Numerous scientists and researchers have been developing advanced procedures and methods for diagnosing the kind and phase of a human tumor. Brain tumors, which are neoplastic and abnormal developments of brain cells, are one of the most prominent causes of death. Brain tumors, also known as lesions or neoplasia, may be roughly classified as either primary or metastatic. Primary brain tumors arise from brain tissue and its surrounding environment. The recognition of brain tumors using magnetic resonance images via a deep learning technique such as convolutional neural network (CNN) has garnered significant academic interest over the last few decades. ⋯ In conclusion, we suggest that one of the next paths of study will be the incorporation of other databases to advance CNN-based brain tumor identification from magnetic resonance images. No drug dosages are applied in this work.

Phantom limb pain (PLP) is a common type of chronic pain that occurs after limb amputation. Many treatment approaches are available; however, the treatment of PLP is still a challenge. This study aimed to quantify and rank the efficacy of interventions for phantom limb pain. ⋯ Our results suggest that MT is the most optimal treatment for PLP, and a combination of therapies would enhance the therapeutic effect.

The first case of coronavirus disease 2019 (COVID-19) was reported in December 2019 in Wuhan, China. This study uses a bibliometric analysis of the top 100 most cited neurosurgical COVID-19-related articles to date to identify and determine their characteristics. ⋯ This analysis facilitated in making evidence-based clinical decisions and drawing the attention of researchers to identify and contribute to the increasing scientific work by identifying the top 100 most cited neurosurgical COVID-19-related articles published.

Dialysis disequilibrium syndrome is a rare, well-known, potentially life-threatening complication of renal replacement therapy (RRT), often involving cerebral edema and increased intracranial pressure (ICP). However, the impact of RRT on ICP and rate of dialysis disequilibrium syndrome in neurosurgical patients have not been systematically assessed. ⋯ In neurosurgical patients, ICP increases during RRT are common, affecting up to 60%, and potentially life-threatening, with mortality rates as high as 65%. The use of a continuous rather than intermittent RRT technique may reduce the risk of this complication. Prospective studies are warranted.

Macrovascular Decompression for Hemifacial spasm using Sling Technique.
Hemifacial spasm (HFS) is a painless, involuntary twitching of the facial muscles that usually involves the orbicularis oculi muscle.1,2 It is commonly caused by the anterior inferior cerebellar artery or posterior inferior cerebellar artery.1,2 However, a dolichoectatic vertebrobasilar artery (VBA) can impinge the facial nerve.1 Macrovascular decompression with sling transposition is a common management paradigm.1-9 We present a case of a 56-year-old male who presented with left-sided HFS, pulsatile tinnitus, and hearing loss for the past 2 years. The patient underwent a retrosigmoid craniotomy and Gore-Tex sling transposition of a dolichoectatic VBA (Video 1). Complete improvement of symptoms was noted postoperatively with no associated complications. We review the preoperative workup, operative technique, relevant anatomy, and literature and provide technical pearls for this procedure.
