An unusual presentation of Huntington's disease.

We describe the case of a 59-year-old woman who exhibited psychotic symptoms, cognitive dysfunction, and restlessness. While the clinical picture and 18F-FDG PET/CT suggested the presence of a tauopathy, especially frontotemporal dementia or progressive supranuclear palsy, genetic testing eventually revealed Huntington's disease.

A case series of serious and unexpected adverse drug reactions under treatment with cariprazine.

Reporting of new or unexpected adverse drug reactions of medicines that are subject to additional monitoring ("black triangle" label), such as the antipsychotic drug cariprazine, is of paramount importance to improve pharmacotherapy safety.

Look-alikes, sound-alikes: Three cases of insidious medication errors.

Physicians should be aware of look-alike/sound-alike (LASA) drug names. Clearly legible drug prescriptions, preferably via electronic drug prescription systems, and the use of Tall Man lettering may help to prevent LASA medication errors.

Naltrexone-induced drug eruption.

Treatment of alcohol dependence with oral naltrexone may elicit an urticarial rash and angioedema. Acute spontaneous urticaria and an allergic reaction to an excipient represent important differential diagnoses.

Effects of levodopa/carbidopa intestinal gel versus oral levodopa/carbidopa on B vitamin levels and neuropathy.

Objectives: To determine the possible interactions between levodopa therapy and plasma levels of B vitamins in patients with advanced idiopathic Parkinson's disease (IPD) in the context of either oral levodopa therapy or levodopa/carbidopa intestinal gel (LCIG). Secondly, to determine the prevalence of neuropathy and its relation to plasma levels of B vitamins and homocysteine.

Methods: Medication doses, neurographies, and serum levels of pyridoxine, cobalamin, folate, and homocysteine of eight LCIG and 13 orally treated advanced IPD patients matched for age, Hoehn & Yahr stage, and UPRDS III were collected.
