Direct development is a widespread, alternative life history in Recent amphibians. There is no free-living, aquatic larva; adult features form in the embryo and are present at hatching. The mechanistic bases of direct development remain relatively unexplored. The current study describes the embryonic ontogeny of the thyroid gland in the direct-developing frog Eleutherodactylus coqui (Leptodacty...

Introduction: Postpartum thyroiditis (PPT) is an autoimmune disease associated with the presence of thyroid autoantibodies (TAAb) and changes in the morphological characteristics of the thyroid gland. Aim: To investigate the clinical importance of certain immunological and ultrasound thyroid characteristics for the diagnosis of postpartum thyroiditis. Patients and methods: 33 women with PPT and...

OBJECTIVE To prospectively evaluate the heterogeneous appearance of the thyroid gland, reflecting inflammation and destruction in euthyroid Hashimoto's thyroiditis (HT), we investigated the clinical utilities of the heterogeneity index (HI) [the coefficient of variance (CV) of the ultrasonographic (US) intensities], focusing on anti-thyroid peroxidase antibodies (TPO-Ab), which represent not on...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

The study presents an experimental model of alcoholism. Female and male rats of Wistar albino were given 15% ethanol as the only drinking solution daily one month before mating, and the said amount was further administered to the females during both pregnancy and lactation. Control rats (n=22) received tap water. It was generally accepted that long-term administration of ethanol affected the th...

Although several reports have defined normal thyroid volume depending on either age or body surface, there are no sequential reference values on childhood thyroid volume evaluated by using ultrasonography and epidemiological analysis in Japan. The aim of the present study was to establish updated reference values for thyroid volume by ultrasound examination and epidemiological analysis in 0-19 ...

Swelling of the thyroid gland is a common symptom in patients with Graves' disease. However, until recently there were no adequate means of measuring the thyroid volume. In this study, thyroid volume (in Graves' disease patients on antithyroid drug (ATD) therapy) was measured serially by a new ultrasound technique involving the use of a specifically programmed computer. The relationships betwee...

background: the therapeutic administration of 131i for thyroid remnant ablation and for metastases comes up with some adverse effects. this study was conducted to investigate whether single high dose radioiodine therapy affects lacrimal gland functions or not. materials and methods: seventy-eight eyes of 39 patients, who were diagnosed as differentiated thyroid carcinoma, were objectively teste...

BACKGROUND Levothyroxine (L-T4) treatment of euthyroid children with Hashimoto thyroiditis (HT) is a controversial issue. PATIENTS AND METHODS We conducted a prospective, randomized, controlled clinical trial. Out of 79 identified euthyroid patients, 59 started the study; 25 patients (21 female, 4 male; age: 11.8 ± 2.3 years) received L-T4 at a mean dose of 1.6 µg/kg (SD, 0.8) daily, and 34 (...
