BACKGROUND: Nasal cytology in a easy-to apply method to differentiate rhinitis phenotypes from a physiopathogenic and diagnostic perspective. There are controversies about the relationship between clinical severity of rhinitis and inflammatory patterns expressed in the nasal cytology. OBJECTIVES: To study the characteristic of the eosinophil and neutrophil patterns in the nasal scraping for Allergic Rhinitis (AR) and Non Allergic Rhinitis (NAR) and its relationship with the clinical grades of rhinitis established by the Allergic Rhinitis and its Impact on Asthama Guideline (ARIA) Methods: In a observational, cross-sectional study we included patients aged 5 to 18 years presenting symptoms of either allergic (AR) or non- allergic rinitis (NAR) without asthma...

Antileukotriene drugs inhibit the formation or action of leukotrienes, which are potent lipid mediators generated from arachidonic acid in lung tissue and inflammatory cells. The leukotrienes were discovered in basic studies of arachidonic acid metabolism in leucocytes 20 years ago and were found to display a number of biological activities which may contribute to airway obstruction. Clinical studies with antileukotriene drugs have indeed demonstrated that leukotrienes are significant mediators of airway obstruction evoked by many common trigger factors in asthma...

Platelet-activating factor (PAF) is a newly discovered lipid mediator of inflammation. When inhaled by normal volunteers, it induces bronchoconstriction associated with facial flushing and with a transient fall in circulating neutrophils. Of greater interest is its ability to induce prolonged increases in bronchial responsiveness to methacholine. These observations support an important role for PAF in asthama; the availability of specific PAF antagonists will allow us to test this hypothesis.

The effect of atropine on sputum production has been studied in patients with asthama, chronic bronchitis, and bronchiectasis in some of whom there was bronchorrhoea. In three patients a reduction in sputum volume was observed after atropine but it would seem that the decrease was mainly due to the inhibitory effect on salivary secretion which facilitates spitting. The one patient treated with long-term oral atropine showed a marked reduction in sputum volume although chemical constituents and viscosity levels remained unchanged, suggesting that in this case atropine had an inhibitory effect on bronchial gland secretion...

Infantile asthama is an important pediatric problem and may cause substantial morbidity and mortality in this age group. The pathophysiology of allergic asthma involves a type I hypersensitivity reaction that is mediated by reaginic antibodies of the IgE class. Various factors predisposing to infantile asthma have been suggested but not confirmed. The differential diagnosis of infantile wheezing is of particular importance in this very young age group. An appreciation of the natural history and clinical characteristics of the disease, and of the important causative factors (foods, environmental inhalants, and respiratory infections), will aid the physician in the management of this problem...

The bronchial effect of intravenous atenolol (ICI 66.082) has been studied in a double-blind cross over trial in 10 patients with pronounced, labile bronchial asthama. A single i.v. dose of atenolol 3 mg. sufficient to cause a fall in heart rate and systolic blood pressure at rest, induced only a slight and clincially almost negligible impairment of ventilatory function. An ordinary therapeutic dose of salbutamol by inhalation far outweighed the bronchial effect of atenolol. The drug appears promising with regard to its cardio-selective properties...
