Managerial Behavior in the Lab: Information Disclosure, Decision Process and Leadership Style
2019
This paper reports the results from a lab experiment in which subjects playing the manager role can implement either an efficient / inegalitarian allocation or an inefficient / egalitarian allocation of payoffs. The experiment simulates a stylized managerial context by allowing the manager to manipulate information and select the decision process and by allowing the stakeholders to retaliate against the manager given different choices in the decision process. We found that the inefficient allocation is often selected and that this choice depends on whether the employees can retaliate against the manager and on whether the manager can hide information about the payoffs. The social preference…
Focus on paediatric and adolescent varicocoele: a single institution experience
2012
Summary The aim of this study was to report our long-term diagnostic and surgical outcome during the last 18 years, in paediatric and adolescent management of varicocoele. The present retrospective study enrols 374 patients observed at our institution between 1994 and 2011. Patients were divided into three groups: Group A includes 142 youngsters and adolescents treated with open surgery for left varicocoele, in which a pre-operative CDUS was not performed; Group B includes 65 patients treated with open surgery in which a pre-operative CDUS evaluation was carried out, to assess varicocoele haemodynamic pattern and testicular volume. Group C includes 167 patients treated by laparoscopy and wi…
The Effect of Perspective-Taking on Linguistic Intergroup Bias
2019
In this experiment, we examined the effect of perspective-taking—actively contemplating others’ psychological experiences—on linguistic intergroup bias. We asked some participants to adopt the perspective of a character (an Italian or a Maghrebian), while others did not receive similar instructions, and complete a short dialogue comprised of a series of vignettes, resulting in a 2 (perspective-taking: presence vs. control) × 2 (group: ingroup vs. outgroup) between-participants design. We analyzed the texts produced on the basis of the linguistic category model. As expected, participants were more likely to describe the outgroup member using less abstract terms when we asked them to take th…
Low-grade fever: how to distinguish organic from non-organic forms.
2010
Summary Background and aim: Low-grade fever (LGF) is defined as a body temperature between 37.5 and 38.3 °C, which is below the classical value reported for fever of unknown origin (FUO). We attempted to characterise its epidemiology, aetiology and clinical aspects to improve the methodological approach to diagnosis. Design and Methods: We reviewed and evaluated a survey of patients with LGF, followed as outpatients of our Department, a tertiary referral centre from 1997 to 2008. The same classifications were applied for classical FUO, and in the patients diagnosed with LGF, we also investigated for habitual hyperthermia (HH). Results: Seventy-three patients were selected and divided int…
Difensil immuno reduces recurrence and severity of tonsillitis in children: A randomized controlled trial
2020
Oral supplements (OS) support the immune system in fighting upper airways infection. This study aimed to analyze the effect of Difensil Immuno (DI) on the recurrence of tonsillitis and fever in children. A multicentric randomized clinical trial was conducted. One-hundred and twenty children with chronic tonsillitis were randomly assigned to group A, B or control. Patients in group A were treated with 10 mL of DI for 90 consecutive days, patients in group B underwent treatment with 15 mL of DI for 45 consecutive days. The following data were collected at baseline (T0), T1 and T2: tonsillitis and fever episodes, tonsillar volume, blood test results. One-way ANOVA was used to analyze within an…
Randomised double-blind clinical trial of intermediate- versus high-dose chloral hydrate for neuroimaging of children.
1995
Orally administered chloral hydrate is the most widely used sedative in children undergoing MRI. We compared intermediate- and high-dose oral chloral hydrate in 97 consecutive children undergoing MRI in a prospective, controlled, double-blind, randomised clinical trial. There were 50 girls and 47 boys, mean weight (+/- SD) 14.7 +/- 6.4 kg, and mean age 38 +/- 31. The children were randomly allocated to receive chloral hydrate syrup either 70 mg/kg (group A, n = 50) or 100 mg/kg (group B, n = 47). These two groups were not significantly different in sex, weight, age, diagnosis or ambulatory medication. The mean initial dose (+/- SEM) was 64 +/- 2 mg/kg for group A and 93 +/- 2 mg/kg for grou…
The Size of Subconjunctival Preparation Does Not Influence the Outcome of Trabeculectomy With Mitomycin C
2014
PURPOSE To compare the outcome of fornix-based trabeculectomy with mitomycin C (MMC) using 2 different sizes of subconjunctival preparation (36 mm² compared with 72 mm²). METHODS Prospective, randomized interventional case series. STUDY POPULATION Patients 18 to 85 years of age with open-angle glaucoma and progressive visual field defects under maximum tolerated medical therapy were randomized to undergo initial fornix-based trabeculectomy with MMC (0.2 mg/mL for 5 min) with subconjunctival preparation of 6×6 mm (group A) or 8×9 mm (group B). Main outcome parameters were: intraocular pressure (IOP), best-corrected visual acuity (BCVA), number of 5-fluorouracil (5-FU) injections, and laser s…
Influence of operative strategy for the aortic arch in DeBakey type I aortic dissection: Analysis of the German Registry for Acute Aortic Dissection …
2012
Objective Patients treated with an extensive approach including total aortic arch replacement for acute aortic dissection type A may have a favorable long-term prognosis by treating the residual false lumen. Our goal was to analyze the operative strategy for treatment of type I DeBakey aortic dissection from the German Registry for Acute Aortic Dissection Type A (GERAADA) data. Methods A total of 658 patients with type I DeBakey aortic dissection and entry only in the ascending aorta were identified in the GERAADA. Patients in group A underwent replacement of the ascending aorta with hemiarch replacement. Patients in group B received extensive treatment with total arch replacement or conven…
Epidemiology of Toxoplasma and CMV serology and of GBS colonization in pregnancy and neonatal outcome in a Sicilian population
2013
Background: Aim of our study is to analyze the immunological status in pregnancy for two main TORCH agents, Toxoplasma and Cytomegalovirus (CMV), and the results of group B streptococcus (GBS) screening, assessing the risk for congenital infection in a population from Palermo, Italy. Methods: We retrospectively analyzed the medical records of all inborn live newborns who were born in our division during 2012, gathering information about the mother, the pregnancy and neonatal hospitalization at birth. Whenever data were available, we categorized the serologic status of the mothers for Toxoplasma and CMV. We also considered the results of rectal and vaginal swabs for GBS. We compared the resu…
Combination of alpha lipoic acid and gabapentin, its efficacy in the treatment of burning mouth syndrome : a randomized, double-blind, placebo contro…
2010
Burning Mouth Syndrome (BMS) is a disease that manifests as burning in the tongue or in any area of the oral mucosa, in the absence of clinically verifiable injuries. Objectives: To verify the efficacy of alpha lipoic acid (ALA) and gabapentin (GABA), used individually and jointly, to reduce the burning in patients with burning mouth and establish a drug therapy for the BMS. Study Design: During April and May 2008, we conducted a randomized, double-blind, placebo-controlled trial in the Department of Clinical Stomatology, Faculty of Dentistry, Rosario, Argentina. The gathering of patients was between those ones with BMS who were treated in our service between March 2003 and March 2008 witho…
