Background: Exhaled Volatile Organic Compounds (E-VOCs) may help to early detection of colonic polyps Objective: Assess whether a new ambulatory device is able to detect specific E-VOCs in patients recently diagnosed with colonic polyps. Material and Methods: All data were collected during routine consultations for Small Intestinal Bowel Overgrowth. A breath test was performed by X-PID 9500®. Results: 203 patients older than 45 years of age were included. 31patients (15.3%) reported colonic polyps. 74 patients presented with gastroduodenal or jejunal (GDJ) liquid at ultrasound examination despite fasting. 96 patients (47.3%) exhaled numerous E-VOCs with a retention time between 12 to 45s (E-VOCs 12 to 45s). All patients of the polyp group exhaled E-VOCs 12 to 45s. 69 patients with GDJ liquid exhaled E-VOCS 12 to 45s. 11 patients out of these 69 cases (15.9%) present with polyps. 27 patients exhaled E-VOCs 12 to 45s and did not have GDJ, 20 of whom (74.1%) presented with polyps. When GDJ liquid is not objectivized after fasting, the sensitivity of the E-VOCs 12 to 45s to identify patients with colonic polyps is equal to 100.0% and the specificity is 93.6%. The positive predictive value is 74.1% and the negative predictive value is 100%. Conclusion: After fasting, X-PID 9500® is able to detect E-VOCs associated with colonic polyps, when GDJ liquid is excluded.

Intramucosal lipomas are rare colonic polyps that pose diagnostic challenges, but they are important as potential clues to serious medical conditions. One third of intramucosal lipomas are reported to arise in Cowden syndrome, an inherited cancer syndrome.

Undetected colonic polyps are considered a major cause of interval cancer of the colon. The Automatic Polyp Detection System (APDS) (Magentiq Eye LTD, Haifa, Israel) was developed to enhance the ability of endoscopists to detect polyps during screening colonoscopy. It is designed to be used both in real-time and offline. APDS runs directly on the video output of the endoscopic camera and highlights the polyp on the screen. APDS utilizes the power of Deep Learning and Computer Vision in order to improve polyp detection rates thus improving the performance of the endoscopist.

Demyelination induced by cuprizone-is a widely used experimental model to analyze processes of re- and demyelination in the central nervous system (CNS). Here we used C57BL/6 mice; a model of experimental autoimmune encephalomyelitis (EAE) mimicking important aspects of human multiple sclerosis, to evaluate effects of cuprizone-dependent demyelination on different parameters associated with autoimmune inflammation. The treatment of mice with cuprizone leads to a significant decrease of several indexes characterizing spontaneous and myelin oligodendrocyte glycoprotein (MOG35-55)

Iatrogenic splenic injury is a known but rare complication of colonoscopic procedures. Our department describes a very interesting case of the same complication that occurred twice on the same patient. The patient had an elective colonoscopy for microcytic anemia and shortly after the endoscopic procedure she developed excessive abdominal pain and had a syncope episode. She gradually became hemodynamically unstable and needed proper resuscitation. An abdominal tomography scan performed which surprisingly demonstrated active intra-abdominal bleeding pointing a ruptured spleen as the source of the hemorrhage. This finding surprised us given the fact that her past surgical history included a previous splenectomy for the same complication 14 years ago.

During the 19th Century, there was a difficult choice concerning whether a pancreatic cancer is primary or secondary. However, in this paper, it is shown that some views were decidedly in favor of attack from other primaries. Indeed, the evidence of spread to the pancreas included either concise or coalescent lesions.

Cutaneous metastases from abdominal malignancies are rare and have been reported in less than 5% of patients [1]. Furthermore, metastases in patients suffering from colorectal neoplasia are even rarer entity. Tan et al, among 2538 of the new cases of colorectal cancer over the period of 6 years, reported only 3 cases (0.1%) with cutaneous deposits [1]. Presentation varies from cutaneous or subcutaneous small nodules, rash or large fungating lesions [1-4]. Inevitably, their presence implies the disease progression, and poor prognosis with the reported survival between 1 to 34 months [2,3,5].
