OBJECTIVE Although non-toxic diffuse goitre is a common disorder, little is known of the clinical course of patients. We therefore decided to investigate the long-term clinical outcome of patients with non-toxic diffuse goitre. DESIGN A retrospective study. PATIENTS Of 850 patients with non-toxic diffuse goitre who met our criteria and were seen in our thyroid clinic between 1977 and 1985, 108 who had been followed for from 5 to 14 years (mean 8 years) were entered in this study. All patients fulfilled our criteria having soft diffuse goitres, normal serum TSH and T4 concentrations, and undetectable antithyroglobulin and antithyroid microsomal antibodies. MEASUREMENTS A family history of thyroid disease was obtained and the occurrence of Graves' ophthalmopathy was noted. Serum TSH and T4 concentrations, and antithyroglobulin and antithyroid microsomal antibodies were measured during the follow-up period. Thyroidal radioactive iodine uptake (RAIU), serum free T4 and free T3 concentrations, and TSH binding inhibitory immunoglobulin (TBII) activities were determined in all patients who were subsequently found to have abnormal serum TSH or T4 concentrations or signs of Graves' ophthalmopathy. RESULTS Thirty-six of the 108 patients (33%) had a family history of autoimmune thyroid disease. Elevated serum T4 or free T4 concentrations and depressed serum TSH concentrations were found in six patients during the follow-up period. Hyperthyroid Graves' disease was diagnosed in four of the six patients, subacute thyroiditis in one, and transient post-partum thyrotoxicosis in one. Hypothyroidism was found in one patient who was diagnosed as having transient post-partum hypothyroidism. Euthyroid Graves' disease was diagnosed in one patient. Furthermore, six of these eight patients had a family history of autoimmune thyroid disease in first-degree relatives. CONCLUSION During a prolonged follow-up period of patients with non-toxic diffuse goitre, Graves' disease was found in five of 108 patients (four hyperthyroid Graves' and one euthyroid Graves'), post-partum thyroid dysfunction in two, and subacute thyroiditis in one. Six of these eight patients had a family history of autoimmune thyroid disease in first-degree relatives. Long-term follow-up is necessary for patients with non-toxic diffuse goitre, especially those who have a family history of autoimmune thyroid disease. 相似文献

A one-mg oral overnight dexamethasone suppression test (DST) was conducted on 22 inpatients with eating disorders. To confirm that the dexamethasone tablets had been ingested, we measured the plasma concentrations of dexamethasone the next morning (at 0900 hr after DST). The diagnosis of anorexia nervosa and bulimia was made according to the criteria for DSM-III, respectively. Of the 22 patients with eating disorders, 16 satisfied the criteria for anorexia nervosa and 6 for bulimia. The DST was carried out within 2 weeks of hospitalization on each patient. The subjects were given 1 mg of dexamethasone in the evening (at 2300 hr) and blood samples were collected the following day (at 0900, 1600 and 2100 hr, respectively). The plasma cortisol and dexamethasone levels were concurrently determined by RIA. The criterion for non-suppression was a failure to suppress the plasma cortisol levels below 5.0 micrograms/dl in any one of the three samples. All but one patient with bulimia had ingested the dexamethasone. Thirteen (62%) of 21 patients with eating disorders were nonsuppressors. We found a significant positive correlation between the plasma cortisol levels at 1600 hr or 2100 hr and a decrease in ideal body weight (n = 16, r = 0.613, p less than 0.05; r = 0.75, p less than 0.01, respectively) and a significant inverse relationship between the plasma dexamethasone levels at 0900 hr and the plasma cortisol levels at 1600 hr was recognized (n = 21, r = 0.631, p less than 0.01). These results suggest that the blood dexamethasone levels as well as body weight might contribute to the abnormalities of DST seen in patients with eating disorders. 相似文献

OBJECTIVE TSH-binding inhibitory immunoglobulin (TBII) is undetectable in about 10% of untreated Graves' disease patients, but the clinical characteristics and immunological significance of this finding are unknown. In this study we evaluated the clinical characteristics of TBII negative Graves' disease. PATIENTS We examined TBII in 1048 untreated patients at Kuma hospital from 1986 to 1990 and found 69 TBII undetectable patients (12 men and 57 women, mean age ± SEM 35 ± 2 years, group A). MEASUREMENTS We compared the clinical characteristics and immunological findings of group A with 57 untreated TBII detectable Graves' patients who were selected randomly (11 men and 46 women, mean age ±SEM 40 ±2 years, group B). T4, TSH, FT4, FT3, 1231 thyroid uptake, TBII, thyroid stimulating antibodies (TSAb) and the volume of the thyroid using ultrasonography were measured at the first visit. RESULTS Serum T4, FT4 and FT3 levels in group A were significantly lower than those in group B (P<0 001). The values of TSAb in group A were significantly lower than those in group B (593±67 (mean±SE) vs 2143±280%, respectively, P < 0001). The 1231 thyroid uptake in group A was significantly lower than that in group B (53 1 ±11 vs 61 -4±14%, respectively, P<0.01).The thyroid volume in group A was significantly smaller than that in group B (391 ±3 0 vs 51 3±3 3 ml, respectively, P<0 01). TSAb was undetectable in about 10% (6) of the TBII negative untreated Graves' patients at their first visit. CONCLUSION In the present study, untreated TBII negative patients with Graves' disease were characterized by mild elevation of thyroid hormones, mildly elevated 123l uptake, weak TSAb activities and small goitres. The finding of both TBII and TSAb negative titres in untreated Graves' disease patients was also confirmed. 相似文献

Balb/c and C57BL/6 mice have been reported to be biased towards Th2 and Th1 immune responses, respectively. We investigated which strain is more susceptible to the development of experimental immune-mediated blepharoconjunctivitis (EC), which is predominantly mediated by Th2 immune responses. EC was induced by three different methods in Balb/c and C57BL/6 mice using ragweed (RW) as the antigen. The mice were thus either actively immunized with RW, passively immunized by transfer of RW-primed T cells, or passively immunized by transfer of RW-specific IgE, followed by RW challenge in eye drops. Twenty-four hours after the challenge, conjunctivas, sera and spleens were harvested for histological analysis, measurement of serum IgE and assessment of cellular immune responses, respectively. The responses of the Balb/c and C57BL/6 mice were compared. In addition, to assess the involvement of IFN-gamma in the development of EC in the two strains, IFN-gamma knockout (GKO) mice of the two strains were actively immunized and evaluated as above. Regardless of the method of induction, EC, as determined by the degree of eosinophil infiltration into the conjunctiva, was more severe in Balb/c mice than in C57BL/6 mice. Moreover, more IgE was produced by actively immunized Balb/c mice than C57BL/6 mice and RW-primed splenocytes from Balb/c mice produced more IL-4 but less IFN-gamma than those from C57BL/6 mice. EC could be induced in the GKO mice of both strains. However, when their EC was compared to that in WT mice, significantly less infiltration of eosinophils was noted in the Balb/c GKO mice. Taken together, Balb/c mice are more susceptible to EC than C57BL/6 mice and this higher susceptibility might be related to the Th2 immune response bias of Balb/c mice. Furthermore, the involvement of endogenous IFN-gamma in the development of EC in these two strains differs. 相似文献

The purpose of this study was to evaluate sonographic examination, as well as other clinical tests, for clarifying the parameters
for predicting follicular carcinoma in follicular nodules of the thyroid. Nine hundred and ten consecutive patients with follicular
nodules were pathologically classified as having follicular carcinoma (109 patients) or benign tumor (811 patients). Benign
tumors included follicular adenoma (237 patients) and adenomatous thyroid nodules (574 patients). A case-control study was
performed for follicular carcinomas and benign tumors. “Thyroglobulin 1000 ng/ml≦”, “cytology class 3≦”, and a “solid pattern”,
“low-echoic level of internal echo”, and “jagged borders” of follicular carcinomas were found to be significantly higher than
those of benign tumors. The sensitivities of a solid pattern (79.8%) and a low-echoic level (75.2%) were found to be relatively
higher than those of other features and findings. The specificities of thyroglobulin 1000 ng/ml≦(84.0%), cytology class 3≦,
and jagged borders (86.2%) were found to be relatively higher than those of other features and findings. We concluded that
thyroglobulin 1000 ng/ml≦ and cytology class 3≦ in clinical features, and a solid pattern, low-echoic level, and jagged borders
on sonography, indicated an increased risk of follicular carcinoma of the thyroid in follicular nodules. 相似文献

We determined the population genetic structures of feline and canine Staphylococcus aureus strains in Japan by multilocus sequence typing (MLST). Ecological analyses suggested that multiple feline-related S. aureus clones, including ST133, naturally occur as commensals and can cause endogenous infections in felines. In contrast, S. aureus populations do not likely include any clone that exhibits tropism in domestic dogs. Even if S. aureus infections occur in dogs, the pathologies are likely exogenous infections. 相似文献
