Pseudoneglect in schizophrenia: A line bisection study with cueing

2007

Numerous authors have reported the existence of lateralised abnormalities towards the right side in patients with schizophrenia.In the present study, a manual line bisection task was used to assess the existence of a visuospatial bias in patients with schizophrenia as compared to healthy subjects and left unilateral neglect patients. In addition, we used a local cueing paradigm (consisting of a number placed on the right, on the left, or at both ends of the line).Healthy subjects showed a leftwards trend in the "no cue" condition (known as pseudoneglect) and neglect patients showed a right bias in all cue conditions. In contrast, patients with schizophrenia placed their manual estimation of…

Knee arthroscopy and exercise versus exercise only for chronic patellofemoral pain syndrome: a randomized controlled trial.

2007

Abstract Background Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS). As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS. Methods A total of 56 patients with chronic PFPS were randomized into two treatment groups: an arthroscopy group (N = 28), treated with knee arthroscopy and an 8-week home exercise program, and a control group (N = 28), treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and fu…

Abstract Objective To compare the postoperative inflammation after phacoemulsification followed by intraocular lens (IOL) implantation by means of sclerocorneal versus clear corneal tunnel incision. Design Randomized controlled clinical trial. Participants One hundred eyes of 100 patients were examined at a German University eye hospital. Intervention One hundred eyes with cataract necessitating phacoemulsification with posterior chamber IOL implantation were randomly assigned to receive a temporal sclerocorneal or clear corneal tunnel incision by a single surgeon.

A new delivery system of clobetasol-17-propionate (lipid-loaded microspheres 0.025%) compared with a conventional formulation (lipophilic ointment in…

2004

Summary Background  Topical application of clobetasol-17-propionate has been diffusely reported as an efficacious therapy in atrophic/erosive oral lichen planus (OLP), without exposing the patient to systemic side-effects. However, prolonged contact and respective topical effects on the oral mucosa should be avoided. Objectives  The aim of the present study was to evaluate efficacy and compliance of new lipid microspheres loaded with 0·025% of clobetasol propionate (formulation A) compared with a commonly used formulation (a sort of dispersion of a lipophilic ointment in a hydrophilic phase) with the same amount of drug (formulation B) in the topical treatment of OLP. Patients and methods  …

Photodynamic therapy with verteporfin for juxtafoveal choroidal neovascularization in pathologic myopia: a long-term follow-up study.

2007

Purpose To assess the effect of verteporfin photodynamic therapy (PDT) in juxtafoveal choroidal neovascularization (CNV) secondary to pathologic myopia (PM). Design Prospective, open-label, consecutive, interventional case series. Methods We prospectively followed a series of 48 consecutive patients (49 eyes) with pathologic myopia (≥ 6 diopters) who received verteporfin PDT for juxtafoveal CNV. This population was divided into two groups based on age (group A ≤ 55 years old, group B >55 years old), in three subgroups based on CNV lesion size, and in three categories based on refractive error at baseline. Results The median follow-up was 32 months (range, 12 to 56 months). Visual acuity (VA…

Clinical outcomes after implantation of a posterior chamber collagen copolymer phakic intraocular lens with a central hole for myopic correction.

2013

Purpose To evaluate the efficacy, predictability, safety, and stability of a new-model posterior chamber Implantable Collamer Lens phakic intraocular lens (pIOL) (V4c Visian) to correct myopia. Setting Private practice, Oviedo, Spain. Design Case series. Methods This study enrolled patients who had implantation of a new pIOL design with a central hole for more natural aqueous flow, eliminating the need for neodymium:YAG iridotomy or peripheral iridectomy. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refractive error, intraocular pressure (IOP), endothelial cell count, central vault, and adverse events were evaluated 6 months postoperatively. Results The study enroll…

Association of low birth weight with myopic refractive error and lower visual acuity in adulthood: results from the population-based Gutenberg Health…

2017

PurposeLow birth weight (BW) is linked to impaired organ development in childhood, including altered ocular morphological and functional development. The aim of this study was to evaluate whether low BW has long-term effects on visual acuity and refraction in adulthood.MethodsThe Gutenberg Health Study is a population-based, observational cohort study in Germany, including 15 010 participants aged between 35 and 74 years. These participants were divided into three different BW groups (low: <2500 g; normal: between 2500 and 4000 g; and high: >4000 g). Best-corrected visual acuity and objective refraction were examined. We used multivariable linear regression models with adjustment for …

Prevalence of refractive errors in the European adult population: the Gutenberg Health Study (GHS).

2014

Objective To study the distribution of refractive errors among adults of European descent. Design Population-based eye study in Germany with15 010 participants aged 35–74 years. Methods The study participants underwent a detailed ophthalmic examination according to a standardised protocol. Refractive error was determined by an automatic refraction device (Humphrey HARK 599) without cycloplegia. Definitions for the analysis were myopia +0.5 D, astigmatism >0.5 cylinder D and anisometropia >1.0 D difference in the spherical equivalent between the eyes. Exclusion criterion was previous cataract or refractive surgery. Results 13 959 subjects were eligible. Refractive errors ranged from −21.5 to…

RhinAsthma patient perspective: a short daily asthma and rhinitis QoL assessment.

2012

Background The present study aimed to develop a short validated patient-completed questionnaire, the RhinAsthma Patient Perspective (RAPP), to assess the health-related quality of life (HRQoL) in patients with asthma and comorbid allergic rhinitis in clinical practice. Methods A provisional RAPP questionnaire was formed from candidate items identified through retrospective analysis of 333 RHINASTHMA questionnaires. This was then tested on 150 asthma patients with allergic rhinitis. Results Psychometric analyses identified eight items fitting a unidimensional model to form RAPP. Internal consistency (Cronbach's alpha coefficient > 0.8) and agreement with RHINASTHMA (r = −0.31, P = 0.0001) we…
