RESUMEN
Migraine is the most common acute and recurrent headache syndrome in children. This condition has unique clinical characteristics in the pediatric population, that can evolve with age, and significantly impact a child's quality of life, affecting their education, socialization, and family life. The purpose of this review is to describe the varied clinical features of migraine seen in children, and discuss potential treatment options for pediatric migraine, including chronic migraine. In many patients a multifaceted approach involving lifestyle changes, treatment of comorbid conditions, and pharmacological treatments are needed for optimal headache control. WHAT THIS PAPER ADDS: Migraine presents as various phenotypes in children, sometimes evolving as the child ages. An expanded range of treatment options exists for the challenging chronic migraine patient.
MIGRAÑA CRÓNICA Y EPISÓDICA EN NIÑOS: La migraña es la cefalea sindromática más común y recurrente en niños. Esta condición tiene características clínicas únicas en la población pediátrica, que puede evolucionar con la edad, e impacta significativamente la calidad de vida del niño, afecta su educación, socialización y su vida familiar. El objetivo de esta revisión es describir la variabilidad de las características clínicas de la migraña observadas en el niño y se discute las potenciales opciones terapéuticas para la migraña pediátrica, incluyendo la migraña crónica. En muchos pacientes, un abordaje multifacético que incluya cambios en el estilo de vida, tratamiento de condiciones comórbidas, y, tratamiento farmacológico, son necesarias para un óptimo control de las cefaleas.
ENXAQUECA EPISÓDICA E CRÔNICA EM CRIANÇAS: Enxaqueca é a síndrome de dores de cabeça aguda e recorrente mais comum em crianças.

This paper describes the diagnostic criteria for "Vestibular Migraine of Childhood", "probable Vestibular Migraine of Childhood" and "Recurrent Vertigo of Childhood" as put forth by the Committee for the Classification of Vestibular Disorders of the Bárány Society (ICVD) and the Migraine Classification subgroup of the International Headache Society. Migraine plays an important role in some subgroups of children with recurrent vertigo. In this classification paper a spectrum of three disorders is described in which the migraine component varies from definite to possibly absent. These three disorders are: Vestibular Migraine of Childhood, probable Vestibular Migraine of Childhood and Recurrent Vertigo of Childhood. The criteria for Vestibular Migraine of Childhood (VMC) include (A) at least five episodes with vestibular symptoms of moderate or severe intensity, lasting between five minutes and 72 hours, (B) a current or past history of migraine with or without aura, and (C) at least half of episodes are associated with at least one migraine feature. Probable Vestibular Migraine of Childhood (probable VMC) is considered when at least three episodes with vestibular symptoms of moderate or severe intensity, lasting between five minutes and 72 hours, are accompanied by at least criterion B or C from the VMC criteria. Recurrent Vertigo of Childhood (RVC) is diagnosed in case of at least three episodes with vestibular symptoms of moderate or severe intensity, lasting between 1 minute and 72 hours, and none of the criteria B and C for VMC are applicable. For all disorders, the age of the individual needs to be below 18 years old. It is recommended that future research should particularly focus on RVC, in order to investigate and identify possible subtypes and its links or its absence thereof with migraine.

Unilateral chronic daily headache occurs in approximately 2% of adult patients, and often represents a trigeminal autonomic cephalalgia. We now describe the characteristics of 23 children who presented with a persistently unilateral chronic daily headache. The clinical features of our patients' headaches were primarily migrainous; however, the diagnosis of a trigeminal autonomic cephalalgia or a secondary headache disorder was frequently made.

New daily persistent headache (NDPH) is frequently seen in young patients with chronic daily headache. NDPH begins with a sudden onset, often associated with an infection or other physical stress. This headache syndrome is difficult to treat and may persist for years. This review discusses the epidemiology, comorbid symptoms, evaluation, and treatment of this disorder.

Chronic daily headache (CDH) occurs in 1-2% of children and adolescents. It can evolve from either episodic tension-type headache or episodic migraine, or can appear with no previous headache history. As with other primary headache disorders, treatment is based on the level of disability. There are children and adolescents who cope well, but there are others who are markedly disabled by their chronic headaches. As in adults, children and adolescents with CDH are at risk for medication overuse. CDH is a diagnosis of exclusion, based on a thorough history, normal physical examination, and negative neuroimaging findings. Along with the chronic headaches, children with this condition may have co-morbid sleep problems, autonomic dysfunction, anxiety, and/or depression. Principles of treatment include identifying migrainous components, stopping medication overuse, stressing normalcy, using rational pharmacotherapy, and addressing co-morbid conditions. Successful outcomes often involve identifying an appropriate headache preventative, reintegration into school, and family participation in resetting realistic expectations.

The human papillomavirus (HPV) vaccine is efficacious in preventing complications of human papillomavirus infection including cervical cancer. However, there have been case reports of adverse events occurring after vaccination, one being postural orthostatic tachycardia syndrome (POTS). This article reviews published data and other available information regarding the relationship between the human papillomavirus vaccine and POTS. Background information is provided regarding the human papillomavirus vaccine and the proposed post-vaccination adverse event POTS. Peer-reviewed literature, statements by government and medical advisory committees, and publicly available information published on this topic are examined. At this time, there is no conclusive evidence supporting a causal relationship between the human papillomavirus vaccine and POTS. Though a causal relationship has been postulated, it is of utmost importance to recognize that while temporal associations may be observed, conclusions of causality cannot be drawn from case reports and case series due to the small sample size and lack of control population.

Cluster headache is a primary headache disorder that can occur in children and adolescents, and is a member of the broader diagnostic group of trigeminal autonomic cephalalgias. It is characterized by repeated attacks typically lasting between 15 and 180 minutes of severe unilateral side-locked headache with cranial autonomic features. Acute treatment of the cluster attack can include the use of triptans or high-flow oxygen. Preventive measures typically start with the use of verapamil. The other trigeminal autonomic cephalalgias, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), and short-lasting unilateral neuralgiform headache with cranial autonomic features (SUNAA), have also been reported in children, and should be considered when the clinical presentation is at all unusual.

This study was performed to determine if there were a time of year that children were more likely to transition into a chronic daily headache. We retrospectively reviewed records of 103 patients with chronic migraine and 104 patients with new daily persistent headache. Of these, 56 chronic migraine and 92 new daily persistent headache patients were able to identify the specific month in which they began to experience daily headaches. Thirty-nine percent of new daily persistent headache patients had an onset of daily headache in either September or January, months traditionally associated with the start of the school semester in the United States. Only a single patient reported onset in May or June. Data for the transition from episodic to chronic migraine also showed higher rates in September and January, but did not reach statistical significance. These data demonstrate the higher rates of new daily persistent headache onset during school start months and question what factors may be responsible for this association.

The cause and treatment of functional movement disorders and nonepileptic spells in children is poorly understood, and an association with migraine has not previously been reported. We retrospectively reviewed children diagnosed with chronic or episodic migraine at our institution from 2006 to 2013 to determine the proportion with nonorganic movement disorders, their phenomenology, provoking factors, and natural history. Thirty-two patients were identified, representing 4.3% of patients with chronic migraine and 0.9% of patients with episodic migraine. Twenty-four of the 32 (75%) had chronic migraine, whereas 8 (25%) had episodic migraine. Nonepileptic spells was the most common phenomenon in both cohorts, followed by tremor and functional gait disorders. Severe migraine attacks preceded these movements in the majority of patients. With appropriate migraine therapy, significant reduction or resolution of these movements was reported. We conclude that nonorganic movement disorders are observed in pediatric migraine, are more prevalent among chronic migraineurs, and can resolve with improved pain control.

Chronic pain in children and adolescents can be difficult for a single provider to manage in a busy clinical setting. Part of this difficulty is that pediatric chronic pain not only impacts the child but also the families of these children. In this review article, we discuss etiology and pathophysiology of chronic pain, along with variables that impact the severity of chronic pain and functional loss. We review diagnosis and management of selected chronic pain conditions in pediatric patients, including headache, low back pain, hypermobility, chronic fatigue, postural orthostatic tachycardia syndrome, abdominal pain, fibromyalgia, and complex regional pain syndrome. For each condition, we create a road map that contains therapy prescriptions, exercise recommendations, and variables that may influence pain severity. Potential medications for these pain conditions and associated symptoms are reviewed. A multidisciplinary approach for managing children with these conditions, including pediatric pain rehabilitation programs, is emphasized. Lastly, we discuss psychological factors and interventions for pediatric chronic pain and potential complementary and alternative natural products and interventions.

Fragile X syndrome is a common inherited cause of mental retardation that results from the absence of the Fragile X Mental Retardation Protein (FMRP), an RNA binding protein thought to regulate translation of bound mRNAs, including its own. Previous studies in our laboratory have shown that FMRP expression increases in the barrel cortex of the rat after unilateral whisker stimulation, a model of experience dependent plasticity. This increase in protein is restricted to sub-cellular fractions enriched for synaptic or poly-ribosomal complexes. Here, we demonstrate that these increases are not accompanied by a change in FMR-1 mRNA levels and that they are blocked by the protein synthesis inhibitor cycloheximide in a dose dependent manner. Whisker stimulation dependent expression of FMRP is also abolished by pharmacological blockade of either NMDA receptors (MK-801, 0.25 mg/kg) or type I metabotropic glutamate receptors (AIDA, 5 mg/kg). In primary cortical neurons, activation of type I mGluRs leads to an increase in FMRP expression that is not effected by blockade of NMDA receptors. Taken together, these studies show that experience regulates FMRP production in vivo at the level of translation and supports a role for FMRP in metabotropic glutamate receptor mediated synaptic plasticity.

This study asked what incites the development of a new daily persistent headache in children. A total of 175 children with chronic daily headache were prospectively identified and observed by the author. Of these patients, 40 (23%) with a new daily persistent headache were identified. These patients had no significant prior headache history. Seventeen patients (43%) had the onset of their symptoms during an infection. Of these patients, over half had positive Epstein-Barr virus serology at the onset of symptoms. Nine patients (23%) manifested minor head injuries at the onset of their symptoms, yet had a normal examination and neuroimaging. Symptom onset was also associated with surgery (four patients) and high-altitude camping (one patient). In five patients, no specific etiologic factor could be identified. Four patients were initially identified as having idiopathic intracranial hypertension, yet their chronic headache persisted despite the normalization of their intracranial pressure. Similar findings were observed in episodic migraine patients who abruptly developed the onset of chronic migraine. In conclusion, the onset of new daily persistent headache in childhood is typically associated with a physiologic stress such as an infection, head trauma, or post-surgery.

Many teenagers who struggle with chronic fatigue have symptoms suggestive of autonomic dysfunction that may include lightheadedness, headaches, palpitations, nausea, and abdominal pain. Inadequate sleep habits and psychological conditions can contribute to fatigue, as can concurrent medical conditions. One type of autonomic dysfunction, postural orthostatic tachycardia syndrome, is increasingly being identified in adolescents with its constellation of fatigue, orthostatic intolerance, and excessive postural tachycardia (more than 40 beats/min). A family-based approach to care with support from a multidisciplinary team can diagnose, treat, educate, and encourage patients. Full recovery is possible with multi-faceted treatment. The daily treatment plan should consist of increased fluid and salt intake, aerobic exercise, and regular sleep and meal schedules; some medications can be helpful. Psychological support is critical and often includes biobehavioral strategies and cognitive-behavioral therapy to help with symptom management. More intensive recovery plans can be implemented when necessary.
