Dermatomyositis

A type of idiopathic inflammatory myopathy characterized by evocative skin lesions and symmetrical proximal muscle weakness.

Syncope refers to a generalized weakness of muscles with loss of postural tone, inability to stand upright, and loss of consciousness. Once the patient is in a horizontal position, blood flow to the brain is no longer hindered by gravitation and consciousness is regained. Unconsciousness usually lasts for seconds to minutes. Headache and drowsiness (which usually follow seizures) do not follow a syncopal attack. Syncope results from a sudden impairment of brain metabolism usually due to a reduction in cerebral blood flow.

	Restrictive cardiomyopathy in dermatomyositis.
	Finsterer J, Stollberger C, Avanzini M, Rauschka H. Scand J Rheumatol. 2006;35(3):229-32.
	In a 78-year-old male with a history of arterial hypertension, recurrent episodes of atrial fibrillation and syncopes, rupture of an infra-renal aortic aneurysm with complications (recurrent QT-prolongation, lumbo-sacral plexopathy, transient ischaemic attack, peripheral embolism), monoclonal gammopathy, subdural haematoma, focal seizures, megaloblastic anaemia, leucopenia, eosinophilia, elevated muscle enzymes and increasing tiredness, dermatomyositis was diagnosed upon clinical presentation, muscle enzyme and muscle biopsy findings.
