بررسی مشخصات بالینی و آزمایشگاهی و پاسخ به درمان در کودکان مبتلا به استئومیلیت حاد

Background: Acute osteomyelitis is one of pediatric emergency which can cause unpleasant complications among them. This is especially accurate if the diagnosis had been delayed or the treatment was inappropriate. There is some misunderstanding in the detection of patients’ hospital files and it’s difficult to detect the diagnostic and treatment malpractice. We performed an investigation of the clinical and paraclinical data in children with acute osteomyelitis. Methods: We performed a retrospective cross-sectional study in pediatric department of Imam Khomeini University Hospital in Tehran, Iran, from April 1997 to March 2010. The hospital records of all neonates and children from 15 days old to 15 years old were investigated. Patients with any defect in records were excluded from the study. A total of 54 children were included in this study. A questionnaire including clinical features, paraclinical findings and treatment response was completed for all subjects by design's executer. Data were analyzed using the software package SPSS version 16 (IBM, Armonk, NY, USA). Results: In general, 35 children were male and 19 children were female. The average of age was 5.89 years. Children were divided into 4 groups based on age (less than 2, 2-7, 7-12 and 12-15 years) that majority of them were less than 2 years old (38.9%). The most common symptom and sign were pain (46.3%) and swelling (88.8%) respectively in this study. The most primary presenting symptoms were pain (46.3%) and swelling (24.1%). The comparison of frequency ranges of fever between children younger than 2 years and children 2-15 years old demonstrated a significant different (14.3% vs 84.8%, respectively) (P= 0.001). Staphylococcus aureus was the most commonly isolated organism (73.5%). Thirty-two patients (59.2%) needed surgical procedures in addition to antibiotic therapy that had successful outcome in all cases. The average of treatment duration with intravenous antibiotic was 28.14±12.84 days. Conclusion: More than half of the children with acute osteomyelitis didn't response to antibiotic therapy and they needed different types of surgeries.
