Hyperkalemic periodic paralysis and permanent weakness: 3-T MR imaging depicts intracellular 23Na overload--initial results.
PURPOSE To assess whether myoplasmic ionic sodium (Na+) is increased in muscles of patients with hyperkalemic periodic paralysis (HyperPP) with 3-T sodium 23 (23Na) magnetic resonance (MR) imaging and to evaluate the effect of medical treatment on sodium-induced muscle edema. MATERIALS AND METHODS This study received institutional review board approval; written informed consent was obtained. ...
متن کاملHyperkalemic Periodic Paralysis Synonym: HyperPP
Hyperkalemic periodic paralysis (hyperPP) is characterized by attacks of flaccid limb weakness (which may also include weakness of the muscles of the eyes, throat, and trunk), hyperkalemia (serum potassium concentration >5 mmol/L) or an increase of serum potassium concentration of at least 1.5 mmol/L during an attack of weakness and/or provoking/worsening of an attack by oral potassium intake, ...

متن کاملAcute generalized weakness due to thyrotoxic periodic paralysis.
T periodic paralysis (TPP) is a disorder characterized by thyrotoxicosis, hypokalemia and predominantly proximal lower limb paralysis. Despite the female predominance of hyperthyroidism, TPP occurs most frequently in males in a ratio of 20:1, and 90% of patients are of Asian descent. Prodromal symptoms may consist of muscle stiffness or cramping. Sensation, as well as bulbar and respiratory mus...
متن کاملAcetazolamide-induced muscle weakness in hypokalemic periodic paralysis.
A 46-year-old man with hypokalemic periodic paralysis (HypoPP) and diabetes mellitus (DM) had worsened muscle weakness after acetazolamide (ACZ) treatment. During the paralytic episode, serum potassium levels were reduced, and serum chloride and insulin levels were increased. The data suggested proximal renal tubular acidosis due to ACZ. We determined arterial-venous concentrations of potassium...
