The potential for sebaceous nevi to evolve into secondary benign or malignant EuIror is well recognized. In general, malignant transformation does not occur until postpubertal life. We experienced a case of basal cell epithelioma arising in a nevus sebaceous on a 12-year-old boy´s parietal scalp. We recommended that surgical excision should be undertaken as early as possible to detect the malignant transformation of nevus sebaceous.

Bowens disease is an intraepithelial squamous cell carcinoma. It occur s anywhere on the surface of the body. Bowens disease involving the nail bed epithelium is very rate. Recently, some literatures showed that human papillomavirus is sssociated with squamous cell carcinoma of the finger by in situ hybridization or polymerase chain reaction. A 30-year-old housewife deve]oped longitudinal melanonychia with as imptomatic fissured nail plate on her right third finger. The hiat,ologic specimen showed diffuse anaplastic change confined to the nail bed epithelium. The subungual eyithelium was found to contain human papillomavirus DNA type 31/33/35 with the use of in situ hybridization.

PURPOSE: A common finding of carotid artery on magnetic resonance angiograms(MRAs) is a signal dropout along the posterior wall of carotid bulb due to reverse flow. The purpose of this study is to evaluate variable flow patterns on bifurcated carotid arterial phantoms using steady-state flow. MATERIALS AND METHODS: We designed phantoms of a bifurcated carotid artery with acrylic materials. Flow patterns were evaluated with axial and coronal imaging of MRA(2D-TOF, 3D-TOF), color Doppler imaging, and computational fluid dynamics (CFD) within the phantoms constructed of an automated closed-type circulatory system filled with 4% sugar solution. These findings were compared with findings obtained from normal volunteers. RESULTS: Axial 3D-TOF MRA images exhibited closer resemblance to the contour of the inner wall of phantoms when compared to coronal 2D-TOF MRA imaging. However, 2D-TOF MRA showed good contrast difference of signal intensities between forward flow area and reverse flow area. Dark zones with reduced signal intensities due to reversed flow were separated from the outer wall of the internal and external carotid arteries by a thin layer of forward flow along the wall on the source slice image of MRA. The general hemodynamics of the phantoms on MRA were identical to hemodynamics on color Doppler imaging and CFD. The results obtained with the phantoms matched the findings on normal volunteers. CONCLUSION: Although representations of bifurcated carotid arterial phantoms on axial 3D-TOF MRA were excellent if ideally desinged, the zone of reversed flow could be a significant factor in creating distorted image when the zone of reversed flow contacted directly with curved or deformed arterial wall.

Clinical observations were made on 338 low birth weight infants, who were delivered at Pusan Wallace Memorial Baptist Hospital, during the 3 year periods from 1989 to 1991. The results were as follows; The incidence of LBWI was 5.6% and sex ratio was 1:1.09. Among them AGA was 62.7%. 2) Of all infants, 47.3% were in the birth weight range of 2251-2500 gm and 25.1% were in the gestational age group of 37-38 week. 3) LBWI were most prevalent among mothers under 20 years old and over 41 years old. 4) The Incidence of LBWI was higher in multiparity than primiparity and in multiple pregnancy than single pregnancy. 5) Vaginal delivery was 63.9% and c-section delivery was 36.1%. 6) The order or frequency of the etiology of LBWI was multiple pregnancy, premature rupture of membrane and toxemia. 7) The mortality rate of LBWI was 12.7% and mortality rate by weight-gestational age was lower in AGA group than SGA and LGA group. 8) A Higher mortality rate was noted in the group of lower birth weight infant, and in the group of more shortened gestational age. 9) 48.8% of death occured within ist day of birth. The common causes of death were respiratory distress syndrome, asphyxia, and apnea.

Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of probable autoimmune etiology. The MR images of patients with clinically suspected ADEM were retrospectively reviewed. The clinical symptoms occurred 5 days to 1 month after viral upper respiratory infection (4) and Coxsakie viral infection(1). The symptoms had begun with fever(3), headache(3), sore throat(1), and drowsy mental state (1), which progressed with monophasic course to altered mental change(2), extremity weakness(2), seizure(1) and/or cerebellary symptom(I) MRI findings of ADEM showed patchy(4), nonhemorrhagic(5), asymmetric(5) high signal intensity lesions on T2-weighted images. The number of the lesions was mostly multiple(4). The lesions mainly involved the brain stem(3) and subcortical white matter(3). Follow-up MR images of 13 days to 20 days after high dose steroid therapy showed marked improvement in two of three, which well correlated with clinical manifestations. MR findin of multiple, patchy, nonhemorrhagic and asymmetric lesions in subcortical white matter and brain stem on T2-weighted images seem to be characteristic features of ADEM, but nonspecific. Therefore, clinical correlation is required in evaluating ADEM.
