BACKGROUND: The purpose of the study was to compare the degree of degeneration of the articular and bursal layers of delaminated supraspinatus tendons based on histological examination. METHODS: Fifty-four patients with a full-thickness rotator cuff tear were included in the study. Tendon specimens were harvested during arthroscopic rotator cuff repair from the lateral torn edges of the articular and bursal layers of the delaminated tear. Harvested samples were stained with H&E dye and evaluated based on a semi-quantitative grading scale. RESULTS: There were no significant differences in the seven histological characteristics of tendon degeneration: fiber structure, fiber arrangement, round nuclei, regional variations in cellularity, vascularity, collagen stainability, and hyalinization between the articular and bursal layers of the delaminated rotator cuff tear (all p>0.05). Total degeneration scores of articular and bursal sides were 13.1 ± 3.85 points and 13.2 ± 3.42 points, respectively, and were not significantly different (p=0.958). CONCLUSIONS: The study demonstrates that tendon degeneration was similar in the articular and bursal sides of the delaminated fullthickness rotator cuff tear, suggesting that degeneration would be a main etiology for the rotator cuff tear not only in the articular side but also in the bursal side. Considering potential disadvantages of subacromial decompression, this study tentatively suggests routine use of subacromial decompression as well as the need for halting or recovery from rotator cuff degeneration for better rotator cuff repair.

To improve the graft survival in cadaveric donor renal transplantation, various factors that affect the results of allograft function has been analysed and reported. From January 1994 through December 1998, 39 cases of renal transplantation were performed using 20 cadaver donor. Thirty five of them were from brain dead donor and four from cardiac arrest donor. The most frequent cause of brain death was head injury by traffic accident, mostly autobicycle accident. Male donor ratio was 85.0% and their mean age were 29.3 years old. Mean cold ischemic time was 347.5 minutes and warm ischemic time of 4 cardiac arrest cases were 55-60 minutes. The number of HLA mismatch more than 4 were 64.1%. There were 8 cases of multiple renal arteries and 4 cases of double ureter. Donor hypotension during and before kidney procurement and warm ischemic time were factors that cause the delayed graft function in our cases. The number of HLA mismatch and use of Cellcept as immunosuppressant were two factors that affected the development of acute rejection during 6 months after renal allograft. Among the 39 kidneys of 20 donors, 12 paired kidneys showed different graft result in each recipient. Recipient age, number of HLA mismatch, cold ischemic time, duration of hemodialysis before transplantation, and level of hemoglobin were factors that cause the diffrerent result in paired kidney. One and two year graft survival rate were 89.6% and 76.5% respectively. In summary, the early results of our cadaver donor renal transplantation was comparable to living donor transplantation. Adequate donor management and HLA matching between donor and recipient are factors that can improve the graft result.

Bronchogenic cysts are rare congenital anomalies that are most frequently found in the mediastinum along the tracheobronchial tree, especially in the posterior aspect of the superior mediastinum. Bronchogenic cysts have also been reported in intrapulmonary, intrapericardial, abdominal, and retroperitoneal locations. Herein, we report a case of a retroperitoneal bronchogenic cyst in the presacral space. The patient was diagnosed based on a post-operative histopathological examination.

Health Technology Research and Development (R&D) national grant system has been progressed by the unique governance of each countries. From this reason, it has historical context and path-dependency. South Korea, also have started their investment from Bio Technology Master Plan of Ministry of Science and Technology (1994) and Korea Health Technology R&D Project of Ministry of Health and Welfare (1995), currently investing around 1.1 trillion won (in the year 2012) into the Ministry of Education, Science and Technology (now, Ministry of Science, ICT and Future Planning), Ministry of Health and Welfare and Ministry of Knowledge Economy (now, Ministry of Trade, Industry and Energy). This paper focuses on the Health Technology R&D national grant system in the aspect of governance, mid-long term strategic plan, main program, planning-evaluation-management system. And last but not least, implications. First, there would be important to build the effective governance, performance based policy and administration mechanisms of national grant system for the Health Technology R&D. Second, main objective of Health Technology R&D, which is improving the quality of life for the public, could not meet their target practically. Third, R&D investment has been enlarged from treatment based to prevention and care focused and from technology-centered into demand-centered, which based on the unmet health needs. Last, most of Health Technology R&D project could not consider sustainable health system, which would be the most important value in healthcare.

Light chain deposition disease (LCDD) is characterized by the deposition of abnormal immunoglobulin light chains in many organs, including kidney. It is usually associated with multiple myeloma or other lymphoproliferative disorders. Myeloma usually occurs in old age and may develop after renal transplantation thus being categorized as posttransplant lymphoproliferative disease (PTLD). Renal LCDD usually presents with variable degree of proteinuria and renal insufficiency. The diagnosis of LCDD depends on histologic findings with detection of monoclonal immunoglobulin light chain. Histologically, it is characterized by nodular glomerulosclerosis. We report the first case of de novo LCDD associated with myeloma after renal transplantation in Korea. With advancing renal transplantation and increasing old aged renal recipients, myeloma or LCDD should be included in the differential diagnoses of renal recipient patients with deteriorating renal function.

BACKGROUND: Massive, irreparable rotator cuff tears (RCTs) are a challenging clinical problem in young patients. In recent years, arthroscopic superior capsular reconstruction (ASCR) is a popular treatment in the massive, irreparable RCTs. However, studies reporting clinical results of ASCR are rare in the literature. METHODS: Between 2013 and 2015, six patients underwent ASCR. One patient treated with dermal allograft, while five patients with autogenous fascia lata graft. Demographic data, as well as preoperative and last follow-up clinical data including pain, range of motion (ROM), strength, American Shoulder and Elbow Surgeons system, the Constant system, the University of California at Los Angeles system, the Simple Shoulder Test, and the Shoulder Pain and Disability Index system were obtained. Acromiohumeral distances and Hamada classification were measured on standard anteroposterior x-ray. RESULTS: All patients were men, and the average age was 59.5 ± 4.18 years (range, 53–65 years).The minimum follow-up was 18 months with a mean follow-up was 27.33 ± 7.58 months (range, 18–36). All patients had postoperative improvement in pain scores and functional scores. The ROM and strength did not improve after surgery. The Hamada score progressed of radiographic stage in 2 patients. In the case of dermal allograft, there was graft failure 6 weeks after ASCR. CONCLUSIONS: Our results support the ASCR as a viable treatment for surgical salvage in massive, irreparable RCTs. This treatment option may provide patients with decreased pain and increased function. And studying our case of dermal allograft failure provides opportunities to decrease graft failure in ASCR using dermal allograft.
