Progressive encephalomyelitis with rigidity and myoclonus (PERM).

Progressive encephalomyelitis with rigidity and myoclonus (PERM) is a subtype of stiff-person syndrome (formerly stiff-man syndrome). It is rare and disabling, and characterised by brainstem symptoms, muscle stiffness, breathing issues and autonomic dysfunction. We describe a 65-year-old man who presented with odynophagia together with tongue and neck swelling, followed by multiple cranial nerve palsies culminating in bilateral vocal cord paralysis with acute stridor. He subsequently developed progressive generalised hypertonia and painful limb spasms. Serum antiglycine receptor antibody was strongly positive, but antiglutamic acid decarboxylase and other antibodies relating to stiff-person syndrome were negative. We diagnosed PERM and gave intravenous corticosteroids and immunoglobulins without benefit; however, following plasma exchange he has made a sustained improvement.

Coexistence of Takayasu Arteritis and Crohn's Disease in a Maltese Patient.

Takayasu arteritis (TA) and Crohn's disease (CD) are uncommon chronic granulomatous disorders affecting the large arteries and the gastrointestinal tract, respectively. At least 40 occurrences of these two conditions in the same patient have been reported in the literature, raising the possibility of an association between them. We report the coexistence of TA and CD in a young Maltese patient and review the literature to discuss possible aetiological mechanisms that might explain this association.
