One of the most challenging issues in forensic pathology is lesion vitality demonstration, particularly in cases of hanging. Over the past few years, immunohistochemistry has been applied to this field with promising results. In particular, protein and transcription factors involved in the apoptotic process have been studied as vitality markers for the ligature mark. This study represents an implementation of our previous studies on ligature mark vitality demonstration. In this study, we evaluated the FOXO3 expression in post-mortem cervical skin samples through an immunohistochemical analysis. To evaluate FOXO3 expression, anti-FOXO3 antibodies (GTX100277) were used. The study group comprised 21 cases, 8 women and 13 men, whereas the control group consisted of 13 cases of subjects who died due to other causes. Decomposition and no clear circumstantial data were exclusion criteria. We found that FOXO3 is decreased in hanging cases compared with normal skin in other causes of death (p-value < 0.05). No differences were seen concerning the type of hanging material (hard or soft), type of hanging (complete or incomplete), and position of the knot. Our results suggest that FOXO3 depletion could be a valid immunohistochemical marker of ligature mark vitality.

To illustrate the potential of mesenchymal stem cell-derived exosomes (MSC-Exos) in mitigating septic lung injury by reducing the excessive formation of neutrophil extracellular traps (NETs), a mouse model of septic lung injury was induced through cecal ligation and puncture (CLP). The mice received intraperitoneal injections of MSC-Exos. Post injection, pathological alterations of the lung tissue were evaluated through HE staining, and the levels of inflammatory markers in each mouse group at various time points were assessed using ELISA kits.

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

Considered the father of surgery, Ambroise Paré was a French military surgeon who creatively improvised and used various surgical instruments during his era. He believed in the principle of evidence-based medicine to treat his patients. He advocated for ligature instead of cauterization in surgeries.

Objectives: This study aimed to assess the effectiveness of four-duct ligation following Botulinum toxin-A injections into the parotid and submandibular glands in pediatric patients with sialorrhea resistant to nonsurgical treatments. Prior research has individually explored either surgical or Botulinum toxin interventions; however, the safety and efficacy of the combined approach to these treatments have yet to be documented.
Methods: Patients were assessed before surgery and 6, 12, and 24 months post-operatively.

Background: Cervical injuries due to hanging have a high mortality rate. Survivors may present for care with subtle symptoms that belie potentially life-threatening injuries to vital structures of the neck.
Case Report: We report a case of a 39-year-old male admitted to the Intensive Care Unit following attempted self-strangulation.
