Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

Necrotizing enterocolitis (NEC) is an inflammatory process, characterized by intestinal necrosis of variable extension, leading to perforation, generalized peritonitis and death. The classical pathogenetic theory focuses on mucosal damage related to a stress induced intestinal ischemia leading to mucosal injury and bacterial colonization of the wall. A more recent hypothesis emphasizes the role of immaturity of gastrointestinal and immune system, particularly of the premature, responsible of bowel wall vulnerability and suffering...

INTRODUCTION AND PURPOSE: The increasing number of patients undergoing hemodialysis and the limited number of access sites have resulted in an increasing number of techniques to maintain vascular access for hemodialysis. Thrombosed arteriovenous (AV) fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definitive AV access loss. The purpose of this study was to review the feasibility and initial results of this novel endovascular treatment of thrombosed AV fistulas with large venous aneurysms...

The last 25 to 30 years have seen enormous advances in imaging techniques for the diagnosis of heart disease (echocardiography, cardiac MRI, CT angiography, etc.). Nevertheless, the first imaging test done in patient with heart disease continues to be plain-film chest X-rays. This economical, widely available technique makes it possible to follow up patients with heart disease and even to assess the severity of disease in some cases. This article explains how to read a chest X-ray systematically and the radiologic signs that make possible to suspect heart disease; it also provides detailed information about the signs of heart failure and the meaning of cardiac calcifications...

Horseshoe kidney is the most common congenital renal fusion anomaly with an incidence of 1 in 400-600 individuals. The most common type is fusion at the lower poles seen in greater than 90% of the cases, with the rest depicting fusion at the upper poles, resulting in an inverted horseshoe kidney. Embryologically, there are two theories hypothesizing the genesis of horseshoe kidney - mechanical fusion theory and teratogenic event theory. As an entity, horseshoe kidney is an association of two anatomic anomalies, namely, ectopia and malrotation...

This case is described of an eleven-month-old infant with lower limbs swelling and the left elbow skeletal malformation following a fall. The radionuclide bone scan was performed to exclude bone infection or congenital skeletal anomaly. The images unexpectedly showed multiple increased radioactive foci throughout the whole body. It was a strong probability of child abuse. All lesions are readily apparent on the following plain film radiographs and MRI.

A 23-year-old woman presented to the emergency department after manually inserting foreign bodies into the urinary bladder through her urethra. A plain abdominal film of the kidneys, ureters and bladder confirmed three radio-opaque densities in the urinary bladder. She was taken to the operating room where cystourethroscopy was performed. At cystoscopy 2 'corn-on-the-cob' skewers and 1 battery were identified but were too large to be retrieved safely with a grasper through the protective sheath. The objects were grasped with a 'sponge-holding forceps' (placed alongside the cystoscope) and extracted one at a time...

Cell-selective delivery and sensitivity to serum nucleases remain major hurdles to the clinical application of RNA-based oligonucleotide therapeutics, such as siRNA. Spider silk shows great potential as a biomaterial due to its biocompatibility and biodegradability. Self-assembling properties of silk proteins allow for processing into several different morphologies such as fibers, scaffolds, films, hydrogels, capsules and spheres. Moreover, bioengineering of spider silk protein sequences can functionalize silk by adding peptide moieties with specific features including binding or cell recognition domains...

Antibody immobilization on polymeric substrates is a key manufacturing step for microfluidic devices that implement sample-to-answer automation of immunoassays. In this work, a simple and versatile method to bio-functionalize poly(methylmethacrylate) (PMMA), a common material of such "Lab-on-a-Chip" systems, is proposed; using the Layer-by-Layer (LbL) technique, we assemble nanostructured thin films of poly(ethylene imine) (PEI) and graphene oxide (GO). The wettability of PMMA surfaces was significantly augmented by the surface treatment with (PEI/GO)5 film, with an 81% reduction of the contact angle, while the surface roughness increased by 600%, thus clearly enhancing wettability and antibody binding capacity...

The wings of insects such as cicadas and dragonflies have been found to possess nanostructure arrays that are assembled from fatty acids. These arrays can physically interact with the bacterial cell membranes, leading to the death of the cell. Such mechanobactericidal surfaces are of significant interest, as they can kill bacteria without the need for antibacterial chemicals. Here, we report on the bactericidal effect of two of the main lipid components of the insect wing epicuticle, palmitic (C16) and stearic (C18) fatty acids...

Scaphoid fractures are the most common carpal bone fracture. Up to 40% of scaphoid fractures can be missed at initial presentation and investigation. Follow-up plain film radiograph has overall poor sensitivity and reliability. MRI has been shown to have an almost 100% sensitivity and specificity and so is the gold standard in scaphoid fracture diagnosis. Additionally, early specialist involvement is recommended. We proposed that following a designated pathway, there would be no significant increase in MRI requests...

BACKGROUND: Ingestion of elemental mercury (Hg0) is considered non-toxic. After massive ingestion, local intestinal complications may develop: retention within appendix is quite frequent but treatment is debated. We describe a case of intentional ingestion of Hg0 requiring multi-step decontamination and prophylactic appendectomy. Case detail: A 19-year-old woman was admitted to ED for abdominal pain. History revealed ingestion of large amount of Hg0 as suicide attempt. To prevent absorption, facilitate elimination, and avoid complications a conservative approach was started...
