Bone Scan Introduction
Bone Scan Introduction Mohamed 17,962 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.

An ectopic pregnancy results when a fertilized egg implants outside the uterus. Unfortunately, there's no way to transplant an ectopic pregnancy into your uterus, so ending the pregnancy is the only option. About 2 percent of pregnancies are ectopic. Because ectopic pregnancy is potentially dangerous for you, it's important to recognize the early signs and get treatment as soon as possible.

Doctors give soldier New Ear after growing it in her arm
Doctors give soldier New Ear after growing it in her arm Mohamed Ibrahim 1,229 Views • 2 years ago

Shamika Burrage survived a near-fatal car accident two years ago, but not without losing something pretty important: her left ear. Now, thanks to a novel procedure performed at an Army medical center in Texas, Burrage is getting that ear back in a most unusual way. Plastic surgeons harvested cartilage from Burrage's ribs to create a new ear and then grew it under the skin of her forearm. Then the doctors at William Beaumont Army Medical Center in El Paso successfully transplanted the ear from her arm to her head. The technique -- a first time in the Army -- is called prelaminated forearm free flap, said Lt. Col. Owen Johnson III, chief of plastic and reconstructive surgery at William Beaumont Army Medical Center. Some of the big advantages of it is that it reduced the chance of more scarring around Burrage's ear. Also, growing the ear under the skin of her forearm allows new blood vessels to form. "(The ear) will have fresh arteries, fresh veins and even a fresh nerve so she'll be able to feel it," Johnson said on the US Army's website. Burrage, a 21-year-old private, still has to endure two more surgeries, but she's feeling more optimistic about the future than ever in the years since her accident. "It's been a long process for everything, but I'm back," said Burrage.

Parasite Cleanse
Parasite Cleanse samer kareem 2,942 Views • 2 years ago

Do you need to do a parasite cleanse? Probably... I hear from so many people suffering from symptoms of parasites - severe bloating, cramps, constipation, diarrhoea. A big problem in getting to the bottom of this (pun intended) is that the mainstream medical system really doesn’t have a way to detect, or even find most forms of parasites. They give you drugs for the symptoms, but essentially the parasites aren’t removed during that process.
