The results of our study suggest that people with the Ala12 allele of the PPAR-gamma2 gene could be more sensitive to insulin than those carriers of the Pro12 allele among Brazilian Caucasians.
The present study demonstrated increased truncal and leg fat among women with PCOS. The study did not detect any difference in insulin parameters but larger studies could be more suitably powered to investigate this. CLINICALTRIALS.GOV: NCT02467751.
We carried out a retrospective study of 20 cases of thyroid carcinoma followed at the Pediatric Endocrinology Unit of Santa Casa de São Paulo between 1982 and 2002. Asymptomatic thyroid nodules were the most frequent clinical presentation. Adenomegaly was present in 50% of the cases at the time of diagnosis. Female patients were more affected than males at a proportion of 3:1. Scintigraphy showed a predominance of cold nodules, and ultrasonography showed the presence of solid nodules and/or solid with cystic components. Fine needle aspiration biopsy was done in 12 cases and was positive in 6 (50%), and in 4 cases, the cytology results were suspicious. The treatment of choice was total thyroidectomy with lymphadenectomy, followed by whole-body scan and ablative radioiodine therapy. Postoperative treatment sought to maintain suppressed levels of thyroid-stimulating hormone and serum thyroglobulin. Although children and adolescents with thyroid carcinoma have a better prognosis than adults, we found that metastasis at the time of diagnosis is more frequent in children than in adults.Key Words: thyroid carcinoma, radioiodine, head and neck nodule, children thyroid disease, thyroid fine needle aspiration biopsy (The Endocrinologist 2005;15: 106 -110)
Learning Objectives• List the demographic features of children and adolescents who have thyroid carcinoma and identified risk factors.• Summarize the presenting clinical features of thyroid cancer in this age group and the laboratory and imaging procedures used to confirm the diagnosis. • Recall the treatment options for preadult patients with thyroid cancer and their outcome compared with that of adults with the same condition.
Objectives: We sought to assess the relationship between stimulated thyroglobulin (sTg) before radioactive iodine therapy (RIT), and the dynamic risk stratification 1 year after treatment, and to establish the utility of the sTg as a predictor of response to therapy in these patients. A retrospective chart review of patients with differentiated thyroid cancer (DTC) who underwent RIT after surgery and were followed for at least 1 year, was carried out. Subjects and methods: Patients were classified according to the dynamic risk stratification 1 year after initial treatment. The sTg values before RIT were compared among the groups. ROC curve analysis was performed. Results: Fifty-six patients were enrolled (mean age 44.7 ± 14.4 years, 80.7% had papillary carcinoma). Patients with excellent response had sTg = 2.1 ± 3.3 ng/mL, those with indeterminate response had sTg = 8.2 ± 9.2 ng/mL and those with incomplete response had sTg = 22.4 ± 28.3 ng/mL before RIT (p = 0.01). There was a difference in sTg between excellent and incomplete response groups (p = 0.009) while no difference was found between indeterminate and either excellent or incomplete groups. The ROC curve showed an area under the curve of 0.779 assuming a sTg value of 3.75 ng/mL. Conclusion: Our study results suggest that the higher the sTg before RIT, the greater the likelihood of an incomplete response to initial treatment. A sTg cut-off of 3.75 ng/mL was found to be a good predictor of response to initial treatment in patients with DTC. Arch Endocrinol Metab. 2017;61(6):590-9
Tissues involved in GO exhibited different mRNA levels of and. Gene expression in OF was similar for TED patients and controls. , and mRNA levels were higher in TED EOM than those in control EOM. was disproportionally elevated compared with; this finding was indicative of a local proinflammatory profile.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
