In order to clarify relationships among four dimensions thought to underlie schizophrenia, 52 patients were rated on a scale of premorbid personality and on a scale measuring the process-reactive dimension. They were further categorized with respect to chronicity and the presence of paranoia. Results indicated that the process-reactive, good-poor premorbid personality, and acutechronic dimensions are essentially similar; and that the paranoid-nonparanoid dimension is independent of the others. Testing on a double alternation learning task demonstrated differences between paranoids and nonparanoids, but not between the poles of the other dimensions.

In a clinical comparative study, 49 patients were treated for the tremulous and agitated states and acute hallucinosis of alcohol withdrawal. Thirteen patients were treated with promazine hydrochloride, and 12 each with paraldehyde and chloral hydrate, alcohol, or chlordiazepoxide hydrochloride. Of these therapies, paraldehyde with chloral hydrate was most effective and best tolerated. Twenty-three patients were treated for delirium tremens. Twelve were treated with promazine and suffered numerous complications, including death in two cases. Eleven were treated with paraldehyde and chloral hydrate with prompt clearing of hallucinations; there were no failures and only one complication (transient fever).From the Wood (Wis) Veterans Administration
