what is osteo fibrosis?

Answer 1

os·te·o·fi·bro·sis (ŏs'tē-ō-fī-brō'sĭs)
n. Fibrosis of bone, mainly involving bone marrow.
Osteofibrosis:
Osteofibrosis is the replacement of bone with fibrous tissue. This can happen in small areas as the result of local inflammatory reactions or it may be generalized. It may be associated with liver dysfunction and kidney disease, the latter resulting in failure to discard urates which build up in the tissues, causing gout. Another important effect is the loss of calcium by excretion and the retention of phosphorus Since calcium is not conserved by the kidney, more of it is mobilized from the bone in order to maintain adequate blood levels, without which severe nervous signs would result. In the process, an excess of phosphorus accumulates in the body tissues and bone becomes replaced by fibrous or scar tissue. There is consequently a softening of all layers of bone, which is most noticeable in the pelvis and limbs and the facial bones supporting the beak. The advanced and clinically apparent disease is seldom recognized, however, but the signs of renal disease may be, and it is this which is responsible for death. There is little hope of cure or even of easing the clinical signs for any length of time. A simple bacterial infection is seldom responsible for the renal disease and usually the cause cannot be found.

Other osteodystrophies are poorly understood in birds. A skeletal abnormality which is characterized by thin walled and soft long bones, which buckle or fracture without external violence of any sort, is sometimes seen in parrots, macaws and other large psittacines. It is probably a dietary deficiency of a similar kind to osteomalacia. It is referred to as osteoporosis (porous bone) because calcium salts are sparsely scattered throughout the osteoid tissues, leaving un-mineralized spaces containing soft tissue. A skeletal deformity associated with disturbances in estrogen production is known as hyperostosis.

Answer 2

People with Cystic Fibrosis can pass bacterium like cepacia, pseudomonas, MRSA, etc... to each other. I have a seven year old daughter with CF so it's always a huge concern when we are in hospital.... trying to avoid other CFers. It's really kind of sad as who could understand what a CFer goes through more than another CFer? They used to have ''CF camps'' until they realized they were picking things up off each other. Now in hospital, they are all separated from each other.
