Total craniopagus is an exceedingly rare condition in which surgical treatment is complex and potentially fatal. Over the last decades, a multistep surgical approach, which allows development of venous collateral circulation, has fostered a dramatic improvement of successful separation rates and neurological outcomes. Most of the experience derives from management of vertical craniopagus, the angular form being rarer and less amenable to successful surgical separation.

We present a case of total angular craniopagus twins observed at our Institution. Specific features included a large occipital fusion area with a bone defect, complete separation of brain and arterial vessels and a complex configuration of dural venous sinuses. The superior sagittal sinus of each twin preferentially drained to a single transverse sinus through a shared torcular.

After an extensive diagnostic phase, including neuroimaging, tridimensional and virtual reality modelling, neurological, neurophysiological and rehabilitation assessment, a detailed multistep surgical plan, was proposed to a wide multidisciplinary team. The venous system was managed by taking advantage of the fact each twin's superior sagittal sinus was drained preferentially by the transverse sinus on the twin's left. The transverse sinuses were thus separated accordingly.

Successful separation was achieved in three surgical steps over one year, with an excellent outcome for both twins.

to evaluate the effects of acellular nerve grafts (ANGs) with bone marrow mesenchymal stem cells (BMSCs) or Schwann cells (SCs) on the treatment of sciatic nerve defect in rats.

Electronic databases were accessed to identify eligible targets. ANGs data were extracted for meta-analysis using Review Manager 5.3.

The rats subjected to ANGs+BMSCs or ANGs+SCs are characterized by different sciatic nerve function index, nerve conduction, latency, amplitude, myelin sheath thickness, myelinated nerve fibers and gastrocnemius wet weight. Accompanied with evidently superior recovery of limb function. These differences are of statistical significance (P < 0.05) when compared to that of control group with ANGs only.

ANGs with BMSCs or SCs can promote nerve regeneration and functional recovery in peripheral nerve defects.

Intravenous thrombolysis and endovascular reperfusion represent nowadays the standard treatment for acute ischemic stroke. However, ineffective reperfusion may occur, representing a major negative prognostic factor on clinical outcome. Extracranial-intracranial (EC-IC) bypass revascularization procedure in an acute setting appears as a promising tool in order to increase reperfusion rates and improve clinical outcome in a highly selected population refractory or ineligible for standard reperfusion therapies.

The Extracranial-Intracranial Revascularization for Acute Stroke - Parma (EIRASP) study is an observational, prospective, single-centre, study (protocol 203/2020/OSS/AOUPR). Patients admitted for an acute ischemic anterior circulation stroke due to large vessels occlusion and refractory or ineligible for standard reperfusion therapies will be submitted to an extracranialintracranial bypass revascularization procedure when fulfilling all clinical and radiological inclusion criteria. The primary outcome will be the functional outcome (modified Rankin Scale and NIHSS score) at 3 months after the surgical procedure. Secondary outcome will include the evaluation of clinical and surgical complications rates, quantitative monitoring of perfusion parameters, and further functional and survival rates.

Despite promising data regarding the feasibility and the favourable outcome of urgent EC-IC bypass revascularization procedure in selected patients suffering an acute ischemic stroke are emerging in literature, no studies to date have prospectively explored the real potential of this technique.

The EIRASP study aims to provide further and stronger methodological evidence of the benefit of urgent EC-IC bypass revascularization procedure in acute ischemic stroke.

The diagnosis, classification and treatment of thoracolumbar burst fractures, continue to be controversial. Surgery is generally the preferred treatment for unstable fractures while stable fractures are managed conservatively. This study aims to describe surgical procedures, outcomes, complications, demography, clinical features and differences between A3 and A4 fractures (AO classification) of the thoracolumbar region. A subgroup of patients <91 years with osteoporotic fractures is included and analyzed.

Analysis of data from the german spine registry "DWG-Register" on operative treatment for thoracolumbar AO A3 and A4 fractures out of 170 departments from January 2017 to May 2021. The evaluated variables included age, gender, surgical approach (posterior, anterioror combined), and re-operation.

In total, 4230 AO A3 and A4 thoracolumbar fractures were identified in the registry; n=2898 A3 (group 1) and n= 1332 A4 (group 2). The preoperative ASIA-impairment scale score in group 1 was significantly diroaches are more often used in A4 type fractures, probably because of its inherent instability related to burst fractures, surprisingly, not associated with the occurrence of added perioperative complications. Nevertheless, A3 type fractures are presented with worse ASIA Impairment-Scale at admission, in comparison with A4 type fractures of the thoracolumbar region.
Selumetinib is a MEK inhibitor, which is effective with an acceptable safety profile in reducing the volume of symptomatic inoperable plexiform neurofibromas in some clinical trials and also has been recently approved by FDA for use in children aged 2 years or older. However, no systematic review has yet been performed to provide a collective estimate of the results of all these trials.

Articles describing the use of selumetinib in patients with neurofibromatosis type-1 (NF1) with inoperable plexiform neurofibromas were searched from different electronic databases. The objectives were to provide a pooled estimate of efficacy evaluated by direct measurement and also by various functional measures, as well as the proportion of patients with adverse events. For determining pooled estimates, we included only studies with a minimum sample size of 15 with a prospective study design.

A total of eight articles with 137 patients were found and 134 patients in six uncontrolled trials were included in the quantita%), paronychia (6%), and acneiform rash (17%). A total of 17% patients required dose reduction due to these toxic effects and 10.5% (95% CI-4.0%, 17.0%) of patients discontinued due to toxic effects.

Selumetinib can produce sustained shrinkage in the majority of patients with NF1 and symptomatic plexiform neurofibroma to provide clinically meaningful benefit in functional ability, with more robust evidence in children. The acceptable safety profile and absence of cumulative toxic effects permit long-term treatment with selumetinib.

The recent emphasis on simulation-based training in neurosurgery has led to the development of many simulation models and training courses. We aim to identify the currently available simulators and training courses for neurovascular surgery and endovascular interventions to assess their validity and determine their effectiveness to suggest widespread applicability in educational curricula.

Literature research was performed on academic databases for English language articles that validate simulation or virtual reality intracranial aneurysm models. Studies for neurosurgery and interventional neuroradiology published between January 2011 and January 2021 were included. Each study was assessed according to the Medical Education Research Quality Instrument.

Between January 2011 and January 2021, 44 articles were screened and 12 were identified to be included in our research. The study involved 177 trainers. Participant trainers' characteristics reveal sensible homogeneity between studies. All studies reported a significant improvement in technical outcomes after simulator or virtual reality training. The Medical Education Research Quality Instrument average rate from 12 studies was M=11,7 (range 8,5-14,5).

Nowadays, the training of a medical doctor in the neurovascular field benefits from modern methods like simulators and virtual reality. With the advent of increasing neurosurgery simulators and training instruments, there is a need for more validity studies. More training tools incorporating full-immersion simulation are recommended to develop a standardized learning curve in neurovascular procedures.

Chronic low back pain (LBP) can be caused by sacroiliac joint (SIJ) disease. Many conditions could cause SIJ dysfunction. The lateral branches of the L4-S3 dorsal rami are responsible for the primary innervation of the posterior SI joint. Radiofrequency (RF) denervation represent an emerging promising treatment for refractory sacroiliac joint pain. There are different types of RF denervation such as thermal or cooled. Use of irrigation cooled electrodes allows targeted tissues to reach the neuroablative temperatures slowly, preventing collateral damage of adjacent tissue.

We conducted electronic database (Pubmed, Medline, Cochrane and Google Scholar) research (time frame January 1st, 2010 to May 31st, 2021) for clinical studies that had tested RFT (Conventional Radiofrequency) and RFC (Cooled Radiofrequency) to treat sacroiliac joint pain. These studies were evaluated according to Level of Evidence. this website Quantitative assessment of qualifying studies was done using the random effects model. We calculated the poe this deficient aspect.
Current evidence indicates no statistical difference between two techniques examined. The literature is currently lacking, and well-constructed randomized clinical trials are necessary to evaluate this deficient aspect.
Essential tremor (ET) may severely impact patient's quality of life. Several techniques such as radiofrequency, Deep Brain Stimulation (DBS), Gamma Knife (GK) radiosurgery and high-intensity focused ultrasound may be used for the surgical treatment of ET. The aim of this paper is to summarize the most recent available literature on DBS, transcranial Magnetic Resonance-guided Focused Ultrasound (tcMRgFUS) and GK, and to compare indications, targets, and effectiveness of these surgical techniques for the treatment of ET.

A systematic review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The literature search was performed on the three largest medical databases (PubMed, Scopus and Web of Science). This systematic review is focused on the effectiveness and safety of GK, DBS, and tcMRgFUS as functional neurosurgical techniques for the treatment of ET. We aim to compare these techniques by evaluating mode, target, effectiveness in improving motor outcomes, and rates of adverse effects.
