Skeletal Myopathy as the Initial Manifestation of Light Chain Multiple Myeloma.

Unlabelled: Monoclonal gammopathies due to plasma cell dyscrasias can cause various rare neuromuscular disorders. The peripheral nervous system is most commonly affected, while muscle diseases associated with monoclonal gammopathies are rare. Skeletal myopathy, as a manifestation in the context of multiple myeloma, is extremely uncommon and is usually the result of immunoglobulin light chain (AL) amyloidosis deposits in the muscles.

[Primary Sjögren's syndrome and neuromyelitis optica].

Neuromyelitis optica (NMO) is characterized by the association of optic neuritis and myelitis without any other neurological signs. In 30 % of the cases, NMO is associated with a systemic disorders. We report two cases of NMO associated with primary Sjögren's syndrome that was diagnosed during an acute flare of NMO.

[Celiac disease and ischemic stroke].

Introduction: Neurological manifestations of celiac disease are various. An association with ischemic stroke is not common and has not been well documented. We report two cases.

Introduction: Several extra-intestinal manifestations of inflammatory bowel disease have been reported, although reports of neurologic disorders are rare.

Case Reports: We report two cases of peripheral and central neurological manifestations of inflammatory bowel disease. The first case is a 33-year-old woman who developed acute inflammatory demyelinating motor polyneuropathy in association with Crohn's disease.
