Teaching the management of surgical emergencies through a short course to surgical residents in East/Central Africa delivers excellent educational outcomes.

Background: In Africa surgical trainees (residents) are often 'at the coalface' in managing surgical emergencies. A practical course on management of surgical emergencies was developed, as requested and guided by the learning needs of surgical trainees in East/Central Africa, to teach structured thinking processes in surgical emergencies; to thoroughly assess participants' knowledge, technical and non-technical skills; and to correlate assessment scores with participants' feedback on course quality.

Methods: Curriculum design was aimed at learners' needs, as guided by local trainers and previous teaching.

Salicylic acid sans aspirin in animals and man: persistence in fasting and biosynthesis from benzoic acid.

Salicylic acid (SA), which is central to defense mechanisms in plants and the principal metabolite of aspirin, occurs naturally in man with higher levels of SA and its urinary metabolite salicyluric acid (SU) in vegetarians overlapping with levels in patients on low-dose aspirin regimens. SA is widely distributed in animal blood. Fasting for major colorectal surgery did not cause disappearance of SA from plasma, even in patients following total proctocolectomy.

Peritoneal adhesions: pathogenesis, assessment and effects.

Background: As modem surgery has evolved, there has been an increase in iatrogenic peritoneal adhesions. Most surgeons manage adhesions and their related complications on a regular basis. Studies in recent years have improved the understanding of the pathogenesis and impact of adhesions, which are discussed.
