The transpedicular screw fixation is known to be capable of providing more secure correctional, force and rigid fixation to the spine. But it is often accompanied by various complications, including stress shield effects, loosening in osteoporotic spine, pseudoarthrosis, hardware problems and long-term change in motion behaviors at the adjacent motion segment and etc. The purpose of this study is to compare the flexible and rigid rods system in terms of complications and problems for various degenerative lumbar diseases. From September 1991 to November 1994, 41 patients were operated with the flexible rods system (group A) and 39 patients with the rigid rods system (group B). They were followed up for more than 4 years. The flexible rods system was composed of 41 cases of Wiltse system and the rigid rods system was composed of 29 cases of Diapason, 8 cases of TSRH and 2 cases of CD instrument. The resuits of the study were as follows: 1. By standard Cobb lateral measurement, 7 cases in group A and 10 cases in group B showed significant loss of sagittal angle (>4), post-operatively. 2. Hardware failure was noted in 7 cases in group A and 10 cases in group B. In group A, rod bending was seen in 4 cases, rod breakage in 2 and screw loosening in one. In group B, screw loosening was observed in 5 and screw-rod locking mechanism failure in 5 cases. 3. In spondylolisthesis patients, 10 cases in group A and 14 in group B, there was no statistically significant differences between the two groups in the reduction rate immediately after surgery and loss of reduction at the last follow up. 4. Clinical results were good to excellent in 85.4% of patients in group A and 82.1% of group B. No statistically significant differences between the two groups were found, 5. No statistically significant differences between the two groups were found with respect to degenerative changes at the adjacent motion segment to the fused level and pseudoarthrosis.

Though the occurrence of multiple primary malignant tumor is a rare finding but the reported cases of it has increased in recent years. We collected multiple primary cancer of different organ, tissue and the multicentric origin of bilaterally paired organs. This paper reports 6 cases of multiple primary malignant tumors which were experienced at Yeungnam university hospital in Taegu during the past 2 years with review of journals. The results were as follows. 1. The incidence of multiple primary cancer was 0.31% for 2 years (1987-1988). 2. The ratio between male and female was 1:1 and mean age of incidence was 54.1 years. 3. The ratio between synchronous and metachronous (interval more than 6 months) was 1:1. 4. The time interval between first and second cancer was average 2.7 years in metachronous cases. 5. The most frequent involved organ was stomach, breast and colon in order of frequency. 6. The incidence of familial cancer associations was found in one out of 6 cases. 7. The test of DNCB, multitest CMI and ratio of T4 to T8 were performed in 4 cases but there was no definitive evidence of abnormality. We concluded that every effort should be made to discover the presence of synchronous malignancies in the patients who are being treated for a known tumor, and also special care should be given to detect new metachronous lesions is required.

BACKGROUND: The laparoscopic cholecystectomy (LC) has been accepted as the procedure of choice for chronic cholecystitis. However in cases of acute cholecystitis, the safety and the efficacy of LC has not been fully determined. Thus we performed this study to assess the clinical outcomes of a LC for acute cholecystitis to evaluate it's efficacy and safety. METHODS: The authors retrospectively analyzed 1,164 LCs performed in Yeungnam University Hospital from May 1991 to March 1996. Among the 1,164 LCs, 118 were performed for acute cholecystitis and 1,046 were performed for chronic cholecystitis. The authors compared the mean operation time, the conversion rate to an open cholecystectomy (OC), the reasons for conversion, the complication rate, the postoperative hospital stay, and the postoperative use of analgesics between the patients with acute cholecystitis and the patients with chronic cholecystitis. RESULTS: In the 1046 patients with chronic cholecystitis, the mean operation time was 55.9 minutes, the conversion rate to an OC was 2.7%, the complication rate was 4.0%, the mean postoperative hospital stay was 3.3 days, and analgesics were used in 48% of the patients. However in the 118 patients with acute cholecystitis, the mean operation time was 65 minutes, the conversion rate to an OC was 11.8%, the complication rate was 16.9%, the mean hospital stay was 4.4 days, and analgesics were used in the 60% of the patients. Also the authors found that the longer duration of preoperative symptoms and an advanced state of inflammation (e.g., GB empyema or gangrenous changes) were the two most common causes of conversion to an OC in the case of acute cholecystitis. Although all the analyzed parameters (especially, the conversion rate and the complication rate) were higher in the patients with acute cholecystitis than they were in the patients with chronic cholecystitis, a LC for acute cholecystitis seems to be acceptable because there were no mortalities and there were no life threatening complications. CONCLUSIONS: From, the aspects of safety and efficacy, a LC can be performed in most patients with acute cholecystitis. However, it should be remembered that the prolonged duration of symptoms prior to a LC increases the conversion rate to O.C. and if we confront the advanced cholecystitis (GB empyem or gangrenous change) with difficult Calot's triangle during a L.C., early conversion to an OC should be considered.

7.Factors Associated with Job-related Injuries among Cleaners in Hospitals.
Korean Journal of Occupational Health Nursing 2015;24(3):214-223
PURPOSE: This study was conducted to provide basic data for development of health care programs for cleaners working in hospitals by analyzing job-related injuries among them and related factors. METHODS: The study surveyed cleaners working in 6 general hospitals in D metropolitan city. The questionnaire was structurally designed to include items about job-related injuries, working conditions, health related characteristics. For the analysis of the collected data, the SPSS/WIN 21.0 software was used, and t-test, ANOVA, correlation analysis, and regression analysis were conducted. RESULTS: Factors that affect health damages were gender and income levels. Inadequate safety facilities and equipment, noise, and income levels were found to be the factors affecting accident injuries. CONCLUSION: In order to reduce the job-related injuries, efforts need to be made to improve working conditions to deal with inadequate safety facilities and equipment and control noise. To fulfill this need, not only employers of cleaners but also hospitals in which they work should make efforts to educate those cleaners who have little knowledge of health and medical care, and improve their working conditions.

OBJECTIVES: To evaluate the urinary concentrations of hydroxyridinium crosslinks of collagen in patients with osteoarthritis(OA) or rheumatoid arthritis(RA), and to compare its clinical correlation with the classic indices of the disease activity of RA. METHODS: Concentrations of urinary pyridinoline (Pyd) and deoxypyridinoline(Dpd) were measured in urinary samples collected from 18 control patients, 35 patients with OA, 45 patients with RA by competitive enzyme immunoassay using microplate coated with monoclonal antibody. RESULTS: 1) Mean urinary concentrations of Pyd in OA patients were 33.5nmol/mmol creatinine, in RA patients were 50.0nmol/mmol creatinine which were higher than the values in controls (25.1 nmol/mmol creatinine). Also, mean concentrations of Dpd in OA patients were 9.2nmol/mmol creatinine, in RA patients were 10.1nmol/mmol creatinine which were higher than the values in controls(5.6nmol/mmol creatinine)(p<0.01). 2) Mean urinary concentration of Pyd was 50.0 nmol/mmol creatinine in RA patients, which was significantly higher than the values in OA(33.5 nnmol/mmol creatinine)(p<0.05), but the mean Dpd concentratians were not significantly different between the two groups. 3) The concentrations of urinary Pyd in RA patients was significantly correlated with the biologic markers indicating inflammatory activity such as ESR(r=0.68, p<0.001), CRP(r=0.72, p<0.001) and the number of tender joint(r=0.66, p<0.01) CONCLUSION: Urinary concentrations of Pyd and Dpd were significantly higher in OA and RA patients than in controls, Especially urinary Pyd concentrations were significantly increased in RA patients than in OA patients, and strongly correlated with disease activity index of rheumatoid arthritis. The mean Dpd concentration, bone specific analogue, in RA patients was not significantly different from that of OA patients and it was not correlated with disease activity index Thus measurement of urinary Pyd might provide a sensitive, noninvasive biochemical marker for studying activity of RA.

9.Relationship between Types of Role Conflict and Turnover Intention in Nurses Working at Rehabilitation Hospitals
Korean Journal of Rehabilitation Nursing 2019;22(2):142-151
PURPOSE:
Nurses working at rehabilitation hospitals play an important role in interdisciplinary teams. However, conflicts with others within the teams are common. This study (1) explored the frequency and seriousness of role conflicts and determined the relationship between turnover intention and type of role conflict among nurses in rehabilitation hospitals and (2) investigated differences in turnover intention by the type of role conflict.
METHODS:
Data were collected from 110 nurses in two rehabilitation hospitals. A survey was performed to measure role conflicts including conflicts regarding nursing practice, and conflicts with staff nurses, patients/guardians, staffs in other departments, and doctors. Also, nurses' turnover intentions were evaluated. Data were analyzed using descriptive statistics and cluster analysis.
RESULTS:
The most common and serious conflicts were developed with patients/guardians, followed by conflicts related to nursing practice. Conflicts in relation to nurses' roles were classified into four categories: ‘High conflict type’, ‘High frequency of conflict type’, ‘High seriousness of conflict type’, and ‘Low conflict type’. The level of turnover intention was increased in this order.
CONCLUSION
To decrease rehabilitation nurses' intentions to leave a hospital, it is important to reduce role conflicts by providing tailored interventions for each type of conflict and to improve the organizational interrelationship process.

Objectives:
Dental caries and periodontal disease are infectious and chronic diseases. The aim of the study was to investigate the antimicrobial effect of mentha extracts against Streptococcus mutans (S. mutans ) and Porphyromonas gingivalis (P. gingivalis ).
Methods:
This activity of mentha extracts were confirmed by the disk diffusion test and minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and colony forming unit (CFU) assays.
Results:
S. mutans and P. gingivalis showed the highest antimicrobial activity within the inhibition zones. The antimicrobial activity was interrupted as the MIC and MBC of the herbal extracts against the two bacteria were 1 mg/ml and 10 mg/ml, respectively. The antimicrobial effect was determined by the CFU assay.
Conclusions
Mentha herb extract demonstrated potential antimicrobial activity against S. mutans and P. gingivalis that cause dental caries and periodontal disease.
