The number of reported cases of skeletal muscle relaxant ingestion has been increasing in the United States, although fatalities are rare. A 30-year-old women ingested 300 mg of baclofen and ethanol. She was able to ambulate into the Emergency Department (ED) 50 min later, but within 30 min post-arrival had a Glasgow Coma Score of 3. ⋯ Her neurologic status returned to her previous state. Coma may occur rapidly after baclofen overdose, and the respiratory depression may be exacerbated by the co-ingestion of ethanol. Primary importance in the treatment of such ingestions should be placed on maintenance of an airway and respiratory support.

Serum amylase and lipase levels are commonly obtained in the emergency department for the diagnosis of acute pancreatitis. The role of these enzymes has frequently been the subject of confusion and controversy. This article comprehensively reviews the history, biochemistry, clinical, and laboratory literature on both enzymes as used in the evaluation of pancreatitis. Specific guidelines are presented to assist the Emergency Physician in the appropriate use and interpretation of these clinical laboratory tests.

This was a study to determine if the Ottawa Ankle Rules (OAR) for requesting x-ray studies in twisting ankle and foot injuries are applicable in our Asian population. Four hundred ninety-four consecutive eligible patients presenting to the emergency department with twisting injuries about the ankle were examined by emergency physicians for clinical criteria requiring ankle and foot x-ray studies according to the OAR. ⋯ When the rules were modified to cast a wider screening net, sensitivity improved to 0.99. We conclude that the OAR are not applicable to our population because of inadequate sensitivity, but when modified become acceptable and can reduce the number of x-ray studies requested by 28%.

Quetiapine (Seroquel) is a member of a new class of antipsychotic agents used in the treatment of schizophrenia. Its pharmacologic effect is primarily mediated via antagonistic binding to serotonergic (5HT2) and dopaminergic (D2) receptors. Presented is a case of acute quetiapine overdose in a patient with associated tachycardia, hypotension, prolonged QTc, and rapid progression to coma. ⋯ The patient's mental status rapidly improved within several hours of the ingestion, and the prolonged QTc and tachycardia resolved by the second and third days of hospitalization, respectively, without further intervention. This case illustrates the potential for hemodynamic instability and sudden deterioration in level of consciousness, warranting close monitoring and early intubation for airway protection. All patients with acute quetiapine overdose requiring hospitalization should be admitted to an intensive care unit setting.
