    Description / Table of Contents: Zusammenfassung Die retrospektive Analyse von 7016 Schilddrüsenoperationen der Jahre 1978–1985 zeigte eine Zunahme der Operationsindikation „kalter Knoten” von 23 % auf 52 %. Die Malignitätsrate des kalten Knotens" nahm in diesem Zeitraum von 7,2 % auf 6,3 % ab. Die forcierte Operation des kalten Knotens brachte aber eine Zunahme der niedrigen Tumorstadien 1 und 11, wodurch Radikaloperationen im höheren Maße (68,3 %) möglich waren. Eine erhöhte Malignitätsrate zeigt ein kalter Knoten bei folgenden Risikofaktoren: solitärer, solider Knoten, Patient jünger als 30 Jahre, älter als 60 Jahre, männlichen Geschlechtes.
    Notes: Summary The retrospective analysis of 7016 operations of the thyroid (1978–1985) showed an increase of operations of cold nodules from 23 % to 52 %. The rate of malignancy of cold nodules decreased from 7.2 % to 6.3 %. But, the intensive operative management of cold nodules resulted in an increase of operations of low stage tumors. Therefore radical operation of thyroid tumors was possible in 68.3 % of cases. An elevated rate of malignancy is observed, if a cold nodule is associated with the following criteria: solitary, solid, male patients, younger than 30 and older than 60 years.

    Notes: Macrocyclic Arsinous Acid Ester. IVThe three-valent arsenic atom is a Lewis-acid, which formes inter- or intramolecular adducts. The reaction with aminoalcoholes and diols, described in this paper, leads to the formation of cyclic and non-cyclic arsinous acid esters (3, 5, 6, 7, 9, 10, 12, 13, 15, 16, 18), some of them containing a N→As-donor-bond.
