Laryngeal teflonoma identified by Fourier-transform infrared microspectroscopy after forensic autopsy: an interesting tool for foreign material identification in forensic cases

Forensic pathologists are sometimes confronted with microscopic foreign bodies mixed in with soft tissues surrounding wounds and which are thus difficult to identify. This identification, however, could be primordial in investigating a crime and in determining the weapon used. A case of a fatal respiratory distress syndrome due to conjoining suicidal drug intoxication and laryngeal obstruction by a voluminous foreign body giant cell granuloma is presented. The classical histological examination showed exogenous particles in the vocal cord tumor with birefringent qualities. Their analysis with Fourier-Transform infrared (FTIR) spectrometry coupled with infrared microscope allows the determination of their chemical nature as polytetrafluoroethylene and to the diagnosis of teflonoma. This case report put the emphasis on the forensic interest of the FTIR imaging.     

Macroscopic, histological and toxicological aspects of early Gammarus pulex scavenging

Two cases of scavenging postmortem freshwater shrimps (Gammarus pulex) are presented. We report the two first illustrated observations of cutaneous postmortem injuries inflicted by a G. pulex population, a small freshwater crustacean, on two non putrefied drowning victims, and we describe their particular histological features and their potential in forensic investigations.     

Congress and the political expansion of the U.S. districts courts

Expanding the number of U.S. district judgeships is often justifiedas a response to expanding caseloads. Increasing judgeshipsduring unified government, however, allows Congress and thePresident to engage in political (patronage and ideological)control of the federal district courts. This paper examinesempirically the relative importance of caseload pressure andpolitical motives for Congress to expand the number of federaldistrict judgeships. We demonstrate that politics dominatesthe timing of judgeship expansion in the U.S. District Courts.We also show that both politics and caseload affect the actualsize of those timed expansions. In particular, we find thatbefore 1970, Congress seemed to have strong political motivationsfor the size of an expansion. After 1970, Congress became muchmore attentive to caseload considerations.
