There are various references to sensitization to beryllium in the literature. Since introducing a patch testing series for patients with suspected sensitization to metals, we have found 3 cases of sensitization to beryllium. Of these 3 cases, we regard the first 2 as having relevant sensitization. Beryllium chloride (1% pet.) was positive in 3 patients and negative in 150 controls.

Owing, on the one hand, to the constant increase in the %s of nickel sensitization in the majority of allergy departments of dermatology and, on the other, to the fact that sensitization to nickel is almost always through contact with jewellery and imitation jewellery, an update was carried out on the metal alloys principally used in the manufacture of such jewellery (earrings, bracelets, necklaces, rings, watch straps, etc.) The conclusions of this review demonstrate that nickel is irreplaceable in the majority of the alloys, because of its excellent technical properties and low price and, as a result, the % of sensitizations to this allergen will not only maintain their present high level but will probably increase in the future.

Clenbuterol, a beta antagonist, and ranitidine, a histamine-receptor antagonist, were associated with contact dermatitis in a chemist. The allergen in the former was an intermediate in the synthesis called beta. In the latter, intermediates and the finished base and hydrochloride were responsible.

Six rejected stainless steel hip prostheses that had been removed from 15 metal sensitive patient were immersed in different solutions in various containers and maintained at 37 degrees C in complete darkness. Two months later by means of atomic absorption spectrophotometric studies we were able to determine the amount of nickel, chrome and cobalt released in a saline solution. When the chromium oxide passivation coat of the metal prostheses is damaged by orthopaedic surgical implantation procedures the prostheses may rust, releasing metallic ions.
