The aim of this guidance is to provide recommendations to clinicians and other interested parties on chronic urticaria in children. The Italian Society for Pediatrics (SIP), the Italian Society for Allergy and Immunology (SIAIP), the Italian Society for Pediatric dermatology (SIDerP) convened a multidisciplinary panel that prepared clinical guidelines for diagnosis and management of chronic urticaria in childhood. Key questions on epidemiology, natural history, diagnosis, and management were developed. The literature was systematically searched and evaluated, recommendations were rated and algorithms for diagnosis and treatment were developed. The recommendations focus on identification of diseases and comorbidities, strategies to recognize triggering factors, improvement of treatment by individualized care.
The COVID-19 pandemic has surprised the entire population. The world has had to face an unprecedented pandemic. Only, Spanish flu had similar disastrous consequences. As a result, drastic measures (lockdown) have been adopted worldwide. Healthcare service has been overwhelmed by the extraordinary influx of patients, often requiring high intensity of care. Mortality has been associated with severe comorbidities, including chronic diseases. Patients with frailty were, therefore, the victim of the SARS-COV-2 infection. Allergy and asthma are the most prevalent chronic disorders in children and adolescents, so they need careful attention and, if necessary, an adaptation of their regular treatment plans. Fortunately, at present, young people are less suffering from COVID-19, both as incidence and severity. However, any age, including infancy, could be affected by the pandemic. Based on this background, the Italian Society of Pediatric Allergy and Immunology has felt it necessary to provide a Consensus Statement. This expert panel consensus document offers a rationale to help guide decision-making in the management of children and adolescents with allergic or immunologic diseases.
Objective: The loss of pancreatic beta-cells is thought to be one of the principal causes of diabetes mellitus (DM) in cystic fibrosis (CF), but the role of peripheral insulin resistance (IR) in the pathogenesis of DM in CF remains unclear. The aim of this study was to evaluate whether eventual changes of glucose tolerance (GT) over time were associated with modifications of insulin secretion or sensitivity. Methods: Plasma glucose and insulin responses to an oral GT test (OGTT) were investigated and reinvestigated 13 years later in 14 CF patients with initial and persistent fasting euglycemia and no history of insulin treatment. Insulin sensitivity (IS) at both tests was assessed on the basis of insulin and glucose levels both in the fasting state and during OGTTs. Results: From the 1st to the 2nd OGTT: (a) the prevalence of DM responses significantly increased; (b) the areas beneath the respective glucose and insulin curves significantly increased and decreased respectively; (c) IR and IS indices decreased and increased respectively, even in the patients who developed DM; (d) pulmonary function significantly worsened in the entire series, especially in the patients who developed DM. Conclusions: (i) the natural history of glyco-metabolic status in CF is characterized by deteriorating GT over time; (ii) insulinopenia plays a prominent role in the pathogenesis of GT worsening; (iii) IR does not play any significant part in the pathogenesis of DM development; (iv) deterioration of lung function tests is more severe in the subjects who develop DM over time.
Cow milk allergy is a common disease of infancy, often associated with atopic dermatitis (AD). Avoidance of cow milk (CM) implies the use of alternative dietary supports such as mammalian milks. In this study, we assessed the tolerability and clinical effect of ass's milk (AM), when compared with the largely used goat's milk (GM) in a single-blind, controlled, randomized crossover. Twenty-eight children with AD and ascertained allergy to CM were enrolled. The children were randomized to AM or GM for 6 months, then switched to the other milk for further 3 months. The SCORAD index (SI) and a visual analog scale (VAS) were evaluated blindly. After termination of the study, food challenges with GM and AM were performed. An SDS-PAGE analysis of different milks was performed. Two children from the GM group dropped out after randomization and 26 completed the study. Ass milk invariantly led to a significant improvement of SI and VAS of symptoms (p < 0.03 vs. baseline and inter-group), whereas GM had no measurable clinical effect. At the end of the study 23 of 26 children had a positive food challenge with GM and one of 26 with AM. Ass's milk had a protein profile closer to human milk than GM. Ass milk is better tolerated and more effective than GM in reducing symptoms of AD. It may represent a better substitute of CM than the currently used GM.
Subclinical hypothyroidism (SH) is a common clinical problem, particularly in adulthood and the elderly. Its prevalence is conditioned by several etiological and risk factors. The highest age- and sex-specific rates are in women over 60. SH may be associated with manifestations of mild thyroid failure, which may reverse under levothyroxine (L-T4) therapy. The risk of progression to overt hypothyroidism is distinctly higher in cases with underlying thyroid disease. A population routine screening is not generally recommended, but screening is encouraged in high-risk groups. L-T4 therapy may be indicated in subjects with TSH levels which are repeatedly and consistently elevated (>10 microIU/ml) and may be considered in those with TSH ranging between 4.5-5.5 and 10 microIU/ml, particularly if anti-thyroid antibodies are positive and/or hypothyroid symptoms are present. Treatment should be based, at least initially, on L-T4 low doses.
After achieving desensitization to cow milk with oral immunotherapy, a maintenance regimen with milk given twice weekly is as effective as the daily maintenance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
