Thyroidolody, the study of the thyroid gland, is considered to be a relatively new field of endocrinology. However, references to the thyroid gland and its diseases can be seen in the literature of ancient Greek, Indian and Egyptian medicine. Goiter has always been a disease of immense interest of the general population due to its widespread prevalence. It is one of the most common medical problems portrayed in ancient paintings. Owing to the lack of awareness and poor nutritious habits of the people in that era, diseases such as iodine deficiency goiter were common. Physicians, healers and philosophers had been attempting time and again until the 19 th century to come up with explanations of the thyroid gland and provide a reasonable basis of its diseases.
The U. Food and Drug Administration is tightening the potency specifications for levothyroxine sodium, used to treat underactive thyroid glands and other thyroid conditions, to ensure the drug retains its potency over its entire shelf life. This action is being taken in response to concerns that the potency of the drug may deteriorate prior to its expiration date. The change will help improve the quality of the product so that consumers receive the level of medication needed to treat their thyroid disorders.
Levothyroxine sodium products are used by over 13 million patients. FDA is mandating that levothyroxine sodium drug products tighten their potency specifications to meet a 95 percent to percent potency specification until their expiration date.

ANNE M. Female residentS of western Washington state aged 18—80 years in whom thyrold cancer was diagnosed between January and December were interviewed concerning their reproductive histories and their prior use of exogenous estrogens. Their responses were compared with those of a sample of women from the same population, individually matched to cases on tele phone prefix. Use of each of several estrogen-containing preparations was associated with a small increased risk of thyroid cancer; parous women who had ever used a lactation suppressant had 1.
Among the low risk group of women, i. However, no increase in risk with increasing duration of use of oral contraceptives or menopausal estrogens or with increasing number of pregnancies was noted.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. Thyrotoxicosis was the biochemical and physiological manifestations of excess thyroid hormone. The clinical manifestation was palpitation, heat intolerance, hand tremor, and weight loss. The clinical manifestation also included nervous system, including anxiety, tension, irritability, hyperactivity, fatigue, and insomnia.
Where tensions features include restless, short attention span, and the impulse to want to move around. Some patients will progress to a non-specific psychiatric disorders.

Your thyroid is a small, butterfly-shaped gland which weighs less than an ounce. It perches unobtrusively with its wings wrapped around the front of your windpipe trachea , below your voice box larynx. Despite its slight size, your thyroid controls the rate at which every cell, tissue, and organ in your body functions, from your muscles, bones, and skin to your digestive tract, brain, heart, and more.
It does this primarily by secreting hormones that control how fast and efficiently cells convert nutrients into energy—a chemical activity known as metabolism—so that the cells can perform their functions. Just as your car engine can’t run without gasoline, your thyroid needs fuel to produce thyroid hormone. This fuel is iodine. Iodine is found in such foods as iodized table salt, seafood, bread, and milk. When you eat these foods, the iodine passes into your bloodstream.
Your thyroid then extracts this necessary ingredient from your blood and uses it to make two kinds of thyroid hormone: thyroxine, called T4 because it contains four iodine atoms, and triiodothyronine, or T3, which contains three iodine atoms. The thyroid’s output consists primarily of T4. Most of the T3 the body needs is created outside the thyroid in organs and tissues that use T3, such as the liver, kidneys, and brain. These tissues convert T4 from the thyroid into T3 by removing an iodine atom.
We report a case of toxoplasmosis lymphadenitis simulating a parotid mass concurrent with a papillary thyroid carcinoma. A year-old male presented symptomless masses in the left lower neck and right preauricular region for 2 months. Computed tomography confirmed a lobulated nodule, embedded in the right parotid gland, and; a left thyroid nodule, which resembled a papillary thyroid carcinoma. Fine-needle aspiration FNA of the left thyroid lobe suggested a papillary thyroid carcinoma.
A radical thyroidectomy, central neck lymph node dissection, and right superficial parotidectomy were performed. Histopathological examination of the surgical specimen supported the diagnosis of a papillary carcinoma of the left thyroid lobe and toxoplasmosis lymphadenitis in the right parotid gland.

Lisa Haber, now 41, struggled with weight issues , fatigue , and dry skin as a teenager. She visited an endocrinologist, who said her thyroid was not to blame. But in , when she was 37 and trying unsuccessfully to get pregnant , she went to her internist and had her thyroid retested. She found out that it wasn’t actually functioning well, and could be contributing to her inability to have a baby. Lisa, a social worker who lives in Chicago, went on medication that relieved some of her symptoms, and she became pregnant with her son a few months later.
Thyroid problems can take a toll on well-being, and as Lisa found out, they can be difficult to pinpoint. Often the symptoms mimic signs of other issues like depression and menopause. About one in eight women will develop a thyroid disorder during her lifetime, according to the American Thyroid Association ATA , yet up to 60 percent of people with thyroid disease don’t realize they have it. What’s more, the diagnosis of hypothyroidism , one of the most common thyroid problems, can be controversial: Some experts think test results don’t always offer a definitive answer.
That’s why you should educate yourself to stay healthy. Here, what all women need to know. The butterfly-shaped gland, which lives in the base of your neck, is frequently associated with everything from fatigue to excess pounds — for good reason.

The thyroid, or thyroid gland, is an endocrine gland in the neck consisting of two connected the ancient Greek shield of a similar pronunciation. Shown is an example of such a shield, as engraved on an obol, dating from – BCE.
There is a poignant before and after photolithograph of a Victorian lady in the transactions of the Royal Medical and Chirurgical Society of London Figure 1 Ord This is not the usual celebratory image before and after successful treatment. It is a picture of the woman, aged 21 in , and then seven years later, unrecognisably aged by the effects of undiagnosed and untreated thyroid deficiency.
It is poignant because she probably dies of the disease, the introduction in of effective treatment with subcutaneous injections of thyroid extract by George Murray of Newcastle-upon-Tyne coming too late Murray a. A number of steps led to the discovery of thyroid replacement therapy: the slow understanding that this debilitating disease, myxoedema, was in some way linked to the thyroid; the acceptance of the notion that the thyroid elaborated some important factor with an endocrinefunction; the emergence of the principle of replacement therapy: and the introduction of replacement therapy in practice.
But, contrary to general belief, Murray was not the first to treat myxoedema effectively. The history of the thyroid gland goes back millennia. Its long history is inseparable from that of goitre — Latin guttur , neck or throat — for there must always have been people with goitrous swollen necks. August Hirsch in his monumental three-volume work, Handbook of Geographical and Historical Pathology , provides many past references worldwide to endemic goitre and endemic cretinism, notably prevalent in mountain valley regions but absent in coastal regions Hirsch Amongst these — and suggestive evidence of a general public awareness of goitre — is Juvenal in the early 2 nd century CE asking rhetorically: Quis tumidum guttur miratur in Alpibus [ Who wonders at a swollen neck in the Alps].
Rolleston quotes a source in describing an incident involving an English traveller in the Tyrol of whom it was remarked that he would have been quite handsome if only he had had a goitre, such was the almost universal presence of goitre in that region Rolleston , presumably a long-standing feature.
The thyroid is a small gland below the skin and muscles at the front of the neck, at the spot where a bow tie would rest. It makes two types of thyroid hormones: T3 triiodothyronine and T4 thyroxine. It helps the body do many things, such as get energy from food, grow, and go through sexual development. The pituitary is a pea-sized gland at the bottom of the brain that makes thyroid stimulating hormone TSH. TSH triggers the thyroid to make more thyroid hormone.

Guldvog I, et al. Ann Intern Med. Participants were recruited between Feb. The follow-up period for the trial was 18 months, with visits every 3 months. Researchers measured serum antithyroid peroxidase anti-TPO antibody titers and thyroid-stimulating hormone, free thyroxine, free triiodothyronine, calcium and parathyroid hormone levels during follow-up. Higher scores indicated worse health measures.
The researchers also found improvements in reported levels of fatigue in participants who underwent thyroidectomy. Disclosure s : Guldvog reports no relevant financial disclosures.
