Chronic pancreatitis in children: treat like an adult?

A 15-year-old boy with a medical background of obesity, familial hyperlipidemia and acute recurrent pancreatitis, presented to emergency department reporting a 3-day course of periumbilical abdominal pain and nausea. Pain was noticed on epigastric palpation. Laboratory evaluation revealed leucocytosis, neutrophilia and pancreatic enzymes elevation more than three times the upper limit of normal. An acute recurrence of pancreatitis was diagnosed, was admitted to the hospital, being discharged after 5 days. Four days after, he was readmitted because of symptoms recurrence. Elevation of transaminases, gamma-glutamyltransferase (GGT) and direct bilirubin were noticed. Pancreatic enzymes still elevated but lower than in the previous episode. An endoscopic ultrasound revealed a Wirsung with a cephalic stricture and diffuse structural abnormalities suggestive of chronic pancreatitis. The patients was submitted to endotherapy with several sessions of endoscopic retrograde cholangiopancreatography including stenting and pancreatoscopy with marked clinical and imaging improvement. A genetic variant was identified.info:eu-repo/semantics/publishedVersio

Electronic doping of graphene by deposited transition metal atoms

We perform a phenomenological analysis of the problem of the electronic doping of a graphene sheet by deposited transition metal atoms, which aggregate in clusters. The sample is placed in a capacitor device such that the electronic doping of graphene can be varied by the application of a gate voltage and such that transport measurements can be performed via the application of a (much smaller) voltage along the graphene sample, as reported in the work of Pi et al. [Phys. Rev. B 80, 075406 (2009)]. The analysis allows us to explain the thermodynamic properties of the device, such as the level of doping of graphene and the ionisation potential of the metal clusters in terms of the chemical interaction between graphene and the clusters. We are also able, by modelling the metallic clusters as perfect conducting spheres, to determine the scattering potential due to these clusters on the electronic carriers of graphene and hence the contribution of these clusters to the resistivity of the sample. The model presented is able to explain the measurements performed by Pi et al. on Pt-covered graphene samples at the lowest metallic coverages measured and we also present a theoretical argument based on the above model that explains why significant deviations from such a theory are observed at higher levels of coverage.Comment: 16 pages, 10 figure

Losses and Dry Matter Recovery of Pioneiro Grass (\u3cem\u3ePennisetum purpureum\u3c/em\u3e Schumach) and Maize Silages in Mixtures

Forages ensiled with high moisture content produce increased quantities of effluents losing highly digestible nutrients (McDonald 1981). The ensilage process usually involves gaseous and effluent losses which are strictly related to the moisture content of the plants used for conservation. The addition of materials with high dry matter content and materials which improve the fermentation pattern has been an alternative to reduce these effluent losses. The maize plant and maize grain, by their physical and fermentative characteristics, may represent alternatives to reduce the losses in the process (Anaya-Ortega et al. 2009). This work was carried out with the aim to evaluate the effect of whole plant maize and maize grain addition to silages of Pioneiro grass as way to control dry matter losses
