PURPOSE: Our objective was to identify a coronary ligament of the knee joint on MR images. MATERIALS AND METHODS: We retrospectively evaluated 50 MR knee studies. Using MR imaging, the thickness and length of the anteroinferior portion of the capsule were measured and compared at the medial and lateral compartments. We also carefully dissected 5 fixed cadaveric knees and took photographs. RESULTS: The thickened synovial membrane(coronary ligament) of the anterior horn of the lateral meniscus appeared as a band of low signal intensity on MR images. On anatomic dissection of the knee joints, the inferior synovial attachment of the lateral meniscus was more redundant than the medial side. CONCLUSION: Anatomic correlation revealed that the coronary ligament contributed to the band-like structure at the anteroinferior aspect of the lateral meniscus.

PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

The purpose of the study was to develop and test the model for the quality of life in mothers of children with nephrotic syndrome. A hypothetical model was constructed on the basis of previous studies and a review of literature. The conceptual framework was built around ten constructs. Exogenous variables included in this model were mother's health, father's health, marital intimacy, mother's attitude on children, economic state, side effect of steroid, severity of illness and social support. Endogenous variables were mother's burden and quality of life. Empirical data for testing the hypothetical model were collected by using a self-report questionnaire from 152 mothers of children with nephrotic syndrom at the outpatient clinics and in the hospital. The data was collected from May, 1999 to August, 1999. Reliability of the seven instruments was tested with Cronbach's alpha which ranged from 0.71 - 0.92. For the data analysis, SPSS 8.0 WIN program and LISREL 8.20 WIN program were used for descriptive statistics and covariance structural analysis. The results of covariance structural analysis were as follow : 1.The hypothetical model showed a good fit with the empirical data.[x2 = .56, df = 3, p = .90(p > .05 ), GFI = .99, AGFI = .99, RMSR = .005.] 2. For the parsimony of model, a modified model was constructed by deleting 1 variable and excluding 2 paths according to the criteria of statistical significance and meaning. 3.The modified model also showed a good fit with the data[x2 = 2.83, df = 7, p = .90( p > .05 ), GFI = 1.00, AGFI = .97, RMSR = .011]. The result of the testing of the hypothesis were as follows : 1.Mother's health( gamma 21 = .26, t = 4.16), father's health( gamma 22 = .19, t = 2.92), marital intimacy( gamma 23 = .26, t = 4.13) and social support( gamma 28 = .12, t = 2.03) had a significant direct effect on the quality of life. 2. Mother's burden( beta 21 = -.20, t = -3.10) had a significant negative direct effect on the quality of life. 3. Mother's attitude on children( gamma 14 = -.34, t = .-4.57), mother's health( gamma 11 = -.22, t = -2.96) and side effect of steroid ( gamma 16 = -.23, t = .-2.69) had a significant direct negative effect on the burden. The result of this study showed that mother's health, marital intimacy, mother's burden, father's health, and social support had a significant direct effect on the quality of life. Mother's attitude on children, mother's health, and side effect of steroid had a significant direct effect on mother's burden. These six variables, mother's health, marital intimacy, father's health, social support, mother's attitude on children and side effect of steroid were identified as relatively important variables. The results of this study suggest, it needed to determine the nursing intervention will alleviate mother's burden and promote a greater quality of life in mothers of children with nephrotic syndrom.

Total knee arthroplasty(TKA) has been used for the treatment of knee joint pain, deformity, and instability caused by osteoarthritis, rheumatoid arthritis, or tuberculous arthritis, and by virtue of good results and rapid development, the procedure has been increasingly employed. With the development of total knee prosthesis, complications have also increased, however, and due to complications occurring up to six years after surgery, fusion occurs in about 2% of all replaced knees. The most common complication of TKA is loosening, followed by infection. Others are thrombosis, subluxation, dislocation and fracture, and complications may be divided into four groups: biologic, technical, specific to type of components, and associated with certain diagnosis. Where these complications occur, a patient must undergo a second procedure, but the success rate is lower than for the initial procedure. Exact etiological evaluation important clinically and radiologically. We illustrate the etiologies and radiologic characteristics of TKA complications according to classification.

PURPOSE: To report four cases in which temporary complication developed after using Gentian Violet as a marker in LASIK procedure. METHODS: Four cases who had undergone LASIK using Gentian Violet (Viscot Surgical Marker, U.S.A.) as a marker were followed. During follow up, corneal edema and opacity developed in landmark area which appeared as a hot spot in topography. Topical Corticosteroids and antibiotics applied for 3 weeks. RESULTS: At 3 month after LASIK, the corneal opacity and edema were disappeared. CONCLUSIONS: Temporary complication may develop by gentian violet following LASIK procedure. When using highly concentrated gentian violet marking pen, great attention should be paid not to make any corneal erosion.

PURPOSE: In order to know the effects of inaccurate laser shot of vertical or horizontal direction, we evaluated the clinical results of LASIK according to the use of fixation ring and the accuracy of the focusing beam on the corneal stromal bed. METHODS: LASIK was performed in 73 eyes with one surgeon between April, 2001 and January, 2002 were divided into two groups: those who exceeded -6.00D were high myopia group (37 eyes), and those who did not were low myopia group (36 eyes). We retrospectively analyzed the results of the LASIK in two methods, the one is the evaluation of the vertical directional error with the accuracy of the focusing beam and the other is the horizontal error with the use of fixation ring. We measured the preoperative and postoperative uncorrected visual acuity, spherical equivalent, and the postoperative predictability. RESULTS: There was no significant statistical difference in the spherical equivalent, uncorrected visual acuity, postoperative predictability between the use and nonuse of fixation ring and good and bad accuracy of focusing beam in high myopia and low myopia (P>0.05). CONCLUSIONS: These results suggest that a little difference in the accuracy of focusing beam on the corneal stromal bed and the use of fixation ring would not affect the clinical result after LASIK.

PURPOSE: To determine the usefulness of the fat-suppressed (FS) conventional spin-echo (CSE) sequence for the diagnosis of meniscal tears. MATERIALS AND METHODS: We retrospectively reviewed 323 MR images of the knee, the standard of reference being the findings of arthroscopy. In all knees, fast SE proton density-weighted and T2-weighted sagittal and coronal images and double-echo in steady state (DESS) sagittal images were obtained, and during 202 MR Procedures, FS-CSE T1-weighted sagittal images were also obtained. The results of MR imaging were then correlated with those of arthroscopy, the accuracy with which meniscal tears were diagnosed being compared between two groups: group I (202 knees for which FS-CSE T1-weighted sagittal images were obtained), and group II (121 knees for which these images were not obtained). For statistical analysis the chi-square test was used. RESULTS: In group 1, sensitivity, specificity and accuracy were 94.7%, 92.4% and 93.5%, respectively, for the medial meniscus, and 83.3%, 95.7% and 90.5% for the lateral meniscus. In group II, the corresponding findings were 92.5%, 94% and 93.3%; and 87.3%, 98.2% and 92.5%. The differences between the groups were not statistically significant (p>0.05) CONCLUSION: For meniscal tears of the knee, the addition of FS-CSE T1-weighted MR imaging to the fast SE proton density-weighted, T2-weighted and DESS sequences does not enhance diagnostic accuracy.
