Small angle neutron scattering (SANS) data are reported from a system that models the contamination of a clay/organic matter soil from a fuel spillage. The soil was represented as an aqueous dispersion of the synthetic clay mineral Laponite coated with lysine, and the contaminant was a representative jet fuel, quadricyclane, mixed with the detergent cetyltrimethylammonium bromide (CTAB). The ad...

Gallstone spillage is a common intraoperative event during laparoscopic cholecystectomy (LC). Patients present months to years with nonspecific symptoms after the original procedure. The complications of retained peritoneal gallstones are infrequent. Having a high index of suspicion is the key to early diagnosis. Every effort should be made to remove spilled gallstones at the index operation to...

Ectopic recurrence of craniopharyngioma is extremely rare. Two mechanisms have been proposed to explain this phenomenon: direct implantation along the previous surgical tract and dissemination via cerebrospinal fluid (CSF). We present a case of ectopic recurrence along the surgical route after transcranial gross total resection (GTR) of primary tumor. Cystic tumor seems to be a risk factor of e...

This paper describes an outbreak of dermatitis among stevodores at a port handling cement. The cement was imported in bags, and because of breakage, there was much spillage. It was also hot and dusty inside the hatch of the ship, and some of the stevodores worked bare-bodied. Cases of dermatitis began to appear in January 1983 and reached a peak in April 1983, gradually subsiding over the next ...

Fast decoding algorithms are described for a number of established coded aperture systems. The fast decoding algorithms for all these systems offer significant reductions in the number of calculations required when reconstructing images formed by a coded aperture system and hence require less computation time to produce the images. The algorithms may therefore be of use in applications that req...

We report two similar thoracoabdominal complications we encountered due to retained gallstones after cholecystectomy. These patients had had an open cholecystectomy after a failed laparoscopic attempt, with spillage of gallbladder debris intraoperatively. They were admitted more than 12 months later with subdiaphragmatic abscesses. Attempted computerized axial tomography (CT) guided drainage of...

Spillage of gallstones (6-40%) are common during laparoscopic cholecystectomy. Development of intraperitoneal and perihepatic abscesses are relatively rare (<0.1%). However, it may pose a diagnostic dilemma mimicking intra-abdominal tumor due to their similar radiologic appearance. CASE REPORT We present a 57-year-old woman with history of cholecystectomy 8 years prior who presented with a su...
