ABSTRACT
The study was designed to evaluate the scope of applications of the new digital videoendoscopic NBI-technology for the diagnosis of chronic duodenitis (CD), the prevalence and clinical manifestations of this pathology. Of 287 patients with CD, 102 were examined using a GIF-H180 EVIS Exerall apparatus (Olympus, Japan) equipped with the NBI system. Control patients were examined with conventional fiber-optic and videoendoscopes GIF-Q49 and GIF-Q160 EVIS Exeral (Olympus, Japan). Evaluation encompassed endosopic signs of inflammation, its spread, and severity. It was shown that manifestations of inflammation of duodenic mucosa correlated with the endoscopic picture in the NBI regime and results of histological studies. The use of the NBI-technique in routine oesophagogastroduodenoscopy of patients with CD enhances efficiency of detection of even mild inflammatory reactions in duodenal mucosa from 20 to 72.5% (P < 0.05).

The study was designed to assess the value of a new NBI-based digital videoendoscopic system for the diagnosis of erosive and ulcerative lesions in the stomach and duodenum of 136 patients in comparison with 185 ones examined with the use of conventional fiber-optic and videoendoscopes. Patients of group 1 were examined using a GIF-H180 EVIS Exera-I apparatus ("Olympus", Japan), controls with GIF-Q40 and GIF-Q160 EVIS Exera-II endoscopes ("Olympus", Japan). Endoscopic signs of inflammation, its extent and severity were recorded. NBI endoscopy revealed perifocal inflammatory changes associated with ulcerative lesions in the stomach and duodenum as spots of different tones of blue. This method allowed for the detection of lesions not visualized by conventional techniques. The use of NBI technology for routine endogastroduodenoscopy in patients with erosive and ulcerative lesions in the stomach and duodenum improves visualization of even minor changes in gastric and duodenal mucosa (p < 0.05).

The aim of the study was to evaluate efficiency of a new endoscopic diagnostic tool based on the NBI-technology for the detection of Helicobacter pylori (Hp) content. A total of 294 patients with chronic inflammatory diseases of the stomach and duodenum were examined for the assessment of severity and extent of inflammatory processes. Staining intensity of gastric and duodenal mucosa in the NBI regime was shown to correlate with the degree of inflammation. Gastric metaplastic foci could be visualized due to their deep blue staining. Their distribution was unrelated to Ph occurrence and content. It is concluded that the use of the NBI technology for routine oesogastroduodenoscopy improves visualization of inflammatory changes in gastric and duodenal mucosa.

The aim of this work was to compare efficiency of a new digital endoscopic system in combination with the NBI technology and routine endoscopic examination of patients with chronic gastritis. 181 of the 831 patients with different forms of chronic gastritis were examined with a GIF-H180 Evis Exera-II apparatus (Olympus, Japan) coupled to the NBI system. The control group comprised 650 patients examined using conventional GIF-Q160 and GIF-Q160 Evis Exera-I fiberscopes (Olympus, Japan). Signs of inflammation, its severity and extent were evaluated. Significant correlation was revealed for the first time between inflammation of gastric mucosa, type of gastritis, endoscopic picture in the NBI regime, and results of histologic studies. Inflammation foci and sites of intestinal metaplasia were found to produce characteristic images in which they had different shades of lilac and deep blue respectively. Distribution of the stained foci corresponded to that of inflammation and/or metaplasia. It is concluded that the use of the NBI technology in routine oesophagogastroduodenoscopy improves diagnosis of intestinal metaplasia to 80-100% (p = 0.000).

Using the material of anthropologic examination of women of several professional groups some characteristics of postdefinitive ontogenesis have been studied. Relative and absolute enlargement of hand length on the background of decrease of stature in older age groups is marked. The differences in intra- and intergroup variability is assumed by the action of professional selection as well as specific static and dynamic loads on hand. Besides, the dynamics in involutive processes where one of the indexes is stooping posture has been analysed. Some professional differences in pattern and intensity of these changes are revealed.
