Rett syndrome: retrospective and prospective study of 28 patients

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.No período entre Novembro 1982 e Maio 1999, 28 crianças com Síndrome de Rett foram seguidas por um período médio de 6 anos e 2 meses.O início da regressão do desenvolvimento psicomotor ocorreu entre 5 e 20 meses.Os 19 casos de síndrome de Rett típica apresentavam períodos pré e perinatal normais,e evoluíram com perda das habilidades previamente adquiridas, retardo psicomotor e estereotipias de mãos; 16 tinham desaceleração do crescimento craniano e 12 tinham marcha anormal. Nove pacientes foram casos atípicos: 2 formas frustras, 2 congênitas, 3 com crises precoces, 1 com fala preservada e 1 sendo do sexo masculino. A epilepsia esteve presente em 21 pacientes com crises predominantemente parciais e a droga de escolha foi a carbamazepina (15 pacientes). Na avaliação inicial a maioria dos pacientes estava distribuída em estágios II e III da síndrome e evolutivamente passaram aos estágios III e IV, sendo que 3 faleceram.40741

Cerebellar vermis hypoplasia - non progressive congenital ataxia: clinical and radiological findings in a pair of siblings

We describe the clinical and radiological findings of a pair of siblings with cerebellar vermis hypoplasia and compare them with the literature. Both of them present pregnancies and deliveries uneventful and both presented some grade of hypotonia, ataxia, ocular motor abnormalities and mild motor delay and slurred speech. These siblings meet many of the criteria described in non-progressive congenital ataxia in which can occur familial cases with cerebellar atrophy, including vermis hypoplasia. As differential diagnosis we compare them with related syndromes and with Joubert's syndrome which main radiological finding on MRI is vermis hypoplasia associated with "molar tooth" appearance. The correct answer for these cases will only be possible by molecular genetics

Encefalopatia hipertensiva associada a estado de mal epiléptico de repetição: relato de caso

Criança de cinco anos, feminina, branca, com história de oito internamentos nos últimos dois meses por crises convulsivas caracterizadas por vômitos, perda de consciência e clonias em hemicorpo direito. No exame físico, verificou-se hipertensão arterial grave (270/140 mmHg). Os estudos de neuroimagem (tomografia computadorizada e ressonância magnética) revelaram extensas áreas hipodensas, sugerindo edema cerebral. A arteriografia renal mostrou estenose da artéria renal direita, determinando a etiologia da hipertensão arterial. Com o controle da hipertensão, após a nefrectomia, houve reversão completa dos sintomas, assim como das anomalias de imagem

Learning disabilities: analysis of 69 children

With this article we intend to demonstrate the importance of evaluation and follow up of children with learning disabilities, through a multidisciplinary team. As well as to establish the need of intervention. We evaluate 69 children, from Aline Picheth Public School, in Curitiba, attending first or second grade of elementary school, through general and evolutionary neurological examination, pediatric checklist symptoms, and social, linguistic and psychological (WISC-III, Bender Infantile and WPPSI-figures) evaluation. The incidence was higher in boys (84,1%), familiar history of learning disabilities was found in 42%, and writing abnormalities in 56,5%. The most frequent diagnosis was attention deficit and hyperactivity disorder, in 39,1%. With this program, we aimed to reduce the retention taxes and stress the importance of this evaluation, and, if necessary, multidisciplinar intervention in the cases of learning disabilities

Imunoglobulina endovenosa em crianças com síndrome de Guillain-Barré Intravenous immunoglobulin in children with Guillain-Barré syndrome

Relatamos nossa experiência com imunoglobulina endovenosa (IGEV), plasmaferese e terapêutica de suporte no tratamento de 13 pacientes com síndrome de Guillain-Barré (SGB). Dos 13 pacientes, 7 receberam IGEV, 2 plasmaferese e 4 terapêutica de suporte. No 15° dia após a administração da IGEV, todos os pacientes deste grupo apresentaram melhora de pelo menos 1 grau na escala de Hughes et al. modificada. Dos 2 pacientes submetidos a plasmaferese, 1 apresentou melhora de 1 grau 5 dias após o procedimento. Entre os 4 pacientes que receberam tratamento de suporte, 2 apresentaram melhora dentro de 20 dias de evolução. No grupo que recebeu IGEV os escores finais foram menores e não houve recidivas. Assim, estes resultados sugerem que a IGEV diminui o tempo necessário para a melhora clínica quando comparado com tratamento suportivo.<br>We report our experience with intravenous immunoglobulin (IVIG), plasmapheresis and supportive care in 13 patients with the Guillain-Barré syndrome. Seven of 13 patients received IVIG, 2 plasmapheresis and 4 supportive care. At 15th day after IVIG administration, all patients in this group had improved at least one disability grade. In the plasmapheresis group, 1 improved at 5th day after the procedure. Two of the 4 patients that received supportive care improved at 20th day of evaluation. In the IVIG group, the final scores were lower and had no relapses. These results suggest faster clinical improvement with IVIG when compared with supportive measures

Síndrome de West: evolução clínica e eletrencefalográfica de 70 pacientes e resposta ao tratamento com hormônio adrenocorticotrófico, prednisona, vigabatrina, nitrazepam e ácido valpróico West syndrome: clinical and eletroencephalographic follow up of 70 patients and response to the adrenocorticotropic hormone, prednisone, vigabatrin, nitrazepam and valproate

Em estudo retrospectivo avaliamos a evolução clínica e eletrencefalográfica das formas criptogênica e sintomática da síndrome de West e analisamos a eficácia do hormônio adrenocorticotrófico, vigabatrina, prednisona, ácido valpróico e nitrazepam no controle dos espasmos. Participaram do estudo 70 pacientes, acompanhados por período maior que 2 anos. Doze (17%) eram criptogênicos e 58 (83%) sintomáticos. O grupo criptogênico apresentou percentagem significativamente maior de pacientes que frequentavam escola regular e desenvolvimento motor normal, melhor controle das crises epilépticas, tendência menor a evoluir para síndrome de Lennox Gastaut e 83,3% tiveram controle completo dos espasmos (72,4% dos pacientes do grupo sintomático obtiveram controle completo dos espasmos). O hormônio adrenocorticotrófico e a vigabatrina foram as drogas mais eficazes, controlando 68,75% e 60% dos espasmos, respectivamente, quando utilizados como droga de primeira escolha e 75% e 50%, respectivamente, como drogas de segunda escolha.<br>In a retrospective study we assessed the outcome of the criptogenic and symptomatic forms of West syndrome and evaluated the efficacy of adrenocorticotropic hormone, vigabatrin, prednisone, valproate and nitrazepam in the spasms control. Seventy patients were follwed up by 2 years. Twelve (17%) were criptogenics and 58 (83%) symptomatics. In criptogenic group significantly more patients were in regular school classes and with normal motor development, better control of seizure, less tendency to evoluate to Lennox Gastaut syndrome and 83.3% had control of spasms (72.4% of patients from symptomatic group had control of spasms). Adrenocorticotropic hormone and vigabatrin were the most efective drugs, with 68.75% and 60% of spasms control, respectivelly, when used as first line of therapy and 75% and 50%, respectivelly, as second line of therapy
