Abscess secondary to facial snakebite
Provedor de dados: 79
Autores: QUIROGA,M.; AVILA-AGÜERO,M. L.; FAINGEZICHT,I.
In Costa Rica, approximately 700 snakebite cases occur each year, 5 to 10 of which result in death. At the Hospital Nacional de Niños (HNN), 6 to 10 cases are reported annually, more than half of these cases and nearly all deaths are result from Bothrops asper snakebite. This venomous snake, popularly known as the "terciopelo", most often attacks the lower or upper limbs and characteristically produces local tissue damage, which can be severe. The following is a report of the first case of a non-fatal and unusual facial bite caused by Bothrops asper in our country.

VIPER ENVENOMING: EVALUATION OF TREATMENT BY RESTORATION OF HAEMOSTASIS AND VENOM CLEARANCE
Provedor de dados: 79
Autores: THEAKSTON,R. D. G.; KAMIGUTI,A. S.
Treatment of systemic envenoming in snakebite victims has, in the past, depended almost entirely on the individual clinician's experience in assessing the severity of envenoming. The efficacy of treatment is obviously related to the neutralising potency of the antivenom used, the route by which it is administered and the dose. The use of techniques for evaluating the efficacy of antivenoms has proved to be very useful, as an adjunct to recognised clinical observations, for a more objective evaluation of antivenom efficacy and dosage. In patients bitten by many vipers, including the Brazilian pit vipers, the reversal of the venom-induced coagulopathy provides an ideal indicator as to the efficacy of an antivenom. Likewise, the development of enzyme...

Snakebites in southern Minas Gerais State, Brazil
Provedor de dados: 79
Autores: FRANCO,R. L.; ROCHA,C. C.; JORGE,M. T.; RIBEIRO,L.A.
In Brazil, more than 80% of venomous snakebites are caused by Bothrops and about 10% by Crotalus. This study evaluated 133 reported cases that occurred between 1994 and 1996 in the 52 municipalities covered by the Pouso Alegre Regional Health Center in southern Minas Gerais State. Most of the patients were male (89.5%). The most frequently attacked age bracket was that of people in their twenties, and the most frequently bitten anatomical regions were the lower limbs (77.7%), principally the feet (34.6%). Of the 124 cases stating the snake genus, 62.9% were caused by Crotalus and 37.1% by Bothrops. The conclusion of this study is that although the epidemiology of snakebites in Minas Gerais State is similar to other regions of the country, the percentage of...

INFECTIONS IN THE BITE SITE AFTER ENVENOMING  BY SNAKES OF THE Bothrops GENUS
Provedor de dados: 79
Autores: JORGE,M. T.; RIBEIRO,L. A.
Envenomation caused by snakes of the Bothrops genus produces a lesion in the bite site and can result in extensive necrosis. The dead tissue can be secondarily infected by bacteria that come from the snake, and the bacteria can be inoculated at the moment of the bite. The bacteria that most commonly cause infection are the enterobacteria, mainly Morganella morganii, Proteus rettgeri, Enterobacter sp., and Escherichia coli. Group D streptococci including here Enterococcus sp. and the Bacteroides sp. are also involved. Based on a study of the sensibility of these bacteria, it has been suggested that this infection must be treated with chloramphenicol, as a sole antimicrobial agent, or with the combinations of benzylpenicillin or ampicillin with...

Deinagkistrodon acutus envenomation: a report of three cases
Provedor de dados: 80
Autores: Cheng,Chin-Lung; Mao,Yan-Chiao; Liu,Po-Yu; Chiang,Liao-Chun; Liao,Shu-Chen; Yang,Chen-Chang.
Abstract  Background Deinagkistrodon acutus envenomation is associated with severe hematological and wound complications but is rarely described.  Case presentation  Herein, we report three cases of victims bitten by D. acutus and indicate that rapid-onset severe coagulopathy and thrombocytopenia are distinct features of D. acutus snakebite, which are not observed in other crotaline snakebites (i.e., Trimeresurus stejnegeri and Protobothrops mucrosquamatus) in Taiwan. The toxic effects could occur as early as 2 to 3 h following D. acutus envenomation and persist if the administration of specific antivenom is delayed or even not commenced. Based on our findings, 2 to 4 vials of specific antivenom as the first dose should be administered to victims and...

Morphometric characteristics and seasonal proximity to water of the Cypriot bluntnosed viper Macrovipera lebetina lebetina (Linnaeus, 1758)
Provedor de dados: 80
Autores: Jestrzemski,Daniel; Kuzyakova,Irina.
Abstract  Background: The blunt-nosed viper Macrovipera lebetina (Linnaeus, 1758) is a medically important snake species in the Middle East. Its nominate subspecies Macrovipera l. lebetina is confined to Cyprus, where it is the only dangerously venomous snake species and heavily pursued. Despite the viper's large size, data on its body mass and sex-specific morphological differences are scarce. It is commonly believed that M. l. lebetina prefers freshwater proximity during summer. Hence, we aimed at investigating M. l. lebetina sex-specific morphological differences and its possible attraction to freshwater bodies in late summer.  Methods: Morphometric characteristics, proximity to water and conservation status of M. l. lebetina were investigated in Paphos...

Uveitis following anti-snake venom therapy
Provedor de dados: 80
Autores: Nayak,S. G.; Satish,R.; Nityanandam,S.; Thomas,R. K.
Snakebite is a common medical emergency in the tropics, causing multisystemic involvement. Ophthalmic manifestations after snakebite have included ptosis and ophthalmoplegia. Uveitis as an immunological complication following therapy with anti-snake venom (ASV) serum has been rarely reported in literature. We reported two patients who developed uveitis and acute renal failure following snakebite treatment with ASV serum. Both patients recovered uneventfully with appropriate therapy.

Autores: Huang,Li-Wen; Wang,Jiaan-Der; Huang,Jin-An; Hu,Sung-Yuan; Wang,Lee-Min; Tsan,Yu-Tse.
There are very few microbiological data on wound infections following snakebites. The objective of this study was to investigate the treatment of secondary infection following snakebites in central Taiwan. Microbiological data and antibiotic sensitivity of wound cultures were retrospectively analyzed from December 2005 to October 2007 in a medical center in central Taiwan. A total of 121 snakebite patients participated in the study. Forty-nine (40.5%) subjects were bitten by cobra (Naja atra); 34 of them had secondary infection, and 24 of them (70.6%) needed surgical intervention. Cobra bites caused more severe bacterial infection than other snakebites. Morganella morganii was the most common pathogen, followed by Aeromonas hydrophila and Enterococcus....

Delayed double reading of whole blood clotting test (WBCT) results at 20 and 30 minutes enhances diagnosis and treatment of viper evenomation
Provedor de dados: 80
Autores: Benjamin,Jordan Max; Chippaux,Jean-Philippe; Sambo,Bio Tamou; Massougbodji,Achille.
Abstract  Background The whole blood clotting test (WBCT) is a simple test of coagulation that is often used in the assessment, diagnosis, and therapeutic monitoring of snakebite patients in sub-Saharan Africa. WBCT requires only a clean glass tube and several milliliters of venous blood and is ideal for use in poorly equipped health centers throughout the rural areas where 95% of snakebites occur. However, questions surrounding the accuracy and reliability of the test remain unanswered due to variations in testing conditions and a lack of comparative research with which to validate them. This is the first study to evaluate WBCT results at both 20-min (WBCT20) and 30-min (WBCT30) reading times in the same group of snakebite patients.  Methods In order to...

Viper bites complicate chronic agrochemical nephropathy in rural Sri Lanka
Provedor de dados: 80
Autores: Silva,Anjana; Samarasinghe,Rivikelum; Pilapitiya,Senaka; Dahanayake,Niroshana; Siribaddana,Sisira.
Snakebite is a common occupational health hazard among Sri Lankan agricultural workers, particularly in the North Central Province. Viperine snakes, mainly Russell’s viper envenomation, frequently lead to acute renal failure. During the last two decades, an agrochemical nephropathy, a chronic tubulointerstitial disease has rapidly spread over this area leading to high morbidity and mortality. Most of the epidemiological characteristics of these two conditions overlap, increasing the chances of co-occurrence. Herein, we describe four representative cases of viperine snakebites leading to variable clinical presentations, in patients with chronic agrochemical nephropathy, including two patients presented with acute and delayed anuria. These cases suggest the...

We report herein the case of 19-year-old female farmer who suffered a double snakebite on the right foot. After an unsuccessful traditional treatment, she consulted a health center, 48 hours after the bite. Upon arrival at the hospital, she showed signs of severe damage, including hemorrhagic syndrome, extensive gangrene of the bitten limb and severe acute renal failure. Due to financial constraints, neither antivenom nor the scheduled amputation was performed. After 35 days of hospitalization, she returned home, against the advice of medical personnel. Our case summarizes the daily challenges of patients and practitioners that suffer snakebite envenomation in Bobo-Dioulasso, western Burkina Faso.

Fatal neurotoxic envenomation following the bite of a greater black krait (Bungarus niger) in Nepal: a case report
Provedor de dados: 80
Autores: Pandey,Deb Prasad; Sharma,Sanjib Kumar; Alirol,Emilie; Chappuis,François; Kuch,Ulrich.
Abstract  Background  Neurotoxic envenomation following bites by kraits (Bungarus species) is a leading cause of snakebite mortality in South Asia. Over a long time, this had been attributed only to one species, the common krait (Bungarus caeruleus). However, recent research has provided increasing evidence of the involvement of several krait species. Here, we report a fatal case of neurotoxic envenomation following the bite of a greater black krait (Bungarus niger) in Nepal.  Case presentation  A 33-year-old man was bitten in the outdoor corridor of his home in the eastern hills of Ilam district while handling a snake he thought to be non-venomous. He subsequently developed severe abdominal pain, frequent vomiting, and signs of neurotoxic envenomation...

In tropical countries like Bangladesh, persons are bitten by snakes every day and a considerable number of patients die en route to the hospital. An event of consecutive neurotoxic bites on two men by a single snake was observed in the Snake Bite Study Clinic (SBSC) of the Chittagong Medical College Hospital (CMCH). Two brothers, working in their semi-pucca restaurant, were successively bitten by the same cobra on their lower limbs. Within an hour, they were taken to the CMCH. Few minutes after admission, both developed symptoms of neurotoxicity: ptosis, nasal voice, dysphagia, broken neck sign, etc. They received polyvalent antivenom (Haffkine Bio-Pharmaceuticals Company, India) and other auxiliary treatment immediately. Within few hours, neurotoxic...

Abstract  Background  The five-paced pit viper (Deinagkistrodon acutus), endemic to China and northern Vietnam, is responsible for most snakebites in the Chinese territory. Antivenom produced from horses is the main treatment for snakebites, but it may cause numerous clinical side effects and have other disadvantages involved in their production such as the welfare of animals. The present study was conducted aiming to develop an alternative antibody (IgY) from the egg yolk of leghorn chickens immunized with snake venom.  Methods  IgY from the egg yolk of white leghorn chickens previously immunized intramuscularly with D. acutus venom was extracted by water, precipitated by ammonium sulfate and purified by affinity chromatographic system. IgY was identified...

A better understanding of the epidemiology of envenoming would improve care, provided that the survey is representative, reliable and accurate. Several types of surveys could help to clarify the incidence, severity, circumstances, factors and determinants of envenomations. The relevant information may be collected and analyzed from hospital records or case report forms (for retrospective studies) or established from a protocol of longitudinal observation of cases attended at health facilities during a given period (prospective study). The household survey includes interviewing all or part of the population of a locality with a standardized questionnaire to obtain information on the circumstances of the accident.

Abstract  Background: There are 6 species of venomous snakes in Taiwan. Two of them, Deinagkistrodon acutus (D. acutus) and Daboia siamensis (D. siamensis), can cause significant coagulopathy. However, a significant proportion of patients with snakebites cannot identify the correct snake species after envenomation, which hampers the application of antivenom. Hence, the differential diagnosis between the two snakebites by clinical presentations is important. This study aims to compare their clinical and laboratory features for the purpose of differential diagnosis between the two snakebites.  Methods: We retrospectively reviewed the medical records of patients who arrived at the emergency department due to D. acutus or D. siamensis envenomation, between...

Public health aspects of snakebite care in West Africa: perspectives from Nigeria
Provedor de dados: 80
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...

Snakebite on the hand: lessons from two clinical cases illustrating difficulties of surgical indication
Provedor de dados: 80
Autores: Gras,S; Plantefève,G; Baud,F; Chippaux,JP.
Snakebite is a particularly important health problem in rural areas of tropical regions. A large number of victims survive with permanent physical sequelae due to local tissue necrosis. However, necrosis may be associated with compartment syndrome especially when the bite is on the hands or feet. Herein, we describe two cases reported at a rural district hospital in Central African Republic. The present study suggests that active multidisciplinary management may improve patient prognosis while evidencing how difficult it is to decide on surgical intervention.

Autores: Amin,MR; Mamun,SMH; Rashid,R; Rahman,M; Ghose,A; Sharmin,S; Rahman,MR; Faiz,MA.
Snakebites can present local or systemic envenomation, while neurotoxicity and respiratory paralysis are the main cause of death. The mainstay of management is anti-snake venom (ASV), which is highly effective, but liable to cause severe adverse reactions including anaphylaxis. The types of adverse reaction to polyvalent anti-snake venom have not been previously studied in Bangladesh. In this prospective observational study carried out between 1999 and 2001, in the Snake Bite Study Clinic of Chittagong Medical College Hospital, 35 neurotoxic-snake-bite patients who had received polyvalent anti-snake venom were included while the ones sensitized to different antitoxins and suffering from atopy were excluded. The common neurotoxic features were ptosis...

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...

Snakebites in Turkey: epidemiological and clinical aspects between the years 1995 and 2004
Provedor de dados: 80
Autores: Cesaretli,Y; Ozkan,O.
The venom of poisonous snakes comprises a complex mixture of several proteins with other less significant constituents, resulting in principles capable of changing viable tissues. The hemotoxic factor is the main responsible for necrosis and tissue sloughing. Envenomations are common in rural areas of Turkey caused by snake species that present hepatotoxic venom, which causes local swelling, ecchymosis and alterations in blood profile. The epidemiological and clinical findings of snake envenomations in Turkey were evaluated based on data recorded by the National Poison Information Center (NPIC) between 1995 and 2004, in a total of 550 snakebite cases. The month of peak incidence was June (24.3%) while most incidents occurred in Marmara, Central Anatolia...

Posterior fossa infarct following Viper bite: a paradox
Provedor de dados: 80
Autores: Deepu,D; Hrishikesh,S; Suma,MT; Zoya,V.
Cerebral infarction after a viper bite is relatively uncommon. A combination of factors has been implicated in the pathophysiology of infarct following snakebite. In this case report, the clinical outcome after a posterior circulation infarct and various possibilities that could lead to such a catastrophic event are discussed. The present study stresses the need to keep hydration, blood pressure and central venous pressure optimal in all snakebite patients. Cerebral infarction should be considered a differential diagnosis, in any patient with neurological deterioration following snakebite. Prognosis of such patients with posterior circulation stroke remains poor and decompressive craniectomy has not been found to be helpful.

Presumptive thrombotic thrombocytopenic purpura following a hump-nosed viper (Hypnale hypnale) bite: a case report
Provedor de dados: 80
Autores: Withana,Milinda; Rodrigo,Chaturaka; Gnanathasan,Ariaranee; Gooneratne,Lallindra.
Hump-nosed viper bites are frequent in southern India and Sri Lanka. However, the published literature on this snakebite is limited and its venom composition is not well characterized. In this case, we report a patient with thrombotic thrombocytopenic purpura-like syndrome following envenoming which, to the best of our knowledge, has not been reported in the literature before. A 55-year-old woman from southern Sri Lanka presented to the local hospital 12 hours after a hump-nosed viper (Hypnale hypnale) bite. Five days later, she developed a syndrome that was characteristic of thrombotic thrombocytopenic purpura with fever, thrombocytopenia, microangiopathic hemolysis, renal impairment and neurological dysfunction in the form of confusion and coma. Her...

Toxicity and symptomatic identification of species involved in snakebites in the Indian subcontinent
Provedor de dados: 80
Autores: Kumar,V.; Maheshwari,R.; Verma,H. K.
Snakebites, being the major occupational hazard for farm workers, claim a large number of lives in the Indian subcontinent. During the course of medical management, identification of the biting species is given a low priority, resorting to prescription of polyvalent anti-snake venom. Whereas the World Health Organization (WHO) recommends monospecific anti-snake venom instead of polyvalent anti-snake venom. Thus, it is essential to identify the aggressor species either by a visual inspection or by the symptoms of the victim. Along with the four deadly venomous species (cobra, krait, Russell's viper, and saw-scaled viper), there are a number of other species of medical importance, whose venoms and bites have not been paid much attention. Thus, a...

Numerous plants are used as snakebite antidotes in Brazilian folk medicine, including Casearia sylvestris Swartz, popularly known as guaçatonga. In this study, we examined the action of a hydroalcoholic extract from C. sylvestris on the neuromuscular blockade caused by bothropstoxin-I (BthTX-I), a myotoxin from Bothrops jararacussu venom, in mouse isolated phrenic nerve-diaphragm (PND) preparations. Aqueous (8 and 12 mg/ml, n=4 and 5, respectively) and hydroalcoholic (12 mg/ml, n=12) extracts of the leaves of C. sylvestris caused facilitation in PND preparations followed by partial neuromuscular blockade. BthTX-I (20 µg/ml, n=4) caused 50% paralysis after 65±15 min (mean ± S.E.M). Preincubation (30 min at 37° C) of BthTX-I (20 µg/ml, n=4) with a...

Autores: Kweon,EY; Lee,DW; Ahn,M; Nork,TM; Cho,NC.
Viper venoms act mainly on blood and blood vessels. Reports of ophthalmic manifestations after snakebite include ptosis and ophthalmoplegia. In the current study, we describe a case that developed bilateral retinal and subretinal hemorrhage following snakebite. Bilateral retinal hemorrhage is a rare ocular complication of snake envenomation and has not been reported with fundus photographs in the literature so far.

The WHO strategy for prevention and control of snakebite envenoming: a sub-Saharan Africa plan
Provedor de dados: 80
Autores: Chippaux,Jean-Philippe; Massougbodji,Achille; Habib,Abdulrazaq G.
Abstract Snakebite is a critical public health issue in tropical countries, particularly in Africa, where 20% of snakebites globally occur. In 2017, the WHO added snakebite envenoming to the category A of neglected tropical diseases. In 2019, thanks to broad institutional and international NGO support, including strong mobilization of African experts and governments, WHO launched a strategy for prevention and control of snakebite envenoming with more ambitious goals. In sub-Saharan Africa, accessibility of antivenoms and symptomatic, adjuvant or replacement therapy is a priority. Several antivenoms are available but their evaluation has not been properly carried out and they remain expensive. To date, there are no manufacturers of antivenom in sub-Saharan...
