    2014-01-01

    PURPOSE: The primary purpose of this study was to analyze the rate, pattern, and severity of symptoms of nerve dysfunction after hip arthroscopy (HA) by reviewing prospectively collected data. The secondary purpose was to study whether symptoms of nerve dysfunction were related to traction time...... year after HA concerning symptoms of nerve dysfunction, possible localization, and erectile dysfunction. Fifty patients participated and returned fully completed questionnaires. Patients reporting symptoms of nerve dysfunction 1 year after HA were re-examined. RESULTS: Twenty-three of 50 patients (46......%) reported symptoms of nerve dysfunction during the first week after HA; this was reduced to 14 patients (28%) after 6 weeks, 11 patients (22%) after 26 weeks, and 9 patients (18%) after 1 year. One patient experienced temporary erectile dysfunction. No difference in traction time between patients...

    Skull base metastases are challenging situations because they often involve critical structures such as cranial nerves. We evaluated the role of stereotactic radiotherapy (SRT) which can give high doses to the tumors sparing normal structures. We treated 11 cases of skull base metastases from other visceral carcinomas. They had neurological symptoms due to cranial nerve involvement including optic nerve (3 patients), oculomotor (3), trigeminal (6), abducens (1), facial (4), acoustic (1), and lower cranial nerves (1). The interval between the onset of cranial nerve symptoms and Novalis SRT was 1 week to 7 months. Eleven tumors of 8-112 ml in volume were treated by Novalis SRT with 30-50 Gy in 10-14 fractions. The tumors were covered by 90-95% isodose. Imaging and clinical follow-up has been obtained in all 11 patients for 5-36 months after SRT. Seven patients among 11 died from primary carcinoma or other visceral metastases 9-36 months after Novalis SRT. All 11 metastatic tumors were locally controlled until the end of the follow-up time or patient death, though retreatment for re-growth was done in 1 patient. In 10 of 11 patients, cranial nerve deficits were improved completely or partially. In some patients, the cranial nerve symptoms were relieved even during the period of fractionated SRT. Novalis SRT is thought to be safe and effective treatment for skull base metastases with involvement of cranial nerves and it may improve cranial nerve symptoms quickly.

    Full Text Available Entrapment of a nerve in the callus of a healing fracture is not a common entity, but it does exist. The entrapment usually presents without neurological deficit. It is difficult to suspect the radial nerve injury if we need to operate on the same site. We present a case of entrapment of radial nerve in the callus of a supracondylar humerus fracture with cubitus varus deformity. The surgery for correction of the deformity led to the damage of the nerve. In retrospect a careful assessment of the x-rays showed two 3-4 mm diameter holes. Awareness of this finding would have given us sufficient indication of nerve entrapment to prevent this mishap.

    To assess and grade facial nerve dysfunction according to the extent of facial paralysis in the clinical course of acupuncture treatment for Bell's palsy, and to observe the interrelationship between the grade, the efficacy and the period of treatment, as well as the effect on prognosis. The authors employed the House-Brackmann scale, a commonly used evaluation scale for facial paralysis motor function, and set standards for eye fissure and lips. According to the improved scale, the authors assessed and graded the degree of facial paralysis in terms of facial nerve dysfunction both before and after treatment. The grade was divided into five levels: mild, moderate, moderately severe, severe dysfunction and complete paralysis. The authors gave acupuncture treatment according to the state of the disease without artificially setting the treatment period. The observation was focused on the efficacy and the efficacy was evaluated throughout the entire treatment process. Fifty-three cases out of 68 patients with Bell's palsy were cured and the overall rate of efficacy was 97%. Statistically significant differences (Pfacial nerve dysfunction. Efficacy was correlated with the damage level of the disease (correlation coefficient r=0.423, Pfacial nerve dysfunction (Pfacial nerve dysfunction. Efficacy is reduced in correlation with an increase in facial nerve dysfunction, and the period of treatment varies in need of different levels of facial nerve dysfunction. It is highly necessary to assess and grade patients before observation and treatment in clinical study, and choose corresponding treatment according to severity of damage of the disease.

    Full Text Available Abstract Background In a previous study of computer operators we have demonstrated the relation of upper limb pain to individual and patterns of neurological findings (reduced function of muscles, sensory deviations from normal and mechanical allodynia of nerve trunks. The identified patterns were in accordance with neural afflictions at three specific locations (brachial plexus at chord level, posterior interosseous and median nerve on elbow level. We have introduced an intervention program aiming to mobilize nerves at these locations and tested its efficacy. Methods 125 and 59, respectively, computer operators in two divisions of an engineering consultancy company were invited to answer a questionnaire on upper limb symptoms and to undergo a blinded neurological examination. Participants in one division were subsequently instructed to participate in an upper limb stretching course at least three times during workdays in a six month period. Subjects from the other division served as controls. At the end of the intervention both groups were invited to a second identical evaluation by questionnaire and physical examination. Symptoms and findings were studied in the right upper limb. Perceived changes of pain were recorded and individual and patterns of physical findings assessed for both groups at baseline and at follow-up. In subjects with no or minimal preceding pain we additionally studied the relation of incident pain to the summarized findings for parameters contained in the definition of nerve affliction at the three locations. Results Summarized pain was significantly reduced in the intervention group but unchanged in controls. After the intervention, fewer neurological abnormalities in accordance with nerve affliction were recorded for the whole material but no conclusion could be drawn regarding the relation to the intervention of this reduction. Incident pain correlated to findings in accordance with the three locations of nerve

    One of the shortcomings of current treatment of nerve agent poisoning is that oximes hardly penetrate the blood brain barrier (BBB), whereas nerve agents easily do. Enhancing the efficacy of current oximes in the brain, would therefore provide an attractive approach to improve medical countermeasure

    Full Text Available Abstract Background There are controversial results on the efficacy of the abandoned, intrathecal predominant methylprednisolone application in multiple sclerosis (MS in contrast to the proven effectiveness in intractable postherpetic neuralgia. Methods We performed an analysis of the efficacy of the application of 40 mg of the sustained release steroid triamcinolone acetonide (TCA. We intrathecally injected in sterile saline dissolved TCA six times within three weeks on a regular basis every third day in 161 hospitalized primary and predominant secondary progressive MS patients with spinal symptoms. The MS patients did not experience an acute onset of exacerbation or recent distinct increased progression of symptoms. We simultaneously scored the MS patients with the EDSS and the Barthel index, estimated the walking distance and measured somatosensory evoked potentials. Additionally the MS patients received a standardized rehabilitation treatment. Results EDSS score and Barthel index improved, walking distance increased, latencies of somatosensory evoked potentials of the median and tibial nerves shortened in all MS patients with serial evaluation (p Conclusions Repeated intrathecal TCA application improves spinal symptoms, walking distance and SSEP latencies in progressive MS patients in this uncontrolled study. Future trials should evaluate the long-term benefit of this invasive treatment.

    BACKGROUND: Pattern- visual evoked potential (PVEP) can reflect the functional status of retinal ganglial cells (RGC) and visual cortex, and is an objective examination for visual pathway function. It is a unique method for objectively examining the optic nerve function of optic ganglion cells.OBJECTIVE: To observe the effects of nerve growth factor (NGF) on PVEF in the treatment of optic nerve contusion, evaluate the clinical efficacy of NGF, and make an efficacy comparison with vitamin B12.DESIGN: A randomly grouping, controlled observation.SETTING: Department of Ophthalmology, Tangshan Gongren Hospital Affiliated to Hebei Medical University.PARTICIPANTS: Forty patients with optic nerve contusion caused by eye trauma, who received the treatment in the Tangshan Worker Hospital Affiliated to Hebei Medical University between January 2006 and June 2007, were recruited in this study. The involved 40 patients, including 34 males and 6 females,were aged 14 - 59 years. They were confirmed to have optic nerve contusion by ophthalmologic consultation combined with history of disease and orbital CT examination. Informed consents of treatments and detected items were obtained from all the patients. The patients were randomly divided into 2 groups with 20 in each:NGF group and vitamin B12 group.METHODS: Conservative treatment was used in the two groups. In addition, patients in the NGF group were intramuscularly injected with NGF solution 18 μg/time, once a day. Those in the vitamin B12 group were injected by the same method with common vitamin B12 of 500 μg combined with vitamin B1 of 100 mg, once a day.MAIN OUTCOME MEASURES: PVEP examination was conducted in all the patients before, one and two weeks after treatment, and latency and amplitude at P100 were detected.RESULTS: Forty patients with optic nerve contusion participated in the final analysis. Before treatment,significant differences in the latency and amplitude at P100 were not found in patients between two groups

    Standard treatment of poisoning by organophosphorus compounds (OP) includes the administration of an anti-muscarinic, e.g. atropine, and of an acetylcholinesterase (AChE) reactivator (oxime). Two oximes, obidoxime and pralidoxime (2-PAM), are presently commercially available, yet, these compounds are considered to be of insufficient efficacy against certain nerve agents, e.g. soman and cyclosarin. In the past decades, numerous new oximes were synthesized and tested for their antidotal efficacy. The available data indicate that two Hagedorn oximes, HI 6 and HLö 7, are promising antidotes against various nerve agents. The efficacy of antidotes against nerve agent poisoning cannot be investigated in humans for ethical reasons. Therefore, it is necessary to use surrogate parameters for the evaluation of oxime efficacy. Reactivation of inhibited AChE is considered to be the main mechanism of action of oximes. Clinical data indicate that changes in erythrocyte AChE activity correlate to neuromuscular function indicating that interactions between AChE, inhibitor and oximes can be investigated in vitro with human erythrocyte AChE. Different theoretical models were used for the evaluation of reactivating efficacy of oximes with nerve agent-inhibited human AChE and for estimating effective oxime concentrations. The calculations demonstrate the marked differences between oximes in dependence of the inhibitor and provide a basis for the estimation of the required oxime dose as well as of dosing intervals.

    To study the clinical efficacy of mouse nerve growth factor (NGF) in the treatment of sudden deafness. A retrospective analysis was performed on 115 cases of hospitalized patients who were suffered from sudden deafness. Patients were divided into two groups according to treatment medicine. Control group: patients were treated with intravenous vasodilators, energy mixture, steroid pulse therapy, and methylcobalamin neurotrophic therapy. NGF group: intramuscular NGF treatment was added on the basis of conventional therapy mentioned above. Both treatments lasted 14 days, the total efficiency were compared. Patients were further divided into sub-groups according to age, duration and the level of pre-treatment PTA, and the treatment efficiency was further compared. By SPSS 11.0 statistical analysis, a P 60 dBHL, the efficiency of NGF therapy was not superior to the traditional treatment. NGF can significantly improve the symptom of patients with short duration or low PTA. For this kind of patients, NGF adjuvant therapy should be recommended. For the patients with longer duration and higher level of PTA, NGF therapy is not advocated. NGF treatment should not be in consideration of the age.

    Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Our patient presented with radicular symptoms involving the left hand. Imaging workup revealed a cystic lesion of the left T1 nerve root at the level of the foramen. Surgical resection resulted in significant improvement in patient symptoms, and pathology revealed a perineural cyst. We conclude that a thoracic perineural (Tarlov) cyst can be symptomatic by causing nerve root compression and can be mistaken as a nerve root sheath tumor on imaging. Surgical treatment can be curative.

  18. Minimally invasive endoscopic ulnar nerve assessment and surgery for cubital tunnel syndrome patients—Relation between endoscopic nerve findings and clinical symptoms

    Full Text Available To minimize damage to healthy tissues, we have been performing endoscopically assisted cubital tunnel syndrome surgery based on endoscopic nerve findings since 1995. This is the first study to focus on endoscopic surgery for cubital tunnel syndrome based on endoscopic ulnar nerve findings and the subsequent postoperative clinical results. We analysed 82 upper extremities of 74 cubital tunnel syndrome patients who had undergone endoscopically assisted release surgery using the Universal Subcutaneous Endoscope system. Endoscopic observations of the ulnar nerve were made from a single 1- to 3-cm endoscopic portal incision at the cubital tunnel to 10 cm proximal and 10 cm distal. The abnormal nerve areas were identified and released based on nerve degeneration findings under endoscopic observation. The abnormal areas spread eccentrically from the entrapment point(s. In 82 diseased upper extremities, ulnar nerve entrapment occurred at the cubital tunnel. However, one extremity suffered from entrapment at the arcade of Struthers' in addition to the cubital tunnel. All patients showed improved clinical symptoms following surgery. There is no statistical relation between pre- and postoperative clinical scores of Dellon's Staging and abnormal nerve length findings. Cubital tunnel syndrome is usually caused by entrapment at the cubital tunnel; however, in some cases, there are other point entrapment(s. Our endoscopically assisted procedure avoids any damage to healthy tissues because the surgeon can observe the entrapment point(s prior to release. Postoperative clinical recovery results clearly indicate that endoscopic nerve findings reveal entrapment points and ulnar nerve degeneration can spread maximally 10 cm distally and proximally from the entrapment point(s, even in clinically mild severity cases. All other possible entrapment points should, therefore, be observed and released using our procedure.

    Full Text Available Background: During transurethral resection surgery (TUR, accidental stimulation of the obturator nerve can cause violent adductor contraction, leading to serious intraoperative complications. General anesthesia with muscle relaxation is currently the preferred technique for TUR surgery. Spinal anesthesia combined with obturator nerve block has also been used for TUR surgery in geriatric population. Blind, anatomical methods for identifying the obturator nerve are often unsatisfactory. Therefore, we conducted this prospective study to validate the efficacy of ultrasound-guided obturator nerve block (USONB during TUR procedures. Methods: Eighteen male patients undergoing TURP surgery under spinal anesthesia were included in the study. Bilateral USONB with maximum 20 ml of 1% lidocaine per patient was performed. An independent observer was present to monitor any adduction movements during the operation and to record patient and surgeon satisfactions. Results: In all patients, obturator nerve was visualized from the first attempt, requiring an average of 4.3 min for blocking of each side. USONB was successful (97.2% in preventing an adductor spasm in all except one patient. Patient′s and surgeon′s satisfaction were appropriate. In all patients, adductor muscle strength recovered fully within 2 h following the surgical procedure. Conclusions: USONB is safe and effective during TUR surgery. It provides optimal intra-and postoperative conditions.

    Background Although autologous nerve grafting is the gold standard treatment of peripheral nerve injuries, several alternative methods have been developed, including nerve conduits that use supportive cells. However, the seeding efficacy and viability of supportive cells injected in nerve grafts remain unclear. Here, we focused on a novel completely biological, tissue-engineered, scaffold-free conduit. Methods We developed six scaffold-free conduits from human normal dermal fibroblasts using a Bio 3D Printer. Twelve adult male rats with immune deficiency underwent mid-thigh-level transection of the right sciatic nerve. The resulting 5-mm nerve gap was bridged using 8-mm Bio 3D conduits (Bio 3D group, n = 6) and silicone tube (silicone group, n = 6). Several assessments were conducted to examine nerve regeneration eight weeks post-surgery. Results Kinematic analysis revealed that the toe angle to the metatarsal bone at the final segment of the swing phase was significantly higher in the Bio 3D group than the silicone group (-35.78 ± 10.68 versus -62.48 ± 6.15, respectively; p < 0.01). Electrophysiological studies revealed significantly higher compound muscle action potential in the Bio 3D group than the silicone group (53.60 ± 26.36% versus 2.93 ± 1.84%; p < 0.01). Histological and morphological studies revealed neural cell expression in all regions of the regenerated nerves and the presence of many well-myelinated axons in the Bio 3D group. The wet muscle weight of the tibialis anterior muscle was significantly higher in the Bio 3D group than the silicone group (0.544 ± 0.063 versus 0.396 ± 0.031, respectively; p < 0.01). Conclusions We confirmed that scaffold-free Bio 3D conduits composed entirely of fibroblast cells promote nerve regeneration in a rat sciatic nerve model. PMID:28192527

    The aims of this study were to examine differences in self-schemas between persons living with HIV/AIDS with and without depressive symptoms, and the degree to which these self-schemas predict depressive symptoms in this population. Self-schemas are beliefs about oneself and include self-esteem, HIV symptom management self-efficacy, and self-compassion. Beck's cognitive theory of depression guided the analysis of data from a sample of 1766 PLHIV from the USA and Puerto Rico. Sixty-five percent of the sample reported depressive symptoms. These symptoms were significantly (p ≤ 0.05), negatively correlated with age (r = -0.154), education (r = -0.106), work status (r = -0.132), income adequacy (r = -0.204, self-esteem (r = -0.617), HIV symptom self-efficacy (r = - 0.408), and self-kindness (r = - 0.284); they were significantly, positively correlated with gender (female/transgender) (r = 0.061), white or Hispanic race/ethnicity (r = 0.047) and self-judgment (r = 0.600). Fifty-one percent of the variance (F = 177.530 (df = 1524); p self-esteem, HIV symptom self-efficacy, and self-judgment. The strongest predictor of depressive symptoms was self-judgment. Results lend support to Beck's theory that those with negative self-schemas are more vulnerable to depression and suggest that clinicians should evaluate PLHIV for negative self-schemas. Tailored interventions for the treatment of depressive symptoms in PLHIV should be tested and future studies should evaluate whether alterations in negative self-schemas are the mechanism of action of these interventions and establish causality in the treatment of depressive symptoms in PLHIV.

    The purpose of this study was to evaluate the effect of submucous tramadol as adjuvant of mepivacaine with epinephrine in inferior alveolar nerve block. A double-blind, randomized, placebo-controlled, crossover clinical trial was conducted. Twenty healthy young volunteers were randomized into two treatment sequences using a series of random numbers. Sequence 1: Group A, 2% mepivacaine with 1:100,000 epinephrine plus submucous tramadol 50mg (1mL of saline) and one week later Group B, 2% mepivacaine with 1:100,000 epinephrine plus submucous placebo (1mL of saline). Sequence 2: Group B and one week later Group A. All treatments were administered 1min after that patient informed anesthesia of lower lip. We evaluated the duration of anesthesia of lower lip, anesthetic efficacy, and local and systemic adverse events. Anesthetic efficacy was better in group receiving submucous tramadol during the first 2h compared with group receiving submucous placebo (Pmepivacaine with epinephrine of soft tissue in inferior alveolar nerve block.

    Facial flushing in rosacea is often induced by trigger events. However, trigger causation mechanisms are currently unclear. This study tested the central hypothesis that rosacea causes sympathetic and axon reflex-mediated alterations resulting in trigger-induced symptomatology. Twenty rosacea patients and age/sex-matched controls participated in one or a combination of symptom triggering stressors. In protocol 1, forehead skin sympathetic nerve activity (SSNA; supraorbital microneurography) was measured during sympathoexcitatory mental (2-min serial subtraction of novel numbers) and physical (2-min isometric handgrip) stress. In protocol 2, forehead skin blood flow (laser-Doppler flowmetry) and transepithelial water loss/sweat rate (capacitance hygrometry) were measured during sympathoexcitatory heat stress (whole body heating by perfusing 50°C water through a tube-lined suit). In protocol 3, cheek, forehead, forearm, and palm skin blood flow were measured during nonpainful local heating to induce axon reflex vasodilation. Heart rate (HR) and mean arterial pressure (MAP) were recorded via finger photoplethysmography to calculate cutaneous vascular conductance (CVC; flux·100/MAP). Higher patient transepithelial water loss was observed (rosacea 0.20 ± 0.02 vs. control 0.10 ± 0.01 mg·cm(-2)·min(-1), P rosacea and controls, respectively) stress was augmented in rosacea (both P rosacea compared with controls. No axon reflex vasodilation differences were observed between groups. These data indicate that rosacea affects SSNA and that hyperresponsiveness to trigger events appears to have a sympathetic component.

    Against highly toxic chemicals that are quickly absorbed in the skin, topical formulations could adequately complement specific protective suits and equipments. In this work, we evaluated in vitro and compared the skin protection efficacy against the nerve agent VX of four different topical formulations: oil-in-water and water-in-oil emulsions, a perfluorinated-based cream and a hydrogel. Semi-permeable silicone membrane, pig-ear and human abdominal split-thickness skin samples mounted in diffusion cells were compared as in vitro permeation tests. The results showed that silicone membrane could be used instead of skin samples to screen for potentially effective formulations. However, the results indicated that due to potentially significant interactions between formulations and skin, relevant ranking of formulations according to their protective efficacy could require tests with skin samples. The main phase of emulsions, water or oil, was not found to be critical for skin protective efficacy against VX. Instead, specific film-forming ingredients such as perfluorinated-based polymers and silicones could significantly affect the skin protective efficacy of formulations. We showed that a hydrogel containing specific hydrophilic polymers was by far the most effective of the formulations evaluated against VX skin permeation in vitro.

    This study examined self-efficacy for managing pain, symptoms, and function in patients with lung cancer and their caregivers, and associations between self-efficacy and patient and caregiver adjustment. One hundred and fifty-two patients with early stage lung cancer completed measures of self-efficacy, pain, fatigue, quality of life, depression, and anxiety. Their caregivers completed a measure assessing their self-efficacy for helping the patient manage symptoms and measures of psychological distress and caregiver strain. Analyses indicated that, overall, patients and caregivers were relatively low in self-efficacy for managing pain, symptoms, and function, and that there were significant associations between self-efficacy and adjustment. Patients low in self-efficacy reported significantly higher levels of pain, fatigue, lung cancer symptoms, depression, and anxiety, and significantly worse physical and functional well being, as did patients whose caregivers were low in self-efficacy. When patients and caregivers both had low self-efficacy, patients reported higher levels of anxiety and poorer quality of life than when both were high in self-efficacy. There were also significant associations between patient and caregiver self-efficacy and caregiver adjustment, with lower levels of self-efficacy associated with higher levels of caregiver strain and psychological distress. These preliminary findings raise the possibility that patient and caregiver self-efficacy for managing pain, symptoms, and function may be important factors affecting adjustment, and that interventions targeted at increasing self-efficacy may be useful in this population.

    Full Text Available Jing Wan Hong ointment contains 30 kinds of Chinese herbs, with functions of activating blood circulation to disperse blood stasis, clearing heat, eliminating dampness, and reducing swelling by detoxification. Therefore, Jing Wan Hong ointment may facilitate the healing of ulcers. The aim of this study was to evaluate the efficacy and mechanisms of Jing Wan Hong ointment for healing diabetic foot ulceration in Wistar rats induced by streptozotocin and sciatic nerve damage. The results showed that Jing Wan Hong ointment had a marked effect on foot ulcers in diabetic rats induced by initial nerve injury. These effects were manifested by reducing the foot ulcer size and Wagner grade after seven days of treatment. The diabetic rats with foot ulcers were almost healed after 21 days of treatment. Moreover, the mechanisms of this effect seem to be dependent on increased expression of PDGF mRNA, but there was no influence on the expression of TGF-β, VEGF, and FLT-1 mRNA.

    Intoxication by organophosphorus compounds, especially by pesticides, poses a considerable risk to the affected individual. Countermeasures involve both medical intervention by means of antidotes as well as external decontamination to reduce the risk of dermal absorption. One of the few decontamination options available is Reactive Skin Decontamination Lotion (RSDL), which was originally developed for military use. Here, we present a (31)P NMR spectroscopy based methodology to evaluate the detoxification efficacy of RSDL with respect to a series of organophosphorus pesticides and nerve agents. Kinetic analysis of the obtained NMR data provided degradation half-lives proving that RSDL is also reasonably effective against organophosphorus pesticides. Unexpected observations of different RSDL degradation patterns are presented in view of its reported oximate-catalyzed mechanism of action.

    Full Text Available There is a lack of research investigating community-level characteristics, such as community collective efficacy, mitigating the impact of disasters on psychological health, specifically depression. We examined the association of community collective efficacy with depressive symptom severity in Florida public health workers (n = 2249 exposed to the 2004 hurricane season using a multilevel approach. Cross-sectional anonymous questionnaires were distributed electronically to all Florida Department of Health (FDOH personnel that assessed depressive symptom severity and collective efficacy nine months after the 2004 hurricane season. Analyses were conducted at the individual level and community level using zip codes. The majority of participants were female (81.9%, and ages ranged from 20 to 78 years (median = 49 years. The majority of participants (73.4% were European American, 12.7% were African American, and 9.2% were Hispanic. Using multilevel analysis, our data indicate that higher community-level and individual-level collective efficacy were associated with significantly lower depressive symptom severity (b = -0.09 [95% CI: -0.13, -0.04] and b = -0.09 [95% CI: -0.12, -0.06], respectively even after adjusting for individual sociodemographic variables, community socioeconomic characteristics, individual injury/damage, and community storm damage. Lower levels of depressive symptom severity were associated with communities with high collective efficacy. Our study highlights the possible importance of programs that enrich community collective efficacy for disaster communities.

    Acupuncture is one of the important parts of therapeutic methods in traditional Chinese medicine, and has been widely used for the treatment of nerve deafness in recent years. The current study was to evaluate the efficacy and safety of acupuncture therapy for nerve deafness compared with conventional medicine therapy. PubMed, the Chinese National Knowledge Infrastructure Database, the Chinese Science and Technology Periodical Database, the Chinese Biomedical Database, the Wanfang Database were searched for articles published to identify randomized controlled trials evaluating efficacy and side effects between acupuncture and conventional medicine therapies up to 2013/06. A total of 12 studies, including 527 patients assessed the efficacy and safety of acupuncture therapy for nerve deafness. Overall, the efficacy of acupuncture was significantly better than that of the conventional western medication (RR: 1.54, 95% CI: 1.36-1.74) or traditional Chinese medicines (RR: 1.51, 95% CI: 1.24-1.84), and the efficacy of acupuncture in combination with conventional western medication or traditional Chinese medicine was better than that of the conventional western medication alone (RR: 1.51, 95% CI: 1.29-1.77) or traditional Chinese medicine alone (RR: 1.59, 95% CI: 1.30-1.95). Based on the comparison of number of deafness patients who were completely cured, the efficacy of acupuncture in combination with traditional Chinese medicines was better than that of traditional Chinese medicine alone (RR: 4.62, 95% CI: 1.38-15.47). Acupuncture therapy can significantly improve the hearing of patients with nerve deafness, and the efficacy of acupuncture in combination with medication is superior to medication alone.

    Understanding the variables that contribute to the comorbidity of depression and gambling behaviors is important in developing effective intervention strategies for those who experience gambling-related problems. The purpose of this study was to implement core concepts from Jacob's general theory of addiction and the social cognitive theory in a multiple mediation model. Specifically, we tested two models to examine whether coping motivation and refusal self-efficacy mediated the relationship between depressive symptoms, gambling related problems, and days gambled. Data was collected from 333 undergraduate students at a large public Midwest university, participating in a larger clinical trial. Analyses indicated a direct effect between depressive symptoms and gambling related problems. Depressive symptoms were found to have a significant indirect effect through coping motivation and gambling refusal self-efficacy on gambling related problems and days gambled. These results provide further support regarding the mechanisms through which depressive symptoms may increase risk for problematic gambling behavior.

    2016-01-01

    Introduction Overactive Bladder (OAB) accounts for 40-70% cases of incontinence. The etiology is unknown though detrusor instability is found in urodynamic evaluation of almost all cases. Detrusor instability or hyperreflexia can be inhibited by direct inhibition of impulses in the pre-ganglionic afferent neuron or by inhibition of bladder pre-ganglionic neurons of the efferent limb of micturition reflex. Transcutaneous Electrical Nerve Stimulation (TENS) is based on the gate control theory of abolishing the local micturition reflex arc. Aim To assess the effectiveness and safety of TENS in idiopathic OAB. Materials and Methods It is a prospective experimental study to evaluate the effectiveness of TENS v/s placebo in reducing OAB symptoms. (n1=20, n2 =20). Ten treatment sessions (5 sessions/week) of 30 minutes, were conducted. Results There was a significant improvement in Overactive Bladder Symptom Scores (OABSS) in TENS group and 2 patients were completely dry following TENS therapy. Conclusion In elderly women, patients with OAB where other co-medications have their own anticholinergic side effects and impairment of cognition is a concern, TENS can be a useful intervention. TENS units are safe, economical and easily commercially available. PMID:27891403

    Full Text Available Objective: To evaluate the clinical efficacy of transcutaneous electric nerve stimulation in the treatment of postoperative knee arthroplasty pain and to relate these results to the stimulation parameters used. Data Sources: PubMed, Pedro and Web of Knowledge were systematically screened for studies investigating effects of transcutaneous electric nerve stimulation on postoperative knee arthroplasty pain. Review Methods: Studies were screened for their methodological and therapeutical quality. We appraised the influence of the stimulation settings used and indicated whether or not a neurophysiological and/or mechanistic rationale was given for these stimulation settings. Results: A total of 5 articles met the inclusion criteria. In total, 347 patients were investigated. The number of patients who received some form of transcutaneous electric nerve stimulation was 117, and 54 patients received sham transcutaneous electric nerve stimulation. Pain was the primary outcome in all studies. The stimulation settings used in the studies (n = 2 that reported significant effects differed from the others as they implemented a submaximal stimulation intensity. Stimulation parameters were heterogeneous, and only one study provided a rationale for them. Conclusion: This review reveals that an effect of transcutaneous electric nerve stimulation might have been missed due to low methodological and therapeutical quality. Justifying the choice of transcutaneous electric nerve stimulation parameters may improve therapeutical quality.

    Gastrointestinal symptoms are a problematic issue for patients who take low-dose aspirin for long time. We conducted a pilot study to investigate the efficacy of combination therapy with proton pump inhibitor and rebamipide. This was a prospective, randomized, double-blind, placebo-controlled cross-over study. All the subjects received aspirin 100 mg and omeprazole 20 mg. The subjects were divided into two groups and received either rebamipide 300 mg or placebo, which was prescribed for 4 weeks. The subjects were instructed to record their gastrointestinal symptom rating scale before the study and 1 and 4 weeks after beginning the protocol. These scores of the groups were compared before and after the treatment to evaluate the severity of their symptoms and the number of symptom items present in each group. For the subjects receiving rebamipide, the total prevalence of lower gastrointestinal symptoms was significantly different from the placebo group (p=0.0093) at week 4. No troublesome symptoms were observed in the rebamipide group. Inconclusion, the administration of rebamipide prevented the occurrence of troublesome symptoms, especially lower gastrointestinal symptoms, in patients taking aspirin and omeprazole. Rebamipide is a candidate drug for combination therapy with proton pump inhibitors to prevent low-dose aspirin-induced gastrointestinal symptoms.

    Full Text Available Biofeedback therapy is a well-known and effective therapeutic treatment for constipation. A previous study suggested that adaptive biofeedback (ABF training was more effective than traditional (fixed training parameters biofeedback training. The aim of this study was to verify the effectiveness of ABF in relieving constipation-related symptoms. We noticed that in traditional biofeedback training, a patient usually receives the training twice per week. The long training sessions usually led to poor compliance. This study proposes an intensive biofeedback therapy and compares intensive therapy with nonintensive therapy in patients with constipation-related symptoms. Methods. 63 patients with constipation-related symptoms were treated with ABF between 2012 and 2013. These patients were further divided into the intensive therapy and nonintensive therapy groups. Results. A total of 63 patients were enrolled in the study, including 24 in the nonintensive therapy group and 39 in the intensive therapy group. 100% (N=21 of constipation patients achieved the primary efficacy endpoint (≥3 bowel movements/week. There was significant improvement in constipation-related symptoms after adaptive biofeedback. The intensive biofeedback therapy did not show better performance compared to nonintensive biofeedback therapy. Conclusions. This investigation provides support for the efficacy of biofeedback for constipation-related symptoms. The efficacy of intensive therapy is similar to nonintensive therapy.

    Vilazodone is a potent selective serotonin reuptake inhibitor and serotonin 1A receptor partial agonist approved for the treatment of major depressive disorder in adults. To assess the efficacy of vilazodone across a range of symptoms and severities of depression, data from two phase III, 8-week, randomized, double-blind, placebo-controlled trials were pooled for analysis. Overall improvement in depressive symptoms measured using the Montgomery-Åsberg Depression Rating Scale (MADRS) and the 17-item Hamilton Depression Rating Scale was statistically significant (Pdepression subgroups, with no consistent pattern associated with depression severity. These findings support the efficacy of vilazodone across a broad range of depressive symptoms and severities for the treatment of major depressive disorder.

    2016-12-01

    Full Text Available Background and Objective:Radiographic assessment before third molar surgery allows the surgeon to consider any essential modifications in the surgical practice, thus minimizing the risk of damage to the inferior alveolar nerve. This study attempted to evaluate the association between radiographic evidence of inferior alveolar nerve involvement on the preoperative panoramic radiograph and its clinical symptoms during and after mandibular third molar surgery. Materials and Methods:In this cross-sectional study 464 patients went through panoramic radiography, examined by an oral and maxillofacial radiologist. Then, the relationship between the third molar's root and inferior alveolar nerve was determined. Furthermore, the data obtained from each patient such as intraoperative (canal bleeding or nerve exposure and postoperative (neurosensory deficit complications were recorded. At the next stage, data were analyzed by SPSS 20 and Fisher’s exact test. Results: The study consisted of 464 patients. 209 (45% patients out of 464 were suspected of having molarcanal contacts, 143 were observed to have loss of tramlines, 138 cases of which were partial and 118 had no upper canal border. In terms of clinical symptoms during surgery, 445 patients (95.9% showed no involvement while 6 patients (1.3% had postoperative paresthesis. Moreover, 8.6% of patients suspected of molar-canal contacts based on radiographic images demonstrated clinical symptoms of intraoperative nerve involvement. However, there was no significant relationship between radiographic findings and symptoms of postoperative nerve deficit (p=0.095. Conclusion: The results demonstrated there is a relationship between radiographic evidence of nerve-canal contact and intraoperative clinical symptoms. Moreover, panoramic radiographs cannot provide a useful tool to predict the risk of postoperative nerve paresthesia.

    Our previous studies have histomorphological y confirmed that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit can be used to repair 30-mm-long sciatic nerve defects. However, the repair effects on rat behaviors remain poorly understood. In this study, we used nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous sciatic nerve to bridge 30-mm-long rat sciatic nerve gaps. Within 4 months after surgery, rat sciatic nerve functional re-covery was evaluated per month by behavioral analyses, including toe out angle, toe spread anal-ysis, walking track analysis, extensor postural thrust, swimming test, open-field analysis and noci-ceptive function. Results showed that rat sciatic nerve functional recovery was similar after nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous nerve grafting. These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit is suitable in use for repair of long-segment sciatic nerve defects.

    Background In general vagus nerve stimulation (VNS) can serve as an adjunctive treatment for patients with refractory partial -onset seizures. And we evaluated the long-term efficacy and safety of VNS in a group of Chinese patients with refratory epilepsy.Methods Of 127 patients with refractory epilepsy, 13 patients who were not eligible for surgical intervention were implanted with the Cyberonics VNS system. Seizure frequency, physical examination and side effects profile were recorded at follow-up visits for a minimum of 18 months.Results Mean duration of treatment was 47.4 months, and the longest follow-up period was 71 months. Mean baseline seizure frequency was 26.6 seizures per month. The mean percentage reductions in convulsions were 33.2%, 47.1% and 40.0% at 6, 12 and 18 months, respectively. One patient became seizure free, and six (46%) had 50% or more reduction in seizure frequency. Response was poor (<20% reduction) in five patients (39%). Side effects were uncommon.Conclusions The effectiveness of VNS was sustained and was well tolerated but benefited only a sub-group of patients with intractable convulsions.

    The nerve agent VX is most likely to enter the body via liquid contamination of the skin. After percutaneous exposure, the slow uptake into the blood, and its slow elimination result in toxic levels in plasma for a period of several hours. Consequently, this has implications for the development of toxic signs and for treatment onset. In the present study, clinical signs, toxicokinetics and effects on respiration, electroencephalogram and heart rate were investigated in hairless guinea pigs after percutaneous exposure to 500 microg/kg VX. We found that full inhibition of AChE and partial inhibition of BuChE in blood were accompanied by the onset of clinical signs, reflected by a decline in respiratory minute volume, bronchoconstriction and a decrease in heart rate. Furthermore, we investigated the therapeutic efficacy of a single dose of atropine, obidoxime and diazepam, administered at appearance of first clinical signs, versus that of repetitive dosing of these drugs on the reappearance of signs. A single shot treatment extended the period to detrimental physiological decline and death for several hours, whereas repetitive administration remained effective as long as treatment was continued. In conclusion, percutaneous VX poisoning showed to be effectively treatable when diagnosed on time and when continued over the entire period of time during which VX, in case of ineffective decontamination, penetrates the skin.

    The purpose of this study was to assess the 1-year maintenance of the efficacy of desvenlafaxine 100 mg/day (administered as desvenlafaxine succinate) established on week 12 in a 1-year, double-blind, randomized, placebo-controlled trial in postmenopausal women seeking treatment of bothersome vasomotor symptoms. Primary efficacy endpoints were changes in hot flush (HF) frequency and severity on weeks 12, 26, and 52 in an efficacy substudy population (≥50 moderate and severe HFs per week at baseline). Secondary endpoints were Greene climacteric scale, patient global impression symptom rating, and patient global impression of change scores (weeks 12, 26, and 52) for the main study efficacy population. Safety was assessed throughout the trial. The mean baseline HF frequency (efficacy substudy population, n = 365) was 12 moderate and severe HFs per day; the mean baseline severity score was 2.4. At 1 year, women treated with desvenlafaxine maintained the efficacy established on week 12. Desvenlafaxine reduced HF frequency by 7.47 moderate and severe HFs per day on week 12 (adjusted mean difference from placebo, -2.48; 95% CI, -3.47 to -1.50; P Desvenlafaxine reduced the mean severity score by 0.63 on week 12 (placebo, -0.30; P desvenlafaxine than for placebo on months 3, 6, and 12 (all P desvenlafaxine and 79% for placebo (P = 0.006).

    Background: The ideal maxillary injection should produce a rapid onset of profound pulpal anesthesia for multiple teeth from a single needle penetration. The main objective is to compare the efficacy of articaine 4% and lidocaine 2% and to compare anterior middle superior alveolar nerve block (AMSANB) and infraorbital nerve block (IONB) for anesthesia of maxillary teeth. Materials and Methods: Forty patients undergoing root canal treatment of maxillary anteriors and premolars were included and randomly divided into four groups of ten each. Group I: patients receiving AMSANB with articaine, Group II: Patients receiving IONB with articaine, Group III: Patients receiving AMSANB with lidocaine, Group IV: Patients receiving IONB with lidocaine. The scores of onset of anesthesia and pain perception were statistically analyzed. Results: Onset of action was fastest for articaine with AMSANB and slowest for lidocaine with IONB by Tukey's test. A significant change was observed in the electrical pulp test readings at onset and at 30 min by paired t-test. All patients experienced mild pain during the procedure recorded by visual analog scale. Conclusion: Articaine 4% proved to be more efficacious than lidocaine 2%, and AMSANB was more advantageous than IONB in securing anesthesia of maxillary anteriors and premolars. PMID:27994313

    Full Text Available Yadong Li, Jinsong Zhang, Kai Yang Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, People's Republic of China Background: Conventional radical neck dissection often causes a variety of complications. Although the dissection method has been improved by retaining some tissues to reduce complications, the incomplete dissection may cause recurrence of disease. In the present study, we developed a novel radical neck dissection, which preserves the external jugular vein, the greater auricular nerve, and the deep branches of the cervical nerve, to effectively reduce complications and subsequently, to promote the postoperative survival quality. Methods: A total of 100 cases of radical neck dissection were retrospectively analyzed to evaluate the efficacy, rate of complication, and postoperative dysfunction of patients treated with the novel radical neck dissection. Data analysis was performed using the Chi-square test. Results: Compared with conventional radical neck dissection, the novel radical neck dissection could significantly reduce complications and promote postoperative survival quality. Particularly, the preservation of the external jugular vein reduced the surgical risk (ie, intracranial hypertension and complications (eg, facial edema, dizziness, headache. Preservation of the deep branches of the cervical nerve and greater auricular nerve resulted in relatively ideal postoperative functions of the shoulders and ear skin sensory function (P 0.05. Conclusion: Our novel radical neck dissection procedure could effectively reduce the complications of intracranial hypertension, shoulder dysfunction, and ear sensory disturbances. It can be used as a regular surgical approach for oral carcinoma radical neck dissection.

    Forty-three patients who had signs and symptoms possibly related to the extracranial course of cranial nerves V, VII, IX, X-XII, and the cervical sympathetics were examined prospectively using high resolution CT to obtain images of thin sections during rapid drip infusion of contrast material. Anatomic areas in the scan protocols included the posterior fossa, cavernous and paranasal sinuses, skull base, temporal bone, nasopharynx, parotid gland, tongue base, and neck. Nine of the 23 patients with possible fifth nerve deficits had extracranial structural lesions that explained the symptoms; none of these nine, however, had typical trigeminal neuralgia. Of eight patients with peripheral seventh nerve abnormalities, two had positive findings on scans. Of five patients presenting with referred ear pain, three had carcinoma of the upper aerodigestive tract. The authors' experience suggests that patients at high risk for structural lesions responsible for cranial nerve deficits can be selected by clinical criteria. Protocols for each clinical setting are presented.

    Vagus nerve stimulation has recently been reported to improve symptoms of migraine. Cortical spreading depression is the electrophysiological event underlying migraine aura and is a trigger for headache. We tested whether vagus nerve stimulation inhibits cortical spreading depression to explain its antimigraine effect. Unilateral vagus nerve stimulation was delivered either noninvasively through the skin or directly by electrodes placed around the nerve. Systemic physiology was monitored throughout the study. Both noninvasive transcutaneous and invasive direct vagus nerve stimulations significantly suppressed spreading depression susceptibility in the occipital cortex in rats. The electrical stimulation threshold to evoke a spreading depression was elevated by more than 2-fold, the frequency of spreading depressions during continuous topical 1 M KCl was reduced by ∼40%, and propagation speed of spreading depression was reduced by ∼15%. This effect developed within 30 minutes after vagus nerve stimulation and persisted for more than 3 hours. Noninvasive transcutaneous vagus nerve stimulation was as efficacious as direct invasive vagus nerve stimulation, and the efficacy did not differ between the ipsilateral and contralateral hemispheres. Our findings provide a potential mechanism by which vagus nerve stimulation may be efficacious in migraine and suggest that susceptibility to spreading depression is a suitable platform to optimize its efficacy.

    Full Text Available ABSTRACT Objective A large number of psychosocial interventions in dementia are based on music activities and music therapy interventions. We aim at assessing the efficacy of music therapy in the neuropsychiatric symptoms of people with dementia. Methods This systematic review is according to the methodology suggested by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched for articles in PubMed, Web of Knowledge Cross Search, Cochrane Library, Scopus and Lilacs/Bireme databases published from 2005 to 2016. The search keywords included “early onset” and “late onset” combined with “dementia”, “Alzheimer”, “vascular dementia”, “mixed dementia”, “frontotemporal dementia”, “neuropsychiatric symptoms”, “behavioral disturbances”, “behavioral and psychological symptoms of dementia” and “music therapy”. The studies were categorized according to its efficacy on the decline of neuropsychiatric symptoms and improvement of cognitive function, quality of life and well-being. Results We selected 12 out of 257 papers. Music therapy interventions were applied individually or in group setting, using active or receptive technique. In general, studies indicated the efficacy of music therapy on the decline of depression, agitation and anxiety. There were heterogeneity of interventions, methodological design and instruments of evaluation among the studies. Conclusions Although there are reports of the efficacy of music therapy on the decline of neuropsychiatric symptoms of dementia, the area still needs randomized studies aimed at the solution of important methodological problems like the lack of standardized approaches.

    To determine the efficacy of three doses of a new, oral formulation of estradiol acetate (EA) for alleviation of vasomotor and urogenital symptoms in postmenopausal women. Two separate 12-week studies were undertaken in postmenopausal women with moderate to severe vasomotor symptoms. In the first study, women were randomly assigned to EA 0.9 mg/day, EA 1.8 mg/day, or placebo (study 1; N = 293), and in the second study to oral EA 0.45 mg/day or placebo (study 2; N = 259). Women recorded the frequency and severity of vasomotor symptoms daily and urogenital symptoms weekly on diary cards. Investigators assessed signs of vaginal atrophy. Frequency of moderate to severe vasomotor symptoms decreased significantly versus placebo, starting at week 2 in the EA 1.8-mg group (P = 0.005), week 3 in the EA 0.9-mg group (P = 0.003), and week 6 in the EA 0.45-mg group (P < 0.05). At week 12, mean percent reduction from baseline in vasomotor-symptom frequency was 91%, 78%, and 61%, respectively. Vasomotor-symptom severity decreased significantly versus placebo, starting at weeks 2 and 3 with EA 1.8 mg and 0.9 mg, respectively, and at week 5 with EA 0.45 mg. Vaginal pH and maturation index improved significantly in all EA groups versus placebo, and some signs and symptoms of vaginal atrophy improved at the EA 0.9- and 1.8-mg doses. Side effects were mild to moderate and consistent with estrogen therapy. Oral EA at all doses was well tolerated and significantly reduced the frequency and severity of postmenopause symptoms versus placebo.

    Over the course of adolescence, an increasing number of adolescents experience depression. In order to effectively target depression, identifying risk factors for depressive symptoms is pivotal. Since low levels of self-efficacy were associated with higher levels of depressive symptoms in previous studies, the current study investigated the bidirectional and prospective associations between depressive symptoms and academic, social and emotional self-efficacy from early to mid adolescence in a cross-lagged path model. The sample consisted of 1,341 adolescents (47 % girls) with a mean age of 14 years, SD = 0.56. Depressive symptoms and self-efficacy levels were assessed every 6 months over a period of 2.5 years. Depressive symptoms predicted subsequent levels of academic and emotional self-efficacy on all time points, and social self-efficacy on one time point. Self-efficacy did not predict subsequent levels of depressive symptoms. There was no evidence of sex differences in the cross-lagged associations between depressive symptoms and self-efficacy levels. Implications of the findings are discussed.

    Objectives: To compare the efficacy and complication rates of two different techniques for inferior alveolar nerve blocks (IANB). Study Design: A randomized, triple-blind clinical trial comprising 109 patients who required lower third molar removal was performed. In the control group, all patients received an IANB using the conventional Halsted technique, whereas in the experimental group, a modified technique using a more inferior injection point was performed. Results: A total of 100 patients were randomized. The modified technique group showed a significantly higher onset time in the lower lip and chin area, and was frequently associated to a lingual electric discharge sensation. Three failures were recorded, 2 of them in the experimental group. No relevant local or systemic complications were registered. Conclusions: Both IANB techniques used in this trial are suitable for lower third molar removal. However, performing an inferior alveolar nerve block in a more inferior position (modified technique) extends the onset time, does not seem to reduce the risk of intravascular injections and might increase the risk of lingual nerve injuries. Key words:Dental anesthesia, inferior alveolar nerve block, lidocaine, third molar, intravascular injection. PMID:24608204

    Pain in all three divisions of the trigeminal nerve is in over 65% of all cases the first symptom of a tumour in Meckel's cave. Tumors in this location make up only 0,5% of all intracranial tumours. The most common are trigeminal schwannomas and meningeomas. A metastases as a cause of trigeminal pain is a rare description in the literature so far. We describe a patient with trigeminal pain and a tumour in Meckels's cave shown in the MRI, who were operated in our department. The histological examination of the tumour resulted in the diagnosis of metastatic carcinoma of an until then unknown oesophaguscarcinoma. - Although metastatic tumours are rare, we could show with our case, that they have to be included in differential dignostic considerations.

    The aim of this study was to assess the effects of Glial growth factor (GGF) and nerve growth factor (NGF) on nerve regeneration in facial nerve anastomosis. In this study, approximately a 1-mm segment was resected from the facial nerve and the free ends were anastomosed. All animals underwent the same surgical procedure and 30 rabbits were grouped randomly in three groups. Control group, the group without any medications; NGF group, the group receiving 250 ng/0.1 ml NGF in the epineurium at the site of anastomosis; GBF group, the group receiving 500 ng/0.1 ml GGF in the epineurium at the site of anastomosis. Medications were given at the time of surgery, and at 24 and 48 h postoperatively. After 2 months, the sites of anastomosis were excised and examined using the electron microscope. It was found that the best regeneration was in the group receiving GGF as compared to the control group in terms of nerve regeneration. Schwann cell and glial cell proliferation were found to be significantly higher in the group receiving GGF as compared to the group receiving NGF. Besides, the number of myelin debris, an indicator of degeneration, was significantly lower in the group with GGF as compared to NGF and control groups (p NGF in order to increase regeneration after nerve anastomosis in experimental traumatic facial nerve paralysis may be a hopeful alternative treatment option in the future. However, further studies on human studies are required to support these results.

    The purpose of this prospective, non-randomised, descriptive study is to characterise the neurosensory deficit and associated neurogenic discomfort in 52 patients with iatrogenic injury to the inferior alveolar nerve (IAN). All patients were examined and followed up according to a protocol assessing tactile, thermal, and positional perception as well as two-point discrimination and pain. In 48 patients with IAN injuries of differing etiologies who did not undergo surgery, 32 patients with injury associated with third molar surgery exhibited significant spontaneous improvement of sensory function. Recovery improvement of sensory function was insignificant in the patients with other etiologies. In most patients the level of sensory perception was such that microsurgical repair was only occasionally indicated. Four patients had microsurgical repair; the outcome was favourable in three. IAN injuries associated with third molar surgery, other dento-alveolar surgery or implant surgery occur sufficiently often to render prevention a key issue.

    To assess the efficacy, tolerability, and acceptance of a vaginal ring delivering the equivalent of 50 or 100 microg per day of estradiol (E2), compared with placebo, for relief of moderate to severe vasomotor symptoms and urogenital symptoms in postmenopausal women. Women with moderate to severe vasomotor symptoms (seven or more per day or 56 per week average) received 13 weeks of treatment with a vaginal ring delivering 50 microg per day E2 (n = 113) or 100 microg per day E2 (n = 112), or a placebo vaginal ring (n = 108). Severity of vasomotor symptoms was assessed by a daily diary card and the Greene Climacteric Scale. Urogenital signs and symptoms were evaluated via patient and physician assessment and vaginal cytology. Participant satisfaction with the vaginal ring was evaluated via questionnaire. Vasomotor symptoms significantly improved in both treatment groups, compared with placebo (P <.05). There was a trend toward greater improvement in patient assessment of urogenital signs with active rings compared with placebo. For women with vaginal atrophy at baseline (n = 60), the maturation index improved significantly in both treatment groups compared with placebo. Total Greene Climacteric Scale scores significantly improved for both E2 vaginal ring groups (P <.05) compared with placebo. The vaginal rings were well tolerated. Most adverse events were mild or moderate and consistent with estrogen therapy. A novel vaginal ring delivering the equivalent of 50 or 100 microg per day of E2 significantly reduced the number and severity of vasomotor symptoms and improved urogenital symptoms, compared with placebo. The E2 vaginal ring was well tolerated.

    Despite being one of the first-choice analgesics for chronic neuropathic pain, gabapentin sometimes fails to provide analgesia, but the mechanisms for this lack of efficacy is unclear. Rats with nerve injury including L5-L6 spinal nerve ligation (SNL) respond uniformly and well to gabapentin, but many of these studies are performed within just a few weeks of injury, questioning their relevance to chronic neuropathic pain. In this study, intraperitoneal gabapentin showed a time-dependently reduction in antihypersensitivity after SNL, associated with downregulation of astroglial glutamate transporter-1 (GLT-1) in the locus coeruleus (LC). Consistently, SNL also time-dependently increased basal but masked gabapentin-induced noradrenergic neuronal activity in the LC. In rats 2 weeks after SNL, knock-down of GLT-1 in the LC reduced the antihypersensitivity effect of gabapentin. In rats 8 weeks after SNL, increasing GLT-1 expression by histone deacetylase inhibitor valproate restored the antihypersensitivity effect of gabapentin, associated with restored gabapentin-induced noradrenergic neuronal activity in the LC and subsequent spinal noradrenaline release. Knock-down of GLT-1 in the LC reversed the effect of valproate to restore gabapentin-induced antihypersensitivity. In addition, the antihypersensitivity effect of the intrathecal α2-adrenoceptor agonist clonidine also decreased with time after SNL injury. These results suggest that downregulation of GLT-1 in the LC and reduced spinal noradrenergic inhibition contribute to impaired analgesic efficacy from gabapentin in chronic neuropathic pain and that valproate can rescue this impaired efficacy.

    Several studies have described the evidence of prenatal physiotherapy for one symptom, but none has made an overview. We provided a systematic review on the effectiveness of prenatal physiotherapy. A full search was conducted in three electronic databases (Embase, PubMed/MEDLINE and PEDro), selecting randomized controlled trials concerning prenatal physiotherapy. Methodological quality was assessed using the PEDro scale. We identified 1,249 studies and after exclusions 54 studies were included concerning the evidence of prenatal physiotherapy. The majority of studies indicated a preventative effect for low back pain/pelvic girdle pain, weight gain, incontinence, and perineal massage. For leg edema, fear, and prenatal depression, the efficacy was only based on one study per symptom. No preventative effect was found for gestational diabetes, while literature concerning gestational hypertensive disorders was inconclusive. Regarding the treatment of low back pain/pelvic girdle pain and weight gain, most therapies reduced pain and weight respectively. Evidence regarding exercises for diabetes was contradictory and only minimally researched for incontinence. Foot massage and stockings reduced leg edema and leg symptoms respectively. Concerning gestational hypertensive disorders, perineal pain, fear, and prenatal depression no treatment studies were performed. The majority of studies indicated that prenatal physiotherapy played a preventative role for low back pain/pelvic girdle pain, weight gain, incontinence, and pelvic pain. Evidence for the remaining symptoms was inclusive or only minimally investigated. Regarding treatment, most studies indicated a reduction of low back pain/pelvic girdle pain, weight gain, incontinence, and the symptoms of leg edema.

  4. College Adjustment as a Mediator Between Attention Deficit/Hyperactivity Disorder Symptoms and Work Self-Efficacy

    Clarissa Tochetto de Oliveira

    Full Text Available Abstract Studies have addressed features of Attention Deficit/Hyperactivity Disorder (ADHD in higher education, but the potential relationships between ADHD symptoms, dimensions of college adjustment and students' work self-efficacy remain scarcely explored. The aim of this study was to test a theoretical model in which the dimensions of college adjustment mediate the relationship between ADHD symptoms and work self-efficacy. Participants were 509 college students from two Brazilian public universities. Data were collected using questionnaires and analyzed using a path analysis model. The ADHD symptoms affected work self-efficacy exclusively through college adjustment problems. Improving students' well-being, social support networks, study habits, and feelings regarding their majors and the university may reduce the potential disadvantages in work self-efficacy caused by ADHD symptoms.

    Full Text Available The purpose of this study was to investigate the direct and indirect relationship between unemployment and anxiety symptoms, through job search-self efficacy (JSSE. A total of 30 participants who lost their jobs from the same employing organization were used in this two wave longitudinal study. Participants filled out two questionnaires comprising the Trimodal Anxiety Questionnaire and a Job Search Self-Efficacy subscale at the beginning of the study (T1 and after three months (T2. Results show that participants who were still unemployed three months after being laid off reported higher symptoms of anxiety compared to those who had been reemployed (ηp2 = .13. We also found that participants who were reemployed reported higher levels of JSSE at T2 compared to those who were still unemployed (ηp2 = .25. Moreover, there was a significant negative association between JSSE and anxiety at T1 and at T2. Furthermore, the analysis conducted shows evidence for the mediating role of JSSE in the relationship between employment status and anxiety symptoms. The applied potential of these findings is discussed.

    Full Text Available Two patients presented from outside hospitals with complaints of pain at the site of implantable pulse generator (IPG. Neither patient had constitutional or local signs and symptoms of infection; however, during operations performed for revision and/or troubleshooting of the device, infection was encountered and all components were removed. Both individuals recovered well from the operation, and one patient underwent subsequent placement of a new InterStim device with good results. Possibility of infection should be considered in patients with complaint of pain associated with IPG site.

    Previous research indicates self-efficacy may function as a protective factor for survivors of partner violence (PV), including coping self-efficacy specific to domestic violence. We hypothesized that domestic violence coping self-efficacy would moderate the association between recent PV and posttraumatic stress disorder (PTSD) symptoms in a sample of incarcerated women, such that the association between PV and PTSD would be strongest at low levels of domestic violence coping self-efficacy. Participants (N = 102) were incarcerated women who reported PV in the year prior to incarceration. They were aged 19-55 years (M = 33.57, SD = 9.32), identified predominantly as European American (84.3%), American Indian (15.7%), and Hispanic (14.7%), with 80.4% completing high school or more in terms of education. Participants responded to self-report measures of PV, trauma history, domestic violence coping self-efficacy, and current PTSD symptoms. In a series of sequential regression analyses, PV (β = .65, sr(2) = .06, p = .017) was significantly associated with current PTSD symptoms above and beyond past trauma history (β = .37, sr(2) = .14, p self-efficacy (Domestic Violence Coping Self-Efficacy × Partner Violence; β = -.54, sr(2) = .03, p = .044). The relationship between PV and PTSD symptoms was greatest at low and average levels of domestic violence coping self-efficacy and nonsignificant at high levels of domestic violence coping self-efficacy. These findings highlight the importance of assessing domestic violence coping self-efficacy in incarcerated women with recent PV, given that domestic violence coping self-efficacy appeared to be protective against symptoms of PTSD.

    To compare the efficacy and complication rates of two different techniques for inferior alveolar nerve blocks (IANB). A randomized, triple-blind clinical trial comprising 109 patients who required lower third molar removal was performed. In the control group, all patients received an IANB using the conventional Halsted technique, whereas in the experimental group, a modified technique using a more inferior injection point was performed. A total of 100 patients were randomized. The modified technique group showed a significantly higher onset time in the lower lip and chin area, and was frequently associated to a lingual electric discharge sensation. Three failures were recorded, 2 of them in the experimental group. No relevant local or systemic complications were registered. Both IANB techniques used in this trial are suitable for lower third molar removal. However, performing an inferior alveolar nerve block in a more inferior position (modified technique) extends the onset time, does not seem to reduce the risk of intravascular injections and might increase the risk of lingual nerve injuries.

    Anxiety symptoms are prevalent in patients with major depressive disorder. A post-hoc analysis of two phase III trials was conducted to evaluate the efficacy of vilazodone on depression-related anxiety. Using the 17-item Hamilton Depression Rating Scale (HAMD17) Anxiety/Somatization subscale, patients were classified as anxious or nonanxious. Improvements in depressive symptoms were based on least squares mean changes in HAMD17 and Montgomery-Asberg Depression Rating Scale total scores. Anxiety symptoms in the anxious subgroup were evaluated using Hamilton Anxiety Rating Scale (HAMA) total and subscale (Psychic Anxiety, Somatic Anxiety) scores, HAMD17 Anxiety/Somatization subscale and item (Psychic Anxiety, Somatic Anxiety) scores, and the Montgomery-Asberg Depression Rating Scale Inner Tension item score. Most of the pooled study population [82.0% (708/863)] was classified with anxious depression. After 8 weeks of treatment, least squares mean differences between vilazodone and placebo for changes in HAMA total and HAMD17 Anxiety/Somatization subscale scores were -1.82 (95% confidence interval -2.81 to -0.83; Pmajor depressive disorder who exhibit somatic and/or psychic symptoms of anxiety.

    Among the gramineae species, orchard grass is a typical causative pollen that provokes seasonal rhinitis. The purpose of this study was to examine the protective efficacy of epinastine hydrochloride for signs and symptoms caused by repeated nasal provocation with discs containing orchard grass pollen. A single-dose, placebo-controlled, double-blind, crossover clinical study was conducted in subjects with orchard grass pollinosis. The pollen challenge was conducted with the use of provocation discs containing orchard grass pollen. Epinastine hydrochloride suppressed nasal symptoms caused by nasal provocation tests using orchard grass pollen discs. Among the nasal symptoms, the number of sneezing was significantly inhibited 30 minutes and 60 minutes after the administration of epinastine hydrochloride, as compared with placebo. There were no adverse reactions to the study drugs. Our results suggest that nasal provocation tests with discs containing orchard grass pollen is a useful method for evaluating the onset of action of antiallergic drugs. As compared with placebo, epinastine hydrochloride decreased early-phase sneezing and the total nasal symptom score after repeated nasal provocations with orchard grass pollen discs.

    Full Text Available Abstract Background The most severe complication after the removal of mandibular third molars is injury to the inferior alveolar nerve or the lingual nerve. These complications are rather uncommon (0.4% to 8.4% and most of them are transient. However, some of them persist for longer than 6 months, which can leave various degrees of long-term permanent disability. While several methods such as pharmacologic therapy, microneurosurgery, autogenous and alloplastic grafting can be used for the treatment of long-standing sensory aberrations in the inferior alveolar nerve, there are few reports regarding low level laser treatment. This paper reports the effects of low level laser therapy in 4 patients with longstanding sensory nerve impairment following mandibular third molar surgery. Methods Four female patients had complaints of paresthesia and dysesthesia of the lip, chin and gingiva, and buccal regions. Each patient had undergone mandibular third molar surgery at least 1 year before. All patients were treated with low level laser therapy. Clinical neurosensory tests (the brush stroke directional discrimination test, 2-point discrimination test, and a subjective assessment of neurosensory function using a visual analog scale were used before and after treatment, and the responses were plotted over time. Results When the neurosensory assessment scores after treatment with LLL therapy were compared with the baseline values prior to treatment, there was a significant acceleration in the time course, as well as in the magnitude, of neurosensory return. The VAS analysis revealed progressive improvement over time. Conclusion Low level laser therapy seemed to be conducive to the reduction of long-standing sensory nerve impairment following third molar surgery. Further studies are worthwhile regarding the clinical application of this treatment modality.

    High levels of depressive and anxiety symptoms have been reported by individuals with multiple sclerosis (MS). This study examined the associations between resilience, self-efficacy and coping and depressive and anxiety symptoms and whether resilience, self-efficacy and coping were predictors of depressive and anxiety symptoms in patients newly diagnosed with MS. A sample of 129 individuals newly diagnosed with MS participated in this cross-sectional study and completed an online questionnaire assessing resilience, self-efficacy, coping and depressive and anxiety symptoms. Results revealed that depressive and anxiety symptoms were significantly associated with problem-focused, emotion-focused and avoidance coping strategies, resilience and self-efficacy. Anxiety symptoms were also significantly associated with employment status and level of disability. Results from hierarchical multiple regression revealed that the resilience subscale of personal competence, the avoidance coping style of substance use and emotion-focused coping styles of venting predicted depressive symptoms and uniquely accounted for 63.8% of the variance in the depression score, F (18, 124) = 10.36, p = .000. Level of disability and employment status accounted for 13.2% of the anxiety score and avoidance coping style of denial and emotion-focused coping style of humour accounted for 36.4% of the variance in the anxiety symptom score, F (15, 112) = 6.37, p = .000. Our findings suggest that resilience and avoidance and emotion-focused coping strategies are predictive of depressive symptoms and anxiety symptoms in those newly diagnosed with MS. Resilience and coping styles may be another target for interventions aimed at managing depressive and anxiety symptoms in those newly diagnosed with MS.

    OBJECTIVE:China is the only country where nerve growth factor is approved for large-scale use as a clinical medicine. More than 10 years ago, in 2003, nerve growth factor injection was listed as a national drug. The goal of this article is to evaluate comprehensively the efifcacy and safety of nerve growth factor for the treatment of neurological diseases. DATA RETRIEVAL:A computer-based retrieval was performed from six databases, including the Cochrane Library, PubMed, EMBASE, Sino Med, CNKI, and the VIP database, searching from the clinical establishment of nerve growth factor for treatment until December 31, 2013. The key words for the searches were “nerve growth factor, randomized controlled trials” in Chinese and in English. DATA SELECTION:Inclusion criteria: any study published in English or Chinese referring to randomized controlled trials of nerve growth factor; patients with neurological diseases such as peripheral nerve injury, central nerve injury, cranial neuropathy, and nervous system infections;patients older than 7 years; similar research methods and outcomes assessing symptoms; and measurement of nerve conduction velocities. The meta-analysis was conducted using Review Manager 5.2.3 software. MAIN OUTCOME MEASURES:The total effective rate, the incidence of adverse effects, and the nerve conduction velocity were recorded for each study. RESULTS:Sixty-four studies involving 6,297 patients with neurological diseases were included. The total effective rate in the group treated with nerve growth factor was significantly higher than that in the control group (P < 0.0001,RR: 1.35, 95%CI: 1.30–1.40). The average nerve conduction velocity in the nerve growth factor group was signiifcantly higher than that in the control group (P < 0.00001,MD: 4.59 m/s, 95%CI: 4.12–5.06). The incidence of pain or sclero-ma at the injection site in the nerve growth factor group was also higher than that in the control group (P < 0.00001,RR: 6.30, 95%CI: 3.53–11

    2008-01-01

    To compare efficacy and safety of desvenlafaxine succinate (desvenlafaxine) with placebo for the treatment of vasomotor symptoms. This randomized, double-blind, placebo-controlled trial enrolled 707 healthy, postmenopausal women experiencing 50 or more moderate-to-severe hot flushes per week. Participants randomly received desvenlafaxine 50, 100, 150, or 200 mg or placebo daily. Trial duration was 52 weeks. Primary outcomes were change from baseline in average daily number of moderate-to-severe hot flushes and in daily hot flush severity score at weeks 4 and 12. Six hundred twenty women with an average of 11 moderate-to-severe hot flushes per day at baseline completed at least one on-therapy evaluation for primary efficacy end points; 519 participants completed 12 weeks of treatment, and 368 completed the study. Desvenlafaxine 100 mg/d achieved a significantly greater reduction compared with placebo in average daily number of hot flushes at weeks 4 (P=.013) and 12 (P=.005), reaching a 64% decrease from baseline at week 12, and the 75% responder rate was significantly higher for desvenlafaxine 100 mg (50%) compared with placebo (29%; P=.003; number needed to treat=4.7) at week 12. Average daily severity of hot flushes was significantly lower in the desvenlafaxine 100-mg group compared with placebo at week 12 (P=.020). Desvenlafaxine-treated women reported significantly more treatment-emergent adverse events than placebo-treated women during the first week of therapy only. Desvenlafaxine is an effective nonhormonal treatment for vasomotor symptoms in postmenopausal women. Its tolerability profile is consistent with that of other serotonin-norepinephrine reuptake inhibitors. ClinicalTrials.gov, www.clinicaltrials.gov, NCT00421031 I.

  2. Efficacy of Drospirenone-Containing Hormone Replacement Therapy to Reduce Vasomotor Symptoms of Menopause

    2013-10-01

    Full Text Available Hormone replacement therapy has been proven efficacious for controlling vasomotor symptoms such as hot flushes associated with menopause. Drospirenone is a progestin with antiandrogenic and antimineralocorticoid activity that may be used in combination with estrogen to control hot flushes and offers the potential benefit of minimizing breast tenderness, blood pressure elevations and weight gain. Six clinical trials were reviewed. Of these, four trials explicitly listed hot flushes as a primary outcome. Efficacy with regards to hot flushes was found to range from modest to large (i.e., 37.5% to 94.6%, and four of the studies utilized diary cards to assess hot flushes. Results from these studies must be interpreted cautiously as quite a few limitations existed such as small population sizes involving specific ethnic groups, lack of p values with regards to baseline characteristics lending question to homogeneity, and inclusion of mostly healthy participants. Additionally, while the studies were long enough to see an effect, the long term effects of drospirenone-containing hormone replacement therapy (HRT is unknown. The available data supports the use of drospirenone-containing HRT for the treatment of hot flushes associated with menopause.

    According to an epidemiological study in Japan, there are as many as 22 million patients with tension headache and 8.4 million with migraine. Furthermore, patients suffering from both types of headache concurrently are estimated to account for more than 50% of headache patients. We studied the efficacy of drug therapy for migraine accompanied by tension headache-like symptoms, focusing principally on neck stiffness. We evaluated the efficacy of rizatriptan by comparison of findings before and after therapy in 34 migraine patients, consisting of 16 without neck stiffness (migraine without neck factor: WONF) and 18 with it (migraine with neck factor: WNF), who received treatment at our neurology/internal medicine department from 1 March 2004 to 31 May 2005. In the study, all the patients were asked to keep a record of their migraine status. The severity of migraine was classified by physicians according to the International Headache Society diagnostic criteria, based on which drug efficacy was evaluated. We selected rizatriptan for migraine treatment in our study based on Dr. Ferrari's report. In the efficacy study of rizatriptan, in the group of 34 migraine patients, the pain relief rate (79.4%) and pain-free rate (41.2%) at two hours after treatment were as high as those reported in the meta-analysis performed by Ferrari et al., indicating high efficacy of rizatriptan. In the efficacy comparison between the WONF and WNF groups, the painfree rates were 56.3% and 27.8%, and cumulative pain relief rates were 100% and 61.1%, respectively, with better results in the WONF group. A test result was also significantly better (p=0.0076) in the WONF group. Rizatriptan was proved effective in treating migraine patients accompanied by tension headache-like symptoms. Comparison of efficacy rates between patient groups with and without tension headache-like symptoms showed that the pain relief rate in the group without neck stiffness was higher.

    Full Text Available The incidence of PTSD and other combat-related trauma symptoms among more than 2 million veterans returning from Operation Iraqi Freedom (OIF and Operation Enduring Freedom (OEF in Afghanistan suggests that many will experience psychological challenges in adjusting to civilian life. However, the literature is sparse about this new group of veterans. This study examined the relationships between peer support, self-efficacy, and PTSD symptoms among 216 OIF/OEF veterans who had attended 1 of 17 Vets4Vets peer support weekend retreats. Vets4Vets is a national grassroots program whose mission is to improve the psychological well-being of returning OIF/OEF veterans. Analysis of posttest changes indicate the generalizability of previous research findings, based on other groups of trauma-affected groups, to OIF/OEF veterans. As predicted, increased perceived peer support and self-efficacy reduced PTSD symptoms. From a theoretical perspective, we found that both models of self-efficacy, situation-specific (Bandura, 1997; Benight & Bandura, 2004 and general self-efficacy (Schwarzer & Fuchs, 1996, mediated or explained the relationship between peer support and PTSD symptoms. Implications for social work are discussed.

    A traditional Chinese herbal medicine, Kampo medicine, maoto, has been widely used in the treatment of febrile symptoms caused by viral infection. This herbal extract granule for oral use, however, is not well accepted by infants or young children due to its unpleasant taste and odor. Therefore, we prepared Kampo medicine, maoto, suppository and investigated the pharmaceutical and clinical efficacy of the suppository. Kampo medicine, maoto, granules were micro-pulverized and homogeneously dispersed into Hosco-H15 to prepare suppositories containing 0.25 to 1.0 g herbal extract by the conventional fusion method. Content of l-ephedrine, an index compound of Kampo medicine, maoto, in the extract granules and suppositories was determined by using a high performance liquid chromatographic method. Physicochemical experiments revealed that the suppository containing 0.5 g herbal extract had the most suitable melting point of 34 degrees C. Contents of l-ephedrine in the suppository were constant, 93-96% of those in the same amount of the extract granules in different three lots. Upper and lower portions of the suppository had the same content of l-ephedrine. The suppository maintained more than 95% of l-ephedrine content through 6 months at 4 degrees C, room temperature and 40 degrees C, although maldistribution of the extract constituent was observed after storage at 40 degrees C. The suppository was administered to 21 pediatric febrile patients at a dose of 1/3 to 2 full pieces depending on their body weight and physical status. Significant reduction (psuppository was found to satisfy the physicochemical quality and quantity standards as well as to be clinically applicable to neonates, infants and children with viral febrile symptoms without any adverse effects.

    Nerve growth factor (NGF) is associated with arthritic pain and metalloproteinases are implicated in collagen and aggrecan degradation. Although selective COX-2 inhibitors are recommended for the treatment of arthritic diseases, their effects on NGF and metalloproteinases remain unclear. This study investigated the regulations of NGF and metalloproteinases by selective COX-2 inhibitors in isolated human synovial cells. The isolated human synovial cells were stimulated with IL-1β in the presence of selective COX-2 inhibitors (NS-398 or celecoxib) with or without exogenous PGE2 or its receptor (EP1-4) agonists. The expressions of NGF, MMP-1, -3, -13, ADAMTS-4, and -5 were quantified by real-time PCR and their proteins were determined by Western blotting. The amount of PGE2 released was measured by enzyme-linked immunosorbent assay (ELISA). The IL-1β inductions of NGF and MMP-1 and MMP-13 were augmented by the COX-2 inhibitors, whereas the inductions of ADAMTS-4 and ADAMTS-5 were inhibited. These actions were reversed by supplementing PGE2 or the EP4 agonist exogenously. Our comprehensive analysis revealed that COX-2 inhibitors may be beneficial for suppressing aggrecan degradation and for reducing inflammatory pain by inhibiting PGE2 release, although they may have limited efficacy in suppressing collagen degradation and nerve growth. This study suggests the feedback roles of PGE2 in the negative regulation of NGF and MMP-1 and MMP-13 and the positive regulation of ADAMTS-4 and ADAMTS-5.

    The aim of this study was to assess the long-term safety, tolerability and efficacy of fesoterodine treatment in subjects with overactive bladder (OAB) symptoms. This was an open-label extension study of a 12-week, double-blind fesoterodine study. During open-label treatment, all subjects received fesoterodine 8 mg for an initial 4 weeks, after which subjects could elect dose reduction to 4 mg or subsequent reescalation to 8 mg during clinic visits (dose reduction and reescalation each permitted once annually). The maximum allowable duration of open-label fesoterodine treatment ranged from 24 to 32 months across study sites. Safety and tolerability were evaluated via discontinuations, fesoterodine exposure, treatment-emergent adverse events (TEAEs) and subject-reported treatment tolerance. Three-day bladder diaries and other patient-reported outcomes (PROs) were assessed during the first 24 months of open-label treatment. PROs included evaluations of health-related quality of life [HRQL; King's Health Questionnaire (KHQ), and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF)], severity of bladder-related problems and treatment satisfaction. Subjects completed 3-day diaries before open-label baseline and months 1, 4, 8, 12 and 24; the ICIQ-SF and measures of bladder-related problems and treatment satisfaction at open-label baseline and months 4, 12 and 24; and the KHQ at open-label baseline and months 12 and 24. Of the 417 eligible subjects who enrolled in the open-label extension, 61% continued fesoterodine treatment for > or = 24 months and 71% elected to maintain the fesoterodine 8-mg dose throughout treatment. No unexpected safety signals were observed. Most subjects rated treatment tolerance as at least 'good' throughout the study (> or = 88%). Dry mouth was the most commonly reported TEAE (34%) during open-label treatment, resulting in discontinuation in 2% of subjects (n = 8). Improvements from open-label baseline in OAB symptoms

    The effectiveness of nonsteroidal antiinflammatory drugs (NSAIDs) for the management of pain in osteoarthritis and other musculoskeletal diseases is well documented. The role of NSAIDs is less clear in the treatment of conditions involving soft tissue inflammation, including the airways, ear-nose-throat (ENT) system and urogenital tract. These conditions are often treated inappropriately with antibiotics. Morniflumate, the ß-morpholinoethyl ester of niflumic acid, is a member of the fenamate family of NSAIDs indicated for the treatment of inflammatory conditions (with or without pain) affecting airways, the ENT system, urogenital tract and the osteoarticular system. Morniflumate has a 30-year history of clinical use, particularly for the treatment of pain associated with paediatric ENT infection. This article reviews evidence supporting the efficacy and safety of morniflumate. Based on available evidence and the favourable tolerability profile emerging from extensive clinical use, morniflumate appears to be a valid and well-tolerated alternative to other NSAIDs, or to antibiotics, for the treatment of pain and other symptoms of soft tissue inflammation.

    Millions of volunteers respond after disasters, with a 24% to 46% risk of developing posttraumatic stress disorder (PTSD). It is unclear which symptom trajectories develop and how they differ between core (volunteering before the disaster) and noncore volunteers (joining after the disaster) and which factors predict trajectories. Symptoms of PTSD were assessed at 6-, 12-, and 18-months postearthquake in 449 volunteers in Indonesia. Demographics, previous mental health service use, self-efficacy, social acknowledgment, and type of tasks were assessed at 6 months. In both core and noncore volunteers, 2 PTSD symptom trajectories emerged: a resilient trajectory (moderate levels of symptoms with a slow decrease over time; 90.9%) and a chronic trajectory (higher levels of symptoms with an increase over time; 9.1%). In both trajectories, core volunteers had fewer symptoms than noncore volunteers. Core volunteers in the chronic trajectory were characterized by having sought prior mental help, reported lower levels of self-efficacy and social acknowledgment, and were more likely to have provided psychosocial support to beneficiaries (Cramér's V = .17 to .27, partial η(2) = .02 to .06). Aid organizations should identify and follow up chronic PTSD trajectories in volunteers, including the noncore, who may be out of sight to the organization after the acute response phase.

    Trauma-related coping self-efficacy (CSE), the perceived capability to manage one's personal functioning and the myriad environmental demands of the aftermath of potentially traumatic events (PTE), has been shown to affect psychological outcomes after these events. Aim of the present four-wave study was to examine the cross-lagged relationships between CSE and posttraumatic stress disorder (PTSD) symptoms following PTEs in order to examine direction of influence. Levels of CSE and PTSD symptoms were measured with 4-month intervals. In addition, prospectively assessed personality traits and general self-efficacy perceptions as well as peritraumatic distress were entered in the analyses. The study sample consists of adult respondents of a representative internet panel who experienced PTE in the six months before T1, and did not experience any new PTE or life event between T1 and T3 (N = 400). Respondents were administered the coping self-efficacy scale (CSE-7), impact of event scale (IES) and arousal items of IES-R at each wave (T1 through T3), as well as questions on peritraumatic stress and prospectively measured personality traits (T0). Results of structural equation modeling showed that the effect of CSE on subsequent PTSD symptom levels was dominant. CSE significantly predicted subsequent symptoms, over and above earlier symptom levels, with higher CSE associated with lower PTSD. Symptoms in turn, did not predict subsequent levels of CSE. Higher peritraumatic distress was associated with both higher initial PTSD symptoms and lower initial CSE levels. Higher levels of the personality traits of emotional stability and agreeableness were associated with higher initial CSE levels. This supports a model in which CSE perceptions play an important role in recovery from trauma.

    OBJECTIVE Vagal nerve stimulation (VNS) and corpus callosotomy (CC) have both been shown to be of benefit in the treatment of medically refractory epilepsy. Recent case series have reviewed the efficacy of VNS in patients who have undergone CC, with encouraging results. There are few data, however, on the use of CC following VNS therapy. METHODS The records of all patients at the authors' center who underwent CC following VNS between 1998 and 2015 were reviewed. Patient baseline characteristics, operative details, and postoperative outcomes were analyzed. RESULTS Ten patients met inclusion criteria. The median follow-up was 72 months, with a minimum follow-up of 12 months (range 12-109 months). The mean time between VNS and CC was 53.7 months. The most common reason for CC was progression of seizures after VNS. Seven patients had anterior CC, and 3 patients returned to the operating room for a completion of the procedure. All patients had a decrease in the rate of falls and drop seizures; 7 patients experienced elimination of drop seizures. Nine patients had an Engel Class III outcome, and 1 patient had a Class IV outcome. There were 3 immediate postoperative complications and 1 delayed complication. One patient developed pneumonia, 1 developed transient mutism, and 1 had persistent weakness in the nondominant foot. One patient presented with a wound infection. CONCLUSIONS The authors demonstrate that CC can help reduce seizures in patients with medically refractory epilepsy following VNS, particularly with respect to drop attacks.

    Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors with low survival rates and the leading cause of death in neurofibromatosis type 1 (NF1) patients under 40 years old. Surgical resection is the standard of care for MPNSTs, but is often incomplete and can generate loss of function, necessitating the development of novel treatment methods for this patient population. Here, we describe a novel combination therapy comprising MEK inhibition and nanoparticle-based photothermal therapy (PTT) for MPNSTs. MEK inhibitors block activity driven by Ras, an oncogene constitutively activated in NF1-associated MPNSTs, while PTT serves as a minimally invasive method to ablate cancer cells. Our rationale for combining these seemingly disparate techniques for MPNSTs is based on several reports demonstrating the efficacy of systemic chemotherapy with local PTT. We combine the MEK inhibitor, PD-0325901 (PD901), with Prussian blue nanoparticles (PBNPs) as PTT agents, to block MEK activity and simultaneously ablate MPNSTs. Our data demonstrate the synergistic effect of combining PD901 with PBNP-based PTT, which converge through the Ras pathway to generate apoptosis, necrosis, and decreased proliferation, thereby mitigating tumor growth and increasing survival of MPNST-bearing animals. Our results suggest the potential of this novel local-systemic combination “nanochemotherapy” for treating patients with MPNSTs.

Materials and Methods: This clinical trial was conducted on thirty new cases of gastric cancer patients whose treatment protocol was planned on chemotherapy and were allocated into two groups by simple random sampling. Intervention group (15 patients received olanzapine tablets (2.5–10 mg/day a day before the beginning of chemotherapy; in the 1st day of chemotherapy to 8 weeks after chemotherapy, besides the routine treatment regimens. The control group received only the routine treatment regimens. The patients were followed for 8 weeks after intervention. All of the patients were assessed with Hospital Anxiety and Depression Scale (HADS and WHO-QOL-BREF questionnaires; further, Rhodes index was used to evaluate nausea and vomiting (N/V status. Results: All the recruited patients continued the allocated interventions (no lost to follow-up. N/V decreased in the case group, but the difference was not statistically significant (P = 0.438. The patients' appetite and body mass index increased (P = 0.006. Anxiety and depression subscales of HADS had significant differences between the two groups (P 0.05. No significant increase was observed in fasting and 2-h postprandial blood glucose and lipid profile (P > 0.05. Conclusion: Olanzapine can be considered as an effective drug to increase appetite and decrease anxiety and depression in patients with gastric cancer.

    AbstractBackgroundPeripheral nerve blocks are effective in treating acute pain, thereby minimizing the requirement for opiate analgesics. Fractured neck of femur (FNF) is a common, painful injury. The provision of effective analgesia to this cohort is challenging but an important determinant of their functional outcome. We investigated the analgesic efficacy of continuous femoral nerve block (CFNB) in patients with FNF.MethodsFollowing institutional ethical approval and with informed consent, patients awaiting FNF surgery were randomly allocated to receive either standard opiate-based analgesia (Group 1) or a femoral perineural catheter (Group 2). Patients in Group 1 received parenteral morphine as required. Those in Group 2 received a CFNB comprising a bolus of local anaesthetic followed by a continuous infusion of 0.25% bupivacaine. For both Groups, rescue analgesia consisted of intramuscular morphine as required and all patients received paracetamol regularly. Pain was assessed using a visual analogue scale at rest and during passive movement (dynamic pain score) at 30 min following first analgesic intervention and six hourly thereafter for 72 hours. Patient satisfaction with the analgesic regimen received was recorded using verbal rating scores (0-10). The primary outcome measured was dynamic pain score from initial analgesic intervention to 72 hours later.ResultsOf 27 recruited, 24 patients successfully completed the study protocol and underwent per protocol analysis. The intervals from recruitment to the study until surgery were similar in both groups [31.4(17.7) vs 27.5(14.2) h, P = 0.57]. The groups were similar in terms of baseline clinical characteristics. For patients in Group 2, pain scores at rest were less than those reported by patients in Group 1 [9.5(9.4) vs 31(28), P = 0.031]. Dynamic pain scores reported by patients in Group 2 were less at each time point from 30 min up to 54 hours [e.g at 6 h 30.7(23.4) vs 67.0(32.0), P = 0

    To study the immediate and short-term efficacy of adding transcutaneous electrical nerve stimulation (TENS) to standardized physical therapy on subacute spasticity within 6 months of spinal cord injury. Randomized controlled trial for 3 weeks. A university hospital. Subjects (N=16) with clinically determined spasticity were randomly assigned to either the experimental group (n=8) or the control group (n=8). Sixty-minute sessions of TENS over the bilateral common peroneal nerves before 30 minutes of physical therapy for the experimental group and 30 minutes of physical therapy alone for the control group. All patients in both groups had access to standardized rehabilitation care. The composite spasticity score, which included 3 subscores (ankle jerk, muscle tone, and ankle clonus scores), was used as the primary end point to assess plantar flexor spasticity. These subscores were designated as secondary end points. Serial evaluations were made at baseline before study entry and immediately after the first and last sessions in both groups. On analysis for immediate effects, there was a significant reduction only in the composite spasticity score (mean difference, 1.75; 99% confidence interval [CI], 0.47-3.03; P=.002) in the experimental group, but no significant reduction was observed in all outcome variables in the control group. A significant difference in the composite spasticity score (1.63; 99% CI, 0.14-3.11; P=.006) was observed between the 2 groups. After 15 sessions of treatment, a significant reduction was determined in the composite spasticity score (2.75; 99% CI, 1.31-4.19; P<.001), the muscle tone score (1.75; 99% CI, 0.16-3.34; P=.006), and the ankle clonus score (0.75; 99% CI, 0.18-1.32; P=.003) in the experimental group, whereas none of the outcome variables revealed a significant reduction in the control group. The between-group difference was significant only for the composite spasticity score (2.13; 99% CI, 0.59-3.66; P=.001) and the muscle tone

    Posttraumatic stress disorder (PTSD) is associated with mild neurocognitive deficits, yet clients often complain of cognitive problems that exceed what their objective performance demonstrates. In addition, PTSD is associated with negative appraisals about the self, traumatic event, and one's ability to cope. This study examined posttraumatic cognitions as a moderator, and trauma coping self-efficacy as a mediator, of the relationship between PTSD symptoms and self-report of cognitive problems. A sample of 268 trauma-exposed adults completed the PTSD Checklist for DSM-5, the Posttraumatic Cognitions Inventory, the Trauma Coping Self-Efficacy Scale, the Cognitive Self-Report Questionnaire, and the Quality of Life Scale. Negative self-appraisals was a significant moderator in the relationship between PTSD symptoms and perception of cognitive problems (β = -.252, p = .001). In participants with high levels of negative posttraumatic cognitions, perception of cognitive problems was high regardless of PTSD symptom level. In a mediator analysis, there was a significant indirect effect of trauma coping self-efficacy (b = .125, 95% CI [.088, .172]). Finally, there was evidence of moderated mediation, such that trauma coping self-efficacy was a mediator only when posttraumatic cognitions were low or average. Results indicate that posttraumatic appraisals and coping self-efficacy play significant roles in perception of cognitive problems following trauma. Clinically, in patients for which there is a perception of cognitive impairment that is not borne out in neuropsychological testing, cognitive-behavioral therapy focused on altering negative self-perceptions and appraisals may be beneficial.

    We conducted a survey with the Lynfield obsessive-compulsive symptom questionnaire (revised version) on 48 obsessive-compulsive neurotic patients as the survey subjects. In the factor analysis five factors of obsessions, were identified: (i) the desire for perfection; (ii) compulsive checking; (iii) washing; (iv) feelings of uncleanliness; and (v) anthropophobia. High correlations were noted between these factors. We also investigated the premorbid personalities of obsessive-compulsive neurotic patients with a multidimensional personality scale and obtained an extroversion dimension and neuroticism dimension. The influence of these premorbid personality dimensions on obsessive-compulsive symptoms became clear; (i) neuroticism is related to the levels of obsession after onset, but not related to compulsive behaviors; and (ii) No differences in premorbid personality dimensions were noted between compulsive checking and compulsive washing behaviors. We also studied whether it was possible to predict the efficacy of pharmacotherapy upon obsessive-compulsive symptoms. It was elucidated that the obsessions of those whose premorbid personalities are emotionally stable and extroversive are susceptible to antidepressants. Based on these results, we discussed the usefulness of premorbid personalities in predicting diversity of obsessive-compulsive symptoms, as well as in prediction the efficacy of medication.

    This study investigates whether using an HIV/AIDS symptom management manual with self-care strategies for 21 common symptoms, compared to a basic nutrition manual, had an effect on reducing symptom frequency and intensity. A 775-person, repeated measures, randomized controlled trial was conducted over three months in 12 sites from the United States, Puerto Rico, and Africa to assess the relationship between symptom intensity with predictors for differences in initial symptom status and change over time. A mixed model growth analysis showed a significantly greater decline in symptom frequency and intensity for the group using the symptom management manual (intervention) compared to those using the nutrition manual (control) (t=2.36, P=0.018). The models identified three significant predictors for increased initial symptom intensities and in intensity change over time: (1) protease inhibitor-based therapy (increased mean intensity by 28%); (2) having comorbid illness (nearly twice the mean intensity); and (3) being Hispanic receiving care in the United States (increased the mean intensity by 2.5 times). In addition, the symptom manual showed a significantly higher helpfulness rating and was used more often compared to the nutrition manual. The reduction in symptom intensity scores provides evidence of the need for palliation of symptoms in individuals with HIV/AIDS, as well as symptoms and treatment side effects associated with other illnesses. The information from this study may help health care providers become more aware of self-management strategies that are useful to persons with HIV/AIDS and help them to assist patients in making informed choices.

    Post-stroke depression (PSD) is the most common mental disorder following stroke; however, little is known about its pathogenesis. We investigated the predictive value and mutual relationship of psychological factors such as self-efficacy and social support and known risk factors such as pre-stroke depression, activities of daily living (ADL), cognitive functioning, and age for the emergence of depressive symptoms in the acute phase after stroke. Ninety-six ischaemic stroke inpatients residing at a rehabilitation centre completed an interview about 6.5 weeks post-stroke. The interview included demographic data, psychiatric anamnesis, the Barthel Index, Mini-Mental State Examination, Social Support Questionnaire, Generalized Self-Efficacy Scale, Stroke Self-Efficacy Questionnaire, and the Geriatric Depression Scale. A multiple regression analysis was performed to ascertain the predictive value of the factors on depressive symptoms. High self-efficacy, no history of pre-stroke depression, and high levels of perceived social support were the strongest protective factors for depressive symptoms. The influence of cognitive functioning on depressive symptoms was fully mediated by general self-efficacy, and general self-efficacy was a stronger predictor than stroke-specific self-efficacy. Neither ADL nor age significantly predicted depressive symptoms. Our findings suggest that consideration of self-efficacy and perceived social support in the inpatient rehabilitation setting may help prevent PSD.

    Although the negative impact of symptom severity on subjective well-being outcomes has been established among individuals with brain injury, the mediating and protective role that positive human traits might have on this relationship has not been adequately explored. The purpose of this study was to examine the impact of social self-efficacy and disability acceptance on the relationship between symptom severity and life satisfaction among individuals with brain injury. Hierarchical regression analysis and correlation techniques were used to test a hypothesized dual-mediation model of life satisfaction in a sample of 105 adults with acquired brain injury. Results indicated that social self-efficacy and disability acceptance fully mediated the relationship between symptom severity and life satisfaction, lending support for a dual-mediation model with disability acceptance being the strongest contributor. These findings suggest there may be considerable value for rehabilitation providers to develop strengths-based service strategies and/or specialized intervention programs that focus on capitalizing these positive human traits to promote life satisfaction and well-being for clients with brain injury. Implications for clinical practice and future research direction are also discussed.

    Depressed mood is highly prevalent among HIV-infected individuals. Some but not all studies have found group psychotherapy to be efficacious in this population. We performed a systematic review and meta-analysis of double-blinded, randomized controlled trials to examine efficacy of group psychotherapy treatment among HIV infected with depressive symptoms. We used PubMed, the Cochrane database, and a search of bibliographies to find controlled clinical trials with random assignment to group psychotherapy or control condition among HIV infected patients with depressive symptoms. The principal measure of effect size was the standard difference between means on validated depression inventories. We identified 8 studies that included 665 subjects: 5 used cognitive behavioral therapy (CBT), 2 used supportive therapy, and 1 used coping effectiveness training. Three of the 8 studies reported significant effects. The pooled effect size from the random effects model was 0.38 (95% confidence interval [CI]: 0.23-0.53) representing a moderate effect. Heterogeneity of effect was not found to be significant (p = 0.69; I(2) = 0%). Studies reporting use of group CBT had a pooled effect size from the random effects model of 0.37 (95% CI: 0.18-0.56) and was significant. Studies reporting the use of group supportive psychotherapy had a pooled effect size from the random effects model 0.58 (95% CI: -0.05-1.22) and was nonsignificant. The results of this study suggest that group psychotherapy is efficacious in reducing depressive symptoms among, HIV-infected individuals. Of note, women were nearly absent from all studies. Future studies should be directed at addressing this disparity.

In an open-label randomized controlled trial, 90 women with premenstrual syndrome who required COC were randomly recruited and allocated equally to receive either 6 cycles of 20 micrograms ethinyl estradiol (EE/150 micrograms DSG (DSG group or 20 micrograms EE/3 mg DRSP (DRSP group in 24/4 extended regimen. Analysis of covariance and repeated analysis of variance were used to determine the difference of mean Women's Health Assessment Questionnaire (WHAQ scores changes between groups, within group, and in premenstrual, menstrual, and postmenstrual phases. Results. Baseline characteristics and WHAQ scores were comparable. At the ends of the 3rd and the 6th cycles, mean WHAQ scores of all the 3 phases in DRSP group showed significant reduction and were significantly lower than those in DSG group. DSG group showed significant reduction in both premenstrual and menstrual phases after the 6th cycle. Adverse effects were comparable in both groups. In conclusion, low-dose COC containing either DSG or DRSP reduced premenstrual symptoms, but the latter showed greater efficacy and earlier reduction.

    2013-01-01

    Full Text Available We aimed to assess the efficacy of Centella asiatica for improvement of the signs and symptoms of chronic venous insufficiency (CVI. We searched 13 electronic databases including the Cochrane Central Register of Controlled Trials for randomised controlled trials assessing the efficacy of Centella asiatica for CVI. Two review authors independently selected studies, assessed the risks of bias of included studies and extracted data. The treatment effects of similar studies were pooled whenever appropriate. Eight studies met the inclusion criteria. The pooling of data of similar studies showed that Centella asiatica significantly improved microcirculatory parameters such as transcutaneous partial pressure of CO2 and O2, rate of ankle swelling and venoarteriolar response. Three out of the eight studies did not provide quantitative data. However, these studies reported that patients treated with Centella asiatica showed significant improvement in CVI signs such as leg heaviness, pain and oedema. Our results show that Centella asiatica may be beneficial for improving signs and symptoms of CVI but this conclusion needs to be interpreted with caution as most of the studies were characterised by inadequate reporting and thus had unclear risks of bias, which may threaten the validity of the conclusions.

Changes in the inventories were used to evaluate the efficacy of the treatment. The t test, Chi-square test, and SPSS (version 16 were used to analyze the data. The statistical significance was set at P<0.05. Results: Ondansetron plus risperidone was associated with a significantly larger improvement in the PANSS overall scale and subscales for negative symptoms and cognition than was risperidone plus placebo (P<0.001. The WAIS-R scale results indicated significant differences between the 2 groups before and after administrating the medicine and the placebo. The administration of ondansetron significantly improved visual memory based on the subtests of the WAIS (P<0.05. Ondansetron had no positive effects on depressive symptoms (effect size=0.13. Conclusion: This study confirmed that ondansetron, as an adjunct treatment, reduces negative symptoms in patients with schizophrenia and can be used as a potential adjunctive strategy particularly for negative symptoms and cognitive impairments.

    Background. This work examines the relationship between emotional intelligence (EI) and depressive symptomatology in institutionalized older adults, delving into the mechanisms underlying this relationship. Considering that previous evidence of the variation of the EI-depression relationship depending on whether the emotional ability or the perception of that ability is evaluated, a model of multiple mediation was tested in which the dimensions of emotional self-efficacy (ESE) act as mediators in the relationship between ability EI and depressive symptomatology. Methods. The sample consisted of 115 institutionalized older adults (47.82% women; 80.3 ± 7.9 years of age) from the province of Jaén (Spain) who completed a test of ESE, a measure of ability EI, and a self-administered questionnaire of depressive symptoms. Results. The results showed a positive association between older adults' emotional performance and depressive symptomatology, finding stronger associations with ESE than with EI abilities. In addition, multiple mediation analyses showed that two of the four dimensions of ESE fully mediated the relationship between ability EI and depressive symptoms. Discussion. These findings suggest that older adults' high levels of emotional competence generate a feeling of ESE which can protect them against depressive symptoms. This work supports the predictive validity of emotional abilities and ESE for the mental health of a group that is particularly vulnerable to depression, institutionalized older adults. The limitations of the work are discussed, and future lines of research were considered.

    Full Text Available Sebastián Carranza-LiraReproductive Medicine, UMAE Hospital de Ginecología y Obstetricia “Luis Castelazo Ayala” Instituto Mexicano del Seguro Social, MéxicoAbstract: During menopause vasomotor symptoms are one of the main complaints about which women seek medical advice. For symptom control, several therapies have been used, among which hormone therapy has produced good results. One of these is estrogen monotherapy, which unfortunately may induce endometrial hyperplasia in women with an intact uterus. A progestin must be added to avoid this risk. Progestins may induce several secondary effects such as breast tenderness, hirsutism, edema and unfavorable lipid profile modifications. Recently a new progestin called drospirenone has been synthesized and used in combination with estradiol for the treatment of postmenopausal women. This progestin is derived from spironolactone, and lacks estrogenic, androgenic and glucocorticoid activities. Several studies have evaluated safety, efficacy and patient tolerability, and have shown a good profile in all these parameters. All studies agree that the combination of estradiol 1 mg plus drospirenone 2 mg is a good choice for postmenopausal women with vasomotor symptoms.Keywords: estradiol, drospirenone, postmenopause, review

    Full Text Available Background: Negative symptoms and diminished cognitive ability are also considered as core features of schizophrenia. There are many studies in which negative symptoms and cognitive impairments are individually treated with atypical antipsychotic in comparison with either a placebo or a typical antipsychotic. There is paucity of studies comparing the efficacy of olanzapine and amisulpride on improvement of negative symptoms and cognitive impairments. Aim: To examine the effectiveness of amisulpride and olanzapine in treatment of negative symptoms and cognitive impairments in schizophrenia. Materials and Methods: Total 40 adult inpatients diagnosed as schizophrenia fulfilling inclusion/exclusion criteria were included in the study with their informed consent. These patients were recruited consecutively to one of the two drug regimen group, i.e. tab Amisulpride (100-300 mg/day and tab Olanzapine (10-20 mg. Patients were evaluated on day 0 and day 60 with various rating scales like Scale for the Assessment of Negative Symptoms (SANS, Scale for the Assessment of Positive Symptoms (SAPS, Schizophrenia Cognition Rating Scale (SCoRS, Brief Psychiatric Rating Scale (BPRS, Calgary Depression Scale for Schizophrenia (CDSS, and three different scales to measure drug side effects. Results: The mean SANS score in amisulpride and olanzapine group at day 0 and day 60 were 83.89 (±12.67 and 21.00 (±11.82 and 84.40 (±13.22 and 26.75 (±12.41, respectively.

    The availability of a simple and reliable tool for quantitatively measuring symptom perception is surely very important in the daily practice. Especially, this concept appears to be fundamental in doctor's office and at home, where there are no adequate resources. The Visual Analogue Scale is a very simple and popular tool that could be used by anyone anywhere. The advantage given by the Visual Analogue Scale consists in the translation of a subjective sensation in an objective measure provided by numbers.

    Guaifenesin is a component of medicines used to improve symptoms associated with upper respiratory tract infections. Patient-reported outcome instruments are valuable for evaluating symptom improvements; however, a validated tool to assess efficacy of mucoactive drugs does not exist. We compared the efficacy of extended-release guaifenesin with placebo for treatment of symptoms of upper respiratory tract infection using subjective efficacy assessments in a pilot study and confirmed precision of assessments in a validation study. The pilot study was a randomized, double-blind study where patients were dosed with either 1200 mg extended-release guaifenesin (n = 188) or placebo (n = 190), every 12 hours for 7 days. Efficacy was assessed using subjective measures including the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and the Wisconsin Upper Respiratory Symptom Survey. End-of-study assessments were completed by patients and investigator. The validation study consisted of two phases. In Phase I, subjects completed interviews to gather evidence to support the content validity of the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and Patient's End-of-Treatment Assessment. Phase II examined the psychometric properties of assessments evaluated in Phase I of the validation study using data from the pilot study. Subjective measures of efficacy at Day 4 showed the most prominent difference between treatment groups, in favor of guaifenesin. The 8-symptom related questions (SUM8) in the Daily Cough and Phlegm Diary, analyzed as a composite score appeared to be the strongest candidate endpoint for further evaluation. Results from the interviews in Phase I supported the content of the assessments which were validated during Phase II. Treatments were well tolerated. Results from the clinical pilot and validation studies showed that the SUM8 diary scores were robust and reliable for use as efficacy endpoints in studies of

    The current multi-wave longitudinal study on childhood examined the role that social and academic self-efficacy beliefs and cognitive vulnerabilities play in predicting depressive symptoms in response to elevations in idiographic stressors. Children (N = 554; males: 51.4 %) attending second and third grade completed measures of depressive symptoms, negative cognitive styles, negative life events, and academic and social self-efficacy beliefs at four time-points over 6 months. Results showed that high levels of academic and social self-efficacy beliefs predicted lower levels of depressive symptoms, whereas negative cognitive styles about consequences predicted higher depression. Furthermore, children reporting higher social self-efficacy beliefs showed a smaller elevation in levels of depressive symptoms when reporting an increases in stress than children with lower social self-efficacy beliefs. Findings point to the role of multiple factors in predicting children's depression in the long term and commend the promotion of self-efficacy beliefs and the modification of cognitive dysfunctional styles as relevant protective factors.

    Deltoid muscle weakness due to C-5 nerve root injury following cervical spine surgery is an uncommon but potentially debilitating complication. Symptoms can manifest upon emergence from anesthesia or days to weeks following surgery. There is conflicting evidence regarding the efficacy of spontaneous electromyography (spEMG) monitoring in detecting evolving C-5 nerve root compromise. By contrast, transcranial electrical stimulation-induced motor evoked potential (tceMEP) monitoring has been shown to be highly sensitive and specific in identifying impending C-5 injury. In this study the authors sought to 1) determine the frequency of immediate versus delayed-onset C-5 nerve root injury following cervical spine surgery, 2) identify risk factors associated with the development of C-5 palsies, and 3) determine whether tceMEP and spEMG neuromonitoring can help to identify acutely evolving C-5 injury as well as predict delayed-onset deltoid muscle paresis. The authors retrospectively reviewed the neuromonitoring and surgical records of all patients who had undergone cervical spine surgery involving the C-4 and/or C-5 level in the period from 2006 to 2008. Real-time tceMEP and spEMG monitoring from the deltoid muscle was performed as part of a multimodal neuromonitoring protocol during all surgeries. Charts were reviewed to identify patients who had experienced significant changes in tceMEPs and/or episodes of neurotonic spEMG activity during surgery, as well as those who had shown new-onset deltoid weakness either immediately upon emergence from the anesthesia or in a delayed fashion. Two hundred twenty-nine patients undergoing 235 cervical spine surgeries involving the C4-5 level served as the study cohort. The overall incidence of perioperative C-5 nerve root injury was 5.1%. The incidence was greatest (50%) in cases with dual corpectomies at the C-4 and C-5 spinal levels. All patients who emerged from anesthesia with deltoid weakness had significant and unresolved

    We examined parenting stress (PST) and self-efficacy (PSE) following participation in behavioral parent training (BPT) with regard to child treatment response. Forty-three families of children diagnosed with ADHD participated in a modified BPT program. Change in PST and PSE was evaluated using a single group, within-subjects design. Parenting outcomes based on child treatment response were evaluated based upon (1) magnitude and (2) clinical significance of change in child symptom impairment. Parents reported significant improvements in stress and self-efficacy. Parents of children who demonstrated clinically significant reduction in ADHD symptoms reported lower stress and higher self-efficacy than those of children with continued impairments. Magnitude of child impairment was not associated with parent outcomes. Clinical implications for these results include extending treatment duration to provide more time for symptom amelioration and parent-focused objectives to improve coping and stress management.

This study examined (1) correlations between depression and HRV indices; (2) group differences in HRV indices among a heroin-user group, a group with major depressive disorder but no heroin use, and healthy controls; and (3) the effects of heart-rate-variability–biofeedback on depressive symptoms, HRV indices, and respiratory rates within the heroin group. Methods All participants completed a depression questionnaire and underwent electrocardiogram measurements, and group differences in baseline HRV indices were examined. The heroin group underwent electrocardiogram and respiration rate measurements at baseline, during a depressive condition, and during a happiness condition, before and after which they took part in the heart-rate-variability–biofeedback program. The effects of heart-rate-variability–biofeedback on depressive symptoms, HRV indices, and respiration rates were examined. Results There was a negative correlation between depression and high frequency of HRV, and a positive correlation between depression and low frequency to high frequency ratio of HRV. The heroin group had a lower overall and high frequency of HRV, and a higher low frequency/high frequency ratio than healthy controls. The heart-rate-variability–biofeedback intervention increased HRV indices and decreased respiratory rates from pre-intervention to post-intervention. Conclusion Reduced parasympathetic and increased sympathetic activations were found in heroin users. Heart-rate-variability–biofeedback was an effective non-pharmacological intervention to restore autonomic balance. PMID:27121428

    Prevalence of sinusitis on sinus computed tomography (CT) in asthmatic patients and efficacy of intranasal corticosteroid treatment on asthmatic symptoms in asthmatic patients with rhinosinusitis on sinus CT is unclear. Sinus CT of asthmatic patients were evaluated using the Lund-Mackay system (LMS). Intranasal corticosteroid treatment (mometasone furoate) was newly added to symptomatic asthmatic patients with rhinosinusitis treated without intranasal corticosteroids, and the findings of the Asthma Control Test (ACT), Asthma Control Questionnaire in 5 items (ACQ5), spirometry, and sinus CT were evaluated before and 3 months after additional intranasal corticosteroid treatment. In a total of 160 asthmatic patients, rhinosinusitis and maxillary, ethmoidal, sphenoidal, and frontal sinusitis were observed in 75.0%, 70.0%, 53.1%, 33.1%, and 28.8%, respectively. Nasal symptoms and rhinophonia were observed in 81.9% and 72.5%, respectively, and patients with nasal symptoms and those with rhinophonia both showed significantly higher LMS scores in each sinus. Chronic rhinosinusitis (CRS) was observed in 66.9%, and these patients had significantly more severe asthma than the patients without CRS. In patients with CRS, patients with rhinophonia showed significantly higher LMS scores than those without rhinophonia. ACT, ACQ5, and the value of the forced expiratory volume in 1 second (FEV1) all significantly improved 3 months after the additive intranasal corticosteroid treatment in 24 patients, despite the fact that their LMS scores remained unchanged. Additive intranasal corticosteroid treatment may be an effective treatment option for symptomatic asthmatic patients with rhinosinusitis. © 2015 ARS-AAOA, LLC.

    This study explored the parenting self-efficacy of the parents of 18-month-old children in the context of Finnish maternity and child health clinics. This parenting self-efficacy was observed in relation with the relational continuity of care and parents' experienced loneliness and depressive symptoms. The relational continuity of care was provided by a public health nurse in maternity and child health clinics. The participating parents were drawn from the STEPS study that is being carried out by the Institute for Child and Youth Research at the University of Turku. The results showed that relational continuity of care provided by the same public health nurse in the maternity and child health clinics was associated with mothers' higher emotional loneliness and with lower scores on three dimensions of parents' parenting self-efficacy. Loneliness and depressive symptoms negatively influenced parents' parenting self-efficacy - however, in the case where the family had experienced relational continuity of care, the parents' higher levels of depressive symptoms had not weakened their parenting self-efficacy beliefs. These results are discussed in terms of organizing maternity and child health clinic services.

    Awakening from sleep to urinate is the hallmark of nocturia, a condition that impacts several facets of health related quality of life and for which current therapy is suboptimal. Given the paucity of prospective data on antimuscarinics for the management of nocturia, we investigated the efficacy and safety of flexible dose fesoterodine for the treatment of nocturnal urgency in subjects with nocturia and overactive bladder. Subjects with 2 to 8 nocturnal urgency episodes per 24 hours began a 2-week, single-blind, placebo run-in followed by 1:1 randomization to 12 weeks of double-blind treatment with fesoterodine (4 mg daily for 4 weeks with an optional increase to 8 mg) or placebo using predefined criteria for nocturnal urgency episodes, nocturnal urine volume voided and total 24-hour urine volume voided. The primary end point was change from baseline to week 12 in the mean number of micturition related nocturnal urgency episodes per 24 hours. Overall 963 subjects were randomized from 2,990 screened, and 82% of subjects treated with fesoterodine and 84% of those treated with placebo completed the study. Significant improvements in the primary end point (-1.28 vs -1.07), in nocturnal micturitions per 24 hours (-1.02 vs -0.85) and in nocturnal frequency urgency sum (-4.01 vs -3.42) were observed with fesoterodine vs placebo (all p ≤0.01). Health related quality of life measures (overactive bladder questionnaire Symptom Bother -20.1 vs -16.5, sleep 22.3 vs 19.9 and other domains; all p fesoterodine. To our knowledge this is the first prospective study to assess antimuscarinic efficacy for reducing nocturnal urgency. Flexible dose fesoterodine significantly reduced nocturnal urgency episodes vs placebo in subjects with overactive bladder.

    To evaluate long-term safety, tolerability, and efficacy of fesoterodine for men and women with overactive bladder (OAB) symptoms. This was a post hoc analysis of data pooled from two open-label extensions (NCT00220402, NCT00220376) of double-blind studies. All subjects began open-label treatment with fesoterodine 8 mg once daily, with voluntary dose reduction to 4 mg and re-escalation to 8 mg each permitted once annually. Maximum allowable duration of open-label treatment ranged from 24 to 36 months. Safety and discontinuations were assessed throughout treatment; subject-reported treatment tolerability and 3-day bladder diaries were evaluated at open-label baseline and months 1, 4, 8, 12, and 24. A total of 185 men and 705 women enrolled; 83 men (45%) and 356 women (50%) continued open-label treatment for ≥ 24 months. Most men (84%) and women (75%) remained on fesoterodine 8 mg throughout open-label treatment. No new or unexpected safety signals were observed. Dry mouth was the most common treatment-emergent adverse event (men, 24%; women, 32%), rates of discontinuation due to dry mouth were low (men, 1%; women, 2%). Most men and women (≥ 91%) reported at least 'good' tolerance. For men and women, statistically significant improvements in urgency urinary incontinence episodes, micturitions, urgency episodes, and mean voided volume per micturition achieved between double-blind baseline and open-label baseline were sustained or further improved through month 24; significant improvements in most OAB symptoms were observed between double-blind baseline and month 24 when subjects were stratified by double-blind treatment (placebo, tolterodine extended release 4 mg, fesoterodine 4 mg, fesoterodine 8 mg). Limitations include the lack of a placebo control and that subjects completing double-blind treatment may have been more likely to tolerate or respond to long-term fesoterodine treatment. Long-term fesoterodine treatment was well tolerated and associated with

    There is no consensus on how best to treat symptom recurrence following previous therapy with Heller myotomy. Our aim was to determine the safety and the short and long-term efficacy of pneumatic dilatation to treat symptomatic recurrence in patients previously treated with Heller myotomy for idiopathic achalasia. We identified 27 eligible patients treated with pneumatic dilatation, for symptom recurrence following Heller myotomy as their initial or secondary treatment, from a prospectively acquired database of 450 patients with a diagnosis of achalasia seen between 1995 and 2010. Our treatment protocol involved sequential, graded pneumatic dilatations (30-35-40 mm) over a 2-6 week period until an initial therapeutic response was achieved. The subsequent relapse rate, defined as the need for any subsequent therapy, was determined. Relapsers were offered further pneumatic dilatation "on demand". A cross-sectional analysis was also performed using a validated achalasia severity questionnaire to determine the overall long-term remission rate. Of 27 eligible patients, 25 (93%) complied with the institutional dilatation protocol. The two drop-outs did so after the initial 30 mm dilatation and were deemed treatment failures. One additional patient did not respond despite protocol compliance. Therefore, 24 of 27 (89%) patients were responders on intention to treat analysis at 12 months, while the per protocol response rate was 24 of 25 (96%). Among the 24 responders 16, 25, and 42% relapsed at 2, 3 and 4  years, respectively. Overall long-term remission, with on demand dilatations as required, was 95% (median follow-up 30 months). There were no perforations in a total of 50 dilatations in 27 patients. In treating symptom recurrence, following prior Heller myotomy, pneumatic dilatation is safe and yields an excellent short-term response rate. Although the long-term relapse rate is substantial, subsequent on demand pneumatic dilatation in this population is highly

    To present a new grouping of male patients with lower urinary tract symptoms (LUTS) based on symptom patterns and clarify whether the therapeutic effect of α1-blocker differs among the groups. We performed secondary analysis of anonymous data from 4815 patients enrolled in a postmarketing surveillance study of tamsulosin in Japan. Data on 7 International Prostate Symptom Score (IPSS) items at the initial visit were used in the cluster analysis. IPSS and quality of life (QOL) scores before and after tamsulosin treatment for 12 weeks were assessed in each cluster. Partial correlation coefficients were also obtained for IPSS and QOL scores based on changes before and after treatment. Five symptom groups were identified by cluster analysis of IPSS. On their symptom profile, each cluster was labeled as minimal type (cluster 1), multiple severe type (cluster 2), weak stream type (cluster 3), storage type (cluster 4), and voiding type (cluster 5). Prevalence and the mean symptom score were significantly improved in almost all symptoms in all clusters by tamsulosin treatment. Nocturia and weak stream had the strongest effect on QOL in clusters 1, 2, and 4 and clusters 3 and 5, respectively. The study clarified that 5 characteristic symptom patterns exist by cluster analysis of IPSS in male patients with LUTS. Tamsulosin improved various symptoms and QOL in each symptom group. The study reports many male patients with LUTS being satisfied with monotherapy using tamsulosin and suggests the usefulness of α1-blockers as a drug of first choice. Copyright © 2015 Elsevier Inc.

    Nerve growth factor (NGF) exhibits many biological activities, such as supply of nutrients, neuroprotection, and the generation and rehabilitation of injured nerves. The neuroprotective and neurotrophic qualities of NGF are generally recognized. NGF may enhance axonal regeneration and myelination of peripheral nerves, as well as cooperatively promote functional recovery of injured nerves and limbs. The clinical efficacy of NGF and its therapeutic potentials are reviewed here. This paper also reviews the latest NGF research developments for repairing injured peripheral nerve, thereby providing scientific evidence for the appropriate clinical application of NGF.

    Full Text Available Abstract Background Guaifenesin is a component of medicines used to improve symptoms associated with upper respiratory tract infections. Patient-reported outcome instruments are valuable for evaluating symptom improvements; however, a validated tool to assess efficacy of mucoactive drugs does not exist. We compared the efficacy of extended-release guaifenesin with placebo for treatment of symptoms of upper respiratory tract infection using subjective efficacy assessments in a pilot study and confirmed precision of assessments in a validation study. Methods The pilot study was a randomized, double-blind study where patients were dosed with either 1200 mg extended-release guaifenesin (n = 188 or placebo (n = 190, every 12 hours for 7 days. Efficacy was assessed using subjective measures including the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and the Wisconsin Upper Respiratory Symptom Survey. End-of-study assessments were completed by patients and investigator. The validation study consisted of two phases. In Phase I, subjects completed interviews to gather evidence to support the content validity of the Daily Cough and Phlegm Diary, the Spontaneous Symptom Severity Assessment and Patient’s End-of-Treatment Assessment. Phase II examined the psychometric properties of assessments evaluated in Phase I of the validation study using data from the pilot study. Results Subjective measures of efficacy at Day 4 showed the most prominent difference between treatment groups, in favor of guaifenesin. The 8-symptom related questions (SUM8 in the Daily Cough and Phlegm Diary, analyzed as a composite score appeared to be the strongest candidate endpoint for further evaluation. Results from the interviews in Phase I supported the content of the assessments which were validated during Phase II. Treatments were well tolerated. Conclusions Results from the clinical pilot and validation studies showed that the SUM8 diary

  5. A randomised controlled trial to assess the efficacy of Laparoscopic Uterosacral Nerve Ablation (LUNA in the treatment of chronic pelvic pain: The trial protocol [ISRCTN41196151

    Directory of Open Access Journals (Sweden)

    2003-12-01

    Full Text Available Abstract Background Chronic pelvic pain is a common condition with a major impact on health-related quality of life, work productivity and health care utilisation. The cause of the pain is not always obvious as no pathology is seen in 40–60% of the cases. In the absence of pathology there is no established treatment. The Lee-Frankenhauser sensory nerve plexuses and parasympathetic ganglia in the uterosacral ligaments carry pain from the uterus, cervix and other pelvic structures. Interruption of these nerve trunks by laparoscopic uterosacral nerve ablation (LUNA may alleviate pain. However, the balance of benefits and risks of this intervention have not been reliably assessed. LUNA has, nevertheless, been introduced into practice, although there remains controversy regarding indications for LUNA. Hence, there is an urgent need for a randomised controlled trial to confirm, or refute, any worthwhile effectiveness. The principal hypothesis is that, in women with chronic pelvic pain in whom diagnostic laparoscopy reveals either no pathology or mild endometriosis (AFS score ≤ 5 LUNA alleviates pain and improves life quality at 12 months. Methods/Design The principal objective is to test the hypothesis that in women with chronic pelvic pain in whom diagnostic laparoscopy reveals either no pathology or mild endometriosis (AFS score ≤ 5 LUNA alleviates pain and improves life quality at 12 months. A multi-centre, prospective, randomised-controlled-trial will be carried out with blind assessment of outcomes in eligible consenting patients randomised at diagnostic laparoscopy to LUNA (experimental group or to no pelvic denervation (control group. Postal questionnaires including visual analogue scale for pain (primary outcome, an index of sexual satisfaction and the EuroQoL 5D-EQ instrument (secondary outcomes will be administered at 3, 6 and 12 months. The primary assessment of the effectiveness of LUNA will be from comparison of outcomes at the one

    This study examined the influence of a culturally focused wellness intervention on alcohol consumption, alcohol abstinence self-efficacy, depression, and self-esteem among women of a small American Indian community in the southwestern United States. Participation in two intervention approaches was compared: a curriculum-based health promotion–only approach and health promotion combined with cognitive-behavioral skills building (CBSB). The wellness intervention was tested in a prospective, randomized, two-group design with repeated measures. There was no control group. An American Indian community in the Southwest. American Indian women, ages 18 to 50 (N = 268). A 10-session culturally focused curriculum-based health promotion intervention, with a CBSB component, was developed using a community-based participatory research process. Comparisons were made between those who attended the health promotion plus CBSB intervention and those who attended the intervention without the CBSB component. Information regarding demographics, substance use, alcohol consumption, alcohol abstinence self-efficacy, depressive symptoms, and self-esteem was collected through a structured interview. Regression was used to evaluate the effect of the intervention on alcohol consumption, alcohol abstinence self-efficacy, depressive symptoms, and self-esteem in CBSB and non-CBSB groups. Although there were no significant differences between the CBSB and non-CBSB groups, the results indicate a significant decrease in alcohol consumption and symptoms of depression, and a significant increase in alcohol abstinence self-efficacy and self-esteem, from baseline to the 6-month follow-up for both groups. Evidence suggests that this culturally focused health promotion intervention has a positive impact on alcohol use, alcohol abstinence self-efficacy, depressive symptoms, and self-esteem among American Indian women.

    2015-05-01

    Restless legs syndrome (RLS) is a common, frequently chronic, sensorimotor neurological disorder characterized by nocturnal leg dysesthesias and an irresistible urge to move the legs, usually resulting in sleep disturbance. Dopaminergic agonists, alpha-2-delta calcium-channel ligands, and opioids have all demonstrated efficacy to relieve symptoms of RLS and improve sleep. However, long-term treatment with dopamine agonists (the most commonly prescribed agents) is often characterized by worsening symptoms and loss of efficacy. A more worrisome complication of dopaminergic agents is augmentation, an iatrogenic worsening of RLS symptoms that can produce progressively more severe symptoms resulting in around-the-clock restlessness and near sleeplessness. Recent research has yielded consensus regarding a precise definition of augmentation and has contributed to improved knowledge regarding strategies for preventing this complication. When RLS symptoms worsen during the course of treatment, the clinician must consider the myriad of environmental, medical, pharmacologic, and psychiatric factors that can exacerbate RLS. In the absence of fully developed, evidence-based guidelines there remains uncertainty regarding the optimal management strategy if augmentation develops. However, we discuss several key principles based on the available published data and the authors' clinical experience. We also explore the recent increasing interest in alternative initial treatment strategies that avoid dopamine agonists and their associated complications altogether.

    Full Text Available Statement of the Problem: Treatment with salivary substitutes and stimulation of salivary flow by either mechanical or pharmacologic methods has side effects and only provides symptomatic relief but no long-lasting results. Purpose: To assess the effectiveness of extraoral transcutaneous electric nerve stimulation (TENS as a mean of stimulating salivary function in healthy adult subjects; as well as to determine the gender and age-dependent changes in salivary flow rates of unstimulated and stimulated parotid saliva. Materials and Method: Hundred patients were divided into two groups; Group I aged 20-40 and Group II aged ≥ 60 years. The TENS electrode pads were externally placed on the skin overlying the parotid glands. Unstimulated and stimulated parotid saliva was collected for 5 minutes each by using standardized collection techniques. Results: Eighty seven of 100 subjects demonstrated increased salivary flow when stimulated via the TENS unit. Ten experienced no increase and 3 experienced a decrease. The mean unstimulated salivary flow rate was 0.01872 ml/min in Group I and 0.0088 ml/min in Group II. The mean stimulated salivary flow rate was 0.03084 ml/min (SD= 0.01248 in Group I, and 0.01556 ml/min (SD 0.0101 in Group II. After stimulation, the amount of salivary flow increased significantly in both groups (p< 0.001. Statistical comparison of the two groups revealed them to be significantly different (p< 0.001, with Group I producing more saliva. Gender-wise, no statistically significant difference was seen among the subjects in Group I (p = 0.148, and those in Group II (p= 0.448. Out of 12 subjects with 0 baseline flows, 7 continued to have no flow. Five subjects observed side effects, although minimal and transient. Conclusion: The TENS unit was effective in increasing parotid gland salivary flow in healthy subjects. There was age-related but no gender-related variability in parotid salivary flow rate.

    Neuralgic amyotrophy is a painful, episodic peripheral nerve disorder localized to the brachial plexus. Sensory symptoms occur in 80% of the patients. We assessed the frequency of abnormalities in sensory nerve conduction studies of the lateral and medial antebrachial cutaneous, radial sensory, median sensory, and ulnar sensory nerves in 112 patients. Sensory nerve conduction studies showed abnormalities in nerves, even when the nerve was clinically affected. The lateral and medial antebrachial cutaneous nerves were most often abnormal, in 15% and 17% of nerves. No correlation with the presence or localization of clinical deficits was found. Brachial plexus sensory nerve conduction studies seem to be of little diagnostic value in neuralgic amyotrophy. Our findings also indicate that some sensory lesions may be in the nerve roots instead of the plexus. An examination of normal sensory nerve conduction studies does not preclude neuralgic amyotrophy as a diagnosis.

Of the 35 patients, 18 (51.4% at 6 months, 18 (51.4% at 12 months, and 21 (60.1% at 24 months showed ≥50% reduction in seizure frequency (responders. Although incremental seizure freedom was noted, no patient remained seizure-free throughout the 3 study periods. Partial response (≥50% seizure reduction in 2 or less study periods was seen in 8 (22.9% patients. Twelve patients (34.3% were nonresponders. Out of 29 patients with primary generalized epilepsy, 20 (68.9% and, out of 6 patients with focal epilepsy, 3 (50% had ≥50% seizure control in at least one study period. No major complications or side effects requiring discontinuation of VNS therapy were encountered. We conclude that (1 patients with intractable primary generalized epilepsy respond better to VNS therapy, (2 cumulative effect of neuromodulation with improving responder rate to seizure freedom with continuation of VNS therapy is noted, and (3 VNS therapy is safe and is well tolerated in children receiving implant under 12 years of age.

    Currently, the mechanism of action of vagus nerve stimulation (VNS) is not fully understood, and it is unclear which factors determine a patient's response to treatment. Recent preclinical experiments indicate that activation of the locus coeruleus noradrenergic system is critical for the antiepileptic effect of VNS. This study aims to evaluate the effect of VNS on noradrenergic signaling in the human brain through a noninvasive marker of locus coeruleus noradrenergic activity: the P3 component of the event-related potential. We investigated whether VNS differentially modulates the P3 component in VNS responders versus VNS nonresponders. For this purpose, we recruited 20 patients with refractory epilepsy who had been treated with VNS for at least 18 months. Patients were divided into 2 groups with regard to their reduction in mean monthly seizure frequency: 10 responders (>50 %) and 10 nonresponders (≤50 %). Two stimulation conditions were compared: VNS OFF and VNS ON. In each condition, the P3 component was measured during an auditory oddball paradigm. VNS induced a significant increase of the P3 amplitude at the parietal midline electrode, in VNS responders only. In addition, logistic regression analysis showed that the increase of P3 amplitude can be used as a noninvasive indicator for VNS responders. These results support the hypothesis that activation of the locus coeruleus noradrenergic system is associated with the antiepileptic effect of VNS. Modulation of the P3 amplitude should be further investigated as a noninvasive biomarker for the therapeutic efficacy of VNS in patients with refractory epilepsy.

    Depression is a common problem for many Hong Kong Chinese elderly, especially those living in nursing homes. This study examines the relationship between fear of falling and depressive symptoms as well as the role of participation in physical activity and fall efficacy in the linkage between the fear of falling and depression. A sample of 100 residents living in nursing homes were interviewed. Using multiple regression models, we found that elderly persons who had greater fear of falling tended to report depressive symptoms more frequently after controlling socio-demographic and physical health status variables. In addition, activity involvement and fall efficacy acted as mediators and moderators in the link between the fear of falling and depression. Policy makers and aged care professional practitioners should find these findings valuable in promoting activity to aid in the prevention of depression amongst the elderly population.

    In this cross-sectional study, we investigated the associations between patient communication self-efficacy and self-reported symptoms in doctor-patient communication, as perceived by patients, and the mental health and illness of hospital outpatients. Using data from a sample of 74 outpatients (mean age = 37.58 years, standard deviation = 12.54), a structural equation model was calculated. The results showed that communication self-efficacy and respectful behaviour were associated with mental health and illness. Furthermore, self-reported symptoms were correlated with mental illness. Gender and educational differences also occurred. The findings suggest that enhancing patients' communication skills could benefit outpatients in general, but female and less educated patients in particular.

For the clinical trial, approximately half of the patients who received Ex-B2 revealed amelioration of the symptoms. EA on the pudendal nerve was effective for the symptoms which had not improved by Ex-B2. Considerable immediate and sustained relief was observed in patients who received EA at the nerve root. For the animal study, increase in sciatic nerve blood flow was observed in 56.9% of the trial with lumber muscle acupuncture, 100% with pudendal nerve stimulation and 100% with sciatic nerve stimulation. Sciatic nerve stimulation sustained the increase longer than pudendal nerve stimulation. One mechanism of action of acupuncture and electrical acupuncture stimulation could be that, in addition to its influence on the pain inhibitory system, it participates in causing a transient change in sciatic nerve blood blow, including circulation to the cauda equine and nerve root.

    General self-efficacy (GSE), the expectation that one is able to perform a behavior successfully, may differentiate those who are able to successfully utilize self-care symptom management strategies (SCSMS). This subanalysis (n=569) of an international 12 site longitudinal randomized controlled trial (RCT) (n=775), investigated GSE as an important factor determining symptom burden, SCSMS, engagement with the provider, and medication adherence over time, and identified differences in those with high and low GSE ratings concerning these variables. Parametric and nonparametric repeated-measures tests were employed to assess GSE and the perceived effectiveness of SCSMS for anxiety, depression, diarrhea, fatigue, nausea, and neuropathy. Symptom burden, engagement with the provider, and antiretroviral adherence were analyzed with regard to GSE. Our data indicated that there were differences in the perceived symptom burden over time of HIV infected individuals by GSE. Those individuals with higher GSE had fewer symptoms and these symptoms were perceived to be less intense than those experienced by the low GSE group. There were few meaningful differences in the SCSMS used by those with high versus low GSE other than the use of illicit substances in the low GSE group. The low GSE group was also significantly (p= < 0.001) less engaged with their healthcare providers. Given the difference in substance use by perceived GSE, and the importance of engagement with the healthcare provider, more attention to the resolution of the concerns of those with low GSE by healthcare providers is warranted.

    Over a third of American college students are either overweight or obese, which has been suggested to negatively impact their academic achievement. This study seeks to better understand the relationship between body mass index (BMI) and grade point average (GPA), while examining potential mediators of this association. The sample consists of 298 college women who volunteered to complete online questionnaires between October and December 2014. Although no significant differences were noted for sociodemographic variables, overweight and obese female students were found to report lower GPA and academic self-efficacy as well as higher depressive symptoms, compared with their normal-weight counterparts. Academic self-efficacy partially mediated the relationship between BMI and GPA. To foster better academic achievement in female college students, and especially for those who are overweight and obese, strategies for improving self-efficacy and adaptation to college should be implemented.

    Drug-resistant epilepsy seems like a different disease compared with easy to control epilepsy, and new strategies are needed to help these patients. Vagus nerve stimulation (VNS) therapy is the most frequently used neurostimulation modality for patients with drug-resistant epilepsy who are not eligible for seizure surgery. In this study, we aimed to evaluate the efficacy and adverse effects of VNS in patients with drug-resistant epilepsy in an open-label, prospective, long-term study in Iran. We selected 48 patients with partial-onset drug-resistant epilepsy. Implantations were performed in the neurosurgery department of Loghman Hospital, Tehran, Iran. Follow-up visits were done on monthly bases for 5 years. Forty-four patients completed the study. Mean age of patients was 24.4 years. Mean years of epilepsy history was 14 years. The mean number of anti-epileptic drugs did not significantly change over five years (p = 0.15). There was no exacerbation of epilepsy; however, one patient discontinued his therapy due to unsatisfactory results. Five patient had more than 50 %, and 26 patients (59 %) had 25-49 % reduction in the frequency of monthly seizures persistently. Overall mean frequency of monthly seizures decreased by 57.8, 59.6, 65, 65.9, and 67 %, in 1st, 2nd, 3rd, 4th, and 5th years of follow-up, respectively. Most common side effects were as follows: hoarseness (25 %) and throat discomfort (10 %). We found VNS as a safe and effective therapy for drug-resistant epilepsy, with an approximate long-term decrease in mean seizure frequency of 57.8-67 %. Thus, VNS is recommended for suitable patients in developing countries.

    Introduction It is generally accepted that achieving complete anaesthesia with an Inferior Alveolar Nerve Block (IANB) in mandibular molars with symptomatic irreversible pulpitis is more challenging than for other teeth. Therefore, administration of Non-Steroidal Anti-Inflammatory Agents (NSAIDs) 1 hour prior to anaesthetic administration has been proposed as a means to increase the efficacy of the IANB in such patients. Aim The purpose of this prospective, double-blind, randomized clinical trial was to determine the effect of administration of oral premedication with ketorolac (KETO) and diclofenac potassium (DP) on the efficacy of IANB in patients with irreversible pulpitis. Materials and Methods One hundred and fifty patients with irreversible pulpitis were evaluated preoperatively for pain using Heft Parker visual analogue scale, after which they were randomly divided into three groups. The subjects received identical tablets of ketorolac, diclofenac pottasium or cellulose powder (placebo), 1 hour prior to administration of IANB with 2% lidocaine containing 1:200 000 epinephrine. Lip numbness as well as positive and negative responses to cold test were ascertained. Additionally pain score of each patient was recorded during cavity preparation and root canal instrumentation. Success was defined as the absence of pain or mild pain based on the visual analog scale readings. The data was analysed using One-Way Anova, Post-Hoc Tukey pair wise, Paired T – Test and chi-square test. Trial Registery Number is 4722/2015 for this clinical trial study. Results There were no significant differences with respect to age (p =0.098), gender (p = 0.801) and pre-VAS score (DP-KETO p=0.645, PLAC-KETO p =0.964, PLAC-DP p = 0.801) between the three groups. All patients had subjective lip anaesthesia with the IAN blocks. Patients of all the three groups reported a significant decrease in active pain after local anaesthesia (p< 0.05). The post injection VAS Score was least in group

    The purpose of this study is to document the topographic anatomy of an extensor indicis (EI) muscle with a double tendon and the associated distribution of the deep branch of the radial nerve (DBRN). Both EI tendons were positioned deep to the tendons of the extensor digitorum as they traversed the dorsal osseofibrous tunnel. They then joined the medial slips of the extensor expansion of the second and third digits. In all other dissected forearms, a tendon of the EI muscle joined the medial slip of the extensor expansion to the index finger. The DBRN provided short branches to the superficial extensor muscles, long branches to the abductor pollicis longus and extensor pollicis brevis muscles, and terminated as the posterior interosseous nerve. Descending deep to the extensor pollicis longus muscle, the posterior interosseous nerve sent branches to the extensor pollicis brevis and EI muscles. Understanding of the topographic anatomy of an EI with a double tendon, and the associated distribution of the DBRN, may contribute to accurate diagnosis and treatment of hand lesions.

    This study tested a conceptual model merging anxiety buffer disruption and social-cognitive theories to predict persistent grief severity among students who lost a close friend, significant other, and/or professor/teacher in tragic university campus shootings. A regression-based path model tested posttraumatic stress (PTS) symptom severity 3 to 4 months postshooting (Time 1) as a predictor of grief severity 1 year postshootings (Time 2), both directly and indirectly through cognitive processes (self-efficacy and disrupted worldview). Results revealed a model that predicted 61% of the variance in Time 2 grief severity. Hypotheses were supported, demonstrating that Time 1 PTS severity indirectly, positively predicted Time 2 grief severity through undermining self-efficacy and more severely disrupting worldview. Findings and theoretical interpretation yield important insights for future research and clinical application.

    ABSTRACT Introduction and objective Indwelling double J ureteral stents are used routinely in the resolution of ureteral obstruction caused by different etiologies. Evaluation of urinary symptoms related to double-J stent, indicate that these affect 73-90% of patients. We conducted a prospective, randomized study, to evaluate the efficacy of tamsulosin, oxybutinin and combination therapy in improving the urinary symptoms. Methods Patients who underwent ureteral stent placement after ureterolithotripsy (total 51), were randomized into three groups: Group I: Tamsulosin 0.4 mg. once per day(17 patients), Group II: Oxybutinin 5 mg. once per day (17 patients), Group III: Tamsulosin+ oxybutynin once per day (17 patients). All the groups received the drugs for three weeks and completed a Spanish validated Ureteral Stent Symptom Questionnaire (USSQ) at day 7 and 21. Results Repeated measures ANOVA showed mean urinary symptom index score was 22.3 vs. 15.5 in group three (p<0.001) at day 7 and 21 respectively. The mean work performance index was 6.6 vs 8.1 (p=0.049) favoring tamsulosin group, the mean sexual score was 0.5 vs 1.5 (p=0.03). Among additional problems the mean was 7.2 vs 6.2 (p=0.03). No significant difference was noted among pain and general health index. No side effects were reported. Conclusions Combination therapy with tamsulosin and oxybutynin improved irritative symptoms and work performance as well as sexual matters. Combination therapy should be considered for patients who complained of stent related symptoms. PMID:27286111

    The use of earplugs in loud music venues is confined to a small minority who wish to avoid hearing damage from excessive noise exposure. Using the framework of the health belief model (HBM), structured interviews were held with 20 earplug-wearing clubbers. Qualitative analysis revealed the HBM constructs relevant to understanding this group's motivation to protect their hearing. Personal experience of noise injury symptoms was the most common cue triggering earplug use. Awareness of the benefits of earplugs and appreciation of the long-term implications of hearing damage, affinity for music and high self-efficacy were also key variables underlying this health behaviour.

    The aim of this study was to assess the 12-week efficacy of desvenlafaxine in treating moderate to severe vasomotor symptoms and the clinical relevance of improvements in postmenopausal women experiencing 50 or more moderate to severe hot flashes per week. Participants were randomized to placebo or desvenlafaxine 100 mg/day in the 12-week efficacy substudy of a year-long, multicenter, parallel-group, double-blind study. Coprimary outcomes were changes from baseline in the daily number and severity of hot flashes on weeks 4 and 12. The percentage of women achieving the minimal clinically important difference (MCID) in the number of hot flashes on week 12 was determined. The efficacy substudy modified intent-to-treat population included 365 women (desvenlafaxine, n = 184; placebo, n = 181). Desvenlafaxine 100 mg/day significantly reduced the number and severity of hot flashes versus placebo on week 4 (P desvenlafaxine reduced the number of moderate and severe hot flashes by 7.3 (62%) per day (placebo, -4.5 [38%] per day) and the severity score by 0.59 (25%) per day (placebo, -0.28 [12%] per day). MCID-a reduction of 5.35 moderate and severe hot flashes per day-was achieved by 64% of desvenlafaxine-treated women (placebo, 41%; P desvenlafaxine and 3.7% (7/190) of participants taking placebo discontinued because of adverse events (P = 0.016), and 2.5% (5/200) of participants taking desvenlafaxine and 8.4% (16/190) of participants taking placebo discontinued because of lack of efficacy (P = 0.012). Postmenopausal women with moderate to severe hot flashes who are treated with desvenlafaxine achieve rapid symptom reduction that is clinically relevant based on MCID.

    Report the efficacious use of stellate ganglion blocks (SGBs) in treating the anxiety symptoms of four patients diagnosed with combat-related post-traumatic stress disorder (PTSD) and discuss possible mechanisms of action to explain these findings. Successful treatment of PTSD with SGB has been demonstrated and reported previously at Walter Reed Army Medical Center. An identical protocol was used at Tripler Army Medical Center to treat four service members diagnosed with combat-related PTSD. All patients reported received an SGB on the right side at the level of C6. The patient's PTSD symptoms were evaluated using the Post-traumatic Stress Disorder Checklist (PCL). This checklist was distributed one day before treatment and again the day following treatment. The patients were also given the PCL at subsequent follow-up visits to quantify sustained benefit. SGB showed acute benefit for the symptoms of PTSD by markedly reduced PCL scores after the procedure. Benefits were also sustained during close outpatient follow-up. Selective blockade of the right stellate ganglion at C6 is a minimally invasive procedure with an excellent safety profile that may provide sustained relief of PTSD symptoms. The procedure may also provide benefit for those who are resistant to psychotropic intervention. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

    Metacognitive training (MCT) is a new, widely used intervention for psychosis. The present meta-analysis examines the efficacy of MCT in schizophrenia. Fifteen studies comparing effects of MCT on positive symptoms, delusions or acceptance of MCT with a control group were included in this meta-analysis. These studies comprised a total of 408 patients in the MCT condition and 399 in the control condition. The moderating effects of masking of outcome assessment, randomization, incomplete outcome data, use of an active control intervention, and individual vs group MCT were investigated. Possible effects of sensitivity analyses and publication bias were also examined. The results show a significant overall effect of MCT for positive symptoms (g = -0.34, 95% CI [-0.53, -0.15]), delusions (g = -0.41, 95% CI [-0.74, -0.07]) and acceptance of the intervention (g = -0.84, 95% CI [-1.37, -0.31]). Using only studies being at low risk for bias regarding randomization, masking and incomplete outcome data reduced effect sizes for positive symptoms and delusions (g = -0.28, 95% CI [-0.50, -0.06] and g = -0.18, 95% CI [-0.43, 0.06]), respectively. This meta-analysis demonstrates that MCT exerts a small to moderate effect on delusions and positive symptoms and a large effect on acceptance of the intervention. The effect on delusions is reduced, but remains significant when potential biases are considered.

    To examine whether a cognitive-behavioral group program among pregnant women with elevated levels of anxiety or depression may reduce anxious and depressive symptoms and has a positive impact on risk factors for anxiety disorders and depression. A total of 753 participants were recruited. After completion of the clinical standardized interview, 160 participants were randomized to an intervention group or a control condition. Psychometric assessments took place at T1 (preintervention), T2 (antenatal follow-up), and T3 (3 months postpartum). Analyses included women who took part in all 3 assessments (intervention group, N = 21; control group, N = 53). The subjective program evaluation by the participants was highly positive, but with the exception of a short-term effect on the quality of an intimate partnership (F1/67 = 4.056; P anxiety or depressive symptoms were not found. However, there was an intervention effect 3 months postpartum for participants with high depressive symptoms at T1 (Edinburgh Postnatal Depression Scale score of ≥10) (F1/69 = 5.410; P women with rather low levels of anxiety and depression. For women with higher depressive symptoms during pregnancy, a cognitive-behavioral group program may have a positive impact on the course of depressive symptoms during the postpartum period.

    Introduction Cognitive behavioural therapy has been shown to improve depressive symptoms in adults with mild to moderate depression. To overcome many of the barriers associated with delivering this treatment, attempts have been made to deliver cognitive behavioural therapy via the Internet. The objective of this meta-analysis is to assess whether Internet-based cognitive behavioural therapy delivered to adults with depressive symptoms leads to a reduction in these symptoms as compared to those who receive no therapy. Methods In September 2015, the Cochrane, PubMed and PsycInfo databases were searched; studies were also found through bibliography searches. Studies were included if they were randomized controlled trials published in English between 2005-2015 conducted with adults >18 years of age experiencing mild to moderate depression where study subjects received Internet-based cognitive behavioural therapy, and the control group was placed on a wait-list. The search yielded 257 articles; 14 of these were included in the meta-analysis. Results Internet delivered cognitive behavioural therapy had a medium effect on reducing depressive symptoms at the end of the study period (standardized mean difference: 0.74, confidence interval: 0.62-0.86, p cognitive behavioural therapy also has a large sustained effect in maintaining reduction of depressive symptoms in follow-up measures done 3-6 months after the conclusion of the therapy (standardized mean difference: 0.83, confidence interval: 0.69-0.99, p Cognitive behavioural therapy delivered over the Internet leads to immediate and sustained reduction in depressive symptoms; thus, it may be a good treatment modality for individuals unable or unwilling to access traditional face-to-face therapy.

    To compare the success of an inferior alveolar nerve block (IANB) after injecting a combination of mepivacaine and tramadol or mepivacaine alone in patients with symptomatic irreversible pulpitis (SIP) in mandibular permanent molars. This study was a double-blind, randomized, controlled clinical trial. Two study groups were selected, each consisting of 28 patients who exhibited SIP on the first or second mandibular molars. All included patients presented with moderate-to-severe preoperative pain according to the modified Heft-Parker visual analogue scale (VAS). Patients were anaesthetized using the IANB technique employing identical cartridges that contained either 1.3 mL of 2% mepivacaine with epinephrine 1 : 100 000 plus 0.5 mL of tramadol 50 mg mL(-1) (experimental group) or 1.8 mL of 2% mepivacaine with epinephrine 1 : 100 000 (control group). After 15 min, anaesthesia was evaluated by a progressive four-test examination, that is numbness of the lip, positive or negative cold test, asymptomatic management of dental hard tissues and access to dental pulp. Success of the IANB was defined as the absence of pain during any of these evaluations. The data were analysed with a chi-square, Fisher's or Mann-Whitney U test. A total of 74 patients were initially assessed, with 56 patients eventually included and 18 excluded. No significant differences in age (P = 0.384) or gender (P = 1) were found between the two groups. The success rates of anaesthesia with the IANB for the experimental and control groups were 57.1 and 46.4%, respectively. The success rate of anaesthesia in the experimental group was not significantly different (P ˃ 0.05) from that of the control group. The duration of the anaesthetic effect was significantly longer for the experimental group (P = 0.026). The combination of mepivacaine-tramadol achieved similar success rates for IANB when compared to mepivacaine 2% epinephrine 1 : 100 000. There was no significant difference in the anaesthetic efficacy

    Full Text Available Rhinos® SR is a fixed combination of 5 mg loratadine and 60 mg pseudoephedrine immediate release and 60 mg pseudoephedrine sustained release. The present study was aimed to assess the efficacy of Rhinos® SR on nasal airway resistance (NAR objectively using rhinomanometer and on nasal symptoms in patients with perennial allergic rhinitis (PAR in a tropical country. This was a randomized, double-blind, parallel group study in 59 PAR patients who visited the ENT clinic at Dr. Soetomo General Hospital, Surabaya. Outpatients of both gender, having moderate to severe PAR for a minimal of 2 years, aged 12 years or older, with a total nasal symptom score (TNSS > 6 and a nasal congestion score > 2, received Rhinos® SR or placebo twice daily for 7 days. The primary efficacy parameter was the decrease in the NAR values (measured by rhinomanometer on Day 1 of Rhinos® SR from those of placebo. The NAR values were calculated as the area under the curve (AUC of NAR versus time. The secondary efficacy parameters were the percentage reduction of the clinical symptoms (nasal and nonnasal evaluated by both the patient and the physician after 1 week use of Rhinos® SR or placebo. From 59 eligible patients, all completed this 1-week trial. For NAR values, after the baseline were considered as 100%, the AUC0-10 h were not significantly different between Rhinos® SR and placebo. However, as the pseudoephedrine reached its peak concentration, i.e. 2 hrs for the immediate release and 6 hrs for the sustained release, then AUC0-2 h and AUC0-6 h of Rhinos® SR were significantly lower compared to those of placebo. Total nasal symptom score (TNSS evaluated by the patient (sum of the last 3 mornings for Rhinos® SR decreased 33.0% from baseline (p < 0.001, for placebo decreased 21.9% from baseline (p = 0.002, but the decrease by Rhinos® SR was not significantly different from the decrease by placebo.

    Acute bacterial respiratory infections (ABRIs) require treatment with antibiotics. Although antibiotics may address the underlying pathogenic factors, over-the-counter (OTC) agents can play an adjuvant role in relieving mucus-related symptoms. This complimentary role contributes to the healing process and is supported by current clinical guidelines.

    Full Text Available This review systematically assessed the clinical evidence for and against acupuncture as a treatment for psychological symptoms associated with opioid addiction. The database was accessed from MEDLINE and China Knowledge Resource Integrated Database. We included all randomized clinical trials published in Chinese and English regardless of their controls. Meta-analysis was performed using the RevMan software, version 5.2. We conducted a literature search of 16 databases from their inception to January 2014. Four studies from Western countries did not report any clinical gains in the treatment of psychological symptoms associated with opioid addiction. 10 of 12 studies from China have reported positive findings regarding the use of acupuncture to treat the psychological symptoms associated with opioid addiction. The methodological quality of the included studies was poor. The meta-analysis indicated that there was a significant difference between the treatment group and the control group for anxiety and depression associated with opioid addiction, although groups did not differ on opioid craving. This review and meta-analysis could not confirm that acupuncture was an effective treatment for psychological symptoms associated with opioid addiction. However, considering the potential of acupuncture demonstrated in the included studies, further rigorous randomized controlled trials with long followup are warranted.

    Although turmeric and its curcumin-enriched extracts have been used for treating arthritis, no systematic review and meta-analysis of randomized clinical trials (RCTs) have been conducted to evaluate the strength of the research. We systemically evaluated all RCTs of turmeric extracts and curcumin for treating arthritis symptoms to elucidate the efficacy of curcuma for alleviating the symptoms of arthritis. Literature searches were conducted using 12 electronic databases, including PubMed, Embase, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database. Search terms used were "turmeric," "curcuma," "curcumin," "arthritis," and "osteoarthritis." A pain visual analogue score (PVAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used for the major outcomes of arthritis. Initial searches yielded 29 articles, of which 8 met specific selection criteria. Three among the included RCTs reported reduction of PVAS (mean difference: -2.04 [-2.85, -1.24]) with turmeric/curcumin in comparison with placebo (P turmeric/curcumin treatment (mean difference: -15.36 [-26.9, -3.77]; P = .009). Furthermore, there was no significant mean difference in PVAS between turmeric/curcumin and pain medicine in meta-analysis of five studies. Eight RCTs included in the review exhibited low to moderate risk of bias. There was no publication bias in the meta-analysis. In conclusion, these RCTs provide scientific evidence that supports the efficacy of turmeric extract (about 1000 mg/day of curcumin) in the treatment of arthritis. However, the total number of RCTs included in the analysis, the total sample size, and the methodological quality of the primary studies were not sufficient to draw definitive conclusions. Thus, more rigorous and larger studies are needed to confirm the therapeutic efficacy of turmeric for arthritis.

    Previous work has demonstrated the efficacy and safety of fesoterodine in older and younger subjects with overactive bladder (OAB) symptoms. The effect of long-term fesoterodine treatment in different age groups has not been assessed. The aim was to determine the impact of age on the safety, tolerability and efficacy of long-term treatment with fesoterodine 8 mg in subjects with OAB syndrome. This was a pooled analysis of two identically designed open-label extensions of 12-week, randomized, double-blind, placebo-controlled studies. The setting was urology and general practice offices. Subjects who participated in the 12-week, double-blind studies and opted to continue long-term, open-label treatment with fesoterodine were included. Subjects were initiated on fesoterodine 8 mg/day at open-label baseline. After 1 month, subjects could elect dose reduction to 4 mg/day and subsequent re-escalation to 8 mg; each was permitted once annually. Maximal duration of open-label treatment ranged from 24 to 36 months. Discontinuations, subject-reported treatment tolerance, and efficacy (3-day diaries) were assessed at open-label baseline and months 1, 4, 8, 12 and 24. A total of 890 subjects were treated (age fesoterodine 8 mg throughout treatment; this rate was highest among subjects aged ≥75 years (age fesoterodine 8 mg at each visit after open-label baseline up to 36 months. No new or unexpected safety signals were observed in any age group. Most subjects reported 'good' or 'excellent' treatment tolerance throughout the study (age fesoterodine (administered primarily as 8 mg) was well tolerated and associated with sustained improvements in OAB symptoms, irrespective of age.

    As many as 10-15% of new mothers experience severe emotional distress frequently labelled postpartum depression (PPD) (Brockington, 2004; O’Hara & Swain, 1996). The consequences of postpartum depressive symptoms can be serious for the mother, her child and family. Indeed, women who suffer from PPD are less capable of carrying out maternal duties, which may influence the child’s cognitive, and socioemotional development (Goodman, Brogan, Lynch & Shielding, 1993), as well as the infant’s attach...

    The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 2% lidocaine with 1:100,000 epinephrine and 3% mepivacaine in the maxillary high tuberosity second division nerve block. Fifty subjects randomly received maxillary high tuberosity second division nerve blocks by using 3.6 mL of 2% lidocaine with 1:100,000 epinephrine and 3.6 mL of 3% mepivacaine at 2 separate appointments spaced at least 1 week apart. The anterior, premolar, and molar teeth were pulp tested in 4-minute cycles for a total of 60 minutes. Success was defined as no subject response to 2 consecutive 80 readings with the electric pulp tester. The high tuberosity approach to the maxillary second division nerve block with both anesthetic formulations resulted in a high success rate (92%-98%) for the first and second molars. Approximately 76%-78% of the second premolars were anesthetized with both anesthetic formulations. Both anesthetic formulations were ineffective for the anterior teeth and first premolars. The use of 3% mepivacaine provided a significantly shorter duration of pulpal anesthesia than 2% lidocaine with 1:100,000 epinephrine in the molars and premolars.

    The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 2% lidocaine with 1:100,000 epinephrine, 2% lidocaine with 1:50,000 epinephrine, and 3% mepivacaine in the intraoral, infraorbital nerve block. Forty subjects randomly received intraoral, infraorbital nerve blocks by using a cartridge of 2% lidocaine with 1:100,000 or 1:50,000 epinephrine and a cartridge of 3% mepivacaine at 3 separate appointments spaced at least 1 week apart. The anteriors, premolars, and first molar were pulp tested in 4-minute cycles for a total of 60 minutes. The intraoral, infraorbital nerve block was ineffective in providing profound pulpal anesthesia of the maxillary central incisor, lateral incisor, and first molar. Successful pulpal anesthesia of the canine and first and second premolars ranged from 75%-92% by using 2% lidocaine with 1:100,000 and 1:50,000 epinephrine. However, pulpal anesthesia did not last for 60 minutes. The use of 3% mepivacaine provided a shorter duration of anesthesia than the lidocaine formulations with epinephrine in the canines and premolars.

  7. Ulnar nerve stimulation at the palm in diagnosing distal ulnar nerve entrapment.

    2005-01-01

    Distal entrapment of the ulnar nerve at the wrist and hand (Guyon's syndrome) is a relatively uncommon condition. It may present with a confusing permutation of sensory and motor symptoms, depending on which branches of the ulnar nerve are involved Electrodiagnostic test procedures are often helpful in sorting out this quandary. Electrophysiologic studies that include electrical stimulation of the nerve at the palm, in addition to stimulation of the ulnar nerve at other locations, are useful in demonstrating the focal nerve conduction abnormality that is involved in the entrapment. Sensory and motor recordings from palmar stimulation of the ulnar nerve are not technically difficult procedures, and can be performed routinely.

    Cerebral malaria is the most severe complication of Plasmodium falciparum infection, and a leading cause of death in children under the age of five in malaria-endemic areas. We report high therapeutic efficacy of a novel formulation of liposome-encapsulated water-soluble glucocorticoid prodrugs, and in particular β-methasone hemisuccinate (BMS), for treatment of experimental cerebral malaria (ECM), using the murine P. berghei ANKA model. BMS is a novel derivative of the potent steroid β-methasone, and was specially synthesized to enable remote loading into nano-sterically stabilized liposomes (nSSL), to form nSSL-BMS. The novel nano-drug, composed of nSSL remote loaded with BMS, dramatically improves drug efficacy and abolishes the high toxicity seen upon administration of free BMS. nSSL-BMS reduces ECM rates in a dose-dependent manner and creates a survival time-window, enabling administration of an antiplasmodial drug, such as artemisone. Administration of artemisone after treatment with the nSSL-BMS results in complete cure. Treatment with BMS leads to lower levels of cerebral inflammation, demonstrated by changes in cytokines, chemokines, and cell markers, as well as diminished hemorrhage and edema, correlating with reduced clinical score. Administration of the liposomal formulation results in accumulation of BMS in the brains of sick mice but not of healthy mice. This steroidal nano-drug effectively eliminates the adverse effects of the cerebral syndrome even when the treatment is started at late stages of disease, in which disruption of the blood-brain barrier has occurred and mice show clear signs of neurological impairment. Overall, sequential treatment with nSSL-BMS and artemisone may be an efficacious and well-tolerated therapy for prevention of CM, elimination of parasites, and prevention of long-term cognitive damage.

    Full Text Available We performed a meta-analysis to compare treatment with a combination of solifenacin plus tamsulosin oral controlled absorption system (TOCAS with placebo or TOCAS monotherapy. The aim of the meta-analysis was to clarify the efficacy and safety of the combination treatments method for lower urinary tract symptoms (LUTS. We searched for trials of men with LUTS that were randomized to combination treatment compared with TOCAS monotherapy or placebo. We pooled data from three placebo-controlled trials meeting inclusion criteria. Primary outcomes of interest included changes in International Prostate Symptom Score (IPSS and urinary frequency. We also assessed postvoid residual, maximum urinary flow rate, incidence of urinary retention (UR, adverse events. Data were pooled using random or fixed effect models for continuous outcomes and the Mantel-Haenszel method to generate risk ratio. Reductions in IPSS storage subscore and total urgency and frequency score (TUFS were observed with solifenacin 6 mg plus TOCAS compared with placebo (P< 0.0001 and P< 0.0001, respectively. Reductions in IPSS storage subscore and TUFS were observed with solifenacin 9 mg plus TOCAS compared with placebo (P = 0.003 and P= 0.0006, respectively. Reductions in TUFS was observed with solifenacin 6 mg plus TOCAS compared with TOCAS (P = 0.01. Both combination treatments were well tolerated, with low incidence of UR. Solifenacin 6 mg plus TOCAS significantly improved total IPSS, storage and voiding symptoms compared with placebo. Solifenacin 6 mg plus TOCAS also improved storage symptoms compared with TOCAS alone. There was no additional benefit of solifenacin 9 mg compared with 6 mg when used in combination with TOCAS.

    To evaluate success of pulpal anaesthesia of mandibular 1st molar by using 4% articaine in buccal infiltration versus 2% lidocaine in inferior alveolar nerve block. Randomized control trial. Department of Operative Dentistry, Sardar Begum Dental College, Gandhara University, Peshawar, from March to August 2014. One hundred and fifty-six emergency patients, who had 1st molar diagnosed with irreversible pulpitis, participated in the study. Subjects were divided into two groups by random allocation. One group received 4% articaine buccal infiltration and the other group received inferior alveolar nerve block of 2% lidocaine. Subjects’self-reported pain response was recorded on Heft Parker Visual Analogue Scale after local anaesthetic administration during access cavity preparation and pulp extirpation. Mean age of subjects was 31.46 ±10.994 years. The success rate of 4% buccal infiltration was 76.9%; whereas the success rate of 2% lidocaine inferior alveolar nerve block was 62.8%. There was no statistically significant difference between the two groups. 4% articaine buccal infiltration can be considered a viable alternative to 2% lidocaine inferior alveolar nerve block in securing successful pulpal anaesthesia for endodontic therapy.

    OBJECTIVE: To analyze the distribution characteristics of cardiac autonomic nerves and to explore the correlation between cardiac autonomic nerve distribution and arrhythmia.DATA RETRIEVAL: A computer-based retrieval was performed for papers examining the distribution of cardiac autonomic nerves, using "heart, autonomic nerve, sympathetic nerve, vagus nerve, nerve distribution, rhythm and atrial fibrillation" as the key words.SELECTION CRITERIA: A total of 165 studies examining the distribution of cardiac autonomic nerve were screened, and 46 of them were eventually included.MAIN OUTCOME MEASURES: The distribution and characteristics of cardiac autonomic nerves were observed, and immunohistochemical staining was applied to determine the levels of tyrosine hydroxylase and acetylcholine transferase (main markers of cardiac autonomic nerve distribution). In addition, the correlation between cardiac autonomic nerve distribution and cardiac arrhythmia was investigated.RESULTS: Cardiac autonomic nerves were reported to exhibit a disordered distribution in different sites, mainly at the surface of the cardiac atrium and pulmonary vein, forming a ganglia plexus. The distribution of the pulmonary vein autonomic nerve was prominent at the proximal end rather than the distal end, at the upper left rather than the lower right, at the epicardial membrane rather than the endocardial membrane, at the left atrium rather than the right atrium, and at the posterior wall rather than the anterior wall. The main markers used for cardiac autonomic nerves were tyrosine hydroxylase and acetylcholine transferase. Protein gene product 9.5 was used to label the immunoreactive nerve distribution, and the distribution density of autonomic nerves was determined using a computer-aided morphometric analysis system.CONCLUSION: The uneven distribution of the cardiac autonomic nerves is the leading cause of the occurrence of arrhythmia, and the cardiac autonomic nerves play an important role in the

After receiving the device, some patients fear that it will malfunction, or they remain in a constant state of tension due to sudden electrical discharges and develop symptoms of anxiety and depression. A search with the key words “anxiety”, “depression”, “implantable cardioverter”, “cognitive behavioral therapy” and “psychotherapy” was carried out. The search was conducted in early January 2013. Sources for the search were ISI Web of Knowledge, PubMed, and PsycINFO. A total of 224 articles were retrieved: 155 from PubMed, 69 from ISI Web of Knowledge. Of these, 16 were written in a foreign language and 47 were duplicates, leaving 161 references for analysis of the abstracts. A total of 19 articles were eliminated after analysis of the abstracts, 13 were eliminated after full-text reading, and 11 articles were selected for the review. The collection of articles for literature review covered studies conducted over a period of 13 years (1998-2011, and, according to methodological design, there were 1 cross-sectional study, 1 prospective observational study, 2 clinical trials, 4 case-control studies, and 3 case studies. The criterion used for selection of the 11 articles was the effectiveness of the intervention of CBT to decrease anxiety and depression in patients with ICD, expressed as a ratio. The research indicated that CBT has been effective in the treatment of ICD patients with depressive and anxiety symptoms. Research also showed that young women represented a risk group, for which further study is needed. Because the number of references on this theme was small, further studies should be carried out.

Sources for the search were ISI Web of Knowledge, PubMed, and PsycINFO. A total of 224 articles were retrieved: 155 from PubMed, 69 from ISI Web of Knowledge. Of these, 16 were written in a foreign language and 47 were duplicates, leaving 161 references for analysis of the abstracts. A total of 19 articles were eliminated after analysis of the abstracts, 13 were eliminated after full-text reading, and 11 articles were selected for the review. The collection of articles for literature review covered studies conducted over a period of 13 years (1998-2011), and, according to methodological design, there were 1 cross-sectional study, 1 prospective observational study, 2 clinical trials, 4 case-control studies, and 3 case studies. The criterion used for selection of the 11 articles was the effectiveness of the intervention of CBT to decrease anxiety and depression in patients with ICD, expressed as a ratio. The research indicated that CBT has been effective in the treatment of ICD patients with depressive and anxiety symptoms. Research also showed that young women represented a risk group, for which further study is needed. Because the number of references on this theme was small, further studies should be carried out.

    Improved treatment of alcohol dependence is a high priority, including defining subtypes that might respond differently. We evaluated a medication combination of intravenous flumazenil (FMZ) and oral gabapentin (GBP) in alcoholics who did and did not exhibit pretreatment alcohol withdrawal (AW) symptoms. Sixty alcohol-dependent individuals (44 with low AW and 16 with high AW) were randomized to receive FMZ (2 mg of incremental bolus for 20 minutes for 2 consecutive days) and GBP (up to 1200 mg nightly for 39 days) or their inactive placebos. Alcohol withdrawal was measured for the first 2 days, and drinking, sleep parameters, and adverse events were monitored during weekly evaluations, along with behavioral counseling sessions. Percent days abstinent (PDA) during treatment and time to first heavy drinking (TFHD) day were primary outcome variables. There was an interaction between the pretreatment AW status and the medication group on PDA (P = 0.0006) and TFHD (P = 0.06). Those in the high AW group had more PDA and more TFHD if treated with active medications, whereas those in the low AW group had more PDA and more TFHD if treated with placebo. This interaction remained for those totally abstinent (P = 0.03) and was confirmed by percent carbohydrate-deficient transferrin values. In addition, the pattern of response remained up to 8 weeks after treatment. In addition, in those with high AW, greater improvement in AW symptoms was observed in the active medication group compared with the placebo group. These results suggest a differential response to FMZ/GBP treatment, depending on pretreatment AW status that should be taken into account during future treatment trials.

    The rapid advances and adoption of smartphone technology presents a novel opportunity for delivering mental health interventions on a population scale. Despite multi‐sector investment along with wide‐scale advertising and availability to the general population, the evidence supporting the use of smartphone apps in the treatment of depression has not been empirically evaluated. Thus, we conducted the first meta‐analysis of smartphone apps for depressive symptoms. An electronic database search in May 2017 identified 18 eligible randomized controlled trials of 22 smartphone apps, with outcome data from 3,414 participants. Depressive symptoms were reduced significantly more from smartphone apps than control conditions (g=0.38, 95% CI: 0.24‐0.52, pSmartphone interventions had a moderate positive effect in comparison to inactive controls (g=0.56, 95% CI: 0.38‐0.74), but only a small effect in comparison to active control conditions (g=0.22, 95% CI: 0.10‐0.33). Effects from smartphone‐only interventions were greater than from interventions which incorporated other human/computerized aspects along the smartphone component, although the difference was not statistically significant. The studies of cognitive training apps had a significantly smaller effect size on depression outcomes (p=0.004) than those of apps focusing on mental health. The use of mood monitoring softwares, or interventions based on cognitive behavioral therapy, or apps incorporating aspects of mindfulness training, did not affect significantly study effect sizes. Overall, these results indicate that smartphone devices are a promising self‐management tool for depression. Future research should aim to distil which aspects of these technologies produce beneficial effects, and for which populations. PMID:28941113

    The objectives of this study were to identify signs of vestibular nerve suffering through a bedside vestibular examination protocol in case of sudden sensorineural unilateral hearing loss without spontaneous signs of vestibular impairment and to propose a bed-side vestibular examination based protocol for the focused execution of gadolinium-enhanced magnetic resonance imaging (MRI) only if a vestibular schwannoma is suspected. 96 patients, 52 men, 44 women, mean age 57.73 +/- 12.85 years, suffering from sudden sensorineural unilateral hearing loss, which presented neither vertigo nor spontaneous nystagmus, were enrolled. Pure tone audiometry, tympanometry, measurement of acoustic reflexes and Anderson test to detect adaptation, bedside vestibular examination through head shaking test, vibration test, head impulse test, hyperventilation test and detection of nystagmus in supine and lateral decubitus to search for signs of vestibular impairment were performed. Patients with signs of vestibular impairment and pure tone audiometry threshold at high frequencies better than 70 dB nHL were subjected to auditory brainstem responses. Gadolinium enhanced MRI centred on internal acoustic canals was carried out in all patients with sudden sensorineural unilateral hearing loss. Main outcome measures were signs of vestibular impairment at vestibular bedside examination and presence of vestibular schwannoma on MRI. Signs of vestibular impairment were detected in 22/96 cases (22.9%); a vestibular schwannoma was detected by MRI in 5/96 cases (5.2%), always when vestibular impairment was present. In case of sudden sensorineural unilateral hearing loss, vestibular bedside examination seems to be useful to restrict the suspicion of a vestibular schwannoma to cases with signs of vestibular impairment, reducing the number of MRI exams, with considerable economic savings. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    While assessing the methylphosphonothioic acid S-(2-(bis(1-methylethyl)amino)ethyl)O-ethyl ester (VX) induced respiratory toxicity and evaluating therapeutics against lung injury, we observed that the animals were experiencing abnormal swelling in the abdominal area. Nerve agent has been known to increase salivary, nasal and gastrointestinal secretion and cause diarrhea. This study was initiated to investigate the effect of VX on the gastrointestinal tract (GI) since abdominal pathology may affect breathing and contribute to the on going respiratory toxicity. The mid-abdominal diameter and the size of the lower left abdomen was measured before and after 27.3 mg/m3 VX exposure by microinstillation and at 30 min intervals up to 2 h post-VX exposure. Both VX and saline exposed animals exhibited a decrease in circumference of the upper abdomen, although the decrease was slightly higher in VX-exposed animals up to 1 h. The waist diameter increased slightly in VX-exposed animals from 60 to 90 min post-VX exposure but was similar to saline controls. The lower left abdomen near to the cecum, 6 cm below and 2cm to the right of the end of the sternum, showed an increase in size at 30-60 min that was significantly increased at 90-120 min post-VX exposure. In addition, VX-exposed animals showed loose fecal matter compared to controls. Necropsy at 24h showed an increased small intestine twisting motility in VX-exposed animals. Body tissue AChE assay showed high inhibition in the esophagus and intestine in VX-exposed animals indicating that a significant amount of the agent is localized to the GI following microinstillation exposure. These results suggest that microinstillatipn inhalation VX exposure induces gastrointestinal disturbances similar to that of irritable bowel syndrome and bloating.

    Background Significant anxiety symptoms are associated with poor clinical course and outcome in major depressive disorder (MDD). This single-arm, open-label study aimed to evaluate the efficacy and tolerability of escitalopram treatment in patients with MDD and anxiety symptoms. Methods Adult patients with MDD and anxiety symptoms (Montgomery–Asberg Depression Rating Scale [MADRS] ≥22 and Hamilton Anxiety Rating Scale [HAM-A] ≥14) were enrolled and received escitalopram (10–20 mg/day) treatment for 24 weeks. Symptom status was assessed by MADRS, 17-item-Hamilton Depression Rating Scale, HAM-A, and Clinical Global Impression Scale at baseline and the following visits. Quality of life was assessed by Short Form-12, and safety was evaluated by adverse events, laboratory investigations, vital signs, and physical findings. Results Overall, 200 of 318 (66.2%) enrolled patients completed the 24-week treatment. The remission (MADRS ≤10 and HAM-A ≤7) rate in the full analysis set (N=285) was 73.3% (95% confidence interval: 67.80, 78.38) at week 24. Mean (± standard deviation) MADRS total score was 33.4 (±7.13) and HAM-A score was 27.6 (±7.26) at baseline, which reduced to 6.6 (±10.18) and 6.0 (±8.39), respectively, at week 24. Patients with higher baseline depression and anxiety level took longer to achieve similar remission rates. Overall, 80 of the 302 (26.5%) patients included in the safety set reported at least 1 treatment-emergent adverse event (TEAE). Most frequently reported TEAEs (>2%) were headache (4.0%), nasopharyngitis (3.6%), nausea (3.0%), and dizziness (2.6%). Serious TEAEs were reported by 1.3% patients; no deaths were reported. Conclusion Escitalopram 10–20 mg/day was effective and well-tolerated in the long-term treatment of MDD with anxiety symptoms in adult Chinese population. PMID:28255239

    The study tested the model of adaptation after trauma by Benight and Bandura (2004) indicating that posttraumatic recovery may be predicted directly by coping self-efficacy (CSE) and indirectly by social support. These relations were investigated in the context of posttraumatic growth (PTG) among Hurricane Katrina survivors living with HIV. Additionally, it was hypothesized that among individuals with more intensive Posttraumatic Stress Disorder (PTSD) symptoms, those with strong CSE would experience the strongest PTG. Cross-sectional data were collected among 90 patients with HIV who reinitiated care at the HIV outpatient clinic. Questionnaires were administered approximately 14 months after the hurricane. Higher CSE was related to higher PTG among the survivors who suffered from more intensive PTSD symptoms. Received social support was directly related to only one index of PTG, relating to others. Furthermore, although there was a significant relationship between social support and CSE, the indirect conditional effect of received social support on PTG was not confirmed. Similar results were obtained across the indices of PTG, controlling for the level of exposure to hurricane-related trauma. Cross-sectional design and convenience character of the sample warrants replications.

We also evaluated the effect of the PUA on the treatment efficacy of tamsulosin on men with LUTS.Materials and methods: The records were obtained from a prospective database for first-visit male patients with LUTS in the outpatient department of our institution. These patients underwent a detailed physical examination and taking of medical history. A transrectal ultrasound was performed on these patients. The prostate size, length of intravesical prostatic protrusion (IPP, PUA, and International Prostate Symptom Score (IPSS of the patients were evaluated. Uroflowmetry and a bladder scan for residual urine were also performed on every patient. Tamsulosin 0.2 mg per day was prescribed. The IPSS and uroflowmetry were reevaluated after they had received treatment for 3 months.Results: A total of 178 patients were included, and 149 of them completed this cohort study. The mean PUA was 48.32°±13.74°. The mean prostate volume was 39.19±20.87 mL, and the mean IPP was 5.67±7.85 mm. On multivariate linear regression analysis, the PUA was independently associated with the IPSS (P<0.001, Qmax (P=0.004, post-treatment IPSS change (P=0.032, and post-treatment Qmax change (P<0.001. However, the prostate volume and IPP were not associated with these clinical items.Conclusion: The PUA is significantly associated with Qmax and IPSS in men with LUTS. The PUA is also inversely correlated with changes in Qmax and IPSS after tamsulosin treatment. Namely, the PUA might be a

    Full Text Available Despite the capacity of Schwann cells to support peripheral nerve regeneration, functional recovery after nerve injuries is frequently poor, especially for proximal injuries that require regenerating axons to grow over long distances to reinnervate distal targets. Nerve transfers, where small fascicles from an adjacent intact nerve are coapted to the nerve stump of a nearby denervated muscle, allow for functional return but at the expense of reduced numbers of innervating nerves. A 1-hour period of 20 Hz electrical nerve stimulation via electrodes proximal to an injury site accelerates axon outgrowth to hasten target reinnervation in rats and humans, even after delayed surgery. A novel strategy of enticing donor axons from an otherwise intact nerve to grow through small nerve grafts (cross-bridges into a denervated nerve stump, promotes improved axon regeneration after delayed nerve repair. The efficacy of this technique has been demonstrated in a rat model and is now in clinical use in patients undergoing cross-face nerve grafting for facial paralysis. In conclusion, brief electrical stimulation, combined with the surgical technique of promoting the regeneration of some donor axons to ′protect′ chronically denervated Schwann cells, improves nerve regeneration and, in turn, functional outcomes in the management of peripheral nerve injuries.

    Anxiety and depression are common following traumatic brain injury (TBI), often co-occurring. This study evaluated the efficacy of a 9-week cognitive behavioral therapy (CBT) program in reducing anxiety and depression and whether a three-session motivational interviewing (MI) preparatory intervention increased treatment response. A randomized parallel three-group design was employed. Following diagnosis of anxiety and/or depression using the Structured Clinical Interview for DSM-IV, 75 participants with mild-severe TBI (mean age 42.2 years, mean post-traumatic amnesia 22 days) were randomly assigned to an Adapted CBT group: (1) MI + CBT (n = 26), or (2) non-directive counseling (NDC) + CBT (n = 26); or a (3) waitlist control (WC, n = 23) group. Groups did not differ in baseline demographics, injury severity, anxiety or depression. MI and CBT interventions were guided by manuals adapted for individuals with TBI. Three CBT booster sessions were provided at week 21 to intervention groups. Using intention-to-treat analyses, random-effects regressions controlling for baseline scores revealed that Adapted CBT groups (MI + CBT and NDC + CBT) showed significantly greater reduction in anxiety on the Hospital Anxiety and Depression Scale [95% confidence interval (CI) -2.07 to -0.06] and depression on the Depression Anxiety and Stress Scale (95% CI -5.61 to -0.12) (primary outcomes), and greater gains in psychosocial functioning on Sydney Psychosocial Reintegration Scale (95% CI 0.04-3.69) (secondary outcome) over 30 weeks post-baseline relative to WC. The group receiving MI + CBT did not show greater gains than the group receiving NDC + CBT. Findings suggest that modified CBT with booster sessions over extended periods may alleviate anxiety and depression following TBI.

    Full Text Available Abstract Introduction We report the case of a patient with Churg-Strauss syndrome with eighth cranial nerve palsy. Vestibulocochlear nerve palsy is extremely rare in Churg-Strauss syndrome. To the best of our knowledge, only one case of complicated neuropathy of the eighth cranial nerve has been described in a previous report presenting an aggregate calculation, but no differentiation between polyarteritis nodosa and Churg-Strauss syndrome was made. High-dose immunoglobulin was administered to our patient, and her neuropathy of the eighth cranial nerve showed improvement. Case presentation At the age of 46, a Japanese woman developed Churg-Strauss syndrome that later became stable with low-dose prednisolone treatment. At the age of 52, she developed sudden difficulty of hearing in her left ear, persistent severe rotary vertigo, and mononeuritis multiplex. At admission, bilateral perceptive deafness of about 80dB and eosinophilia of 4123/μL in peripheral blood were found. A diagnosis of cranial neuropathy of the eighth cranial nerve associated with exacerbated Churg-Strauss syndrome was made. Although high doses of steroid therapy alleviated the inflammatory symptoms and markers, the vertigo and bilateral hearing loss remained. Addition of a high-dose immunoglobulin finally resulted in marked alleviation of the symptoms associated with neuropathy of the eighth cranial nerve. Conclusions A high dose of immunoglobulin therapy shows favorable effects in neuropathy of the eighth cranial nerve, but no reports regarding its efficacy in cranial neuropathy have been published.

    We evaluated the efficacy and robustness of a second generation implantable stimulator for correcting drop foot (DF) in a patient with left-sided hemiplegia over 20 years of functional electrical stimulation (FES) of the common peroneal nerve (CPN). Dorsal flexion and eversion of the affected foot was partially restored by FES of the superficial region of the CPN innervating mostly the tibialis anterior (TA) and partly peroneus longus (PL) and peroneus brevis (PB) muscles. The reasons for implant failure during the long-term follow-up assessment were analyzed and resolving procedures were identified. The stimulator had an average failure rate of once every three years, due to repetitive mechanical load on the lead wires of its internal and/or external unit, and had to be serviced once per year to replace the heel switch integrated into the shoe sole. FES-associated mechanical trauma to the CPN elicited a thickening of the connective tissue around the CPN and a slightly compromised conduction velocity of the CPN. FES of the CPN, with the second generation implantable stimulator, improved gait parameters of the affected leg during the 20 years period. Long-term, daily FES enables a functional and reliable recruitment of nerve fibers, thus providing a sufficient dorsal flexion and optimal eversion of the affected foot to sustain unassisted, almost normal gait. Therefore, the presented implant is suitable for very long-term FES of the CPN. Copyright © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

    The diagnosis of cerebral venous sinus thrombosis still remains a real challenge. Seizure, unusual headache with sudden onset, unexplained persistently unilateral vascular headache and neurologic deficit-which is difficult to be attributed to a vascular territory are some of the suggestive symptoms. An isolated sixth nerve palsy is discussed as a rare presentation for cerebral venous thrombosis. Following the extensive investigation to rule out other possible diagnoses, magnetic resonance venogram revealed the final etiology of sixth nerve palsy that was ipsilateral left transverse sinus thrombosis; therefore, anticoagulant treatment with low molecular weight heparin was administered. Rapid and accurate diagnosis and treatment cause to achieve excellent outcomes for most patients. Considering different clinical features, risk factors and high index of suspicion are helpful to reach the diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Hemicrania continua (HC) is an uncommon primary headache disorder in which the diagnosis centers on unilaterality and its absolute responsiveness to indomethacin. We describe 3 patients with a long standing history of headache diagnosed as hemicrania continua. There was profound response to indomethacin which was limited by side effects. In one patient the therapy with indomethacin was limited secondary to co-morbidities. Initial diagnostic blockade provided significant relief of symptoms based on which radio-frequency ablation of the supraorbital nerve was performed with substantial improvement in symptoms. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. Radio-frequency ablation (RFA) has been reported in the literature for multiple indications. This case series is unique in that it describes 3 patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution, who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. This report is unique in that it describes three patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. After the RFA medical management was minimal to none in both patients. Though the utility and cost efficacy of RFA of peripheral nerves needs to be confirmed in well-designed trials we present these cases as an example of how this minimally invasive technique can safely provide analgesia in a difficult to treat cephalgia. Moreover if precise anatomical localization of the headache is possible then diagnostic blockade of the appropriate peripheral nerve may be performed followed by

    Background The primary objectives of the treatment for the lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) are to produce rapid, sustained, and safe improvements in the symptoms that affect the quality of life in the majority of men over 50. In this study, we evaluated the efficacy and safety of the combined therapy with terazosin (α1-adrenergic receptor antagonist) and tolterodine (anticholinergic agent) for LUTS associated with BPH.Methods This combination study included 69 patients diagnosed with LUTS associated with BPH based on the International Prostate Symptom Scores (IPSS), urinary flow rate, prostate volume, urinary residual, and their serum prostate-specific antigen levels. Initially, 191 patients were treated with terazosin 2 mg once daily for one week. Those patients with continued LUTS after the initial treatment were allocated randomly into two groups: terazosin group (n=36)in which patients were treated with terazosin 2 mg once daily for six weeks, and combination group (n=33) in which patients were treated with both terazosin 2 mg once daily and tolterodine 2 mg twice daily for 6 weeks.Results The IPSS were significantly improved in both groups after treatment, and the reduction of IPSS in the combination group was significantly greater than that in the terazosin group (P<0.01). A decrease in urgency, frequency and nocturia were the main contributory factors causing the reduction of IPSS in the combination group. The differences about the peak urinary flow rate and the residual urine from the baseline values were noted in both groups after treatment,but were not significant between the two groups. The incidence of adverse effects in the combination group was higher than that in the terazosin group. As expected the most common adverse effect was mouth dryness which was associated with anticholinergic drugs such as tolterodine.Conclusions Patients with LUTS associated BPH appear the improved IPSS after

    The objective of the study was to assess the efficacy and safety of desvenlafaxine (administered as desvenlafaxine succinate) for the treatment of vasomotor symptoms. This was a 26 week, double-blind, placebo-controlled trial of 567 postmenopausal women (mean age, 53.7 years; time since natural menopause, 4.8 years) experiencing 50 or more hot flushes (HFs) per week, randomly assigned to desvenlafaxine (100 or 150 mg) or placebo. Change from baseline in average daily number of moderate to severe HFs and average daily HF severity were compared with placebo at weeks 4, 12, and 26. A significantly greater decrease from baseline in number of HFs occurred at weeks 4 and 12 with 100 and 150 mg desvenlafaxine compared with placebo (week 12 reductions: 60%, 66%, and 47%, respectively; all P desvenlafaxine compared with placebo (all P desvenlafaxine-treated subjects than placebo-treated subjects discontinued because of adverse events during week 1 only. Desvenlafaxine is an effective treatment for menopausal HFs.

    Two hundred and 91 patients showing signs and symptoms of bacterial vaginosis (BV) were randomized to receive topical treatment with Fitostimoline (vaginal cream and vaginal ovules + vaginal washing) or benzydamine hydrochloride (vaginal cream + vaginal washing) for 7 days. Signs (leucorrhoea, erythema, oedema, and erosion) and symptoms (burning, pain, itching, vaginal dryness, dyspareunia, and dysuria) (scored 0-3) were evaluated at baseline and at the end of treatment; the total symptoms score (TSS) was also calculated. In 125 patients, a bacterial vaginosis was confirmed by vaginal swab test. The primary efficacy variable analysis, that is, the percentage of patients with therapeutic success (almost complete disappearance of signs and symptoms), demonstrated that Fitostimoline ovules and vaginal cream were therapeutically equivalent and that pooled Fitostimoline treatment was not inferior to benzydamine hydrochloride. All the treatments were well tolerated, with only minor local adverse events infrequently reported. The results of this study confirmed that gynaecological Fitostimoline is a safe and effective topical treatment for BV.

    A post hoc analysis evaluated the effects of levomilnacipran ER on individual symptoms and symptom domains in adults with major depressive disorder (MDD). Data were pooled from 5 Phase III trials comprising 2598 patients. Effects on depression symptoms were analyzed based on change from baseline in individual Montgomery-Åsberg Depression Rating Scale (MADRS) item scores. A1dditional evaluations included resolution of individual symptoms (defined as a MADRS item score ≤1 at end of treatment) and concurrent resolution of all 10 MADRS items, all MADRS6 subscale items, and all items included in different symptom clusters (Dysphoria, Retardation, Vegetative Symptoms, Anhedonia). Significantly greater mean improvements were found on all MADRS items except Reduced Appetite with levomilnacipran ER treatment compared with placebo. Resolution of individual symptoms occurred more frequently with levomilnacipran ER than placebo for each MADRS item (all Pdepression symptoms and symptom domains.

    Inhibition of acetylcholinesterase (AChE) after nerve agent exposure induces status epilepticus (SE), which causes brain damage or death. The development of countermeasures appropriate for the pediatric population requires testing of anticonvulsant treatments in immature animals. In the present study, exposure of 21-day-old (P21) rats to different doses of soman, followed by probit analysis, produced an LD{sub 50} of 62 μg/kg. The onset of behaviorally-observed SE was accompanied by a dramatic decrease in brain AChE activity; rats who did not develop SE had significantly less reduction of AChE activity in the basolateral amygdala than rats who developed SE. Atropine sulfate (ATS) at 2 mg/kg, administered 20 min after soman exposure (1.2 × LD{sub 50}), terminated seizures. ATS at 0.5 mg/kg, given along with an oxime within 1 min after exposure, allowed testing of anticonvulsants at delayed time-points. The AMPA/GluK1 receptor antagonist LY293558, or the specific GluK1 antagonist UBP302, administered 1 h post-exposure, terminated SE. There were no degenerating neurons in soman-exposed P21 rats, but both the amygdala and the hippocampus were smaller than in control rats at 30 and 90 days post-exposure; this pathology was not present in rats treated with LY293558. Behavioral deficits present at 30 days post-exposure, were also prevented by LY293558 treatment. Thus, in immature animals, a single injection of atropine is sufficient to halt nerve agent-induced seizures, if administered timely. Testing anticonvulsants at delayed time-points requires early administration of ATS at a low dose, sufficient to counteract only peripheral toxicity. LY293558 administered 1 h post-exposure, prevents brain pathology and behavioral deficits. - Highlights: • The LD{sub 50} of soman was determined in postnatal-day-21 rats. • Rats with no seizures after 1.2XLD{sub 50} soman had less reduction of AChE in the amygdala. • Atropine sulfate (ATS) at 2 mg/kg, given at 20 min after

    Background In order to simplify the complicated procedure of nerve-sparing radical hysterectomy, a novel technique characterized by integral preservation of the autonomic nerve plane has been employed for invasive cervical cancer. The objective of this study was to introduce the nerve plane-sparing radical hysterectomy technique and compare its efficacy and safety with that of nerve-sparing radical hysterectomy.Methods From September 2006 to August 2010, 73 consecutive patients with International Federation of Gynecology and Obstetrics stage IB to IIA cervical cancer underwent radical hysterectomy with two different nerve-sparing approaches. Nerve-sparing radical hysterectomy was performed for the first 16 patients (nerve-sparing radical hysterectomy group). The detailed autonomic nerve structures were identified and separated by meticulous dissection during this procedure. After January 2008, the nerve plane-sparing radical hysterectomy procedure was developed and performed for the next 57 patients (nerve plane-sparing radical hysterectomy group). During this modified procedure, the nerve plane (meso-ureter and its extension) containing most of the autonomic nerve structures was integrally preserved. The patients' clinicopathologic characteristics, surgical parameters, and outcomes of postoperative bladder function were compared between the two groups.Conclusion Nerve plane-sparing radical hysterectomy Is a reproducible and simplified modification of nerve-sparing radical hysterectomy, and may be preferable to nerve-sparing radical hysterectomy for treatment of early-stage invasive cervical cancer.

  12. An effect of wrapping peripheral nerve anastomosis with pedicled muscle flap on nerve regeneration in experiment

    Full Text Available Despite intrinsic capacity of peripheral nerves to regenerate, functional outcomes of peripheral nerves injury remain poor. Nerve ischemia, intra-/perineurial fibrosis and neuroma formation contribute a lot to that. Several authors demonstrated beneficial effects of increased vascularization at the site of injury on peripheral nerves regeneration. The use of highly vascularized autologous tissues (greater omentum as a source of peripheral nerves neovascularization shows promising re-sults. We proposed a surgical technique in which injured peripheral nerves anastomosis was wrapped in a pedicled muscular flap and performed morphological assessment of the efficacy of such technique with the aid of immunohistochemistry. 14 rats (which underwent sciatic nerve transection were operated according to proposed technique. Another 14 rats, in which only end-to-end nerve anastomosis (without muscular wrapping was performed served as controls. Morphological changes were evaluated at 3 weeks and 3 months periods. Higher blood vessel and axon counts were observed in experimental groups at both checkpoints. There was also an increase in Schwann cells and macrophages counts, and less collagen content in pe-ripheral nerves of experimental groups. Axons in neuromas of experimental groups showed a higher degree of arrangement. We conclude that proposed surgical technique provides better vascularisation of injured peripheral nerves, which is beneficial for nerve regeneration.

    This study assessed the efficacy and safety of guaifenesin 600 mg and pseudoephedrine hydrochloride 60 mg extended-release bilayer tablets in providing relief of acute respiratory symptoms when used as an adjunct to antibiotics in patients with an acute respiratory infection (ARI). Adult patients experiencing symptoms of ARI and meeting the physician's usual diagnostic criteria for oral antibiotic treatment were prescribed an antibiotic and randomized to adjunctive guaifenesin/pseudoephedrine hydrochloride or matching placebo twice daily for 7 days. Patients completed symptom diaries and treatment assessments twice daily and attended office visits on Days 4 and 8. The safety/intent-to-treat (ITT) population analysis included 601 patients (guaifenesin/pseudoephedrine, n = 303; placebo, n = 298). Mean symptom scores were lower with guaifenesin/pseudoephedrine from Day 3 for every symptom assessed, with statistically significant improvements in total symptom score from Day 3 (P = 0.026). The greatest effects of treatment with guaifenesin/pseudoephedrine were observed for nasal congestion and sinus headache. Time to overall relief was shorter with guaifenesin/pseudoephedrine (P = 0.038). Significantly more patients reported "the medication was helping during the day" on Day 2 with guaifenesin/pseudoephedrine (P = 0.002). Patient assessments of symptom relief showed a significant preference for guaifenesin/pseudoephedrine versus placebo (P = 0.021). Treatment with guaifenesin/pseudoephedrine was well tolerated. Insomnia (2.6%), nausea (2.3%), and headache (1.3%) were the most common treatment-related adverse effects. As adjunctive therapy for symptom relief for patients taking antibiotics for ARIs, guaifenesin/pseudoephedrine shortened time to relief and improved bothersome respiratory symptoms better than placebo, with greatest effects seen for nasal congestion and sinus headache.

    Full Text Available Carpal tunnel syndrome (CTS is the most common entrapment neuropathy and a frequent cause of sick leave because of work-related hand overload. The main treatment is operation. Aim: The aim of the study is to assess the usefulness of high frequency ultrasound in the postoperative evaluation of CTS treatment efficacy. Material and methods: Sixty-two patients (50 women and 12 men aged 28–70, mean age 55.2 underwent surgical treatment of CTS. Ultrasound examinations of the wrist in all carpal tunnel sufferers were performed 3 months after the procedure with the use of a high frequency broadband linear array transducer (6–18 MHz, using 18 MHz band of MyLab 70/Esaote. On the basis of the collected data, the author has performed multiple analyses to confirm the usefulness of ultrasound imaging for postoperative evaluation of CTS treatment efficacy. Results: Among all 62 patients, 3 months after surgical median nerve decompression: in 40 patients, CTS symptoms subsided completely, and sonographic evaluation did not show median nerve entrapment signs; in 9 patients, CTS symptoms persisted or exacerbated, and ultrasound proved nerve compression revealing preserved flexor retinaculum fibers; in 13 patients, scar tissue symptoms occurred, and in 5 of them CTS did not subside completely (although ultrasound showed no signs of compression. Conclusions: Ultrasound imaging with the use of a high frequency transducer is a valuable diagnostic tool for postoperative assessment of CTS treatment efficacy.

A total of 91 adult patients who were actively experiencing mandibular molar pain were involved in this study. The patients were randomly divided into three groups on the basis of the anesthetic solution used. The first group received IANB with 1.8 mL of 2% lidocaine with 1:200,000 epinephrine, the second group received IANB with 4% articaine with 1:100,000 epinephrine, and the third group received IANB with 0.5% bupivacaine with 1:200,000 epinephrine. After 15 minutes of IANB, conventional endodontic access preparation was started. The pain during the treatment was noted on a Heft-Parker visual analog scale (HP VAS). The primary outcome measure was anesthetic success, and anesthesia was considered successful if the patient reported no pain or weak/mild pain (HP VAS score 2% lidocaine, 4% articaine, and 0.5% bupivacaine were 23%, 33%, and 17%, respectively. The differences were statistically insignificant (P > .05). The 2% lidocaine solution used for IANB had similar success rates when compared with 4% articaine and 0.5% bupivacaine.

    Neuropathies of the shoulder are considered to be entrapment syndromes. They are relatively common, accounting for about 2% of cases of sport-related shoulder pain. Many instances involve suprascapular neuropathy, but the clinical diagnosis is often delayed because of nonspecific symptoms. Classically, EMG is the gold standard investigation but MRI currently reveals muscular abnormality in 50% of cases. Muscle edema, the most characteristic symptom, is nonspecific. In general, the topography of edema, the presence of a lesion compressing the nerve and clinical history contribute to the diagnosis. Although atrophy and fatty degeneration may persist after the disappearance of edema, they are rarely symptomatic. The main differential diagnosis is Parsonage–Turner syndrome. Evidence of a cyst pressing on a nerve may prompt puncture-infiltration guided by ultrasonography or CT-scan.

    The aim of this review of the literature is to summarize the state of the knowledge concerning the relationship between negative symptoms in schizophrenia, electrophysiology and electrotherapy. The scientific literature search of international articles was performed during August and September 2015 using the PubMed electronic database. We used the following MeSH terms: "Negative symptoms", "Schizophrenia", "Electrophysiology", "Neurophysiology", "EEG power", "Alpha rhythm", "Transcranial magnetic stimulation", "Transcranial direct current stimulation", "Electroconvulsive therapy", "Neurofeedback", "Vagus Nerve Stimulation", "Deep Brain Stimulation", and "State dependent". Negative symptoms in schizophrenia are associated with altered activity in prefrontal cortex in functional neuroimaging studies. This is in line with electrophysiological measurements that found a change in EEG spectral power in the alpha frequency band over prefrontal brain regions. The notion of functional hypofrontality has led to hypotheses that electrotherapy applied to the prefrontal cortex may be an effective treatment of negative symptoms in schizophrenia. Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) were used to increase cortical activity in schizophrenia and achieve a clinical effect on negative symptoms. Three meta-analyses confirmed, with a moderate effect size, that rTMS is an effective treatment option for negative symptoms in schizophrenia. The two subsequently published prospective multicenter studies, however, found opposite results from each other. Two randomized controlled studies suggested that tDCS is an effective treatment option for negative symptoms. There is no study on the efficacy of neurofeedback, vagal nerve stimulation or deep brain stimulation on negative symptoms in schizophrenia. Additional studies are needed to confirm the efficacy of rTMS and tDCS on negative symptoms in schizophrenia. Influencing factors

    Peripheral nerve injuries (PNIs) can be most disabling, resulting in the loss of sensitivity, motor function and autonomic control in the involved anatomical segment. Although injured peripheral nerves are capable of regeneration, sub-optimal recovery of function is seen even with the best reconstruction. Distal axonal degeneration is an unavoidable consequence of PNI. There are currently few strategies aimed to maintain the distal pathway and/or target fidelity during regeneration across the zone of injury. The current state of the art approaches have been focussed on the site of nerve injury and not on their distal muscular targets or representative proximal cell bodies or central cortical regions. This is a comprehensive literature review of the neurochemistry of peripheral nerve regeneration and a state of the art analysis of experimental compounds (inorganic and organic agents) with demonstrated neurotherapeutic efficacy in improving cell body and neuron survival, reducing scar formation and maximising overall nerve regeneration.

Methods: The study included 176 patients from a private clinic undergoing transforaminal injection performed by a single spinal surgeon. The patients were assessed after two weeks, three months and six months regarding to the improvement of the pain radiating to the lower limbs. In case of persistent symptoms, patients could choose to perform a new nerve root block and maintenance of physical therapy or be submitted to conventional microdiscectomy. Results: By the end of six-month follow-up of the 176 patients, 116 had a favorable outcome (95 after one block and 21 after two blocks, and only 43 required surgery. Conclusion: The results of our study suggest a positive effect of transforaminal block for the treatment of sciatica in patients with lumbar disc herniation.

  1. Optical Biopsy of Peripheral Nerve Using Confocal Laser Endomicroscopy: A New Tool for Nerve Surgeons?

    Full Text Available Peripheral nerve injuries remain a challenge for reconstructive surgeons with many patients obtaining suboptimal results. Understanding the level of injury is imperative for successful repair. Current methods for distinguishing healthy from damaged nerve are time consuming and possess limited efficacy. Confocal laser endomicroscopy (CLE is an emerging optical biopsy technology that enables dynamic, high resolution, sub-surface imaging of live tissue. Porcine sciatic nerve was either left undamaged or briefly clamped to simulate injury. Diluted fluorescein was applied topically to the nerve. CLE imaging was performed by direct contact of the probe with nerve tissue. Images representative of both damaged and undamaged nerve fibers were collected and compared to routine H&E histology. Optical biopsy of undamaged nerve revealed bands of longitudinal nerve fibers, distinct from surrounding adipose and connective tissue. When damaged, these bands appear truncated and terminate in blebs of opacity. H&E staining revealed similar features in damaged nerve fibers. These results prompt development of a protocol for imaging peripheral nerves intraoperatively. To this end, improving surgeons' ability to understand the level of injury through real-time imaging will allow for faster and more informed operative decisions than the current standard permits.

    Cervical traction is a frequently used treatment in rehabilitation clinics for cervical spine problems. This modality works, in principle, by decompressing the spinal cord or its nerve roots by applying traction on the cervical spine through a harness placed over the mandible (Olivero et al., Neurosurg Focus 2002;12:ECP1). Previous reports on treatment complications include lumbar radicular discomfort, muscle injury, neck soreness, and posttraction pain (LaBan et al., Arch Phys Med Rehabil 1992;73:295-6; Lee et al., J Biomech Eng 1996;118:597-600). Here, we report the first case of unilateral facial nerve paralysis developed after 4 wks of intermittent cervical traction therapy. Nerve conduction velocity examination revealed a peripheral-type facial nerve paralysis. Symptoms of facial nerve paralysis subsided after prednisolone treatment and suspension of traction therapy. It is suspected that a misplaced or an overstrained harness may have been the cause of facial nerve paralysis in this patient. Possible causes were (1) direct compression by the harness on the right facial nerve near its exit through the stylomastoid foramen; (2) compression of the right external carotid artery by the harness, causing transient ischemic injury at the geniculate ganglion; or (3) coincidental herpes zoster virus infection or idiopathic Bell's palsy involving the facial nerve.

    Full Text Available Introduction: The inferior alveolar nerve block (IAN is the most frequently used mandibular injection technique for achieving local anesthesia in endodontics. Supplemental injections are essential to overcome failure of IAN block in patients with irreversible pulpitis. Aim: To evaluate the anesthetic efficacy of X-tip intraosseous injection (2% lidocaine with 1:80,000 epinephrine in patients with irreversible pulpitis in mandibular posterior teeth when conventional IAN block failed. Materials and Methods: Thirty emergency patients diagnosed with irreversible pulpitis in a mandibular posterior tooth received an IAN block and experienced moderate to severe pain on endodontic access or initial instrumentation. The X-tip system was used to administer 1.8 ml of 2% lidocaine with 1:80,000 epinephrine. The success of X-tip intraosseous injection was defined as none or mild pain (Heft-Parker visual analogue scale ratings < 54 mm on endodontic access or initial instrumentation. Results: Ninety-three percent of X-tip injections were successful and 7% were unsuccessful. Discomfort rating for X-tip perforation: 96.66% patients reported none or mild pain, whereas 3.34% reported moderate to severe pain. For discomfort rating during solution deposition, 74.99% patients reported none or mild pain and 24.92% reported moderate to severe pain. Ninety-six percent of the patients had subjective/objective increase in heart rate. Conclusions: Supplemental X-tip intraosseous injection using 2% lignocaine with 1:80,000 epinephrine has a statistically significant influence in achieving pulpal anesthesia in patients with irreversible pulpitis.

  10. Enabling symptom self-management via use of an electronic patient-reported outcomes (ePRO system to increase self-efficacy of patients with cancer receiving active chemotherapy treatment

    Full Text Available Background: In recent years, the shift in cancer services from traditional tertiary care to care delivered within communities has increased the need for patients to engage in self-care activities in order to prevent or reduce the severity of numerous and complex-side effects (McCorkle et al., 2011 and make important health decisions when at home in the absence of clinicians (Butow et al., 2012. The actual degree of engagement in self-management may be dependent on patients’ perceived competence or self-efficacy to perform such activities (Fenlon et al., 2015. Self-efficacy has been defined as “a person’s belief to execute courses of action required to deal with a prospective situation” (Bandura, 1977, 2001. One’s beliefs in their capability to successfully manage tasks and consequently influence situations that impact their lives constitutes a central part of human agency, and can be influenced by performance accomplishments (Bandura, 1989, 2001. Whilst self-efficacy can enable engagement in self-management, actual participation in self-management activities can further increase one’s perceived ability to undertake such activities; it is thus obvious that a bi-directional association between self-management and self-efficacy exists. Supporting a shift in clinical practice with innovative technological systems affords a solution to the increasing demands placed on acute care by enabling the delivery of care in the home and community setting (Basch et al., 2011; Carpenter et al., 2008. Such remote monitoring systems facilitate the provision of clear lines of real-time communication between patients and their health care providers (Basch et al., 2011, and can deliver organised self-management advice tailored to the individual’s clinical characteristics and severity/distress of symptoms of anti-cancer treatment.

    A preliminary study by our research group showed that 6-mm-long regeneration chamber bridging is equivalent to autologous nerve transplantation for the repair of 12-mm nerve defects.In this study,we compared the efficacy of different lengths (6,8,10 mm) of nerve fragments bridging 6-mm regeneration chambers for the repair of 12-mm-long nerve defects.At 16 weeks after the regeneration chamber was implanted,the number,diameter and myelin sheath thickness of the regenerated nerve fibers,as well as the conduction velocity of the sciatic nerve and gastrocnemius muscle wet weight ratio,were similar to that observed with autologous nerve transplantation.Our results demonstrate that 6-,8-and 10-mm-long nerve fragments bridging 6-mm regeneration chambers effectively repair 12-mm-long nerve defects.Because the chemoattractive capacity is not affected by the length of the nerve fragment,we suggest adopting 6-mm-long nerve fragments for the repair of peripheral nerve defects.

    To compare the extent of sensory and motor block with two different nerve stimulation techniques in axillary blocks. Prospective, randomized, investigator-blinded study. Ambulatory surgery unit of a university hospital. 60 ASA physical status I, II, and III patients undergoing surgery at or below the elbow. Patients receiving axillary block were randomized into two nerve stimulation groups with either radial plus musculocutaneous or triple nerve stimulation (radial, median, and musculocutaneous nerves). Thirty milliliters of plain 2% mepivacaine was given to all patients either in a single or fractionated dosing for radial or for radial and median nerves, according to group assignment. Five milliliters of plain 1% mepivacaine for the musculocutaneous nerve was given to all patients. Blocks were assessed at 10, 20, and 30 minutes. Rates of supplementation given as a result of insufficient surgical anesthesia were also noted. Statistically significantly higher rates of anesthesia at the cutaneous distributions of median and medial cutaneous of the arm nerves with multiple nerve stimulation at 30 minutes were found as compared with radial plus musculocutaneous nerve stimulation. The rate of supplementation was lower with multiple nerve stimulation. Radial plus musculocutaneous nerve stimulation showed lower efficacy of axillary block than did triple nerve stimulation when using 2% mepivacaine.

    Nerve growth factor over expression in the bladder has a role in overactive bladder symptoms via the mediation of functional changes in bladder afferent pathways. We studied whether blocking nerve growth factor over expression in bladder urothelium by a sequence specific gene silencing mechanism would suppress bladder overactivity and chemokine expression induced by acetic acid. Female Sprague-Dawley® rats anesthetized with isoflurane were instilled with 0.5 ml saline, scrambled or TYE™ 563 labeled antisense oligonucleotide targeting nerve growth factor (12 μM) alone or complexed with cationic liposomes for 30 minutes. The efficacy of nerve growth factor antisense treatments for acetic acid induced bladder overactivity was assessed by cystometry. Bladder nerve growth factor expression levels and cellular distribution were quantified by immunofluorescence staining and enzyme-linked immunosorbent assay. Effects on bladder chemokine expression were measured by Luminex® xMAP® analysis. Liposomes were needed for bladder uptake of oligonucleotide, as seen by the absence of bright red TYE 563 fluorescence in rats instilled with oligonucleotide alone. At 24 hours after liposome-oligonucleotide treatment baseline bladder activity during saline infusion was indistinct in the sham and antisense treated groups with a mean ± SEM intercontraction interval of 348 ± 55 and 390 ± 120 seconds, respectively. Acetic acid induced bladder overactivity was shown by a decrease in the intercontraction interval to a mean of 33.2% ± 4.0% of baseline in sham treated rats. However, the reduction was blunted to a mean of 75.8% ± 3.4% of baseline in rats treated with liposomal antisense oligonucleotide (p antisense treatment, as shown by enzyme-linked immunosorbent assay and reduced nerve growth factor immunoreactivity in the urothelium. Increased nerve growth factor in bladder tissue was associated with sICAM-1, sE-selectin, CXCL-10 and 1, leptin, MCP-1 and vascular endothelial

    The neural regeneration and functional recovery after nerve injuries has long been an important field in neuroscience. Low intensity laser (LIL) irradiation is a novel and useful tool for the treatment of many injuries and disorders. The aim of this study was to assess the role of LIL irradiation in the treatment of peripheral and central nerve injuries. Some animal experiments and clinical investigations have shown beneficial effects of LIL irradiation on neural tissues, but its therapeutic value and efficacy are controversial. Reviewing the data of experimental and clinical studies by using the biological information model of photobiomodulation, we conclude that LIL irradiation in specific parameters can promote the regeneration of injured peripheral and central nerves and LIL therapy is a safe and valuable treatment for superficial peripheral nerve injuries and spinal cord injury. The biological effects of LIL treatment depend largely on laser wavelength, power and dose per site and effective irradiation doses are location-specific.

    To evaluate whether the daily intake of synbiotics interferes in radiation-induced acute proctitis symptoms and in quality of life in patients with prostate cancer. Twenty patients who underwent 3-dimensional conformal radiation therapy for prostate cancer were randomized to intake either a synbiotic powder containing Lactobacillus reuteri 10(8) colony-forming units and 4.3 g of soluble fiber (Nestlé) or placebo. The questionnaire EORTC QLQ-PRT23 was applied before the beginning of radiation therapy and in every week for the first 4 weeks of treatment. The sum of both the complete (proctitis symptoms plus quality of life) and partial (proctitis symptoms) scores of the EORTC QLQ-PRT23 (European Organization for Research and Treatment of Cancer Quality of Life Module for Proctitis-23 items) questionnaire were the main endpoints. This pilot study showed that the complete questionnaire score (median [range]) was higher in the second (23 [21-30] vs 26.5 [22-34], P<.05) and third (23 [21-32] vs 27.5 [24-33], P<.01) weeks in the placebo group. Proctitis symptoms were highest scored in the placebo group in both the second (19.5 [16-25]) and third (19 [17-24]) weeks than in the synbiotic group (week 2: 16.5 [15-20], P<.05; week 3: 17 [15-23], P<.01). In both scores the placebo group had a significantly higher result (P<.01) than the synbiotic group (repeated-measures analysis of variance).

    Self-guided internet-based cognitive behavioral therapy (iCBT) has the potential to increase access and availability of evidence-based therapy and reduce the cost of depression treatment. To estimate the effect of self-guided iCBT in treating adults with depressive symptoms compared with controls and evaluate the moderating effects of treatment outcome and response. A total of 13 384 abstracts were retrieved through a systematic literature search in PubMed, Embase, PsycINFO, and Cochrane Library from database inception to January 1, 2016. Randomized clinical trials in which self-guided iCBT was compared with a control (usual care, waiting list, or attention control) in individuals with symptoms of depression. Primary authors provided individual participant data from 3876 participants from 13 of 16 eligible studies. Missing data were handled using multiple imputations. Mixed-effects models with participants nested within studies were used to examine treatment outcomes and moderators. Outcomes included the Beck Depression Inventory, Center for Epidemiological Studies-Depression Scale, and 9-item Patient Health Questionnaire scores. Scales were standardized across the pool of the included studies. Of the 3876 study participants, the mean (SD) age was 42.0 (11.7) years, 2531 (66.0%) of 3832 were female, 1368 (53.1%) of 2574 completed secondary education, and 2262 (71.9%) of 3146 were employed. Self-guided iCBT was significantly more effective than controls on depressive symptoms severity (β = -0.21; Hedges g  = 0.27) and treatment response (β = 0.53; odds ratio, 1.95; 95% CI, 1.52-2.50; number needed to treat, 8). Adherence to treatment was associated with lower depressive symptoms (β = -0.19; P = .001) and greater response to treatment (β = 0.90; P depressive symptoms. The use of meta-analyses of individual participant data provides substantial evidence for clinical and policy decision making because self-guided iCBT can be considered

    Patients with cardiovascular diseases managed by a person-centered care (PCC) approach have been observed to have better treatment outcomes and satisfaction than with traditional care. eHealth may facilitate the often slow transition to more person-centered health care by increasing patients' beliefs in their own capacities (self-efficacy) to manage their care trajectory. eHealth is being increasingly used, but most studies continue to focus on health care professionals' logic of care. Knowledge is lacking regarding the effects of an eHealth tool on self-efficacy when combined with PCC for patients with chronic heart diseases. The objective of our study was to investigate the effect of an eHealth diary and symptom-tracking tool in combination with PCC for patients with acute coronary syndrome (ACS). This was a substudy of a randomized controlled trial investigating the effects of PCC in patients hospitalized with ACS. In total, 199 patients with ACS aged eHealth tool, or both, for at least 2 months after hospital discharge. The primary end point was a composite score of changes in general self-efficacy, return to work or prior activity level, and rehospitalization or death 6 months after discharge. Of the 94 patients in the intervention arm, 37 (39%) used the eHealth tool at least once after the index hospitalization. Most of these (24/37, 65%) used the mobile app and not the Web-based app as the primary source of daily self-rating input. Patients used the eHealth tool a mean of 38 times during the first 8 weeks (range 1-118, SD 33) and 64 times over a 6-month period (range 1-597, SD 104). Patients who used the eHealth tool in combination with the PCC intervention had a 4-fold improvement in the primary end point compared with the control group (odds ratio 4.0, 95% CI 1.5-10.5; P=.005). This improvement was driven by a significant increase in general self-efficacy compared with the control group (P=.011). Patients in the PCC group who did not use the eHealth tool

    Full Text Available Introduction. Neurofeedback (NF is an adjuvant or alternative therapy for children with Attention Deficit Hyperactivity Disorder (ADHD. This study intended to compare the efficacy of two different NF protocols on clinical and cognitive symptoms of ADHD. Materials and Methods. In this clinical trial, sixty children with ADHD aged 7 to 10 years old were randomly grouped to receive two different NF treatments (theta suppression/beta enhancement protocol and theta suppression/alpha enhancement protocol. Clinical and cognitive assessments were conducted prior to and following the treatment and also after an eight-week follow-up. Results. Both protocols alleviated the symptoms of ADHD in general (p<0.001, hyperactivity (p<0.001, inattention (p<0.001, and omission errors (p<0.001; however, they did not affect the oppositional and impulsive scales nor commission errors. These effects were maintained after an eight-week intervention-free period. The only significant difference between the two NF protocols was that high-frequency alpha enhancement protocol performed better in suppressing omission errors (p<0.001. Conclusion. The two NF protocols with theta suppression/beta enhancement and theta suppression/alpha enhancement have considerable and comparable effect on clinical symptoms of ADHD. Alpha enhancement protocol was more effective in suppressing omission errors.

    Nasal spray from lemon and quince (LQNS) is used to treat hay fever symptoms and has been shown to inhibit histamine release from mast cells in vitro. Forty-three patients with grass pollen allergy (GPA) were randomized to be treated either with placebo or LQNS for one week, respectively, in a cross-over study. At baseline and after the respective treatments patients were provoked with grass pollen allergen. Outcome parameters were nasal flow measured with rhinomanometry (primary), a nasal symptom score, histamine in the nasal mucus and tolerability. In the per protocol population absolute inspiratory nasal flow 10 and 20 min after provocation was higher with LQNS compared to placebo (-37 ± 87 mL/s; p = 0.027 and -44 ± 85 mL/s; p = 0.022). The nasal symptom score showed a trend (3.3 ± 1.8 in the placebo and 2.8 ± 1.5 in the LQNS group; p = 0.070) in favor of LQNS; the histamine concentration was not significantly different between the groups. Tolerability of both, LQNS and placebo, was rated as very good. LQNS seems to have an anti-allergic effect in patients with GPA. Copyright © 2016 John Wiley & Sons, Ltd.

    Inflammatory processes as well as primary and secondary tumorous changes may involve cranial nerves causing neurological deficits. In addition to neurologists, ENT physicians, ophthalmologists and maxillofacial surgeons, radiologists play an important role in the investigation of patients with cranial nerve symptoms. Multidetector computed tomography (MDCT) and particularly magnetic resonance imaging (MRI) allow the depiction of the cranial nerve anatomy and pathological neural changes. This article briefly describes the imaging techniques in MDCT and MRI and is dedicated to the radiological presentation of inflammatory and tumorous cranial nerve pathologies.

    The accepted model for nerve pulse propagation in biological membranes seems insufficient. It is restricted to dissipative electrical phenomena and considers nerve pulses exclusively as a microscopic phenomenon. A simple thermodynamic model that is based on the macroscopic properties of membranes allows explaining more features of nerve pulse propagation including the phenomenon of anesthesia that has so far remained unexplained.

  12. Impaired Prosaposin Secretion During Nerve Regeneration in Diabetic Rats and Protection of Nerve Regeneration by a Prosaposin-Derived Peptide

    Prosaposin is both a precursor of sphingolipid activator proteins and a secreted neurotrophic and myelinotrophic factor. Because peripheral nerve regeneration is impaired in diabetes mellitus, we measured prosaposin protein levels from control and streptozotocin-diabetic rats by collecting endoneurial fluid secreted into a bridging tube connecting the ends of transected sciatic nerve. Prosaposin protein levels were significantly reduced in endoneurial fluid from diabetic rats and increased in the proximal nerve stump compared to controls. To investigate whether a prosaposin-derived peptide could improve nerve regeneration, rats were treated with prosaptide TX14(A) following sciatic nerve crush. In control rats, TX14(A) was without effect in the uninjured nerve but shortened toe spread recovery time after nerve crush. In diabetic rats, efficacy of prosaptide TX14(A) was confirmed by correction of thermal hypoalgesia, formalin-evoked hyperalgesia and conduction slowing in the uninjured nerve. The peptide also prevented diabetes-induced abnormalities in nerve regeneration distance and mean axonal diameter of regenerated axons, whereas delayed recovery of toe spread was not improved. Muscle denervation atrophy was attenuated by TX14(A) in both control and diabetic rats. These results suggest that reduced prosaposin secretion after nerve injury may contribute to impaired regeneration rates in diabetic rats and that prosaptide TX14(A) can improve aspects of nerve regeneration.

  14. Sensory symptom profiles and co-morbidities in painful radiculopathy.

    Friederike Mahn

    Full Text Available Painful radiculopathies (RAD and classical neuropathic pain syndromes (painful diabetic polyneuropathy, postherpetic neuralgia show differences how the patients express their sensory perceptions. Furthermore, several clinical trials with neuropathic pain medications failed in painful radiculopathy. Epidemiological and clinical data of 2094 patients with painful radiculopathy were collected within a cross sectional survey (painDETECT to describe demographic data and co-morbidities and to detect characteristic sensory abnormalities in patients with RAD and compare them with other neuropathic pain syndromes. Common co-morbidities in neuropathic pain (depression, sleep disturbance, anxiety do not differ considerably between the three conditions. Compared to other neuropathic pain syndromes touch-evoked allodynia and thermal hyperalgesia are relatively uncommon in RAD. One distinct sensory symptom pattern (sensory profile, i.e., severe painful attacks and pressure induced pain in combination with mild spontaneous pain, mild mechanical allodynia and thermal hyperalgesia, was found to be characteristic for RAD. Despite similarities in sensory symptoms there are two important differences between RAD and other neuropathic pain disorders: (1 The paucity of mechanical allodynia and thermal hyperalgesia might be explained by the fact that the site of the nerve lesion in RAD is often located proximal to the dorsal root ganglion. (2 The distinct sensory profile found in RAD might be explained by compression-induced ectopic discharges from a dorsal root and not necessarily by nerve damage. These differences in pathogenesis might explain why medications effective in DPN and PHN failed to demonstrate efficacy in RAD.

    After reading this article, the participant should be able to: 1. Identify the prerequisite conditions to perform a tendon or a nerve transfer. 2. Detail some of the current nerve and tendon transfer options in upper extremity peripheral nerve injuries. 3. Understand the advantages and disadvantages of tendon and nerve transfers used in isolation and in combination. 4. Appreciate the controversies that surround the nerve/tendon transfers. 5. Realize the treatment outcomes of peripheral nerve injuries. Traditional treatment of a Sunderland fourth- or fifth-degree peripheral nerve injury has been direct neurorrhaphy, nerve grafting, or tendon transfers. With increasing knowledge of nerve pathophysiology, additional treatment options such as nerve transfers have become increasingly popular. With an array of choices for treating peripheral nerve injuries, there is debate as to whether tendon transfers and/or nerve transfers should be performed to restore upper extremity function. Often, tendon and nerve transfers are used in combination as opposed to one in isolation to obtain the most normal functioning extremity without unacceptable donor deficits. The authors tend to prefer reconstructive techniques that have proven long-term efficacy to restore function. Nerve transfers are becoming more common practice, with excellent results; however, the authors are wary of using nerve transfers that sacrifice possible secondary tendon reconstruction should the nerve transfer fail.

In a prospective, randomized, double-blind, and placebo-controlled phase III clinical trial, the effect of daily intravaginal 0.50% DHEA (6.5 mg) (Prasterone, EndoCeutics) was examined on four coprimary objectives, namely percentage of parabasal cells, percentage or superficial cells, vaginal pH, and moderate to severe pain at sexual activity (dyspareunia) identified by the women as their most bothersome vulvovaginal atrophy symptom. The intent-to-treat population included 157 and 325 women in the placebo and DHEA-treated groups, respectively. After daily intravaginal administration of 0.50% DHEA for 12 weeks, when compared to baseline by the analysis of covariance test, the percentage of parabasal cells decreased by 27.7% over placebo (P DHEA (Prasterone) has shown clinically and highly statistically significant effects on the four coprimary parameters suggested by the US Food and Drug Administration.

    Peripheral neuropathies are a frequent, but often underdiagnosed, cause of pain and functional impairment. The clinical symptoms can be subtle, and other neurologic or non neurologic clinical entities are often evoked. MRI and ultrasonography are the imaging modalities of choice for depicting nerves and assessing neuropathies. Common neuropathies in the knee area involve the saphenous, the tibial, the common peroneal and the sural nerves. The most frequent mechanisms of nerve injury in this area are nerve entrapment and nerve stretching. A perfect knowledge of the normal imaging anatomy is essential for accurate assessment of neuropathies. In this article, we will review the anatomy of the nerves around the knee, and their normal and pathological appearance.

    Pudendal nerve block is a safe and effective pain relief method for vaginal birth. Providing analgesia to the vulva and anus, it is used for operative vaginal birth and subsequent repair, late second stage pain relief with spontaneous vaginal birth, repair of complex lacerations, or repair of lacerations in women who are unable to achieve adequate or satisfactory pain relief during perineal repair with local anesthesia. Key to its efficacy is the knowledge of pudendal nerve anatomy, the optimal point of infiltration of local anesthetic, and an understanding of the amount of time necessary to effect adequate analgesia.

    Radical neck dissection was the golden standard of treatment for cervical nodes in head and neck tumors. From the seventies, the preservation of the spinal accessory nerve has become increasingly popular in order to improve the functional result of the neck dissections. The aim of this study was to assess the degree of functional disability associated with each type of neck dissection and the value of anatomical references for dissection of the spinal accessory nerve. One hundred twenty seven patients were evaluated 1 month and 1 year after radical, functional or supraomohyoid neck dissection with a questionnaire and a physical examination. Anatomical measurements of the spinal accessory nerve were performed in 20 patients. We found considerable or severe shoulder dysfunction in 7%, 34% and 51% respectively of patients in whom supraomohyoid, functional and radical neck dissections were performed. Furthermore 49% of patients having undergone a radical neck dissection had little or no symptoms. Sacrifice of the spinal accessory nerve in radical neck dissection may lead to shoulder dysfunction. A functional disability may also be associated, although in a less extent, with any neck dissection in which the spinal accessory nerve is dissected and placed in traction. There is a large variation in the degree of functional disability and pain in patients with similar neck dissections. The course of the spinal accessory nerve in the neck makes it particularly vulnerable to injury during the dissection near the sternocleidomastoid muscle and in the posterior cervical triangle.

    Trauma injuries often cause peripheral nerve damage and disability. A goal in neural tissue engineering is to develop synthetic nerve conduits for peripheral nerve regeneration having therapeutic efficacy comparable to that of autografts. Nanofibrous conduits with aligned nanofibers have been shown to promote nerve regeneration, but current fabrication methods rely on rolling a fibrous sheet into the shape of a conduit, which results in a graft with inconsistent size and a discontinuous joint or seam. In addition, the long-term effects of nanofibrous nerve conduits, in comparison with autografts, are still unknown. Here we developed a novel one-step electrospinning process and, for the first time, fabricated a seamless bi-layer nanofibrous nerve conduit: the luminal layer having longitudinally aligned nanofibers to promote nerve regeneration, and the outer layer having randomly organized nanofibers for mechanical support. Long-term in vivo studies demonstrated that bi-layer aligned nanofibrous nerve conduits were superior to random nanofibrous conduits and had comparable therapeutic effects to autografts for nerve regeneration. In summary, we showed that the engineered nanostructure had a significant impact on neural tissue regeneration in situ. The results from this study will also lead to the scalable fabrication of engineered nanofibrous nerve conduits with designed nanostructure. This technology platform can be combined with drug delivery and cell therapies for tissue engineering. PMID:21501089

    2016-01-01

    Sciatica may result from pathologies affecting the nerve both in its intraspinal and extraspinal course. In daily routine, the vast majority of cases are caused by herniation of the lumbar discs compressing the neural roots. Extraspinal causes of sciatic pain are usually underestimated and the imaging study may be completed after reporting the lumbar MRIs. However, early diagnosis of the exact etiology of sciatica is paramount for both relieving the symptoms and preventing any additional neurologic injury. In this pictorial assay, some relatively rare causes of sciatic neuralgia along the route of the sciatic nerve after leaving the sacral foramen will be displayed. PMID:27670092

Further, the functionality of sciatic nerve was assessed using the histopathological study of myelinated and unmyelinated fibers in sciatic nerve. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances (TBARS, catalase, glutathione and tissue TBARS and Superoxide dismutase (SOD. Rats exposed to sciatic nerve ligation produced marked increase in oxidative stress, which was assessed in terms of TBARS and SOD along with decrease in the level of catalase and glutathione. Moreover, it develops neuropathic pain by impairing the normal functions of myelinated and unmyelinated fibers in sciatic nerve. Treatment with aqueous extract of Punica granatum extract (100mg/kg, p.o markedly prevented sciatic nerve ligation-induced neuropathy and oxidative stress by increasing the pain threshold, by improving the functionality of sciatic nerve, by decreasing serum and tissue TBARS and tissue SOD, by increasing levels of serum glutathione and catalase. It may be concluded that Punica granatum extract reduced the oxidative stress via inhibiting p38MAPK and alleviates neuropathic symptoms and consequently improved the functionality of sciatic nerve and prevents sciatic nerve ligation–induced neuropathic pain.

    Full Text Available Objective. Guiding Regeneration Gel (GRG was developed in response to the clinical need of improving treatment for peripheral nerve injuries and helping patients regenerate massive regional losses in peripheral nerves. The efficacy of GRG based on tissue engineering technology for the treatment of complete peripheral nerve injury with significant loss defect was investigated. Background. Many severe peripheral nerve injuries can only be treated through surgical reconstructive procedures. Such procedures are challenging, since functional recovery is slow and can be unsatisfactory. One of the most promising solutions already in clinical practice is synthetic nerve conduits connecting the ends of damaged nerve supporting nerve regeneration. However, this solution still does not enable recovery of massive nerve loss defect. The proposed technology is a biocompatible and biodegradable gel enhancing axonal growth and nerve regeneration. It is composed of a complex of substances comprising transparent, highly viscous gel resembling the extracellular matrix that is almost impermeable to liquids and gasses, flexible, elastic, malleable, and adaptable to various shapes and formats. Preclinical study on rat model of peripheral nerve injury showed that GRG enhanced nerve regeneration when placed in nerve conduits, enabling recovery of massive nerve loss, previously unbridgeable, and enabled nerve regeneration at least as good as with autologous nerve graft “gold standard” treatment.

    Of all cranial nerves, the trigeminal nerve is the largest and the most widely distributed in the supra-hyoid neck. It provides sensory input from the face and motor innervation to the muscles of mastication. In order to adequately image the full course of the trigeminal nerve and its main branches a detailed knowledge of neuroanatomy and imaging technique is required. Although the main trunk of the trigeminal nerve is consistently seen on conventional brain studies, high-resolution tailored imaging is mandatory to depict smaller nerve branches and subtle pathologic processes. Increasing developments in imaging technique made possible isotropic sub-milimetric images and curved reconstructions of cranial nerves and their branches and led to an increasing recognition of symptomatic trigeminal neuropathies. Whereas MRI has a higher diagnostic yield in patients with trigeminal neuropathy, CT is still required to demonstrate the bony anatomy of the skull base and is the modality of choice in the context of traumatic injury to the nerve. Imaging of the trigeminal nerve is particularly cumbersome as its long course from the brainstem nuclei to the peripheral branches and its rich anastomotic network impede, in most cases, a topographic approach. Therefore, except in cases of classic trigeminal neuralgia, in which imaging studies can be tailored to the root entry zone, the full course of the trigeminal nerve has to be imaged. This article provides an update in the most recent advances on MR imaging technique and a segmental imaging approach to the most common pathologic processes affecting the trigeminal nerve.

    Full Text Available Objectives: The purpose of present article was to review aetiological factors, mechanism, clinical symptoms, and diagnostic methods as well as to create treatment guidelines for the management of inferior alveolar nerve injury during dental implant placement.Material and Methods: Literature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were inferior alveolar nerve injury, inferior alveolar nerve injuries, inferior alveolar nerve injury implant, inferior alveolar nerve damage, inferior alveolar nerve paresthesia and inferior alveolar nerve repair. The search was restricted to English language articles, published from 1972 to November 2010. Additionally, a manual search in the major anatomy, dental implant, periodontal and oral surgery journals and books were performed. The publications there selected by including clinical, human anatomy and physiology studies.Results: In total 136 literature sources were obtained and reviewed. Aetiological factors of inferior alveolar nerve injury, risk factors, mechanism, clinical sensory nerve examination methods, clinical symptoms and treatment were discussed. Guidelines were created to illustrate the methods used to prevent and manage inferior alveolar nerve injury before or after dental implant placement.Conclusions: The damage of inferior alveolar nerve during the dental implant placement can be a serious complication. Clinician should recognise and exclude aetiological factors leading to nerve injury. Proper presurgery planning, timely diagnosis and treatment are the key to avoid nerve sensory disturbances management.

    BACKGROUND: Schwann cells are the most commonly used cells for tissue-engineered nerves. However, autologous Schwann cells are of limited use in a clinical context, and allogeneic Schwann cells induce immunological rejections. Cells that do not induce immunological rejections and that are relatively easy to acquire are urgently needed for transplantation.OBJECTIVE: To bridge sciatic nerve defects using tissue engineered nerves constructed with neural tissue-committed stem cells (NTCSCs) derived from bone marrow; to observe morphology and function of rat nerves following bridging; to determine the effect of autologous nerve transplantation, which serves as the gold standard for evaluating efficacy of tissue-engineered nerves.DESIGN, TIME AND SETTING: This randomized, controlled, animal experiment was performed in the Anatomical laboratory and Biomedical Institute of the Second Military Medical University of Chinese PLA between September 2004 and April 2006.MATERIALS: Five Sprague Dawley rats, aged 1 month and weighing 100-150 g, were used for cell culture. Sixty Sprague Dawiey rats aged 3 months and weighing 220-250 g, were used to establish neurological defect models. Nestin, neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP), and S-100 antibodies were provided by Santa Cruz Biotechnology, Inc., USA. Acellular nerve grafts were derived from dogs.METHODS: All rats, each with 1-cm gap created in the right sciatic nerve, were randomly assigned to three groups. Each group comprised 20 rats. Autograft nerve transplantation group: the severed 1-cm length nerve segment was reverted, but with the two ends exchanged; the proximal segment was sutured to the distal sciatic nerve stump and the distal segment to the proximal stump. Blank nerve scaffold transplantation group: a 1-cm length acellular nerve graft was used to bridge the sciatic nerve gap. NTCSC engineered nerve transplantation group: a 1-cm length acellular nerve graft, in which NTCSCs were

    Background There is still controversy as to whether initial combination treatment is superior to serial addition of anticholinergics after maintenance or induction of alpha blockers in benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) Objective The objective of this study was to determine the benefits and safety of initial combination treatment of an alpha blocker with anticholinergic medication in BPH/LUTS through a systematic review and meta-analysis. Methods We conducted a meta-analysis of improvement in LUTS using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QoL). Results In total, 16 studies were included in our analysis, with a total sample size of 3,548 subjects (2,195 experimental subjects and 1,353 controls). The mean change in total IPSS improvement from baseline in the combination group versus the alpha blocker monotherapy group was -0.03 (95% CI: -0.14–0.08). The pooled overall SMD change of storage IPSS improvement from baseline was -0.28 (95% CI: -0.40 - -0.17). The pooled overall SMD changes of QoL, Qmax, and PVR were -0.29 (95% CI: -0.50 - -0.07), 0.00 (95% CI: -0.08–0.08), and 0.56 (95% CI: 0.23–0.89), respectively. There was no significant difference in the number of acute urinary retention (AUR) events or PVR. Conclusions Initial combination treatment of an alpha blocker with anticholinergic medication is efficacious for in BPH/ LUTS with improved measures such as storage symptoms and QoL without causing significant deterioration of voiding function.

    To determine the significance of nerve root contrast enhancement in patients with residual or recurrent symptomatic postoperative lumbar spine. Eighty-eight patients with 116 postoperative lumbar disc lesions causing radiating back pain underwent enhanced MR imaging. Intradural nerve root enhancement was quantified by pixel measurement, and affected nerve roots were compared before and after contrast administration. Extradural nerve root enhancement was assessed visually, and nerve root enhancement and clinical symptoms were correlated. Associated lesions such as recurrent disc herniation, scar tissue, nerve root thickening and nerve root displacement were also evaluated. Of 26 cases (22.4%) involving intradural nerve root enhancement, 22 (84.6%) showed significant clinical symptoms (p=0.002). and of 59 (50.9%) demonstrating extradural enhancement, clinical symptoms showed significant correlation in 47 (79.7%) (p=0.001). Nerve root enhancement, including eleven cases where this was both intra-and extradural, showed highly significant association with clinical symptoms in 74 of the 116 cases (63.8%) (p=0.000). Among 33 cases (28.4%) of recurrent disc herniation, nerve root enhancement was observed in 28 (84.8%) and in 24 of these 28 (85.7%), significant correlation with clinical symptoms was observed (p=0.000). Where epidural fibrosis was present, correlation between nerve root enhancement and clinical symptoms was not significant (p>0.05). Nerve root thickening and displaced nerve root were, however, significantly associated with symptoms (87.2% and 88.6%, respectively). In patients with postoperative lumbar spine, the association between nerve root enhancement revealed by MRI and clinical symptoms was highly significant.

    Full Text Available Psychiatry in Ayurveda is called Bhootavidya. All mental disorders come under bhootavidya. Various types of treatment modalities are described in Ayurvedic classics for mental disorders. They include spiritual healing, psychotherapy and pharmacotherapy. Ayurvedic treatment is based on balancing of humors of body and mind. So, adverse effects are comparatively less.But, only a few of the formulations and treatment modalities are in practice today. There is much to be studied on. One among them is Sidharthakadi Yoga. The indication is in graha especially Asuragraha. Asuragraha has features like anger, hyperactivity, grandiosity and overconfidence. One of the disorders similar to this in modern psychiatry is mania. It is based on this view point, the present study was conducted. Sidharthakadi Yoga is prepared in two forms-as gutika for nasya and as tablet for intake. The study was conducted on 20 subjects. Nasya with Sidharthakadi Gutika was done for 7 days and tablets were given for intake for 30 days (3 tabs twice daily after the course of nasya. Assessment was done before nasya, after 7 days of nasya and after 30 days of tablet intake. The assessment was done with Young Mania Rating Scale. It was observed that Sidharthakadi Yoga has significant effect in the management of mania without psychotic symptoms.

    To describe the nerve stimulator-guided sciatic-femoral nerve block in raptors undergoing surgical treatment of pododermatitis. Prospective clinical trial. Five captive raptors (Falco peregrinus) aged 6.7 ± 1.3 years. Anaesthesia was induced and maintained with isoflurane in oxygen. The sciatic-femoral nerve block was performed with 2% lidocaine (0.05 mL kg(-1) per nerve) as the sole intra-operative analgesic treatment. Intraoperative physiological variables were recorded every 10 minutes from endotracheal intubation until the end of anaesthesia. Assessment of intraoperative nociception was based on changes in physiological variables above baseline values, while evaluation of postoperative pain relied on species-specific behavioural indicators. The sciatic-femoral nerve block was feasible in raptors and the motor responses following electrical stimulation of both nerves were consistent with those reported in mammalian species. During surgery no rescue analgesia was required. The anaesthesia plane was stable and cardiorespiratory variables did not increase significantly in response to surgical stimulation. Iatrogenic complications, namely nerve damage and local anaesthetic toxicity, did not occur. Recovery was smooth and uneventful. The duration (mean ± SD) of the analgesic effect provided by the nerve block was 130 ± 20 minutes. The sciatic-femoral nerve block as described in dogs and rabbits can be performed in raptors as well. Further clinical trials with a control groups are required to better investigate the analgesic efficacy and the safety of this technique in raptors. © 2014 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    To analyse the patterns of facial nerve canal injury seen at temporal bone computed tomography (CT) in patients with traumatic facial nerve palsy and to correlate these with clinical manifestations and outcome. Thirty cases of temporal bone CT in 29 patients with traumatic facial nerve palsy were analyzed with regard to the patterns of facial nerve canal involvement. The patterns were correlated with clinical grade, the electroneurographic (ENoG) findings, and clinical outcome. For clinical grading, the House-Brackmann scale was used, as follows:grade I-IV, partial palsy group; grade V-VI, complete palsy group. The electroneuronographic findings were categorized as mild to moderate (below 90%) or severe (90% and over) degeneration. In 25 cases, the bony wall of the facial nerve canals was involved directly (direct finding): discontinuity of the bony wall was onted in 22 cases, bony spicules in ten, and bony wall displacement in five. Indirect findings were canal widening in nine cases and adjacent bone fracture in two. In one case, there were no direct or indirect findings. All cases in which there was complete palsy (n=8) showed one or more direct findings including spicules in six, while in the incomplete palsy group (n=22), 17 cases showed direct findings. In the severe degeneration group (n=13), on ENog, 12 cases demonstrated direct findings, including spicules in nine cases. In 24 patients, symptoms of facial palsy showed improvement at follow up evaluation. Four of the five patients in whom symptoms did not improve had spicules. Among ten patients with spicules, five underwent surgery and symptoms improved in four of these; among the five patients not operated on , symptoms did not improve in three. In most patients with facial palsy after temporal bone injury, temporal bone CT revealed direct or indirect facial nerve canal involvement, and in complete palsy or severe degeneration groups, there were direct findings in most cases. We believe that meticulous

    OBJECTIVE—To compare the efficacy, tolerability, and safety of three daily dosage regimens of oral piracetam in patients with progressive myoclonus epilepsy.
METHODS—Twenty patients (12 men, eight women), aged 17-43 years, with classical Unverricht-Lundborg disease were enrolled in a multicentre, randomised, double blind trial of crossover design in which the effects of daily doses of 9.6 g, 16.8 g, and 24 g piracetam, given in two divided doses, were compared with placebo. The crossover design was such that patients received placebo and two of the three dosage regimens of piracetam, each for two weeks, for a total treatment period of six weeks and thus without wash out between each treatment phase. The primary outcome measure was a sum score representing the adjusted total of the ratings of six components of a myoclonus rating scale in which stimulus sensitivity, motor impairment, functional disability, handwriting, and global assessments by investigators and patients were scored. Sequential clinical assessments were made by the same neurologist in the same environment at the same time of day.
RESULTS—Treatment with 24 g/day piracetam produced significant and clinically relevant improvement in the primary outcome measure of mean sum score (p=0.005) and in the means of its subtests of motor impairment (p=0.02), functional disability (p=0.003), and in global assessments by both investigator (p=0.002) and patient (p=0.01). Significant improvement in functional disability was also found with daily doses of 9.6 g and 16.8 g. The dose-effect relation was linear and significant. More patients showed clinically relevant improvement with the highest dosage and, in individual patients, increasing the dose improved response. Piracetam was well tolerated and adverse effects were few, mild, and transient.
CONCLUSIONS—This study provides further evidence that piracetam is an effective and safe medication in patients with Unverricht-Lundborg disease. In addition

    Isolated traumatic suprascapular nerve palsy without associated fracture is a rare occurrence. Localized segmental muscle atrophy limited to the supraspinatus and infraspinatus muscles associated with weakness in initiating abduction and in external rotation of the shoulder should suggest the diagnosis. Electromyography will confirm the diagnosis by excluding nerve root and brachial plexus involvement with denervation potentials limited to the supraspinatus and infraspinatus muscles.

    The hypoglossal nerve is a pure motor nerve. It provides motor control to the intrinsic and extrinsic tongue muscles thus being essential for normal tongue movement and coordination. In order to design a useful imaging approach and a working differential diagnosis in cases of hypoglossal nerve damage one has to have a good knowledge of the normal anatomy of the nerve trunk and its main branches. A successful imaging evaluation to hypoglossal diseases always requires high resolution studies due to the small size of the structures being studied. MRI is the preferred modality to directly visualize the nerve, while CT is superior in displaying the bony anatomy of the neurovascular foramina of the skull base. Also, while CT is only able to detect nerve pathology by indirect signs, such as bony expansion of the hypoglossal canal, MRI is able to visualize directly the causative pathological process as in the case of small tumors, or infectious/inflammatory processes affecting the nerve. The easiest way to approach the study of the hypoglossal nerve is to divide it in its main segments: intra-axial, cisternal, skull base and extracranial segment, tailoring the imaging technique to each anatomical area while bearing in mind the main disease entities affecting each segment.

    Sciatica may result from pathologies affecting the nerve both in its intraspinal and extraspinal course. In daily routine, the vast majority of cases are caused by herniation of the lumbar discs compressing the neural roots. Extraspinal causes of sciatic pain are usually underestimated and the imaging study may be completed after reporting the lumbar MRIs. However, early diagnosis of the exact etiology of sciatica is paramount for both relieving the symptoms and preventing any additional neur...

    In this report, the relationship of acoustic neuromas to the adjacent cranial nerves is discussed. On T{sub 1}-weighted images, the trigeminal nerve was detected in all 13 cases. Mild to marked compression of these nerves by the tumors was observed in eight cases. The extent of compression did not always correspond to the clinical symptoms. In four cases with a maximum tumor diameter of 2 cm or less, the 7th and 8th cranial nerves were identified. There was no facial palsy in these patients. Two patients with a tumor diameter of more than 2 cm also had no facial palsy. All patients, including those with small tumors, complained of hearing loss and/or tinnitus. While MR imaging has some limitations, it is an effective imaging modality for showing the relationship between tumors and nerves. (author).

    For artificial nerve conduits, great improvements have been achieved in mimicking the structures and components of autologous nerves. However, there are still some problems in conduit construction, especially in terms of mechanical properties, biomimetic surface tomography, electrical conductivity and sustained release of neurotrophic factors or cells. In this study, we designed and fabricated a novel electrospun nerve conduit enhanced by multi-walled carbon nanotubes (MWNTs) on the basis of a collagen/poly(ɛ-caprolactone) (collagen/PCL) fibrous scaffold. Our aim was to provide further knowledge about the mechanical effects and efficacy of MWNTs on nerve conduits as well as the biocompatibility and toxicology of MWNTs when applied in vivo. The results showed that as one component, carboxyl MWNTs could greatly alter the composite scaffold’s hydrophilicity, mechanical properties and degradability. The electrospun fibers enhanced by MWNTs could support Schwann cell adhesion and elongation as a substrate in vitro. In vivo animal studies demonstrated that the MWNT-enhanced collagen/PCL conduit could effectively promote nerve regeneration of sciatic nerve defect in rats and prevent muscle atrophy without invoking body rejection or serious chronic inflammation. All of these results showed that this MWNT-enhanced scaffold possesses good biocompatibility and MWNTs might be excellent candidates as engineered nanocarriers for further neurotrophic factor delivery research.

  13. High resolution computed tomography for peripheral facial nerve paralysis

    1987-01-01

    High resolution computer tomographic examinations of the petrous bones were performed on 19 patients with confirmed peripheral facial nerve paralysis. High resolution CT provides accurate information regarding the extent, and usually regarding the type, of pathological process; this can be accurately localised with a view to possible surgical treatments. The examination also differentiates this from idiopathic paresis, which showed no radiological changes. Destruction of the petrous bone, without facial nerve symptoms, makes early suitable treatment mandatory.

    OBJECTIVE: Recently, with the development of biological and artificial materials, the experimental and clinical studies on application of this new material-type nerve conduit for treatment of peripheral nerve defect have become the hotspot topics for professorial physicians.DATA SOURCES: Using the terms "nerve conduits, peripheral nerve, nerve regeneration and nerve transplantation" in English, we searched Pubmed database, which was published during January 2000 to June 2006, for the literatures related to repairing peripheral nerve defect with various materials. At the same time, we also searched Chinese Technical Scientific Periodical Database at the same time period by inputting" peripheral nerve defect, nerve repair, nerve regeneration and nerve graft" in Chinese.STUDY SELECTION: The materials were firstly selected, and literatures about study on various materials for repairing peripheral nerve defect and their full texts were also searched. Inclusive criteria: nerve conduits related animal experiments and clinical studies. Exclusive criteria: review or repetitive studies.DATA EXTRACTION: Seventy-nine relevant literatures were collected and 30 of them met inclusive criteria and were cited.DATA SYNTHESTS: Peripheral nerve defect, a commonly seen problem in clinic, is difficult to be solved. Autogenous nerve grafting is still the gold standard for repairing peripheral nerve defect, but because of its application limitation and possible complications, people studied nerve conduits to repair nerve defect. Nerve conduits consist of biological and artificial materials.CONCLUSION: There have been numerous reports about animal experimental and clinical studies of various nerve conduits, but nerve conduit, which is more ideal than autogenous nerve grafting, needs further clinical observation and investigation.

    The aim of the clinical trial was to evaluate the efficacy and safety of ProstateEZE Max, an orally dosed herbal preparation containing Cucurbita pepo, Epilobium parviflorum, lycopene, Pygeum africanum and Serenoa repens in the management of symptoms of medically diagnosed benign prostate hypertrophy (BPH). This was a short-term phase II randomized double-blind placebo controlled clinical trial. The trial was conducted on 57 otherwise healthy males aged 40-80 years that presented with medically diagnosed BPH. The trial participants were assigned to receive 3 months of treatment (1 capsule per day) with either the herbal preparation (n = 32) or a matched placebo capsule (n = 25). The primary outcome measure was the international prostate specific score (IPSS) measured at baseline, 1, 2 and 3 months. The secondary outcomes were the specific questions of the IPSS and day-time and night-time urinary frequency. There was a significant reduction in IPSS total median score in the active group of 36% as compared to 8% for the placebo group, during the 3-months intervention (p < 0.05). The day-time urinary frequency in the active group also showed a significant reduction over the 3-months intervention (7.0-5.9 times per day, a reduction of 15.6% compared to no significant reduction change for the placebo group (6.2-6.3 times per day) (p < 0.03). The night-time urinary frequency was also significantly reduced in the active group (2.9-1.8, 39.3% compared to placebo (2.8-2.6 times, 7%) (p < 0.004). The herbal preparation (ProstateEZE Max) was shown to be well tolerated and have a significant positive effect on physical symptoms of BPH when taken over 3 months, a clinically significant outcome in otherwise healthy men.

    Introduction In the general population, alcohol use disorder and depression more often occur together than any other combination of a mental illness with a substance use disorder. It is important to have a cost-effective intervention that is able to reach at-risk individuals in the early stages of developing alcohol use disorders and depression disorders. Methods and analysis This paper presents the protocol for a 3-arm multicentre randomised controlled trial (RCT) to test the efficacy and cost-effectiveness of the combined internet-based self-help intervention Take Care of You (TCOY) to reduce alcohol misuse and depression symptoms in comparison with a waiting list control group and a comparable intervention focusing on problematic alcohol use only. The active interventions consist of modules designed to reduce alcohol use, based on the principles of motivational interviewing and methods of cognitive behavioural therapy, together with additional modules in the combined study arm to reduce symptoms of depression. Data will be collected at baseline, as well as at 3 and 6 months postrandomisation. The primary outcome is the quantity of alcohol used in the past 7 days. A number of secondary outcome measures will be studied. These include the Centre of Epidemiologic Studies of Depression Scale (CES-D) and a combined measure with the criteria of values below the cut-off for severe alcohol use disorder and for CES-D. Data analysis will follow the intention-to-treat principle using (generalised) linear mixed models. In order to investigate the interventions’ cost-utility and cost-effectiveness, a full economic evaluation will be performed. Ethics and dissemination This RCT will be executed in compliance with the Helsinki Declaration and has been approved by 2 local Ethics Committees. Results will be reported at conferences and in peer-reviewed publications. Participant-friendly summaries of trial findings will be published on the TCOY websites. Trial registration

    Previous studies of nerve conduits have investigated numerous properties, such as conduit luminal structure and neurotrophic factor incorporation, for the regeneration of nerve defects. The present study used a poly(lactic-co-glycolic acid) (PLGA) copolymer to construct a three-dimensional (3D) bionic nerve conduit, with two channels and multiple microtubule lumens, and incorporating two neurotrophic factors, each with their own delivery system, as a novel environment for peripheral nerve regeneration. The efficacy of this conduit in repairing a 1.5 cm sciatic nerve defect was compared with PLGA-alone and PLGA-microfilament conduits, and autologous nerve transplantation. Results showed that compared with the other groups, the 3D bionic nerve conduit had the fastest nerve conduction velocity, largest electromyogram amplitude, and shortest electromyogram latency. In addition, the nerve fiber density, myelin sheath thickness and axon diameter were significantly increased, and the recovery rate of the triceps surae muscle wet weight was lowest. These findings suggest that 3D bionic nerve conduits can provide a suitable microenvironment for peripheral nerve regeneration to efficiently repair sciatic nerve defects.

    Highlights: •In the present study, we first elected ROIs corresponding to the proximal, medial, and distal levels of the lumbar foraminal zone. •The ROC analysis for FA values of distal nerves indicated a high level of reliability in the diagnosis of sciatica. •The declining trend of FA values from proximal to distal along the nerve tract may correlate with the disparity of axonal regeneration at different levels. •DTI is able to quantitatively evaluate compressed nerve roots and has a higher sensitivity and specificity for diagnosing sciatica than conventional MR imaging. •DTT enables visualization of abnormal nerve tracts, providing vivid anatomic information and probable localization of nerve compression. -- Abstract: Objective: To quantitatively evaluate nerve roots by measuring fractional anisotropy (FA) values in healthy volunteers and sciatica patients, visualize nerve roots by tractography, and compare the diagnostic efficacy between conventional magnetic resonance imaging (MRI) and DTI. Materials and methods: Seventy-five sciatica patients and thirty-six healthy volunteers underwent MR imaging using DTI. FA values for L5–S1 lumbar nerve roots were calculated at three levels from DTI images. Tractography was performed on L3–S1 nerve roots. ROC analysis was performed for FA values. Results: The lumbar nerve roots were visualized and FA values were calculated in all subjects. FA values decreased in compressed nerve roots and declined from proximal to distal along the compressed nerve tracts. Mean FA values were more sensitive and specific than MR imaging for differentiating compressed nerve roots, especially in the far lateral zone at distal nerves. Conclusions: DTI can quantitatively evaluate compressed nerve roots, and DTT enables visualization of abnormal nerve tracts, providing vivid anatomic information and localization of probable nerve compression. DTI has great potential utility for evaluating lumbar nerve compression in sciatica.

    Searching for effective drugs which are capable of promoting nerve regeneration after nerve injuries has gained extensive attention. Ginsenoside Rg1 (GRg1) is one of the bioactive compounds extracted from ginseng. GRg1 has been shown to be neuroprotective in many in vitro studies, which raises the possibility of using GRg1 as a neuroprotective agent after nerve injuries. However, such a possibility has never been tested in in vivo studies. The present study was designed to investigate the efficacy of GRg1 in promoting nerve regeneration after nerve crush injury in rats. All rats were randomly divided into four groups (n=8 in each group) after crush injury and were intraperitoneally administrated daily for 4 weeks with 1mg/kg, or 5mg/kg GRg1 (low or high dose GRg1 groups), or 100mug/kg mecobalamin or normal saline, respectively. The axonal regeneration was investigated by retrograde labeling and morphometric analysis. The motor functional recovery was evaluated by electrophysiological studies, behavioral tests and histological appearance of the target muscles. Our data showed that high dose GRg1 achieved better axonal regeneration and functional recovery than those achieved by low dose GRg1 and mecobalamin. The final outcome of low dose GRg1 and mecobalamin was similar in both morphological and functional items, which was significantly better than that in saline group. These findings show that GRg1 is capable of promoting nerve regeneration after nerve injuries, suggesting the possibility of developing GRg1 a neuroprotective drug for peripheral nerve repair applications.

    2013-01-01

    Following peripheral nerve compression, peripheral nerve microcirculation plays important roles in regulating the nerve microenvironment and neurotrophic substances, supplying blood and oxygen and maintaining neural conduction and axonal transport. This paper has retrospectively analyzed the articles published in the past 10 years that addressed the relationship between peripheral nerve compression and changes in intraneural microcirculation. In addition, we describe changes in different peripheral nerves, with the aim of providing help for further studies in peripheral nerve microcirculation and understanding its protective mechanism, and exploring new clinical methods for treating peripheral nerve compression from the perspective of neural microcirculation.

    Background/Aims Behavioural and psychological symptoms of dementia (BPSD) in Alzheimer's disease (AD) greatly increase caregiver burden. The abilities of donepezil and memantine to manage BPSD within their licensed indications in AD were compared. Methods A systematic review, random effects meta-analysis and Bucher indirect comparison were conducted. Results Six randomised controlled studies (4 donepezil and 2 memantine) reported use within the licensed indication and had Neuropsychiatric Inventory (NPI) data suitable for meta-analysis. BPSD showed significant improvement with donepezil compared with placebo [weighted mean difference (WMD) in NPI −3.51, 95% confidence interval (CI) −5.75, −1.27], whereas this was not the case for memantine (WMD −1.65, 95% CI −4.78, 1.49). WMD in NPI for donepezil versus memantine favoured donepezil but was not statistically significant (−1.86, 95% CI −5.71, 1.99; p = 0.34). Conclusion Within its licensed indication, donepezil is efficacious for the management of BPSD in AD compared with placebo. PMID:22163246

    2014-03-01

    In patients with primary cubital tunnel syndrome, we hypothesize that using a vascularized adipose sling to secure the ulnar nerve during anterior subcutaneous transposition will lead to improved patient outcomes. The adipose flap is designed to surround the ulnar nerve with a pliable, vascularized fat envelope, mimicking the natural fatty environment of peripheral nerves. This technique may offer advantages in securing the anteriorly transposed ulnar nerve and reducing instances of postoperative perineural scarring. Patients experience good functional outcomes; most experience resolution of symptoms.

    2004-01-01

    The current concept of recruiting residual function of an inadequate pelvic organ by electrostimulation involves stimulation of the sacral spinal nerves at the level of the sacral canal. The rationale for applying SNS to fecal incontinence was based on clinical observations of its effect on bowel habits and anorectal continence function in urologic patients (increased anorectal angulation and anal canal closure pressure) and on anatomic considerations: dissection demonstrated a dual peripheral nerve supply of the striated pelvic floor muscles that govern these functions. Because the sacral spinal nerve site is the most distal common location of this dual nerve supply, stimulating here can elicit both functions. Since the first application of SNS in fecal incontinence in 1994, this technique has been improved, the patient selection process modified, and the spectrum of indications expanded. At present SNS has been applied in more than 1300 patients with fecal incontinence limited.

    Patients presenting with facial pain often have ineffective pain relief with medical therapy. Cases refractory to medical management are frequently treated with surgical or minimally invasive procedures with variable success rates. We report on the use of ultrasound-guided trigeminal nerve block via the pterygopalatine fossa in patients following refractory medical and surgical treatment. To present the immediate and long-term efficacy of ultrasound-guided injections of local anesthetic and steroids in the pterygopalatine fossa in patients with unilateral facial pain that failed pharmacological and surgical interventions. Academic pain management center. Prospective case series. Fifteen patients were treated with ultrasound-guided trigeminal nerve block with local anesthetic and steroids placed into the pterygopalatine fossa. All patients achieved complete sensory analgesia to pin prick in the distribution of the V2 branch of the trigeminal nerve and 80% (12 out of 15) achieved complete sensory analgesia in V1, V2, V3 distribution within 15 minutes of the injection. All patients reported pain relief within 5 minutes of the injection. The majority of patients maintained pain relief throughout the 15 month study period. No patients experienced symptoms of local anesthetic toxicity or onset of new neurological sequelae. Prospective case series. We conclude that the use of ultrasound guidance for injectate delivery in the pterygopalatine fossa is a simple, free of radiation or magnetization, safe, and effective percutaneous procedure that provides sustained pain relief in trigeminal neuralgia or atypical facial pain patients who have failed previous medical interventions.

    Despite many pharmacological and psychosocial treatment options, schizophrenia remains a debilitating disorder. Thus, new treatment strategies rooted in the pathophysiology of the disorder are needed. Recently, vagus nerve stimulation (VNS) has been proposed as a potential treatment option for various neuropsychiatric disorders including schizophrenia. The objective of this study was to investigate for the first time the feasibility, safety and efficacy of transcutaneous VNS in stable schizophrenia. A bicentric randomized, sham-controlled, double-blind trial was conducted from 2010 to 2012. Twenty schizophrenia patients were randomly assigned to one of two treatment groups. The first group (active tVNS) received daily active stimulation of the left auricle for 26 weeks. The second group (sham tVNS) received daily sham stimulation for 12 weeks followed by 14 weeks of active stimulation. Primary outcome was defined as change in the Positive and Negative Symptom Scale total score between baseline and week 12. Various other secondary measures were assessed to investigate safety and efficacy. The intervention was well tolerated with no relevant adverse effects. We could not observe a statistically significant difference in the improvement of schizophrenia psychopathology during the observation period. Neither psychopathological and neurocognitive measures nor safety measures showed significant differences between study groups. Application of tVNS was well tolerated, but did not improve schizophrenia symptoms in our 26-week trial. While unsatisfactory compliance questions the feasibility of patient-controlled neurostimulation in schizophrenia, the overall pattern of symptom change might warrant further investigations in this population.

    BACKGROUND: Many diseases of the common peroneal nerve are a result of sciatic nerve injury. The present study addresses whether anatomical positioning of the sciatic nerve is responsible for these injuries. OBJECTIVE: To analyze anatomical causes of sciatic nerve and common peroneal nerve injury by studying the relationship between the sciatic nerve and piriformis. DESIGN, TIME AND SETTING: Observe and measure repeatedly. The experiment was conducted in the Department of Anatomy, Tianjin Medical College between January and June 2005. MATERIALS: Fifty-two adult cadavers 33 males and 19 females, with a total of 104 hemispheres, and fixed with formaldehyde, were provided by Tianjin Medical College and Tianjin Medical University. METHODS: A posterior cut was made from the lumbosacral region to the upper leg, fully exposing the piriformis and path of the sciatic nerve. MAIN OUTCOME MEASURES: (1) Anatomical characteristics of the tibial nerve and common peroneal nerve. (2) According to different areas where the sciatic nerve crosses the piriformis, the study was divided into two types--normal and abnormal. Normal is considered to be when the sciatic nerve passes through the infrapiriform foramen. Remaining pathways are considered to be abnormal. (3) Observe the relationship between the suprapiriform foramen, infrapiriform foramen, as well as the superior and inferior space of piriformis. RESULTS: (1) The nerve tract inside the common peroneal nerve is smaller and thinner, with less connective tissue than the tibial nerve. When pathological changes or variations of the piriformis, or over-abduction of the hip joint, occur, injury to the common peroneal nerve often arises due to blockage and compression. (2) A total of 76 hemispheres (73.08%) were normal, 28 were abnormal (26.92%). The piriformis can be injured, and the sciatic nerve can become compressed, when the hip joint undergoes intorsion, extorsion, or abduction. (3) The structures between the infrapiriform and

    To investigate the feasibility of the 3rd-6th intercostal nerve transfer to the suprascapular nerve for reconstruction of shoulder abduction. Fifteen thoracic walls (30 sides) were collected from cadavers. The 3rd-6th intercostal nerve length which can be dissected between the midaxillary line and midclavicular the transfer distance between the midaxillary line and midpoint of the clavicular bone (prepared point for neurotization) measured. In 30 sides of specimens, the 3rd and 4th intercostal nerves could be obtained between the midaxillary and midclavicular line, the available length of which was significantly greater than the transfer distance (P intercostal nerve and 16 sides of 6th intercostal nerve were covered by the costal cartilage before reaching the midclavicular line. The available length of the 5th intercostal nerve was similar to the transfer distance (P > 0.01), while the available the 6th intercostal nerve was significantly less than transfer distance (P intercostal nerve length and length (2 cm) of suprascapular nerve was significantly greater than the transfer distance (P intercostal nerve transfer to the suprascapular nerve for reconstruction of shoulder abduction. And 6th intercostal nerve, longer dissociated length may be required for direct coaptation or using a graft for nerve repair.

    Objective. Not fully understanding the type of axons activated during vagus nerve stimulation (VNS) is one of several factors that limit the clinical efficacy of VNS therapies. The main goal of this study was to characterize the electrical recruitment of both myelinated and unmyelinated fibers within the cervical vagus nerve. Approach. In anesthetized dogs, recording nerve cuff electrodes were implanted on the vagus nerve following surgical excision of the epineurium. Both the vagal electroneurogram (ENG) and laryngeal muscle activity were recorded in response to stimulation of the right vagus nerve. Main results. Desheathing the nerve significantly increased the signal-to-noise ratio of the ENG by 1.2 to 9.9 dB, depending on the nerve fiber type. Repeated VNS following nerve transection or neuromuscular block (1) enabled the characterization of A-fibers, two sub-types of B-fibers, and unmyelinated C-fibers, (2) confirmed the absence of stimulation-evoked reflex compound nerve action potentials in both the ipsilateral and contralateral vagus nerves, and (3) provided evidence of stimulus spillover into muscle tissue surrounding the stimulating electrode. Significance. Given the anatomical similarities between the canine and human vagus nerves, the results of this study provide a template for better understanding the nerve fiber recruitment patterns associated with VNS therapies.

  10. Regeneration of Optic Nerve

    Directory of Open Access Journals (Sweden)

    Kwok-Fai So

    2011-05-01

    Full Text Available The optic nerve is part of the central nervous system (CNS and has a structure similar to other CNS tracts. The axons that form the optic nerve originate in the ganglion cell layer of the retina and extend through the optic tract. As a tissue, the optic nerve has the same organization as the white matter of the brain in regard to its glia. There are three types of glial cells: Oligodendrocytes, astrocytes, and microglia. Little structural and functional regeneration of the CNS takes place spontaneously following injury in adult mammals. In contrast, the ability of the mammalian peripheral nervous system (PNS to regenerate axons after injury is well documented. A number of factors are involved in the lack of CNS regeneration, including: (i the response of neuronal cell bodies against the damage; (ii myelin-mediated inhibition by oligodendrocytes; (iii glial scarring, by astrocytes; (iv macrophage infiltration; and (v insufficient trophic factor support. The fundamental difference in the regenerative capacity between CNS and PNS neuronal cell bodies has been the subject of intensive research. In the CNS the target normally conveys a retrograde trophic signal to the cell body. CNS neurons die because of trophic deprivation. Damage to the optic nerve disconnects the neuronal cell body from its target-derived trophic peptides, leading to the death of retinal ganglion cells. Furthermore, the axontomized neurons become less responsive to the peptide trophic signals they do receive. On the other hand, adult PNS neurons are intrinsically responsive to neurotrophic factors and do not lose trophic responsiveness after axotomy. In this talk different strategies to promote optic-nerve regeneration in adult mammals are reviewed. Much work is still needed to resolve many issues. This is a very important area of neuroregeneration and neuroprotection, as currently there is no cure after traumatic optic nerve injury or retinal disease such as glaucoma, which

    In this study, we constructed tissue-engineered nerves with acel ular nerve al ografts in Sprague-Dawley rats, which were prepared using chemical detergents-enzymatic digestion and mechanical methods, in combination with bone marrow mesenchymal stem cel s of Wistar rats cultured in vitro, to repair 15 mm sciatic bone defects in Wistar rats. At postoperative 12 weeks, electrophysiological detection results showed that the conduction velocity of regenerated nerve after repair with tis-sue-engineered nerves was similar to that after autologous nerve grafting, and was higher than that after repair with acel ular nerve al ografts. Immunohistochemical staining revealed that motor endplates with acetylcholinesterase-positive nerve fibers were orderly arranged in the middle and superior parts of the gastrocnemius muscle;regenerated nerve tracts and sprouted branches were connected with motor endplates, as shown by acetylcholinesterase histochemistry combined with silver staining. The wet weight ratio of the tibialis anterior muscle at the affected contralateral hind limb was similar to the sciatic nerve after repair with autologous nerve grafts, and higher than that after repair with acel ular nerve al ografts. The hind limb motor function at the affected side was significantly improved, indicating that acel ular nerve al ografts combined with bone marrow me-senchymal stem cel bridging could promote functional recovery of rats with sciatic nerve defects.

    The feasibility of repairing dog sciatic nerve damage by using a biodegradable artificial tissue nerve graft enriched with neuroregenerating factors is investigated. The artificial nerve graft was implanted to a 30 mm gap of the sciatic nerve damage in 7 dogs. The dogs with the same nerve damage that were repaired by interposition of the autologous nerve or were given no treatment served as control group 1 or 2, respectively. The observations include gross and morphological observations, immune reaction, electrophysiological examination, fluorescence tracing of the neuron formation and the number of the neurons at the experimental sites, etc. Results showed that 6 months after the implantation of the graft, the regenerated nerve repaired the damage of the sciatic nerve without occurrence of rejection and obvious inflammatory reaction in all 7 dogs, and the function of the sciatic nerve recovered with the nerve conduction velocity of (23.91±11.35)m/s. The regenerated neurons and the forming of axon could be observed under an electron microscope. This proves that artificial tissue nerve graft transplantation can bridge the damaged nerve ends and promote the nerve regeneration.

    Background Processed nerve allografts offer a promising alternative to nerve autografts in the surgical management of peripheral nerve injuries where short deficits exist. Methods Three established models of acellular nerve allograft (cold-preserved, detergent-processed, and AxoGen® -processed nerve allografts) were compared to nerve isografts and silicone nerve guidance conduits in a 14 mm rat sciatic nerve defect. Results All acellular nerve grafts were superior to silicone nerve conduits in support of nerve regeneration. Detergent-processed allografts were similar to isografts at 6 weeks post-operatively, while AxoGen®-processed and cold-preserved allografts supported significantly fewer regenerating nerve fibers. Measurement of muscle force confirmed that detergent-processed allografts promoted isograft-equivalent levels of motor recovery 16 weeks post-operatively. All acellular allografts promoted greater amounts of motor recovery compared to silicone conduits. Conclusions These findings provide evidence that differential processing for removal of cellular constituents in preparing acellular nerve allografts affects recovery in vivo. PMID:21660979

    Magnetic resonance imaging (MRI) of the optic nerve was performed in 10 patients with multiple sclerosis (MS) using short inversion time inversion recovery (STIR) pulse sequences, and the results were compared with the visual evoked potentials (VEP). The 10 patients had optic neuritis in the chronic or remitting phase together with additional symptoms or signs allowing a diagnosis of clinically definite or probable MS. Sixteen optic nerves were clinically affected and 4 were unaffected. MRI was performed using a 0.5 tesla supeconducting unit, and multiple continuous 5 mm coronal and axial STIR images were obtained. A lesion was judged to be present if a focal or diffuse area of increased signal intensity was detectd in the optic nerve. In VEP, a delay in peak latency or no P 100 component was judged to be abnormal. With regard to the clinically affected optic nerves, MRI revealed a region of increased signal intensity in 14/16 (88%) and the VEP was abnormal in 16/16 (100%). In the clinically unaffected optic nerves, MRI revealed an increased signal intensity in 2/4 (50%). One of these nerves had an abnormal VEP and the other had a VEP latency at the upper limit of normal. The VEP was abnormal in 1/4 (25%). In the clinically affected optic nerves, the degree of loss of visual acuity was not associated with the longitudinal extent of the lesions shown by MRI. The mean length was 17.5 mm in optic nerves with a slight disturbance of visual acuity and 15.0 mm in nerves with severe visual loss. MRI using STIR pulse sequences was found to be almost as sensitive as VEP in detecting both clinically affected and unaffected optic nerve lesions in patients with MS, and was useful in visualizing the location or size of the lesions.

    Ultrasound of cranial nerves is a novel subdomain of neuromuscular ultrasound (NMUS) which may provide additional value in the assessment of cranial nerves in different neuromuscular disorders. Whilst NMUS of peripheral nerves has been studied, NMUS of cranial nerves is considered in its initial stage of research, thus, there is a need to summarize the research results achieved to date. Detailed scanning protocols, which assist in mastery of the techniques, are briefly mentioned in the few reference textbooks available in the field. This review article focuses on ultrasound scanning techniques of the 4 accessible cranial nerves: optic, facial, vagus and spinal accessory nerves. The relevant literatures and potential future applications are discussed.

    We report a previously undescribed complication associated with percutaneous maxillary nerve blockade. After the procedure, the patient reported an inability to close her ipsilateral eye (lagophthalmos). The patient had received 5 mL of 0.5% lidocaine for skin anesthesia. After needle placement was confirmed fluoroscopically, a combination of 80 mg methylprednisolone (2 mL) and 0.25% bupivacaine (3 mL) was administered. Symptoms resolved within 40 minutes. The likely cause was local anesthetic effect on the zygomatic branches of the facial nerve. When subcutaneous local anesthetic is given for maxillary block, smaller volumes should be considered. Doctors and patients should be aware of this complication, which may require treatment with artificial tears or patching of the eye to prevent corneal injury.

    Full Text Available Shoulder pain is a common problem with an estimated prevalence of 4% to 26%. 1 Pathology may originate from the neck, glenohumeral joint, acromioclavicular joint, rotator cuff, and other soft tissues around the shoulder girdle. Suprascapular nerve entrapment at spinoglenoid notch is rare but well documented. Kopell and Thompson 2 are credited with providing the first description of the suprascapular nerve entrapment syndrome . 3 This condition is largely underreported, meta - analysis revealed only 88 published reports on suprascapular nerve compression syndrome from 1959 through 2001. We report a case of suprascapular nerve compression at suprascapular foramen the cause of which was not the spinoglenoid cys t or any tumorous swelling like neuroma but a narrow canal at suprascapular foramen, the symptoms of which were relieved after surgical release of transverse scapular ligament.

    Sciatic nerve injuries associated with acetabular fractures can be post-traumatic, perioperative or postoperative. Late postoperative injury is very uncommon and can be due to heterotopic ossifications, muscular scarring, or implant migration. A case is presented of a patient with a previous transverse acetabular fracture treated with a reconstruction plate for the posterior column. After 17 years, she presented with progressive pain and motor deficit in the sciatic territory. Radiological and neurophysiological assessments were performed and the patient underwent surgical decompression of the sciatic nerve. A transection of the nerve was observed that was due to extended compression of one of the screws. At 4 years postoperatively, her pain had substantially diminished and the paresthesias in her leg had resolved. However, her motor symptoms did not improve. This case report could be relevant due to this uncommon delayed sciatic nerve injury due to prolonged hardware impingement. Copyright © 2014 SECOT. Published by Elsevier Espana. All rights reserved.

    Guyon's canal syndrome is an ulnar nerve entrapment at the wrist or palm that can cause motor, sensory or combined motor and sensory loss due to various factors . In this report, we presented a 66-year-old man admitted to our clinic with a history of intermittent pain in the left palm and numbness in 4th and 5th finger for two years. His neurological examination revealed a sensory impairment in the right fifth finger. Also, physical examination displayed a subcutaneous mobile soft tissue in ulnar side of the wrist. Electromyographic examination confirmed the diagnosis of type-1 Guyon's canal syndrome. Under axillary blockage, a lipoma compressing the ulnar nerve was excised totally and ulnar nerve was decompressed. The symptoms were improved after the surgery and patient was symptom free on 3rd postoperative week.

    Full Text Available Abstract Hemangiomas of the median nerve are very rare and, so far, only ten cases of intraneural hemangioma of this nerve have been reported in the literature. We present a case of 14-year-old girl who had a soft tissue mass in the region of the left wrist with signs and symptoms of carpal tunnel syndrome. Total removal of the mass was achieved using microsurgical epineural and interfasicular dissection. The symptoms were relieved completely, after this procedure, without any neurologic deficit. On follow-up two years later, no recurrence was observed. Whenever a child or young adult patient presents with CTS the possibility of a hemangioma involving the median nerve should be kept in mind in the differential diagnosis.

One month after the last cycle of R-CHOP, he developed a headache and numbness on the left side of his face. MRI revealed thickening of the left trigeminal nerve. He received one intrathecal injection of MTX and Ara-C, followed by systemic chemotherapy. After receiving intrathecal chemotherapy, his symptoms disappeared. Clinical response and MRI studies suggested secondary trigeminal nerve lymphoma. Two months later, our patient’s secondary trigeminal nerve lymphoma had progressed. Salvage whole brain irradiation (36 Gy with boost dose (50 Gy along the left trigeminal nerve was given. Unfortunately, our patient developed heart failure and expired during the radiotherapy session. In conclusion and specific to secondary central nervous system lymphoma (SCNSL, radiotherapy may benefit patients who fail to respond to systemic chemotherapy and palliative treatment. The results this report fail to support the role of radiotherapy in secondary trigeminal nerve lymphoma.

    Background: Radiosurgery is a well-established treatment modality for medically refractory trigeminal neuralgia. The exact mechanism of pain relief after radiosurgery is not clearly understood. Histopathology examination of the trigeminal nerve in humans after radiosurgery is rarely performed and has produced controversial results. Case Description: We report on a 45-year-old female who received radiosurgery treatment for trigeminal neuralgia by Cyberknife. A 6-mm portion of the cisternal segment of trigeminal nerve received a dose of 60 Gy. The clinical benefit started 10 days after therapy and continued for 8 months prior to a recurrence of her previous symptoms associated with mild background pain. She underwent microvascular decompression and partial sensory root sectioning. Atrophied trigeminal nerve rootlets were grossly noted intraoperatively under surgical microscope associated with changes in trigeminal nerve color to gray. A biopsy from the inferolateral surface of the nerve proximal to the midcisternal segment showed histological changes in the form of fibrosis and axonal degeneration. Conclusion: This case study supports the evidence of histological damage of the trigeminal nerve fibers after radiosurgery therapy. Whether or not the presence and degree of nerve damage correlate with the degree of clinical benefit and side effects are not revealed by this study and need to be explored in future studies.

    Facial palsy can be defined as a decrease in function of the facial nerve, the primary motor nerve of the facial muscles. When the facial palsy is peripheral, it affects both the superior and inferior areas of the face as opposed to central palsies, which affect only the inferior portion. The main cause of peripheral facial palsies is Bell's palsy, which remains a diagnosis of exclusion. The prognosis is good in most cases. In cases with significant cosmetic sequelae, a variety of surgical procedures are available (such as hypoglossal-facial anastomosis, temporalis myoplasty and Tenzel external canthopexy) to rehabilitate facial aesthetics and function.

    Ocular surface changes and blink abnormalities are well-established in Parkinson's disease. Blink rate may be influenced by corneal sub-basal nerve density, however, this relationship has not yet been investigated in Parkinson's disease. This case-control study examined the ocular surface in patients with moderately severe Parkinson's disease, including confocal microscopy of the cornea. Fifteen patients with moderately severe Parkinson's disease (modified Hoehn and Yahr grade 3 or 4) and fifteen control participants were recruited. Ophthalmic assessment included slit-lamp examination, blink rate assessment, central corneal aesthesiometry and in vivo corneal confocal microscopy. The effect of disease laterality was also investigated. Of the 15 patients with Parkinson's disease, ten were male and the mean age was 65.5±8.6years. The corneal sub-basal nerve plexus density was markedly reduced in patients with Parkinson's disease (7.56±2.4mm/mm(2)) compared with controls (15.91±2.6mm/mm(2)) (pParkinson's disease (0.79±1.2mBAR) and the control group (0.26±0.35mBAR), p=0.12. Sub-basal nerve density was not significantly different between the eye ipsilateral to the side of the body with most-severe motor symptoms, and the contralateral eye. There was a significant positive correlation between ACE-R scores and sub-basal corneal nerve density (R(2)=0.66, p=0.02). This is the first study to report a significant reduction in corneal sub-basal nerve density in Parkinson's disease and demonstrate an association with cognitive dysfunction. These results provide further evidence to support the involvement of the peripheral nervous system in Parkinson's disease, previously thought to be a central nervous system disorder.

    Full Text Available During routine dissection of a 60 years male cadaver, it was observed that the two divisions of sciatic nerve were separate in the gluteal region on both the sides with the tibial nerve passing below the piriformis and the common peroneal nerve piercing the piriformis muscle. The abnormal passage of the sciatic nerve (SN, the common peroneal nerve (CPN, and the tibial nerve (TN, either through the piriformis or below the superior gemellus may facilitate compression of these nerves. Knowledge of such patterns is also important for surgeons dealing with piriformis syndrome which affects 5-6% of patients referred for the treatment of back and leg pain. A high division may also account for frequent failures reported with the popliteal block. Keywords: eventration, piriformis muscle, piriformis syndrome, sciatic nerve

    Obese individuals have slowed conduction in the median nerve across the wrist, but the mechanism for this is not established. This case-control study of 27 obese subjects and 16 thin subjects was designed to test the hypothesis that obese individuals have higher carpal canal pressures and more median nerve swelling than thin individuals. All subjects were asymptomatic for hand symptoms, and had measurements of median and ulnar sensory nerve conduction in the nondominant hand, ultrasound measurement of the median nerve cross-sectional area proximal to the carpal canal, and carpal canal pressure measurement. There was no difference in age or gender ratio between the obese and thin groups. The median nerve cross-sectional area was equal in the obese and thin groups (9.3 mm2 vs. 9.4 mm2), as was the carpal canal pressure (16.2 mmHg vs. 15.5 mmHg, respectively). There was a strong correlation between median nerve conduction slowing across the wrist and median nerve cross-sectional area at the wrist (r = 0.55, P = 0.002). Obesity does not influence carpal canal pressure or the size of the median nerve at the wrist. However, there is a strong association between slowed median nerve conduction and increased nerve size which suggests endoneurial edema as a metabolic mechanism; the conduction slowing does not appear to be related to mechanical stress.

    In carpal tunnel syndrome (CTS), manual therapy interventions (MTI) reduce tissue adhesion and increase wrist mobility. We evaluated the efficacy of a MTI in relieving CTS signs and symptoms. Twenty-two CTS patients (pts) (41 hands) were treated with a MTI, consisting in 6 treatments (2/week for 3 weeks) of soft tissues of wrist and hands and of carpal bones. Pts were assessed for hand sensitivity, paresthesia, hand strength, hand and forearm pain, night awakening; Phalen test, thenar eminence hypotrophy and Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity Scale (SSS) and Functional Status Scale (FSS). Median nerve was studied by sensory nerve conduction velocity (SNCV) and distal motor latency (DML). CTS was scored as minimal, mild, medium, severe and extreme. We considered as control group the same pts assessed before treatment: at baseline (T0a) and after 12 weeks (T0b). Pts were evaluated at the end of treatment (T1) and after 24-week (T2) follow-up. At T0b, versus T0a, forearm pain and Phalen test positivity were increased and hand strength reduced (p < 0.05). BCTQ-SSS and BCTQ-FSS scores improved at T1 versus T0b (p < 0.05) with the amelioration maintained at T2. At T1, the number of pts with paresthesia, night awakening, hypoesthesia, Phalen test, hand strength reduction and hand sensitivity was reduced with the lacking of symptoms maintained at T2 (p < 0.05). No changes in SNCV, DML and CTS scoring were shown. MTI improved CTS signs and symptoms, with benefits maintained at follow-up. Thus, it may be valid as a conservative therapy.

    Plexiform neurofibromas are benign tumors of the peripheral nerve. Diagnosis may be challenging, if they present mimicking other peripheral nerve pathologies. We report the case of a patient who had severe foot pain, which progressively hampered her walking ability, erroneously attributed to recurrent Morton's neuroma. Diagnosis of plexiform neurofibroma of her right medial plantar nerve was made 15 years after the appearance of symptoms. Pain and function recovered after radical neurotomy of the medial plantar nerve. A correct diagnosis is an essential starting point in the treatment of neurofibromas and a misdiagnosis may lead to an inappropriate treatment.

    James C. Anderson

    2017-07-01

    Full Text Available IntroductionRestless legs syndrome (RLS is a prevalent sleep disorder affecting quality of life and is often comorbid with other neurological diseases, including peripheral neuropathy. The mechanisms related to RLS symptoms remain unclear, and treatment options are often aimed at symptom relief rather than etiology. RLS may present in distinct phenotypes often described as “primary” vs. “secondary” RLS. Secondary RLS is often associated with peripheral neuropathy. Nerve decompression surgery of the common and superficial fibular nerves is used to treat peripheral neuropathy. Anecdotally, surgeons sometimes report improved RLS symptoms following nerve decompression for peripheral neuropathy. The purpose of this retrospective analysis was to quantify the change in symptoms commonly associated with RLS using visual analog scales (VAS.MethodsForty-two patients completed VAS scales (0–10 for pain, burning, numbness, tingling, weakness, balance, tightness, aching, pulling, cramping, twitchy/jumpy, uneasy, creepy/crawly, and throbbing, both before and 15 weeks after surgical decompression.ResultsSubjects reported significant improvement among all VAS categories, except for “pulling” (P = 0.14. The change in VAS following surgery was negatively correlated with the pre-surgery VAS for both the summed VAS (r = −0.58, P < 0.001 and the individual VAS scores (all P < 0.01, such that patients who reported the worst symptoms before surgery exhibited relatively greater reductions in symptoms after surgery.ConclusionThis is the first study to suggest improvement in RLS symptoms following surgical decompression of the common and superficial fibular nerves. Further investigation is needed to quantify improvement using RLS-specific metrics and sleep quality assessments.

    Objectives To evaluate the efficacy and safety of certolizumab pegol (CZP) after 24 weeks in RAPID-axSpA (NCT01087762), an ongoing Phase 3 trial in patients with axial spondyloarthritis (axSpA), including patients with ankylosing spondylitis (AS) and non-radiographic axSpA (nr-axSpA). Methods Patients with active axSpA were randomised 1:1:1 to placebo, CZP 200 mg every 2 weeks (Q2W) or CZP 400 mg every 4 weeks (Q4W). In total 325 patients were randomised. Primary endpoint was ASAS20 (Assessment of SpondyloArthritis international Society 20) response at week 12. Secondary outcomes included change from baseline in Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Bath Ankylosing Spondylitis Metrology Index (BASMI) linear. Results Baseline disease activity was similar between AS and nr-axSpA. At week 12, ASAS20 response rates were significantly higher in CZP 200 mg Q2W and CZP 400 mg Q4W arms versus placebo (57.7 and 63.6 vs 38.3, p≤0.004). At week 24, combined CZP arms showed significant (p<0.001) differences in change from baseline versus placebo in BASFI (−2.28 vs −0.40), BASDAI (−3.05 vs −1.05), and BASMI (−0.52 vs −0.07). Improvements were observed as early as week 1. Similar improvements were reported with CZP versus placebo in both AS and nr-axSpA subpopulations. Adverse events were reported in 70.4% vs 62.6%, and serious adverse events in 4.7% vs 4.7% of All CZP versus placebo groups. No deaths or malignancies were reported. Conclusions CZP rapidly reduced the signs and symptoms of axSpA, with no new safety signals observed compared to the safety profile of CZP in RA. Similar improvements were observed across CZP dosing regimens, and in AS and nr-axSpA patients. PMID:24013647

    A diagnosis of diabetes mellitus types 1 or 2 doubles the odds of a comorbid depressive disorder. The combined diseases have a wide range of adverse outcomes, such as a lower quality of life, poorer diabetes outcomes and increased healthcare utilisation. Diabetes patients with depression can be treated effectively with psychotherapy, but access to psychological care is limited. In this study we will examine the efficacy and cost-effectiveness of a newly developed web-based intervention (GET.ON Mood Enhancer Diabetes) for people with diabetes and comorbid depressive symptoms. A two-arm randomised controlled trial will be conducted. Adults with diabetes (type 1 or type 2) with increased depression scores (> 22 on the German version of the Center for Epidemiological Studies Depression Scale (CES-D)) will be included. Eligible participants will be recruited through advertisement in diabetes patient journals and via a large-scale German health insurance company. The participants will be randomly assigned to either a 6-week minimally guided web-based self-help program or an online psychoeducation program on depression. The study will include 260 participants, which will enable us to detect a statistically significant difference with a group effect size of d = 0.35 at a power of 80% and a significance level of p = 0.05. The primary outcome measure will be the level of depression as assessed by the CES-D. The secondary outcome measures will be: diabetes-specific emotional distress, glycaemic control, self-management behaviour and the participants' satisfaction with the intervention. Online self-assessments will be collected at baseline and after a 2 months period, with additional follow-up measurements 6 and 12 months after randomisation. The data will be analysed on an intention-to-treat basis and per protocol. In addition, we will conduct an economic evaluation from a societal perspective. If this intervention is shown to be cost-effective, it has considerable potential

    Autologous nerve grafting is the current procedure used for repairing facial nerve gaps. As an alternative to this method, tissue engineering cell-based therapy using induced pluripotent stem cells, Schwann cells and bone marrow-derived mesenchymal stem cells has been proposed. However, these cells have major problems, including tumorigenesis in induced pluripotent stem cells and invasiveness and limited tissue associated with harvesting for the other cells. Here, we investigated the therapeutic potential of adipose-derived stem cells (ASCs), which can be harvested easily and repeatedly by a minimally invasive liposuction procedure. The ASCs had characteristics of mesenchymal tissue lineages and could differentiate into Schwann-like cells that were relatively simple to isolate and expand in culture. In an in vivo study, a silicone conduit containing undifferentiated ASCs, differentiated ASCs or Schwann cells were transplanted, embedded in a collagen gel and the efficacy of repair of a 7 mm-gap in the rat facial nerve examined. Morphometric quantification analysis of regenerated facial nerves after a regeneration period of 13 weeks showed that undifferentiated ASCs, differentiated ASCs, and Schwann cells had similar potential for nerve regeneration. Furthermore, the functional recovery of facial nerve regeneration using a rat facial palsy scoring system in the three groups was close to that in autologous nerve graft positive controls. These findings suggest that undifferentiated and differentiated ASCs may both have therapeutic potential in facial nerve regeneration as a source of Schwann cells in cell-based therapy performed as an alternative to autologous nerve grafts.

    There is a large scala of pathology affecting the vestibulocochlear nerve. Magnetic resonance imaging is the method of choice for the investigation of pathology of the vestibulocochlear nerve. Congenital pathology mainly consists of agenesis or hypoplasia of the vestibulocochlear nerve. Tumoral pathology affecting the vestibulocochlear nerve is most frequently located in the internal auditory canal or cerebellopontine angle. Schwannoma of the vestibulocochlear nerve is the most frequently found tumoral lesion followed by meningeoma, arachnoid cyst and epidermoid cyst. The most frequently encountered pathologies as well as some more rare entities are discussed in this chapter.

  10. α-Linolenic Acid, A Nutraceutical with Pleiotropic Properties That Targets Endogenous Neuroprotective Pathways to Protect against Organophosphate Nerve Agent-Induced Neuropathology

    Full Text Available α-Linolenic acid (ALA is a nutraceutical found in vegetable products such as flax and walnuts. The pleiotropic properties of ALA target endogenous neuroprotective and neurorestorative pathways in brain and involve the transcription factor nuclear factor kappa B (NF-κB, brain-derived neurotrophic factor (BDNF, a major neuroprotective protein in brain, and downstream signaling pathways likely mediated via activation of TrkB, the cognate receptor of BDNF. In this review, we discuss possible mechanisms of ALA efficacy against the highly toxic OP nerve agent soman. Organophosphate (OP nerve agents are highly toxic chemical warfare agents and a threat to military and civilian populations. Once considered only for battlefield use, these agents are now used by terrorists to inflict mass casualties. OP nerve agents inhibit the critical enzyme acetylcholinesterase (AChE that rapidly leads to a cholinergic crisis involving multiple organs. Status epilepticus results from the excessive accumulation of synaptic acetylcholine which in turn leads to the overactivation of muscarinic receptors; prolonged seizures cause the neuropathology and long-term consequences in survivors. Current countermeasures mitigate symptoms and signs as well as reduce brain damage, but must be given within minutes after exposure to OP nerve agents supporting interest in newer and more effective therapies. The pleiotropic properties of ALA result in a coordinated molecular and cellular program to restore neuronal networks and improve cognitive function in soman-exposed animals. Collectively, ALA should be brought to the clinic to treat the long-term consequences of nerve agents in survivors. ALA may be an effective therapy for other acute and chronic neurodegenerative disorders.

  11. Functional bowel symptoms and diet.

    It is well recognised that ingestion of food is a trigger for functional bowel symptoms, particularly those associated with irritable bowel syndrome (IBS). Patients often use manipulation of diet as a means of controlling symptoms. Despite description of multiple dietary methods, few have scientific backing or quality evidence of efficacy. One approach is to define how specific food components influence the pathophysiology of IBS and then rationally design dietary approaches. For example, short-chain poorly absorbed carbohydrates (fermentable oligo-, di- and mono-saccharides and polyols (FODMAP)) cause luminal distension, which is a major stimulus for the development of symptoms in patients with visceral hypersensitivity. By determining food content of FODMAP, a diet in which foods low in FODMAP are favoured over those high in FODMAP can be designed. Observational, comparative and randomised controlled treatment and rechallenge studies have shown that such an approach is efficacious in the majority of patients with IBS. The low FODMAP diet is now the primary dietary therapy for such patients. Similar approaches can be applied to other food components, including proteins (such as gluten), fats and natural bioactive food chemicals. Such approaches have suggestions of efficacy, but the evidence base remains underdeveloped. An additional and important consideration for any dietary therapy is its nutritional adequacy and potential adverse health effects. Dietary manipulation is now a key management strategy in patients with functional bowel symptoms. Future well-designed interventional studies will lead to refinement of dietary approaches taken and to a better understanding of their long-term safety.

    OBJECTIVE: To explore the effect of progesterone on peripheral nerve regeneration.DATA SOURCES: An online search of Medline and OVID databases was under taken to identify articles about progesterone and peripheral nerve regeneration published in English between January 1990 and June 2004 by using the keywords of "peripheral nerve, injury, progesterone, regeneration".STUDY SELECTION: The data were primarily screened, those correlated with progesterone and peripheral nerve regeneration were involved, and their original articles were further searched, the repetitive studies or reviews were excluded.DATA EXTRACTION: Totally 59 articles about progesterone and peripheral nerve regeneration were collected, and 26 of them were involved, the other 33 excluded ones were the repetitive studies or reviews.DATA SYNTHESIS: Recent researches found that certain amount of progesterone could be synthetized in peripheral nervous system, and the expression of progesterone receptor could be found in sensory neurons and Schwann cells. After combined with the receptor, endogenous and exogenous progesterone can accelerate the formation of peripheral nerve myelin sheath, also promote the axonal regeneration.CONCLUSION: Progesterone plays a role in protecting neurons, increasing the sensitivity of nerve tissue to nerve growth factor, and accelerating regeneration of nerve in peripheral nerve regeneration, which provides theoretical references for the treatment of demyelinated disease and nerve injury, as well as the prevention of neuroma, especially that the in vivo level of progesterone should be considered for the elderly people accompanied by neuropathy and patients with congenital luteal phase defect, which is of positive significance in guiding the treatment.

    Ulnar nerve tuberculoma is a rare case of tuberculous involvement of the peripheral nerve, which has attracted the attention of physicians. Here, we report the case of a patient with ulnar nerve tuberculoma. A 25-year-old patient presented progressive numbness on his left hand and forearm, and typical symptoms were not evident. The patient had no history of trauma or contact with any individuals with active tuberculosis. Exploratory surgery was performed and a granuloma-like lesion was found on the left ulnar nerve of the patient. The lesion was completely removed. We prepared hand-painted renderings for this rare disease for the first time, to the best of our knowledge. Histopathological examination of the specimen confirmed the presence of tuberculoma. After 1year of adequate antitubercular treatment, the patient recovered fully. Doctors need the most detailed radiographic information and histological results to confirm the diagnosis of this rare disease. At present, surgery is an effective way to resolve symptoms of ulnar nerve tuberculoma.

    To highlight the MRI characteristics of pathologically proven amyloidosis involving the peripheral nervous system (PNS) and determine the utility of MRI in directing targeted biopsy for aiding diagnosis. A retrospective study was performed for patients with pathologically proven PNS amyloidosis who also underwent MRI of the biopsied or excised nerve. MRI signal characteristics, nerve morphology, associated muscular denervation changes, and the presence of multifocal involvement were detailed. Pathology reports were reviewed to determine subtypes of amyloid. Charts were reviewed to gather patient demographics, neurological symptoms and radiologist interpretation. Four men and three women with a mean age of 62 ± 11 years (range 46-76) were identified. All patients had abnormal findings on EMG with mixed sensorimotor neuropathy. All lesions demonstrated diffuse multifocal neural involvement with T1 hypointensity, T2 hyperintensity, and variable enhancement on MRI. One lesion exhibited superimposed T2 hypointensity. Six of seven patients demonstrated associated muscular denervation changes. Peripheral nerve amyloidosis is rare, and the diagnosis is difficult because of insidious symptom onset, mixed sensorimotor neurologic deficits, and the potential for a wide variety of nerves affected. On MRI, peripheral nerve involvement is most commonly characterized by T1 hypointensity, T2 hyperintensity, variable enhancement, maintenance of the fascicular architecture with fusiform enlargement, multifocal involvement and muscular denervation changes. While this appearance mimics other inflammatory neuropathies, MRI can readily detect neural changes and direct-targeted biopsy, thus facilitating early diagnosis and appropriate management. (orig.)

    The sural nerve is a small sensory nerve innervating the lateral aspect of the ankle and foot. Clinical symptoms of pathology may present as atypical sensory changes in this region. We present the normal anatomy and ultrasound technique for examination of the sural nerve based on an anatomical dissection, as well as imaging in a normal volunteer. We also present a case series (n = 10) of different conditions of the sural nerve that we encountered based on a review of interesting cases from 4 institutions. The pathological conditions included neuropathy related to stripping or venous laser surgery, compression by abscess, Lyme disease, nerve tumors, traumatic transsection, and encasement by fibrous plaque and edema. Ultrasound with its exquisite resolution is the preferred imaging method for examining the sural nerve in patients with unexplained sensory changes at the lateral aspect of the ankle and foot.

  16. Recurrent laryngeal nerve pathology in spasmodic dysphonia.

    Since it was first described in 1871, spasmodic (spastic) dysphonia has been considered a disease of psychogenic origin. Unsupported theories of possible organic etiology have appeared sporadically in the literature. In 1976 sectioning of the recurrent laryngeal nerve for patients with this disease was reported with resultant improvement in voice production. This was attempted because the spasmodic dysphonic has, in effect, already compensated vocal cords bilaterally. It was reasoned, therefore, that if one of these was paralyzed the patient would immediately be converted to a state approximating that of well-compensated unilateral vocal cord paralysis which situation, as is well known, usually carries with it a fairly good voice. A controlled study to evaluate the efficacy of this surgical approach has been undertaken at the Cleveland Clinic during the past year. In an attempt to elucidate the possible organic etiology of spasmodic dysphonia, a section of nerve was removed in every case and examined by both light and electron microscopy. Special stains for myelin were also used on the light microscopy specimens. Demyelinization has been found in most of the cases examined by electron microscopy. Possible correlation between this disease entity and other cranial nerve syndromes of unknown etiology is noted. Such conditions as trigeminal neuralgia, glossopharyngeal neuralgia, belpharospasm, hemifacial spasm, and even possibly Bell's palsy may exhibit a similar etiology.

    OBJECTIVE Xiao et al. and other investigators have studied an intradural somatic-to-autonomic (e.g., L-5 to S3-4) nerve transfer as a method to create a reflex arc to allow bladder emptying in response to cutaneous stimulation (the Xiao procedure). In previous clinical studies of patients with spinal dysraphism who underwent the Xiao procedure, high success rates (70%-85%) were reported for the establishment of a "skin-CNS-bladder" reflex arc that allows spontaneous, controlled voiding in children with neurogenic bladder dysfunction. However, many of these studies did not use blinded observers, did not have control groups, and/or featured only limited follow-up durations. METHODS A randomized, prospective, double-blind trial was initiated in March 2009, enrolling children with myelomeningocele (MM), lipomyelomeningocele (LMM), and neurogenic bladder dysfunction who were scheduled for spinal cord detethering (DT) for the usual indications. At the time of DT, patients were randomized between 2 arms of the study: half of the patients underwent a standard spinal cord DT procedure alone (DT group) and half underwent DT as well as the Xiao procedure (DT+X group). Patients, families, and study investigators, all of whom were blinded to the surgical details, analyzed the patients' strength, sensory function, mobility, voiding, and urodynamic bladder function before surgery and at regular intervals during the 3-year follow-up. RESULTS Twenty patients were enrolled in the study: 10 underwent only DT and the other 10 underwent DT+X. The addition of the Xiao procedure to spinal cord DT resulted in longer operative times (p = 0.024) and a greater chance of wound infection (p = 0.03). Patients in both treatment arms could intermittently void or dribble small amounts of urine (Xiao procedure than in the patients who did not. No patient in either treatment arm was continent of urine before, during, or after the study. CONCLUSIONS Patients with MM and LMM who underwent the Xiao

    Peripheral facial nerve palsy (FNP) may (secondary FNP) or may not have a detectable cause (Bell's palsy). Three quarters of peripheral FNP are primary and one quarter secondary. The most prevalent causes of secondary FNP are systemic viral infections, trauma, surgery, diabetes, local infections, tumor, immunological disorders, or drugs. The diagnosis of FNP relies upon the presence of typical symptoms and signs, blood chemical investigations, cerebro-spinal-fluid-investigations, X-ray of the scull and mastoid, cerebral MRI, or nerve conduction studies. Bell's palsy may be diagnosed after exclusion of all secondary causes, but causes of secondary FNP and Bell's palsy may coexist. Treatment of secondary FNP is based on the therapy of the underlying disorder. Treatment of Bell's palsy is controversial due to the lack of large, randomized, controlled, prospective studies. There are indications that steroids or antiviral agents are beneficial but also studies, which show no beneficial effect. Additional measures include eye protection, physiotherapy, acupuncture, botulinum toxin, or possibly surgery. Prognosis of Bell's palsy is fair with complete recovery in about 80% of the cases, 15% experience some kind of permanent nerve damage and 5% remain with severe sequelae.

    Kawasaki disease (KD) is a multisystem disorder with varying clinical expression. We describe an instance of facial nerve paralysis in a patient with KD. A 5-month-old boy developed fever, irritability, and diarrhea, treated 8 days later with cefaclor and ibuprofen. Three days later a confluent, erythematous and papular rash appeared, his lips were reddened and swollen, and his white blood count and platelet count were 20,900/mm(3) and 558,000/mm(3), respectively. He was admitted to the hospital with a diagnosis of KD, and an echocardiogram showed a right coronary aneurysm. The patient then developed an acute, right-sided, facial nerve peripheral paralysis that resolved over the next 6 weeks. He was treated with intravenous immune globulin (IVIG) 2 g/kg and aspirin 100 mg/kg/day with improvement of signs and symptoms. This report documents facial nerve paralysis as an uncommon complication of KD and points out that it may be a marker of increased risk of cardiovascular disease in this disorder.

    The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell`s palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5 T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to a equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment. (orig.)

  1. Tissue engineering and peripheral nerve regeneration (III) -- Sciatic nerve regeneration with PDLLA nerve guide

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The biodegradation rate and biocompatibility of poly(d, l -lactide) (PDLLA) in vivo were evaluated. The aim of this study was to establish a nerve guide constructed by the PDLLA with 3-D microenvironment and to repair a 10 mm of sciatic nerve gap in rats. The process of the nerve regeneration was investigated by histological assessment, electrophysiological examination, and determination of wet weight recovery rate of the gastrocnemius muscle. After 3 weeks, the nerve guide had changed from a transparent to an opaque status. The conduit was degraded and absorbed partly and had lost their strength with breakage at the 9th week of postoperation. At the conclusion of 12 weeks, proximal and distal end of nerves were anastomosed by nerve regeneration and the conduit vanished completely. The results suggest that PDLLA conduits may serve for peripheral nerve regeneration and PDLLA is a sort of hopeful candidate for tissue engineering.

    Full Text Available Optic nerve hypoplasia (ONH is a congenital anomaly of the optic disc that might result in moderate to severe vision loss in children. With a vast number of cases now being reported, the rarity of ONH is obviously now refuted. The major aspects of ophthalmic evaluation of an infant with possible ONH are visual assessment, fundus examination, and visual electrophysiology. Characteristically, the disc is small, there is a peripapillary double-ring sign, vascular tortuosity, and thinning of the nerve fiber layer. A patient with ONH should be assessed for presence of neurologic, radiologic, and endocrine associations. There may be maternal associations like premature births, fetal alcohol syndrome, maternal diabetes. Systemic associations in the child include endocrine abnormalities, developmental delay, cerebral palsy, and seizures. Besides the hypoplastic optic nerve and chiasm, neuroimaging shows abnormalities in ventricles or white- or gray-matter development, septo-optic dysplasia, hydrocephalus, and corpus callosum abnormalities. There is a greater incidence of clinical neurologic abnormalities in patients with bilateral ONH (65% than patients with unilateral ONH. We present a review on the available literature on the same to urge caution in our clinical practice when dealing with patients with ONH. Fundus photography, ocular coherence tomography, visual field testing, color vision evaluation, neuroimaging, endocrinology consultation with or without genetic testing are helpful in the diagnosis and management of ONH.

    2017-09-01

    Physical therapists often assess and treat patients whose pain and disability stem from impaired mobility of the peripheral nervous system. Neural mobilization is a movement-based therapy, applied manually or via exercise. The nerve is mobilized relative to adjacent structures, with the aim of reducing symptoms through mechanisms that may be mechanical or neurophysiologic. A new systematic review published in the September 2017 issue of JOSPT includes 40 studies of neural mobilization in various neuromusculoskeletal conditions. The available evidence suggests that neural mobilization can be considered when treating certain nerve-related musculoskeletal conditions.

    Full Text Available BACKGROUND AND OBJECTIVES: Postoperative analgesia is crucial for early functional excise after total knee arthroplasty. To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. METHODS: 46 patients with ASA grade I-III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 patients, ultrasound and nerve stimulator guided continuous femoral nerve block were performed for analgesia (CFNB group; in 24 patients, epidural analgesia was done (PCEA group. The analgesic effects, side effects, articular recovery and complications were compared between two groups. RESULTS: At 6 h and 12 h after surgery, the knee pain score (VAS score during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of parecoxib used in CFNB patients was significantly reduced when compared with PCEA group. At 48 h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of nausea and vomiting in CFNB patients was significantly reduced when compared with PCEA group. CONCLUSION: Ultrasound and nerve stimulator guided continuous femoral nerve block provide better analgesia at 6 h and 12 h, demonstrated by RVAS and PVAS. The amount of parecoxib also reduces, the incidence of nausea and vomiting decreased, the influence on muscle strength is compromised and patients can perform ambulatory activity under this condition.

    The sensory symptoms due to lesions of the superficial branch of the radial nerve are usually limited to the dorsolateral area of the hand. We describe a 40-year-old woman who presented with numbness of the dorsomedial aspect of the right hand following arthroplasty of the wrist. Clinically, the sensory loss suggested a lesion of the dorsal branch of the ulnar nerve. However, nerve conduction studies showed that the sensory loss was due to a lesion of a branch of the superficial branch of the radial nerve. The patient had bilateral, anomalous innervation of the dorsum of the hand-the dorsal branch of the ulnar nerve could not be demonstrated with nerve conduction techniques and the superficial branch of the radial nerve innervated most of the dorsum of the hand. Antidromic stimulation of the dorsal branch of the ulnar nerve and superficial branch of the radial nerve with paired surface recording of sensory nerve action potentials from the dorsolateral (radial side) and dorsomedial (ulnar side) hand is useful for evaluating this anomaly. Our patient had two children, one of them with a similar anomaly. This suggests an autosomal dominant inheritance of the anomaly.

    Full Text Available Introduction Most children undergoing surgery can benefit from regional anesthetic techniques, either as the sole anesthetic regimen or, as usual in pediatric practice, in combination with general anesthesia. The use of peripheral nerve blocks (PNBs in pediatric anesthesia is an effective way to decrease the side-effects and complications associated with central blocks. In spite of their many advantages, including easy performance end efficacy, peripheral nerve blocks are still underused. Objective This article discusses a general approach to PNBs in children and provides data concerning the practice of this regional technique in different age groups. Methods Data from 1,650 procedures were prospectively collected during the period from March 1, 2007 to February 29, 2008. The type of PNB, if any, as well as the patient age were noted. Our patients were divided into four groups: 0-3 years, 4-7 years, 8-12 years and 13-18 years. Results During the investigated period, PNBs as a sole technique or in anesthetized children were performed in 7.45% of cases. Ilioingunal/iliohypogastric nerve block and penile block were the most common (70% of all PNBs distributed mainly among the children between 4-7 years of age (p<0.05. In older children, extremity PNBs predominate in regard to other types of blocks. PNBs are most frequently performed under general anesthesia (85%, so the perineural approach requires a safe technique to avoid nerve damage. Conclusion The observed differences in PNB usage seem to be related to patient age and correlate with common pathology and also with technical availability of PNB performance.

    The NerveSeeker is a new instrument for locating peripheral nerves. Like existing nerve stimulators, it is based on injecting current through the needle used for drug injection. However, the NerveSeeker was designed to automatically adjust the amplitude of the stimulating current pulses. It does this by feedback control to hold the level of response constant at a small but reliably detectable fraction of a maximal neural response. We report experimental tests of the NerveSeeker using an excised frog nerve in a transparent chamber, where we could observe the needle approach. A control voltage proportional to the stimulus magnitude was used to indicate the proximity of the needle tip to the nerve. The proximity was validated by direct measurement of the distance from the tip of the needle to the nerve. Parameters governing the performance of the NerveSeeker in tracking needle movement were analyzed. The following combined strategy was found effective: As the needle approached the nerve, the stimulus was reduced in proportion to the amplitude of the recorded response; as the needle moved away, the stimulus magnitude was incremented by a constant amount (enough to increase the neural response by approximately 1% of its maximum amplitude) after each stimulus that failed to elicit a neural response exceeding the criterion value. Stimulation throughout simulated penetrations was at a frequency of 10 Hz or higher to give more immediate guidance during insertion. Optimal settings for each control parameter were determined, reflecting both engineering and physiologic tradeoffs. With these settings, the device proved successful in localizing nerves, closely tracking needle movements at velocities as high as 2 mm/second. These experimental results suggest that clinical tests of the NerveSeeker would be appropriate.

    The multifidus muscle is the only paraspinal lumbar muscle that is innervated by a single nerve root. This study aimes to evaluate if the asymmetry of the multifidus muscle is related to the severity of compression of the nerve root or the duration of radiculopathy. MRI scans of 79 patients with symptomatic single level, unilateral, lumbar radiculopathy were reviewed for this retrospective case series with a nested case-control study. The cross-sectional area (CSA) of the multifidus muscle and the perpendicular distance of the multifidus to the lamina (MLD) were measured bilaterally by two radiologists and set into relation to the severity of nerve compression, duration of radiculopathy and probability of an indication for surgical decompression. In 67 recessal and 12 foraminal symptomatic nerve root compressions, neither the MLD ratio (severe 1.19 ± 0.55 vs less severe nerve compression: 1.12 ± 0.30, p = 0.664) nor the CSA ratio (severe 1 ± 0.16 vs less severe 0.98 ± 0.13, p = 0.577) nor the duration of symptoms significantly correlated with the degree of nerve compression. MR measurements of multifidus were not different in patients with (n = 20) and those without (n = 59) clinical muscle weakness in the extremity caused by nerve root compression. A MLD >1.5 was, however, associated with the probability of an indication for surgical decompression (OR 3, specificity 92 %, PPV 73 %). Asymmetry of the multifidus muscle correlates with neither the severity nor the duration of nerve root compression in the lumbar spine. Severe asymmetry with substantial multifidus atrophy seems associated with the probability of an indication of surgical decompression. (orig.)

    Despite the increasing use of ultrasound, electrical nerve stimulation is commonly used as the standard for both plexus and peripheral nerve blocks. Several recent randomized trials have contributed to a better understanding of physiological and clinical correlations. Traditionally used currents and impulse widths are better defined in relation to the distance between needle tip and nerves. Commercially available devices enable transcutaneous nerve stimulation and provide new opportunities for the detection of puncture sites and for training. The electrically ideal position of the needle usually is defined by motor responses which can not be interpreted without profound anatomical knowledge. For instance, interscalene blocks can be successful even after motor responses of deltoid or pectoral muscles. Infraclavicular blocks should be aimed at stimulation of the posterior fascicle (extension). In contrast to multiple single nerve blocks, axillary single-shot blocks more commonly result in incomplete anaesthesia. Blockade of the femoral nerve can be performed without any nerve stimulation if the fascia iliaca block is used. Independently of the various approaches to the sciatic nerve, inversion and plantar flexion are the best options for single-shot blocks. Further clinical trials are needed to define the advantages of stimulating catheters in continuous nerve blocks.

    Our group pioneered the study of nerve regeneration in China and has successfully developed human "acellular nerve grafts (ACNGs)". However, our clinical studies revealed that the effects of ACNGs for long and large nerve defects are far from satisfactory. To improve the efficacy of ACNGs, we combined Cartilage oligomeric matrix protein angiopoietin-1 (COMP-Ang1) with ACNGs in rat sciatic nerve injury models and observed the outcomes via angiographic, morphological, and functional analyses. Co-cultures of endothelial cells (ECs) and dorsal root ganglion neurons (DRGs) were also used to characterize the relationship between neovascularization and nerve regeneration. The results showed significant improvements in early neovascularization, nerve regeneration, and functional outcomes in vivo in the ACNG + COMP-Ang1 group. In vitro, neurite length, and density as well as the expression levels of neurofilament 68 (NF68) and phosphorylated-Tie-2 (p-Tie-2) significantly increased when ECs were co-cultured with DRGs using COMP-Ang1. p-Tie-2 expression dramatically decreased after treatment with a Tie-2 kinase inhibitor (S157701), which consequently decreased the level of NF68. COMP-Ang1 can be concluded to promote early neovascularization followed by brisk nerve regeneration, and the mechanism of this regeneration may involve the modulation of the p-Tie-2 and Tie-2 receptors on ECs. These findings demonstrate that ACNGs can be modified using COMP-Ang1 to improve their efficacy in repairing peripheral nerve defects in clinical trials.

    There are currently no available options to promote nerve regeneration through chronically denervated distal nerve stumps. Here we used a rat model of delayed nerve repair asking of prior insertion of side-to-side cross-bridges between a donor tibial (TIB) nerve and a recipient denervated common peroneal (CP) nerve stump ameliorates poor nerve regeneration. First, numbers of retrogradely-labelled TIB neurons that grew axons into the nerve stump within three months, increased with the size of the perineurial windows opened in the TIB and CP nerves. Equal numbers of donor TIB axons regenerated into CP stumps either side of the cross-bridges, not being affected by target neurotrophic effects, or by removing the perineurium to insert 5-9 cross-bridges. Second, CP nerve stumps were coapted three months after inserting 0-9 cross-bridges and the number of 1) CP neurons that regenerated their axons within three months or 2) CP motor nerves that reinnervated the extensor digitorum longus (EDL) muscle within five months was determined by counting and motor unit number estimation (MUNE), respectively. We found that three but not more cross-bridges promoted the regeneration of axons and reinnervation of EDL muscle by all the CP motoneurons as compared to only 33% regenerating their axons when no cross-bridges were inserted. The same 3-fold increase in sensory nerve regeneration was found. In conclusion, side-to-side cross-bridges ameliorate poor regeneration after delayed nerve repair possibly by sustaining the growth-permissive state of denervated nerve stumps. Such autografts may be used in human repair surgery to improve outcomes after unavoidable delays. PMID:26016986

    Acellular nerve allograft preserves the basilar membrane tube and extracellular matrix, which pro-motes selective regeneration of neural defects via bridging. In the present study, a Sprague Dawley rat sciatic nerve was utilized to prepare acellular nerve allografts through the use of the chemical extraction method. Subsequently, the allograft was transplanted into a 10-mm sciatic nerve defect in Wistar rats, while autologous nerve grafts from Wistar rats served as controls. Compared with autologous nerve grafts, the acellular nerve allografts induced a greater number of degenerated nerve fibers from sural nerves, as well as a reduced misconnect rate in motor fibers, fewer acetyl-choline esterase-positive sural nerves, and a greater number of carbonic anhydrase-positive senso-ry nerve fibers. Results demonstrated that the acellular nerve allograft exhibited significant neural selective regeneration in the process of bridging nerve defects.

    Parkinson disease (PD) is a neurodegenerative disease primarily characterized by cardinal motor manifestations and CNS pathology. Current drug therapies can often stabilize these cardinal motor symptoms, and attention has shifted to the other motor and nonmotor symptoms of PD that are resistant to drug therapy. Dysphagia in PD is perhaps the most important drug-resistant symptom because it leads to aspiration and pneumonia, the leading cause of death. Here, we present direct evidence for degeneration of the pharyngeal motor nerves in PD. We examined the cervical vagal nerve (cranial nerve X), pharyngeal branch of nerve X, and pharyngeal plexus innervating the pharyngeal muscles in 14 postmortem specimens, that is, from 10 patients with PD and 4 age-matched control subjects. Synucleinopathy in the pharyngeal nerves was detected using an immunohistochemical method for phosphorylated α-synuclein. Alpha-synuclein aggregates were revealed in nerve X and the pharyngeal branch of nerve X, and immunoreactive intramuscular nerve twigs and axon terminals within the neuromuscular junctions were identified in all of the PD patients but in none of the controls. These findings indicate that the motor nervous system of the pharynx is involved in the pathologic process of PD. Notably, PD patients who have had dysphagia had a higher density of α-synuclein aggregates in the pharyngeal nerves than those without dysphagia. These findings indicate that motor involvement of the pharynx in PD is one of the factors leading to oropharyngeal dysphagia commonly seen in PD patients.

    Early diagnosis of diabetic peripheral neuropathy is important for the successful treatment of diabetes mellitus. In the present study, we recruited 500 diabetic patients from the Fourth Afifl-iated Hospital of Kunming Medical University in China from June 2008 to September 2013: 221 cases showed symptoms of peripheral neuropathy (symptomatic group) and 279 cases had no symptoms of peripheral impairment (asymptomatic group). One hundred healthy control sub-jects were also recruited. Nerve conduction studies revealed that distal motor latency was longer, sensory nerve conduction velocity was slower, and sensory nerve action potential and amplitude of compound muscle action potential were signiifcantly lower in the median, ulnar, posterior tibial and common peroneal nerve in the diabetic groups compared with control subjects. More-over, the alterations were more obvious in patients with symptoms of peripheral neuropathy. Of the 500 diabetic patients, neural conduction abnormalities were detected in 358 cases (71.6%), among which impairment of the common peroneal nerve was most prominent. Sensory nerve abnormality was more obvious than motor nerve abnormality in the diabetic groups. The ampli-tude of sensory nerve action potential was the most sensitive measure of peripheral neuropathy. Our results reveal that varying degrees of nerve conduction changes are present in the early, as-ymptomatic stage of diabetic peripheral neuropathy.

    Damage to the peripheral nervous system is surprisingly common and occurs primarily from trauma or a complication of surgery. Although recovery of nerve function occurs in many mild injuries, outcomes are often unsatisfactory following severe trauma. Nerve repair and regeneration presents unique clinical challenges and opportunities, and substantial contributions can be made through the informed application of biomedical engineering strategies. This article reviews the clinical presentations and classification of nerve injuries, in addition to the state of the art for surgical decision-making and repair strategies. This discussion presents specific challenges that must be addressed to realistically improve the treatment of nerve injuries and promote widespread recovery. In particular, nerve defects a few centimeters in length use a sensory nerve autograft as the standard technique; however, this approach is limited by the availability of donor nerve and comorbidity associated with additional surgery. Moreover, we currently have an inadequate ability to noninvasively assess the degree of nerve injury and to track axonal regeneration. As a result, wait-and-see surgical decisions can lead to undesirable and less successful "delayed" repair procedures. In this fight for time, degeneration of the distal nerve support structure and target progresses, ultimately blunting complete functional recovery. Thus, the most pressing challenges in peripheral nerve repair include the development of tissue-engineered nerve grafts that match or exceed the performance of autografts, the ability to noninvasively assess nerve damage and track axonal regeneration, and approaches to maintain the efficacy of the distal pathway and targets during the regenerative process. Biomedical engineering strategies can address these issues to substantially contribute at both the basic and applied levels, improving surgical management and functional recovery following severe peripheral nerve injury.

    Many carpal tunnel syndrome (CTS) patients have symptoms in both the median and ulnar digits more frequently than in the median digits alone. This is possibly because of close anatomical contiguity of the carpal tunnel and Guyon's canal, and the high pressure may also affect the latter, causing indirect compression of ulnar nerve fibers. Thus, we evaluated the functional status of the ulnar nerve in patients with CTS in order to investigate the relationship between ulnar nerve impairment and sensory symptoms of the ulnar territory. Electrophysiological studies were conducted in CTS patients and healthy controls. CTS patients were divided into the mild/moderate group and severe group; they were further divided into the symptomatic and asymptomatic subgroups according to the sensory symptom of the fifth digit region. The findings suggest that CTS patients could have coexisting ulnar nerve wrist entrapments that might exacerbate the severity of CTS. Sensory impairment in the ulnar territory was observed more frequently in the mild/moderate stage of CTS, which is associated with ulnar nerve involvement. These findings also suggest that damage to the ulnar nerve fibers caused by compression forces in Guyon's canal may underlie the ulnar spread of symptoms in CTS.

    The repeated use of the nerve agent sarin against civilians in Syria in 2013 emphasizes the continuing threat by chemical warfare agents. Multiple studies demonstrated a limited efficacy of standard atropine-oxime treatment in nerve agent poisoning and called for the development of alternative and more effective treatment strategies. A novel approach is the use of stoichiometric or catalytic bioscavengers for detoxification of nerve agents in the systemic circulation prior to distribution into target tissues. Recent progress in the design of enzyme mutants with reversed stereo selectivity resulting in improved catalytic activity and their use in in vivo studies supports the concept of catalytic bioscavengers. Yet, further research is necessary to improve the catalytic activity, substrate spectrum and in vivo biological stability of enzyme mutants. The pros and cons of catalytic bioscavengers will be discussed in detail and future requirements for the development of catalytic bioscavengers will be proposed.

  8. Nerve conduction and electromyography studies.

    2012-07-01

    Nerve conduction studies (NCS) and electromyography (EMG), often shortened to 'EMGs', are a useful adjunct to clinical examination of the peripheral nervous system and striated skeletal muscle. NCS provide an efficient and rapid method of quantifying nerve conduction velocity (CV) and the amplitude of both sensory nerve action potentials (SNAPs) and compound motor action potentials (cMAPs). The CV reflects speed of propagation of action potentials, by saltatory conduction, along large myelinated axons in a peripheral nerve. The amplitude of SNAPs is in part determined by the number of axons in a sensory nerve, whilst amplitude of cMAPs reflects integrated function of the motor axons, neuromuscular junction and striated muscle. Repetitive nerve stimulation (RNS) can identify defects of neuromuscular junction (NMJ) transmission, pre- or post-synaptic. Needle EMG examination can detect myopathic changes in muscle and signs of denervation. Combinations of these procedures can establish if motor and/or sensory nerve cell bodies or peripheral nerves are damaged (e.g. motor neuronopathy, sensory ganglionopathy or neuropathy), and also indicate if the primary target is the axon or the myelin sheath (i.e. axonal or demyelinating neuropathies). The distribution of nerve damage can be determined as either generalised, multifocal (mononeuropathy multiplex) or focal. The latter often due to compression at the common entrapment sites (such as the carpal tunnel, Guyon's canal, cubital tunnel, radial groove, fibular head and tarsal tunnel, to name but a few of the reported hundred or so 'entrapment neuropathies').

  13. Pharmacological treatment of negative symptoms in schizophrenia.

    Science.gov (United States)

    Möller, Hans-Jürgen; Czobor, Pal

    2015-10-01

    Effective treatment of negative symptoms is one of the most important unmet needs in schizophrenic disorders. Because the evidence on current psychopharmacological treatments is unclear, the authors reviewed the findings published to date by searching PubMed with the keywords negative symptoms, antipsychotics, antidepressants, glutamatergic compounds, monotherapy and add-on therapy and identifying additional articles in the reference lists of the resulting publications. The findings presented here predominantly focus on results of meta-analyses. Evidence for efficacy of current psychopharmacological medications is difficult to assess because of methodological problems and inconsistent results. In general, the second-generation antipsychotics (SGAs) do not appear to have good efficacy in negative symptoms, although some show better efficacy than first-generation antipsychotics, some of which also demonstrated efficacy in negative symptoms. Specific trials on predominant persistent negative symptoms are rare and have been performed with only a few SGAs. More often, trials on somewhat persistent negative symptoms evaluate add-on strategies to ongoing antipsychotic treatment. Such trials, mostly on modern antidepressants, have demonstrated some efficacy. Several trials with small samples have evaluated add-on treatment with glutamatergic compounds, such as the naturally occurring amino acids glycine and D-serine and new pharmacological compounds. The results are highly inconsistent, although overall efficacy results appear to be positive. The unsatisfactory and inconsistent results can be partially explained by methodological problems. These problems need to be solved in the future, and the authors propose some possible solutions. Further research is required to identify effective treatment for the negative symptoms of schizophrenia.

    Full Text Available Schwannomas, neurilemmomas or neurinomas are benign nerve sheath tumors deriving from Schwann cells that occur in the head and neck region in 25-45% of cases 1 .About 10% of schwannoma that occur in the head and neck region generally originate from the vagus or sympathetic nervous system, those arising from C2 nerve root are extremely rare. 2 Preoperative imaging studies such as magnetic resonance imaging (MRI and computed tomography (CT are used to distinguish its location and origin. The treatment of schwannoma is surgical resection, with several surgical modalities have been introduced to preserve the neurological function. We present a rare case of Cervical nerve (C2-C3 root schwannoma of 70 years old male who presented with lateral neck swelling with no neurological deficit ,swelling which also had intervertebral part was removed successfully through neck incision with no post-operative neurological symptoms

  15. Development of Phantom Limb Pain after Femoral Nerve Block

    Directory of Open Access Journals (Sweden)

    Sadiah Siddiqui

    2014-01-01

    Full Text Available Historically, phantom limb pain (PLP develops in 50–80% of amputees and may arise within days following an amputation for reasons presently not well understood. Our case involves a 29-year-old male with previous surgical amputation who develops PLP after the performance of a femoral nerve block. Although there have been documented cases of reactivation of PLP in amputees after neuraxial technique, there have been no reported events associated with femoral nerve blockade. We base our discussion on the theory that symptoms of phantom limb pain are of neuropathic origin and attempt to elaborate the link between regional anesthesia and PLP. Further investigation and understanding of PLP itself will hopefully uncover a relationship between peripheral nerve blocks targeting an affected limb and the subsequent development of this phenomenon, allowing physicians to take appropriate steps in prevention and treatment.

    1997-11-01

    Purpose: Two new signs of lumbar nerve-root affection have been reported in recent years on the basis of MR examinations, namely: thickening in nerve roots; and contrast enhancement in nerve roots. The aim of this study was to assess contrast enhancement in nerve roots in a standardised way, and to evaluate the clinical significance of contrast enhancement and of nerve-root thickening in the symptomatic post-operative lumbar spine. Material and Methods: A total of 121 patients (who had previously been operated on for lumbar disc herniation) underwent 152 MR examinations, mainly on a 1.5 T system. Focal nerve-root enhancement was identified by visual assessment. Intradural enhancement was also quantified by pixel measurements that compared the affected nerve roots before and after contrast administration. Non-affected nerve roots were used as reference. Results: Enhanced nerve roots in the dural sac increased at least 40-50% in signal intensity after contrast administration compared to pre-contrast images and also compared to non-affected nerve roots. Intradural nerve-root enhancement was seen in 10% of the patients and focal enhancement in the root sleeve was seen in a further 26%. Nerve-root thickening was seen in 30%. Good correlation with clinical symptoms was found in 59% of the patients with intradural enhancement, in 84% with focal enhancement, and in 86% with nerve-root thickening. The combination of thickening and enhancement in the nerve root correlated with symptoms in 86% of the patients. Conclusion: Nerve-root enhancement (whether focal or intradural) and thickening in the nerve root are significant MR findings in the post-operative lumbar spine. In conbination with disc herniation or nerve-root displacement, these two signs may strengthen the indication for repeat surgery. However, root enhancement within 6 months of previous surgery may be a normal post-operative finding. (orig.).

    2004-01-01

    Objective: To evaluate the efficacy of axonal repair technique for treatment of peripheral nerve injury clinically.Methods: In 1998, the authors applied axonal repair technique to treat peripheral nerve injuries in 12 patients with 13 nerves. It consists of four steps, ie, stumps of the nerve being soaked in a modified Collins fluid, freezed,trimmed, and coapted with glue, making the injured nerve repaired at the axonal level.Results: The patients were followed up for an average of 13 months. Results showed that in 4 cases of first-stage contraiateral C7 transfer, regenerating axons reached to the sternoclavicular joint or axilla at 4 to 7 months, offering the timing for performing the second-stage contralateral C7 transfer. In 5 cases of accessory nerve transferred to the suprascapular nerve, the abduction of the shoulder was 40° on average. In the other 3 patients with four different nerves repaired, results were also satisfactory.Conclusions: This technique is promising in the treatment of peripheral nerve injury.

    The radial nerve neurodynamic test (ULNT2b), used to implicate symptoms arising from the radial nerve, is proposed to selectively increase strain of the nerve without increasing strain of adjacent tissue, though this has not been established. This study aimed to determine the upper limb position that results in: (1) the greatest tension of the radial nerve and (2) the greatest difference in tension between the radial nerve and the other two major nerves of the upper limb: median and ulnar. Tension (N) of the radial, median and ulnar nerves was measured simultaneously using three buckle force transducers during seven upper limb positions in the axilla of ten embalmed whole body human cadavers (n = 20 limbs). Repeated measures analysis of variance (ANOVA) with Bonferroni post-hoc tests determined differences in tension between nerves and between limb positions. A Composite position consisting of ULNT2b (scapular depression, shoulder internal rotation, elbow extension, forearm pronation, wrist flexion) with the addition of shoulder abduction 40° and extension 25°, wrist ulnar deviation and thumb flexion demonstrated significantly greater tension of the radial nerve than any other tested position (mean tension 11.32N; 95% CI 10.25, 12.29, p < 0.01), including ULNT2b (2.20N; 1.84, 2.57; p < 0.01). Additionally, the Composite position demonstrated the greatest difference in tension between the radial and median (mean difference 4.88N; 95% CI 3.16, 6.61; p < 0.01) and radial and ulnar nerves (9.26N, 7.54, 10.99; p < 0.01). This position constitutes a biomechanically plausible test to detect neuropathic pain related to the radial nerve.

    The optic nerve compartment syndrome is a pathological condition in which cerebrospinal fluid of the subarachnoid space surrounding the optic nerve is partly or totally segregated from the cerebrospinal fluid of the intracranial subarachnoid space, leading - inter alia - to an increase in the diameter of the optic nerve sheath. The pathogenesis of this condition remains unclear. We have observed clinically that optic nerve compartment syndrome often occurs in normal tension glaucoma patients with Flammer syndrome. To treat Flammer syndrome, some glaucoma patients received a low dose of a calcium channel blocker and we analysed whether this treatment also had an effect on the optic nerve compartment syndrome. We retrospectively analysed the data of 10 eyes of seven patients suffering from a combination of primary open angle glaucoma, optic nerve compartment syndrome, and Flammer syndrome. We included subjects who had eye socket echography before and after a few months of therapy with a calcium channel blocker. All patients received a low dose of a calcium channel blocker (nifedipine or amlodipine) to treat Flammer syndrome. As expected, the symptoms of Flammer syndrome were mitigated. To our surprise, the optic nerve compartment syndrome also improved in eight of the 10 eyes (80 %), but remained unchanged in the remainder. To some extent, the optic nerve compartment syndrome is related to the combination of primary open angle glaucoma and Flammer syndrome. On the basis of our results, we hypothesise that treatment of Flammer syndrome may also improve the optic nerve compartment syndrome. Georg Thieme Verlag KG Stuttgart · New York.

    The optic nerve is a sensitive central nervous system structure, which plays a critical role in many devastating pathological conditions. Several methods have been proposed in recent years to segment the optic nerve automatically, but progress toward full automation has been limited. Multi-atlas methods have been successful for brain segmentation, but their application to smaller anatomies remains relatively unexplored. Herein we evaluate a framework for robust and fully automated segmentation of the optic nerves, eye globes and muscles. We employ a robust registration procedure for accurate registrations, variable voxel resolution and image field-of-view. We demonstrate the efficacy of an optimal combination of SyN registration and a recently proposed label fusion algorithm (Non-local Spatial STAPLE) that accounts for small-scale errors in registration correspondence. On a dataset containing 30 highly varying computed tomography (CT) images of the human brain, the optimal registration and label fusion pipeline resulted in a median Dice similarity coefficient of 0.77, symmetric mean surface distance error of 0.55 mm, symmetric Hausdorff distance error of 3.33 mm for the optic nerves. Simultaneously, we demonstrate the robustness of the optimal algorithm by segmenting the optic nerve structure in 316 CT scans obtained from 182 subjects from a thyroid eye disease (TED) patient population.

    A novel, spatially selective method to stimulate cranial nerves has been proposed: contact free stimulation with optical radiation. The radiation source is an infrared pulsed laser. The Case Report is the first report ever that shows that optical stimulation of the auditory nerve is possible in the human. The ethical approach to conduct any measurements or tests in humans requires efficacy and safety studies in animals, which have been conducted in gerbils. This report represents the first step in a translational research project to initiate a paradigm shift in neural interfaces. A patient was selected who required surgical removal of a large meningioma angiomatum WHO I by a planned transcochlear approach. Prior to cochlear ablation by drilling and subsequent tumor resection, the cochlear nerve was stimulated with a pulsed infrared laser at low radiation energies. Stimulation with optical radiation evoked compound action potentials from the human auditory nerve. Stimulation of the auditory nerve with infrared laser pulses is possible in the human inner ear. The finding is an important step for translating results from animal experiments to human and furthers the development of a novel interface that uses optical radiation to stimulate neurons. Additional measurements are required to optimize the stimulation parameters.

    A rare cause of trigeminal neuralgia is malignant lymphoma which spread along the trigeminal nerve. We report a 79-year-old male presented with 4-month history of neuralgic pain in right cheek. He was diagnosed as classical trigeminal neuralgia. It had improved through medication of carbamazepine. Four months later, the dull pain unlike neuralgia complicated on the right cheeks, it was ineffective with the medication. Furthermore, diplopia and facial palsy as the other cranial nerve symptoms appeared. Gadolinium-enhanced magnetic resonance imaging (MRI) revealed contrast-enhanced mass lesion extend both external pterygoid muscle and brainstem through the swelling trigeminal nerve. The patient was pathological diagnosed of diffuse large B cell lymphoma by biopsy. Malignant lymphoma should be considered in the different diagnosis of cases with a minimal single cranial nerve symptom.

    For the diagnostics of nerve lesions an imaging method is necessary to visualize peripheral nerves and their surrounding structures for an etiological classification. Clinical neurological and electrophysiological investigations provide functional information about nerve lesions. The information provided by a standard magnetic resonance imaging (MRI) examination is inadequate for peripheral nerve diagnostics; however, MRI neurography is suitable but on the other hand a resource and time-consuming method. Using ultrasonography for peripheral nerve diagnostics. With ultrasonography reliable diagnostics of entrapment neuropathies and traumatic nerve lesions are possible. The use of ultrasonography for neuropathies shows that a differentiation between different forms is possible. Nerve ultrasonography is an established diagnostic tool. In addition to the clinical examination and clinical electrophysiology, structural information can be obtained, which results in a clear improvement in the diagnostics. Ultrasonography has become an integral part of the diagnostic work-up of peripheral nerve lesions in neurophysiological departments. Nerve ultrasonography is recommended for the diagnostic work-up of peripheral nerve lesions in addition to clinical and electrophysiological investigations. It should be used in the clinical work-up of entrapment neuropathies, traumatic nerve lesions and spacy-occupying lesions of nerves. (orig.)

    There are a variety of imaging modalities for evaluation of peripheral nerves. Of these, ultrasonography (US) is often underused. There are several advantages of this imaging modality, including its cost-effectiveness, time-efficient assessment of long segments of peripheral nerves, ability to perform dynamic maneuvers, lack of contraindications, portability, and noninvasiveness. It can provide diagnostic information that cannot be obtained by electrophysiologic or, in some cases, magnetic resonance imaging studies. Ideally, the neurosurgeon can use US as a diagnostic adjunct in the preoperative assessment of a patient with traumatic, neoplastic, infective, or compressive nerve injury. Perhaps its most unique use is in intraoperative surgical planning. In this article, a brief description of normal US nerve anatomy is presented followed by a description of the US appearance of peripheral nerve disease caused by trauma, tumor, infection, and entrapment.

  9. Optic Nerve Injury in a Patient with Chronic Allergic Conjunctivitis

    2014-01-01

    Full Text Available Manipulation of the optic nerve can lead to irreversible vision changes. We present a patient with a past medical history of skin allergy and allergic conjunctivitis (AC who presented with insidious unexplained unilateral vision loss. Physical exam revealed significant blepharospasm, mild lid edema, bulbar conjunctival hyperemia, afferent pupillary defect, and slight papillary hypertrophy. Slit lamp examination demonstrated superior and inferior conjunctival scarring as well as superior corneal scarring but no signs of external trauma or neurological damage were noted. Conjunctival cultures and cytologic evaluation demonstrated significant eosinophilic infiltration. Subsequent ophthalmoscopic examination revealed optic nerve atrophy. Upon further questioning, the patient admitted to vigorous itching of the affected eye for many months. Given the presenting symptoms, history, and negative ophthalmological workup, it was determined that the optic nerve atrophy was likely secondary to digital pressure from vigorous itching. Although AC can be a significant source of decreased vision via corneal ulceration, no reported cases have ever described AC-induced vision loss of this degree from vigorous itching and chronic pressure leading to optic nerve damage. Despite being self-limiting in nature, allergic conjunctivitis should be properly managed as extreme cases can result in mechanical compression of the optic nerve and compromise vision.

    Neurolysis with transposition of the nerve and nerve resection are commonly performed surgical procedures for appropriate managing Meralgia Paresthetica (MP). But long-term outcome of these two procedures are uncertain. This case-series study came to address follow-up results of these two surgical procedures for managing MP. We prospectively described 14 consecutive non-obese patients with clinical features of MP managed by one of the two studied procedures (nerve resection or neurolysis). Clinical variables were documented for each individual. The outcome of the surgery was assessed in follow-up visits within 18 months after the procedure. Nine patients were treated with neural resection procedure and others underwent neurolysis technique. In the group that underwent nerve resection, all patients experienced complete relief of unpleasant symptoms and MP did not recur in any of them during follow-up, while all patients who underwent neurolysis reported MP recurrence within 1 to 9 months after treatment initiation. Our results demonstrated that nerve resection is superior to neurolysis in terms of recurrence.

    Injuries to peripheral nerves are common and cause life-changing problems for patients along-side high social and health care costs for society. Current clinical treatment of peripheral nerve injuries predominantly relies on sacriifcing a section of nerve from elsewhere in the body to pro-vide a graft at the injury site. Much work has been done to develop a bioengineered nerve graft, precluding sacriifce of a functional nerve. Stem cells are prime candidates as accelerators of re-generation in these nerve grafts. This review examines the potential of adipose-derived stem cells to improve nerve repair assisted by bioengineered nerve grafts.

    2014-01-01

    Peripheral nerve injury impairs motor, sensory, and autonomic function, incurring substantial ifnancial costs and diminished quality of life. For large nerve gaps, proximal lesions, or chronic nerve injury, the prognosis for recovery is particularly poor, even with autografts, the current gold standard for treating small to moderate nerve gaps. In vivo elongation of intact proximal stumps towards the injured distal stumps of severed peripheral nerves may offer a promising new strategy to treat nerve injury. This review describes several nerve lengthening strategies, in-cluding a novel internal ifxator device that enables rapid and distal reconnection of proximal and distal nerve stumps.

    Background Inguinal hernia repair is associated with a high incidence of chronic postsurgical pain. This pain may be caused by injury to the iliohypogastric, ilioinguinal, or genitofemoral nerves. It is often difficult to identify the specific source of the pain, in part, because these nerves are derived from overlapping nerve roots and closely colocalize in the area of surgery. It is therefore technically difficult to selectively block these nerves individually proximal to the site of surgical injury. In particular, the genitofemoral nerve is retroperitoneal before entering the inguinal canal, a position that puts anterior approaches to the proximal nerve at risk of transgressing into the peritoneum. We report a computed tomography (CT)-guided transpsoas technique to selectively block the genitofemoral nerve for both diagnostic and therapeutic purposes while avoiding injury to the nearby ureter and intestines. Case A 39-year-old woman with chronic lancinating right groin pain after inguinal hernia repair underwent multiple pharmacologic interventions and invasive procedures without relief. Using CT and Stimuplex nerve stimulator guidance, the genitofemoral nerve was localized on the anterior surface of the psoas muscle and a diagnostic block with local anesthetic block was performed. The patient had immediate relief of her symptoms for 36 hours, confirming the diagnosis of genitofemoral neuralgia. She subsequently underwent CT-guided radiofrequency and phenol ablation of the genitofemoral nerve but has not achieved long-term analgesia. Conclusion CT-guided transpsoas genitofemoral nerve block is a viable option for safely and selectively blocking the genitofemoral nerve for diagnostic or therapeutic purposes proximal to injury caused by inguinal surgery.

    Diffusion-weighted images based on magnetic resonance reveal the microstructure of tissues by monitoring the random movement of water molecules. In this study, we investigated whether this new technique could visualize pathologic lesions on ulnar nerve in cubital tunnel. Six elbows in six healthy males without any symptoms and eleven elbows in ten patients with cubital tunnel syndrome underwent on diffusion-weighted MRI. No signal from the ulnar nerve was detected in normal subjects. Diffusion-weighted MRI revealed positive signals from the ulnar nerve in all of the eleven elbows with cubital tunnel syndrome. In contrast, conventional T2W-MRI revealed high signal intensity in eight elbows and low signal intensity in three elbows. Three elbows with low signal MRI showed normal nerve conduction velocity of the ulnar nerve. Diffusion-weighted MRI appears to be an attractive technique for diagnosis of cubital tunnel syndrome in its early stages which show normal electrophysiological and conventional MRI studies.

  3. Isolated trochlear nerve schwannoma presenting with diplopia: A case report and literature review

    Conclusion: Trochlear nerve schwannoma is a rare type of schwannoma and in almost all of the cases is diagnosed intraoperatively. There are three types of trochlear nerve schwannoma according to the classification proposed for trigeminal schwannoma: cisternal type—confined to the precavernous segment of the trochlear nerve; cistocavernous type—invading the cavernous sinus and the retroclival and retropetrosal cistern; cavernous type—located in the middle cranial fossa on the cavernous or paracavernous segment of the fourth cranial nerves, with or without cavernous sinus invasion. The cisternal type was the most common type encountered in previous studies. The clinical signs and symptoms of trochlear nerve schwannoma are similar to the trigeminal schwannoma and should be considered in the differential diagnosis of trigeminal schwannoma.

    Full Text Available Anterior transposition of the ulnar nerve is widely implemented for treatment of cubital tunnel ‎syndrome. However, preservation of the extrinsic blood supply of the ‎ulnar nerve may result in better clinical outcomes. Fourteen patients with cubital tunnel ‎syndrome, 11 ‎men and 3 women, were treated by anterior subcutaneous transposition of the ulnar nerve. The extrinsic blood supply of the ulnar nerve was ‎preserved. The average age at the time of operation was 33 years. The average follow-up period was 44 months. Post-operative outcome assessment by an independent examiner was based on the modified Bishop rating system. Nine patients had excellent or good outcomes. Five patients had a fair outcome. There ‎were no complications or recurrence of symptoms. Anterior subcutaneous ‎transposition of the vascularized ulnar nerve is an effective method of surgical ‎treatment for patients with cubital tunnel syndrome.

    Case report. To report a rare case of spinal cord infarction following therapeutic computed tomography-guided nerve root injection. Diagnostic and therapeutic image-guided nerve root injection is commonly performed in the management of low back pain and sciatica. The severe complication of spinal cord infarction has been reported in only 3 cases previously. Retrospective review of case records and imaging. A 71-year-old woman presented with symptoms and signs of left L2 nerve root compression. She was managed with computed tomography-guided left L2 nerve root injection using bupivacaine and triamcinolone and developed immediate bilateral sensory loss and paraplegia. Magnetic resonance imaging demonstrated diffuse hyperintensity within the distal thoracic cord and conus on T2-weighted images, consistent with spinal cord infarction. We report the fourth case of spinal cord infarction following nerve root injection. The severity of this complication warrants that it should be considered during patient consent for this procedure.

    Fibre structures represent a potential class of materials for the formation of synthetic nerve conduits due to their biomimicking architecture. Although the advantages of fibres in enhancing nerve regeneration have been demonstrated, in vivo evaluation of fibre size effect on nerve regeneration remains limited. In this study, we analyzed the effects of fibre diameter of electrospun conduits on peripheral nerve regeneration across a 15-mm critical defect gap in a rat sciatic nerve injury model. By using an electrospinning technique, fibrous conduits comprised of aligned electrospun poly (ε-caprolactone) (PCL) microfibers (981 ± 83 nm, Microfiber) or nanofibers (251 ± 32 nm, Nanofiber) were obtained. At three months post implantation, axons regenerated across the defect gap in all animals that received fibrous conduits. In contrast, complete nerve regeneration was not observed in the control group that received empty, non-porous PCL film conduits (Film). Nanofiber conduits resulted in significantly higher total number of myelinated axons and thicker myelin sheaths compared to Microfiber and Film conduits. Retrograde labeling revealed a significant increase in number of regenerated dorsal root ganglion sensory neurons in the presence of Nanofiber conduits (1.93 ± 0.71 × 10(3) vs. 0.98 ± 0.30 × 10(3) in Microfiber, p regeneration. These results could provide useful insights for future nerve guide designs.

    Acute lymphoblastic leukemia (ALL) is a haematological malignancy that can involve the central nervous system (CNS). Less than 10 % of patients with ALL have CNS involvement at presentation. The cranial nerve most commonly affected is cranial nerve VII although bilateral involvement is rare. Management and outcomes of these patients are not well understood. Moreover bilateral Bells palsy as a presenting symptom of ALL is extremely uncommon. We report a very unusual presentation of ALL with bilateral facial nerve palsy, and discuss the management strategies and outcomes for patients with ALL that present with cranial nerve palsies.

    2003-05-01

    Acute axonal polyneuropathy and Wernicke-Korsakoff encephalopathy developed simultaneously in three patients. Nerve conduction studies (NCS) detected markedly decreased compound muscle action potentials (CMAPs) and sensory nerve action potentials (SNAPs) with minimal conduction slowing; sympathetic skin responses (SSRs) were also notably decreased. Sural nerve biopsies showed only mild axonal degeneration with scattered myelin ovoid formation. The symptoms of neuropathy lessened within two weeks after an intravenous thiamine infusion. CMAPs, SNAPs, and SSRs also increased considerably. We suggest that this is a new type of peripheral nerve impairment: physiological conduction failure with minimal conduction delay due to thiamine deficiency.

    There is a strong demand for development of nerve guide conduit with prompt nerve regeneration potential for injury-induced nerve defect. Prior to study on nerve tissue engineering using Schwann cells or nerve stem cells, the effectiveness of photofabricated scaffolds based on photocurable gelatin was examined. This study describes the evaluation of in vivo nerve tissue regeneration potentials of three custom-designed and -fabricated prostheses (inner diameter, 1.2 mm; outer diameter, 2.4 mm; wall thickness, 0.60 mm; and length, 15 mm) made of photocured gelatin: a plain photocured gelatin tube (model I), a photocured gelatin tube packed with bioactive substances (laminin, fibronectin, and nerve growth factor) coimmobilized in a photocured gelatin rod (model II), and a photocured gelatin tube packed with bioactive substances coimmobilized in multifilament fibers (model III). These prostheses were implanted between the proximal and distal stumps 10 mm of the dissected right sciatic nerve of 70 adult male Lewis rats for up to 1 year. The highest regenerative potentials were found using the model III prosthesis, followed by the model II prosthesis. Markedly retarded neural regeneration was observed using the model I prosthesis. These were evaluated from the viewpoints of functional recovery, electrophysiological responses, and tissue morphological regeneration. The significance of the synergistic cooperative functions of multifilaments, which serve as a platform that provides contact guidance to direct longitudinal cell movement and tissue ingrowth and as a cell adhesive matrix with high surface area, and immobilized bioactive substances, which enhance nerve regeneration via biological stimulation, is discussed.

    Peripheral nerve gaps exceeding 1 cm require a bridging repair strategy. Clinical feasibility of autogenous nerve grafting is limited by donor site comorbidity. In this study we investigated neuroregenerative efficacy of autogenous vein grafts implanted with tissue fragments from distal nerve in combination with vascular endothelial growth factor (VEGF) or mesenchymal stem cells (MSCs) in repair of rat peripheral nerve defects. Six-groups of Sprague-Dawley rats (n = 8 each) were evaluated in the autogenous setting using a 1.6 cm long peroneal nerve defect: Empty vein graft (group 1), Nerve graft (group 2), Vein graft and nerve fragments (group 3), Vein graft and nerve fragments and blank microspheres (group 4), Vein graft and nerve fragments and VEGF microspheres (group 5), Vein graft and nerve fragments and MSCs (group 6). Nerve fragments were derived from distal segment. Walking track analysis, electrophysiology and nerve histomorphometry were performed for assessment. Peroneal function indices (PFI), electrophysiology (amplitude) and axon count results for group 2 were -9.12 ± 3.07, 12.81 ± 2.46 mV, and 1697.88 ± 166.18, whereas the results for group 5 were -9.35 ± 2.55, 12.68 ± 1.78, and 1566 ± 131.44, respectively. The assessment results did not reveal statistical difference between groups 2 and 5 (P > 0.05). The best outcomes were seen in group 2 and 5 followed by group 6. Compared to other groups, poorest outcomes were seen in group 1 (P ≤ 0.05). PFI, electrophysiology (amplitude) and axon count results for group 1 were -208.82 ± 110.69, 0.86 ± 0.52, and 444.50 ± 274.03, respectively. Vein conduits implanted with distal nerve-derived nerve fragments improved axonal regeneration. VEGF was superior to MSCs in facilitating nerve regeneration. © 2015 Wiley Periodicals, Inc.

    A man with multifocal acquired demyelinating sensory and motor neuropathy (MADSAM), or Lewis-Sumner syndrome, presented with a progressive left lumbosacral plexus lesion resembling a neurofibroma. After 7 years he developed a left ulnar nerve lesion with conduction block in its upper segment. Treatment with intravenous immunoglobulin improved the symptoms and signs of both lesions. We conclude that inflammatory neuropathy must be considered in the differential diagnosis of peripheral nerve tumors, and that unifocal lesions may precede multifocal involvement in MADSAM by several years. In addition, we discuss the clinical features in 9 patients attending a specialist peripheral nerve clinic and review the literature.

    BACKGROUND: Acute optic neuritis occurs with and without papillitis. The presence of papillitis has previously been thought to imply an anterior location of the neuritis, but imaging studies seeking to test this hypothesis have been inconclusive. METHODS: This prospective observational cohort study...... included 41 patients with unilateral optic neuritis and 19 healthy volunteers. All patients were evaluated and examined within 28 days of onset of symptoms.

    Full Text Available Otitis externa affects both children and adults. It is often treated with topical antibiotics, with good clinical outcomes. When a patient fails to respond to the treatment, otitis externa can progress to malignant otitis externa. The common symptoms of skull bone osteomyelitis include ear ache, facial pain, and cranial nerve palsies. However, an isolated cranial nerve is rare. Herein, we report a case of 54-year-old female who presented with left cranial nerve VI palsy due to skull base osteomyelitis which responded to antibiotic therapy.

In this paper, we aim to present a 52 year old female case with a postraumatic neuroma of the median nerve in the left wrist. Case Report: A 52-year-old female patient had accidental incised wound over her left wrist which was primarily sutured. She presented 6 months later with unrelieved pain and growing swelling at the wrist. USG showed solid mass of size 2×3 cms. Intraoperatively the mass was seen to arise from medial nerve and careful excision was done protecting the nerve. At one year follow up the patient is relived of her symptoms with no sensorimotor deficit. Conclusion: Post traumatic neuroma present as unrelieved pain and progressive swelling. A high index of suspicion should be kept in cases of wound that are primarily sutured over an area with superficial nerves. Careful excision of the lesion is very effective in relieving patients symptoms Keywords: Neuroma, wrist, median nerve, nerve ınjury.

    To evaluate the use of a palpebral spring, a dynamic facial reanimation technique, in the management of lagophthalmos and exposure keratopathy secondary to facial nerve palsy. A palpebral spring was placed in 29 eyelids of 28 patients with symptomatic facial nerve palsy. Preoperative and postoperative symptoms, upper eyelid margin to midpupil distance, lagophthalmos, and exposure keratopathy were evaluated. At an average of 83 months follow-up, preoperative symptoms improved or resolved in 26 (90%) eyes. The upper eyelid margin to midpupil distance decreased and lagophthalmos and exposure keratopathy significantly improved after palpebral spring placement (p lagophthalmos and exposure keratopathy in patients with facial nerve palsy who do not receive adequate relief from the static procedures of lower eyelid tightening and upper eyelid lowering. This technique significantly improved symptoms and signs in these patients while allowing some of the blink reflex.
