Oral Sex Causes Transmission of Oral and Neck Cancer

January 27, 2011 By: medicmagic Category: Cancer, Sexual Health

Cancer on the head and neck are related to sexual activity. This is caused by human papillomavirus (HPV) which is the principal cause of this cancer. HPV can be transmitted through an oral sex type of sexual activity.

“This relationship is strong, especially oral sex associated with the increase in HPV infection,” said Dr. Greg Hartig, professor of Otolaryngology Head and neck surgery at the faculty of medicine and public health University of Wisconsin, according to healthday.

A study in 2007 in the New England Journal of Medicine found that young people with cancer on the head and neck were positive for HPV infection in the mouth are more likely to have a lot of vaginal and oral sex  with their partners in their lives.

In the study, having six or more oral sex partners during lifetime have a 3.4 times higher risk for oropharyngeal cancer – cancer of the tongue base, back of the throat or tonsils.

Researchers also reported that the tonsils and base of the tongue cancer has increased every year since 1973. The increase is also related to oral sex activity that is spreading among teenagers. In it, French kiss is also vulnerable to transmit HPV. Some types of HPV can cause cervical cancer.

According to Dr. A. Amesh Adalja, instructor in the Section of Infectious Diseases at the University of Pittsburgh Medical Center, HPV tend to have specific locations. HPV tend to survive in the first body area it meets. It can be the vagina (which in some cases can cause cervical cancer), or the mouth and throat.

In other words, the changing trend of sexual activity also cause changes HPV infection.

U.S. Centers for Disease Control and Prevention (CDC) reported that, in 2002, about 90 percent of men and 88 percent of women aged 25 to 44 years old were claimed to have had oral sex with opposite sex couples. Compared to 1992 which showed about 75 percent of men aged 20 to 39 years old and almost 70 percent of women aged 18-59 years old had oral sex.

HPV attacks will get more vicious if the person also smokes. Of the patients with HPV who smokes, only about 45-50 percent who survive. Meanwhile, from among non-smokers, 85 percent of people with HPV-positive tumors survived.

Traffic Noise Causes Stroke in Elderly People

Exposure to loud noise can cause a stroke in the elderly.

According to a research by the Institute of Epidemiology Cancer Society in Copenhagen, Denmark , exposure to noise traffic which is very loud is associated with stroke in people aged 65 years old or more.

The researchers found that for every 10 decibels or more from road noise, a person’s risk of stroke increased by 27 percent. Researchers also found evidence that noise limit for elderly people is about 60 decibels. For those aged less than 65, a significant risk is not founded.

The study involved more than 57,000 people between the age of 50 and 64 who lives near Copenhagen and Aarhus between 1993 and 1997.

According to the study authors, Mette Sorensen, a senior researcher at the Institute of Epidemiology Cancer Society in Copenhagen Denmark, researchers analyzed medical records and location of their home during the period.

Researchers then measured the exposure of traffic noise. When starting the study, 35 percent of participants have been exposed to noise levels greater than 60 decibels, and the majority (72 percent) lived in the same address during the study. The researchers estimated that the lowest level of exposure to noise is 40 decibels and the highest to 82 decibels. The result shows that 1,881 people had a stroke.

While this is the first study linking traffic noise and stroke, they were not surprised with the results. “Most previous studies have found the traffic noise are associated with other cardiovascular disease,” said Sorensen.

The study authors noted that their study occurred in urban areas and do not represent all of Denmark. He said that further research is needed to confirm these findings.

Sorensen estimates that 600 new cases of stroke each year in his country can be linked with road traffic noise. The 5.5 million population of Denmark had 12,400 new cases of stroke each year. Sorensen believes stress could be a factor why people are attacked by stroke.
“Exposure to traffic noise is believed to provoke the stress response and interfere with sleep, which may increase the risk of strokes, through mechanisms including increased levels of stress hormones, increased heart rate and blood pressure and impaired immune systems,” said Sorensen. Other risk factors for stroke may also influence such as air pollution, aircraft noise, smoking, diet, alcohol and caffeine consumption.

Common Causes Of Allergies

Are you often bothered by a runny nose, watery eyes, headaches, fatigue, itchy throat, and similar symptoms? Then you are probably suffering the effects of an allergy.  There are several causes of allergies, ranging from food to insect bites.  Oftentimes allergies can be misdiagnosed as the common cold.  However, when these symptoms persist, it is important to try to identify the allergen, or the cause of the allergic reaction.

No one knows for sure why one person has an allergic reaction to a particular substance, while another person does not.  However, it has been found that children, whose parents have allergic reactions, tend to be predisposed to allergies.  Of interest, is the fact that a child will not necessarily be affected by the same allergen that has an effect on their parent.       

Allergens can enter the body by various methods, they can be breathed in, touched, eaten, or injected.  However they enter, they are viewed by the body as being harmful, and as a result, the immune system produces histamines and other chemicals, to combat the invasion.  These are the early stages of an allergy.  The response will be the same, each time you are exposed to the allergen in the future.

Allergies can be triggered by breathing in certain irritants.  Some of the more common ones are pollen, animal dander, mold, and dust mites.  These airborne allergens are very difficult to battle because they are all around in the atmosphere.  In the case of pollen, these are constantly released into the air by trees, flowers, and grasses, and are especially prevalent during the summer, spring, and fall seasons. 

In terms of touch, substances like latex can cause allergic reactions.  Latex is made of rubber, which contains high levels of protein. Latex products include rubber bands, gloves, and balloons.  The allergic reaction is due to the response of the immune system, when an individual comes in contact with the natural rubber latex.  Symptoms of this type of allergy can include runny nose, sneezing, hives, and an itchy throat.  

Certain foods can trigger allergies.  Some of the more popular ones are: eggs and milk, peanuts, wheat, soy, shellfish, and tree nuts.  It is the proteins in food that is usually the cause of allergies. These are generally not broken down during cooking, or by digestive enzymes, and as a result, they precipitate allergic reactions in the body.  Common symptoms of food allergy include nausea, vomiting, abdominal pain, and diarrhea.

An allergic reaction to medication can also occur.  One of the drugs that persons tend to be especially allergic to is penicillin, or antibiotics which are penicillin based. Painkillers such as codeine and morphine are also known to cause allergic reactions.  Reactions can range from mild symptoms like rashes, to life threatening symptoms that can affect vital organ systems. 

Insect stings can also cause an allergic reaction when the body overreacts to the insect venom.  The insects that commonly cause this response are honeybees, ants, and wasps.  These all have a venom sac on their tail, which they use to inject the venom into a victim.

In rare cases, a serious allergic reaction known as Anaphylactic shock can occur, this can lead to dizziness, unconsciousness, difficulty breathing and sometimes death, and therefore requires immediate treatment. As we have noted, the causes of allergies are various.  However, once identified, every effort should be made to either avoid the allergen, or treat the symptoms of the condition.

Top 10 Causes Of Morbidity In The Philippines

If you have been living in the Philippines ever since you were born, you would be so used to having all these kinds of pollutions we have now. If you go to other countries, you would see a different sky. I never thought that the grass would be really greener and the sky would be actually be bluer in other countries.

A lot of people get sick here in the Philippines and they think that it is normal. They do not know that the causes of these sicknesses are because of these 10 reasons:

  1. Water pollution – Factories dumping toxic chemicals in the sea would have a domino effect. Fishes that we eat would be poisoned and when consumed by humans, it won’t be a good source of nutrition.
  1. Noise pollution – You think that noise pollution don’t cause sickness? Noise pollution can cause hypertension, high stress levels, annoyance and aggression
  1. Soil pollution – Plants and vegetables is a healthy food source. Of course, when polluted with chemicals, one would know the many effects in can cause.
  1. Population – The more the merrier? No. The more people there is in one country, the more sickness it can spread and at a faster rate.
  1. Lifestyle – Eating out? Fast food is very bad. Very unhealthy. It will make you sick!
  1. Limited resources – In the Philippines, where we were recently hit by the rice shortage crisis, people resort to eating alternatives or not eating at all. Also, resources of organic food is limited that only those people who are willing to pay a premium price can avail of the fresh organic food from selected places.
  1. Evolving sickness – Bird Flu transmitted to humans? Well, this is one effect of pollution but we can blame this on us, human beings, because we are the ones destroying the environment.
  1. Attitude – having a bad attitude would not only make seem your life longer but, it would actually make it shorter. Suicide rate in Japan and Hong Kong are among the highest when stock market crashes. In the Philippines, it’s not yet as high as those countries but, with this economic turmoil and instabilities, it would surely grow.
  1. Crime – sad but true. The crime rate here in the Philippines is high that I do not hear in the news a day passing without someone being killed.
  1. Global warming – and this, my dear friend is not a made up story. All the things we do contribute to this ticking time bomb. Smoke belching factories and cars, non-biodegradable materials, non-recyclable things and other things we do, unknowingly contribute to global warming which would soon be the number one source of disaster not only in the Philippines but to the world from sickness, to drought, earthquakes and high floods.
