The rapid aging of the population has led to an increase in the number of cutaneous squamous cell carcinoma (cSCC) cases among the older population. However, the characteristics of these cases remain unclear. In this study, we aimed to identify the problem by analyzing the clinical characteristics of patients with cSCC aged 90 years and over.

Recently, the usefulness of liver native T1 mapping in magnetic resonance imaging (MRI) in adulthood has been reported. To evaluate the usefulness of native liver T1 mapping in children with congenital heart disease (CHD), we investigated the utility of native liver T1 relaxation time (LT1) in pediatric Fontan patients in comparison to other CHDs.

This study aimed to investigate the frequency and clinical features of ILD in patients with psoriasis and propose a new conceptual framework of "ILD associated with psoriasis".
Methods: A retrospective analysis of 117 patients with psoriasis was conducted, excluding those without chest imaging prior to methotrexate or biologic use and those with other comorbidities leading to ILD.
Article Synopsis
- Subacute cough is a specific type of cough lasting 3-8 weeks and is primarily caused by cough variant asthma, atopic cough, and sinobronchial syndrome, rather than post-infectious cough as previously believed.
- In a study involving 148 patients, 68.3% developed chronic cough, often stemming from multiple underlying conditions such as cough variant asthma combined with atopic cough.
- The findings highlight the need for careful diagnosis and treatment of multiple causes in patients with subacute cough to prevent progression to chronic cough.
Article Synopsis
- - Atopic dermatitis (AD) involves chronic inflammation and a weakened skin barrier, worsened by factors like scratching, and this study looks into how extracellular ATP affects AD.
- - The research found that ATP reduces filaggrin, a protein vital for skin barrier strength, and heightens inflammation by stimulating immune cell activity when released due to IL-4 and mechanical triggers.
- - Clodronate, which inhibits ATP release, shows promise in restoring filaggrin levels and reducing inflammation in a mouse model of AD, suggesting that targeting ATP could be a new way to treat this condition.
