Eradication of gastric Helicobacter pylori ameliorates halitosis and tongue coating.

Background: The influence of gastric Helicobacter pylori infection on the development of oral pathoses remains unclear. The aim of this study is to examine the influence of gastric H. pylori infection on occurrence of halitosis and coated tongue.

Morphometric study of uninvolved rectal mucosa 10 cm and 20 cm away from the malignant tumor.

Recently, many details of the interplay between tumor cells and tumor-associated stromal elements leading to the progression of malignant disease were elucidated. In contrast, little is known about the role of uninvolved stromal tissue in the remote surrounding of the malignant tumor. Therefore, we performed a computer-aided morphometric study of rectal mucosa in samples taken 10 cm and 20 cm away from the malignant tumor during endoscopic examination of 23 patients older than 60 years.

Morphometric study of healthy jejunal and ileal mucosa in adult and aged subjects.

Small intestine mucosa is often affected with malabsorptive, autoimmune and inflammatory pathological processes. However, morphometric data on the healthy human small intestine mucosa, especially ileum, are scarce. We aimed to obtain histoquantitative data on the healthy jejunal and ileal mucosa and assess the effects of gender and ageing on these parameters.

Mechanism of diarrhea in microscopic colitis.

Aim: To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes, osmotic gap and pH.

Methods: Seventy-six patients were included: 51 with microscopic colitis (MC) (40 with lymphocytic colitis (LC); 11 with collagenous colitis (CC)); 7 with MC without diarrhea and 18 as a control group (CG). They collected stool for 3 d.

Circulating insulin-like growth factors in patients infected with Helicobacter pylori.

Objectives: The level of insulin-like growth factors (IGFs) and their binding proteins may change in acutely ill humans. The aim of this work was to examine the changes in the IGF system in patients suffering from infection induced by Helicobacter pylori (H. pylori).

Problems in screening colorectal cancer in the elderly.

Aim: To explore the problems in the screening of colorectal carcinoma in the elderly.

Methods: Three models of colorectal cancer prevention were examined: standard screening, active check-up of suspected cases and summons to have endoscopic check-up for previously diagnosed colorectal polyps. The study was performed among three groups of elderly individuals: Group 1 (167 cases), hospitalized asymptomatic individuals without symptoms in large intestines.
