Warts in Kids

Nearly fifty percent of children acquire warts at some time or the other. Warts, in the real sense are benign tumors which develop when keratinocytes, a kind of skin cell, is infected by the wart virus. There are many types of warts, the most common being rough bumps which appear on fingers and hands. Others are flat warts, genital warts, plantar warts, and molluscum contagiosum. The difference is based on the types, location, and painfulness of the wart. Common warts appear on fingers and hands and usually are painless. Plantar warts appear on the soles and are sometimes painful. Periungal warts show up around the finger and toe nail. Warts which appear on the face are flat warts.

The symptoms of the common warts are that the skin develops an irregular surface and becomes rough. A dome starts to appear after a day after infection. A popular myth is that warts have roots, but they dont. They grow on the epidermis, which is the top most layer of the skin. The black portion is because of broken veins and clotted blood.

Warts come and go at various stages of life like childhood and teenage years. They usually go away by themselves. But some can be very painful, can spread quickly and some of them wont go away for many years. Such kind of warts should definitely be treated. The most common treatment among the pediatricians is cryotherapy. They will freeze the warts using liquid nitrogen. Cantharidin can also be applied, which is a painless treatment but can result in painful blisters at the end of the day. The minus point is that these treatments sometimes cause blistering and some warts wont come off in one sitting. If the warts wont still budge they are further treated with strong salicylic acid, intralesional immune-therapy, bleomycin, or a pulsed dye laser. Aldara can also be used in worst cases. Because of some treatments the warts grow to the end of the blister, which results in a bigger wart and some might even result in a scar.

Besides other common wart treatments, the most well-known home remedy is duct tape. The affected area is covered with duct tape for about six days. If within that time period, the tape peels off, it should be reapplied. After the sixth day, the duct tape should be removed and the wart should be soaked in water and a pumice stone or emery board should be used to scrap the top skin of the wart. After this, the duct tape should be reapplied again within twenty four hours and the same procedure should be repeated until the whole wart disappears. This procedure takes at least two months to get rid of the wart completely. Some kids hesitate to put duct tape on parts which are visible, like fingers and legs. They can be encouraged by making them wear colored duct tape, other than grey. Many home wart freezing and removal kits are also available in the market whose help can be taken.

Warts spread by direct contact with the wart or any material which the infected person has used like a used towel which has been contaminated. It is contagious and hence it is recommended to stay away from it at the very sight of it. All the cuts, rashes and bites should be cleaned regularly and should be kept covered. Another measure for prevention is wearing closed shoes in public places.

Different Types of Acupuncture Treatment

When you normally think of acupuncture, you think of a person sitting with several needles inserted into their skin, into parts of the body like the ear, the arm, or the wrist. This is a good picture of a patient that is having an acupuncture treatment. These treatments last anywhere from a very short time up to thirty minutes or more, depending on the symptoms that are being treated. These needles are more frequently inserted just far enough into the skin to firmly keep them there, though an acupuncture practitioner may insert different needles somewhat further in depending on the treatment plan. Sometimes the needles are twirled in place, sometimes they are warmed before insertion, or have heat applied to them during insertion. Generally there is no discomfort when a needle is inserted, manipulated, or removed. Occasionally a slight twinge may be felt, but not more than that. Often during treatment a patient may feel more relaxed than when they came in, slightly warmer, or possibly feel a rush of energy during the treatment. Some patients feel no change during the acupuncture treatment, but their symptoms gradually change over a longer period of time, such as several weeks.

There are variations of acupuncture that do not rely on the use of needles. The ideas behind these are identical with standard acupuncture technique. The knowledge of acupuncture points, the organization of the body, and the importance of proper energy flow for a healthy body are all exactly identical to standard acupuncture therapy. The main difference is that the needle is replaced by a different technique to manipulate the acupuncture point.

In sonopuncture, a device that produces sound waves is applied to the point at which a needle would normally be inserted. In addition to the device that produces the sound waves, other devices that vibrate may also be used, such as tuning forks. There is a good deal of activity in this area, but results using these devices is not as well established as the results with traditional needle based acupuncture.

Another technique that has been in use since the middle of this century is to apply a low voltage electric current to the acupuncture point. Sometimes this is done together with insertion of a needle, sometimes it is done just by touching a small wire to the surface of the skin and connect a very low electric current. The feeling of the current is a very light tingling, and not any very noticeable or painful reaction. This technique using electricity was pursued independently in America and Europe in the 1930s and 1940s, but interest in the technique as a part of western medicine waned after that time.

Another variation of acupuncture that many more people have heard of is the use of acupressure. In this technique no instrument is used, just the technique of pressing a finger on the acupuncture point. This technique can be incorporated into such manipulations as shiatsu massage. This technique is also easy for a layman to do, and many have seen little cards with diagrams of pressure points on the hands and feet. Though these may be useful, the best use is made when the person understands more of the entire system of acupuncture rather than just where the acupuncture points are.

Acupuncture therapy has been extended beyond needles, and interest is continuing in using other instruments. Other techniques include the use of heat (a very traditional choice), friction, magnets, suction, and to the ultra-modern use of laser beams. Acupuncture is a very adaptable therapy, which yields very good results.

How is Wavefront Technology Used in Lasik Vision Correction?

The wonderful results of Lasik surgery have been improved by research adding new methods, such as Wavefront technology. This technology gives a Lasik physician the ability to see and accurately map even slight variations in the surface of the eye. This gives the physician the ability to more accurately tailor a Lasik operation to the individual, and result in even clearer vision.

The concept behind Wavefront technology was originally developed by astronomers, in order to indicate if a mirror or a lens had slight imperfections in it. It is very important in astronomy to get near perfect optics in order to clearly see the small light sources million of miles away in the universe. In the 1970s a sensor was created to electronically check these surfaces, and a type of this sensor is now used in the Wavefront guided Lasik procedures.

The idea to apply this technique, or to use this sensor, to the field of ophthalmology and later to the specific area of Lasik vision correction, was begun in Germany. The physician Josef Bille began using the sensor in his practice, and this started others to refine the sensor and how it is used and to apply it to Lasik technology. In 1997 the improved sensor, with greater accuracy and speed, was announced to the Lasik laser manufacturers. This allowed the companies that manufacture the Lasik equipment to develop tools using the Wavefront concept for each of their own laser systems.

The FDA approved the first Wavefront guided Lasik vision correction system for general use. Initially, the Wavefront sensor makes a map of the eye’s imperfections, and this map is sent to the laser that is used in the Lasik vision correction portion of the operation. This allows for precise eye alteration in order for Lasik to present the best vision correction possible.

The Wavefront technology used in Lasik can be described easily at an informal level. A small, flat sheet of light (called a wavefront) is passed through the eye, reflected off of the retina, and passed back through the eye and is captured by the Wavefront machine. If the eye were perfect, the light would return as a flat sheet and be captured that way by the Lasik machine. However, any imperfections changes the way that the light returns, and this is detected by the Wavefront part of the Lasik process.

A number of these small, flat sheets of light are sent into each eye from various directions and the results returned generated a three dimensional map of the eye to be used in the Lasik vision correction process. In addition to the commonly known problems of nearsightedness, farsightedness, and astigmatism, there are more than 60 other patterns that are known and can possibly be corrected for.

All of this information generated by the Lasik sensor is converted by software into a set of directions to be carried out by the Lasik excimer laser. Ask your doctor about this exciting advance in Lasik vision correction, and see if this procedure is right for you!

Even a Chicken Can Get Lasik Surgery

If you take the time to read any of the message boards or chat rooms on the Internet about Lasik surgery, you will wonder how anyone could get the courage to schedule a Lasik procedure, and why on earth they would want it. The various Lasik clinics sound anywhere from impersonal to something similar to Dr. Frankenstein’s lab, and the Lasik procedure itself sounds, well, surreal. It seems like the only people that would get Lasik are those with such bad vision that they cannot get out of bed without their glasses on.

Well, let me give you my story of how I chose Lasik. First of all, my vision is not good, but not terrible either. I can actually go to movies and see well enough to enjoy the film without glasses, but I need glasses to drive in order to read the street signs far enough away to act on the information. So for me, Lasik was not necessary, but I figured would simplify my life. I am outdoors very frequently, backpacking, climbing hills, and mountain biking. Glasses do not last long with me, and I am frequently grinding into the dirt which is not the best situation for contact lenses. For these reasons, Lasik looked very appealing.

The paragraph above might make you think I am a “manly guy” (hope so, think so!), so why on earth would I be afraid of a little Lasik scalpel? OK, technically Lasik does NOT use a scalpel but rather a “microkeratome blade”, but it is still a sharp object approaching my eye as part of the Lasik procedure. Nowadays Lasik physicians can get a laser to cut the flap in the eye, which is more than a little better than a sharp blade. But anyway, I had too many spills in my life to think any sharp object nearing my eye was a good idea, even under the skilled hands of a Lasik physician.

After talking with three (yes, three!) independent Lasik physicians, they each assured me that a 28 year old guy in nearly perfect health (OK, I exaggerate a bit) with moderate nearsightedness was one of the very best candidates for a successful Lasik procedure. I decided to schedule my Lasik procedure with the one that had the best track record, and coincidentally took the most time to explain everything about Lasik to me.

The Lasik surgery was not painful, though I accepted nearly everything they offered to give me comfort, including a sedative and a teddy bear. (I even went back to take a picture of me and the Lasik comforting teddy bear.) The only strange thing I remember about the Lasik procedure itself was a smell, something vaguely like hair burning. I suppose that was my eye. I am kind of glad they didn’t tell me to expect that before the Lasik procedure, I am not sure I would have gone in.

After a few years, I guess I was a nearly perfect Lasik client, as my eyes now have 20/20 vision and have remained stable long after the Lasik operation. I say that if you are a good candidate for a Lasik vision correction procedure, grab that teddy bear and go on in.
