A 5-year-old boy with an incidentally detected cardiac murmur was referred for evaluation. Tall R waves were noted in the electrocardiogram in leads V3 and V4. Transthoracic echocardiography suggested asymmetric septal hypertrophy with diffuse thickening of the inter-ventricular septum with normal thickness of the posterior left ventricular wall. Upon closer interrogation, a masquerading sessile cardiac mass was identified adherent to the left ventricular side of the inter-ventricular septum which appeared to contract with each cardiac cycle, mimicking hypertrophic cardiomyopathy.

An 18-year-old female patient presented to the emergency department with non-specific neurological and gastrointestinal symptoms and was found to be pancytopenic. Her vitamin B12 level was low with a normal mean corpuscular volume and her full blood count 2 months previously had been within normal range. ⋯ Her pancytopenia resolved with discontinuation of nitrous oxide and vitamin B12 treatment. Heavy use of nitrous oxide should be considered as a cause of pancytopenia.

Flucloxacillin, a beta-lactam antibiotic, is a commonly prescribed antibiotic for the treatment of infections caused by staphylococci and streptococci, most notably Staphylococcus aureus Paracetamol is one of the most dispensed medications by NHS England and is used for the treatment of fever and pain.1 However most doctors are unaware that concurrent use of these drugs can cause a potentially fatal drug interaction due to pyroglutamic acidosis (PGA), also known as 5-oxoprolinaemia. PGA is a rare cause of raised anion gap metabolic acidosis due to disruption of the γ-glutamyl cycle. We report the case of a patient with multiple comorbidities who developed PGA due to coadministration of paracetamol and flucloxacillin.

Despite concerted efforts to eliminate malaria, it remains a major global cause of morbidity and mortality with over 200 million annual cases. Significant gains have been made, with the annual global malaria incidence and mortality halving over the past twenty years, using tools such as long-lasting insecticide-treated bed nets and artemisinin-based therapies. ⋯ The difference between a good and poor outcome is early diagnosis and treatment. Many of the challenges faced in the quest for global eradication, such as availability of appropriate diagnostic tests, and drug and insecticide resistance could also have future implications for imported malaria.

Climate change is already expanding the geographic footprint of arboviral infections. In this article we consider the impact of climate change on three arboviruses with particular consideration of the effect on Europe.
