Pancreatitis is as common in children as it is in adults, though causes and accepted imaging strategies differ in children. In this narrative review we discuss the epidemiology of childhood pancreatitis and key imaging features for pediatric acute, acute recurrent, and chronic pancreatitis. We rely heavily on our collective experience in discussing advantages and disadvantages of different imaging modalities; practical tips for optimization of ultrasound, CT, and MRI with MRCP in children; and image interpretation pearls. Challenges and considerations unique to imaging pediatric pancreatitis are discussed, including timing of imaging, role of secretin-enhanced MRCP, utility of urgent MRI, severity prediction, autoimmune pancreatitis, and best methods for serial imaging. We suggest a methodical approach to pancreatic MRI interpretation in children and have included a sample structured report, and we provide consensus statements according to our experience imaging children with pancreatitis.BACKGROUND Undiagnosed and unrepaired root tears are increasingly recognized as a preventable cause for accelerated osteoarthritis. Pre-operative MRI findings of lateral meniscus posterior root tears in children with concomitant anterior cruciate ligament (ACL) injury are not well described. OBJECTIVE To investigate performance of pre-operative MRI for identifying concomitant lateral meniscus posterior root injuries in pediatric patients with ACL tears, using arthroscopy as reference standard. METHODS Consecutive children who underwent MRI within 90 days before arthroscopic primary ACL reconstruction between March 2017 and December 2019 were included. Two radiologists assessed MRI examinations for direct signs involving the root proper and for findings associated with lateral meniscus posterior root tears. Kappa coefficients for MRI findings were computed. Findings in patients with root tears and intact roots were compared using independent samples t test, Mann-Whitney U test, chi-square test, Fisher's exact segment (OR=19.3, 95% CI 2.7-137.5, p=.003). CONCLUSION Among MRI findings evaluated for preoperative diagnosis of lateral meniscus posterior root tear, tear involving any segment of the root proper had strongest performance; associated findings had high specificity but low sensitivity. CLINICAL IMPACT Accurate identification of lateral meniscus posterior root tears on pre-operative MRI can aid in operative planning and reduce treatment delay.Among 17 women with newly diagnosed breast cancer who underwent contrast-enhanced mammography (CEM) and MRI, both modalities were concordant for the index cancer in all women. In 6/17, CEM demonstrated an additional lesion that was confirmed by MRI (2 multifocal, 1 multicentric, 2 contralateral); two were malignant. MRI did not identify any additional cancers not identified on CEM. CEM may have a role in women with breast augmentation and contraindication or limited access to MRI.Background With the emergence of coronary computed tomography (CT) angiography, anomalous aortic origin of a coronary artery (ANOCOR) is more frequently diagnosed. Fractional flow reserve derived from CT (FFRCT) is a noninvasive functional test providing anatomical and functional evaluation of the overall coronary tree. These unique features of anatomical and functional evaluation derived from CT could help for the management of patients with ANOCOR. We aimed to retrospectively evaluate the physiological and clinical impact of FFRCT analysis in the ANOCOR registry population. Methods and Results The ANOCOR registry included patients with ANOCOR detected during invasive coronary angiography or coronary CT angiography between January 2010 and January 2013, with a planned 5-year follow-up. We retrospectively performed FFRCT analysis in patients with coronary CT angiography of adequate quality. Follow-up was performed with a clinical composite end point (cardiac death, myocardial infarction, and unplanned revascularization). We obtained successful FFRCT analyses and 5-year clinical follow-up in 54 patients (average age, 60±13 years). Thirty-eight (70%) patients had conservative treatment, and 16 (30%) patients had coronary revascularization after coronary CT angiography. The presence of an ANOCOR course was associated with a moderate reduction of FFRCT value from 1.0 at the ostium to 0.90±0.10 downstream the ectopic course and 0.82±0.11 distally. No significant difference in FFRCT values was identified between at-risk and not at-risk ANOCOR. After a 5-year follow-up, only one unplanned percutaneous revascularization was reported. Conclusions The presence of ANOCOR was associated with a moderate hemodynamic decrease of FFRCT values and associated with a low risk of cardiovascular events after a 5-year follow-up in this middle-aged population.Aim We investigated the role of maternal ancestry in neoplastic hematological malignancies (HMs) risk in a population from Central Argentina. Materials & methods We analyzed 125 cases with HMs and 310 controls from a public hospital, and a set of 202 colorectal, breast, lung, and hematologic cancer patients from a private hospital. Results A decreased risk for HMs was associated with the Native American haplogroup B2 (odds ratio = 0.49; 95% CI 0.25-0.92; p = 0.02). The sub-Saharan African parahaplogroup L was associated with higher susceptibility for disease (odds ratio = 3.10; 95% CI 1.04-9.31; p = 0.043). Although the mean ancestral proportions in the total studied population was as published (61.7% Native American, 34.6% European and 3.7% African), an unequal distribution was observed between hospitals. Conclusion We confirmed the tri-hybrid nature of the Argentinean population, with proportions varying within the country. Our finding supports the notion that associated haplogroup is population and cancer specific.Background Multiple chemical sensitivity (MCS) is a chronic condition with somatic, cognitive and affective symptoms that follow contact with chemical agents at usually non toxic concentrations. We aimed to assess the role of genetic polymorphisms involved in oxidative stress on anxiety and depression in MCS. Materials & methods Our study investigated the CAT rs1001179, MPO rs2333227, PON1 rs662 and PON1 rs705379 polymorphisms in MCS. Results The AG genotype of the PON1 rs662 and the TT and CT genotypes of the PON1 rs705379 were involved in anxiety and depression. Discussion These results are in line with existing evidence of PON1 involvement in MCS and suggest a further role of this gene in the exhibition of anxiety and depression in this disease.Aim We sought to understand how early adopters used pharmacogenomic (PGx) testing for treating depression and attention deficient hyperactivity disorder (ADHD). Patients & methods We conducted a phone survey with prescribers who had previously ordered an Informed PGx (Progenity, Inc., MI, USA) test. Results We identified 1037 prescribers in our sampling period. Respondents (n = 64) were predominantly female (61.5%) and in pediatrics (n = 42; 64.6%). PGx testing was used for multiple scenarios (mean 3.3 ± 1.6); the most common was after no response to medication was observed (80%; 51/64). Most respondents state that test results typically reveal an altered metabolizer status. Conclusion PGx test results ordered by early adopters often reveal altered metabolizers which leads them to change the depression/ADHD medication regimen. Future work should evaluate the clinical utility of PGx testing for depression/ADHD treatment.Diabetes mellitus is a complex disease that leads to long-term damage to various organ systems. Among the numerous cardiovascular disease-related complications, thrombotic events frequently occur in patients with diabetes. selleck kinase inhibitor Although guidelines exist for treating and preventing most diabetes-related co-morbidities, the evidence on antithrombotic therapy in primary and secondary prevention is limited due to the scarcity of randomized trials dedicated to patients with diabetes mellitus. Most of the available data are derived from studies that only included a small proportion of patients with diabetes. The present review provides an overview of the status of knowledge on antiplatelet and anticoagulation therapy in patients with diabetes, focusing on the risk-benefit balance of these therapies and future treatment strategies.Japanese apple rust, caused by the heteroecious and demicyclic rust fungus Gymnosporangium yamadae Miyabe ex G. Yamada, can affect juniper (Juniperus spp.), where the telial stage of this disease occurs, and apple or crabapple (Malus spp.), where the aecial stage occurs (Yun, 2010). Leaf samples displaying symptoms and signs of rust disease were collected in August 2020 from 14 different crabapple cultivars ('Amerspirzam' [American Spirit®], 'Amsalzam' [American Salute™], 'Excazam' [Excalibur™], 'Guinzam' [Guinevere®], 'Hargozam' [Harvest Gold®], 'Mary Potter', 'Orange Crush', 'Prairie Maid', 'Professor Sprenger', 'Pumpkin Pie', 'Rawhide', 'Select A' [Firebird®], 'Shotizam' [Show Time™], 'Sinai Fire') in the crabapple research plot of Secrest Arboretum (Crablandia) in Wooster, OH. Samples displayed adaxial leaf lesions with brown necrotic centers surrounded by a red-yellow coloration, corresponding on the abaxial side to lesions containing brown-orange aecia, producing aeciospores, surrounded by a dark red-ored instance of G. yamadae causing Japanese apple rust in Ohio. Because infected trees tend to be highly symptomatic, this disease poses a significant threat to the nursery and landscape industries as it can decrease the market value of ornamental varieties and affect yield and crop quality in varieties used for fruit production.Grapevine virus H (GVH) is a member of the genus Vitivirus in the family Betaflexiviridae (subfamily Trivirinae, order Tymovirales) that infects grapevine (Candresse et al., 2018). GVH was first identified in a symptomless grapevine of an unknown cultivar from Portugal in 2018 (Candresse et al. 2018), and since then the virus has been reported only from California (Diaz‑Lara et al. 2019). Several vitiviruses have been detected in Greek vineyards (Avgelis and Roubos 2000; Dovas and Katis 2003a; 2003b; Panailidou et al. 2019; Lotos et al. 2020), but no information was available on the presence of GVH. In the fall of 2020, in order to investigate the virome of a commercial vineyard of the cultivar Assyrtiko in northern Greece, a composite sample was made of leaves and petioles from nine vines exhibiting leafroll disease symptoms. Total RNA was extracted from the composite sample according to the protocol of White et al. (2008) and subjected to rRNA depletion, library construction (TruSeq Stranded Total RNA kit),equencing (MW460005) was 97.5% identical to the nucleotide sequence of the corresponding GVH-like de novo contig (GeA-9) from HTS analysis and it shared 97.2% nt identity with GVH sequences reported from Portugal and USA, respectively (NC_040545 and MN716768), confirming the presence of GVH in the tested samples. This is the first report of GVH in grapevine in Greece, thus further increasing the number of vitiviruses known to infect Greek vineyards and also expanding the number of geographic locations in which GVH is recorded so far.
