A change in colour, size, shape or texture of finger- and toenails can be an indicator of underlying systemic disease. An appreciation of these nail signs, and an ability to interpret them when found, can help guide diagnosis and management of a general medical patient. This article discusses some common, and some more rare, nail changes associated with systemic disease.

Immunobullous diseases are blistering cutaneous disorders that are caused by pathogenic antibodies binding to protein targets within the skin. There are a range of immunobullous disorders with characteristic morphology that relates to the structural properties of the target protein. In this article we will describe the pathogenesis, clinical features and treatment of the most common immunobullous disorders.

Specialty and associate specialist (SAS) doctors comprise a significant proportion of the UK medical workforce.Appraisal has the potential to support professional development, as well as being vital for revalidating a doctor's licence to practise.Early research indicated that SAS doctors experienced difficulties engaging with appraisal. It is not clear if the situation has improved over recent years, and SAS doctors' voices are largely absent from the literature. ⋯ Our research reveals the importance of enhancing the professional status and agency of SAS doctors. There should be structured support and career guidance for new SAS doctors or those changing specialty and an expectation of support for professional exams. SAS doctors may benefit from explicit discussions around wellbeing. Some of these needs may be better addressed by having SAS doctors as appraisers, but this is likely to be insufficient in itself.

The new variant of concern (VOC), B.1.1.7, has a distinct set of mutations in nucleotides encoding the spike (S) protein on the surface of SARS-CoV-2. SARS-CoV-2 previously accumulated mutations at a much slower rate, of 1-2 per month; the sudden appearance of a large cluster of mutations was thought to be unusual. We now suspect that VOC may have arisen from immunosuppressed individuals who shed virus for longer periods. ⋯ VOC also has implications for the national vaccination programme - a higher proportion of people will need to be vaccinated with a more infectious virus. Prolongation of the second dose of vaccines to increase vaccine uptake has understandably caused concern, but is based on sound immunological principles. There is now an urgent need to monitor the effect of new variants on vaccine efficacy - marking a new chapter in the global fight against COVID-19.

Atopic dermatitis (AD) is a common inflammatory skin disease characterised by itch and is responsible for significant reduction in quality of life. While AD primarily arises in those under the age of 2 years, it is frequently persistent into adulthood. Recognition of AD is important for the general physician, especially to distinguish causes of acute flares that may present in any medical setting, such as eczema herpeticum and associated allergic reactions. While, to date, treatments have largely focused on broad spectrum immunomodulation with corticosteroids or systemic therapies (such as ciclosporin and methotrexate), increased knowledge in the pathophysiology of the disease has recently led to the expansion of treatment options available for those suffering with AD, and the new drugs on the horizon promise a previously unimagined potential for effective and safe treatment.
