In modem medical industries as in others, it has been emphasized by many experts such as Dr. Mayer and Dr. Donabedean that there should be quality assurance activities applying statistical knowledges in the processes of medical management and medical staff themselves for the better medical care and customer satisfaction. Three of our quality assurance programs for the purpose of shortening the treatment time In the department of emergency medicine in Keimyung University, Dong-San Medical Center had been carried out during the period of June 94 through December 95. Our methodology was mainly the process emphasized ; finding the causes of delaying factors in various processes related to the works of nurses, doctors, laboratory services, radiology services etc. in the emergency room, holding various meetings among the related groups with genuine discussions, notifying the new results in each step, encouraging the positive ones and also applying the new leadership technics. During the period of June 94 through December 95(for 1.5 years), the average E.R. patient treatment time from registrations to dispositions had been reduced by about 2 hours (from 5 hours 3 minutes to 2 hours 5 minutes) and its variations among the different specialities had been narrowed down to significant degree (p<0.05) revealing the preprogram base line standard deviation of 2.43 to 1.28 in post program through continuous quality assurance programs. It was also noted that the successful results of Q/A program have been closely related to the fact that the process should be designed and redesigned repeatly as needed and that all the participants related were actively involved in the planning and redesigning processes.

A microemulsion formulation of cyclosporine (CsE) is more bioavailable than conventional cyclosporine (CsA) in renal transplants. Because the risk of acute and chronic rejection is related inversely to cyclosporine bioavalability and cyclosporine has a low therapeutic window, these benefits of CsE with an improved pharmacokinetic profile on clinical efficacy are also of interest. To assess the long-term safety and tolerability of CsE, this comparable study was performed. One hundred thirty one primary living donor renal recipients were included in this study. They were divided two groups in the CsE group (N=50) and CsA group (N=81) who had been received either CsE or CsA as a main immunosuppressant since their transplantation for two years. There were no differences between two groups in initial dose at that time of transplantation, target trough level, strategies of anti-rejection therapy. Acute rejections occurred less frequently in CsE group than CsA group (9/50 vs. 28/81, p=0.041). No significant differences were noted in incidence of chronic rejection, graft loss, drug-associated com plications such as hypertension, diabetes mellitus, infection and survival rates of grafts and patients. Renal function, as measured by serum creatinine levels was comparable over time in both groups. The mean daily doses of CsE were higher than CsA group since post-transplant six months, but, no significant differences in trough levels between the two grups. There were marked decreases in standard deviation of daily doses and trough level those meant inter-individual variations in CsE group compared to those of CsA group. In conclusion, despite the more predictable and stabilized pharmacokinetic benefits in CsE group, no significant increases in the incidence of drug-associated adverse effects were observed within post-transplant two years. The safety, tolerability, efficacy of CsE and CsA were comparable.

Mycophenolate mofetil (MMF) is being widely used as a maintenance imunosuppressive therapy in renal transplant patients. Myelotoxicity and gastrointestinal symptoms are the well-known adverse effects of this immunosuppressant. However, there areexistonly two reports on oral ulceration associtated with MMF. Although oral ulcerations are not life-threatening, they may seriously affect the quality of life. We report ourthe experience of a case of a 57-year-old female patient with painful oral mucosal ulcerations that improved following MMF discontinuation.

Journal of Korean Society of Spine Surgery 2017;24(2):72-79
STUDY DESIGN: Prospective study. OBJECTIVES: To assess the correlation between symptom improvement and spinal canal dimensions in patients who underwent selective nerve root block for lumbar spinal stenosis. SUMMARY OF LITERATURE REVIEW: When the canal size is relatively small, the pressure on the nerve root increases. Decompressive surgery relieves more pain in such patients. MATERIALS AND METHODS: From July 2009 to March 2011, 141 patients received selective nerve root block for 1-level central lumbar spinal stenosis in our hospital. We evaluated the patients using a visual analog scale (VAS) before the procedure and 1 hour, 1 month, and 3 months following the procedure. We measured the spinal canal using magnetic resonance imaging. RESULTS: There was no significant correlation between spinal canal dimensions and the pre-procedure VAS. We divided the patients into 3 groups using the average and the standard deviation of the patients' spinal canal dimensions (<73.1 mm², 73.1-172.5 mm², >172.5 mm²) (p<0.01). One hour after the procedure, the VAS scores changed by 1.43±1.8, 1.62±1.7, and 1.53±1.5, respectively, with no significant differences among the 3 groups. However there were significant differences in the VAS changes 1 month and 3 months following the procedure, with results of 2.39±1.7 and 1.39±1.5, 4.65±2.1 and 4.28±2.3, and 4.97±2.2 and 6.83±1.9 (p<0.01), respectively. CONCLUSIONS: The smaller the area of the spinal canal, the less likely symptoms were to improve after selective nerve root block. The results of this study will help predict the effects of selective nerve root block in spinal stenosis patients.

PURPOSE: The umbilical cord blood has been considered as an alternative source of hematopoietic stem cells for transplantation. The CD34+ is known as a common stem cell antigen and the CD34+ CD38- immunophenotype reportedly defines a primitive subpopulation of progenitor cells. In this study the frequency of CD34+ and CD34+ CD38- hematopoietic stem/progenitor cells in placental/cord blood (UCB), and adult peripheral blood (PB) were determined. METHODS: Between July and September 1998, 27 collections of UCB were performed at the obstetric units of Hanyang University Hospital. Fifteen adult PB samples were also obtained for control. RESULTS: The frequency of total CD34+ cells in UCB was higher (1.13+/-0.58% vs 0.46+/-0.30%, P=0.0002) than PB and the frequency of CD34+ CD38- cells in UCB was also greater (0.02+/-0.02 vs 0.01+/-0.01, P=0.035) than PB. The majority of UCB- and PB-derived CD34+ cells expressed CD38- antigen (98.22+/-2.11% in UCB and 97.85+/-2.56% in PB). The frequency of CD38- expression by UCB derived CD34+ cells was slightly higher (not statistically significant) than that by PB derived CD34+ cells. The frequency of CD34+ cells was increased linearly with birth weight (r=0.413). CONCLUSION: These results suggest that UCB could be a useful source of highly primitive hematopoietic stem cells for marrow reconstitution after bone marrow ablation.

BACKGROUND:This study estimated the number of self-reported intervertebral disc disorders in Korean adults from a representative sample. METHODS:We analyzed the data from the third Korea National Health and Nutrition Examination Survey conducted in 2005 using surveyfreq procedure of the SAS statistical package and estimated the number of Korean adults who reported that they experienced intervertebral disc disorders during their lifetime (lifetime patients) and those who reported that they experienced intervertebral disc disorders lasting for three or more months during the past year or were suffering from intervertebral disc disorders at the time of survey (one-year patients). RESULTS:It was estimated that there were 2,653,230 (proportion, 7.4%; 95% CI, 2,490,624-2,815,835) self-reported lifetime patients and 2,250,850 (6.3%; 2,102,714-2,398,986) self-reported one-year patients among 35,719,293 Korean adults aged 20?89 years in 2005. CONCLUSIONS:Further efforts to investigate exact number of Korean adults with intervertebral disc disorders and improve treatment outcomes of intervertebral disc disorders are needed.
