Abstract	Gardnerella vaginalis (G. vaginalis) is a bacterium rarely responsible for systemic infections and is exceptionally isolated from bronchopulmonary samples. Here, we report here two patients with trauma who were diagnosed with a G. vaginalis ventilatory acquired pneumonia (VAP) via mini bronchoalveolar lavage (mini-BAL). According to our observations, G. vaginalis was the only microorganism with a significant threshold and the identification was obtained by a reliable mean. There is no recommendation for antibiotic treatment for invasive G. vaginalis infection. We treated these infections with Cefotaxim and Metronidazole which clinically improved the infection. To determine whether the two patients were infected by the same strain, we used a random amplified polymorphic DNA (RAPD) technique. The two G. vaginalis organisms had distinct RAPD profiles, suggesting the absence of cross-transmission. These two cases of trauma and G. vaginalis VAP suggest that this infection cannot be ruled out and should alert the clinician to treat it.

Abstract	Tick-borne infectious diseases are increasing, driven by geographic expansion of ticks. Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne virus of the family Nairoviridae that poses serious threat to public health. CCHFV can cause severe forms of hemorrhagic fever with high case fatality rates (CFR) (10-40%) and can be transmitted from human to human. Until a few years ago, no cases of CCHF had been reported in western Europe. However, high seropositivity rates in wildlife and detection of multiple strains of CCHFV in ticks in Spain suggest that CCHFV enzootic cycle has been established in some areas of southwestern Europe. As far as CCHFV-associated morbidity and mortality are concerned, there are no approved therapeutic options or US/EU licensed vaccines for treatment. Here we discuss some eco-epidemiological aspects as well as public health and socio-economic impacts associated with CCHFV circulation and outbreaks. We also emphasize that it has become essential to identify key inter-species transmission processes of this group of pathogens, to understand basic molecular mechanisms of their replication, and to define their pathogenic potentials.

Abstract	Bilateral carotid-cavernous fistula (CCF) is a rare complication associated with severe head injury and skull base fractures. Initial presentation with hemodynamically relevant epistaxis is unusual. We report a case of a 27-year-old male presenting with severe craniocerebral injury associated with massive epistaxis. To stabilize the patient hemodynamically, the bleeding was stopped by embolization of left internal carotid artery with coils, after checking that the Willis circle is well compensated. The left CCF was embolized later with flow diverter stent when it was safe to use platelet aggregation inhibitors. Reporting this case enlighten the management of bilateral CCF with hemorrhagic shock.

Abstract	Objective: Single-pulse electrical stimulations (SPES) can elicit normal and abnormal responses that might characterize the epileptogenic zone, including spikes, high-frequency oscillations and cortico-cortical evoked potentials (CCEPs). In this study, we investigate their association with the epileptogenic zone during stereoelectroencephalography (SEEG) in 28 patients with refractory focal epilepsy. Methods: Characteristics of CCEPs (distance-corrected or -uncorrected latency, amplitude and the connectivity index) and the occurrence of spikes and ripples were assessed. Responses within the epileptogenic zone and within the non-involved zone were compared using receiver operating characteristics curves and analysis of variance (ANOVA) either in all patients, patients with well-delineated epileptogenic zone, and patients older than 15 years old. Results: We found an increase in distance-corrected CCEPs latency after stimulation within the epileptogenic zone (area under the curve = 0.71, 0.72, 0.70, ANOVA significant after false discovery rate correction). Conclusions: The increased distance-corrected CCEPs latency suggests that neuronal propagation velocity is altered within the epileptogenic network. This association might reflect effective connectivity changes at cortico-cortical or cortico-subcortico-cortical levels. Other responses were not associated with the epileptogenic zone, including the CCEPs amplitude, the connectivity index, the occurrences of induced ripples and spikes. The discrepancy with previous descriptions may be explained by different spatial brain sampling between subdural and depth electrodes. Significance: Increased distance-corrected CCEPs latency, indicating delayed effective connectivity, characterizes the epileptogenic zone. This marker could be used to help tailor surgical resection limits after SEEG.

Abstract	Objective: The purpose of this study was to identify a panel of biomarkers for distinguishing early stage sepsis patients from non-infected trauma patients. Background: Accurate differentiation between trauma-induced sterile inflammation and real infective sepsis poses a complex life-threatening medical challenge because of their common symptoms albeit diverging clinical implications, namely different therapies. The timely and accurate identification of sepsis in trauma patients is therefore vital to ensure prompt and tailored medical interventions (provision of adequate antimicrobial agents and if possible eradication of infective foci) that can ultimately lead to improved therapeutic management and patient outcome. The adequate withholding of antimicrobials in trauma patients without sepsis is also important in aspects of both patient and environmental perspective. Methods: In this proof-of-concept study, we employed advanced technologies, including Matrix-Assisted Laser Desorption/Ionization (MALDI) and multiplex antibody arrays (MAA) to identify a panel of biomarkers distinguishing actual sepsis from trauma-induced sterile inflammation. Results: By comparing patient groups (controls, infected and non-infected trauma and septic shock patients under mechanical ventilation) at different time points, we uncovered distinct protein patterns associated with early trauma-induced sterile inflammation on the one hand and sepsis on the other hand. SYT13 and IL1F10 emerged as potential early sepsis biomarkers, while reduced levels of A2M were indicative of both trauma-induced inflammation and sepsis conditions. Additionally, higher levels of TREM1 were associated at a later stage in trauma patients. Furthermore, enrichment analyses revealed differences in the inflammatory response between trauma-induced inflammation and sepsis, with proteins related to complement and coagulation cascades being elevated whereas proteins relevant to focal adhesion were diminished in sepsis. Conclusions: Our findings, therefore, suggest that a combination of biomarkers is needed for the development of novel diagnostic approaches deciphering trauma-induced sterile inflammation from actual infective sepsis.

Abstract	Introduction: Vertebrobasilar occlusion poses difficult diagnostic issues and even when properly diagnosed has a poor prognosis. Newer studies highlight a better outcome when thrombectomy was carried out between six and twenty-four hours after an initial diagnosis of stroke. This paper reports a case where a patient suffered a vertebrobasilar stroke secondary to a traumatic bilateral vertebral arteries dissection was treated with late thrombectomy. Case presentation: A 34-year-old woman was manipulated on the cervical spinal column by a chiropractor. Following three weeks of cervical pain, she presented with severe aphasia and quadriplegia (NIHSS = 28). An MRI scan indicated ischemia of the vertebrobasilar system. Thirty-one hours after the onset of these symptoms, a thrombectomy was performed. After one month, the patient could move her head and the proximal part of her limbs but remained confined to bed (NIHSS = 13). Conclusion: The current case illustrates the benefit of late mechanical thrombectomy for a posterior cerebral circulation infarct. Although there was a delay in treatment, partial recovery ensued.
