OBJECTIVE: To investigate the shoulder disease patterns for the table-tennis (TT) and archery (AR) wheelchair athletes via ultrasonographic evaluations. METHODS: A total of 35 wheelchair athletes were enrolled, made up of groups of TT (n=19) and AR (n=16) athletes. They were all paraplegic patients and were investigated for their wheelchair usage duration, careers as sports players, weekly training times, the Wheelchair User's Shoulder Pain Index (WUSPI) scores and ultrasonographic evaluation. Shoulders were divided into playing arm of TT, non-playing arm of TT, bow-arm of AR, and draw arm of AR athletes. Shoulder diseases were classified into five entities of subscapularis tendinopathy, supraspinatus tendinopathy, infraspinatus tendinopathy, biceps long head tendinopathy, and subacromial-subdeltoid bursitis. The pattern of shoulder diseases were compared between the two groups using the Mann-Whitney and the chi-square tests RESULTS: WSUPI did not significantly correlate with age, wheelchair usage duration, career as players or weekly training times for all the wheelchair athletes. For the non-playing arm of TT athletes, there was a high percentage of subscapularis (45.5%) and supraspinatus (40.9%) tendinopathy. The percentage of subacromial-subdeltoid bursitis showed a tendency to be present in the playing arm of TT athletes (20.0%) compared with their non-playing arm (4.5%), even though this was not statistically significant. Biceps long head tendinopathy was the most common disease of the shoulder in the draw arm of AR athletes, and the difference was significant when compared to the non-playing arm of TT athletes (p<0.05). CONCLUSION: There was a high percentage of subscapularis and supraspinatus tendinopathy cases for the non-playing arm of TT wheelchair athletes, and a high percentage of biceps long head tendinopathy for the draw arm for the AR wheelchair athletes. Consideration of the biomechanical properties of each sport may be needed to tailor specific training for wheelchair athletes.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

BACKGROUND: Few studies have investigated the effects of sarcopenia on postoperative outcomes including mortality rates following surgery for osteoporotic hip fractures. The purpose of the present study was to determine the prevalence of sarcopenia and the relationship between sarcopenia and 1- and 5-year mortality rates in a consecutive series of patients with osteoporotic hip fractures. METHODS: Among patients who underwent hip surgery for osteoporotic hip fractures, this study included 91 patients subjected to abdominal computed tomography within 1 year of hip surgery. We defined sarcopenia using sex-specific cut-off points for the skeletal muscle index at the level of the third lumbar vertebra. All patients were divided into 2 groups according to the presence or absence of sarcopenia and the 1- and 5-year mortality rates were compared. To confirm factors affecting mortality in addition to sarcopenia, we examined patient age, sex, American Society of Anesthesiologists grade, location of fracture, type of surgery, and bone mineral density. RESULTS: The 1- and 5-year mortality rates were 20.9% and 67.2%, respectively. Among the 45 patients with sarcopenia, the 1- and 5-year mortality rates were 22.2% and 82.7%, respectively. Of the 46 patients without sarcopenia, the 1- and 5-year mortality rates were 19.6% and 52.7%, respectively. Results of the Kaplan-Meier analysis showed that sarcopenia did not affect the 1-year mortality rate (P=0.793), but had a significant effect on the 5-year mortality rate (P=0.028). Both perioperative sarcopenia (P=0.018) and osteoporosis (P=0.000) affected the 5-year mortality rate. CONCLUSIONS: Sarcopenia increases the risk of 5-year mortality in patients with osteoporotic hip fractures.

PURPOSE: The purpose of this study is to report the postoperative clinical results after arthroscopic ACL reconstruction using quadrupled hamstring autograft fixed with biodegradable interference screw and bone block in the femoral tunnel. MATERIALS AND METHODS: Between January and December 1997, we performed an arthroscopic ACL reconstruction with quadrupled hamstring autograft in twenty one patients. To enhance the mechanical stability in the femoral tunnel the graft was fixed with a biodegradable interference screw and cortical bone block which was harvested from the proximal tibial metaphysis. The tibial side of graft was tied at the post of an AO cortical screw. Postoperatively the patients were permitted an accelerated rehabilitation with motion brace. The results were evaluated with IKDC form, complications and radiologic findings. The average follow-up was 36 months. RESULTS: Patient subjective assessment was graded normal in 4, nearly normal in 8, abnormal in 7, severe abnormal in 2. Ligament evaluation was graded normal in 16, nearly normal in 3, abnormal in 1, severe abnormal in 1. Harvest site pathology was graded normal in 16, nearly normal in 4, abnormal in 1. Functional test was graded normal in 6, nearly normal in 8, abnormal in 4, severe abnormal in 3. Radiologic findings showed an average 22% increase in the tibial tunnel diameter. Postoperative complications were one recurrent patholaxity, deep infection and arthrofibrosis required operation in each. CONCLUSION: Arthroscopic ACL reconstruction using quadrupled hamstring autograft fixed with biodegradable interference screw and bone block in the femoral tunnel provided with excellent ligament stability and permitted the early accelerated rehabilitation.

Background:
Hip fracture surgery is associated with blood loss, which may lead to adverse patient outcomes. The hemoglobin level declines gradually in most hip fracture cases involving femoral neck fractures and intertrochanteric fractures. It decreases further after hip fracture surgery due to perioperative bleeding. We developed a protocol, which avoids transfusion in hip fracture surgery, and reviewed the hemodynamic outcomes of patients with hemoglobin less than 10 g/dL without transfusion.
Methods:
From 2014 to 2019, we retrospectively recruited 34 patients with hip fractures and a hemoglobin level less than 10 g/dL, who refused to undergo transfusion. There were 19 patients with femoral neck fractures and 15 patients with intertrochanteric fractures. Our patient blood management (PBM) protocol involving 4,000 U erythropoietin (3 times a week) and 100 mg iron supplement (every day) was applied to all included patients. Intraoperatively, a cell saver and tranexamic acid were used. Postoperatively, the protocol was maintained until the patients’ hemoglobin level reached 10 g/dL. We evaluated the feasibility of our protocol, perioperative complications, and hemodynamic changes.
Results:
Nineteen patients with femoral neck fractures underwent bipolar hemiarthroplasty and 15 patients with intertrochanteric frac tures underwent internal fixation with a cephalomedullary nail. The mean hemoglobin level was 8.9 g/dL (range, 7.3–9.9 g/dL) pre operatively, 7.9 g/dL (range, 6.5–9.3 g/dL) immediately postoperatively, 7.7 g/dL (range, 4.3–9.5 g/dL) on postoperative day 1, 7.4 g/dL (range, 4.2–9.4 g/dL) on postoperative day 3, 8.1 g/dL (range, 4.4–9.7 g/dL) on postoperative day 5, 8.5 g/dL (range, 4.5–9.9 g/dL) on postoperative day 7, and 9.9 g/dL (range, 5.7–11.1 g/dL) on postoperative day 14. The average intraoperative bleeding was 206.2 ± 78.7 mL. There was no case associated with complications of anemia.
Conclusions
Hip fracture surgery in patients with hemoglobin less than 10 g/dL was feasible without the need for transfusion using our PBM protocol in 34 patients. Using this protocol, the operation was conducted safely despite the anemic condition of patients with fractures whose hemoglobin was less than 10 g/dL.
