Cerebral arachnoid cysts in children.

The case histories of 14 children are described in which hydrocephalus was found on investigation to be associated with a cyst of the posterior fossa or subarachnoid cisterns. The neuroradiological and histological findings are described. The cysts are considered to be developmental in origin. Their recognition and management are discussed.

Subclinical neuropathy in lead workers.

Evidence is presented for a minimal defect of peripheral nerve function in a group of lead accumulator workers without clinical evidence of a neurological lesion. Of the 19 men examined, 13 had blood levels above 80 mug./100 ml. and seven had haemoglobin levels below 12 g./100 ml., showing that considerable exposure to lead was occurring.

Results of anterior transposition of the ulnar nerve for ulnar neuritis.

A clinical and electrophysiological followup study was done on 23 patients with ulnar neuritis treated by surgical transposition of the nerve at the elbow. Pain was relieved in all those affected and other sensory symptoms showed some degree of improvement in most. Weakness tended to persist, but recovery of full use of the hand followed operation in 74%. Muscle wasting was the least likely to improve. The chance of recovery after operation was greatly reduced in patients in whom preoperative symptoms had been present for more than one year.

Involuntary movements in patients taking oral contraceptives.

Involuntary movements developed in five women taking oral contraceptives. In one, the sudden onset of a unilateral disturbance suggested a cerebral thrombosis; this case is considered to be a further example of the increased risk of cerebrovascular disease associated with oral contraception. The four other patients suffered a relapse of Sydenham's chorea between one and four months after starting an oral contraceptive regimen. Possibly an underlying vascular mechanism was responsible for these relapses.
