Limb length discrepancy has been observed in children with hemiplegic cerebral palsy (HCP). However, the difference of bone age and limb lengths have been a controversial issue. The purpose of this study was to analyze the bone age and the upper extremity segmental lengths between affected and naffected in HCP patients.Seventy-eight patients (39 boys and 39 girls; mean age 71.3±28.1 months). Fourty-five children were right and 33 were left hemiplegi...

Introduction: It has been reported that low bone mass is common in patients with pulmonary disorders such as chronic obstructive pulmonary disease. However, in healthy non-smoking women, the relationship between bone mass and pulmonary function has yet to be clarified. The object of this study was to determine whether pulmonary function is related to BMD in healthy non-smoking women based on menopausal status.Methods: This study was a cross-sectional stu...

Sphingosine-1-phosphate (S1P) is a significant regulator of bone metabolism. Recently, we found that a high plasma S1P level is associated with low bone mineral density (BMD), high levels of bone resorption markers, and a high risk of prevalent vertebral fracture in postmenopausal women. We investigated the possibility that S1P is a predictor of incident fracture. A total of 263 postmenopausal women participated in this longitudinal study and received follow-up for a mean dura...

The pediatric osteogenesis imperfecta (OI) team at our university hospital was established in 1991. The multi- and inter-disciplinary team consists of: pediatric neurologist, nurse, nursing assistant, physiotherapist, occupational therapist, orthopedic surgeon, orthotist, radiologist, dentist and geneticist. We also have a close collaboration with other specialists.Our assignment is high qualified diagnostics, functional assessments and also individualiz...

The objective of our study is to determine whether GNAS expression correlates with pathognomonic signs by analyzing mutations, methylation status, and G-protein α subunit (Gsα) expression of GNAS (guanine nucleotide binding protein/α stimulating) gene in Ewing Sarcoma (ES).Formalin-fixed paraffin-embedded (FFPE) tissue samples from 77 patients with primary ES were obtained in Korea, Argentina, and Brazil, and w...

A osteoporotic fracture has become a global health issue that causes tremendous impact on mortality as well as heavy socioeconomic burden. Previous studies suggested that vitamin D may prevent fractures by improving muscle mass as well as via increasing bone density directly. The purpose of the study is to determine that the influence of vitamin D on bone mineral density depends on its effects on muscle mass.We analyzed the data from Korean National Heal...

Objective: The aim of this study was to assess the association between bone mineral density (BMD) and coronary atherosclerosis in healthy postmenopausal women.Methods: We performed a retrospective review of 252 postmenopausal women who visited the health promotion center for a routine checkup, after excluding participants who had factors affecting BMD and coronary artery disease. BMD of the lumbar spine and proximal femur was evaluated by dual-energy X-r...

Objective: The aim of this study was to assess the relationship between renal function (estimated glomerular filtration rate (eGFR) using Cockcroft–Gault (CG) equation and modification of diet in renal disease (MDRD), respectively), bone mineral density (BMD) and both arterial stiffness in Korean postmenopausal women.Materials and methods: From January 2008 until December 2010, among the person who got medical examinations including bone densitometr...

The receptor activator of NF-kB (RANK) and ITAM-containing adaptors have been identified as essential factors involved in osteoclast formation and bone remodeling, but their mechanisms and interacting factors have not yet been fully identified. Here we report that early estrogen-induced gene 1 (EEIG1), a novel RANK ligand (RANKL)-inducible protein, physically interacts with RANK and further associates with Gab2, PLCg2, and Tec/Btk kinases by RANKL stimulation. Overexpression o...

Tannerella forsythia is a gram-negative, anaerobic, asaccharolytic, fusiform bacterium. The presence of the bacterium is associated with various forms of periodontal disease, including gingivitis, chronic and aggressive periodontitis. The expression of GroEL, a bacterial heat shock protein, increases in stressful conditions such as infection. GroEL is a moonlighting protein that has multiple functions. The aim of this study was to evaluate the effect of T. forsyth...
