Combining the American Thyroid Association's Ultrasound Classification with Cytological Subcategorization Improves the Assessment of Malignancy Risk in Indeterminate Thyroid Nodules.

The risk of malignancy (RoM) of indeterminate thyroid nodules (ITNs) shows a high variability in interinstitutional cohorts. The RoM is partially associated with the cytological degree of atypia and the ultrasound (US) pattern. This study evaluated the cancer risk of ITNs by jointly considering the cytological subcategory and the American Thyroid Association (ATA)-based US risk classification.

Teaching with research: a strategy for students of postgraduation in medicine.

Objective: Promoting a scientific activity of research to students of a graduation program as a reflexive tool of teacher and formative practice of necessary activities to construction of a research in medical education.

Methods: Graduation students of surgery at UFRJ did a research, randomly interviewing a population of medical teachers who acts at Medicine Universities of Rio de Janeiro. The study was structured in three steps: definition of the investigative content; realization of 150 interviews before field research and discussion about the results.

Parathyroid carcinoma and oxyphil parathyroid adenoma: an uncommon case of misinterpretation in clinical practice.

A 46 year-old male presented with persistently high level of serum parathyroid hormone (PTH), despite successful resection of an oxyphilic cell parathyroid adenoma of the left lower gland. Renal function and serum calcium were normal, leading to vitamin D deficiency being considered. Tc99m-sestamibi parathyroid scintigraphy showed no capitation, but a cervical ultrasound demonstrated an increase in the lower parathyroids.

Ectopic and extranumerary parathyroid glands location in patients with hyperparathyroidism secondary to end stage renal disease.

Unlabelled: Supranumerary or ectopic parathyroid glands are the main cause of persistent hyperparathyroidism (HPT) in patients with end stage renal disease (ESRD) submitted to parathyroidectomy (PTx).

Purpose: To evaluate the prevalence and location of parathyroid glands in these patients.

Methods: Thirty-five patients with ESRD and severe secondary hyperparathyroidism (HPT2) had been submitted to total PTx at HUCFF from December 2001 to July 2005.
