An extensive search of 12 bibliographic databases was conducted in April 2012. Studies were included if: one or more child-participant was 7 to 11 years-of-age; a MI was used to improve health-related behaviour; child-participants were diagnosed with a health condition and were receiving treatment for that condition at the time of the study. Data describing study characteristics and intervention effects on communication, satisfaction, knowledge acquisition, changes in self-efficacy, healthcare utilisation, and health outcomes were extracted and summarised using qualitative and quantitative methods. Results: A total of 14 controlled trials, published between 1997 and 2006 met the selection criteria. Several MIs had the capacity to facilitate engagement between the child and a clinician, but only one sought to utilise the MI to improve communication between the child and health professional. In spite of concerns over the quality of some studies and small study populations, MIs were found useful in educating children about their health, and they demonstrated potential to improve children’s health- related self-efficacy, which could make them more able partners in face-to-face communications with health professionals. Conclusions: The findings of this review suggest that MIs have the capacity to support preadolescent child-clinician communication, but further research in this field is needed. Particular attention should be given to designing appropriate MIs that are clinically relevant

Proactive Assessment of Obesity Risk during Infancy (ProAsk): A qualitative study of parents' and professionals' perspectives on an mHealth intervention

Background: Prevention of childhood obesity is a public health priority. Interventions that establish healthy growth trajectories early in life promise lifelong benefits to health and wellbeing. Proactive Assessment of Obesity Risk during Infancy (ProAsk) is a novel mHealth intervention designed to enable health professionals to assess an infant’s risk of future overweight and motivate parental behaviour change to prevent childhood overweight and obesity. The aim of this study was to explore parents’ and health professionals’ experiences of the overweight risk communication and behaviour change aspects of this mHealth intervention. Methods: The study was conducted in four economically deprived localities in the UK. Parents (N=66) were recruited to the ProAsk feasibility study when their infant was 6-8 weeks old. Twenty two health visitors (HVs) used a hand-held tablet device to deliver ProAsk to parents when their infants were 3 months old. Parents (N=12) and HVs (N=15) were interviewed when infants in the study were 6 months old. Interview data were transcribed and analysed thematically using an inductive, interpretative approach. Results: Four key themes were identified across both parent and health visitor data: engaging and empowering with digital technology; unfamiliar technology presents challenges and opportunity; trust in the risk score; resistance to targeting. Most participants found the interactivity and visual presentation of information on ProAsk engaging. Health visitors who were unfamiliar with mobile technology drew support from parents who were more confident using tablet devices. There was evidence of resistance to targeting infants at greatest risk of future overweight and obesity, and both parents and health visitors drew on a number of reasons why a higher than average overweight risk score might not apply to a particular infant. Conclusions: An mHealth intervention actively engaged parents, enabling them to take ownership of the process of seeking strategies to reduce infant risk of overweight. However, cognitive and motivational biases that prevent effective overweight risk communication are barriers to targeting an intervention at those infants most at risk

Validity of a simple sleep monitor for diagnosing OSA in bariatric surgery patients

Background: One third of bariatric surgery patients have an apnea–hypopnea index (AHI)>15/hr, representing moderate and severe forms of obstructive sleep apnea (OSA). Treating these forms of OSA is recommended to reduce the risk of perioperative complications. The AHI derived from poly(somno)graphy [P(S)G] is the gold standard for OSA diagnosis. However, performing P(S)G in all patients scheduled for bariatric surgery is time consuming and expensive. An accurate and simple screening tool able to rule out moderate to severe OSA would reduce the number of patients needing mandatory P(S)Gs. Objectives: To assess the validity of a simple sleep monitor (Checkme Health Monitor) as a screening tool for OSA in bariatric surgery patients. Setting: Obesity Center Amsterdam, OLVG-West, Amsterdam, the Netherlands Methods: Patients scheduled for bariatric surgery were prospectively enrolled in this study. All patients underwent preoperative P(S)G and simultaneously used the Checkme to assess the oxygen desaturation index. The diagnostic performance of the Checkme for AHI ≥15/hr was assessed using receiver operating characteristic curve analysis. Results: A total of 50 patients were analyzed. Sensitivity and negative predictive value were 100% and 100%, respectively, specificity and positive predictive value were 69% and 64%, respectively, for the optimal cutoff value of Checkme-3% oxygen desaturation index ≥9/hr for P(S)G-AHI ≥15. The area under the curve value expressed by the receiver operating characteristic curve was.95. Conclusion: The Checkme is valid for exclusion of moderate and severe OSA in bariatric surgery patients. The Checkme enables bariatric clinics not to perform P(S)G in all patients scheduled for bariatric surgery

Do Complications Alter Postoperative Weight Loss 1 Year After Primary and Revisional Roux-en-Y Gastric Bypass?

Around 10 % of the bariatric surgery patients experience postoperative complications ( <30 days). It could be hypothesized that complications influence postoperative weight loss, which is one of the most important endpoints of bariatric surgery. Therefore, this study inventoried the effect of complications on postoperative weight loss. A consecutive database including patients who were operated from November 2007 onwards was retrospectively reviewed. All short-term complications were classified according to the Clavien-Dindo classification. Weight loss was assessed at 6 and 12 months postoperatively. A total of 1130 patients underwent either primary (n = 907, 80.3 %) or revisional (n = 233, 19.7 %) surgery till October 2013. Short-term complications occurred in 115 (10.2 %) patients, of whom 48 (41.7 %) had a severe (Clavien-Dindo ≥ 3) complication. One year post surgery, 184 patients (16.3 %) were lost to follow-up. Patients with a short-term complication had a higher percentage of excess weight loss (%EWL) at 6 months (58.6 (SD 16.6) versus 52.9 (SD 17.6), p = 0.003) and 1 year (71.9 (SD 22.3) versus 65.9 (SD 21.3), p = 0.017) of follow-up. Although a trend was seen toward higher BMI loss and total weight loss (TWL) after 6 months, no effect was seen 1 year postoperatively. In multivariable linear regression analysis, complications were not a significant predictor for 1-year %EWL. Although short-term complications alter 1-year %EWL, no effect was seen on BMI loss and TWL. In addition, complications were not a predictor in a multivariable linear regression model for 1-year %EWL. It can be concluded that short-term complications do not impair weight loss after Roux-en-Y gastric bypas
