Age at onset presents possibility to improve asthma management By Kirsty Oswald.

Patients aged 50 years or older at starting point had the cheapest incidence of asthma attacks in the past 12 months in accordance with those whose onset occurred at age groups 5 to 9 years. Writing in Respiratory Medicine, Mirabelli et al suggest that as children identified as having asthma at a very young age probably had their condition primarily handled by their parents, they might not need developed the same self-management skills of children diagnosed at a later age.

Age at onset presents possibility to improve asthma management By Kirsty Oswald, medwireNews Reporter Researchers have shown that age at medical diagnosis of asthma may impact future outcomes and level of symptom control.Molecular Analyses Genomic DNA was isolated from peripheral-blood lymphocytes or spermatozoa by using a commercial extraction kit, based on the manufacturer’s protocol.12 In order to define the degree of deletion, we used several sequence-tagged sites and gene-specific primers to localize the breakpoints to an interval spanning less than 1 kb . All PCR assays were performed on DNA produced from a woman as a poor control and DNA from a fertile male as a positive control. The total results were considered negative only after three consecutive failures of amplification; occasionally the experiments were repeated on DNA extracted from the second blood samples obtained from the patient and his brother and father.
