Scorpionism in Iran

Previously this year two papers on scorpionism in Iran have been published. The most medical important species are Hemiscorpius lepturus (Peters, 1862) (Hemiscorpiidae) and Androctonus crassicauda (Oliver, 1807) (Buthidae), and serious cases of scorpion envenomation including deaths are reported.

Paper 1:
Background: Scorpion sting is a major health problem in Iran. The aim of current study was to measure the incidence rates of scorpion stings, mortality, recovery, and affected age groups. The results of treatment with and without anti venom also were considered in the entire country during 2009.
Methods: All the data were collected from emergency section of different hospitals and then were analyzed by related software. The responsibility of such data collection and surveillance is related to the Department of Violence and Injury, Ministry of Health and Medical Education of Iran.
Results: A total incidence of 59.5/100000 was found for the 12-month period. During the study period the most and the least cases were reported from Khuzestan and Mazandaran Provinces with incidence of 541 and 0 per 100000 respectively. Totally 40220 anti venom vials were used, i.e., the ratio of 91 vial/ 100 affected cases. The stings occur mainly in rural areas (57.7%). Young people with the age group of 15–24 years old were the most victims of stings. The mortality and recovery rates of cases who had received anti venom less than 6 h of stings were calculated as 0.01% and 99.9% respectively.
Conclusion: The high incidence of scorpion stings in Iran especially in Khuzestan suggests the necessity of preventive programmes for decreasing the incidence. Such programmes could start by community educating in the high prevalent areas. In addition prompt and local treatment is particularly important for infants and pre-school children.

Paper 2:
Scorpionism is a major health problem in Khuzestan, included Ramhormoz, south-west of Iran. This descriptive retrospective survey was conducted to give us basic information about scorpionism in this city during 2006-2010. During 2006-2010, a total of 20902 scorpion-stung patients referred to the Rmhormoz health centers. The frequencies of entomo epidemiological and medical parameters were recorded converted to the percentage rank. The results of this study showed that the preventing ways of scorpion stings should be educated among the residents and antivenin of scorpions provided in the health centers of Ramhormoz.
