Childhood burns in camping and outdoor cooking accidents: a focus for prevention.

We have seen increasing numbers of children who present with serious burns related to camping and outdoor cooking, prompting this 5-year review. Of 34 children (21 boys and 13 girls), with an average age of 5.2 years (4 months to 17 years) and average burn size of 15% (1% to 98%) cared for (4 as outpatients and 30 as inpatients), there was one fatality (3%). Mechanisms of injury included falling into free pits, throwing flammables into grills or pits, placing hands on hot objects in or near a fire, walking or falling into hot embers from an extinguished fire, spills from insect repellant candies, tent fires, burning of paper eating utensils, and cooking scalds. We have initiated a directed prevention program with the regional state park systems.

Uses and limitations of the balance technique.

Classical balance techniques are a powerful, sensitive, and usually accurate technique for assessing the nutritional or metabolic response to changes in nutritional intake or to metabolic or physiological perturbations. Balances are particularly sensitive for examining transient or short-term responses to nutritional or metabolic stimuli. A major factor responsible for the precision and sensitivity of this technique is the precise control of the activities and environment of an individual during a classical metabolic balance study (eg, the carefully defined dietary intake, degree of exercise, and environmental temperature to prevent sweating); these same factors may enhance the precision and sensitivity of other metabolic or nutritional investigations that may be carried out concurrently with a balance study. Finally, for nitrogen balance studies, the measurement of nitrogen (eg, by the Kjeldahl technique) can be very accurate and sensitive. Despite these advantages, there are important limitations and errors that are inherent in the balance technique. The errors tend to overestimate intake and underestimate output, thereby leading to erroneously positive balances. These errors include losses of food on cooking and eating utensils and dishware, losses of feces or urine on toilet paper or in collection containers, and losses through sweat, exfoliated skin, hair and nail growth, saliva, menses, blood sampling, toothbrushing, semen, and, for nitrogen, from flatus and respiration. Cumulative balance measurements are particularly likely to be falsely positive. The magnitude of unmeasured losses vary among healthy individuals, with the magnitude of the nitrogen intake (for nitrogen), in altered environmental conditions (eg, with sweating), and possibly in disease states. Balance studies are also expensive and time consuming.(ABSTRACT TRUNCATED AT 250 WORDS)
