Background and aims Children with first complex febrile seizure (CFS) are often admitted for observation. The goals of this study were 1) to assess the risk of seizure recurrence during admission, 2) to determine whether early EEG affects acute management. Design/methods We retrospectively reviewed a cohort of children 6–60 months of age admitted from a Pediatric Emergency Department for first CFS over a 15 year period. We excluded children admitted for supportive care of their febrile illness. Data extraction included age, gender, seizure features, laboratory and imaging studies, EEG, further seizures during admission, and antiepileptic drugs (AEDs) given. Results One hundred eighty three children met inclusion criteria. Seven patients had seizures during the admission (7/183 or 3.8%) Since 38 children were loaded with anti-epileptic medication during their visit, the adjusted rate is 7/145 or 4.8. Increased risk of seizure recurrence during admission was observed in children presenting with multiple seizures (P = 0.005). EEG was performed in 104/183 children (57%) and led to change in management in one patient (1%, 95% C.I. 0.05–6%). Six of the 7 children with seizure had an EEG. The study was normal in 3 and findings in the other 2 did not suggest/predict further seizures during the admission. Conclusions Children with first CFSs are at low risk for seizure recurrence during admission. Multiple seizures at presentation are associated with risk of early recurrence and may warrant an admission. EEG had limited effect on acute management and should not be an indication for admission.

Objectives We sought to identify predictors for a drainable suppurative adenitis [DSA] among patients presenting with acute cervical lymphadenitis. Methods A retrospective cross sectional study of all patients admitted to an urban pediatric tertiary care emergency department over a 15 year period. Otherwise healthy patients who underwent imaging for an evaluation of cervical lymphadenitis were included. Cases were identified using a text-search module followed by manual review. We excluded immunocompromised patients and those with lymphadenopathy felt to be not directly infected (i.e. reactive) or that was not acute (symptom duration >28 days). Data collected included: age, gender, duration of symptoms, highest recorded temperature, physical exam findings, laboratory and imaging results, and surgical findings. A DSA was defined as >1.5 cm in diameter on imaging. We performed binary logistic regression to determine independent clinical predictors of a DSA. Results Three hundred sixty-one patients met inclusion criteria. Three hundred six patients (85%) had a CT scan, 55 (15%) had an ultrasound and 33 (9%) had both. DSA was identified in 71 (20%) patients. Clinical features independently associated with a DSA included absence of clinical pharyngitis, WBC >15,000/mm3, age ≤3 years, anterior cervical chain location, largest palpable diameter on exam >3 cm and prior antibiotic treatment of >24 h. The presence of fever, skin erythema, or fluctuance on examination, was not found to be predictive of DSA. Conclusions We identified independent predictors of DSA among children presenting with cervical adenitis. Risk can be stratified into risk groups based on these clinical features.

To determine the yield of neuroimaging in children presenting to the emergency department with acute ataxia in the post–varicella vaccine era, we conducted a cross-sectional study between 1995 and 2013 at a single pediatric tertiary care center. We included children aged 1-18 years evaluated for acute ataxia of

We sought to identify specific mechanisms leading to radial head subluxation, as well as correlation with different caregivers, as a potential platform for education and injury prevention.A retrospective cohort study of all patients admitted to an urban pediatric tertiary care emergency department with radial head subluxation from 1995 to 2009 was performed. Cases were identified using a text-search module followed by a manual chart review. We excluded patients with fractures, osteopenia, and neuromuscular conditions. Data collected included age, gender, arm involved, position of the arm at presentation, mechanism of injury, caregivers involved, imaging, and type of reduction. Multivariate logistic regression analysis was used to determine predictors for different mechanisms.There were 3170 cases of radial head subluxation identified. The median age was 2.1 years (interquartile range, 1.5-2.8 years), and 59% were female (95% confidence interval [CI], 57%-60%). There were 2011 patients (63%) presenting with a traction mechanism, 547 (17%) with a nontraction traumatic mechanism, and 612 (19%) with an unknown or undocumented mechanism.Within the traction group, we identified several potentially preventable mechanisms including lifting the child by the arms (28.3%), "wrestling" (12.3%), swinging child by the arms (9.2%), and placing the child into and out of a seat (4.3%). Male caregivers were more likely to be involved when a child is swung by the arms (odds ratio [OR], 3.2; 95% CI, 1.6-6.2), lifted (OR, 1.9; 95% CI, 1.4-2.7), or "wrestled" with (OR, 6.4; 95% CI, 3.3-12.0). Mechanisms common for female caregivers included the child pulling away from parent (OR, 2.3; CI, 1.54 3.4), tripping (2.0; CI, 1.3-3.0), and getting dressed (OR, 2.1; CI, 1.1-4.4).Radial head subluxation mechanisms can be classified into subcategories, which may be caregiver and even patient gender specific. Provider awareness regarding these mechanisms may help target education and prevention.

OBJECTIVE:To assess the rate of acute bacterial meningitis (ABM) among children who present with their first complex febrile seizure (CFS).DESIGN AND METHODS:This study was a retrospective, cohort review of patients aged 6 to 60 months who were evaluated in a pediatric emergency department (ED) between 1995 and 2008 for their first CFS. Cases were identified by using a computerized text search followed by a manual chart review. Exclusion criteria included prior history of nonfebrile seizures, an immunocompromised state, an underlying illness associated with seizures or altered mental status, or trauma. Data extracted included age, gender, seizure features, the number of previous simple febrile seizures, temperature, a family history of seizures, findings on physical examination, laboratory and imaging study results, and ED diagnosis and disposition.RESULTS:We identified 526 patients. The median age was 17 months (interquartile range: 13–24), and 44% were female. Ninety patients (17%) had a previous history of simple febrile seizures. Of the patients, 340 (64%) had a lumbar puncture (LP). The patients' median white blood cell count during a CFS was 1 cell per μL (interquartile range: 1–2), and 14 patients had CSF pleocytosis (2.7% [95% confidence interval [CI]: 1.5–4.5]). Three patients had ABM (0.9% [95% CI: 0.2–2.8]). Two had Streptococcus pneumoniae in a culture of their cerebrospinal fluid. Among these 2 patients, 1 was nonresponsive during presentation, and the other had a bulging fontanel and apnea. The third child appeared well; however, her blood culture grew S pneumoniae and failed the LP test. None of the patients for whom an LP was not attempted subsequently returned to the hospital with a diagnosis of ABM (0% [95% CI: 0, 0.9]).CONCLUSION:Few patients who experienced a CFS had ABM in the absence of other signs or symptoms.

OBJECTIVES:Computed tomography (CT) is used often in the evaluation of orbital infections to identify children who are most likely to benefit from surgical intervention. Our objective was to identify predictors for intraorbital or intracranial abscess among children who present with signs or symptoms of periorbital infection. These predictors could be used to better target patients for emergent CT.METHODS:This was a retrospective cohort study of all patients admitted to an urban pediatric tertiary care emergency department between 1995 and 2008. We included otherwise healthy patients with suspected acute clinical periorbital or orbital cellulitis without a history of craniofacial surgery, trauma, or external source of infection. Immunocompromised patients and patients with noninfectious causes of periorbital swelling were excluded. Variables analyzed included age, duration of symptoms, highest recorded temperature, previous antibiotic therapy, physical examination findings, laboratory results, and interpretation of imaging. CT scans of the orbit were reread by a neuroradiologist.RESULTS:Nine hundred eighteen patients were included; 298 underwent a CT scan, and of those, 111 were shown to have an abscess. Although proptosis, pain with external ocular movement, and ophthalmoplegia were associated with presence of an abscess, 56 (50.5%) patients with abscess did not experience these symptoms. Other variables associated with the presence of an abscess in multivariate analysis were a peripheral blood neutrophil count greater than 10 000/μL, absence of infectious conjunctivitis, periorbital edema, age greater than 3 years, and previous antibiotic therapy (P < .05 for all). Our recursive partitioning model identified all high-risk (44%) patients as well as a low-risk (0.4%–2%) group (Rsq = 0.27).CONCLUSIONS:We confirmed that patients with proptosis and/or pain or limitation of extraocular movements are at high risk for intraorbital abscess, yet many do not have these predictors. Other features can identify patients who do not have such obvious predictors but do have significant risk of disease. A recursive partitioning model is presented.

The objective of this study was to assess the risk of intracranial pathology requiring immediate intervention among children presenting with their first complex febrile seizure (CFS).This is a retrospective cohort review of patients 6 to 60 months of age evaluated in a pediatric emergency department between 1995 and 2008 for their first CFS. Cases were identified using computerized text search followed by manual chart review. We excluded patients with a prior history of a nonfebrile seizure disorder or a prior CFS, an immune-compromised state, an underlying illness associated with seizures or altered mental status, or trauma. Data extraction included age, sex, seizure features, prior simple febrile seizures, temperature, family history of seizures, vaccination status, findings on physical examination, laboratory and imaging studies, diagnosis, and disposition.We identified a first CFS in 526 patients. Two hundred sixty-eight patients (50.4%) had emergent head imaging: 4 patients had a clinically significant finding: 2 had intracranial hemorrhage, 1 had acute disseminated encephalomyelitis, and 1 patient had focal cerebral edema (1.5%; 95% confidence interval, 0.5%-4.0%). Assigning low risk to patients not imaged and not returning to the emergency department within a week of the original visit, the risk of intracranial pathology in our sample was 4 (0.8%; 95% confidence interval, 0.2%-2.1%) of 526. Three of these 4 patients had other obvious findings (nystagmus, emesis, and altered mental status; persistent hemiparesis; bruises suggestive of inflicted injury).Very few patients with CFSs have intracranial pathology in the absence of other signs or symptoms. Patients presenting with more than one seizure in 24 hours in particular are at very low risk.
