Stroke is rare in children but leads to significant morbidity and mortality. Emergency department physicians are likely to be the first to evaluate children suffering strokes and it is, therefore, important for them to recognize common presenting features and risk factors for pediatric stroke. This review describes the epidemiology, clinical presentations, stroke types, associated risk factors, evaluation, treatment, and prognosis of pediatric stroke. Further research is needed on the acute and preventative treatments of pediatric stroke because merely applying our knowledge of stroke in adults to children is insufficient.

Mental health problems in adolescents have been recognized as a significant medical concern. They have been associated with risk-taking behaviors during adolescence. To determine the prevalence of elevated scores for psychological distress among adolescent girls aged 15 to 21 years who present to a pediatric emergency department (PED) for general medical care and to correlate psychological distress scores with sexual and substance use behaviors. The study was performed in the PED of an urban general hospital. We enrolled female patients aged 15 to 21 years cared for in the PED. Subjects completed the Center for Epidemiological Studies-Depression Scale 8 (CES-D8); elevated scores were defined as 7 or greater. The survey collected data on demographics, sexual practices, alcohol and drug use, and health care access and utilization. Two hundred ninety-nine subjects participated. One hundred forty-one participants (47.7%) had CES-D8 scores of 7 or greater. In multivariate logistic regression, factors associated with increased emotional distress were being white, Hispanic, or of other race; having a recent new sex partner; and recent sex without birth control. Alcohol use in the past 3 months was associated with elevated distress as was having a distant relationship with one's parents/guardians. Those who had never had sex or who had sex in the past but not within the past 3 months were also more likely to have elevated CES-D8 scores compared with those who had sex more recently with the use of birth control. Screening for mental health issues in the emergency department may identify a significant number of adolescent patients in need of further evaluation, especially as half of surveyed patients reported the PED as a usual source of health care.

Soft tissue infections frequently prompt visits to the pediatric emergency department. The incidence of these infections has increased markedly in recent years. The emergence of community-acquired methicillin-resistant Staphylococcus aureus is associated with an increasing morbidity, mortality, and frequency of abscess formation. Bedside ultrasound may have a significant impact in the management of patients that present to the pediatric emergency department with soft tissue infections, including cellulitis, cutaneous abscess, peritonsillar abscess, and necrotizing fasciitis. Ultrasound is an efficient, noninvasive diagnostic tool which can augment the physician's clinical examination. Ultrasound has been shown to be superior to clinical judgment alone in determining the presence or the absence of occult abscess formation, ensuring appropriate management and limiting unnecessary invasive procedures.

Bedside ultrasound (BUS) can provide critical information in a rapid and noninvasive manner to the emergency physician. It is widely used in emergency departments (ED) throughout the nation. Literature shows that BUS shortens patient stay and increases patient satisfaction. General emergency medicine (EM) residencies incorporate BUS training in their curricula. However, there are limited data about the training that pediatric emergency medicine (PEM) fellows receive. To determine the extent of training and use of BUS in PEM fellowship programs. A 29-question survey was mailed to all (57) PEM fellowship program directors in the spring of 2006. The response rate was 81% (46/57). Fifty-seven percent (26/46) of the responding PEM fellowship program directors reported that their faculty used BUS in their departments. At 50% (23/46) of programs, fellows perform BUS studies. Sixty-five percent (30/46) of PEM fellowships reported that their fellows receive some BUS training, but only 15 of these programs included BUS training in the curriculum as a 2- to 4-week ultrasound rotation.Sixty-five percent (30/46) of PEM fellowship programs had access to an ultrasound machine, but only 28% (13/46) of programs had their own machine. The main reason not to own an ultrasound machine was a lack of ultrasound expertise in their department (67%, 22/33). Bedside ultrasound training was provided by general EM physicians in 57% (17/30) of programs. Eighty-seven percent of the directors agree that BUS training would benefit their practice.The 2 factors significantly associated with the likelihood of having formal BUS training were access to an ultrasound machine (87% vs 55% P=0.04) and presence of an adult ED with an EM residency at the program (80% vs 42% P=0.03). Pediatric emergency medicine fellowship programs at children's hospitals were significantly less likely to have formal training (33.3% vs 74.2%; P=0.01). Despite literature supporting the benefits of BUS in the ED, many PEM fellowship programs do not incorporate BUS training for their PEM fellows. Most PEM fellows who receive training in BUS are instructed by physicians trained in EM, not PEM.

Examining the young child who presents to the emergency department with a visual or ocular complaint can be a challenge. This article discusses basic concepts of visual and behavioral development and methods for an accurate ocular examination in young children. Topics reviewed include conjunctivitis, orbital and periorbital cellulitis, lacrimal system infections, congenital issues, misalignment, and oncology.

Restraint of children and adolescents with psychiatric problems has generated controversy. Restraint may be defined as methods used to restrict movement or normal access to one's body. Published data to guide restraint practice are limited. To examine frequency of restraint use and patient demographics and chief complaints associated with restraint use in our pediatric emergency department. We retrospectively reviewed the pediatric emergency department records of children (age <18 years) who underwent emergency psychiatric evaluation in an urban general hospital from January 2001 to December 2002. Factors associated with restraint use were determined using multivariate logistic regression. Data were available for 1125 (82%) of 1371 patients who underwent emergency psychiatric evaluation; 76 (6.8%) of 1125 patients were restrained: 37 physical, 19 with medication, and 20 both. Study patients were mean age 13.1 years, 50% girls, 54% blacks, 19% Latinos, and 18% whites; 80% had public insurance. Boys were restrained more often than girls (8.7% vs. 5.2%, P = 0.02). Age, insurance, and race were not associated with restraint use. Patients admitted for inpatient psychiatric care were restrained more frequently than those discharged home (9.9% vs. 3.9%, P < 0.001). In multivariate logistic regression, sex was not associated with restraint use. Restraint use was associated with chief complaints of visual hallucinations (odds ratio, 5.29), out-of-control behavior (odds ratio, 4.65), hyperactivity (odds ratio, 2.26), and admission to a psychiatric facility (odds ratio, 2.40). Approximately 1 in 15 children undergoing psychiatric evaluation were restrained. This is the first study to elucidate correlates of restraint practice in the pediatric emergency department. Further studies examining indications for restraint and comparing methods of restraint are needed.

To identify current practice and staff education regarding the use of restraint in emergency departments for children undergoing psychiatric evaluations and to compare restraint practice and education in emergency medicine residencies (EMRs) and pediatric emergency medicine fellowships (PEMFs). A self-administered survey regarding staff and resident education and the use of restraint for emergency pediatric patients undergoing psychiatric evaluation was mailed to the directors of EMRs and PEMFs. Main outcome measures included frequency of restraint use, staff trained in restraint use, favored positions for physical restraint, and agents regularly used for chemical restraint. Forty-one percent (48/118) of EMRs and 66% (33/50) of PEMFs completed the survey. The great majority of both EMRs and PEMFs report use of physical and chemical restraint in 5% or less of pediatric psychiatric patients. Forty of 47 EMRs and 29 of 32 PEMFs have formal policies on physical restraint use. Far fewer programs have formal policies for chemical restraint (13/33 EMRs and 5/28 PEMFs). A large percentage of both EMRs and PEMFs do not teach their trainees about the application of restraints (EMR = 52%, PEMF = 82%) or the appropriate situations in which to use restraint (EMR = 35%, PEMF = 64%). However, EMRs were more likely than PEMFs to teach about both appropriate restraint application and appropriate situations for their use (RR = 2.6, 1.2-5.8 and RR = 1.8, 1.1-2.9, respectively). The supine position was the position favored by both groups for physical restraint. Therapeutic holding was infrequently used, mostly for younger children. Seventy-two percent of EMRs and 85% of PEMFs used chemical restraint in children. Benzodiazepines and butyrophenones were the most commonly used agents. However, butyrophenones were often misclassified as phenothiazines by both EMRs and PEMFs. Restraint, both physical and chemical, is a widely, but uncommonly used, intervention for pediatric psychiatric patients in emergency departments. Many EMRs and PEMFs do not teach residents about restraint.

Previous studies have shown that the application of the Ottawa knee rule (OKR) reduces the need for radiographs in adults with acute knee injuries. Our objectives were to describe the epidemiology and incidence of knee injuries in children with acute knee trauma and to validate the OKR in a pediatric population. A prospective, consecutive study. Two urban pediatric emergency departments. All children 18 years of age and under who presented with acute traumatic knee injury of less than 1 week's duration, excluding patients with a normal knee examination, superficial skin injuries, prior history of knee injury, underlying bone disease, serious injuries involving two or more organ systems, or altered mental status were enrolled. Physicians assessed each patient for 22 standardized clinical findings prior to radiography. The OKR was applied to each patient by the investigating physician. All 234 patients eligible for the study had radiographs of the affected knee. The median age was 13 years with a range of 2 to 18 years. Using the OKR criteria for obtaining knee radiographs, 12 of 13 patients with fractures were identified (sensitivity 92%; 95% CI= 64-99). The missed case was an 8-year-old male who had sustained a nondisplaced fracture of the proximal tibia after a fall. If the OKR were applied to the pediatric population, it would have reduced the need for radiography in 46% of children. In the pediatric population studied, the OKR did not identify all patients with knee fractures. Future studies may consider modifying the OKR to accommodate the differences between pediatric and adult patients to improve the sensitivity of the rule while maintaining its specificity, before it can be applied routinely in clinical practice.

Physicians providing emergency department care to children primarily use nebulizers for the delivery of bronchodilators and these physicians have misconceptions regarding the advantages and disadvantages of using metered-dose inhalers (MDIs) with a spacer (MDI + S) for acute asthma exacerbations. Self-administered mail survey. Emergency department. Emergency medicine section members of the American Academy of Pediatrics and Canadian Pediatric Society. Bronchodilator delivery methods in acute pediatric asthma. The 2 principal outcomes for bivariate analysis were self-reported nebulizer use in all patients and MDI + S use in patients with mild acute asthma. Of eligible physicians, 333 (51%) of 567 responded. The majority were dual trained in pediatrics and pediatric emergency medicine (72%) and practiced full time (83%) in an urban (83%) pediatric emergency department (80%). The most commonly cited advantages of MDIs were their cost (33%) and speed of use (28%). The most commonly cited disadvantages were patient or parent dissatisfaction (24%) and relative ease of nebulizer use (23%). Only 10% to 21% of participants used MDIs in the emergency department and reserved this delivery method for children with mild asthma exacerbations. There were no significant associations between selected respondent demographic variables and the use of MDIs. Misconceptions regarding the efficacy and safety of MDI + S for the treatment of acute asthma exacerbations exist but are limited to a minority of surveyed emergency medicine physicians caring for children. Nebulizers remain the preferred method of routine bronchodilator delivery by physicians providing care to pediatric asthmatics in the emergency department.
