[Respiratory sensitization to molds in children: myth or reality?].

The authors have made a systematic study by PRICK-test and RAST, sometimes followed by a rhino-manometric provocation, of the frequency of sensitization to the two moulds Alternaria and Cladosporium in 200 "all comers" children in a paediatric consultation. The frequency was low, only 10% for those consulting in the groups of asthma, rhinitis, pollinosis, repeated respiratory infections and syndromes of obstructed expiration taken together, and 13% for allergic asthma only. This sensitivity is rarely isolated, but is most often accompanied, or complicated by, other pneumoallergens, such as dust, mites, pollens and sometimes cockroaches. It imposes certain particular clinical traits on asthma (summer asthma or recurring asthma) and in others appears to be strongly influenced by the habitat. The skin tests seem to be very weak and RAST insufficient to be sure of real sensitization. Diagnosis, always difficult, is probably best done by a provocation test (preferably rhino-manometry) and this jumps over the bundle of clinical and biological arguments, as well as being, at least in our country, the most useful mimic of atmospheric moulds. The authors insist on the importance of the interrogation which should be concerned with the chronological and environmental circumstances and all respiratory infections that are suspected of having an allergic factor.

[A simple test for the detection of respiratory allergy to current pneumallergens].

Phadiatop is a new in vitro test used for screening patients with allergic respiratory diseases. This test, based on the RAST procedure, is performed with a paper disc to which a balanced mixture of relevant inhalant allergens has been coupled. One hundred and one adults ranging in age from 18 years to 73 years and 38 children (4 months to 15 years) were studied. We found a good correlation between this new test and total IgE (adults: 74.3 p. 100, children: 68.4 p. 100), specific IgE (adults: 91.1 p. 100, children: 100 p. 100) and skin test (adults: 79.2 p. 100, children: 97.1 p. 100). There was a high correlation between clinical atopy assessment and the result of Phadiatop, its efficiency was 83 p. 100 in adults and 97 p. 100 in children.

[History of hunting ... to cockroaches].

A 12.5 year old Cambodian boy had a chronic rhinitis with conjunctivitis since 5 years. Skin tests and RAST were positive only for cockroach allergen. The patient used to catch cockroaches to feed his fish. After disinfection of the apartment and desensitization therapy, the boy's symptoms disappeared within 7 months. The author recommends that skin tests and RAST for cockroaches may be used in the investigation of chronic rhinitis with conjunctivitis or asthma.

[Hymenoptera stings: the atopic person in danger. Allergy to Hymenoptera venoms].

The author reviews the clinical and therapeutic aspects of hymenoptera sting diseases in children. Lethal anaphylactic reactions are very rare. Progresses in prophylactic treatments of patients with a history of anaphylactic reaction have been made through venom immunotherapy, but a careful analysis of the clinical data must be done before starting such a treatment.
