Abstract
Background: Functional constipation and gastroesophageal reflux disease (GERD) are two common childhood digestive disorders which can cause a lot of complications among them if untreated. Since an overlap and relationship between functional gastrointestinal disorders have been shown in some studies, so present study was performed to investigate the frequency of functional constipation among children with reflux in compare with children without reflux.
Methods: A cross-sectional study was conducted on all children who referred to digestive diseases clinic of Ali-Asghar Hospital in Tehran, Iran, from April 2008 to January 2010. Patients that referred for follow up were excluded from study and a total of 474 children were included in this study. A questionnaire including symptoms of reflux and functional constipation was completed for all subjects by design’s executer after parental consent. Other data related to history, physical examination and results of paraclinic investigations for functional constipation diagnosis were also collected.
Results: In general 247 children (52%) were male and 227 children (48%) were female. Nineteen children (4%) had gastroesophageal reflux disease in this study which 6 of them (31.5%) were less than 1 year old and 13 of them (68.5%) were greater than 1 year old. Opisthotonic posturing, abdominal pain, heartburn and recurrent vomiting were the most common symptoms in children with reflux. There was also functional constipation in 60 children. Twelve patients (63.2%) had functional constipation among 19 children with reflux, whereas 48 patients (10.5%) had functional constipation among 455 children without reflux. This different frequency ranges of functional constipation among children with and without gastroesophageal reflux was statistically significant (P= 0.001).
Conclusion: The frequency of functional constipation in children with gastroesophageal reflux was significantly more than normal children. Further studies are recommended to investigate the relationship between functional constipation and gastroesophageal reflux in children.

Abstract
Background: Among all types of cancers, pancreatic cancer has poor prognosis with 5-year survival below 10%. In theory, alcohol intake may be a modifiable risk factor for pancreatic cancer due to its role in multiple carcinogenic and metabolic signaling pathways. In addition, alcohol consumption may lead to chronic pancreatitis which is underlying cause of pancreatic cancer. However, little is known about whether this factor is associated with pancreatic cancer. This study aimed to systematically review the cohort studies investigating the possible link between alcohol consumption and the morbidity or mortality of pancreatic cancer.
Methods: This study was carried out based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). All of cohort studies that assessed the association between alcohol intake and the risk of pancreatic cancer or death were included in this systematic review without a language restriction. Electronic databases including PubMed, Web of science, Scopus, and Google scholar were searched using the keywords "pancreatic cancer" and "alcohol" and similar words from 1990 to April 2021 to find the cohort studies.
Results: 858 articles were identified, of which 806 were excluded and the full-text of 52 papers were evaluated for the eligibility. Eventually, 22 articles were eligible and were included in this study. Many of the articles assessed the impacts of low to moderate alcohol intake. A comprehensive review of these studies showed that low to moderate alcohol consumption had a non-significant correlation with pancreatic cancer, while high alcohol consumption was significantly associated with the risk of pancreatic cancer or death. The results also revealed that high liquor consumption was associated with higher risk of pancreatic cancer. Nevertheless, the follow-up durations in most of these studies were shorter than that to lead to pancreatic cancer.
Conclusion: Long-term heavy alcohol drinking can increase the morbidity or mortality of pancreatic cancer. Regarding that several genetic and environmental variations involve in the pathogenesis of this cancer, simultaneous control of these differences should be addressed to determine the net effect of alcohol drinking on pancreatic cancer.
