Crotaline and elapid snakebites are reported all over the world as well as in the Middle East and other countries around this region. However, data regarding snakebites and their treatment in Qatar are limited. &is review paper is going to investigate the presentation and treatment of snakebite in Qatar. A good assessment helps to decide on the management of the snakebites envenomation. Antivenom and conservative management are the mainstays of treatment for crotaline snakebite. Point-of-care ultrasound (POCUS) has been suggested to do early diagnosis and treatment of soft tissue problems, such as edema and compartment syndrome, after a snakebite. &e supporting data are not sufficient regarding the efficiency of POCUS in diagnosing the extent and severity of tissue involvement and its ultimate effect on the outcome. -
An in Vivo Examination of the Differences Between Rapid
www.nature.com/scientificreports OPEN An in vivo examination of the diferences between rapid cardiovascular collapse and prolonged hypotension induced by snake venom Rahini Kakumanu1, Barbara K. Kemp-Harper1, Anjana Silva 1,2, Sanjaya Kuruppu3, Geofrey K. Isbister 1,4 & Wayne C. Hodgson1* We investigated the cardiovascular efects of venoms from seven medically important species of snakes: Australian Eastern Brown snake (Pseudonaja textilis), Sri Lankan Russell’s viper (Daboia russelii), Javanese Russell’s viper (D. siamensis), Gaboon viper (Bitis gabonica), Uracoan rattlesnake (Crotalus vegrandis), Carpet viper (Echis ocellatus) and Puf adder (Bitis arietans), and identifed two distinct patterns of efects: i.e. rapid cardiovascular collapse and prolonged hypotension. P. textilis (5 µg/kg, i.v.) and E. ocellatus (50 µg/kg, i.v.) venoms induced rapid (i.e. within 2 min) cardiovascular collapse in anaesthetised rats. P. textilis (20 mg/kg, i.m.) caused collapse within 10 min. D. russelii (100 µg/kg, i.v.) and D. siamensis (100 µg/kg, i.v.) venoms caused ‘prolonged hypotension’, characterised by a persistent decrease in blood pressure with recovery. D. russelii venom (50 mg/kg and 100 mg/kg, i.m.) also caused prolonged hypotension. A priming dose of P. textilis venom (2 µg/kg, i.v.) prevented collapse by E. ocellatus venom (50 µg/kg, i.v.), but had no signifcant efect on subsequent addition of D. russelii venom (1 mg/kg, i.v). Two priming doses (1 µg/kg, i.v.) of E. ocellatus venom prevented collapse by E. ocellatus venom (50 µg/kg, i.v.). B. gabonica, C. vegrandis and B. -

(1) (1) Research Center, Armed Forces Hospital, Riyadh, Saudi Arabia. ABSTRACT: Inflammatory response induced by the venom of the Arabian sand viper Cerastes gasperettii was studied by measuring rat hind-paw edema. Cerastes gasperettii venom (CgV, 3.75-240 µg/paw), heated for 30s at 97°C, caused a marked dose and time-dependent edema in rat paw. Response was maximal 2h after venom administration and ceased within 24h. Heated CgV was routinely used in our experiments at the dose of 120 µg/paw. Among all the drugs and antivenoms tested, cyproheptadine and 5-nitroindazole were the most effective in inhibiting edema formation. Aprotinin, mepyramine, dexamethasone, diclofenac, dipyridamole, Nω- nitro-L-arginine, quinacrine, and nordihydroguaiaretic acid showed statistically (p<0.001) significant inhibitory effect, but with variations in their inhibition degree. Equine polyspecific and rabbit monospecific antivenoms significantly (p<0.001) reduced edema when locally administered (subplantar) but were ineffective when intravenously injected. We can conclude that the principal inflammatory mediators were serotonin, histamine, adenosine transport factors, phosphodiesterase (PDE), cyclooxygenase, lipoxygenase and phospholipase A2 (PLA2), in addition to other prostaglandins and cytokines.

Classic Versus Metabarcoding Approaches for the Diet Study of a Remote Island Endemic Gecko
Questioning the proverb `more haste, less speed': classic versus metabarcoding approaches for the diet study of a remote island endemic gecko Vanessa Gil1,*, Catarina J. Pinho2,3,*, Carlos A.S.

ABSTRACT Dietary studies can reveal valuable information on how species exploit their habitats and are of particular importance for insular endemics conservation as these species present higher risk of extinction. Reptiles are often neglected in island systems, principally the ones inhabiting remote areas, therefore little is known on their ecological networks. The Selvagens gecko Tarentola (boettgeri) bischoffi, endemic to the remote and integral reserve of Selvagens Archipelago, is classified as Vulnerable by the Portuguese Red Data Book. Little is known about this gecko's ecology and dietary habits, but it is assumed to be exclusively insectivorous. The diet of the continental Tarentola species was already studied using classical methods. Only two studies have used next-generation sequencing (NGS) techniques for this genus thus far, and very few NGS studies have been employed for reptiles in general. Considering the lack of information on its diet Submitted 10 April 2019 and the conservation interest of the Selvagens gecko, we used morphological and Accepted 22 October 2019 Published 2 January 2020 DNA metabarcoding approaches to characterize its diet. -

Management of snakebite victims Ayinbuomwan et al. Management of snakebite victims using low dose antisnake venom in a tertiary hospital in Southern Nigeria: A 5-year Retrospective study *Ayinbuomwan A.S.1,2, Opadeyi A.O.1,2, and Isah A.O.1,2 Abstract Objective: Antisnake venom (ASV) is a specific antidote for the management of snake bite envenomations. This study profiled the treatment and outcome of adult snake bite victims managed using low dose antisnake venom. Methods: This was a 5-year retrospective study that involved all adult patients who presented in University of Benin Teaching Hospital, Benin City, Nigeria, with a history of snake bite. Information obtained were demographic characteristics, clinical features, and administered treatment per established. All patients with a diagnosis of snake bite envenomation were administered ASV. Results: Sixty patients were seen during the study period, 35(58.3%) males, 25(41.7%) females with a mean age was 34.7±13.3. The mean time from bite to presentation was 14.67±14.05 hours with range of 1- 48 hours. Twenty patients (33.3%) had snake bite envenomations, of these eleven (57.9%) were managed and discharged after administration of 30 to 40 mls of polyvalent ASV. The mean dose of PASV used was 3.9 ± 2.0 vials. The most encountered clinical indication for ASV administration was progressive painful swelling. No death was recorded throughout this period studied. Conclusion: Adoption of the low dose regimen in the management of snake bite envenomations may be as effective as the traditional high dose regimen. -
Checklist of Amphibians and Reptiles of Morocco: a Taxonomic Update and Standard Arabic Names
Herpetology Notes, volume 14: 1-14 (2021) (published online on 08 January 2021) Checklist of amphibians and reptiles of Morocco: A taxonomic update and standard Arabic names Abdellah Bouazza1,*, El Hassan El Mouden2, and Abdeslam Rihane3,4 Abstract. Morocco has one of the highest levels of biodiversity and endemism in the Western Palaearctic, which is mainly attributable to the country’s complex topographic and climatic patterns that favoured allopatric speciation. Taxonomic studies of Moroccan amphibians and reptiles have increased noticeably during the last few decades, including the recognition of new species and the revision of other taxa. In this study, we provide a taxonomically updated checklist and notes on nomenclatural changes based on studies published before April 2020. The updated checklist includes 130 extant species (i.e., 14 amphibians and 116 reptiles, including six sea turtles), increasing considerably the number of species compared to previous recent assessments. Arabic names of the species are also provided as a response to the demands of many Moroccan naturalists. Keywords. North Africa, Morocco, Herpetofauna, Species list, Nomenclature Introduction mya) led to a major faunal exchange (e.g., Blain et al., 2013; Mendes et al., 2017) and the climatic events that Morocco has one of the most varied herpetofauna occurred since Miocene and during Plio-Pleistocene in the Western Palearctic and the highest diversities (i.e., shift from tropical to arid environments) promoted of endemism and European relict species among allopatric speciation (e.g., Escoriza et al., 2006; Salvi North African reptiles (Bons and Geniez, 1996; et al., 2018).
