OBJECTIVE: To compare the clinical outcomes of ex vivo liver resection and autotransplantation (ERAT) with allotransplantation in end-stage hepatic alveolar echinococcosis (HAE) patients. METHODS: From January 2008 to October 2017, 41 of 254 patients with end-stage HAE fulfilled the inclusion criteria (group ERAT, n=35 versus group allotransplantation, n=6). Each group was assessed for indications and short- and long-term outcomes. RESULTS: The intraoperative mortality was zero in both groups...

Intracerebral haemorrhage (ICH) is a devastating condition with limited treatment options, and current understanding of pathophysiology is incomplete. Spontaneous cerebral bleeding is a characteristic of the human condition that has proven difficult to recapitulate in existing pre-clinical rodent models. Zebrafish larvae are frequently used as vertebrate disease models and are associated with several advantages, including high fecundity, optical translucency and non-protected status prior to 5 days post-fertilisation...

The Pathology Museum of the University of Florence houses a rich collection of anatomical specimens and over a hundred waxworks portraying pathological conditions occurring in the nineteenth century, when the museum was established. Clinical and autopsy findings of these cases can still be retrieved from the original museum catalogue, offering a rare opportunity for retrospective palaeo-pathological diagnostics. We present a historical case of severe hydrocephalus backed by modern-day anthropological, radiological and molecular analyses conducted on the skeleton of an 18-month-old male infant deceased in 1831...

Tissue plasminogen activator (t-PA) remains to be the only FDA-approved drug for ischaemic stroke, but it has a restrictive therapeutic window with 4.5 hours. Beyond the golden time window, thrombolytic treatment carries the risk of haemorrhagic transformation (HT). The blood-brain barrier (BBB) disruption is a critical step in the t-PA-mediated HT. Although large efforts are made to explore the mechanisms of the BBB disruption and HT, the underlying mechanisms are largely unknown. Thrombolytic treatment for recanalization could produce reactive oxygen species (ROS) and reactive nitrogen species (RNS) and mediate cerebral ischaemia-reperfusion injury...

Fetal stroke is an important cause of cerebral palsy but is difficult to diagnose unless imaging is undertaken in pregnancies at risk because of known maternal or fetal disorders. Fetal ultrasound or magnetic resonance imaging may show haemorrhage or ischaemic lesions including multicystic encephalomalacia and focal porencephaly. Serial imaging has shown the development of malformations including schizencephaly and polymicrogyra after ischaemic and haemorrhagic stroke. Recognised causes of haemorrhagic fetal stroke include alloimmune and autoimmune thrombocytopaenia, maternal and fetal clotting disorders and trauma but these are relatively rare...

BACKGROUND: Mechanical thrombectomy (MT) in association with intravenous thrombolysis is recommended for treatment of acute ischemic stroke (AIS), with large vessel occlusion (LVO) in the anterior circulation. Because MT is only available in comprehensive stroke centers (CSC), the challenge of stroke organization is to ensure equitable access to the fastest endovascular suite. Our aim was to evaluate the feasibility, efficacy, and safety of MT in patients initially managed in 1 CSC (mothership), compared with patients first managed in primary stroke center (PSC), and then transferred to the CSC for MT (drip-and-ship)...

BACKGROUND: Xingnaojing injection (XNJ) sharpen the mind and induce consciousness and are widely used in acute phases of intracerebral hemorrhage (ICH). Naloxone hydrochloride injection (NX) performs equally well and replace the effects of morphine-like substances to promote conscious awareness. The applications of XNJ combined with NX for ICH show some advantages compared with NX applied individually. The aim of this systematic review is to evaluate the effectiveness and safety of XNJ combined with NX for ICH...

OBJECTIVE: To test the hypothesis that impaired cerebral autoregulation (ICA) increases the susceptibility of premature infants to adverse outcomes, we determined the relationship of ICA and cerebral reactivity (CR) measured in the first 96 hours of life to the outcome of grade 3 or 4 intraventricular haemorrhage (IVH) and/or death within 1 month. SETTING: Single-centre level IV neonatal intensive care unit. PATIENTS: Neonates 24-29 weeks' gestation less than 12 hours old with invasive blood pressure monitoring...

BACKGROUND/AIM: Endovascular thrombectomy may be performed in anticoagulated patients taking vitamin-K antagonists (VKA) or direct-acting oral anticoagulants (DOAC) in whom the use of intravenous tissue plasminogen activator (tPA) is contraindicated. We aimed to investigate the efficacy and safety of mechanical thrombectomy specifically in anticoagulated patients ineligible for thrombolysis. METHODS: We performed a retrospective analysis of a prospectively collected database of consecutive ischaemic stroke patients undergoing mechanical thrombectomy from January 2008 to June 2017...

Neonatal seizures are the most common neurological event in newborns, showing higher prevalence in preterm than in full-term infants. In the majority of cases they represent acute symptomatic phenomena, the main etiologies being intraventricular haemorrhage, hypoxic-ischemic encephalopathy, central nervous system infections and transient metabolic derangements.Current definition of neonatal seizures requires detection of paroxysmal EEG-changes, and in preterm newborns the incidence of electrographic-only seizures seems to be particularly high, further stressing the crucial role of electroencephalogram monitoring in this population...

Uric acid (UA) therapy may prevent early ischemic worsening after acute stroke in thrombolysis patients. The aim of this study was to examine the influence of UA on the thrombolytic efficacy of alteplase in human blood samples by measuring thrombolysis under flow conditions using a newly developed microchip-based flow-chamber assay. Human blood samples from healthy volunteers were exposed to UA, alteplase, or a combination of UA and alteplase. Whole blood and platelet-rich plasma were perfused over a collagen- and thromboplastin-coated microchip, and capillary occlusion was monitored with a video microscope and flow-pressure sensor...

BACKGROUND: Many researchers have found correlation between tortuous arteries and development of aneurysms in cerebral arteries. However, due to our knowledge, there are no studies analysing impact of tortuosity on risk of subarachnoid haemorrhage occurrence. Therefore, we decided to determine, whether tortuosity of Anterior Cerebral Artery can be related to rupture of Anterior Communicating Artery aneurysm, as well as to severity and treatment outcome of subarachnoid haemorrhage. METHODS: We retrospectively analyzed the Anterior Cerebral Artery anatomy of 121 patients with Anterior Communicating Artery aneurysms...

BACKGROUND: Most ischaemic strokes are caused by blockage of a cerebral artery by a thrombus. Intravenous administration of recombinant tissue plasminogen activator given within 4.5 hours is now standard treatment for this condition. Percutaneous vascular interventions use an intra-arterial, mechanical approach for thrombus disruption or removal (thrombectomy). Recent randomised trials indicate that percutaneous vascular interventions are superior to usual care (usual care usually included intravenous thrombolysis)...

Ischaemic stroke can occur when an artery to the brain is blocked by a blood clot. The use of thrombolytic agents, such as tissue plasminogen activator (tPA), to dissolve the occluding clot is limited by the risk of intracerebral haemorrhage (ICH), a known side effect associated with tPA. We developed a computational thrombolysis model for a 3D patient-specific artery coupled with a compartmental model for temporal concentrations of tPA and lysis proteins during intravenous infusion of tPA, in order to evaluate the effects of tPA dose on the efficacy of thrombolytic therapy and the risk of ICH...

The aim was to review the neurointensive care (NIC) of cerebral venous sinus thrombosis patients with haemorrhage during a 15-year period. This is a severe condition with substantial mortality caused by increased intracranial pressure (ICP) and studies are lacking describing the complex picture of the NIC, which offers a large treatment arsenal for intracranial hypertension. Patients treated 2000-2015 were investigated. Data regarding patient characteristics, symptoms, imaging, ICP-treatment, NIC-treatment intensity, and outcome were collected and analysed...
