Acute bronchiolitis is the leading cause of lower respiratory tract infection and hospitalization in children less than 1 year of age worldwide. It is usually a mild disease, but some children may develop severe symptoms, requiring hospital admission and ventilatory support in the ICU. Infants with pre-existing risk factors (prematurity, bronchopulmonary dysplasia, congenital heart diseases and immunodeficiency) may be predisposed to a severe form of the disease.Clinical diagnosis of bronchiolitis is manly based on medical history and physical examination (rhinorrhea, cough, crackles, wheezing and signs of respiratory distress). Etiological diagnosis, with antigen or genome detection to identify viruses involved, may have a role in reducing hospital transmission of the infection.Criteria for hospitalization include low oxygen saturation (<90-92%), moderate-to-severe respiratory distress, dehydration and presence of apnea. Children with pre-existing risk factors should be carefully assessed.To date, there is no specific treatment for viral bronchiolitis, and the mainstay of therapy is supportive care. This consists of nasal suctioning and nebulized 3% hypertonic saline, assisted feeding and hydration, humidified O2 delivery. The possible role of any pharmacological approach is still debated, and till now there is no evidence to support the use of bronchodilators, corticosteroids, chest physiotherapy, antibiotics or antivirals. Nebulized adrenaline may be sometimes useful in the emergency room. Nebulized adrenaline can be useful in the hospital setting for treatment as needed. Lacking a specific etiological treatment, prophylaxis and prevention, especially in children at high risk of severe infection, have a fundamental role. Environmental preventive measures minimize viral transmission in hospital, in the outpatient setting and at home. Pharmacological prophylaxis with palivizumab for RSV bronchiolitis is indicated in specific categories of children at risk during the epidemic period.Viral bronchiolitis, especially in the case of severe form, may correlate with an increased incidence of recurrent wheezing in pre-schooled children and with asthma at school age.The aim of this document is to provide a multidisciplinary update on the current recommendations for the management and prevention of bronchiolitis, in order to share useful indications, identify gaps in knowledge and drive future research.
In our experience, radical resection of CP represented the first and almost unique treatment modality. Although not insignificant, post-operative mortality and morbidity do not seem to represent a major contraindication in attempting a radical tumour resection whenever possible. On the other hand, extensive hypothalamic involvement should suggest a less aggressive attitude.
Purpose Covid-19 is a pandemic of unprecedented proportion, whose understanding and management is still under way. In the emergency setting new or available therapies to contrast the spread of COVID-19 are urgently needed. Elderly males, especially those affected by previous diseases or with comorbidities, are more prone to develop interstitial pneumonia that can deteriorate evolving to ARDS (acute respiratory distress syndrome) that require hospitalization in Intensive Care Units (ICUs). Even children and young patients are not spared by SARS-CoV 2 infection, yet they seem to develop a milder form of disease. In this setting the immunomodulatory role of Vitamin D, should be further investigated. Methods: We reviewed the literature about the immunomodulatory role of Vitamin D collecting data from the databases Medline and Embase. Results Vitamin D proved to interact both with the innate immune system, by activating Toll-like receptors (TLRs) or increasing the levels of cathelicidins and β-defensins, and adaptive immune system, by reducing immunoglobulin secretion by plasma cells and pro-inflammatory cytokines production, thus modulating T cells function. Promising results have been extensively described as regards the supplementation of vitamin D in respiratory tract infections, autoimmune diseases and even pulmonary fibrosis. Conclusions In this review, we suggest that vitamin D supplementation might play a role in the prevention and/or treatment to SARS-CoV-2 infection disease, by modulating the immune response to the virus both in the adult and pediatric population.
The two major autoimmune thyroid diseases (ATDs) include Graves' disease (GD) and autoimmune thyroiditis (AT); both of which are characterized by infiltration of the thyroid by T and B cells reactive to thyroid antigens, by the production of thyroid autoantibodies and by abnormal thyroid function (hyperthyroidism in GD and hypothyroidism in AT). While the exact etiology of thyroid autoimmunity is not known, it is believed to develop when a combination of genetic susceptibility and environmental encounters leads to breakdown of tolerance. It is important to recognize thyroid dysfunction at an early stage by maintaining an appropriate index of suspicion.
Coeliac disease, elevated TSH and TPOAb at presentation and a progressive increase in TSH are predictive factors for thyroid failure in HT patients.
OBJECTIVEWe investigated whether supplementation of the active form of vitamin D (calcitriol) in recent-onset type 1 diabetes can protect β-cell function evaluated by C-peptide and improve glycemic control assessed by A1C and insulin requirement.RESEARCH DESIGN AND METHODSThirty-four subjects (aged 11–35 years, median 18 years) with recent-onset type 1 diabetes and high basal C-peptide >0.25 nmol/l were randomized in a double-blind trial to 0.25 μg/day calcitriol or placebo and followed-up for 2 years.RESULTSAt 6, 12, and 24 months follow-up, A1C and insulin requirement in the calcitriol group did not differ from the placebo group. C-peptide dropped significantly (P < 0.001) but similarly in both groups, with no significant differences at each time point.CONCLUSIONSAt the doses used, calcitriol is ineffective in protecting β-cell function in subjects (including children) with recent-onset type 1 diabetes and high C-peptide at diagnosis.
In this study, we report the clinical presentation, response to medical treatment, and long-term follow-up of 26 patients with prolactinoma (15 macro- and 11 micro-adenomas) diagnosed at the age of 7-17 yr. All patients were first treated with bromocriptine (BRC) at doses ranging from 2.5-20 mg/day orally. BRC was discontinued for intolerance and/or resistance to the drug and was replaced by quinagolide (CV) at doses ranging from 0.075-0.6 mg/day or by cabergoline at doses ranging from 0.5-3.5 mg/week orally. Two patients received external conventional radiotherapy after surgery. In 7 prepubertal males and 6 females with macroprolactinoma, headache and/or visual defects were the first symptoms. All females presented with primary or secondary amenorrhea. Growth arrest was observed in a male patient with microadenoma, whereas all the remaining patients had normal heights, and pubertal development was appropriate for their age. Spontaneous or provocative galactorrhea was observed in 12 patients (3 males and 9 females) and gynecomastia in 4 males. Mean serum PRL concentration (+/-SE) at the time of diagnosis was 1080 +/- 267 microg/L in patients with macroadenoma and 155 +/- 38 microg/L in patients with microadenoma. In 10 patients, BRC normalized PRL levels and caused variable, but significant, tumor shrinkage. CV normalized PRL concentrations and reduced tumor size in 5 patients. Cabergoline normalized PRL concentrations in 7 of 10 patients resistant to CV. Pregnancy occurred in 2 patients while on treatment. Pregnancies were uncomplicated, and the patients delivered normal newborns at term. Only 4 patients are still moderately hyperprolactinemic. Impairment of other pituitary hormone secretion was documented at the time of diagnosis in 7 patients, 5 of whom underwent surgery. Four patients became GH deficient in adult age. In conclusion, the medical treatment with dopaminergic compounds is effective and safe in patients with prolactinoma with onset in childhood, allowing preservation of the anterior pituitary function.
