Abstract Background High epilepsy prevalence and incidence have been reported in areas with high onchocerciasis transmission. Recent findings suggest that proper community-directed treatment with ivermectin (CDTI) is potentially able to prevent onchocerciasis-associated epilepsy (OAE). We assessed the epilepsy prevalence and onchocerciasis transmission in two Nigerian villages following more than 20 years of CDTI. Methods A cross-sectional door-to-door survey was performed in two villages in the Imo River Basin reported to be mesoendomic for onchocerciasis (Umuoparaodu and Umuezeala). Individuals were screened for epilepsy using a validated 5-item questionnaire. Persons suspected to have epilepsy were examined by a neurologist or a physician with training in epilepsy for confirmation. Onchocerciasis was investigated via skin snip microscopy and rapid diagnostic tests for Ov16 antibodies. Results were compared with previous findings from the Imo river basin. Results A total of 843 individuals from 257 households in the two villages were encountered. We detected four persons with epilepsy (PWE) giving a crude epilepsy prevalence of 0.5%. This finding differs from observations reported 14 years ago which showed an epilepsy prevalence of 2.8% in the neighbouring village of Umulolo (P = 0.0001), and 1.2% from 13 villages in the Imo river basin (P = 0.07). The seroprevalence of Ov16 antibodies was found to be 0%. Only 4.6% of skin snips were positive compared to 26.8% in previous surveys (P

The visual system is commonly involved in MS and provides an ideal model to study TSD given its well-defined structure. TSD may occur in an anterograde direction (optic neuropathy causing degeneration in the posterior visual pathway including the optic radiations and occipital gray matter) and/or retrograde direction (posterior visual pathway lesions causing retinal degeneration). In the current review, we discuss evidence supporting the presence of anterograde and retrograde TSD in the visual system in MS.Keywords: multiple sclerosis, optic neuritis, transsynaptic degeneration, neurodegeneration, optical coherence tomography

Background The use of anti-epileptic drugs (AEDs) in women of childbearing age (WCBA) necessitates careful counselling regarding reproductive-related issues. Aim (i) To compare documentation of appropriate counselling regarding reproductive-related issues in WCBA prescribed AEDs for non-epilepsy vs. epilepsy indications, and (ii) to examine whether the frequency of counselling improved after introduction of 'standardized typed advice'. Design Retrospective audit and quality assessment and improvement programme. Methods We analysed medical records of all WCBA prescribed gabapentin, pregabalin, topiramate, valproate or carbamazepine by a general neurology clinical service before (Study period A) and after (Study period B) introduction of standardized typed passages regarding potential teratogenicity ± interactions with hormonal contraception at a university teaching hospital. The χ2 test or the Fisher's exact test was employed, as appropriate. Results In WCBA prescribed AEDs for non-epilepsy indications, documentation of appropriate counselling regarding potential teratogenicity improved from 49% (17/35 patients) in Period A to 79% (27/34 patients) in Period B (P  = 0.008). The frequency of counselling regarding teratogenicity was higher in patients prescribed AEDs for epilepsy compared with non-epilepsy indications in Study period A (100% vs. 49%, P  = 0.002), but was no longer significantly different in Study period B (86% vs. 79%, P  = 0.64). Documentation of counselling regarding potential interaction of enzyme-inducing AEDs with hormonal contraception did not significantly change between study periods. Conclusion Significant improvements in documentation regarding potential teratogenicity of AEDs prescribed for non-epilepsy indications can be achieved by introducing standardized, typed passages copied to patients. Such a practice change is practical and widely applicable to neurological and non-neurological practice worldwide. [ABSTRACT FROM AUTHOR]

Participation in European surveillance for bloodstream infection (BSI) commenced in Ireland in 1999 with all laboratories (n = 39) participating by 2014. Observational hand hygiene auditing (OHHA) was implemented in 2011. The aim of this study was to evaluate the impact of OHHA on hand hygiene compliance, alcohol hand rub (AHR) procurement and the incidence of sensitive and resistant Staphylococcus aureus and Enterococcus faecium and faecalis BSI. A prospective segmented regression analysis was performed to determine the temporal association between OHHA and outcomes. Observed hand hygiene improved from 74.7% (73.7-75.6) in 2011 to 90.8% (90.1-91.3) in 2016. AHR procurement increased from 20.1 l/ 1000 bed days used (BDU) in 2009 to 33.2 l/1000 BDU in 2016. A pre-intervention reduction of 2% per quarter in the ratio of methicillin sensitive Staphylococcus aureus BSI/BDU stabilized in the time period after the intervention (P < 0.01). The ratio of Methicillin resistant Staphylococcus aureus (MRSA) BSI/BDU was decreasing by 5% per quarter pre-intervention, this slowed to 2% per quarter post intervention, (P < 0.01). There was no significant change in the ratio of vancomycin sensitive (P = 0.49) or vancomycin resistant (P = 0.90) Enterococcus sp. BSI/BDU post intervention. This study shows national OHHA increased observed hand hygiene compliance and AHR procurement, however there was no associated reduction in BSI. [ABSTRACT FROM AUTHOR]
