Magnetic Resonance Imaging (MRI) "sees" inside the body by mapping the position of water molecules, which exist at different densities in different types of tissue. Watch the video above for a sample of some impressive MRI images of the human body in action.
High-Cervical Nerves (C1 – C4) Most severe of the spinal cord injury levels Paralysis in arms, hands, trunk and legs Patient may not be able to breathe on his or her own, cough, or control bowel or bladder movements. Ability to speak is sometimes impaired or reduced. When all four limbs are affected, this is called tetraplegia or quadriplegia. Requires complete assistance with activities of daily living, such as eating, dressing, bathing, and getting in or out of bed May be able to use powered wheelchairs with special controls to move around on their own Will not be able to drive a car on their own Requires 24-hour-a-day personal care
Our nervous system is involved in everything our body does, from maintaining our breath to controlling our muscles. Our nerves are vital to all we do; therefore, nerve pain and damage can heavily influence our quality of life. In Discovery News' latest video, "Why Can't We Reverse Nerve Damage?" host Lissette Padilla explains the central nervous system (CNS) has certain proteins that inhibit cell regeneration, because each cell in the nervous system has a unique function on the pathway, like a circuit, and can't be replaced.
Hereditary hemochromatosis (he-moe-kroe-muh-TOE-sis) causes your body to absorb too much iron from the food you eat. Excess iron is stored in your organs, especially your liver, heart and pancreas. Too much iron can lead to life-threatening conditions, such as liver disease, heart problems and diabetes.
The lateral approach is used for insertion of fixation devices after closed reduction of a proximal femoral fracture. Reduction of a displaced fracture is usually done with a fracture table, or alternatively a large distractor spanning the hip joint. After satisfactory reduction is confirmed by image intensifier, the lateral approach can be used for insertion of a sliding hip screw or multiple screws. The approach provides limited access to the lateral surface of the femur sufficient for hardware placement. The incision can be extended proximally to accommodate a trochanteric stabilizing plate (TSP), or even anteriorly so that it becomes an anterolateral approach with direct, although limited, access to the femoral neck.
A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.
Removing a hump from the bridge is one of the most common things people want addressed during their rhinoplasty. Nasal humps can range widely in size. Perhaps you just have a small bump that you'd like refined? Or maybe you have more of a Roman Nose with a more dominating, distracting large hump? No matter if your nose falls on one of these extremes or somewhere in between rhinoplasty surgery can be used to reshape your nose. For anyone considering having a rhinoplasty to reduce a hump on their bridge there are several things to consider before having surgery.
