Giant cell arteritis is an inflammation of the lining of arteries. Most often, it affects the arteries in your head, especially those in your temples. For this reason, giant cell arteritis is sometimes called temporal arteritis. Giant cell arteritis frequently causes headaches, scalp tenderness, jaw pain and vision problems. If left untreated, it can lead to stroke or blindness. Prompt treatment with corticosteroid medications usually relieves symptoms of giant cell arteritis and may prevent loss of vision. You'll likely begin to feel better within days of starting treatment. But even with treatment, relapses are common. You'll need to visit your doctor regularly for checkups and treatment of any side effects from taking corticosteroids.
The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.
With an Ophthalmoscope, light is shone into the eye and the retina and the optic nerve is examined. This is called as Examination of the Fundus. This is what the eye-doctor sees when he peeps into your eye! Through the transparent cornea, into the dark interior. The Fundus Exam When he looks into the eye with the Ophthalmoscope, he sees a orange glowing interior. That is the retina. The retina is actually transparent. It appears bright because of blood vessels in the choroid layer below. It is like looking at your ear against the bright sunlight. The yellow circle is the Optic Nerve, the cable of vision! A red, shiny dot attracts attention. That is the macula. If indicated, the exam of periphery of the retina is done with an Indirect ophthalmoscope. The ophthalmologist wears this instrument on the head and focuses the light into the eye with a lens held in his hand. This is usually done in a dark room.
Retinoblastoma is an eye cancer that begins in the retina — the sensitive lining on the inside of your eye. Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images. A rare form of eye cancer, retinoblastoma is the most common form of cancer affecting the eye in children. Retinoblastoma may occur in one or both eyes.
A parasitic twin (also known as an asymmetrical or unequal conjoined twin) is the result of the processes that produce vanishing twins and conjoined twins, and may represent a continuum between the two. Parasitic twins occur when a twin embryo begins developing in utero, but the pair does not fully separate, and one embryo maintains dominant development at the expense of the other. Unlike conjoined twins, one ceases development during gestation and is vestigial to a mostly fully-formed, otherwise healthy individual twin. The undeveloped twin is defined as parasitic, rather than conjoined, because it is incompletely formed or wholly dependent on the body functions of the complete fetus. The independent twin is called the autosite.
This is an educational video for the prostate cancer patients and their families. Depending on the individual patient, a radical prostatectomy, might be a procedure that your urologist could recommend as treatment. Here is a brief demonstration of this procedure.
If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth. It also creates holes in the tooth called cavities. Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture.
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.
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.
The menstrual cycle is the monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. Each month, one of the ovaries releases an egg — a process called ovulation. At the same time, hormonal changes prepare the uterus for pregnancy.
