ABSTRACT

A 28-year-old man developed asthma 10 years after working in a metal-plating factory. Recordings of peak expiratory flow rates showed increased variations after exposure at work. Allergy prick skin tests elicited an immediate reaction with nickel sulfate at a concentration of 1 and 10 mg/ml, and with zinc sulfate at a concentration of 10 mg/ml. Inhalation challenges with nickel sulfate and zinc sulfate produced bronchial obstructions. Thus, we concluded that this was a case of asthma caused by nickel sulfate and zinc sulfate.

f1-kjim-1-2-259-20: Monitoring of PEFR after occupational exposure. Initial PEFR was 505 L/min. The percentage fall of PEFR was 25% at midnight after the second working day.

Mentions: Figure 1 shows the variations of PEFR after exposure to the usual working conditions. Before re-exposure he had postponed returning to work for 3 weeks since the latest attack of asthma had developed. Initial PEFR on the Wright peak flow meter was 505 L/min. The percentage fall of PEFR was 13% one hour after finishing work on the first day and 25% at midnight after the second working day.
