Tuberculosis (TB) is one of the most important occupational risks for healthcare workers (HCWs) in South Korea. Many policies regarding the control and prevention of TB in healthcare settings recommend that HCWs are tested for latent tuberculosis infection (LTBI) in addition to active TB. Moreover, the Korean Tuberculosis Prevention Act also recommends that HCWs receive regular testing for LTBI. However, there are no specific or detailed guidelines for dealing with LTBI in HCWs. Herein, we discuss the diagnosis and treatment of LTBI in HCWs and focus particularly on the baseline screening of hired HCWs, routine follow-up, and contact investigation.

Single subcutaneous administration to S.D rats of both sexes was performed to investigate the acute toxicity of Syndella gel, a new topical drug containing deproteinised dialysate of calf's blood and micronomicin sulfate. $LD_{50}$ values for S. D rats were 23,047 mg/kg for male and 23,725 mg/kg for female. The death occurred within 24 hours after administration at doses over 19,200 mg/kg. The main cause of death seemed to be respiratory disturbance by acute shock. Major general symptoms induced by injection subcutaneously with Syndella gel were underactivity, decreased respiratory rate, salivation, tremor and loss of consciousness. No significant body weight changes and gross findings of internal organs in treatment groups in comparison with those of control groups was observed at any dose levels in Syndella gel.

We have reviewed 73 patients who experienced hemoptysis with pulmonary tuberculosis to analyze the factors contributing hemoptysis and its management The result are; 1. The age group between 30 * 50 years old was major prevalent group [59%]. 2. Sexual ratio was 3.9 to 1, as 58 men and 15 women. 3. In 58 patients [79.5 %], the number of hemoptysis in frequency was less than 5 times. 4. The quantity of hemoptysis was ranged from less than 50 ml to more than 600 ml and 20 patients [27.4%] experienced bleeding more than 600 ml at once. 5. There was no seasonal difference in hemoptysis. 6. The common prodromal symptoms of hemoptysis were coughing, fatigability, hot foreign sensation of throat in order of frequency. 7. In chest roentgenographic finding, the cavitary lesion was the most common finding, 67% [51 cases], and the multiple cavity was 19.2%[14 cases]. 8. 23 patients [31.37%] were operated for control of hemoptysis and pulmonary tuberculosis itself, 7[30.43 %] of them suffered from complication of empyema, respiratory failure, empyema with bronchopulmonary fistula. 9. One patient [4%] was died due to respiratory failure after left thoracoplasty.

The purpose of this research is to examine the effects of Scutellariae Radix(SR) extract on cytokines in ovalbumin (OVA)-induced asthmatic mice. In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 12 weeks. During this experiment, the one group was then treated with SR extract for the later 8 weeks (3 times per week) and analyzed by ELISA. There were significant decreases in IL-4(p<0.05), IL-5(p<0.05), IL-13(p<0.01), histamine(p<0.05) in serum of SR group. IgE also decreased, but was not significant compared with that of control group. The results of this study support a role for SR as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions.

Despite progress made in tuberculosis control worldwide, the disease burden and treatment outcome of multidrug-resistant tuberculosis (MDR-TB) patients have remained virtually unchanged. In 2016, the World Health Organization released new guidelines for the management of MDR-TB. The guidelines are intended to improve detection rate and treatment outcome for MDR-TB through novel, rapid molecular testing and shorter treatment regimens. Key changes include the introduction of a new, shorter MDR-TB treatment regimen, a new classification of medicines and updated recommendations for the conventional MDR-TB regimen. This paper will review these key changes and discuss the potential issues with regard to the implementation of these guidelines in South Korea.

Pulmonary tuberculosis (TB) persists as a great public health problem in Korea. Increases in the overall age of the population and the rise of drug-resistant TB have reinforced the need for rapid diagnostic improvements and new modalities to detect TB and drug-resistant TB, as well as to improve TB control. Standard guidelines and recent advances for diagnosing pulmonary TB are summarized in this article. An early and accurate diagnosis of pulmonary TB should be established using chest X-ray, sputum microscopy, culture in both liquid and solid media, and nucleic acid amplification. Chest computed tomography, histopathological examination of biopsy samples, and new molecular diagnostic tests can be used for earlier and improved diagnoses, especially in patients with smear-negative pulmonary TB or clinically-diagnosed TB and drug-resistant TB.

Purpose: This study investigated the relationships between mothers' knowledge and practice level of cough etiquette and their children's practice level of cough etiquette as perceived by their mothers. Methods: This study was a descriptive correlational study. The data were collected from 160 mothers with preschoolers attending daycare centers and kindergartens in Gwangju, South Korea using self-reported questionnaires. Results: The correct answer rate for cough etiquette knowledge in mothers was 86.0%, mothers' average practice score was 33.65±4.14, and their children's average practice score was 28.39±4.85 out of 48. The correlation between mothers' cough etiquette knowledge and practice level was not statistically significant. However, mothers' cough etiquette practice was positively correlated with children's cough etiquette level as perceived by mothers (r=.35, p<.001). Conclusion: The development of a systematic cough etiquette education program and measurements for both mothers and children according to their developmental stages is important to effectively prevent respiratory infections.

Objectives: Obstructive sleep apnea (OSA) is common in people with epilepsy (PWE), and confers medical and seizure-related consequences when untreated. Positive airway pressure, the gold-standard for OSA management, is limited by tolerability. As serotonin is involved respiratory control and amelioration of seizure-induced respiratory events, this study aims to determine whether serotonin reuptake inhibitors (SRIs) may represent a potential therapeutic option. Methods: A retrospective study of 100 PWE and OSA ${\geq}18$ years of age was conducted. The primary outcome measure was OSA severity as function of SRI use, with rapid eye movement (REM)-related OSA as a secondary outcome. Results: Older age and depression were more common in those taking an SRI. There was no association between SRIs and OSA severity. However, the SRI group was less likely to have REM-related OSA. Conclusions: In PWE and OSA, SRI use is associated with reduced risk of REM-related OSA, and may represent a potential management strategy.

An infant's sleep varies considerably from that of adults in terms of structure, amount, and breathing pattern. After birth, sleep becomes evenly distributed throughout the day and night. Nighttime sleep gradually increases with the maturation of circadian rhythm, and sleep is gradually consolidated. Electroencephalography characteristics change with age, from early and dominant active (REM) sleep in newborns to increasing NREM sleep. Similar to other elements of growth, the upper respiratory tract and ribcage gradually increase in size with age, and respiratory control also improves. With these changes, sleep patterns also change. At this time that various sleep disorders may appear. Improved understanding of age-dependent changes in infant sleep can help determine the etiology and facilitate diagnosis of infant sleep diseases.

The introduction of inhaled corticosteroids (ICS) for the management of asthma has led to a decrease in acute exacerbation of asthma. However, there are concerns regarding the safety of long-term ICS use, particularly pneumonia. Growing evidence indicates that ICS use is associated with an increased risk of pneumonia in patients with chronic obstructive pulmonary disease, whereas the risk in patients with asthma remains unclear. This review discusses the effect of ICS on pneumonia among patients with asthma to update the existing literature. Asthma is associated with an increased risk of pneumonia. Several hypotheses have been proposed to explain this association, including that asthma impairs the clearance of bacteria owing to chronic inflammation. Therefore, controlling airway inflammation with ICS may prevent the occurrence of pneumonia in asthma. In addition, two meta-analyses investigating randomized control trials showed that ICS use was associated with a protective effect against pneumonia in asthma.
