Cruveilhier's legacy to skull base surgery: premise of an evidence-based neuropathology in the 19th century.

OBJECTIVES: Jean Cruveilhier has always been described as a pioneer in pathological anatomy. Almost nothing has been reported concerning his exceptional methodology allying pre-mortem clinical description and syndromic classification of neurological and neurosurgical diseases, and post-mortem meticulous dissections. Cruveilhier's methodology announced the birth of the anatomoclinical method built up by Jean-Martin Charcot and the neurological French school during the 19th century. The aim of our work is to extract the quintessence of Cruveilhier's contributions to skull base pathology through his cogent clinical descriptions coupled with exceptional lithographs of anterior skull base, suprasellar and cerebello-pontine angle tumors. METHODS: We reviewed the masterwork of Jean Cruveilhier on pathological anatomy and we selected the chapters dedicated to central nervous system pathologies, mainly skull base diseases. A systematic review was performed on Pubmed/Medline and Google Scholar using the keywords "Jean Cruveilhier", "Skull base pathology", "Anatomoclinical method". RESULTS: Among his descriptions, Cruveilhier dedicated large chapters to neurosurgical diseases including brain tumors, cerebrovascular pathologies, malformations of the central nervous system, hydrocephalus, brain infections and spinal cord compressions. CONCLUSION: This work emphasizes on the role of Jean Cruveilhier in the birth of the anatomoclinical method particularly in neuroscience during a 19th century rich of epistemological evolutions toward an evidence-based medicine, through the prism of Cruveilhier's contribution to skull base pathology.

"We are all middle class: On the subjective status in Chile"

Chile is one of the countries with the highest level of income inequality worldwide. Given the association between economic inequality and patterns of social stratification, in such context it would be expected to find a large dispersion of subjective social status' indicators in the population. Nevertheless, analyses from international surveys reveal a strong tendency to the mean of the subjective status i.e. there would be downward and upward biases of the subjective status regarding the objective status. The present research attempts to tackle this phenomenon for the Chilean case, with a focus on the influence of status and class variables on the subjective status. For the analysis we use Chilean data from the social inequality module of the International Social Survey Programme 2009. The results indicate a strong tendency to the mean of the subjective status in the population, particularly from the side of those with higher objective status.

Kinship, ritual kinship and political milieus in an alpine Valley in 19th century

In my paper I will present some results about ritual kinship and political mobilization of popular groups in an alpine Valley: the Val de Bagnes, in the Swiss canton of Valais. There are two major reasons to choose the Val de Bagnes for our inquiry about social networks: the existence of sharp political and social conflicts during the 18th and the 19th century and the availability of almost systematic genealogical data between 1700 and 1900. The starting point of my research focuses on this question: what role did kinship and ritual kinship play in the political mobilization of popular groups and in the organization of competing factions? This question allows us to shed light on some other uses and meanings of ritual kinship in the local society. Was ritual kinship a significant instrument for economic cooperation? Or was it a channel for patronage or for privileged social contacts? The analysis highlights the importance of kinship and godparentage for the building of homogeneous social and political networks. If we consider transactions between individuals, the analysis of 19th century Val de Bagnes gives the impression of quite open networks. Men and women tried to diversify their relations in order to avoid strong dependency from powerful patrons. Nevertheless, when we consider the family networks, we can notice that most relations took place in a structured social space or a specific "milieu", were intense contacts enhanced trust, although political allegiances and social choices were not fully predictable on the basis of such preferential patterns. In a politically conflictual society, like 19th century Bagnes, ritual kinship interacted with kinship solidarities and ideological factors shaping dense social networks mostly based on a common political orientation. Such milieus sustained the building of political factions, which show surprising stability over time. In this sense, milieus are important factors to understand political and religious polarization in 19th century Switzerland.

Timing History: The Introduction of Graphical Analysis in 19th Century British Economics

The introduction of time-series graphs into British economics in the 19th century depended on the « timing » of history. This involved reconceptualizing history into events which were both comparable and measurable and standardized by time unit. Yet classical economists in Britain in the early 19th century viewed history as a set of heterogenous and complex events and statistical tables as giving unrelated facts. Both these attitudes had to be broken down before time-series graphs could be brought into use for revealing regularities in economic events by the century's end.

Jeunes filles scoliotiques et orthopédie a la Belle Epoque: l'essor urbain de la mécanothérapie a Lausanne et Genève [Scoliotic young girls and orthopaedics in Belle Epoque: the urban surge of mecanotherapy in Lausanne and Geneva].

In Belle Epoque towns marked by the industrial and medical surge, a new technical therapy, called mechanotherapy, emerged, stemming from Swedish medical gymnastics and auxiliary to orthopaedics. Aiming mostly at treating scoliosis, this therapy by movement attracted a sizeable female clientele to these towns, because of the hygienic and social conceptions feeding collective imagination linked to the bodies of scoliotic young girls. Taking the French-speaking Swiss towns of Lausanne and Geneva as examples, the article first seeks to describe the emergence of mechanotherapy as a medical and urban phenomenon. It then addresses the role played by scoliosis in this orthopaedic practice, and examines the clientele attracted to the towns, among which well-born young girls seem to be predominant.

Nineteenth century research on cell death.

This paper reviews research on cell death in the 19th C. The first report of cell death was by Vogt in 1842, which was remarkably soon after the establishment of the cell theory by Schleiden and Schwann between 1838 and 1842. Initial studies on cell death, including that of Vogt, focused on its occurrence in metamorphosis (Vogt, 1842; Prévost and Lebert, 1844; Weismann, 1863-1866) or in blatant pathology (Virchow, 1858), but as histological techniques improved it was found to be involved in more subtle roles in numerous situations including endochondral ossification (Stieda, 1872), ovarian follicle atresia (Flemming, 1885), cell turnover (Nissen, 1886), the wholesale loss of a population of sensory neurons in fish (Beard, 1889), and the naturally occurring histogenetic death of myocytes (Felix, 1889) and neurons (Collin, 1906). The current categorization of cell death into about three main morphological types has 19th century roots in that apoptosis was well described by Flemming (1885), who called it chromatolysis, and various authors including Noetzel (1895) proposed a threefold classification. This article is part of a Special Issue entitled "Apoptosis: Four Decades Later".

Videvdad 19 : édition critique, traduction et commentaires des textes avestique et moyen-perse

Notre travail porte sur le Videvdad, texte avestique nommé d'après unmot avestique Videvdad-data-, c'est-à-dire la « Un qui tient éloignés les demons ». Ce recueil comprend 22 chapitres édictant des lois religieuses, des préceptes rituels et des mesures de purification Ces prescriptions ont pour but de repousser l'impureté des elements purs de la création d'Ahura Mazda. Notre thèse est une édition du chapitre 19 de ce recueil complétée de sa traduction commentée. Ce chapitre raconte la tentation de Zarathustra par le Mauvais Esprit et sa victoire sur ce dernier Le texte a été traduit et commenté sémantiquement, phonétiquement et philologiquement afin d'en dégager les particularités linguistiques.L'édition de référence du texte avestique est celle de Geldner, qui date de la fin du 19 siècle Dans la mesure où il a été démontré durant ces dernières années quil fallait revoir ce travail, nous avons fait une édition du texte en collationnant 13 manuscits. Notre étude nous a permis à la fois de proposer pour certains termes une autre lecture que celle de Geldner et decontinuer les recherches sur la filiation des manuscrits.De plus le texte avestique a été mis en regard de la version pehlevie. L'intérêt de cette dernière traduction réside dans ses gloses : parfois un long commentaire parfois une simple énonciation de synonymes en pehlevie. le traducteur lui-même comprenant mal le sens du mot original. L'édition du texte pehlevi a également été refaite à partir des deux manuscrits lesplus anciens (L4 et Kl).Videvdad 19 :Critical Edition, Translation and Commentary of the Avestan and Pahlavi TextsWe worked on the Videvdad, an Avestan text whose title is a Middle Persian word coming from the Avestan Videvdad-data- "the law that keeps demons away" This anthology contains 22 chapters dealing with religious laws, ritual precepts and measures of purification. These prescriptions aim ft rejecting impurity from pure elements in Ahura Mazda's creation. Our dissertation is an edition and translation with commentary of chapter 19 of this anthology. lt relates the temptation of Zarathustra by the Bad Evil and how Zarathustra overcame him. The text was translated and annotated semantically, phonetically and philologically to highlight linguistic features.Until today, Geldner's edition, which dates back to the end of the 19th century has been the edition of reference. However, in recent years, scholars have shown that this edition must be revised Therefore, we prepared an edition of the Avestan text by collating 13 manuscripts. This work led us to propose new readings for several words and pursue research onmanuscripts filiation.Furthermore, we also studied the Middle Persian text. This translation is interesting in that it contains glosses that can either be long commentaries or simple synonyms. We also made the edition of the Middle Persian text on the basis of the two oldest manuscripts (L4 and Kl).

Novel anesthetics and other treatment strategies for refractory status epilepticus

Refractory status epilepticus (RSE)-that is, seizures resistant to at least two antiepileptic drugs (AEDs)-is generally managed with barbiturates, propofol, or midazolam, despite a low level of evidence (Rossetti, 2007). When this approach fails, the need for alternative pharmacologic and nonpharmacologic strategies emerges. These have been investigated even less systematically than the aforementioned compounds, and are often used, sometimes in succession, in cases of extreme refractoriness (Robakis & Hirsch, 2006). Several possibilities are reviewed here. In view of the marked heterogeneity of reported information, etiologies, ages, and comedications, it is extremely difficult to evaluate a given method, not to say to compare different strategies among them. Pharmacologic Approaches Isoflurane and desflurane may complete the armamentarium of anesthetics,' and should be employed in a ''close'' environment, in order to prevent intoxication of treating personnel. c-Aminobutyric acid (GABA)A receptor potentiation represents the putative mechanism of action. In an earlier report, isoflurane was used for up to 55 h in nine patients, controlling seizures in all; mortality was, however, 67% (Kofke et al., 1989). More recently, the use of these inhalational anesthetics was described in seven subjects with RSE, for up to 26 days, with an endtidal concentration of 1.2-5%. All patients required vasopressors, and paralytic ileus occurred in three; outcome was fatal in three patients (43%) (Mirsattari et al., 2004). Ketamine, known as an emergency anesthetic because of its favorable hemodynamic profile, is an N-methyl-daspartate (NMDA) antagonist; the interest for its use in RSE derives from animal works showing loss of GABAA efficacy and maintained NMDA sensitivity in prolonged status epilepticus (Mazarati & Wasterlain, 1999). However, to avoid possible neurotoxicity, it appears safer to combine ketamine with GABAergic compounds (Jevtovic-Todorovic et al., 2001; Ubogu et al., 2003), also because of a likely synergistic effect (Martin & Kapur, 2008). There are few reported cases in humans, describing progressive dosages up to 7.5 mg/kg/h for several days (Sheth & Gidal, 1998; Quigg et al., 2002; Pruss & Holtkamp, 2008), with moderate outcomes. Paraldehyde acts through a yet-unidentified mechanism, and appears to be relatively safe in terms of cardiovascular tolerability (Ramsay, 1989; Thulasimani & Ramaswamy, 2002), but because of the risk of crystal formation and its reactivity with plastic, it should be used only as fresh prepared solution in glass devices (Beyenburg et al., 2000). There are virtually no recent reports regarding its use in adults RSE, whereas rectal paraldehyde in children with status epilepticus resistant to benzodiazepines seems less efficacious than intravenous phenytoin (Chin et al., 2008). Etomidate is another anesthetic agent for which the exact mechanism of action is also unknown, which is also relatively favorable regarding cardiovascular side effects, and may be used for rapid sedation. Its use in RSE was reported in eight subjects (Yeoman et al., 1989). After a bolus of 0.3 mg/kg, a drip of up to 7.2 mg/kg/h for up to 12 days was administered, with hypotension occurring in five patients; two patients died. A reversible inhibition of cortisol synthesis represents an important concern, limiting its widespread use and implying a careful hormonal substitution during treatment (Beyenburg et al., 2000). Several nonsedating approaches have been reported. The use of lidocaine in RSE, a class Ib antiarrhythmic agent modulating sodium channels, was reviewed in 1997 (Walker & Slovis, 1997). Initial boluses up to 5 mg/kg and perfusions of up to 6 mg/kg/h have been mentioned; somewhat surprisingly, at times lidocaine seemed to be successful in controlling seizures in patients who were refractory to phenytoin. The aforementioned dosages should not be overshot, in order to keep lidocaine levels under 5 mg/L and avoid seizure induction (Hamano et al., 2006). A recent pediatric retrospective survey on 57 RSE episodes (37 patients) described a response in 36%, and no major adverse events; mortality was not given (Hamano et al., 2006 Verapamil, a calcium-channel blocker, also inhibits P-glycoprotein, a multidrug transporter that may diminish AED availability in the brain (Potschka et al., 2002). Few case reports on its use in humans are available; this medication nevertheless appears relatively safe (under cardiac monitoring) up to dosages of 360 mg/day (Iannetti et al., 2005). Magnesium, a widely used agent for seizures elicited by eclampsia, has also been anecdotally reported in RSE (Fisher et al., 1988; Robakis & Hirsch, 2006), but with scarce results even at serum levels of 14 mm. The rationale may be found in the physiologic blockage of NMDA channels by magnesium ions (Hope & Blumenfeld, 2005). Ketogenic diet has been prescribed for decades, mostly in children, to control refractory seizures. Its use in RSE as ''ultima ratio'' has been occasionally described: three of six children (Francois et al., 2003) and one adult (Bodenant et al., 2008) were responders. This approach displays its effect subacutely over several days to a few weeks. Because ''malignant RSE'' seems at times to be the consequence of immunologic processes (Holtkamp et al., 2005), a course of immunomodulatory treatment is often advocated in this setting, even in the absence of definite autoimmune etiologies (Robakis & Hirsch, 2006); steroids, adrenocorticotropic hormone (ACTH), plasma exchanges, or intravenous immunoglobulins may be used alone or in sequential combination. Nonpharmacologic Approaches These strategies are described somewhat less frequently than pharmacologic approaches. Acute implantation of vagus nerve stimulation (VNS) has been reported in RSE (Winston et al., 2001; Patwardhan et al., 2005; De Herdt et al., 2009). Stimulation was usually initiated in the operation room, and intensity progressively adapted over a few days up to 1.25 mA (with various regimens regarding the other parameters), allowing a subacute seizure control; one transitory episode of bradycardia/asystole has been described (De Herdt et al., 2009). Of course, pending identification of a definite seizure focus, resective surgery may also be considered in selected cases (Lhatoo & Alexopoulos, 2007). Low-frequency (0.5 Hz) transcranial magnetic stimulation (TMS) at 90% of the resting motor threshold has been reported to be successful for about 2 months in a patient with epilepsia partialis continua, but with a weaning effect afterward, implying the need for a repetitive use (Misawa et al., 2005). More recently, TMS was applied in a combination of a short ''priming'' high frequency (up to 100 Hz) and longer runs of low-frequency stimulations (1 Hz) at 90-100% of the motor threshold in seven other patients with simple-partial status, with mixed results (Rotenberg et al., 2009). Paradoxically at first glance, electroconvulsive treatment may be found in cases of extremely resistant RSE. A recent case report illustrates its use in an adult patient with convulsive status, with three sessions (three convulsions each) carried out over 3 days, resulting in a moderate recovery; the mechanism is believed to be related to modification of the synaptic release of neurotransmitters (Cline & Roos, 2007). Therapeutic hypothermia, which is increasingly used in postanoxic patients (Oddo et al., 2008), has been the object of a recent case series in RSE (Corry et al., 2008). Reduction of energy demand, excitatory neurotransmission, and neuroprotective effects may account for the putative mechanism of action. Four adult patients in RSE were cooled to 31_-34_C with an endovascular system for up to 90 h, and then passively rewarmed over 2-50 h. Seizures were controlled in two patients, one of whom died; also one of the other two patients in whom seizures continued subsequently deceased. Possible side effects are related to acid-base and electrolyte disturbances, and coagulation dysfunction including thrombosis, infectious risks, cardiac arrhythmia, and paralytic ileus (Corry et al., 2008; Cereda et al., 2009). Finally, anecdotic evidence suggests that cerebrospinal fluid (CSF)-air exchange may induce some transitory benefit in RSE (Kohrmann et al., 2006); although this approach was already in use in the middle of the twentieth century, the mechanism is unknown. Acknowledgment A wide spectrum of pharmacologic (sedating and nonsedating) and nonpharmacologic (surgical, or involving electrical stimulation) regimens might be applied to attempt RSE control. Their use should be considered only after refractoriness to AED or anesthetics displaying a higher level of evidence. Although it seems unlikely that these uncommon and scarcely studied strategies will influence the RSE outcome in a decisive way, some may be interesting in particular settings. However, because the main prognostic determinant in status epilepticus appears to be related to the underlying etiology rather than to the treatment approach (Rossetti et al., 2005, 2008), the safety issue should always represent a paramount concern for the prescribing physician. Conclusion The author confirms that he has read the Journal's position on issues involved in ethical publication and affirms that this paper is consistent with those guidelines.

The class basis of the cleavage between the New Left and the radical right: An analysis for Austria, Denmark, Norway and Switzerland

This chapter argues that the electoral competition between the New Left and the Radical Right is best understood as a cultural divide anchored in different class constituencies. Based on individual-level data from the European Social Survey, we analyze the links between voters' class position, their economic and cultural preferences and their party choice for four small and affluent European countries. We find a striking similarity in the class pattern across countries. Everywhere, the New Left attracts disproportionate support from socio-cultural professionals and presents a clear-cut middle-class profile, whereas the Radical Right is most successful among production and service workers and receives least support from professionals. In general, the Radical Right depends on the votes of lowereducated men and older citizens and has turned into a new type of working-class party. However, its success within the working-class is not due to economic, but to cultural issues. The voters of the Radical Right collide with those of the New Left over a cultural conflict of identity and community - and not over questions of redistribution. A full-grown cleavage has thus emerged in the four countries under study, separating a libertarian-universalistic pole from an authoritarian-communitarian pole and going along with a process of class realignment.

New York City: "gilt cage" or "promised land" ? : representations of urban space in Edith Wharton and Anzia Yezierska

This thesis explores the importance of literary New York City in the urban narratives of Edith Wharton and Anzia Yezierska. It specifically looks at the Empire City of the Progressive Period when the concept of the city was not only a new theme but also very much a typical American one which was as central to the American experience as had been the Western frontier. It could be argued, in fact, that the American city had become the new frontier where modern experiences like urbanization, industrialization, immigration, and also women's emancipation and suffrage, caused all kinds of sensations on the human scale from smoothly lived assimilation and acculturation to deeply felt alienation because of the constantly shifting urban landscape. The developing urban space made possible the emergence of new female literary protagonists like the working girl, the reformer, the prostitute, and the upper class lady dedicating her life to 'conspicuous consumption'. Industrialization opened up city space to female exploration: on the one hand, upper and middle class ladies ventured out of the home because of the many novel urban possibilities, and on the other, lower class and immigrant girls also left their domestic sphere to look for paid jobs outside the home. New York City at the time was not only considered the epicenter of the world at large, it was also a city of great extremes. Everything was constantly in flux: small brownstones made way for ever taller skyscrapers and huge waves of immigrants from Europe pushed native New Yorkers further uptown on the island, adding to the crowdedness and intensity of the urban experience. The city became a polarized urban space with Fifth Avenue representing one end of the spectrum and the Lower East Side the other. Questions of space and the urban home greatly mattered. It has been pointed out that the city setting functions as an ideal means for the display of human nature as well as social processes. Narrative representations of urban space, therefore, provide a similar canvas for a protagonist's journey and development. From widely diverging vantage points both Edith Wharton and Anzia Yezierska thus create a polarized city where domesticity is a primal concern. Looking at all of their New York narratives by close readings of exterior and interior city representations, this thesis shows how urban space greatly affects questions of identity, assimilation, and alienation in literary protagonists who cannot escape the influence of their respective urban settings. Edith Wharton's upper class "millionaire" heroines are framed and contained by the city interiors of "old" New York, making it impossible for them to truly participate in the urban landscape in order to develop outside of their 'Gilt Cages'. On the other side are Anzia Yezierska's struggling "immigrant" protagonists who, against all odds, never give up in their urban context of streets, rooftops, and stoops. Their New York City, while always challenging and perpetually changing, at least allows them perspectives of hope for a 'Promised Land' in the making. Central for both urban narrative approaches is the quest for a home as an architectural structure, a spiritual resting place, and a locus for identity forming. But just as the actual city embraces change, urban protagonists must embrace change also if they desire to find fulfillment and success. That this turns out to be much easier for Anzia Yezierska's driven immigrants rather than for Edith Wharton's well established native New Yorkers is a surprising conclusion to this urban theme.

Geografia associativa e imperialismo svizzero. Il caso di Ginevra (1858-1914)

ASSOCIATIVE GEOGRAPHY AND SWISS IMPERIALISM. THE EXAMPLE OF GENEVA (1858-1914) − This article is about geographical society of Geneva and its involvement in the 19th century colonial imperialism. Through this society, Swiss bourgeoisie takes part in the exploration and colonization of the world. Is this participation a sign of Swiss imperialism? This issue will be at the heart of this study.

Sex, politics and social change in the eighteenth and the nineteenth centuries: Evidence from the Swiss Alps

The 18th century "sexual revolution" can not simply be explained as a consequence of economic or institutional factors - industrialization, agricultural revolution, secularization or legal hindrances to marriages: the example of western Valais (Switzerland) shows that we have to deal with a complex configuration of factors The micro-historical approach reveals that in the 18th and 19th century sexuality - and above all illicit sexuality - was a highly subversive force which was considerably linked to political innovation and probably more generally to historical change. Non-marital sexuality was clearly tied to political dissent ant to innovative ways of behaviour, both among the social elites and the common people. This behaviour patterns influenced crucial evolutions in the social, cultural and economic history of the region.
