- BACKGROUND
There are two theories in the development of colon cancer. One is the adenoma-carcinoma sequence theory and the other is the de novo cancer theory. Western countries believe in the adenoma-carcinoma sequence theory, however there are many recent reports from Japan about cancers developing from small adenomas. METHODS: The present study analyzed 408 polyps from 508 cases that were taken by colonoscopic polypectomy at the Departmant of Internal Medicine, Yeung-Nam University Hospital. RESULTS: The percentage of patients who have polyp was 41.3%(210cases out of 526cases) and the peak incidence was noted in patients in their 50's and 60's. There was no difference between the sexes, but we noted significant increase in the incidence of polyps in patients over age of thirty. We found 395 polyps below 1cm and 13 polyps above 1cm. Among 408 polyps, 5 cases cancerous polyps and 3 cases showed polyp size of less than 1cm each. The first case was a polyp of 0.4cm in size with elevated mucosa at the ascending colon. The second was 0.5cm in size with round elevation and hyperemic mucosa in the rectum. The third polyp was 0.6cm in size with tubular elevation at the hepatic flexure. CONCLUSIONS: colon polyp is common disease in Koreans. even small polyps can have cancer tissue, which should be removed if discovered during colonoscopy. We believe that not all colon cancer originates in the manner described by the adenoma-carcinoma sequence theory. However further studies with a larger sample population are needed to determine the exact role colon polyps plays in the development of colon cancer.

- Sparfloxacin is a new synthetic quinolone antimicrobial developed at the Research Laboratories of Dainippon Pharmaceutical Co, Ltd. To evaluate the efficacy and safty of sparfloxacin in acute pulmonary infection, we administered sparfloxacina(100mg) twice in a day to 30 patients who had sign and symptoms of acute pulmonary infectious diseases regardless of their underlying lung disease for 7 days. The results were : 1) A total 30 patients were enrolled in the trial. Among them 24 cases(80%) had underlying lung problems such as chronic obstructive pulmonary disease(36.4%), bronchiectasis(36.4%), bronchial asthma(3.3%), lung cancer(3.3%). 2) In 26 cases(86.6%), we observed effective improvement, and 4 cases(13.4%) show mildly effective improvement of symptoms and signs of respiratory infection. 3) In 23 cases(73.4%), we observed bacteriological eradication in culture or decreased the number of bacteria in Gram stain which found dominantly in previous Gram stain. 4) The significant side effect was not noted. The above results suggest that sparfloxacin was effective as a first line therapy in patients with acute respiratory infection.

- To evaluate the efficacy and safety of clarithromycin in acute exacerbation of chronic obstructive pulmonary disease, we administered clarithromycin(250mg) twice in a day in 30 patients with acute exacerbation of chronic obstructive pulmonary disease from September to November in 1996. Twenty eight eases of 30 patients were cured(93.4%) and 2 cases(6.7%) show clinical improvement. Three cases were improved within 3 days of treatment and 24 cases were improved between 5 days and 12 days of treatment. There were no significant side effects. These results suggest that clarithromycin will be effective as a first line therapy in patients with acute exacerbation of chronic obstructive pulmonary disease.

Abstract

- Adenoid cystic carcinoma is an uncommon histologic variant of adenocarcinoma which usuallyy arises from the salivary, lacrimal, or other exocrine glands. Characteristics of adenoid cystic carcinoma are its potential fo extending long distance submucosally and for perineural invasion. It grows slowly and may have a prolongec course before diagnosis and after treatment. Recently, we have experienced 2 cases of adenoid cystic carcinoma arising from main bronchus and trachea. One case was 58 years old female patient. Her symptoms were productive cough with dyspnea. She ha been history of shortness of breath, wheezing and cough during 4 years, which was initially diagnosed a bronchial asthma. The tumor was located on the left main stem bronchus which was obstructed the lumei nearly complete, by CT demonstration.
