1/299. Thyroid function in early sub-acute thyroiditis.

    A 53-year-old woman with an early form of de Quervain's disease involving both thyroid lobes was found to have her thyroid uptake of iodine suppressed, although the serum thyroid hormone concentrations were normal while the administration of TRH resulted in significant increase in the serum TSH concentrations. After administration of TSH the thyroid reserve was found to below. The diagnosis of sub-acute thyroiditis was confirmed on biopsy. The above data seem to indicate that the suppression of the thyroid uptake in the early stage of de Quervain's disease may be directly caused by the inflammatory condition of the gland, rather than, as is usually the case, by the excess of thyroid hormones and, consequently, by the suppression of pituitary TSH secretion.

2/299. Riedel's thyroiditis.

    Riedel's thyroiditis is a rare chronic inflammatory disease of unknown aetiology and may be one manifestation of multifocal fibrosis. Four patients were seen over a period of 12 years and unusual presentations in 3 of them caused difficulty in diagnosis. The aetiology and methods of treatment are discussed. ( info)

3/299. Idiopathic retroperitoneal fibrosis in multifocal fibrosclerosis.

    A case of rare combination of retroperitoneal fibrosis and Riedel's thyroiditis is presented. The term multifocal fibrosclerosis is used in the literature to denote such combination and others which include idiopathic retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, invasive (Riedel's) thyroiditis and pseudotumor of the orbit.

4/299. Autoimmune thyroiditis and myelosuppression following treatment with interferon-alpha for hepatitis c.

    CASE: We describe the case of a 48-year-old woman from thailand diagnosed with chronic hepatitis c, who experienced a suppression of all blood cell counts accompanied by a newly developed clinically manifested autoimmune thyroid disorder after treatment with interferon alpha-2b (INF-alpha) 46 days after beginning of therapy a decrease of platelet, red and white blood cell counts became obvious. Concomitantly we observed an increase of FT4 and FT3 with a totally depressed TSH level 80 days after starting INF-alpha administration. Antibody assessment resulted in detection of high numbers of antithyroid-microsomal antibodies and antithyroglobulin antibodies. Thyroid hormone levels normalized under treatment with methimazole/propylthiouracil within 4.5 months. However, two months after cessation of antithyroid therapy increasing TSH levels and decreasing FT4 levels indicated a new tendency towards a hypothyroid state. CONCLUSION: We classify this case as an interferon-alpha-induced disorder of thyroid function accompanied by myelosuppression. A close monitoring for thyroid dysfunction, e.g. evaluation of TSH-levels before and after administration of INF-alpha is mandatory. ( info)

5/299. acanthosis nigricans with severe obesity, insulin resistance and hypothyroidism: improvement by diet control.

    We report on a 27-year-old man with acanthosis nigricans (AN) associated with severe obesity, insulin resistance and hypothyroidism. A very low-calorie diet treatment decreased his weight and then ameliorated the insulin-resistant state. These effects were followed by remarkable improvement of the AN prior to the correction of the hypothyroidism. This confirms that AN may be mainly attributed to insulin resistance rather than hypothyroidism per se. ( info)

6/299. Ob-Gyn interactive case challenge--a case of sadness and anxiety 9 months postpartum.

    If you were the primary care provider, how would you diagnose and treat postpartum anxiety and depression in this young, first-time mother? After a normal, uncomplicated pregnancy, this 27-year-old woman developed anxiety and depressed mood, which she was still struggling to control 9 months after the birth of her child. Among the diagnostic possibilities to consider are occult malignancy, diabetes mellitus, and thyroid disorder, as well as major depression/anxiety disorder and postpartum depression. ( info)

7/299. Primary biliary cirrhosis associated with painless thyroiditis.

    A case of anti-mitochondrial antibody (AMA)-negative primary biliary cirrhosis (PBC) associated with painless thyroiditis is reported in a 47-year-old woman who diagnosed as PBC based on her elevated serum gamma-glutamyl transpeptidase and immunoglobulin m levels, as well as histological findings of destroyed bile ducts surrounded by mononuclear infiltrates in the biopsied liver. She was negative for AMA and had a depressed level of thyroid-stimulating hormone accompanied by increased free thyrosine, thyroxine and triiodothyronine levels and low titers of anti-microsomal and anti-thyroid peroxidase antibodies. Her thyroid disorder corresponded with painless thyroiditis. An association between PBC and hyperthyroidism is rare. Furthermore, an association between AMA-negative PBC and hyperthyroidism due to painless thyroiditis has not previously been reported. ( info)

8/299. Nocardia thyroiditis: unusual location of infection.

    nocardia asteroides complex is an important opportunistic agent in immunocompromised hosts. Usually, primary pulmonary infection occurs and is followed by dissemination of the pathogen to the central nervous system and soft tissues. As described in the literature, almost every organ can be infected, but to our knowledge, Nocardia has been described as a pathogen responsible for thyroid abscess in only one report, which was published in 1993. The present report is the second case report of Nocardia thyroiditis. The patient was under immunosuppressor treatment following a combined liver-kidney transplant and presented with a preexisting nodular goiter which was probably a predisposing factor to the start and development of the thyroid infection.

9/299. hypoparathyroidism secondary to Riedel's thyroiditis. A case report and a review of the literature.

    Riedel's thyroiditis is a rare condition in which the thyroid gland is replaced by fibrous tissue. Fibrosis in various distant sites is a possible concomitant event. We report a case of Riedel's thyroiditis complicated by mediastinal fibrosis, a tumefactive fibro-inflammatory lesion of the neck and primary hypothyroidism. A review of the literature in which only 8 previous cases of hypoparathyroidism secondary to Riedel's thyroiditis have been recounted concludes the report. ( info)

10/299. Riedel's thyroiditis associated with follicular carcinoma.

    Riedel's thyroiditis is an uncommon disorder of unknown etiology that is characterized by an invasive fibrotic process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation as a stony-hard, poorly defined enlargement over the thyroid gland and local compression of the trachea, esophagus and recurrent laryngeal nerve can mimic invasive thyroid carcinoma. Because Riedel's thyroiditis is a self-limiting disease, its management should be conservative. However, invasive cancer such as follicular carcinoma can occur in association with Riedel's thyroiditis. Such a concurrence completely changes the focus of management. We report a case of Riedel's thyroiditis that was found in a patient with a follicular carcinoma. The strategy of management is discussed together with a review of the relevant literature. ( info)
