Quantitative relations between dietary fat and cholesterol and plasma lipid concentrations have been the subject of much study and some controversy during the past 40 y. Previous meta-analyses have focused on the most tightly controlled, highest-quality experiments. To test whether the findings of these investigations are generalizable to broader(More)
Intercellular adhesion molecules (ICAMs), in particular ICAM-1, appear to play a crucial role in the recruitment and migration of inflammatory cells to the site of an allergic reaction. Glucocorticoids and allergen-specific immunotherapy have been shown to exert effects on selected components of this system, both in vitro and in vivo, but further research(More)
BACKGROUND Asthma exacerbation is an episode of (sub)acute worsening of asthmatic symptoms. Exacerbation may depend on environmental factors. OBJECTIVE The present study investigated emergency calls for asthma exacerbation in children, analysing: i) their trend over the course of time; and ii) their possible relationship with environmental factors,(More)
BACKGROUND Allergic rhinitis is associated with Th2-dependent inflammation. Nasal obstruction is the most typical symptom in children with mite allergy. OBJECTIVES The aim of this study was to evaluate the possible relationships among nasal symptoms, allergic inflammation, including inflammatory cells and cytokine pattern, and nasal airflow in children(More)
To elucidate whether deep inhalation (DI) modulates changes in airway caliber in childhood, we measured the effect of DI on respiratory impedance before and after inhaled methacholine or salbutamol in 4- to 7-yr-old children (n = 15) suffering from recurrent wheezing. In all children, the real part of impedance between 12 and 16 Hz (Re[Z](12-16)) increased(More)
BACKGROUND Nasal obstruction is the main symptom in patients with persistent allergic rhinitis. Some antihistamines have been demonstrated to be capable of improving this symptom. The aim of this pilot study was to evaluate nasal symptoms, nasal airflow, and decongestent activity in patients with persistent allergic rhinitis, before and after treatment with(More)
BACKGROUND Allergic rhinitis is traditionally subdivided into seasonal (SAR) and perennial (PAR), although the new definitions of persistent and intermittent were recently proposed. We assessed the validity of the traditional classification in a large group of subjects suffering from allergic rhinitis alone. METHODS Young males referred to a Navy Military(More)
BACKGROUND Previous surveys on Italian conscripts showed a low prevalence of allergic rhinitis. This study investigated the prevalence and the treatment of allergic rhinitis in the "conscript model" during a four-year period (1999-2002). METHODS 28,327 18-year old males were screened and referred to La Spezia Military Navy Hospital for call-up visit.(More)
BACKGROUND Nasal obstruction is a typical symptom of allergic rhinitis. Allergic rhinitis is characterized by a Th2-dependent inflammation. The aim of this study was to evaluate the possible relationships between allergic inflammation, including inflammatory cells and cytokine pattern, and nasal airflow in patients with nasal obstruction due to seasonal(More)
FEV1 is considered an important parameter for asthma diagnosis and follow-up. However, it has been proposed that FEF25-75 could be more sensitive than FEV1 to detect slight airways obstruction. Bronchial reversibility defined by positive response to bronchodilation test. The aim of the present study was to define whether an impaired FEF25-75 value (less(More)
