INTRODUCTION There is epidemiological, functional and pathologic evidence that relates upper and lower airways, clinically known as a single respiratory tract. Patients with allergic rhinitis without asthma may present subclinical abnormal spirometry parameters. OBJECTIVES To describe the results of the flow-volume curve in a group of patients with(More)
The link between upper and lower airways has been observed in the past, but only carefully investigated during the last years. Allergic rhinitis and asthma are often comorbid conditions. Its relationship is supported by epidemiological, anatomical and physiological, immunopathological, clinical and therapeutic studies, mostly related to allergic rhinitis.(More)
BACKGROUND Subclinical spirometric abnormalities may be detected in patients with rhinitis without asthma, proportional to the severity established by ARIA (Allergic Rhinitis and Its Impact on Asthma) guidelines. New criteria of rhinitis classification were recently validated according to the ARIA modified (m-ARIA), which allow the discrimination between(More)
Primary immunodeficiencies (PID) are low-prevalence diseases. There are warning signs that may raise clinical suspicion. The objectives of this study were to describe the clinical characteristics and warning signs of patients with PID and to compare the clinical differences between selective immunoglobulin A (IgA) deficiency and other PIDs. Eighty-nine(More)
The upper and lower airways behave as a physiological and pathophysiological unit. Subclinical lower airways abnormalities have been described in patients with rhinitis without asthma. These are expressed as bronchial hyperreactivity, abnormalities in lung function and bronchial inflammation, likely as a result of the same phenomenon with systemic(More)
Allergic diseases cause great impact on the health related quality of life in children and adolescents, resulting in increased school absenteeism and deficiencies in school performance. Although the bibliographic framework on allergic diseases is wide, in our country, there are no guidelines for proper management of the allergic child at school. It is(More)
In 1998, the Sociedad Argentina de Pediatría issued the recommendation of the treatment of anaphylactic shock. While this recommendation suggested the use of subcutaneous epinephrine, currently the intramuscular via is considered the most appropriate one. Pharmacological aspects determine this preference. For outpatient treatment, the correct use of(More)
Chronic cough is a symptom of various respiratory and non-respiratory conditions with negative impact on quality of life of children and their families. The pediatricians should focus their efforts in search for etiological diagnosis. A careful medical history and physical examination are the mainstays of diagnosis and guidance to further studies that may(More)
Asthma is one of the most common chronic diseases in children. While most children with asthma respond to low doses of inhaled corticosteroids and /or leukotriene receptor antagonists, some of them remain symptomatic regardless of any therapeutic effort, showing a high morbidity and even mortality. While most of the patients control symptoms adequately,(More)
