To evaluate the nature of the decision to write a do-not-resuscitate (DNR) order in the Emergency Department (ED). ⋯ Because there remains considerable reluctance on the part of physicians to discuss the DNR issue before patients become critically ill, it is often necessary for ED physicians to write a DNR order. Although the ED is not an ideal setting for discussion of DNR orders and patients and families do not generally initiate this discussion, DNR orders can be written by ED physicians after consultation with the family.

Elderly patients have a disproportionate incidence of nosocomial pneumonia (NP) and a higher mortality rate, yet few studies have focused on this high-risk population. We undertook a study to examine risk factors for NP in elderly inpatients and to describe how these patients differ from younger patients with NP. ⋯ We conclude that the specific risk factors of poor nutrition, neuromuscular disease, and tracheal intubation may prove useful to target future clinical interventions to prevent NP in the elderly.

In summary, Wrenn and Brody's [14] study raises important questions about the appropriate role of emergency physicians in discussing DNR decisions in the emergency setting. Their approach to DNR orders expands, appropriately we believe, the traditional role of emergency physicians. ⋯ In addition, emergency physicians have a heightened obligation to promptly address DNR status when appropriate decisions about resuscitation have been reached previously, as in the following cases: (1) when a clearly valid portable prehospital DNR order is in effect; (2) when the patient's primary physician clearly indicates to the emergency physician that the patient is DNR; (3) when an incompetent patient has an advance directive that explicitly precludes CPR and unquestionably applies to the current situation; (4) when a clearly competent, informed patient requests that a DNR order be entered. Finally, we advise emergency physicians against using the principle of futility as sole justification for DNR orders except in situations in which cardiopulmonary arrest is expected, and outcome data suggest that survival is virtually unprecedented.

The syndrome of inappropriate thyroid-stimulating hormone (TSH) secretion, characterized by elevated serum free thyroxine and triiodothyronine levels in association with measurable serum TSH concentrations, remains an uncommon cause of hyperthyroidism that is being recognized with increasing frequency. The hyperthyroidism may be due to either neoplastic pituitary TSH secretion or selective pituitary resistance to thyroid hormone. In an effort to better understand this rare cause of hyperthyroidism, we undertook a retrospective analysis of our institution's experience with this condition. ⋯ Adequate treatment exists for the two primary causes of TSH hypersecretion. TSH-secreting pituitary adenomas are treated with surgery and, if necessary, adjuvant pituitary radiotherapy. The results are generally good if the tumor is diagnosed and treated at an early stage. Primary therapy for hyperthyroidism due to selective pituitary resistance to thyroid hormone is aimed at suppression of pituitary TSH hypersecretion. The evaluation of any patient with hyperthyroidism must be thorough and, in some cases, should include measurement of TSH to determine the presence of inappropriate secretion. Eliminating this diagnosis will help avoid improper and potentially harmful treatment of hyperthyroid patients.
