Prior to the introduction of lithium, mania was underdiagnosed in the U.S.A. Almost 50% of adults who met DSM-III criteria for mania had previously been diagnosed to have schizophrenia. To determine if mania had similarly been underdiagnosed in prepubertal children, 157 cases of 'severely disturbed' children described in the literature were reviewed. Approximately one-half (16/33) of the children diagnosed in this study as manic according to DSM-III had originally received another diagnosis. These results indicate that mania should be considered in the differential diagnosis of psychotic children, particularly those with affective symptoms.

Self-report vs. biological markers in assessment of childhood depression.

Sensitivity, specificity, and diagnostic confidence of the Children's Depression Inventory (CDI) and the dexamethasone suppression test (DST) in assessing childhood depression were determined. Parent and child forms of the CDI and plasma cortisol levels at 8 a.m. and 4 p.m. were used. Three groups of prepubertal children were sampled: (1) 63 depressed inpatients, (2) 14 non-depressed inpatient psychiatric controls, and (3) 21 normal community sample controls. Results suggest that scores greater than or equal to 15 on the CDI obtained from either parent or child provide a good screening instrument (sensitivity = 89%). If the DST is administered to all children with elevated CDI scores, diagnostic confidence is 97.5%. Cautions and recommendations for use of the CDI and DST are made.

Peripheral vascular disease in cigarette smokers and impaired hepatic metabolism of lipoprotein remnants.

The metabolism of very-low-density lipoproteins and chylomicrons includes the extrahepatic hydrolysis of their triglycerides by lipoprotein lipase. This results in cholesterol-rich "remnants" which are further metabolised by the liver. There is experimental evidence that in both patients with type-III hyperlipoproteinaemia and cigarette smokers hepatic-remnant metabolism may be depressed. In type-III hyperlipoproteinaemia the defect is inherited while in smokers it occurs in response to raised blood concentrations of carboxyhaemoglobin. The striking clinical similarity between type-III hyperlipoproteinaemic patients and smokers--namely, a high incidence of peripheral vascular disease--may be due to a common cause, the accumulation of cholesterol-rich remnants in the plasma.
