A Search for Causes of Rising Incidence of Differentiated Thyroid Cancer in Children and Adolescents after Chernobyl and Fukushima: Comparison of the Clinical Features and Their Relevance for Treatment and Prognosis.

The incidence of differentiated thyroid cancer (DTC) is steadily increasing globally. Epidemiologists usually explain this global upsurge as the result of new diagnostic modalities, screening and overdiagnosis as well as results of lifestyle changes including obesity and comorbidity. However, there is evidence that there is a real increase of DTC incidence worldwide in all age groups.

Factors affecting the approaches and complications of surgery in childhood papillary thyroid carcinomas.

Background: The aim of the study is to analyse the factors related to permanent surgical complications in children and adolescents with papillary thyroid carcinoma treated by total thyroidectomy with central and bilateral neck dissections.

Methods: Children and adolescents aged ≤18-year-old at presentation with papillary thyroid carcinoma during the years 1988-2010 underwent thyroid and lymph-node surgeries (with a median follow-up of 19.6 years) were analysed for post-surgical complications.

Morphological Changes Induced by Bipolar Radiofrequency Ablation in Thyroid Nodules - a Preclinical Investigation.

Recently, radiofrequency ablation (RFA) has been increasingly used for the treatment of thyroid nodules. However, immediate morphological changes associated with bipolar devices are poorly shown. To present the results of analysis of gross and microscopic alterations in human thyroid tissue induced by RFA delivered through the application of the original patented device.

Morphological and clinical presentation of papillary thyroid carcinoma in children and adolescents of Belarus: the influence of radiation exposure and the source of irradiation.

Objective: The aims were to analyse the features of papillary thyroid carcinoma in a large cohort of children and adolescents in Belarus and to study the influence of radiation exposure as well as the source of irradiation on the morphological and clinical presentations of tumours.

Design And Patients: The clinical and pathological features of 1086 young patients (age range=4 to 18 inclusive, followed up for ≥18years) with papillary thyroid carcinoma diagnosed during the years 1990 to 2010 were reviewed. The patients were divided into three groups: "external radiation-related", "post-Chernobyl" (internal irradiation-related) and "sporadic".

Initial presentation and late results of treatment of post-Chernobyl papillary thyroid carcinoma in children and adolescents of Belarus.

Background: The aim of this population-based study was to evaluate the clinical and pathological characteristics and outcome of papillary thyroid carcinoma (PTC) that have arisen in the Belarusian childhood population exposed to the radioactive fallout from the Chernobyl accident within a long-term period.

Patients And Methods: The long-term treatment results were investigated in 1078 children and adolescents (<19 years old) with PTC who were surgically treated during the years 1990 through 2005.

Results: Patients had high rates of metastatic PTC at presentation, with 73.

Assessing and documenting general competencies in otolaryngology resident training programs.

Objectives: The objectives of this study were to: 1) implement web-based instruments for assessing and documenting the general competencies of otolaryngology resident education, as outlined by the Accreditation Council of Graduate Medical Education (ACGME); and 2) examine the benefit and validity of this online system for measuring educational outcomes and for identifying insufficiencies in the training program as they occur.

Methods: We developed an online assessment system for a surgical postgraduate education program and examined its feasibility, usability, and validity. Evaluations of behaviors, skills, and attitudes of 26 residents were completed online by faculty, peers, and nonphysician professionals during a 3-year period.

Combined anterior-to-posterior and posterior-to-anterior approach to paranasal sinus surgery: an update.

Objectives: To develop an anatomically and functionally based approach to endoscopic intranasal ethmoidectomy; to develop such an approach using the salient features of the anterior-to-posterior (AP) and posterior-to-anterior (PA) intranasal sinus operations; to assess the safety of this form of ethmoidectomy in a patient population.

Study Design: Retrospective chart review of patients undergoing ethmoidectomy by the authors or by residents under their direct supervision.

Setting: University teaching hospital.
