Effect of Salmeterol on Seasonal Changes in Airway Responsiveness and Exhaled Nitric Oxide in Pollen-Sensitive Asthmatic Subjects
2002
Objective Using a model of natural allergen exposure, we examined the effect of regular treatment with salmeterol on allergen-induced changes in airway responsiveness and exhaled nitric oxide (ENO). Design Double-blind, randomized, parallel-group study. Setting Specialist allergy unit in a university hospital. Patients Asthmatic patients sensitized to pollen allergens were randomly allocated to monotherapy with salmeterol (n = 14) or placebo (n = 13). Interventions Salmeterol, 25 μg, and placebo inhalers, two puffs bid, for 6 weeks. Measurements Spirometry, the level of a provocative concentration of a substance (methacholine) causing a 20% fall in FEV 1 (PC 20 ), the PC 20 level for adenos…
Effect of QVA149 on lung volumes and exercise tolerance in COPD patients: The BRIGHT study
2014
Summary Introduction QVA149 is a novel, inhaled, once-daily dual bronchodilator containing a fixed-dose combination of the long-acting β 2 -agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium (NVA237), for the treatment of chronic obstructive pulmonary disease (COPD). This study evaluated the effects of QVA149 on exercise tolerance, hyperinflation, lung function and lung volumes versus placebo and tiotropium. Methods Patients with moderate-to-severe COPD were randomized to QVA149 110/50 μg, placebo or tiotropium 18 μg once daily in a blinded, 3-period crossover study for 3 weeks. The primary endpoint was exercise endurance time at Day 21 for QVA149 versus placebo. R…
A randomized, double-blind study to compare the efficacy and safety of two doses of mometasone furoate delivered via Breezhaler® or Twisthaler® in pa…
2019
Abstract Introduction Mometasone furoate (MF) is the inhaled corticosteroid (ICS) component in the long-acting β2-agonist (LABA)/ICS fixed-dose combination of indacaterol/MF, delivered via Breezhaler®, in development for asthma. MF at low (80 μg) and high (320 μg) doses delivered via Breezhaler® is expected to be comparable to MF at low (200 μg) and high (800 μg) doses respectively, delivered via Twisthaler®. Methods This was a randomized, double-blind, double-dummy, four-week, parallel-group study of 739 adolescents and adults with persistent asthma. Eligible patients were receiving ICS treatment up to the maximum dose per day on a stable regimen for at least four weeks before screening. T…
Preference for Rizatriptan 10-mg Wafer vs. Eletriptan 40-mg Tablet for Acute Treatment of Migraine
2006
Preference is a composite, patient-oriented endpoint incorporating efficacy, tolerability, formulation, and convenience of medications. The objective of this study was to compare patient preference for rizatriptan 10-mg wafer vs. eletriptan 40-mg tablet for acute treatment of migraine. In this multicentre, open-label, two-period, crossover study, out-patients were randomly assigned to treat the first of two moderate to severe migraines with rizatriptan or eletriptan and the second with the alternate therapy. Patients completed diary assessments at baseline and up to 24 h after taking study medication. At the last visit, patients completed a psychometrically validated preference questionnai…
Influence of Refraction on Tonometric Readings After Photorefractive Keratectomy and Laser Assisted In Situ Keratomileusis
2000
PURPOSE To determine the decrease of Goldmann tonometry after photorefractive keratectomy (PRK) and laser assisted in situ keratomileusis (LASIK) according to refraction prior to surgery. METHODS Prospective simultaneous comparative case series of 53 myopic eyes (53 patients) that underwent PRK and 50 (50 patients) that underwent LASIK using the Summit Excimed SVS plus (Summit Technology, Inc., Walthan, MA, U.S.A.). PRK and LASIK were subdivided by refractive error into two subgroups of more than or less than -5 diopters (D). Central tonometric readings were taken prior to surgery and 12 months after surgery. RESULTS In LASIK and PRK subgroups of more than -5 D, 85.7% (24) and 69.6% (24), r…
Low rectal cancer: abdominoperineal resection or low Hartmann resection? A postoperative outcome analysis.
2011
BACKGROUND In distal rectum cancers, when the sphincters are not affected and it is not possible to perform a coloanal anastomosis because of the presence of comorbidities or the advanced age of the patient, a low Hartmann resection with total mesorectal excision can be performed. Low Hartmann resection is usually considered to be a shorter procedure and to have an inferior morbidity compared with abdominoperineal resection of the rectum. OBJECTIVE This study aimed to compare the postoperative outcome of a series of patients with low rectal cancer who have undergone either low Hartmann resection or abdominoperineal resection. DESIGN This study is a retrospective analysis of data collected i…
Serotonergic modulation of response inhibition and re-engagement? Results of a study in healthy human volunteers
2010
Objective Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and initiate a new one (response re-engagement) is important in the activities of daily life. Central serotonin (5-HT) function is thought to be a critical component of these cognitive functions. In recent studies, 5-HT failed to affect stop-signal reaction time (SSRT), a fundamental process in behavioral inhibition. We were interested if response inhibition and re-engagement are influenced through central 5-HT activity as mediated via the 5-HT transporter. Methods Here, using a stop-change task, we investigated the effects of acute and repeated treatment with 10 …
Distribution of liver disease in a cohort of immigrants in Sicily: analysis of day-hospital admissions in a migration medicine unit.
2014
The objective of this study was to evaluate the frequency of liver disease and its aetiology in a cohort of immigrants. We retrospectively examined the hospital discharge charts of all the immigrant patients presenting at our day hospital from July 2009 to June 2013, and after evaluating the anamnestic, clinical and laboratory data on these charts we identified subjects with liver disease and its various aetiologies. The total sample population consisted of 1218 patients, of whom 112 (9.2%) had a diagnosis of liver disease. More than two-thirds of the latter (67.8%) came from Africa, while 15.2% were from Asia and 17.0% from Eastern Europe. In most patients the disease was related to HBV (4…
Shape change in the atlas with congenital midline non-union of its posterior arch: a morphometric geometric study.
2017
Background Context The congenital midline non-union of the posterior arch of the atlas is a developmental variant present at a frequency ranging from 0.7% to 3.9%. Most of the reported cases correspond to incidental findings during routine medical examination. In cases of posterior non-union, hypertrophy of the anterior arch and cortical bone thickening of the posterior arches have been observed and interpreted as adaptive responses of the atlas to increased mechanical stress. Purpose We sought to determine if the congenital non-union of the posterior arch results in a change in the shape of the atlas. Study Design/Setting This study is an analysis of the first cervical vertebrae from osteo…
Melperone is an Inhibitor of the CYP2D6 Catalyzed O-demethylation of Venlafaxine
2003
INTRODUCTION Melperone, a butyrophenone neuroleptic, is frequently used for its sleep-inducing properties. Despite its common use for more than 30 years, it is not yet characterized regarding its effects on cytochrome P450 s (CYPs). In an open pilot study, effects of melperone on the steady-state blood levels of venlafaxine, a recently introduced serotonin- and noradrenaline reuptake inhibiting antidepressant, were assessed. METHODS The dose-corrected serum concentrations of venlafaxine and O-desmethylvenlafaxine were analyzed retrospectively in a therapeutic drug-monitoring (TDM) database comprising 94 patients. In addition, three patients received venlafaxine and melperone concomitantly a…
