[Thermographic semeiotics of food poisoning and its differential diagnosis].
A thermographic study has revealed zones of hyperthermia in the epigastrium and other abdominal regions in 91.4 per cent of the patients with food poisoning. The temperature gradient in the epigastrium depended on the degree of severity of the disease (in mild course--0.60 +/- 0.11 degrees C, in moderately severe and severe course--1.15 +/- 0.09 degrees C). In salmonellosis a zone of hyperthermia was also found in the right iliac region. Clinical recovery in most cases preceded temperature normalization on the abdomen. In patients with acute dysentery the hyperthermic zone was constantly revealed in the left iliac region, in acute appendicitis in the right iliac region, in acute cholecystitis in the right hypochondrium, in acute pancreatitis in the epigastrium or in the hypochondrium with a clearly defined upper border. Thermography contributed to the differential diagnosis of food poisoning and the above diseases.
