Subcutaneous emphysema is an unusual complication of bronchiolitis. The investigators describe a patient with bronchiolitis who developed extensive subcutaneous emphysema. ⋯ Review of the literature shows a multitude of causes of subcutaneous emphysema. The vast majority of cases resolve without intervention.

The objective was to determine the association between the performance rates of pediatric advanced life-support procedures, intubation and vascular access, by emergency medicine technician-paramedics (EMT-P), and introduction of an EMT-P pediatric advanced life support (PALS) clinical course. Prehospital EMT-P care records from January 1990 to December 1991 were retrospectively reviewed to determine endotracheal intubation and vascular access performance rates. These rates were compared with intubation and vascular access performance rates by EMT-Ps from January 1983 to June 1985. ⋯ Vascular access, intravenous or intraosseous, was established in 130 (73%) of the children; no attempt was made in 14 children. The vascular access performance rate was 64% for children younger than 18 months of age and 79% for children > or = 18 months old. Intubation performance rates of EMT-Ps before the EMT-P PALS clinical course (January 1983 to June 1985) were 48% for children younger than 18 months of age and 85% for children > or = 18 months old.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
Diagnostic tests for occult bacteremia: temperature response to acetaminophen versus WBC count.
A cohort of 484 febrile children were examined to (1) assess the utility of temperature response to acetaminophen as a diagnostic test for occult bacteremia (OB) and (2) compare it with the white blood cell (WBC) count. For a period of 18 months, the records of all febrile children seen in the emergency department were reviewed. Testing a response to acetaminophen of a < or = 0.8 degrees C decrease in temperature, the sensitivity, specificity, and positive and negative predictive values were 47%, 74%, 12%, and 95%, respectively. ⋯ The difference was not significant (P > 0.05). The conclusion reached was that temperature response to acetaminophen has predictive values that are similar to the WBC count, and it may provide useful information. However, neither test is impressive, and the clinician cannot reliably predict which febrile children are at risk.

The case of a 57-year-old male athlete who developed acute hyponatremia during participation in a 100 mile ultra-marathon is discussed. The initial presentation was one of rapid neurological deterioration and transient cardiovascular instability. ⋯ With increasing interest in ultra-endurance events, the incidence of acute hyponatremia may increase. It is important that emergency physicians recognize this phenomenon and be familiar with the principles of acute intervention.

Comparative Study
ED length-of-stay and illness severity in dizzy and chest-pain patients.
Emergency department (ED) length of stay, illness severity, and patterns of ED-based testing can be used to compare different ED patient populations. To assess the relative significance of ED patients with dizziness and chest pain in emergency medicine practice, the investigators formed a retrospective chart review of 3,864 adults (age > or = 16 years) seen at the University of North Carolina Hospitals' ED during May and June of 1991. Patients were eligible if they had any complaint of dizziness (n = 259), nontraumatic chest pain (n = 168), or both (n = 18). ⋯ Chest-pain patients were more likely to undergo electrocardiogram and x-ray testing, whereas dizzy patients more often received testing such as brain computed tomography scanning (10.8% v 3.6%, P = .01). ED patients with dizziness and chest pain were similar with regard to ED length of stay. Given their overall similarities to the chest-pain group, dizzy patients appear to represent a significant population of ED patients and may warrant more clinical study.
