Intervenção dietoterápica em portadores de lipodistrofia generalizada congênita do Rio Grande do Norte

Congenital generalized lipodystrophy is a rare genetic disease with autosomal recessive inheritance characterized by the generalized absence of subcutaneous adipose tissue and insulin resistance. The aim of our study was to determine the profile of patients with congenital generalized lipodystrophy (Berardinelli-Seip syndrome) through their clinical history, eating habits, and socioeconomic and cultural aspects; assess food consumption and nutritional status of the study group; propose and evaluate a diet therapy model associated to oral supplementation with zinc to help in the control and prevention of metabolic complications associated to the pathology. Initial assessment of food consumption indicated a voracious appetite in all the patients studied. The introduction of zinc reduced appetite, contributing to patient adherence to the food plan proposed. It was also observed that the proposed diet contributed mainly to glycidic control, specifically with respect to HbA1c. The nutritional status of the patients investigated was adequate in terms of body mass index (BMI), arm muscle circumference (AMC), arm muscle area AMA, but triceps skinfold (TSF) indicated serious malnutrition. Our study is unique in the literature and provides important information to the field of nutrition and to individuals with this pathology. Furthermore, it contemplates the interdisciplinary and multidisciplinary requirements of the Postgraduate Program in Health Sciences of the Federal University of Rio Grande do Norte (UFRN), Natal, Brazil

A prática de atividade física de crianças e adolescentes com e sem epilepsia

The epilepsy is one of the neurological disorders more common in the pediatric period, and which interferes significantly in the psycho and social life of children and teenagers. The objective of this study was analyzing the practice of sedentary practices, physicals, traditional infant fun and games of children and teenagers with and without epilepsy. The study was prospective, transversal descriptive, done with 60 children and teenagers with epilepsy (Epileptic Group - EG) patients from Pediatric Neurology Clinic of the Centre Integrated Health Lineu Araújo and 60 children and teenagers without epilepsy (Control Group - CG) students from municipal public school, both of the two groups paired with the same age (age group 7 to 14 years) of both the genders (female = 25/41,6% and male = 35/58,3%) of the Teresina city Piauí. It was done two pattern questionnaires, one applied to children and teenagers of the EG and CG to identify the sedentary activities, physical and traditional infant games and other to the parents/responsible of the EG about the clinical and demographic information. The results permitted the elaboration of two manuscripts: a) the first one titled The Practice of Sedentary and Physical Activities of Children and Teenagers with Epilepsy which showed significant difference in the sedentary activities of playing with car toy (p=0,021) to the EG and reading to the CG (p=0,001); in the physical activities the school physical education (p=0,001) and riding a bike (p=0,014) to the CG; b) the second one The Practice of Infant Games and Fun the children and teenagers with and without Epilepsy in this one the playing with marble presented significant difference (p=0,016) to the CG, despite the girls of the two groups don t do this activity. Observing the distribution of frequencies, it was verified that in the play catch-up and hide-and-seek and burn the EG plays more than the CG both in female and male gender. The girls of the EG play less skip, 60 while the boys of the two groups don t play. Elastic jump the girls of the two groups play in a same frequency and the boys don t participate of this fun. The seizures were found to occur during: soccer (23,3%); hide-and-seek (6,6%) and running (3,3%). In the sedentary activities, seizures were reported to occur: resting and watching TV (18,3%), sleeping (36,0%); sitting (13,3%) and lying down (11,7%). Our results showed that the epileptic group and the controls group engage in the same activities, although the epileptic group participates less than the controls. Although the EG had presented a bigger percentage of generalized attacks, they don t occur during the practice of formal physical activities. The research was developed by a multidisciplinary team, and this contributed a lot to the realization of this study

ANÁLISE COMPARATIVA DO CONHECIMENTO, ATITUDES E PRECONCEITOS DE UNIVERSITÁRIOS DOS CURSOS DE PEDAGOGIA, EDUCAÇÃO FÍSICA E MEDICINA EM RELAÇÃO À EPILEPSIA

Epilepsy is a chronic disorder of the central nervous system, most frequently characterized by abnormal electrical impulses in the brain. It is the oldest recorded neurological disease and has been surrounded by myths, mistaken beliefs and preconceptions. Three professionals work with epileptic patients on a daily basis: teachers, physical educators and physicians . This study aimed to analyze and compare the level of knowledge, preconceptions and attitudes of undergraduate students in the courses of Pedagogy, Physical Education and Medicine, future professionals who will deal with epileptic patients. This descriptive observational study was conducted with 286 university undergraduates of both sexes (women 99/34.6% and men 187/65.4%) from the first to fourth year of Pedagogy, Physical Education and Medicine courses at the Universidade Estadual Rio Grande do Norte (UERN), with mean age of 23 years. A validated and adapted 17-question questionnaire, divided into nine knowledge-based questions, five related to preconceptions and three on attitudes, was applied. Results allowed elaboration of a manuscript entitled Comparative Analysis of Knowledge, Attitude and Preconceptions in University Undergraduates of Pedagogy, Physical Education and Medicine Courses in Relation to Epilepsy. The findings of this article show that knowledge of epilepsy in the three groups is very satisfactory. The low level of preconception indicates that educational or clarifying information is being transmitted, albeit by television, a layman s information vehicle, which has undoubtedly contributed to reducing the stigma of epilepsy through educational information. Results also suggest a lack of knowledge on how to act during a seizure, especially in education professionals. Although there are limitations in our sample, the relevance and contribution of this study is to call attention to the importance and need for these future professionals to be informed and learn correct attitudes with respect to epilepsy during their academic formation. This is essential at a time when the disease is being brought out of the shadows. This research was supported by the Office of the Dean of Teaching, and Deans of Pedagogy, Physical Education and Medicine at UERN. The research was made possible by the multidisciplinary interaction among a physical educator, child neurologist and statistician, all contributing to achieving the aims set out here

Função de distribuição generalizada aplicada à velocidade de rotação estelar

In the present work we use a Tsallis maximum entropy distribution law to fit the observations of projected rotational velocity measurements of stars in the Pleiades open cluster. This new distribution funtion which generalizes the Ma.xwel1-Boltzmann one is derived from the non-extensivity of the Boltzmann-Gibbs entropy. We also present a oomparison between results from the generalized distribution and the Ma.xwellia.n law, and show that the generalized distribution fits more closely the observational data. In addition, we present a oomparison between the q values of the generalized distribution determined for the V sin i distribution of the main sequence stars (Pleiades) and ones found for the observed distribution of evolved stars (subgiants). We then observe a correlation between the q values and the star evolution stage for a certain range of stel1ar mass

Caracterização estatística de processos sísmicos via Distribuição Generalizada de Pareto. Estudo de caso: João Câmara-RN

The work is to make a brief discussion of methods to estimate the parameters of the Generalized Pareto distribution (GPD). Being addressed the following techniques: Moments (moments), Maximum Likelihood (MLE), Biased Probability Weighted Moments (PWMB), Unbiased Probability Weighted Moments (PWMU), Mean Power Density Divergence (MDPD), Median (MED), Pickands (PICKANDS), Maximum Penalized Likelihood (MPLE), Maximum Goodness-of-fit (MGF) and the Maximum Entropy (POME) technique, the focus of this manuscript. By way of illustration adjustments were made for the Generalized Pareto distribution, for a sequence of earthquakes intraplacas which occurred in the city of João Câmara in the northeastern region of Brazil, which was monitored continuously for two years (1987 and 1988). It was found that the MLE and POME were the most efficient methods, giving them basically mean squared errors. Based on the threshold of 1.5 degrees was estimated the seismic risk for the city, and estimated the level of return to earthquakes of intensity 1.5°, 2.0°, 2.5°, 3.0° and the most intense earthquake never registered in the city, which occurred in November 1986 with magnitude of about 5.2º

Revisitando o eletrocorticograma intra-operatório na epilepsia mesial do lobo temporal: relevância das oscilações de alta frequência

Epilepsies are neurological disorders characterized by recurrent and spontaneous seizures due to an abnormal electric activity in a brain network. The mesial temporal lobe epilepsy (MTLE) is the most prevalent type of epilepsy in adulthood, and it occurs frequently in association with hippocampal sclerosis. Unfortunately, not all patients benefit from pharmacological treatment (drug-resistant patients), and therefore become candidates for surgery, a procedure of high complexity and cost. Nowadays, the most common surgery is the anterior temporal lobectomy with selective amygdalohippocampectomy, a procedure standardized by anatomical markers. However, part of patients still present seizure after the procedure. Then, to increase the efficiency of this kind of procedure, it is fundamental to know the epileptic human brain in order to create new tools for auxiliary an individualized surgery procedure. The aim of this work was to identify and quantify the occurrence of epilepticform activity -such as interictal spikes (IS) and high frequency oscillations (HFO) - in electrocorticographic (ECoG) signals acutely recorded during the surgery procedure in drug-resistant patients with MTLE. The ECoG recording (32 channels at sample rate of 1 kHz) was performed in the surface of temporal lobe in three moments: without any cortical resection, after anterior temporal lobectomy and after amygdalohippocampectomy (mean duration of each record: 10 min; N = 17 patients; ethic approval #1038/03 in Research Ethic Committee of Federal University of São Paulo). The occurrence of IS and HFO was quantified automatically by MATLAB routines and validated manually. The events rate (number of events/channels) in each recording time was correlated with seizure control outcome. In 8 hours and 40 minutes of record, we identified 36,858 IS and 1.756 HFO. We observed that seizure-free outcome patients had more HFO rate before the resection than non-seizure free, however do not differentiate in relation of frequency, morphology and distribution of IS. The HFO rate in the first record was better than IS rate on prediction of seizure-free patients (IS: AUC = 57%, Sens = 70%, Spec = 71% vs HFO: AUC = 77%, Sens = 100%, Spec = 70%). We observed the same for the difference of the rate of pre and post-resection (IS: AUC = 54%, Sens = 60%, Spec = 71%; vs HFO: AUC = 84%, Sens = 100%, Spec = 80%). In this case, the algorithm identifies all seizure-free patients (N = 7) with two false positives. To conclude, we observed that the IS and HFO can be found in intra-operative ECoG record, despite the anesthesia and the short time of record. The possibility to classify the patients before any cortical resection suggest that ECoG can be important to decide the use of adjuvant pharmacological treatment or to change for tailored resection procedure. The mechanism responsible for this effect is still unknown, thus more studies are necessary to clarify the processes related to it

Avaliação dos níveis de proteína C-reativa ultra-sensível em pacientes com periodontite crônica severa generalizada e sem periodontite

INTRODUCTION: The high sensitivity C-reactive protein (hsCRP) constitutes an inflammatory mediator used as predictor of cardiovascular risk that comes being researched as indicative relation factor between cardiovascular and periodontal diseases. PROPOSITION: To compare serumals levels of C-reactive protein between patients with and without generalized severe chronic periodontitis. METHODOLOGY: A seccional study was realized using a sample with 62 patients, being 31 participants carriers of periodontal diseases (Group I) and 31 without periodontal diseases (Group II), grouped to the pairs by age and sex. As inclusion criterio were selected patients with diagnosis of generalized severe chronic periodontitis, being preculeds, individuals which presented systemic disease, recent infection history, historical of CVA or stroke, smokers, pregnants and lactants. The research consisted of two stages, a clinc and other biochemist. The clinical stage is constituted of periodontal examination and the biochemist stage, of the peripheral blood collection for determination hsCRP levels and a hemogram to inquire any panel which could suggest infectious and/or inflammatory process. RESULTS: Periodontal disease group presented a average of 0,36mg/dL, while the group without disease presented 0,17 mg/dL, do not existing significant difference statistically between the averages (p = 0,061). The cardiovascular risk for the group I was classified high for 27,6% of participants and low for 72,4% of them. In the group II, 6,45% presented high risk e 93,5% low risk, being this significant relation statistically gotten for Fisher s Test (p = 0,042) presenting OR = 5,33; IC = 95% (1,02 27,4). The independets variables reseacred do not presented significant association statistically with the levels of hsCRP. CONCLUSION: The study indicated that despite of carriers patients of periodontal diseases do not present differents serumals levels of hsCRP from the other group, the periodontal disease was considered as risk factor for hsCRP plasmatic levels elevation

Estudo da excreção urinária de cálcio, potássio e sódio com o emprego de citrato de potássio na hipercalciúria idiopática na criança

OBJETIVO: Estudar as relações entre a excreção urinária de cálcio, sódio e potássio e a associação sódio/potássio urinários em crianças com hipercalciúria idiopática em dieta habitual, antes e depois da administração de citrato de potássio na dose de 1mEq/kg/dia. MÉTODOS: Foram estudadas prospectivamente 26 crianças: 19 (73%) meninos e sete (27%) meninas com idade entre dois e 13 anos, portadores de hipercalciúria idiopática recém-diagnosticada por dosagem de cálcio em urina de 24 horas >4mg/kg/dia. O citrato de potássio foi administrado na dose de 1mEq/kg/dia. Foram realizadas dosagens séricas e em urina de 24 horas de cálcio (Ca), potássio(K), sódio (Na) e creatinina (Cr), antes e 15 dias depois da administração diária do citrato de potássio. Para comparar os resultados de cálcio/creatinina (Ca/Cr), potássio/creatinina (K/Cr) e sódio/potássio (Na/K) urinários nos dois momentos, aplicou-se o teste não-paramétrico de Wilcoxon. Para a análise das associações entre Ca/Cr e K/Cr e entre Ca/Cr e Na/Cr foi utilizado o coeficiente de correlação de Pearson. Considerou-se significante p<0,05. RESULTADOS: Após o uso de citrato de potássio, ocorreu significativa redução da calciúria e da relação Na/K urinários, bem como elevação na caliúria. Não houve modificação da excreção urinária de sódio. CONCLUSÕES: em dieta habitual, o citrato de potássio eleva a caliúria e diminui a calciúria em criança hipercalciúricas, sendo um eficaz recurso terapêutico.

Avaliação tomográfica dos pedículos vertebrais no tratamento cirúrgico dos pacientes com escoliose idiopática do adolescente

OBJETIVO: Determinar através de cortes tomográficos e reconstrução tridimensional a incidência de mal posicionamento de parafusos em pacientes submetidos ao tratamento cirúrgico da Escoliose idiopática do adolescente. MÉTODOS: Foram analisados exames tomográficos de 8 pacientes, tratados cirurgicamente no Hospital de Base de São José do Rio Preto-SP, realizada instrumentação posterior partindo de T2 /T4 a L4/L5 totalizando 164 parafusos. RESULTADOS: 32,9% (n=54) apresentavam posicionamento com risco potencial,ou seja desvio acima de 2 milímetros, sendo 20,1% (n=33) com invasão lateral, 9,1% (n=15) com invasão medial, 3,6 %(n=6) com invasão anterior. Dos parafusos que ofereciam risco potencial a relação com aspecto da curva foi de 46% (n=25) na concavidade, 35% (n=19) na convexidade e 19% (n=10) em vértebras adjacentes a curva. CONCLUSÃO: Os limites de penetração aceitáveis, assim como os métodos de mensuração ainda não foram padronizados, a técnica free hand' mostrou-se segura, apesar da violação dos pedículos. A tomografia computadorizada pré-operatória, auxilia no planejamento cirúrgico e na redução das complicações.

Aspectos físicos e mentais na qualidade de vida de pacientes com doença de Parkinson idiopática

A doença de Parkinson (DP) é um distúrbio crônico e progressivo, caracterizado pela degeneração de neurônios dopaminérgicos da substantia nigra mesencefálica. A lesão das vias subcorticais, em especial a nigro-estriato-palidal, é particularmente comum e ocasiona uma série de sinais e sintomas incapacitantes. O objetivo deste trabalho foi analisar a qualidade de vida (QV) relacionada à saúde de sujeitos com DP e compará-la à de indivíduos controles saudáveis. Foram avaliados 40 sujeitos com idades entre 61 e 83 anos, de ambos os sexos, que foram divididos em dois grupos: grupo Parkinson (n=21), composto por sujeitos com DP idiopática, e grupo controle (n=19), de indivíduos sem distúrbios neurodegenerativos. Para a coleta de dados, foi utilizada a versão brasileira do questionário Brasil SF-36. Os resultados foram analisados estatisticamente, com nível de significância fixado em 1%. Os sujeitos do grupo Parkinson apresentaram escores significativamente mais baixos do que os do grupo controle, tanto no domínio físico quanto no mental, medidos pelo SF-36. Essa baixa QV provavelmente é explicada pela co-ocorrência de fenômenos neurodegenerativos e do sofrimento psíquico gerado pela doença e pelo estigma que ela produz. Abordagens interdisciplinares devem ser estimuladas a pacientes com DP, com o objetivo de melhorar sua qualidade de vida e postergar o declínio físico e mental inerente às condições degenerativas.

Estimativa da probabilidade do evento extremo de precipitação de janeiro de 2000 no Vale do Paraíba, baseada na distribuição generalizada de pareto

Um evento extremo de precipitação ocorreu na primeira semana do ano 2000, de 1º a 5 de janeiro, no Vale do Paraíba, parte leste do Estado de São Paulo, Brasil, causando enorme impacto socioeconômico, com mortes e destruição. Este trabalho estudou este evento em 10 estações meteorológicas selecionadas que foram consideradas como aquelas tendo dados mais homogêneos do Que outras estações na região. O modelo de distribuição generalizada de Pareto (DGP) para valores extremos de precipitação de 5 dias foi desenvolvido, individualmente para cada uma dessas estações. Na modelagem da DGP, foi adotada abordagem não-estacionaria considerando o ciclo anual e tendência de longo prazo como co-variaveis. Uma conclusão desta investigação é que as quantidades de precipitação acumulada durante os 5 dias do evento estudado podem ser classificadas como extremamente raras para a região, com probabilidade de ocorrência menor do que 1% para maioria das estações, e menor do que 0,1% em três estações.

Avaliação da ingestão dietética de cálcio em indivíduos adultos portadores de hipertensão arterial idiopática

Foi estudada a relação entre a ingestão dietética de cálcio e os demais parâmetros alimentares e antropométricos em 60 indivíduos adultos, portadores de hipertensão arterial idiopática (10 homens e 50 mulheres), com média etária de 48,6 anos, seguidos no Centro de Hipertensão Arterial do Hospital das Clínicas da Faculdade de Medicina de Botucatu (SP), Brasil. Foram utilizados três métodos diferentes de inquérito aumentar em três diferentes ocasiões: recordatório de 24h, questionário de freqüência alimentar, dirigido para ingestão de cálcio, e registro alimentar de 3 dias. As médias de ingestão de cálcio, extraídas desses inquéritos, foram semelhantes, mostrando que, em relação á ingestão de cálcio, esses métodos de inquérito alimentar podem ser utilizados indistintamente com o objetivo de se mensurar à ingestão de cálcio de um grupo de indivíduos. Além da ingestão de cálcio, foi avaliada a ingestão protéico-calórica e de diversos outros nutrientes, assim como realizada a antropometria desse grupo de hipertensos em três ocasiões diferentes, com intervalos variando de duas semanas a 15 meses. Quando comparado a um grupo de referência local, constituído de indivíduos sadios, com média etária semelhante, o grupo de hipertensos mostrou ter menor ingestão média de cálcio. Comparados por sexo, os homens dos dois grupos exibiram perfis nutricional e antropométrico semelhantes. em relação às mulheres, houve diferenças quanto à ingestão protéico-calórica, o que se supõe ser devido à ingestão menor do leite e derivados entre as hipertensas. Estas estavam mais pesadas que as mulheres do grupo de referências, à custa de maior massa muscular, provavelmente devido a maior atividade física. Concluiu-se que o cálcio dietético foi o principal item alimentar que distinguiu hipertensos de normotensos. Como existem estudos clínicos comprovando o efeito benéfico da suplementação de cálcio na redução dos níveis pressóricos de indivíduos hipertensos, sugere-se a repetição deste tipo de trabalho, em outros locais, visando ao embasamento de programa nacional de suplementação de cálcio dietético entre indivíduos hipertensos idiopáticos.
