RESUMEN
INTRODUCTION: The recent advances in the therapies for some neuromuscular disorders imply a better prognosis. As a consequence, health-related quality of life has emerged as a core outcome. It is particularly important to know both the self-perceived health-related quality of life by children, as soon as possible, as well as the parental perception. Therefore, it is essential to have valid and specific scales for proper assessment. AIM: To assess the validity and reliability of the Spanish version of Pediatric Quality of Life Inventory (PedsQL) Neuromuscular Module for self-perceived and parent perceived quality of life of children aged 5-7 with neuromuscular disorders. SUBJECTS AND METHODS: Cross-cultural validity of the Spanish version was carried out with the permission of the Mapi-Research-Trust. Subsequently, a test-retest was administered to 27 children aged 5-7 and 37 parents in order to evaluate internal consistency, intra-observer reliability and construct validity. RESULTS: The Cronbach alpha coefficient showed good internal consistency for children and was rated as excellent by parents. Furthermore, the intra-observer correlation indicated an excellent reliability for both. Construct validity analysis suggested that a new scale structure with more dimensions might be more adequate. Moreover, said structure will also explain a greater percentage of variability. CONCLUSION: The Spanish version of PedsQL Neuromuscular Module for the self-perceived and parent-perceived quality of life of children aged 5-7 showed good internal consistency and reliability.

Spinal muscular atrophy (SMA) is an autosomal recessive disease caused by homozygous deletions or loss-of-function mutations in SMN1, which result in a degeneration of motor neurons in the spinal cord and brain stem. Even without a randomized placebo-controlled trial, salbutamol has been offered to patients with SMA in the neuromuscular clinics of most of hospitals for many years. We describe the response to salbutamol in 48 patients with SMA type II who were not taking any other medication. We investigate the changes over an eighteen-month period in motor functional scales and we analyze side effects and subjective response to treatment. Our results suggest that oral administration of salbutamol might be helpful in the maintenance of motor function in patients with SMA type II. An apparent beneficial effect was observed in functional scales of children under the age of 6, especially during the first 6 months of therapy. The majority of patients of all ages referred some kind of subjective positive effect associated with therapy intake. Salbutamol seemed safe and was well tolerated without serious side effects.

Congenital myasthenic syndromes (CMS) are a heterogeneous group of genetic disorders, all of which impair neuromuscular transmission. Epidemiological data and frequencies of gene mutations are scarce in the literature. Here we describe the molecular genetic and clinical findings of sixty-four genetically confirmed CMS patients from Spain. Thirty-six mutations in the CHRNE, RAPSN, COLQ, GFPT1, DOK7, CHRNG, GMPPB, CHAT, CHRNA1, and CHRNB1 genes were identified in our patients, with five of them not reported so far. These data provide an overview on the relative frequencies of the different CMS subtypes in a large Spanish population. CHRNE mutations are the most common cause of CMS in Spain, accounting for 27% of the total. The second most common are RAPSN mutations. We found a higher rate of GFPT1 mutations in comparison with other populations. Remarkably, several founder mutations made a large contribution to CMS in Spain: RAPSN c.264C > A (p.Asn88Lys), CHRNE c.130insG (Glu44Glyfs*3), CHRNE c.1353insG (p.Asn542Gluf*4), DOK7 c.1124_1127dup (p.Ala378Serfs*30), and particularly frequent in Spain in comparison with other populations, COLQ c.1289A > C (p.Tyr430Ser). Furthermore, we describe phenotypes and distinguishing clinical signs associated with the various CMS genes which might help to identify specific CMS subtypes to guide diagnosis and management.

Since Engel reported the first case of congenital myasthenia in 1977 and the first pathogenic gene was found in 1995, knowledge about congenital myasthenic syndromes has continued to grow. Over the years, the pathogenic basis, its clinical features, the phenotype-genotype correlations that have been established and its therapeutic management have all been described. In this group of diseases the safety margin of neuromuscular transmission is altered by different mechanisms: in the synthesis or storage of acetylcholine quanta in the synaptic vesicles, in the calcium-mediated release of acetylcholine in the nerve terminal or in the efficiency of the quantum released to generate a post-synaptic depolarisation. Increased knowledge about them has enabled a number of different therapeutic strategies to be established. In this review the main updates on these syndromes are reported, including: the genes described as classifying 50% of cases, their current classification based on the localisation of the proteins that alter neuromuscular transmission, including a new group of congenital myasthenias, glycosylation disorders, the main key diagnoses and the therapeutic management of this group of under-diagnosed patients.
TITLE: Estado actual de los sindromes miastenicos congenitos.Desde la descripcion de Engel del primer caso de miastenia congenita en 1977 y el hallazgo en 1995 del primer gen patogeno, el conocimiento de los sindromes miastenicos congenitos se ha ido desarrollando, y se han descrito la base patogena, sus caracteristicas clinicas, las correlaciones fenotipo-genotipo establecidas y su abordaje terapeutico. En este grupo de enfermedades se altera el margen de seguridad de la transmision neuromuscular por distintos mecanismos: en la sintesis o almacenamiento de los quantum de acetilcolina en las vesiculas sinapticas, en la liberacion de acetilcolina en el nervio terminal mediada por calcio o en la eficiencia de la cuanta liberada para generar una despolarizacion postsinaptica. Su conocimiento ha permitido establecer distintas estrategias terapeuticas. En esta revision se describen las principales actualizaciones de estos sindromes: los genes descritos que clasifican un 50% de los casos, su clasificacion actual basandose en la localizacion de las proteinas que alteran la transmision neuromuscular, incluyendo un nuevo grupo de miastenias congenitas, los trastornos de la glicosilacion, las principales claves diagnosticas y el abordaje terapeutico de este grupo de pacientes infradiagnosticados.

Introducción. La neurofibromatosis de tipo 2 (NF2) es un trastorno neuroectodérmico con patrón de herencia autosómico dominante que condiciona una predisposición para desarrollar tumores de varios tipos en el sistema nervioso central y periférico. Se asocia también con alteraciones oculares y cutáneas. Caso clínico. Varón de 12 años con diagnóstico de NF2 de acuerdo con los criterios de Baser et al e inicio en la infancia. Se realiza una revisión bibliográfica sobre la evolución de los criterios diagnósticos en los niños. Conclusiones. El modo de presentación de la NF2 en la infancia difiere de la presentación en los adultos. Las manifestaciones iniciales de NF2 en los niños son las alteraciones oculares y cutáneas, no las auditivas. La clínica de inicio más frecuente en la edad pediátrica es la tríada de cataratas subcapsulares posteriores, lesiones intracutáneas en forma de placa o tumores nodulares subcutáneos, y síntomas neurológicos secundarios a la afectación de pares craneales distintos al VIII par, tronco encefálico o médula espinal. Debido a que los criterios diagnósticos de NF2 son menos sensibles en los pacientes pediátricos, los niños con cataratas congénitas o de aparición precoz y manifestaciones cutáneas típicas de NF2 deben ser seguidos estrechamente (AU)
INTRODUCTION. Neurofibromatosis type 2 (NF2) is a dominantly inherited neuroectodermal syndrome that predispose to the development of tumors of the central and peripheral nervous system. Additional features include eye and skin abnormalities. CASE REPORT. A 12-year old male with diagnosis of MF2 according to Baser et al and presentation in childhood was included. A comprehensive bibliographic review of evolution of the diagnostic criteria for NF2 in children was performed. CONCLUSIONS. The pattern of presentation of NF2 in childhood differs from adulthood in many aspects. Ophthalmologic and skin manifestations, and not an auditory dysfunction, are the most common initial symptoms in prepuberal-onset NF2. The most frequent symptoms and signs at presentation are posterior subcapsular cataract, skin manifestations as NF2 plaques and/or peripheral nerve tumors, and neurological dysfunction related to isolated or multiple cranial nerve deficits (other than nerve VIII), brainstem masses or spinal masses. As sensitivity of diagnostic criteria in children is low, those prepuberal patients with congenital or early-onset cataracts and typical skin manifestations of NF2 should be systematically assessed (AU)

Advances in genetic testing applied to child neurology have enabled the development of genetic tests with greater sensitivity in elucidating an etiologic diagnosis for common neurological conditions. The objective of the current study was to examine child neurologists' perspectives and insights into genetic testing. We surveyed 118 Spanish child neurologists, exploring their knowledge, attitudes, and practices concerning genetic tests. All of them had requested at least one genetic test in the past six months. Global developmental delay or intellectual disability in absence of a strong specific etiologic suspicion and autism spectrum disorders were the disorders for which genetic testing was most frequently requested. The most commonly requested genetic test was CGH-array. Overall, child neurologist perception of readiness for making genetic-related decisions was not bad, although many would like to have a greater support from geneticists and were interested in increasing the time dedicated to genetics within their continuing education program. These data have important implications for future practice, research, and education.

Congenital myasthenic syndromes (CMS) are a heterogeneous group of genetic disorders. Mutations in CHRNE are one of the most common cause of them and the É1267delG frameshifting mutation is described to be present on at least one allele of 60% of patients with CHRNE mutations. We present a comprehensive description of the heterogeneous clinical features of the CMS caused by the homozygous 1267delG mutation in the AChR Æ subunit in nine members of two large Gipsy kindreds. Our observations indicate that founder Roma mutation 1267delG leads to a phenotype further characterized by ophthalmoplegia, bilateral ptosis, and good response to pyridostigmine and 3,4-DAP; but also by facial weakness, bulbar symptoms, neck muscle weakness, and proximal limb weakness that sometimes entails the loss of ambulation. Interestingly, we found in our series a remarkable proportion of patients with a progressive or fluctuating course of the disease. This finding is in some contrast with previous idea that considered this form of CMS as benign, non progressive, and with a low impact on the capacity of ambulation.

INTRODUCTION: Cluster headache is a rare cause of primary headache in children. We report four cases with a mean age of onset of 8.6, ranged from 2 to 13 years. CASE REPORTS: Three males and one female with onset at 2, 7, 13, and 12 years-old, respectively, were included. The symptoms of all patients fulfill the criteria for the diagnosis of cluster headache according to the International Society of Headache. CONCLUSIONS: Despite being rare during childhood, cluster headache should be part of the differential diagnosis of headache in childhood. This report highlights the variable features of this disorder in children, often misdiagnosed. It can be useful in making a quick diagnosis and starting the appropriate treatment early. Verapamil was more effective than flunarizine in terminating the headache in our patients. Oxygen treatment and triptans resulted the treatments with the best response in acute cluster headache.
TITLE: Cefalea en racimos en edad pediatrica: descripcion de cuatro casos y revision de la bibliografia.Introduccion. La cefalea en racimos es una cefalea primaria de origen trigeminoautonomico cuyo inicio en la infancia es infrecuente. Se presentan cuatro casos en los que el inicio de la sintomatologia se produjo entre los 2 y los 13 años. Casos clinicos. Se incluyen tres varones y una niña con inicio a los 2, 7, 13 y 12 años, respectivamente. Los cuatro pacientes cumplen los criterios propuestos por la tercera edicion de la Clasificacion Internacional de las Cefaleas ICHD-III (beta). Conclusiones. A pesar de ser poco frecuente durante la edad pediatrica, la cefalea en racimos debe formar parte del diagnostico diferencial de un niño que consulta por cefalea. Subrayamos la importancia de conocer sus criterios diagnosticos para evitar el retraso diagnostico que se ha descrito con frecuencia. En nuestros pacientes, el tratamiento con verapamilo resulto mas eficaz que el tratamiento con flunaricina. Los tratamientos con mejor respuesta en fase aguda fueron la oxigenoterapia y los triptanes.

UNLABELLED: Harlequin syndrome (HS) is a rare autonomic disorder due to a hemifacial cutaneous sympathetic denervation. It is characterized by unilateral diminished sweating and flushing of the face even though after heat or prolonged exercise. It is typically acquired. Congenital cases only represent a 6% of all individuals with HS. All congenital HS cases reported so far showed a concomitant Horner syndrome, probably due to a stellate ganglion involvement. HS represents an uncommon autonomic disorder due to a hemifacial cutaneous sympathetic denervation. It is clinically characterized by a dramatic alteration in facial appearance: ipsilateral denervated pale and dry half from the other intact red and moist half. CONCLUSION: We present, to the best of our knowledge, the first case of a patient with a congenital HS as an isolated phenomenon.

Congenital myopathies are a group of inherited muscle disorders characterized by hypotonia, weakness and a non-dystrophic muscle biopsy with the presence of one or more characteristic histological features. Neuromuscular transmission defects have recently been reported in several patients with congenital myopathies (CM). Mutations in KLHL40 are among the most common causes of severe forms of nemaline myopathy. Clinical features of affected individuals include fetal akinesia or hypokinesia, respiratory failure, and swallowing difficulties at birth. Muscle weakness is usually severe and nearly half of the individuals have no spontaneous antigravity movement. The average age of death has been reported to be 5 months in a recent case series. Herein we present a case of a patient with a nemaline myopathy due to KLHL40 mutations (c.604delG, p.Ala202Argfs*56 and c.1513G>C, p.Ala505Pro) with an impressive and prolonged beneficial response to treatment with high-dose pyridostigmine. Myasthenic features or response to ACEI have not previously been reported as a characteristic of nemaline myopathy or KLHL40-related myopathy.

Rapsyn (RAPSN) mutations are a common cause of postsynaptic congenital myasthenic syndromes. We present a comprehensive description of the clinical and molecular findings of ten patients with CMS due to mutations in RAPSN, mostly with a long-term follow-up. Two patients were homozygous and eight were heterozygous for the common p.Asn88Lys mutation. In three of the heterozygous patients we have identified three novel mutations (c.869T > C; p.Leu290Pro, c.1185delG; p.Thr396Profs*12, and c.358delC; p.Gln120Serfs*8). In our cohort, the RAPSN mutations lead to a relatively homogeneous phenotype, characterized by fluctuating ptosis, occasional bulbar symptoms, neck muscle weakness, and mild proximal muscle weakness with exacerbations precipitated by minor infections. Interestingly, episodic exacerbations continue to occur during adulthood. These were characterized by proximal limb girdle weakness and ptosis, and not so much by respiratory insufficiency after age 6. All patients presented during neonatal period and responded to cholinergic agonists. In most of the affected patients, additional use of 3,4-diaminopyridine resulted in significant clinical benefit. The disease course is stable except for intermittent worsening.

El dolor torácico, un motivo de consulta poco frecuente en pediatría, es causante de una gran preocupación tanto en el paciente como en su familia, al ser percibido como una patología cardiaca potencialmente letal. Si bien en la mayoría de los casos se trata de un proceso benigno, también puede ser reflejo de una enfermedad grave. Exponemos los casos de 6 niños que consultaron en el servicio de urgencias por precordalgia, y que fueron diagnosticados de hernia diafragmática postraumática, neumotórax espontáneo, rabdomiosarcoma, linfoma no hodgkiniano, ganglioneuroma y síndrome de Wolff-Parkinson-White(AU)
Chest pain constitutes a rare case in pediatrics and is a worrisome symptom for both patients and their families, who often fear a potentially lethal cardiac disease. Although in most cases it is a benign process, it can also be secondary to an underlying serious disease. We present 6 children who consulted in the Emergency Department because of chest pain, whose outright diagnoses were: post-traumatic diaphragmatic hernia, spontaneous pneumothorax, rhabdomyosarcoma, non-Hodgkin´s lymphoma, ganglioneuroma and Wolff-Parkinson-White syndrome(AU)
