Impact of lung cancer screening with low-dose chest computed tomography on an older population: a retrospective cohort study.

Background: The older population is at high risk of lung cancer (LC). However, the importance of lung cancer screening (LCS) in this population is rarely investigated. Herein, we evaluated the effect of LCS with low-dose computed tomography (LDCT) in the older population.

Clinical outcomes of mild to moderate coronavirus disease 2019 patients treated with Regdanvimab in delta-variant outbreak: Retrospective cohort study.

Regdanvimab is a novel neutralizing antibody agent used for the treatment of coronavirus disease 2019 (COVID-19). However, the effectiveness of regdanvimab in delta-variant patients has rarely been investigated. We examined the clinical outcomes and adverse events in COVID 19 patients treated with regdanvimab in the delta-variant era.

The effect of diabetes control status on treatment response in pulmonary tuberculosis: a prospective study.

Background: Uncontrolled diabetes, unlike controlled diabetes, is associated with an impaired immune response. However, little is known about the impact of the status of diabetes control on clinical features and treatment outcomes in patients with pulmonary TB (PTB). We conducted this study to evaluate whether the status of diabetes control influences clinical manifestations and treatment responses in PTB.

Treatment response and long term follow-up results of nonspecific interstitial pneumonia.

The purpose of this study was to investigate the long-term clinical course of non-specific interstitial pneumonia (NSIP) and to determine which factors are associated with a response to steroid therapy and relapse. Thirty-five patients with pathologically proven NSIP were included. Clinical, radiological, and laboratory data were reviewed retrospectively.

Risk factors of postoperative pneumonia after lung cancer surgery.

The purpose of this study was to investigate risk factors of postoperative pneumonia (POP) after lung cancer surgery. The 417 lung cancer patients who underwent surgical resection in a tertiary referral hospital were included. Clinical, radiological and laboratory data were reviewed retrospectively.

The diagnostic accuracy of tuberculosis real-time polymerase chain reaction analysis of computed tomography-guided bronchial wash samples.

We evaluated the diagnostic accuracy of real-time polymerase chain reaction (RT-PCR) analysis of bronchoscopic wash specimens obtained using computed tomography (CT) guidance for diagnosis of pulmonary tuberculosis (TB) patients who were unable to produce sputum samples or were sputum smear-negative. Data from patients who had lesions likely to be pulmonary TB on CT images were analyzed retrospectively. Twenty-seven patients (23.

Squamous cell carcinoma arising from pulmonary hamartoma.

A 62-year-old woman was admitted for evaluation of a recently increased lung mass which had been regarded as benign for several years. Interestingly, hypermetabolism was noted in only half of the mass while standardized uptake value of the other half was very low on ¹⁸FDG PET/CT suggesting the difference in their nature. Finally, squamous cell carcinoma with hamartoma was found by pathologic examination of surgically removed tumor specimen.

Clinical manifestations and treatment outcomes of pulmonary aspergilloma.

Background: Pulmonary aspergilloma usually results from the ingrowth of colonized Aspergillus from a damaged bronchial tree, a pulmonary cyst, or from the cavities of patients with underlying lung diseases. In the present study, we analyzed the clinical features, diagnostic methods, and managements of 36 patients with pulmonary aspergilloma.

Methods: Thirty-six patients were diagnosed as having pulmonary aspergilloma at Chung-Ang University Hospital between February 1988 and February 2000.
