An accurate preoperative evaluation of lymph nodes(LNs) in gastric cancer is a prerequisite for successful surgery and favorable prognosis. We retrospectively analyzed the Ct accuracy in perigastric LN localization and LN staging of gastric cancer as well as the size criteria for the metastasized LN in 64 patients who hed undergone a surgery for gastric cancer. The results of perigastric LNs evaluation by CT are as follows; sensitivity 67%(64/95), specificity 90%(839/929), accuracy 88%(903/1024). Of 95 pathologically metastasized LN groups, 66 could be retrospectively identified on Ct scans(69%). In LN staging, CT was correct in 60%(38/64), overstaged in 32%(21/64), and understaged in 8%(5/64). The perigastric LN groups which were easily localized on CT were #3, 7, 8, and 13. The mean size of metastasized LNs on CT according to the I.N group was #3 (13mm), #4(9mm), #6 (10mm), #7(10.5mm), #8 (10mm), #9 (11mm), #13 (9mm).

PURPOSE: The purpose of this study was to identified the male nurses' encounter in adapting themselves in the hospital settings dominated by the female nurses in number. METHOD: Data were collected through the in-depth interview of 16 male nurses and analysed through the grounded theory methodology. RESULT: The behaviors of male nurses for job-adaptation can be summarized as a series of struggles to consolidate their own ground. They have made tremendous efforts to hold their own ground in the nursing profession composed of a large numbers of female nurses, while they have experienced many difficulties and problems as minorities. They have struggled to adapt themselves professionally through efforts such as; challenging the social and professional barriers, identifying the job identity, empowering themselves through self-development and dedication, expanding their influence among colleagues. In spite of these efforts, they had the perception that nursing is not a lifelong occupation for them. Thus, they had tendency to find outlets of change to occupations. CONCLUSION: A specific strategy is needed to provide an environment that is helpful for males in integrating into and adapting to the nursing profession.

Leiomyoma is the most common benign tumor of the esophagus, but it still occurs rarely as compared with the incidence of carcinoma in this area. Most of leiomyomas may manifest itself with unusual and inconsistent symptoms, and found incidentally during endoscopic or radiographic examination. Those who menifested symptoms are included as dysphagia and vague pain mostly. We experienced recently two cases with esophageal leiomyoma who underwent successful surgical resection and endoscopic enucleation, respectively.

OBJECTIVE: Eating disorders are a common clinical problem among young women in Asian countries. The aim of this study is to determine the medical effects of anorexia nervosa (AN) in the Korean population. METHODS: We comprehensively investigated medical complications including haemodynamic, haematologic, endocrine, and bone density abnormalities in 67 Korean women with AN, together with 194 healthy Korean women of comparable age with a cross-sectional design. RESULTS: In AN, 36.9% were anaemic, 50.8% were leukopenic, 35.5% were hypoproteinemic, 7.9% were hypokalemic, 9.5% had increased alanine aminotransferase, 6.3% were hyperbilirubinemia, 14.5% were hypercholesterolemia, 14.8% had decreased triiodothyronine. Osteopenia at any one site was identified in 43.3% and an additional 13.4% had osteoporosis. The lowest-ever body mass index was the main determinant of bone mineral density. CONCLUSION: Our data in Korean patients with AN show high frequencies of laboratory abnormalities for medical complications. This study emphasizes the importance of recognizing AN as a medical risk in young Korean women.

To assess the adverse effects of dust on pulmonary function and to determine the association between subjective respiratory symptoms, cognitions about working environments and pulmonary functions, the study was conducted on 719 coal mine workers (395 workers on direct part, 324 workers on indirect part) being employed in a coal mine industry located in Hwa-Soon area. Questionnaires on respiratory symptoms and cognitions about working environments were filled out by themselves, and pulmonary function test was given by trained doctors. The results obtained were as follows ; 1. Significantly increased subjective respiratory symptoms prevalence were found in the workers on direct part comparing to workers on indirect part, and symptoms prevalence rate was higher in sputum, coughing, respiratory difficulty, palpitation and chest pain in order. 2. Significantly increased cognitions degree about working environments were found in workers on direct part comparing to workers on indirect part, and the degree was higher in dust concentration, temperature, working density and humidity in order. 3. FVC, FEV(0.5), FEF(200-1200ml) and FEF(25-75%) were lower for workers on direct part than that for workers on indirect part. 4. In workers on direct and indirect part, lung functions except FEF(200-l200ml) for the high subjective symptom group was smaller than that for the low group. There was not significane statistically, but the significane was found in FVC and FEVt in total coal workers. 5. In workers on direct part, FEVt and FEF(25-75%) for high cognition group about working environmental conditions was smaller than that for the low group but other lung functions were reversed. But in workers on indirect part, similar results was found and the significance was found in FEV(0.5) FEF(25-75%) and FEF(200-1200ml) in total coal workers. 6. Lung functions had negative correlation between sputum and FEF(200-1200ml).

PURPOSE: To investigate the etiologic microorganisms of external ventricular drain (EVD)-related ventriculitis and the appropriateness of using ceftazidime and vancomycin as an empiric therapy in neurosurgical patients with EVD-related ventriculitis. MATERIALS AND METHODS: Retrospective analysis of 39 patients with EVD-related ventriculitis among 340 neurosurgical patients to whom EVD had been placed during December 2000 and October 2003 at Kyungpook National University Hospital. RESULTS: Thirty-nine EVD-related infections (39/340, 11.5%) occurred and the attributable mortality rate was 10.3% (4/39). The average duration from the ventricular catheter placement to the development of ventriculitis was 8.4 days. All patients with EVD infection had fever and 89.7% (35/39) of the patients showed nuchal rigidity. The positive culture rate in CSF was 87.1% (34/39) and the frequency of individual organism is as follows:Acinetobacter 45% (19 cases), methicillin-resistant coagulase negative Staphylococcus 22% (9 cases), methicillin-resistant Staphylococcus aureus 22% (9 cases), Enterococcus 5% (2 cases), Streptococcus pneumoniae 3% (1 case), non-fermenting gram-negative bacilli 3% (1 case). The polymicrobial infection rate was 15.4% (6/39). Among 19 cases of Acinetobacter infection, 42.1% (8/19) of the strains showed resistance to ceftriaxone and 15.7% (3/11) to ceftazidime. However, all cases were sensitive to meropenem. CONCLUSION: These findings show that the major etiologic organisms causing EVD-related ventriculitis have recently changed to Gram-negative non-fermenters, especially Acinetobacter. Because Gram-negative non-fermenting rods resistant to ceftazidime are increasing, an immediate change from ceftazidime plus vancomycin, the widely accepted empiric antibiotic therapy, to meropenem plus vancomycin should be considered when clinical symptoms and signs show no improvement or even deterioration.

Tuberculosis of the skull bone tuberculosis is a very rare disease. We report a case occurring in a 52 year-old male was referred to us because of headache and painful swelling in the right frontal area. Plain chest x-ray revealed fibrous, streaky, nodular, patchy opacities in the LUL together with pleural effusion. Plain skull x-ray and CT scan demonstrated osteolytic lesion in the right frontal bone; scanning showed hot uptake by the right frontal area, and this corresponding to skll findings revealed by plain film. After frontal craniotomy the involved bone flap and epidural abscess were removed. Pafthologically, typical granulomatous inflammation was seens; this was composed of caseation necrosis, epithelioid cells and surrounding lymphocytes and plasma cells.

PURPOSE: The aim of this study was to establish a simple formula to predict renal length in children using a Technesium-99m dimercaptosuccinic acid (DMSA) scan data, and to compare it with the formula derived from ultrasonography, which is widely accepted. METHODS: Children who underwent a DMSA scan and ultrasonography were reviewed retrospectively, and those who had anatomical urinary tract abnormalities or urinary tract infections were excluded. RESULTS: A total of 230 children (84 males and 146 females; age, 1 month to 16 years; mean age, 16.8 +/- 27.4 months). Mean renal length measured by DMSA scan was longer than that by ultrasonography (6.38 +/- 1.16 vs. 6.02 +/- 1.14 cm; P < 0.001). Renal length was correlated with age, weight, height, and body surface area on the DMSA scan and ultrasonography, and showed the strongest positive correlation with height. The following formulae were established to predict renal length: mean renal length (cm) = 5.433 x height (m) + 2.330 (R2, 0.833) using the DMSA scan data, and mean renal length (cm) = 5.367 x height (m) + 2.027 (R2, 0.853) using ultrasonography data. CONCLUSION: We propose a simple height-based formula to predict renal length in children using a DMSA scan data, and validate it by comparing with ultrasonography formula.

The purpose of this study was to estimate the national prevalence of childhood asthma and other allergic diseases in Korea, and to determine potential risk factors for the diseases. Stratified random samples of 42,886 were selected from 34 elementary (6-12 yr olds) and 34 middle schools (12-15 yr olds) nationwide, and 38,955 were in the final analysis. The Korean-translated modified version of the International Study of Asthma and Allergies in Childhood questionnaire was used in this cross-sectional survey. Twelve-month prevalences of the symptoms of asthma, rhinoconjunctivitis, and flexural eczema were 8.7%, 10.5%, 7.3% in 6-12 yr olds, and 8.2%, 10.0%, 3.9% in 12-15 yr olds, respectively. For allergic conjunctivitis, food allergy, and drug allergy, the prevalences in 6-12 yr olds were 11.2%, 6.5%, and 1.5%, respectively. Asthma and flexural eczema decreased significantly with age. Other significant risk factors were also noted. For 6-12 yr-old asthma, adjusted odds ratio (aOR) of body mass index was 1.21 with 95% confidence interval (CI) 1.0-1.48, aOR of passive smoking was 1.37 with 95%CI 1.24-1.51, aOR of carpet use was 1.28 with 95%CI 1.10-1.49. For 6-12 yr-old eczema, aOR of affluence was 1.22 with 95%CI 1.07-1.39. The control of obesity and passive smoking would be the most important preventive measures of allergic diseases.
