ABSTRACT
Penile fractures happen when the tunica albuginea is forcefully torn during intense sexual activity or vigorous masturbation. Gunshot-induced cases are extremely rare. Diagnosis, often requiring surgical exploration, poses challenges due to the condition's rarity and severity. We report a complex case of a patient with multiple gunshot wounds, highlighting the need for a multidisciplinary approach for abdominal and genitourinary regions. A 24-year-old male presented to the emergency department with multiple gunshot wounds to the anterior thoracic and abdominal walls, inguinal region, penis, and lower extremities. Despite multiple gunshot wounds, the patient maintained hemodynamic stability during physical examination. No imaging study was performed since surgical management was decided due to the presence of hematemesis. During exploratory laparotomy, a 2 cm stomach lesion was found and repaired by the general surgery team. Urology then addressed genital trauma, identifying and fixing a 1 cm tunica albuginea defect in each corpora cavernosa, achieving bilateral penile fracture repair. The patient was discharged after eight days of hospitalization, with adequate oral intake and urinating. Fifty-two days later, he persists with mild erectile dysfunction (International Index of Erectile Function-5 score: 17 points). This unique case involving a gunshot-induced penile fracture alongside abdominal and several other injuries was successfully managed through a multidisciplinary approach. As these lesions are rare, prompt treatment with standardized surgical procedures for civilian cases is crucial for optimal outcomes.
ABSTRACT
Neural progenitor cell (NPC) transplantation is a promising therapeutic strategy for replacing lost neurons following spinal cord injury (SCI). However, how graft cellular composition influences regeneration and synaptogenesis of host axon populations, or recovery of motor and sensory functions after SCI, is poorly understood. We transplanted developmentally-restricted spinal cord NPCs, isolated from E11.5-E13.5 mouse embryos, into sites of adult mouse SCI and analyzed graft axon outgrowth, cellular composition, host axon regeneration, and behavior. Earlier-stage grafts exhibited greater axon outgrowth, enrichment for ventral spinal cord interneurons and Group-Z spinal interneurons, and enhanced host 5-HT+ axon regeneration. Later-stage grafts were enriched for late-born dorsal horn interneuronal subtypes and Group-N spinal interneurons, supported more extensive host CGRP+ axon ingrowth, and exacerbated thermal hypersensitivity. Locomotor function was not affected by any type of NPC graft. These findings showcase the role of spinal cord graft cellular composition in determining anatomical and functional outcomes following SCI.
