Alterations in the balance of K-Na-2Cl cotransporter (NKCC1) and Na-Cl cotransporter (KCC2) activity may cause depolarizing effect of γ-aminobutyric Acid (GABA), and contribute to epileptogenesis in human temporal lobe epilepsy. NKCC1 facilitates accumulation of chloride inside neurons and favors depolarizing responses to GABA. In the current pilot study we provide the first documented look at efficacy of bumetanide, a specific NKCC1 antagonist, on reduction of seizure frequency in adult patients with temporal lobe epilepsy. According to our results, seizure frequency was reduced considerably in these patients. Furthermore, epileptiform discharges decreased in two of our patients. If the efficacy of bumetanide is proven in large scale studies, it can be used as a supplemental therapy in temporal lobe epilepsy. © 2012 International League Against Epilepsy.

Lavender is traditionally alleged to have a variety of therapeutic and curative properties, ranging from inducing relaxation to treating parasitic infections, burns, insect bites, and spasm. There is growing evidence suggesting that lavender oil may be an effective medicament in treatment of several neurological disorders. Several animal and human investigations suggest anxiolytic, mood stabilizer, sedative, analgesic, and anticonvulsive and neuroprotective properties for lavender. These studies raised the possibility of revival of lavender therapeutic efficacy in neurological disorders. In this paper, a survey on current experimental and clinical state of knowledge about the effect of lavender on the nervous system is given. © 2013 Peir Hossein Koulivand et al.

We have investigated whether poly(I:C) Toll-like receptor 3 (TLR3) and resiquimod Toll-like receptor 7 (TLR7) agonists can serve as vaccine adjuvants and promote the efficiency of therapeutic DNA vaccination against tumors expressing the human papilloma virus 16 (HPV-16) E7 protein. For this purpose, C57BL/6 mice were inoculated with 2 × 105 TC-1 cells, and they were then immunized with HPV-16 E7 DNA vaccine alone or with 50 μg of resiquimod or poly(I:C) individually. We found that poly(I:C) and resiquimod could induce more antigen-specific lymphocyte proliferation and cytolytic activity compared to vaccination with E7 DNA alone. While E7 DNA had no significant inhibitory effect on tumor growth, co-administration of poly(I:C) and resiquimod with E7 DNA induced significant tumor regression. Peripheral and local cytokine assays demonstrated that co-administration of poly(I:C) and resiquimod with E7 DNA induced circulating antigen-specific IFN-γ and nonspecific intratumoral IL-12. TLR3 and TLR7 agonists can be used to enhance the immune response to DNA vaccine immunogens. Taken together, these data indicate that combined vaccination with DNA encoding HPV-16 E7 plus TLR agonists provides a strategy for improving the efficacy of a vaccine as a possible immunotherapeutic strategy for cervical cancer. © 2014 Springer-Verlag Wien.

Study Design: Case-control. Purpose: Evaluate clinical and imaging factors which may predict the risk of failure of medical therapy in patients with lumbar disc herniation (LDH). Overview of Literature: LDH is a common cause of low back pain and radicular leg pain, with a generally favorable natural course. At present, however, it is not possible to identify patients who may be candidates for surgery in an early stage of their disease by means of clinical signs or diagnostic imaging criteria. Methods: We designed a study investigating patients with untreated low back pain to assess the predictive value of demographic, clinical or imaging findings in identifying patients who finally would meet the classic current criteria for surgery. Results: Among 134 patients, 80.6% were successfully treated with conservative therapy and 19.4% finally underwent surgery. Sex, occupation, involved root level, presence of Modic changes, osteophytes or annular tears were not significantly different between the 2 groups, while cerebrospinal fluid block, Pfirrmann's grade, location of herniation with regard to the midline, and type of herniation were significantly different. Anteroposterior fragment size was significantly higher and intervertebral foramen height and thecal sac diameters were significantly lower in the surgical group. Conclusions: Although it is strongly recommended to practice conservative management at first for patients with LDH symptoms, the results of this study shows that higher Pfirrmann's grade, more laterally located discs, extrusion and protrusion herniation types, and larger fragments could predict the risk of conservative treatment failure. This way, unnecessarily prolonged conservative management (beyond 4-8 weeks) may be precluded. © 2014 by Korean Society of Spine Surgery.

Methadone is known to exert modulatory effects on the immune system. We investigated the potential effects of methadone on infiltration of inflammatory cells into the spinal cord, as well as the proliferative and cytokine responses of T cells in MOG35-55-induced experimental autoimmune encephalomyelitis in mice. Methadone significantly suppressed clinical signs of the disease and level of inflammatory cytokines (p<0.05) produced by T cells. Moreover, invasion of inflammatory cells into the spinal cord was significantly decreased by methadone (p<0.05). Our data point to therapeutic effects of methadone and highlight the beneficial role of opioid receptor signaling in the context of autoimmune neuroinflammation. © 2012 Elsevier B.V.

Background: Migraine is a chronic and disabling disorder. Treatment of migraine often comprises of symptomatic (abortive) and preventive (prophylactic) treatment. The current drugs used in migraine prophylaxis include antidepressant drugs (Serotonin Reuptake Inhibitors, Tricyclic antidepressants), and anti-epileptic drugs (valproate, gabapentin, etc). Objective: The objective of our study was to assess the efficacy and tolerability of levetiracetam in adult migraine prophylaxis, compared to valproate and placebo. Materials and Methods: We conducted a prospective, randomized, placebo-controlled study. A total of 85 patients were randomized to receive levetiracetam 500 mg/d (n = 27), valproate 500 mg/d (n = 32) or placebo (n = 26). The patients were evaluated for treatment efficacy after 6 months. Efficacy was assessed as a more than 50% decrease in headache frequency. Results: In levetiracetam group, 17 (63.0%) patients experienced a more than 50% decrease in headache frequency, while this efficacy number was 21 (65.6%) for valproate group and 4 (15.4%) for placebo group. The difference was not statistically significant between levetiracetam and valproate, while it was significant when comparing either levetiracetam or valproate to placebo. Conclusion: Compared to placebo, levetiracetam offers improvement in headache frequency in patients with migraine. The efficacy of levetiracetam in migraine prophylaxis is comparable to currently used drugs such as valproate.

Malnutrition is a predictor of increased mortality in chronic hemodialysis (HD) patients. Various factors may contribute to malnutrition in these patients including energy and protein intake, inflammation, and comorbidity. To determine the importance of these factors in malnutrition of chronic HD patients, we studied 112 chronic HD patients in two centers was evaluated with the Dialysis Malnutrition Score (DMS) and anthropometric and biochemical indices. Seventy six (67.8%) patients were classified as malnourished. According to DMS score, poor protein intake (r= -0.34, P< 0.01), comorbidities (r= -0.24, P< 0.05), poor energy intake (r= - 0.18, P< 0.005), and inflammation (r= -0.16, P< 0.05) were significant predictors of malnutrition in descending order of importance. Multiple regression analysis showed that only poor protein intake was the explanatory variable of anthropometric measurements decline including body mass index, triceps skin fold thick-ness, mid arm circumference, mid arm muscle circumference, fat free mass, fat mass, albumin, creatinine and transferrine. None of the mentioned factors predicted the decrease of biochemical markers. We conclude that the frequency of malnutrition is high in our population and poor protein intake is the primary contributing factor for this condition. Therefore, providing enough protein may be a simple and effective way in preventing malnutrition in these patients.

Mozart's music has been shown to have promising effects on nervous system functions. In this study, the effects of Mozart's work on epilepsy were reviewed. Articles were obtained from a variety of sources. The results of 12 studies were extracted. Three different meta-analyses were performed to examine (i) the percentage of patients who had changes in their interictal epileptic discharges (IEDs) by music therapy; and the changes of IEDs (ii) during and (iii) after exposure to Mozart's music. Data analysis indicated that 84 % of patients listening to Mozart's music showed a significant decrease in IEDs. In addition, IEDs were decreased during (31.24 %) and after (23.74 %) listening to Mozart's compositions. A noteworthy response to music therapy in patients with a higher intelligence quotient, generalized or central discharges, and idiopathic epilepsy was demonstrated. The effect of Mozart's music on epilepsy seems to be significant. However, more randomized control studies are needed to determine its clinical efficacy. © 2013 Springer Science+Business Media New York.

Objective(s) The objective of this study was to evaluate the effect of cannabinoid on cortical spreading depression (CSD) in rat brain. Cannabis has been used for centuries for both symptomatic and prophylactic treatment of different types of headaches including migraine. CSD is believed to be a putative neuronal mechanism underlying migraine aura and subsequent pain. Materials and Methods The effects of Delta9-tetrahydrocannabinol (THC), as well as, cannabinoid CB1 and CB2 receptor agonists on CSD in rat neocortical slices were investigated. Furthermore, the effect of cannabinoid CB1 agonist was tested on field excitatory postsynaptic potentials (fEPSP) and long-term potentiation (LTP). Results HC (1-20 microM) dose dependently suppressed CSD amplitude, duration, and propagation velocity. Cannabinoid CB1 agonist, WIN 55,212-2 mesylate (1-10 microM), also significantly suppressed all characteristic features of CSD. However, cannabinoid CB2 agonist, JWH-133 (1-20 microM), did not affect CSD. FEPSP and induction of LTP were suppressed by application of WIN55212-2. Conclusion Suppression of CSD by activation of CB1 receptors points to the potential therapeutic effects of cannabinoids in migraine with aura. More research is needed before we know whether cannabinoids may be helpful in treating migraine pain.

Cortical spreading depression (CSD) plays an important role in migraine with aura. The caudate nucleus has crucial functional interactions with brain regions likely to be important in migraine. The aim of the present in vitro study was to investigate the effect of CSD on the neuronal activity of the caudate. Intracellular recording was performed in the head of the caudate nucleus alongside of extracellular recording in Wistar rat somatosensory cortex. CSD was induced by local KCl injection. Changes in the membrane potentials of the caudate neurons began 1.2. ±. 0.2. min after CSD. The neurons of the caudate nucleus depolarized first gradually and slightly then it depolarized abruptly at nearly the same point of time of the recovery of the cortical DC potential. Action potentials (APs) reappeared after the cortical DC shift returned to the baseline. Forty-five minutes after CSD, the caudate neurons showed lower frequency of APs and larger amplitude of depolarization prior to APs. The firing pattern of the caudate neurons evoked by injection of intracellular current pulses changed from slow adapting to fast adapting after CSD. Reduced neuronal activity in the caudate after CSD may be assumed to contribute to pain as well as changes in cognition and behavior in patients with migraine. © 2014 IBRO.
