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.
Conversion disorder, also called functional neurological symptom disorder, is a condition in which you show psychological stress in physical ways. The condition was so named to describe a health problem that starts as a mental or emotional crisis — a scary or stressful incident of some kind — and converts to a physical problem.
Hirsutism is stiff and pigmented body hair, appearing on the body where women don't commonly have hair — primarily the face, chest and back. When excessively high androgen levels cause hirsutism, other signs may develop over time, a process called virilization. Signs of virilization may include: Deepening voice Balding Acne Decrease in breast size Enlargement of the clitoris
Use warm water and sea salt. Soak the wart for 10 to 15 minutes in warm salt water to moisten the skin. Scrape the dead skin layers off the wart using a nail file, pumice stone or mild sandpaper. You could also use your fingers, but wash them thoroughly before and after, as warts can easily spread.
Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jellylike fluid. Small ganglion cysts can be pea-sized, while larger ones can be around an inch (2.5 centimeters) in diameter. Ganglion cysts can be painful if they press on a nearby nerve. Their location can sometimes interfere with joint movement. If your ganglion cyst is causing you problems, your doctor may suggest trying to drain the cyst with a needle. Removing the cyst surgically also is an option. But if you have no symptoms, no treatment is necessary. In many cases, the cysts go away on their own.

Pulmonary edema is almost always treated in the emergency room or hospital. You may need to be in an intensive care unit (ICU). Oxygen is given through a face mask or tiny plastic tubes are placed in the nose. A breathing tube may be placed into the windpipe (trachea) so you can be connected to a breathing machine (ventilator) if you cannot breathe well on your own. The cause of edema should be identified and treated quickly. For example, if a heart attack has caused the condition, it must be treated right away. Medicines that may be used include: Diuretics that remove excess fluid from the body Medicines that strengthen the heart muscle, control the heartbeat, or relieve pressure on the heart
This video: Blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.

A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus. Each of your knees has two menisci — C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.
Like any syndrome, fetal alcohol syndrome (FAS) is a group of signs and symptoms that appear together and indicate a certain condition. In the case of FAS, the signs and symptoms are birth defects that result from a woman's use of alcohol during her pregnancy.
