Alterações de linguagem oral e escreta em crianças pré-escolares e escolares com epilepsia

A epilepsia cursa com diversas comorbidades e, entre elas, estão as alterações de linguagem, que levam a criança a problemas educacionais e sociais desfavoráveis. A etiologia das alterações de linguagem envolve aspectos orgânicos, cognitivos e sociais, ocorrendo, na maioria das vezes, uma interrelação entre todos esses fatores. A idade da primeira crise epiléptica, o tipo de epilepsia, o uso de drogas antiepilépticas e a intervenção medicamentosa em politerapia podem implicar na ocorrência dessas alterações em crianças. O objetivo dessa pesquisa foi verificar a ocorrência de alterações de linguagem em crianças pré-escolares e escolares com diagnóstico de epilepsia atendidas no setor de Neurologia Infantil do Hospital de Pediatria Professor Heriberto Ferreira Bezerra. Caracterizou-se como um estudo prospectivo e transversal realizado com 90 crianças com epilepsia, submetidas à avaliação fonoaudiológica de linguagem oral e de leitura e escrita e como pesquisa interdisciplinar uma vez que envolveu áreas como a Fonoaudiologia, a Neurologia e a Psicologia. Os critérios de inclusão foram: 1) diagnóstico inequívoco de epilepsia, segundo a definição da ILAE (2005), 2) idade de 3 aos 12 anos, 3) padrão neurológico e desenvolvimento neuropsicomotor normais; os de exclusão: 1) diagnóstico de epilepsia duvidoso, 2) padrão neurológico e desenvolvimento neuropsicomotor alterados, 3) crianças com patologias pediátricas associadas. Foram analisadas as seguintes variáveis: sexo, idade da primeira crise epiléptica, tipo de crise epiléptica, regime de tratamento, presença de crise epiléptica, frequência à escola, tipo de escola e repetência. A análise estatística centrou-se na análise descritiva; determinou-se a razão de chances (odds ratio), adotando-se um intervalo de confiança de 95%; e na aplicação do teste exato de Fisher, levando-se em consideração p<0,05. Portanto, no que se refere à presença de alterações de linguagem oral, pôdese observar que o início das crises epilépticas durante o período de aquisição e desenvolvimento da linguagem oral bem como o tratamento medicamentoso neste período podem interferir no desenvolvimento da linguagem devido à imaturidade do sistema nervoso central além dos aspectos socioambientais, uma vez que o estigma e as crenças errôneas interferem negativamente no processo interacional tão importante para a aquisição e desenvolvimento da linguagem, o que também repercute nas habilidades de leitura e escrita. Dessa forma percebe-se a importância da atuação de uma equipe interdisciplinar (Fonoaudiologia, Psicologia e Neurologia Infantil) no processo avaliativo e no acompanhamento dos pacientes com epilepsia, o que trará benefícios psicosocioafetivos no que se refere à reorganização da sua qualidade de vida e, consequentemente, de seus familiares.

A prática de atividade física de crianças e adolescentes com e sem epilepsia

The epilepsy is one of the neurological disorders more common in the pediatric period, and which interferes significantly in the psycho and social life of children and teenagers. The objective of this study was analyzing the practice of sedentary practices, physicals, traditional infant fun and games of children and teenagers with and without epilepsy. The study was prospective, transversal descriptive, done with 60 children and teenagers with epilepsy (Epileptic Group - EG) patients from Pediatric Neurology Clinic of the Centre Integrated Health Lineu Araújo and 60 children and teenagers without epilepsy (Control Group - CG) students from municipal public school, both of the two groups paired with the same age (age group 7 to 14 years) of both the genders (female = 25/41,6% and male = 35/58,3%) of the Teresina city Piauí. It was done two pattern questionnaires, one applied to children and teenagers of the EG and CG to identify the sedentary activities, physical and traditional infant games and other to the parents/responsible of the EG about the clinical and demographic information. The results permitted the elaboration of two manuscripts: a) the first one titled The Practice of Sedentary and Physical Activities of Children and Teenagers with Epilepsy which showed significant difference in the sedentary activities of playing with car toy (p=0,021) to the EG and reading to the CG (p=0,001); in the physical activities the school physical education (p=0,001) and riding a bike (p=0,014) to the CG; b) the second one The Practice of Infant Games and Fun the children and teenagers with and without Epilepsy in this one the playing with marble presented significant difference (p=0,016) to the CG, despite the girls of the two groups don t do this activity. Observing the distribution of frequencies, it was verified that in the play catch-up and hide-and-seek and burn the EG plays more than the CG both in female and male gender. The girls of the EG play less skip, 60 while the boys of the two groups don t play. Elastic jump the girls of the two groups play in a same frequency and the boys don t participate of this fun. The seizures were found to occur during: soccer (23,3%); hide-and-seek (6,6%) and running (3,3%). In the sedentary activities, seizures were reported to occur: resting and watching TV (18,3%), sleeping (36,0%); sitting (13,3%) and lying down (11,7%). Our results showed that the epileptic group and the controls group engage in the same activities, although the epileptic group participates less than the controls. Although the EG had presented a bigger percentage of generalized attacks, they don t occur during the practice of formal physical activities. The research was developed by a multidisciplinary team, and this contributed a lot to the realization of this study

Protocolos de investigação de variáveis psicológicas na epilepsia infantil

Epilepsy is a common chronic condition in the childhood and its diagnosis reveals psychological, social and family difficulties, that seem to be related with beliefs and quality of parents-children interaction. The purpose of this paper is to schematize investigation strategies for the psychological variables: beliefs, impact of the disease, family relationship, identification of changes. Based upon collected reports of epileptic children's parents and upon surveyed aspects of the literature, psychological questionnaires were elaborated to identify important variables that affect the child's epilepsy life and his family. The use of more appropriate investigation procedures facilitates the psychological evaluation and ensures the collection of data.

Investigação do potencial cortical provocado visual para padrão reverso em pacientes diagnosticados com epilepsia parcial e generalizada

Este trabalho avaliou o potencial cortical provocado visual de crianças com história de epilepsia com o objetivo de identificar marcadores eletrofisiológicos que indicassem alterações corticais em epilepsia. Foram estudados 34 sujeitos com história de epilepsia (18 sujeitos com epilepsia parcial e 16 com epilepsia generalizada). O grupo controle foi composto por 19 sujeitos sem história de crises epilépticas com faixa etária semelhante aos pacientes. Os componentes do potencial cortical provocado visual transiente para apresentação por padrão reverso de tabuleiros de xadrez foram avaliados quanto à amplitude, tempo implícito e razões de amplitude entre os componentes. Foi observado que os pacientes com epilepsia generalizada apresentaram componente N75 com amplitude maior que os demais grupos, enquanto as razões de amplitude N75/P100 e P100/N135foram menores em pacientes com epilepsia parcial que em outros grupos. Houve fraca correlação linear entre os parâmetros do potencial cortical provocado visual e a idade de início das crises epilépticas ou tempo de utilização das medicações antiepilépticas. Conclui-se que o componente N75 e as razões de amplitude N75/P100 e P100/N135 podem ser bons indicadores eletrofisiológicos para alterações funcionais corticais em epilepsia.

A pilot study of topiramate in children with Lennox-Gastaut syndrome

We conducted an open, add-on study with topiramate (TPM) as adjunctive therapy in Lennox-Gastaut syndrome (LGS), to assess the long-term efficacy and safety and to evaluate quality of life (QL) measurements in the chronic use of TPM. We studied 19 patients (11 male; age ranging from 4 to 14 years) with uncontrolled seizures receiving 2-3 anti-epileptic drugs. Patients were followed up to 36 months of treatment. A questionnaire was used to query parents about QL. Seven patients completed the study at 36 months and seizure frequency was reduced > 75% in 4, and < 50% in 3 patients. Two children became seizure free for more than 24 months. Most side effects were CNS related, with the most frequent being somnolence and anorexia. These were generally transient. One patient dropped-out due to powder in the urine. None of the patients required hospitalization. At 36 months, patients' alertness (2/7), interaction with environment (5/7), ability to perform daily activities (5/7), and verbal performance (6/7) improved on TPM. We conclude that TPM may be useful as adjunctive therapy in the treatment of LGS. The efficacy of TPM was maintained in long-term treatment in more than 40% of patients, long term safety was confirmed and QL improved on TPM.

Dyskinesia induced by phenytoin

Phenytoin is an effective antiepileptic drug, although, it can be associated with many side effects, including dyskinesia. OBJECTIVE: To describe the clinical characteristics of phenytoin induced dyskinesia. METHODS: We investigated the occurrence of involuntary movements in patients followed at our adult and pediatric epilepsy clinics during the period of one year. RESULTS: Three patients presented with phenytoin-induced dyskinesia: one adult with axial and orofacial dyskinesia, and two children with choreoathetosis. They did not have other signs of phenytoin intoxication and had complete recovery after phenytoin withdrawal. CONCLUSION: Phenytoin induced dyskinesia may occur during either chronic or initial treatment and with normal serum phenytoin levels. However, it occurs most often in patients on polytherapy, usually after increasing dosage and with toxic serum levels. Other signs of phenytoin intoxication may be present in these patients, but often the dyskinesia is the only side effect, which may delay the diagnosis and treatment. The clinical characteristics of the involuntary movements vary and may be focal or generalized, most often characterized by choreoathetosis and dyskinesias. These may last for hours, days or even years, but frequently disappear completely after phenytoin withdrawal.

Meningencefalites bacterianas agudas em crianças: complicações e sequelas neurológicas

We studied 271 children under age of 15 with diagnosis of acute bacterial meningencephalitis treated at Medical School in Ribeirão Preto, University of São Paulo, between 1980 and 1990. The patients were divided in two groups: 1) those who had not received previous antibiotics treatment (NTP), with 153 cases; and 2), those who had received previous antibiotics treatment (PT), with 118 cases. The etiological agent was more frequently identified in NPT group, while ventriculitis was more frequent in PT group. Mortality rate accounted for 19,5% of all cases, and 29.7% of children under 12 months of age. Acute meningitis caused by Streptococcus pneumoniae was frequently followed by increased mortality. Convulsive disorders and hemiparesis predominante among children under 12 months of age. On the neurosurgical point of view, ventriculitis, subdural hygroma, hydrocephalus, subdural empyema and brain abscess were identified and treated

Relação dose-dependente do uso crônico de fenitoína e atrofia cerebelar em pacientes com epilepsia

The chronic treatment with phenytoin or the acute intoxication by this drug may cause permanent cerebellar injury with atrophy of cerebellum vermis and hemispheres, which can be detected by neuroimaging studies. The aim of the present study was to investigate the correlation between the dosage and duration of treatment with phenytoin and the occurrence of cerebellar atrophy. Sixty-six patients were studied and had their tomographies analyzed for cerebellar atrophy. Of the 66 patients studied, 18 had moderate/severe atrophy, 15 had mild atrophy and 33 were considered to be normal. The patients with moderate/severe atrophy were those with higher exposure to phenytoin (longer duration of treatment and higher total dosage) showing statistically significant difference when compared to patients with mild atrophy or without atrophy (p=0.02). Further, the patients with moderate/severe atrophy had serum levels of phenytoin statistically higher than those of patients with mild atrophy or without atrophy (p = 0.008). There was no association between other antiepileptic drugs dosage or duration of treatment and degree of cerebellar atrophy. We also found that older patients had cerebellar atrophy more frequently, indicating that age or duration of the seizure disorder may also be important in the determination of cerebellar degeneration in these patients. We conclude that although there is a possibility that repeated seizures contribute to cerebellar damage, long term exposure to phenytoin, particularly in high doses and toxic serum levels, cause cerebellar atrophy.

Epilepsias parciais familiares

OBJECTIVE: To investigate the clinical and genetic characteristics of familial partial epilepsies. METHOD: Family history of seizures was questioned in all patients followed in our epilepsy clinics, from October 1997 to December 1998. Those with positive family history were further investigated and detailed pedigrees were obtained. All possibly affected individuals available underwent clinical evaluation. Seizures and epilepsy syndromes were classified according to the ILAE recommendations. Whenever possible, EEG and MRI were performed. RESULTS: Positive family history was identified in 32 unrelated patients. A total of 213 possibly affected individuals were identified, 161 of whom have been evaluated. The number of affected subjects per family ranged from two to 23. Temporal lobe epilepsy (TLE) was identified in 22 families (68%), frontal lobe epilepsy in one family (3%), partial epilepsy with centrotemporal spikes in five families (15%), and other benign partial epilepsies of childhood in four families (12%). Most of the affected individuals in the TLE families (69%) had clinical and/or EEG characteristics of typical TLE. However, the severity of epilepsy was variable, with 76% of patients with spontaneous seizure remission or good control with medication and 24% with refractory seizures, including 7 patients that underwent surgical treatment. In the other 10 families, we identified 39 possibly affected subjects, 23 of whom were evaluated. All had good seizure control (with or without medication) except for one patient with frontal lobe epilepsy. Pedigree analysis suggested autosomal dominant inheritance with incomplete penetrance in all families. CONCLUSION: Family history of seizures is frequent among patients with partial epilepsies. The majority of our families had TLE and its expression was not different from that observed in sporadic cases. The identification of genes involved in partial epilepsies may be usefull in classification of syndromes, to stablish prognosis and optimal treatment.

Síndrome de Rett: estudo retrospectivo e prospectivo de 28 pacientes

From November 1982 to May 1999, 28 children with Rett syndrome were followed-up for a medium period of 6 years and 2 months. Regression of developmental milestones started at the age between 5 and 20 months. Nineteen cases of typical Rett syndrome had uneventful pre and perinatal periods, loss of previously acquired purposeful hand skills, mental and motor regression and developed hand stereotypies; sixteen had head growth deceleration and 12 gait apraxia. Nine patients were atypical cases, 2 formes frustres, 2 congenital, 3 with early seizure onset, 1 preserved speech and 1 male. Epilepsy was present in 21 patients, predominantly partial seizures and the drug of choise was carbamazepine (15 patients). In the initial evaluation most patients were distributed on Stages II and III and on follow-up on Stages III and IV. Three children died.

Qualidade de vida em epilepsia e percepção de controle de crises

The individual affective-cognitive evaluations are important factors that control the way he feels the disease impact in his life. Then, the perception of seizure control is a more important factor to evaluate Quality of Life (QoL) than the illness characteristics, such as the severity, type, sickening period and seizure frequency. This study searched for the relationship among the subjective variables (perception of seizure control) and the illness characteristics to evaluate QoL. The sample consisted of 60 individuals with chronic epilepsy, aging 18 to 70 (M=37.05; SD=11.25), chosen at randon from the ambulatory of epilepsy - HC/UNICAMP, by the Questionnaire 65. The illness characteristics were not significant, except the seizures frequency, when associated to the impairment in QoL among controlled seizures and seizures with frequency higher than 10 per month (p=0.021). The perception of control was significantly associated to QoL (p=0.005).

Questionário de qualidade de vida na epilepsia: resultados preliminares

Seizures happen for brief periods of time, but the feelings of anxiety and helplessness, adaptation to the restrictions impose by the life-style and variety of other problems affect more the quality of life in epilepsy. This study proposes a protocol that regards the objectives of a quality of life assessment in health and is applied to a population that attends a university hospital. It contains 65 items and assesses the psychosocial performance, physical limitation, cognitive aspects, perception of control, self-concept, as well as perception of health and quality of life. The results of reliability and validity are discussed.
