She also experiences very little anxiety and fear, and may have enhanced wound healing due to the mutation, which the researchers say could help guide new treatments for a range of conditions, they report in the British Journal of Anaesthesia.
At age 65, the woman sought treatment for an issue with her hip, which turned out to involve severe joint degeneration despite her experiencing no pain. At age 66, she underwent surgery on her hand, which is normally very painful, and yet she reported no pain after the surgery. Her pain insensitivity was diagnosed by Dr Devjit Srivastava, Consultant in Anaesthesia and Pain Medicine at an NHS hospital in the north of Scotland and co-lead author of the paper.
The woman tells researchers she has never needed painkillers after surgery such as dental procedures.
Nije prvi put da se otkriju ovakvi slucajevi, ali ono sto je zanimljivo sto je ovog puta otkriven konkretan gen, FAAH-OUT, koji je inace ranije smatran za 'junk' gen (nefunkcionalan). Ovaj gen regulise endokanabioidnu signalizaciju koja ucestvuje u percepciji bola, raspolozenja i formiranju memorija.
Naravno, zivot bez bola nije bas bezopasan, tako da doticna osoba saznaje da je opekla ruku tek kada pocne da mirise izgorelu kozu.
Ko zna, mozda neki buduci lekovi koji direktno regulisu ekspresiju ovog gena budu daleko bezbedniji analgetici od trenutno dostupnih.
