Based on excellent results of successive single chest thumping (CT) and serial chest thumping (SCT) for the interruption of ventricular tachycardia (VT) in experimental animals with subacute myocardial infarction, the SCT method was applied for the treatment of VT in patients with coronary artery disease (CAD). SCT was successful in terminating 13 of 19 episodes of VT (68%) in 8 of 14 patients (57%). Conversion of VT was immediate in 9 episodes in 6 patients and latent in 4 episodes in 2 patients. Complications were rare but significant. In one case, SCT resulted in a ventricular asystole and in another case SCT accelerated the rate of VT from 167/min to 242/min, requiring electroconversion. Neither a short duration of VT nor a preserved left ventricular function seemed to enhance conversion by SCT. For interruption of VT in patients with CAD, SCT is not as successful as in the experimental animal model and, therefore, should not be used as a routine method. It may be applied in selected patients under hospital conditions with a standby defibrillator.

Para-pneumonic effusion in children is often associated with bacterial infections; however, dual viral infections, including respiratory syncytial virus (RSV) and COVID-19, can also lead to severe respiratory complications, as demonstrated in this case. This case report presents the clinical course of a pediatric patient with both RSV and COVID-19 infections, leading to para-pneumonic effusion. A three-year-old girl with a history of asthma and prior febrile convulsions presented to the Emergency Department with fever, cough, vomiting, and fatigue.

We present a case of an 80-year-old female who presented with chest pain, vomiting and night sweats a few weeks post thoracic endovascular aortic aneurysm repair (TEVAR). A computed tomography (CT) scan demonstrated a type 1B endoleak for which she underwent a repeat TEVAR. Postoperatively, she developed fever, dysphagia, haematemesis and melaena.

Hereby inviting young rising stars in chest radiology in Japan for contributing what they are working currently, we would like to show the potentials and directions of the near future research trends in the research field. I will provide a reflection on my own research topics. At the end, we also would like to discuss on how to choose the themes and topics of research: What to do or not to do? We strongly believe it will stimulate and help investigators in the field.

Objective: To investigate baseline and change of pulmonary damage biomarkers (serum Krebs von den Lungen 6 [KL-6], human surfactant protein D [hSP-D], and matrix metalloproteinase 7 [MMP-7]) with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) progression.
Methods: In the Korean Rheumatoid Arthritis Interstitial Lung Disease (KORAIL) cohort, a prospective cohort, we enrolled patients with RA and ILD confirmed by chest computed tomography imaging and followed annually. ILD progression was defined as worsening in physiological and radiological domains of the 2022 American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society guideline for progressive pulmonary fibrosis (PPF).
