[German S1 Guideline Long-/Post-COVID]. / S1-Leitlinie Long-/Post-COVID.

The German Society of Pneumology initiated 2021 the AWMF S1 guideline Long COVID/Post-COVID. In a broad interdisciplinary approach, this S1 guideline was designed based on the current state of knowledge.The clinical recommendations describe current Long COVID/Post-COVID symptoms, diagnostic approaches, and therapies.In addition to the general and consensus introduction, a subject-specific approach was taken to summarize the current state of knowledge.The guideline has an explicit practical claim and will be developed and adapted by the author team based on the current increase in knowledge.

Differences in neurology residency training programmes across Europe - a survey among the Residents and Research Fellow Section of the European Academy of Neurology national representatives.

BACKGROUND AND PURPOSE: Neurology is rapidly evolving as a result of continuous diagnostic and therapeutic progress, which influences the daily work of neurologists. Therefore, updating residency training programmes is crucial for the future of neurology. Several countries are currently discussing and/or modifying the structure of their neurology residency training programme. A detailed and up-to-date overview of the available European residency training programmes will aid this process. METHODS: A questionnaire addressing numerous aspects of residency training programmes in neurology was distributed among 38 national representatives of the Resident and Research Fellow Section of the European Academy of Neurology. RESULTS: We obtained data from 32 European countries (response rate 84%). The median (range) duration of the residency training programmes was 60 (12-72) months. In the majority of countries, rotations to other medical disciplines were mandatory, mostly psychiatry (69%), internal medicine (66%) and neurosurgery (59%). However, the choice of medical fields and the duration of rotations varied substantially between countries. In 50% of countries, there were formal regulations regarding training in evidence-based medicine, teaching skills and/or leadership qualities. In many countries (75%), residents had to take an examination. CONCLUSIONS: We found substantial variation among European countries in the duration of residency training programmes, and especially in the choice of obligatory rotations to external medical disciplines. Despite a presumably similar spectrum of patients, neurology residency training programmes across Europe are not harmonized. The structure of the programme should be determined by its relevance for neurologists today and in the future.

[Delirium in idiopathic Parkinson's disease]. / Das Delir beim idiopathischen Parkinson-Syndrom.

BACKGROUND: The development of delirium in patients with idiopathic Parkinson's disease (IPD) is a feared complication, which is often associated with sustained worsening of motor symptoms and psychopathological sequelae. Little is known regarding the prevalence and incidence rates, course and prognosis. Clinical studies from which recommendations for evidence-based management of delirium in IPD can be derived are lacking. OBJECTIVE: To summarize the state of the art regarding epidemiological and clinical features of delirium in IPD. Discussion of prevention strategies and non-pharmacological and pharmacological treatment options. METHODS: A literature search was carried out in PubMed. RESULTS: The IPD is an independent risk factor for the development of delirium. Patients with IPD show poorer clinical outcome frequently with cognitive worsening and motor complications following development of delirium. CONCLUSION: So far no validated rating scales for recognition and course evaluation of delirium in IPD are available. Preventive strategies and non-pharmacological measures should be consistently implemented to improve management. There are insufficient data concerning pharmacotherapy with quetiapine and clozapine, whereas other neuroleptics are contraindicated for delirium in IPD due to antidopaminergic side effects.

[Nationwide survey of postgraduate medical training in clinical neurology]. / Deutschlandweite Evaluation der ärztlichen Weiterbildung in der klinischen Neurologie.

BACKGROUND: Currently, no data are available, which reflect the situation of medical doctors specializing in neurology in German hospitals. In order to secure the high standard of neurological patient care it is essential to evaluate the working conditions and the specialty training in neurology. OBJECTIVE: This nationwide survey was conducted throughout Germany with the aim to address problems and to give suggestions for improvements in neurological training curricula. MATERIAL AND METHODS: The survey was online from February to May 2017 and 953 neurologists undergoing further training participated. RESULTS: More than half of the young neurologists were satisfied with their medical training. One of the main problems that complicates clinical training is the workload. In addition, organizational obstacles within the clinic, such as poor structure of education or a lack of mentors, lead to dissatisfaction among participants. The size or type of the department, as well as the prevailing service system, exert only a minor influence on the quality of specialist training, although there were differences especially in the self-assessment of the participants in connection with the type of department (university hospital versus public or private hospital). CONCLUSION: Specialist training in neurology can be improved by simple arrangements, e. g., the introduction of a binding rotation scheme, internal mentoring and structured feedback. In addition, it will be necessary to relieve medical staff of administrative duties in order to create time for training and the learning of competencies.

Porosity and optical properties of zirconia films prepared by plasma ion assisted deposition.

The porosity of zirconia films prepared by plasma ion assisted deposition has been investigated by means of optical (spectrophotometric) and nonoptical analytic techniques such as transmission electron microscopy, x-ray reflection, and energy dispersive x-ray spectroscopy. A discrimination between large (open) and small (closed) pores was achieved by means of measurement of the thermal and vacuum-to-air shift. Depending on the level of plasma assistance during film preparation, the porosity was found to vary between 30 vol. % and nearly 0 vol. %. With decreasing porosity, the surface roughness determined by atomic force microscopy tends to decrease as well.

[Positionpaper on Telemonitoring in Sleep-Related Breathing Disorders]. / Positionspapier zum Telemonitoring bei schlafbezogenen Atmungsstörungen.

The use of telemonitoring in the care of patients with Sleep-related Breathing Disorders (SBD) can enhance medical support significantly. Telemonitoring aims at helping physicians to detect therapy problems early and thus improve patients' therapy adherence. Diagnostics and therapy decisions in the telemonitoring process nevertheless remain the responsibility of sleep specialists. The selection of data monitored, their evaluation and resulting consequences fall to the physician, who makes decisions and prescribes therapy in consultation with the patient. In light of professional legal and ethical requirements, it must be ensured that the extensive changes to the process flow in sleep medicine are designed in a way to guarantee high-quality patient care. In this position paper, the German Sleep Society, the German Respiratory Society, the Association of Pneumological Hospitals and the Federal Association of German Pneumologists comment on important aspects for implementation of telemonitoring for SRBD and describe the basic conditions required for its use.

Estimation of the composition of coelectron-beam-evaporated thin-mixture films by making use of the Wiener bounds.

Material mixtures offer prospective possibilities for synthesizing coating materials with tailored optical constants. We present experimental results for mixture coatings of alumina/aluminum fluoride and alumina/hafnia deposited by electron beam evaporation. Thereby, the volume filling factors of the components are commonly estimated on the basis of deposition rates measured by quartz crystal microbalance. The interplay between the vapor fluxes from the two evaporation sources, the crosstalk between quartz crystal microbalances, and the influence of the plasma source on the tooling factors limit the accuracy of this estimation, and this has motivated us to develop an alternative approach. The general idea of our approach is based on the commonly high accuracy in thin-film optical constant determination using spectrophotometry. Therefore, these optical constants serve as a reliable input for a rather simple but robust evaluation procedure based on the concept of Wiener bounds. The consistency of the obtained results is illustrated by opposing the data to the elementary film composition estimated from energy-dispersive x-ray spectroscopy.

Serum antibodies to conformational and linear epitopes of myelin oligodendrocyte glycoprotein are not elevated in the preclinical phase of multiple sclerosis.

BACKGROUND: The proposed predictive value of serum anti-myelin antibodies for the development of multiple sclerosis after a first clinically isolated syndrome was recently challenged. OBJECTIVE: To investigate myelin autoantibodies before first disease manifestation using different detection methods. METHODS: Patients with multiple sclerosis who had donated blood at a time prior to development of clinically isolated syndrome were identified via the German National Multiple Sclerosis Society. Control sera were obtained from age- and gender-matched blood donors. IgG-/IgM-antibodies against the extracellular part of native, cell surface-expressed myelin oligodendrocyte glycoprotein were detected by flow cytometry. Antibodies against linear epitopes were identified by immunoblot using recombinant myelin oligodendrocyte glycoprotein (aa1-125) and human myelin basic protein preparations. RESULTS: Fifty eight serum samples from 25 patients covering an interval of 7.3 years-2 months prior to disease onset were available. Longitudinal investigations were performed in 19 patients (2-14 samples per patient, 7 years-2 months prior to disease onset). No significant differences in the prevalence or titres of anti-myelin antibodies were detected between sera of preclinical individuals and healthy donors by either flow cytometry or immunoblot. There was no correlation between interval before clinically isolated syndrome and autoantibody status. Occurrence of antibodies was not associated with symptomatology/severity of clinically isolated syndrome. CONCLUSION: Neither anti-myelin autoantibodies against cell surface-expressed native myelin oligodendrocyte glycoprotein nor against linear epitopes have a predictive or discriminative role during the preclinical disease phase for developing clinically isolated syndrome or multiple sclerosis later in life.

Outcomes and measurement instruments used in congenital melanocytic naevi research: A systematic review.

BACKGROUND: Congenital melanocytic naevi (CMN) can have a great impact on patients' lives due to the remarkable appearance and the risk of developing melanoma and neurocutaneous melanosis. Comparison of treatment efficacy is currently hindered by the lack of standard and uniform outcome reporting; this impedes guidance on optimal management policy. To address this, we aim to perform the first step in developing a core outcome set. With this systematic review, we identified a list of domains, outcomes (including patient reported outcomes) and outcome measurement instruments used in CMN research. METHODS: The review was registered in PROSPERO, registration number CRD42018095235. A search was conducted in EMBASE (Ovid), PubMed and the Cochrane Library from 2006 to January 2019. Studies with 10 or more patients, with all sizes of CMN and reporting outcomes on interventional and conservative management were included. RESULTS: A total of 1,285 individual studies was found; 63 studies were included. We extracted 57 different outcomes and 34 outcome measurement instruments showing large heterogeneity. Patient-reported outcomes were included in 38% of studies. Few outcome measurement instruments were described. Moreover, none of the studies reported that the used instruments were ever validated in a CMN population. CONCLUSION: Heterogeneity exists in outcomes and instruments used in CMN research. The development of a core outcome set may reduce this heterogeneity in future research, thereby enabling treatment comparison and eventually facilitating guidance on management. Furthermore, this overview demonstrates a need for the use and validation of (patient reported) outcome measurement instruments for CMN.

Variation between hospitals in patient outcome after stroke is only partly explained by differences in quality of care: results from the Netherlands Stroke Survey.

BACKGROUND AND PURPOSE: Patient outcome is often used as an indicator of quality of hospital care. The aim of this study is to investigate whether there is a straightforward relationship between quality of care and outcome, and whether outcome measures could be used to assess quality of care after stroke. METHODS: In 10 centres in The Netherlands, 579 patients with acute stroke were prospectively and consecutively enrolled. Poor outcome was defined as a score on the modified Rankin scale >or=3 at 1 year. Quality of care was assessed by relating diagnostic, therapeutic and preventive procedures to indication. Multiple logistic regression models were used to compare observed proportions of patients with poor outcome with expected proportions, after adjustment for patient characteristics and quality of care parameters. RESULTS: A total of 271 (47%) patients were dead or disabled at 1 year. Poor outcome varied across the centres from 29% to 78%. Large differences between centres were also observed in clinical characteristics, prognostic factors and quality of care. For example, between hospital quartiles based on outcome, age >or=70 years varied from 50% to 65%, presence of vascular risk factors from 88% to 96%, intravenous fluids when indicated from 35% to 81%, and antihypertensive therapy when indicated from 60% to 85%. The largest part of variation in patient outcome between centres was explained by differences in patient characteristics (Akaike's Information Criterion (AIC) = 134.0). Quality of care parameters explained a small part of the variation in patient outcome (AIC = 5.5). CONCLUSIONS: Patient outcome after stroke varies largely between centres and is, for a substantial part, explained by differences in patient characteristics at time of hospital admission. Only a small part of the hospital variation in patient outcome is related to differences in quality of care. Unadjusted proportions of poor outcome after stroke are not valid as indicators of quality of care.

Dietary intake of natural sources of docosahexaenoic acid and folate in pregnant women of three European cohorts.

BACKGROUND: Folic acid plays a fundamental role in cell division and differentiation. Docosahexaenoic acid (DHA) has been associated with infantile neurological and cognitive development. Thus, optimal intrauterine development and growth requires adequate supply of these nutrients during pregnancy. METHODS: Healthy pregnant women, aged 18-41 years, were recruited in Granada (Spain; n = 62), Munich (Germany; n=97) and Pécs (Hungary; n=152). We estimated dietary DHA and folate intake in weeks 20 (w20) and 30 of gestation (w30) using a food frequency questionnaire with specific focus on the dietary sources of folate and DHA. RESULTS: Both w20 and w30 Spanish participants had significantly higher daily DHA intakes (155+/-13 and 161+/-9 mg/1,000 kcal) than the German (119+/-9 and 124 +/- 12 mg/1,000 kcal; p=0.002) and Hungarian participants (122+/-8 and 125 +/- 10 mg/1,000 kcal; p=0.005). Hungarian women had higher folate intakes in w20 and w30 (149+/-5 and 147+/-6 microg/1,000 kcal) than Spanish (112+/-2 and 110+/-2 microg/1,000 kcal; p<0.001) and German participants (126+/-4 and 120+/-6 microg/1,000 kcal; p<0.001), respectively. CONCLUSION: Dietary DHA and folate intake of pregnant women differs significantly across the three European cohorts. Only 7% of the participants reached the recommended folate intake during pregnancy, whereas nearly 90% reached the DHA recommended intake of 200 mg per day.

Cross-sectional serological study of canine Leishmania infection in Fortaleza, Ceará state, Brazil.

Visceral leishmaniasis (VL) is one of the most important reemerging parasitic disease in the world. The domestic dog is the main reservoir in urban environments. The aim of this work was to extend the knowledge on canine Leishmania infection in the city of Fortaleza in northeastern Brazil, identifying the risk factors inherent in dog susceptibility to the infection. Two populations were analyzed, domestic dogs from clinics and the Veterinary Hospital Unit of Ceará State University and stray dogs captured by the Center for Zoonosis Control in Fortaleza. Blood samples were collected and centrifuged and the sera were stored at -20 degrees C. ELISA, with soluble crude Leishmania chagasi antigens (LTCC - WDCM731) was used for diagnosis. A total of 1,381 samples were tested, 750 from domestic and 631 from stray dogs. The seroprevalence of canine VL was 21.4% (135/631) in stray dogs and 26.2% (197/750) in domestic dogs. The seroprevalence of Leishmania infection in the six administrative regions of the city (Secretarias Executivas Regionais, or SER) among stray dogs was highest in SER V, representing 31.4% of the cases, with large dogs more infected (27.7%). Among domestic dogs Leishmania infection was most prevalent in SER V (38.5%) and VI (37.6%). The dogs' age (1-6 years), large size, environment with dense vegetation and presence of clinical signs compatible with Leishmania infection were associated with the illness in domestic dogs. The frequency of the infection varied seasonally. The seroprevalence was greatest in July and December. These results confirm Fortaleza is an endemic area for canine VL and suggest some variables associated with increasing infection risk in dog populations.

[Success of carotid endarterectomy dependent on type of atherosclerotic plaque and gender, among others]. / Succes van carotisendarteriëctomie afhankelijk van onder meer het type atherosclerotische plaque en het geslacht.

Carotid endarterectomy (CEA) reduces the risk of stroke in both symptomatic and asymptomatic patients with a high-grade stenosis of the internal carotid artery. Surgery, however, is less beneficial for women than for men. Besides gender, other factors, like degree ofstenosis and plaque morphology, influence the risk of stroke and the beneficial effect of CEA. A recent study shows that women, asymptomatic women in particular, have more stable atherosclerotic carotid plaques than men. Increasing knowledge regarding local plaque characteristics should be carried through to clinical practice. Further studies, especially prospective studies, are needed to identify subgroups of patients that will benefit most from CEA. Low surgical morbidity and mortality remain a prerequisite to perform CEA in symptomatic carotid stenosis and even more so in asymptomatic carotid stenosis.

[Differences between hospitals in outcome after a stroke are only partially explained by differences in the quality of care]. / Verschillen tussen ziekenhuizen in uitkomst na een herseninfarct vooral verklaard door patiëntkenmerken en slechts ten dele door verschillen in de kwaliteit van zorg.

OBJECTIVE: To determine the extent to which the outcome of stroke patients stroke is correlated with patient characteristics and care process parameters, and to determine whether outcome measures can be used to measure the quality of hospital care provided for these patients. DESIGN: Descriptive cohort study. METHODS: At 10 hospitals in the Netherlands, in the period October 2002-April 2003, patients with acute stroke were included in the study. Poor outcome was defined as dead or disabled at 1 year (a score on the modified Rankin scale > or = 3). Quality of the care was assessed by relating diagnostic, therapeutic and preventive procedures to indication. Multiple logistic regression models were used to compare observed numbers of patients with a poor outcome with expected numbers per hospital, after adjustment for patient characteristics and quality of care parameters. RESULTS: In total, 579 patients were included in the study, of which 271 (47%) were dead or disabled at 1 year. Poor outcome varied across the hospitals from 29 to 78%. The mean age was 70 years. There were large differences between hospitals with respect to patient characteristics and quality of care. Most of the differences in outcome between hospitals were explained by the differences in patient characteristics (Akaike's information criterion (AIC) = 134). Quality of care parameters explained just a small additional part of the variation in patient outcome (AIC = 5.5). CONCLUSIONS: Large differences between Dutch hospitals in the patient outcome after stroke could mostly be explained by differences in patient characteristics. Only a small part of the hospital variation in patient outcome was related to differences in quality of care. Therefore, outcome indicators cannot be regarded as valid performance indicators for care following a stroke.

Neomycin resistance as a dominant selectable marker for selection and isolation of vaccinia virus recombinants.

The antibiotic G418 was shown to be an effective inhibitor of vaccinia virus replication when an appropriate concentration of it was added to cell monolayers 48 h before infection. Genetic engineering techniques were used in concert with DNA transfection protocols to construct vaccinia virus recombinants containing the neomycin resistance gene (neo) from transposon Tn5. These recombinants contained the neo gene linked in either the correct or incorrect orientation relative to the vaccinia virus 7.5-kilodalton gene promoter which is expressed constitutively throughout the course of infection. The vaccinia virus recombinant containing the chimeric neo gene in the proper orientation was able to grow and form plaques in the presence of G418, whereas both the wild-type and the recombinant virus with the neo gene in the opposite polarity were inhibited by more than 98%. The effect of G418 on virus growth may be mediated at least in part by selective inhibition of the synthesis of a subset of late viral proteins. These results are discussed with reference to using this system, the conferral of resistance to G418 with neo as a positive selectable marker, to facilitate constructing vaccinia virus recombinants which contain foreign genes of interest.

Sandifer syndrome--a multidisciplinary diagnostic and therapeutic challenge.

Sandifer syndrome, named after the neurologist Paul Sandifer, was first reported by M. Kinsbourne in 1962 who noticed a disorder of the upper gastrointestinal tract with neurological manifestations occurring in children and adolescents. Sandifer syndrome is a combination of gastro-oesophageal reflux disease with spastic torticollis and dystonic body movements with or without hiatal hernia. It is hypothesised that the positioning of the head provides relief from abdominal discomfort caused by acid reflux. The true pathophysiological mechanisms of the condition are still unclear. We report the diagnosis of Sandifer syndrome in a 9-year-old boy with a history of chronic torticollis and dystonic episodes for 5 years associated with abdominal symptoms. The cause of the dystonic body movements had not been found, although multiple neuropsychiatric diseases were suspected. The patient had been seen by many different specialities including Paediatrics, Paediatric Neurology, Psychology, Orthopaedic Surgery and ENT but the reason for the torticollis remained elusive. Unclear abdominal discomfort was the indication for an endoscopy that revealed severe gastro-oesophageal reflux disease with oesophagitis III degrees and a hiatal hernia which led to the correct diagnosis of Sandifer syndrome. After medical treatment and laparoscopic floppy Nissen fundoplication the symptoms nearly resolved 3 months after operation. Few reports of this syndrome exist, but Sandifer syndrome is probably underrecognised. Children with torticollis, dystonic episodes or atypical seizures should be evaluated for GERD and Sandifer syndrome. Early surgery, for example a laparoscopic floppy Nissen fundoplication or a Toupet procedure, can resolve the symptoms.

Long-term survival and vascular event risk after transient ischaemic attack or minor ischaemic stroke: a cohort study.

BACKGROUND: Determinants of survival and of risk of vascular events after transient ischaemic attack (TIA) or minor ischaemic stroke are not well defined in the long term. We aimed to restudy these risks in a prospective cohort of patients after TIA or minor ischaemic stroke (Rankin grade< or =3), after 10 years or more. METHODS: We assessed the survival status and occurrence of vascular events in 2473 participants of the Dutch TIA Trial (recruitment in 1986-89; arterial cause of cerebral ischaemia). We included 24 hospitals in the Netherlands that recruited at least 50 patients. Primary outcomes were all-cause mortality and the composite event of death from all vascular causes, non-fatal stroke, and non-fatal myocardial infarction. We assessed cumulative risks by Kaplan-Meier analysis and prognostic factors with Cox univariate and multivariate analysis. FINDINGS: Follow-up was complete in 2447 (99%) patients. After a mean follow-up of 10.1 years, 1489 (60%) patients had died and 1336 (54%) had had at least one vascular event. 10-year risk of death was 42.7% (95% CI 40.8-44.7). Age and sex-adjusted hazard ratios were 3.33 (2.97-3.73) for age over 65 years, 2.10 (1.79-2.48) for diabetes, 1.77 (1.45-2.15) for claudication, 1.94 (1.42-2.65) for previous peripheral vascular surgery, and 1.50 (1.31-1.71) for pathological Q waves on baseline electrocardiogram. 10-year risk of a vascular event was 44.1% (42.0-46.1). After falling in the first 3 years, yearly risk of a vascular event increased over time. Predictive factors for risk of vascular events were similar to those for risk of death. INTERPRETATION: Long-term secondary prevention in patients with cerebral ischaemia still has room for further improvement.

Viral acylproteins: greasing the wheels of assembly.

Viruses take advantage of the host's protein modification and targeting pathways to modify their own proteins and to ensure that they assume active configurations and locate appropriately for assembly. In many viruses, one recurrent theme in such processes is exploitation of cellular protein acylation pathways for the addition of myristic and palmitic acid to capsid or envelope proteins.

CO(2) reactivity measured by perfusion MRI during transient focal cerebral ischemia in rats.

BACKGROUND AND PURPOSE: CO(2) response was examined in rats undergoing 60 minutes of middle cerebral artery occlusion (MCAO) and 4.5 hours of reperfusion. Because it is not clear whether the vasoreactivity improves during reperfusion in parallel with tissue recovery, CO(2) response was determined spatially resolved, sequentially in the initially ischemic but later recovered areas and in the permanently damaged areas. METHODS: Apparent diffusion coefficient (ADC) maps were calculated from diffusion-weighted images, whereas CO(2) reactivity maps were determined from the difference in perfusion signal intensity before and after CO(2) stimulation. CO(2) reactivity (administration of 6% CO(2) for 5 minutes) was expressed in % change of perfusion signal intensity/mm Hg of PCO(2) increase. ATP levels of tissue were used as a measure of outcome. The recovered and permanently damaged tissues were differentiated by combined use of end-ischemic ADC map and ATP image at the end of the experiment. RESULTS: The preischemic (control) CO(2) reactivity of 3.5+/-0.9%/mm Hg decreased dramatically during MCAO in the ischemic hemisphere. During reperfusion, it remained <1%/mm Hg in the region with end-ischemic ADC <80% of the preischemic control value, but showed gradual recovery in the region with end-ischemic ADC >80% of control. Although at the end of the experiment the CO(2) reactivity was significantly higher in the recovered tissue than in the permanently damaged tissue (1.15+/-0.44 and 0.13+/-0.47%/mm Hg, respectively; P:<0.01), it still remained far below the normal control value (P:<0.01). CONCLUSIONS: The noninvasive perfusion-weighted MR imaging in combination with a CO(2) challenge permits the investigation of the spatially resolved vascular reactivity during a longitudinal study of cerebral ischemia. Our data suggest that severe ischemia is followed by a prolonged disturbance of CO(2) reactivity, despite already normalized energy metabolism.

Stereotactic treatment of intracerebral hematoma by means of a plasminogen activator: a multicenter randomized controlled trial (SICHPA).

BACKGROUND AND PURPOSE: Treatment of intracerebral hematoma (ICH) is controversial. An advantage of neurosurgical intervention over conservative treatment of ICH has not been established. Recent reports suggest a favorable effect of stereotactic blood clot removal after liquefaction by means of a plasminogen activator. The SICHPA trial was aimed at investigating the efficacy of this treatment. METHODS: A stereotactically placed catheter was used to instill urokinase to liquefy and drain the ICH in 6-hour intervals over 48 hours. From 1996 to 1999, 13 centers entered 71 patients into the study. Patients were randomized into a surgical group (n=36) and a nonsurgical group (n=35). Admission criteria were the following: age >45 years, spontaneous supratentorial ICH, Glasgow Eye Motor score ranging from 2 to 10, ICH volume >10 cm3, and treatment within 72 hours. The primary end point was death at 6 months. As secondary end points, ICH volume reduction and overall outcome measured by the modified Rankin scale were chosen. The trial was prematurely stopped as a result of slow patient accrual. RESULTS: Seventy patients were analyzed. Overall mortality at day 180 after stroke was 57%; this included 20 of 36 patients (56%) in the surgical group and 20 of 34 patients (59%) in the nonsurgical group. A significant ICH volume reduction was achieved by the intervention (10% to 20%, P<0.05). Logistic regression analysis indicated the possibility of efficacy for surgical treatment (odds ratio, 0.23; 95% confidence interval, 0.05 to 1.20; P=0.08). The odds ratio of mortality combined with modified Rankin scale score 5 at 180 days was also not statistically significant (odds ratio, 0.52; 95% confidence interval, 1.2 to 2.3; P=0.38). CONCLUSIONS: Stereotactic aspiration can be performed safely and in a relatively uniform manner; it leads to a modest reduction of 18 mL of hematoma reduction over 7 days when compared with control, which has a 7-mL reduction, and therefore may improve prognosis.
