[Differences in differential diagnosis between acute mesenterial lymphadenitis and appendicitis in children].

The thermal streams intensity (THSI) from definite points of anterior abdominal wall in children with an acute mesenterial lymphadenitis (AML) and an acute appendicitis (AA) were determined. It was established, that in right inguinal region THSI in AA was in 4.06 times higher than in AML, in paraumbilical region--THSI was in 2.78 times, in the left subcostal region--in 1.76 times higher in AML than in AA. In the right subcostal region THSI was higher in an AA. Differential algorithm for AML and AA was determined. In children with an AML the circulating immune complexes level in the blood plasma was by 26.4% higher than such in children with an AA, presenting possible additional differential-diagnostical criterion.
