The diagnosis and management of the dizzy patient presents the physician with significant challenges. Dizziness and imbalance are common complaints among the general population, affecting around one-third of people over the age of 65 years, and can result from a range of causes spanning many medical disciplines. ⋯ An understanding of the key features of the vestibular examination, and consideration of other pathologies including neurological and cardiac, are important. This conference was held with the aim of demystifying the dizzy patient by providing physicians with a practical approach to the assessment and management of dizziness, imbalance and 'funny turns'.

High salt intake is now endemic worldwide. It contributes to the generation and maintenance of high blood pressure, which is now the biggest risk factor for global disease. ⋯ Achieving a diet that is lower in salt has challenges, but is more likely to be achieved through salt reduction strategies particularly focused on processed food and through educational programs. To be effective, these interventions require collaboration between industry, health agencies and governments.

Acute kidney injury (AKI) is encountered commonly in HIV-positive patients admitted to the acute medical unit. The spectrum of AKI has changed in the era of combination anti-retroviral therapy, and now includes adverse effects of commonly used anti-retroviral drugs in addition to traditional precipitants such as severe sepsis or exposure to nephrotoxic antimicrobials. An accurate diagnosis requires careful integration of clinical data including volume status, history of potentially nephrotoxic exposures and consideration of immuno-virological status. This article provides an overview of common causes of AKI in HIV and presents a framework by which the acute care physician may approach the finding of an elevated serum creatinine in a patient with HIV.

Acute kidney injury (AKI) - an abrupt deterioration in renal function - causes a rise in serum creatinine (SCr) or fall in urine output. It is common, occurring in up to 20% of hospital admissions. Importantly, even small rises in SCr are associated with increased risk of death and longer hospital stays. ⋯ In practice, AKI represents a heterogeneous group of conditions, encompassing impairments in both kidney structure and function. Delivering disease-specific treatment early in the course of AKI may improve outcomes. The provision of best-practice care for all will rely on a better understanding of risk, and frameworks of care that can be applied across a diverse patient group.
