Reconstruction of partial ear defect to approximate the opposite normal ear is actually very difficult. Because the patterns of partial ear defect (site, shape and size of defect) are extremely variable, the operative method on each case should be changed. In an effort to overcome these problems, many reconstructive methods have been reported so far. We experienced 11 cases of partial ear defect from September, 1995 to August, 1996 and different reconstructive methods were applied In this study, the most common cause of partial ear defect was trauma (9 cases) and the most common site was middle part of ear helix. The defects were varying from 1x2 cm to 1.5x5 cm in size. The methods that has been used for reconstruction of ear defect include direct closure, helical chondrocutaneous advancement flap, Dieffenbach's method, retroauricular flap, tubed bipedicled flap and so on. We could get to know the merits and demerits of each method through this follow up study. So authors obtained the several basic conclusions about the merits and demerits of each method and standard of method selection in various patterns of ear defects. From analysis of the cases with review of literature, the our conclusions are as follows. 1. If the size of de(tract is small and the patient does not want to have two times of operation, direct closure can be done with good results. 2. If the defect exists on ear auricle confuted to helix and if there are no or small amount of associated cartilage defect, tubued bipedicled flap seems to be proper. 3. With the ear auricle defect confined to helix, especially helix of upper ear auricle, helical chondrocutaneous advancement flap can brought tile best result, though it has disadvantage of being decreased in its size 4. If there are extensive defect on ear auricle extending over scapha and antihelix, retroauricular flap can be done with good results. 5. In the ear auricle defect acompanying considerably large cartilage loss, Dieffenbach's method is thought to be proper.

Hurthle cell tumors are an infrequent neoplasm of the thyroid gland in adults. Hurthle cell tumors represent 4. 5% to 10% of all primary thyroid epithelial neoplasms in the foreign literature. It has been known as Hurthle cell tumor since Ewing was the first to use this term in 1928. Tumor occurring in an infant was described by Symmers(1941) and Morrow(1945). The authors experienced a case of congenital Hurthle cell tumor of the thyroid gland in a 2 months old boy. He was admitted to the pediatric surgical department because of a growing mass in the neck since birth. Ultrasonogram showed a huge lobulated homogenous solid mass with medium level echogenicity in the region of the thyroid gland. Subtotal thyroidectomy of right lobe and total thyroidectomy of left lobe were done. The specimen measures 2x3x1.5 cm and 7x3x3 cm, respectively. It was an encapsulated, yellow gray firm and solid mass. The cut surface was smooth, glistening and homogenous. Microscopicully, the tumor was composed of tightly packed regular follicles lined by polyhedral, cuboidal, large cells with a granular acidophilic cytoplasms. The nuclei are vesicular, usually only a little bit larger than those of normal thyroid cells.

OBJECTIVE: As an electronic health record system is implementing in Korean health care sectors, concerns about key functionalities of electronic health record systems are increasing. The purpose of this study was to identify core functions and set the priority in electronic health record systems under the Korean contexts in order to assure and improve the quality of the systems. METHODS: A survey was conducted using questionnaire developed by the study team based on literature review. The subjects were medical record administrators working at medical record department in general hospitals. RESULTS: The response rate was 59.8%(55/92). The functions which more than ninety percent of subjects responded as necessary right now and/or in near future related to 'drug alert', 'clinical guideline', 'chronic disease management', 'automated real-time surveillance', 'coded data', 'result reporting', 'de-identifying data', 'disease registry', and 'provider-provider communication and connectivity'. CONCLUSION: The results showed the high prioritized functions were decision support and health information/data management.

5.Prolongation of Succinylcholine Neuromuscular Blockade by Lithium Carbonate.
Korean Journal of Anesthesiology 1988;21(3):502-504
Lithium, first used by Cade in 1949 for the treatment of mania, is now commonly used in several affective disorders. The precise mechanism of its action is not clearly understood but the side effects may be severe. Prolongation of succinylcholine and pancuronium which possible mechanism of interaction involves impaired acetylcholine synthesis and release at nerve terminal has been reported. The present report describes a case of prolonged neuromuscular blockade induced by succinylcholine in a manic depressive patient being treated with oral lithium carbonate.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.
