Chapter Hermitage of Saints Anargyroi, Kosmas and Damian: Survey, Analysis, Enhancement

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

Cervical congenital spondylolytic spondylolisthesis associated with duplication of the vertebral artery: case report.

BACKGROUND CONTEXT: Cervical bilateral congenital spondylolysis with spondylolisthesis is an abnormality both of congenital and mechanical origin, characterized by its primary feature, cervical bilateral spondylolysis. We are unaware of any reports describing cervical congenital spondylolytic spondylolisthesis associated with duplication of the vertebral artery. PURPOSE: To report the case of a patient affected with cervical bilateral congenital spondylolysis with spondylolisthesis associated with duplication of the vertebral artery. STUDY DESIGN: A unique case report from a university hospital and a literature review. PATIENT SAMPLE: An 18-year-old man who arrived at the emergency department complaining of neck pain starting from a car accident 5 days ago. METHODS: Neurologic examination and images taken by ordinary radiographs, magnetic resonance imaging (MRI) scans, ordinary computed tomography (CT) scans, and CT angiograms with three-dimensional (3D) reconstruction. RESULTS: Neurologic examination did not find evidence of strength deficit in upper extremities. Ordinary radiographs of the cervical spine showed spondylolisthesis of C6 and C7 and a cortical cleft between the superior and inferior articular facets of the C6 vertebra and spina bifida of the C6 and C2 vertebrae and an abnormal appearance of the remnant spinous processes of the cervical vertebrae. Magnetic resonance imaging confirmed the abnormalities that had been noted on the radiographs. Computed tomography scans of the cervical spine showed congenital spondylolytic spondylolisthesis and spina bifida of the C6 vertebra and duplication of the vertebral artery. They also showed double origins of the vertebral artery depicted by 3D angiographic reconstruction. Conservative treatment of wearing a cervical collar and receiving muscle relaxants and anti-inflammatory drugs was effective. With the pain completely subsided, the patient was discharged 5 days after arriving at the emergency department. CONCLUSIONS: Vascular abnormalities should be suspected and investigated in cases of congenital spondylolysis or spondylolytic spondylolisthesis. We strongly suggest performing angio-CT or angio-MRI and 3D reconstruction in these cases. Awareness of the presence of a duplicated vertebral artery and the course of its limbs could significantly help planning in cases proceeding to surgery

Holmes tremor: a delayed complication after resection of brainstem cavernomas

Objective: In this paper, the authors aimed to illustrate how Holmes tremor (HT) can occur as a delayed complication after brainstem cavernoma resection despite strict adherence to the safe entry zones (SEZs). Methods: After operating on 2 patients with brainstem cavernoma at the Great Metropolitan Hospital Niguarda in Milan and noticing a similar pathological pattern postoperatively, the authors asked 10 different neurosurgery centers around the world to identify similar cases, and a total of 20 were gathered from among 1274 cases of brainstem cavernomas. They evaluated the tremor, cavernoma location, surgical approach, and SEZ for every case. For the 2 cases at their center, they also performed electromyographic and accelerometric recordings of the tremor and evaluated the postoperative tractographic representation of the neuronal pathways involved in the tremorigenesis. After gathering data on all 1274 brainstem cavernomas, they performed a statistical analysis to determine if the location of the cavernoma is a potential predicting factor for the onset of HT. Results: From the analysis of all 20 cases with HT, it emerged that this highly debilitating tremor can occur as a delayed complication in patients whose postoperative clinical course has been excellent and in whom surgical access has strictly adhered to the SEZs. Three of the patients were subsequently effectively treated with deep brain stimulation (DBS), which resulted in complete or almost complete tremor regression. From the statistical analysis of all 1274 brainstem cavernomas, it was determined that a cavernoma location in the midbrain was significantly associated with the onset of HT (p < 0.0005). Conclusions: Despite strict adherence to SEZs, the use of intraoperative neurophysiological monitoring, and the immediate success of a resective surgery, HT, a severe neurological disorder, can occur as a delayed complication after resection of brainstem cavernomas. A cavernoma location in the midbrain is a significant predictive factor for the onset of HT. Further anatomical and neurophysiological studies will be necessary to find clues to prevent this complicatio

Management of intracranial hypertension following traumatic brain injury: A best clinical practice adoption proposal for intracranial pressure monitoring and decompressive craniectomy: Joint statements by the Traumatic Brain Injury Section of the Italian Society of Neurosurgery (SINch) and the Neuroanesthesia and Neurocritical Care Study Group of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI)

No robust evidence is provided by literature regarding the management of intracranial hypertension following severe traumatic brain injury (TBI). This is mostly due to the lack of prospective randomized controlled trials (RCTs), the presence of studies containing extreme heterogeneously collected populations and controversial considerations about chosen outcome. A scientific society should provide guidelines for care management and scientific support for those areas for which evidence-based medicine has not been identified. However, RCTs in severe TBI have failed to establish intervention effectiveness, arising the need to make greater use of tools such as Consensus Conferences between experts, which have the advantage of providing recommendations based on experience, on the analysis of updated literature data and on the direct comparison of different logistic realities. The Italian scientific societies should provide guidelines following the national laws ruling the best medical practice. However, many limitations do not allow the collection of data supporting high levels of evidence for intracranial pressure (ICP) monitoring and decompressive craniectomy (DC) in patients with severe TBI. This intersociety document proposes best practice guidelines for this subsetting of patients to be adopted on a national Italian level, along with joint statements from “TBI Section” of the Italian Society of Neurosurgery (SINch) endorsed by the Neuroanesthesia and Neurocritical Care Study Group of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI). Presented here is a recap of recommendations on management of ICP and DC supported a high level of available evidence and rate of agreement expressed by the assemblies during the more recent consensus conferences, where members of both groups have had a role of active participants and supporters. The listed recommendations have been sent to a panel of experts consisting of the 107 members of the “TBISection” of the SINch and the 111 members of the Neuroanesthesia and Neurocritical Care Study Group of the SIAARTI. The aim of the survey was to test a preliminary evaluation of the grade of predictable future adherence of the recommendations following this intersociety proposal. The following recommendations are suggested as representing best clinical practice, nevertheless, adoption of local multidisciplinary protocols regarding thresholds of ICP values, drug therapies, hemostasis management and perioperative care of decompressed patients is strongly recommended to improve treatment efficiency, to increase the quality of data collection and to provide more powerful evidence with future studies. Thus, for this future perspective a rapid overview of the role of the multimodal neuromonitoring in the optimal severe TB Imanagement is also provided in this document. It is reasonable to assume that the recommendations reported in this paper will in future be updated by new observations arising from future trials. They are not binding, and this document should be offered as a guidance for clinical practice through an intersociety agreement, taking in consideration the low level of evidence
