PURPOSE: This exploratory study aims to identify various factors influencing the rehabilitation nursing competencies (RNC) of nurses in various types of health institutes. METHODS: The researcher developed a questionnaire consisting of 45 items based on the ARN rehabilitation nursing competency model. Subjects were 434 nurses working at general hospitals, long-term care facilities, or community health centers. RESULTS: Nurses' RNC were significantly higher among those who have higher levels of education, receive continuing education in rehabilitation nursing, and practice more frequently in rehabilitation nursing. Age and duration of nursing career were significant only for interprofessional care domain. General hospital nurses scored highest in every domain while nurses working at long-term care facilities scored lowest in every domain. Multiple regression analysis showed that practicing daily or more than twice per week in rehabilitation nursing, achieving master's degree or higher, and working at long-term care facilities were statistically significant factors with RNC. These factors explained 31.1% of the total variability in RNC in this sample. CONCLUSION: Currently, there is no official certification program for rehabilitation nurse practitioners in South Korea. The results of this study would be useful in developing RNC training programs for Korean nurses, and provide strong evidence for necessity of certified rehabilitation nurse specialists.

BACKGROUND: Pneumonia is a common medical complication after acute stroke, and makes a considerable influence on the prognosis. It is potentially preventable or treatable if early recognized. Thus, the identification of which patients are at risk for the development of pneumonia is clinically significant. METHODS: A total of 240 patients with an acute stroke who were consecutively admitted to a Seoul National University Hospital were studied. The following prognostic factors were accounted for in the statistical analyses: age, sex, hypertension, diabetes, cardiac disease, smoking, recurrent stroke, NIHSS, modified Rankin scale (mRS), the presence of dysphagia, blood pressure, body temperature, white blood cell count, blood sugar, fibrinogen, Levin tube insertion, Foley catheter insertion, and subtype of stroke. RESULTS: Pneumonia was diagnosed in 36 (17.0%) patients during the acute stage of stroke, particularly within 2 weeks. Average admission stay of patients with pneumonia was 38.7 days, whereas it was 19.3 days for those without pneumonia. By multivariate analysis, Levin tube insertion, body temperature, recurrent stroke, and mRS were significant predictor of pneumonia development. Forty percent of patients with four or five points of mRS developed pneumonia, compared to 6% in less than four points. CONCLUSIONS: Our results show that the patients who have Levin tube, high mRS, or recurrent stroke tend to develop pneumonia after acute stroke. It is important for early detection and prevention of pneumonia in patients with high mRS.

Collapsing glomerulopathy (CG) has become an important cause of end-stage renal disease (ESRD). First delineated from other proteinuric glomerular lesions in the 1980s, CG is now recognized as a common, distinct pattern of proliferative parenchymal injury that portends a rapid loss of renal function and poor responses to empirical therapy. The first cases in the literature trace back to human-immunodeficiency-virus (HIV)-negative patients who underwent biopsy in 1979. A 45-year-old male patient complained of hematuria and proteinuria eight years ago. He showed an abrupt serum creatinine increase from 1.75 to 2.65mg/dL in the last preceding months. Afterwards, his serum creatinine progressively increased up to 6.82mg/dL. Moreover, his 24 h urine protein level was determined to have reached 6,171 mg/day, as opposed to 670 mg/day a year earlier. Consequently, renal biopsy was performed, and its result showed collapsing glomerulopathy, compatible with the diagnosis. He has undergone continuous ambulatory peritoneal dialysis as renal replacement therapy. Thus, it is reported herein that a patient clinically diagnosed with chronic kidney disease eight years ago showed a sudden renal-function decrease and was clinicopathologically diagnosed with collapsing glomerulopathy based on the results of his renal biopsy.

OBJECTIVE: To determine the ability of MR imaging to detect the pathological changes occurring in radiofrequency (RF) thermal lesions and to assess its accuracy in revealing the extent of tissue necrosis. MATERIALS AND METHODS: Using an RF electrode, thermal lesions were created in the livers of 18 rabbits. The procedure involved three phases. In the acute phase, six animals were killed the day after performing thermal ablation with RF energy, and two on day 3. In the subacute and chronic phases, eight rabbits underwent percutaneous hepatic RF ablation. After performing MR imaging, two animals were sacrificed at 1, 2, 4, and 7 weeks after the procedure, and MR-pathologic correlation was performed. RESULTS: In the acute phase, the thermal ablation lesions appeared at gross examination as well-circumscribed, necrotic areas, representing early change in the coagulative necrosis seen at microscopic examination. They were hypointense on T2-weighted images, and hyperintense on T1-weighted images. Gadolinium-enhanced MR imaging showed that a thin hyperemic rim surrounded the central coagulative necrosis. In the subacute phase, ablated lesions also showed extensive coagulative necrosis and marked inflammation at microscopic examination. Beyond two weeks, the lesions showed gradual resorption of the necrotic area, with a peripheral fibrovascular rim. The size of lesions measured by MR imaging correlated well with the findings at gross pathologic examination. CONCLUSION: MR imaging effectively demonstrates the histopathological tissue change occurring after thermal ablation, and accurately determines the extent of the target area.
