Intraductal papillary mucinous neoplasms (IPMNs) are rare pancreatic tumours, accounting for less of 1-2% of all neoplasms of the gland. Main characteristics of IPMNs are their favourable prognosis as these pre-malignant or frankly malignant lesions are usually slow-growing tumours and radical surgery is frequently possible. According with the localization of the lesions, three different entities are identified: the main-duct IPMN (type I), the branch-duct IPMN (type II) and the mixed type (type III, involving both the main pancreatic duct and side branches). IMPNs do not present pathognomonic signs or symptoms. Obstruction of the main pancreatic duct system may cause abdominal pain and acute pancreatitis (single or recurrent episodes). The tumour may be incidentally discovered in asymptomatic patients, particularly in those with branch-duct IPMNs. In clinical practice, any non-inflammatory cystic lesion of the pancreas should be considered as possible IPMN. Computed tomography, magnetic resonance imaging with cholangiopancreatography and endoscopic ultrasonography can localize IPMN and assess its morphology and size. The choice between non-operative and surgical management strictly depends from the risk of malignancy and of the definitively distinction between benign and malignant IPMNs. Main-duct IPMNs are at higher risk of malignant degeneration, especially in older patients; as a consequence no doubt does not exist as concerns the need of surgery for IPMN type I and III. A less aggressive surgical approach as well as the possibility of conservative management have been suggested for asymptomatic, small size (< 3-3.5 cm), branch-duct IPMN.

Aim: In this paper effect of combinational usage of calprotectin and etoposide on AGS cell line is studied.

Background: Application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. As a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (AGS) as antitumor agents. Both calprotectin and etoposide are topo II inhibitor. Etoposide is a lipophilic agent that can easily transport from membrane while calprotectin active intracellular pathway, probably by membrane surface receptor.

Patients and methods: Calprotectin was purified from human neutrophil by chromatography methods. The human gastric adenocarcinoma cell line was exposed to different concentrations and combinations of calprotectin and etoposide. MTT assay was applied for evaluation of cytotoxicity assay.

Results: Viability of AGS cell line was reduced in high dosages of calprotectin and etposide. In fact, overnight incubation of these two agents together has been shown less effective than individual usage.

Conclusion: The result indicates that, the combination of both calprotectin and etoposide is considerably less cytotoxic on gastric cancer cells (AGS) than applying individually.

Aim: the objective of this study was to estimate the average cost of diagnosis and treatment of hepatitis C among patients based on their treatment regime, during the one course of treatment and six-month after stopping that.

Background: Hepatitis C virus (HCV) infection is a major cause of liver-related morbidity and mortality worldwide and a major public health problem.

Patients and methods: All data for this cross-sectional study were collected from medical records of 200 patients with hepatitis C, who referred to a private gastroenterology clinic between years 2005 through 2009. Information related to the 200 patients was extracted from their medical records and finally, 77 patients of them, who their treatment was not interfering with any other disease entered in this study. Therefore diagnosis and treatment costs of these patients were calculated. Attributable costs were reported as purchasing power parity dollars (PPP$).

Results: Mean costs of diagnosis and treatment in one course of treatment and six month after that with standard interferon plus ribavirin (INF-RBV) exceeds 3,850 PPP$ and for patients who treated with peg-interferon plus ribavirin (PEG-RIBV) was 16,494 PPP$. Also in both types of treatment, medication cost was found to be a dominant cost component.

Conclusion: Hepatitis C represents a very important and potentially costly disease to managed care organizations. Patients with this disease require expensive drug therapies and consume significant health care resources.

Aim: To assess the clinical characteristic of CD as well as correlation of symptoms and the degrees of intestinal mucosal lesions in Iranian children.

Background: Microscopic Enteritis (Marsh 0-II) is associated with malabsorption.

Patients and methods: From August 2005 to September 2009, 111 cases with malabsorption and classical gastrointestinal symptoms were evaluated.

Results: The mean (±SD) age of children with CD was 4.9±3.5 years (range, 6 month - 16 years) and the mean duration of symptoms was 8 ± 20.5 months. 50 cases (45%) were female and 61 cases (55%) were male. The most common clinical presentation was failure to thrive in 72%, chronic diarrhea in 65.8% and Iron deficiency anemia in 59.5%. Sensitivity of EMA was 100% in patients with Marsh IIIb and Marsh IIIc. EMA was also positive in 77% of cases with Marsh 0, 18% in Marsh I, 44% in Marsh II and 81.8% in patients with Marsh IIIa.

Conclusion: Histopathology did not reflect the severity of gluten sensitivity. This would suggest that the degree of intestinal mucosal damage might not be a reliable prognostic factor. Significant symptoms can be present with minor histological change on biopsy.

Aim: The study aims to document the oral lesions in patients with UC.

Background: Inflammatory bowel disease (IBD) is comprised of two chronic, tissue-destructive and clinical entities including Crohn's disease (CD) and ulcerative colitis (UC), both of which are immunologically based.

Patients and methods: The population of the study includes fifty patients with UC, as the experimental group, and fifty patients without gastrointestinal disease as the control group. All patients had an oral examination and completed the relevant questionnaire.

Results: There was a significant statistical relationship among tongue coating (<0.0001), halitosis (<0.0001), and oral ulceration (0.001) in patients suffering from severe UC compared to the control group. Also there was a higher prevalence of oral manifestations in patients with moderate UC compared to that of control group; but taste change (0.001) was the only significant factor. Acidic taste and taste change were among the symptoms more commonly found in patients suffering from pancolitis (40% each).

Conclusion: The results of the present study show that patients with UC had more oral signs and symptoms than the patients in the normal group.  Further researches on oral lesions in UC are also recommended so that these diseases can be better understood.

Aim: This study was designed to evaluate the frequency of antibody against these viruses in individuals attending the endoscopy ward of Taleghani hospital Tehran, Iran.

Background: Blood-borne viruses such as hepatitis B and hepatitis C virus and HTLV-1 virus are among the world’s public health problems. Hepatitis viruses cause liver problems and HTLV-1 infection can lead to adult T-Cell lymphoma (ATL).

Patients and methods: Blood samples of 219 individuals attending the endoscopy ward of Taleghani hospital between years 2009-2011 were collected. A questionnaire containing demographic data was completed for each subject. Blood samples were tested for antibody against HTLV-1, HCV and HBc by ELISA (Dia.pro Italy). In case of positive results for anti-HBc, samples were also tested for HBs Ag antigen.

Results: Ninety two subjects were male and 127 were female. Mean age of the population was 39.87 ± 16.47. None of the subjects had anti-HCV antibody, while 4 of them had anti-HTLV-1 antibody and 26 anti-HBc antibody; which only two of these individuals had HBs Antibody.

Conclusion: The results of this study show that frequency of anti-HCV and anti-HTLV-1 antibodies are very low, while the frequency of anti-HBc was higher in the population. Since HTLV-1 is the causative agent of a type of blood cancer, it seems that screening of donated bloods in this region should be considered.

Hepatitis B, as a chronic disorder that may be associated with several psychiatric disorders, such as depression, and decrease quality of life of affected patients. One of the most important consequences of psychiatric problems is reduced patient compliance with prolonged therapeutic regimens. Psychotherapy, such as solution– focused therapy, may help these patients to resolve psychiatric problems, increase quality of life and completion of therapeutic regimens. Solution-focused therapy is effective for patients when developing effective coping responses to the stressors associated with chronic diseases. In this study, the process and effects of solution-focused therapy on depression of 2 patients with chronic hepatitis B have been described. They received solution focused therapy for 5 sessions, each session 1 hour once a week. This technique was helpful to decrease symptoms and signs of depression within 5 weeks.
