Pattern of injury in Shiraz / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>Injury is a major neglected health problem in developing countries. The first step in dealing with injury problem is to identify the injury patterns and characteristics. Therefore, we aimed to demonstrate the current status of trauma admissions to hospitals in Shiraz, as a major city of Iran.</p><p><b>METHODS</b>A hospital-based study was conducted in 2002. All injured patients admitted during 6 months in emergency departments of two general hospitals of Shiraz, Nemazi and Chamran were included.</p><p><b>RESULTS</b>A total of 1,765 injured patients were registered during the study period, with mean age of 33 years. Manual workers were the most vulnerable group among occupational categories. Inner-city roads were the most common place of injury and traffic accident was the major cause of injury. Overally, falling injury was the second common cause of injury in males and the first cause in females (especially at the age of over 60).</p><p><b>CONCLUSION</b>As other studies conducted in our society, traffic accidents are the major cause of morbidity and mortality and this can emphasize on the obligation to take legislative action in the field of driving and road safety, directing resources and educating the public and raising the awareness of the community in prevention of this iceberg-like problem.</p>

[Detection of RET proto-oncogene Cys634Arg mutation, the cause of medullary thyroid carcinoma, in an Iranian child]

Medullary Thyroid Carcinoma [MTC] is hereditary in 25% of cases, and occurs primarily in an autosomal dominant manner. Thus, siblings and offspring of a patient diagnosed with a germline mutation are at a 50% risk for carrying the same mutation. Germline mutations of RET proto-oncogene is the known cause of almost all hereditary MTCs. Mutation analysis of RET is necessary for all apparently sporadic MTC patients. Cases Presentation: In this study, three siblings diagnosed with MTC in a family were analyzed for RET mutations. The result of direct DNA sequencing showed Cys634Arg point mutation in all 3 of them. Screening of their offspring and 4th sibling resulted in identification of a 3-year-old boy as a mutation carrier. According to general consensus, he is at second risk level, which qualifies him for prophylactic total thyroidectomy. Molecular analysis of RET proto-oncogene should be done in a routine manner to differentiate hereditary MTC patients from sporadic ones. In case of finding a germline mutation, all siblings and offspring of the mutation carrier should be screened and asymptomatic carriers referred to total prophylactic thyroidectomy
