We have experienced a case of pleural aspergillosis. A 50 year old female complained of malaise, anorexia, coughing with sputum, and right sided pleuritic chest pain of two weeks' duration. About ten years ago, she had been treated for pulmonary tuberculosis with medication. Chest radiography showed right pyopneumothorax with cavitation in the right upper lung and Chest computed tomography revealed right loculated pyopneumothorax with cavity formation suggesting bronchopleural fistula. Decortication and wedge resection with pleurectomy were performed. The postoperative course was satisfactory and has been in good condition up to now. Pleural aspergillosis is a very rare and potentially life-threatening disease, but we have had good results without significant complications by treatment with systemic antifungal drugs and surgical operation.

BACKGROUND: The aim of the current study was to analyze the early and intermediate-term performance of aortic valve replacement. MATERIAL AND METHOD: Between January 1986 and January 1996, records of 61 consecutive patients who had received aortic valve replacement were reviewed. 38 were male and 23 were female patients, ranging from 10 to 71 years of age (mean: 40.5+/-11.2). RESULTS: The early death rate was 4.9% (3/61). A thorough follow-up rate of 93.1% was accomplished in these 58 patients who left the hospital (mean: 51.5+/-32.0 patient-months) under the assistance of the same operator. Three of these patients who left the hospital died. The late death rate was 5.2% (3/58). Five patients experienced anticoagulant-related hemorrhage (all were minor). Three patients had thromboembolic episodes. There was no clinical evidence of hemolysis and structural failure of valves used. Of those patients who survived, the NYHA functional class improved significantly. Linearized rate were 1.58%/patient-year and 2.0%/patient-year respectively for thromboembolism and anticoagulant-related hemorrhage. The 10 year actuarial survival rate was 83.6%. CONCLUSION: This early and intermediate-term follow-up suggests that the mechanical valve is a reliable and durable prosthesis with good hemodynamic function and low rate of prosthesis-related complication.

Tailoring thoracoplasty is employed prior to, following, or concomitant with pulmonary resection when it is anticipated that insufHclent lung tissue will remain to fill the pleural space following a pulmonary resection. This study reviewed a series of eight patients treated with tailoring thoracoplasty between 1990 and 1995. Indications were to close a persistent space In four patients and to tailor the thoracic cavity to accept diminished lung volume concomitant with a pulmonary resection in the other four patients. The primary underlying disease was lung cancer in three patients and pulmonary tuberculosis In five patients, two of whom had concomitant aspcrgilloma, two, pneumothora, and one, empyema with bronchopleural fistula. In four patients with a prior pulmonary resection, the tailoring thoracoplasty was performed within eight days after the resection surgery. There was no failure to accommodate the thoracic cavity to insufficient lung tissue, even though two patients needed a second thoracoplasty. We conclude that tailoring thoracoplasty may be performed to close anticipated persistent pleural space and to accommodate diminished lung volume with acceptable cosmetic results Early, after, or concomitant with pulmonary resection in selected patients.

OBJECTIVE: The aim of this study was to determine whether fetuses delivered prematurely because of pregnancy complications had a different neonatal outcomes than that of those bom after either spontaneous preterm labor or after premature rupture of membrane. METHODS: The study design was a retrospective analysis of 150 very low birthweight(<1500 grams) infants and their mothers who delivered preterm neonates at Samsung Medical Center. Only singleton infants without major congenital anomalies were included. The primary reason for delivery was categorized as preterm delivery because of pregnancy complications(indicated preterm delivery) or spontaneous preterm delivery. Selected neonatal outcomes were compared between infants born to women in each of these groups. RESULTS: There were some survival benefits in infants born to women who underwent indicated preterm delivery from univariate analyses. In the multiple logistic regression analysis, however, selected neonatal outcomes did not differ between the groups. CONCLUSION: We concluded that a "stressed" pregnancies confer negligible survival advantage to the very low birthweight infants.

BACKGROUND: Although arterial grafts are widely used due to the advantage of long-term patency in coronary bypass surgery, greater saphenous vein is still an important additional conduit. It was reported that preservation of the adventitia of vein graft and the adjacent tissues may bring the improved long-term graft patency. The aim of this study is to look for a harvest technique that can reduce vein injury and wound complications. MATERIAL AND METHOD: In thirty-four patients that vein grafts were used for coronary bypass surgery, 50 harvest sites were included for the study. In 25 harvest sites in calf below knee (group 1), vein was exposed through a long incision and then clearly dissected from the adjacent tissue. Ten endoscopic vein harvests were performed in the thighs (group 2). Fifteen other vein grafts that were bluntly dissected were harvested from the thighs through three separate incisions (group 3). RESULT: Vein harvest time was longest in endoscopic harvest group (44.7+/-9.8 minutes) and shortest in group 3 (24.2+/-5.9 minutes) (p=0.000). Most avulsion injuries of vein branches happened in the endoscopic group. Sequential grafting numbers per vein were 1.72+/-0.98 with thigh vein graft and 1.16+/-0.37 with calf vein (p=0.02). Swelling of foot and/or leg, which was the most common wound complication after vein harvest, was most commonly presented in group 1 (20/25 sites; p=0.000). Tingling, the most common neurologic complication, was also most prevalent in group 1 (7/25 sites; p=0.013). The risk factor of the wound complication was vein harvest from calf, and the vein harvest technique was not a risk for wound complication. CONCLUSION: Vein harvest technique through three separate incisions from thigh presented shorter harvest time and less vein injury and wound complication compared with the endoscopic harvest technique from thigh or the harvest through a long incision from calf.

PURPOSE: This study was designed to review the results of 2nd and 3rd kidney transplantation at our center. METHODS: Total 1,500 patients who had undergone kidney transplantation from 1968 to Aug 2005 at the Catholic Medical Center were retrospectively analyzed. The graft and patient survival were determined using Kaplan-Meier actuarial survival curves, compared with those of first transplant and assessed for significance using the log rank test. RESULTS: The patient of 2nd transplantation was 77 cases (male 55, female 22, mean age: 48.9+/-2.4 years) and 3rd transplantation was 5 patients (male 4, female 1, mean age 46.8+/-6.0 years). The 82 kidneys included from living donors in 67 patients and from cadaveric donors in 15 patients. The most common cause of renal failure of retransplanted kidney was chronic GN (2nd: 62 cases (80.5%), 3rd: 5 cases (100%)). The immunosuppressive regimen was mainly based on cyclosporine (2nd: 61 cases (79.2%), 3rd: 3 cases (60%)). The mean duration of the second transplantation from the first was 89.0 months and the third transplantation from the second was 32.7 months. There were 16 cases of death patients and the main cause of death was infection and cardiovascular events. The graft survival of 2nd & 3rd transplantation in 1 year were over 80%. CONCLUSION: Renal retransplantation is safe, effective, and the treatment of choice in patients with failed previous kidney transplantation for patient's quality of life and not associated with increased mortality retransplantation. The results of graft survival for retransplantation seem to be excellent for primary transplantation under cyclosporine or tacrolimus-based immunosuppression. The use of the potent and appropriate immunosuppression and surgical technique for retransplantation could help to improve better results.

Aldosterone has been shown to stimulate renal TGF-beta1 expression. However, the mechanisms for aldosterone-induced TGF-beta1 expression have not been clearly determined in mesangial cells. We examined the role of extracellular-signal regulated kinase 1 and 2 (ERK1/2), c-Jun N-terminal kinase (JNK) and activator protein- 1 (AP-1) in the aldosterone-induced TGF-beta1 expression in rat mesangial cells. TGF-beta1 protein in the conditioned medium released from rat mesangial cells was measured by sandwich ELISA, TGF-beta1 mRNA expression was analyzed by Northern blotting, AP-1 DNA binding activity was measured by EMSA and the ERK1/2, JNK activity was analyzed by western blotting. Aldosterone significantly stimulated TGF-beta1 protein production and TGF-beta1 mRNA expression in mesangial cells in a dose-dependent manner. Aldosterone significantly increased AP-1 DNA binding activity in mesangial cells. Pre-treatment of cells with AP-1 inhibitor, curcumin, blocked aldosterone-induced AP-1 DNA binding activity as well as aldosterone-induced TGF-beta1 production. Aldosterone increased phosphorylation of ERK1/2 and JNK in mesangial cells. Pre-treatment of cells with ERK1/2 inhibitor, PD98059, or JNK inhibitor, SP600125 significantly inhibited aldosterone-induced ERK1/2 and JNK activity and subsequently TGF-beta1 production, respectively. We conclude that aldosteroneinduced TGF-beta1 expression in mesangial cells is regulated by the ERK1/ 2, JNK and AP-1 intracellular signaling pathways.

PURPOSE: The importance of postoperative management of those who have undergone intracardiac repair for congenital heart diseases has increased in recent years. In this study, we investigated postoperative complications and their relations to preoperative age or duration of the intubation and artificial ventilation in infants with large symptomatic ventricular septal defect. METHODS: Between January, 1993 and December, 1996, sixty infants underwent primary closure of a ventricular septal defect (VSD). The patients were divided into two groups based on preoperative age : group 1, infants aged 6 month or less (n=40), and group 2, infants aged more than 6 month (n=20). And, another three groups were divided into 3 groups due to the duration of the intubation and artificial ventilation including < 24 hour and 24-48 hour, >48 hour, respectively. We compared the incidence of complications such as infection, respiratory or cardiovascular complications among each group. RESULTS: No specific differences between two age groups were found, but the incidence of right bundle branch block was high in age group of 6 month or less (P<0.05). The incidence of sepsis was high in group of >48 hour (P<0.05). And also, arrhythmias, atelectasis, toxic hepatitis were more frequently observed in the former group. CONCLUSION: These results indicate that early weaning of the artificial ventilation in infants with large symptomatic ventricular septal defect could protect them from development of severe life- threatening infection such as sepsis. We suggest 48 hours or less as the optimal duration of artificial ventilation. Additionally, earlier weaning could provide earlier oral feeding or earlier ambulation, which is improve respiratory homeostasis.

BACKGROUND: The HLA system is known to be the most polymorphic gene cluster in the human genome. HLA allele and haplotype distribution varies widely among different ethnic groups. In this study, we examined the frequency of HLA class I alleles and haplotypes in 309 healthy Koreans. METHODS: We typed HLA-A, -B, and -C genes at the allelic level in 109 unrelated Korean individuals using a sequence-based typing. With the additional data of 200 healthy Koreans from dbMHC (http: //www.ncbi.nlm.nih.gov/mhc/), allele and haplotype frequencies were estimated by the maximum likelihood method. Serological typing results of 49 individuals were compared with the results highly resolved. RESULTS: A total of 22 HLA-A, 41 HLA-B, and 21 HLA-C alleles were found in this study. Alleles showing frequencies of more than 10% in each HLA locus were A*2402 (22.5%), A*0201 (15.7%), A*3303 (14.4%), A*1101 (11.0%), B*5101 (12.1%), Cw*0102 (18.8%), and Cw*1402 (10.2%). The most common A-B-C haplotypes at a frequency of more than 3% were A*3303-B*5801-Cw*0302 (5.2%), A*2402-B*5101-Cw*1402 (4.5%), A*1101-B*1501-Cw*0401 (4.3%), A*3303-B*4403-Cw*1403 (4.0%), A*3001-B*1302-Cw*0602 (3.7%), and A*0207-B*4601-Cw*0102 (3.2%). Misassignment of HLA-C antigen by serotyping was detected in 11 (22.4%) of 49 individuals. CONCLUSIONS: Our results will be useful as a basic data for studies on anthropology, disease association, and bone marrow transplantation. Misidentification of HLA-C by serotyping is so high that it would be desirable to perform a DNA typing especially in unrelated bone marrow transplantation.

We experienced a case of partial anomalous pulmonary venous return from righ lung to inferior vena cava, which combined with Scimitar sign in 18 years old female patient. Diagnostic procedures were simple chest x-ray chest CT, and cardiac catheterization. We redirected the anomalous venous flow from inferior vena cava to left atrium through the intracardiac tunnel which was made with autologous pericardium. Postoperative course was not eventful.
