Pseudotumoral form of cerebral Schistosomiasis Mansoni

The authors report a case of 36-year-old woman presented with epileptic seizures and headaches. Magnetic resonance imaging (MRI) revealed an enhancing lesion with surrounding edema and mild mass effect in the left frontal lobe. Stereotactic brain biopsy demonstrated intraparenchymal granulomas surrounding S. mansoni eggs. Praziquantel was started (60mg/kg of body weight, in a single dose), followed by Prednisone (80mg/day) for seven days to treat the cerebral edema. The patient's symptoms resolved following medical treatment and the follow-up MRI yielded normal findings.

Effects of Jugular Vein Occlusion on Cardiovascular Parameters in Horses During Exercise on a Treadmill

The purpose of the present investigation was to examine the effects of unilateral and bilateral jugular vein occlusion by temporary surgical ligature on the heart rate and arterial and venous blood pressure in sedentary horses during progressive treadmill exercise. Six horses performed three exercise tests (ET). ET1, considered the control, was performed in horses without jugular occlusions. ET2 and ET3 were performed with unilateral and bilateral occlusion by temporary surgical ligature of the jugular veins, respectively. Heart rate, arterial pressure, and pressure of the occluded jugular vein were evaluated. Clinically, the horses presented apathy, head edema, congested mucous membranes, increased capillary refill time, and dysphagia. These signs were observed with the unilateral jugular vein occlusion and became more evident with the bilateral occlusion. Comparing ETs, no differences were observed in heart rate. However, jugular occlusions promoted a decrease in the mean arterial pressure and a severe increase in jugular pressure. Head edema caused by the jugular vein occlusion in the horses could interfere with the autonomic cardiovascular regulation of arterial blood pressure during exercise, likely leading to an impairment of tissue perfusion. Jugular occlusion, even unilateral, also causes severe head venous congestion, leading to venous hypertension that was aggravated by exercise, which could risk development of cerebral edema and neurological damage. The present results obtained from sedentary horses are preliminary data that lead us to suggest that sport horses presenting jugular occlusive thrombophlebitis, even unilateral, may be prevented from performing athletic activities. © 2013 Elsevier Inc.

Edema cerebral crônico na neurocisticercose

Neste estudo retrospectivo, relatam-se as características clínicas do edema cerebral crônico (ECCr) em 34 pacientes com neurocisticercose (NCC), que apresentavam edema cerebral difuso, à tomografia computadorizada (TC), como característica comum. Todos foram tratados com dextroclorofeniramina e, 32 deles, com albendazol. O ECCr predominou no sexo feminino (73,5%) na faixa etária dos 11 - 40 anos (92,3%). A cefaléia ocorreu em 94,1% dos pacientes, náuseas/vômitos em 47,1%, crises epilépticas em 41,1% e distúrbios psíquicos em 38,2%. A hiperreflexia ocorreu em 82,3% e o papiledema em 58,8% e o exame neurológico normal em 11,8%. Na TC, o edema esteve associado a calcificações em 61,8% dos casos. As pressões liquóricas foram mais elevadas (p< 0,05) antes do tratamento. Atualmente, estão assintomáticos, ou com melhora clínica, 79,4% dos pacientes (57,1% deles sem medicação). Discute-se a possibilidade do ECCr, na NCC, ser uma manifestação antigênica, sem a presença concomitante de cistos parasitários, e poder representar mais uma condição clínica associada à hipertensão intracraniana benigna.

Intravitreal injection versus sub-Tenon's infusion of triamcinolone acetonide for refractory diabetic macular edema: A randomized clinical trial

PURPOSE. To compare the effectiveness of posterior sub-Tenon's infusion (STi) and intravitreal injection (IVI) of triamcinolone acetonide (TA) for treatment of refractory diffuse diabetic macular edema.METHODS. Thirty-six phakic diabetic patients with refractory diffuse diabetic macular edema were prospectively enrolled. Patients randomly received either 40 mg STi or 4 mg IVI of TA. Comprehensive ophthalmic evaluation was performed at baseline and 1, 2, 4, 8 +/- 1, 12 +/- 2 and 24 +/- 2 weeks after treatment. Macular morphologic changes detected by optical coherence tomography and visual acuity, intraocular pressure, and lens status were evaluated.RESULTS. Twenty-eight patients (28 eyes) completed the 24-week study. Central macular thickness was significantly reduced in the IVI group when compared with the STi group at 2, 4, 8, 12, and 24 weeks after treatment (P < 0.01). Mean visual acuities (in logarithm of the minimum angle of resolution [logMAR]) at week-4, -8, and -12 follow-up examinations were significantly higher in the IVI group (0.74, 0.75, and 0.82, respectively) when compared with the STi group (0.88, 0.88, and 0.90, respectively; P < 0.01). A significant change from baseline in mean intraocular pressure (mm Hg) was seen at weeks 4 (+/- 3.21) and 8 (+/- 3.35) in STi the group (P < 0.01), and at week 8 (+/- 2.78) in the IVI group (P < 0.05). No patient had cataract progression during the study.CONCLUSIONS. Although the number of patients and length of follow-up in this preliminary study were limited, the changes in central macular thickness and visual acuity observed after treatment suggest that IVI TA may be more effective than STi for the management of refractory diffuse diabetic macular edema. Further studies are needed to confirm these preliminary findings.

Inclusão do aluno com dismotria cerebral ontogenética: analise das práticas pedagógicas

Há poucas investigações quanto às práticas educativas escolas, ou seja, os procedimentos que são utilizados pelo educador para promover a aprendizagem de seus alunos. Deste modo, o objetivo deste trabalho é analisar as práticas educativas escolares, e verificar em que medida essas práticas contribuem para a inclusão do aluno com Necessidades Educacionais Especiais. O presente estudo optou pelo estudo exploratório contemplando observações em sala de aula, bem como, no ambiente escolar. As observações ocorriam semanalmente sem datas fixas, e em horários diferentes, a fim de que fosse possível observação num ambiente típico. Utilizou-se também a entrevista e a análise de documentos do aluno (redação, provas, atividades acadêmicas) e da escola. Participaram do presente estudo um aluno que apresenta dismotria cerebral ontogenética, sua mãe, bem como, as professoras que lecionaram à ele durante os anos de 2000 e 2001. Os dados coletados auxiliaram para definir a categoria que foi foco da presente pesquisa: desempenho e rendimento escolar e percepção do aluno sobre seu processo de aprendizagem. Como conclusão o presente estudo constatou que o processo de inclusão do aluno, no tocante à inclusão física social, responde até certo grau às suas necessidades. No entanto, do ponto de vista de aprendizagem, não houve inclusão educacional, as práticas educativas observadas não contemplavam a especificidade curricular e de aprendizagem a fim de atender às necessidades do aluno.

Textura do recurso pedagógico e implicações em atividade de encaixe realizada por indivíduos com paralisia cerebral

O estudo teve o propósito de verificar a influência da textura do recurso pedagógico no tempo despendido e no índice de retidão para execução de uma atividade de encaixe realizada por indivíduos com paralisia cerebral. Participaram do estudo 6 alunos com sequelas de paralisia cerebral do tipo espástica, com idade entre 7 anos e 8 meses e 28 anos e 1 mês. O participante deveria segurar o objeto e levá-lo a um ponto demarcado previamente para o encaixe e, após, retorná-lo à posição inicial. O objeto foi apresentado nas texturas lisa, intermediária e áspera, de forma aleatória. Para a coleta de dados, foi utilizada filmagem para posterior leitura pelo programa Kavideo, que possibilitou cálculos para observar o tempo despendido na tarefa e o índice de retidão. Foi realizado o estudo da normalidade das distribuições, verificada por meio do teste de normalidade de Kolmogorov-Smirnov (Teste KS) e a comparação entre as texturas lisa, intermediária e áspera, no movimento de encaixe, por meio da análise de variância de medidas repetidas. Adotou-se para todos os testes nível de significância de 5% de probabilidade para a rejeição da hipótese de normalidade. O resultado do teste de análise de variância de medidas repetidas mostrou que não houve significância para as variáveis estudadas com o recurso apresentado nas três texturas. Porém, os dados da estatística descritiva mostraram que o encaixe do recurso com a textura lisa despendeu um menor tempo para execução da tarefa e, também, determinou um melhor desempenho com relação à trajetória do movimento.

Identification of the Communicative Abilities of Brazilian Children With Cerebral Palsy in the Family Context

This article highlights the importance of the information obtained from the family in the implementation of the augmentative and alternative communication (AAC) system. The objective was to investigate the communicative abilities of children with severe communication deficit through their parents' reports within the family routine. Eleven parents of children affiliated with a rehabilitation program in a public university in Brazil participated in this research. Per their parents' reports, the children demonstrated a variety of communication skills related to comprehension, expressive skills, and vocabulary. Parents further reported their children's daily communication routines including social partners, communication environment, and the materials the children enjoyed the most. These results emphasize the importance of family involvement in planning AAC so that it is functional within the family context.

Quantitative comparison of mobility and gross motor function in Brazilian children with cerebral palsy

Background: Cerebral palsy (CP) presents changes in posture and movement as a core characteristic, which requires therapeutic monitoring during the habilitation or rehabilitation of children. Besides clinical treatment, it is fundamental that professionals use systems of evaluation to quantify the difficulties presented to the individual and assist in the organization of a therapeutic program. The aim of this study was to quantitatively verify the performance of children with spastic di-paresia type CP.Methods: The Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Classification System (GMFM) tests were used and classification made through the GMFCS in the assessment of 7 patients with CP, 4 females and 3 males, average age of 9 years old.Results: According to GMFCS scales, 17% (n=1) were level II and 83% (n=6) were level III. The PEDI test and 88 GMFM items were used in the area of mobility. We observed that there was high correlation between mobility and gross motor function with Pearson's correlation coefficient =0.929) showing the likely impact of these areas in the functional skills and the quality of life of these patients.Conclusion: We suggest the impact of the limitation of the areas in functional skills and quality of life of these patients.

Characterization of the motor performance in infants with a diagnosis of Cerebral Palsy in process of rehabilitation: the importance of the proactivity of caregivers

Introduction: The progress in technology, associated to the high survival rate in premature newborn infants in neonatal intensive care units, causes an increase in morbidity. Individuals with CP present complex motor alterations, with primary deficits of abnormal muscle tone affecting posture and voluntary movement, alteration of balance and coordination, decrease of force, and loss of selective motor control with secondary problems of contractures and bone deformities.Objective: The aim of this work is to describe the spontaneous movement and strategies that lead infants with cerebral palsy to move.Methods: Seven infants used to receive assistance at the Essential Stimulation Center of CIAM (Israeli Center for Multidisciplinary Support - Philanthropic Institution), with ages ranging between six and 18 months with diagnosis of Cerebral Palsy (CP) were assessed.Results: The results show the difficulty presented by the infants with respect to the spontaneous motor functions and the necessity of help from the caregiver in order to perform the functional activity (mobility). Prematurity prevails as the major risk factor among the complications.Conclusion: The child development can be understood as a product of the dynamic interactions involving the infant, the family, and the context. Thus, the social interactions and family environment in which the infant live may encourage or limit both the acquisition of skills and the functional independence.

Cerebral ischemia as initial neurological manifestation of atrial myxoma: case report

Infartos cerebrais de etiologia cardíaca são observados em cerca de 20% dos pacientes com acidente vascular cerebral isquêmico. Infarto cerebral ocorre como manifestação clínica inicial em um terço dos casos de mixoma atrial. Embora quase metade dos pacientes com mixoma atrial apresente alteração ao exame neurológico, infarto cerebral não hemorrágico é visto na tomografia computadorizada em praticamente todos os casos. Os autores apresentam o caso de uma paciente, cuja primeira manifestação clínica do mixoma atrial foi um acidente vascular cerebral isquêmico e chamam a atenção para a possibilidade de infarto cerebral silencioso em pacientes portadores de mixoma atrial.
