PURPOSE: A study was performed to compare the detectability of extrahepatic duct stones between nonenhanced and enhanced computed tomography(CT). MATERIALS AND METHODS: Consecutive 30 patients with extrahepatic duct stones were analyzed with special attention to the detectability of stones between nonenhanced and enhanced CT. The extrahepatic duct was further divided into two segments, one above(suprapancereatic) and the other in(intrapancreatic) the head of the pancreas. Conspicuity of the stone was graded as "visible", "suspicious", and "invisible". Three radiologists reviewed the CT images without prior information and determined the location of stone and grade of their conspicuity. RESULTS: The stones were located at the suprapancreatic common duct in 5 patients, intrapancreatic common duct, in 15 patients and both portion of the duct in 10 patients. There was no difference in the detection rate of stones between the two images at suprapancreatic common duct, and was 93%, However, the rate at intrapancreatic common duct was 95% and 64% on nonenhanced and enhanced CT scans, respectively. The overall detection rate was 95% on nonenhance CT and 75% on enhanced CT. CONCLUSION: We concluded that nonenhanced CT was prerequisite to evaluate the extrahepatic duct stones in addition to enhanced CT.

1795 patients who visited orthodontic department from 1979 to 1987, were surveyed on the yearly tendency of patient distribution and state of Angle's classification. The results were as follows; 1. There was increased visiting rate of patient per year and higher visiting rate in female than in male. 2. 8-15 age group was 70.3% in total visiting patients and over 20 age group was 10.8%, under 7 age group was 7.3%. 3. Class I malocclusion was 26.3%, Class II div 1 was 31.0%, Class II div 2 was 1.6% and Class III was 41.1% in total visiting patient. 4. There was increased tendency to be received preventive treatment than fixed treatment and increased extracting rate per year in fixed treatment. 5. There was increased tendency for the number of the patient to be received orthognathic surgery.

PURPOSE: To investigate the efficacy of ultrasound (US)-guided core biopsies after digital mammography-guided two-dimensional localization (DM-2DL) of breast microcalcifications. MATERIALS AND METHODS: Twenty-two patients with 23 suspicious microcalcifications underwent US-guided core biopsies after DM-2DL, to mark the sites on the skin where microcalcifications had been found (craniocaudal and mediolateral (or lateromedial) views). Of the 23 lesions, 4 were sampled using a 14-gauge automated gun and the other 19 were sampled using an 8-gauge vacuum-assisted device. The lesions were categorized into two groups: those with and those without microcalcifications observed on US. The success rate for correctly sampling microcalcifications on the specimen radiograph in the two groups was assessed and their pathologic outcomes were investigated. RESULTS: Of the 23 lesions, 16 were invisible and 7 were visible to ultrasonographic microcalcifications. The sampling success rate for the specimen radiographs was 100% for ultrasonographic visible microcalcifications and 88% (14/16) for lesions invisible to ultrasonography after DM-2DL (p = 1.000). The cancer rate of individuals with microcalcifications observed on US (57%, 4/7) was greater than in individuals without visible microcalcifications (13%, 2/16) (p=0.045). CONCLUSION: Although some microcalcifications are invisible on US, a US-guided biopsy after DM-2DL is a useful method for the successful sampling of the microcalcifications.

In the evaluation of the source of occult bleeding, it is mandatory that the small bowel be investigated. But, the small bowel is the area where endoscopic approach is most difficult. The endoscopic evaluation of the small intestine has rapidly evolved over the last 10 years and now includes many of the diagnostic and therapeutic capabilities of standard endoscopic procedures. Various techniques have been developed, including fiberoptic sonde enteroscopy, retrograde ileoscopy, intraoperative enteroscopy, "push" enteroscopy using a pediatric colonoscope, and video enterocopy. Therefore, the small bowel enteroscope has shown great promise in the evaluation of obscure or persistent gastrointestinal bleeding. We have experienced a case of bleeding from jejunal leiomyosarcoma, which diagnosed with small bowel enteroscopy. So we report the case with a brief review of literature.

Duodenal tumor is relatively rare disease, accounting for about 0.3% of all carcinomas of the gastrointestinal tract. Although radiological and endoscopic examinations have become popular, we are not so familiar with the duodenal tumors as those of the other gastrointestinal tumors. The absence of precise symptoms and the rarity of primary malignant neoplasms in this localization are frequently the reason for the late diagnosis. And so, often the true nature and localization of the tumor are only determined during surgery or autopsy. But, recently, duodenal bulb is examined with ease and pathologic diagnosis is possible following the diffusion of panendoscopy. We have experienced three cases of primary duodenal bulb carcinoma, which diagnosed by biopsies with gastrofibroscopic endoscopy. So we report the cases with a brief review of literature.
