Unusual presentations of scorpion envenomation

Abstract

<jats:p> Scorpions are nocturnal arthropods that inject their venom through the victims’ skin by stingers. By the envenomation, clinical manifestations in a wide spectrum may occur, including pain at one side and death because of severe cardiopulmonary or neurological abnormalities. Sometimes the victim cannot describe the insect or does not remember even being stung after the event. We present two cases of scorpion envenomation with different and rare clinical situations with a short review of the literature. </jats:p>

Prazosin treatment in the management of scorpion envenomation

“…Lymphatics are the main way of transportation of the venom to reach the systemic circulation. 9,10 The severity of the envenomation is related to hemodynamic and cardio-respiratory alterations, with cardiac failure and cardiogenic pulmonary edema being the major causes of death. [3][4][5] Its pathophysiology, however, has not yet been completely established.…”

“…There are a few studies reporting that prazosin has been used successfully in cases with significant pulmonary and sympathetic nervous system symptoms due to scorpion sting envenomation. 1,2,[7][8][9] Prazosin may be an alternative and effective way of treatment in scorpion sting envenomations.…”

Posterior Reversible Encephalopathy Syndrome

“…Rarely or anecdotally reported associations with PRES include hypomagnesemia, hypercalcemia, hypercholesterolemia, acute pancreatitis, intravenous immunoglobulin, linezolid treatment, Guillain-Barré syndrome, Ephedra overdose, triple H therapy, tumor lysis syndrome, hydrogen peroxide, contrast media exposure, corticosteroid treatment, influenza A infection, lysergic acid amide, and scorpion poison. 13,19,[135][136][137][138][139][140][141][142][143][144][145][146][147][148][149][150][151]…”
