[A case of Churg-Strauss syndrome with elevated IgG4--the association between treatment and IgG4].

We report the case of a 57-year-old woman, known to have had allergic sinusitis and bronchial asthma, and had been treated with leukotriene receptor antagonist for one month, at the time of presentation. She complained of bilateral weakness and pain in her lower extremities and her laboratory investigations revealed an elevated absolute eosinophil count of 23,357/μl, elevated biliary enzymes and an IgG4 level of 594 mg/dl. Nerve conduction study revealed mononeuritis multiplex.

Repetitive transcranial magnetic stimulation alters optic flow perception.

Optic flow, the visual motion radiating from the center to side or opposite directions, is used to control human locomotion. Low-frequency repetitive transcranial magnetic stimulation (0.9 Hz, 10 min) was applied to the primary visual cortex (V1) and the extrastriate area (V5/MT) of 12 healthy participants to study effects of repetitive transcranial magnetic stimulation on coherent optic flow perception.

EEG findings in early-stage corticobasal degeneration and progressive supranuclear palsy: a retrospective study and literature review.

Objective: Although neuroimaging and electrophysiological tests are potentially useful to distinguish corticobasal degeneration (CBD) from progressive supranuclear palsy (PSP), little is known about the diagnostic value of electroencephalography (EEG) for their distinction. We assessed the value of EEG for differentiating CBD from PSP.

Methods: We reviewed conventional EEGs recorded at an early stage of disease in 10 CBD patients and 14 PSP patients.

[Fibromuscular dysplasia of the basilar artery presenting as cerebral infarction in a young female].

We reported a 20-year-old woman with fibromuscular dysplasia (FMD) of the basilar artery presenting multiple cerebral infarctions. A sudden onset of consciousness disturbance and right hemiparesis was experienced. A neurological examination on day 2 revealed an absence of light and corneal reflexes on the left side, homonymous left upper quadrant anopsia and right hemiparesis with Babinski sign: she was also somnolent.

Exacerbation of chronic inflammatory demyelinating polyradiculoneuropathy during interferonbeta-1b therapy in a patient with childhood-onset multiple sclerosis.

Interferonbeta-1b (IFNbeta-1b) is commonly used for relapsing-remitting multiple sclerosis (MS). We report a 23-year-old woman with childhood onset relapsing-remitting MS treated with IFNbeta-1b who developed overt chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) immediately after therapy. A baseline conduction study before IFNbeta-1b therapy revealed decreased motor conduction velocities and prolonged F wave latencies in several nerves, but there was no neurological sign indicating neuropathy.
