Clinical aspects of envenomation caused byTityus obscurus (Gervais, 1843) in two distinct regions of Pará state, Brazilian Amazon basin: a prospective case series
Background:Scorpion envenomations are a major public health problem in Brazil, whose most dangerous cases are attributable to the genus Tityus.This study was designed to compare the clinical and demographic features of envenomations by 77tyus obscurus in two areas of the state of Pará located in the...

Were compared demographic findings, local and systemic signs and symptoms of human envenomations caused byT. obscurus that occurred in western and eastern areas of the state.Results:Forty-eight patients with confirmed envenomation by T. obscurus were evaluated from January 2008 to July 2011.

Most scorpion stings took place during the day and occurred significantly more frequently on the upper limbs. The time between the sting and admission to the health center was less than three hours in both areas. Most eastern patients had local manifestations while in the west, systemic manifestations predominated. Local symptoms were similar in both areas, but systemic signs and symptoms were more common in the west. Symptoms frequently observed at the sting site were local and radiating pain, paresthesia, edema, erythema, sweating, piloerection and burning. The systemic manifestations were significantly higher in patients from the west.

Background:Scorpion envenomations are a major public health problem in Brazil, whose most dangerous cases are attributable to the genus Tityus.This study was designed to compare the clinical and demographic features of envenomations by 77tyus obscurus in two areas of the state of Pará located in the Amazon basin. Were compared demographic findings, local and systemic signs and symptoms of human envenomations caused byT. obscurus that occurred in western and eastern areas of the state.Results:Forty-eight patients with confirmed envenomation by T. obscurus were evaluated from January 2008 to July 2011.
