Low back pain is uncommon in children. The case of a 5-year-old boy presenting with back pain that proved to be caused by a metastatic primitive neuroectodermal tumor is presented and the evaluation of such patients is discussed.

The purpose of this study was to evaluate the role of radiography in the assessment/treatment of toxic ingestions and to compare the radiopacity of extended-release formulations to their basic preparations using standard and digitized radiography in vitro. Medications were placed in an in vitro model of the human abdomen. Images were exposed at 80 kV, 20 MAS, with a tube to table distance of 101.6 cm. ⋯ Digital enhancement of a standard radiograph was shown to improve the detectability of the tested oral dosage forms in vitro. Sensitivity of digital radiography in vivo has not yet been established. Based on the data presented, however, further studies using digital radiography to document and to monitor acute toxic ingestions in-vivo are warranted.

Case Reports
Subarachnoid hemorrhage: atypical presentation associated with rapidly changing cardiac arrhythmias.
Subarachnoid hemorrhage (SAH) typically presents with sudden onset of severe headache and is often associated with cardiac arrhythmias. The case of a patient with SAH in whom typical presenting signs and symptoms were absent is presented. This case was characterized by rapidly changing arrhythmias observed in the prehospital setting. The diversity and rapid evolution of arrhythmias can be attributed to the autonomic and electrolyte imbalances that often accompany SAH.

Psychiatric emergencies in the elderly form a small percent of all elderly patients treated in emergency departments. However, accurately diagnosing and understanding behavioral emergencies in the elderly is difficult. ⋯ Causes of these syndromes in the elderly include delirium, dementia, medication side effects, physical illnesses, depression, and alcohol intoxication/dependency. Emergency physicians should consider each of these diagnostic possibilities when evaluating elderly behavioral emergencies to properly diagnose and treat elderly patients.

A retrospective review of cases consulted by the San Francisco Bay Area Regional Poison Control Center during a 2-year period was performed to determine the causes and consequences of seizures associated with poisoning and drug intoxication. Of 233 charts coded as involving seizures, 191 occurred in humans and were available for analysis. The leading causes of seizures reported to the Poison Control Center were cyclic antidepressants (55 cases, 29%); cocaine and other stimulants (55 cases, 29%); diphenhydramine and other antihistamines (14 cases, 7%); theophylline (10 cases, 5%); and isoniazid (10 cases, 5%). ⋯ Seizures in elderly patients were more likely to result in complications and death. The frequency of seizure-related cases by substance type was also compared with the results of an earlier survey performed in 1981, and found a striking increase in the proportion of seizures caused by cocaine and (23% in 1988 to 1989 compared with 4% in 1981). Poison Control Center data can provide valuable information about the causes and consequences of drug-related medical complications, as well as highlight changing trends in drug-related injury.
