Association between sudden unexpected deaths in bathtubs and ambient temperature among elderly Japanese adults: a time-series regression study
Japanese elderly adults have extremely high mortality associated with bathtub-related drowning [1]. Based on postmortem examination, it was revealed that approximately 55% of individuals who experienced sudden bath-related deaths between 2009 and 2011 in Tokyo had circulatory diseases, and more than 90% of these deaths in both sexes were in elderly adults older than 60 years [2]. Although previous studies have addressed cardiac arrest [3] or other symptoms (falling, loss of consciousness, stroke, and others) and accidents [4,5], including deaths not involving a bathtub or showering, many Japanese studies have focused on su...

Micro-computed tomography of false starts produced on bone by different hand-saws
The tools used in post-mortem dismemberment produce characteristic witness marks on the body of the victim, commonly defined tool marks. The macroscopic and microscopic analysis of tool marks on bones plays a crucial role in forensic anthropology and pathology, providing useful information about the instrument used to cause them [1]. When saws are used to cut bones, they often leave specific saw marks, known as “false starts”, which occur when the blade of the saw, during a stroke, hits the surface of the bone briefly and then restarts from another point, close to the initial point of cut.

A rare autopsy case of traumatic rhabdomyolysis associated with intermittent assault
Rhabdomyolysis, or the dissolution of skeletal muscle, is characterized by the leakage of intramyocellular substances such as myoglobin, electrolytes, and other sarcoplasmic proteins into the circulation [1–3]. The development of rhabdomyolysis has many causes, including trauma, excessive muscular activity (e.g., exercises and seizures), prolonged immobilization, muscle ischemia, infection, excess body heat (e.g., heat stroke and malignant syndrome), metabolic and electrolyte disorders, drugs and toxins, and genetic defects [4–9].
