Isolated situs in versus of the stomach with otherwise normal position of the thoracic and abdominal vescera isan extremely rare anomaly occurring in two distinct forms. Majority of cases are associated with eventration of the diaphragm and are reported as being confused with spontaneous pneumothorax of pyopneumothorax at base of the right lung. The right sided stomach may produce interesting and confusing changes in liver scan. We have experienced 2 cases of the isolated dextrogastria.

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%).

Induction of general anesthesia with direct laryngoscopy and tracheal intubation is routine procedure but causes varying degree of sympathetic stimulation such as increasing in blood pressure and heart rate. Many approaches have been tried to attenuate these hemodynamic responses. To evaluate the effects of nicardipine, a new calcium channel blocker, for prevent sympathetic stimulation induced by direct laryngoscopy and tracheal intubation, we administered nicardipine (40 mg P.O.) 60 minutes before laryngoscopy and endotracheal intubation. 60 patients, ASA physical status 1,2, scheduled operation, were selected randomly. We divided these patients into two groups. Group 1: control, valium 0.1-0.2 mg/kg P.O. (N=30), Group 2: valium 0.1-0.2 mg/kg with nicardipine 40 mg P.O. (N=30). We measured systolic blood pressure, diastolic blood pressure and heart rate before premedicstion, before induction and 1,3,5,10 minutes after intubation in both groups and compared with control group. The results were follows ; 1) Systolic blood pressure and diastolic pressure in nieardipine group were significantly decreased before induction after premedication. 2) After induction systolic blood pressure increased in both group (p<0.005) but increasing rate was significantly less than in nicardipine group (p<0.005). 3) After intubation diastolic pressure decreased significantly in nicardipine group (p<0.005). 4) The changes of heart rate were no difference in both groups.

Cerebrovascular accident (CVA) is the most common cause of neurologic disorder accompanying grave prognosisand its mortality above 50%. Prior to introduction of the CT, the diagnosis have been depended on clinicalfindings and spinal puncture. Radiologic diagnostic methods, such as angiography, ventriculography andradioisotope scanning are invasive and less sentitive in diagnosis of CVA than CT. The size, location andextension of the intracranial pathology and ventricular penetration are accureately and rapidly portrayed by CT.Consequently, CT plays impotant role in effective tratement and evaluation of prognosis in CVA. Authors analyzed63 cases of diagnosed CVA who were performed CT scan in Korea General Hospital from November 1981 to April 1982.The results were as follows. 1. The most prevalent age group of CVA was 6th decade, and then 7th and 5th decadesin decreasing order. The sex ration between male and female was 1.2:1. 2. The causes of CVA were hypertensivehemorrhage (50.8%), vascular occlusive disease(22.2%), anurysm ruture (4.8%), arteriovenous malformation (3.2%)and hemorrhage of unknown etiology (19.0%). 3. The most common site of hemorrhage was basal ganglia (34.6%) andthen thalamus(21.8%) and cerebral lobes(20.5%). In infarction, the common sites were the lobes(64.7%) and thebasal ganglia (35.3%) 4. Round or oval shaped hematomas of high density (85.9%) were frequent findings ofhemorrhage and mass effect occured in 75.6%. 5. All infarctions were low in density ; Most of the lesion wasinhomogeneous(70.6%) and the rests were homogeneous. Mass effects were seen in 29.4%.

Diagnostic ultrasound has become one of the most useful tools in the practice of obstetics. It has been ofparticular utility in the placental localization. We analyzed 34 patients of placenta previa scanned byultrasound. The reults were as follows; 1. The age of patient ranged from 22 to 39 years, showing the highestincidence in 26 to 30 years. 2. The accuracy of correct localization was 70.6%. 3. Among 13 cases diagnosed byultrasound as total placenta previa, 2 cases were partial placenta previa and 1 was low-lying placenta at the timeof delivery. 4. Among 9 cases diagnosed by ultrasound as partial placenta previa, 1 case was total palcenta previaand 1 case was low-lying placenta and 1 case was upper segment placenta. 5. Among 10 cases diagnosed by utrasoundas low-lying placenta, 2 cases were partial placenta previa. 6. Among 2 cases diagnosed by utlrasound as uppersegment placenta, 1 case was total placental previa and 1 case was partial placenta previa. 7. Among 9 cases doneserial ultrasoud, 3 cases revealed that the placenta migrates toward fundus in the course of pregnancy, Therefore,the palcental scanning should be repeated in the last month before term to decide the mode of delivery.conclusively, ultrasonography is the imaging modality of choice in the evaluation of placental localization becuseit provides speedy and repeatable way without any known risk to both mother and fetus itself. Careful performanceand accurate interpretation shold be needed for more correct palcental localization.

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.

Ultrasonograhy, it's excellent ability of differentiating cystic from solid lesion and depicting detailedarchitecture, proved itself useful in the diagnosis of thyroid pathologies. Adanced high resolution equipmentsmade hidden small lesion detected and finer structure clearly seen. They seemed to throw light on the histologicaldiagnosis of thyroid diseases, especially differentiation of benignancy and malignancy. Author reviewed picturesof high-resolution ultrasonography of thyroid disease(24 ases0 and correlated them witn proven pathologicalfindings. The results were as follows: 1. Multiplicity of lesion favors benignancy(4 cases). 2. Well definedmargin favors benignancy(14/17), while ill defined margin favors malignancy(3/4), and lesion of no margin favorsthyroiditis(3/3). 3. Surrounding halo favors benignancy(7 cases). 4. Hypoechogenicity were found in most ofmalignancy and thyroiditis. Cystic components in solid nodule were common findings in bening and malignantlesions. Calcification was not found in malignancy.

In evaluation of head trauma, simple skull examinations have been almost routinely requested in emergency room, regardless of historical, physical or neurologic findings, for fear of an unexpected fracture and medicolegal problem. Considering the low yield rate of positive radiologic findings for skull fracture and poor correlation of skull fracture with intracranial sequelae, simple skull examinations in head trauma patients, especially in those with minor trauma, is overutilized without reasonable clinical criteria of application. A retrospective review of 1,101 patients was performed to evaluate the efficacy of simple skull examination at the point of diagnosis and treatment, and to predict the risk for skull fracture and significant intracranial sequelae by clinical findings. Eighty-six patients(7.8%) had skull fractures including two basilar fractures and 12 depressed fractures. 116 patients(10.5%) had significant intracranial sequelae and 62 of these had skull fractures. Of 1,101 patients, 237 had the clinical findings of "high-yield" features and 70 of these had skull fractures and 99 had intracranial sequelae, so high-yield fractures are very indicative for the skull fracture and intracramal sequelae. Only in nine patients(0.08%0 the managements were altered after simple skull examination in that two with basilar fractures were treated with antibiotics and seven with depressed fractures were undergone neurosurgical precedures. Patients who were not admitted nor required further study or treatment because of minor head traumadidn't have any skull fractures or intracranial sequelae in our series, and 62 of 116 patients with intracranial sequelae showed normal skull findings indicating that normal findings can create false sense of security.
