Unlike CP caused by brain damage affecting muscle tone, movement and motor skills, equivocal report of different genes with varying loci as genetic malformation and genetic modulation by environmental factors have been the focus of attention in the aetiology of ASD. This study investigated levels of toxic metal (Pb) and macro elements (Ca and Mg) in blood of children with ASD and CP in Nigeria. 8 and 18 Children (aged 2 - 12 years) clinically screened for features of ASD and CP respectively by pediatric neurologist using DMS-IV classification along with 15 age-matched neurologically healthy ones as controls were recruited. Plasma levels of Ca, Mg and Pb were determined in the children using Induction Coupled Plasma Mass Spectroscopy (ICP-MS). Results were analyzed using students t-test. The gender difference was not significant in the children (P = 0.216) while developmental milestones’ abnormalities (stable neck, sitting, crawling and walking) was significantly prevalent among CP children relative to ASD and normal children (P= 0.003, 0.003, 0.003 and 0.000 respectively); however, abnormality in talking was common in ASD and CP relative to normal children (P = 0.000). There was significant difference in educational background of ASD and CP parents relative to those of normal children (P = 0.025). Mean plasma calcium and magnesium levels was significantly reduced in children with ASD (7.90 ± 0.17 mg/dl, 2.44 ± 0.07 mg/dl) and CP (7.26 ± 0.31 mg/dl, 2.42 ± 0.08 mg/dl) in comparison to the controls (8.97 ± 0.20 mg/dl and 3.26 ± 0.16 mg/dl); (P < 0.001; P < 0.000 and P < 0.002; P < 0.000) respectively.

Integrative approaches such as aromatherapy are used in addition to medications to improve sleep quality and reduce anxiety. Thus, PinetoninTM, a phytocomplex obtained from a blend of essential oils aims to aid in the symptoms of stress and anxiety. Methods: The cytotoxicity of PinetoninTM was evaluated MTT assay using fibroblasts and astrocytes showed reduction in the cell viability only at high concentrations. Evaluation of intracellular calcium and determination of residual glutamate in the supernatant of astrocyte cultures showed agonist action of dihydroxyphenylglycine (DHPG) increasing linearly the concentration of intracellular calcium and the glutamate levels in the supernatants of the cultures. On the other hand, cultures of astrocytes treated with PinetoninTM showed residual glutamate levels in the supernatants reducing proportionally, as well as, intracellular calcium reduction. The determination of salivary cortisol showed a significant reduction in salivary cortisol levels in the group that received PinetoninTM. The evaluation of the electroencephalogram in patients treated with PinetoninTM had a significant increase (P < 0.05) in the frequency (Hz) of the alpha and beta waves. Results: A reduction in dose-dependent cell viability was observed when compared to cultures of PinetoninTM treated fibroblasts with control culture. When PinetoninTM and linole are administered in astrocytic cells, there was a reduction of the intracellular concentration of Ca2+ against a control group treated with DHPG agonist. The evaluation of salivary cortisol demonstrated a reduction when the patient group was treated with PinetoninTM by purchasing the results against the group of patients treated with saline. Reinforcing the relaxed state of that group, alpha waves have been increased and reductions in beta waves. Conclusion: The results obtained after intranasal administration of PinetoninTM suggest that this phytocomplex can help reduce the symptoms of stress and the better quality of life.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"22 1","pages":"135-149"},"PeriodicalIF":0.0,"publicationDate":"2018-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85326054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study investigated sub-acute toxicity of Karuho poison on brain of Wistar albino rats. Laboratory based experimental study was conducted at Department of Pharmacology & Therapeutics, Makerere University College of Health Sciences. A total of 4 Karuho poisons (OMGKRP, DLNKRP, CHKRP and BHKRP) were screened for acute and sub-acute toxicity. Fifty animals, 10 in each group were daily dosed for 28 days with 1 mg, 5 mg, 20 mg and 5000 mg/kg bwt of OMGKRP (most active following screening) and normal saline for control group using OECD 407 and NIH 2011 guidelines. Behavioral changes were noted. Histopathological changes in brain regions were analyzed. Treated rats by OMGKRP, most active Karuho poison, were associated with sign of depression, piloerection and shortness of breath. Histopathological changes revealed moderate diffuse congestion and mononuclear inflammatory cells infiltration (plasma cells, lymphocytes and macrophage) in cerebral region with severe inflammation observed in meninges of cerebellum. OMGKRP poison induced inflammation of meninges of cerebellar region of brain.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"59 1","pages":"63-80"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76405495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors found to predict UTI include stroke severity, depressed consciousness level, increased post-void residual urine volume, and diabetes mellitus. Stroke severity appears to be the most important predictor of infection risk. We aimed to determine the risk factors associated with UTI after acute stroke, and its association with outcome. Subjects and Methods: This is prospective cohort study. We analysed clinical data of 100 patients with first ever ischemic stroke. We assessed risk factors for UTI, as well as clinical outcome. Results: Urinary tract infection was found in 72% of our subjects. On univariate analysis, patients with UTI were more likely to have had a more severe stroke, more likely to be catheterized and more likely to have a higher serum creatinine level. The multivariate analysis revealed that greater stroke severity was independently associated with increased risk of developing UTI. Greater stroke severity measured by CSS was independently associated with unfavorable outcome on discharge. Conclusion: UTI is common after acute stroke. It is associated with more severe stroke.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"51 1","pages":"94-104"},"PeriodicalIF":0.0,"publicationDate":"2018-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77611966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The syndrome of inappropriate anti-diuretic hormone (SIADH) and cerebral salt wasting (CSW) are characterized by hyponatremia and can be difficult to differentiate. Failure to accurately diagnose these conditions and implement the correct treatment results in an increased mortality risk, a longer length of stay in the hospital, and an increase in the cost of hospitalization. Objective: The purpose of this review is to summarize the key diagnostic findings in each disorder and to review the use of the fractional excretion of uric acid (FeUA) and the fractional excretion of phosphate as additional diagnostic measures to differentiate between SIADH and CSW. Observation: Publications from MEDLINE, CINAHL, and Google Scholar from 2009 through 2017 were reviewed. Articles were included if original data was presented and diagnosed either SIADH or CSW. Articles were excluded if they did not discuss diagnostic measures or were review articles. Results: Thirteen out of 51 publications met the inclusion criteria; four (31%) were clinica trials, seven (54%) were case reports, one (7.5%) was a prospective study and one (7.5%) was a retrospective-observational study. The populations studied, the etiologies causing hyponatremia, and diagnostic criteria used to distinguish between SIADH and CSW varied. Conclusion and Relevance: There is a need for consistent diagnostic criteria for SIADH and CSW. Based on current evidence, the use of FeUA and the fractional excretion of phosphate have consistently and accurately differentiated between SIADH and CSW.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"39 1","pages":"53-62"},"PeriodicalIF":0.0,"publicationDate":"2018-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86117440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Differences in neurophysiological responses were measured by N1-P2 Event-Related Potentials (ERP) in response to auditory changes in frequency and intensity. Reactions to daily sounds were measured by the hyperacusis questionnaire. Correlations between AASP, hyperacusis questionnaire, and ERP were measured. Results: The basic ability to detect a change in stimuli manifested in N1 waveform was not significantly different. However, participants with hypersensitivity presented a stronger P2 response and a higher hyperacusis score. Daily expressions of auditory hypersensitivity correlated (p = 0.05 - p = 0.01) with larger ERP responses. Conclusions: Auditory hypersensitivity as reflected in daily scenarios is evident in neurophysiological manifestations measured by ERPs. Understanding the relationship between the neural mechanisms of auditory hyper-ensitivity and its daily expressions, may optimize participation and wellbeing for people with hypersensitivity.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"7 1","pages":"29-45"},"PeriodicalIF":0.0,"publicationDate":"2018-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76506002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
