I report a case of a 33-year-old Caucasian man who presented with sudden onset paralysis, following previous similar presentations without investigation. Blood tests revealed undetectable serum potassium levels in the context of paralysis. [ncbi.nlm.nih.gov]

• Xerostomia

  The patient, who had no xerostomia and xerophthalmia, was diagnosed with primary SS from serologic and histologic findings of minor salivary gland biopsy. The patient recovered after potassium replacement therapy. [ncbi.nlm.nih.gov]

• Onset at Age <20

  […] before age 20 years. [ncbi.nlm.nih.gov]

The patient was admitted to the intensive care unit where further workup revealed thyrotoxicosis and the patient was subsequently diagnosed with TPP. [ncbi.nlm.nih.gov]

An association with thyroid disease is well established and further workup revealed Grave's disease in this patient. [casesjournal.biomedcentral.com]

Treatment includes the supplementation of potassium, a nonselective beta-blocker, and ultimately treatment of the underlying hyperthyroidism. [ncbi.nlm.nih.gov]

OBJECTIVE: This review emphasizes the etiology, pathogenesis, management and prognosis of TPP and aims to highlight clinical awareness of early diagnosis and rapid initiation of treatment. [ncbi.nlm.nih.gov]

Antenatal diagnosis Prenatal diagnosis is theoretically possible if the disease-causing mutation in the family has been identified but is rarely performed because of the non life-threatening prognosis. [orpha.net]

Prognosis [ edit ] The prognosis for periodic paralysis varies. [en.wikipedia.org]

Prognosis Most patients learn to prevent their attacks well enough that no significant deterioration in the quality of life occurs. Strenuous exercise must be avoided, however. Attacks often lessen in severity and frequency during middle age. [encyclopedia.com]

The etiology of these abnormalities and the patient's symptoms was found to be undiagnosed and uncontrolled hyperthyroidism from Grave's disease, which resulted in this dramatic presentation of thyrotoxic hypokalemic paralysis. [ncbi.nlm.nih.gov]

Summary Epidemiology Prevalence is estimated at around 1 in 100,000. Clinical description The paralysis most often affects the four limbs, thus resulting in tetraplegia. [orpha.net]

Epidemiology There are primary and secondary forms. The primary form is genetic and follows an autosomal dominant pattern of inheritance. [unboundmedicine.com]

Epidemiology Hypokalaemic periodic paralysis (HOKPP) has a prevalence of 1 case per 100,000 population. [patient.info]

Here we report three cases of TPP in the Netherlands, and review the literature on clinical features, pathophysiological hypothesis and treatment. [ncbi.nlm.nih.gov]

Overview This article on periodic paralysis and related disorders introduces readers to the clinical presentations, basic concepts, and current understanding of the pathophysiology of these rare disorders or channelopathies. [medlink.com]

Prevention There is no way to prevent the occurrence of either disease in a person with the gene for the disease. [encyclopedia.com]

Taking potassium supplements may help prevent muscle weakness. Eating a low-carbohydrate diet may help decrease symptoms. A medicine called acetazolamide may be prescribed to prevent attacks. [nlm.nih.gov]

As we see, acetazolamide prevents attacks in many cases. [flipper.diff.org]

Episodes can be prevented by achieving a euthyroid state. This report describes a young gentleman presenting with thyrotoxic hypokalemic paraparesis. [ncbi.nlm.nih.gov]
