Hi Cath
I have written some notes on this problem before, the problem being is that on this site there isn't a seperate heading for ONJ or bisphosphonates with all messages on. I cannot find my previous notes anywhere now. I can type in a variety of things and still I can't find them. If this was under a seperate heading like breast colon ovarian etc it would make things easier.
I have had ONJ for several years. I suspected it and diagnosed it myself in 2002, pressed for more info in 2003 told to remain on Zometa. then in 2004 it was finally confirmed and off zometa. I have spent a lot of time researching this and it seems that until a case in brought to the companies it is unlikely to get much media attention.
Still I find doctors and dental surgeons alike know nothing about this condition, so I have found my own way reading through the maze of little info. One site you can look up is Professor Salvatore Ruggiero at LOng Island Jewish Medical centre, He and Marx et all warned the drugs companies 99/2000 that they were seeing this condition and it was they who pressed the FDA to ensure the drug companies listed this condition in their side effects.
Still 8 years on little is known how it might be caused, no evidence links the Bisphosphonate induced Osteonecrosis of the jawbone to Biphosphonates or any one of them in particular. No case to my knowledge has yet been tried in the courts.
My knowledge so far is
Zometa is more potent than any other Bisphosphonate
BISONJ can be seen after taking BIS
ONJ is difficult to diagnose.
Onj causes much suffereing to those affected.
Numbers affected are presently misleading as it is not diagnosed accurately, if at all.
There appears to be a link with the strength and duration of time the drug is taken.
All advice is to leave well alone.
No surgery should be carried out to correct dying jawbones. it has failed to heal.
Extrusion of jawbone through the gums can be debrided but no invasive procedures are recommended as healing is delayed considerably.
All dental work should be completed and healed before taking the drug.
Hot salty water rinses are as effective at reducing the risk of infection as any prescribed mouthwashes in my own experience (5 times daily)
It has been proposed that only myleoma patients are affected. if you have had chemotherapy, if you have had steroids, had cancer, only in cases where BIS is given IV. In the cases I have heard about, this doesn't seem to be the case. I had proposed to start an ONJ UK website but I have stage IV cancer and have been too ill to follow through with this.
National dental associations are now getting to grips with this and if you look up various countries' sites you will gather more info, more than oncology sites.
I hope this helps
