Molecular, clinical and neuropsychological study in 31 patients with Kabuki syndrome and KMT2D mutations
2017
IF 3.326; International audience; Kabuki syndrome (KS-OMIM 147920) is a rare developmental disease characterized by the association of multiple congenital anomalies and intellectual disability. This study aimed to investigate intellectual performance in children with KS and link the performance to several clinical features and molecular data. We recruited 31 children with KMT2D mutations who were 6 to 16 years old. They all completed the Weschler Intelligence Scale for Children, fourth edition. We calculated all indexes: the Full Scale Intellectual Quotient (FSIQ), Verbal Comprehension Index (VCI), Perceptive Reasoning Index (PRI), Processing Speed Index (PSI), and Working Memory Index (WMI…
Prevalence of Age-Related Macular Degeneration in Europe
2017
Manuscript no. 2016-1147 Supplemental material is available at www.aaojournal.org/; International audience; [u]Purpose:[/u] Age-related macular degeneration (AMD) is a frequent, complex disorder in elderly of European ancestry. Risk profiles and treatment options have changed considerably over the years, which may have affected disease prevalence and outcome. We determined the prevalence of early and late AMD in Europe from 1990 to 2013 using the European Eye Epidemiology (E3) consortium, and made projections for the future. [u]Design:[/u] Meta-analysis of prevalence data. [u]Participants:[/u] A total of 42 080 individuals 40 years of age and older participating in 14 population-based cohor…
In the shadow of threatening norms: How students with visual impairment contest and reproduce institutional positions
2020
This article focuses on semi-narrative guided interviews with students with visual impairment (VI) who attend a state-approved special school for students with VI at the time of the interview, although they had different previous experiences in both segregated and inclusive schools. We are conducting a qualitative analysis from the perspective of teenagers concerning how they negotiate institutional ascriptions of (dis)abilities. We have selected interview sequences of two young people: (a) Kai: self-confidence and internalized self-doubt and (b) Felix: between fighting and claiming ableist divides. Our analyses reveal the different ways of how Kai and Felix each contest the ableist divide…

Optic nerve decompression in trauma and tumor patients
1999
Optic nerve decompression is a procedure that is now receiving increasing clinical attention. However, there are currently no standardized treatment protocols in the therapy of traumatic or pressure insults to the nerve. The present retrospective study was designed to report our experience with microscopic endonasal transethmoid-sphenoid optic nerve decompression in 24 unilateral trauma cases and 11 unilateral skull base tumor patients. In general preoperative visual acuities in the trauma patients were worse than in the tumor patients. Following surgery, 9 of 11 tumor patients (82%) had at least some improvement of their vision, including 5 complete recoveries. In the group with traumatic …
The association between diabetes and cataract among 42,469 community-dwelling adults in six low- and middle-income countries
2018
Background: Cataract is a major cause of visual impairment in people with diabetes, yet a paucity of data is available in low- and middle-income countries (LMICs) on this comorbidity. Thus we assessed the association between diabetes and cataract in 6 LMICs. Methods: Cross-sectional, community-based data from the Study on Global Ageing and Adult Health (SAGE) was analyzed (n = 42,469 aged ≥18 years). Five years information on self-reported diagnosis of cataract was collected. Three definitions for cataract were used: (a) Self-reported diagnosis and/or past 12-month symptoms; (b) Solely self-reported diagnosis; and (c) Surgical treatment for cataract in the past five years. Diabetes was base…
Prevalence and causes of blindness and low vision in the Casteldaccia Eye Study.
1994
In a population-based survey performed on the middle-aged and elderly population of Casteldaccia, Sicily, we found that the prevalence of blindness was 0.47% and the prevalence of low vision 1.22%. Unilateral blindness affected 2.81% of the population and unilateral low vision 4.12%. Visual impairment was much more frequently seen in subjects aged 70 years or more than in younger persons. The main cause of visual impairment was cataract, followed by amblyopia, which was responsible for many cases of unilateral low vision.
Poor vision accompanied with other sensory impairments as a predictor of falls in older women
2008
Objectives:we studied visual acuity (VA) and co-existing hearing impairment and poor standing balance as predictors of falls. Design: prospective study with 1-year follow-up. Setting: research laboratory and residential environment. Participants: 428 women aged 63‐76 years from the Finnish Twin Study on Aging. Measurements: participants were followed up for incidence of falls over 1 year. VA, hearing ability and standing balance were assessed at the baseline. The incidence rate ratios (IRR) for falls were computed using the negative binomial regression model. Results: during the follow-up, 47% of participants experienced a fall. After adjusting for age and interdependence of twin sisters, p…
Understanding of tactile pictures in visual impaired children
2015
The present PhD aims at understanding how Visual Impaired (VI) children process the tactile pictures that illustrate the tactile books specially designed for them. Our work is organized around two main axes of analysis. The first axis concentrates on the child who explores the tactile images, while the second axis focuses on the impact that the properties of these images can have on children’s haptic processing. Our researches included children presenting various degrees of visual impairment but without any associated disorders (in particular, without any cognitive delay), distinguishing early blind children from children with low vision. We also compared their performance with those of sig…
Organized Sport Participation and Physical Activity Levels among Adolescents with Functional Limitations
2017
Sufficient and regular physical activity is considered a protective factor, reducing the onset of secondary disability conditions in adolescents with chronic diseases and functional limitations. The aim of this study was to explore whether participation in organized sport may be associated to higher levels of physical activity in adolescents with functional limitations, based on a national representative sample. Data from the Health Behaviour in School-aged Children (HBSC) study collected in Finland from two data collection rounds (2002 and 2010) were conducted and pooled from adolescents aged between 13 and 15 years old with functional limitations (n = 1041). Differences in self-reported p…
