The authors report the case of a 6-year-old boy with a spinal cord arteriovenous malformation (AVM) who presented with acute flank pain and a delayed onset of paraplegia. An early diagnosis of a spinal cord AVM was made difficult by the absence of neurological findings on initial evaluation. Included is a description of his clinical course, and the presentation of spinal AVMs to the emergency physician is discussed.

This study was conducted to determine the utility of metal detection in coin localization by inexperienced operators, and determine the rate of spontaneous passage of asymptomatic esophageal coins. All children who presented to the emergency department of an urban children's hospital with a suspected coin ingestion were eligible. Coin location was predicted from metal detector results, while radiographs confirmed location. ⋯ Six of eight asymptomatic patients with esophageal coins spontaneously passed their coins. These results show that metal detection is a good screening test for coin presence and to determine coin location as esophageal. Spontaneous passage of asymptomatic esophageal coins warrants further study.

The tricyclic antidepressant (TCA) agents are recognized for their potentially lethal cardiovascular and neurological effects in poisoned patients. The 12-lead electrocardiogram (ECG) has emerged as a popular bedside tool in the evaluation of TCA toxicity. Although the history and physical examination play a key role in the assessment of the patient with potential TCA poisoning, the presence or absence of features of the TCA toxidrome are not sufficient to detect or exclude toxicity from this class of drugs. ⋯ The majority of these patients will also display these changes early in their emergency department stay. However, the appearance of these findings, either alone or in combination, does not mean the patient will develop significant cardiac or neurological toxicity. The ECG can neither unequivocally rule in nor rule out impending toxicity; recognizing these limitations, the emergency physician can use this bedside tool in combination with other clinical data during the assessment of the poisoned patient.

A 7-month-old child presented to the emergency department (ED) with 2 hours of painless, nonprojectile emesis and a normal mental status. Over a 3-hour period in the ED, the child remained pain-free, but developed hematemesis, hematochezia, and lethargy, progressing to unresponsiveness. ⋯ The diagnosis was made by an abdominal ultrasound, which demonstrated an ileal-cecal intussusception that ultimately required surgical reduction. This case illustrates an insidious and poorly understood presentation of a common childhood affliction, as well as the utility of abdominal ultrasound in evaluating a hemodynamically stable patient with intussusception.

Case Reports
Painless aortic dissection presenting as hoarseness of voice: cardiovocal syndrome: Ortner's syndrome.
Most of the neurological manifestations of the aortic dissection are due to neuronal ischemia secondary to either extension of the dissection process into a branch artery, or compression of an artery by the false lumen of the dissecting aortic hematoma. However, the enlarging false lumen may directly compress on an adjacent nerve, causing neuronal injury resulting in neurological symptoms. This may particularly take place when a distal intimal tear does not decompress the false lumen, resulting in formation of an expanding blind pouch. ⋯ During surgical exploration, the recurrent laryngeal nerve was found compressed by the false lumen at the level of aortic arch. Aortic root replacement was performed successfully, resulting in complete resolution of the hoarseness. The neurological manifestations of aortic dissection, and the cardiovocal syndrome, are discussed.
