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.

Pregnancy is accompanied by metabolic changes associated with the thyroid gland. It is therefore important to understand the underlying physiological alterations and the management of patients with thyroid disorders in pregnancy. This review focuses on the physiology and the management of hyperthyroidism, hypothyroidism and thyroid nodules in the context of pregnancy.

We describe an active and latent tuberculosis (TB) screening programme undertaken in Manchester, UK in response to the arrival of a cohort of refugees from Afghanistan. In total, 217 adults and 347 children were offered screening, which involved a symptom questionnaire, Mantoux test or interferon gamma release assay, blood-borne virus screening and a chest X-ray in participants over the age of 11. We found a latent TB infection (LTBI) rate of 15% in adults and 1.5% in children, which is lower than global LTBI estimates. ⋯ Attendance rates were almost doubled compared with a previous hospital-based screening programme. Hotel-based screening for TB presented several challenges, including transfer of information and results to secondary care. Understanding these challenges and learning from the programme has helped us refine our screening protocol to optimise migrant TB screening in Manchester in the future.

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.

With the increasing volume of diagnostic imaging undertaken in an ageing population, adrenal incidentalomas (AIs) are increasingly commonly seen. These masses are most likely to be benign, but a small proportion may be malignant. Similarly, they are usually non-functional, but ∼14% are functional, ie hormone-secreting tumours. ⋯ Functional tumours where excess cortisol, aldosterone or catecholamine are secreted should be excluded, with mild autonomous cortisol secretion (MACS) and primary aldosteronism (PA) as the two most common functional states. MACS and PA are associated with an increased risk of cardiometabolic disease (eg hypertension, type 2 diabetes) and cardiovascular morbidity/mortality (eg coronary heart disease). Multidisciplinary management is critical for selected cases; the majority of adrenal incidentalomas only require a single assessment.
