Wegener's granulomatosis is a disease with an unknown etiology that is characterized by necrotizing granulomatous vasculitis involving the upper and lower respiratory tract and the kidneys. The typical pulmonary findings are bilaterally involved multiple variable sized nodules. We report a case of Wegener's granulomatosis that presented as a single lung mass. A male patient presented with a nasal obstruction, arthralgia, cough, and intermittent dyspnea. The chest radiograph showed a mass, approximately 4.5 cm in diameter, in the right lower lobe. Lung cancer or tuberculosis was initially considered. However, the clinical, laboratory and pathological findings of the mass indicated Wegener's granulomatosis. The patient was administered prednisolone and cyclophosphamide, and improved temporarily. Unfortunately, the immunocompromised patient expired as a result of respiratory failure with pneumonia.
From 1983, until June, 1990, 10 patients with various type of truncus arteriosus underwent total surgical correction including Rastelli procedure at Seoul National University Hospital. The age at operation ranged from 1 month to 9 years [mean 2.1 years]. Six patients had truncus type I, 3 patients had truncus type II, and one patients had truncus type IIIc. Right ventricular pulmonary artery continuity was established with a porcine valved conduit in 6 patients, mechanical valved conduit in 1 patient, and bovine pericardial conduit in 3 patients. The postoperative right ventricular /left ventricular pressure ratio ranged from 0.4 to 0.71 [mean 0.51${\pm}$0.14]. The lung histology revealed grade II pulmonary obstructive disease even at 4 month of age. Five patients were dead in hospital [50%], and they were less than 2 year of age. One patient, who had severs congestive heart failure preoperatively, died of low output syndrome and the other died of low output syndrome with postoperative bleeding. There were three death, because of a pulmonary hypertensive crisis that might have been prevented. Two of the five survivors had conduit failure over a mean follow up of 42 months [range 1 to 78 months]. Obstructed conduit was removed and a new conduit constructed using the conduit bed as the posterior wall and the patch of bovine pericardium and Dacron as patch the roof of the conduit. One patient died of acute cardiac failure during the operation. Although results in infants less than 2 years old have not been good, current improvement of intra-and postoperative care suggested that prompt repair is indicated for infants with truncus arteriosus.
We report a case of pneumonia in 36 year-old male patient who presented acute respiratory failure and associated radiologic findings of bilateral ground-glass opacity with focal cystic changes, showing rapidly aggravating course and was diagnosed as concomitant Pneumocystis carinii and Cytomegalovirus pneumonia accompanied by acquired immunodeficiency syndrome through antemortem open lung biopsy.
The 242 patients were operated due to chronic empyema in Hanyang University Hospital From Jan, 1983 to Aug, 1991, we operated 17 patients by modified.Schede`s thoracoplasty with myoplasty and we concluded to next scentences. 1. The age of patients were varied from 28 to 65[Average 39.1] and male preponderance was seen[more than 3 times]. 2. The preoperative cause of disease were tuberculosis in 14 patients[3 patients were associated with aspergillosis, and 1 patient was associated vrith actinomycosis], lung abscess in 2 patients, and haemophilia in 1 patient. 3. The Preoperative duration of empyema were varied from 1 month to 30 years[Average 49.8 month], and the duration from pulmonary resection to thoracoplasty were 1 month to 13.5 years[Average 55 month] except 3 patients, who were operated pneunectomy with thoracoplasty at the same time. 4. The total number of thoracoplasty were 19, because in 2 patients, we operated 2 steps, and we failed in 6 cases, so the success rate was 68.5%. 5. In failure analysis of 6 cases, the cause were obliteration failure in 3 cases, inadequete drainage in 1 case, and in the other 1 case was mixed type. 6. From 1990 to 1991, there were no death associated with operation and there were 1 failure, so the success rate was greatly improved. 7. The bronchopleural fistula or spontaneous rupture of trachea were seen in 12 cases, and the success rate was high in absent cases.

Background: Tracheostomy is a common procedure for patients requiring prolonged mechanical ventilation. However, the timing of tracheostomy is quite variable. This study was performed to find out the factors determining the timing of tracheostomy in medical intensive care unit (ICU). Methods: Patients who were underwent tracheostomy between January 2008 and December 2009 in the medical ICU of Seoul National University Hospital were included in this retrospective study. Results: Among the 59 patients, 36 (61.0%) were male. Median Acute Physiology And Chronic Health Evaluation (APACHE) II scores and Sequential Organ Failure Assessment scores on the admission day were 28 and 7, respectively. The decision of tracheostomy was made on 13 days, and tracheostomy was performed on 15 days after endotracheal intubation. Of the 59 patients, 21 patients received tracheostomy before 2 weeks (group I) and 38 were underwent after 2 weeks (group II). In univariate analysis, days until the decision to perform tracheostomy (8 vs. 14.5, p<0.001), days before tracheostomy (10 vs. 18, p<0.001), time delay for tracheostomy (2.1 vs. 3.0, p<0.001), cardiopulmonary resuscitation (19.0% vs. 2.6%, p=0.049), existence of neurologic problem (38.1% vs. 7.9%, p=0.042), APACHE II scores (24 vs. 30, p=0.002), and $PaO_2/FiO_2$ <300 mm Hg (61.9% vs. 91.1%, p=0.011) were different between the two groups. In multivariate analysis, APACHE II scores${\geq}20$ (odds ratio [OR], 12.44; 95% confidence interval [CI], 1.14~136.19; p=0.039) and time delay for tracheostomy (OR, 1.97; 95% CI, 1.11~3.55; p=0.020) were significantly associated with tracheostomy after 2 weeks. Conclusion: APACHE II scores${\geq}20$ and time delay for tracheostomy were associated with tracheostomy after 2 weeks.
Cystic lesions or progressive cystic changes in adenocarcinoma of the lung have rarely been reported. We report a case of lung adenocarcinoma that progressed from ground-glass opacities (GGOs) and consolidations or nodules to extensive cystic lesions during 12 months in a young adult patient. A 29-year-old male was initially diagnosed with primary lung adenocarcinoma by transbronchial lung biopsy of the right lower lobe and lung to lung metastasis in both lungs according to imaging findings. The initial chest computed tomography (CT) scans showed multifocal GGOs, consolidations, and nodules in both lungs. Despite treatment with palliative chemotherapy, the patient's follow-up CT scans showed multiple, cystic changes in both lungs and that the lesions had progressed more extensively. He died of hypoxic respiratory failure one year after his diagnosis.

To evaluate the possible therapeutic effects of growth hormone and vitamin C on multiorgan failure, a rat model was developed for LPS-induced sepsis. Using this model, the effects of growth hormone and vitamin C on tissue damages, catalase and i-NOS activities, and MDA levels were examined in the lung and liver. The level of TNF- in plasm was also examined. Male, Sprague-Dawley rats were injected with LPS intraperitoneally then divided into 3 groups : positive controls injected with LPS only, the ones injected with growth hormone or vitamin C immediately after the LPS injections. The lung and the liver were then isolated, blood samples were collected at 24 or 48 hours after the LPS injection, then examined for histopathological and biochemical changes. The results obtained were as follows. 1. LPS induced sinusoid vasodilation and mild destruction of lobular structure in the liver. In the lung, alveolar structure appeared to be thickened and interstitial edema was observed. The levels of MDA in the liver and the lung was increased by LPS, while the activity of catalase was decreased. The activity of i-NOS of those tissues was also increased, which was more pronounced at 24 hr. The level of TNF- in plasm was increased by LPS 2. In the lung, vitamin C suppressed lymphocyte and neutrophil infiltration, alveolar wall thickening and interstitial edema. In the liver, vitamin C protected against the destruction of the lobular structure. The activity of catalase reduced by LPS was reversed partly by vitamin C. The activity of i-NOS enhanced by LPS was also reversed by vitamin C. The level of TNF- in plasm reduced in some animals by vitamin C, which however was not significant statistically(p<0.05). 3. Growth hormone showed similar protective effects against inflammation and damages in the liver and lung tissues. Growth hormone reversed partly the LPS effects on the level of MDA, the activity of catalase and i-NOS induction in the liver and the lung. Growth hormone reduced plasma level of TNF-${\alpha}$ substantially, which contrasted from vitamin C. Besides this, overall protective effects of growth hormone against LPS-induced experimental sepsis were similar to those of vitamin C. From this results, the mechanism of growth hormone on suppression of LPS-induced tissue damage might be associated with production of antioxidative enzyme and suppression of plasma TNF- level.
From Jan.1982 to Dec.1990, 77 patients with rectal cancer were treated with curative surgical resection followed by postoperative adjuvant irradiation alone or combined with chemotherapy at the Department of Radiation Oncology, Korea University Hospital (KUH). Fifty-four (54/77, $70.1{\%}$) patients underwent abdominoperineal resection , 20 (20/77, $26{\%}$) patients underwent low anterior resection, and 3 (3/77, $3.9{\%}$,) patients had wide excision only. Thirty-nine (39/77, $50.5{\%}$) received sequential chemotherapy (2 cycles to 12 cycles). The 5-year survival rate for the entire group was $43{\%}:\;78.2{\%}$ in B2+B3, $39.4{\%}$ in stage C1+C2+C3. Survival rates decreased with increasing penetration of the bowel wall by tumor and the presence of regional lymph node metastasis. Those patients survival who underwent an abdominoperineal resection also experienced a significant decrease in compared to low anterior resection ($23.1{\%}$ vs. $63.8{\%}$ in 5-year survival, p <0.05). Local failure occurred in 15 ($19.5{\%}$) out of the 77 patients overall, 1($5.3{\%}$) of 19 in stage B2+B3, and 14 ($24.1{\%}$,) of 58 in stage C1+C2+C3. Presacral area was most common site of local failufre (8/17, $47.1{\%}$). Distant failure occurred in 13 ($16.9{\%}$) of 77 patients. The most frequent site of distant failure was the lung followed by the liver, the bone, and the brain. Combined locoregional and distant failure occurred in 2 ($2.6{\%}$) of 77 patients. Pathological confirmation of perirectal fat and/or regional lymph node involvement resulted in a singificant decrease in survival and local control.

Purpose: To explore the role of salvage radiotherapy (RT) for recurrent thymoma as an alternative to surgery. Materials and Methods: Between 2007 and 2015, 47 patients who received salvage RT for recurrent thymoma at Yonsei Cancer Center were included in this study. Recurrent sites included initial tumor bed (n = 4), pleura (n = 19), lung parenchyma (n = 10), distant (n = 9), and multiple regions (n = 5). Three-dimensional conformal and intensity-modulated RT were used in 29 and 18 patients, respectively. Median prescribed dose to gross tumor was 52 Gy (range, 30 to 70 Gy), with equivalent doses in 2-Gy fractions (EQD2). We investigated overall survival (OS), progression-free survival (PFS), and patterns of failure. Local failure after salvage RT was defined as recurrence at the target volume receiving >50% of the prescription dose. Results: Median follow-up time was 83 months (range, 8 to 299 months). Five-year OS and PFS were 70% and 22%, respectively. The overall response rate was 97.9%; complete response, 34%; partial response, 44.7%; and stable disease, 19.1%. In multivariate analysis, histologic type and salvage RT dose (≥52 Gy, EQD2) were significantly associated with OS. The high dose group (≥52 Gy, EQD2) had significantly better outcomes than the low dose group (5-year OS: 80% vs. 59%, p = 0.046; 5-year PFS: 30% vs. 14%, p=0.002). Treatment failure occurred in 34 patients; out-of-field failure was dominant (intra-thoracic recurrence 35.3%; extrathoracic recurrence 11.8%), while local failure rate was 5.8%. Conclusion: Salvage RT for recurrent thymoma using high doses and advanced precision techniques produced favorable outcomes, providing evidence that recurrent thymoma is radiosensitive.

From 1979 to 1982, 80 patients with unresectable non-small-cell lung cancer without metastasis were treated with high-dose radiotherapy to the primary and to regional lymph nodes with or without supraclavicular lymphatics in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 56 patients$(70\%)$ were completely evaluable, and 59 patients$(74\%)$ had squamous cell carcinoma, 13a large cell undifferentiated carcinoma and 831 adenocarcinoma. 21 patients$(26\%)$ had Stage II and 59 patients$(74\%)$ had Stage III. The complete and partial response rate in the high-dose$(\approx\;6,000\;rad)$ radiotherapy was $70\%\;with\;19\%$ complete response. 69 patients$(86\%)$ failed in the treatment, by the failure pattern, $64\%$ had local failure alone, $35\%$ had local failure and distant metastasis and $1\%$ had distant metastasis alone. The failure rate in the thorax were $76\%$ in squamous cell carcinoma, $40\%$in adenocarcinoma and $20\%$ in large cell undifferentiated carcinoma Preliminary result shows that actuarial survival at 1, 2 and 3 years were $56\%,\;26\%\;and\;20\%$ in overall patients and $64\%,\;37\%\;and\;21\%\;in\;Stage\;II\;and\;54\%1,\;21\%\;and\;18\%$ in Stage III, respectively. Overall median survival was 14 months; 17 months in Stage II and 13 months in Stage m. 8 patients$(10\%)$ have lived a minimum of 2 years with no evidence of disease. There was no fatal complication confirmed to be induced by radiotherapy, so definitive high-dose radiotherapy was tolerated well without major problems and resulted in good local control and survival.
