In recent years, there has been an increasing number of studies on neurological symptoms induced as paraneoplastic neurological syndrome (PNS) or neurological immune-related adverse events (irAEs) in patients treated with immune checkpoint inhibitors (ICIs). Herein, we report a 68-year-old male patient with small-cell lung cancer who developed memory impairment and autonomic nervous system dysfunction after three courses of carboplatin, etoposide, and durvalumab therapy. Brain magnetic resonance imaging revealed hyperintense areas restricted to the bilateral temporal lobes.

Background: Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare tumors with low malignant potential that usually occur in young girls and women. This study investigated the treatment experiences and outcomes after surgery for pediatric SPNs in our institutions as pediatric case series of solid SPNs are few, and long-term follow-up is also limited.

Methods: We retrospectively reviewed the outcomes of nine patients diagnosed with SPNs who underwent surgery in our three hospitals (The Jikei University Hospital, The Jikei University Kashiwa Hospital, and Kawaguchi Municipal Medical Center) between 2001 and 2023.

Introduction: Estimated continuous cardiac output (esCCO) is a novel technology that enables non-invasive and continuous monitoring of cardiac output. We compared the concordance in accuracies among esCCO measurements in the shunt limb and non-shunt limb.

Methods: In this single-center prospective observational study, we include Japanese patients who underwent dialysis at our center between April 27, 2021, and February 28, 2023.
