Nonsteroidal anti-inflammatory drugs are a common cause of intestinal injury. A variety of NSAID-induced injuries may occur including ulcers, erosions, colitis, strictures, and diaphragm disease. Diaphragm disease refers to the development of multiple thin, concentric, stenosing strictures in the intestine. Strictures occur most often in the midintestine and are thought to be pathognomonic of N...

NMA Williams, DFL Watkin Summary Intraperitoneal free gas seen radiologically as air under the diaphragm nearly always indicates a perforated abdominal viscus that requires surgical intervention. Rarely, however, the presence of a pneumoperitoneum may not indicate an intra-abdominal perforation and thus may not require laparotomy. Such a situation is termed spontaneous or nonsurgical pneumoperi...

For a photon field of size 20x20cm in a telecobalt machine with ‘Source Diaphragm Distance (SDD)’ of 45 cm, DWTC is designed to provide compensation at ‘source skin distance (SSD)’ of 80 cm. A jig stand with 3 acrylic perforated sheets kept together at specified gaps allow required radial divergence of the metal spokes on equally spaced grid. Dose compensator could be fabricated by a tray mount...

Intraperitoneal free gas seen radiologically as air under the diaphragm nearly always indicates a perforated abdominal viscus that requires surgical intervention. Rarely, however, the presence of a pneumoperitoneum may not indicate an intra-abdominal perforation and thus may not require laparotomy. Such a situation is termed spontaneous or nonsurgical pneumoperitoneum. In this review, we explor...

A congenital diaphragm is an extremely rare cause of duodenal obstruction in adult life and is usually not diagnosed before operation. Halka et al. ' were the first to report the endoscopic features of this deformity, describing a "cervix sign" characterized by a narrow nipple-shaped lumen with circumferential cuffing of the duodenal muco~a at the apex of the bulb giving the appearance of a cer...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2012008459 DESCRIPTION A 55-year-old woman presented to the emergency department with acute upper abdomen pain and vomiting for 2 days. She had no history of duodenal ulcer. On examination she appeared unwell and hypotensive. Abdominal examination revealed mild guarding with no rebound. Plain abd...

BACKGROUND A diaphragmatic hernia is defined as a defect in part of the diaphragm through which abdominal contents can protrude into the thorax. It may be congenital or acquired. In this case report, we aim to demonstrate a congenital diaphragmatic hernia in an adult marfanoid patient which required emergency treatment CASE PRESENTATION A 43 year old woman was admitted with classical appendic...

  Background Recent studies indicate increased serum amylase in children with acute appendicitis. The objective of the current study was to determine the diagnostic accuracy of raised serum amylase level in prediction of perforated appendicitis in children with acute appendicitis. Materials and Methods In this cross-sectional study, 61 children (aged 3 to 15 years) who underwent appendectomy su...

Polymeric drug delivery systems usually deliver drugs by diffusion with an initial burst of release followed by a slower prolonged release phase. An optimal system would release exact doses of drugs using an on-demand external actuation system. The purpose of this study was to design and characterize a novel drug-delivery device that utilizes near infrared (NIR 800 nm) laser-actuated drug relea...
