- Abstract
Purpose: New antiepileptic drugs (AEDs) are increasingly applied in second-line therapy of status epilepticus (SE). In our study, we analyzed the impact of the choice of second-line AEDs on the course and prognosis of SE.Methods: This retrospective single- center study used data of an 8 year cohort of SE in adults from 2007 to 2014. Based on the year of market introduction with a cutoff at 1990, we classified AEDs as traditional or new. Prescription pattern associated differences in prognosis were measured through univariate and multivariable analysis of 3 endpoints: occurrence of refractory SE (RSE), functional outcome in survivors to discharge (good: mRS at discharge <3 or identical to admission mRS; otherwise poor), and in-hospital mortality.Results: From 362 SE episodes during the study period, 222 episodes were included into the study, among those 150 episodes treated with new and 72 with traditional AEDs. Use of new AEDs increased during the study period. After adjustment for confounders, treatment with new AEDs was on the one hand associated with higher rate of RSE occurrence (OR 1.95, 95 % CI 1.05-3.62, p = 0.03), but, on the other hand, also with better functional outcome at discharge (OR 2.64, 95 % CI 1.16-6.00, p = 0.02), while it was not an independent predictor of in- hospital mortality (OR 0.88, 95 % CI 0.33-2.33, p = 0.80).Conclusion: Our observation that new AEDs may be associated with a higher rate of RSE development and relatively better functional outcome when adjusted for the premorbid mRS needs confirmation in prospective studies.

- Abstract
Background: The influence of prior nicotine or alcohol use (legal drug use [LDU]) on outcome measures after intracerebral hemorrhage (ICH) is insufficiently established. We investigated drug-specific associations with (1) neuroradiologic and clinical parameters and (2) functional long-term outcome after ICH.Methods: This observational cohort study analyzed consecutive spontaneous patients with ICH (n = 554) from our prospective institutional registry over a 5-year study period (January 2010 to December 2014). We compared no-LDU patients with LDU patients, and patients using only nicotine, only alcohol, or both. To account for baseline imbalances, we reanalyzed cohorts after propensity score matching.Results: Prevalence of prior LDU was 197 of 554 (35.6%), comprising 94 of 554 (17.0%) with only nicotine use, 33 of 554 (6.0%) with only alcohol use, and 70 of 554 (12.6%) with alcohol and nicotine use. LDU patients were younger (65 [56-73] versus 75 [67-82], P <.01), less often female (n = 61 of 197 [31.0%] versus n = 188 of 357 [52.7%], P <.01), had more often prior myocardial infarction (n = 29 of 197 [14.7%] versus n = 24 of 357 [6.7%], P <.01), and in-hospital complications (sepsis or systemic inflammatory response syndrome: n = 95 of 197 [48.2%] versus n = 98 of 357 [27.5%], P <.01; pneumonia: n = 89 of 197 [45.2%] versus n = 110 of 357 [30.8%], P <.01). Except for an increased risk of pneumonia (odds ratio 2.22, confidence interval [1.04-4.75], P = .04) in patients using both nicotine and alcohol, we detected no significant differences upon reanalysis after propensity score matching of neuroradiologic or clinical parameters, complications, or long-term outcome between patients with and without LDU (mortality: n = 48 of 150 [32.0%] versus n = 45 of 150 [30.0%], P = .71; favorable outcome [modified Rankin Scale 0-3]: n = 56 of 150 [37.3%] versus n = 53 of 150 [35.3%], P = .72).Conclusions: Prior nicotine use, alcohol use, and their combination were associated with significant differences in baseline characteristics. However, adjusting for unevenly balanced baseline parameters revealed no differences in functional long-term outcome after ICH. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Purpose: The aim of this study was to assess factors associated with the use of topiramate (TPM) in refractory status epilepticus (RSE).Methods: We retrospectively reviewed RSE episodes over a 12-year period. Episodes treated with and without TPM were compared in terms of demographics, RSE characteristics, clinical course, and outcome in univariate and multivariate analyses. Subgroups defined by type of RSE were studied separately. Functional outcome was assessed with the modified Rankin Scale.Results: Among 71 episodes, 17 (23.9%) were treated with TPM and seizure control was achieved in all of these. The results of unadjusted comparisons suggested a use of TPM in younger and healthier patients who received more perseverant treatment indicated by a higher number of antiepileptic drugs applied. In multivariate analysis adjusting for RSE duration, however, these associations lost significance. Furthermore, TPM was not a predictor of successful RSE termination in neither the overall cohort, nor in the subgroup of complex-partial RSE.Conclusion: After multivariate adjustment, no significant differences were observed between episodes treated with and without TPM in baseline characteristics, treatment, and outcome. Regarding the latter, this study does therefore not yield evidence for a particular efficacy of TPM in RSE. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background and Purpose: The influence of chronic kidney disease (CKD) on functional outcome in intracerebral hemorrhage (ICH) is scarcely investigated and reported findings are conflicting mostly because of nonaccounting for imbalances. Aim of the present study was to determine the impact of CKD on functional long-term outcome in ICH-patients.Methods: In this observational cohort study of spontaneous ICH-patients admitted to our Department of Neurology between 2006 and 2015 we investigated retrospectively as primary outcome the dichotomized functional status (modified-Rankin-Scale = 0-3-versus-4-6) at 12 months according to renal function (CKD versus non-CKD), including categorial estimates of the glomerular filtration rate subanalyses. Confounding was addressed by propensity-score(ps)-matching and adjusted multivariable regression analyses.Results: We identified 1076 eligible ICH-patients, of which 131 (12.2%) suffered from CKD on hospital admission. Confounders associated with CKD consisted of hypertension (P = .023), Diabetes mellitus (P = .001), prior ischemic stroke and/or transitory ischemic attack (TIA) (P = .021), congestive heart failure (P < .01), impaired liver function (P < .01), antiplatelet therapy (P = .01), poorer premorbid functional status (P < .01), and deep ICH-location (P = .006). After balancing for confounding, patients with CKD showed a significantly decreased rate of favorable functional outcome at 12 months (CKD:29 of 111(26.1%)-versus-non-CKD:78 of 206 (37.9%); P = .035). Subanalyses showed that stages of CKD were evenly associated with mortality at 12 months (GFR category G3a, OR:2.811; CI (1.130-6.994); P = .026; GFR category G3b, OR:1.874; CI (.694-5.058); P = .215; GFR category G4, OR:10.316; CI (1.976-53.856); P = .006; GFR category G5, OR:8.989; CI (1.900-42.518); P = .006).Conclusions: As compared to ICH-patients without CKD, those with CKD show increased rates of mortality and worse functional outcomes even after statistical correction for imbalanced baseline characteritsics. This finding is presumably linked to comorbidity and warrants further investigation in prospective studies. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: Whether time of hospital admission-during or outside regular working hours-affects functional outcome in intracerebral hemorrhage (ICH) is unestablished as previous analyses have focused on mortality only. We here investigate whether on- versus off-hour hospital admission in ICH is associated with levels of invasiveness and clinical outcomes.Methods: Based on the UKER registry (NCT03183167) we grouped ICH-patients according to on- versus off-hour hospital admission. Primary outcome measures was functional outcome after 3 months using the modified Rankin scale (mRS) dichotomized into favorable (mRS = 0-3) and unfavorable (mRS = 4-6). Multivariate regression analyses were used to adjust for baseline imbalances, and subgroup analyses were performed to explore associations of on- versus off-hour admission with invasiveness of therapeutic interventions.Results: A total of 438/1269 (34.5%) of ICH-patients were admitted during regular working hours. Mortality rates were not significantly different among patients with on- versus off-hour admission. On-hour patients showed a significantly larger proportion of patients with favorable outcome (on-hour: mRS = 0-3 after 3 months: 176/416 (42.3%) versus off-hour: 265/784 (33.8%); P = .004). Analysis of invasive therapeutic interventions revealed that likelihood of favorable outcome was significantly increased among on-hour admitted patients who did not require neurosurgical interventions (no external ventricular drain n = 349, OR: 1.67[1.13-2.48], P < .05; no hematoma evacuation surgery n = 423, OR: 1.51[1.07-2.14], P < .05).Conclusion: This study verified an "off-hour effect" in ICH that relates to functional outcome, rather than mortality, and which may be linked to different levels of invasive therapeutic interventions in patients admitted during off-hour.

The article describes the case report of a 21-year-old female patient with a history of mild headaches, general fatigue, tonic-clonic seizures and nephropathic cystinosis, and who was diagnosed with posterior reversible encephalopathy syndrome (PRES). Detailed brain examinations revealed symptoms of PRES in the parieto-occipital and fronto-parietal regions and increased c-reactive protein and leukocyte count. The patient stabilized after taking steroids, carbamazepine and hemodialysis.
