Use of laser-scanning confocal microscopy in the detection of diagenesis in bone

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM.

Fatal penetrating abdominal injury by a metallic projectile

Penetrating abdominal injury is often a life-threatening condition, which is mainly associated with inflicted injuries. Fatal self-inflicted sharp force abdominal injuries too have been reported in the literature. Inadvertent penetrating abdominal injuries are a rarity and are caused by sharp objects of low-velocity and often nonmissile-type. A 27-year-old male factory worker was brought dead to the emergency department with an alleged history of sustaining abdominal injury by a sharp metal projectile while working on a metal cutting grinder. Autopsy observations were consistent with the history of inadvertent penetrating injury. Our case reports a fatal missile-type inadvertent sharp force trauma over the abdomen with intestinal perforation, a relatively uncommon scenario in occupational/workplace settings. The present case report describes the significance of the death scene visit and corroborating the medical findings with investigating agencies. This case further emphasizes on the need for adopting proper safety measures at the workplace.
