Ovarian teratoma is a type of germ cell tumour. Germ cell tumours are cancers that begin in egg cells in women or sperm cells in men. There are 2 main types of ovarian teratoma. Mature teratoma, which is benign. Immature teratoma, which is cancerous.

This patient presented to the ER for umbilical pain and had a history of umbilical hernia. He was concerned about the possibility of incarceration of the hernia.

In this video we explain how the clinical exam helps to differentiate a simple painful hernia from an incarcerated one.

Biliary atresia is a rare disease of the liver and bile ducts that occurs in infants. Symptoms of the disease appear or develop about two to eight weeks after birth. Cells within the liver produce liquid called bile. Bile helps to digest fat.

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

Business Insider's Michelle Yan has been nearsighted since she was 9 years old. After laser eye surgery, she has 20/20. She walks us through the pre-surgery steps, the actual surgery which the doctor referred to as a spa for eyes, as well as the recovery process.

Don't miss the suggestions and recommendations she has for all those who are planning to undergo laser eye surgery for themselves, towards the end.

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism. The goal of the treatment is to reshape the cornea to correct the refractive error of the eye.
The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye's total optical power. Altering the curvature of the cornea changes the way light rays enter the eye. As a result, the light rays can be focused properly onto the retina for clearer vision.
For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape.
The outer layer of the cornea - the epithelium – is capable of replacing itself within a few days after being damaged or removed. The deeper layer of the cornea – the stroma, on the contrary, is a permanent corneal tissue with very limited regenerative capacity. The stroma, if reshaped by a laser, will remain that way permanently.
In this procedure, a thin, circular "FLAP" is created in the surface of the cornea to gain access to the permanent corneal tissue. This can be done with a mechanical cutting tool called a microkeratome, OR, for a blade-free experience, by a femtosecond laser. An excimer laser is then used to remove some corneal tissue to reshape the cornea. Excimer laser uses cool ultraviolet light beams to vaporize microscopic amounts of tissue in a precise manner to accurately reshape the cornea. The excimer laser is computer-controlled and is programmed based on the patient’s refractive error. The flap is then laid back in place and is allowed to heal.
LASIK eye surgery is mostly painless and can be completed within minutes. Improved vision can usually be seen overnight.

PRK, or photorefractive keratectomy, was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. In PRK, NO flap is created. Rather, the epithelial cells on the eye surface are simply removed. An excimer laser is then used to reshape the cornea just like it does in LASIK.
The vision correction outcomes of PRK surgery are comparable to those of LASIK, but the recovery period is longer. This is because the epithelium is completely removed in PRK and it takes a few days to regenerate. PRK patients also have more discomfort and haziness of vision in the first few days after the surgery. Improved vision also takes longer to achieve.
PRK does, however, offer certain advantages. Because PRK does not involve creation of a flap, which contains both epithelial and deeper stromal tissue, the entire thickness of the stroma is available for treatment. The treatment range is therefore higher. This is particularly useful for patients with high levels of myopia or for those whose cornea is too thin for LASIK. PRK is also free of flap-related complication risks.

One man is speaking out about the potential risks of laser eye surgery, after he says the procedure left his vision permanently impaired.

This video shows the technique of suprapatellar tibial nailing as used for a segmental tibia fracture. The broken leg was treated with the nail to allow immediate mobility and range of motion; no cast was needed for this injury.

Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing. Frostnip, the first stage of frostbite, doesn't cause permanent skin damage. You can treat very mild frostbite with first-aid measures, including rewarming your skin. All other frostbite requires medical attention because it can damage skin, tissues, muscle and bones. Possible complications of severe frostbite include infection and nerve damage.

Fillings are a way for dentists to restore a partially decayed tooth. While many people fear the dentist, this procedure is typically quick, effective, and inexpensive. Without fillings, cavities can rapidly worsen. Seeing a dentist regularly can help you to monitor the condition of your teeth and plan for corrective procedures. According to the National Institute of Dental and Craniofacial Research, nearly 93 percent of adults between the ages of 20 and 64 have cavities, and at least 29 percent have decay that is untreated. Dentists can quickly identify tooth decay and then come up with a plan of action that involves filling teeth and restoring adverse conditions. You can do your part by sticking to a solid at-home oral hygiene routine. By simply brushing twice a day with a fluoride-treated toothpaste and flossing regularly, you can prevent the build up of bacteria-rich plaque and eliminate cavity-causing conditions.

A fracture of the scaphoid, though a relatively frequent wrist injury, is often ignored, overlooked, or mistakenly attributed to a wrist sprain. This is due in large part to the subtlety of its symptoms. Unlike most other broken bones, the area around the scaphoid may not be noticeably swollen or intensely painful. According to HSS Hand Specialist Scott Wolfe, MD, “because of the scaphoid fracture’s relatively innocuous symptoms, it may be mistaken for a sprain and remain undiagnosed for months or years, leading to long-term consequences of painful arthritis.” A scaphoid fracture is usually caused by a fall on the outstretched hand, and it occurs most often in young, active patients. Frequently, the injury occurs in sporting events such as skiing or snowboarding, although it can also occur as a result of a motor vehicle accident or similar traumatic force on the hand and wrist. Dr. Wolfe notes that extra vigilance should be paid to every wrist injury, since the fleeting symptoms of a scaphoid fracture - in addition to its complicated shape and precarious blood supply - can lead to a failure of the two fractured bone ends to unite (also called a nonunion).
