1263: Symptoms and signs of posterior uveitis

ACTA OPHTHALMOLOGICA, Issue 2010
M KHAIRALLAH
Purpose Posterior uveitis (PU) is an important anatomic form of uveitis in which the primary site of inflammation is the choroid or retina, with or without subsequent vitreous involvement. Methods Review of symptoms and signs of PU. Results The onset of PU can be sudden or less frequently insidious. Most common ocular symptoms include blurred vision, loss of vision, and floaters. Some patients with PU may have no symptoms, especially if inflammatory process is asymmetric. PU is usually associated with vitritis that can vary from mild to severe. Vitritis should be graded according to standardized grading systems. Other vitreous changes may include vitreous strands, vitreous hemorrhage, vitreous traction, and posterior vitreous detachment. Retinal and/or choroidal inflammation can be focal, multifocal, or more diffuse. It is important to distinguish between active and inactive chorioretinal disease. Retinal vasculitis can occur in the setting of several PU entities. It can involve retinal veins or arteries. It appears as focal, multifocal, or diffuse vascular cuffing or sheathing. Other retinal vasculitic changes include retinal hemorrhages, retinal vascular occlusion, retinal/optic disc neovascularization, and aneurysms. Maculopathy is common patients with PU. It may result from direct inflammatory infiltration, macular edema, serous retinal detachment, retinal ischemia, epiretinal membrane, or macular hole. Optic nerve involvement that can occur in association with PU include optic disc hyperemia/edema, optic neuritis, neuroretinitis, optic disc exudate, and optic disc granuloma. Conclusion Clinical examination is a key step in the diagnostic approach to PU. Clinician should be aware of the array of ocular symptoms of signs and their importance in orienting the differential diagnosis. [source]

4151: Epidemiology of uveitis in the Middle East and North Africa

ACTA OPHTHALMOLOGICA, Issue 2010
M KHAIRALLAH
Purpose Numerous studies have examined the pattern of uveitis around the world. Most of them are from western countries, including the USA and countries in Europe, and Eastern Asia. The aim of this presentation is to review the epidemiological characteristics of uveitis in the the Middle East and North Africa. Methods The epidemiologic data on uveitis available from the Middle East and North Africa were reviewed. Results Several recent studies addressed the pattern of uveitis in different countries, including Iran, Saudi Arabia, Turkey, and Tunisia. Uveitis was most often seen in adults with a peak age at presentation in the third and fourth decades. There was no dramatic difference in gender distribution. Anterior uveitis was the most common anatomic form of uveitis, but a high rate of posterior uveitis and panuveitis was reported. A definitive or presumed specific diagnosis could be established for 57-87% of patients. The most common infectious entities were herpetic anterior uveitis, toxoplasmosis, and tuberculosis (Saudi Arabia). The most common identifiable non-infectious entities included Behçet's disease and Vogt-Koyanagi-Harada disease. Conclusion Herpetic infection, toxoplasmosis, and tuberculosis are the most common infectious causes of uveitis in the Middle East and North Africa. Behçet's diease and Vogt-Koyanagi-Harada disease are the most common non-infectious uveitic entities.HLA-B27 acute anterior uveitis, ocular sarcoidosis, and juvenile idiopathic arthritis associated uveitis are less common than in western countries.

A new index for rating aesthetics of implant-supported single crowns and adjacent soft tissues , the Implant Crown Aesthetic Index

CLINICAL ORAL IMPLANTS RESEARCH, Issue 6 2005
A pilot study on validation of a new index
Abstract Objectives: The important item of aesthetics is rarely included in evaluation studies. The aim of this study was to develop and validate an index for rating aesthetics of implant-supported single crowns and adjacent soft tissues. Material and methods: Nine items were selected, which have an influence on the aesthetic result. The items are based on the anatomic form, colour and surface characteristics of the crown and on the anatomic form, colour and surface characteristics of the peri-implant soft tissues. Two oral-maxillofacial surgeons and two prosthodontists rated 24 implant-supported single-tooth restorations and adjacent soft tissues on a form with the nine items of the rating index. The rating was carried out twice by each of the examiners. Weighted Cohen's , was calculated to express the intra- and interobserver agreement. Results: Intraobserver results indicated that the agreement between the first and second rating of both the prosthodontists was good (both 0.7) and that the agreement of the oral-maxillofacial surgeons was moderate (0.49 and 0.56). The best interobserver agreement was found between the two prosthodontists (0.61, good agreement). Conclusions: The Implant Crown Aesthetic Index is an objective tool in rating aesthetics of implant-supported single crowns and adjacent soft tissues. The rating is best be carried out by one prosthodontist to have the highest reliability. Résumé L'aspect important qu'est l'esthétique est rarement inclus dans les études d'évaluation. Le but de cette étude était de développer et de valider un index pour évaluer l'esthétique d'implants avec une couronne unique et les tissus mous adjacents. Neuf points ayant une influence sur le résultat esthétique ont été sélectionnés. Ces points sont basés sur une forme anatomique, des caractéristiques de surface et de couleur de la couronne et de la forme anatomique, la couleur et les caractéristiques de surface des tissus mous paroïmplantaires. Deux chirurgiens maxillo-faciaux et deux spécialistes en prothèse ont évalué 24 restaurations de dents uniques sur implants et leurs tissus mous adjacents dans un formulaire avec les neuf points de l'indice d'évaluation. L'évaluation a été effectuée deux fois par chacun des examinateurs. Le kappa de Cohen a été calculé pour exprimer l'accord intra- et inter-observateurs. Les résultats intra-observateurs ont indiqué que l'accord entre la première et la deuxième évaluation étaient bonnes pour les spécialistes en prothèse (les deux 0,70) et l'accord pour les chirurgiens était moyen (0,49 et 0,56). Le meilleur accord inter-observateurs était trouvé entre les deux spécialistes de prothèse (0,61, bon accord). L'indice d'esthétique de la couronne sur implant est un outil objectif dans l'évaluation de l'esthétique des couronnes uniques sur implant et les tissus mous adjacents. L'évaluation est mieux effectuée par un spécialiste en prothèse pour obtenir la plus haute précision. Zusammenfassung Ziele: Der wichtige Faktor Aesthetik wird kaum in Untersuchungen miteinbezogen. Das Ziel dieser Studie war, einen Index zur Wertung der Aesthetik von implantatgetragenen Einzelkronen und der angrenzenden Weichgewebe zu entwickeln und zu werten. Material und Methoden: Neun Punkte wurden ausgewählt, welche einen Einfluss auf das Ästhetische Resultat haben. Die Punkte basierten auf der anatomischen Form, Farb- und Oberflächencharakteristiken der Krone und auf der anatomischen Form, Farb- und Formcharakteristiken der peri-implantären Weichgewebe. Zwei Kieferchirurgen und zwei Prothetikspezialisten bewerteten 24 implantatgetragene Einzelkronen und die angrenzenden Weichgewebe auf einem Formular mit 9 Punkten des Wertungsindex. Die Bewertung wurde von jedem Untersucher zweimal durchgeführt. Es wurden gewichtete Cohen`s Kappa berechnet, um die Uebereinstimmung innerhalb der Untersucher und zwischen den verschiednen Untersuchern auszudrücken. Resutate: Die Resultate innerhalb der Untersucher zeigten, dass die Uebereinstimmung zwischen der ersten und der zweiten Bewertung bei beiden Prothetikern gut war (beide 0.7) und dass die Uebereinstimmung bei den Kieferchirurgen mässig ausfiel (0.49 und 0.56). Die beste Uebereinstimmung zwischen zwei verschiedenen Untersuchern wurde zwischen den beiden Prothetikern gefunden (0.61, gut Uebereinstimmung). Schlussfolgerung: Der Implantat Kronen Aesthetik Index stellt ein objektives Werkzeug zur Bewertung der Aesthetik von implantatgetragenen Einzelkronen und der angrenzenden Weichgewebe dar. Die Bewertung wird am besten durch einen Prothetikspezialisten durchgeführt, um die höchste Zuverlässigkeit zu erhalten. Resumen Objetivos: El punto importante de la estética raramente se incluye en estudios de evaluación. La intención del presente estudio fue desarrollar y validar un índice para valorar la estética de las coronas unitarias implantosoportadas y los tejidos blandos adyacentes. Material y métodos: Se seleccionaron nueve puntos, que tienen influencia en el resultado estético. Los puntos se basan en la forma anatómica, color y características de la superficie de la corona y en la forma anatómica, color y características de la superficie de los tejidos blandos periimplantarios. Dos cirujanos maxilofaciales y dos prostodoncistas valoraron 24 restauraciones unitarias implantosoportadas y los tejidos blandos adyacentes en un formulario con nueve puntos del índice de valoración. La valoración se llevó a cabo dos veces por cada examinador. Se calculó el weighted kappa de Cohen para expresar la concordancia intra- e interobservador. Resultados: Los resultados intraobservador indicaron que el acuerdo entre la primera y la segunda valoración de ambos prostodoncistas fue buena (ambos 0.70) y que el acuerdo de los cirujanos maxilofaciales fue moderada (0.49 y 0.56). El mejor acuerdo interobservador se encontró entre los dos prostodoncistas (0.61, buen acuerdo). Conclusión: El Índice de Estética de Coronas de Implantes es una herramienta objetiva en la valoración de la estética de las coronas unitarias implantosoportadas y los tejidos blandos adyacentes. La valoración se llevó mejor a cabo por un prostodoncista que tuvo la mayor fiabilidad. [source]

AUSTRALIAN DENTAL JOURNAL, Issue 2 2009
B Ayna
Abstract Background:, Polyethylene fibre-reinforced composites (FRCs) have been under development for some time. However, there is a lack of data on the clinical performance of these restorations. The purpose of this descriptive study was to evaluate the clinical performance of endodontically treated anterior teeth restored using polyethylene FRCs. Methods:, Eighty-seven endodontically treated anterior teeth in 65 patients were restored with polyethylene FRCs. The restorations were placed by three operators. The patients were recalled for examinations every year for up to three years. The restorations were evaluated using modified Ryge and USPHS criteria. Results:, A statistical analysis showed no significant difference in marginal irregularity, marginal discolouration, surface texture, wear/anatomic form, fracture and retention, radiographic appearance, or debonding between the baseline and three-year results. Conclusions:, Based on our three-year examination results, polyethylene FRC restorations appear to be clinically successful. [source]
