SUMMARY BackgroundAllergy and functional gastrointestinal disorders have been associated with eosinophilia in duodenal mucosa.

A 13-year-old girl presents to the emergency department for the second time with an unresponsive episode. She has a GCS (Glasgow Coma Scale) score of 11 on arrival and all other observations are normal. The story is unclear, but there are ongoing safeguarding concerns and the family are known to social services. All investigations are normal. After a period of observation on the ward, her GCS returns to normal and she appears well. Both on the first presentation and this presentation ingestion of a toxin was suspected. However, this was denied by the patient and urine toxicology screen was negative. Does this rule out toxin ingestion? Will this change your management?

Group B streptococcus (GBS) is recognised as one of the leading organisms in early-onset neonatal sepsis but is also a cause of late-onset GBS septicaemia, meningitis and rarely, infective endocarditis (IE). We report a case of a healthy term neonate who developed GBS septicaemia and meningitis having presented with parental concern and poor feeding. Subsequent identification and treatment of GBS resulted in the requirement for long-line intravascular access in order to administer antibiotic therapy. One week later, after repeated parental concern and symptoms of shortness of breath, the neonate presented to Accident and Emergency and subsequently a Paediatric Cardiorespiratory Intensive Care Unit where emergency resuscitation procedures were required and diagnosis of severe IE affecting the mitral valve was made. Mitral valve replacement was complicated with significant morbidity and prolonged hospitalisation. An innovative procedure to insert a Melody valve was successful.
