    ABSTRACT: There is an ample evidence that hypopigmentation of the skin along the Blaschko's lines is frequently associated with neurological disorders. Nowadays, the term "Hypomelanosis of Ito" (HI) is applied when, together with the cutaneous lesions, various and multisystem organs are involved. Among these, the most frequent are cerebral manifestations, such as cognitive delay and epileptic seizures. For this reason, hypomelanosis of Ito has been included in the group of neurocutaneous syndromes, neurologic manifestations being one of the most frequent. Epileptic seizures have been reported in patients with this disorder, but in a very few particular attention has been focused on the type and frequency of epilepsy and on the response to the treatment. Herein, we report on five patients with HI who showed episodes of epileptic seizures with onset in childhood, in absence of malformative anomalies except for the skin lesions. A survey on the frequency and types of epileptic seizures in HI children and in the literature is reported.

    ABSTRACT: It has been frequently reported that brain-derived neurotrophic factor (BDNF) plays an important role in the pathophysiology of major depressive disorder (MDD). Objective of the study was to investigate BDNF levels variations in MDD patients during antidepressant treatment with duloxetine. 30 MDD patients and 32 healthy controls were assessed using Hamilton Depression Scale (HAM-D) and monitored for BDNF plasma levels at baseline, week 6 and week 12 of duloxetine treatment (60 mg/day) and at baseline, respectively. According to early clinical response to duloxetine (defined at week 6 by reduction >50 % of baseline HAM-D score), MDD patients were distinguished in early responders (ER) and early non-responders (ENR), who reached clinical response at week 12. Laboratory analysis showed significant lower baseline BDNF levels among patients compared to controls. During duloxetine treatment, in ENR BDNF levels increased, reaching values not significantly different compared to controls, while in ER BDNF levels remained nearly unchanged. Lower baseline BDNF levels observed in patients possibly confirm an impairment of the NEI stress-adaptation system and neuroplasticity in depression, while BDNF increase and normalization observed only in ENR might suggest differential neurobiological backgrounds in ER vs. ENR within the depressive syndrome.

    ABSTRACT: In previous study, we have found the catechol-O-methyltransferase (COMT) Val158Met polymorphism may be associated with the risk of Parkinson’s disease (PD) in Asians, especially Japanese population. In this study, we further evaluated the associations of PD wearing-off susceptibility with COMT polymorphisms. We carried out a retrieval of studies and included the relevant studies which met the criteria. After the data were extracted, the Stata software 11.0 was used to analyse the genotype frequencies. A total of five studies were included. The pooled result indicated that genotype AA was significantly associated with the wearing-off risk of PD (AA vs. others: OR = 2.52, 95 % CI 1.21-5.26, P = 0.013; AA vs. GA: OR = 2.51, 95 % CI 1.18–5.34, P = 0.017; AA vs. GG: OR = 2.17, 95 % CI 1.09–4.33, P = 0.027). The results also showed allele A was correlated with PD wearing-off risk (A vs. G: OR = 1.95, 95 % CI 1.18–3.22, P = 0.009). In conclusion, this study suggested that Val158Met polymorphisms in COMT may increase the risk of wearing-off. Further studies with larger sample sizes are needed to confirm our results.

    ABSTRACT: Habituation is considered one of the most basic mechanisms of learning. Habituation deficit to several sensory stimulations has been defined as a trait of migraine brain and also observed in other disorders. On the other hand, analytic information processing style is characterized by the habit of continually evaluating stimuli and it has been associated with migraine. We investigated a possible correlation between lack of habituation of evoked visual potentials and analytic cognitive style in healthy subjects. According to Sternberg-Wagner self-assessment inventory, 15 healthy volunteers (HV) with high analytic score and 15 HV with high global score were recruited. Both groups underwent visual evoked potentials recordings after psychological evaluation. We observed significant lack of habituation in analytical individuals compared to global group. In conclusion, a reduced habituation of visual evoked potentials has been observed in analytic subjects. Our results suggest that further research should be undertaken regarding the relationship between analytic cognitive style and lack of habituation in both physiological and pathophysiological conditions.

    ABSTRACT: The aims of this study were to translate and investigate the interrater, test-retest reliability and internal consistency of the functional behavior profile (FBP) in an Italian population with multiple sclerosis. The Italian version of the FBP (FBP-I) was developed and the reliability of the final questionnaire was measured. A sample of 22 persons with clinically diagnosed multiple sclerosis was independently assessed by two raters. Interrater and test-retest reliability of the subscores and of the total score of the FBP-I were good to excellent. The internal consistency of the FBP-I was high. The FBP-I showed good psychometric properties and it can be used to assess functional status in Italian-speaking patients with multiple sclerosis.

    ABSTRACT: Mild hypothermia is an effective therapeutic strategy to improve poor neurological outcomes in patients following cardiac arrest (CA). However, the underlying mechanism remains unclear. The aim of the study was to evaluate the effect of mild hypothermia on intracellular autophagy and mitophagy in hippocampal neurons in a rat model of CA. CA was induced in Sprague-Dawley (SD) rats by asphyxia for 5 min. After successful resuscitation, the surviving rats were randomly divided into two groups, the normothermia (NT) group and the hypothermia (HT) group. Mild hypothermia (32 °C) was induced following CA for 4 h, and animals were rewarmed at a rate of 0.5 °C/h. Neurologic deficit scores (NDS) were used to determine the status of neurological function. Cytoplasmic and mitochondrial protein from the hippocampus was extracted, and the expression of LC3B-II/I and Parkin were measured as markers of intracellular autophagy and mitophagy, respectively. Of the 60 rats that underwent CA, 44 were successfully resuscitated (73 %), and 33 survived until the end of the experiment (55 %). Mild hypothermia maintained eumorphism of nuclear and mitochondrial structures and significantly improved NDS (p < 0.05). Expression of LC3B-II/I and Parkin in hippocampal nerve cells were significantly increased (p < 0.05) in the NT group relative to the control. Meanwhile, mild hypothermia reduced the level of LC3B-II/I and Parkin (p < 0.05) relative to the NT group. Mild hypothermia protected mitochondria and improved neurological function following CA and resuscitation after ischemia/reperfusion (I/R) injury, likely by reducing excessive autophagy and mitophagy in neurons.

    ABSTRACT: Neural tube defects (NTDs) are the most common and severe malformations of the central nervous system. The association of single nucleotide polymorphisms (SNPs) of the Frizzled 3 (FZD3) and Frizzled 6 (FZD6) genes and NTDs in the Han population of northern China was principally studied. One synonymous SNP (rs2241802) in FZD3 gene and three nonsynonymous SNPs (rs827528, rs3808553 and rs12549394) in FZD6 gene were analyzed by polymerase chain reaction (PCR) and sequencing methods in 135 NTD patients and 135 normal controls. The allele, genotype and haplotype frequencies were calculated and analyzed to examine the relationship between FZD3/FZD6 SNPs and NTDs. Both T allele and TT genotype frequencies of the FZD6 rs3808553 loci in the NTDs group were significantly higher than those in the controls, and children with T allele and TT genotype were associated with increased NTDs risk (OR = 1.575, 95 % CI 1.112-2.230, P = 0.010 and OR = 2.811, 95 % CI 1.325-5.967, P = 0.023, respectively). There were no differences among different genotypes or alleles in other three SNPs. Haplotypes A-G-C and A-T-C in FZD6 were found associated with NTDs in the case-control study (OR = 0.560, 95 % CI 0.378-0.830, P = 0.004 and OR = 1.670, 95 % CI 1.126-2.475, P = 0.011, respectively). The rs3808553 of FZD6 is obviously associated with NTDs in Han population of northern China. The TT genotype may increase risk for NTDs.

    ABSTRACT: The aim of the study was to assess the 90-day prognostic value of copeptin in a group of Chinese patients with acute intracerebral hemorrhage (ICH). In this study, all consecutive patients with first-ever ICH from 2010 to 2012 were recruited to participate in the study. On admission, plasma copeptin levels were measured by enzyme-linked immunosorbent assay. The Glasgow Coma Scale (GCS) and Hemphill ICH scores were assessed on admission blinded to plasma copeptin levels. For the assessment of functional outcome at 90 days, Modified Rankin Scale was used. During the study period, 271 patients were diagnosed as ICH and were included in the analysis. The median GCS score on admission was 11 points. Patients with an unfavorable outcomes and non-survivors had significantly increased plasma copeptin levels on admission (P < 0.001 for both). Copeptin was an independent prognostic marker of functional outcome and death [odds ratio 3.45 (95 % confidence intervals: 1.85-6.99) and 3.66 (2.42-8.28), respectively, P < 0.001 for both, adjusted for age, the hematoma volume and other predictors] in patients with ICH. In receiver operating characteristic curve analysis, copeptin could improve the Hemphill score in predicting 90-day functional outcome [area under the curve (AUC) of the combined model, 0.83; 95 % CI 0.74-0.90; P < 0.001] and mortality (AUC of the combined model, 0.88; 95 % CI 0.82-0.93; P < 0.001). In conclusion, our study suggests that copeptin levels are a useful tool to predict unfavorable functional outcome and mortality 90 days after ICH and have a potential to assist clinicians.

    ABSTRACT: We here in describe a case of hypereosinophilic syndrome (HES) with acute cerebral infarction in a watershed distribution with lesions of the carotid artery but no damage to the endocardium or myocardium. A 62-year-old Chinese man complained of left-sided hemiparesis. Brain MR showed multiple areas of acute ischemia. The eosinophil count was 4.84 × 10(9)/L, or 41.7 % of all white blood cells. Doppler ultrasound showed multiple medium-high echo plaques in the bilateral carotid bifurcation with reduction in diameter of 10-15 %. Transthoracic echocardiography was normal. A short course of glucocorticoids and aspirin were administered to the patient, and he was discharged with significant improvement of his neurological symptoms and eosinophil count. The patient refused to take prednisone thereafter; however, 6 months later, his eosinophil count was 1.57 × 10(9)/L, or 15.3 % of all white blood cells. Transthoracic echocardiography continued to be normal, but vascular ultrasound demonstrated many bilateral carotid low-medium echo plaques. This case describes a patient HES with acute cerebral infarction in a watershed distribution with lesions of the carotid artery but no cardiac damage. HES should be considered to be a cause of multiple cerebral infarctions.

    ABSTRACT: The aim was to evaluate whether patients with episodic migraine with (MA+) and without aura (MA-), during the interictal period of migraine would have an altered distensibility of the wall of cerebral arterial network and whether it would play a role in migraine headache. To evaluate the distensibility of the wall of cerebral arterial network, we measured the time-delay in milliseconds (ms) between the R-wave of an electrocardiogram and the arterial pulse wave of cerebral microcirculation (R-APWCMtd) on the frontal cortex detected by near-infrared spectroscopy (NIRS) in 10 patients with MA+ (age 39.5 ± 12.2 years), in 10 with MA- (age 40.3 ± 10.2 years), according to ICHD-3 criteria 2012, during the interictal period of migraine, and in 15 age-, sex- and height-matched healthy control subjects. The patients with migraine had a significantly longer R-APWCMtd than the control subjects F = 13.4, p < 0.001: MA+:+38.3 ms; MA-:+34.7 ms indicating an increased distensibility of the wall of cerebral arterial network. In multiple regression analysis, R-APWCMtd was significantly associated with migraine (R (2) = 0.50, p < 0.0001) but not with age, gender, height, migraine attack frequency and disease duration. The increased distensibility leads to an increased flow pulsatility into intracranial dural meningeal vessels that may lead to a mechanical stimulation of the nociceptors that innervate the dural vasculature. This condition may play a role in promoting the sensitization of trigeminovascular afferents and sterile inflammation within the dura mater that are fundamental to the pathogenesis of migraine headache.

    ABSTRACT: The etiology of amyotrophic lateral sclerosis (ALS) remains unknown, but existing data argue for a role of creatinine in ALS pathophysiology. Our aim is to clarify the correlation between serum creatinine and ALS in Chinese population. A total of 512 sporadic ALS (SALS) patients and 501 age- and gender-matched healthy controls were included. Revised ALS Functional Rating Scale (ALS-FRS-R) was used to assess the motor functional status of SALS patients. Survival analysis was performed using Kaplan-Meier method. Serum creatinine levels were significantly lower in SALS patients than in controls (p < 0.001). Patients with the second, the third and highest quartiles of creatinine levels had a significantly lower presence of ALS compared to those with the lowest quartile (p for trend <0.001). However, decreased presence of ALS was not found in the highest quartiles compared with the lowest quartiles in females. Sporadic ALS patients with different site of onset have similar serum creatinine levels, but underweight patients presented lower levels of serum creatinine. Patients with low serum creatinine levels are more likely to have severe motor impairment and low body mass index (BMI) values. This study demonstrates that SALS patients have lower serum creatinine levels than well-matched controls. Higher levels of serum creatinine are less likely to be associated with the presence of ALS in Chinese populations. Low serum creatinine levels may be related to severe motor impairment in SALS patients, after adjusting the confounding factor-BMI. However, serum creatinine has no deleterious impact on survival in ALS.
