Miller Fisher Syndrome: A Case Report Highlighting Heterogeneity of Clinical Features and Focused Differential Diagnosis.

Miller Fisher Syndrome (MFS) is a rare variant of Guillain-Barré Syndrome (GBS) that has a geographically variable incidence. It is largely a clinical diagnosis based on the cardinal clinical features of ataxia, areflexia, and opthalmoplegia, however, other neurological signs and symptoms may also be present. Serological confirmation with the anti-GQ1b antibody is available and allows for greater diagnostic certainty in the face of confounding symptoms.

Inclusion body myositis: a case of bilateral extremity weakness.

Inflammatory myopathy is a common cause of bilateral muscular weakness in adults. Although not as common as polymyositis, inclusion body myositis (IBM) is a form of inflammatory myopathy characterized by chronic progressive muscle inflammation and often goes undiagnosed and untreated. IBM patients most commonly present with proximal lower extremity weakness and may have normal creatine kinase (CK) levels.
