Bites by coral snakes (Micrurus spp.) in Campinas, State of São Paulo, Southeastern Brazil

Coral snakes (Micrurus spp.) are the main representatives of the Elapidae in South America. However, bites by these snakes are uncommon. We retrospectively reviewed the data from 11 individuals bitten by coral snakes over a 20-year period; four were confirmed (snake brought for identification) and seven were highly suspected (neuromuscular manifestations) cases of elapid envenoming. The cases were classified as dry-bite (n = 1, caused by M. lemniscatus; did not receive antivenom), mild (n = 2, local manifestations with no acute myasthenic syndrome; M. frontalis and Micrurus spp.), moderate (n = 5, mild myasthenia) or severe (n = 3, important myasthenia; one of them caused by M. frontalis). The main clinical features upon admission were paresthesia (local, n = 9; generalized, n = 2), local pain (n = 8), palpebral ptosis (n = 8), weakness (n = 4) and inability to stand up (n = 3). No patient developed respiratory failure. Antivenom was used in ten cases, with mild early reactions occurring in three. An anticholinesterase drug was administered in the three severe cases, with a good response in two. No deaths were observed. Despite the high toxicity of coral snake venoms, the prognosis following envenoming is good. In serious bites by M. frontalis or M. lemniscatus, the venom of which acts postsynaptically, anticholinesterases may be useful as an ancillary measure if antivenom is unavailable, if there is a delay in obtaining a sufficient amount, or in those patients given the highest recommended doses of antivenom without improvement of the paralysis or with delayed recovery.

Envenomation by Micrurus coral snakes in the Brazilian Amazon region: report of two cases

Two cases of proven coral snake bites were reported in Belém, Pará State, Brazil. The first case was a severe one caused by Micrurus surinamensis. The patient required mechanical ventilation due to acute respiratory failure. The second case showed just mild signs of envenomation caused by Micrurus filiformis. Both patients received specific Micrurus antivenom and were discharged without further complications. Coral snake bites are scarcely reported in the Amazon region and there is a broad spectrum of clinical manifestations, varying from extremely mild to those which may rapidly lead to death if the patient is not treated as soon as possible.

Envenoming by coral snakes (Micrurus) in Argentina, during the period between 1979-2003

Envenomation by coral snakes (Micrurus sp.) is one of the most dangerous injuries in America and it is considered as a serious medical emergency, however bites by these snakes appear to be rare. We analyzed epidemiological data, clinical signs and antivenom use in Argentina during the period between 1979-2003. During this period of study 46 non-fatal Micrurus bites were reported. The majority of cases were men from 31 to 40 years old. Bites occurred primarily in spring and summer. Most cases were reported from the northeast and northwest provinces of the country. The bites were mostly located on hands or feet and occurred mostly during agricultural activities and so mainly involved farmers. Only four cases occurred as a result of handling snakes. The median time it took for antivenom to be administrated was 60 minutes after the bite, and the median number of vials applied was 2. Local pain was mentioned and edema was reported in 41% of patients. All patients recovered without sequelae. This study showed a low incidence of Micrurus bites and low severity of envenomation. However, although no deaths have been reported during the last 30 years, given the toxicity of the venom of Micrurus snakes, the risk of severe envenomation should be considered.

CORAL SNAKE ANTIVENOM PRODUCED IN CHICKENS (Gallus domesticus)

The production of anti-snake venom from large mammal's blood has been found to be low-yielding and arduous, consequently, antivenom immunoglobulins for treatment are achieved regularly as polyvalent serum. We have standardized an undemanding technique for making purified immunoglobulin IgY antivenom consisting of polyclonal antibodies against coral snake venom in the egg yolk of immunized hens. We have adapted a reported process of antibody purification from egg yolks, and achieved 90% antibody purity. The customized technique consisted of the removal of lipids from distilled water-diluted egg yolks by a freeze–thaw sequence. The specific immunoglobulins were present in the egg yolk for up to 180 days postimmunization. Therefore, by means of small venom quantities, a significant amount of immunoglobulins were found in an adequately purified state (The obtained material contained about 90% pure IgY). The antigen binding of the immunoglobulins was detected by a double immunodiffusion test. Titers of antibodies in the yolk were estimated with a serum protection assay (Median effective dose = ED50) (ED50= 477 mg/kg). Given that breeding hens is economically feasible, egg gathering is noninvasive and the purification of IgY antibodies is quick and easy, chicken immunization is an excellent alternative for the production of polyclonal antibodies. To the best of our knowledge, this is the first coral snake antivenom prepared in birds.

Coccidioidomicose: novo caso brasileiro

É descrito um caso de coccidioidomicose pulmonar oriundo da zona rural de Bertolínia, PI. A manifestação clínica principal consistiu em dor torácica e o diagnóstico teve por base o achado do agente3/4Coccidioides immitis3/4em cortes histológicos. Formas teciduais do microrganismo3/4esférulas imaturas e maduras3/4estavam presentes nas lesões observadas em fragmento pulmonar removido do paciente por biópsia a céu aberto. Este novo caso autóctone da doença, como os outros anteriormente descritos no Brasil, procedia do interior semi-árido da Região Nordeste. O ambiente quente e seco do sertão nordestino oferece, sem dúvida, condições propícias ao desenvolvimento de C. immitis, um habitante do solo. As pessoas e animais do local devem adquirir a infecção ao revolver a terra, ato que os expõe à poeira contendo os propágulos do fungo.

Avaliação do ciclo de vida do sistema de produção soja-girassol no cerrado Brasileiro.

RESUMO: O girassol é uma importante cultura na região de Parecis, no Cerrado brasileiro. Em 2014, a região respondeu pela produção de 232.700 t de grãos, 45% da produção nacional. A produção de girassol provém principalmente de um sistema que tem a soja como cultura principal. A associação entre soja e girassol pode reduzir impactos ambientais devido ao uso compartilhado de recursos. Este estudo desenvolveu uma Avaliação de Ciclo de Vida (ACV) ?do berço ao túmulo? do sistema de produção soja-girassol usado na região de Parecis e comparou seu perfil ambiental ao das monoculturas de soja e girassol. Impactos relacionados ao uso do solo (emissões da mudança de uso da terra e calagem) por cada cultura foram alocados em função do tempo de ocupação do solo. O sistema soja-girassol teve impactos ambientais menores em todas as categorias de impacto quando comparado à monocultura de soja e girassol, com o mesmo rendimento. Reduções importantes foram observadas em ?Mudança do Clima?, ?Acidificação Terrestre? e ?Formação de Material Particulado?. ABSTRACT: Sunflower is an important crop in Parecis region of the Brazilian Cerrado. In 2014 the region accounted for the production of 232,700 tons of sunflower grain, 45% of national production. Sunflower production comes mostly from a system that has soybean as the main crop. The association of soybean and sunflower can reduce environmental impacts due to shared use of resources. This study performed a ?cradle to gate? Life Cycle Assessment (LCA) of the soybean-sunflower production system used in Parecis region and compared its environmental profile to that of the monoculture of these two crops. Impacts related to the use of soil (land use change emissions and liming) by each crop were evaluated according to time of soil occupation criterion. Soybean-sunflower system had lower environmental impacts on every impact category comparing to soybean and sunflower monoculture with the same yield. Important reduction were observed on ?Climate change?, ?Terrestrial acidification? and ?Particulate matter formation? categories.
