Bronchial asthma is one of the most frequent pulmonary diseases of the childhood. Albeit its diagnosis is mostly based on history and few simply laboratory test, still asthma seems to be underdiagnosed virtually in every population. To make matters worse, asthma treatment is often far from perfection. Asthma control in children is often not assessed. This situation happens despite of country or region for many reasons. Asthma is often treated by GP and several specialists (pediatricians, pulmonary physicians and allergists). Some of them have relatively small experience in treating children, though they have many successes in adults. Current asthma treatment guidelines in most cases are just small parts of an adult consensus. Sometimes, even children guidelines are derived from CRTs done in adults’ asthmatics. To help all physicians to treat childhood asthma, the PRACTALL consensus group have been formed few years ago. Recently, “Allergy” publish PRACTALL (an acronym taken from PRACTical ALLergy), an EBM guidelines focused on child asthma diagnosis and therapy. The document was prepared by allergists and pediatricians from Europe and the USA. This is the first worldwide children asthma consensus. Some aspects of new guidelines are really a breakthrough in asthma diagnosis and therapy in children, especially in babies 0-4 years old. This review is an approach to summarize major aspects of PRACTALL.
