Saccadic visual suppression and down-beat nystagmus: a case of Arnold-Chiari malformation.

A case is reported in which visual disturbances associated with the sole physical finding of downbeat nystagmus led to investigation of a patient for a foramen magnum lesion. The Arnold-Chiari malformation was suggested by air study and confirmed at surgery. It is suggested that the phenomenon of saccadic suppression was responsible for the patient's visual disability. This was unaccompanied by any of the other neurological manifestations of the Arnold-Chiari malformation. Cases presenting in this manner, with only visual disturbances, may run the risk of being unrecognized for some time as a result.

Posttraumatic dysautonomic cephalalgia. Clinical observations and treatment.

Five patients developed posttraumatic vascular headaches associated with autonomic dysfunction. The precipitating injury affected the anterior triangle of the neck, presumably involving the region of the carotid artery sheath. Disturbance of sympathetic function, characterized by excessive sweating and pupillary dilation associated with headache, was noted. Appropriate pharmacologic studies revealed evidence of partial sympathetic devervation. While headache was resistant to ergotamine preparations, prompt relief was obtained with propranolol hydrochloride, and adrenergic beta-receptor blocking agent.

Recovery from encephalomyelitis caused by Herpesvirus simiae. Report of a case.

A 29-year-old monkey handler developed an acute encephalomyelitis with neuromuscular dysfunction that progressed to respiratory arrest on the 18th day of illness. Thereafter, with supportive care, the patient's condition improved steadily. The titer of neutralizing antibodies to H simiae rose from 1:4 (eighth day of illness) to 1:512 (47th day of illness). Apparently the fifth known survivor of H simiae (herpesvirus B) encephalomyelitis, this patient is also remarkable because of virtually complete recovery, apparently the second documented instance of a good outcome.

Chemical epidural abscess: case report.

Spinal epidural abscess accompanies blood-borne infection, vertebral osteomyelitis, or an overlying cutaneous source of infection. This report documents the development of non-infective epidural abscess where the inflammatory response was induced by the highly irritant contents (keratin and cholesterol) of an underlying epidermoid. This was associated with aseptic meningitis.
