A patient presented with typical polymyositis, but also with hypokalemia. Correction of potassium deficit without corticosteroids led to complete resolution of symptoms and laboratory abnormalities. Muscle biopsy performed after correction of the hypokalemia revealed focal fiber necrosis with
BACKGROUND
Polymyositis with cranial neuropathy has been rarely reported.
METHODS
We describe here three cases of polymyositis with trigeminal or facial neuropathy. Patients had muscular weakness, myalgia, rhabdomyolysis, endomysial infiltration with necrosis and regeneration at biopsy of muscle
The SK3 channel, a small-conductance calcium-activated potassium channel, is expressed in immature fibers of skeletal muscle and becomes down regulated after innervation. We have previously shown that the level of mRNA of the SK3 channel is increased in muscle from myotonic dystrophy. In this study,
Sera from patients with myasthenia gravis (MG) were screened for autoantibodies to skeletal muscle-specific antigens by immunoprecipitation assay, using rhabdomyosarcoma and leukemia cell lines. Eleven of 61 MG sera immunoprecipitated a rhabdomyosarcoma-specific 70-kDa protein, which was identified
The author presents the chronological development of therapy by corticosteroids in myasthenia gravis (MG), as well as dilemmas connected to this kind of treatment at the Centre/Institute Zagreb, she founded. The improvement of postoperative prognosis of thymectomy with corticosteroids is described
Duchenne muscular dystrophy, the most common childhood-onset muscular dystrophy, is X-linked and is associated with cardiac and mental abnormalities. Becker's muscular dystrophy is similar to but milder than Duchenne muscular dystrophy. The rare facioscapulohumeral muscular dystrophy has an
Primary aldosteronism (PA) is a rare disorder. The majority of patients with PA present with typical features and are easily diagnosed. This disorder is usually diagnosed with hypokalemia, hypertension or an adrenal mass. However, patients with atypical symptoms may present a challenge for diagnosis
