A crisis triage rating scale. Brief dispositional assessment of patients at risk for hospitalization.

The authors have developed a brief rating scale to expedite the rapid screening of emergency psychiatric patients who require hospital admission from those who are suitable for outpatient crisis intervention treatment. The interviewers used this scale to assess and score the patient rapidly on the basis of three factors: dangerousness, support system, and motivation or ability to cooperate. The authors report on and discuss the use of the scale in a preliminary study of 300 cases and in a prospective study of 122 patients who were followed for 6 months after they were evaluated. They found that those who scored below a median point on the scale required hospitalization and those who scored higher were suitable for crisis intervention as outpatients.

A comparison of hepatic adenylosuccinate lyase from rats fed either a chow diet or a semisynthetic basal diet low in riboflavin.

1. AMPS Lyase which shows increased activity in both transplantable and primary hepatomas has been purified approximately 400-fold from both chow fed and basal fed rat liver. 2. The enzyme from basal fed rats shows subtle but significant differences from the enzyme from chow fed rats. Especially noted was the difference in effect of 100 mM Na+ on the enzyme from the two different sources after the whole liver had been frozen. 3. These differences may be related to the effects of starvation followed by refeeding or administration of either glucose or corn oil.

Effect of hepatocarcinogens on the adenine purine nucleotide cycle during the initiation phase of carcinogenesis.

Activities of the adenine purine nucleotide cycle enzymes, i.e., adenylosuccinate (SAMP) synthetase, SAMP lyase, and adenosine 5'-monophosphate deaminse, were determined in hepatic tissue of rats fed and/or given injections of 3'-methyl-4-dimethylaminoazobenzene, 4'-methyl-4-dimethylaminoazobenzene, thioacetamide, ethionine, or 2-acetylaminofluorene. SAMP lyase activity showed an early increase in all regimens containing hepatocarcinogens. Adenosine 5'-monophosphate deaminse showed increases with 3'-methyl-4-dimethylaminoazobenzene and thioacetamide but not with ethionine or 2-acetylaminofluorene. SAMP synthetase either was nonresponsive or else showed inhibition to the carcinogens. Increase in SAMP lyase activity was noted as early as 48 to 72 hr following i.p. injections of these carcinogens. The response of SAMP lyase was not duplicated by analogs of carcinogens such as 4'-methyl-4-dimethylaminoazobenzene or methionine. These data imply interaction of active carcinogens with SAMP lyase and to some extent adenosine 5'-monophosphate deaminse or to some mechanism responsible for their synthesis and/or release. This interaction may be a significant component of the initiation phase of carcinogenesis.

Ulnar nerve palsy in Paget's disease.

A 73-year-old housewife with enlargement of her distal right humerus and especially the medial epicondyle due to Paget's disease developed an ulnar nerve palsy. Transposition of her ulnar nerve anterior to her elbow completely relieved her symptoms. A similar case of ulnar nerve palsy associated with expansion of the distal humerus due to Paget's disease seems not to have been previously reported.
