Osteonecrosis of the hip, a condition in which the bone tissue in the hip dies, affects mainly young, active patients. Its origin is unknown, making it more difficult to treat. The authors of this study undertook a research of the literature to find previously completed studies that investigated the causes and treatments for osteonecrosis of the hip. The researchers reviewed the article for etiology (origin of the disease), pathophysiology (changes associated with the injury), evaluations, and both surgical and non-surgical treatments. The researchers found that although no distinct cause for osteonecrosis of the hip has been found, some factors appeared to be involved in the development. Among those were consumption of alcohol, high doses of corticosteroids, and abnormal clotting of the blood ( coagulation , as well as some genetic factors. For evaluations, physicians have been relying on magnetic resonance imaging (MRI), which has a 99 percent accuracy rate in detecting osteonecrosis o...
Pathophysiology is functional changes associated with or resulting from disease or injury and the study of those changes. When related to Migraine attacks, the pathophysiology of a Migraine attack would mean the changes in how the brain and central nervous stem function when a Migraine is triggered and during the Migraine attack. We could discuss the pathophysiology of how the triggers themselves work -- what changes occur when we encounter a trigger. We could discuss the pathophysiology of a Migraine attack -- what happens to the blood vessels, the nerves and tissues surrounding the blood vessels, the levels of neurotransmitters such as serotonin and norepinephrine. All of these discussions would be about the pathophysiology of Migraine, something that is still not fully understood. Researchers are making advances, however. The most recent article we published about Migraine research that was related to pathophysiology is Why Hangovers May Be Worse for Migraine Suffer...
