Abstract. This case of ascending paralysis, following an episode diarrhea, was initially misinterpreted as Guillain-Barré syndrome. The prominent hypokalemia led to the search for other differential diagnoses, interpreted a rare periodic hypokalemic which usually occurs in Asians after intake large amounts starch foods, such Spaghetti, or rest heavy exercise. In this case, reason with associate...

primary hypokalemic periodic paralysis is a familial channelopathy inherited as an autosomal dominant trait. the first attack of paralysis may be evolved at any age, but has been reported to be most common in the second decade, so that some authorities believe that an episodic weakness beginning after age 25 is almost never due to primary periodic paralysis. in this retrospective study, we revi...

Thyrotoxic periodic paralysis (TPP) attacks are characterized as recurrent, transient episodes of muscle weakness that range from mild weakness to complete flaccid paralysis. Episodes of weakness are accompanied by hypokalemia, which left untreated can lead to life-threatening arrhythmias (6). In this case study, we followed a patient's potassium levels analyzing how they correlate with electro...

Thyrotoxic Periodic Paralysis (TPP) is a rare and life threatening condition commonly occurring in young Asian males. It is characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Serum potassium levels may be normal in rare cases of TPP. The diagnosis of normokalemic TPP may be overlooked and/or delayed in most cases. Here, we describe a 32-year-old Iranian...

We report the discovery of quasi-periodic oscillations (QPOs) at roughly 187 and 150 Hz in the X-ray intensity of X-ray nova XTE J1859+226. The source was observed during a recent outburst with the Rossi X-Ray Timing Explorer. Besides these high-frequency QPOs, we have also detected QPOs (and sometimes their harmonics) at 6-7 Hz and significant broadband variability at low frequencies. These pr...

A 30-year-old woman had scleroderma, Sjögren's syndrome, deforming polyarthritis, distal renal tubular acidosis, hypokalemic periodic paralysis, and persistent mild myopathy. During a five-year period the patient's otherwise mild course of disease was complicated by the occurrence of five episodes of severe flaccid muscle paralysis involving both proximal and distal muscle groups. Between the p...

Thyrotoxic hypokalemic periodic paralysis (TPP) is characterized by acute attacks of weakness, hypokalemia, and thyrotoxicosis of various etiologies. These transient attacks resemble those of patients with familial hypokalemic periodic paralysis (hypoKPP) and resolve with treatment of the underlying hyperthyroidism. Because of the phenotypic similarity of these conditions, we hypothesized that ...

Hypokalemic Periodic Paralysis (HypoPP) is a condition that causes episodes of extreme muscle weakness typically beginning in childhood or adolescence. The disorder three to four times more commonly clinically expressed men. Mutations the CACNA1S (calcium voltage-gated channel subunit alpha 1 S) SCN4A (sodium 4) gene can cause Paralysis. primary form genetic and follows an autosomal dominant pa...

Hereditary muscle channelopathies are caused by dominant mutations in the genes encoding for subunits of muscle voltage-gated ion channels. Point mutations on the human skeletal muscle Na+ channel (Nav1.4) give rise to hyperkalemic periodic paralysis, potassium aggravated myotonia, paramyotonia congenita and hypokalemic periodic paralysis type 2. Point mutations on the human skeletal muscle Ca2...
