Congestive heart failure and cirrhosis are the most common causes of transudative pleural effusions, while pneumonia and malignancy are responsible for the majority of exudative effusions. Plain chest films are valuable in confirming the presence of an effusion, providing clues to the cause, and directing the method of pleural fluid sampling. Thoracentesis is safe and simple, and it is diagnostic in about 75% of cases. Pleural biopsy is indicated for unexplained exudative effusions, most of which are found to result from malignancy or tuberculosis. Medical thoracoscopy, if available, is the procedure of choice for patients with these effusions. Thoracoscopy permits visually directed pleural biopsies and allows for therapeutic intervention at the time of diagnosis, obviating the need for subsequent invasive procedures.

A 57-year-old man requests an extensive medical evaluation as part of a transition in the ownership of his business. He is generally healthy, although he reports that his capacity for physical exertion has diminished over the past several years. He denies chest pain with effort, dyspnea at night or on exertion, cough, and sputum production.

abstract: Hemoptysis has many causes, including bronchiectasis, lung cancer, and bronchitis. The initial goals of the history and physical examination are to differentiate hemoptysis from epistaxis and hematemesis and then to establish its severity. A variety of signs and symptoms may suggest the underlying cause. For example, hematuria suggests vasculitis or an immunologically mediated disease, such as Wegener granulomatosis or systemic lupus erythematosus. The workup includes chest radiography and measurement of hemoglobin and hematocrit levels, platelet count, international normalized ratio, activated partial thromboplastin time, and creatinine level. Chest CT scanning often identifies sources of bleeding that are not apparent on radiographs and sometimes can be used in conjunction with bronchoscopy. Patients with massive hemoptysis should be hospitalized for rapid evaluation and intervention; treatment may include interventional bronchoscopy, angiography, or embolization.

A 57-year-old woman presents with swelling of the hands that began several weeks earlier and is now worsening. She denies joint pain, and she has no history of trauma or significant vascular disease.

Historically, tuberculosis (TB) was the most commoncause of hemoptysis. Classic operas, such asLa Traviata and La Bohème, featured dramatic scenes ofhemoptysis, often with the heroine dying following episodesof deep passion and coughing.

Q:Which patients with chronic respiratory disorders are good candidatesfor pulmonary rehabilitation? When is it a better option than surgery?

A 22-year-old man presents to theemergency department with a2-week history of a worsening nonproductive,irritating dry cough andexertional dyspnea. The patient hasbeen otherwise healthy. He deniesfever, rigors, night sweats, hemoptysis,chest pain, palpitations, orthopnea,paroxysmal nocturnal dyspnea,ankle edema, and lymphadenopathy.

Approximately 90% of cases of lung cancer are attributable to smoking-either directly or as a result of passive exposure. Fifty percent of smokersdie of a smoking-related disease. The 4 most common causes of death-heartattack, lung cancer, chronic obstructive pulmonary disease, and stroke-areall associated with smoking. More lung cancer is diagnosed in former than incurrent smokers.1 The risk of lung cancer decreases each year following smokingcessation, but former heavy smokers will always have a higher risk thannonsmokers.

Abstract: Because of recent advances, more patients may potentially benefit from a variety of interventional bronchoscopic techniques. Nd:YAG laser phototherapy is the most widely used modality and is the treatment of choice for patients with endobronchial malignancies who have large-central airway obstruction. Cryotherapy may be superior to Nd:YAG phototherapy for more distal airways lesions because of the lower risk of airway perforation, but it may be suboptimal for bulky airways disease that requires quick relief of obstruction. Brachytherapy relieves symptoms, such as cough, dyspnea, and hemoptysis, in many patients who have locally invasive airway malignancies. Endobronchial ultrasonography appears to be a safe and sensitive method for staging lung cancer. In select patients with emphysema, a 1-way endobronchial valve can be used to reduce lung volumes. Bronchial thermoplasty is being studied as a potential treatment for asthma. (J Respir Dis. 2006;27(10):415-428)
