“…Furthermore, nighttime stings were previously reported in Colombia originating from T. fuhrmanni , in South Africa from Parabuthus granulatus and in Iran from Hemiscorpius lepturus [16-18]. In Brazil, stings by T. bahiensis and T. serrulatus were reported as having occurred either at night or during the day [11,19]. …”

“…A variety of central nervous system (CNS) symptoms has been reported in human scorpionism by T. serrulatus , T. bahiensis and T. stigmurus , including somnolence, dizziness, contracture, tremors and seizures [10,11,20]. However, some neurological findings were observed only in envenomations attributed to T. obscurus in the western area and were not found in other regions of Pará state [6].…”

“…The specific treatment for scorpion envenomations in Brazil is based on the administration of species-specific antivenom, obtained from plasma of horses immunized with the venoms of T. serrulatus , which has been used effectively for the treatment of human scorpionism attributable to T. serrulatus , and other species such as T. stigmurus and T. bahiensis [3,10,11,20]. In addition, an in vivo and in vitro study showed that the antivenom of T. serrulatus can also be used successfully against T. obscurus [23].…”

“…In Brazil, local envenoming causes pain, erythema, and swelling. Systemic envenoming usually causes vomiting, sweating, hypersalivation, priapism, bradycardia or tachycardia, arterial hypotension or arterial hypertension, and cardiac failure, with little or no effect on the central nervous system [10,11]. There are few data describing the clinical and epidemiological features of envenomations due to T. obscurus in the Brazilian Amazon, in particular the difference in the occurrence of neurological signs or symptoms in some previously surveyed areas [7].…”

BackgroundScorpion 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 Tityus 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 by T. obscurus that occurred in western and eastern areas of the state.ResultsForty-eight patients with confirmed envenomation by T. obscurus were evaluated from January 2008 to July 2011. Most of them came from the eastern region, where male and female patients were present in similar numbers, while males predominated in the west. Median age groups were also similar in both areas. 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. Futhermore, neurological symptoms such as general paresthesia, ataxia, dysarthria, myoclonus, dysmetria, and electric shock-like sensations throughout the body were reported only by patients from the west.ConclusionThe present study shows that two regions of Para state differ in the clinical manifestations and severity of confirmed envenomation by T. obscurus which suggests a toxicity variation resulting from the diversity of T. obscurus venom in different areas of the Brazilian Amazon basin, and that T. serrulatus antivenom can be successfully used against T. obscurus.

“…O caso aqui relatado é considerado leve, sem manifestação de dor, mas com parestesia persistente no corpo. A ausência de dor intensa é um aspecto interessante deste caso, visto que esta é uma das principais manifestações de outros acidentes escorpiônicos já relatados 8,9 . Não foram observadas outras manifestações locais ou sistêmicas, como sudorese, vômitos, náuseas ou taquicardia.…”

RESUMOAcidentes escorpiônicos constituem um sério problema de saúde pública no Brasil. Rhopalurus agamemnon é um grande escorpião do bioma Cerrado, muito abundante em diversas localidades do Brasil Central. A espécie utiliza ambientes campestres e savânicos, sendo comum no interior de cupinzeiros. Entretanto, desaparece de locais onde o cerrado é removido. Os acidentes relatados apresentam sintomas de envenenamentos moderados, mas são baseados em identificações discutíveis. Aqui apresentamos o relato de um acidente seguramente causado por esta espécie. Concluímos que os poucos relatos disponíveis não permitem avaliar a gravidade dos acidentes e o eventual risco deste escorpião para a saúde pública. Palavras-chaves: Rhopalurus agamemnon. Envenenamento. Escorpiões. Cerrado. ABSTRACTAccidents caused by scorpions are a serious public health problem in Brazil. Rhopalurus agamemnon is a large scorpion found in the Cerrado (savanna) biome, and it is very abundant in many localities in central Brazil. The species inhabits open savanna environments, and is common inside termite mounds. However, it disappears from places where the native vegetation has been removed. The accidents reported present moderate symptoms of envenoming, but are based on questionable identifications. Here, we present a report on an accident that was certainly caused by Rhopalurus agamemnon. We conclude that the few reports available do not make it possible to evaluate the severity of such accidents and the possible risk to public health from this scorpion. Key-words: Rhopalurus agamemnon. Envenoming. Scorpions. Cerrado. Os escorpiões estão entre os primeiros animais a conquistarem o ambiente terrestre e apresentam ampla distribuição no mundo, sendo mais abundantes em ambientes áridos ou semiáridos 1,2 . Com o corpo dividido em três partes (prosoma, mesosoma e metasoma), possuem uma morfologia extremante conservada, bastante peculiar e facilmente identificável, especialmente pelo longo metasoma e pela presença de um par de palpos armados por pinças 1-3 . O metasoma é formado por cinco segmentos, sendo que a última peça do metasoma é a vesícula de peçonha, em cuja extremidade existe um aguilhão (ou ferrão), que permite ao animal injetar a peçonha 1-3 .Apesar dos escorpiões utilizarem a peçonha como mecanismo para imobilizar e matar suas presas (geralmente insetos e aranhas), muitos possuem peçonha potente, capaz de causar morte em humanos, especialmente crianças 4 . O rápido incremento de casos de envenenamento grave, no Brasil, demonstra a relevância que o escorpionismo possui para a saúde pública 4 . Cerca de oito mil casos de acidentes escorpiônicos são relatados, anualmente, no Brasil, onde todas as espécies de interesse médico pertencem à Família Buthidae 1 . O gênero Tytius engloba as espécies mais perigosas, com expressiva mortalidade de crianças nos acidentes graves relatados causados pela espécie T. serrulatus, talvez a mais perigosa da América do Sul 1 . No entanto, pouco se sabe sobre acidentes envolvendo espécies de outros gêneros de But...
