COMPARATIVE EVALUATION of OCULOMETRIC VARIABLES IN GRAVES' OPHTHALMOPATHY

OBJECTIVES: To estimate oculometric parameters of Graves' ophthalmopathy in comparison to healthy eyes using digital photography and digital image analysis.INTRODUCTION: Graves' ophthalmopathy is the main cause of eye proptosis. Because these protrusions cause clinically perceived distortions in orbital architecture, digital photographs can be used to detect and quantify these changes.METHODS: We carried out a cross-sectional study comprising 12 healthy volunteers and 15 Graves' ophthalmopathy patients with the purpose of evaluating the use of simple, non-invasive digital photography to estimate oculometric parameters of Graves' ophthalmopathy and compare them with the parameters of unaffected eyes. Facial photographs of cases and controls were taken in a standardized manner. Oculometric parameters were compared between the groups and then correlated to proptometer measures.RESULTS: All estimated oculometric variables showed significant differences between the groups, in particular with regard to mediopupilar aperture, lateral height, distance from the iris edge to the lateral boundary of the palpebral fissure, and distance from the higher point of the iris to the lateral limit of the palpebral fissure. The product of medial aperture and horizontal palpebral fissure also revealed greater discrepancy between the groups. Proptometer measures showed significant linear correlation between the distance from the iris edge to the lateral boundary of the palpebral fissure and between the distance from the higher point of the iris to the lateral limit of palpebral fissure (p<0.05).CONCLUSIONS: Comparative analysis of oculometric parameters in Graves' ophthalmopathy suggests that eye proptosis is related to an asymmetric increase in lateral oculometric measures. Standardized digital photographs can be used in clinical practice to objectively estimate oculometric parameters of Graves' ophthalmopathy patients.

Avaliação da silagem de milho das variedades granífera e forrageira no desempenho de bovinos das raças nelore e cachim em regime de confinamento

The experiment was carried out to evaluate corn grain and corn forage varieties productivity and nutritive value for silage comparing to the performance of Nellore and Canchim cattle in a feedlot. A completely randomized design was used with a 2 x 2 factorial arrangement based on two breeds (Nellore and Canchim) and two corn varieties (grain and forage). Harvest was made after 120 days sowing, when plants showed more than 2/3 of dry. leaves and grains were in dough stage. The silage was stored in a 400 tons. The experimental diet consisted of grain and forage corn silage, 7,2 liters of liquid yeast (1,5 kg of dry yeast/ head/day) and 1,1 kg of ground corn (1,0 kg of dry matter/head/day). The experiment duration was 110 days, with a 20 days adaptation period and 90 days for data collection. Animals were regularly weighted every 28 days. It was concluded that corn grain was more appropriate for silage than corn forage, and in the same stage it showed a higher dry matter content and a 41.3% higher grain yield, promoting higher weight gain and better feed/gain ratio in the feedlot beef cattle.

Thermoanalytical study of nimesulide and their recrystallization products obtained from solutions of several alcohols

Thermogravimetry, differential scanning calorimetry, and vibrational infrared spectroscopy were used to study nimesulide and its recrystallization products that were obtained from solutions of several alcohols. The thermoanalytical measurements were performed in both air and nitrogen atmospheres and the results suggest that, under the experimental conditions used in this paper, it was possible to obtain neither polymorphic nor pseudopolymorphic forms of this drug. In this investigation, quantum chemical approach methods were used to determine the molecular structures using the Becke three-parameter hybrid method and the Lee-Yang-Parr correlation functional. The performed molecular calculations were done with the Gaussian 09 routine and the theoretical calculation results were correlated with the experimental IR vibrational spectrum. © 2013 Akadémiai Kiadó, Budapest, Hungary.

O jogo como mediador na entrevista: um novo lugar no processo psicoterápico com adolescentes

It is a fact that between the child and the adult there is an adolescent being that experiments his experiences in a different way than those others. Therefore, in clinical care, the use of toys and play do not have the same value as for the children, and, on the other hand, the majority of adolescents are not ready, as the adult is, for the exclusive use of speech in the psychotherapy context. There is the need to introduce some specific strategy in order to give the adolescent conditions to express himself openly in the psychotherapy process. The mediator's resource introduces this variable to enable the expression of emotions for those who cannot find the available channels for that. This paper seeks to answer this question by presenting the Time Tunnel Game in the psychotherapy with young people, based, during several years, on its clinical use with patients during this period of their lives. Explaining, when it is a question of a demand for a game, that the youngster tries to respect the rules, therefore, expressing his experiences more at ease. By using the mentioned game, it is not the psychotherapist that questions or addresses the youngster, but it is through this playing that the questions arise, providing the youngster a facilitating context for his experiences, even for the more difficult ones. At the direct request of the psychotherapist, it is possible that the adolescent may have the imposing idea that he is being evaluated, which is inadequate when attending any youngster. It is understood that this facilitation also occurs because in a game the atmosphere of lucidity is less threatening to the patient to reveal himself as playing. It is the game that "interviews" and, therefore, the youngster has less to be afraid of when expressing his experiences.
