OBJECTIVES: Health care workers(HCWs) are more likely to become infected with tuberculosis from patients in the hospital. When HCWs have an active tuberculosis infection, it is possible that they also become a source of infections to other HCWs and patients. METHODS: Tuberculin tests were performed with mantoux method using 5 units of tuberculin by infection control practitioners on Feb. 21, and Mar. 7, 1997. A total of 138 newly employed HCWs including 44interns and 94 nurses were tested. Results of skin test were interpreted by themselves according to the instructions. RESULTS: Among 138 personels, skin tests were negative in 27 personels (19.6%); 4 interns (9.1%) and 23 nurses (24.5%). There were 3 persons (2.2%) who had a history of tuberculosis which had been treated. CONCLUSION: The study showed that approximately 20% of newly employed HCWs had negative tuberculin skin test. Given the possibility of being infected with tuberculosis in the hospital, regular follow up of tuberculin skin test is warranted to protect HCWs,

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

Functional magnetic resonance imaging is a promising imaging technique developed recently to obtain functional maps of the brain, and can be successfully performed on widely available diagnostic MR imaging systems. Thus, the technical principle and application of this new imaging are no more minor part of knowledge in radiology. We describe herein the overview of functional magnetic resonance imaging about the physiologic mechanism, imaging technique, image-processing method and practical application.

CT scan is widely used in the evaluation of hepatobiliary system and contrast study is generally performedwith non-biliary contrast media. Therefore the normal intrahepatic bile ducts are not readily visible and alsoextrahepatic bile ducts are occasinally not discriminated from adjacent structures, in spite of improvedresolution of the CT scanner. This study was performed to evaluate the usefulness of cholangiographic enhancementin biliary CT examination. In the control group (n=5), we measured the CT number of the peripheral hepatic duct,perioportal duct, common bile duct and gall bladder, respectively, at the interval of 30 minutes upto 2 hoursafter intervenous infusion of biliscopin(30ml) and observed time-denstiy relationship of infused biliscopin in thebiliary system. In the patient group (n=23), we observed visualization rate of the bilary system and serumbilirubin level at 30 minutes after infusion of biliscopin(30ml). The results were as follows: 1. The peak densityoccurred at 30 minutes after infusion of biliscopin. 2. Visualization rate was 100% in normal bilirubin groupwhereas it was 91.7% in abnormal bilirubin group. 3. The cholangiographic enhancement of biliary CT scan is usefulin the evaluation of intra-and extraheptaic biliary system.

An experimental study on the effect of the induced dislocation of the femoral head on the femoral anteversion was made in the hips of 55 rabbits, three to four weeks old. The results were as follows; l. In 49 of the 55 operated rabbits, a relative increase of anteversion was observed on the dislocated side, as compared with the nonoperated femur, the differences ranging from 3 to 55 degrees with an average of 20.0 degrees. 2. The anteversion angle of dislocated hip showed steady and gradual increase with the increase of age. 3. The anteversion increase was detected very early after operation; 3 of the 4 rabbits, belonging 4 to 7 days group after operation showed the anteversion increase. 4. The collapse of proximal femoral epiphysis was observed in 42 of the total 55 hips. The incidence of the collapse was higher in postoperative 4 weeks and more groups. 5. The color change, pale discoloration, of the articular cartilage was observed in 32 of the total 55 hips. The icnidence of pale discoloration was higher in the groups within 8 weeks after operation.
