Hoffman, P S, Goodwin, A, Johnsen, J, Magee, K, Veldhuyzen Van Zanten, S J
In this study, we compared metronidazole (Mtz)-sensitive and -resistant strains of Helicobacter pylori for metabolic differences that might correlate with drug resistance. Included in this study was...
Serological detection of Helicobacter pylori antibodies in children and their parents.
Best, L M, Veldhuyzen Van Zanten, S J, Sherman, P M, Bezanson, G S
The antibody response to Helicobacter pylori was examined in 56 children (ages 5 to 18) to determine whether serological tests can be used for diagnosis. Twenty-four children (43%) were H. pylori...
Serological detection of Helicobacter pylori by a flow microsphere immunofluorescence assay.
Best, L M, Veldhuyzen Van Zanten, S J, Bezanson, G S, Haldane, D J, Malatjalian, D A
A flow cytometric immunofluorescence assay (FMIA) for the detection of immunoglobulin G antibodies to Helicobacter pylori was developed. A multicomponent antigen was prepared and used to coat...
Goldie, J, Veldhuyzen Van Zanten, S J, Jalali, S, Hollingsworth, J, Riddell, R H, Richardson, H, ...
We developed a buffered azide-free urea medium which is sensitive, specific, and nontoxic for rapid detection of Campylobacter pylori in gastric biopsies. Detection of urease produced by the organism...
Inhibition of urease activity but not growth of Helicobacter pylori by acetohydroxamic acid.
Goldie, J, Veldhuyzen Van Zanten, S J, Jalali, S, Richardson, H, Hunt, R H
The in vitro effects of acetohydroxamic acid (AHA), a potent urease inhibitor, were studied to determine the effect on the urease activity and growth of 38 strains of Helicobacter pylori. AHA in...
Helicobacter pylori: new developments and treatments
Veldhuyzen Van Zanten, S J, Sherman, P M, Hunt, R H
The authors highlight new developments in research on Helicobacter pylori. There is now consensus that all patients with newly diagnosed or recurrent duodenal or gastric ulcers who have a positive...

OBJECTIVES: To provide Canadian primary care physicians with an evidence-based clinical management tool, including diagnostic and treatment recommendations, for patients who present with...
Measuring quality of life in clinical trials: a taxonomy and review.
Guyatt, G H, Veldhuyzen Van Zanten, S J, Feeny, D H, Patrick, D L
Measurement of quality of life is becoming increasingly relevant to controlled clinical trials. Two basic types of instrument are available: generic instruments, which include health profiles and...
Indications for treatment of Helicobacter pylori infection: a systematic overview.
Veldhuyzen Van Zanten, S J, Sherman, P M
OBJECTIVE: To determine (a) the advantages and disadvantages of treatment options for the eradication of Helicobacter pylori and (b) whether eradication of H. pylori is indicated in patients with...
Veldhuyzen Van Zanten, S J, Sherman, P M
OBJECTIVE: To evaluate current evidence for a causal relation between Helicobacter pylori infection and gastritis, duodenal ulcer, gastric cancer and nonulcer dyspepsia. DATA SOURCES: A MEDLINE...
