RESUMO
Background@#Although data on post-coronavirus disease 2019 (COVID-19) conditions are extensive, the prognostic factors affecting symptom duration in non-hospitalized patients with COVID-19 are currently not well known. We aimed to investigate the various prognostic factors affecting symptom duration among outpatients with COVID-19. @*Methods@#Data were analyzed from 257 patients who were diagnosed with mild COVID-19 and visited the ‘post-COVID-19 outpatient clinic’ between April and December 2022 after a mandatory isolation period. The symptom duration was measured from diagnosis to symptom resolution. Laboratory and pulmonary function test results from their first visit were collected. @*Results@#The mean age of patients was 55.7 years, and the median symptom duration was 57 days. The development of post-COVID-19 conditions (> 12 weeks) were significantly correlated with not using antiviral drugs, leukocytosis (white blood cell > 10,000/µL), lower 25(OH)D 3 levels, forced vital capacity (FVC) < 90% predicted, and presence of dyspnea and anxiety/depression. Additionally, in multivariable Cox regression analysis, not using antiviral drugs, lower 25(OH)D 3 levels, and having dyspnea were poor prognostic factors for longer symptom duration. Particularly, vitamin D deficiency (< 20 ng/mL) and not using antivirals during the acute phase were independent poor prognostic factors for both post-COVID-19 condition and longer symptom duration. @*Conclusion@#The non-use of antivirals, lower 25(OH)D 3 levels, leukocytosis, FVC < 90% predicted, and the presence of dyspnea and anxiety/depression symptoms could be useful prognostic factors for predicting post-COVID-19 condition in outpatients with COVID-19. We suggest that the use of antiviral agents during the acute phase and vitamin D supplements might help reduce COVID-19 symptom duration.
RESUMO
Background@#This study aimed to investigate the association between e-cigarette (EC) use and development of acute severe pneumonia in the Korean population using a national database. @*Methods@#We conducted a retrospective analysis using linkage of data between the Korean National Health and Nutrition Examination Survey (KNHANES) and the National Health Insurance Service (NHIS) administrative claims database. The primary endpoint of this study was development of severe pneumonia requiring hospital admission according to EC use during the study period. The secondary endpoints were in-hospital mortality, intensive care unit (ICU) admission, ventilator care, and days of hospital stay. @*Results@#The final analysis included 28,950 individuals, of which 578 (2.0%) were EC users.EC users were younger and more often male than non-EC users. The EC users showed higher level of education and household income and had fewer comorbidities. Severe pneumonia was noted in 37 of 28,372 non-EC users (0.13%), but there were no occurrences of severe pneumonia in EC users. The incidence of pneumonia occurrence was not different between the two groups (P = 1.000). @*Conclusions@#Since e-cigarette or vaping use-associated lung injury (EVALI) is most likely included in acute severe pneumonia occurring within 3 months of EC use, it is considered that there might be no EVALI patients in Korea during the investigation period. A large-scale, prospective study is necessary to evaluate the association between EC use and acute lung injury.
RESUMO
Background@#E-cigarettes are steadily gaining popularity in Korea. However, the characteristics of e-cigarette smokers, especially nicotine dependence and stress susceptibility, have not been evaluated in comparison to those of nonsmokers or combustible cigarette smokers in Korea. @*Methods@#In this study, 28,059 participants from the Korea National Health and Nutrition Examination Survey (2013–2017) were classified into the following three groups: non-smokers, smokers (current smokers and ex-smokers of combustible cigarettes only), and e-smokers (current smokers and ex-smokers of e-cigarettes regardless of combustible cigarette use). @*Results@#Among the participants, 16,980 (60.5%), 9,247 (33.0%), and 1,832 (6.4%) subjects were non-smokers, smokers, and e-smokers, respectively. E-smokers were younger, more educated, and had a higher household income than nonsmokers or smokers. The number of e-smokers who smoked within 5 minutes of waking up (31.5% vs. 19.8%, p<0.001) and who planned to quit smoking within 6 months (39.1% vs. 35.7%, p<0.05) was greater than that of smokers. E-smokers perceived stress as “very much” (7.0% vs. 4.4%, p<0.001) and “a lot” (29.1% vs. 20.5%, p<0.001) compared to non-smokers. Suicidal ideation (6.5% vs. 4.7%, p<0.001), plans (2.4% vs. 1.3%, p<0.001), and attempts (1.1% vs. 0.5%, p<0.001) were higher in e-smokers than in non-smokers. Depressive episodes in 1 year (14.2% vs. 11.4%, p<0.05) and suicidal plans (2.4% vs. 1.8%, p<0.05) were more frequent among e-smokers than among smokers. @*Conclusion@#E-smokers were younger, more educated, and had a higher income, but they were more dependent on nicotine and susceptible to stress than non-smokers and smokers. Smoking cessation counseling should be tailored according to the characteristics of e-smokers.
RESUMO
Quitting smoking helps smokers maintain their health and extend their lifespan by 10 or more years. Treatment strategies for smoking cessation should be tailored to individual smokers with special needs based on their specific circumstances. It is recommended that pregnant women adopt smoking cessation through counseling and behavioral interventions because the safety of medications has yet to be established. Counseling is the main strategy for smoking cessation in adolescents and nicotine replacement therapy can be used with caution in individuals with serious nicotine dependence. It is important for smokers with psychiatric diseases to quit smoking following accurate assessment of their depression status. Nicotine replacement therapy, varenicline, and bupropion can be used for smoking cessation in smokers with psychiatric disorders. The incidence of cardiovascular disease decreased according to the smoking status and the duration of smoking cessation. In smokers with chronic obstructive pulmonary disease (COPD) who used a combination of counseling and pharmacotherapy the quitting rate was more than twice as high as subjects who used behavioral interventions alone. Varenicline can be used as the most effective anti-smoking drug by most smokers including those with psychiatric disorders, cardiovascular disease, and COPD.

RESUMO
OBJECTIVE: As mental health problems may play an important role in initiating and maintaining cigarette smoking in females and there are an increasing number of female smokers, we evaluated the relationship between smoking status and mental health problems including depression and suicide ideation in women in Korea. METHODS: We analyzed the 5-year cumulative data (19 years of age or older, n=32,184) from the Korean National Health and Nutrition Examination Survey (KNHANES) conducted from 2008 to 2012. Logistic regression analyses were used to evaluate associations between cigarette smoking status and mental health parameters while controlling for potentially confounding variables. RESULTS: Among current smokers, females showed higher lifetime prevalence in having a depressive episode, a doctor-diagnosed major depression, a current diagnosis of depression, or receiving treatment for depression in comparison with males. In addition, females were more likely to report on having a depressive episode, suicidal ideation and attempts, and psychiatric counselling within the previous year, as compared to males. Female former smokers showed intermediate characteristics in parameters of mental health status within the previous year, ranking between lifetime non-smokers and the current smokers. CONCLUSION: Identifying the factors related to mental health status among current smokers can increase opportunities for an early intervention and help reduce the prevalence of smoking and increase smoking cessation rates particularly in females. Developing adaptive coping strategies other than smoking in female youth is potentially important in reducing the initiation of smoking.

Extrapulmonary tuberculosis usually involves the pleura, central nervous system, lymphatic system, genitourinary system and bone with joint. There are few reports about pulmonary tuberculosis involving the endometrium and muscle. A 32-year-old woman who had intact immunity visited hospital due to menorrhagia, and was diagnosed with endometrial tuberculosis. The patient also had a painless abdominal mass about for 1 year before she came to the hospital. She was diagnosed with rectus abdominis muscle tuberculosis, endometrial tuberculosis, and pulmonary tuberculosis at the same time. We report a case of endometrial tuberculosis accompanied with rectus abdominis muscle and pulmonary tuberculosis in a non-immunosuppressed person.

Bronchopulmonary dysplasia (BPD) is related to decreased lung function throughout life. However, the pathology and radiology pattern of BPD of adults are not documented well yet. In this case report, we present BPD case of an adult monozygotic twin showing nearly identical lesions on chest computed tomography (CT). CT images showed mixed areas of ground-glass and reticular opacities in both lungs. They had common histories of pneumonias requiring mechanical ventilations in period of infants. Pulmonary function test of one patient showed a pulmonary insufficiency with airway obstruction. Pathologic findings showed bronchiolar hyperplasia and peribronchiolar fibrosis which was similar to classic BPD patients. Our twin case report might help provide distinguishing pathology and radiology pattern of an adult pulmonary sequelaes of BPD. It might be reasonable to make close follow-up for BPD patients to evaluate the long-term outcomes of BPD survivors.

We present a rare case of a pleural loose body, thought to be a pedunculated pleural tumor, found incidentally in a 58-year-old female. Computed tomography showed a non-enhancing mass, which migrated along the mediastinum and paravertebral area. Thoracoscopic surgery revealed a 4 cm, soap-like mass that was found to be a fibrin body consisting of hyalinized collagen histopathologically. Mobility and the lack of contrast enhancement of a pleural mass are important clues to diagnosing this benign condition.

Gefitinib is regarded as a relatively safe agent for the treatment of an advanced non-small cell lung cancer (NSCLC). Pulmonary toxicity such as interstitial lung disease associated with gefitinib is uncommon with an estimated all time incidence around 1% worldwide. Moreover, a case of gefitinib associated with pulmonary cystic changes has not been reported yet. In this report we present a case of progressive multiple air cystic changes in both lungs in a patient with NSCLC and intrapulmonary metastases who underwent a gefitinib therapy.

Smoking leads to nicotine addiction and serious health problems and smoking cessation can reduce the risk of developing smoking-related diseases and premature death. Smoking is a chronic disease that requires repeated interventions, including counseling and pharmacotherapy. These are both effective for smoking cessation, but combined intervention is more effective than using either alone. Several first-line medications are effective and recommended for use, such as nicotine-replacement therapy (patch, gum, inhaler, lozenge, and nasal spray), bupropion SR, and varenicline. Special populations such as adolescent smokers, pregnant women, and smokers with mental illness can be treated with both counselling and medication. Physicians should recommend effective counselling and pharmacotherapy strategies to all smokers at every clinic visit. Insurance coverage for counselling and medications for quitting smoking are essential to reduce the smoking rate, especially in a primary care setting.

Lymphadenopathy in the thoracic cavity is frequently caused by inflammatory diseases. In very rare cases, the node-bronchial fistula has been reported to be the cause of complications of pulmonary tuberculosis. A male patient with necrotizing pneumonia and mediastinal lymph node enlargements identified by chest computed tomography was also found to have a node-bronchial fistula caused by lung cancer. The patient was treated for tuberculosis with pneumonia for one week before a definitive diagnosis was made. A further investigation revealed him to have non-small cell lung cancer (NSCLC, adenocarcinoma) and multiple mediastinal lymphadenopathies accompanied with the node-bronchial fistula. We report this specific case that had been previously treated for tuberculosis but was later revealed to be NSCLC accompanied with a node-bronchial fistula.

BACKGROUND/AIMS: Obesity is a worldwide concern, but its influence on critical care outcomes is not well understood. We tested the hypothesis that abnormal body mass index (BMI) would be an independent predictor of higher mortality rates in intensive care unit (ICU). METHODS: We retrospectively reviewed patients who had admitted to the ICU from January 2007 to December 2007. Admission BMI was analyzed as both a three categorical (underweight, or = 25 kg/m2) and continuous variables among all patients with an ICU lenth of stay > or = 4 days. The primary outcome was ICU mortality. RESULTS: The multivariate analysis on ICU mortality selected Mortality Prediction Model-Admission (MPM at time zero) (hazard ratio [HR], 1.024; p = 0.001; 95% confidence interval [CI], 1.010 to 1.037), failed extubation (HR, 5.092; p = 0.0001; 95% CI, 2.742 to 9.456) as significant risk factors. When controlling these variables, none of the BMI group and BMI as a continuous variable had an independent association with ICU mortality. CONCLUSIONS: BMI did not have a significant influence on ICU mortality. The ICU mortality was influenced more strongly by severity of illness and failed extubation rather than BMI.

Although Taxol(R) is one of the most successful drugs in current cancer chemotherapy against solid tumors, a major problem is hypersensitivity reactions that arises as a consequence of activation of the complement (C) system, "C activation-related pseudo-allergy". Most severe hypersenstivity reactions occur within the first few minutes of Taxol(R) administration, usually after the first or second dose. Here we report a case of a severe hypersensitivity reaction in a 72-year-old man undergoing Genexol-PM(R) infusion. Hypotension and polymorphic pruritic skin rash appeared 2 hours after the start of Genexol-PM(R) infusion (with an appropriate premedication). Treating with methylprednisolone, epinephrine and inotropic agents, reduced the hypotension and the skin rash disappeared. We report this case with a review of the literature.

Primary neoplasm of the heart is rare. Benign tumors, the majority of which are myxomas, comprise up to 50% of cardiac neoplasms. Although cardiac myxoma is a source of emboli to the central nervous system and elsewhere in the vascular tree, its clinical signs and symptoms may be nonspecific. These nonspecific systemic symptoms and minor embolic phenomena may be overlooked in patients without a previous history of cardiac problems. Thus, we need to recognize the signs of myxoma and begin treatment immediately. We encountered a case of left atrial myxoma, presenting as pulmonary interstitial edema of unknown cause, in a 50-year-old female patient. Excision of a mass located on the left atrium was scheduled but she developed a cerebral embolism that led to her death.

BACKGROUND/AIMS: Patients with chronic airway lung diseases often experience depression and anxiety, but little information is available regarding Koreans with these conditions. We thus assessed depression and anxiety in Korean patients with chronic airway lung diseases. METHODS: The degree of depression and anxiety in 84 outpatients with chronic obstructive pulmonary disease (COPD), 37 with asthma, 33 with bronchiectasis, and 73 healthy controls were evaluated by the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). RESULTS: The patients with COPD and bronchiectasis had higher BDI scores and were more likely than controls to experience depression ([COPD, 17; range, 0 to 42; prevalence, 55%], [bronchiectasis, 16; range, 3 to 51; prevalence, 55%], [controls, 13; range, 0 to 31; prevalence, 30%], p < 0.05). The state-anxiety scores of the patients were higher than those of the controls, but only the bronchiectasis group demonstrated a higher frequency of state-anxiety compared with the controls (39 vs. 16%, patients vs. controls, p = 0.015). Among all patients, 22% presented with concomitant depression and state-anxiety, and 25% demonstrated depression and trait-anxiety. Depression was positively correlated with both state-anxiety (r = 0.644) and trait-anxiety (r = 0.597, p < 0.0001). Irrespective of individual diagnosis, post-bronchodilator FEV1 (odds ratio [OR], 0.972; p = 0.027) and smoking history (OR, 3.894; p = 0.018) were independent risk factors for depression in patients with chronic airway lung diseases. CONCLUSIONS: Chronic airway lung diseases are associated with depression and/or anxiety, particularly in those with a higher airflow limitation and/or history of smoking.

BACKGROUND: Osteoporosis is a significant comorbidity in patients with chronic obstructive pulmonary disease (COPD). This study examined the prevalence and risk factors associated with osteoporosis in patients with COPD. METHODS: The bone mineral densities (BMDs) of the lumbar spine and femoral bone were measured in 53 patients with clinically stable COPD and 41 age- and gender-matched control subjects showing a normal lung function. Osteoporosis was defined as a T-score < or =-2.5. The subjects' clinical characteristics and laboratory data were reviewed, and multiple logistic regression analysis was used to identify the risk factors associated with osteoporosis in COPD patients. RESULTS: The prevalence of osteoporosis was 47% and 32% in the COPD patients and controls, respectively. In particular, using the femoral neck T-score, the prevalence of osteoporosis in COPD patients was higher than that in the controls (26% vs. 5%; p=0.006). The average T-score of the lumbar spine (p=0.025) and femoral neck of COPD patients were significantly lower than those of the controls (p=0.001). The forced expiratory volume in the 1 second (FEV1) % predicted (p=0.019; odds ratio [OR], 0.955; 95% confidence interval [CI], 0.919-0.993) and age (p=0.024; OR, 1.144; 95% CI, 1.018-1.287) were independently associated with osteoporosis in patients with COPD. CONCLUSION: Using the femoral neck T-score, the prevalence of osteoporosis in patients with COPD was higher than the age-and gender-matched controls. A lower FEV1 and older age further increase the risk of osteoporosis in patients with COPD.

BACKGROUND: The epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), became an attractive therapeutic option for advanced non-small-cell lung cancer (NSCLC). Several studies suggested that there might be some different efficacy or response predictors between gefitinib and erlotinib. We compared the efficacy and toxicity of gefitinib and erlotinib in Korean patients with advanced NSCLC and evaluated specific predictors of response for both gefitinib and erlotinib. METHODS: We collected the clinical information on patients with advanced NSCLC, who were treated with gefitinib or erlotinib at the Ewha Womans University Hospital, between July 2003 and February 2009. Median survival times were calculated using the Kaplan-Meier method. RESULTS: Eighty-six patients (52 gefitinib vs. 34 erlotinib) were enrolled. Patient median age was 64 years; 53 (62%) subjects were male. Out of the 86 patients treated, 83 received response evaluation. Of the 83 patients, 35 achieved a response and 12 experienced stable disease while 36 experienced progressive disease, resulting in a response rate of 42% and a disease control rate of 57%. After a median follow-up of 502 days, the median progression-free and overall survival time was 129 and 259 days, respectively. Comparing patients by treatment (gefitinib vs erlotinib), there were no significant differences in the overall response rate (44% vs. 39%, p=0.678), median survival time (301 days vs. 202 days, p=0.151), or time to progression (136 days vs. 92 days, p=0.672). Both EGFR-TKIs showed similar toxicity. In a multivariate analysis using Cox regression model, adenocarcinoma was an independent predictor of survival (p=0.006; hazard ratio [HR], 0.487; 95% confidence interval [CI], 0.292-0.811). Analyses of subgroups did not show any difference in response predictors between gefitinib and erlotinib. CONCLUSION: Comparing gefitinib to erlotinib, there were no differences in the response rate, overall survival, progression-free survival, or toxicity. No specific predictor of response to each EGFR-TKI was identified.

A hiccup is caused by involuntary, intermittent, and spasmodic contractions of the diaphragm and intercostal muscles. It starts with a sudden inspiration and ends with an abrupt closure of the glottis. Even though a hiccup is thought to develop through the hiccup reflex arc, its exact pathophysiology is still unclear. The etiologies include gastrointestinal disorders, respiratory abnormalities, psychogenic factors, toxic-metabolic disorders, central nervous system dysfunctions and irritation of the vagus and phrenic nerves. Most benign hiccups can be controlled by traditional empirical therapy such as breath holding and swallowing water. However, though rare, a persistent hiccup longer than 48 hours can lead to significant adverse effects including malnutrition, dehydration, insomnia, electrolyte imbalance, and cardiac arrhythmia. An intractable hiccup can sometimes even cause death. We herein describe a patient with non-small cell lung cancer who was severely distressed by a persistent hiccup.
