    Abstract:
    INTRODUCTION: A clinical course ranging from mild local findings to life-threatening systemic findings may occur after scorpion stings. The purpose of this study was to identify priority markers indicating scorpion sting-related cardiac involvement. METHODS: Our study was performed between July 2014, and September 2015 in the Çukurova University medical faculty pediatric emergency department, in Adana, Turkey. Patients admitted with scorpion sting-related cardiac involvement and a control group consisting of patients with no scorpion sting-related cardiac involvement were included in the study. Troponin I at time of presentation and at 6 and 24 h, N-terminal prohormone of brain natriuretic peptide (NTproBNP), ejection fraction as determined by echocardiography at 24 h, and peak and end of T wave (Tp-e) and Tp-e/QTc ratios with echocardiography at 24 h were evaluated. RESULTS: A patient group consisting of 7 cases of scorpion envenomation-related myocarditis and a control group of 30 cases of scorpion intoxication without myocarditis findings were enrolled. Statistically significantly high glucose, white blood cell values, creatine kinase MB, troponin I, and NTproBNP values were identified in the scorpion sting-related myocarditis group (P<0.05). Ejection fractions determined by echocardiography at time of presentation were significantly lower in the patients with myocarditis compared with the control group (P<0.05). A statistically significant difference was identified between Tp-e/corrected QT interval (QTc) ratios investigated in DI and V2 derivations in patient and control group echocardiograms (P<0.05). CONCLUSIONS: We think that use can be made of NTproBNP in addition to echocardiography and troponin I in the early diagnosis of scorpion sting-related myocarditis and that Tp-e and Tp-e/QTc ratios identified via echocardiography can be used as early markers; however, further studies with larger numbers are needed to confirm this.
