Photodynamic therapy or PDT is a relatively new and non-invasive treatment for non melanomaskin cancer. It is mostly used in cases where the cancer is superficial and has not spread too deep. PDT is used mostly to treat Actinic Keratoses on the face and scalp, Basal cell carcinomas, Bowen s disease, as well as other conditions such as head and neck, mouth, lung and gullet cancer.

How does it work?
This treatment involves the use of a drug known as photosensitize or a photosensitizing agent with a specific type of light. When the photosensitizing agents get exposed to a light of a specific wavelength, a form of oxygen is produced, which eliminates nearby cancer cells. Every photosensitizer gets activated by the special light. The wavelength of the light determines how much it can penetrate into the body.

Process of Photodynamic therapy
Skin cancer is cured by PDT in several steps. The first step involves the injection of a photosensitizer into the patient s bloodstream. The blood cells absorb the agent all over the body, but in the cancer cells, it stays for a longer duration. Within 72 hours after the injection is given, the skin is exposed to light. The photosensitizer agent present in the cancer affected cells absorbs the light. An active oxygen form gets produced, which kills the cancer cells.

Other than killing the cancer cells directly, PDT uses two other ways to destroy cancerous tumors. The blood vessels in the tumor are affected, which leads to its death. The immune system also gets charged up and activated for fighting the cancer cells.

The light used for PDT is usually in the form of a laser. LEDs are also used to treat tumors present on the surface of the skin. The primary photosensitizing agent used in PDT is called porfimer sodium or Photofrin.

PDT can be undertaken in the outpatient department in a hospital. After taking the treatment, you have to keep the cancer affected area of the skin dry and covered for 36 hours. The area should be treated with care while showering. In case of thick skin lesions, repeat treatments are required within 4 weeks.

When is PDT used for skin cancer
PDT can be undertaken instead of surgery for treating basal cell cancer, Bowen s disease and actinic keratosis. PDT is used in cases where surgeries are required. It is used to treat large skin cancers, which are not very deep and in the case when several cancers develop in an area. For many skin conditions, PDT is a better remedy than undergoing a surgery.

Advantages of PDT

    There are no long term side effects.
    The process is less invasive compared to surgery.
    A very short time is taken for this therapy to be undertaken.
    The process can be repeated several times in the same area.
    Very less scarring takes place in the affected area.
    The cost of this procedure is lesser than surgery.

Should You Oil Hair If You Got Dandruff?

You're said to suffer from the problem of dandruff when the skin renewal cycle of your scalp accelerates all of a sudden. This brings about the development of patches of dead skin on your scalp surface and the resultant dry, skin flakes called dandruff.

The causes of this very common problem can be:

- Not shampooing your hair regularly can cause skin cells and oils to build up in the scalp leading to the outbreak of dandruff.

- Having dry skin can also cause dandruff to develop, which are less oily and smaller in nature.

- Even irritated oily skin, more commonly known as seborrheic dermatitis can cause you to suffer from these white skin flakes. The problem can be easily identified by its distinguishing yellow or white flakes over the red greasy skin surface.

- Sensitivity to certain hair care products and the presence of Malassezia (a type of fungus) are other causes that can lead to dandruff problems.

How to keep dandruff problems at bay?

Having poor scalp hygiene as well as the lack of proper scalp conditioning can cause dandruff to occur. Thus, proper conditioning of your scalp is vital for fighting the flakes that form on your head. Oiling your hair is the most effective measure that you can take against this scalp problem. While the ideal time to do this is at night so that you can wash it off the next morning, one should also remember that hair oil shouldn't be left on the hair for over 24 hours. 

Additionally, dry scalp makes it very easy for dandruff to develop as the oil-secreting glands found in the scalp's epidermal layers produce low or no natural oil. Application of oil helps in keeping the scalp nourished as well as enables glands to produce oil. But leaving it on for more than the recommended hours can intensify your dandruff problem and further accelerate the hair fall process.

While the link between the two may not be that obvious, gout happens to be a condition, which is sometimes related to arthritis. Therefore, it is sometimes known by the name 'gouty arthritis'.

While the issue may be severely painful, it does not mean that it cannot be reduced. And of course, when a person has the option and cutting the pain caused by gout drastically, his or her natural response is likely to be 'why not?'

Why Does It Happen?

The main reason for the occurrence of gout is too much uric acid being present in the body. The limbs of the body swell up, especially the extremities and this is known to be very painful. In many cases of gout, the swelling is especially evident in the big toe. Flare ups can last hours on end and may even get longer.

The people who wish to get the gout that is putting him or her through so much pain treated, there are quite a few options at their disposal. There are pain relievers that can be consumed under the advice of a medically qualified professional. While these pain relievers do not treat gout, but can reduces the intensity of the symptoms. Daily doses can be recommended as per the requirement and severity of the situation.

How to Get Rid of Gout?

While some anti-inflammatory drugs may have their effect, but no matter how bad the pain, aspirin is a drug that needs to be avoided. Intake of aspirin can make the problem even worse, which is the last thing a person would want!

The severe problems of gout can be dealt with the chemicals known as corticosteroids. Now, while these can provide some very effective pain relief, using them can be tricky due to certain side effects. One of these side effects is that since these chemicals are injected into the joints, they can significantly weaken them. The other side effect is that they slow the healing process of the wound. Both of these side effects are highly undesirable for any patients. These chemicals are usually prescribed by the doctors after a thorough analysis of patient's condition and history.

A person who drinks alcohol and suffers from severe condition of gout should look to scale back the amount which is consumed by him or her. This is because alcohol increases the amount of uric acid which is present in the blood.

10 Foods That'll Keep You Healthy This Summer

STDs or STIs are usually transmitted from one person to another through body fluids while being in a physical relationship. Herpes, Chlamydia, HIV and gonorrhea are some of the common STDs you may be susceptible to. These diseases are extremely unpleasant and usually cause long term health issues. Sometimes they might even be fatal. Here are a few ways you could use to prevent yourself from getting affected with STDs:

    Abstinence: The best and most certain way of preventing STDs is practicing abstinence. Although abstinence from any type of sexual activities including oral, vaginal or anal sex is a surefire method of prevention, it is not a very realistic method to do so. If you don't want to practice abstinence, make sure you educate yourself about other prevention methods.
    Single partner: Practicing monogamy in terms of sex is the safest kind of sexual activity. Make sure both you and your partner get tested for any STD. If you and your partner are not suffering from any STD and you both agree to practice monogamy with each other, then you automatically cut down on the risk of suffering from STDs.
    Talk: Talk to your sexual partner about his/her sexual health. Inform him/her about yours as well. Avoid having sex with someone who does not inform you with his or her sexual health information.
    Avoid taking drugs or alcohol: Try not to get drunk or take drugs before having sex. They reduce inhibitions which actually tend to make you reckless. You tend to become more adventurous and do not keep the sexual hygiene in mind at that time. Using a condom in the influence of alcohol and drugs can also result in a condom failure. Be sober enough before you have sex.
    Do not indulge with a person with symptoms: If someone shows symptoms of suffering from any kind of STD, do not indulge in any sexual activity with him or her. Refrain from having sex with him or her until he or she is treated by a doctor.
    Take precaution: Use different forms of protection while having sex to prevent pregnancy as well as STDs. But you have to realize the fact that these forms of protection are not full proof and always have a slight percentage of risk embedded in them.

Be extremely careful before you indulge in any type of sexual activity with anyone. After all, your health is in your hands.
