Severe respiratory illness associated with enterovirus D68 - Missouri and Illinois, 2014.

On August 19, 2014, CDC was notified by Children's Mercy Hospital in Kansas City, Missouri, of an increase (relative to the same period in previous years) in patients examined and hospitalized with severe respiratory illness, including some admitted to the pediatric intensive care unit. An increase also was noted in detections of rhinovirus/enterovirus by a multiplex polymerase chain reaction assay in nasopharyngeal specimens obtained during August 5-19. On August 23, CDC was notified by the University of Chicago Medicine Comer Children's Hospital in Illinois of an increase in patients similar to those seen in Kansas City. To further characterize these two geographically distinct observations, nasopharyngeal specimens from most of the patients with recent onset of severe symptoms from both facilities were sequenced by the CDC Picornavirus Laboratory. Enterovirus D68 (EV-D68) was identified in 19 of 22 specimens from Kansas City and in 11 of 14 specimens from Chicago. Since these initial reports, admissions for severe respiratory illness have continued at both facilities at rates higher than expected for this time of year. Investigations into suspected clusters in other jurisdictions are ongoing.

Infectious Diseases and Immunizations in International Adoption.

Children who are adopted internationally have an increased risk of infectious diseases due to endemic conditions and variable access to preventive health care, such as vaccines, in their country of origin. Pediatricians and other providers who care for children should be familiar with the recommended screening for newly arrived international adoptees. Testing for gastrointestinal pathogens, tuberculosis, hepatitis, syphilis, and HIV should be routinely performed. Other endemic diseases and common skin infections may need to be assessed. Evaluation of the child's immunization record is also important, as nearly all international adoptees will require catch-up vaccines. The provider may also be asked to review medical records prior to adoption, provide travel advice, and ensure that parents and other close contacts are up-to-date on immunizations prior to the arrival of the newest family member. The pediatrician serves a unique role in facilitating the evaluation, treatment, and prevention of infectious diseases in international adoptees. [Pediatr Ann. 2017;46(2):e56-e60.].

Risk of Second Seizure in Pediatric Patients With Idiopathic Autism.

PURPOSE: Epilepsy is a comorbidity of idiopathic autism spectrum disorder. The aim was to characterize the risk and time of second seizure in children with idiopathic autism spectrum disorder. METHODS: A retrospective review was performed at the University of Chicago and NorthShore University HealthSystem. Patients with idiopathic autism spectrum disorder, ≥1 seizure, and age 2 to 23 years were included. RESULTS: 153 patients were included; 141 (92%) had a second seizure. The average age at first seizure was 7.14 years (median: 5.08 years) and 8.12 years (median: 7.3 years) at second seizure. Average time between first and second seizure was 7.68 months. DISCUSSION: A high risk of seizure recurrence was found in this population. There was a short time to second seizure, with most having a recurrence within 1 year. These findings may be used to guide therapy in children with autism spectrum disorder and epilepsy.

Acute Mastoiditis Caused by Streptococcus pneumoniae.

Acute mastoiditis (AM) is a relatively rare complication of acute otitis media (AOM). The most common pathogens include Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus. Pneumococcal vaccination and changes in antibiotic prescribing recommendations for AOM may change the incidence of AM in the future. Diagnosis of AM can be made based on clinical presentation, but computed tomography of the temporal bone with contrast should be considered if there is concern for complicated AM. Both extracranial and intracranial complications of AM may occur. Previously, routine cortical mastoidectomy was recommended for AM treatment, but new data suggest that a more conservative treatment approach can be considered, including intravenous (IV) antibiotics alone or IV antibiotics with myringotomy.

Outpatient Management of Febrile Children With Sickle Cell Disease.

The electronic medical records at 2 children's hospitals were reviewed from June 1, 2011 to May 31, 2013 for all patients with sickle cell disease who presented with fever. Of a total of 390 blood cultures drawn, 11 cultures (2.8%) turned positive with only 1 (0.3%) growing a true pathogen. This culture turned positive in 13 hours. There were 154 patients who received exclusive outpatient management of fever. Fourteen patients (9.1%) completed 1 acute care visit, 16 patients (10.4%) completed 2 acute care visits, and 124 patients (80.5%) completed 3 acute care visits. Of those treated exclusively as outpatients, there was 1 positive culture that was considered a contaminant. Although the overall rate of positivity was low, this study confirms previous findings that pediatric blood cultures become positive with pathogens within 48 hours. Given the high rate of compliance and early time to positivity of true pathogens, we suggest that follow-up for the febrile sickle cell disease patients can be treated on an outpatient basis.

Neonatal tuberculosis.

Tuberculosis remains a prevalent disease worldwide, with approximately 9 million cases diagnosed annually. The emergence of multidrug-resistant tuberculosis has proven to be a challenging international public health issue. In the United States, however, the incidence of tuberculosis has been decreasing since 1992. There were just over 9,500 reported cases in 2013, and almost 500 of those were in children younger than age 15 years. Foreign-born persons are a high-risk group and account for 65% of new cases annually. Other high-risk groups include ethnic minorities, HIV-infected patients, and people living in low-socioeconomic urban areas.

Severe respiratory illness associated with a nationwide outbreak of enterovirus D68 in the USA (2014): a descriptive epidemiological investigation.

BACKGROUND: Enterovirus D68 (EV-D68) has been infrequently reported historically, and is typically associated with isolated cases or small clusters of respiratory illness. Beginning in August, 2014, increases in severe respiratory illness associated with EV-D68 were reported across the USA. We aimed to describe the clinical, epidemiological, and laboratory features of this outbreak, and to better understand the role of EV-D68 in severe respiratory illness. METHODS: We collected regional syndromic surveillance data for epidemiological weeks 23 to 44, 2014, (June 1 to Nov 1, 2014) and hospital admissions data for epidemiological weeks 27 to 44, 2014, (June 29 to Nov 1, 2014) from three states: Missouri, Illinois and Colorado. Data were also collected for the same time period of 2013 and 2012. Respiratory specimens from severely ill patients nationwide, who were rhinovirus-positive or enterovirus-positive in hospital testing, were submitted between Aug 1, and Oct 31, 2014, and typed by molecular sequencing. We collected basic clinical and epidemiological characteristics of EV-D68 cases with a standard data collection form submitted with each specimen. We compared patients requiring intensive care with those who did not, and patients requiring ventilator support with those who did not. Mantel-Haenszel χ(2) tests were used to test for statistical significance. FINDINGS: Regional and hospital-level data from Missouri, Illinois, and Colorado showed increases in respiratory illness between August and September, 2014, compared with in 2013 and 2012. Nationwide, 699 (46%) of 1529 patients tested were confirmed as EV-D68. Among the 614 EV-D68-positive patients admitted to hospital, age ranged from 3 days to 92 years (median 5 years). Common symptoms included dyspnoea (n=513 [84%]), cough (n=500 [81%]), and wheezing (n=427 [70%]); 294 (48%) patients had fever. 338 [59%] of 574 were admitted to intensive care units, and 145 (28%) of 511 received ventilator support; 322 (52%) of 614 had a history of asthma or reactive airway disease; 200 (66%) of 304 patients with a history of asthma or reactive airway disease required intensive care compared with 138 (51%) of 270 with no history of asthma or reactive airway disease (p=0·0004). Similarly, 89 (32%) of 276 patients with a history of asthma or reactive airway disease required ventilator support compared with 56 (24%) of 235 patients with no history of asthma or reactive airway disease (p=0·039). INTERPRETATION: In 2014, EV-D68 caused widespread severe respiratory illness across the USA, disproportionately affecting those with asthma. This unexpected event underscores the need for robust surveillance of enterovirus types, enabling improved understanding of virus circulation and disease burden. FUNDING: None.

Children with autism spectrum disorder and epilepsy.

Autism spectrum disorder (ASD) is a biologically based neurodevelopmental disability characterized by qualitative and persistent deficits in social communication and social interaction and by the presence of restricted, repetitive, and stereotyped patterns of behavior. Symptoms must be present in early childhood and they must limit and impair everyday functioning. There is an increased prevalence of epilepsy and/or epileptiform electroencephalography (EEG) abnormalities in children with ASD. It is estimated that approximately one-third of children and adolescents with ASD experience seizures, but the relationship between epilepsy and autism is controversial. This article reviews the types of seizures associated with ASD, the EEG findings, and current treatment strategies. The article also describes syndromes associated with the autism phenotype and epilepsy.
