Polyarteritis nodosa Email this page to a friend Email this page to a friend Facebook Twitter Google+ Polyarteritis nodosa is a serious blood vessel disease. The small and medium-sized arteries become swollen and damaged. Causes Arteries are the blood vessels that carry oxygen-rich blood to organs and tissues. The cause of polyarteritis nodosa is unknown. The condition occurs when certain immune cells attack the affected arteries. More adults than children get this disease. The tissues that are fed by the affected arteries do not get the oxygen and nourishment they need. Damage occurs as a result. People with active hepatitis B or hepatitis C may develop this disease.

The needle should pass through the tissue at a perpendiculaPlace the tips of the left-hand forceps on the underside of the tissue at the point where the needle will enter, and gently push the edge upward. With the right hand, bring the needle into contact with the tissue, and press downward. These movements create eversion. Pass the needle through. Do not grab the tissue with your left hand forceps since it will damage the intima. If needed, you can pick up adventitia or a nearby suture to help with exposure and eversion. r.The needle must pass through the other side at a perpendicular, too. Bring the tip of the needle to the place where you intend to bring it out on the other side. Put the tip of your left-hand forceps on the upper surface of the tissue at the intended exit point. Press down with the left-hand forceps and push up with the needle to give you the correct eversion. The width of the bite should be about three times the thickness of the needle. The bites on both sides must be equal, and the needle should cross exactly in a straight line (not diagonally). Pull the needle through the tissue following the curve of the needle

Major signs and symptoms include enlargement of the liver and spleen (hepatosplenomegaly), a low number of red blood cells (anemia), easy bruising caused by a decrease in blood platelets (thrombocytopenia), lung disease, and bone abnormalities such as bone pain, fractures, and arthritis.

Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.

Research from Mayo Clinic finds that half of elderly patients who start dialysis after age 75 will die within one year.

Lead study author and a health care delivery scholar with the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery, Dr. Bjorg Thorsteinsdottir says many elderly patients and their families feel that they have no choice but to start dialysis, with several expressing regret from having initiated therapy.

The findings were presented at the American Society of Nephrology's Kidney Week 2013 in Atlanta.

procedure is usually done in the hospital or outpatient surgical center under general anesthesia (while you are asleep and pain-free). The procedure is performed in the following way: The surgeon makes a small cut (incision) below the belly button (navel). A needle or tube is inserted into the incision. Carbon dioxide gas is passed into the abdomen through the needle or tube. The gas helps expand the area, giving the surgeon more room to work, and helping the surgeon see the organs more clearly. A tube is placed through the cut in your abdomen. A tiny video camera (laparoscope) goes through this tube and is used to see the inside of your pelvis and abdomen. More small cuts may be made if other instruments are needed to get a better view of certain organs. If you are having gynecologic laparoscopy, dye may be injected into your cervix area so the surgeon can view your fallopian tubes. After the exam, the gas, laparoscope, and instruments are removed, and the cuts are closed. You will have bandages over those areas.

Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance. Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function.

Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. You may have sleep apnea if you snore loudly, and you feel tired even after a full night's sleep. The main types of sleep apnea are: Obstructive sleep apnea, the more common form that occurs when throat muscles relax. Central sleep apnea, which occurs when your brain doesn't send proper signals to the muscles that control breathing. Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, occurs when someone has both obstructive sleep apnea and central sleep apnea. If you think you might have any form of sleep apnea, see your doctor. Treatment can ease your symptoms and may help prevent heart problems and other complications.

Surgery to replace an aortic valve is done for aortic valve stenosis and aortic valve regurgitation. During this surgery, the damaged valve is removed and replaced with an artificial valve. The valve replacement is typically an open-heart surgery.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.

Most of the time, you won't know the exact day you got pregnant. Your doctor will count the start of your pregnancy from the first day of your last menstrual period. That's about 2 weeks ahead of when conception happens.

The Ortolani method is an examination method that identifies a dislocated hip that can be reduced into the socket (acetabulum). Ortolani described the feeling of reduction as a “Hip Click” but the translation from Italian was interpreted a sound instead of a sensation of the hip moving over the edge of the socket when it re-located. After the age of six weeks, this sensation is rarely detectable and should not be confused with snapping that is common and can occur in stable hips when ligaments in and around the hip create clicking noises. When the Ortolani test is positive because the hip is dislocated, treatment is recommended to keep the hip in the socket until stability has been established

Hypothyroidism during pregnancy is treated with synthetic thyroid hormone, thyroxine (T4). Postpartum thyroiditis—inflammation of the thyroid gland—causes a brief period of hyperthyroidism, often followed by hypothyroidism that usually goes away within a year. Sometimes the hypothyroidism is permanent.

James Burke Fine DMD by James Burke Fine DMD Periodontal disease is a gum condition caused by the buildup of bacteria along and below the teeth's gumline. Acute forms are usually associated with pain from oral tissue gone bad – also known as necrotizing gingivitis or trench mouth – whereas chronic forms are painless but have a more long-term impact on your overall, systemic health. The most common chronic form is gingivitis, whose bleeding, puffiness and redness comes from an organized mass of bacteria called plaque. You may know it can advance into a form called periodontitis. If these conditions are left untreated, however, it can also lead to infections within other parts of the body, such as the lungs.

Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar)
