Psoriasis is a chronic, immune-mediated inflammatory skin disease affecting 1.3-2.2% of the UK population.1 Most commonly, psoriasis is characterised by well-demarcated, red plaques with adherent scale with a predilection for the scalp and extensor surfaces of the limbs. However, the effects of psoriasis go far beyond a patient's skin and may result in a degree of disability and impaired quality of life similar to that of other major medical conditions, such as cancer and heart disease. First-line therapies for most patients are topical treatments such as topical corticosteroids and vitamin D analogues. ⋯ Aside from the visible skin disease, psoriasis is also increasingly recognised to have important systemic manifestations. Psoriatic arthritis has long been established as an associated condition and, more recently, it has emerged that psoriasis is also associated with an increased risk of inflammatory bowel disease, cardiovascular disease and the metabolic syndrome. Both National Institute for Health and Care Excellence (NICE)2 and Scottish Intercollegiate Guidelines Network (SIGN)3 have recently published guidelines for the assessment and management of psoriasis which highlight the need for regular assessment in order to detect the development of arthritis and the presence of other co-morbidities such as obesity, diabetes, dyslipidaemia and hypertension.

Occupational medicine represents the interface between work and health. As such, its breadth encompasses issues of clinical medicine, epidemiology, occupational hygiene, toxicology, ethics, and the law. ⋯ It is not surprising that many clinicians find this challenging. The aim of this paper is to provide a summary of common work-related lung disorders, and stress the importance of considering a patients' occupation when presented with a range of respiratory symptoms.

Hyperkalaemia, an elevated extracellular fluid potassium concentration, is a common electrolyte disorder and is present in 1-10% of hospitalised patients. Elevated serum potassium concentrations are usually asymptomatic but may be associated with electrocardiogram (ECG) changes. Hyperkalaemia occasionally leads to life-threatening cardiac arrhythmias. ⋯ Nebulised β-2 adrenoceptor agonists can augment the effects of intravenous insulin and glucose pending more definitive management of the recurrent hyperkalaemia risk. Additional management steps include stopping further potassium intake and careful review of prescribed drugs that may be adversely affecting potassium homeostasis. Changes to prescribing systems and an agreed institutional protocol for management of hyperkalaemia can improve patient safety for this frequently encountered electrolyte disorder.

Acute kidney injury (AKI) represents a medical emergency associated with poor clinical outcomes. The international guideline group Kidney Disease: Improving Global Outcomes (KDIGO) has defined AKI according to rises in serum creatinine and/or reductions in urine output. Any patient who meets the criteria for AKI should be reviewed to ascertain the cause of AKI and the severity of the injury should be staged. ⋯ The optimal choice of intravenous fluid therapy remains controversial. There is currently renewed interest in more specific therapies for AKI secondary to hypoperfusion and/or sepsis, which have been previously unsuccessful. A number of therapeutic strategies are presently being explored in clinical trials.
