Titin founder mutation is a common cause of myofibrillar myopathy with early respiratory failure.

Objective: Titin gene (TTN) mutations have been described in eight families with hereditary myopathy with early respiratory failure (HMERF). Some of the original patients had features resembling myofibrillar myopathy (MFM), arguing that TTN mutations could be a much more common cause of inherited muscle disease, especially in presence of early respiratory involvement.

Methods: We studied 127 undiagnosed patients with clinical presentation compatible with MFM.

Transient global amnesia in a patient with acute unilateral caudate nucleus ischemia.

The pathogenesis and localization of neuronal dysfunction in transient global amnesia (TGA) is still disputed more than 40 years after the first description of this clinical entity. Previous studies have indicated that structural abnormality is rare in TGA. We report a case of TGA in a patient with acute ischemia in the body of right caudate nucleus.
