Among 7,500 patients whom we have performed gastrofiberoscopy from July 1979 to June 1,982, 226 cases of stomach cancer were diagnosed. The frequency was 3. 0%. The ratio of male to female was 2: 1, the peak incidence, 69 cases(30.5%) was in 5th decade. 1) The frequency of stomach cancer among the age were 0. 5% in 1st decade, 0.4% in 2nd decade, 1.2% in 3rd decade, 2.5% in 4th decade, 5.9% in 5th decade, 12.6% in 6th decade 16.8% in 7th decade.

BACKGROUND AND OBJECTIVES: Recent data about trans-radial approach showed its usefulness in achieving the high procedural success rate and low local complications even though the size of the radial artery is small compared to that of the femoral artery. Therefore, we want to evaluate the size of the radial artery and the feasibility of the trans-radial coronary angiography as a routine technique. MATERIALS AND METHOD: Trans-radial coronary angiography (TRCA) was successful in 619 cases. The size of the radial artery was measured using 2D-ultrasonography. TRCA was tried with 4 Fr catheters. We divided the cases into two groups; early phase, 106 cases and late phase, 513 cases and compared the procedure time, catheter number used, and complications between 2 groups. RESULTS: The size of the radial artery was 2.7+/-0.4 mm in diameter and this of the men was larger than that of women (p 0.05). TRCA was performed successfully in 513 cases among 521 cases of late phase (98.5%) and crossover to femoral artery occurred in 8 cases (1.5%). The fluoroscopic time and total procedure time of the late phase (6.5+/-4.0 min, 22.9+/-11.3 min) were significantly lower than those of early phase (11.5+/-6.3 min, 31.2+/-13.7 min) (p<0.01). The average number of catheters used for coronary angiography was 1.8+/-1.0. There were 6 cases (1%) of radial artery occlusion and 1 case (0.2%) of radial artery perforation without hand ischemia. CONCLUSION: Based on the adequate size of the radial artery, high success rate and low complications, TRCA might be a safe and become a routine diagnostic technique.

A 21-year-old woman found to be hypertensive was referred for hypertension. On examination, blood pressure was 170/110mmHg in the right arm, 160/100mmHg in left arm,and 120/70mmHg in legs. A grade 2/6 systolic ejection murmur was present at the left upper sternal border, and a chest x-ray revealed a rib notching on the inferior margin of 4th rib. Two-dimensional echocardiogram showed the coarctation of aorta beyound the origin of the left subclavian artery. Biplane TEE demonstrated a discrete narrowing of the descending aorta at the site of coarctation. The blood pressure was 169/86mmHg in ascending aorta and 118/84mmHg in descending aorta. Aortogram showed a localized coarcted aortic segment of 7mm in diameter and 5mm long just distal to the left subclavian artery. Balloon coarctation angioplasty was performed with 7F 30x15mm pediatric balloon dilatation catheter. Balloon position was confirmed on fluoroscopy by the hourglass appearance of the balloon inflation and thereafter, the balloon was inflated until the waist of the balloon disappeared. After procedure, a pull back pressure tracing across the coarctation of aorta revealed no pressure gradient between ascending and descending aorta with 141/90mmHg. Aortogram showed an increase in diameter of the coarctation of aorta to 18mm with aneurysmal formation. 3 months later, follow up aortogram showed no significant change in diameter of coarctation of aorts or aneurysmal formation. Nonsurgical balloon coarctation angioplasty appears to be an alternative therapy for the coarctation of aorta in adults.

It is well known that intracranial hemangiopericytoma commonly metastasizes elsewhere in the body, especially bone and lung. However, brain metastasis of extracranial hemangiopericytoma is very rare. The authors report a case of intracranial metastatic hemangiopericytoma from pelvis in a 41 year old woman. Neurogic symptoms developed 14 months after discovering the pelvic mass. After surgical excision, the clinical course was improved.

PURPOSE: To report glare disability measured by a glaremeter. METHODS: Glaremeter values were measured in 270 normal eyes and 100 pseudophakic eyes. The normal eyes were classified into 3 age groups (teenage to 60's) with 90 eyes in each group. The pseudophakic eyes were classified into the monofocal IOL (intraocular lens) and multifocal IOL implanted groups with 50 eyes in each group. Glaremeter values of each group were measured using a glaremeter under photopic (82.2 +/- 5.1 cd/m2) and mesopic (5.5 +/- 0.3 cd/m2) conditions. RESULTS: The highest mean glaremeter value in the normal eyes was 8657.34 +/- 691.04 mm2 under the photopic condition and 8837.97 +/- 805.83 mm2 under the mesopic condition in the oldest group. The glaremeter value of the multifocal IOL implanted group was 9390.87 +/- 846.7 mm2 under the photopic condition and 9799.87 +/- 823.72 mm2 under the mesopic condition, which was significantly higher than the normal eye and the monofocal IOL implanted groups (p < 0.05). CONCLUSIONS: In the normal population, the mean glaremeter values were increased according to age, and a significant increase was observed in the multifocal IOL implanted group. The present study results provide good basic data for cataract and presbyopia refractive surgery predicted to produce glare disability inevitably.

BACKGROUND: Antibradycardia pacemaker is one of the treatment modalities for bradyarrhythmia. We present the clinical results of 440 implantations of permanent pacemaker between August 1984 and December 1997 at Department of Internal Medicine in Seoul National University Hospital. METHOD: We investigated the indication of permanent pacing, the pacing modes, the complications of permanent pacing, and the chronic pacing threshold. RESULT: The study was comprised of 440 patients (M/F : 179/261, mean age : 59+/-12 years, 58+/-14 years, respectively). Indications of the primary pacemaker implantations were sinus node dysfun-ction in 53% and atrioventricular conduction disorders in 47%. Twelve percent of total pacemaker procedures were pulse-generator replacements. Pacing modes were VVI in 59.1%, VVIR in 10.2%, DDD in 30.2%, and others in 0.5%. Complications developed in 21 cases (4.8%) during long-term follow-up. They included 8 cases of pacing failure due to increased pacing threshold, 2 cases of early power depletion, 2 cases of lead dislodgement, 6 cases of lead fracture, 3 cases of skin erosion, 3 cases of hematoma, 3 cases of infection, and 1 case of skeletal muscle stimulation. Chronic pacing thresholds at pacing width of 0.5 msec were 1.9+/-0.4 V for the epicardial ventricular leads (n=11), 1.3+/-0.5 V for the endocardial ventricular leads (n=36), and 1.1+/-0.2 V for the atrial leads (n=4) after 7 to 10 years of implantation. CONCLUSION: Sinus node dysfunction was the more common indication than atrioventricular block for the antibradycardia pacemaker implantation. Long-term follow-up of the pacemaker patients would be very useful to detect the pacing system abnormalities and to maximize the battery longevity by adjustment of pacing output according to the level of chronic pacing threshold.
