Introduction: Electrical injuries can cause deep tissue damage with life-threatening complications, yet gastrointestinal perforation remains extremely rare. We present an unusual case of colonic perforation following high-voltage electrocution. Case Presentation: A 32-year-old male sustained a high-voltage electrical shock while climbing an electric fence. He presented with diffuse abdominal pain and burn injuries at the wrist and knee. Imaging showed pneumoperitoneum. Exploratory laparotomy revealed a transverse colon laceration and an ileal perforation. Surgical repair with colostomy and wrist aponeurotomy were successfully performed. The patient recovered well with no postoperative complications. Conclusions: This case underscores the importance of maintaining high suspicion for internal visceral injuries in electrical trauma patients, regardless of superficial burn severity. Early diagnosis and prompt surgical intervention are key to favorable outcomes.

Background: Nightmare proneness has been associated with insomnia beyond nightmare frequency and neuroticism. The present study examined physiological hyperarousal as a potential process contributing to this relationship. Methods: Participants were 209 adults recruited from a university participant pool and an online community sample. Participants completed self-report measures of nightmare proneness, insomnia, physiological hyperarousal, nightmare frequency, neuroticism, and trauma symptoms. Hierarchical regression and indirect-effect analyses were conducted. Results: After controlling for recruitment source, gender, nightmare frequency, neuroticism, and trauma symptoms, nightmare proneness explained an additional 6.5% of the variance in insomnia. Physiological hyperarousal accounted for an additional significant 2.2% of variance beyond nightmare proneness. Nightmare proneness showed a significant indirect association with insomnia through physiological hyperarousal. However, nightmare proneness maintained an direct association with insomnia outside physiological hyperarousal. Conclusion: Physiological hyperarousal may represent one process contributing to the relationship between nightmare proneness and insomnia but does not fully account for this association. The findings support conceptualizing nightmare proneness and physiological hyperarousal as related but non-redundant factors associated with insomnia.

Non-Hodgkin lymphoma (NHL) comprises a heterogeneous group of lymphoid malignancies with clinical behaviour ranging from indolent to highly aggressive. These neoplasms arise from lymphoid cells at different stages of differentiation, and their biological characteristics reflect their cellular origin. Intraoral NHL is uncommon and may involve either the jaw bones or the soft tissues of the oral cavity. We report the case of a 54-year-old man who presented with persistent buccal space swelling following extraction of the mandibular right second molar (tooth 47) for presumed odontogenic infection. Despite antibiotic therapy, the swelling progressively increased in size and was associated with the development of lower-lip paresthesia. An initial clinical diagnosis of antibioma was made; however, the persistence and progression of the lesion prompted further investigation. Histopathological examination and immunohistochemical analysis established a diagnosis of diffuse large B-cell lymphoma (DLBCL). This case highlights the importance of considering malignant disease in the differential diagnosis of persistent or progressive orofacial swellings, particularly when presumed odontogenic lesions fail to respond to appropriate treatment or are accompanied by neurosensory disturbances.
