Scorpion envenomation in Brazil and its relationship with the social determinants of health: A population-based ecological study.

This study comprehensively analyzed cases of scorpion envenomation in Brazil, exploring the temporal trends and geographic patterns of such incidents between January 1, 2012, and December 31, 2022. Simultaneously, we assessed the correlation between scorpion envenomation and social determinants of health and social vulnerability. We conducted a population-based ecological study, gathering information on the number of scorpion envenomation cases in Brazil, as well as socioeconomic data and social vulnerability indicators across the 5,570 Brazilian municipalities. The season-trend model, based on the classical additive decomposition method, informed estimations of scorpion envenomation variations over time. The spatial correlation of scorpion envenomation with socioeconomic and vulnerability indicators was assessed using the Bivariate Moran's I. A total of 1,343,224 cases of scorpion envenomation were recorded in Brazil from Jan 2012 to Dec 2022. A single increasing time trend was observed for the entire country for this period (APC 8.94, P < 0.001). The seasonal analysis was significant for Brazil as a whole and all regions (p < 0.001), with peaks evident between October and November. The spatial distribution of cases was heterogeneous, with spatial clusters concentrated in the high-risk Southeast and Northeast regions. There was a high incidence of scorpion envenomation in municipalities facing social vulnerability, and, paradoxically, in those with better sanitation and waste collection. Our study revealed a heterogeneous geographical distribution of scorpion accidents in Brazil. Municipalities with higher social vulnerability exhibited a high incidence of scorpion envenomation.

Evaluation of Scorpion Stings in Children.

INTRODUCTION: Scorpion stings are a significant public health problem in many parts of the world. Children are at a higher risk of developing severe complications from scorpion envenoming, including cardiac, respiratory, and neurologic complications. In Turkey, members of the Buthidae family are the most common culprits in severe envenoming events. METHODS: This retrospective-descriptive study was conducted in Turkey. Children aged 0 to 18 y admitted to the emergency department of Kahta State Hospital between December 2017 and December 2020 were included in the study. Patient information was reviewed, and 78 patients with complete demographic, laboratory, and clinical data were included in the study. RESULTS: Out of the 78 patients, 24.4% were six years old or younger while the 75.6% were older than six years. Alpha blocker was given to 12.8% of the patients, and antivenom was given to 43.6% of the patients. Of the 78 patients, 71.8% were followed up in the emergency department, 21.8% were followed up in the inpatient unit, and 6.4% were followed up in the intensive care unit. Two patients (2.6%) died within 1 month. There was a significant difference regarding lactate dehydrogenase value according to the sting site (P=0.014). Lactate dehydrogenase values of patients stung on the head and neck and upper extremity were higher than those of patients bitten on lower extremities. CONCLUSIONS: Elevated levels of specific laboratory parameters, such as leukocytes, aspartate transaminase, and lactate dehydrogenase, are linked to worse outcomes. Additionally, stings on the head, neck, and upper extremities are more strongly associated with severity. These findings guide tailored treatment strategies for scorpion stings, with the potential for further refinement through broader studies across diverse regions and populations.

Scorpion sting envenomation outbreak in Mexico. Strategies for prevention and control.

In Mexico occurs 25% of all worldwide cases of scorpion sting envenomation (SSE). An outbreak of SSE was identified in Villa Unión, Sinaloa, Mexico. The objective of this study is to describe the outbreak, and prevention and control strategies implemented. The design was a cross-sectional study. Eligibility criteria included confirmed cases (n = 425) identified from the date the outbreak was recognized (from November 08, 2023 to July 10, 2023). The cases from Villa Unión (n = 231) were included for the analysis of epidemiological and clinical findings. The research followed the recommendations of the Initiative Reporting of studies Conducted Using Observational Routinely collected Data (RECORD). Of the total cases (n = 425), 398 (93.6%) were from the municipality of Mazatlán, and 231 (58%) were from Villa Unión. The incidence rate was 13.64 per 1000 persons. The average cases per week was 51.5(SD ± 12). The male-to-female ratio was 3:4, the average age was 30.7(SD ± 19) years. Most of cases occurred in the 25-44 age group. The sting occurred mostly inside houses (n = 200, 86.5%). The predominant symptoms were local pain (95.2%), and local paresthesia (75.8%). The Case fatality rate was 0%. Implementation of prevention and control strategies based on field epidemiological research and scientific evidence are necessary to reduce the incidence and prevent fatal complications.

Scorpion sting in Hafizabad, Pakistan: Facility based epidemiological study.

Scorpion envenomation is a widespread issue in tropical and subtropical countries. In the present study epidemiology of scorpion sting cases and potential treatment options in district Hafizabad, Pakistan are documented. Hafizabad city and the adjacent villages were selected for the data collection. Age, gender, time, site of scorpion sting on the body, scorpion sting symptoms, number of patients obtaining medical attention and the number of fatalities (if any) were noted. Data showed that scorpion envenomation often occurs in people between the ages of 16-47 years. There were more female victims (55%) and most of the scorpion sting incidences (55.49%) occurred between 07 PM and 02 AM Among body parts, both the hands (41.71%) and feet (48.57%) were more vulnerable to scorpion stings. In rural areas, the incidences of scorpion stings were higher (68.57%). The reported symptoms of scorpion stings include pain, hypertension, nausea and allergy. Out of all the victims, only 56.05% sought treatment from health care units as well as traditional medicine practitioners. However, others (43.94%) fully healed on their own without any treatment. People were using different types of plant-based materials and dead scorpions with mustard oil as a potent remedy against scorpion stings. Moreover, in the health care units there was no antivenom available and medical staff usually used common pain killers such as Xylocain and Lignocain for the treatment of scorpion sting.

First report of an accident caused by Jaguajir agamemnon (C.L. Koch, 1839) (Scorpiones, Buthidae) in Paraná state, Brazil.

We report the first pediatric case of a Jaguajir agamemnon scorpion sting. This case occurred in the state of Paraná and is the first record of this species in southern Brazil. The patient was admitted within 15 min, with pain, local edema, erythema, whole-body pruritus, and tongue paresthesia within the first two hours, which disappeared thereafter. The patient's condition was considered mild, with a positive outcome, and she recovered completely.

Moderate or severe scorpion sting: identification of risk factors.

OBJECTIVE: To characterize scorpion accidents at the Information and Toxicological Assistance Center (CIATox) in Campinas, to analyze risk factors related to the moderate and severe classification, and to determine the age group at greatest risk for this classification. METHOD: Cross-sectional and retrospective study, with patients assisted in person at CIATox, who had a scorpion accident, from January 2015 to December 2019. Descriptive and inferential analysis was conducted. For the age variable, a ROC curve was constructed to determine cutoff points in relation to the severity classification. Poisson regression models were adjusted considering severity classification as the dependent variable. RESULTS: A total of 754 cases with a mean age of 36.05 years, mostly female and non-occupational accidents that occurred in the urban area, was analyzed. The most frequent scorpion was the Tityus serrulatus. The risk factors found for greater severity were age group up to 22 years and previous care in other health services. CONCLUSION: The age range up to 22 years old should be used as a predictive factor of severity in the clinical evaluation of patients stung by scorpions to carry out adequate management of cases.

Scorpion envenomation in the neotropical savannah: Environmental predictors and years of lost life.

Scorpion stings envenomation (SSE) is a growing medical concern in Brazil, particularly in the state of Minas Gerais, which has recorded a significant number of incidents. This study aimed to investigate the potential predictors of scorpion sting incidence and evaluate the cost-effectiveness of interventions in Minas Gerais. Generalized Estimating Equations (GEE) models were constructed using socioeconomic and environmental variables as predictors and scorpion sting incidence as the response variable. The analysis revealed that mean annual temperature and major land use type were significant predictors of scorpion sting incidence, while precipitation and socioeconomic variables showed no relationship with incidence. The total number of cases and annual incidence of scorpion stings overlapped with regions experiencing higher forest conversion and agricultural land use, as well as higher temperatures. The estimated Disability-Adjusted Life Years (DALY) for scorpion sting incidents in Minas Gerais was substantial, indicating the need for effective prevention and treatment measures. The cost per DALY averted varied among municipalities, with some requiring minimal investment while others needing significant funding to address the scorpion risk. Mean annual temperature emerged as the main risk factor for scorpion stings, contributing to increased costs associated with antivenom treatment. These findings highlight the importance of considering environmental factors and implementing targeted interventions to mitigate scorpion sting incidents and reduce associated morbidity and mortality.

Mapping current and future risk of scorpion sting from a species with low medical concern, Mesobuthus phillipsii (Scorpiones: Buthidae) in Iran.

Scorpion stings are one of the most important health challenges and high priority research topic in public health. In this study, we aimed to model habitat suitability of the Mesobuthus phillipsii (Pocock 1889), a species with low medical concern, under current and future climatic conditions in Iran. We also identified vulnerable populations to scorpion stings in the country. Scorpion sting risk modeling was done using an ensemble approach by considering two species distribution modeling methods: MaxEnt and Random Forest methods. Distribution modeling was performed using the sdm R package. The results showed that due to climate change in 2070, the high-risk areas will increase from 20,839 to 79,212 km2. Habitats with a moderate risk of scorpion stings will also increase from 139,347 to 222,833 km2. Consequently, the number of villages in high-risk areas of scorpion stings will increase from 2,870 to 7,017, while this number will increase from 12,759 to 20,104 in the case of medium-risk villages. The results of this study can be used for scorpion stings management in Iran. This study can be used as an example for similar studies on scorpions with high medical emergency.

Mitochondrial swelling in cardiomyocytes: Insights from a murine model of Tityus serrulatus scorpion envenomation.

Immune system hyperactivation is involved with clinical severity and pathological alterations during scorpion envenomation. In a murine model, mice inoculated with a lethal dose of Tityus serrulatus scorpion venom presented mitochondrial swelling in cardiomyocytes, with other structures such as sarcomeres and intercalated disks preserved. Treatment with dexamethasone or knockout animals to the interleukin-1ß receptor do not undergo mitochondrial changes in cardiomyocytes during envenomation.

Scorpion Stings in Minas Gerais (Brazil): A Monocentric Retrospective Study Evaluating All Envenoming Cases of Local Scorpionism.

INTRODUCTION: We aim to provide better insights into the demographic, epidemiological, and seasonal characteristics of scorpion envenomation reported in the Rio Doce Valley, Brazil. METHODS: We conducted this monocentric retrospective descriptive study with data on Investigation Forms of Accidents by Venomous Animals, only envenoming cases of scorpion stings, between January 1, 2017 and December 31, 2020, belonging to the compulsory notification system of the Municipal Hospital of Governador Valadares. RESULTS: There were 3032 accidents, and the male-to-female ratio was 1.17:1 (male, 54%; females, 46%). Accidents occurred every month, but there was an increase in June, July, and October to January. In most cases, the time between the scorpion sting and medical care was between 1 and 3 h (n=1304; 43%). The most frequent clinical and systemic manifestations were pain at the bite site (94%) and vagal symptoms (7%). Cases were mild (n=2750, 91%), moderate (n=221, 7%), and severe (n=56, 2%). Children younger than 10 y constituted the most cases, 522 (17%). There was a significant difference between clinical severity and age (P<0.01). Ten patients developed acute pulmonary edema. Two 4-y-old children died. All severely envenomated patients as well as 74% and 2% of mild and moderately envenomated patients, respectively, received specific scorpion antivenoms. CONCLUSIONS: Scorpion envenomation is of greater severity in children aged <10 y. The clinical presentation includes mainly local pain associated with vagal symptoms. Accidents occur every month, but there was an increase in June, July, and October to January.

Indolealkylamines in the venom of the scorpion Thorellius intrepidus.

Scorpions are a group of arthropods that strike fear in many people due to their severe medical symptoms, even death, caused by their venomous stings. Even so, not all scorpion species contain harmful venoms against humans but still have valuable bioactive molecules, which could be used in developing new pharmaceutical leads for treating important diseases. This work conducted a comprehensive analysis of the venom from the scorpion Thorellius intrepidus. The venom of T. intrepidus was separated by size exclusion chromatography, and four main fractions were obtained. Fraction IV (FIV) contained small molecules representing over 90% of the total absorbance at 280 nm. Analysis of fraction FIV by RP-HPLC indicated the presence of three main molecules (FIV.1, FIV.2, and FIV.3) with similar UV absorbance spectra profiles. The molecular masses of FIV.1, FIV.2, and FIV.3 were determined, resulting in 175.99, 190.07, and 218.16 Da, respectively. Further confirmation through 1H-NMR and 13C-NMR analyses revealed that these molecules were serotonin, N-methylserotonin, and bufotenidine. These intriguing compounds are speculated to play a pivotal role in self-defense and increasing venom toxicity and could also offer promising biotechnological applications as small bioactive molecules.

Experimental approach to the dislodging effect and the mortality of a pesticide in the yellow scorpion Tityus serrulatus.

Accidents with scorpions are a problem in several regions of the world. In Brazil, the number of accidents is sometimes higher than 160k/year, and the responsible for most accidents and deaths is the yellow scorpion Tityus serrulatus. Unfortunately, there are few publications testing the effectiveness of most of the products for chemical control of scorpions. Using the pesticide Bifentol, we tested: I-the effect of the pesticide on the mortality of T. serrulatus, II-whether the scorpion avoids areas with pesticide and, III-whether it leaves the shelter if pesticide is applied. In the first experiment, we applied pesticide or water on the dorsal region of the scorpion or substrate according to treatment. For five days we noted whether the scorpion slide (dead) or clung to the substrate (alive) after turning the arena vertically to left and right. After five days, no pesticide-treated scorpions were alive while all water-treated scorpions were. In the second experiment, we placed two shelters, applied pesticide and/or water inside the shelter. We then released a scorpion on the opposite side. We scored latency to enter one of the shelters and the choice made by the scorpions. We did not find differences in latency or in the choice made. In the third experiment, we applied the pesticide or water to the shelter where the scorpion was being maintained, and, on the following day, we recorded whether the scorpion had left the shelter. None of the scorpions left the shelters and only one died. Thus, we obtained evidence that a pesticide can kill scorpions, but we did not find a dislodging effect.

Epidemiology of arthropods envenomation in Brazil: a public health issue.

Brazil is located between the Equator and Tropic of Capricorn, which allows diverse climates, reliefs, and habitats for arthropods, which sting represents a risk to human health and a public health issue. This manuscript updates the epidemiological data of cases of human envenoming by spiders, scorpions, and insects with medical relevance in Brazil from 2010 to 2021. Epidemiological data were taken using the Brazilian Notifiable Diseases Information System. Statistics of non-parametric data used the Kruskal-Wallis followed by the Nemenyi test. On average, more than 145,000 envenomation and 145 deaths are recorded annually, and more than 60% of deaths are caused by scorpion bites. When the number of deaths was pondered by the number of cases with each arthropod, bees kill the most. Most stings cause mild symptoms and affect men of working age. The incidence decreases during the colder months, which is better noticeable in regions with well-defined seasons. The distribution is distinct among the regions: Southeast, Northeast, and South have the highest rate of bites. The growing number of cases of envenomation reported annually is a serious public health concern, especially involving scorpions, and highlights the importance of studying arthropod venom and improving the therapies.

Bloqueo del nervio ciático poplíteo ecoguiado en urgencias en un paciente pediátrico con dolor severo producido por una picadura de escorpión / Ultrasound-guided sciatic popliteal block performed at the Emergency Department in a patient with a scorpion bite and severe pain

Presentamos el caso de un paciente pediátrico que acudió a urgencias con dolor severo en la extremidad inferior derecha causado por la picadura de un escorpión. Ante la ausencia de respuesta a los analgésicos administrados se optó por realizar un bloqueo poplíteo ecoguiado, lo que consiguió una analgesia completa y permitió el manejo ambulatorio del paciente, sin referir efectos adversos. Las familias de escorpiones presentes en nuestro país no suponen un riesgo vital para el ser humano, pero su picadura produce una reacción local con dolor autolimitado a unas 24-48h que puede ser severo. El manejo prioritario es realizar una correcta analgesia. Las técnicas anestésicas regionales son de utilidad para el control del dolor agudo y pueden representar una colaboración eficaz entre los servicios de anestesiología y urgencias.(AU)

We report the case of a paediatric patient who presented at the Emergency Department with severe pain in the right lower extremity caused by a scorpion sting. Analgesics were ineffective, so we decided to perform an ultrasound-guided popliteal block. This, which achieved complete analgesia and allowed the patient to be followed up in the outpatient department, with no adverse effects. The sting of the species of scorpion found in Spain is not dangerous to human life; however, it causes self-limiting localised pain that lasts for 24-48hours, and can be severe. The first-line treatment is effective analgesia. Regional anaesthesia techniques are useful in the control of acute pain, and are an example of effective collaboration between the Anaesthesiology and Emergency services.(AU)

Spatiotemporal bayesian modelling of scorpionism and its risk factors in the state of São Paulo, Brazil.

BACKGROUND: Scorpion stings in Brazil represent a major public health problem due to their incidence and their potential ability to lead to severe and often fatal clinical outcomes. A better understanding of scorpionism determinants is essential for a precise comprehension of accident dynamics and to guide public policy. Our study is the first to model the spatio-temporal variability of scorpionism across municipalities in São Paulo (SP) and to investigate its relationship with demographic, socioeconomic, environmental, and climatic variables. METHODOLOGY: This ecological study analyzed secondary data on scorpion envenomation in SP from 2008 to 2021, using the Integrated Nested Laplace Approximation (INLA) to perform Bayesian inference for detection of areas and periods with the most suitable conditions for scorpionism. PRINCIPAL FINDINGS: From the spring of 2008 to 2021, the relative risk (RR) increased eight times in SP, from 0.47 (95%CI 0.43-0.51) to 3.57 (95%CI 3.36-3.78), although there has been an apparent stabilization since 2019. The western, northern, and northwestern parts of SP showed higher risks; overall, there was a 13% decrease in scorpionism during winters. Among the covariates considered, an increase of one standard deviation in the Gini index, which captures income inequality, was associated with a 11% increase in scorpion envenomation. Maximum temperatures were also associated with scorpionism, with risks doubling for temperatures above 36°C. Relative humidity displayed a nonlinear association, with a 50% increase in risk for 30-32% humidity and reached a minimum of 0.63 RR for 75-76% humidity. CONCLUSIONS: Higher temperatures, lower humidity, and social inequalities were associated with a higher risk of scorpionism in SP municipalities. By capturing local and temporal relationships across space and time, authorities can design more effective strategies that adhere to local and temporal considerations.

Occurrence of scorpion sting and associated factors in a highly marginalized municipality in Guerrero, Mexico: A cross-sectional study.

BACKGROUND: Scorpion sting is a neglected public health problem, despite a global estimate of 1.2 million scorpion stings and some 3,250 deaths annually. METHODS: This cross-sectional study estimates the occurrence of scorpion stings and identifies associated factors in seven communities in the highly marginalized municipality of Chilapa, in the Mexican state of Guerrero. After informed consent, 1,144 households provided information on 4,985 residents. The questionnaire collated sociodemographic data, characteristics of the dwelling, efforts to avoid scorpion stings, and individual information of scorpion stings suffered in the last year. Cluster-adjusted (acl), bivariate and multivariate analysis relied on the Mantel-Haenszel procedure. RESULTS: The overall period prevalence of scorpion stings in the year prior to the study was 4.4% (218/4985), 5.4% in men (126/2320), and 3.5% in women (92/2665), p<0.01. The majority occurred at home 68.3% (149/218), followed by agricultural fields 26.6% (58/218), street 2.8% (6/218), and work 2.3% (5/218). Factors associated with scorpion sting were carrying firewood (OR 2.1; CI95%acl 1.40-3.09), keeping free-range hens around of the home (OR 1.9; CI95%acl 1.19-2.85), residing in a rural area (OR 1.7; CI95%acl 1.04-2.78), being male (OR 1.6; CI95%acl 1.18-2.28), and helping with housework (OR 1.6; CI95%acl 1.04-2.40). CONCLUSION: This study confirms scorpion bites are a public health problem in these marginalized communities in Guerrero State, with risk factors related to living conditions and the work process at home and in the fields. Almost all risk factors identified could be reduced with low-cost interventions implemented by the communities themselves.

Pioneering in vitro characterization of macrophage response induced by scorpion venoms from the Brazilian Amazon.

There are several scorpion species of medical relevance around the world. Some of them are well characterized by their toxins and clinical outcomes. Brazilian Amazon has a great amount of these arthropods that have an impact in the scorpionism events specifically in this region of Brazil. Recently, several studies pointed out the immune system activation during scorpion envenouming as an important facet of scorpionism, inducing a sepsis-like state that culminates in clinical severity and death. In this work, we characterized the macrophage response of three species of clinical relevance in Brazilian Amazon: Tityus silvestris, T. metuendus and T. obscurus and one specie with no toxic effects to humans, Brotheas amazonicus. All the four species analyzed were able to induce pro- and anti-inflammatory cytokine production in a J774.1 murine macrophage model. This activation was dependent on TLR2/TLR4/MyD88 activation and abolished by TLRs antagonists. These results suggest that the venoms of the four species analyzed were able to induce macrophage response in agreement to the well-established immune activation by T. serrulatus venom. Our findings provide new insights into the clinical repercussions of scorpionism of uncharacterized species and point to new biotechnological applications of these venoms and possible supportive therapies in scorpionism.

Medicinal plants from Mexico used in the treatment of scorpion sting.

Scorpion sting envenomation is a major public health in Mexico. Rural communities rarely have antivenoms in the health centers, therefore, the people commonly resort to using medicinal plants to treat the symptoms of envenoming caused by scorpion venom, but this knowledge has not yet been reported in detail. In this review, we carry out a review of the medicinal plants used in Mexico against scorpion stings. PubMed, Google, Science Direct, and the Digital Library of Mexican Traditional Medicine (DLMTM) were used to collect data. The results showed the use of at least 48 medicinal plants distributed in 26 families, where Fabaceae (14.6%), Lamiaceae (10.4%), and Asteraceae (10.4%) have the maximum representation. The application of leaves (32%) was preferred followed by roots (20%), stem (17.3%), flowers (16%), and bark (8%). In addition, the most common method of use to treat scorpion stings is decoction (32.5%). The oral and topical routes of administration have similar percentages of use. In vitro and in vivo studies of Aristolochia elegans, Bouvardia ternifolia, and Mimosa tenuiflora were found, which showed an antagonistic effect on the contraction of the ileum caused by the venom of C. limpidus, likewise, they increased the LD50 of said venom and even B. ternofila showed reduced albumin extravasation. The results of these studies demonstrate the promising use of medicinal plants for future pharmacological applications; nevertheless, validation, bioactive compound isolation and toxicity studies are necessary to support and improve therapeutics.

Clinical, epidemiological and faunistic characterization of scorpionism in Azilal, Central High Atlas (Morocco).

The province of Azilal is one of the most scorpion-infested areas in Morocco. The current study aims to investigate the clinical and epidemiological characteristics of scorpion envenomation in the Azilal province, as well as to contribute to the study of its scorpio-faunistic diversity. We examined clinical and epidemiological data from 5684 scorpion stings recorded between 2017 and 2021. Prospections on the ground were carried out in the study area. The species were identified using the taxonomic keys. Distribution maps of inventoried species have been created using SIG. 5684 scorpions stings were reported in the study area, with 18 cases of deaths. Most of the cases was reported in the summer especially at night (64%). A positive significant correlation was found between scorpion stings incidence and season (P < 0.005; r = 0.56). A positive correlation was found between scorpion stings incidence and mortality (r = 0.09). Pediatric mortality was higher compared to lethality in adults (P < 0.05). A positive correlation was found between the number of stung children (Age <15 years) and the number of patients presenting clinical signs of severe envenomation (Class III) (r = 0.40). The percentage of patients that use traditional remedies was significantly higher in the rural areas (P < 0.05). Most scorpion stings occurred in human habitat (54.5%) or in their neighbourhood (24.5%). Six species were identified in the study area. The findings of this study have highlighted the extent of scorpion envenomation and have elucidated certain characteristics of the scorpio-faunistic biodiversity in the Azilal province.
