    Notes: Summary In order to examine otolithic contribution to eye movements ten subjects were asked to track either a moving acoustic target or a stationary target during subect linear motion on a cart. The relative displacement between the subject and the target was the same in the two situations. Recordings of eye movements during subject lateral acceleration in the dark without any task, or with the task of tracking an imagined stationary target were made as a control. The frequencies ranged between 0.15 and 0.3 Hz and peak acceleration between 0.55 and 1.2 m/s2. No lateral eye movements (L-nystagmus) were recorded in the dark. Only saccadic eye movements were recorded during the tracking of a moving acoustic target. Slow eye movements interspersed by saccades were observed when the moving subject tracked an imagined or an acoustic stationary target. Contribution of the slow phase to tracking was more important in the presence of an acoustic target than in the presence of imagined target. The results are interpreted in terms of an otolithic contribution to the central reconstruction of the acoustic target velocity, or in terms of an adaptive control of the otolithic-ocular reflex gain. A conceptual model accounting for these interpretations is proposed.

    Description / Table of Contents: Summary The subject of this report is a newborn female, suffering from hypotonia and breathing difficulties, delivered in the 37 week with the help of forceps. Because of the nature of her symptons and those of the mother, which included Facies myopathica and Myotonia, the possibility of the expansion of a CTG-Trinukleotidsequence in the area of Chromosom 19 was explored. For this purpose a technique, developed in 1992, for the identification of molecular genetic characteristics was used. Instead of the 5 to 27 copies of the CTG sequence normally found in the population, the sick child had 1000 and the mother more than 700. EMG, in which a classical relases of myotones (Fall-Fight-Bomberscream) were found, confirmed the neurological diagnosis. Discussion: In the course of time the newborn child showed the classical problems of hyptotonia, such as respiratory difficulties, eating disorders leading to a loss of weight, meteroism, and after another stay in hospital, symptoms of Ileus.
    Notes: Zusammenfassung Es wird über ein in der 37. SSW durch Forzeps geborenes Mädchen berichtet, das durch Hypotonie und Ateminsuffizienz auffiel. Diese Symptome, ebenso wie die Facies myopathica und die Myotonie der Hand der Mutter bei der Begrüßung, gaben den Hinweis zur Durchführung der seit 1992 möglichen molekulargenetischen Bestimmung der Expansion einer CTG-Trinukleotidsequenz im Bereich des Chromosoms 19. Statt der in der Normalbevölkerung 5–27 Kopien dieser CTG-Sequenz-Wiederholung fanden sich bei dem erkrankten Kind über 1000 und bei der Mutter über 700. Darüber hinaus konnte durch eine neurologische Untersuchung der Mutter die bisher unbekannte Diagnose bestätigt werden, wobei im EMG eine klassische myotone Entladung (Sturz-Kampf-Bomber-Geräusch) gefunden wurde. Diskussion: Beim Neugeborenen traten im weiteren Verlauf die klassischen Folgeprobleme der Hypotonie wie Respiratorbedürftigkeit und Ernährungsprobleme mit relativer Gewichtsabnahme, Meteorismus und bei einer erneuten stationären Aufnahme Ileussymptomatik auf.
