Reactivation of hepatitis B virus (HBV) is one of the most worrisome side effects in patients with HBV infection receiving anti-TNF-α.

[Hemiballism-hemichorea with non-ketotic hyperglycemia: movement disorder related to diabetes mellitus].

Diabetes mellitus, especially when not under control, can lead to several neurological complications being the development of involuntary movements one of the rarest presentations. Nonketotic hyperglycemia in aged patients who present with ballismus-chorea movements and cerebral image alterations in computerized tomography (CT) and magnetic resonance constitute a syndrome of recent characterization and few cases in literature. We present a case of a 75 year-old male patient admitted with history of hemiballismus-hemichorea movements, hyperglycemia, glycated hemoglobin of 14.
