Intravenous lacosamide for treatment of absence status epilepticus in genetic generalized epilepsy: A case report and review of literature.

BACKGROUND: Nearly 10 years after its introduction into the market, the significance of lacosamide in genetic generalized epilepsies is still unclear. Its new mode of action may qualify lacosamide as a therapeutic agent in this entity, but only a limited number of cases have been published so far. AIM: To describe the efficacy of lacosamide as treatment in a patient with the absence status epilepticus. METHOD: We report on a 28-year-old woman with genetic generalized epilepsy who suffered recurrent absence status epilepticus during video-EEG-monitoring. After treatment failure of first- and second-line medication, lacosamide was administered. The outcome in this patient was evaluated, and a systematic literature review was performed for the use of lacosamide in the absence status epilepticus. RESULTS: After application of 400 mg lacosamide intravenously, the absence status epilepticus terminated within 30 minutes. No further seizures or epileptiform discharges reoccurred until the end of video-EEG-Monitoring 3 days later. CONCLUSIONS: The role of lacosamide as a therapeutic option in patients with the absence status epilepticus is unclear. Only two cases have been reported so far with conflicting results. Further randomized controlled studies are required to validate the relevance of lacosamide as treatment for status epilepticus in genetic generalized and the absence epilepsy.

Do time of birth, unit volume, and staff seniority affect neonatal outcome in deliveries at ≥34+0 weeks of gestation?

OBJECTIVE: We investigated whether time of birth, unit volume, and staff seniority affect neonatal outcome in neonates born at ≥34+0 weeks of gestation. DESIGN: Population-based prospective cohort study. SETTING: Ten public hospitals in the Austrian province of Styria. SAMPLE: A total of 87 065 neonates delivered in the period 2004-2015. METHODS: Based on short-term outcome data, generalised linear mixed models were used to calculate the risk for adverse and severely adverse neonatal outcomes according to time of birth, unit volume, and staff seniority. MAIN OUTCOME MEASURES: Neonatal composite adverse and severely adverse outcome measures. RESULTS: The odds ratio for severely adverse events during the night-time (22:01-07:29 hours) compared with the daytime (07:30-15:00 hours) was 1.35 (95% confidence interval, 95% CI 1.13-1.61). There were no significant differences in neonatal outcome comparing weekdays and weekends, and comparing office hours and shifts. Units with 500-1000 deliveries per year had the lowest risk for adverse events. Adverse and severely adverse neonatal outcomes were least common for midwife-guided deliveries, and became more frequent with the level of experience of the doctors attending the delivery. With increasing pregnancy risks, senior staff attending delivery and delivering in a tertiary centre reduce the odds ratio for adverse events. CONCLUSIONS: Different times of delivery were associated with increased adverse neonatal outcomes. The management of uncomplicated deliveries by less experienced staff showed no negative impact on perinatal outcome. In contrast, riskier pregnancies delivered by senior staff in a tertiary centre favour a better outcome. Achieving a better balance in the total number of labour ward staff during the day and the night appears to be a greater priority than increasing the continuous presence of senior obstetrical staff on the labour ward during the out-of-hours period. TWEETABLE ABSTRACT: Deliveries during night time lead to a greater number of neonates experiencing severely adverse events.

Labour and Childbirth After Previous Caesarean Section: Recommendations of the Austrian Society of Obstetrics and Gynaecology (OEGGG).

The new expert recommendation from the Austrian Society of Obstetrics and Gynaecology (OEGGG) comprises an interpretation and summary of guidelines from the leading specialist organisations worldwide (RCOG, ACOG, SOGC, CNGOF, WHO, NIH, NICE, UpToDate). In essence it outlines alternatives to the direct pathway to elective repeat caesarean section (ERCS). In so doing it aligns with international trends, according to which a differentiated, individualised clinical approach is recommended that considers benefits and risks to both mother and child, provides detailed counselling and takes the patient's wishes into account. In view of good success rates (60-85 %) for vaginal birth after caesarean section (VBAC) the consideration of predictive factors during antenatal birth planning has become increasingly important. This publication provides a compact management recommendation for the majority of standard clinical situations. However it cannot and does not claim to cover all possible scenarios. The consideration of all relevant factors in each individual case, and thus the ultimate decision on mode of delivery, remains the discretion and responsibility of the treating obstetrician.

Does knowledge of fetal outcome influence the interpretation of intrapartum cardiotocography and subsequent clinical management? A multicentre European study.

OBJECTIVE: To investigate whether knowledge of fetal outcome influences retrospective interpretation of cardiotocographic tracings and subsequent management recommendations. DESIGN: Prospective online study. SETTING: Seven university hospitals in five European countries. POPULATION: Forty-two intrapartum tracings from women with singleton pregnancies and uneventful antepartum courses. METHODS: Using an online questionnaire, 123 healthcare professionals interpreted 42 tracings without any knowledge of fetal outcome and provided management recommendations according to the National Institute of Clinical Excellence guidelines (intrapartum care). Two months later, 93 of the 123 participants re-interpreted the same re-ordered tracings, this time with information on the newborn's umbilical artery pH. OUTCOME MEASURES: Comparison of the evaluation of tracing features, overall tracing classification, and management recommendations between the initial analysis and re-interpretation. RESULTS: In newborns with umbilical artery pH ≤ 7.05, knowledge of the pH value led to significant changes in the evaluation of all basic tracing features. In this group, classification of tracings as 'normal' decreased 76% (8.8-2.1%, P < 0.001), whereas classification as 'pathologic' increased 51% (44.7-67.5%, P < 0.001). In newborns with pH 7.06-7.19, classification of tracings as 'normal' decreased 36% (22.4-14.4%, P < 0.001), and in those with pH ≥ 7.20, classification of tracings as 'pathologic' decreased 40% (23.4-14.1%, P < 0.001). In the group of newborns with umbilical artery pH ≤ 7.05, the recommendations 'no attention needed' decreased 75% (10.2-2.6%, P < 0.001), and the number of recommendations 'rapid reversal of hypoxic cause or immediate delivery' increased 70.3% (42.1-71.7%, P < 0.001). CONCLUSIONS: When provided with information on adverse fetal outcome, healthcare professionals provide a more pessimistic evaluation of basic tracing features, overall classification, and clinical management recommendations. TWEETABLE ABSTRACT: Knowledge of adverse fetal outcome leads to more pessimistic CTG evaluation and management recommendations.

The Decreasing Length of Hospital Stay following Vaginal Hysterectomy: 2011-2012 vs. 1996-1997 vs. 1995-1996.

Background/Definition of the Problem: In recent years, postoperative management has changed towards rapid mobilisation, early oral feeding and rapid rehabilitation (known as Fast-Track or Enhanced Recovery Concepts). This study analysed the postoperative length of stay after vaginal hysterectomy in 3 different periods of time. Material and Methods: In the period October 2011 - September 2012, 75 patients underwent vaginal hysterectomies (± adnexectomy); another 114 vaginal or laparoscopic hysterectomies with additional operations (e.g. prolapse surgery and incontinence surgery) and malignancies were not included. The time periods August 1995 - July 1996 (n = 50) and October 1996 - September 1997 (n = 96) served as a comparison. Reducing the length of stay was not an explicit goal. Results: The median postoperative stay was shortened from 7 (5-9) to 5 (3-15) or 3 (0-5) days (p < 0.001). The recovery rate remained unchanged at 2.7 % (n = 2), cf. 2 % (n = 1) and 3.1 % (n = 3). In 40/75 cases (53.3 %), the surgery took place on the day of admission. Conclusion: The length of hospital stay after vaginal hysterectomy has more than halved since 1995/1996 and continues to decline. This development occurred without a shortened stay being an explicit goal of the clinic. The shortened length of stay does not appear to have a negative impact on postoperative complications and recovery rate.

Minocycline as potent anticonvulsant in a patient with astrocytoma and drug resistant epilepsy.

Minocycline, a tetracycline family antibiotic, is known to inhibit microglial activation and proinflammatory cytokine release in animal models. Experimental data show that these immune processes may play a role in epilepto- and ictogenesis. We present the case of a patient with marked reduction in seizure frequency during minocycline therapy with severe symptomatic epilepsy due to an astrocytoma.

[Foetal scalp blood sampling: impact on the incidence of Caesarean section and assisted vaginal deliveries for non-reassuring foetal heart rate and its use according to gestational age]. / Reduktion der operativen Entbindungsrate durch den Einsatz von Mikroblutuntersuchungen bei auffälligem CTG unter Berücksichtigung des Gestationsalters.

BACKGROUND: Interpretation of a suspicious, non-reassuring or pathological foetal heart rate tracing does not provide any direct information about foetal oxygen saturation, blood gas status or the extent of changes in pH. Without foetal scalp blood sampling, such tracings often necessitate rapid intervention to deliver the baby by Caesarean section or assisted vaginal delivery. The aim of this study was to show the impact of foetal blood sampling on reducing the number of Caesarean sections and assisted vaginal deliveries in a clinical setting in such cases. MATERIALS AND METHODS: A retrospective study of the mode of delivery in 669 women where foetal scalp blood sampling had been performed for suspicious or pathological foetal heart rate monitoring, in the period 2008-2009 was undertaken. The gestational age of the foetus was also investigated. RESULTS: Because one or more results of foetal scalp pH were within the normal range an operative delivery could be avoided in 6.4% of the study population, in spite of the non-reassuring foetal heart rate monitoring. Foetal blood sampling was performed more frequently in post-term pregnancies. CONCLUSIONS: Foetal blood analysis still is an effective tool to reduce unnecessary operative deliveries and should be regularly included in intrapartum monitoring. The risk of foetal complications is low compared with the reduction in the rate of Caesarean sections and assisted vaginal deliveries. Obstetricians are evidently becoming more willing to carry out foetal scalp blood sampling with rising gestational age.

[Primary brain tumors and brain metastases. Symptomatic epilepsy and driving ability - systematic review and expert opinion]. / Primäre Hirntumoren und Hirnmetastasen. Symptomatische Epilepsie und Fahreignung - Expertenumfrage und systematisches Review.

PURPOSE: Primary brain tumors and metastases are common causes of symptomatic epilepsy. Seizures, neurological and neuropsychological deficits can interfere with driving ability. The present paper aims to systematically review the incidence of epileptic seizures in brain tumor patients and to discuss driving ability in the context of the current German guidelines and expert opinions. METHODS: To evaluate the incidence of epileptic seizures which occur at the beginning and in the course of the disease, we performed a systematic literature research in PubMed from 1960 to 2007. Additionally on the basis of this data we performed a survey collecting expert opinions regarding the driving ability of brain tumor patients from members of the German working groups "Arbeitsgemeinschaft für prächirurgische Epilepsiediagnostik und operative Epilepsietherapie" (Working Group for Presurgical Epilepsy Diagnostics and Operative Epileptic Therapy) and "Neuroonkologische Arbeitsgemeinschaft" (Neuro-oncological Working Group). RESULTS: The incidence of epileptic seizures depends on the entity, dignity and localization of the tumor. The driving ability of brain tumor patients is not explicitly regulated in Germany. Of the interviewed experts 72% judged the guidelines to be precise enough and 44% did not want to deprive the patients of their driving ability without a first seizure, independent of the individual risk. DISCUSSION: The available studies are methodologically insufficient and show that a further evaluation is necessary to assess the driving ability. Possible restrictions of the driving ability in patients with a high risk of seizures in the course of the disease have to take into account the balance between individual rights and the interests of the general public.

High performance single crystal silicon liquid crystal light valve with good image uniformity.

This paper is composed of two distinct portions. In the first part, we introduce modified versions of the Hughes silicon liquid crystal light valve with wavefront distortions of better than lambda/4, a resolution of 16 line pairs/mm at 50% modulation concurrent with a contrast ratio of 20:1. In the second portion, we present the results and analysis of a thorough study of the dependence of the performance of this device on its various operating parameters. The contrast ratio of this device was found to be very sensitive to the accumulation phase voltage and pulse width of the driving waveform, while the resolution is strongly dependent on the depletion phase pulse width.
