PURPOSE: To evaluate the effectiveness and the most accurate element of the diagnostic criteria of the Japan Society of Uitrasonics in medicine(JSUM, Nov. 1989) for distinguishing between benign and malignant solid breast masses on the US. METHODS AND MATERIALS: We analyzed the ultrasonic findings of histopathologically proved 51 fibroadenomas, 12 fibrocystic disease, and 39 breast cancers in relation to the diagnostic criteria of the JSUM (shape, border, boundary echo, internal echo, posterior echo, lateral echo, and depth/width ratio). RESULTS: The number of cases of fibroadenoma, fibrocystic disease, and breast cancer corresponding to the diagnostic criteria was in the shape(26/51, 5/12, 33/39), border(41/51, 9/12, 29/39), boundary echo(48/51, 12/12, 27/39), internal echo(43/51, 9/12, 24/39), posterior echo(32/51, 3/12, 21/39), and lateral shadowing(15/51, 1/12, 35/39). All diagnostic criterias showed statistical significance for differentiation of benign/malignant breast mass on the US(Chi-square test: p<0.05). The order of accuracy was boundary echo, internal echo, and border. The mean of depth/width ratio was 0.54 +/- 0.15, 0.52 +/- 0.12, and 0.69 +/- 0.21 in fibroadenoma, fibrocystic disease, and breast cancer respectively and it had statistical significance for differentiation of benign/malignant breast mass on the US(ANOVA test: p=0.0002). CONCLUSION: The diagnostic criteria of JSUM is effective for differentiation of benign/malignant breast solid masses on the US and has accuracy in the order of boundary echo, internal echo, and border. Depth/width ratio also has statistical significance.

Journal of the Korean Radiological Society 1995;32(4):557-562
PURPOSE: To evaluate types of gray matter heterotopias, associated brain anomalies, and its correlation with the patterns of seizure. MATERIALS AND METHODS: We evaluated retrospectively 19 patients(male :female=10:9, mean age 21 years) with gray matter heterotopias on brain MRI. Using 1.0T superconducting MR unit, spin echo TI-, proton-density- and T2-weighted images in axial, coronal and sagittal planes were obtained. RESULTS: Types of gray matter heterotopias were single subependymal in four patients, multiple subependymal in one, focal subcortical in eight, diffuse subcortical in two, mixed multiple subependymal and focal subcortical in four. Associated anomalies were seen in 11 patients:other neuronal migration anomalies in eight patients, corpus callosum agenesis in two, and combined holoprosencephaly and Dandy-Walker malformation in one. Fifteen patients had seizure. The patterns of seizure were not correlated with the types of heterotopias. CONCLUSION: In addition to subependymal, focal subcortical, and diffuse subcortical types, gray matter heterotopias included mixed variant of of multiple subependymal and subcortical type. Schizencephaly was the most common form of accompanying anomalies, and patterns of seizure were not correlated with types of gray matter heterotopias, even though main clinical menifestation was seizure.

Annals of Dermatology 1997;9(1):36-40
Subcutaneous fat necrosis of the newborn is an uncommon disorder characterized by firm b-cutaneous plaques and nodules usually appearing shortly after birth. It runs a relatively be, n course and may completely resolve in a few months without any recurrence. We report a case of subcutaneous fat necrosis in a 15 day-old male suffering from severe p inatal asphyxia and hypoxic cardiomyopathy, who presented with indurated subcutane s nodules and plaques on the both shoulders and the back. Histologically the subcutaneous fat showed focal necrosis with needle-shaped clefts, lymphohistiocytic infiltration and foreign body reactions consistent with subcutaneous fat necrosis of the newborn. In our patient, compromised cardiac output due to cardiomyopathy might have aggravated hypoxic condition and it could be speculated that cardiomyopathy-induced systemic hypoxia gave rise to hypothermia of the skin as a result of peripheral vasoconstriction. This report presents a causal relationship of cardiomyopathy and subcutaneous fat necrosis of the newborn.

Journal of the Korean Radiological Society 1994;30(5):795-800
PURPOSE: To evaluate the significance of high signal intensity of the septum pellucidum in hydrocephalus on proton density-weighted brain MR images. MATERIALS AND METHODS: Authors reviewed the MR images of 418 cases of patients with normal(175 cases), hydrocephalic(35 cases), atrophic(58 cases), and other groups(150 cases) retrospectively. We analyzed the signal intensity of the septum pellucidum in the normal group and the incidences of high signal intensities of periventricular area of frontal horn of lateral ventricle(area 1), periventricular area except area 1(area 2), callososeptal area(area 3), and septum pellucidum(area 4) in the normal and abnormal groups. RESULTS: In the normal group, the septurn pellucidum was isointense to the head of caudate nucleus on proton density-weighted image. High signal intensity of the septurn pellucidurn was seen in 31 cases (22 cases of hydrocephalus, 5 cases of brain atrophy, and 4 cases of others), and showed high specificity(91.4%) for hydrocephalus in spite of low sensitivity(62.9%), as compared with periventricular hyperintensities of other areas. CONCLUSION: High signal intensity of the septum pellucidum on proton density-weighted image may be caused by transependymal CSF migration in the patients with hydrocephalus, and considered as an additional finding of hydrocephalus in the cases of ventriculomegaly.

We report herein three cases of subcutaneous sarcoidosis without apparent internal lesion. The patients had multiple subcutaneous nodules on the extremities and abdomen. Hyper-gammaglobulinemia, a relative increase of T suppressor cells, and increased serum angiotensin converting enzyme level and skin anergy were observed. Histopathologic findings revealed sarcoidal granulomas involving the subcutaneous fat tissue. The lesions of two cases resolved spontaneously and the other one case required systemic corticosteroid therapy.

In order to investigate working conditions of underground coal mines, this work was undertaken to evaluate the respirable dust and the concentration of quartz in Taeback and Kangneung areas. The concentration of quartz was determined by Fourier Transform Infrared Spectrophotometry. The results were as follows; 1) The concentration of respirable dust of drilling and coal face in Taeback and Kangneung areas were as followed. 2) Distribution of respirable dust was well fitted to the long-normal distribution and geometric mean value was log(-1) 0.37+/-log(-1) 0.47 (2.34+/-2.95) mg/m3. 3) The difference of respirable dust concentrations in Taeback and Kangneung areas was not significant statistically (p>0.05). 4) The concentration of quartz of drilling and coal face in Taeback and Kangneung areas were as followed. 5) Distribution of quartz concentrations was well fitted to the log-normal distribution and geometric mean value was log(-1) 0.33+/-log(-1) 0.45 (2.14+/-2.82)%. 6) The difference of quartz concentrations in Taeback and Kangneung areas was not significant (p>0.05), but significant at drilling sites and coal faces (p<0.05).

Journal of the Korean Radiological Society 1994;31(4):737-742
PURPOSE: Authors analyzed the MR findings of swollen extremities to evaluate the MR features of lymphedema and phlebedema. MATERIALS AND METHODS: We reviewed MR imagings of 17 cases of swollen extremities, including 12 lymphedemas and 5 phlebedemas. We obtained axial TI-, T2-, and Gd-DTPA enhanced T1WIs using 1.0T superconducting magnet and measured cross-sectional areas of subcutaneous and subfascial tissues of a slice with grossly largest cross-sectional area using perimeter. We also analyzed changes in the signal intensities of the subcutaneous and subfascial tissues on T2WI, presence of enhancement on Gd-DTPA enhanced T1WI, and presence of skin thickening. RESULTS: Both subcutaneous and subfascial tissues of swollen extremities were increased in the cross-sectional areas than those of contralateral normal side. The subcutaneous compartment in lymphedema was statistically significantly increased in cross-sectional area than subfascial compartment in lymphedema(p<0.005) and subcutaneous tissue in phlebedema(p<0.05). Increased signal intensities and characteristic "honeycomb appearance" of subcutaneous tissue in the lymphedema were specific findings on T2WI. CONCLUSION: MR imaging was useful and noninvasive method in the diagnosis of swollen extremities. There were increased cross-sectional area of subcutaneous compartment with "honeycomb appearance" in lymphedema and increased signal intensities of both subcutaneous and subfascial compartment in phlebedema on the T2WI.

Journal of the Korean Academy of Rehabilitation Medicine 1999;23(4):695-702
OBJECTIVE: To identify the neurobehavioral impairment in the traumatic brain injured (TBI) patients and to determine the relationship between the neurobehavioral impairment and functional recovery. METHOD: We analyzed and compared Functional Independence Measure (FIM) scores and neurobehavioral psychometry results in 16 patients with severe TBI. The neurobehavioral psychometry tests included Minimental Status Examination (MMSE), Galvestone Orientation and Amnesia Test (GOAT) as screening tools, Korean Wechsler Intelligence Scale (KWIS) for intelligence, Wechsler Memory Scale-Revised (WMS-R) test for memory function, Color Trail test (CTT) 1 and 2 for attention and concentration, Grooved Pegboard Test (GPT) and Finger Tapping Test (FTT) for motor function, Wisconsin Card Sorting Test (WCST) for executive function, and Symptom Checklist-90-Revision (SCL-90-R) for personality. RESULTS: At discharge, neurobehavioral psychometry of the TBI patients showed impairment of the attention and concentration as demonstrated by severe and moderate impairment in CTT 1 and CTT 2, repectively. Memory disturbance was also noted by the result of mental retardation in WMS-R. But GOAT and MMSE showed normal, KWIS was below average. Motor dysfunction was seen in GPT and FTT and mild executive dysfunction in WCST. Functional recuperation was influenced by attention and concentration, as the FIM score has significant correlation with CTT 1 and FTT. CONCLUSION: The TBI patients have the pervasive neurobehavioral impairment, especially severe dysfunction in the memory, attention and concentration. And functional recovery was significantly correlated with attention. The neurobehavioral psychometry will be useful in neurobehavioral evaluation in TBI patients. A further prospective study using Neurobehavioral psychometry would bring a more precise and valuable information.
