Paget's disease of bone (PDB) is a common condition with a strong genetic component that is characterized by focal increases in bone turnover, leading to bone deformity, pathological fractures, and various other complications. Several rare disorders have also been described that show phenotypic overlap with PDB Paget disease of bone (PDB), also known historically as osteitis deformans, is a focal disorder of bone metabolism that occurs in the aging skeleton; it is characterized by an accelerated rate of bone remodeling, resulting in overgrowth of bone at single (monostotic PDB) or multiple (polyostotic PDB) sites and impaired integrity of affected bone The cause of Paget's disease of bone is unknown. Scientists suspect a combination of environmental and genetic factors contribute to the disease. Several genes appear to be linked to getting the disease. Some scientists believe Paget's disease of bone is related to a viral infection in your bone cells, but this theory is controversial. Risk factor
Paget's disease of the bone is a skeletal disorder which results in increased and disorganized bone remodeling, leading to dense but fragile and expanding bones. The identified genetic causes of Paget's disease of bone only explain why bone is destroyed, but not why the bone formed in its place is abnormal Paget's disease of bone (commonly known as Paget's disease or, historically, osteitis deformans) is a condition involving cellular remodeling and deformity of one or more bones. The affected bones show signs of dysregulated bone remodeling at the microscopic level, specifically excessive bone breakdown and subsequent disorganized new bone formation. [1 Abstract.

Keywords: Paget's disease of bone, bisphosphonates, osteoclasts Introduction Paget's disease of bone (PDB), which is also known as osteitis deformans, was first described by Sir James Paget more than 130 years ago [Paget, 1877]. Paget's disease is a common focal skeletal disorder that may involve a single bone (monostotic) or multiple bones (polyos Paget's disease of bone is a chronic disease of the skeleton. In healthy bone, a process called remodeling removes old pieces of bone and replaces them with new, fresh bone. Paget's disease causes this process to shift out of balance, resulting in new bone that is abnormally shaped, weak, and brittle

Paget's disease is a disorder of bone that manifests in one or several bones and is initiated by osteoclast-induced osteolytic lesions. In addition to a genetic cause, environmental factors. Paget's Disease is an idiopathic condition of abnormal bone remodeling with normal bone being replaced through an active interplay between excessive bone resorption and abnormal new bone formation. The condition typically present in patients age > 40 with asymptomatic lesions discovered incidentally on radiographs
Paget disease of bone (PDB) mainly affects the elderly, being rare before the age of 55 years. Radiographic surveys suggest that it affects approximately 2-4% of Australians over 55 years of age, making it the most common metabolic bone disorder after osteoporosis. 1-3. The disease has a peculiar geographical distribution, with the highest reported prevalence in northwest England, and is. INTRODUCTION. P aget's disease of bone (PDB) is a chronic focal bone remodeling disorder that typically results in enlarged and deformed bones in one or more regions of the skeleton. 1, 2 This disease is most often asymptomatic, but can cause a variety of medical complications resulting in considerable morbidity and reduced quality of life. 3 PDB is most common in white people of European. Etiology is unknown at present; however, several etiological factors have been suggested. Genetics: familial clustering suggests that Paget disease may have an autosomal dominant pattern of inheritance with variable penetrance. Siris ES, Ottman R, Flaster E, et al. Familial aggregation of Paget's disease of bone
Paget disease is a localized disorder that may be monostotic (affecting only one bone) or polyostotic (affecting 2 or more bones). Monostotic disease accounts for 10-35% of cases. Paget disease has a predilection for the axial skeleton. The condition commonly affects the pelvis and spine, particularly the lumbar spine, with a frequency of 30-75% Paget's disease of bone is a chronic condition that causes abnormal enlargement and weakening of bones. Any part of the skeleton can be affected, but the most common sites include the skull, spine, pelvis, thigh bone, shin and the bone of the upper arm. Paget's disease of bone tends to affect people over the age of 50 Bone pain is characteristically present at rest, at night, and with use of the affected bone. 4 Deformities that occur in the skull, facial bones, and extremities are more easily identifiable. 1 Incomplete fissure fractures and complete fractures, which are typically transverse breaks, can be a major complication of Paget's disease. 2. Pathogenesis increased multinucleated osteoclastic and osteoblastic activity leads to a high bone remodeling rate resulting in a bnormal bone architecture (lytic and blastic lesions) Prognosis expansion of untreated Paget lesions; Presentation: Symptoms . usually asymptomatic; bone and/or joint pain; bone deformity bowing deformity; hearing los PAGET'S DISEASE OF BONE (Osteitis deformans) Characterized by abnormal resorption and deposition of bone, resulting in distortion and weakening of bone. ETIOLOGY: - Unknown, but predisposing factors could be - inflammatory, genetic, endocrine factors or a slow virus infection, autoimmune, connective tissue or vascular disorder
Paget Disease of the bone, also known as Osteitis Deformans, is a disorder caused by osteoclast hyperactivity, yielding focal areas of excessive bone remodeling that over time heal in a haphazard, structurally weak arrangement prone to deformation and fracture. Onset is almost always in the elderly with a slight predilection for men Your body constantly builds new bone to replace the old. But with Paget's disease, this happens too fast and gives your bones an odd shape. They may be bent, weak, brittle, soft, or too big . *Reproduced from Ralston, S.

. Examples of metabolic bone diseases include osteoporosis, rickets, osteomalacia, osteogenesis imperfecta, marble bone disease (osteopetrosis), Paget disease of bone, and fibrous dysplasia. I Paget's disease of bone (also known as osteitis deformans) is a nonmalignant disease involving accel- erated bone resorption followed by deposition of dense, chaotic, and ineffectively. Paget's Disease as stated is a chronic pathological condition of the bones in which there is a disorder of the normal process of bone remodeling. Paget's Disease affects the skeletal bones. Studies estimate that about 1% of population in the United States have Paget's Disease Paget's disease of bone affects the structure of parts of one or more bones. In most cases it causes no symptoms and does not need treatment. Symptoms develop in some cases and pain in the affected part of bone is the most common symptom. Affected bones are weaker than normal and may become deformed and may break (fracture) more easily than normal
Paget's disease presents clinically in a variety of ways ( Box 1 ), depending in part on the bones affected. Most commonly, the disease involves the pelvis, lumbosacral spine, skull, femur or tibia, but any bone may be affected, and the disease may be localised to one or a few bones or widespread throughout the skeleton Paget's disease is a rare disorder of the bone affecting the rate of formation and destruction of various bones of the skeleton. It is common in the elderly and those from European descent . Although the disease can affect any bone, the most common sites are the spine, skull, pelvis, and weight-bearing leg bones Paget's disease of bone is a condition involving cellular remodeling and deformity of one or more bones. The affected bones show signs of dysregulated bone remodeling at the microscopic level, specifically excessive bone breakdown and disorganized new bone formation. Genetic factors have a fundamental role in the pathogenesis of PDB and are. Paget's disease (PD) is a focal disorder of bone remodelling that occurs commonly in older people. In this article, we review clinical aspects of PD with an emphasis on recent findings. The epidemiology of PD appears to be changing rapidly, with several groups in different parts of the world reporting a marked reduction in the prevalence and incidence of PD, as well as in the severity of.
The Paget's Association, also known as the National Association for the Relief of Paget's Disease, is the only UK charity to focus solely on Paget's Disease of Bone. The Association acts as a resource for those with the condition, the public and health professionals, offering high-quality information and support services Paget's disease, or osteitis deformans, is a chronic metabolic disorder characterized by increased bone turnover and breakdown secondary to excessive and disorganized osteoclastic and osteoblastic activity ( Fig. 48.1 ). The precise etiology is still unclear. The excessive breakdown of bone is followed by the formation of weak and abnormal bone

Seton M, Moses AM, Bode RK, Schwartz C. Paget's disease of bone: the skeletal distribution, complications and quality of life as perceived by patients In bone affected by Paget's disease, the osteoclasts (the cells responsible for bone resorption) are larger and more active than normal, and consequently resorption of bone is increased. Because the process of bone resorption and bone formation are tightly coupled, there is a subsequent increase in the rate of bone formation Paget's disease of bone (PDB) is a focal, chronic skeletal disorder characterized by enhanced resorption of bone as a result of overactivity of osteoclasts followed by the formation of bone by osteoblasts. This process results in a disorganized, mosaic pattern of woven and lamellar bone that is associated with increased vascularity, marrow.

Epub 2008 Nov 19. PMID 19064007 : Pathogenesis of Paget disease of bone. Ralston SH, Layfield R Paget's disease can occur in any bone, but it is most common in the spine, pelvis, femur, sacrum, and skull, in order of descending frequency. Osteoporosis may occur in multiple bones. Paget's disease does not spread from bone to bone, but becomes progressively worse as it extends from a single site
To diagnose Paget's disease of bone, a doctor will likely perform a physical examination and review your symptoms. It's likely that blood tests and X-rays also will be conducted to confirm the diagnosis. One blood test result that can point towards Paget's disease of bone is a raised level of an enzyme called alkaline phosphatase Paget's disease of bone can sometimes lead to further problems. Broken bones. Bones affected by Paget's disease of bone tend to be more fragile than normal bone and are more likely to break (fracture) - even after a relatively minor injury. Signs of a fracture include: sudden, severe pain ; swelling or tenderness around the injured are Paget's disease of bone is a chronic disorder that can result in enlarged and misshapen bones. The excessive breakdown and formation of bone tissue cause the affected bone to weaken, resulting in pain, misshapen bones, fractures, and other bone and joint problems, including osteoarthritis A bone scan is a test that helps identify which bones have been affected by Paget's disease. The procedure is also a useful way to determine the extent and activity of the disease. In a bone scan, a safe amount of a radioactive substance is injected into the person's vein Pathophysiology of Paget's Disease of Bone Study Purpose Paget's disease of the bone is a skeletal disorder which results in increased and disorganized bone remodeling, leading to dense but fragile and expanding bones. The identified genetic causes of Paget's disease of bone only explain why bone is destroyed, but not why the bone formed in its.
Studies of the etiology of Paget's disease have focused separately on the viral and genetic components of the disease. In this issue of Cell Metabolism, Kurihara et al. (2011) join these components, reporting that sequestosome 1 mutation in patients and mice activates osteoclasts, while measles virus induces the phenotype of Paget's disease Paget's disease of the nipple, also known as Paget's disease of the breast, is a rare type of breast cancer. The term Paget's disease of the nipple is used to distinguish the condition from Paget's disease of the bone, which occurs when the normal cycle of bone growth is disrupted, leading to the bones becoming weak and deformed Differential diagnosis and pathogenesis. J. T. Anderson, L. P Of fourteen patients with Paget's disease for whom adequate roentgenograms and pathological material were available, 6 had lesions showing significant or predominant osteolysis. An osteolytic lesion in a patient without other bone disease may be due to Paget's disease, while.
ABSTRACT. Paget's disease of bone (PDB) is a chronic progressive disorder of bone metabolism that may go undetected for many years, and endocrinologists should be alert to its clinical signs and promptly diagnose and treat PDB before it results in irreversible complications, such as deformity, fracture or neurological sequelae In summary, Paget's disease of bone is a disease characterized by large and improperly shaped bones that lead to pain, fractures, and arthritis. It occurs as a result of an improper balance.
