Occipital neuralgia is a common form of headache that is characterized by paroxysmal severe lancinating pain in the occipital nerve distribution. The exact pathophysiology is still not fully understood and occipital neuralgia often develops spontaneously. There are no specific guidelines for evaluation of patients with occipital neuralgia. Cervical spine, spinal cord, and posterior neck muscle lesions can induce occipital neuralgia. Brain and spine imaging may be necessary in some cases, according to the nature of the headache or response to treatment...

Kufs disease (KD) type B (also termed CLN13), an adult-onset form of neuronal ceroid lipofuscinosis (NCL), is genetically heterogeneous and challenging to diagnose. Recently, mutations in cathepsin-F (CTSF) have been identified as the causative gene for autosomal recessive KD type B. Here, we report a sporadic case of KD type B with novel compound heterozygous mutations, a novel missense mutation c.977G>T (p.C326F) and a novel nonsense mutation c.416C>A (p.S139X), in the CTSF gene. The magnetic resonance imaging findings were consistent with those demonstrated in adult NCL: diffuse cortical atrophy, mild hyperintensity and reduction of the deep white matter on T2-weighted images...

Hai Yuan, Lingling Du, Pingping Ge, Xiaotong Wang, Qing Xia
BACKGROUND: Numerous epidemiological studies were published to investigate the role of Microtubule-Associated Protein Tau (MAPT) gene variations (rs7521G/A, rs242557G/A, rs1467967A/G, rs2471738C/T, and rs3785883G/A) in SAD, and these genetic polymorphisms may be a risk factor for sporadic Alzheimer's disease (SAD). However, controversial results were revealed. METHODS: The MEDLINE, Embase, and HuGEnet databases were searched to identify eligible studies. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the genetic association of MAPT with the risk of SAD...

BACKGROUND: Conduit-based nerve repairs are commonly used for small nerve gaps, whereas primary repair may be performed if there is no tension on nerve endings. We hypothesize a conduit-based nerve coaptation device will improve nerve repair outcomes by avoiding sutures at the nerve repair site and utilizing the advantages of a conduit-based repair. METHODS: The left sciatic nerves of female Sprague-Dawley rats were transected and repaired using a novel conduit-based device...

Lumbar spinal stenosis (LSS) is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of LSS are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of LSS and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. Specifically, we review bladder dysfunction, lower urinary tract symptoms (e.g., urinary incontinence, detrusor overactivity and under-activity, as well as frequent urinary tract infections), renal osteodystrophy, and sexual dysfunction (e...

Chih-Tsung Chang, Christina Huang
This paper studies the feasibility of frontal positioning of electrode to detect EEG signals. The proposed method involves placing a reference electrode on the forehead (Fp2) to examine visually evoked potential (VEP) signals instead of the mid-occipital electrode location (Oz) used in the traditional measurement methods. We employed widely used VEP methods, including steady-state VEP (SSVEP), flash VEP (FVEP) and Phase to investigate and compare the brain wave signals from both the Oz and Fp2 position. Traditional measurement at the Oz location are limited because of the interference from human hair, and an additional electrode is required to detect eye movement and filter this Electro-Oculogram (EOG) signal...

Systemic inflammation induced by neonatal infection may result as long-term hyperactivation of microglial cells followed by an overproduction of pro-inflammatory cytokines, such as tumor necrosis factor (TNF-α), nitric oxide (NO), and lipid peroxidation. Those inflammation mediators can trigger behavioral disruption and/or cognitive disorders. The present work aims to evaluate the effect of melatonin (a cytokine release modulator and antioxidant agent) in the reduction of the prefrontal microglia activation and depressive-like behaviors induced by LPS injection in adult rats...

INTRODUCTION: To date, there are no validated screening scales for small fiber neuropathy (SFN). This study investigated the Small-Fiber Neuropathy and Symptom Inventory Questionnaire (SFN-SIQ) as well as the Small Fiber Neuropathy Screening List (SFNSL) for SFN diagnosis. METHODS: Fifty-five patients were divided into SFN and mixed fiber damage groups. Relevant scales, nerve conduction studies (NCS) and skin biopsies were performed. Relationships between the intraepidermal nerve fiber density (IENFD) and different scales as well as the diagnostic and cut-off values (score at which Youden's index is largest) were determined...

Phrenic nerve transfer has been a well-established procedure for restoring elbow flexion function in patients with brachial plexus avulsion injury. Concerning about probably detrimental respiratory effects brought by the operation, however, stirred up quite a bit of controversy. We present a case report of the successful application of phrenic nerve as donor to reinnervate the biceps in a septuagenarian with brachial plexus avulsion injury, not accompanied with significant clinical respiratory problem.

Misfolded β-sheet structures of proteins leading to neurodegenerative diseases like Alzheimer's (AD) and Parkinson's diseases (PD) are in the spotlight since long. However, not much was known about the functional amyloids till the last decade. Researchers have become increasingly more concerned with the degree of involvement of these functional amyloids in human physiology. Interestingly, it has been found that the human body is exposed to a tremendous systemic amyloid burden, especially, during aging. Though many findings regarding these functional amyloids come up every day, some questions still remain unanswered like do these functional amyloids directly involve in the fibrillization of Amyloid beta (Aβ) 42 peptide or enhance the Aβ42 aggregation rate; whether functional bacterial amyloids (FuBA) co-localize with the senile plaques of AD or not...

We reported a misdiagnosed case of a 66-year-old man who concomitantly developed chronic inflammatory demyelinating polyneuropathy (CIDP) and myasthenia gravis (MG), which was rarely reported. This man presented with chronic progressive sensory symptoms, flaccid tetraparesis, areflexia and protein-cell dissociation of cerebrospinal fluid. Nerve conduction study was indicative of demyelinating neuropathy. He was suspected as CIDP and treated with high-dose glucocorticoids. However, his condition worsened. Four months later, he was admitted and was diagnosed as combination of CIDP and MG...

Induction of endogenous antioxidants is one of the key molecular mechanisms of cell resistance to hypoxia/ischemia. Thioredoxin1 (Trx1) is a small multifunctional ubiquitous antioxidant with redox-active dithiol and plays an important role in cell apoptosis through mitochondrial apoptosis pathways. The specific role of Trx1 in ischemia-reperfusion induced astrocyte apoptosis, however, remains unclear. In this study, we investigated the effect of Trx1 on apoptosis of astrocyte using an in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) model which mimics ischemic/reperfusion conditions in vivo...
