A four-year-old boy presented with a solitary bone cyst in the odontoid process and body of the axis. Plain radiographs showed a radiolucent lesion with extreme thinning of the cortex and MRI demonstrated a high signal intensity in the interlesional matrix. The cystic component extended into the body of the axis through a defect in the epiphyseal plate. At operation, the cavity of the cyst was ...

Progression of slipped capital femoral epiphysis following in situ screw fixation typically occurs through loosening of the screw in the metaphysis. Epiphyseal migration off the screw due to physeal growth is rare. We report epiphyseal migration off bilateral screws in a child undergoing thyroid replacement therapy. Patients with mild and moderate slipped capital femoral epiphysis and endocrine...

Leg Equalization by Epiphyseal Arrest 1952-1970 Mr. J. G. H. James (Cardiff and Neath) reviewed a personal series of 246 cases of leg disparity: 114 had been followed to maturity and 67 cases of epiphyseal stapling were analysed in detail. The intention was to staple one or both epiphyses under direct vision with accurate placement of the posterior femoral and lateral tibial staples particularl...

Fractures of the proximal epiphysis of the tibia are rare, representing 0.5 to 3.0% of all epiphyseal injuries. These injuries can damage the popliteal vessels and their bifurcation, affecting the blood supply of the lower limb, as well as the nerves below the knee. Epiphyseal growth arrest is also a potential complication, leading to various angular deformities. We present a case of a 13-year-...

Introduction: Low-intensity doses of ultrasound are currently used in the treatment of various musculoskeletal conditions. However, this ultrasonic therapy may be contraindicated in children due to the potential for growth disturbances, particularly at the epiphyseal plates of the long bones. We hypothesize that current clinical therapeutic doses of ultrasound (0.5 W/cm2) will not cause prematu...

We previously reported on the A. thaliana gene EDM2, which is required for several developmental processes and race-specific immunity. Although EDM2 encodes a nuclear protein with features commonly observed in epigenetic factors, its role in chromatin silencing remains unknown. Here we demonstrate that silencing states of several transposons in edm2 mutants are altered. Levels of their transcri...

A procedure for the study of glycogen in the same cell, under both light and electron microscopes is described. The synthesis and accumulation of glycogen is a feature of chondrogenesis in the mouse epiphyseal cartilage and the amount of glycogen increases with the progress of differentiation. In contrast, no glycogen was detected in differentiating epiphyseal cartilage of the chick at any stag...

Studies have shown that mutations in the matrilin-3 gene (MATN3) are associated with multiple epiphyseal dysplasia (MED) and spondyloepimetaphyseal dysplasia (SEMD). We tested whether MATN3 mutations affect the differentiation of chondroprogenitor and/or mesenchymal stem cells, which are precursors to chondrocytes. ATDC5 chondroprogenitors stably expressing wild-type (WT) MATN3 underwent sponta...

Ferromagnetic resonance has been used to investigate the inter-layer coupling in a bilayered manganite La(2-2x)Sr(1+2x)Mn(2)O(7) (x = 0.38) single crystal. The coexistence of a ferromagnetic resonance line and a paramagnetic resonance line was observed over a broad temperature range. Antiferromagnetic coupling between the adjacent MnO(2) bilayers can be identified from the observation of an opt...
