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 …
Cognitive impairment in multiple sclerosis can be predicted by imaging early in the disease.
2008
Background: Cognitive impairment is common in multiple sclerosis (MS) and adds significantly to the burden of the disease. The ability to predict future cognitive impairment from imaging obtained at disease onset has not been investigated. Methods: 62 patients imaged within 3 months of a clinically isolated syndrome were assessed neuropsychologically 7 years later. Baseline and periodic MRI measures of lesions, atrophy and normal-appearing white and grey matter were regressed against neuropsychological scores to explore the best predictors of cognitive outcome. Results: 28 patients had developed clinically definite MS at follow-up and a further nine met revised McDonald criteria for MS. Def…
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.
WAIS-IV Performance in Patients With Schizophrenia.
2019
Wechsler Adult Intelligence Scale (WAIS) is one of the most widely used instruments to measure cognitive functioning. The aims of this study were 1) to obtain the cognitive profile of Spanish patients with schizophrenia on the WAIS-IV; 2) to compare their profile to the profile of a healthy control group; and 3) to compare the cognitive profile of patients with schizophrenia to the performance observed in two separate previous studies in Canada and China. A sample of 99 outpatients and 99 healthy control participants, matched on age, sex, and educational level, were measured using the WAIS-IV, including 10 core subtests, 4 indices, and 2 general intelligence scores, to obtain their cognitiv…
Subcutaneous interferon β-1a may protect against cognitive impairment in patients with relapsing-remitting multiple sclerosis: 5-year follow-up of th…
2013
ObjectiveTo assess the effects of subcutaneous (sc) interferon (IFN) -1a on cognition over 5 years in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS).MethodsPatients aged 18-50 years with RRMS (Expanded Disability Status Scale score ≤4.0) who had completed the 3-year COGIMUS study underwent standardized magnetic resonance imaging, neurological examination, and neuropsychological testing at years 4 and 5. Predictors of cognitive impairment at year 5 were identified using multivariate analysis.ResultsOf 331 patients who completed the 3-year COGIMUS study, 265 participated in the 2-year extension study, 201 of whom (75.8%; sc IFN β-1a three times weekly: 44 µg, n = …
Cognitive impairment in Behçet's disease patients without overt neurological involvement
2003
We investigated the prevalence of cognitive impairment in patients with Behc¸et’s disease (BD) without overt neurological involvement. The influence of disease duration, disease activity, prednisone dosage, and anxiety and depression levels was evaluated. Twenty-six consecutive BD outpatients and 26 healthy controls matched for age, education and sex completed a comprehensive neuropsychological battery including tests of memory, visuospatial and constructional abilities, language, attention and psychomotor speed, non-verbal reasoning and executive functioning. The Hamilton scales for anxiety and depression were administered. Disease activity was assessed using the Behc¸et’s Disease Current …
Functional impairment in bipolar II disorder: Is it as disabling as bipolar I?
2010
It is well established that patients with bipolar disorder experience functional impairment even in remission. Nevertheless, bipolar II disorder remains understudied because most investigations to date include only bipolar I patients or just a small sample of bipolar II patients, without explicitly comparing both subtypes of disorder. The main objective of the current report is to evaluate overall and multiple domains of functioning, specifically in bipolar II disorder compared to patients with bipolar I disorder and healthy subjects.233 subjects from 3 groups were compared: bipolar I patients (n=106), bipolar II patients (n=66) and healthy controls (n=61). Bipolar patients meeting criteria…

Teoría de la mente y funcionalidad en pacientes bipolares en remisión sintomática
2013
Introducción: Los déficits en la funcionalidad son comunes durante la remisión en el trastorno bipolar (TB). Adicionalmente, existe evidencia de alteraciones en la cognición social en remisión clínica. Estos déficits podrían contribuir a la disfunción observada en estos pacientes. Material y métodos: Doce pacientes bipolares en remisión sintomática (7 bipolares tipo i y 5 de tipo ii) y 12 individuos controles sin patología psiquiátrica completaron el Test de las Miradas y el Test de Faux Pas para evaluar teoría de la mente (ToM), y el Test Breve para la Evaluación de la Funcionalidad (FAST). Resultados: El desempeño de los pacientes bipolares en el aspecto cognitivo de la ToM se ubicó por d…
