    Although most patients with acute pancreatitis have the mild form of the disease, about 20-30% develops a severe form, often associated with single or multiple organ dysfunction requiring intensive care. Identifying the severe form early is one of the major challenges in managing severe acute pancreatitis. Infection of the pancreatic and peripancreatic necrosis occurs in about 20-40% of patients with severe acute pancreatitis, and is associated with worsening organ dysfunctions. While most patients with sterile necrosis can be managed nonoperatively, patients with infected necrosis usually require an intervention that can be percutaneous, endoscopic, or open surgical. These guidelines present evidence-based international consensus statements on the management of severe acute pancreatitis from collaboration of a panel of experts meeting during the World Congress of Emergency Surgery in June 27-30, 2018 in Bertinoro, Italy. The main topics of these guidelines fall under the following topics: Diagnosis, Antibiotic treatment, Management in the Intensive Care Unit, Surgical and operative management, and Open abdomen. © 2019 The Author(s).

    Acute kidney injury (AKI) occurs in up to 50% of all critically ill patients and hemodynamic abnormalities are assumed to contribute, but their nature and share is still unclear. We explored the associations between hemodynamic variables, including cardiac index and right ventricular function, and the occurrence of AKI in critically ill patients. In this prospective cohort study, we included all patients acutely admitted to an intensive care unit (ICU). Within 24 h after ICU admission clinical and hemodynamic variables were registered including ultrasonographic measurements of cardiac index and right ventricular function, assessed using tricuspid annular plane systolic excursion (TAPSE) and right ventricular systolic excursion (RV S'). Maximum AKI stage was assessed according to the KDIGO criteria during the first 72 h after admission. Multivariable logistic regression modeling was used including both known predictors and univariable significant predictors of AKI. Secondary outcomes were days alive outside ICU and 90-day mortality. A total of 622 patients were included, of which 338 patients (54%) had at least AKI stage 1 within 72 h after ICU admission. In the final multivariate model higher age (OR 1.01, 95% CI 1.00-1.03, for each year), higher weight (OR 1.03 CI 1.02-1.04, for each kg), higher APACHE IV score (OR 1.02, CI 1.01-1.03, per point), lower mean arterial pressure (OR 1.02, CI 1.01-1.03, for each mmHg decrease) and lower TAPSE (OR 1.05, CI 1.02-1.09 per millimeter decrease) were all independent predictors for AKI in the final multivariate logistic regression model. Sepsis, cardiac index, RV S' and use of vasopressors were not significantly associated with AKI in our data. AKI patients had fewer days alive outside of ICU, and their mortality rate was significantly higher than those without AKI. In our cohort of acutely admitted ICU patients, the incidence of AKI was 54%. Hemodynamic variables were significantly different between patients with and without AKI. A worse right ventricle function was associated with AKI in the final model, whereas cardiac index was not.

We explored the associations between hemodynamic variables, including cardiac index and right ventricular function, and the occurrence of AKI in critically ill patients. Methods In this prospective cohort study, we included all patients acutely admitted to an intensive care unit (ICU). Within 24 h after ICU admission clinical and hemodynamic variables were registered including ultrasonographic measurements of cardiac index and right ventricular function, assessed using tricuspid annular plane systolic excursion (TAPSE) and right ventricular systolic excursion (RV S’). Maximum AKI stage was assessed according to the KDIGO criteria during the first 72 h after admission. Multivariable logistic regression modeling was used including both known predictors and univariable significant predictors of AKI. Secondary outcomes were days alive outside ICU and 90-day mortality. Results A total of 622 patients were included, of which 338 patients (54%) had at least AKI stage 1 within 72 h after ICU admission.

    Gynekologiset vuotohäiriöt ovat tavallisin syy naistentautien poliklinikoiden potilaskäynteihin. Tärkeää vuotohäiriöiden selvittelyssä on tarkka vuotoanamneesi ja kliininen tutkimus. Hoidot aloitetaan perusterveydenhuollossa. Erikoissairaanhoidossa potilaan jatkotutkimuksiin kuuluvat emättimen kautta tehtävä kaikukuvaus ja sen yhteydessä tehtävä keittosuolaruiskutus kohdunsisäisen rakenteellisen muutoksen poissulkemiseksi. Erikoissairaanhoidossa vuotohäiriöiden hoidon suunnittelu tapahtuu ensikäynnin yhteydessä. Merkittävä osa kohdunsisäisistä toimenpiteistä voidaan nykyään tehdä polikliinisesti, jolloin toiminta on potilaslähtöistä ja kustannusvaikuttavaa.

    Background: Diagnostic scoring is used to stratify patients with suspected appendicitis into three groups: high, intermediate, and low probability of appendicitis. The stratification can be used for selective imaging to avoid the harms of radiation without compromising diagnostic accuracy. The aim was to study how stratification by Adult Appendicitis Score affects diagnostic performance of imaging studies. Methods: Analysis of 822 patients who underwent diagnostic imaging for suspected appendicitis was made. Adult Appendicitis Score was used to stratify patients into groups of high, intermediate, and low probability of appendicitis. Diagnostic performance of computed tomography (CT) and ultrasound (US) was compared between these patient groups. Results: After scoring, pre-test probability of appendicitis ranged from 9-16% in low probability group to 75-79% in high probability group in patients who underwent US or CT. Post-test probability of appendicitis after positive CT was 99, 91, and 75% in high probability, intermediate probability and low probability groups, respectively, p <0.001. After positive US the respective probabilities were 95, 91 and 42%, p <0.001. Conclusion: Diagnostic imaging has limited value in patients with low probability of appendicitis according to Adult Appendicitis Score.

    This case report describes the radiographic and ultrasonographic findings of three surgically confirmed cases of mesenteric volvulus or intestinal torsion in dogs. In all three cases, ultrasonographic findings included segmental ileus and absent or markedly reduced peristalsis of the affected small intestine, and partial loss of wall layering with increased overall echogenicity of the intestinal wall, but with normal to mildly increased wall thickening. No blood flow was detected in the affected small intestinal wall when assessed with colour Doppler. A moderate amount of peritoneal effusion was also detected with hyperechoic omental and mesenteric fat tissue throughout the peritoneal cavity. Few reports describe ultrasonographic findings of small intestinal ischemia in small animals. In all three cases presented here, ultrasound was helpful in demonstrating typical intestinal wall changes and helped to obtain the correct diagnosis of ischemic disease of the small intestine.
