Abstract:
We report a 40-year-old man who presented with multiple bone pseudofractures after about 20 years from the onset of Wilson's disease (WD). At age 36, he first noticed pain in his left shoulder. At age 39, he had multiple chest pain. On neurologic examinations, dysarthria and dysphagia due to pseudobulbar palsy, rigidity and tremor on right upper lim were observed. WD was confirmed because of low levels of plasma cupper and ceruloplasmin in addition to ATP7B gene mutation. The chest X-ray revealed multiple fractures of the several ribs. We diagnosed osteomalacia due to Fanconi's syndrome because of hypophosphatemia and the impairment of renal tubules for WD. After administration of vitamin D, there happened no new bone pseudofractures. Although bone pseudofractures accompanied by Wilson's disease generally happen in childhood, we should be aware of this symptom even in adulthood.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Nephrotic Syndrome I : Introduction
Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
