Red Eyes
Red Eyes samer kareem 11,154 Views • 3 years ago

Red eyes usually are caused by allergy, eye fatigue, over-wearing contact lenses or common eye infections such as pink eye (conjunctivitis). However, redness of the eye sometimes can signal a more serious eye condition or disease, such as uveitis or glaucoma.

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.

About 90% of these are minor and can be safely managed in primary care. Most of these will heal regardless of treatment, but the initial care can have a considerable influence on the cosmetic outcome. All burns should be assessed by taking an adequate history and examination.

Home Dialysis to Fit Your Life

#dialysis #uvahealth
If your kidney function is declining and medications and other treatments aren’t working, dialysis can offer life-saving care. UVA has one of the largest dialysis programs in the country. Nephrologist Daphne Knicely, MD, explains the types of home dialysis and how they can work to fit your life.

Transcript

Dialysis is just a way to replace the kidneys when they're not working anymore. So when the kidneys stop working, they stop getting rid of water, stop balancing the chemistry, stop getting rid of the toxins. Then dialysis does its job by balancing the chemistries, getting rid of the toxins, and help remove fluid. It doesn't fix the kidneys. It just replaces them.

I usually think of dialysis as two components. There's hemodialysis and peritoneal dialysis. So peritoneal dialysis can only be done at home. Hemodialysis can be done in a center, or it can be done at home.

Hemodialysis is where you have some sort of access to the blood. Either some sort of shunt in the arm that connects an artery and vein, or a catheter. And it allows for blood to leave you, go through a machine, get cleaned, chemistries balanced, and then comes back to you.

For home hemodialysis, the patient actually learns how to do that treatment. It's a very simple machine, very user-friendly. Training is usually about anywhere from four weeks up to eight weeks, and you work one-on-one with a nurse. You still see the physician. You come in about once a month, maybe twice a month, to get labs. You'll see a social worker, and a nutritionist at the same time.

Peritoneal dialysis takes place by putting a tube into your abdomen. And we take dialysis fluid that's chemically balanced. When we put it into the abdomen, it uses those little blood vessels to pull toxins out, to balance chemistries, kind of like little filters. Now, after it sits in there for several hours, we drain it out.

Anyone that needs dialysis is a candidate for home dialysis. There's not one type of dialysis that's going to make you live longer. They're all equal. The goal is to pick the type of dialysis that fits with your life.

Carotid Endarterectomy Approach
Carotid Endarterectomy Approach samer kareem 4,329 Views • 3 years ago

The objective of carotid endarterectomy (CEA) is to prevent strokes. In the United States, stroke is the third leading cause of death overall and the second leading cause of death for women.[1] Among patients suffering a stroke, 50-75% had carotid artery disease that would have been amenable to surgical treatment. Several prospective randomized trials have compared the safety and efficacy of CEA with those of medical therapy in symptomatic and asymptomatic patients. Data from these prospective trials have confirmed that CEA offers better protection from ipsilateral strokes than medical therapy alone in patients presenting with either symptomatic or asymptomatic carotid artery disease.

Organophosphate Toxicity
Organophosphate Toxicity samer kareem 4,856 Views • 3 years ago

Organophosphate poisoning results from exposure to organophosphates (OPs), which cause the inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine (ACh) in the body. Organophosphate poisoning most commonly results from exposure to insecticides or nerve agents.

Is Your Shoulder Pain an Impingement? 4 Quick Tests You Can Try. samer kareem 3,374 Views • 3 years ago

Rotator cuff pain commonly causes local swelling and tenderness in the front of the shoulder. You may have pain and stiffness when you lift your arm. There may also be pain when the arm is lowered from an elevated position. Beginning symptoms may be mild. Patients frequently do not seek treatment at an early stage. These symptoms may include: Minor pain that is present both with activity and at rest Pain radiating from the front of the shoulder to the side of the arm Sudden pain with lifting and reaching movements Athletes in overhead sports may have pain when throwing or serving a tennis ball As the problem progresses, the symptoms increase: Pain at night Loss of strength and motion Difficulty doing activities that place the arm behind the back, such as buttoning or zippering If the pain comes on suddenly, the shoulder may be severely tender. All movement may be limited and painful.

The Symptoms and Signs You May Have a Blood Clot
The Symptoms and Signs You May Have a Blood Clot samer kareem 1,477 Views • 3 years ago

They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg

How to use Ultrasound in Pregnancy
How to use Ultrasound in Pregnancy M_Nabil 21,759 Views • 3 years ago

A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.
