Cyanide exposure in fires.
The toxic hazard from cyanide produced in fires was assessed in casualties and in firemen exposed to the fire atmosphere. The levels of cyanide and its principal metabolite, thiocyanate, were measured in blood samples from fireman, non-fetal and fatal casualties, and from controls. Although firemen did not differ significantly from controls, casualities showed significant elevation of blood-cyanide, and in a small proportion of fatalities blood-cyanide reached toxic levels.

Pulmonary thromboembolism after travel.
Pulmonary thromboembolism developed in eight patients shortly after travel. Preexisting vein disease was present in this group. Possible prophylactic measures are suggested.
Comparision of a glutaraldehyde-modified pollen--tyrosine adsorbate with an alum-precipitated pollen vaccine in the treatment of hay fever.
Nineteen patients with hay fever symptoms received nine weekly injections of pyridine-extracted alum-precipitated grass pollen vaccine (Alavac P). The results were compared with agroup of twenty patients who received a three injection series of a glutaraldehyde-modified pollen-tyrosine vaccine (Pollinex). In both groups 65% had a subjective improvement in their symptoms and no significant difference in symptom scores was obtained throughout the pollen season. In the Pollinex group a lower incidence of systemic side effects was recorded.

Bronchial provocation studies in farmers allergic to storage mites.
In an investigation of the relationship between storage mites and symptoms of allergic respiratory disease in farmers exposed to hay and grain dust, the clinical responses suggested an immediate type-I hypersensitivity. This study confirmed that farmers are exposed to large numbers of mites, particularly while feeding cattle. Storage mites may be an important cause of asthma in the farming community and should also be considered in the differential diagnosis of farmers lung.
