The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.

The eyelid is injected with a local anesthetic, a clamp is put on the eyelid, then the eyelid is turned over, an incision is made on the inside of the eyelid, and the chalazion is drained and scraped out with a curette. A scar on the upper lid can cause discomfort as some patients feel the scar as they blink.

Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy, the cause of most scoliosis is unknown. Most cases of scoliosis are mild, but some children develop spine deformities that continue to get more severe as they grow. Severe scoliosis can be disabling. An especially severe spinal curve can reduce the amount of space within the chest, making it difficult for the lungs to function properly. Children who have mild scoliosis are monitored closely, usually with X-rays, to see if the curve is getting worse. In many cases, no treatment is necessary. Some children will need to wear a brace to stop the curve from worsening. Others may need surgery to keep the scoliosis from worsening and to straighten severe cases of scoliosis.

Pain in the upper thigh can be difficult to diagnose because this area of the body contains many muscles, tendons, and ligaments. This kind of pain may often be due to minor muscle injuries that are treatable at home. When the pain is intense or does not go away, however, it may signal a more serious problem. In this video, we examine some common causes of pain in the upper thigh, along with any symptoms that may occur alongside. We also take a look at the treatment options and how to prevent this type of pain.

Sepsis occurs when chemicals released in the bloodstream to fight an infection trigger inflammation throughout the body. This can cause a cascade of changes that damage multiple organ systems, leading them to fail, sometimes even resulting in death. Symptoms include fever, difficulty breathing, low blood pressure, fast heart rate, and mental confusion. Treatment includes antibiotics and intravenous fluids.

Research from Mayo Clinic finds that half of elderly patients who start dialysis after age 75 will die within one year.

Lead study author and a health care delivery scholar with the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery, Dr. Bjorg Thorsteinsdottir says many elderly patients and their families feel that they have no choice but to start dialysis, with several expressing regret from having initiated therapy.

The findings were presented at the American Society of Nephrology's Kidney Week 2013 in Atlanta.

Hey everyone! When I started posting more squat and lower-body workouts last week, I got many requests for this video. I actually had already had a knee pain video, but I felt like I could make it a lot better, so I remade it.

For more information, check out my friend ‎@ChrisRaynorMD aka @stablekneez on Instagram. Dr. Chris is a great surgeon, creative content creator, and all around good guy. He knows a LOT more than I do about this stuff. If you're interested, check him out!

Knee pain can be caused by MANY things, and this video is not intended to diagnose or treat any medical conditions. Some issues cannot be solved with exercise or physical therapy alone.

However, I've found that building up do doing squats with a full range of motion can help with knee pain. It's interesting, because there are some fitness figures that are adamantly against deep squatting because they claim it is BAD for the knees. I like it, and I've found it to be a very natural position. However, I do think that many people may not be prepared for it. Like any exercise, it can potentially hurt you if you're not acclimated to it. You can use your arm to assist you through the motion until you're able to do it without your arms with no pain. I have a full YouTube video on this: www.hybridcalisthenics.com/deepsquat.

Beyond this, sometimes strengthening our calves and hamstrings can "mysteriously" fix our knee pain. Both of these muscle groups support the knees.

On the other hand, sometimes these muscles are simply too TIGHT. You muscle fibers may be getting too tight and constantly trying to hyperextend your knees. Savor some calf and hamstring stretches.

I should point out that my chosen hamstring stretch in this video, standing toe touches, are controversial to some. Again, I like them, so they're shown here. If you are against them or they hurt you, you're very welcome to choose a different hamstring stretch.

Finally, I talk about isometric exercises like the horse stance and wall sit that seem to help with knee pain.

I touch upon synovial fluid, which is largely responsible for healing and nourishing our joints. Synovial fluid mostly circulates with movement, so I've included some knee "circles."

Hope this helps!

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.
