Cervical Spinal Cord Stimulation for Trigeminal Neuralgia: a Narrative Review.

Curr Pain Headache Rep 2022 Jun 18. Epub 2022 Jun 18.

Peconic Bay Medical Center/Northwell Health, Riverhead, NY, USA.

Background: Trigeminal neuralgia (TN) is a chronic neuropathic pain condition affecting one or more divisions of the fifth cranial (trigeminal) nerve. TN is defined by recurrent unilateral electric shock-like pain that is abrupt in both onset and termination. The pain is triggered by innocuous sensory stimuli and is classified as either classic TN, related to vascular compression; secondary TN, due to a tumor along the trigeminal nerve or an underlying disease like multiple sclerosis; or idiopathic TN.

Successful treatment of vancomycin-resistant enterococcal infection of an external ventricular drain with 2 weeks of intravenous linezolid.

Access Microbiol 2022 29;4(3):000335. Epub 2022 Mar 29.

Department of Medical Microbiology, Queen Elizabeth University Hospital, 1345 Govan Road, Glasgow G51 4TF, UK.

Hydrocephalus is a common condition worldwide, and is frequently managed by diversion of cerebrospinal fluid (CSF), either externally with a drain or internally with a shunt. An external ventricular drain (EVD) can be an essential treatment modality, but is associated with a risk of infection, most commonly caused by species, which can result in meningitis or ventriculitis and a delay in the definitive management of the hydrocephalus. Here, we report the case of a patient who required an EVD to manage post-operative hydrocephalus following a craniotomy and microvascular decompression for trigeminal neuralgia. Read More

Department of Stomatognathic Function and Occlusal Reconstruction, Graduate School of Biomedical Sciences, Tokushima University, Tokushima 770-8504, Japan.

Trigeminal neuralgia is unilateral, lancinating, episodic pain that can be provoked by routine activities. Anticonvulsants, such as carbamazepine, are the drugs of choice; however, these possess side-effects. Microvascular decompression is the most effective surgical technique with a higher success rate, although occasionally causes adverse effects. Read More

Deep Learning Based Real-Time Semantic Segmentation of Cerebral Vessels and Cranial Nerves in Microvascular Decompression Scenes.

Cells 2022 06 2;11(11). Epub 2022 Jun 2.

Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China.

Automatic extraction of cerebral vessels and cranial nerves has important clinical value in the treatment of trigeminal neuralgia (TGN) and hemifacial spasm (HFS). However, because of the great similarity between different cerebral vessels and between different cranial nerves, it is challenging to segment cerebral vessels and cranial nerves in real time on the basis of true-color microvascular decompression (MVD) images. In this paper, we propose a lightweight, fast semantic segmentation Microvascular Decompression Network (MVDNet) for MVD scenarios which achieves a good trade-off between segmentation accuracy and speed.

Neuralgia and Atypical Facial, Ear, and Head Pain.

Otolaryngol Clin North Am 2022 Jun;55(3):595-606

Caruso Department of Otolaryngology Head & Neck Surgery, University of Southern California, 1537 Norfolk Street, Suite 5800, Los Angeles, CA 90033, USA. Electronic address:

Though there have been considerable strides in the diagnosis and care of orofacial pain disorders, facial neuralgias, and myofascial pain dysfunction syndrome remain incredibly cumbersome for patients and difficult to manage for providers. Cranial neuralgias, myofascial pain syndromes, temporomandibular dysfunction (TMD), dental pain, tumors, neurovascular pain, and psychiatric diseases can all present with similar symptoms. As a result, a patient's quest for the treatment of their orofacial pain often begins on the wrong foot, with a misdiagnosis or unnecessary procedure, which makes it all the more frustrating for them.

J Korean Neurosurg Soc 2022 Jun 9. Epub 2022 Jun 9.

Brain Research Institute, Department of Neurosurgery, Yonsei University College of Medicine, Seoul, Korea.

Microvascular decompression is the gold standard for the treatment of trigeminal neuralgia (TN). However, percutaneous techniques still play a role in treating patients with TN and offer several important advantages and efficiency in obtaining immediate pain relief, which is also durable in a less invasive and safe manner. Patients' preference for a less invasive method can influence the procedure they will undergo. Read More

Department of Neurology, Queen Elizabeth Hospital, Kota Kinabalu, Malaysia.

As the world embarks on mass vaccination against SARS-CoV2 to alleviate the spread of this highly contagious novel coronavirus, there are growing anecdotal reports on immune-related neurological complications following immunisation. Similarly, we encountered 2 cases of central nervous system demyelination at our centre with Comirnaty (BNT162b2), a mRNA-based COVID-19 vaccine. Our first patient had typical clinical-radiological manifestations of acute disseminated encephalomyelitis (ADEM) after his COVID-19 vaccination. Read More
