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.

Aortic Stenosis - All You Must Know About It!

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!

Hernia surgery is performed for the correction of a hernia which refers to the bulging of internal organs or tissues through an abnormal opening. It is easy to detect hernia through any pain or discomfort while lifting heavy objects, cough and strain during urination or bowel movements or during prolonged standing or sitting. It can be found in both men and women. The Hernia can be congenital or can be developed over a period of time. If it doesn t get better over time and also does not go away by itself, then surgery becomes the only option.

Types of Surgery
There are two types of surgery for hernia treatment. One is the conventional open method, which requires an incision in the skin directly over the hernia. The other one is the Laparoscopic hernia repair in which surgery is performed using a small telescope known as a laparoscope. In this type of surgery minimal invasions are made and the hernia is repaired with only small incisions adjacent to the hernia. Most hernia operations are performed on an outpatient basis, which means that you can go home the very same day.

Tips for early recovery

    Wear comfortable clothing with expandable waistbands.
    Keep yourself active by moving around as much as you can as it increases circulation, which further speeds up healing.
    Eat a diet rich in fibre, fresh fruits and vegetables.
    Drink lots of water and other fluids to avoid constipation.
    Do not lift any objects even if it is very light as it can bring back pain.
    Do not to pick up things from the floor as it will be difficult to bend.
    Hold a pillow against your stomach while sneezing or coughing to lessen the pain.
    Use stool softener for a few days before and after surgery to help you with your bowel movements.
    Avoid driving till the time you feel any pain and as long as you are taking narcotic pain medicines.
    Band-Aids which cover the incisions should be changed as and when needed.
    Refrain yourself from intercourse as it can be painful.
    Check with your doctor when to take a shower so as not to hurt your incisions, and make sure to gently dry your incisions and replace the Band-Aids after taking a shower.
    Do not consume any alcoholic drinks for at least 24 hours.

The tips mentioned above will definitely provide help to cope up with post surgery blues. However, in case of fever, excessive sweating, difficulty in urinating, bleeding or any prolonged pain consult your doctor immediately.

Hernia Surgery - 13 Tips to Help You Recover from it

Formation of blood clots in the arteries of the lungs, heart or legs can actually kill a person. In such a case, the immediate medical action is necessary and the only way to deal with blood clots is thrombolysis.
Thrombolysis or thrombolytic therapy is a medical process that dissolves blood clots and facilitates blood flow to all parts of the body. Thus, it protects tissues and muscles from damage.

What are the causes of blood clots in the body?

  Poor blood circulation
  Conditions such as Deep Venous Thrombosis and atrial fibrillation
  Blood clots can also be formed because of dialysis catheters and by-pass grafts

How can you tell if you have blood clots?

  Swelling in one or more legs
  Cramp and tenderness in the legs
  Breathing trouble might indicate that blood clots have travelled to the lungs
  Sweating and frequent chest pain may suggest that blood clots have travelled to the heart

How is Thrombolysis performed?

Thrombolytic drugs are injected into the body intravenously. They make their way to where the blood clots exist and dissolve them. If there is a medical emergency, the drugs are delivered to the exact location of the blood clots and immediately start dissolving them. Another method is inserting a device into the blood clot infested region to break the clots up. The drugs which on entering the body dissolve blood clots are called thrombolytics. There are many varieties of thrombolytics such as the following-

  Streptokinase - It is a kind of enzyme. It is used when a person has just suffered a heart attack or pulmonary embolism. Doctors do not usually prescribe the second usage of this drug. It is injected into a vein and can be administered to pregnant women.

  Tenecteplase - Also an enzyme, it is a plasminogen activator. When it binds to the surface of the blood clot, it makes the clot degenerate.

  Reteplase - It is actually extracted from E-Coli. It is a sterile intravenous bolus injection

The leading cause of heart attacks and ischemic heart disorder is the formation of blood clots in the arteries that connect the heart and the brain. Thrombolysis is often employed as an emergency treatment for this purpose. Thrombolysis is also effective against blood clots formed in the lungs (which lead to acute pulmonary embolism). Sometimes blood clots are formed in the legs, upper extremities of the body, the pelvic region (deep vein thrombosis). These clots may travel to the lungs and heart.

Consult your doctor before undergoing the treatment.

Thrombolysis - Causes, Symptoms & Treatment Of It!

This surgery involves the removal of Gallbladder, which is a pear-shaped organ that lies right beneath the right side of the liver. The main function of the gallbladder is to collect and concentrate bile, which is a digestive juice produced by liver after eating, aiding digestion. The most common disorder of the digestive system is presence of Gallstones, which are the stones made up of a mixture consisting of cholesterol, bile pigment and calcium salts.

These Gallstones don t cause any problems in most cases. But prompt treatment is required if stones block ducts and cause infections and inflammation in the pancreas. This may lead to removal of the gallbladder through a surgery, known as cholecystectomy, which further includes techniques such as laparoscopic (keyhole) cholecystectomy or open surgery.
Although it is a less vital organ, the body can cope up even after removal.

Procedure of surgery:

    The surgery involves removal of gallbladder and gallstones through several incisions in the abdomen. In order to see clearly, the surgeon inflates the abdomen with air or carbon dioxide.
    A lighted scope attached to a video camera is inserted into one incision near the belly button. The video monitor is used as a guide for inserting other surgical instruments into the other incisions to remove the gallbladder.
    Intraoperative cholangiography is the X-ray procedure which shows the anatomy of bile ducts. This is done before the surgeon removes the gallbladder.
    Bile flows from the liver through the common bile duct after the surgery into the small intestine. As the gallbladder has been removed, the gallbladder can no longer store bile between meals but has no effect or little effect on digestion.
    In case of open surgery, the surgeon reaches the gallbladder through a large, single incision in the abdominal wall.

Complications after gallbladder surgery:
This surgery carries some degree of risk like any other surgery. Complications such as internal bleeding, infection, injury to nearby digestive organs, injury to the bile duct and injury to blood vessels.

Types of gallstones:
There are three main types of gallstones. They are
1. Mixed stones: They are made up of cholesterol and salts. They tend to develop in batches.
2. Cholesterol stones: Mainly made of cholesterol, which is crucial to many metabolic processes. They can grow large enough to block the bile ducts.
3. Pigment stones: The colour of bile is greenish-brown, due to some particular pigments.

Medical factors to consider before cholecystectomy:
The most important factor is a consideration of your medical history. This is because the pre-existing conditions influence decisions on surgery and anaesthetic and information about any bad reactions or side effects from any medications would be helpful for surgery.

Self-care after the surgery:
Taking rest is the most important thing after surgery. Avoid things such as heavy lifting and physical exertion. The usual recovery period after the surgery is one week. 

Gallstone Surgery - Things You Should Know About It 

Screening for cancer of the colon or large intestine and rectum is a proven way of saving a person from the impacts of colorectal diseases. This is partly because colon cancer is something that can be prevented if detected at an early stage and the polyps which may advance to cancer are removed properly. Thus if you are turning 50 soon, be prepared to present yourself for a screening colonoscopy that will help you ensure good health and well-being. It may sound uncanny, but do you know that 50,000 people across the world die from colorectal cancer every year, and it is ranked second in terms of cancer-centric deaths.

Understanding the importance of having colonoscopy
You may wonder how a painful, invasive, embarrassing, uncomfortable and time-consuming health test may be called a present. There are reasons enough. A screening colonoscopy is able to expose a cancerous tumour that's presently under way and cast light on the chances and risk factors that may precede it. When you choose to intervene early, you have the power to nip those risks at their budding stage, much before those malicious cells become malignant.

Spreading of the colorectal cancer
Your large intestine is really a big and last organ of the gastrointestinal system where the small intestine discontinues. Its primary function is to remove the water out of the leftover solids of digestion and get rid of them in the form of stool. Cancer may start to develop anywhere within the tube that expands 5 feet long and squares the vacant area of the abdomen. The large intestine expands up towards the right side, i.e. the ascending colon and then turns left through the liver, i.e., the transverse colon, bending down right at the spleen on its left, i.e. descending colon and loops to the middle, i.e., the sigmoid colon before it runs across the rectum and ends at the anus.

People who need a colonoscopy
To simplify matters, it can be said that all adults are at a potential risk of the colorectal cancer, including those people who lead a healthy life. But some people are at a higher risk. Those individuals have a specific gene mutation that predisposes them to develop into numerous polyps. The risk is also high with people who are first-degree relatives of a person diagnosed with cancer before the age of 50. People with Ulcerative colitis, various types of inflammatory bowel diseases and Crohn's disease are also at a higher risk.

Colorectal cancer is a serious ailment and screening colonoscopy is a feasible means of detecting any polyps that may be cancerous in the future. Speak with a reputed gastroenterologist today to stay ahead of the disease.
