A 9-month-old boy presents to the emergency department following development of a rapidly growing rash. Mum reports that he was feverish and irritable yesterday evening, but this morning she found him agitated and crying, with large fluid-filled blisters on his chest, so she immediately brought him to the hospital. He was born at 35+5 weeks by spontaneous vaginal delivery and spent 2 days in the neonatal intensive care unit owing to respiratory distress. He made a good recovery, and has been healthy since, with no concerns over his developmental milestones. He has no other medical conditions, takes no regular medications and has no known drug allergies.

On examination, he is miserable and pyrexial, with a widespread blistering red rash across 90% of the surface of his skin. The oral mucosa is spared. Slight pressure on the skin causes peeling of the superficial epidermis.

Bloods reveal a raised CRP and WCC, normal LFTs and clotting profile. The ECG shows second-degree heart block.

What is the most likely diagnosis?

Answer 23

Acute rheumatic fever

The patient has presented with two major (arthritis and erythema marginatum) and two minor (heart block on ECG and fever) criteria for acute rheumatic fever. Although there has been no mention of a group A strep infection, the combination of these symptoms in a patient between 5-15 years old point strongly towards this diagnosis. Some strep infections may not be noticed by patients (particularly if a mild skin infection), or may not be identified when taking the history from the patient or their parents. This can lead to clinicians overlooking rheumatic fever as a diagnosis

Which of the following is the most likely cause of this patient's acute otitis media?

Answer 29

Measles is an RNA paramyxovirus and is one of the most infectious viruses spread by aerosol transmission. However, it is rarely seen in the developed world due to the immunisation programmes (MMR). The most common complication of measles is otitis media, whereas the most common cause of death is pneumonia.
