BACKGROUND Estimation of analgesia in anaesthetized children is often imprecise, and consequently, anaesthesiologists commonly evaluate children's response to surgical stimulation by movement or haemodynamic changes. In adults reflex pupillary dilatation has been demonstrated to be a very sensitive measure of noxious stimulation, correlated with opioid concentrations. The autonomic nervous cont...

Background: Estimation of time interval since death is an important aspect forensic medicine, it used as evidence in both civil and criminal cases. There are multiple techniques worldwide but reaction pupil to chemical agents currently the topic interest. Studies on role pilocarpine estimating post-mortem (PMI) very limited so current study aimed estimate using eye drops. Methods: An experiment...

A 38-year-old woman presented with acute right hemiplegia and aphasia and initial National Institutes of Health Stroke Scale Score of 18. The patient had past history of Arnold Chiari type I malformation, Attention Deficit Hyperactivity Disorder, fibromyalgia, migraines, and scoliosis. Due to clinical diffusion mismatch on MRI patient underwent an emergent cerebral angiogram which demonstrated ...

OBJECTIVES To evaluate the efficacy of digital pupillometry in the diagnosis of anisocoria related to Horner syndrome in adult patients. DESIGN Retrospective, observational, case control study. METHODS Nineteen patients with unilateral Horner syndrome (Horner group) and age-matched controls of 30 healthy individuals with normal vision and neither optic nerve dysfunction nor pupillary abnorm...

While bulk palladium is non-magnetic, several recent studies have shown that magnetism can occur in hcp Pd films, fcc twinned Pd nanoparticles, and Pd atomic strands. These studies show that small changes in Pd atomic configurations can induce magnetic properties. This raises the question of whether nanoscale Pd structures in general are magnetic. In this work, we examine coaxial palladium nano...

INTRODUCTION A patient affected by asymmetric hemodynamics of cerebro-afferent vessels underwent duplex color scanner investigations in occlusal proprioceptive un- and rebalance conditions. Pupillometric video-oculographic examinations were performed in order to spot connected trigeminal proprioceptive motor patterns able to interfere on sympathetic autonomic activity. The aim of this case repo...

Ocular parameters are influenced by sleep derivation and the use of chemical substances which are two major causes for traffic accidents. We assessed the use of these parameters as an objective screening tool for a driver’s fitness for duty. Pupillary diameter, pupil reaction to light and saccadic velocity were measured in 29 army truck drivers every morning for two months and compared to basel...

We evaluated the hypothesis that individual differences in working memory capacity are explained by variation in mental effort, persons with low capacity exerting less effort than persons with high capacity. Groups previously rated high and low in working memory capacity performed the reading span task under three levels of incentive. The effort hypothesis holds that low span subjects exert les...

The study described in this article was designed to evaluate visual fatigue induced during video display terminal (VDT) tasks. Newly developed equipment was used that can simultaneously measure pupillary change, focal accommodation, and eye movement. The changes in these 3 physiological measures, taken during a VDT task, were used to propose an index for evaluating visual fatigue. Through multi...
