Abstract	Introduction: Delivering high-quality Neurosurgical care is dependent on excellence in neurosurgical training. Across Europe requirements of these programs vary from state to state. This study aims to determine satisfaction with these programs and views towards a unified certifications process for Neurosurgical training. Methods: An electronic survey was disseminated to European trainees, Fellows and Consultants from 11/21 to 02/22. For descriptive purposes, categorical variables, i.e. Age, Gender, year of training, country and outcomes were analyzed. Results: A total of 339 responses were submitted, representing all EANS member states except for Cyprus and Macedonia. Seventy-five were <30 years, 82.3% were male, ∼60% were Specialists, and twenty-four per cent held a fellowship with the European Board of Neurosurgery. 80.2% believed that a joint standardized Neurosurgical certificate in Europe is necessary, with 31.6% believing residency had not prepared them fully as a neurosurgeon. Conclusion: This survey shows that views towards general European-wide certification is positive and that there is ongoing consensus that there is concern with some aspects of training and high variability in its delivery across Europe.

Abstract	Background: Osteomas of the paranasal sinuses are benign, slow-growing bone tumors that can cause a variety of clinical features depending on their size and location. Most osteomas are asymptomatic and located in the frontal sinus. In rare cases, they may grow to extend into the cranial or orbital cavities, resulting in atypical presentations. The authors presented an aggressive case of a frontoethmoidal sinus osteoma with intracranial extension of an inflammatory sinonasal polyp. Observations: A 30-year-old man with a history of chronic sinusitis presented to the hospital after three episodes of loss of consciousness, chronic worsening of headache, and decreased sense of smell. Rhinoscopic examination showed mucosal polyps arising from the infundibulum and the superior meatus. Computed tomography showed a fibro-osseous mass in the left frontal sinus. Subsequent brain magnetic resonance imaging with and without contrast revealed a large, septated intracranial left frontal lesion approximately 6.5 cm in diameter that was compressing the underlying brain parenchyma. Lessons: Intracranial extension of frontal sinus osteomas can have dire neurological implications. Early detection of lesions obstructing the paranasal sinuses outlet could prevent intracranial extension of the disease. The surgical approach to such tumors may be endonasal, open cranial, or a combination of both.

Abstract	Background: Ventriculoperitoneal shunt is among the most frequent neurosurgical procedures, complicated by infection and obstruction. The first is influenced by number of skin incisions, catheter exposure and manipulation, and the latter by catheter position. Method: Presenting our neuronavigated laparoscopic-assisted minimal exposure shunt technique performed on 40 consecutive adults. No patient presented infection or distal catheter migration (mean follow-up 12 months). Ventricular catheter malpositioning associated with electromagnetic neuronavigation inaccuracy occurred in two patients with slit ventricles. Conclusion: This technique demonstrates low infection/malfunction rate, postoperative pain, and cosmetic advantages. Limiting factors are availability of laparoscopic surgeons and neuronavigation if not familiar with the approach.

Abstract	Background: Adalimumab (Humira) is a recombinant human monoclonal antibody against tumor necrosis factor alpha, which works by blocking the interaction of tumor necrosis factor alpha with its cell-surface receptors, thereby limiting the progression of inflammatory pathways. Its use is approved for several autoimmune conditions, including chronic plaque psoriasis, for which it has been prescribed as a first-line biologic treatment. Increased risks of malignancy, particularly nonmelanoma skin cancer and non-central nervous system lymphomas, have been reported with use of this drug; however, there have been no reports of central nervous system lymphomas. Case description: A 43-year-old man presented for evaluation following recent speech difficulty and a generalized tonic-clonic seizure. His medical history was significant for plaque psoriasis, for which he had been receiving treatment with adalimumab for 4 months. Magnetic resonance imaging scan of the brain with contrast agent showed a well-defined rounded enhancing lesion in the left temporal lobe with circumferential vasogenic edema. Mass effect was noted. Computed tomography scan of the chest, abdomen, and pelvis was unremarkable. He underwent excisional biopsy, and the preliminary intraoperative pathology report revealed a diagnosis of high-grade lymphoma. Subsequent analysis of morphology and immunophenotyping was consistent with primary diffuse large B-cell lymphoma of the central nervous system. Use of adalimumab was discontinued. Following combination therapy with high-dose methotrexate and rituximab along with 20 sessions of cranial radiation therapy, the patient was disease-free at 14-month follow-up. Conclusions: We report the first case to our knowledge showing a possible association of central nervous lymphoma and adalimumab.

Abstract	Background: While there is evidence that tendon adapts to training load, structural alterations in the patellar tendon in response to training loads are still unclear. The aim of this study is to identify changes in patellar tendon structure throughout pre-season and after finalizing the first competitive cycle. Methods: Nineteen professional handball players participated in the aforesaid cross-sectional study, in which patellar tendon scan and counter movement jump (CMJ) performance were conducted. Measurements were taken on the first and last day of pre-season training, and at the end of the first competitive cycle. Results: The results revealed that variation on the tendon structure occurred, mainly at the end of pre-season training; for injured tendons this occurred at the proximal (Right Conclusion: Patellar tendon shows greater structural change after completing pre-season training than at the end of the first competitive cycle, from which it may be inferred that gradual loading during pre-season training allows the tendon to adapt and potentially decrease the onset of patellar tendinopathy.

Abstract	Background: We present a rare case of multiple intracranial arteriovenous fistulas (AVFs). A young female presented with headache and a left eyelid pulsatile swelling. Case description: Magnetic resonance imaging demonstrated numerous dilated cortical veins, along with a prominent left superior ophthalmic vein. A diagnostic cerebral angiogram revealed 5 distinct AVFs including 4 dural AVFs (dAVFs) and a pial AVF (pAVF). The largest dAVF was at the superior sagittal sinus. The others included bilateral ethmoidal, torcular, and a pAVF arising of the right pericallosal artery. She was treated by endovascular transarterial Onyx embolization. Only the superior sagittal sinus fistula was treated via middle meningeal artery feeders with complete occlusion. Immediate follow-up angiogram also showed complete spontaneous occlusion of the untreated dAVFs and pial AVF. Conclusions: This case is exceedingly unique considering the multiplicity of AVFs, concurrent presence of pial and dural AVF, and spontaneous occlusion of all untreated AVFs after embolizing the largest shunting fistula.

Abstract	Hyaline cartilage's inability to self-repair can lead to osteoarthritis and joint replacement. Various treatments, including cell therapy, have been developed for cartilage damage. Autologous chondrocyte implantation (ACI) is considered the best option for focal chondral lesions. In this article, we aimed to create a narrative review that highlights the evolution and enhancement of our chondrocyte implantation technique: High-Density-ACI (HD-ACI) Membrane-assisted Autologous Chondrocyte Implantation (MACI) improved ACI using a collagen membrane as a carrier. However, low cell density in MACI resulted in softer regenerated tissue. HD-ACI was developed to improve MACI, implanting 5 million chondrocytes per cm

Abstract	Background: Intrasaccular flow disruption has emerged as a useful modality for treatment of wide-necked saccular aneurysm at vessel bifurcations. The Woven EndoBridge (WEB) device is one such device that has been evaluated in several series with excellent safety and good midterm efficacy. Bailout techniques to retrieve or reposition a dislocated WEB device are sparse and associated with significant risks. We describe a case of a dislocated WEB device that was repositioned with a microcatheter alone. Methods: We describe a case of a WEB device that inadvertently detached in the parent vessel and the technique we used to reposition it. A number of bailout techniques are discussed with pros and cons associated with each maneuver. Results: An unruptured middle cerebral artery (MCA) aneurysm was treated by endovascular embolization with a WEB device. The WEB was deployed within the aneurysm without incident. However, the device failed to detach. While attempting to resheath the device, it extruded out of the aneurysm and then inadvertently detached in the MCA. After many options were considered, a microcatheter alone was used to push the device back into the aneurysm. Conclusion: Caution should be exercised, especially when detaching the WEB device. Microcatheter repositioning by pushing the dislocated device may be attempted, especially if part of the device is within the aneurysm. This is the first description of the described microcatheter repositioning rescue maneuver.
