2.Perinatal Hypoxic-lschemic Brain Injury: MR Findings.
Journal of the Korean Radiological Society 1994;31(3):405-410
PURPOSE: To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. MATERIALS AND METHODS: SE T1 -, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions RESULTS: MRI demonstrated the followings;(1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. CONCLUSION: MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult.

PURPOSE: To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. MATERIALS AND METHODS: Fifty-two(95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. RESULTS: The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm3, respectively. There was a significant sex difference in the sinus volume(p<0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides(p<0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume(p<0.0001). CONCLUSION: In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

8.Reliability of spiral tomography for implant site measurement of the mandible.
Journal of Korean Academy of Oral and Maxillofacial Radiology 1997;27(2):27-48
The purpose of this study was to evaluate the accuracy and usefulness of spiral tomography through the comparison and analysis of SCANORA cross-sectional tomographs and DentaScan computed tomographic images of dry mandibles taken by a SCANORA spiral tomographic machine and a computed tomographic machine. Thirty-one dry mandibles with full or partial edentulous areas were used. To evaluate the possible effect of location in the edentulous area, it was divided into 4 regions of Me (region of mental foramen), M1 (the midportion between Me and M2), M2 (the midportion between mental foramen and mandibular foramen) and S (the midportion of the mandibular symphysis). A ZPC column (sized 4 mm X 5 mm) was seated on the edentulous regions of Me, M1, M2 and S using the acrylic stent. Then SCANORA spiral tomography and computed tomography were taken on the edentulous regions which contained the ZPC column. The ZPC columns and cross-sectional images of the mandible were measured in the radiographs by three observers and the differences between the two imaging modalities were analysed. The results were as follows: 1. In comparing the actual measurements of the ZPC column and measurements in the radiographs, the mean error of the DentaScan computed tomography was 0.07 mm in vertical direction and -0.06 mm in horizontal direction, while the mean error of the SCANORA spiral tomography was 0.06 mm in vertical direction and -0.12 mm in horizontal direction. There was a significant difference between the two radiographic techniques in the horizontal measurement of the ZPC column of the symphysis region (p<0.05). but there was no significant difference in the measurements of other regions>0.05). 2. In measurements of the distance from the alveolar crest to the inferior border of the mandible (H), and of the distance from the alveolar crest to the superior border of the mandibular canal (Y), there was no significant difference between the two radiographic techniques (p>0.05). 3. In measurements of the distance from the lingual border of the mandible to the buccal border of the mandible (W), and of the distance from the lingual border of the mandible to the lingual border of the mandibular canal (X), there was a significant difference between the two radiographic techniques in measurements of the midportion between the mental foramen and the mandibular foramen (M2) (p<0.05). but there were no significant differences in measurements of the other regions of symphysis>0.05). 4. Considering the mean range of measurements between observers, the measurements of SCANORA spiral tomography showed higher value than those of DentaScan computed tomography, except in measurements of symphysis (S). 5. On the detectability of the mandibular canal, there was no significant difference between the two radiographic techniques (p>0.05). In conclusion, SCANORA spiral tomography demonstrated a higher interobserver variance than that of DentaScan computed tomography for implant site measurements in the posterior edentulous area of the mandible. These differences were mainly the result of difficulty in the detection of the border of the mandible in SCANORA spiral tomography. But considering the cost and the radiation exposure, SCANORA spiral tomography can be said to be relatively good radiographic technique for implant site measurement.

9.Persistent Mullerian Duct Syndrome in a Boy with Transverse Testicular Ectopia: a Case Report.
Korean Journal of Urology 1998;39(11):1158-1160
Persistent mullerian duct syndrome is characterized by the presence of mullerian structures in male subiects with normal penile and scrotal development. A deficiency of activity of a mullerian inhibiting substance during gestation is believed to be responsible for this syndrome. To date approximately 150 cases of persistent mullerian duct syndrome have been reported and the syndrome of transverse testicular ectopia with persistent mullerian duct structures is much rarer. In Korea, this is the fourth case to be reported. We report a case of persistent mullerian duct syndrome with transverse testicular ectopia in a 7 month-old-boy. Both testes were in the right side of scrotum but no epididymises were found there, which resulted in the disruption of normal relationship between the was and testis. Regarding there was no fertility, mullerian duct structures were removed.

Tibric acid is a new oral hypolipidemic agent with the chemical name of 2-chloro-5(3,5-dimethyl piperidinosulfonyl) benzoic acid. The results of tibric acid administration in 22 patients with primary hyperlipidemia were as follows. 1) Serum triglyceride level was significantly decreased in 84.6% of 22 cases with an average 43.9% decrease in serum triglyceride. 2) Serum cholesterol level was decreased in 59.1% of 22 cases with an average 15.8% decrease in serum cholesterol. The decrease in serum cholesterol level was not significant. 3) It seemed that there were significant falls in the serum triglyceride of the hyperlipoproteinemia type IV and IIb patietns and in the serum cholesterol of type IIa patients 4) The side effects of tibric acid were indigestion, loose stool and anorexia. There was no side effects in 63.6% of cases.
