In this study we examined the relationship between diagnoses of isolated intrapartum fever or chorioamnionitis and the risk of encephalopathy in term newborns. We conducted a population-based, case-control study in Washington State using 1994 to 2002 linked data from the Washington State Birth Registry and the Comprehensive Hospital Abstract Reporting System (CHARS). We identified 1060 singleton, term newborns (602 males, 458 females) with International Classification of Diseases (ICD-9) diagnoses consistent with encephalopathy, and 5330 unaffected control newborns (2756 males, 2574 females). Intrapartum fever was defined by a diagnosis of intrapartum temperature of >38 degrees C in the birth registry or CHARS databases. Chorioamnionitis was defined using ICD-9 diagnoses recorded in CHARS. We identified 2.2 cases of encephalopathy per 1000 births. Isolated intrapartum fever was associated with a 3.1-fold (95% confidence interval [CI] 2.3-4.2) increased risk of newborn encephalopathy. Chorioamnionitis was associated with a 5.4-fold (95% CI 3.6-7.8) increased risk of encephalopathy. We found that isolated intrapartum fever and chorioamnionitis were independently associated with an increased risk of encephalopathy in term infants. Our data also indicate that there is a spectrum of risk for encephalopathy in term infants exposed to intrapartum fever. Infants born to women with signs of chorioamnionitis other than isolated intrapartum fever may be at higher risk of encephalopathy than those exposed only to isolated intrapartum fever.

Background: Posttraumatic headache is common in pediatrics. Studies have examined treatment of postconcussion symptoms, but few target posttraumatic headache. Biofeedback therapy has been studied in children and teens with primary headaches, but not posttraumatic headache. Our goal was to examine the changes in posttraumatic headache associated with biofeedback therapy in pediatric patients., Methods: This retrospective study included 74 children aged 10-18 years who received biofeedback therapy for posttraumatic headache. "Positive response" to biofeedback therapy was defined as ≥50% reduction in headache days per week, or 3-point drop in pain rating between the first and last biofeedback therapy visits. Patient characteristics were analyzed using logistic regression to identify factors associated with response., Results: In our cohort, 42% of all patients with posttraumatic headache had a positive response to biofeedback therapy. Thirty-six percent experienced ≥50% decrease in headache frequency, 13% had a ≥3-point decrease in headache severity and 8% reported both changes. For those with daily headaches, 36% had a positive response to biofeedback therapy. School absences, selective serotonin reuptake inhibitor or prescription preventive medication use were associated with nonresponse., Conclusions: Biofeedback therapy is a reasonable treatment to consider to manage pediatric posttraumatic headache because more than 40% of our cohort had a beneficial response and biofeedback therapy has few adverse effects., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose of Review: To summarize recent findings regarding triptan use in the acute treatment of pediatric migraine., Recent Findings: Prevalence of pediatric migraine is rising. The American Headache Society and American Academy of Neurology updated guidelines to provide evidence-based recommendations for the treatment of acute migraine in youth. In the setting of a dearth of new randomized controlled trials (RCTs), we review current guidelines, triptan use in the emergency department, and an era of secondary analyses. Measuring the efficacy of triptans in pediatric migraine has been challenged by high placebo response rates. Secondary analyses, combining data from multiple RCTs, support that triptans are safe and effective in the treatment of migraine. Triptans are a vital tool and the only FDA-approved migraine-specific treatment available in pediatrics. There is a need for further studies and funding support in pediatric headache medicine., (© 2024.

Importance: The Four Corners Youth Consortium was created to fill the gap in our understanding of youth concussion. This study is the first analysis of posttraumatic headache (PTH) phenotype and prognosis in this cohort of concussed youth., Objective: To describe the characteristics of youth with PTH and determine whether the PTH phenotype is associated with outcome., Design, Setting, and Participants: This cohort study examined outcomes from patients in a multi-institutional registry of traumatic brain injury (TBI) clinics from December 2017 to June 2019. Inclusion criteria included being between ages 5 and 18 years at enrollment and presentation within 8 weeks of a mild TBI. Data were analyzed between February 2019 and January 2021., Exposure: Mild TBI with standard care., Main Outcomes and Measures: Time to recovery and headache 3 months after injury; measurement device is the Postconcussion Symptom Inventory (PCSI). PTH with migraine phenotype was defined as moderate-severe headache that is new or significantly worse compared with baseline and associated with nausea and/or photophobia and phonophobia., Results: A total of 612 patients with 625 concussions were enrolled, of whom 387 patients with 395 concussions consented to participate in this study. One hundred nine concussions were excluded (concussions, rather than patients, were the unit of analysis), leaving 281 participants with 286 concussions (168 [58.7%] girls; 195 [75.6%] White; 238 [83.2%] aged 13-18 years). At the initial visit, 133 concussions (46.5%) were from patients experiencing PTH with a migraine phenotype, 57 (20%) were from patients experiencing PTH with a nonmigraine phenotype, and 96 (34%) were from patients with no PTH. Patients with any PTH after concussion were more likely to have prolonged recovery than those without PTH (median [interquartile range], 89 [48-165] days vs 44 [26-96] days; log-rank P < .001). Patients with PTH and a migraine phenotype took significantly longer to recover than those with nonmigraine phenotype (median [interquartile range], 95 [54-195] days vs 70 [46-119] days; log-rank P = .01). Within each phenotype, there was no significant difference between sexes in recovery or PTH at 3 months., Conclusions and Relevance: PTH with a migraine phenotype is associated with persistent symptoms following concussion compared with nonmigraine PTH or no PTH. Given that female sex is associated with higher rates of migraine and migraine PTH, our finding may be one explanation for findings in prior studies that girls are at higher risk for persistent postconcussion symptoms than boys.

Purpose of Review: Headache following concussion and mild traumatic brain injury is very common in pediatrics. There is significant concern about appropriate management of acute and persistent headache following mild head injuries in children among affected youth, their families and care providers., Recent Findings: The current article will review definitions and diagnoses of posttraumatic headache (PTHA), recent research regarding risk factors for persistence of postconcussion symptoms and headaches, current recommendations for the evaluation of youth with PTHA, recent data regarding efficacy of treatment options for PTHA, and current recommendations for the treatment of acute and persistent PTHA., Summary: PTHA is common following concussion in pediatrics. Some of the most consistent risk factors for persistent symptoms following concussion include female sex, adolescent age, prior concussion with prolonged recovery, prior headache history and high number of acute symptoms, particularly migrainous symptoms, following concussion. There are few prospective studies of the treatment of PTHA in pediatrics; however, a recent study found that short-term use of ibuprofen for those with acute PTHA following concussion may be associated with lower risk of symptoms and better function 1 week after injury. Currently complete rest or cocooning following concussion is not recommended as it may actually be associated with longer recovery time; a gradual return to cognitive and physical activity appears to be most effective strategy but more study is needed.

Headache occurring in a sports setting may be primary or secondary headache. Headache is the primary symptom reported after concussion. Cumulative incidence and prevalence of posttraumatic headache (PTH) are higher following mild traumatic brain injury (TBI) compared with moderate to severe TBI. Frequency is higher in those with more severe PTH. Migraine or probable migraine is the most common headache type after any severity TBI using primary headache disorder criteria. Management is empiric. Expert opinion recommends treating PTH according to clinical characteristics of primary headache. The most important factor in this approach is the recognition of the severity of headache., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Headaches are common in childhood and adolescence and can cause significant distress and disability for a child and their family. Providers need to be able to identify "red flags" for worrisome causes of secondary headaches and recognize typical primary headache characteristics to provide each patient with the best possible care to improve their quality of life and minimize disability. This article reviews the epidemiology of headaches in children, signs and symptoms of secondary headaches, definitions of some primary childhood headaches, and options for management of both acute and chronic pediatric migraine.

Purpose: To determine if there are differences in the timing of diagnosis and response to treatment between infants with infantile spasms (IS) and Trisomy 21 (T21) and those with idiopathic IS., Method: This was a retrospective study evaluating the time from onset of IS to diagnosis, treatment of IS, time from treatment to resolution of IS, and development of epilepsy in children with T21 and IS compared to children with idiopathic IS., Results: Thirteen children with T21 and IS were identified over a 10 year period and compared to 32 children in the control group. There was no significant difference in age of onset, time between onset and diagnosis, or acute response to treatment. However, the children with idiopathic IS were more likely to go on to develop epilepsy than those with T21 and IS (41% vs. 0, p=0.006)., Conclusion: The children with T21 and IS were diagnosed and treated similarly to those patients with idiopathic IS. There were no significant differences in the age of onset, time between the onset and diagnosis of IS, or acute treatment response of IS between the T21 and control groups. However those with T21 and IS had a lower risk of subsequent epilepsy following IS than those with idiopathic IS. IS in the T21 population appears to be inherently different from IS of unknown etiology., (Copyright © 2017 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.)

Concussion and mild traumatic brain injury are common injuries in pediatrics, and posttraumatic headache is the most common complaint following them. Although most children and teens recover from a simple, isolated concussion without incidents within 1-2 weeks, some develop symptoms that can last for months. It is important to manage both acute and persistent posttraumatic headaches appropriately to speed recovery, minimize disability, and maximize function. In this article, we review the definitions, epidemiology, and current recommendations for the evaluation and treatment of acute and persistent posttraumatic headaches. Although this is still a developing field and there is much that we still need to learn about concussion and the best strategies to prevent and treat these injuries and their sequelae, we hope that this review will help providers to understand the current evidence and treatment recommendations to improve care for children with concussion and mild traumatic brain injury., (Copyright © 2016 Elsevier Inc.

Head injuries are common in pediatrics, and headaches are the most common complaint following mild head trauma. Although moderate and severe traumatic brain injuries occur less frequently, headaches can complicate recovery. There is currently an intense spotlight on concussion and there has been a corresponding increase in the number of children seeking care for headache after mild traumatic brain injury or concussion. Understanding the natural history of, and recognition of factors that are associated with posttraumatic headache will help providers and families to limit disability and may prompt earlier intervention to address disabling headaches. While there are few studies on the treatment of posttraumatic headache, proper evaluation and management of posttraumatic headaches is essential to prevent further injury and to promote recovery. In this article, we will review the current definitions and epidemiology of pediatric posttraumatic headache and discuss current recommendations for the evaluation and management of this syndrome in children and adolescents., (© The Author(s) 2015.)

Concussion and mild traumatic brain injury (TBI) are common pediatric injuries. Headaches are one of the most common and disabling complaints following concussion in the acute phase and are pervasive in those who have prolonged symptoms following concussion. The body of evidence regarding the epidemiology of and risk factors for pediatric concussion and post-traumatic headache is growing rapidly, but there still is a distinct lack of strong scientific evidence to support the best treatment strategies for post-traumatic headaches in either children or adults. In this article, we will review the current evidence regarding the epidemiology of acute and chronic headaches following concussion in the pediatric population, as well as current recommendations for the management of acute and chronic pediatric post-traumatic headaches.

Objectives: The goal of this study was to measure the effect of biofeedback therapy on pediatric headache and to identify factors associated with response to biofeedback therapy., Background: In the United States, 17% of children have frequent or severe headaches. Biofeedback therapy (BFT) appears to be an effective treatment for headaches in adults and is often recommended for children with headaches, but there are few data in the pediatric population. It is also not clear which patients are most likely to benefit from biofeedback therapy., Methods: We examined the records of patients, aged 8 to 18 years old, who were referred to a pediatric BFT clinic for management of headache between 2004 and 2008. We extracted data regarding patient and headache characteristics, medication use, family history, and measures of depression, anxiety, and somatization. Chronic headache was defined as ≥4 headache days/week. Positive response to biofeedback was defined as a 50% reduction in number of headache days/week or hours/week, or ≥3-point decrease in severity (0-10 scale) between first and last visits. We analyzed the responder rate for those with episodic and chronic headaches and performed multivariable analysis to determine what factors were associated with headache response to biofeedback therapy., Results: We analyzed records from 132 children who attended ≥2 biofeedback sessions. Median headache frequency dropped from 3.5 to 2 headache days/week between the first and last visits. The response rate was 58% overall; 48% for chronic headaches and 73% episodic headaches. In multivariate analysis, ability to raise hand temperature by >3°F at the last visit and use of selective serotonin reuptake inhibitors (SSRIs) were associated with a positive response, and preventive medication use was associated with nonresponse. Anxiety, depression, and somatization were not significantly associated with response to biofeedback therapy., Conclusions: Biofeedback therapy appears to be an effective treatment for children and adolescents with both episodic and chronic headaches. Further study is warranted to compare biofeedback with other treatments for chronic pediatric headache. Use of SSRIs appears to be associated with a positive response to biofeedback therapy, but the reasons for this relationship are unclear and merit further study., (© 2012 American Headache Society.)

Objective: To determine the prevalence of headache 3 and 12 months after pediatric traumatic brain injury (TBI)., Methods: This is a prospective cohort study of children ages 5 to 17 years in which we analyzed the prevalence of headache 3 and 12 months after mild TBI (mTBI; n = 402) and moderate/severe TBI (n = 60) compared with controls with arm injury (AI; n = 122)., Results: The prevalence of headache 3 months after injury was significantly higher after mTBI than after AI overall (43% vs 26%, relative risk [RR]: 1.7 [95% confidence interval (CI): 1.2-2.3]), in adolescents (13-17 years; 46% vs 25%, RR: 1.8 [95% CI: 1.1-3.1]), and in girls (59% vs 24%, RR: 2.4 [95% CI: 1.4-4.2]). The prevalence of headache at 3 months was also higher after moderate/severe TBI than AI in younger children (5-12 years; 60% vs 27%; RR: 2.0 [95% CI: 1.2-3.4]). Twelve months after injury, TBI was not associated with a significantly increased frequency of headache. However, girls with mTBI reported serious headache (≥ 5 of 10 pain scale rating) more often than controls (27% vs 10%, RR: 2.2 [95% CI: 0.9-5.6])., Conclusions: Pediatric TBI is associated with headache. A substantial number of children suffer from headaches months after their head injury. The prevalence of headache during the year after injury is related to injury severity, time after injury, age, and gender. Girls and adolescents appear to be at highest risk of headache in the months after TBI.

Most athletes who experience a sports-related concussion recover from the acute effects within a few weeks. However, some children and adolescents with concussion experience symptoms for many weeks, or even months after the injury. Subacute and chronic symptoms related to concussion are particularly concerning in children, because cognitive deficits, headache or neck pain, sleep dysfunction, and emotional dysregulation can affect school performance and social function at a critical period of development and maturation. This article reviews the epidemiology of subacute symptoms after pediatric concussion and the current recommendations for the assessment and management of these symptoms in children and adolescents., (Copyright © 2011 Elsevier Inc.

Background: Seizures are common in children, but the causes and recurrence risk for children with a nonfebrile first seizure remain poorly understood., Objective: In a prospective longitudinal study of children who presented with a first-time seizure, we investigated the viral etiology of associated infectious illnesses and sought to determine the risk of recurrent seizures stratified by fever and type of illness., Patients and Methods: Children (aged 6 months to 6 years) were enrolled at the time of evaluation for their first seizure and followed monthly for up to 5 years. Seizure and illness data were collected through parent interviews and medical-record reviews. Stool, serum, and cerebrospinal fluid collected within 48 hours of the first seizure were evaluated for viral gastrointestinal pathogens., Results: Of the 117 children enrolled, 78 (67%) had febrile seizures, 34 (29%) had nonfebrile-illness seizures, and 5 (4%) had unprovoked seizures. Children with nonfebrile-illness seizures were more likely than those with febrile seizures to have acute gastroenteritis (47% and 28%, respectively; P = .05). No significant differences in seizure recurrence were found between children with or without a fever at first seizure. Children with acute gastroenteritis at first seizure, regardless of fever, had a lower risk of seizure recurrence compared with children with other acute illnesses (hazard ratio: 0.28; 95% confidence interval: 0.09-0.80)., Conclusions: Our results confirm the role of gastrointestinal illness as a distinguishing feature in childhood seizures. Children with this distinct presentation have a low rate of seizure recurrence and few neurologic complications.

Neonatal seizures are one of the most common neurological disorders in infants. However, the optimal treatment strategy for neonatal seizures remains controversial and there is little data regarding current treatment of neonatal seizures. In this study we describe the current treatment of neonatal seizures and variation in practice among 31 pediatric hospitals in the United States. We retrospectively identified 6099 infants hospitalized in the first month of life in one of 31 pediatric hospitals participating in the Pediatric Health Information System, with a discharge diagnosis of seizure. As expected, most treated infants received phenobarbital. However, there was significant interhospital variability for all treatments studied including any antiepileptic drug treatment, phenytoin treatment, antiepileptic drug treatment through discharge, number of antiepileptic drugs used, and treatment with pyridoxine (P < .001). These findings highlight the need for rigorous controlled outcome studies to determine optimal therapy for neonatal seizures and devise treatment standards.

Purpose: To describe the clinical characteristics of children with a first-time nonfebrile seizure in the setting of mild illness and to test the hypothesis that these seizures are associated with illness characterized by diarrhea., Methods: This retrospective cohort study was performed in a pediatric emergency department. Patients ages 6 months to 6 years who were evaluated with first-time seizures were eligible for inclusion. Subjects were divided into three groups on the basis of symptoms accompanying their seizure: febrile (temperature, >38.0 degrees C with seizure), unprovoked (no symptoms of illness), and nonfebrile illness (no fever at the time of seizure, but other symptoms of illness present)., Results: Of the 323 children with first-time seizures, 247 (76%) had febrile seizure, 37 (12%) had unprovoked seizures, and 39 (12%) had nonfebrile illness seizures. Children with nonfebrile illness seizures were more likely than children with febrile seizures to have diarrheal illnesses accompanying their seizure (44 vs. 16%; p=0.001). Frequency of cough, rhinorrhea, and rash did not differ significantly between children with febrile and nonfebrile illness seizures. Diagnostic testing for infectious etiologies was not performed frequently in either group., Conclusions: Nonfebrile illness seizures may represent a distinct group of seizures with unique epidemiology. Further study to define this seizure group better is warranted.

We showed that hypoxia is acutely epileptogenic in immature but not in adult rats. In the present study, we evaluated whether hypoxia results in an increase in long-term seizure susceptibility to flurothyl and whether this is associated with impaired performance on behavioral tests. We also determined whether these long-term outcomes are dependent on age at time of O2 deprivation. Long Evans hooded rats were rendered hypoxic on either postnatal day (P)5, P10, or P60. Sixty to 75 days after hypoxia, rats were tested for performance in water maze, open field, and handling tests and for seizure susceptibility to flurothyl. Hypoxia at P10 significantly increased seizure susceptibility to flurothyl, whereas hypoxia at P5 and P60 induced no long-term changes in seizure threshold. At P10, greater seizure severity during hypoxia and more prolonged exposure to hypoxia significantly increased long-term seizure susceptibility. This long-term change in seizure susceptibility appeared to be dissociated from any long-term neurobehavioral consequences, because only animals rendered hypoxic as adults (P60) had impaired behavioral performance. The results suggest that hypoxia-induced seizures can alter long-term seizure susceptibility and that this long-term effect is dependent on age and on severity of seizure activity at the time of previous hypoxia.
