BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

BACKGROUND: Frey syndrome is one of the important complications of parotid surgery. Placing a barrier between the parotid gland and the skin flap is considered to be effective for preventing this syndrome by blocking misdirected regeneration of nerve fibers. Neoveil is nonwoven polyglycolic acid (PGA) felt that is used as absorbable reinforcing material. The present study evaluated the effectiveness of this PGA felt as a barrier for preventing Frey syndrome. METHODS: A total of 19 patients who underwent superficial parotidectomy from 2012 to 2017 were retrospectively reviewed...

INTRODUCTION Sensory innervation of the dorsomedial surface of the hand usually depends on the dorsal ulnar nerve (DUN). Innervation in this area by the superficial radial nerve (SRN) has been described as a normal variant. METHODS We studied 358 patients using nerve conduction of the DUN and SRN with dorsomedial recording. Each hand was classified into usual innervation (only DUN response), mixed variant (response of both nerves) or complete variant (only SRN response). RESULTS Mixed innervation was found in 14...

Biopsy of the superficial temporal artery is often used in the diagnosis of giant cell arteritis, but at traditional sites there is a risk of injury to the facial nerve. Recently the Gillies incision has been suggested as an alternative means of access for the biopsy, but the anatomical basis of this has not been fully elucidated. We therefore undertook a radiographic review of 150 patients, and examining 300 vessels, to find out. Our results indicated that there is considerable variability in the position of the bifurcation of the superficial temporal artery, and so a Gillies approach may not be reliable, particularly if access to the bifurcation is required...

Background: Infratentorial siderosis (iSS) is a progressive degenerative disorder targeting primarily the cerebellum and cranial nerve eighth; therefore, progressive ataxia and its neuro-otological findings are common. Toxicity from hemosiderin involves selectively vulnerable neurons and glia in these posterior fossa structures. Other neurologic findings may be present, though our focus relates to the cochlea-vestibular cerebellar involvement. Radiographic evidence of siderosis may be the result of recurrent, albeit covert bleeding in the subarachnoid space, or the consequence of an overt post-traumatic or aneurysmal subarachnoid hemorrhage (SAH)...

The "superficial fascia" is often interpreted as "tendon-membrane like structure" in acupuncture field and it is speculated that acupuncture stimulation-induced structural alteration of the superficial fascia may contribute to the alleviation of many medical conditions. The fact is that the superficial fascia mainly consists of subcutaneous adipose tissue and fibrotic network (which function in storing, supporting and buffering external pressure and are not responsible for producing " Deqi " or "needling sensations"), and has no typical tendon or membrane structure in hypodermis...

OBJECTIVE: The application of laser interstitial thermal therapy (LITT) for intracranial lesions in the posterior fossa tumors remains challenging due to the smaller size of this compartment as well as the thickness and angle of the occipital bone. The objective of this study was to review our experience with this treatment modality for posterior fossa lesions. METHODS: We retrospectively reviewed our series of eight patients with posterior fossa tumors treated with LITT from an IRB approved brain tumor database (2012 to 2017) of over 200 LITT cases in our institution...

Background: Neurofibromatosis is a genetically inherited disorder of the nervous system (brain and spinal cord) which mainly affects the development of nerve (neural) cell tissues, causing tumors (neurofibromas) to develop on nerves. It is the most common single gene disorder of the nervous system and inheritance is through autosomal dominance. They are usually classified into types 1 and 2, the type 1 is the commoner type and also known as superficial neurofibroma. Plexiform neurofibromas are the next most common type of tumor in individuals with type 1 neurofibroma...

The superficial branch of the radial nerve (SBRN) at the wrist is susceptible to trauma and lacerations. These lesions can develop into painful neuromas with debilitating consequences. The aim of our study was to demonstrate the effectiveness of systematic use of vein conduits associated with microsurgical suture repair in SBRN injuries to prevent the occurrence of these neuromas. Our study was retrospective and performed at a single site. An independent examiner performed the clinical assessment. The study included 33 patients and the mean follow-up was 63 months...

Otitis externa is a painful condition that may require surgical intervention in dogs. A balanced analgesia protocol should combine systemic analgesic agents and local anaesthesia techniques. The aim of the study was to find anatomical landmarks for the great auricular and the auriculotemporal nerves that transmit nociceptive information from the ear pinna and to develop the optimal technique for a nerve block. The study consisted of two phases. In phase I, one fox cadaver was used for dissection and anatomical localization of the auricular nerves to derive landmarks for needle insertion...

Peripheral nerve lesions provoke apoptosis in the dorsal horn of the spinal cord. The cause of cell death, the involvement of neurons, and the relevance for the processing of somatosensory information are controversial. Here, we demonstrate in a mouse model of sciatic nerve injury that glutamate-induced neurodegeneration and loss of γ-aminobutyric acid (GABA)ergic interneurons in the superficial dorsal horn promote the transition from acute to chronic neuropathic pain. Conditional deletion of Grin1, the essential subunit of N-methyl-d-aspartate-type glutamate receptors (NMDARs), protects dorsal horn neurons from excitotoxicity and preserves GABAergic inhibition...

Optical coherence tomography angiography (OCT-A) represents the most recent tool in ophthalmic imaging. It allows for a non-invasive, depth-selective and quantitative visualization of blood flow in central retinal vessels and it has an enormous diagnostic potential not only in ophthalmology but also with regards to neurologic and systemic diseases. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary vascular small-vessel disease caused by Notch3 mutations and represents the most common form of hereditary stroke disorder...

Epithelial sheath neuroma (ESN) was first described in 2000 by Requena et al (1) as a neoplasm that clinically presents as an erythematous papule or nodule on the mid-to-upper back of middle-aged to elderly adults. ESN has been reported to be asymptomatic in some cases, while exhibiting pruritus or pain in others. (2) Histologically, ESN is described to occur in the superficial dermis and is categorized by squamous epithelium surrounding enlarged peripheral nerve fiber proliferations.
