They induce morbidity and rarely mortality. We aimed to investigate clinical, electrocardiographic and para-clinical changes in patients with this bite. Methods: All consecutive patients admitted with suspected spider bites between September 2005 and September 2006 were studied prospectively. Results: Spider bites accounted for 56 cases (0.5% of all poisoning, 21% of all admitted envenomated). The patients\u2019 mean (SD) age was 32 (16) years. The most common findings were pain (90%) mainly in their back (45%), stomach (35%), lower limbs (33%), upper limbs (19%) and chest (14%). Other clinical findings included were sweating (55%), chills (29%), dyspnea (25%), flushing (14%), spasm (12%), headache (12%), nausea (12%) and vertigo (12%). On electrocardiograph (ECG); ST segments were depressed in 25% of cases in at least two of the pre-cordial leads. Laboratory findings were in normal ranges. All the patients recovered following supportive and symptomatic treatment (no anti-toxin available in Iran), with a mean hospitalization period of 1.9 (1.3) days. Conclusions: Spider (L. Tredecimguttatus) bite is relatively common in Mashhad, which induces latrodectism with relatively different findings and cardiac toxicity. ECG monitoring should be considered, particularly when specific anti-toxin is not available.<\/jats:p>","DOI":"10.1177\/0960327109350668","type":"journal-article","created":{"date-parts":[[2009,10,7]],"date-time":"2009-10-07T20:44:52Z","timestamp":1254948292000},"page":"697-702","source":"Crossref","is-referenced-by-count":11,"title":["Spider bite (latrodectism) in Mashhad, Iran"],"prefix":"10.1177","volume":"28","author":[{"given":"R.","family":"Afshari","sequence":"first","affiliation":[{"name":"Medical Toxicology Research Centre, Mashhad University of Medical Sciences, Mashhad, Iran,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Khadem-Rezaiyan","sequence":"additional","affiliation":[{"name":"Medical Toxicology Research Centre, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Balali-Mood","sequence":"additional","affiliation":[{"name":"Medical Toxicology Research Centre, Mashhad University of Medical Sciences, Mashhad, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,10,7]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/j.toxicon.2004.02.002"},{"key":"atypb2","volume-title":"Descriptive epidemiology of intoxication in Mashhad, Iran 56111","author":"Afshari R.","year":"2001"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1081\/CLT-200042550"},{"key":"atypb4","volume-title":"Proceeding of Asian Pacific Association of Medical Toxicologists, 5th International Congress (APAMT-V)","author":"Afshari R."},{"key":"atypb5","doi-asserted-by":"crossref","first-page":"371","DOI":"10.1080\/15563650701502691","volume":"45","author":"Afshari R.","year":"2007","journal-title":"Clin Toxicol"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1053\/j.ctsap.2006.10.003"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1681.2002.03741.x"},{"key":"atypb8","first-page":"437","volume":"131","author":"Schenone H.","year":"2003","journal-title":"Rev Med Chil"},{"key":"atypb9","first-page":"63","volume":"17","author":"Maretic Z.","year":"1966","journal-title":"Bull Int Yugosl Acad Sci Arts"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326-5377.1983.tb122654.x"},{"key":"atypb11","unstructured":"White J.
