A 23 year-old female with skeleto-dentoalveolar protrusion of maxilla, minor broken contact points between anterior teeth, and missing of lower 1st molars, has been treated with multibanded edgewise technique. After treatment of 14 months, she has gained functional overbite-overjet relationship and facial harmony due to the retraction of upper anterior teeth. Root resorption was slight. Especially, us ing the space of missed lower 1st molars instead of extracting lower premolars, expected and favorable results were obtained.

Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

We report a case of nonsyphilitic isolated coronary ostial stenosis of the left main coronary artery observed by transesophageal echocardiography(TEE) in a 52-year-old woman with angina. The lesion was suspected during coronary angiography and it was not visualized by transthoracic echocradiography. Coronary ostial stenosis, which is potentially lethal as left main coronary artery disease, occurs rarely in the absence of other coronary artery disease. The diagnosis of ostial stenosis has been usually made by the use of coronary angiography, however, it may be difficult to diagnose at angiography if angiographic catheter is positioned across the stenotic lesion, and the unexpected serious complication during coronary angiography in such a patient may happen. The new ultrasonic imaging technique of TEE provides more detailed images of proximal coronary anatomy and coronary blood flow.

In the diagnosis of bile duct carcinoma, oral or intravenous cholangiography is of no air in the majority ofpatients with bile duct carcinoma who are jaundiced. Recently ultrasonography and CT are widely used for evalutionof biliary disease, but direct visualizing methods of the biliary tract by ERCP and PTC gives more detailed information and exact localization of the lesion. ERCP is less invasive and dangerous and has some more advantages than PTC. We analyzed 33 cases of confirmed extrahepatic bile duct caracinoma who were performed ERCP. The resultswere as follows; 1. The 7th decade was the predilection age, and the radio of male to female was 3.:1. 2. Thelocations of extrahepatic bile duct carcinomas were common bile duct in 45.5%, common hepatic duct in 27.3%,junction of cystic duct and widely extended in 12.1% respectively and junction of hepatic duct in 3.05 in order offrequency. 3. ERCP finding of extrahepatic bile duct carcinomas revealed complete obstruction of bile duct in mostcases, and irregular margined protuberant type was more common than smooth margined constricted type atobstruction site. 4. ERCP finding according to the location of lesion showed that protuberant type was relativelyfrequent in common bile duct and constircted type in common hepatic duct respectively.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

Twenty-six cases of fracture of the femur and tibia on the same leg were treated in Masan Koryo General Hospital during the period 1981 1986. We studied all of these patients, divided by four groups according to the method of treatment, retrospectively with analysis of treatment and end results. The results were as follows : 1. Twenty-two patients were male and four patients were female. Of twenty-six patients, eighteen patients were at their third and fourth decades. 2. The main cause of injuries was traffic accident; 23 patients(88%). 3. The most common concomitant injury was fracture and dislocation in other site(14 cases). The fat embolism developed in one case and one patient had died due to head injury. 4. The average healing time of fracture was 17 weeks in femur and 20 weeks in tibia in group three, that was most rapid of all groups. 5. A good or excellent functional result was achieved in 87% of the patients treated with internal fixation of both fracture, 75% of the patients with internal fixstion for the femur fracture and external fixation for the tibial fracture, and 25% of the patients trested conservatively.

Epilepsy can be divided into idiopathic epilepsy and symptomatic epilepsy according to the existence ofunderlying organic disease. It has been said that the incidence of the symptomatic epilepsy caused by underlyingorgainic brain disease is higher in late-onset epilepsy after the age of 20 than in childhood-onset epoilepsy. CTis very sensitive and non-invasive method for detection of organic brain disease. 168 cases of late-onset epilepsyafter the age of 20 were studied by CT in recent 2 years were analyzed. The results were as follows; 1. The 3rddecade was the most frequent age group, and the ratio of male to female was 2.5;1. 2. Structural abnormality onbrain CT was demonstrated in 51.8% of hte patient. 3. The older the onset of age was, the higher the rate of theabnormal CT finding, except 5th decade which showed less CT abnormality than 4th decade. 4. The most frequenthistory related to epilepsy was trauma. 63.1% of the patients had no relevant history; and they showed CT findingsof brain tumor, atrophy and infarction in decreasing order of frequency. 5. Abnormal CT finding was demonstratedin 49.2% of normal neurologic examination and in 46.4% of normal EEG study. 6. The most frequent lesion ofabnormal CT scan in late-onset epilepsy was 30 cases(18.4% )of brain atrophy. The next frequent lesion was 18cases (10.7%) of brain tumor. Infarction, parasites and calcification were other frequnet lesions.
