5'-Nucleotidase: How the test is performed, Prepare for the Test, Normal Values, Alternative Names

0 comments

5'-Nucleotidase

5'-nucleotidase (5'-NT) is a protein produced by the liver. You can do a test to measure the amount of this protein in the blood.

How the test is performed

Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with a disinfectant (antiseptic). The doctor puts a rubber band around the upper arm to apply pressure to the area and make the vein swell with blood.

The doctor then gently inserts a needle into the vein and blood collected in a vial or tube attached to the needle. The elastic band is removed to restore circulation.

Once it has collected the blood sample, the needle is removed and covered the puncture site to stop any bleeding.

In infants or young children, you can use a tool called a lancet to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, a slide or test strip. Finally, you can place a bandage over the area if there is any bleeding.

Prepare for the Test

If necessary, the doctor will instruct you to withhold drugs that may interfere with test results, including:
Acetaminophen (Tylenol)
Halothane
Isoniazid
Methyldopa
Nitrofurantoin
What you feel during the examination

When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Subsequently, there may be some throbbing.
Why the test is performed

Your doctor may order this test if you have signs of a liver problem. It is used primarily to determine whether the high level of protein is due to liver damage or injury of skeletal muscle.

Normal Values

The normal value is 2 to 17 units per liter.

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Significance of abnormal results

The higher than normal levels may indicate:
Cholestasis
Destruction of liver cells
Hepatitis
Hepatic ischemia
Liver tumor
Use of a medication that damages the liver
Risks

Veins and arteries vary in size from one patient to another and from one side of the body to another, why get a blood sample from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include:
Excessive bleeding
Fainting or dizziness
Hematoma (blood accumulating under the skin)

Infection (a slight risk any time there is skin breakdown)

Vulvovaginitis: Symptoms, Treatment, Causes, incidence and risk factors, Exams and Tests, prognosis, health care, Prevention and Alternative Names

1 comments
Vulvovaginitis

It is an inflammation or infection of the vulva and vagina.

Causes, incidence and risk factors

Vulvovaginitis can affect women of any age and is very common. It can be caused by bacteria, yeasts, viruses and other parasites can also be caused by sexually transmitted diseases, and various chemicals found in bubble baths, soaps and perfumes. Environmental factors such as poor hygiene and allergens may also cause this condition.

Candida albicans, which causes yeast infections, is one of the most common causes of vulvovaginitis in women of all ages. The use of antibiotics can lead to yeast infections by destroying the normal antifungal bacteria that live in the vagina. Yeast infections typically cause genital itching, a thick, white vaginal discharge and other symptoms. For more information see: vaginal yeast infection.

Another cause of vulvovaginitis is bacterial vaginosis, an overgrowth of certain types of bacteria in the vagina. This condition can cause a vaginal discharge thin, gray and a fishy odor.

Another common cause is a sexually transmitted disease infection known as vaginitis, which causes genital itching, vaginal odor, and heavy vaginal bleeding that may be yellow-green or green.

Bubble baths, soaps, vaginal contraceptives, feminine sprays, and perfumes can cause irritating itchy rashes in the genital area, while tight fitting or nonabsorbent clothing sometimes cause heat rashes.

Irritated tissue is more susceptible to infection than normal tissue and many infection-causing organisms thrive in environments that are warm, moist and dark. All these factors not only contribute to the cause of vulvovaginitis, they frequently prolong the recovery period.

Lack of postmenopausal estrogen can cause vaginal dryness and thinning of the skin of the vulva and vagina, which also lead to or worsen genital itching and burning.

Nonspecific vulvovaginitis (where you can not identify any cause) can be seen in all age groups but occurs most commonly in young girls before puberty. Once puberty begins, the vagina becomes more acidic, which helps prevent infection.

Nonspecific vulvovaginitis can occur in girls with poor genital hygiene and is characterized by a foul-smelling, brownish-green and irritation of the opening of the mouth and vagina. This condition is often associated with the proliferation of a type of bacteria is typically found in feces, which are sometimes spread from the rectum to the vaginal area by wiping from back to front after using the bathroom.

You should consider the possibility that there existed sexual abuse in children with unusual infections and recurrent episodes of unexplained vulvovaginitis. Neisseria gonorrhoeae, the organism that causes gonorrhea, produces gonococcal vulvovaginitis in young girls. Gonorrhea related vaginitis is considered a sexually transmitted disease. If laboratory tests confirm this diagnosis, young girls should be evaluated for sexual abuse.

Symptoms

* Irritation and itching in the genital area
* Inflammation (irritation, redness and swelling) of the labia majora, labia minora, or perineal area
* Vaginal discharge
* Foul vaginal odor
* Discomfort or burning when urinating

Exams and Tests

Vaginal symptoms are best diagnosed by a doctor. If you have been diagnosed with a yeast infection in the past, try over-the-counter products. However, if symptoms do not disappear completely in about a week, be sure to contact your doctor, as many other infections have similar symptoms.

The doctor will perform a pelvic exam, which can show vulvar or vaginal skin red and sensitive. You must inspect any injury or ulceration.

Typically, you perform a wet prep (microscopic evaluation of vaginal discharge) to identify a vaginal infection or overgrowth of yeast or bacteria. In some cases, a culture of vaginal discharge may identify the organism causing the infection.

Treatment

You can also use a cream containing cortisone to relieve some irritation. If an allergic reaction may also be prescribed an antihistamine. For women who have irritation and inflammation caused by low estrogen levels (postmenopausal) may prescribe a topical estrogen cream.

To help with the healing process and prevent future infections, it is necessary to improve perineal hygiene for those whose infections are caused by bacteria normally found in feces, for which they may be recommended sitz baths. Often it helps to allow the genital area is more airy, using cotton underwear (rather than nylon) or underwear with cotton lining in the crotch area allows greater air flow and decreases amount of moisture in the area. It can also be helpful to sleep without underwear.

Note: If you are diagnosed with a sexually transmitted disease, it is very important that both partners receive treatment also, even if symptoms are present. Many organisms do not produce noticeable symptoms. The refusal of the (s) partner (s) to accept treatment can cause continual reinfection, which may eventually (if neglected) lead to more extensive problems, possibly limiting fertility and affecting overall health.

Expectations (prognosis)

Proper treatment of the infection is usually very effective.
Complications

* Persistent discomfort
* Skin infection (from scratching)
* Complications of causal condition (such as gonorrhea and candida infection)

Calling your health care

Call your doctor if symptoms of vulvovaginitis or if known vulvovaginitis does not respond to treatment.

Prevention

The use of a condom during sexual intercourse can prevent most sexually transmitted vaginal infections. The use of fitting and adequately absorbent clothing, combined with good hygiene of the genital area also prevents many cases of non-infectious vulvovaginitis.

Children should be taught how to properly clean the genital area while bathing or showering. Will also help clean properly after using the toilet (girls should always wipe from front to back to avoid introducing bacteria from the rectal area to the vagina).

Hands should be washed thoroughly before and after using the bathroom.

Vaginitis, vaginal inflammation, inflammation of the vagina

Iodine in diet

Iodine is naturally found in the body and it is an essential element.

Functions

Iodine is necessary for the metabolism (the process of converting food into energy) normal cells. Humans need iodine for normal thyroid function and the production of thyroid hormones.

Food Sources

Iodized salt, salt with iodine added, "is the main food source of iodine. Iodine is found naturally in seafood, and also cod, sea bass, haddock and perch are good sources. The brown algae or marine (kelp) is the most common vegetable seafood and features a rich source of iodine. In addition, dairy products and plants grown in iodine rich soils are excellent sources of this nutrient.

Side Effects
Lack of enough iodine (deficiency) may occur in areas with poor soils in this element. Iodine deficiency in the diet for several months can cause goiter or hypothyroidism. Without enough iodine, the thyroid cells and thyroid gland enlarged.

This deficiency most often affects women than men and is more common in pregnant women and children. Sufficient iodine intake in the diet can prevent a form of physical and mental retardation called cretinism, a condition rare in the United States, since deficiency of iodine, usually not a problem.

Iodine poisoning in the United States is rare. The high consumption of this element can reduce the function of the thyroid gland.



Recommendations

The best way to get the daily requirement of essential vitamins is to eat a balanced diet containing a variety of foods from the pyramid of basic food groups.

A 1 / 4 teaspoon of iodized table salt provides 95 micrograms of iodine. A serving of 6 ounces (170 grams) of sea fish provides 650 micrograms of iodine. Most people can meet the daily recommendations by eating seafood, iodized salt and plants grown in iodine rich soils. When buying salt make sure it is labeled "iodized."

The Food and Nutrition Committee of the Institute of Medicine (Food and Nutrition Board of the Institute of Medicine) recommends the following dietary intake for iodine:

Infants:

* 0 - 6 months: 110 micrograms per day (mcg / day)
* 7 to 12 months: 130 mcg / day

Children:

* 1 to 3 years: 90 mcg / day
* 4 to 8 years: 90 mcg / day
* 9 to 13 years: 120 mcg / day

Adolescents and Adults

* Men age 14 and older: 150 mcg / day
* Women age 14 and older: 150 mcg / day

Specific recommendations depend on age, sex and other factors (such as pregnancy). Women who are pregnant or producing milk (lactating) need higher amounts. Ask your doctor what amount is best for you.

Zinc in diet

Zinc is an important trace element that is second only to iron in its concentration in the body.

Functions

Zinc is necessary for the body's defense system (immune system) to work properly. Play a role in cell division and cell growth, as in wound healing and in the metabolism of carbohydrates. Zinc is also needed for the senses of smell and taste.

Food Sources

Protein-rich foods contain large amounts of zinc. Beef, pork and lamb contain more zinc than fish. The dark meat of chicken has more zinc than white meat.

Other good sources of zinc are peanuts, peanut butter and legumes.

Fruits and vegetables are good sources, because zinc in plant proteins is not as available for human consumption such as zinc from animal proteins. Therefore, low-protein diets and vegetarian diets tend to be low in zinc.

Side Effects

The symptoms of zinc deficiency include:

* Frequent infections
* Hypogonadism in men
* Hair loss
* Loss of appetite
* Problems with taste
* Problems with the sense of smell
* Slow growth
* Difficulty seeing in the dark
* Various skin lesions
* Wounds that are slow to heal

Zinc supplements in large amounts can cause diarrhea, abdominal cramps and vomiting, usually within 3 to 10 hours after ingestion. The symptoms disappear within a short period of time after discontinuing the supplements.



Recommendations

The best way to get the daily requirement of essential vitamins and minerals is to eat a balanced diet containing a variety of products from the pyramid of basic food groups.

The Food and Nutrition Committee of the Institute of Medicine (Food and Nutrition Board of the Institute of Medicine) recommends the following dietary intake for zinc:

Infants:

* 0-6 months: 2 milligrams per day (mg / day)
* 7-12 months: 3 mg / day

Children:

* 1-3 years: 3 mg / day
* 4-8 years: 5 mg / day
* 9-13 years: 8 mg / day

Adolescents and Adults

* Males age 14 and older: 11 mg / day
* Women age 14 to 18 years: 9 mg / day
* Women age 19 and older: 8 mg / day

Specific recommendations depend on age, sex and other factors (such as pregnancy). Women who are pregnant or producing milk (lactating) need higher amounts. Ask your doctor what amount is best for you.

Alternative Names
A-Th3; AT III

Definition

It is a blood test that measures the amount of antithrombin III (AT III), a protein that helps control blood clotting.

Manner in which the examination is performed

Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with a disinfectant (antiseptic). The doctor places a rubber band around the upper arm to apply pressure on the area and cause the vein to fill with blood.

Then the doctor inserts a needle gently into the vein and blood collected in an airtight jar or a tube affixed to the needle. The elastic band is removed from the arm.

Once you have collected the blood sample is withdrawn and covers the needle puncture site to stop any bleeding.

In infants or young children, you can use a pointed instrument called a lancet to puncture the skin and make it bleed. The blood is collected in a small glass tube called a pipette, in a slide or a strip. Finally, we can put a bandage on the area if there is any bleeding.

Preparation for the review

It is possible that the doctor will ask the person to suspend or reduce the dose of certain medications before the procedure, some of which can affect the outcome of the review. However, one should not stop taking any medication without first talking to your doctor.

What you feel during the test

When a needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or sting sensation. Subsequently, there may be some pulsating sensation.

Reasons for which the examination is performed Back to top

The doctor may order this test if there is blood clots in repetitive or anticoagulant drugs do not work.



Normal Values

The ranges of normal values may vary slightly among different laboratories. Talk to your doctor about the meaning of the specific results of its review.

Significance of abnormal results

Antithrombin III levels lower than normal may mean that you have an increased risk of clotting and abnormal results may not appear to be an adult.

Examples of disorders and conditions associated with increased blood clotting may include:

* Deep vein thrombosis
* Phlebitis (inflammation of a vein)
* Pulmonary embolism (blood clot that travels to the lung)

Antithrombin III levels lower than normal may be due to:

* Bone Marrow Transplant
* DIC (disseminated intravascular coagulation)
* Other coagulation disorders
* A hereditary condition that causes lower levels of the protein in blood clotting
* Liver
Nephrotic Syndrome *

Antithrombin III levels higher than normal may be due to:

* Use of anabolic steroids

What are the risks

* Excessive Bleeding
* Fainting or dizziness
* Hematoma (blood accumulating under the skin)
* Infection (a slight risk any time that this break in the skin)
* Multiple punctures to locate veins

Special considerations

The use of contraceptive pills may cause a slight decrease in the levels of AT III.

Veins and arteries vary in size from one patient to another and from one side to another, therefore, may be more difficult to obtain a blood sample from some people than others.
