Individual identification using the RapidHIT™ ID system for forensic samples.

The RapidHIT™ ID system produces GlobalFiler™ analysis results after a short operating time. This device is effective because it automatically extracts DNA from oral mucosal cells or from blood stains and saliva collected at a crime scene, with subsequent polymerase chain reaction performed to produce a DNA profile. Two types of dedicated cartridges are available for RapidHIT™ ID: the RapidHIT™ ID ACE GlobalFiler Express sample cartridge for oral cells and other samples and the RapidINTEL™ sample cartridge for minute samples, such as blood stains. Previously validated specimens include oral mucosa cells and blood stains left at crime scenes. There have been no reports of blood and nail clipping samples collected from the postmortem bodies at the time of death. This report summarizes the results of using the RapidHIT™ ID system by collecting a variety of actual forensic samples from postmortem bodies at different stages of decomposition, which were subsequently analyzed using these cartridges.

Extensive gastric necrosis secondary to acute gastric dilatation: A case report.

We report a case of sudden death in a patient who developed extensive gastric necrosis secondary to acute gastric dilatation. A 36-year-old man with mental retardation (but without difficulties in activities of daily living), developed an illness after a meal out with friends, necessitating 3 hospital visits. He returned home after receiving drug therapy; however, his condition deteriorated, and he was transferred to our hospital via ambulance. Whole-body computed tomography performed upon admission revealed gastric dilatation. A stomach tube was inserted, and 2000 mL of gastric aspirate was obtained. The patient died approximately 5 h later despite receiving treatment. Autopsy revealed 1000 mL of gastric contents and extensive gastric necrosis. He was diagnosed with extensive gastric necrosis secondary to acute gastric dilatation.
