1/27. Eosinophilic fasciitis associated with autoimmune phenomena after bone marrow transplantation: report of two cases.Between January 1992 and May 2004, 189 patients underwent allogeneic bone marrow transplantation (BMT) for haematological malignancies from HLA-identical sibling donors in our transplantation unit. Of the 189 patients, 2 developed eosinophilic fasciitis (EF). The first patient developed Hashimoto's thyroiditis and EF 11 and 21 months after BMT, respectively. In the second patient EF occurred 9 months after BMT, accompanied by antinuclear antibodies, antiextractable nuclear antigens and antigliadin antibodies. Both patients were treated with extracorporeal photochemotherapy (ECP), resulting in improvement of fasciitis in both and normalization of antithyroid antibodies in the first patient. Our data confirm the rarity of fasciitis after BMT and the efficacy of ECP, recently applied experimentally in one patient for the treatment of fasciitis after BMT. Moreover, we report for the first time the association of fasciitis with autoimmune phenomena after BMT. The correlation between the two entities is supported by remission of Hashimoto's thyroiditis after ECP treatment for fasciitis.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
2/27. Cerebellar subacute syndrome due to corticosteroid-responsive encephalopathy associated with autoimmune thyroiditis (also called "Hashimoto's encephalopathy").The corticosteroid-responsive encephalopathy associated with autoimmune thyroiditis (the so-called "Hashimoto's Encephalopathy") is a rare disorder with multiple symptomatology, breaking out with an acute or subacute onset and having a relapsing course, not correlated to thyroid hormone levels, with autoimmune pathogenesis, and usually associated with Hashimoto's thyroiditis. In this paper, we report on a case study regarding a 46 year-old woman showing a subacute course cerebellar syndrome, associated with Hashimoto's thyroiditis, diagnosed as "Hashimoto's encephalopathy". The possible pathogenesis and the major aspects of the differential diagnostic sector are discussed with particular reference to an ataxic syndrome caused by a progressive non-familial adult onset cerebellar degeneration (PNACD), associated with the thyroid disease itself.- - - - - - - - - - ranking = 3keywords = thyroid (Clic here for more details about this article) |
3/27. multiple sclerosis and Hashimoto thyroiditis: two cases.multiple sclerosis (MS) occurs with immune-mediated mechanisms, but its pathogenesis is not accurately known. The coexistence of MS with other autoimmune diseases has been reported. The hypothesis that MS coexists with other autoimmune diseases has been supported by the reported association of MS with type I diabetes mellitus and inflammatory disorders. Even though there have been only rare reports of associations between Hashimoto thyroiditis and MS, this association is important for its clinical and therapeutic aspects. Proximal muscle weakness, myalgia, and fatigue are symptoms that are common in both MS and hypothyroidism. When MS patients demonstrate these symptoms, thyroid function tests should be performed. The thyroid hormone levels of MS patients being treated with interferon-beta and Campath-1H also should be monitored. The authors report the clinical data of 2 definite MS patients who also fulfilled criteria for Hashimoto thyroiditis.- - - - - - - - - - ranking = 3keywords = thyroid (Clic here for more details about this article) |
4/27. Hashimoto encephalopathy with pegylated interferon alfa-2b and ribavirin.OBJECTIVE: To report an instance of Hashimoto encephalopathy probably resulting from pegylated interferon alfa-2b and ribavirin. CASE SUMMARY: A 36-year-old woman with a 10-year history of autoimmune thyroiditis presented with symptoms and signs consistent with Hashimoto encephalopathy during therapy with pegylated interferon alfa-2b and ribavirin for chronic hepatitis c. DISCUSSION: Hashimoto encephalopathy is a rare autoimmune condition that occurs in patients with Hashimoto thyroiditis and high titers of antithyroid antibodies. It is characterized by a variety of nonspecific neuropsychiatric symptoms, increased cerebrospinal fluid protein level, and abnormal brain imaging and electroencephalogram. Prompt response to corticosteroids is observed in most cases. As of August 29, 2005, this is the first report of such an association. An objective causality assessment revealed that the Hashimoto encephalopathy was probably caused by the patient's medications. CONCLUSIONS: Hashimoto encephalopathy may rarely be triggered by interferon alfa therapy in susceptible patients.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
5/27. cardiac tamponade in Hashimoto's disease.Myxedematous pericardial effusions, occurring in about one-third of patients with hypothyroidism, usually do not cause symptoms and regress slowly with hormonal treatment.

6/27. Primary thyroid lymphoma: a report of two cases.Primary thyroid lymphomas (PTLs) are rare neoplasms which in the past have been classified by various schemes. Clinicopathological findings of two cases which were diagnosed in the past one year in our institute are presented using the Revised European and American classification (REAL) for lymphomas. Both cases presented as enlarging neck masses in elderly female patients, in association with lymphocytic thyroiditis. One case was diagnosed as a MALT (mucosa associated lymphoid tissue) lymphoma while the other was a diffuse large cell lymphoma (DLCL).- - - - - - - - - - ranking = 2keywords = thyroid (Clic here for more details about this article) |
7/27. A case of overlap syndrome with rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis and secondary sjogren's syndrome.We report an unusual case of overlap syndrome that had the coexistence of five autoimmune diseases. A 45-year-old woman initially developed seropositive erosive rheumatoid arthritis (RA) 11 years ago. She then developed progressive systemic sclerosis (PSS) (including pulmonary hypertension, esophageal dysfunction, cardiac involvement and sclerodactilitis), systemic lupus erythematosus (SLE) (including photosensitivity, nephritis, leukopenia, lymphopenia, thrombocytopenia and Coombs positive hemolytic anemia and positive anti-dsDNA), and secondary sjogren's syndrome (SSS) in the last 7 years before she was admitted to our clinic. The patient fulfilled classification criteria for RA, SLE, PSS and SSS, as determined by American College of rheumatology. hypothyroidism with positive autoantibodies due to Hashimoto's thyroiditis, the beginning of which could not be defined, was coexistent with this overlap syndrome. In the literature, although overlap syndromes in different combinations were reported, we very rarely observed a complex case like this patient. In our opinion, this is the first well-documented case of RA, PSS, SLE, SSS and Hashimoto's thyroiditis existing together in the same patient. Although immunosuppressive therapy was administered, the disease rapidly deteriorated and the patient died.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
8/27. Recurrent status epilepticus as the main feature of Hashimoto's encephalopathy.Hashimoto's encephalopathy (HE) is a severe but treatable condition that rarely complicates Hashimoto's thyroiditis. Clinically it is characterized by progressive or relapsing symptoms, including tremor, myoclonus, stroke-like episodes, seizures, impairment of consciousness, and dementia. We describe a patient presenting with recurrent generalized convulsive status epilepticus (GCSE), despite antiepileptic medications, who was successfully treated with methylprednisolone. Our observation confirms that the clinical spectrum of HE at presentation is heterogeneous and diagnosis is often difficult. This case highlights the crucial importance of antithyroid antibody measurement in patients presenting with otherwise unexplained episodes of GCSE with or without adjunctive signs of encephalopathy or thyroiditis.- - - - - - - - - - ranking = 1keywords = thyroid (Clic here for more details about this article) |
9/27. Massive squamous metaplasia of the thyroid gland-- report of three cases.Three cases of massive squamous cell metaplasia in Hashimoto's thyroiditis are reported. The patients were two men and one woman aged 24, 52, and 55 years, respectively. In all three patients, the glandular parenchyma was replaced by hypocellular fibrous tissue with scattered chronic inflammatory infiltrate. Follicular cells were almost absent; the majority of residual epithelial cells formed squamous nests that were partly solid and partly cystic. There were three types of epithelial cells - squamous, basaloid, and follicular, with oncocytic differentiation. The squamous and basaloid cells showed strong positivity high molecular weight (HMW) cytokeratin, moderate to strong expression of galectin-3 (2/3), and nuclear expression of p63 protein (2/3). The staining pattern of p63 was identical to that of HMW, with predominant positivity at the periphery of cell nests. In one case, weak but unequivocal positivity of thyroid transcription factor-1 also was present. We believe that metaplasia was caused by Hashimoto's thyroiditis. The cases presented here are extremely rare, and only two convincing similar cases have been reported in the English literature so far. They may represent a diagnostic pitfall and should not be misdiagnosed as a malignancy, in particular as squamous cell or mucoepidermoid carcinoma.- - - - - - - - - - ranking = 2.3333333333333keywords = thyroid (Clic here for more details about this article) |
10/27. Graves' disease and Hashimoto's thyroiditis in monozygotic twins: case study as well as transcriptomic and immunohistological analysis of thyroid tissues.OBJECTIVE: To report on the rare simultaneous occurrence of Graves' disease (GD) and Hashimoto's thyroiditis (HT) in monozygotic twins. DESIGN: We compared the pattern of thyroid tissue-derived cDNAs to gain insight into previous and ongoing immune destruction and reconstruction processes using microarrays. The results were confirmed by immunohistology and real-time PCR. RESULTS: Destruction of thyroid tissue in HT reduced levels of thyrocyte-related cDNAs and cDNAs encoding extracellular matrix components, but increased levels of proteases involved in extracellular matrix degradation compared with GD. Lymphocytic infiltrates forming ectopic follicles replaced the thyroid tissue almost completely in HT. Thus, lymphocyte-related cDNA levels were higher in HT than in GD. The same was true for many chemokines and their receptors, which not only enable migration towards the thyroid but also maintain the lymphocytic infiltrate. HT also showed increased levels of cDNAs encoding molecules related to apoptosis than did GD. Surprisingly, the Th1- and Th2-specific cytokine profiles suggested for HT and GD respectively could not be confirmed. cDNAs encoding factors and receptors involved in angiogenesis were increased in GD compared with HT. CONCLUSIONS: Comparison of gene expression reflects the cellular differences between the two types of autoimmune thyroid disease in twins with identical genetic and similar environmental background.- - - - - - - - - - ranking = 4.6666666666667keywords = thyroid (Clic here for more details about this article) |
