Pediatric Hypereosinophilia: Characteristics, Clinical Manifestations, and Diagnoses.

ABSTRACT: BACKGROUND:Eosinophilia is associated with various conditions, including allergic, infectious, and neoplastic disorders. The diagnostic differential is broad, and data on hypereosinophilia in pediatric patients are limited. OBJECTIVE:The objectives of this study were to identify cases of hypereosinophilia in a tertiary pediatric medical center, determine clinical characteristics and disease associations, and estimate the incidence of hypereosinophilia in the hospital and geographic populations. METHODS:A retrospective chart review included patients younger than 18 years presenting to a tertiary pediatric medical center (January 1, 2008, to May 31, 2017) with absolute eosinophil counts (AECs) greater than or equal to 1.50 thousand eosinophils/microliter (K/?L) recorded on at least 2 occasions at least 4 weeks apart (N = 176). Clinical characteristics, laboratory values, treatment course, and associated diagnoses were evaluated. RESULTS:The most common cause of hypereosinophilia in this cohort was secondary hypereosinophilia. Atopic dermatitis, graft-versus-host disease, sickle cell disease, and parasitic infections were the most common conditions associated with hypereosinophilia. Median age at diagnosis was 4.6 (interquartile range, 1.5-10.5) years. Median peak AEC was 3.16 (2.46-4.78) K/?L. Hypereosinophilia occurred most frequently in patients aged between 6 and 11 years (24.4%) and younger than 1 year (18.2%). Patients with neoplasms and immune deficiencies had significantly higher peak AECs than did patients with overlap hypereosinophilic syndrome and atopic diseases (P < .0001). CONCLUSIONS:Pediatric hypereosinophilia has an incidence of 54.4 per 100,000 persons per year, with children younger than 1 year and aged 6 to 11 years accounting for most affected patients. Pediatric hypereosinophilia is not uncommon and remains underrecognized, highlighting a need for clinicians to identify patients who meet criteria for hypereosinophilia and to pursue a thorough evaluation.

Project description:ObjectiveNew-onset seizure-like events (SLEs) are common in children, but differentiating between epilepsy and its mimics is challenging. This study provides an overview of the clinical characteristics, diagnoses, and corresponding etiologies of children evaluated at a first seizure clinic (FSC), which will be helpful for all physicians involved in the care of children with SLEs.MethodsWe included 1213 children who were referred to the FSC of a Dutch tertiary children's hospital over a 13-year period and described their clinical characteristics, first routine EEG recording results, and the distribution and specification of their eventual epilepsy and non-epilepsy diagnoses. The time interval to correct diagnosis and the diagnostic accuracy of the FSC were evaluated.Results"Epilepsy" was eventually diagnosed in 407 children (33.5%), "no epilepsy" in 737 (60.8%), and the diagnosis remained "unclear" in 69 (5.7%). Epileptiform abnormalities were seen in 60.9% of the EEG recordings in the "epilepsy" group, and in 5.7% and 11.6% of the "no epilepsy" and "unclear" group, respectively. Of all children with final "epilepsy" and "no epilepsy" diagnoses, 68.6% already received their diagnosis at FSC consultation, and 2.9% of the children were initially misdiagnosed. The mean time to final diagnosis was 2.0 months, and 91.3% of all children received their final diagnosis within 12 months after the FSC consultation.SignificanceWe describe the largest pediatric FSC cohort to date, which can serve as a clinical frame of reference. The experience and expertise built at FSCs will improve and accelerate diagnosis in children with SLEs.Plain language summaryMany children experience events that resemble but not necessarily are seizures. Distinguishing between seizures and seizure mimics is important but challenging. Specialized first-seizure clinics can help with this. Here, we report data from 1213 children who were referred to the first seizure clinic of a Dutch children's hospital. One-third of them were diagnosed with epilepsy. In 68.8% of all children-with and without epilepsy-the diagnosis was made during the first consultation. Less than 3% were misdiagnosed. This study may help physicians in what to expect regarding the diagnoses in children who present with events that resemble seizures.

Project description:IntroductionMethamphetamine toxicity is common in the Southwest region of the United States and presents diagnostic and treatment challenges in the pediatric population. The aim of our study was to characterize signs and symptoms of methamphetamine toxicity in pediatric patients, highlighting manifestations unique to this population. Additionally, our study sought to evaluate treatment modalities, specifically antipsychotics, in this population with the intent to characterize their adverse effects.MethodsThis is a retrospective review of pediatric patients (age > 2 months ≤ 18 years) at a tertiary care pediatric hospital with ICD-9 or ICD-10 codes suggestive of stimulant exposure between September 1, 2010, and July 31, 2017. Patients with clinical manifestations of sympathomimetic toxicity and confirmation of methamphetamine on urine drug testing via GC/MS were included. Nature, source, and route of exposure along with clinical manifestations including signs, complications, treatments utilized, and adverse events related to treatment were recorded. Specifically, adverse effects following administration of antipsychotics were studied.ResultsSeventy-nine patients met inclusion criteria: median age 2.0 years. Typical manifestations of sympathomimetic toxicity were common, including tachycardia (93.4%), hypertension (85.7%), agitation (79.7%), and abnormal motor activity (55.8%). The prominence of gastrointestinal signs (26.3%) and unique abnormal motor activity were notable. The most common treatments were intravenous fluids (96.1%) and benzodiazepines (77.9%). Antipsychotics were administered in 40.5% of cases, with haloperidol used in the majority. No patients developed seizures, dystonia, torsades de pointes, or hyperthermia after antipsychotic administration.ConclusionsPediatric patients with methamphetamine toxicity commonly manifest sympathomimetic signs. Antipsychotics were often used as an adjunct treatment in this cohort of patients, and no adverse events were reported. Clinicians should be aware of prominent gastrointestinal signs and abnormal motor activity and neurologic manifestations unique to pediatric patients that will assist in making the correct diagnosis in cases of suspected methamphetamine toxicity.

Project description:ObjectivesSevere sepsis is a significant cause of healthcare use and morbidity among pediatric patients, but little is known about readmission diagnoses. We sought to determine the most common readmission diagnoses after pediatric severe sepsis, the extent to which post-sepsis readmissions may be potentially preventable, and whether patterns of readmission diagnoses differ compared with readmissions after other common acute medical hospitalizations.DesignObservational cohort study.SettingNational Readmission Database (2013-2014), including all-payer hospitalizations from 22 states.PatientsFour-thousand five-hundred twenty-eight pediatric severe sepsis hospitalizations, matched by age, gender, comorbidities, and length of stay to 4,528 pediatric hospitalizations for other common acute medical conditions.InterventionsNone.Measurements and main resultsWe compared rates of 30-day all cause, diagnosis-specific, and potentially preventable hospital readmissions using McNemar's chi-square tests for paired data. Among 5,841 eligible pediatric severe sepsis hospitalizations with live discharge, 4,528 (77.5%) were matched 1:1 to 4,528 pediatric hospitalizations for other acute medical conditions. Of 4,528 matched sepsis hospitalizations, 851 (18.8% [95% CI, 16.0-18.2]) were rehospitalized within 30 days, compared with 775 (17.1% [95% CI, 17.1-20.0]) of matched hospitalizations for other causes (p = 0.02). The most common readmission diagnoses were chemotherapy, device complications, and sepsis, all of which were several-fold higher after sepsis versus after matched nonsepsis hospitalization. Only 11.5% of readmissions were for ambulatory care sensitive conditions compared with 23% of rehospitalizations after common acute medical conditions.ConclusionsMore than one in six children surviving severe sepsis were rehospitalized within 30 days, most commonly for maintenance chemotherapy, medical device complications, or recurrent sepsis. Only a small proportion of readmissions were for ambulatory care sensitive conditions.
