    Abstract Chronic obstructive pulmonary disease (COPD) is a common airway disease that has considerable impact on disease burdens and mortality rates. A large number of articles on COPD are published within the last few years. Many aspects on COPD ranging from risk factors to management have continued to be fertile fields of investigation. This review summarizes 6 clinical articles with regards to the risk factors, phenotype, assessment, exacerbation, management and prognosis of patients with COPD which were being published last year in major medical journals.

    Abstract Intraosseous hemangioma is very rare, accounting for <1% of bone tumors. Nasal bone origin of it is even rarer. A 63-year-old female patient visited our clinic with a complaint of epiphora. On physical examination, about 2-cm-sized nontender and fixed mass was palpated along the left nasomaxillary suture area. Preoperative magnetic resonance imaging findings were consistent with intraosseous hemangioma originating from the nasal bone. Epiphora was thought to be developed due to the mass effect and a marginal resection of the mass was performed. The defect was reconstructed with a septal cartilage and porous polyethylene implant (Synpor). Postoperatively, epiphora subsided and there has been no sign of recurrence or facial deformity during 6 months of follow-up.

    Abstract Tracheal tumors are rare diseases. They can cause narrowing of a central airway, a severe respiratory distress, and death. The objective of this case series is to highlight the role of rigid bronchoscopy in diagnosing and treating carina masses which are difficult to remove surgically. Tumor excision was performed by the rigid bronchoscopic intervention. Additional treatment was administered according to the diagnosis of each individual patient. After the procedure, patients' symptoms were improved and stenotic central airways were reopened. Rigid bronchoscopy can be a good therapeutic option to reestablish airway patency and a bridge treatment for further definitive treatment.

    Abstract Background: The clinical implication of bronchodilator response (BDR) is not fully understood. However, BDR is frequently present in patients with chronic obstructive pulmonary disease (COPD). We identified the differences in clinical features regarding BDR. In addition, we divided BDR into BDR for forced expiratory volume in 1 s (FEV1) and BDR for forced vital capacity (FVC; i.e., BDR-FEV1 and BDR-FVC, respectively) and analyzed clinical significance.
    Methods: We used data from the Korea COPD Subgroup Study, a multicenter cohort study of COPD patients recruited from 54 centers in South Korea since April 2012. We analyzed differences in baseline characteristics, 1-year exacerbation rate, and 3-year FEV1 decline between BDR negative and positive patients. Moreover, we analyzed the differences in clinical features between BDR-FEV1 positive and negative patients and between BDR-FVC positive and negative patients.
    Results: Of the 2,181 patients enrolled in this study, 366 (16.8%) were BDR positive. BDR positive patients were more likely to be ever-smokers and to have a lower body mass index and higher symptom scores compared to BDR negative patients. Baseline FEV1 and FEV1/FVC were lower in the BDR positive compared to the BDR negative group (1.7 ± 0.6 and 1.6 ± 0.5, respectively, p < 0.01; 50.9 ± 12.1 and 46.5 ± 14.8, respectively, p < 0.01). BDR positive patients were more likely to have been diagnosed with asthma-COPD overlap and to receive inhaled corticosteroids (ICS) than BDR negative patients. BDR-FVC patients were more likely to be smokers, suffer from worse symptoms and have lower lung function than those with no BDR-FVC. BDR had no significant effect on 1-year moderate to severe or severe exacerbation rates or 3-year annual FEV1 decline. Interactive effects of ICS and BDR on the exacerbation rate were not significant in any group.
    Conclusions: In this study, BDR positive patients were more likely to be ever-smokers and to have worse symptoms and lung function than BDR negative patients. BDR-FVC was associated with worse symptom control and lung function compared to BDR-FEV1. However, there were no significant differences in exacerbation rate or decline in lung function in any BDR group. In addition, the effects of ICS on exacerbations were not significant in any group.

    Abstract Background: Comorbidities of chronic obstructive pulmonary disease (COPD) influence clinical characteristics and prognosis.
    Objectives: This study compared the clinical characteristics and exacerbation rate of COPD according to the presence of depression or anxiety.
    Design: This study used data from The Korea COPD Subgroup Study (KOCOSS) cohort, a nationwide prospective cohort from 54 medical centers, between April 2012 and 2019.
    Methods: Depression and anxiety were diagnosed with the Beck Depression Inventory and Beck Anxiety Inventory. Negative binomial regression analysis was performed to analyze the frequency of exacerbations in depressed patients and anxiety. Differences in lung function trajectory according to presence of depression/anxiety were analyzed using a linear mixed model.
    Results: In all, 2147 patients were enrolled. Depressed patients or anxiety had lower lung function, higher modified Medical Research Council (mMRC) grade, St. George Respiratory Questionnaire (SGRQ) score, and COPD assessment test score, and higher rates of exacerbation in the past year than those without depression/anxiety. Depressed patients had a higher frequency of moderate to severe exacerbations [Incidence Rate Ratio (IRR): 1.57, CI: 1.17-2.11,
    Conclusion: Depressed and anxious patients showed increased respiratory symptoms and exacerbation rate as well as reduced health-related quality of life, whereas there were no significant differences in changes in lung function between groups with and without depression/anxiety.

    Abstract Background: Hyperuricemia is common during tuberculosis (TB) treatment, especially in association with pyrazinamide (PZA). This study investigated the relationship between major adverse cardiovascular events (MACEs) and hyperuricemia during TB treatment.
    Methods: We conducted a single-center retrospective cohort study. From January 2010 through June 2017, we assessed all consecutive TB patients at Chonnam National University Hospital in South Korea. Hyperuricemia was defined as serum uric acid levels exceeding 7.0 mg/dL (men) and 6.0 mg/dL (women).
    Results: Of the 1,143 patients included, PZA was administered to 1,081 (94.6%), and hyperuricemia was detected in 941 (82.3%). Eight patients experienced MACEs. Multivariate analysis using logistic regression indicated that prior ischemic heart disease was associated with MACE development (OR,14.087; 95% CI,3.304-60.061; P < 0.000), while hyperuricemia was not (OR, 1.505; 95% CI, 0.184-12.299; P = 0.703). For patients without drug-resistant TB, the absence of hyperuricemia was associated with higher mortality (OR, 2.609; 95% CI, 1.066-6.389; P = 0.036), whereas hyperuricemia was associated with less worse outcomes (OR,0.316; 95% CI,0.173-0.576; P < 0.000).
    Conclusions: Although most patients treated with PZA developed hyperuricemia, it was not associated with MACE development. Hyperuricemia during TB treatment was associated with better outcomes, possibly due to consistent adherence to TB treatment.

    Abstract Purpose: We aimed to identify factors influencing smoking cessation success among cancer patients registered in an inpatient smoking cessation program at a single cancer center.
    Materials and methods: The electronic medical records of enrolled patients with solid cancer were retrospectively reviewed. We evaluated factors associated with 6-month smoking cessation.
    Results: A total of 458 patients with cancer were included in this study. Their mean age was 62.9±10.3 years, and 56.3% of the participants had lung cancer. 193 (42.1%) had not yet begun their main treatment. The mean number of counseling sessions for the participants was 8.4±3.5, and 46 (10.0%) patients were prescribed smoking cessation medications. The 6-month smoking cessation success rate was 48.0%. Multivariate analysis showed that younger age (<65 years), cohabited status, early stage, and the number of counseling sessions were statistically significant factors affecting 6-month smoking cessation success (
    Conclusion: Smoking cessation intervention must be considered when establishing a treatment plan immediately after a cancer diagnosis among smokers.

    Abstract Rational: Hemocoagulase, a hemostatic, is used in patients with trauma, gastrointestinal bleeding, or pulmonary hemorrhage or those undergoing surgery. However, paradoxical bleeding after hemocoagulase administration is not considered a clinically significant adverse effect. Here, we report a case of paradoxical pulmonary hemorrhage associated with hypofibrinogenemia after administration of the hemocoagulase batroxobin in a patient with hemoptysis.
    Patient concerns: An 86-year-old woman complained of hemoptysis during hospitalization with organophosphate poisoning. Hemocoagulase was administered to manage bleeding; however, bleeding signs, such as hemoptysis, massive epistaxis, and ecchymosis, recurred.
    Diagnoses: The patient was diagnosed with acquired hypofibrinogenemia on the basis of the reduced plasma fibrinogen level after hemocoagulase administration and lack of other causes of bleeding.
    Intervention: Hemocoagulase administration was discontinued, and fibrinogen-containing plasma products were administered.
    Outcomes: The plasma fibrinogen level normalized and bleeding signs did not recur.
    Lessons: It is necessary to measure plasma fibrinogen levels regularly in patients undergoing hemocoagulase administration and discontinue its administration when acquired hypofibrinogenemia is detected.
