Effective management of dyspnea in chronic obstructive pulmonary disease (COPD) requires a clearer understanding of its underlying mechanisms. This roundtable reviews what is currently known about the neurophysiology of dyspnea with the aim of applying this knowledge to the clinical setting. Dyspnea is not a single sensation, having multiple qualitative descriptors. Primary sources of dyspnea i...
A 54-year-old woman with myoepithelioma, a very rare tumor of the lung, is reported. The patient presented with exertional dyspnea, cough and intermittent pleuritic chest pain. Her chest X-ray revealed a peripheral 2 cm mass in the left lower lung zone. Bronchoscopy was normal. She underwent thoracotomy in which a wedge-resection was performed. Histological examination of the specimen demonstra...
We report a case of a 70-year-old woman who presented with mild exertional dyspnea and cough. Fiberoptic bronchoscopic findings revealed an endobronchial polypoid lesion with stenotic bronchus. The lesion was very similar to endobronchial tuberculosis. Histologic examination of the biopsy specimen demonstrated Actinomyces infection. There was a clinical response to intravenous penicillin therap...
[Purpose] The current study aimed to investigate factors affecting dyspnea after the 6-minute walk test (6MWT) in idiopathic pulmonary fibrosis (IPF) patients presenting with hypoxemia. [Subjects and Methods] The subjects were IPF out-patients with stable symptoms whose percutaneous arterial oxygen saturation fell to 88% during the 6MWT test. Quadriceps force, 6-minute walk distance (6MWD), dys...
A 22-year old woman visited the LAMB Hospital, Parbatipur, Dinajpur, Bangladesh, in February 2010, with exertional dyspnea for three weeks. She had had a normal vaginal delivery four months ago; 2-dimensional echocardiogram showed severe left ventricular dysfunction and biventricular thrombi, which resolved without complications after anticoagulation. Biventricular thrombosis with peripartum ca...
This report describes a patient who developed pulmonary hypertension 6 years after lung transplantation for primary pulmonary hypertension (PPH). Evaluation with right heart catheterization followed by pulmonary angiography, however, demonstrated that the pulmonary hypertension was secondary to an anastomotic narrowing of the pulmonary artery, rather than a recurrence of her PPH. Vascular compl...
A 35 year old male, known case of corrected transposition of great arteries presented with exertional dyspnea and recurrent pre-syncope. 12 lead electrocardiogram revealed a regular rhythm at 75 beats per minute, P waves occurring on the upstroke of T waves and apparent 1:1 P-QRS relationship. The possibilities to be considered - complete AV block with junctional escape, junctional rhythm with ...
It is rare that amyotrophic lateral sclerosis (ALS) presents with respiratory failure as the sole initial manifestation. A 72-year-old man with mild chronic obstructive pulmonary disease developed exertional dyspnea for 13 months. He then progressed to limb weakness that led to the diagnosis of ALS. Although rare, ALS can present with respiratory failure as the sole initial manifestation more t...
