Acidente vascular cerebral perinatal: 11 casos clínicos

Introdução: Os acidentes vasculares cerebrais (AVC) são causa de epilepsia e perturbações do neurodesenvolvimento. Têm tido uma incidencia crescente atribuível em parte à melhoria das tecnicas de imagens cerebrais. Alguns diagnósticos são efectuados retrospectivamente após o periodo neonatal. O objectivo da presente serie de casos clínicos foi identificar factores comuns que possam facilitar o diagnóstico no período neonatal. Material e métodos: Estudo retrospectivo efectuado com base na consulta dos processos clinicos dos recém-nascidos, com diagnóstico de AVC entre um de Janeiro de 2003 e 31 de Dezembro de 2013. Resultados: Foram identificados onze casos de AVC perinatal, num total 28382 nados-vivos. Dois casos foram diagnosticados no periodo fetal e nove no periodo neonatal. As convulsões foram a manifestação clinica mais frequente (8 em 11 casos). A mediana da idade de diagnóstico foi um dia e variou entre um e nove dias. A ecografia transfontanelar mostrou alterações em sete casos. A ressonancia magnetica nuclear cranio-encefalica mostrou alterações em todos os casos. Cinco AVC foram arteriais isquemicos, quatro hemorragicos e dois tromboses dos seios venosos. Em seis casos foram identificadas possiveis causas. Foram observadas complicações e sequelas em quatro dos casos. Discussão: As convulsões foram a manifestação clinica mais frequentemente encontrada.Em recém-nascidos de termo com convulsões sem historia de asfixia intraparto o AVC perinatal deverá ser diagnóstico de exclusão, mesmo na ausencia de alterações na ecografia transfontanelar.

Papel del peritoneo en el cierre de la pared abdominal en animales de experimentación

Parte de la necesidad de conocer técnicas para la sutura de una herida que brinden seguridad y eviten complicaciones en el manejo de los pacientes durante el pos operativo. Analiza algunas técnicas y al término de este trabajo experimental en perros, el no suturar el peritoneo parietal luego de una laparotomía con incisión en la línea media supraumbilical indica las siguientes ventajas: 1. Disminución en la frecuencia, consistencia y tamaño de las adherencias; 2. Reacción tisular inflamatoria leve; 3. Se disminuye la presencia de focos isquémicos; 4. Mejor exposición para la sutura del plano aponeurótico; 5. Cierre de la pared abdominal en un menor tiempo disminuyendo la exposición a la anestesia; 6. Disminuye la cantidad de material de sutura a utilizarse y el costo que representa. Recomienda que estos resultados obtenidos experimentalmente en perros, por la diferencia de la especie no se puede aplicar directamente a los seres humanos, a pesar de la similitud en la respuesta inflamatoria al daño tisular, pero en vista de las ventajas que nos da esta técnica en el cierre de la pared abdominal, se podría realizar futuros estudios en humanos con similar orientación

Estudio comparativo de la síntesis de pared abdominal entre la técnica de Tom Jones y el Cierre Anatómico por Planos

Con el propósito de estudiar comparativamente dos técnicas diferentes de sutura en pared abdominal, y cuyos resultados obtenidos demuestren generosidad o defecto en una u otra, veinte perros machos de raza criolla, (fotos) con una edad y peso promedio de 3,4 años y 9kg. Respectivamente fueron intervenidos quirúrgicamente bajo anestesia general conpenthotal endovenenosa y una técnica operatoria aséptica realizándose laparotomía supraumbilical media desde el apéndice xifoides hasta el ombligo (fotos) y sutura de la pared abdominal con técnica de Tom Jones en diez de ellos y sutura por planos en la otra mitad. La sutura de Tom Jones en el estudio experimental es superior a la sutura por planos porque: 1. Produce menos adherencias; 2. La inflamación que produce en los tejidos es menor; 3. La consistencia de las adherencias y su tamaño son menores; 4. Es una sutura que resiste más a la ruptura de las heridas

Know-cap: um método para capitalização de conhecimento no desenvolvimento de software

The intensive character in knowledge of software production and its rising demand suggest the need to establish mechanisms to properly manage the knowledge involved in order to meet the requirements of deadline, costs and quality. The knowledge capitalization is a process that involves from identification to evaluation of the knowledge produced and used. Specifically, for software development, capitalization enables easier access, minimize the loss of knowledge, reducing the learning curve, avoid repeating errors and rework. Thus, this thesis presents the know-Cap, a method developed to organize and guide the capitalization of knowledge in software development. The Know-Cap facilitates the location, preservation, value addition and updating of knowledge, in order to use it in the execution of new tasks. The method was proposed from a set of methodological procedures: literature review, systematic review and analysis of related work. The feasibility and appropriateness of Know-Cap were analyzed from an application study, conducted in a real case, and an analytical study of software development companies. The results obtained indicate the Know- Cap supports the capitalization of knowledge in software development.

A contribution to semantic description of images and videos: an application of soft biometrics

Humans have a high ability to extract visual data information acquired by sight. Trought a learning process, which starts at birth and continues throughout life, image interpretation becomes almost instinctively. At a glance, one can easily describe a scene with reasonable precision, naming its main components. Usually, this is done by extracting low-level features such as edges, shapes and textures, and associanting them to high level meanings. In this way, a semantic description of the scene is done. An example of this, is the human capacity to recognize and describe other people physical and behavioral characteristics, or biometrics. Soft-biometrics also represents inherent characteristics of human body and behaviour, but do not allow unique person identification. Computer vision area aims to develop methods capable of performing visual interpretation with performance similar to humans. This thesis aims to propose computer vison methods which allows high level information extraction from images in the form of soft biometrics. This problem is approached in two ways, unsupervised and supervised learning methods. The first seeks to group images via an automatic feature extraction learning , using both convolution techniques, evolutionary computing and clustering. In this approach employed images contains faces and people. Second approach employs convolutional neural networks, which have the ability to operate on raw images, learning both feature extraction and classification processes. Here, images are classified according to gender and clothes, divided into upper and lower parts of human body. First approach, when tested with different image datasets obtained an accuracy of approximately 80% for faces and non-faces and 70% for people and non-person. The second tested using images and videos, obtained an accuracy of about 70% for gender, 80% to the upper clothes and 90% to lower clothes. The results of these case studies, show that proposed methods are promising, allowing the realization of automatic high level information image annotation. This opens possibilities for development of applications in diverse areas such as content-based image and video search and automatica video survaillance, reducing human effort in the task of manual annotation and monitoring.

Adsorção de corantes têxteis aniônicos e catiônicos em resíduos do processamento de fios de algodão modificados quimicamente

The textile industry generates a large volume of high organic effluent loading whoseintense color arises from residual dyes. Due to the environmental implications caused by this category of contaminant there is a permanent search for methods to remove these compounds from industrial waste waters. The adsorption alternative is one of the most efficient ways for such a purpose of sequestering/remediation and the use of inexpensive materials such as agricultural residues (e.g., sugarcane bagasse) and cotton dust waste (CDW) from weaving in their natural or chemically modified forms. The inclusion of quaternary amino groups (DEAE+) and methylcarboxylic (CM-) in the CDW cellulosic structure generates an ion exchange capacity in these formerly inert matrix and, consequently, consolidates its ability for electrovalent adsorption of residual textile dyes. The obtained ionic matrices were evaluated for pHpcz, the retention efficiency for various textile dyes in different experimental conditions, such as initial concentration , temperature, contact time in order to determine the kinetic and thermodynamic parameters of adsorption in batch, turning comprehensive how does occur the process, then understood from the respective isotherms. It was observed a change in the pHpcz for CM--CDW (6.07) and DEAE+-CDW (9.66) as compared to the native CDW (6.46), confirming changes in the total surface charge. The ionized matrices were effective for removing all evaluated pure or residual textile dyes under various tested experimental conditions. The kinetics of the adsorption process data had best fitted to the model a pseudosecond order and an intraparticle diffusion model suggested that the process takes place in more than one step. The time required for the system to reach equilibrium varied according to the initial concentration of dye, being faster in diluted solutions. The isotherm model of Langmuir was the best fit to the experimental data. The maximum adsorption capacity varied differently for each tested dye and it is closely related to the interaction adsorbent/adsorbate and dye chemical structure. Few dyes obtained a linear variation of the balance ka constant due to the inversion of temperature and might have influence form their thermodynamic behavior. Dyes that could be evaluated such as BR 18: 1 and AzL, showed features of an endothermic adsorption process (ΔH° positive) and the dye VmL presented exothermic process characteristics (ΔH° negative). ΔG° values suggested that adsorption occurred spontaneously, except for the BY 28 dye, and the values of ΔH° indicated that adsorption occurred by a chemisorption process. The reduction of 31 to 51% in the biodegradability of the matrix after the dye adsorption means that they must go through a cleaning process before being discarded or recycled, and the regeneration test indicates that matrices can be reused up to five times without loss of performance. The DEAE+-CDW matrix was efficient for the removal of color from a real textile effluent reaching an UV-Visible spectral area decrease of 93% when applied in a proportion of 15 g ion exchanger matrix L-1 of colored wastewater, even in the case of the parallel presence of 50 g L-1 of mordant salts in the waste water. The wide range of colored matter removal by the synthesized matrices varied from 40.27 to 98.65 mg g-1 of ionized matrix, obviously depending in each particular chemical structure of the dye upon adsorption.
