Jobs have a Risk of Lung Cancer

Most people know the cause of lung cancer due to smoking. But research in Italy showed a man who worked in certain jobs can increase the risk of lung cancer.

Consonni Dario researchers and colleagues from IRCCS Ospedale Maggiore Policlinico in Milan, find as much as 5 percent of men are affected by lung cancer associated with a particular job.

Yet according to the American Journal of Epidemiology, smoking remains a major cause for the disease of lung cancer. While chemicals and dangerous work that few can play a special role to the risk of lung cancer.

To see the relationship between lung cancer with the work, the researchers involved 2100 people diagnosed with lung cancer and 2120 healthy individuals with respect to age, gender and place of residence.

The result, obtained for 12 percent of men diagnosed with lung cancer worked in the mining, metal factory and some construction work.

Men with a risky job has probably 74 percent higher diagnosed with lung cancer.

The strongest association seen in the work related to ceramics, pottery, brick industry and non-metal industrial metal. In addition, in a small number of people also found a high risk of lung cancer in people who worked at a gas station, a glass worker and a welder.

This is probably caused by exposure to some chemicals continuously, do not use protective equipment like masks that special mamadai that can filter out small particles, or lack of medical examinations for the workers themselves.

As for women, the risk has not been established ditimbulkanya. This is because the number of women who are exposed to only a few that was not the right to take a conclusion. But the researchers speculate that this increase in risk of lung cancer in women who worked in the laundry and dry cleaners.

"The results of this discovery confirms the need for increased monitoring and continuous control of exposure to certain chemicals related to the job. It is good for prevention and as a compensation for the workers," said Dario Consonni, as quoted by Reuters on Tuesday (16 / 2 / 2010).

Avoiding Addiction Vibrator

Vibrator is a sex tool that is widely used women. This tool comes because many women who struggle to reach orgasm. With a vibrator nerves around the vagina is more active that makes women orgasm easier.

But there are fears began in western countries, the vibrator will make women become addicted and the risk of making it as a substitute for an intimate partner. Vibrator is used outside of the vagina to stimulate the clitoris.

Can a woman be so out of control in using a vibrator?

Sex expert and author Dr. Yvonne K. sex Fulbright says there is nothing wrong in using a vibrator in sexual intercourse.

"There's nothing dangerous, nothing is bad or unhealthy about using a vibrator," said Dr. Yvonne as quoted from FOXNews, Friday (12/2/2010).

He admitted there were some cases of women who use vibrators because it is difficult to reach a climax when done alone or with a partner without this tool.

He thinks there are two reasons why a vibrator many women liked:
1. The existence of clitoral stimulation.
Vibrator provides a direct and strong sensation of the 8000 nerve endings in the crown of women. This area is often not enough attention for sex.

2. The existence of the body's response.
The body will learn to respond in a way and a certain pattern when using a vibrator.

Women who use vibrators generally admitted his time more efficiently and could achieve orgasm and enjoyment as not break his spirit because it is difficult to reach orgasm during intercourse.

Women, especially in western countries also admitted more fun and safer to use sex toy than have sex with couples who may have contagious diseases.

To avoid a vibrator addiction, Dr Yvonne advised women not to make this as routine. Change the way of use such as by using it in the hands that can help rest the hand and avoid excessive fantasies.

Dr Yvonne says not to make sex aids women tend to choose masturbation than with spouse because it is not healthy for their relationship later. Married healthier than sex alone.

Detection of Sperm Quality In just 12 seconds

Ever felt curious about the quality of your sperm? How much, is it still good or not and so on? Now, researchers found a quick test to determine sperm quality in just 12 seconds. Remarkably again, this test can be done at home.

Loes Segerink and colleagues from the MESA + Institute for Nanotechnology at the University of Twente, Enschede, the Netherlands is the researcher who developed the test. They make a microfluidic chip size of 10 cm can detect male fertility through sperm.

Many men who want to test the quality of sperm but lazy or embarrassed to go to the doctor. Based on the researchers created the device. "With the successful systems we create, the problem can be overcome," he said as quoted Segerink from New Scientist, Wednesday (10/2/2010).

The chip works by counting sperm cells that were damaged through an electrode. From there is to know how many sperm are still functioning or not.

Generally, men who do the sperm test to the doctor took him about an hour to analyze. But the chip is made by Dutch researchers, you can save up to 48 seconds.

"This chip takes only 12 seconds with an error rate that is not much different from the calculation of sperm in general. This chip is manufactured to be applied at home than in hospitals," said Segerink.

But according to Michael Dunn, a researcher from the University of Oxford, the chip behind the advantage that there is potential for harm. "If the patient is not accompanied by experts as a test, there could be errors of interpretation and information about the fertility of their sperm," said Dunn.

"Even if a technology is ready for the market, the human ability in using technology that is worth considering," he added.

According to WHO, a normal sperm count is around 10-20 million per milliliter, or about 2-6 milliliters. The characteristics of healthy sperm, among others the amount above 10 million permililiter, fast and straight movements, the shape is relatively normal, good life skills, no bacteria and leukospermia a lot.

To test the quality of sperm, there are a variety of laboratory tests that can be done include:

   1. Test Semen (semen) complete, ie minimal steps to assess the categories of male fertility and scrotal function.
   2. Spermatozoa function tests, to determine the ability of sperm and live sperm membrane integrity.
   3. Test Post-coitus, which is related test Transportation sperm after intercourse.
   4. Test Microbiology and Virology, namely the analysis of semen by culture and test bacteria for antibiotic resistance.
   5. Immunological tests, yaiu rate of antibodies in the semen of their own sperm or the wife of blood serum antibodies.
