It can treat spider veins and tiny varicose veins just under the skin's surface. ... (If you have poor blood circulation feeding these tiny veins, the larger "feeder" vein must first be treated with surgery, endovenous laser or radiofrequency treatment, or sclerotherapy.) Endovenous laser treatment.

These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. ... Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s.

Sclerotherapy is a medical procedure used to eliminate varicose veins and spider veins. Sclerotherapy involves an injection of a solution (generally a salt solution) directly into the vein. The solution irritates the lining of the blood vessel, causing it to collapse and stick together and the blood to clot.

In Reye's syndrome, a child's blood sugar level typically drops while the levels of ammonia and acidity in his or her blood rise. At the same time, the liver may swell and develop fatty deposits. Swelling may also occur in the brain, which can cause seizures, convulsions or loss of consciousness. The signs and symptoms of Reye's syndrome typically appear about three to five days after the onset of a viral infection, such as the flu (influenza) or chickenpox, or an upper respiratory infection, such as a cold

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.

Gastroesophageal reflux disease (GERD) is a chronic digestive disease. GERD occurs when stomach acid or, occasionally, stomach content, flows back into your food pipe (esophagus). The backwash (reflux) irritates the lining of your esophagus and causes GERD. Both acid reflux and heartburn are common digestive conditions that many people experience from time to time. When these signs and symptoms occur at least twice each week or interfere with your daily life, or when your doctor can see damage to your esophagus, you may be diagnosed with GERD. Most people can manage the discomfort of GERD with lifestyle changes and over-the-counter medications. But some people with GERD may need stronger medications, or even surgery, to reduce symptoms.

Choking occurs when a foreign object becomes lodged in the throat or windpipe, blocking the flow of air. In adults, a piece of food often is the culprit. Young children often swallow small objects. Because choking cuts off oxygen to the brain, administer first aid as quickly as possible. The universal sign for choking is hands clutched to the throat. If the person doesn't give the signal, look for these indications: Inability to talk Difficulty breathing or noisy breathing Inability to cough forcefully Skin, lips and nails turning blue or dusky Loss of consciousness

This video show the steps in a total parotidectomy with VII nerve preservation. The patient had a malignant parotid tumor without VII nerve compromise.

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

A nerve root block is an injection of local anesthetic (numbing medicine) and steroid injected under X-ray guidance into the area where the nerve exits the spinal column. A nerve root block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve. A nerve root block may be diagnostic (a test to determine the source of your pain) and/or therapeutic (to relieve your pain). If you get a period of sustained pain relief from the injection, the block may be repeated. Sometimes the block is done to help identify whether or not surgery might be helpful and at what level such surgery might be most helpful.

A tracheotomy or a tracheostomy is an opening surgically created through the neck into the trachea (windpipe) to allow direct access to the breathing tube and is commonly done in an operating room under general anesthesia. A tube is usually placed through this opening to provide an airway and to remove secretions from the lungs. Breathing is done through the tracheostomy tube rather than through the nose and mouth. The term “tracheotomy” refers to the incision into the trachea (windpipe) that forms a temporary or permanent opening, which is called a “tracheostomy,” however; the terms are sometimes used interchangeably.

Doctors at the Mayo Clinic used 3D-printed models to prepare for their first-ever face transplant.

Possible complications could include: Difficulty healing. Infection. Stump pain (severe pain in the remaining tissue) Phantom limb pain (a painful sensation that the foot or toe is still there) Continued spread of gangrene, requiring amputation of more areas of your foot, toes or leg. Bleeding. Nerve damage.

Doctors have many options to choose from, including interferon (Avonex, Betaseron, Extavia, and Rebif ), glatiramer acetate (Copaxone), mitoxantrone (Novantrone), teriflunomide (Aubagio), fingolimod (Gilenya), dimethyl fumarate (Tecfidera), and natalizumab (Tysabri).

Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer. Fibroids range in size from seedlings, undetectable by the human eye, to bulky masses that can distort and enlarge the uterus. You can have a single fibroid or multiple ones. In extreme cases, multiple fibroids can expand the uterus so much that it reaches the rib cage. Many women have uterine fibroids sometime during their lives. But most women don't know they have uterine fibroids because they often cause no symptoms. Your doctor may discover fibroids incidentally during a pelvic exam or prenatal ultrasound.

Catheters can be placed in veins in the neck (internal jugular vein), chest (subclavian vein or axillary vein), groin (femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters).
