In management of foot deformity, the operative procedures such as tendon transplantation and bone stabilization are of the relatively recent origin. The first tendon transfer was performed by Nicoladoni in 1881. Since that original report, a voluminous literature was appeared on the subject of tendon trasplantation. During the period, from Jan. 1960 to May. 1992, we have done clinical studies of the 189 feet on 167 patients who had been undergone tendon transfer. The results are as followes, 1. Residual poliomyelitis, leprosy, cerebral palsy and club foot are common etiology. Among them, residual poliomyelitis was the most common, especially in 1960 to 1969. Recently trauma and aged leprosy were increased. 2. Among 189 feet, the equinovaurs deformities were 90 cases. 3. Posterior tibial tendon, peroneus tendons, anterior tibial tendon, Achilles tendon and extensor hallucis tendon were transferred. 4. Posterior tibial tendon was mostly used. 5. The evaluation for surgery, for Good to Excellent was 114 feet 60. 3% 6. The poor results were noticed in the cases of the calcaneal deformity and showed in the age below 5 years old.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.

The present study was designed to estimate the seroprevalence of NLVs among diarrheagenic children and in healthy adults in Seoul and its vicinity with the use of an EIA and an Western blot (WB) based on recombinant Norwalk virus capsid protein (rNV) and crude virus preparations as antigen. Seroconversion was observed in 34 (83%) of 41 tested using the EIA and in 21 (54%) of 39 using the WB, suggesting that the NLVs with epitopes common to rNV are prevalent in Seoul area. Diarrheal children who were known to have been infected with several other strains of the NLVs showed no significant antibody response to the rNV. Infection with rNV occurred earlier in life: primary infections with rNV were common before the age of 6 months and over 91% of children had evidence of infection by that age by the EIA. Since the amount of the NLV antigens available for seroepidemiologic surveys is limited, we tried to detect NLV antibody by using crude virus preparations as antigen. One crude virus preparation of a child whose stool yielded genetically distinct NLV revealed the presence of the plural number of bands upon SDS-PAGE, but precipitated only one band (62 kDa) after the WB with a serum (collected 10 days after the onset of symptoms) of another diarrheal child. The WB assay we present in this report revealed that the NLVs are prevalent among Korean population and that the sera contained antibody to a single major structural protein, with molecular sizes of 58 to 62 kDa, compatible with the sizes reported for the Norwalk virus and Snow Mountain agent proteins, respectively. When the results of the WB were compared with those obtained by the EIA, the EIA antibody assay was sensitive enough to detect an antibody rise of as much as 4096-fold but not as specific as the WB. The WB assay presented in this paper will provide a powerful tool to elucidate not only antigenic structures of the NLVs but also seroepidemiology of the NLV infection. The availability of an unlimited source of antigen will enable a large scale serologic studies that will greatly increase our understanding of the role of NLVs in human enteric illness.

OBJECTIVES: The aim of this study was to evaluate the differences in patients with positional dependent sleep apnea according to their non-supine apnea-hypopnea index (AHI, > or =5 vs. <5). METHODS: 92 patients with positional sleep apnea were evaluated. The patients were divided into two groups : group I was non-supine AHI having > or =5 ; group II was non-supine AHI having less than 5. Statistical analysis was performed to find the difference between two groups. RESULTS: In 92 patients, the number of group I patients was 11 (12%) and the number of group II patients was 81 (88%). In the severe AHI group, percentage of group I was dominated (70%) and showing a significant difference compared with the mild and moderate AHI groups (p<.05). In the severe body mass index (BMI) group, percentage of group I was dominated (54.5%) and showing a significant difference compared with of the mild and moderate BMI groups (p<.05). The percentage of group I was significantly higher than group II (p<.05) in the AHI, supine AHI, non-supine AHI and snore time. CONCLUSIONS: In patients with positional sleep apnea, severe OSA and high BMI are more common in patients with non-supine AHI> or =5 than non-supine AHI<5.

Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origins of the coronary arteries. It may be localized or diffuse, and includes a wide spectrum of pathologic changes. A 16 years old school boy was admitted because of exertional dyspnea for 6 years. Clinical diagnosis of supravalvular and valvular aortic stenosis with bicuspid aortic valves and myocardial hypertrophy was made by echocardiography and angiocardiography. Surgical correction was performed successfully. We presented a case of supravalvular and valvular aortic stenosis with a review of literatures.

Fractures of the distal end of the femur are difficult to manage because of the a wide range of potential complications. In the past, there has been a reluctance toward treatment of fractures of the distal end of femur with internal fixation. Recently, however, a trend toward internal fixation has become evident and good results have been reported by several authors. We analyzed 30 cases of distal femur fracture involving knee joint in the Department of Orthopaedic Surgery in National Medical Center from Jan. 1982 to Dec. 1986. 1. There were 30 cases in 29 patients. And were devided in 23 closed and 7 open fractures. 2. Clinical union were taken from 3 to 5 months in conservative and 2 to 3.5 months in operative treatment. 3. Satisfactory results were 5 cases(64%) in conservstive and 16 cases(73%) in operative treatment. 4. Significant complication were stiffness and infection.

Opposition of the thumb is necessary for pinch-one of the three most important functions of the hand. Frequently, opposition is either partially or totally lost in poliomyelitis or median nerve palsy. Several types of operations have been devised for restoration of opposition, and in 1973, Burkhalter et al. announced extensor indicis proprius opponensplasty: the tendon of extensor indicis proprius is brought out in the area of the pisiform and then passed against subcutaneously across the palm to the thumb, being attached to the abductor pollicis brevis and extensor pollicis longus tendon. It is useful in the case of loss of opposition without available finger flexor or wrist motors. Of nine patients who underwent operation-one with Riordan and eight with Burkhalter type of opponensplasty-at National Medical Center, seven had excellent results: one had a fair, and another one had a poor result. Six patients were with low combined median and ulnar nerve injury: one with high combined median and ulnar nerve injury: one with brachial plexus injury: and one with myotmesis of the thenar muscles. From the results, we conclude that Burkhalter type of opponensplasty makes satisfactory result for the hand without opposition movement; it is indicated in high median nerve injury and any combined median and ulnar nerve injury6; early restoration of opposition to the thumb in median nerve injury and in those limbs with multiple tissue trauma adds immeasurably to the over-all early rehabilitative effort.

Ganglia are the most common soft tissue tumors of the hand. Ganglia found on the dorsum of the wrist usually arise from the scapholunate ligament and are usually located between the extensor digitorum communis tendon of the index finger and extensor pollicis longus tendon. Intratendinous ganglion is a very rare lesion of unknown etiology and natural history that originates within the tendon. A patient is described who presented with a painful mass on the dorsolateral aspect of the wrist due to an intratendinous ganglion of the extensor pollicis longus tendon. Treatment consisted of excision of the extensor pollicis longus tendon with ganglion followed by mini free tendon graft using palmaris longus tendon.
