Article Synopsis
- IgA pemphigus is an autoimmune disease characterized by the presence of IgA autoantibodies targeting keratinocyte cell surfaces, resulting in skin and, rarely, oral mucosal lesions.
- A 31-year-old woman exhibited skin erythema, pustules, and erosions in her mouth, with histopathology confirming acantholysis and neutrophil infiltration.
- While typical cases of IgA pemphigus have limited oral involvement, this case highlights the presence of oral lesions as a potential indicator of anti-desmoglein 3 IgA, suggesting a rare subtype of the disease.
This study provides the first evidence that a Li ion can form ionic plastic crystals using crown ether with a bis-(trifluoromethanesulphonyl) amide (TFSA) anion. H, Li, and C nuclear-magnetic-resonance (NMR) measurements of the 15-crown-5-Li-TFSA complex revealed that the constituents underwent isotropic reorientation in the plastic crystalline phase. The NMR data of the 12-crown-4-Li-TFSA salt showed that the complex is a rotator crystal (the complexes are denoted as [Li 15C5] and [Li 12C4] in this paper).

- * Data from 1200 enrolled patients showed a decline in symptoms over time, from 93.9% during hospitalization to 33.0% at 12 months, with those experience long COVID symptoms reporting lower quality of life and higher anxiety and depression.
- * Identified risk factors for long COVID included being female, middle-aged, requiring oxygen, and being in critical condition during hospitalization, providing valuable insights for future research in Japan.
