Leiomyosarcoma (LMS) is a soft tissue sarcoma that originates from smooth muscle cells and constitutes approximately 5–10% of all soft tissue sarcomas. Vascular LMS is the least common subtype of LMS. About one-third of vascular LMS is located in the extremities, most commonly in the saphenous vein (25%). Vascular LMS originating from the popliteal vein is very rare, and to the best of our knowledge, only nine cases have been reported to date. Case presentation. We herein report a case of a 49-year-old woman who presented with recurrence of a mass that was located at the posterior aspect of the right proximal leg and extended to the popliteal fossa. She had mild pain and intermittent claudication without a history of an edematous leg. The tissue diagnosis was LMS. Wide en bloc resection of the tumor, including the segment of the involved popliteal vein, was performed without venous reconstruction. The patient received no other adjuvant treatments. At the 16-month follow-...

To evaluate the outcome of percutaneous release of the A1 pulley in 40 cadaveric fingers using a modified Kirschner wire. Methods. A 2.5-mm-diameter Kirschner wire measuring>12 cm in length was used. One end of the wire was sharpened into a ‘J ’ shape using a grinder. The J-shaped tip featured a blunt, elongated lower tip, a sharp J-shaped curve, and a blunt upper tip. Completeness of A1 pulley release and injuries to the A2 pulley, flexor tendon, and neurovascular structures were evaluated in 40 cadaveric fingers. Results. Complete release of the A1 pulley was achieved in 8 index, 7 middle, 8 ring, and 8 little fingers, whereas incomplete release of the distal part was noted in 2 index, 2 middle, 2 ring, and one little fingers; release was missed in one middle and one little fingers. Injury to the A2 pulley was noted in 2 index fingers; the injury was minimal and limited to the proximal 2 mm of the A2 pulley. There was no flexor tendon or digital nerve injury in any fin...

Musculoskeletal tuberculosis usually presents with bursitis, synovitis, myositis, and osteomyelitis, conditions which demonstrate an excellent response to antituberculosis chemotherapy. Tendon rupture is often associated with delayed diagnosis and treatment. We report a rare manifestation of musculoskeletal tuberculosis in the distal biceps tendon with delayed diagnosis.

Overview of Literature: Epidural fibrosis is a common cause of failed back surgery syndrome. Many animal experiments have been developed to investigate the prevention of epidural fibrosis. One of the common outcome measurements is the epidural fibrous adherence grading, but the classification has not yet been validated. Methods: Five identical sets of histopathological digital files of L5-L6 laminectomized adult Sprague-Dawley rats, representing various degrees of postoperative epidural fibrous adherence were randomized and evaluated by five independent assessors masked to the study processes. Epidural fibrosis was rated as grade 0 (no fibrosis), grade 1 (thin fibrous band), grade 2 (continuous fibrous adherence for less than two-thirds of the laminectomy area), or grade 3 (large fibrotic tissue for more than two-thirds of the laminectomy area). A statistical analysis was performed. Results: Four hundred slides were independently evaluated by each assessor. The percent agreement and intraclass correlation coefficient (ICC) between each pair of assessors varied from 73.5% to 81.3% and from 0.81 to 0.86, respectively. The overall ICC was 0.83 (95% confidence interval, 0.81-0.86). Conclusions: The postoperative epidural fibrosis classification showed almost perfect agreement among the assessors. This classification can be used in research involving the histopathology of postoperative epidural fibrosis; for example, for the development of preventions of postoperative epidural fibrosis or treatment in an animal model.

Recent data demonstrated the important role of the receptor activator of nuclear factor-κB (RANK)/RANK-ligand (RANKL) pathway in the pathogenesis. However, the roles of RANK and RANKL in predicting recurrence have never been proposed. Therefore, we aim to investigate the prognostic value of RANK and RANKL expression in predicting recurrence of GCTB which may change the treatment paradigm of the disease. Method: 53 cases of GCTB were enrolled in the study. Data on patient demographics and clinical characteristics were reviewed. Immunohistochemistry was used to detect the expression of RANK and RANKL. Recurrence-free survival (RFS) analysis was performed by Kaplan–Meier method and the difference between survival curves were sought using the log-rank test. Cox’s proportional hazards model and binary logistic regression analyses were used to define the risk of recurrence. Result: Of 53 cases, there were 8 patients (15.1%) had recurrent disease. The univariate analysis revealed that age (log rank 10.749, p=0.005), RANKL overexpression (log rank 5.187, p=0.023), RANK overexpression (log rank 4.055, p=0.044 for RANK) and co-overexpression of RANK/RANKL (log rank 7.541, p<0.006) were associated with recurrence of GCTB. Cox’s proportional hazards model emerged that the only significant prognostic parameter capable of defining the risk for recurrence was co-overexpression of RANK and RANKL (Hazard ratio 2.910; 95%CI 1.099-7.708; p= 0.032). Binary logistic regression multivariate analysis followed by ROC analysis confirmed that cooverexpression of RANK/RANKL represented a significant biological model to predict local recurrence (area under the curve=0.731±0.098; 95% CI 0.539–0.922, p=0.039). Conclusion: RANK and RANKL co-overexpression increases the risk of recurrence of GCTB and could be a prognostic marker for recurrent disease.

Material and Method: The authors developed the Thai version of the Medical Outcomes Study Short-Form Survey version 2.0 (SF-36V2) and tested it in 100 low back pain patients. Reliability of the Thai version of SF-36V2 was assessed by internal consistency using Chronbach's alpha coefficient and item-scale correlation. Results: The authors demonstrated that the Chronbach's alpha coefficient of the physical health and mental health summary scales were 0.93 and 0.92 respectively. The Chronbach's alpha coefficient of eight scales in the Thai version of the SF-36V2 ranging was 0.72-0.94. The Chronbach's alpha coefficient tested in acute or chronic low back pain patients whether they have back pain only or back pain with radiculopathy ranging was 0.72-0.93. The item correlation coefficient for the 35 items within the eight health aspects ranged from 0.43 to 0.8. Conclusion: The Thai version of the Medical Outcomes Study Short-Form Survey version 2.0 (SF-36V2) is a reliable tool for assessing functional disability of low back pain in Thai patients.

To examine whether combination of corticosteroid and bupivacaine administered in patients undergoing posterior lumbosacral spine surgery reduces postoperative morphine consumption, back and leg pain relief, and improves functional disability and general health status. Patients with lumbar spine surgery had moderate to severe postoperative pain. Administration of corticosteroid or injection of local anesthetic agent has been additive treatment methods for opioid drugs. There is uncertainty as to whether corticosteroid and bupivacaine combination improves outcomes in lumbosacral spine surgery. A total of 103 patients who were scheduled to undergo elective posterior lumbar discectomy, decompressive laminectomy with or without instrumented fusion for degenerative spinal diseases, received either methylprednisolone locally applied to the affected nerve roots (and bupivacaine ...
