Natural painkiller found in human spit. Compound in saliva could be more powerful than morphine. A new painkilling substance has been discovered that is up to six times more potent than morphine when tested in rats — and it's produced naturally by the human body.
It then spreads down the bundle of his and then purkinje fibres to cause ventricular contraction. So when viewing the heart from the front, the direction of depolarisation is 11 o'clock to 5 o'clock. The general direction of depolarisation is known as the cardiac axis.
Pernicious anemia Email this page to a friend Print Facebook Twitter Google+ Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.
This video: Tennis elbow or lateral epicondylitis is a condition in which the outer part of the elbow becomes sore and tender. The forearm muscles and tendons become damaged from overuse — repeating the same strenuous motions again and again.
Skin grafting is a surgical procedure that involves removing the skin from one area of the body and moving it, or transplanting it, to a different area of the body. This surgery may be done if a part of your body has lost its protective covering of skin due to burns, injury, or illness. Skin grafts are performed in a hospital. Most skin grafts are done using general anesthesia, which means you’ll be asleep throughout the procedure and won’t feel any pain.
The heart, blood vessels, and blood are the parts that make up the circulatory system, which is defined as a closed system of blood vessels for the transport of gasses and nutrients. The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.
This is the biggest known operation ever.The Whipple procedure(pancreatoduodenectomy) is the most common operation performed for pancreatic cancer and may be used to treat other cancers such as small bowel cancer. Surgeons remove the head of the pancreas, most of the duodenum (a part of the small intestine), a portion of the bile duct and sometimes a portion of the stomach. After the pancreatoduodenectomy, the surgeon reconstructs the digestive tract. At Mayo Clinic, surgeons perform more than 100 Whipple procedures annually. Patients leave the hospital in an average of 14 days.
Knee replacement surgery advances are improving patients' experiences and outcomes. Knee surgery -- or even partial knee replacement -- is often the solution for advanced knee arthritis. Today you can regain significant mobility and flexibility after knee replacement thanks to advances in orthopedic surgery technology, materials and techniques. Knee replacement recovery times also have improved. This knee replacement surgery video covers what you can expect out of these knee joint replacement advances. Knee replacement surgery has been around for more than 30 years and is an incredibly successful operation. In the past the past, when a person had bad arthritis of the knee, they were pretty much out of luck other than taking aspirin. They'd be debilitated and limited in their activities. So, when a person has pain, stiffness, and their life is becoming restricted by that, that's when it's time to consider knee replacement. We always do non-surgical treatment first. When that doesn't work anymore, then it's time to consider knee replacement. About 500,000 a year are done, and most patients who have gone through this basically say that they wish they had done it sooner.
Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.
poor posture (postural kyphosis) – slouching, leaning back in chairs and carrying heavy bags can stretch supporting muscles and ligaments, which can increase spinal curvature. abnormally shaped vertebrae (Scheuermann's kyphosis) – if the vertebrae don't develop properly, they can end up being out of position.
Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.
Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease characterized by the classic triad of persistent high spiking fevers, joint pain, and a distinctive salmon-colored bumpy rash. The disease is considered a diagnosis of exclusion.
