BACKGROUND: The Manual Ability Classification System (MACS) has been widely used to describe the manual ability of children with cerebral palsy (CP); however its reliability has not been verified in Brazil. OBJECTIVE: To establish the inter- and intra-rater reliability of the Portuguese-Brazil version of the MACS by comparing the classifications given by therapists and parents of children with CP. METHOD: Data were obtained from 90 children with CP between the ages of 4 and 18 years, who were treated at the neurology and rehabilitation clinics of a Brazilian hospital. Therapists (an occupational therapist and a student) classified manual ability (MACS) through direct observation and information provided by parents. Therapists and parents used the Portuguese-Brazil version of the MACS. Intra- and inter-rater reliability was obtained using unweighted Kappa coefficient (k) and intra-class correlation coefficient (ICC). The Chi-square test was used to identify the predominance of disagreements in the classification of parents and therapists. RESULTS: An almost perfect agreement resulted among therapists [K=0.90 (95% CI 0.83-0.97); ICC=0.97 (95%CI 0.96-0.98)], as well as with intra-rater (therapists), with Kappa ranging between 0.83 and 0.95 and ICC between 0.96 and 0.99 for the evaluator with more and less experience in rehabilitation, respectively. The agreement between therapists and parents was fair [K=0.36 (95% CI 0.22-0.50); ICC=0.79 (95% CI 0.70-0.86)]. CONCLUSIONS: The Portuguese version of the MACS is a reliable instrument to be used jointly by parents and therapists.
BACKGROUND: Several studies have demonstrated the importance of using the Gross Motor Function Classification System (GMFCS) to classify gross motor function in children with cerebral palsy, but the reliability of the expanded and revised version has not been examined in Brazil (GMFCS E & R). OBJECTIVE:: To determine the intra- and inter-rater reliability of the Portuguese-Brazil version of the GMFCS E & R applied by therapists and compare to classification provided by parents of children with cerebral palsy. METHOD: Data were obtained from 90 children with cerebral palsy, aged 4 to 18 years old, attending the neurology or rehabilitation service of a Brazilian hospital. Therapists classified the children's motor function using the GMFCS E & R and parents used the Brazilian Portuguese version of the GMFCS Family Report Questionnaire. Intra- and inter-rater reliability was obtained through percentage agreement and Cohen's unweighted Kappa statistics (k). The Chi-square test was used to identify significant differences in the classification of parents and therapists. RESULTS: Almost perfect agreement was reached between the therapists [K=0.90 (95% confidence interval 0.83-0.97)] and intra-raters (therapists) with K=1.00 [95% confidence interval (1.00-1.00)], p<0.001. Agreement between therapists and parents was substantial (k=0.716, confidence interval 0.596-0.836), though parents classify gross motor impairment more severely than therapists (p=0.04). CONCLUSIONS: The Portuguese version of the GMFCS E & R is reliable for use by parents and therapists. Parents tend to classify their children's limitations more severely, because they know their performance in different environments.
OBJETIVO: o objetivo deste trabalho foi o de verificar a prevalência das acidúrias orgânicas em pacientes brasileiros de alto risco. MÉTODOS: técnicas laboratoriais para a detecção e quantificação de ácidos orgânicos por cromatografia gasosa acoplada à espectrometria de massa foram implantadas em Porto Alegre, Brasil. Foram analisados 1.480 pacientes suspeitos, investigados entre janeiro de 1994 e junho de 2000. RESULTADOS: foram diagnosticados 73 (4,9%) casos de acidemias (acidúrias) orgânicas entre os indivíduos testados. Na maioria desses pacientes a terapia resultou em rápida melhora na sua sintomatologia, distintamente de nossos casos previamente diagnosticados em outros laboratórios na Europa e nos Estados Unidos, quando muitos pacientes faleciam antes que quaisquer medidas pudessem ser tomadas. CONCLUSÕES: estes resultados mostram a importância de diagnosticar as acidúrias orgânicas in loco mesmo em países em desenvolvimento, apesar dos custos extras envolvidos.
OBJECTIVE: to determine the prevalence of organic acidurias in high-risk Brazilian patients. METHODS: laboratory techniques for the detection and quantification of organic acids by gas chromatography/mass spectrometry were implemented in Porto Alegre, Brazil. We investigated 1,480 patients suspected of organic aciduria between January 1994 and June 2000. RESULTS: seventy three (4.9%) cases of organic acidemias (acidurias) were diagnosed among the tested individuals. In most of these patients, prompt therapy resulted in rapid symptom improvement; these results are completely different from our previous cases diagnosed in other laboratories in Europe and the United States, where several patients died before any measures could be taken. CONCLUSIONS: these results demonstrate the importance of diagnosing organic acidurias in loco even in developing countries, in spite of the extra costs involved.
Noventa e quatro recém-nascidos com encefalopatia hipóxico-isquêmica (EHI), atendidos no Hospital das Clínicas de Ribeirão Preto desde 1982, foram avaliados evolutivamente na fase aguda e por período médio de 47 meses. De 43 casos com EHI 1,40 se recuperaram em 96 horas e 3 faleceram. Dos 40 com EHI II, 37,5% se recuperaram até o sétimo dia e demais permaneceram com alterações. Os 11 casos com grau III faleceram até o segundo mês de vida. As crianças com EHI grau I não apresentaram seqüelas motoras. Do grupo com EHI grau II 34,5% apresentaram paralisia cerebral e 17,7% atraso neuromotor. 80% dos casos com sequela apresentaram exame neurológico anormal além do sétimo dia, na fase aguda da EHI. Epilepsia ocorreu em 17,5% dos casos com EHI grau II e somente no grupo com seqüelas motoras. Teste de QI não evidenciou diferença significativa entre os grupos com grau I, II sem seqüelas motoras e o grupo controle. Com esses dados os autores reafirmaram a importância prognostica da evolução da EHI na fase aguda.
Ninety four neonates with hypoxic ischemic encephalopathy HIE attended at the University of Ribeirão Preto since 1982 were studied in terms of the neurological alterations during the acute phase and outcome over a mean period of 47 months. From 43 newborns with HIE I, 40 recovered within 96 hours and 3 died. Among 40 infants with HIE II, 37.5% recovered within the first week, and the others continued abnormal beyond the 7th day. All 11 infants with HIE III died before the second month of life. The HIE I group had no motor sequelae. Among the HIE II group, 34.5% showed cerebral palsy and 17.7% neuromotor retardation. 80.0% of those with sequelae persisted abnormal beyond 7th day of life, during the acute phase of the HIE. Epilepsy occurred in 17.5% of cases with HIE grade II, only among those with neuromotor sequelae. The 1Q test did not show statistically significant difference between the HIE I, II without motor sequelae and the control groups. The authors reaffirm the value of the findings in the acute phase of HIE on the outcome of these patients.
Um caso raro de meningite recorrente devido a meningocele sacral anterior e agenesia das vértebras sacras coccígeas é descrito. Herança autossômica dominante para malformação medular caudal é demonstrada e, possíveis fatores ambientais (ligados ao cromo), são discutidos.
A rare case of recurrent meningitis due to congenital anterior sacral meningocele and agenesis of the sacral and coccygeal vertebrae is described. An autosomal dominant inheritance is demonstrated for lower cord malformation, and environmental factors (chromic acid or fumes) are discussed.
Os autores apresentam sua experiência em 102 crianças com hidrocefalia de diversas etiologias, acompanhadas por 5 1/2 anos. Cerca de 80% dessas crianças tinham idade inferior a dois anos, o que possibilitou seu acompanhamento com a ultra-sonografia craniana (4,4 exames por paciente). Os resultados a longo prazo são comparáveis aos obtidos na literatura com redação ao número de procedimentos por paciente (1,66), índice de infecqões (5,2%), mortalidade (6,8%) e desenvolvimento intelectual. A ultra-sonografia mostrou-se útil porque é inócua, tem baixo custo operacional, é comparável à tomografia computadorizada nessa faixa etária, podendo ser repetida rotineiramente e permitindo um relacionamento entre o médico, a criança e sua mãe que afetam favoravelmente o diagnóstico precoce de complicações e a melhor compreensão da patologia pelos pais.
A personal series (in 94% of the cases) of 102 children who underwent 170 procedures (1.66 procedures/patient) for hydrocephalus has been followed for 5 1/2 years (Jan-S3 to Jun-88). Most of the children were under two years of age (80%) and in these cases brain sonography was the examination of choice for both diagnosis and follow-up (307 examinations, 4.4 per patient). Only occasionally was computed tomography necessary for better study in these cases. Our results suggest that there was no significant difference between our cases and those published in the litterature concerning the number of procedures/patient (1.66)., infection rate (5.2%), mortality rate (6.8%) and intellectual performance. We recommend the use of brain sonography both in diagnosis and follow-up studies for hydrocephalic children since this examination is innocuous, inexpensive and easy to perform by neurosurgeons. Also it provides a good interaction between the examiner, the child and the parents, which is of utmost importance for the comprehension of the disease by the parents and early diagnosis of complications by the neurosurgeon.
