The aim of the present study was to assess the success of treatment of septic arthritis of the hip by repeated aspirations and to identify predictive factors for failure.

Compartment syndrome because of acute hemorrhagic edema of infancy: a case report and literature review.

Unlabelled: Acute hemorrhagic edema of infancy (AHEI) is a benign, self-limiting vasculitis that usually resolves completely without any sequelae or a need for active therapy. To our knowledge, compartment syndrome because of AHEI has not been reported. Chart data for a single case were reviewed and reported in a retrospective study.

The radial nuclear positioning of genes correlates with features of megabase-sized chromatin domains.

A nonrandom radial nuclear organization of genes has been well documented. This study provides further evidence that radial positioning depends on features of corresponding ∼1 Mbp chromatin domains (CDs), which represent the basic units of higher-order chromatin organization. We performed a quantitative three-dimensional analysis of the radial nuclear organization of three genes located on chromosome 1 in a DG75 Burkitt lymphoma-derived cell line.

Fractures and refractures after femoral locking compression plate fixation in children and adolescents.

Background: Locking compression plates (LCPs) are being increasingly utilized in fixation of fractures and osteotomies in the pediatric population. However, plate insertion or removal may pose a risk of femoral fractures or refractures. The goal of this study was to analyze failure patterns associated with LCPs and identify possible contributing factors.

Short-term after-effect of forearm cast removal in children.

Purpose: To investigate the sensation in the hand after forearm cast removal in children.

Methods: The study group included 33 consecutive children who were treated nonoperatively for a forearm fracture at our center over a 1-year period. The children were asked to report any sensation in the ipsilateral hand after cast removal, and the findings were analyzed against background and fracture-related data.

Chronic osteomyelitis in children: treatment by intramedullary reaming and antibiotic-impregnated cement rods.

Background: Chronic osteomyelitis (CO) is rarely encountered in developed countries and is especially rare in children and adolescents. However, on occurrence, it can pose a difficult therapeutic challenge necessitating a combination of aggressive surgical treatment and prolonged antibiotic administration.

Methods: Four patients were treated for CO in the Pediatric Orthopaedic Unit at Schneider Children's Medical Center between June 2005 and December 2006 and were reviewed retrospectively.

Intraoperative C-arm radiation affecting factors and reduction by an intervention program.

Background: The increase in the utilization of fluoroscopy during surgical procedures carries with it an inherent increase in the exposure of both patients and surgical staff to ionizing radiation. The purpose of this study was to examine the ability to reduce radiation doses by the implementation of an intervention program targeted at the staff operating the fluoroscopy machinery and attempting to make a behavioral change in its utilization.

Methods: (1) Fluoroscopy technique was optimized after a series of simulation fluoroscopies.

Reference accuracy in peer-reviewed pediatric orthopaedic literature.

Background: Reference accuracy of articles published in the biomedical literature is determined by the presence of citation and quotation errors. A recent review demonstrated that the median citation error rate per biomedical journal was 39%, and the median quotation error rate per journal was 20%. Reference accuracy in pediatric orthopaedic articles has not been previously reported, to our knowledge.

Corrective lower limb osteotomies in children using temporary external fixation and percutaneous locking plates.

Background: We describe a new method for corrective osteotomy and the fixation of lower limb deformities in children.

Methods: Following osteotomy, the desired position is obtained and temporarily stabilized using an external fixator. Definitive fixation is performed with a plate and locking screws inserted percutaneously under fluoroscopic guidance.

Children's daily living activities during immobilization of upper-limb fractures with an above- or below-elbow cast.

Background: The purpose of this prospective study was to assess the impact of cast immobilization on the activities of daily living in children with fractured upper limbs.

Methods: Using the Activities Scale for Kids (ASK), 52 consecutive children (17 girls, 35 boys), aged 5-15 years (mean, 9 years), with upper limb fractures treated by means of above- or below-elbow casts were assessed. The files were reviewed for background and fracture-related data.

Treatment of severe early onset Blount's disease by an intra-articular and a metaphyseal osteotomy using the Taylor Spatial Frame.

Purpose: Severe Blount's disease results in a multiplanar deformity of the lower limb. The mechanical axis is disrupted, there is a rotational deformity, and also shortening of the limb. A depression of the medial tibial plateau causes joint incongruity and instability.

Long-term results of proximal femoral osteotomy in Legg-Calvé-Perthes disease.

Background: Legg-Calvé-Perthes disease is a childhood hip disorder that may result in a deformed and poorly functioning hip. The purpose of this study was to evaluate the correlation between hip deformity at skeletal maturity and degenerative osteoarthritis and to present the long-term results of proximal femoral varus derotational osteotomy in Legg-Calvé-Perthes disease.

Methods: We analyzed the results of 40 patients (43 hips), who underwent proximal femoral varus derotational osteotomy for Legg-Calvé-Perthes disease in our institution between 1959 and 1983.

Correction of lower limb deformities in children with renal osteodystrophy by the Ilizarov method.

Background: Children with renal osteodystrophy (ROD) may develop severe angular deformities of the limbs. Various methods, both medical and surgical, have been described for correction of these deformities, but a literature search showed only 1 child previously treated by the Ilizarov method. The purpose of this study was to characterize the deformities found in our group of patients and to describe our experience in treating these patients with the Ilizarov method.

BAC TransgeneOmics: a high-throughput method for exploration of protein function in mammals.

The interpretation of genome sequences requires reliable and standardized methods to assess protein function at high throughput. Here we describe a fast and reliable pipeline to study protein function in mammalian cells based on protein tagging in bacterial artificial chromosomes (BACs). The large size of the BAC transgenes ensures the presence of most, if not all, regulatory elements and results in expression that closely matches that of the endogenous gene.

Botulinum toxin for the treatment of spasticity in children: attainment of treatment goals.

Forty patients (mean age 5 years) with a spastic disorder treated by botulinum injections (53 sessions) were evaluated for functional outcome in terms of achievement of their individual predetermined goals of treatment, rated on a modified Goal Attainment Scale from 1 (worsening function) to 4 (improved gross motor function). At the 2-week follow-up, 40% had a score of 1, 33% a score of 2, and 13% a score of 3; 12% showed no functional change. Botulinum treatments failed to significantly improve the gross motor function in this patient group.
