Purpose: There is some controversy whether or not saccades change with age. This cross-sectional study aims to clarify the characteristics of reflexive saccades at various ages to establish a normative cohort in a standardized set-up. Second objective is to investigate the feasibility of saccadometry in daily ophthalmological practice. Methods: One hundred healthy participants aged between 6 and 76 years underwent an ophthalmologic examination and saccadometry, using an infrared video-oculography device, sampling at 220 Hz. The reflexive saccades were evoked in four directions and three target displacements each (5°/15°/30° horizontally and of 5°/10°/20° vertically). Saccadic peak velocity,…

The impact of perioperative complications on favorable outcomes after artificial urinary sphincter implantation for post-prostatectomy incontinence

2020

ABSTRACT Objective To investigate the effect of perioperative complications involving artificial urinary sphincter (AUS) implantation on rates of explantation and continence as well as health-related quality of life (HRQOL). Materials and methods Inclusion criteria encompassed non-neurogenic, moderate-to-severe stress urinary incontinence (SUI) post radical prostatectomy and primary implantation of an AUS performed by a high-volume surgeon (>100 previous implantations). Reporting complications followed the validated Clavien-Dindo scale and Martin criteria. HRQOL was assessed by the validated IQOL score, continence by the validated ICIQ-SF score. Statistical analysis included Chi (2) test, M…

O046. Color vision and visual cortex excitability are impaired in episodic migraine. Simply coexisting or pathophysiologically related dysfunctions?

2015

Background and objectives Evidence of abnormal color vision processing in migraine comes from observation of positive symptoms during visual aura, effects of strong color contrast triggering attacks and of colored-spectacles reducing migraine frequency. Although the central or peripheral basis of such color misperception remains unclear, several authors reported a selective deficit of shortwavelength cones (S-cones) [1]. Sound-induced flash illusions (SIFI) are a simple way to describe visual distorsion induced by acoustic perception. SIFI critically depend on excitability of primary visual cortex (V1) as they are reduced by facilitatory anodal transcranial direct current stimulation (tDCS)…

O069. Menstrual cycle affects cortical excitability differently in females with migraine and in healthy controls: a new perspective by cross modal so…

2015

The sound-induced flash illusions (SIFI) represent a valid tool to explore multimodal perception and are critically dependent on visual and acoustic cortical excitability [1, 2]. In a previous study [3], we observed a significant reduction of illusions in migraine patients with respect to healthy controls, probably due to a condition of visual cortex hyperexcitability. Aim of the present study was to evaluate SIFI perceptions in healthy women and patients with menstrual migraine and to describe the effects of cyclical change of steroid hormones and cortical responsiveness.

Inclusión de la inyección percutánea de etanol como primera línea de tratamiento de los quistes tiroideos sintomáticos

2021

Abstract Background Our aim was to evaluate the efficacy and security of ultrasound-guided percutaneous ethanol injection therapy (US-PEIT) for the treatment of recurrent symptomatic thyroid cysts in two high-resolution consultations of thyroid nodule in the Valencian Community. Patients and methods The study comprised thirty-three consecutive patients (51 ± 12 years, 76% women) with symptomatic benign thyroid cysts relapsed after drainage and benign cytology prior to treatment. Through ultrasound, maximum cyst diameter and volume were determined, and the content of the cyst was drained. We then instilled between 2 and 4 ml of ethanol (according to initial volume). We followed up with ultra…

Effects of alfa-hydroxy-isocaproic acid on body composition, DOMS and performance in athletes

2010

Abstract Background Alfa-Hydroxy-isocaproic acid (HICA) is an end product of leucine metabolism in human tissues such as muscle and connective tissue. According to the clinical and experimental studies, HICA can be considered as an anti-catabolic substance. The present study investigated the effects of HICA supplementation on body composition, delayed onset of muscle soreness (DOMS) and physical performance of athletes during a training period. Methods Fifteen healthy male soccer players (age 22.1+/-3.9 yr) volunteered for the 4-week double-blind study during an intensive training period. The subjects in the group HICA (n = 8) received 583 mg of sodium salt of HICA (corresponding 500 mg of …

<p>Alteration in binocular fusion modifies audiovisual integration in children</p>

2019

Background: In the field of multisensory integration, vision is generally thought to dominate audiovisual interactions, at least in spatial tasks, but the role of binocular fusion in audiovisual integration has not yet been studied. Methods: Using the Maddox test, a classical ophthalmological test used to subjectively detect a latent unilateral eye deviation, we checked whether an alteration in binocular vision in young patients would be able to change audiovisual integration. The study was performed on a group of ten children (five males and five females aged 11.3±1.6 years) with normal binocular vision, and revealed a visual phenomenon consisting of stochastic disappearanceof part of a vi…
