Thyroid

The thyroid is responsible for controlling your metabolism, blood calcium levels, energy, excess fats, hormones, oxygen, weight loss. Blood tests can determine your TSH levels to see if you thyroid gland is functioning properly. If you have an under-active thyroid, you are said to have hypothyroidism. If you have an overactive thyroid, you are said to have hyperthyroidism. The thyroid can also be related to several other conditions such as Grave's Disease and heart problems.

What is your thyroid gland like?

Yes! a thyroid gland IS an endocrine gland

What is a tsh of 0.52?

The Thyroid Stimulating Hormone or TSH test is used to test problems associated with thyroid disorders

What is thyroid?

The thyroid is a gland just beneath the larynx in your neck. It produces what are known as thyroid hormones which are involved in oxygen consumption in adults and regulation of growth and development in children.

By what measure is thyroid storm a fatal disorder?

Mortality from thyroid storm, an uncommon complication of thyroidectomy, is in the range of 20-30%.

Why does the thyroid gland have such a rich blood supply?

because of the blood cells in the brain sending messages

How many milligrams of armour thyroid does a person without a thyroid normally take?

Thyroid supplementation is very individualized. There is no one specific dosage for adults or children. Patients are tested and examined frequently until their labs improve and their symptoms are minimized.

How you came to know that thyroid gland is cancerous or not?

Just like men and women are encouraged to do routine skin checks for abnormal growths, bumps and moles on the body, people can do a self-exam of the neck.

Known as a neck check, start by standing in front of a mirror or holding a hand held mirror. Next, get a glass of water.

As the American Association of Clinical Endocrinologists suggests in their neck check resources, hold the mirror focusing on the lower portion of the neck. Then take a drink of water and swallow. When swallowing, look at the neck for any bulges in this area. Repeat this process several times in order to not confuse any bumps with the Adam's apple. Any consistent abnormalities need to be discussed with a doctor.

A doctor will then evaluate any bulges. From there they will order further testing to better understand the health of the thyroid gland.

What disorder is the enlargement of the thyroid due to hypo or hyper secretion?

An enlarged thyroid gland is called a goiter. The disease of hypo or hyper secretion is known as hypothyroidism or hyperthyroidism.

Can you donate blood if you have Hashimoto's thyroiditis or Grave's disease?

If you have a thyroid autoimmune condition some online research suggests that you may or may not be able to give blood. According to the American Red Cross, the general rule is that if you're taking medication for maintenance of Hashitmoto's thyroiditis or Graves' disease then you can give blood. The Red Cross does advise to ask your doctor's opinion before giving blood, though.

If you have any questions about donating blood contact your local Red Cross chapter, or whomever is conducting the blood drive, to discuss their guidelines.

Can fritillaria cause side effects?

high-dosage intravenous injections of alkaloids isolated from fritillaria produced pupil dilation, tremor, slowing of the heart rate, and lowered blood pressure in human subjects.

What are the symptoms of goitre?

A goiter is the visible swelling of the thyroid gland. A patient may have a goiter and no physical symptoms other than the swelling itself.

How much Tc-99m given for thyroid scan?

10 mCi of Tc-99m is the dosage required for a thyroid scan

ENDOCRINE NUCLEAR MEDICINE

THYROID SCANINDICATIONS:
  1. Determination of thyroid size, function, and position.
  2. Evaluation of functional status of thyroid nodules.
  3. Evaluation of thyroid and neck masses.
  4. Evaluation of patients with history of head and neck irradiation.
  5. Quantitative thyroid uptake (I-131 uptake).
  6. Detection of ectopic thyroid tissues such as substernal or sublingual locations of thyroid tissue (I-123).
  7. Treatment for hyperthyroidism, neoplasm (I-131).
  8. Detection of thyroid metastases and assessment of response to therapy (I-131).
PATIENT PREPARATION:
  1. Patients are kept NPO for at least three hours before uptake studies. No fasting is required for Technetium scanning.
  2. Patients should be off iodine-containing drugs. This includes radiographic contrast! The minimum time interval between prior iodine administration and scanning varies from one week (e.g. iodine solution) to 3 weeks (Synthroid) to 2-10 years (oil-based Myelogram). If the patient has an IVP or a CT with IV contrast, a thyroid scan should not be attempted for 4-6 weeks. Many other medications interfere with scanning (PCN, antihistamines, etc.). Consult Nuclear Medicine for a complete list.
RADIOPHARMACEUTICAL:
  1. For Iodine Uptake 10-50 mCi of I-131 p.o. (uptake alone).
  2. For Technetium Pertechnetate 10 mCi Tc-99m pertechnetate given I.V.
  3. Metastatic Workup 5 mCi I-131 p.o.
  4. Therapy 5-30 mCi I-131 p.o. for hyperthyroidism.

75-300 mCi I-131 p.o. for cancer treatment.

The critical organ with iodine radiopharmaceuticals is the thyroid, which receives 1-2 rad from a typical I-123 uptake and scan. Doses for I-131 are considerably higher; I-131 ablation therapy dose, over 30 mCi, require hospitalization for proper isolation. 99mTcO4 gives 0.12-0.20 rad/mCi to the thyroid.

SCANNING TIME:For 99mTcO4 scanning is begun approximately 20 minutes after injection.

For metastatic workup - 48 and 96 hours post oral administration.

For thyroid uptake test -- 24 hours.

OTHER CONSIDERATIONS:
  1. In some institutions, I-123 is used for uptake and scan; I-131 is reserved for metastatic workup. I-131 is also used for treatment of hyperthyroidism and thyroid cancer. 99mTcO4 has the advantage of short time to scan and avoidance of second trip to the department, however, it cannot be used for evaluating thyroid uptake. Hot nodules with 99mTcO4 may require evaluation with iodine.
  2. Both agents (Tc, I) cross the placenta and are secreted in breast milk. Pregnancy is, therefore, a relative contraindication and breast feeding must be interrupted if scanning is necessary for 7 days with Tc-99m and should be terminated when using I-123 or I-131 (for that particular pregnancy).
  3. Iodine-containing preparations as well as several non-Iodine medications interfere with both 99mTcO4 and Iodine scans, Please consult the Nuclear Medicine Department prior to scanning. (See "patient preparation").
RATIONALE:Iodine is actively trapped, concentrated and organified by the thyroid gland. This is the basis for morphologic and functional imaging. The uptake study measures the percentage of the administered dose localizing in the gland at a fixed time; this reflects gland function. Technetium is also trapped by the thyroid, but is not organified. It washes out of the gland after peaking at approximately 20 min post injection. Therefore, it is not ideal for evaluating percent uptake. Normal range for 24 hour I-131 (and I-123) thyroid uptake is 7 to 33% in our laboratory.

Thyroid gland is kept healthy by taking which type of food?

The basics for a healthy diet supporting the thyroid gland includes :

* Iodine : a necessary mineral to help the thyroid gland make enough hormones * Low glycemic foods * Lean protein * Fiber * Vitamins and minerals

These are healthy guidelines for anybody trying to loose weight, but even more someone with low thyroid functions.

Nodules on the thyroid?

Nodules in the thyroid may be cancerous or benign. They may be *hot* (producing hormone) or *cold (not producing hormone).

15.0 in your thyroid levels means what?

A 15.0 thyroid doesn't give enough information. Please tell which thyroid test was run.

Can facial massage cause side effects?

Facial massage may irritate and worsen such skin conditions as acne, psoriasis or eczema.
