The year of 2009~2010 brought a number of concepts and new ideas were evaluated with promising results. However, some studies that challenged many beliefs. In acute respiratory distress syndrome (ARDS), recent clinical studies took into consideration of pathophysiologic changes of respiratory system compliance. Meta-analysis of positive end-expiratory pressure trials showed survival benefit of high positive end-expiratory pressure in ARDS. Until now, prone positioning did not show survival benefit in patients with ARDS. Extracorporeal membrane oxygenation (ECMO) based management improved survival in patients with severe ARDS. ECMO can be a management option in severe ARDS. Sedation is a standard practice in critically ill patients needing mechanical ventilation. However, Danish group reported less sedation of critically ill patients receiving mechanical ventilation was associated with an increase in days without ventilation. Although this single center study has some limitations, the overall results are promising. Use of maximal sterile barrier precautions (mask, sterile gown, sterile gloves, and large sterile drapes) with chlorhexidine-impregnated dressing reduced central venous catheter related infection. Selective oropharyngeal decontamination (application of topical antibiotics in the oropharynx) reduced the mortality rate of an intensive care unit (ICU) population. Normoglycemia in Intensive Care Evaluation and Survival Using Glucose Algorithm Regulation (NICE-SUGAR) trial reported intensive glucose control increased mortality among adults in the ICU. Some of the results of above papers are promising. However, some ideas may need for more frequent individual assessment and increase the workload of ICU staffs. Before implementation of new practice in ICU, we should take into consideration of individual hospital situation including human and material resources.

Churg-Strauss syndrome (CSS), also known as allergic granulomatous angiitis, is a rare disorder characterized by the presence of asthma, eosinophilia and small-to-medium-sized vessels vasculitis. The peripheral nervous system is frequently involved in CSS, but central nervous system (CNS) involvement is rare. Furthermore, transverse myelitis (TM) as a presenting symptom in patients with CSS is extremely rare. We report here on a 60-year-old female who presented peripheral eosinophilia, lung eosinophilic infiltration, lung vasculitis, and TM. She was diagnosed as CSS based on clinical manifestation, pathologic findings, and the use of magnetic resonance imaging (MRI).

A factor VII gene -401 G/A polymorphism was identified in a patient with a pulmonary embolism. The patient was a 71-year-old woman who presented with acute-onset dyspnea. A chest CT scan revealed a pulmonary embolism. Despite the administration of low-dose warfarin as anticoagulation therapy, there was an excessively prolonged prothrombin time (PT). The blood tests revealed lower factor VII activity than normal. Full factor VII gene sequencing revealed a G to A substitution at ?401 in the promoter region. There were no other gene sequence anomalies. PCR-based analysis indicated lower factor VII gene expression in the patient than in a control subject. The data suggested the promoter polymorphism to be responsible for the lower transcription level. In conclusion, we encountered a case of Factor VII DNA polymorphism in a patient with a pulmonary embolism showing significantly reduced Factor VII activity.

Recently, subpopulations of regulatory T (Treg) cells, resting Treg (rTreg) and activated Treg (aTreg), have been discovered. The authors investigated the relationship between the change of Treg, aTreg and rTreg and autoimmune diseases. Treg cells and those subpopulations were analyzed by using the human regulatory T cell staining kit and CD45RA surface marker for 42 rheumatoid arthritis (RA), 13 systemic lupus sclerosis (SLE), 7 Behcet's disease (BD), and 22 healthy controls. The proportion of Treg cells was significantly lower in RA (3.8% +/- 1.0%) (P < 0.001) and BD (3.3% +/- 0.5%) (P < 0.01) compared to healthy controls (5.0% +/- 1.3%). The proportion of aTreg cells was also significantly lower in RA (0.4% +/- 0.2%) (P = 0.008) and BD (0.3% +/- 0.1%) (P = 0.013) compared to healthy controls (0.6% +/- 0.3%). The rTreg cells showed no significant differences. The ratio of aTreg to rTreg was lower in RA patients (0.4% +/- 0.2%) than that in healthy controls (0.7% +/- 0.4%) (P = 0.002). This study suggests that the decrement of aTreg not rTreg cells contributes the decrement of total Treg cells in peripheral blood of RA and BD autoimmune diseases. Detailed analysis of Treg subpopulations would be more informative than total Treg cells in investigating mechanism of autoimmune disease.

Ulnar neuropathy around the elbow in patients with rheumatoid arthritis can occur by synovial invasion, flexion contracture or valgus deformity of the elbow. However, attritional rupture of the ulnar nerve by medial osteophyte with synovial invasion of the rheumatoid elbow is extremely rare. We reported a case of attritional rupture of the ulnar nerve by medial osteophyte in 62 years-old male with rheumatoid arthritis. Exact diagnosis and proper treatment are required if symptoms of ulnar neuropathy present in rheumatoid arthritis with contracture and valgus deformity of the elbow.

BACKGROUND: Pulmonary embolism (PE) is a common clinical problem in the West that is associated with substantial morbidity and mortality. The diagnostic modality has been changed since 2001. This study retrospectively reviewed the PE mortality with the aim of identifying the risk factors associated with mortality since the multidetector computed tomography (MDCT) was introduced. METHODS: We analyzed 105 patients with acute PE proven by multidetector CT or ventilation perfusion scan. The primary outcome measure was the all-cause mortality at 3 months. The prognostic effect of the baseline factors on survival was assessed by multivariate analysis. RESULTS: The main risk factors were prolonged immobilization, stroke, cancer and obesity. Forty nine percent of patients had 3 or more risk factors. The overall mortality at 3 months was 18.1%. Multivariate analysis revealed low diastolic blood pressure and the existence of cancer to be independent factors significantly associated with mortality. Forty two PE patients were examined for the coagulation inhibitors. Four of these patients had a protein C deficiency (9.5%), and 11 had a protein S deficiency (26%). CONCLUSION: PE is an important clinical problem with a high mortality rate. Close monitoring may be necessary in patients with the risk factors.

BACKGROUND: A tuberculous destroyed lung is sequelae of pulmonary tuberculosis and causes various respiratory symptoms and pulmonary dysfunction. The patients with a tuberculous destroyed lung account for a significant portion of those with chronic lung disease in Korea. However, few reports can be found in the literature. We investigated the computed tomography (CT) findings in a tuberculous destroyed lung and the correlation with lung function. METHODS: A retrospective analysis was carried out for 44 patients who were diagnosed with a tuberculous destroyed lung at the Keimyung University Dongsan Hospital between January 2004 and December 2009. RESULTS: A chest CT scan showed various thoracic sequelae of tuberculosis. In lung parenchymal lesions, there were cicatrization atelectasis in 37 cases (84.1%) and emphysema in 13 cases. Bronchiectasis (n=39, 88.6%) was most commonly found in airway lesions. The mean number of destroyed bronchopulmonary segments was 7.7 (range, 4~14). The most common injured segment was the apicoposterior segment of the left upper lobe (n=36, 81.8%). In the pulmonary function test, obstructive ventilatory defects were observed in 31 cases (70.5%), followed by a mixed (n=7) and restrictive ventilatory defect (n=5). The number of destroyed bronchopulmonary segments showed a significant negative correlation with forced vital capacity (FVC), % predicted (r=-0.379, p=0.001) and forced expiratory volume in one second (FEV1), % predicted (r=-0.349, p=0.020). After adjustment for age and smoking status (pack-years), the number of destroyed segments also showed a significant negative correlation with FVC, % predicted (B=-0.070, p=0.014) and FEV1, % predicted (B=-0.050, p=0.022). CONCLUSION: Tuberculous destroyed lungs commonly showed obstructive ventilatory defects, possibly due to bronchiectasis and emphysema. There was negative correlation between the extent of destruction and lung function.

Pyoderma gangrenosum (PG) is a rare disease that causes chronic skin ulcers, and it has recently been known to be related to changes in the immune system such as dysfunction of neutrophils. Over 50% of patients with PG have an underlying systemic disease, and rarely are there various medicines causing the disease, including iodide, bromide, and isotretinoin. A 49-year-old man had recurrent skin ulcers in his lower extremities. He had a history of taking propylthiouracil (PTU) for 10 years as a treatment for Graves' disease. Here, we describe a case of PTU-induced ANCA positive PG in a patient with hyperthyroidism, who has been improved after the cessation of PTU.

BACKGROUND/AIMS: Anti-C-reactive protein (CRP) antibody has been introduced as a potential biologic marker in Systemic lupus erythematosus (SLE). The aim of study is to evaluate the level of anti-CRP antibody in patients with SLE. METHODS: This study investigated the relationship between levels of anti-CRP antibodies and disease activity markers, such as complement, anti-double-stranded DNA antibody, and SLE disease activity index in 34 patients with SLE. RESULTS: The serum anti-CRP antibody levels of the patients with SLE were significantly higher than those of the healthy controls (11.3 ± 5.6 µg/mL vs. 9.1 ± 2.8 µg/mL). The percentages of the positive anti-CRP antibody were 52.9% in SLE and 27.8% in controls. Disease duration of SLE showed significant correlation with the anti-CRP antibody (r = 0.234, p = 0.026). However no significant relationship was observed between the levels of anti-CRP antibodies and disease activity markers. CONCLUSIONS: These data show that the anti-CRP antibody levels of the patients with SLE were significantly higher than those of healthy controls. We observed that the presence of the anti-CRP anti-CRP antibody was not associated with disease activity of SLE.
