The aim of this randomized, open, parallel group study was to compare the clinical efficacy of formoterol dry powder capsule 12 micrograms b.i.d. and salmeterol dry powder 50 micrograms b.i.d. in the treatment of patients with reversible obstructive airways disease. The 6-month treatment was preceded by a 2 week run-in period. Morning pre-dose peak expiratory flow (PEF) during the last 7 days of treatment was the primary variable. Throughout the study, patients recorded morning and evening pre-dose PEF, use of rescue medication, respiratory symptoms and adverse events. Clinic visits were scheduled at monthly intervals. Of the 482 patients randomized (equal numbers in the two treatment groups), 428 completed the study. Four hundred and twenty-five patients were included in the efficacy analysis for the primary variable. For mean morning pre-dose PEF during the last 7 days of treatment, the 95% confidence interval (CI) for the treatment contrast formoterol minus salmeterol was included entirely in the pre-defined range of equivalence (CI limits = -8.69, +9.841 min-1). This was also the case for the morning PEF during the last week before each clinic visit. For mean evening pre-dose PEF, the estimated treatment contrasts showed a trend towards superiority of formoterol over salmeterol, which became statistically significant at 2, 3 and 4 months (P < 0.05; estimated contrasts 7.27, 10.45 and 10.511 min-1, respectively). No treatment group differences were found in use of rescue medication and respiratory symptom scores. The incidence of adverse events was similar in the two groups. These findings demonstrate that formoterol 12 micrograms b.i.d. and salmeterol 50 micrograms b.i.d., both formulated as dry powders, have similar long-term efficacy and safety profiles in patients with reversible obstructive airways disease.

Since 2013, both hospitals' intravenous thrombolytic therapy program has been successfully applied as public health policy. A successful campaign on healthy lifestyle must be strengthened through a comprehensive approach with other public sectors in order to have an impact on the population, particularly in children and adolescents.

Objective The objective of the study was to measure the proportion of patients who consulted for headache and of those who had a final diagnosis of migraine. We also assessed the proportion and characteristics of patients with migraine and the impact of migraine on the daily activities and the professional and social lives of patients visiting private/public medical centers in Guatemala, Costa Rica, Panama, and the Dominican Republic. Background Underdiagnosis of migraine is high in Central America and Caribbean urban communities. However, there is limited knowledge on characteristics of headache disorders for the appropriate classification of migraine, which is a prerequisite for targeted treatment. Hence, there is a need to improve migraine awareness among patients and medical professionals in this region. Methods Central America and Caribbean countries epidemioLogy study of Migraine (CALM) was a non‐interventional, cross‐sectional, multinational study in adults aged 18–65 years with a history of or current headache. The primary outcome was the proportion of patients with migraine visiting medical centers due to headache disorders. Using a specially designed migraine survey questionnaire, patients self‐reported migraine characteristics, duration, and severity of attacks and impact on work and social life. Results Of the 313 enrolled patients, 308 (98.4%) completed the study. Approximately 75.3% (232/308) of patients with headache visiting medical centers had migraine, with episodic migraine being the most common (193 [83.2%]). Overall, 34/308 (11.0%) patients had a new diagnosis of migraine. Among patients with migraine, 66 (28.4%) had a history of migraine for ≥20 years and 59 (25.4%) experienced severe pain. Overall, 52.2% (121/232) of patients reported that migraine affected their professional life and 78.4% (182/232) reported an impact on social life. Conclusion The CALM study establishes that a high proportion of patients with migraine had a long duration and high severity of migraine attacks, leading to a direct impact on work/social life as well as on costs incurred by patients in these countries.

The prevalence of tobacco dependency in patients with persistent asthma is lower than in the population as a whole; over a third receive no counselling about giving up. Interventions must be conducted in still healthy smokers and chronically ill patients in both primary and specialist care.
