PURPOSE: To evaluate the anatomic and functional change in acutely obstructed kidneys, and the probability of functional recovery after resolving the obstruciton. MATERIALS AND METHODS: There were 5 animal groups(6 rabbits in each group)-normal control group, 4 acute ureteral obstruction group. Each of the latter group was imaged with Gd-DTPA enhanced dynamic MR 2, 6, 24, and 48 hours after ligation of the left proximal urter, respectively. We compared the findings of dynamic MR imaging and histopathological findings. RESULTS: We could observe centripetal movement of dark band pattern which could be defined as 3 phasesrenal cortex, outer medulla, and inner medulla in normal rabbits. The appearance of the dark band pattern was delayed or absent in ureteral obstruction group with a linear relationship to the duration of the obstruction. CONCLUSION: Gd-DTPA enhanced MR can be used to differentiate acute obstructive nephropathy from other causes of nephropathy and foretell the prognosis of the obstruction.

PURPOSE: To compare the incidence between author's first and current report on urinary tract stone in patient with spinal cord injury and to evaluate the effectiveness of recent developed in medical technology and care on in treating the patients. MATERIALS AND METHODS: We reviewed urinary tract stone in 257 patients with paraplegia or quadriplegia after spinal cord injury. These patients were diagnosed retrospectively by KUB and intravenous urography at the Korea Veterans Hospital during 10years from January, 1984 to December, 1993. We evaluated and compared the overall incidence, incidence of specific location of urinary tract, recurrent rate, incidence according to the level of spinal cord injury, and the duration of development in urinary tract stone. RESULTS: Total patients were 257 with 186(72.4%) paraplegia and 71(27.6%)quadriplegia. Overall incidence of the stone was 16.0% in this study and 38.1% in the first study. Incidence of the stone in individual organ ;5.5% in kidney, 1.2% in ureter, and 13.6% in urinary bladder. The recurrent rate was 29.3% in this study and 40.6% in the first study. Incidence of the stone according to the level of spinal cord injury was as follows;15.6% in cervix, 17.1% in upper thorax, 17.9% in lower thorax and 13.9% in lumbar. The stone developed during the first 4 years and between 12 to 16 years following spinal cord injury was 28.3% each. CONCLUSION: Overall incidence and recurrent rate of urinary tract stone was obviously decreased since the first study. Highest incidence of the stone occurred in urinary bladder and in patient with lower thoracic spinal cord injury, which is similar to first report. Peak incidence of the stone was in the first 4years, and another peak was in 12-16years after spinal cord injury. The decreased overall incidence of urinary tract stone maybe attributable to the development in medical technology and care, and active rehabilitation.

PURPOSE: This study aims to identify the relationship between person-centered critical care nursing (PCCN) and family satisfaction for intensive care unit (ICU) nurses.METHODS: This research used a cross-sectional survey. The participants were 142 nurses and 121 family members from 8 ICUs in 4 hospitals in B city. The questionnaire survey was conducted between December 2018 and March 2019. The eight ICUs were divided into those that scored high and those that scored low for person-centered care relative to the average score for PCCN, and the difference in family satisfaction between the ICUs with high and low scores was compared using t-test.RESULTS: The mean score of PCCN was 3.68±0.40 out of 5. In the subcategories of PCCN, “comfort”was the highest at 3.95±0.49, followed by “respect” at 3.73±0.57, “compassion” at 3.59±0.57, and “individuality” at 3.47±0.54. The average score of family satisfaction with the ICUs was 3.45±0.67 out of 5. In its subcategories, “emotion” was the highest at 3.69±0.72, followed by “information” at 3.61±0.75, “participation” at 3.30±0.79, and ”resources‘ at 3.20±0.80. The family satisfaction (3.75±0.54) with the ICU of the highest-scoring PCCN was significantly higher than the family satisfaction (3.25±0.53) with the ICU with the lowest-scoring PCCN (t=4.97, p<.001).CONCLUSION: The results suggest that the PCCN scores of ICU nurses should be promoted to improve family satisfaction. It is necessary to pursue a variety of ways to secure the provision of person-centered nursing practice in ICUs.

Polyarteritis nodosa is systemic necrotizing vasculitis of medium and small-sized arteries and results in variable manifestations due to ischemia of the involving organs. Diagnosis can either be made pathologically by demonstrating necrotizing vasculitis of arteries or angiographycally by demonstrating small arterial aneurysm. We experienced a case of PAN with dilated cardiomyopathy, confirmed by clinical feature, renal biopsy, angiography and echocardiography.

Lymphoepithelioma-like carcinoma (LELC) is an undifferentiated carcinoma with predominant lymphocytic infiltration, which is associated with Epstein-Barr virus (EBV) in variable proportions. We report two cases of carcinoma with predominant lymphoid stroma in hepatobiliary system. The first case was a lymphoepithelioma-like undifferentiated carcinoma with focal differentiation of cholangiocarcinoma (cytokeratin 19+) and hepatocellular carcinoma in light microscopy. The infiltration of CD8+ T lymphocytes was observed in the tumor and the surrounding hepatic parenchyme. In this tumor, EBV was detected and LMP1 was positive immunohistochemically. The second case showed the mixed features of lymphoepithelioma-like carcinoma and cholangiocarcinoma with predominant lymphoid stroma. In this case, EBV was detected. LELC of hepatobiliary system is an entity distinguished from conventional carcinoma with lymphoid stroma, and its association with EBV warrants further research.

PURPOSE: To evaluate the pattern of colonic diverticulosis according to age and sex, and recent trend. MATERIALS AND METHODS: The authors retrospectively reviewed 120 cases of colonic diverticulosis in 1,020 patients who had undergone a double contrast barium enema examination between January 1st, 1993, and December 31st, 1995, and analyzed the frequency, size, multiplicity and anatomical site, according to age and sex. Diverticulum size was classified into one of three groups : less than 5mm, 5-10mm, over 10mm in diameter. RESULTS: The overall incidence of colonic diverticulosis was 120 cases among 1,020 patients(11.8%) with an incidence 5.3 times higher in males than in females. Peak incidence was in the fifth decade, with 19 cases (15.8%) among males, and after the sixth decade, with four cases(3.3%) among females. Mean age was 57.7 years. Diverticulum size of 5-10mm in diameter was predominant 2% of cases) ; average diameter was 5-6mm. The incidence of colonic diverticulosis was 5.1 times more frequent in the right colon(101 cases) than in the left (20 cases). CONCLUSION: The overal overall incidence of colonic diverticulosis has continually increased; in addition it has also recently increased slightly in left-sided colon. This is thought to be due to various factors, both congenital and acquired, including longer life with good health care, constipation, irritable bowel syndrome, stress and the tendency of eating patterns to more closely resemble those of the west.

Indolent T-lymphoblastic proliferation has been rarely reported in the upper aerodigestive tract. The lymphoid cells associated with this condition have the morphological and phenotypical features of immature thymocytes. However, their pathogenesis and biology are unknown. We present an unusual type of tumor infiltrating lymphocytes in a case with hepatocellular carcinoma, presumed to be a T-lymphoblastic proliferation. A 58-yr-old female patient presented with indigestion and a palpable epigastric mass. The abdominal computed tomography revealed a mass in the S6 region of the liver. A hepatic segmentectomy was performed. Microscopic examination showed dense isolated nests of monomorphic lymphoid cells within the tumor. Immunohistochemically, the lymphoid cells were positive for CD3, terminal deoxymucleotide transferase (TdT) and CD1a. In addition, they showed dual expression of CD4 and CD8. The polymerase chain reaction used to examine the T-cell antigen receptor gamma gene rearrangement showed polyclonal T-cell proliferation. This is the second case of hepatocellular carcinoma combined with indolent T-lymphoblastic proliferation identified by an unusual tumor infiltrating lymphocytes.
