BACKGROUND: Hydrocarbon is used frequently in the home in places such as the kitchen, garage, and basement. Accidental ingestion of hydrocarbons occurs generally in infants and children in the home. In cases of accidental ingestion, the amount is usually too small to cause medical problems, but can bring about diseases such as chemical pneumonitis. CASE REPORT: After ingesting organic solvent mistaken for mineral water, a 53-year-old male complained of cough, fever, and pain in the right upper abdomen, back, and right chest. Simple chest x-ray revealed focal chemical pneumonitis mainly involving the right middle lobe. The resulting lung abscess did not resolve until after treatment with drainage accompanied with antibiotics therapy. The ingested solution was analyzed and found to be a C11~C13 hydrocarbon mixture which has low viscosity. CONCLUSION: Chemical pneumonitis occurred after ingestion of hydrocarbon solution, and there is evidence of aspiratory mechanism.

BACKGROUND: Welders tend to be exposed to a variety of hazards including metal fumes, toxic gases, electricity, heat, noise, and radiation such as ultraviolet and infrared light. Noxious gases generated during welding include carbon monoxide, ozone, and nitrogen oxide. Although the effects of metal fumes have been well studied, few reports have investigated the influence of noxious gas exposure in welders. CASE REPORT: We encountered a patient who developed non-cardiogenic pulmonary edema within a day after fairing up a steel plate with an oxygen/LPG torch. The patient was a 43-year-old female who complained of dyspnea which became exacerbated the following morning. Her chest X-ray and chest CT scan showed an extensive ground glass opacity which was more prominent in the both upper lungs. Both her symptoms and chest X-ray findings improved. We attributed the patient's symptoms to non-cardiogenic pulmonary edema caused by nitrogen dioxide exposure, by reasoning that: 1) the patient's clinical course and radiologic findings suggested pulmonary edema 2) the event happened following fairing work with oxygen/LPG torch that usually induces a high concentration of nitrogen dioxide, and 3) the other possible causes of pulmonary edema could be excluded. CONCLUSION: Nitrogen dioxide-induced pulmonary edema should be considered in oxygen torch contrary to arc welding.

Although several reports about drug-resistant tuberculosis (TB) in North Korea have been published, a nationwide surveillance on this disease remains to be performed. This study aims to analyze the drug resistance patterns of Mycobacterium tuberculosis among the patients in the sanatoria of North Korea, especially during the period when second-line drugs (SLDs) had not yet been officially supplied to this country. The Eugene Bell Foundation (EBF) transferred 947 sputum specimens obtained from 667 patients from 2007 to 2009 to the Clinical Research Center, Masan National Tuberculosis Hospital (MNTH), South Korea. Four hundred ninety-two patients were culture positive for TB (73.8%). Drug susceptibility test (DST) was performed for the bacilli isolated from 489 patients. Over 3 quarters of the cases (76.9%) were multidrug-resistant (MDR)-TB. Additionally, 2 patients had extremely drug-resistant (XDR)-TB. Very high resistance to first-line drugs and low resistance to fluoroquinolones (FQs) and injectable drugs (IDs) except for streptomycin (S) were detected. A small but significant regional variation in resistance pattern was observed. Big city regions had higher rate of MDR-TB, higher resistance to FQs and IDs than relatively isolated regions. In conclusion, significant number of drug-resistant TB was detected in North Korean sanatoria, and small but significant regional variations in resistance pattern were noticeable. However, the data in this study do not represent the nationwide drug resistance pattern in North Korea. Further large-scale evaluations are necessary to estimate the resistance pattern of TB in North Korea.

Skull base osteomyelitis (SBO) is difficult to diagnose when a patient presents with multiple cranial nerve palsies but no obvious infectious focus. There is no report about SBO with septic pulmonary embolism. A 51-yr-old man presented to our hospital with headache, hoarseness, dysphagia, frequent choking, fever, cough, and sputum production. He was diagnosed of having masked mastoiditis complicated by SBO with multiple cranial nerve palsies, sigmoid sinus thrombosis, and septic pulmonary embolism. We successfully treated him with antibiotics and anticoagulants alone, with no surgical intervention. His neurologic deficits were completely recovered. Decrease of pulmonary nodules and thrombus in the sinus was evident on the follow-up imaging one month later. In selected cases of intracranial complications of SBO and septic pulmonary embolism, secondary to mastoiditis with early response to antibiotic therapy, conservative treatment may be considered and surgical intervention may be withheld.

To explore the following hypotheses: 1) Gas exchange, Organ failure, Cause, Associated disease (GOCA) score, which reflects both general health and the severity of lung injury, would be a better mortality predictor of acute respiratory distress syndrome (ARDS) than acute physiology and chronic health evaluation (APACHE II) or simplified acute physiology score (SAPS II), which are not specific to lung injury, and lung injury score (LIS) that focuses on the lung injury; 2) the performance of APACHE II and SAPS II will be improved when reinforced by LIS, we retrospectively analyzed ARDS patients (N=158) admitted to a medical intensive care unit for five years. The overall mortality of the ARDS patients was 53.2%. Calibrations for all models were good. The area under the curve of (AUC) of LIS (0.622) was significantly less than those of APACHE II (0.743) and SAPS II (0.753). The AUC of GOCA (0.703) was not better than those of APACHE II and SAPS II. The AUCs of APACHE II and SAPS II tended to further increase when reinforced by LIS. In conclusion, GOCA was not superior to APACHE II or SAPS II. The performance of the APACHE II or SAPS II tended to improve when combining a general scoring system with a scoring system that focused on the severity of lung injury.

Aspergillus tracheobronchitis is one form of invasive pulmonary aspergillosis which is characterized by ulcers and pseudomembrane formation in tracheobronchial tree. In Aspergillus tracheobronchitis, the infection is often limited to the mucosa and it accounts for less than 10 percents of invasive disease. Invasive aspergillosis mainly occurs in immunocompromized patients with prolonged neutropenia, advanced AIDS, organ transplantation, high-dose glucocorticoid therapy or cytotoxic therapy although it can occur in less immunocompromised patients, such as after influenza, COPD, old age, and diabetes. We report a case of Aspergillus tracheobronchitis in a 61 year-old patient with diabetes and Child Pugh class A liver cirrhosis. He presented with cough and purulent sputum for 10 days. He was diagnosed by bronchoscopy and successfully treated with antifungal therapy.

BACKGROUND: Paraquat is known to induce oxidant injury that results in multiorgan failure and lung fibrosis. Iron has been considered to play a key role in paraquat-induced oxidant lung injury. This study examined the effect of deferoxamine, an iron-chelating agent, in the treatment of paraquat poisoning. METHODS: From September, 2001 to April, 2005, 28 patients with paraquat poisoning who were admitted at a medical intensive care unit of a University-affiliated hospital, were enrolled in this study. Sixteen patients were treated according to the paraquat poisoning treatment guidelines and 12 received an intravenous infusion of deferoxamine in addition to the treatment guidelines. RESULTS: There were no differences between the two groups in terms of age, gender, severity of paraquat poisoning, and the time elapsed from ingestion to presentation at hospital. There was no difference in overall mortality between the two groups but the incidence of respiratory failure in the deferoxamine group was higher than in the conventional group(4/7 versus 0/9, p=0.019). CONCLUSIONS: Deferoxamine seems to have no clinical benefit compared with the conventional treatment.

Alveolar soft part sarcoma (ASPS) is a rare malignant soft-tissue neoplasm of unknown histogenesis. The two main sites of occurrence are the lower extremities in adults and the head and neck in children. We report the first case of pleural ASPS occurring in a 58-yr-old man who presented with progressive dyspnea. A computed tomographic scan of the thorax revealed a large enhancing pleural mass with pleural effusion in the left hemithorax. Wide excision of the pleural mass was performed. Histologically, the tumor consisted of organoid nests of large polygonal cells, the cytoplasm of which had eosinophilic and D-PAS positive granules. Immunohistochemical staining showed that the tumor cell nuclei were positive for transcription factor 3 (TFE3). The pleural ASPS with multiple bone metastases recurred 1 yr after surgery and the patient died of acute pulmonary embolism 1.5 yr after diagnosis.
