Acetabular dysplasia is a well-known cause of early osteoarthritis of hip which may appear at any time (perinatal, breast-feeding and childhood). The aim of this study was to evaluate the clinical and radiographic outcomes of children with de-velopmental dysplasia of hip (DDH) after undergoing open reduction, capsulorrhaphy and Pemberton osteotomy procedures.
This study prospectively conducted on 13 patients with DDH who attended to Razi Hospital at Ahvaz Jundishapur University of Medical Sciences at Ahvaz, Iran, from April 2012 to March 2015. Inclusion criteria were children with age range of 18 months to 8 years and acetabular index≥ 40 degree. Exclusion criteria were the age less than 18 months or above 8 years, connective tissue diseases, secondary dislocation due to previous infection, and acetabular dysplasia with specific syndrome. All patients were evaluated before surgery and at least one year after surgery in terms of clinical evaluations, dislocation or subluxation of hip, congruity of hip and radiological out-comes according to grading systems of McKay, Tonnis grading system, Severin classi-fication and acetabular index, respectively. All patients underwent open reduction, capsulorrhaphy, and Pemberton’s osteotomy in single-stage surgery and if necessary femoral shortening was performed.
Ten patients (12 hips) were evaluated. Of those, 4 patients (40%) had right hip involvement. The mean age score was 38.92±12.37 months (range: 24-65 months). Acetabular index showed significant reduction after surgery in compare to before sur-gery (P= 0.002). According to Tonnis grading, 91.6% of cases were in I-II classes. Moreover, 66.6% of cases at clinical examinations of McKay criteria had excellent and good results after surgery. According to Severin radiographic findings criteria, 83.2% of cases were in I-III classes after surgery. There was statistically significant improvement in patients according to different grading systems.
In conclusion, Pemberton osteotomy could be an effective procedure and also in conjunction with other surgical procedures for the treatment of patients with DDH who presented in higher age and late.

Background and Acute bacterial sinusitis is a very common disease among children. Empirical therapy for acute bacterial sinusitis often includes a 10-14-day period of β-lactamase. Azithromycin, a sustained high tissue level macrolide, due to its pharmacokinetic profile can be used once daily in a shorter treatment course of 3 to 5 days. This study aimed to compare azithromycin and common β-lactamases in treatment of acute bacterial sinusitis. In this randomized clinical trial study, the population consisted of children aged 1 month to 14 years, referred to a tertiary referral hospital from March to July 2011 with the diagnosis of acute bacterial sinusitis. Patients were divided into three groups randomly based on computer and azithromycin; amoxicillin and amoxicillin/clavulanic acid (co-amoxiclav) were prescribed to the group I, II and III, respectively. Signs and symptoms at the days of 2 to 4 and 10 to 14 were evaluated and the collected data were recorded. 155 patients were enrolled with the mean age of 23.23 ± 3.20 months. The response rate was more significant in the group receiving azithromycin compared to other groups (P = 0.0130 and P = 0.0001). On the other hand, the response rate between the two groups receiving amoxicillin and amoxicillin/ clavulanic acid was not significantly different (P = 0.1210). According to this study, further studies need to carry out in order to evaluate azithromycin as a first-line empiric therapy in sinusitis.
