Background. Due to low incidence of Graves’ ophthalmopathy (GO) among children, the manifestation is poorly analyzed, posing a risk to late identification of insidious disease.Purposes. To identify predictive factors that may influence the development of GO in pediatric and young patients with Graves’ disease (GD).Methods. A cross-sectional study of patients newly diagnosed with pediatric or juvenile GD during 2002–2012 was conducted at the Hospital of Lithuanian University of Health Sciences. Ocular evaluation was based on European Group on Graves’ Orbitopathy survey. The ocular manifestations were analyzed in relation to demographic, environmental, and clinical factors.Results. In total, 130 patients with juvenile GD were included; 29.2% had GO. Median age at GD onset was 17 yrs (IQR 4–29). Main symptoms of GO were eyelids retraction (73.7%), proptosis (65.8%), injection of conjunctiva (42.1%), and eyeball motility disturbance (21.1%). Major significant and independent risk factors for GO development were high initial concentration of FT4 (OR = 5.963), TTHAb (OR = 6.358), stress (OR = 6.030), and smoking (OR = 7.098).Conclusion. The major factors that could influence GO development were smoking, stress, and increased levels of initial TRAb, FT4. Slight proptosis, retraction of eyelids, and conjunctive injection were found as predominant ophthalmological symptoms in juvenile GO.

AbstractBackgroundAlthough the most common cause of thyrotoxicosis is Graves’ disease, the determination of the cause of thyrotoxicosis is important for establishing appropriate management. Diagnosis of surreptitious ingestion of thyroid hormones or factitious thyrotoxicosis often presents a difficult challenge especially in a patient with previously diagnosed Graves’ disease. The objective of this report was to demonstrate various approaches to support the diagnosis of factitious thyrotoxicosis.Case presentationWe describe a patient with underlying Graves’ disease who underwent definitive therapy and needed long-term levothyroxine (LT4) replacement therapy. Later she developed thyrotoxicosis. Although factitious thyrotoxicosis was suspected because of very low thyroid uptake and low thyroglobulin (Tg) levels with the absence of thyroglobulin antibodies (TgAbs), she still refused any medication or substance use. After the administration of bile acid sequestrant, the thyroid hormone levels rapidly returned to normal within 1 month.ConclusionsThe diagnosis of factitious thyrotoxicosis is based upon the absence of goiter, suppressed serum Tg level, decreased radioactive iodine (RAI) uptake, and excellent response after cholestyramine treatment.

SummaryNeuroendocrine tumors with somatostatin receptor expression may be localized by 111ln-octreotide scintigraphy. This study examines those thyroid conditions where 111 ln-octreotide uptake could be observed also in the thyroid gland. 26 consecutive patients who underwent 111 ln-octreotide scintigraphy for tumor localization were additionally examined for thyroid disease by sonography and 99mTc-pertechnetate scintigraphy. 12 of these patients had no significant thyroid uptake and had an euthyroid normal-sized thyroid gland. 14 patiens with 111ln thyroid uptakes had endemic goiters, two of them with thyroid autonomy and one with Graves’ disease. Thus, 111 ln-octreotide thyroid uptake was predominantly seen in patients with endemic goiter with or without thyroid autonomy.
