Resumen El objetivo de este estudio fue realizar el análisis psicométrico de la escala Teacher Observation of Classroom Adaptation-Revised (TOCA-R) para su uso en escuelas brasileñas, y evaluar su validez y confiabilidad. Esta escala ha sido utilizada para evaluar el "Programa Elos", que es la versión brasileña culturalmente adaptada del programa norteamericano "Good Behavior Game". El instrumento fue adaptado por los investigadores en 2014 y está compuesto por 33 ítems con una escala de respuesta ordinal de tres puntos. En este estudio, se utilizó un diseño longitudinal cuasiexperimental de grupo único con los niños de 6 a 10 años, evaluados por sus maestros antes (n = 1448) y después (n = 673) de la implementación del Programa Elos en 2014. Se incluyeron cuatro ciudades brasileñas, 19 escuelas, 68 cursos y sus respectivos maestros, y los procedimientos analíticos fueron el análisis factorial exploratorio, el análisis factorial confirmatorio, el análisis de invariancia longitudinal y el análisis de confiabilidad por coeficientes de precisión. Los resultados del análisis factorial exploratorio mostraron un ajuste aceptable de cinco factores con 25 ítems, con una varianza total explicada del 60 % y un error residual medio de 0.02; el análisis factorial confirmatorio mostró un ajuste satisfactorio del modelo (χ2 = 961, df = 265, RMSEA = .078, IC 95 % = .07-.08, y CFI = 0.9); y se identificó la invariancia configuracional, métrica y escalar de la estructura latente, la cual, junto con la amplitud de variación de los coeficientes de precisión entre las dimensiones del instrumento (α = .78, .92; ω = .76, .92), da cuenta de evidencias de validez y confiabilidad que permiten utilizar la escala en la evaluación del Programa Elos en las escuelas brasileñas.

Abstract The aim of this study was to describe the process of psychometric analysis of the Teacher Observation of Classroom Adaptation- Revised Scale (TOCA-R) for its use in Brazilian schools and to evaluate its validity and reliability. To evaluate the "Elos Program", which is the Brazilian culturally adapted version of the North American Program "Good Behavior Game", the TOCA-R was used. The researchers adapted the instrument in 2014, consisting of 33 items in a three-point ordinal response scale. A longitudinal quasi-experimental design with a single group was used. Participants were children aged 6 to 10 years evaluated by their teachers, before (n = 1448) and after (n = 673) the implementation of the Elos Program in 2014. The study involved initially four schools, 68 classes and their respective teachers. The analytical procedures were exploratory factorial analysis, confirmatory factorial analysis, longitudinal invariance analysis and reliability analysis by precision coefficients. The results of the exploratory factorial analysis showed an acceptable adjustment of five factors with 25 items, with a total explained variance of 60% and mean residual error of 0.02. The confirmatory factorial analysis expressed a satisfactory fit of the model (χ2 = 961, df = 265, RMSEA = .078, 95% IC [.07, .08], and CFI = 0.9). A configurational, metric and scalar invariance of latent structure was identified, which, together with the amplitude of variation of the precision coefficients between the instrument dimensions (α = .78, .92; ω = .76, .92), demonstrate evidence of validity and reliability for using the TOCA-R in evaluating the Elos Program in Brazilian schools.

A função otolítica pode ser avaliada pela Vertical Visual Subjetiva (VVS) que determina a capacidade de um indivíduo julgar se objetos estão na posição vertical na ausência de outras referências visuais. O objetivo deste estudo foi avaliar a VVS em indivíduos brasileiros normais usando um aparelho portátil. As medidas da VVS foram realizadas em 160 indivíduos (16 a 85 anos). O valor médio da VVS foi obtido após dez ajustes. A VVS teve valores médios entre -2,0º e +2,4º (média=0,18º, e DP=0,77º). Não houve diferença entre as médias da VVS em relação à idade (teste de Kruskal-Wallis; p=0,40), mas as faixas etárias maiores tiveram variância maior (teste de Levene; p=0,016). Os valores da VVS encontrados neste estudo foram semelhantes aos registrados na literatura. Não houve diferença nas médias das inclinações da VVS de acordo com a idade, mas foi encontrada maior variância entre indivíduos mais idosos.

Otolith function can be evaluated by subjective visual vertical (SVV) that determine the capacity of a subject to judge if the objects are on vertical position with absence of any visual reference. The aim of this study was to evaluate the SVV in a sample of normal Brazilian subjects using a portable device. Measurements of SVV were performed in 160 normal subjects (aged from 16 to 85). SVV mean value was obtained after ten adjustments. SVV mean values ranged from -2.0º to +2.4º (mean=0.18º, and SD=0.77). Considering all age groups, there was no difference of SVV mean values (Kruskal-Wallis test; p=0.40), but older groups had a greater variance (Levene test; p=0.016). SVV values observed in this study are comparable to those described in previous studies. Although there was no difference in mean SVV-inclination according to age, there was a greater variance in older subjects.

O "Status Dystonicus" (SD) é uma situação clínica caracterizada por contratura muscular generalizada em pacientes com distonias. Relatamos cinco casos de SD, que ocorreram em dois pacientes com distonia associada à paralisia cerebral, um paciente com distonia segmentar primária, um com síndrome de Hallervorden-Spatz e um com doença de Wilson (DW). Três pacientes foram submetidos a tratamento em terapia intensiva com uso de propofol e midazolam e dois pacientes foram submetidos ao tratamento neurocirúrgico (um paciente com palidotomia bilateral e outro com estimulador cerebral profundo palidal bilateral). Em três casos foram identificados fatores desencadeantes: infecção, estresse acentuado e o uso de zinco no tratamento da DW. Em dois pacientes ocorreu melhora importante do quadro distônico, e outros três retornaram à situação clínica pré-SD.

Status Dystonicus (SD) is characterized by generalized muscle contractions in dystonic patients. We report 5 cases of SD, two of which in patients with dystonic cerebral palsy, one in a patient with primary segmental dystonia, one in a patient with Hallervorden-Spatz syndrome and one in a patient with Wilson's disease (WD). Three patients were admitted to an intensive care unit and treated with propofol and midazolam, and two were submitted to neurosurgical procedures (bilateral pallidotomy and bilateral pallidal deep brain stimulation). Triggering factors were identified in three patients as follows: infection, stress-induced and zinc therapy for WD. On follow-up, two patients presented with significant improvement of dystonia, whereas the other three cases the clinical picture ultimately returned to baseline pre-SD condition.

In Neurolinguistics, the use of diagnostic tests developed in other countries can create difficulties in the interpretation of results due to cultural, demographic and linguistic differences. In a country such as Brazil, with great social contrasts, schooling exerts a powerful influence on the abilities of normal individuals. The objective of the present study was to identify the influence of schooling on the performance of normal Brazilian individuals in the Boston Diagnostic Aphasia Examination (BDAE), in order to obtain reference values for the Brazilian population. We studied 107 normal subjects ranging in age from 15 to 84 years (mean ± SD = 47.2 ± 17.6 years), with educational level ranging from 1 to 24 years (9.9 ± 4.8 years). Subjects were compared for scores obtained in the 28 subtests of the BDAE after being divided into groups according to age (15 to 30, N = 24, 31 to 50, N = 33 and 51 years or more, N = 50) and education (1 to 4, N = 26, 5 to 8, N = 17 and 9 years or more, N = 61). Subjects with 4 years or less of education performed poorer in Word Discrimination, Visual Confrontation Naming, Reading of Sentences and Paragraphs, and Primer-Level Dictation (P < 0.05). When breakdown by schooling was 8 years or less, subjects performed poorer in all subtests (P < 0.05), except Responsive Naming, Word Recognition and Word-Picture Matching. The elderly performed poorer (P < 0.05) in Complex Ideational Material, Visual Confrontation Naming, Comprehension of Oral Spelling, Written Confrontation Naming, and Sentences to Dictation. We present the reference values for the cut-off scores according to educational level.

O vasoespasmo cerebral é responsável por aumento de morbidade e mortalidade em pacientes acometidos por hemorragia subaracnóide (HSA). Sua detecção de forma precoce e não-invasiva pelo método de Doppler transcraniano (DTC) pode contribuir para um melhor prognóstico destes doentes. OBJETIVO: Discutir o uso do método de DTC para diagnóstico do vasoespasmo cerebral secundário à HSA espontânea. MÉTODOS: Foram analisados os registros de velocidade de fluxo em artérias intracranianas por DTC em 31 pacientes com diagnóstico tomográfico de HSA, realizados seqüencialmente em conjunto com exame neurológico. Todos os pacientes (à exceção de um) eram portadores de aneurismas intracranianos. RESULTADOS: Vasoespasmo clínico foi constatado em 11 pacientes (36,6% do total), com correspondente vasoespasmo ultra-sonográfico presente em nove casos (82%). Em três casos (33,3%) as alterações de velocidade de fluxo precederam os sinais clínicos. Entre os 20 pacientes assintomáticos, 15 (75%) apresentaram medidas de velocidade normais, havendo evidência de vasoespasmo sonográfico sem repercussão clínica em cinco (25%). O índice de falso negativo na correlação entre exame clínico e DTC (sinais clínicos de vasoespasmo presentes, com velocidades de fluxo normais) foi de 18%. No entanto, houve correspondência entre os achados clínicos e ultra-sonográficos em 26 dos 31 pacientes (83,8%). Os valores de velocidades médias nas várias artérias e sua interpretação para cada subgrupo são discutidos com maiores detalhes. CONCLUSÃO: O método de DTC é um auxiliar valioso na detecção pré-sintomática do vasoespasmo secundário à HSA, permitindo uma intervenção terapêutica mais precoce. Os dados obtidos neste trabalho coadunam-se com os diversos estudos publicados na literatura.

Cerebral vasospasm accounts for an increased morbidity and mortality in patients with spontaneous subarachnoid hemorhage (SAH). Its early and non invasive detection by transcranial Doppler (TCD) may contribute to a better prognosis in such cases. PURPOSE: To discuss the use of transcranial Doppler (TCD) in the detection of cerebral vasospasm secondary cerebral to spontaneous subarachnoid hemorrhage (SAH). METHODS: We analyzed the flow velocities registered by TCD in intracranial arteries in 31 patients with SAH, performed sequentially, associated with neurological examinations. All patients (except one) had intracranial aneurysms. RESULTS: Clinical vasospasm was found in 11 patients (36,6% from the total), with correspondent sonographic vasospasm present in 9 cases (82%). In 3 cases (33.3%) the flow velocity alterations preceded the clinical symptoms. Between the 20 asymptomatic patients, 15 (75%) had normal flow velocity, with evidence of sonographic vasospasm without clinical repercussion in 5 (25%). The index of false negatives in the correlation between clinical examination and TCD (symptomatic vasospasm with normal flow velocity records) was 18%. However, there was correspondence between clinical and ultrasonographic findings in 26 of the 31 patients (83.8%). The average flow velocity values in the various arteries and its interpretation for each subgroup are discussed with further details. CONCLUSION: TCD is a valuable auxiliary method in the detection of cerebral vasospasm (even pre-symptomatic) secondary to SAH, allowing a more precocious therapeutic intervention. Our results are similar to those described in the literature.

O comprometimento do sistema nervoso periférico é frequente nas vasculites sistêmicas e contribui decisivamente para o diagnóstico. Oito pacientes foram estudados: sete do sexo feminino e um do sexo masculino; cinco brancos, dois negros, um amarelo; média de idade de 55,9 anos; quatro com poliarterite nodosa, um com lúpus eritematoso sistêmico, um com artrite reumatóide, um com vasculite isolada do sistema nervoso periférico e um com vasculite livedóide. Todos foram submetidos a terapêutica intravenosa com pulsos mensais de metilprednisolona (1 g/dia/3dias) e ciclofosfamida (1 g/dia). Cinco pacientes melhoraram, dois permaneceram inalterados e um faleceu. A melhora neurológica objetiva ocorreu após o terceiro ou quarto pulso e nos pacientes com menor duração da doença.

The peripheral nervous system is frequently involved in systemic vasculitis and it may be helpful in the disease diagnosis. We report on eight patients: seven women and one man; five white, two black and one yellow; age mean 55.9 years; four had polyarteritis nodosa, one had systemic lupus erythematosus, one had isolated peripheral nerve vasculitis and one had livedoid vasculitis. All of them received endovenous therapy with "pulse" of methylprednisolone (1 g/day/3days) and cyclophosphamide (1 g/1day). Five patients improved, two remained unchanged and one died. The neurological improvement occurred after the third or fourth pulse and in the patients who have had a shorter time of disease.

The objective of our study was to describe by histologic methods the structural organization of the antennal gland of M. potiuna as well as the location through histochemical methods of the neutral and sulfated polissacharides that exist in these regions. This study showed that the gland is composed of the a non-secretive tubular portion and a secretive portion which is formed by a cubic simple epithelium, sub-epithelium layer and cellular chains

Os desempenhos em testes neuropsicológicos de trinta pacientes, com diagnóstico de demência leve ou moderada baseado nos critérios do DSM-III-R, com escore no Mini-exame do Estado Mental inferior a 24 pontos e escolaridade mínima de 4 anos, foram comparados aos de trinta voluntários normais equiparados quanto a idade, escolaridade e sexo. Foram calculadas as sensibilidades e especificidades dos testes na distinção entre doentes e controles normais Dentre os testes empregados, o que demonstrou maior acurácia nesta distinção, calculada através de curva ROC, foi o de informação-memória-concentração de Blessed, seguido em ordem decrescente de acurácia, pelos de construção (cópias de figuras simples), memória verbal tardia (após 5 minutos), reconhecimento de 10 figuras e fluencia verbal (animais). Seis testes de aplicação e interpretação simples (fluencia verbal, percepção visual, memória visual incidental, cálculo, desenho de um relógio e memória tardia após 5 minutos) permitiram definir função linear discriminante que revelou elevada capacidade de discriminação entre pacientes e controles, na amostra. Esta função deve ser submetida à comprovação em outra casuística. Em virtude da simplicidade e rapidez de aplicação, poderá ser associada ao MEM para identificar indivíduos com demência e indivíduos sadios em estudos epidemiológicos.

Thirty patients with dementia defined by DSM-III-R criteria (Alzheimer's disease (22), vascular dementia (3), Parkinson's disease, frontal lobe dementia, possible diffuse Lewy body dementia, normal pressure hydrocephalus and uncertain diagnosis), with scores below 24 points in the Mini-Mental Status Examination and more than 4 years of education were submitted to a neuropsychological evaluation. The scores in the neuropsychological tests were compared to those obtained by thirty normal volunteers paired for age, sex and education. Sensivity, specificity and accuracy of the tests in the distinction of demented and normal volunteers were determined. The accuracies were calculated using ROC curves. Blessed's information-memory-concentration test showed greatest accuracy, followed by copy of simple figures, delayed memory of 10 figures (after 5 minutes), recognition of 10 figures and verbal fluency test (animals). A linear discriminant function, composed by 6 tests: visual perception, incidental memory, delayed memory (after 5 minutes), drawing of a clock, verbal fluency (animals) and calculation tests, was able to discriminate all controls from patients and only one patient was wrongly classified as normal control. These tests were chosen because they can be applied in less than 10 minutes and are very easy to interpret. This discriminant function must be applied in another group of patients and controls in order to demonstrate its value. When associated to the MMSE it may be useful to discriminate patients with dementia from normal people in epidemiological studies.

A coreatetose paroxistica (CP) é entidade rara. Até mesmo profissionais que estudam desordens do movimento não costumam vê-la com freqüência. A ocorrência paroxística de movimentos distônicos, coréicos e atetósicos é a apresentação típica da síndrome. O início costuma ser abrupto e os ataques podem durar de alguns segundos até horas. Casos esporádicos e, mais frequentemente, casos familiares têm sido relatados. A abordagem terapêutica com anticonvulsivantes, como a carbamazepina, nem sempre tem sucesso. Com esta droga, porém, geralmente há boa resposta na variante cinesiogênica da CP. É relatado o caso de um paciente jovem do sexo masculino com essa variante da CP. O início da doença se deu na puberdade. O exame neurológico era normal entre os ataques. A investigação laboratorial, EEG, TC de crânio e RNM de segmento cefálico foram normais. Carbamazepina em doses baixas (100 mg/dia) foi eficaz no manejo dos ataques.

Paroxysmal choreoathetosis (PC) is a rare entity, and professionals who study movement disordes do not find it easily. Paroxysmal occurence of dystonic, choreic, athetosic movements is the typical feature of this syndrome. The onset is always subtle and the attacks can last from few seconds to hours. Sporadic cases and more common familial cases have been reported. The therapeutic approach with anticonvulsivant drugs like carbamazepine is not always successful. However, there is a good response to this drug in the kinesigenic form of PC. The case of a 21 years old male patient is reported here. The onset occurred during puberty, at 14 years old. Neurologic examination was normal between attacks. Subtle and brief choreic, athetosic and dystonic limb and legs movements precipitated by sudden quick and unexpected passive movements, as by startle, were observed during the attacks. There was no familial history. Routine laboratorial investigation, EEG, CT scan and MRI did not show significant changes. Carbamazepine in low dosages (100 mg/day) brought a complete control of the attacks.

Foram avaliados prospectivamente 118 pacientes (79 homens e 39 mulheres, com média de idade de 50,7 anos) submetidos a cirurgia cardiovascular com circulação extracorpórea. O objetivo foi identificar as complicações neurológicas mais freqüentes e relacioná-las a fatores de risco. As cirurgias tiveram a seguinte distribuição: 71 pacientes foram submetidos a revascularização do miocárdio, 18 a troca valvar. 6 a retroca valvar, 11 a comissurotomias. 5 a correção de aneurisma de aorta torácica e 7 a outros tipos. Apresentaram alterações neurológicas no primeiro período pós operatório 14 (11,9%) pacientes: delirium em 7 casos, acidente vascular cerebral isquêmico em 6 e crise epiléptica em 3. Os pacientes com hipertensão arterial sistêmica e os mais idosos tiveram risco maior de complicação neurológica, com significância estatística (p<0,05). Observou-se baixo índice de morbidade e mortalidade em relação aos dados de literatura

118 patients (79 mean and 39 women, mean age of 50.7 years) who underwent cardiovascular surgery and extracorporeal oxygenation were prospectively evaluated for neurologic complication and its correlation with risk factors. 71 were submitted to coronary artery graft by-pass (RM), 18 to valve replacement (TV), 6 to prosthetic valve replacement (RV), 11 to commissurotomy (Co), 5 to thoracic aortic aneurysm correction (An Ao T) and 7 to other surgeries (OT). All of them received extracorporeal oxygenation. No deaths were registered; 14 (11.9%) patients had neurologic abnormalities: delirium in 7 cases, ischemic stroke in 6, epileptic seizure in 3. Patients with systemic arterial hypertension and older patients exhibited a statistically significant (p<0.05) higher risk of complication. Compared to data of the lite, rature, we had a lower index of morbidity and mortality.

Coréia pode ocorrer como manifestação neurológica do lupus eritematoso sistêmico, estando frequentemente associada à presença de anticorpos antifosfolípides. Evidência de coréia como sinal de atividade lúpica não foi descrita. Descrevemos o caso de uma paciente, com lupus eritematoso sistêmico e anticorpos antifosfolípides, que desenvolveu coréia, sendo esta manifestação considerada sinal de atividade dia doença.

Chorea may occur as a neurological manifestation of systemic lupus erythematosus and is often associated with detection of antiphospholipid antibodies. No evidence of chorea as a sign of lupus activity has been established. We describe a patient with systemic lupus erythematosus associated with antiphospholipid antibodies who developed chorea, which has been considered a sign of lupus activity.

São descritos três casos d© degeneração hepatolenticular (DHL.) em que o efeito nefrotóxico da D-penicilina (DP) levou à substituição dessa droga por zinco, com resultados satisfatórios. O tempo médio de tratamento com zinco nos casos descritos foi de 2 anos e 7 meses. Com base nos dados de literatura e na experiência com esses pacientes, os autores consideram que os sais de zinco podem ser uma alternativa para o tratamento da DHL quando a DP determina o aparecimento de efeitos colaterais graves que levam à sua retirada definitiva.

Three patients with symptoms and signs of hepatolenticular degeneration (HLD) who developed serious renal side effects of D-penicillamine (DP) had their therapeutic schedule changed to zinc. Patient 1, a 55 year-old man had been well until 12 years old, when skeletal changes (osteomalacia) due to tubular renal disturbance began. His diagnosis of HLD had first been established at age of 32 when he presented with «wing-beat» tremor. He was then begun on DP and his neurological symptons resolved within one year of initiating therapy but skeletal abnormalities remained unchanged as a sequel. During the next 22 years the patient was continued on DP therapy but with poor compliance. Then the reapperance of his neurological manifestations occurred several times. By the age of 53, after one year without therapy, his neurological status has worse. DP was reinstituted but some weeks later his renal laboratorial parameters became serevely affected. DP was discontinued and zinc sulfate (220mg three times daily) was introduced. On this therapeutic regimen his renal laboratorial parameters returned to previous level after one month. Within one year on this therapeutic regimen neurological manifestations were resolved. After 31 months on zinc treatment he remains neurologically asymptomatic and his renal function is satisfactory. Patient 2, a 41 years old woman had been her diagnosis of HLD at age of 20, when following the diagnosis of the disease in her old brother, she was found to have the laboratorial features of HLD and bilateral Kayser-Fleischer rings. DP treatment was recommended at that time but she quitted the follow-up. When she. was 23, an esophageal variceal bleeding occurred. At the age of 30 she started DP treatment. During 9 years the patient, under regular use of the drug remained assymptomatic. At the age of 39 she developed acute renal failure due to penicillamine-induced immune complex nephropathy. DP was then stopped and prednisone introduced. After 4 months, as renal function returned to normal, prednisone was discontinued and zinc sulphate (220mg three times daily) introduced. She remained asymptomatic for 38 months. By the age of 41 a relapse of renal manifestations occurred, and she died months later. Patient 3, a 20 year-old man developed hemolytic anemia as the single manifestation of HLD at 16. DP was introduced with excellent results. Neverthless, 4 months later, with the appearance of severe renal side--effects, this drug was replaced by zinc sulphate (220mg three times daily). After 11 months under this therapeutic schedule he was hematologically asymptomatic but an epigastric distress appeared. Zinc sulphate was discontinued and zinc acetate (170mg three times daily) was introduced. Since that time, after 30 months of treatment with zinc, he remains asymptomatic and Kayser-Fleisher rings disappeared. A review of zinc salts therapy of HLD is presented and discussed.

Foi avaliada a evolução neurológica, sob tratamento, de 76 casos de degeneração hepatolenticular. Dos 76 casos, 59 (77,6%) apresentariam melhora do quadro neurológico ou mantiveram-se assintomáticos, 8 (10,6%) permaneceram inalterados e 9 (11,8%) pioraram. Os principais fatores relacionados a resultados insatisfatórios foram: duração de tratamento insuficiente para permitir reversão de distúrbios neurológicos, uso irregular da medicação e predomínio de manifestações distônicas no quadro neurológico.

A series of 76 patients with hepatolenticular degeneration (HLD) followed up at the Hospital of the University of São Paulo Medical School between 1963 and 1988 have been studied focusing the evolution under treatment of neurological features. The assessment of neurological symptoms included 12. specific items, and it was made by a scoring system ranging from 0 to 3 (absent, mild, moderate and severe). Global score varied between 0 to 36. A functional disability scale (0, normal; 1, mild; 2, moderate; 3, severe) was also adopted. All patients received D-penicillamine but three of them developed serious renal toxic side-effects, and this drug was replaced by zinc (sulphate or acetate). Fifty-nine patients (77.6%) improved, 8 (10.6%) remained unchanged, and 9 (11.8%) got worse. The main features related to bad results were poor compliance, predominance of dystonic symptoms, and short time treatment (death due hepatic complications). Eight patients (10.5%) developed transient worsening of neurological symptoms during the first weeks of treatment. Three patients who have D-penicillamine replaced by zinc salts presented satisfactory evolution. From them, only one had neurological symptoms. Death due to infectious complications related to severe motor disability occurred in three patients, representing only 10.7% of fatal evolution.

Isotipos de imunoglobulinas (IgG e IgM) de proteína básica de mielina (PBM), cerebrosídeos (CER), gangliosídeos (GANG) e cardiolipina (CARD) foram investigados em amostras de liqüido cefalorraquidiano (LCR) de 33 pacientes com esclerose múltipla (EM), 18 com síndrome de Guillain-Barré (SGB), e 30 com lúpus eritematoso sistêmico (LES). Pacientes com EM revelaram concentrações positivas e significantes para IgG-PBM em 51,5% (p<0,05), IgM-PBM em 18,2%, IgG-CARD em 46,2%; CER e GANG foram detectados em cerca de 20% dos pacientes. A avaliação dos isotipos de imunoglobulinas no soro de pacientes com EM foi positiva em 20,6% para IgG-PBM e. 53,0% para IgM-PBM. No LCR dos pacientes com SGB a análise mostrou-se positiva em 56,3% para IgG-PBM (p<0,05), 53% para IgM-PBM, 38,5% para IgG-CER e 23% para IgM-CER, 50% para IgG-CARD e 31% para IgM-GANG. Os isotipos avaliados no soro de 14 pacientes com SGB foram positivos em 18,8% para IgG-PBM e 56,3% para IgM-PBM (p<0,05). No LCR, 50% dos pacientes com LES revelaram positividade para IgG-CARD e 241% para IgG-PBM. Os autores acreditam que a presença de anticorpos antifosfolipides seja conseqüente a epifenômeno imune, embora sua presença possa manter e perpetuar o evento imune intrínseco a essas doenças.

Immuneglobulins isotypes (IgG and IgM) for myelin basic protein (MBP), cerebrosides (CER), gangliosides (GANG) and cardiolipin (CARD) were detected in the cerebrospinal fluid (CSF) from 33 patients with multiple sclerosis (MS), 18 with Guillain-Barré syndrome (GBS) and 30 with systemic lupus erythematosus (SLE). In MS patients occurred positive and significant levels of IgG-MBP in 51,5% (p<0.05) and IgM-MBP in only 18.2%, IgG-CARD in 46.2%, as long as CER and GANG were detected in almost 20%. From serum samples of MS patients 20.6% presented IgG-MBP, while 53% showed positive levels foi IgM-MBP. The CSF analysis of patients with GBS showed that 56.3% revealed IgG-MBP (p<0.05), 53% for IgM-MBP. 3&.5% for IgG-CER and 23% for IgM-CER, while 50% of patients had IgG-CARD, as long -as 31% also had IgG-GANG. The serum evaluation from 14 patients showed that 18.8% had positive concentrations of IgG-MBP and 56.3% presented IgM-MBP (p<0.05) Except for 50% of patients with SLE who presented positive CSF levels of IgG-CARD. only 24.1% had positive levels of IgG-MBP. We believe that the presence of antiphosphohoid antibodies in CSF of the above mentioned diseases occurred as immune epiphenomena, but their appearance would permit the maintenance of and perpetuate the immune event.

Distúrbios do movimento, geralmente de tipo distónico, têm sido relatados em heterozigotos para doença de Wilson (DW). O presente relato assinala a presença em uma mesma família de heterozigoto para DW com quadro distónico e sua sobrinha com quadro clássico de DW. Discutem-se as peculiaridades dessa família, comparando-se aos dados da literatura, bem como os possíveis mecanismos etiopatrogênicos envolvidos.

Movement disorders, mostly dystonia, sometimes occur in heterozygotes for Wilson's disease (WD). A patient with metabolic abnormalities suggestive of heterozigose for WD and dystonia is reported. His niece showed the typical neurological and metabolic abnormalities of WD. This rare coincidence and the etiopathogenic mechanisms involved are discussed .
