Archive for May, 2011

Actually I was medical student and in order to complete my project I have to present a seminar on any general topic so that it is useful for everyone. As every know HIV/AIDS is the common problem that ruins the life of many people. I was planning to give seminar on this topic and started collecting information about this. Generally HIV is considered as sexually transmitted disease and the other diseases are gonoherra etc. so educate people on the occurrence of HIV. I have started gathering information about it. I have collected the origin of AIDS and the present stats related to aids like it affects on the number of people, and the symptoms related to it. I have started surfing net in order to collect the various HIV symptoms that can helpful in detecting HIV.
The general symptoms are fever, head ache, swelling of glands. These are the symptoms fro the primary level of HIV. And the symptoms of the AIDS are Kaposi sarcoma, fatigue etc. I have divided my seminar in to here parts and in the second part I thought of discussing about the test that help in detecting the HIV. The HIV test is generally of two types, a screening test followed by confirmatory test. In screening test the sample of blood, urine etc is collected and it cannot determine the level of HIV in body. So confirmation test is performed and then determine whether the patient is suffering with positive HIV or negative HIV. The final part of the seminar is to give the clinical details where the effective treatment is given to AIDS. I have gathered the information regarding various Gum clinic. I have received applauds for this seminar and I felt very happy in discussing about the hot topic in world.

When your vision falls below 20/20 level you need to begin wearing full time eye wear in order to compensate for the change and to ensure that you are still able to continue an active and full life, with perfect sight. The problem that crops up at this time is the question of what visual aid is right for you, with the two most common choices being eyeglasses and contact lenses, with a third being LASSIE eye surgery – a topic for another discussion

First, even as an avid contact lens wearer, you will never escape having to wear prescription eyeglasses. Contacts are great if you don’t suffer from dry eyes and when all is healthy with your eyes in general. However, the moment you have tired, dry or infected eyes, your contact lenses need to go into hibernation and allow your eyeglasses to do their part in helping you see while you rest your eyes and give them time to heal.

Let’s talk affordability because your pocket dictates many of the choices you make.

Eyeglasses are the more affordable option as one pair may last you two or more years, if your eyeglasses prescription doesn’t change. Plus, the upkeep of their care is cheap.

Contacts require far more care. Disposable contact lens wearers buy new ones regularly; while those who wear hard contact lenses still need to pay for lens solution and other such products.

Let’s discuss comfort and convenience.

Eyeglasses are also far more comfortable and convenient because they’re easy and quick to slip on.

Contact lenses often dry up or dehydrate, causing discomfort and red eyes due to the span of usage. The recommendation is only to wear you contact lenses for eight hours consecutively per day and to give your eyes a complete rest from them for at least one full day a week.

If there is one thing that should not be missing amongst nurses and other medical practitioners, it would be a thermometer or Nurses pen torch. If you are an observant person, you would notice that this nursing equipment is never absent in hospitals, clinics and infirmaries. A thermometer is a device used to measure body temperature of patients especially those who are running fever. It works with the mineral called mercury found inside a tube in it. When temperature rises above normal, the mineral also rises up giving nurses or doctors to record the temperature readings. For others, a medical thermometer is nothing but a piece of glass commonly put into your armpit or mouth during a check up but for nurses, it is definitely one of the most important things that they must have.

Buying medical thermometers and other medical equipment for nurses and medical practitioners like doctors such as Sphyg and nurses stethoscope is not as easy as it seems. You need to make sure that you buy these things from a source that you can trust, from a source that can provide you with high quality products. If you are a nurse or a doctor, remember that you are dealing with the lives of others and you must see to it that you go to the best place to buy your medical paraphernalia such as those mentioned a while back. Do not settle for products that are cheap but their quality is compromised. It is your duty to save lives, not just money so when it comes to your equipment, be sure to get them from the best place you can.
