Metástase hipofisária de adenocarcinoma mamário: relato de caso / Pituitary Metastasis of Mammary Adenocarcinoma: A Case Report

Somente 1% de todas as cirurgias hipofisárias são realizadas para tratar tumores metastáticos desta região. Os focos primários mais comuns são respectivamente mama e pulmão. Neste artigo, descrevemos uma paciente com antecedente de adenocarcinoma mamário, que se apresenta com paralisia oculomotora súbita à direita. O objetivo do trabalho é descrever um caso de metástase mamária para a região selar, evidenciando dados clínicos e radiológicos que tornam tal diagnóstico plausível.

Only 1% of all pituitary surgeries are performed to treat metastatic tumors in this region. The most common primary sites are breast and lung respectively. In this article we describe a patient with previous breast adenocarcinoma presenting with oculomotor palsy sudden right. The objective is to describe a case of breast metastasis to the sellar region, showing clinical and radiological findings that make this plausible diagnosis.

Estudo da identidade histológica de subprodutos de soja (Glycine max L. ) / Study on the histological identity of soy products (Glycine max L. )

A partir do grão de soja são obtidos diversos subprodutos, tais como farinha, farelo, proteína texturizada e óleo, constantemente utilizados em formulações de alimentos como biscoitos, pães, chocolates, entre outros. Durante o processamento, a estrutura da soja pode ser alterada, de forma a impossibilitar a identificação histológica deste vegetal nos produtos alimentícios. Este trabalho teve como objetivo identificar as características histológicas de diferentes subprodutos de soja. Amostras de proteína texturizada de soja, proteína de soja desengordurada, proteína isolada de soja e proteína de soja concentrada foram cedidas por uma indústria processadora de soja. Estas amostras foram submetidas à análise histológica, seguindo-se os Métodos Oficiais do Instituto Adolfo Lutz, para verificação da presença dos elementos histológicos característicos. Dentre os quatro subprodutos analisados, somente a proteína isolada de soja não apresentou elementos histológicos característicos. A proteína de soja concentrada apresentou menor quantidade de elementos histológicos em relação à proteína texturizada de soja e à proteína de soja desengordurada. Estes achados contribuirão para a análise de produtos à base de soja no que se refere à sua composição, a fim de identificar possíveis fraudes ou contaminações.

From the soya beans are obtained various by-products such as flour, meal, textured protein and oil, which are regularly used in food formulations such as cookies, breads, chocolates, among others. During the food processing, the soya structure might be changed, and turning into hard to perform the histological identification of this vegetable in the food products. This study aimed at identifying the histological characteristics of different soy sub-products. Textured soy protein, defatted soy protein, soy-isolated protein and concentrated soy protein samples were provided by a soybean processor industry. These samples were investigated by means of histological analysis, according to the Official Methods of the Instituto Adolfo Lutz for detecting the presence of the characteristic histological elements. Among the four analyzed sub-products, the isolated soy protein only showed no characteristic histological elements. The concentrated soy protein showed the lowest amounts of histological elements in relation to the textured soy protein and the defatted soy protein. These findings will contribute to the soya-based products analyses concerning their composition, in order to identify the potential fraud or contamination.

Monitoring the extraneous matters in pulps of tomato, guava, mango and strawberry marketed during the seasons of the year

Fruit-derived products sold in Brazil and for exportation are required to comply with the quality and safety standards. These products and, among them, the fruit pulps may contain extraneous materials due to the inappropriate conditions or practices during their production, storage and distribution, including filth, decomposed material and miscellaneous materials. This study aimed at evaluating the sanitary conditions(regarding to extraneous materials) of fruit pulps sold in the Great São Paulo, during the four seasons of 2010. This investigation analyzed 115 tomato pulp, 93 guava pulp, 99 strawberry pulp and 89 mango pulp by means of the techniques described in the AOAC, 18th, 2005, Chapter 16 - Extraneous Materials: Isolation. Insect fragments were the most frequent filth category detected in the pulps (in 93 % of guava and strawberry, 77 % of tomato and 48 % of mango samples), followed by the rodent hair (in 24 % of tomato, in 3 % of guava, in 1 % of strawberry and in 0.5 % of mango samples). The occurrence of miteswas mostly frequent in strawberry samples (33 %). This study indicated that the majority of the analyzed pulps showed satisfactory sanitary conditions, evidencing that the Good Manufacturing Practices was adopted by the productive sector...
