“…pylori infection is currently considered a public health problem, since 50% of the world's population suffers from it and is related to gastric MALT lymphoma; the indiscriminate use of antimicrobial therapy has caused the emergence of antibiotic resistance, leading to a public health problem [16]. In Mexico the prevalence goes from 30 to 90% [17] and worldwide 50% [18,19].…”

Objective: Presentation of an acute appendicitis and non-Hodgkin lymphoma of lymphoid tissue associated with extranodal mucosa from the cecum clinical case. Introduction: The cecal appendix can be affected by Non-Hodgkin Lymphomas (NHL) by extension of the neoplasm; however primary appendicular lymphoproliferative processes are uncommon. The NHL of Mucosal-Associated Lymphoid Tissue (MALT) is exceptional. To establish the diagnosis of MALT, a morphological, molecular and immunohistochemical diagnosis is required, including molecular techniques that reflect B cell clones, PCR analysis or the identification of chromosomal abnormalities. Methods: 40 year old male, with 15 days of evolution of abdominal pain located in Right Lower Quadrant (RLQ) and associated symptoms like decreased appetite, nausea, and adynamia, who was firstly diagnosticated as an urinary tract infection treated as outpatient; upon his readmission, he was performed CT scan evidencing mesenteric panniculitis and thickening of the appendicular wall; he was surgically intervened finding edematous and congestive vermiform appendix with lower third perforation, and indurated cecum with 2 cm perforation from the appendicular base, performing right hemicolectomy with ileo-transverse mechanical anastomosis; he was discharged home 7 days after the postoperative period; the histopathological study and immunohistochemistry panel was compatible with MALT-type lymphoma, with lesion-free edges. Extension CT scans with no evidence of distant disease. He was sent to oncology for follow-up. Conclusion: It is important to get an established diagnosis in this rare pathology with molecular techniques and not only with histopathological cuts, since 30% of patients relapse.

“…Another cohort of children from Mexico was mainly detected with H. pylori based on stool antigen, which was the most feasible method to detect this infection, even in asymptomatic children [ 40 ]. Still, detecting H. pylori infection in children remains challenging since most are either asymptomatic or present unspecific symptoms such as abdominal pain, vomiting, nausea, or diarrhea [ 58 ].…”

Worldwide Prevalence and Risk Factors of Helicobacter pylori Infection in Children

2022

View full text Add to dashboard Cite

Helicobacter pylori is usually acquired during childhood. The reports from the last two decades pointed out a decrease in H. pylori prevalence across geographical areas worldwide compared to previously reported data. Most of the studies performed in America found an overall H. pylori infection prevalence of approximately 50%. The most important risk factors in America include being male, poor adherence or difficult access to treatment, and the lack of in-home water service. Despite the descending trend in prevalence worldwide, the overall prevalence in Africa remains very high (70%). Nevertheless, the prevalence of H. pylori in children without gastrointestinal who underwent screening was reported to be only 14.2%. The main risk factors in Africa are having a traditional pit or no toilet, poverty, birth order, source of drinking water, or being a farmer. Asia seems to have the widest variations in terms of H. pylori prevalence. Several risk factors were reported in Asia to be associated with this infection, such as lower income and educational level, house crowding, rural residence, ethnicity, the use of tanks as water supplies, alcohol drinking, active smoking, eating spicy food or raw uncooked vegetables, poor living conditions and sanitation. The overall prevalence of H. pylori infection in European children is almost 25%. Portugal has the highest prevalence of all European countries at 66.2% in children 13 years of age. The risk factors in European individuals consist of living in rural areas, eating unwashed fruits and vegetables, not washing hands after school, low parental education and unemployment, and short education duration. Further studies are required to identify the precise mechanisms involved in the discrepancies of H. pylori prevalence worldwide.

“…1,2 Intra-abdominal inflictions include peritonitis, intra-abdominal abscesses, appendicitis, colorectal cancer, ulcerative colitis, food poisoning, chronic atrophic gastritis, peptic ulceration and stomach cancer. [3][4][5] Pathogens associated with intra-abdominal infections include Escherichia coli, the Bacteroides fragilis group, and Clostridium species. 6,7 Bacteroides species are opportunistic bacteria that form part of the normal microbiota and are often associated with polymicrobial infections such as intra-abdominal, pelvic, genital, complicated skin and soft tissue, and bloodstream infections.…”

Antimicrobial activity and toxicity profile of selected southern African medicinal plants against neglected gut pathogens

et al. 2019

Anaerobes outnumber aerobic bacteria in the human gut. The most commonly isolated microorganisms in intra-abdominal infections include Escherichia coli, Peptostreptococcus micros as well as Bacteroides and Clostridium species. Several studies have been undertaken on southern African medicinal plant species and their antimicrobial efficacy against pathogens such as E. coli that cause stomach ailments. However, pathogens such as Helicobacter pylori, Fusobacterium varium as well as others have been neglected in medicinal plant antimicrobial research. The aim of this study was to evaluate the antimicrobial activity of selected medicinal plants documented for stomach ailments against neglected gut pathogens. A total of 102 aqueous and organic extracts were prepared from 40 different plant species. These plant samples were screened for antimicrobial efficacy against eight anaerobes and two microaerophilic strains using the micro-dilution antimicrobial assay. Plant extracts that displayed noteworthy antimicrobial activity against Clostridium perfringens were further evaluated for antibiofilm activity using the crystal violet staining assay. The toxicity profiles of plants that displayed noteworthy antimicrobial activity were evaluated using the brine shrimp lethality assay which revealed that most of the tested plant samples were non-toxic in nature, and the aqueous extracts proved to be safer. The organic extract of Lippia javanica leaf showed the best antimicrobial activity with a minimum inhibitory concentration of 0.5 μg/mL against C. perfringens. The organic extract of Salvia africana-caerulea displayed the best antibiofilm activity overall, at cell attachment (4 h) biofilm developmental stage with inhibition percentages of 82.8%.
