Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve or its branches in the fibro-osseous tunnel beneath the flexor retinaculum. This pathology is associated with multiple etiologies, including trauma, space-occupying lesions, and impaired biomechanics. We report a case of tarsal tunnel syndrome associated with gout tophi in a patient with untreated gout along with a review of the relevant literature on tarsal tunnel syndrome.

BACKGROUND: Cytokine-mediated ex vivo expansion has been proposed as a means of increasing the number of cord blood (CB) hematopoietic stem cells for transplantation. As well as stem cell number, stromal cells are necessary for functional maturation of hematopoiesis. The purpose of this study was to analyze the development of stromal cells during ex vivo expansion of CB CD34+ cells. METHODS: CD34+ cells were purified from CB by magnetic bead selection. The levels of of interleukin-3, interleukin-1 beta, interleukin-6, granulocyte macrophage-colony stimulating factor and tumor necrosis factor-alpha were measured in culture supernatants on 0, 1, 2, and 3 weeks, using ELISA techniques. CB CD34+ cells were expanded in Iscoves modified Dulbeccos medium in the presence of several cytokines. The expression of E-selectin, vascular cell adhesion molecule- 1, intercellular adhesion molecule- 1, platelet/endothelial cell adhesion molecule-1, von Willebrand factor, vimentin, and CD14 in newly developed stromal cells was examined by immunocytochemical method. Relevant extracellular matrix (ECM) proteins and proper cytokines were also assayed for the most suitable condition for expansion of stromal cells. RESULTS: Several cytokines were found to have been produced by CB CD34+ cells as well as bone marrow-derived CD34+ cells. During ex vivo expansion of CB CD34+ cells, stromal cells appeared in the culture by day 4 and expanded over the following 7- 10 days before being confluent by day 2 1. These cells expressed surface markers characteristic of cells of endothelial lineage. Furthermore, these stroaml cells also expanded effectively when treated with thrombopoietin+flt-3 ligand+stem cell factor+leukemia inhibitory factor or 0. 1% poly-L-lysine-coated wells. CONCLUSION: Stromal cells were developed during ex vivo expansion of CB CD34+ cells and that this development could be enhanced further by treating the stromal cells with cytokines or ECM.

Growth hormone (GH) has been available for more than 4 decades for the treatment of GH deficiency. But mass production of recombinant DNA growth hormone has made GH therapy widely available for children with no GH deficiency. The use of GH therapy in children has resulted in adverse effects ranging from minor disturbances such as edema and injection site reactions to more significant, but rare events such as benign intracranial hypertension and slipped capital femoral epiphysis. Yet there has been no report in the dermatological field on skin adverse effects associated with GH therapy. We report here on 2 cases of psoriasis following GH therapy in children.

INTRODUCTION: Hydroxyapatite (Ca10(PO4)6(OH)2, HA) is the main inorganic phase of human hard tissue that is used widely as the repair material for bones. When HA is applied to a bony defect, however, it can be encapsulated with fibrous tissue and float in the implanted area due to a lack of consolidation. Bioceramics as allogenic graft materials are added to HA to improve the rate and bone healing capacity. Fluoridated hydroxyapatite (Ca10(PO4)6(OH,F)2, FHA), where F- partially replaces the OH- in hydroxyapatite, is considered a good alternative material for bone repair owing to its solubility and biocompatibility. MATERIALS AND METHODS: This study was designed to determine the bone healing capacity of FHA newly produced as a nanoscale fiber in the laboratory. HA and FHA with bioglass was implanted in a rabbit cranium defect and the specimen was analysed histologically. RESULTS: 1. At 4 weeks, fibrous connective tissue and little bone formation was observed around the materials of the experimental group I implanted HA and bioglass. Newly formed bone was observed around the materials in the experimental group II implanted FHA and bioglass. 2. At 8 weeks, the amount of newly formed and matured bone was higher in experimental group II than in experimental group I and the control group. CONCLUSION: These results suggest that FHA and bioglass is a relatively favorable bone substitute with biocompatibility and better bone healing capacity than pure HA and bioglass.

Leakage studies have been performed frequently, since a fluid-tight seal provided by various dental filling materials has been considered clinically important. The leakage of the various root-end filling materials has been widely investigated mostly dye penetration method. These dye studies cannot offer any information about the quality of the seal of a test material over a long period of time The purpose of this study was to evaluate the microleakage of root end cavities in blood contamination filled amalgam, intermediate restorative material(IRM), light cured glass ionomer cement(GI) and mineral trioxide aggregate(MTA) by means of a modified fluid transport model. Fifty standard human root sections, each 5mm high and with a central pulp lumen of 3mm in diameter, were and filled with our commonly used or potential root end filling materials after they were contaminated with blood. At 24h, 72h, 1, 2, 4, 8, and 12 weeks after filling, leakage along these filling materials was determined under a low pressure of 10KPa(0.1atm) using a fluid transport model. The results were as follows: 1. MTA group showed a tendency of decreasing percent of gross leakage (20ml/day) in process of time, whereas the other materials showed a tendency of increasing in the process time. 2. At the all time interval, GI group leaked significantly less than amalgam group and IRM group (p<0.05). 3. At the 4 weeks, the percentage of gross leakage in MTA group decreased to 0% thereafter, the low percentage of gross leakage was maintained in MTA group until the end of the experiment, whereas the percentage in IRM group increased to 100%. 4. At the 12 weeks, percentage of gross leakage was significantly low in MTA group(0%), comparison with GI group(40%), amalgam group(90%) and IRM group(100%), but there was no significant difference between latter two materials.

OBJECTIVE: To investigate whether early postmastectomy rehabilitation program could improve shoulder function and upper limb edema. METHOD: 40 patients who underwent either a breast conserving procedure or a modified radical mastectomy were included. Among 40 patients, 20 patients recieved early postmastectomy rehabilitation program and 20 patients were recieved only instruction for exercise. The patients were assessed on the three days after surgery and one month after surgery. The range of motion (ROM) of shoulder, pain on mobility of shoulder and arm circumference were evaluated. RESULTS: One month after surgery, both groups showed improvements in shoulder motion range, pain and edema. But there were significantly better in early rehabilitation group than control group (p <0.05). CONCLUSION: We concluded that early postmastectomy rehabilitation program was beneficial in regaining the shoulder motion and in reduction of pain and edema.
