Chronic gastritis is a persistent inflammation of the gastric mucosa. The Sydney System is the most widely used classification of this disease but it does not allow a ranking of patients according to the evolutionary potential of the disease, unlike the classifications: “Operative Link On Gastritis Assessment” (OLGA) and “Operative Link on Gastritis Intestinal Metaplasia Assessment” (OLGIM). Our goals are to apply and evaluate the three classifications: the Sydney System, OLGA and OLGIM and to draw possible correlations. This is a retrospective, descriptive, single-center study performed on all cases of chronic gastritis, diagnosed at the laboratory of Pathological Anatomy Unit of Joseph Ravoahangy Andrianavalona University Hospital from January 1, 2013 to December 31, 2017. A review and application of the three main classification systems was performed on each case. We included 298 cases. The mean age was 50.85 years. The sex ratio was 1.48. The high-risk stages according to the “Operative Link On Gastritis Assessment” (OLGA) system and the “Operative Link on Gastritis Intestinal Metaplasia Assessment” (OLGIM) system were 0.67% and 2.68%, respectively. We observed a correlation between the two systems with discordance of 5%. The use of the two new systems allows the assessment of the progressive potential of gastritis in patients at risk of developing gastric cancer. For optimal effectiveness of both classifications, biopsies should be performed according to the Sydney System recommendations. 展开更多

The fluid flow history during diagenesis of the Lower Triassic Bulgo sandstone has been investigated through integrated analyses of petrography, stable isotope and fluid inclusion. Combined application of these techniques was intended to constrain the temperature, timing, chemistry and source of pore fluids during diagenetic cementation events in the Lower Triassic Bulgo sandstone. The diagenesis proceeded in two different flow regimes: early dynamic fluid flow regime and late slow static fluid flow regime. The former was characterized by a slight increase of δ( 18 O) of pore waters form estimated -15×10 -3 to -14×10 -3 with the temperature increasing from ~10 ℃ to ~75 ℃. During early diagenesis, early clays and pore filling carbonates precipitated from the pore waters. The late slow flow/static fluid regime was characterized by a rapid 18 Oenrichment process. δ( 18 O) of pore waters increased from -14×10 -3 to -5×10 -3 with the temperature increasing from 75 ℃ to 110 ℃. During the late diagenesis, kaolin (generation Ⅱ), quartz and illite crystallized. Oil migrated to the sandstones of the Bulgo sandstone during quartz cementation. 展开更多

The directional-spectrum model of internal waves in shallow seas given by Xiao and Fang (1991 )was used to analyze the observation data gathered in April, 1981, in the sea off Sydney,Australia.Some reasonable results were obtained. The energy ratio between Wavemodes 1 and 2 was about 2 for most frequencies and was up to 8 at o = 0.23 cph.Wave components with frequencies 0.1-0.8 cph were generated in the deep sea,and propagated onshore,while those with frequencies higher than 0.8 cph were locally generated by the interaction between longshore currents and bottom topography.Several surveys were carried out in the sea off Sydney, Australia (Cresswell, 1974,Cresswell and Boland, 1981 ,and Fang,Boland and Cresswell, 1984). The survey performed in April 1981 by Fang, Boland and Cresswell (1984) was outstandingly successful. To draw some deterministic and stochastic characters of internal waves, Fang, Boland and Cresswell (1984) and Fang (1987) analyzed these data gathered in 1981 and obtained some 展开更多

Objective: To determine the prevalence of H. pylori induced gastritis and its association with development of chronic inflammation and carcinoma with reference to updated Sydney classification, to ensure the proper diagnosis and timely treatment. Methods: This was a cross sectional study conducted at the Department of Pathology, Dow Diagnostic Reference and Research Laboratory for the year 2018. Analysis of about 726 gastric biopsy specimens was performed to identify the epidemiological status of the disease. On the other hand, 100 of the specimens were analysed according to Sydney classification to ensure the accurate diagnosis of the gastritis and related disorders. Out of 726 biopsy samples positive samples for carcinoma were investigated in detail histological features. Giemsa stain was used to visualize the h pylori bacteria and the sections of biopsies were subjected to haematoxylin and eosin staining for histological analysis. Results: Out of 727 cases, H. pylori was found in 492 (67.8%) patients. About 1.79% (13) cases were identified as adenocarcinoma, 0.27% (2) squamous cell carcinoma and 0.13% (1) as B cell non Hodgkin lymphoma. Results of Sydney classification. The degree of chronic inflammatory activity was 57% mild;38% moderate and 3% severe out of a total of 67% cases in an active phase of Hp gastritis. Hp-associated gastritis was the most common form of chronic gastritis, without intestinal metaplasia and with mild activity. The association of h pylori with mild inflammation and Neutrophilic infiltrates of the lamina propria, pits, or surface epithelium was statistically significant (p value Conclusion: The frequency of H. pylori infection is common in our population but the infection is mild to moderate and its Sydney classification reveals that early diagnosis may prevent the later complication. 展开更多

BACKGROUND New markers are needed to improve the effectiveness of serological screening for atrophic gastritis.AIM To develop a cost-effective method for serological screening of atrophic gastritis with a high level of sensitivity.METHODS Of the 169 patients with atrophic gastritis,selected by the visual endoscopic Kimura-Takemoto method,165 showed histological mucosal atrophy using the updated Kimura-Takemoto method.All 169 patients were examined for postprandial levels of gastrin-17(G17)and pepsinogen-1(PG1)using Gastro-Panel®(Biohit Plc,Helsinki,Finland).RESULTS We used the histological standard of five biopsies of the gastric mucosa,in accordance with the Kimura-Takemoto classification system to assess the sensitivity of G17 in detecting gastric mucosal atrophy.We also compared the morphofunctional relationships between the detected histological degree of gastric mucosal atrophy and the serological levels of G17 and PG1,as the markers of atrophic gastritis.The sensitivity of postprandial G17 was 62.2%for serological levels of G17(range:0-4 pmol/L)and 100%for serological G17(range:0-10 pmol/L)for the detection of monofocal severe atrophic gastritis.No strong correlation was found between the levels of PG1 and degree of histological atrophy determined by the Kimura-Takemoto classification system to identify the severity of mucosal atrophy of the gastric corpus.In the presented clinical case of a 63-year-old man with multifocal atrophic gastritis,there is a pronounced positive long-term dynamics of the serological marker of atrophy-postprandial G17,after five months of rennet replacement therapy.CONCLUSION Serological screening of multifocal atrophic gastritis by assessment of postprandial G17 is a cost-effective method with high sensitivity.Postprandial G17 is an earlier marker of regression of atrophic gastritis than a morphological examination of a gastric biopsy in accordance with the Sydney system.Therefore,postprandial G17 is recommended for dynamic monitoring of atrophic gastritis after treatment. 展开更多

AIM: To investigate the mutation of p53 immunohistochemically in non-tumorous gastric mucosa with H pylori infection before and aEer H pylori eradication therapy. METHODS: 53 subjects (36 male, 17 female, mean age ± SEM, 57.1 ± 12.1) undergoing endoscopic examination were included in this study. 42 of 53 patients were H pylori-positive, and 11 were H pylorinegative. All H pylori-positive patients had successful eradication therapy. Biopsy specimens were taken from five points of the stomach, as recommended by the updated Sydney system. Immunohistochemical studies were performed by using primary antibodies against p53 (DO-7 and PAb240). RESULTS: p53 (DO-7 and PAb240) immunoreactivity was shown in the neck region of the gastric pits, however, quite a few cells were found to be immunopositive for p53 (PAb240)in the Hpylori-infected gastric mucosa. The proportion of patients immunopositive for p53 (PAb240) was significantly reduced 6 mo after eradication [28/42 (66.7%) to 6/42 (14.3%)] (P 〈 0.05), while the biopsies taken from H pylori-negative patients showed no immunoreactivity for p53 (PAb240). p53 (PAb240)-positive patients were divided into two groups by the number of positive cells detected: one with more than six positive cells per 10 gastric pits (group A, n = 12), and the other with less than five positive cells per 10 gastric pits (group B, n = 30). Atrophy scores in group A were significant higher than those in group B at the greater curvature of the antrum (group A: 2.00 ± 0.14 vs group B: 1.40 ± 0.15, P = 0.012), the lesser curvature of the corpus (group A: 2.00 ± 0.21 vs group B: 1.07 ± 0.23, P = 0.017), and the greater curvature of the corpus (group A: 1.20 ± 0.30 vs group B: 0.47 ±0.21, P = 0.031). Group A showed significant higher intestinal metaplasia scores than group B only at the lesser curvature of the antrum (group A: 2.10 ± 0.41 vs group B: 1.12 ± 0.29, P = 0.035). CONCLUSION: H pylori-associated chronic gastritis expressed the mutant-type p53, which was significantly associated with more severe atrophic and metaplastic changes. Hpylori eradication led to a significant reduction in the expression of the mutant-type p53. It is considered that H pylori-infected chronic gastritis is associated with a genetic instability that leads to gastric carcinogenesis, and H pylori eradication may prevent gastric cancer. 展开更多

BACKGROUND The Updated Sydney system for visual evaluation of gastric mucosal atrophy viaendoscopic observation is subject to sampling error and interobserver variability.The Kimura-Takemoto classification system was developed to overcome theselimitations.AIMTo compare the morphological classification of atrophic gastritis between theKimura-Takemoto system and the Updated Sydney system.METHODSA total of 169 patients with atrophic gastritis were selected according to diagnosisby the visual endoscopic Kimura-Takemoto method. Following the UpdatedKimura-Takemoto classification system, one antrum biopsy and five gastriccorpus biopsies were taken according to the visual stages of the Kimura-Takemoto system. The Updated Kimura-Takemoto classification system was thenapplied to each and showed 165 to have histological mucosal atrophy;theremaining 4 patients had no histological evidence of atrophy in any biopsy. The Updated Kimura-Takemoto classification was verified as a referencemorphological method and applied for the diagnosis of atrophic gastritis. Addingone more biopsy from the antrum to the six biopsies according to the Updated Kimura-Takemoto classification, constitutes the updated combined Kimura-Takemoto classification and Sydney system.RESULTSThe sensitivity for degree of mucosal atrophy assessed by the Updated Sydneysystem was 25% for mild, 36% for moderate, and 42% for severe, when comparedwith the Updated Kimura-Takemoto classification of atrophic gastritis formorphological diagnosis. Four types of multifocal atrophic gastritis wereidentified: sequential uniform (type 1;in 28%), sequential non-uniform (type 2;in7%), diffuse uniform (type 3;in 23%), diffuse non-uniform (type 4;in 24%), and"alternating atrophic – non-atrophic" (type 5;in 18%). The pattern of the spread ofatrophy, sequentially from the antrum to the cardiac segment of the stomach,which was described by the Updated Kimura-Takemoto system, washistologically confirmed in 82% of cases evaluated.CONCLUSIONThe Updated Sydney system is significantly inferior to the Updated Kimura-Takemoto classification for morphological verification of atrophic gastritis. 展开更多
