Severe Troponin I Elevation and Myocardial Dysfunction in a Child with Scorpion Sting.

 Scorpion sting is a common medical problem and major cause of mortality and morbidity in many countries. The symptoms of envenomation are more severe in the pediatric population. The clinical manifestations of scorpion envenomation appear by activation of sympathetic and parasympathetic nervous system. Envenomation can cause multiorgan dysfunction and death.  In this case report, we present a pediatric patient from Adana, Southeast Anatolia, with severe scorpion envenomation with which is an especially dangerous species for children. Severe systolic dysfunction was detected by echocardiography. Troponin I levels elevated significantly and rapidly responded to three doses of antivenom therapy.  Early echocardiographic examination is an important procedure for patients with scorpion envenomation. Troponin I is a significant parameter to monitor the degree of cardiac injury. Antivenom therapy is the only recommended specific therapy for children with severe scorpion envenomation due to . Abnormal echocardiography findings may require repeated doses of scorpion antivenom.
