Manifestation of speech and language disorders in children with hearing impairment compared with children with specific language disorders.
2010
Children with hearing impairment (HI) often suffer from speech and language disorders. We wondered if the manifestation of these disorders resembled the ones in children with specific language impairment (SLI). Using matched pairs, we compared the manifestation of a speech and language disorder in 5- and 6-year-old children with HI and SLI. We looked at receptive language skills using the Reynell scales, the lexicon, syntax and morphology, output phonology, and phonological short-term memory. Receptive language skills were more impaired in HI children. No significant differences were recorded for all other domains. We conclude that language deficits that are at least partially caused by the…
Can loss of sensory attenuation be accurately demonstrated using two effectors simultaneously?
2015
Sir, Recently, Parees and colleagues (2014) compared patients with functional (psychogenic) movement disorders and healthy subjects who were asked to match a force delivered to their left finger by pressing on it directly, or by operating a joystick to press down on it, with the other hand. They observed that healthy subjects generated more force than required when pressing directly on their finger (compared with using the joystick), whereas patients did not. They interpreted and discussed this result as a loss of sensory attenuation that typically occurs in healthy subjects during self-generated movements and suggested by return, that it illustrates an altered sense of agency for the patie…
Cochlear implant complications and failures
2010
Abstract Introduction Cochlear implantation is a relatively safe surgery performed on profound bilateral hearing loss patients. Its surgical indications have increased and the age of implantation has decreased over the last years. As with any other surgery, it presents complications; device failure is one of the most important, given its potential risk for the need to explant and reimplant the device. Objective To evaluate cochlear implant complications, determine possible causes and discuss medical and surgical management. Material and methods A retrospective study of cochlear implants was performed. A total of 246 implants over an eleven-year period were evaluated. The sample consisted of…
Comparative Study Between Unilateral and Bilateral Cochlear Implantation in Children of 1 and 2 Years of Age
2016
Abstract Introduction The studies that have evaluated the effectiveness of bilateral cochlear implantation in children suggest an improvement in hearing about sound localisation and speech discrimination. In this paper we show the differences in audio-linguistic achievements with early bilateral cochlear implantation versus unilateral, and differences between simultaneous and sequential bilateral implantation. Material and methods We present 88 children with bilateral profound sensorineural hearing loss, treated with bilateral cochlear implantation in 32 cases and unilateral in 56 cases, during the first 12 months (27 children) of life and between 12 and 24 months (61 children). We conducte…
The combination of diffractive and refractive multifocal intraocular lenses to provide full visual function after cataract surgery.
2009
PURPOSE To investigate if implantation of a far dominant refractive multifocal intraocular lens (IOL) in one eye and a near dominant diffractive multifocal IOL in the fellow eye improves range of vision following cataract surgery. METHODS This was a prospective, nonrandomized, case-control study involving 20 patients (40 eyes) scheduled for cataract surgery. Inclusion criteria were bilateral cataracts, minimum age 50 years, availability for follow-up visits, and informed consent. All patients received a far dominant refractive multifocal IOL (ReZoom, Abbott Medical Optics) in their dominant eye and a near dominant diffractive multifocal IOL (Tecnis ZM900, AMO) in their nondominant eye. Preo…
Visual outcomes and complications of congenital cataract surgery
2019
Corresponding author at: Department of Ophthalmology, 14, rue Paul-Gaffarel, 21000 Dijon, France. This work is issued from the oral presentation during the 123rd congress of the French Ophthalmological Society.; International audience; PURPOSE: To describe the visual results and postoperative complications of congenital cataract surgeries performed between 2005 and 2016. METHODS: A retrospective consecutive case series of congenital cataract surgeries was carried out at the Dijon University Hospital in France. Intraocular lens implantation was primary or secondary according to age. Pre- and post-operative assessment was performed through ophthalmologic consultations with orthoptic measureme…
Evolution of otosclerosis to cochlear implantation.
2011
Abstract Introduction Otosclerosis is an osteodystrophy of the labyrinthine capsule producing conductive hearing loss. If the process invades the cochlea, a sensorineural hearing loss usually takes place. The cochlear implant is a good alternative in these patients. Objective To ascertain the behaviour of cochlear implantation (CI) in otosclerosis. Material and methods We reviewed a database of 250 patients who underwent CI, performing a retrospective study of 13 patients with clinical, audiological and/or imaging findings of bilateral otosclerosis. The 26 ears were studied as to their natural history, previous surgeries, evolution to profound hearing loss, computed tomography (CT) images, …
Change in kidney volume after kidney transplantation in patients with autosomal polycystic kidney disease
2018
BackgroundThe indication to bilateral nephrectomy in patients with autosomal dominant polycystic kidney scheduled for kidney transplantation is controversial. Indeed, the progressive enlargement of cysts may increase the risk of complications and the need for nephrectomy. However, very few studies investigated the change in kidney volume after kidney transplantation.Material and methodsIn this prospective cohort study, the change in native kidney volume in polycystic patients was evaluated with magnetic resonance imaging. Forty patients were included in the study. Kidney diameters and total kidney volume were evaluated with magnetic resonance imaging in patients who underwent simultaneous n…
Intensità degli scambi agroalimentari tra i Paesi del bacino del Mediterraneo
2013
The Mediterranean has always been an area of strategic interest for the European Union (eu), which, since its establishment, has woven a compact network of relationships with its trading partners in the South and East of the Mediterranean, signing cooperation and then associative agreements with them. This study aims to present a view of how the agro-food trade network has evolved between the eu’s Mediterranean partner countries and their neighbors in North Africa and the Near East. To measure the extent of this trade specific indicators are used which are also widely used in economic literature, albeit to analyze trade in sectors unconnected to agro-food. In particular, analyses carried ou…
An ACE Wholesale Electricity Market Framework with Bilateral Trading
2011
In this paper, an agent-based simulation model for a hybrid power market structure is presented. A bilateral transaction mechanism is combined with a uniform-pricing auction settlement in order to isolate the impact of medium-term bilateral contracts on market power and spot prices in a competitive wholesale market setting. First we describe the negotiation method for bilateral trading of energy and then introduce a new approach for bidding in the DA market based on the load duration curve. We find that, despite the conventional concerns, the foreclosure effect produced by the bilateral agreement between a generation and a retail business will not necessarily lead to higher prices, and will…
