Snakebite is an occupational hazard causing considerable morbidity and mortality worldwide, particularly so in tropical countries like India. An estimated 50,000 Indians die due to venomous snakebite every year, seventy percent of whom are males between the ages of 20 to 50 years. Along with the associated morbidity and mortality, snakebite leads to a significant financial burden on the victim, both by way of hospital bills and labour hours lost. Snakebite is also a cause for considerable psychological stress among survivors...

Venomous snakes-the pinnacle of snake evolution-are characterized by their possession of venom-conducting fangs ranging from grooved phenotypes characterizing multiple lineages of rear-fanged taxa to tubular phenotypes present in elapids, viperids and atractaspidines. Despite extensive research, controversy still exists on the selective pressures involved in fang phenotype diversification. Here, we test the hypothesis that larger fangs and consequently a shift to an anterior position in the maxilla evolved to compensate for the costs of structural changes, i...

Snake bites are common all around the world with a great prevalence in South Asia and the Indian subcontinent. Although they are associated with common complications such as local swelling, bleeding at site of bite, coagulopathy, etc., few rare cardiac complications such as myocardial infarctions and arrhythmias have also been described in literature. The following is a case report of a patient who had a snake bite with a Russell's viper which resulted in atrial fibrillation, which resolved on treatment with anti snake venom...

Fracture is defined as complete or incomplete separation in the continuity of bone Fracture healing is a complex physiological process that involves the coordinated participation of hematopoietic and immune cells within bone marrow. It conjunction with vascular and skeletal cell precursors it also includes mesenchymal stem cells which are recruited from the circulation and the surrounding tissues. It is estimated that 80% of the population in developing countries still rely on the traditional herbal medicines...

Green pit viper is a venomous endemic snake in Sri Lanka. But little is known regarding its envenoming in the country. This study was carried out in order to find out epidemiology and clinical profile of its bites. A series of 17 patients with Sri Lankan Green pit viper (Trimeresurus trigonocephalus) bites was prospectively studied over 4 years. The mean age was 36 ½ years (range 12-61 years) and comprised 14 (82%) males. Except one case, all bites occurred during day time (0600 h-1800 h) due to inadvertent provocation...

While the administration of antivenom to treat hemotoxic snake bite injury remains the gold standard of therapy, we have demonstrated that modifying human fibrinogen with iron and carbon monoxide renders it resistant to fibrinogenolytic snake venom enzymes. In order to translate these findings into a possible biometal-based therapy complementary to antivenom administration, a preclinical model that possesses fibrinogen that closely mimics the human molecule in response to iron and carbon monoxide needed to be identified...

INTRODUCTION: Epidemiologic studies of snakebites in the United States report typical victims to be young men. Little is known regarding other demographics including children and the elderly. The objective of this study was to describe the epidemiology and clinical manifestations of snake bite in elderly patients reported to the ToxIC (Toxicology Investigators Consortium) North American Snakebite Registry (NASBR) Methods: This was a multicenter analysis of a prospectively collected cohort of patients with snakebite reported to the ToxIC NASBR between 1 January 2013 and 31 December 2015...

Daboia palaestinae is the most common venomous snake in Israel and an important cause of envenomations in humans and animals. Although specific antivenom is produced from horses, little documentation exists regarding the characteristics of envenomed horses. This survey was constructed to describe the clinical, hematological and biochemical characteristics of D. palaestinae envenomation in horses, to identify risk factors for fatality and to construct a prognostic snakebite severity scale (SSS) to be used by veterinarians in the field...

Several in vitro investigations have demonstrated that anticoagulant effects of fibrinogenolytic snake venom metalloproteinases have been abrogated in human plasma by modifying fibrinogen with iron (Fe) and carbon monoxide (CO) to prevent catalysis or by directly inhibiting these enzymes with CO. To translate these findings, we chose to assess the rabbit as a model of envenomation with Crotalus atrox venom. It was determined with thrombelastography that 15 times the concentration of venom noted to compromise coagulation in plasma in vitro was required to cause coagulopathy in vivo, likely secondary to venom binding to blood cells and being cleared from the circulation rapidly...

Envenomation by haemotoxic enzymes remains a significant source of human morbidity and mortality worldwide, with administration of long-acting or multiple doses of antivenom first-line therapy. However, coagulopathy can still occur and recur. Of interest, it has been recently demonstrated that direct, isolated exposure of snake venom enzymes with fibrinogenolytic activity to carbon monoxide (CO) abrogates venom-mediated loss of coagulation in human plasma. These observations of CO inhibition of venom fibrinogenolytic activity were subsequently repeated in rabbit whole blood...

BACKGROUND: Snakebite is a major problem affecting the rural poor in many of the poorest countries in the tropics. However, the scale of the socio-economic burden has rarely been studied. We undertook a comprehensive assessment of the burden in Sri Lanka. METHODS: Data from a representative nation-wide community based household survey were used to estimate the number of bites and deaths nationally, and household and out of pocket costs were derived from household questionnaires...

Most of the rare bilateral acute angle closure (AAC) cases are precipitated by systemic factors, such as drug intake, snake bite or general anaesthesia. We present a case of simultaneous bilateral AAC in a middle-aged male, precipitated by the use of medication for flu, containing an alpha-1 adrenergic receptor agonist and an anticholinergic agent. In our case, axial length was shorter, anterior chamber depth was narrower, and the lens was thicker than normal, including the patient within the risk group for AAC...

BACKGROUND: Better knowledge of the epidemiological characteristics of snakebites could help to take measures to improve their management. The incidence and mortality of snakebites in the Americas are most often estimated from medical and scientific literature, which generally lack precision and representativeness. METHODOLOGY/PRINCIPAL FINDINGS: Authors used the notifications of snakebites treated in health centers collected by the Ministries of Health of the American countries to estimate their incidence and mortality...

With increasing trips to tropical areas, as well as a high number of venomous snake holders in the country, the frequency of snake bites is likely to increase. Even if in 50 % of cases, the bites do not lead to clinical envenoming, rapid and effective management is essential to successful treatment, which includes supply with the polyvalent or specific antivenom and recognition of the signs and symptoms justifying its administration. We will deal here mainly with local and tropical snake envenoming that Swiss practitioners could encounter in their offices or the emergency rooms and propose scenarios according to the syndromes...

BACKGROUND: Snake bites are an important public health problem in developing countries with most bites occurring in rural areas. Severe envenomation often occurs in children and following bites to the face. Prompt administration of potent anti-venom remains the mainstay of management. However in Cameroon, the use of anti-venoms is limited by non-availability, high cost (where available) and poor mastery of treatment guidelines. CASE PRESENTATION: We present a 10-year-old muslim Cameroonian child from an enclaved rural area, brought to the hospital 12 h after a snake bite to the face, with signs of severe envenomation...

Most of the studies on the appropriate dose of anti-snake venom (ASV) are from tertiary hospitals and the guidelines are unclear. Our observational study compared the outcomes of two prevalent treatment regimes for haematotoxic snake bite in a secondary care hospital in South India. The time to normalisation of whole blood clotting time, mortality and complications were not different between the groups. The average dose of ASV required in the low and high dose groups were 106 mL and 246 mL, respectively...
