Background:\ud Pyoderma gangrenosum (PG) is an uncommon dermatosis with a limited evidence base for treatment.\ud \ud Objective:\ud We sought to estimate the effectiveness of topical therapies in the treatment of patients with PG.\ud \ud Methods:\ud This was a retrospective cohort study of UK secondary care patients with a clinical diagnosis of PG that was suitable for topical treatment (recruited between July 2009 and June 2012). Participants received topical therapy after normal clinical practice (primarily topical corticosteroids [classes I-III] and tacrolimus 0.03% or 0.1%). The primary outcome was speed of healing at 6 weeks. Secondary outcomes included the following: proportion healed by 6 months; time to healing; global assessment; inflammation; pain; quality of life; treatment failure; and recurrence.\ud \ud Results:\ud Sixty-six patients (22-85 years of age) were enrolled. Clobetasol propionate 0.05% was the most commonly prescribed therapy. Overall, 28 of 66 (43.8%) ulcers healed by 6 months. The median time to healing was 145 days (95% confidence interval, 96 days to ∞). Initial ulcer size was a significant predictor of time to healing (hazard ratio, 0.94 [95% confidence interval, 0.88-1.00); P = .043). Four patients (15%) had a recurrence.\ud \ud Limitations:\ud Our study did not include a randomized comparator.\ud \ud Conclusion:\ud Topical therapy is potentially an effective first-line treatment for PG that avoids the possible side effects associated with systemic therapy. It remains unclear whether more severe disease will respond adequately to topical therapy alone.

Background: Surveys of aspiration prophylaxis in paediatric anaesthesia do not exist. Methods: A postal survey was sent out to all UK members of the Association of Paediatric Anaesthetists (APA) to assess current practice. We asked about minimum fasting times for liquids and solids/milk, their routine acid aspiration prophylaxis and perceived risk factors for emergency and elective surgery in children those less than 1 year old and those aged 1–14 years. We also asked if the APA member had more than 10 years experience in paediatric anaesthesia. Results: One hundred and two (55.1%) APA members replied out of a total of 185 questionnaires sent. Eighty-eight (88/102) were considered valid. Fasting in emergencies is approximately 4 h for solids/milk and 2 h for clear liquids. Fasting for elective surgery is between 5 and 6 h for solids/milk and 2 h for clear liquids. Pharmacological methods to reduce the risk of aspiration are not used. Mechanical methods vary from 40–50% for cricoid pressure and 20–30% for nasogastric aspiration if a tube is present. The presence of a hiatus hernia is perceived by over 80% as a risk factor, previous aspiration by over 60%, difficult intubation, cerebral palsy and sepsis by 20–30%. Conclusions: Perceived risk factors vary with ‘experience’: hiatus hernia, difficult intubation and cerebral palsy are less important whereas previous aspiration and renal failure appear to be more important for paediatric anaesthetists with less than 10 years in paediatric anaesthetic practice.

Summary The craniofacial abnormalities of popliteal pterygium syndrome present unique challenges to the pediatric anesthetist. Congenital fibrous bands between the maxilla and mandible limit mouth opening and the tongue may be fused to the palate. We describe the use of the Shikani Optical Stylet, a novel fiberoptic endoscope, in the airway management of a neonate with popliteal pterygium syndrome and syngnathia.
