What Are the risks Associated With Radon exposure?

A: Radon gas is an odorless, tasteless, invisible gas which is produced as a result of the decay of uranium present in soil and rock. The gas can diffuse from the ground into the air, and can also seep into groundwater. Radon exposure may lead to cancer if the gas exposure occurs consistently over a long period of time. Radon is present in very small amounts in almost all of the world’s air supply. At these very low concentrations, there is no risk of radon exposure causing toxic effects. In some locations, such as areas where ventilation is inadequate or where increased amounts of radon gas are present, however, radon concentration may approach toxic levels. Low-ventilation locations such as...

I have been sick for the past week due to second-hand exposure to crack being smoked. How do you remedy this sickness?

A: I take two inhalers for asthma to help my lungs recover from periods after I have had the flu or colds. The first type of inhaler is a ''rescue'' inhaler called albuterol. The second inhaler has a cortisteroid that helps heal the bronchial tissue and conditions the bronchia to become less sensitive to allergens. There are several factors that can trigger the congestion and difficulty of breathing, including smoke, cold drinks and sinus problems like those associated with the flu or colds. I think it is a good idea that you see a doctor that works with respiratory diseases to see if you have asthma. My asthma was an adult-onset situation, which I believe was related to my smoking (various substances) during my 20''s. It becomes a chronic condition that is improved by regular treatment, and...


How To Identify The Individuals Who Are At risk To exposure To Blood Borne Pathogens - 10 Ways

A: Blood borne pathogens like hepatitis B, Hepatitis C and Human Immunodeficiency Virus can be transmitted from an infected person to another via blood and other bodily fluids. Some jobs may have work-related exposure to blood and potentially contagious substances. Physicians, nurses, employees of laboratories, home health care workers, emergency medical technicians, dentists and dental laboratory technicians are some of the people who are at risk to exposure to blood borne pathogens. Some others may also have the risk of coming to contact with these harmful microorganisms. Answering the following questions can help you find out whether you are risk to


STD/HIV risk Assessment and Investigation Question

A: I"ll try to answer your questions as clearly as I can from your information. 1. You are right. No one can diagnose only from the information you have given. 2.Any blood tests within two or three week of exposure are worthless. 3.Probably not. Three weeks is a short time for a chancre to appear. Chancres may appear as long as three months after exposure. 4. It is difficult to assess risk from an unknown partner. I can only guess, but I"d say your risk would be about 50%. The risk of sexual intercourse with an unknown one time only may be zero or it may be 100%. It"s only a guess. 5. Kissing while having a chancre on the lips can be at a high


Hiv risk Through ( 2 to 3 day old cut on thumb) & Small holes on the side of condom)

A: Dear Doral: Peace.  Let me begin by saying that HIV isn"t easily transmitted; exposure to blood, semen, or vaginal secretions from an infected person is a risk, not a guarantee of infection.   The degree of risk varies - a lesion (sore), or open cut provides the virus in these fluids good access to the cells HIV needs to reproduce; it doesn"t matter if at the tip of the penis or the scrotum, though undiagnosed or untreated infections might cause lesions at the urethra (opening at the tip of the penis) that would be less noticeable.  Holes in a condom that are visible to the naked eye would be large enough for HIV-containing fluids to contact your skin, but the amount and area across which that...


How to Minimize Your Radiation exposure Today

A: The new airport X-Ray scanners may be exposing us to harmful radiation. Although the TSA claims they are safe, the problem with radiation-emitting technology is that damage from exposure is often discovered in studies years down the road. Dr. Oz recently featured a show on our increasing exposure to radiation, claiming that the fastest growing cancer in women is thyroid cancer, possibly due to the increased use of dental x-rays and mammograms in recent decades. He demonstrated that on the protective apron you wear during dental x-rays there is a flap that can be lifted up and wrapped around your neck to protect your thyroid but that many dentists don`t bother to use it. There is also a "thyroid guard" for use during mammograms. You should...


What are the risks of Handling Petroleum Products, Such As Auto Fuel?

A: exposure to petroleum products like gasoline can affect the skin, eyes and respiratory tract. Petroleum tends to be most dangerous when its fumes are inhaled, but long-term exposure to the skin also carries risks. If one regularly comes into skin contact with petroleum products, the best method for reducing exposure is to wear gloves. If one, for example, pumps gas for a living, wearing gloves can cut down on skin exposure. Over time, handling of petroleum products may result in tissue death of the skin. One may develop a dry rash, or have cracked skin. If one is pumping fuel, then the best method to cut down risk is to wash hands immediately...

HIV exposure

A: Dear Sam: Thanks for caring so much for my thoughts, but the physician providing your care is the right person to ask.   The research on PEP is a little hard to assess - mostly comes from a small group of health care workers with significant exposures, some become infected, some do not, but that would happen anyway.  There seems enough statistical evidence to suggest that PEP is better than non-PEP. In theory, weakening HIV by attacking it with antiretrovial agents should reduce the chances of an infection occurring.  A real problem has been that in early PEP studies, many of the workers stopped taking the meds because of side effects.  Thus, I said "may" because I cannot speak definitively on the matter.  Would "probably" have...


Blood exposure

A: Hi Shann: Peace and all good things, and congratulations on your upcoming wedding. I think the easiest way to answer your question is to tell you that there have been tens of thousands of exposures to HIV-infected blood  to intact skin in the healthcare setting and very, very few transmissions (www.cdc.gov) even in the presence of large volume exposures to people known to be HIV positive. The fluids that transmit HIV are primarily blood, semen, and vaginal secretions.  The risk of transmission increases with the frequency (how often exposed), amount of fluid (volume) to which a person is exposed, the duration of that exposure (receptive being higher


What Is the Post exposure Prophylaxis For HIV?

A: Post exposure prophylaxis (PEP) for human immunodeficiency virus (HIV), also called HIV-PEP, is a treatment provided to people who are exposed or possibly exposed to HIV with the goal of preventing infection. It involves prescription medications, usually taken on a four-week regimen, and the patient needs to be supervised during treatment and subjected to testing to check for signs of HIV antibodies both after the treatment and after a set interval. People who need post exposure prophylaxis for HIV include individuals exposed to infected blood through needle sticks, bite injuries, and certain kinds of sexual activity. A common situation where post exposure prophylaxis for HIV may be recommended is an incident in a...
