Considerable deficits in the detection performance of the cat after lesion of the suprasylvian visual cortex
1989
The ability of two cats to discriminate between two geometrical outline patterns in the presence of superimposed structured background was tested before and after bilateral removal of the lateral suprasylvian visual areas (PMLS, PLLS, AMLS, ALLS, part of area 7). There were mild deficits when patterns and background were kept stationary; these deficits may be due to a partial undercutting of areas 17, 18 and 19. However, there was a severe impairment in performance when the patterns were moving on a stationary background which may be due to loss of the suprasylvian visual areas. Movement of the background relative to the figure resulted in an intermediate detection deficit.
Prescription of anti-osteoporosis medications after hospitalization for hip fracture: a multicentre Italian survey.
2017
Purpose: Literature data indicate that the proportion of patients with recent hip fracture who receive a prescription for anti-osteoporotic drugs is low and does not seem to increase over time. This study aimed to obtain data on the prescription for anti-osteoporotic drugs in Italian patients discharged after a recent hip fracture and to assess which variables could have influenced the decision for prescribing osteoporosis medication. Methods: A total of four Italian centres located in four different geographical areas (Siena, Verona, Naples and Palermo) participated in this retrospective study. In each centre, experienced clinicians gathered the data of up to 200 consecutive patients disch…
A survey around the Italian pediatric units on current clinical practice for Sleep Disordered Breathing (SDB)
2019
Background During recent years, interest on Sleep Disordered Breathing (SDB) in pediatric age has increased, due to the impact on quality of life, psycho-physical attitude and other serious morbidities if undiagnosed and untreated. Methods Italian Pediatric Respiratory Diseases Society (SIMRI) SDB-Working Group carried out an exploratory survey in Italy, from January to December 2016, to assess the diagnostic and therapeutic pathways, perception and relevance of SDB in Italian Hospitals. Results A questionnaire was sent to 180 Pediatric Units (PUs) distributed throughout the Italy; 102 Pediatric Units (PUs; 56.6%) answered and among them 57% dealt with SDB, and 94% recognized SDB as a major…
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…
Identification of the Uric Acid Thresholds Predicting an Increased Total and Cardiovascular Mortality Over 20 Years
2020
Serum uric acid (SUA) levels discriminating across the different strata of cardiovascular risk is still unknown. By utilizing a large population-based database, we assessed the threshold of SUA that increases the risk of total mortality and cardiovascular mortality (CVM). The URRAH study (Uric Acid Right for Heart Health) is a multicentre retrospective, observational study, which collected data from several large population-based longitudinal studies in Italy and subjects recruited in the hypertension clinics of the Italian Society of Hypertension. Total mortality was defined as mortality for any cause, CVM as death due to fatal myocardial infarction, stroke, sudden cardiac death, or heart…
Prevalence of use and appropriateness of antidepressants prescription in acutely hospitalized elderly patients.
2019
Depression is often under-recognized in older patients, even if antidepressants (AD) are commonly prescribed, with a prevalence of use that increase with ageing [ 1 ]. Nevertheless, even if a diagnosis of depression is established, inappropriate treatment can occur [ 2 ]. Beers criteria are the most widely screening tools used to detect inappropriate prescription of drugs in people aged 65 years or more [ 3 ]. Since 2010, attempts to adapt the Beers' criteria have been made in Europe [ 4 , 5 ]. Tricyclic drugs are the ADs to be always avoided in the elderly, owing to their anticholinergic side effects, such as cognitive impairment, delirium, urinary retention and falls [ 3 ]. Selective sero…
Idiopathic infantile asymmetry, proposal of a measurement scale
2004
Abstract To evaluate the development of idiopathic infantile asymmetry and the efficacy of therapeutic interventions, spinal scoliosis can be quantified on the basis of radiographs. For obvious reasons, use of this technique is limited. Here we present a clinical method to describe and quantify infantile asymmetry. For item selection, spontaneous movements (SMs), reactive movements (RMs) and length differences were video recorded in 30 infants (median age 10 weeks, range 6–16) with variable degrees of asymmetry. Within these three categories, reactive movements elicited by head turns to the right and left side in the prone and supine position emerged as reliable parameters reflecting trunk …
Time processing in children with Tourette's syndrome.
2010
Background: Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is abnormal in TS. Methods: We compared time processing abilities between nine children with TS-only (i.e. without major psychiatric comorbidities) and 10 age-matched healthy children, employing a time reproduction task in which subjects actively reproduce different temporal intervals, and a time comparison task in which subjects judge whether a …
Clinical findings of Takotsubo cardiomyopathy: results from a multicenter international study
2008
BACKGROUND: Takotsubo cardiomyopathy consists of reversible systolic left ventricular apical ballooning associated with chest pain. Electrocardiographic abnormalities and the minimal rise of serum cardiac markers are similar to those in acute myocardial infarction, but without evidence of myocardial ischemia or injury. To date, many reports concerning this kind of acute reversible heart failure have been published, but the information available about the management of affected patients is scarce and the clinical data are incomplete. AIMS: In the present study, we report a collection of 40 patients who were affected by Takotsubo cardiomyopathy obtained in a multicentric international study, …
The Use of Neoadjuvant Chemotherapy in Patients With Urothelial Carcinoma of the Bladder: Current Practice Among Clinicians.
2017
Abstract Introduction Guidelines recommend neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) in patients with urothelial carcinoma of the bladder in clinical stages T2-T4a, cN0M0. We examined the frequency and current practice of NAC and sought to identify predictors for the use of NAC in a prospective contemporary cohort. Materials and Methods We analyzed prospective data from 679 patients in the PROMETRICS (PROspective MulticEnTer RadIcal Cystectomy Series 2011) database. All patients underwent RC in 2011. Uni- and multivariable regression analyses identified predictors of NAC application. Furthermore, a questionnaire was used to evaluate the practice patterns of NAC at the PR…
