Bone Scan Introduction
Bone Scan Introduction Mohamed 17,926 Views • 2 years ago

A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.

Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.

Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.

Laparoscopic procedures, EndoGrab (Virtual Ports) Kobi R 13,480 Views • 2 years ago

Virtual Ports, Ltd. (http://www.virtual-ports.com) is a medical device company developing and marketing instruments to improve minimally invasive laparoscopic procedures.
The EndoGrab retraction system reduces the number of ports needed for surgery by eliminating the need for traditional hand held retraction. For the surgeon, this simple solution results in the need for less auxiliary personnel, a decreased overall surgery cost, and more control over the surgery. The EndoGrab also offers added benefit to the patient who will experience less post-operative discomfort and scarring.

The EndoGrab is an internally anchored, hands-free retracting device that is introduced at the start of surgery through a 5mm trocar by means of a proprietary Applier tool. The Surgeon uses the Applier to attach the EndoGrab to both the organ requiring retraction and to the internal abdominal wall, thereby removing the organ from the operative field. The Applier is then removed and the port is free for use by other instruments.

Immunohistochemistry IHC Staining
Immunohistochemistry IHC Staining Doctor 9,885 Views • 2 years ago

Immunohistochemistry or IHC refers to the process of detecting antigens (e.g., proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.[1] IHC takes its name from the roots "immuno," in reference to antibodies used in the procedure, and "histo," meaning tissue (compare to immunocytochemistry). Immunohistochemical staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. Specific molecular markers are characteristic of particular cellular events such as proliferation or cell death (apoptosis). IHC is also widely used in basic research to understand the distribution and localization of biomarkers and differentially expressed proteins in different parts of a biological tissue. Visualising an antibody-antigen interaction can be accomplished in a number of ways. In the most common instance, an antibody is conjugated to an enzyme, such as peroxidase, that can catalyse a colour-producing reaction. Alternatively, the antibody can also be tagged to a fluorophore, such as fluorescein or rhodamine
