[Nickel sensitization in women and its relevance to occupation].

213 women and 26 men out of 7835 persons examined in the course of 9 years (1967--1975) had a positive reaction to nickle sulfate. The frequency of the sensitization to nickel increased during this time, from 0.9 to 5.01%. 121 of the sensitized women were less than 30 years old. The first manifestations of that contact eczema due to metal ions appeared on the earlobes, the fingers in the ring-region, the hands, the wrists and the neck. In most of the men but only in 20 women (1 photograph, 19 metallists), a professional cause could be revealed, and an occupational disease was recognized. In the other women, a non-professional cause was found. No hair-dresser had been sensitized to nickel, by an occupational contact. The increase of the allergy ot nickel from 1967 to 1975 was mainly due to wearing costume-jewelry since the localisation of the contact eczemas ofter corresponded to the trend of fashion. Before demanding the recognition as an occupational disease in case of positive tests, the relevance of the latter to the occupation of the subject should be elucidated.

[Fatal vitamin D intoxication].

A 43-year-old man with alopecia maligna was treated for 4 weeks with a total of 130 mg vitamin D3. Two weeks later, after intensive exposure to the sun, he developed a hypercalcaemic crisis and died 5 weeks later of acute cardiac failure. The hypercalcaemia proved treatment-resistant despite good diuresis. Causes other than vitamin D intoxication were excluded clinically and on histopathological investigations. It is suggested that vitamin D should be administered only on the strictest indications and with regular control of the patient.

[Dyshidrosis as a pacemaker for occupational dermatoses].

Out of 335 persons of less than 25 years, 236 had an intermittent dyshidrosis; half of them showed an allergic contact eczema of the hands. Microscopical and cultural investigations revealed a foot mycosis in 24 persons, and in 13 a candidiasis of the hands. Hence, dyshidrosis is obviously not of mycotic origin. 113 out of 150 sensitized persons of this group of age were dyshidrotics; 50% of them had not yet finished their apprenticeship. Obviously, dyshidrosis favours an early sensitization in professions in which allergens are frequently encountered.
