Objective: The aim was to evaluate the impact of Cupressus sempervirens (Cs) and Juniperus communis (Jc) sensitisations in "Maremma" in southern Tuscany. Methods: 811 consecutive outpatients (357 F - 57.86%; age: 36.9 ± 16.6) with suspected allergic respiratory symptoms underwent skin prick tests (SPT) for common allergens and for Cs and Jc. Result....
Comparative long term effects of nebivolol and carvedilol in hypertensive heart failure patients
Background: Beta-blockers improve left ventricular (LV) systolic function and prognosis in patients with chronic heart failure (CHF), but their different pleiotropic properties may influence their cardiovascular effects. This open-label study compared the effects of long-term treatment with nebivolol versus carvedilol on LV ejection fraction (LVEF)....
Sensitization to horse allergens in Italy: a multicentre study in urban atopic subjects without occupational exposure
Background: Horses play a significant role in people's leisure time in Italy and other countries, but few data are available on IgE-mediated sensitization to horse allergens in patients without occupational exposure. We assessed, in a multicentric survey, the prevalence of horse sensitization in atopic subjects and its clinical characteristic....
A regular or an intermittent treatment for asthma: the long-term effect
Objectives: Many asthmatics take therapy intermittently because of their scarce compliance. It is not known if this is effective in controlling and slowing down the lung function decline in asthma. Our aim was to compare the effect of a regular treatment and an intermittent one on some clinical aspects and on the forced expiratory volume 1 (FEV1) d....
Mesalazine-induced multi-organ hypersensitivity
Mesalazine therapy for ulcerative colitis has been reported to be effective and safe. Rare cases of mesalazine-induced renal, pancreatic, myo-pericardial, pleuro-pulmonary and haematological toxicity have been described separately. We report a case characterized by the simultaneous presence of fever, pericarditis, peripheral eosinophilia, eosinophi....
Influenza A H1N1 and severe asthma exacerbation
The pandemic influenza A H1N1 will affect millions of subjects. This influenza can cause respiratory complications with possible death. We have described two case reports of acute severe asthma exacerbation combined to influenza A H1N1, caracterized by severe respiratory failure. The diagnosis of influenza A H1N1 was confirmed with the multiplex re....
When should a reversibility test be performed on patients with early stages of asthma and normal spirometry?
Subjects with bronchial asthmatic symptoms, forced expiratory volume in 1 second (FEV(1)) and FEV(1)/forced vital capacity [FVC] > 80% could show a positive reversibility test with salbutamol in about 25% of the cases. The aim of this study was to evaluate if a limit functional value for spirometry exists where a reversibility test using s....
Comparison of the protective effect amongst anticholinergic drugs on methacholine-induced bronchoconstriction in asthma
The protective effect of inhaled anticholinergic drugs in the methacholine-induced bronchospasm is well-known. The objective of this study was to assess if any possible differences may be found among Ipratropium (IB), Oxitropium (OXI) and Tiotropium (TIO) pre-treatments to obtain the protective effect. Forty-four patients with intermittent bronchia....
Short term effect of a single dose of formoterol or tiotropium on the isolated nocturnal hypoxemia in stable COPD patients: a double blind randomized study
Patients with stable chronic obstructive pulmonary disease (COPD) and diurnal PaO2 > 60 mmHg may have transient oxygen desaturation during sleep. The effect of bronchodilators on nocturnal hypoxemia is not known. The aim of this study was to evaluate if a single dose of Formoterol or Tiotropium, administered in the evening, could improve nocturn....
Oral corticosteroids can improve nocturnal isolated hypoxemia in stable COPD patients with diurnal PaO2 > 60 mmHg
'9The aim of this study was to evaluate whether a short therapy cycle of oral methylprednisolone plus conventional therapy might improve isolated nocturnal hypoxemia evidenced through pulse-oxymetry in 28 patients (19 M/9 F; mean age 71 +/- 8.31) with stable moderate to severe COPD (average FEV1 of 43.33 +/- 9.38 of theoretical) and daytime PaO2 &g....
Neurotrophin system expression in human pulmonary carcinoid tumors
Neurotrophin (NT) and NT receptor expression was assessed in 12 typical (TC) and 8 atypical (AC) human pulmonary carcinoids by Western blot and immunohistochemistry. TC and AC carcinoid express to different extent NT and NT receptor proteins. Nerve growth factor (NGF) was expressed by 83% of the TC but not by the AC carcinoids. Brain derived ....
Reversibility test in the early stages of bronchial asthma
In the early stages of bronchial asthma, it is frequent to find subjects with a positive history and an FEV1 or FEV1/FVC > 80% of the predicted value. This study investigated if the test of reversibility showed a reversible airway obstruction (RAO) in 291 subjects with the above clinical and functional features. Forced expiratory volume in 1 sec....
