Comparison of Factors Associated With Agitation Among Youngest-Old, Middle-Old, and Oldest-Old Hospitalized Patients Referred to the Psychiatric Department / 정신신체의학

Objectives@#：In this study, elderly hospitalized patients aged 65 years or older who were admitted to a university hospital and referred to the department of psychiatry were classified into youngest-old, middle-old, and oldest-old. It was conducted to find out what factors contribute to the agitation pattern by age group, wheth-er there is a difference in the factors, and whether there is a difference in the severity of the agitation pattern. @*Methods@#：From July 1, 2021 to December 31, 2021, the medical records of patients aged 65 years or older who were referred to the department of psychiatry were retrospectively reviewed. Age, gender, route of hospitalization, department of referral, reason for referral, treatment method, presence of internal and surgical diseases, and hematological test data were investigated. @*Results@#：There was a significant correlation with the RASS score in cases of surgery referral and high CRP levels for youngest-old aged 65 to 74 years, in cases of surgery referral, dementia and hyponatremia for middleold aged 75 to 84 years, in case of dementia for oldest-old aged 85 years old or older. In addition, there were differences in the severity of agitation patterns between age groups. @*Conclusions@#：As the age group increases, the agitation of delirium patients becomes more severe, and vari-ous factors contributing to the agitation pattern also differ by age group. Therefore, when treating elderly pa-tients with delirium, attention should be paid to factors that may affect agitation depending on age.

A Forensic Entomology Case Estimating the Minimum Postmortem Interval Using the Distribution of Fly Pupae in Fallow Ground and Maggots with Freezing Injury / 대한법의학회지

Forensic entomology investigates postmortem interval (PMI) estimation using insect evidence. We estimated the minimum PMI of a putrefied male cadaver using pupae in the soil and maggots found in the body. Most of the maggots, collected during the autopsy, were postfeeding third instar larvae with empty crop contents, which developed freezing injuries when the cadaver was placed in the freezer. Pupae in the soil were collected 45 days after the discovery of the body. DNA barcoding revealed that most pupae and maggots were Chrysomya pinguis, with a few exceptions. The minimum PMI was estimated at 10 days before the discovery time based on the scene investigation, maggot developmental stage, distribution of pupae moving away from the body toward pupariation sites, DNA barcoding results, and weather information. To reduce the gap between the minimum and maximum PMI values, complete entomological evidence collection should be conducted at the time of discovery.
