RESUMO
Background: Inflammatory bowel disease (IBD) patients are at increased risk of Clostridium difficile infection (CDI), causing significant morbidity and mortality. This study examined CDI's prevalence, predisposing factors, and clinical outcomes in Saudi hospitalized IBD patients. Methods: : A retrospective case-control study was conducted at a tertiary medical city in Riyadh, Saudi Arabia. All Saudi adult patients with IBD, admitted over the preceding four years were identified from the hospital's database. Eligible patients were divided into those with CDI and those without CDI. Binary logistic regression was used to determine the predisposing factors for CDI among admitted IBD patients. Results: During the study period, 95 patients were admitted with IBD. Crohn's disease (CD) was the predominant type (71.6%), whereas 28.4% of the patients were with ulcerative colitis (UC). Only 16 (16.8%) patients had positive CDI. CDI-positive patients tend to have hypertension and previous use of steroids. Patients with UC tend to have a higher risk of CDI than those with CD. Most patients recovered from the CDI (81.3%) with a median time to CDI clearance of 14 days. Three patients (18.8%) had recurrent CDI; among them, one died. Conclusion: The prevalence of CDI in Saudi IBD patients is similar to that reported elsewhere. UC, steroid treatment, and hypertension are risk factors for CDI in IBD patients. Recurrence of CDI in IBD patients is common and associated with a poor prognosis.

BACKGROUND: Blood in the stomach and esophagus in patients with variceal bleeding often obscures the endoscopic view and makes endoscopic intervention difficult to perform. Erythromycin, a motilin agonist, induces gastric emptying. OBJECTIVE: To assess the effect of erythromycin on endoscopic visibility and its outcome in patients with variceal bleeding. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Tertiary care hospital. PATIENTS: Adult patients with liver cirrhosis presenting with hematemesis within the previous 12 hours. INTERVENTION: Either 125 mg erythromycin or placebo administered intravenously 30 minutes before endoscopy. MAIN OUTCOME MEASUREMENTS: Endoscopic visibility during index endoscopy and mean duration of procedure. SECONDARY OUTCOME MEASUREMENTS: Need for repeat endoscopy and blood transfusions within 24 hours, endoscopy-related complications, and length of hospital stay. RESULTS: A total of 102 patients received either erythromycin or placebo (53 erythromycin and 49 placebo). Forty-seven patients in the erythromycin group and 43 in the placebo group had variceal bleeding and were considered for final analysis. A completely empty stomach was seen in 48.9% of the erythromycin group versus 23.3% of the placebo group (P<.01). Mean endoscopy duration was significantly shorter in the erythromycin group than in the placebo group (19.0 minutes vs 26.0 minutes, respectively; P<.005). Length of hospital stay was significantly shorter in the erythromycin group than in the placebo group (3.4 days vs 5.1 days, respectively; P<.002). The need for repeat endoscopy and the mean number of units of blood transfused did not differ significantly in the 2 groups. No adverse events were observed with erythromycin. LIMITATIONS: Sample size not sufficient to measure the need for repeat endoscopy and survival benefit. CONCLUSIONS: Erythromycin infusion before endoscopy in patients with variceal bleeding significantly improves endoscopic visibility and shortens the duration of the index endoscopy.

BACKGROUND: Khat is known to have a stimulating effect on the sympathetic nervous system by producing a temporary sensation of activeness and happiness, along with mood disturbance and anxiety. Despite growing evidence of the association between khat chewing and glycaemic control in patients with diabetes, the position of khat chewing in DM is not fully recognised. AIM: To evaluate the association of khat chewing with the risk of elevated blood glucose levels among patients with type 2 diabetes mellitus. METHOD: A web-based literature search was performed using the electronic databases PubMed, EMBASE and Google Scholar. Databases were searched for studies published about khat chewing and diabetes mellitus in the Jazan region, Saudi Arabia and Yemen. RESULT: Twenty-five published articles studying the relation between khat chewing and diabetes mellitus were identified, but only 10 studies reported an association between khat chewing and blood glucose levels and were included. CONCLUSION: Khat chewing increases fasting blood glucose, post-prandial blood glucose and HbA1c levels in patients with diabetes in the Jazan region, Saudi Arabia and Yemen.

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma that histologically resembles embryonic skeletal muscle. It is a rare malignancy in adults with a predilection in the head and neck, the genitourinary tract, and other extremities. However, RMS of the gastrointestinal tract is an even rarer condition that merits presentation and discussion. Here, we report on a case of primary duodenal embryonal RMS in an adult.
RESUMO
Gastric antral vascular ectasia (GAVE) is a rare but an important cause of upper gastrointestinal bleeding (UGIB) and commonly presents as occult bleeding that manifests as iron deficiency anemia (IDA). GAVE is commonly associated with chronic illnesses, most frequently liver cirrhosis and connective tissue diseases. The pathogenesis of GAVE is still obscure, and many hypotheses such as mechanical stress, hormonal factors, and autoimmune factors, have been proposed. Upper gastrointestinal endoscopy has a major role in the diagnosis and treatment of GAVE.
RESUMO
BACKGROUND/AIM: No prior experience with video capsule endoscopy (VCE) has been published from Saudi Arabia. In this study, we aim to report the first Saudi experience with VCE. PATIENTS AND METHODS: A prospective study was conducted between March 2013 and September 2017 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Eligible patients underwent VCE and their data (age, sex, indication for VCE, type of obscure gastrointestinal bleeding [OGIB: overt vs occult], VCE findings, and complications) were recorded. Approval was obtained from the institutional ethics board before the study began and all patients provided verbal and signed consent for the procedure. The procedure was performed according to the established guidelines. RESULTS: During the study period, a total 103 VCE procedures were performed on 96 patients. Overall, 60 participants (62.5%) were male (mean age, 58.8 years; range, 25-97 years) and 36 (37.5%) were female (mean age, 52.8 years; range, 18-78 years). The most frequent indication for VCE was OGIB (n = 91, 88.35%; overt, n = 46, 50.55%; occult, n = 45, 49.45%). Other indications were suspected Crohn's disease (n = 4, 3.88%), suspected complicated celiac disease (n = 4, 3.88%), and unexplained chronic abdominal pain (n = 4, 3.88%). The VCE results were categorized as incomplete (n = 2, 1.94%), poor-quality (n = 7; 6.8%), normal (n = 39, 37.86%), and abnormal (n = 55, 53.4%). The completion rate was 98.06% (n = 101), and the overall diagnostic yield was 53.4%. Of the 55 patients with abnormal VCE results, 43 (78.2%) had small bowel (SB) abnormalities and 12 (21.8%) had abnormalities in the proximal or distal gut. The most frequent SB abnormalities were angiodysplasia (n = 22, 40.0%) and tumors (n = 7, 12.7%). CONCLUSION: The diagnostic yield of VCE for Saudi patients with OGIB is comparable to that reported internationally; however, data for other VCE indications, including inflammatory bowel disease, are still lacking.
