Inflammatory polyposis of the colon is rare portion of the colon polyp entity. We experienced three patieats who suffered from colitis of unknown'etiology and discovered membranous retkular with/ without filiform polyp in the distal sigmoid colon of the them. Case 1, 56-year-old female, combined with basaloid cercinoma of the rectal canal that confirmed by pathology after abdominoperineal resection. So we obtained specimen of inflammtory polyp end tried to evaluate the mechanism of it. We found healed ulcer under the mucosal bridge. Case 2. 55-year-old male, had been suffered from irritable bowel syndrome. Prior to visit outpatient clinic, he complained tenesmus with diarrhea for a week. Inflammatory polyp was discovered by colonoacopy but his symptoms relieved by tranqulizers only. Case 3. 57-year-old male, has been a good health. He undertook colonoscopy for routine check thst revealed membranous reticular with filiform inflammatory polyp from distal sigmoid colon to hepatic flexure. Such shape of inflammatory polyp was not documented in Korea, so we reported three cases of it with review of the literature.

Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to theantibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necroticfoci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to thecausative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certaincharacteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate theclinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms.

The purpose of this study was to evaluate the reliability of 6-axis model surgery simulator (6AMSS) for orthognathic surgery. A rectangular parallelepiped plastic block was assembled to model-mounting plate of 6AMSS. Left-right (X), anterior-posterior (Y), up-down (Z) translation and pitching (empty set X), rolling (empty set Y) and yawing (empty set Z) rotation was planned and performed using 6AMSS. The actual translation and rotation were measured with dial gauge and precisional protractor, respectively. Comparison between the planned and actual movements of plastic block for each variable were made using paired t- test. Statistical analysis for X, Y, Z, empty set X, empty set Y and empty set Z movement have shown no significant differences between planned and actual movement (P > 0.05). This indicate that model surgery performed with the aid of the 6AMSS is accurate in 3D translation and rotation. The 6AMSS is practically useful for accurate fabrication of surgical splint for orthognathic surgery.

PURPOSE: To differentiate tuberculous enteritis and Crohn's disease with barium study using Bayes theory. MATERIALS AND METHODS: The study group consisted of 34 patients with tuberculous enteritis (age range 16-86 years, mean age 43.3 years, M:F=19:15) and 36 patients with Crohn's disease (age range 19-78 years, mean age 35.2 years, M:F=18:18). These diagnoses were confirmed by therapeutic tests (tuberculous enteritis: 15, Crohn's disease:16) or histopathological examinations (tuberculous enteritis: 19, Crohn's disease: 20) conducted from January 1993 to May 2003. Three radiologists (two abdominal specialists and one trainee) analyzed each radiological finding of tuberculous enteritis and Crohn's disease by means of a barium enema and/or small bowel series. We used Fisher's exact test to verify the statistical significance of each radiological finding and p-values less than 0.05 were considered to be significant. We calculated the likelihood ratio (LR) of tuberculous enteritis versus Crohn's disease for each finding by employing Bayes theory. RESULTS: The radiological findings associated with a high likelihood ratio for tuberculous enteritis were the involvement of the cecum (LR=2.65) and ascending colon (LR=1.99), rigid narrowing (LR=1.94), shortening of the bowel (LR=1.99), haustral loss (LR=1.97) and sacculation (LR=3.88). The radiological findings associated with a high LR for Crohn's disease (low LR for tuberculous enteritis) were age between 20 and 29 years (LR=0.53), the involvement of the jejunum (LR=0.12), terminal ileum (LR=0.19), sigmoid colon (LR=0.30) or rectum (LR=0.17), and the presence of skip lesions (LR=0.19) or strictures (LR=0.21). With these LRs, the probability of the subject having tuberculous enteritis versus Crohn's disease could be calculated using Bayes theory. CONCLUSION: The analysis of a barium study using Bayes theory could provide an objective, easy and fast method of differentiating tuberculous enteritis and Crohn's disease.

PURPOSE: Smoking elicits airway inflammation and airflow obstruction in patients with asthma, even after smoking cessation. The aim of this study was to examine the effects of smoking cessation on lung function and quality of life (QOL) in asthmatic patients. METHODS: Thirty-two patients with asthma who were active smokers were recruited. After education on the effects of smoking on asthma, 22 patients continued to smoke, and 10 quit smoking. All patients were treated with inhaled fluticasone propionate (1 mg/day) for 3 months. We compared forced expiratory volume in 1 s (FEV1), FEV1/forced vital capacity (FVC), forced expiratory flow between 25 and 75% FVC (FEF(25-75%)), and scores on a QOL questionnaire at baseline, 1, 2, and 3 months. RESULTS: Quitters showed a greater percent change in FEV1 (19.1+/-6.3 vs. 7.9+/-2.4%, P=0.024) and FEV1/FVC (6.5+/-4.14 vs. 3.5+/-1.5%, P=0.05) than smokers. Both quitters and smokers showed improved QOL scores after 1, 2, and 3 months of fluticasone treatment. CONCLUSIONS: Patients with asthma who quit smoking showed less airway obstruction, suggesting that smoking cessation is crucial in the management of asthma.
