100 years of the Royal Air Force's contribution to medicine: providing care in the air and delivering care by air.
The Royal Air Force (RAF) came into being during World War I as the world's first independent air force on the 1 April 1918, amalgamating elements of the Royal Flying Corps (RFC), itself established in 1912 and the Royal Naval Air Service which had formally separated from the Admiralty's administered Air Wing of the RFC in 1915. The RAF therefore celebrates its 100th anniversary in the same year that the Royal College of Physicians of London celebrates its 500th. This article will cover the contribution that military aviation has made to medicine since 1913 with the emphasis of three examples focusing on delivering care by air, providing care in the air and in developing systems for supporting aircrew or patients at the extremes of physiological stress.

Autologous haematopoietic stem cell transplantation (aHSCT) is commonly used for the treatment of haematological cancers, but is increasingly used in the treatment of patients severely affected by autoimmune diseases (ADs). In fact, ADs have become the fastest growing indication for aHSCT. A wide range of diseases have been treated, but the field has focused on three areas: multiple sclerosis, diffuse cutaneous systemic sclerosis and Crohn's disease, where there are populations of patients for whom disease control remains unsatisfactory despite the advent of biological and targeted small molecule therapies. ⋯ Even so, the treatment with aHSCT is intensive with a range of toxicities and risks which, despite being routine to transplant haematologists, are less familiar to disease specialists. Close collaboration between transplant haematologists and relevant disease specialists in patient selection, clinical management and follow-up is mandatory. Ideally, patients should be treated on a clinical trial if available.

Lesson of the month 2: Blunt abdominal trauma: atypical presentation of phaeochromocytoma.
A 26-year-old man presented following blunt abdominal trauma to a regional major trauma centre for emergency embolisation of a retroperitoneal bleed from a presumed renal laceration. Imaging had also revealed a large right suprarenal mass. Embolisation resulted in a hypertensive crisis raising the suspicion of a metabolically active adrenal tumour. ⋯ The patient made a gradual recovery and was discharged home with no sequelae. Definitive management of phaeochromocytoma is surgical resection which requires prolonged preoperative optimisation with alpha receptor blockers to adequately control blood pressure and prevent hypertensive crises. Parenteral alpha receptor blockers, such as phentolamine, are optimal treatment for intraoperative hypertensive emergencies, yet they are currently not available in the UK.

Widespread use of anticoagulant drugs for treatment and -prevention of thromboembolic events means it is common to encounter patients requiring reversal of anticoagulation for management of bleeding or invasive procedures. While supportive and general measures apply for patients on all agents, recent diversification in the number of licensed agents makes an understanding of drug-specific reversal strategies essential. ⋯ It is also necessary to reduce the need for reversal through correct prescribing and by employing appropriate periprocedural bridging strategies for elective and semi-elective procedures. Finally, consideration of whether and when to reintroduce an anticoagulant drug following reversal is important not only to balance bleeding and thrombotic risks for individual patients but also for timely management of discharge.
