OBJECTIVE To examine the indications for operation and the frequency, efficacy, and outcome of surgical therapy for thyrotoxicosis. METHODS The medical records of all patients who underwent thyroidectomy between 1990 and 1998 were reviewed. Operative indications, laboratory evaluations, extent of thyroidectomy, pathologic findings, and morbidity and mortality were determined for patients with...

BACKGROUND Thyroid nodule is a common disorder of the thyroid. Despite their benign nature, they can be associated with multiple pathologic conditions, including thyroid cancer. METHODS This cross-sectional study determined the concordance of Ultrasound (TIRADS criteria) and Fine Needle Aspiration Biopsy (FNA-BETHESDA system) in the assessment of the nontoxic thyroid nodule. A total of 180 su...

AIMS Hyperthyroidism includes several clinical and histopathological situations. Surgery is commonly indicated after failure of medical treatment. The aim of this study was to analyze the indications and complications of surgery as well as endocrine results. MATERIALS AND METHODS Patients operated on for hyperthyroidism between 2004 and 2012 were included in a retrospective study. Total thyro...

IMPORTANCE To our knowledge, the rate of change in the size of pediatric vocal fold nodules (VFNs) has not been investigated. Improved understanding of the factors that affect change in VFN size may help to better guide treatment decisions and counselling of families. OBJECTIVE To characterize the rate of change in the size of pediatric VFNs over time and to identify which factors affect incr...

The influence of the thyroarytenoid (TA) and cricothyroid (CT) muscle activation on vocal fold stiffness and eigenfrequencies was investigated in a muscularly controlled continuum model of the vocal folds. Unlike the general understanding that vocal fold fundamental frequency was determined by vocal fold tension, this study showed that vocal fold eigenfrequencies were primarily determined by vo...

AIM To describe two new ultrasound signs for thyroid nodules - "nodule in nodule" and "hypoechoic internal septae" and assess their usefulness in differentiating follicular variant of papillary thyroid carcinoma (FVPTC) from benign thyroid nodules (BTN). METHODOLOGY Ultrasound findings of 210 patients with histopathologically proven FVPTC (68 nodules, M:F=13:47 with mean age of 39.5±11.9 year...

Nodule formation on ITO sputtering targets was investigated by stop action in-situ video observation, 3D-SIMS, and EPMA. Major cause of nodule formation is particulates from the sputtering system, less important are particulate inclusions in the target material. A nodule growth mechanism and strategies to minimize nodule formation are proposed.

We present two cases of solitary necrotic nodules of the liver which on radiologic images mimicked hepatic metastasis. Solitary necrotic nodule of the liver is a rare but benign entity which histopathologically consists of an outer fibrotic capsule with inflammatory cells and a central core of amorphous necrotic material. The lesion was seen on contrast-enhanced CT as an ovoid-shaped hypoattenu...

the main purpose of this semi - experimental study was to examine the effects of rehearsal strategies training on second language vocabulary learning . in particular , four training methods were examined : ( a ) vocal rehearsal , ( b ) subvocal rehearsal , ( c ) vocal and subvocal rehearsal, and ( d ) no rehearsal . one hundred and sixty - two undergraduate freshmen ( four intact classes from f...
