Have you ever wondered what happens to a painkiller, like ibuprofen, after you swallow it? Medicine that slides down your throat can help treat a headache, a sore back, or a throbbing sprained ankle. But how does it get where it needs to go in the first place? Céline Valéry explains how your body processes medicine.

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.

Unlike open surgery that requires a large incision to access the liver, the laparoscopic procedure is performed with surgical tools and a camera inserted through a few half-inch holes in the abdomen of the living donor. Once the piece of the liver is dissected, the surgeon retrieves the graft through a small incision below the navel.

Liver transplant surgeon C.H David Kwon, MD, discusses the laparoscopic liver donor procedure more.

Lung cancer starts when cells of the lung become abnormal and begin to grow out of control. As more cancer cells develop, they can form into a tumor and spread to other areas of the body. To learn more about how cancers start and spread

Bone tumors include abnormal healing of an injury, inherited conditions, radiation therapy. It can also be caused by bone cancer or another cancer that has spread to the bone from other parts of the body. A bone tumor may cause a painless mass. Some people have dull, aching pain. And in some cases, minor injury causes a fracture near the tumor. Treatments include surgery and radiation. Some noncancerous tumors go away without treatment

Sialendoscopy can be both diagnostic and therapeutic. It is complementary to diagnostic techniques such as plain radiography, ultrasonography, computed tomography (CT), magnetic resonance sialography, and conventional sialography, all of which are traditional, time-tested methods for evaluating the salivary ductal system

A subdural hematoma is a collection of blood outside the brain. Subdural hematomas are usually caused by severe head injuries. The bleeding and increased pressure on the brain from a subdural hematoma can be life-threatening.

Recently a group of affected females from Cameroon has started raising the voices against an old cultural "Female Abuse" tradition which is "Breast Ironing". The point of this tradition is to inhibit the growth of the female breast so that they will avoid getting raped.

While an anal abscess is an infection within one or more of the anal spaces, an anal fistula (Choice B) is a tunneling between the anus or rectum and another epithelial lined space (eg, the skin overlying the drainage site). Fifty percent of patients with anal abscesses will go on to develop a chronic fistula from the involved anal gland to the overlying skin. Patients with fistulas typically present with an anal abscess that persists after incision and drainage, or with a pustule-like lesion in the perianal or ischiorectal area that continually drains. Surgical repair is usually necessary to eliminate the fistula while preserving fecal continence.

Parkinson disease (PD) is a common neurodegenerative condition. Typically beginning in the sixth or seventh decade of life, it is characterized by the unilateral onset of resting tremor in combination with varying degrees of rigidity and bradykinesia. PD was originally described by James Parkinson (1755-1824), a man of many talents and interests. Parkinson published works on chemistry, paleontology, and other diverse topics. Early in his career he was a social activist championing the rights of the disenfranchised and poor. His efforts in this area were enough to result in his arrest and appearance before the Privy Council in London on at least one occasion. In collaboration with his son, who was a surgeon, he also offered the first description in the English language of a ruptured appendix. His small but famous publication, "Essay on the Shaking Palsy," was published in 1817, seven years before his death. The clinical descriptions of 6 cases was remarkable in part because he never actually examined the people he described. Instead, he had simply observed these people on the streets of London.
