RESUMO
OBJECTIVE: We conducted a descriptive study of symptomatic epilepsy by age at onset in a cohort of patients who were followed up at a neuropaediatric department of a reference hospital over a 3-year period PATIENTS AND METHODS: We included all children with epilepsy who were followed up from January 1, 2008 to December 31, 2010 RESULTS: Of the 4595 children seen during the study period, 605 (13.17%) were diagnosed with epilepsy; 277 (45.79%) of these had symptomatic epilepsy. Symptomatic epilepsy accounted for 67.72% and 61.39% of all epilepsies starting before one year of age, or between the ages of one and 3, respectively. The aetiologies of symptomatic epilepsy in our sample were: prenatal encephalopathies (24.46% of all epileptic patients), perinatal encephalopathies (9.26%), post-natal encephalopathies (3.14%), metabolic and degenerative encephalopathies (1.98%), mesial temporal sclerosis (1.32%), neurocutaneous syndromes (2.64%), vascular malformations (0.17%), cavernomas (0.17%), and intracranial tumours (2.48%). In some aetiologies, seizures begin before the age of one; these include Down syndrome, genetic lissencephaly, congenital cytomegalovirus infection, hypoxic-ischaemic encephalopathy, metabolic encephalopathies, and tuberous sclerosis. CONCLUSIONS: The lack of a universally accepted classification of epileptic syndromes makes it difficult to compare series from different studies. We suggest that all epilepsies are symptomatic because they have a cause, whether genetic or acquired. The age of onset may point to specific aetiologies. Classifying epilepsy by aetiology might be a useful approach. We could establish 2 groups: a large group including epileptic syndromes with known aetiologies or associated with genetic syndromes which are very likely to cause epilepsy, and another group including epileptic syndromes with no known cause. Thanks to the advances in neuroimaging and genetics, the latter group is expected to become increasingly smaller.

INTRODUCTION: Global developmental delay (GDD) and intellectual disability (ID) are common reasons for consultation in paediatric neurology. Results from aetiological evaluations of children with GDD/ID vary greatly, and consequently, there is no universal consensus regarding which studies should be performed. MATERIAL AND METHOD: We review our experience with determining aetiological diagnoses for children with GDD/ID who were monitored by the paediatric neurology unit over the 5-year period between 2006 and 2010. RESULTS: During the study period, 995 children with GDD/ID were monitored. An aetiological diagnosis was established for 309 patients (31%), but not in 686 (69%), despite completing numerous tests. A genetic cause was identified in 142 cases (46% of the total aetiologies established), broken down as 118 cases of genetic encephalopathy and 24 of metabolic hereditary diseases. Our data seem to indicate that diagnosis is easier when GDD/ID is associated with cerebral palsy, epilepsy, infantile spasms/West syndrome, or visual deficit, but more difficult in cases of autism spectrum disorders. Genetic studies provide an increasing number of aetiological diagnoses, and they are also becoming the first step in diagnostic studies. Array CGH (microarray-based comparative genomic hybridisation) is the genetic test with the highest diagnostic yield in children with unexplained GDD/ID. DISCUSSION: The cost-effectiveness of complementary studies seems to be low if there are no clinically suspected entities. However, even in the absence of treatment, aetiological diagnosis is always important in order to provide genetic counselling and possible prenatal diagnosis, resolve family (and doctors') queries, and halt further diagnostic studies.

OBJECTIVE: The purpose of this study is to determine the profile of the demand for paediatric neurology care in a Spanish tertiary hospital over the past 20 years. METHOD: We studied epidemiological data, reasons for consultation, diagnoses and complementary tests from all patients examined by our Paediatric Neurology Unit in its 20 years of service (from May 1990 to March 2010). We also reviewed data from patients whose first visit took place within the last five years (2005-2010) and compared them to data obtained from a prior study carried out in this Unit from 1990 to 1995. To compare the first 5 years (group 1) with the last 5 years (group 2), we calculated confidence intervals, P<.05, for the frequency distribution (%) in each category. RESULTS: Main reasons for consultation and principal diagnoses for the 12726 patients evaluated in the 20-year period, as well as results from group 1 (2046 patients) and group 2 (4488 patients) corresponding to first and the last 5 years of activity respectively, are presented with their confidence intervals in a series of tables. CONCLUSIONS: Variations in the reasons for consultation, diagnoses and complementary tests over time reflect changes determined by medical, scientific and social progress, and organisational changes specific to each hospital. This explains the difficulty of comparing different patient series studied consecutively, which are even more pronounced between different hospitals.

INTRODUCTION: We examine those prenatal encephalopathies with clinical or neuroimaging data of encephalopathy before the birth. They affect a significant number of children seen by paediatric neurologists. They can be of disruptive origin (due to vascular problems, drugs, toxins or congenital infections), and genetically determined. We include cases of autism spectrum disorder and mental retardation with no history of perinatal of postnatal damages. MATERIAL AND METHODS: We analysed our 19 year neuro-paediatric data base in search of prenatal encephalopathies and their diagnostic origin. We also analyse the studies made in the cases with a diagnosis of unknown origin. RESULTS: The 19 year period of study in the data base included 11,910 children, and 1596 (13.5%) were considered as prenatal encephalopathies; 1307 children (81.4%) had a diagnosis of unknown origin, despite many investigations being done in a large number of them. DISCUSSION: Most of the children included in this study suffer a rare disease, and whether they are identified or not, they increasingly require an early diagnosis. Peroxisomal, mitochondrial, lysosomal diseases, carbohydrate glycosylation deficiency syndrome and other inborn error of metabolism, congenital infections and genetic encephalopathies, can be clinically indistinguishable in early life and require specific studies to identify them. Early diagnosis requires strategies using step-wise systematic studies, giving priority to those diseases that could be treated, and in many cases using an individualised approach. We believe that the potential benefits of early diagnosis, including savings on further studies, genetic counselling and prenatal diagnosis, overcome the financial costs.

INTRODUCTION AND OBJECTIVE: In this article, we present our experience on optic neuritis (ON) and provide a diagnostic/therapeutic protocol, intended to rule out other aetiologies (particularly infection), and a fact sheet for parents. MATERIAL AND METHODS: We conducted a descriptive, retrospective study of patients with ON over a 27-year period (1990-2017). A review of the available scientific evidence was performed in order to draft the protocol and fact sheet. RESULTS: Our neuropaediatrics department has assessed 20,744 patients in the last 27 years, of whom 14 were diagnosed with ON: 8 had isolated ON, 1 had multiple sclerosis (MS), 1 had clinically isolated syndrome (CIS), 3 had acute disseminated encephalomyelitis, and 1 had isolated ON and a history of acute disseminated encephalomyelitis one year previously. Patients' age range was 4-13 years; 50% were boys. Eight patients were aged over 10: 7 had isolated ON and 1 had MS. Nine patients had bilateral ON, and 3 had retrobulbar ON. MRI results were normal in 7 patients and showed involvement of the optic nerve only in 2 patients and optic nerve involvement + central nervous system demyelination in 5. Thirteen patients received corticosteroids. One patient had been vaccinated against meningococcus-C the previous month. Progression was favourable, except in the patient with MS. A management protocol and fact sheet are provided. CONCLUSIONS: ON usually has a favourable clinical course. In children aged older than 10 years with risk factors for MS or optic neuromyelitis (hyperintensity on brain MRI, oligoclonal bands, anti-NMO antibody positivity, ON recurrence), the initiation of immunomodulatory treatment should be agreed with the neurology department. The protocol is useful for diagnostic decision-making, follow-up, and treatment of this rare disease with potentially major repercussions. The use of protocols and fact sheets is important.

INTRODUCTION: There are transient intracranial hypertension cases, recognizable by bulging fontanelle in infants and by papilloedema in children. We present our experience in benign intracranial hypertension (BIH) cases, excluding traumatic brain injuries, encephalitis and meningitis. RESULTS: Among the entire neuropaediatric database, with 10,720 children in 18 years, 31 cases had the diagnosis of BIH. Sixteen aged between 2.3 and 8.9 months (75% males), all of them with transient bulging fontanelle, and 15 aged between 4.4 and 13.7 years (73.3% females), all of them with papilloedema which was subsequently resolved. A total of 75% of infants had recently finished corticosteroid treatment for bronchitis. In the older children, there was 1 case associated with excessive vitamin A intake and 1 mastoiditis. Transfontanelle ultrasonography or CT was performed on all infants and CT or MRI in every child. Lumbar puncture was also performed on 7 infants and on 13 children. Infants developed favourably in a few days, and children did so between 1 week and 5 months, some with treatment. DISCUSSION: BIH usually has a favourable outcome, although it may take longer in children than in infants, but it can have serious visual repercussions, even blindness, so ophthalmological control is necessary. It is normally diagnosed by exclusion of other intracranial hypertension causes. MRI and lumbar puncture must be done on all children or infants who do not progress favourably. Acetazolamide and furosemide, corticosteroids, repeated lumbar punctures and optic nerve sheath fenestration should be considered in those who do not progress well.

INTRODUCTION: Type I Chiari malformation consists on the caudal displacement of cerebellar tonsils through the foramen magnum. It is often asymptomatic, although it may display symptoms as a result of cerebellum, brainstem, high cervical spinal cord or the lower cranial nerve, involvement. OBJECTIVE: We report our experience over the last 16 years. We have identified 16 patients with type I Chiari malformation. Only 2 cases showed common type I Chiari symptoms and just one had respiratory disorder as the first clinical sign. CLINICAL CASE: A 15 year old girl presented with a 5 years' history of chronic daily cough aggravated by exercise. Snoring and sleep apnea had been noted by her mother for 1 year. The girl eventually suffered from migraine and diurnal hypersomnolence. The physical and neurological examination was normal with the only exception being the absence of bilateral nauseous reflex. A nocturnal polysomnography study demonstrated a pseudoperiodic pattern with apnea pauses associated to cycles of deep breathing, resulting in severe gasometric repercussion and bradycardia. Magnetic resonance imaging of the brain showed Chiari I malformation. Non-invasive mechanical ventilation treatment significantly improved the clinical symptoms and gasometric analysis. DISCUSSION: Surgical posterior fossa decompression is discussed. Early decompression before appearance of irreversible neurological damage is recommended. It is associated with a significant reduction in the number of central apneas and sleep arousals. Surgical intervention is recommended in symptomatic patients and in cases of radiographic Chiari malformation or syrinx progression.

INTRODUCTION: Botulinum toxin type A (BTA) is a bacterial endotoxin, whose therapeutic use has had a dramatic impact on different neurological disorders, such as dystonia and spasticity. AIM: To analyze and summarize different questions about the use of BTA in our clinical practice. DEVELOPMENT: A group of experts in neurology developed a list of topics related with the use of BTA. Two groups were considered: neuropharmacology and dystonia. A literature search at PubMed, mainly for English language articles published up to June 2016 was performed. The manuscript was structured as a questionnaire that includes those questions that, according to the panel opinion, could generate more controversy or doubt. The initial draft was reviewed by the expert panel members to allow modifications, and after subsequent revisions for achieving the highest degree of consensus, the final text was then validated. Different questions about diverse aspects of neuropharmacology, such as mechanism of action, bioequivalence of the different preparations, immunogenicity, etc. were included. Regarding dystonia, the document included questions about methods of evaluation, cervical dystonia, blepharospasm, etc. CONCLUSION: This review does not pretend to be a guide, but rather a tool for continuous training of residents and specialists in neurology, about different specific areas of the management of BTA.

INTRODUCTION: As result of our aim to improve the quality standard of our emergency system, work has been carried out in relation to the development and monitorization of effective clinical protocols in the department of paediatric practice. PATIENTS AND METHODS: An evidence based review approach was taken to design a clinical protocol about Bell's palsy condition for the paediatric emergency department. Previous protocol approved in March 2003 was reviewed accordingly with the new designed protocol's quality standards. The Bell's palsy cases reported since March 2003 until June 2006 to paediatric emergency department were analyzed. RESULTS: A total of 27 patients affected by Bell's palsy were reported to the hospital's emergency department. Facial expression was described in 85.19% of the cases. Cranial nerves normal function was reported in 77.78%. Fundoscopic examination was described in 77.78% and otoscopic findings in 44.44%; the absence of herpes vesicles was analyzed only in 11.11%. All patients received steroid therapy (prednisone) and the treatment resulted in the complete recovery. The mean time to resolution was 58.6 days. CONCLUSIONS: In order to improve hospital's quality standards, clinical protocols should be designed and verified regularly to ensure the proper performance. Medical auditing also contributes to improve effectiveness in health attendance.

AIM: To determine the characteristics of the demand for health care in hereditary-metabolic diseases in a Spanish tertiary care hospital. PATIENTS AND METHODS: We conducted a retrospective descriptive study involving a review of the epidemiological data, reasons for visiting, diagnoses and complementary studies of the patients treated by a metabolic disease unit over a period of 6 years and 11 months. RESULTS: Altogether 1012 patients were evaluated. There was a predominance of males (52%) and of patients under the age of 1 year (42.09%). 71.44% of them were under 6 years old. Approximately half of the patients (50.3%) came from hospitals (wards, outpatients, neonatology, emergency department, neuropaediatrics and intensive care), followed by the neonatal screening programme (20.36%) and primary care (14.82%). The most frequent reasons for visiting and diagnoses can be seen in their respective tables. CONCLUSIONS: The study of the demand for health care in hereditary-metabolic diseases is useful as a means to detect needs in their field and to try to adapt care to meet them. Medical, scientific and social progress makes it necessary to have an expert in metabolism present in reference clinical units. As members of multidisciplinary teams alongside other specialists, they will contribute towards accomplishing a suitable presumptive diagnosis, diagnosis, management and follow-up. It is necessary to keep them constantly up-to-date and ensure adequate training of new experts in metabolism, since this is the best way to deliver optimal care for those with metabolic illnesses, which are usually rare diseases.

INTRODUCTION: Spasticity is a medical problem with a high incidence that significantly impact on the quality of life of patients and their families. AIM: To analyze and to answer different questions about the use of botulinum toxin type A (BTA) in our clinical practice. DEVELOPMENT: A group of experts in neurology develop a list of topics related with the use of BTA. Two big groups were considered: spasticity in adults and in children with cerebral palsy. A literature search at PubMed for English, French, and Spanish language articles published up to June 2016 was performed. The manuscript was structured as a questionnaire that includes those questions that, according to the panel opinion, could generate more controversy or doubt. The initial draft was reviewed by the expert panel members to allow for modifications, and after subsequent revisions for achieving the highest degree of consensus, the final text was then validated. Different questions about diverse aspects of spasticity in adults, such as methods for evaluating spasticity, infiltration techniques, doses, number of infiltration points, etc. Regarding spasticity in children with cerebral palsy, the document included questions about minimum age of infiltration, methods of analgesia, etc. CONCLUSIONS: This review is a tool for continuous training for neurologist and rehabilitation specialist and residents of both specialties, about different specific areas of the management of BTA.

INTRODUCTION: Benign paroxysmal torticollis (BPT) is characterised by recurring episodes of lateral bending of the neck, occasionally accompanied by vegetative symptoms, ataxia or an abnormal position of the trunk, with a tendency to disappear spontaneously after some months or years, and with no alterations between episodes. AIM: To analyse the clinical and developmental characteristics of the cases evaluated by the Neuropaediatric Service at our hospital that were classified as BPT. PATIENTS AND METHODS: We reviewed the history of the patients with BPT included in the Neuropaediatric Service database over a 15-year period. Patients who were not following any kind of control were contacted by telephone. RESULTS: We found 13 BPT patients with typical criteria, and 4 others with possible BPT (p-BPT), because they had had an isolated episode of torticollis. Neuroimaging was carried out in nine children (69.2%) from the BPT group: this included only transfontanellar ultrasound recording (TF USR) in six cases, TF USR and computerised axial tomography (CAT) in one child, only a CAT scan in one case, and CAT and magnetic resonance imaging in another. Neuroimaging was performed in all the cases of p-BPT: CAT scans were carried out in two cases and TF USR was used in two others. CONCLUSIONS: Atypical cases can be excluded by establishing a diagnosis of BPT with strict criteria. Since no biological markers are available, the diagnosis must be based on the clinical pattern and course and, in some cases, complementary examinations have to be performed to preclude other pathologies. When a child is diagnosed with BPT, the family needs to be reassured and told that it is a benign process with a tendency to disappear spontaneously.

AIM: A descriptive study of non-symptomatic epilepsy (idiopathic and cryptogenic), according to age at onset, monitored at a Neuropediatric Section of regional reference over a period of three years. PATIENTS AND METHODS: A review of neuropediatric database medical records of children with non-symptomatic epilepsy supervised from Jan 1, 2008 till December 31, 2010. RESULTS: Of the 4595 children attended during the period, 605 were diagnosed with epilepsy (13.17%): 156 (25.79%) idiopathic epilepsies and 172 (28.43%) cryptogenic epilepsies. The average age at onset of the total was 4.78 years: 6.31 years in idiopathic epilepsies and 5.43 years in cryptogenic epilepsies. 26.12% of all the epilepsies began in the first year of life. Idiopathic epilepsy predominates in the startup group of 6-10 years and cryptogenic epilepsy in 3-6 years. Absence epilepsy and benign childhood epilepsy with centro-temporal spikes are the idiopathic epileptic syndromes most prevalent. CONCLUSIONS: Many differences exist among published epidemiological data on childhood epilepsy due to the difficulty of a syndromic diagnosis in children, caused by clinical and electroencephalographic variability. The absence of a universally accepted classification of epileptic syndromes makes it difficult to compare publications. All epilepsies are symptomatic as they have a cause, whether it be genetic or acquired. A useful classification would be etiological, with two groups: one large with established etiology or very likely genetic syndromes and another with no established cause. The age at onset indicates specific etiologies.
TITLE: Estudio descriptivo de las epilepsias no sintomaticas segun la edad de inicio en una unidad de neuropediatria de referencia regional.Objetivo. Estudio descriptivo de las epilepsias no sintomaticas (idiopaticas y criptogenicas), segun la edad de inicio, controladas en una unidad de neuropediatria de referencia regional durante tres años. Pacientes y metodos. Revision de historias de niños con epilepsia no sintomatica de la base de datos de neuropediatria controlados del 1 de enero de 2008 al 31 de diciembre de 2010. Resultados. De 4.595 niños atendidos en el periodo, se diagnosticaron de epilepsia 605 (13,17%), de las cuales 156 (25,79%) fueron idiopaticas, y 172 (28,43%), criptogenicas. La edad media de inicio del total fue de 4,78 años; 6,31 años en las idiopaticas y 5,43 años en las criptogenicas. El 26,12% del total de epilepsias se inicio en el primer año. Las epilepsias idiopaticas predominan en el grupo de inicio de 6-10 años, y las criptogenicas, en el de 3-6 años. La epilepsia de ausencias y la epilepsia benigna de la infancia con paroxismos centrotemporales son los sindromes epilepticos idiopaticos mas prevalentes. Conclusiones. Existen muchas diferencias de datos epidemiologicos publicados sobre epilepsia infantil por la dificultad que entraña un diagnostico sindromico en la edad pediatrica, debido a la variabilidad clinica y electroencefalografica. La ausencia de una clasificacion universalmente aceptada de los sindromes epilepticos dificulta comparaciones entre series. Todas las epilepsias son sintomaticas, puesto que tienen causa, sea genetica o adquirida. Una clasificacion util es la etiologica, con dos grupos: un gran grupo con las etiologias establecidas o sindromes geneticos muy probables y otro de casos sin causa establecida. La edad de inicio orienta a determinadas etiologias.

BACKGROUND: Prematurity and low birth weight are known risk factors for cognitive and developmental impairments, and school failure. Visual perceptual and visual motor skills seem to be among the most affected cognitive domains in these children. AIMS: To assess the influence of prematurity and low birth weight in visual cognitive skills and school performance. METHODS: We performed a prospective cohort study, which included 80 boys and girls in an age range from 5 to 13. Subjects were grouped by gestational age at birth (preterm, <37 weeks; term, 37-42 weeks) and birth weight (small for gestational age (SGA), <10th centile; appropriate weight for gestational age (AGA), ≥10th centile). Each child underwent full ophthalmologic assessment and standardized testing of visual cognitive abilities (Test of Visual Perceptual Skills and Test of Visual Analysis Skills). Parents completed a questionnaire on school performance in children. RESULTS: Figure-ground skill and visual motor integration were significantly decreased in the preterm birth group, compared with term control subjects (figure-ground: 45.7 vs 66.5, p=0.012; visual motor integration, TVAS: (9.9 vs 11.8, p=0.018), while outcomes of visual memory (29.0 vs 47.7, p=0.012), form constancy (33.3 vs 52.8, p=0.019), figure-ground (37.4 vs 65.6, p=0.001), and visual closure (43.7 vs 62.6 p=0.016) testing were lower in the SGA (vs AGA) group. Visual cognitive difficulties corresponded with worse performance in mathematics (r=0.414, p=0.004) and reading (r=0.343, p=0.018). CONCLUSION: Specific patterns of visual perceptual and visual motor deficits are displayed by children born preterm or SGA, which hinder mathematics and reading performance.

INTRODUCTION: Shaken baby syndrome (SBS) is a form of physical abuse that includes the presence of a subdural or subarachnoid haematoma or diffuse cerebral oedema, retinal haemorrhages and, in general, absence of other physical signs of traumatic injury. Osteogenesis imperfecta (OI) is a genetic disorder affecting the synthesis of type I collagen that leads to brittle bones with frequently occurring fractures, with presenting clinical symptoms taking a variety of forms. A differential diagnosis allowing it to be distinguished from physical abuse is known, due to the existence of bone fractures with no known traumatic injuries, but we do not understand the link between OI and SBS. CASE REPORT: We describe the case of an infant who, at the age of 3 months, suffered symptoms of acute encephalopathy with convulsions, subdural haematoma and retinal haemorrhages compatible with SBS, as well as bilateral rib fractures. The skeletal series of X-rays revealed alterations in bone structure and texture, which led to a diagnosis of OI that was confirmed by a study of the collagen in skin fibroblasts. CONCLUSIONS: The suspected existence of SBS is unpleasant both for the health care professional and for the patient's relatives. The existence of rib fractures in an obvious case of shaken baby syndrome suggested malicious abuse; however, the parents' attitude and the existence of OI made us think that no harm was intended. Shaking could have been secondary to bouts of crying due to microfissures related to the OI. The differential diagnosis of processes that can be mistaken for shaken baby or from favourable or predisposing medical factors must be taken into consideration.

INTRODUCTION: 10-15% of asymptomatic congenital infections by cytomegalovirus (CMV) in the neonatal period develop persistent problems with varying degrees of severity, fundamentally involving neurological disorders, neurosensory hypoacusis and hypovision, which appear from the age of 6-9 months onwards, when a diagnosis is no longer possible. The PCR (polymerase chain reaction) technique can detect DNA of CMV in blood samples on filter paper used for screening hypothyroidism and metabolic pathologies that were kept from the neonatal period. CASE REPORT: A child aged 3 years and 8 months with delayed intrauterine growth, autism, mental retardation, microcephalus and neurosensory hypoacusis; periventricular calcifications, leukoencephalopathy and bilateral malformation of the temporal lobe; and a diagnosis of congenital CMV confirmed by detection of DNA by PCR in the blood sample on filter paper saved from the neonatal period. CONCLUSIONS: The retrospective study of congenital infection by CMV should be considered when faced with severity and varying association of delayed intrauterine growth, microcephalus, neurosensory hypoacusis, chorioretinitis, mental retardation, autism or other behavioural disorders, intracranial calcifications, encephaloclastic alterations, leukoencephalopathy, cortical dysplasia and malformations of the temporal lobe and the hippocampus. Since the filter papers from neonatal screening are not kept for ever, perhaps the idea of doing so ought to be considered, given the possibilities they offer for retrospective studies.

INTRODUCTION: Benign paroxysmal vertigo (BPV) is characterised by the sudden onset of brief recurring episodes of loss of balance, sometimes accompanied by vegetative symptoms, which tend to disappear spontaneously in a matter of months or years and have no intercritical alterations. PATIENTS AND METHODS: We analyse the clinical and developmental characteristics of the patients who were listed as possible cases of benign paroxysmal vertigo in the database of the Neuropaediatric Unit of the Hospital Miguel Servet in Zaragoza over a 14 year period. Clinical records were reviewed and cases no longer controlled were contacted by telephone. RESULTS: 18 patients were considered to be cases of BPV, with the typical criteria, and 13 were found to be possible BPV (p-BPV). The atypical data of the p-BPV included late age of onset, prolonged persistence of the episodes and long duration of each episode. Neuroimaging was performed in 8 (44%) of the BPV and 10 (77%) of the p-BPV, and electroencephalogram recordings were carried out in 15 (83%) of the BPV and 11 (85%) of the p-BPV, with normal results in all cases. CONCLUSIONS: Establishing a diagnosis of BPV with strict criteria can mean that some atypical cases are excluded. As no biological marker is available, the diagnosis is clinical-developmental and sometimes complementary tests need to be conducted in order to rule out other pathological conditions. A broader clinical spectrum, cases in which the episodes last longer and a greater range of ages of onset and complete remission are all possible. A diagnosis of BPV should reassure the patients' families as it is a benign process that tends to disappear spontaneously.
