The authors developed a computerized documentation system to record and store all the data pertaining to an endoscopic examination of the upper digestive tract. The system was programmed using the database management system Clipper Version 5.01. It is easy and convenient to use due to advanced deaign of input screen using menu bars and pull down menu and windows. The system was designed to permit the easy storage and retrieval of data by personnel who lack computer skills and who may only have limited typing ability. Today this system has been in daily use for 1 year at the endoscopic units of 8 different branch hospitals of Catholic university,medical college. Overall the experience in these centers has been positive, with excelient or good participation. Characteristics of this system are a menu-driven system, data input by predefined list, instantaneous report generation, on line access to previous examination, late entry of yathologic regerts. and record retrieval, listing according to different criteria. For the description of endoscopic findings and diagnosis, structured input is maintained. All of the findings are chosen from predefined list using pop-up screen and also free text typing is allowed. Therefore time effort was not increased compared to conventional documentation. Structured input and the resulting categorical data affer several advantages.

Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). Conclusions Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

Objective: Personal mobility vehicles (PMV) have been used widely as a means of replacing bicycles in recent yearsbecause of their convenience and high economic efficiency. On the other hand, accidents related to PMV are alsoincreasing, but there have been few studies in this area. This study examined the factors that increase the severity ofdamage and determine the characteristics of the PMV compared to the accidents on a bicycle. Methods: Retrospective observational studies were performed. The variables related to the accident were collected andanalyzed for patients who visited the emergency room due to a PMV and bicycle accident. Multivariate logistic regressionanalysis was used to determine the factors affecting the severity of the patients. The odds ratios were calculated andcompared between injuries related to PMV and bicycles. Results: A total of 1,124 patients (bicycles 1,017, PMV 107) were enrolled in this study. In multivariate regression analysis,the severity of PMV was higher (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.06-2.83) than that of a bicycle.The factors affecting the severity of the patients were age (OR, 1.02, 95% CI, 1.01-1.03), alcohol use (OR, 1,70; 95% CI,1.04-2.70), ambulance transport (OR, 2.46; 95% CI, 1.78-3.40), and wearing a helmet (OR, 2.06; 95% CI, 1.36-3.13). Conclusion PMV showed higher severity of damage than a bicycle. The PMV, which is a new transportation means, isinsufficient for the prevention of safety compared to bicycles where driving regulations and wearing protective equipmentare common. Additional studies on the precise mechanisms of injury and damage are expected to prevent accidents andreduce their severity.

Rituximab, a chimeric monoclonal antibody directed against CD20, has become a part of the standard therapy for patients with non-Hodgkin's lymphoma either in combination with other drugs or as a single agent. The CD20 antigen is expressed on 95% of B-cell lymphoma cells and normal B-cells but, is not found on precursor B-cells or stem cells. Rituximab is now approved for patients with diffuse large B-cell lymphoma when combined with standard CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone) or patients with follicular lymphoma who have failed first line chemotherapy. The monoclonal antibody is generally well tolerated. Most of the adverse events are infusion-associated, mild to moderate non-hematological toxicities. Severe respiratory adverse events have been infrequent. Here, we report two patients with non-Hodgkin's lymphoma in whom interstitial pneumonitis developed with rituximab therapy.

PURPOSE: To evaluate the clinical and radiological results of intramedullary fixation using Kirschner wires (K-wires) for the treatment of unstable forearm fractures in children. MATERIALS AND METHODS: Forty-three children who underwent intramedullary fixation using K-wires for the treatment of a forearm bone fracture were evaluated. The rodiological results were based on the time to union and angular deformity at last follow-up. The clinical results were analyzed according to Price criteria. RESULTS: Average union time was 6.9 weeks. Preoperatively, average angular deformity of radius is 11.4 degrees in anteroposterior (AP) view and 15.3 degrees in lateral view. In case of the ulna, arerage angular deformity was 8.3 degrees in AP view and 12.7 degrees in lateral view. At last follow up, average angular deformity of radius was 1.5 degrees in AP view and 1.6 degrees in lateral view. In case of the ulna, arerage angular deformity was 1.3 degrees in AP view and 2.5 degrees in lateral view. According to the criteria of Price et al., 42 patients (97%) were excellent and one patient (3%) was good. No specific complication was observed. CONCLUSION: An intramedullary fixation using K-wires is an attractive treatment option for unstable forearm fractures in children in terms of safety, excellent cosmesis, short hospitalization, easy hardware removal, and providing excellent radiological and clinical results.

Bacillus cereus causes two types of gastrointestinal diseases: emesis and diarrhea. It produces one emetic toxin and nine different enterotoxins. In March 2008, eight of a family became sick after eating slices of raw fish. We isolated emetic toxin producing B. cereus from the stools of 6 patients and 2 subclincal humans. In this study, the presence of enterotoxin genes, such as those of haemolysin BL (Hbl), nonhemolytic enterotoxin (Nhe), B. cereus enterotoxin T (BceT), enterotoxin FM (EntFM), cytotoxin K (cytK) and cereulide were assayed by polymerase chain reaction (PCR) methods. Their enterotoxin activities were assayed using the BCET- RPLA, Tecra ELISA kit and Hep-2 vacuole activity. Bacterial isolates were subtyped by pulsed-field gel electrophoresis (PFGE). This study demonstrates the emetic toxin-producing stains of B. cereus in clinical specimens, for the first time in the Republic of Korea.

PURPOSE: Endothelial dysfunction is an event in the atherosclerotic process usually considered reversible at its early stage. Early detection, therefor, may improve the prognosis in the cardiovascular disease. The aim of this study was to investigate the vascular function in hemodialysis (HD) patients and to explore its relation to other various parameters with a specific emphasis on systemic inflammatory reaction (SIR), nutritional status and the presence of ischemic heart disease (IHD). METHODS: Flow-mediated endothelium-dependent vasodilatation (FMD) was measured, using Doppler sonogram, in 37 stable HD patients, 11 healthy people and 24 hypertensive controls. Nitroglycerine- induced endothelium-independent vasodilatation (EIV) and peak reaction time (PT) of each FMD and EIV were also measured. RESULTS: FMD in HD patients was decreased compared to healthy group whereas it was comparable in HD patients and hypertensive control. EIV in HD patients was significantly decreased compared to healthy and hypertensive controls. PT of each FMD and EIV was significantly delayed in HD patients. Each FMD and EIV showed a negative correlation with serum hsCRP level, but no significant correlations of FMD with other parameters were noted. Both FMD and EIV were further decreased in HD patients with IHD than non-IHD group. CONCLUSION: Our study confirmed a characteristic pattern of vascular dysfunction in HD patients: the impaired endothelial and smooth muscle function with a delayed reaction time. Importantly, SIR was one of the important factors determining vascular dysfunction in HD patients. Further studies will be necessary to define the causative role of SIR on endothelial dysfunction and the effect of inflammation- modulating therapy.

BACKGROUND: Hypertonic saline (HS) injections for decompressive neuroplasty (DN) can cause pain. We assessed whether a continuous infusion of HS through an infusion pump would reduce injection-related pain compared with repeated bolus administrations. METHODS: Fifty patients scheduled for DN were randomized to either the bolus injection or the continuous infusion group. After appropriately placing the epidural catheter, 4 mL of 5% NaCl was injected as four boluses of 1 mL each at 15-minute intervals or infused over 1 hour using an infusion pump. The severity of pain induced by HS injection, as measured by the 11-point numerical rating scale (NRS), was the primary outcome. The severity of low back or lower extremity pain, as measured by the 11-point NRS and Oswestry Disability Index (ODI), 3 months following the procedure, was the secondary outcome. RESULTS: Data from 21 patients in the bolus group and 23 in the continuous infusion group were analyzed. No statistically significant difference in injection-related pain was identified between the two groups during the initial HS administration (P = 0.846). However, there was a statistically significant reduction in injection-related pain in the continuous infusion group compared to the bolus injection group from the second assessment onwards (P = 0.001, < 0.001, and < 0.001, respectively). No significant between-group differences in the NRS and ODI scores 3 months post-procedure were noted (P = 0.614 and 0.949, respectively). CONCLUSIONS: Our study suggests that administering HS through a continuous infusion is a useful modality for reducing HS injection-related pain during DN.

A variety of benzylidenethiazole analogs have been demonstrated to inhibit 5-lipoxygenase (5-LOX). Here we report the anti-atherogenic potential of 5-(4-hydroxy-2,3,5-trimethylbenzylidene) thiazolidin-2,4-dione (HMB-TZD), a benzylidenethiazole analog, and its potential mechanism of action in LDL receptor-deficient (Ldlr-/-) mice. HMB-TZD Treatment reduced leukotriene B4 (LTB4) production significantly in RAW264.7 macrophages and SVEC4-10 endothelial cells. Macrophages or endothelial cells pre-incubated with HMB-TZD for 2 h and then stimulated with lipopolysaccharide or tumor necrosis factor-alpha (TNF-alpha) displayed reduced cytokine production. Also, HMB-TZD reduced cell migration and adhesion in accordance with decreased proinflammatory molecule production in vitro and ex vivo. HMB-TZD treatment of 8-week-old male Ldlr-/- mice resulted in significantly reduced atherosclerotic lesions without a change to plasma lipid profiles. Moreover, aortic expression of pro-atherogenic molecules involved in the recruitment of monocytes to the aortic wall, including TNF-alpha , MCP-1, and VCAM-1, was downregulated. HMB-TZD also reduced macrophage infiltration into atherosclerotic lesions. In conclusion, HMB-TZD ameliorates atherosclerotic lesion formation possibly by reducing the expression of proinflammatory molecules and monocyte/macrophage recruitment to the lesion. These results suggest that HMB-TZD, and benzylidenethiazole analogs in general, may have therapeutic potential as treatments for atherosclerosis.

PURPOSE: Cardiac troponin T (cTnT), a useful marker for diagnosing acute myocardial infarction (AMI) in the general population, is significantly higher than the usual cut-off value in many end-stage renal disease (ESRD) patients without clinically apparent evidence of AMI. The aim of this study was to evaluate the clinical usefulness of cTnT in ESRD patients with acute coronary syndrome (ACS). MATERIALS AND METHODS: Two hundred eighty-four ESRD patients with ACS were enrolled between March 2002 and February 2008. These patients were followed until death or June 2009. Medical records were reviewed retrospectively. The cut-off value of cTnT for AMI was evaluated using a receiver operating characteristic (ROC) curve. We calculated Kaplan-Meier survival curves, and potential outcome predictors were determined by Cox proportional hazard analysis. RESULTS: AMIs were diagnosed in 40 patients (14.1%). The area under the curve was 0.98 in the ROC curve (p<0.001; 95% CI, 0.95-1.00). The summation of sensitivity and specificity was highest at the initial cTnT value of 0.35 ng/mL (sensitivity, 0.95; specificity, 0.97). Survival analysis showed a statistically significant difference in all-cause and cardiovascular mortalities for the group with an initial cTnT > or =0.35 ng/mL compared to the other groups. Initial serum cTnT concentration was an independent predictor for mortality. CONCLUSION: Because ESRD patients with an initial cTnT concentration > or =0.35 ng/mL have a poor prognosis, it is suggested that urgent diagnosis and treatment be indicated in dialysis patients with ACS when the initial cTnT levels are > or =0.35 ng/mL.
