PURPOSE: The purpose of this study was to identify nurses' image and its related factors to make nurses' image among academic and vocational high school teachers in Korea. METHOD: Study samples were composed of 470 teachers who were from 12 high schools in G and J city located in southwestern part of Korea. Data were collected from August 26 to October 4, 2002. The internal consistency of the total scale was Cronbach's = .940. RESULT: In order to make nurses' image, 76.4% of respondents were influenced by the experience of their hospitalization in visiting hospitals. The mean score of nurses' image in general was 3.19 0.55; in four subcategories, 3.46 0.60 for professional image, 3.28 0.69 for traditional image, 2.93 0.70 for social image, and 2.91 0.64 for vision of nursing career. The mean score of nurses' image in general was more positive significantly in the 50's age group (F=6.43, p= .002) and in male groups (t=2.92, p= .002). CONCLUSION: On the basis of these findings, nursing professionals need to improve their working conditions, aspiration in job, and autonomy of nurses in their practice fields, monitor the mass media and other publishing materials continuously, and share the appropriate information on nursing profession to the school teachers and the public.

Dissecting aortic aneurysm is relatively rare in those under 40 years of age without high risk factors. After dissecting aortic aneurysm is occurred, the coronary artery is rarely perfused by false lumen. We present a thirty two-year-old man who showed Debakey type 1 dissecting aortic aneurysm with right coronary artery perfused by false lumen of ascending aorta and with congestive heart failure due to aortic insufficiency without discernible risk factor. Medical and surgical treatment (Modified Bentall's operation) were successfully performed. The pathologic report showed combined cystic medial necrosis. Now he is well tolerated and stable only with anticoagulation during follow up 18 months.

Peripheral primitive neuroectodermal tumor (pPNET), a rare, highly aggressive neoplasm of indetermined histogenesis, occurs typically in the soft tissues of the chest wall and the paraspinal region. Comprehensive diagnostic studies including histological, ultrastructural, immunohistochemical and molecular analyses have been stressed to diagnose this entity. We report a case of primary renal PNET which was incidentally found in a 59-year-old man who presented with generalized weakness for 4 months. He was diagnosed as a non-insulin dependent diabetes mellitus 15 years ago and has been made well by oral therapy. An ill-defined mass, measuring 3.5 3 cm, located in the left kidney and perirenal fat, was incidentally found by ultrasonogram during a renal diabetic examination. The mass was resected because of the unresponsiveness against one-year chemotherapy and radiation therapy. Grossly, a homogeneously solid, gray-white mass, measuring 2.8 1.8 cm, was noted in the mid portion of renal cortex. The mass showed severe adhesion to the perirenal fatty tissue. Microscopically, tumor cells were rather uniform, small round with scanty cytoplasm and often showed rosette formation. Ultrastructurally, they showed membrane-bound dense core granules, measuring 125~150 nm, intercellular junctions and microvillous cytoplasmic projections. The tumor cells were uniformly immunoreactive for neuron-specific enolase and were focally immunoreactive for CD99 (013), chromogranin, synaptophysin and cytokeratin. They were not reactive for S-100 protein, vimentin, Leu-7, leukocyte common antigen, desmin and smooth muscle actin. To our knowledge, this is the smallest renal PNET in literature.

Immunoglobulin G4 (IgG4)-related kidney disease is a chronic immune-mediated fibro-inflammatory disorder characterized by multiple organ infiltration with IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis or tumefactive lesions. Previous studies have explored IgG4-related kidney disease, increasing our understanding of its clinical manifestations, and pathological and radiologic findings. However, IgG4-related kidney disease can be misdiagnosed since it mimics malignancies. We report a case of a 77-year-old Korean man diagnosed with IgG4-related kidney disease with membranous proliferative glomerulonephritis, presenting with a renal pelvic mass suspected of being malignant.

Nonautoimmune hyperthyroidism is a very rare cause of congenital hyperthyroidism that is usually caused by an activating mutation in the thyroid-stimulating hormone receptor (TSHR) gene. In this report, we describe a case of nonautoimmune hyperthyroidism in a patient with TSHR mutation. Our patient was the younger of a set of twins born at 36 weeks and 6 days of gestation. The patient was noted to be more irritable than the older twin at 80 days of age, and the mother was taking methimazole for Graves’ disease that had been diagnosed 12 years prior. Therefore, a thyroid function test was conducted for the patient. The results revealed subclinical hyperthyroidism, and tests of antithyroglobulin antibody, antithyroid peroxidase antibody, and anti-thyroid-stimulating hormone (TSH) receptor antibody were all negative. During follow-up, at around 4 months of age, free T4 increased to 2.89 ng/dL, and TSH was still low at 0.01 μIU/mL; therefore, 3 mg/day of methimazole was initiated. Whole-exome sequencing showed a heterozygous variant of c.1800C>T (p.Ala627Val) in the TSHR gene. Testing in the family confirmed an identical variant in the patient's mother, leading to diagnosis of familial nonautoimmune hyperthyroidism inherited in an autosomal dominant pattern. This is the second report of A627V confirmed as a germline variant.

Macroglobulinemia is the result of an uncontrolled proliferation of lymphocytes and plasma cells in which a large IgM M protein is produced. IgM monoclonal gammopathy is recognized in a variety of lymphoproliferative diseases and Waldenstr?m's macroglobulinemia (WM) is the most frequent disease in this group. We report a case of nodal marginal zone B-cell lymphoma (Nodal MZBCL) accompanied by monoclonal macroglobulinemia. A 58-year-old man was admitted to the hospital with chronic fatigue and dyspnea. Physical examination revealed cervical, subaxillary, and inguinal lymphadenopathy. Histopathologically, monocytoid B cells with abundant pale cytoplasm and small nuclei infiltrated the cervical lymph node. The neoplastic cells were positive for CD 20, bcl-2, and IgM. The serum and urine electrophoresis showed monoclonal spike in the globulin region and immunoelectrophoresis demonstrated immunoglobulin of IgM, kappa type. Immunohistochemically, this monoclonal gammaglobulinemia (IgM, Kappa) was produced and secreted from the nodal MZBCL. This is the first report of nodal MZBCL accompanying macroglobulinemia in Korea.

BACKGROUND: It is stated frequently that patients with spinal block may be drowsy, although they may not have received any sedative drugs. Intrathecal clonidine increase the duration of sensory and motor blockades, and also has a sedative effect. Thus we conducted this study to investigate the effects of spinal anesthesia and intrathecal clonidine on propofol hypnotic requirements. METHODS: Forty-five adult patients scheduled to undergo local or spinal anesthesia were enrolled in this study. Group 1 included patients on local anesthesia, group 2 were patients on spinal anesthesia with 0.5% hyperbaric bupivacaine, and group 3 were patients on spinal anesthesia with 0.5% hyperbaric bupivacaine and 75microgram clonidine. The target controlled infusion (TCI) of propofol was started at a target concentration of 1microgram/ml. We checked the lowest BIS during 5 min observation after the effect site concentration (Ce) had been reached (1microgram/ml). The TCI of propofol was then restarted at a target concentration of 1.5microgram/ml and we checked the lowest BIS during 5 min observation after the Ce had been reached (1.5microgram/ml). We also checked the Ce when the BIS reached 80 and 70. RESULTS: The minimum BIS's at 1 microgram/ml Ceiiwere 86.9 +/- 11.3 (Group 1), 80.5 +/- 8.5 (Group 2) and 66.9 +/- 15.5 (Group 3), and the minimum BIS's at 1.5microgram/ml Ce were 76.0 +/- 13.4, 62.9 +/- 12.4, 48.5 +/- 13.7, respectively. The Ce's of propofol at BIS 80 were checked initially at 1.4 +/- 0.5microgram/ml (Group 1), 1.1 +/- 0.3microgram/ml (Group 2) and 0.8 +/- 0.3microgram/ml (Group 3). The Ce's of propofol at BIS 70 were 1.8 +/- 0.6microgram/ml, 1.4 +/- 0.3microgram/ml and 1.0 +/- 0.3microgram/ml, respectively. The Ce's of Group 2 and Group 3 at BIS 80 and BIS 70 were statistically lower than those of Group 1 (P < 0.05), and the Ce's of Group 3 at BIS 80 and BIS 70 were statistically lower than those of Group 2 (P < 0.05). CONCLUSIONS: Spinal anesthesia and intrathecal clonidine reduce the requirement of propofol for conscious sedation. The Ce of propofol for conscious sedation is 1.4-1.8microgram/ml for local anesthesia, 1.1-1.4microgram/ml for spinal anesthesia with 0.5% hyperbaric bupivacaine, and 0.6-1.0microgram/ml for spinal anesthesia with 0.5% hyperbaric bupivacaine and 75microgram clonidine.

BACKGROUND: To evaluate the efficacy and safety of paclitaxel and cisplatin against advanced non-small cell lung cancer (NSCLC) as a second-line chemotherapy. SUBJECTS AND METHODS: Twenty-five patients were enrolled. The patients received 200 mg/m2 paclitaxel as a 3-hour intravenous infusion and 60 mg/m2 cisplatin as 30-minute intravenous infusion with vigorous hydration on day 1 every 28 days. The response was assessed every 2 cycles. RESULTS: All 25 patients were assessed for their response and toxicity. Partial responses were observed in 5 patients. The overall response rate was 20% (95% confidence interval, 4%~36%) and the median response duration was 4.5 (range, 2-11) months. The median time to progression was 3.3 (range, 0-14) months. The median overall survival of all patients was 7.4 (range, 1.3-39) months. The hematologic toxicities were minor and easily controlled. CONCLUSION: The combination chemotherapy of paclitaxel and cisplatin as a second-line treatment has a moderate efficacy with an acceptable toxicity in patients with advanced NSCLC.

BACKGROUND: Epigenetic alterations in certain genes are now known as at least important as genetic mutation in pathogenesis of cancer. Especially abnormal hypermethylation in or near promoter region of tumor suppressor genes (TSGs) are known to result in gene silencing and loss of gene function eventually. The authors tried to search for new lung cancer-specific TSGs which have CpG islands and HpaII sites, and are thought to be involved in carcinogenesis by epigenetic mechanism. METHODS: Tumor tissue and corresponding adjacent normal tissue were obtained from 10 patients who diagnosed with non small cell lung cancer (NSCLC) and underwent surgery in Konyang university hospital in 2005. Methylation profiles of promoter region of 21 genes in tumor tissue & non-tumor tissue were examined with HpaII-MspI methylation microarray (Methyl-Scan DNA chip(R), Genomic tree, Inc, South Korea). The rates of hypermethylation were compared in tumor and non-tumor group, and as a normal control, we obtained lung tissue from two young patients with pneumothorax during bullectomies, methylation profiles were examined in the same way. RESULTS: Among the 21 genes, 10 genes were commonly methylated in tumor, non-tumor, and control group. The 6 genes of APC, AR, RAR-b, HTR1B, EPHA3, and CFTR, among the rest of 11 genes were not methylated in control, and more frequently hypermethylated in tumor tissue than non-tumor tissue. CONCLUSION: In the present study, HTR1B, EPHA3, and CFTR are suggested as possible novel TSGs of NSCLC by epigenetic mechanism.
