    We describe herein an autopsy case involving fatal hemorrhagic shock due to idiopathic sigmoid colonic intramural hematoma rupturing into the abdominal cavity. Antemortem computed tomography revealed a mass lesion in the sigmoid colon and a large amount of hemoperitoneum. On forensic autopsy, intramural hematoma of the sigmoid colon with ruptured serosa was identified, while the mucosa remained intact. Microscopically, hematomas were apparent, mainly in the muscularis propria. We diagnosed the cause of death as hemorrhagic shock due to idiopathic intramural hematoma of the sigmoid colon rupturing into the abdominal cavity. Although the patient had been receiving peritoneal dialysis, no relationship was identified between dialysis catheters and sigmoid colon intramural hematoma rupture. On computed tomography, the mass lesion was initially considered a submucosal neoplastic lesion or endometriotic lesion. Intramural hematoma should be considered as a differential diagnosis.

    The number of diatoms detected in the kidneys and liver varies considerably when comparing various reports, but the reason remains unclear. We previously showed that the reuse of Kjeldahl flasks is susceptible to generating false positives; false-positive results were observed in 17 of 60 tested flasks, and a maximum of 290 diatoms were detected. Furthermore, these data suggested that the number of diatoms in kidney and liver tissue may be much lower than previously thought. Therefore, only new Kjeldahl flasks were used to perform diatom tests on 80 autopsy cases (drowning and non-drowning victims) in this study. When combined with the 20 cases in a previous study, a total of 100 cases were analyzed. Four grams of lung, 10–30 g each of kidney and liver, 10 mL of blood, and 50–100 mL of water (discovery site) were examined. A large number of diatoms (n = 400) were found in organs other than the lungs in only 1 of 56 cases of suspected drowning (excluding cases of suspected drowning in baths). Together with the previous 20 cases, this single case represented only 1 of 76 cases (1.3 %). In closed organs and blood samples, 3 diatoms were found in 2 of 56 victims (3.6 %), and 1 or 2 diatoms were found in 8 victims (14 %). However, 5 diatoms were found in 1 of 10 bathtub drowning victims and 12 non-drowning victims (4.5 %), and 1 or 2 diatoms were found in 6 victims (27 %). Moreover, 1 or 2 diatoms were found in negative control flasks in 3 of 80 victims (3.8 %). The results showed that distinguishing false-positive results is difficult when a small number of diatoms are found in the kidneys and liver. Thus, the presence of diatoms in closed organs and blood seems to be unreliable as evidence of death by drowning, at least in the water environments in our region (freshwater areas: 23–26,000 diatoms/mL, median 200 diatoms; brackish water areas: 26–1200 diatoms/mL, median 210 diatoms; seawater area: 2–1000 diatoms/mL, median 24 diatoms). These results also reconfirmed that the reuse of flasks is the most important cause of false positives. Conversely, the presence of a large number of diatoms in lung samples (1–850,000 diatoms/g lung tissue; median (right lung): 440 diatoms, (left lung): 320 diatoms) is very informative and is an effective diagnostic aid in many cases.

    An autopsy case involving a child showing various shapes of tramline bruises caused by a single weapon is described. On autopsy, multiple tramline bruises in different orientations were found, mainly on the back. Shapes of the tramline bruises were variable, including linear, arcuate, nodular, hook-like, and hook-like with a knot at the end. Due to the presence of severe subcutaneous hemorrhages and the absence of other potentially fatal injuries or diseases, we determined the cause of death to be traumatic shock. Microscopically, of the many tramline bruises, characteristic hemorrhages were observed on the right abdominal and left lumbar regions. Those hemorrhages were observed in the dermis, corresponding to macroscopic tramline bruises. Hemorrhage was also observed in the subcutis, corresponding to the pallor of the outer surface. The mechanisms by which tramline bruises occurred in the dermis and subcutis in this case are discussed with reference to the literature. We also propose subcutaneous and intradermal hemorrhagic types of tramline bruising.
