Proptose causada por adenoma pituitário gigante: relato de caso
Pereira, Andréa;Monteiro, Mário Luiz Ribeiro;
Arquivos Brasileiros de Oftalmologia , 2003, DOI: 10.1590/S0004-27492003000400017
Abstract: purpose: to describe the unusual occurrence of unilateral proptosis associated with oculomotor palsy and blindness, caused by a giant pituitary adenoma. methods: the patient was submitted to clinical and ophthalmologic examination, visual field, magnetic resonance imaging and histopathological study after surgical intervention for the removal of the tumor. results: a 21-years-old woman had progressive bilateral visual loss, associated with proptosis and limitation of ocular motility of the left eye. visual field examination revealed a complete temporal hemianopsia in the right eye and no light perception in the left eye. magnetic resonance imaging showed a large tumor infiltrating the iii ventricule, cavernous sinus and orbital apex. the histopathological study revealed a pituitary adenoma producing prolactin and growth hormone without signs of malignancy. conclusions: this case is of interest not only because it documents the extremely rare occurrence of orbital involvement by a pituitary tumor but also because it emphasizes the need of an early diagnosis of invasive adenomas since such tumors not necessarily follow a benign clinical course despite their histologically benign nature.

Abstract: OBJETIVO: Relatar um caso raro de proptose unilateral associada à paralisia oculomotora e cegueira causados por adenoma pituitário gigante. MéTODOS: A paciente foi submetida a exame clínico e oftalmológico completo, campimetria, exame de imagem por ressonancia magnética e estudo histopatológico do tumor após interven o cirúrgica. RESULTADOS: Paciente de 21 anos apresentou perda visual progressiva bilateral associada à proptose e limita o da motilidade ocular do olho esquerdo. A campimetria revelou hemianopsia temporal completa no olho direito e havia ausência de percep o luminosa no olho esquerdo. O exame de imagem por ressonancia magnética mostrou extenso tumor infiltrando o terceiro ventrículo, seio cavernoso e ápice da órbita à esquerda. O estudo histopatológico revelou se tratar de adenoma hipofisário produtor de horm nio de crescimento e prolactina sem sinais de malignidade. CONCLUS O: Este caso é de interesse n o apenas pelo fato do envolvimento orbitário pelos adenomas ser extremamente raro, mas também para salientar a importancia de diagnóstico precoce uma vez que apesar da histologia benigna, os adenomas invasivos nem sempre seguem curso clínico favorável.

Abstract: ferric chloride as a new activating agent was used to obtain activated carbons from agroindustrial waste. this material was prepared at three temperatures of pyrolysis, 200, 280 and 400 oc. the carbonaceous materials obtained after the activation processes showed high specific surface areas (bet), with values higher than 900 m2 g-1. the materials showed different behaviors in the adsorption of methylene blue dye and reactive red textile dye in water solutions. an important fact in the use of fecl3 as an activating agent is that the activation temperature is at 280 oc, well below of those commonly employed in chemical or physical activations described in the literature.

Abstract: The environment has been a nation’s concern because of the consequences of human activities on life and environmental quality. The United Nations – UN, as an international congregation, has promoted various discussions and involvements of countries to adopt accountability measures towards the environment. Brazil, by the legal point of view, has moved positively into the implementation of mechanisms that promote environmental policies. Examples of this concern are highlighted in protectionist measures in the 1988 Constitution, the various councils and environmental systems, and more recently the Law nr. 12.305/10, setting important aspects in the management of Urban Solid Waste. This law attempts to prevent the waste production, and improve people and environmental safety. Thus, this qualitative study, with a descriptive-exploratory approach, refers to reverse logistics of health services waste from the public hospitals in Minas Gerais, the role and responsibilities of public and private management. In conclusion, the public hospitals of Minas Gerais state should change their management to achieve all the law 12,305/10 requirements.
