Hooman Hashemian Department of Pediatrics, School of Medicine, Guilan University of Medical Sciences, Guilan, Iran. 2015 09 28 To determine the rate of different types of arthritis in children. We prepared a retrospective descriptive study and included the whole 100 cases of arthritis referred to 17-Shahrivar Hospital, Rasht, Guilan during a 3 years period. Using their medical files, data including age, sex, season of admission, history of trauma, signs and symptoms, lab findings and duration of hospitalization were collected. SPSS 13.0 (statistical software) applied for statistical analysis. The most common age of involvement ranged 6-9 years. Septic arthritis, brucellosis, and rheumatoid fever were the most frequent causes of arthritis in our study. Fever and restricted range of motion had the highest rate among different signs and symptoms. Lab data demonstrated leukocytosis, positive CRP, and increased ESR among 74, 79.5, and 73 percent of our patients, respectively. According to the high prevalence of septic arthritis and the arthritis due to brucellosis and rheumatoid fever, it seems that mentioned diseases are still major problems in the issue of hygiene management. https://acta.tums.ac.ir/index.php/acta/article/view/3539 https://acta.tums.ac.ir/index.php/acta/article/download/3539/3515
