The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

Membranous obstruction of the hepatic inferior vena cava(MOVC)is one of the common causes of Budd-Chiari syndrome. The aim of this study is to ascertain and compare the characteristic sonographic and CT findings of Budd-Chiari syndrome caused by MOVC. We studied 10 patients of Budd-Chiari syndrome caused by MOVC through sonography and CT. MOVC was confirmed by operation and/or inferior vena cavography. The cases included 9 men and one woman. With sonography. IVC obstruction was diagnosed in 9 cases. The cause of IVC obstruction was web in 5 cases and fibrous cord in 3 cases. The cause was unspecified in on case. Obliteration of the hepatic veins and intrahepatic collateral vessels were delineated in 9 cases. With color doppler sonography, the directions of blood flow of the hepatic veins through the intervenous communication were fairly well demonstrated in all 5 cases. With CT, IVC obstruction was diagnosed in 7 cases. The obliteration of the hepatic segment of the IVC were segmental in 6 cases and diffuse in one case. Ct demonstrated communicating vessels between the hepatic veins in 3 cases. Furthermore. Systemic collateral vessls(azygos and hemiazygos veins. Veins along the abdominal wall, and internal mammary veins)were demonstrated in all cases. Liver cirrhosis was combined in all cases and hepatoma developed in 4 cases. Sonography is useful to detect the MOVC and to demonstrate hepatic venous obstruction and intrahepatic collateral vessels. Color doppler sonography is easily performed to show the direction of the blood flow through interconnecting vessels. CT shows the obliterated segment of the IVC clearly and multiple prominent systemic coliaterals. In conclusion, and Budd-Chiai syndrome caused by MOVC is accurately diagnosed by combined color doppler sonography and CT.

The present study was carried out to clarify the anatomical changes of lumbar intervertebral discs by aging. Anterior height, posterior height, anteroposterior diameter of intervertebral discs were measured on 512 normal plain lateral radiographs of lumbosacral spine. And the indices of disc wedging and relative disc height were calculated. There was a cephalocaudal gradient of increase in the indices of disc wedging in all age groups. The indices of relative disc height were constant at all lumbar levels. These suggest that the lower disc is more wedge shaped and the height of discs changes in the constant ratio with that of vertebral body.

The findings of upper gastrointestinal series(UGI), computed tomography (CT), and sonography(US) of ten duodenal adenocarcinoma confirmed by surgery (n=7) and endoscopic biopsy (n=3) were retrospectively analyzed. We performed US in all cases, CT and UGI in 8 out of 10 cases. UGI showed 4 cases of ulcerating type, 3 of stenotic type, and one failed to visualize duodenum due to previous gastrojejunostomy. UGI was more accurate in depicting the mucosal changes such as ulcer, however, it played a limited role in the evaluation of extraluminal extension. US showed 4 cases of hypocchoic wall thickening, 3 of hypoechoic extraluminal mass, and one of polypoid intraluminal mass but 2 were not detected on US. US accurately detected hepatic and pancreatic metastasis, however, it played a limited role in the evaluation of direct colonic invasion. CT showed was eccentric wall thickening in 4 cases, large extraluminal mass in 2, and low density intraluminal mass in but one was missed on CT. CT was the most accurate modality to determine the extent of the lesion and adjacent or distant metastasis but it could be misdiagnosed as submucosal tumor if the extraluminal component is large. UGI, CT and US can be used complementary for accurate diagnosis of a duodenal cancer. US may be used as a screening tool for detecting duodenal cancer.

PURPOSE: Authors retrospectively evaluated the efficacy of superselective renal arterial emboliation in 5 patients with symptomatic renal angiomyolipoma. MATERIALS AND METHODS: Five Patients with renal angiomyolipoma who had been treated with superselective renal arterial embolization were analysed retrospectively. Two patients who had multiple bilateral lesions were associated with tuberous sclerosis. The mbolic materials used were absolute alcohol in 6 sessions, absolute alcohol mixed with lipiodol in one session, and polyvinyl alcohol in one session. RESULTS: We could observe devascularization of the tumor on the post-embolization arteriograms. The symptoms such as flank pain were improved in all patients during the follow-up period of 3 months to 3years. CONCLUSION: Superselective renal arterial embolization is an effective and safe procedure in the management of renal angiomyolipomas.

PURPOSE: The admission rates for pediatric asthma are increasing annually and are partially responsible for the increased rates of readmission. Selections of children with a high-risk of readmission and aggressive treatments of them may improve treatment outcome and cost- effectiveness. The purpose of this study is to evaluate the risk factors affecting readmission in cases of bronchial asthma in children. METHODS: We reviewed the medical records of 95 cases under 14 years of age who were admitted to the Department of Pediatrics, Kyung-Hee University, from March 1996 to February 1997 and divided them into readmission and first admission group. RESULTS: Readmission cases were 52 (55%). Age, sex, duration of admission, duration of oxygen therapy, serum IgE concentration, duration of symptoms prior to admission and severity of asthma were not statistically significant compared with those of the control group (t-test) (P>0.05). Use of prophylactic agents, family history of allergic diseases and past history of bronchiolitis were significant (P<0.05), but age under 4 years and sex were not significant (X2-test). Age under 4 years, history of bronchiolitis, and history of previous hospital admission for asthma were significant (P<0.05), but sex, severity of asthma, history of frequent upper respiratory tract infection, family history, and the use of prophylactic agents were not statistically significant (P>0.05) as independent risk factors. CONCLUSION: Age under 4 years, past history of bronchiolitis, and history of previous hospital admission for asthma were significant risk factors for hospital readmission. Further study needs to be done to decrease the readmission rates.

Journal of the Korean Radiological Society 1992;28(4):601-608
Each Disease affecting the bile ducts tends to produce characteristic pattern of billiary dilatation: recurrent pyogenic cholangitis causes dilatation and straightening of the larger(central) intrahepatic ducts ; clonorchiasis causes dilatation of the smaller (peripheral) intraahepatic ducts; and carcinoma along the extrahepatic ducts causes (proportional) dilatation and tortuosity of both larger and smaller intrahepatic ducts. To evaluate the specificity of the pattern and morphology of the dilated biliary tree on CT scancs (CT characterization) three independent radiologists who were unfamiliar with the cases were asked to classify 62 CT scans in patients with obstructive jaundice. The case population consisted of 14 cases with recurrent pyogenic cholangitis, 18 cases with clonorchiasis and 30 cases with carcinoma along the extrahepatic ducts, which were intermixed randomly. Classification was made only on the basis of CT characterization: those scans showing primary lesions i.t., stone, aggregate of flukes, or tumor mass were excluded or masked. All the scans of every case showing the extrahepatic bile duct were masked. Radiologists correctly classified 54 of the 62 cases (87%): ten of the 14 patients with recurrent pyogenic cholangitis(71%), 17 of the 18 patients with clonorchiasis(94%) and 27 of the 30 patients with carcinoma along the extrahepatic bile cucts(90%). We believe that CT characterization of bile duct dilatation is useful in the differential diagnosis of obstructive jaundice, especially when a primary pathologic lesion is not depicted in CT scans.

Our purpose is to describe a successful twin pregnancy and delivery after intracytoplasmic sperm injection (ICSI) followed by calcium ionophore with spermatozoa from a globozoospermic man. On the second attempt of ICSI, all of eight metaphase II oocytes were fertilized with treatment with calcium ionophore. Day 3 transfer of six normally developing embryos resulted in an ongoing twin pregnancy, and two preterm healthy babies were born in the 33th week of gestation. To the best of our knowledge, this is the first report of pregnancy and delivery after ICSI followed by calcium ionophore with spermatozoa from a globozoospermic man in Korea.
