[Role of rhinomanometry in childhood mite allergy apropos of 76 cases]. Place for Passive Anterior Rhinomanometry (PAR) in mite allergic children. PAR is a simple method to investigate chronic or recurrent rhinopathies in children. Among 59 investigations with a Dermatophagoides pteronyssinus extract, we found 27 positive responses, 3 doubtful results and 32 negative explorations. Nasal sensitization is usually important: the liminal dose is less than 250 mcg in 17/28 cases. Most children have no bronchial sensitivity. None of 14 children with negative cutaneous and RAST tests have nasal sensitivity. When cutaneous and RAST tests are both positive, 12/16 positive PAR are found. We note a nasal sensitivity in 3/5 cases with only cutaneous test positive and 12/26 cases with only RAST tests positive. For other mites a nasal sensitivity is found in 8 out of 14 explorations (Tyrophagus and Glyciphagus especially). Among all patients when cutaneous tests, RAST tests and history are doubtful for the real part played by mites in the child rhinopathy, nasal exploration allows more explicit diagnostic and therapy.
