OBJECTIVES:The prevalence of diagnosed celiac disease is <1 in 2,000 in the United States, but screening studies undertaken in European and other populations have revealed a much higher prevalence. The objective of this study was to determine the prevalence of celiac disease and the utility of screening in the general adult population of a geographically(More)
Kruppel-like factor (KLF) proteins are emerging as key regulators of lipid metabolism, diabetes, and the biosynthesis of immunological cytokines. However, their role in the synthesis of prostaglandins, widely known biochemical mediators that act in a myriad of cell biological processes remain poorly understood. Consequently, in this study a comprehensive(More)
BACKGROUND Environmental risk factors playing a causative role in Crohn's Disease (CD) remain largely unknown. Recently, it has been suggested that refrigerated food could be involved in disease development. We thus conducted a pilot case control study to explore the association of CD with the exposure to domestic refrigeration in childhood. (More)
Colorectal cancer (CRC) is one of the leading causes of cancer related mortality worldwide. Although young-onset CRC raises the possibility of a hereditary component, hereditary CRC syndromes only explain a minority of young-onset CRC cases. There is evidence to suggest that young-onset CRC have a different molecular profile than late-onset CRC. While the(More)
BACKGROUND Despite claims of rarity, some studies indicate that the prevalence of inflammatory bowel disease has increased in Iran during the past decades. Establishment of a registry and the clinical characteristics are presented in this study. METHODS Two hundred ninety-three patients with ulcerative colitis and 207 with Crohn's disease, referred to(More)
BACKGROUND Osteoporosis has been frequently reported in patients with inflammatory bowel diseases, especially Crohn's disease. METHODS All consecutive Crohn's disease patients who attended the GI Clinics at Shariati Hospital, Tehran, Iran, from 2004 to 2007 were evaluated. A BMD-DEXA assessment was performed for all patients. Among those patients(More)
The role and relevance of deamidated gliadin antibodies specific for celiac disease in gluten-sensitive ataxia/neuropathy is unknown. We investigated the association of celiac-specific serology with gluten-sensitive ataxia/neuropathy, in patients with and without gliadin-induced enteropathy. 51 patients with unexplained ataxia/neuropathy suspected to have(More)
Objective:Whereas few adenomas become cancer, most colorectal cancers arise from adenomas. Telomere length is a recognized biomarker in multiple cancers, and telomere maintenance mechanisms (TMM) are exploited by malignant cells. We sought to determine whether telomere length and TMM distinguish cancer-associated adenomas from those that are(More)
The majority of colorectal cancers (CRCs) arise from adenomatous polyps. In this study, we sought to present the underrecognized CRC with the residual polyp of origin (CRC RPO+) as an entity to be utilized as a model to study colorectal carcinogenesis. We identified all subjects with biopsy-proven CRC RPO+ that were evaluated over 10 years at Mayo Clinic,(More)
