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.

Treating Skin Cancer with Photodynamic Therapy

Depression is a clinical, mental and emotional condition that may give rise to feelings of hopelessness and chronic sadness. It slows down the way people process everyday activities and leads the patient to a sense of constant gloom and doom. It is a disabling mental condition as per who and may be caused due to reasons like genetics, changes in the balance of hormones, stress, grief, trauma and prolonged, chronic physical ailments.

Symptoms of depression are:

    Sleep irregularity: It relates to either insomnia or oversleeping that is, either you sleep too much or do not sleep at all. This could be because of work or other stress in your personal or professional life.
    Irritation or unnecessarily getting angry: You start losing your temper easily and that too for silly reasons. You think you are losing control.
    Feeling hopeless and sad: The first signal or symptom is the feeling of hopelessness. In this, case the patient loses the hope in everything. They feel like being trapped in some kind of cage, from which they are not able to come out.
    Lack of interest in anything: Everything seems to be of no use or interest, even your daily work. You don't want to do anything; even the things, which you loved to do like your hobbies and passions, which you no longer find interesting.

Here is a comprehensive list of homeopathic medicines which most doctors are likely to recommend for treating depression:

    Sepia: This medicine is beneficial to women suffering from post-partum depression (sadness or emotional conflict after giving birth) and menopause. Feeling of solitude and hopelessness with no energy to continue with life are some common symptoms that can be reduced with Sepia.
    Arsenicum album: This medicine is prescribed to control the symptoms like diarrhea, gastric problems, indigestion which patients often suffer from as a result of intense anxiety. Patients, appropriate for this medicine tend to be fastidious and restless. It is made of white arsenic and should be taken in prescribed potency because an overdose can cause gastroenteritis.

The above mentioned medicines are just some of the medicines, which should only be taken only after consulting your doctor, as causes and symptoms differ for each person.

Can Sleep Irregularity be a Sign of Depression?

The bowel is a very important part of your body within the digestive system as it plays a vital role in the absorption of nutrients and minerals within your body as well as excreting toxic matter. The bowel contains the small bowel or small intestine as well as the large bowel or the large intestine. However, parts of the bowel may be infected or damaged in such a manner that they may need to be removed in order to save further worsening. Thus, the removal of sections of the bowels is known as bowel resection surgery.

How is bowel resection surgery performed?

In this procedure, sections of either the large intestine or the small intestine are removed which have either become diseased, infected or have malignant growths within them. The doctors and surgeons first identify the sections that need to be removed and then perform the surgery wherein a section of the tissue is excised and then two ends of the bowel are stitched together to form a new section of continuous small intestine or large intestine.

Types of bowel resection
There are two types of bowel resection, namely small bowel resection performed on the small intestine and large bowel resection performed on the large intestine. The indications for both of them are mentioned below:
Small Bowel resection: Some of the cases wherein small bowel resection may be required are as follows:

Cancerous or benign polyps or growth
Precancerous growths and polyps
Damage to the small intestine due to injuries
Congenital defects in the small intestine
Blockages in the intestine
Growth of ulcers, bleeding, and infection within the small intestine
Infections within the intestines
Other disorders of the small intestine
Large bowel resection: Large bowel resection is also carried out due to many of the same reasons as mentioned above. However, some of the specific reasons for large bowel resection are mentioned below:

Colon cancer
Diverticulitis, disorder that specifically affects the large intestine
Bowel inflammation or ulcerative colitis
Abnormal twisting of the bowel also known as volvulus
Intestines which slide into another section of the intestine; also known as intussusception
Risks of the bowel resection
Like any other surgery, bowel resection also carries its own risks just as any other form of surgery. Some of the common risks of bowel resection are  

Adverse reaction to anesthesia
Infections
Heart attacks or strokes during the operation
Infections
Excessive bleeding among others
Specific risks for large and small bowel resections are mentioned as follows:

Small bowel resection: Certain common risks include accumulation of pus in the abdomen, internal bleeding within the intestine after surgery, diarrhea, infection of the incision area and the stitched area breaking open among others
Large bowel resection: In this case, tissues protruding through the cut causing an incisional hernia is the most common element of risk. Nearby organs may be damaged as well; scar tissue, problems with the passage of material within the colon among others are some of the other complications.
However, these issues occur rarely and resections are performed very successfully and quite regularly by surgeons.

Bowel Resection Surgery - Facts You Should be Aware of 

What skin differences can you expect when you're pregnant?

During pregnancy, quite a few changes occur inside a woman's body. It is quite common for some of these changes to surface outside. Skin changes are quite common in pregnant women, and pinkish streaks on the stomach and a sudden glow on the face are commonly observed. Although not all women experience the same skin changes, there are some changes which are quite common during pregnancy. Some of them are:

1. Stretch Marks

Stretch marks are the most common and usual skin changes that occur during pregnancy. Nearly 90% of all pregnant women are likely to experience stretch marks. Stretch marks are the reddish streaks that run down the abdomen or breasts of a pregnant woman. Exercising and applying lotions rich in the vitamin can help in preventing such marks.

2. Mask of pregnancy

Melasma, commonly known as the mask of pregnancy, causes dark splotchy spots to appear on your face. Fluctuations in hormonal activities during those nine months can lead to an increase in pigmentation. These spots usually occur on the forehead and cheeks. Nearly 50% of all pregnant women encounter signs of melasma.

3. Pregnancy Glow

During pregnancy, the body produces 50% more blood; hence, there is a greater circulation of blood in the body, and the increased blood flow causes the face to appear brighter. The body also produces a lot of hormones that cause the glands to overwork, which renders the face shiny.

4. Acne

Hormonal fluctuations in the body can cause the oil glands to secrete more oil, which can cause a breakout. In case of pre-existing acne, the condition may heighten and, thus, get more inflamed.

5. Spider and Varicose veins

Increased blood circulation can cause minute, reddish blood vessels to protrude outwards. These veins usually appear on the face, neck, upper chest and arms. Varicose veins refer to the thick, bluish veins that appear on the legs. This happens because the body compensates for the extra blood that flows to your baby.

Abdomen pain or abdominal pain is usually experienced in the area between the chest and the stomach. This kind of pain usually comes as a dull cramp that also produces shooting stabs of pains intermittently, or it may be a localised pain in one side of the stomach. This may also be accompanied by inflammation and other diseases related to organs like intestines, kidneys, pancreas, liver, spleen and stomach. So what are the causes of stomach or abdomen pain? Read on to find out:

Food Poisoning: Food poisoning can be caused due to dirty water or contaminated food. This can give rise to various infections as well as conditions like traveler's diarrhea or loose motions.

Gastro-Intestinal Conditions: GERD or gastroesophageal reflux disease and gastroenteritis, among various others, can also lead to abdomen pain as a symptom along with severe acidity and nausea. Irritable bowel syndrome is another major ailment which can leave you with persistent abdominal pain. 

Generalized Pain: This kind of pain occurs in the overall area all around the stomach and may point at the presence of conditions like Crohn's Disease, a traumatic injury, appendicitis, flu, or even a urinary tract infection. Further, when the gas settles and tightens the stomach due to the inability to pass a motion on a normal, regular basis, this may be termed as constipation. This also leads to abdomen pain. 

Localised Lower Abdomen Pain: Pain that is found specifically in the lower area of the abdomen can be caused due to appendicitis, obstruction or blockage in the intestine or colon, and other ailments. This pain can also be accompanied by nausea and vomiting. 

Localised Upper Abdomen Pain: This kind of pain may emanate due to the presence of gallstones, liver inflammation or hepatitis, pneumonia, or even in the middle of a heart attack.

Localised Centre Abdomen Pain: Pain in the centre part of the stomach or abdomen may be caused due to gastroenteritis, an injury or even the accumulation of waste products in the body, otherwise known as uremia.

Abdomen Pain and Women: For women, such localised pain may be caused due to pelvic inflammatory disease, urinary tract infection, endometriosis, ectopic pregnancy, menstrual cramps which are also called dysmenorrhoea, and fibroids. Miscarriages can also cause pain in this part of the abdomen, for women.

Renal Stones: Renal stones or stone in kidney is one of the most common causes of abdomen pain. The pain caused by kidney stone is such that it can make a patient roll in bed and this pain may radiate to toward the groin as well. Persistent pain and nausea that come with vomiting and finally give rise to blood in the vomit or stool should be checked by the doctor immediately, so as to rule out any serious ailment. Imaging tests, ultrasound and an X-Ray can help in diagnosis.

Abdomen Pain - Knowing The Common Causes Of It!

Ayurveda is something which is very potent and its efficacy has been proven over the years. Arthritis is painful and has the ability to make a person feel pretty much like his or her hands are tied! However, while not much can be done to liberate a person to his or her pre-arthritis level of ease, the issue can be controlled and Ayurveda can really work wonders!

When you prefer an Ayurvedic treatment to help a person who is suffering from arthritis to experience lesser pain in his or her daily life, it is important to correct anything which may be wrong with digestion. This is because digestion, which is not optimal, leads to a situation of a build-up of ama, which is a lethal side effect of low-quality digestion.

It is believed that correcting a person s food intake will reduce the amount of ama one has in their body and as a result of the same, reduce the inflammation and the consequent pain which a patient of arthritis has to put up with on a daily basis.
If a person does not suffer from other lifestyle issues such as diabetes, making the effort to fast in accordance with the guidelines which have been set out as per the Ayurveda knowledge bank can have great benefits for the problems faced due to having arthritis.
The Magic of Ayurveda!

There is a herb known as Guggul, which is quite helpful, especially if a person is diligent about its consumption. This would mean that it be taken by him or her twice a day, along with some warm water. The dosages are small and usually range between 1 to 3 gms.
Ayurveda is a symbol of natural solutions to the health problems of people. As a result, it is only reasonable to expect a lot of the field to be centred on lifestyle habits and more so around food, as it is true, in this case at least, that we are what we eat.
In order to ease the pains of arthritis, it is very important to avoid oily food items and prefer a fruit diet such as apples, papayas and oranges. Tea, coffee and alcohol consumption should be kept to a bare minimum.
Arthritis is something which is frustrating, for sure. But, as long as a person is taking steps in the right direction, the issue will be a lot easier to deal with!
