Irritable bowel syndrome (IBS) is a benign condition of the gastrointestinal tract causing abdominal pain, bloating, diarrhea, and/or constipation. Symptoms of IBS usually improve on passing flatus and defecation. There is no known identifiable underlying pathology; however, several risk factors are known to contribute to the development of IBS, which include a stressful lifestyle and certain foods such as bread, coffee, alcohol, pasta, and chocolates. Intestinal bacteria may also contribute to symptoms of IBS. IBS is diagnosed clinically and treated with various medications to control the symptoms. On the other hand, celiac and mesenteric artery thrombosis (CAMAT) is a condition that may cause significantly higher mortality and morbidity if not recognized early. CAMAT leads to the blockage of major blood vessels to the intestine and several abdominal viscera leading to abdominal pain, nausea, sweating, and, in some cases, symptoms of shock. CAMAT is most likely caused by thrombosis; however, occasionally, embolisms from distant sources in patients with atrial fibrillation can also contribute to the development of CAMAT. CAMAT is usually diagnosed with a computed tomography angiogram (CTA) and treated either surgically or medically with anticoagulants. Vascular thrombus in the thoracic and abdominal region causing ischemia of the stomach and abdominal pain in patients with a history of IBS can easily be missed and cause grave complications with high morbidity and mortality. We present two cases who were initially diagnosed and treated for IBS and later diagnosed with serious intra-abdominal pathology of CAMAT thrombosis.The first case is of a 55-year-old female who was previously diagnosed with IBS and was treated with mebeverine 200mg twice daily and esomeprazole 20mg once daily for 10 weeks. Her pain continued to get worse and she presented to the emergency department by ambulance. She underwent CTA, which showed occlusion of the celiac trunk and superior mesenteric artery causing liver and splenic infarcts. The patient received heparin and underwent a thrombectomy and embolectomy of the superior mesenteric and celiac arteries. No significant abnormality was found in the blood results. Thrombophilia screening was negative. The patient was discharged on warfarin. The second case is of a 53-year-old man who was also initially diagnosed with IBS and was treated with mebeverine 200mg twice daily for eight weeks before presenting to the emergency department with worsening abdominal pain. He underwent a CTA with contrast, which showed occlusion of the common hepatic artery and stenosis of the splenic artery leading to multiple splenic infarcts. No significant abnormality was found in blood test. Thrombophilia screening was negative. He was treated with new anticoagulant medication, dabigatran 150 mg orally twice daily.Both patients were managed with successful outcomes and were discharged home on anticoagulants. There was no recurrence of symptoms at three-month follow-up.These cases highlight that a secondary cause ...

Background: Emergency Medicine didactic teaching has traditionally been delivered through face-to-face (F2F) lectures. However, during the pandemic of COVID-19, the didactic teaching was switched to online through using Microsoft Teams. The aim of this study was to assess the impact of online learning in the knowledge and skills acquisition of millennial learners based within emergency medicine. Methodology: This was a retrospective review of assessment data. Over a period of 10 months (August 2019 to June 2020), each resident was exposed to traditional F2F teaching for a period of four months and then online teaching in a crossover manner. After each method, there were two types of assessments, multiple-choice questions (MCQs) and computer-based objective structured clinical examination (OSCE). A total of 20 MCQs with one correct answer, totaling 20 marks, and 20 OSCEs consisting of an image or a video with five options, each option carrying one mark, totaling 100 marks were used at each assessment point. A student t-test was used to compare the two groups of results. Results: The total number of participants was 49 (n=49). All residents belonged to the millennial generation. Fourteen were female and 35 were male. The mean MCQ 1 score after F2F teaching was 12.16 (SD=1.688), whilst the mean MCQ 2 score after online teaching was 13.40 (SD=1.861). The mean computer-based OSCE 1 score after F2F teaching was 64.45 (SD=5.895), whilst the mean OSCE 2 score after online teaching was 65.57 (SD=5.969). Ten out of 49 students (20.4%) failed the MCQ exam after F2F teaching, whilst 6/49 students (12.2%) failed the MCQ test after online teaching. Seven out of 49 students (14.3%) failed the OSCE exam after F2F teaching, while six out of 49 students (12.2%) failed the OSCE exam after online teaching. There was a statistically significant improvement in the MCQ score after online teaching as compared to F2F teaching (P-value 0.0003), whilst there was no statistically significant change in the OSCE between the two-teaching methods (P-value 0.3513). Conclusion: Both F2F and online teaching methods resulted in a significant improvement in the knowledge and skills of emergency medicine residents. Online education resulted in a statistically significant improvement of MCQ score as compared to F2F teaching. The difference in MCQ score may be due to millennial learners, who traditionally benefit proportionately more from self-learning that is primarily online.

Isolated pancreatic transection is a rare surgical condition that occurs more commonly following blunt abdominal trauma. It carries a high degree of morbidity and mortality, and the management remains a source of debate as universally accepted guidelines are not well established owing to the paucity in clinical experience and large series. We presented a case of an isolated pancreatic transection following blunt abdominal trauma. The surgical management of pancreatic transection has evolved over the decades from aggressive approaches to more conservative measures. Given the lack of large series and clinical experience, no universal consensus exists, except for applying damage control surgery and resuscitation principles in critically unstable patients. For transections of the main pancreatic duct, most recommend excision of the distal pancreas. Concerns over the iatrogenic complications of wide excisions, particularly diabetes mellitus, have led to reconsideration and more conservative approaches, but it may fail in some cases.
