RESUMO
An analysis was made of the 4-hourly temperature records of 137 malnourished Jamaican children, the consecutive admissions to a metabolic ward during a 3-year period. Mean rectal temperature of afebrile children during the first week in hospital was 0.52§C lower than it was in 19.7 percent of the children. It was related to low weight losses and height but not to serum or whole body potassium, serum sodium, or seasonal variation in ambient temperature. The incidence of of hypothermia in the survivors of this group of children was the same as it was in 42 children who died from severe malnutrition in the ward during the period 1960-1970. It is concluded that hypothermia is not an unfavourable prognostic sign in malnutritoned Jamaican children. Hypothermia was commoner in marasums than it was in kwashiorkor. In 11 afebrile chidren with kwashioker, rapid loss of oedema was associated with a fall in mean rectal temperature, suggesting that the insulating properties of oedema fluid may protect against hypothermia in kwashiorkor (AU)

A child with kernicterus and severe marasmus had marked thermoregulatory instability. An initial episode of hypothermia was attributed to deficient energy reserves, while experimental evidence suggested that subsequent intermittent fever was due to an unstable set-point of the hypothalmic thermoistat. Impaired vasomotor reactivity as a result of autonomic dysfunction may also have contributed to the unstable body temperature (AU)

The mean auricular temperature of 10 malnourished Jamaican infants was 0.84§C lower on admission to hospital than it was after recovery. Body temperature was influenced by ambient temperature in the malnourished state. During the rapid growth that accompanies recovery the mean auricular temperature was raised. Five malnourished children with hypothermia were given a standard high-calorie feed, and this caused the body temperature to return to normal levels within two hours in every case. These results suggested that reduced temperature in malnourished children may be an adaptation to conserve calories, and that severe hypothermia in malnutrition results from an acute shortage of energy reserves. Frequent feeding of malnourished chhildren is most important in their management. (Summary)
