Eleven patients with high-tension electrical-arc-induced thermal burns due to railway overhead cables were treated at the Bratislava Burn Department during a relatively short period of 18 months. All the injuries occurred by the same mechanism, that is persons climbing on top of railway carriages and approaching the 25,000 V a.c. overhead cables. All the burns were the result of an electrical arc passing externally to the body, with subsequent ignition of the victim's clothes. ⋯ In spite of high-tension aetiology, no true electrical injuries appear to have occurred and no amputations were necessary. The pathophysiology and possible preventive measures are discussed. It must be stressed that arcing can be induced by an earthed object approaching, but not touching, a cable carrying a high voltage.

The charts of patients with burns covering more than 40 per cent of the body surface area (BSA) who were admitted to the Burn Unit of the Soroka Medical Center, Beersheva, Israel, between the years 1964 and 1988 were reviewed for mortality rate and causes of deaths. The factors affecting survival are reviewed and analysed.

Thermoplastic road markings are used at similar temperatures to tar and bitumen and spillage onto skin causes similar contact burns. Most of these occupational burn injuries can be avoided by adherence to the manufacturer's recommendations about the wearing of protective clothing. Management and foremen of contractors using these materials need to ensure that their workers comply with safe procedures and wear the specified protective clothing.

A 10-year retrospective study of burn injury associated with bonfires and barbecues was undertaken at a regional burns unit. Fifty-four patients were identified and their notes were reviewed. They represented 2.16 per cent of all burn admissions during this period.

With the introduction of silicone gel in 1981, the emphasis in the treatment of burn scar management has changed from pressure to the use of contact media. A range of 'contact media' has been introduced, allowing for therapy to be individualized to the patient and the scar. Over the last few years, the introduction of 'the adhesive technique' has allowed for earlier therapy with the aim of preventing or minimizing scar hypertrophy with better short- and long-term cosmetic results. The mode of action of 'contact media' is discussed, with a suggested hypothesis and further lines of investigation.
