Review Case ReportsEthical and medicolegal aspects in the management of neurosurgical emergencies among Jehovah's Witnesses: Clinical implications and review.
When an incapacitated Jehovah's Witness neurologically deteriorates and requires immediate craniectomy, institutional protocols may delay surgery if the patient's refusal of blood products is ambiguous. We are among the first to describe such an ethically contentious case in emergency neurosurgery, review the morbidity of operative delays, discuss medicolegal concerns raised, and provide a detailed guide to hemostasis in patients who refuse blood products. We discuss the case of a 46-year-old woman presented with nausea, vomiting, and right-sided weakness, progressing to stupor over several hours. ⋯ Since operative delay is a preventable cause of mortality in patients requiring urgent craniectomy, and the likelihood of requiring a transfusion from hemorrhage is minimal, an ambiguous blood consent should not postpone a potentially life-saving treatment. For the beneficence and autonomy of Jehovah's Witness patients, institutional policies should respect the family's wishes in order to expedite surgical decompression. In addition to discussing the nuances of such ethical considerations, we also provide a detailed list of commonly used, topical and parenteral hemostatic agents from the neurosurgical operating room which, depending on whether they are blood-derived, either should or should not be used when treating a Jehovah's Witness.

Case ReportsNeurological manifestations of COVID-19 and other coronavirus infections: A systematic review.
Increasing research reports neurological manifestations of COVID-19 patients. SARS-CoV-2 shares homology with other human coronaviruses that have also had nervous system involvement. ⋯ An increasing number of reports of COVID-19 patients with neurological disorders add to emergent experimental models with neuro-invasion as a reasonable concern that SARS-CoV-2 is a new neuropathogen. How it may cause acute and chronic neurologic disorders needs to be clarified in future research.

Peripheral trigeminal branch stimulation for refractory facial pain: A single-center experience.
Facial pain refractory to medical treatments may benefit from neurosurgical interventions. Only a few studies have reported on the efficacy of peripheral trigeminal stimulation and more specifically supraorbital nerve (SON) and infraorbital nerve (ION) stimulation for the treatment of facial pain. ⋯ SON and/or ION stimulation can be an effective treatment for intractable facial pain due to post-herpetic, traumatic or idiopathic etiology; however the complication rate is relatively high. Future prospective studies with longer follow-up periods are warranted.

Relationshıp of spontaneous subarachnoid haemorrhage and cerebral aneurysm to serum Visfatin and Nesfatin-1 levels.
Visfatin and nesfatin are recently discovered peptides that play a role in various metabolic reactions exhibiting inflammatory and neuroprotective effects, and their levels are known to increase in cerebral ischaemia and haematomas. Inflammation plays a role in the development of aneurysm, and spontaneous subarachnoid haemorrhage (SAH) is typically caused by rupture of the aneurysmal sac because of the increased inflammation. In the present study, we investigated the relationship between serum visfatin and nesfatin levels and the clinical and radiological findings in patients with SAH. ⋯ In the present study, we demonstrated that the presence of aneurysm, size of aneurysm, number of aneurysms correlate with visfatin and nesfatin levels in patients with SAH, and visfatin and nesfatin may be biomarkers for predicting SAH and presence of aneurysm. Nonetheless, future studies can include patients with unruptured aneurysm and investigate their serum visfatin and nesfatin levels to prove whether visfatin and nesfatin can serve as biomarkers in the follow-up of these patients.
