Perfil epidemiológico dos acidentes causados por animais peçonhentos no município de Patrocínio, Minas Gerais: retrato de uma década / Epidemiological profile of accidents caused by venomous animals in the municipality of Patrocínio, Minas Gerais: portrait of a decade / Perfil epidemiológico de accidentes causados por animales venenosos en el municipio de Patrocínio, Minas Gerais: retrato de una década

Justificativa e objetivos: apesar dos avanços na área assistencial, os acidentes por animais peçonhentos ainda são um importante problema de saúde pública no Brasil. Entre os anos de 2015 e 2016, a região Sudeste apresentou o maior número de notificações, e Minas Gerais foi o estado com mais ocorrências. O objetivo deste estudo foi descrever as características epidemiológicas dos acidentes por animais peçonhentos notificados entre 2008 e 2017 no município de Patrocínio, Minas Gerais. Métodos: estudo descritivo retrospectivo realizado por meio da análise das informações das fichas de notificação do Sistema de Informação de Agravos de Notificação (SINAN) de vítimas de acidentes por animais peçonhentos ocorridos durante os anos de 2008 a 2017 em Patrocínio. Resultados: foram registrados 1.084 casos, a maioria ocasionada por escorpiões (47,23%), seguida por serpentes (17,07%), aranhas (15,31%) e abelhas (11,07%). Sobre as vítimas, constatou-se o predomínio de homens (63,10%) na faixa etária entre 20 a 39 anos (32,56%). A maior parte dos acidentes foi classificada como leve (89,11%) e a cura ocorreu em 98,80% dos casos; um evoluiu para óbito. Conclusão: embora os acidentes por animais peçonhentos não apresentem altas taxas de letalidade no município estudado, a incidência desse agravo de saúde tem aumentado nos últimos anos. Além disso, informações epidemiológicas atualizadas podem contribuir com ações de políticas públicas e informar a população local sobre os riscos iminentes.(AU)

Background and objectives: despite advances in health care, accidents involving venomous animals are still a major public health problem in Brazil. Between 2015 and 2016, the Southeast region had the highest number of notifications, and Minas Gerais was the state with more occurrences. The objective of this study was to describe the epidemiological characteristics of accidents by venomous animal notified between 2008 and 2017 in the municipality of Patrocínio, Minas Gerais. Methods: this is a retrospective descriptive study conducted by analyzing the information from reporting forms of the Notifiable Diseases Information System for victims of accidents with venomous animals occurred during the years 2008 to 2017 in Patrocínio. Results: in total, 1084 cases were recorded, mostly caused by scorpions (47.23%), followed by snakes (17.07%), spiders (15.31%) and bees (11.07%). There was a predominance of male victims (63.10%), aged between 20-39 years (32.56%). Most accidents were classified as mild (89.11%) and the cure occurred in 98.80% of cases; one evolved to death. Conclusion: although accidents with venomous animals do not have high mortality rates in the municipality studied, the incidence of this health problem has increased in recent years. In addition, this updated epidemiological information may contribute to public policy actions and inform the local population about imminent risks.(AU)

Snakebites in Rio Branco and surrounding region, Acre, Western Brazilian Amazon

Abstract INTRODUCTION Snakebites are considered a neglected tropical disease in many countries in Latin America, including Brazil. As few studies have assessed snakebites in the Amazon region and especially in the state of Acre, epidemiological studies are of great importance. The present study aimed to describe the epidemiological characteristics of snakebites in the Rio Branco region, observing their characteristics in rural and urban areas and their correlation with rainfall and river outflow. METHODS This retrospective, descriptive study analyzed epidemiological information obtained from snakebite notifications registered on the Information System for Notifiable Diseases that occurred from March, 2018 to February, 2019. The cases of snakebite were correlated with rainfall and flow. RESULTS A total of 165 cases of snakebite were registered in the period. Most cases were caused by Bothrops and affected mainly individuals of the male sex who were between 21 and 30 years old. Most of the snakebites occurred in Rio Branco (71.52%; 29 cases per 100,000 inhabitants). Of these, 60.2% occurred in the urban area and 39.8% in the rural area and the majority occurred during the rainy season. CONCLUSIONS Although studies have shown that a majority of cases occur in rural areas, in this study, urbanization of snakebites was observed. The Bothrops genus was responsible for the highest number of snakebites and, during the rainy season, bites occurred more frequently. Educational prevention campaigns, population advice, and first aid in case of snakebites for the population are thus suggested.

The deadliest snake according to ethnobiological perception of the population of the Alto Juruá region, western Brazilian Amazonia

Abstract INTRODUCTION: We examined the ethnobiological perception of the population of the Alto Juruá region about different snake species, in terms of their dangerousness and manifestations of envenomation. METHODS: We interviewed 100 villagers who were active in the forests. RESULTS: Lachesis muta was considered the most venomous snake, and Bothrops atrox appeared to be the most feared snake species. CONCLUSIONS: The high incidence, severity, and mortality of B. atrox bites and the severity and mortality of L. muta bites were the factors that contributed to these species being perceived as the most feared and venomous snakes.

Snakebites in the Municipality of Tarauacá, Acre, Western Brazilian Amazon / Acidentes ofídicos no Município de Tarauacá, Acre, Oeste da Amazônia brasileira

INTRODUCTION: Snakebites are a public health problem and are considered a common clinical emergency in several tropical countries, especially in rural and forested regions where these animals are more frequent. It is estimated that approximately 28,800 cases of snakebites per year occur in Brazil, with an average of 119 deaths, in which the north region has the highest rate of incidence. However, the accuracy of these data ends up being brought into question, since there are undoubtedly many cases of under-reporting and even cases that are not reported at all, due to logistical and geographical reasons or due to a lack of preparation as to the precise identification of the problem. OBJECTIVE: This study aimed to describe the epidemiological characteristics of the reported cases of snakebites victims in the municipality of Tarauacá (Acre), comparing the morbidity coefficient with other Amazonian regions, and to observe possible factors associated with the appearance of complications in these cases. METHODS: This is a retrospective descriptive study through the analysis of the clinical-epidemiological information found on the notification sheets of the Information System of Notification Diseases of victims of snakebites that occurred during the period between 2012 and 2016 in Tarauacá. RESULTS: We recorded 96 snakebite cases during the study period, with the majority (95.8%) classified as botropic, followed by laquetics (3.2%) and one by a non-venomous snake (1%). No deaths were recorded. Snakebites were more frequent in rural areas (87.5%), most being an occupational accident, and affected mainly adult male individuals in their lower limbs. Most cases occurred during the rainy season and had a positive correlation with rainfall. CONCLUSIONS: The morbidity coefficient registered in Tarauacá in 2016 (72.5 cases per 100,000 inhabitants) was higher than that recorded in the cities of Cruzeiro do Sul and Rio Branco and in the states of Acre and Amazonas. Although most patients receive antivenom within the first six hours, many victims do not receive appropriate hospital care until more than 24 hours after the envenoming, which is a factor associated with the appearance of complications.

INTRODUÇÃO: Os acidentes ofídicos constituem um problema de saúde pública, sendo considerada uma emergência clínica comum em vários países tropicais, principalmente em regiões de zona rural e florestadas, onde esses animais são mais frequentes. É estimado ocorrerem aproximadamente 28.800 casos anuais de acidentes ofídicos no Brasil, com uma média de 119 óbitos, no qual a região Norte apresenta a maior incidência. Todavia, a precisão desses dados acaba sendo questionada, pois devem ocorrer muitas subnotificações e mesmo não notificações por questões logísticas e geográficas ou decorrentes ao despreparo quanto à identificação precisa do agravo. OBJETIVO: Descrever características epidemiológicas dos casos notificados de vítimas de acidentes ofídicos no município de Tarauacá (Acre), comparando o coeficiente de morbidade com outras regiões amazônicas e observar possíveis fatores associados ao surgimento de complicações dos casos. MÉTODO: Trata-se de um estudo descritivo retrospectivo através da análise das informações clínico-epidemiológicas das fichas de notificação do Sistema de Informação de Agravos de Notificação de vítimas de acidentes ofídicos ocorridos durante o período de 2012 a 2016 em Tarauacá RESULTADOS: Foram registrados 96 casos durante o período de estudo, sendo a maioria (95,8%) classificada como botrópico, seguido de laquéticos (3,2%) e um por serpente não peçonhenta (1%). Nenhum óbito foi registrado. Os acidentes foram mais frequentes na área rural (87,5%), sendo um acidente ocupacional, acometendo principalmente indivíduos adultos do sexo masculino em seus membros inferiores. A maioria ocorreu durante a estação chuvosa e teve correlação positiva com a pluviosidade. CONCLUSÃO: O coeficiente de morbidade registrado em 2016 (72,5 casos por 100.000 habitantes) foi maior do que o registrado em Cruzeiro do Sul e Rio Branco e também para os estados do Acre e Amazonas. Apesar da maioria dos pacientes receber a soroterapia dentro das primeiras seis horas, muitos recebem o devido atendimento hospitalar após 24 horas decorrido o envenenamento, sendo um fator associado ao surgimento de complicações.

Popular names for bushmaster (Lachesis muta) and lancehead (Bothrops atrox) snakes in the Alto Juruá region: repercussions for clinical-epidemiological diagnosis and surveillance

Abstract INTRODUCTION: The popular names "surucucu" and "jararaca" have been used in literature for Lachesis muta and Bothrops atrox snakes, respectively. We present the popular names reported by patients who suffered snakebites in the Alto Juruá region. METHODS: Fifty-seven (76%) patients saw the snakes that caused the envenomations and were asked about their popular names and sizes. RESULTS: The snakes Bothrops atrox, referred to as "jararaca," were recognized as being mainly juveniles (80.7%) and "surucucu" as mainly adults (81.8%). CONCLUSIONS: The name "surucucu" is used in the Alto Juruá region for the snake B. atrox, mainly for adult specimens.

Non-venomous snakebites in the Western Brazilian Amazon

Abstract INTRODUCTION: In this study, we examined the clinical manifestations, laboratory evidence, and the circumstances of snakebites caused by non-venomous snakes, which were treated at the Regional Hospital of Juruá in Cruzeiro do Sul. METHODS: Data were collected through patient interviews, identification of the species that were taken to the hospital, and the clinical manifestations. RESULTS: Eight confirmed and four probable cases of non-venomous snakebites were recorded. CONCLUSIONS: The symptoms produced by the snakes Helicops angulatus and Philodryas viridissima, combined with their coloration can be confused with venomous snakes (Bothrops atrox and Bothrops bilineatus), thus resulting in incorrect bothropic snakebite diagnosis.

True or false coral snake: is it worth the risk? A Micrurus corallinus case report

Background Bites provoked by the genus Micrurus represent less than 1% of snakebite cases notified in Brazil, a tiny fraction compared with other genus such as Bothrops and Crotalus, which together represent almost 80% of accidents. In addition to their less aggressive behavior, habits and morphology of coral snakes are determinant factors for such low incidence of accidents. Although Micrurus bites are rare, victims must be rescued and hospitalized in a short period of time, because this type of envenoming may evolve to a progressive muscle weakness and acute respiratory failure. Case Presentation We report an accident caused by Micrurus corallinus involving a 28-year-old Caucasian sailor man bitten on the hand. The accident occurred in a recreational camp because people believed the snake was not venomous. The victim presented neurological symptoms 2 h after the accident and was taken to the hospital, where he received antielapidic serum 10 h after the bite. After the antivenom treatment, the patient presented clinical evolution without complications and was discharged 4 days later. Conclusions We reinforce that it is essential to have a health care structure suitable for the treatment of snakebite. Besides, the manipulation of these animals should only be carried out by a team of well-equipped and trained professionals, and even so with special attention.

Se describe el perfil epidemiológico del accidente ofídico en las tierras bajas de Guatemala a partir del análisis de 305 expedientes de casos atendidos en los hospitales regionales de Escuintla y San Benito, Petén, entre 2008 y 2013. De los 305 casos, 169 correspondieron al Hospital Regional de Escuintla y 136 al Hospital Regional de San Benito Petén. Los casos del Hospital Regional de Escuintla correspondieron a pacientes provenientes de los departamentos de Escuintla, Santa Rosa, Chimaltenango, Retalhuleu, Suchitepéquez, Sacatepéquez, Sololá y Guatemala. Los casos del Hospital Regional de San Benito Petén correspondieron a pacientes provenientes del área centro y norte de Petén, y algunos referidos del área sur. La edad media de la víctima fue 25.2 años. La enfermedad afectó más a hombres (61.3%) que a mujeres (38.7%). La mayoría de los afectados (28.3%) eran agricultores. Las especies de serpiente que se consignaron en los expedientes con mayor frecuencia fueron Bothrops asper (serpiente barba amarilla) en la región norte y Crotalus simus (serpiente cascabel) en la región sur. La mayoría de las mordeduras ocurrieron en los miembros inferiores. Los eventos de mordedura ocurrieron durante el día y durante la noche en proporciones similares. El tiempo medio que tarda la víctima en llegar al hospital fue de 5.6 horas. Se describen también otros aspectos epidemiológicos y se discuten las implicaciones ecológicas y sociales de los datos generado.

The epidemiological profile of snakebite envenomation in the lowlands of Guatemala is described. The data were generated from the analysis of 305 snakebite envenomation cases treated at Regional Hospitals in Escuintla and San Benito, Petén between years 2008 and 2013. The cases treated at the Regional Hospital of Escuintla occurred in the southern lowlands whereas the cases treated at the Regional Hospital of San Benito Petén occurred in the northern lowlands of Guatemala. The average age of the victim was 25.2 years. Envenomation frequencies were higher for men (61.3%) than for women (38.7%). Farmer was the most involved occupation (28.3%). Bothrops asper (the fer-de-lance snake) was recorded as the main causative of envenomation in the northern lowlands whereas Crotalus simus (the tropical rattlesnake) was the main causative species in the southern lowlands. Most snake bites occurred in the lower limbs of the victim. Envenomation occurred in similar proportions at day or at night. The elapsed time between the envenomation event and the arrival of the victim to the hospital was 5.6 hours. Other epidemiological aspects are also addressed and the ecological and social implications of the data are discussed.

Oftalmoplejía asociada a neurotoxicidad por veneno de serpiente: presentación de un caso y revisión de la literatura / Ophthalmoplegia associated with snake venom neurotoxicity: case report and literature review

Resumen El accidente ofídico es la lesión resultante de la mordedura de una serpiente, en el caso de ofidios venenosos se puede producir inoculación del veneno, constituyéndose además en ofidiotoxicosis. Esta entidad ha sido declarada por la Organización Mundial de la Salud como una enfermedad tropical olvidada. En el caso de Colombia constituye un problema aún vigente con una incidencia nacional de 9.7 casos por 100.000 habitantes, según datos reportados en el 2012. Las manifestaciones clínicas y la evolución de los pacientes se encuentran en relación directa con la composición del veneno de la serpiente, el cual es una especie específica. El propósito del presente artículo es describir, por medio de un caso clínico las características semiológicas y fisiopatológicas de un caso de ofidiotoxicosis con complicaciones neurológicas, haciendo una revisión de la literatura actual. Presentamos el caso de un paciente masculino, de 54 años de edad, que sufrió accidente ofídico grave, se discute con detalle las situaciones que pudieron haber contribuido al desenlace del paciente.

Summary The ophidian accident is the injury resulting from the bite of a snake, in the case of venomous snakes venom inoculation may occur, constituting itself in ophidiotoxicosis. This entity has been declared by the world health organization as a forgotten tropical disease. In the case of Colombia, this is still a problem, with a national incidence of 9.7 cases per 100,000 inhabitants, according to data reported in 2012. The clinical manifestations and evolution of the patients are directly related to the composition of the venom of the Snake which is specific species. The purpose of the present article is to describe, through a clinical case, the semiological and pathophysiological characteristics of a case of opiotoxicosis with neurological complications, making a review of the current literature. We present the case of a 54-year-old male patient who presented a severe ophidian accident, discussing in detail the situations that might have contributed to the outcome of the patient.

Acidentes com animais peçonhentos no Brasil por sexo e idade / Accidents with poisonous animals in Brazil by age and sex

INTRODUÇÃO: acidentes com animais peçonhentos são uma emergência clínica frequente em vários países tropicais, principalmente nos campos e áreas rurais, constituindo um problema de Saúde Pública, inclusive pediátricaOBJETIVO: analisar a morbidade, mortalidade e letalidade de acordo com a faixa etária e sexo nos casos de envenenamentos por serpentes, escorpiões e aranhas no BrasilMÉTODO: Os dados sobre envenenamentos por serpentes, escorpiões e aranhas ocorridos no período de 2009 a 2013 foram obtidos na base de dados online do Sistema de Informação de Agravos de Notificação - SINAN do Ministério da SaúdeRESULTADOS: foi registrada uma média de 28.812 casos por ano de acidentes ofídicos, 60.370,8 com escorpiões e 25.786,4 com aranhas. A maioria dos óbitos foi causada por serpentes (119 por ano) e também apresentou maior letalidade (0,41%), seguida por escorpiões (79,6 óbitos) com letalidade de 0,13% e, aranhas (13,2) com menor letalidade (0,05%). Em indivíduos do sexo masculino ocorreram a maioria dos casos de acidentes ofídicos, enquanto que nos acidentes com escorpiões e aranhas foi observado pouca diferença na frequência entre homens e mulheres. A faixa etária com maior número de registros de envenenamentos foi a de 20 a 39 anosCONCLUSÕES: ocorre um aumento progressivo de casos de envenenamentos a partir do primeiro ano de idade até a faixa etária compreendida entre 20 a 39 anos e após esta, começa uma diminuição. Crianças, adolescentes e adultos idosos, constituem grupos mais vulneráveis por apresentarem maiores índices de letalidade, especialmente nos acidentes ofídicos e escorpiônicos.

INTRODUCTION: accidents with poisonous animals are a common clinical emergency in several tropical countries, mainly in the fields and rural areas, constituting a public health problem, including pediatric OBJECTIVE: The objective is to analyze the morbidity, mortality and lethality according to age and sex in cases of poisoning by snakes, scorpions and spiders in Brazil METHODS: data on poisoning by snakes, scorpions and spiders that occurred from 2009 to 2013 were collected in the online database of the Information System on Diseases of Compulsory Declaration (SINAN) of the Ministry of Health RESULTS: were recorded 28.812 cases of snake bites per year, 60.370,8 with scorpions and 25.786,4 with spiders. Most deaths were caused by snakes (119 per year) and also showed higher lethality (0.41%), followed by scorpions (79.6 deaths) with a lethality of 0.13% and spiders (13.2) and the lowest mortality (0.05%). In males individuals were most cases of snake bites, whereas in accidents scorpions and spiders was observed little difference in frequency between men and women. The age group with the largest number of poisonings records was 20-39 years CONCLUSIONS: there is a progressive increase in cases of poisoning from the first year of age until the age range 20-39 years, and after this, begins a decrease in cases. Children, adolescents and elderly adults are most vulnerable because they have higher lethality rates, especially in the snake and scorpion accidents.

Epidemiología del ofidismo en Venezuela (1996-2004) / Epidemiology of ophidism in Venezuela (1996-2004)

Se analizaron los datos de accidentes por serpientes, registrados en las estadísticas de morbilidad de la Dirección de Epidemiología y Análisis Estratégico del Ministerio de Sanidad y Desarrollo Social. En Venezuela, entre los años 1996-2004, se registraron 53.792 mordeduras de serpientes (5.976 casos, en promedio, por año); con mayor incidencia en 2004 (7.486 incidentes). De todos los estados, Zulia reportó la mayor frecuencia (5.975 casos); mientras que la región Centro-Occidental, constituida por los estados Lara, Portuguesa, Falcón y Yaracuy, tuvo mayor morbilidad por mordeduras con 13.426. La mayor tasa por ofidismo, distribuida por estados, se registró en Cojedes, en el año 2001, con 228,72 casos por 100.000 habitantes. Cuando se determinó por regiones la mayor se ubicó, en 2004, en los Llanos, con 63,81 por 100.000 habitantes. La mediana de la tasa de incidencia para Venezuela en el periodo fue de 24,46 accidentes por 100.000 habitantes. La clasificación de las áreas de endemicidad por ofidismo, según los percentiles 25, 50, 75 y 90, ordenó al país en: (a) estados y regiones de muy alta endemicidad, (b) alta endemicidad, (c) mediana, (d) baja y (e) muy baja endemicidad. Las cifras indicaron que los accidentes causados por serpientes constituyen un problema de salud colectiva en Venezuela.

The data of accidents caused by snakebites in Venezuela, registered at the morbidity statistics of the Direction of Epidemiology and Strategic Analysis of the Ministry of Health and Social Development were analyzed. During the years of 1996-2004, 53,792 snakebites were registered in Venezuela (5,976 cases average per year), with a higher incidence during the year 2004 (7,486 incidents). Zulia reported the highest frequency of all the states (5,975 cases); meanwhile the Midwestern region, constituted by Lara, Portuguesa, Falcón and Yaracuy states, had a higher morbidity for snake bites. The highest incidence, distributed per states was registered in Cojedes, during the year 2001, with 228.72 cases per 100,000 inhabitants. When it was determined by regions, the highest incidence occurred during the year 2004 at los Llanos with 63.81 per 100,000 inhabitants. The median of the incidence rate for Venezuela during the period was of 21.46 accidents per 100,000 inhabitants. The classification of the endemic areas for ophidism, according to the percentiles 23, 50, 75 and 90, organized the country in: (a) states and regions of very high endemicity, (b) high endemicity, (c) middle, (d) low and (e) very low endemicity. These epidemiological data indicated that the accidents caused by snakes constitute a collective health problem in Venezuela.

Perfil epidemiológico de acidentes ofídicos do Estado do Amapá / Epidemiological profile of snake poisoning accidents in the State of Amapá

O presente trabalho apresenta o perfil epidemiológico dos acidentes ofídicos notificados junto à Secretaria do Estado de Saúde do Estado do Amapá. Para isso, foram analisadas 909 fichas durante o período de 2003 a 2006. A maior freqüência de picadas foi no ano de 2004 com registro de 255 casos, seguido pelo ano de 2006 com 246 casos. Os números mais expressivos de pacientes encontram-se nas faixas etárias compreendidas entre 20 e 34 anos (30 por cento). Os gêneros Bothrops e Crotalus foram responsáveis por 67,5 por cento e 0,7 por cento dos acidentes, respectivamente. Serpentes consideradas não peçonhentas causaram 0,2 por cento dos acidentes e em 31,2 por cento dos casos não foi possível a identificação da espécie. Indivíduos do sexo masculino (80,6 por cento) foram os mais atingidos. A maior incidência de picadas foi nos membros inferiores (68 por cento). Os acidentes ocorreram, em sua maioria, na área rural (62,7 por cento), em circunstâncias equilibradas de trabalho (60 por cento) e lazer (15,6 por cento). O tempo decorrido entre a picada e o atendimento ao paciente foi de 12 horas (29 por cento). Dos acidentes ofídicos, 263 foram classificados como leves, 193 graves e 187 moderados.

This study presents the epidemiological profile of snake poisoning accidents notified to the Health Department of the State of Amapá. For this, 909 records over the period from 2003 to 2006 were analyzed. The greatest frequency of bites was in the year 2004, with 255 cases recorded, followed by the year 2006 with 246 cases. The largest numbers of patients were in the age range between 20 and 34 years (30 percent). The genera Bothrops and Crotalus accounted for 67.5 percent and 0.7 percent of the accidents, respectively. Snakes that are considered non-venomous caused 0.2 percent of the accidents, and it was not possible to identify the species in 31.2 percent of the cases. Male individuals were more affected (80.6 percent). The highest incidence of bites was on the lower limbs (68 percent). The accidents mostly occurred in rural areas (62.7 percent), during balanced work circumstances (60 percent) or leisure activities (15.6 percent). The time elapsed from the bite to attending the patient was 12 hours (29 percent). Among the snake poisoning accidents, 263 were classified as mild, 187 as moderate and 193 as serious.
