Early-onset atopic asthma is the most common phenotype of asthma in childhood, called intrinsic asthma in the earlier intrinsic/extrinsic classification. Patients with early-onset atopic asthma frequently have a family history of atopy, and are sensitised to common allergens. This phenotype usually responds well to inhaled corticosteroids, and ...
If the person with a severe asthma exacerbation is on a mechanical ventilator, certain sedating medications such as ketamine or propofol, have bronchodilating properties. According to a new randomized control trial ketamine and aminophylline are also effective in children with acute asthma who responds poorly to standard therapy. [9]
Restrictive lung disease is characterized by reduced lung volumes, and therefore reduced lung compliance, either due to an intrinsic reason, for example a change in the lung parenchyma, or due to an extrinsic reason, for example diseases of the chest wall, pleura, or respiratory muscles. [3]
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis (EAA) is a syndrome caused by the repetitive inhalation of antigens from the environment in susceptible or sensitized people. [ 1 ] [ 2 ] Common antigens include molds, bacteria, bird droppings, bird feathers, agricultural dusts, bioaerosols and chemicals from paints or plastics ...
A Swedish research study titled "Atopy In Children Of Families With An Anthroposophic Lifestyle" comparing the rate of bronchial asthma, allergies, dermatitis, and other atopic diseases among Steiner school pupils and pupils in public schools originally appeared in the May 1, 1999, edition of the British medical journal The Lancet. The findings ...
Asthma is divided into two subgroups: atopic (extrinsic) and non-atopic (intrinsic). The atopic subgroup is closely associated with family history of the disease, whereas the non-atopic subgroup has its onset in adulthood and it is not caused by inheritance. It is known that non-atopic asthma has a more severe clinical course than atopic asthma.
