A 51-year-old woman with chronic obstructive pulmonary disease presents with nonproductive cough and slowly progressive dyspnea of 3 months' duration. She denies fever, chills, and night sweats. Over the past 3 months, she has received several different courses of treatment; the latest was cefixime, a 2-week tapering dose of prednisone, and bronchodilators. These treatments have failed to alleviate her symptoms.

Guidelines for the management of community-acquired pneumonia (CAP) have been published by several medical organizations, including the British Thoracic Society, the American Thoracic Society, and the Infectious Diseases Society of America (IDSA). Do these guidelines help improve survival rates? Yes, according to a study that focused on adherence to the IDSA guidelines and outcomes for patients with severe CAP. This study also underscores the importance of providing adequate coverage for Pseudomonas aeruginosa in patients with risk factors such as chronic obstructive pulmonary disease (COPD), malignancy, or recent antibiotic treatment.

Abstract: Smoking cessation is still the most important intervention in patients with chronic obstructive pulmonary disease (COPD), regardless of sex. There is some evidence that nicotine replacement therapy may be less effective in women than in men. However, women may derive greater benefits from a sustained quit attempt. For example, one study found that compared with men, women who were sustained quitters had a greater initial rise and a slower age-related decline in forced expiratory volume in 1 second. Men and women do not appear to differ in their response to bupropion or to the various types of bronchodilators. A number of factors contribute to the increased risk of osteoporosis in women with COPD. Both smoking and the degree of airflow obstruction have been identified as important risk factors for osteoporosis. Women may be particularly susceptible to the effects of smoking on bone metabolism. Immobility and decreased physical activity have also been shown to accelerate bone loss. (J Respir Dis. 2006;27(3):115-122)

A number of studies have found an increased prevalence of anxiety and depression in patients with asthma and chronic obstructive pulmonary disease (COPD). Although the relationship is not completely understood, it is clear that psychological disorders can adversely affect the course of both diseases.

Abstract: The increase in cigarette smoking among women is now being reflected in an increased incidence of chronic obstructive pulmonary disease (COPD). Since 1985, the rate of COPD-related deaths in women has steadily risen, and it nearly tripled from 1980 to 2000. There continues to be debate about whether women are more susceptible than men to COPD. Women on average have airways that are 17% smaller, and further narrowing of the airways by COPD may make women more vulnerable to symptomatic airways obstruction. There also is some evidence of greater bronchial hyperreactivity in women, although conflicting findings have been reported. Gender bias appears to exist in the diagnosis and workup of COPD. For example, there is some evidence that clinicians are more likely to consider the diagnosis of COPD in men than in women. One study showed that women who had symptoms consistent with COPD were significantly less likely than men to undergo spirometric assessment. (J Respir Dis. 2006;27(2):70-74)

Abstract: A number of factors complicate the diagnosis of asbestos-related pulmonary diseases. Most persons who have had heavy exposure to asbestos are now aged at least 65 years and, therefore, are more likely to have other respiratory problems, such as chronic obstructive pulmonary disease, that may be difficult to differentiate from asbestosis. An accurate assessment of exposure history is particularly challenging because of poor recall of events by patients and because critical variables, such as fiber type, size, and length, can be difficult to evaluate. High-resolution CT (HRCT) has better sensitivity and specificity for asbestos-related pleural disease and neoplasms than does chest radiography. However, HRCT findings in patients with asbestosis are relatively nonspecific. Bronchoalveolar lavage and lung biopsy can provide definitive information about the extent of asbestos exposure.

In patients with underlying disease, a preoperative evaluation and targeted perioperative management strategies can minimize surgical complications and maximize healing. This article focuses on how to identify surgery patients at risk for complications caused by diabetes, chronic obstructive pulmonary disease (COPD), and other medical conditions; I also describe strategies to minimize such risk.

A 72-year-old morbidly obese man who had diabetes mellitus was admitted to the hospital from a nursing home with a fever of 4 days' duration. A tracheostomy had been performed 3 months earlier for respiratory failure. The patient was being treated with corticosteroids for chronic obstructive pulmonary disease.

A 56-year-old man was admitted to the hospital with right lower lobe pneumonia, which was exacerbated by smoking-induced chronic obstructive pulmonary disease (COPD).

For 1 month, a 66-year-old man had had an asymptomatic lesion on the dorsum of his left hand. The flesh-colored, dome-shaped, maroon-crusted lesion measured 0.7 cm in diameter and was located over the fourth knuckle. The patient had chronic obstructive pulmonary disease but was otherwise in good health. He was seronegative for HIV.

For the past few days, a 75-year-old man with a history of chronic obstructive pulmonary disease had suffered from dyspnea and fever (temperature, 38.3°C [101°F]). He also complained of producing excessive foul-smelling sputum but denied any hemoptysis.

A 68-year-old woman was admitted to the hospital with rapidly increasing, painful swelling of the left eye. She had moderately severe, corticosteroid-dependent chronic obstructive pulmonary disease.

Following two witnessed tonic-clonic seizures, a 65-year-old woman with a history of chronic obstructive pulmonary disease was admitted to the hospital. Results of laboratory studies included serum creatinine level, 2 mg/dL; blood urea nitrogen level, 28 mg/dL; and erythrocyte sedimentation rate, 61 mm/h. The patient's antinuclear antibody (ANA) titer was 1:40 with a speckled pattern, and creatinine clearance was 17 mL/min. An ultrasonogram revealed bilateral small kidneys. CT and MRI of the head revealed no abnormalities.

Aortitis

An obese 61-year-old man who had chronic obstructive pulmonary disease and sleep apnea heard a “pop” in his stomach while lifting a heavy weight; severe abdominal pain followed. He was short of breath the next morning, and his physician empirically prescribed cephalexin.

A 70-year-old man was brought from a nursing home to the emergency department with abdominal distention and vomiting of recent onset and a 2-day history of fever and abdominal pain. The patient had chronic obstructive pulmonary disease, type 2 diabetes mellitus, and hypertension. His gastric feeding tube, which had been placed via percutaneous endoscopic gastrostomy, was blocked.

Tai Chi (also known as T'ai Chi Chuan, Taijiquan) is a form of mind-body exercise that has its roots in ancient Chinese martial arts. Throughout Asia, it is often practiced for preventive health, especially among the elderly. In recent years, Tai Chi has become popular in the West among all age groups and has been studied as a therapy for various medical conditions.

A 67-year-old woman was referred for evaluation of exertional dyspnea, with multiple episodes of fever, cough, and pneumonia. She had a long history of cough with sputum and had been admitted several times for exacerbations of chronic obstructive pulmonary disease and pneumonia. She received maintenance therapy with an ipratropium and albuterol combination, fluticasone, and salmeterol, but she continued to experience exertional dyspnea, with an average of 5 or 6 exacerbations and 2 hospital admissions a year.

Abstract: The standard therapies for acute exacerbations of chronic obstructive pulmonary disease include short-acting bronchodilators, supplemental oxygen, and systemic corticosteroids. For most patients, an oxygen saturation goal of 90% or greater is appropriate. Bilevel positive airway pressure (BiPAP) is usually beneficial in patients with progressive respiratory acidosis, impending respiratory failure, or markedly increased work of breathing. However, BiPAP should not be used in patients with respiratory failure associated with severe pneumonia, acute respiratory distress syndrome, or sepsis. Systemic corticosteroids are appropriate for moderate to severe acute exacerbations; many experts recommend relatively low doses of prednisone (30 to 40 mg) for 7 to 14 days. Antibiotic therapy is controversial, but evidence supports the use of antibiotics in patients who have at least 2 of the following symptoms: increased dyspnea, increased sputum production, and sputum purulence.

Abstract: Although smoking cessation is still the most impor- tant intervention in chronic obstructive pulmonary disease (COPD), a variety of pharmacologic therapies are available to help manage symptoms. Short-acting ß2-agonists and/or ipratropium should be taken as needed, and the use of additional therapies is based on the severity of disease. Patients with moderate or severe COPD should regularly take 1 or more long-acting bronchodilators. The long-acting ß2-agonists salmeterol and formoterol have been demonstrated to improve health-related quality of life. Newer therapies include the long-acting anticholinergic tiotropium and a salmeterol-fluticasone combination. These agents improve forced expiratory volume in 1 second and may reduce the rate of acute exacerbations. For patients with moderate to very severe COPD, participation in a pulmonary rehabilitation program can improve health status, quality of life, and exercise tolerance.

Cardiovascular disease is a leading cause of death in patients with chronic obstructive pulmonary disease (COPD). While some physicians may be reluctant to prescribe ß-blockers for these patients, because of concern about adverse effects on lung function, a study conducted by Au and associates indicates that ß-blockers may have an edge over other antihypertensive agents in reducing mortality risk.
