Authors: Precioso, J; Samorinha, C; Macedo, M; Antunes, H Abstract: Abstract INTRODUCTION: According to the MPOWER approach adopted in 2008 by the WHO, monitoring smoking epidemics is necessary in order to assess the effectiveness of the preventive measures used in smoking control in adolescents and adults. OBJECTIVES: To determine the prevalence of smoking in Portuguese school-aged adolescents by region. MATERIAL AND METHODS: The sample is made up of 8764 students, 4060 boys and 4704 girls, and is representative of the Portuguese students in regular public education. The data was collected in the 2008/2009 academic year, through a quantitative self-report questionnaire. RESULTS: In the total sample, 10.2% of boys and 9.1% of girls are regular smokers. Smoking increases with age. At 15 years old 12.3% of the boys and 8.6% of the girls are regular smokers and 6.1% of the boys and 4.0% of the girls are occasional smokers. Looking at prevalence by region, the highest prevalence of regular smoking is found in Alentejo (14.7%), followed by Azores (11.8%) and the lowest is found in Algarve (4.1%). CONCLUSIONS: The prevalence of smokers among Portuguese school-aged adolescents varies within the several regions of the country, similar to what happens in the adult Portuguese population. 2012-01-01T00:00:00Z http://comum.rcaap.pt/handle/123456789/2515 Title: Sedation with midazolam in flexible bronchoscopy - a prospective study Authors: Rolo, R; Mota, PC; Coelho, F; Alves, D; Fernandes, G; Cunha, J; Hespanhol, V; Magalhães, A Abstract: INTRODUCTION: Sedatives have been increasingly used to improve patient comfort during flexible bronchoscopy (FOB). Due to its rapid-onset, anxiolytic and amnestic properties, midazolam is one of the most commonly used sedatives. OBJECTIVES: To evaluate the effect of sedation with midazolam, including patient tolerance, complications and its potential use on a daily routine basis. MATERIAL AND METHODS: A multi-centre, prospective, randomized, placebo-controlled study was made on 100 patients submitted to FOB in two Pulmonology Departments. Midazolam (0.05mg/kg) was administered to patients in Group 1 and saline solution (0,9% NaCl) to patients in Group 2, five minutes before the procedure. The Hospital Anxiety and Depression Scale (HADS-A) was used to determine patient anxiety level. Subjective questionnaires concerning main fears and complaints were answered before and after FOB. RESULTS: Mean age was 56.0 ± 14.1 years; 66% male. Most (65%) patients had low score (<7) in HADS-A scale with no difference between groups. No significant differences were seen between groups concerning FOB duration, procedures, lidocaine dosage and complications. Systolic blood pressure during and after FOB was significantly higher (p<0.003) in Group 2. Patients in Group 1 experienced less cough (32% vs 56%; p=0.03) and dyspnea (2% vs 34%; p<0.001) than in Group 2, while nausea (6% vs 18%; p>0.05) and pain (4% vs 12%; p>0.05) were not statistically different. Willingness to repeat the exam was reported in all patients in Group 1 and in 82% in Group 2 (p=0.003). CONCLUSION: Sedation with midazolam in FOB improved patient's comfort and decreased complaints, without significant haemodynamic changes. It should be offered to the patient on a routine basis. 2012-01-01T00:00:00Z http://comum.rcaap.pt/handle/123456789/2149 Title: Implicações terapêuticas do lobo da veia ázigos em doente com adenocarcinoma do pulmão Authors: Pinto, CS; Santos, N; Alves, D; Cunha, J; Miranda, J; Vouga, L 2009-01-01T00:00:00Z http://comum.rcaap.pt/handle/123456789/2035 Title: Crohn's disease and intestinal tuberculosis: A clinical challenge.
