Infections and their sequelae are a major cause of death among patients admitted to the surgical intensive care unit (ICU). Studies of passive immunotherapy with standard intravenous immune globulin and hyperimmune globulin directed against gram-negative core lipopolysaccharide to prevent gram-negative infections and their serious systemic complications have had equivocal results in such patients.

Nosocomial infection is a major risk for premature infants with very low birth weights. One reason for their susceptibility to infection may be antibody deficiency, since there is little transfer of maternal IgG to the fetus before 32 weeks' gestation.
4408. Do the results of randomized clinical trials of cardiovascular drugs influence medical practice? The SAVE Investigators.

Medical practice patterns change in response to a variety of stimuli, one of which may be the publication of the results of randomized clinical trials. We assessed the temporal association between the publication of clinical trials on myocardial infarction and changes in treatment practices for this disorder.
4409. Effect of the antiarrhythmic agent moricizine on survival after myocardial infarction.
The Cardiac Arrhythmia Suppression Trial (CAST) tested the hypothesis that the suppression of asymptomatic or mildly symptomatic ventricular premature depolarizations in survivors of myocardial infarction would decrease the number of deaths from ventricular arrhythmias and improve overall survival. The second CAST study (CAST-II) tested this hypothesis with a comparison of moricizine and placebo.
4410. Calcium supplementation and increases in bone mineral density in children.

Increased dietary intake of calcium during childhood, usually as calcium in milk, is associated with increased bone mass in adulthood; the increase in mass is important in modifying the later risk of fracture. Whether the increase is due to the calcium content of milk, however, is not certain.
4411. High-osmolality and low-osmolality contrast agents.4412. A randomized trial of a program to reduce the use of psychoactive drugs in nursing homes.

Although psychoactive medications have substantial side effects in the elderly, these drugs are used frequently in nursing homes. Few interventions have succeeded in changing this situation, and little is known about the clinical effects of such interventions.
4413. Lack of efficacy of phenytoin in recessive dystrophic epidermolysis bullosa. Epidermolysis Bullosa Study Group.
Recessive dystrophic epidermolysis bullosa is an uncommon, severely disabling, heritable disorder characterized by abnormal fragility of the skin. Open trials have suggested that phenytoin is an effective treatment, and this therapy is now widely used.
4414. Reactivation of unstable angina after the discontinuation of heparin.
Heparin is an effective, widely used treatment for unstable angina. Among patients enrolled in a double-blind, randomized, placebo-controlled trial comparing intravenous heparin, aspirin, both treatments, and neither during the acute phase of unstable angina, we encountered patients in whom unstable angina was reactivated after heparin was discontinued.
4415. The effect of high doses of calcium-channel blockers on survival in primary pulmonary hypertension.
Primary pulmonary hypertension is a progressive, fatal disease of unknown cause. Vasodilator drugs have been used as a treatment, but their efficacy is uncertain.
4416. Diagnosis and staging of colonic tumors by conventional abdominal sonography as compared with hydrocolonic sonography.
Ultrasonic examination has become increasingly important in the diagnosis of diseases of the gastrointestinal tract. In neoplastic diseases of the large intestine, however, the diagnostic value of conventional transabdominal sonography is limited. The purpose of this investigation was to determine whether the evaluation and staging of colonic tumors would be improved by the retrograde instillation of water into the colon in a procedure called hydrocolonic sonography.
4417. The use of digoxin-specific Fab fragments for severe digitalis intoxication in children.
Because life-threatening digitalis intoxication is unusual in children, treatment with digoxin-specific-antibody Fab fragments (Fab) has rarely been reported. We describe the efficacy of Fab in the treatment of children with severe digitalis intoxication.
4418. Localization of pancreatic endocrine tumors by endoscopic ultrasonography.

After a pancreatic endocrine tumor has been diagnosed on the basis of clinical signs and the results of laboratory tests, localization of the tumor by the usual imaging procedures fails in as many as 40 to 60 percent of patients. Endoscopic ultrasonography, a sensitive test for small carcinomas of the pancreas, might also be useful in patients with endocrine tumors of the pancreas that cannot be localized by conventional methods.
4420. The risk of stroke in patients with acute myocardial infarction after thrombolytic and antithrombotic treatment. Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico II (GISSI-2), and The International Study Group.
作者: A P Maggioni.;M G Franzosi.;E Santoro.;H White.;F Van de Werf.;G Tognoni.
来源: N Engl J Med. 1992年327卷1期1-6页
Many trials in patients with acute myocardial infarction have demonstrated that thrombolytic therapy is not associated with an excessive risk of stroke, as compared with conventional treatment. However, the incidence of various forms of stroke in patients treated with different thrombolytic and antithrombotic regimens and the associated effect of risk factors for stroke are largely unknown.
