RESUMO

Asthma is a highly prevalent condition across Europe and numerous guidelines have been developed to optimise management. However, asthma can be neither cured nor prevented, treatment choices are limited and many patients have poorly controlled or uncontrolled asthma. The Brussels Declaration on Asthma, sponsored by The Asthma, Allergy and Inflammation Research Charity, was developed to call attention to the shortfalls in asthma management and to urge European policy makers to recognise that asthma is a public health problem that should be a political priority. The Declaration urges recognition and action on the following points: the systemic inflammatory component of asthma should be better understood and considered in assessments of treatment efficacy; current research must be communicated and responded to quickly; the European Medicines Agency guidance note on asthma should be updated; "real world" studies should be funded and results used to inform guidelines; variations in care across Europe should be addressed; people with asthma should participate in their own care; the impact of environmental factors should be understood; and targets should be set for improvement. The present paper reviews the evidence supporting the need for change in asthma management and summarises the ten key points contained in the Brussels Declaration.

RESUMO

BACKGROUND: The Clinical Outcomes with Montelukast as a Partner Agent to Corticosteroid Therapy (COMPACT) trial demonstrated that montelukast added to budesonide (MNT + BD) was as efficacious as double the dose of budesonide (dBD) in improving morning peak expiratory flow (AM PEF) in adult asthmatics. Recent studies have demonstrated that montelukast is also effective in treating daytime and nighttime allergic rhinitis (AR) symptoms in asthmatic patients. This analysis was designed to examine whether asthmatic patients with comorbid AR respond differently than patients without comorbid AR in terms of asthma control (lung function). METHODS: There were 216 asthmatic patients in the MNT+BD group and 184 patients in the dBD group with AR. Treatment differences in the change from baseline in AM PEF were compared. Least square (LS) mean and 95% confidence interval (CI) were derived from an anova model adjusting for baseline and study site. RESULTS: There was a 9.2% increase in AM PEF from baseline in the MNT+BD group compared with a 6% increase in the dBD group. The LS mean difference [(MNT+BD)-dBD] was 14.2 l/min (P=0.028). Other secondary endpoints were similar between groups. CONCLUSION: In the subgroup of asthmatic patients with AR, a combined treatment approach that included montelukast and budesonide provided significantly greater efficacy in reducing airflow obstruction compared with doubling the dose of budesonide. These results support recommendations by the Allergic Rhinitis and its Impact on Asthma initiative that suggest a unified approach aimed at treating the airway inflammation common to both diseases is beneficial for the large proportion of asthmatics who also suffer from AR.

RESUMO

BACKGROUND: Inhaled corticosteroids (ICS) affect many inflammatory pathways in asthma but have little impact on cysteinyl leukotrienes. This may partly explain persistent airway inflammation during chronic ICS treatment and failure to achieve adequate asthma control in some patients. This double blind, randomised, parallel group, non-inferiority, multicentre 16 week study compared the clinical benefits of adding montelukast to budesonide with doubling the budesonide dose in adults with asthma. METHODS: After a 1 month single blind run in period, patients inadequately controlled on inhaled budesonide (800 microg/day) were randomised to receive montelukast 10 mg + inhaled budesonide 800 microg/day (n=448) or budesonide 1600 microg/day (n=441) for 12 weeks. RESULTS: Both groups showed progressive improvement in several measures of asthma control compared with baseline. Mean morning peak expiratory flow (AM PEF) improved similarly in the last 10 weeks of treatment compared with baseline in both the montelukast + budesonide group and in the double dose budesonide group (33.5 v 30.1 l/min). During days 1-3 after start of treatment, the change in AM PEF from baseline was significantly greater in the montelukast + budesonide group than in the double dose budesonide group (20.1 v 9.6 l/min, p<0.001), indicating faster onset of action in the montelukast group. Both groups showed similar improvements with respect to "as needed" beta agonist use, mean daytime symptom score, nocturnal awakenings, exacerbations, asthma free days, peripheral eosinophil counts, and asthma specific quality of life. Both montelukast + budesonide and double dose budesonide were generally well tolerated. CONCLUSION: The addition of montelukast to inhaled budesonide is an effective and well tolerated alternative to doubling the dose of inhaled budesonide in adult asthma patients experiencing symptoms and inadequate control on budesonide alone.

RESUMO

The aim of this study was to assess changes in the costs of asthma drug therapy before and during the use of chronic montelukast treatment in the U.K. A retrospective cohort analysis of a primary care database in the U.K. was carried out. Patients with chronic montelukast use (> or = 140 once-daily doses) were selected for analysis. Benchmarking data were obtained for matched patients with chronic inhaled corticosteroid (ICS) use and patients with chronic salmeterol therapy with concomitant ICS use. The main outcome measures were changes in utilization and monthly cost of asthma therapies costs. Asthma patients experienced significant (P<0.05) reductions in the monthly costs of ICS, short-acting beta-agonists and antibiotics following chronic montelukast therapy. Monthly concomitant drug costs were reduced by Pound Sterling 7.49 per month, which offset 27.5% of the additional cost of montelukast, yielding an increase in total drug costs of Pound Sterling 19.78 per month. Meanwhile, increased total drug costs for matched patients with chronic ICS use, and matched patients with chronic salmeterol therapy and concomitant ICS use, increased by Pound Sterling 5.37 per month and Pound Sterling 44.55 per month respectively. Additionally, patients using chronic montelukast therapy experienced a statistically significant (P<0.05) reduction in the use of short acting beta-agonists, and antibiotics, suggesting improvement in asthma control. Chronic use of montelukast therapy is associated with a reduction of concomitant drug therapy costs.

RESUMO

The sacrum is a structure that is imaged by both general and subspecialty radiologists. A wide variety of disease processes can involve the sacrum either focally or as part of a systemic process. Plain radiographs, although limited in evaluation of the sacrum, should be carefully examined when abnormalities of the sacrum are suspected. Cross-sectional imaging, particularly computed tomography and magnetic resonance (MR) imaging, plays a crucial role in identification, localization, and characterization of sacral lesions. Congenital lesions of the sacrum, including sacral agenesis and meningocele, are optimally imaged with MR. The most common sacral neoplasm is metastatic disease. Primary neoplasms of the sacrum, which include giant cell tumor, chordoma, and teratoma, are infrequent. Infection of the sacrum or sacroiliac joint is most often due to contiguous spread from a suppurative focus. A wide variety of arthritic disorders such as ankylosing spondylitis and osteoarthritis can involve the sacroiliac joints as part of a localized or systemic process. Sacral fractures related to acute trauma or repetitive stress are difficult to diagnose and treat. Knowledge of these abnormalities and familiarity with the imaging of these processes will allow radiologists of all subspecialties to contribute to the diagnosis and management of sacral disorders.

RESUMO

This study compared the handling and acceptability of the Easi-Breathe, a breath-actuated metered dose inhaler (MDI), with that of a conventional MDI. A total of 104 patients and 14 practice nurses took part in interviews at a central location. An additional 100 practice nurses were interviewed in a telephone study. Significantly more patients (86%) found Easi-Breathe easier than a conventional MDI to use correctly (p < or = 0.001). Overall, more patients preferred Easi-Breathe (82% vs 18%; p < or = 0.001), ease of use and confidence in successful dose delivery being the main reasons for their preference. Nurses thought that Easi-Breathe was easier for the vast majority of patients (97%) to use correctly, as well as being easier to teach and to use correctly in a crisis (p < or = 0.001). Overall, 79% of nurses preferred the Easi-Breathe to the conventional MDI (p < or = 0.001), ease of use and ease of teaching being the main reasons for their preference.

RESUMO

This study compared, for the first time in the United Kingdom, the efficacy and safety of oral 100 mg and subcutaneous 6 mg sumatriptan within a patient for the acute treatment of migraine. The patient's preference for the two formulations of sumatriptan were also recorded. The study was a multicentre, randomized, open, crossover design with an optional open parallel group extension. Individual attacks were treated with one formulation only. Over 70% of patients who treated attack 1 in both treatment periods of the crossover phase reported headache relief with each formulation at 4 h. Only 3% of patients failed to respond to at least one of the formulations at this time point. At the end of the crossover phase patient preference for the injection more than doubled from the pretreatment level in those patients who were previously naive to sumatriptan. During the optional phase of the study, 38% of patients chose to treat some attacks with oral and some with subcutaneous sumatriptan. The main reason for choosing injection was speed of relief, whilst convenience was the major reason for the use of the tablet.

RESUMO

OBJECTIVE: A small subset of posterior inferior cerebellar artery (PICA) aneurysms arise distal to the vertebral artery origin of the PICA. We present two such cases seen on conventional angiography and MR angiography (MRA). MATERIALS AND METHODS: The findings in two patients are presented. In one the aneurysm presented with subarachnoid hemorrhage. The second was found incidentally but later ruptured. RESULTS: There was good agreement between the appearance of the aneurysms on MRA and conventional angiography. CONCLUSION: Awareness of the possibility of peripheral PICA aneurysms and their features is important. The positioning of the volume of excitation for MRA may have to be adjusted to include a very low PICA caudal loop.

RESUMO

Detection of a nondistended pyriform sinus on cross-sectional imaging studies represents a diagnostic dilemma. The finding may be an inconstant physiologic phenomenon without clinical significance, or it may be due to tissue thickening and lack of pliability related to neoplasia or inflammation. Rescanning during respiratory maneuvers may clarify the anatomy, but full patient cooperation is needed. We demonstrate a method (turning the patient's head away from the side of the nondistended sinus) that induces distention of the pyriform sinus but does not require active patient participation.
