  • Comments and queries
    Rajendra K Sinha

    Dear Editor,

    Thanks to all concerned for putting together a very useful and long awaited guideline. I have the following questions and comments.

    1. What does "All Patient Rate" in table 3B mean and when should one use it, if at all for UK born patients (say white) as opposed to table 3A?

    Does a UK born white of 75 have a risk of 11 (Table 3A) or 4 (Table 3B - All patient rate column)?

    2. I...

  • Early Diagnosis Lung Cancer
    Virginia Capozi

    My mother had a yearly chest x-ray in March 2003 which then showed a mild kyphotic deformity in her thorax. In June 2004 she had another yearly x-ray which showed a left hilar mass lesion. Needless to say a week later she had a CT scan which showed that the cancer had metastized to her adrenal glands and she also had numerous lesions on her liver. As a physician would the kyphotic deformity be an indication to take fu...

  • Molecular markers in exhaled air in asthma
    Chiara Zinelli

    Dear Sir,

    We have read with interest the paper of Battaglia et al.[1] regarding the relationship between small airways function and molecular markers of inflammation in exhaled air in mild asthma. They concluded that fractional exhaled nitric oxide (FeNo) and 8-isoprostane in exhaled air reflect small airway inflammation, and that 8-isoprostane particularly is increased in patients with more prominent airway closure....

  • Beta agonists and coronary vascular events in asthmatics
    Raghupathy Anchala

    Dear Editor,

    We read with great interest the article by Schanen[1] et al. - Asthma and incident cardiovascular disease in which the authors have shown an association between multivariate adjusted Hazard ratio and incident stroke, but, not with Coronary heart disease in both model 1 and 2. One of the most important risk factors for coronary heart disease in asthmatics identified so far is the use of inhaled short-ac...

  • Role biological dust and female gender in COPD
    Bill B Brashier

    Dear Editor,

    Matheson et al., in their article had shown that the occupational exposure to biological dust was more associated with increased risk of respiratory symptoms and COPD than the mineral dust and gas fumes. We suppose that the subjects who had shown both mineral dust or gas and biological dust exposure together in their occupational history could have confounded these results.

    The statement that...

  • COPD and polyunsaturated fatty acids
    Undurti N Das

    Dear Editor,

    I read with interest the study by Broekhuizen et al. in which they described the beneficial effect of n-3 EPA/DHA. This reminded me of my own study done few years back on the possible beneficial action of n-3 PUFAs in bronchial asthma. In this study, I observed that asthmatics supplemented with n-3 PUFAs had fewer episodes of asthmatic attacks and the attacks tended to be mild. At that time, I thought...

  • Author's reply: what a whopper!
    Don D. Sin

    We thank Dr. O'Driscoll for alerting us to an error in the text. The correct figure for the worldwide mortality from lung cancer in 2000 was 0.85 million, not 328 million as originally stated in the article.

  • Quality of life in IPF patients, effect of the duration of the disease
    Nikolaos Tzanakis

    Dear Editor,

    We read with particular interest an excellent paper of Swigris et al.[1] systemically reviewed the published literature, to 1 April 2004, on the important issue of health-related quality of life (HRQL) in patients with idiopathic pulmonary fibrosis (IPF). We recently published a study (2) investigated HRQL impairment of 25 patients with histologically proven IPF using 3 HRQL questionnaires, 1 generic:...

  • What a whopper!
    B. Ronan O'Driscoll

    Dear Editor,

    Wassawa-Kintu and colleagues have performed a useful meta-analysis of the effect of reduced FEV1 on the risk of developing lung cancer. However, the authors, reviewers and editors failed to notice a major error of fact which is repeated in the "Airwaves" section of the journal. They stated in both articles that 328 million people died of lung cancer in 2000.

  • Asthma and allergies are increasing in some populations in Germany
    Wasim Maziak

    Dear Editor,

    We read the study by Zollner and colleagues published recently in Thorax about the leveling off of asthma and allergies among children in Germany between 1992 and 2001.[1] We have published a study looking at the same issue and using much of the same methodology (ISAAC) to assess asthma and allergies symptoms, diagnosis, and severity in more than 15,000 children (6–7 and 13–14 year olds) between 199...
