1/433. Manifestation of Hashimoto's encephalopathy years before onset of thyroid disease.patients with Hashimoto's encephalopathy (HE), a steroid-responsive disorder, associated with Hashimoto's disease and high levels of thyroid-related autoantibodies usually present with a subacute onset of confusion, focal or generalized seizures. Frequent EEG abnormalities include generalized, rhythmic bifrontal or temporal slowing. Elevated protein levels or an intrathecal IgG synthesis may be present in cerebrospinal fluid (CSF). A 39-year-old woman underwent a relapsing course of myocloni and generalized seizures. Initially, thyroid function, thyroid-related autoantibody screening and cerebral MRI were unrevealing. CSF showed oligoclonal bands. Short-term treatment with high doses of prednisolone resolved the myocloni. During the 5th episode of myocloni, signs of hyperthyroidism and elevation of thyroid microsomal antibody titer developed. Hashimoto's thyroiditis and HE were diagnosed. After subtotal thyroidectomy the patient remained asymptomatic.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
2/433. Reactive lymphoid hyperplasia of liver coexisting with chronic thyroiditis: radiographical characteristics of the disorder.BACKGROUND: Reactive lymphoid hyperplasia of the liver is an extremely rare entity, with six cases reported so far. methods: We encountered a 47-year-old Japanese female with reactive lymphoid hyperplasia of the liver, which coexisted with chronic thyroiditis. The lesion was discovered incidentally as a hypo-echoic mass with a hyper-echoic rim at a routine ultrasonography examination. It increased from 12 to 17 mm diameter in 6 months. Radiological studies, such as contrast-enhanced computerized tomography (CT) and angiography demonstrated a hypervascular lesion. RESULTS: It was consequently diagnosed as a neoplasm with malignant potentiality and she underwent partial hepatectomy. The lesion was composed of small mature lymphocytes which formed prominent lymphoid follicles with germinal centres, scattered plasma cells and stromal fibrosis. Immunohistochemical study revealed polyclonal origins of the involved lymphocytes. dna analysis for the immunoglobulin heavy gene and the T cell receptor beta gene using Southern blot hybridization showed no monoclonality. The following features have characterized the images in past cases, as well as ours: hypo-echoic mass, occasionally with a rim, in ultrasonography and hypervascularity, shown by angiography and enhanced CT.- - - - - - - - - - ranking = 5keywords = thyroiditis (Clic here for more details about this article) |
3/433. insulin dependent diabetes mellitus (IDDM) and autoimmune thyroiditis in a boy with a ring chromosome 18: additional evidence of autoimmunity or IDDM gene(s) on chromosome 18.A 4 year 3 month old boy with insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, slight mental retardation, facial dysmorphism, and a de novo ring chromosome 18 (deletion 18q22.3-18qter) is described. This unique association of defects could represent a chance association. Alternatively, the clinical features could be the result of the chromosomal aberration. If so, one could speculate that a gene or genes on chromosome 18 might act as a suppressor or activator of the autoimmune process by itself or in concert with other IDDM loci.- - - - - - - - - - ranking = 5keywords = thyroiditis (Clic here for more details about this article) |
4/433. Pseudogout attack associated with chronic thyroiditis and sjogren's syndrome.A 66-year-old woman, diagnosed with chronic thyroiditis at age 63, presented with anorexia and fatigue. Therapy for the chronic thyroiditis consisted of levothyroxine sodium (100 microg/day). Her symptoms were attributed to the insufficient supply of levothyroxine sodium. Following a dosage increase to 150 microg/day, she suffered from an acute attack of pseudogout. Clinical features were complicated by sjogren's syndrome, which appeared after treatment onset. Pseudogout was effectively treated by colchicine after administration of diclofenac sodium failed to alleviate the symptoms. Pseudogout is a recognized complication of thyroid replacement therapy, but association with sjogren's syndrome has not been previously reported.- - - - - - - - - - ranking = 6keywords = thyroiditis (Clic here for more details about this article) |
5/433. Hashimoto's encephalitis as a differential diagnosis of Creutzfeldt-Jakob disease.OBJECTIVES: During an epidemiological study of Creutzfeldt-Jakob disease in germany, Hashimoto's encephalitis was encountered as a differential diagnosis, which has not yet been described in this context. methods: The symptoms and findings of seven patients who fulfilled the criteria for "possible" Creutzfeldt-Jakob disease are presented. RESULTS: A Hashimoto's thyroiditis with antibodies against thyroglobulin or thyroid peroxidase, or both and a hypoechoic thyroid ultrasonogram were found in all cases. Analysis of CSF disclosed an increased leucocyte count in three patients, and a raised CSF:serum concentration ratio of albumin (QA1b) in four patients. The 14-3-3 protein, typical of Creutzfeldt-Jakob disease, could not be detected in any of our patients. No periodic sharp wave complexes, which are typical of Creutzfeldt-Jakob disease, were detected on EEG in any of the cases. By contrast with Creutzfeldt-Jakob disease, which leads to death within a few months, the patients with Hashimoto's encephalitis often recover quickly when treated adequately. All the patients improved after administration of corticosteroids. CONCLUSION: The clinical symptomatology of both diseases may be very similar: dementia, myoclonus, ataxia, and personality change or psychotic phenomena are characteristic symptoms.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
6/433. Maltoma of the thyroid in a man with Hashimoto's thyroiditis.We report the case of a 42-yr-old man with primary thyroid lymphoma arising from mucosa-associated lymphoid tissue (MALT-lymphoma, maltoma). The patient underwent a hemithyroidectomy for a growing mass in the right lobe of the thyroid while being treated with 1-thyroxine for Hashimoto's thyroiditis. The clinical diagnosis of Hashimoto's disease was confirmed by aspiration biopsy of the mass during the course of L-thyroxine treatment. Postoperatively, histology showed atypical lymphoproliferative infiltrates suspicious of low-grade non-Hodgkin's lymphoma of mucosa-associated lymphoid tissue-type, coexisting with a reactive process typical of chronic lymphocytic thyroiditis. immunophenotyping showed a mixed B- and T-lymphocyte population, which was nondiagnostic. However, Southern blot analysis revealed a clonal rearrangement of the Ig heavy chain gene. This case demonstrates that cytology or histology may not distinguish between reactive or low-grade lymphomatous thyroid processes. The use of molecular technique was essential to prove clonality and the presence of lymphoma.- - - - - - - - - - ranking = 6keywords = thyroiditis (Clic here for more details about this article) |
7/433. diagnosis and physiopathology of laryngeal deposits in autoimmune disease.We report the clinical features and pathology of a previously unreported form of vocal fold disease seen in 4 patients, 3 of whom were diagnosed as autoimmune disease. The characteristic features of these lesions were found as bilateral transverse lesions in the mid portion of the vocal folds. The patients had dysphonia and diplophonia. Stroboscopic examinations showed 180-degree phase shifts between the anterior and posterior portion of the vocal folds. Case 1 had systemic lupus erythematosus, case 2 had Hashimoto's thyroiditis, and case 3 had progressive systemic sclerosis. Prior to the onset of hoarseness, autoimmune antibody titers were increased. These cases need differential diagnosis from vocal fold nodules and cysts. Two cases were recurrent after endoscopic surgery, 1 recurring 3 times. Glucocorticoid was effective in preventing the recurrence in the early phase. recurrence may have occurred because the surgical strategy was the same as that used for vocal fold nodules or cysts.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
8/433. Tall cell variant of papillary carcinoma coexisting with chronic lymphocytic thyroiditis. A case report.BACKGROUND: Recent studies have shown a correlation between lymphocytic thyroiditis and papillary carcinoma of the thyroid. It is thought that autoimmune thyroiditis could be a risk factor for the development of thyroid carcinoma, mainly for the papillary variant. CASE: A 59-year-old female presented with a history of enlargement in the neck and five months of dysphagia. Clinical examination showed generalized expansion and an increase in the hardness of the thyroid gland. Hormonal outline showed subclinical hypothyroidism with serum levels of TSH slightly elevated (5 micrograms/dL; range, 0.25-4). thyroglobulin antibodies and thyroperoxidase titers were moderately positive. Given these results, a diagnosis of chronic thyroiditis was made. Thyroid ultrasound scan showed diffuse gland irregularity and the presence of a solitary nodule (2.3 cm in diameter) localized in the right lobe. Fine needle aspiration biopsy (FNAB) of the nodule was performed under ultrasound guidance. CONCLUSION: Although clinical and laboratory results supported the diagnosis of autoimmune thyroiditis only, FNAB of the nodular lesion provided evidence of a rare case of papillary carcinoma, tall cell variant, confirmed by histologic results.- - - - - - - - - - ranking = 8keywords = thyroiditis (Clic here for more details about this article) |
9/433. Transplacental passage of anti-thyroid auto-antibodies in a pregnant woman with auto-immune thyroid disease.We report the intra-uterine and postnatal thyroid status of a newborn, whose mother, affected with Hashimoto's thyroiditis superimposed on a previous Graves' disease, again became hyperthyroid during the third trimester of pregnancy. The mother had very high levels of anti-thyroid auto-antibodies, including TSH receptor auto-antibodies (TRAb) measured as TSH-binding inhibiting auto-antibodies (TBIAb). In order to exclude fetal thyroid dysfunction due to passive transplacental transfer of TRAb, fetal blood samples were obtained by cordocentesis at 21, 27 and 32 weeks of gestation. A transplacental transfer of TRAb was already seen at 21 weeks, but no alteration of fetal thyroid function was present at that time. In the following weeks, a rise in TRAb and circulating thyroid hormones was observed both in the fetus and mother, accompanied by overt hyperthyroidism in the mother and by growth retardation in the fetus. At birth, TRAb were shown to have stimulating activity both in the newborn and mother. This report documents the early transplacental passage of thyroid auto-antibodies and underlines the importance of close follow-up of pregnant women with auto-immune thyroid disorders.- - - - - - - - - - ranking = 1keywords = thyroiditis (Clic here for more details about this article) |
10/433. lupus nephritis in juvenile myelomonocytic leukemia.A 13-year-old girl developed lupus nephritis and Hashimoto thyroiditis in the chronic phase of juvenile myelomonocytic leukemia (JMML). At age 7 months, she was diagnosed as having JMML based on the hepatosplenomegaly, leukocytosis, thrombocytopenia, increased levels of fetal hemoglobin, and spontaneous in vitro growth of granulocyte-macrophage progenitors. At the onset of JMML, she had hypergammaglobulinemia, antinuclear antibodies, rheumatoid factors and anti-smooth muscle antibody. She had been placed on oral 6-mercaptopurine for about 12 years, with clinical improvement. At age 13 years, she was found to have hematuria and proteinuria. She also developed arthritis and Raynaud's phenomenon as well. She had antinuclear antibodies, rheumatoid factors, LE phenomenon, beta-1C (C3) nephritic factor (C3NeF), antithyroid antibodies, and hypocomplementemia. The renal biopsy specimens revealed a diffuse increase in the mesangial cells and matrix by light microscopy, and intense staining of IgG, Clq and C3 by immunofluorescence microscopy. The hormonal study ultimately showed decreased thyroid functions. So she was diagnosed as lupus nephritis and Hashimoto thyroiditis. The patient is the first example to show close relationship between stem cell abnormalities in JMML and development of overt autoimmune disorders.- - - - - - - - - - ranking = 2keywords = thyroiditis (Clic here for more details about this article) |
