Introduction: Considering the cost of Anti-Snake Venom (ASV) and irregularity in its supply, there is often a need to curtail doses of ASV, despite guidelines for management of snake bite. During June 2013 to September 2013, when ASV was in short supply, our institutional committee reviewed the overall hospital statistics of snake bite cases as well as scientific literature and formulated a working modified protocol that used low dose of ASV in snake bite cases. Aim: To retrospectively analyse and compare the modified ASV protocol versus conventional ASV protocol with respect to outcome, number of ASV vials required, duration of stay in the hospital/ ICU, and additional supportive interventions needed...

Micrurus snakes, commonly known as coral snakes, are responsible for 0.4% of the snakebites envenomings in Brazil. In this report, we describe a case of envenoming by Micrurus averyi, the black-headed coral snake, recorded in the western Brazilian Amazon. To the best of our knowledge, this is the first published case perpetrated by this species. The major complaint of the patient was an intense local pain and paresthesia. Examination of the bite site revealed edema extending from the left foot up the left leg that was accompanied by erythema involving the foot and distal third of the leg...

Proteins from TCTP/HRF family were identified as venom toxins of spiders from different genus. We have found a TCTP toxin in the venom gland of Loxosceles intermedia, a venomous spider very common in South Brazil. TCTP from L. intermedia, named LiTCTP, was cloned, produced in a heterologous prokaryotic system, and the recombinant toxin was biochemically characterized. Our results point that LiTCTP is involved in the inflammatory events of Loxocelism, the clinical signs triggered after Loxosceles sp. bite, which include intense inflammatory reaction at the bite site followed by local necrosis...

Phospholipase A2-like (PLA2-like) proteins contribute to the development of muscle necrosis in Viperidae snake bites and are not efficiently neutralized by current antivenom treatments. The toxic mechanisms of PLA2-like proteins are devoid of catalytic activity and not yet fully understood, although structural and functional experiments suggest a dimeric assembly and that the C-terminal residues are essential to myotoxicity. Herein, we characterized the functional mechanism of bothropic PLA2-like structures related to global and local measurements using the available models in the Protein Data Bank and normal mode molecular dynamics (NM-MD)...

A 13-year-old female presented with diminution of vision in both eyes for 3 months following snakebite. Best-corrected visual acuities were hand movement in both eyes. Fundoscopy showed vitreous hemorrhage, and B-scan ultrasonography revealed an underlying tractional retinal detachment (TRD) involving the macula in both eyes. Patient underwent 25-gauge pars plana vitrectomy in conjunction with belt buckling, endolaser, and silicone oil tamponade in the left eye. At 6 weeks postoperatively, best-corrected visual acuity of the left eye was noted to be 20/200 with settled TRD and attached retina...

Snake venom serine proteinases are toxins that perturb hemostasis acting on proteins from the blood coagulation cascade, the fibrinolytic or the kallikrein-kinin system. Despite the relevance of these enzymes in envenomations by viper bites, the characterization of the antibody response to these toxins at the molecular level has not been previously addressed. In this work surface-located B cell recognized linear epitopes from a Lachesis stenophrys venom serine proteinase (UniProt accession number Q072L7) were predicted using an artificial neuronal network at the ABCpred server, the corresponding peptides were synthesized and their immunoreactivity was analyzed against a panel of experimental and therapeutic antivenoms...

BACKGROUND: Hump-nosed viper bite is the commonest cause of venomous snakebite in Sri Lanka. Despite initially being considered a moderately venomous snake more recent reports have revealed that it could cause significant systemic envenoming leading to coagulopathy and acute kidney injury. However, myocardial infarction was not reported except for a single case, which occurred immediately after the snakebite. CASE PRESENTATION: A 50-year-old previously healthy Sri Lankan woman had a hump-nosed viper bite with no evidence of systemic envenoming during initial hospital stay...

BACKGROUND: Across the world, many species of nondomesticated animals dwell among humans in metropolitan areas. Rare animal bites pose a dilemma for hand surgeons, as they often result in operative injuries and recalcitrant infections. The authors treated an 85-year-old man who experienced severe cellulitis of the index finger following an opossum bite. This case prompted a systematic review of upper extremity injuries caused by species other than dogs, cats, snakes, and insects. METHODS: The authors conducted a systematic review of PubMed and Scopus databases to identify relevant articles published between 1980 and 2016...

Dawei Han, Bruce A Young
The Calabar burrowing python (Calabaria reinhardtii) has a unique combination of marked thickness of the integumentary layers, a highly organized lamellate arrangement of the dermal collagen bundles, and a reduction in the size of the interscale hinge region of the integument. Biomechanical testing demonstrates that the skin of C. reinhardtii is more resistant to penetration than the skin of other snakes. The laminar arrangement of the collagen bundles provides for penetrative resistance, even while maintaining the flexibility characteristic of snake skin...

Timothy P Jenkins, Andrés Sánchez, Álvaro Segura, Mariángela Vargas, María Herrera, Trenton K Stewart, Guillermo León, José María Gutiérrez
Haemorrhage is a common clinical manifestation in envenomings caused by bites from snakes of the family Viperidae. Therefore, knowing the haemorrhagic potential of venoms and the capacity of antivenoms to neutralise this effect are of paramount relevance in toxinology. The most widely used method for quantifying haemorrhage involves the intradermal injection of venom (or a mixture of venom/antivenom) in mice, and the assessment of the resulting haemorrhagic area in the inner side of the skin. Although this method allows a straightforward assessment of the haemorrhagic activity of a venom, it does not account for haemorrhagic lesions having a similar area but differing in the depth and intensity of haemorrhage...

Antivenom is the most effective method currently available for the treatment of poisonous snake bite. Allergic reactions to antivenom have been reported in the past. Here we shared a case of allergic reactions to antivenom in an old male patient who was bitten twice by the same snake (probably same one) at the same biting site within a month whereas the patient did not show any allergic disorder in the first bitten. Envenomations twice in a short period time by the same kind of snake are very rare. Physician should be alert to the occurrence of allergic reactions in treating this type of patients with antivenom...
