Abstract: introduction: malignant intraocular tumors are associated with an increase in the aqueous flare, caused by alterations of the blood-ocular barriers through various mechanisms. several studies have demonstrated an ocular flare increase using flare photometry in eyes with benign and malignant tumors. purpose: to evaluate flare photometry as an adjunct method in the differential diagnosis of choroidal malignant melanoma and choroidal nevus comparing to normal control eyes. methods: eyes with melanoma and nevus were diagnosed by indirect binocular ophthalmoscopy and/or ultrasound were evaluated. the fellow normal eyes were used as a control. in all subject and control eyes flare photometry was performed using the laser flare meter (fc 500, kowa), under mydriasis. statistical analysis was done using the wilcoxon, mann-whitney, and spearman tests. results: thirty-one eyes with malignant melanoma and 18 eyes with nevus were evaluated. the flare photometry average in the eyes with malignant melanoma was 17.1 ph/ms and in the control fellow eyes it was 4.06 ph/ms. in eyes with choroidal nevus the flare photometry average was 6.12 ph/ms and in the control fellow eyes it was 4.47 ph/ms. the flare photometry was higher in eyes with malignant melanoma and nevus than in the fellow normal eyes (p<0.001 and p<0.01). comparing the eyes with malignant melanoma and nevus, flare photometry was significantly higher in eyes with malignant melanoma (p<0.001). there was a positive correlation between the tumor thickness and flare photometry (r=0.47). conclusion: flare photometry is a helpful tool in the differential diagnosis of malignant melanoma and choroidal nevus.

Abstract: Introdu o: Os tumores malignos intra-oculares est o associados com um aumento do "flare" na camara anterior, causado por uma quebra na barreira hemato-aquosa, que pode ocorrer por vários mecanismos. Estudos utilizando a flarefotometria confirmam o aumento do "flare" em olhos com tumores intra-oculares malignos e benignos. Objetivo: Avaliar a flarefotometria como auxiliar no diagnóstico diferencial de melanoma maligno e nevo de coróide, comparando-se com olhos contralaterais normais. Métodos: Foram avaliados olhos com melanoma maligno e olhos com nevo de coróide diagnosticados por meio de oftalmoscopia indireta e/ou ultra-sonografia. Os olhos normais contralaterais foram utilizados como controles. A flarefotometria foi realizada em todos os pacientes, sob midríase bilateral, utilizando equipamento Laser Flare Meter (FC 500, Kowa). Foram aplicados os testes de Wilcoxon, Mann-Whitney, e Spearman para análise estatística. Resultados: A média da flarefotometria nos olhos com melanoma maligno de coróide foi 17,1 ph/ms e nos olhos normais contralaterais foi 4,06 ph/ms. Nos olhos com nevo de coróide o valor da flarefotometria foi 6,12 ph/ms e nos olhos contralaterais normais foi 4,47 ph/ms. O valor da flarefotometria foi maior nos olhos com melanoma maligno e nevo quando comparado com os olhos contralaterais normais (p<0,001 e p<0,01). Nos olhos com melanoma maligno o valor da flarefotometria foi significantemente maior que nos olhos com nevo de coróide (p<0,001). Foi observada correla o positiva entre a espessura do tumor e a flarefotometria (r=0,47). Conclus o: A flarefotometria é um exame útil no diagnóstico diferencial entre melanoma maligno e nevo de coróide.

Ballalai, Priscilla Luppi;Hirashima, Denise Emiko;Pólvora, Rafael Piuma;Rigueiro, Moacyr;Lowen, Márcia;
Arquivos Brasileiros de Oftalmologia , 2001, DOI: 10.1590/S0004-27492001000400016
Abstract: the authors present a case of a child with organoid nevus syndrome, characterized by epibulbar choristoma in the right eye, jadassohn's nevus sebaceous in the scalp and arachnoid cist. the pathology of the ocular lesion revealed a mixture of ectodermal and mesodermal elements, leding to the rare diagnosis of epibulbar complex choristoma.the syndrome is rarely described in the ophthalmologic literature. some considerations are made regarding ophthalmologic and systemic associations.

Abstract: OBJETIVO: Avaliar a seguran a, a eficácia e a recidiva tumoral após o uso de mitomicina C (MMC) tópica no tratamento de neoplasias intra-epiteliais (NIC) primárias e recidivadas e carcinomas espinocelulares (CEC) recidivados. MéTODOS: Dois grupos de pacientes foram tratados. Grupo 1 com diagnóstico de NIC primário ou recidivado fez uso do colírio de MMC 0,02%, 4 vezes ao dia por 28 dias. O grupo 2 com diagnóstico de CEC recidivado fez uso do colírio de MMC 0,02%, 4 vezes ao dia por 21 a 28 dias. Após o término do tratamento era feita citologia exfoliativa para controle ou biópsia nos casos de les o residual. RESULTADOS: Oito pacientes com NIC e 1 com CEC mostraram regress o total da les o e citologia exfoliativa de controle negativa para células neoplásicas. Em 1 paciente com NIC e 2 com CEC, houve regress o parcial das les es, tendo sido necessária exérese cirúrgica da les o residual, com exame anatomopatológico negativo para neoplasia. Os efeitos colaterais foram transitórios e desapareceram após a suspens o do colírio. N o houve recidiva tumoral num seguimento médio de 24,9 meses. CONCLUS O: Os resultados preliminares desse estudo su-gerem que o uso da MMC tópica é op o segura e eficaz como tratamento único de NIC primária ou recidivada e no tratamento do CEC recidivado, porém n o evitando a cirurgia na maioria dos pacientes com CEC. N o foram observadas recidivas tumorais durante o segmento. Mais estudos s o necessários, com maior número de pacientes e maior tempo de seguimento para confirmar esses resultados.

Abstract: purpose: this study was designed to evaluate the use of human amniotic membrane for ocular surface reconstruction after conjunctival squamous cell carcinoma resection. methods: amniotic membrane was obtained at the time of cesarean section and was preserved at -80oc in glycerol and cornea culture media at a ratio of 1:1. the inclusion criteria were patients presenting proliferating lesions suggestive of squamous cell carcinoma (flat or elevated white lesions resembling "fish meat") that involve the conjunctiva, limbus and cornea. eight eyes of 8 patients with conjunctival "squamous cell carcinoma" underwent tumor resection with amniotic membrane transplantation. three of these cases underwent total corneal epitheliectomy and amniotic membrane transplantation associated with limbal autograft. results: mean follow-up time was 17.8 months (range, 10-35 months). in four patients (71.4%) surgical treatment was successful, with good ocular surface stability. in two patients (28.6%) results were partially successful, with mild cicatricial alterations. one patient was excluded from the study due to aggressive tumor recurrence with intraocular invasion that needed to be removed with exenteration. conclusion: this study suggests that amniotic membrane transplantation is a good alternative for ocular surface reconstruction after conjunctival squamous cell carcinoma resection.
Comentario a propósito de la presentación de la Dra. Elza Berquó. Reflexiones teórico metodológicas sobre la elaboración de cuestionarios de encuesta: una experiencia de integración de enfoques
Luppi, Irene;
Revista Brasileira de Epidemiologia , 2008, DOI: 10.1590/S1415-790X2008000500009
Abstract: se presenta una reflexión teórico metodológica sobre la elaboración de cuestionarios de encuesta recuperando dos cuestiones claves se?aladas por la dra. berquó, en su testimonio sobre las iniciativas desarrolladas en el campo de la salud reproductiva con el objetivo de producir datos que se puedan utilizar para formular políticas e implementar intervenciones en los distintos contextos: la complejidad y la flexibilidad. en particular, cuando se abordan cuestiones de mayor dificultad para su objetivación, tales como los pareceres, las valoraciones de los sujetos en relación con sus prácticas y las experiencias de padecimiento y cuidado. se enfatiza la necesidad de un riguroso examen de las categorías analíticas susceptibles de ser tratadas empíricamente y de la funcionalidad de los conceptos para la producción de indicadores de contenidos sistematizables para la comparación estadística. se presenta una experiencia de aplicación de un cuestionario, como instancia de integración metodológica en una investigación por encuesta, destinada a lograr una aproximación directa al universo de representaciones y valoraciones de la mujer, no mediada por los códigos y la lógica de quien las indaga. para su confección se recuperaron los hallazgos de una investigación antropológica preliminar y se armó un dispositivo de preguntas con expresiones textuales de las entrevistadas, a la manera de un esquema de apoyo del discurso de la mujer. la propuesta presentada, de relativa simplicidad, puede contribuir a superar dificultades vinculadas con la viabilidad de captación de determinadas temáticas según los contextos socioculturales, a nivel internacional.

"La nada del yo que soy": Desestabilizacionesde la autobiografía en la teoría literaria hacia fines de los '70
Luppi,Juan Pablo;
Enfoques , 2010,
Abstract: this paper proposes a reading of some passages from barthes' autobiographical scheme in roland barthes by roland barthes (1975), according to notions present in paul de man's essay "autobiography as defacement" (1979). by relying on the figures of rhetoric, one of them; and by reformulating lacan's categories, the other; both reflections constitute theories of reading, which discuss at least two variables often present in the interventions of the theoretical field: the category of genre and the notion of subject.
última novela del escritor en sus comienzos: La grande y el proyecto de Saer
Luppi,Juan Pablo;
Anclajes , 2010,
Abstract: supporting the illusion that is possible to start again, la grande (2005) redefines juan josé saer ′s project back to zero. favored by occasion of death while writing, although prior to that contingency, this last novel eludes ending and gets back to beginnings to go on narrating: it advances going back. la grande recovers and crosses one another two characters that had been suspended in the beginning (en la zona) and towards the end of the project (lugar), and effects subtle changes of function over recognized and established narrative pattern, mainly through a false intrigue ′s explosion, which covers space expanded to the universe and reaches represented subjectivities.
