PURPOSE: To evaluate the incidence of disc extrusion and neurologic deficit, the relation between disc extrusion and neurologic deficit and the treatment results according to our basic treatment principles in lower cervical facet joint fracture and dislocations MATERIALS AND METHODS: Twelve patients were evaluated, 8 male and 4 female with an average age of 41 years comprised the group. Six injuries were attributable to automobile accidents, 5 to fall from building, bed, floor and hill, and one to stand on her head. One case was distractive-flexion stage (DFS) 1, 9 cases with DFS 2 and 2 cases with DFS 3. Plain X-ray, CT, Myelo CT and MRI were used as a diagnostic tools. As a treatment criteria, feasibility of closed reduction, status of neuroglogic injury, and stability of injured spine were considered. Anterior cervical discectomy and fusion in accompanied disc extrusion, posterior reduction and fusion with triple wiring in unreduced dislocation, and anterior decompression and fusion in incomplete cord and root injury were selected as a basic treatment principles. RESULTS: Ten out of 12 cases (83%) showed neurologic deficits, 2 complete cord injury, 1 incomplete cord injury, and 7 radiculopathy. Nine out of 12 (75%) demonstrated disc extrusion and all disc extruded patients had neurologic deficits. Anterior cervical discectomy and fusion (ACDF) were performed in 5 cases, ACDF and posterior reduction with triple wiring (PRTW) in 4 cases, PRTW in 1 case, and skull traction and philadelphia brace in 2 cases. Seven radiculpathy patients were completely recovered and one incomplete cord injury patient can ambulate with spastic gait after surgery. There were 2 bed sore and 1 pneumonia in complications. CONCLUSION: Soft disc extrusion should be evaluated carefully with MRI and CT in lower cervical spine injury with the facet joint fracture-dislocations before the decision of treatment. As disc extrusion always accompanies neurologic deficit, it must be surgically treated by anterior cervical discectomy and fusion.

Venous thrombosis is uncommon in young individuals. Hypereosinophilia is a rare cause of thrombosis that usually involves the heart and small vessels like retinal vessels. We report a case of massive deep vein thrombosis that developed in a young patient with hypereosinophilia who was successfully treated with continuous local infusion of urokinase.

Journal of Korean Academy of Nursing 2005;35(8):1493-1499
BACKGROUND: Adequate staffing is necessary to meet patient care needs and provide safe, quality nursing care. In November 1999, the Korean government implemented a new staffing policy that differentiates nursing fees for inpatients based on nurse-to-bed ratios. The purpose was to prevent hospitals from delegating nursing care to family members of patients or paid caregivers, and ultimately deteriorating the quality of nursing care services. PURPOSE: To examine nurse staffing levels and related factors including hospital, nursing and medical staff, and financial characteristics. METHODS: A cross-sectional design was employed using two administrative databases, Medical Care Institution Database and Medical Claims Data for May 1-31, 2002. Nurse staffing was graded from 1 to 6, based on grading criteria of nurse-to-bed ratios provided by the policy. The study sample consisted of 42 tertiary and 186 general acute care hospitals. RESULTS: None of tertiary or general hospitals gained the highest nurse staffing of Grade 1 (i.e., less than 2 beds per nurse in tertiary hospitals; less than 2.5 beds per nurse in general hospitals). Two thirds of the general hospitals had the lowest staffing of Grade 6 (i.e., 4 or more beds per nurse in tertiary hospitals; 4.5 or more beds per nurse in general hospitals). Tertiary hospitals were better staffed than general hospitals, and private hospitals had higher staffing levels compared to public hospitals. Large-sized general hospitals located in metropolitan areas had higher staffing than other general hospitals. Occupancy rate was positively related to nurse staffing. A negative relationship between nursing assistant and nurse staffing was found in general hospitals. A greater number of physician specialists were associated with better nurse staffing. CONCLUSIONS: The staffing policy needs to be evaluated and modified to make it more effective in leading hospitals to increase nurse staffing.

We report a case of ciliated hepatic foregut cyst which was incidentally found in a 64 year-old man. The cyst, 6 cm in diameter, was unilocular, solitary and was located in the medial segment of left lobe, just below the Glisson's capsule. Microscopically, the cyst wall consisted of 4 layers; pseudostratified ciliated columnar epithelium, subepithelial loose connective tissue, smooth muscle bundles and an outermost fibrous capsule. Although cartilage or subepithelial sero-mucous glands were absent, the morphologic features of the cyst correspond with those of an incomplete form of brochogenic cyst.

PURPOSE: It is well established that the presence of axillary nodal metastases is the most important prognostic factor in primary operable breast cancer. However, it has also been shown that 15-30% of patients without lymph node metastases as assessed by light microscopy have recurrence within 10 years. In this study, our aim was first to investigate the diagnostic value of immunohistochemical staining in detecting micrometastases and secondly to correlate their presence with prognosis (recurrence and survival) MATERIALS AND METHODS: We retrospectively analyzed 492 axillary nodes from 49 consecutive node-negative invasive breast cancers treated at Kyung-Hee University Hospital from 1991 to 1995 with average follow-up of 60.2 (21-100) months. An additional section of original paraffin blocks was cut and stained by immunohistochemical chemical technique using monoclonal antibodies (AE 1/3 and No.7) to cytokeratin. RESULTS: Micrometastases with individual cell and cell clusters were readily detected by this technique in 27% of the cases. These were no predictors of micrometastses among the clinicopathological data of patient. The presence of micometastases wes not associated with disease-free and overall survival but loco-regional recurrence rate. CONCLUSIONS: A combination of immunohistochemistry and serial sectioning of axillary lymph node would help evaluate the significance of occult axillary metastases. Patients with node-negative disease may relapse after many years and prolonged follow-up is required to establish the role of mirometastases. Such an approach, together with a search for bone marrow micrometastases and epidemiologic, clinical, pathologic and/or biochemical prognostic factors, may serve to identify high risk patients in the presumed node-negative group. It would provide a rational basis for the selective use of adjuvant therapy.

Solitary fibrous tumors (SFTs) most often involve the pleura and also may encompass the peritoneum and nonserosal sites. They occur as solitary encapsulated tumors and pursue a relatively benign clinical course. The usual criteria for malignancy are high cellularity, mitotic activity (more than 4 per 10 high-power fields), cellular pleomorphism, hemorrhage and necrosis as well as infiltrative growth. We report a case of malignant SFT of pleura who presented with an anterior mediastinal mass. Grossly, it was a 10x8x6.5 cm sized, encapsulated and well-demarcated, solid neoplasm with areas of extensive necrosis. Microscopically, parallel or haphazard arrangement of spindle cells with variable degrees of collagenous background were noted. Storiform fascicle formation, hemangiopericytoma-like pattern, and epithelioid cell clusters were often intermingled. Nodular areas with high cellularity and mitotic activity (> or =10/10 HPFs) were scattered throughout the neoplasm, however no definite cellular pleomorphism was encountered. Tumor cells were immunoreactive for vimentin and CD-34, which distinguished them from the mesothelial cells. Electron microscopically, they revealed fibroblastic and myofibroblastic differentiation.

PURPOSE: The purpose of this study was to investigate the influencing factors on externalized and internalized problem behaviors among high school students. METHODS: The subjects for this study were 707 students in two high schools in K province. The data were collected during the period from October to November, 2014 by use of questionnaires. The instruments used were the Korean Youth Self-report, Daily Hassles Questionnaire, State-Trait Anger Expression Inventory, and Ego Resiliency Scale. The data were analyzed using SPSS. RESULTS: Significant predictors to explain externalized problem behaviors comprised anger-out, anger-in, anger-control, relation with parents, daily stress, and religion. It was found that these factors explained 46% of externalized problem behavior. Ego resiliency, anger-in, daily stress, gender, relation with parent, and anger-out were significant predictors to explain internalized problem behaviors. It was found that these factors explained 45% of internalized problem behaviors. CONCLUSION: This study suggests that the influencing factors on problem behaviors differ from externalized and internalized problem behaviors. So these findings will provide the basic data to develop a program that is differentiated by problem behavior type.
