This article suggests an alternative statistical model for studying the mortality of burned patients: discriminant analysis. This model was applied to our population of 532 patients among whom 71 died. ⋯ Discriminant analysis allowed us to demonstrate an impressive correlation between death, age and TBSA; inhalation injury by itself and sex, the two other significant factors in our study, seem to have a minor influence on the final outcome of the burned patients and their predictive value is virtually nil. The advantages of this statistical model are compared with logistic regression, the commonly chosen statistical method.

A prospective study of 394 burned children (in-patients) up to the age of 12 years old was carried out for the period from January 1984 to December 1986. They were categorized into three age groups, the infants and toddlers 0-2 years, early childhood 3-6 years and late childhood 7-12 years. In the first two groups scalding was the predominant cause of injury, while in late childhood there were many more flame burns. ⋯ The presence of parents was not a deterrent to the accident but ensured speedy transport to the hospital. In our review 3 per cent of patients sustained more than 50 per cent BSA burns, there were 12 deaths with a mortality rate of 3 per cent. An intense campaign to make parents aware of the risk factors and their avoidance is required to reduce the number of burn accidents.

This survey analyses data from nine Chinese burn units with respect to age, causes, severity of burn injury, and survival or death of patients admitted to hospital during the past 10 years (from January 1980 to December 1989). Of 12,606 burned patients treated, 3391 were children (26.9 per cent) and over half the children (52.3 per cent) were up to 4 years old. ⋯ The overall mortality rate was 1.24 per cent. The LD50 for the 12,112 patients less than 60 years old was a burned surface area exceeding 80 per cent of the total body surface area.

Burn victims have severely depressed cellular immunity and despite careful hygiene, antibiotics and early surgical therapy the infection rate remains high. The assessment of plasma neopterin levels can be considered as an indirect measurement of macrophage function, because activation of macrophages is accompanied by the release of D-erythro-neopterin. The influence of burn trauma on neopterin levels was investigated to determine whether neopterin estimations might have a prognostic or diagnostic value. ⋯ There were no differences between patients with TBSA less than 35 per cent or greater than 35 per cent, and between survivors and non-survivors. Burn injury caused a constant increase of plasma neopterin indicating an intact reaction by macrophages. It can be used as an additional parameter for the diagnosis of sepsis: high values being a sign of adequate reaction by macrophages, whereas low neopterin values in the presence of bacteraemia and clinical symptoms of sepsis show a deleterious impairment of immune functions.
