“…has a pattern of coloured rings, children who are unaware of the danger can be compelled to handle it and then are bitten. 21 A Young people under 14 years old had the highest mortality as well as lethality in scorpion accidents, demonstrating that children and adolescents are a higher risk group, as reported by Nunes et al, 18 Soares et al, 19 Guerra et al, 25 and Bucaretchi et al 10 Because elderly persons have weakened immune systems, they are also a group at high risk for death and thereby require special attention. 18,19 Accidents with spiders had lower lethality (0.05%) compared to scorpion and snakes accidents.…”

“…This is probably because most cases of this type of poisoning occur in urban areas and in houses where these animals are found. 10,16,17 People between 20 and 59 years were also the main victims in cases of poisoning by scorpions and spiders. This might be associated with activities such as household chores (cleaning yards and doing laundry) and handling construction debris and materials.…”

“…5,6 The lethality of snakebite is 0.44%, 4 and there is an association between the severity of cases and age (children under 10 years and older adults experience the worst consequences). [7][8][9] The scorpions of medical interest in Brazil belong to the genus Tityus; three main species are responsible for serious, even fatal, poisonings in humans in the South, Southeast, Midwest and Northeast Brazil 6,10 : T. bahiensis (brazilian scorpion), T. serrulatus (yellow scorpion) and T. stigmurus.…”

“…In Brazil, medically important scorpions belong to Tityus genus; the major envenoming-related species are T. serrulatus and T. bahiensis in the Southeast, T. stigmurus in the Northeast, and T. obscurus (paraensis) in the North (Figure 1) (5) . Most stings involve mild envenoming, while more serious envenoming is caused by T. serrulatus (3) (4) (5) .…”

Scorpion stings are currently the leading cause of venom-related injury to humans in Brazil and are a signifi cant public health problem globally. Only scorpions of the Tityus genus are of medical importance in Brazil, and Tityus serrulatus is responsible for the most serious envenomations and deaths. The toxic effects of scorpion envenomation are due to a massive release of sympathetic and parasympathetic neurotransmitters; the severity is related to cardiac and hemodynamic changes, with cardiogenic shock and pulmonary edema contributing to the main causes of death. The pathophysiology of cardiac involvement has been discussed for decades and has been attributed to adrenergic discharge and a possible toxic effect of venom on the myocardium, while acute pulmonary edema may have a cardiogenic and/or non-cardiogenic origin. Currently, the clinical data point to catecholamine excess as the cause for reversible scorpion cardiomyopathy. These data include electrocardiographic changes, profi ling of cardiac enzymes and troponin I, echocardiographic data with global or regional left ventricle dysfunction, and myocardial perfusion alterations compatible with spasm in the coronary microcirculation. Furthermore, recent data on cardiac magnetic resonance imaging fi ndings, which are similar to those observed for stress-induced cardiomyopathy, have also been linked to catecholamine excess. The effi ciency of antivenom serum treatment is controversial in the literature. Our experience in Brazil is that the management of patients with systemic manifestations of scorpion stings is based on three approaches, all of which are extremely important. These include symptomatic treatment, antivenom serum, and cardiorespiratory support.

“…[1][2][3][4][5][6] Estes casos geralmente estão relacionados à sobreposição de uso do espaço entre o homem e animais, a atividade biológica dos animais, ao comportamento das espécies peçonhentas no ambiente e ao tipo de atividade desenvolvida pela vítima. 7 Todos os anos, no Brasil, ocorrem cerca de 100 mil acidentes por animais peçonhentos, resultando em 220 mortes e cerca de 1000 pacientes sofrem sequelas após uma picada de cobra.…”

Quanto às vítimas, prevaleceram indivíduos do sexo masculino (76,5%), na faixa etária entre 30 a 49 anos (41,2%), de raça parda (72,1%), com ensino fundamental (55,9%) envolvidos em atividades do campo como agricultura e pecuária (41,2%). Predominaram os acidentes de gravidade moderada (48,5%) e todos os casos graves foram provocados por serpentes. Na maioria dos agravos (75,0%), não foi registrada relação entre o acidente e a atividade ocupacional. As regiões corpóreas mais atingidas foram pé (39,7%), perna (20,6%) e mão (11,8%). As manifestações locais predominantes foram dor, edema e equimose. As manifestações sistêmicas de maior ocorrência foram hemorrágicas e vagais. Conclusão:Portanto, o período avaliado foi caracterizado pelo predomínio de acidentes com serpentes, no sexo masculino, em atividades do campo e de gravidade moderada. Assim, campanhas educativas e a adoção de medidas de prevenção são fundamentais para diminuir o registro desses agravos neste município. Background and Objectives:Accidents with poisonous animals are a public health problem in Brazil, especially in countryside cities. Updated regional information is important for the development of epidemiological surveillance activities. Through this research, we determined the epidemiological aspects of the cases registered in Nova Xavantina, State of Mato Grosso, Brazil, from January 2007 to May 2013. Methods: This is a cross-sectional and descriptive epidemiological study. Results: In this period, 68 accidents occurred, of which 44 were caused by snakes, 19 by scorpions, and four by spiders. Most accidents with snakes were caused by the genera Bothrops (79.5%), Crotalus (11.5%), and Micrurus (2.3%). As for the victims, there was a prevalence of males (76.5%), aged between 30 and 49 years (41.2%) of mixed race (72.1%), with basic education (55.9%) involved in field activities, such as agriculture and livestock (41.2%).There was a predominance of accidents of moderate severity (48.5%) and all serious cases were caused by snakes. In most injuries (75%), the relationship between the accidents and occupational activities was not recorded. The most affected body regions were the feet (39.7%), legs (20.6%), and hands (11.8%). The predominant local manifestations were pain, swelling, and bruising. The predominant systemic manifestations were hemorrhage, nausea and vomiting. Conclusion: The study period was characterized by the predominance of accidents involving snakes and male individuals in field activities and of moderate severity. Thus, educational campaigns and the adoption of preventive measures are essential to reduce the occurrence of these diseases in this city. http://dx.doi.org/10.17058/reci.v5i3.5724 ARTIGO ORIGINAL RESUMO ABSTRACT
