Background: Most injuries observed in victims of lightning strikes can be explained by electrothermal phenomena. Blast penetrating injuries caused by a lightning-strike-induced explosion of a nearby structure are rarely reported.
Case Presentation: Here reported is the case of a patient with numerous mixed injuries caused by a lightning strike, including deep lacerations of both hips and thighs with rock fragments embedded in the wounds. Surgical removal of rock fragments from deep areas of the right hip and right lower leg was necessary. The cause of the formation of rock missiles was the lightning-strike-induced explosion of rock. Rapid evaporation of water enclosed in rock crevices was presumably the main force underlying the explosion.
Conclusion: Blast penetrating injuries should be considered and excluded in all patients struck by lightning, particularly when occurring in rocky terrain. The diagnosis and treatment of such injuries can be difficult and require special preparation.

Trauma and burn injuries often present with multiple complications, necessitating a coordinated, multidisciplinary approach to management. This case series reviews the outcomes and challenges of treating high-risk trauma and burn patients, with a focus on complex polytrauma, alcohol withdrawal, high-voltage electrical injuries, and lightning strikes. Each case underscores the importance of early intervention, multidisciplinary team involvement, and individualized treatment protocols for improving patient outcomes in critically injured burn victims.

Due to the complex and uncertain physics of lightning strike on carbon fiber-reinforced polymer (CFRP) laminates, conventional numerical simulation methods for assessing the residual strength of lightning-damaged CFRP laminates are highly time-consuming and far from pretty. To overcome these challenges, this study proposes a new prediction method for the residual strength of CFRP laminates based on machine learning. A diverse dataset is acquired and augmented from photographs of lightning strike damage areas, C-scan images, mechanical performance data, layup details, and lightning current parameters.

Lightning represents the primary threat to power grids, with approximately 80% of natural occurrences being multi-lightning strikes, which have been extensively studied and confirmed to pose even more severe hazards. Hybrid DC circuit breakers (DCCBs) exhibit promising application prospects due to their superior interruption performance. During multi-lightning strikes, lightning intrusive waves pose a greater threat to the insulation of equipment such as hybrid DC fuses, fast mechanical switches, and insulated gate bipolar transistors.

Cardiac disease in young children can be unrecognized until symptoms are unmasked by a precipitating event, such as an infection. We present a case of anomalous left coronary artery from the pulmonary artery causing clinically significant disease in a four-month-old male with concomitant mitral regurgitation and pulmonary coccidioidomycosis who required modification of his surgical management due to the infection. This case highlights how timely diagnosis and perioperative management and recovery can be affected by concurrent infections in patients with congenital heart disease.
