[Nickel, chromium and cobalt release from a metal prosthesis in metal-sensitive patients].

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.

Contact dermatitis from nickel: an investigation of its sources.

Patch tests with the GEIDC standard series of allergens, and with 8 washers made of copper, nickel, nickel-palladium, palladium, brass, bronze, gold and iron, were carried out in 964 consecutive patients who complained of intolerance to metals and in 200 controls who did not. All subjects were also questioned as to personal and family history of atopy, occupational contact and intolerance to gold. The results provide support for the substitution of nickel in imitation jewelry with metals such as palladium or bronze.

[The concept of cryptic cutaneous atopy in contact reactions. Considerations on the clinical control over the subgroup of patients with frustrated cutaneous atopy].

Contact dermatitis, allergic or irritative, is not distributed by chance among the general population, but appears in a determined group of patients. The clinical and anamnestic picture of this group of patients (and that of their close blood relatives) is described. Clinical facts lead us to consider that group of patients as a subgroup of cutaneous atopy. The medical-legal importance which the acceptance of this type of patient could have on occupational contact dermatitis is pointed out. In contact dermatitis the factors of the person suffering the contact rather than those of the contact agents seem to be of decisive power in the response, although at the present moment, the possibility of carrying out analytical studies on the allergens and irritants is easier than on the patients who react to them.

[Dry hands (irritative contact dermatitis) in housewives which is not alleviated on cessation of domestic work: clinical varieties].

There are three types of hand dermatitis in housewives. The most usual are cured when housework is stopped. Another type is that of housewife contact dermatitis which appears on pre-existing endogenous lesions such as dyshidrosis or nummular eczema. The third form is housewife hand contact dermatitis which appears, or coexists with, localized endogenous lesions of the hands. The last two forms are not cured when housework is stopped. In some cases the three forms may coexist or appear one after another. It is not usual for a person suffering from typical flexural atopic dermatitis to present with one of the described three forms of hand dermatitis. Nevertheless, without having some relationship to atopic diathesis no woman could suffer from any of these three forms of dermatitis. In spite of the lack of analytical data, everyday clinical facts (one example being these different forms of housewife hand dermatitis) suggest the need to accept a subgroup of cutaneous atopic diathesis.

Cobalt content of household cleaning products.

In our Department, the incidence of sensitization to cobalt has more than doubled in the last 5 years. 28% of cobalt-sensitive patients showed no other sensitivity. Of isolated cobalt sensitive patients, 68% were housewives. We determined by atomic absorption spectrophotometry with a graphite camera, the cobalt and nickel content of the 30 most popular Spanish domestic detergents and cleaners sold in 1985. 78.6% of them contain considerable amounts of cobalt.

[Contact dermatitis caused by nickel].

This paper attempts to explain the initial onset in which the population are sensitized to nickel at an early age, above all in females. A study has been made on 200 controls who tolerated metals and on 964 patents who did not tolerate them. The study comprised of patch tests with 8 distinct washers, made of a variety of metals and alloys all containing nickel, and with nickel sulphate to 1% in petrolatum and cobalt salts to 1% in petrolatum. The results, professional and atopic relationship and other considerations are commented.
