Preiser disease, or avascular necrosis of the scaphoid, is a rare condition where ischemia and necrosis of the scaphoid bone occurs without previous fracture.It is thought to be caused by repetitive microtrauma or side effects of drugs (e.g., steroids or chemotherapy) in conjunction with existing defective vascular supply to the proximal pole of the scaphoid.
Avascular necrosis(AVN), also called osteonecrosisor bone infarction, is deathof bone tissue due to interruption of the blood supply.[1] Early on, there may be no symptoms.[1] Gradually joint painmay develop, which may limit the person's ability to move.[1] Complications may include collapse of the bone or nearby jointsurface.
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs arise in the smooth muscle pacemaker interstitial cell of Cajal, or similar cells. [ 2 ] They are defined as tumors whose behavior is driven by mutations in the KIT gene (85%), [ 2 ] PDGFRA gene (10%), [ 2 ] or BRAF kinase (rare).

Osteochondrosis is a developmental disease. It usually occurs in an early stage of life. It has personified features as focal chondronecrosis and confinement of growth cartilage due to a failing of endochondral ossification. Fissures can develop from lesions over the top articular cartilage and form a cartilage flap and an osteochondral fragment.
Ménière's disease (MD) is a disease of the inner ear that is characterized by potentially severe and incapacitating episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. [3][4] Typically, only one ear is affected initially, but over time, both ears may become involved. [3] Episodes generally last from 20 minutes ...

Pernicious anemia was a fatal disease before about the year 1920; until the importance of the liver in hematopoiesis was recognized, the treatment of pernicious anemia was unsuccessful and arbitrary. It may have motivated George Whipple, who had a keen interest in liver diseases, to investigate the liver's role in hematopoiesis. Whipple began ...
