Filter by:Consultations with patients by hospital consultants are organised today in a manner which is barely dissimilar from that offered 30 or 40 years ago. Whilst some attempts to improve this process, such as Choose and Book, shorter waiting times and patients' receiving a copy of the correspondence sent to their general practitioner (GP) have improved the situation, there has been little radical change and little thought given to the patient experience. The investigators wish to investigate whether patients' experience of attending respiratory outpatient clinics can be improved by a pre-clinic telephone call with a specialist thereby reducing the number of attendances at the hospital for appointments and investigations and improving overall patient satisfaction.
The purpose of this research study is to collect cells and liquid from the air passages of healthy adults, both smokers and non-smokers. These samples will be used for test-tube studies to explore mechanisms of diseases of the respiratory tract, and to compare the samples between people who smoke cigarettes and people who don't. Obtaining these samples requires an invasive procedure called "bronchoscopy".
Probiotics has been known as a dietary supplement for a long period. Recent clinical trials indicate that probiotics might have an effect in preventing common infection diseases in children. The investigators hypothesis is: if young children in the age of 6 month to 15 mdr. has a daily intake of a suspension containing probiotics in a period of 9 months, the incidence of diarrhoea and respiratory diseases can be reduced.
Vibration Response Imaging (VRI) is novel technology which records breath sounds via pizo-electric sensors and produces a digital image using a computer algorithm. It is radiation free and is portable to the patient's bedside. Data exists to show that the recordings from normal individuals differs from those who have pulmonary pathology. There is also evidence that recordings have high levels of inter and intra-observer reliability. However, data on specific VRI patterns for specific pathology is still needed before this can be used as a diagnostic tool. We aim to perform an open label feasibility trial on inpatient and outpatient pulmonary patients. Bedside clinical examination and chest auscultation will be used as the reference gold standard. Other diagnostic modalities that have been used as part of the patient's usual standard of care will also be used for comparison. Specifically breath sound progression, the maximal sound energy shape/distribution and the presence of artifactual sounds will be used to search for patterns that may be used for diagnosis. Sensitivity and specificity will be calculated for each disease (eg. asthma, emphysema, bronchiectasis, pneumonia, effusion, pneumothorax, etc)
Increase in body mass index (BMI)is associated with a decrease in expiratory flows.Obesity is also associated with an increased prevalence of asthma.Consequences of obesity on respiratory function and on bronchial responsiveness are still to be documented. This study aims to evaluate, before and after surgery, the impact of a bariatric surgery (biliopancreatic diversion with duodenal switch)on respiratory function in patients with morbid obesity . Our hypothesis is that weight loss following bariatric surgery will induce significant improvements in pulmonary function and airway responsiveness, and, as a consequence, a reduction in respiratory symptoms,these changes being correlated with a reduction in systemic markers of inflammation. Maintenance of weight loss after one year will permit the persistence of these improvements
