Aleurites moluccanus is used in folk medicine to treat many diseases including pain and inflammatory processes in general. Considering the potential of the leaf extract, evidenced in a previous study, the present study investigates the antinociceptive and anti-inflammatory properties of the hydroethanolic extract of A. moluccanus bark and isolated compounds in animal models of pain. The antinociceptive and anti-inflammatory activities of A. moluccanus bark were evaluated through hyperalgesia induced by carrageenan, PGE2, cytokines, bradykinin, epinephrine, Freund's complete adjuvant, and lipopolysaccharide. Five compounds were isolated from the dichloromethane bark extract acetyl aleuritolic acid, atraric acid, spruceanol, (5β,10α)-12-hydroxy-13-methoxy-8,11,13-podocarpatrien-3-one and sonderianol. To optimize the extraction conditions, ethanol 50, 70, and 90°GL were used as extracting solvent, in a 1  20 (w/v) drug  solvent ratio, under stirring at room temperature for 4 h. The extracts were named AMC50, AMC70, and AMC90, respectively. These extracts were administered to mice (250 mg/kg, p. o.) with reduced mechanical hyperalgesia activity in the carrageenan test. Of these, AMC90 showed the best results. Pure (5β,10α)-12-hydroxy-13-methoxy-8,11,13-podocarpatrien-3-one showed a beneficial effect for up to 48 hours after the administration of carrageenan, while acetyl aleuritolic acid was effective only in the first hour. AMC90 was able to reverse the analgesia induced only by prostaglandin E2 and tumor necrosis factor. We also induced hyperalgesia using the lipopolysaccharide and Freund's complete adjuvant models, with positive results. These results support the antinociceptive and anti-inflammatory activity of A. moluccanus bark extract. The observed effects are partly due to the presence of acetyl aleuritolic acid, atraric acid, and (5β,10α)-12-hydroxy-13-methoxy-8,11,13-podocarpatrien-3-one.

 Buried bumper syndrome (BBS) is a severe complication of percutaneous endoscopic gastrostomy (PEG) resulting from overgrowth of gastric mucosa and penetration of the inner holding plate into the gastric wall. The aim of this study was to evaluate the diagnostic value of transabdominal ultrasound (US) in comparison to an artificial intelligence (AI) model for the diagnosis of BBS in children.

 In this monocentric retrospective study, pediatric US data concerning BBS from a ten-year period (2009-2019) were analyzed. US findings were compared to a clinical multiparameter-based AI model and reference standard endoscopy. Clinical risk factors for the occurrence of pediatric BBS were determined.

 In n = 121 independent examinations of n = 82patients, the placement of the inner holding plate of the PEG was assessed by US. In n = 18 cases BBS was confirmed. Recall and precision rates were 100 % for US and 88 % for the AI-based assessment. Risk factors for the occurrence of BBS were mobilization problems of the PEG (r

 = 0.66, p < 0.001), secretion/exudation (r

 = 0.29, p = 0.002), time between 1

PEG placement and US (r

 = 0.38, p < 0.001), and elevated leukocyte count (r

 = 0.24, p = 0.016).

 Transabdominal US enables correct, rapid, and noninvasive diagnosis of BBS in pediatric patients. Preceding AI models could aid during diagnostic workup. To avoid unnecessary invasive procedures, US could be considered as a primary diagnostic procedure in suspected BBS. .

 Diagnosis of Parkinson's disease and atypical parkinsonism is based on clinical evaluation of the patient's symptoms and on magnetic resonance imaging (MRI) of the brain, which can be supplemented by nuclear medicine techniques. MRI plays a leading role in the differentiation between Parkinson's disease and atypical parkinsonism. While atypical parkinsonism is characterized by relatively specific MRI signs, imaging of Parkinson's disease previously lacked such signs. However, high-field MRI and new optimized MRI sequences now make it possible to define specific MRI signs of Parkinson's disease and have significant potential regarding differentiated imaging, early diagnosis, and imaging of disease progression.

 PubMed was selectively searched for literature regarding the definition and discussion of specific MRI signs of Parkinson's disease, as well as the most common types of atypical parkinsonism with a leading motor component. No time frame was set, but the search was particularly focused on current liodromal stages of Parkinson's disease. · The combination of specific MRI signs makes it possible to differentiate between Parkinson's disease and atypical parkinsonism.

 Clinical signs and symptoms related to invasive fungal disease are nonspecific and need to be followed up by appropriate diagnostic procedures. The goal of this study was to analyze CT imaging patterns in invasive fungal infections and their correlation with the immune status and clinical outcome.

 We performed a retrospective multicenter study including 85 consecutive patients with invasive pulmonary fungal infection (2011-2014). Lung patterns on computed tomography (CT) scans were classified according to the Fleischner Society glossary. The patients were grouped according to immune status (neutropenia, steroid therapy, organ transplant recipient, and other cause) and outcome (positive outcome, progressive disease, and death). The Chi square test or Fisher exact test was used. Bonferroni correction was applied.

 The total number of patients with invasive Aspergillus and non-Aspergillus infection (IANA), Pneumocystis jirovecii pneumonia (PCP), and Cryptococcus (CRY) was 60, 22, and 3, respectively. Patients with IANA demonstrated significantly more nodules (93 % vs.
