Association between higher score of H pylori in histology and a positive stool-PCR make it a very useful test for detection of H pylori active infection in children. We also suggest that a simple stool-PCR method can be a useful test for detection of H pylori virulence genes in stool.
Pistacia atlantica is the main herbal medicine that has been widely used in the Middle Eastern and Mediterranean areas since ancient time. Pistacia atlantica has been used for multiple purposes like stomach diseases, renal disorders, wounds and coughs. The aim of this study is to review its botanical characterization, traditional applications, photochemistry effects and pharmacological activities. Data in this review article was gathered from credible pharmacopeias, electronic databases such as Web of Science, Science Direct, PubMed, EMBASE, Scopus, EBSCO, Google Scholar, SID and Iran Medex and textbooks of Persian medicine such as Canon of medicine (Ibn-e Sina, 980-1037 AD) and Makhzan-al-Advia (Aghili, 18th century). The keywords were searched in Persian and English books on medicinal plants and traditional medicine. The results showed that P. atlantica has many medicinal properties such as antioxidant, antidiabetic, antihyperlipidemic, along with others. It can also be effective in gastrointestinal diseases. Thus, different new drugs can be formulated based on P. atlantica for the management of various diseases.
Objective: To study the clinical presentation, histology and colonoscopic features of lower gastrointestinal polyps in Iranian children. Material and Methods: Medical reports of children with colorectal polyps were retrospectively reviewed from 1996 to 2005 at the Children’s Medical Center Hospital, Iran. A total of 563 cases were studied. Data related to age, sex, family history, signs and symptoms, the size, location, polyp types and associated lesions were collected and analyzed. Results: The mean age of children was 5.66 ± 2.88 years (range 2 months to 17 years), with a male-to-female ratio of 1.61:1.0. The highest incidence was between ages 2 and 10 years (85.1%). Rectal bleeding was the presenting symptom in 78.5% cases. The polyps were solitary in 94% of cases. A majority of polyps (86.3%) were juvenile and 86.7% located in the rectosigmoid area. Three percent of cases had a positive family history. One case of Turcot syndrome was also identified. Conclusion: Juvenile polyps remain the most common polyps in Iranian children. Although the presence of a solitary polyp in the rectosigmoid colon is more prevalent, in a significant number of cases they are multiple and located in proximal parts. Polyps must be removed even when asymptomatic because of their probable neoplastic potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
