Multiple nail gun injuries: suicide or homicide?

Nail gun injuries are a forensic problem; it can be difficult to distinguish self-inflicted injuries from accident and homicide instances. This kind of injuries shares some characteristics with both gunshot and puncture wounds. We describe a peculiar case of a man who committed suicide driving nails into his skull using a pneumatic nail gun. Entrance wounds were found on both temporal regions of the head. Reviewing scientific literature, this is the first case in Italy reporting the macroscopic data of bilateral head and brain nail gun injuries during an autopsy. Circumstantial elements were not sufficient to clarify if these lesions were self-inflicted, inflicted by accident, or else. Radiological examination can be helpful to show the exact location of the nails, but it has also its own limitations. We firmly believe that autopsy, especially the head section, is crucial to identify the nature and the extension of these lesions, thus giving us much more information about the mechanism of death and the circumstances in which it occurred.

Low-vacuum negative pressure wound therapy protocol for complex wounds with exposed vessels.

OBJECTIVE: Treating high-risk surgical patients with complex wounds over exposed blood vessels is a challenge. Guided wound healing may be the only treatment possible. Negative pressure wound therapy (NPWT) is not recommended in these cases. The authors challenged these current recommendations and share their preliminary experience. METHOD: The authors adapted a NPWT protocol that uses low-vacuum continuous pressure (-80mmHg) with a silicone sheath and gauze/foam dressing between the wound bed and the device. They monitored the clinical features of patients' wounds to detect bleeding/ischaemia early on. Dressings were changed every 72-96 hours. RESULTS: This protocol was followed in five male patients (aged 23-68 years) with complex wounds over exposed vessels. Two cases were foot crush injuries, one midfoot amputation, one hand self-subamputation and one vascular bypass infection. Comorbidities included monoarterial limbs/stump, severe arteriopathy and psychiatric disorder. The exposed vessels were femoral, radial and ulnar, anterior and posterior tibial arteries and veins. Mean treatment lasted 37 days (range 20-61 days). No episodes of severe bleeding/ischaemia of the extremities were observed. Treatment was discontinued once debridement was complete and granulation tissue allowed spontaneous closure/grafting. All wounds appeared stable at 1-year follow-up. CONCLUSION: The low-vacuum NPWT protocol was successful in solving five difficult cases. This regimen reduces risks associated with NPWT use on wounds with exposed vessels. The authors believe further validation is required to strengthen the evidence. However, preliminary data are encouraging and might help to change future NPWT recommendations by extending the indications for its use to exposed vessels.

Suspension of Care for Patients With Spasticity During COVID-19 Pandemic: Ethical and Medico-Legal Point of View Starting From an Italian Study.

The COVID-19 pandemic has revolutionized the habits of entire communities, having even more profound negative effects on assistance for the chronically ill. The sudden demand for extraordinary resources caught all worldwide countries unprepared, highlighting shortages in provision of care services. This applies to all patients, affected by COVID-19 or not, as many need continuing access to chronic diseases treatments. Almost all of the energy available has been directed toward care of COVID-19 patients, and almost nothing has been done to continue therapy for patients with spasticity. This study builds on a recent article and discusses its results as a basis for highlighting the ethical dilemmas and unintended consequences of health systems changing their priorities during the pandemic. The above mentioned study has shown increased patient-perceived spasticity during lockdown (72.2%) with reductions in perceived quality of life (70.9%). Telemedicine tools have proved insufficient, with access by only 7.3% of these patients. Despite the health emergency, it cannot be denied that this situation is a violation of these patients' rights and dignity. The healthcare system will also have to bear increased costs in the future to recover the loss of previous therapies benefits, because of their interruption. The real challenge will be to exploit the critical issues emerged during the pandemic, and to resolve the measures needed to take the care to the patient, and not vice versa. This applies particularly to fragile patients, to respect their dignity and right to care.
