Rectal Prolapse*

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: 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.

PURPOSE: We wanted to evaluate the value of intravenous contrast enhanced abdomen-pelvis computed tomography (CT) for diagnosing acute appendicitis and we wanted to determine which patients groups will benefit from preoperative CT. METHODS: Between January and June 2006, the medical records of 354 patients who had clinically suspected acute appendicitis were retrospectively reviewed. Appendectomy was performed in 260 patients and CT was conducted in 108 patients of the 260 patients. The 5mm slice CT scans were evaluated for the presence of appendicitis. The sensitivity, specificity and accuracy of CT were calculated. The negative appendectomy rate (NAR) was compared between the patients with CT scans and those without CT scans. Furthermore, the patients were classified into the children and adults groups and the male and female groups and the differences of the NARs were analyzed for each group. RESULTS: The sensitivity, specificity and accuracy were 95%, 93% and 94%, respectively. The NAR was lower for the patients with a CT scan (12%) compared to 27% for those patients without CT scans (P=0.002). The difference of the NAR between the preoperative CT group and the without CT group was statistically significant for the female (P=0.004) and adult groups (P=0.012) (14% vs 36%, 11% vs 26%, respectively). CONCLUSION: Preoperative intravenous contrast enhanced abdomen-pelvis CT was effective in reducing the negative appendectomy rate in patients who were suspected of having acute appendicitis. Especially, the adults and women benefit more from CT scanning and they had a significantly lower negative appendectomy rate than the children and men, respectively.
