    Five out of seven human studies reported elevated levels of MMP-9 in patients with anastomotic leakage on different postoperative moments. The animal studies demonstrated that MMP-9 activity was highest in the direct vicinity of an anastomosis. Moreover, MMP-9 activity was significantly reduced in areas further proximally and distally from the anastomosis and was nearly or completely absent in uninjured tissue.

    Current literature shows some relation between MMP-9 activity and colorectal AL, but the evidence is inconsistent. Innovative techniques should further investigate the value of MMP-9 as a clinical biomarker for early detection, prevention, or treatment of AL.

    Endoscopic migration of plastic biliary stents is performed by endoscopic retrograde cholangiopancreatography (ERCP) for biliary and pancreatic diseases. This plays an increasingly important role. Intestinal perforation caused by stent migration is one of the complications. Although sigmoid colon perforation caused by stent migration is rare, it can be life-threatening. This case shows us that we should increase awareness of sudden abdominal pain after ERCP.

    We provide a review of the clinical manifestations, imaging data of this case, and the literature related to the perforation caused by stent migration.

    A male patient had a history of choledocholithiasis, cholecystolithiasis, and biliary pancreatitis treated with ERCP and a pancreatic stent. After the operation, the patient developed cholangitis and was treated with ERCP and a plastic biliary stent. This patient was admitted to the emergency department with sudden lower abdominal pain. A CT scan showed sigmoid colon perforation by a foreign body and infra-diaphragmatic free air. An emergency surgery confirmed that the stent had caused the perforation. The patient was then treated with sigmoid colectomy and sigmoidostomy.

    Biliary stent migration after ERCP is rare, but intestinal perforation caused by migration should be considered in cases of abdominal pain of unknown cause.

After fermentation at 37 °C by mono- or co-cultures of Streptococcus thermophilus (St), Lactobacillus bulgaricus (Lb), and Lactobacillus paracasei (Lp), fermented soymilk was cooled directly at 4 °C for 28 days or cooled in two phases (TPC), i.e., by preceding that step by another at 25 °C for 8 h. Soybean milk fermentation by Lb alone lasted longer (15 h) than by StLb or StLbLp (9 h). In ternary culture, TPC increased Lp viability, linoleic, and lactic acid concentrations by 3.8, 22.6, and 96.2%, respectively, whereas the cooling protocol did not influence Lp and St counts after in vitro gastrointestinal stress. check details Graphical abstract.

    Although hypomineralised second primary molars (HSPM) are considered belonging in the same entity as molar incisor hypomineralisation (MIH), the structure and chemistry of their defected enamel have not been described. We aimed to study these in justifying any similarities with MIH.

    Nine HSPM and five first permanent molars with MIH were either fractured or sectioned longitudinally through their defective enamel and examined by scanning electron microscopy. Relative amounts of calcium (Ca), phosphorus (P), oxygen (O), carbon (C) and the CaP ratio were calculated in the primary molar samples by energy -dispersive spectrometry.

    Rod width was deficient in the defected enamel of HSPM resulting in wide interrod spaces and suggesting similarities to permanent enamel structure in MIH. In areas with breakdown, cracks and disrupted coherence between enamel rods were more marked. Differences in Ca, P, O, C and CaP ratio between hypomineralised and sound enamel in HSPM followed the same trend as in MIH without reaching statistical significance.

    Marked structural differences between sound and hypomineralised enamel of HSPM and similarity to MIH enamel were verified.

Nonocclusive mesenteric ischemia (NOMI) is a rare complication of PD-related peritonitis, has a high mortality rate, and therefore should be detected early once it occurs. We describe a case of a 70-year-old woman on PD presented with moderate abdominal pain and low blood pressure, which contributed to the early diagnosis of PD-related peritonitis complicated with NOMI. Increased white cell count of 7150/μL (neutrophil, 84%) in dialysate effluent was diagnostic of PD-related peritonitis, which was later found to be caused by Pseudomonas putida. Computed tomography with contrast performed after administering crystalloids revealed hepatic portal venous gas, pneumatosis intestinalis in the ascending colon, and normal enhancement of the bowel wall and mesenteric arteries, which suggested a reperfusion of the previously ischemic ascending colon. Colonoscopy on hospital day seventeen revealed mucosal hemorrhage and ulcers in the entire right colon and the terminal ileum while the remaining colon was normal. These findings are compatible with the consequence of NOMI. Increased peak systolic velocity of the superior mesenteric artery (SMA) implied its stenosis. Past studies show that ischemia of the colon in patients with chronic kidney disease commonly occurs in the right colon. Arteriosclerosis of the SMA due to the long history of chronic kidney disease and diabetes might have caused its vulnerability to low blood pressure. Abdominal complications including NOMI should be screened for when a patient presents with low blood pressure and strong abdominal pain. This is the first case report that shows colonoscopy images of the colonic ulcers post-NOMI and PD-related peritonitis.
