Cauda equina compression presenting as spontaneous priapism.

Disturbance of autonomic function is an unusual feature of compression of the cauda equina. A 61 year old man who had complete occlusion of the lumbar spinal canal with compression of the cauda equina from a large centrally prolapsed disc, had spontaneous priapism, precipitated by walking and relieved by resting. This symptom was comparable to claudication by compression of cauda equina. It subsided completely after surgical removal of a prolapsed L4-5 disc.

"Grand mal type" of spike discharge as interseizure phenomenon.

Grand mal type of sequential spike discharges at 8-12 cps are rare as interseizure phenomena. When the grand mal component is prominent, it usually indicates a greater tendency for major convulsions. The case of a 15 year old girl who developed akinetic seizures along with her menarche and whose electroencephalogram showed recurring sharp waves at 10-11 cps, is reported, and its clinical significance discussed.

Focal cerebral dysrhythmia--presenting as headache: report of a case.

A 14 year old girl developed persistent headache of 6 weeks duration, which she described as a feeling of pressure, accompanied by dizziness, nausea and vomiting. Her EEG showed focal slow waves arising from the right temporo-occipital region. All other investigations were negative. Other medication was ineffective but she responded well to standard anticonvulsant therapy, and her EEG abnormality became minimal. In a case with focal slowing and pain and other handicapping symptoms, which do not respond to other remedies, a trial of antiepileptic medication is indicated even in the absence of clinical seizures and/or EEG evidence of seizure activity.

Toxic encephalopathy from chlorobenzilate poisoning: report of a case.

Chlorobenzilate is an organochlorine insecticide with toxicity like those of Dichlorodiphenyltrichloroethane (DDT). A patient who developed toxic encephalopathy after exposure to chlorobenzilate mist, with associated clinical and EEG abnormalities, is briefly reported. Some unusual features of his clinical picture are pointed out.

Single case study. Contact epilepsy: a rare form of reflex epilepsy.

An 80-year-old male is presented who had violent myoclonic seizures with occasional brief loss of consciousness, triggered by tactile stimuli directed to the upper extremities and upper part of the trunk which evolved over a 10-year period. Physical examination revealed very few neurological abnormalities. His resting electroencephalograms were normal, but generalized spikes, polyspikes, and slow wave discharges were precipitated by tactile stimuli with the patient sitting up. He showed no significant response to standard anticonvulsant therapy. The relevant literature is reviewed briefly.
