Chronic paroxysmal hemicrania Chronic paroxysmal hemicrania Chronic paroxysmal hemicrania (CPH), also known as Sjaastad syndrome, is a severe debilitating unilateral headache usually affecting the area around the eye. It normally consists of multiple severe, yet short, headache attacks affecting only one side of the cranium. It is more commonly diagnosed in women than in men, but, unlike a migraine, has no neurological symptoms associated with it. CPH headaches are treated through the use of non-steroidal anti-inflammatory drugs, with indomethacin found to be usually effective in eliminating symptoms. Paroxysmal hemicrania is classified by the frequency and duration of attacks experienced by patients. Episodic paroxysmal
Common firecrest Latin "regulus", a diminutive of "rex", "a king", and refer to the characteristic orange or yellow crests of adult kinglets. The common firecrest was first formally described by Dutch zoologist Coenraad Jacob Temminck in 1820 as "Sylvia ignicapilla"; the relatively late identification of this common European bird arose from a perception that it was just a variety of the goldcrest. The species name is derived from Latin "ignis" "fire" and "capillus" "hair". The binomial is frequently given as "R. ignicapillus" due to a misunderstanding of Latin grammar. There are two widely recognised subspecies of common firecrest, nominate "R. i. ignicapilla"
