A polyp is a cauliflower-like growth on the skin or the mucosal surface. Colon is the medical term for the larger intestine and the rectum. A growth on the mucosal surface of this part of the intestine is known as a colon polyp. Although not visible, colon polyps is present with symptoms, which can lead to their diagnosis. The main cause for concern is that some colon polyps can turn into colorectal cancer, which is the third largest cancer in America.

Types: There are two main types of polyps

Hyperplastic or inflammatory: These are benign growths and do not carry the risk of developing into cancer.
Adenomas: These carry the risk of turning into cancer, and so early detection and intervention is essential.
Though not all polyps develop into tumors, yet all tumors develop from a polyp. There is a strong genetic component, which makes it worse. Someone with inflammatory bowel disease or Crohn s disease is also at a higher risk of mucosal inflammation, which can induce dysplasia and then polyps.

Risk factors:

Family history
Inflammatory bowel disease
Obesity
Diet rich in processed meat and red meat
Smoking
Lack of physical activity
Type 2 diabetes
Being male, being African American
Symptoms: Though often silent, some symptoms which also appear only after the polyp has grown considerably include:

Bleeding with stools   often small amounts intermittently, which is occult bleeding, not visible though
Altered bowel habits (constipation, diarrhea)
Abdominal pain and discomfort
Unexplained weight loss
Anemia (due to blood loss)
Diagnosis: If a person is at risk from medical history and has the above symptoms, then the following are done:

Sigmoidoscopy Viewing the colon and rectum to see if there are any polyps. A biopsy may also be taken to confirm cancerous growth.
Colonoscopy The entire colon is viewed to rule out polyps in other areas of the colon.
CT scan of the abdomen which is non-invasive and can be used as the first step.
Treatment:

If a polyp is diagnosed, then it needs to be removed.
If it turns out cancerous, then detailed evaluation should be done to rule out spread to other areas. Additionally, chemotherapy and radiotherapy may be required to completely eliminate the tumor and contain it.
The surgical removal of the tumor would be planned depending on the stage of the tumor.
Adapting a healthy lifestyle is very essential to managing polyps and preventing cancer. Quitting smoking, managing weight, eating healthy, and being physically active are some ways to prevent colorectal cancer.
Repeat colonoscopy needs to be done to ensure these are not recurrent.

Colon Polyps - What Are The Available Treatment Options?

Renal Tubular Acidosis is a medical condition. When the kidney is unable to acidify urine, it leads to the accumulation of acid in the body. Usually, when blood is filtered by the kidney, it passes through the tubules of the nephrons (the functional unit of the kidney).

Before it flows into the bladder from the kidney, the urine undergoes an exchange of salts, acids and other solutes. Renal tubular acidosis results in the formation of excessive amounts of acid because the kidneys cannot drain them. This may happen because the kidneys cannot reabsorb the alkaline bicarbonate ions from the urine in the early segment of the nephron or because of inadequate production of acidic hydrogen ions in the latter half of the nephron.

Renal Tubular Acidosis is simply associated with abnormal urinary acidification. Other functions of the kidneys remain unimpaired.
There are several different types of renal tubular acidosis-

  Distal Renal Tubular Acidosis (RTA)
This is the most fundamental form of RTA. It is characterized when the hydrogen ions are not secreted into the lumen of the nephron by the alpha-intercalated cells of the medullary collective duct of the distal nephron. When this happens the pH of urine cannot be brought down below 5.3. Renal excretion is inhibited and hydrogen ions are not eliminated which leads to academia. At the same time, Potassium ions cannot be absorbed by the cell which leads to hypokalemia. The end result is protein retention and potassium excretion. Distal RTA can lead to the urinary stone formation, calcium deposits in the kidney, rickets and osteomalacia and Sjogren s syndrome.

  Proximal RTA
When proximal tubular cells reabsorb 85% of filtered bicarbonates and 60% of filtered sodium from the urine, then this again leads to academia. The distal intercalated cells, however, function normally and so the academia is not as severe as in case of Distal RTA. The alpha-intercalated cells can acidify urine to a pH of 5.3 or less because they produce hydrogen ions. Proximal RTA is also associated with Fanconi Syndrome which is characterized by aminoaciduria, uricosuria, glucosuria, and tubular proteinuria.

  Combined distal and proximal RTA
Inherited carbonic anhydrase II deficit leads to combined distal and proximal RTA. This is accompanied by osteopetrosis, cerebral calcification, and renal tubular acidosis. Cases of combined distal and proximal RTA are very rare.

How is RTA understood?
The following steps are applied to analyze Renal Tubular Acidosis-
  Determining the anion gap in acidosis. The normal Anion Gap is 8-12 (4-6 mEq/L)
  Separating the renal from the extrarenal causes of normal anion gap acidosis
  Classifying the types of RTA
  If it is distal RTA, further tests will be necessary to support the diagnosis

How is RTA diagnosed?
Three types of tests can reveal if a person is affected by Renal Tubular Acidosis-
  Urine test
  Acid load test
  Physical examination

Treatment of RTA-
Doctors prescribe either or both of the following two types of therapies-

  Alkali therapy- The pH level of urine is restored and electrolytes are balanced
  Vitamin D supplements- If RTA leads to bone deformities or rickets, your doctor will prescribe vitamin supplements to strengthen your bones.

Timely diagnosis can prevent the effects of Renal tubular Acidosis from becoming compounded. With the right medication, a person can lead a healthy normal life.

What Should You Know About Renal Tubular Acidosis?

Bariatric surgery is unlike other surgeries, as its effects are not instant but gradual and are seen over the months. Like any other surgery, it is not without complication. But again unlike all other surgeries, the complication rate can be negligible if a strict protocol is followed. Moreover, the factors like technology advancements, development in the field of advanced laparoscopy, enhanced skillset of the bariatric surgeon, dedicated management of bariatric and metabolic surgeries by bariatric surgeons, play a vital role in the reduction of complication rate which eventually results in safe surgery.

As the procedure is done laparoscopically, the pain is just for a day and is minimally managed by analgesics.

The fear of increasing incidence of incisional hernias while operating an obese patient is so negligible or nil, as the procedure is performed through tiny key holes and all precautions are taken to suture the sheath through which the ports are put to perform the surgery.

Reduced hospital stay and early resuming to work is one of the biggest benefits of this laparoscopic bariatric procedure.

Sometimes, problems that may be faced are:- 

Post-operative bleeding: Normally, this a nearly bloodless surgery involving 5 to 10ml loss of blood. However bleeding from the staple edges is known, but this can be managed well by the surgeon, by choosing the right size of the cartridge as well the right technique of application of the cartridge.

Dehydration: We are normally accustomed to drinking water at long intervals (a few hours) as we can consume nearly 200 to 400ml at one go. Following bariatric surgery, gulping or drinking water in one go is not possible in the first 2 to 4 weeks, due to reduced capacity of the gastric pouch. Hence, care needs to be taken to drink small quantities of water at frequent intervals to avoid dehydration. This is possible only if the patient is counselled about this prior to surgery and is fully aware of this. Also, the patient needs to be given good and clear post operative instructions regarding the quantity and frequency of liquid consumption, not forgetting the type of liquids. Coffee taken frequently could be another cause for dehydration. Family members and colleagues and friends at work play a major role in reminding tthe patient about consuming water frequently. Special care needs to be taken in people who are not accustomed to consuming adequate quantities of water prior to surgery as a general habit.

Vomiting/Fullness/ Discomfort/Indigestion: Following bariatric surgery, soft food is introduced in the diet in the third week, after the first 2 weeks of taking liquids. Due to the reduced capacity of the gastric pouch, the morsel size is significantly reduced and one has to chew the morsel well and eat slowly, giving a gap of 40 to 50 seconds between the morsels. This prevents distension or overdistension of the gastric pouch and thus avoids vomiting. This again requires good counselling prior to the surgery and on the follow up visit too before stating soft food. There is a subjective difference when we say small morsels and we cannot reach a standardization as the morsels size of each individual varies prior to the surgery itself. The best way to avoid this confusion is to make the person have the first soft food meal before you where in you can physically show the way food is expected to be eaten. However, by mistake, there is a chance that one can have a regular sized morsel as over years one is used to eating in that manner. If this happens, the person will vomit , and this will be a reminder to gauge the morsel size the next time the person eats. Following the vomiting, there could be a burning sensation in the stomach which will subside afer taking an antacid. If one follows the instructions of small morsel size, chewing properly and eating slowly, there is no chance that there will be vomiting. Another reason for vomiting could be keeping the stomach empty for a longer duration or having sicy food on an empty stomach. Avoid nuts, seeds, fried foods and processed foods. Very rarely vomiting could be due to reduced size of the joint between the gastric pouch and the small intestine. This could require an Endoscopy and necessary treatment.

Vitamin and mineral deficiency: It is seen that many of the obese patients are seen to have vitamin B12, vitamin D, iron and protein deficiencies in their blood tests that are done prior to surgery. With the significant reduction in the amount of food consumed after bariatric surgery, the existing deficiencies are bound to increase. Hence, it is necessary to do these tests, before surgery and rectify the deficit prior to the surgery.  

Gall bladder stones: Significant weight loss which is consistant over a short duration could lead to the formation of gall bladder stones, be it with or with out surgery in a small percentage of patients. To avoid this there are two schools of thought, one is have a prophylactic removal of the gall bladder along with the bariatric surgery and another is to put the patient on ursodeoxycholic acid (a tablet) for the first few months after surgery during which there is significant weight loss.

Skin sagging: In the morbidly obese, when the skin is overstretched beyond a certain point, it tends to sag once significant weight is lost. This sagging is influenced by a number of factors like age of the patient, the BMI, pre existing sagging, pre-existing muscle tone and protein supplements taken during weight loss and exercises done during the weight loss period. Skin sagging is less if the age is less than 45, BMI less than 45, good protein intake during weight loss and good toning exercises done during the weight loss period.

Hairfall: Significant weight loss either by diet and exercise, aerobics, bariatric surgery, will entail hair loss. But this can be minimised to a greater extent by ensuring good protein intake during the weight loss period and adequate supplements in terms of vitamins and minerals.

Dumping syndrome: With a reduced size of the stomach, the food moves from the stomach into the smaller intestine much faster. This causes the pancreas to release excessive amount of insulin, leading to very low blood sugar levels , producing various symptoms like abdominal cramps, bloating, diarrhoea, sweating, dizziness, nausea, weakness, and anxiety. This is managed by eating less amount of sugars and fats and spacing out the meals through the day, having four to five small meals compared to  2 to 3 large meals. Having a high protein diet and avoiding liquids during meals is also an option.

Bariatric Surgery - Know Problems Of It!

Menorrhagia is a condition that is marked by heavy menstrual bleeding during the monthly menstrual cycles. Most women have a unique bleeding pattern during that time of the month with the flow going up and down over the first few days. Yet, for many women, the bleeding becomes consistently heavy during all the days of the period, during which the period itself may get extended by a few days. If this pattern continues to occurs, one must get it checked out by a doctor at the earliest. Here are a few ways in which this condition may be treated.

Factors considered during treatment

Before the treatment starts, and during the diagnosis stage, the doctor will take a look at a number of factors so that the correct form of treatment may be prescribed to the patient. To begin with, the doctor will take a complete medical history of the patient, including the family history to ascertain whether or not there may be a genetic problem at play. Further, the future childbearing plans of the patient will also be taken into consideration in such cases so that the treatment method does not hinder such plans. Also, the doctor will also try and understand the effect of the symptoms of this condition before prescribing any particular medication and surgery.

Medication

Iron supplements and non-steroidal anti-inflammatory medicines will be prescribed for the patient to bring down the level of inflammation and restore the production of blood, which will make up for the rapidly flowing blood from the body. This will also prevent the risk of anemia. Oral contraceptives, tranexamic acid, oral progesterone and hormonal therapy can also help in such cases.

Dilation and curettage

This procedure is also known as D&C, and it basically helps in dilation or opening up of the cervix so that the doctor may suction the tissue from the uterine lining. This tissue is usually known to bring about excessive bleeding.

Uterine artery embolisation

This is a procedure which shrinks any existing fibroids that may be the cause behind excessive bleeding. In this procedure, the uterine arteries are blocked and the blood supply to the same is cut off so that the fibroids do not get a chance to grow and cause unnecessary pressure that may lead to excessive bleeding.

Hysterectomy

This is a surgical procedure that removes the cervix as well as the uterus, and is usually the last resort followed by most doctors. In such cases, the doctor will first ascertain whether or not you plan to have any children in the future. Additionally, the ovaries may also be removed if the condition has spread too much to be contained sufficiently.

Ways to Treat Menorrhagia

Radiotherapy is a kind of treatment that kills the cancer cells by using high energy beams. Specialists use radiotherapy to treat a wide range of lung cancer. For early stage lung cancer, the radiotherapy may get rid of the cancer totally. For the small cell lung cancer you may have radiotherapy only. Then again you may have it with another treatment, for example, chemotherapy or surgery.

For small cell lung cancer, radiotherapy is used with or after chemotherapy. Chemotherapy makes the tumor in the lung shrink. You may have radiotherapy to your cerebrum, which tackles any cancer cells that may have spread to the brain. This is called prophylactic cranial illumination (PCI). In case of advanced lung cancer, the treatment contracts the tumor and controls it for a while. It additionally decreases symptoms like shortness of breath.

The types of radiotherapy used for the lungs include:

Outer radiotherapy: This kind of radiotherapy comes from a machine and is administered to the body through an external source. It depends on the kind of cancer and the progression of the same. You may have three radiotherapy sittings every day for around 12 days. This sort of radiotherapy is known as CHART ceaseless hyperfractionated quickened radiotherapy. A few people with small cell lung cancer may have treatment twice a day. If you are getting radiotherapy to control the side effects of lung cancer, you may have a single treatment or day by day medications for up to 3 weeks.



Inner radiotherapy: This is called brachytherapy or endobronchial treatment. This will be administered during a bronchoscopy. The radiation is given through a thin tube that the specialist puts inside your aviation route for a few of minutes. Specialists use this sort of treatment to shrink a tumor that is blocking or pushing your breathing track and making breathing troublesome for you.

These are some of the procedures that take place while you are having lung cancer radiotherapy:

Radiotherapy machines are enormous. The machines are fixed in one position or are sometimes ready to go around your body to give treatment from various angles.
Prior to your first treatment, your radiographers will clarify what you will hear and see. The treatment room normally have docks for you to connect to music players. So you can listen to your own choice of music.
You cannot feel radiotherapy when you really have the treatment. It takes anything from one second to a few minutes. It is essential to lie similarly situated every time, so the radiographers may take a short time to get you prepared.
Once you are in the right position, the staff will allow you to sit in the space for a couple of minutes. They watch you constantly on a closed circuit TV screen. They may request that you hold your breath or take shallow breaths during the treatment.
In case you have a concern or query you can always consult an expert & get answers to your questions!

Radiotherapy For Lung Cancer!

An anorectal abscess is a painful swelling near the anus or in the buttock. The swelling contains pus. 60% anorectal abscesses are superficial and resulting from infection in small anal glands present in between internal and external anal sphincters (intersphincteric space). They are known as a perianal abscess. 30% of anorectal abscesses are deep-seated and results in systemic infection. They are call Ischiorectal abscess. Submucous abscess, pelvirectal abscess and pilonidal abscess developed from versatile cause are comparatively less common. Inadequate and improper management of anorectal abscess may potentially cause complication like fistula formation.


Fast facts on Anorectal abscess-

* Anorectal abscess should be drained at the earliest.
* Conservative medical management almost invariably invites complication like fistula formation.
* Surgical drainage of pus reduces the chance of fistula formation by 50%.


What causes Anorectal abscess?

* Blocked and infected anal glands (cryptoglandular infection).
* Untreated anal fissure that becomes infected.
* Sexually transmitted infections.
* Penetrating injury of the perianal or buttock region.
* Crohn s disease.
* Colon cancer.
* Tuberculosis.



What are the symptoms of Anorectal abscess?

Superficial abscess-

* Constant and throbbing pain that worsens on sitting down.
* Swelling, redness and tenderness of the skin around the anus.
* Discharge of pus.
* Pain is often associated with bowel movement.

Deep abscess-

* All or some of the symptoms of a superficial abscess.
* Fever with chill and rigor.
* General weakness.
* Sometimes fever is the only symptom of the deep abscess.

The anorectal abscess should preferably be explored under general or spinal anesthesia. Medical management often fails and subsequently fistula is formed.
