Envenomation by a common green racer (Chlorosoma viridissimum) in the Brazilian Amazon: A report of three cases.

Envenomations by the common green racer (Chlorosoma viridissimum) are seldom reported in the literature. Herein, we report three cases caused by the same specimen of C. viridissimum in three different victims in the Brazilian Amazon. In all cases, the victims were either a biologist or biology students that were handling the animal and were bitten in their upper limbs. The victims showed only local symptoms, such as edema, tooth marks, pain, erythema, ecchymoses and bleeding. One of the patients presented extensive ecchymosis. Two patients sought medical care, but were only treated for local manifestations and evolved without complications. Chlorosoma viridissimum is capable of provoking mild to moderate signs and symptoms.

"Two Cultures in Favor of a Dying Patient": Experiences of Health Care Professionals Providing Snakebite Care to Indigenous Peoples in the Brazilian Amazon.

In the Brazilian Amazon, deaths and disabilities from snakebite envenomations (SBEs) are a major and neglected problem for the indigenous population. However, minimal research has been conducted on how indigenous peoples access and utilize the health system for snakebite treatment. A qualitative study was conducted to understand the experiences of health care professionals (HCPs) who provide biomedical care to indigenous peoples with SBEs in the Brazilian Amazon. Focus group discussions (FGDs) were carried out in the context of a three-day training session for HCPs who work for the Indigenous Health Care Subsystem. A total of 56 HCPs participated, 27 in Boa Vista and 29 in Manaus. Thematic analysis resulted in three key findings: Indigenous peoples are amenable to receiving antivenom but not to leaving their villages for hospitals; HCPs require antivenom and additional resources to improve patient care; and HCPs strongly recommend a joint, bicultural approach to SBE treatment. Decentralizing antivenom to local health units addresses the central barriers identified in this study (e.g., resistance to hospitals, transportation). The vast diversity of ethnicities in the Brazilian Amazon will be a challenge, and additional studies should be conducted regarding preparing HCPs to work in intercultural contexts.

Crouching Zookeeper, Hidden Dragon: A Case of a Komodo Dragon Bite.

BACKGROUND: The Komodo dragon (Varanus komodoensis) is the world's largest living lizard and exists in private captivity worldwide. Bites to humans are rare and have been proposed to be both infectious and venomous. CASE REPORT: A 43-year-old zookeeper was bitten on the leg by a Komodo dragon and suffered local tissue damage with no excessive bleeding or systemic symptoms to suggest envenomation. No specific therapy was administered other than local wound irrigation. The patient was placed on prophylactic antibiotics and on follow-up, which revealed no local or systemic infections, and no other systemic complaints. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although venomous lizard bites are uncommon, prompt recognition of possible envenomation and management of these bites is important. Komodo dragon bites may produce not only superficial lacerations but also deep tissue injury, but are unlikely to produce serious systemic effects; whereas Gila monster and beaded lizard bites may cause delayed angioedema, hypotension, and other systemic symptoms. Treatment in all cases is supportive.

Clinical Presentations, Treatments, and Outcomes of Non-native Snake Envenomations in the United States Reported in the North American Snakebite Registry.

BACKGROUND: Non-native snake envenomations in the United States are uncommon with much unknown about a patient's presenting signs and symptoms. Antivenoms for non-native snake envenomations are not typically available in hospital pharmacies which may limit their administration. What are the clinical presentations, treatments, and outcomes of non-native snake envenomation cases reported to the North American Snakebite Registry (NASBR) of the Toxicology Investigators Consortium (ToxIC)? METHODS: This is a descriptive review of all non-native envenomations reported to the NASBR from 2013 to March 2022. Data abstracted included snake species, patient history, clinical signs, diagnostics, treatment (including antivenom usage), follow-up, and final outcome. RESULTS: We identified 19 non-native snake envenomations resulting from encounters with eleven different species, eight of which belonged to the Viperidae family. The most common presenting symptoms were edema (18 patients), ecchymosis (seven patients), and necrosis (six patients). Systemic effects and hematologic abnormalities were less common. The most common treatments were extremity elevation and analgesia, with two patients receiving mechanical ventilation. Ten patients received antivenom. No patients died. Three patients had loss of mobility in a digit at the last follow-up visit. One patient had permanent tissue loss of a small area on a finger. CONCLUSIONS: The results of this study suggest that non-native snake envenomations in the United States frequently cause local soft tissue effects and less frequently cause systemic or hematologic effects. Most patients received antivenom, although several patients envenomated by snakes for which a specific antivenom exists did not receive any. Sequelae at the last follow-up of such encounters consisted of local mobility deficits.

Perceptions of nurses regarding the management of snakebite envenomations: Limits and possibilities.

Snakebites can be caused by harmless or venomous snakes and, according to their severity and frequency, can be considered events of medical importance. In health facilities in remote areas, nurses work in the first line of care of patients that are victims of these envenomations. The aim was to discover the perception of nurses regarding the management of snakebites, its limitations and possibilities, with a view to professional empowerment in the context of primary health care. This is exploratory and descriptive research, with a qualitative approach, developed at FMT-HVD in Manaus, Amazonas state, Brazil, in the year 2021. The participants were nurses who work in basic health units in the municipalities of Careiro da Várzea, Ipixuna and Boa Vista do Ramos in the state of Amazonas. For data collection, the focus group strategy was adopted. Thematic content analysis was employed, which was carried out in the stages of pre-analysis; exploration or coding of the material; treatment of the results, inference and interpretation. After processing the data obtained, four topics emerged from the coding: Topic 1 - limitations in the primary care. Topic 2 - the need for infrastructure and personnel. Topic 3 - the need for continuing education. Topic 4 - the perception of training regarding the management of snakebite envenomations. The results showed a lack of antivenom in the healthcare units where nurses work. Another aspect highlighted by the nurses is the absence of a doctor in situ to perform the primary care or out of hours care in the units. The nurses' perceptions regarding the management of snakebite envenomations revealed the existence of failures in relation to the subject, such as the lack of antivenom, poor infrastructure in the units and the lack of a doctor, which must be solved, since the nurses are the most active professionals in primary health care, in addition to the high incidence of snakebite envenomations in the Brazilian Amazon.

Discovery of a novel jellyfish venom metalloproteinase inhibitor from secondary metabolites isolated from jellyfish-derived fungus Aspergillus versicolor SmT07.

The major jellyfish stings that occur in China are caused by scyphozoan Nemopilema nomurai, whose venom exhibits significant metalloproteinase activity that contributes to the toxic effects of jellyfish envenomation. Researching effective inhibitors suppressing the metalloproteinase activity of jellyfish venom represents a new attempt to cure jellyfish envenomations. In the present study, secondary metabolites produced by the jellyfish-associated fungus Aspergillus versicolor SmT07 were isolated and evaluated for their anti-proteolytic activities. Two xanthones, sterigmatocystin (JC-01) and oxisterigmatocystin C (JC-06), and four alkaloids, cottoquinazoline A (JC-02), phenazine-1-carboxylic acid (JC-03), viridicatin (JC-04) and viridicatol (JC-05), were isolated and identified. Only phenazine-1-carboxylic acid (PCA) showed significant anti-proteolytic activity of jellyfish venom assayed on azocasein, and the IC50 value was 2.16 mM. PCA also significantly inhibited fibrinogenolytic activity, protecting the Bß chain of fibrinogen from degradation when preincubated with jellyfish venom at a ratio of >1:0.6 (PCA:venom, w/w). Molecular docking with several well-characterized snake venom metalloproteinases suggested the venom metalloproteinases inhibitory property of PCA by forming complex interactions with the active site via hydrogen bonds, π-π stacking and salt bridges, which was distinct from the binding mode of batimastat. The present study represents the first study identifying natural jellyfish venom metalloproteinase inhibitors from marine natural products, which may provide an alternative to develop therapeutic agents for treating jellyfish envenomations.

North American Envenomation Syndromes.

This review discusses the distinct envenomation syndromes produced by North American species of snakes and arthropods, specifically the Crotalinae subfamily of snakes, which includes cottonmouths, copperheads, and rattlesnakes; coral snakes; Latrodectus and Loxosceles species of arachnid; and Centruroides sculpturatus, the only species of North American scorpion capable of producing an envenomation syndrome. The authors discuss the epidemiology, pathophysiology, and presentation of these syndromes and emphasize the varying degrees to which these syndromes can manifest clinically. Finally, the management of each envenomation syndrome is addressed. Special attention is paid to available antivenoms, their indications for use, and their side effects.

Hemorrhagic Stroke Revealing a Snake Bite: A Case Report.

In Morocco, envenomations caused by viper bites and scorpion stings are frequent and associated with high lethality. It occurs mainly during the summer season with a peak between June and August. It is a medical emergency requiring intensive care. It is a life-threatening disease mainly due to the systemic hemorrhagic syndrome. Here, we present the clinical course of a patient in his 50s who suffered a snakebite and describe the neurological sequelae. The patient was admitted to the emergency room in a state of unconsciousness with gangrene on the right foot. An emergency brain scan showed meningeal hemorrhage and intracerebral hematomas. The biological assessment revealed disseminated intravascular coagulation. The evolution of the clinical course was rapidly unfavorable and the patient died within 24 hours of admission.

First step in assessment of VipGrade®, a computerized clinical decision system to assess Vipera envenomation grading: a single-center interrater reliability study.

METHODS: We conducted a retrospective review of Vipera spp. snakebite cases registered by the PCC of Bordeaux, France, between January 1, 2018, and December 31, 2020, evaluating the agreement between VipGrade® assessments, toxicologists' assessments, and current guidelines. RESULTS: 133 patients with Vipera aspis snakebites were included. There was 100% agreement in severity grading by PCC guidelines and VipGrade®. However, grading by toxicologists and VipGrade® diverged in 19 cases (85% agreement; κ = 0.80; 95% CI: 0.71 to 0.87). CONCLUSIONS: The VipGrade® tool's grading reflects current PCC guidelines, which are authoritative in France, and may allow for a more rapid and standardized determination of management and follow-up of viper-bitten patients. It should be noted, however, that the more complex and dynamic aspects of management are not included in VipGrade®. Its purpose is to supplement, not replace, the advice of the PCC's clinical toxicologists, and this advice should be sought whenever a viper bite is encountered in clinical practice.

Curses or Cures: A Review of the Numerous Benefits Versus the Biosecurity Concerns of Conotoxin Research.

Conotoxins form a diverse group of peptide toxins found in the venom of predatory marine cone snails. Decades of conotoxin research have provided numerous measurable scientific and societal benefits. These include their use as a drug, diagnostic agent, drug leads, and research tools in neuroscience, pharmacology, biochemistry, structural biology, and molecular evolution. Human envenomations by cone snails are rare but can be fatal. Death by envenomation is likely caused by a small set of toxins that induce muscle paralysis of the diaphragm, resulting in respiratory arrest. The potency of these toxins led to concerns regarding the potential development and use of conotoxins as biological weapons. To address this, various regulatory measures have been introduced that limit the use and access of conotoxins within the research community. Some of these regulations apply to all of the ≈200,000 conotoxins predicted to exist in nature of which less than 0.05% are estimated to have any significant toxicity in humans. In this review we provide an overview of the many benefits of conotoxin research, and contrast these to the perceived biosecurity concerns of conotoxins and research thereof.

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.

[Acute Complications Of Snakebite Envenomation In Department Resuscitation Of CHU-Mother Child "Luxembourg" Of Bamako]. / Complications Aigues De L'Envenimation Par Morsures De Serpent Au Service De Reanimation Du Chu Mere Enfant "Le Luxembourg" De Bamako.

Envenomation by snakebite remains a public health problem in Africa. The purpose of our work was to study the acute complications of snakebite envenomation and the risk factors for its complications. METHOD: This was a retrospective and prospective study over a period of 07 years, which was performed in the department of anesthesia resuscitation and emergencies of CHU-Mother Child "Luxembourg" of Bamako. RESULTS: During this period, 76 cases of Ophidian envenomation were recorded. The average age of the patients was 34 ± 12 years old. . The family of vipers (Echis and Bitis) was the most incriminated 84,61% of the cases. Hemorrhagic complications were observed in 78.94% of patients, other complications (cardiovascular, neurological, dermatological, ophthalmological ...) were observed in 21.05% of patients. The main risk factor for complication observed was the delay in management (> 6 hours delay) in 100% of patients. The absence of serotherapy and or the initial resort to traditional treatment have been complicating risk factors. Almost all victims of Elapidae bites, 89.9% (5/6 cases) died. Serotherapy was performed urgently in 97.4% of cases. The morbidity in our study was 10.52% with a 7.8% mortality. CONCLUSION: in our context, the management of envenomations by snake bite remains dependent on a multitude of complications. The prognosis is conditioned by the early administration of symptomatic treatment and a specific antidote.

Evaluation of Cyanea capillata Sting Management Protocols Using Ex Vivo and In Vitro Envenomation Models.

Lion's mane jellyfish (Cyanea capillata) stings cause severe pain and can lead to dangerous systemic effects, including Irukandji-like syndrome. As is the case for most cnidarian stings, recommended medical protocols in response to such stings lack rigorous scientific support. In this study, we sought to evaluate potential first aid care protocols using previously described envenomation models that allow for direct measurements of venom activity. We found that seawater rinsing, the most commonly recommended method of tentacle removal for this species, induced significant increases in venom delivery, while rinsing with vinegar or Sting No More® Spray did not. Post-sting temperature treatments affected sting severity, with 40 min of hot-pack treatment reducing lysis of sheep's blood (in agar plates), a direct representation of venom load, by over 90%. Ice pack treatment had no effect on sting severity. These results indicate that sting management protocols for Cyanea need to be revised immediately to discontinue rinsing with seawater and include the use of heat treatment.

Accidentes y muertes por animales venenosos en Argentina durante el período 2000- 2011 / Accidents and deaths by venomous animals in Argentina during the period 2000-2011

En Argentina los accidentes causados por animales venenosos constituyen un problema de salud pública. En este estudio analizamos los accidentes y muertes por envenenamientos por mordedura o picadura de serpientes, escorpiones y arañas, y las muertes causadas por abejas- avispas-avispones, centípedos, animales marinos, otros artrópodos y otros animales venenosos en Argentina, recibidos por las autoridades sanitarias nacionales. Se analizó la información sobre accidentes y muertes producidas por este tipo de animales que fueron recibidas por el Ministerio de Salud de la Nación durante el período 2000-2011. Debido al tipo de sistema de notificación solo se pudieron calcular tasas de morbilidad y letalidad en los accidentes por arañas, escorpiones y serpientes. Contrariamente a lo que se suponía, no fueron estos los grupos que mayor cantidad de muertes causaron en el período de estudio, sino los himenópteros (abejas-avispas- avispones). El actual esquema de notificación de envenenamiento por animales venenosos provee información importante para el sistema sanitario. Sin embargo, deben realizarse modificaciones a fin de mejorar el conocimiento epidemiológico referente a envenenamientos por la mordedura o picadura de animales venenosos. De esta manera, se podrá progresar en la implementación de las medidas de prevención de estas patologías, su atención a nivel del primer nivel asistencial y la planificación de la producción de antivenenos.

In Argentina, accidents by venomous animals are a problem of public health. In this study we analyzed the envenomation caused by the bite or sting of snakes, scorpions and spiders and the deaths produced by the envenomation caused by this animals and the deaths caused by bees-wasp-hornet, centipedes, marine animals, other arthropods and other venomous animals in Argentina, recorded by the National Ministry of Health in the period 2000 ­ 2011. Most of the accidents were caused by scorpions nevertheless the highest lethality was observed in snakebites envenomation. Contrary to the general suppositions, hymenoptera (bee-wasp- hornet) were the responsible for the highest number of deaths. The present system of information of envenomation by venomous animals gives important information. However some modifications should be done to achieve a best knowledge of the epidemiological situation of the envenomation caused by bites or sting of the different venomous animals, in order to improve the prevention measures as well as the attention at the first level of sanitary assistance and the planning of antivenom production.

Report of 15 injuries caused by lionfish (pterois volitans) in aquarists in Brazil: a critical assessment of the severity of envenomations.

Lionfish are venomous fish that belong to the Scorpaenidae family. Individuals of this family and those of the Synanceiidae family comprise most of the existing venomous fish in the world. Lionfish are originally found in the Indo-Pacific, but they have received special attention in the last years for their dissemination in the Atlantic Ocean, with the emergence of large populations in the USA, Caribbean and South America. Because of its beauty, this fish has always been present in private and commercial aquariums around the world. Herein, we describe 15 envenomations in aquarists registered in a period of eighteen years (1997-2014). The stings caused excruciating pain and marked inflammation, with local erythema, edema, heat, paleness and cyanosis. In one case, it was possible to observe vesicles and blisters. There were no skin necroses or marked systemic manifestations. We discuss the possible coming of the fish to South America and the circumstances and clinical impact of the envenomations.

Incidence and characteristics of snakebite envenomations in the New York state between 2000 and 2010.

OBJECTIVE: We sought to evaluate the incidence of reported venomous snakebites in the state of New York between 2000 and 2010. METHODS: Data were collected retrospectively from the National Poison Data System (NPDS) and then reviewed for species identification and clinical outcome while using proxy measures to determine incidence of envenomation. RESULTS: From 2000 to 2010 there were 473 snakebites reported to the 5 Poison Control Centers in the state of New York. Venomous snakes accounted for 14.2% (67 of 473) of these bites. Only 35 bites (7%) required antivenom. The median age of those bitten by a venomous snake was 33. Most victims were male. CONCLUSIONS: Although not rare, venomous snakebites do not occur commonly in New York State, with a mean of just 7 bites per year; fortunately most snakebites reported are from nonvenomous snakes. Yet even nonvenomous bites have the potential to cause moderately severe outcomes. Medical providers in the state should be aware of their management.

Long-term complications of rattlesnake bites: a telephone survey from Central California.

OBJECTIVE: The purpose of this institutional review board-approved, cross-sectional study was to identify residual symptoms and signs of envenomation reported by snakebite survivors via a telephone survey. METHODS: Victims of rattlesnake bite who were treated at a single hospital center during a 10-year period were contacted through a telephone survey. Study subjects were included through a diagnosis-based retrospective chart review of snakebite victims, and excluded if they did not receive rattlesnake antivenom. Data collection was done using a standardized form that included sections about residual, recurrent, or new pain, weakness, paresthesias, or other limitations of the bitten limb. RESULTS: We identified 46 snakebite cases including 5 of 46 "dry" bites. The remaining cases (41 of 46) all received Crofab. Interviews were completed for 31% of these patients (13 of 41), and the remainder were lost to follow-up. Most bites occurred in men (12 cases, 92% males) and on the arms (9 cases, 69%). Six of the 13 respondents (46%) reported residual symptoms from the bite. Persistent symptoms described included localized pain at the bite site (3 cases), numbness or paresthesias (2 cases), abnormal skin peeling and discoloration at the bite site (2 cases), and persistent weakness of the bitten extremity (1 case). Among patients reporting persistent symptoms, the bite-to-survey interval ranged from 7 months to 12 years, with a median interval of 4 years. CONCLUSIONS: Our study population demonstrated a notable incidence (43%) of self-reported persistent symptoms related to their rattlesnake bites, although the overall level of disability from these injuries seems low.
