The aims of this study were to identify risk factors for the recurrence hallux valgus deformity and clarify whether after surgery treat can be predicted using radiographic parameters assessed on immediate postoperative non-weight-bearing radiographs.A proximal chevron osteotomy combined with a distal soft-tissue procedure was performed by single surgeon moderate severe in 93 patients (117 feet). feet grouped according nonrecurrence or recurrence. Changes angle, intermetatarsal sesamoid...
Background/Objectives: Diabetic foot ulcers are one of the complications in patients with diabetes, which can be caused by infection, neuropathy, and blood vessel disorder. Among them, infection is most common cause, if it becomes worse, amputation may necessary. So, important to detect treat infections early, determining indicators that confirm also important. Known markers include white cells (WBCs), erythrocyte sediment rate (ESR), C-reactive protein (CRP), procalcitonin, but they not...
Abstract Background Intra-articular corticosteroid injection is commonly used for pain relief in ankle osteoarthritis (OA). The effects of corticosteroids (CS) are short-lived, whereas hyaluronic acid (HA) have longer-lasting effects. objective was to compare the efficacy dual injections CS and HA alone. We hypothesized that intra-articular agents would be more effective than Methods A single-blind, randomized, controlled trial designed investigate this hypothesis. 135 patients with OA were...
We report herein a case of benign cardiac schwannoma in the interatrial septum.A 42-year-old woman was transferred from clinic because cardiomegaly as determined by chest X-ray.A transthoracic echocardiography and computed tomography examination revealed huge mass pericardium compressing right atrium, superior vena cava (SVC), left pulmonary vein.To confirm that tumor originated either heart or mediastinum, cine magnetic resonance imaging performed, but result not conclusive.To facilitate...
This study evaluated the clinical results of arthroscopically assisted single and double bundle tibial inlay reconstructions an isolated posterior cruciate ligament (PCL) injury.This reviewed data for 14 patients who underwent a PCL reconstruction (Group A) 16 B) between August 1999 2002. The mean follow-up period in groups A B was 90.5 months 64 months, respectively.The Lysholm knee scores increased from average 43.3 +/- 7.04 44.7 5.02 preoperatively to 88.1 7.32 88.7 9.11 points at final...
The purpose of this study was to compare the results proximal and distal chevron osteotomy in patients with moderate hallux valgus. We retrospectively reviewed 34 osteotomies without lateral release (PCO group) 33 (DCO performed sequentially by a single surgeon. There were no differences between groups regard age, length follow-up, demographic or radiological parameters. clinical assessed using American Orthopaedic Foot Ankle Society (AOFAS) scoring system compared groups. At mean follow-up...
The anterior half of the peroneus longus tendon (AHPLT) has been reported to be an effective autograft for ligament reconstruction with respect strength and safety. However, there is little information regarding donor site morbidity after harvesting AHPLT. Furthermore, best our knowledge, not a study on isokinetic evaluation ankle plantar flexion eversion AHPLT harvesting.To evaluate clinical radiographic results lateral using We further investigated whether decreases eversion.Case series;...
Cell culture of human-derived neural stem cells (NSCs) is a useful tool that contributes to our understanding human brain development and allows for the therapies intractable disorders. Human NSC (hNSC) cultures, however, are not commonly used, mainly because difficulty with consistently maintaining in healthy state. In this study, we show hNSC unlike NSCs rodent origins, extremely sensitive insulin, an indispensable supplement, previously reported culturing hNSCs likely lack relationship....
One pathophysiological sign of sarcopenia is chronic inflammation. Given that levels red blood cell distribution width (RDW) are increased in inflammation, we evaluated the association between RDW and among adults general U. S. population analyzed data from 11,761 participants National Health Nutrition Examination Survey (NHANES) 1999-2006. Sarcopenia was defined as an appendicular skeletal muscle mass (ASM) divided by weight (%) less than one standard deviation (SD) below mean young adults....
This study was conducted to evaluate the usefulness of subtalar arthroscopy in operative treatment Sanders type 2 calcaneus fractures using a sinus tarsi approach.Forty-six calcaneal were consecutively treated approach. Intraoperative fluoroscopy used fracture reduction first 23 patients (fluoroscopy group), and intraoperative latter (arthroscopy group). Clinical evaluations performed visual analog scale, Ankle-Hindfoot Scale developed by American Orthopaedic Foot & Ankle Society, Short Form...
Background/Aims: Inflammatory bowel disease (IBD) is an autoimmune characterized by chronic inflammation mainly in the large intestine. The interleukin-10 knockout (IL-10 KO) mouse a well-known animal model of IBD that develops spontaneous intestinal resembling Crohn's disease. Oxidative stress considered to be leading cause cell and tissue damage. Reactive oxygen species (ROS) can direct injury and/or indirect inducing secretion cytokines from damaged cells. This study evaluated effects...
In hyperlipidemia, pyroptosis in endothelial cells (ECs) induces atherosclerosis via the toll-like receptor 4 (TLR4) pathway. We evaluated effects of Ecklonia cava extract (ECE) and pyrogallol-phloroglucinol-6,6-bieckol (PPB) on ECs vascular smooth muscle (VSMCs), which leads to attenuation these dysfunction aorta high-fat-diet (HFD)-fed mice palmitate-treated VSMCs. The expression TLR4 nuclear factor kappa-light-chain-enhancer activated B (NF-κB), induce formation NOD-LRR-and pyrin...
NK/T-cell lymphoma (NKTL) is strongly associated with latent Epstein-Barr virus (EBV) infection. Recently, membrane protein 1 (LMP1), an EBV oncoprotein, was reported to activate the phosphatidylinositol-3 kinase (PI3K)/Akt pathway for cell survival. Because geldanamycin (GA) and its derivative, 17-allylamino-17-demethoxygeldanamycin (17-AAG), exhibit anti-tumour activity by degrading HSP90 client proteins, including Akt, we investigated effect of GA 17-AAG on survival NKTL lines....
Aims The hypothesis of this study was that bone peg fixation in the treatment osteochondral lesions talus would show satisfactory clinical and radiological results, without complications. Methods Between September 2014 July 2017, 25 patients with symptomatic osteochondritis an fragment, who were treated using fixation, analyzed retrospectively. All available for complete follow-up at a mean 22 months (12 to 35). There 15 males ten females age 19.6 years (11 34). results evaluated visual...
No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi (STA) for Sanders type 2 calcaneal fractures. This was conducted to confirm whether STA prone fewer wound complications than ELA.Between August 2013 2018, 64 patients with calcaneus fractures were randomly assigned receive surgical treatment by ELA (32 patients) patients). The primary outcome development of complications. secondary outcomes postoperative complications, pain scored a visual...
