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.

Central Line - Subclavian infraclavicular approach
Central Line - Subclavian infraclavicular approach samer kareem 12,707 Views • 2 years ago

First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.

Wolff-Parkinson-White Syndrome
Wolff-Parkinson-White Syndrome samer kareem 1,814 Views • 2 years ago

Wolff-Parkinson-White (WPW) syndrome, an extra electrical pathway between your heart's upper and lower chambers causes a rapid heartbeat. The extra pathway is present at birth and fairly rare. The episodes of fast heartbeats usually aren't life-threatening, but serious heart problems can occur. Treatment can stop or prevent episodes of fast heartbeats. A catheter-based procedure (ablation) can permanently correct the heart rhythm problems. Most people with an extra electrical pathway experience no fast heartbeat. This condition, called Wolff-Parkinson-White pattern, is discovered only by chance during a heart exam. Although WPW pattern is often harmless, doctors might recommend further evaluation before children with WPW pattern participate in high-intensity sports.

Shoulder
Shoulder samer kareem 7,194 Views • 2 years ago

The shoulder is one of the largest and most complex joints in the body. The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula. The clavicle (collarbone) meets the acromion in the acromioclavicular joint. The coracoid process is a hook-like bony projection from the scapula.

Dental Cavity

If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.

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.
