Association Between Gut Microbiome Composition and Physical Characteristics in Patients with Severe Motor and Intellectual Disabilities: Perspectives from Microbial Diversity.

Background: The human gut environment undergoes substantial changes as a host ages. This investigation centered on the gut microbiome diversity among patients with severe motor and intellectual disabilities (SMID), examining the association between the gut microbiome composition and physical characteristics with varying levels of diversity.

Methods: Fourteen subjects were investigated, with physical and defecation status, blood biochemical test, gut microbiome profiling, and fecal metabolites used to divide the patients into a high-diversity group (HD, eight patients) and a low-diversity group (LD, six patients).

Evaluation of the labrum on postoperative magnetic resonance images: a predictor of acetabular development in developmental dysplasia of the hip.

Introduction: Residual acetabular dysplasia of the hip after open reduction can complicate the treatment of developmental dysplasia of the hip (DDH) due to the potential need for corrective surgery. This retrospective study aimed to determine the predictive factors for acetabular development using postoperative radiographs and magnetic resonance imaging (MRI).

Methods: We retrospectively investigated 74 hips of patients with DDH who underwent open reduction after reaching walking age and were followed up radiologically until skeletal maturity.

Acetabular depth, an early predictive factor of acetabular development: MRI in patients with developmental dysplasia of the hip after open reduction.

Early prediction of future acetabular development is important to determine an additional surgery for developmental dysplasia of the hip (DDH). The purpose of this study was to investigate the predictive factors of acetabular development using MRI. We retrospectively investigated dislocated 40 hips and 34 normal hips in 37 pediatric patients (9 males and 28 females) with DDH who underwent open reduction after walking age.

Idiopathic Chondrolysis of the Hip Treated by Immunosuppressive Therapy and Arthroscopic Intervention.

Idiopathic chondrolysis of the hip (ICH), a very rare disorder of unknown etiology, occurs mainly in female adolescents. Characterized by pain, limp, stiffness and radiological narrowing joint space from the rapid destruction of the articular cartilage, ICH sometimes results in ankyloses. We present the case of a 10-year-old girl diagnosed with ICH based on arthroscopic inspection and synovium biopsy.

Residual Femoral Deformity and Femoroacetabular Impingement after Intertrochanteric Osteotomy for Slipped Capital Femoral Epiphysis.

We retrospectively reviewed 29 hips in which intertrochanteric osteotomies were performed for severe slipped capital femoral epiphyses. Mean age at surgery: 12.6 years.

Scoliosis in Patients with Severe Cerebral Palsy: Three Different Courses in Adolescents.

Patients with cerebral palsy (CP) frequently present with scoliosis; however, the pattern of curve progression is difficult to predict. We aimed to clarify the natural course of the progression of scoliosis and to identify scoliosis predictors. This was a retrospective, single-center, observational study.

Two-directional arthrographic assessment for treating bilateral development dislocation of the hips in children after walking age.

We reviewed the treatment outcome in 14 hips of 7 patients who were diagnosed as having bilateral developmental dislocation of the hip (DDH) after walking age and could be followed up until they were at least 14 years of age. Based on the results of two-directional arthrography of the hip, closed reduction was performed in 2 hips, and open reduction was performed without osteotomy in 12 hips. The final radiographic evaluations were made according to the Kalamchi and MacEwen classification and Severin classification.

Intra-articular loose body caused by avascular necrosis of the femoral head in children.

In children, avascular necrosis of the femoral head occurs easily because of the difference in the domination of blood flow compared with that in adults. Here we report a rare case of a 12-year-old girl who sustained a femoral neck fracture. The femoral head collapsed after open reduction and internal fixation.

Changes in the lateral pillar classification in Perthes' disease.

The purpose of this study was to examine the correlation between the changes in the lateral pillar grades and the factors influencing such changes. We reviewed 102 patients with Perthes' disease. Changes were observed in 32 (31%) hips.

Lateral and posterior pillar grade changes during the treatment of Perthes disease in older patients using skin traction and range of motion exercises.

Introduction: The lateral pillar (LP) grade changes detected during treatment periods have received a lot of attention recently. Lappin et al. reported LP collapses in 92 of 275 (33%) patients during the treatment, but did not provide information for comparing treatment methods and age of onset of the disease.

Role of the limbus in femoral-head deformation in developmental dislocation of the hip: findings of two-directional hip arthrography.

Two-directional arthrographic findings made during conservative treatment of developmental dislocation of the hip were compared with the femoral-head configurations and radiological results obtained from long-term follow-up examinations in this retrospective study. Sixty hips were followed until at least age 14. Arthrography was carried out according to Terazawa's method.
