Early hemispherectomy in catastrophic epilepsy A neuro-cognitive and epileptic long-term follow-up

SummaryThe authors report their experience about a neuro-cognitive and epileptic long-term follow-up of children with catastrophic epilepsy treated with hemispherectomy in the first 5 years of life.Nineteen children with resistant epilepsy that significantly interfered with their neuro-cognitive development underwent hemispherectomy within 5 years of life (mean: 2 years, 3 months; range: 5 months to 5 years). All patients were assessed before surgery and after, at least at the end of the follow-up (mean: 6 years and 6 months; range: 2–11 years and 2 months) with a full clinical examination including motor ability and functional status evaluation as well as behaviour observation, neuroimaging and an ictal/interictal prolonged scalp video-EEG.A seizure-free outcome was obtained in 73.7% of patients. Gross motility generally improved and cognitive competence did not worsen, with an evident progress in two cases.Consistently with previous reports, evolution was worse in cortical dysplasia than in progressive or acquired vascular cerebropathies. The excellent epileptic outcome and the lack of developmental deterioration in comparison with other more aged series seem to suggest a possible better evolution in earlier surgery treatment. To confirm this suggestion, however, further experience with larger series is needed

Robotic Technology in Pediatric Neurorehabilitation. A Pilot Study of Human Factors in an Italian Pediatric Hospital

The introduction of robotic neurorehabilitation among the most recent technologies in pediatrics represents a new opportunity to treat pediatric patients. This study aims at evaluating the response of physiotherapists, patients and their parents to this new technology. The study considered the outcomes of technological innovation in physiotherapists (perception of the workload, satisfaction), as well as that in patients and their parents (quality of life, expectations, satisfaction) by comparing the answers to subjective questionnaires of those who made use of the new technology with those who used the traditional therapy. A total of 12 workers, 46 patients and 47 parents were enrolled in the study. Significant differences were recorded in the total workload score of physiotherapists who use the robotic technology compared with the traditional therapy (p < 0.001). Patients reported a higher quality of life and satisfaction after the use of the robotic neurorehabilitation therapy. The parents of patients undergoing the robotic therapy have moderately higher expectations and satisfaction than those undergoing the traditional therapy. In this pilot study, the robotic neurorehabilitation technique involved a significant increase in the patients' and parents' expectations. As it frequently happens in the introduction of new technologies, physiotherapists perceived a greater workload. Further studies are needed to verify the results achieved

Reversible aphasic disorder induced by lamotrigine in atypical benign childhood epilepsy

Purpose: We studied an eleven year-old girl with atypical, benign partial epilepsy who acutely presented a severe aphasia associated with marked EEG deterioration after lamotrigine administration. A parallel monitoring of language disorders and EEG changes during the gradual withdrawal of lamotrigine was performed in order to evaluate their possible correlation with lamotrigine administration. Methods: Detailed neuropsychological and linguistic examinations in association with awake and sleep EEG were periodically performed. Results: The evolution of the aphasic disorder was closely related to the EEG abnormalities, and disappeared after the withdrawal of lamotrigine. Conclusions: We considered the hypothesis that our case could be an expression of a paradoxical reaction to lamotrigine, in which the transitory aphasic disorder was sustained by an epileptiform electric activation

PRRT2 mutations in familial infantile seizures, paroxysmal dyskinesia, and hemiplegic migraine

OBJECTIVE: To perform a clinical and genetic study of a family with benign familial infantile seizures (BFIS) and, upon finding a PRRT2 gene mutation, to study a cohort of probands with a similar phenotype. We extended the study to all available family members to find out whether PRRT2 mutations cosegregated with additional symptoms. METHODS: We carried out a clinical and genealogic study of a 3-generation family and of 32 additional probands with BFIS (11 families), infantile convulsions and paroxysmal choreoathetosis (ICCA) (9 families), BFIS/generalized epilepsy with febrile seizures plus (5 families), and sporadic benign neonatal or infantile seizures (7 probands/families). We performed a genetic study consisting of linkage analysis and PRRT2 screening of the 33 probands/families. RESULTS: We obtained a positive linkage in the 16p11.3-q23.1 chromosomal region in the large BFIS family. Mutation analysis of PRRT2 gene revealed a c.649dupC (p.Arg217Profs*8) in all affected individuals. PRRT2 analysis of the 32 additional probands showed mutations in 10, 8 familial and 2 sporadic, probands. Overall we found PRRT2 mutations in 11 probands with a mutation rate of 11 out of 33 (33%). BFIS co-occurred with migraine and febrile seizures in 2 families, with childhood absence epilepsy in one family and with hemiplegic migraine in one family. CONCLUSION: Our results confirm the predominant role of PRRT2 mutations in BFIS and expand the spectrum of PRRT2-associated phenotypes to include febrile seizures, childhood absence seizures, migraine, and hemiplegic migraine

Early development in Dravet syndrome; visual function impairment precedes cognitive decline

Aim of the study was to describe prospectively the early neuropsychological evolution including the first pre-cognitive stages of the Severe Myoclonic Epilepsy in Infancy (SMEI) or Dravet syndrome. Five cases, four of whom since before a diagnostic evidence of the Dravet syndrome, were followed up. Full clinical assessment including developmental, visual function and behaviour assessments were serially performed. In four cases, a variable onset age of cognitive decline assessed with developmental scales was preceded some months before by an impairment of visual function; the remaining patient during all the course of follow-up till 51 months of age showed a normal development without visual impairment. A cognitive decline with variable onset was generally confirmed in Dravet syndrome. The previous early impairment of visual function seems to herald the cognitive decline and provides useful prognostic information; furthermore, it possibly suggests some clues for a better understanding of the mechanisms of cognitive deterioration in this syndrome

Inv dup 15 syndrome: Case report with epilepsy onset in the first year

Inverted duplicated chromosome 15 (inv dup 15) syndrome is a genetic disorder characterized by facial dysmorphisms, psychomotor retardation, pervasive developmental disorder and neurological signs such as hypotonia and epilepsy. We describe a case of infantile spasms and myoclonia associated with invdup 15. In the literature only four cases of inv dup15 with early onset spasms was described. We suggest that a karyotype must be obtained in patients with unexplained infantile spasms, specially if associated to hypotonia and minor dysmorphic signs
