Colorectal cancer is otherwise known as cancer of the colon or the rectum. This can affect both men and women with age being a major risk factor. Majority of such cancers are seen to occur after age of 50 years.

Type: colorectal cancers can present as one of the following types: 

Adenocarcinomas are the most common type of colorectal cancers. These cancers begin in the cells making mucous and other fluids. Certain colorectal cancers begin as adenomatous polyps (adenomas) that turn cancerous over a period of time. This is precisely why the adenomas are regarded as pre-cancerous or pre-malignant.

Gastrointestinal (GI) carcinoid tumors, GI stromal tumors, primary colorectal lymphoma, leiomyosarcoma, melanoma & squamous cell carcinoma are certain other colorectal cancers

Carcinoid tumors: start in specialized cells that produce hormones, in the intestine.

GI Stromal tumors: start in the interstitial cells of Cajal (ICC), in the wall of the colon.

Lymphomas: start typically in the lymph nodes but they may also start in colon or rectum.

Sarcomas: can start in the muscle and the connective tissue in the walls of the colon and rectum.

Gender: it affects both male and female populace.

Etiology: mostly, the factors that are associated with increased risk of colorectal cancer include the following  

Age exceeding 50 years.

Racial & ethnic background such as African Americans, in the USA, are known to have the highest incidence of colorectal cancer, and mortality rates.

Low fibre and high fat diet. Excessive consumption of red meat (e.g. goat meat, beef, pork, lamb, or liver), processed meats, butter, refined grains, sweets, sugary drinks etc all can increase the risk of colorectal cancer.

Personal history of inflammatory bowel disease (IBD) (e.g. ulcerative colitis), Crohn s disease, adenomatous colorectal polyps, colorectal cancer etc all.

Family history of colorectal cancer or adenomatous polyps etc all.

Inherited syndromes such as familial adenomatous polyposis (FAP) and Lynch syndrome (hereditary non-polyposis colon cancer or HNPCC).

Sedentary lifestyle/ associated Obesity.

Type 2 diabetes.

Tobacco and alcohol abuse.

Features or symptoms can vary from person to person depending on the size and location of the tumour. Following are the signs & symptoms mainly -

Changes in bowel habits, diarrhea or constipation or an alternating diarrhea and constipation.

Occult/ blood in the stool, and 

Problems related to blood loss (e.g. anemia, weakness, fatigue, intolerance to exercise, shortness of breath, increased heart rate, chest pain etc all),

Abdominal discomfort (frequent gas/ flatulence, bloating, fullness, cramps, and pain), vomiting etc.

Unexplained weight loss,

Pain with bowel movement,

Feeling that bowel does not empty completely,

Stools are narrower than usual.

Diagnosis: Following are the diagnostics employed. Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for accurate diagnosis.
Blood: fecal occult blood test, Carcinoembryonic Antigen (CEA) assay values are raised, Hb/ RBC counts may be low.
Imaging: Colonoscopy, Endorectal Scan/ CT Scan followed by Biopsy clinches the diagnosis and the nature of the disease.
Apart from the above-mentioned barium enema X-Ray, USG, Chest X-ray, PET CT scan etc all help detect metastasis, if any. An increase in level of the serum tumor marker  CEA  is indicative of metastatic spread/ proliferation that can be ascertained through a PET CT scan.
Treatment: Conventional treatment includes surgery, radiation and chemotherapy as contextually appropriate. Simultaneously, an adjunctive/ integrative naturopathic treatment with suitable complementary & alternative medicines (CAM)/ therapies too can help improve clinical outcomes and facilitate recovery as feasible contextually.
Prognosis: preventive measures, earlier diagnosis and right early treatment is key for better prognosis and efficient/ effective therapeutic management. Usually, the chances of cure for an early stage cancer are more. Above-mentioned apart, recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all too.

Prevention: rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for prevention or reducing the risks of colorectal cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Apart from the generic preventive measures as mentioned above, certain pre-malignant conditions, of which adenomas are the most common, can be successfully treated with complementary and alternative medicines too.

Colorectal Cancer - In a Nutshell!

If you are experiencing pain in the muscles and joints, an enhanced craving for salt, symptoms of low glucose in the blood or low blood pressure, you could be suffering from adrenal insufficiency (AI). The outer layer or cortex of our adrenal gland produces three forms of steroid hormones. In adrenal insufficiency, the cortex fails to produce enough steroid hormones. Some people do not know that they have been affected with adrenal insufficiency until they experience a sudden worsening of symptoms. This is called an adrenal crisis.

Causes
The different types of adrenal insufficiencies occur because of different reasons. Primary AI is commonly caused by autoimmune diseases in which our body s defence system destroys the body s tissues. Bleeding in glands, genetic diseases and infections are other likely causes.

Secondary AI occurs because of problems with the pituitary gland. The pituitary gland produces a hormone named adrenocorticotrophic hormone (ACTH) because of which the adrenal glands produce cortisol. In the case of secondary AI, the pituitary glands stop sending ACTH to the adrenal glands, and cortisol is hence not produced. This may occur by taking certain prescribed medicines.

Diagnosis
A patients s medical symptoms and medical history are observed. The blood levels of cortisol, sodium, potassium and glucose are checked for the detection of AI. The adrenal glands and the pituitary gland are observed by imaging tests. X-rays, ultrasound, and CT and MRI scans may be required.

Treatment
The treatment of adrenal insufficiency aims at ensuring proper levels of hormones in the body. You may require regular replacement of hormones for life. You have to take glucocorticoids for replacing the cortisol which your body does not provide anymore. Mineralocorticoids should be taken when the body does not produce aldosterone. Extra glucocorticoids may be required during times of intense stress such as a surgery or serious health conditions.

Glucocorticoid helps the body in coping with stress, injury and illness. It helps in the regulation of blood glucose levels and blood pressure levels. It performs the function of cortisol.
Mineralocorticoid helps in maintaining a proper balance of water and salt in our body. This is actually carried out by aldosterone.
Adrenal androgens, which are weak male sex hormones, present in both men and women, help in the regulation of pubic and armpit hair growth in women.
If you experience any symptoms of adrenal insufficiency, it is recommended that you visit a doctor immediately. Early diagnosis will enable early treatment, which is beneficial for you.

Ovarian cysts and fertility: Is there a connection?

Having a child is one of the most profound experiences in a woman s life. The joy of being a mother and welcoming a new life is unparalleled. In the midst of such expectation, an inability to conceive can take a serious toll on any woman s health. The mental scars from such an event can never be obliterated.

This does not mean you should give up. Consult a doctor to find the cause and rectify it. With advances in medical science and technologies like IVF in the market, no fertility challenge is insurmountable.

One of the most common cause of infertility is ovarian cysts. According to research conducted by the American Society For Reproductive Medicine, ovarian cysts resulting in ovulation abnormality and infertility has been recorded among 25% of women.

There are two types of cysts that are produced as byproducts of ovulation-

1. Follicular Cysts which does not break open to release the eggs. Rather the follicle stays as a whole while the cyst continues to grow.

2. Corpus Cysts or luteal cysts is a condition when after the egg has bronek free, the follicles seal itself rather than shrinking and the fluid builds up inside.

Causes-

Ovarian cysts are mainly caused due to hormonal imbalance, abnormal cell growth where the cells overgrow and develop into cysts, pelvic infections that spread to the ovaries and fallopian tubes and causes severe harm to them, and endometriosis when the tissue attaches to an ovary and forms cell growth.

Which ovarian cyst affects fertility?

Ovarian cysts that generate complications during pregnancy include-

1. Endometriomas - This is the condition when the tissues lining your uterus or endometrium grows outside the uterus or the fallopian tubes and is largely associated with fertility problems. Endometriomas can differ in sizes from the range of less than an inch to over 6 inches. They are filled with dark coloured blood.

Some studies have demonstrated that women suffering from mild endometriosis develop a lower (2%-4%) chance of getting pregnant each month when compared to women who are healthy and have a 15%-20% chance. Another research states that 40% of unexplained infertility results from endometriosis through anatomical distortion or inflammation.

2. Polycystic Ovary Syndrome - PCOS is the condition where small cysts form inside your ovaries which prompts irregular periods, excessive stomach cramps and large hormonal imbalance. Connected to immature ovaries, they do not assist in ovulation and thus produces complications infertility. The immature follicles with an immature egg cause the ovary to be politic.

This chronic lack of ovulation also alters the hormonal levels in your body that assists in ovulation. Women with PCOS develop high levels of androgen or male hormones in your body, which gets converted to estrogen. As a result, they do not ovulate.

Does the treatment of ovarian cysts also affect fertility?

This usually depends on the kind of treatment you receive. Hormonal birth control doesn t have a long-term effect on fertility. Although surgeries can invariably damage some healthy eggs inside your body, the doctors recommend that the ovaries be removed before you have more complications. However, in both the situations, the egg count in your body decreases significantly.

Ovarian Cysts & Fertility - Is There A Connection?

Being overweight is becoming a common sight. However, opting for bariatric surgery is not the first option for everyone who is obese. Also to remember is that morbid obesity is not an isolated condition. It affects a person s overall physical and mental health in various ways, and therefore bariatric surgery becomes an option only as a last resort. 

Some defining criteria for this surgery would be:

A male who is at least 100 pounds overweight for his height or a female who is at least 80 pounds overweight for her height. This puts them at a body mass index (BMI) of more than 40.
If the BMI is in the range of 35 to 39 and if there are significant health issues like metabolic syndrome, then bariatric surgery can be done. For BMI less than 35, other conservative measures are usually tried before resorting to a surgical approach.
Most people with BMI in the range of 35 and above will have health issues like sleep apnoea, heart disease, lipid disorders, and metabolic syndrome.
Conservative measures to lose weight including diet changes and exercise have failed to produce any desired results.
The person, in addition to physical health, should also be emotionally strong to undergo the demands of bariatric surgery. There are changes involving almost all body systems including digestive, respiratory, cardiac, and musculoskeletal, and so the person needs to be prepared for a lifestyle change.
Strict lifestyle changes including diet and exercise are required, so the person needs to be counseled and convinced about these. A person who can see the long-term benefits will be willing to take the effort.
It is also essential that the person has a strong social support system. For immediate post-op care when skin flaps need to be managed, and for long-term emotional support to manage emotional issues, it works wonders if there is a strong social network. The results are usually better in such people.
A person s overall health would be screened to make sure the lab tests are well within acceptable limits before surgery. It would be unreasonable to get these numbers within limits, if they are way too beyond acceptable limits.
Not the least consideration, but bariatric surgery is an expensive affair. It requires not just surgical costs, but also post-op costs. The good thing, however, is that overall healthcare costs would come down, once the results are visible.
Identifying the right candidate for a bariatric surgery is very essential, as doing this extensive surgical approach on an unsuitable candidate would be a failure.

Bariatric Surgery - Who Is Eligible For The Same?

The kidneys are two small organs located in the abdomen. The main function performed by these organs is filtering of the blood. Kidneys help remove waste from the blood which they turn into urine so that it may be excreted from the body. In doing this they also help regulate blood pressure, maintain the production of red blood cells, and sustain the electrolyte balance. When the kidneys do not function properly, the results could be fatal. 

Hence, it is important to be able to recognize the early signs and symptoms of Kidney failure.

Tiredness: A decrease in kidney functioning can cause toxins to build up in the body and blood. This can make a person feel more tired than usual and keep them from concentrating on simple tasks. Kidney failure is also associated with anemia which can also contribute to fatigue.
Trouble sleeping: Chronic kidney disease has been linked to obesity and sleep apnea. Both these conditions can make it difficult for a person to fall asleep and stay asleep. The buildup of toxins in the blood can also contribute to insomnia.
Dry skin: The skin is one of the first organs to show signs of internal organ failure. Thus, when the kidneys stop functioning as well as they are supposed to, the skin turns dry and itchy. This is because the production of red blood cells is reduced and the amount of minerals or nutrients in the body is unbalanced.
Increased urge to urinate: An increased urge to urinate frequently especially at night could be a sign of kidney disease. This may also be a sign of a urinary infection.
Blood in the urine: Urine should ideally be clear and pale yellow in color. Seeing blood mixed with urine should never be ignored. This is a sign that the kidneys have been damaged and blood is leaking into the urine. It could also be a sign of kidney stones, an infection, or a tumor in the kidney.
Foamy urine: Excessive foam in the urine that does not go away even after flushing could be a sign of protein in the urine. This foam may look similar to a beaten egg white as it is produced by albumin; the same protein present in eggs.
Swollen ankles: Swollen ankles are a sign of sodium retention. This is caused by the improper filtration of blood by the kidneys. The patient may also notice his or her feet getting swollen.

Kidney Failure - Recognising The Early Signs!

If the blood flow between left ventricle and aorta is obstructed, it is known as Aortic Stenosis.
Aortic stenosis can occur in newborn, infants, children and adolescents. It is more common among boys than in girls.
Mild cases of this disorder do not need treatment. However, if a child has a severe case of aortic stenosis, then it requires treatment.

Aortic stenosis: Causes-

Blockage in the valve, mainly in the form of bicuspid valve stenosis (Aortic valve stenosis)
Muscular/fibrinous obstruction beneath the aortic valve (Subaortic stenosis)
Narrowing above the aortic valve in aorta itself (Supravalvular aortic stenosis)
Aortic valves regulate blood flow to the body parts. When aortic valve opens, it allows blood to go forward then it closed down so that blood will not come back to left ventricle.
However, if there is a problem with the aortic valve, it cannot open entirely and that restricts the passage of blood. The heart has to work extra hard to ensure that the entire volume of blood flow through the faulty valve.

Sometimes babies are born with deformed aortic valve in the form of bicuspid aortic valve that is prone for obstruction as compared to normal trileaflet aortic valve.

Aortic Stenosis: Symptoms-

Symptoms due to aortic stenos is depends on age of the child and its severity.
If occurs in newborn babies, it is generally severe in intensity and babies are generally in shock like state due to low cardiac output.
Infants are generally tired easily during feeding.
Children show signs of easy fatigue, chest pain, loss of consciousness and in late stages with shortness of breath.
Diagnosis of Aortic Stenosis-

Pre-natal testing like a fetal echocardiogram can reveal aortic stenosis if moderate to severe in intensity. That is why as soon as the baby is born, treatment is initiated.
Even if the child was not born with a problematic valve, this condition can arise a few years later.
For diagnosing this disease pediatric echocardiogram by pediatric cardiologist needs to be done from the chest of the child
Treatment of Aortic Stenosis-

If aortic stenosis is mild to moderate in intensity then we need to do follow-up of the child at regular intervals.
However, in severe aortic stenosis, treatment needs to be done
In valvular aortic stenosis, treatment of choice is by doing ballooning of aortic valve (Balloon aortic valvuloplasty, BAV) in any age group.

Balloon Aortic Valvuloplasty - This is not open-heart surgery. It is done in cardiac cath lab under fluoroscopic guidance by using vessels in thigh. We cross the valve with wire and catheters and we inflate a balloon across the stenosed aortic valve.

Open heart surgery: In subvalvular and supravalvular aortic stenosis, treatment is by open heart surgery.

Valve Replacement - An artificial valve or a donor valve is surgically attached at aortic valve location when valve is not amenable for ballooning. It is generally done in adolescent or adult patients.
Parents need to be alert and attentive to any physical discomfort that their child is suffering because that could be a symptom of aortic stenosis. The right treatment at the right time is necessary whenever required.
