Recurrent upper respiratory tract infections in early childhood: a newly defined clinical condition.

BACKGROUND: Recurrent Upper Respiratory Tract Infections (R-URTIs) pose a significant challenge in pediatric healthcare, affecting both children and their families. This study aimed to investigate the prevalence, risk factors, and clinical implications of R-URTI in children aged 0-5 years. METHODS: This observational study involved a sample of 483 children aged 0-5 years, focusing on establishing a practical and dynamic definition of R-URTI. Family pediatricians prospectively collected socio-demographic information, medical history, and recorded the occurrence of URTI episodes. Children were followed from recruitment until March 2021, predating the COVID-19 outbreak. RESULTS: A substantial prevalence of R-URTIs was found, estimating it at 5-10% among this age group. To define R-URTI, a practical and dynamic criterion was proposed: children experiencing a minimum of four URTI episodes, each lasting four days or more, within a six-month period, with intervals of well-being in between. CONCLUSIONS: The study highlighted that specific risk factors for R-URTI were elusive, suggesting that this condition may affect children regardless of their family or clinical history. Moreover, the study's stratification by age group and times of observation facilitated patient-specific clinical decision-making. The proposed definition may represent a valuable tool for clinicians in diagnosing and addressing R-URTI cases.

Weaning, food allergens and potential risk factors for delayed introduction: a cross-sectional study.

Much evidence supports that the early introduction of allergenic foods in weaning is useful to prevent food allergies later in life. Real life is often different, with factors related to mothers and infants. Our study aimed to deepen the timing of introducing the foods responsible for most allergic reactions during the weaning and why parents delay their introduction. 110 mothers participated in the study, compiling a questionnaire. Exclusive breastfeeding was associated with a delayed introduction of allergenic foods at 4 months (r = 0.433, p < 0.01) and 1 year (r = 0.486, p < 0.01). Large-for-gestational age at birth was inversely associated with a delayed introduction of allergenic foods (r=-0.204, p < 0.05). This study demonstrates that introducing many allergens is delayed during the weaning. Parents with infants fed with exclusive breastfeeding could need more information about the correct time of introduction of potential allergens in the weaning.

The need of an updated culture of "occupational" atopic hand dermatitis in children at the time of COVID-19.

During the COVID-19 outbreak, handwashing emerged as an essential tool to prevent the spread of SARS-CoV-2 virus. It can put into practice using warm water and soap or, if not available, alcohol-based hand sanitizers (ABHS). Anyway, the use of warm water and soap is not always possible. On the contrary, ABHS are frequently used for their versatility, but can represent a risk factor for atopic dermatitis exacerbations in the pediatric age. At the same time, the Italian Ministry of Health established a school regulation, asking the students to periodically disinfect hands with sanitizing gel, or soap and water, especially before entering classrooms and laboratories, immediately after contact with everyday objects, after using the toilet, after throwing away the handkerchief and before and after eating. No rules have been personalized in this statement for children affected by atopic dermatitis attending the school. Based on this observation, we reported two case reports, involving children with a known diagnosis of atopic dermatitis, who attended our Pediatric Allergy Unit in Mantua, Italy. They experienced a worsening of symptoms related to AD on their hands in the last year for an intensive handwashing with ABHS before entering all classrooms and laboratories every day at school. Avoiding ABHS at school and washing their hands with a non-alcohol and additives soap and water solved their problem and brought their atopic dermatitis back to good control. So, it seems appropriate to consider ABHS as a "school trigger" and the low-controlled atopic dermatitis of these two patients as an "occupational dermatitis". An adequate pediatric culture of atopic dermatitis at the time of COVID 19 is needed.
