[Provisional restorations in fixed prosthetics. Combination of photopolymerizing resin and composites].

This study shows the interest of using a light cured resin for temporary restorations. The rubber like stade enables easy removable of undercuts and excess material can be trimmed easily before light irradiation. Physico-chemical properties of light cured resin are compared with those of four chemical-polymerizing resins. Exothermic reaction, transverse strengths, modulus of elasticity, and differential scanning calorimetry show the same values as the best autopolymerizing resins. The author presents an original technic, using the light cured resin with light cured composites to achieve aesthetic and strong temporary restorations.

[Prolactinemia in primary hypothyroïdism : basal and dynamic studies--signification of galactorrhea associated with myxedema (author's transl)].

PRL and TSH were measured by radioimmuno-assay in 14 persons wth myxoedema aged 16 to 65 years. Three of them had galactorrhea. In 13 patients the circadian rhythm of PRL was studied, and in 8 patients PRL was measured after TRH administration. All these patients have a high value of serum TSH, with a mean value +/- SEM of 29,4 (24,3 - 35,6) mU/ml. Values of serum PRL were comprised in normal ranges with a mean value +/- SEM of 126(196 - 238) mU/ml. The circadian rhythm of PRL is not altered, since mean values of serum PRL are more elevated at 4 am than 8 am with highly statistical significance. After THR administration the PRL response is normal or exaggerated.
