Gastric cancers in Finnish patients after cure of Helicobacter pylori infection: A cohort study.

Helicobacter pylori infection is associated with gastric cancer. A total of 97% of the infected subjects have elevated levels of H. pylori antibodies.

Development of a new method to get a reliable powder flow characteristics using only 1 to 2 g of powder.

In powder technology, it is often important to directly measure real powder flow rate from a small amount of powder. For example, in pharmaceutical industry, a frequent problem is to determine powder flow properties of new active pharmaceutical ingredient (API) in an early stage of the development when the amount of API is limited. The purpose of this paper is to introduce a new direct method to measure powder flow when the material is poorly flowing (cohesive) and the amount of material is about 1 to 2 g.

A new rapid on-line imaging method to determine particle size distribution of granules.

The purpose of this research was to study the feasibility of the new image analysis method in the particle size determination of the granules. The method is capable of forming a three-dimensional topographic image of a sample surface from a digital picture. In the method, a flat granule bed surface was illuminated from three different directions, using the three primary colors (red, green, and blue).

Size of the peptic ulcer in Helicobacter pylori-positive patients: association with the clinical and histological characteristics.

Objective: Based on a large trial of Helicobacter pylori-positive peptic ulcer patients, we studied whether the size of the ulcer, along with other clinical and histological characteristics, has any effect on healing. We also studied the clinical and endoscopic characteristics associated with size of the peptic ulcer.

Material And Methods: A total of 333 consecutive patients with H.

Clinical significance of widespread gastric metaplasia in the duodenal bulb.

Background: All the risk factors of peptic ulcer disease are not thoroughly understood.

Goals: To assess duodenal gastric metaplasia (DGM) in relation to Helicobacter pylori status and endoscopy findings with special reference to the effects of highly selective vagotomy.

Study: The study population consisted of 1056 adult patients and an additional 154 patients who had had a highly selective vagotomy.

Helicobacter pylori eradication in the healing of atrophic gastritis: a one-year prospective study.

Objective: Whether gastric atrophy or intestinal metaplasia heals after successful treatment of Helicobacter pylori (H. pylori) infection is still a matter of controversy. The aim of this article was to clarify whether, after one year, H.

Association of Helicobacter pylori IgA antibodies with the risk of peptic ulcer disease and gastric cancer.

Aim: To compare the prevalence of Helicobacter pylori (H pylori) IgG and IgA antibodies between adult subjects, with defined gastric diseases, non-defined gastric disorders and those representing the population.

Methods: Data on H pylori IgG and IgA antibodies, determined by enzyme immunoassay, were analyzed in 3,252 subjects with DGD including 482 patients with gastric ulcer, 882 patients with duodenal ulcer, 1,525 patients with chronic gastritis only and 363 subjects with subsequent gastric cancer, 19,145 patients with NoDg and 4,854 POPUL subjects. The age-adjusted prevalences were calculated for 1- and 20-year age cohorts.

Helicobacter pylori eradication as the sole treatment for gastric and duodenal ulcers.

Objectives: It is uncertain whether eradication of Helicobacter pylori--without a prolonged suppression of acid secretion--is sufficient to allow healing of peptic ulcers. We evaluated whether eradication of H. pylori with no following anti-secretory medication then administered is sufficient for treatment of peptic ulcers.

Eradication of Helicobacter pylori improves the healing rate and reduces the relapse rate of nonbleeding ulcers in patients with bleeding peptic ulcer.

Objective: A causal relationship between Helicobacter pylori (H. pylori) and peptic ulcer complications remains obscure. The aim of this study was to determine the importance of H.
