A [(18)F]-FDG PET study was performed in a 44 year old man with proximal kinesigenic choreoathetosis (PKC) secondary to idiopathic primary hypoparathyroidism (IPH) before and 1 year after calcium/calcitriol therapy. The [(18)F]-FDG PET performed before the start of the therapy disclosed a significant bilateral hypometabolism in the ventral striatum. One year later, with the patient still under ...

chorea is brief, quasi-purposeful, irregular muscle contractions, not repetitive or rhythmic, but flows from one muscle to the next and athetosis is slow, writhing, continuous, worm-like movements of distal extremities (chiefly the fingers) which show bizarre positioning without posturing. metabolic causes have been documented earlier, note worthy of that being diabetes. choreoathetosis has bee...

Dra. Mariana Spitz – Rua Paulo César de Andrade 200/402 22221-090 Rio de Janeiro RJ Brasil. E-mail: [email protected] Firearm projectiles have been described, albeit rarely, as a cause of lead toxicity.

BACKGROUND Dihydroartemisinin-piperaquine is a combination of dihydroartemisinin and piperaquine which is highly effective in the treatment of uncomplicated falciparum malaria. Its adverse effects are generally tolerable and temporary. Choreoathetosis, an involuntary movement disorder characterized by continuous irregular twisting of the body, is not a documented adverse effect of this medicati...

A case of paroxysmal kinesigenic choreoathetosis is described. A hitherto unreported response to l-dopa is recorded and its possible relevance to the pathophysiology of the disorder is discussed.
