ABSTRACT
Background@#Although poor oral health is a common comorbidity in individuals with airflow limitation (AFL), few studies have comprehensively evaluated this association. Furthermore, the association between oral health and the severity of AFL has not been well elucidated. @*Methods@#Using a population-based nationwide survey, we classified individuals according to the presence or absence of AFL defined as pre-bronchodilator forced expiratory volume in 1 second/forced vital capacity < 0.7. Using multivariable logistic regression analyses, we evaluated the association between AFL severity and the number of remaining teeth; the presence of periodontitis; the Decayed, Missing, and Filled Teeth (DMFT) index; and denture wearing. @*Results@#Among the 31,839 participants, 14% had AFL. Compared with the control group, the AFL group had a higher proportion of periodontitis (88.8% vs. 79.4%), complete denture (6.2% vs. 1.6%), and high DMFT index (37.3% vs. 27.8%) (P < 0.001 for all). In multivariable analyses, denture status: removable partial denture (adjusted odds ratio [aOR], 1.12; 95% confidence interval [95% CI], 1.04–1.20) and complete denture (aOR, 1.52; 95% CI, 1.01– 2.05), high DMFT index (aOR, 1.13; 95% CI, 1.02–1.24), and fewer permanent teeth (0–19;aOR, 1.32; 95% CI, 1.12–1.52) were significantly associated with AFL. Furthermore, those with severe to very severe AFL had a significantly higher proportion of complete denture (aOR, 2.41; 95% CI, 1.11–3.71) and fewer remaining teeth (0–19; aOR, 2.29; 95% CI, 1.57–3.01). @*Conclusion@#Denture wearing, high DMFT index, and fewer permanent teeth are significantly associated with AFL. Furthermore, a reduced number of permanent teeth (0–19) was significantly related to the severity of AFL. Therefore, physicians should pay attention to oral health in managing patients with AFL, such as chronic obstructive pulmonary disease.
ABSTRACT
BACKGROUND@#The chronic obstructive pulmonary disease (COPD) assessment test (CAT) is a validated, eight-item questionnaire used to quantify the health status of patients. The aim of this study was to evaluate the usefulness of the CAT questionnaire as a tool to assess the response to treatment in acute exacerbations of COPD in an outpatient setting.@*METHODS@#A multicenter, phase 3 randomized controlled trial was conducted previously to examine the efficacy and safety of oral zabofloxacin for the treatment of COPD exacerbations. In the present post hoc analysis of the original study, patients with COPD exacerbation were categorized as responders or non-responders according to the respiratory symptoms persisting on day 10 (visit 3) of treatment. The CAT questionnaire was completed daily by patients at home from the initial visit to the second visit on day 5. Subsequently, the questionnaire was completed in the presence of a physician on days 10 (visit 3) and 36 (visit 4). Multivariate regression analysis was performed to determine the association between CAT scores and the therapeutic response.@*RESULTS@#The CAT scores decreased more rapidly in responders compared to non-responders during the first 5 days (23.3–20.4 vs. 23.5–22). Among responders, patients with higher severity of illness also revealed higher CAT scores on the first day of an exacerbation (mild, 19.8; moderate, 21.4; severe, 23.8; very severe, 28.6). Multivariate analysis revealed that a change in the CAT score during the first 3 days influenced the therapeutic response. A significant decrease in scores in the domains of sputum production, chest tightness, and activities of daily living was seen among responders.@*CONCLUSION@#Early improvement in CAT scores may be associated with a more favorable response to the treatment of COPD exacerbations.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01658020TRIAL REGISTRATION: Clinical Research Information Service Identifier: KCT0000532

ABSTRACT
Background@#Liberation and extubation are important for patients supported by mechanical ventilation. Extubation success is related to the duration of an intensive care unit (ICU) stay and mortality rate. High-flow nasal cannula (HFNC) oxygen therapy has physiological and clinical benefits in respiratory care. The present study compared clinical outcomes associated with HFNC and conventional oxygen therapy (COT) among patients at high risk for reintubation. @*Methods@#A single-center randomized clinical trial was conducted between March 2018 and June 2019. Sixty adults admitted to the ICU and who were at high-risk of reintubation and met the inclusion criteria were enrolled in this study. “High risk” for reintubation was defined as having at least one of the following risk factors: age > 65 years, Acute Physiology and Chronic Health Evaluation II score > 12 points on extubation day, obesity, poor expectoration, airway patency problems, difficult or prolonged weaning, and more than one comorbidity. The primary outcome of interest was reintubation within 72 hours. Secondary outcomes included duration of ICU and hospital stay, mortality rate, and time to reintubation. @*Results@#Of 60 patients, 31 received HFNC and 29 received COT (mean age, 78 ± 7.8 vs. 76 ± 6.5 years, respectively). Reintubation rate within 72 hours did not differ between the groups (3 patients [9.7%] vs. 1 patient [3.4%], respectively). Reintubation time was shorter among patients who received COT than among patients who received HFNC (0.5 hour vs. 25 hours), but this difference was not statistically significant. Duration of ICU did not differ between the groups (14.7 ± 9.6 days vs. 13.8 ± 15.7 days, for HFNC and COT, respectively). @*Conclusion@#Among patients at high risk for reintubation, compared with COT, HFNC did not reduce the risk of reintubation within 72 hours.

Background@#Lung inflammation plays a vital role in the pathogenesis of chronic obstructive pulmonary disease (COPD), but the characteristics of the inflammatory process remain unclear. There is growing interest in the role of granzyme B (GzmB) because CD8+ T cells can induce apoptosis of target cells by releasing GzmB, which in turn may cause tissue injury and remodeling. However, GzmB is also expressed by regulatory cells, which are able to suppress CD8+ T cell. The role of GzmB+ cells needs to be defined in COPD. @*Methods@#GzmB+ and CD8+ cells on alveolar wall of surgically resected lungs of microscopically classified 12 nonsmoking control, 12 panlobular emphysema (PLE) and 30 centrilobular emphysema (CLE) subjects were localized by immunohistochemical method. Positively stained cells on alveolar wall were counted and length of corresponding alveolar wall was measured. The results were expressed as mean number of positively stained cells per mm of alveolar wall in each subject. @*Results@#The number of GzmB+ and CD8+ cells on alveolar wall of CLE was greater than that of control or PLE subjects (p<0.05 and p<0.001, respectively). There was a positive relationship between the number of alveolar GzmB+ cells and forced expiratory volume in 1 second (FEV1) (r=0.610, p=0.003) in CLE subjects. The number of alveolar GzmB+ cells progressively decreased with decline of FEV1. @*Conclusion@#Our finding that number of alveolar GzmB+ cells was associated with FEV1 suggests that GzmB+ cells might have protective role in the progression of lung destruction and airflow limitation in CLE, which is the predominant emphysema subtype of COPD.

ABSTRACT
BACKGROUND: The purpose of this study was to assess the effect of our new video-assisted asthma education program on patients' knowledge regarding asthma and asthma control. METHODS: Adult asthmatics who were diagnosed by primary care physicians and followed for at least 1 year were educated via smart devices and pamphlets. The education sessions were carried out three times at 2-week intervals. Each education period lasted at most 5 minutes. The effectiveness was then evaluated using questionnaires and an asthma control test (ACT). RESULTS: The study enrolled 144 patients (mean age, 56.7±16.7 years). Half of the patients had not been taught how to use their inhalers. After participating in the education program, the participants' understanding of asthma improved significantly across all six items of a questionnaire assessing their general knowledge of asthma. The proportion of patients who made errors while manipulating their inhalers was reduced to less than 10%. The ACT score increased from 16.6±4.6 to 20.0±3.9 (p<0.001). The number of asthmatics whose ACT score was at least 20 increased from 45 (33.3%) to 93 (65.3%) (p<0.001). The magnitude of improvement in the ACT score did not differ between patients who received an education session at least three times within 1 year and those who had not. The majority of patients agreed to the need for an education program (95.8%) and showed a willingness to pay an additional cost for the education (81.9%). CONCLUSION: This study indicated that our newly developed education program would become an effective component of asthma management in primary care clinics.

Bupivacaine is frequently used for pain control and local anesthesia. However, it is associated with certain acute and fatal side effects, although rare, including cardiac and central nervous system toxicities. In particular, bupivacaine-induced cardiac toxicity may be fatal. This condition can be diagnosed as bupivacaine-induced cardiotoxicity by excluding other causes and determining a history of bupivacaine administration. However, in emergency situations, recognizing bupivacaine toxicity can be difficult due to the physician's lack of awareness regarding the condition or in the absence of clear communication regarding the patient's medical history. In the current case report, we describe our experience with strong suspected bupivacaine-induced cardiotoxicity in a patient who underwent cesarean section along with a review of the literature.

Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here we report the rare case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient was treated for aspiration pneumonia with respiratory failure in another hospital. The patient's chest wall swelling began two weeks after the initial catheterization in the other hospital, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery. Her condition improved, and she was discharged to her home.

The prognostic role of resting pulmonary hyperinflation as measured by residual volume (RV)/total lung capacity (TLC) in chronic obstructive pulmonary disease (COPD) remains poorly understood. Therefore, this study aimed to identify the factors related to resting pulmonary hyperinflation in COPD and to determine whether resting pulmonary hyperinflation is a prognostic factor in COPD. In total, 353 patients with COPD in the Korean Obstructive Lung Disease cohort recruited from 16 hospitals were enrolled. Resting pulmonary hyperinflation was defined as RV/TLC > or = 40%. Multivariate logistic regression analysis demonstrated that older age (P = 0.001), lower forced expiratory volume in 1 second (FEV1) (P < 0.001), higher St. George Respiratory Questionnaire (SGRQ) score (P = 0.019), and higher emphysema index (P = 0.010) were associated independently with resting hyperinflation. Multivariate Cox regression model that included age, gender, dyspnea scale, SGRQ, RV/TLC, and 6-min walking distance revealed that an older age (HR = 1.07, P = 0.027), a higher RV/TLC (HR = 1.04, P = 0.025), and a shorter 6-min walking distance (HR = 0.99, P < 0.001) were independent predictors of all-cause mortality. Our data showed that older age, higher emphysema index, higher SGRQ score, and lower FEV1 were associated independently with resting pulmonary hyperinflation in COPD. RV/TLC is an independent risk factor for all-cause mortality in COPD.

Sparganosis is a rare parasitic disease caused by migrating plerocercoid tapeworm larva of the genus Spirometra. Infection in humans is mainly caused by the ingestion of raw or inadequately cooked flesh of infected frogs, snakes, and chickens. Here, we report a rare case of a 45-year-old man who was admitted to our hospital with left lower chest pain. The chest radiograph and computed tomography (CT) scan revealed localized pleural effusion in the left lower lobe; further, peripheral blood eosinophilia and eosinophilic pleural effusion were present. Percutaneous catheter drainage was performed, which revealed long worm-shaped material that was identified as a sparganum by DNA sequencing. The patient showed clinical improvement after drainage of the sparganum. This study demonstrates the importance of considering parasitic diseases in the differential diagnosis of eosinophilic pleural effusion.

PURPOSE: The accurate and timely diagnosis of malignant pleural effusion (MPE) in lung cancer patients is important because MPE has a poor prognosis and is classified as stage IV disease. Molecular biomarkers for pleural effusion, such as circulating extracellular microRNAs (miRNAs) isolated from pleural fluid, may help in the diagnosis of MPE. The present study examined whether miRNAs that are deregulated in lung cancer (miR-134, miR-185, and miR-22) can serve as diagnostic markers for lung adenocarcinoma-associated MPE (LA-MPE). MATERIALS AND METHODS: Real-time reverse transcription quantitative polymerase chain reaction was used to measure the expression of the three miRNAs in samples from 87 patients with pleural effusion comprising 45 LA-MPEs and 42 benign pleural effusions (BPEs). The area under the receiver operating characteristic curve (AUC) was then used to evaluate the diagnostic performance of each of the three miRNAs and compare it with that of the common tumor marker, carcinoembryonic antigen (CEA). RESULTS: The expression of all three miRNAs was significantly lower in LA-MPE than in BPE (p <0.001). The AUCs for miR-134, miR-185, miR-22, and CEA were 0.721, 0.882, 0.832, and 0.898, respectively. Combining CEA with the three miRNAs increased the diagnostic performance, yielding an AUC of 0.942 (95% confidence interval, 0.864 to 0.982), with a sensitivity of 91.9% and a specificity of 92.5%. CONCLUSION: The present study suggests that the expression levels of circulating extracellular miR-134, miR-185, and miR-22 in patients with pleural effusion may have diagnostic value when differentiating between LA-MPE and BPE.

Aspergillus tracheobronchitis is a form of invasive pulmonary aspergillosis in which the Aspergillus infection is limited predominantly to the tracheobronchial tree. It occurs primarily in severely immunocompromised patients such as lung transplant recipients. Here, we report a case of Aspergillus tracheobronchitis in a 42-year-old man with diabetes mellitus, who presented with intractable cough, lack of expectoration of sputum, and chest discomfort. The patient did not respond to conventional treatment with antibiotics and antitussive agents, and he underwent bronchoscopy that showed multiple, discrete, gelatinous whitish plaques mainly involving the trachea and the left bronchus. On the basis of the bronchoscopic and microbiologic findings, we made the diagnosis of Aspergillus tracheobronchitis and initiated antifungal therapy. He showed gradual improvement in his symptoms and continued taking oral itraconazole for 6 months. Physicians should consider Aspergillus tracheobronchitis as a probable diagnosis in immunocompromised patients presenting with atypical respiratory symptoms and should try to establish a prompt diagnosis.

Effective treatment for community-acquired pneumonia (CAP) requires administration of appropriate empirical therapy based on etiologic, clinical, and radiological features. However, in Korea, CAP is poorly characterized, and data on viral CAP are particularly sparse. Therefore, improper use of antibiotics is common, and is detrimental the potential for development of bacterial. Thus, we investigated clinical and radiological findings for discrimination of viral CAP from bacterial CAP. Etiologic, clinical, and radiological data from 467 patients with CAP at Chungbuk National University Hospital from October 2010 to September 2011 were analyzed retrospectively. Viruses were identified in 23 cases (11.4%); the influenza virus A was the most common virus detected (N=18, 25.4%), followed by the respiratory syncytial virus A (N=14, 17.9%). Bacteria were identified in 48 cases (23.8%); Streptococcus-pneumonia was the most common (N=24, 25.5%), followed by Staphylococcus aureus (N=20, 21.3%). Depending on hospitalization time, the following significant differences were observed between viral and bacterial CAP: on admission, (1) high fever (> or = 38.5degrees C), (2) purulent sputum, (3) white blood cell count, (4) C-reactive protein levels, (5) and bilateral lung involvement on chest X-ray were higher in bacterial CAP; and at discharge, (1) duration of high fever and (2) radiologic improvement within three days were higher in viral CAP. Regarding seasonal patterns, both viruses and bacteria have been identified with relative frequency in the winter season. This study described the etiological, clinical, and radiological findings of viral and bacterial CAP. Conduct of additional large-scale, prospective investigations will be required in order to improve the appropriate treatment of CAP.

BACKGROUND/AIMS: Real-time, convex probe endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is used for the staging of malignant mediastinal lymph nodes. We evaluated the diagnostic efficacy and safety of EBUS-TBNA when used as an initial diagnostic tool. METHODS: We retrospectively studied 56 patients who underwent EBUS-TBNA as an initial diagnostic tool between August 2010 and December 2011. Procedure purpose were classified into four categories: 1) intrathoracic masses adjacent to the central airway; 2) enlarged lymph nodes for concurrent diagnosis and staging in suspected malignancy; 3) enlarged lymph nodes in suspected malignancy cases with inability to perform percutaneous core needle biopsy (PCNB); and 4) solely mediastinal masses/lymph nodes in lieu of mediastinoscopy. RESULTS: The diagnostic accuracy of EBUS-TBNA regardless of procedure purpose was calculated to be 83.9%. Furthermore, the diagnostic accuracy of malignant disease was significantly higher than benign disease (93.9% vs. 70.6%, p < 0.001). The diagnostic accuracy of EBUS-TBNA for each disease is as follows: tuberculosis, 50%; sarcoidosis, 60%; aspergillosis, 100%; lung abscess, 100%; lung cancer, 93%; and lymphoma, 100%. There were minor complications in seven patients during the EBUS-TBNA procedure. The complications included mild hypoxia and bleeding. CONCLUSIONS: In conclusion, EBUS-TBNA is a useful initial diagnostic tool for both benign and malignant diseases. EBUS-TBAN is also a very safe procedure and less invasive compared to mediastinoscopy or PCNB.

Invasive pulmonary aspergillosis (IPA) has emerged as a severe infection in patients with immunocompromised hosts. However, recently, several IPA cases, without an apparent predisposition to immunodeficiency, has been reported. A 72-year-old woman was admitted for evaluation of general weakness and poor oral intake. She reported no medical history, except for intraarticular injection of a corticosteroid for joint pain for the duration of two months. A chest radiography revealed multiple cavitary nodules in both lungs. Examination of specimens, obtained by percutaneous needle biopsy, led to a diagnosis of invasive aspergillosis. Brain magnetic resonance imagining revealed numerous peripheral thin enhancing cystic nodules in both cerebral hemispheres. We initiated intravenous administration of amphotercin B. However, the patient died after nine days. Here, we report an invasive aspergillosis case, which involves the lungs and brain after a short period of steroid injection.

Mucormycosis is a fatal opportunistic fungal infection that typically occurs in immunocompromised patients. The classical manifestation of mucormycosis is a rhinocerebral infection, and although primary gastrointestinal infection is uncommon, it has an extremely high mortality rate in immunocompromised patients. Furthermore, cases of gastrointestinal mucormycosis in an immunocompetent host are rarely reported. Here, we describe our experience of a male patient, with no underlying disease, who succumbed to a bowel infarction caused by intestinal mucormycosis during mechanical ventilatory care for severe pneumonia and septic shock.
