Background: Placental transmogrification of the lung is a very rare benign lung disease with a characteristic finding being alveoli resembling chorionic villi of the placenta. The purpose of this study was to assess the computed tomography (CT) findings of placental transmogrification of the lung in six patients and their relation to the histopathologic findings.
Methods: Six patients with histopathologically proven placental transmogrification of the lung from 2004 to 2021 were included.

Smoking-related mortality among women has also not declined. Therefore, this study aimed to characterize sociodemographic features, smoking-related behaviors, mental illness, and smoking cessation in woman smokers in Korea who were registered in the Quitline program.

This study investigates awareness and perception of HTPs among tobacco users and whether perceptions of HTPs are associated with HTP use and intention to quit.
Methods: We invited 2,000 tobacco users aged 19-65 years with countrywide representation to an online survey in November 2018.
Unlabelled: The aim of this study was to evaluate the effect of additional motivational enhancement through telephone-based counseling on short- and long-term smoking abstinence among Korean adolescents.
Methods: A comparative retrospective study was conducted based on the longitudinal follow up in Quitline from 2010 to 2017. A total of 533 and 178 adolescent smokers voluntarily participated in the 1-year quitting counseling only (group A, who were ready to quit) and the additional 4-week motivational interviewing before 1-year quitting counseling (group B, who were ambivalent about quitting), respectively.
Introduction: While tobacco control policies have been adopted and enforced, and anti-smoking campaigns have been conducted, the evaluation of their impact on tobacco quitting is lacking in Korea. Therefore, the effectiveness of tobacco control policies and mass media campaigns to encourage use of the Quitline were evaluated by monitoring call volume on Quitline, which has been in operation since 2006, in Korea.
Methods: Tobacco control policies and mass media campaigns, from 1 January of 2007 to 31 December of 2016, were assessed from the review of government documents and the history of law and regulation changes.
To reduce tobacco use and related harm in Korea, telephone based cessation services (Quitlines) began full operation to provide regular behavioral counseling for smoking cessation in 2006. After registration in the cessation program, at least 21 calls per year are given to each client to help quit and encourage maintenance. Tailored programs for males, females, and adolescent smokers have been offered taking into account smokers' characteristics and smoking behavior.

Methods: The cost of the service (staff salary, medication, education and promotion and overhead) was calculated from the Smoking Cessation Clinic's 2009 financial report. The number of service users, self-reported 4-week and 6-month quit rates and the proportion of nicotine replacement therapy users were collected from the service's performance monitoring data.
Introduction: There is a lack of studies on Quitline user satisfaction and its potential value to aid in understanding user demand and improve Quitline services. This study evaluated Quitline user satisfaction and its impact on smoking cessation, in order to assess the service's quality and performance in the Republic of Korea.
Methods: Between 2007 and 2009, 3,054 Quitline users were invited to participate in an investigation of user satisfaction and its impact on successful smoking cessation.
The aim of this study elucidated the effectiveness of Quitline among adolescent smokers, as well as other factors associated with adolescent smoking cessation in the Republic of Korea. For 642 adolescent Quitline users aged 13-19 years, the information on demographic characteristics, smoking and cessation related factors, and cessation outcome was collected. Cox proportional hazard models were applied.

Methods: The NO donor sodium nitroprusside was administered to rat articular chondrocytes that had been pretreated with cilostazol. Induction of apoptosis was evaluated by DNA electrophoresis and pulsed-field gel electrophoresis.
