Background: Radiation exposure is a well-known risk factor for well-differentiated thyroid cancer (WDTC). However, disease characteristics, optimal treatment, time from exposure to disease appearance, and the effect of age at initial exposure on the outcome have yet to be determined.
Objectives: To identify the characteristics of radiation-induced thyroid carcinoma.
Context: Prognostic factors for pediatric differentiated thyroid cancer (DTC) are not well established.
Objective: The objective of the study was to retrospectively compare the postoperative risk-stratification systems: American Thyroid Association (ATA) risk categories, Schneider Children's Medical Center of Israel (SCMCI) score, and the response to initial therapy as predictors for disease outcome.
Patients And Methods: Fifty-four DTC patients, median age at diagnosis 13.
Background: Sonographic size of suspicious thyroid lesions is an essential parameter in the evaluation of thyroid nodules, determining the need for needle biopsy and has impact on the extent of surgery. Limited data is available on the correlation between the size of the thyroid nodule on sonography and the actual size measured during histological examination. The aim of the present study was to compare these two modalities and to discuss the potential clinical implications of the findings in the study population.
View Article and Find Full Text PDFBackground: Indications for thyroidectomy during laryngectomy are controversial. We examined whether clinicopathologic features can predict thyroid gland involvement, and the prognostic effect of thyroid gland involvement in patients undergoing total laryngectomy.
Methods: The study set out to review preoperative assessment, operation findings, pathologic findings, and follow-up data.
Purpose: The natural history of papillary thyroid carcinoma (PTC) is characterized by a slow growth rate and an excellent prognosis at 20 and 30 years. However, there is a small subset of patients with poorer outcome.
Methods: Twenty patients who died of PTC within 10 years of diagnosis were studied to identify prognostic indicators and biological markers of early death.

Objectives: We sought to investigate the immunologic status of children with recurrent respiratory papillomatosis and to evaluate possible correlations between the patients' immunocompetency and the clinical course of the disease.
Methods: Twenty children with recurrent respiratory papillomatosis underwent immunologic evaluation every 6 months for determination of complete blood count, serum immunoglobulin levels, lymphocyte subpopulations, lymphocyte response to mitogen stimulation, and natural killer cell function. The patients were observed prospectively (42 to 56 months), and their clinical course was recorded.

Objective: To determine the safety and effectiveness of endoscopic partial adenoidectomy for the treatment of nasal obstruction in children with submucosal cleft palate.
Methods: The medical files of children with symptoms of nasal obstruction and submucosal cleft palate who underwent partial transnasal endoscopic adenoidectomy from January 1993 to December 2003 were reviewed. Operative complications, relief of nasal obstruction, presence of postoperative velopharyngeal insufficiency were recorded.

Objective: Well-differentiated thyroid carcinoma is considered an indolent malignant disease. Although rare, extrathyroidal invasion is associated with a worse prognosis and increased risk of morbidity. Management remains controversial, with some authors advocating conservative treatment with preservation of midline structures and others, aggressive extensive en bloc resection.
View Article and Find Full Text PDFPurpose: Solitary adenoma of the parathyroid is the major cause of primary hyperparathyroidism. Many centers advocate a minimally invasive surgical approach, wherein the surgeon explores only a localized area of the neck according to the preoperative imaging evaluation, and the adenoma is resected without histological sampling from the other parathyroid glands. The aim of this study was to evaluate the ability of high-resolution ultrasonography (US) to localize adenomas preoperatively and thereby aid in patient selection for minimal procedures.

This study demonstrates the value of sentinel node biopsy for head and neck melanoma, and highlights the associated difficulties. Thirty consecutive patients with primary cutaneous melanoma of the head and neck (n=26) or draining to the neck (n=4) underwent preoperative lymphoscintigraphy.
View Article and Find Full Text PDFThe distinction of uncommon types of thyroid carcinomas is important, because their treatment and prognosis differ. The aim of this study was to describe retrospectively the immunohistochemical profile of uncommon types of thyroid carcinomas and mode of treatment. Of the 1194 patients with thyroid carcinomas treated in Rabin Medical Center from 1954 to 2001, 153 were uncommon types (not papillary or follicular carcinomas).
View Article and Find Full Text PDFBackground: The main limitation of fine-needle aspiration (FNA) is its limited distinction between neoplastic and benign lesions. We summarize our experience with thyroid nodules that were defined as follicular lesions by comparing the clinical and cytological features of the thyroid follicular lesions that were examined histologically to define the most reliable criteria of malignancy.
Methods: The medical records of all patients who underwent thyroid aspiration at Rabin Medical Center from 1999 to 2000 were reviewed for a diagnosis of follicular lesion that warranted surgery (N = 58).
