AbstractAbstract PDF
BACKGROUND
Recent studies have shown that the nontuberculosis mycobacterium (NTM) recovery rate in clinical cultures has increased within Korea. However, another study conducted by a secondary hospital within Daegu reported different results. Therefore, the purpose of this study is to understand and evaluate the microbiological distribution and clinical features of NTM in Daegu. METHODS: A retrospective study was conducted on 11,672 respiratory specimens undergoing acid fast bacilli (AFB) culture from 6,685 subjects who visited Yeungnam University Respiratory Center from January 2012 to December 2013. RESULTS: Of the 11,672 specimens undergoing AFB culture, 1,310 specimens (11.2%) showed positive results. Of these specimens, NTM was recovered from 587 specimens, showing a recovery rate of 44.8%. Identification test for NTM was performed on 191 subjects; the results were as follows: M. avium-intracellulare complex (MAC) 123 (64.4%), M. abscessus 20 (10.5%), M. kansasii 12 (6.3%), and 33 other NTM germ strains. Of the 382 subjects with NTM, 167 were diagnosed with pulmonary NTM disease (43.7%), however virulence differed depending on NTM strain. Multivariate analysis showed that nodular bronchiectasis, the nodules, and finding consistent with cavity under imaging study were statistically significant for triggering pulmonary NTM disease. AFB culture showing MAC and M. abscessus was statistically significant as well. Positive predictive value for NTM polymerase chain reaction (NTM-PCR) was 88.6%. CONCLUSION: Results for NTM recovery rate within the Daegu area were similar to those for the Seoul metropolitan area. We can assume that NTM infection is increasing in our community, therefore AFB-positive subjects (1) should undergo NTM-PCR, (2) should have their culture results checked for differentiation of mycobacterium tuberculosis complex (MTB) from NTM, and (3) undergo NTM identification test to confirm its type. Administration of treatment with the above results should be helpful in improving the patients' prognosis.

AbstractAbstract PDF
BACKGROUND
The optimal timing of treatment with EGFR-tyrosine kinase inhibitors (EGFR-TKI) in NSCLC patients has not yet been determined. METHODS: We separated 228 patients with advanced/metastatic NSCLC treated with gefitinib into an early gefitinib group (patients who received gefitinib as first- or second-line treatment) and a delayed gefitinib group (patients who received gefitinib as third or fourth-line treatment) and attempted to determine whether the timing of gefitinib treatment affected clinical outcomes. RESULTS: Median overall survival (OS), progression free survival (PFS), and median OS from first-line treatment of advanced/metastatic disease (OSt) for 111 patients in the early gefitinib group were 6.2 months, 3.3 months, and 11.6 months. However, median OS, PFS, and OSt for 84 patients in the delayed gefitinib group were 7.8 months, 2.3 months, and 22.7 months. No differences in OS and PFS were observed between the 2 groups. However, OSt was significantly longer in the delayed gefitnib group. Timing of gefitinib therapy was one of the independent predictors of OSt. Hb > or = 10 g/dl, and having never smoked, and ECOG performance status < or =1 were independent predictors of better PFS. CONCLUSION: Deferral of gefitinib therapy in patients with advanced or metastatic NSCLC may be preferable if they are able to tolerate chemotherapy.

AbstractAbstract PDF
A paragonimiasis infestation is caused by the paragonimus species. Paragonimiasis mainly occurs by ingestion of raw or undercooked freshwater crabs or crayfish. In our country, the prevalence of paragonimiasis was high until late 1960s due to eating habits, but after the 1970s the prevalence of the disease has markedly decreased and now the disease is rarely seen. The diagnosis of tuberculosis by Chest X-ray is often confused with pulmonary carcinoma, bacillary and parasitic infections, and chronic mycosis. Pulmonary paragonimiasis must be considered in the differential diagnosis of lung cancer especially in the appropriate clinical setting because effective treatment with praziquantel can be rewarding. We report a case of a 58-year-old woman with pulmonary paragonimiasis that was suspicious for lung cancer, as detected by biopsy.

AbstractAbstract PDF
Lymphangioleiomyomatosis (LAM) is a rare, cystic lung disease that is associated with mutation in the tuberous sclerosis genes, renal angiomyolipomas, lymphatic spread and a remarkable female gender predilection. The pathology of LAM is represented by the proliferation of immature smooth muscle cells in the walls of airways, and venules and lymphatic vessels in the lung. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax and collections of chylous fluid. The diagnosis of pulmonary LAM can be made on chest X-ray, a high-resolution CT scan and lung biopsy. We experienced a case of pulmonary lymphangioleiomyomatosis in a 28-years-old female patient who had suffered from progressive dyspnea on exertion, so we report on it along with a brief review of the relevant literature.

AbstractAbstract PDF
Pulmonary alveolar proteinosis (PAP) is a rare disorder that's characterized by accumulation of surfactant components in the alveolar space. Idiopathic PAP is recognized as an autoimmune disease that's due to impaired alveolar macrophage function and this caused by autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). We report here a case of pulmonary alveolar proteinosis that was deemed interstitial lung disease at the initial diagnosis. A 61-year-old man presented with intermittent blood tinged sputum and dyspnea on exertion. The man was a painter for 30 years and he had a 10 pack-years smoking history. Chest computerized tomography (CT) revealed multifocal ground-glass opacity with interstitial thickening at both lungs. His pulmonary function tests and methacholine test revealed non specific results. He was diagnosed with interstitial lung disease on the basis of the chest CT finding and occupational history. However, seven months later, his symptoms progressed. Follow-up chest CT was performed. Wedge resection via video-assisted thoracoscopic surgery (the anterior basal segment of the left lower lobe) was done. Microscopic examination showed large groups of alveoli with excessive amounts of surfactant and a complex mixture of protein and lipid (fat) molecules. Finally, he was diagnosed as having pulmonary alveolar proteinosis.

AbstractAbstract PDF
Eosinophilic myositis is a rare idiopathic inflammatory muscle disease, and the patients with this malady present with diverse signs and symptoms such as muscle swelling, tenderness, pain, weakness, cutaneous lesions and eosinophilia. The etiology and pathogenesis of eosinophilic myositis remain elusive. Several drugs may occasionally initiate an immune mediated inflammatory myopathy, including eosinophilic myositis. We report here on a case a 17-year-old female patient who had taken anti-tuberculosis medicine for tuberculosis pleurisy. She presented with many clinical manifestations, including fever, skin rash, proximal muscle weakness, dyspnea, dysphagia and hypereosinophilia. She was diagnosed with eosinophilic myositis by the pathologic study. The muscle weakness progressed despite of stopping the anti-tuberculosis medicine, but the myositis promptly improved following the administration of glucocorticoid. Although drug induced myopathies may be uncommon, if a patient presents with muscular symptoms, then physicians have to consider the possibility of drug induced myopathies.

AbstractAbstract PDF
Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects the medium-sized muscular arteries, with occasional involvement of the small muscular arteries. As with other vasculitides, PAN can affect any organ system, including the cardiovascular, gastrointestinal and central nervous systems. The prognosis for patients with untreated PAN is relatively poor, with five-year survival rates of approximately 13 percent. The outcome has improved with proper therapy to approximately 80 percent survival at five years. We report here on a case of a 46 year old man with polyarteritis nodosa and who suffered from pulmonary tuberculosis.

AbstractAbstract PDF
Pulmonary hypertension is an increase in blood pressure in the pulmonary artery, pulmonary vein or pulmonary capillaries. Depending on the cause, pulmonary hypertension can be a severe disease with markedly decreased exercise tolerance and right-sided heart failure. Pulmonary hypertension can present as one of five different types: arterial, venous, hypoxic, thromboembolic, or miscellaneous. Chronic obstructive pulmonary disease with severe pulmonary hypertension is a rare disease. A 52-year-old man presented with a complaint of aggravating dyspnea. The mean pulmonary arterial pressure was 61.5 mmHg by Doppler echocardiogram. The patient was prescribed diuretics, digoxin, bronchodilator, sildenafil, bosentan and an oxygen supply. However, he ultimately died of cor pulmonale. Thus, diagnosis and early combination therapy are important.

AbstractAbstract PDF
Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristic radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.

AbstractAbstract PDF
The tumor lysis syndrome has been described as biochemical disturbances associated with rapid destruction of tumor cells and subsequent synchronized massive release of cellular breakdown products sufficient to overwhelm excretory mechanisms and the body's normal reutilization capacity. The cardinal signs of the tumor lysis syndrome are hyperkalemia, hyperphosphatemia, hypocalcemia and hyperuricemia. Gefitinib (Iressa) is an oral, selective epidermal growth factor receptor (EGFR) inhibitor that has activity in female, non-smoker and non-small cell lung cancer with an EGFR mutation. Gefitinib is a well tolerated drug with few side effects. It has been associated with skin rash, diarrhea, nausea, a decrease in liver function and interstitial lung disease. However, there is no prior report of the tumor lysis syndrome associated with gefitinib. We report a case of a 54 year-old woman who developed tumor lysis syndrome that might have been induced by gefitinib after the treatment of adenocarcinoma of lung with an EGFR mutation.

AbstractAbstract PDF
BACKGROUND
Malignant pulmonary nodules account for about 30 to 40 percent of solitary pulmonary nodules (SPN). Therefore, tissue characterization of SPNs is very important. Recently, PET/CT has been widely used for tissue characterization, and has become of importance. The purpose of this study was to compare and to assess multiple factors in PET/CT comparing benign and malignant nodules. MATERIALS AND METHOD: Nineteen patients with SPN underwent PET/CT and biopsy. The difference of standardized uptake value 1 (SUV1), standardized uptake value 2 (SUV2) and retention index in PET/CT between malignancy and benignancy were compared by Levene's test. RESULT: There were twelve malignant and seven benign nodules. SUV1 and SUV2 were significantly different between malignant nodule and benign nodule (p=0.006 and 0.022), but retention index was not significantly different between malignant nodule and benign nodule (p=0.526). By receiver-operating-characteristic (ROC) analysis, the sensitivity was 66.7% and the specificity was 71.4% at a cut off value of 5.40 in SUV1. The sensitivity was 75% and the specificity was 71.4% at cut off value of 7.45 in SUV2. CONCLUSION: There was a statistically significant difference in SUV1 and SUV2 between benign and malignant nodules. However, the cut off value of SUV1 and SUV2 by receiver-operating-characteristic (ROC) analysis was 5.40 and 7.45 which is different from previous studies. Therefore, studies on a larger sample of patients are required for confirmation.

AbstractAbstract PDF
Chronic obstructive pulmonary disease (COPD) is characterized by a not entirely reversible limitation in the airflow. An airflow limitation is progressive and associated with an abnormal inflammatory response of the lung to gases and harmful particles. In COPD, the weight loss is commonly observed and there is a negative impact on the respiratory as well as skeletal muscle function. The pathophysiological mechanisms that result in weight loss in COPD are not fully understood. However, the mechanisms of weight loss in COPD may be the result of an increased energy expenditure unbalanced by an adequate dietary intake. The commonly occurring weight loss and muscle wasting in COPD patients adversely affect the respiratory and peripheral muscle function, the exercise capacity, the health status, and even the survival rates. Therefore, it is very valuable to include management strategies that the increase energy balance in order to increase the weight and fat free mass. A Better understanding of the molecular and cellular pathological mechanisms of COPD can improve the many new directions for both the basic and clinical investigations. The Nutritional supply is an important components of a multidisciplinary pulmonary rehabilitation program. Future studies combining an exercise program, the role of anabolic steroids, nutritional individualization, a more targeted nutritional therapy, and the development of new drugs including anti-cytokines is needed for the effective management of COPD.

AbstractAbstract PDF
Diffuse alveolar hemorrhage is a rare but serious and frequently life-threatening complication of a variety of conditions. The first goal in the management of patients with diffuse alveolar hemorrhage is to achieve or preserve stability of the respiratory status. Subsequently, the differential diagnosis is aimed at the identification of a remediable cause of the alveolar hemorrhage. The most common causes of diffuse alveolar hemorrhage with glomerulonephritis are microscopic polyangiitis and Wegener's granulomatosis, followed by Goodpasture syndrome and systemic lupus erythematosus. Microscopic polyangiitis (MPA) is a distinct systemic small vessle vasculitis affecting small sized vessels with few or no immune deposits and with no granulomatosus inflammation. The disease may involve multiple organs such as kidney, lung, skin, joint, muscle, gastrointestinal tract, eye, and nervous system. MPA is strongly associated with antineutrophil cytoplasmic autoantibody (ANCA) that is a useful serological diagnostic marker for the most common form of necrotizing vasculitis. Our report concerns a case of microscopic polyangiitis with diffuse alveolar hemorrhage in a 54-year-old man. He was admitted to our hospital due to dyspnea upon exertion and recurrent hemoptysis. Laboratory findings showed hematuria, proteinuria and deterioration of renal function. In the chest CT scan, diffuse ground glass appearance was seen in both lower lungs. A lung biopsy revealed small vessel vasculitis with intraalveolar hemorrhage and showed a positive reaction to against perinuclear ANCA. The patient was treated with prednisolone and cyclophosphamide. Chest infiltration decreased and hemoptysis and hypoxia improved. He is still being followed up in our hospital with a low dose of prednisolone.

AbstractAbstract PDF
BACKGROUND
Interleukin-1 (IL-1) and neutrophil appear to contribute to the pathogenesis of acute respiratory distress syndrome (ARDS). Elastase, as well as reactive oxygen species released from activated neutrophil, are thought to play pivotal roles in the experimental models of acute lung leak. This study investigated whether ICI 200,355, a synthetic elastase inhibitor, can attenuate acute lung injury induced by IL-1 in rats. MATERIALS AND METHODS: We intratracheally instilled either saline or IL-1 with and without treatment of ICI 200,355 in rats. Lung lavage neutrophils, lung lavage cytokine-induced neutrophil chemoattractant(CINC) concentration, lung lavage protein concentration, lung myeloperoxidase(MPO) activity and lung leak index were measured at 5 hours of intratracheal treatment. RESULTS: In rats given IL-1 intratracheally, lung lavage neutrophils, lung lavage CINC concentration, lung lavage protein concentration, lung MPO activity and lung leak index were higher. Intratracheal ICI 200,355 administration decreased lung lavage neutrophils, lung MPO activity and lung leak index, respectively, but did not decreased lung lavage CINC concentration. CONCLUSION: These results suggest that ICI 200,355 decreases lung inflammation and leak without decreasing lung lavage CINC concentration in rats given IL-1 intratracheally.

AbstractAbstract PDF
Paraganglioma is a tumor from the extra adrenal paraganglion system and is rarely observed in the mediastinum. The authors experienced a case of nonfunctioning paraganglioma of the posterior mediastinum. The patient was 34-years-old male in whom abnormal mass lesion was nites in chest radiograph with hemoptysis. His blood pressure and serologic examination were within normal range upon admission to our hospital. Chest CT revealed a tumor in the left lower lobe. Diagnostic thoracoscopy was performed and diagnosed a posterior mediastinal mass. Surgical resection was them performed. Posterior mediastinal mass was removed successfully and histological examination of the surgical specimen diagnosed paraganglioma. He received radiotherapy after surgery and was followed up. Related literature are reviewed.

AbstractAbstract PDF
BACKGROUND
In contrast to a healthy person, patients who have acute lower pespiratory tract infection with underlying pulmonary diseases have various pathogens, a rapidly progressie downhill course, and a poor response to prior antimicrobial therapy. Broad spectrum antivacterial therapy is needed for full evaluation. MATERIALS AND METHODS: To evaluate the efficacy and safety of cefpirome, we administered 1gm cefpirome, twice a day to 30 patients who had signs and symptoms of acute lower repiratory infection regardless of their underlying disease, except to those who had an allergic history to antibiotics or severe systemic diseases. RESULTS: The results were as follows : 1) Among 30 cases, 21 cases(70.0%) showed excellent improvement, and 7 cases(23.3%) showed good improvement in their symptoms and signs of acute lower respiratory infection. 2) In 14 cases with isolated pathogens, we observed bacteriologic eradication in 11 cases(78.6%). 3) Significant side effects were not found CONCLUSION: Above results suggest that cefpirome was effective as a monotherapy in patients with acute lower respriatory infection, especially on those with as underlying chronic obstructive pulmonary disease(COPD).

AbstractAbstract PDF
BACKGROUND
Lung cancer-associated hypercalcemia is one of the most disabling and life-threatening paraneoplastic desorders. Humoral hypercalcemia is responsible for most lung cancer-associated hypercalcemia. Patients with hypercalcemia are usually in the advenced atage with obvious bulky tumor and carry a poor prognosis. MATERIALS AND METHODS: Total 29 patients satisfied the following criteria: histologically proven primary lung cancer, corrected calcium level> or =10.5 mg/dL, and symptons which could possibly be attributed to hypercalcemia. In this retrospective study, we evalluated the various clinical aspects of hypercalcemia, in relation to cancer stage, histologic cell type, mass size, bone metastasis, performance status, and other possible characteristics RESULTS: Total 29 lung cancer patients with hypercalcemia were studied, and most of them had squamous cell carcinoma in their histologic finding. The incidence of hypercalcemia was significantly higher between 50 and 69 years of age, and in the advancement of cancer stage. Although serum calcium level showed positive correlation with mass size, performance statusm and bone ore frequent in the patients with higher serum calcium level. There were no differences in effectiveness among therapeutic regimens. Hypercalcemia was more frequently in the later stage of disease than during the initial diagnosis of lung cancer. Most of the patients died within 1 month after development of hypercalcemia. CONCLUSION: We concluded that hypercalcemia in lung cancer is related to extremely poor prognosis, and may be one of the causes of drath and should be treated aggressively to prevent sudden deterioration or death.

AbstractAbstract PDF
Sparfloxacin is a new synthetic quinolone antimicrobial developed at the Research Laboratories of Dainippon Pharmaceutical Co, Ltd. To evaluate the efficacy and safty of sparfloxacin in acute pulmonary infection, we administered sparfloxacina(100mg) twice in a day to 30 patients who had sign and symptoms of acute pulmonary infectious diseases regardless of their underlying lung disease for 7 days. The results were : 1) A total 30 patients were enrolled in the trial. Among them 24 cases(80%) had underlying lung problems such as chronic obstructive pulmonary disease(36.4%), bronchiectasis(36.4%), bronchial asthma(3.3%), lung cancer(3.3%). 2) In 26 cases(86.6%), we observed effective improvement, and 4 cases(13.4%) show mildly effective improvement of symptoms and signs of respiratory infection. 3) In 23 cases(73.4%), we observed bacteriological eradication in culture or decreased the number of bacteria in Gram stain which found dominantly in previous Gram stain. 4) The significant side effect was not noted. The above results suggest that sparfloxacin was effective as a first line therapy in patients with acute respiratory infection.

AbstractAbstract PDF
To evaluate the efficacy and safety of clarithromycin in acute exacerbation of chronic obstructive pulmonary disease, we administered clarithromycin(250mg) twice in a day in 30 patients with acute exacerbation of chronic obstructive pulmonary disease from September to November in 1996. Twenty eight eases of 30 patients were cured(93.4%) and 2 cases(6.7%) show clinical improvement. Three cases were improved within 3 days of treatment and 24 cases were improved between 5 days and 12 days of treatment. There were no significant side effects. These results suggest that clarithromycin will be effective as a first line therapy in patients with acute exacerbation of chronic obstructive pulmonary disease.

AbstractAbstract PDF
Adenoid cystic carcinoma is an uncommon histologic variant of adenocarcinoma which usuallyy arises from the salivary, lacrimal, or other exocrine glands. Characteristics of adenoid cystic carcinoma are its potential fo extending long distance submucosally and for perineural invasion. It grows slowly and may have a prolongec course before diagnosis and after treatment. Recently, we have experienced 2 cases of adenoid cystic carcinoma arising from main bronchus and trachea. One case was 58 years old female patient. Her symptoms were productive cough with dyspnea. She ha been history of shortness of breath, wheezing and cough during 4 years, which was initially diagnosed a bronchial asthma. The tumor was located on the left main stem bronchus which was obstructed the lumei nearly complete, by CT demonstration.

AbstractAbstract PDF
The idiopathic hypereosinophilic syndrome consists of peripheral blood eosinophilia of 1500/mm3 or more without a known cause, plus signs and symptoms of organ eosinophilia. The prognosis of HES without treatment is poor. However, about one third of the patients with this syndrome may respond to corticosteroid thrapy. Morever, the majority of the remainder may have a favorable response to hydroxyurea. We present here a case of hypereosinophilic syndrome without any identifiable causes, involving bone marrow, liver, lungs and cervical lymph node. We tried corticosteroid as a treatment but it showed no response. However the hydroxyurea showed good response.

AbstractAbstract PDF
Amiodarone has a potent suppressive effect on supraventricular and ventricular dysrhythmias, so has widely used as a class III antiarrhythmic agent. However, significant side effects were noted in over 50% of patients treated. Pulmonary toxicity represents the most serious adverse reaction limiting the clinical efficacy of this new antidysrhythmic drug. A 66-year-old male had received amiodarone 200 mg/day for 7 months to control high grade ventricular premature contraction and was admitted due to dyspnea on exertion for 1 week. At the time of admission end-inspiratory crepitant rale was heard on auscultation. The roentgenogram of his chest revealed reticular and granular radiopaque densities on both lower lung fields and high resonance CT revealed interstitial fibrosis and pneumonic consolidations on the periphery of the both middle and lower lobes. Trans-bronchoscopic lung biopsy revealed non-specific interstitial fibrosis. The laboratory findings were non-specific. We present a case of amiodarone-induced interstitial pulmonary disease clinically improved by corticosteroid therapy

AbstractAbstract PDF
Bronchial carcinoid tumor was a low grade malignant and it was regarded as predictable clinical course and good survivality after surgical resection. But despite of its low grade malignant potentiality, bronchial carcinoid tumor was clearly capable of metastasizing and causing death. We present 2 cases of bronchial carcinoid tumors. One of them was typical carcinoid tumor in 44 year-old female and another was atypical carcinoid tumor in 53 year-old male patient. Currative therapeutic procedure was performed by lobectomy and wedge resection.

AbstractAbstract PDF
The authors conducted a clinical observation of 13 cases of pulmonary aspergilloma at Yeungnam University Hospital from March 1983 to March 1992, and the following results were observed: 1) The male to female ratio was 1 : 1.2, and the age distribution was ranged 30 to 67 years old. 2) All cases were symptomatic : hemoptysis, cough, sputum and dyspnea. Especially, hemoptysis was the presenting compliant in 10 patients (77%) 3) The underlying lung disease were pulmonary tuberculosis in 9, COPD in 5 and bronchiectasis in 2. 3 cases were without underlying disease. 4) According to radiographic appearance, 8 cases had the typical crescent sign and 5 cases were seen nodular lesion. And the lesions of 11 cases were located in both upper lung. 5) 10 cases were treated with surgical resection. Among these cases, 8 cases were alieved and 2 cases, died. And other 3 cases were treated with conservative treatment. We suggest that these findings would be helpful for the diagnosis and treatment of pulmonary aspergilloma and further study might be needed to evaluate the prognosis of pulmonary aspergilloma.

AbstractAbstract PDF
High frequency ventilation (HFV) is a new ventilatory technique that uses very small tidal volume (less than the anatomic dead space) and high frequency, and classified 4 distinct types according to frequency and mode of gas delivery. The mechanism of gas transport of high frequency oscillation ventilation (HFOV) is somewhat different to other types of HFV. To evaluate the determinants of PaCO² in HFOV, a study was done with a HFOV on 9 cats, and the results are: 1) PaCO² was not correlated with frequency at the constant stroke volume (6 voltage) and bias flow (6 L/minutes). 2)PaCO² was correlated with stroke volume but not with bias flow under the constant frequency (15 Hz/min) and bias flow (3 to 6 L/min). From above results, the main determinant of PaCO² on artificial ventilation with HFOV was stroke volume, but further study between flow, the site of delivery to the airway and humidification of bias flow and CO² elimination is required in future research.

AbstractAbstract PDF
The tracheobronchial histopathologic findings in 7 healthy cats used with high frequency oscillation ventilation (HFOV) were compared with those in 6 cats used with conventional mechanical ventilation (CMV). 4-point, 9-variable scoring system was used to evaluate the injury in the trachea, right & left main bronchi and parenchyma. The following results were obtained; 1) The tracheobronchial tree received HFOV had no significant damage compared with CMV (P>0.05). 2) Intraepithelial mucus loss and emphysema were slightly more prominent in CMV groups. As above results; the tracheobronchial histopathologic difference was not prominent between CMV and HFOV groups received with relatively short period, however, the cellular of function and barotrauma may be more prominent in CMV groups. From now on, as causes of tracheobronchial injury in HFV, interaction between humidification and mechanical trauma considers further study.

AbstractAbstract PDF
Since the first cases of tsutsugamushi disease reported in Korea in 1986, many cases has been reported and its occurrence has been increasing. Only 2 cases has been reported in Taegu city and Kyungpook area. We experienced an outbreak of 26 cases of tsutsugamushi disease in this area and their clinical manifestations are; 1. The outbreak occurred in September to November in 1988 and its peak occurrence was in October. 2. Mean age was 52 years old (18 to 69 years old) and peak incidence was in the 6th decade. 3. Major symptoms and abnormal signs are fever/chills (88%), myalgia (65%), headache (54%), nausea and vomiting (31%), and abdominal pain (27%). The eschar was detected on lower part of body in most of cases, and more frequently in male (M:F 100 vs 58%). 4. Patients were treated with tetracyclines (TC) and/or chlorampenicol (CM) and mean duration of defervescence from initiation of antibiotic therapy was 2.1days with TC and 2.5 days with CM. 5. Complications are 2 cases of meningitis and 1 case of shock, and all cases were recovered without any sequelae. As above, tsutsugamushi disease occurs in Taegu city and Kyung Pook area as other part of Korea and clinical manifestations are similar to other reports.

AbstractAbstract PDF
Dissecting aortic aneurysm is relatively rare in those under 40 years of age without high risk factors. After dissecting aortic aneurysm is occurred, the coronary artery is rarely perfused by false lumen. We present a thirty two-year-old man who showed Debakey type 1 dissecting aortic aneurysm with right coronary artery perfused by false lumen of ascending aorta and with congestive heart failure due to aortic insufficiency without discernible risk factor. Medical and surgical treatment (Modified Bentall's operation) were successfully performed. The pathologic report showed combined cystic medial necrosis. Now he is well tolerated and stable only with anticoagulation during follow up 18 months.
