Fluticasone furoate nasal spray in the treatment of allergic rhinitis
Allergic rhinitis (AR) is a prevalent disease with great morbidity and significant societal and economic burden. Intranasal corticosteroids are recommended as first-line therapy for patients with moderate-to-severe disease, especially when nasal congestion is a major component of symptoms. To compare the efficacy and safety profile of different available intranasal corticosteroids for the treatment of AR, it is important to understand their different structures and pharmacokinetic and pharmacodynamic properties. Knowledge of these drugs has increased tremendously over the last decade. Studies have elucidated mechanisms of action, pharmacologic properties, and the clinical impact of these drugs in allergic respiratory diseases. Although the existing intranasal corticosteroids are already highly efficient, the introduction of further improved formulations with a better efficacy/safety profile is always desired. Fluticasone furoate nasal spray is a new topical corticosteroid, with enhanced-affinity and a unique side-actuated delivery device. As it has high topical potency and low potential for systemic effects, it is a good candidate for rhinitis treatment
Difficult‐to‐control asthma management through the use of a specific protocol
The present study is a critical review of difficult‐to‐control asthma, highlighting the characteristics and severity of the disease. It also presents a protocol for the management of patients with this asthma phenotype. The protocol, which was based on relevant studies in the literature, is described and analyzed

The hammock: a reservoir of allergens
INTRODUCTION: Asthma affects approximately 10% of the world's population. Sensitization to allergens is an important risk factor, and exposure to allergens is associated with disease severity. METHODS: We performed skin tests to evaluate allergen sensitization to mites, cockroaches, cats, dogs, and molds in 73 asthmatic patients. Enzyme Linked Immunosorbent Assay was used to assay the mite and cockroach allergens found in dust from the bedding, hammocks, bedroom floors, living rooms, and kitchens of 29 patients and 14 controls. RESULTS: Fifty patients (68.5%) had positive skin test responses. There were positive responses to D. pteronyssinus (52.0%), B. tropicalis (53.4%), T. putrescentiae (15.0%), E. maynei (12.3%), L. destructor (8.2%), B. germanica (20.5%), P. americana (21.9%), Felis catus (10.9%), C. herbarium (2.7%), A. alternata (4.1%), and P. notatun (1.3%). The exposure to mite and cockroach allergens was similar in the patients and the controls. The Dermatophagoides pteronyssinus Group 1 levels were highest in the beds and hammocks. The Blattella germanica Group 1 levels were highest in the kitchens, living rooms and hammocks. DISCUSSION: The positive skin tests to mites, cockroaches and cats were consistent with previous studies. D pteronyssinus was the most prevalent home dust mite, and hammocks were a source of allergens. To improve asthma prophylaxis, it is important to determine its association with mite allergen exposure in hammocks
