Breastfed infants have a reduced risk of becoming overweight and/or obese later in life. This protective effect has been partly attributed to leptin present in breastmilk. This study investigated 24-h variations of skim milk leptin and its relationship with breastmilk macronutrients and infant breastfeeding patterns. Exclusive breastfeeding mothers of term singletons (n = 19; age 10 ± 5 weeks) collected pre- and post-feed breastmilk samples for every breastfeed over a 24-h period and test-weighed their infants to determine milk intake at every breastfeed over a 24-h period. Samples (n = 454) were analysed for leptin, protein, lactose and fat content. Skim milk leptin concentration did not change with feeding (p = 0.184). However, larger feed volumes (>105 g) were associated with a decrease in post-feed leptin levels (p = 0.009). There was no relationship between the change in leptin levels and change in protein (p = 0.313) or lactose levels (p = 0.587) between pre- and post-feed milk, but there was a trend for a positive association with changes in milk fat content (p = 0.056). Leptin concentration significantly increased at night (p < 0.001) indicating a possible 24-h pattern. Leptin dose (ng) was not associated with the time between feeds (p = 0.232). Further research should include analysis of whole breastmilk and other breastmilk fractions to extend these findings.

Children with red swollen eyes frequently present to emergency departments. Some patients will have orbital cellulitis, a condition that requires immediate diagnosis and treatment. Orbital cellulitis can be confused with the less severe, but more frequently encountered, periorbital cellulitis, which requires less aggressive management. Delayed recognition of the signs and symptoms of orbital cellulitis can lead to serious complications such as blindness, meningitis and cerebral abscess. This article describes the clinical features, epidemiology and outcomes of the condition, and discusses management and treatment. It also includes a case study.

BackgroundInfants breastfed on demand exhibit a variety of feeding patterns and self-regulate their nutrient intake, but factors influencing their gastric emptying (GE) are poorly understood. Despite research into appetite regulation properties of leptin, there is limited information about relationships between human milk leptin and infant GE.MethodsGastric volumes were calculated from ultrasound scans of infants' stomachs (n=20) taken before and after breastfeeding, and then every 12.5 min (median; range: 3-45 min) until the next feed. Skim milk leptin and macronutrient concentrations were measured and doses were calculated.ResultsThe leptin concentration was (mean±SD) 0.51±0.16 ng/ml; the leptin dose was 45.5±20.5 ng per feed. No relationships between both concentration and dose of leptin and time between the feeds (P=0.57; P=1, respectively) or residual stomach volumes before the subsequent feed (P=0.20; P=0.050) were found. Post-feed stomach volumes (GE rate) were not associated with leptin concentration (P=0.77) or dose (P=0.85).ConclusionGE in term breastfed infants was not associated with either skim milk leptin concentration or dose. Further investigation with inclusion of whole-milk leptin and other hormones that affect gastrointestinal activity is warranted.

Febrile convulsions (FCs) are characterised by convulsions associated with fever in children aged between 6 months and 6 years. FCs are relatively common and affect 3–4% of children in western countries. This is the most common seizure disorder seen in children. The cause of febrile illness in FC is usually benign and most frequently due to acute viral infection. Convulsions secondary to an intracranial infection (e.g. meningitis, encephalitis) or from acute electrolyte imbalance should not be labelled as FCs. The diagnosis is based mainly on clinical history, and further investigations are generally unnecessary; management is largely symptomatic. Prolonged FC may need anticonvulsant medication to stop the seizure. Referral to paediatric neurologists may be considered in cases of complex or recurrent FC or in children where there is a pre-existing neurological disorder. One third of children with a first FC will develop a further FC during subsequent febrile illness; the likelihood increases in presence of other risk factors. This article outlines the presentation, management, investigations and prognosis for FC, and highlights how nurses in different clinical settings can provide education, support and counselling to help families return to normality after the event. An illustrative case study is also included to highlight the challenges faced by health professionals while managing children with this condition.

Brain tumours comprise over one quarter of all childhood cancers in the UK and are the most common cause of cancer-related deaths in children. The presentation of brain tumours can vary substantially in children. The presenting symptoms are often similar to less serious conditions, and are often managed as such initially. Therefore, it can be difficult to diagnose brain tumours in children. An early diagnosis is usually associated with more effective treatment and improved health outcomes. The diagnostic interval between first presentation to a health professional and diagnosis for brain tumours in children has been shown to be three times longer in the UK than in other developed countries. As a result, the HeadSmart campaign launched a symptom card in 2011 to increase awareness of brain tumours in children among the general population and healthcare professionals, with the aim of reducing the diagnostic interval to 5 weeks. Nurses have an essential role in early recognition of brain tumours in children, and in providing care and support to the child and their family following a diagnosis.

Neonatal sepsis describes serious bacterial or viral infections that manifest in the first 28 days of life, causing significant morbidity and mortality. Although most babies with early-onset neonatal sepsis are born and managed in hospital, some are born in the community, or discharged early from postnatal wards. Consequently, emergency department (ED) nurses and other healthcare professionals need to be able to identify and treat these infants effectively to improve long-term outcomes. This article discusses neonatal sepsis, including causative organisms, types of neonatal sepsis and why neonates are vulnerable to infection. The National Institute for Health and Care Excellence 2012 and 2014 guidance is also discussed in relation to management of neonatal sepsis and a case study is included to illustrate some of the challenges that ED nurses may encounter.
