Simultaneous hybrid closed-wedge supramalleolar osteotomy and ankle arthrodesis for post-traumatic varus ankle arthritis with periarticular deformity: A case report.

The treatment of end-stage ankle arthritis associated with extra-articular tibial deformity, especially for ankles deformed by previous traumatic injuries and/or surgical treatment, is extremely challenging but rewarding. Only one previous report describes simultaneous tibial deformity correction and ankle arthrodesis for tibial malalignment and ipsilateral ankle arthritis. Here, we describe a unique case of post-traumatic ankle osteoarthritis concomitant with extra-articular varus deformity in a 77-year-old female.

Allergenicity of Deamidated and/or Peptide-Bond-Hydrolyzed Wheat Gliadin by Transdermal Administration.

Hydrochloric acid (HCl)-treated wheat protein (HWP) is widely used in various products, including foods, cosmetics and shampoos. Recently, immediate hypersensitivity towards facial soap containing HWP has been reported. HCl treatment of protein causes hydrolysis not only of main-chain amide bonds (peptide-bond hydrolysis) but also of side-chain ones (deamidation).

Calcaneocuboid Distraction Arthrodesis With Synthetic Bone Grafts: Preliminary Results of an Innovative Bone Grafting Procedure in 13 Patients.

Calcaneocuboid distraction arthrodesis (CCDA) is regarded as an effective method for reconstructing adult-acquired flatfoot deformity. In the present study, we present our experience with newly developed rigid β-tricalcium phosphate wedges to treat CCDA to better understand the outcomes of this synthetic bone grafting procedure. A total of 13 feet in 13 patients underwent CCDA with synthetic bone grafts.

Treatment of Varus Ankle Osteoarthritis and Instability With a Novel Mortise-Plasty Osteotomy Procedure.

Although joint-preserving surgery for intermediate ankle osteoarthritis has been reported to be effective, failures of supramalleolar osteotomy and plafond-plasty can occur because of persistent malalignment of the distal tibia and incongruent ankle mortise. We introduce a novel opening wedge distal tibial osteotomy procedure (mortise-plasty) with rigid plate fixation combined with synthetic bone wedges. We performed 27 mortise-plasties in 25 patients with varus ankle osteoarthritis and instability.

Gradual Correction of Traumatic Hallux Varus With Metatarsal Hemicallotasis.

Traumatic hallux varus associated with osseous deformity, especially in the case of a decreased distal metatarsal articular angle, is an extremely challenging, but rewarding, deformity to treat. To the best of our knowledge, no previous reports have referred to surgical correction of traumatic hallux varus using first metatarsal hemicallotasis. We report the case of a 54-year-old male with traumatic hallux varus associated with medial subluxation of the second metatarsophalangeal joint and second metatarsocuneiform joint arthrosis.

Isolated Fifth Metatarsocuboid Coalition: A Case Report.

Isolated tarsometatarsal coalitions are extremely rare, and the previous 5 documented cases involved the first and third metatarsocuneiform joints. We report the case of a 69-year-old female with symptomatic fifth metatarsocuboid coalition associated with ipsilateral varus-type ankle osteoarthritis and instability. The patient was successfully treated by arthrodesis of the fifth metatarsocuboid joint, resection of the hypertrophied tuberosity of the fifth metatarsal, advancement of the peroneus brevis tendon, opening wedge distal tibial osteotomy, and calcaneal displacement osteotomy.

Accumulating microglia phagocytose injured neurons in hippocampal slice cultures: involvement of p38 MAP kinase.

In this study, microglial migration and phagocytosis were examined in mouse organotypic hippocampal slice cultures, which were treated with N-methyl-D-aspartate (NMDA) to selectively injure neuronal cells. Microglial cells were visualized by the expression of enhanced green fluorescent protein. Daily observation revealed microglial accumulation in the pyramidal cell layer, which peaked 5 to 6 days after NMDA treatment.

Neuronal injury induces microglial production of macrophage inflammatory protein-1α in rat corticostriatal slice cultures.

Chemokines are potent chemoattractants for immune and hematopoietic cells. In the central nervous system, chemokines play an important role in inflammatory responses through activation of infiltrating leukocytes and/or resident glial cells. We previously demonstrated that N-methyl-D-aspartate (NMDA)-evoked neuronal injury induced astrocytic production of monocyte chemoattractant protein-1 (MCP-1, CCL2) via sustained activation of extracellular signal-regulated kinase (ERK) in rat organotypic slice cultures.

Etanercept treatment reduces the serum levels of interleukin-15 and interferon-gamma inducible protein-10 in patients with rheumatoid arthritis.

Tumor necrosis factor-alpha (TNF-alpha) has an essential role in the pathogenesis of rheumatoid arthritis (RA) and has been known to induce the production of several inflammatory molecules in vivo. To analyze in vivo the active mechanism of the TNF-alpha blocking agent, etanercept, the serum levels of the cytokine interleukin-15 (IL-15) and the chemokines growth-regulated protein-alpha (Gro-alpha), and interferon-gamma inducible protein-10 (IP-10) in RA patients were measured. Twenty-two patients with RA were administered etanercept once or twice a week for more than 6 months.

Infliximab treatment reduces the serum levels of interleukin-23 in patients with rheumatoid arthritis.

In this study, we investigated the effect of the antitumor necrosis factor alpha (anti-TNF-alpha) antibody, infliximab, combined with methotrexate (MTX) and MTX alone on the serum levels of interleukin (IL)-23 and IL-17 in rheumatoid arthritis (RA) patients. Infliximab combined with MTX was administered to 26 patients with RA (infliximab group), and MTX alone was given to 20 patients with RA (MTX group). We evaluated clinical and laboratory parameters, including the Disease Activity Scores of 28 joints (DAS28) and serum levels of IL-23 and IL-17 at baseline and at 14 and 30 weeks after the initial treatment with these drugs.

Etanercept reduces the serum levels of macrophage chemotactic protein-1 in patients with rheumatoid arthritis.

This study was performed to analyze the effect of etanercept, the soluble tumor necrosis factor-alpha (TNF-alpha) receptor, on the serum levels of several chemokines including monocyte chemotactic protein-1 (MCP-1), regulated upon activation normal T expressed and presumably secreted (RANTES), and granzyme B in rheumatoid arthritis (RA) patients. Twenty-eight patients with RA were administered etanercept once or twice a week for more than 6 months. Clinical and laboratory parameters were measured and serum levels of MCP-1, RANTES, and granzyme B were determined using enzyme-linked immunosorbent assay (ELISA) kits at baseline and at 3 and 6 months after the initial treatment.

Reduction of urinary levels of pyridinoline and deoxypyridinoline and serum levels of soluble receptor activator of NF-kappaB ligand by etanercept in patients with rheumatoid arthritis.

The effects of soluble TNF-alpha receptor, etanercept, on bone metabolism were investigated in patients with rheumatoid arthritis (RA). Thirty RA patients were administered etanercept once or twice a week for more than 6 months. We evaluated clinical and laboratory parameters and measured urinary excretion levels of pyridinoline (PYD), deoxypyridinoline (DPD), cross-linked N-telopeptides of type I collagen (NTX), and serum levels of bone alkaline phosphatase (BAP), osteoprotegerin (OPG), and soluble receptor activator of NFkappaB ligand (sRANKL) at the baseline and at 3 and 6 months after initial treatment with etanercept.

Successful introduction of modified dorsolumbar epidural anesthesia in a bovine referral center.

This study describes the successful use of modified dorsolumbar epidural anesthesia with a fixed volume of anesthetic in a bovine referral center. Among the 130 Holstein cattle scheduled for flank surgery, 90 cattle received a mixed anesthetic consisting of 1 ml of xylazine hydrochloride and 3 ml of lidocaine hydrochloride by modified dorsolumbar epidural anesthesia. Eighteen cattle with dehydration and/or lameness received a mixed anesthetic containing 0.

Osteoma arising from the lumbar articular process.

A 57-year-old man presented with an extremely rare osteoma originating from the left L-5 inferior articular process and causing lumbo-crural sciatica. Postmyelography computed tomography and magnetic resonance imaging showed an osteoma compressing the spinal nerve root at the lateral recess. Decompression facetectomy and excision of the lesion followed by transforaminal lumbar interbody fusion between L-5 and S-1 provided complete relief from the symptoms.
