Recent articles in this journal 1,2 have focused attention on the growing body of evidence showing that steroid hormones can alter brain function in novel ways. The autocrine and paracrine roles played by steroids synthesized in the brain (also known as neurosteroids) are yet to be fully elucidated. The physiological properties of known neurosteroids are diverse, and differ temporally (neurodev...

Since the term odontogenic keratocyst first appeared in the literature, controversy has surrounded its terminology and surgical management. Recent articles would suggest that surgical opinion is still divided between aggressive radical resection and a more conservative approach. We present an interesting case of a large keratocystic odontogenic tumour shown to have eroded through bony cortices ...
