Reza Ansari, Omid Ghanaei, Sahand Sohrabi, Hiva Amjadi, Homaun Vahedi, Shahin Merat, Seydmohammadmahdi Mirnasseri Page 7

Background
Functional constipation (FC) and constipation-predominant irritable bowl syndrome (CIBS)are two main subtypes of constipation that can be distinguished by the Rome II criteria. Measuring colonic transit time (CTT) is an easy and cost effective way to evaluate constipation. This study was conducted to compare the CTT in patients with FC and CIBS.
Materials And Methods
Those patients who referred to our hospital with complaint of chronic constipation were studied and those with no organic disease were included in this study. Using the Rome II criteria, they were then categorized as having FC or C-IBS. All patients ingested 10 radioopaque markers daily for six days. A plain abdominal x-ray was taken on the seventh day. Markers in the right and left hemicolon and rectosigmoid were counted and the total and segmental transit times were calculated and reported in hours.
Results
A total of 45 patients with FC and 45 with C-IBS were enrolled into this study. The total CTT was normal in 42% of those with FC and in 55% of those with C-IBS. The mean total CTT was not significantly different between the two studied groups. Nonetheless, the mean rectosigmoid transit time of patients with FC was significantly higher than those with C-IBS (p=0.008). There was no significant difference between the right and left hemicolon transit time.
Conclusions
Although the CTT of patients with FC might be higher than those with C-IBS, it seems that applying the Rome II criteria to distinguish these two groups does not affect the selection of treatment strategy.

Mahin Roozitalab, Marzieh Moatari, Sakineh Gholamzadeh, Mehdi Saberifiroozi, Najaf Zare Page 19

Background
Success of screening programs depends on the people belief toward the importance and necessityof these programs. This study was conducted to determine the effect of health belief on participation of official administrative personnel of Shiraz University of Medical Sciences with an average risk (age: 40 years) for colorectal cancer in fecal occult blood test (FOBT).
Materials And Methods
In this sub experimental study 156 subjects were selected using a random cluster sampling and divided randomly into two grous of experimental and control (n=78 for each). In the first stage, the level of knowledge, status of willingness and barriers related to participation in screening program were examined in each of two groups. The intervention program was done according to the health belief model for the experimental group. then, 3 stool samples in different times for checking occult blood were collected from the subjects who attended the laboratory. The results were then reported to them. The level of awareness was re-examined by a questionnaire after 3 months. Comparison of level of knowledge and participation before and after intervention was implemented.
Results
In the two groups studied, only 19 subject (12%) believed in screening programs. Lack of time in 53 subjects (58%) and lack of awareness in 49 (53%) were the most common barriersfor participation in screening programs (FOBT). In each of two groups, 8 subjects (5/2%) were aware of CRC and screening programs. The mean level of awareness changed from1/192 in the first stage of the study to 11/166(P

Esophageal Cancer in Iran A Review

Reza Malekzadeh, Shahryar Semnani, Alireza Sadjadi Page 25

Esophageal cancer is the second most common malignancy in Iranian men; it is the third in women. It is killing about 5800 Iranians each year. Squamous cell carcinoma (SCC) is presently the most common type of esophageal cancer accounting for about 90% of all esophageal cancers in Iran. Recent studies in Iran have shown that there is a gradual increase in the incidence of adenocarcinoma of the distal esophagus along with gastric cardia adenocarcinoma. Thirty-five years ago, the age-adjusted incidence rate (ASR) of SCC of esophagus in Gonbad city, Golestan province, Northeast of Iran (›100 per 105 people per year), was found to be one of the highest rates for any single cancer ever reported in the world. Recent studies have shown that the incidence of SCC in Gonbad has declined to less than half of what it was in the past. This decline in the incidence of esophageal SCC is in parallel with improvement in socioeconomic status of people living in this region. According to the recent cancer registry data in Iran, there is still an obvious intra-country variability between the incidence of esophageal cancer in South with an ASR of 3 for men and 2 for women in Kerman and 43 and 36, respectively, in northeastern province of Golestan. The reasons for this very high rate of SCC in northeastern Iran has been the subject of several studies during the last 35 years. According to the results of these studies, the suspected risk factors include low intake of fruits and vegetables, drinking hot tea, consumption of opium products and tobacco, H.pylori infection in stomach, using unhealthy drinking water from cistern and genetic susceptibility. The main suspected mutagens are polycyclic aromatic hydrocarbons (PAH) and N-Nitroso compounds. In order to embark on a primary and secondary prevention of this fatal cancer further prospective studies are presently going on in the northeastern Iran.Golestan cohort study of esophageal cancer with enrollment of 50,000 subjects is now in its follow-up phase. We expect simple and feasible evidence based preventive strategies to be implemented in future from the results of these studies.

Background
Inflammatory bowel disease (IBD) may begin as early as the first year of life. The objective of the present study was to determine the characteristics and clinical course of children with early-onset IBD.
Materials And Methods
The records of patients with IBD admitted to Children Medical Center Hospital during 2003-2006 were screened for those with disease onset before the first year of life and who had a follow-up of at least 2 years.
Results
12 patients (8 boys, 4 girls) were identified. 9 had Crohn's disease. All of the patients had colitis. One of parents had IBD in 9 patients; 2 had a positive family history for IBD. 7 patientshad weaned of breast fed when the gastrointestinal symptoms started. 10 patients had a severe onset of disease requiring total parenteral nutrition, and steroid followed by azathioprine. 3 patients with Crohn's disease needed surgery; another 3 with Crohn's disease died during the study. Of those with ulcerative colitis, one is in complete remission.
Conclusions
The prevalence of inflammatory bowel disease in infancy is unknown, but appears to be increasing. The course of the disease seems more severe.

COLONOSCOPIC FINDINGS IN CHILDREN WITH LOWER GASTROINTESTINAL BLEEDING

Farzaneh Motamed, Mehri Najafisani, Ahmad Khodadad, Gholamhossein Fallahi, Fatemeh Farahmand, Mohammad Sobhani Page 54

Background
Lower gastrointestinal bleeding (LGIB) in children has many different etiologies and is a serious problem that warrants careful diagnostic work-up.
Materials And Methods
164 colonoscopies were done during one year for determining the etiologies of LGIB in children who was referred to Children's Medical Center Hospital. Analyses of results were based on age, sex, etiology and clinical presentations.
Results
of 164 colonoscopies, 34.7% of LGBI were due to polyps which was the most common etiology. Lymphoid nodular hyperplasia (LNH) had a prevalence of 22.5%; in 15.8% of patients, colonoscopic findings were normal. The peak age group of polyps was 4-6 yr; for LNH, it was 1 yr.
Conclusions
LNH is more common than polyps in patients presenting with LGIB younger than 3 yrs. In older children, however, polyps are the major cause. Therefore, the diagnostic approach and the need for colonoscopy are different in these two age groups.
