Prednisolone versus antihistamine for allergic rhinitis: No significant difference found in randomized trial.

Background: Seasonal allergic rhinitis (AR) impacts public health by affecting work productivity and quality of life. The Swedish tree pollen season starts in February with alder and hazel pollination, followed by birch and ends with oak in May. Systemic corticosteroids are often prescribed when topical treatments fail, despite limited evidence supporting their efficacy.

Limited beneficial effects of systemic steroids when added to standard of care treatment of seasonal allergic rhinitis.

Intramuscular injections with methylprednisolone treating allergic rhinitis (AR) have a long history. Modern guidelines are designed to dissuade this treatment, but it´s frequently used, especially in primary care. This despite of concern for side effects and lack of modern placebo-controlled studies.

HealthSWEDE: costs with sublingual immunotherapy-a Swedish questionnaire study.

Background: The aim of this cross-sectional survey was to compare the health-economic consequences for allergic rhinitis (AR) patients treated with sublingual Immunotherapy (SLIT) in terms of direct and indirect costs with a reference population of patients receiving standard of care pharmacological therapy.

Methods: Primary objective was to analyse the health-economic consequences of SLIT for grass pollen allergy in Sweden vs reference group waiting for subcutaneous immunotherapy (SCIT). A questionnaire was mailed to two groups of AR patients.

Development and external validation of a risk-prediction model to predict 5-year overall survival in advanced larynx cancer.

Objectives/hypothesis: TNM-classification inadequately estimates patient-specific overall survival (OS). We aimed to improve this by developing a risk-prediction model for patients with advanced larynx cancer.

Study Design: Cohort study.

Kinin-stimulated B1 receptor signaling depends on receptor endocytosis whereas B2 receptor signaling does not.

Kinins are potent pro-inflammatory peptides that act through two G protein-coupled receptor subtypes, B1 (B1R) and B2 (B2R). Kinin-stimulated B2R signaling is often transient, whereas B1R signaling is sustained. This was confirmed by monitoring agonist-stimulated intracellular Ca(2+) mobilization in A10 smooth muscle cells expressing human wild-type B2R and B1R.

Kinins promote B2 receptor endocytosis and delay constitutive B1 receptor endocytosis.

Upon sustained insult, kinins are released and many kinin responses, such as inflammatory pain, adapt from a B2 receptor (B2R) type in the acute phase to a B1 receptor (B1R) type in the chronic phase. In this study, we show that kinins modulate receptor endocytosis to rapidly decrease B2R and increase B1R on the cell surface. B2Rs, which require agonist for activity, are stable plasma membrane components without agonist but recruit beta-arrestin 2, internalize in a clathrin-dependent manner, and recycle rapidly upon agonist treatment.
