Fluctuating parkinsonism: a pilot study of single afternoon dose of levodopa methyl ester

Thirty-four patients with idiopathic fluctuating Parkinson's disease and early afternoon delayed on or severely resistant off periods, in spite of long-term antiparkinsonian therapy, were studied. The first afternoon levodopa administration was substituted with an equimolar dosage of the liquid formulation levodopa methyl ester (LDME). The major end-points for efficacy were latency to on and duration of on periods. The patients were divided into five subgroups according to their baseline treatment and they were evaluated monthly for 6 months using the Unified Parkinson's Disease Rating Scale. The patients completed weekly self-evaluation using an on-off chart. LDME was well tolerated by all the patients. A statistically significant reduction in latency to on was observed in all patients. The clinical effect of LDME remained stable during the treatment period (repeat measures ANOVA). The more rapid clinical effect of LDME and its stable and predictable antiparkinsonian activity represents a new and useful approach for treating patients with complicated Parkinson's disease.     

Über die sogenannte „zentrale Tonusdifferenz“ mit Nystagmusbereitschaft nach einer Seite

Zusammenfassung An Hand von 71 sowohl otologisch als auch neurologisch-psychiatrisch untersuchten Fällen wird zur Frage der sog. zentralen Tonusdifferenz Stellung genommen.1. In 40% der Beobachtungen waren als Ursache des einseitigen Nystagmusüberwiegens Schäden im Labyrinth bzw. im Bereich des 1. vestibulären Neurons anzunehmen.2. Bei 35% der Untersuchten war sowohl eine periphere als auch zentrale Verursachung möglich. Überwiegend handelt es sich um Patienten mit einem klinischen Halswirbelsäulensyndrom. Der funktionelle Charakter der Störung wird diskutiert.3. In 25% unserer Fälle lagen sicher zentrale Schäden vor, jedoch fand sich mit 2 Ausnahmen kein Anhalt für die Annahme einer Hirnstammläsion als Ursache der Nystagmusbereitschaft nach einer Seite.Therapieversuche werden erwähnt.Der Begriff zentrale Tonusdifferenz wird als mißverständlich abgelehnt und betont, daß dem einseitigen Nystagmusüberwiegen keineswegs ein Hinweischarakter auf eine Hirnstammcontusion zukommt. Die Nystagmusbereitschaft nach einer Seite kann von jedem Abschnitt des vestibulären Systems ausgelöst werden.Teilergebnis eines Forschungsauftrages des Bundesministeriums für Arbeit.     

Effect of tryptophan metabolites on activity of the epileptogenic focus in the frog hippocampus

Summary In frogs with the epileptogenic foci made by injection of penicilline (1000 U in 0.4 mcl) in the primordial hippocampus it was shown that preliminary administration of two kynurenines quinolinic acid (0,1g) and d,l-kynurenine (1g), in the foci region, and their injection in the functioning epileptogenic foci led to a strong increase of the interictal epileptiform discharges and of the electrographic correlates of fits on the EEG. Anthranilic acid (0.1, 1.0 and S.0g) did not influence the activity of epileptogenic foci. Serotonin (1g) and 5-methoxytryptamine (1g) essentially decreased it. Provocating effect of kynurenines on neurons in epileptogenic foci is supposed to play a certain role in pathogenesis of epilepsy.     

Hyperkinetic children: Early indicators of potential school failure

Hyperkinetic children are identified as a population-at risk upon admission to kindergarten. The etiology of hyperkinetic behavior is controversial. Organic driveness, hyperkinetic behavior disorder, postencephalitic behavior, brain damage with behavioral and conceptual deficit, Strauss syndrome, have all been used to label essentially similar symptom constellations. Bypassing the area of controversy, a study is reported that demonstrates that children who were identified as hyperkinetic (using behavioral criteria developed in an earlier study) were (1) absent from school more frequently, and (2) did remarkably less well on standardized tests of school readiness than their peers rated nonhyperkinetic. The implications are discussed and suggestions made for the development of intervention programs.An earlier version of this paper was presented at the Annual Meeting of the American Orthopsychiatric Association, March, 1967.     

Vegetative Funktionen und körperliche Aktivität in der endogenen Depression

Zusammenfassung Bei einem 66 Jahre alten männlichen Patienten mit 48-h-Zyklen einer unipolaren endogenen Depression wurden vegetative Funktionen untersucht. Speichelsekretion, Körpertemperatur und körperliche Aktivität wurden am Tage in 3-h-Abständen und einmal nachts gemessen. Die Stimmung wurde mit Hilfe von zwei Selbstbeurteilungsskalen beurteilt. Die Skalenwerte ergaben eine regelmäßige Abfolge von guten und schlechten Tagen. Die Speichelsekretion war an guten Tagen gegenüber den Meß-werten an schlechten Tagen erhöht. Dieser Unterschied war am Morgen besonders deutlich (P<0.002, 10.00). Die Form des 24-h-Profils der Speichelsekretion war an guten und schlechten Tagen unterschiedlich: an guten Tagen lag das Maximum um 10.00 Uhr, an schlechten Tagen um 16.00 Uhr. Dagegen zeigte die Lage des nächtlichen Minimums keinen Unterschied zwischen guten und schlechten Tagen. Die Meßwerte der Körpertemperatur waren gegenüber Normalwerten deutlich erhöht (Mittelwerte um 37,2° C) und zeigten eine geringe Amplitude des Tagesganges. An guten Tagen lag die Körpertemperatur tagsüber im Mittel um 0,1°C höher als an schlechten Tagen. Die körperliche Aktivität (Arm und Bein) wurde mit Hilfe eines Aktometers (activity watch) registriert. Die Meßwerte waren tagsüber an guten Tagen höher als an schlechten Tagen. Die vorliegenden Befunde geben Hinweise auf eine zentrale Regulationsstörung vegetativer Funktionen bei der endogenen Depression.Die Autoren dieser Arbeit sind Mitglieder einer Arbeitsgruppe, die sich am Max-PlanckInstitut für Psychiatrie mit der Pathophysiologie und Chronobiologie depressiver Syndrome befaßt     

Prevalence of known and hidden alcoholism in the revisited lundby population

Summary Using the new data from a second followup of the Lundby 1947 cohort, the aim of the present paper has been to analyze some relationships between known and hidden alcoholism in a Swedish general population sample. Information was collected by psychiatrists trough free, exploratory field interviews checked against documentary records. Alcoholism was medically defined for present purposes. Information was obtained for 98% of the 952 men surviving the cross-section date July 1, 1972. The distribution of alcoholism and other psychiatric disorders in the total population and in age subgroups was analyzed epidemiologically. The true prevalence of alcoholism in the adult men was 9.5%, comprising 7.2% known and 2.3% hidden. The proportion of hidden to known cases was 0.301 (Temperance Boards 0.871, Psychiatric Agencies 0.961, Drinking and driving offences 4.31). The main finding that about 70% of male alcoholics in Lundby appears to be known to the agencies is at variance with current views that there is an iceberg under the tip, though consistent with Rubington's suggestion that so-called hidden alcoholism is not totally but partially invisible in welfare societies.     

Obsessive-Compulsive Disorder in Popular Magazines

To examine what the general public is learning about Obsessive-Compulsive Disorder (OCD) through popular magazines, all articles listed in the Reader's Guide to Periodical Literature under the topic headings of obsessive-compulsive behavior or obsessive-compulsive disorder between 1983 and 1997 were read and rated. Only 31 of the 107 articles under these headings dealt explicitly with OCD, and these were found to be reasonably accurate in their presentations of symptoms, causes, and treatments. Many of the other articles under the target headings, however, focused on incidents of stalking of famous people by obsessed fans. The implications of the content patterns of these articles for understanding and misunderstanding of OCD are discussed.     

Cytoplasmic and axoplasmic density variations in relation to hyperactivity

Summary The density of the cytoplasm and axoplasm of the anterior horn cell in rats was determined by X-ray microradiography. The average density of the cytoplasm of more than 400 cells from control rats was 0.31 g/³, while that of over 600 cells from rats fed IDPN (- iminodipropionitrile) was 0.43 g/³.Hyperactivity developed during the first 5 weeks and was associated with a gradual increase in cytoplasmic density to 0.51 g/³.At 6 weeks there was a drop in density to 0.36 g/³ which coincided with the appearance of axonal balloons having a density of 0.17 g/³.During the 7–12th week on the diet, the cytoplasmic density showed a gradual increase to 0.59 g/³ and the balloons to 0.29 g/³.The volume of the nerve cells remained fairly constant. The density increases were discussed in relation to hypertrophy, dystrophy, and hyperactivity.

Zusammenfassung Die Dichte des Cytoplasmas und Axoplasmas der Vorderhornzellen von Ratten wurde durch Röntgenmikroradiographie bestimmt. Die mittlere Dichte des Cytoplasmas von mehr als 400 Zellen der Kontrollratten war 0,31 g/³, während die mittlere Dichte von mehr als 600 Zellen der Ratten, die mit IDPN (- iminodipropionitrile) gefüttert waren, 0,43 g/³ war.Hyperaktivität entwickelte sich während der ersten 5 Wochen und war mit einer progressiven Zunahme der Cytoplasmadichte bis auf 0,51 g/³ verbunden.Nach 6 Wochen sank die Dichte auf 0,36 g/³. Diese Tatsache traf mit dem Auftreten der Axonauftreibungen zusammen, die eine Dichte von 0,17 g/³ hatten.Nach 7–12 Wochen zeigte die Cytoplasmadichte eine progressive Zunahme auf 0,59 g/³ und die der Auftreibungen eine Zunahme auf 0,29 g/³.Das Volumen der Nervenzellen blieb ziemlich konstant.Die möglichen Zusammenhänge zwischen Zunahme der Dichte, Hypertrophie, Dystrophie und Hyperaktivität werden dargestellt.

Apolipoprotein E co-localizes with newly formed amyloid β-protein (Aβ) deposits lacking immunoreactivity against N-terminal epitopes of Aβ in a genotype-dependent manner

Different types of amyloid -protein (A)-containing plaques occur in brains of Alzheimers disease (AD) patients. Diffuse plaques seen during early stages of AD differ from neuritic plaques in later stages both with respect to the length of the A peptides and the presence of other proteins, e.g., apolipoprotein-E (apoE). Since apoE is involved in A transport and clearance, and the 4-allele of the apolipoprotein-E gene (APOE) is a major risk factor for sporadic AD, it is plausible to speculate that apoE plays a pathophysiological role in the initiation of A deposition. To address the issue of whether binding of apoE to A is involved in initial A deposition, we studied the human medial temporal lobe of 60 autopsy cases encompassing the full spectrum of AD-related pathology. In temporal lobe regions, which become involved for the first time at a given stage of -amyloidosis, all plaques represent newly formed plaques, and these were studied with immunohistochemical methods. ApoE was present in 36 cases, and was frequently co-localized with newly formed A deposits detectable with anti-A₄₂ but not with antibodies raised against N-terminal epitopes of A. In 10 additional cases, immunoreactivity against apoE was completely lacking in newly formed plaques, which, at the same time, displayed immunoreactivity against N-terminal epitopes of A. The failure of N-terminal epitopes of A to co-localize with apoE in newly formed plaques indicates that these deposits presumably contain apoE-A complexes, in which the N-terminal epitopes of A are often concealed after complexing with apoE, thus preventing subsequent binding of antibodies. Moreover, apoE-positive newly formed plaques were seen more frequently in APOE 4/4 cases than in non-APOE 4/4 individuals, thereby underlining the potentially crucial role of apoE for the development of A deposits.     

Utilization of acute inpatient psychiatric services: “Heavy users” in New York State

The severely and persistently mentally ill (SPMI) population are often forced to rely on emergency/acute inpatient services. The authors analyze Medicaid expenditures and state hospital utilization data to identify and describe the characteristics of heavy users of these services. Also described is New York State's intensive case management (ICM) initiative targeted at this heavy user group. It is postulated that ICM will alter the utilization patterns of participants from over-reliance on the most costly services and more effectively and efficiently serve the SPMI population, specifically the heavy user subpopulation.     

Gestalt- und erkenntnispsychologischer Beitrag zum melancholischen Wahn

Zusammenfassung Gestalt- und erkenntnispsychologische Zusammenhänge ergeben, daß dem melancholischen Wahn ein ametrisches Verhältnis der das menschliche Weltbild mitkonstituierenden Strukturtendenzen der Prägnanztendenz sowie des antiprägnanten Gestaltreizes der Welt zugrunde liegt. Dabei verstehen wir unter Weltbild die Erkenntnisgestalt der Welt, die vorweg (a priori) bestimmt, was je—individuell wirklich erkannt und verstanden wird. In der Melancholie kommt es nun durch eine Reduktion der Prägnanztendenz zu einem extrem einseitigen Bestimmtsein des Weltbildes durch den antiprägnanten Gestaltreiz der Welt. Die Folge dieser ametrischen Strukturiertheit des Weltbildes ist eine pathologische Wirklichkeitsgewißheit (Wahngewißheit) in allen Erkenntnisfunktionen also auch in der Vorstellung, in der Phantasie und in der Einbildung. Die Inhalte der melancholischen Wahnerlebnisse aber gehen auf den antiprägnanten Gestaltreiz der Welt zurück, der im Verlauf der normalen aktualgenetischen Entwicklung des Weltbildes zunehmend auf den Abbau und Zerfall der von der Prägnanztendenz intendierten Erkenntnisinhalte z. B. der immer intakten und integren Leib-, Ich- und Kommunikationsgestalt des Menschen aus ist, damit vom Erwachsenen auch Nichtintegres und Nichtintaktes sowie Zerfall in jeder Form verstanden und bewältigt werden kann. Die Gerichtetheit des antiprägnanten Gestaltreizes der Welt erkennt man in den melancholischen Wahnerlebnissen des Zerfalls des Leibes bis zur Verwesung bei lebendigem Leibe oder des Zerfalls der Ichgestalt bis zum nihuil unmittelbar wieder.Keine eindeutigen Aussagen jedoch erlauben unsere Beobachtungen über einen Wandel im Strukturverhältnis der Tendenz nach Wesenseigenschaften zur rein sachlichen Sinngehaltlichkeit der Individualgestalten in der Melancholie, während nach Matussek (1963) Wesenseigenschaften in der schizophrenen Wahrnehmungswelt einen Vorrang haben.     

Mental Hygiene of the Special Schools Teachers in Kerman,Iran

The goal of this research is to identify and study the mental hygiene and its related factors (individual, family, organizational) in the Kerman special schools teachers. 266 teachers of the special schools of the cities of the province Kerman were chosen as the research sample. The necessary data were obtained by questionnaire which its validity and reliability were determined. The statistical analysis of the research findings (by Spearman coefficient test) Man-Whithey and Kruskal wallis tests showed that there was a positive and meaningful relationship between Level of education, service of record the number of the members of teachers family, income, dwelling-place, economic power, acceptance of the teachers job in their family, leadership style, suitable educational possibilities, suitable educational space, job satisfaction with the mental hygiene of the teachers. The results of the research also showed that the Kerman special schools teachers enjoyed a relatively desirable mental hygiene.     

The protein composition of myelin in multiple sclerosis (MS) and orthochromatic leukodystrophy (OLD)

Summary In 4 cases of MS, in which the progression of disease differed, and in one case of infantile OLD the proteins of a homogenate and a myelin fraction with and without plaques were separated electrophoretically with polyacrylamide gels in a buffer system of phenol/formic acid/water. The relation of proteolipid protein to basic protein was estimated planimetrically and compared with control cases.In myelin from plaque material of chronic running MS cases an average decrease of 41% in basic protein was observed, while in an acute progressing case no obvious alterations could be discerned. Myelin from apparently normal MS white matter showed an average decrease of 13% in basic protein. The results of the OLD case were similar to those obtained from the chronic MS cases. The decrease of basic protein (chronic MS, OLD) was markedly more in the homogenate fraction than in the purified myelin. In a control case with autolytic alterations (autopsy after 24 hours) the content of basic protein was also diminished.Our findings indicate that the reduction of basic protein in myelin is a non-specific effect in demyelinating diseases.Presented in part at the Third International Meeting of the International Society for Neurochemistry, July 5–9th, 1971, Budapest.Supported by Deutsche Forschungsgemeinschaft (Sonderforschungsbereich 33), Stiftung Volkswagenwerk, and Forschungsmittel des Landes Niedersachsen.     

Team Leadership: Network Differences in Women's and Men's Instrumental and Expressive Relations

Recent studies have emphasised differences in leadership styles between women and men. Women have an interactive leadership style while men are more directive and authoritative. Social network analysis is used to examine differences in eight mental health case management teams, half formally supervised by women and half by men. The techniques used are graphical displays and measures of centrality. Results show male leaders as the most central team member for both instrumental and expressive relations. Female leaders, however, do not adhere to a single leadership style. Team centralisation also differs with gender composition of teams influencing leadership differences.     

The effect of non-response bias on the results of two-stage screening surveys of psychiatric disorder

Summary The effects are examined of two varieties of non-response bias (that due to illness and that due to defensiveness, as defined in this paper) on two-stage screening surveys for psychiatric disorder. Equations to model these effects are first derived; these are then used, in conjunction with pre-existing data, to estimate the sixe of the non-response bias. It is concluded (a) that bias due to illness results in prevalence estimates being some 5% lower than the true prevalence; (b) that specificity is little affected by either variety of bias; but that (c) bias due to defensiveness results in the sensitivity being overestimated by about 6%.     

Untersuchungen zum Aktivierungs- und Habituationsverhalten hirntraumatisch geschädigter Kinder und Jugendlicher unterschiedlichen Schweregrades

Zusammenfassung Das Ziel dieser Studie bestand in der Analyse des Aktivierungs- und Habituationsverhaltens hirntraumatisch geschädigter Jugendlicher in Abhängigkeit vom Schweregrad der Schädigung. Untersuchungsgruppen waren die i.S. einer Decerebration schwer hirngeschädigten Patienten mit Zustand nach apallischem Syndrom (N=9) sowie als Kontrollgruppe ein klinisches Klientel von N=10 Patienten mit Zustand nach leichter Hirnkontusion.Der Versuchreiz einer komplexen Reizdarbietung (optische und akustische Stimulation mit Reaktionserfordernis) bestand in einer täglich 4minütigen Dauerbelastungsphase am Wiener Determinationsgerät (n. Schuhfried). Dabei erfolgte eine kontinuierliche Registrierung der Herzfrequenz über 4 bzw. 8 Tage, wobei neben der physiologischen auch die psychisch-subjektive (Einschätzung der subjektiv erlebten Aktiviertheit) sowie die psychophysische (Leistungsquotient) Meßebene analysiert wurden, um aus der möglichen Wechselwirkung konkrete Rehabilitationsmaßnahmen ableiten zu können.Die Befunde zeigten bei allen Variablen eine klare Differenzierung zwischen den Patientengruppen: die Analyse der Herzfrequenz ergab, daß trotz gleichen Ausgangsniveaus der Aktiviertheit nur bei der Kontrollgruppe eine initiale Sensibilisierungsreaktion auftrat, die sich im Laufe der Reizwiederholung i. S. einer Habituation verminderte.Bei einer deskriptiven Analyse der HR-Verläufe in Form von mathematischen Exponentialfunktionen zeigte es sich, daß sich im wesentlichen drei relativ stabile Reaktionstypen abzeichneten, nämlich sog. Sensibilisierer, Habituierer sowie Indifferenztypen, wobei die Habituierer nur bei der Kontrollgruppe, die Indifferenztypen hingegen nur bei den apallisch geschädigten Patienten auftraten.Die Untersuchung der Wechselwirkung verschiedener Meßebenen legt eine gewisse Entkoppelung funktioneller Systeme, wie sie u.a. von Luria (1976) beschrieben werden, bei apallisch geschädigten Patienten nahe, wobei unter dem Versuchsreiz sensomotorische und physiologische Systeme offensichtlich nicht in einer optimal aufeinander abgestimmten Weise ablaufen, wie dies überwiegend bei den nur leicht hirngeschädigten Vergleichspatienten gefunden wurde.Hieraus resultierende Rehabilitationsmaßnahmen werden erörtert.Die hier zitierten experimentellen Untersuchungen stammen aus dem Teilprojekt D7 des SFB 122 an der Universität Marburg/Lahn unter Leitung von Prof. Dr. Dr. H.

Quantification of motor deficit in Parkinson's disease with a motor performance test series

Summary It was the purpose of the present study to quantify the expected motor deficit in parkinsonian patients with the computer assisted Motor Performance Test Series (MPS), version 05.87 by Schuhfried (1987) and to examine which of the motor test variables found correlate at a significance level of p<0.01 with items of motor examination recorded at neurological examination and activities of daily living of the Unified Parkinson's Disease Rating Scale (UPDRS), version 3.0.38 patients with idiopathic Parkinson's disease (PD) stages I–IV according to Hoehn and Yahr, aged 41 to 73 years were studied. The study design, i.e. initial rating by the physician followed immediately by testing of motor function with MPS was strictly adhered to in each patient.Physician's rating of rigor and the scores of the semiquantitative tests (finger taps, hand movements and alternating movements) as expression of hypokinesia and the activities of daily living correlated with the 3 factors of the Motor Performance Test Series at a highly significant level independent of disease stage. Tremor is only partly and never significantly reflected in the motor data measured. Stages I–II and II–IV (Hoehn and Yahr) differ significantly in the representative data of the Motor Performance Test Series.The results of the study support the assumption that MPS is a valid instrument for quantitative measurement of the motor deficit in parkinsonian patients, but that only some subtests are pathognomonic.     

Colocalization of prion protein and β protein in the same amyloid plaques in patients with Gerstmann-Sträussler Syndrome

Summary We examined paraffin-embedded brain sections from three patients with Creutzfeldt-Jakob disease (CJD) and four patients with Gerstmann-Sträussler syndrome (GSS) who also had protein deposits in the brains. Immunostaining using anti-prion protein (PrP) and anti- protein coupled with formic acid pretreatment, revealed PrP deposits and protein deposits, respectively. In all four GSS patients examined, sequential double immunostaining and single immunostaining in serial sections or simultaneous double immunofluorescence revealed the colocalization of PrP and protein in the same amyloid plaques. The plaques labeled with both antibodies were designated as -PrP plaques. Small kuru plaques of less than 15 m in diameter were rarely found to coexist with deposits. The percentages of -PrP plaques in larger kuru plaques were not constant among the four GSS patients. The colocalization patterns of both deposits were observed as being roughly of two types as follows: (1) diffuse protein deposits located around the PrP core; and (2) a protein core and PrP core simultaneously existing in one amyloid plaque. Under an electron microscope, we were able to confirm the presence of both protein and PrP in a single plaque in four GSS patients older than 60 years old. In contrast, no colocalization of either deposits was seen in the amyloid plaque core fractions of a young GSS patient who had no protein deposits, even at the electron microscopic level. Therefore, the colocalization of both proteins in a single plaque is believed to be age-related and incidental in GSS patients but suggests a similar morphogenesis of both amyloid deposits.Supported in part by a Grant-in-Aid for Scientific Research (02454245, 03454171) from the Ministry of Education, Science and Culture of Japan     

Coping with stress as a theme in teaching psychopathology to medical students

In an era when non-psychiatric physicians are increasingly aware of their need for at least a rudimentary knowledge of psychology, medical schools are making belated attempts to remedy the situation.The effort described here succeeded because the students did not seem to view the course as one about crazy people. Thus, they did not distance themselves from the course material and patients.... One student said, This was a course about everybody—about what people have to do to live in the world.     

Zum Problem der sogenannten Simultanagnosie

Zusammenfassung Bei einem Patienten mit einem vorzugsweise lobär verlaufenden hirnatrophischen Prozeß wurden die Störungen der Gesamtauffassung bildlich dargestellter Situationen (Simultanagnosie), die er neben Wortfindungsschwierigkeiten, Paraphasien, Dysgraphie, Dyskalkulie und Merkschwäche bot, einer Analyse unterzogen. Die gestörte Intellektualität der Wahrnehmung zeigte sich als ein Darniederliegen ihrer sinngerichteten Aktivität. Der Patient war nicht in der Lage, Strukturen in eine Wahrnehmungsgegebenheit zu bringen, war unfähig, eine Gestalt aufzubauen. Durch Störungen des Übersehens hatte die Überschaubarkeit des Wahrnehmungsfeldes gelitten. Bei schneller Absättigung des Sinnfindungsbedürfnisses kam es zum sinngemäßen Illusionieren innerhalb kurzschlüssig hergestellter Sinneinheiten. Die durch das Zurücktreten der Gestalt gegenüber der Physiognomie des Gegenstandes gekennzeichneten Zeichnungen des Patienten wurden den raumagnastischen Gestaltungsstörungen zugeordnet. Die Bedeutung der Störungen für das Leben des Patienten erhellen sein Verzicht auf Wahrnehmung und seine Unsicherheit gegenüber einer eindringlicher gewordenen, nicht mehr dahingestellten Welt.
