#1
Dan Quan, Kenneth Zurcher
BACKGROUND: Cardiotoxicity is a documented complication of Crotalinae envenomation. Reported cardiac complications following snake envenomation have included acute myocardial infarction, electrocardiogram abnormalities and arrhythmias. Few reports exist describing arrhythmia induced by viper envenomation and to our knowledge none describe arrhythmia induced by Crotalinae envenomation. This report concerns the first known case of atrial fibrillation precipitated by rattlesnake bite. CASE PRESENTATION: A 73-year-old Caucasian man with a past medical history of hypertension, hyperlipidemia, type 1 diabetes mellitus, and a baseline first-degree atrioventricular block presented to the emergency department following a rattlesnake bite to his left lower leg...

Pediatric acute compartment syndrome (PACS) is a clinical entity that must be carefully differentiated from the adult version (ie, acute compartment syndrome). Healthcare providers must understand the variable etiologies of PACS, of which trauma is the most common but can also include vascular insult, infection, surgical positioning, neonatal phenomena, overexertion, and snake and insect bites. In addition to the unique etiologies of PACS, providers must also recognize the different signs and symptoms of PACS...

The nature of addiction depends on various factors. The tendency to have already used several addictive substances and to seek high sensation experiences as a result of specific personality traits may lead to extreme and peculiar forms of addictions. Even belonging to specific social and cultural background may lead to such forms of addiction such as intentional snake bite and willful envenomation. In this article, we have discussed the peculiarities and practical insight of such addiction to snake venom. The possible molecular mechanism behind such venom-mediated reinforcement has also been highlighted...

We report acute tetraplegia caused by rat bite fever in a 59-year old man (snake keeper) and transmission of Streptobacillus moniliformis. We found an identical characteristic bacterial pattern in rat and human samples, which validated genotyping-based evidence for infection with the same strain, and identified diagnostic difficulties concerning infection with this microorganism.

Bothrops atrox snakes are the leading cause of snake bites in Northern Brazil. The venom of this snake is not included in the antigen pool used to obtain the Bothrops antivenom. There are discrepancies in reports on the effectiveness of this antivenom to treat victims bitten by B. atrox snakes. However, these studies were performed using a pre-incubation of the venom with the antivenom and, thus, did not simulate a true case of envenomation treatment. In addition, the local lesions induced by Bothrops venoms are not well resolved by antivenom therapy...

Dilated nonreacting pupils are routinely taken as a sign of irreversible brain damage. Alpha-receptor stimulation (scorpion sting) and presynaptic acetylcholine receptor blocker (krait bite) may result in dilation of pupils without involvement of the brain. This study was aimed to clinically evaluate the response of pupils in scorpion sting and krait bite. Victims of scorpion sting and krait bite were chosen from Raigad district. Scorpion sting and krait bite cases were admitted to hospital and were clinically evaluated in detail regarding neurological manifestations...

BACKGROUND: Snakes of the genus Bothrops, popularly known as pit vipers, are responsible for most cases of snakebite in Brazil. Within this genus, Bothrops jararacussu and B. jararaca deserve special attention due to the severity of their bites and for inhabiting densely populated areas. Regarding the treatment of snakebites by Bothrops jararacussu, questions have been raised about the effectiveness of the specific bothropic antivenom in neutralizing myotoxic effects; however, there are no accurate data for humans...

Venom variability is commonly reported for venomous snakes including Bothrops atrox. Here, we compared the composition of venoms from B. atrox snakes collected at Amazonian conserved habitats (terra-firme upland forest and várzea) and human modified areas (pasture and degraded areas). Venom samples were submitted to shotgun proteomic analysis as a whole or compared after fractionation by reversed-phase chromatography. Whole venom proteomes revealed a similar composition among the venoms with predominance of SVMPs, CTLs, and SVSPs and intermediate amounts of PLA2s and LAAOs...

REVIEW
Karl Egil Malterud
The ethnopharmacology, chemistry and pharmacology of four Malian medicinal plants, Biophytum umbraculum, Burkea africana, Lannea velutina and Terminalia macroptera are reviewed. These plants are used by traditional healers against numerous ailments: malaria, gastrointestinal diseases, wounds, sexually transmitted diseases, insect bites and snake bites, etc. The scientific evidence for these uses is, however, limited. From the chemical and pharmacological evidence presented here, it seems possible that the use in traditional medicine of these plants may have a rational basis, although more clinical studies are needed...

Snake bite is an important health hazard in tropics. Snake envenomation in pregnancy may cause fetal death and maternal mortality or morbidity. However, little is known about the toxic effects and optimal management during pregnancy after snake envenomation because of the rarity of cases. Herein, we report a case of a pregnant woman who was successfully treated for snake bite-induced acute kidney injury during the third trimester. She was treated with equine-derived polyvalent anti-snake venom without development of any adverse effects, hemodialysis, and supportive therapy...
