The back pain is increasingly becoming a major problem in the elderly people. The cause of back pain in the elderly patient is quite different from in the young subject. And relationship of the occurrence of osteoporosis with the incidence of fractures in general is currently regarded as a major factor. The authors performed clinical observation on 194 elderly patients who were treated for back pain during 5 years period from April, 1983 to April, 1988 at the Department of Orthopaedic Surgery, Severance Hospital and relationship between osteoporosis and compression fracture of spine was reviewed. The results were as follows : l. Among the 194 cases of back pain(28.3% of total admission cases), whose age were over 50: 142 cases were female and 52 cases were male, being more common in female. 2. Most common cause of back pain was the compression fracture of spine : 86 cases(44.3 %). Osteoporosis was associated with 66 cases(76.7%) out of 86 cases. 3. The number of compression fracture in same patient was more frequent in osteoporotic patient and thoracolumber junction (T12, Ll) was the major site of fracture (45.6%). Compression fracture of spine caused by osteoporosis occured at multiple level in 60.6%. 4. Twenty three cases(34.8%) of compression fracture of spine with osteoporosis were found to have previous history of fractures of spine and/or extremities by radiological examination. Regarding this results, compression fractures of spine was not infrequent cause of back pain in the elderly. It was thought that re-fracture of spine should be prevented by vigorous approach against osteoporosis along with the treatment of presenting fracture in these patients.

Since 1952, Ilizarov external fixator has been developed and used for more than 30 years in Russia and world-wide interest on it has been prevalent during last 2-3 years. The fixation of the tension applied thin wires to the metal frame resist flexional and translational deformity just like other extenal fixators. But, it allows cyclic axial micro-motion at the fracture site without loss of reduction so that it can provide good environment for the fracture healing biologically and biomechanically. Another advantage of Ilizarov external fixator is that it permits mobilization of the adjacent joints and weight bearing of the fractured limb during the application of it and shortens the duration of administration. Since 1988, We applied the Ilizarov external fixator for the treatment of diffcult tibial fractures (open comminuted, segmented and comminuted fractures, nonunion, maunion) and obtained good results in 7 cases. So we report our results even if we had limited cases and experiences.

4.Improvement of catheter-related outcomes after application of tunneled cuffed hemodialysis catheter insertion without fluoroscopy
Yeungnam University Journal of Medicine 2020;37(3):186-193
Background:
Non-tunneled catheters (NTCs) are used for hemodialysis (HD) in many centers in which fluoroscopy is not easily accessed despite high complication rates and conditions requiring long-term HD. Therefore, here we aimed to evaluate the superiority of catheter-related outcomes after the application of tunneled cuffed catheter (TCC) without fluoroscopy versus unconditioned NTC insertion.
Methods:
We divided the participants into two phases: those receiving NTCs between March 2010 and February 2011 (phase I), and those receiving TCCs or NTCs between March 2011 and February 2012 (phase II). Catheter survival, nurse satisfaction, and reasons for catheter removal were analyzed.
Results:
Two hundred and sixty patients in phase I and 300 patients in phase II were enrolled in this study. The success rate of TCC insertion was 99.2%. The catheter survival rate in phase I was 65.5% at 1 month, while that in phase II was 74.9% at 1 month (p=0.023). We compared catheter survival between TCCs and NTCs for all periods regardless of phase. The TCC survival rate was higher than the NTC survival rate (p<0.001). Catheter-associated problems led to catheter removal in 97 patients (26.6%) in phase I and 68 patients (18.5%) in phase II (p=0.009). Among 14 HD nurses, all reported being satisfied with manipulation during pre-/post-HD, manupulation during HD, and overall. Eleven HD nurses (78.6%) reported being satisfied with the workload.
Conclusion
Compared with unconditional NTC insertion for HD, TCC insertion without fluoroscopy improved the overall catheter survival and nurse satisfaction rates.

Further studies are needed to identify whether muscle mass, muscle strength, or sarcopenia is the best indicator of survival in patients undergoing peritoneal dialysis (PD). We aimed to compare the association of sarcopenia and its components with survival in patients undergoing PD. Methods: We identified all patients with PD (n = 199). We routinely recommended handgrip strength (HGS) and lean mass measurements using dual energy X-ray absorptiometry in all patients with PD. Sarcopenia was defined using cutoff values from the Asian Working Group for Sarcopenia. We evaluated the patient and technique survival rates. Results: The number of patients with low HGS was 95 (47.7%). The median follow-up interval was 17 months (interquartile range, 13–21 months). Kaplan-Meier curve analysis showed that patients with low HGS or sarcopenia had poorer patient and technique survival compared with patients with normal HGS or without sarcopenia. Cox regression analysis showed that patients with low HGS had greater hazard ratios for patient death and technique failure compared with those with normal HGS. However, patients with low muscle mass were not significantly higher hazard ratios for patient death or technique failure compared with those with normal muscle mass. Patients with sarcopenia had significantly greater hazard ratios for patient death or technique failure than those without sarcopenia only in univariate analysis. Conclusion: The present study demonstrated that HGS may be superior to muscle mass or sarcopenia for predicting patient or technique survival in patients undergoing PD.

PURPOSE: Return of spontaneous circulation (ROSC) is closely related to a favorable treatment outcome in out-of-hospital cardiac arrest and is also a reliable treatment target in clinical trials. The aim of this study is the identification of major factors affecting field ROSC by analyzing the updated data encompassing the pre-hospital treatment processes. METHODS: This is a retrospective review of cardiopulmonary resuscitation (CPR) cases performed by 119 rescuers before hospital arrival from January 2012 to December 2014 in one province. Cases with traumatic cardiac arrest, unnecessary CPR, arrest occurred during transport, under age 14 years, and incomplete medical records were excluded. RESULTS: Of 1,832 patients enrolled in the study, ROSC was achieved in 99 cases (5.4%). Among them, 50 (50.5%) had ROSC at the event field and others achieved ROSC during the transport process, respectively. Total cases were divided into two groups based on ROSC before arrival at the hospital. Age, underlying cardiovascular illnesses, the event place, presence of a witness, bystander CPR, application of an automated external defibrillator (AED), the initial shockable rhythm, defibrillation, advanced airway, hydration, the arrival time of rescuer CPR, application time of AED, and defibrillation showed significant statistical differences. In multivariate analysis, age, defibrilOf 1,832 patients enrolled in the study, ROSC was achieved in 99 cases (5.4%). Among them, 50 (50.5%) had ROSC at the event field and others achieved ROSC during the transport process, respectively. Total cases were divided into two groups based on ROSC before arrival at the hospital. Age, underlying cardiovascular illnesses, the event place, presence of a witness, bystander CPR, application of an automated external defibrillator (AED), the initial shockable rhythm, defibrillation, advanced airway, hydration, the arrival time of rescuer CPR, application time of AED, and defibrillation showed significant statistical differences. In multivariate analysis, age, defibrillation, hydration, bystander CPR, and the call-to-rescuer CPR interval appeared to be correlated with field ROSC. CONCLUSION: To improve the survival rate through field ROSC, a public campaign to improve bystander CPR, prompt recognition of cardiac arrest, and rapid application of pre-hospital treatment and political support of the public institution are mandatory.

B-lineage non-Hodgkin lymphoma may aberrantly coexpress T-cell markers. In general population, however, cases of diffuse large B-cell lymphomas with CD3 co-expression are rare because the CD3 marker is the most lineage specific T-cell antigen. We report a case of CD3 coexpressed diffuse large B-cell lymphoma in a 47-year-old male patient presented with dyspepsia who had transplanted a kidney 17 years ago. An esophagogastroduodenoscopy displayed an ulcerated mass in the gastric antrum. The pathology of the mass was monomorphic post-transplant lymphoproliferative disorder - specifically, CD20- and CD3-positive diffuse large B-cell lymphoma. Resection of the mass and postop chemotherapy were performed. A follow-up computerized tomography showed disapperance of tumor. No recurrence was observed until 7 month after treatment. Nevertheless, the patient's renal function gradually aggrevated and progressed to end stage renal disease. As far as we know, this is the first case of diffuse large B-cell lymphoma with CD3 coexpression after kidney transplant.

The basic graph layout technique, one of many visualization techniques, deals with the problem of positioning vertices in a way to maximize some measure of desirability in a graph. The technique is becoming critically important for further development of the field of systems biology. However, applying the appropriate automatic graph layout techniques to the genomic scale flow of metabolism requires an understanding of the characteristics and patterns of duplicate and shared vertices, which is crucial for bioinformatics software developers. In this paper, we provide the results of parsing KEGG XML files from a graph-theoretical perspective, for future research in the area of automatic layout techniques in biological pathway domains.

BACKGROUND/AIMS: The aim of this study is to measure the difference of ionized calcium between heparinized whole blood and serum. METHODS: We recruited 107 maintenance hemodialysis (HD) patients from our hospital HD unit. The clinical and laboratory data included ionized calcium in serum and in whole blood (reference, 4.07 to 5.17 mg/dL). RESULTS: The level of ionized calcium in serum was higher than that in whole blood (p < 0.001). Bland-Altman analysis showed that difference for ionized calcium was 0.5027. For the difference, the nonstandardized beta was -0.4389 (p < 0.001) and the intercept was 2.2418 (p < 0.001). There was a significant difference in the distribution of categories of ionized calcium level between two methods (kappa, 0.279; p < 0.001). CONCLUSIONS: This study demonstrates that whole blood ionized calcium is underestimated compared with serum ionized calcium. Positive difference increases as whole blood ionized calcium decreases. Therefore, significant hypocalcemia in whole blood ionized calcium should be verified by serum ionized calcium.
