AI Article Synopsis

  • A 7-year-old longhaired dachshund treated with cyclosporine for immune-mediated hemolytic anemia developed gingival mass lesions after 600 days of treatment.
  • Histopathological analysis revealed that these lesions were due to hyperplastic suppurative gingivitis.
  • Following a reduction in cyclosporine dosage, the dog's anemia improved and the gingival lesions significantly decreased in size and ultimately disappeared, indicating they were likely an adverse effect of the medication.

Article Abstract

Gingival mass lesions developed when cyclosporine was administered for 600 days to a female, 7-year-old, longhaired dachshund diagnosed with intractable immune-mediated hemolytic anemia (IMHA). Histopathology indicated hyperplastic suppurative gingivitis. As the anemia improved, the dosage of cyclosporine A (CsA) was markedly decreased, and the mass lesions decreased in size and disappeared, thus suggesting that the mass lesions were an adverse reaction to CsA.

Background: Neuropathologic inclusions formed by hyperphosphorylated protein tau in the brain are a hallmark of Alzheimer's disease and other human neurodegenerative disorders commonly referred to as tauopathies. Tau lesions differ in their disease-specific morphological presentations, affected cell type, subcellular compartments and tau isoforms present in the inclusions. In addition, tau filaments isolated from different tauopathies have distinct fibrillar structures that potentially underlie the morphological diversity of tau lesions.

Background: Transactive DNA-binding protein 43 (TDP-43) proteinopathy is associated with neurodegeneration, including LATE and linked to cognitive deterioration. While some research suggests a higher prevalence of TDP-43 in women, no differences have been identified among racial groups. Nonetheless, the influence of gender on cognition within the context of TDP-43 remains uncertain.

A 2-year-old female entire Golden Retriever with a history of being subdued was seen. Her physical and neurological examinations were initially unremarkable, but she acutely progressed to non-ambulatory paraparesis, with absent cervical or thoracolumbar hyperaesthesia. Magnetic resonance imaging of the vertebral column was performed, showing a well-defined, intradural-extramedullary mass at the level of the caudal aspect of L2 causing right-sided ventrolateral marked cord compression.
