Systemic lupus erythematosus (SLE) is a multiorgan-involved autoimmune disease, and it can overlap organ-specific autoimmune diseases such as autoimmune thyroid diseases, autoimmune hepatitis and inflammatory bowel disease. There may be some association between SLE and these autoimmune diseases, such as common immunological and genetic basis, but the pathogenic mechanism is still unclear. This review focuses on current knowledge regarding the prevalence and possible pathogenesis of SLE overlapping the above three autoimmune diseases.

We have reviewed 1066 thyroid lesions and compared the relative incidence of the so called 'palpation thyroiditis' between autoimmune thyroiditis and normal thyroid parenchyme surrounding the nodular thyroid lesion and also discussed the pathogenesis of palpation thyroiditis. The typical histopathologic features of 'palpation thyroiditis' were seen in 275 cases among 467 adenomatous goiters and in none of the autoimmune thyroiditis. We here in this paper suggest that the so called 'palpation thyroiditis' is not merely a secondary phenomenon to mechanical follicular damage by vigorous palpation, but this lesion more likely develops in conditions where certain types of physiologic alteration has occurred in follicular basement membrane, just like a pathogenesis of subacute granulomatous thyroiditis.

OBJECTIVETo analyze factors relevant to retarded intellectual development in infants born to mothers with autoimmune disease of thyroid.

METHODSAll the term newborns born to mothers with autoimmune thyroid disease (selection criteria) without asphyxia in all county, city, and provincial hospitals in Zhejiang province (except for Ningbo City) from July 2001 to June 2003 were enrolled through Zhejiang provincial neonatal disease screening network system. The control group was consisted of the neonates who were born to mothers without thyroid disease in these hospitals during the same period. Heel capillary blood samples were collected from the neonates older than 3 days in local hospitals and sent to the center of Zhejiang provincial neonatal disease screening network system. TSH levels were measured by Time Difference Fluorescent Analysis Device (1420 II type, EGG Company, US). If the level of TSH was higher than 9 mU/L, their mothers were called back to the center with their infants within 3 days. If the level of TSH was normal, they were called back to hospitals at age of 28 - 35 days of infants. The pattern of maternal thyroid disease, duration, thyroid function, the history of maternal drug administration, maternal age, gestational age and body weight of the neonates were recorded. The neonatal and maternal serum thyroid function tests were re-performed and the serum TPOAb, TGAb, TRAb and TSAb levels in both neonates and their mothers were measured as well. A 1-year follow-up study was done and all these subjects were investigated by means of Gesell development schedules by special investigators at the age of 1, 3, 6 and 12 months. The results were expressed as developmental quotient. Case-sectional study was performed. Statistical analyses were conducted using SPSS software. The multiple logistic regression analysis was used to analyze factors which might have effect on infantile personal-social ability, adaptive ability, gross motor ability or the fine-motor ability. One-way ANOVA was used to compare those five subfields ability followed by LSD multiple comparisons and Dunnet's C test was used when variances were not equal. Correlation analysis was used to compare the anti-thyroid antibody between neonates and their mothers.

RESULTSPoor personal-social ability, adaptive ability, gross motor ability and fine motor ability of infants born to mothers with autoimmune thyroid diseases were found as compared to the infants born to healthy mothers (P < 0.01). Moreover, the infants born to mothers with Hashimoto's thyroiditis had significantly poorer fine motor ability and adaptive ability than those born to mothers with Grave's disease (P < 0.05). The Spearman correlation coefficients of TPOAb, TGAb, TRAb and TSAb were 0.636, 0.574, 0.619 and 0.473, respectively, and all the P values were lower than 0.01.The multifactor logistic regression analysis showed that infantile TPOAb levels and maternal TRAb levels were associated with infantile personal-social ability, adaptive ability, and gross motor; while maternal TPOAb levels and thyroid function during gestation were associated with infantile fine-motor ability (P < 0.05).

CONCLUSIONMaternal autoimmune thyroid diseases during pregnancy had adverse effects on intellectual development of infants. The maternal levels of TPOAb, TRAb and thyroid status were associated with the infantile personal-social ability, adaptive ability, gross motor and fine motor development. In order to reduce the effect on infant, it is necessary to treat adequately the maternal autoimmune thyroid diseases during pregnancy.

Lifelong thyroid hormone replacement is indicated in patients with hypothyroidism as a result of Hashimoto's thyroiditis. However, previous reports have shown that excess iodine induces hypothyroidism in Hashimoto's thyroiditis. This study investigated the effects of iodine restriction on the thyroid function and the predictable factors for recovery in patients with hypothyroidism due to Hashimoto's thyroiditis. The subject group consisted of 45 patients who had initially been diagnosed with hypothyroidism due to Hashimoto's thyroiditis. The subjects were divided randomly into two groups. One group was an iodine intake restriction group (group 1) (iodine intake: less than 100 microgram/day) and the other group was an iodine intake non-restriction group (group 2). The thyroid-related hormones and the urinary excretion of iodine were measured at the baseline state and after 3 months. After 3 months, a recovery to the euthyroid state was found in 78.3 % of group 1 (18 out of 23 patients), which is higher than the 45.5% from group 2 (10 out of 22 patients). In group 1, mean serum fT4 level (0.80 +/- 0.27 ng/dL at the baseline, 0.98 +/- 0.21 ng/dL after 3 months) and the TSH level (37.95 +/- 81.76 microIU/mL at the baseline, 25.66 +/- 70.79 microIU/mL after 3 months) changed significantly during this period (p < 0.05). In group 2, the mean serum fT4 level decreased (0.98 +/- 0.17 ng/dL at baseline, 0.92 +/- 0.28 ng/dL after 3 months, p < 0.05). In the iodine restriction group, the urinary iodine excretion values were higher in the recovered patients than in non-recovered patients (3.51 +/- 1.62 mg/L vs. 1.21 +/- 0.39 mg/ L, p=0.006) and the initial serum TSH values were lower in the recovered patients than in the non-recovered patients (14.28 +/- 12.63 microIU/mL vs. 123.14 +/- 156.51 microIU/mL, p=0.005). In conclusion, 78.3% of patients with hypothyroidism due to Hashimoto's thyroiditis regained an euthyroid state iodine restriction alone. Both a low initial serum TSH and a high initial urinary iodine concentration can be predictable factors for a recovery from hypothyroidism due to Hashimoto's thyroiditis after restricting their iodine intake.

Eosinophilic fasciitis (EF) is scleroderma-like disease without Raynaud's phenomenon or visceral involvement. It is characterized by painful swelling of the extremities, accompanied by rapid weight gain, fever and myalgia. The acute state of disease is associated with significant peripheral blood eosinophilia, an elevated erythrocyte sedimentation rate and hypergammaglobulinemia. EF is also frequently associated with hematological abnormalities, including malignant lymphoproliferative diseases, but rarely associated with autoimmune thyroiditis. In the present study we report a case of eosinophilic fasciitis associated with autoimmune thyroiditis.

PURPOSE: Acute kidney injury (AKI) caused by hypothyroidism-induced rhabdomyolysis is a rare and potentially life-threatening syndrome. The aim of this study was to investigate the clinical characteristics of such patients. MATERIALS AND METHODS: We retrospectively analyzed five patients treated at the Second Affiliated Hospital of Chongqing Medical University with AKI secondary to hypothyroidism-induced rhabdomyolysis from January 2006 to December 2010. RESULTS: Of the five cases reviewed (4 males, age range of 37 to 62 years), adult primary hypothyroidism was caused by amiodarone (1 case), chronic autoimmune thyroiditis (1 case), and by uncertain etiologies (3 cases). All patients presented with facial and lower extremity edema. Three patients presented with weakness, while two presented with blunted facies and oliguria. Only one patient reported experiencing myalgia and proximal muscle weakness, in addition to fatigue and chills. Creatine kinase, lactate dehydrogenase, and renal function normalized after thyroid hormone replacement, except in two patients who improved through blood purification. CONCLUSION: Hypothyroidism should be considered in patients presenting with renal impairment associated with rhabdomyolysis. Moreover, further investigation into the etiology of the hypothyroidism is warranted.

The primary esophageal lymphoma is extremely rare, and shows various morphologic characteristics. Only a single case of mucosa-associated lymphoid tissue (MALT) type lymphoma confined to the esophagus has been reported in the literature. A 61-yr-old man was referred to our hospital for evaluation of an esophageal submucosal tumor (SMT) that had been detected incidentally by endoscopy. He had a history of pulmonary tuberculosis with long-term anti-tuberculosis medication 15 yr before, and also had a history of syphilis, which had been treated one year before. He had been taking a synthetic thyroid hormones for the past 10 months because of an autoimmune thyroiditis. Endoscopy showed a longitudinal round and tubular shaped smooth elevated lesion, which was covered with intact mucosa and located at the mid to distal esophagus, 31 cm to 39 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a huge longitudinal growing intermediate- to hypo-echoic mass located in the submucosal layer with internal small, various sized honeycomb-like anechoic lesions suggesting germinal centers. Subsequently, he underwent a surgery, which confirmed the mass as a primary esophageal low-grade B-cell lymphoma of MALT type.

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) is a recently recognized malignant neoplasm of the thyroid gland. About 14 cases of SMECE have been reported and this is the first reported case in Korea. A 57-year-old woman presented with right neck mass for 20 years. Total thyroidectomy was performed under the impression of thyroid carcinoma. The resected thyroid gland showed a poorly circumscribed hard mass. Histologically, the tumor consisted of solid nests of large atypical cells with dense fibrous stroma. The tumor cells showed squamoid appearance with abundant eosinophilic cytoplasm. There were also rare mucin-containing cells within the nests. Within the hyalinized stroma, numerous eosinophils were found. The surrounding thyroid parenchyma displayed Hashimoto's thyroiditis. There was metastasis in a regional lymph node. Two years after initial surgery, she underwent a modified radical neck dissection due to recurrent neck mass. After the radiation therapy for eight weeks, laryngectomy and esophagectomy were performed due to a recurrent carcinoma in the esophageal wall. We report an additional case of SMECE, with metastasis to regional lymph nodes and esophagus. The tumor appears to be more aggressive than previously reported and a correct diagnosis can be rendered by just examining the metastatic lesions.
