Tracheal tumors are uncommon comprising less than 0.1% of all malignancies. Metastatic tracheal tumors, especially form the extrathoracic sites, are exceedingly rare. Ovarian cancer tends to metastasize to the serous cavities and the lymph nodes. One large autopsy study reported tracheal involvement in 1% of patients who had died from ovarian cancer. Other studies have not mentioned tracheal involvement at all. Since the main symptoms of cough, hemoptysis, or wheezing are nonspecific, patients may be initially treated for other conditions including asthma or bronchitis. Here we describe a metastatic tracheal tumor from an overain carcinoma that was initally treated for bronchial asthma.

Tracheopathia osteoplastica is a rare, benign pathologic condition chahacterized the occurrence of numerous cartilage and bony nodules within the tissue of mucosa. We report a case of tracheopathia osteoplastica that involved both larynx and trachea. The patient was 73 years old male and had hoarseness. The neck CT showed thickened and irregular wall of the trachea extending to the level of the carina with multiple calcified nodules and plaques of bony density projecting into the lumen.

A 81-year-old man was referred for respiratory failure by emergency medical technicians. He admitted at intensive care unit for ventilator treatment. Several hours before admission, he took sildenafil 100 mg for erectile dysfunction without prescription. The episodes of hemoptysis occurred several hours later. Computed tomography revealed multifocal diffuse ground-glass attenuation in both lungs. And the more we performed bronchoalveolar lavage, the more the color of it was turned into red. We treated him with empirical antibiotics and tranexamic acid, and hemoptysis was stopped in one day after admission. But in the 5th admission day, he died from sepsis combined with pneumonia caused by Acinetobacter baumannii abruptly.

The prevention of and the controlling of symptoms, reductions in the frequency of exacerbations, and disease severity are central to the pharmacologic therapy of chronic obstructive pulmonary disease (COPD). COPD patients are inclined to be older, have more comorbidities, and use polypharmacy as a result. Long-acting inhaled muscarinic antagonists (LAMAs) is a preferred treatment modality. However, the cardiovascular (CV) safety of anti-cholinergics, including LAMA, has been an issue. In contrast, the results of the UPLIFT trial and a pooled analysis of data from 30 trials of tiotropium illustrates the association of tiotropium with reductions in the risk of all cause mortality, CV mortality and CV events. And, the UPLIFT trial provides clues regarding the additive advantages of tiotropium in COPD patients who already are using long-acting inhaled beta2 agonists and inhaled corticosteroids. Following the contribution of tiotropium as a first LAMA, new LAMAs such as aclidinium and glycopyrrolate (NVA-237) seem to be emerging.

Eosinophilic lung diseases are heterogenous disorder which are characterized by the presence of pulmonary symptoms or an abnormal chest radiograph accompanied by inflammatory cellular infiltrates in the airways and lung parenchyma which contain large numbers of eosinophils. The incidence of drug-induced pulmonary disorder is increasing, with at least 40 drug entities having been reported to cause this pulmonary disease. However, nonsteroidal anti-inflammatory drugs (NSAIDs) are rarely mentioned in the lists of drugs in published articles describing drug induced eosinophilic pneumonia. The following is a case of eosinophilic pneumonia that we believe was related to ibuprofen therapy.

BACKGROUND: Pulmonary tuberculosis is frequently accompanied with complications such as bronchiectasis, cavities, fibrosis and a deterioration of the lung function. However, there is little information available on the pathogenesis of these complications in pulmonary tuberculosis. Among the many factors involving in tissue remodeling, transforming growth factor-beta1 (TGF-beta1) is a potent stimulus of the extracellular matrix fomation and a mediator of potential relevance for airway wall remodeling. Therefore, this study examined the relationship between the radiological changes and the TGF-beta1 level in patients with pulmonary tuberculosis. METHODS: Serum and bronchoalveolar lavage fluid (BALF) were collected from total of 35 patients before treating them for active pulmonary tuberculosis, and the TGF-beta1 levels were measured using an enzyme-linked immunosorbent assay (ELISA). The BALF levels were recalculated as the epithelial lining fluid (ELF) levels using the albumin method. pulmonary function test (PFT) and high resolution computed tomography (HRCT) were performed before and after treatment. RESULTS: There was a strong correlation between the serum TGF-beta1 level and the presence of cavities (r=0.404, p=0.006), even though the BAL TGF-beta1 level showed a weak correlation with complications. In addition, there was no correlation between the TGF-beta1 levels before treatment and the changes in the PFT and HRCT during treatment. CONCLUSION: There is a correlation between the serum TGF-beta1 level and cavity formation in pulmonary tuberculosis before treatment. However, further study will be needed to confirm this.

BACKGROUND: We hypothesized that there was a relationship between body weight change and bronchodilator response (BDR) in patients with chronic renal failure (CRF) on hemodialysis (HD). Several mechanisms such as pulmonary edema due to water retention or increased permeability of alveolar capillary may play a important role in pulmonary function impairment and bronchial hyperresponsiveness in patients with CRF on HD. But, no studies have been published concerning BDR in patients with CRF on HD. This study was aimed to know the immediate effect of hemodialysis on pulmonary function and BDR in patients with CRF on HD. METHODS: This study included 30 patients with CRF on HD. We collected data including age, sex, height, pretibial and pedal pitting edema, interdialysis weight gain, postdialysis weight loss , underlying diseases, duration of HD, FEV1, FVC, FEV1/FVC, and BDR before and after HD. RESULTS: Interdialysis weight gain of the patients was 3.4 +/- 1.0 kg, and postdialysis weight loss was 3.2 +/- 0.7 kg. Before HD, FEV1, FVC, and FEV1/FVC of the patients were 89 +/- 22%, 86 +/- 19% of predicted, and 87 +/- 10 %. After bronchodilator inhalation, these parameters were changed to 95 +/- 22%, 90 +/- 19% of predicted, and 88 +/- 9% respectively. BDR was positive in 15 patients. After HD, FEV1, FVC, and FEV1/FVC of the patients were 100 +/- 23%, 94 +/- 18% of predicted, and 88 +/- 11%. After bronchodilator inhalation, these parameters were changed to 102 +/- 23%, 96 +/- 18% of predicted, and 89 +/- 8% respectively. BDR was positive in 9 patients. CONCLUSION: First, HD increases FEV1, FVC, and FEV1/FVC but little affects BDR. Second, there is no correlation between postdialysis weight loss and increases in FEV1, FVC, and FEV1/FVC after HD. Third, there is also no correlation not only between interdialysis weight gain and BDR before HD but between postdialysis weight loss and BDR after HD.

BACKGROUND: The most widely used pulmonary function test is spirometry. It is a relatively simple and noninvasive test that measures the volume of air expelled from fully inflated lungs. However, spirometry is an effort-dependent test that requires careful instruction and the full cooperation of the test subject. Because the old patients have relatively longer expiration time than the young patients, it is difficult for both old age and technician to fulfill the end of test criteria for forced vital capacity (FVC) maneuver. In the present study, we aimed to investigate whether forced expiratory volume in six seconds (FEV6) could be utilized in place of FVC in the detection of airway obstruction for the old age. METHODS: Total 353 old age (> or =65years) were enrolled in this study and performed spirometry. Subjects were divided into two groups by FEV1/FVC as the gold standard for diagnosing obstructive airway disease; Group I: 132 patients with FEV1/FVC> or =70% , Group II: 221 patients with FEV1/FVC<70% The relationship between FVC and FEV6 values were analyzed in both groups and differences between the groups were investigated. RESULTS: The mean difference of FVC and FEV6 values (FVC-FEV6) was 138.4+/-23.0 mL (5.06+/-2.86%). This difference was found to be higher in group II (189.4+/-162.5 mL, 7.0+/-5.4%) than group I (52.9+/-47.3 mL, 1.9+/-1.5%). When FEV1/FVC is taken as the gold standard, FEV1/FEV6 had negative predictive value of 87.4% and a sensitivity of 91.4% in the detection of obstructive airway disease. Conclusion: FEV6 was a relative good candidate for parameter in the detection of airway obstruction in the old age for whom it is difficult to fulfill acceptable FVC maneuver. However, additional researches are needed to determine the usefulness of FEV6 in detecting obstructive airway disease of old age.

BACKGROUND: As the number of older-aged people increases, the number of elderly patients who receive critical care services is expected to increase substantially. The objective of this study was to examine the clinical characteristics and outcomes of elderly patients who receive mechanical ventilation for more than 30 days in the medical intensive care unit (MICU) at a university hospital. METHODS: We retrospectively examined forty-one elderly patients (> or =65 years old) who were receiving mechanical ventilation, from April 2004 to March 2007, for periods exceeding 30 days at the MICU at Eulji University Hospital. RESULTS: The MICU and hospitalmortality rate were 60.9% and 65.9%, respectively. The mean length of the ICU stay was 57.5 days and the mean duration of mechanical ventilation was 49.3 days. The most common reason for MICU admission was acute respiratory failure (73.2%), followed by sepsis (12.2%), neurological problems (9.8%), and gastrointestinal bleeding (4.9%). The Acute Physiology and Chronic Health Evaluation (APACHE) II scores were higher for the nonsurvivors than for the survivors (28.0 vs. 25.0, respectively, p=0.03). The nonsurvivors received more red blood cell (RBC) transfusions during their ICU stay than did the survivors (84.0% vs. 43.8%, respectively p=0.007). The factors associated with hospital death were the APACHE II score and if the patient had received a RBC transfusion. CONCLUSION: The APACHE II score and a RBC transfusion were predictors of increased hospital mortality for the elderly patients who were on prolonged mechanical ventilation. These predictors may assist physicians to make clinical decisions for this patient population.
