    Description / Table of Contents: Summary Two members of a family with Pyle's craniometaphyseal dysplasia are described. The urinary excretion of acid mucopolysaccharides was quantitatively normal. The disease is inherited as an autosomal dominant trait with rather wide intra-and interfamilial variability. A review of the literature disclosed an elevated number of consanguinous marriages suggesting an additional recessive mode of inheritance. The disease has primarily to be differentiated from osteopetrosis and progressive diaphyseal dysplasia.
    Notes: Zusammenfassung Klinisch-röntgenologische Darstellung einer Familie mit Pyle'scher Erkrankung. Die Mucopolysaccharidausscheidung war quantitativ normal. Die Erkrankung wird autosomal-dominant bei deutlicher Schwankung der familiären Expressivität vererbt. Gehäufte Verwandtenehen lassen an einen zusätzlich recessiven Erbgang denken, ohne diesen zu beweisen. Die Erkrankung ist in erster Linie von der Osteopetrose und von der progressiven diaphysären Dysplasie zu unterscheiden.

    Notes: Summary High frequency cinematographic films were made of the mode of operation of common oto-surgical drilling instruments on bone and cartilage. Rose bits and surgical fraises of different sizes were used at 5,000–80,000 R.P.M. The evaluation of the slow motion pictures was performed on the running films and by review of single frames. In detail: The preparation of the drilling head on the bone without simultaneous flushing leads to a filling of the cutting channel and decreased cutting. Drop flushing only prevents the increasing soiling of the drilling head if the drop sequence is rapid and which must be markedly increased with increasing R.P.M. of the drilling instrument. Flushing with a stream of water, which definitely prevents soiling, is preferable. Both drop flushing as well as the water stream must continuously wet the drilling head, i.e. must be absolutely centric in every case. Safest is the automatic spray flushing which is mounted on the handpiece, but which has so far not been used in otosurgery. During the preparation, the air space of the working area is always filled with drilling dust or haze. Cutting is always performed tangentially. The cutting speed lies between 2,9 m/s to 16 m/s. It depends on the R.P.M. of the drilling instrument. A drill head running out of true, even with a gently percussing shaft, touches the bone only with a part of its cutting surface which strikes more vigorously than desired and easily gets soiled, despite flushing. Cutting is therefore less and uncontrolled. An increased feeding energy (pressure on the support) in order to speed up cutting leads to heavy wear of the drilling instrument and unsafely in handling due to jumping of the drilling head. During each contact of a cutter with the bone, coarse fraises with low R.P.M. (5,000 R.P.M. =83 R/s) show a short stopping of the rotation which results in a jerk and vibration of the whole preparation and can thus lead to a damage of the inner ear.

    Notes: Summary In skull bone and septum cartilage holes were bored with rose trepans and diamond cutters of various sizes (2–20) and at different revolutions (5,000–42,000 rev/min) with and without the use of cooling fluid. The specimens were examined histologically. Borings with rose trepans without cooling fluid cause sometimes considerable heat lesions up to a depth of 30 μ. Bone shows the more severe lesions. The use of cooling fluid reduces the damage quite considerably (burns zone up to a maximum depth of 12 μ). In the normal range of up to 10,000 rev/min practically no heat lesions occur. In the high range above 20,000 rev/min the lesions are often only plaque-shaped. Water jet or spray cooling is superior to droplet cooling. Diamond cutters cause more severe lesions. Boring and grinding in the highest range (up to 300,000 rev/min) without cooling fluid cause very deep burns (up to 56 μ).

    Description / Table of Contents: Zusammenfassung Untersuchungen caber die Natrium- und Kaliumionenkonzentration im Speichel von Säuglingen rind spärlich, ihre Ergebnisse widersprüchlich. An 92 Säuglingen im Alter von 0–6 Monaten und 92 jungen Erwachsenen wurde die Natrium- und Kaliumionenkonzentration im simulierten, gemischten Nüchternspeichel bestimmt und statistisch ausgewertet. Sowohl die Natrium- als auch die Kaliumionenkonzentration lag im Speichel junger Säuglinge signifikant höher. Für die Natriumionenkonzentration betrug das geometrische Mittel im Säuglingsspeichel 587 mg/l, das der Erwachsenen lag bei 380 mg/1. Das geometrische Mittel der Kaliumionenkonzentration im Säuglings-speichel betrug 1757 ml/1, im Erwachsenenspeichel lag dieser Wert bei 1503 mg/l. Eine Deutung der Befunde wird versucht. 2 mögliche Ursachen werden diskutiert: 1. Das Speicheldrüsengewebe, insbesondere das Drüsengangsystem ist beim jungen Säugling nicht ausgereift. Es ist denkbar, daß es für Ionen permeabler wäre als im späteren Lebensabschnitt. 2. Das hormonelle System des Säuglings ist noch nicht funktionstüchtig. In Anlehnung an die Arbeiten von Rodeck über die Ursachen der Isosthenurie im frühen Säuglingsalter, die er auf eine mangelnde Reife des Zwischenhirn-Hypo physensystems und damit auf einen Mangel an Adiuretin zurückführen konnte, wird als Arbeitshypothese versucht, einen analogen hormonellen Mechanismus für die erhbhte Kationenkonzentration im Speichel junger Säuglinge anzunehmen.
    Notes: Summary Data on the concentration of sodium and potassium ions in the saliva of small infants are sparse, and results are far from uniform. The concentration of sodium and potassium ions was determined in the saliva obtained upon stimulation after fasting. Ninty-two infants, 0 to 6 months of age, and 92 young adults served as test subjects in this study. Statistically, the concentration of both sodium and potassium turned out to be significantly higher in the infants than in the adults. In particular, in the infant group, the lowest values for sodium varied between 100 mg/l and 200 mg/l and the highest ones between 2300 mg/l and 2400 mg/l, the geometric mean being 587 mg/1. In adults, the lowest values were 100–200 mg/1, but the highest only 1100–1200 mg/l, the geometric mean being not higher than 380 mg/1. With respect to potassium, the values did not differ that widely between the two groups. In infants, the lowest values were between 1300 mg/1 and 1400 mg/l, and the highest ones between 2800 mg/1 and 2900 mg/l, with a mean value of 1757 mg/l. In adults, the minimum values varied between 1000 to 1100 mg/l and the maximum values between 2900 to 3000 mg/1, with a mean value of 1502 mg/l. The demonstrated discrepancy may be accounted for by either of two causes: (1) In infants, the tissue of the salivary glands, especially the duct system, have not reached their final mature state. Therefore, the ion permeability of this tissue may be relatively high in early infancy. (2) The hormonal system is not fully developed in young infants. In his studies on the causes of iso-sthenuria in early infancy, Rodeck pointed to the incomplete development of the interbrain-hypophyseal system, and thus to the lack of Adiuretin, as a possible cause. A similar hormonal mechanism is assumed as the underlying cause for the increased concentration of cations found in the saliva of young infants as described in this paper.
