Investigation of Helicobacter pylori in tonsillary tissue with Pronto Dry test and pathologic examination.

Objective: The objectives of this clinical study were to identify, by means of the Pronto Dry test and pathologic examination, Helicobacter pylori (HP) in tonsillary tissue and to establish the role of HP in tonsillary microbiology by identifying that bacterium in the tonsillary mucosa or within the tonsil core.

Methods: The subjects consisted of 52 patients (25 men and 27 women; age range, 3-65 years; mean age, 15.1+/-14.

Management of infracentimetric thyroid nodules with respect to ultrasonographic features.

An assumed indolent course of thyroid microcarcinomas and concerns about the cost-effectiveness of treatment raise management issues. As various studies have reported controversial results, management remains unclear. The purpose of this study was to examine the use of ultrasonography (US) in detecting malignancies in a series of 589 infracentimetric nodules.

Differences in bone turnover and intact PTH levels between African American and Caucasian patients with end-stage renal disease.

Background: Evidence derived from healthy subjects suggests that African Americans have higher serum parathyroid hormone (PTH) levels and decreased bone responsiveness to PTH than Caucasians. African American patients with end-stage renal disease (ESRD) also have higher serum PTH than Caucasians. Studies that correlate intact PTH (iPTH) levels with bone turnover in ESRD patients were performed in a predominantly Caucasian population.

Racial differences in parathyroid hormone levels in patients with secondary hyperparathyroidism.

Aim: African-Americans (AA) with normal renal function have higher parathyroid hormone (PTH) levels than Caucasians (C). This difference was also noted in cross-sectional studies of patients on dialysis. In this study, we evaluated patients with end-stage renal disease who have just began dialysis and who were not receiving any vitamin D therapy.
