The author has analysed 339 patients with extensive burns admitted to a teaching hospital and found them to be most common in poor socioeconomic groups with low incomes, poor housing and illiteracy. Thermal injuries afflicted 89 per cent of the patients and were generally accidental and occurred in homes with floor-level cooking: chemical and electrical burns (the remaining 11 per cent) were uncommon. Kerosene pressure stove accidents were a common cause of thermal burns and occurred in 65 per cent of the patients. ⋯ Mishandling of kerosene pressure stoves was the commonest cause and occurred in 65.7 per cent of the patients and the next most common cause was wearing loose garments. Kerosene pressure stove accidents occurred commonly in the age group 16-35 years and were rare in other age groups. These burns were relatively more extensive, deep and carried a high mortality.

Three hundred and forty-two patients with 10-50 per cent body surface area burns were studied prospectively over the 5-year period from 1982 to 1986 for the effectiveness of topical 1 per cent silver sulphadiazine. Various parameters were studied including: (i) healing time of deep partial skin thickness burns, (ii) eschar separation time, (iii) conversion rate of deep dermal burns to full skin thickness burns, (iv) burn wound surface bacterial flora and their changing pattern over the years, (v) incidence of invasive sepsis and (vi) overall mortality. There was a remarkable decrease in the time taken for the healing of deep dermal burns, and the conversion rate of deep dermal burns to full skin thickness was significantly reduced. ⋯ There was a total change in the predominent surface micro-organisms from Staph. aureus, which was predominant in 1982, to pseudomonas species and klebsiella in 1986. Moreover, there was the emergence of a new variety of micro-organism within the last 2 years. The incidence of invasive infection and overall mortality was significantly reduced.
