[Findings of computed tomography in multiple sclerosis-correlation of clinical findings with computed tomography in clinically definite 14 patients of multiple sclerosis (author's transl)].

Recent introduction of Computed Tomography (CT) in clinical neurology made it possible to visualize the brain lesion without any invasive procedures. In multiple sclerosis (MS), the demyelinating foci were reported to be observed as low density areas on CT, but occasionally contrast enhanced high density areas were reported also. So far as we know, only a few reports which analysed interrelationship between clinical signs and CT findings were published. In this report we tried to examine the correlation of clinical findings with CT in MS. All scans were performed using an EMI head scanner (EMI 1000) with a 160 X 160 matrix. Contrast material was administered as an intravenous bolus of 60% meglumine iothalamate. In clinically definite 14 MS patients, CT showed localized, circumscribed low density areas in 4 patients, periventricular low density in 1 patient, widening of cortical sulci with ventricular dilatation in 11 patients and no abnormalities in 3 patients. The widening of cortical sulci with ventricular dilatation were noted to be particularly common findings. The periventricular low density was not so frequently seen as we expected. Localized, circumscribed low density areas on CT were well correlated with the neurological findings in 2 patients. In these cases the abnormalities on CT persisted in spite of neurological improvement. As a conclusion, we think CT might be useful as a diagnostic evaluation of MS.

Short rib-polydactyly syndrome, Majewski type, in two male siblings.

Two male siblings with a short rib-polydactyly syndrome, Majewski type (Majewski syndrome), are reported. To our knowledge, the present report is the first one of siblings each confirmed to be affected by Majewski syndrome, and it may therefore contribute to establishing the mode of inheritance.

Adhesion between copper-plated acrylic tray resin and a polysulfide rubber impression material.

The method of copper plating on acrylic resin was developed, and the bond strength to polysulfide rubber was measured in comparison with that of the adhesive coating. The bond strength with copper plating was greater than with adhesive coating. The specimens with adhesive coating failed due to a rupture occurring at the elastomer-adhesive interface, while those with copper plating had cohesive-adhesive failure. The method of copper plating on acrylic resin improved the adhesion between the polysulfide rubber and the custom-built acrylic resin tray.

Casting a gold alloy to embedded precision attachment metals.

The technique for casting a gold alloy to embedded attachment metals has been described. The joints of gold alloy cast to commercially available attachment metals were examined with a metallurgic and a scanning electron microscope. The investigation indicated that an uninterrupted gapless joint is possible, and that some diffusion occular along the interfaces with some attachment metals. In view of these findings, it is concluded that this technique can be recommended as a dental laboratory procedure.
