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.

The association between biomarker angiopoietin-like protein five and obstructive sleep apnea in patients undergoing bariatric surgery.

PURPOSE: Obstructive sleep apnea (OSA) is prevalent in the bariatric population. OSA should be recognized in patients undergoing bariatric surgery preoperatively to prevent peri- and post-operative complications. Lipid metabolism-related biomarkers are associated with OSA. Triglyceride metabolism is, among others, regulated by angiopoietin-like protein five (ANGPTL5). We aimed to evaluate the level of ANGPTL5 in patients with OSA of different severity levels before and after bariatric surgery. METHODS: We performed a single-center prospective cohort study including a consecutive series of patients who underwent bariatric surgery. We collected the clinical data, polysomnography (PSG) or polygraphy (PG) parameters, and plasma derived via venipuncture before and 6 to 12 months after surgery. Lipid profile, glucose levels, and ANGPTL5 levels were assessed. ANGPTL5 levels were measured using an enzyme-linked immunosorbent assay (ELISA). RESULTS: The study included 88 patients for analysis. The patients were divided into two subgroups: no or mild OSA (apnea-hypopnea index (AHI) < 15 events/hour, n = 57) and moderate-to-severe OSA (AHI ≥ 15 events/hour, n = 31). The ANGPTL5 level was higher in the moderate-to-severe OSA group (20.5 [15.6, 26.5] ng/mL) compared to the no or mild OSA group (16.3 [12.5, 19.4] ng/mL) (p = 0.008). A significant positive correlation was observed between ANGPTL5 and AHI (ρ = 0.256, p = 0.017), apnea index (AI) (ρ = 0.318, p = 0.003), and triglyceride levels (ρ = 0.240, p = 0.025). ANGPTL5 levels were reduced significantly after bariatric surgery in both moderate-to-severe OSA (15.6 [10.3, 18.7] ng/mL) and no or mild OSA (13.4 [9.2, 15.8] ng/mL) groups, though to a lower level in the group without or mild OSA. Post-surgery, the significant positive correlation between ANGPTL5 and AHI (ρ = 0.210, p = 0.047), AI (ρ = 0.230, p = 0.034), and triglyceride (ρ = 0.397, p < 0.001) remained. CONCLUSION: The data showed increased levels of ANGPTL5 in patients with moderate-to-severe OSA. Both AHI and ANGPTL5 levels decreased significantly after bariatric surgery. We also report an association between ANGPTL5 levels and OSA severity.

Perceived healthiness of food items and the traffic light front of pack nutrition labelling: choice-based conjoint analysis and cross-sectional survey.

BACKGROUND: Although traffic light labelling (TLL) is designed to aid the selection of healthier choices, consumers often have to make trade-offs between (un)desirable attributes. With the current emphasis of public health on sugar reduction, the present study aimed to investigate the relative influence of sugar on the perceived healthiness of products. METHODS: A choice-based conjoint analysis (CBC) survey was designed to assess the relative importance of the macronutrients commonly used in TLL, as well as the rescaled utilities of three attribute levels (red, amber and green), which involved 858 participants aged ≥18 years, who were recruited from the general population of Nottingham. An additional cross-sectional online survey was completed by another 901 participants to assess public knowledge about the intake recommendations underpinning the TLL. RESULTS: Usable data for CBC analysis showed that, when deciding upon the healthiness of items, sugar was significantly the most important macronutrient (mean 0.34, 95% confidence interval = 0.32-0.35) among the 641 participants. Red labelling was significantly more influential than green across macronutrients. In the substudy, 13.3% of participants correctly identify the maximum recommended intake of free sugars. Moreover, 42.8% of the total sample could not identify whether the sugar information on TLL refers to the total or free sugar content. CONCLUSIONS: Despite a lack of knowledge about the recommendations underpinning the TLL criteria, decisions made by participants concerning the healthfulness of food products were significantly influenced by sugar content. TLL appears to guide consumer beliefs in the absence of deep knowledge. The dominance of sugar in decision making is unsurprising in the current public health climate.

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.

Impact of obstructive sleep apnea on quality of life after laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: To examine the influence of obstructive sleep apnea (OSA) on the quality of life (QoL) in bariatric surgery. METHODS: All patients who underwent a laparoscopic Roux-and-Y gastric bypass (LRYGB), preoperative poly(somno)graphy and completed an Impact of Weight on QoL-Lite questionnaire before and after surgery were included. RESULTS: A total of 276 patients were included. OSA was diagnosed in 150 (53.3%) patients. All subscale scores improved 15 months post-surgery (p < 0.01). Total score improved from 51.2 (SD 19.1) to 89.7 (SD 13.9). Lower postoperative scores were seen in OSA patients on subscales Public Distress (90.4 SD 18.8 versus 95.7 SD 10.2; p = 0.003) and Work (92.9 SD 15 versus 96.1 SD 9.7; p = 0.031). All postoperative subscale scores were negatively correlated with OSA severity (p < 0.01). CONCLUSIONS: After LRYGB, QoL improved in both OSA and non-OSA patients. OSA patients, especially patients with severe OSA, have lower postoperative scores on subscales Public Distress and Work after LRYGB.

[Fibroepithelial tumours of the breast: not always a simple fibroadenoma]. / Fibro-epitheliale tumoren van de borst.

Fibroepithelial tumours are the most common type of solid breast tumours. They include the common fibroadenomas and the rare phyllodes tumours. Fibroadenomas usually present in younger patients and are smaller than phyllodes tumours. They are benign and do not require any treatment or follow-up. Further examination (usually ultrasound-guided thick-needle biopsy) is recommended if in doubt about the diagnosis. Phyllodes tumours can be divided into benign, borderline and malignant tumours and are primarily treated with surgery, breast-conserving surgery if possible. In this article, we present three cases and an overview of characteristics, diagnosis, and treatment of fibroepithelial breast tumours.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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 bypass.

Pseudoaneurysm after pertrochanteric femur fracture: a case report.

Vascular injury as a consequence of dislocated bone fragments after hip fractures is a rare complication. We report a case of a 78-year-old male who developed a pseudoaneurysm of the profunda femoris artery during rehabilitation after intramedullary fixation for a pertrochanteric hip fracture. As this procedure was minimally invasive, open reposition and fixation of the dislocated lesser trochanter were not performed. The pseudoaneurysm was diagnosed through duplex ultrasound and CT angiography and treated with thrombin injections and an endovascular Wallgraft covered stent. The imaging features are described in the article. Although a pseudoaneurysm is a rare complication after hip fractures, the development should be considered, in particular when symptoms such as pulsatile swelling or venous engorgement are presented.

Dietitians' perceptions of communicating with preadolescent, overweight children in the consultation setting: the potential for e-resources.

BACKGROUND: There are calls to enhance existing child weight management interventions and to develop new treatment approaches. The potential for interactive electronic resources (e-resources) to support child-dietitian communication has yet to be explored. Towards developing such a tool, the present study aimed to understand dietetic attitudes and approaches to communicating with preadolescent overweight children in individual consultations to support behaviour change. METHODS: A purposive sample of 18 dietitians, providing weight management advice to overweight 7-11-year-old children, took part in the study. Individual semi-structured telephone interviews were conducted. Data were transcribed and then analysed using inductive thematic analysis. Content analysis was used to interpret dietetic attitude towards e-resources. RESULTS: Six overarching themes were identified describing dietitians' views: the complexity of treating childhood obesity, the strategic balance of dietetic communication focus between child and parent, the child's capacity to communicate affecting their contribution, dietetic approaches to verbal child communication and the features of resources that can support them, as well as dietetic expectations for resources. Independent inter-rater agreement for the themes was 76.9% and 73.1%, respectively. The majority of dietitians (n = 13) supported the concept of introducing an interactive multimedia e-resource into child weight management consultations. CONCLUSIONS: Most dietitians sought to engage the preadolescent child in the consultation, using dietetic visual aids to complement verbal strategies and to serve as scaffolding for the conversation. There is scope for interactive e-resources to enhance communication, provided that they are flexibly tailored to meet the needs of the dietitian and the overweight child.
