[Dysgnathias and apical S-sound formation].

From 800 patients with dysgnathias and from 90 probands with eugnathic bite those persons were selected, who had no sigmatism. The position of the tongue during the articulation of the sound S was proved at persons without sigmatism. Sigmatism is observed as highly significant more frequently at patients with dysgnathias than at probands with eugnathic bite. An apical kind of formation of the sound S is observed as significant more frequently at patients with dysgnathias than at persons without dysgnathias. Apical S is found as highly significant more frequently at the "open bite" than at the "lack of room" and at the "extended overjet". Apical S especially together with dysgnathias may be valued as a transition to a pathologic sound S.

[Relationships between dysgnathias, mode of formation of the sound S and abnormal deglutition].

In this study it is tried to clear how much there exist correlations between sigmatisms and abnormal deglutition of patients with dysgnathias. It was found of 535 patients of an orthodontic department that abnormal swallowing of patients with dysgnathias having a sigmatism with a probability of error of 1% appears highly significantly more often than of patients with dysgnathias without sigmatism. With nearly 50% of persons with sigmatism in the same time showing a dysgnathia may be expected an abnormal mode of deglutition. Relationship between abnormal swallowing and sigmatisms is with 76.47% especially high at "protruding of the lower jaw", followed by "open bite" with 75%, then "extendet overjet" with 47.78%, whereas at "lack of room" this relationship may be observed at 35.42% of the cases.

Deglutition Disorders↗

[Muscle function therapy of the orofacial area].

Many disabilities, motorial disorders, tics, behaviour disturbances, habits, greater or smaller dysfunctions in the oral system and speech and voice damages concern the paediatrician in his daily practice. Very often these problems appear in combination or together with other pathologies, sometimes within difficult complex diseases. Different symptoms are mentioned helpful to the paediatrician. Often must be used diagnosis and therapy of different branches in a connected team-work. The demonstrated conception of the myofunctional therapy in the oro-facial system developed by the two authors, has to be seen in this respect. This conception has been tested on patients with dysgnathias, dyslalias and the two oro-facial dysfunctions deviate swallowing and habitual mouthbreathing. Characteristic features of this conception, its sources, its elements, its course, its methodical principles and its position in a paediatric complex therapy are demonstrated.

[Unusual rhythm disorders with a DDD pacemaker].

A tachycardia caused by an inadvertent change of the lead connections in a patient with a DDD pacemaker is reported. This was demonstrated by operating in different modes (i.e. AOO, VOO) by displaying the marker channel graphically and by X-ray examination revealing unchanged lead positions.

Rapid, easy and economical dot EIA for detection of antibodies to HIV-1 using recombinant env- and gag-proteins.

A rapid and simple screening test for antibodies to HIV-1 was designed on the principle of dot-EIA. Recombinant HIV-1 env and gag polypeptides are fixed on nitrocellulose sheets. Peroxidase conjugated protein A is used for detection of bound antibodies. After addition of hydrogen peroxide and 2-bromo-1-naphtol antigen-antibody complexes are visualized as discrete blue coloured spots. The test is completed within 15 min. Out of 111 sera positive by commercial EIA and Western blot analysis 110 were recognized by dot-EIA (sensitivity: 99.1%). False positive results compared with commercial EIA were found in 2 of 423 healthy blood donors (specificity: 99.5%).
