A patient is described who became poikilothermic following surgery for removal of a craniopharyngioma. Episodes of disturbed behaviour, neurological abnormalities, pancytopenia and deranged liver function could be correlated with episodes of more profound hypothermia on a background of a chronically lowered core temperature. The association of pancytopenia and neuropsychiatric disturbances with hypothermia is discussed with reference to reported cases of periodic spontaneous hypothermia.

A 14-year-old boy presented with a 1-week history of hypothermia and obtundation. His medical history included surgical resection of craniopharyngioma with postoperative visual impairment and panhypopituitarism. The patient's rectal temperature remained persistently lower than 35 degrees C during the first 3 days of hospitalization. His blood pressure was 90/56 mmHg on admission. The peripheral blood leukocyte count was 2.7 x 10(10)/L with 18% neutrophils, 19% band forms, 44% metamyelocytes, 3% myelocytes, and 16% lymphocytes. The C-reactive protein concentration was 133.9 mg/L. Two separate blood cultures both yielded Pseudomonas putida. The patient was treated with amikacin and ceftazidime along with aggressive fluid therapy. Replacement therapy directed at his hormonal deficiencies was initiated as soon as his hemodynamic status was stabilized. The patient responded well to therapy with a gradual rise in body temperature and improvement in general activity. A growth experiment carried out on the P. putida isolate showed that the bacteria grew more rapidly at 30 degrees C than at 37 degrees C. The clinical course of the patient, as well as the results of the laboratory study, suggest that hypothermia may predispose human infection with P. putida.

Hypothermia has been demonstrated to induce pancytopenia in animals, but whether this association exists in humans is unknown. The authors report the case of an 8-year-old girl in whom hypothermia (temperature 33 degrees C-35 degrees C) is the cause of pancytopenia. The patient developed thermoregulatory dysfunction subsequent to surgical resection of a craniopharyngioma. Her recurrent cytopenias could not be explained by any etiology except chronic hypothermia. The pancytopenia improved upon rewarming the patient to a temperature of 36 degrees C. This association between hypothermia and pancytopenia has rarely been reported in humans and may be underdiagnosed especially in cases of transient or milder presentations. The authors recommend careful hematologic monitoring of patients with thermoregulatory dysfunction.
