Myelodysplastic syndromes (MDS) are a group of blood cancers involving dysregulated haematopoiesis, which may progress to acute myeloid leukaemia. This Primer provides an overview of the epidemiology, diagnosis, pathogenesis and management of MDS.

Asplenia and hyposplenism can have multiple and complex causes and lead to morbidity and mortality, especially owing to overwhelming post-splenectomy infections. In this Primer, Lenti and colleagues review epidemiology, pathophysiology, diagnosis and management of these conditions, and discuss patient quality of life and future strategies.

Gallbladder cancer is the most common cancer of the biliary tract and often has a very poor prognosis. This Primer by Roa and colleagues summarizes the epidemiology, mechanisms, diagnosis and treatment of gallbladder cancer, and discusses patient quality of life and open research questions for this disease.

Fracture-related infection, involving infiltration of pathogenic bacteria into a wound that delays bone healing, is a common complication of bone fracture fixation. This Primer reviews the epidemiology, pathobiology, diagnosis and management of these infections and their impact on patient quality of life.

Small round cell sarcomas are a group of aggressive tumours of bone and soft tissue that result from specific genetic alterations and fusions, typically involving EWSR1, BCOR or CIC. This Primer reviews the epidemiology, pathogenesis, diagnosis, and management of these entities and the effects of the tumour and its treatment on quality of life.

Adult-onset autoimmune diabetes can occur as classic type 1 diabetes but mostly has a slow progression and a long period not requiring insulin; it is often misdiagnosed as type 2 diabetes. This Primer by Buzzetti and colleagues summarizes the epidemiology, mechanisms, diagnosis and treatment of this disorder, and summarizes patient quality of life and open research questions.

Urticaria is an inflammatory skin disorder that presents with itchy wheals and/or angioedema mediated by skin mast cells and release of histamine and other mediators. This Primer by Kolkhir et al. summarizes the epidemiology, mechanisms, diagnosis and treatment of urticaria, and discusses patient quality of life and open research questions for this condition.
