1/8. Implantable cardioverter defibrillator-an unusual case of inappropriate discharge during showering.

    The evolution of diagnostic information provided in implantable cardioverter defibrillators (ICDs) has paralleled the advances in the therapeutic options incorporated in these systems. Contemporary devices are capable of providing recordings of electrical events surrounding all delivered and aborted device therapy. This report presents un unusual case of inappropriate discharge of an ICD, resulting from electromagnetic interference. A transvenous ICD system (Sentry Hot Can 4310 HC, Telectronics Denver, CO), was implanted in a patient with ischemic heart disease due to episodes of ventricular tachycardia refractory to antiarrhythmic treatment. One month post-implant the patient reported two consecutive shocks from the device while showering. The non-physiological cycle length (100 ms) recorded in conjunction to the scenario of the event, raised the suspicion of electromagnetic interference through electrical current leakage in the bathroom, an hypothesis that was subsequently proved. This case report underscores that electromagnetic interference can become hazardous in common daily activities of patients with an ICD.

2/8. The neurological complications of electrical injury: a nursing case management perspective.

    High-energy electrical injury, whether from lightning strike or electrical shock, occurs primarily in the workplace. Neurological dysfunction can be a devastating complication of electrical injury. A review of the literature was undertaken to develop a better understanding of the epidemiology, mechanisms of injury and neuropathology associated with this type of injury. The numerous challenges inherent in the management of these complex cases were illustrated by three case studies.

3/8. Bilateral scapular fractures secondary to electrical shock.

    Fractures of the scapula are rare injuries. Usually the scapula requires a high-energy impact to sustain a fracture. Various fractures have been noted as a result of convulsive seizures. We report bilateral scapular fractures caused by electric shock and discuss their pathomechanical origin.

4/8. The application of a variable-pressure scanning electron microscope with energy dispersive X-ray microanalyser to the diagnosis of electrocution: a case report.

    We describe here a case of accidental electrocution. A 48-year-old male was found dead in his room. At autopsy, there was a current mark on the right thumb and big toe. Histological examination revealed that the skin wound had the characteristics of a current mark, including vacuolation and elongation of the cell nuclei. We could also identify titanium metallization on the skin surface of the current mark using a variable-pressure scanning electron microscope (VP-SEM) equipped with energy dispersive X-ray microanalyser (EDX). The autopsy finding and the subsequent investigation support the conclusion that the cause of his death was electrocution. Our result shows that the VP-SEM with EDX is a useful tool for the forensic diagnosis of electrocution.

5/8. Experimental evaluation of rigor mortis. VII. Effect of ante- and post-mortem electrocution on the evolution of rigor mortis.

    The influence of electrocution on the evolution of rigor mortis was studied on rats. Our experiments showed that: (1) Electrocution hastens the onset of rigor mortis. After an electrocution of 90 s, a complete rigor develops already 1 h post-mortem (p.m.) compared to 5 h p.m. for the controls. (2) Electrocution hastens the passing of rigor mortis. After an electrocution of 90 s, the first significant decrease occurs at 3 h p.m. (8 h p.m. in the controls). (3) These modifications in rigor mortis evolution are less pronounced in the limbs not directly touched by the electric current. (4) In case of post-mortem electrocution, the changes are slightly less pronounced, the resistance is higher and the absorbed energy is lower as compared with the ante-mortem electrocution cases. The results are completed by two practical observations on human electrocution cases.

6/8. Photic maculopathy secondary to short-circuiting of a high-tension electric current.

    A 21-year-old man was exposed accidentally to the flash of a high-tension short circuit. He subsequently developed a yellow-gray foveolar lesion with mild central visual loss. fluorescein angiography demonstrated the area of retinal pigment epithelial disruption and was used to follow its evolution over eight months. The energy level at the retina was estimated at 0.87 Joules/cm2, insufficient to create a thermal burn. Therefore, although the patient suffered thermal facial burns, the foveolar lesion represents a photochemical injury to the retinal pigment epithelium and, hence, is similar to solar retinopathy, eclipse blindness, and arc-welder's retinopathy.

7/8. A late, fatal complication of a high energy thermal injury to the scalp.

    Marjolin's ulcer is an uncommon condition in which malignant transformation occurs in a chronic inflammatory focus. It was originally described in association with a thermal injury, however, its occurrence with protean chronic inflammatory foci has been described. We report the occurrence of and aggressive squamous carcinoma 3 decades after a high voltage electric mark injury to the scalp. This is the first such case described in the literature. The case supportively highlights the role of chronic inflammation and sepsis in epidermal scar cancer development, and it underlines the importance of appropriate wound management initially and expeditious treatment of sepsis and resistant skin ulceration because the malignant behavior of these tumors is aggressive and unpredictable.

8/8. Multiple carpometacarpal dislocations. A case report and review of treatment.

    Carpometacarpal dislocations of the ulnar four joints are rare injuries that are usually associated with high-energy trauma. Given the small number of cases reported, there exists some controversy regarding their optimal management. The case of a 27-year-old man who sustained a dorsal dislocation (without associated fractures) of the ulnar four carpometacarpal joints as a result of a fall from a height is presented. The literature regarding these hand injuries is reviewed, and the need for anatomic reduction and stabilization is discussed.
