Adaptação de uma Escala de Avaliação de Anomalias Perceptuais para o Brasil / Adaptation a Scale of Evaluation of Perceptual Anomalies for Brazil / Adaptación de una Escala de Evaluación de Anomalías Perceptuales para Brasil

Resumo O objetivo desta pesquisa foi adaptar a Structured Interview for Assessing Perceptual Anomalies (SIAPA) para o Brasil para ser utilizada como instrumento de autorrelato. Utilizou-se uma amostra não probabilística de 854 universitários, a maioria do sexo masculino (51,4 %) e com idades entre 16 e 65 anos (M = 23,7; DP = 6,8). Após a tradução e validação semântica da SIAPA, testaram-se os parâmetros de validade e precisão por meio de análises fatoriais, coeficientes alfa de Cronbach e análises via Teoria de Resposta ao Item (TRI). Os resultados confirmaram a adequação psicométrica da medida, apontando uma solução unidimensional com altas cargas no fator geral e alta consistência interna (α = 0,88; Ω = 0,88). Acredita-se que o objetivo proposto tenha sido satisfeito, de modo que, ao final da pesquisa, contou-se com uma medida válida e fidedigna que pode ser utilizada, tanto para rastreio quanto para pesquisa, para compreender e diagnosticar anomalias perceptuais.

Abstract The purpose of this research was to adapt the Structured Interview for Assessing Perceptual Anomalies (SIAPA) for use in Brazil as a self-report tool. A non-probabilistic sample of 854 undergraduate students was used, mostly men (51.4%) and aged between 16 and 65 years (M = 23.7, SD = 6.8). After the translation and semantic validation of SIAPA, the validity and precision parameters were tested by means of factor analysis, Cronbach's alpha coefficients, and Item Response Theory (IRT) analysis. The results confirmed the psychometric adequacy of the measure, pointing to a one-dimensional solution with high loads on the general factor and high accuracy (α = 0.88; Ω = 0.88). It is believed that the proposed objective was satisfied, so that at the end of the investigation there was a valid and reliable measure that can be used, both for screening and research, to understand and diagnose perceptual anomalies.

Consideraciones sobre las condiciones neuropsiquiátricas del Quijote de la Mancha / Considerations about the Neuropsychiatry Conditions of Quixote of La Mancha

RESUMEN Don Quijote de la Mancha, el pintoresco personaje creado por Miguel de Cervantes Saavedra en su obra inmortal El Ingenioso Hidalgo Don Quijote de la Mancha, presenta varias condiciones neuropsiquiátricas que incluyen tremor, trastornos del sueño, síntomas neuropsiquiátricos, síncope, trastornos de la percepción y traumatismo craneoencefálico. A lo largo de la obra, se presentan episodios en los que se hacen evidentes los diferentes trastornos mencionados. El artículo hace un recuento de ellos a través de la novela y un análisis a la luz de los conocimientos actuales sobre dichas condiciones.

ABSTRACT Don Quixote of La Mancha, the picturesque character created by Miguel de Cervantes Saavedra in his immortal book The Ingenious Nobleman Sir Quixote of La Mancha, presents several neuropsychiatric conditions, including tremor, sleep disturbances, neuropsychiatric symptoms, syncope, perception disorders and traumatic brain injury. Throughout the masterpiece, there are episodes where the aforementioned disorders are evident. This paper makes a list of them and analyses them in the light of the current knowledge of those conditions.

Norm scores of cancelation and bisection tests for unilateral spatial neglect: data from a Brazilian population

OBJECTIVE: Unilateral spatial neglect (USN) results in a consistent and exaggerated spatial asymmetry in the processing of information about the body or space due to an acquired brain injury. There are several USN tests for clinical diagnosis, but none of them are validated in Brazil. The aim was to obtain normative values from a healthy sample in Brazil and to evaluate the effects of demographic variables on USN tests. METHODS: This was a cross-sectional study performed with 150 neurologically healthy individuals. USN was evaluated using the line cancelation (LC), star cancelation (SC), and line bisection (LB) tests in the A3 (29.7 x 42.0 cm) sheet format. RESULTS: In LC, 143 participants had 0 omissions, and the occurrence of failure was significantly associated with aging (OR=1.1[1.02-1.2]; p=0.012). In SC, 145 participants had fewer than 1 omission, and the occurrence of failure was significantly associated with aging (OR=1.07[1.03-1.11]; p<0.001). In LB, deviations were the lowest for those with the highest level of education (r=0.20; p=0.015), and the deviation was 9.5 mm. CONCLUSION: The cutoff points presented in this study may be indicative of USN, but due to performance differences based on age, we suggest using different norm scores for different age groups. These norm scores can be used in the clinic immediately for USN diagnosis.

Validation of the Catherine Bergego Scale in patients with unilateral spatial neglect after stroke / Validação da Escala Catherine Bergego em pacientes com negligência espacial unilateral após acidente vascular cerebral

ABSTRACT: The Catherine Bergego Scale (CBS) is a scale to evaluates the impact of unilateral spatial neglect (USN) on everyday life of patients after stroke. Objective: The aim of this study was to evaluate the reliability and comprehension of the Portuguese version of the CBS for patients with USN after stroke. Methods: This was a cross-sectional study in patients with stroke and USN. The CBS was translated, culturally adapted and applied by two independent investigators. The patients were also evaluated by the Behavioural Inattention Test (BIT), NIHSS, mRS and Barthel scale to assess USN severity, neurological function, disability and autonomy consecutively. Consistency and coherence were analysed using Cronbach's α, inter-observer reliability by Kappa, and the correlation between the CBS, BIT, NIHSS, mRS, and Barthel was determined using Pearson correlation. Results: Twenty-two patients were evaluated and the observed Cronbach's α=0.913. For intra-observer reproducibility, the 10 items showed a reasonable and high reliability between evaluators. The CBS showed a negative correlation with the BIT. There was a low correlation between the BIT and NIHSS, mRS and Barthel index. Conclusion: The CBS is an adequate and validated scale for assessing patients with USN after stroke in a Brazilian population.

RESUMO: A Escala de Catherine Bergego (CBS) é uma escala para avaliar o impacto da negligência espacial unilateral (USN) no cotidiano de pacientes após AVC. Objetivo: Não há validação da CBS para população brasileira e o objetivo deste estudo foi avaliar a confiabilidade e compreensão da versão em português da CBS para pacientes com USN após AVC. Métodos: Trata-se de um estudo transversal em pacientes com AVC e USN. A CBS foi traduzida, adaptada culturalmente e aplicada por dois investigadores independentes. Os pacientes também foram avaliados pelo Behaviour Innatention Test (BIT), NIHSS, mRS e Barthel para avaliar a gravidade da USN, função neurológica, incapacidade e autonomia consecutivamente. A consistência e a coerência foram analisadas pelo coeficiente α de Cronbach, a confiabilidade interobservador foi avaliada pelo coeficiente kappa e a correlação entre o CBS, BIT, NIHSS, mRS e Barthel foi avaliada pela correlação de Pearson. Resultados: Vinte e dois pacientes foram avaliados e observaram-se consistência e coerência pelo coeficiente α de Cronbach=0,913. Na análise da reprodutibilidade intraobservador, os 10 itens da escala apresentaram confiabilidade razoável e alta entre os avaliadores. O CBS mostrou correlação negativa com o BIT. Houve baixa correlação entre BIT e NIHSS, mRS e índice de Barthel. Conclusão: A CBS é uma escala adequada e validada para avaliar pacientes com USN após AVC em uma população brasileira e de língua portuguesa.

Fatores associados a alteração da percepção sensorial tátil nos pés de pacientes com diabetes mellitus / Facrors associated with altered tactile sensory perception in the feet of patients with diabetes mellitus

A alteração na percepção sensorial tátil é a complicação neurológica e microvascular mais prevalente da diabetes mellitus, sendo frequentemente subnotificada e subtratada, o que pode levar a um aumento no risco de morbidade e mortalidade. É um problema que antecede a neuropatia diabética, uma das principais causas de ulcerações e amputações. O objetivo deste estudo foi analisar sinais, sintomas e fatores etiológicos da alteração da percepção sensoril tátil em pacientes com diabetes mellitus. Foi conduzido estudo metodológico em duas etapas: revisão integrativa da literatura e validação clínica com estudo transversal de abordagem quantitativa. A revisão integrativa da literatura foi realizada no período de agosto a setembro de 2016, nas principais bases de dados nacionais e internacionais, utilizando os descritores: neuropatias diabéticas, tato, percepção tátil, transtornos da percepção, distúrbios somatossensoriais e enfermagem. De 1371 publicações identificadas, obteve-se uma amostra de 23 estudos que subsidiaram, com as variáveis pertinentes, o instrumento de coleta de dados da etapa clínica. As publicações ocorreram entre 1992 e 2015, com maior produção nos Estados Unidos, com 17,3%. Os estudos (56,5%) foram do tipo transversal, prevalecendo nível de evidência IV (56,5%). A pesquisa clínica foi desenvolvida no ambulatório de endocrinologia do hospital de referência no Município de Campina Grande/PB, no período de maio a outubro de 2017. Foi realizado estudo piloto para determinar a confiabilidade entre avaliadores na coleta de dados utilizando na análise o coeficiente Kappa. O instrumento de coleta de dados continha aspectos sociodemográficos, dados clínicos gerais, a história clínica do diabetes mellitus e avaliação clínica dos pés através de teste do monofilamento de Semmes-Weinstein, teste de sensibilidade dolorosa, teste de sensibilidade vibratória com o diapasão e reflexo aquileu. Foram incluídos no estudo 224 pacientes. A prevalência global de alteração da percepção sensorial tátil foi de 53,1%. Na análise multivariada foi identificado que sexo feminino (p=0,019), diabetes mellitus tipo 2 (p=0,002), úlcera prévia (p=0,001), sensação de queimação (p=0,003), rachaduras e fissuras (p=0,017), calosidades (p=0,033) e pé de Charcot (p=0,019) foram associados à presença de alteração da percepção sensorial tátil. Constatou-se uma alta prevalência de alteração na percepção sensorial tátil entre os diabéticos. A identificação precoce de sinais, sintomas e fatores etiológicos podem subsidiar o enfermeiro no planejamento de intervenções baseadas em evidência na prevenção de ulcerações e amputações futuras.(AU)

The change in tactile sensory perception is the most prevalent neurological and microvascular complication of diabetes mellitus, often under-reported and under-treated, which may lead to an increased risk of morbidity and mortality. It is a problem that predates diabetic neuropathy, a major cause of ulceration and amputation. The objective of this study was to analyze the signs, symptoms and etiological factors of altered tactile sensory perception in patients with diabetes mellitus. A methodological study was conducted in two stages: integrative literature review and clinical validation with a cross - sectional quantitative approach. The integrative literature review was carried out from August to September 2016, in the main national and international databases, using the descriptors: diabetic neuropathies, touch, tactile perception, perceptual disorders, somatosensory disorders and nursing. Of 1371 publications identified, a sample of 23 studies was obtained that subsidized, with the pertinent variables, the instrument of data collection of the clinical stage. The publications occurred between 1992 and 2015, with higher production in the United States, with 17.3%. The studies (56.5%) were of the transverse type, with a level of evidence IV (56.5%). The clinical research was carried out in the endocrinology outpatient clinic of the reference hospital in the city of Campina Grande / PB, from May to October 2017. A pilot study was conducted to determine the reliability among raters in the data collection using the Kappa coefficient . The data collection instrument contained sociodemographic aspects, general clinical data, clinical history of diabetes mellitus and clinical evaluation of the feet through the Semmes-Weinstein monofilament test, pain sensitivity test, vibration sensitivity test with tuning fork, and aquileu reflex . A total of 224 patients were included in the study. The overall prevalence of altered tactile sensory perception was 53.1%. In the multivariate analysis, the female gender (p = 0.019), type 2 diabetes mellitus (p = 0.002), previous ulcer (p = 0.001), burning sensation (p = 0.003), cracks and fissures (p = 0.033) and Charcot's foot (p = 0.019) were associated with the presence of altered tactile sensory perception. There was a high prevalence of alteration in the tactile sensorial perception among diabetics. Early identification of signs, symptoms, and etiological factors may support nurses in the planning of evidence-based interventions for the prevention of future ulcerations and amputations.(AU)

Unilateral spatial neglect in the acute phase of ischemic stroke can predict long-term disability and functional capacity

OBJECTIVE: The aim of this study was to assess the relationship between the degree of unilateral spatial neglect during the acute phase of stroke and long-term functional independence. METHODS: This was a prospective study of right ischemic stroke patients in which the independent variable was the degree of spatial neglect and the outcome that was measured was functional independence. The potential confounding factors included sex, age, stroke severity, topography of the lesion, risk factors, glycemia and the treatment received. Unilateral spatial neglect was measured using the line cancellation test, the star cancellation test and the line bisection test within 48 hours of the onset of symptoms. Functional independence was measured using the modified Rankin and Barthel scales at 90 days after discharge. The relationship between unilateral spatial neglect and functional independence was analyzed using multiple logistic regression that was corrected for confounding factors. RESULTS: We studied 60 patients with a median age of 68 (34-89) years, 52% of whom were male and 74% of whom were Caucasian. The risk for moderate to severe disability increased with increasing star cancellation test scores (OR=1.14 [1.03-1.26], p=0.01) corrected for the stroke severity, which was a confounding factor that had a statistically positive association with disability (OR=1.63 [1.13-2.65], p=0.01). The best chance of functional independence decreased with increasing star cancellation test scores (OR=0.86 [0.78-0.96], p=0.006) corrected for the stroke severity, which was a confounding factor that had a statistically negative association with independence (OR=0.66 [0.48-0.92], p=0.017). CONCLUSION: The severity of unilateral spatial neglect in acute stroke worsens the degree of long-term disability and functional independence.

Standardization of the face-hand test in a Brazilian multicultural population: prevalence of sensory extinction and implications for neurological diagnosis

OBJECTIVE: The face-hand test is a simple, practical, and rapid test to detect neurological syndromes. However, it has not previously been assessed in a Brazilian sample; therefore, the objective of the present study was to standardize the face-hand test for use in the multi-cultural population of Brazil and identify the sociodemographic factors affecting the results. METHODS: This was a cross sectional study of 150 individuals. The sociodemographic variables that were collected included age, gender, race, body mass index and years of education. Standardization of the face-hand test occurred in 2 rounds of 10 sensory stimuli, with the participant seated to support the trunk and their vision obstructed in a sound-controlled environment. The face-hand test was conducted by applying 2 rounds of 10 sensory stimuli that were applied to the face and hand simultaneously. The associations between the face-hand test and sociodemographic variables were analyzed using Mann-Whitney tests and Spearman correlations. Binomial models were adjusted for the number of face-hand test variations, and ROC curves evaluated sensitivity and specificity of sensory extinction. RESULTS: There was no significant relationship between the sociodemographic variables and the number of stimuli perceived for the face-hand test. There was a high relative frequency of detection, 8 out of 10 stimuli, in this population. Sensory extinction was 25.3%, which increased with increasing age (OR=1.4[1:01–1:07]; p=0.006) and decreased significantly with increasing education (OR=0.82[0.71-0.94]; p=0.005). CONCLUSION: In the Brazilian population, a normal face-hand test score ranges between 8–10 stimuli, and the results indicate that sensory extinction is associated with increased age and lower levels of education.

La medida de la percepción emocional con el modelo de rasch / Measuring emotion perception with the rasch model

Resumen Reconocer y denominar expresiones emocionales son habilidades en cuyo estudio existe un creciente interés por parte de la psicología y las neurociencias; trastornos tales como el autismo, la esquizofrenia y la depresión se caracterizan por dificultades en reconocer las emociones ajenas. El hallazgo de diferencias a favor de las mujeres en Percepción Emocional (PE) ha sido replicado transculturalmente por lo que sirve como evidencia de validez. En esta investigación, de diseño instrumental, se construyeron 28 ítems y se pusieron a prueba mediante el modelo de Rasch (MR) en una muestra de población general española (102 varones y 102 mujeres; rango de edad=18-65). El ajuste datos-modelo fue suficiente. Las medidas de las personas muestran que el test resultó fácil (rango = -.60 a 4.14 logits). Se hallaron las diferencias sexuales predichas, d= -.36 (d con corrección de la atenuación= -.50); que ningún ítem mostrase funcionamiento diferencial (DIF) asociado al sexo y que la variable construida tenga propiedades intervalares añade confianza al valor estimado del tamaño del efecto. La construcción de una escala de intervalo en la que se localizan conjuntamente ítems y personas ofrece información cuantitativa y permite detectar patrones inesperados de respuesta que pueden ser de utilidad para el diagnóstico neuropsicológico.

Abstract Recognizing and labeling emotion expressions are abilities in whose study psychology and the neurosciences are increasingly interested; disorders such as autism, schizophrenia and depression are characterized by difficulties in recognizing others' emotions. The finding of sex differences favoring women in Emotion Perception (EP) has been replicated cross-culturally, and so it can be used as validity evidence. In this instrumental design study, some 28 items were constructed and tested by means of the Rasch model (RM) in a Spanish community sample (102males and 102 females; age range=18-65). Data-model fit was good enough. Person measures show that the test was easy (range = -.60 to 4.14 logits). Even so, the predicted sex differences favoring women were found, d= -.36 (disattenuated d= -.50). That no item showed sex-related Differential Item Functioning (DIF) and that the constructed variable has interval scale properties add confidence to the effect size estimated value. The construction of an interval scale on which EP items and persons are conjointly represented offers quantitative information and allows the discovery of unexpected response patterns.

Produção do conhecimento: bases genéticas, bioquímicas e imunológicas da síndrome de Meares-Irlen / Production of knowledge: genetic basis, biochemical and immunological of Meares-Irlen Syndrome

RESUMO A Síndrome de Meares-Irlen, deficiência de processamento visual identificada em indivíduos com dislexia, pode ser definida como um distúrbio visual perceptivo que acredita ser originado no córtex visual primário. Este estudo consiste em uma revisão integrativa da literatura que teve como objetivo analisar a produção científica em relação às bases bioquímicas, genéticas e imunológicas que podem estar compreendidas nesta condição. Os dados foram obtidos por meio de consulta online às bases de dados da Biblioteca Virtual de Saúde (BVS) que interconecta várias bases de dados referenciais, como SciELO (Scientific Electronic Library Online), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde), MEDLINE (Literatura Internacional em Ciências da Saúde) e Biblioteca Digital da UFMG. Foram incluídos no estudo um total de 16 artigos, compreendidos entre os anos de 1996 e 2014 que atenderam aos critérios de inclusão propostos. Muitos estudos têm sugerido associação da síndrome com alterações bioquímicas e genéticas. Alguns sustentam a hipótese de que alterações imunológicas e no metabolismo de ácidos graxos estejam envolvidas com problemas cognitivos e de aprendizado. Apesar do escasso volume de estudos sobre o tema, existem evidências crescentes de que há uma base bioquímica envolvida em uma variedade de transtornos visuais e de aprendizagem.

ABSTRACT Meares-Irlen syndrome, deficiency of the visual processing identified in individuals with dyslexia can be defined as a visual perceptive disorder that is believed to be originated in the primary visual cortex. This study deals with an integrative literature review aimed to analyze the scientific production in relation to biochemical, genetic and immunological basis that maybe understood in this condition. Data were obtained via online query the databases of the Virtual Health Library (VHL) that interconnects several reference databases such as SciELO (Scientific Electronic Library Online), (Latin American and Caribbean Literature Rev Sciences health), MEDLINE (International Literature on Health Sciences), and the Digital Library of UFMG. A total of 16 articles, falling between 1996 and 2014 who met the inclusion criteria were included in the proposed study. Many studies have suggested an association of the syndrome with biochemical and genetic alterations. Some support the hypothesis that immune changes and metabolism of fatty acids are involved in cognitive and learning problems. Despite the scarce volume of studies on the subject, there is increasing evidence that there is a biochemical basis involved in a variety of visual disorders and learning.

Estereopsia en niños pseudofáquicos / Stereopsis in pseudophakic children

La estereopsia es el grado máximo que nos brinda la binocularidad y se desarrolla en los niños entre los 3 y 6 meses. Objetivo: determinar la presencia de estereopsia en niños pseudofáquicos, así como los factores asociados a la presencia de estereopsia en estos pacientes. Métodos: se realizó un estudio descriptivo, longitudinal y retrospectivo donde se incluyeron 25 niños mayores de 8 años previamente operados de catarata pediátrica en el Instituto Cubano de Oftalmología Ramón Pando Ferrer, que acudieron a la consulta entre junio y noviembre del año 2015. Se determinaron las variables estereopsia, lateralidad, origen de la catarata, edad de diagnóstico, edad de la cirugía y agudeza visual mejor corregida. Resultados: la estereopsia fina (60" o menos) se detectó en el 28 por ciento de los pacientes, y en el 68 por ciento algún grado de esta. Fue más frecuente en los pacientes con pseudofaquia bilateral y con cataratas traumáticas o del desarrollo, pero sin mostrar diferencias significativas. Todos los pacientes con estereopsia presentaron una agudeza visual mejor corregida mayor de 0,5 en su ojo de peor visión, y estadísticamente este resultado fue significativo. Conclusiones: la cirugía de catarata pediátrica permite desarrollar estereopsia. La agudeza visual posoperatoria es un factor determinante de esta(AU)

Stereopsis is the highest degree of binocularity and occurs in children aged 3 to 6 months of life. Objective: to determine stereopsis in pseudophakic children as well as the factors involved in stereopsis in these patients. Method: a retrospective, longitudinal and descriptive study of 25 children older than 8 years, who had been previously operated on of pediatric cataract in the Ramon Pando Ferrer Cuban Institute of Opthalmology. They went to the hospital from June to November, 2015. The variables were stereopsis, laterality, origin of cataract, age at diagnosis, age at the time of surgery and best corrected visual acuity. Results: fine stereopsis (60" or less) was detected in 28 percent of the patients, and some degree of it in 68 percent of them. It was more frequent in patients with bilateral pseudophakia and with traumatic or developmental cataract, but differences were not significant. All the stereoscopic patients had best corrected visual acuity over 0.5 in its worst vision eye, being this result statistically significant. Conclusions: the pediatric cataract surgery allows developing stereopsis and the postoperative visual acuity is a determining factor(AU)

Frequência e fatores associados à síndrome da mama fantasma em mulheres submetidas à mastectomia por câncer de mama / Frequency and associated factors of phantom breast syndrome in women submitted to mastectomy for breast cancer

OBJETIVO: Avaliar a frequência e os fatores de risco para o desenvolvimento da síndrome da mama fantasma em pacientes submetidas à mastectomia para o tratamento do câncer de mama.MÉTODOS: Estudo de coorte com mulheres atendidas em um hospital especializado da região sudeste do Brasil no período de setembro de 2008 a junho de 2009. Foram consideradas como tendo síndrome da mama fantasma pacientes com relato da presença de dor na mama fantasma e/ou sensação na mama fantasma. O estudo foi aprovado pelo Comitê de Ética em Pesquisa do Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA) (015/08). Foi realizada análise descritiva por meio da frequência absoluta e relativa. Para avaliar a associação entre a SMF e os potenciais fatores de risco, foi realizada análise univariada, por meio de odds ratios(OR) com os respectivos intervalos com 95% de confiança (IC95%).RESULTADOS: Foram incluídas 88 pacientes. A frequência da SMF observada aos 45 dias (primeiro seguimento) foi de 44,3 e 18,2% aos 2 anos (último seguimento). A maioria das mulheres apresentou relato de sensação na mama fantasma em todos os seguimentos (37,1; 30,1 e 22%). No seguimento de 6 meses, mulheres com idade inferior a 60 anos apresentaram um risco 3,9 vezes maior de apresentar síndrome da mama fantasma (OR=3,9; IC95% 1,4-10,5) e aquelas com maior escolaridade (8 anos ou mais de estudo) apresentaram maior risco de desenvolver SMF (OR=2,6; I 95% 1,01-6,8).CONCLUSÃO: A população estudada apresentou alta frequência de SMF, com diminuição ao longo do seguimento pós-operatório. Sua ocorrência no seguimento de seis meses foi maior entre as mulheres mais jovens e com maior escolaridade.

PURPOSE: To evaluate the frequency and risk factors for the development of phantom breast syndrome in patients submitted to mastectomy after breast cancer treatment.METHODS: A cohort study of women undergoing treatment at the Hospital of Cancer III, National Cancer Institute José Alencar Gomes da Silva (INCA) from September 2008 to June 2009. PBS was considered based on report of phantom breast sensation and/or phantom breast pain. The study was approved by the Research Ethics Committee of the INCA (015/08). Descriptive analysis using absolute and relative frequency was performed. To evaluate the association between PBS and potential risk factors, univariate analysis was performed by means of odds ratios (OR) with respective 95% confidence intervals (95%CI).RESULTS: A total of 88 patients were included. The frequency of PBS observed was 44.3 at 45 days (first follow-up) and 18.2% at 2 years (last follow-up). Most women reported phantom breast syndrome in all segments (37.1; 30.1 and 22%). During the six month follow-up, women under the age of 60 years had a 3.93 times higher risk of PBS (OR=3.9; 95%CI 1.4-10.5) and those with higher education (8 years or more of study) had a higher risk of developing PBS (OR=2.6; 95%CI 1.01-6.8).CONCLUSION: The study population had a high frequency of PBS, which decreased over postoperative follow-up. Its occurrence after six months was higher among younger and more educated women.

Low haemoglobin levels increase unilateral spatial neglect in acute phase of stroke / Níveis baixos de hemoglobina aumentam a negligência espacial unilateral na fase aguda do acidente vascular cerebral

Objective The objective of this study was to evaluate the relationship between unilateral spatial neglect (USN) and haemoglobin (Hb) level in acute phase of stroke. Method Cross-sectional study was performed after right hemisphere ischemic stroke. Independent variable: Hb level (mg/dL); Outcome: USN; Potential confounding factors: Age, National Institutes of Health Stroke Scale (NIHSS), and glycaemia (mg/dL); Characterization variables were obtained from electronic medical records, Hb, mean corpuscular volume (MCV) and glycaemia by laboratory exams, and USN by cancellation and bisection tasks. The relationship between Hb and USN was assessed by Spearman correlation and linear regression model. Results 40 individuals were evaluated; it was observed that the higher the Hb level, the better the USN test performance, with the two being negatively correlated. There was no significant correlation between VCM level and USN performance. Conclusion Low hemoglobin levels may indicate a worse performance in USN cancellation and bissection tests in acute phase of stroke. .

Objetivo O objetivo do estudo foi avaliar a relação entre a negligência espacial unilateral (NEU) e hemoglobina (Hb) na fase aguda do acidente vascular cerebral (AVC). Método Foi realizado estudo transversal em pacientes com AVC de hemisfério direito dentro das primeiras 48 horas do ictus. Variáveis independentes: nível de Hb (mg/dL); Desfecho: NEU; Fatores potenciais de confundimento: Idade, National Institutes of Health Stroke Scale (NIHSS) e glicemia (mg/dL); A caracterização das variáveis foram obtidas por meio de prontuários eletrônicos, Hb e glicemia por exames laboratoriais, e NEU por meio do Line Cancellation (LCT), Star Cancelation (SCT), e Line Bisection Tasks (LBT). Resultados 40 indivíduos foram avaliados e foi observado que quanto maior os níveis de Hb, melhor o desempenho nos testes de NEU, demonstrando correlação negativa entre eles. Conclusão Níveis baixos de hemoglobina podem indicar pior desempenho nos testes de NEU na fase aguda do AVC. .

Heminegligência / Hemineglect

A heminegligência, um fenômeno em que uma disfunção leva a uma desatenção da metade do campo visual e da percepção corporal, geralmente decorre de lesões do hemisfério parietal e está associado a um pior prognóstico quando acompanhada de anosognosia. O objetivo deste estudo é apresentar o caso de um paciente do sexo masculino, 73 anos, que desenvolveu heminegligência espacial associada à anosognosia e hemianopsia à esquerda decorrentes de um acidente vascular encefálico isquêmico (AU)

Hemineglect, a phenomenon in which a dysfunction leads to inattention of half the visual fi eld and body perception, usually results from damage to the parietal hemisphere and is associated with a worse prognosis when accompanied by anosognosia. The objective of this study is to present the case of a male patient, 73, who developed spatial hemineglect and anosognosia associated with left hemianopia resulting from an ischemic stroke (AU)

The broad autism phenotype in parents of individuals with autism: a systematic review of the literature / O fenótipo ampliado do autismo em pais de indivíduos autistas: uma revisão sistemática da literatura

The broad autism phenotype (BAP) is a milder manifestation of the defining symptoms of the syndrome in individuals without autism. This study conducted a systematic review of studies about behavioral characteristics of interpersonal relationships, communication and rigidity, as well as about three cognitive models, Theory of Mind, central coherence and executive function, in parents of individuals with autism. The indexed databases were LILACS, IBECS, Web of Science, and MEDLINE, and the studies retrieved were published between 1991 and March 2012. Parents of individuals with autism have more difficulties in interpersonal relationships and in pragmatic language use and have more rigidity traits. The inclusions of the cognitive theories in the group of BAP characteristics were inconclusive (AU)

O fenótipo ampliado do autismo (FAA) é a manifestação atenuada de características qualitativamente similares às que definem a síndrome, em indivíduos não portadores do transtorno. O objetivo deste artigo é realizar uma revisão sistemática de estudos que abordam as características comportamentais relacionadas a interação social, comunicação e rigidez, além dos modelos cognitivos Teoria da Mente (Theory of Mind, ToM), coerência central e funções executivas, em pais de indivíduos autistas. As bases de dados consultadas foram: LILACS, IBECS, Web of Science e MEDLINE; foram selecionados estudos publicados entre 1991 e março de 2012. Os resultados apontaram que os pais de indivíduos autistas possuem déficits na interação social, na linguagem pragmática e traços de rigidez. A inclusão dos modelos cognitivos do autismo no grupo de características que compõem o FAA permanece inconclusiva (AU)

Estereopsis en niños operados de estrabismo en el Instituto Cubano de Oftalmología / Stereopsis in children operated on from strabismus at the Cuban Institute of Ophthalmology

Objetivo: determinar la presencia de estereopsis en los niños operados de estrabismo en el Instituto Cubano de Oftalmología Ramón Pando Ferrer. Métodos: se realizó un estudio observacional, descriptivo y transversal de marzo a octubre de 2011. Se seleccionaron aleatoriamente 50 niños a quienes se le realizó un examen oftalmológico completo. Resultados: predominó el sexo femenino 60 por ciento, el rango de edad fue de 3 a 4 años 32 por ciento. El 84 por ciento de los pacientes presentaban una agudeza visual de 1,0; de ellos, solamente 10 tenían estereopsis. El rango donde se obtuvo mayor cantidad de niños con estereopsis posoperatoria fue el de menores de 2 años. La mayoría de los niños tenían como diagnóstico una esotropía congénita, solamente tuvieron estereopsis con este tipo de estrabismo 5 niños, Otro tipo de estrabismo que presentaban fue la exotropia intermitente. Conclusiones: en la cirugía de estrabismo lograr el alineamiento ocular, su estabilidad y tener la unidad de visión en ambos ojos, no trae resultados sensoriales muy alentadores, si el niño no se opera a edades tempranas. Una intervención quirúrgica temprana resulta importante para mejorar los resultados funcionales visuales, principalmente antes de los 2 años de edad

Objective: to determine the existence of stereopsis in children operated on from strabismus in Ramón Pando Ferrer Cuban Institute of Ophthalmology. Methods: observational, descriptive and cross-sectional study from March to October, 2011. Fifty children were randomly selected to undergo a complete ophthalmologic exam. Results: females 60 percent and the 3 to 4 years-old age group 32 percent prevailed. In the study group, 84 percent of the patients had visual acuity of 1.0, and just 10 had stereopsis. The patients younger than 2 years old represented the highest number with postsurgical stereopsis. Most of the children were diagnosed as congenital esotropia, but just 5 children had stereopsis added to this type of strabismus. Another type of strabismus found was the intermittent exotropia. Conclusions: in the strabismus surgery, reaching the ocular alignment and its stability as well as the vision co-ordination in both eyes, does not attain very encouraging sensory outcomes when a child is operated on at later age. An early surgical intervention is important to improve the functional visual results, mainly before 2 years of age

Aspectos clínicos y modelos teóricos en el Síndrome de Neglect / Clinicalaspects and theoretical models in Neglect Syndrome

En este trabajo se revisa y discute el síndrome de neglect considerando diferentes modelos teóricos explicativos; de dirección atencional, de asimetrías hemisféricas cerebrales, del sesgo atencional o el modelo de atención selectiva. Se consideran los aspectos cognitivos, emocionales y neuroconductuales. El Síndrome de Neglect generalmente es consecuencia de un accidente cerebrovascular, afecta al hemisferio cerebral derecho y señala directamente al lóbulo parietal. Este es el resultado de una definición anatómica vasta más que una unidad fisiológica o funcional. El síndrome se manifiesta por déficits en la atención perceptiva y en la respuesta a estímulos presentados en el hemicampo contralesional. Es un síndrome heterogéneo. Pese a la preponderancia de las teorías de déficits atencionales, las explicaciones de déficits perceptivos y de representación del espacio están presentes. Son variaciones del síndrome la heminatención, la extinción, la hemicinesia y el neglect hemiespacial. Se resalta la importancia de incluir los aspectos emocionales y neuroconductuales junto con los cognitivos y la rehabilitación motora en el proceso de rehabilitación neuropsicológica del síndrome. Son característicos los síntomas de anosognosia, extinción, desinhibición de conducta, conducta de utilización o la falta de afecto. En cuanto a la recuperación y a cómo ocurre esta, se discuten varias explicaciones alternativas y se apunta el papel de la motivación como factor importante en el éxito de los tratamientos.

This paper reviews the syndrome Neglect considering different theoretical models: attentional direction; of cerebral hemispheric asymmetry, attentional bias, selective attention model. The cognitive, emotional and neurobehavioral characteristics are high lighted. Neglect syndrome usually results from a stroke that affects the right cerebral hemisphere and points directly to the parietal lobe. This is the result of an extensive anatomical definition more than that one functional unit or physiological. The syndrome is manifested by deficits in attention and perceptual responses to stimuli presented in the contralesional hemispace. Neglect is a heterogeneous syndrome. Despite the preponderance of theories of the attentional deficit, explanations of perceptual deficits and representation of space are present. The syndrome manifestations are the heminatención, the extinction, the hemispatial hemicinesia and the neglect. They are very important the emotional aspects as the cognitive, neurobehavioral and motor rehabilitation, in the neuropsychological rehabilitation process of syndrome. Symptoms of anosognosia, extinction, behavioral disinhibition, and the utilization behavior or lack of affection are the most prominent in the syndrome. In terms of recovery, how to happen this? We discuss several alternative explanations and the role of motivation as an important factor in the success of treatments.

Diretrizes para avaliação e tratamento fisioterapêutico da Síndrome de Pusher: estudo de caso / Guidelines for assessment and physical therapy treatment in Pusher´s Syndrome: case report

A Síndrome de Pusher (SP) é uma alteração perceptual presente em 10% dos casos de hemiparesia causada por Acidente Vascular Encefálico (AVE). Caracteriza-se por queda para o lado parético, comportamento de empurrar-se para o lado acometido com o hemicorpo não parético e resistência à correção externa. Este estudo visou descrever a avaliação, o tratamento e a evolução de uma paciente com hemiparesia à esquerda e SP, devido a um AVE no hemisfério cerebral direito. Seis meses após a lesão, a paciente realizou testes perceptuais (do desenho da figura humana, comportamental de inatenção, escala de avaliação do sintoma de empurrar, miniexame do estado mental) e de desempenho funcional (escala de avaliação postural para pacientes com AVE, teste de função manual de Jebsen-Taylor, medida de independência funcional e índice de Barthel) e iniciou fisioterapia duas vezes por semana. Cada sessão teve 3 partes de 20 minutos: estimulação sensorial, treino motor e integração sensório-motora. Após o tratamento a paciente foi reavaliada e apresentou melhora em todas as escalas. A de avaliação do sintoma de empurrar e o teste de função manual de Jebsen-Taylor foram os que registraram maiores percentuais de melhora, 79% e 46%, respectivamente. O protocolo utilizado, mesmo tendo sido iniciado seis meses após a lesão, proporcionou melhora perceptual e funcional, o que sugere a importância da fisioterapia na recuperação da SP.

The Pusher´s Syndrome (PS) is a perceptual disorder that occurs in 10% of the cases of hemiparesis caused by stroke. It is characterized by falling to the paretic side, pushing to the paretic side with the non-paretic side and resisting to external correction. The present study aimed to describe the assessment, treatment and clinical evolution of a patient with left paresis and PS, caused by a stroke on the right hemisphere. Six months after the lesion, the patient was submitted to perceptual (human figure drawing test, behavioral inattention test, scale for contraversive pushing, minimental state examination) and functional performance tests (postural assessment stroke scale, Jebsen-Taylor hand function test, functional independence measure and Barthel index) and started physical therapy twice a week. Each session consisted of 3 parts of 20 minutes: sensory stimulation, motor training and sensory-motor integration. After six months, the patient showed improvement in all scales. The scale for contraversive pushing and the Jebsen-Taylor hand function test showed the highest percentages of improvement, 79% and 46%, respectively. Besides having been started six months after the lesion, the protocol of the present study contributed to the improvement of perception and functional performance. These findings suggest the importance of the physical therapy treatment in the recovery of individuals with PS.
