The Marjolin's ulcer is the malignant lesion developed in a burn scar or chronic fistula. Due to the low prevlalence of this lesion, there has been disagreement in its clinical features, methods of treatment, and prognosis. We evaluated 19 cases of patients who had been admitted to Severence Hospital from Jan. 1970 to Dec. 1958. The results were as follows : 1. The previous lesion was burn scar in 52% of the cases and fistula of chronic osteomyel-itis in 32%. 2. The mean latent period was 31.5 years. 3. The initial symptoms were increased pain(74%), discharge with foul odor(68%) and bleeding(58%). 4. Upon histological examination, all of the cases were squamous cell carcinoma. 5. The rate of recurrence of metastasis at time of diagnosis was 32%. 6. Of the 16 patients treated by surgery, local recurrence was noted in 4 cases. Three of these cases were patients who had been treated by excision and split thickness skin graft. 7. The time interval for local recurrence ranged from 6 months to 11 months(average 8. 8 months). In conclusion, the squauious cell carcinoma of the Marjolin's ulcer seems to have a worse prognosis than other squamous cell carcinoma and it requres aggressive treatment. The burn scar or chronic fistula that occured in elderly patients especially required more adequste treatment and close observation.

A total of 135 strains of M canis, composed of 1R4 from the patients and 1 from an infected pet cat, were crossed with the 2 tester strains of eVannizzia otae VUT 77054 "/" and VUT 77055 "-" supplied by Dr. A. Hasegawa. These 134 human strains were originated from 77 casea of tinea capitis, 20 of tinea faciei and 37 of tinea corporis from Taegu city, Kyungpook and neighboring provinces during the period from December 1975 to August 1982. Out of 134 hurnan isolates, 112 (83. 6%) were of "-" mating type of N. otae and 22 (16.4%) were nonreactive. None were compatible with the + mating type. One strain from a pet cat proved also to be of type. The majority of the tested strains were revealed to be sexually degenerated.

The number of patients with tinea corporis diagnosed on the clinical findings and KOH examination was 1,709 during the five yea.rs between January 1976 and December 1980, representing l.5% of the total dermatologic out-patients of 105,267 examined at Chilgok Catholic Dermatological Clinic, Daegu, Korea. The annual number of patients with tinea corporis was 84 (0.47% of the total outpatients) in 1976,115 (0.6%) in 1977, and 263 (1.30%) in 1980, but the figure increased markedly in 1976 reaching 616 (2.51%) and 631 (2.89%) in 1980. Of the 1,709 patients, males numbered 793 and females 916. Although the age of peak incidence was in the third decade in both sexes, males outnumbered females slightly before age 19 and, as age advanced, female predominance became marked. The seasonal distribution of patients was interesting: in summer between June and September when the climate is very humid and hot, the incidence was markedly high. From the 1, 709 patients, 1,293 organisms composms of 6 species were isolated and identified. The species isolated were, in order of decreasing frequency, Trichophyton rubrum (622 organisms, 48. 1% of total organisms isolated), T. mentagrophytes (486 organisms, 36. 2%), Microsporum canis (147 organisms, 11. 4%), Epidermophyton floccosurn (29 organisms, 2.2%), M. gypseum (23 organisrns, l.8%) and T. ferrugineum (4 organisms, 0. 3%).

This study was designed to determine if topical cardiac hypothermia is a necessary adjunct to intraoperative myocardial protection. In this study, 105 patients ranging in age from 22 to 74 years were included. Myocardial temperature was measured at the ventricular septum. All patients received cold blood cardioplegia without topical cooling. In most of the patients(90%) the myocardial temperature was dropped to 10-15degrees C without topical cooling. In Group A, myocardial temperature was dropped rapidly to 10-15degrees C with, 1,000ml or less cardioplegic solution. In Group B, the amount of cardioplegic solution required for lowering myocardial temperature to 10-15degrees C was 1,000-2,000ml. In Group C, myocardial temperature was not dropped below 18degrees C or cardioplegic solution over 2,000ml was required for lowering myocardial temperatur. Eight patients(8/61, 8%) in group A, 12 patients(12/35, 34%) in group B and 8 patients(8/9. 89%) in group C had Complete obstructive lesions in at least one of major branches of coronary artery(p=0.001). Myocardial perfusion score was different among the groups(8.27+/-2.27 in group A, 9.98+/-2.21 in group B, 10.30+/-2.49 in group C, p<0.002). These data suggest that routine topical hypothermia may be unnecessary if myocardial temperature of less than 15degrees C could be attained with cold blood cardioplegia, especially in case of myocardial perfusion score below 10.

The coronary artery fistula from right coronary artery to left ventricle is a rare disease among coronary artery anomaly. We experienced three cases of rare coronary fistula and report with literature review. Although symptoms of coronary artery fistula are associated with arteriovenous shunt and coronary steal phenomenon, many cases are asymptomatic. In this report, all patients had no symptom. but incidental murmur was noted (two are continuous, one is diastolic rumbling). The diagnosis was made by transthoracic or transesophageal echocardiogram and selective coronary angiography. Because patients were relatively young and the diameter of dilated coronary artery were huge, we perfomed operation on three patients.

PURPOSE: Although influenza is regarded as one of the major causes of morbidity and mortality in children with cancer, the actual vaccine coverage remains poor. We conducted evaluation of immunogenicity and safety of influenza vaccine in children with cancer. METHODS: In this study, 25 children with cancer who received influenza vaccine (SK influenza IX vaccine(R)) at the Korea Cancer Center Hospital between October and December 2009 were analyzed. Blood samples of patients were collected twice (at the beginning of this study and at 30th day after vaccination) and their antibody titers were measured using the hemagglutination-inhibition (HI) assay. Immunogenicity of the influenza vaccine was assessed by seroprotection rate on days 0 and 30, seroconversion rate on day 30, and mean fold increase (MFI) of geometric mean titer (GMT) of HI between days 0 and 30. RESULTS: Any of the subjects in our study did not experienced serious adverse events after influenza vaccination. Seroprotection rates were 68% for H1N1, 40% for H3N2, and 36% for B. Seroconversion rates were 12% for H1N1, 16% for H3N2, and 20% for B. MFIs were 0.9 for H1N1, 1.2 for H3N2, and 1.8 for B. CONCLUSION: In the study, we found a limited protective immune response to influenza vaccine, among subjects with cancer. However, some subjects showed seroconversion, and there were no severe adverse events among all subjects, supporting the recommendation of annual influenza vaccination in children with cancer.

BACKGROUND: To compare flexible ring with rigid ring for annular remodeling and hemodynamic changes of left ventricle (LV) in mitral valve repair (MVR) at short term interval. METHODS: From January 1998 to March 2001, 35 patients with mitral valve prolapse underwent mitral valve repair with ring annuloplasty. The mean age of these patients was 49 years. Eighteen patients underwent mitral annuloplasty with Carpentier-Edwards Classic-ring (Group A). Seventeen patients underwent mitral annuloplasty with Physio-ring (Group B). LV fun-ction and annulus size were assessed by echocardiography on the day before operation and 2 to 3 months later. Mitral annular motion had been examined by means of the extent of mitral annular systolic excursion (MASE) as measured in two longitudinal LV segments (septal and lateral). RESULTS: 1) In valve pathology, anterior leaflet lesion was 14 cases, posterior was 14, combined lesion was 7 cases. 2) At all, left ventricular end-systolic dimension, left ventricular end-diastolic dimension and LV mass decreased postoperatively. But, no differences existed between the groups. 3) Postoperatively (after 2-3 months), echocardiograms in 35 patients demonstrated no mitral regurgitation (MR) in 16 cases, trace to mild MR in 17 cases, moderate MR in 2 patients. In Classic-ring group, MR was demostrated in 11 cases (61%). In Physio-group, MR was demonstrated in 8 cases (47%). 4) Postoperatively, mitral valve area increased significantly only in patients with Physio-ring (1.93+/-0.33 vs 2.38+/-0.92, p<0.05). 5) No differences existed between the groups in MASE. CONCLUSION: There are the significant reduc-tion in cardiac chambers and annulus size and improvement of LV function after both types of ring annuloplasty at short term result. There are no significant differences between Classic-ring and Physio-ring except 2 cases postrepair SAM (systolic anterior motion) of mitral valve in Classic-ring.

BACKGROUND: It has been demonstrated that ischemic preconditioning(IP, repetitive brief period of ischemia and reperfusion) enhances recovery of post-ischemic contractile dysfunction and reduces incidences of reperfusion-arrhythmia and infarct size after a prolonged ischemia. A lot of mechanisms have been proposed, however, controversies still remain. Recent studies suggested that IP could activate protein kinase C(PKC). Therefore, we measured left ventricular function, myocardial creatinin and PKC activities, and infarct size to assess whether IPs cardioprotective effect is related to PKC activation using isolated rabbit hearts. METHODS AND RESULTS: Hearts isolated from New Zealand White rabbits(1.5-2.0kg body weight) were perfused with Tyrode solution by Langendorff technique. After stabilization of baseline hemodynamics, the hearts were subjected to 60-min ischemia followed by 120-min reperfusion with IP(IP group, n=15) or without IP(control group, n=14), IP was induced by 4 cycles of 5-min global ischemia and 5-min reperfusion. Left ventricular function including developed pressure(LVEDP), dp/dt, heart rate(HR), and coronary flow(CF) was measured to determine the recovery of LVEDP, RPP(rate-pressure product, HRXLVEDP) and CF to baseline measurement. Frequency of arrhythmia was counted on reperfusion. Myocardial CK-MB, myocardial cytosolic and membrance PKC were measured and the infarct size was determined by staining with tetrazolium salt and planimetry. Data were analyzed by one-way ANOVA, Tukey's post-hoc test and t-test. There was no significant differences in the recovery of LVEDP, dp/dt, RPP, and CF and frequency of arrhythmia during reperfusion between the control and the IP groups. In comparison with the control groups, however, CK-MB was significantly lowered in the IP group(P < 0.05). Cytosolic PKC was significantly decreased but membrance PKC was increased(p < 0.05). These findings indicate that PKC was translocated and activated by IP. Furthermore infarct size was smaller and limited to the antero-lateral or posterior wall and papillary muscle in the IP group(p < 0.05). CONCLUSION: These results indicate that IP dose not improve post-ischemic contractile dysfunction after a prolonged ischemia of 60 minutes but has an infarct-limiting effect. This cardioprotective effect of IP may be related to PKC activation.
