The neuroleptic malignant syndrome (NMS), clinically manifested by hyperpyrexia, mental status changes, muscular rigidity, and autonomic dysfunction, is an idiosyncratic reaction to major neuroleptic pharmacologic agents. The reported causes of morbidity and mortality include respiratory insufficiency, cardiovascular collapse, arrhythmias, and renal failure. Coagulopathy does not seem to be a prominent component of the syndrome. We observed a case of NMS in which disseminated intravascular coagulation was a prominent feature.

Comparative Study Clinical Trial Controlled Clinical Trial
A double-blind clinical trial in weight control. Use of fenfluramine and phentermine alone and in combination.
We performed a double-blind, controlled clinical trial comparing phentermine resin (30 mg in the morning), fenfluramine hydrochloride (20 mg three times a day), and a combination of phentermine resin (15 mg in the morning) and fenfluramine hydrochloride (30 mg before the evening meal), and placebo. We combined low doses of the two drugs to maintain efficacy while diminishing adverse effects. Eighty-one people with simple obesity (130% to 180% of ideal body weight) participated. ⋯ Adverse effects were less frequent with the combination regimen than with other active treatments. Thirty-seven participants dropped out of the study, 18 for reasons related to drug treatment. Combining fenfluramine and phentermine capitalized on their pharmacodynamic differences, resulting in equivalent weight loss, fewer adverse effects, and better appetite control.

We retrospectively studied 11 instances of patients requiring prolonged mechanical ventilation. Their spontaneous ventilatory measurements were not useful in judging their ability to wean, since these measurements did not change from the period of unsuccessful weaning to the period of progressive weaning from the ventilator. ⋯ We also found that the course and the duration of the entire weaning process could be predicted once progressive weaning had begun. We conclude that the adverse factor score and ventilator score correlate with the ability of patients receiving prolonged mechanical ventilation to wean.

Emphysematous cholecystitis developed in a 65-year-old man 24 hours following resuscitation from cardiac arrest. Our findings in this case support the importance of ischemia in this disease process.

Following the collapse of a building, seven subjects (aged 18 to 41 years) were released from under the rubble within one to 28 hours. All seven suffered from extensive crush injuries with evidence of severe rhabdomyolysis and were treated by the induction of an alkaline solute diuresis immediately on their extrication from the debris. ⋯ In the past, injuries of similar severity have been associated with a high incidence of acute renal failure and a high mortality rate, yet none of our patients had azotemia or renal failure. We attribute this success to the unprecedented early institution of appropriate therapy.
