Addition of a nutraceutical to montelukast or inhaled steroid in the treatment of wheezing during COVID-19 pandemic: a multicenter, open-label, randomized controlled trial.

Background and aim Recurrent wheezing is often triggered by viral respiratory infections. The aims of our study were: i) to evaluate whether the addition of a nutraceutical (Leucodif®), could improve the efficacy of montelukast or inhaled steroids (ICS) compared to the single treatment; ii) to verify whether a treatment is more effective than another. Our study was biased by the COVID-19 pandemic, which resulted in a lockdown of almost two months in Italy.

IL-17 serum level in patients with chronic mucocutaneous candidiasis disease.

Background: Chronic mucocutaneous candidiasis (CMC) is defined by recurrent or persistent superficial infections involving nails, skin, and/or oral and genital mucosae. IL-17 promotes the recruitment, chemotaxis, and expansion of neutrophils and acts directly on keratinocytes and epithelial cells, driving the production of antimicrobial peptides, essential for the immune response against Candida.

Aim: To evaluate the serum level of IL-17 in a family affected by CMC restricted to the nails of the hands and feet.

Cetirizine modifies quality of life and symptoms in children with seasonal allergic rhinitis: a pilot study.

Background and aim Seasonal allergic rhinitis (SAR) is a common disease in childhood that is characterized by bothersome symptoms and impaired quality of life (QoL). As histamine is the pivotal pathogenic mediator in SAR, antihistamines are the first-line option in the treatment. Cetirizine is a well-known effective antihistamine.

Covid-19 and cardiac involvement in childhood: state of the art.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first described in a cluster of patients in Wuhan, China, in December of 2019. Over the past few months, COVID-19 has rapidly spread worldwide becoming the first pandemic of the 21st century. COVID-19 results in mild symptoms in most infected children but can cause acute cardiac injury and death.

Cardiac malformations in children with congenital hypothyroidism.

Congenital hypothyroidism (CH) is the most common endocrine disease in children, according to literature, infants with CH have an increased risk of associated congenital malformations (CM), especially cardiac defects (CD), compared to the general population. We retrospectively analyzed medical records of 255 patients with a positive screening result for CH in the period 1991-2016 followed at our Center. At the time of enrollment, the clinical examination included looking for the presence of heart murmurs and dysmorphic features.

Cardiovascular risk factors in childhood obesity.

Childhood obesity is the "disease of the century". This article reviews the early cardiovascular risk factors and the recommendations to prevent them in the overweight and obese children. A comprehensive search of published literature was carried out to identify all articles published on this topic in English and Italian from 1999 to 2020.

Hypertension in childhood.

Hypertension is a growing health problem in children, and it is an important parameter of cardiovascular risk for adults. It is classified as primary (influenced by obesity, sedentary lifestyles and poor-quality food) or secondary to underlying causes. The AAP 2017 guidelines recommend measuring blood pressure every year from the age of three and in children under the age of three only if they have known risk factors.

Respiratory syncytial virus seropositivity at birth is associated with adverse neonatal respiratory outcomes.

Background: More than 60 years since the discovery of the respiratory syncytial virus (RSV), the effects of prenatal exposure to this virus remain largely unknown. In this investigation, we sought to find evidence of RSV seroconversion in cord blood and explore its clinical implications for the newborn.

Methods: Offspring from 22 pregnant women with a history of viral respiratory infection during the third trimester of pregnancy (respiratory viral illness [RVI] group) and 40 controls were enrolled in this study between 1 September 2016 and 31 March 2019.

Antihistamines in children and adolescents: A practical update.

Histamine is a chemical mediator, released predominantly by tissue mast cells, circulating basophils, and neurons, which are activated in response to various immunological and non-immunological stimuli. Histamine has to bind to specific receptors to exert its physiological and pathophysiological functions. Endogenous histamine is the main mediator of the immediate allergic response, which moreover, performs other multiple functions, including regulation of gastric secretion, neurotransmission in the central nervous system, and immunomodulatory activity.

Bacteriotherapy with Streptococcus salivarius 24SMB and Streptococcus oralis 89a nasal spray for treatment of upper respiratory tract infections in children: a pilot study on short-term efficacy.

Background: Recurrent respiratory infections (RRIs) are defined by the presence of at least one of the following criteria: (i) > 6 annual respiratory infections (RIs); (ii) > 1 monthly RIs involving the upper airways from September to April; (iii) > 3 annual RIs involving the lower airways represent a very common health problem in the first years of life. We conducted a multi-centre, prospective, single-open study to assess the efficacy and the safety of Streptococcus salivarius 24SMBc and Streptococcus oralis 89a in the prevention of upper respiratory tract infections (URTIs) in children.

Methods: Ninety-one children (M:F = 47:44, mean age 7.

Cetirizine use in childhood: an update of a friendly 30-year drug.

Cetirizine is a second-generation antihistamine, derived from the metabolism of hydroxyzine, highly specific for the H1 receptors, and with marked antiallergic properties. Although its history began more than 30 years ago, it remains one of the most used drugs in children with a leading role in the medical care of children with allergic diseases. Cetirizine use is licensed for paediatric patients for the treatment of allergic rhinitis, and chronic spontaneous urticaria, in Europe in children older than 2 years old and in the USA in children older than 6 months old.

Antihistamines: ABC for the pediatricians.

Antihistamines are currently one of the most commonly administered drugs in children. They are used to treat symptoms that depend on histamine release, namely allergic diseases, such as rhinitis, asthma, urticaria, and anaphylaxis. It is possible to distinguish first- and second-generation antihistamines.

Recurrent respiratory infections between immunity and atopy.

Recurrent respiratory infections (RRIs) are frequent in children and are characterized by more than 6 airway infections in 1 year or more than 1 upper airway infection per month in the period between September and April or more than 3 lower airway infections in 1 year. Often pediatric RRIs are related to predisposing factors, such as reduced airway size, poor tussive reflex, and immaturity of the immune system. RRIs due to immature immune system are a transient condition, with spontaneous resolution in the school age.

Focus on the cetirizine use in clinical practice: a reappraisal 30 years later.

Antihistamines are currently one of the most commonly administered categories of drugs. They are used to treat symptoms that are secondary to histamine release, which is typical of certain allergic conditions, including rhinitis, conjunctivitis, asthma, urticaria, and anaphylaxis. Cetirizine belongs to the second-generation family, so, it is very selective for peripheral H1 receptors, is potent and quickly relieves symptoms, exerts additional anti-allergic/anti-inflammatory effects, and is usually well-tolerated.

Local therapy with ozone in the management of the exit site in a patient undergoing peritoneal dialysis.

The natural history of children with end stage renal disease is dialysis until a transplant can be done. There are two types of dialysis: hemodialysis and peritoneal dialysis (1). Peritoneal dialysis is preferred in young children because getting the vascular access for hemodialysis is challenging (2).

Cardiac dysfunction in children with essential obesity: preliminary data.

Obesity in children has been recognized as a major underlying factor of the pathogenesis of several diseases and a reduced life expectancy. This study aims to verify if clinical parameters, such as waist circumference and/or body mass index and biohumoral and inflammatory parameters can help predict cardiac structural and functional alterations, through an echocardiogram test in obese children and adolescents. Children were prospectively enrolled at the AUOC outpatients' department of Emergency Paediatrics, University Hospital, Messina, from June to December 2017.

Renal anomalies in newborns with vacterel association: case series and literature review.

Nocturnal enuresis (NE) was defined by the World Health Organization (ICD-10) and the American Psychiatric Association (DSM-5) as bed-wetting in children aged >5 years. In cases of mental retardation, the developmental age may be equivalent to 5 years. In this review, we focus on the current knowledge about the etiology of enuresis and the most recent therapeutical options.

Nephrotic syndrome: immunological mechanisms.

Nephrotic Syndrome (NS) is a rare diseases (around 2-7 cases per 100.000 children per year) characterized by proteinuria ≥50 mg/kg/day (or ≥40 mg/m2/h) or a proteinuria/creatininuria ratio >2 (mg/mg); hypoalbuminaemia less than 25 g/l and edema. The protein leakage, with the consequent hypoalbunaemia and edema, due to podocyte alterations may be caused by genetic diseases, immunological mechanisms, infections, toxins or malignancy.

Failure to thrive: the importance of measuring the electrolytes.

Diabetes insipidus (DI) is characterized by hypoosmotic polyuria related to deficiency of arginine-vasopressin (AVP) secretion (centraldiabetesinsipidus, CDI) or renalinsensitivity to AVP (nephrogenicdiabetesinsipidus, NDI). We report a case of a child with congenital NDI.

Novel therapeutic targets for allergic airway disease in children.

The aim of precision medicine is setting up targeted therapies for selected patients that would ideally have high effectiveness and few side effects. This is made possible by targeted therapy drugs that selectively act on a specific pathway. Precision medicine is spreading to many medical specialties, and there is increasing interest in the context of allergic airway diseases, such as allergic rhinitis, chronic rhinosinusitis, and asthma.
