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.

Poor production of breast milk is the most frequent cause of breast lactation failure. Often, physician prescribe medications or other substances to solve this problem. The use of galactogogues should be limited to those situations in which reduced milk production from treatable causes has been excluded. One of the most frequent indication for the use of galactogogues is the diminution of milk production in mothers using indirect lactation, particularly in the case of preterm birth. The objective of this review is to analyze to the literature relating to the principal drugs used as galactogogues (metoclopramide, domperidone, chlorpromazine, sulpiride, oxytocin, growth hormone, thyrotrophin releasing hormone, medroxyprogesterone). Have been also analyzed galactogogues based on herbs and other natural substances (fenugreek, galega and milk thistle). We have evaluated their mechanism of action, transfer to maternal milk, effectiveness and potential side effects for mother and infant, suggested doses for galactogogic effect, and recommendation for breastfeeding.

Serum creatinine (SeCr), creatinine clearance (CrCl), and fractional excretion of sodium (FeNa) were measured in 83 preterm neonates divided into four groups according to gestational age (GA). At birth, there were no differences in mean SeCr values in the four groups nor any significant correlation between initial values and GA. In all groups there was an initial SeCr increase; an inverse correlation between SeCr and GA was observed from the 3rd day of life to the 5th week (p<0.001). CrCl showed a positive correlation to GA from the first week onwards (p<0.001); in each group CrCl values correlated positively to days of life (p=0.0001). Rate of CrCl increase correlated positively to GA (p=0.0005). FeNa showed an inverse correlation to GA from the first week (p<0.001). In each group, the FeNa value correlated negatively to postnatal age (p<0.001) and the velocity of decrease was directly correlated to GA (p=0.0358). Our findings indicate that glomerular function shows a progression directly correlated to GA and postnatal age, while tubular function correlates inversely to the same parameters. The values reported could be useful for following renal function in very low birth weight infants.

Preterm neonates with sepsis, pneumonia or necrotising enterocolitis showed increased interleukin-6, interleukin-10 and C-reactive protein levels. High interleukin-10 concentration was associated with mortality and could be an early indicator of prognosis.
