What is Pancreatitis

Posted by Healthfitline On Tuesday, June 11, 2013
Pancreatitis is the inflammation of a pancreas. A pancreas is a important organ found deep inside behind the stomach and attached by ducts to both small intestines and gall bladder. Its primary purpose it to secrete enzymes that help in digestion and to produce insulin that regulate the blood glucose levels.

Although it is not well known the mechanism that leads to pancreatitis. However, it is believed that pancreatitis can develop from any condition that lead to obstruction of the pancreas, pancreatic duct, cystic duct and common bile duct. Once there is an obstruction, the pancreatic enzyme get trapped inside the pancreas and together with the bile, they initiate an inflammation process, attacking the pancreas (auto-digestion).
 
Risk Factors of Pancreatitis
  • Penetrating peptic ulcers
  • Alcoholism
  • Use of contraceptive pills
  • Neurological problems
  • Kidney failure
  • People who had previous history of kidney transplant.
  • Abdominal defects
  • Biliary disease
  • High cholesterol
  • Thyroid problem
  • Surgical injuries or trauma  
Types of Pancreatitis
There are two different types of pancreatitis: Acute and Chronic
 
Acute Pancreatitis
Acute Pancreatitis occurs suddenly and can range from mild to several, fatal inflammation that does not respond to any treatment. In mild cases, the inflammation is usually confined within the pancreas and characterized by edema with minimal organ dysfunction. The inflammation usually heals within 6 months and rarely causes any other complication.
 
However, severe inflammation can lead to bleeding (pancreatic enzymes damage the local blood vessels), cysts formation and circulatory problems, leading to kidney failure, pulmonary problems or even shock.
 
Chronic Pancreatitis
Chronic pancreatitis is usually diagnosed after an episode of acute pancreatitis or when 80% - 90% of pancreas has already been destroyed. It more common in men between the ages of 40 - 45 years with history of alcoholism or women between the ages of 50 - 55 with previous history of suffering from a gallstone disease.
 
Signs and Symptoms of Pancreatitis
Signs and symptoms of pancreatitis may include; 
  • Abdominal pain - felt at the middle area (epigastrium region), below the sternum and radiates to the back. Pain mostly occurs after eating a heavy meal, a fatty meal, drinking alcohol or when lying on the back. 
  • Pain is not relieved by taking antacid. However, it may be temporary relieved by a knee-chest position (a position in which a person rests on the knees and upper part of the chest).
  • Pain may be followed by an abdominal distention.
  • Malnutrition due to poor food absorption rate (usually chronic cases)
  • Fatty stool (steartorrhea)
  • Nausea and vomiting
  • Fever
  • Decreased bowel sound
  • Jaundice and itchiness
  • Diabetes due to destruction of islet and beta cells 
Severe Pancreatitis
  • Bleeding leading to discoloration of the abdomen and peri-umbilical area (Cullen's sign)
  • Hypovolemic shock
Pancreatitis Diagnosis
The diagnosis of pancreatitis is based on the presenting symptoms and presence of any known risk factor. Tests performed to diagnose pancreatitis may include;
 
  • Pancreatic Function Test - to measure the level of amylase and lipase. In acute cases, it is usually increased 3 times the normal amount within the first 24 hours.
  • Urinary amylase - used to measure the enzymes levels in urine.
  • Blood test - increased white blood cells due to infection.
  • X-ray to study the abdomen and chest.
  • Ultrasound to produce images of the pancreas.
  • CT scans to produce images of the damaged pancreas part.
  • ERCP (endoscopic retrograde cholangiopancreatography) used to rule out pancreatitis caused by gallstone.
Pancreatitis Treatment
Pancreatitis treatment is directed towards preventing possible complications and relieving symptoms. Acute pancreatitis is usually treated with intravenous fluid and medications to relieve pain. In some cases, it may require the patient to be put under intensive care unit for close monitoring and to prevent development of serious complication.
 
Respiratory care and monitoring is also maintained to prevent possible hypoxemia (low oxygen levels inside the blood). Some patient may require supplemental oxygen or intubation using a mechanical ventilator.
 
Other way to treat pancreatitis include;
  • Biliary drainage - to drain bile and establish a pancreatic drainage.
  • Surgical intervention - to relieve pain, establish a drainage, resect or remove a necrotic (dead) part of the pancreas. A small incision about 5- 10 millimeter is usually made into the abdomen. The surgeon or the doctor is then guided by a laparoscope to produce images of the pancreas into the monitor.
Patients are also advised to stop alcohol consumption and other medications that can lead to acute pancreatitis. The doctor also discusses about follow-ups visits to determine whether the pancreatitis is resolving and to assess other problems that may be arising from the inflammation.
 
How to Prevent Pancreatitis
Though the cause of pancreatitis is different on each individual. There are various measures that you can take to minimize the risk of acquiring pancreatitis, such as;
 
  • Avoiding alcohol abuse
  • Eating low fat diet to prevent increase in cholesterol.
  • Use medications as directed by your doctor and avoiding over the counter medications or self medication.
  • Consult medical help as soon as possible whenever you feel unwell.
  • Follow the doctor's advice and maintain all the follow up schedules as indicated by your physician.
  • If you cannot stop drinking alcohol, talk to your doctor or a health care provider about it.

What is Labyrinthitis?

Posted by Healthfitline On Sunday, May 5, 2013
Labyrinthitis is an inflammation or swelling of the inner ear. The most common cause of Labyrinthitis is the viruses. However, it can also occurs as a complication from a bacteria infection such as Otitis Media, when the bacteria spreads from the middle ear to the inner ear.
 
Labyrinthitis Causes and Risk Facts
The following are causes and risk factors that increases your chances of acquiring Labyrinthitis;
 
  • Infection of the middle ear (Otitis Media).
  • Mumps and rubella viral infections
  • Upper respiratory tract viral infections 
  • Herpes Varicella Zoster Virus infection (Ramsay Hunt Syndrome) - a disorder that is characterized by pain and paralysis of the facial nerves.
  • Excessive consumption of alcohol
  • Allergies
  • Stress and smoking
  • Medications - Aspirin 
Labyrinthitis Symptoms
  • Nausea and vomiting
  • Dizziness 
  • Vertigo - lack of balance and a sensation as if you are moving or spinning around. 
  • Ringing (tinnitus) or hearing some voices inside your ears. 
  • Temporary hearing loss that may start with one ear. 
Labyrinthitis Complications 
Possible complications associated with Labyrinthitis include; 
  • Permanent loss of hearing 
  • Head injury due to failing during a vertigo attack.
Labyrinthitis Diagnostics 
  • Physical examination and patient history - The doctor check your ears and ask you questions about the symptoms that you are experiencing. 
  • Neurological examination may also be performed to rule out other possible causes. 
  • Balance test - posturography 
  • Hearing tests - audiometry  
  • CT scan and MRI 
  • Brain function tests like electroencephalogram or EEG may also be performed. 
  • Caloric stimulation - the nerves of the inner ear are irrigated with warm or cold to access the degree of the ear damage or involvement of the brainstem.
Labyrinthitis Treatment
Treatment of Labyrinthitis involves use of antibiotics if the infection is caused by a bacteria. Labyrinthitis resulting from a viral infection is treated based on the symptoms that you are experiencing.
 
In some cases, Labyrinthitis does not require any treatment and usually heals by its own after a few weeks. Other medications that are used to treat other symptoms may include; 
 
  • Medications to stop vomiting 
  • Antihistamines to treat allergies  
  • Fluid replacement to prevent dehydration 
  • Medications to relieve dizziness episodes 
Labyrinthitis Prevention 
There is no way you can protect yourself from getting Labyrinthitis. However, limiting your movement, resting during the period of attacks, avoiding triggers like bright right and slowly moving from sitting to standing position may prevent your from getting injured or symptoms becoming worse.

What is Hypothyroidism?

Posted by Healthfitline On Monday, April 22, 2013
Hypothyroidism results from hyposecretion of thyroid hormone (T3 and T4) by the thyroid glands. The most common cause of hypothyroidism is Hashimoto, an autoimmune disorder in which the body starts attacking its own thyroid glands.
 
Other possible causes and risk factors of hypothyroidism are;
  • Individuals with previous history of hyperthyroidism whose thyroid glands have been removed (thyroidectomy).
  • Individuals with previous history of hyperthyroidism who have been treated with radioiodine or anti-thyroid drugs.
  • Individuals who previously suffered from neck or head cancer and underwent a radiation therapy.
  • Advancing age which can lead to atrophy of the thyroid gland.
  • Gender - more common in female aged between 30 and 60 years.
  • Medications, such as lithium and iodine compounds.
  • Lack of adequate iodine in the diet.
  • Congenital or present at the time of birth (cretinism).  
Hypothyroidism Symptoms 
Early signs and symptoms of hypothyroidism may include; 
  • Extreme fatigue 
  • Weak and brittle nails 
  • Dry skin 
  • Numbness and tingling of the fingers 
  • Constipation 
  • Menstrual abnormalities - heavier menstrual flow.
  • Hoarseness 
Late Symptoms of Hypothyroidism 
  • Lower than normal body temperature and pulse rate. 
  • Weight gain without increase of food intake. 
  • The skin become thickened 
  • Hair thinning and hair fall 
  • Cold intolerance (individuals always complain of feeling cold). 
  • Slowed speech 
  • Increased irritability 
  • Decreased taste and smell 
Hypothyroidism Complications 
If hypothyroidism is left untreated, it can led to very low thyroid hormones in the blood, a condition known as Myxedema Coma. Myxedema Coma may be precipitated by severe cold, opiods analgesics, sudden withdrawal of thyroid medications and an acute illness or an infection.  
 
Myxedema Coma Signs and Symptoms 
  • Low blood pressure (hypotension) 
  • Low body temperature 
  • Low sodium level in the blood 
  • Low blood glucose 
  • Slowed breathing, leading to high level of carbondioxide in the blood. 
  • Low oxygen levels in the tissue.  
Other complications that can result from hypothyroidism include; 
  • Heart diseases - coronary artery disease, increased cholesterol levels. 
  • Heart attack - in severe cases of hypothyroidism (myxedema coma). 
  • Decreased libido 
  • Birth defects or giving birth to a child with defects. 
  • Dementia- characterized by cognitive and personality changes.
  • Decreased breathing while asleep. 
  • Respiratory muscle weakness and pleural effusion. 
Hypothyroidism Diagnostic Tests 
Physical Examination - The doctor palpitate the thyroid gland for size and other abnormalities. The thyroid gland may be normal, decreased or increased. Doctor also examine the nails, hair, skin and face for any abnormalities. 
 
Serum or Blood Tests -  to measure the blood levels of TSH (thyroid stimulating hormones), T3 and T4. 
 
Other tests that may be performed include; measurement of cholesterol levels, CBC (complete blood count), measurements of electrolytes like sodium and kidney function tests.
  
Hypothyroidism Treatment 
The major goal of hypothyroidism treatment is to replace the missing thyroid hormone in order to restore back a normal metabolism state. A synthetic thyroid medication (levothyroxine) is usually prescribed, based on the level of TSH hormone in the blood.
 
Your doctor will prescribe a specific dose and your TSH levels will be monitored, regularly until when the blood hormones levels will go back to normal. Once the hormone levels have stabilized, you will still continue taking your medications as prescribed by your doctor. However, your doctor will now schedule for a check up every six months or every after one year. Most patients suffering from hypothyroidism will require a lifetime treatment. 
 
Hypothyroidism Prevention 
There is no known ways to prevent hypothyroidism. However, there are several measures that you can take to protect your child and to avoid developing complications; 
 
  • Make sure your newborn is screened for congenital hypothyroidism after birth. 
  • Take your thyroid medications as prescribed by your doctor. 
  • Do not stop taking your thyroid medication even if you are feeling well. 
  • If you are taking any other medications, inform your doctor. 
  • Seek your doctor's help if you are thinking of changing your thyroid medication brand. 
  • Consult your doctor before taking any supplements like iron, multivitamins, calcium etc. 
  • Keep yourself warm if you feel cold.
  • Avoid exposing yourself to cold weather until your thyroid hormone levels have stabilized.
  • Avoid situation that can lead to infection. 
  • Talk to your dietitian about the right diet that will help you to lose weight and prevent constipation. 
  • Seek urgent medical help if you are experiencing signs and symptoms of thyroid medication overdose, such as, feeling your heart beating (palpitation), nervousness, sweating, weight loss, restlessness. If thyroid symptoms are becoming worse or your condition is not improving. If you are experiencing chest pain, difficulty breathing or dizziness.

What is Hyperthyroidism?

Posted by Healthfitline On Wednesday, April 17, 2013
Hyperthyroidism is a thyroid gland disorder resulting from over secretion of thyroid hormones (T3 and T4). Thyroid glands are the butterfly shaped glands that are located on the front lower neck. Their main function is to produce hormones that play an important role in maintaining the overall function of the body, such as energy level, body warmth, muscles and other important functions. 
 
Hyperthyroidism result from any condition that affects the thyroid gland, leading to over production of T4 hormones, such as a thyroid tumor, graves disease (an autoimmune disorder where the body keep on producing more thyroid hormones.
 
The level of thyroid hormone is usually regulated by another hormone known as TSH (thyroid stimulating hormones) that is produced by pituitary glands. When there is an increased amount of T4 hormones in the blood, the pituitary gland try to compensate by decreasing the amount of TSH it produces. 
 
Hyperthyroidism Signs and Symptoms
  • Losing weight despite having a good appetite.
  • Increasing blood pressure
  • Irritability
  • Increased heat intolerance
  • Enlarged thyroid glands (goiter)
  • Thinning of the hair
  • Increased pulse rate
  • Tremors and nervousness
  • Bulging eyes (exophthalmos) - most common in graves disease.
If hyperthyroidism is not controlled, it can leads to a thyroid storm. A thyroid storm can be triggered by several factors such as, a surgical procedure, during intense period of stress, radioactive therapy, heart attack or overdose of thyroid synthetic hormones.
 
Thyroid Storm Signs and Symptoms
  • Increased systolic blood pressure (systolic pressure).
  • Increased pulse rate
  • Nausea and vomiting
  • Diarrhea
  • Muscle weakness
Hyperthyroidism Diagnostic Tests
The following are different tests that can be used to diagnose hyperthyroidism:
 
TSH Serum Test
Serum measurement of TSH, T3 and T4 - expected findings - increased T3 and T4, decreased TSH. Individuals with milder cases of hyperthyroidism may have increased level of T3, normal T4 and decreased TSH. For subclinical cases of hyperthyroidism, they may have normal T3 and T4 but decreased TSH.
 
Antibody tests - Anti-thyroid peroxidase (anti-TPO) antibody and thyroid stimulating immunoglobulin (TSI).
 
Autoantibody Titers Tests
Graves disease - expected findings - significantly increased anti-TPO and TSI.  Toxic multi-nodular enlargement (goiter) and Toxic Adenoma (thyroid benign tumor) - Anti-TPO may be absent or low. Individuals with active hyperthyroidism may also have mild levels of anti-TPO.
 
Scintigraphy - a thyroid test that involves taking an oral solution to produces structural images of the thyroid gland in order to determine the size, function and other thyroid gland abnormalities.
 
Hyperthyroidism Treatment and Management
The management of hyperthyroidism is directed towards reducing the hyperactivity of the thyroid glands in order to relieve various symptoms. Medical management may include;
 
Antithyroid Medications - used for a long time management of hyperthyroidism in children, pregnant women and adults waiting for a radioactive treatment.
 
Medications to control increased pulse rate (tachycardia) and to decrease palpitation, such as propranolol and beta blockers.
 
Radioactive Iodine Treatment - hyperthyroidism treatment of choice for adults and non pregnant women.  Radioactive iodine works by destroying the thyroid gland. However, it is not given to individuals with severe cases of ophthalmopathy. Surgery may performed for severe cases of ophthalmopathy (orbital decompression). Other way to manage ophthalmopathy is through  radiation therapy.
 
Removal of thyroid gland (thyroidectomy) - for severe cases of hyperthyroidism that do not respond to other therapies.
 
Other non pharmaceutical management of hyperthyroidism include;
  • Increasing fluid intake to prevent dehydration.
  • Monitoring of the vital signs.
  • Diet high in calories and protein.
  • Frequent small meals.
  • Providing a cool, quiet environment for the patient.

Psoriasis Disease Overview

Posted by Healthfitline On Tuesday, April 9, 2013
Psoriasis is one of the most common type of skin disorder, affecting almost 2% of the population. The cause of psoriasis is unknown but it is believed to have a hereditary connection. Current studies suggest psoriasis as an autoimmune disorder, where the immune system attacks its own body cells.
 
In normal healthy skin, cells are produced every after 26 to 28 days.  In psoriasis the skin cells are produced at a very fast rate, usually within 3 to 4 days. When this happens, the newly formed cells moves faster to the skin surface as the dead cells build up on the skin surface forming up flaky scales. This rapid proliferation process affects the whole process of skin layer formation. 
 
Psoriasis Risk Factors
The following are some of the risks factors that can worsen the condition or trigger an onset of an attack;
 
  • Emotional stress and anxiety
  • Hormonal changes
  • Very dry skin
  • Skin trauma or injuries
  • Some medications, such as some anti-hypertensive drugs and anti-malaria medications.
  • Exposure to excessive sunlight
  • Excessive consumption of alcohol.
  • People with weakened immunity, such as AIDs patients.
Psoriasis Symptoms
Psoriasis symptoms may disappear for sometimes to re-appear once again later on in life. The main symptom are lesions that appear red, flaky patches covered with scales.  If the scales are scrapped, they expose a dark red skin that tend to bleed. Psoriasis lesions are commonly found on the scalp, elbows, lower back, knees and on the genitals. In about a quarter of the patients suffering from psoriasis, discoloration, crumbling of the nail edges and separation of the nails plate is also present.
 
Other symptoms may include, palms and soles lesions, (palmar pustular psoriasis) genital sores in males and dandruff on the scalp.
 
Psoriasis Complications
Possible complications associated with psoriasis include;
  • Arthritis of multiple joints occurs in about 5% of individuals suffering from psoriasis.
  • Erythrodermic psoriasis - the infection spread to the whole body surface.
Psoriasis Diagnostics Tests
The confirmation of psoriasis diagnosis is usually made by looking at the presenting symptoms, the plaque-type skin lesions. The doctor or the nurse inspects your skin for the lesions. Your family history is also taken to identify possible hereditary connections. Other tests that may be performed include; a biopsy test, where a sample of the affected tissue is taken for further analysis.
 
Psoriasis Treatment and Management
There is no cure of psoriasis and any treatment given is directed towards slowing down the rapid growth of the skin cells and to help in healing the skin lesions. The following are the different types of treatments that are used to manage psoriasis;
 
Topical Agents - Topical medications are used to slow down the rapid growth of the skins cells, without affecting other tissues.  They come in different forms and may include; lotions, pastes, ointment, creams or shampoos. In some cases, topical steroids may also be prescribed to minimize the inflammatory process.
 
Intralesional Medications - These are steroid medications that are directly injected into the skin psoriasis patches that do not react to other treatment. Such as Aristocort, Kenalog-10 and Trymex.
 
Systemic Medications - Only used in treating severe cases of psoriasis that do not respond to other treatment due to their serious withdrawal effects (side effects). 
 
Photochemotherapy - a process where psoralen medications and ultraviolet light are combined in treating psoriasis. In photochemotherapy, you receive photosensitizing medication and at the same time, you get exposed to the ultraviolet light. The therapy is believed to work by slowing down the whole process of rapid reproduction of the skin cells.

Psoriasis Prevention
There is no known way to prevent yourself from acquiring psoriasis. However, there are a few things that you can do to protect your skin or to prevent triggering an onset;
 
  • Daily baths using oils, aveeno oilated oatmeal or a coal tar preparation, together with a soft brush may help in removing the scales.
  • Apply any topical medication as prescribed to help in softening the thickened skin.
  • Avoid scrubbing your skin too hard to avoid irritating it.
  • Avoid situations or stress that can trigger an attack.
  • Maintain a regular skin care routine.
  • Keep your skin clean and well moisturized.
  • Avoid excessive exposure to sunlight.

What is Nephrotic Syndrome?

Posted by Healthfitline On Sunday, April 7, 2013
Nephrotic syndrome is not a specific kidney disease but a disorder that results into various symptoms. It can result from any disorder or disease that affects kidney glomeruli; the small blood vessels found at the end of the kidneys tubules that filter waste products from the blood.
 
When the glomeruli capillary membrane is damaged it allows excessive protein to leave the body, leading to decreased protein (albumin) inside the blood. Albumin plays an important role in maintaining fluid balance inside the body. Nephrotic syndrome is more common in children but it also occurs in adult.
 
Causes of Nephrotic Syndrome
Any disease or condition that destroys or damages the glomerular capillary membrane. Such as;
 
Chronic glomerulonephritis - a long term disease of the kidney that results into inflammation of kidney glomeruli.
 
Other conditions that can lead to Nephrotic Syndrome are; Diabetes Mellitus, Amyloidosis of the kidneys (disease in which abnormal protein known amyloid accumulates in body kidneys), Lupus Erythematous, Multiple Myeloma and certain medications. 
 
Symptoms of Nephrotic Syndrome 
  • Edema - a major symptoms of Nephrotic Syndrome. The edema may occurs around the eyes (peri-orbital edema), sacrum, ankles, hands and on the abdomen (ascites).
  • Irritability
  • Headache and malaise
  • Foamy urine due to excessive protein.
  • Weight gain due to excessive fluid inside the body.
Complications
Possible complications associated with Nephrotic Syndrome include;
  • Obstruction of the renal vein by a clot (thromboembolism) - Excessive loss of protein can lead to loss of important proteins that help in clotting.
  • Pulmonary embolism - a clot may move from the vein and travel through the blood to the lungs.
  • Acute renal failure due to decreased blood flowing into the kidneys.
  • Worsening of atherosclerosis - due to increased release of cholesterol in the blood by the liver.
  • Weight loss and malnutrition due to excessive loss of protein. It may be masked by ascites (body swellings).
  • Increased risk of infection - People with Nephrotic syndrome are more prone to getting infections than healthy people.
Nephrotic Syndrome Diagnostics Tests
  • Urinalysis - Protein (albumin) of more than 3.5g/day is the hallmark of diagnosing Nephrotic Syndrome. Other urine findings include; increased white blood cells, increased epithelial casts and granular.
  • Needle biopsy - a sample tissue of the kidney is removed by use of a small needle for further analysis.
  • Protein electrophoresis and immuno-electrophoresis - tests to categorize the type of protein found on the urine.
  • Blood tests may also be performed to measure the amount of albumin in the blood.
Nephrotic Syndrome Treatment and Management
Treatment of Nephrotic syndrome is directed towards preserving the renal functions and preventing other possible complications. Treatment involves, treating of the underlying conditions, such as hypertension.
 
Medications used in treating Nephrotic Syndrome include;
  • Diuretics - usually given to individuals with severe edema.
  • Angiotensin-converting enzyme (ACE) inhibitors, together with a loop diuretics to reduce blood pressure and amount of protein released in the urine. This kind of treatment is not given for severe cases of edema, since it usually takes between 4 to 6 weeks to be effective.
  • Antineoplastic agents - drugs that are used to inhibit and prevent the development of cancer.
  • Corticosteroids - usually used for kidney inflammation diseases, such as membranous nephropathy or other diseases that are hard to treat or to treat relapses.
  • Other management involves diet modification, such as low sodium diet with liberal potassium for individuals with normal potassium.

Malignant Skin Tumors

Posted by Healthfitline On Tuesday, March 19, 2013
The three most common types of malignant skin tumors are; Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC) and Malignant Melanoma (the third most common). Basal cell carcinoma is the most common type of the three, originating from basal cells. The tumor tends to appear on skin areas that are consistently exposed to sunlight (like face) and they are more common in regions where people are subjected to intense radiation from sunlight.
 
Basal cell carcinoma usually begins as a small waxy nodule. However, as it enlarges in size, it undergoes central ulceration and crusting.
 
Basal Cell Carcinoma Risk Factors
The following are risk factors that increases your chances of acquiring basal cell carcinoma:
 
  • Age - on average, basal cell carcinoma is more common in adults aged 60 years and above.
  • Chronic exposure to sunlight - people living in areas that are subjected to intense amount of sunlight.
  • Light skinned individuals - people with light skin tend to have low melanin (melanin is the natural substance that give a skin its color).  The light skin tends to observe more heat than darker skin, hence increasing your chances of developing basal cell carcinoma.
  • Gender - more common in male than females.
  • Family history of skin cancer
  • Exposure to radiation and other toxic substances.
  • Skin conditions like xeroderma pigmentosum may also increase your chances of acquiring basal cell carcinoma.
Basal Cell Carcinoma Symptoms
Small waxy nodule or bump with pearly borders and visible blood vessels may be present. May also appears as shiny, flat, gray or yellowish looking plaques. In people with darker skin, the nodule may appear black or brownish.
 
Basal cell carcinoma is usually characterized by invasion and erosion of the adjoining tissues but it rarely metastasizes. 
 
Squamous Cell Carcinoma
Squamous cell carcinoma is a more severe form of skin cancer, originating on the epidermis (outer most layers of cells in the skin). It usually occurs on sun-exposed areas but it may also develop from a normal skin or from pre-existing skin scars or lesions, such as actinic keratosis. Unlike basal cell carcinoma, squamous cell carcinoma is highly invasive and easily metastasize through lymphatic system or blood.
 
Squamous Cell Carcinoma Symptoms
Symptoms may include, a rough, thickened, scaly tumor. The tumor tends to be more invasive and may cause bleeding. Secondary infection may occur on the affected part. 
 
Diagnosis of Basal Cell and Squamous Cell Carcinoma
Skin biopsy and histological evaluation - the doctor remove a sample of your infected skin for further examination and analyses in order to confirm whether you are having a skin cancer or not. To measure the size, staging and to determine the most effective approach to treat the tumor.
 
Treatment of Basal Cell and Squamous Cell Carcinoma
The type of treatment given depends on the location of the tumor, the type of cell affected, depth, its invasion ability, previous treatment and patient preference. However, the main goal of any cancer treatment is to remove the tumor entirely.
 
Surgical management of both basal cell and squamous cell carcinoma include;
Mohs' Micrographic Surgery - One of the most accurate and effective type of surgery that involves removal of the cancerous tumor layer by layer. The doctor removes each layer and then examine it under a microscope in order to make sure no cancerous cells are left. Mohs' Micrographic surgery is the most recommended surgery for both basal cell and squamous cell carcinoma.
 
Electrosurgery - Electrical energy is applied on the tissue to destroy the tumor, usually followed by excision of the tumor by use of a curette. 
 
Cryosurgery - A cold liquid nitrogen is applied to the tumor to freeze and destroy it. This method is usually effective if tumor is small and has not invaded deep inside the skin.
 
Surgery - Tumors can be removed through surgery. The doctor make an incision through your skin to remove the cancerous tumor by cutting it and then stitching (suturing) the skin back.  A reconstructive surgery may be needed, depending on the size and where the tumor is located.
 
Topical Application - Topical ointments may be used to treat basal cell carcinoma, since some of them tend to be very superficial and do not penetrate deep inside the skin.
 
Other ways to treat skin cancer is through a radiation therapy - a procedure where beams of intense energy is used to destroy the cancerous cells. One major problem with radiation therapy is that, both healthy and cancerous cells are destroyed, weakening the immune system even further.
 
Prevention of Basal Cell and Squamous Cell Carcinoma
  • Avoid tanning your skin if your skin tends to burn easily.
  • Wear sun protection while exposing yourself to sunlight.
  • Avoid un necessary exposure to sunlight or exposing yourself in mid day sunlight.
  • Apply sunscreen to protect your skin from getting burned by sun rays.
  • Use sunscreen with SPF higher than 15 to protect yourself fully from ultraviolet light.
  • Check your skin regularly to make sure no new lesions are developing or pre-existing lesions are not changing. 
  • Seek medical help if you notice any change in your skin or from a pre-existing lesion.

What is a Collapsed Lung (Pneumothorax)?

Posted by Healthfitline On Friday, March 15, 2013
Lungs are covered by two serous membrane; the parietal pleura and the visceral pleural. Parietal pleura is outermost covering which is attached to the inner thoracic wall. Visceral pleura is the most inner membrane that is directly attached to the lung. The space between the parietal and visceral is what is known as the pleural cavity or pleural space.
 
For lungs to expand and function normally, the air pressure in between the pleural space must remain negative. In pneumothorax, the air enters the pleural space, when this happens, the lung cannot expand as it normally does, leading to lung collapse.
 
Pneumothorax Risk Factors
  • Smoking
  • Frequent invasive chest procedures.
  • Respiratory infections, such as COPD, asthma, TB, whooping cough and pulmonary fibrosis.
  • Gender - More common in men than women.
  • Tall and underweight individuals.
  • Individuals requiring mechanical ventilation to help in breathing.
  • Individual with previous history of pneumothorax.
Types of Pneumothorax
The three different kind of Pneumothorax are: Simple or Spontaneous Pneumothorax, Traumatic and Tension Pneumothorax.
 
Simple or Spontaneous Pneumothorax occurs when air enters the pleural space after a small blisters or a small air filled area (bleb) ruptures or breaks. It may also occurs on healthy individuals in the absence of chest injuries.
 
Traumatic Pneumothorax occurs as result of injuries or chest trauma. Such as, rib fractures, penetrating chest trauma - gun shot, stab wounds and other situations that may lead to chest injuries. The air moves out of the lungs through the injured area to the pleural space, leading to lung collapse. It can also result from chest injuries from invasive procedures, like lung biopsy.
 
Tension Pneumothorax may occurs as result of other pneumothorax or injuries. The air enters the pleural space and get trapped inside. When this happens, there is increased tension inside the pleural space, causing lung to collapse. The heart and trachea may also shifts towards the un affected side of the chest (mediastinal shift).
 
Symptoms of Pneumothorax
Simple or uncomplicated pneumothorax may cause;
  • Sudden pleuritic pain or chest pain
  • Minimal respiratory distress
  • Chest discomfort
  • Increased heart rate
Large pneumothorax or collapsed lung may cause;
  • Acute respiratory distress (low blood pressure, rapid breathing, shortness of breath).
  • Nervousness and anxiety
  • Difficulty of breathing
  • Feeling of air hunger
  • Use of accessory muscles like abdominal muscles when breathing.
  • Bluish discoloration of the mouth membrane and tongue (central cyanosis).
Pneumothorax Complications
Possible complications associated with pneumothorax include;
  • Acute respiratory failure
  • Low blood pressure leading to shock
  • Tension pneumothorax
  • Mediastinal shift - movement of heart, great vessels, trachea and esophagus on one side of the chest.
Pneumothorax Diagnostic Tests
Some of the tests performed to diagnose pneumothorax include;
  • Auscultation (listening) of breath sounds using a stethoscope - may be decreased or absence.
  • Chest x-ray - used to produce images of the lungs and surrounding structures.
  • Arterial blood gas - to measure the level of oxygen and carbon dioxide inside the lungs.
  • Computed tomography (CT) may also be performed for more detailed structural images.
Pneumothorax Treatment
The type of treatment given depends on the severity and what causes the pneumothorax. If only minimal respiratory distress is presence and only a small portion of the lung has collapsed, your physician may recommend frequent x-chest to monitor the lung until when the lung re-expanded and resume normal function. In such cases, you may need to be hospitalized for closer monitoring. You may also be put on supplemental oxygen during that period.
 
Thoracentesis (Needle) and Chest Tube Insertion
If a large portion of lung has collapsed, pneumothorax is usually an emergency case. The goal of treatment is directed towards evacuating the air or the blood from the pleural space. A small need may be used to aspirate the fluid and air in the plural space (thoracentesis).
 
The other way to treat pneumothorax is by insertion of a chest tube. A chest tube is inserted between the ribs to the pleural space. The chest tube is then attached to a suction device that helps in removing the blood and air from the pleural space. The chest tube is then left in place for several hours or days,  until when the lung has fully re-expanded.
 
In some instances, excessive amount of blood may enter the chest tube within a very short time. When this happens, the blood in chest tube may need to be filtered and then transfused back to the system, a process known as autotranfusion.
 
Surgery
Surgery is rarely performed since most lungs are able to re-expand and resume normal function after a chest tube drainage. As a rule of thumb, surgery (thoracotomy) is usually recommended if initially, more than 1500 mL of blood is aspirated by use of the needle (thoracentesis) or by chest tube or if the chest tube drainage continues to be more than 200mL per hour. Thoracotomy is a surgical procedure that involves opening of your chest cavity. In emergency cases, it is usually performed if a heart injury is suspected, secondary to the chest trauma.
 
Pneumothorax Prevention
There is no known specific ways to prevent pneumothorax but you can decrease your chances of developing pneumothorax by cessation of smoking and taking care of your chest to avoid injuries.

Glaucoma Overview

Posted by Healthfitline On Monday, March 11, 2013
Glaucoma is not a single condition but a combination of eye conditions, resulting from an optic nerve damage. The most common cause of glaucoma is an increase in the intraocular pressure (the pressure inside your eye is increased). Glaucoma is the leading cause of non-reversible blindness in the world. 
 
Glaucoma Causes and Pathophysiology
The fluid inside the eye (known as aqueous humor) flows in between the iris and the lens, nourishing the cornea, lens and other parts of the eye. Immediately after, the fluid flows out through a drainage system at open angle of around 45 degree between the iris and the cornea. If the angle between the iris and the cornea become narrowed or it is blocked, the fluid remains inside the eye and drainage is restricted.
 
This leads to an imbalance between the amount of aqueous humor been produced and one flowing outside, resulting in increased pressure inside the eye (IOP). Normal intraocular pressure is between 10 and 21 mmHg.
 
One accepted theory suggest that glaucoma develops from the direct mechanical damage to the retinal layer of the eye by the increasing intraocular pressure. The other theory (known as ischemic theory) suggests that, the increased pressure lead to compression of the small blood vessels of the optic nerve, leading to injury and death of the cells. 
 
Glaucoma Risk Factors
The following are risk factors associated with glaucoma; 
  • Family history of glaucoma
  • Ethnic background 
  • Older age
  • Other medical conditions - diabetes mellitus, heart diseases, migraines syndrome, high blood pressures and hypothyroidism.
  • Other eye conditions - such as myopia (nearsightedness).
  • Eye Injuries
  • Long time use of topical or systematic corticosteroids (steroids). 
Stages of Glaucoma 
Glaucoma usually develops gradually over a long period of time and initially, no symptoms are present. This is the reason why regular examination of the eyes should be done by an Ophthalmogist to be able to detect possible risk factors of glaucoma or to detect glaucoma at an early stage to avoid vision loss.  A comprehensive periodic eye examination is recommended for all adults starting at the age of 40 years and more often for high risk groups.
 
Glaucoma usually undergoes various stages before a vision loss can occur. These four stages of glaucoma are; 
 
The initiating Events - These are the risk factors or precipitating factors that lead to predispose someone to developing glaucoma. Such as illness, congenital abnormalities of the eyes, long term use of medications that dilates the eyes. 
 
The second stage involves the structural alteration of the fluid drainage system. For example, when the iris moves forward to block the angle between the cornea and iris, leading to blockage. 
 
The third stage is the functional alteration - The increased intraocular pressure inside the eye lead to compression of the small blood vessels, impairing the blood flow to optic nerve. This leads to the fourth stage which is the optic nerve damage. 
 
The Optic Nerve Damage - Results from the atrophy and death of the optic nerve, due to decreased blood flow to the eye. 
 
Visual Loss - This the final stage that is characterized by progression visual field defects and vision loss. 
 
Types of Glaucoma 
The four recognized types of glaucoma are: open-angle glaucoma, angle-closure glaucoma (also known as pupillary block), congenital glaucoma and glaucoma that develop from other conditions. The most common type of glaucoma in adults is the open-angle glaucoma and angle closure glaucoma.  
 
Open-Angle Glaucoma 
In open-angle glaucoma both eyes are affected but one eye may be severely affected than the other. The three different types of open-angle glaucoma are: chronic open-angle glaucoma (COAG), normal tension glaucoma and ocular hypertension. In all the three types of open-angle glaucoma, the anterior chamber (the space behind the cornea and in front of iris) appears normal and the angle is open but the drainage channel (trabecular meshwork) is the one that is blocked, restricting the fluid flow. This causes the fluid to remain inside the eye, hence increasing the pressure inside. 
 
Signs and Symptoms of Open-Angle Glaucoma 
Chronic Open -Angle Glaucoma - visual field defects (not able to see the immediate surroundings clearly), optic nerve damage, intraocular pressure higher than 21mm Hg, headache, ocular pain and seeing of stars. Sometimes, no symptoms are present. 
 
Normal Tension Glaucoma - intraocular pressure of less or equal to 21mm Hg, optic nerve damage and visual fields defects.
 
Elevated ocular hypertension - increased intraocular pressure, headache and ocular pain. 
 
Angle-Closure (Pupillary Block) Glaucoma 
Angle-Closure (Pupillary Block) Glaucoma occurs when there is an obstruction of the aqueous humor outflow. The iris moves forward and partially or completely closes the angle formed by the cornea and iris. As a result the aqueous humor (fluid) cannot flow outside, increasing the pressure inside the eye. The three different types of angle-closure glaucoma are: Acute-angle closure glaucoma, sub acute angle-closure glaucoma and chronic angle-closure glaucoma. 
 
Signs and Symptoms of Angle-Closure (Pupillary Block) Glaucoma  
Acute Angle-Closure Glaucoma - Usually develop suddenly and rapidly progresses to visual impairment. Signs and symptoms of acute angle-closure glaucoma include;  
  • Periocular pain (pain around the eye) 
  • Inflammation of the conjunctiva (conjunctival hyperemia or red eye). 
  • Pain that may be followed by nausea and vomiting, decreasing heart rate and sweating. 
  • Decreasing central visual acuity  
  • Very high intraocular pressure 
  • Swelling of cornea 
  • The pupil becomes vertically oval in shape, semi-dilated and fixed in one position. It also does not reacts to light. 
Subacute Angle - Closure Glaucoma - Consistent blurring of vision, seeing of halos or stars around the lights, temporal headache, ocular pain and the pupil may be semi-dilated. 
 
Chronic Angle-Closure Glaucoma - Marked by a significant visual field loss, headache and ocular pain. The intraocular pressure may be increased or normal.
 
Complication of Glaucoma 
Possible complications associated with glaucoma, if left untreated are: 
  • Tunnel vision (not able to see objects clearly that are not close to the center of the visual fields). 
  • Total vision loss 
  • Blind spots in the peripheral visual fields.
Glaucoma Diagnosis Tests 
A comprehensive eye examination, together with your medical history to determine the risk factors.
 
Other diagnosis tests include;  
  • Tonometry - a test that is used to measure the intraocular pressure. 
  • Ophthalmoscopy - Examination of the eye by use of an ophthalmoscope to inspect the optic nerve. 
  • Gonioscopy - to measure the angle of the opening between the cornea and the iris (anterior chamber). 
  • Perimetry - to access the visual fields. 
  • Visual acuity - to test how clearly you can see from a distance. 
Glaucoma Treatment and Management 
Treatment of glaucoma is directed towards preventing the progression of glaucoma to optic nerve damage. Since glaucoma cannot be cured or reversed, a long time therapy is usually prescribed, in considering to your medical history, the stage of glaucoma, your preference and other factors. The main goal of any treatment is to maintain the intraocular pressure within an acceptable level, in order to prevent further damage. 
 
Medications used to treat glaucoma include both topical and systematic to lower the intraocular pressure. Initially, you may receive a lower dose and then it is adjusted to make sure the desired intraocular pressure is maintained. 
 
The following are different kind of medications that are used to decrease the intraocular pressure; 
 
Miotics (Cholinergic Agents) - Used to increase the outflow of the aqueous humor fluid. Examples include; pilocarpine and carbochol. Possible side effects are: pain around the eye, blurry vision and problem seeing in dark.
 
Adrenergics Agonists - Decreases the production of the fluid and increases the outflow. Examples include; dipivefrin and epinephrine. Possible side effects are; redness of the eye, feeling of a burning sensation inside the eye, feeling of the heart beating (palpitation), increased blood pressure, anxiety, headache and tremors. 
 
Carbonic Anhydrase Inhibitors -to decrease the production of the fluid. Examples are acetazolamide, dorvolamide and brinzolamide. Possible side effects include; Oral medications (acetazolamide and methazolamide) can leads to severe allergic reactions, depression, electrolytes loss, stomach upset, weight loss, impotence and increased frequency in urinations. Topical applications can lead to skin allergies. 
 
Alpha Adrenergic Agonists - to decrease the production of the aqueous fluid. Examples: apracloniddine and brimonidine. Possible side effects are: Eye redness, irregular heart rate, fatigue, dry mouth and nasal passage, swollen eyes. 
 
Prostaglandin Analogs - to increase the outflow. Example is the latanoprost. Possible complications: redness of the eye, burning sensation, feeling of the heart beating (palpitation) and increased blood pressure. 
 
Beta-blockers - to reduce the production of the aqueous fluid. Examples are: betaxodol and timol. Possible side effects are: decreasing heart rate, decreasing blood pressure, fatigue and impotence. Beta-blockers are not recommended for patients with history of lung diseases since they can exaggerates the symptoms. 
 
Surgical Management of Glaucoma 
If medications are not effective in treating glaucoma, surgery may be performed. The following are surgical procedures that can be performed;
 
Laser Trabeculoplasty - laser burns are applied inside the surface of the eye to widen the drainage system to increase the outflow of the fluid. Possible complication of this procedure is sudden rise in intraocular pressure usually 2 hours after the surgery that may continue for a longer period. 
 
Laser Iridotomy - Done to patients suffering for angle-closure glaucoma. A small opening is made in the iris to eliminate the blockage on the pupil and ease the fluid flow. Possible complication include: burning of the cornea, retina or lens, sudden increase in intraocular pressure, closure of the iris opening that was created and blurred vision.
 
Filtering Procedures - Used to treat chronic glaucoma. An opening is made inside the eye (in the trabecular meshwork) to drain the fluid by bypassing the usual drainage system. Possible complications include, hemorrhage, very low or high intraocular pressure and cataracts. 
 
Drainage Implants - An artificial tube is inserted inside the eye to help in draining the fluid away from the eye.
 
How to Prevent Glaucoma 
Have a regular eye checkup - This will help in detecting glaucoma and other eye problems early enough before a permanent damage occurs. 
 
Take your medications as prescribed - This is to make sure the intraocular pressure is maintained within the desired level and avoid further damage to the eye. 
 
Protect your eyes from injuries by wearing eye protection gears while working with equipment that can lead to eye injuries. 
 
Ask your doctor about possible side effects of glaucoma medications and what to expect when taking the medications. 
 
Keep all follow-up appointments with your doctor.

Deep Vein Thrombosis (DVT)

Posted by Healthfitline On Tuesday, March 5, 2013
Deep Vein Thrombosis (DVT) is the formation of a blood clot (thrombus) inside the deep vein, usually a complication of immobility. However, it can also result from other medical conditions that affect the blood circulation. It is more common in elderly but it can develop at any age group. Patients who develop deep vein thrombosis are at risk for pulmonary embolism; a fatal complication. Pulmonary embolism occurs when a clot breaks away and travel through the blood stream until it reaches the lung, leading to serious breathing related symptoms.  
 
Deep Vein Thrombosis Causes and Risk Factors
  • Remaining in one position or sitting down for many hours.
  • Stroke and paralysis
  • Injuries to the blood vessels
  • Family history of blood clotting disorders
  • Pregnancy 
  • Heart failure
  • Oral contraceptive and hormone replacement therapies
  • Obesity and overweight
  • Smoking 
Signs and Symptoms of Deep Vein Thrombosis 
Some signs and symptoms of DVT include; 
  • Low grade fever (usually this is the first sign of DVT) 
  • Skin is warm and tender when touched 
  • Edema and swelling of the extremity 
  • Increased leg circumference or girth 
  • Changes of the skin color of the affected leg
Deep Vein Thrombosis Complications 
Pulmonary Embolism 
Pulmonary Embolism is a life threatening complication of deep vein thrombosis that occurs when the lung get blocked by the blood clot. Signs and symptoms of pulmonary embolism include;
 
  • Sudden chest pain 
  • Headache 
  • Shortness of breath 
  • Feeling dizzy or fainting episodes 
  • Increasing pulse rate or rapid pulse 
  • Profuse sweating
  • Apprehensiveness or feeling anxious
  • Abnormal blood gas values - used to measure the level of oxygen and carbondioxide in the blood to determine how well the lung are functioning (results - increased PaCO2 and decreases PaO2).
Post Thrombotic Syndrome (Post-Phlebitic Syndrome) 
Post-Phlebitic Syndrome is a long term complication from deep vein thrombosis. The veins get destroyed by clots that are formed inside the deep veins, leading to impaired blood flow. Some of the common signs and symptoms of Post-Phlebitic Syndrome include; 
  • Pain and tenderness on the affected leg 
  • Edema or swelling
  • Discoloration of the skin due to decreased blood flow to the leg. 
Deep Vein Thrombosis Diagnosis Tests 
In addition to physical examination, other tests that may be done include; 
  • Duplex Ultrasound - a non- invasive procedure used to visualize the affected leg and the blood clot.  
  • MRI and CT Scans - to visualize the exact location where the clot is located and adjacent  structures. 
  • Blood test – to measure the clotting factors
  • Venogram – A contrast dye is injected into the vein to help the physician to visualize the affected vein. 
Deep Vein Thrombosis Treatment
Treatment of deep vein thrombosis is directed towards making sure the patient remains comfortable and to prevent possible complications. Treatment may include; 
 
  • Use of thrombolytic - to dissolve the blood clots found inside the veins. 
  • Anticoagulant - to prevent further clotting of blood. 
  • Compression stockings - thigh length stockings or knee length stockings may be used. These stockings are used to prevent blood pool and formation of more clots. Proper measurement and application of stockings is needed for them to be effective. 
  • Pain medications
Deep Vein Thrombosis Prevention 
Since deep vein thrombosis results from any condition or situation that impair proper circulation of the blood, there are a few things that you can do to prevent or to help in improving the circulation. Such as; 
 
  • Cessation of smoking 
  • Exercise to help in improving the venous return. 
  • Avoid long hour of sitting or standing in one place. If you are travelling in a plane, move around inside the plane or use something to support your legs when sitting down. 
  • Frequently inspect your legs for edema and swelling.
  • Lose weight if you are obese or overweight.
  • Consult your physician if you notice any unusual swelling on your legs. 
  • Wear compression stockings as recommended by your doctor. 
  • Seek appropriate medical advise as soon as possible.

Types of Benign Skin Tumors

Posted by Healthfitline On Sunday, March 3, 2013
Bening skin tumors are non cancerous skin growth or lessons. Some of them are present at the time of birth, while others develop as one grows older or due to excessive exposure to sunlight. Some of them may grow bigger or darkens over time but most of them are harmless and do not require any medical treatment. However, some do change to cancerous tumors over a time and this one reason why frequent monitoring of any skin lesion is required, so that you can be able to notice changes as soon as they develop.

The following are some of the common bening skin tumors or growth;
 
Cysts
Cysts are sac like structure that are filled with fluid or solid materials. They are slow growing and very common. Most of them develop from an infection or due to clogging of the sebaceous gland.  There are two types of cysts; Epidermoid cysts - commonly occur on the face, neck, upper chest and at the back. Pilar cysts (sabaceous cysts) occurs on the head.

Dermatofibroma
Dermatofibroma is a non cancerous growth of the connective tissues that specifically affects the extremities (legs).  A firm, small, red or nodular growth that usually look like the color of the skin or it may be pinkish brown, caused by accumulation of soft tissues under the skin.

Neurofibromatosis (Formerly Known as Von Recklinghausen's Disease)
Neurofibromatosis is a hereditary genetic disorder, characterized by growth of bening tumors (pigmented patches) that vary in sizes. These tumors can develop anywhere in the nervous system, muscle or bone. In some patients, the tumor do turn to cancerous.

Seborrheic Keratoses
Seborrheic Keratoses are non cancerous tumors of different sizes.  They are wartlike lesions that differ in colors, ranging from brownish to black.  Seborrheic Keratoses are more common in the middle-aged individuals and elderly.  They are usually harmless and rarely cause any discomfort.

Actinic Keratoses
Actinic Keratoses are pre-cancerous skin tumors that develop from over exposure to sunlight. They usually appear scaly, rough with underlying redness. Some of them slowly progresses to malignant skin tumors (Squamous cell carcinoma).

Freckles
Freckles are small, brownish patches on the skin that occur mostly on the face and arm. They become more noticeable when one is exposed to sunlight. They are very common on individuals with fair skin.

Warts
Warts are common bening tumors of the skin caused by viruses (human papillomavirus). There are more common in children between the age of 12- 16 years. However, they can appear at any age.

Keloids
Keloids are small, smooth, firm overgrown tissues that forms at the site of injury or scar. They are mostly common in people with dark skin.

Angiomas
Angiomas are bening tumors or growth that results from dilatation of the blood vessels or due to formation of other new blood vessels. They usually affect the skin and the subcutanous tissues. Most of them are present at birth and occurs as flat, red-violet spots (port-wine angiomas) or raised nodular lesions (strawberry angiomas).   Strawberry angiomas usually disappear a few days into life while port-wine angiomas do persists for a long time.

Lipoma
Lipoma are growth formed by fatty deposits that forms under the skin. They are usually round or oval in shape and are more common in women than men. They tend to occur more often on the back of the neck, forearms, chest, back and on the abdomen.

Moles (Pigmented Nevi)
Moles are some of the most common skin tumors that comes in different sizes and shapes. They also differ in colors, ranging from yellowish, dark brown to black. Some moles are hairly nodules, flat, smooth or raised papules.  Most of them are harmless and rarely do they turn to malignant tumors.
 
Bening Tumor Diagnosis
The best way to diagnose a bening skin tumor is by biopsy. A tissue is apirated on the affected skin and then sent to the laboratory for histologic examination. However, biopsy is only done if the doctor suspects the tumor is malignant or it may be tranforming to malignant by looking at its characteristics. 

Some of the characteristics that may signal a bening tumor that is likely to transform to a malignant tumor include;
 
  • Lack of symmetry - when one side of the tumor is different from the other side.
  • Irregular border - if the edges of the tumor are irregular in shape or appear ragged.
  • Different color - if the tumor appears to be of different color.
  • Tumor diameter - if the tumor keep on in increasing in size in diameter.
In addition to the above assessment, patients are also evaluated for other systemic disorders and other medical conditions that may help in getting a diagnosis.
 
Treatment of Bening Skin Tumors
Most bening tumors do not require any treatment. However, some of them may lead to disfigurement  and may create some discomfort to the individuals concerned. The following are surgical procesure that can be used to treat a bening skin tumor;
 
Currettage and electrodesiccation - A process in which the tumor is removed by use of a currette, together with an electrosurgical units to stop bleeding during surgery.
 
Surgical Tumor Excision - The tumor is surgically removed by cutting through the skin and then stitching back the skin after removal.
 
Cyrosurgery - A process is which a very cold liquid nitrogen is sprayed on the tumor to thaw or freeze and destroy the bening tumor.
 
Intralesional Corticosteroids Therapy (For Keloids) - Steroids solution is directly injected on the lesion to improve its appearance or to reduce its size.
 
Other way to cover up the bening tumors like angioma is by use of cosmetic covermark or dermablend to hide the lessions.

What is Aneursym?

Posted by Healthfitline On Tuesday, February 26, 2013
Aneurysm is the dilation or widening of a local artery that forms on a weakened point on the wall of a blood vessel (artery). It is not clearly known what causes an aneurysm but several risk factors have been associated with it.

Causes of Aneursym (Risk Factors)
  • Atherosclerosis (the deposition of plaques of fatty material on the inner walls). Atherosclerosis is the most common cause of aneurysm.
  • Congenital conditions and diseases. Such as Marfan's syndrome, Turner syndrome, Menkes' syndrome, among others.
  • Increased blood pressure and high cholesterol levels in the blood.
  • Trauma - penetrating arterial injuries.
  • Cigarettes smoking
  • Non infectious inflammatory diseases, like kawasaki disease.
  • Infections - infections from bacterial, fungi and spirochete.
  • Pregnancy - non specific but it is often linked with formation and rupturing of splenic aneurysms.
Types of Aneursym
Aneursym can be divided into two types; according to the structural characteristics and the location, where it is formed.

Aneursym According to Structural Characteristics
There are three different forms of aneurysm, according to structural characteristics. Saccular, Fusiform and Dissecting. Saccular and Fusiform are the two most common forms.
 
Saccular Aneursym - only one side of the blood vessel is affected.
Fusiform - the entire circumference of the blood vessel is dilated or affected.
Dissecting -  a hematoma (blood clot) is formed outside the blood vessels, separating the different layers of the blood vessel walls.

Aneursym According to the Location
Cerebral aneurysm - a dilated or balloned like blood vessels that is found on the brain.
Thoracic Aortic Aneurysm - The most common type and site for  a dissecting aneurysm. It is more prevalent in men between the age of 40 and 70 years. 
Abdominal Aortic Aneursym - Abdominal aneurysm is more common among elderly, Caucasians men (four times more common in men that women). The major cause of an abdominal aneurysm is atherosclerosis.

Signs and Symptoms of Aneursym
The signs and symptoms experienced by an individual depends on the location of the aneursym. In cerebral aneurysm (brain) the main symptom is the headache.

Thoracic Aortic Aneurysm Signs and Symptoms
  • Pain while lying in supine position (the most common symptoms).
  • Change in voice (hoarsness), stridor or complete loss of the voice.
  • Difficulty while swallowing.
  • Difficulty in breathing.
  • Bluish discoloration (cyanosis) that is more noticeable on the chest wall.
Thoracic Aneursym Diagnostic Tests
  • Chest x-ray
  • Transesophageal Echocardiography (TEE) - a  transducer tube is passed through the esophagus to the heart to provide clear images of the heart muscles and other existing parts of the heart.
  • CT scan
Abdominal Aneurysm Signs and Symptoms
  • Abdominal mass pulsation.
  • Feeling of heart beating on the abdomen while lying down.
  • Presence of an aortic bruit. A audible sound that is heard over an obstructed artery.
  • Abdominal or lower back pain.
Abdominal Aneursym Diagnostic Tests
  • Pulsation of a mass in the middle and upper abdomen (this is the most indicative diagnostic test).
  • Presence of systolic bruit that is heard over the mass.
  • Duplex Ultrasonography - to determine the size and location of the abdominal aneurysm.
  • CT scan
Symptoms of a Ruptured Abdominal Aneursym
  • Severe, sudden pain that similar to a sharp knife like pain.
  • Lumbar pain that radiates to the flank and on the groin region.
  • Signs and symptoms of a shock; increasing heart rate (cardiac rate), increasing respiratory rate, Decreasing blood pressure and decreasing temperature.
Aneursym Treatment and Management
Not all aneurysm require immediate surgical treatment.  If the aneurysm is still very small, the doctor may recommend a frequent followup, together with occasional ultrasound. Surgeries are mostly performed if the aneurysm has reached a point or it is big enough  to prevent it from rupturing. Some aneurysm do not need any surgical intervention and can remain stable for a long period of time with frequent observation.

Other treatment of aneurysm include;
  • Closely monitoring and treatment of high lood pressure - increased blood pressure is associated with rupturing of an aneurysm.
  • Open surgery - the treatment of choice for abdominal aneurysms that are less than 2 inches (5.5cm). A bypass graft is used to redirect flow of the blood from the obstructed artery.
  • Endovascular grafts (a prosthetic blood vessels is attached across the aneurysm to relieve obstruction). Used to treat infrarenal abdominal aortic aneurysm.
Possible Complications Associated with Aneurysm Surgeries
  • Bleeding
  • Wound infection at the insertion site.
  • Clot formation (hematoma)
  • Distal ischemia or embolization (decreased blood flow to parts that are away from the site of surgery).
  • Perforation of the aorta
  • Bowel ischemia (decreased blood flow to colon and small intestines).
  • Delayed rupture of the aneurysm.

What is Buerger's Disease?

Posted by Healthfitline On Sunday, February 24, 2013
Buerger's disease also known as thromboangiitis obliterans is an autoimmune vasculitis that is characterized by inflammation of  arteries and veins of the lower extremities. In rare cases, the disease can also affects the upper extremities. Buerger's disease is less common in women and it is more common in men aged in betweeen 20 and 35 years.
 
The cause of buerger's disease is not known but it believed to occur from an autoimmune disorder that attacks both the small and medium blood vessels. When this happens, there is an initiation of an inflammation process inside the blood vessels, resulting into blood clot formation and occlusion (blockage) of  blood vessels.

Buerger's Disease Risk Factors
  • Cigarette or tobacco chewing (the most common risk factor).
  • Gender - more common in male gender, aged between 20 - 35 years.
Buerger's Disease Symptoms
  • Intermittent pain (pains that comes and goes). It usually occurs after an exercise (activity) and relieved by rest (in-step claudication).
  • Numbness and feeling of a tingling sensation on the extremities.
  • Extremities become cool and turn pale after exposure to cold.  A condition known as Raynaud's phenomenon.
  • Decreased or absence of pedal pulse due to insufficient blood flow to the extremities but with normal femoral and popliteal pulses (thigh and behind the knee pulses).
  • Cramps on the arch of the foot that is also relieved by taking a rest.
Buerger's Disease Complications
  • Color change that may lead to ulceration.
  • Gangrene formation (localized death and decomposition of tissues of a part of the lower extremities).
  • Gangrene formation that can eventually lead to toe or leg amputation.
Buerger's Disease Diagnosis
Buerger's disease diagnois tests may include;
  • The doctor may measure segmental limb blood pressure to detect the part of the extremities that is occluded (arterial occlusion).
  • Duplex Ultrasonography - to visualize the extent of the disease progression.
  • Contrast Angiography - A dye is injected on the blood vessels to visualize inside the blood vessels and to identify the diseased portion.
  • Other Blood tests - blood tests to help in ruling out other conditions that may be causing the same signs and symptoms.
Buerger's Disease Treatment
There is no known treatment that can cure buerger's disease and any treatment given is directed towards improving the circulation on the lower extremities, to halt the progression of the disease, to increase patient's level of comfort,  to prevent trauma, infection and other possible complications that may arise from the disease. 

Cigarette smoking is one of the most common cause of buerger's disease and patients are advised to immediately stop smoking and tobacco use.  Symptoms of buerger's disease are relieved by cessation of smoking.
 
Other treatment that may be used include;
  • Use of Vasodilators - Vasodilators are rarely used since they only work by dilating healthy blood vessels.  This may worsens the symptoms since they can divert the blood from the occluded blood by directing it to the dilated healthy blood vessels.  
  • Spinal Cord Compression - a process that uses electrical current to help in treating chronic pain.
  • Ganglionectomy - a surgical procedure that is used to remove tumor or a swelling (ganglion) on the extremity to help in improving blood flow.
  • A regional sympathetic block - injection of  drug on the affected limb to relieve pain.
  • Toe or leg amputation, if gangrene is present.
