Toad envenoming in dogs: effects and treatment
Provedor de dados: Journal of Venomous Animals and Toxins
Autores: SAKATE,M.; OLIVEIRA,P. C. LUCAS DE.
Toads (order: Anura; family: Bufonidae; genus: Bufo) are distributed throughout the world, but more species are found in areas of tropical and humid temperate climates. Although toads do not have a venom inoculation system, they are venomous animals because the glands covering the whole surface of their bodies secrete a milk-like venom of which composition is not yet completely known. Some of these glands are the bilateral glands located in post-orbital position. These glands, which are somewhat diamond-shaped and can be seen by the naked eye, are known as parotids. Toad envenoming in dogs may cause local and systemic alterations and may cause death by cardiac ventricular fibrillation. The electrocardiographic alterations observed consist of gradual...

Use of lidocaine, propranolol, amiodarone, and verapamil in toad envenoming (genus bufo) in dogs
Provedor de dados: Journal of Venomous Animals and Toxins
Autores: SAKATE,M.; OLIVEIRA,P. C. LUCAS DE.
Toad envenoming in dogs can cause death by cardiac fibrilation (CVF). Traditional therapy consists mainly of atropine and propranolol, the last one used to prevent the CVF, that is preceded by negative ventricular deflections (NVDs) in the QRS complex of the electrocardiogram. This study intended to verify, comparatively, the lidocaine, propranolol, amiodarone, and verapamil abilities to prevent CVF in experimentally envenomed dogs. Thirty-six dogs were divided into 6 groups (GL, GP, GA, GV, GST, and GSV) with n=6; the dogs were submitted to volatile anaesthesia. The animals of the groups GL, GP, GA, and GV received 0.38g of toad venom through oro-gastric catheter and were treated with the following drugs respectively: lidocaine (4mg/Kg), propranolol...

Autores: Laïd,Y; Boutekdjiret,L; Oudjehane,R; Laraba-Djebari,F; Hellal,H; Guerinik,M; Griene,L; Alamir,B; Merad,R; Chippaux,JP.
Scorpion stings are a public health problem in the Maghreb region. In Algeria, epidemiological data were collected over the past twenty years by the Algerian health authorities. This study is an analysis of morbidity and mortality data collected from 2001 to 2010. Annual incidence and mortality due to scorpion envenoming were 152 ± 3.6 stings and 0.236 ± 0.041 deaths per 100,000 people (95% CI), respectively. The risk of being stung by a scorpion was dramatically higher in southern areas and central highlands due to environmental conditions. Incidence of envenoming was especially higher in the adult population, and among young males. In contrast, mortality was significantly higher among children under 15 years, particularly ages 1-4. Upper limbs were more...

Toxicity of puffer fish: two species (Lagocephalus laevigatus, linaeus 1766 and Sphoeroides spengleri, Bloch 1785) from the Southeastern Brazilian coast
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Oliveira,J. S.; Pires Junior,O. R.; Morales,R. A. V.; Bloch Junior,C.; Schwartz,C. A.; Freitas,J. C.
In Brazil, where puffer fish are considered poisonous, there are few documented cases on human consumption and consequent poisoning. In this study, toxicity of two puffer fish species from the Brazilian coast was examined. Specimens of Sphoeroides spengleri and Lagocephalus laevigatus were caught in São Sebastião Channel (North coast of São Paulo State, Brazil) between January 1996 and May 1997. Acidic ethanol extracts from muscle and skin plus viscera were tested for mice acute toxicity using the standard method of Kawabata. Polar extracts of S. spengleri showed high toxicity up to 946 MU/g. Extracts from L. laevigatus showed very low levels of toxicity, never exceeding 1.7 MU/g. All extracts from both species blocked amielinic nerve fiber evoked impulses...

Public health aspects of snakebite care in West Africa: perspectives from Nigeria
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Habib,Abdulrazaq G.
Snakebite envenoming is a major public health problem among rural communities of the Nigerian savanna. The saw-scaled or carpet viper (Echis ocellatus) and, to a lesser extent, the African cobras (Naja spp.) and puff adders (Bitis arietans) have proved to be the most important cause of mortality and morbidity. The main clinical features of E. ocellatus envenoming are systemic hemorrhage, incoagulable blood, shock, local swelling, bleeding and, occasionally, necrosis. Bites may be complicated by amputation, blindness, disability, disfigurement, mutilation, tissue destruction and psychological consequences. Antivenom remains the hallmark and mainstay of envenoming management while studies in Nigeria confirm its protection of over 80% against mortality from...

Hump-nosed viper bite: an important but under-recognized cause of systemic envenoming
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Shivanthan,Mitrakrishnan Chrishan; Yudhishdran,Jevon; Navinan,Rayno; Rajapakse,Senaka.
Hump-nosed viper bites are common in the Indian subcontinent. In the past, hump-nosed vipers (Hypnalespecies) were considered moderately venomous snakes whose bites result mainly in local envenoming. However, a variety of severe local effects, hemostatic dysfunction, microangiopathic hemolysis, kidney injury and death have been reported following envenoming byHypnalespecies. We systematically reviewed the medical literature on the epidemiology, toxin profile, diagnosis, and clinical, laboratory and postmortem features of hump-nosed viper envenoming, and highlight the need for development of an effective antivenom.

Current challenges for confronting the public health problem of snakebite envenoming in Central America
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Gutiérrez,José María.
Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally known as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further...

True or false coral snake: is it worth the risk? A Micrurus corallinus case report
Provedor de dados: Journal of Venomous Animals and Toxins Including Tropical Diseases
Autores: Strauch,Marcelo Abrahão; Souza,Guilherme Jones; Pereira,Jordana Nahar; Ramos,Tyelli dos Santos; Cesar,Marcelo Oliveira; Tomaz,Marcelo Amorim; Monteiro-Machado,Marcos; Patrão-Neto,Fernando Chagas; Melo,Paulo A.
Abstract  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...

Autores: SILVA,Ageane Mota da; COLOMBINI,Mônica; MOURA-DA-SILVA,Ana Maria; SOUZA,Rodrigo Medeiros de; MONTEIRO,Wuelton Marcelo; BERNARDE,Paulo Sérgio.
ABSTRACT This study addresses the clinical and epidemiological aspects of envenoming cases resulting from snakebites treated at a hospital in Cruzeiro do Sul, in the upper Juruá River region, western Brazilian Amazonia. The specific identity of snakes that caused the envenomings was inferred (a) from the diagnosis of patient symptoms and signs upon hospital admission, (b) by enzyme immunoassay for detection of Bothrops atrox and Lachesis muta venom from serum samples taken from patients before antivenom therapy, or (c) by direct identification of the snake, when it was brought along to the hospital or photographed. There were 133 snakebites (76.2 cases per 100,000 inhabitants) registered during one year (July 2017 to June 2018). Most snakebites (88.7%)...
