Utrerine myoma is one of the most commonly encountered gynecologic problem in daily ultrasonographic practice,and is one of the few conditions with which specific histologic diagnosis is possible by ultrasonography in selected patients as well. We recently analysed ultrasonograms of 132 cases of uterine myoma and 31 cases thatshowed similar ultrasonographic findings of myoma, histopathologically verified in both cases. The results were as follows. 1. The diagnostic accuracy by ultrasonography was 93%. 2. The most common ultrasonographic findings of uterine myoma were nodular enlargement of uterus and irregular internal echo texture changes. 3. It was not possible to differentiate the various kinds of secondary degeneration by ultrasonography, except for calcification and cystic change. 4. It was usually unable to differentiate solitary from multiple myoma, and subserosal,interstitial and submucosal types from each other by ultrasonographic findings alone, except for the usual cases of exophytically growing subserosal mass. 5. The most frequent disease that is hard to differentiate from small uterine myoma was adenomyosis, and therefore it is considered necessary to include the adenomyosis in differential diagnosis in the diagnosis of myoma causing moderatelly enlarged uterus.

The osteonectin is a sort of glycoprotein which is secreted in human tissues. The osteonectin is generally detected in number of normal or neoplastic human tissues in vivo, but hasn`t been studied the role of osteonectin in developing human teeth and odontogenic tumors. We evaluated degree of the expression of osteonectin immunohistochemically in 20 cases of developing tooth germ which growth from fetus 5 to 38 weeks, and total 51 odontogenic tumors whitch has taken from routine biopsy, such as 10 ameloblastomas, 5 cases of adenomatoid odontogenic tumors and odontomas and odontogenic fibromas, 4 cases of cementomas and calcifying epithelial odontogenic cyst and odontogenic keratocyst and dentigerous cysts and periapical cysts, and 3 cases of ameloblastic fibromas and myxomas. The results were as follows: 1. The osteonectin on the bud stage of tooth germ was strongly expressed in the epithelial dental lamina and in the outer dental epithelium on the early bell stage, and also strongly expressed in the inner dental epithelium on the late bell stage of tooth germs. 2. In ameloblastoma, the osteonectin was strongly expressed in the epithelial tumor component and especially in the acanthomatous types. 3. In both of calcifying epithelial odontogenic tumor and adenomatoid odontogenic tumors, the osteonectin was moderately expressed on the duct like spindle cells and epithelial tumor cells around calcification areas. 4. In odontogenic tumors originated from epithelial-mesenchymal tissues, the osteonectin was moderately expressed on the epithelial tumor components and in odontogenic cysts, it was expressed in ghost cells and calcification areas only. These were summaried the osteonectin may be strongly related to the developing tooth germ and odontogenic tumors and could be regulated hard tissue of human tooth in morphogenesis and involved with calcification mechanism in development odontogenic tumors.

CT is the most accurate and reliable method for the diagnosis of intracerebral and intraventricularhemorrhage. The precise anatomic extent of the hematoma, associated cerebral edema, ventricular deformity anddisplacement, and hydrocephalus are all readily assessed. Aside from head trauma, the principal cause ofintracerbral hematoma is hypertensive vascular disease. Although hematomas from various causes may present similarCT appearances frequetnly the correct etiology may be suggested by considereation of patient's age, clinicalhistory, and the location of the hematoma. The analytical study was performed in 180 cases of intracerebralhamorrhages by CT from Oct. 1981 to Jan. 1983. The results were as follows; 1. The most prevalent age group was6th decade(37.2%) Male was prevalent to female at the ration of 1.6 to 1. 2. The most common symptom and sign wasmental distrubance (48.7%), motor weakness(23%), headache(10.6%), nausea and vomiting (9.8%). 3. The causes ofhemorrhage were hypertension (53.9%), head trauma (30.6%), aneurysm(6.1%) and A-V malformation (7.2%). 4. Thefrequent locations of hemorrhage were basal ganglia and thalamus(40.4%), lobes(35%), ventricles(21.8%). 5. Thedistribution of hemorrhage was intracerebral hemorrhage(65.6%), intracerebral and intraventricularhemorrhage(30.3%), intraventricular hemorrhage(4.4%).

Obstruction of the inferior vena cava(IVC) is an uncommon condition, and the collateral pathway variesaccording to the level, extent, duration and the cause of obstruction. Membranous obstruction of IVC in itshepatic portion might be one of the principal cause among Korean, though not reported till now. Analytical studywas perfomred in 26 cases of IVC obstruction with various cause. 1. The level of the obstruction showed relativelyeven distribution as follows, upper caval in 11 cases, middle caval in 6 cases and infrarenal in 9 cases. 2. Themain cause of upper caval obstruction was membranous obstruction . 3. As a whole, the main collateral pathway wasthe central route(22 case:85%). 4. Characteristic collateral pathway unique to upper caval obstruction wastranshepatic vanous collateral, developed between the obstructed segment and unobstructed segment of IVC. 5.Scalloping of left cardiac border produced by pericardiophrenic venous collateral was characteristic simple chestX-ray finding in IVC obstruction.

We had treated 24 patients who had nonunions of the carpal scaphoid from June 1987 to September 1995. 17 of 24 nonunions of carpal scaphoid were treated by K-wires fixation and autogenous iliac bone grafts. Another 7 cases were treated by Herbert screw fixation and autogenous iliac bone graft. 24 patients were followed up average 42.6 months and obtained following results; l. Among 24 cases, 23 cases were men and 19 cases were the third and fourth decade. Most common injury was the falling accidents (11 cases: 45.8%). 2. Most common pattern of fractures was waist type (20cases: 83.3%) in anatomical site and transverse type (15 cases: 75.0%) in pattern of fracture line. 3. Preoperative scapholunate angles (mean 52.9degrees: K-wires, 69.1degrees: Herbert screw) has been improved after open reduction and internal fixation by K-wires or Herbert screw (mean 46.2degrees: K-wires, 51.1degrees: Herbert screw). 6 cases had DISI deformity preoperatively with scapholunate angles over 70degrees (mean 80.0degrees: K-wires, 84.0degrees: Herbert screw) has been corrected after ORIF (mean 48.0: K-wires, 58.0: Herbert screw). 4. Bony unions were obtained in average 13.2 weeks in K-wires group and 9.8 weeks in Herbert screw group. 5. 13 cases (76.5%) in K-wires group and 6 cases (85.7%) in Herbert screw group were excellent and good result by Maudsley method. 6. The complications and sequalaes were present 4 cases in K-wires group with degenerative arthritis on radioscaphoidal and scapholunate joint and collapse of proximal pole and 1 case in Herbert screw group with screw malposition. So, We were thought that ORIF with K-wires and Herbert screw was effective treatment for nonunions of carpal scaphoid, especially Herbert screw fixation and autogenous iliac bone graft. In comparison of bony union and results of treatment, Herbert screw group was more effective than K- wires group.

Myocardial bridging is defined as segmental engulfment of a major epicardial coronary artery by myocardial fibers, causing a systolic narrowing or milking effect of the coronary arterial segment. During systole, the intramuscular part of coronary artery is compressed by contraction of overbridging ventricular muscle, therefore blood flow distal to the lesion is impaired and angina pectoris or acute myocardial infarction may occur. We experienced a case of Non-Q myocardial infarction in a 42 years-old female patient with myocardial bridge at the proximal and middle part of left anterior descending coronary artery.

Gelastic Seizure(Ictal laughter) is frequently associated with hypothalamic hamartoma that is congenital tumor composed of heterotrophic and hyperplastic tissue located in the hypothalamus near the interpeduncular cistern, tuber cinereum, and mamillary body. The seizure usually begins in infancy or childhood and may be accompanied with precocious puberty and cognitive decline. A 14 year-old boy visited to our hospital because of paroxysmal frequent involuntary laughing regardless of emotional change. Brain MRI showed nonenhancing hypothalamic mass that had isointensity with gray matter on T1W1 and hyperintensity on T2Wl. So it was suspected that he had a gelastic seizure accompanied with hypothalamic hamartoma.

The ptosis secondary to cerebral hemispheric lesion (cerebral ptosis) is unusual and has not been well documented. Although the precise anatomical localization and clinical course of cerebral ptosis were not clear, there have been a few clinical and electrophysiologlcal reports that right hemisphere had its functional asymmetry or dominancy in the cortical control of eyelid movement. We present 4 patients of cerebral ptosis with acute onset of cerebral infarction in right middle cerebral artery territory. All of them are right-handed and presented acute onset of left hemiparesis and bilateral ptosis, but have no signs of involvement of oculomotor or sympathetic nerve pathway. In conclusion, the blepharoptosis could be caused by hemispheric lesion per se and be a sign of right hemispheric lesion rather than that of left one.

In 31 cases of abdominal vascular lesions including aorta, inferior vena cava and portal vein, ultrasonographyand angiography were done at departement of radiology, Seoul National University Hospital, for recent 3 years forcomparative analysis of those findings. The results are ad follows: 1. There are 11 cases of abdominal aorticlesion such as atherosclerotic aneurysms and dissecting aneurysms, 12 cases of inferior vena cava lesion such asmembraneous obstruction and 5 cases of portal vein invasion due to hepatoma. 2. Ultrasonography revealed enlargedlumen and extent of the lesions in all cases of aortic aneurysm and showed intraluminal thrombus more accuratelythan aortography. 3. Intimal flap was detected in all case of dissecting aneurysm, however, ultrasonography couldnot show proximal extent and involvement of major branches. 4. In the cases of inferior vena cava obstructionultrasonography revealed obstruction site and extent of the leisons accurately but vena cavography depictedcollateral circulation better. 5. In 5 cases of angiographic portal vein invasion due to hepatoma, portal veinthrombus was detected in 4 cases by ultrasonography. And ultrasonography could not reveal collaterals,arteriovenous shunt and thread and streaks sign.

We have studied thirty two cases of inappropriately treatable and intractable epileptics to various anti-convulsants. Zonisamide had a definite anti-epileptic activity in eleven subjects(52.4%) of intractble epilepsy. Five patients(45.5%), who were previously inappropriately treatable epileptic patients became seizure free on zonisamide. Two subjects were withdrawn from study because of side effect and two subjects were also withdrawn because of uncontrolled seizure. Zonisamide is not only effective in intractable epileptic patients but also in first trial for untreated epileptic patients.
