Clinical medicine (London, England)

Established as a medical specialty in 1987, palliative medicine approaches middle age facing existential questions of identity, purpose and vision. Time has weakened strong foundations laid by Dame Cicely Saunders in research, education and clinical excellence. Clinical knowledge gaps are wide, and widening. ⋯ Experience shows that caution must be applied where the evidence base is sparse. While as a specialty we must remain forward looking and progressive in our mindset, it cannot be assumed that these new interventions alone will provide the solutions to the old problems that exist in palliative medicine. This review summarises the key points presented in the Palliative Medicine section of the RCP Clinical Medicine Conference, 2022.

The supply of blood, blood products and components in the UK, as elsewhere, is safe, although there is no cause for complacency. Use of blood, blood products and components is not without risk of morbidity and mortality. Transfusion-transmitted infections (TTIs) continue to occur and may severely affect the health and welfare of recipients. ⋯ The introduction of newer screening tests might identify some infectious donations but come at a cost, which could exceed a justifiable limit. Thus, the recognition, detection, reporting and investigation of cases of possible TTIs need to be improved. Recipients of blood should understand that, although transfusion in the UK is safe, it is not free of risk and so should be provided with full information so that properly informed consent can be given.

Neuroendocrine tumours (NETs) represent a heterogenous group of tumours, with diversity in their primary tumour sites, functional status (ie hormone secreting or non-functional) and degrees of aggressiveness (ranging from well-differentiated, grade 1 neuroendocrine tumours to poorly differentiated grade 3, neuroendocrine carcinomas). The most common sites are the lung, small bowel, pancreas and appendix. ⋯ Treatment comprises surgery where curative resection is possible through to approaches where disease stabilisation is the key, involving somatostatin analogues, peptide receptor radionuclide therapy (PRRT), everolimus, sunitinib, liver-directed therapies and sometimes chemotherapy. Although local and systemic complications can occur, they are associated with reasonable 5- and 10-year survival rates, respectively.

Case Reports
Nitrous oxide misuse: a clue not to be missed in young patients with venous thromboembolism.
A 27-year-old man presented with altered mental status and unilateral right lower limb swelling. Brain imaging and cerebrospinal fluid analysis were unremarkable. He reported history of nitrous oxide misuse after he recovered from his delirium. ⋯ Raised homocysteine is associated with increased thrombosis risk. Fourteen cases of nitrous oxide misuse associated arterial and venous thrombosis have been reported. These two cases highlighted the importance of inquiring about recreational drug use in young patients who presented with apparently unprovoked venous thromboembolism.

Pituitary incidentalomas are common findings with increasing use of modern neuroradiological imaging undertaken for symptoms unrelated to pituitary disease. The prevalence of these lesions is ∼10% in autopsy studies and the incidence varies from 10% to 38% on magnetic resonance imaging in the published literature. ⋯ All identified cases should have a thorough clinical and endocrinological evaluation to help with precise management, which depends on the size of the lesion, hormonal status (functioning versus non-functioning adenoma) and the presence of visual deficits resulting from optic nerve compression by the pituitary adenoma. Here, we provide an overview of the initial assessment and management of pituitary incidentalomas for clinicians not routinely involved in the management of pituitary disease.
