We retrospectively reviewed the MRI findings of 100 temporomandibular joints in 78 patients who had complained temporomandibular joint dysfunction. MRI findings were classified according to Wilke's staging criteria. And these findings were compared with arthrographic findings in 22 joints and surgical findings in 44 joints. According to Wilkes's staging. They were classified into 6 stages of abnormality: stage 0 (33 cases), stage I (19 cases), stage II (10 cases), stage III (18 cases), stage IV (6cases), stage V (14 cases). Among the 22 cases in which arthrography and MRI were done, both studies were well correlated in 10 joints. In 7 joints, MRI was superior to arthrography, which correctly demonstrated the meniscal displacement in 2 joints and . Meniscal deformity in 5 joints. In 5 joints, arthrography was superior to MR, which demonstrated the perforation (1 joint), adhesion (2 joint) and recapture of meniscus (2 joints). Compared with surgical findings, MRI correctly demonstrated the displacement of meniscus in all 44 joints. However, in case of the 10 meniscal perforation, MRI demonstrated the meniscal discontinuity in only 4 joints. Retrospective MR findings in 10 proven cases were the defect in posterior attachment in 4, far anterior meniscal displacement without recapture in 8m condylar spur in 4, and close bone to bone contact in 1. In conclusion, MRI as a primary Fiagnostic modality of temporomandibular joint derangment, is superior for the grading of displacement and deformity of meniscus but inferior for the evaluation of perforation, adhesion and recapture of meniscus to conventional arthrography. In case of the suspected meniscal perforation, arthrographic correlation is recommanded preoperatively.

We studied 21 neonates who required mechanical ventilation during study period in NICU OF Il Sin Christian Hospital with diagosis of prematurity, IRDS, pneumothorax and diaphragmatic hernia to evaluate the accuracy of pulse oximeter in predicting the arterial oxygen saturtion, hypoxia and hyperoxemia. We also studied whether the changes of birth weight, hematocrit, blood pressure and body temperature affect the accuracy of pulse oximeter. The results are 1) Linear regression analysis revealed a close correlation between in vivo pulse oximeter readings and in vitro SaO2 measurements in patients (Y=0.008X+12.34, r=0.946) 2) The changes of birth weight, hematocrit, blood pressure and body temperature did not affect the accuracy of pulse oximeter. 3) SpO2-PaO2 relationship was similar to the SsO2-PaO2 relationship. 4) When Nellcor N-100 pulse oximeter was setted at alarm limit 96% to avoid hyperoxemia, it identified 16 of 22 hyperoxemic instances (sensitivity 73%) and alarmed falsely in 48 of 92 nonhyperoxemic instances (specificity 59%).

PURPOSE: The purpose of this study is to evaluate the usefulness of fat suppression technique for MR imaging of the knee. MATERIALS AND METHODS: Twenty-eight knees of 26 patients were imaged at a 1. 5 T MR system. Sagittal and coronal T2-Weighted spin echo images (SET2) and sagittal fat suppression SET2(FSSE) were obtained in all cases. We used a chemical shift imaging method for fat suppression. We compared FSSE with SET2 in terms of the conspicuity of lesions of menisci, cruciate ligaments, cartilage, bone and soft tissue of the knee. RESULTS: Meniscal lesions were detected on FSSE and SET2 as well. FSSE depicted the lesion more conspicuously in 6 cases. For the depiction of ACL tear, SET2 was superior to FSSE in 5 cases. FSSE was better for the visualization of the normal structure of cartilage and it also depicted the cartilaginous lesions more conspicuously in 3 cases. Though bone bruise could be detected on both techniques, FSSE was better. CONCLUSION: FSSE could provide the improved delineation of menisci, cartilage, bone bruise and other soft tissues except the injuries of anterior cruciate ligament. Although FSSE is a reliable method, it can not replace SET2. It may be used as a complemental method in the imaging of the knee.

The purpose of this study was to identify how students majoring in nursing perceive cause of cancers and the effects of diet for preventing cancers. Data for the study were collected by 651 nursing students, who were registered in the second and third year in three technical colleges and third and fourth year in two universities. The research instruments included items on general characteristics of subjects, items about the degree of perception of the frequency of cancer onset and items on the perception of mortality, risk factors, preventive diets, knowledge, and high risk factor for cancer in specific body areas. The findings of this study are as follows : 1. Almost all subjects(92.8%) reported that the frequency of cancer onset increases and that it is 93.9% for people over 40. Degree of perception about cancer mortality was low at 33.0%. 2. As far as the perception of risk factors for cancer onset was concerned, smoking, stress, heredity, family history, and alcohol were rated high, over 80.0%. Risk factor in clouding, virus, hormones, pesticides were rated as low. 3. As to the perception of risk factor for body area as associated with diet salted and scorched food were rated at 44.5% for stomach cancer, alcohol, 50.4% for liver cancer, smoking, 72.8% for lung cancer, pregnancy times, 25.3%, and marriage age, 23.0% for uterine cancer, and no delivery experience, 40% for breast cancer. 4. The knowledge score for cancer was between 12 and 36, with a mean score of 26.75(SD=4.13). There was a statistically significant difference between experience in caring for cancer patients during clinical practice and knowledge score(t=3.09, p=.002).

PURPOSE: To identify perceived importance and performance frequency of nursing interventions with nursing activities of 5 nursing interventions from the physiological domains of NIC used in the home health care nursing. METHOD: Five nursing interventions in the physiological domain of NIC were selected based on the previous finding. Data were collected from 85 nurses working in 54 home health care centers between August and October, 2004 using mailing survey(return rates : 41.5%). The questionnaire consisted of 96 nursing activities in 5 interventions with definitions, asking perceived importance and performance frequency of them. RESULT: Skin surveillance was perceived as the most important(3.52+/-0.36) intervention and also performed most frequently(4.43+/-0.45). All the nursing activities in skin surveillance appeared to be used frequently, which was rated over 4 out of 5 point Likert, while only 4 nursing activities in exercise therapy: joint mobility did. Correlations between perceived importance and performance frequency of 5 interventions were all significant (r=0.591-0.718, p=0.000). CONCLUSION: Identifying the use of particular interventions and nursing activities will help nurses simplify documentations and to deliver better care to the patients in home health care nursing.

This study was conducted to compare the severity of cannulation pain in hemodialysis patients after topical application of EMLA cream and local injection of lidocaine and evaluated side effects and problems accompanied by the former. Twenty patients, who were on hemodialysis from September 1 to October 15, 1994 at the Kangnam St. Mary's Hospital, Catholic University Medical College, were divided into two groups of ten. To conduct a cross over study, two groups were placed on four repeated methods with lidocaine followed by four repeated methods with EMLA cream and vice versa, respectively, while the severity of cannulation pain was being measured according to a Visual Analogue Scale with each methods. The results are follows : 1) The scale of pain was recorded as 4.56+/-1.38 and 2.05+/-1.36 points for methods with lidocaine and EMLA cream, respectively, indicating the less severe pain with EMLA cream. 2) Local side effects such as itching(4 cases, 5.0%) and pallor(5 cases, 6.3%) were observed with methods with EMLA cream but disappeared before the completion of hemodialysis. 3) Problems associated with local lidocaine were pain at the injection of anesthetic (27 cases, 16.9%) and fear for needle insertion (6 cases, 3.8%). The most frequent problems with EMLS cream application were an inconvenience in use (11 cases, 6.9%) and tedious long pretreatment time (11 cases, 6.9%), those associated with inconvenience in cream applying procedures. 4) Twelve out of twenty patients(60.0%) responded with yes to a continued use of EMLA cream in spite of problems with cream application and economical difficulties in purchasing. These results indicate that 5% EMLA cream used as a local anesthetic in hemodialysis significantly reduces cannulation pain and lacks side effects, thus serving as a suitable method for the alleviation of cannulation pain and inconvenience in hemodialysis and the relief of psychological stress of nurses.

PURPOSE: To evaluate the usefulness and reproducibility of 1H MRS in different 1.5 T MR machines with different coils to compare the SNR, scan time and the spectral patterns in different brain regions in normal volunteers. MATERIALS AND METHODS: Localized 1H MR spectroscopy (1H MRS) was performed in a total of 10 normal volunteers (age; 20-45 years) with spectral parameters adjusted by the autoprescan routine (PROBE package). In all volunteers, MRS was performed in a three times using conventional MRS (Signa Horizon) with 1 channel coil and upgraded MRS (Echospeed plus with EXCITE) with both 1 channel and 8 channel coil. Using these three different machines and coils, SNRs of the spectra in both phantom and volunteers and (pre)scan time of MRS were compared. Two regions of the human brain (basal ganglia and deep white matter) were examined and relative metabolite ratios (NAA/Cr, Cho/Cr, and mI/Cr ratios) were measured in all volunteers. For all spectra, a STEAM localization sequence with three-pulse CHESS H2O suppression was used, with the following acquisition parameters: TR=3.0/2.0 sec, TE=30 msec, TM=13.7 msec, SW=2500 Hz, SI=2048 pts, AVG=64/128, and NEX=2/8 (Signa/Echospeed). RESULTS: The SNR was about over 30% higher in Echospeed machine and time for prescan and scan was almost same in different machines and coils. Reliable spectra were obtained on both MRS systems and there were no significant differences in spectral patterns and relative metabolite ratios in two brain regions (p>0.05). CONCLUSION: Both conventional and new MRI systems are highly reliable and reproducible for 1H MR spectroscopic examinations in human brains and there are no significant differences in applications for 1H MRS between two different MRI systems.

OBJECTIVES: A positive association between serum albumin levels and metabolic syndrome has been reported in observation studies, but it has not been established in the Korean population. The purpose of this study was to evaluate the association between serum albumin levels and the presence of metabolic syndrome among a sample of apparently healthy Korean adults. METHODS: This cross-sectional study analyzed data of 3189 community-dwelling people (1189 men and 2000 women) who were aged 40 to 87 years and were living in a rural area in Korea. Serum albumin levels were classified into quartile groups for each sex. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III guidelines with an adjusted waist circumference cut-off value (> or =90 cm for men and > or =85 cm for women). An independent association between serum albumin levels and metabolic syndrome was assessed by multiple logistic regression analysis. RESULTS: Higher serum albumin levels were associated with increased prevalence of metabolic syndrome. The odds ratio (95% confidence interval) of the prevalence of metabolic syndrome for the highest versus the lowest serum albumin quartiles was 2.81 (1.91 to 4.14) in men and 1.96 (1.52 to 2.52) in women, after adjusting for age, smoking status, alcohol consumption, and physical activity. When each metabolic abnormality was analyzed separately, higher serum albumin levels were significantly associated with hypertriglyceridemia and hyperglycemia in both sexes, and with abdominal obesity in men. CONCLUSIONS: These results suggest that higher serum albumin levels are positively associated with an increased risk of metabolic syndrome in Korean adults.
