Introduction Comprehensive treatment of Herpes-simplex-virus-encephalitis (HSVE) remains a major clinical challenge. The current therapy gold standard is aciclovir, a drug that inhibits viral replication. Despite antiviral treatment, mortality remains around 20% and a majority of survivors suffer from severe disability. Experimental research and recent retrospective clinical observations suggest a favourable therapy response to adjuvant dexamethasone. Currently there is no randomized clinical trial evidence, however, to support the routine use of adjuvant corticosteroid treatment in HSVE. Methods The German trial of Aciclovir and Corticosteroids in Herpes-simplex-virus-Encephalitis (GACHE) studied the effect of adjuvant dexamethasone versus placebo on top of standard aciclovir treatment in adult patients aged 18 up to 85 years with proven HSVE in German academic centers of Neurology in a randomized and double blind fashion. The trial was open from November 2007 to December 2012. The initially planned sample size was 372 patients with the option to increase to up to 450 patients after the second interim analysis. The primary endpoint was a binary functional outcome after 6 months assessed using the modified Rankin scale (mRS 0–2 vs. 3–6). Secondary endpoints included mortality after 6 and 12 months, functional outcome after 6 months measured with the Glasgow outcome scale (GOS), functional outcome after 12 months measured with mRS and GOS, quality of life as measured with the EuroQol 5D instrument after 6 and 12 months, neuropsychological testing after 6 months, cranial magnetic resonance imaging findings after 6 months, seizures up to day of discharge or at the latest at day 30, and after 6 and 12 months. Results The trial was stopped prematurely for slow recruitment after 41 patients had been randomized, 21 of them treated with dexamethasone and 20 with placebo. No difference was observed in the primary endpoint. In the full analysis set (n = 19 in each group), 12 patients in each treatment arm achieved a mRS of 0–2. Similarly, we did not observe significant differences in the secondary endpoints (GOS, mRS, quality of life, neuropsychological testing). Conclusion GACHE being prematurely terminated demonstrated challenges encountered performing randomized, placebo-controlled trials in rare life threatening neurological diseases. Based upon our trial results the use of adjuvant steroids in addition to antiviral treatment remains experimental and is at the decision of the individual treating physician. Unfortunately, the small number of study participants does not allow firm conclusions. Trial registration EudraCT-Nr. 2005–003201-81.
Emerging and re-emerging viruses may cause meningitis, encephalitis, meningoencephalomyelitis, encephalitis, Guillian-Barré-like-syndromes as well as strokes. Most important viruses belong to the family of Adenoviridae, Arbovirus, Arenaviridae, Herpesviridae, Picornaviridae, Paramyxoviridae as well as Togaviridae. Clinical presentation usually consists of a biphasic presentation. Non-specific febrile illnesses may be accompanied by rash, headache, arthralgia and myalgia. Thereafter focal neurological signs may evolve. Diagnostic strategies for the detection of emerging and re-emerging viruses may be difficult due to the short viraemic period. Pitfalls in serology may be due to antibody crossreactivity. Arboviruses are transmitted by arthropods. Aedes mosquitos are one of the vectors for arboviruses like Chikungunya-virus, Dengue-virus, Japanese-Encephalitis-B-virus and West-Nile-virus. Since the last centuries Aedes mosquitos have spread from their naturally habitat in Africa to America as well as Europe. The arboviruses risk profile depend essentially on the occurrence, the activity of the respective vector, this may be the key to fight the disease and its spread. Due to global shifts in the ecological balance but also as a result of more or less successful control measures, some diseases have become rarer, others are more common. The viruses persist in the respective vector months to years; in ticks they may persist for years and in mosquitoes 1 to 4 months. In order to survive bad climatic conditions unscathed, the viruses partially overwinter in arthropods.

Southeast Asia harbors a young population of more than 600 million people. Socioeconomic transition within the last decades, driven by globalization and rapid economic growth, has led to significant changes in lifestyle and nutrition in many countries of this region. Hence, an increase in the number of non-communicable diseases is seen in most populations of Southeast Asia. Brunei Darussalam is the smallest country in this region, with a population of around 400,000 inhabitants. Vast hydrocarbon resources have transformed Brunei into a wealthy industrialized country within the last few decades. We compared the age distribution and prevalence of cardiovascular risk factors in ischemic stroke patients between the only stroke unit in Brunei Darussalam and a tertiary stroke center from Frankfurt/Germany. Between 2011 and 2016, a total number of 3877 ischemic stroke patients were treated in both institutions. Even after adjusting for age due to different population demographics, stroke patients in Brunei were younger compared to their German counterparts. The prevalence of hypertension and diabetes mellitus was significantly higher in young age groups in Brunei, whereas no difference was observed for older patients. The rapid socioeconomic transition might be a significant risk factor for the development of non-communicable diseases, including stroke.
Due to the world-wide aging population, there is a need for specialist neurological knowledge, treatment and care. Stroke treatment is effective in reducing mortality and disability, but it is still not available in many areas of the world. We describe the set-up process of a specialized Neuroscience, Stroke and Rehabilitation Centre in Brunei Darussalam (BNSRC) in cooperation with a German hospital. This study details the setup of a stroke-, neurological intensive care- and neurorehabilitation unit, laboratories and a telemedical network to perform all evidence-based stroke treatments. All neurological on-site services and the telemedical network were successfully established within a short time. After setup, 1386 inpatients and 1803 outpatients with stroke and stroke mimics were treated. All evidence-based stroke treatments including thrombolysis and hemicraniectomy could be performed. It is possible to establish evidence-based modern stroke treatment within a short time period by a transcontinental on-site and telemedical cooperation.

Background The current Libyan civil war has originated many casualties, imposing medical challenges. War injuries are complex, requiring specialized knowledge and interdisciplinary assessment for adequate patient and intercultural management. Methods This retrospective study analyzed records of 78 Libyan patients admitted from July 2016 to November 2017 to neurological and trauma surgical departments of Krankenhaus Nordwest, Frankfurt, Germany. Issues of system preparation of the hospital, demographics, injury patterns and therapies were analyzed. The chi-squared test was used to analyze differences in injury patterns in explosion and gunshot injuries. Results Seventy-seven of seventy-eight patients were male (mean age 30.6 years). The patients received primary and secondary treatment in Tunisia (n = 39), Libya (n = 36) and Turkey (n = 23). Forty-eight patients had gunshot injuries, 37 explosion injuries, 11 both. Preparation for management of injuries included hygienic and isolation protocols, organization of interpreters and intercultural training. Patients presented with a broad variety of neurological, psychiatric and trauma surgical injuries. Fifty-six patients had sensory, 47 motor deficits. Nine reported headache, 5 vertigo, 13 visual impairment, 28 psychiatric symptoms. Eighteen patients had central nervous damage, 50 peripheral nervous damage. Central nervous damage was significantly more common in gunshot than explosion injuries (p = 0.015). Peripheral nervous damage was more common in explosion than gunshot injuries (p < 0.1). Fifty-one patients had polytrauma and 49 suffered from fractures. Therapy included surgical interventions (n = 56) and physiotherapy. Structured rehabilitation programs were often indicated. Conclusion Specialized knowledge about war injuries and their management including hospital preparation and planning regarding infrastructure may be required anytime. Injuries include a broad variety of neurological, psychiatric and trauma surgical injuries. Therefore, an interdisciplinary approach is crucial.
