Eritrea became a member of the United Nations in 1993, after a devastating 30-year war of independence with Ethiopia. Although Eritrea suffers from many of the problems beset by the developing world, the people are determined to rebuild their country. Emergency medical care and emergency services are in their infancy, yet the signs of progress are already visible in the capital city of Asmara. This report describes the current state of the prehospital system and emergency medical care in Eritrea.

The objective of this study was to determine common practices for testing for Human Immunodeficiency Virus (HIV), particularly in patients with other sexually transmitted diseases (STD) in emergency departments (ED) with residency training in Emergency Medicine. Via mail, 112 directors of academic emergency medicine programs in the United States were surveyed. ⋯ HIV testing was performed in the ED in 54% of responding institutions under special circumstances such as employee testing after occupational exposures (54%), cases of rape (46%), and suspicion of HIV infection by clinical manifestations other than suspected STD (36%). Based on the results it was determined that academic EDs do not routinely test for HIV in patients suspected of having a STD and have variable testing practices and policies regarding other possible HIV exposures.

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.

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.

Injectable benzodiazepines are commonly stocked on ambulances for use by paramedics. We evaluated the stability of lorazepam and diazepam as a function of storage temperature. Diazepam (5 mg/mL) and lorazepam (2 mg/mL) injectable solutions were stored for up to 210 days in clear glass syringes at three conditions: 4 degrees C to 10 degrees C (refrigerated); 15 degrees C to 30 degrees C (on-ambulance ambient temperature); and 37 degrees C (oven-heated). ⋯ These results suggest that diazepam and lorazepam can be stored on ambulances. When ambient storage temperatures are 30 degrees C or less, ambulances carrying lorazepam and diazepam should be restocked every 30 to 60 days. When drug storage temperatures exceed 30 degrees C, more frequent stocking or refrigeration is required.
