In rare cases, children can develop anaphylactic allergies to previously tolerated foods after receiving blood products via transfusion, report the authors of a case study published in CMAJ (Canadian Medical Association Journal).
A new blood test promises to predict which people will have severe allergic reactions to foods according to a new study led by Mount Sinai researchers and published online in the The Annals of Allergy, Asthma & Immunology.
Peanut butter and jelly sandwiches are a dietary staple for many children. But for others, peanut products can be life-threatening and are strictly taboo. A new study released at a meeting of the American Academy and Association of Allergies and Immunology (AAAAI) and published in the New England Journal of Medicine suggests that peanut allergies can be prevented through early exposure.
A new study carried out by LMU researchers has found no evidence for the notion that an overemphasis on personal and household hygiene stimulates the development of childhood allergies and asthma. The finding is based on data obtained from 400 families, which was compiled and analyzed by the research group led by Professor Erika von Mutius, Head of the Outpatient Department of Asthma Allergies at Dr. von Hauner Children’s Hospital, Munich. The results appear in the American Journal of Respiratory and Critical Care Medicine.
With winter loosening its icy grip on most of the United States, it’s time to think about spring allergies, a doctor says. Allergies to spring pollens cause sneezing, stuffy and runny nose, and watery eyes. Other symptoms include itchy nose, mouth, throat, eyes and ears, said Dr. Luz Fonacier, head of allergy and training at Winthrop University Hospital in Mineola, N.Y.
Triclosan – an antibacterial chemical found in toothpaste and other products – can contribute to an increased risk of allergy development in children. This comes from the Norwegian Environment and Childhood Asthma Study, in which the Norwegian Institute of Public Health is involved. Similar results are reported in the USA.
Some patients with asthma have frequent exacerbations and persistent airflow obstruction despite treatment with inhaled glucocorticoids and long-acting beta-agonists (LABAs).
In patients with poorly controlled asthma despite the use of inhaled glucocorticoids and LABAs, the addition of tiotropium significantly increased the time to the first severe exacerbation and provided modest sustained bronchodilation.
Anticholinergic agents have been available for the treatment of airways obstruction for many decades. For patients with chronic obstructive pulmonary disease (COPD), many practitioners believe that these drugs have become the bronchodilator of choice. For patients with asthma, anticholinergic agents are less popular, probably because of their slower onset of action as a reliever medication and their generally inferior effect on lung function and symptoms, as compared with inhaled beta-agonists.
Acute bacterial sinusitis is diagnosed in children with persistent rhinorrhea and cough, severe symptoms, or worsening of symptoms after initial improvement. Antibiotic therapy is recommended, and amoxicillin–clavulanate is generally the first-line treatment.
The use of inhaled glucocorticoids for persistent asthma causes a temporary reduction in growth velocity in prepubertal children. The resulting decrease in attained height 1 to 4 years after the initiation of inhaled glucocorticoids is thought not to decrease attained adult height.
