[Acute cyanide poisoning in an infant].
An infant of 9 months was admitted to hospital in comatose condition; cyanide poisoning was suspected. This poisoning was caused by the desorption of hydrocyanic acid from building materials after the house had been fumigated with hydrocyanic acid under strict supervision and observed safety measures. Administration of 4-dimethyl-aminophenol, a methaemoglobin inducer, and sodium thiosulphate together with supportive measures, led to complete recovery of the infant, although the general hypotony persisted for a few weeks.

Longisectional interaction structure analysis (LISA) in psychopharmacology and developmental psychopathology.
Longisectional interaction structure analysis (LISA) is a method for evaluating multivariate observations in a sample of individuals (patients) at two or more than two subsequent times (stages). It combines cross-sectional configural frequency analysis (CFA) for defining interactions between variables at a given stage with longitudinal interaction structure analysis (ISA) in relating variables observed at two subsequent stages, nonparametrically. The interactions are identified locally as types rather than globally as contingencies, where types are defined as (cross-sectional or longitudinal) patterns occurring in more individuals than expected under H0 of no (cross-sectional or longitudinal) interaction. LISA is applied to data sets from a clinical follow-up study and from a longitudinal study within developmental psychology. It is shown to be a useful technique for the interpretation of such data.

Overachievement and catecholamine excretion in an achievement-demanding situation.
We have studied the relationship between overachievement (defined as high school achievement in relation to intelligence) and catecholamine output (adrenaline and noradrenaline). The subjects were 176 children aged 13 yr. Adrenaline and noradrenaline excretions were measured in (1) a neutral situation (attending a nonexciting film), and (2) in an achievement-demanding situation. In the achievement-demanding situation, overachieving boys had much higher adrenaline excretion levels than the other boys. This difference was not found for girls. For boys, overachievement in combination with overambition (as rated by teachers) was related to a higher output of both adrenaline and noradrenaline in an achievement-demanding situation.

Type A behavior: a longitudinal study from childhood to adulthood.
In a longitudinal study of a sample of Swedish males and females (n = 170), Type A-related behavior at age 13 was related to the scores on an abbreviated Type A scale based on JAS which was administered when the same subjects were 27 years old. Aggression, Motor Hyperactivity, Overambition, and Overachievement measured at age 13 were used as predictors in a multiple regression analysis, with Type A score at age 27 as the dependent variable. The following results were obtained: 1) for men the multiple correlation was 0.41 (p less than 0.01), with Aggression and Overambition accounting for most of the prediction, and b) for women the multiple correlation was 0.36 (p less than 0.05), with Motor Hyperactivity accounting for most of the prediction. It was concluded that Type A-related behavior could be identified rather early and that it shows an unexpected degree of stability over a period of 14 years.
