Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the commonest types of non-melanoma skin cancer (NMSC). The incidence of NMSC has been increasing globally with Australia recording a 1.5-fold increase over the last 17 years. Given that Australia and New Zealand share similar latitude, sun exposure levels, population skin types, and other risk factors, it is conceivable that this increase has also occurred in New Zealand. ⋯ Currently within New Zealand there is a lack of focus on the NMSC problem. The absence of New Zealand data on the incidence of NMSC has hampered the development of consistent healthcare policies (including preventative measures), that achieve an integrated and sustainable service delivery. A critical analysis of this problem based on longitudinal data is now vitally important to address this neglected problem.

Selenium is an essential mineral and severe selenium deficiency is known to cause significant health problems. It has been well documented that New Zealand soil is low in selenium. Recent studies have addressed the roles of selenoproteins in the eyes, with evidence suggesting that selenium supplementation may have a role in preventing cataract formation and age-related maculopathy. This paper summarises the role of selenium in ocular and general health and discusses selenium supplementation in a New Zealand specific context.

Human-induced climate change is now the central health issue facing humanity. The World Medical Association recently adopted the Declaration of Delhi, committing the medical profession to mitigate and adapt to the effects of climate change. This is new professional territory for many doctors. ⋯ They corroborate other evidence that tells us that CO2 and other greenhouse gases are harmful at current atmospheric concentrations. As a profession and as global citizens, we need to move beyond dissent and denial about anthropogenic climate change. The WMA correctly says that circumstances now require us all to take action.
