Clinical features of hemichoreahemiballism: A stroke-related movement disorder.

We examined pathogenesis and clinical features of three hemichorea-hemiballism (HCHB) cases. We studied their age, magnetic resonance imaging results, vascular risk factors, management, and outcomes. One man and two women (aged 74-86 years) demonstrated acute onset of HCHB, lasting for at least several months.

Clinical features of drug-induced Parkinsonism.

Drug-induced Parkinsonism is often reversible after withdrawal of the causative drug. Its clinical course, however, is not well understood, as the majority of cases are caused by drugs prescribed by departments outside of neurology. We reviewed 21 cases of drug-induced parkinsonism for several factors, including age, sex, causative drug and reason for prescription, department by which it was prescribed, and outcome.

Electroacupuncture Therapy for Auricular Paresthesia.

The great auricular nerve (GAN) provides sensory innervation to the skin around the auricle. Although disorder of this nerve has been reported, great auricular neuralgia, as reported by Blumenthal in 1992, is uncommon. The authors report a case of auricular paresthesia that responded well to electroacupuncture treatment (EAT).

[A case of complex partial seizure with reversible MRI abnormalities in the elderly].

A 79-year-old woman was admitted to our hospital because of prolonged impaired consciousness and right hemiparesis. She was treated for acute cerebral infarction because her brain magnetic resonance imaging showed extensive cortical lesions similar to acute infarction in diffusion weighted image, fluid attenuated inversion recovery, and T2 weighted images. On the fifth day, she had a focal seizure on the right side.

[A case of acute disseminated encephalomyelitis (ADEM) associated with peripheral neuropathy].

A 17-year-old boy with high fever, headache, and neck stiffness was admitted to our hospital. Spinal fluid showed a protein level of 215 mg/dL with myelin basic protein (579 pg/mL), 347/ microl cells (330 mononuclear cells), and a glucose level of 53 mg/dL. One week later, urinary retention, flaccid paraplegia, and sensory disturbance below the 10th thoracic level developed.
