Aortic regurgitation is a common valvular heart disease, usually the result of rheumatic fever, or syphilis, and rarely of congenital origin. It is frequently associated with other valvular heart disease, especially mitral valve disease. It can be diagnosed by the presence of pulse pressure widening, a Corrigan pulse, and an early decreascendo diastolic murmur at the left sternal border between the second and third intercostal spaces. After the clinical application of cineaortography in the diagnosis of valvular disease, Segal et al (1964) first reported rheumatic aortic regurgitation without an audible murmur in patients having mitral valve disease. The importance of discovering aortic reguritation in patients with predominent mitral disease has begun to be appreciated recently, especially as commisurotomies for the relief of mitral stenosis are performed more frequently. Nowadays eventhough the severity of aortic regurgitation is often not evident preoperatively, aortic regurgitation can become very evident when mitral stenosis is relieved. This study was comprised of seventeen patients with silent aortic regurgitation which was confirmed by cineaortography at Severance Hospital from January, 1970 to August, 1976. 1. Of the seventeen patients, 12 patients were associated with mitral stenosis, 4 with mitral steno-insufficiency, and 1 with mitral insufficiency. 2. Silent aortic regurgitation was suggested from the accompanying clinical features such as chest pain, apical heaving, and left ventficular hypertrophy pattern on both roentgenogram of the chest and electrocardiogram. 3. The severity of the aortic regurgitation was mild to moderate; 7 of the 17 patients being grade I, and 10 patients being grade II on cineaortogram.

Various methods of taking of optic foramen view and avalubilities have been studied by many foreigninvistigators, but those in Korea have not been reported yet. The authors have measured and examined the size andshapes of optic foramina of optic foramen views in 111 Korean checked at Inje Medical College Hospital duringabout 3 years form June 1979 to March 1982. The cases were divided into gwo groups, A and B, for the convenienceof study. Group A consisted of 50 normal Korean 5 to 55 years of age with no visual symptoms and signs. Group Bincluded 69 patients 3 to 75 yrs of age with visual symptoms and signs. The results were as follows; 1. Mean valueof actual diameter of optic foramen meassured by Goalwin's method in Group A; Right; A diameter; 4.21mm, Bdiameter; 4.32mm, Left; A diameter; 4.29mm, B diameter; 4.30mm. 2. Absolute symmetry of the greatest diameters ofboth optic foramina in Group A; 36%, difference of 0.5 or lessl 28%, from 0.5 to 1.0mm; 18%, from 1.0 to 1.5mm;8%, uncomparable cases; 10%. The greatest difference was 1.4mm. 3. The shapes of optic foramen in Group A; ovalshape; 65%, circular ; 29%, keyhole or double foramen; 6%. 4. In Goup B, the peak age group was second decade(31%), the most comon clinical cause of examiniation of optic foramen view was optic nerve atrophy(30%), and thepathologic findings were only 4 cases(7%). 5. The technique of optic foramen view by modified Pfeiffer's methoddelineated the outline of optic foramen more clearly than ordinary Rhese's method in our experience.

Since the residency training program in internal medicine changed from a four-year to a three-year program in 2017 in Korea, issues of an optimal training program for the gastrointestinal (GI) fellowship has arisen. Currently, the evaluation criteria for a GI fellowship in Korea include the following; 1) the total number of assigned patients during the training period, 2) the number of GI endoscopy procedures, 3) attendance at academic conferences, and 4) research presentations. However, competency-based training should be introduced in the GI fellowship training program. The current issues of GI fellowship training in Korea include the following; 1) reorganization of the GI fellowship education system and consideration of an optimal training period following the introduction of the three-year internal medicine residency training program, 2) development of a standardized, competency-based GI fellowship training program, 3) provision of a support program for instructors in GI fellowship education, 4) introduction of a mentor-mentee system, 5) introduction of an accreditation system for GI fellowship, 6) supplementation of a GI sub-specialty qualification system, and 7) provision of benefits to GI sub-specialists.

Chemotherapy offers palliative treatment to patient with advanced nonresectable hepatoma. The usefulness of systemic chemotherapy is limited becaused of serious side reaction and low concentration of drug at tumor. Butthis problem may be overcome by intraarterial infusion. Nonsurgical percutaneous hepatic arteiral catheterizationwas done in 21 patients with primary hepatoma, and infusion chemotherapy was done in 19 patients who were successful in catherization. The results were as follows; 1. Selective catheterization of hepatic artery proper,common hepatic artery, and celiac artery were seccessful in 4, 9 and 4 patients, respectively. The success rate ofselective catheterization is 80.9% including celiac artery among 21 patients with hepatoma. 2. Simple catherization method was applied in 14 patients, and catheter exchange and Loop methods were applied in 2 and 1patient respectively. 3. Complications related to catheterization, such as infection and bleeding on punctured site, intimal injury and dislodgement of catheter were not serious. 4. Drugs were well tolerated without serioustoxicity or complication. 5. 3 patients showed objective response and median survival time of treated patients is 2.5 months.

To evaluate the clinical utility of Tc-99m MIBI scan in the detection of residual thyroid tissue or metastatic lesion in postoperative thyroid cancer patients, we compared Tc-99m MIBI scan with I-131 diagnostic and therapeutic scan in 30 postoperative well-differentiated thyroid cancer patients. Thyroglobulin levels of both on and off thyroid hormone medication and antithyroglobulin antibody were tested [Tg(on), Tg(off)l Positive rates for I-131 diagnostic and Tc-99m MIBI scan were 81% and 68% respectively. Concordance between I-131 diagnostic and Tc-99m MIBI scan was observed in 15 cases; 12 positive and 3 negative respectively Among the 6 cases with negative I-131 diagnostic scan and positive Tc-99m MIBI scan, 4 were positive in the therapeutic I-131 scan. We concluded that Tc-99m MIBI scan maybe a useful complementary modality to the currently established method of I131 scan and serum thyroglobulin level in the detection of recurrent or metastatic thyroid cancer, especially in the case of negative I-131 diagnostic scan.

To evaluate the utility of I-131, T1-201 scintigraphy, and serum thyroglobulin(Tg) in the follow-up of differentiated thyroid cancer, we compared retrospectively the data from 33 patients who underwent total or subtotal thyroidectomy. I-131 scintigraphy was performed after optimal endogenous TSH stimulation (TSH>50microgram/ml). Total 41 cases of I-l3l and T1-201 scintigraphy pairs were examined. Concomitant serum thyroglobulin levels were measured for 41 pairs of scan. Tg-off levels(that measured after discontinuation of the thyroid hormone) higher than 40ng/ml were considered positive, and Tg-on levels(that measured during the thyroid hormone replacement) higher than 5ng/ml were considered positive. The concordance rates between I-131 therapeutic scintigraphy and T1-201 scintigraphy was 48% in the 38 case of total scan pairs(59% in the 17 cases of postoperative preablation group, and 38% in the 21 cases of postoperative postablation group), Of 17 studies before the I-131 ablation therapy (preablation group), 7 showed positive I-131 therapeutic scintigraphy despite of negative T1-201 scintigraphy. Among patients with negative I-131 therapeutic scintigraphy, no patients had abnormal T1-201 uptake. However, of 21 studies which were done after radioiodine therapy(postablation group) 6 had abnormal uptake on T1-201 scintigraphy which were not seen on I-131 therapeutic scintigraphy, and Tg-off levels also elevated in this 4 of 6 cases. As a result, I-131 therapeutic scintigraphy showed highest positive rate at postoperative preablation follow-up study in differentiated thyroid cancer patients. T1-201 scintigraphy may be useful in postablation studies, and the use of the combined modalities(T1-201 and Tg levels) provides a higher diagnostic yield.

We report on a case of torsion of an accessory spleen occurring in a 19-year-old female. She was admitted with a three-day history of left-upper quadrant pain that became slowly aggravated. On physical examination, left-side abdominal tenderness was observed, most markedly in the left upper quadrant, but no rebound tenderness was noted. Contrast-enhanced computed tomography (CT) scan showed a non-enhancing mass with a tubular vascular pedicle and normal enhancing spleen in the left upper abdomen. Doppler ultrasound showed no vascular flow within the hypoechoic mass in the left upper abdomen. Torsion of an accessory spleen was suspected, and emergent laparoscopic exploration was performed. Laparoscopic exploration showed a large rounded violet mass with a tw isted vascular pedicle, located anterior to the normal spleen. The mass was excised laparoscopically and then removed through a 2.5 cm extended incision of the left-sided trocar incision. Postoperative recovery was normal and she was discharged on the fifth postoperative day.

PURPOSE: Percutaneous pin fixation is commonly applied for pediatric diaphyseal forearm fractures. We analyzed the results of percutaneous transphyseal intramedullary K-wires fixation for pediatric forearm fractures and evaluated the safety of this procedure in terms of growth. MATERIALS AND METHODS: Thirty-six pediatric patients with forearm diaphyseal fractures treated with transphyseal intramedullary K-wire fixation were reviewed retrospectively. Authors analyzed size and number of fixed K-wires and evaluated postoperative complications, bone length discrepancy and any deformity at the last follow-up. We also evaluated range of motion of wrist and forearm as a functional result. RESULTS: The mean age was 9.5 years old and the average period of follow-up was 53 months (range: 23-85 months). Single wire was applied in each bone, and 1.6 mm sized K-wire was most commonly used for radius fractures and 1.1 mm K-wire for ulnar fractures. There was one superficial pin site infection which was healed by conservative treatment. There were no other complications such as premature epiphyseal closure, discrepancy of forearm length or any deformity. All patients showed no significant difference in range of motion compared to opposite side at the last follow-up. CONCLUSION: Percutaneous transphyseal intramedulaary K-wire fixation is one of the effective and safe operative treatment for pediatric forearm fractures without any deleterious effects on subsequent growth of radius and ulna.
