Traumatic and unsuccessful lumbar punctures can cause substantial diagnostic ambiguity that may lead to unnecessary antibiotic use and hospitalization, in addition to patient discomfort. Risk factors for obtaining traumatic and unsuccessful lumbar punctures have been studied in a limited fashion only. We sought to determine patient, physician, and procedural factors associated with traumatic and unsuccessful lumbar punctures in children. ⋯ Of the factors associated with traumatic or unsuccessful lumbar punctures in children, advancement of the spinal needle with the stylet in place and lack of local anesthetic use are the most modifiable. Modification of these procedural factors may reduce the risk of traumatic or unsuccessful lumbar punctures in children.

Comparative Study
Pneumococcal bacteremia in febrile infants presenting to the emergency department before and after the introduction of the heptavalent pneumococcal vaccine.
Fever is among the most common presenting complaints of infants and children younger than 3 years who present to the emergency department (ED). The evaluation and management of the febrile child is evolving rapidly. We compare the proportion of pneumococcal bacteremia between febrile infants and children younger than 3 years who had and had not received the heptavalent pneumococcal vaccine and who had received blood culture tests in our ED. ⋯ Pneumococcal bacteremia was found to be lower in our patients who had received the heptavalent pneumococcal vaccine than in the patients who had not.

Comparative Study
Measuring and forecasting emergency department crowding in real time.
We quantified the potential for monitoring current and near-future emergency department (ED) crowding by using 4 measures: the Emergency Department Work Index (EDWIN), the National Emergency Department Overcrowding Scale (NEDOCS), the Demand Value of the Real-time Emergency Analysis of Demand Indicators (READI), and the Work Score. ⋯ The EDWIN, the NEDOCS, and the Work Score monitor current ED crowding with high discriminatory power, although none of them exceeded the performance of occupancy level across the range of operating points. None of the measures provided substantial advance warning before crowding at low rates of false alarms.

Cyanide poisoning must be seriously considered in victims of smoke inhalation from enclosed space fires; it is also a credible terrorism threat agent. The treatment of cyanide poisoning is empiric because laboratory confirmation can take hours or days. Empiric treatment requires a safe and effective antidote that can be rapidly administered by either out-of-hospital or emergency department personnel. ⋯ The efficacy of sodium thiosulfate is based on individual case studies, and there are contradictory conclusions about efficacy in animal models. The onset of antidotal action of sodium thiosulfate may be too slow for it to be the only cyanide antidote for emergency use. Hydroxocobalamin is being developed for potential introduction in the United States and may represent a new option for emergency personnel in cases of suspected or confirmed cyanide poisoning in the out-of-hospital setting.
