Acute lupus pneumonitis was the presenting manifestation of systemic lupus erythematosus in six of 12 cases in this series. The clinical picture was characterized by severe dyspnea, tachypnea, fever and arterial hypoxemia. Radiographic findings included an acinar filling pattern which was invariably found in the lower lobes and was bilateral in 10 of the(More)
Lung cancer is the leading cause of cancer death in the United States and around the world. A vast majority of lung cancer deaths are attributable to cigarette smoking, and curbing the rates of cigarette smoking is imperative. Understanding the epidemiology and causal factors of lung cancer can provide additional foundation for disease prevention. This(More)
Lung cancer is the most common malignancy in the elderly population and was responsible for greater than 125,000 deaths in 1985. Although advances have been made in the areas of diagnosis and staging, the long-term outlook for the disease remains poor, primarily because of dissemination of disease prior to diagnosis. Despite this, several studies suggest(More)
Nonchemotherapeutic drugs may also cause pulmonary parenchymal alterations. Mechanisms of pulmonary damage by these agents are diverse and may involve alterations of pulmonary homeostasis. Clinical features of noncytotoxic, drug-induced pulmonary disease are more heterogeneous than those associated with cytotoxic drugs, and several clinical syndromes are(More)
Lung cancer is the leading cause of cancer deaths in the United States. The individual therapeutic approach and prognosis depends on accurate diagnosis and staging. Flexible bronchoscopy (FB) and transthoracic needle biopsy (TNB) are the most widely used techniques for this purpose. This article provides a critical overview of indications, diagnostic yield,(More)
Flexible fiberoptic bronchoscopy is the most useful invasive technique for diagnosing lung cancer. This article details the use and efficacy of bronchoscopy with such established techniques as forceps biopsy, brush biopsy, and bronchial washing in the diagnosis and staging of bronchoscopically visible central lung cancer and peripheral lung cancer. The(More)
Thoracic metastases from squamous carcinoma and adenocarcinoma of the cervix were studied by reviewing 245 consecutive cases to describe comparative incidence, natural history, and radiographic patterns. The incidence of chest metastases was higher for adenocarcinoma (20%) than for squamous carcinoma (4%). Few patients diagnosed in the early stages of(More)
