Increasing primary antibiotic resistance and ethnic differences in eradication rates of Helicobacter pylori infection in New Zealand--a new look at an old enemy.

Aims: To determine the current prevalence, primary antibiotic resistance and eradication rate with standard triple therapy of Helicobacter pylori (H. pylori) infection in South Auckland, New Zealand (NZ).

Methods: Consecutive patients undergoing gastroscopy in 2012 were prospectively enrolled.

Quantifying synovitis in rheumatoid arthritis using computer-assisted manual segmentation with 3 Tesla MRI scanning.

Purpose: To investigate the reliability, validity and feasibility of a computer-assisted manual segmentation method for determining the synovial membrane volume as a surrogate measure for synovitis in patients with rheumatoid arthritis (RA).

Materials And Methods: The 3 Tesla (T) MRI scans were acquired in 22 early RA and 16 established RA patients. Synovial membrane volumes in postcontrast T1w axial images at three wrist joint regions were determined by two nonradiologist observers using a computer-assisted manual segmentation method.
