Abstract

PARDAL, Pedro Pereira de Oliveira et al. Epidemiological and clinical aspects of scorpion envenomation in the region of Santarém, Pará, Brazil. Rev. Soc. Bras. Med. Trop. [online]. 2003, vol.36, n.3, pp. 349-353. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822003000300006.

This is a descriptive and prospective study on epidemiological and clinical aspects of 72 scorpion accidents admitted to Santarém Municipal Hospital, state of Pará, Brazil, from February 2000 to February 2001. Only 8.3% brought the animal with them, identified as T. cambridgei. The majority of victims were male (83.3%). The mean age and the time of the medical help were respectively 33.6±18.3 years and 4.6±3.2 hours. The parts of the body most affected were the superior members (51.5%). Local symptoms occurred in 91.7% cases and systemic manifestations in 98.6% of the accidents. The local symptoms included: paresthesia in 79.2% cases, pain in 52.8% and edema in 26.4%. Among the systemic manifestations neurological disorders predominated in 97.2%, and the symptom of "electric shock" occurred in 88.9% patients. The most common neurological signs were: myoclonia (93%), dysmetria (86.1%), dysarthria (80.6%), and ataxia (70.8%). The accidents were classified as moderate in 76.4% without any serious cases. The specific anti-venom serum was not administered in 32.7% of the moderate cases, due to non-availability of the anti-venom serum at the time of attendance. The victims of scorpion envenomation notified at Santarém, present a different clinical and regional behavior from previous reports in Brazil and Amazonia regions. The predominantly neurological picture has not previously been described in the Brazilian literature.
