BACKGROUND: Patients who have undergone intracranial neurosurgical procedures have traditionally been admitted to an intensive care unit (ICU) for close postoperative neurological observation. The purpose of this study was to systematically review the evidence for routine ICU admission in patients undergoing intracranial neurosurgical procedures and to evaluate the safety of alternative postoperative pathways. METHODS: We were interested in identifying studies that examined selected patients who presented for elective, non-emergent intracranial surgery whose postoperative outcomes were compared as a function of ICU versus non-ICU admission...

Neoplastic leptomeningeal disease (LMD) represents infiltration of the leptomeninges by tumor cells. Knowledge of the frequencies of locations of LMD on MRI may assist in early detection, help elucidate the process of leptomeningeal spread of cancer and understand how LMD affects the central nervous system. Our goal was to identify intracranial sites of neoplastic LMD predilection on MRI in patients with cytologically-proven LMD. The presence of FLAIR signal hyperintensity and T1-weighted post-contrast enhancement in the sulci of the supratentorial compartment and cerebellum and enhancement of the cranial nerves (CNs), basal cisterns, pituitary stalk, and ependymal surface of the lateral ventricles, as well as the presence of parenchymal metastasis were recorded...

'Painful tic convulsif' (PTC) describes the coexistence of hemifacial spasm and trigeminal neuralgia. In this report, we describe a unique presentation of bilateral PTC in a man with bilateral hemifacial spasm and trigeminal neuralgia secondary to neurovascular conflict of all four cranial nerves. Following failed medical and radiofrequency therapy, microvascular decompression of three of the four involved nerves was performed, where the offending vessels were mobilised and Teflon used to prevent conflict recurrence...

OBJECTIVES: To measure the urodynamic effects of electrical co-stimulation of two individual sites in the proximal and distal urethra in persons with spinal cord injury (SCI). This work was motivated by preclinical findings that selective co-stimulation of the cranial urethral sensory nerve and the dorsal genital nerve, which innervate the proximal and distal portions of the urethra, respectively, increased reflex bladder activation and voiding efficiency. METHODS: Electrical co-stimulation of urethral afferents was conducted in persons with chronic SCI during urodynamics...

OBJECTIVE Microvascular decompression (MVD) is effective for the treatment of trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia. The transposition technique is the standard procedure to avoid adhesions and granuloma around the decompression site but is more complex and difficult to perform than the interposition technique. The authors describe a simple and safe MVD transposition procedure they call the "birdlime" technique, which uses a tissue glue-coated collagen sponge soaked with fibrin glue, and the results of this technique...

REVIEW
Rajeev Nayak
Acute neuromuscular paralysis (ANMP) is a clinical syndrome characterized by rapid onset muscle weakness progressing to maximum severity within several days to weeks (less than 4 wk). Bulbar and respiratory muscle weakness may or may not be present. It is a common neurological emergency which requires immediate and careful investigations to determine the etiology because accurate diagnosis has significant impact on therapy and prognosis. Respiratory failure caused by neuromuscular weakness is considered as more critical than lung disease because its development may be insidious or subtle until sudden decompensation leads to life threatening hypoxia...

Fabry disease (FD) is an X-linked lysosomal storage disease, with multisystemic glycosphingolipids deposits. Neuro-otological involvement leading to hearing loss and vestibular dysfunctions has been described, but there is limited information about the frequency, site of lesion, or the relationship with peripheral neuropathy. The aim was to evaluate the presence of auditory and vestibular symptoms, and assess neurophysiological involvement of the VIII cranial nerve, correlating these findings with clinical and neurophysiological features of peripheral neuropathy...

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization)...

Lewis-Sumner syndrome (LSS) is a rare disease characterized by asymmetrical and multifocal mononeuropathy commonly located in the upper limbs. Some rare cases affecting cranial nerve have been described, but LSS is unknown to affect especially laryngeal nerves. This paper presents the first case of unilateral vocal fold paresis caused by an LSS in a 59-year-old man complaining of dysphonia, breathy voice, and vocal fatigue. Epidemiology, clinical features, diagnosis, and treatment will be described.

BACKGROUND: The first description of the voluntary motor function of the facial nerve and separate sensory-motor contributions of the trigeminal nerve is most commonly attributed to Charles Bell. However, a review of the original scientific accounts and subsequent historical publications question the validity of this credit. The objective of the present historical analysis is to clarify the contributions of Herbert Mayo toward discovering the functions of the fifth and seventh cranial nerves and to raise awareness of this historical controversy within the medical literature...

Emily J Lessner, Michelle R Stocker
The examination of endocranial data of archosauriforms has led to advances on the evolution of body size, nerve pathways, and sensory abilities. However, much of that research has focused on bird-line archosaurs, resulting in a skewed view of Archosauria. Phytosauria, a hypothesized sister taxon to or early-branching member of Archosauria, provides a potential outgroup condition. Most previous phytosaur endocranial studies were executed without the use of modern technology and focused on derived members of Phytosauria...

Acute oculomotor nerve palsy requires urgent exclusion of aneurysmal compression. We report a 62year old man with a transient right third nerve palsy with pupillary involvement, who was found to have neurovascular compression of the cisternal oculomotor nerve as it curved over a duplicated superior cerebellar artery on high resolution MR imaging. Direct vascular compression should be considered in patients with isolated cranial neuropathies in whom other pathologies have been excluded.

Purpose: Speech-language pathologists (SLPs) who work with adults with dysarthria were surveyed to investigate trends of clinical practice for assessing speech intelligibility. Method: Two hundred ninety-six SLPs responded to an online survey October 22-November 30, 2015. Results: Findings showed that 35% of SLPs lacked access to any standardized assessments of intelligibility, with 66% of these implicating cost as the main reason. Work settings played a role, as all SLPs working in Veterans Affairs hospitals and 97% of SLPs working in university or research clinics reported access to at least one formal assessment...
