| ==Treatment==
| |
| Medical treatment of Graves' disease includes antithyroid drugs, radioactive [[iodine]] and [[thyroidectomy]] (surgical excision of the gland).
| |
|
| |
| Treatment of the hyperthyroidism of Graves disease may be with medications such as carbimazole, methimazole or [[propylthiouracil]] (PTU), which reduce the production of [[thyroid hormone]], or with [[radioiodine|radioactive iodine]]. Surgical removal of the thyroid is another option, but still requires preoperative treatment with methimazole or PTU. This is done to render the patient "euthyroid" (i.e. normothyroid) before the surgery since operating on a frankly hyperthyroid patient is dangerous. Therapy with radioactive iodine (I-131) is the most common treatment in the United States. Thyroid blocking drugs and/or surgical thyroid removal is used more often than radioactive iodine as definitive treatment in Europe, Japan, and most of the rest of the world.
| |
|
| |
| The development of radioactive iodine (I-131) in the early 1940s at the [[Mallinckrodt General Clinical Research Center]] and its widespread adoption as treatment for Graves' Disease has led to a progressive reduction in the use of surgical thyroidectomy for this problem. In general, RAI therapy is effective, less expensive, and avoids the small but definite risks of surgery. Treatment with antithyroid medications must be given for six months to two years, in order to be effective. Even then, upon cessation of the drugs, the hyperthyroid state may recur. Side effects of the antithyroid medications include a potentially fatal reduction in the level of white blood cells.
| |
|
| |
| ===Antithyroid drugs===
| |
| The main antithyroid drugs are [[methimazole]] (US), [[carbimazole]] (UK) and [[propylthiouracil]]. These drugs block the binding of iodine and coupling of iodotyrosines. The most dangerous side-effect is [[agranulocytosis]] (1/250, more in PTU); this is an idiosyncratic reaction which does not stop on cessation of drug. Others include [[neutropenia|granulocytopenia]] (dose dependent, which improves on cessation of the drug) and [[aplastic anemia]]. Patients on these medications should see a doctor if they develop sore throat or fever. The most common side effects are rash and peripheral neuritis. These drugs also cross the [[placenta]] and are secreted in breast milk.
| |
|
| |
| ===Radioiodine===
| |
| This modality is suitable for most patients, although some prefer to use it mainly for older patients. Indications for [[radioiodine]] are: failed medical therapy or surgery and where medical or surgical therapy are contraindicated.
| |
|
| |
| Contraindications to RAI are [[pregnancy]] (absolute), ophthalmopathy (relative- it can aggravate thyroid eye disease), solitary [[thyroid nodule|nodules]]. Disadvantages of this treatment are a high incidence of [[hypothyroidism]] (up to 80%) requiring hormone supplementation. It acts slowly and has a relapse rate that depends on the dose administered.
| |
|
| |
| ===Surgery===
| |
| This modality is suitable for young patients and pregnant patients. Indications are: a large goiter (especially when compressing the [[vertebrate trachea|trachea]]), suspicious nodules or suspected [[cancer]] (to pathologically examine the thyroid) and patients with ophthalmopathy.
| |
|
| |
| Both bilateral subtotal thyroidectomy and the Hartley-Dunhill procedure (hemithyroidectomy on 1 side and partial lobectomy on other side) are possible.
| |
|
| |
| Advantages are: immediate cure and potential removal of [[carcinoma]]. Its risks are injury of the [[recurrent laryngeal nerve]], [[hypoparathyroidism]] (due to removal of the [[parathyroid gland]]s), [[hematoma]] (which can be life-threatening if it compresses the trachea) and scarring.
| |
|
| |
| ===Herbal===
| |
| For treating Graves disease, along with many other thyroid disorders, one can use the herb bugleweed. This herb has a profound effect on thyroid function and regulation of thyroid hormones.
| |
|
| |
| ===Eye disease===
| |
| Thyroid-associated ophthalmopathy is one of the most typical symptom of Graves Disease. It is known by a variety of terms, the commonest being [[Graves ophthalmopathy]]. Thyroid eye disease is an inflammatory condition which affects the orbital contents including the extraocular muscles and orbital fat. It is almost always associated with Graves' disease but may rarely be seen in Hashimoto's thyroiditis, primary hypothyroidism, or thyroid cancer.
| |
|
| |
| The ocular manifestations include soft tissue inflammation, eyelid retraction, proptosis, corneal exposure, and optic nerve compression. The signs and symptoms of the disease are characteristic. These include lid retraction, lid lag, and a delay in the downward excursion of the upper eyelid in down gaze that is specific to thyroid-associated ophthalmopathy.
| |
|
| |
| *For mild disease - artificial tears, steroid eyedrops, oral steroids (to reduce chemosis)
| |
| *For moderate disease - lateral [[tarsorrhaphy]]
| |
| *For severe disease - orbital decompression or retro-orbital radiation

| ==Pathological Findings: A Case Example==
| |
| ===Clinical Summary===
| |
| An 18-year-old girl presented with complaints of swelling in the neck, weight loss, bulging of the eyes, tremor, decreased heat tolerance, loose stools, and occasional palpitations. Physical examination revealed normal blood pressure, resting tachycardia of 110 beats per minute, mild exophthalmos, eyelid lag, and a diffusely enlarged thyroid gland. Pertinent laboratory findings were thyroxine (T4) level 30.8 mcg/dL, free thyroxine was 2.7 ng/dL, and thyroid stimulating hormone (TSH) was 0.22 mcIU/mL. She was given propylthiouracil until she became nearly euthyroid, at which time a thyroidectomy was done.
| |
|
| |
| ===Autopsy Findings===
| |
| The thyroid gland weighed 45 grams. It was beefy red in color and had a homogeneous fleshy consistency.
