Introdução: O megauretero obstrutivo congénito pode ser tratado por dilatação endoscópica com balão, especialmente nas crianças com menos de um ano de idade. Este trabalho revela a nossa experiência num período de seis anos.
Doentes e métodos: Todos os doentes com o diagnóstico de megauretero obstrutivo congénito submetidos a dilatação endoscópica com balão foram incluídos, no período de tempo compreendido entre 2009 e 2014 (seis anos). O diagnóstico baseou-se na identificação de dilatação do uretero distal superior a 7 mm, padrão obstrutivo no renograma MAG3 e ausência de refluxo vesico-ureteral. Após o diagnóstico, adoptou-se uma atitude conservadora com início de profilaxia antibiótica e vigilância ecográfica em todos os doentes. A indicação cirúrgica resultou de um conjunto de achados clínicos, ecográficos e renográficos. Sob anestesia geral, e após pielografia retrógrada, foi realizada dilatação endoscópica da junção uretero-vesical sob visão directa e controlo fluoroscópico até ao desaparecimento do anel estenótico, colocando-se no final um stent duplo J. O seguimento foi feito com controlo ecográfico e renograma. O sucesso da intervenção cirúrgica foi definido como uma melhoria no grau de hidroureteronefrose (pelo menos 2 graus).
Resultados: No total, 9 doentes foram intervencionados num só uretero, duas meninas e sete meninos, com idade média de 7.6 meses (entre 1-14) na data da cirurgia. Cinco foram no lado esquerdo e quatro no lado direito. Todos os doentes tinham diagnóstico pré-natal de hidroureteronefrose. Nenhum doente foi perdido no seguimento (média 46.7 meses). Todos tinham hidroureteronefrose de grau superior ou igual a 3 e padrão obstrutivo no renograma MAG3. A função relativa média do rim homolateral foi 46.2% (entre 40-53%). A principal indicação cirúrgica foi o agravamento da hidroureteronefrose durante a vigilância ecográfica. Não existiram complicações intra-operatórias. A ecografia mostrou melhoria da hidroureteronefrose em 6 doentes (66.7%). Três doentes foram re-implantados (33.3%) A função relativa média após a cirurgia foi 47.4% (entre 41-53%). Na consulta de seguimento mais recente, todos os doentes estavam assintomáticos.
Discussão: A dilatação endoscópica com balão é uma opção na abordagem do megauretero obstrutivo primário com indicação operatória e pode ser considerado como tratamento de primeira linha nas crianças com menos de um ano de idade.

Objectives: To evaluate urinary stone composition in our institution, its gender and age, including variations and the evolution in the last 7 years.
Material and Methods: The authors reviewed all urinary stone analysis performed since January 2009 to September 2015 in our hospital – Centro Hospitalar do Tâmega e Sousa, Penafiel, Portugal. Patients were stratified by gender, age and stone composition analyzing the evolution of stone composition in different years. The stone analysis method was infrared spectroscopy.
Results: From 302 valid stone analysis reports, 55,3% were female and 44,7% were male patients. Mean patient age was 51±14 years old. A total of 7 different mineral components were identified. 51,6% (n=156) of all the stones had Calcium Oxalate, 41% (n=124) had Calcium Phosphate (33% of Apatite form), 37,7% (n=114) had Uric Acid, 22,1% (n=67) had Ammonium Urate, 9,6% (n=29) had Magnesium Ammonium Phosphate, 6,3% (n=19) had Sodium Urate, and 1,3% (n=4) had Cystine in its composition. Only 30,4% of stones had a single chemical compound. Of these 56% were pure stones of Calcium Oxalate, and 31% were pure stone of Uric Acid. The most frequent mixed stone was Calcium Oxalate + Calcium Phosphate (Apatite) followed by Uric Acid + Ammonium Urate comprehending 45% and 27% of all mixed stones respectively.
Related to the ethology we divided stones into 3 groups, pure non-infection, pure infection, and mixed with component of infection, and the prevalence was 37,7%, 4,3% and 57,9% respectively.
The distribution between genders was similar and the highest difference was in the Ammonium Urate compound with 28% prevalence in male and 17% in women. (p=0,379) Patients after 50 years old had more prevalence of Uric Acid component accounting for 49% of their stones.(p<0,001) .
Along the 7 years of study we identified a significant reduction in the prevalence of mixed stones with component of infection, gradually decreasing from 89,6% in 2009 to 27% in 2015.
Conclusions: Calcium Oxalate calculus were the most prevalent, but this difference was not as important as in other studies worldwide. This study highlights the importance of the development of National and European database to report all regional stone composition variations.

Objetivos Avaliação da razão neutrófilos/linfócitos (RNL) pré-operatória, como fator preditor do risco de recorrência e progressão tumoral em doentes com carcinoma da bexiga não músculo invasivo (CBNMI).
Material e Métodos Análise retrospetiva dos doentes diagnosticados com CBNMI após serem submetidos a ressecção transuretral vesical (RTUV), entre janeiro de 2013 a dezembro de 2014. Foram excluídos os casos que não apresentavam hemograma com leucograma prévio à cirurgia e os doentes com tumores síncronos.
Foi realizada análise estatística multivariada com o software SPSS 22.0®, com as seguintes variáveis: idade, sexo, tempo até ocorrer recorrência ou progressão da doença (em meses), RNL, dimensão do tumor (≤3 ou >3cm), tumor múltiplo, histologia e grau inicial do tumor.
Resultados Foram avaliados 84 pacientes, sendo 79.8% do sexo masculino e com idade média de 69 anos. Em 67,9% dos casos o estadio tumoral inicial foi pTa e 77.4% dos tumores eram de baixo grau. Em 21.4% dos doentes o tumor era múltiplo e em 33.3% apresenta dimensões superiores a 3 cm. Observou-se recorrência tumoral em 19% dos indivíduos e progressão em 16.4%. Os pacientes com RNL>3.32 apresentaram mais frequentemente pT1 como histologia inicial do tumor (p=0.018). Em analise multivariada, a RNL>3.32 revelou estar associada a maior probabilidade de recorrência/progressão tumoral (hazard ratio [HR] = 2.94; 95% CI: 1.27–6.8; p =0. 012).
Conclusões Este estudo revela que a RNL pode ser um fator preditor de recorrência/progressão tumoral em pacientes com CBNMI, podendo ter um papel importante na prática clínica.

In the clinical diagnosis of epilepsy using electroencephalogram (EEG) data, an accurate automatic epileptic spikes detection system is highly useful and meaningful in that the conventional manual process is not only very tedious and time-consuming, but also subjective since it depends on the knowledge and experience of the doctors. In this paper, motivated by significant advantages and lots of achieved successes of deep learning in data mining, we apply Deep Belief Network (DBN), which is one of the breakthrough models laid the foundation for deep learning, to detect epileptic spikes in EEG data. It is really useful in practice because the promising quality evaluation of the spike detection system is higher than $90$\%. In particular, to construct accurate detection model for non-spikes and spikes, a new set of detailed features of epileptic spikes is proposed. These features were then fed to the DBN which is modified from a generative model into a discriminative model to aim at classification accuracy. The experiment results indicate that it is possible to use deep learning models for epileptic spike detection with very high performance in item of sensitivity, selectivity, specificity and accuracy 92.82%, 97.83% , 96.41%, and 96.87%, respectively.

The aim of this study is to select promising wild apricot rootstocks among wild apricot populations propagated by seeds naturally found in Malatya, Erzincan, Nev?ehir, Sivas and Elaz?g provinces. In the first stage, land scans were carried out between 2007 and 2009 and 756 genotypes were determined which could be suitable for the characteristics of the rootstock by considering the phenotypic characteristics. On land surveys, the wild apricot trees that are healthy, productive, bitter seeds, thornless, dwarth growth habit and smooth trunk structure was selected. Among the marked wild apricot types were selected 240 types in 2008, 262 types in 2009 and 254 types in 2010. Seeds taken from these determined wild apricot trees were planted for 2 years in Erzincan and Malatya locations and germination experiments were carried out. In the study, Hasanbey and Hac?halilo?lu apricot varieties were used as control plants. Seed germination percentage, seedling diameter, height, diameter and high homogeneity were determined. At the end of three years of germination experiments were evaluated according to weighting ranking score and finally 8 types that has hight score selected for Malatya location and 18 types for Erzincan location. In the second step, these 26 types after selected in germination tests, was grafted by cv. Hac?halilo?lu in Malatya and by cv. Hasanbey in Erzincan. After grafting success, shoot diameter, homogenity, shoot length and homogenity were evaluated. Then, the data was selected according to weighting ranking score and finally 7 types (58/6, 58/7, 24/111, 24/7, 24/25, 24/33 and 44/8) that has hight score selected for Malatya and Erzincan locations, and transferred to the third stage. In third stage, collection orchards will be established and rootstocks-scion, yield, phenological observations, pomological analysis, tree growth and habit will be evaluated.

La Costa Ecuatoriana alberga diferentes especies de camarones de alta calidad y gran interés comercial, entre ellos destaca el Litopenaeus vannamei debido a su mayor adaptación en la acuacultura. En la amplia gama de mariscos, el camarón cumple el más alto potencial de materia prima cuando se lo transforma en productos que contengan mayor valor agregado debido a sus características organolépticas y excelente calidad, además parte del camarón cosechado o extraído del mar no se exporta, puesto que existe un subproducto que incumple las exigencias de los importadores debido a que se encuentra troceado y se conoce como venta local o camarón quebrado. La enzima transglutaminasa con sus propiedades de ligar proteínas, es un ingrediente clave para reconstituir estos pedazos de bajo valor comercial. El objetivo de este estudio fue desarrollar un producto alimenticio reconstituido a base de pedazos de camarón con una mejor adherencia y compactación en la proteína de la carne del crustáceo. Se evaluó mediante análisis sensorial la aceptabilidad de esta enzima en el producto elaborado, obteniendo mayor preferencia los productos con transglutaminasa por su textura y sabor, cabe destacar que las características organolépticas y el contenido nutricional del camarón no fueron alterados de acuerdo a los análisis realizados.ABSTRACTThe Ecuadorian Coast hosts different species of shrimp of high quality and commercial interest, among them Litopenaeus vannamei stands out due to its greater adaptation in aquaculture. Shrimp fulfills the highest potential of raw material, when it is transformed into products that contain greater added value due to its organoleptic characteristics and excellent quality, in the wide range of seafood. In addition, part of the shrimp harvested or extracted from the sea is not exported, since there is a sub-product that does not meet the requirements of importers because it is cut up and is known as local sale or broken shrimp. The enzyme transglutaminase with its properties of binding protein is a key ingredient to reconstitute these pieces of low commercial value. The objective of this study was to develop a reconstituted food product based on pieces of shrimp with better adhesion and compaction in the crustacean meat protein. The acceptability of this enzyme in the processed product was evaluated by sensorial analysis, obtaining more preference the products with transglutaminase for their texture and flavor, it should be noted that the organoleptic characteristics and the nutritional content of the shrimp were not altered according to the analyzes carried out.
