RESUMO
BACKGROUND/AIMS: Recently, the incidence of nursing home-acquired pneumonia (NHAP) has been increasing and is now the leading cause of death among nursing home residents. This study was performed to identify risk factors associated with NHAP mortality, focusing on facility characteristics. METHODS: Data on all patients > or = 70 years of age admitted with newly diagnosed pneumonia were reviewed. To compare the quality of care in nursing facilities, the following three groups were defined: patients who acquired pneumonia in the community, care homes, and care hospitals. In these patients, 90-day mortality was compared. RESULTS: Survival analyses were performed in 282 patients with pneumonia. In the analyses, 90-day mortality was higher in patients in care homes (12.2%, 40.3%, and 19.6% in community, care homes, and care hospitals, respectively). Among the 118 NHAP patients, residence in a care home, structural lung diseases, treatment with inappropriate antimicrobial agents for accompanying infections, and a high pneumonia severity index score were risk factors associated with higher 90-day mortality. However, infection by potentially drug-resistant pathogens was not important. CONCLUSIONS: Unfavorable institutional factors in care homes are important prognostic factors for NHAP.

BACKGROUND: There has been little data reporting the usefulness of intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter. The objective of this study is to clarify the usefulness and safety of these methods in comparison with radiologist-performed procedures. METHODS: Data of patients with pleural effusion treated with US-guided pigtail catheter drainage were analyzed. All procedures were performed from September 2012 to September. 2013 by a well-trained intensivist or radiologist. RESULTS: Pleural effusion was drained in 25 patients in 33 sessions. A radiologist performed 21 sessions, and an intensivist performed 12 sessions. Procedures during mechanical ventilation were performed in 15 (71.4%) patients by a radiologist and in 10 (83.3%) by an intensivist (p = 0.678). The success rate was not significantly different in radiologist- and intensivist-performed procedures, 95.2% (20/21) and 83.3% (10/12), respectively (p = 0.538). The average duration for procedures (including in-hospital transfer) was longer in radiologist-performed cases (p = 0.001). Although the results are limited because of the small population size, aggravation of oxygenation, CO2 retention, and decrease of mean arterial blood pressure were not statistically different in the groups. Pigtail-associated complications including hemothorax, pneumothorax, hepatic perforation, empyema, kink in the catheter, and subcutaneous hematoma were not found. CONCLUSIONS: Intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter is useful and safe and may be recommended in some patients in an intensive care unit.

A Septic embolism is a type of embolism infected with bacteria containing pus. These may become dangerous if dislodged from their original location. Embolisms of this type in the azygos vein are potentially fatal. The diagnosis of septic azygos vein embolism is difficult, so rapid diagnosis and treatment is important to avoid complications. Generally, treatment is enough for appropriate antibiotic therapy without anticoagulant therapy. We report a case of staphylococcal septic embolism in the azygos vein, which was discovered in a 51-year-old man exhibiting chest pain, dyspnea and fever. The patient was treated with antibiotic therapy alone without the use of anticoagulants.

Pulmonary alveolar microlithiasis is a rare disease of unknown etiology that is characterized by the presence of calcific concentrations in the alveolar spaces. The radiographic appearance is pathognomonic. Plain chest radiographs show a white lung or sandstorm lung consisting of fine sand like microcalcifications diffusely scattered throughout both lungs with a higher density at the lung bases. We now report the case of a 67-year-old male whose diagnosis was based on characteristic findings on a chest X-ray and a high-resolution computed tomography scan.

Because tuberculous (TB) involvement of mediastinal lymph nodes (LN) could cause false positive results in nodal staging of lung cancer, we examined the accuracy of nodal staging in lung cancer patients with radiographic sequelae of healed TB. A total of 54 lung cancer patients with radiographic TB sequelae in the lung parenchyma ipsilateral to the resected lung, who had undergone at least ipsilateral 4- and 7-lymph node dissection after both chest computed tomography (CT) and fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT were included for the analysis. The median age of 54 subjects was 66 yr and 48 were males. Calcified nodules and fibrotic changes were the most common forms of healed parenchymal pulmonary TB. Enlarged mediastinal lymph nodes (short diameter > 1 cm) were identified in 21 patients and positive mediastinal lymph nodes were identified using FDG-PET/CT in 19 patients. The overall sensitivity and specificity for mediastinal node metastasis were 60.0% and 69.2% with CT and 46.7% and 69.2% with FDG-PET/CT, respectively. In conclusion, the accuracy of nodal staging using CT or FDG-PET/CT might be low in lung cancer patients with parenchymal TB sequelae, because of inactive TB lymph nodes without viable TB bacilli.

Mycobacterium abscessus (M. abscessus) is the second most common nontuberculous mycobacteria (NTM) in South Korea. Nevertheless, the diagnosis and treatment of M. abscessus lung disease can be problematic. Surgical resection has been tried for patients with localized M. abscessus lung disease refractory to medical treatment. Here, we report on a 25-year-old woman with M. abscessus lung disease who had been diagnosed and treated three times for pulmonary tuberculosis. She was initially diagnosed as having M. intracellulare lung disease; however, M. abscessus was isolated after several months of medication. She had multiple bronchiectatic and cavitary lesions bilaterally, and M. abscessus was repeatedly isolated from her sputa despite prolonged treatment with clarithromycin, ethambutol, moxifloxacin, and amikacin. She improved only after sequential bilateral lung resection. Based on the experience with this patient, we suggest that, if medical treatment fails, surgical resection of a diseased lung should be considered even in patients with bilateral lesions.

Bone scan (BS) and serum alkaline phosphatase (ALP) concentration are used to detect bone metastasis in malignancy, although whole-body fluoro-D-glucose positron emission tomography computed tomography (FDG PET/CT) is being used increasingly. But BS is still used for the detection of metastatic bone lesion. So we compared the usefulness of PET/CT, BS, and serum ALP in detecting bone metastases in patients with newly diagnosed lung cancer. The medical record database was queried to identify all patients with a new diagnosis of lung cancer between January 2004 and December 2005, who had a PET/CT, BS, and serum ALP before treatment. We retrospectively reviewed all patients' records and radiological reports. One hundred eighty-two patients met the inclusion criteria. Bone metastases were confirmed in 30 patients. The sensitivity values were 93.3% for PET/CT, 93.3% for BS, 26.7% for serum ALP concentration, and 26.7% for BS complemented with serum ALP concentration. The respective specificity values were 94.1%, 44.1%, 94.1%, and 97.3%. The kappa statistic suggested a poor agreement among the three modalities. FDG PET/CT and BS had similar sensitivity, but PET/CT had better specificity and accuracy than BS. PET/CT is more useful than BS for evaluating bone metastasis. However, in the advanced stage, because of its high specificity, BS complemented with serum ALP is a cost-effective modality to avoid having to use PET/CT.

The observation that human matrix metalloproteinase (MMP)-8 is over-expressed in ectatic bronchi in patients with bronchiectasis suggests that polymorphisms altering the expression of MMP-8 may contribute to the susceptibility to development of bronchiectasis. We evaluated the association between the presence of bronchiectasis in a Korean population and two single nucleotide polymorphisms (SNPs) (-799C/T and -381A/G) on the promoter region of the MMP-8 gene that are reported to alter the promoter activity and thereby the gene expression. Genotyping through polymerase chain reaction (PCR) and subsequent automatic sequencing was done in 167 patients with bronchiectasis and their age-, sex-matched healthy controls to reveal that only -799C/T is polymorphic among Koreans. In the patient group with bronchiectasis, the frequency of -799C/C, C/T, and T/T genotypes were 41.9%, 49.7%, and 8.4%, respectively. A similar distribution was observed in the control group: C/C (49.7%), C/T (43.1%), and T/T (7.2%) (p=0.36). In subgroup analysis, no significant difference was observed among the patients according to; the extent of disease (p=0.76), colonization of microorganisms (p=0.56), or association of mycobacteria (p=0.17). From these results, we conclude that -799C/T on the promoter region of MMP-8 lacks association with development of bronchiectasis in Koreans.

Nephrotic syndrome has been considered a hypercoagulable state because thromboembolic events of the venous or the arterial circulations occur on occasion. There are various risk factors for thromboembolism in patients with nephrotic syndrome (membranous nephropathy, severe hypoalbuminemia, hemoconcentration and medications such as steroid and diuretics). As thromboembolism is often fatal, early detection and proper management are important. Although anticoagulation is the preferred therapy, thrombolysis may be considered for an extensive thrombosis, for inferior vena cava (IVC) thrombosis, for recurrent pulmonary thromboembolism and for bilateral renal vein thrombosis in conjunction with acute renal failure. We report here on a case of renal vein and IVC thrombosis in a 24-year-old male with nephrotic syndrome, and this patient was treated with intravenous thrombolytics rather than anticoagulation and local thrombolytic infusion. He complained of left flank pain and his CT scan revealed left renal vein thrombosis and IVC thrombosis. After urokinase infusion, his thrombi were resolved successfully without bleeding complications.

Pulmonary cavities are caused by bacterial pneumonia, fungal diseases, lung cancer, and tuberculosis (TB). However, in Korea, patients with cavitary lung lesions are generally considered to have pulmonary TB, where the incidence of TB is approximately 70 /100,000 per year. We report a case of chronic necrotizing pulmonary aspergillosis that was obscured by multidrug-resistant pulmonary TB.
