ABSTRACT
BACKGROUND: The demand for Rh-related and other specific antigen negative donations has increased recently, and in response, we need to improve work efficiency while decreasing reagent consumption. Thus, we desire to create a ‘table of Nambu Blood Laboratory Center's own Rh-related and other antigen negative rate’. METHODS: We analyzed the results of Rh-related specific antigen test for 2,806,330 donors using ‘PK-7300’ and the results of manual test for 10,024 other blood type antigen-related specific and compound antigens. We made a table summarizing the results using two cases. RESULTS: The negative rate of Rh-related specific antigens was approximately 12.9% for C, 41.7% for c, 49.5% for E, and 9.2% for e antigens. The negative rate of compound antigens was increased when compared with the number of inspections. The negative rate for C and e antigens was increased from 90.1% to 97.3%, and that for E, c, and JKa was increased from 7.6% to 31.6%. CONCLUSION: The negative rate table made in July 2016 has been determined to be very effective in screening for specific and compound antigen negative blood. Also it was very efficient in terms of examining and supplying the compound antigen negative blood. It would be helpful to improve the supply of specific antigen negative blood to better meet the unique needs of each medical institution.

PURPOSE: The aim of this study was to investigate the changes in and implications of preoperative and postoperative serum uric acid levels in patients with living donor nephrectomy. MATERIALS AND METHODS: We studied 207 patients between 1998 and 2007 at our hospital undergoing living-donor nephrectomy for kidney transplantation. The serum uric acid level and estimated glomerular filtration rate (eGFR) were measured preoperatively and at 1 year postoperatively. We also analyzed multiple independent variables such as age, sex, blood pressure, body mass index (BMI), serum total cholesterol, hemoglobin, hematocrit, total protein, albumin, calcium, and phosphorus. RESULTS: The mean age of the study patients was 38.3+/-10.8 years. The mean serum uric acid concentration at 1 year after kidney donation was higher than preoperatively (5.05+/-1.39 mg/dl preoperatively vs. 5.85+/-1.14 mg/dl postoperatively) and was significantly greater in patients with hyperuricemia (uric acid> or =6.8 mg/dl) than in patients without hyperuricemia (uric acid or =5.7 mg/dl) require careful observation before and after living-donor nephrectomy.

Myxofibrosarcoma is also known as a myxoid variant of malignant fibrous histiocytoma, and this is one of the most common sarcomas in the extremities of elderly people; it is characterized by a high frequency of local recurrence. We herein report on a case of myxofibrosarcoma of the bladder. A 58-year-old man was referred to our hospital because of microscopic hematuria. Computed tomography(CT) and intravenous pyelography(IVP) showed a 12x7cm sized bladder mass in the pelvic cavity. The cystoscopic finding shows a protruding mass at the dome and posterior wall of the bladder. After exploratory laparotomy and tissue frozen biopsy were done, radical cystectomy and uretero-ileo-cutaneous anastomosis were then carried out. The diagnosis of the tumor was confirmed by histopathological examination. The myxofibrosarcoma of the bladder was completely excised, and there was no evidence of recurrence after 10 months of follow-up.

We herein report a case of ectopic prostate tissue involving the posterior wall of the bladder. A 33-year-old man was referred to our hospital because of a bladder tumor that was incidentally discovered on abdominal ultrasonography (US). US and computed tomography (CT) showed a 1.5x2.0cm sized tumor in the posterior wall of the bladder. Cystoscopic examination revealed a sessile tumor, covered with normal bladder mucosa in the posterior wall of the bladder. Transurethral resection of the bladder tumor was carried out and the origin of the tissue was confirmed by immunohistochemical staining for prostate specific antigen. The histopathological examination revealed benign prostate tissue that was situated ectopically.
