    Notes: Summary In a group of patients with idiopathic hypercalciuria and an increased fasting urinary calcium excretion we re-examined the question: does secondary hyperparathyroididsm exist? Eight out of 51 patients with calcium renal stones had a high calcium excretion in both fasting and in 24 h urines. The carboxyl-terminal immunoreactive PTH (iPTH) values in these patients were 16±5 ngeq/ml (M±SD), no higher than the iPTH values in the other groups, e.g. normocalciuric patients had an iPTH of 23±8 ngeq/ml. The existence of secondary hyperparathyroidism in a subgroup of stone patients with increased fasting urinary calcium excretion is questionable.

    Description / Table of Contents: Summary We measured the concentrations of serum calcium and 25-hydroxy-vitamin D in a patient with hypervitaminosis D during 3 months of therapy directed toward correcting the hypercalcemia. Serum calcium could not be maintained at normal concentration without specific therapy until 9 weeks after vitamin D was discontinued. Concentration of 25-hydroxy-vitamin D at the time was 285 ng/ml, approximately half of the value measured three weeks after withdrawal of vitamin D. Serial measurements of the concentration of 25-hydroxy-vitamin D seem to be a useful means of assessing the degree of intoxication in patients with hypervitaminosis D.
    Notes: Zusammenfassung Wir verfolgten die 25-Hydroxy-Vitamin D- und Calciumspiegel im Serum einer Patientin mit Vitamin D-Überdosierung unter calciumsenkender Therapie über drei Monate. Normale Serumcalciumspiegel fanden sich in einem therapiefreien Intervall erst 9 Wochen nach Beendigung der Vitamin D-Einnahme. Der 25-Hydroxy-Vitamin D-Spiegel lag zu diesem Zeitpunkt mit 285 ng/ml fast um die Hälfte niedriger als zu Beginn der Beobachtungszeit drei Wochen nach Absetzen des Vitamin D. Verlaufskontrollen der 25-Hydroxy-Vitamin D-Spiegel sind offenbar geeignet, das Ausmaß einer Vitamin D-Intoxikation abzuschätzen.

    Description / Table of Contents: Zusammenfassung Speichelelektrolyte (Natrium, Kalium, Calcium) wurden bei 10 mit Herzglykosiden und Spironolactone behandelten Patienten bestimmt. Bei zwei Patienten lag eine Digitalisintoxikation vor. Zwischen Speichelelektrolyten und Serumdigoxinkonzentration wurde, sowohl bei erhöhter als auch bei nicht erhöhter Aldosteronausscheidung im Urin eine gute Korrelation festgestellt. Aufgrund unserer Befunde ist zu vermuten, daß die durch Herzglykosidbehandlung hervorgerufenen Speichelelektrolytveränderungen unabhängig sind von einem gleichzeitig bestehenden sekundären Aldosteronismus und einer Spironolactonetherapie.
    Notes: Summary Salivary electrolytes (sodium, potassium, calcium) were measured in 10 digitalis-treated patients receiving spironolactone. Two of them could be identified as digitalis-intoxicated. The results showed good correlation with digoxin concentration in serum irrespective of whether aldosterone excretion was increased or not. This leads to the suggestion that the salivary electrolyte changes effected by digitalis treatment are independent from secondary aldosteronism and spironolactone therapy.

    Notes: Abstract Although several theoretical models posit that low levels of anxiety are a risk factor for psychopathy and antisocial behavior, a number of studies have reported elevated levels of anxiety among antisocial individuals. Nevertheless, most investigators in this literature have not distinguished between fearfulness and trait anxiety or attempted to separate the antisocial lifestyle dimension from the callous and unemotional dimension of psychopathy. In a study of clinically referred children (N = 143), we found that (a) measures of trait anxiety and fearlessness (low fearfulness) exhibited low correlations; (b) conduct problems tended to be positively correlated with trait anxiety, whereas callous and unemotional traits tended to be negatively correlated with trait anxiety; and (c) controlling statistically for the effects of one dimension increased the divergent correlations of the other dimension with both trait anxiety and fearful inhibition. These findings bear potentially important implications for the diagnosis and etiology of psychopathy and antisocial behavior and suggest that distinctions between trait anxiety and fearful inhibition, as well as between the two dimensions of psychopathy, may help to clarify longstanding confusion in this literature.
