Clinical Reasoning: A dizzy architect.
There is an increasing body of evidence describing an association between anti Kelch-like protein 11 (KLHL11) encephalitis and various tumors such as seminoma. However, when the diagnosis of neoplasia is uncertain and the clinical syndrome resembles those caused by other etiologies, the possibility of anti-KLHL11 encephalitis may not be obvious during early clinical evaluations. We present the case of a 68-year-old man with clinical features of anti-KLHL11 encephalitis, in whom no clear signs of an active neoplasia could be found. However, a burnt-out germ-cell tumor was suspected. This case highlights the importance of having a high clinical suspicion for anti-KLHL11 encephalitis in patients who exhibit symptoms and signs, even in absence of an active tumor
White matter lesions and intra-arterial thrombolysis
The aim of the study was to assess the influence of white matter lesions in patients with acute ischemic stroke treated with intra-arterial thrombolysis (IAT). From September 2003 to January 2010, we treated 400 patients with IAT at our institution. Of these patients, 292 were evaluated with MRI scans and included in this observational study. Clinical data were collected prospectively. Outcome after 3months was measured with the modified Rankin Scale (mRS); mRS 0-1 was considered as favorable outcome. White matter lesions were scored visually by two observers using the semiquantitative Scheltens and Fazekas scores. Logistic regression analysis was used to identify the association of white matter lesions and clinical outcome, recanalization, and cerebral hemorrhage. The severity of white matter lesions was inversely correlated with favorable outcome, survival and successful recanalization. White matter lesions were an independent predictor of outcome (OR 0.569, p=0.007) and survival (OR 0.550, p=0.018) and a weak but independent predictor for recanalization (OR 0.949, p=0.038). Asymptomatic intracerebral bleeding after IAT was associated with white matter lesions in the basal ganglia in the univariate analysis (p=0.036), but not after multivariable analysis. The severity of white matter lesions independently predicts clinical outcome and survival in patients treated with IAT. White matter lesions are also a weak but independent predictor for recanalization. Symptomatic intracranial bleeding after IAT are not associated with white matter lesions. Therefore, white matter lesions should not be considered as a contraindication against IA
First case of meningoencephalitis and bacteraemia with Flavobacterium lindanitolerans
Purpose: Flavobacterium lindanitolerans is an environmental Gram-negative, non-spore-forming rod which is usually not considered to be a human pathogen. Isolation from human clinical samples has been described only once. We report the first case of meningoencephalitis and bacteraemia with Flavobacterium lindanitolerans.
Case description: A 76-year-old female presented with fever, headache, alteration of mental status, marked meningism and dysarthria. A lumbar puncture demonstrated cerebrospinal fluid findings consistent with bacterial meningitis, and a broad-spectrum antibiotic therapy was initiated. Blood and cerebrospinal fluid cultures revealed a growth of Flavobacterium lindanitolerans. Based on antimicrobial susceptibilities testing, antibiotic treatment was changed to levofloxacin, resulting in a remission of the clinical symptoms after 21 days of treatment.
Conclusion: Flavobacterium species are extremely rare human pathogens. However, some of them have been reported to cause opportunistic infections. We describe the first case of meningoencephalitis and bacteraemia caused by Flavobacterium lindanitolerans which was effectively treated with levofloxacin for 21 days
Risk factors, aetiology and outcome of ischaemic stroke in young adults: the Swiss Young Stroke Study (SYSS).
Ischaemic stroke (IS) in young adults has been increasingly recognized as a serious health condition. Stroke aetiology is different in young adults than in the older population. This study aimed to investigate aetiology and risk factors, and to search for predictors of outcome and recurrence in young IS patients. We conducted a prospective multicentre study of consecutive IS patients aged 16-55 years. Baseline demographic data, risk factors, stroke aetiology including systematic genetic screening for Fabry disease and severity were assessed and related to functional neurological outcome (modified Rankin Scale, mRS), case fatality, employment status, place of residence, and recurrent cerebrovascular events at 3 months. In 624 IS patients (60 % men), median age was 46 (IQR 39-51) years and median NIHSS on admission 3 (IQR 1-8). Modifiable vascular risk factors were found in 73 %. Stroke aetiology was mostly cardioembolism (32 %) and of other defined origin (24 %), including cervicocerebral artery dissection (17 %). Fabry disease was diagnosed in 2 patients (0.3 %). Aetiology remained unknown in 20 %. Outcome at 3 months was favourable (mRS 0-1) in 61 % and fatal in 2.9 %. Stroke severity (p < 0.001) and diabetes mellitus (p = 0.023) predicted unfavourable outcome. Stroke recurrence rate at 3 months was 2.7 %. Previous stroke or TIA predicted recurrent cerebrovascular events (p = 0.012). In conclusion, most young adults with IS had modifiable vascular risk factors, emphasizing the importance of prevention strategies. Outcome was unfavourable in more than a third of patients and was associated with initial stroke severity and diabetes mellitus. Previous cerebrovascular events predicted recurrent ones
An exploration of lifestyle beliefs and lifestyle behaviour following stroke: findings from a focus group study of patients and family members
<p>Abstract</p> <p>Background</p> <p>Stroke is a major cause of disability and family disruption and carries a high risk of recurrence. Lifestyle factors that increase the risk of recurrence include smoking, unhealthy diet, excessive alcohol consumption and physical inactivity. Guidelines recommend that secondary prevention interventions, which include the active provision of lifestyle information, should be initiated in hospital, and continued by community-based healthcare professionals (HCPs) following discharge. However, stroke patients report receiving little/no lifestyle information.</p> <p>There is a limited evidence-base to guide the development and delivery of effective secondary prevention lifestyle interventions in the stroke field. This study, which was underpinned by the Theory of Planned Behaviour, sought to explore the beliefs and perceptions of patients and family members regarding the provision of lifestyle information following stroke. We also explored the influence of beliefs and attitudes on behaviour. We believe that an understanding of these issues is required to inform the content and delivery of effective secondary prevention lifestyle interventions.</p> <p>Methods</p> <p>We used purposive sampling to recruit participants through voluntary sector organizations (29 patients, including 7 with aphasia; 20 family members). Using focus group methods, data were collected in four regions of Scotland (8 group discussions) and were analysed thematically.</p> <p>Results</p> <p>Although many participants initially reported receiving no lifestyle information, further exploration revealed that most had received written information. However, it was often provided when people were not receptive, there was no verbal reinforcement, and family members were rarely involved, even when the patient had aphasia. Participants believed that information and advice regarding healthy lifestyle behaviour was often confusing and contradictory and that this influenced their behavioural intentions. Family members and peers exerted both positive and negative influences on behavioural patterns. The influence of HCPs was rarely mentioned. Participants' sense of control over lifestyle issues was influenced by the effects of stroke (e.g. depression, reduced mobility) and access to appropriate resources.</p> <p>Conclusions</p> <p>For secondary prevention interventions to be effective, HCPs must understand psychological processes and influences, and use appropriate behaviour change theories to inform their content and delivery. Primary care professionals have a key role to play in the delivery of lifestyle interventions.</p
Predictors of Unexpected Early Reocclusion After Successful Mechanical Thrombectomy in Acute Ischemic Stroke Patients
Vorgehen bei Patienten mit Kopfschmerzen auf der Notfallstation
HauptgrĂŒnde fĂŒr die Vorstellung auf der Notfallstation sind bei den Patienten einerseits die Sorge ĂŒber eine schwerwiegende zugrunde liegende Ursache, wie beispielsweise eine Hirnblutung, eine Meningitis oder einen Hirntumor, andererseits eine Attacke einer meist primĂ€ren therapierefraktĂ€ren Kopfschmerzerkrankung. Die Aufgabe des Neurologen oder des Notfallmediziners ist zunĂ€chst die ursĂ€chliche Einordnung unter Einsatz einer hinreichenden und gleichzeitig ressourcenorientierten paraklinischen Diagnostik. AbhĂ€ngig von der Diagnose, erfolgt dann eine ursĂ€chliche und/oder symptomatische Therapie sowie die Planung der mittelfristigen Patientenbetreuung. Im Zentrum der Diagnostik auf der Notfallstation steht die Generierung einer oder mehrerer Arbeitshypothesen, basierend auf einer ausfĂŒhrlichen Anamnese und einer klinischen Untersuchung. Red Flags sind fĂŒr schwerwiegende Begleiterkrankungen, die Kopfschmerzen verursachen könnten, von zentraler Bedeutung und helfen bei der Triage, ob eine weitere Diagnostik notwendig ist (Kasten 1) (3). Der folgende Algorithmus zeigt auf, wie bei einem Notfallpatienten mit Kopfschmerz praktisch vorgegangen werden kann
The New Swiss Postgraduate Training (Residency Program) in Neurology: Making Swiss Neurologists More Competitive
Following the creation of the first university chair for neurology (Zurich 1894), the Swiss Neurological Society (SNG) was founded in 1908.. In 1932, neurology was recognized in Switzerland as an independent specialty and included in the medical (undergraduate) curriculum. The postgraduate training (residency program) in neurology lasted first 4 years (including 1 year of internal medicine, 0.5 years of psychiatry and 2.5 years of clinical neurology as mandatory rotations). In 1985, it grew to 5 years, and in 1996 to 6 years (including 1 year of internal medicine, 3 years of clinical neurology, and 1 year of clinical neurophysiology). Considering the results of a survey among young neurologists and âlandscape changesâ such as the increasing subspecialization, economic pressure, requirements for research, number of foreign doctors, and restrictions of working hours, the SNG undertook a revision which was approved in 2016. Today, the Swiss neurology postgraduate training includes 1 year of internal medicine, a âcommon trunkâ of 3 years of general neurology (with 1 year of clinical neurophysiology including sleep), and 2 years of âfellowshipsâ with rotations in different subspecialties and up to 12 months of research
Stroke-heart syndrome: A case report and mini literature review
Despite the fact that cardiac troponin (cTn) elevation is commonly seen in the acute phase of ischemic stroke, investigating its etiology represents a challenge for healthcare practitioners. Therefore, we describe the case of an 86-year-old woman with dyspnea and cTn-elevation within the first days following acute ischemic stroke and discuss potential differential diagnoses and diagnostic dilemmas
