CT is a highly accurate method of detecting and clarifying the narure of space-occupying lesions within theliver nd pancreatic disease. It was found to be a reliable, non invasive method for detecting the lesion. A normalrange of attenuation values were obtained from 71 CT examinations of the upper abdomen, that is liver, spleen,pancreas, aorta, before and after contrast enhancement in whom no radiologic or laboratory abnormality of theseorgans were detected from March to Sept. 1983. The results were as follows; 1. The age distribution was from 28years to 71 years. The sex ratio was 45 male to 26 female. 2. Mean Hounsfield Units (HU) in liver before contrastenhancement and after contrast enhancement liminute, 3 minutes, 5 minutes, 10 minutes were 56.1±3.85, 75.0±4.77,82.0±3.71, 84.3±2.76 and 88.2±3.95 HU respectively. 3. Mean Hounsfield Units in pancreas before contrastenhancement and after contrast enhancement 1 minute, 3 minutes, 5 minutes, 10 minutes were 43.0±4.30, 66.5±4.27,71.2±2.39, 74.4±3.00 and 79.2±2.(0 HU respectively. 4. Mean Hounsfield Units in spleen before contrastenhancement and after contrast enhancement 1 minute, 3 minutes, 5 minutes 10 minutes were 53.0±4.31, 71.4±2.84,75.3±2.70, 80.5±3.04 and 83.2±2.14 HU respectively. 5. Mean Housfield Units in aorta before contrastenhancement and after contrast enhancement 1 minute, 3 minutes, 5 minutes 10 minutes were 45.1±5.39, 86.7±6.86,92.5±5.33, 106.8±4.12 and 114.1±5.02 HU respectively. 6. The most significant finding was that the livernormaly had the highest attenuation values of any of the organs measured. When another viscera in upper abdomenhad a attenuation value greater than that of the liver, this reflected abnormal lesions.

PURPOSE: To evaluate the usefulness of CT for the diagnosis and treatment planning of mechanical intestinal obstruction. MATERIALS AND METHODS: We retrospectively reviewed 38 patients who were clinically suspected of mechanical intestinal obstruction and had undergone abdominal CT. The CT scans were evaluated for the absence or presence, severity, cause and site of intestinal obstruction. CT findings were compared with the results of laparotomy, barium study and clinical course. The absence or presence and severity of intestinal obstruction were classified into no obstruction, partial obstruction, complete obstruction. Diagnosis was estabilished by means of laparotomy in 20 cases, barium study in 9 cases and clinical course in 9 cases. RESULTS: Of 38 cases, 7(18.4%) showed no obstruction, 22(57.9%) showed partial obstruction, and 9(23.7%) showed complete obstruction. The presence or absence and severity on CT scans were corretly predicted in 36 of 38 cases (sensitivity 95%, specificity 97%, accuracy 96%) (in case of no obstruction:sensitivity 100%, specificity 94%, accuracy 95%;in case of partial obstruction:sensitivity 91%, specificity 100%, accuracy 95%;in case of complete obstruction:sensitivity 100%, specificity 100%, accuracy 100%). All 9 cases with complete obstruction underwent prompt and immediate laparotomy. 13 cases, excluding those with mass around the site of transition and adhesion with strangulation, with partial obstruction improved with conservative treatment without laparotomy. The causes of obstruction were adhesion in 13, hernia in 6, primary cancer in 5, metastatic cancer in 3, abscess in 2, intestinal tbc in 1, and Crohn's disease in 1. The cause of obstruction on CT scans were correctly predicted in 27 of 31 cases (87.1%). The sites of obstruction on CT scans were correctly predicted in 22 of 26 cases (84.6%). CONCLUSION: CT is valuable in the evaluation of absence or presence, severity, cause and site of intestinal obstruction, and is considered to be helpful in treatment planning for the patients with intestinal obstruction.

Neoplasms of the nasophrynx are rare in neonates and infants. The most common nasopharyngeal tumor encountered in this age group is teratoma-neoplasm containing multiple heterotopic tissues. Four histologic types of nasopharyngeal teratoma occur-dermoid, teratoid, true teratoma, epignathiof which dermoid is most frequently seen. We have experienced a case of nasopharyngeal teratoma in a female neonate with signs and symptoms of upper airway obstruction. It was diagnosed by cervical. CT and confirmed as ture teratoma by histological examination. Nesopharyngeal teratoma was removed by contact Nd:YAG laser. In addition, we briefly reviewed the literature of neonatal nasopharyngeal teratoma.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

The goal of fracture treatment is to restore the patient to pre-injury function level. But the outcome assessment after orthopedic interventions has usually focused on physician-defined parameters of technical success, such as fracture union, alignment and range of motion rather than patient function and quality of life. However, the correlation among improvements in these parameters and functional status, psychosocial well being is inconsistent and weak in the elderly. Therefore authors assessed the functional status after surgical intervention of hip fractures in the elderly with functional recovery score(FRS). Independence in basic activities of daily living, in instrumental activities of daily living, in mobility, freedom from pain and intact memory were assessed in 133 hip fractures in the elderly. The hip fractures in the elderly resulted in 24.8% loss of function after the first year. The older the age, the more the loss of function after surgery of hip fractures. The more functional loss was observed in female patients and in patients with poor postoperative radiological results, but statistically insignificant (P>0.05). The more functional loss was observed in patients with underlying medical disease preoperatively and it was statistically significant (P<0.05). We recommend the evaluation of functional status in the elderly after hip fractures.

Mucocuaneous Lymph Node Syndrome(Kawasaki disease) is a new diseae entity that was first described by Kawasakiin 1967. It occures predominantly in children less than 5yrs old and acute febrile illness, which is mucocutaneousinvolvment associated with swelling of cervical lymph nodes. The coronary artery aneurysms have been revealed 20–30% of patients with Kawsaki disease. The authors report a case of multiple coronary artery aneurysms inKawasaki disease which was diagnosed by a coronary arteriography.

The purpose of this study was to quantify the amount of remaining gutta-percha/sealer on the walls of root canals when three types of nickel-titanium rotary instruments(Profile, ProTaper and K3) and a hand instrument(Hedstrom file) used to remove these materials. The results of this study were as follows: 1. In the total time for gutta-percha removal, Profile group was the fastest and followed by K3, Protaper, Hedstrom file group. 2. In case of the evaluation of the volume of remained gutta-percha from radiograph, K3 group got the highest score and followed by Protaper, Hedstrom file, Profile group in the apical 1/3. 3. In case of the evaluation of the volume of gutta-percha remained from stereomicroscope, K3 group got the highest score and followed by Protaper, Hedstrom file, Profile group in the apical 1/3. These results showed that instrumentation using nickel-titanium rotary instrument groups was faster than that using hand instrument group. The effect of gutta-percha removal using Profile group was better than that using Protaper and K3 group in the nickel-titanium rotary instrument groups.
