Delayed neurological deterioration following carbon monoxide poisoning: MRI findings.

We present two patients with delayed neurological deterioration following apparent recovery from carbon monoxide poisoning in whom magnetic resonance imaging showed abnormalities. In the first patient, cortical grey matter abnormalities were seen without white matter changes. Visual evoked potentials were, however, abnormal. In the second, diffuse white matter lesions were detected. In neither patient were basal ganglia lesions seen.

Visuo-motor skill and visual perception in left and right handed children of superior intelligence.

It was thought possible that the proximity of the right parietal cortex to the leading hand area in left handed subjects may confer an advantage in tasks requiring visuo-motor function. However, the study showed the left handed group to be defective in the performance of the Wechsler Block-design Sub-test. As some mature left handed individuals may excel in tasks requiring refined visuo-motor skill, it is suggested that any constitutional deficiency is not fixed, but may be expected to disappear with increased maturity, or as the result of training.

Chlormethiazole in status epilepticus--three cases.

Despite the use of barbiturates, phenytoin sodium and diazepam given intravenously, status epilepticus continued in the three cases described until chlormethizaole (Heminevrin) was administered, when rapid resolution of the status occurred.

Sequelae to pneumoencephalography.

Fifty patients were examined clinically and neurologically for seven days after pneumoencephalography. Headache was present in 78%, neck stiffness in 34%, pyrexia in 38%, vomiting in 34%, tachycardia in 74%, a change in the level of consciousness in 18%, and abnormal neurological signs in 30%. Of the 13 patients with epilepsy, there was an increased frequency of seizures in four, associated with increased EEG epileptiform activity in three. EEG abnormality either appeared or increased in 74% of cases on the second day after the air study. A mechanism for the production of these sequelae is proposed. It is concluded that these findings indicate that in most cases an organic brain syndrome follows pneumoencephalography.
