Respiratory bronchiolitis-associated interstitial lung disease and its relationship to desquamative interstitial pneumonia.
Respiratory bronchiolitis is a mild inflammatory reaction commonly noted in asymptomatic cigarette smokers. We reviewed 18 cases of respiratory bronchiolitis-associated interstitial lung disease (RB/ILD), which had been diagnosed on the basis of clinical evaluation and open-lung biopsy. All patients were cigarette smokers. ⋯ In most patients, respiratory improvement ensued when they stopped smoking. Because of histologic similarities to desquamative interstitial pneumonia (DIP), the 18 cases of RB/ILD were compared with 36 cases of DIP. DIP tended to occur in older persons, caused more severe symptoms, displayed ground glass infiltrates on chest roentgenograms, was characterized by more severe interstitial disease on pulmonary function tests, and was often associated with progressive respiratory disease.

ReviewPreoperative assessment of cardiac patients undergoing noncardiac surgical procedures.
A careful clinical history and physical examination are the most important components of the preoperative assessment of the cardiac patient who is to undergo a noncardiac surgical procedure. From these factors and the nature of the surgical procedure planned, a reasonable estimate of potential cardiac risk can be formulated to guide judicious preoperative testing for further definition of potentially high-risk patients. The potential risks associated with an invasive cardiac procedure or surgical intervention must always be considered along with the potential benefits of such a procedure in an attempt to reduce the cardiac risk of noncardiac operations. Aggressive and conscientious preoperative assessment and perioperative care of the high-risk patient by the concerted efforts of the medical consultant, anesthesiologist, and surgeon may substantially diminish cardiac-related morbidity and mortality during noncardiac surgical procedures.

Despite the lack of a definitive remedy for central nervous system demyelination in multiple sclerosis, certain manifestations of the disease are treatable. Recognition and identification of specific impairments, disabilities, and handicaps faced by the patient afford the physician the best opportunity to provide effective intervention. ⋯ The goal of rehabilitation in multiple sclerosis is to maximize the patient's physical, emotional, social, and vocational independence. Through the multidisciplinary efforts of numerous health-care workers in close cooperation with the patient and the family, this goal can be attained.

Neuroepidemiology has been important in providing clues about the cause and pathogenesis of multiple sclerosis. In this review, we update the incidence and prevalence rates of multiple sclerosis in Olmsted County, Minnesota, and examine the potential role of viruses, exposure to animals, toxins, trauma, and diet in the development of this disease. Diseases of probable autoimmune nature have also been linked to multiple sclerosis. These descriptive data may contribute to the formulation of testable specific hypotheses about the pathogenesis and treatment of multiple sclerosis and other demyelinating diseases.

We reviewed the medical records of 70 patients with systemic cancer in whom a subdural hematoma (SDH) developed. Among patients with a solid tumor, trauma and use of anticoagulants were common causes of SDH, and these patients had a relatively favourable outcome. Among patients with a hematologic cancer and in the rest of the patients with a solid tumor, coagulopathies and dural metastatic involvement were the most common causes of SDH. Recurrent SDH and death due to SDH were common in the latter group.
