ABSTRACT

Tourette syndrome (TS) and tic disorders represent events of familiar magnitude characterized by involuntary movements and/or vocalization. To determine the prevalence of TS/tic disorders we studied a sample of 762 subjects (388 M, 374 F), between 1992 and 1997, age 6 to 43 years old, taken out of a population of 10,155 subjects (4,918 M, 5,237 F; age: 3-56 years old). A structured 4-item questionnaire, direct interview (multistaged), >1 yr follow-up, were used. 9,565 subjects (4,614 M, 4,951 F) sent back the questionnaires, 3,354 of these (1,671 M, 1,683 F) with positive answers to tics. 42 subjects (31 M, 11 F, age: 7-21 years old, mean: 11 years old) met the DSM-III-R criteria. The total minimal prevalence of TS is 0.43%, with a 3:1 ratio male/female. The minimal prevalence of chronic tic disorder is 2.27%. The total minimal prevalence for tic disorders at all is 2.91%. No special education students participation.

ABSTRACT

The purpose of this study was to evaluate whether group psychotherapy was effective in improving of quality of life and would decrease the symptoms of anxiety and depression in Parkinson's disease patients. Sixteen subjects, with idiopathic Parkinson's disease recruited from the school clinical Hospital/UNICAMP. Were randomly divided in to two groups, experimental and control. Parkinson's Disease and Quality of Life - PDQL; Beck Depression Inventory - BDI; State-Trait-Anxiety Inventory - STAI were used to evaluate the patients. The statistical analysis showed significant effect of the interaction group vs. time in depression (0.0009), anxiety (<0.0001) and QuoL (0.0018) and positive changes in depression (0.0029), anxiety (0.0009) and QuoL (0.0047) for the treated group.

ABSTRACT

Pain may precede the diagnosis in Parkinson's disease (PD). The goal of this study was to assess the pain in a group of 20 females and 30 males with PD, after excluding co-morbidities as causes. It was used the following tools: Unified Parkinson's Disease Rating Scale, McGill questionnaire and Beck Depression Inventory. In 27 patients (54%), the pain was associated with PD, occurring in 22 (44%) in the off period and 5 (10%) in both on and off periods. The off period resulted in an increased frequency of pain, which was related to stiffness. There was no association between pain and tremor in off period, neither between pain and Modified Hoehn and Yahr stage, nor the Schwab and England scale. It was not observed an association between pain and depression, neither between pain and dyskinesia. It was noticed the improvement in pain in 16 patients with levodopa (59.26%).

Dor pode preceder o diagnóstico na doença de Parkinson (DP). O objetivo deste estudo foi avaliar a dor num grupo de 20 mulheres e 30 homens com DP. Após a exclusão das co-morbidades como causa. Foi usado o seguinte: Unified Parkinson`s Disease Rating Scale, o questionário de dor McGill e o Inventário de Depressão de Beck. Em 27 pacientes (54 por cento), a dor associou-se com a DP, ocorrendo em 22 (44 por cento) no período off e em 5 (10 por cento) nos períodos on e off. O período off resultou num aumento da freqüência da dor, o qual se relacionou com a rigidez. Não houve associação entre dor e tremor no período off, estágio Hoehn e Yahr modificado, nem a escala de Schwab e England. Não foi observado associação entre dor e depressão, nem entre dor e discinesia. Foi observada a melhora da dor em 16 pacientes com levodopa (59.26 por cento).

ABSTRACT

BACKGROUND: Disorders of water and sodium balance are frequently seen in patients with severe brain injury (SBI), and may worsen their prognosis. PURPOSE: To evaluate vasopressin (AVP) serum levels and sodium and water balance disorders during the first week post-injury in patients with SBI. METHOD: Thirty-six adult patients with SBI (admission Glasgow Coma Scale score < 8) and an estimated time of injury < 72 hours were prospectively studied. Clinical and laboratory data were recorded and AVP was measured in venous blood samples collected on the 1st, 2nd, 3rd and 5th days following inclusion. RESULTS: AVP serum levels remained within the normal range in SBI patients (either traumatic or non-traumatic), although tended to be greater in non-survivor than in survivor patients (p=0.025 at 3rd day). In-hospital mortality was 43 percent (15/36), and serum sodium and plasma osmolality variabilities were greater in non-survivor than in survivor patients during the observation period (p<0.001). CONCLUSION: AVP serum levels remained within the normal range values in these SBI patients, but those who died have shown higher incidence of abnormal sodium and water balance during the first week post-injury.


ANTECEDENTES: Desordens do balanço de água e sódio são frequentemente vistas em pacientes com lesão cerebral grave (LCG), podendo agravar o prognóstico. OBJETIVO: Avaliar os níveis séricos de vasopressina (AVP) e a incidência de distúrbios da água e sódio na primeira semana pós-lesão em pacientes com LCG. MÉTODO: Trinta e seis pacientes adultos com LCG (pontuação inicial na escala de coma de Glasgow < 8) e tempo estimado de lesão < 72h foram estudados prospectivamente. Dados laboratoriais e clínicos foram registrados e os níveis séricos de AVP foram mensurados no 1º, 2º, 3º e 5º dias pós-inclusão. RESULTADOS: A AVP manteve-se dentro da faixa de normalidade nestes pacientes, mas mostrando-se proporcionalmente mais elevada nos pacientes que não sobreviveram (p=0,025 no 3º dia). A mortalidade intra-hospitalar foi 43 por cento (15/36) e as variações do sódio e osmolalidade plasmáticos foram maiores nos pacientes que não sobreviveram durante o período de observação (p<0,001). CONCLUSÃO: Os níveis séricos de AVP mantiveram-se dentro da faixa de normalidade nestes pacientes com LCG, mas aqueles não sobreviventes mostraram maior incidência de anormalidades do balanço de água e sódio durante a primeira semana de evolução.

ABSTRACT

The demonstration of intrathecal antibody production has proven useful for showing the involvement of the central nervous system (CNS) in several diseases. In the present study, the intrathecal synthesis of cysticercus-specific immunoglobulin G (IgG) antibodies was investigated in 30 patients with neurocysticercosis based on calculation of the specific IgG antibody index (AI(IgG)). An AI(IgG) > or =1.5 was considered to be indicative of intrathecal antibody production. Antibody concentrations in serum and cerebrospinal fluid samples were evaluated using an enzyme-linked immunosorbent assay with 2 antigen preparations from Taenia solium cysticerci, namely, a whole cysticercal extract (TsoW) and the vesicular fluid of the parasite (TsoVF). Intrathecal, cysticercus-specific IgG antibody synthesis was observed in 21 (70%) and 23 (76.6%) patients using the TsoW and TsoVF antigens, respectively. The detection of the intrathecal synthesis of specific antibodies may be a potentially useful tool in establishing the involvement of CNS in cysticercosis.

ABSTRACT

Este estudo descreve dados preliminares de eletromiografia laríngea (LEMG) e tratamento com toxina botulínica em pacientes com disfonia associada a distúrbios do movimento. Foram estudados 25 pacientes, 19 com distonia laríngea ou disfonia espasmódica, 5 com tremor vocal e 1 com síndrome de Gilles de la Tourette. LEMG realizada com eletrodos monopolares, antes da administração de toxina botulínica, foi compatível com distonia em 14 pacientes (normal em 5), sugeriu tremor essencial em 3 e Parkinson em 2. Os diferentes padrões de LEMG e melhora considerável obtida com administração de toxina botulínica instituíram LEMG como rotina no ambulatório de distúrbios do movimento da UNICAMP.

ABSTRACT

This study describes preliminary laryngeal electromyography (LEMG) data and botulinum toxin treatment in patients with dysphonia due to movement disorders. Twenty-five patients who had been clinically selected for botulinum toxin administration were examined, 19 with suspected laryngeal dystonia or spasmodic dysphonia (SD), 5 with vocal tremor, and 1 with Gilles de la Tourette syndrome (GTS). LEMG evaluations were performed before botulinum toxin administration using monopolar electrodes. Electromyography was consistent with dystonia in 14 patients and normal in 5, and differences in frequency suggesting essential tremor in 3 and Parkinson tremors in 2. The different LEMG patterns and significant improvement in our patients from botulinum toxin therapy has led us to perform laryngeal electromyography as a routine in UNICAMP movement disorders ambulatory.

ABSTRACT

OBJETIVO: Realizar a normatizaçäo do eletrorretinograma por reversäo alternada em indivíduos oftalmologicamente normais e sem doenças neurológicas associadas, determinando a faixa de normalidade estratificada por sexo, faixa etária e estímulo utilizado. MÉTODOS: A padronizaçäo seguiu o modelo proposto pela Organizaçäo Internacional de Eletrorretinografia e a normatizaçäo foi específica para o laboratório de potenciais evocados do Departamento de Neurologia da Faculdade de Ciências Médicas - Universidade Estadual de Campinas. Dois tipos de estímulos foram utilizados: o denominado estímulo 16, que proporciona ângulo visual de 60 minutos de arco e o de 32, que proporciona ângulo visual de 30. RESULTADOS: Em todos os pacientes obteve-se uma onda positiva, definida internacionalmente como P50 e uma negativa, chamada N95, sem a presença de artefatos. Foram observados intervalos de normalidade que continham a média das latências, amplitudes e duraçöes das curvas positiva e negativa, internacionalmente aceitas. As ondas P50 e N95 apresentaram diferenças significativas na amplitude, latência e duraçäo quando comparadas às diversas faixas etárias, ocorrendo diminuiçäo na amplitude das ondas e aumento na latência total do eletrorretinograma com o aumento da idade. Construíram-se tabelas com intervalo de prediçäo de 95 por cento em relaçäo à idade para a amplitude, latência e duraçäo das curvas P50 e N95. CONCLUSÖES: A normatizaçäo do eletrorretinograma por reversäo alternada proporciona a reprodutibilidade dos resultados e a possibilidade de estudos comparativos

ABSTRACT

Com o intuito de avaliar a utilizaçÝo dos potenciais evocados cerebrais nas manifestaçöes neuropsiquiátricas (MNP) do lúpus eritematoso sistêmico (LES), 27 pacientes näo selecionados para qualquer manifestaçäo clínica foram estudados através de avaliaçäo neurológica, avaliaçÝo neuropsicológica usando o teste Mini-mental State Examination (MMSE). Os potenciais evocados somatossensitivos (PESS), auditivos (PEA) e visuais (PEV) e tomografia computadorizada cerebral (TCC) foram realizados em todos os pacientes. Setenta por cento dos pacientes tinham alguma forma de MNP e 37 por cento, distúrbios neurológicos, principalmente déficit de memória recente, que estava significativamente associado a convulsöes. Atrofia cerebral foi detectada pela TCC em 44 por cento dos casos mas sem correlaçäo com as MNP, potenciais evocados ou testes neuropsicológicos anormais. Os potenciais evocados somatossensoriais foram a mais freqüente alteraçäo neurofisiológica, mas observada apenas em quem tinha sintomas ou déficits neurológicos. Pontenciais evocados visuais alterados ocorreram em quatro pacientes sem sintomas visuais e foram reversíveis. Pontenciais evocados auditivos alterados ocorreram em um único paciente urêmico. Os potenciais evocados podem ser usados no manejo do lúpus neuropsiquiátrico para avaliar as vias sensitivas, auditivas e visuais

ABSTRACT

Monitorizaçäo da pressäo intracraniana (PIC) foi adotada em 100 pacientes com traumatismo cerebral agudo grave, usando-se preferencialmente um catéter subaracnóide. Associaçöes estatísticas foram avaliadas entre valores máximos de PIC e: 1) número de pontos na Escla de Coma de Glasgow (ECG); 2) achados na tomografia computadorizada (TC) da cabeça; e 3) mortalidade. Encontrou-se associaçäo significante entre baixo número de pontos (3 a 5) na ECG e PIC elevada, assim como entre lesöes focais na TC e hipertensäo intracraniana. A mortalidade foi significantemente maior em pacientes com PIC > 40 mm Hg do que naqueles com PIC <=20 mm Hg
