Abstract
Association of Helicobacter pylori with pathogenesis of gastrointestinal disorders (including gastritis in children with special endoscopic anteronodular) have significant importance in prognosis of infection resulting from this bacteria in children. However, in this research it was found that there is significant and clear correlation between nodular anteritis (in endoscopy) and active presence of lymphoid follicle (in histology findings with replacement of H.pylori) was noticed in children. In this research 14 persons (34.1%) out of total patients were positive. The average age of positive H.pylori patients was clearly higher than negative H.pylori patients. So increase of possible infection occurrence together with increase of age in children was confirmed. Meanwhile, there is significant relationship between presence of bacteria and clinical symptoms particularly epigastric pain, vomiting, and nausea. One of the other results of this study was confirming the relationship between history of gastrointestinal disorders in immediate family members and infection resulting from H.pylori in patients.

Abstract
In the present research work, a specific 285 bp DNA fragment was used for detection of Mycobacterium Tuberculosis complex. 100 samples were chosen randomly from sputum specimens that were negative with conventional methods (direct smear, culture, and radiometry), and examined by PCR 7 cases of them were positive. Also, 20 sputum specimens were obtained from suspected patients to tuberculosis, and examined by three methods (culture, radiometry and PCR). The sensitivity of PCR compared with culture and radiometry was 100%, the specificity of PCR compared with culture was 91.66%, and compared with radiometry was 68.75%. Therefore, results of PCR revealed, this method is more sensitive, specific and rapid and it can detect ycobacterial infectious agents within one day period.

Abstract
Background: Hyperuricemia is one of the oncologic emergency that occurs most often in patients with hematologic disorders particularly leukemia and high-grade lymphoma. This study was conducted in order to determine the prevalence of hyperuricemia with respect to prophylactic treatment (in particular allopurinol) in patients with lymphoproliferative disease in the pediatric hematologic ward of Imam Khomeini Hospital, Tehran.
Methods: In this retrospective cross-sectional study, 316 children (75 females, 241 males) under the age of 12 years participated. Among the subjects, 66 patients (20.9%) had lymphoma and 250 patients (79.1%) had leukemia.
Results: Of the 56 (17.7%) patients diagnosed with hyperuricemia, 13 with lymphoma (19.7%) and 43 (17.2%) with acute lymphoblastic leukemia, 52 patients showed hyperuricemia after induction of chemotherapy (p<0.001). Hyperuricemia was more prevalent in patients with more advanced disease (50.9% in stage IV, p<0.001). Hyperuricemia was more frequent in male patients (p<0.001). Among the 217 patients who had received prophylaxis (hydration, alkalization, allopurinol), 19 (8.7%) subjects had hyperuricemia compare to 37.3% in the group of patients who did not receive prophylactic treatment (p<0.001).
Conclusion: From the literature reviewed, a recombinant form of the urate oxidase enzyme (rasburicase) is a safe and effective alternative to allopurinol to rapidly control plasma uric acid concentrations in patients with hematologic malignancy at high risk for tumor lysis during induction of chemotherapy. In this respect, we recommend a prospective study to compare allopurinol and rasburicase in children with leukemia and lymphoma.

Abstract
Background: Helicobacter pylori (Hp) infection often occurs in childhood and adolescence, with the frequency increasing with age. Hp infection is associated with insufficient hygiene, overcrowding and low socioeconomic status. Although declining in developed countries, children in the developing countries continue to have a high prevalence of Hp infection. As the association of Hp infection with chronic abdominal pain is not ubiquitously accepted, in this study we investigate the significance of endoscopic finding associated with Hp infection in children with abdominal tenderness.
Methods: This cross-sectional study included 1,665 healthy children, aged 6 to 12 years, in whom Hp infection was evaluated using the IgG anti-H. pylori test. Hp-positive children with epigastric tenderness underwent upper gastrointestinal (GI) endoscopy. Urease activity of gastric mucosal biopsies was measured. The presence and density of Hp organisms, the presence of follicular gastritis, and the nature of inflammation and gastritis activity were assessed by histologic examination.
Results: Of 1665 children, 429 (26%) subjects (51% girls, 49% boys) were seropositive for H. pylori. There was a significant association between Hp infection and older age (p<0.001) and male/female ratio (p<0.05). Epigastric tenderness was detected in 39 children (1%), 29 of whom underwent upper GI endoscopy. Nodular gastritis with antral erythema was the most common endoscopic finding (26/29 89.7%). Histological findings revealed that, in all cases with endoscopic nodularity, lymphoid follicles were present. Bacterial density was low in 13 (44.8%), moderate in 14 (48.2%) and high in 2 (7%) subjects.
Conclusion: The findings of the present study demonstrated that antral nodularity is the most common feature in children with Hp infection and epigastric tenderness was significantly associated with histological findings of lymphoid follicles.

Abstract
Background: Coronary artery ectasia (CAE) is dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent normal coronary artery. The incidence of coronary artery ectasia is distinct in different countries that can be found in 1.2% to 5% of angiographic examinations.
Methods: This is a retrospective study that was conducted from September 2019 to February 2020 in Kermanshah University of Medical Sciences and the results were reported briefly. To obtain the desired articles, electronic searches were conducted in databases including the Scopus, PubMed, and Science Direct databases without time limited until October 2019. The keywords used were Coronary Artery Ectasia AND (Diabetes OR "Diabetes Mellitus"). This was done by two individuals separately and the final results were confirmed by a third person. Mixed method appraisal tool (MMAT) was used to evaluate the quality of studies. The structure of writing and the process of performing and reporting the study are based on the PRISMA checklist.

Results: Based on the search strategy carried out at PubMed, Scopus and Science Direct databases, 106 studies were found, which resulted in 24 articles being analyzed based on inclusion and exclusion criteria of which three were conducted in China, 18 in Turkey and one in Sweden, Egypt, and France. Finally, 24 articles were analyzed and the results showed a direct and effective relationship between diabetes mellitus and CAE (OR=1.19, CI: 0.94, 1.51).
Conclusion: Based on these results, the risk of CAE in subjects with diabetes mellitus was 19% higher than in subjects without diabetes mellitus.
