[Hypothermia in elderly patients].

Hypothermia in older patients is a serious symptom, with high morbidity and mortality, and often an atypical presentation of an underlying problem. The most common causes are an infection and exposure to extreme cold ('accidental hypothermia'), but there are other, less common causes. These two cases show hypothermia as one of the symptoms in atypical presentations of underlying conditions. It is important to run diagnostics for infectious diseases and other underlying causes, and start antibiotics promptly. If there is no response to antibiotics and diagnostics do not reveal evidence of an infection, clinicians need to consider other causes of hypothermia.
