SummaryIcatibant is a selective bradykinin 2 receptor antagonist, currently licensed for use in hereditary angioedema. Its benefit in ACE inhibitor angioedema is yet to be fully established. A handful of preliminary case reports suggest that it may be of benefit in reducing both symptom severity and possible hospital or intensive care admission. To date, there are no case reports of the usage of Icatibant in the emergency department in the UK. Here we report our experience of Icatibant in a 62-year-old gentleman presenting with severe oral, pharyngeal and laryngeal oedema while on an ACE inhibitor. BACKGROUND

Malignant otitis externa associated with skull base osteomyelitis is a condition seen classically in the elderly, diabetic patient. This disease is difficult to manage, often requiring long-term antibiotic therapy. Here we present such a case, seen in a 74- year-old lady. Initially, she was treated for a number of years in the outpatient department with intermittent ear complaints, but eventually required a hospital admission that lasted for 6 months due to a severe malignant otitis externa complicated by skull base osteomyelitis. We will discuss the clinical features, diagnostic criteria, imaging and management of this life-threatening clinical entity.

A previously fit and well 44-year-old gentleman was admitted with a 3-week history of parotid swelling, malaise and feeling generally unwell. His only medical history was α-thalassaemia trait. Initial ear, nose and throat examination was unremarkable. Routine observations highlighted tachycardia, hypotension and a raised respiratory rate. Despite fluid resuscitation, his hypotension failed to resolve and he was admitted to intensive care for inotropic support. He was started on broad spectrum antibiotics and blood cultures isolated Lancefield group A Streptococcus. No obvious source of sepsis was identified. A CT scan from neck to pelvis highlighted a collection around the right tonsil, splenomegaly and widespread small volume lymphadenopathy. A right tonsillectomy, intraoral drainage of parapharyngeal and retropharyngeal abscesses and excision of an axillary lymph node were performed. With continued intravenous antibiotics and supportive measures, he recovered fully. Histology showed reactive lymphadenitis, but no cause of immunocompromise.
