Evidence in human studies of the association of long term habitual exercise with bone mineral content (BMC) and bone mineral density (BMD) mostly come from studies done on athletes. The highest BMC and BMD values in young adults have been found in strength and power-training athletes, while endurance activities such as long distance running and swimming seem to be less effective in obtaining peak bone mineral density. To compare the differences in BMD among ballet, Korean traditional dancing and athletics, we examined the BMD of 10 ballerinas, 10 Korean traditional dancers, 12 athletes and 12 volunteers as the control group. All participants were female. The average age were 20.6 years for the ballerinas, 21.2 for the Korean traditional dancers, 20.4 for the athletes and 21.3 for the control group. Average weights were 50.6 kg for the ballerina, 53.7 kg for the Korean traditional dancer, 59.2 kg for the athletes and 53.8 kg for the control group. Average heights were 162.0 cm for the ballerinas, 160.4 cm for the Korean traditional dancers, 162.3 cm for the athletes and 160.5 cm for the control group. There were no significant differences in the BMD values of the proximal femur and the lumbar spine between ballerinas and control group and between Korean traditional dancers and control group (p>0.05). There was, however, a significant increase of BMD in the proximal femur and lumbar spine of the athletes when compared with the control group (p<0.05) After adjusting for difference in body mass index (BMI) we recompared the BMD of ballerinas, Korean traditional dancer and athletes with BMD of control group and found significant higher lumbar spine BMD values in ballerinas, Korean traditional dancers and athletes. In athletes higher BMD levels were also obtained in the proximal femur including the neck, greater trochanter and Wards triangle regions (p<0.05). There was no significant increase of proximal femur BMD levels for Korean traditional dancers (p>0.05). Differences of BMD values between the ballerinas and control group was statistically significant only in femoral neck (p<0.05).

Leri-Weill syndrome or Leri-Weill dyschondrosteosis represents a short stature syndrome that is characterized by symmetric shortening of the forearms and lower legs and a bilateral shortening and bowing of the radius with a dorsal subluxation of the distal ulna(Madelung deformity). Recent genetic analyses demonstrated that functional haploinsufficiency of SHOX(short stature homeobox-containing gene) accounts for Leri-Weill syndrome. Further studies are needed to explain phenotypic heterogeneity of SHOX defect. We experienced a case of Leri-Weill syndrome in a 11-year-old girl with short stature, who revealed typical Madelung deformity, mesomelic(middle segment) dysplasia, and a karyotype of 46,XX. In cases with dyschondrosteosis or Turner-characteristic dysmorphic skeletal features, detection of SHOX mutation is recommended.

Roentgenograms of the chest were reviewed from 122 childrens with acute glomeruloneph ritis. Abnormalities were found in 110 roentgenograms. These included cardiomegaly in 82(67.2%), prominent pulmonary vasculature in 98(80.3%), pleural effusion in 35(28.6%), pulmonary edema in 24(19.6%), and pulmonary consolidation in 20(16.3%). The roentgen findings in the chest, although not pathognomic, may have diagnostic values occasionally.

Paragonimiasis is widely distributed in Far East and Southeast Asia, particularly in Korea. The centralnervous system is the most frequent location for paragonimiasis outside the lungs. We analized the computedtomographic findings of 17 cases which were diagnosed pathologically and clinically as cerebral paragonimiasis.The results were as follows; 1. The ratio of male to female was 10:7 and about 88% of cases were under the age of40 years. 2. The common location so cerebral paragonimiasis were the occipital (12 cases ) and temporal (11 cases) lobes. 3. Precontrast CT findings of cerebral paragonimiasis were low density with calcifications in 6 cases,low and isodensities in 4 cases, mixed densities in 3 cases, only low density in 2 cases and only calcification sin 2 cases. Hydrocephalus (7 cases), mass effect (6 cases), atrophic change(6 cases) and cyst formation (3 cases)were associated. 4. The shape of calcifications in CT scan were soap-bubble or ring in 6 cases, nodular or oval in6 cases, stippled in 4 cases and amorphous conglomerated in 2 cases. 5. The contrast-enhanced 8 cases were 5 ringor rim like, 2 nodular and 1 irregular enhancements, while 9 cases were not enhanced.

INTRODUCTION: There are three anatomic findings that correlate with a patient risk for developing anterior acromial impingement : acromial shape, anterior downsloping of the acromion. To analyze the effect of anterior and lateral downslopings and subacromial interval to the impingement syndrome retrospectively, the authors reviewed 32 patients who performed MRI of the shoulder joint in the Dankook university hoipital. MATERIALS AND METHODS: Eighteen males & fourteen females were reviewed and the average age was 46.6 years old. There were 23 cases of impingement syndrome and 9 cases of control group. The authors analyzed oblique coronal images and oblique sagittal images in shoulder MRI.
