The study was undertaken to assess the ventricular system of the brain in normal korean adults on the base ofCT. The computerized tomographic examinations of 334 Korean adults between ages of 15 to 50 years, performed atSeoul National University Hospital, were evaluated. The known to be a reliable indicator of the ventricular size.This ratio was measured at the level of the lateral, third and fourth ventricles respelctively. The shape of thequardigeminal and suprasellar cistern was analyzed. The resuls are as follows; 1. The cerebroventricular ratios ofthe lateral ventricle at the level of the widest bifrontal and bicaudate diameters were 0.30±0.04 and 0.14±0.02,respectively. The lateral ventricle was asymmetric in 12.6%, of which the left side was usually larger than theright. 2.There was correlation between the cerebroventricular ratio and age, i,e., with increase of age, the C-Vratio increased slightly. 3. The cerebroventricular ratio of the third ventricle was 0.03±0.01. 4. Thecerebroventricular ratio of the fourth ventricle in width and height was 0.14±0.02 and 0.10±0.03, respectively.The anteroposterior position index of the fourth ventricle was 0.42±0.04. 5. The quadrigeminal cistern showedU-shape in 23.4%. 6. The suprasellar cistern showed pentagonal shape in 61.1%, round in 28.4% and hexagonal in10.5%. 7. There was no significant difference between male and female according to the above results.

PURPOSE: To evaluate the clinical patterns of corneal erosion induced by contact lens wear and the relations of corneal complications to the duration of contact lens wear and the final wearing. METHODS: We have examined with slit lamp and questionnaire survey, 161 eyes of 105 patients with complication of contact lens wear who visited KyungHee Medical Center from January 2000 to June 2001. RESULTS: Majority of the corneal complication is diffuse punctate type that comprises 58.3%, corneal erosion 14.4%, corneal ulcer 3.1% and so on. Erosional grading and the final wearing time are not proportional to the clinical presentation. Extended-wear soft contact lens was used by 37.1% and RGP lens by 35.2%. Half of the symptoms starts shortly after the lens removal. Corneal ulcer has a significantly higher incidence in the long-duration of wearing group. CONCLUSIONS: The corneal complication is various as corneal erosion, corneal ulcer, and so forth. Consequently, it is quite necessary to give an intensive education to the contact lens wearers, especially in long-duration ones.

Between 1984 and 1996, 8 patients who were suffered from stage g Kienbock's disease underwent interpositional arthroplasty using pronator quadratus pedicled bone. Patients comprised 2 males and 6 females, with an average age of 33 years(range 19-47). Range of motion of the wrist, residual pain, grip strength, and carpal height ratio of the patients were analyzed. The follow-up period was between 1.5 years and 12.5 years(average 5.5 years). The arc of flexion-extension of the wrist was increased from average 74 degrees preoperatively to 96 degrees postoperatively. Among eight patients, five were free of pain and three had intermittent pain during heavy work. None of eight patients had any discomfort in daily work and changed his or her occupation. The grip strength was average 83% of the normal side. Carpal height ratio was average 0.48 preoperatively and was not changed postoperatively. Clinical results, assessed by Lichtman-Evans criteria, showed 4 good and 4 fair. The interpositional arthroplasty using pronator quadratus pedicled bone was considered as a very effective method for the treatment of stage III Kienbock's disease.

ERCP was performed in 34 cases of obstructive janndice at Busan National University Hospital between June 1981 and October 1982, and those findings were compared with the final surgical operative diagnoses. The results were as follows: 1) The ratio of male to female was about l. 6: 1 and most of them were in the 5th decade to 7th decade, 2) Upper abdominal pain and tenderness were the cardinal symptom and sign, 3) Successful ERCP was obtained in 32 cases among the total of 34 cases(94.1%)Selective success rates by indications were 77.8%(21/27) in suspected biliary lesions and 85.7%(6/7) in suspected panceatic lesions. 4) ERCP diagnoses were biliary stone(11 cases), eholangiocarcinoma(6 cases), pancreatic head ca. (4 cases), Ampulla of Vater ca. (2 cases), normal cholangiogram(2 cases), and normal parcreatogram(2 cases). 5) Eighteen cases out of 24 surgical operative cases were diagnosed by ERCP alone, The diagnostic rates of ERCP by surgical operation in obstructive jaundce was 75%. Complications of ERCP were not clinically significant. It suggests that ERCP is a very useful diagnostic method in the differential diagnosis of obstructive jaundice.

PURPOSE: To evaluate the usefulness of 3 dimensional-volume MR imaging technique for demonstrating the facial nerves and to describe MR findings in facial palsy patients and evaluate the significance of facial nerve enhancement. MATERIALS AND METHODS: We reviewed the MR images of facial nerves obtained with 3 Dimensional-volume imaging technique before and after intravenous administration of Gadopentetate dimeglumine in 13 cases who had facial paralysis and 33 cases who had no facial palsy. And we analyzed the detectabilty of anatomical segments of intratemporal facial nerves and facial nerve enhancement. RESULTS: When the 3 Dimensional-volume MR images of 46 nerves were analyzed subjectively, the nerve courses of 43(93%) of 46 nerves were effectively demonstrated on 3 Dimensional-volume MR images. Internal acoustic canal portions and geniculate ganglion of facial nerve were well visualized on axial images and tympanic and mastold segments were well depicted on oblique sagittal images. 10 of 13 patients(77%) were visibly enhanced along at least one segment of the facial nerve with swelling or thickening, and nerves of 8 of normal 33 cases(24%) were enhanced without thickening or swelling. CONCLUSION: MR findings of facial nerve paralysis is asymmetrical thickening of facial nerve with contrast enhancement. The 3 Dimensional-volume MR imaging technique should be a useful study for the evaluation of intratemporal facial nerve disease.

Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective. However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experierced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction .by anterior spinal arteri. al occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment.

We experience a case of 34-year-old Turner's syndrome(45, XO) associated with atrial septal defect(secondum type) and mitral valve prolapse who was admitten due to moderate exertional dyspnea. It is well know hat chromosomal abnormality is one of the etiology of congenital heart disease. In case of Turner's syndrome, coarctation of aorta or bocuspid aortic valve is frequently combined, but atrial septal defect simultaneously with mitral valve prolapse is not reported till now in Krea. We report this case with a brief review of the literature.

BACKGROUND: This clinical trial was performed to evaluate the hemodynamic and side effects of enoximone, a newly developed phosphodiesterase inhibitor, in moderately severe congestive heart failure in Korean population and to base the development of long acting oral preparations in the future. METHODS: Principal admission criteria for this trial were a left ventricular ejection fraction of less than 45% by radionuclide ventriculography, NYHA functional class II or III and a documented congestive cardiomyopathy. Exclusion criteria were restrictive cardiomyopathy, valvular heart disease, multisystemic lillness and uncontrolled ventricular tachyarrhythmia. The hemodynamic measurements were made by using the thermodilution Swan-Ganz catheter and radial arterial canulation. Enoximone was administered(continuous infusion) for 24 hours after initial bolus. The hemodynamic parameters to be observed were blood pressure, heart rate, cardiac output, pulmonary capillary wedge pressure, systemic and pulmonary vascular resistance. The clinical reponse, hematology, blood chemistry, and Holter monitoring were checked before and after enoximone trial. RESULTS: The following results are obtained. 1) The included patients were 15 females, 24 males, total 39 patients and mean age of 55.3 years old(28-70 years old). 2) The causes of congestive cardiomyopathy were idiopathic 35(89.9%), hypertensive 3(7.7%), and alcoholic 1(2.6%). 3) The mean ejection fraction measured by radionuclide left ventriculography were 28. 6%. 4) THe cardiac output was significantly increased(50%), and pulmonary capillary wedge pressure(38%), systemic vascular resistance(34%), pulmonary vascular resistance(27%) were significantly decreased during enoximone infusion. 5) NYHA Functional Class was improved by 1 step with enoximone. 6) There were no significant changes in hematology, blood chemistry, and Holter monitoring with enoximone. CONCLUSION: From the above results, the short term intravenous enoximone was very effective in moderately severe congestive heart failure in congestive cardiomyopathy without major adverse effects in Korean.

Since selective serotonin reuptake inhibitors were introduced in clinical practice in the 1990s, antidepressant prescriptions have steadily increased. In addition to the prescriptions by psychiatrists, antidepressant prescriptions by non-specialists have also increased. An advanced understanding of the pharmacological and clinical characteristics of antidepressants is essential to improving the treatment response of depressive disorders and the quality of life of patients. Antidepressant withdrawal or discontinuation syndrome can frequently occur if antidepressant maintenance is discontinued without a pre-planned clinical strategy. Nevertheless, it is often unrecognized or mistaken for other clinical situations. This causes patient distress and ultimately reduces long-term treatment compliance. Inappropriate therapeutic decisions can be made if clinicians do not recognize antidepressant discontinuation syndrome. Antidepressant withdrawal is common and preventable. This issue must be recognized because it can be adjusted through appropriate clinical management. This article systematically reviews the clinical features, biological mechanisms, coping strategies, and antidepressant discontinuation strategies related to antidepressant discontinuation syndrome.
