Emphysema and Airway Wall Thickness affect Mortality

emphysema airway wall thickness
  Although computed tomography (CT) has been used to measure the thickness of airway walls (AWT) and degree of emphysema, the prognostic value of these CT measures on morality had never been studied before. A recent study, published in the latest issue of American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, has found the association between CT- measured emphysema and AWT and eight years mortality.   The study was led by Ane Johannessen, a post-doctoral...

Patients of COPD show marked improvement with the use of Lung Flute

copd
Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a disease of the lungs characterized by hyper-secretion of mucus. The disease is often seen in chronic smokers and is the third leading cause of death in the U.S. A new hand-held respiratory device called as the Lung Flute, which produces a low frequency acoustic wave and allows the patient to clear the mucus in his lungs by simply blowing into it, has been found to be of great help in patients...

Lung Ultrasound: Aurora Sign and Parenchymal Lung Disease

Multiple ring-down artefacts (RA) can be seen on the dorsal side of right hepatic lobe on abdominal ultrasound examination. These artefacts are normally noted in the subcostal or intercostal views. When these ring-down artefacts are numerous, they are termed as aurora sign or retrohepatic diffuse hyperechogenicity. The high echo bands that occur in the dorsal side of the right hepatic lobe 3 to 10 mm wide and 30mm or greater in length were defined as ring-down artefacts. To qualify for the term...

Prevalence of Asthma reaches All Time High

  More people have been diagnosed with asthma in 2010 than ever before. 8.4% of the U.S. population was affected by asthma in 2010 compared to 7.3% in 2001. This means that about 18.7 million adults and 7 million children were either diagnosed with asthma or were suffering from the condition in 2010. The figures form a part of a report called as Asthma’s Impact on the Nation released by the Centers of Disease Control and Prevention (CDC).   Although the number of patients suffering from...

Tiotropium reduces mortality in COPD patients

hpe of emphysema
The beneficial effects of tiotropium, a long acting antimuscarinic agent (LAMA) in COPD patients has been previously shown in a large trial (UPLIFT trial). UPLIFT, an acronym for ‘Understanding Potential Long Term Impacts on Function with Tiotropium’ established tiotropium as one of the primary drugs in the management of COPD patients. A recent retrospective study with a mean follow up period of 4.65 years from the University of Dundee also attests to the usefulness of tiotropium....
