Practical selection of antiemetics.

An understanding of the pathophysiology of nausea and the mechanisms of antiemetics can help family physicians improve the cost-effectiveness and efficacy of therapy. Nausea and vomiting are mediated primarily by visceral stimulation through dopamine and serotonin, by vestibular and central nervous system causes through histamine and acetylcholine, and by chemoreceptor trigger zone stimulation through dopamine and serotonin. Treatment is directed at these pathways.

Treatment of ethylene glycol poisoning.

Ingestion of ethylene glycol may be an important contributor in patients with metabolic acidosis of unknown cause and subsequent renal failure. Expeditious diagnosis and treatment will limit metabolic toxicity and decrease morbidity and mortality. Ethylene glycol poisoning should be suspected in an intoxicated patient with anion gap acidosis, hypocalcemia, urinary crystals, and nontoxic blood alcohol concentration.

Rhabdomyolysis in a patient receiving the combination of cerivastatin and gemfibrozil.

Straightforward reports of unusual drug experiences are included in this section. While selected references may be cited, the purpose of a Drug Experience report is not to present an extensive review of the literature. A related section, Grand Rounds, includes papers that are well-documented patient case reports with a thorough review of the important literature to help put the case in perspective.

The use of ketorolac in lumbar spine surgery: a cost-benefit analysis.

The use of ketorolac was studied in patients undergoing lumbar laminectomy and those receiving lumbar fusion with or without instrumentation. Laminectomy patients in the ketorolac group used significantly less narcotic analgesic than did those in the narcotic treatment group. Ketorolac patients in both surgical categories experienced better pain control than narcotic group patients did.
