According to the results of some studies, most patients with dyspepsia are simultaneously suffering from gastric polyps. We aimed to clarify the association of gastric polyp and dyspepsia in an Iranian population.</pre> <pre><strong>Materials and methods</strong>: We enrolled 2772 dyspeptic and 1294 non-dyspeptic subjects in this cross-sectional study, who referred to the gastrointestinal clinic at Ayatollah Taleghani Hospital in Tehran from2016 to 2018.All subjects underwent upper gastrointestinal (GI) endoscopy andpatients with GI malignancy, severe GI bleeding and history of GI surgery excluded from study. They were evaluated for age, sex, endoscopicfindings, gastric polyp (GP) count, size and localization, diagnosticmethods used for histology, and polyp features. The relationshipbetween gastric polyp and dyspepsia was alsoevaluated.</pre> <pre><strong>Results</strong>: In 4066 consecutive upper GI endoscopy in patients with and without dyspepsia, 129 patients (3.2%) had gastric polyps (GPs).The prevalence of GPs was 3.04% and 3.32% in with and without dyspepsia subjects, respectively. There was no observed statistically significant relationship between GPs and dyspepsia (<em>P</em>=0.709). Hyperplastic polyps(HPs)were the most common pathologic form in patients with and without dyspepsia in 53.5% and 34.9% of patients, respectively. The most common location was the gastric antrum polyps (76.7%) and the common size of the polyps was between 5-10 mm in (80.6%) patients.</pre> <p><strong>Conclusion</strong>: In the present study, there was no statistically significant difference within the pathologic findings of gastric polyp in terms of dyspepsia.Hyperplastic polyps(HPs) are the most common type of pathologic stomach polyps and it is maybe high due to the highfrequency of Helicobacter pylori(H. pylori) infection in our country.</p> 2020-09-05T00:00:00+00:00 Copyright (c) 2020 School of Medicine Students' Journal https://journals.sbmu.ac.ir/smsj/article/view/30455 Viral Outbreaks of SARS-CoV1, SARS-CoV2, MERS-CoV, Influenza H1N1, and Ebola in 21st Century; A Comparative Review of the Pathogenesis and Clinical Characteristics 2020-09-12T16:26:17+00:00 Fateme Sadat Rahimi T.rahimi@sbmu.ac.ir Siamak Afaghi Siamak.afaghi@sbmu.ac.ir Farzad Esmaeili Tarki Farzad.esmaeili.t@sbmu.ac.ir Kian Goudarzi Kiangoudarzai1996@gmail.com Nasser Malekpour Alamdari nassermalekpour@gmail.com <p> </p><p>Throughout the past twenty years, humankind had its fair share of challenges with viral epidemics. In late December 2019, a zoonotic member of the coronaviruses was responsible for the COVID-19 outbreak of viral pneumonia in Wuhan, China. As a worldwide crisis, meanwhile, conclusive prevention or therapy has yet to be discovered, the death toll of COVID-19 has exceeded 278000 by May 11<sup>th</sup>, 2020. Alike other members of Coronavirus family such as MERS and SARS-CoV-1, SARS-CoV-2 provokes influenza-like syndrome which might further progress to the severe state of acute respiratory disease in some patients. Comparably, in 2009 the H1N1 influenza outbreak affected countless people by manifestations of respiratory system involvement. Additionally, Ebolavirus, as a member of the Filoviridae family, had also made a global catastrophe by causing hemorrhagic diseases in the past twenty years. The unknown intrinsic nature of SARS-CoV-2, as a great missing piece of this pandemic puzzle, has had physicians to empirically test the possibly efficacious agents of the former viral epidemics on the COVID-19 cases. Here, the current knowledge in SARS-CoV-2 clinical features, transmissibility, and pathogenicity are all summed up as against the other emerging viruses in the last two decades, and the data crucially required for a better management of the illness has been spotlighted.</p> 2020-07-11T00:00:00+00:00 Copyright (c) 2020 School of Medicine Students' Journal
