Automatic measuring of coronary atherosclerosis from medicolegal autopsy photographs based on deep learning techniques.

A diagnosis of atherosclerotic cardiovascular disease is critical importance in forensic medicine, particularly because severe atherosclerosis is known to be associated with a high risk of sudden death. In South Korea, the assessment of coronary atherosclerosis during autopsy largely depends on the forensic pathologist's visual measurements, which may limit diagnostic accuracy. The objective of this study was to develop a deep learning algorithm for rapid and precise assessment of coronary atherosclerosis and to identify factors influencing the model's prediction of atherosclerosis severity.

Prognostic value of isolated tumor cells and micrometastasis of lymph nodes in invasive urinary bladder cancer.

Introduction: The prognostic significance of nodal micrometastasis and isolated tumor cells (ITC) in urinary bladder cancer (UBC) is unknown. We aimed to evaluate the prevalence, clinical impact, and clinicopathological characteristics of nodal micrometastasis and ITC in UBC.

Materials And Methods: A total of 124 patients with UBC undergoing surgery were investigated.

Calcium chloride poisoning: an autopsy case report and histologic features.

Calcium chloride, which is commonly used in de-icing agents and desiccants, is known for the potential harm it can cause through skin contact, oral ingestion, or intravenous administration. The current paper reports on an autopsy case of a 68-year-old woman who died after ingesting an unknown substance. Histopathological examination revealed coagulative necrosis in the esophagus and ionized blood calcium levels that were significantly higher than normal.

Validation of London Atlas for forensic age estimation in Koreans by comparing with Lee's and Willems' methods.

This cross-sectional study aimed to evaluate the applicability of the London Atlas for age estimation in the Korean population by comparing with Lee's and Willems' methods. Dental ages of 475 orthopantomographs from Korean individuals aged 4-15 years (mean 10.32 ± 3.

Fatal hydrofluoric acid poisoning: histologic findings and review of the literature.

Hydrofluoric acid (HF), the inorganic acid of elemental fluorine, is a highly dangerous substance and death can result from a very small exposure. In addition to local toxicity, HF can trigger fatal systemic reactions by its high affinity for calcium and magnesium. The authors report the autopsy case of a male worker who was exposed to 50% HF while repairing the leakage from an HF tank valve in a semi-conductor washing factory.

Medullary thyroid carcinoma with diabetic ketoacidosis: an autopsy case report and literature review.

Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor of parafollicular C cells. The majority of MTCs occur sporadically, but about 30% of the cases are associated with multiple endocrine neoplasia type 2 (MEN2) syndrome or familial MTC. Generally, MTCs have no clinical manifestation, but infrequently the patients develop symptoms of hypercortisolism by secreting adrenocorticotropic hormone (ACTH) or corticotropin-releasing hormone (CRH).

Proposal of the Autopsy Guideline for Infectious Diseases: Preparation for the Post-COVID-19 Era (abridged translation).

With the rapidly spreading coronavirus disease 2019 (COVID-19) pandemic over the past few months, the world is facing an unprecedented crisis. Innumerable lives have been lost to this novel infectious disease, the nature of which supersedes conventional medical understanding. The COVID-19 pandemic is not just a global health crisis, several aspects of life in the post-COVID-19 era are also being contemplated.
