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.

Hyperhidrosis of the palms, axillae, and the face has a strong negative impact on the quality of life for many people. Existing nonsurgical therapeutic options are far from ideal. A definitive cure can be obtained by upper thoracic sympathectomy. The traditional open surgical technique is a major procedure; few patients and doctors have found that risk-benefit considerations favor surgery. Endoscopic minimal invasive surgical techniques are now available. We investigated whether endoscopic ablation of upper thoracic sympathetic chain (T2-4) is an efficient and safe treatment of hyperhidrosis. We treated 40 patients with bilateral endoscopic transthoracic sympathectomy. There were no mortalities, life-threatening complication, no treatment failures occurred in 40 patients. After a short-term follow-up, 100% of the patients reported satisfactory results. Endoscopic transthoracic sympathectomy is an efficient, safe, and minimally invasive surgical method for the treatment of palmar, axillary hyperhidrosis.

For the management of a secondary spontaneous pneumothorax, videothoracoscopic surgery may offer the potential therapeutic benefits of a minimally invasive approach. We report on a series of 36 patients (33 men and 3 women) with a mean age of 56.3 years (range, 31 to 80 years) who underwent thoracoscopic surgical procedures for the treatment of secondary spontaneous pneumothorax. Twenty-one patients had emphysema and 20 patients had old pulmonary tuberculosis. Nineteen patients presented a persistent severe air leak more than 3 days preoperatively and 15 patients had more than one recurrence. Bullectomy or exclusion of the lesion was performed in 33 patients. Mechanical pleurodesis was performed in the entire patients, talc was sprayed in 22 and vibramycin in 14. Mild pleural adhesion at the upper lobe was shown in 10 patients and severe pleural adhesion in 7 patients. One patient with persistent air leak died of persistent air leak and respiratory failure. The mean postoperative stay was 7.0 days (range, 2 to 17 days). At a mean follow-up of 15.8 months (range, 5 to 45 months), no pneumothorax had recurred. In comparison with the result of the treatment for 112 patients with primary spontaneous pneumothorax, the operating time was not significantly longer and there were no more primary treatment failures, but the duration of postoperative chest drainage and hospital stay was longer. Videothoracoscopic surgery has proved to be an effective treatment for secondary spontaneous pneumothorax in elderly patients who represent high-risk candidates for thoracotomy.

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.

The bone scan in patients with prostate cancer remains to be the most sensitive method to assess the bone metastasis. But it is nonspecific and shows similar finding in either benign or malignant disease. Bone mineral densitometry allows for the quantification of total body bone mass. So we evaluated the efficacy of the measurement of the bone mineral density with dual-energy X-ray absorptiometry in patients with prostate cancer who had showed hot spot on the bone scan. Of the 15 patients 7 cases( 47% ) showed increased bone mineral density. To evaluate the efficacy of bone mineral densitometry, we analyze the 11 patients whose bone scan show hot spot on lumbar spine. Among them 2 cases( 18%) show osteoblastic finding on the bone x-ray, but 5 cases(45%) show increased density and 2 cases show decreased density on the bone mineral densitometry. These results show that the bone mineral densitometry is more valuable than bone x-ray in the detection of abnormal bone density. Therefore we suggest that bone mineral densitometry can be used as a helpful method of bone scan to detect the metastatic bone lesion in the advanced prostatic cancer.

OBJECTIVE: To analyze the prognostic factors thought to be related with survival time after a spinal metastasis operation. METHODS: We retrospectively analyzed 217 patients who underwent spinal metastasis operations in our hospital from 2001 to 2009. Hematological malignancies, such as multiple myeloma and lymphoma, were excluded. The factors thought to be related with postoperative survival time were gender, age (below 55, above 56), primary tumor growth rate (slow, moderate, rapid group), spinal location (cervical, thoracic, and lumbo-sacral spine), the timing of radiation therapy (preoperative, postoperative, no radiation), operation type (decompressive laminectomy with or without posterior fixation, corpectomy with anterior fusion, corpectomy with posterior fixation), preoperative systemic condition (below 5 points, above 6 points classified by Tomita scoring), pre- and postoperative ambulatory function (ambulatory, non-ambulatory), number of spinal metastases (single, multiple), time to spinal metastasis from the primary cancer diagnosis (below 21 months, above 22 months), and postoperative complication. RESULTS: The study cohort mean age at the time of surgery was 55.5 years. The median survival time after spinal operation and spinal metastasis diagnosis were 6.0 and 9.0 months. In univariate analysis, factors such as gender, primary tumor growth rate, preoperative systemic condition, and preoperative and postoperative ambulatory status were shown to be related to postoperative survival. In multivariate analysis, statistically significant factors were preoperative systemic condition (p=0.048) and postoperative ambulatory status (p<0.001). The other factors had no statistical significance. CONCLUSION: The factors predictive for postoperative survival time should be considered in the surgery of spinal metastasis patients.

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.

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.

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.
