Acute inhalation lung injury secondary to zinc and copper aspiration from food contact dust.

A previously healthy boy of preschool age was brought to the emergency department by ambulance with respiratory distress following the accidental inhalation of food contact dust (cake decorating powder). Prehospital oxygen saturations were 80% in room air. Initial treatment was with oxygen, nebulised salbutamol, oral dexamethasone and intravenous amoxicillin/clavulanic acid. Treatment was escalated to nasal high flow oxygen therapy and high dependency care within 8 hours. Lung fields on his initial chest X-ray were clear but the following day showed perihilar infiltrates extending into the lower zones in keeping with inflammation. He was treated with intravenous methylprednisolone, followed by a weaning dose of oral prednisolone over 14 days.He required oxygen therapy for 9 days and remained in hospital for 11 days. Outpatient follow-up, 24 days after the inhalation took place was reassuring with the child showing no signs of abnormal respiratory symptoms.

Empowering children and young people who have asthma.

Asthma is the most common chronic condition of childhood. In this review, we discuss an overview of strategies to empower children and young people with asthma. The key aspects of empowerment are to enable shared decision making and self-management, and help children minimise the impact of asthma on their life. The evidence behind these strategies is either sparse or heterogenous, and it is difficult to identify which interventions are most likely to improve clinical outcomes. Wider determinants of health, in high-resource and low-resource settings, can be disempowering for children with asthma. New approaches to technology could help empower young people with asthma and other chronic health conditions.

Cystic fibrosis newborn screening: outcome of infants with normal sweat tests.

Newborn babies positively screened for cystic fibrosis (CF) (high serum immunoreactive trypsin (IRT) with DNA analysis) are referred for a diagnostic sweat test, which may be normal (sweat chloride <30 mmol/L). Unless two gene mutations are identified during Newborn screening (NBS), the babies are discharged from follow-up. We wished to check that none had subsequently developed symptoms suggestive of CF. We retrospectively reviewed patient notes and contacted general practitioners of all babies with a negative sweat test, conducted in one of the four paediatric specialist CF centres in London, over the first 6 years of screening in South East England.Of 511 babies referred, 95 (19%) had a normal sweat test. Five (5%) had CF diagnosed genetically, two of them on extended genome sequencing after clinical suspicion. Eleven (12%) were designated as CF screen positive inconclusive diagnosis (CFSPID); one of the five CF children was originally designated as CFSPID. Seventy-nine (83%) were assumed to be false-positive cases and discharged; follow-up data were available for 51/79 (65%); 32/51 (63%) had no health issues, 19/51 (37%) had other significant non-CF pathology.These results are reassuring in that within the limitations of those lost to follow-up, CF symptoms have not emerged in the discharged children. The high non-CF morbidity in these children may relate to known causes of high IRT at birth. Clinicians need to be aware that a child can have CF despite a normal sweat test following NBS, and if symptoms suggest the diagnosis, further testing, including extended genome sequencing, is required.

Sleep Disordered Breathing in Children.

Sleep-disordered breathing (SDB) refers to a group of disorders characterized by abnormalities of respiration or ventilation during sleep. It encompasses obstructive sleep apnea (OSA), central sleep apnea (CSA) syndromes, sleep-related hypoventilation and sleep-related hypoxemia disorders. This review will concentrate on the disorder most prevalent in pediatrics, i.e., OSA, highlighting the most recent developments in our understanding of the etiology, pathophysiology and treatment options of this condition. OSA morbidities primarily involve the neurocognitive, cardiovascular and metabolic systems. However, there can be significant phenotypic variation in terms of end organ morbidity for the same OSA severity. This is likely due to the interplay between genetic and environmental factors; recent developments in the fields of genomics and proteomics have the potential to shed light on these complex pathological cascades. As we enter the era of personalized medicine, phenotyping patients to enable clinicians to tailor bespoke clinical management plans will be of crucial importance.

Critical timing of gastrostomy insertion in a child with cystic fibrosis.

Pulmonary exacerbations and malabsorption in children with cystic fibrosis (CF) can lead to faltering growth and poor weight gain. Children with a higher BMI (body mass index) show a slower decline in lung function. Our specialist CF centre has experienced a death following gastrostomy insertion in a young CF child, despite maximal medical intervention, which has made us reflect on our practice and the urgency with which we discuss the option for a gastrostomy to improve nutrition.

Increasing early protein intake is associated with a reduction in insulin-treated hyperglycemia in very preterm infants.

BACKGROUND: Impaired early protein intake in very preterm infants contributes to early growth failure and may affect long-term neurocognitive development. The authors have previously shown that a standardized concentrated neonatal parenteral nutrition (scNPN) formulation can improve the efficiency of early protein administration. They recognized that very early protein intake could be improved further by modifying the original scNPN regimen and starting PN within 4 hours. AIM: To demonstrate that the new scNPN regimen could improve very early protein intake in infants <29 weeks' gestation without causing clinically important PN intolerance and complications. METHODS: All eligible infants <29 weeks' gestation, receiving the modified scNPN regimen and born between October 2009 and December 2010, were studied (group scNPN2). These were compared with previously studied infants, <29 weeks' gestation and receiving the original scNPN regimen and born between June 2006 and December 2006 (group scNPN1). Infant details, actual nutrition intake, and metabolic/infection data were recorded. RESULTS: Thirty-eight infants <29 weeks' gestation (group scNPN2) were compared with the 38 infants previously studied (group scNPN1). PN was started earlier in group scNPN2, leading to increased mean (95% confidence interval) total protein intake (first 7 days) of 15.3 (14.5-16.1) g/kg in group scNPN2 vs 11.8 (11.0-12.6) g/kg in group scNPN1. There were no differences in calorie, lipid, and carbohydrate intake. Infants receiving insulin for hyperglycemia fell from 20 (53%) in group scNPN1 to 10 (26%) in group scNPN2. CONCLUSION: Increasing early protein intake is associated with a reduction in insulin-treated hyperglycemia in infants <29 weeks' gestation.
