Factors affecting the use of herbal products in patients with Irritable Bowel Syndrome and their results: case-control study.

BACKGROUND: Irritable bowel syndrome (IBS) is a functional bowel disease that is characterized by abdominal pain, discomfort, and changes in the frequency and form of stool without any organic pathology. In this study, the factors that affect the herbal treatment choices of IBS patients and their results were investigated. METHODS: Included in the study were 248 IBS patients who were over the age of 18. A questionnaire that comprised 25 questions was applied to the participants. Survey questions were asked to the participants regarding their age, place of birth, gender, educational status, demographic details, social standing, socioeconomic status and job, place of residence, and marital status. In addition, The participants were asked about which IBS symptoms they had, from whom they had received the recommendation for use of herbal products, whether the media had an effect on their selection of herbal products, and whether they had benefited from herbal products. RESULTS: It was observed that 41.1% of the patients with IBS who participated in the study used herbal medicine, 9.8% of whom used them regularly. It was found that the IBS patients participating in the study made their decision to use herbal products mostly based on the recommendations that they were given by acquaintances (57%) and the media (34%). When the patients were evaluated according to their gender, IBS was found to be more common in unemployed women who had a low level of education, while it was more common in working men (p = 0.015, P < 0.001, respectively). The IBS patients who were single used more herbal products that those who were married (P = 0.036). While the use of herbal herbs and oils was predominant in patients whose recommendation content comprised the media/internet and acquaintances, the herbal treatment content recommended by healthcare professionals consisted of traditional treatments and mixtures (P = 0.012). It was determined that a higher percentage of those who used herbal treatments lived in city centers when compared to those who did not (P < 0.001). In addition, it was determined that patients with constipation used herbal products more than those without (P < 0.001). Among the IBS patients, those who had diarrhea and those who were receiving medical treatment preferred to use significantly less herbal products (P = 0.007 and P = 0.041, respectively). It was found that the patients who visited the Gastroenterology Outpatient Clinic mostly used herbal therapy, while those who visited a family doctor used herbal therapy the least (P = 0.029 and P < 0.001, respectively). CONCLUSION: The IBS patients revealed whose recommendations they followed when purchasing herbal products, which of the products they preferred, and how useful/beneficial they felt that these products were. In this regard, the addition of training curricula related to herbal treatment for professional healthcare workers will further raise awareness on this topic.

Thermoplastic elastomers containing antimicrobial and antiviral additives for mobility applications.

The transmission of the SARS-CoV-2 coronavirus has been shown through droplets generated by infected people when coughing, sneezing, or talking in close contact. These droplets either reach the next person directly or land on nearby surfaces. The objective of this study is to develop a novel, durable, and effective disinfecting antimicrobial (antiviral, antibacterial, and antifungal) styrene-ethylene/butylene-styrene (SEBS) based thermoplastic elastomers (TPE). TPE incorporated with six different formulations was investigated for mechanical and antiviral performance. The formulations consist of a combination of zinc pyrithione (ZnPT), sodium pentaborate pentahydrate (NaB), disodium octaborate tetrahydrate (DOT), and chlorhexidine (CHX). ZnPT and DOT incorporated TPE showed a reduction of microbes such as bacteria by up to 99.99%, deactivated Adenovirus, Poliovirus, Norovirus, and reduced a strain of the coronavirus family by 99.95% in 60 min on TPE samples. Control samples had higher tensile strengths among all formulations and tensile strength decreased by around 14%, 21% and 27% for ZnPT and DOT combinations compared to control samples. The elongation at break decreased by around 7%, 9% and 12% with ZnPT and DOT combinations, where it reached minimum values of 720%, 702% and 684%, respectively. The 100% Modulus and 300% Modulus slightly increased with ZnPT and NaB combination (reaching values from 1.6 to 1.9 MPa and 2.6-2.9 MPa respectively) in comparison with control samples. The MFI also decreased with antimicrobial and antiviral additives (decreasing values from 64.8 to 43.3 g/10 min). ZnPT and NaB combination showed the lowest MFI (43.3 g/10 min) and reduced the MFI of control sample by around 33%. TPE samples containing ZnPT and DOT combination showed biocidal activity against the microorganisms tested and can be used to develop antimicrobial products for multiple touchpoints within a vehicle and micro-mobility.

Spectroscopic super-resolution fluorescence cell imaging using ultra-small Ge quantum dots.

We demonstrate a spectroscopic imaging based super-resolution approach by separating the overlapping diffraction spots into several detectors during a single scanning period and taking advantage of the size-dependent emission wavelength in nanoparticles. This approach has been tested using off-the-shelf quantum dots (Invitrogen Qdot) and in-house novel ultra-small (~3 nm) Ge QDs. Furthermore, we developed a method-specific Gaussian fitting and maximum likelihood estimation based on a Matlab algorithm for fast QD localisation. This methodology results in a three-fold improvement in the number of localised QDs compared to non-spectroscopic images. With the addition of advanced ultra-small Ge probes, the number can be improved even further, giving at least 1.5 times improvement when compared to Qdots. Using a standard scanning confocal microscope we achieved a data acquisition rate of 200 ms per image frame. This is an improvement on single molecule localisation super-resolution microscopy where repeated image capture limits the imaging speed, and the size of fluorescence probes limits the possible theoretical localisation resolution. We show that our spectral deconvolution approach has a potential to deliver data acquisition rates on the ms scale thus providing super-resolution in live systems.

Role of baseline adenoma characteristics for adenoma recurrencein patients with high-risk adenoma

Background/aim: The present observational study aimed to determine the predictive value of 3-year recurrence adenoma characteristics at baseline conventional colonoscopy in patients with high-risk adenoma.Materials and methods: A total of 47 patients with high-risk adenoma at baseline colonoscopy were followed up and underwent a surveillance colonoscopy at 3 years. Correlations between adenoma recurrence and baseline adenoma characteristics (size, number, histological features, and location) were analyzed.Results: Among 135 patients with high-risk adenoma, 47 patients (35%) who underwent surveillance colonoscopy at 3 years following baseline colonoscopy were included in the study. In these 47 patients, at least one new adenoma was detected in 19 (40.4%) patients, and new advanced adenomas were detected in 5 (10.6%) patients during the surveillance colonoscopy. No significant difference was found in patients who had adenoma recurrence versus those who did not in terms of size of adenomas (P = 0.143), number of adenomas (P = 0.562), histological properties of adenomas (P = 0.658), or locations of adenomas (P = 0.567).Conclusion: Baseline adenoma characteristics were not associated with the recurrence of adenomas or advanced adenomas in patients with high-risk adenoma.

Local structure of Ge quantum dots determined by combined numerical analysis of EXAFS and XANES data.

The sensitivity of X-ray absorption near-edge structure (XANES) to the local symmetry has been investigated in small (∼4 nm) matrix-free Ge quantum dots. The FDMNES package was used to calculate the theoretical XANES spectra that were compared with the experimental data of as-prepared and annealed nanoparticles. It was found that XANES data for an as-prepared sample can only be adequately described if the second coordination shell of the diamond-type structural model is included in the FDMNES calculations. This is in contrast to the extended X-ray absorption fine-structure data that show only the first-shell signal. These results suggest that, despite the high degree of disorder and a large surface-to-volume ratio, as-prepared small Ge quantum dots retain the diamond-type symmetry beyond the first shell. Furthermore, we utilized this sensitivity of XANES to the local symmetry to study annealed Ge quantum dots and found evidence for significant structural distortion which we attribute to the existence of surface disorder in the annealed oxygen-free Ge quantum dots.

Pressure-Induced Amorphization and a New High Density Amorphous Metallic Phase in Matrix-Free Ge Nanoparticles.

Over the last two decades, it has been demonstrated that size effects have significant consequences for the atomic arrangements and phase behavior of matter under extreme pressure. Furthermore, it has been shown that an understanding of how size affects critical pressure-temperature conditions provides vital guidance in the search for materials with novel properties. Here, we report on the remarkable behavior of small (under ~5 nm) matrix-free Ge nanoparticles under hydrostatic compression that is drastically different from both larger nanoparticles and bulk Ge. We discover that the application of pressure drives surface-induced amorphization leading to Ge-Ge bond overcompression and eventually to a polyamorphic semiconductor-to-metal transformation. A combination of spectroscopic techniques together with ab initio simulations were employed to reveal the details of the transformation mechanism into a new high density phase-amorphous metallic Ge.

Structure and effects of annealing in colloidal matrix-free Ge quantum dots.

The structure of small (2-5 nm) Ge quantum dots prepared by the colloidal synthesis route is examined. Samples were synthesized using either GeO2 or GeCl4 as precursor. As-prepared samples were further annealed under Ar or H2/Ar atmosphere at different temperatures in order to understand the effect of annealing on their structure. It was found that as-prepared samples possess distinctly different structures depending on their synthesis route as indicated by their long-range ordering. An appreciable amount of oxygen was found to be bound to Ge in samples prepared with GeO2 as a precursor; however, not for GeCl4. Based on combined transmission electron microscope, Raman, X-ray diffraction and X-ray absorption measurements, it is suggested that as-prepared samples are best described by the core-shell model with a small nano-crystalline core and an amorphous outer layer terminated either with oxygen or hydrogen depending on the synthesis route. Annealing in an H2Ar atmosphere leads to sample crystallization and further nanoparticle growth, while at the same time reducing the Ge-O bonding. X-ray diffraction measurements for as-prepared and annealed samples indicate that diamond-type and metastable phases are present.

Risk Factors for Polyautoimmunity among Patients with Celiac Disease: A Cross-Sectional Survey.

AIM: To define the prevalence of polyautoimmunity (PAI) among celiac disease (CD) patients and to compare clinical and laboratory features of CD patients with or without PAI in order to determine the risk factors for PAI in CD. MATERIAL AND METHOD: Patients diagnosed with CD in our clinic between 2007 and 2014 with at least 1 year of follow-up were retrospectively evaluated. Totally 145 patients were included in the study. Information on patient demographics and laboratory data were obtained from patient records. The study participants were divided into 2 groups. Group 1 was the CD-alone group consisting of patients without any other autoimmune diseases (AIDs), while group 2 was the PAI group consisting of patients with accompanying one or more AIDs. RESULTS: The mean age of 145 CD patients (106 female and 39 male) included in the study was 37.2 ± 12.3 years. Of the 145 patients included, 48 (33.1%) were in the PAI group. When two groups were compared with each other in terms of the demographic features and laboratory data, the following were identified as risk factors for PAI: female gender, family history for AIDs, antigliadin IgG positivity, vitamin D deficiency, antinuclear antibody positivity ≥1/80 titer and having any musculoskeletal disease. CONCLUSION: To the best of our knowledge, this is one of the largest studies in the literature on CD patients for the PAI prevalence and related risk factors. Identification of the risk factors in early stages is important to explore PAI among CD patients. Larger, prospective studies are warranted about the risk factors and autoimmune characteristics of CD.

Adverse Events in Endoscopic Retrograde Cholangiopancreticography for Choledocholithiasis: A Holistic Perspective.

Background and aims In this study, we aimed to investigate the frequency of adverse events (AEs) in patients undergoing endoscopic retrograde cholangiopancreticography (ERCP) for choledocholithiasis and the independent risk factors that may cause these conditions. We planned to evaluate all AEs including cardiopulmonary complications and the risk factors that may affect them holistically. Methods This study was designed as a retrospective cohort study conducted at a single tertiary center's gastroenterology clinic. The study included patients with naive papillae and undergoing ERCP for choledocholithiasis between May 2019 and June 2022. Risk factors that may lead to AEs were analyzed in terms of both patient-related factors and procedure-related factors. Patients with and without AEs after ERCP were compared. Results This study included 812 patients who underwent ERCP for choledocholithiasis. AE occurred in 149 (18.3%) of patients, and the most common complication was pancreatitis (n=112, 13.8%). In regression analysis, of the patient- and procedure-related factors, only difficult cannulation was a significant independent risk factor for AEs (odds ratio=3.85, 95% CI: 1.102-13.498, p=0.035). Conclusion This study showed that, of patient- and procedure-related factors, only difficult cannulation is an independent risk factor for ERCP-related AEs.

Assessment of The Factors Related to The Spontaneous Passage of Common Bile Duct Stones.

Background: Common bile duct (CBD) stones may pass spontaneously without any intervention. Assessment of the predictors of spontaneous passage can contribute to avoiding unnecessary endoscopic retrograde cholangiopancreatography (ERCP) implementation. This study aimed to investigate the factors related to spontaneous passage of CBD stones. Methods: From January 2021 to August 2023, patients with naïve papilla who had undergone biliary ERCP and with CBD stones detected by MRCP before the procedure were analyzed retrospectively. Subjects were divided into two groups on the basis of the presence of stones during the ERCP procedure: the spontaneous passage group and the non-passage group. Groups were compared in terms of demographic, laboratory, and radiological data. Results: A total of 236 patients, including 26 in the spontaneous passage group and 210 in the non-passage group, were involved. Multivariate logistic regression analyses revealed that only stone size was significantly associated with spontaneous passage. From ROC curve analysis, stone size with a cut-off value of 4.3 mm predicted spontaneous passage with 58% sensitivity and 85% specificity. Conclusions: Stones with a size of less than 4.3 mm are more likely to pass spontaneously without endoscopic intervention. Paying attention to the stone diameter before ERCP procedures can contribute to avoiding unnecessary ERCP implementation.

Acute pancreatitis caused by bortezomib.

Drug-induced pancreatitis has been reported rarely. Bortezomib is a selective and reversible proteasome inhibitor used for the treatment of patients with multiple myeloma (MM). Recently, one case report about acute pancreatitis (AP) caused by bortezomib was published in the international literature. Herein we report a case of AP in a 67-year-old male on bortezomib therapy. On the fourth day after the first administration of bortezomib, the patient admitted to the hospital with symptoms of AP. The common etiological factors for AP were all excluded. Than the patient was diagnosed as bortezomib-induced pancreatitis.

A novel biphasic oral contrast solution for enterographic studies.

PURPOSE: To compare the efficacy and patients' tolerance of a new mixed biphasic oral contrast solution with routine biphasic oral contrast agent in magnetic resonance (MR) enterography (MRE). MATERIALS AND METHODS: Thirty-seven patients (group 1) had MRE with the new mixture, whereas 14 patients (group 2) had MRE with biphasic oral contrast agent (lactulose). Magnetic resonance enterography images were evaluated by 2 experienced radiologists. Each intestinal segment was evaluated for luminal distension (LD), distinction from the surrounding tissue (wall conspicuity), and the confidence of radiologist for evaluation of the specified segment (radiological evaluation confidence). Comparisons between the 2 groups were performed using the Mann-Whitney U test. Interrater and intrarater agreement values were obtained. In addition, patients' acceptability and tolerance were assessed. RESULTS: The new mixture was more effective than the oral contrast agent used in group 2 for LD, wall conspicuity, and radiological confidence. The values of interrater and intrarater agreement in scoring LD, wall conspicuity, and radiological confidence were generally moderate. CONCLUSION: Our new mixture allowed good-quality enterographic images, and this solution was well tolerated by patients. In addition, this mixture is useful for evaluation of small bowels and colonic segments. We suggest the use of it for enterographic examinations.

Small Bowel Video Capsule Endoscopy Guidance in Practice: Expert Opinion Report.

Capsule endoscopy, in clinical use since the 2000s, has disrupted the diagnosis of various small bowel diseases, especially obscuregastrointestinal bleeding. An overview of information on indications, contraindications, patient management, and patient preparationfor capsule endoscopy, which allows the evaluation of the entire gastrointestinal tract, will be helpful for both referrers and capsuleendoscopy. This review critically considers current evidence on the optimal clinical use of capsule endoscopy and addresses areas in the "gray zone."

The evaluation of endothelial functions in patients with celiac disease.

AIM: Celiac disease is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine after the ingestion of wheat gluten or related rye and barley proteins. This study aimed to identify individuals who are at risk of heart failure and increased risk for cardiovascular events by evaluating endothelial function in patients with celiac disease. MATERIALS AND METHODS: The study included 36 patients with celiac disease and 35 healthy volunteers. After all routine laboratory examination, left ventricular functions were evaluated with standard two-dimensional, M-mode conventional Doppler methods. Then, flow-mediated dilatation and nitroglycerin-dependent dilatation tests on brachial artery were performed to all patients and controls. RESULTS: A total of 36 celiac patients and 35 healthy volunteers were included in the study. The brachial artery diameter at baseline was similar between both groups. Measured brachial artery diameter after hyperemia was 30.19 ± 4.47 mm in celiac patients and 32.35 ± 3.77 mm in the control group. Differences between two groups were statistically significant (P = 0.031). Flow-mediated vasodilatation was lower in celiac patients compared with in controls (10.61 ± 2.64% vs 13.09 ± 2.9%; P = 0.0003). Measured endothelium-independent vasodilatation in the brachial artery before and after nitroglycerin was similar between both groups (P = 0.09 and P = 0.07, respectively). CONCLUSION: This research which aimed to evaluate endothelial dysfunction in patients with celiac disease is the first in the literature. As a result of this study, we found endothelial dysfunction at the macrovascular level in celiac patients.

An Evaluation of Thiol/Disulphide Homeostasis and HDL Values in Patients with Cholelithiasis: A Prospective Case-control Study.

OBJECTIVE: To determine the changes in thiol/disulphide homeostasis in patients determined with asymptomatic cholelithiasis and to investigate any potential correlation between these thiol-disulphide parameters and HDL cholesterol. STUDY DESIGN: A descriptive, comparative study. PLACE AND DURATION OF STUDY: Ankara City Hospital between 15 September and 31 December 2019. METHODOLOGY: This study included 42 patients aged 18-70 years, who presented at the Gastroenterology Clinic and were diagnosed with cholelithiasis on ultrasound examination. A control group was formed of 51 healthy volunteers aged 18-70 years. Thiol/disulphide homeostasis and HDL cholesterol was noted and compared between the groups. RESULTS: The mean age was 44.16 ± 13.35 years in cholelithiasis patient group and 31.88±13.27 years in the control group. The triglyceride, VLDL, total cholesterol/HDL, and non-HDL levels were significantly higher and HDL level was significantly low in the patient group (both p <0.05). Regarding thiol-disulphide balance, native thiol, total thiol, and albumin values were found to be statistically significantly low in the patient group (p <0.05), and the IMA, index-1, index-2, and index-3 values were significantly high (p <0.05). CONCLUSION: The oxidant/antioxidant balance shifted towards oxidation in patients with asymptomatic gallstones. The non-HDL value was increased. There was a positive correlation between the thiol-disulphide parameters and the non-HDL value. The increasing non-HDL amount could be effective in the pathogenesis of gallstone disease by disrupting the oxidative balance. KEY WORDS: Cholelithiasis, Thiol-disulphide homeostasis, Lipid profile, Non-HDL, HDL, Oxidative stress.

Similarities and Differences Between Gerontal and Young Patients with Acute Pancreatitis: Evaluation of Clinical Characteristics and Outcomes.

BACKGROUND: Acute pancreatitis is an abrupt inflammatory disease of the exocrine pancreas and it can occur in different severities. It is becoming more common and more mortal in the gerontal population. The aim of our study was to explore the similarities and differences between young and gerontal patients with acute pancreatitis, with a special emphasis on patients over 80 years of age. METHODS: Medical records of patients (n = 1150) with acute pancreatitis were analyzed retrospectively. Several scoring systems including Bedside index for severity in acute pancreatitis, Ranson's score, Harmless acute pancreatitis score, Acute Physiology and Chronic Health Evaluation, Balthazar Grade, Glasgow score, and Japanese severity score were applied at admission. Patients were divided into 3 groups; group I, young group (n = 706), if they were aged <65 years; group II, older group (n = 338), if they were aged ≥65 years to <80 years; group III, octogenarian group (n = 106), if they were aged ≥ 0 years. RESULTS: In total, 1150 patients with acute pancreatitis were analyzed. Octogenarian group (n = 42, 39.6%) showed a more severe acute pancreatitis compared to patients in group I (n = 15, 2.1%) and II (n = 50, 14.8%, P < .001). Complications were more common in patients in group III (P < .001). Mortality rate was higher in patients in group III (n = 53, 50%) compared to group I (n = 8, 1.1%) and group II (n = 53, 15.7%) (P < .001). CONCLUSION: Gerontal patients with acute pancreatitis tend to have more severe disease and systemic and local complications. Mortality rates were higher in older patients compared to younger patients.

Awareness, treatment rates, and compliance to treatment in patients with serum LDL cholesterol higher than 250 mg/dL, and possible, probable, or definite familial hypercholesterolemia.

PURPOSE: Familial hypercholesterolemia (FH) is a genetic disease characterized by increased levels of low-density lipoprotein cholesterol (LDL-C). It is underdiagnosed and undertreated despite relatively high prevalance and significant association with increased mortality. We aimed to determine treatment status and compliance in patients with LDL-C ≥ 250 mg/dL and FH. DESIGN: Patients older than 18 years old and have a serum LDL-C ≥ 250 mg/dL between January 2010 to December 2016 were identified from the hospital database. A phone survey was performed. Demographic features, smoking status, alcohol use, exercise, cardiovascular disease (CVD), use of medication for dyslipidemia, and CVD and high cholesterol levels in the family were questioned. Dutch Lipid Clinical Network Criteria was used to classify patients. The study was registered to Clinicaltrials.gov in July 2020 (NCT04494464). RESULTS: 1365 patients with a LDL-C ≥ 250 mg/dL were identified. Patients that could not be reached and who refused to interview were excluded and the data of 367 patients were analyzed. There were 248 (67.6%) female and 119 (32.4%) male patients and mean age was 50.52 ± 11.66. LDL-C was ≥330 mg/dL in 50 (13.6%) and 250-329 mg/dL in 317 (86.4%) patients. Forty (10.9%) patients were classified as definite, 181 (49.3%) as probable and 146 (39.8%) as possible FH. 213 (58.0%) patients were not receiving lipid-lowering treatment, and 162 (76.1%) stated that medication was never recommended previously, 30 (14.1%) had stopped medication him/herself and 21 (9.8%) had stopped medication with the advice of the physician. Among patients with definite/probable FH, 84 (38.0%) had CVD and the rate of lipid-lowering drug use in these patients was 58.3%. CONCLUSION: A significant proportion of patients with LDL-C ≥ 250 mg/dL were not taking lipid-lowering drugs. Similar with many other studies, diagnosis, and treatment rates of FH patients were very low in our study. Further national studies are required to increase awareness of the disease in both physicians and patients.

Assessing Oxidative Stress by Thiol/Disulfide Homeostasis Among Vitamin D-Deficient Patients.

OBJECTIVE: Thiol/disulfide (T/DS) homeostasis represents a promising new approach to evaluate oxidative stress. Therefore, we aimed to examine T/DS homeostasis in vitamin D (VitD)-deficient patients. METHODS: We enrolled 154 patients with VitD deficiency and 154 healthy control subjects in the study. For both groups, native thiol, total thiol, and disulfide values were measured. Additionally, considering the obtained 25-hydroxycholecalciferol [25(OH)D] levels, the patient group was further divided into two subgroups (Group 1: <10 ng/mL, Group 2: 10-20 ng/mL), which were compared in more depth according to the specified parameters. RESULTS: Values of native thiol, total thiol, and disulfide measured in the combination of Groups 1 and 2, comprising individuals with VitD deficiency, proved to be higher in comparison to the control group with statistical significance (p=0.007, p=0.028, and p<0.001, respectively). When subgroups were considered according to VitD classifications, native thiol and total thiol were again higher in Group 1 in comparison to the values obtained for control subjects (p=0.022; p<0.001). While the total thiol level of Group 2 was higher than that of controls (p<0.001), no difference with statistical significance was obtained in the comparison of disulfide levels among the indviduals of Group 1, Group 2, and the controls (p=0.081). CONCLUSION: In this study, among patients with VitD deficiency, we have confirmed that values of native thiol and total thiol were increased, while the T/DS balance was found to have shifted in favor of the thiol level.

Capability of capsule endoscopy in detecting small bowel ulcers.

Capsule endoscopy (CE) has proved to be the preferred modality for mucosal pathologies of the small bowel. We evaluated the capability of CE for detecting small bowel ulcers and the contribution of CE in establishing the diagnosis. From a total of 66 patients who had undergone normal upper and lower endoscopy and small bowel follow-through, CE revealed previously undiagnosed ulcer(s) in the small intestines of 22 patients. Final diagnoses of the ulcers of these 22 patients were Crohn's disease (n = 9), Behçet's disease (n = 2), nonspecific jejunoileitis (n = 2), vasculitis (n = 1), gastrointestinal stromal tumor (n = 1), adenocarcinoma (n = 1), lymphoma (n = 1), multiple myeloma (n = 1), Meckel's diverticulum (n = 1) and unknown (n = 3). Capsule endoscopy was extremely useful in establishing the diagnosis. In this study, proximal, distal and diffuse small bowel ulcers were determined at rates of 27.3, 59.0 and 13.7%, respectively. Capsule endoscopy facilitated the detection and assessment of ulcerated mucosal lesions located in the small bowel.

Capsule endoscopy findings in celiac disease.

Capsule endoscopy (CE) is a noninvasive imaging method used to evaluate intestinal mucosa. We aimed to examine intestinal mucosal changes in celiac disease (CD) with CE. Eight untreated patients who had anti-endomysial antibody-positive duodenal biopsy results consistent with CD were included in the study. Villous atrophy, scalloping, fissuring, and mosaic pattern (consistent with CD) were detected in seven patients; one patient was excluded for early meal consumption. No patchy involvement was found in the intestine or distal region of the intestine (ileum) in any of the patients. The common feature of all patients was that villous atrophy, scalloping, fissuring, and mosaic patterns detected in the proximal intestine gradually decreased towards the distal intestine. CE provided no diagnostic contribution to CD when compared with duodenal biopsy. It can be used to show villous atrophy in selected cases and to evaluate the extension of intestinal involvement in CD.
