Graves' ophthalmopathy (GO) is characterized by expanded volume of the orbital tissues associated with elevated serum levels TSH receptor (TSHR) autoantibodies. Because previous studies have demonstrated evidence adipogenesis within GO orbit, we sought to determine whether M22, a human monoclonal antibody directed against TSHR, enhances in fibroblasts from patients and, if so, identify signaling mechanisms involved. fibroblast cultures (n=10) were treated for 10 days bovine (1 or 10.0 U/l)...

Surgically managed endocrinopathies are rare in children. Most surgeons have limited experience this field. Herein we report our operative with pediatric patients, performed over two decades by high-volume endocrine surgeons.The study was conducted at the Mayo Clinic (a tertiary referral center).Patients were <19 years old and underwent an operation (1993-2012).Demographics, surgical procedure, diagnoses, morbidity, mortality retrospectively reviewed.A total of 241 primary cases included 177...

Graves ophthalmopathy (GO) is an autoimmune disorder characterized by increased adipogenesis and hyaluronan (HA) production orbital fibroblasts. Circulating autoantibodies (thyroid-stimulating antibodies [TSAbs]) directed at the thyrotropin receptor (TSHR) on these cells stimulate or augment cellular processes. A recently developed drug-like small molecule inverse agonist of TSHR, NCGC00229600, termed 1, binds to TSHR blocks basal stimulated signal transduction.The purpose this article was...

Graves' ophthalmopathy (GO) is characterized by expanded volume of the orbital fat and extraocular muscle tissues elevated levels TSH receptor autoantibodies (TRAb). The expansion involves accumulation hyaluronic acid (HA) within orbit.The objective study was to determine whether a monoclonal stimulatory TRAb (M22) impacts HA synthesis in GO cells and, if so, this might be blocked an IGF-I (IGF-IR)-blocking antibody (1H7) or inhibitors various downstream signaling cascades.GO fibroblast...

In adults without thyroid disease, increasing levels of thyroid-stimulating hormone (TSH) within the range that considered normal have been shown to be associated with increases in total cholesterol, low-density lipoprotein non-high-density and triglycerides, decreases high-density cholesterol. Serum TSH has also found positively fasting postload insulin concentrations negatively sensitivity euthyroid adults. We hypothesized such relationships exist children adolescents.This was a...

Methods Adolescents (ages 12–18 years) obesity (BMI ≥1.2 times 95th percentile or BMI ≥35 kg/m 2 ) were recruited this double‐blind, randomized, placebo‐controlled trial. Participants completed 4 weeks randomization (1:1) to either 24 75 mg/day placebo. Mean changes compared between groups. Results Thirty (mean age...

Intra-articular and intradermal steroids are often used for their antiinflammatory effect. There is limited experience with intra-articular intralesional administration of corticosteroids in the pediatric age group.We performed a retrospective chart review 3 patients who developed Cushing's syndrome after local triamcinolone acetonide (TCA).Two females 9 17 years old, received injections TCA. One patient multiple TCA into interphalangeal joints (cumulative dose: 120 mg), whereas other single...

Background: Patients with Graves' ophthalmopathy (GO) have circulating autoantibodies directed against the thyrotropin receptor (TSHR) and elevated levels of proinflammatory cytokine interleukin-6 (IL-6) in both serum orbital tissues. We hypothesized that these might increase IL-6 expression secretion preadipocyte fibroblasts adipocytes from patients GO, thus directly impact clinical activity disease. Methods:IL-6 mRNA were measured cultures GO preadipocytes (n = 3) treated during adipocyte...
