Background: The goal of this study was to evaluate magnetic resonance enterography (MRE) findings and assess the role of diffusion-weighted imaging (DWI) in patients suffering from active Crohn's disease.

Methods: This retrospective study included a total number of 76 patients diagnosed with active Crohn's disease, as established by the Crohn's Disease Activity Index (CDAI). The study consisted of 30 women and 46 men, ranging in age from 13 to 72 years. All participants underwent MRE with DWI sequences. The study was conducted at Imam Khomeini hospital in Tehran between 2013 and 2018. The imaging modality utilized for the study included a 3-T SIGNA Excite MRE machine and a Siemens Magnetom 3-T magnetic resonance imaging (MRI) machine.

Results: Bowel wall restriction was observed in less than half of the patients, and no significant correlation was found with extramural findings such as mesenteric edema. The study did not reveal any meaningful association between diffusion restriction and specific mural enhancement patterns, mesenteric lymphadenopathy with or without enhancement, or the length of the affected segments (P>0.05). The most common findings observed in MRI were ileum thickness in 72.4% of patients, mesenteric lymphadenopathy without enhancement in 46.1%, ileocecal thickness in 42.1%, DWI findings in 42.1%, the presence of a comb sign in 36.8%, and jejunum thickness in 30.3% of patients.

Conclusion: MRE findings are useful in the evaluation of Crohn's disease activity.

Background: The aim of this research was to compare the effectiveness of mindfulness-based stress reduction and compassion-focused on the severity of digestive symptoms in patients with irritable bowel syndrome (IBS).

Methods: The research method was of semi-experimental type with pre-test, post-test, follow-up, and experimental and control groups. The population included patients with IBS in Isfahan city, 45 of them were selected by convenience sampling method and randomly assigned to three groups (15 in each group). Then, the patients of one experimental group received eight sessions of 90 minutes of a mindfulness-based stress reduction program, while the other experimental group received eight sessions of 90 minutes of compassion-focused therapy. The measurement tools included the severity of IBS scale and a short clinical interview. Research data were analyzed using variance analysis with repeated measures on one factor (mixed design).

Results: The results showed that both methods of intervention had been equally effective on the severity of disease symptoms (P<0.01).

Conclusion: Both intervention methods can be used as a complementary treatment for patients with IBS.

Background: In pediatrics, appendicitis is the leading cause of emergency surgery. It was previously believed that postponing the surgery could lead to the appendix rupture. Children with this condition can be difficult to diagnose. The evidence regarding the necessity of an immediate appendectomy is a topic of debate. In this study, we evaluated the medical records of patients who were diagnosed with acute appendicitis to determine whether postponing appendectomy for one night is safe or not.

Methods: This study involved 534 individuals diagnosed with acute appendicitis, who were separated into two groups: those who underwent an appendectomy immediately (within 8 hours) and those who had a delayed procedure (between 8-18 hours). We recorded and compared demographic data, symptoms, laboratory results, time of symptoms, hospitalization duration, surgery duration, overall time, length of stay after surgery, and any other complications that occurred between the two groups.

Results: The rate of surgical site infection (SSI) did not differ significantly between the groups (2.8% vs 4.2%, P=0.74). Additionally, there was no significant difference in the risk of perforation between the time of surgery in our study (21.9% vs 19.8%, P>0.05).

Conclusion: Our findings suggest that there is no increased risk of complications such as perforation when appendectomy is delayed for up to 18 hours.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic immune-mediated disease. The incidence of IBD is influenced by various genetic and environmental factors, with dietary habits gaining significant scientific interest. While the role of diet in the pathogenesis and development of IBD is still debated, recent studies have demonstrated its potential impact. However, conflicting findings exist regarding the efficacy of dietary interventions in the treatment and control of IBD. This review aimed to summarize the current understanding of the relationship between diet and IBD, highlighting the different perspectives and reasonings observed in recent studies. Overall, it has been shown that dietary habits play a role in the incidence of IBD, and adopting a controlled dietary approach may help manage the disease. Consequently, diet can be considered a predictive and prognostic factor in IBD.

This is not surprising to detect iron overload in chronic liver diseases and end-stage liver diseases since Kupffer cells scavenge necrotic hepatocytes during the course of liver damage, leading to an increased serum iron level and transferrin saturation compatible with iron overload even in the absence of a genetic mutation suggestive of hereditary hemochromatosis. Therewith, a relative association has been found between some sorts of chronic liver diseases like non-alcoholic steatohepatitis and hepatitis C with human homeostatic iron regulator protein (HFE: High Fe²⁺) gene mutations. Moreover, impairment of ceruloplasmin ferroxidase activity in the course of Wilson's disease (WD), leading to the accumulation of ferrous ions just like what is expected in aceruloplasminemia, is another known reason for iron overload accompanied by chronic liver disease. Of chronic liver diseases, autoimmune hepatitis (AIH), and cholestatic liver diseases are less related to iron overload. Accordingly, the coexistence of WD, AIH, and hereditary hemochromatosis when there exist clinical features, laboratory tests, genetic confirmation, and histological evaluations indicative of the three mentioned diseases is exceedingly rare. Here, we present a 55-year-old man referred with progressive generalized icterus accompanied by loss of appetite and significant weight loss. The presented case was not an appropriate candidate for liver biopsy due to recent coronary angioplasty and the urgent need for dual antiplatelet therapy. However, medical follow-ups were highly suggestive of concomitant WD, hereditary hemochromatosis, and AIH. The attempts failed for the treatment of hereditary hemochromatosis and WD with chelating agents until the completion of the course of treatment with immunosuppressants targeting components of the AIH-related immune system.

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in the world. Previous studies revealed that cholecystectomy may be considered a risk factor for the development of NAFLD. The aim of this study was to compare the amount of liver fibrosis, determined by elastography, between patients with NAFLD with and without a history of cholecystectomy.

Methods: In this descriptive-analytical cross-sectional study, 50 patients with NAFLD were divided into two groups: one with a history of cholecystectomy and the other without. No significant differences were found between these two groups in terms of age or sex distribution. Liver fibrosis was measured for all patients using an elastography imaging system. Subsequently, the data related to liver fibrosis, along with the demographic information of the patients, were statistically analyzed using SPSS software version 22.

Results: The mean elastography score in all patients was 10.66±12.18 kPa (the elasticity scale ranging from 3.80 to 66.40 kPa). The group with a history of cholecystectomy had a significantly higher mean elastography score (13.39±16.20 kPa) compared with the group without cholecystectomy (7.93±4.99 kPa) (P=0.02). Additionally, there was a significant positive correlation between body mass index (BMI) and the mean elastography score in the group of patients with a history of cholecystectomy.

Conclusion: The mean elastography score of patients with NAFLD with a history of cholecystectomy was approximately twice as high as that of non-cholecystectomy patients.

Background: We aim to present incidence rates and geographical distribution of most common early-onset gastrointestinal cancers (EOGICs), including early-onset esophageal cancer (EOEC), gastric cancer (EOGC) and colorectal cancer (EOCRC) in Iran, 2014-2018.

Methods: Data on new cases of EOEC, EOGC and EOCRC were obtained from publicly available annual reports of the Iranian National Population-based Cancer Registry (INPCR). Incidence rates were calculated using the population data available from the Statistical center of Iran. We considered the World standard population for calculation of age-standardized incidence rates (ASR). We also calculated 95% confidence intervals (CIs) for ASR. All rates are presented per 100000 person-years.

Results: Overall, 19,679 new cases of EOGIC were registered by the INPCR between 2014 and 2018. The ASRs (95% CI) of EOEC, EOGC and EOCRC were 0.49 (95% CI: 0.47-0.51), 1.67 (1.63-1.71), and 3.07 (3.01-3.13) per 100,000 person-years, respectively. Our findings indicate decreasing and constant trends in the ASR of EOEC and EOGC during the study period, 2014-2018. There was an increasing trend in the ASR of EOCRC. We also found geographical disparities in the incidence rates of EOGICs across provinces of Iran, suggesting the highest ASRs of EOEC in Golestan (1.3), EOGC in Ilam (2.99) and EOCRC in Ilam (4.49).

Conclusion: Our findings suggested that the incidence rate of EOCRC is consistently increasing. We also found variations in the incidence of EOGICs among different provinces. Further investigations are recommended to clarify the time trends and risk factors of EOGICs in Iran.

Background: Sleep quality is a notable factor of well-being. It also may play a role in the development and progression of chronic diseases and cancers. Therefore, this study was performed to investigate poor sleep quality and its influencing factors among Iranian patients with esophageal and gastric cancer.

Methods: In this cross-sectional study, a total of 312 Iranian adult patients who suffered from esophageal and gastric cancers were employed from a gastrointestinal cancer-based cohort study conducted in a referral hospital in Tehran between 2015 and 2018. Persian version of the Pittsburg Sleep Quality Index (PSQI) was used to measure poor sleep quality. Univariate and multiple logistic regression models were applied to determine the related factors to poor sleep quality.

Results: Of the participants, 203 (65.06%) were men, and 75.96% had gastric cancer. The mean age was 63.13±12.10 years. The results demonstrated that more than 62% of the patients had poor sleep quality. 148 (62.44%) patients out of 237 patients with gastric cancer had poor-quality sleep. Also, 46 (64.38%) patients out of 237 patients with esophageal cancer had poor-quality sleep. Based on the results of multiple logistic regression models, marital status has a negative association with poor sleep quality (odds ratio [OR]=0.32, P=0.015). In addition, having chronic disease (OR=2.16; P=0.028) and wealth index (OR=3.11, P=0.013; OR=3.81, P=0.003; OR=3.29, P=0.009; OR=3.85, P=0.003 for rich, moderate, poor, and poorest subgroups, respectively) had a positive association with poor sleep quality.

Conclusion: The findings showed that about two-thirds of the patients studied were poor sleepers. Also, it was observed that marital status, chronic disease, and wealth index were important factors associated with poor sleep quality.

Systemic lupus erythematosus (SLE) is a multi-systemic disorder affecting almost all systems of the body. Involvement of the kidney in this condition is known as lupus nephritis (LN). LN is one of the important disease manifestations of SLE with considerable influence on patient outcomes in terms of morbidity and mortality. A 33-year-old female came to the OPD with complaints of abdominal pain, infrequent loose stools since 4 months. The patient also had joint pain, predominantly small joints, since 2 months. Patient was admitted and all routine investigations were done. Patient underwent an oesophagogastroduodenoscopy (OGD) and colonoscopy for her abdominal pain and loose stools which did not respond to routine medication. Grossly there was edema present in the oesophagus and colon which on microscopy showed eosinophilic infiltration. Urine routine of the patient showed protein 1+and 24-hour urine protein quantification of 1427 mg/24 h. On further evaluation patient was found to have a positive ANA blot (dsDNA, AMAM2, Ro52 and Sm). The patient was planned for a renal biopsy in view of the proteinuria and positive ANA blot. The patient underwent a renal biopsy under USG guidance and was found to have Lupus nephritis Class 3 (ISN RPS staging). SLE is a multi-organ involving disease which if not diagnosed at the earliest can have serious complications and lead to end stage organ failure and even death. Atypical presentations often pose a diagnostic dilemma and may delay diagnosis and treatment. Early diagnosis and treatment can give patients of SLE a long and normal life. Diagnostic guidelines have helped in the diagnosis of such atypical presentations.

Background: Gluten sensitivity (GS) is one of the gluten-related disorders (GRDs). Patients with GS may have serum antibodies against tissue transglutaminase (tTG) (IgA and IgG) without any evidence of enteropathy. We aimed to evaluate both tTG-6 and tTG-2 antibodies to determine the prevalence of seropositive tTG-2 and tTG-6 antibodies in patients with multiple sclerosis (MS).

Methods: In this cross-sectional study, we carried out serological tests (IgA & IgG anti-tTG-6 and tTG-2 antibodies) in patients with MS.

Results: Seventy-two patients with MS were included in this study. Of them, seropositive patients for total (IgA+IgG) of tTG-6 and tTG-2 autoantibodies were 9.7% (95% CI, 4.2-18) and 5.6% (95% CI, 1.4-12.5), respectively.

Conclusion: Anti-tTG-6 antibody testing may be necessary for early diagnosis of GS in patients with MS. More studies with larger sample sizes are warranted to confirm these data.
