The Effect of Outdoor Aeroallergens on Asthma Hospitalizations in Children in North-Western Tuscany, Italy.

2022

Few data are currently available on the effects of aeroallergens in triggering respiratory symptoms in children. To evaluate the potential effects of daily outdoor aeroallergens loads on childhood admissions, in this case-crossover study, we analyzed data from 85 children hospitalized at the University Hospital of Pisa, Italy, for asthma or asthma-like symptoms without respiratory infection, between 2010 and 2019. Data were linked to outdoor allergens, temperature, nitrogen dioxide, and relative humidity observed during the same period. A 10-grains/m3 increase in the total aeroallergen concentration was associated with an increased risk of admission at lag 0 (OR = 1.054, 95% CI: 1.011&ndash…

Preoperative pain neuroscience education combined with knee joint mobilization for knee osteoarthritis : a randomized controlled trial

2017

Abstract: Objectives: This study aimed to first compare the effects of a preoperative treatment combining pain neuroscience education (PNE) with knee joint mobilization versus biomedical education with knee joint mobilization on central sensitization (CS) in patients with knee osteoarthritis, both before and after surgery. Second, we wanted to compare the effects of both interventions on knee pain, disability, and psychosocial variables. Materials and Methods: Forty-four patients with knee osteoarthritis were allocated to receive 4 sessions of either PNE combined with knee joint mobilization or biomedical education with knee joint mobilization before surgery. All participants completed self…

Asthma phenotypes identified by latent class analysis in the ISAAC phase II Spain study.

2012

SummaryBackground Classification of respiratory symptoms may help to identify different underlying asthma phenotypes reflecting differences in aetiology and prognosis of wheezing disease among children. Objective To determine childhood asthma phenotypes based on respiratory symptoms from a widely used questionnaire to further classify phenotypes in international settings. Methods Between 2000 and 2002 cross-sectional studies were performed in four centres in Spain. Parental questionnaires were used to collect information on allergic diseases in more than 4000 children aged 8–12 years. In addition, objective markers for allergic sensitization and bronchial hyperresponsiveness (BHR) were meas…

The impact of age on prevalence of positive skin prick tests and specific IgE tests

2011

SummaryAging is associated with modifications of the immune system, defined as immunosenescence. This could contribute to a reduced prevalence of allergic disease in the elderly population. In this regard, atopy has rarely been considered in the clinical assessment of the geriatric respiratory patient. This article is a review of the available literature assessing the impact of age on atopy. In the majority of papers, we found a lower prevalence of atopy in the most advanced ages, both in healthy subjects and in individuals affected by allergic respiratory diseases. Unfortunately, no large, longitudinal studies performed in the general population have been conducted to further explore this …

Rhinitis as a risk factor for depressive mood in pre-adolescents: a new approach to this relationship

2014

Background Respiratory allergic symptoms impact on social life and school activities, influencing the patient's mood states. We evaluated the relationships between allergic respiratory diseases and depressive/anxious mood in a large sample of Italian middle school students, using the partial directed acyclic graph (P-DAG). Methods We studied 1283 subjects aged 10–13. A health respiratory questionnaire including questions relevant to socioeconomic status (HCI) and a test for depression and anxiety were administered. All subjects performed spirometry and skin prick tests. Results A causal role of rhinitis on depression was found: the likelihood of being depressed increased from 11.2 to 17.7%,…

Binge ethanol drinking during adolescence modifies cocaine responses in mice

2016

Binge ethanol drinking is an emerging pattern of excessive consumption among adolescents and young adults. Repeated ethanol intoxication has negative consequences during critical periods of brain development. Therefore, binge ethanol intake represents a vulnerability factor that promotes subsequent manifestations of neuropsychiatric disorders. In this study, we investigated the effects of oral binge ethanol intake during adolescence on the subsequent effects of cocaine in C57BL/6 mice. Firstly, we evaluated the oral ethanol intake of two binge ethanol procedures with different ethanol concentrations (20% v/v versus 30%, v/v). The highest ethanol intake was found in mice exposed to the lowe…

Expanded Distribution of Pain as a Sign of Central Sensitization in Individuals With Symptomatic Knee Osteoarthritis.

2016

AbstractBackgroundExpanded distribution of pain is considered a sign of central sensitization (CS). The relationship between recording of symptoms and CS in people with knee osteoarthritis (OA) has been poorly investigated.ObjectiveThe aim of this study was to examine whether the area of pain assessed using pain drawings relates to CS and clinical symptoms in people with knee OA.DesignThis was a cross-sectional study.MethodsFifty-three people with knee OA scheduled to undergo primary total knee arthroplasty were studied. All participants completed pain drawings using a novel digital device, completed self-administration questionnaires, and were assessed by quantitative sensory testing. Pain…

Corrigendum: Wired for motherhood: induction of maternal care but not maternal aggression in virgin female CD1 mice

2015

Virgin adult female mice display nearly spontaneous maternal care towards foster pups after a short period of sensitization. This indicates that maternal care is triggered by sensory stimulation provided by the pups and that its onset is largely independent on the physiological events related to gestation, parturition and lactation. Conversely, the factors influencing maternal aggression are poorly understood. In this study, we sought to characterize two models of maternal sensitization in the outbred CD1 strain. To do so, a group of virgin females (godmothers) were exposed to continuous cohabitation with a lactating dam and their pups from the moment of parturition, whereas a second group …

Association of Blattella germanica sensitization with atopic diseases in pediatric allergic patients

2011

Association of Blattella germanica sensitization with atopic diseases in pediatric allergic patients. Pediatr Allergy Immunol 2011; 22: 521–527. Abstract Background:  The extent to which the sensitization to the German cockroach Blattella germanica (BG) affects onset/presence of rhinoconjunctivitis (RC) in children is unknown. Objectives:  The present work was aimed to assess the prevalence of BG sensitization in an outpatient pediatric population from an allergy clinic, the association with allergic diseases, and the effect of age in children with allergic sensitization. Methods:  Five hu…
