    Description / Table of Contents: Zusammenfassung Bei 23 Kindern mit primärer Hypothyreose, die mit Thyroxin (T4) und Trijodthyronin (T3) enthaltenden Kombinationspräparaten behandelt worden waren, wurden TRH-Teste, TBI, T3- und T4-Bestimmungen durchgeführt. Die T3/T4-Quotienten wurden berechnet. 7 von 10 Patienten mit TRH-refraktären TSH-Werten und normalen T4-Spiegeln wiesen überhöhte T3-Werte auf. Bei 6 von diesen Patienten konnten pathologisch überhöhte T3/T4-Quotienten beobachtet werden. Eine TRH-refraktäre TSH-Suppression wurde nur bei hohen T4-Werten gefunden. Nach einer Reduktion der Substitutionsdosis normalisierten sich die überhöhten T3-Spiegel. Die Befunde zeigen, daß nicht nur die T4-Werte sondern auch die TSH- und T3-Spiegeln unter der Behandlung mit Schilddrüsenhormonen kontrolliert werden sollten. Die Durchführung der Substitutionstherapie der Hypothyreose mit T3/T4-Kombinationspräparaten im Verhältnis 1:4 sollte überdacht werden.
    Notes: Summary TRH-tests, triiodothyronine (T3), TBI, and thyroxine (T4) determinations were carried out in 23 children with primary hypothyroidism treated with T3/T4-preparations. T3/T4 quotients were calculated. 7 out of 10 patients with TRH refractory TSH values and normal T4 levels had T3 values above normal range. In 6 of them pathologically elevated T3/T4 quotients could be observed. A TSH refractory TSH suppression was only found in patients with superior normal T4 values. After a reduction of the replacement doses the T3 values were normal. The findings show — that not only the T4 values should be controlled under treatment with thyroid preparations but also the T3 and TSH serum levels. The replacement therapy of hypothyroidism with T3/T4 preparations in proportion 1:4 should be revised.

    Notes: Summary 120 caloric vestibular tests (50 ml water of 30° resp. 44° in 30 s) were carried out on 30 normal persons 20—30 years of age. The responses were analyzed as to the reliability of evaluation using Frenzel's glasses, in case of a limited evaluation to a defined observation period. This observation period was located at different time-intervals after stimulation and compared to the maximal phase of reaction registered by ENG simultaneously. The difference between the number of beats within the fixed observation period and the number of beats within the maximal phase of reaction was defined as the rate of error. The interval (20, 50) s after the end of stimulation was highly qualified to present the intensity of the vestibular response. As some reactions are very slow and finished before the 20th s the interval (10, 70) s was suggested, too. The intervals (20,50) — and (10,70) s showed low rates of error and high correlation to the maximal reaction. This method can be used for clinical routine. Difficult problems can only be answered by more elaborate proceedings.
