Tuberculosis (TB) is still a major health problem worldwide. Especially, multidrug-resistant TB (MDR-TB), which is defined as TB that shows resistance to both isoniazid and rifampicin, is a barrier in the treatment of TB. Globally, approximately 3.4% of new TB patients and 20% of the patients with a history of previous treatment for TB were diagnosed with MDR-TB. The treatment of MDR-TB requires medications for a long duration (up to 20–24 months) with less effective and toxic second-line drugs and has unfavorable outcomes. However, treatment outcomes are expected to improve due to the introduction of a new agent (bedaquiline), repurposed drugs (linezolid, clofazimine, and cycloserine), and technological advancement in rapid drug sensitivity testing. The World Health Organization (WHO) released a rapid communication in 2018, followed by consolidated guidelines for the treatment of MDR-TB in 2019 based on clinical trials and an individual patient data meta-analysis. In these guidelines, the WHO suggested reclassification of second-line anti-TB drugs and recommended oral treatment regimens that included the new and repurposed agents. The aims of this article are to review the treatment strategies of MDR-TB based on the 2019 WHO guidelines regarding the management of MDR-TB and the diagnostic techniques for detecting resistance, including phenotypic and molecular drug sensitivity tests.

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.

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.
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.

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.
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.

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.
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.
BACKGROUND Malignant pulmonary nodules account for 30 to 40 percent of all solitary pulmonary nodules (SPNs). Therefore, characterization of SPNs is very important for treatment. Recently, dynamic CT has been widely used for tissue characterization and formation of differential diagnoses. The purpose of this study was to evaluate the ability of dynamic CT to formulate the differential diagnosis of SPNs. MATERIALS AND METHODS: Nineteen patients with SPNs underwent dynamic CT (unenhanced scans, followed by a series of images at 20, 40, 60, 80, 100, 120, 140, 160, and 180 sec after intravenous injection of contrast medium). Diagnosis of SPN was performed based on pathologic findings in needle biopsy samples. Peak enhancement, net enhancement, slope of enhancement, and maximum relative enhancement ratio of the SPN were measured on dynamic CT, and Levene's test was performed to assess benignancy and malignancy. RESULTS: Twelve SPNs were confirmed to have malignant pathology. There were no significant differences between benign and malignant nodules with respect to peak enhancement (p=0.787), net enhancement (p=0.135), or slope of enhancement (p=0.698). The maximal enhancement ratio was increased in malignancy compared to benignancy, but the difference was not statistically significant (p=0.094). CONCLUSION: In our study, the hemodynamic characteristics of dynamic CT were not significantly different between benign and malignant nodules. Therefore, long-term studies of larger patient samples are required to confirm our findings.
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.
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.
Background :Interleukin-1 (IL-1) and neutrophil appear to contribute to the pathogenesis of acute respiratory distress syndrome (ARDS). Reactive oxygen species, as well as elastase released from activated neutrophil, are thought to play pivotal roles in the experimental models of acute lung leak. This study investigated whether aerosolized vitamin E 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 pretreatment with aerosolized vitamin E in rats. After 5 hours of intratracheal instillation, lung lavage neutrophils, lung lavage protein concentration, lung myeloperoxidase(MPO) activity and lung wet weight to dry weight ratio(WW/DW) were measured in rat.
Results :In rats given IL-1 intratracheally, lung lavage neutrophils, lung lavage protein concentration, lung MPO activity and WW/DW were higher. Pretreatment with aerosolized vitamin E decreased lung lavage neutrophils, lung MPO activity and WW/DW in rats given IL-1 intratracheally.
Conclusion :These results suggest that direct pulmonary supplement of vitamin E decreases lung inflammation and leak in rats given IL-1 intratracheally.
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.
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.
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.
Unilateral absence of a pulmonary artery (UAPA) is a rare congenital anomaly that is frequently associated with other cardiovascular anomalies first reported by Fraentzel in 1968. Most patients who have no associated cardiac anomalies have only minor or absent symptoms. We experienced a case of isolated UAPA in a young female presenting hemoptysis. The chest radiograph showed a small left lung volume and high resolutional CT of chest showed multiple subpleural nodules and centrilobular nodules in parenchyma. The video-assisted thoracoscopic biopsy revealed diffuse dilated vessels in visceral pleura. The pulmonary angiogram confirmed the absence of the left main pulmonary artery.
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.
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.
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).
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.
Although traditionally viewed as a physical barrier between the host and a variety of inhaled irritants and pathogens, it has become clear that the epithelium has a much broader functional scope. Epithelial cells are metabolically active and can play an important role in the regulation of the allergic inflammatory response. This review preview provides a consideration of the role of the epithelial cell as both a "target" for exogenous and endogenous stimuli and as an "effector" cell that is capable of producing a variety of products that can influence the inflammatory response in the airways.
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.
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.
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.
To evaluate the isolation rate of acid-fast bacilli on Ziehl-Neelsen stain from biopsy specimens of extrapulmonary tuberculosis proven by chronic granulomatous inflammation, 286 cases of extrapulmonary tuberculosis were reviewed and the results are as follows : 1) Mean age was 27.3 years old and lymphatic tuberculosis was more prevalent in the female but others were more common in the male. 2) The most common site of extrapulmonary tuberculosis was pleura (103 cases ; 36%) followed by lymph nodes (87 cases ; 30.4%), gastrointestinal tract (27 cases ; 9.4%), skin and soft tissue (23 cases ; 8.0%), bone (19 cases ; 6.6%), urinary tract (14 cases ; 4.6%), larynx (9 cases ; 3.2%) and breast (5 cases ; 1.8%) in order of frequencies. 3) Of 286 cases, 30.4%, (87 cases) of the biopsy specimens showed acid fast bacilli on microscopy. The isolation rate according to the sites was slightly higher in breast and lymph nodes as 3 of 5 cases (60.0%) and 35 of 87 cases (40.2%) respectively, and followed by 3 of 9 cases (33.3%) in the larynx, 4 of 13 cases (30.8%) in the urinary tract, 5 of 19 cases (26.3%) in the bone, 7 of 27 cases (25.9%) in the gastrointestinal tract, 26 of 103 cases (25.2%) in the pleura, and 4 of 23 cases (17.4%) in the skin and soft tissue, in order of frequencies. 4) The prevalence of extrapulmonary tuberculosis associated with pulmonary tuberculosis on chest X-ray was 85 of 286 cases (29.7%).
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
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.
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.
The syndrome of inappropriate ADH secretion is a disorder characterized by hyponatremia which results from water retention attributable to ADH release. The hallmark of SIADH is hyponatremia due to water retention, in the presence of urinary osmolality above plasma osmolality. The SIADH was initially described by Schwartz et al (1957). This syndrome, first recognized in patients with bronchogenic carcinoma, has now been observed in a variety of other illnesses. Recently, we encountered a 59 year-old female with small cell lung cancer, also she had SIADH. Thus, we present a case and review the literature on the subject.
Clinical observations were made on 349 cases of acute drug intoxication who were visited to emergency room of Yeungnam University Hospital during recent 7 years from January 1984 to December 1990. The following results were obtained. 1) Total number of cases of acute drug intoxication was 349 which was 0.39% of the total patients of the emergency room during the same period. 2) The ratio of male to female was 1.1:1. The age incidence was highest in the third decade (26.7%). The monthly incidence was highest in May. Higher frequency was observed in summer season. 3) The most common drug of the intoxication was pesticides and herbicides (71.9%), the remainders were miscellaneous drugs (11.2%), sedatives (7.7%), rodenticides (6.3%) and unknown drug (3.2%) in orders. 4) The most common cause of drug intoxication was suicide (69.1%) and the others were accident, unknown cause, intention in orders. 5) Main clinical manifestations were the impairment of consciousness, nausea, vomiting and convulsion. Physical examination revealed increased pulses, increased blood pressure, miosis of the pupil and sweating. Above symptoms and signs were more prominent in pesticide intoxication. Leukocytosis, glycosuria and abnormal LFT were common findings in acute intoxications. 6) The complications were developed in 18.3% among 349 cases and the most common complication was respiratory failure, pneumonia, cardiovascular collapse and pulmonary edema in orders. 7) Overall mortality rate was 8.3% of total cases and mortality rate was highest in herbicide intoxication (22.2%).
We reviewed 30 cases of superior vena cava syndrome in adult patients who were seen at the Yeungnam University Hospital from January 1985 to June 1990. The results were as follows: 1. The male-to-female ratio was 6.5:1, and the most patients were in the age group between the sixth and seventh decades. 2. The most common symptoms were dyspnea (87%) and followed by cough (63%), facial swelling (63%) and chest pain (44%) and the physical signs were dilated neck vein (97%), facial edema (93%) and facial flushing (45%) in order of frequency. 3. The simple chest x-ray findings were superior mediastinal widening (90%), right hilar mass (77%) and pleural effusion (31%). 4. Diagnosis was made by history and physical examination (100%), chest C-T scan (100%), simple chest x-ray (97%), bronchoscopy with biopsy (40%) and so on. 5. 21 cases of patients were confirmed by histology: 14 cases (46%) of bronchogenic ca, 4 cases (14%) of lymphoma, 3 cases (10%) of metastatic lung ca. Of bronchogenic ca, small cell ca was 7 cases (23%), squamous cell ca, 5 cases (17%), and unclassified cawas 2 cases (6%). 6. In response of treatment, the clinical improvement was achieved in 18 cases with radiotherapy alone, 1 case with chemotherapy only, and 6 cases with radio-chemotherapy.
The authors conducted a clinical observation of 55 cases of solitary pulmonary nodules at Yeungnam University Hospital from June 1986 to October 1990, and the following results were obtained: 1. The age distribution was ranged from 18 to 77 years, and the male-to female ratio was 1.8:1. 2. Among 55 cases of nodules, 28 cases were benign and 27 cases were malignant nodules, and of malignant nodules, the primary lung cancer was 23 cases and of benign nodules, 18 cases were tuberculoma. 3. 23 cases (41.8%) was asymptomatic and the other 32 cases were symptomatic; chest pain 12 cases, hemoptysis; 8 cases, cough; 8 cases and dyspnea; 4 cases. 4. The non-smoker-to-smoker ratio was 1:1.04, but among 23 smoker over 20 pack years, 14 cases were malignant nodules. 5. According to nodular size, there is no striking differences between benign and malignant nodules except 3-4 cm sized nodules. 6. The lobar distribution of nodules, 35 cases were in the right lung (upper lobe; 14 cases, middle lobe; 11 cases, and lower lobe; 10 cases) and 23 cases were in the left lung (upper lobe; 9 cases, lower lobe; 11 cases), and the malignant nodules were most commonly observed in the right upper lung.
