Subacute Progressive Hearing Loss and Lower Body Parkinsonism in Primary Sjögren's Syndrome.

In primary Sjögren's syndrome, it is extremely rare to observe subacute progressive lower-body parkinsonism with severe sensory hearing loss responsive to corticosteroid therapy. Sjögren's syndrome can cause heterogeneous symptoms; therefore, its diagnosis and introduction of treatment are prone to be delayed, particularly in cases without sicca symptoms or seronegative cases, which are more likely to be seen in patients with neurological complications. This report may help clinicians identify atypical early neurological symptoms in primary Sjögren's syndrome.

Reversible Pisa syndrome caused by chronic subdural hematoma in a patient with Parkinson's disease: a case report.

Background: Pisa syndrome (PS), characterized by lateral trunk flexion, is quite common in patients with Parkinson's disease (PD). Patients with PS are older and have a significantly longer disease duration, more severe motor phenotype, ongoing combined treatment with levodopa and dopamine agonists, and higher levodopa equivalent daily dose. We describe here, to the best of our knowledge, the first case of a woman with PD who developed acute-onset PS caused by chronic subdural hematoma (CSDH).

Two rare diseases, acute calcific retropharyngeal tendinitis, and crowned dens syndrome, mimicking meningitis: A case report.

We report two rare cases. One involved acute calcific retropharyngeal tendinitis, an inflammatory condition of the longus colli tendon triggered by the deposition of calcium hydroxyapatite crystals. The other involved crowned dens syndrome, caused by pseudogout of the atlantoaxial junction following deposition of calcium pyrophosphate dehydrate or calcium hydroxyapatite.
