Surgery

20.jpg

In medicine, surgery (from the Greek χειρουργική, or chirurgical, and latin chirurgiae meaning “hand work”) is a medical specialty that uses operative manual and instrumental techniques on a patient to investigate and/or treat a pathological condition such as disease or injury, to help improve bodily function or appearance, or sometimes for some other reason. An act of performing surgery may be called a surgical procedure, operation, or simply surgery. In this context, the verb operating means performing surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The patient or subject that the surgery is being performed on can be a person or an animal. A surgeon is a person who performs operations on patients. Persons described as surgeons are commonly medical practitioners, but the term is also applied to podiatrists, dentists and veterinarians. Surgery can last from minutes to hours, but is typically not an ongoing or periodic type of treatment. -Source

Modern Surgery Overview

21.jpg

Although it is sometimes difficult to determine when a medical procedure is considered surgery, a medical treatment that involves a cutting of a patient’s live tissue (e.g., hair and nails are dead tissue) is usually considered surgery of some sort. A medical procedure involving a drilling of live tissue in a body would often be considered surgery, but mere piercing of a body is not necessarily surgery since piercing is often done for taking samples or draining fluids from or injecting materials into the body, or setting up intravenous drip, and usually does not require suturing to close the pierced opening. Even if a medical procedure or treatment does not include cutting or drilling of live tissue in a body, it may be considered surgery, if it involves common surgical procedure or a setting, such as use of an operating room or table in a hospital, anesthesia, antiseptic conditions, typical surgical instruments, and suturing or stapling. Surgery is considered an invasive procedure. Examples of surgery without cutting the body may include debridement or closing (suturing or stapling) an open wound or applying skin grafts if done under typical surgical conditions. Many types of more complicated or involved surgery are obviously considered surgery, since they involve common surgical procedure or setting as mentioned above. A medical procedure may be surgery even if not all of the typical surgical conditions or procedures mentioned above are used. -Source

Highend Drugs Being Abused in the U.S.

Drug trade and abuse remain to be a major issue being faced by the U.S. government. This drug crisis that besets the country affects both adults and teens.

A new survey has found a rise in prescription drug abuse among teenagers. Data from the study showed that 24 percent of high school students or equivalent to more than five million have abused certain medications. This figure is up by 33 percent from 2008.

Among the teens who claimed having abused prescription drugs, 20 percent said their first experience was even before they reached the age of 14. In addition, 27 percent said they mistakenly believed that frequently using prescription drugs was safer than using cocaine or ecstasy or the so-called street drugs. [Read more...]

Cloned Heart

med2.jpgTechnology has revolved so much and because of this, everything seems to be  possible.  Researchers and scientist made up a revolution in revitalizing a deteriorating  heart though test has not been scheduled yet for humans. Organ decellurization is been tested to dead rat heart. They remove the cells from the heart, leaving behind only the nonliving fibers that give the heart its shape. Once the cells grew and functions like a new tissue, they inject cells from neonatal and newborn rats’ hearts into the left ventricle and propel oxygen and nutrients through the structure of blood vessels to support cell growth. After a couple of days, the heart is already pumping.

Vitamin D and cancer

Vitamin D is significant when it comes to the development of our organs. This vitamin is the regulator of calcium and phosphorous which is essential for the development of our bones. Vitamin D is also been said to be able to play a role in preventing diabetes and coronary diseases. The most recent findings on the benefits of vitamin D, though not yet extensively identified, is its ability to prevent the development of cancerous cells.

Calcitriol, a hormone of vitamin D is said to cause the death of cancerous cells. Several studies show that regular intake of vitamin D can deter the development of colon, breast, ovarian cancer and even prostate cancer. The link between vitamin D and colon cancer has produced the most interest among scientists and those in the medical field because it has shown a great potential.

Breakthrough Topical Cream to Make Life Easier for Epidermolysis Bullosa Sufferers

For most of us, lotions and topical creams are used for minor skin problems such as dryness and other cosmetic issues. For patients suffering from Epidermolysis Bullosa (EB), a breakthrough topical cream called SD-101 can actually help treat the wounds and lesions that result from their condition. While SD-101 is not a cure for the genetic condition itself, the cream will at least help ease the undesirable dermatological effects of Epidermolysis Bullosa.

According to Scioderm, makers of the SD-101, “Epidermolysis Bullosa is a rare genetic connective tissue condition that, in all of its forms, share the prominent manifestation of extremely fragile skin that blisters or tears with the slightest friction or trauma…Daily wound care, pain management and preventative bandaging are the only options available for caregivers, who are usually the parents or other family members.” Now, thanks to SD-101, faster healing of skin lesions and it its decreased spreading may be in sight for EB sufferers.

HIV Functionally Cured in 14 Adults and 1 Toddler

Recent news of an HIV cure has given hope to in the fight against AIDS. However, amidst much celebration, it should be noted that the cure does not really eradicate HIV. Instead, those cured are categorized as “functionally cured” with the effects of HIV under control, much like cancer in remission. Still, this is much cause to celebrate as it gives infected patients a chance to live a more abundant life free of endless medications and treatments. Obviously, it also frees up their finances with money that would have gone to medical bills free to be channeled to savings, mortgages, or even trivial things like phones, cosmetic procedures and beauty products.

As of this year, the total number of those functionally cured of HIV is 14 adults and 1 toddler. It may be a small percentage of the total number of HIV infected people, but this number expected to grow as more advances and breakthroughs come out of research and medical trials.

Research victories for a diabetes cure

A Harvard Medical School study indicate that it may be possible to stop type 1 diabetes and renew the insulin-producing beta cells that are destroyed by the disease. The scientists used a mix of three drugs designed to tame the out-of-control immune response attacking the pancreas, and an enzyme called alpha 1 anti-trypsin, which is normally produced by the body to ease inflammation.. This has only been tested on mice so far but trials with human patients will be run soon.

At the same time, progress is also being done towards a cure for type 1 diabetes in Sydney, Australia. Scientists from Westmead Hospital transplanted islet cells from a donor’s pancreas into patients’ livers, where the new cells began to produce insulin. This procedure was successfully done on eight patients and the results were very promising: the patients’ need for insulin shots dropped dramatically, to zero in some cases.

Antibiotics Management – Essential for Super-Bug Control

superbugsMany of today’s super-bugs have evolved resistance to some of our most potent and safest antibiotics mainly due to misuse of such medication that is worrying medical experts. Super-bugs are called such due to their ability to survive attack from previously effective treatment regimens like the new forms of tuberculosis that are resistant to most antibiotics. Penicillin is still one of our most potent forms of antibiotics but not for long, due to resistance and utter ineffectiveness of the drug against some of the newer strains of bacteria. Drug resistant strains of Staphylococcus, Clostridium and Enterococcus are now roaming our bodies, harder to tame than previous strains due to higher tolerance of present antibiotics. [Read more...]

People with poor vision now have an alternative to wearing corrective eyeglasses and contact lenses with a medical breakthrough in the field of ophthalmology. In the recent years, various research and trials have led to the development of LASIK (laser-assisted in situ keratomileusis).

LASIK is a type of refractive laser eye surgery used in correcting vision problems, like myopia, hyperopia, and astigmatism. The procedure is performed by well-trained opthalmologists.

Not everyone with a vision problem is a good candidate for undergoing LASIK eye surgery. There are many tests and exams required before a person is determined eligible. Generally, the patient who underwent LASIK only has a short recovery period and suffers minimal pain with the aid of medications.

There are some risks and complications that may occur with the LASIK eye surgery so it is best to talk to an ophthalmologist to discuss more about the procedure.
