Small cell lung cancer accounts for approximately 15% of bronchogenic carcinomas. It is the cancer most commonly associated with various paraneoplastic syndromes, including the syndrome of inappropriate antidiuretic hormone secretion, paraneoplastic cerebellar degeneration, and Lambert-Eaton myasthenic syndrome. Because of the high propensity of small cell lung cancer to metastasize early, surgery has a limited role as primary therapy. ⋯ In Japan and some other Asian countries, the combination of irinotecan and cisplatin is the standard chemotherapeutic regimen. Clinical trials using thalidomide, gefitinib, imatinib, temsirolimus, and farnesyltransferase inhibitors have not shown clinical benefit. Other novel agents such as bevacizumab have shown promising early results and are being evaluated in larger trials.

Comparative StudyOutcomes of patients with stable heart failure undergoing elective noncardiac surgery.
To evaluate modern surgical outcomes in patients with stable heart failure undergoing elective major noncardiac surgery and to compare the experience of patients with heart failure who have reduced vs preserved left ventricular ejection fraction (EF). ⋯ Patients with clinically stable heart failure did not have high perioperative mortality rates in association with elective major noncardiac surgery, but they were more likely than patients without heart failure to have longer hospital stays, were more likely to require hospital readmission, and had a substantial long-term mortality rate.

ReviewMedical informed consent: general considerations for physicians.
Medical informed consent is essential to the physician's ability to diagnose and treat patients as well as the patient's right to accept or reject clinical evaluation, treatment, or both. Medical informed consent should be an exchange of ideas that buttresses the patient-physician relationship. The consent process should be the foundation of the fiduciary relationship between a patient and a physician. ⋯ When physicians and patients take medical informed consent seriously, the patient-physician relationship becomes a true partnership with shared decision-making authority and responsibility for outcomes. Physicians need to understand informed medical consent from an ethical foundation, as codified by statutory law in many states, and from a generalized common-law perspective requiring medical practice consistent with the standard of care. It is fundamental to the patient-physician relationship that each partner understands and accepts the degree of autonomy the patient desires in the decision-making process.

Coccidioidomycosis is a common infectious disease in the southwestern United States. Although Coccidioides species are not endemic in other areas of the country, the rapid population growth in the southwestern United States in recent decades and the increase in tourism mean that many people travel to the Southwest and return home before developing the clinical syndrome of coccidioidomycosis. In this respect, coccidioidomycosis is a disease of national importance. ⋯ The diagnosis is often made on the basis of serologic findings. Treatment is usually with an azole or amphotericin B, depending on the clinical manifestations and the immune status of the host. We discuss the most common clinical manifestations, the best way to make the diagnosis, and the treatment of common infections.

Comparative StudyInappropriate use of symptom-triggered therapy for alcohol withdrawal in the general hospital.
To determine if hospitalized medical and surgical patients were placed inappropriately on symptom-triggered therapy (STT) for alcohol withdrawal syndrome (AWS) and if certain conditions were more likely to be associated with inappropriate STT use or adverse events. ⋯ Fewer than half of the randomly selected patients met both of the inclusion criteria for the CIWA-Ar instrument, leading us to conclude that more stringent evaluation is needed. Particularly postoperatively, alternative explanations for putative AWS should be sought. Health care professionals should more aggressively seek information on recent alcohol use from medical records, family members, and patients themselves.
