Recent reports in the lay press have suggested that bites by rattlesnakes in the last several years have been more severe than those in the past. The explanation, often citing physicians, is that rattlesnakes are evolving more toxic venom, perhaps in response to anthropogenic causes. We suggest that other explanations are more parsimonious, including factors dependent on the snake and factors associated with the bite victim's response to envenomation. Although bites could become more severe… Expand
An Analysis of Media-Reported Venomous Snakebites in the United States, 2011-2013.
TLDR
Although bias in snakebite reporting patterns by the media is likely, across the United States "legitimate" bites from unseen snakes appear to be the norm. Expand
Neurological effects of venomous bites and stings: snakes, spiders, and scorpions.
TLDR
Proper management of the envenomed patient, including prompt transport to the hospital, correction of the hemostatic disorder, ventilatory support, and administration of antivenom, significantly reduce the risk of neurological complications which, in turn, reduce the mortality and improve the functional outcome of survivors. Expand
Neurological effects of venomous bites and stings: snakes, spiders, and scorpions.
TLDR
Proper management of the envenomed patient, including prompt transport to the hospital, correction of the hemostatic disorder, ventilatory support, and administration of antivenom, significantly reduce the risk of neurological complications which, in turn, reduce the mortality and improve the functional outcome of survivors.

Case reports of envenomation and venom composition differences between two Arizona populations of the Southwestern Speckled Rattlesnake, Crotalus pyrrhus (Cope, 1867).
TLDR
The Phoenix Mountains patient developed hemorrhagic bullae and tissue damage in his bitten extremity, necessitating the amputation of the distal portion of his middle finger, and venom samples were largely similar but appeared to differ quantitatively for several toxin families between and within populations. Expand
Epidemiology of fatal snakebites in the United States 1989-2018.
TLDR
Rattlesnake envenomations are more likely to be fatal than bites from other species, and intentionally engaging with a venomous snake raises the risk of incurring a fatal bite, as does concurrent alcohol or drug use. Expand
Mojave toxin-type ascending flaccid paralysis after an envenomation by a Southern Pacific Rattlesnake in a dog.
TLDR
This is the first reported case in the veterinary literature of an ascending flaccid paralysis, consistent with Mojave toxin, developing after an envenomation by a Southern Pacific rattlesnake. Expand
Defensive stinging by Parabuthus transvaalicus scorpions: risk assessment and venom metering
TLDR
These scorpions perceive risk and regulate venom expenditure during stinging according to level of threat, providing further support for the venom-metering hypothesis. Expand
Retrospective evaluation of neurotoxic rattlesnake envenomation in dogs and cats: 34 cases (2005-2010).
TLDR
Although the incidence of neurotoxicity secondary to rattlesnake envenomation may be relatively low, patients can have rapid progression of their clinical signs and a higher mortality rate, necessitating timely and appropriate treatment. Expand
Arizona Ridge‐nosed rattlesnake envenomation: Case report of a personal encounter with the official state reptile of Arizona, Crotalus willardi willardi
TLDR
The primary venom effects were local: progression of swelling, tenderness to palpitation, erythema and diminished range of motion, and the patient experienced complete recovery of the venom effects within three days. Expand
Intraspecific venom variation in the medically significant Southern Pacific Rattlesnake (Crotalus oreganus helleri): biodiscovery, clinical and evolutionary implications.
TLDR
This research demonstrates for the first time that variable evolutionary selection pressures sculpt the intraspecific molecular diversity of venom components in C. o. Expand

Neurotoxicity associated with suspected southern Pacific rattlesnake (Crotalus viridis helleri) envenomation.
TLDR
An 18-year-old man was bitten on the hand by a snake he believed to be a Southern Pacific rattlesnake and developed generalized weakness, difficulty breathing, diplopia, dysphagia, and dysphonia, and laboratory evidence of coagulopathy and rhabdomyolysis is exhibited. Expand
Treatment of US Crotalidae Bites
TLDR
Comparing available data on clinical aspects of the two antivenins found that ovine-derived serum-globulin-based ACP (Crofab®) and Antivenin (Crotalidae) Polyvalent (ACP) are comparable in efficacy and incidence of adverse events is compared. Expand
The legitimacy of rattlesnake bites in central Arizona.
TLDR
Medical records of 86 consecutive rattlesnake bite victims cared for at a single medical center were reviewed to determine legitimacy of snake bites, and pet (captive) snakes accounted for almost one third of all illegitimate bites. Expand
Review of Treatment and Complications in 79 Children With Rattlesnake Bite
TLDR
Hospitalization time, complications, and treatment cost were less in patients undergoing fabotherapy and members of groups I and II received polyvalent equine antiviperin serum and fabotherapy, respectively. Expand
FACTORS THAT INFLUENCE VENOM EXPENDITURE IN VIPERIDS AND OTHER SNAKE SPECIES DURING PREDATORY AND DEFENSIVE CONTEXTS
In this paper we review the many factors that can influence the quantity of venom snakes expend when feeding or defending themselves. In addition to data from prior studies, we draw conclusions fromExpand
Does the aggressive use of polyvalent antivenin for rattlesnake bites result in serious acute side effects?
TLDR
The administration of polyvalent Crotalidae antivenin is safe and acute side effects are uncommon, and acute hypersensitivity, when it occurs, consists solely in most cases of urticaria. Expand
Denim clothing reduces venom expenditure by rattlesnakes striking defensively at model human limbs.
TLDR
In this model, denim clothing proved effective at reducing venom injection by both small and large rattlesnakes, and long denim pants as an alternative to shorts may provide a simple, low-cost means of reducing the severity of snakebites. Expand
Association of rattlesnake bite location with severity of clinical manifestations.
TLDR
In minimal to moderate North America crotalid en venomation, patients who sustained bites on distal aspects the digits tended to experience less severe clinical manifestations of envenomation. Expand
Rattlesnake envenomation with neurotoxicity refractory to treatment with crotaline Fab antivenom
TLDR
Two cases of neurotoxicity following rattlesnake envenomation are described in which treatment with crotaline Fab antivenom adequately obtained initial control of local swelling and hematologic effects, but neurotoxic venom effects remained refractory to antivenm therapy. Expand
Pediatric sex group differences in location of snakebite injuries requiring antivenom therapy
TLDR
Male children were more likely than female children to suffer Crotaline snakebites that required antivenom therapy in this population, and significant differences between locations ofSnakebites were found. Expand
