Abstract: nt cell arteritis: A rare cause of posterior vasculitis Original Research (5048) Total Article Views Authors: Marilita M Moschos, Yan Guex-Crosier Published Date December 2008 Volume 2009:3 Pages 111 - 115 DOI: http://dx.doi.org/10.2147/OPTH.S4643 Marilita M Moschos1, Yan Guex-Crosier2 1Department of Ophthalmology, University of Athens, Greece; 2Jules Gonin Eye Hospital, University of Lausanne, Switzerland Purpose: To report three cases of posterior vasculitis associated with subacute giant cell arteritis (GCA). Methods: Three patients with decreased vision underwent complete ophthalmologic examination and fluorescein angiography. Results: All patients presented posterior vasculitis. Patient 1 had an erythrocyte sedimentation rate (ESR) of 38 mm/hr and a C-reactive protein (CRP) of 28mg/L. Patient 2 and 3 had an ESR of 104 and 95 mm/hr and a CRP of 42 and 195 mg/L accordingly. Diagnosis was established by temporal artery biopsy. Resolution was observed after systemic prednisolone therapy. Conclusion: GCA should be suspected when posterior vasculitis and relatively high ESR and CRP are present.

Clinical Ophthalmology , 2008,
Abstract: Marilita M Moschos1, Yan Guex-Crosier21Department of Ophthalmology, University of Athens, Athens, Greece; 2Jules Gonin Eye Hospital, University of Lausanne, Lausanne, SwitzerlandPurpose: To report a case with anterior and posterior nodules associated with systemic sarcoidosis.Methods: A patient with decreased vision underwent complete ophthalmologic examination, ultrasound biomicroscopy, fluorescein and indocyanine green (ICG) angiography.Results: The patient presented a nodule of the iris of the OS and of the optic nerves of both eyes. Chest computed tomography and tissue biopsy established the diagnosis.Conclusions: Fluorescein and ICG angiography are the only objective exams to demonstrate the extent of ocular involvement in a patient with sarcoidosis.Keywords: sarcoidosis, fluorescein angiography, indocyanine angiography

Abstract: clinical study of annular cyclitis Original Research (4510) Total Article Views Authors: Marilita Michael Moschos, Yan Guex-Crosier, Ioannis Margetis, Leonidas Zografos Published Date February 2009 Volume 2009:3 Pages 215 - 217 DOI: http://dx.doi.org/10.2147/OPTH.S4915 Marilita Michael Moschos1, Yan Guex-Crosier2, Ioannis Margetis1, Leonidas Zografos2 1Department of Ophthalmology, University of Athens, Greece; 2Jules Gonin Eye Hospital, University of Lausanne, Switzerland Purpose: To investigate six cases of annular cyclitis. Methods: All patients with impairment of visual acuity underwent complete ophthalmologic examination, color fundus photography, laboratory tests and fluorescein angiography. Indocyanine green (ICG) angiography and B-scan ultrasonography were also performed in three cases in order to diagnose the disease. Results: All patients presented a unilateral or bilateral granulomatous uveitis, associated with inflammatory annular cyclitis. They had a shallow anterior chamber, a mildly elevated intraocular pressure (under 25 mm Hg) and an annular serous retinal detachment. A resolution was observed after specific therapy associated with systemic prednisolone therapy and antiglaucomatous drops. Conclusion: This is the first description of an observational study of six patients with inflammatory annular cyclitis.

Abstract: case report: a 30-year-old man was referred to our ocular oncology service with a diagnosis of amelanotic choroidal melanoma of the left eye. the following tests were performed: ophthalmoscopy, fluorescein angiography, indocyanine green angiography, ultrasonography, magnetic resonance imaging and biopsy. discussion: the diagnosis of giant nodular posterior scleritis, as suggested by ultrasonography, was confirmed by biopsy. a comprehensive medical evaluation was performed, but no etiology was found. the histology revealed a granuloma compatible with ocular sarcoidosis. a rapid response was obtained by systemic steroid administration (1 mg/kg). sarcoidosis continues to be a challenge in diagnosis. it is important to distinguish nodular posterior scleritis from choroidal melanoma.

Abstract: Caso clínico: Un paciente de 30 a os fue enviado a nuestro servicio oncológico de referencia con el diagnóstico de melanoma amelanótico de la coroides del ojo izquierdo. Se hicieron los siguientes exámenes: oftalmoscopía, angiografía fluoresceínica, angiografía con verde de indocianina, ecografía, resonancia magnética y biopsia. Discusión: El diagnóstico de escleritis nodular posterior gigante basado en la ecografía se confirmó mediante una biopsia. Se realizó un examen médico completo buscándose el posible agente causal; no se encontró la etiología. La histología reveló un granuloma que era compatible con una sarcoidosis ocular. Mediante la administración de esteroides por vía oral (1 mg/kg), se obtuvo una evolución rápidamente favorable del cuadro. El diagnóstico de esta afección sigue siendo un desafío. Es importante diferenciar una escleritis posterior nodular de un melanoma de la coroides.

The validity of the SF-36 in an Australian National Household Survey: demonstrating the applicability of the Household Income and Labour Dynamics in Australia (HILDA) Survey to examination of health inequalities

BMC Public Health , 2004, DOI: 10.1186/1471-2458-4-44
Abstract: Data from 13,055 respondents who completed the first wave of the HILDA Survey were analysed to determine the psychometric properties of the SF-36 and the relationship of the SF-36 scales to other measures of health, disability, social functioning and demographic characteristics.Results of principle components analysis were similar to previous Australian and international reports. Survey scales demonstrated convergent and divergent validity, and different markers of social status demonstrated unique patterns of outcomes across the scales.Results demonstrated the validity of the SF-36 data collected during the first wave of the HILDA Survey and support its use in research examining health inequalities and population health characteristics in Australia.While much health research focuses on objective outcome measures such as mortality or morbidity defined through clinical assessment, there is an increasing emphasis on self-reported measures of health status and health-related quality of life. Self-reported measures of health status have been included in epidemiological and community-based survey research. Their use reflects the importance of considering the patients' point of view and the multidimensional nature of health [1-3].The Medical Outcomes Study Short Form (SF-36) is one of the most widely used, self-completion measures of health status. It was developed to meet the psychometric standards necessary for group comparisons, to enable profiling of functional health and well-being, and to quantify disease burden [3]. It comprises 36 items of which all but one are used to measure eight important health concepts that are frequently examined through health surveys. These eight concepts or scales are: Physical Functioning; Role-Physical (interference with work or other daily activities due to physical health); Bodily Pain; General Health; Vitality; Social Functioning (interference with normal social activities); Role-Emotional (interference with work or other daily acti
