BACKGROUND: Fecal incontinence (FI) has a multifactorial pathophysiology with a severe social impact. The most common cause for FI is pudendal nerve damage, which mostly occurs in women during or after labor. A better understanding of the pathophysiology is required to optimize treatment of FI. In this study, we evaluate the use of a novel pelvic nerve damage rat model of FI. METHODS: This new model simulates the forces on the pelvic floor during labor by prolonged transvaginal, retro-uterine intrapelvic balloon distention in female rats...

Objectives: Mandibular angle reduction or reduction genioplasty is a routine well-known facial contouring surgery that reduces the width of the lower face resulting in an oval shaped face. During the intraoral resection of the mandibular angle or chin using an oscillating saw, unexpected peripheral nerve damage including inferior alveolar nerve (IAN) damage could occur. This study analyzed cases of damaged IANs during facial contouring surgery, and asked what the basic standard of care in these medical litigation-involved cases should be...

The external branch of the superior laryngeal nerve (EBSLN) innervates the cricothyroid muscle (CTM) to promote lengthening and thinning of the vocal fold, thus increasing voice pitch. The close relation with the superior thyroid vessels (STV) puts the EBSLN in risk every time the superior pole of the thyroid is dissected. It travels downward to innervate the CTM, lateral to the thyroid cartilage and to the inferior pharyngeal constrictor muscle (IPCM), being eventually covered by this muscle fibers as it approaches its entry point...

Initially, it was believed that Aquaporin-4 (AQP4)- immunoglobulin G (IgG) only affected the central nervous system (CNS), and peripheral AQP4-expressing organs were usually spared. However, in recent years, increasing evidence has demonstrated that AQP4-IgG causes damage to peripheral organs beyond the CNS such as skeletal muscle, vestibulocochlear nerves, gastrointestinal tract, blood system, kidney, lung and placenta. Recently, the term "autoimmune aquaporin-4 channelopathy" has been proposed to incorporate a wide range of diseases associated with AQP4-IgG, including neuromyelitis optica spectrum disorders and AQP4-IgG-induced peripheral nerves system damage...

Leprosy is a chronic infectious disease with a broad spectrum of manifestations. Delays in attaining correct diagnosis permit progressive peripheral nerve damage that can produce irreversible disabilities. Tests detecting antigen-specific antibodies can aid the diagnostic process and potentially detect patients earlier. Reported tests have lacked optimal sensitivity and specificity; however, the need to develop new tests to aid early diagnosis still remains. In this study, we determined the sensitivity, specificity, positive predictive value, and negative predictive value of enzyme-linked immunosorbent assay (ELISA) using natural octyl disaccharide-leprosy IDRI diagnostic (NDO-LID)...

DNA damage response (DDR) is essential for genome stability and human health. Recently, several RNA binding proteins (RBPs), including fused-in-sarcoma (FUS), have been found unexpectedly to modulate this process. The role of FUS in DDR is closely linked to the pathogenesis of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Given that RBM45 is also an ALS-associated RBP, we wondered whether RBM45 plays any function during this process...

Gamboge is the dry resin secreted by Garcinia hanburyi Hook.f, with the function of promoting blood circulation, detoxification, hemostasis and killing insects, used for the treatment of cancer, brain edema and other diseases. Gambogic acid is the main effective constituent of Gamboge. The present study investigated the protective effects of gambogic acid on spinal cord injury (SCI) and its anti‑inflammatory mechanism in an SCI model in vivo. Basso, Beattie and Bresnahan (BBB) testing was used to detect the protective effects of gambogic acid on nerve function of SCI rats...

Spectral-domain optical coherence tomography (SDOCT), in addition to its routine clinical use in the diagnosis of ocular diseases, has begun to find increasing use in animal studies. Animal models are frequently used to study disease mechanisms as well as to test drug efficacy. In particular, SDOCT provides the ability to study animals longitudinally and non-invasively over long periods of time. However, the lack of anatomical landmarks makes the longitudinal scan acquisition prone to inconsistencies in orientation...

Dry eye disease (DED) is a common disorder causing discomfort and ocular fatigue. Corneal nerves are compromised in DED, which may further cause loss of corneal sensation and decreased tear secretion. Semaphorin 3A (Sema3A) is expressed by the corneal epithelium under stress, and is known as an inhibitor of axonal regeneration. Using a murine dry eye model, we found that topical SM-345431, a selective Sema3A inhibitor, preserved corneal sensitivity (2.3 ± 0.3 mm versus 1.4 ± 0.1 mm in vehicle control, p = 0...

We present a video of our technique for resection of a large prostatic utricle (PU) in a patient who presented initially with disordered sexual development. His karyotype was 46XY, and phenotypically had penoscrotal hypospadias, bifid scrotum, and retractile right testis. An initial micturating cystourethrogram (MCUG) demonstrated the utricle but failed to cannulate the bladder. Being asymptomatic, we carried out staged repair of his hypospadias. Later, he started to have recurrent epididymo-orchitis with resistance to multiple antibiotics...

Trigeminal nerve disorder is an important neurological sign that is often seen with multiple sclerosis (MS). We investigated eye movements in three MS patients with trigeminal disorder due to pontine lesions near the trigeminal root entry zone (REZ). Upbeat nystagmus was observed in all MS patients with trigeminal REZ lesions. We conjecture that trigeminal nerve disorder and upbeat nystagmus appeared due to simultaneous damage to both the trigeminal nerve and the vestibulo-ocular reflex pathway. If upbeat nystagmus appears in MS patients exhibiting a trigeminal nerve disorder, such as trigeminal neuralgia, and paralysis, pontine lesions near the trigeminal REZ should be considered...

Meralgia paresthetica is a non-life-threatening neurological disorder characterized by numbness, tingling, and burning pain over the anterolateral thigh due to impingement of the lateral femoral cutaneous nerve. This disorder has been seen in patients with diabetes mellitus and obesity, but has also been observed in patients after procedures such as posterior spine surgery, iliac crest bone grafts, lumbar disk surgery, hernia repair, appendectomies, and pelvic osteotomies that ultimately lead to compression or damage to the lateral femoral cutaneous nerve...

BACKGROUND: Damage of the medial prefrontal cortex (mPFC) results in similar characteristics to the cognitive deficiency seen with the progress of Parkinson's disease (PD). Since the course of mPFC damage is still unclear, our study aimed to investigate the effects of melatonin (MT) on neurotoxicity in the mPFC of a rat model of PD. METHODS: One hundred and fifty-four normal, male Wistar rats were randomly divided into the following five groups: normal + normal saline (NS), normal + 6-hydroxydopamine (6-OHDA), sham pinealectomy (PX) + 6-OHDA, PX + 6-OHDA, and MT + 6-OHDA...

Leber's hereditary optic neuropathy (LHON) is a common inherited mitochondrial disorder that is characterized by the degeneration of the optic nerves, leading to vision loss. The major mutations in the mitochondrial genes ND1, ND4, and ND6 of LHON subjects are found to increase the oxidative stress experienced by the optic nerve cell, thereby leading to nerve cell damage. Accurate treatments are not available and drugs that are commercially available like Idebenone, EPI-743, and Bendavia with their antioxidant role help in reducing the oxidative stress experienced by the cell thereby preventing the progression of the disease...

A number of nervous system disorders are characterized by a state of inflammation (neuroinflammation) in which members of the innate immune system, most notably mast cells and microglia-acting as single entities and in unison-produce inflammatory molecules that play major roles. A neuroinflammatory environment can weaken not only blood-nerve and blood-brain barrier (BBB) integrity but also that of the blood-spinal cord barrier. Mast cells, with their distribution in peripheral nerves and the central nervous system, are positioned to influence blood-nerve barrier characteristics...

Pelvic fracture is one of the common diseases of traumatic orthopedics. With the increase of accidents such as traffic accidents,high craters and crush injuries in China,the incidence of pelvic fractures is also increasing year by year. Since pelvic bones and the ligament structure are close to neurovascular,cavity organs and the urogenital structure,early diagnosis and treatment of pelvic fractures is essential for preventing early complications and late sequelae. The treatment of pelvic ring injury has been the focus of pelvic fracture treatment,which determines the outcome of treatment...
