Magnetic resonance imaging (MRI) can be an important tool in the diagnosis of multiple sclerosis (MS). MRI can also be used to monitor the progression of the disease in people living with MS. How does it work? MRI uses very strong magnets, radio signals, and computer software to take 3-dimensional pictures of the inside of the body. Will I need contrast material? Maybe. Contrast material is a substance that temporarily changes the way imaging tools interact with the body. They are often used to visualize certain types of MS disease activity on the MRI. If your doctor thinks your scan requires this contrast material, you may get an injection before you get in the MRI machine. How long will it take? The time may vary based on the type of MRI. Be sure to discuss with your doctor in advance so he or she can provide you with exact timing. But don’t worry, you won’t have to stay still the whole time. The technician will let you know when they’re starting a new image.

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

The syndrome of inappropriate antidiuretic hormone (ADH) secretion (SIADH) is defined by the hyponatremia and hypo-osmolality resulting from inappropriate, continued secretion or action of the hormone despite normal or increased plasma volume, which results in impaired water excretion.

Possible complications include: Cardiovascular disease. ... Nerve damage (neuropathy). ... Kidney damage (nephropathy). ... Eye damage (retinopathy). ... Foot damage. ... Skin conditions. ... Hearing impairment. ... Alzheimer's disease.

-Korsakoff's syndrome is a common and preventable sequel of Wernicke's encephalopathy. Thiamine, if given during the stage of Wernicke's encephalopathy, can prevent the onset of Korsakoff's psychosis. The administration of glucose prior to thiamine can precipitate Korsakoff's syndrome, as seen in this case. In such patients, brain MRI frequently shows abnormal enhancement of the mammillary bodies & thallamus

-Almost all the cases of occupational transmission of HIV have been due to transmission via exposure to blood and certain body fluids. The body fluids wherein standard precautions have been recommended include semen, vaginal secretions, and any other body fluid containing visible blood. Other standard precautions, according to the Center for Disease Control and Prevention (CDC), also apply to cerebrospinal, peritoneal, pleural, pericardia!, synovial fluid, or any other tissue, even though the epidemiologic data regarding the risk of HIV transmission from these fluids is insufficient. Standard precautions do not apply to urine, sweat, tears, sputum, vomitus, and nasal secretions or feces, as long as there is no gross visible blood. The occupational transmission of HIV has never been documented from the above sources.

Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis. Majority of the cases involving the lower extremities are due to a traumatic event, most commonly tibial fractures. Other causes include a crush injury or other long bone fractures in a motor vehicle accident, a tight cast or dressing after trauma, and drug overdose.

A nephron (from Greek νεφρός (nephros) meaning "kidney") is the basic structural and functional unit of the kidney.

The most popular form of overbite correction is orthodontic treatment. Your dentist will fix the overbite with the help of rubber bands and dental braces to pull the upper teeth back. Tooth extraction may be suggested if overcrowding complicates the overbite so as to provide room for your front teeth. In extreme conditions, overbite surgery may be needed to place your jaw backwards or forwards. Furthermore, if severe overbite is not corrected during adulthood, the teeth may continue to shift and trigger dental issues such as gum disease.
