Eine barrierefreie Teilnahme am alltäglichen Leben stellt für Menschen mit aktiver Epilepsie häufig eine Herausforderung dar. Epileptische Anfälle können in Kindergarten, Schule und am Arbeitsplatz sowie im häuslichen Umfeld Unsicherheit und Überforderung hervorrufen. Individuell erstellte Pläne für Betreuende, Angehörige, Aufsichtspersonen und den Rettungsdienst sollen im Falle eines akuten Anfalls geeignete Handlungsanweisungen geben. Bisher gibt es hierfür im deutschsprachigen Raum keine standardisierten Vorlagen. Mit den Handlungsplänen bei epileptischen Anfällen für Laien (HEAL) bzw. Therapeuten (HEAT) werden hier 2 Formulare vorgestellt, die zum einen eine standardisierte Grundlage bieten und andererseits leicht auf den individuellen Bedarf angepasst werden können.

Tuberous sclerosis complex (TSC) is a rare genetic disease that is, besides cutaneous and visceral organ manifestations, typically associated with a severe, usually drug refractory epilepsy at a very early stage of the disease. Due to its direct effect on the mTOR signaling pathway dysregulated by TSC and its synergistic effects on other organ manifestations, the rapamycin derivative everolimus (EVE) is increasingly being used. The aim of this systematic review is to evaluate the efficacy, safety and tolerability of EVE in patients with TSC-associated, refractory epilepsy.
The hydrothermal vent tubeworm Riftia pachyptila hosts a single 16S rRNA phylotype of intracellular sulfur-oxidizing symbionts, which vary considerably in cell morphology and exhibit a remarkable degree of physiological diversity and redundancy, even in the same host. To elucidate whether multiple metabolic routes are employed in the same cells or rather in distinct symbiont subpopulations, we enriched symbionts according to cell size by density gradient centrifugation. Metaproteomic analysis, microscopy, and flow cytometry strongly suggest that Riftia symbiont cells of different sizes represent metabolically dissimilar stages of a physiological differentiation process: While small symbionts actively divide and may establish cellular symbiont-host interaction, large symbionts apparently do not divide, but still replicate DNA, leading to DNA endoreduplication. Moreover, in large symbionts, carbon fixation and biomass production seem to be metabolic priorities. We propose that this division of labor between smaller and larger symbionts benefits the productivity of the symbiosis as a whole.
Hintergrund: Die chirurgische Facharztweiterbildung erfordert neben dem Erlernen theoretischen Wissens ebenfalls den Erwerb praktisch-chirurgischer Kompetenzen. Eine Alternative zur Aus- und Weiterbildung am Patienten stellen simulationsbasierte Lehrkonzepte dar. Ziel der vorliegenden Studie ist die Analyse der Verteilung und des Einsatzes chirurgischer Simulatoren in deutschen Kliniken.
Methoden: Die Datenanalyse erfolgte auf Basis eines individuellen Onlinefragebogens mit insgesamt 19 standardisierten Fragen. Dieser wurde über die E‑Mail-Verteiler der deutschen chirurgischen Fachgesellschaften an die leitenden chirurgischen Klinikärzte versendet.
Ergebnisse: Insgesamt 267 vollständige Antwortdatensätze wurden analysiert (Rücklaufquote 12,0 %). 84,0 % der Teilnehmer gaben ihre Tätigkeit an einem Lehrkrankenhaus an. Zum Zeitpunkt der Untersuchung waren 143 chirurgische Simulatoren an 35,0 % der in die Auswertung eingeschlossenen Kliniken vorhanden. Regional zeigten sich deutliche Unterschiede zwischen den einzelnen Bundesländern. 21,1 % der Teilnehmer, an deren Klinik kein Simulator zur Verfügung steht, planten eine Neubeschaffung. Studierende (41,1 %) und Ärzte in Weiterbildung (ÄiW, 32,5 %) nutzten das Simulationstraining am häufigsten. Eine Integration in die chirurgische Weiterbildung bestand zu 81,8 % nicht. 94,0 % der beteiligten Kliniken zeigten Interesse an einer zukünftigen Integration in die chirurgische Facharztweiterbildung.
Schlussfolgerung: Die vorliegenden Ergebnisse bestätigen die besondere Bedeutung des simulationsbasierten Trainings für die chirurgische Weiterbildung an deutschen Kliniken. Gleichzeitig bestehen deutliche Informationsdefizite über das Nutzungsverhalten sowie eine defizitär empfundene Integration des Simulationstrainings in die chirurgische Weiterbildung.
The present study aims to report the currently available epidemiology of focal onset seizures in children aged >1 month to 4 years with the help of a literature review. The terms ‘seizure*’ OR ‘epilepsy’ combined with pediatric and epidemiology terms were used to search Embase, PubMed, and Web of Science up to November 16, 2021. Due to the scarcity of epidemiology data on focal onset seizures, the incidence and prevalence were estimated using the proportion of focal onset seizures in epilepsy patients from the most recently published articles. The estimated annual incidence per 100,000 children of focal onset seizures in children of 0–4 years of age ranged from 25.1 (95 % confidence interval [CI] 18.9–32.7) in the United Kingdom to 111.8 in the United States. The estimated period prevalence of focal onset seizures in children 0–4 years of age ranged from 0.15 % (99 % CI 0.13–0.18) in Canada to 0.61 % in the United States. Neurodevelopmental outcomes and psychiatric disorders were the most commonly reported comorbidities in children with epilepsy of age 0–4 years. Presence of focal onset seizures in children with different epilepsy syndromes needs to be thoroughly considered in the treatment planning of this population of interest.
Background: Multiple studies have focused on medical and pharmacological treatments and outcome predictors of patients with status epilepticus (SE). However, a sufficient understanding of recurrent episodes of SE is lacking. Therefore, we reviewed recurrent SE episodes to investigate their clinical characteristics and outcomes in patients with relapses.
Methods: In this retrospective, multicenter study, we reviewed recurrent SE patient data covering 2011 to 2017 from the university hospitals of Frankfurt and Marburg, Germany. Clinical characteristics and outcome variables were compared among the first and subsequent SE episodes using a standardized form for data collection.
Results: We identified 120 recurrent SE episodes in 80 patients (10.2% of all 1177 episodes). The mean age at the first SE episode was 62.2 years (median 66.5; SD 19.3; range 21–91), and 42 of these patients were male (52.5%). A mean of 262.4 days passed between the first and the second episode. Tonic–clonic seizure semiology and a cerebrovascular disease etiology were predominant in initial and recurrent episodes. After subsequent episodes, patients showed increased disability as indicated by the modified Rankin Scale (mRS), and 9 out of 80 patients died during the second episode (11.3%). Increases in refractory and super-refractory SE (RSE and SRSE, respectively) were noted during the second episode, and the occurrence of a non-refractory SE (NRSE) during the first SE episode did not necessarily provide a protective marker for subsequent non-refractory episodes. An increase in the use of intravenous-available anti-seizure medication (ASM) was observed in the treatment of SE patients. Patients were discharged from hospital with a mean of 2.8 ± 1.0 ASMs after the second SE episode and 2.1 ± 1.2 ASMs after the first episode. Levetiracetam was the most common ASM used before admission and on discharge for SE patients.
Conclusions: This retrospective, multicenter study used the mRS to demonstrate worsened outcomes of patients at consecutive SE episodes. ASM accumulations after subsequent SE episodes were registered over the study period. The study results underline the necessity for improved clinical follow-ups and outpatient care to reduce the health care burden from recurrent SE episodes.
Highlights
• German patients with LGS identified using most specific algorithm to date.
• Prevalence of probable LGS with epilepsy diagnosis before age 6 was 6.5 per 100,000.
• High healthcare costs of €22,787 PPY; mostly due to inpatient and home nursing care.
• Costs were greater in patients prescribed rescue medications.
• Over 10 years, LGS patients had significant mortality vs. controls (2.88 vs. 0.01%).
Abstract
Objective: This retrospective study examined patients with probable Lennox-Gastaut syndrome (LGS) identified from German healthcare data.
Methods: This 10-year study (2007–2016) assessed healthcare insurance claims information from the Vilua Healthcare research database. A selection algorithm considering diagnoses and drug prescriptions identified patients with probable LGS. To increase the sensitivity of the identification algorithm, two populations were defined: all patients with probable LGS (broadly defined) and only those with a documented epilepsy diagnosis before 6 years of age (narrowly defined). This specific criterion was used as LGS typically has a peak seizure onset between age 3 and 5 years. Primary analyses were prevalence and demographics; secondary analyses included healthcare costs, hospitalization rate and length of stay (LOS), medication use, and mortality.
Results: In the final year of the study, 545 patients with broadly defined probable LGS (mean [range] age: 31.4 [2–89] years; male: 53%) were identified. Using the narrowly defined probable LGS definition, the number of patients was reduced to 102 (mean [range] age: 7.4 [2–14] years; male: 52%). Prevalence of broadly defined and narrowly defined probable LGS was 39.2 and 6.5 per 100,000 people. During the 10-year study, 208 patients with narrowly defined probable LGS were identified and followed up for 1379 patient-years. The mean annual cost of healthcare was €22,787 per patient-year (PPY); greatest costs were attributable to inpatient care (33%), home nursing care (13%), and medication (10%). Mean annual healthcare costs were significantly greater for those with prescribed rescue medication (45% of patient-years) versus those without (€33,872 vs. €13,785 PPY, p < 0.001). Mean (standard deviation [SD]) annual hospitalization rate was 1.6 (2.0) PPY with mean (SD) annual LOS of 22.7 (46.0) days. Annual hospitalization rate was significantly greater in those who were prescribed rescue medication versus those who were not (2.2 [2.3] vs. 1.1 [1.6] PPY, p < 0.001). The mean (SD) number of different medications prescribed was 11.3 (7.3) PPY and 33.8 (17.0) over the entire observable time per patient (OET); antiepileptic drugs only accounted for 2.1 (1.1) of the medications prescribed PPY and 3.8 (2.0) OET. Over the 10-year study period, mortality in patients with narrowly defined probable LGS was significantly higher than the matched control population (six events [2.88%] vs. one event [0.01%], p < 0.001).
Conclusion: Annual healthcare costs incurred by patients with probable LGS in Germany were substantial, and mostly attributable to inpatient care, home nursing care, and medication. Patients prescribed with rescue medication incurred significantly greater costs than those who were not. Patients with narrowly defined probable LGS had a higher mortality rate versus control populations.

Abstract
Objective: Ten-year retrospective study to assess burden of illness in patients with probable Dravet syndrome (DS) identified from German healthcare data.
Methods: In the absence of an International Classification of Diseases code, patients with probable DS were identified using a selection algorithm considering diagnoses and drug prescriptions. Primary analyses were prevalence and demographics; secondary analyses included healthcare costs, annual hospitalization rate (AHR) and length of stay (LOS), medication use, and mortality.
Results: In the final study year, 64 patients with probable DS (mean [range] age: 33.2 [3–82] years; male: 48%) were identified. Prevalence: 4.7 per 100,000 people. During the study, 160 patients with probable DS were identified and followed up for 1,261 patient-years. Mean cost of healthcare was €11,048 per patient-year (PPY), mostly attributable to inpatient care (47%), medication (26%), and services and devices (19%). Annual healthcare costs were significantly greater for those with prescribed rescue medication (15% of patient-years) vs. without (€16,123 vs. €10,125 PPY, p < 0.001). Mean (standard deviation [SD]) AHR and LOS were 1.1 (1.7) and 17.5 (33.5) days PPY. AHR was significantly greater in patients with prescribed rescue medication vs. without (1.6 [2.0] vs. 1.0 [1.6] PPY, p < 0.001). Mean (SD) number of antiseizure medications prescribed was 2.6 (1.2) PPY and 5.0 (2.5) over the entire observable time for each patient. Mortality rate was significantly higher for probable DS vs. matched controls (11.88% [19 events] vs. 1.19% [172 events], p < 0.001).
Conclusion: Probable DS is associated with substantial healthcare costs in Germany.
