Introduction: Several investigators demonstrated that routine nasogastric decompression after abdominal surgery was unnecessary and can be safely eliminated. Some authors suggested that early feeding could be tolerated by the majority of patients after elective colorectal surgery. PURPOSE: The aim of our study was to prospectively assess the safety and tolerability of early oral feeding after colorectal surgery. METHODS: This trial included 69 patients who underwent an colon or rectal operation between April 1997 and August 1998. Patients were randomized after the operative procedure into one of two groups. Group 1: early oral feeding-all patents received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated. Group 2: delayed feeding-all patients were treated in the traditional way with feeding only after the resolution of their postoperative ileus. Both groups had intraoperative nasogastric tubes that were removed at the end of surgery. The patients were monitored for vomiting, nasogastric tube reinsertion, time of regular diet consumption, complication, and length of hospitalization. The nasogastric tube was reinserted if two or more episodes of vomiting of more than 100 ml occurred in the absence of bowel movement. RESULTS: Sixty-nine consecutive patients were studied, 34 patients in group 1 (12 males and 22 females, mean age 58.1+/-12.7), and 35 patients in group 2 (16 males and 19 females, mean age 58.5+/-12.7). Significant differences were not noted in age and type of procedures. No significant differences were seen in rates of vomiting and overall complications. However, early feeding group well tolerated a regular diet (postoperative period to take regular diet of group 1: 5.4+/-4.0 days, group 2 : 8.1+/-4.6 days, p=0.013), and were discharged from hospital significantly earlier than the delayed feeding group(group 1: 14.0+/-5.1 days, group 2: 19.1+/-8.6 days, p=0.004). CONCLUSION: Early feeding after colorectal surgery is successfully tolerated by the majority of patients and led to earlier hospital discharge.

Nickel is widely known as a common source of contact dermatitis and nickel sensitivity amounts to nearly 10 percent of allergic contact dermatitis patients. Common sources of nickel dermatitis are well known as necklaces, watches, rings, hooks, earrings and spectacle frames. Recently, we have seen five cases of nickel dermatitis the suspected sources of which were metal spectacle frames. The interim patch test result in our occupational and environmental clinic suggests that the metal spectacle frame is one of the most common sources of nickel dermatitis. Out of 84 medical students 27 wore metal spectacle frames. We have done a dimethylglyoxime spot test to the metal spectacle frames and got a positive result in 12 out of 27(44.4%). We conclude that metal spectacle frame seems to be one of the dominant causes of nickel dermatitis and it will be an increasing problem in our society.

We evaluated the clinical manifestations of 326 patients of vitiligo who had visited Seoul National University Hospital. The results were as follows : 1) There were 141 males (43.3%) and 185 females (56.7%). 2) The mean age of onset was 19.6 years (male : 18.3 years, female : 20.6 years). 3) The mean age at the first visit wss 23.9 years (male : 22.5 years, female : 24.9 years). 4) Duration of disease was less than 2 year in 156 patients (47.9%). 5) The most common site of initial involvement was face (36.2%). The common sites of involvement were face (55.2), abdomen (32.5%), neck (26.7%) and scalp (24.8%) in decreasing order of frequency. 6) There were 167 cases (51.2%) of generalized type, 118 cases (36.2%) of localized type, 31 cases (9.5%) of dermatomal type and 10 cases (3.1) of halo nevus. The most frequent site of dermatomal type was neck. Gray hair was noted in 91 cases (27.9%) and mucosal involvement was present in 43 cases (13.2%). 7) Family history was obtained in 24 cases (7.4%). Koebner phenomenon was present in 48 cases (14%). There were no precipitating factors in 309 cases (94.8%) prior to development of vitiligo. 8) The associated diseases were 1 csse of thyroiditis and 3 cases of alopecia areata.

To clarity the effect of biliary obliteration on copper metabolism of rat liver and on the hepatic morphology, 0.5% cuppuric sulfate was administered intraperitoneally for 42 days following ligation of the common bile duct (CBD) of Sprague-Dawley rats. The blood copper concentration, the hepatic copper content and the accumulation patterns of copper and copper binding protein in the liver were examined and compared with those of the simple CBD ligation group and the simple copper over loaded group. CBD ligation induced marked proliferation of bile ductular structures which, after expanding the portal tracts, invaded and divided the hepatic lobules. There was, however, no excess fibosis beyond what needed to support the new ductules. The blood copper concentration and the hepatic copper content were increased by copper overload with or without CBD ligation, particularly incases with CBD ligation. Liver cell necrosis did not occur by the overloaded copper alone in rats. The hepatic copper and copper binding protein were accumulated at periportal liver cells in the group of coppe overload after CBD ligatio, whereas they began to appear at perivenular hepatocytes in the simple copper overloaded group. In conclusion, it is suggested that CBD ligation does not induce excess fibrosis or liver cirrhosis in rat as far as during our experimental period, but affect significantly on copper metabolism by intrahepatic redistribution of the copper and the copper binding proteins.

Solar urticaria is a rare skin disease characterized by urticarial reactions immediately following exposure to sunlight or artificial radiation. A 24-yr-old man had solar urticaria that was activated by visible light. Positive result of passive transfer of the reactivity with the patients serum to the skin of normal recipient suggested that his condition was attributable to an allergic response. Result of reverse passive transfer studies was negative. We report a case of solar urticaria which appeares to belong to type N in the classification of Harber.
