We report the case of a 74-year-old woman with Parkinson's disease (PD) who developed acute dysphagia, dysarthria, and hoarseness. A neurological examination and nasopharyngeal fiberscopy revealed paralysis of the left glossopharyngeal, vagus, and hypoglossal nerves. ⋯ She was diagnosed with zoster sine herpete unilaterally affecting multiple lower cranial nerves. Although dysphagia is common in patients with PD, acute exacerbations of dysphagia require careful investigation of various potential causes, including VZV infection.

Immune checkpoint inhibitors (ICIs) improve the outcomes of several types of cancer. However, they are also associated with various immune-related adverse events including myocarditis. ⋯ In both cases, additional immunosuppressive therapies, such as intravenous immunoglobulin and tacrolimus, successfully resolved myocarditis. Given the corticosteroid-refractory nature of these cases, we suggest that prompt addition of other immunosuppressive drugs to corticosteroid therapy should be considered in the treatment of ICI-induced myocarditis.

A 46-year-old woman with Turner syndrome (TS) (45,X/46,X,idic (X) (p11.4) mosaic) presented with a fever, unresponsiveness, hyperhidrosis, and rigidity approximately one month after episodes of confusion and suicide attempts, prompting a diagnosis of schizophrenia. Cerebrospinal fluid (CSF) showed mild hypercellularity with oligoclonal bands. Brain and abdominal magnetic resonance imaging showed no abnormalities. ⋯ Intensive immunotherapy was initiated, and the symptoms improved. Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis was diagnosed based on the presence of anti-NMDAR antibodies in her spinal fluid. This case represents a rare presentation of anti-NMDAR encephalitis in TS, which is susceptible to autoimmune disease complications.
