- Pneumatosis intestinalis a trap for the unwary: Case series and literature review. [Journal Article]
- IJInt J Surg Case Rep 2018 Nov 02; 53:214-217
- CONCLUSIONS: PI is a rare condition characterised by the presence of subserosal and submucosal gas filled cysts occurring anywhere in the gastrointestinal tract from the oesophagus to the anus. Numerous conditions have been associated with PI including bowel obstruction, infections, ischemia and there have been reported cases suggesting as association with Crohn's disease.PI is a condition that may manifest with a wide range of symptoms from mild abdominal pain to acute peritonitis. Its treatment is generally medical and even with radiological evidence of perforation laparotomy may not be indicated if the patient is clinically well.

Quality of life is an important outcome indicator to evaluate whether treatment is successful or not. Chronic gastritis leads to ongoing deterioration of subjectively perceived quality of life. There are several generic measures, but they are not developed particularly to assess chronic gastritis problems. The Quality of Life Instruments for Chronic Diseases-Chronic Gastritis (QLICD-CG V2.0) questionnaire is a 39-item, multi-dimensional, self-report instrument to assess chronic gastritis patients' perception of their health related quality of life in four domains. The instrument was developed in China. The current study aimed to evaluate the psychometric properties of the QLICD-CG V2.0. 194 patients with chronic gastritis were enrolled from 4 hospitals in China. The QLICD-CG V2.0 was administered to patients by trained research assistants. In addition, their demographic characteristics were also recorded. The psychometric testing included construct validity, convergent validity, discriminant validity, test-retest, and responsiveness. The results showed good internal consistency and acceptable floor and ceiling effects (Cronbach's alpha range from 0.80 to 0.93). CFA showed that the instrument structure has a reasonable fitness (RMSEA = 0.063, 95%CI = [0.057 0.079], CFI = 0.93, GFI = 0.95, SRMR = 0.028). The convergent validity was considered appropriate, with 38 of the 39 items correlated stronger with their assigned scale than a competing scale, except for GPS1. Known groups comparisons showed that the QLICD-CG V2.0 discriminated well between subgroups on the basis of gender, marriage status, and economy status, thus providing evidence of discriminative validity. Convergent validity testing revealed that the QLICD-CG V2.0 domain scores correlated significantly with SF-36 dimension scores, which ranged from 0.21 to 0.58. Test-retest coefficients were satisfactory. A majority of intraclass correlation coefficients were above 0.70, except the psychological domain (0.60) and the items of social support/security (0.61). Responsiveness was tested on 157 patients. Significant differences were found on all QLICD-CG V2.0 domains, between baseline responses and after a treatment, except for the items of appetite and sleep. Robust sensitivity to change was observed. The QLICD-CG V2.0 appears to be a valid and reliable instrument to measure QOL in chronic gastritis patients. Scores were reproducible.

The association between gastroesophageal reflux disease (GERD) prevalence and its risk factors in an area with low Helicobacter pylori prevalence is important to clarify. We analyzed the prevalence of GERD and risk factors in an area of Indonesia with low prevalence of H. pylori infection. We recruited 104 dyspeptic patients who underwent endoscopy in Surabaya. Patients were diagnosed with GERD based on the Los Angeles classification. We evaluated gastric biopsy specimens and measured serum pepsinogen levels. Interleukin polymorphisms were evaluated by polymerase chain reaction-restriction fragment length polymorphism. Of 104 patients, 56 (53.8%) were endoscopically found to have GERD, with most categorized as grade A; 48 (46.2%) were classified as non-GERD. Higher economic status, smoking, and a history of proton-pump inhibitor use significantly increased the risk of GERD. GERD Questionnaire scores showed a positive correlation with GERD (P < 0.001). An association was found between antral atrophic gastritis and GERD (P = 0.030), and patients with GERD more frequently had severe antral atrophy than nonerosive reflux disease (P = 0.018). We found an association between pepsinogen I/II levels and GERD (P = 0.047), but with low accuracy. IL-1β -511 TT and CT were predominant among the IL-1β -511 genotypes, and IL-8-251 AT and TT were predominant among the IL-8-251 genotypes. In conclusion, we found a high prevalence of GERD in an area with low prevalence of H. pylori infection, which could be associated with acid reflux. Smoking, history of proton-pump inhibitor use, and higher economic group significantly increased the risk of GERD.

Gastric cancer (GC) is the second most common cause of cancer death worldwide but could be more curable if diagnosed at an earlier stage. At present, the capability to predict the efficaciousness of molecular diagnosis for GC for each patient remains elusive. The purpose of this study was to identify tumor biomarkers through systems analysis of multigene predictors exploiting the available data resource. In this study, we investigated the top 10% overexpressed genes in GC from five data sets of the Oncomine platform, with 265 GC samples versus 174 normal gastric mucosa samples. Sixteen candidate genes were identified as predictors of GC, of which 14 genes were verified through the comparison of expression levels in specimens from normal (chronic gastritis, 21 samples) and GC groups (38 samples). In addition, unique molecular portraits of diffuse adenocarcinoma (DA), intestinal adenocarcinoma (IA), and mixed adenocarcinoma (MA) were studied through Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis, where DA showed higher extracellular matrix alteration while IA and MA showed higher cell-cycle alteration than other types. We also found that the elevated expressions of genes during GC progression were independent of gene mutations, and high core-binding factor subunit β expression is correlated with a high overall survival rate in GC patients. Our research may provide an efficient clinical diagnosis of GC at an early stage with high accuracy and thus help improve the overall survival rate through early therapeutic interventions.

Malanga (Xanthosoma sagittifolium) is used as a medicinal food for infant development and gastritis. We compared the physicochemical properties and gut microbial effects of malanga versus potato (Solanum tuberosum) using nutritional analysis, rheometry, in vitro TNO Intestinal Model, and C57Bl/6J mouse models. Malanga was characterized by higher starch (70.7% v. 66.3%), lower amylose:amylopectin (0.33 v. 0.59), higher free sugar (5.44% v. 3.23%), lower viscosity (271.0 v. 863.0 mPa.s), and higher bioaccessible and bioavailable sugar (0.89 v. 0.11 g bioaccessible sucrose per 20 g load in vitro; blood glucose levels of 129.1 v. 95.2 and 133.8 v. 104.3 mg/dL after 20 and 60 min in vivo). Gut microbiota of mice fed a high fat diet containing 20% malanga for 14 d exhibited significantly higher α diversity than those fed 20% potato, indicating that minor physicochemical differences between similar tuber crops are associated with significantly different effects on the gut microbiome.

Helicobacter pylori (H. pylori) infection is associated with an inflammatory response in the gastric mucosa, leading to chronic gastritis, peptic ulcers, and gastric cancer. Increased T-cell infiltration is found at sites of H. pylori infection. The CCR6+ subset of CD4+ regulatory T cells (Tregs), a newly characterized subset of Tregs, has been reported to contribute to local immune inhibition. However, whether CCR6+ Tregs are present in H. pylori gastritis, and what their relationship is to disease prognosis, remains to be elucidated. In this study, gastric infiltrating lymphocytes were isolated from endoscopic biopsy specimens of H. pylori gastritis patients and analyzed. We found that in gastric infiltrating lymphocytes, CCR6+ CD4+ CD25high Tregs, which express high levels of CD45RO, are positively associated with more severe inflammation in gastric mucosa during H. pylori infection. Furthermore, the frequency of CCR6+ Tregs in gastric infiltrating lymphocytes, but not CCR6- Tregs, is significantly increased in inflamed gastric tissues, which is inversely correlated with significantly lower expression of IFN-γ+ CD8+ T cells. We also found that the frequency of CCR6+ Tregs is positively correlated with the frequency of CD4+ IFN-γ+ T cells. In addition, the frequency of CCR6+ Tregs, but not that of CCR6- Tregs, is significantly correlated with increased inflammation in H. pylori gastritis. This study demonstrates that immunosuppression in H. pylori gastritis might be related to the activity of CCR6+ Tregs, which could influence disease prognosis.
