One can find titanium in neurosurgery, bone conduction hearing aids, false eye implants, spinal fusion cages, pacemakers, toe implants, and shoulder/elbow/hip/knee replacements along with many more. The main reason why titanium is often used in the body is due to titanium's biocompatibility and, with surface modifications, bioactive surface.
If the tumors become cancerous, some cases can be life-threatening. The disorder affects 1 in 30,000 people. Although many different types of hormone-producing tumors are associated with multiple endocrine neoplasia, tumors of the parathyroid gland, pituitary gland, and pancreas are most frequent in multiple endocrine neoplasia type 1.
Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Melson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat extreme slackness. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Central nervous system (CNS) disorders or conditions may cause SIADH in 9% of cases, this includes subarachnoid hemorrhage (56% of CNS causes), pituitary surgery (35% of CNS causes), brain cancer, infections, stroke and head trauma. [2] No cause of inappropriate antidiuresis is initially found in 17–60% of cases. [2]
The tumor histopathology is jumbled small and large cells. The tissue of this tumor contains many different types of cells including the rhabdoid cells, large spindled cells, epithelial and mesenchymal cells, and areas resembling primitive neuroectodermal tumor (PNET). As much as 70% of the tumor may be made up of PNET-like cells.
An endocrinologist is only involved in preparation for an endoscopic endonasal surgery, if the tumor is located on the pituitary gland. The tumor is first treated pharmacologically in two ways: controlling the levels of hormones that the pituitary gland secretes and reducing the size of the tumor. If this approach does not work, the patient is ...
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
