BACKGROUND Lung cancer is the commonest cause of cancer death in the UK. Patients generally present to their general practitioner, but the pathway of diagnosis from first symptom to diagnosis has not been mapped. We performed a cohort study of 246 patients with lung cancer in Exeter, Devon UK. All patients had their cancer symptoms, referrals and diagnoses identified and dated using their docto...
Hemoptysis can be defined as the expectoration of blood during coughing that originates from the lower respiratory tract. Per this definition, coughing of blood from an upper respiratory tract illness can be excluded. While coughing blood can be alarming to the patient, it is usually a self-limiting symptom. In clinical practice, only 5% of the patients who present with hemoptysis are found to ...
Diagnosis of asthma is often challenging in primary-care physicians due to lack of tools measuring airway obstruction and variability. Symptom-based diagnosis of asthma utilizing objective diagnostic parameters and appropriate software would be useful in clinical practice. A total of 302 adult patients with respiratory symptoms responded to a questionnaire regarding asthma symptoms and provokin...
The aim of this study was to determine whether impedance values in children with various chronic respiratory complaints differed from those observed in symptom-free children. Respiratory impedance was measured using the forced oscillation technique in 1,776 Dutch children aged 6-12 yrs. In addition to the commonly used parameters of resistance and reactance, further impedance parameters were ob...
Background and aims Exposure to flour dust and related allergens is one of the most common causes of occupational airway disease (OAD) and occupational asthma (OA). The main purpose of this study was to investigate the respiratory effects of exposure to high atmospheric concentrations of flour dust. Methods This study was carried out in a local flour producing factory in Shiraz, in 1384. Sixty...
BACKGROUND Acute bronchitis is one of the most prevalent respiratory infections in primary care, and in more than 90% of the cases antibiotics are prescribed, mainly when purulent expectoration is present. However, this process is usually viral in origin and the benefits of antibiotic treatment are marginal. On the other hand, in recent years bronchitis has been considered more as an inflammato...
BACKGROUND As part of the Respiratory Disease Specific Program (DSP) conducted to provide observations of clinical practice from a physician and matched patient viewpoint, this study aimed to establish how patients with COPD are treated according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification system and to quantify the symptom burden. METHODS Data were obt...
Longitudinal variability in respiratory responses, ineluding symptom reporting and across-shift change in ventilatory function, were examined in relation to long-term loss of ventilatory function in a group of 447 cotton textile workers in Shanghai, China. The study used a standardized respiratory questionnaire and standardized spirometric testing before and after a work shift on the first day ...
A rating procedure for respiratory disability has been developed; it entails measuring the symptom-limited maximal oxygen uptake or estimating the maximal uptake from the results of a submaximal exercise test and other relevant variables. The derivation assumes a linear scale of disability between the limits 0% and 100% which are defined. The percentage disability of 157 men with respiratory li...
BACKGROUND Patient-reported outcomes (PROs) are particularly relevant in influenza vaccine trials in the elderly where reduction in symptom severity could prevent illness-related functional impairment. OBJECTIVES To evaluate PROs in people aged ≥ 65 years receiving two different vaccines. METHODS This was a phase III, randomised, observer-blind study (NCT00753272) of the AS03-adjuvanted ina...
