[Is it necessary to test children having summer respiratory problems with cereal pollens?]. / Faut-il tester aux pollens de céréales les enfants présentant des troubles repiratoires estivaux?

We tested 100 children with clinical signs that occurred in spring or summer. Prick tests were made with extracts of wild grass pollens (Dactylis, Phleum, Lolium) and with separate cereal pollens (Wheat, oats, Sweet-corn Barley and Rye). In 20 children whose test was negative for wild grass pollen, we saw no sensitization to cereals. In 80 children with grass pollenosis, Barley and Rye are the cereals that gave the most positive prick tests, whilst sweet corn is the cereal with most negative tests.

[Long-term tolerance of specific hyposensitization with the aid of calcium phosphate-adsorbed mite extracts]. / Tolérance à long terme de l'hyposensibilisation spécifique à l'aide d'extraits d'acariens adsorbés sur phosphate de calcium. A propos de 90 observations traitées de façon semi-rapide.

90 children receive a specific hyposensitization with calcium phosphate adjuvant purified Dermatophagoides pteronyssinus allergens. We note 44% very good results, 37% good results and 19% failures. We propose to begin with 1/1,000,000 concentration every other day until 1/10,000 concentration is obtained under antihistamine protection. Tolerance is satisfactory: moderate respiratory reaction are pointed out for 22 patients. No anaphylactic shock is encountered. For 80 children with more than three years recall, we totalled 3,700 injections for 340 watching years. Only eight patients are sight lost. 1/10,000 concentration is obtained in 72/80 followed up children.
