Efectividad del uso de seating de posicionamiento en niños con parálisis cerebral discinética: revisión sistemática / Effectiveness of the use of seating devices in children with dyskinetic cerebral palsy: a systematic reviewx

Introduction: To assess the effectiveness of seating devices during the sitting position on postural stability and upper limb functionality in users with dyskinetic type cerebral palsy. Method: A systematic review that included randomized, quasi-randomized, cohort, and pre-post intervention clinical trials with evaluation before and after the intervention. This review included studies of chil-dren with a diagnosis of cerebral palsy, mainly of the dyskinetic type, with ages between 2 and 10 years old. The databases of CINAHL Plus, Cochrane (Central), EMBASE (Via Ovid), Virtual Health Library, OT Seeker, Medline (Via PubMed) and OpenGrey were used. Results: Two studies met the inclusion criteria; however, the analysis was carried out qualitatively due to the methodological quality for these, with presence of a high risk of bias. The study by Cimolin described greater trunk stability and smooth upper extremity movements with the use of a dynamically configured seat. Nwaobi described better upper extre-mity functionality in a seat inclined at 0º and 30º, not referring to trunk stability. Conclusion: From the review of the results it is concluded that there is not enough scientific evidence to determine that the use of seating devices favors the postural control and the functionality of upper extremities in children with cerebral dyskinesia type cerebral palsy.

Introducción: Evaluar la eficacia del posicionamiento sedente en la estabilidad postural y funcionalidad de extremidades superiores, en ni-ños con parálisis cerebral discinética, comparando el uso y el no uso de seating de posicionamiento. Método: Revisión siste-mática incluyendo ensayos clínicos de tipo aleatorio, cuasialeatorizado, de cohorte y casos con evaluación antes y después de la intervención. Se incluyó niños con parálisis cerebral discinético, entre 2 y 10 años de edad. Se utilizó bases de datos de CI-NAHL Plus, Cochrane (Central), EMBASE (Vía Ovid), Biblioteca Virtual de la Salud, OT Seeker, Medline (Via PubMed) y Open Grey. Resultados: Dos estudios cumplieron criterios de inclusión, aunque el análisis se realizó de forma cualitativa por la calidad metodológica de estos. Cimolin detectó mayor estabilidad de tronco y suavidad en los movimientos de extremidades superiores con el uso de un asiento de configuración dinámica. Nwaobi describió mejor funcionalidad de extremidad superior en un asiento inclinado a 0º y 30º, no haciendo referencia a la estabilidad de tronco. Conclusión: De la revisión de los resulta-dos, se concluye que no existe evidencia científica suficiente que determine que el uso de seating favorezca o no el control postural y la funcionalidad de extremidades superiores en niños y jóvenes con parálisis cerebral de tipo discinética.

Factors associated with bruxism in children with developmental disabilities

The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD), mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78) greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02) greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24) greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.

Executive dysfunction and motor symptoms in Parkinson's disease / Disfunções executivas e sintomas motores na doença de Parkinson

The aim of this study is to analyze executive function and motor symptoms in patients with idiopathic Parkinson's disease (PD). The sample consisted of 44 subjects with PD between the ages of 45 to 75, who were examined consecutively. The subjects were divided into two groups according to the duration of the disease. The control group was composed of spouses, family and accompanying members. Patients included were submitted to motor dysfunction evaluation using the UPDRS. The executive functions modalities analyzed included: operational memory, inhibitory control, planning, cognitive flexibility and inductive reasoning. Significant differences between the experimental and control groups were found in all the executive domains studied. Evidence of tremor, rigidity and bradykinesia correlation with executive dysfunction were not observed. Patients with PD, even in the initial phase of the disease, presented executive dysfunction. The cardinal motor signs of the disease were not correlated with the cognitive dysfunction found.

O objetivo do estudo é avaliar as funções executivas e sintomas motores em pacientes portadores de doença de Parkinson. A amostra se constituiu de 44 portadores de doença de Parkinson com idade entre 45 e 75 anos, examinados consecutivamente, os quais foram divididos em dois grupos de acordo com o tempo de duração da doença. O grupo controle foi composto de acompanhantes ou cônjuges. Os sujeitos selecionados foram submetidos à avaliação motora utilizando-se a escala UPDRS e à avaliação das funções executivas nas modalidades: raciocínio indutivo, memória operacional, controle inibitório, planejamento e flexibilidade cognitiva. Os resultados apontaram diferenças significantes entre os grupos experimentais e controle nas modalidades analisadas. Não encontramos evidência de associação entre tremor, rigidez e bradicinesia com as funções executivas. Conclui-se que os pacientes com doença de Parkinson, mesmo nas fases iniciais da doença, apresentam comprometimento cognitivo executivo. Os sintomas motores da doença não estavam correlacionados às disfunções executivas.

Classification of cerebral palsy: association between gender, age, motor type, topography and Gross Motor Function / Classificação da paralisia cerebral: associação entre gênero, idade, tipo motor, topografia e Função Motora Grossa

The goal of this study was to assess the relation between gender, age, motor type, topography and gross motor function, based on the Gross Motor Function System of children with cerebral palsy. Trunk control, postural changes and gait of one hundred children between 5 months and 12 years old, were evaluated. There were no significant differences between gender and age groups (p=0.887) or between gender and motor type (p=0.731). In relation to body topography most children (88 percent) were spastic quadriplegic. Most hemiplegics children were rated in motor level I, children with diplegia were rated in motor level III, and quadriplegic children were rated in motor level V. Functional classification is necessary to understand the differences in cerebral palsy and to have the best therapeutic planning since it is a complex disease which depends on several factors.

Este estudo teve como objetivo avaliar a relação entre gênero, idade, tipo motor, topografia e Função Motora Grossa, baseado no Sistema de Função Motora Grossa em crianças com paralisia cerebral. Participaram desta pesquisa 100 crianças com idade entre 5 meses a 12 anos que foram observadas em relação ao controle de tronco, trocas posturais e marcha. Não houve diferenças significativas entre gêneros e grupos etários (p=0,887) e entre gênero e tipo motor (p=0,731). Em relação à topografia corporal, houve predomínio de crianças com quadriplegia, sendo que a maioria (88 por cento) era do tipo espástico. Quanto ao nível motor, as crianças hemiplégicas pertenciam em sua maioria ao nível I, as diplégicas ao nível III e as quadriplégicas ao nível V. Sendo a paralisia cerebral uma condição complexa que depende de diversos fatores, beneficia-se de classificações funcionais para compreensão da diversidade e melhor planejamento terapêutico.

Síndrome Tako-Tsubo (Discinesia antero-apical transitoria): Primer caso descrito en América Latina y revisión de la literatura / Tako-Tsubo syndrome (transient antero-apical dyskinesia): first case reported in Latin America and review of the literature

El síndrome Tako-Tsubo es una entidad clínica de reciente descripción que simula un infarto agudo del miocardio. Comprende la asociación de dolor precordial con elevación de ST-T en derivaciones precordiales en ausencia de la oclusión de alguna arteria coronaria y con una deformación típica y reversible del ventrículo izquierdo como consecuencia de discinesia anteroapical con hipercinesia basal. Afecta predominantemente al sexo femenino y en una revisión de 2001 se refiere que sólo dos casos habían sido reportados en pacientes no japoneses. Presentamos un caso típico de síndrome Tako-Tsubo recurrente y desencadenado por estrés emotivo. Este es el primer caso informado de Latinoamérica, el que se complementa con una revisión actualizada de la literatura. Esta última sugiere que el síndrome Tako-Tsubo es más frecuente de lo sospechado, pero suele pasar desapercibido. Es importante reconocer este síndrome ya que su manejo y pronóstico es diferente al del infarto agudo del miocardio que resulta de la oclusión trombótica de una placa ateroesclerosa coronaria.

Tako-Tsubo syndrome (TTS) is a recently described entity that can mimic an acute myocardial infarction. It is characterized by anginal chest pain with ST-T elevation in precordial leads, no coronary obstruction on angiography, and as its distinctive feature, a reversible left ventricular antero-apical ballooning with basal hyperkinesis. TTS is more frequent in female and elderly patients and in an article published in 2001 it was mentioned that only two cases had been reported outside Japan. We describe a typical case of recurrent TTS triggered by intense emotional stress. This is the first case reported from Latin America. A review of the literature suggests that TTS is more frequent than previously thought but apparently due to lack of awareness of this entity it can go unrecognized. Identification of TTS is of clinical importance because its management and prognosis differs significantly from that of an acute myocardial infarction that results from the thrombotic occlusion of a coronary atherosclerotic plaque.

Functional MR imaging of hand motor cortex in a case of persistent mirror movement.

Persistent mirror movements are unwanted movements restricted to muscles homologous to those moved intentionally on the opposite body half. It is rarely observed and the functional MRI findings in a case of persistent mirror movement are described.
