Spatial distribution of scorpions according to the socioeconomic conditions in Campina Grande,State of Paraíba, Brazil

Temporal trend and epidemiological profile of accidents involving venomous animals in Brazil, 2007-2019

OBJECTIVE

to analyze the temporal trend of accidents involving venomous animals in Brazil from 2007 to 2019.

METHODS

this was a cross-sectional study carried out with data from the Notifiable Health Conditions Information System (SINAN). Prais-Winsten linear regression was used for the temporal analysis. We calculated incidence rates according to sex and age group, relative risk and case fatality ratio.

RESULTS

during the study period there were 2,102,657 cases of accidents involving venomous animals. With the exception of snakebite, the remaining accidents showed a rising temporal trend in most regions of the country. Scorpion stings, snake bites and spider bites were responsible for 86% of accidents, mainly affecting male people of working age. Accidents involving snakes (0.4%) and bees (0.3%) had the highest case fatality ratios. Children were the main victims of accidents involving bees, caterpillars and "others".

CONCLUSION

accidents involving venomous animals showed a rising temporal trend for most conditions, as well as different epidemiological profiles.

Retrospective clinical and epidemiological analysis of scorpionism at a referral hospital for the treatment of accidents by venomous animals in Alagoas State, Northeast Brazil, 2007-2017

Scorpionism has a high incidence rate in Brazil. It is considered a serious public health problem mainly in tropical and subtropical regions around the world. The number of scorpion accidents have increased over the years and the highest frequencies have been reported mainly in the Brazilian Northeast region. Therefore, in this study we report a retrospective clinical and epidemiological analysis of scorpion stings from 2007 to 2017 in Alagoas State, Northeast Brazil, at a referral hospital for assistance and treatment of accidents by venomous animals. During the analyzed period, the referral hospital treated 27,988 cases, and an increase in the number of cases has taken place over the years. The highest frequency of scorpion stings was observed in females, and the age range most affected was from 20 to 29 years old. The most stung body site was the foot, followed by finger, toe or hand. Regarding the severity, most severe cases were reported in children up to 4 years old (69.4%) and 50% of the total cases treated with serotherapy corresponded to patients in this age range. Interestingly, it was also found that the occurrence of systemic manifestations and the severity of the cases were significantly associated with pediatric patients. In this way, this study highlights the scorpionism as an environmental public health problem in Alagoas State, Northeast Brazil, as well as the need to intensify the epidemiological surveillance and educational campaigns to prevent and control scorpion accidents throughout the year.

Clinical and epidemiological aspects of scorpionism in the interior of the state of Bahia, Brazil: retrospective epidemiological study

BACKGROUND

Scorpion accidents have gained great visibility around the world because of the high frequency and severity with which they occur, and have become a global medical-sanitary problem.

OBJECTIVE

The aim of this study was to describe the sociodemographic, clinical and epidemiological profile of scorpionism in the municipality of Jequié, Bahia, Brazil, from 2007 to 2015.

DESIGN AND SETTING

Retrospective epidemiological study in the municipality of Jequié, Bahia, Brazil.

METHODS

This study was based on data collected from the epidemiological investigation notification forms of the injury information system.

RESULTS

There was an increase in the coefficient of incidence of scorpion accidents in Jequié from 23.4/100,000 in 2007 to 413.6/100,000 in 2015. There were 3565 cases: 54.9% were female, 58.8% were aged 20-59 years, 63.5% had brown skin color and 48.6% had incomplete primary education. Most accidents occurred in urban areas (93.1%). Homes were the main place of occurrence (84.5%) and upper limbs were the commonest sting sites (53.0%). Regarding clinical aspects, 66.4% of the cases received hospital assistance within one hour after the bite, 84.1% presented mild severity, 97.1% had local manifestations and 10.2% had systemic symptoms. Serum therapy was administered in 17.3% of the cases, and 99.9% evolved to cure.

CONCLUSION

There was an increase in the incidence of scorpion accidents in the municipality, which demonstrates the need for investment in actions that reduce the morbidity and mortality caused by these accidents, such as educational campaigns and improvements in socioeconomic and health conditions.

Epidemiological study of scorpion stings in the Rio Grande do Norte State, Northeastern Brazil

This communication is a retrospective epidemiological study of the scorpion sting cases recorded from 2007 to 2014 in the Rio Grande do Norte State, Northeastern Brazil.
