Kudo's pit pattern classification for in vivo optical diagnosis and discrimination of advanced colorectal polyps.

Objective: Colonoscopy is currently the basic diagnostic tool for the large intestine. The size of lesions assessed during the investigation is one criterion for assessing the risk of polyps transforming into colorectal cancer. The techno-logical development of endoscopes and the possibility of direct assessment of lesion's surface during the endoscopic examination and to use appropriate treatment.

Barrier Dispersion-Based Coatings Containing Natural and Paraffin Waxes.

Petroleum, synthetic, and natural waxes have been used as hydrophobic bases for dispersions intended for use as barrier coatings for packaging paper. Oil-in-water dispersions with alkaline pH were prepared by a two-step homogenization procedure containing paraffin wax, with various characteristics, the Fischer-Tropsch synthesis product or beeswax. The size of the dispersed particles determined by dynamic light scattering depended on the type of hydrophobic base used and was in the range of 350-440 nm.

Impact of shredding degree on papermaking potential of recycled waste.

The properties of paper products depend on the structure of the cellulose fibres therein. Although fibre properties in virgin pulps can be modified by a refining process, this is more difficult in pulp from recovered fibre, particularly waste from office shredders that tend to shorten fibres during shredding. The shorter fibres in shredded paper make it difficult to easily reconstitute them into high-quality paper products.

Factors influencing an eruption of teeth associated with a dentigerous cyst: a systematic review and meta-analysis.

Background: A dentigerous cyst (DC) is a pathology embracing the crown of an unerupted tooth at risk of malignant transformation. The causal tooth is usually removed together with the cyst. However, if there are orthodontic contraindications for extraction, two questions arise.

Influence of lignin content in cellulose pulp on paper durability.

Paper degradation on a macroscopic scale is characterised primarily by yellowing, an increase in brittleness, and other destructive changes caused by the hydrolysis of glycoside bonds and oxidation reactions. Until now, lignin has been believed to cause these changes. However, contemporary analysis has not confirmed this assumption and has attributed low paper resistance to ageing with acidification owing to the production in acid environments that involve aluminium sulfate.

Endoscopic ultrasound-guided ethanol ablation of insulinoma.

Not required for Clinical Vignette.

Contribution of Hydrogen Bonds to Paper Strength Properties.

The objective of this work was to investigate the influence of hydrogen bonds between fibres on static and dynamic strength properties of paper. A commercial bleached pinewood kraft pulp was soaked in water, refined in a PFI, and used to form paper webs in different solvents, such as water, methanol, ethanol, n-propanol and n-butanol, to determine the effect of their dipole moment on static and dynamic strength properties of resulting paper sheets. Paper which was formed in water, being the solvent of the highest dipole moment among the tested ones, showed the highest breaking length and tear resistance.

The role of endoscopic ultrasonography in endoscopic debridement of walled-off pancreatic necrosis--A single center experience.

Background: In recent years the significance of endoscopic ultrasonography (EUS) has increased. In our center we have also performed EUS-guided cystostomy since 2011. Earlier we had performed this procedure without EUS.

Dental anomalies in the incisor-canine region in patients with cleft lip and palate - literature review.

Tooth disorders in the anterior region of the maxilla are very common among patients with cleft lip, alveolar bone and palate. The authors concentrate on dental disorders, erupting problems and root development, specifying dental anomalies - especially regarding the lateral incisor, central incisor and canine. Disorders may relate to the shape of the tooth, its location, size, number and they can be considered separately or together.

Endoscopic drainage/debridement of walled-off pancreatic necrosis--single center experience of 112 cases.

Background: Endoscopic drainage of the pancreatic pseudocysts has been accepted as a valid alternative to surgical and percutaneous drainage. Endoscopic treatment of the symptomatic walled-off necrosis was not, however, univocally accepted by all authors.

The Aim: The aim of this study was to assessed the effectiveness and safety of the endoscopic drainage of walled-off necrosis.

Endoscopic submucosal dissection of gastric ectopic pancreas.

Patients with gastric tumors usually present with symptoms of discomfort or pain in the epigastrium, regurgitations, nausea, vomiting or melena. Treatment options include open and laparoscopic total or partial gastrectomy and recently endoscopic mucosal resection. A case of successful endoscopic submucosal dissection is described with the unusual pathological finding of heterotopic pancreatic tissue forming a gastric tumor.

Routine brush cytology and fluorescence in situ hybridization for assessment of pancreatobiliary strictures.

Background: The specificity of brush cytology for detection of malignant pancreatobiliary strictures is high, but its sensitivity is moderate. Fluorescence in situ hybridization (FISH) can be used to detect chromosomal aneuploidy in biliary brushing specimens, and, according to some reports, it may improve the sensitivity of routine cytology.

Objective: To assess the role of routine cytology and FISH in detection of malignant pancreatobiliary strictures.

Sclerosing cholangitis associated with retroperitoneal fibrosis: a case of multisystem fibroinflammatory disorder.

Introduction: Retroperitoneal fibrosis is a fibroinflammatory disease of unknown etiology that can be associated with other fibroinflammatory disorders. Lately, there have been several reports showing that retroperitoneal fibrosis is a manifestation of IgG4-related sclerosing disease, which often presents as autoimmune pancreatitis.

Case Report: This report shows the case of IgG4-related sclerosing cholangitis associated with retroperitoneal fibrosis independent of autoimmune pancreatitis.
