ABSTRACT

OBJECTIVE: This work aimed to evaluate and correlate symptoms, biochemical blood test results and single nucleotide polymorphisms for lactose intolerance diagnosis. METHOD: A cross-sectional study was conducted in Fortaleza, Ceará, Brazil, with a total of 119 patients, 54 of whom were lactose intolerant. Clinical evaluation and biochemical blood tests were conducted after lactose ingestion and blood samples were collected for genotyping evaluation. In particular, the single nucleotide polymorphisms C>T-13910 and G>A-22018 were analyzed by restriction fragment length polymorphism/polymerase chain reaction and validated by DNA sequencing. RESULTS: Lactose-intolerant patients presented with more symptoms of flatulence (81.4%), bloating (68.5%), borborygmus (59.3%) and diarrhea (46.3%) compared with non-lactose-intolerant patients (p<0.05). We observed a significant association between the presence of the alleles T-13910 and A-22018 and the lactose-tolerant phenotype (p<0.05). After evaluation of the biochemical blood test results for lactose, we found that the most effective cutoff for glucose levels obtained for lactose malabsorbers was <15 mg/dL, presenting an area under the receiver operating characteristic curve greater than 80.3%, with satisfactory values for sensitivity and specificity. CONCLUSIONS: These data corroborate the association of these single nucleotide polymorphisms (C>T-13910 and G>A-22018) with lactose tolerance in this population and suggest clinical management for patients with lactose intolerance that considers single nucleotide polymorphism detection and a change in the biochemical blood test cutoff from <25 mg/dL to <15 mg/dL.

ABSTRACT

OBJETIVO: Avaliar a repetibilidade das medidas dos parâmetros espaço-temporais da marcha por meio de um estudo comparativo entre crianças normais e crianças com paralisia cerebral (PC). MÉTODOS: A amostra foi composta por 17 crianças divididas em dois grupos: um grupo de nove crianças com PC do tipo hemiplegia espástica e um grupo com oito crianças normais que foram avaliadas pelo mesmo pesquisador em duas sessões diferentes, com intervalo de uma semana entre as sessões. As crianças caminharam em velocidade autosselecionada e foram utilizadas seis tentativas nas sessões 1 e 2 para representar a média. Para registro dos parâmetros espaço-temporais, foi utilizado o sistema Peak Motus, com duas câmeras de vídeo SVHS com taxa de aquisição de 60 Hz. Coeficiente de correlação intraclasse (ICC) e limites de concordância de Bland-Altman foram escolhidos para análise dos dados. RESULTADOS: Os resultados demonstraram que as crianças com PC apresentaram menor velocidade e comprimento do ciclo do que as crianças normais para as sessões 1 e 2. Para todos os parâmetros espaço-temporais, os dois grupos apresentaram valores de ICC de excelentes a moderados, ou seja, maior do que 0,70. CONCLUSÃO: Pode-se concluir que os dois grupos apresentaram níveis bons de repetibilidade para todos os parâmetros analisados quando seis tentativas foram utilizadas para representar a média.


OBJECTIVE: To evaluate the repeatability of spatiotemporal gait parameters by means of a comparative study between normal children and children with cerebral palsy (CP). METHODS: The sample consisted of 17 children divided into two groups: a group of nine children with spastic hemiplegia CP and a group of eight normal children. The children were evaluated by the same researcher in two different sessions, with a one-week interval between the sessions. The children walked at self-selected velocities, and six attempts were performed at each session to represent the average. To record the spatiotemporal parameters, the Peak Motus system was used with two SVHS video cameras with an acquisition rate of 60 Hz. The intra-class correlation coefficient (ICC) and Bland-Altman concordance limits were chosen for data analysis. RESULTS: The results demonstrated that the children with CP presented lower velocity and shorter cycles than the normal children in sessions 1 and 2. For all the spatiotemporal parameters, the two groups presented moderate to excellent ICC values, i.e. greater than 0.70. CONCLUSION: It can be concluded that the two groups presented good levels of repeatability for all the parameters analyzed when six attempts were used to represent the average.

ABSTRACT

OBJETIVO: Este estudo teve como objetivo descrever variáveis espaço-temporais da marcha de crianças de 4 a 5 anos de idade com paralisia cerebral (PC) do tipo hemiplegia espástica, antes e após sessões de eletroestimulação do músculo tibial anterior do dimídio plégico. METODOLOGIA: Cinco crianças foram submetidas à eletroestimulação durante 12 sessões (três vezes na semana). Para a coleta dos dados biomecânicos, foi realizada análise da marcha através do sistema Peak Motus versão 7.0 com duas câmeras de vídeo SVHS com taxa de aquisição de 60 Hz. Para reconstrução tridimensional dos movimentos, foi utilizado o método Direct Linear Trasformation (DLT). RESULTADOS: Após a intervenção, todas as crianças apresentaram diferenças menores entre o comprimento dos passos do dimídio plégico e não-plégico (p= 0,009). Observou-se o aumento no comprimento do ciclo em quatro crianças. Duas crianças tiveram aumento da cadência, velocidade e tempo de apoio simples do dimídio plégico. CONCLUSÕES: Foi verificada a melhoria da simetria da marcha relacionada ao comprimento do passo antes e após a intervenção, embora o aumento nas variáveis espaço-temporais não tenha ocorrido da mesma maneira para todas as crianças. Apesar das dificuldades em se obterem amostras maiores e mais homogêneas em estudos desse tipo, os dados sugerem a necessidade de identificação e maior controle das variáveis intervenientes no tratamento e na marcha de crianças portadoras de paralisia cerebral.


OBJECTIVE: This study had the objective of describing spatiotemporal gait variables of four to five-year-old children with spastic hemiplegic cerebral palsy, before and after sessions of electrostimulation of the anterior tibial muscle on the paralyzed side. METHOD: Five children underwent 12 sessions of electrostimulation (three times a week). To collect biomechanical data, the gait was analyzed using the Peak Motus system, version 7.0, with two S-VHS video cameras with an acquisition rate of 60 Hz. Three-dimensional reconstruction of the movements was performed using the direct linear transformation (DLT) method. RESULTS: Following the intervention, all the children presented smaller differences in step length between the paralyzed and non-paralyzed sides (p= 0.009). Four children presented increased cycle amplitude. Two children presented increased cadence, speed and single support time on the paralyzed side. Thus, it was found that there was an improvement in gait symmetry in relation to the step lengths seen before and after the intervention, although the increase in the spatiotemporal variables did not occur in the same way for all the children. CONCLUSION: Despite the difficulties in defining larger and more homogeneous samples for studies of this type, the present data suggest the need for identification of and greater control over the variables that affect gait and its treatment among children with cerebral palsy.
