In 1958, Anthony R. Curreri, Fred J. Ansfield, Forde A. McIver, Harry A. Waisman, and Charles Heidelberger reported the first clinical findings of 5-FUs activity in cancer in humans. Natural analogues
In 2003, scientists isolated 5-fluorouracil derivatives, closely related compounds, from the marine sponge, Phakellia fusca collected around the Yongxing Island of the Xisha Islands in the South China Sea. This is significant because fluorine-containing organic compounds are rare in nature, and  also because manmade anticancer drugs are not frequently found to have analogues in nature.

Benign paroxysmal vertigo of childhood is an uncommon neurological disorder which presents with recurrent episodes of dizziness. The presentation is usually between the ages of 2 years and 7 years of age and is characterised by short episodes of vertigo of sudden onset when the child appears distressed and unwell. The child may cling to something or someone for support. The episode lasts only minutes and resolves suddenly and completely. It is a self-limiting condition and usually resolves after about eighteen months, although many go on to experience migrainous vertigo (or vestibular migraine) when older.Benign paroxysmal vertigo of childhood is a migrainous phenomenon with more than 50% of those affected having a family history of migraines affecting a first-degree relative. It has no relationship to benign paroxysmal positional vertigo which is a different condition entirely. == References ==
