The brain is especially sensitive to heat stress. To limit the increase of intracranial heat in case of hyperthermia or fever, a system of selective cooling is put on. It includes two heat-exchangers. ⋯ They are connected by a vascular network. In these conditions, the arterial blood temperature, of which cerebral temperature depends upon, is reduced by the cooled venous blood which comes from subcutaneous tissues through the skull wall. On feverish children, increasing such a selective cooling by face fanning can limit cerebral thermal stress.

Allergic bronchopulmonary aspergillosis (ABPA) associates the development of aspergillus in bronchus and a predominant immediate hypersensitivity for aspergillus antigens. It complicates an old and severe allergic asthma or cystic fibrosis. Its prevalence is not well known. ⋯ Systemic corticotherapy is the usual treatment of exacerbation. The association with inhaled corticotherapy could reduce the duration of systemic treatment. The use of Itraconazole is logical, mainly in cystic fibrosis.
