Background: The significance of pulmonary artery (PA) diameter in patients with non-small cell lung cancer (NSCLC) and chronic obstructive pulmonary disease (COPD) who undergo pulmonary resection has not been elucidated.
Methods: Data of 357 patients with NSCLC and COPD who underwent pulmonary resection were retrospectively reviewed. The main PA diameter, determined by preoperative computed tomography, relative to the body surface area (PBR), was used as an index of PA dilatation, and patients were divided into 2 groups using median values.
Although direct oral anticoagulants (DOAC) have become widely used, little is known about the efficacy of DOAC for isolated distal deep vein thrombosis (DVT). In-hospitalized orthopedic patients with isolated distal DVT who were diagnosed from 2016 to 2018 were enrolled and were followed for 1 year. Embolic events included symptomatic pulmonary embolism (PE) and DVT extension above the knee.

This study aimed to investigate the long-term outcomes, including the clinical course after recurrence, of patients with synchronous oligometastatic NSCLC with only brain metastases, treated with bifocal treatment.
Methods: We retrospectively analyzed 22 patients with clinical T1-4 and N0-1 NSCLC with synchronous brain metastases who were diagnosed by preoperative PET/CT and brain CT or MRI and underwent pulmonary resection for the primary site and surgery or radiation therapy for brain metastases at our institution from 2005 to 2019.
Key Clinical Message: In addition to the reentrant map, the wave speed map can be helpful in accurately identifying the CTI gap during radiofrequency application for atrial flutter(AFL). However, in complex cases involving extensive scarring and multiple low-velocity local areas, this technique may not be useful.
Abstract: A 73-year-old male patient with a history of pulmonary vein isolation and cavotricuspid isthmus ablation underwent a second catheter ablation owing to recurrent atrial flutter (AFL).
Article Synopsis
- An 85-year-old woman's severe hyponatraemia (low sodium levels) led to transient loss of consciousness and subsequent cardiac dysfunction, ultimately diagnosed as Takotsubo syndrome, indicating a heart condition triggered by stress.
- The patient was treated with hypertonic saline to gradually correct her low sodium levels, which required careful monitoring to avoid complications, and her condition improved over 14 days.
- This case highlights the importance of promptly treating severe hyponatraemia in elderly patients, raises concerns about current treatment protocols for mineralocorticoid-responsive hyponatraemia (MRHE), and suggests a possible link between MRHE and acute cardiomyopathy.
