Several difficult and complex steps have to be gone through so that you can have your baby: harvesting your eggs; fertilization of the eggs by healthy sperm; implantation of at least one embryo into your uterus; pregnancy to term, and delivery of a healthy baby.

Ensuring a Good Egg Supply

So that you have the best chance of a successful pregnancy through IVF treatment, more than one egg at a time is removed for fertilization. Normally a woman will only shed one egg during each ovarian cycle, but a few days after the end of your period your ovaries will be stimulated with drug treatment to make them produce more than one egg. You’ll be given drugs, such as clomiphene or hMG (human menopausal gonadotrophin), so that your ovaries produce a number of eggs simultaneously.

Over the next week or so you’ll need to go to the fertility clinic every day so that the development of your eggs can be carefully monitored with ultrasound scans. As the eggs mature, the follicles containing them swell and produce increasing amounts of estrogen. A series of blood tests will detect this increase in estrogen, and the growth of follicles can be precisely measured and tracked by a daily scan.

Collecting the Eggs

When ovulation is imminent, your mature eggs are collected at your clinic under ultrasonic or laparoscopic guidance. Then
they’re ready for fertilization by your partner’s sperm.

Ultrasonic guidance The use of ultrasound pictures to guide the egg retrieval probe is less invasive than using a laparoscope. It can be carried out under light or local anesthetic, instead of a general, and you’ll need to spend only a few hours at the fertility clinic.

Laparoscopy. This is an another method of viewing your abdominal cavity. The laparoscope, a small, very thin telescope, is passed into your pelvic cavity through a small incision made in your navel. It gives the surgeon direct vision while using a fine, hollow probe to collect ripened eggs from your ovaries. You’ll need a general anesthetic for a laparoscopy, and a small amount of carbon dioxide gas will be injected into your abdominal cavity to separate the organs so that the surgeons can see them more easily.

Confirming Conception

The harvested eggs are mixed with your partner’s semen, and 18 hours later they’re inspected under a microscope to find out if any have been fertilized. It’s uncommon for all the eggs to be fertilized. It’s uncommon for all the eggs to be fertilized and develope into embryos, but two or three usually do. Fertilized eggs are incubated for 48 hours or more, when they will have divided into two to four cells. Provided they show no signs of abnormality, a maximum of three embryos are transferred to your uterus.

Every 7 out of 10 persons in the world are prone to be suffering from diabetes. A simple thought of diabetes brings a stream of fear and tension into one’s mind. Only a few people in the world understand the real problem of diabetes and its cause. Basically diabetes is caused by excess of sugar content in the main bloodstream of a person. This is in fact caused due to less or no secretion of a hormone called insulin by the pancreas. This makes the body cells to use less of the sugar in the blood and most of the glucose remains in the bloodstream itself. This causes diabetes to a person. A person living with diabetes is more prone to heart and blood circulation diseases than other persons.

A person can be diabetic due to many reasons. Diabetes information provides some of those reasons. These are obesity, high fat content in blood, or ancestral. There are more chances of a person to get diabetic if his parents are also diabetic. A diabetic person feels continuous urination, feels hungry all the time and experiences blurred vision.

Vision is a complex and delicate process that can be affected by injuries, aging, and various diseases. Vision problems are due mainly to errors of refraction the way in which the lens of the eye focuses light on the retina at the rear of the eye. The most familiar are Astigmatism, in which the cornea, the transparent membrane at the front of the eye, is misshapen. Light rays fail to focus on a single point of the retina, resulting in distorted images. Farsightedness, or hyperopia, in which light rays focus at a point just beyond the retina, blurring near objects. Nearsightedness, or myopia, in which light rays focus just before the retina, making far objects difficult to see. Presbyopia, a condition that develops with age, in which the lens loses some elasticity, resulting in farsightedness. Color blindness, in which the cone cells of the retina are unable to distinguish the full spectrum of colors. Most color blindness is hereditary, affecting men 10 times more often than women. Other forms may develop with age or be secondary to diabetes, glaucoma, medications, or accidental poisoning.

Diagnostic Studies And Procedures

Most vision problems are readily diagnosed by an ophthalmologist or optometrist. These eye specialists test visual acuity with a Snellen test, a chart with rows of letters or numbers in different sizes. Typically, the patient reads the chart, first using the naked eye and then with special lenses or instruments. Peripheral vision may be tested by a device that blinks lights on and off while the person looks into it. If a color vision problem is suspected, the patient will be shown patterns of colored dots and asked to identify objects traced in different colors. Eye drops may be given to dilate the pupils, in order to inspect the inside of the eye.

Medical Treatments

Vision problems involving refraction errors are usually treated successfully with corrective glasses or contact lenses that refocus the light rays on the retina. Because vision changes over time, a prescription for corrective lenses must also be changed periodically. With advancing age, more than one lens strength may be needed, which can be combined into bifocal glasses. Color vision abnormalities are some times treated with colored contact lenses, but these reduce visual acuity, distort three dimensional perception, and offer little help with light shades, generally the major problem area. Nearsightedness can be corrected with radial keratotomy. This outpatient surgical technique, developed in Russia, involves making a series of tiny radial incisions in the cornea. Each eye is done separately, with several days between operations. An eye patch or dark glasses are worn for several days. The full effects may not be felt for several months. In one long term follow up study, more than half of the patients reported fully corrected vision, and another one fourth said their eyesight was improved. Anyone contemplating radial keratotomy should make sure that the surgeon has a high success rate.

Alternative Therapies

Exercises

In the Bates method, exercises are used to improve poor or weak eyesight. Ophthalmologists discount their value, but others contend that the exercises balance the optic muscles, nerve, and other eye structures.

Nutrition Therapy

High doses of vitamin A are reputed to improve faulty color vision, but this has not been proven. However, vitamin A is essential for night vision; good sources include yellow and dark green vegetables.

Self Treatment

To test yourself for a possible refractive error, make a pinhole in a piece of paper and look through the hole at a well lit object. If the object is clearer this way, you probably need corrective lenses. If not, your blurred vision may be due to another disorder. In either case, seek professional care.

Other Causes of Vision Disorders

Glaucoma, cataracts, and certain retinal disorders are some conditions that impair vision. Amblyopic, or lazy eye syndrome, is common in children and may occur with strabismus, or crossed eyes. Diabetes and untreated high blood pressure can also affect the eyes, as can many drugs.

If the person is hypersensitive to bee venom, a sting requires an immediate injection with adrenaline, or epinephrine, which can prevent anaphylactic shock. An antihistamine also may be given. If avoiding bees is difficult, desensitization may be recommended. This involves weekly injections of diluted bee venom for a year or more to permit the body to build up resistance. Treatment for poisonous spider or scorpion bites depends on the creature involved and the severity of symptoms. Sometimes local therapy to ease discomfort is all that is needed. In other cases, treatment may require antivenin injections, hospitalization, and even life support until the crisis is past. Steroid injections may be given if the wound from a brown recluse continues to expand after the first 12 to 24 hours. A sting from a marine animal may require a tetanus shot, antibiotic therapy, and, depending on the wound, removal of the stinger and surgical closure. Painkillers and topical lotions containing an antihistamine, anesthetic, and corticosteroids also may be prescribed. In more serious cases, especially if shock occurs, hospitalization for intravenous therapy and oxygen support may be necessary. Immediate treatment for a poisonous snake bite usually involves extracting the venom by suction . Some doctors also cut open the wound and excise a block of tissue around the bite. If symptoms are severe, antivenin may be given intravenously for several hours or, less commonly, by intramus cular injection. However, antivenin itself could cause an anaphylactic reaction, so sensitivity must be tested first by exposure to a diluted solution of it. Even so, careful monitoring is essential after giving snake antivenin. A tetanus shot, antibiotics, and a painkilling medication will also be administered when indicated.

First Aid For Snake Bites

Start first aid immediately if you will not be able to reach a hospital emergency room within 30 minutes. Even after applying first aid, obtain medical help as soon as possible.

  1. Keep the victim from walking or otherwise moving around, because motion speeds distribution of the snake venom throughout the body. Have the person recline, preferably with the bitten part at or below heart level.
  2. Use a tie, belt, or rope to apply a light constriction band to a bite on the arm or leg, about four to six inches above the wound . Make it snug but loose enough to slip a finger underneath. Move the band a few inches higher if the area around it begins to swell. If moving the person is necessary, immobilize the limb with a splint, made from a blanket, towel, or rolled newspaper.
  3. If a snake bite kit is available, use the extractor in it to remove as much venom as possible , following the kit’s directions carefully. Prompt action is a must up to 35 percent of the venom can be removed if an extractor is used within the first five minutes after the bite has occurred.
  4. If a snake bite kit is not available, try to squeeze out as much venom as possible. The venom also may be sucked from the wound with the mouth because the digestive system neutralizes venom as long as the person sucking does not have any open sores or cuts in or around the mouth. While sucking out venom, be sure to spit out the venom and rinse the mouth periodically. In the past, first aid manuals gave instructions to make shallow cuts over the fang marks. Experts now feel that this action increases the chance of infection, so they discourage it. In fact, these incisions actually decrease the amount of venom that can be removed with an extractor.
  5. After removing as much venom as possible, wash the wound area thoroughly if soap and warm water are available, Alternatively, cleanse it with an antiseptic pad or wipe.
