Brain with coexistent acoustic schwannoma and ependymoma.
BMC Geriatr
January 2025
Department of Neurosurgery, Xijing Hospital, Fourth Military Medical University, Xi'an, 710032, China.
Background: This particular case is a world-first with no previous literature reports on patients presenting with both benign acoustic schwannoma and malignant ependymoma.
Case Presentation: A 60-year-old woman with unexplained right-sided hearing loss that had worsened progressively over 4 years, along with intermittent dizziness that had begun 3 years prior. Our preliminary diagnosis included: (1) Right acoustic neuroma; (2) Ependymoma of the fourth ventricle; and (3) Hydrocephalus.
Alpha-synuclein inhibits the secretion of extracellular vesicles through disruptions in YKT6 lipidation.

Parkinson's disease is characterized by the presence of α-synuclein (α-syn) primarily containing Lewy bodies in neurons. Despite decades of extensive research on α-syn accumulation, its molecular mechanisms have remained largely unexplored. Recent studies by us and others have suggested that extracellular vesicles (EVs), especially exosomes, can mediate the release of α-syn from cells, and inhibiting this pathway could result in increased intracellular α-syn levels.

Internal Medicine, Holy Family Hospital, Rawalpindi, Pakistan.
Background: Andersen-Tawil syndrome (ATS) is a rare autosomal dominant disorder caused by variants in the gene. It is associated with periodic paralysis, dysmorphic features and cardiac arrhythmias. The syndrome exhibits incomplete penetrance, leading to a broad spectrum of clinical manifestations, making diagnosis challenging.

Center for Complementary Medicine, Department of Internal Medicine II, Faculty of Medicine, Medical Center - University of Freiburg, University of Freiburg, 79106, Freiburg, Germany.
Background: Crohn's disease and irritable bowel syndrome may both cause abdominal pain and diarrhea. Irritable bowel syndrome not only is an important differential diagnosis for Crohn's disease but also occurs in one out of three patients with Crohn's disease in remission in parallel. If not adequately diagnosed and treated, additional functional symptoms such as fatigue and/or muscle pain may develop, indicating a more severe course.
View Article and Find Full Text PDFBackground: Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF).
Aims: This study aimed to characterize patients with exertional dyspnoea and normal/near-to-normal N-terminal pro-brain natriuretic peptide (NT-proBNP) levels with regard to early stages of HFpEF and non-cardiac causes.
