Fast gas chromatography of explosive compounds using a pulsed-discharge electron capture detector

The detection of a mixture of nine explosive compounds, including nitrate esters, nitroaromatics, and a nitramine in less than 140 sec is described. The new method employs a commercially available pulsed-discharge electron capture detector (PDECD) coupled with a microbore capillary gas chromatography (GC) column in a standard GC oven to achieve on-column detection limits between 5 and 72 fg for the nine explosives studied. The PDECD has the benefit that it uses a pulsed plasma to generate the standing electron current instead of a radioactive source. The fast separation time limits on-column degradation of the thermally labile compounds and decreases the peak widths, which results in larger peak intensities and a concomitant improvement in detection limits. The combination of short analysis time and low detection limits make this method a potential candidate for screening large numbers of samples that have been prepared using techniques such as liquid-liquid extraction or solid-phase microextraction.     

Adult Hirschsprung's disease diagnosed during forensic autopsy

We report a case of fatal Hirschsprung's disease (HD) discovered at autopsy. A 20-year-old man collapsed at home. Emergency medical personnel found him in cardiac arrest and all resuscitative efforts failed. He had a past history of chronic constipation since infancy. Forensic autopsy revealed a megacolon full of gas and stools. Microscopic examination showed absence of ganglion cells in a short segment of the rectum and enterocolitis in the left and transverse colon. HD is rarely described in adults. In many cases, patients complained of constipation since infancy but the affection remained misdiagnosed. The relative good tolerance of the disease is usually due to a short aganglionic bowel segment. Enterocolitis is a frequent and severe complication of HD in children but is rarely described in adults. This case suggests the importance of HD diagnosis in childhood in order to avoid fatal complications with forensic consequences.     

Safeguarding adults and mass marketing fraud – Perspectives from the police,trading standards and the voluntary sector

Despite the growing awareness of mass marketing fraud (MMF) in the financial abuse of vulnerable older people, little empirical research has been undertaken in this area. This paper is one of the first to consider the perspectives of a range of professionals who work with victims of mass marketing fraud and financial crime. MMF is a growing threat in the financial abuse of older people, and is increasingly recognised as a concern for professionals involved in supporting and safeguarding vulnerable older people. This paper considers the themes emerging from a small exploratory qualitative study into the perspectives of professionals working to safeguard those at risk of MMF and considers some of the complexities involved in tackling MMF. This involves consideration of the techniques used to groom and lure victims in plausible looking frauds, and the factors that serve to reinforce their sustained involvement in such activity.
