The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

Liver function tests before treatment showed abnormalities of liver function tests during treatment, while 15(68. 2%) of 22 patients who had abnormal liver function tests before treatment showed abnormalities during treatment. In 12 of the 25 patients who showed abnormalities of liver function tests during treatment with allopurinol, allopurinol was stopped and all patients showed improvement of liver function tests. In remaining 13 patients, 10 patients were improved and other 2 patients showed only mild abnormalities of liver function tests despite of continuing allopurinol and 1 patient was lost during follow-up. CONCLUSION: Abnormalities of liver function tests were common during treatment with allopurinol. Most patiensts who had mild abnormalities of liver functions tests during treatment with allopurinol were improved regardless of continuing allopurinol.

BACKGROUND/AIMS: p53 mutation is the most common genetic abnormality in human cancers. However, although it has been reported that p53 overexpression in hepatocellular carcinoma (HCC) is associated with the aggressive behavior of tumor, the prognostic significance of p53 overexpression in HCC remains controversial. The aims of the present study were to examine the correlations between p53 overexpression and the clinicopathologic parameters of HCCs, and to determine the prognostic significance of p53 overexpression in HCC. METHODS: Immunohistochemical analysis of p53 overexpression was performed in 105 consecutive cases of HCC who underwent curative hepatic resection. Survival curves were calculated using the Kaplan-Meier method and multivariate analysis of outcome predictors for HCCs was assessed by logistic regression analysis. RESULTS: p53 overexpression was observed in 20 of 105 HCCs (19.0%). Multivariate analysis identified significant correlations between p53 overexpression and microvascular invasion (p=0.027), liver cirrhosis (p=0.035), 1-year survival rate (p=0.016), multiple tumors (p=0.014), and the presence of tumor capsule (p=0.010). The 2-year survival rate was poorer in patients without tumor capsule (p=0.043). CONCLUSIONS: Our results show a positive association between p53 overexpression and microvascular invasion in HCC, and indicate that p53 overexpression is a poor prognostic factor of survival, especially within 1 year after liver resection in HCC patients.

17 cases of acute myocardial infarction with no or insignificant narrowing of major coronary arteries on angiogram and without any-other types of heart disease were found in a series of 133 consecutively studied patients with acute myocardial infarction(12,7%). There were no differences in risk factors between groups. Although the infarction site were similar in both groups, the patients with normal coronary arteries had fewer complications during hospitalization(p<0.05) and lesser ST segment change during the exercise test before discharge(p<0.05). In the hemodynamic fingings, cardiac index, left ventricualr and diastolic pressure and resional wall motion were similar in both groups of the patients, but ejection fraction was higher(p<0.05) in the patients with the normal coronary arteries. In conclusion, it could be predicted that the acute myocardial infarction with the normal coronary arteries would have the better prognosis. And a transient coronary occlusion, as the most likely pathogenic mechanism of the acute mtocardial infarction with normal coronary arteries, might be studied in the aspect of the thrombosis following lysis, the coronary artery spasm and the platelet aggregation.

Low back pain in computer terminal operators is a very common but important symptom. While the occupational risk factors of low back pain were approved obscurely, there have been few studies on analysis or understanding of occupational risk factors. Therefore, we studied occupational risk factors of low back pain, especially for ergonomic factors as well as general characteristics of workers. We selected 98 subjects for this study, computer terminal operators ordinary using computers in Pusan. We calculated the subjective severity of low back pain of each operator by the Low Back Pain Scoring System. The relation of low back pain score to general characteristics of worker was also analyzed. We analyzed the relationship between low back pain score and individual efforts to prevent low back pain. We measured the ergonomic factors of each computer terminal operator - Trunk Jnclination(TI), Arm Flexion(AF), Elbow Angle(EA), Head Tilting(HT), Knee Angle(KA), using of foot plate and gap between the popliteum and chair. The correlations between these ergonomic factors and low back pain score were then analyzed. And the results are as follows: 1. The prevalence rate of low back pain in computer terminal operators was 39.8% in this study, when low back pain score was converted by the low back pain scoring system. 2. According to general characteristics of workers related to low back pain, the scores were higher in the older age group, the married and the longer work carriers. (p < 0.05) 3. In the analysis of the relationship between low back pain score and individual effort to prevent low back pain, regular exercise, history of schooling for prevention of low back pain, and declaration of intention to participate in low back pain education or exercise were stastistically significant(p < 0.05). And the more severe the low back pain, the higher the intention to participate in low back pain education they had in this study. 4. In the analyses of relationships or correlations between low back pain score and each of the 7 categories of ergonomic factors, only head tilting had a weak reverse correlation with low back pain(r=-0.2999, p < 0.01). From now on, cohort studies for the risk factors of low back pain of workers, who have been forced to work in non-ergonomical positioning at the work site, will be necessary. On the background of these ergonomic studies, the occupational health profession should be required to manage ergonomic working conditions.

The intestine is the third most commonly injured abdominal organ in blunt trauma. But we had a paucity of experience with these injuries. We experienced bowel ischemia in 55 year-old woman after motor-vehicle accident. She complained nausea, vomiting and weight, loss after traffic accident. We found mucosal hyperemia and intraluminal stenosis of duodenal second portion by the gastroscopy. So, we performed hypotonic duodenography and SMA and celiac angiograpby. Hypotonie duodenography showed a luminal narrowing from duodenojejunal junction to proximal jejunum and proximal dilatation, and SMA angiography showed 10 cm segment hypervascular staining of contrast medium in proximal portion. Therefore we performed jejunal loop segmentectomy. After operation she was discharged without complication.

Malakoplakia is an uncommon granulomatous disease most frequently found in the bladder or ureter. Howevcr, it has been reyorted in almost every ather organ and structure, the colon is the most common site of malakoplakia outside the urogenital tract and colonic carcinoma is the most commonly associated disease. A case of malakoplakia of the colon in a 54-year-old female is reported. Sigmoidoscopy revealed multiple whiteyellowish nodules simulating polypoid lesion at 10cm from the anal verge. The biopsy showed characteristically comprised submucosal proliferations of histiocyte and chronic inflammatory cells with typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Intravenous pyelogram showed no evidence of involvement of the urinary system. These nodules were removed by endoscopic polypectomy, So far, this is the first case of isolated colonic malakoplakia in Korea.
