PURPOSE: To document the radiologic characteristic findings of atypical ductal epithelial hyperplasia, we analyzed film mammographic, ultrasonographic, and MRI findings of our cases. MATERIALS AND METHODS: We analyzed 23 cases of surgically proven ADH, excluding carcinoma in ipsilateral breast. Presence and pattern of neodensity, microcalcification, and architectural distortion were reviewed on mammography. Echo pattern and ductal parenchymal morphology were analyzed on ultrasonography, and enhancement speed and pattern analysis were performed on MRI. RESULTS: On film mammography, ADH showed tendency of neodensity(10 of 23 cases), m icrocalcification(11 of 23 cases), with less parenchymal distortion of surrounding structures(7 of 23 cases). On ultrasonography, ADH was demonstrated as inhomogenous to intermediate echoic nodule(16 of 20 cases) with ragged border(19 of 20 cases), however, its boundary was thin or nearly absent(16 of 20 cases), and showed smooth ductal echography(11 of 20 cases). Gd-DTPA contrast dynamic MR study showed relatively slow and less enhancement in 4 out of 5 cases, with progressive inclination of the speed curve of enhancement in later period of dynamic study. CONCLUSION: Multimodality image approach is needed for better evaluation of ADH, however, excisional biopsy is recommended for confirmative diagnosis and proper treatement.

A girl aged 18 years and 1 month, had a Angle's Class Iff malocclusion, characterized by anterior crossbite, anterior crowding, and constriction from right lower 2nd p emolar to right lower 2nd molar This ~i5 5s patient underwent scaling and 84148 extraction, and multibanded system was placed. After 14 months, anterior crossbite and crowding was corrected, andbothdental arches were improved. After 6 months from debanding, band space disappeared, and any relapse was not detected.

One hundred forty eight complications in 135 cases of long bone fractures experienced during the period from May 1971 to December 1979, at the Chosun University Hospital and analysed its retrospectively. The results were obtained as follows. 1. The order of incidence of complications were as follows; infection (39.8%), delayed union(23.6%). malunion (13.5%), ankylosis of joint (12.2%). nonunion (8.1%) and peripheral nerve injury (2. 8%). 2. Of all 127 patients, 97 patients were male and 30 patients were female, and 72 patients (56.7%) were cauesd by traffic accidents. The sex ratio between male and female was 3.2: l. 3. The major complications were frequently associated with other fractures and dislocations, brain injuries. 4. Those of open, comminuted fracture and delayed transfer cases to the Orthopedic Surgeon were predisposing factors to development of the severe complication.

PURPOSE: To evaluate the specific findings of infiltrating ductal carcinoma from the ductal carcinoma in situ (DCIS) and to differentiate from the atypical ductal hyperplasia(ADH). MATERIALS AND METHODS: Fifty breast lesions in 48 patients including thirty-six breasts of 36 patients with infiltrating ductal carcinoma, fourteen breasts of 12 patients with DCIS, and nine breasts of 7 patients with ADH were examined with FLASH technique using Gd-DTPA. We evaluated the maximal amount, the speed, and the pattern of enhancement after intravenous injection of Gd-DTPA(0.16mmol/kg body weight). Also we evaluated the diagnostic accuracy in the patients with breast cancer. RESULTS: The maximal amount of enhancement were 1,161.84 +/- 394.44 NU in infiltrating ductal carcinoma, 982.11 +/- 458.35 NU in DCIS, and 1,035.94 +/- 305.20 NU in ADH. The speed of enhancement was 827.33 +/- 384.20 NU within the first 1 minute with a sudden increase in signal intensity after injection and a much slighter in- crease thereafter in infiltrating ductal carcinoma. DCIS showed in creasing signal intensity within the first 2 minutes(749.70 +/- 487.36 NU), and ADH showed significant increased enhancement(765.40 +/- 313.61 NU) at 3 minutes after injection of Gd-DTPA. The patterns of enhancement were focal with irregular margins in infiltrating ductal carcinoma and irregular peripheral enhancement in DCIS and ADH. However, absent or extreme delayed enhancement at the central portion of the tumor was more frequently seen in infiltrating ductal carcinoma rather than DCIS or ADH. CONCLUSION: Gd-DTPA enhanced dynamic MRI was valuable in the diagnosis of breast cancer and in differentiating DCIS from ADH. Furthermore, it was effective in analyzing the extension of breast carcinoma, multiplicity, and bilaterality of breast carcinoma.
