OBJECTIVE To document a patient with periodic alternating nystagmus (PAN) caused by acute disseminated encephalomyelitis (ADEM) and suggest a mechanism to explain her PAN. PATIENT A 34-year-old woman with PAN caused by ADEM. INTERVENTION Diagnostic. RESULTS The patient complained of severe disequilibrium from the disease onset. Four years after onset,(More)
OBJECTIVE To describe the clinical course and treatment of a patient presenting with thrombophlebitis of the head and the neck with eosinophilic otitis media (EOM). PATIENT The patient was a 32-year-old woman with bronchial asthma and chronic sinusitis. She was treated for EOM, which presented as intractable otitis media with viscous effusion.(More)
This is the first report of objective tinnitus presenting as audible spontaneous otoacoustic emission in a patient with tuberous sclerosis. The tinnitus was loud, continuous, and high pitched: 7757.8 and 6257.8 Hz. The auditory system may be dysfunctional in patients with tuberous sclerosis. Possible causes of tinnitus in these patients are abnormal(More)
OBJECTIVE Pseudo-images of three-dimensional eye movements captured on an infrared video oculogram can be translated onto a rotational expression around axial vector. This provides a subject's Listing's plane, which moves according to the head's orientation relative to gravity. Optokinetically induced changes in the cognitive gravitational reference frame(More)
Listing's plane is a construction derived from eye position and reflects gravitational orientation. The cerebellum plays a key role in orienting and integrating sensory input concerning gravity from visual, vestibular and proprioceptive apparatuses. This suggests that the thickness of Listing's plane could serve as a novel parameter for evaluating the(More)
OBJECTIVE Three-dimensional analysis of video-oculograms can be used to calculate Listing plane for patients and experimental subjects. Listing plane reflects the head's orientation with respect to gravity, which suggests that the plane is derived from otolithic vestibular input, itself, or from a gravity-oriented internal model constructed through(More)
The external nasal dilator Breathe Right is a nonprescription disposable mechanical device worn over the bridge of the nose that supports the outer walls of the nasal vestibule to increase cross-sectional nasal valve area and enhance air flow through the nose. When worn, the device applies a gentle outward pull to the outside walls of the nasal vestibule(More)
