Non healing chronic wounds are difficult to treat in patients with diabetes and can result severe medical problems for these society. Negative-pressure wound therapy (NPWT) has been adopted intractable reported be effective. However, the mechanisms underlying effects of this treatment have not elucidated. To assess vasculogenic effect NPWT, we evaluated systemic mobilization endothelial progenitor cells (EPCs) during NPWT. Twenty-two 29 consecutive who presented at clinic Seoul National...
Platelet-rich plasma (PRP) has been applied as an adjuvant treatment for arthroscopic rotator cuff repair (ARCR) to enhance healing. However, it remains debatable whether PRP enhances tendon-to-bone healing.To assess the efficacy of intraoperative augmentation and postoperative injection that was prepared using double-spin method calcium activation without thrombin in patients with ARCR.Randomized controlled trial; Level evidence, 1; cohort study; 3.A total 58 underwent ARCR augmentation....
This study aimed to develop a highly efficient nanofilter for capturing fine particles using electrostatic forces. Poly(vinyl alcohol) (PVA), water-soluble synthetic polymer, was selected as the main component of filter because it can be easily fabricated by electrospinning. Titanium dioxide (TiO2) nanopowder with an anatase structure applied nanofilters has highest photocatalytic activity among existing photocatalysts. PVA electrospinning could still dissolved in water hydrolysis....
The treatment of simple bone cysts (SBC) in children varies significantly among physicians. This study examined which procedure is better for the SBC, using a decision analysis based on current published evidence.A tree focused five modalities SBC (observation, steroid injection, autologous marrow decompression, and curettage with graft) were created. Each modality was further branched, according to presence severity complications. probabilities all cases obtained by literature review. A...
It has been reported that vitamin D may play an important role in rotator cuff tears. However, there limited information about the prevalence of and risk factors for hypovitaminosis patients with Therefore, purpose current study was to investigate tears.One hundred seventy-six (age, 61.9 ± 8.90 years) who underwent arthroscopic repair a full-thickness tear were enrolled this retrospective study. Preoperative serum levels (25-hydroxyvitamin D) measured. Hypovitaminosis defined as...
Baseball players are subjected to repeated loads on the supraspinatus and long head biceps tendon from youth, repetitive pitching motions can cause shoulder injuries. The purpose of this study was evaluate immediate changes caused by in muscle-tendon, bicep (LHBT), range motion (ROM) verify their recovery over time youth baseball players.Fifteen (mean age, 11.5 ± 1.3 years) were enrolled. thicknesses LHBT strain ratios (SRs) muscle measured sonoelastography. ROMs joints (abduction, external...
Ewing's sarcoma is rarely foundoccurs in the bones of hands and feet.We report a case left calcaneus 15-year-old girl who complained heel pain swelling.An open biopsy was performed histological examination showed proliferation uniform small round cells.Immunohistochemical staining for CD99 diffuse strong positivity cytoplasmic membrane tumor cells.After preoperative chemotherapy, below knee amputation performed.
Purpose : Magnetic resonance diffusion tensor imaging-based three-dimensional fiber tractography (DTI-FT) is a new method which demonstrates the orientation and integrity of white matter fibers in vivo. However, clinical application on children with cerebral palsy still under investigation. We present various abnormal patterns DTI-FT findings accordance rate hemiplegic palsy, to recognize usefulness DTI-FT. Methods The thirteen evaluated at Yeungnam University hospital from March, 2003...
Hydrogels are three-dimensional and hydrophilic polymer which can be formed by cross-linking chain swell but not dissolve in water.It applied to many fields, such as agriculture, hygiene products, wastewater treatment, drug delivery system.Semi-interpenetrating networks (semi-IPN) is a way of blending two polymers where only one crosslinked the presence another produce additional non-covalent interaction between polymers.Traditionally, most materials used make hydrogels synthetic...
Background: A ureteropelvic junction (UPJ) obstruction is a congenital anomaly commonly afflicting the pediatric population. However, it occurs more frequently in adults than generally appreciated. To assess their characteristics, we have here compared and analyzed clinical manifestations, causes, outcomes of UPJ found children adults. Materials Methods: 102 patients (118 renal units) out 182 (218 units), with diagnosed obstruction, were available for follow up. The follow-ups...
