Cubitus varus, which includes deformities of varus, hyperextension and internal rotation, is the most common complication of supracondylar fracture of the humerus in children. For correction of cubitus varus deformity, many operative methods have been reported but postoperative results are not always satifactory. For the purpose of detection of the reason of postoperative residual deformity, we reviewed AP roentgenography of 22 patients of cubitus varus deformity in the view point that change of longitudinal axis of forearm contribute the residual deformity. The results are summerized as follows: 1. Degree of cubitus varus deformity was more severe in the patients whose interval between the injured time and visiting hospital for cubitus varus was longer. 2. Average proximal radial shaft angle was 10.99degrees +/-3.48degrees in normal limb and 15.72degrees+/-4.03degrees in affected limb and average ulnar shaft angle was 7.86degrees+/-3.60degrees, 10.54degrees +/-4.02degrees (P<0.05), respectively which were all significant value statistically (P<0.05). Average distal radial shaft angle was 10.21degrees 2.37 in normal limb and 11.21degrees +/-1.51degrees in affected limb and statistically insignificant (P>0.05). 3. More severe cubitus varus deformity revealed more change of proximal radial shaft angle of attected limb compare to normal limb. Based on these results, we concluded that correction of the cubitus varus deformity should not be delayed in order to minimize the secondary change of longitudinal axis of foream bones and to obtain satisfacotry cosmetic outcome.

This study was performed to investigate the effect of kimchi intake on free radical and oxidative substance production in young adults and the elderly. Daily kimchi intake by people in their twenties (n = 93, 20 to 29 years old) and over sixty-five (n = 143, over 65 years old) in M city were surveyed and blood was drawn to analyze the free radicals in their plasma. The average amount of kimchi intake by the subjects was 115.8 +/- 91.7 g. The amount of kimchi intake of those in their twenties (106.1 +/- 80.6 g) was significantly lower than that of those over sixty-five (125.5 +/- 102.9 g, p<0.05). Concentrations of total free radicals and OH radicals were 27 and 33% greater respectively, in those over sixty-five than in those in their twenties, indicating that more free radicals were produced by the older group. The concentration of GSH was not signiacantly different in the two groups, but that of GSSG in the over sixty-five age group was 53% greater than in the twenties group, which resulted in a 35% reduction in GSH/GSSG in the elderly group. TBARS concentration in the over sixty-five group was 26% greater than that of the twenties group. In order to see the effect of kimchi intake on free radical production, subjects in same age group were divided into two sub groups-the mean over and the mean under groups-according to the average amount of kimchi intake, which was 115.8 g. The total free radicals, the OH radicals, the GSH, the GSSG, and the GSH/GSSG in the twenties group were not significantly different in the two kimchi intake groups. However, those in the over sixty-five group were significantly different. The concentration of total free radicals and OH radicals of the mean over group were 21 and 26% lower respectively, than those of the mean ova. group (p<0.05). The GSH and GSH/GSSG of the mean ova. groups were higher by 8 and 12%, respectively. The correlation coefficient between the kimchi intake and the total free radicals was -0.1862 (p<0.05) and that for GSH/GSSG was 0.1861 (p<0.05). In conclusion, the production of free radicals and oxidative substances increased with age, and kimchi seemed to retard this phenomena.

BACKGROUND: Onlay vein patch coronary angioplasty has been known to be an option for coronary artery stenosis in the selective iesions MATERIAL AND METHOD: During the period between July 1997 and August 1999, coronary angioplasty using autologous saphenous vein was done on 16 sites in 14 cases for the stenotic lesion at the bifurcation area and significantly stenosis distal to anastomosis. RESULT: Early patency of the angioplasty site was 85.7% at postoperative day 7. There was no statistically difference in graft patency, operative parameters, and complications compared to conventional anatomosis(p>0.05). CONCLUSIONS: Despite the small number of cases, the patency rate of the coronary patch angioplasty was comparable to the conventional CABG. Coronary artery only patch angioplasty could be performed in highly selected coronary arteries.

BACKGROUND: Early patency of the coronary artery bypass grafting is determined mainly by surgical technique and status of coronary artery. We analyzed the early result, focusing on the relationship between postoperative angiographic findings and the patency rate. MATERIAL AND METHOD: During the period of July 1997- August 1999, 86 cases of CABG were performed and the postoperative coronary artery angiography was done in 76 cases on postoperative day 7 to assess the graft patency. RESULT: Overall graft patency was 90.2% on the angiographic finding. Factors influencing the early graft occlusion were the surgeon's experience, small coronary artery size less than 1.5mm in diameter, coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site(p<0.001). Operative mortailty was 2.3%. Early recurrence of the symptom was 19.8% during the follow up period. CONCLUSIONS: We examined the postoperative coronary angiography and found that the surgeon's experience, small coronary artery size less than 1.5mm in diameter, bypass surgery on the coronary arteries related to pre-operative myocardial infarction, and local atheroma at the anastomosis site were the factors for the graft occlusion.

A 65 year-old male had chest pain which was diagnosed as unstable angina needing urgent coronary artery bypass surgery. Physical examination demonstrated signs of severe anemia and hemoglobin level was 5.7 g/dL. Gastrofiberscopy showed a 4 cm sized fungating mass at the lesser curvature with active bleeding. The mass was adenocarcinoma by pathologic examination. Simultaneous coronary artery bypass surgery and total gastrectomy were planned due to bleeding of the mass. Off-pump coronary bypass grafting was done first, followed by total gastrectomy. The postoperative course was smooth. He was discharged from the hospital after 12 days and was on surveillance for 9 months. We report a rare case of simultaneous surgery for angina and gastric cancer.

BACKGROUND: This study was performed to investigate the outcomes of vascular operations that were done in patients with atheroscerosis obliterans (ASO) of lower limb. MATERIAL AND METHOD: Forty patients underwent vascular operations from December 1996 to June 2004. The patient's records were analyzed retrospectively. Mean age was 66+/-8 years (range, 47~81 years). Gender ratio was 37:3 (male:female). RESULT: The operations were done on 50 lower limbs of 40 patients. The names of operations were femoropopliteal bypass in 12 patients (30%), femorofemoral bypass in 12 (30%), femorofemoral bypass and femoropopliteal bypass in five (12.5%), aorta-lower limb artery bypass in five (12.5%), axillofemoral bypass in two (5%), iliopopliteal bypass in two (5%), and endarterectomy in two (5%). All bypass surgeries were done with prosthetic conduits. Mean follow up period was 33.2+/-23.2 months (range, 3.8~90.2 months). The cumulative patency rates of 1 and 5 years were 75.5 and 58.7% respectively. In six patients, amputation of the lower limb was done. In eight patients, 12 complications occurred. After the first operation, 10 patients underwent reoperations. CONCLUSION: Our lower limb arterial bypass surgery revealed acceptable patency rate, but not a few patients required reoperations. An epochal treatment modality that can inhibit the progress of ASO and improve long term patency should be established.

OBJECTIVE: Using Lee et al (1996) model, we assessed the effect of opioid within the PAG on the manifestations of the neuropathic pain, and we studied the effects of naloxone on the analgesic effects of opioid. METHOD: Under pentobarbital anesthesia, male Sprague-Dawley rats were implanted with cannula in the ventral (n=10) and dorsal (n=6) PAG after the unilateral tibial and sural nerves were ligated and cut, leaving the common peroneal nerve intact. Pain sensitivity was assessed using the von Frey filament (8 mN) and acetone applied to the sensitive area for 1 week postoperatively. Rats with neuropathic pain were intracerebrally microinjected with DAMGO (0.1microgram/5microliter) and enkephaline (20microgram/5microliter) into the ventral and dorsal PAG and the pain sensitivity was assessed. Naloxone was injected to assess the observed change of pain sensitivity. RESULTS: Intracerebral microinjection of DAMGO and enkephaline into the ventral PAG, but not the dorsal PAG, increased the pain threshold which was reversed by naloxone. CONCLUSION: The results suggest that stimulation of the ventral PAG in neuropathic rats may reduce neuropathic pain via opioid-mediating pathway of the descending pain inhibition system.

OBJECTIVE: To observe the change of sympathetic skin response (SSR) before and after sympathectomy in patients with idiopathic palmar hyperhidrosis and to find the usefulness of SSR for assessment of the effects of sympathectomy. METHOD: The SSR was measured in 20 patients with palmar hyperhidrosis and 20 normal control group. Ten days after thoracoscopic sympathectomy, SSR was also measured. A 50~150 V stimulus was applied over the median nerve and SSR was recorded on bilateral palms and soles with Viking IV (Nicolet Biomedical Ins., U.S.A.). Patient's satisfaction with operation was assessed by questionnaire. RESULTS: Absent or unstable SSR recordings rate was increased and amplitudes of SSR were significantly decreased in patients with palmar hyperhidrosis compared with control group. After sympathectomy, SSR was absent in all cases on bilateral palms and these results were correlated with clinical improvment. All patients who had undergone surgery showed significant clinical improvement for palmar hyperhidrosis and about 75% of the cases were found to have compensatory sweating from other site of the body. CONCLUSION: Abnormal sympathetic nerve system responses were observed in patients with palmar hyperhidrosis. SSR recordings and clinical manifestations were influenced by sysmpathectomy.

A 32 year-old man was transferred to our hospital due to blood-tinged sputum for 15 days. He had been treated at a private hospital for recurrent pneumonia. The chest X-ray showed an atelectasis on the right middle lobe. Computed tomography of the chest demonstrated a broncholith on right middle lobar bronchus with lobar atelectasis of the right middle lobe. We tried to remove the broncholith through fiberoptic bronchoscopy, but could not remove it. Therefore, we performed surgical removal of broncholith and the right middle lobectomy. The cause of broncholith was identified as actinomycosis by pathologic examination. The broncholith caused by actinomycosis is rare. We report a rare case of broncholithiasis with recurrent obstructive pneumonia caused by actinomycosis, which was treated by surgical operation.
