RESUMEN
BACKGROUND: Preschool age (i.e. children under six years of age) represents a red flag for requiring neuroimaging to exclude secondary potentially urgent intracranial conditions (PUIC) in patients with acute headache. We investigated the clinical characteristics of preschoolers with headache to identify the features associated with a greater risk of secondary "dangerous" headache. METHODS: We performed a multicenter exploratory retrospective study in Italy from January 2017 to December 2018. Preschoolers with new-onset non-traumatic headache admitted to emergency department were included and were subsequently divided into two groups: hospitalized and discharged. Among hospitalized patients, we investigated the characteristics linked to potentially urgent intracranial conditions. RESULTS: We included 1455 preschoolers with acute headache. Vomiting, ocular motility disorders, ataxia, presence of neurological symptoms and signs, torticollis and nocturnal awakening were significantly associated to hospitalization. Among the 95 hospitalized patients, 34 (2.3%) had potentially urgent intracranial conditions and more frequently they had neurological symptoms and signs, papilledema, ataxia, cranial nerves paralysis, nocturnal awakening and vomiting. Nevertheless, on multivariable logistic regression analysis, we found that only ataxia and vomiting were associated with potentially urgent intracranial conditions. CONCLUSION: Our study identified clinical features that should be carefully evaluated in the emergency department in order to obtain a prompt diagnosis and treatment of potentially urgent intracranial conditions. The prevalence of potentially urgent intracranial conditions was low in the emergency department, which may suggest that age under six should not be considered an important risk factor for malignant causes as previously thought.

Infantile regurgitation is one of the most common discomforts in the first months of life. Infantile colic and, in older children, functional dyspepsia have been linked to migraine. To date, this is the first study to investigate a possible association between infantile regurgitation and primary headaches in children. This is a case-control study of 195 children aged 6-17 years, with primary headache (migraine, or tension type headache) in 5 European paediatric hospitals. The control group is composed of 240 same-aged children attending with minor injuries during the same period - February 1st 2020 to December 1st 2020. A structured questionnaire identified a history of infantile regurgitation and other functional gastrointestinal disorders for case and control participants. The outcome was the difference in the prevalence of infantile regurgitation among children with or without a diagnosis of primary headache. The analysis showed a significant association between infantile regurgitation and migraine (OR = 1.88, CI 95 = 1.01-3.4, p = 0.04). No association was found between infantile regurgitation and tension type headache (p = 0.33). Subgroup analysis confirmed that the association was only significant for migraine without aura (OR = 2.3, CI 95 = 1.2-4.4, p = 0.01). In a further subgroup analysis, the presence of functional dyspepsia, irritable bowel syndrome and abdominal migraine was associated with migraine without aura. CONCLUSION: The presence of migraine among children aged 6-17 was associated with a history of infantile regurgitation. Additional longitudinal studies are required to confirm whether infantile regurgitation could be considered as a precursor of migraine. WHAT IS KNOWN: ⢠Children suffering from functional gastrointestinal disorders are more likely to be suffering from migraine and tension-type headache as well. ⢠Children suffering from primary headache are more likely to have had infantile colic in their first six month of life. WHAT IS NEW: ⢠It is the first study to find an association between migraine and infantile regurgitation in children. ⢠These findings could have an impact on the diagnosis and therapeutics of both migraine and infantile regurgitation.

BACKGROUND: There are no guidelines concerning the best approach to improving sleep, but it has been shown that it can benefit the affected children and their entire families. The aim of this review is to analyse the efficacy and safety of melatonin in treating pediatric insomnia and sleep disturbances. MAIN BODY: Sleep disturbances are highly prevalent in children and, without appropriate treatment, can become chronic and last for many years; however, distinguishing sleep disturbances from normal age-related changes can be a challenge for physicians and may delay treatment. Some published studies have shown that melatonin can be safe and effective not only in the case of primary sleep disorders, but also for sleep disorders associated with various neurological conditions. However, there is still uncertainty concerning dosing regimens and a lack of other data. The dose of melatonin should therefore be individualised on the basis of multiple factors, including the severity and type of sleep problem and the associated neurological pathology. CONCLUSIONS: Melatonin can be safe and effective in treating both primary sleep disorders and the sleep disorders associated with various neurological conditions. However, there is a need for further studies aimed at identifying the sleep disordered infants and children who will benefit most from melatonin treatment, and determining appropriate doses based on the severity and type of disorder.

INTRODUCTION: Among neonates and infants <3 months of age with fever without a source (FWS), 5% to 15% of cases are patients with fever caused by a serious bacterial infection (SBI). To favour the differentiation between low- and high-risk infants, several algorithms based on analytical and clinical parameters have been developed. The aim of this review is to describe the management of young infants with FWS and to discuss the impact of recent knowledge regarding FWS management on clinical practice. MATERIALS AND METHODS: PubMed was used to search for all of the studies published over the last 35 years using the keywords: "fever without source" or "fever of unknown origin" or "meningitis" or "sepsis" or "urinary tract infection" and "neonate" or "newborn" or "infant <90 days of life" or "infant <3 months". RESULTS AND DISCUSSION: The selection of neonates and young infants who are <3 months old with FWS who are at risk for SBI remains a problem without a definitive solution. The old Rochester criteria remain effective for identifying young infants between 29 and 60 days old who do not have severe bacterial infections (SBIs). However, the addition of laboratory tests such as C-reactive protein (CRP) and procalcitonin (PCT) can significantly improve the identification of children with SBI. The approach in evaluating neonates is significantly more complicated, as their risk of SBIs, including bacteremia and meningitis, remains relevant and none of the suggested approaches can reduce the risk of dramatic mistakes. In both groups, the best antibiotic must be carefully selected considering the clinical findings, the laboratory data, the changing epidemiology, and increasing antibiotic resistance of the most common infectious bacteria.

BACKGROUND: Cyclic Vomiting Syndrome (CVS) is a rare functional gastrointestinal disorder, which has a considerable burden on quality of life of both children and their family. Aim of the study was to evaluate the diagnostic modalities and therapeutic approach to CVS among Italian tertiary care centers and the differences according to subspecialties, as well as to explore whether potential predictive factors associated with either a poor outcome or a response to a specific treatment. METHODS: Cross-sectional multicenter web-based survey involving members of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) and Italian Society of Pediatric Neurology (SINP). RESULTS: A total of 67 responses were received and analyzed. Most of the respondent units cared for less than 20 patients. More than half of the patients were referred after 3 to 5 episodes, and a quarter after 5 attacks. We report different diagnostic approaches among Italian clinicians, which was particularly evident when comparing gastroenterologists and neurologists. Moreover, our survey demonstrated a predilection of certain drugs during emetic phase according to specific clinic, which reflects the cultural background of physicians. CONCLUSION: In conclusion, our survey highlights poor consensus amongst clinicians in our country in the diagnosis and the management of children with CVS, raising the need for a national consensus guideline in order to standardize the practice.

OBJECTIVES: Acute nystagmus (AN) is an uncommon neurologic sign in children presenting to pediatric emergency departments. We described the epidemiology, clinical features, and underlying causes of AN in a large cohort of children, aiming at identifying features associated with higher risk of severe underlying urgent conditions (UCs). METHODS: Clinical records of all patients aged 0 to 18 years presenting for AN to the pediatric emergency departments of 9 Italian hospitals in an 8-year period were retrospectively reviewed. Clinical and demographic features and the underlying causes were analyzed. A logistic regression model was applied to detect predictive variables associated with a higher risk of UCs. RESULTS: A total of 206 patients with AN were included (male-to-female ratio: 1.01; mean age: 8 years 11 months). The most frequently associated symptoms were headache (43.2%) and vertigo (42.2%). Ataxia (17.5%) and strabismus (13.1%) were the most common neurologic signs. Migraine (25.7%) and vestibular disorders (14.1%) were the most common causes of AN. Idiopathic infantile nystagmus was the most common cause in infants <1 year of age. UCs accounted for 18.9% of all cases, mostly represented by brain tumors (8.3%). Accordant with the logistic model, cranial nerve deficits, ataxia, or strabismus were strongly associated with an underlying UC. Presence of vertigo or attribution of a nonurgent triage code was associated with a reduced risk of UCs. CONCLUSIONS: AN should be considered an alarming finding in children given the risk of severe UCs. Cranial nerve palsy, ataxia, and strabismus should be considered red flags during the assessment of a child with AN.

After more than a century from its discovery, valproic acid (VPA) still represents one of the most efficient antiepileptic drugs (AEDs). Pre and post-synaptic effects of VPA depend on a very broad spectrum of actions, including the regulation of ionic currents and the facilitation of GABAergic over glutamatergic transmission. As a result, VPA indirectly modulates neurotransmitter release and strengthens the threshold for seizure activity. However, even though participating to the anticonvulsant action, such mechanisms seem to have minor impact on epileptogenesis. Nonetheless, VPA has been reported to exert anti-epileptogenic effects. Epigenetic mechanisms, including histone deacetylases (HDACs), BDNF and GDNF modulation are pivotal to orientate neurons toward a neuroprotective status and promote dendritic spines organization. From such broad spectrum of actions comes constantly enlarging indications for VPA. It represents a drug of choice in child and adult with epilepsy, with either general or focal seizures, and is a consistent and safe IV option in generalized convulsive status epilepticus. Moreover, since VPA modulates DNA transcription through HDACs, recent evidences point to its use as an anti-nociceptive in migraine prophylaxis, and, even more interestingly, as a positive modulator of chemotherapy in cancer treatment. Furthermore, VPA-induced neuroprotection is under investigation for benefit in stroke and traumatic brain injury. Hence, VPA has still got its place in epilepsy, and yet deserves attention for its use far beyond neurological diseases. In this review, we aim to highlight, with a translational intent, the molecular basis and the clinical indications of VPA.

West syndrome (WS), also known as infantile spasms, occurs in infancy with a peak between 4 and 7 months. Spasms, neurodevelopmental regression and hypsarrhythmia on electroencephalogram (EEG) basically define WS. The International League Against Epilepsy commission classifies the aetiologies of WS into genetic, structural, metabolic and unknown. Early diagnosis and a shorter lag time to treatment are essential for the overall outcome of WS patients. These goals are feasible with the addition of brain magnetic resonance imaging (MRI) and genetic and metabolic testing. The present work analysed the medical literature on WS and reports the principal therapeutic protocols of its management. Adrenocorticotropic hormone (ACTH), vigabatrin (VGB) and corticosteroids are the first-line treatments for WS. There is no unique therapeutic protocol for ACTH, but most of the evidence suggests that low doses are as effective as high doses for short-term treatment, which is generally 2 weeks followed by dose tapering. VGB is generally administered at doses from 50 to 150 mg/kg/day, but its related retinal toxicity, which occurs in 21-34% of infants, is most frequently observed when treatment periods last longer than 6 months. Among corticosteroids, a treatment of 14 days of oral prednisolone (40-60 mg/day) has been considered effective and well tolerated. Considering that an early diagnosis and a shorter lag time to treatment are essential for successful outcomes in these patients, further studies on efficacy of the different therapeutic approaches with evaluation of final outcome after cessation of therapy are needed.

Mycoplasma pneumoniae is mainly recognized as a respiratory pathogen, although it is associated with the development of several extra-respiratory conditions in up to 25% of the cases. Diseases affecting the nervous system, both the peripheral (PNS) and the central nervous system (CNS), are the most severe. In some cases, particularly those that involve the CNS, M. pneumoniae-related neuropathies can lead to death or to persistent neurologic problems with a significant impact on health and a non-marginal reduction in the quality of life of the patients. However, the pathogenesis of most of the M. pneumoniae-related neuropathies remains undefined. The main aim of this paper is to discuss what is presently known regarding the pathogenesis and treatment of the most common neurologic disorders associated with M. pneumoniae infection. Unfortunately, the lack of knowledge of the true pathogenesis of most of the cases of M. pneumoniae-mediated neurological diseases explains why treatment is not precisely defined. However, antibiotic treatment with drugs that are active against M. pneumoniae and able to pass the blood-brain barrier is recommended, even though the best drug, dosage, and duration of therapy have not been established. Sporadic clinical reports seem to indicate that because immunity plays a relevant role in the severity of the condition and outcome, attempts to reduce the immune response can be useful. However, further studies are needed before the problem of the best therapy for M. pneumoniae-mediated neurological diseases can be efficiently solved.
RESUMEN
BACKGROUND: Recent studies have shown a possible coexistence of absence seizures with other forms of epilepsy. The purpose of this study was to ascertain the possible contemporary or subsequent presence of childhood absence epilepsy (CAE) and benign epilepsy with centro-temporal spikes (BECTS) in pediatric epileptic patients. DATA SOURCES: A PubMed systematic search indexed for MEDLINE, PubMed and EMBASE was undertaken to identify studies in children including articles written between 1996 and 2015. Retrospective studies, meta-analysis and case reports were included. The list of references of all the relevant articles was also studied. The date of our last search was December 2015. RESULTS: Review of the literature revealed 19 cases, 8 females and 11 males, reporting a consecutive or contemporary coexistence of CAE and BECTS within the same patients. Patient's age ranged between 4 and 12 years. Three out of 19 patients presented concomitant features of both syndromes, whereas 16 patients experienced the two syndromes at different times. CONCLUSIONS: BECTS and CAE may be pathophysiologically related, and the two epileptic phenotypes may indicate a neurobiological continuum. Further studies are needed to elucidate a probable genetic or functional link between partial and primarily generalized electro-clinical patterns in idiopathic childhood epilepsies.

AIM: Childhood absence epilepsy (CAE) and benign childhood epilepsy with centrotemporal spikes (BECTS) are the most common forms of childhood epilepsy. Recent studies in animal models suggest that the two phenotypes may represent a neurobiological continuum. Although the coexistence of CAE and BECTS has been reported, this issue remains controversial. The purpose of this study was to analyse the electro-clinical characteristics of a group of children with contemporary or subsequent features of absence seizures and focal seizures consistent with BECTS. MATERIAL AND METHODS: A systematic record review from 8 epilepsy centres was used to identify 11 subjects, 5 females and 6 males, with electro-clinical documented consecutive or contemporary coexistence of CAE and BECTS. RESULTS: Patient's age ranged between 7.8 and 17.3 years. Four out of 11 patients presented concomitant features of both syndromes, whereas the remaining 7 experienced the two syndromes at different times. CONCLUSIONS: Although CAE and BECTS are clearly defined syndromes and considered very different in terms of their pathophysiology, they share some features (such as similar age of onset, overall good prognosis), and can occur in the same patient. The long term prognosis of these patients seems to be good with an excellent response to anticonvulsant therapy.

BACKGROUND: Epilepsy associated with Prader-Willi syndrome (PWS) represents an early and important complication, often not clearly reported and described in the literature. Consequently, there are controversial data about the clinical characteristics of epilepsy and electroencephalographic (EEG) abnormalities found in these patients. DATA SOURCES: Based on recent original publications, we have reviewed the different types of seizures and EEG findings in PWS patients, the response to antiepileptic treatment, and the prognosis of epilepsy. RESULTS: The frequency of epilepsy in PWS patients ranges from 4% to 26%. The types of seizure include generalized tonic-clonic seizures, complex partial seizures, atypical absence, staring spells, and myoclonic, tonic and hemiclonic seizures, but the most frequent type is focal epilepsy. Status epilepticus has never been reported. EEG abnormalities are not typical but variable in different patients. However, generalized and focal discharges are the most frequently reported findings. There is no evidence of relationship between the course of epilepsy and frequency, morphology and spread of EEG discharges. However, epilepsy in PWS patients is usually responsive to antiepileptic monotherapy with rapid seizure control and a good outcome. CONCLUSIONS: The frequency of epilepsy is higher in PWS patients than in general populations and this complication can be a challenge for the clinicians of these patients. Prospective studies are needed to confirm the good long-term prognosis.
