https://www.selleckchem.com/ Background Although cases of impaired long bone growth due to bone and joint infections in childhood are sometimes reported, few cases of growth impairment of the ulna due to septic osteomyelitis have been described. We report herein a case of ulnar partial physeal arrest treated using the Langenskiöld procedure. Materials and Methods A boy developed septic osteomyelitis of the right distal ulna at age 2 years 6 months. Osteomyelitis subsided after antibiotic treatment and external immobilization. As a result of impaired growth of the ulna along the long axis, shortening and trumpet-shaped deformity of the metaphysis gradually appeared. Computed tomography revealed a bony bridge, and premature epiphyseal closure due to osteomyelitis was diagnosed. The Langenskiöld procedure was performed at 4 years 4 months old. Results As of 2 years 9 months later, no further ulnar shortening has occurred and morphological remodeling has been confirmed. Conclusions The treatments employed for ulnar shortening include ulnar lengthening by callotasis as well as stapling of the distal radial epiphyseal line or radial shortening osteotomy. In this case, the Langenskiöld procedure proved effective because the patient was still young with growth potential and the area of the bony bridge after osteomyelitis-induced epiphyseal line damage was less then 30%.Skin aging is primarily associated with the alterations in dermal extracellular matrix, in particular a decrease in collagen type-1 content. Recent studies have shown that collagen-degrading matrix metalloproteinase (MMP-1) is produced by fibroblasts in response to chronoaging, which in human dermal fibroblasts leads to the release of proinflammatory cytokines. Past studies showed that anti-inflammatory capabilities could be induced via non-chemical means. One of these methods makes use of ultra-weak fractal electromagnetic (uwf-EM) signals. Such ultra-/very-low frequency (U/VLF) signals (few nT in intensity
