In multiple sclerosis, the immune system attacks the protective sheath called myelin, that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves to deteriorate or become damaged.

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.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.

As you can see I access the left implant from the periareolar incisions which I made at the lower portion of the areola. As I entered the capsule and begin to remove the implant I noticed a lot of fluid surrounding the implant. Right away I know this is a rupture and that the mammogram was incorrect. Mammograms are very helpful in detecting cancer but often not ruptures. When implants rupture, it is important to have them replaced as soon as possible to avoid excessive scarring in the breasts. If too much scar tissue has accumulated around the deflated implant, it becomes difficult to create a normal breast shape in the future. Therefor know the signs of a ruptured implant such as, painful to touch, visible asymmetry or loss of integrity to the bag. For more information please visit: www.drlinder.com

Gastroparesis -- literally “paralyzed stomach” -- is a serious condition manifested by delayed emptying of stomach contents into the small intestine after a meal. There is no cure for gastroparesis, but treatment can speed gastric emptying and relieve gastrointestinal symptoms such as nausea and vomiting.

As a curious child, you might remember staring at an older relative's thick stockings at the blue, gnarled veins lying under the skin like bumpy snakes. Known as varicose veins, these blood vessels, which return blood from the legs to the heart, are actually a more superficial system. The real, working venous system for the legs lies deeper, says to Robert A. Weiss, MD, assistant professor of dermatology at the Johns Hopkins School of Medicine in Baltimore. This is good news, because it means that if the surface veins begin to clump up and bulge, they can be removed or destroyed without ruining circulation to the leg. The National Institutes of Health estimates that 60% of all men and women suffer from some form of vein disorder. A quarter of varicose vein sufferers are men, although Weiss notes that it is almost always women who seek help for spider veins.

Multiple Sclerosis Multiple sclerosis (MS) affects the brain and spinal cord. Early MS symptoms include weakness, tingling, numbness, and blurred vision. Other signs are muscle stiffness, thinking problems, and urinary problems. Treatment can relieve MS symptoms and delay disease progression.

Our results in this study of MIPO treated with conventional plates are comparable to the results of the femoral shaft fractures treated with intramedullary nailing. The technique can be used for all femoral shaft fractures. Although the biomechanics of the plate fixation are less stable compared to the intamedullary nail, the mechanical stability is stable enough for bone healing. Healing was rapid, and postoperative care was simplified. The two major complications were malalignment and screw breakage. We recommend using at least three separated screws in each fragment to prevent stress on the screw and screw breakage. Intraoperative limb length, axial alignment, and rotation must be carefully assessed to prevent malalignment. The limitations of our study include lack of a comparison group, retrospective data collection, and no randomisation in outcome evaluation

Sinus infections caused by viruses can use home (over-the-counter, OTC) treatments such as pain and fever medications (acetaminophen [Tylenol]), decongestants, and mucolytics. In addition, some health-care professionals suggest nasal irrigation or a sinus rinse solution to help relieve symptoms of sinus infections, even chronic sinusitis symptoms.
