Platelet-activating factor (PAF) may be a major mediator of asthma and bronchial hyperreactivity through its many proinflammatory actions. Specific antagonism of PAF might offer an alternative anti-inflammatory treatment to inhaled corticosteroids. To test this, we have studied the effect of an orally active PAF antagonist, WEB 2086, on the inhaled steroid requirements of symptomatic atopic asthmatics in a double-blind randomized placebo-controlled parallel group study. The inhaled corticosteroid dose required for symptomatic control of asthma was established and further steroid reduction was attempted after treatment with WEB 2086 40 mg three times daily for 12 wk. Of 106 patients recruited, 68 entered the treatment phase and 65 completed 6 wk of treatment. The mean daily corticosteroid dose (SE) at study entry was 1,257 (75) micrograms which was reduced by 323 (66) micrograms during the run-in period without loss of symptomatic control. A further 416 (57) micrograms reduction in inhaled corticosteroid dosage was possible during the treatment phase but this was almost identical in the WEB 2086 and placebo-treated groups, amounting to 353 (92) and 481 (65) micrograms/day respectively (not significant [NS]). Rate of relapse following corticosteroid reduction was a continuous variable and relapse occurred at different times depending on the variable used to define it. Time to relapse measured by an increase in symptoms correlated with disease duration (r = 0.41, p < 0.01) and with the dose of inhaled corticosteroid at study entry (r = 0.36, p < 0.01) but no other measured variable predicted the time to relapse.(ABSTRACT TRUNCATED AT 250 WORDS)

SUMMARY The mechanism by which intragastric balloons induce weight loss is not known, although they may act simply by reducing the amount of food needed to induce satiety. The knowledge that a balloon is present may influence the patients' eating patterns and reduce caloric intake and weight. In order to test whether the balloon or the secondary psychological effect caused weight loss, a double blind balloon versus sham procedure was devised with both groups receiving identical outpatient dietary advice (800 kcallday). Twenty four obese women with body mass index greater than 30 kg/m2 from an obesity clinic were studied. Twelve had the balloon and 12 the sham procedure. The balloon was removed after three months and the patients were followed for a further three months. There was significantly greater weight loss in the balloon group, mean weight loss (SD) of 7.33 (6-12) kg compared with the sham group, mean weight loss (SD) of 3.33 (3.9) kg (p

The management of recurrent anterior gleno-humeral joint instability is challenging in the presence of bone loss. It is often seen in young athletic patients and dislocations related to epileptic seizures and may involve glenoid bone deficiency, humeral bone deficiency or combined bipolar lesions. It is critical to accurately identify and assess the amount and position of bone loss in order to select the most appropriate treatment and reduce the risk of recurrent instability after surgery. The current literature suggests that coracoid and iliac crest bone block transfers are reliable for treating glenoid defects. The treatment of humeral defects is more controversial, however, although good early results have been reported after arthroscopic Remplissage for small defects. Larger humeral defects may require complex reconstruction or partial resurfacing. There is currently very limited evidence to support treatment strategies when dealing with bipolar lesions. The aim of this review is to summarise the current evidence regarding the best imaging modalities and treatment strategies in managing this complex problem relating particularly to contact athletes and dislocations related to epileptic seizures.

Virtual fracture clinics (VFC) are advocated by new orthopaedic (British Orthopaedic Association) and National Health Service (NHS) guidelines in the United Kingdom. We discuss benefits and limitations, reviewing the literature, as well as recommendations on introducing a VFC service during the coronavirus pandemic and into the future. A narrative review identifying current literature on virtual fracture clinic outcomes when compared to traditional model fracture clinics in the UK. We identify nine relevant publications related to VFC. The Glasgow model, initiated in 2011, has become the benchmark. Clinical efficiency can be improved, reducing the number of emergency department (ED) referrals seen in VFC by 15–28% and face-to-face consultations by 65%. After review in the VFC, 33–60% of patients may be discharged. Some studies have shown no negative impact on the ED; the time to discharge was not increased. Patient satisfaction ranges from 91–97% using a VFC service, and there may be cost-saving benefits annually of £67,385 to £212,705. Non-attendance may be reduced by 75% and there are educational opportunities for trainees. However, evidence is limited; 28% of patients prefer face-to-face consultations and not all have access to internet or email (72%). We propose a pathway integrating the VFC model, whilst having senior orthopaedic decision makers available in the ED, during normal working hours, to cope with the pandemic. Beyond the pandemic, evidence suggests the Glasgow model is viable for day-to-day practice. Cite this article: EFORT Open Rev 2020;5:442-448. DOI: 10.1302/2058-5241.5.200041

Boerhaave syndrome is a spontaneous perforation of the oesophagus secondary to forceful emesis. Surgery has been advocated in delayed presentations of Boerhaave's syndrome with mediastinitis. The over-the-scope clip (OTSC) by OVESCO® (Tubingen, Germany) has been used in the endoscopic management of gastrointestinal bleeds, fistulae and anastamotic leaks. We describe the successful endoscopic use of the OTSC in a delayed presentation of Boerhaave syndrome with mediastinitis. A 69-year-old gentleman underwent a computerised tomography scan, which demonstrated a lower oesophageal perforation and mediastinitis 7 days after admission, having presented with forceful emesis and chest discomfort. During endoscopy the defect was visualized and successfully closed using the OTSC. This resulted in a favourable outcome and is a technique not previously described in the literature to manage this condition.
