Hope I'm not jumping the gun, and everything continues to improve, but...
Still don't know the full facts yet because no one's been in a fit state to give them. However the story so far is that my grown up nephew (in Australia), went to the doctors a couple of weeks ago with suspected tonsillitis and was immediately rushed to hospital - turns out he had some sort of sepsis and necrotizing (flesh eating) bug or something.
In less than a day he was already critically ill, they had to put him in a coma because his organs were failing, and they almost immediately removed tissue from his (left?) leg, and opened up all his other limbs to check the spread of the infection. By about day two/three they were saying he had less than 10% chance of survival, and if he did, then it might only be because they'd amputated his limbs to stop the diseasing spreading.
Long story short; somehow or other he/they managed to fight off the disease, nothing was amputated, his organs are improving (still on dialysis though), they finally managed to bring him round (not yet properly with it), and the prognosis seems to be getting better every day - except he now has pneumonia.
Fingers crossed he keeps up the recovery, it was extremely touch and go for a while, but most of the news is hopefully going to remain positive - hope so for the sake of his wife and two small children.
My sister/his mum asked everyone to pray for him, I abstained because I'm not into that sort of stuff, but I'd never go out of my way to tell her. If she wants to put everything down to the power of pray, that's perfectly OK with me, it's helped her get through a very difficult time.
Was this the good ending we are all hoping? Only just seen this post.
