Swine Flu: The New Pandemic

Everyone’s all abuzz with panic nowadays it seems. That’s mostly because after SARS and bird flu, another new strain of virus has managed to rear its head. The H1N1 influenza virus, more popularly known as the swine flu, exploded on to the global scene last April via a large-scale infection in Mexico City.

I think everyone’s seen the images on CNN a thousand time. Surgical-masked Mexicans crowding the hospitals with worrisome shots of full hospital beds.The Center for Disease Control and the World Health Organization raised their alert levels in hopes of catching and cutting off the infection at the bud, but it seems that cases have been reported all over the world. It seems that the current fatalities from disease are from Mexico but everyone is just expecting for the other shoe to drop.

To understand all of this panic, ypou need to have a little background. Influenza, or more popularly known as the flu, is probably one of the most infectious diseases out there. Airborne and highly contagious, it could spread like wildfire all across the world. Now you’re asking what’s the matter with a few people getting a bit of sniffles? That’s because this isn’t your ordinary flu.

A lot of the flu viruses we are exposed to have been in the human system for hundreds of years. We’ve managed to build an immunity to these strains. The big problem that’s got everyone running scared is the idea that a flu strain has crossed species. This is what happened with the bird flu and now, with the swine flu. The pigs and birds have also built up resistances to these diseases, however, since humans are not used to them, these strains of flu have a very large potential of being fatal.

The last time a large-scale flu epidemic raged around the world, electricity was just coming into vogue and cars were all Model Ts. The Spanish Flu Epidemic of 1918 literally set the bar for every modern disease in terms of casualties. Fifty to a hundred million people worldwide died over a period of two years from 1918 to 1920 as the disease spread worldwide. Following on the heels of the Great War, it was a one-two punch that killed an entire generation of young men and women. What everyone’s afraid of is this: the 1918 epidemic was a subtype of the H1N1 flu virus, the same virus that seems to have crossed over and become a real threat to humans.

This is why the CDC is keeping a close watch on Mexico and hoping all of the subsidiary cases worldwide aren’t indications of the beginning of some worldwide epidemic. The good news about this is that the disease is treatable. Medicine and vaccine production alerts have been sent out by the CDC and most pharmaceutical companies have started churning out oseltamivir and zanamivir.

The problem with that is the demand may outstrip the supply depending on the swine flu’s virulence. More common antiviral drugs are also available but they’re not exactly definitive cures. They serve to weaken the symptoms and give you a fighting chance and prevent some of the worse flu symptoms like diarrhea and vomiting.

So as the world waits and watches the situation in Mexico, it would be a good idea to take a few precautions. Regular hand washes and vitamins can help make sure you avoid the initial infection of the swine flu. Avoiding pork’s not needed though. Swine flu can’t be transmitted through food. Remember to just a take a few preventive measures and you can come through clean and healthy.

Acupuncture and Electricity

Acupuncture has been shown to have great success in treating pain, stress, and a number of diseases. Acupuncture has a number of different techniques, and one of them is to apply a very low-level electric charge to the needle. This particular technique is creating interest in a field that was started in America in the 1930s and 1940s, but lost support soon afterward. This field is how to use low levels of electricity as a tool for medical therapy.

The initial discovery of acupuncture points on the body was by centuries of observation of the tender spots on the skin when a patient had certain symptoms. These acupuncture points can now be discovered and duplicated by scientists. They can find these same acupuncture points (given in any standard diagram) by using electrical apparatus. Scientists can also use infrared photography to find the temperature differences between these acupuncture points and the surrounding skin. So the acupuncture points have a different electrical behavior than the surrounding cells when the patient suffers from the associated symptom.

Several claims for acupuncture seem to get some support from other research using electricity. One scientist, Becker, has had tissue regrown by animals when he applied a low-level electric current to the site of the tissue. Even heart tissue has been restored without any scarring. Low level electric pulses have also been used to make bone fractures heal significantly faster than fractures left to heal on their own.

How do these two previous experience relate to the fundamentals of acupuncture? The basis of acupuncture is the correct distribution and flow of energy throughout the body. When energy is depleted, regrowth and stimulation and vitality do not occur. An acupuncture treatment restores the energy needed to a specific area. This research (especially the bone research) supports the claim that acupuncture sessions are of significant benefit for those with broken arms or other broken bones in the feet, ankles, and wrists, or other locations. Acupuncture has been known as an effective treatment for patients with heart palpitations, and the EKG results scientifically support that claim. Patients that are attached to an EKG machine and undergo an acupuncture treatment show a difference in the structure of the heartbeat, which is controlled by electric impulses from the nerves.

When an acupuncture needle is inserted into the skin, there is an electrical activity at that point, since the cells at that point are disturbed, and cells by their structure have various electrical charges within them. This is also shown by such techniques as Kirlian photography, where the photograph after a needle is inserted has a very different energy shape than before the needle insertion.

This exploration of the interaction between electricity and acupuncture has come back to expand the techniques used in acupuncture. The most basic technique for an acupuncture treatment is to use needles inserted into the skin of the patient. The location of the insertion, its depth and technique, bring about the results from the treatment. An additional technique is the application of heat, or moxa, which we will not go into. A third addition may be the use of herbs, either at the point of insertion, or given to the patient separately. A technique directly related to the above research, and also harkening back to the experiments of the 1930s and 1940s, is to affect the acupuncture points by a low voltage electric current. This is used in place of the needle. All these results and new ideas make research in acupuncture an exciting field to be working in and reading about.

Laser Hair Removal Devices

There are several different types of laser hair removal devices available today. These are alexandrite lasers, diode lasers, ruby lasers, and NeoDymium Yttrium Aluminum Garnets, which is commonly referred to as Nd:YAGs.

Alexandrite lasers became available for use in laser hair removal in 1997 when they were cleared by the FDA. Alexandrite lasers produce light beams in the red spectrum of visible light.
Their wavelength is 755 nanometers which is very effective but only safe on light skin. Generally, alexandrite lasers are considered long pulsed and because of this produce greater depth penetration. Five different types of the alexandrite laser are available. These include the Apogee, GentleLase, Epicare, Epitouch Alex, and Ultrawave II-III.

The FDA also cleared diode lasers for use in 1997 as an effective method of permanent hair reduction. Diode lasers produce a wavelength of 800 nanometers with pulse widths of 5-400 milliseconds. This type of laser has proved successful in the treatment of ingrown eyelashes and works very well on dark hair. The Light SheerXC is a diode laser that is extremely powerful. Other diode lasers include EpiStar, Apex-800, Iridex, and Mediostar.

Ruby lasers were also cleared by the FDA for laser hair removal in 1997, however, they did not prove as effective. Clinical research showed that the laser damage did not extend far enough down into the hair shafts to result in permanent laser hair removal. Originally there were five types of ruby lasers, of which only two are still available for commercial use. A Ruby lasers operate on a shorter wavelength system of only 694 nanometers.

NeoDymium Yttrium Aluminum Garnets have a longer wavelength which makes them more effective for longer term, and according to some people, even permanent laser hair removal. There are two types of Nd:YAGs lasers. These are the Q switched and the long pulse. All Nd:YAGs produce a wavelength of 1064 nanometers. The Q, switched NeoDymium Yttrium Aluminum Garnets has a very short pulse of about one nanosecond. Long pulse NeoDymium Yttrium Aluminum Garnets have a pulse of about a millisecond and can be used on all skin types.

The pulse duration, or pulse width, of lasers used for hair removal is the timing of the light energy. It is usually measured in milliseconds. Most lasers used for hair removal have a maximum pulse duration in the 20 to 40 millisecond range. Longer pulse widths are generally considered more effective and produce fewer side effects.

Each type of laser produces a specific spot size which is measured in millimeters. The spot size is the size, or width, of the beam of light at the laser sends out. A spot size of seven to 10 mm is considered acceptable for laser hair removal.

Most lasers have three main parts, an energy source, and active medium, and an optical cavity, also known as a resonator. The energy source is a device that supplies energy to the active medium. Laser hair removal devices use electricity as their energy source. The element of the active medium contains atoms that can both absorb and store the energy. The optical cavity is the part of the laser that contains the active medium. Lasers are defined by the elements they use.

Dangerous Bad Habits

Some bad habits are just annoying, but others are actually dangerous. It is these dangerous bad habits that can really get you in trouble. Some people like to take risks. Others do not think about how their bad habits could affect them.

Bad habits can be nothing more than not paying attention to your physical condition. If you are taking sedating drugs, it would be a bad habit if you continually worked in this condition. If you work two jobs, it can be a dangerous habit to work when you are sleepy. You would need to find a safe way to get enough sleep to work.

Many people have bad habits around electricity. They may use frayed extension cords without thinking. This is a bad habit that can lead to electrocution or fire. Using ladders, especially metal ladders, around power lines is another bad habit that is dangerous.

Some people have dangerous bad habits that are just unnecessary by any stretch of the imagination. People, often younger people, like to stand on moving cars and “surf.” This is reckless behavior at the least. At the most, it can be deadly.

Many bad habits have to do with driving a car. People often forget how potentially dangerous driving can be if it is not done with caution. They drive so often that they become accustomed to taking the wheel without thinking. This leads to a number of dangerous situations.

Some people have bad habits of grooming themselves when driving. Women might put on make-up while driving. They believe that they can apply mascara and watch the road at the same time. It may work out for a long time, and then eventually there comes that time when they are not concentrating on the road enough and an accident happens.

The same can happen when men shave while driving. Or, it can happen when men or women groom their hair. Other bad habits include the way people use their cell phones when they drive. Sometimes people are so keyed in on their cell phones that they do not see the car in front of them.

Driving through high flood waters can be a very bad habit. People think they can get through the water and make it to the other side. If it happens often enough, they may get braver and braver. However, if they go too far, their vehicle could be swept away. It could lead to a very dangerous situation.

Drinking and driving is the ultimate in bad habits. If you do this, you are not only putting yourself at risk. You do not even know who else you might be endangering. It could be an infant, an elderly person, or a single parent. It could be someone just like you. You could kill them or make their lives a lasting misery. This is not a bad habit that you can let stand.

If you engage in dangerous bad habits, you have to ask yourself why you do it. There must be something you can do to curb your desire to put yourself and others at risk. Find out what that is, and do it.
