A Dutch doctor who exploited vulnerable people with multiple sclerosis by charging them thousands of pounds for unproven stem cell treatments has been banned from practice in the UK by the General Medical Council. Robert Trossel, 56, who practised in London and Rotterdam, gave “false hope and made unsubstantiated and exaggerated claims to patients suffering from degenerative and devastating illnesses,” said GMC fitness to practise panel chairman Brian Gomes da Costa. The panel held that Dr Trossel’s misconduct was “fundamentally incompatible with being a doctor” and ordered that his name be erased from the UK medical register with immediate effect.
