Chronic rhinosinusitis associated with chronic bronchitis in a five-year follow-up: the Telemark study.

Background: Chronic rhinosinusitis (CRS) is associated with generalised airway inflammation. Few studies have addressed the relationship between CRS and chronic bronchitis (CB).

Methods: This prospective study over a five-year period aims to investigate the risk of developing CB in subjects reporting CRS at the beginning of the study.

Non-infectious rhinitis is more strongly associated with early-rather than late-onset of COPD: data from the European Community Respiratory Health Survey (ECRHS).

Purpose: Chronic obstructive pulmonary disease (COPD) is associated with several co-morbidities and non-infectious rhinitis (NIR) has emerged as a new possible co-morbidity. The primary aim of this study is to confirm a previously reported association between NIR and COPD in a multicentre population over time. The secondary aim is to investigate the course over time of such an association through a comparison between early- and late-onset COPD.

New evidence of increased risk of rhinitis in subjects with COPD: a longitudinal population study.

Background: The aim of this population-based study was to investigate the risk of developing noninfectious rhinitis (NIR) in subjects with chronic obstructive pulmonary disease (COPD).

Materials And Methods: This is a longitudinal population-based study comprising 3,612 randomly selected subjects from Gothenburg, Sweden, aged 25-75 years. Lung function was measured at baseline with spirometry and the included subjects answered a questionnaire on respiratory symptoms.

Establishment of a validated training programme on the Eyesi cataract simulator. A prospective randomized study.

Purpose: To establish and evaluate a systematic training programme to be included into the ophthalmologic resident curriculum.

Methods: Medical students (n = 20) within a year from graduation and with no previous ophthalmic experience were included in this prospective study and randomized into two groups. Group A (n = 10) completed the Eyesi cataract simulator training programme once a week for 4 weeks, while Group B (n = 10) completed it once a week at the first and the last week.
