The role of social media in public health awareness during times of war in Sudan: snakebites and scorpion stings.

BACKGROUND: Snakebite envenomation (SBE) and scorpion sting envenomation (SSE) are significant neglected tropical diseases that primarily affect impoverished communities in rural areas of developing nations. A lack of understanding about snake and scorpion species and their distribution exacerbates the disabilities and fatalities caused by SBE and SSE. In Sudan, particularly in regions affected by ongoing conflicts where healthcare resources are scarce, social media platforms offer a cost-effective approach to addressing public health challenges. Our aim in this study is to highlight the benefits of using social media for data collection and health promotion in such environments. METHODS: We present a cost-effective communication and data collection strategy implemented at the Toxic Organisms Research Centre (TORC) of the University of Khartoum, focusing on a Facebook group, "Scorpions and Snakes of Sudan", as our primary social media platform. Additionally, we discuss the lessons learned and the initial impact of this strategy on enhancing population health literacy. RESULTS: The group community is composed of ~ 5000 members from 14 countries. During the period from January 2023 to January 2024, we received 417 enquiries about snakes and scorpions belonging to 11 families and composed of 55 species. In addition, 53 other enquiries covered a range of organisms and their tracks (e.g., spiders, skinks, chameleons, foxes, sun spiders, centipedes, lizards, moth larvae, and insect tracks). The first photographic evidence of Malpolon monspessulanus in Sudan was via the group activities. The rare species Telescopus gezirae, the Blue Nile cat snake, is also documented via the group member's queries. Recognizing the evolving nature of social media use in public health, we also address the current limitations and evidence gaps that need to be addressed to effectively translate best practices into policy. CONCLUSION: In conclusion, utilizing Facebook as an institutional platform to share scientific information in simple Arabic language underscores the proactive roles that citizens, scientists, and public health stakeholders can play in leveraging social media for eHealth, eAwareness, and public health initiatives. This approach highlights the potential for collaborative efforts, particularly during crises, to maximize the benefits of social media in advancing public health.

Scorpion-Induced Acute Coronary Syndrome: A Stinging Complication.

The Tityus trinitatis, a black scorpion species endemic to the fauna of Trinidad, has been implicated in envenomation with devastating clinical sequelae such as acute pancreatitis and major adverse cardiovascular events. We present the first in-Caribbean case of a 59-year-old Caribbean South Asian male with human immunodeficiency virus who presented with a non-ST-segment-elevation acute coronary syndrome after being stung, which was managed with comprehensive, guideline-directed medical therapy. The clinician should be cognizant of scorpion-induced acute coronary syndrome (ACS) as a potential sequela of envenomation and its clinical management.

Efficacy of Ropivacaine for Sub-Arachnoid Block in Patients with Recent History of Scorpion Sting: A case series.

Failure of sub-arachnoid block (SAB), due to resistance to bupivacaine after a recent scorpion sting can lead to multiple block attempts and subsequent conversion to general anaesthesia. We report this case series of 10 patients with successful SAB with newly launched 0.75% hyperbaric ropivacaine, in patients with recent scorpion sting. Thus, intrathecal hyperbaric ropivacaine may be considered as the local anaesthetic agent of choice in patients with scorpion sting to prevent failure of SAB.

Clinical outcomes in a murine model after envenoming by the Amazonian scorpions Tityus strandi and Tityus dinizi.

The Brazilian Amazon is home to a rich fauna of scorpion species of medical importance, some of them still poorly characterized regarding their biological actions and range of clinical symptoms after envenoming. The Amazonian scorpion species Tityus strandi and Tityus dinizi constitute some of the scorpions in this group, with few studies in the literature regarding their systemic repercussions. In the present study, we characterized the clinical, inflammatory, and histopathological manifestations of T. strandi and T. dinizi envenoming in a murine model using Balb/c mice. The results show a robust clinical response based on clinical score, hyperglycemia, leukocytosis, increased cytokines, and histopathological changes in the kidneys and lungs. Tityus strandi envenomed mice presented more prominent clinical manifestations when compared to Tityus dinizi, pointing to the relevance of this species in the medical scenario, with both species inducing hyperglycemia, leukocytosis, increased cytokine production in the peritoneal lavage, increased inflammatory infiltrate in the lungs, and acute tubular necrosis after T. strandi envenoming. The results presented in this research can help to understand the systemic manifestations of scorpion accidents in humans caused by the target species of the study and point out therapeutic strategies in cases of scorpionism in remote regions of the Amazon.

Development and Efficacy of the Antivenom Specific to Severe Envenomations in Morocco and North Africa: Advancements in Scorpion Envenomation Management.

Scorpion envenomation poses a global public health issue, with an estimated 1,500,000 cases worldwide annually resulting in 2600 deaths. North Africa, particularly Morocco, experiences severe envenomations, mainly attributed to Androctonus mauretanicus and Buthus occitanus in Morocco, and Buthus occitanus and Androctonus australis hector in Algeria and Tunisia, with case numbers often underestimated. Current treatment relies mainly on symptomatic approaches, except in Morocco, where management is limited to symptomatic treatment due to controversies regarding specific treatment. In Morocco, between 30,000 and 50,000 scorpion envenomation cases are reported annually, leading to hundreds of deaths, mainly among children. Controversies among clinicians persist regarding the appropriate course of action, often limiting treatments to symptomatic measures. The absence of a specific antivenom for the venoms of the most lethal scorpions further exacerbates the situation. This study aims to address this gap by developing a monovalent antivenom against the endemic and most dangerous scorpion, Androctonus mauretanicus. The antivenom was produced by immunizing albino rabbits with a mixture of Androctonus mauretanicus venom collected from high-risk areas in Morocco. Immunizations were performed by subcutaneous injections at multiple sites near the lymphatic system, following an immunization schedule. Production control of neutralizing antibody titers was conducted through immunodiffusion. Once a sufficient antibody titer was achieved, blood collection was performed, and the recovered plasma underwent affinity chromatography. The efficacy of purified IgG was evaluated by determining the ED50 in mice, complemented by histological and immunohistochemical studies on its ability to neutralize venom-induced tissue alterations and the neutralization of toxins bound to receptors in the studied organs. The monovalent antivenom demonstrated specificity against Androctonus mauretanicus venom and effective cross-protection against the venom of the scorpions Buthus occitanus and Androctonus australis hector, highly implicated in lethal envenomations in the Maghreb. This study shows that the developed monovalent antivenom exhibits notable efficacy against local scorpions and a surprising ability to neutralize the most lethal envenomations in North Africa. These results pave the way for a new, more specific, and promising therapeutic approach to countering severe scorpion envenomations, especially in Morocco, where specific treatment is lacking.

Does Covid-19 influence the dynamics of envenomation by animals in a country strongly affected by both conditions? Epidemiological data from Brazil.

The impact of Covid-19 on envenomations by venomous animals in countries heavily affected by both conditions has not been quantified yet. Brazil shows high incidence of envenomations by scorpions, spiders and snakes and was heavily affected by waves of Covid-19. To determine how the pandemic impacted the epidemiology of envenomations by those three groups of venomous animals, we used online databases from two surveillance sources on number of cases and mortality. During the years before and during the pandemic, scorpion stings typically occurred in adults of both sexes in urban zones in the Southeast and Northeast regions. Spider bites occurred mainly in the South region, in adults of both sexes in urban zone. Snakebites affected mainly rural adult men in the Amazon. Between 2007 and 2021, overall incidence of cases by scorpions, spiders and snakes decreased after the beginning of the pandemic, snakebites did not show changes after the pandemic started in Brazil, but cases by scorpions and spiders decreased. No changes in the incidence of deaths were observed. On national level, Covid-19 affected some demographic, clinical and epidemiological aspects in cases by scorpions, spiders and snakes.

Use of point-of-care ultrasound to assess the severity of scorpion stings in hospitalized patients.

INTRODUCTION: Scorpionism is a public health problem, especially in tropical regions. In Brazil, the prevalence of envenomation by scorpions is high, and the average national lethality is around 0.16 percent. The Tityus serrulatus scorpion is the primary species of medical importance. However, objective tools to predict and define the severity of these envenomations are lacking. MATERIALS AND METHODS: This was an observational study conducted among patients aged 0-19 years with scorpionism. Patients were admitted to a reference hospital between December 2020 and May 2022. Point-of-care ultrasound was performed within 24 hours of the scorpion sting. RESULTS: Forty-nine patients were included, with a median age of 3.6 (interquartile range 2.3-5.3) years and a predominance of females (51 percent). Fifteen patients (30.6 percent) presented major life-threatening signs, 32 (65.3 percent) minor systemic manifestations, and two (4.1 percent) only local manifestations. Left ventricular dysfunction was identified in 13 patients (26.5 percent). Ten patients (20.4 percent) presented pattern B (visualization of three or more B lines in the evaluated quadrant) in at least one lung window. The sensitivity and specificity of cardiac and pulmonary ultrasound to identify the most severely ill patients were 86 percent and 94 percent, respectively. DISCUSSION: The changes found on point-of-care ultrasound were associated with life-threatening signs. All patients with class III envenomation were referred to the intensive care unit, showing the importance of early identification of this subgroup. The main limitations were the small sample size and the fact that admission to intensive care was not based on systematic criteria. CONCLUSIONS: Point-of-care ultrasound is able to identify early signs of pulmonary congestion and heart failure in scorpionism. It can be useful for the objective selection of patients who are at a higher risk of complications and death and who require intensive support; it may also be valuable for periodic reassessments. Point-of-care ultrasound is a valuable tool for identifying and monitoring severe cases of scorpionism.

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.

Epidemiology of scorpion stings in the West Bank, occupied Palestinian territory

Background:Scorpionism (scorpion sting envenoming) is an endemic public health concern in many Arab Middle Eastern countries. However, our knowledge of the epidemiology of scorpion stings in the West Bank is limited.Aim:To investigate the epidemiology of scorpion stings in 4 districts of the West Bank over a specified period.Methods:We obtained scorpion sting records from the main hospitals in 4 districts of the West Bank for 2012 and 2014–2020. A total of 2175 cases were analyzed retrospectively using SPSS version 17.Results:The average age and standard deviation (±SD) for both sexes was 24.7±17.5 years (22.7±16.5 and 27.1±18.4 years for males and females, respectively). The median age was 20 years and 47.2% were children under 18 years. Most cases were reported during the summer months, between June and October, with a peak in July–August. By anatomic site, the right hand was the most commonly stung in both sexes, followed by the right foot. The chest, buttocks and scrotum were the least affected body parts. Clinical data were available for 405 cases, in which pain, vomiting and sweating were the most common symptoms. The overall incidence of stings was 26.32 per 100 000 inhabitants per year over the study period of 8 years (59.21–171.67, 95% CI).Conclusion:Scorpion stings are commonly encountered by adults and children in the West Bank. There is a need for awareness among the West Bank populations on how to avoid being stung, to train medical staff to better manage sting cases, and to evaluate the antivenom currently being used by physicians for scorpion stings.

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.

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.
