Effects of immediate thrombolytic treatment in imaging area on functional outcome in patients with acute ischemic stroke.

INTRODUCTION: Door-to-needle time (DNT) is an established predictor of outcome in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT). Several strategies have been proposed to streamline in-hospital pathways, among which treatment at CT/MR bed. AIM: To explore the impact of treatment at CT/MR bed, here defined as imaging area (IA), on functional outcome in stroke patients treated with IVT alone. METHODS: All AIS patients treated with IVT alone at our center in 2020, 2021, and 2022 were included. Patients with any previous disability were excluded. The cohort was divided into two groups, depending on the treatment site. One group received IVT at IA, the other at emergency room or stroke unit (non-IA). Regression analysis assessed the association between treatment site and 3-month outcome. RESULTS: A total of 327 patients who received IVT alone were included in the analysis. One hundred thirty-three (40.7%) were in the IA group and 194 (59.3%) in the non-IA group. The groups showed similar baseline characteristics. In the IA group, DNT was 45 min shorter. Despite similar rates of functional independence (mRS 0-2), the IA group showed higher rates of excellent outcome (mRS 0-1) compared to the non-IA group (60.1% vs 42.8%, p<0.01). Immediate treatment at IA was independently associated to excellent outcome (OR 1.78 [1.03-3.08]). CONCLUSIONS: Thrombolytic treatment at IA lowers DNT and is an independent predictor of excellent outcome after AIS. Our study emphasizes the importance of immediate thrombolytic treatment at IA, soon after radiological eligibility is confirmed. Immediate treatment at IA should be a standard-of-care for AIS.

Overview of presurgical assessment and surgical treatment of epilepsy from the Italian League Against Epilepsy.

The Commission for Epilepsy Surgery of the Italian League Against Epilepsy (LICE) presents an overview of the techniques and methodologies of presurgical evaluation and of the surgical treatment of epilepsies. This overview is the result of the experience developed in the past years in the major Italian centers where programs of epilepsy surgery have been established, and it has the aim of offering a quick and easy reference tool for those involved in the treatment of patients with epilepsy. The sharing of different experiences has the additional aim of conforming and disseminating the employed techniques as well as the methods of selection and evaluation of patients. The synthetic coverage of the main issues concerning the presurgical workup and the available surgical options will hopefully provide a framework that may integrate and develop the contributions of every single center, in one of the more complex, challenging, and dynamic areas of neurological sciences.

Long term results of Dorsal Root Entry Zone (DREZ) lesions for the treatment of intractable pain: A systematic review of the literature on 1242 cases.

BACKGROUND: Different Dorsal root entry zone (DREZ) lesion techniques have been reported as effective treatment for intractable painful conditions, though with contradictory results. Overall, good results were reported especially in specific conditions, such as pain due to brachial plexus avulsion, spinal cord injuries and oncological pain management. However, data on long term results in different clinical conditions are still missing. OBJECTIVE: This study aims to systematically review the pertinent literature to evaluate indications, clinical outcomes, and complications of DREZ lesion (DREZotomy), in chronic pain management. METHODS: A systematic literature review was conducted according to the PRISMA statement. Papers on DREZotomy for chronic pain in cancer, brachial plexus avulsion, spinal cord injury, post herpetic neuralgia, and phantom limb pain were considered for eligibility. For each category we further identified two sub-group according to the length of follow up: medium term and long term follow up (more than 3 years) respectively. RESULTS: 46 papers, and 1242 patients, were included in the present investigation. When considering long term results DREZotomy provided favorable clinical outcomes in brachial plexus avulsion and spinal cord injury, in 60.8% and 55.8% of the cases respectively. Conversely, the success rate was 35.3% in phantom limb pain and 28.2% in post herpetic neuralgia. A poor clinical outcome was reported in over than 25% of the patients suffering from phantom limb pain, post herpetic neuralgia and spinal cord injury. The mean complications rate was 23.58%. While BPA and SCI patients presented stable improvement over time, good outcomes among PHN and PLP groups dropped by - 46.2%; and - 14.7% at long term follow up respectively. CONCLUSION: DREZotomy seems to be an effective treatment for chronic pain conditions, especially for brachial plexus avulsion, spinal cord injury and intractable cancer/post-radiation pain. According to the low level of evidence of the pertinent literature, further studies are strongly recommended, to better define potential benefits and limitations of this technique.
