RESUMO
A review of case notes from our Sydney-based paediatric allergy services, between 1 January 2003 and 31 December 2011, identified 74 children who had been prescribed diets that eliminated foods containing natural salicylates before attending our clinics. The most common indications for starting the diets were eczema (34/74) and behavioural disturbances (17/74) including attention deficit hyperactivity disorder (ADHD). We could find no peer-reviewed evidence to support the efficacy of salicylate elimination diets in managing these diseases. We do not prescribe these diets, and in a survey of European and North American food allergy experts, only 1/23 respondents used a similar diet for eczema, with none of the respondents using salicylate elimination to treat ADHD. A high proportion (31/66) of children suffered adverse outcomes, including nutritional deficiencies and food aversion, with four children developing eating disorders. We could find no published evidence to support the safety of these diets in children. While this uncontrolled study does not prove a causal relationship between salicylate elimination diets and harm, the frequency of adverse events appears high, and in the absence of evidence of safety or efficacy, we cannot recommend the use of these diets in children.

We describe a case of Q fever associated with the transient presence of antiphospholipid antibodies in a 9-year-old boy presenting with acalculous cholecystitis and splenic infarction. Antiphospholipid antibodies are commonly associated with acute Q fever in adults but have previously been thought to be of little clinical significance. Recent data suggest that antiphospholipid antibodies may be responsible for certain clinical manifestations of acute Q fever.

Sweet syndrome is an inflammatory disease characterized by fever and painful erythematous plaques with a dermal neutrophilic infiltrate. It is most common in adults, where it is often parainflammatory or paraneoplastic, but is rare in children. We describe 3 cases of neonatal Sweet syndrome, including 1 patient who had myelodysplastic syndrome and immunodeficiency, the first report of a premalignancy underlying infantile Sweet syndrome. We reviewed the literature on patients presenting with neutrophilic dermatosis in the first 6 months of life. Of 20 cases, 6 had a probable viral etiology, 4 primary immunodeficiencies, 3 neonatal lupus syndrome, 1 gastrointestinal involvement, 1 HIV, and 5 probable genetic cases. Three of these had chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome, caused by mutations in the PSMB8 gene. Most children who presented within the first 6 weeks of life had either a serious underlying condition, such as primary immunodeficiency, or a genetic Sweet syndrome, with 2 fatalities among this latter group. The outcome of postinfective cases was good. Extracutaneous involvement was unusual, whereas postinflammatory scarring and cutis laxa occurred in a minority of patients. In conclusion, Sweet syndrome in the neonatal period often heralds a serious underlying disorder and requires thorough investigation.

While the impact of infectious diseases in developed countries has been diminished by improved nutrition, hygiene, vaccination coverage and health care, infections remain common, and even the healthiest children may suffer frequent infections, occasionally necessitating admission to hospital. When investigating a child with recurrent infections, it is therefore important to know the frequency, severity, infectious syndrome and infecting organisms which a normal child might experience, and to understand the impact of the child's underlying health on their susceptibility to infection. This paper examines infectious susceptibility in the healthy and immunocompromised child and explores the respective presentations of some primary immunodeficiencies.
