COPD and mood disorders, part 2:Sleep problems
April 1st 2007Sleep complaints are common in patients with chronic obstructive pulmonary disease (COPD). Many patients complain of morning tiredness, early awakenings, difficulty in falling asleep, restlessness, and daytime sleepiness. Functional status may eventually be impaired by the resulting chronic fatigue that is compounded by dyspnea.
Exercise intolerance in severe COPD: A review of assessment and treatment
May 1st 2006Abstract: Exercise intolerance is common in persons with chronic obstructive pulmonary disease and can result from multiple physiologic factors, including dynamic hyperinflation, gas exchange abnormalities, and pulmonary hypertension. In the initial assessment, keep in mind that many patients underestimate the degree of their impairment. The 6-minute walk test is very useful in assessing the degree of exercise intolerance; when more extensive assessment is indicated, cardiopulmonary exercise testing (CPET) is the gold standard. CPET is particularly useful for defining the underlying physiology of exercise limitation and may reveal other causes of dyspnea, such as myocardial ischemia or pulmonary hypertension. Strategies for improving exercise tolerance range from the use of bronchodilators and supplemental oxygen to participation in a pulmonary rehabilitation program. (J Respir Dis. 2006;27(5):208-218)
Community-Acquired Pneumonia in the Elderly:
May 1st 2003ABSTRACT: In addition to advanced age, factors such as comorbid illness and debility determine the risk of community- acquired pneumonia (CAP). Many elderly persons do not have the classic symptoms of CAP; instead, they may present with confusion, lethargy, tachypnea, anorexia, or abdominal pain. Even with thorough investigation, an infectious pathogen can be identified in only about half of patients. In addition to the causative organisms for pneumonia in younger adults, elderly persons are at risk for infection with organisms such as Haemophilus influenzae, Staphylococcus aureus, enteric gram-negative bacteria, and anaerobes, and for polymicrobial infection. Prompt empiric treatment is essential. Recommended initial therapy choices include a ß-lactam agent with a macrolide, or an antipneumococcal fluoroquinolone.
