BACKGROUND The relationship between gastroesophageal reflux (GER) and asthma has been widely studied in the last years. GER may interfere with airway reactivity and aggravate or even induce asthma. OBJECTIVE To assess the prevalence of bronchial hyperresponsiveness (BHR) in patients with GER disease with a view to judging the potential influence of GER on(More)
BACKGROUND Nasal polyposis (NP) often coexists with asthma, rhinitis and sinusitis. Polyp histology typically shows chronic, eosinophilic inflammation. The inflammatory cell infiltrate generally includes eosinophils, lymphocytes, plasma cells and mast cells. OBJECTIVE To gain insight into the natural history of NP, we analysed mediator levels and(More)
It has been shown that leukocyte adhesion mechanisms play an important role in the development of allergic inflammation in bronchial asthma. We measured the circulating levels of E-selectin (formerly called sElam-1) and intercellular adhesion molecule-1 (ICAM-1) by ELISA in asthmatic subjects. We selected 10 asthmatic subjects to study during an asthma(More)
DESIGN OF STUDY Two groups of patients undergoing long-term dialysis were studied in order to evaluate the importance of ethylene oxide (EtO) in causing allergic reactions during dialysis. The first group of 50 subjects had never shown any hypersensitivity reactions related to dialysis, whereas the second group of 20 subjects had previously complained of(More)
We present a case of urticaria in a tattooed patient due to hypersensitivity to the cobalt chloride contained in the blue ink used for tattoo. The patch test with the series of International Contact Dermatitis Research Group was positive only for chloride cobalt. Cobalt is believed to be responsible for contact urticaria through a non-immunological(More)
Although copper sulfate can cause systemic contact dermatitis, few such cases have been recorded among copper-releasing IUD users. Reported in this paper is a case of endometritis and urticaria-angioedema syndrome in a 32-year-old user of a copper IUD. Widespread urticaria, as well as angioedema of the eyelids and the labia majora and minora, persisted(More)
BACKGROUND Most respiratory diseases involve the heart and can lead to acute or chronic pulmonary heart in the most serious cases. The common pathogenetic element is pulmonary arterial hypertension which es secondary to the resistance of the pulmonary circulation together with hypertrophy and/or dilatation of the right ventricle, caused mainly by chronic(More)
In this study, the authors evaluate the inhalant substances of the house, emphasizing the importance of Dermatophagoides pteronyssinus to cause perennial allergic rhinitis. They report the incidence of this and other allergens in 140 patients with perennial allergic rhinitis and the pertinent precautionary measures.
