Abstract
AbstractNeonatal encephalitis by either enteroviruses (EVs) or parechoviruses (PeVs) is often complicated by hemispheric periventricular white matter lesions. Although showing many similarities, the two types of encephalitis differ in some clinical and laboratory aspects, mostly because PeV encephalitis does not show any change of protein and white cell content in the cerebrospinal fluid, and clinically, the onset of PeV encephalitis is often marked by early seizures accompanying a fever of sepsis-like disease. Instead, no difference exists relative to the white matter lesions, which are constantly described as periventricular, even in rare detailed neuropathological studies. Herein, taking a cue from a neonate with EV encephalitis who showed occipital white matter lesions involving the overlying cortex, but completely sparing the periventricular area, we demonstrate that the brain lesions in EV encephalitis in newborns can be more extended than known. To our knowledge, the not-periventricular involvement of the white matter with EV encephalitis has never been described so far, as well as the potential of EV to injure the cortex. We confirm the pathogenetic role of a vascular mechanism for the tissue injury, but other proposed mechanisms are also discussed. It is noteworthy that the neurological outcome of this newborn remained favorable, and no epileptic seizures occurred in the first few days nor afterward.

Abstract
We report on a patient with terminal deletion of the long arm of chromosome 14 displaying brain interhemispheric fusion limited to the midline anterior frontal cortex associated with hypoplastic corpus callosum and incomplete rotation of the left hippocampus in a clinical setting of motor and intellectual disability with poor language, and social behavior abnormalities with aggressiveness. Some possible correlations between clinical signs and symptoms and various aspects of the complex brain malformation are briefly discussed and compared with other known abnormalities of chromosome 14. The different neuropathology of the most common forms and the new forms of holoprosencephaly recently described is also discussed and leads us to suggest classifying the interhemispheric fusion of this case as a "minimal" form of holoprosencephaly. This appears to be the first description in a 14q deletion patient.

Abstract
Niemann-Pick type C is an autosomal recessive lipid storage disease caused by mutations in the NPC1 or NPC2 gene. In childhood-onset Niemann-Pick type C, the usual course is slowly progressive, with normal cerebral magnetic resonance at onset. Here the authors present the case of a patient carrying 2 compound heterozygous NPC1 mutations: the known nonsense mutation (p.Trp833X) in exon 16 and a novel missense mutation (p.Ile609Phe) in exon 12. At onset, the patient presented ataxia, cognitive decline, and epilepsy, with early cerebral atrophy and marked cerebellar vermis atrophy. The course of the disease was rapid, and the patient died within 1-2 years of onset. A possible phenotype-genotype correlation is discussed. This case further expands the clinical spectrum and the genetic heterogeneity of Niemann-Pick type C due to NPC1 mutations.

Abstract
PURPOSE To characterize epileptic phenotype, electroencephalography (EEG) features, and epileptic evolution in patients with ring 14 r(14) syndrome. METHODS Twenty-two patients with ring chromosome 14 were enrolled in the study. We examined age at onset, seizure semiology and frequency at onset and at follow-up, drug responsiveness/resistance, and interictal/ictal EEG data. The degree of severity of the epileptic phenotype negatively influences child cognitive development. KEY FINDINGS The incidence of epilepsy in patients with r(14) syndrome is virtually 100%, characterized by early onset, polymorphic seizures, and drug-resistant seizures. In addition, we ascertained focal secondarily generalized epilepsy, seizure cluster tendency, frequent status epilepticus, and a rather typical epilepsy evolution. EEG abnormalities consisted of slow background activity with pseudoperiodic bursts of generalized slow waves in the early stage, focal frontotemporal or temporoposterior slow waves with multifocal spikes interposed, and unusual rhythmic fast recruiting posterior spikes followed by secondary generalization. The degree of severity of the epileptic phenotype negatively influences child cognitive development. SIGNIFICANCE This study provides a more precise definition of seizure types, natural history, and drug responsiveness of r(14) syndrome, a highly epileptogenic chromosomal condition.

Abstract
Mowat-Wilson syndrome (MWS) is a genetic disease caused by heterozygous mutations or deletions of the ZEB2 gene and is characterized by distinctive facial features, epilepsy, moderate to severe intellectual disability, corpus callosum abnormalities and other congenital malformations. Epilepsy is considered a main manifestation of the syndrome, with a prevalence of about 70-75%. In order to delineate the electroclinical phenotype of epilepsy in MWS, we investigated epilepsy onset and evolution, including seizure types, EEG features, and response to anti-epileptic therapies in 22 patients with genetically confirmed MWS. Onset of seizures occurred at a median age of 14.5 months (range: 1-108 months). The main seizure types were focal and atypical absence seizures. In all patients the first seizure was a focal seizure, often precipitated by fever. The semiology was variable, including hypomotor, versive, or focal clonic manifestations; frequency ranged from daily to sporadic. Focal seizures were more frequent during drowsiness and sleep. In 13 patients, atypical absence seizures appeared later in the course of the disease, usually after the age of 4 years. Epilepsy was usually quite difficult to treat: seizure freedom was achieved in nine out of the 20 treated patients. At epilepsy onset, the EEGs were normal or showed only mild slowing of background activity. During follow-up, irregular, diffuse frontally dominant and occasionally asymmetric spike and waves discharges were seen in most patients. Sleep markedly activated these abnormalities, resulting in continuous or near-to-continuous spike and wave activity during slow wave sleep. Slowing of background activity and poverty of physiological sleep features were seen in most patients. Our data suggest that a distinct electroclinical phenotype, characterized by focal and atypical absence seizures, often preceded by febrile seizures, and age-dependent EEG changes, can be recognized in most patients with MWS.

Abstract
Spastic paraplegia 3A is the second most common form of hereditary autosomal dominant spastic paraplegia. This form is mainly associated with an early age of onset and pure phenotype, although recently complicated forms were reported. We describe a patient carrying a new C>T P344S>CT mutation in exon 10 of the spastic paraplegia 3A gene with unusual, complicated, and extremely severe phenotype. At the last neurologic examination performed at 17 years of life, the patient disclosed spastic tetraparesis, sensorimotor axonal neuropathy, cognitive and cranial nerve impairment, mild pes cavus, and distal amyotrophy.

Abstract
AIMS To determine efficacy and safety of corticosteroid treatment in patients with severe Sydenham's chorea paralytic form. METHODS This is a 4 years observational study on ten patient with severe paralytic form of Sydenham's chorea unresponsive to neuroleptics and antiepileptics agents, treated with intravenous methylprednisolone followed by oral deflazacort therapy. Chorea paralytica patients were bedridden, unable to take independent steps, showed severe generalized hypotonia and were hospitalized for 3-4 weeks. Additional clinical evaluations were undertaken at 1, 3 and 6 months and 1, 2 and 4 years from onset of chorea. Severity chorea at the onset and during follow up was rated according to Universidade Federal de Minas Gerais (UFMG) Sydenham's Chorea Rating Scale (USCRS). In all children video-recording was performing at onset and during clinical follow-up. RESULTS We reported a significant improvement in swallowing and chewing with partial recovery of language 2-3 days after starting intravenous methylprednisolone treatment and complete disappearance of movement disorders after 3-4 weeks of treatment. All our patients were followed for 4 years from onset and none experienced relapse of chorea, other movement disorders or psychiatric disturbances. The treatment with deflazacort was well-tolerated in all children with no significant side effects reported. CONCLUSION Our data showed that high dose of methylprednisolone intravenously followed by deflazacort therapy may be effective and well-tolerated in children with severe paralytic form of Sydenham's chorea.

Abstract
Mutations in the ganglioside-induced differentiation-associated protein 1 (GDAP1) gene may cause severe early-onset inherited neuropathies. Here, the authors report a clinical and neurophysiological follow-up of a Pakistani child with a very early-onset neuropathy carrying a novel homozygous mutation in the GDAP1gene. They discuss the relationship between the several forms of Charcot-Marie-Tooth disease presenting in the first months of life and focus on the literature of GDAP1-associated early-onset neuropathy. This case further expands on the clinical spectrum and the genetic heterogeneity of early-onset inherited neuropathy due to GDAP1 gene mutations.

Abstract
A case of acute and reversible bilateral basal ganglia with thalami involvement associated with serological evidence of Mycoplasma pneumoniae infection is reported. Increased titers of immunoglobulin M antibodies against GM1 ganglioside components were found during an acute phase of neurological illness. Brain magnetic resonance imaging (MRI) showed bilateral involvement of the basal ganglia and thalamus, which disappeared 1 month later. The child recovered fully after corticosteroid and immunoglobulin therapy, and antiganglioside antibodies returned to within the normal range. The authors speculate on the diagnostic hypothesis regarding selective basal ganglia and thalamic involvement and the relationship with anti-GM1 ganglioside immunoglobulin M antibodies.

Most patients with an SPG3A mutation present with a pure phenotype and early-onset disease, although complicated forms with peripheral neuropathy are also reported. We report a new heterozygous S398F mutation in exon 12 of the SPG3A gene causing a very early-onset spastic paraplegia in association with motor axonal neuropathy in a 4-year-old girl resembling diplegic cerebral palsy.

Abstract
A 14-year-old boy with an episode of acute weakness resembling acute demyelinating encephalomyelitis and polyradiculoneuritis after a febrile illness is described. Molecular analysis showed a mutation at codon 164 of the connexin 32 gene. Neuroradiological and neurophysiological follow-up is reported during acute and chronic phases of disease, suggesting that during metabolic stress connexin 32 mutations lead to a loss of normal cellular communication and reversible cell dysfunction in oligodendrocytes and in Schwann cells. These data confirm that altered gating properties of connexin 32 could give rise to acute, transient central and peripheral nervous system symptoms in situations of metabolic stress.

Abstract
ESES (encephalopathy with status epilepticus during sleep) is an epileptic encephalopathy with heterogeneous clinical manifestations (cognitive, motor, and behavioral disturbances in different associations, and various seizure types) related to a peculiar electroencephalography (EEG) pattern characterized by paroxysmal activity significantly activated during slow sleep-that is, a condition of continuous spikes and waves, or status epilepticus, during sleep. The pathophysiologic mechanisms underlying this condition are still incompletely understood; recent data suggest that the abnormal epileptic EEG activity occurring during sleep might cause the typical clinical symptoms by interfering with sleep-related physiologic functions, and possibly neuroplasticity processes mediating higher cortical functions such as learning and memory consolidation. As in the myth of Penelope, the wife of Odysseus, what is weaved during the day will be unraveled during the night.

Abstract
The ring 14 (r14) syndrome is a rare condition, whose precise clinical and genetic characterization is still lacking. We analyzed a total of 20 patients with r14 and another 9 patients with a linear 14q deletion. The ring was complete, with no apparent loss of chromosome material, in 6 cases; a terminal 14q deletion, varying in size from 0.65 to 5 Mb, was detected in the remaining 14 cases. Deleted ring chromosomes were 70% paternal and 30% maternal. UPD (14) was never detected. With respect to the linear 14q deletions, three were proximal, varying in size from 4 to 7.2 Mb, and six distal, varying in size from 4.8 to 20 Mb. The majority of the linear deletions were also of paternal origin, and UPD (14) was excluded in all cases. Clinically, the r14 syndrome was characterized by a recognizable phenotype, consisting of shortness of stature, a distinctive facial appearance, microcephaly, scoliosis, and ocular abnormalities, which included abnormal retinal pigmentation, strabismus, glaucoma, and abnormal macula. All patients except one had mental retardation. Drug-resistant epilepsy was another highly consistent finding. Aggressive and hyperactive behavior was noted in about half of the patients. Based on genotype-phenotype correlations, we could deduce that retinal abnormalities, epilepsy, microcephaly, and mental retardation map within the proximal 14q11.2-q12 region. Likewise, behavior disorders and scoliosis could be assigned to the 14q32 region.

A 3-year-old female infant with Charcot-Marie-Tooth disease type 1A had congenital pes cavus, normal motor development, and duplication of the peripheral myelin protein 22 gene, PMP22. Her father, carrying the same gene duplication, developed neuropathy, tremor, and auditory impairment beginning in early adulthood. This is a case of congenital pes cavus in a Charcot-Marie-Tooth disease type 1A patient. The infant had pes cavus caused by the hereditary sensorimotor neuropathy; the family provides a clear example of clinical anticipation.

Abstract
Autosomal recessive spastic paraplegia with thinning of corpus callosum (ARHSP-TCC) is a complex form of HSP initially described in Japan but subsequently reported to have a worldwide distribution with a particular high frequency in multiple families from the Mediterranean basin. We recently showed that ARHSP-TCC is commonly associated with mutations in SPG11/KIAA1840 on chromosome 15q. We have now screened a collection of new patients mainly originating from Italy and Brazil, in order to further ascertain the spectrum of mutations in SPG11, enlarge the ethnic origin of SPG11 patients, determine the relative frequency at the level of single Countries (i.e., Italy), and establish whether there is one or more common mutation. In 25 index cases we identified 32 mutations; 22 are novel, including 9 nonsense, 3 small deletions, 4 insertions, 1 in/del, 1 small duplication, 1 missense, 2 splice-site, and for the first time a large genomic rearrangement. This brings the total number of SPG11 mutated patients in the SPATAX collection to 111 cases in 44 families and in 17 isolated cases, from 16 Countries, all assessed using homogeneous clinical criteria. While expanding the spectrum of mutations in SPG11, this larger series also corroborated the notion that even within apparently homogeneous population a molecular diagnosis cannot be achieved without full gene sequencing.

Abstract
We report an atypical neurophysiologic pattern of isolated vitamin E deficiency in a 13-year-old boy. Electroneurography- electromyography, somatosensory evoked potentials, serum vitamin E concentration and genetic analysis of the alpha-tocopherol transfer protein gene were performed. Nerve conduction study failed to show peripheral neuropathy whereas needle electromyography of distal muscles demonstrated chronic neurogenic motor unit potentials. Both clinical and neurophysiologic data fulfilled the criteria of distal hereditary motor neuropathy. Later on, somatosensory-evoked potential displayed absence of spinal and central response. The serum vitamin E level was low, and the patient was found to be homozygous for a 513insTT mutation in exon 3 of the alpha-tocopherol transfer protein gene. To our knowledge this is the first case of isolated deficiency of vitamin E that presents the classic neurophysiologic and clinical features of distal hereditary motor neuropathy.

Abstract
This article presents a 6-year-old girl who developed acute unilateral third cranial nerve palsy in the absence of any other sign of central nervous system involvement. Raised titers of immunoglobulin M antibodies against GM1, GD1a, and GD1b ganglioside components were demonstrated. Ten days earlier, the girl had experienced acute gastroenteritis with positive specific immunoglobulin M antibodies against enterovirus. The results of all other laboratory tests usually performed for infectious diseases were negative, and neuroradiologic findings were also normal. Oral prednisone was administered for a few days, and the ophthalmoparesis fully resolved within 1 month. Two months later, a second episode of isolated ophthalmoparesis occurred, again associated with a positive immunoglobulin M reaction against GM1, GD1a, and GD1b antigens. This report discusses the relationship between acute isolated ophthalmoparesis and antiganglioside antibodies.

Abstract
Complex tics have been widely reported in literature, especially in children with Tourette syndrome. We describe the case of a fracture line of both peroneal bones in a 13-year-old child with Tourette syndrome and obsessive-compulsive disorder. He was admitted to our hospital because of pain in his legs. Radiography showed fractures of both peroneal bones, more marked on the left side. The clinical history was strongly suggestive of obsessive-compulsive disorder and Tourette syndrome with associated simple and complex motor tics. Radiographic follow-up showed spontaneous resolution of the fractures.

Abstract
OBJECTIVE To determine if laminin-alpha2 deficiency is due to mutations in the LAMA2 gene or secondary to mutations in other congenital muscular dystrophy genes. METHODS We performed molecular analysis of LAMA2, by single-strand conformation polymorphism and sequencing, in 15 patients with undetectable or greatly reduced laminin-alpha2 expression. We also performed 4 prenatal diagnoses and investigated a founder effect. RESULTS We found 1 known and 9 previously undescribed LAMA2 mutations spanning all protein domains. These were nonsense or frameshifts causing laminin-alpha2 absence or, in 1 case, a homozygous missense mutation producing partial protein expression and milder phenotype. LAMA2 mutations were undetected in 5 patients, in 2 of whom FKRP mutations explained the phenotype. In 3 prenatal cases, the fetus was heterozygous for the mutation of interest and pregnancy continued; in 1 case, the fetus was affected and aborted. In 2 patients, the Cys967Stop mutation and identical haplotypes flanking the LAMA2 gene indicated a founder effect. CONCLUSIONS The clinical phenotype was severe in most patients with LAMA2 mutations and associated with undetectable protein expression. One case with no protein and another with partial expression had milder phenotypes. Typical white matter alterations on magnetic resonance imaging were found in all patients with LAMA2 mutations, supporting the utility of magnetic resonance imaging in differential diagnosis. The founder mutation (Cys967Stop) probably originated in Albania. Genetic characterization of affected families is mainly of use for prenatal diagnosis.
