Babies' eyes form early in the fetal stage. They can be damaged in utero if the mother experiences German measles or abuses illegal or prescription drugs. In rare cases, otherwise healthy babies are born with blindness or other eye problems.The eyes continue to form after birth, so it is important to have frequent eye exams to look for infection and other disorders.
Positive reinforcement comes in many forms. Sometimes it is praise from another, and sometimes it is merely getting what is wanted. Scientists have used positive and negative reinforcement in experiments to see how it effects a person's performance on puzzle solving and other tasks. Not surprisingly, people and animals both perform better when they get something good out of it. Exactly like our dog that sits for a treat, or our kids who behave at the grocery store so they can have some candy, test subjects are willing to work to get what they want.
Several ongoing studies seek to improve techniques for detecting, treating and preventing cancer in BRCA1 and BRCA2 mutation carriers. As knowledge in these areas continues to expand, genetic counseling methods and outcomes have improved.
Intravenous bags, whether the tiny 50 mL size or the standard 1000 mL one, all have the same general layout. This allows health care workers to concentrate on the task at hand and not to have to evaluate a new infusion method each time an IV bag is hung. Some suppliers have changed the material used to manufacture IV bags, but the bag layout remains the same.
Doctors normally perform eye tests in an office, but it is possible to administer a test in the privacy of your home. Eye tests involve reading letters of different size off a chart called the Snellen chart. You stand 20 feet away from the chart and read as many letters as possible. Where you stop reading determines your vision acuity, which helps optometrists know whether you have a vision disorder. While performing the test at home is possible, you also need a prescription from an eye doctor, and you receive a comprehensive consultation that goes over symptoms of eye diseases.
An eye test given by a qualified eye doctor is very important for maintaining good eye health. During the eye exam, the doctor (also known as an optician) will test for various types of vision problems, including glaucoma, cataracts and general deterioration of your vision. If you have not had an eye test done in several years or if you feel like your vision may have changed, you need to get an eye test in the near future.
Visual field tests measure an individual's central and side vision. The tests are helpful in detecting signs of glaucoma, optic nerve disease, and eyelid problems such as drooping. Testing the visual pathways to the brain allows medical professionals to find tumors and macular diseases. All eye tests are done one eye at a time. There are several types of testing methods and they are divided into several different categories.
Occult gastrointestinal bleeding can be caused by a variety of conditions, some of which as very serious. Because of this, having an evaluation by a doctor is vital in determining the cause of bleeding.
An ocular burr is used by a doctor to help remove a rust ring from the eye's cornea. A rust ring often forms when a foreign body made of steel or iron has remained on the cornea for more than a few hours, says merck.com. Occasionally, when a foreign body hasn't implanted itself in the cornea, your ophthalmologist can use a burr to remove the object before she removes the ring. Diamond-tipped burrs are often used to treat recurrent corneal erosion, according to the British Journal of Ophthalmology.
When you undergo an eye exam your ophthalmologist or optometrist will perform an eye exam to test your vision and look for any sign of eye disease. Your doctor will use a variety of instruments, aim bright lights in your eyes, and test your vision as you look through a series of lenses. The goal of the eye exam is to evaluate different aspects of your vision. Once completed, your doctor will give you an assessment of your visual acuity and, if necessary, a prescription for eye glasses or contact lenses. He or she may also talk to you about…
When you undergo different types of eye exams, your eye doctor is doing more than making sure you don't need to buy glasses or contact lens. In fact, your doctor is evaluating your vision to detect any problems with your eyes. Typically before any type of eye exam, your doctor or technician asks you about your medical history and whether you suffer from any diseases such as diabetes, and whether you have noticed any vision changes.
Gallstones, made of cholesterol and other components in the bile stored in your gallbladder to help you digest fat, form when your gallbladder does not empty properly or if your bile contains too much cholesterol. Gallstones can cause pain in your stomach, upper right abdomen or back or between the shoulder blades and can potentially lead to life-threatening complications, such as gallbladder infection or inflammation of the pancreas (See References 1 and 2). Prevent gallstones and their painful symptoms and complications simply by following a healthy diet and leading an active lifestyle.
Whenever applying for a new job, it is important to know what the job requirements are, including any special vision equipment that might be necessary for the job. If a prospective employer requires that you use a visual display unit or computer as part of the job requirement, it is within your rights to request a vision exam, at no charge, to make sure that your vision will be protected. As with any transaction, it is important to know what your rights are.
During an eye exam, an ophthalmologist, or eye doctor, checks for eye diseases that could lead to vision loss if untreated. There are several types of eye tests that can be performed to detect the presence of eye problems. These include nearsightedness, glaucoma and color blindness. When not diagnosed or properly treated, these conditions can result in eyestrain, headaches and blurred vision or vision loss.
Many websites and books offer brain teasers and IQ-enhancing puzzles and games. Each puzzle or brain teaser has a specific solution or trick that can be used to make the puzzle simpler. One common puzzle that users have trouble with is an eye puzzle, which requires you to unfocus your vision or look at a picture from a certain angle to see the optical illusion.
According to the National Cancer Institute, esophageal cancer strikes over 16,000 new patients every year, with approximately 14,500 patients dying from the disease annually. Many alternative therapies have developed, including silver, usually diluted in water and sold as "colloidal" silver.
The gallbladder is a small pear-shaped organ that stores bile for the liver. According to the Mayo Clinic, a high-fat diet puts a person at risk for developing gallstones. Gallstones are deposits of hardened cholesterol in the gallbladder. Gallbladder attacks occur when these gallstones cause blockages. Fatty or spicy foods often trigger gallbladder attacks and should be avoided.
Eye color is determined by the pigment in the iris, the colored section of the eye. The most common colors--blue, green and brown--are primarily determined by the OCA2 gene, which controls the amount of pigment in a person's eyes. Eye color ranges from brown, the most common eye color, to green, the least common. Colors such as amber, blue, hazel and gray fall in between these two colors.
Ocular melanoma, a rare eye cancer, affects the part of the eye called the uvea. The uvea contains pigment-producing cells called melanocytes, and consists of the iris, ciliary body and choroid. The iris is the colored part of the eye. Iris melanoma develops when iris melanocytes become cancerous. The cancer usually remains localized.
The iris is the colored part of the eye, which controls the quantity of light entering the ocular globe through the black-centered pupil. According to the optometrist Dr.Ted Montgomery, the color of the iris is a genetic characteristic "determined by the amount of pigment present in the iris structure." The color of iris is controlled by a gene on chromosome 15 and another gene on chromosome 19, but some researchers believe there are more genes involved, reports PubMed. Although patterns and color shades are unique to each person, there are three basic types of iris.
Yearly visits to an eye care professional are a painless and essential part of taking care of your health. This visit may include a visual acuity test using the familiar Snellen chart. The Snellen chart begins at the top with a single large letter (often an E) with rows of increasingly smaller letters beneath. The smallest row of letters that the patient accurately reads is the estimate of visual acuity, with 20/20 considered normal vision. You can check your latest eye test or monitor retinal treatments by using a Snellen chart at home.
Malignant growth in the colon or rectum is referred to as colorectal cancer or colon cancer. Several factors such as age, diet, family history and chronic infections of the colon can cause colon cancer. Colon cancer is initially diagnosed by doctors during routine rectal examination and colonoscopy. To diagnose the cancer in detail, doctors will perform tumor histology (the microscopic study of a tissue section); this will categorize and describe the cancer in detail and determine its responsiveness to specific treatments.
If you're having vision problems you may want to visit your doctor for an eye exam. Some people choose to use glasses or contact lenses to correct their vision. If you don't want to deal with the hassle of glasses, however, you may choose to undergo corrective eye surgery. Corrective eye surgery has extremely high success rates and is usually relatively painless, according to the University of Iowa.
The gallbladder is a small organ in your digestive system that holds bile. When you eat, this bile is secreted, helping to digest your food. If your gallbladder is not functioning properly due to gallstones or gallbladder disease, eating certain foods that require more bile to be digested can result in pain and negative health effects.
Colons vary in shape and size. While all colons have loops, a redundant colon consists of extra loops which cause it to be longer than normal. The extra loops in the colon may have developed naturally or as the result of factors such as stress, toxins or dietary issues.
Safety is of primary concern when working with materials that create dust, fumes or toxins. All eye and face protectors are not created equal. There are different types of equipment to meet various needs and levels of exposure. Make sure you're covered--literally--by choosing the proper equipment for the job.
An ileostomy is a surgical procedure that is necessary when disease or injury has damaged the intestinal tract to the point that the body can no longer excrete waste. Many digestive health conditions lead to the need for an ileostomy. Some of these are, Irritable bowel disease, colon or rectal cancer, injury to the area by an accident, or familial polyposis. According to the textbook "Colon and Rectum," the need for surgery evolves over a period of time, usually after acute flare-ups
Melamine in an industrial chemical used in the production of thousands of products from plastic and fertilizers to concrete and tiles or bricks. However, melamine has a protein-like chemical structure that can be mistaken for milk with less sophisticated testing methods, and in 2008 it was discovered to be widely used as an adulterant in infant formulas produced in China. (Melamine was also found in pet food from China in 2007.)
When caught early, a patient suffering from colon cancer could have a life expectancy of up to five years. It is important that everyone get a regular colon exam after the age of 50 so that this disease may be caught in the early stages if it is present in the body. As each stage of colon cancer develops, the life expectancy rate decreases. If you are exhibiting any of the symptoms of colon cancer, you should be examined as soon as possible.
Hodgkin's disease (also known as Hodgkin's lymphoma) is a cancer of white blood cells called lymphocytes. Thanks to recent advances in treatment, the disease can be managed much more successfully now than in the past; according to the "Professional Guide to Diseases," the five-year survival rate for Hodgkin's as of 2005 was roughly 80 percent. Coping with Hodgkin's, however, is still a difficult experience. There are a variety of support groups and organizations where you can talk to people who know what you're going through and can offer you advice or help.
Esophageal burning is often caused by gastroesophageal reflux disease (GERD). And roughly 30 percent of adults experience symptoms about once a month, says Chemocare.com. In GERD, stomach acid can back up into the esophagus from high acid diets, in which citrus, fat and caffeine, among other problem foods, are consumed. Reflux can also occur when the esophageal valve that prevents acid from traveling up the esophagus becomes weak. What's more, GERD can result from the administration of chemotherapy drugs, reports BreastCancer.org. But relief is relatively easy to achieve.
If you suffer from irritable bowel syndrome (IBS), including ulcerative dolitis, Crohn's disease or any illness that causes severe gastrointestinal disturbances, you may, over time, develop colon scarring that can obstruct your bowels. If the scarring is severe enough to cause a blockage, your doctor may suggest one of several available treatments to ease inflammation and reduce scar tissue.
Bert Vogelstein, M.D., is a world-renowned cancer biologist and researcher with the Johns Hopkins University School of Medicine. After practicing as an oncologist for years, Dr. Vogelstein decided to pursue cancer research. His specialty is the study of colon cancer and colorectal tumors. In particular, his research has focused on the role of genetics and tumor suppressors in colon cancer.
The history of surgery to treat esophageal cancer goes back to the sixth century A.D. Treatment for esophageal cancer improved significantly during the 20th century. Unfortunately, despite past and recent progress, the prognosis for this disease is often poor; the five-year mortality rate is over 85 percent. Further research is necessary to find a truly effective treatment for esophageal cancer.
Generally considered safe, alcohol-based hand sanitizers like Purell are most often used when soap and water are unavailable. Detailed data provided by the manufacturer indicates no serious side effects from using Purell, which is largely alcohol-based. However, its high alcohol content has raised some concerns about the potential for substance abuse.
Colon cancer is the third most commonly diagnosed cancer in the United States. Family history is a key risk factor; as many as 1 in 5 of those diagnosed have family members who are similarly afflicted, and in 5 to 10 percent of cases, patients have inherited specific genes that predispose them to the disease. If you know you've inherited one of these genes, however, you may be able to take preventive measures.
Colon cancer that spread to the liver is considered to be stage IV. The liver is a common site for metastasis because part of the blood supply leaving the intestine actually connects directly into the liver instead of first being directed to the lungs. Nearly 50 percent of patients with colorectal cancer have cancer cells that have spread to the liver from the colon.
About 10 to 15 percent of breast cancer is believed to be caused by alterations in genes, according to a 1999 article published in "American Family Physician." Inherited breast cancer affects certain ethnic populations known for having blue eyes, such as Norwegians, Dutch and Icelanders, but there appears to be no direct link between blue eyes and breast cancer. Australian researchers found that the same gene that results in blue eyes affects breast cancer survival.
Kidneys are two bean-shaped organs, each about the size of a fist, located on both sides of the back in the midsection. Kidneys are the filtering unit for the bloodstream, working to remove all of the waste and toxins in the body through urination. There are several signs and symptoms that may indicate renal cancer in kidney transplant patients. However, most symptoms are not present until the latter stages of renal cancer.
Colonic therapy, also known as colon hydrotherapy or colonic irrigation, is an alternative medical procedure that uses low-pressure water to cleanse out the colon. Practitioners tout such benefits as restoring and maintaining colon health and the prevention of colon cancer and other colon problems. Trained professionals administer the therapy, and several U.S. schools offer the necessary training.
Nutritional supplement manufacturers use the term phytonutrient complexes to describe combinations of plant extracts featured in their "green" food products. While these nutrients, also known as phytochemicals, aren't essential to human survival, they promote good health.
Motilium is the brand name for the medicine with the active ingredient domperidone, a product that increases muscle contractions in the stomach and intestines, increasing the speed with which food moves from the stomach into the intestines and along the length of the intestines. You should consult your doctor or pharmacist for more information about domperidone.
Colon cancer is cancer of the colon or rectum. It is one of the most common forms of cancer, with more than 146,000 new cases diagnosed in 2009, according to the American Cancer Society. It is the third-leading cause of cancer-related deaths in the United States. Gas is only one of many possible symptoms of colon cancer. In many cases, people with colon cancer experience no early signs of the disease, according to the Mayo Clinic.
Colon polyps are abnormal growths on the lining of a person's colon or large intestine. Benign polyps can be precancerous or malignant and physicians usually need to test a tissue sample from a polyp to find cancer. Polyps can grow in the ascending colon or other parts of the large intestine. Doctors remove polyps that are discovered during an examination of the ascending colon to prevent future cancer development.
The colon is an important organ of the digestive system. The organ is divided into the cecum, ascending colon, transverse colon, descending colon, sigmoid and rectum. A pain in the colon could be due to several reasons; however, if the pain is specifically in the ascending region of the colon, the most likely cause of it is a disease known as colitis. Colitis is characterized by the inflammation of the ascending colon.
Colon cancer is typified by unrestrained proliferation of cells lining the colon (the longest portion of the large intestine). According to the National Cancer Institute (NCI), close to 106,000 new cases of colon cancers are detected annually in the United States. Similar to any other cancer form, colon cancer is also differentiated into different stages depending upon the growth and extent of multiplication of the cancer cells.
According to the National Kidney Foundation, about 51,000 adults in the United States are diagnosed with kidney cancer each year. There are several types of kidney cancer that affect people at all ages. Your risk of developing kidney cancer depends on a number of factors; one factor that can increase your risk for kidney cancer is exposure to asbestos.
Hodgkin's disease is a type of cancer in the lymphoma group of cancers. Lymphomas are cancers that occur in the lymphatic system. This body system is a component of the immune system. Hodgkin's disease is responsible for less than 1 percent of all cancers in America, making it a rare type of cancer, according to the Penn State Milton S. Hershey Medical Center. Knowing the signs and symptoms of Hodgkin's lymphoma is essential in knowing when consult a physician.
The most common form of pediatric eye cancer is retinoblastoma. A retinoblastoma is a tumor that forms in the retina, which is the nerve tissue in the back of the eyeball. The retina is where the rod and cone cells are found. This condition occurs in infants and young children all over the world. It can result in the loss of an eyeball, and it can even result in death if it is not found soon enough. Retinoblastoma is a major reason it is important to get children's eyes checked regularly by a pediatrician, an optometrist or an ophthalmologist. A…
