Medicine Made Simple

Fleet Enemas: Part 2

2009-10-26T13:46:00.000-07:00

Instructions for an enema include the following:

Fleets enemas are best administered by an assistant, friend or family member.

Always drink a couple of glasses of water or juice prior to the enema; this will prevent dehydration.

Lie down on the side with knees pulled towards the chest. Always lubricate the rectal area with KY jelly.

Gently insert the nozzle about 1-2 inches into the rectum and squeeze content of the container.

Remove the nozzle and wait a few minutes for response.

The Fleet Bisacodyl is a ready-to-use enema widely used in most hospitals. The Fleet Bisacodyl Enema is used for relief of constipation or bowel cleansing before rectal examinations. The enema features;

- Protective shield that prevents contamination.
- Pre-lubricated tip for easy insertion.
- One-way safety valve that controls flow and prevents reflux.
- Easy Squeeze bottle.

The Fleet Bisacodyl Enema is a complete, Latex Free enema with a soft, pre-lubricated Comfortip.

To avoid constipation, it is highly recommended that one eat a healthy diet consisting of roughage (whole grains cereals, bran, fruit, and vegetables), 4-6 glasses of water and some type of regular exercise. This helps keep the bowels stimulated and avoids constipation.

Fleet enemas are generally used to relieve constipation and are meant to be used only for the short term. In most cases, fleet enema is approved for use by a health care professional or a nurse who is fairly knowledgeable about your bowel habits and symptoms. One of the chief reasons why fleet enemas are ordered is to relieve constipation. Other scenarios where a fleet enema may be used is prior to a lower bowel exam, such a sigmoidoscopy, a rectal exam or prior to a barium enema. Some individuals who undergo surgery around the rectal area are often given fleet enema. Fleet enemas are widely available without a prescription over the counter and should never be used for prolonged time.

Once the fleet enema has been applied, the results usually occur in 2-5 minutes. If there is any blood, blistering or pain during or after a fleet enema, your health care physician should be informed.

Fleet enemas should not be used if you have an acute abdominal condition like ulcerative colitis, appendicitis, peptic ulcer disease, nausea, vomiting, fever or lower abdominal pain. Prior to using any fleets enema, it is best to get checked out by a health care professional.

Overuse of fleet enemas can lead to dependence and tolerance to the product.
While fleet enemas are generally safe, the rare side effects include rectal bleeding, blistering, burning or itching.

There are many types of fleet enema and include mineral oil, phosphate or normal saline. For children one should only use mineral oil and normal saline enemas. Fleets phosphate enemas can be purchased from any pharmacy and are indicated for adults only.

Pulse Oximeters : Part 2

2009-10-20T12:34:00.000-07:00

Is a pulse oximeter always reliable?

No, there are times when a Pulse Oximetry is not accurate in the following situations:

1.Individuals in shock who are vasoconstricted and have no
pulse generally cannot be monitored by pulse Oximetry. Other
conditions where the pulse may be absent or very faint include
severe dehydration, heart failure, excessive hemorrhage, peripheral
vascular disease, many collagen vascular disorders and other heart
disorders
2.Occasionally bright white lights in hospital rooms can interfere
with accuracy of the oximeter. The numbers may be amplified.
3.The oximeter is sometimes affected by the use of electrocautery
in the operating room. Other medical equipment that can interfere
with the pulse oximeter includes laser beams, ultrasonic devices
and certain types of electronic hardware.
4.Individuals who are shivering or have a persistent tremor often
give unreliable oximeter reading
5.Nail varnish/polish can also cause erroneously low readings.

What are normal pulse oximeter readings?

In general, pulse oxygen saturation in healthy individuals should be above 95% and above. In patients with lung or heart disease, the oxygen saturation may be lower. When the pulse oximeter reads less than 88%, the individual will definitely show difficulty with breathing and may appear out of breaths.

Are pulse oximeters reliable?

Pulse Oximeters available today are very sensitive and reliable. The degree of accuracy has led to their widespread use not only in the hospital setting, but also for use in emergency rooms, out patients medical centers, ambulatory care medicine, outpatient or walk in clinics and even at home.

What is cost of a pulse oximeter?

Advances in Oximetry have now led to the development of devices which can also measure the levels of carbon dioxide at the skin level. The pulse oximeter had been of a tremendous advance in medicine and serves as a vital tool for monitoring the oxygen status of an individual. The cost of pulse Oximetry device is variable depending on the type one wants. The price ranges from $170-$950

Pulse Oximeters : Part 1

2009-10-20T12:32:00.000-07:00

What is Oximetry?

Oximetry is a simple non invasive medical procedure used to measure the concentration of oxygen in the blood. Oximetry is widely used in the hospital care setting to assess patients who have a variety of lung and heart disorders. The measurement of oxygen is done by an oximeter which is a photoelectric device. The majority of Oximeters are small, portable and reusable. Many home devices can be run on batteries.

Where is a pulse oximeter placed on the body?

The oximeter can be placed on the finger tip, ear lobe or toes. Pulse Oximeters are so called because they react only to pulsations of the blood vessels. If there is no pulse, Oximeters will not pick up the pulsations and oxygen concentration cannot be obtained.

Pulse Oximeters are used in all intensive care units, the neonatal unit, coronary care unit, emergency room and during anesthesia. Portable Oximeters are now widely used on the regular medical floors in hospitals across America. The majority of patients who have emphysema, COPD or congestive heart failure are monitored by pulse Oximetry in the hospital.

How does a pulse oximeter work?

The pulse Oximeters work by transmitting a beam of red and infrared light though a pulsating blood vessel. The ratio of red to infra red blood light transmitted provides a measure of the oxygen saturation of the blood. The oximeter identifies the pulse and then deducts the intensity of color perceived when the pulse is absent. The residual intensity of color corresponds to only the oxygenated red blood. This is shown on the electronic screen as a percentage of oxygen saturation in the blood.

Urine strips for making Diagnosis: Part 3

2009-10-16T10:19:00.000-07:00

Urobilinogen test does provide a clue in patient with hemolytic disorders, live failure, poisoning, resolving hematoma or hepatitis. Sometimes low values may occur when there is failure to produce bile or there is an obstruction for passage of bile. A negative result does not mean there is absence of Urobilinogen. High concentrations of ascorbic acid or sulphonamides can also obscure the color and lead to a false negative test.

The nitrite test pad gives an indirect indication of presence of bacteria. When the pad goes pink it signifies a positive reaction. Abnormal nitrite values may indicate presence of a UTI (usually from gram negative bacteria). While the test is accurate in most cases, false negatives may result if there is ascorbic acid present. To confirm present of a urinary tract infection, send a specimen for bacterial culture. Excessive urination or use of diuretic drugs can often create a false negative test due to dilution. The urine test for nitrite is most accurate when antibiotics have been discontinued for at least 3 days prior to the test

Ketones in urine can readily be identified on a urine strip. Ketones are produced in the body when fat is broken down to generate energy. Ketones are generally seen in

- Diabetic ketoacidosis
- Insulin over dose
- Starvation
- Persistent nausea and vomiting
- Strict dieting
- Stress
- Infections.

When Ketones are detected in urine, the next step is to measure urine glucose. If glucose levels are low, one should immediately seek medical attention.

The urine strip is the most inexpensive method to detect white cells in the urine. While a few cells are always present in urine, more than 20 WBC/ul is considered pathological. WBC in the urine may occur from

- Urinary tract infection
- Kidney abscess
- Bladder infection
- Infected kidney stone

The intensity of the color formed is generally proportional to the number of WBC. Results of the test can be obscured by presence of oxalic acid or oxidizing agents. Other factors that affect the test include high sugar, high protein and presence of certain antibiotics like tetracyclines and cephalosporins.

The urine strip allows at least ten quick clinical measurements in an inexpensive way. The results can then be used to treat or counsel patients for further treatment. To view our urine test kit and prices, please visit www.medexsupply.com

Urine strips for making Diagnosis: Part 2

2009-10-16T10:16:00.000-07:00

Urine glucose is the most frequent diagnosis sought out on a urine strip. Urine strips readily identify glucose in the urine; however, for the result to be reliable one has to ensure that the strip has not expired. If the enzymatic action of enzymes is altered on the pad, then the results may be spurious.

Urine strips are quite sensitive to glucose in the urine and this is one of the fastest and inexpensive ways to check for glucose. Abnormal glucose may be seen in diabetes, pregnancy or after a heavy diet. The sensitivity of urine strip to glucose is decreased when the urine has high specific gravity or ascorbic acid concentration is high

Bilirubin levels on a urine strip are often unreliable. The best way to use urinary bilirubin level is to correlate them with clinical findings and laboratories values.

The occult blood test on a urine strip may detect red blood cells, free hemoglobin or myoglobin. The test is very sensitive and quite useful. Blood may be seen in the urine due to a kidney stone, urinary tract infection, break down of muscle, or red blood cells. When urine has high specific gravity it reduces sensitivity of the strip, while ascorbic acid may cause a falsely negative test.

The protein test pad only gives a rough estimate of protein in the urine. However, false positives may occur if the urine pH is very alkaline. Protein may occur in urine from a variety of conditions including:

- Position
- Strenuous exercise
- Extremes of temperature (too hot or too cold)
- Pregnancy
- Low blood pressure
- Liver cirrhoses
- Renal failure
- Upper respiratory tract infection
- Immune complex disorders
- Sepsis

The urine strip reagent is highly sensitive to albumin and less to globulin

Urine strips for making Diagnosis: Part 1

2009-10-16T10:13:00.000-07:00

Urine strips are widely used in medicine to make a quick diagnosis of numerous medical disorders. The majority of these diagnostic reagent strips are designed only for human use and provide immediate useful information about health. Urine strips are frequently used by physicians and health care professionals in emergency room, outpatient clinics, nursing homes, doctor’s office and mobile ambulatory centers. The majority of urine strips are multipurpose and readily show color changes when an abnormality is identified. Most strips have gradations of color which allows one to judge the severity of the problem. For those who are not familiar with urine strips, the following information is readily available from urine strips:

Specific Gravity: Urine specific gravity is readily obtained from a strip but it only provides a clue to change in urine density. For more accurate testing, one needs to use a calibrated refractometer.

Urine pH is the most widely used property on a urine strip. The test strips are designed to measure pH change values to within 0.5 units. For the most part, urine pH values are okay for emergency use. Abnormal pH levels may be seen in the following conditions:

Alkaline urine

- Urinary tract infection
- Consuming a vegetarian diet
- Systemic alkalosis
- Bowel obstruction- pyloric stenosis
- Excessive vomiting
- Use of alkaline drugs

Acid urine

- Gout
- Fever
- Use of drugs like phenacetin
- Uric acid stones

The test strips are most accurate for pH in the range from 5-9. However, one has to remember that false negatives can occur because the solution may run over from the highly acidic protein test pad to the urine pH pad. Thus, it is important to hold the strip horizontally when evaluating urine for pH. Whenever there is doubt about urine pH, a pH meter can be used to verify your results.

Shoe Covers: Part 2

2009-10-02T11:27:00.000-07:00

Almost all shoes covers available today for health professionals are made from poly lactic acid which is an environmentally friendly fabric that is easy to dispose. It biodegrades into water and carbon dioxide. All shoe covers for hospital use are made in accordance with guidelines from OSHA.

The shoe cover fabric is generally 0.1-0.5 mm in thickness and comes in white or blue colors. Shoe covers are ideal for people who not only work in the health care industry but also for those who process food, do house work, work in hair salons, cook foods or work into pharmaceutical manufacturing industry. Shoe covers available today are very light weight, convenient and easy to use. Most have an elastic band along the edges which helps the cover from falling off.

For individual who have latex allergy, there are even shoe covers which are latex free. Disposable shoe covers are considered to be an investment for hospitals because they limit the spread of diseases. One wears them to protect the environment.
Like disposable gloves shoe covers also are available in mass quantities. The majority of shoe covers available are fire resistant, splash proof and non slippery. Most are non allergenic and are easy to dispose.

Shoe Covers: Part 1

2009-10-02T11:25:00.000-07:00

Every hospital has difficulty controlling and preventing infections. There is a lot of evidence that a number of infections acquired in hospitals are passed on to patients from other people (both health care professionals and non health professionals). Despite all advances in science, infections still remain a major cause of death. With recent epidemic of swine flu and bird flu, the importance of hand washing has again been re-emphasized. Another aspect of prevention or transmission of infection is wearing of shoe covers. Shoe covers are vital for health care professionals who work in the operating rooms or in areas of the hospital where complete anti sepsis is required.

All of us wear shoes and walk into environments which are dirty and unsanitary. Show covers help materials from shoes from falling inside clean environments.
Besides preventing transmission of dirt and junk from the outside, show covers also prevent contamination of personal clothing like socks and shoes. There are many types of shoe covers but most health care facilities prefer the disposal shoe covers which come in one size fits all.

Shoe covers are made from light paper cloth, which has a stretchable fabric so that the fit is perfect around any type of shoe. Once the shoe cover is worn it stays firm and does not easily slip off irrespective of the circumstances. Most shoe cover fabrics are sturdy and prevent transmission of fluid into the shoe or socks.

Surgical Masks

2009-09-10T08:14:00.000-07:00

Surgical masks have always played an important role in preventive medicine. With the advent of Swine and Bird flu, surgical masks have gained even more significance in the world of medicine. Surgical masks were once only worn in hospitals by health care professional and patients. Surgical masks help protect health care workers from bodily fluids, blood, various lung secretions and reduce spread of microorganisms from patients to health care worker and vice versa.

Since the advent of influenza virus, two other airborne viruses have been discovered that have the potential to cause many deaths. Large-scale pandemics of bird and swine flu viral infections have led to use of surgical masks outside health care facilities. The availability of relatively cheap surgical masks has led to high usage among populations in South East Asia. In many Oriental countries, use of surgical masks is a frequent public site to help avoid spread of the common cold virus.

Since the Bird flu scare several years ago, surgical masks have become popular among the public in many parts of America, including Canada and Mexico. There is abundant clinical evidence indicating that surgical masks play an important role in protecting health care workers from contaminated body fluids and aerosol particles. Surgical masks are primarily worn in hospital to prevent inhalation of aerosolized particles including microorganisms.

Awareness of serious viral and bacterial infections has led to development of guidelines regarding use of surgical masks in many health care facilities. Today, surgical masks are advocated for health care professional by the following institutions:

- American National Standards Institute Practice for
Occupational and Educational Eye and Face Protection
- Association of Perioperative Registered Nurses
- Joint Council on Accreditation of Healthcare Organizations
- National Committee for Quality Assurance
- National Institute for Occupational Safety and Health
- Occupational Safety and Health Administration
- The Food and Drug Administration

Eye Protection in health care facilities: Part 2

2009-09-10T04:02:00.000-07:00

What types of safety eye wear is available for hospital workers?

The presently available safety eyewear include:

- non prescription eye glasses
- prescription safety glasses
- goggles
- Face shields that are combined with a surgical mask

Eye goggles are easy to use and do provide an important protective function. Before buying a pair of eye goggles one should look for the following features:

- are the goggles lightweight
- are the goggles easy to wear and comfortable
- Do the goggles protect against fluid splatter
- Do the goggles easily fog up?
- Are the lenses strong?
- Are the goggles resistant to chemicals and fluids?
- Are the goggles scratchproof?

It is highly recommended that one wear eye protection if there is any potential for eye injury. Today, OSHA standards require that all health care facilities make available to their staff appropriate eye protection. To be useful, the eyewear must be of the correct type for the risk encountered and correctly fitted.

Eye protection devices must be maintained if one wants them to last. The lenses should be regularly cleaned – dented, scratched or and soiled lenses can diminish vision and may be a factor in causing injury

Eye Protection in health care facilities: Part 1

2009-09-10T03:52:00.000-07:00

Protection of the eye is very important in health care facilities. Each year thousands of health care workers are exposed to sick patients, contaminated aerosolized environments, infected body fluids, and blood. Surgeons especially are always at risk from flying fragments and body fluids during surgery. Despite protection from prescription glasses, a number of health care workers develop various types of eye injuries. Moreover, besides direct injury to the eye, there is always a potential for coming into contact with infectious organisms or blood.

When the eye is injured or infected, one has to miss work. This adds to loss of manpower and adds more stress on the already overworked workman’s compensation program. There is no dollar figure that can entirely replicate the personal toll these injuries take on injured health professionals.

Eye experts indicate that proper eye protection can significantly reduce incidence of eye injuries in hospitals and related facilities.

What are common causes of eye injuries in a hospital setting?

- Flying objects especially during surgery (blood particles,
bone chips, metal particles)
- Chemicals
- Aerosolized particles
- Fumes
- Laser beams

How can one prevent eye injury at work?

Eye injuries can be very serious and thus a preventive approach is ideal. All individuals who work in a hospital environment should know the following:
- location of nearest emergency eye wash basin
- be aware of all potential causes of eye injuries in
the working environment
- wear proper eye protection
- be familiar with use of eye goggles

If there is any chance that the eye may be injured at work, one should wear eye goggles. There are many types of protective eyewear available today and most work well. The choice of eye goggles is strictly personal.

Sitz Baths: part 3

2009-09-10T02:17:00.000-07:00

The latest styles of Sitz baths also some with prefilled bags of salt water and a plastic tube. The bag is similar to what doctors’ use for intravenous fluids in hospitals. The bag is placed on a pole and then the tube is placed in the bath where it continues to supply water. Most Sitz baths also have small vent to prevent overfilling. The excess water runs down into the toilet basin. Sitz baths that come with prefilled solutions are generally more expensive than regular Sitz baths. For those individuals on a limited budget, one can make some warm water and stir in 1-2 teaspoons of salt or baking soda.

Many alternative care health practitioners recommend use of other supplements to the water- these are not required for wound care and are an unnecessary expense.

Once you have completed the Sitz bath, gently pad the skin dry. One should not rub harshly with a towel.

It is possible to take a Sitz bath while sitting in the bathtub. However, with the buttocks resting on the bathtub floor, Sitz baths may not be effective if there is a problem in the rectal or anal area. After taking a Sitz bath in a bathtub, one needs to stand up and thoroughly wash legs and feet to remove all the junk released from the groin and anal area.

After a Sitz bath, many individuals complain about feeling dizzy or lightheaded. So get up slowly or get someone to help you out of the chair.

To ensure that your Sitz bath lasts, wash it after each use and allow it to dry. The cost of Sitz baths starts around $8.

For more on Sitz bath and supplies, please visit www.medexsupply.com

Sitz Baths: Part 2

2009-09-10T02:15:00.000-07:00

The Sitz bath should be filled with warm water and then one lows the rectal, anal or groin area into the tub. For maximum benefit, one should sit in the bath for at least 15-20 minutes three to four times a day.

Sitz baths are readily available from many pharmacies and medical supplies companies. Most hospital do provide information on where to get Sitz bath and how to use it. In general, Sitz baths are a lot cheaper when bought directly from a medical supply company.

There are several types and styles of Sitz baths and the most important factor prior to using one is to ensure that the Sitz baths fits well in to the toilet.

Some baths are made to fit over a toilet and have a drain so any additional water will not leak when the individual sits down. Other Sitz tubs fit on top of a chair, and there are even combinations of a chair with a Sitz bath.

One can use any large tub as a Sitz bath but most home products are not as sturdy or as durable as the commercial products.

Sitz Baths: Part 1

2009-09-10T01:25:00.000-07:00

A Sitz bath refers to a bath where the lower half of the groin, rectal or anal area is immersed in a small plastic tub that contains warm water. Over the years, many different types of Sitz baths have been developed for individuals with all types of handicaps.

There are several medical disorders that require cleaning the perianal and rectal area with Sitz baths. The medical disorders for which Sitz baths are most frequently recommended include:

- Anal pain
- Anal fissure
- Bartholin cysts
- Cystitis
- Following an episiotomy
- Hemorrhoids
- Proctitis
- Prostatitis
- Rectovaginal fistula

In essence, a Sitz bath is a small tub that fits over the toilet and can be filled with water. The aim of a Sitz bath is to provide pain relief, clean the rectal, perianal and vaginal area, and provide relief from any discomfort.

Most people find significant relief from pain after using Sitz baths. The pain relief is almost instant and does last several hours. It is recommended that one use a Sitz bath at least 2-3 times a day for 5-15 days, depending on the medical disorder.

HPV vaccine: Part 3

2009-06-11T08:32:00.000-07:00

Finally the cost of HPV vaccine

Medicine is foremost a business and nothing is free. A single dose of Gardasil costs $120-$140. Each individual requires three doses over a 6-month period. Further, many physicians are also charging for a consultation fee, cost of syringe and office time. Thus, the average cost for the entire series of HPV vaccine amounts to about $500-$600 plus.

Not all health insurance plans cover Gardasil. Moreover, some insurance plans only cover the vaccine for females in-between the ages of 9-26, the age where the vaccine has been FDA approved. At present, there is no legislation mandating that insurance plans cover the cost of the vaccine.

The pharmaceutical giant, Merck now has released data that the vaccine is also useful in women up to the age of 45. If there is FDA approval for the vaccine for this older group of individuals, perhaps some insurance companies may cover the cost.

At the moment, Gardasil is covered under a federal program for those who have no insurance and to Medicaid eligible children under the age of 18. For those individuals who lack medical insurance, one can check with the physician or the local health clinic to determine if there is program to get the vaccine free.

HPV vaccine: Part 2

2009-06-11T08:31:00.000-07:00

The one reason why Gardasil is not recommended for women over the age of 25 is that by this time it appears many women have already been exposed to HPV. However, there are studies that have documented safety of this vaccine in the older age group. At present, Gardasil is believed to be effective for at least 5 years after injection. Current research is trying to determine if a booster shot at the end of 5 years will extent protection from the vaccine.

All consumers should understand that getting the HPV vaccine does not eliminate the need for future doctor visits. Pap smears are highly recommended in all females when they become sexually active.

As far as side effects are concerned, both vaccines have proven to be quite safe. From the recent clinical trials, the most common side effects observed were redness and pain at the injection site. These transient side effects last for a few days.

Neither Gardasil nor Cervarix is recommended for pregnant women. Once injected with the HPV vaccine, more than 95-98 percent of women are protected from developing cervical cancer

What is all the fuss about the human papillomavirus (HPV) vaccine?

2009-06-11T08:18:00.000-07:00

Cervical cancer is quite common all over the world. The tragedy of cervical cancer is that it affects young females. Current estimates indicate that in America, approximately 11,000 women develop cervical cancer and there are about 3,000 deaths each year. Over the years, a strong link between the human papilloma virus (HPV) and cervical cancer has been established. Furthermore, HPV has also been linked to cancers of the mouth, vulva, anus, and penis. With more people engaging in sexual activities at an earlier age, a vaccine would be a great way to prevent these cancers associated with HPV.

At present two vaccines have been developed to prevent infection from HPV. Both vaccines are administered by an injection in three divided doses. The current injection guidelines recommend that the first injection be followed by the 2nd and 3rd dose, two and six months, apart.

So far, only one vaccine is currently available in North America. Gardasil is currently available and recommended for all girls and young women between the ages of 9 and 26. In different countries, the age of vaccination is slightly variable. For example in Australia, cervarix is recommended for all females between the ages of 10-45 and for boys in-between the ages of 9-15. Cervarix is currently in the clinical trials stage in North America but data indicate that it is just as effective and safe as Gardasil.

The most important factor with both vaccines is that one gets vaccinated prior to becoming sexually active. Current data indicate that if the vaccine is injected in sexually active individuals, it does not get rid of HPV infection and thus protection against cervical cancer is not a guarantee.

Blood in urine: Part 4

2009-06-08T07:32:00.000-07:00

Treatment

When hematuria occurs, the doctor has to treat the underling cause.

Urinary tract infections are treated with antibiotics and within a few days both the symptoms and hematuria will disappear. In rare cases, one may need long-term treatment with antibiotics

Kidney stones generally pass spontaneously through the ureter when one drinks a lot of water and remains active. If this method fails, then there are several other options to reveal kidney stones. One is non-invasive use of ultrasonic shock waves to break up the stone. Other more invasive methods include Cystoscopy or surgery.

Enlarged prostate does require treatment when the patient has symptoms. There is no ideal treatment for enlarged prostate. Every treatment has some negatives. In general, one is treated with medications and these do work well, but they also have side effects. When medications fail, the other options are use of heat, laser, or ultrasonic waves to shrink the prostate.

Immunological kidney disease does require treatment. The treatment depends on the type of kidney disease.

Cancers of kidney and bladder are generally treated with surgery. These tumors generally do not respond well to radiation or chemotherapy. In most cases, surgery is combined with an assorted variety of chemotherapeutic drugs.

Inherited disorders of the kidney which cause hematuria, do not always require treatment. Some disorders may cause extensive kidney damage and dialysis may be the only alternative.

Prevention of blood in urine

Unfortunately, one cannot not prevent hematuria. Even then, one should lead a healthy life style. Drinking adequate water and urinating right after intercourse does help prevent some urinary tract infections

To decrease the risk of kidney stones drink lots of water, limit salt, excess protein, and foods such as spinach.

To decrease risk of cancer, stop smoking, avoid exposure to heavy metals or chemicals and get regular exams from a physician.

Blood in urine: Part 3

2009-06-08T07:04:00.000-07:00

What are risk factors?

Anyone can develop blood in the urine.

Age: Many men in the 5th decade of life develop and enlarged prostate and have blood in urine

Females generally tend to have hematuria in urine from a UTI

Family history may predispose one to kidney stones which may lead to blood in urine.

Medications like aspirin and penicillin can cause blood in the urine.

Athletes who are long distance runners or joggers often develop hematuria.

Diagnosis

After a complete history and physical examination, hematuria work up depends on the suspected cause.

Urine analysis can determine if there is blood, infection, or a stone. Urine analyses is not specific for diagnosis and some type of radiological study is usually required.

Imaging with CT scan, MRI, or ultrasound can help look at the urinary tract.
Sometimes a long flexible camera (cystoscope) is passed from the penis or vagina into the urethra and up the ureter. The camera can help visualize structures and biopsy can be obtained.

In a few cases the diagnosis of hematuria may not be evident. This may occur if one has had a prior exposure to a drug or an environmental toxin.

In elderly individuals, the cause of hematuria is almost always investigated to rule out a cancer.

Blood in urine: Part 2

2009-06-08T06:54:00.000-07:00

Causes of hematuria

There are a number of structures that make up the urinary tract. Starting with kidney, there are the ureters, bladder and urethra. The kidneys remove waste products and make urine. The urine is then carried by the ureter to the bladder where it is stored. When the bladder is full, the urethra opens and one urinates. blood can originate from any one of these structures.

Urinary tract infections (UTI) are common in women then men. Often some women develop microscopic hematuria during a UTI. This usually clears up once the UTI is treated with an antibiotic. No investigations are needed.

Infections of the kidney is known as pyleonephritis and can also result as microscopic hematuria. The condition is associated with significant flank pain, fever, and difficulty passing urine. The condition is typically treated with antibiotics.

Stones are a common cause of blood in urine. Urinary stones are excruciatingly painful and often cause both gross and microscopic hematuria. Identification of stones is easy with a dye study. When the stone has passed, hematuria usually clears up.

Enlarged prostate is a leading cause of hematuria in man over the age of 50. The prostate is located at the base of the bladder. As men age, the prostate gets bigger and compresses the urethra; often this leads to difficulty in urination. Often the condition is associated with both gross and microscopic hematuria. The condition is easily diagnosed with a rectal exam or an ultrasound.

Kidney disorders; There are many kidney disorders that can cause microscopic hematuria. Most of these disorders are either infections or immune mediated. These disorders also have other organ involvement and need to be worked up. Most of these immunological kidney disorders present much early in life.

Cancer: Gross hematuria is often the first sign of cancer of bladder, kidney or prostate. Unfortunately, when gross hematuria occurs the cancer is generally more advanced.

Trauma is a common cause of hematuria. Individuals into contact sports may see blood in urine after trauma.

Medications like aspirin and blood thinners can also cause blood in urine.

Strenuous exercise can cause gross hematuria. This is most probably related to dehydration, trauma to the bladder or breakdown of red cells. The condition usually improves within a few days.

Why do I have blood in my urine?

2009-06-08T06:49:00.000-07:00

Having blood in urine is not normal. Seeing blood in urine can be a frightening experience for most people. When blood occurs in the urine, the condition is medically known as hematuria. In most cases, having blood in urine is not a cause for alarm. Sometimes participating in strenuous sports can cause blood to appear in urine. Some footballers often see traces of blood in urine after being knocked down on the sports field. Other common causes of blood in urine include kidney stones and drugs. However, in the elderly individual blood in urine may signal the appearance of a cancer.

Blood in the urine is classified as gross or microscopic. When the urine is only slightly red and red blood cells are only seen under a microscope, this is known as microscopic hematuria. When there is frank blood in urine, this is known as gross hematuria.

When gross hematuria occurs, one must always rule out a cancer. When there is microscopic hematuria, the cause may be an infection or a stone.

Hematuria that is caused with exercise or sports trauma usually disappears within a few days and does not require any extensive work up

Symptoms

In many individuals, microscopic hematuria may present as red or pink colored urine. It takes only a few red blood cells to make the urine look red. In most cases, there is no pain associated with blood in urine.

Is there a risk from taking these medications?

Yes, all blood thinning medication can cause bleeding. Thus one should avoid activities that can lead to trauma to the body, otherwise severe bleeding can occur.

Can blood clots be dissolved instantly?

Yes, there are medications (thrombolytics) which can rapidly dissolve blood clots. However, there are specific indications for use of these medications and they all carry a higher risk of complications. Their use is only limited to hospital patients.

Is surgery ever used to treat blood clots from the legs?

Yes, in very rare cases surgery (thrombectomy/embolectomy) is sometimes used in the treatment of blood clots. However, this is done for life or limb threatening cases only. There is no role for surgery in the routine treatment of blood clots in the legs. The surgery is hazardous and fraught with complications. However, it is life saving.

What happens if I am unable to tolerate a blood thinning medication?

Today, there are several devices (filters) which can be placed in the vein to prevent blood clots from migrating to lungs. The filter has to be placed before the blood clot has broken off. The filter acts like an umbrella and is quite effective in preventing the blood clot from moving to lung. These devices have an umbrella like appearance and do not dissolve the clot but prevent it from going to lungs. Filters are more commonly used in individuals who can not take blood thinners. There are both permanent and temporary filters available today but they do cost a fortune. Some of the temporary filters cost more than $15, 000.

What is treatment of a blood clot?

If a blood clot is found in the deep veins, you will require admission to hospital for at least 4-7 days. Following some blood work, you will be started on heparin.

What is heparin?

Heparin is a blood thinner that is given intravenously. It does not dissolve the clot but helps to stabilize the clot so that it does not move. After a few days, you will be started on an oral medication called warfarin and then discharged home. Anyone who receives warfarin needs his or her blood assessed on a weekly to monthly basis to ensure that blood thinning is adequate.

How long do I need to take a blood thinner?

For a first time blood clot, you will need to take warfarin for at least 6-9 months. Those with recurrent blood clots will require warfarin for an indefinite time.

Are there any other medications one can take for blood clots?

Yes, the newer medications are called low molecular weight heparins (LMWH). These medications do not require monitoring and can be taken at home. Unfortunately they need to be injected daily and are more expensive.
