Feasibility of Focal Transcranial DC Polarization with Simultaneous EEG Recording: Preliminary Assessment in Healthy Subjects and Human Epilepsy

We aimed to investigate the feasibility of an experimental system for simultaneous transcranial DC stimulation(tDCS) and EEG recording in human epilepsy. We report tolerability of this system in a cross-over controlled trial with 15 healthy subjects and preliminary effects of its use, testing repeated tDCS sessions, in two patients with drug-refractory Continuous Spike-Wave Discharges During Slow Sleep (CSWS). Our system combining continuous recording of the EEG with tDCS allows detailed evaluation of the interictal activity during the entire process. Stimulation with 1 mA was well‐tolerated in both healthy volunteers and patients with refractory epilepsy. The large reduction in interictal epileptiform EEG discharges in the two subjects with epilepsy supports further investigation of tDCS using this combined method of stimulation and monitoring in epilepsy. Continuous monitoring of epileptic activity throughout tDCS improves safety and allows detailed evaluation of epileptic activity changes induced by tDCS in patients.

Potential immunological markers for diagnosis and therapeutic assessment of toxocariasis

In human toxocariasis, there are few approaches using immunological markers for diagnosis and therapeutic assessment. An immunoblot (IB) assay using excretory-secretory Toxocara canis antigen was standardized for monitoring IgG, IgE and IgA antibodies in 27 children with toxocariasis (23 visceral, three mixed visceral and ocular, and one ocular form) for 22-116 months after chemotherapy. IB sensitivity was 100% for IgG antibodies to bands of molecular weight 29-38, 48-54, 95-116, 121-162, >205 kDa, 80.8% for IgE to 29-38, 48-54, 95-121, > 205 kDa, and 65.4% for IgA to 29-38, 48-54, 81-93 kDa. Candidates for diagnostic markers should be IgG antibodies to bands of low molecular weight (29-38 and 48-54 kDa). One group of patients presented the same antibody reactivity to all bands throughout the follow-up study; in the other group, antibodies decayed partially or completely to some or all bands, but these changes were not correlated with time after chemotherapy. Candidates for monitoring patients after chemotherapy may be IgG antibodies to > 205 kDa fractions, IgA to 29-38, 48-54, 81-93 kDa and IgE to 95-121 kDa. Further identification of antigen epitopes related to these markers will allow the development of sensitive and specific immunoassays for the diagnosis and therapeutic assessment of toxocariasis.

Assessment of physical impairments in leprosy patients: a comparison between the world health organization (who) disability grade and the Eye-Hand-Foot Score

This cross-sectional study assessed the grade of physical impairments in 61 individuals with leprosy receiving multidrug therapy (MDT) under the Brazilian Unified Health System (SUS), and residing in Campina Grande, Paraíba State, Brazil. Impairments were assessed using the disability grade (DG) standardized by the WHO, and the EHF score (Eye-Hand-Foot sum of impairment scores). Impairments were detected in 25 (41%) of the subjects. A total of 14 (23%) patients scored DG 1, while 11 (18%) were assigned DG 2. The EHF score ranged from 1 to 10 points in the group of patients with physical impairments, with a mean score of 3.6 points. The majority of individuals with impairments were affected in at least two sites. We conclude that the EHF score showed overlapping impairments in the segments examined and may be more appropriate than the DG classification system for describing the degree of physical impairment of leprosy patients.

Análise de estabilidade e fundações de equipamentos de sinalização vertical rodoviária

O presente projeto foi realizado no âmbito da unidade curricular Dissertação/Estágio/Projeto, e desenvolve um estudo sobre as estruturas porticadas de sinalização vertical em Autoestradas, ao nível da estrutura metálica e das fundações, com o objetivo de analisar três casos diferentes com características distintas. Dois dos casos em estudo são modelos comuns que se encontram facilmente nas autoestradas. O terceiro tem uma configuração diferente, mais gravoso que o habitual. Com estes três casos obtém-se um estudo completo e abrangente deste tipo de estrutura porticada. Ao longo do projeto é seguida a norma EC3 (Eurocódigo 3 – Projeto de estruturas de aço). Dimensionaram-se as estruturas utilizando secções tubulares, mas é também realizado o dimensionamento de uma solução estrutural alternativa recorrendo a perfis laminados I ou H. As estruturas foram modeladas com recurso ao software de cálculo Autodesk Robot Structural Analysis Professional, obtendo-se os esforços e deformações nos vários pontos da estrutura, que permitem realizar o dimensionamento manual das secções dos perfis estruturais, chumbadouros, chapas de fundação e fundações propriamente ditas. Na parte final do projeto apresenta-se uma apreciação global do mesmo, conclusões gerais sobre os resultados obtidos e possíveis desenvolvimentos futuros.
