The eyes A close up of a young person's eyes. The eyes are responsible for four-fifths of all the information our brain receives. Here you can find out a bit more about how they work, common problems that affect vision and the work Sightsavers does to treat and prevent avoidable blindness. You can also find out more about the people whose lives have been changed thanks to donations from people like you. How do eyes work? (click image to see enlarged version or click here for text alternative) Graphic of an eye with information about its different parts The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea. Because this part of the eye is curved, it bends the light, creating an upside down image on the retina (this is eventually put the right way up by the brain). The retina is a complex part of the eye, but only the very back of it is light sensitive. This part of the retina has roughly the area of a 10p coin, and is packed with photosensitive cells called rods and cones. Cones are the cells responsible for daylight vision. There are three kinds – each responding to a different wavelength of light: red, green and blue. The cones allow us to see images in colour and detail. Rods are responsible for night vision. They are sensitive to light but not to colour. In darkness, the cones do not function at all. How do we see an image? The lens focuses the image. It can do this because it is adjustable – using muscles to change shape and help us focus on objects at different distances. The automatic focusing of the lens is a reflex response and is not controlled by the brain. Once the image is clearly focused on the sensitive part of the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medications, stents, and bypass surgery.

Many people have baggy and puffy lower eyelids. Lower Eyelid Surgery (Blepharoplasty) is the removal of excess fat and tightening of the skin, which can drastically minimize the appearance of baggy and puffy lower eyelids that makes everyone look tired and worn down. This procedure is just as popular with men as with women. A sense of well-being and alertness is the reason why most people elect to have this procedure. Lower lids surgery is a procedure that the best results are achieved when performed earlier than later. Dr. Lee has performed this surgery on patients who are 18 yrs old to 82 yrs old- all very happy with their results. The cause of baggy and puffy lower eyelid is due to a combination of herniating fat, excessive skin, and edema (water retention).

An intelligence quotient (IQ) is a total score derived from one of several standardized tests designed to assess human intelligence. IQ is a number meant to measure people cognitive abilities (intelligence) in relation to their age group. An I.Q between 90 and 110 is considered average; over 120, superior. Roughly 68% of the population has an IQ between 85 and 115. The average range between 70 and 130, and represents about 95% of the population.

Bioprosthetic valves used in heart valve replacement generally offer functional properties that are more similar to those of native valves.

Pediatric orthopedic surgeons at Columbia are using a new device with magnetic technology that avoids the need for multiple spine-lengthening surgeries to correct early-onset scoliosis, a severe curvature of the spine in young children. In April 2014, Michael Vitale, MD, the Ana Lucia Professor of Pediatric Orthopedic Surgery at CUMC and 1995 graduate of P&S, performed the first procedure in the New York area, using the device to treat a 5-year-old boy. When braces and casts cannot control scoliosis in young children, surgeons turn to growing rods, which help correct the curve while allowing the spine to grow. When spinal maturity is near, the rods are removed and a spinal fusion can be performed. But during years of treatment with growing rods, patients must undergo surgery every six months to lengthen the rods to keep up with the patients’ growth. A patient may undergo eight to 10 procedures, which are costly and result in lost time for parents at work and children at school. The new device—MAGEC (MAGnetic Expansion Control) rods—contains a mechanism inside the growing rods that allows surgeons to lengthen the rods with a handheld external magnet, without surgery.

Dr. Glenn Barnhart explains the symptoms of mitral valve regurgitation such as becoming short of breath. There are five structures of the mitral valve: annulus, leaflet tissue, chordae tendineae, papillary muscles, and left ventricle. All of these are taken into consideration when the mitral valve is leaking and not working right. There are four degrees of mitral valve regurgitation: mild, moderate, moderately severe,.

Every day, specialists deliver high-quality care in 68 disciplines in health centres across Canada. Yet many Canadians know very little about what many specialists actually do, and the important role these disciplines play in Canada’s health care system.

What Is Phonemic Awareness, Reading Program For Kids, Phonics For Children, Teach Your Baby To Read---- http://children-learning-reading.good-info.co----- What is Phonemic Awareness, Phonemic Awareness is defined as the ability to identify, hear, and work with the smallest units of sound known as phonemes. It is NOT the same as phonological awareness, instead, it is a sub-category of phonological awareness. For example, phonemic awareness is narrow, and deals only with phonemes and manipulating the individual sounds of words - such as /c/, /a/, and /t/ are the individual sounds that make up to form the word "cat". Phonological awareness on the other hand, includes the phonemic awareness ability, and it also includes the ability to hear, identify, and manipulate larger units of sound such as rimes and onsets. Phonemic awareness can be taught very early on, and will play a critical role in helping children learn to read and spell. While it's not set in stone on when a child can learn to read, however, I do believe that a child that can speak is a child that can learn to read. Children as young as two years old can learn to read by developing phonemic awareness, and they can learn to read fluently. Please see a video of a 2 year old (2yr11months) reading below. Below are several of the most common phonemic awareness skills that are often practiced with students and young children: Phonemic identity - being able to recognize common sounds in different words such as /p/ is the common sound for "pat", "pick", and "play". Phonemic isolation - being able to recognize the individual sounds of words such as /c/ is the beginning sound of "cat" and /t/ is the ending sound of "cat". Phoneme substitution - being able to change one word to another by substituting one phoneme. For example changing the /t/ in "cat" to /p/ now makes "cap". Word Segmenting - the parent says the word "lap", and the child says the individual sounds: /l/, /a/, and /p/. Oral blending - the parent says the individual sounds such as /r/, /e/, and /d/, and the child forms the word from the sounds to say "red". Studies have found that phonemic awareness is the best predictor of reading success in young children. Research has also found that children with a high level of phonemic awareness progress with high reading and spelling achievements; however, some children with low phonemic awareness experience difficulties in learning to read and spell. Therefore, it is important for parents to help their young children develop good phonemic awareness. Being able to oral blend and segment words helps children to read and spell. According to the National Reading Panel, oral blending helps children develop reading skills where printed letters are turned into sounds which combine to form words. Additionally, word segmenting helps children breakdown words into their individual sounds (phonemes), and helps children learn to spell unfamiliar words. As a young child begins to develop and master phonemic awareness skills, they will discover an entirely new world in print and reading. You will open up their world to a whole new dimension of fun and silliness. They will be able to read books that they enjoy, develop a better understanding of the world around them through printed materials, and have a whole lot of fun by making up new nonsense words through phonemic substitutions. For example, we taught our daughter to read at a young age - when she was a little over 2 and a half years old. Before she turned three, she would run around the house saying all types of silly words using phonemic substitution. One of her favorite was substituting the letter sound /d/ in "daddy" with the letter sound /n/. So, she would run around me in circles and repeatedly say "nanny, nanny, come do this" or "nanny, nanny, come play with me" etc... Of course, she only did this when she wanted to be silly and to make me laugh, at other times, she would of course properly refer to me as "daddy", and not "nanny". She is well aware of the differences between these words and is fully capable of using phonemic substitution to change any of the letters in the words to make other words. Give your child a head start, and.. pave the way for a bright, successful future..Click here to learn how to easily and quickly teach your child to read. http://children-learning-reading.good-info.co

Treatment of periodontal disease - Scaling and root planing

ARDS was recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patient’s arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. [3] ARDS is defined by timing (within 1 wk of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on 5 cm of continuous positive airway pressure (CPAP). The 3 categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 ≤100).

To diagnose COPD, your doctor will probably do the following tests: Medical history and physical exam. These will give your doctor important information about your health. Lung function testsLung function tests, including an FEV1 test. These tests measure the amount of air in your lungs and the speed at which air moves in and out. Spirometry is the most important of these tests. Chest X-rayChest X-ray. This helps rule out other conditions with similar symptoms, such as lung cancer.
