But how are they best treated? Ina Farrelly is a senior podiatrist at Mile End Hospital in London.We often hear how difficult it is to get a GP appointment.

They also save the healthcare system over £300. Professor Cathy Warwick, chief executive of the Royal College of Midwives, tells Inside Health that adoption of this "caseload" model in the UK has been slow.Around half a million people in the UK have some form of leg ulcer, and up until recently many would have them dressed in the community for years, without the underlying cause ever being diagnosed and treated. But this now looks set to change, as new guidance published by NICE recommends that if ulcers last more than two weeks, patients should be referred to a specialist vascular clinic.

New research has found an association between Pandemrix, a swine flu vaccine, and a rare sleep disorder in children. Fears about a pandemic of H1N1 flu, so called "swine flu", over the winter of 2009/2010 led to millions of vulnerable people across the UK, including every child under five, being offered a new vaccine.

The Traditional Herbal Medicines Registration Scheme was brought in by the Medicines Healthcare Products Regulatory Agency (MHRA) in 2005. But there are concerns that the threshold for this type of licensing is set too low, and is misleading consumers. To debate the issue, Mark Porter is joined by resident sceptic Margaret McCartney and Dr Linda Anderson from the licensing division at the MHRA. It is thought that around five million people in the UK, most of them women, take some form of high dose calcium supplement to keep their bones healthy.
