Anatomical studies of the deltoid muscle were performed on 16 cadaver shoulders. The anatomy of the axillary nerve, the vascular pedicles, and the musculocutaneous perforators was assessed. These studies confirmed that part of the deltoid muscle can be used as a vascularised flap to cover defects of the shoulder while leaving some viable functioning muscle intact. ⋯ The flaps remained healed at one year follow-up. These soft tissue radionecrotic defects over the shoulder are an uncommon late complication of radiotherapy for breast cancer. Pedicled or free flaps are now recognised as the preferred methods of treatment.

Randomized Controlled Trial Clinical Trial
EMLA cream on the ears--is it effective? A prospective, randomised controlled trial of the efficacy of topical anaesthetic cream in reducing the pain of local anaesthetic infiltration for prominent ear correction.
A prospective, randomised, double blind trial was carried out to test whether or not the application of topical anaesthetic cream (EMLA cream) before infiltration of local anaesthetic would decrease the discomfort of correction of prominent ears under local anaesthetic. 23 patients were entered into the trial. They acted as their own controls, one ear having EMLA cream applied approximately 2 h prior to surgery, and the other Aqueous cream. ⋯ The results showed that, compared to the placebo cream, EMLA cream significantly decreased the pain felt both at the time of injection (p < 0.005) and during the surgery (p < 0.01). However, only 62% of patients asked felt that the inconvenience associated with the use of EMLA cream was worth the benefits that it conveyed.

In an experimental study on the epigastric venous system of rats, we examined three types of venous flaps with regard to their perfusion and long-term results: arterialised venous flaps, flow-through venous flaps and venous island flaps. We documented afferent and efferent blood flow with radiolabelled substances and blood distribution with infrared thermography. By measuring the surviving flap surfaces after 4 months, the relative success rate for each flap type was determined. ⋯ The venous island flaps had the worst distribution of intravenously injected 125J-Fibrinogen, and it was significantly worse in all types of venous flaps than in standard epigastric flaps; moreover, the clearance of intracutaneously injected 99mTc was the lowest in venous island flaps. The infrared thermographic study showed that the blood in the arterialised venous flaps dispersed faster and over a larger area than in flow-through venous and island flaps. Given these results, we conclude that arterialised venous flaps are the safest form of venous flaps, whereas venous island flaps carry a high risk of partial or total necrosis.

All paediatric scalds admitted in 1991 to the Welsh Centre for Burns and Plastic Surgery have been analysed retrospectively and the results compared with similar studies from this centre reported in 1956 and 1984. This data was compared with similar reports from 6 other world-wide centres. Despite a modest population increase in Wales, the number of admissions has increased almost 50% in 35 years. ⋯ Hot kettles are a common cause of scalds, accounting for up to 28% of scalds in all the series reviewed. The incidence of this injury has not decreased over the last 35 years. Recommendations are made about improved health and safety education for parents, the use of coiled kettle flexes, the temperature of stored water which should not exceed 60 degrees C, and the fitting of thermostatic mixer taps to new houses and institutions, in an effort to decrease the incidence of paediatric scalds.
