AIMS Although many studies have been performed on CYP2C19, most of them have mainly examined the effects of the defective alleles CYP2C19(*)2 and CYP2C19(*)3. A comprehensive search for genetic polymorphisms of the CYP2C19 gene in the Chinese Han population has rarely been conducted. The present study was designed to determine the genetic basis of CYP2C19(More)
BACKGROUND The American Thyroid Association recently changed its management guidelines for papillary thyroid cancer (PTC) to include routine central neck lymph node dissection (CLND) during thyroidectomy. We currently perform CLND during thyroidectomy only if enlarged central nodes are detected by palpation or ultrasonography; we perform CLND in the(More)
abstract Metabotropic ␥-aminobutyric acid (GABA) receptors were studied in amphibian retinal ganglion cells using whole cell current and voltage clamp techniques. The aim was to identify the types of receptor present and their mechanisms of action and modulation. Previous results indicated that ganglion cells possess two iono-tropic GABA receptors: GABA A R(More)
HYPOTHESIS Airway complications after thyroidectomy for substernal goiter can be predicted by preoperative symptom profiles, radiologic findings, or other factors. DESIGN Retrospective review. Settings A university tertiary care center and a veterans' hospital. PATIENTS Sixty patients with substernal goiter who underwent thyroidectomy between 1993 and(More)
CONTEXT Parathyroid carcinoma is a rare but ominous cause of primary hyperparathyroidism. OBJECTIVES AND MAIN OUTCOME MEASURES: The objective of the study was to review the outcomes of parathyroid cancer patients and to evaluate the factors associated with mortality. DESIGN, SETTING, AND PATIENTS This was a retrospective review performed on 37 patients(More)
BACKGROUND Familial nonmedullary thyroid cancer (FNMTC) is associated with earlier onset and more aggressive behavior than its sporadic counterpart. Although candidate chromosomal loci have been proposed for isolated families with variants of FNMTC, the etiology of most cases is unknown. We aimed to identify loci linked to FNMTC susceptibility using(More)
In this article we review the management of benign and malignant adrenal tumors, with an emphasis on oncologic concerns. Concise, logical guidelines for the diagnosis and operative treatment of incidentalomas, aldosteronomas, adrenal Cushing syndrome, virilizing and feminizing adrenal tumors, isolated adrenal metastases, and adrenocortical carcinoma are(More)
OBJECTIVE To determine whether technetium Tc 99m sestamibi scanning is accurate enough to allow surgeons to perform unilateral neck exploration for first-time parathyroidectomy in patients with primary hyperparathyroidism. DESIGN Retrospective review. SETTING University tertiary care center. PATIENTS Forty patients with primary hyperparathyroidism who(More)
HYPOTHESIS That the clinical presentations, biochemical profiles, and surgical outcomes of patients treated with laparoscopic vs open adrenalectomy for primary hyperaldosteronism are different. DESIGN, SETTINGS, PATIENTS, AND INTERVENTIONS: The medical records of 80 patients with primary hyperaldosteronism who underwent open adrenalectomy between 1975 and(More)
BACKGROUND Approximately 30% of fine-needle aspiration (FNA) biopsies of thyroid nodules are indeterminate or nondiagnostic. Recent studies suggest microRNA (miRNA, miR) is differentially expressed in malignant tumors and may have a role in carcinogenesis, including thyroid cancer. The authors therefore tested the hypothesis that miRNA expression analysis(More)
