Where there is clinical equipoise in the type of diagnostic biopsy undertaken, clinicians should account for the environmental and economic impact and opt for shave biopsies, rather than punch biopsies, more frequently.

Sleep is an under evaluated symptom when assessing patients with cutaneous disease. Consequently, the relationship between sleep deprivation and disease burden is often not considered. The focus of our review article is to explore the bi-directional relationship between sleep and cutaneous disease investigating the disruption in circadian rhythmicity and skin homeostasis. Management strategies should focus on optimising disease control coupled with improving sleep hygiene.

The authors suggest two innovative methods to extract local anaesthetic from dental cartridges, thus improving the time efficiency of dermatological surgery.

Poorer outcomes are observed in vegans post-dermatologic surgery. Authors postulate impaired neocollagenesis driven by micronutrient deficiencies is the likely explanation.

This study has provided compelling evidence that traffic-related air pollution should be considered an environmental factor contributing to skin darkening and clinicians should take this into account when counselling patients.
