Results and discussion

Results of examinations:
On examination, unable to talk in full sentences;
Respiratory rate was 24/min with an oxygen saturation of 94% in room air;
Chest examination was normal;
Pulse rate was 100/min and he was feverish at 39°C;
Blood gas analysis demonstrated acute type I respiratory failure with an arterial oxygen partial pressure of 8.8 kPa;
There was a neutrophil leucocytosis but no other abnormality of baseline pathology;

Applicant's summary and conclusion

Conclusions:
According to the authors, Metal fume fever (MFF) is an acutely noxious inhalation syndrome secondary to metal oxide fumes. Despite preventative strategies sporadic cases are likely to continue to present to emergency departments. MFF is classically associated with zinc oxide fume exposure from welding galvanized steel or brass. It is also seen in association with high temperature zinc coating processes and metal pouring in brass foundries. Magnesium and copper oxide fumes are more rarely the causative agents.
Executive summary:
A case of Metal fume fever (MFF) is described and a short review of the literature on the background, pathogenesis, and clinical presentation of this syndrome is provided. According to the authors MFF is mainly associated with exposure to zinc oxide fume, rarely with magnesium and copper oxide fume. Iron oxide fume is not mentioned.
