Identifying the etiology of chronic diarrhoea might be challenging in some patients, and before a diagnosis is made these patients may spend a substantial length of time with unresolved symptoms leading to uncertainty and anxiety that is severely impairing their life quality. A 45-year-old female was referred by her general practitioner with a 5-year history of increasingly frequent episodes of cyclical diarrhoea, vomiting, abdominal pain and intermittent palpitations. Contrast CT Abdomen/Pelvis revealed a 36x33x46 mm mass in the aorto caval region of her retro-peritoneum, just above the bifurcation...

Lithophagia is a type of pica that might be resulted from Iron Deficiency Anemia (IDA) which is the frequent presenting signs of Celiac Disease (CD). A 5-year-old child with a two year history of the lithophagia with a, refractory IDA, abdominal distention and constipation. The child did not grow well and had failure to thrive. With suspicion to CD, TTg IgA level was measured and due to an incearse of TTg IgA level the patients were undergone esophagogastrodeudonoscpy and jejunal biopsy. The biopsy showed severe villous atrophy and an increase in limphoplasma cells...

AIM: To survey person centered survival rate in population based screening program by an intelligent clinical decision support system. BACKGROUND: Colorectal cancer is the most common malignancy and major cause of morbidity and mortality throughout the world. Colorectal cancer is the sixth leading cause of cancer death in Iran. In this survey, we used cosine similarity as data mining technique and intelligent system for estimating survival of at risk groups in the screening plan...

AIM: The aim of this study was to assess the association between survival of patients with colorectal cancer and prognostic factors in a competing risk parametric model using Weibull distribution. BACKGROUND: The prognosis of colorectal cancer is relatively good in terms of survival time. In many prognostic studies, patients may be exposed to several types of competing events. These different causes of death are called competing risks. METHODS: Data was recorded from 372 patients with colorectal cancer who registered in the Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences (Tehran, Iran) from 2004 to 2015 in a retrospective study...

AIM: The aim of the present study was to evaluate the different doses of Butyric acid (BA) and Arsenic (As) in liver mitochondria oxidative stress and pancreatic islet insulin secretion of male mouse. BACKGROUND: BA is found in many foods and As as a toxic metal is present in drinking water. They can induce oxidative stress in tissues. METHODS: In this experimental study, Liver mitochondria were isolated by administration of the different centrifugation method and pancreatic islets were isolated by collagenase method...

AIM: To evaluate the association between biochemical, virologic and histologic features in patients with HBeAg-negative chronic hepatitis B (CHB). BACKGROUND: Hepatitis-B e-antigen (HBeAg)-negative is common in Iran, is progressive with poor prognosis. Therefore, it seems necessary to perform a comprehensive evaluation of different spectrum of laboratory measurements accompanying histological findings. METHODS: HBeAg- negative CHB patients referring to two university hospitals during two years were enrolled...

AIM: This study aimed to investigate the association of IFN- γ +874 (T/A) polymorphism with susceptibility to chronic HBV infection in the Syrian population. BACKGROUND: Accumulating evidence indicate that the inadequate immune responses are responsible for HBV persistency. Therefore, polymorphisms in genes encoding the cytokines, which are responsible for regulation of the immune response, can affect the course and outcome of the infection. The IFN-γ +874 T/A polymorphism affects the expression of IFN-γ, which has been shown to be crucial to HBV clearance...

AIM: The present study investigated the anti-tumor activity of Imatinib mesylate through modulation of NM23 gene expression in human hepatocellular carcinoma (HepG2) cell line. BACKGROUND: Hepatocellular carcinoma (HCC) is considered to be the third leading cause of cancer related death worldwide. Down regulation of NM23, a metastasis suppressor gene, has been associated with several types of malignant cancer. Recently, effects of Imatinib mesylate, a first member of tyrosine kinases inhibitors, were indicated in research and treatment of different malignant tumors...

Nahal Eshghifar, Naser Farrokhi, Tahereh Naji, Mohammadreza Zali
Colorectal cancer (CRC) is mostly due to a series of genetic alterations that are being greatly under the influence of the environmental factors. These changes, mutational or epigenetic modifications at transcriptional forefront and/or post-transcriptional effects via miRNAs, include inactivation and the conversion of proto-oncogene to oncogenes, and/or inactivation of tumor suppressor genes (TSG). Here, a thorough review was carried out on the role of TSGs with the focus on the APC as the master regulator, mutated genes and mal-/dysfunctional pathways that lead to one type of hereditary form of the CRC; namely familial adenomatous polyposis (FAP)...

Reza Bagherzadeh Saba, Amir Sadeghi, Neda Rad, Mohammad Taghi Safari, Farnoush Barzegar
Lipomas of the colon are relatively rare benign soft tissue tumors derived from mature adipocytes of mesenchymatic origin. During colonoscopy, surgery or autopsy they are generally discovered incidentally. Most cases are asymptomatic, with a small tumor size, and do not need any special treatment. However, in the cases with larger in size of tumor some symptoms such as anemia, abdominal pain, constipation, diarrhea, bleeding, or intussusception may be presented. We reported a 47-year-old woman with colonic intussusception in the descending colon caused by colonic lipoma and diagnosed after surgical exploration for obstructive colonic mass...

Hepatobiliary cystadenomas (HBC) is a rare neoplasm which comprising less than one percent of liver cystic neoplasms. Although it's known as a benign tumor, but they have a potential for neoplastic transformation. Making a proper diagnosis and ruling out of other differential diagnosis is important because of different treatment. In the present study, we described a case of HBC manifested as idiopathic dominant biliary stricture in common hepatic duct (CHD), on the basis of spiral CT scan and MRI, and elevated CA19-9...

AIM: Prevalence and risk factors associated with intestinal parasites among children ≤ 12 years old in Nahavand county western Iran, was the objective of this search. BACKGROUND: Intestinal parasites (IPs) are important health problems among most societies. METHODS: This cross sectional study was carried out during 6 months from April to September 2014 in Nahavand County western Iran. Fecal samples were collected from 500 children suffering from gastrointestinal disorders (GIDs) and examined by macroscopy and microscopic (using saline and iodine wet mount, formalin-ether sedimentation, Trichrome and modified Ziehl Neelsen staining) methods...

AIM: The present study was aimed to evaluate E. granulosus genotypes isolated from goats using HRM analysis in Isfahan province. BACKGROUND: Cystic echincoccosis, so-called hydatidosis, is widespread infection caused by the larval stage of Echinococcus granulosus. This is an important zoonotic disease worldwide, especially in the developing countries such as Iran. To date, molecular studies mainly based on the mitochondrial DNA sequences have identified distinct genotypes termed G1-G10 which can differ in some characteristics such as the growth and infectivity to different intermediate hosts or the survival rate in the definitive hosts that are important for the development of control strategies...
