ZOOKEYS

A new scorpion species, Euscorpius lycius sp. n., is described based on specimens collected from Mugla and Antalya Provinces, in southwestern Turkey. It is characterized by a standard trichobothrial pattern (Pv= 8/9, et= 6, em= 4, eb= 4), small size and light brown/reddish coloration. With the description of Euscorpius lycius sp. n., the number of valid species of the genus Euscorpius in Turkey increases to 5

ACTA ZOOLOGICA BULGARICA

The scorpion species Euscorpius italicus (Herbst, 1800) is recorded for first time from Cyprus. This represents a new scorpion family, genus and species record for the country. Besides, this is first insular record from Mediterranean Sea. The characteristic morphological features, zoogeographical remarks and ecological notes on the species are presented in this study

JOURNAL OF ARTHROPOD-BORNE DISEASES

Background: In this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of Hottentotta saulcyi scorpion venom in mice. Methods: Scorpions were collected at night, by using a UV lamp from Mardin Province, Turkey. Venom was obtained from mature H. saulcyi scorpions by electrical stimulation of the telson. The lethality of the venom was determined by i.v. injections using Swiss mice. In vivo effects of the venom were assessed by using the intraperitoneal route (ip) injections into mice (20 +/- 1g) and monitored for 24 h. The protein profiles of the scorpion venom were analyzed by NuPAGE (R) Novex (R) 4-12 % gradient Bis-Tris gel followed by Coomassie blue staining. Results: The lethal assay of the venom was 0.73 mg/kg in mice. We determined the electrophoretic protein pattern of this scorpion venom to be 4, 6, 9, 31, 35, 40, 46 and 69 kDa by SDS-PAGE. Analysis of electrophoresis indicated that H. saulcyi scorpion intoxicated mice exhibited autonomic nervous system symptoms (tachypnea, restlessness, hyperexcitability, convulsions, salivation, lacrimation, weakness). Conclusions: Hottentotta saulcyi scorpion venom includes short-chain neurotoxins and long-chain neurotoxins according to the electrophoretic protein patterns. The stings of H. saulcyi scorpion must be considered of risk for humans in the southeastern region, Turkey

is stung by Leiurus abdullahbayrami

Venom of Leiurus abdullahbayrami (Scorpiones: Buthidae) is an extremely toxic one and it stimulates voltage-gated sodium and potassium channels. In case of a stung by this scorpion; excessive catecholamine release occur and it impairs left ventricle contractility and consequently a heart failure occurs (scorpion sting-related cardiomyopathy). In addition to this cardiac-induced acute pulmonary, edema may occur in severe cases too. An 11-year-old male child who was stung by a scorpion (species: Leiurus abdullahbayrami) consulted to the Emergency Room. Even after 7 h of scorpion envenomation he was confused and having hallucinations. Besides he was dyspneic, tachycardic, hypotensive and got worse in overall situation due to cardiogenic pulmonary edema. These clinical findings are concordant with the Level III scorpion envenomation (major systemic manifestations). Positive inotropic agents, diuretics and antiagregant agents used on supportive therapy in his treatment. After 2 weeks he get recovered and discharged from the pediatric intensive care unit. This research is conducted by thinking emergency physicians should learn that Leiurus abdullahbayrami envenomation can cause scorpion-related cardiomyopathy and acute pulmonary edema especially in children.

A newly described scorpion species, Leiurus abdullahbayrami (Scorpion: Buthidae), and the lethal potency and in vivo effects of its venom

Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identified as L. quinquestriatus in Turkey) was classified as a new Leiurus species. This is the first report conducted on the lethality and biologic effects of L. abdullahbayrami scorpion venom in mice. In this study, the electrophoretic protein pattern of its venom was also determined. Two protein bands with molecular masses of 4 and 6 kDa were more strongly detected than other protein bands in the venom sample. Electrophoresis showed that L. abdullahbayrami scorpion venom possesses both short- and long-chain neurotoxins. The median lethal dose of this venom was found to be 0.19 mg/kg by subcutaneous (SC) injection in mice. Animals experimentally envenomed with L. abdullahbayrami venom exhibited hyperexcitability, agitation, aggressive behavior, squeaking and fighting, tachypnea, weakness, convulsions, and death due to cardiac and respiratory failure. In further studies, the potency of antivenom should be investigated in relation to the scorpion venom. Molecular and pharmacological studies are also required to identify and characterize L. abdullahbayrami scorpion venom

613 cases of splenic rupture without risk factors or previously diagnosed disease: a systematic review

Background Rupture of the spleen in the absence of trauma or previously diagnosed disease is largely ignored in the emergency literature and is often not documented as such in journals from other fields. We have conducted a systematic review of the literature to highlight the surprisingly frequent occurrence of this phenomenon and to document the diversity of diseases that can present in this fashion. Methods Systematic review of English and French language publications catalogued in Pubmed, Embase and CINAHL between 1950 and 2011. Results We found 613 cases of splenic rupture meeting the criteria above, 327 of which occurred as the presenting complaint of an underlying disease and 112 of which occurred following a medical procedure. Rupture appeared to occur spontaneously in histologically normal (but not necessarily normal size) spleens in 35 cases and after minor trauma in 23 cases. Medications were implicated in 47 cases, a splenic or adjacent anatomical abnormality in 31 cases and pregnancy or its complications in 38 cases. The most common associated diseases were infectious (n = 143), haematologic (n = 84) and non-haematologic neoplasms (n = 48). Amyloidosis (n = 24), internal trauma such as cough or vomiting (n = 17) and rheumatologic diseases (n = 10) are less frequently reported. Colonoscopy (n = 87) was the procedure reported most frequently as a cause of rupture. The anatomic abnormalities associated with rupture include splenic cysts (n = 6), infarction (n = 6) and hamartomata (n = 5). Medications associated with rupture include anticoagulants (n = 21), thrombolytics (n = 13) and recombinant G-CSF (n = 10). Other causes or associations reported very infrequently include other endoscopy, pulmonary, cardiac or abdominal surgery, hysterectomy, peliosis, empyema, remote pancreato-renal transplant, thrombosed splenic vein, hemangiomata, pancreatic pseudocysts, splenic artery aneurysm, cholesterol embolism, splenic granuloma, congenital diaphragmatic hernia, rib exostosis, pancreatitis, Gaucher's disease, Wilson's disease, pheochromocytoma, afibrinogenemia and ruptured ectopic pregnancy. Conclusions Emergency physicians should be attuned to the fact that rupture of the spleen can occur in the absence of major trauma or previously diagnosed splenic disease. The occurrence of such a rupture is likely to be the manifesting complaint of an underlying disease. Furthermore, colonoscopy should be more widely documented as a cause of splenic rupture
