About medicine and the arts. Charcot and French literature at the fin-de-siècle.

Koehler, P

The relationship between medicine and the arts, literature in particular, has many aspects. One of the most obvious relations is the use of literature as a source for historical studies. Jean-Martin Charcot and his school often appear in French literature at the end of the 19th century. Several aspects will be highlighted in this study, including (1) the ideas about degenerative diseases in the work of Emile Zola, the main author of the naturalistic movement; (2) decadence and spiritism in two "transitional" novels by Joris Karl Huysmans, who, once supporter of the naturalistic movement, changed his ideas following observations of disease and cure that could not be explained in a scientific way. Charcot's work on hysteria and hypnosis, as well as Brown-Séquard's rejuvenation experiments with testicular extracts played an important role with this respect; (3) Charcot's relationship with the Daudets, in particular his treatment of Alphonse's tabes dorsalis and the ambivalent attitude of his son Léon Daudet towards Charcot; (4) the influence of the lectures at the Salpêtrière on the work of Guy de Maupassant, who attended the lessons in the mid-1880s. The reading of novels and biographies of these authors provides a part of the social context and the cultural atmosphere in Paris at the "fin-de-siècle" when Charcot and his school played an important role in medicine. Moreover, it shows the influence of medicine and science on society as recorded by writers.

Jean-Anthelme Brillat-Savarin's 1825 treatise on the mouth and ingestion.

PubMed

Chong, Gabriel Tse Feng

2012-12-01

This article quotes and discusses Jean-Anthelme Brillat-Savarin's musings on the mouth and ingestion as described in his book The Physiology of Taste. The book was first published in France in December 1825, and is still widely read as a key work in Gastronomy today. The mouth is intimately related to the acts of chewing, swallowing and eating and it would be interesting to report an early 19th century epicurean's views on the mouth. Passages from Brillat-Savarin's book describing the functions of the teeth and tongue and the acts of tasting, chewing, and swallowing are quoted in full. Anecdotes also include one on the horrifying punishment of having one's tongue removed and another illustrating the poor oral health found among Europeans of that era. His work offers a unique glimpse into how a 19th century gastronome viewed the oral cavity and its gastronomical functions. While some of his writings may appear archaic and antediluvian to the modern reader; others relating to, for example chewing and swallowing, are surprisingly accurate by contemporary standards. Nonetheless, the gastronomic savant seemed to know a lot right about modern stomatology! Copyright © 2012. Published by Elsevier B.V.

[The tribute of the pioneer of hypnotherapy--Franz Anton Mesmer, MD, PhD in the history of psychotherapy and medicine].

PubMed

Radovancević, Ljubomir

2009-01-01

Modern hypnosis started with the Austrian physician Franz Anton Mesmer (1734-1815), who believed that the phenomenon known as mesmerism, or animal magnetism, or fluidum was related to an invisible substance--a fluid that runs within the subject or between the subject and the therapist, that is, the hypnotist, or the "magnetizer". The term hypnosis was introduced in the 1840s by a Scottish surgeon James Braid (1795-1860), who believed the subject to be in a particular state of sleep--a trance. In the late 19th century, a French neurologist Jean Martin Charcot (1825-1893) thought hypnotism to be a special physiological state, and his contemporary Hyppotite-Marie Bernheim (1840-1919) believed it to be a psychological state of heightened suggestibility. Sigmund Freud, who studied with Charcot, used hypnosis early in his career to help patients recover repressed memories. He noted that patients would relive traumatic events while under hypnosis, a process know as abreaction. Freud later replaced hypnosis with the technique of free associations. Today, hypnosis is used as a form of therapy (hypnotherapy), a method of investigation to recover lost memories, and research tool. According to Caplan & Sadock, F.A. Mesmer is generally thought of as the fons et origo of modern psychotherapy; and from the early techniques of mesmerism, it is said, have evolved the more elaborate and sophisticated therapeutic measures of the analyst and his colleagues. Although Mesmer was certainly dealing with individuals suffering from a variety of neurotic disorders, and though the clinical successes he achieved were the result of psychological processes that his procedures induced in his patients, Mesmer's theoretical formulations, his understanding of the nature of the treatment he developed, and his specific procedures were all totally different from those of the 20th century analyst. He was one of the corne stones in the development of psychoanalysis through hypnosis mainly of hysterical

[Fatal diseases and "imaginary" suffering. "Hypochondria" and "consumption" in the correspondence between Jean Paul and Johann Bernhard Hermann, with a perspective on Jean Paul's literature and aesthetics].

PubMed

Meier, Monika

2007-01-01

The German writerJean Paul (Johann Paul Friedrich Richter, 1763-1825) and his friendJohann Bernhard Hermann (1761-1790) became acquainted with the thoughts of late Enlightenment at the University of Leipzig. They particularly appreciated the anthropology of Ernst Platner, who taught philosophy and aesthetics as well as medicine. Their confidential correspondence contains reflections on their respective situation and well being. Both write about feeling ill and label their illness "hypochondria". In the course of the correspondence Jean Paul's understanding of hypochondria evolves from an illness of the entrails as he follows Hermann, who supports the modern concept of hypochondria as an illness of the nerves. Two important themes from this correspondence recur in Jean Paul's novels and tales: firstly, his way of expressing comfort is related to his aesthetics, and secondly, the satirical way of portraying at least certain aspects of illness as imaginary reappears in his first successful novel "The Invisible Lodge" (1793).

2012-04-01

We present a short historical review of the major figures, their administrative functions and their works that contributed to make Paris a renowned centre of physiology and neurology during the xixth and the first half of the xxth century. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the actual beginning of neurosciences, and 1950 marks their exponential rise. Our presentation is divided into four chapters, matching the main disciplines which have progressed and contributed the most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the third of four parts of this review, and deals with neurology. A special credit should be given to Jean-Martin Charcot who founded the Salpêtrière School of neurology and became one of the world's most important neurologists of the xixth century. We provide below the biographical sketches of Armand Trousseau, Guillaume Benjamin Amand Duchenne, Jean-Martin Charcot, Alfred Vulpian, Désiré-Magloire Bourneville, Paul Richer, Henri Parinaud, Albert Pitres, Jules Joseph Dejerine, Mrs. Augusta Dejerine-Klumpke, Édouard Brissaud, Pierre Marie, Georges Édouard Brutus Gilles de la Tourette, Joseph Babinski, André Thomas, Georges Marinesco, Achille Alexandre Souques, Georges Guillain and Charles Foix.

[Charcot and hysteria].

PubMed

Widlöcher, D; Dantchev, N

1994-01-01

Charcot's work on hysteria has always been controversial. All his attitudes, whether on the theory of the ovary, the hysteroepileptic seizure or the use of hypnosis, have always been charicatured, misunderstood and separated from the wider context of his overall approach. Rereading Charcot's works shows that he developed his approach progressively over a period of more than 20 years before coming to his psychological model of hysteria. This model explains the formation of the symptom and the hysterical conversion via a mechanism of being ignorant of the motor representation. This concept has never been disproven and remains the only theory explaining the formation of the hysteria symptom. Based on Charcot's fundamental contribution, Freud and Janet further developed their work on the psychopathology of hysteria.

Gilles de la Tourette's criminal women: the many faces of fin de siècle hypnotism.

Bogousslavsky, Julien; Walusinski, Olivier

2010-09-01

Gilles de la Tourette is now known for the disease which now bears his name, but his activities in the management of hysterics and in hypnotism, which gained him most of his lifetime reputation, have been largely forgotten. As one of the closest followers of Jean-Martin Charcot, he always remained faithful to his mentor's views, and was one of the most vehement defenders of La Salpêtrière school during the quarrel with Hippolyte Bernheim and the Nancy school on the question of the specificity of hypnotic susceptibility in hysteria. This controversy became critical during medico-legal assessment of crimes supposedly committed under hypnotic suggestion. Gilles de la Tourette's involvement in criminal hypnotism was striking, as shown by his own experiments, the most famous of which being his suggested poisoning of a colleague by Blanche Wittman, the celebrated Charcot's hysteric patient in the 1887 Brouillet's painting. Gilles de la Tourette also acted as expert in murder trials, and his Epilogue in the Gouffé's trunk case, where he affirmed that no murder in real life could be due to hypnotism, and considered that Gabrielle Bompard, the murderer's accomplice, was not under hypnotic suggestion, had a considerable impact. Finally, he was confronted to the issue of murder under hypnotism in his private life, since in 1893, a former patient, Rose Kamper, came and shot him in the head at his home, claiming that hypnotism sessions had changed her own person, and that she had been hypnotized "at distance". These acts from three very different "hysterical" women highlight the Salpêtrière's theories on hypnotism and their inner contradictions in the fin de siècle ambiance, a few years before Joseph Babinski renewed the concepts on hysteria.

-speaking universities in Central Europe. In France, important advances were once again initiated in Paris by Jean-Martin Charcot (1825-1893) and some of his pupils who renewed the concept of hysteria and the use of hypnosis. Sainte-Anne Hospital was created in 1867. This new institution located in the southern part of Paris became (and is still) one of the most important places in France for the treatment, research and teaching of mental diseases. Thereafter started new disciplines such as clinical psychology and neuropsychology; the scientific basis of psychology and notably the psychopathology hypothesis were established. A major revolutionary step occurred in Paris in the early 1950s with the discovery of neuroleptics and the birth of psychopharmacology. Here we present the biographical sketches of the most important Parisian scientists of these disciplines from that era, Philippe Pinel, Jean-Étienne Esquirol, Théodule Armand Ribot, Pierre Janet, Henri Louis Charles Piéron, Henry Ey, Jean Delay, Henri Laborit and Henri Hécaen.

In 1817, British physician James Parkinson published a 66-page document entitled "Essay on the Shaking Palsy". This brief text became a classical and fundamental piece in the history of medicine and, in particular, of neurology. The authors of this article wish to pay tribute to this great pioneer of neurology, 200 years after the publication of his findings, which would, in turn, immortalize his name and give rise to the renaming on the entity in 1860 by Professor Jean Martin Charcot, father of neurology. It would be known, henceforth as Parkinson's disease.

Physical management of the Charcot foot.

Crews, Ryan T; Wrobel, James S

2008-01-01

Charcot arthropathy places individuals at risk of developing diabetic foot ulcers and potentially subsequent limb amputation by means of altering the anatomy of the foot and ankle. Physical trauma is an important component to the etiology of the condition. The physical management of the Charcot foot is concerned with minimizing the stress applied to the affected foot and ankle skeletal structure. The most appropriate device is temporally dependent on the progression of the disease. At the initiation of Charcot arthropathy, care by total contact cast is recommended. As the affected bones begin to heal, use of a removable cast walker may be implemented. When the bones reach a fixed state, appropriate footwear is dictated by the degree of deformity.

2013-11-01

Treatment of patients with Charcot midfoot destruction is a difficult and increasingly common clinical problem. The pathoanatomical features of Charcot neuropathy have been evaluated in only a few studies. This study evaluated whether medial navicular subluxation (adduction of the navicular on the talus) is a radiographic finding present in patients with Charcot neuroarthropathy. A retrospective review of 143 consecutive patients diagnosed with Charcot arthropathy of the foot from January 2004 to May 2011 was performed. Patients were identified based on a clinical diagnosis code 713.5 during an outpatient clinic visit with 2 surgeons at a single institution. After exclusion criteria were applied, a series of radiographs of 50 feet in 40 patients were compared with radiographs from an age-matched control group. Radiographic data including talonavicular coverage angle and talonavicular uncoverage percentage were collected. The mean talonavicular coverage angle of the Charcot arthropathy group was 1.5 degrees and of the control group 12.1 degrees (P < .05). The talonavicular uncoverage value for the Charcot arthropathy group was 12.2% and for the control group 22.0% (P < .001). Medial navicular subluxation was a radiographic finding that was more commonly present in patients with Charcot arthropathy than in a matched control group. It is theorized that this finding is attributable to an unopposed pull of the posterior tibial tendon on the destabilized navicular. Level IV, retrospective case series.

The goal of this article is to outline the progression of Charcot's neuroarthropathy. A historical background is detailed, with an emphasis on the current trends in the literature. Acute Charcot's neuroarthropathy requires a prompt diagnosis with the proper practical offloading methods of the affected limb. This, coupled with directed medical and surgical approaches designed to prevent or mitigate deformities, may subsequently reduce the risk of amputation in this high-risk population.

The diabetic Charcot foot syndrome is a serious and potentially limb-threatening lower-extremity complication of diabetes. First described in 1883, this enigmatic condition continues to challenge even the most experienced practitioners. Now considered an inflammatory syndrome, the diabetic Charcot foot is characterized by varying degrees of bone and joint disorganization secondary to underlying neuropathy, trauma, and perturbations of bone metabolism. An international task force of experts was convened by the American Diabetes Association and the American Podiatric Medical Association in January 2011 to summarize available evidence on the pathophysiology, natural history, presentations, and treatment recommendations for this entity.

J.-M. Charcot and simulated neurologic disease: attitudes and diagnostic strategies.

PubMed

Goetz, Christopher G

2007-07-03

Neurologists have long wrestled with the diagnosis of elaborated or feigned disease. Studies have not focused on early techniques utilized to diagnose malingering. To analyze cases of purposeful neurologic malingering among patients treated by the 19th century neurologist J.-M. Charcot, describe his attitudes, and study his methods to separate malingering from primary neurologic diseases. A study was conducted of Charcot's printed and original documents from the Bibliothèque Charcot, Paris, and added documents on American neurology. Charcot recognized that purposeful simulation occurred in isolation as well as in established neurologic disorders. Charcot was strict with subjects motivated by greed or spite, but showed forbearance and wonder in those who created illness as "art for art's sake." Charcot developed diagnostic equipment that measured inspiratory depth and muscle activity as a strategy to identify malingerers. His approach strikingly contrasted with contemporary military medical treatises on malingering and S.W. Mitchell's civilian neurologic approaches that unmasked patients through more aggressive strategies. Charcot provided an academically professional approach to the assessment of neurologic malingering, with a stern, often patronizing attitude, but without categorical condemnation. His diagnostic techniques are echoed by contemporary approaches and emphasized an attention to enhanced and inconsistent patterns of behaviors by malingerers.

Quality of life in children with Charcot-Marie-Tooth disease.

Burns, Joshua; Ryan, Monique M; Ouvrier, Robert A

2010-03-01

The authors studied the health-related quality of life of children aged 5 to 18 years with Charcot-Marie-Tooth disease of varying types and severity and compared it with the general pediatric population. To capture and compare the quality-of-life data across a broad range of ages, the Child Health Questionnaire was completed by parents of 127 children with Charcot-Marie-Tooth disease. Affected children exhibited lower physical, psychological, and social well-being than the general pediatric population, with subsequent worsening of many domains with age. The type of Charcot-Marie-Tooth disease influenced some physical and behavioral quality-of-life domains, while gender, body size, and ethnicity did not. Parent characteristics had generally little impact on the reporting of their child's quality of life, although parents with Charcot-Marie-Tooth disease reported higher bodily pain in their children than those without. Overall, quality of life is negatively affected by the presence and severity of Charcot-Marie-Tooth disease in childhood.

Excess Cost and Healthcare Resources Associated With Delayed Diagnosis of Charcot Foot.

2018-06-21

The purpose of the present study was to demonstrate the effect of a delayed diagnosis of Charcot foot on acute care cost and usage. We used International Classification of Disease, Ninth Revision, Clinical Modification codes, and the California Office for Statewide Health Planning and Development 2009 to 2012 public patient discharge files to identify patients with type 2 diabetes mellitus and Charcot foot. The costs and length of stay were compared for those with a diagnosis of Charcot foot on admission compared with those who received a delayed diagnosis of Charcot foot before discharge. Patient demographic data, diagnoses often mistaken for Charcot foot, and procedures often performed for Charcot foot were assessed to determine the potential effect on costs and length of stay in Charcot foot subjects. A delayed Charcot foot diagnosis was associated with 10.8% greater inpatient costs and 12.1% longer length of stay. These patients required greater resource usage owing to the significantly greater number of procedures performed. A significantly greater number of patients underwent lower extremity amputation when the diagnosis was delayed, resulting in a 30.4% increase in costs and 31.6% longer length of stay. A greater rate of diabetic foot ulcers, foot infections, and osteomyelitis was also observed; however, the cost was only affected by osteomyelitis, and the length of stay was not significantly affected. A delayed diagnosis of Charcot foot at admission resulted in significantly increased acute care costs and longer lengths of stay. Copyright © 2018 The American College of Foot and Ankle Surgeons.

2012-05-01

The peripheral manifestations of the inherited neuropathies are increasingly well characterized, but their effects upon cranial nerve function are not well understood. Hearing loss is recognized in a minority of children with this condition, but has not previously been systemically studied. A clear understanding of the prevalence and degree of auditory difficulties in this population is important as hearing impairment can impact upon speech/language development, social interaction ability and educational progress. The aim of this study was to investigate auditory pathway function, speech perception ability and everyday listening and communication in a group of school-aged children with inherited neuropathies. Twenty-six children with Charcot-Marie-Tooth disease confirmed by genetic testing and physical examination participated. Eighteen had demyelinating neuropathies (Charcot-Marie-Tooth type 1) and eight had the axonal form (Charcot-Marie-Tooth type 2). While each subject had normal or near-normal sound detection, individuals in both disease groups showed electrophysiological evidence of auditory neuropathy with delayed or low amplitude auditory brainstem responses. Auditory perception was also affected, with >60% of subjects with Charcot-Marie-Tooth type 1 and >85% of Charcot-Marie-Tooth type 2 suffering impaired processing of auditory temporal (timing) cues and/or abnormal speech understanding in everyday listening conditions.

Freud with Charcot: Freud's discovery and the question of diagnosis.

PubMed

Lepoutre, Thomas; Villa, François

2015-04-01

Although Charcot's seminal role in influencing Freud is widely stated, although Freud's trip to Paris to study with Charcot is well recognized as pivotal in his shift from neurological to psychopathological work, a key fact of the Freudian heuristic remains largely underestimated: namely, that Freud's psychopathological breakthrough, which gave birth to psychoanalysis, cannot be separated from his 'diagnostic preoccupation', which is a crucial and at times the first organizing principle of his earliest writings. The purpose of this article is therefore to reopen the question of diagnosis by following its development along the path leading from Charcot to Freud. The authors demonstrate that Freud's careful attention to diagnostic distinctions follows strictly in the direction of Charcot's 'nosological method'. More importantly, the article intends to identify the precise way in which his ideas operate in Freud's own work, in order to understand how Freud reinvests them to forge his own nosological system. If the authors trace the destiny of Charcot's lessons as they reach Freud's hands, it is the importance granted to mixed neuroses in Freud's psychopathology that allows them to pinpoint the role played by the diagnostic process in the rationality of psychoanalysis.

The epileptic singers of belle époque Paris.

PubMed

Baxendale, Sallie; Marshall, Fiona

2012-12-01

In late 19th century Paris, people with epilepsy were treated alongside those with hysteria in the now famous Salpêtrière Hospital, where both conditions were deemed to have a neurological basis. When Jean Martin Charcot became chief physician at the Salpêtrière Hospital in 1862, he described himself 'in possession of a kind of museum of living pathology whose holdings were virtually inexhaustible'. He opened the doors of his 'living museum' and exhibited his prize specimens to all of Paris. By putting his patients on display, Charcot introduced a vogue for pathology that permeated well beyond the world of medical enquiry and into the public psyche and vernacular. Not only did Charcot's demonstrations provide the inspiration for high culture in the form of operas, plays and novels, they also provided the inspiration for the 'gommeuses epileptiques' (epileptic singers), who entertained the masses at the café concerts. This paper explores the foundations of our current medical approaches to mental illness and epilepsy, with a particular focus on the boundaries that emerged between hysteria and epilepsy in 19th century Paris. These clinical boundaries were both shaped by and reflected in the popular entertainments in the city.

Metals and magnets in medicine: hysteria, hypnosis and medical culture in fin-de-siècle Paris.

PubMed

Harrington, A

1988-02-01

It is well known that the end of the nineteenth century represented a 'golden age' of hysteria and hypnosis research under Jean-Martin Charcot in Paris, but the extent to which metals and magnets figured in this strange and provocative world has been very incompletely told. This paper offers itself as a first corrective to this neglect. In 1876 a certain elderly physician and mesmerist, Victor Burq, asked the Parisian Société de Biologie formally to establish the validity of his so-called 'metallotherapy' (later 'metalloscopy') treatment for hysteria. The paper argues that Charcot's participation in the investigation of Burq's work--undertaken in conjunction with two other leading French neurologists, Amédée Dumontpallier and Jules Bernard Luys--served as a major catalyst in arousing the great neurologist's interest in hypnosis in the first place, and was subsequently responsible for several of his key beliefs about the underlying physiological link between hypnosis and hysteria. It is also shown how these early metalloscopy studies--and especially the discovery by Charcot and his colleagues of so-called metalloscopic 'transfer'--opened the door to the rise of a neo-mesmeric, and increasingly occult, branch of hypnosis research in French psychiatry, which has to date, in the secondary literature, gone almost wholly unremarked.

High levels of anxiety and depression in diabetic patients with Charcot foot.

Charcot foot is a rare but devastating complication of diabetes. Little research is available on the mental health impact of Charcot foot. Aim of the study is to assess mental health in diabetes patients with Charcot foot and to investigate the moderating effects of socio-demographic factors. The severity of the problem will be statistically evaluated with the help of a reference data set. Cross-sectional questionnaire data using the Hospital Anxiety and Depression Scale (HADS) and demographic background were collected from 50 patients with diabetes and Charcot complications (males 62%; mean age 62.2 ± 8.5 years). Statistical comparisons with a large data set of general diabetes patients acting as a point of reference were carried out. Anxiety and depression levels were high, (anxiety and depression scores 6.4 ± 4 and 6.3 ± 3.6 respectively). Females reported more severe anxiety and depression. Ethnic minorities and patients out of work reported more severe anxiety. Comparisons with published HADS data indicate that diabetes patients with Charcot foot experience more serious levels of anxiety and depression. The high levels of mental health problems which were found in this study in diabetes patients with Charcot foot require recognition by researchers and clinicians. The findings imply the need to screen for mental health problems in diabetes patients with Charcot foot.

Sigmund Freud's evolution from neurology to psychiatry: evidence from his La Salpêtrière library.

PubMed

Bogousslavsky, Julien

2011-10-04

To analyze the parallel between the scientific evolution of Sigmund Freud and his French library during and after his stay with Jean-Martin Charcot at La Salpêtrière in 1885-1886. Systematic review of all identified volumes of Freud's personal library, and comparison with his life data and publications. The largest part of Freud's 125 French medical books up to 1900 (of 3,725 books overall) are devoted to hysteria and hypnotism, published mainly between 1885 and 1895. Over one-third (50) of the neurology (94) and alienism (22) books have Charcot or one of his direct pupils (Janet, Féré, Babinski, Gilles de la Tourette, Richer, Pitres, Sollier, Raymond, Marie, Binet, Ball, Bourneville, Blocq, Berbez, Guinon, and Souques) as author. During that period, Freud evolved from the clinical-anatomic method (after mainly experimental histologic studies) to theoretical neurology (using hysteria and aphasia models) and psychology, a process which subsequently led to the birth of psychoanalysis. The library of Freud gives an interesting account on his own evolving thinking, which led him to leave neurology for psychology and psychoanalysis.

The effectiveness of non-surgical interventions in the treatment of Charcot foot.

PubMed

Smith, Caroline; Kumar, Saravana; Causby, Ryan

2007-12-01

Background  Charcot neuropathic osteoarthropathy is commonly known as 'Charcot foot'. It is a serious foot complication of diabetes mellitus that can frequently lead to foot ulceration, gangrene, hospital admission and foot amputation. A multidisciplinary approach to the management of Charcot foot is taken involving medical and allied health professionals. The management approach may also differ between different countries. To date, there is no systematic review of the literature undertaken to identify the clinical effectiveness of non-operative interventions in the treatment of acute Charcot foot. Objective  The objective of this review was to identify the effectiveness of non-surgical interventions with reducing lesions, ulceration, the rate of surgical intervention, reducing hospital admissions and improve the quality of life of subjects with Charcot foot. Search strategy  A comprehensive search strategy was undertaken on databases available from University of South Australia from their inception to November 2006. Selection criteria  Randomised controlled trials or clinical controlled trials were primarily sought. Critical appraisal of study quality and data extraction was undertaken using Joanna Briggs Institute instruments. Review Manager software was used to calculate comparative statistics. Results  This review identified 11 trials and five trials were included in the review. Three trials involved the use of bisphosphonate, a pharmacological agent. Two experimental treatments were also included, evaluating palliative radiology and magnetic fields. No trials were found using immobilisation and off-loading interventions for acute Charcot foot. The overall methodological quality score of the five studies was moderate. Owing to heterogeneous data, meta-analysis could not be performed. The trials did not report on reducing lesions, ulceration, rate of surgical intervention, hospital admissions and the quality of life of subjects with Charcot foot. The

Data regarding Charcot-Marie-Tooth disease is lacking in Southeast Asian populations. We investigated the frequency of the common genetic mutations in a multiethnic Malaysian cohort. Patients with features of Charcot-Marie-Tooth disease or hereditary liability to pressure palsies were investigated for PMP22 duplication, deletion, and point mutations and GJB1, MPZ, and MFN2 point mutations. Over a period of 3 years, we identified 25 index patients. A genetic diagnosis was reached in 60%. The most common were point mutations in GJB1, accounting for X-linked Charcot-Marie-Tooth disease (24% of the total patient population), followed by PMP22 duplication causing Charcot-Marie-Tooth disease type 1A (20%). We also discovered 2 novel GJB1 mutations, c.521C>T (Proline174Leucine) and c.220G>A (Valine74Methionine). X-linked Charcot-Marie-Tooth disease was found to predominate in our patient cohort. We also found a better phenotype/genotype correlation when applying a more recently recommended genetic approach to Charcot-Marie-Tooth disease. Copyright © 2013 Wiley Periodicals, Inc.

One of the most prevalent neurodegenerative diseases worldwide is still referred to as 'Parkinson's disease'. The condition is named after James Parkinson who, in 1817, described the shaking palsy (paralysis agitans). In the bicentennial year of this publication, we trace when and why the shaking palsy became Parkinson's disease. The term was coined by William Rutherford Sanders of Edinburgh in 1865 and later entered general usage through the influence of Jean-Martin Charcot and the school that he nurtured at the Salpêtrière Hospital in Paris. Despite a move towards more mechanism-based nosology for many medical conditions in recent years, the Parkinson's disease eponym remains in place, celebrating the life and work of this doctor, palaeontologist and political activist.

Post-Newtonian Jeans Analysis

Nazari, Elham; Kazemi, Ali; Roshan, Mahmood

The Jeans analysis is studied in the first post-Newtonian limit. In other words, the relativistic effects on local gravitational instability are considered for systems whose characteristic velocities and corresponding gravitational fields are higher than those permitted in the Newtonian limit. The dispersion relation for the propagation of small perturbations is found in the post-Newtonian approximation using two different techniques. A new Jeans mass is derived and compared to the standard Jeans mass. In this limit, the relativistic effects make the new Jeans mass smaller than the Newtonian Jeans mass. Furthermore, the fractional difference between these two masses increases when themore » temperature/pressure of the system increases. Interestingly, in this limit, pressure can enhance gravitational instability instead of preventing it. Finally, the results are applied to high-temperature astrophysical systems, and the possibility of local fragmentation in some relativistic systems is investigated.« less

Etiology, pathophysiology and classifications of the diabetic Charcot foot

PubMed Central

Papanas, Nikolaos; Maltezos, Efstratios

2013-01-01

In people with diabetes mellitus, the Charcot foot is a specific manifestation of peripheral neuropathy that may involve autonomic neuropathy with high blood flow to the foot, leading to increased bone resorption. It may also involve peripheral somatic polyneuropathy with loss of protective sensation and high risk of unrecognized acute or chronic minor trauma. In both cases, there is excess local inflammatory response to foot injury, resulting in local osteoporosis. In the Charcot foot, the acute and chronic phases have been described. The former is characterized by local erythema, edema, and marked temperature elevation, while pain is not a prominent symptom. In the latter, signs of inflammation gradually recede and deformities may develop, increasing the risk of foot ulceration. The most common anatomical classification describes five patterns, according to the localization of bone and joint pathology. This review article aims to provide a brief overview of the diabetic Charcot foot in terms of etiology, pathophysiology, and classification. PMID:23705058

Ankle fusion is difficult to achieve in the diabetic Charcot ankle Brodsky type 3a because of the poor quality of the bone and the inability to achieve a stable biomechanical construct. The aim of this study was to report the outcome of ankle fusion using a combination of an intramedullary nail and a circular external fixator in patients with diabetic Charcot arthropathy. We prospectively studied 24 patients with diabetic Charcot arthropathy of the ankle who were treated by fusion of the tibiotalar joint using a combined retrograde intramedullary nail and Ilizarov external fixator. Their mean age was 50.7 ± 6.9 (range, 43-62) years. The mean follow-up after surgery was 36.4 ± 5.8 (range, 24-98) months. Twenty-two patients (92%) achieved clinical and radiographic solid bony fusion. No patients in this series needed amputation. All the patients were pain free, and the mean American Orthopaedic Foot & Ankle Society Score (AOFAS) improved significantly from 34.6 ± 6.8 to 66.4 ± 4.5 at the last follow-up. Two patients developed an ulcer over the heel due to a prominent nail. The ulcer healed after nail removal. Eight patients developed pin tract infection. We report a successful outcomes of ankle fusions using combined intramedullary nail locked only proximally and ring external fixator (hybrid fixation) in patients with diabetic Charcot arthropathy.

History of physical and 'moral' treatment of hysteria.

2014-01-01

This historical review presents the advances made mostly during the last 200 years on the description, concepts, theories, and (more specifically) cure of patients suffering from hysteria, a still obscure entity. The denomination of the syndrome has changed over time, from hysteria (reinvestigated by Paul Briquet and Jean-Martin Charcot) to pithiatism (Joseph Babinski), then to conversion neurosis (Sigmund Freud), and today functional neurological disorders according to the 2013 American Neurological Association DSM-5 classification. The treatment was renewed in the second half of the 19th century in Paris by Paul Briquet and then by Jean-Martin Charcot. Hysterical women, who represented the great majority of cases, were cured by physical therapy (notably physio-, hydro-, and electrotherapy, and in some cases ovary compression) and 'moral' therapies (general, causal therapy, rest, isolation, hypnosis, and suggestion). At the turn of the 19th and 20th centuries, psychotherapy, psychoanalysis, and persuasion were established respectively by Pierre Janet, Sigmund Freud, and Joseph Babinski. During World War I, military forces faced a large number of posttrauma neurosis cases among soldiers (named the 'Babinski-Froment war neurosis' and Myers 'shell shock', in the French and English literature, respectively). This led to the use of more brutal therapies in military hospitals, combining electrical shock and persuasion, particularly in France with Clovis Vincent and Gustave Roussy, but also in Great Britain and Germany. After World War I, this method was abandoned and there was a marked decrease in interest in hysteria for a long period of time. Today, the current treatment comprises (if possible intensive) physiotherapy, together with psychotherapy, and in some cases psychoanalysis. Antidepressants and anxiolytics may be required, and more recently cognitive and behavioral therapy. Repetitive transcranial magnetic stimulation is a new technique under investigation which

The Scientific Illusion of Victor Burq (1822-1884).

PubMed

Walusinski, Olivier

2018-03-07

Victor Burq (1822-1884) is closely associated with a therapy named "burquism" by Jean-Martin Charcot, which was used in treating hysteria, especially hysteric anesthesia and paralysis, by applying metals, mainly copper, to affected zones. In 1876, Charcot, Luys, and Dumontpallier, commissioned by the Société de Biologie, issued 2 opinions validating the results obtained by Burq during the 25 years he dedicated to his research. From that point forward, the careers of these 3 famous physicians were lastingly reoriented toward the practice of hypnosis. This neo-mesmeric resurgence at the end of the nineteenth century can be considered the cause of an epistemological change that gave rise to "psychological medicine." During the repeated cholera epidemics in the mid-nineteenth century, Burq recommended preventive and corrective ingestion of copper, after observing that smelter workers were unaffected by the disease. The mechanisms of copper's anti-bacterial action have since been elucidated and legitimize Burq's anti-cholera campaign. Burq also advocated the ingestion of copper sulphate to treat diabetes. Current-day findings on intestinal microbiota and how these organisms influence blood sugar regulation support Burq's claims, considered far-fetched for many years. © 2018 S. Karger AG, Basel.

[A nosology for supernatural phenomena and the construction of the 'possessed' brain in the nineteenth century].

PubMed

Goncalves, Valeria Portugal; Ortega, Francisco

2013-06-01

At the end of the twentieth century, supernatural phenomena such as so called trances and possession by spirits received a scientific classification, which includes the numerous diagnoses of the dominant psychiatry. At the end of the nineteenth century we can observe a process of scientific categorization of phenomena considered to have originated in superstition or popular imagination. In this work we show how trances and spiritual possession were studied by Franz Anton Mesmer and his followers when developing the concept of magnetism; by James Braid during the creation of his theory of hypnosis; and by Jean Martin Charcot, which marked the entry of hysteria into nosological classification.

Combined Internal and External Fixation for Diabetic Charcot Reconstruction: A Retrospective Case Series.

PubMed

Hegewald, Kenneth W; Wilder, Megan L; Chappell, Todd M; Hutchinson, Byron L

2016-01-01

Diabetic Charcot neuroarthropathy is a complex, limb-threatening disease process with major lifestyle-altering repercussions for patients. When Charcot neuroarthropathy leads to unstable deformity, ulceration, and potential infection despite conservative therapies, foot and ankle surgeons often consider reconstructive limb salvage procedures to restore function. The purpose of the present study was to evaluate the clinical and radiographic outcomes of diabetic Charcot reconstruction using combined internal and external fixation. A total of 22 patients were reviewed; 16 (72.73%) midfoot and 6 (27.27%) tibiotalocalcaneal arthrodesis procedures were consecutively performed from March 2009 to May 2013. All surgical procedures were performed in nonacute phases of the Charcot process in patients with diagnosed diabetes mellitus and documented peripheral neuropathy. Patients were excluded from the study if they were not diabetic despite having undergone Charcot reconstruction, regardless of the fixation method, or if they did not complete radiographic imaging. During a mean follow-up period of 58.60 ± 42.37 (range 16 to 164) weeks, limb salvage was achieved in 20 patients (90.91%), and 2 (9.09%) required below-the-knee amputation at a mean of 42 ± 14.14 weeks. Wound dehiscence occurred in 8 (36.36%), pin tract infection in 10 (45.45%), and superficial wound infection in 9 (40.91%) and peaked in bimodal fashion at 4 and 8 weeks postoperatively. Radiographic analysis of the pre- versus postoperative alignment showed statistically significant changes in the lateral talo-first metatarsal angle (p = .02) and lateral talar declination angle (p = .01). The limb salvage rates with diabetic Charcot reconstruction are improving in part because of the continued development of increasingly superior modalities for both internal and external fixation.

The aim of this study was to investigate atherosclerotic load at the lower extremity in patients with diabetic foot and charcot neuro-arthropathy and compare them with patients with diabetic foot without charcot neuro-arthropathy. This retrospective study consists of 78 patients with diabetic foot who had lower extremity angiography with antegrade approach. All patients were classified into two groups; neuro ischemic wounds with charcot neuro-arthropathy (30/78) and without charcot neuro-arthropathy (48/78).Atherosclerotic load at the side of diabetic foot was determined by using the Bollinger angiogram scoring method. Comparison of atherosclerotic load between the two groups was performed. The mean of total and infrapopliteal level angiogram scoring of all patients was 33.3 (standard deviation, sd:±17.2) and 29.3 (sd:±15.6), respectively. The mean of total and infrapopliteal level angiogram scoring of neuroischemic wounds with charcot neuro-arthropathy group was 18.1 (sd:±11.6) and 15.7 (sd:±10.4), respectively. The mean of total and infrapopliteal level angiogram scoring of neuroischemic wounds without charcot neuro-arthropathy group was 42.8 (sd:±12.7) and 37.7 (sd:±12.0), respectively. There was a statistically significant difference between the two groups of mean total and infrapopliteal angiogram scoring (p < 0.01). This angiographic study confirms that the atherosclerotic load in patients with diabetic foot and chronic charcot neuro-arthropathy is significantly less than in patients with neuroischemic diabetic foot wounds without chronic charcot neuro-arthropathy.

Florence Nightingale in absentia: nursing and the 1893 Columbian Exposition.

PubMed

Selanders, Louise C; Crane, Patrick

2010-12-01

In 1893, Chicago hosted the Columbian Exposition. This event showcased America's social, cultural, and scientific advances and its growing cultural parity with Western Europe. This was the first major exposition in which women played a prominent role. Integral to the fair was a series of Congresses that provided an international platform for discussion of social issues. The Congress on Hospitals, Dispensaries, and Nursing, a section of the International Congress of Charities, Correction, and Philanthropy, particularly focused on health care issues. Nursing leaders from Europe and North America participated. Although Florence Nightingale provided a major paper that was read at the Congress, she was unable to attend the event. The intent of this article is to examine the issues and themes debated at the 1893 Congress and identify how the influence of Nightingale effected these discussions and the development of Western nursing for the next half-century.

Circular External Fixation as a Primary or Adjunctive Therapy for the Podoplastic Approach of the Diabetic Charcot Foot.

Short, Daniel J; Zgonis, Thomas

2017-01-01

Numerous techniques have been described for surgical management of the diabetic Charcot foot. External fixation has become a main surgical tool for the reconstructive foot and ankle surgeon when dealing with the ulcerated diabetic Charcot foot. In the presence of an open wound and/or osteomyelitis, staged reconstruction with circular external fixation becomes ideal for salvage of the diabetic lower extremity. Also, circular external fixation can provide simultaneous compression and stabilization, correct the underlying osseous or soft tissue deformities, and surgically offload the diabetic Charcot foot. This article describes a variety of circular external fixation applications for the diabetic Charcot foot. Copyright © 2016 Elsevier Inc. All rights reserved.

The origins of scientific cinematography and early medical applications.

PubMed

Barboi, Alexandru C; Goetz, Christopher G; Musetoiu, Radu

2004-06-08

To examine the neurologic cinematographic contributions of Gheorghe Marinescu. Near the end of the 19th century, cinematography developed and was immediately recognized as a new technique applicable to medical documentation. After studying with several prominent European neurologists and deeply influenced by Jean-Martin Charcot, Marinescu returned to Bucharest in 1897 and applied moving picture techniques to the study of neurologic patients. The Romanian State Archives were researched for original Marinescu films, and related publications were translated from Romanian and French. Between 1899 and 1902, Marinescu perfected the use of cinematography as a research method in neurosciences and published five articles based on cinematographic documents. He focused his studies particularly on organic gait disorders, locomotor ataxia, and hysteria. He adapted Charcot's method of lining up several patients with the same disorder and showing them together to permit appreciation of archetypes and formes frustes. He decomposed the moving pictures into sequential tracings for publication. He documented treatment results with cases filmed before and after therapy. Processed and digitized excerpts of these films accompany this manuscript. Marinescu's cinematographic studies led to several original contributions in clinical neurology. Remaining film archives include examples of many neurologic diseases, his examination techniques, and the working medical environment of the young founder of the Romanian school of neurology.

[Neurology of hysteria (conversion disorder)].

PubMed

Sonoo, Masahiro

2014-07-01

Hysteria has served as an important driving force in the development of both neurology and psychiatry. Jean Martin Charcot's devotion to mesmerism for treating hysterical patients evoked the invention of psychoanalysis by Sigmund Freud. Meanwhile, Joseph Babinski took over the challenge to discriminate between organic and hysterical patients from Charcot and found Babinski's sign, the greatest milestone in modern neurological symptomatology. Nowadays, the usage of the term hysteria is avoided. However, new terms and new classifications are complicated and inconsistent between the two representative taxonomies, the DSM-IV and ICD-10. In the ICD-10, even the alternative term conversion disorder, which was becoming familiar to neurologists, has also disappeared as a group name. The diagnosis of hysteria remains important in clinical neurology. Extensive exclusive diagnoses and over investigation, including various imaging studies, should be avoided because they may prolong the disease course and fix their symptoms. Psychological reasons that seem to explain the conversion are not considered reliable. Positive neurological signs suggesting nonorganic etiologies are the most reliable measures for diagnosing hysteria, as Babinski first argued. Hysterical paresis has several characteristics, such as giving-way weakness or peculiar distributions of weakness. Signs to uncover nonorganic paresis utilizing synergy include Hoover's test and the Sonoo abductor test.

Sanders, Lee J

2008-01-01

Regrettably, physicians today receive very little instruction in the history of medicine. Most health care providers have a very limited, contemporary knowledge of the condition that we know of as the Charcot foot. Yet, historical concepts of the pathogenesis and natural history of this condition provide us with important lessons that enhance our understanding, recognition, and management of this rare but debilitating neurogenic arthropathy. It is my belief that knowledge of the history of medicine provides us with a better understanding of present-day issues and clearer vision as we look to the future. This article describes some of the important lessons learned from the history of the Charcot foot.

Gheorghe Marinescu (Georges Marinesco, in French) is a Romanian physician, founder of the School of Neurology in that country. He begins his medical studies in Bucharest, then has the opportunity to reach Paris and join the School of Neurology in La Salpêtrière Hospital, lead by Jean-Martin Charcot. This trip will forever imprint the mind of Marinescu, a great friend of France, a respectful student of Charcot and a friendly colleague of many Parisian neurologists. Marinescu's works are multiple and very important. He describes the succulent hand in syringomyelia and the palmar-jaw reflex. Marinescu is also one of the first to use the cinema for medical purposes. His work as an anatomo-clinician, a method developed by Charcot, is important. We denote the description of the locus niger affected by tuberculosis in a case of parkinsonism (this description paving Etienne Brissaud's way to highlight the anatomical origin of Parkinson's disease), the original clinical description of Marinesco-Sjögren syndrome, and that of medullomyoblastoma. Marinescu is also a famous neurocytologist as evidenced by his work, La Cellule Nerveuse, published in 1909. The first volume of the book is devoted to the aspects of the normal nervous tissue: the neurofibrillar network, the chromatophilic elements, and the paranucleolar corpuscles (now known as Marinescu's bodies). The second volume of the book is almost related to features revealed by experimental lesions: chromatolysis and neuronophagia. Furthermore, Marinescu describes with Oscar Blocq, small nodules than are now regarded as the first description of senile plaques.

Surgical versus accommodative treatment for Charcot arthropathy of the midfoot.

PubMed

Pinzur, Michael

2004-08-01

The treatment of Charcot foot arthropathy is one of the most controversial issues facing orthopaedic foot and ankle surgeons. Although current orthopaedic textbooks are in almost universal agreement that treatment should be nonoperative, accommodating the deformity with orthotic methods, most peer-reviewed clinical studies recommend early surgical correction of the deformity. In a university health system orthopaedic foot and ankle clinic with a special interest in diabetic foot disorders, a moderate approach evolved for management of this difficult patient population. Patients with Charcot arthropathy and plantigrade feet were treated with accommodative orthotic methods. Those with nonplantigrade feet were treated with surgical correction of the deformity, followed by long-term management with commercial therapeutic footwear. The desired outcome for both groups was long-term management with standard, commercially available, therapeutic depth-inlay shoes and custom-fabricated accommodative foot orthoses. During a 6-year period, 198 patients (201 feet) were treated for diabetes-associated Charcot foot arthropathy. The location of the deformity was in the midfoot in 147 feet, in the ankle in 50, and in the forefoot in four. At a minimum 1-year follow-up, 87 of the 147 feet with midfoot disease (59.2%) achieved the desired endpoint without surgical intervention. Sixty (40.8%) required surgery. Corrective osteotomy with or without arthrodesis was attempted in 42, while debridement or simple exostectomy was attempted in 18 feet. Three patients had initial amputation (one partial foot amputation, one Syme ankle disarticulation, and one transtibial amputation), and five had amputation (two Syme ankle disarticulations and three transtibial amputations) after attempted salvage failed. Using a simple treatment protocol with the desired endpoint being long-term management with commercially available, therapeutic footwear and custom foot orthoses, more than half of patients

Illness as the saturated phenomenon: the contribution of Jean-Luc Marion.

PubMed

Grīnfelde, Māra

2018-05-24

During the last few decades, many thinkers have advocated for the importance of the phenomenological approach in developing the understanding of the lived experience of illness. In their attempts, they have referred to ideas found in the history of phenomenology, most notably, in the works of Edmund Husserl, Martin Heidegger, Maurice Merleau-Ponty and Jean-Paul Sartre. The aim of this paper is to sketch out an interpretation of illness based on a yet unexplored conceptual framework of the phenomenology of French thinker Jean-Luc Marion. Focusing on concepts of the saturated phenomenon and flesh, the paper develops an interpretation of illness as the saturated phenomenon, which highlights a variety of dimensions of illness already elaborated within the phenomenology of medicine, such as the affective dimension of illness, the disruptive dimension of illness, the transformed perception of the self in illness, mineness of flesh in illness and the inexpressible and hermeneutical dimension of illness. In addition to that, the paper explores some of the consequences the proposed interpretation of illness offers regarding the nature of illness and health. It is argued that illness in its essence is very similar to the experience of other saturated phenomena, suggesting that the difference between them does not lie within the character of the affective givenness, but rather within the dynamic relationship between the affective givenness and its conceptualization. It is also shown that the experience of health is compatible with the experience of saturation and thus is not limited to the tacit and harmonious background state.

Charcot-Marie-Tooth disease is a group of hereditary peripheral neuropathies that share clinical characteristics of progressive distal muscle weakness and atrophy, foot deformities, distal sensory loss, as well as diminished tendon reflexes. Hundreds of causative DNA changes have been found, but much of the genetic basis of the disease is still unexplained. Mutations in the ALS5/SPG11/KIAA1840 gene are a frequent cause of autosomal recessive hereditary spastic paraplegia with thin corpus callosum and peripheral axonal neuropathy, and account for ∼ 40% of autosomal recessive juvenile amyotrophic lateral sclerosis. The overlap of axonal Charcot-Marie-Tooth disease with both diseases, as well as the common autosomal recessive inheritance pattern of thin corpus callosum and axonal Charcot-Marie-Tooth disease in three related patients, prompted us to analyse the ALS5/SPG11/KIAA1840 gene in affected individuals with autosomal recessive axonal Charcot-Marie-Tooth disease. We investigated 28 unrelated families with autosomal recessive axonal Charcot-Marie-Tooth disease defined by clinical, electrophysiological, as well as pathological evaluation. Besides, we screened for all the known genes related to axonal autosomal recessive Charcot-Marie-Tooth disease (CMT2A2/HMSN2A2/MFN2, CMT2B1/LMNA, CMT2B2/MED25, CMT2B5/NEFL, ARCMT2F/dHMN2B/HSPB1, CMT2K/GDAP1, CMT2P/LRSAM1, CMT2R/TRIM2, CMT2S/IGHMBP2, CMT2T/HSJ1, CMTRID/COX6A1, ARAN-NM/HINT and GAN/GAN), for the genes related to autosomal recessive hereditary spastic paraplegia with thin corpus callosum and axonal peripheral neuropathy (SPG7/PGN, SPG15/ZFYVE26, SPG21/ACP33, SPG35/FA2H, SPG46/GBA2, SPG55/C12orf65 and SPG56/CYP2U1), as well as for the causative gene of peripheral neuropathy with or without agenesis of the corpus callosum (SLC12A6). Mitochondrial disorders related to Charcot-Marie-Tooth disease type 2 were also excluded by sequencing POLG and TYMP genes. An additional locus for autosomal recessive Charcot

Serial casting for reconstruction of a deformed Charcot foot: a case report.

PubMed

Rosenblum, Jonathan I; Weiss, Shmuel; Gazes, Michael; Amit-Kohn, Michal

2015-05-01

Charcot neuroarthropathy may occur in patients with peripheral neuropathy who do not notice pain while their bones and joints collapse or breakdown under the constant pressure of body weight. This can lead to ulcerations from severe deformity and potentially limb-threatening and life-threatening infections. Current treatments vary from immobilization to extensive reconstructive surgical interventions. Serial casting, used to correct many pediatric deformities while bones are often more pliable, was used with a 63-year-old male patient who presented with an active phase of Charcot foot with ulceration. The patient previously underwent foot reconstruction and had all hardware removed prior to serial casting. Due to the potential pliability of the bones, serial casting was attempted to reform the shape and position of the foot in a reverse Ponseti-type serial casting to create a more stable structure with less deformity that could lead to epithelial breakdown. The patient regained full ambulation with a plantargrade foot and no wounds, and was followed without complications for 36 months. Serial weekly casting was an effective modality for treatment of this patient's Charcot foot deformity.

The microbiologist Jean Comandon is famous for his studies on the movement of the syphilis bacteria as differentiated in various forms by ultramicroscope. He was also a pioneer on the technical application of the microcinematography in laboratory research. His collaboration with clinicians and surgeons in the study of various pathological disorders is little known. From 1918 to the 1920s, he collaborated with such neurologists as André Thomas, Jean Athanase Sicard, and others in the study of various neurological disorders by using cinematography as a scientific tool for understanding the clinical and pathological mechanisms of diseases. These collaborations allowed him to be involved in the beginnings of the French cinematography industry, especially with Charles Pathé who established a small film studio laboratory in Vincennes where a multidisciplinary group improved the application of cinematography in clinical medical practice.

In re Martin.

PubMed

1993-07-19

The Appellate Court of Michigan established a hierarchical process to determine whether to withhold or withdraw life-sustaining medical treatments from patients who are no longer competent. The court held that terminal illness is only one of the factors to be considered. Only when a patient is shown to lack the requisite capacity to make treatment decisions may clear and convincing evidence of that patient's prior written or oral expression of preference be considered. In the absence of such clear and convincing evidence, substituted judgment or surrogate consent based on trustworthy evidence of the patient's wishes may be employed. If neither standard can be met, only then may the best interests of the patient be considered as a last resort. The court also noted that family members as well as guardians or conservators are appropriate participants in the determination of the medical treatment of such patients. In the case under appeal, there was conflicting testimony about Mr. Martin's earlier verbal statements concerning treatment preferences under various conditions. Also expert medical testimony was in disagreement about the degree of Martin's social interactions, comprehension, and competence. Finally, the case had been brought to the trial court by Martin's mother and sister who sought to remove Martin's wife as legal guardian because they disagreed with her intention to have Martin's artificial nutrition and hydration withdrawn. The appellate court remanded the case to the trial court to consider Martin's capacity to make the decision and, if he were deemed incompetent, to determine whether without clear and convincing evidence of his preferences the decision to withdraw treatment could be exercised by a surrogate decision maker.

The History of Parkinson's Disease: Early Clinical Descriptions and Neurological Therapies

PubMed Central

Goetz, Christopher G.

2011-01-01

Although components of possible Parkinson's disease can be found in very early documents, the first clear medical description was written in 1817 by James Parkinson. In the mid-1800s, Jean-Martin Charcot was particularly influential in refining and expanding this early description and in disseminating information internationally about Parkinson's disease. He separated Parkinson's disease from multiple sclerosis and other disorders characterized by tremor, and he recognized cases that later would likely be classified among the Parkinsonism-plus syndromes. Early treatments of Parkinson's disease were based on empirical observation, and anticholinergic drugs were used as early as the nineteenth century. The discovery of dopaminergic deficits in Parkinson's disease and the synthetic pathway of dopamine led to the first human trials of levodopa. Further historically important anatomical, biochemical, and physiological studies identified additional pharmacological and neurosurgical targets for Parkinson's disease and allow modern clinicians to offer an array of therapies aimed at improving function in this still incurable disease.

Neurological caricatures since the 15th century.

During the Renaissance, different artists began to draw medical illustrations from various viewpoints. Leonardo da Vinci was among those who sought to portray the emotional as well as the physical qualities of man. Other European artists described caricatural aspects of medical activities. In Northern Europe, Albrecht Durer, Hieronymus Bosch, and Pieter Brueghel were also famous for drawing caricatures. Later English artists, notably William Hogarth, Thomas Rowlandson, James Gillray, and the Cruikshanks, satirized life in general and the medical profession in particular. In Spain, Francisco Goya's works became increasingly macabre and satirical following his own mysterious illness and, in France, Honore Daumier used satire and humor to expose medical quackery. Also physicians such as Charles Bell and Jean-Martin Charcot were talented caricaturists. Their own personal artistic styles reflected their approach and gave a different "image" of neurology. Caricatures were popular portraits of developments in science and medicine and were frequently used whenever scientific language was too difficult to disseminate, in particular in the field of neurology.

Trichloroethylene (TCE), commonly used as an industrial solvent, is ubiquitous in our living environment. TCE exposure can induce hepatocellular carcinoma (HCC) in mice, but the underlying mechanisms remain elusive. To understand the role of miRNA in the hepatocarcinogenesis of TCE, we examined the miRNA expression profiles by microarray in the liver of B6C3F1 male mice exposed to TCE at 0 or 1000 mg/kg b.w. Nine differentially expressed miRNAs were identified, out of which miR-182-5p exhibited the highest increase in expression. Moreover, the TCE-induced upregulation of miR182-5p in mouse liver was dose dependent and correlated with promoter DNA hypomethylation. Treatment of mouse liver cell lines (BNL CL.2 and Hepa1-6) with TCE at non-toxic doses (0.1 and/or 0.3 mM) significantly increased the expression level of miR-182-5p accompanied with elevated cell proliferation. The TCE-induced cell proliferation was further found to be mediated by miR-182-5p overexpression. Additionally, tumor suppressor gene Cited2, which was downregulated in TCE exposed mouse liver cells, was proved to be a direct target of miR-182-5p. In conclusion, TCE might up-regulate miR-182-5p expression by DNA hypomethylation, which could suppress Cited2 and improve cell proliferation rate, resulting in liver tumor. © The Author 2016.

Charcot foot is a severe complication to diabetes mellitus, associated with diabetic neuropathy. Any long-term effects of a Charcot foot on the progress of neuropathy are still largely unexplored. The objective was to investigate whether a previous Charcot foot had any long-term effects on the progress of neuropathy. An 8.5-year follow-up case-control study of 49 individuals with diabetes mellitus, 24 of whom also had Charcot foot at baseline visit in 2005-2007. Neuropathy was assessed with a questionnaire, biothesiometry, heart rate variability and venous occlusion plethysmography. Of the 49 baseline participants, 22 were able to participate in the follow-up. Twelve had passed away in the meantime. Heart rate variability was unchanged in both groups; from 9.7 to 7.2 beats/min (p = 0.053) in the Charcot group, and 14.3 to 12.6 beats/min (p = 0.762) in the control group. Somato-sensoric neuropathy showed no difference between baseline and follow-up in the Charcot group (from 39.1 to 38.5 V) (p = 0.946), but a significantly worsened sensitivity in the control group (from 25.1 to 38.9 V) (p = 0.002). In conclusion, we found that any differences in somatic or cardial autonomic neuropathy present at baseline had disappeared at follow-up after 8.5 years.

See Scherer (doi:10.1093/awv279) for a scientific commentary on this article.Charcot-Marie-Tooth type 1 neuropathies are inherited disorders of the peripheral nervous system caused by mutations in Schwann cell-related genes. Typically, no causative cure is presently available. Previous preclinical data of our group highlight the low grade, secondary inflammation common to distinct Charcot-Marie-Tooth type 1 neuropathies as a disease amplifier. In the current study, we have tested one of several available clinical agents targeting macrophages through its inhibition of the colony stimulating factor 1 receptor (CSF1R). We here show that in two distinct mouse models of Charcot-Marie-Tooth type 1 neuropathies, the systemic short- and long-term inhibition of CSF1R by oral administration leads to a robust decline in nerve macrophage numbers by ∼70% and substantial reduction of the typical histopathological and functional alterations. Interestingly, in a model for the dominant X-linked form of Charcot-Marie-Tooth type 1 neuropathy, the second most common form of the inherited neuropathies, macrophage ablation favours maintenance of axonal integrity and axonal resprouting, leading to preserved muscle innervation, increased muscle action potential amplitudes and muscle strengths in the range of wild-type mice. In another model mimicking a mild, demyelination-related Charcot-Marie-Tooth type 1 neuropathy caused by reduced P0 (MPZ) gene dosage, macrophage blockade causes an improved preservation of myelin, increased muscle action potential amplitudes, improved nerve conduction velocities and ameliorated muscle strength. These observations suggest that disease-amplifying macrophages can produce multiple adverse effects in the affected nerves which likely funnel down to common clinical features. Surprisingly, treatment of mouse models mimicking Charcot-Marie-Tooth type 1A neuropathy also caused macrophage blockade, but did not result in neuropathic or clinical improvements

Charcot foot is a rare but severe complication to diabetes and peripheral neuropathy. It is still unclear if an acute Charcot foot has long-term effects on the bone metabolism. To investigate this, we conducted a follow-up study to examine if a previously acute Charcot foot has any long-term effects on bone mineral density (BMD) or local or systemic bone metabolism. An 8.5-year follow-up case-control study of 44 individuals with diabetes mellitus, 24 of whom also had acute or chronic Charcot foot at the baseline visit in 2005-2007, who were followed up in 2015 with DXA scans and blood samples. 21 of the 44 baseline participants participated in the follow-up. There were no difference in the change in total hip BMD from baseline to follow-up in either the Charcot or the control group (p = 0.402 and 0.517), and no increased risk of osteoporosis in the previous Charcot feet either. From baseline to follow-up, there was a significant difference in the change in levels of fsRANK-L in the Charcot group, but not in the control group (p = 0.002 and 0.232, respectively). At follow-up, there were no differences in fsRANK-L between the groups. The fsRANK-L/OPG ratio also significantly decreased from baseline to follow-up in the Charcot group (3.4 versus 0.5) (p = 0.009), but not in the control group (1.3 versus 1.1) (p = 0.302). We found that diabetes patients with an acute Charcot foot have an elevated fsRANK-L/OPG ratio, and that the level decreased from baseline to follow-up to be comparable to the level in diabetes patients without previous or current Charcot foot. We found no permanent effect of an acute Charcot foot on hip or foot BMD. Copyright © 2017 Elsevier Inc. All rights reserved.

We hypothesized that newly formed osteoclasts from patients with acute Charcot osteoarthropathy can resorb surfaces of bone more extensively compared with controls. Peripheral blood monocytes, isolated from eight Charcot patients and nine controls, were cultured in vitro on 24-well plates and bovine bone discs in duplicate with macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor κβ ligand (RANKL). Osteoclast formation was assessed by tartrate-resistant acid phosphatase staining (TRAcP) at day 17. Resorption was measured at day 21 after toluidine blue staining by two methods: (1) area of resorption at the surface by image analysis (%) and (2) area of resorption under the surface (μm(2)) measured by a Dektak 150 Surface Profiler. Ten 1,000 μm-long scans were performed per disc. Pits were classified as unidented, bidented, and multidented according to their shape. Although the number of newly formed TRAcP positive multinucleated cells (>3 nuclei) was similar in M-CSF + RANKL-treated cultures between controls and Charcot patients, the latter exhibited increased resorbing activity. The area of resorption on the surface by image analysis was significantly greater in Charcot patients compared with controls (21.1 % [14.5-26.2] vs. 40.8 % [35.4-46.0], median [25-75th percentile], p < 0.01), as was the area of resorption under the surface (2.7 x 10(3) μm(2) [1.6 x 10(3)- 3.9 x 10(3)] vs. 8.3 x 10(3) μm (2) [5.6 x 10(3)- 10.6 x 10(3), [corrected] p < 0.01) after profilometry. In Charcot patients pits were deeper and wider and more frequently presented as multidented pits. This application of the Dektak 150 Surface Profiler revealed novel differences in resorption pit profile from osteoclasts derived from Charcot patients compared with controls. Resorption in Charcot patients was mediated by highly aggressive newly formed osteoclasts from monocytes eroding large and deep areas of bone.

The negative impact on health-related quality of life in patients with Charcot foot has prompted operative correction of the acquired deformity. Comparative effectiveness financial models are being introduced to provide valuable information to assist clinical decision making. Seventy-six patients with Charcot foot underwent operative correction with the use of circular external fixation. Thirty-eight (50%) had osteomyelitis. A control group was created from 17 diabetic patients who successfully underwent transtibial amputation and prosthetic fitting during the same period. Cost of care during the 12 months following surgery was derived from inpatient hospitalization, placement in a rehabilitation unit or skilled nursing facility, home health care including parenteral antibiotic therapy, physical therapy, and purchase of prosthetic devices or footwear. Fifty-three of the patients with limb salvage (69.7%) did not require inpatient rehabilitation. Their average cost of care was $56,712. Fourteen of the patients with amputation (82.4%) required inpatient rehabilitation, with an average cost of $49,251. Many surgeons now favor operative correction of Charcot foot deformity. This investigation provides preliminary data on the relative cost of transtibial amputation and prosthetic limb fitting compared with limb salvage. The use of comparative effectiveness models such as this simple attempt may provide valuable information in planning resource allocation for similar complex groups of patients.

To study the applicability and responsiveness of the motor function measure (total score and sub-scores D1, D2 and D3) in patients with Charcot-Marie-Tooth disease. Two hundred and thirty-three patients aged 4-86 years were included in the descriptive study. Scores and sub-scores were analyzed by age and by disease subtypes. Sensitivity to change (responsiveness) was estimated in patients having had at least two evaluations with at least six months between the first and the second. Motor function measure scores decrease with age, especially sub-scores D1 and D3. There were no significant differences between the scores according to type of Charcot-Marie-Tooth disease. The scores were significantly higher for ambulatory than for non-ambulatory patients. Significant responsiveness was demonstrated only in type 2 Charcot-Marie-Tooth disease. Our results suggest that, especially for D1 and D3 sub-scores, the motor function measure is a reliable and valid outcome measure that can be usefully applied in longitudinal follow-up. Studies of longer duration could demonstrate its responsiveness in other Charcot-Marie-Tooth disease subtypes. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

[Hindfoot fusion for Charcot osteoarthropathy with a curved retrograde nail].

2015-01-01

Charcot osteoarthropathy of the hindfoot with considerable dislocation and instability represents a therapeutic dilemma. The treatment goal is a plantigrade, stable foot that is free of infection and ulceration with the ability to ambulate in special footwear. Over a period of 6 years, we performed 23 hindfoot fusions in 21 patients with manifest Charcot arthropathy with the help of a curved retrograde nail (HAN). All patients suffered from insulin-dependent diabetes mellitus with polyneuropathy; 12 patients had additional peripheral vasculopathy. An average of 3.5 previous surgeries had been performed prior to hindfoot fusion. Complete tibiotalocalcaneal fusion was obtained in 16 of 21 patients (76 %). Of these 21 patients, 18 (86 %) were followed clinically and radiologically for an average of 2 years. Overall, 16 patients (89 %) reported a substantial subjective improvement compared to the preoperative state. Hardware failure occurred in 7 cases (30 %) that could be brought to consolidation with exchange of the locking bolts or the complete nail. In 5 cases (22 %), a postoperative hematoma had to be removed and in 8 cases (35 %) wound edge necrosis was treated with local wound care. In 2 cases (9 %), a secondary or reactivated osteitis occurred that finally required below knee amputation. Tibiotalocalcaneal fusion with a curved retrograde intramedullary nail (HAN) is an effective treatment option in highly unstable and deforming Charcot osteoarthropathy of the hindfoot. It is an alternative to external or other internal fixation methods and helps to avoid below knee amputation in more than 90 % of cases.

Charcot-Marie-Tooth (CMT) disease, a hereditary motor and sensory neuropathy that comprises a complex group of more than 50 diseases, is the most common inherited neuropathy. CMT is generally divided into demyelinating forms, axonal forms and intermediate forms. CMT is also characterized by a wide genetic heterogeneity with 29 genes and more than 30 loci involved. The most common pattern of inheritance is autosomal dominant (AD), although autosomal recessive (AR) forms are more frequent in Mediterranean countries. In this chapter we give an overview of the associated genes, mechanisms and epidemiology of AR-CMT forms and their associated phenotypes.

The REE and U, Th, Zr, Hf, Sc have been analyzed in samples from Atlantis II and Shaban/Jean Charcot Deeps in the Red Sea. The high Zr/Hf ratio in some sediments indicates the presence of fish debris or of finely crystallized apatite. The positive ..sigma..REE vs P/sub 2/O/sub 5/ and ..sigma..REE vs Zr/Hf correlations show that fish debris and finely crystallized apatite are the main REE sink in Atlantis II Deep sediments as in other marine environments. The hydrothermal sediments and the fish debris concentrates have similar REE patterns, characterized by a LREE enrichment and a large positive Eu anomaly.more » This REE pattern is also observed in E.P.R. hydrothermal solutions. Fish debris from marine environments acquire their REE content and signature mostly from sea water during early diagenesis. The hydrothermal REE signature of Atlantis II Deep fish debris indicate that they probably record the REE signature of their hydrothermal sedimentation and diagenetic environment. The different REE signatures of the Shaban/Jean Charcot and Atlantis II Deep hydrothermal sediments suggest a sea water-dominated brine in the Shaban/Jean Charcot Deep as opposed to the predominantly hydrothermal brine in Atlantis II Deep. Atlantis II Deep fish debris are also characterized by their high U but low Th contents. Their low Th contents probably reflect the low Th content of the various possible sources (sea water, brine, sediments). Their U contents are probably controlled by the redox conditions of sedimentation.« less

An anterior ankle-foot orthosis improves walking economy in Charcot-Marie-Tooth type 1A patients.

Ankle-foot orthoses are commonly prescribed in Charcot-Marie-Tooth type 1A disease to improve quality of walking and reduce the risk of falling due to the foot drop. This study aimed at assessing the effect of an anterior ankle-foot orthosis on walking economy in a group of Charcot-Marie-Tooth type 1A patients. Within-group comparisons. 7 Charcot-Marie-Tooth type 1A patients (four women and three men; 37 ± 11 years; age range = 22-53 years) were asked to walk on a circuit at their self-selected speeds ('slow', 'comfortable' and 'fast') in two walking conditions: (1) with shoes only and (2) with Taloelast(®) anterior elastic ankle-foot orthoses. Speed of walking and metabolic cost of walking energy cost per unit of distance were assessed at the three self-selected speeds of walking for both walking conditions. Speed of walking at the three self-selected speeds did not differ between shoes only and anterior elastic ankle-foot orthoses, whereas walking energy cost per unit of distance at comfortable speed was lower in patients using anterior elastic ankle-foot orthoses with respect to shoes only (2.39 ± 0.22 vs 2.70 ± 0.19 J kg(-1) m(-1); P < 0.05). In Charcot-Marie-Tooth type 1A patients, the use of anterior elastic ankle-foot orthoses improved walking economy by reducing the energy cost of walking per unit of distance, thus reflecting a lower level of metabolic effort and improved mechanical efficiency in comparison with shoes only. From a practical perspective, Charcot-Marie-Tooth type 1A patients with anterior elastic ankle-foot orthoses can walk for a longer duration with a lower level of physical effort. Improvements in walking economy due to ankle-foot orthoses are likely a consequence of the reduction in steppage gait. © The International Society for Prosthetics and Orthotics 2013.

We present new optical and NIR photometric data in the VRIJHK and H-α bands for the cluster NGC 1893. The optical photometry was obtained by using images acquired in service mode using two different telescopes: the Device Optimized for the LOw RESolution (DOLORES) mounted on the Telescopio Nazionale Galileo (TNG), used in service mode during three nights in 2007, and the Calar Alto Faint Object Spectrograph (CAFOS), mounted on the 2.2m telescope in Calar Alto German-Spanish Observatory (Spain), during three nights in 2007 and 2008. NIR observations were acquired in service mode at the TNG, using the large field Near Infrared Camera Spectrometer (NICS) with the Js(1.25um), H(1.63um) and K'(2.12um) filters during eight nights in 2007 and 2008. We observed a field around NGC 1893 with a raster of 4x4 pointings, at each pointing we obtained a series of NINT dithered exposures. Each exposure is a repetition of a DIT (Detector Integration Time) times NDIT (number of DIT), to avoid saturation of the background. (4 data files).

Jeans instability in a universe with dissipation

NASA Astrophysics Data System (ADS)

Kremer, Gilberto M.; Richarte, Martín G.; Teston, Felipe

2018-01-01

The problem of Jeans gravitational instability is investigated for static and expanding universes within the context of the five and thirteen field theories which account for viscous and thermal effects. For the five-field theory a general dispersion relation has been derived with the help of relevant linearized perturbation equations, showing that the shear viscosity parameter alters the propagating modes for large and small wavelengths. The behavior of density and temperature contrasts are analyzed for the hard-sphere model in detail. In the small wavelengths regime, increasing the amount of shear viscosity into the system forces the harmonic perturbations to damp faster, however, in the opposite limit larger values of shear viscosity lead to smaller values of density and temperature contrasts. We also consider the hyperbolic case associated with the thirteen-field theory which involves two related parameters, namely the shear viscosity and the collision frequency, the last one is due to the production terms which appear in the Grad method. The dispersion relation becomes a polynomial in the frequency with two orders higher in relation to the five-field theory, indicating that the effects associated with the shear viscosity and heat flux are nontrivial. The profile of Jeans mass in terms of the temperature and number density is explored by contrasting with several data of molecular clouds. Regarding the dynamical evolution of the density, temperature, stress and heat flux contrasts for a universe dominated by pressureless matter, we obtain also damped harmonic waves for small wavelengths. In the case of large wavelengths, the density and temperature contrasts grow with time (due to the Jeans mechanism) while the stress and heat flux contrasts heavily decay with time. For an expanding universe, the Jeans mass and Jeans length are obtained and their physical consequences are explored.

A key moment in the history of psychiatry occurred during Charcot's time at La Salpêtriere. Though his studies on hysteria and hypnotism, the founder of neurology inspired the work of two of his alumni: a Viennese Nervenartz and a French philosopher interested in the dissociation of personality. Even though neither of them was originally an alienist, their respective work allowed the field of neurosis--then belonging to internal medicine--to pass to psychiatry. The parallel lives of these frères enemis, both of whom were treated differently by fame, developed inside a very complex cultural and scientific milieu. Therefore, it is necessary to consider them together with other physicians, some of whom are much less well-known nowadays, who one way or another carried Charcot's influence into psychiatry, psychology and psychotherapy. The fates of the Dioscuri have been reversed--the fame and success of Freudian psychoanalysis ran parallel to Janet's oblivion and his long 'purgatory', but now the 'renaissance' of his work coincides with the decline of psychoanalysis as a theoretical explanation for mental pathology.

2014-09-15

Jeans instability is examined in detail in uniform dusty magnetoplasmas taking care of collisional and non-zero finite thermal effects in addition to the quantum characteristics arising through the Bohm potential and the Fermi degenerate pressure using the quantum hydrodynamic model of plasmas. It is found that the presence of the dust-lower-hybrid wave, collisional effects of plasma species, thermal effects of electrons, and the quantum mechanical effects of electrons have significance over the Jeans instability. Here, we have pointed out a new class of dissipative instability in quantum plasma regime.

Androgen receptor regulated microRNA miR-182-5p promotes prostate cancer progression by targeting the ARRDC3/ITGB4 pathway

Abstracts: MicroRNAs (miRNAs) are important endogenous gene regulators that play key roles in prostate cancer development and metastasis. However, specific miRNA expression patterns in prostate cancer tissues from Chinese patients remain largely unknown. In this study, we compared miRNA expression patterns in 65 pairs of prostate cancer and para-cancer tissues by RNA sequencing and found that miR-182-5p was the most up-regulated miRNA in prostate cancer tissues. The result was validated using realtime PCR in 18 pairs of prostate cancer and para-cancer tissues. In in vitro analysis, it was confirmed that miR-182-5p promotes prostate cancer cell proliferation, invasion and migration and inhibitmore » apoptosis. In addition, the androgen receptor directly regulated the transcription of miR-182-5p, which could target to the 3′UTR of ARRDC3 mRNA and affect the expression of ARRDC3 and its downstream gene ITGB4. For the in vivo experiment, miR-182-5p overexpression also promoted the growth and progression of prostate cancer tumors. In this regard, we suggest that miR-182-5p may be a key androgen receptor-regulated factor that contributes to the development and metastasis of Chinese prostate cancers and may be a potential target for the early diagnosis and therapeutic studies of prostate cancer. -- Highlights: •miR-182-5p is the mostly up-regulated miRNA in Chinese prostate cancer. •miR-182-5p is regulated by androgen receptor. •miR-182-5p promotes prostate cancer progression. •miR-182-5p regulates ARRDC3/ITGB4 pathway.« less

2015-01-01

This paper examines the role of work in Charcot's clinical teaching focusing on cases of male hysteria in The Tuesday's Lessons from 1887 to 1889. Today, we read the work of Charcot in a retrospective way as having ended in a failure: He would have missed the discovery of the sexual unconscious. From the perspective of psychodynamics of work, it appears an alternative way which was present in Charcot, though unfinished, opening on a possible development of a relationship between psychic and body. The role of work in traumatic hysteria has been forgotten by Freud's posterity and this obliteration continues today.

Charcot arthropathy of the peritalar complex carries a high risk of amputation if not properly managed. Our aim is to assess the functional outcome of severe Charcot arthropathy of the peritalar complex following enblock resection of the ulcer, massive debridement and stabilizing all the elements of the peritalar complex. We prospectively studied 38 feet in 35 patients with peritalar complex Charcot arthropathy. All Feet underwent intense debridement and fusion using a combination of (Ilizarov) external fixation, and (plate and locked nail) internal fixation. Thirty two feet were graded as Eichenholtz 2, and six feet were graded as Eichenholtz 3. The mean follow up was 35.9months. The mean AOFAS score was significantly elevated from 25.4±9.1 preoperatively to 67.6±5.7 at the most recent follow-up (p<0.001). Complete bony fusion was achieved in 28 feet. Unsound bony fusion occurred in 8 feet. Two feet required below knee amputation. Peritalar complex Charcot arthropathy is not uncommon variety. Such cases carry high risk of complications and amputation is not excluded. The proper timing of surgery is crucial. Massive debridement and rigid fixation with strict follow up is mandatory to achieve the ultimate goal of obtaining a plantigrade, stable, mechanically sound, painless and infection free pedal construct.

Jean Francheteau, pioneering marine geologist and geophysicist, AGU Fellow, and emeritus professor at the University of Brest (Université de Bretagne Occidentale), died on 21 July in St-Renan, Brittany, France, at the age of 67 after a long illness. With his passing, the field of Earth sciences lost a major contributor to the development of a definitive theory of plate tectonics and one of the first to make visual geological observations on the deep seafloor. Such scientific accomplishments, coupled with his personal charm and the ability to collaborate with researchers from many institutions, ensured that he had a huge influence not only on the world of research but also on teaching and the application of ethics to science. Jean arrived at Scripps Institution of Oceanography in La Jolla, Calif., in 1966 after obtaining a diploma in mining engineering at the prestigious Éole Nationale Supérieure de la Métallurgie et de l'Industrie des Mines in Nancy, France. He chose Victor Vacquier as his thesis supervisor and began working in Vic's lab with John Sclater, ostensibly on heat flow measurements.

Demonic possession by Jean Lhermitte.

Drouin, E; Péréon, T; Péréon, Y

2017-08-01

The name of the French neurologist and psychiatrist Jean Lhermitte (1877-1959) is most often associated with the sign he described back in 1927 in three patients with multiple sclerosis. We are reporting unpublished handwritten notes by Jean Lhermitte about 'demonic possession', which date from the 1950s. Drawing from his experiences in neuropsychiatry, Lhermitte gathered notable case reviews as well as individual case histories. For him, cases of demonic possession are of a psychiatric nature with social background exerting a strong influence. Like Freud did earlier, Lhermitte believes that the majority of those possessed people have been subjected to sexual trauma with scruples, often linked to religion. Demonic possession cases were not so rare in the 1950s but their number has nowadays declined substantially with the development of modern psychiatry. Copyright © 2017 L'Encéphale, Paris.

Charcot-Marie-Tooth (CMT) disease, the most common inherited peripheral neuropathy, has pain as one of its clinical features, yet it remains underdiagnosed and undertreated. This literature review assessed data related to pain from CMT to determine its prevalence, type and importance as a symptom, which, unlike other symptoms, is likely to be treated. The research encompassed 2007 to 2017 and included five articles that addressed pain from CMT. All of the papers concurred that pain is frequently present in CMT patients, yet its classification remains undefined as there has been no consensus in the literature about the mechanisms that cause it.

2012-08-01

Gross deformity of the foot in Charcot neuroarthropathy can lead to collapse and subsequent ulceration, infection, amputation, or premature death. This study evaluated healing of midfoot ulcerations of Charcot neuroarthropathy using PriMatrix, a novel acellular fetal bovine dermal matrix. In this retrospective analysis, 20 patients with ulcerations of the midfoot associated with Charcot neuroarthropathy were treated with either PriMatrix in addition to standard wound care (PriMatrix group,n = 12) or standard wound care alone (control group, n = 8). All patients had chronic, nonhealing foot ulcerations of at least 2250 mm(3) for a minimum of 30 days duration. All foot ulcerations were full thickness with subcutaneous involvement. Ankle brachial index ≥0.90 and/or transcutaneous oximetry (TcPo(2)) ≥40 mm Hg at the periulcer site was necessary for inclusion. Patients were excluded if they had acute or chronic osteomyelitis of the foot. Demography, risk factors, baseline severity of Charcot neuroarthropathy, and wound volume (control 4078 mm(3), PriMatrix 3737.5 mm(3), P = nonsignificant) were similar between treatment groups. Mean time to healing in the PriMatrix group (116 days, 95% CI = 109-123) was significantly shorter than in the control group (180 days, 95% confidence interval [CI] = 171-188); P < .0001. A significantly faster rate of healing was observed with PriMatrix (87.9 mm(3)/wk, 95% CI = 115.2% to 60.6%) compared with control (59.0 mm(3)/wk, 95% CI = 72.8% to 45.3%); P < .0001). The significantly faster rate of healing and steeper slope of volume reduction in the PriMatrix group warrants further investigation into its effects on healing of neuropathic ulcerations and potential limb salvage.

Some historical reflections on the neural control of locomotion.

PubMed

Clarac, François

2008-01-01

Thought on the neural control of locomotion dates back to antiquity. In this article, however, the focus is more recent by starting with some major 17th century concepts, which were developed by René Descartes, a French philosopher; Thomas Willis, an English anatomist; and Giovanni Borelli, an Italian physiologist and physicist. Each relied on his personal expertise to theorize on the organization and control of movements. The 18th and early 19th centuries saw work on both the central and peripheral control of movement: the former most notably by Johann Unzer, Marie Jean-Pierre Flourens and Julien-Jean-César Legallois, and the latter by Unzer, Jirí Procháska and many others. Next in the 19th century, neurologists used human locomotion as a precise tool for characterizing motor pathologies: e.g., Guillaume Duchenne de Boulogne's description of locomotor ataxia. Jean-Martin Charcot considered motor control to be organized at two levels of the central nervous system: the cerebral cortex and the spinal cord. Maurice Philippson's defined the dog's step cycle and considered that locomotion used both central and reflex mechanisms. Charles Sherrington explained that locomotor control was usually thought to consist of a succession of peripheral reflexes (e.g., the stepping reflexes). Thomas Graham Brown's then contemporary evidence for the spinal origin of locomotor rhythmicity languished in obscurity until the early 1960s. By then the stage was set for an international assault on the neural control of locomotion, which featured research conducted on both invertebrate and vertebrate animal models. These contributions have progressively became more integrated and interactive, with current work emphasizing that locomotor control involves a seamless integration between central locomotor networks and peripheral feedback.

Traditionally, Charcot arthropathy has been considered an absolute contraindication for total hip arthroplasty (THA). However, some recent reports have shown that good short- to mid-term results can be achieved by improving the durability of the implant. This paper reports the mid- to long-term results of THA in two patients with Charcot hip joints caused by congenital insensivity to pain with anhydrosis. Both patients suffered multiple posterior dislocations in the six months immediately following surgery. However, with the continuous use of a hard abduction brace, one patient was eventually able to walk with a lofstrand cane and the other with the use of one crutch. Although one patient experienced a dislocation five years after surgery, X-rays taken after nine years and five years, respectively, revealed no clinical signs of implant loosening. We conclude that, with careful planning and appropriate precautions, THA may be a viable treatment option for Charcot hip joints caused by congenital insensivity to pain with anhydrosis.

THERMALLY DRIVEN ATMOSPHERIC ESCAPE: TRANSITION FROM HYDRODYNAMIC TO JEANS ESCAPE

DOE Office of Scientific and Technical Information (OSTI.GOV)

Volkov, Alexey N.; Johnson, Robert E.; Tucker, Orenthal J.

2011-03-10

Thermally driven escape from planetary atmospheres changes in nature from an organized outflow (hydrodynamic escape) to escape on a molecule-by-molecule basis (Jeans escape) with increasing Jeans parameter, {lambda}, the ratio of the gravitational to thermal energy of the atmospheric molecules. This change is described here for the first time using the direct simulation Monte Carlo method. When heating is predominantly below the lower boundary of the simulation region, R{sub 0}, and well below the exobase of a single-component atmosphere, the nature of the escape process changes over a surprisingly narrow range of Jeans parameters, {lambda}{sub 0}, evaluated at R{sub 0}.more » For an atomic gas, the transition occurs over {lambda}{sub 0} {approx} 2-3, where the lower bound, {lambda}{sub 0} {approx} 2.1, corresponds to the upper limit for isentropic, supersonic outflow. For {lambda}{sub 0} > 3 escape occurs on a molecule-by-molecule basis and we show that, contrary to earlier suggestions, for {lambda}{sub 0} > {approx}6 the escape rate does not deviate significantly from the familiar Jeans rate. In a gas composed of diatomic molecules, the transition shifts to {lambda}{sub 0} {approx} 2.4-3.6 and at {lambda}{sub 0} > {approx}4 the escape rate increases a few tens of percent over that for the monatomic gas. Scaling by the Jeans parameter and the Knudsen number, these results can be applied to thermally induced escape of the major species from solar and extrasolar planets.« less

We describe 2 patients with X-linked Charcot-Marie-Tooth disease, type 1 (CMTX1) disease and central nervous system manifestations and review 19 cases from the literature. Our first case had not been previously diagnosed with Charcot-Marie-Tooth disease, and the second case, although known to have Charcot-Marie-Tooth disease, was suspected of having CMTX1 after presentation with central nervous system manifestations. The most common central nervous system manifestations were transient and included dysarthria, ataxia, hemiparesis, and tetraparesis resembling periodic paralysis. Of the 21 patients, 19 presented at 21 years of age or younger, implicating CMTX1 with transient central nervous system manifestations as a disorder that predominantly affects children and adolescents. CMTX1 should be included in the differential diagnosis of patients who present with transient central nervous system phenomena, including stroke-like episodes, tetraparesis suggestive of periodic paralysis, dysarthria, ataxia, or combinations of these deficits. Reversible, bilateral, nonenhancing white matter lesions and restricted diffusion on magnetic resonance imaging are characteristic features of the central nervous system phenotype of CMTX1.

The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN). Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated. Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination. Venous contamination following bolus chase MR was higher in patients with CN.

Genetic epidemiology of Charcot-Marie-Tooth disease.

Charcot-Marie-Tooth disease (CMT) is the most common inherited disorder of the peripheral nervous system. The frequency of different CMT genotypes has been estimated in clinic populations, but prevalence data from the general population is lacking. Point mutations in the mitofusin 2 (MFN2) gene has been identified exclusively in Charcot-Marie-Tooth disease type 2 (CMT2), and in a single family with intermediate CMT. MFN2 point mutations are probably the most common cause of CMT2. The CMT phenotype caused by mutation in the myelin protein zero (MPZ) gene varies considerably, from early onset and severe forms to late onset and milder forms. The mechanism is not well understood. The myelin protein zero (P(0) ) mediates adhesion in the spiral wraps of the Schwann cell's myelin sheath. X-linked Charcot-Marie Tooth disease (CMTX) is caused by mutations in the connexin32 (cx32) gene that encodes a polypeptide which is arranged in hexameric array and form gap junctions. Estimate prevalence of CMT. Estimate frequency of Peripheral Myelin Protein 22 (PMP22) duplication and point mutations, insertions and deletions in Cx32, Early growth response 2 (EGR2), MFN2, MPZ, PMP22 and Small integral membrane protein of lysosome/late endosome (SIMPLE) genes. Description of novel mutations in Cx32, MFN2 and MPZ. Description of de novo mutations in MFN2. Our population based genetic epidemiological survey included persons with CMT residing in eastern Akershus County, Norway. The participants were interviewed and examined by one geneticist/neurologist, and classified clinically, neurophysiologically and genetically. Two-hundred and thirty-two consecutive unselected and unrelated CMT families with available DNA from all regions in Norway were included in the MFN2 study. We screened for point mutations in the MFN2 gene. We describe four novel mutations, two in the connexin32 gene and two in the MPZ gene.

This paper treats the Jeans instability improved at the theoretical investigation of the presence of viscosity and resistivity in the porous medium. Following the normal mode analysis using the QMHD model, the dispersion relation is discussed for wave propagation in longitudinal and transverse direction. The Jeans criteria of instability are affected by the presence of porosity. The graphical presentation shows that porosity has a stabilizing effect while resistivity has destabilizing effect in the system.

Dissociation in hysteria and hypnosis: evidence from cognitive neuroscience.

Bell, Vaughan; Oakley, David A; Halligan, Peter W; Deeley, Quinton

2011-03-01

Jean-Martin Charcot proposed the radical hypothesis that similar brain processes were responsible for the unexplained neurological symptoms of 'hysteria', now typically diagnosed as 'conversion disorder' or 'dissociative (conversion) disorder', and the temporary effects of hypnosis. While this idea has been largely ignored, recent cognitive neuroscience studies indicate that (i) hypnotisability traits are associated with a tendency to develop dissociative symptoms in the sensorimotor domain; (ii) dissociative symptoms can be modelled with suggestions in highly hypnotisable subjects; and (iii) hypnotic phenomena engage brain processes similar to those seen in patients with symptoms of hysteria. One clear theme to emerge from the findings is that 'symptom' presentation, whether clinically diagnosed or simulated using hypnosis, is associated with increases in prefrontal cortex activity suggesting that intervention by the executive system in both automatic and voluntary cognitive processing is common to both hysteria and hypnosis. Nevertheless, while the recent literature provides some compelling leads into the understanding of these phenomena, the field still lacks well controlled systematically designed studies to give a clear insight into the neurocognitive processes underlying dissociation in both hysteria and hypnosis. The aim of this review is to provide an agenda for future research.

In 1887, only five years after Jean-Martin Charcot was awarded the Head of Neurology at "La Salpetrière" in Paris, José María Ramos Mejía became the first professor of Neurology in South America, at the School of Medicine of the University of Buenos Aires. Ramos Mejía convoked three assistants, the neuropathologist Christofredo Jakob, the clinician José A. Esteves and José Ingenieros. Hence it followed that Neurology in Argentina took a stand based on a clinical neurology-neuropathology approach (1941-1987) followed by a clinical-semiological attitude, finally inserting itself within the modern times (1987-present) by creating subspecialties. Throughout its history, Argentina has made remarkable contributions to Neurology, such as the diagnosis and pathogenesis of the nervous system involvement occurring in some regional endemic disorders -for instance, Chagas' disease-, the clinical approach to the diagnosis of dementias, and the pathogenesis of extrapyramidal illnesses and other primary degenerative diseases of the central nervous system, mainly amyotrophic lateral sclerosis. On the other hand, in recent years globalization allowed neurologists to participate in international cooperative projects, favoring a swifter development in the practice of this discipline.

Importance of Apolipoprotein A-I in Multiple Sclerosis.

PubMed

Gardner, Lidia A; Levin, Michael C

2015-01-01

Jean-Martin Charcot has first described multiple sclerosis (MS) as a disease of the central nervous system (CNS) over a century ago. MS remains incurable today, and treatment options are limited to disease modifying drugs. Over the years, significant advances in understanding disease pathology have been made in autoimmune and neurodegenerative components. Despite the fact that brain is the most lipid rich organ in human body, the importance of lipid metabolism has not been extensively studied in this disorder. In MS, the CNS is under attack by a person's own immune system. Autoantigens and autoantibodies are known to cause devastation of myelin through up regulation of T-cells and cytokines, which penetrate through the blood-brain barrier to cause inflammation and myelin destruction. The anti-inflammatory role of high-density lipoproteins (HDLs) has been implicated in a plethora of biological processes: vasodilation, immunity to infection, oxidation, inflammation, and apoptosis. However, it is not known what role HDL plays in neurological function and myelin repair in MS. Understanding of lipid metabolism in the CNS and in the periphery might unveil new therapeutic targets and explain the partial success of some existing MS therapies.

Augusto Orrego Luco born in 1848 and dead in 1933 in Valparaiso, was one of the greatest clinicians and researchers of chilean medicine during the late nineteenth and early twentieth century. Besides being a psychiatrist he contributed to literature, history, politics and medicine. He received his medical degree in 1874 and, apart from being an anatomist, soon became interested in mental illnesses. The title of his thesis was "Mental Hallucinations". He worked in the insane asylum after José Ramón Elguero. Later, in 1891, he was the successor of professor Carlos Sazie at the Hospital for Nervous and Mental Illnesses. Orrego Luco was influenced by french neurology of Jean Martin Charcot and taught a preferentially neurological psychiatry, based on the anatomo-clinical method. His original works were on traumatic hysteria, the mechanism of hypnosis, hysterical hemiplegia, causes of mental hallucinations, syphilitic etiology of Tabes and anatomy of cerebral sulci. In his work about mimical neuroses, he considered and obligation not to discriminate between organic and non-organic patients, because both suffer, he claimed. Presently, Orrego Luco is considered the creator and instigator of the Psychiatry chair, turning it into one of the main medical specialties in Chile.

Novel Use of Active Leptospermum Honey for Ringed Fixator Pin Site Care in Diabetic Charcot Deformity Patients.

Open reduction with external fixation (OREF) utilizing fine wire ringed fixators for correction of Charcot deformity has gained popularity over the past decade. Pin site infections are a well-documented complication of external fixation as well as a driver of escalating health care costs. We aimed to demonstrate the safety and efficacy of a novel method of pin site care utilizing active Leptospermum honey-impregnated dressings (MediHoney) in diabetic patients undergoing deformity correction with OREF. Twenty-one diabetic patients with Charcot deformities of the lower extremity were prospectively enrolled and followed for pin site complications following OREF for deformity correction. Active Leptospermum honey dressings were applied at metal-cutaneous interfaces at the end of the OREF procedure and replaced weekly for a total of 8 weeks. Patients were monitored for pin site infections from the time of surgery until external fixator removal. Sixteen consecutive patients receiving standard OREF for Charcot deformities were evaluated retrospectively to serve as a control group. Of the 21 enrolled patients, 19 underwent OREF and followed up throughout the study period. Treated patients had a mean age of 58.5 years and mean body mass index measuring 33.3 kg/m 2 as documented prior to surgery. The 15 patients with hemoglobin A1c labs drawn in the 3 months preceding surgery averaged 7.5. Fixators were removed at an average of 12.1 weeks after adequate bony healing. Of the 244 pin sites in 19 patients, 3 pin sites (1.2% of pins) in 2 patients (10.5% of patients) showed evidence of superficial infection. All infections resolved with oral antibiotics. Infection rates were significantly reduced when compared to the standard care control group. Pilot data in a prospectively collected case series demonstrate safety and efficacy of active Leptospermum honey-impregnated dressings when used for fine wire ringed fixator pin site care in diabetic Charcot deformity patients.

Hysteria conceptions, from ancient Egypt until the 19th century Parisian hospital based studies, are presented from gynaecological and demonological theories to neurological ones. The hysteria protean behavioral disorders based on nervous origin was proposed at the beginning, mainly in Great Britain, by the "enlightenment nerve doctors". The following personages are highlighted: Galen, William, Sydenham, Cullen, Briquet, and Charcot with his School. Charcot who had hysteria and hypnotism probably as his most important long term work, developed his conceptions, initially, based on the same methodology he applied to studies of other neurological disorder. Some of his associates followed him in his hysteria theories, mainly Paul Richer and Gilles de La Tourette who produced, with the master's support, expressive books on Salpêtrière School view on hysteria.

The definition of the clinicopathological entity of amyotrophic lateral sclerosis evolved over half a century. Although the definitive term amyotrophic lateral sclerosis that acknowledged both upper and lower motor neuron involvement was attributed to Jean-Martin Charcot in 1874, his initial case was published nearly a decade earlier; and it is accepted that, from at least the 1830s, several others (including Charles Bell, François-Amilcar Aran and Jean Cruveilhier) had already recognized a progressive lower motor neuron-only syndrome within a broader, clinically-defined group of disorders, termed progressive muscular atrophy. Although William Gowers first grouped the three phenotypes of amyotrophic lateral sclerosis, progressive muscular atrophy and progressive bulbar palsy together as part of the same syndrome, the term motor neuron disease, as an over-arching label, was not suggested until nearly a century later by W. Russell Brain. Augustus Jacob Lockhart Clarke (1817–80) is best known for his descriptions of spinal cord anatomy. However, in two detailed case reports from the 1860s, he carried out rigorous post-mortem neuropathological studies of what appear to be classical cases of amyotrophic lateral sclerosis. Furthermore, he recognized the additional involvement of the corticospinal tracts that distinguished this from progressive muscular atrophy. Several aspects of the exquisite clinical histories documented as part of both studies, one by Charles Bland Radcliffe, resonate with contemporary debates concerning the evolution of disease in amyotrophic lateral sclerosis. These ‘past masters’ still have much to teach us. PMID:20576696

Structured Abstract Aims To determine local and systemic markers of inflammation and bone mineral density (BMD) in the foot and central sites in participants with diabetes mellitus and peripheral neuropathy (DMPN) with and without acute Charcot neuropathic osteoarthropathy (CN). Methods Eighteen participants with DMPN and CN and 19 participants without CN had foot temperature assessments, serum markers of inflammation [C-reactive protein, (CRP) and erythrocyte sedimentation rate, (ESR)] and BMD of the foot, hip and lumbar spine at baseline and 1 year follow-up. Results CN foot temperature difference was higher compared to DMPN controls at baseline (4.2 ± 1.9 °F vs. 1.2 ± 0.9 °F, P < 0.01) and after 1 year (2.9 ± 3.2 °F vs. 0.9 ± 1.1 °F, P < 0.01). Serum inflammatory markers in the CN group were greater at baseline and remained elevated 1 year later compared to DMPN controls (CRP, P =0.02, ESR, P = 0.03). All pedal bones’ BMD decreased an average of 3% in the CN foot with no changes in hip or lumbar spine. DMPN controls’ foot, hip and lumbar spine BMD remained unchanged. Conclusions Local and systemic inflammation persists1 year after CN with an accompanying pedal osteolysis that may contribute to mid foot deformity which is the hallmark of the chronic Charcot foot.

Hindfoot arthrodesis with retrograde intramedullary nailing has been described as a surgical strategy to reconstruct deformities of the ankle and hindfoot in patients with Charcot arthropathy. This study presents case series of Charcot arthropathy patients treated with two different retrograde intramedullary straight compression nails in order to reconstruct the hindfoot and assess the results over a mid-term follow-up. We performed a retrospective analysis of 18 consecutive patients and 19 operated feet with Charcot arthropathy who underwent a hindfoot arthrodesis using a retrograde intramedullary compression nail. Patients were ten men and eight women with a mean age of 63.43 years (38.5 to 79.8). We report the rate of limb salvage, complications requiring additional surgery, and fusion rate in both groups. The mean duration of follow-up was 46.36 months (37 to 70). The limb salvage rate was 16 of 19 limbs. Three patients had to undergo below-knee amputation due to persistent infection followed by osteomyelitis resistant to parenteral antibiotic therapy and repeated debridement. Complications including infection, hardware removal, nonunion, and persistent ulcers requiring further intervention were also observed. Postoperative functional scores revealed significant improvement compared with preoperative scores on American Orthopaedic Foot and Ankle Society (AOFAS) - Hindfoot scale, Foot Function Index (FFI), visual analogue scale (VAS), and Foot and Ankle Outcome Score (FAOS). The use of retrograde intramedullary compression nail results in good rates of limb salvage when used for hindfoot reconstruction in patients with Charcot arthropathy.

Charcot Marie Tooth disease (CMT) describes a group of hereditary neuropathies that present with distal weakness, wasting and sensory loss. Small studies indicate that people with CMT have reduced daily activity levels. This raises concerns as physical inactivity increases the risk of a range of co- morbidities, an important consideration in the long-term management of this disease. This study aimed to compare physical activity, patterns of sedentary behavior and overall energy expenditure of people with CMT and healthy matched controls. We compared 20 people with CMT and 20 matched controls in a comparison of physical activity measurement over seven days, using an activity monitor. Patterns of sedentary behavior were explored through a power law analysis. Results showed a decrease in daily steps taken in the CMT group, but somewhat paradoxically, they demonstrate shorter bouts of sedentary activity and more frequent transitions from sedentary to active behaviors. No differences were seen in energy expenditure or time spent in sedentary, moderate or vigorous activity. The discrepancy between energy expenditure and number of steps could be due to higher energy requirements for walking, but also may be due to an over-estimation of energy expenditure by the activity monitor in the presence of muscle wasting. Alternatively, this finding may indicate that people with CMT engage more in activities or movement not related to walking. Implications for Rehabilitation Charcot-Marie-Tooth disease: • People with Charcot-Marie-Tooth disease did not show a difference in energy expenditure over seven days compared to healthy controls, but this may be due to higher energy costs of walking, and/or an over estimation of energy expenditure by the activity monitor in a population where there is muscle wasting. This needs to be considered when interpreting activity monitor data in people with neuromuscular diseases. • Compared to healthy controls, people with Charcot

Jeans instability is examined in magnetized quantum dusty plasmas using the quantum hydrodynamic model. The quantum effects are considered via exchange-correlation potential, recoil effect, and Fermi degenerate pressure, in addition to thermal effects of plasma species. It is found that the electron exchange and correlation potential have significant effects over the threshold value of wave vector and Jeans instability. The presence of electron exchange and correlation effect shortens the time of dust sound that comparatively stabilizes the self gravitational collapse. The results at quantum scale are helpful in understanding the collapse of the self-gravitating dusty plasma systems.

The influence of dust-neutral collisions, polarization force, and electron radiative condensation is analysed on the Jeans (gravitational) instability of partially ionized strongly coupled dusty plasma (SCDP) using linear perturbation (normal mode) analysis. The Boltzmann distributed ions, dynamics of inertialess electrons, charged dust and neutral particles are considered. Using the plane wave solutions, a general dispersion relation is derived which is modified due to the presence of dust-neutral collisions, strong coupling effect, polarization force, electron radiative condensation, and Jeans dust/neutral frequencies. In the long wavelength perturbations, the Jeans instability criterion depends upon strong coupling effect, polarization interaction parameter, and thermal loss,more » but it is independent of dust-neutral collision frequency. The stability of the considered configuration is analysed using the Routh–Hurwitz criterion. The growth rates of Jeans instability are illustrated, and stabilizing influence of viscoelasticity and dust-neutral collision frequency while destabilizing effect of electron radiative condensation, polarization force, and Jeans dust-neutral frequency ratio is observed.

The effect of spin induced magnetization and electrical resistivity incorporating the viscosity of the medium is examined on the Jeans instability of quantum magnetoplasma. Formulation of the system is done by using the quantum magnetohydrodynamic model. The analysis of the problem is carried out by normal mode analysis theory. The general dispersion relation is derived from set of perturbed equations to analyse the growth rate and condition of self-gravitational Jeans instability. To discuss the influence of resistivity, magnetization, and viscosity parameters on Jeans instability, the general dispersion relation is reduced for both transverse and longitudinal mode of propagations. In themore » case of transverse propagation, the gravitating mode is found to be affected by the viscosity, magnetization, resistivity, and magnetic field strength whereas Jeans criterion of instability is modified by the magnetization and quantum parameter. In the longitudinal mode of propagation, the gravitating mode is found to be modified due to the viscosity and quantum correction in which the Jeans condition of instability is influenced only by quantum parameter. The other non-gravitating Alfven mode in this direction is affected by finite electrical resistivity, spin induced magnetization, and viscosity. The numerical study for the growth rate of Jeans instability is carried out for both in the transverse and longitudinal direction of propagation to the magnetic field. The effect of various parameters on the growth rate of Jeans instability in quantum plasma is analysed.« less

Charcot-Marie-Tooth disease (CMT) comprises a large variety of different forms of motor and sensory neuropathies. The most frequent are demyelinating forms (CMT1) and axonal forms (CMT2). The molecular basis of several CMT forms has been clarified during the last 15 years. Since muscle wasting and sensory disturbance are the main features of these syndromes, treatments aim to improve motor impairment and sensory disturbances. Specific treatment trials are rare. The objective was to review systematically all randomised and quasi-randomised studies of any treatment for CMT. We searched the Cochrane Neuromuscular Disease Group Trials Register, MEDLINE (January 1966 to August 2007), EMBASE (January 1980 to August 2007), LILACS (January 1982 to August 2007) for randomised controlled trials of treatment for CMT. We included randomised and quasi-randomised trials of any treatment for people with CMT. Where a study aimed to evaluate the treatment of general neuromuscular symptoms of people with peripheral neuropathy including CMT, we included the study if we were able to identify the effect of treatment in the CMT group. Observational studies and case reports on the treatment of people with CMT were not included. Two review authors (PY and TBB) extracted the data, assessed study quality and performed data extraction independently. Only one trial with only eight participants met all the inclusion criteria and provided the primary outcome measure for this review. In this trial, four participants treated with neurotrophin-3 had more improvement after six months on the Neuropathy Impairment Score, mean difference -9.50 (95% CI -13.77 to -5.23), than those four treated with placebo. Small trials of exercise training, creatine monohydrate, orthoses and purified bovine brain ganglioside injections (Cronassial) showed no significant benefit in people with genetically undefined CMT1 or CMT2. Small trials of exercise, creatine, purified brain gangliosides, and orthoses have been

A kinetic theory of the Jeans instability of a dusty plasma has been developed in the present work. The effect of grain charge fluctuations due to the attachment of electrons and ions to the grain surface has been considered in the framework of Krook's collisional model. We demonstrate that the grain charge fluctuations alter the growth rate of the gravitational collapse of the dusty plasma. The Jeans length has been derived under limiting cases, and its dependence on the attachment frequency is shown. In the absence of gravity, we see that the damping rate of the dust acoustic mode is proportional to the electron-dust collision frequency.

2016-07-01

Internal and external fixation techniques have been described for realignment and arthrodesis of Charcot midfoot deformity. There currently is no consensus on the optimal method of surgical reconstruction. This systematic review compared the clinical results of surgical realignment with internal and external fixation, specifically in regard to return to functional ambulation, ulcer occurrence, nonunion, extremity amputation, unplanned further surgery, deep infection, wound healing problems, peri- or intraoperative fractures, and total cases with any complication. A search of multiple databases for all relevant articles published from January 1, 1990, to March 22, 2014, was performed. A logistic regression model evaluated each of the outcomes and its association with the type of fixation method. The odds of returning to functional ambulation were 25% higher for internal fixation (odds ratio [OR], 1.259). Internal fixation had a 42% reduced rate of ulcer occurrence (OR, 0.578). External fixation was 8 times more likely to develop radiographic nonunion than internal fixation (OR, 8.2). Internal fixation resulted in a 1.5-fold increase in extremity amputation (OR, 1.488), a 2-fold increase in deep infection (OR, 2.068), a 3.4-fold increase in wound healing complications (OR, 3.405), and a 1.5-fold increase in the total number of cases experiencing any complication (OR, 1.525). This was associated with a 20% increase in the need for unplanned further surgery with internal fixation (OR, 1.221). Although internal fixation may decrease the risk of nonunion and increase return to functional ambulation, it had a higher rate of overall complications than external fixation for realignment and arthrodesis of Charcot midfoot deformity.

Charcot-Marie-Tooth disease (CMT) is the most common inherited motor and sensory neuropathy. The neuronal form of this disorder is referred to as Charcot-Marie-Tooth type II disease (CMT2). CMT2 is usually inherited as an autosomal dominant trait with a variable age at onset of symptoms associated with progressive axonal neuropathy. In some families, the locus that predisposes to CMT2 has been demonstrated to map to the distal portion of the short arm of chromosome 1. Other families with CMT2 do not show linkage with 1p markers, suggesting genetic heterogeneity in CMT2. We investigated linkage in a single large kindred with autosomalmore » dominant CMT2. The gene responsible for CMT2 in this kindred (CMT2B) was mapped to the interval between the microsatellite markers D3S1769 and D3S1744 in the 3q13-22 region. Study of additional CMT2 kindreds should serve to further refine the disease gene region and may ultimately lead to the identification of a gene defect that underlies the CMT2 phenotype. 21 refs., 3 figs., 1 tab.« less

Intramedullary compressive nail fixation for the treatment of severe Charcot deformity of the ankle and rear foot.

2006-01-01

Involvement of the ankle joint in Charcot osteoarthropathy may be associated with severe instability and fracture or collapse of the talus. Recalcitrant ulceration may result over the lateral malleolus, increasing the risk of major amputation. This study evaluated ankle arthrodesis with a compressive intramedullary nail in 14 patients with diabetes affected by Charcot of the ankle. The mean patient age was 58 +/- 12 years, and the mean duration of diabetes was 17 +/- 5 years. Transcutaneous oxygen pressures were > or = 50 mm Hg in all patients, indicating a good distal blood supply. A below-knee amputation had previously been suggested because of severe ankle joint instability. None of the patients were able to walk without a brace. Four patients had an ulceration that had healed before the index procedure. All procedures were performed in the quiescent phase of the disease. After a mean follow-up of 18 +/- 4 months, 10 patients (71.4%) achieved a solid arthrodesis, returning to walking with protective shoes. Three patients (21.4%) developed breakage of the calcaneus screws, necessitating removal of the screws in 2 cases and removal of the entire nail in 2 cases. These 3 patients went on to fibrous union that allowed walking with a brace. One patient (7.2%) required a below-knee amputation because of postoperative osteomyelitis of the distal tibia. The data from our study demonstrate a high rate of limb salvage (92.8%), suggesting that this device is safe and effective in the treatment of Charcot arthropathy of the ankle.

Defects in mRNA export from the nucleus have been linked to various neurodegenerative disorders. We report mutations in the gene MCM3AP, encoding the germinal center associated nuclear protein (GANP), in nine affected individuals from five unrelated families. The variants were associated with severe childhood onset primarily axonal (four families) or demyelinating (one family) Charcot-Marie-Tooth neuropathy. Mild to moderate intellectual disability was present in seven of nine affected individuals. The affected individuals were either compound heterozygous or homozygous for different MCM3AP variants, which were predicted to cause depletion of GANP or affect conserved amino acids with likely importance for its function. Accordingly, fibroblasts of affected individuals from one family demonstrated severe depletion of GANP. GANP has been described to function as an mRNA export factor, and to suppress TDP-43-mediated motor neuron degeneration in flies. Thus our results suggest defective mRNA export from nucleus as a potential pathogenic mechanism of axonal degeneration in these patients. The identification of MCM3AP variants in affected individuals from multiple centres establishes it as a disease gene for childhood-onset recessively inherited Charcot-Marie-Tooth neuropathy with intellectual disability. © The Author (2017).

The Jeans self-gravitational instability is studied for quantum plasma composed of weakly coupled degenerate electron fluid and non-degenerate strongly coupled ion fluid. The formulation for such system is done on the basis of two fluid theory. The dynamics of weakly coupled degenerate electron fluid is governed by inertialess momentum equation. The quantum forces associated with the quantum diffraction effects and the quantum statistical effects act on the degenerate electron fluid. The strong correlation effects of ion are embedded in generalized viscoelastic momentum equation including the viscoelasticity and shear viscosities of ion fluid. The general dispersion relation is obtained using themore » normal mode analysis technique for the two regimes of propagation, i.e., hydrodynamic and kinetic regimes. The Jeans condition of self-gravitational instability is also obtained for both regimes, in the hydrodynamic regime it is observed to be affected by the ion plasma oscillations and quantum parameter while in the kinetic regime in addition to ion plasma oscillations and quantum parameter, it is also affected by the ion velocity which is modified by the viscosity generated compressional effects. The Jeans critical wave number and corresponding critical mass are also obtained for strongly coupled quantum plasma for both regimes.« less

The effect of suspended particles on Jean's criterion for gravitational instability

Wollkind, David J.; Yates, Kemble R.

1990-01-01

The effect that the proper inclusion of suspended particles has on Jeans' criterion for the self-gravitational instability of an unbounded nonrotating adiabatic gas cloud is examined by formulating the appropriate model system, introducing particular physically plausible equations of state and constitutive relations, performing a linear stability analysis of a uniformly expanding exact solution to these governing equations, and exploiting the fact that there exists a natural small material parameter for this problem given by N sub 1/n sub 1, the ratio of the initial number density for the particles to that for the gas. The main result of this investigation is the derivation of an altered criterion which can substantially reduce Jeans' original critical wavelength for instability. It is then shown that the existing discrepancy between Jeans' theoretical prediction using and actual observational data relevant to the Andromeda nebula M31 can be accounted for by this new criterion of assuming suspended particles of a reasonable grain size and distribution to be present.

MiR-182-5p, as a member of miRNA family, can be detected in lung cancer and plays an important role in lung cancer. To explore the clinical value of miR-182-5p in lung squamous cell carcinoma (LUSC) and to unveil the molecular mechanism of LUSC. The clinical value of miR-182-5p in LUSC was investigated by collecting and calculating data from The Cancer Genome Atlas (TCGA) database, the Gene Expression Omnibus (GEO) database, and real-time quantitative polymerase chain reaction (RT-qPCR). Twelve prediction platforms were used to predict the target genes of miR-182-5p. Protein-protein interaction (PPI) networks and gene ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were used to explore the molecular mechanism of LUSC. The expression of miR-182-5p was significantly over-expressed in LUSC than in non-cancerous tissues, as evidenced by various approaches, including the TCGA database, GEO microarrays, RT-qPCR, and a comprehensive meta-analysis of 501 LUSC cases and 148 non-cancerous cases. Furthermore, a total of 81 potential target genes were chosen from the union of predicted genes and the TCGA database. GO and KEGG analyses demonstrated that the target genes are involved in pathways related to biological processes. PPIs revealed the relationships between these genes, with EPAS1, PRKCE, NR3C1, and RHOB being located in the center of the PPI network. MiR-182-5p upregulation greatly contributes to LUSC and may serve as a biomarker in LUSC.

Let Ω be an unbounded domain in R× Rd. A positive harmonic function u on Ω that vanishes on the boundary of Ω is called a Martin function. In this note, we show that, when Ω is convex, the superlevel sets of a Martin function are also convex. As a consequence we obtain that if in addition Ω has certain symmetry with respect to the t-axis, and partial Ω is sufficiently flat, then the maximum of any Martin function along a slice Ω \\cap ({t}× R^d) is attained at (t, 0).

Sigmund Freud and hysteria: the etiology of psychoanalysis?

PubMed

Bogousslavsky, Julien; Dieguez, Sebastian

2014-01-01

Sigmund Freud developed a specific interest in hysteria after his stay with Professor Jean-Martin Charcot during the winter of 1885-1886, although his previous activity mainly consisted of neuropathology and general medical practice. Most of his initial studies on hysteria (hysteria in men, influence of subconscious ideas, role of traumas, and psychological and sexual factors) were indeed 'borrowed' from Charcot and his immediate followers, such as Pierre Janet and Paul Richer. Subsequently, Freud developed with Breuer a theory of hysteria which encompassed a mixture of Janet's 'fixed subconscious ideas' with the 'pathological secret' concept of Moriz Benedikt. After their book Studies on Hysteria (1895), Freud interrupted his collaboration with Breuer and developed the concept of conversion of psychological problems into somatic manifestations, with a strong 'sexualization' of hysteria. Firstly, he believed that actual abuses had occurred in these patients (the 'seduction' theory), but then blamed them for having deceived him on that issue, so that he subsequently launched a 'fantasy' theory to explain the development of hysterical symptoms without the necessity of actual abuses. Like many of his contemporaries, and contrary to his claims, Freud did not follow a scientific process of verified experiments, but rather adapted his theories to the evolution of his own beliefs on psychological conditions, selectively emphasizing the aspects of his 'therapies' with patients which supported his emerging ideas, with often abrupt changes in theoretical interpretations. While it remains difficult to get a clear, synthetic vision of what was Freud's definite theory of hysteria, it is obvious that hysteria really was the origin of what would become Freud's psychoanalytical theory. Indeed, psychoanalysis appears to have been initially developed by him largely in order to absorb and explain his many changes in the interpretation of hysterical manifestations.

Connexin mutations in X-linked Charcot-Marie-Tooth disease

DOE Office of Scientific and Technical Information (OSTI.GOV)

1993-12-24

X-linked Charcot-Marie-Tooth disease (CMTX) is a form of hereditary neuropathy with demyelination. Recently, this disorder was mapped to chromosome Xq13.1. The gene for the gap junction protein connexin32 is located in the same chromosomal segment, which led to its consideration as a candidate gene for CMTX. With the use of Northern (RNA) blot and immunohistochemistry techniques, it was found that connexin32 is normally expressed in myelinated peripheral nerve. Direct sequencing of the connexin32 gene showed seven different mutations in affected persons from eight CMTX families. These findings, a demonstration of inherited defects in a gap junction protein, suggest that connexin32more » plays an important role in peripheral nerve.« less

Follow up of MRI bone marrow edema in the treated diabetic Charcot foot – a review of patient charts

PubMed Central

Chantelau, Ernst-A.; Zweck, Brigitte; Haage, Patrick

2018-01-01

ABSTRACT Background: Ill-defined areas of water-like signal on bone magnetic resonance imaging (MRI), characterized as bone marrow edema or edema-equivalent signal-changes (EESC), is a hallmark of active-stage pedal neuro-osteoarthropathy (Charcot foot) in painless diabetic neuropathy, and is accompanied by local soft-tissue edema and hyperthermia. The longitudinal effects on EESC of treating the foot in a walking cast were elucidated by reviewing consecutive cases of a diabetic foot clinic. Study design: Retrospective observational study, chart review Material and methods: Cases with active-stage Charcot foot were considered, in whom written reports on baseline and follow-up MRI studies were available for assessment. Only cases without concomitant infection or skin ulcer were chosen, in whom both was documented, onset of symptomatic foot swelling and patient compliance with cast treatment. Results: From 1994 to 2017, 45 consecutive cases in 37 patients were retrieved, with 95 MRI follow-up studies (1–6 per case, average interval between studies 13 weeks). Decreasing EESC was documented in 66/95 (69%) follow-up studies. However, 29/95 (31%) studies revealed temporarily increasing, migrating or stagnating EESC. Conclusion: EESC on MRI disappear in response to prolonged offloading and immobilizing treatment; however, physiologic as well as pathologic fluctuations of posttraumatic EESC have to be considered when interpreting the MR images. Conventional MRI is useful for surveillance of active-stage Charcot foot recovery. PMID:29713425

Structural Evolution of Martin Crater Thaumasia Planum, Mars

NASA Astrophysics Data System (ADS)

Dolan, Daniel J.

A detailed structural map of the central uplift of Martin Crater in western Thaumasia Planum, Mars, reveals highly folded and fractured geology throughout the 15-km diameter uplift. The stratigraphy in the central uplift of the crater has been rotated to near vertical dip and imaged by high-definition cameras aboard the Mars Reconnaissance Orbiter (MRO). These unique factors allow individual geologic beds in Martin Crater to be studied and located across the length of the uplift. Bedding in Martin Crater primarily strikes SSE-NNW and dips near vertically. Many units are separated by a highly complex series of linear faults, creating megablocks of uplifted material. Faulting is dominantly left-slip in surface expression and strikes SW-NE, roughly perpendicular to bedding, and major fold axes plunge toward the SW. Coupled with infrared imagery of the ejecta blanket, which shows an "exclusion zone" northeast of the crater, these structural indicators provide strong support for a low-angle impactor (approximately 10-20°) originating from the northeast. Acoustic fluidization is the prevailing theoretical model put forth to explain complex crater uplift. The theory predicts that uplifted megablocks in craters are small, discrete, separated and highly randomized in orientation. However, megablocks in Martin Crater are tightly interlocked and often continuous in lithology across several kilometers. Thus, the model of acoustic fluidization, as it is currently formulated, does not appear to be supported by the structural evidence found in Martin Crater.

Jean-Antoine Nollet: The father of experimental electrospray.

PubMed

Dumont, Quentin; Cole, Richard B

2014-01-01

The development of electrospray ionization mass spectrometry (ESI-MS) was a 20th century occurrence that underwent rapid acceleration especially in the 1990's. However, long prior to its coupling with mass spectrometry, the electrification of liquids had been studied in a variety of contexts. Although initial reports describing cone formation upon electrification of water drops came out of England, the first true experiments investigating the electrospray phenomenon were performed in the middle of the 18th century by Abbé Jean-Antoine Nollet. The current report, associated with the French Regional Issue of Mass Spectrometry Reviews, examines the contributions of Abbé Nollet to the earliest understanding of the electrospray phenomenon. A description of his accomplishments is placed in the context of the societal and scientific developments of the "Age of Enlightenment" out of which Jean-Antoine Nollet arose. © 2013 Wiley Periodicals, Inc.

Jeans instability in a viscoelastic fluid

DOE Office of Scientific and Technical Information (OSTI.GOV)

Janaki, M. S.; Chakrabarti, N.; Banerjee, D.

2011-01-15

The well known Jeans instability is studied for a viscoelastic gravitational fluid using generalized hydrodynamic equations of motions. It is found that the threshold for the onset of instability appears at higher wavelengths in a viscoelastic medium. Elastic effects playing a role similar to thermal pressure are found to lower the growth rate of the gravitational instability. Such features may manifest themselves in matter constituting dense astrophysical objects.

The January 2006 Volcanic-Tectonic Earthquake Swarm at Mount Martin, Alaska

USGS Publications Warehouse

Dixon, James P.; Power, John A.

2009-01-01

On January 8, 2006, a swarm of volcanic-tectonic earthquakes began beneath Mount Martin at the southern end of the Katmai volcanic cluster. This was the first recorded swarm at Mount Martin since continuous seismic monitoring began in 1996. The number of located earthquakes increased during the next four days, reaching a peak on January 11. For the next two days, the seismic activity decreased, and on January 14, the number of events increased to twice the previous day's total. Following this increase in activity, seismicity declined, returning to background levels by the end of the month. The Alaska Volcano Observatory located 860 earthquakes near Mount Martin during January 2006. No additional signs of volcanic unrest were noted in association with this earthquake swarm. The earthquakes in the Mount Martin swarm, relocated using the double difference technique, formed an elongated cluster dipping to the southwest. Focal mechanisms beneath Mount Martin show a mix of normal, thrust, and strike-slip solutions, with normal focal mechanisms dominating. For earthquakes more than 1 km from Mount Martin, all focal mechanisms showed normal faulting. The calculated b-value for the Mount Martin swarm is 0.98 and showed no significant change before, during, or after the swarm. The triggering mechanism for the Mount Martin swarm is unknown. The time-history of earthquake occurrence is indicative of a volcanic cause; however, there were no low-frequency events or observations, such as increased steaming associated with the swarm. During the swarm, there was no change in the b-value, and the distribution and type of focal mechanisms were similar to those in the period before the anomalous activity. The short duration of the swarm, the similarity in observed focal mechanisms, and the lack of additional signs of unrest suggest this swarm did not result from a large influx of magma within the shallow crust beneath Mount Martin.

Lockheed Martin's Advanced Technology Center (LM-ATC) in Palo Alto, California, has been active in space cryogenic developments for over 30 years. In prior years, work focused on stored cryogen systems for temperatures up to 125 K. As the mechanical cryocoolers matured and demonstrated reliable operation these stored cryogen systems gradually became replaced. LM-ATC is currently developing solid hydrogen systems for temperatures below 7 K [Naes L, Wu S, Cannon J. WISE solid hydrogen cryostat design overview. In: Proceedings of SPIE, cryogenic optical systems and instruments XI, vol. 5904, August, 2005], but these coolers will soon be replaced by mechanical cryocoolers. This paper will present a summary of cryocooler developments at LM-ATC and will describe the recent performance of multiple stage systems. A four-stage pulse tube cryocooler developed under contract to the Jet Propulsion Laboratory (JPL) has been recently developed and operated at 3.8 K [Olson JR, Moore M, Champagne P, Roth E, Evtimov B, Jensen J, et al. Development of a space-type-4-stage pulse tube cryocooler for very low temperatures, Adv Cryogen Engr, vol. 50, Amer Inst of Physics, New York, in press]. Coolers with one, two and three stages have also been widely developed [Nast TC et al. Miniature pulse tube cryocooler for space applications. Cryocoolers, vol. 11. New York: Plenum Press; 2000. p. 145-54; Olson J et al. Development of a 10 K pulse tube cryocooler for space applications. In: Ross R, editor. Cryocoolers, vol. 12.

Gender and sex manifestations in hysteria across medicine and the arts.

PubMed

Dmytriw, Adam A

2015-01-01

The diagnosis of hysteria has existed for at least four-thousand years, with roots in the ancient Greek word hysterikos, referring to diseases of the womb. In the sixteenth-century medical discourses, female hysteria was caused by excess pollution of the womb, with fluids that were labelled 'female sperm' as the probable cause. In the work of Shakespeare, there is a reference to hysterica passio, a term used by King Lear to self-diagnose his affliction. Shakespeare shows how a disease associated with women, and the 'wandering womb' phenomenon could have been spoken of in an associative way. At this time, there is a transformation of the nature of hysteria from a neurological consequence of the sick womb, to sexual deviance. Portrayals of the male deviant would evolve by the Victorian era, concurrent with the diagnosis of 'spermatorrhea'. There are very direct correspondences between the hysteria of spermatorrhea and the notion in Western medicine of the direct links between female hysteria and too much or not enough sexual energy release. Hysteria in both sexes was famously diagnosed and catalogued by Jean-Martin Charcot at the end of the nineteenth century. By the twentieth century, hysteria was also depicted as a disorder of gender as well as sexuality.

The possessions at Loudun: tracking the discourse of dissociation.

PubMed

Stephenson, Craig E

2017-09-01

Embedded in the history of dissociation is the best known case of possession in European history, the 17 th century possessions at Loudun, France (1632-1638). The exorcisms and the trial drew crowds from all over Europe, the outcome prefiguring the direction in which the Western science of mind would be carried. The published debate about the possessed and obsessed Ursuline nuns of Loudun spans four centuries. One can track how theorizing about dissociation changed over time, with psychological contributions by Jean Martin Charcot, Georges Gilles de la Tourette, Pierre Janet, Michel Foucault and Michel de Certeau. Freud's psychoanalytic notion of demonological neurosis emphasized defensive strategies and a diabolic parody of adulthood. Jung's concepts of demonism and possession highlighted dissociated complexes that assimilate the ego and unseat the self, rendering a life 'provisional'. Dissociation as possession provides a through-line in Jung's Collected Works, from his 1902 dissertation to one of the last essays he wrote, in 1961. Within the context of psychotherapy, therapists and patients work towards psychological containment, consciously reorienting themselves to the presence of unconscious factors, personifying, embodying and thereby incorporating images of dissociated Otherness into the experience of selfhood. © 2017, The Society of Analytical Psychology.

Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality.Martin

In this review we focus on Charcot-Marie-Tooth (CMT) neuropathies and hereditary spastic paraplegias (HSPs). Although these diseases differ in whether they primarily affect the peripheral or central nervous system, both are genetically determined, progressive, long axonopathies that affect motor and sensory pathways. This commonality suggests that there might be similarities in the molecular pathology underlying these conditions, and here we compare the molecular genetics and cellular pathology of the two groups.

Because the insight is raising that waste prevention needs an integral product chain approach, a product chain project was awarded with an International Solid Waste Association grant. The project decided to focus on jeans because of the large environmental impacts of cotton and the low recycling rates. The project used an open innovative approach by involving many actors from the different phases of the chain and included student and applied researchers. In a 'design jeans for recycling' students' workshop, prototypes of jeans that are easier to recycle have been developed. Integrating the new generation from different disciplines in the project proved to be very successful. The results show that an open innovation process can lead to very creative ideas and that lessons learned from this project could be used to develop new chain projects for other products. An important condition is that key actors are willing to cooperate in an open innovation approach. © The Author(s) 2014.

The 2,488-MW Martin station is a gas/oil-fired facility that embodies today`s demand for flexible operations, technological advances, and reduced production costs. Martin station first rose up from the Everglades in the early 1980s, with the construction of two 814-MW oil-fired steam plants, Units 1 and 2. Natural-gas-firing capability was added to the balanced-draft, natural-circulation boilers in 1986, increasing the station`s fuel flexibility. Martin then leaped into the headlines in the early 1990s when it added combined-cycle (CC) Units 3 and 4. With this 860-MW expansion, FP and L boldly became the fleet leader for the advanced, 2350F-class 7FA gas turbines.more » Further pushing he technology envelope, the CC includes a three-pressure reheat steam system that raises net plant efficiency for Units 3 and 4 to 54%, on a lower-heating-value (LHV) basis. Incorporating the reheat cycle required significant redesign of the gas-turbine/heat-recovery steam generator (HRSG) train, in order to maintain a rapid startup capability without exceeding metallurgical limits. Perhaps even more important than the technological achievements, Martin stands out from the crowd for its people power, which ensured that the promises of advanced technology actually came to fruition. This station`s aggressive, empowered O and M team shows that you can pioneer technology, reduce operating costs, and deliver high availability--all at the same time.« less

This thematic issue of Comptes rendus Geoscience has been assembled to honor the memory of our late colleague and friend Jean-François Stéphan. Jean-François was a great scientist, specialized in tectonics, and a great colleague who devoted his time for his community. His work and actions deeply imprinted both the French and the International Earth Science communities. This volume brings together contributions of colleagues of Jean-François, who were also close friends or colleagues who knew and deeply appreciated him. Naturally, tectonics is the common theme of these contributions. Some of the papers presented here focus on tectonic questions and/or regions Jean-François worked on during his career; other papers present studies Jean-François motivated or encouraged in one way or another; other papers are simply tectonic studies he would have liked. Taken together, the nine papers of this thematic issue take the reader on a beautiful trip, from past to current tectonics.

Macchia, Giovanni

2014-05-01

This paper deals with two important English scientists of the first half of the twentieth century: Edward Arthur Milne and James Hopwood Jeans. It examines the philosophical reasons that, in 1932, induced Milne to devote himself to the newborn modern cosmology. Among those reasons, it is argued that the most important ones were some of Jeans' philosophical statements regarding the new relativistic view of the expanding universe. In particular, Milne reacted to some confusing idealist opinions expressed by Jeans in the London newspaper The Times, in May 1932, in a debate on the expansion of the universe. Actually, as it will be shown, Jeans received many criticisms about the philosophical reasonings present in all of his popularizing works.

Young people (18-25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, physical activity behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore physical activity (PA) behaviour among 18-25 year olds with influential factors including attitudes, motivators and barriers. An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at university/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial self reported quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted. 1313 questionnaires were analysed. Results from this were incorporated into a qualitative phase also grounded in these theories. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi staged modelling to analyse the quantitative data. 'Framework Analysis' was used to analyse the focus groups. Only 28% of 18-25 year olds achieved recommended levels of PA which decreased with age. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the statistical modelling, positive attitudes toward PA were strong predictors of physical activity associated with being physically active and less sedentary. However, strong intentions to do exercise, was not associated with actual behaviour. Interactive discussions through focus groups unravelled attitudes and barriers influencing PA behaviour. Doing PA to feel good and to enjoy themselves was more important for young people than the common assumptions of 'winning' and 'pleasing others'. Further this age group saw traditional health promotion messages as 'empty' and

To study the clinical and pathological features of Charcot-Marie-Tooth disease (CMT). The general clinical data, the changes of neuroelectrophysiology and the pathological features of neural and muscular biopsy of 20 CMT patients were comprehensively analyzed. The clinical manifestations in the two types of CMT were nearly the same, but the changes of neuroelectrophysiology and the pathological characteristics of the neural and muscular biopsy in the two types were obviously different. 16 cases of CMT type 1 were characterized by decreased sensory nerve conduction velocity (SNCV < 30 m/s) and are associated with demyelinating hypertrophic neuropathy. 4 cases of CMT tylpe 2 were characterized by normal SNCV and associated with axonopathy. Neuroelectrophysiology and neural and muscular biopsy are important for the diagnosis of CMT.

Charcot neuroarthropathy of the foot/ankle is a devastating complication of diabetes. Along with neuroarthropathy, osteomyelitis can occur which can result in amputation. This prospective study evaluated a limb salvage procedure as an alternative to amputation through surgical treatment of osteomyelitis of the midfoot or the ankle and stabilization with external fixation. Forty-five patients with Charcot arthropathy and osteomyelitis underwent debridement and attempted fusion with an external fixator. Chart and radiograph review was performed to assess the success of the fusion and eradication of infection. Out of 45 patients, 39 patients healed using emergent surgery to drain an acute manifestation of the infection while maintaining the fixation for an average of 25.7 weeks. Two patients were treated with intramedullary nail in a subsequent surgical procedure. In four patients, the infection could not be controlled, therefore a major amputation was carried out. For select patients, external fixation proved to be a reasonable alternative to below-knee amputation.

Physical interpretation of Jeans instability in quantum plasmas

Akbari-Moghanjoughi, M.; International Centre for Advanced Studies in Physical Sciences and Institute for Theoretical Physics, Ruhr University Bochum, D-44780 Bochum

In this paper, we use the quantum hydrodynamics and its hydrostatic limit to investigate the newly posed problem of Jeans instability in quantum plasmas from a different point of view in connection with the well-known Chandrasekhar mass-limit on highly collapsed degenerate stellar configurations. It is shown that the hydrodynamic stability of a spherically symmetric uniform quantum plasma with a given fixed mass is achieved by increase in its mass-density or decrease in the radius under the action of gravity. It is also remarked that for masses beyond the limiting Jeans-mass, the plasma becomes completely unstable and the gravitational collapse wouldmore » proceed forever. This limiting mass is found to depend strongly on the composition of the quantum plasma and the atomic-number of the constituent ions, where it is observed that heavier elements rather destabilize the quantum plasma hydrodynamically. It is also shown that the Chandrasekhar mass-limit for white dwarf stars can be directly obtained from the hydrostatic limit of our model.« less

A New Method to Directly Measure the Jeans Scale of the Intergalactic Medium Using Close Quasar Pairs

NASA Astrophysics Data System (ADS)

Rorai, Alberto; Hennawi, Joseph F.; White, Martin

2013-10-01

Although the baryons in the intergalactic medium (IGM) trace dark matter fluctuations on megaparsec scales, on smaller scales ~100 kpc, fluctuations are suppressed because the finite temperature gas is pressure supported against gravity, analogous to the classical Jeans argument. This Jeans filtering scale, which quantifies the small-scale structure of the IGM, has fundamental cosmological implications. First, it provides a thermal record of heat injected by ultraviolet photons during cosmic reionization events, and thus constrains the thermal and reionization history of the universe. Second, the Jeans scale determines the clumpiness of the IGM, a critical ingredient in models of cosmic reionization. Third, it sets the minimum mass scale for gravitational collapse from the IGM, and hence plays a pivotal role in galaxy formation. Unfortunately, it is extremely challenging to measure the Jeans scale via the standard technique of analyzing purely longitudinal Lyα forest spectra, because the thermal Doppler broadening of absorption lines along the line-of-sight, is highly degenerate with Jeans smoothing. In this work, we show that the Jeans filtering scale can be directly measured by characterizing the coherence of correlated Lyα forest absorption in close quasar pairs, with separations small enough ~100 kpc to resolve it. We present a novel technique for this purpose, based on the probability density function (PDF) of phase angle differences of homologous longitudinal Fourier modes in close quasar pair spectra. A Bayesian formalism is introduced based on the phase angle PDF, and Markov Chain Monte Carlo techniques are used to characterize the precision of a hypothetical Jeans scale measurement, and explore degeneracies with other thermal parameters governing the IGM. A semi-analytical model of the Lyα forest is used to generate a large grid (500) of thermal models from a dark matter only simulation.

ISM gas studies towards the TeV PWN HESS J1825-137 and northern region

NASA Astrophysics Data System (ADS)

Voisin, F.; Rowell, G.; Burton, M. G.; Walsh, A.; Fukui, Y.; Aharonian, F.

2016-05-01

HESS J1825-137 is a pulsar wind nebula (PWN) whose TeV emission extends across ˜1 . Its large asymmetric shape indicates that its progenitor supernova interacted with a molecular cloud located in the north of the PWN as detected by previous CO Galactic survey (e.g. Lemiere, Terrier & Djannati-Ataï). Here, we provide a detailed picture of the interstellar medium (ISM) towards the region north of HESS J1825-137, with the analysis of the dense molecular gas from our 7 and 12 mm Mopra survey and the more diffuse molecular gas from the Nanten CO(1-0) and GRS 13CO(1-0) surveys. Our focus is the possible association between HESS J1825-137 and the unidentified TeV source to the north, HESS J1826-130. We report several dense molecular regions whose kinematic distance matched the dispersion measured distance of the pulsar. Among them, the dense molecular gas located at (RA, Dec.) = (18h421h,-13.282°) shows enhanced turbulence and we suggest that the velocity structure in this region may be explained by a cloud-cloud collision scenario. Furthermore, the presence of a H α rim may be the first evidence of the progenitor supernova remnant (SNR) of the pulsar PSR J1826-1334 as the distance between the H α rim and the TeV source matched with the predicted SNR radius RSNR ˜ 120 pc. From our ISM study, we identify a few plausible origins of the HESS J1826-130 emission, including the progenitor SNR of PSR J1826-1334 and the PWN G018.5-0.4 powered by PSR J1826-1256. A deeper TeV study however, is required to fully identify the origin of this mysterious TeV source.

Three Decades Investigating Humor and Laughter: An Interview With Professor Rod Martin.

Martin, Rod; Kuiper, Nicholas A

2016-08-01

Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

Effect of polarization force on the Jeans instability in collisional dusty plasmas

2018-03-01

The Jeans instability in collisional dusty plasmas has been analytically investigated by considering the polarization force effect. Instabilities due to dust-neutral and ion-neutral drags can occur in electrostatic waves of collisional dusty plasmas with self-gravitating particles. In this study, the effect of gravitational force on heavy dust particles is considered in tandem with both the polarization and electrostatic forces. The theoretical framework has been developed and the dispersion relation and instability growth rate have been derived, assuming the plane wave approximation. The derived instability growth rate shows that, in collisional dusty plasmas, the Jeans instability strongly depends on the magnitude of the polarization force.

Kinematic evidence for feedback-driven star formation in NGC 1893

OB associations are the prevailing star-forming sites in the Galaxy. Up to now, the process of how OB associations were formed remained a mystery. A possible process is self-regulating star formation driven by feedback from massive stars. However, although a number of observational studies uncovered various signposts of feedback-driven star formation, the effectiveness of such feedback has been questioned. Stellar and gas kinematics is a promising tool to capture the relative motion of newborn stars and gas away from ionizing sources. We present high-resolution spectroscopy of stars and gas in the young open cluster NGC 1893. Our findings show that newborn stars and the tadpole nebula Sim 130 are moving away from the central cluster containing two O-type stars, and that the time-scale of sequential star formation is about 1 Myr within a 9 pc distance. The newborn stars formed by feedback from massive stars account for at least 18 per cent of the total stellar population in the cluster, suggesting that this process can play an important role in the formation of OB associations. These results support the self-regulating star formation model.

Effect of rotation on Jeans instability of magnetized radiative quantum plasma

NASA Astrophysics Data System (ADS)

Joshi, H.; Pensia, R. K.

2017-03-01

The influence of rotation on the Jeans instability of homogeneous magnetized radiative quantum plasma is investigated. The basic equations of the problem are constructed and linearized by using the Quantum Magnetohydrodynamics (QMHD) model. The general dispersion relation is obtained by using the normal mode analysis technique, which is reduced for both the transverse and the longitudinal mode of propagations and further it is reduced for the axis of rotation parallel and perpendicular to the magnetic field. We found that the stabilizing effects of rotation are decreases for a strong magnetic field which is shown in the graphical representation. We also found that the quantum correction modified the condition of Jeans instability in both modes of propagation. The stabilizing effect of rotation is more increased in the presence of quantum correction.

Biological and epistemological models of localization in the nineteenth century: from Gall to Charcot.

PubMed

Kaitaro, T

2001-12-01

In the latter half of the nineteenth century, the localizationist doctrines became closely associated with the memory trace paradigm. The analysis of the texts dealing with the localization and the nature of 'the loss of articulated speech' (motor aphasia) by Bouillaud, Lordat, Dax, Broca, Trousseau, Baillarger, Charcot and Wernicke shows how the biological paradigm of localization presented by Gall and based on the notion of organ-function correspondence was transformed into a model based on localizable memory traces. This change resulted in the theoretical unification of the mechanisms of motor and non-motor forms of aphasia. These forms, which the earlier authors tended to separate in their analyses of the underlying mechanisms, were now regarded as involving similar mechanisms related to the loss of mnestic images. The crucial step in this development was taken by Broca who presented the hypothesis that the faculty of coordination of speech movements, which according to his predecessors was the faculty lost in motor aphasia, was actually an intellectual faculty and a specific form of memory, and motor aphasia consequently a selective kind of amnesia. Theorists like Charcot and Wernicke generalized this idea into a comprehensive theory of the nature of localization based on the notion of memory traces. Thus, the localization of function was reduced to the localization of representations. Instead of biological paradigms, this model of localization is rooted in the epistemological tradition of psychology represented by Locke and Condillac, who were primarily interested in the problem of representation. In physiology, this approach usually resulted in attempts at localizing representations instead of functions.

The effect of finite Larmor radius corrections on Jeans instability of quantum plasma

The influence of finite Larmor radius (FLR) effects on the Jeans instability of infinitely conducting homogeneous quantum plasma is investigated. The quantum magnetohydrodynamic (QMHD) model is used to formulate the problem. The contribution of FLR is incorporated to the QMHD set of equations in the present analysis. The general dispersion relation is obtained analytically using the normal mode analysis technique which is modified due to the contribution of FLR corrections. From general dispersion relation, the condition of instability is obtained and it is found that Jeans condition is modified due to quantum effect. The general dispersion relation is reduced formore » both transverse and longitudinal mode of propagations. The condition of gravitational instability is modified due to the presence of both FLR and quantum corrections in the transverse mode of propagation. In longitudinal case, it is found to be unaffected by the FLR effects but modified due to the quantum corrections. The growth rate of Jeans instability is discussed numerically for various values of quantum and FLR corrections of the medium. It is found that the quantum parameter and FLR effects have stabilizing influence on the growth rate of instability of the system.« less

Tribute to Jean-Marie Mariotti

Jean-Marie Mariotti (1955 - 1998) prematurely passed away after too short a career of optician and astronomer. With his students, his contributions to the nascent field of high angular resolution at optical wavelengths, and especially to interferometry, both on the ground and in space, have been remarkable. Pioneering the use of single-mode optical fibers and integrated optics, he pushed the accuracy of visibility (amplitude) measurements to a fraction of a percent. His vision of a Mauna Kea kilometric interferometer using the existing giant telescopes is now becoming a reality with the 'OHANA project. His role in the emergence of the Very Large Telescope Interferometer (VLTI) and in the birth of the space mission DARWIN for exoplanets studies has been essential.

There is a rich tradition of writings about the foundation of psychology laboratories, particularly in the United States but also in France. Various documents exist concerning former German laboratories in American and French literature. But the most interesting French paper was certainly written by a young psychologist named Victor Henri (1872-1940) who was a close collaborator of Alfred Binet (1857-1911) in the 1890s. Visiting various psychology laboratories, he wrote, in 1893, a clear description of the laboratories of Wundt, G. E. Müller, Martius and Ebbinghaus. An English translation is given of Henri's paper and the historical importance of his contribution is here expounded by contrasting the German and French psychologies of the time.

Olson, Jeffrey R.; Roth, Eric W.; Sanders, Lincoln-Shaun; Will, Eric; Frank, David J.

2017-05-01

Lockheed Martin's Advanced Technology Center, part of Lockheed Martin Space Systems Company, has developed a series of long life microcryocoolers for avionics and space sensor applications. We report the development and testing of three varieties of single-stage, compact, coaxial, pulse tube microcryocoolers. These coolers support emerging large, high operating temperature (100-150K) infrared focal plane array sensors with nominal cooling loads of 200-2000 mW, and all share long life technology attributes used in space cryocoolers, which typically provide 10 years of continuous operation on orbit without degradation. These three models of microcryocooler are the 345 gram Micro1-1, designed to provide 1 W cooling at 150 K, the 450 gram Micro1-2, designed to provide 2 W cooling at 105 K, and the 320 gram Micro1-3, designed to provide 300 mW cooling at 125 K while providing the capability to cool the IR focal plane to 125 K in less than 3 minutes. The Micro1-3 was also designed with a highly compact package that reduced the coldhead length to 55 mm, a length reduction of more than a factor of two compared with the other coldheads. This paper also describes recent design studies of 2-stage microcryocoolers capable of providing cooling at 25-100K. LMSSC is an industry leader in multiple-stage coolers, having successfully built and tested eight 2-stage coolers (typically cooling to 35-55K), and four coolers with 3 or 4 stages (for cooling to 4-10K). The 2-stage microcryocooler offers a very low mass and compact package capable of cooling HgCdTe focal planes, while providing simultaneous optics cooling at a higher temperature.

Orbital Space Plane (OSP) Program at Lockheed Martin

Ford, Robert

2003-01-01

Lockheed Martin has been an active participant in NASA's Space Launch Initiative (SLI) programs over the past several years. SLI, part of NASA's Integrated Space Transportation Plan (ISTP), was restructured in November 2002 to focus the overall theme of safer, more affordable space transportation along two paths the Orbital Space Plane (OSP) and the Next Generation Launch Technology programs. The Orbital Space Plane program has the goal of providing rescue capability from the International Space Station by 2008 or earlier and transfer capability for crew (and contingency cargo) by 2012. The Next Generation Launch Technology program is combining research and development efforts from the 2d Generation Reusable Launch Vehicle (2GRLV) program with cutting-edge, advanced space transportation programs (previously designated 31d Generation) into one program aimed at enabling safe, reliable, cost-effective reusable launch systems by the middle of the next decade. Lockheed Martin is one of three prime contractors working to bring Orbital Space Plane system concepts to a system design level of maturity by December 2003. This paper and presentation will update the aerospace community on the progress of the OSP program, from an industry perspective, and provide insights into Lockheed Martin's role in enabling the vision of a safer, more affordable means of taking people to and from space.

Late Corrective Arthrodesis in Nonplantigrade Diabetic Charcot Midfoot Disease Is Associated with High Complication and Reoperation Rates

PubMed Central

Wussow, Annekatrin

2015-01-01

Introduction. Charcot arthropathy may lead to a loss of osteoligamentous foot architecture and consequently loss of the plantigrade alignment. In this series of patients a technique of internal corrective arthrodesis with maximum fixation strength was provided in order to lower complication rates. Materials/Methods. 21 feet with severe nonplantigrade diabetic Charcot deformity Eichenholtz stages II/III (Sanders/Frykberg II/III/IV) and reconstructive arthrodesis with medial and additional lateral column support were retrospectively enrolled. Follow-up averaged 4.0 years and included a clinical (AOFAS score/PSS), radiological, and complication analysis. Results. A mean of 2.4 complications/foot occurred, of which 1.5/foot had to be solved surgically. 76% of feet suffered from soft tissue complications; 43% suffered hardware-associated complications. Feet with only 2 out of 5 high risk criteria according to Pinzur showed significantly lower complication counts. Radiographs revealed a correct restoration of all foot axes postoperatively with superior fixation strength medially. Conclusion. Late corrective arthrodesis with medial and lateral column stabilization in the nonplantigrade stages of neuroosteoarthropathy can provide reasonable reconstruction of the foot alignment. Nonetheless, overall complication/reoperation rates were high. With separation into low/high risk criteria a helpful guide in treatment choice is provided. This trial is registered with German Clinical Trials Register (DRKS) under number DRKS00007537. PMID:26000309

Linkage localization of X-linked Charcot-Marie-Tooth disease

Bergoffen, J.; Trofatter, J.; Haines, J.L.

1993-02-01

Charcot-Marie-Tooth disease (CMT), also known as hereditary motor and sensory neuropathy, is a heterogeneous group of slowly progressive, degenerative disorders of peripheral nerve. X-linked CMT (CMTX) (McKusick 302800), a subdivision of type I, or demyelinating, CMT is an X-linked dominant condition with variable penetrance. Previous linkage analysis using RFLPs demonstrated linkage to markers on the proximal long and short arms of the X chromosome, with the more likely localization on the proximal long arm of the X chromosome. Available variable simple-sequence repeats (VSSRs) broaden the possibilities for linkage analysis. This paper presents new linkage data and recombination analysis derived frommore » work with four VSSR markers - AR, PGKP1, DXS453, and DXYS1X - in addition to analysis using RFLP markers described elsewhere. These studies localize the CMTX gene to the proximal Xq segment between PGKP1 (Xq11.2-12) and DXS72 (Xq21.1), with a combined maximum multipoint lod score of 15.3 at DXS453 ([theta] = 0). 32 refs., 3 figs., 2 tabs.« less

Challenge of handling a Charcot spinal arthropathy with a novel hybrid fibular autograft and expandable cage.

A 26-year-old man, who was paraplegic for 6 years due to a motor vehicle accident, presented to the authors' clinic following his incapacity to withstand a sitting posture, the frequent sensation of "clicks" in his back, and a complaint of back pain while in his wheelchair. On imaging, his dorsal spine showed a complete arthrodesis of the primarily fused vertebrae. However, distal to this segment, a Charcot spinal arthropathy with subluxation of T12-L1 was evident. Repair of this complex, uncommon, late complication of his paraplegia by the frequently used fusion techniques was shown to be inappropriate. A novel and elaborate surgical procedure is presented by which a complete fusion of the affected spine was secured. A left retrodiaphragmatic approach was used. Complete corpectomy of both the T-12 and L-1 vertebrae to the preserved endplates was performed. Most of the patient's fibula was resected and shaped for engrafting. The segment of the fibula was introduced into a mesh cage, before its intramedullary implantation into the T-12 and L-1 vertebrae. This 2-step procedure combined the hybrid use of a fibular autograft and an expandable mesh cage, incorporated one into the other, in an innovative intramedullary position. This intervention allowed the patient to resume his former condition as an extremely physically active patient with paraplegia. Nine years later, an asymptomatic early-stage Charcot spine was found at L5-S1, but no treatment is planned at this point.

Charcot-Marie-Tooth Neuropathy Score second version (CMTNSv2) is a validated clinical outcome measure developed for use in clinical trials to monitor disease impairment and progression in affected CMT patients. Currently, all items of CMTNSv2 have identical contribution to the total score. We used Rasch analysis to further explore psychometric properties of CMTNSv2, and in particular, category response functioning, and their weight on the overall disease progression. Weighted category responses represent a more accurate estimate of actual values measuring disease severity and therefore could potentially be used in improving the current version. © 2014 Peripheral Nerve Society.

Nietzsche, autobiography, history: mourning and Martin and John.

Champagne, J

1998-01-01

How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

Early breakdown of isolation revealed by marriage behaviour in a Ladin-speaking community (Gardena Valley, South Tyrol, Italy, 1825-1924).

PubMed

Gueresi, Paola

2012-05-01

The aim of this study was to investigate marriage behaviour from 1825 to 1924 in an Alpine valley inhabited by Ladin speakers (Gardena Valley, South Tyrol, Italy), where the particular geographic, linguistic and economic characteristics may have influenced the level of reproductive isolation. A total of 2183 marriage acts from the two main parishes of Santa Cristina and Ortisei were examined. Birth and residence endogamy, inbreeding coefficients from dispensations and from isonymy, birth place distribution of the spouses and isonymic relationships were analysed in four 25-year sub-periods. All the indicators considered point to a lower level of reproductive isolation at Ortisei, a main centre for the woodcarving industry, which appeared to be experiencing an early and effective breakdown of isolation. Marriage behaviour in the Gardena Valley between 1825 and 1924 seems to have been mostly influenced by socioeconomic factors rather than linguistic and cultural ones.

The bat community of Haiti and evidence for its long-term persistence at high elevations

Accurate accounts of both living and fossil mammal communities are critical for creating biodiversity inventories and understanding patterns of changing species diversity through time. We combined data from from14 new fossil localities with literature accounts and museum records to document the bat biodiversity of Haiti through time. We also report an assemblage of late-Holocene (1600–600 Cal BP) bat fossils from a montane cave (Trouing Jean Paul, ~1825m) in southern Haiti. The nearly 3000 chiropteran fossils from Trouing Jean Paul represent 15 species of bats including nine species endemic to the Caribbean islands. The fossil bat assemblage from Trouing Jean Paul is dominated by species still found on Hispaniola (15 of 15 species), much as with the fossil bird assemblage from the same locality (22 of 23 species). Thus, both groups of volant vertebrates demonstrate long-term resilience, at least at high elevations, to the past 16 centuries of human presence on the island. PMID:28574990

Dying devotion: discerning the association between differential mortality from scarlet fever and religious affiliation among early Edmontonians (1893-1894).

2013-06-01

Regarding the relationship between religious affiliation and patterns of differential mortality, many hold that any proxy for religion is hopelessly confounded, but that religiosity nevertheless certainly functions to benefit the health of the devout. Edmonton's scarlet fever epidemic (1893-1894) provides a counterexample to prevailing notions, in that religious affiliation is revealed as a risk-factor for this specific threat to health. Roman Catholic children were found to be at a significantly greater risk of dying from scarlet fever than were their counterparts from all other denominations combined, which is demonstrated as a direct corollary of religious affiliation.

A Search for r-Modes from 1825 to the Present

NASA Technical Reports Server (NTRS)

Wolff, Charles L.

1998-01-01

Global oscillations (r-modes) of the Sun's outer convective envelope with periods approximately 1 month and longer have been detected in several short data strings of several years duration. To test whether r-modes might persist beyond one 11 year cycle, the daily sunspot numbers from 1825 to the present were analyzed. Good evidence, but confidence level less than 3sigma, was found for most of the 14 r-modes with spherical harmonic index lambda less than or equal to 5 that can exist in the presence of solar differential rotation. The characteristic rotation rate of almost every such r-mode was detected, displaced systematically from its expected value by only 0.15%. If this probable detection is real, then most low harmonic r-modes have lifetimes exceeding one century and the rotation of the Sun's outer layers varies by less than 0.05%, except possibly at solar minimum.

We judge the worth of a scientist by the benefits he or she brings to science and society; by this measure Archer Martin was outstanding, and rightfully his contribution was recognized with a Nobel Prize. Scientific instruments and instrumental methods now come almost entirely from commercial sources and we take them for granted and often have little idea how they work. Archer Martin was of a different time when scientists would often devise their own new instruments, which usually they fully understood, and then they would use them to explore the world. The chromatographic methods and instruments Martin devised were at least as crucial in the genesis and development of molecular biology as were those from X-ray crystallography. Liquid partition chromatography, especially in its two-dimensional paper form, revealed the amino acid composition of proteins and the nucleic acid composition of DNA and RNA with a rapid and elegant facility. Gas chromatography (GC) enabled the accurate and rapid analysis of lips, which previously had been painfully slow and little more than a greasy sticky confusion of beaker chemistry. Martin's instruments enabled progress in the sciences ranging from geophysics to biology , and without im we might have waited decades before another equivalent genius appeared. More than this, the environmental awareness that Rachel Carson gave us would never had solidified as it did without the evidence of global change measured by GC. This instrumental method provided accurate evidence about the ubiquity of pesticides and pollutants and later made us aware of the growing accumulation in the atmosphere of chlorinated fluorocarbons, nitrous oxide and other ozone-depleting chemicals. If all this were not enough to glorify Martin's partition chromatography, there is the undoubted fact that its simplicity, economy and exquisite resolving power transformed the chemical industry and made possible so many of the conveniences we now take for granted.

2017-01-01

Diabetic Charcot neuroarthropathy (DCN) of the foot and ankle is a challenging disease with regard to clinical presentation, pathogenesis, and prognosis. Its surgical management is equally difficult to interpret based on the wide array of options available. In the presence of an ulceration or concomitant osteomyelitis, internal fixation by means of screws, plates, or intramedullary nailing needs to be avoided when feasible. External fixation becomes a great surgical tool when managing DCN with concomitant osteomyelitis. This article describes internal and external fixation methods along with available literature to enlighten surgeons faced with treating this complex condition. Copyright © 2016 Elsevier Inc.

2017-10-01

Particle physicist Martin Lewis Perl was recognized worldwide for his discovery of the τ (tau) lepton. For that achievement he received the 1982 Wolf Prize and shared the 1995 Nobel Prize in Physics. He was also a Fellow of the American Physical Society and a member of the National Academy of Sciences (elected 1981). Martin's distinctive approach to scientific investigation had its origins in his upbringing and in the influence of I. I. Rabi, his graduate advisor at Columbia University. After coming to Stanford University in 1963, Martin sought to understand why there should be two and only two families of leptons: the electron and its associated neutrino; and the muon and the muon neutrino. His discovery of the τ provided evidence for a third family of fundamental leptons. The bottom quark was discovered shortly afterward at the Fermi National Accelerator Laboratory, providing evidence for a third family of quarks. Direct evidence for the τ neutrino came later, thereby completing the third lepton generation, while the discovery of the top quark in 1995 completed the third generation of quarks. These achievements established leptons and quarks as fundamental constituents of matter and, along with the fundamental forces, provided the experimental basis of the "Standard Model," our picture of how all matter is made up and how its components interact. Why there are three and only three families of leptons and quarks remains an unsolved mystery to this day.

2015-10-01

This report describes the case of a 74-year-old man who had been diagnosed with Charcot-Marie-Tooth disease as a child. Because the patient had serious motor and sensory neuropathy associated with his disease, special anesthetic and surgical recommendations had to be considered before he underwent general anesthesia to repair his mandibular fracture. Repair of the mandible was performed under general anesthesia with a nasal endotracheal tube and the use of the nondepolarizing muscle relaxant rocuronium. Open reduction and internal fixation through extraoral approaches were used to fixate the displaced right subcondylar and symphyseal fractures. A closed reduction approach using maxillary fixation screws and a mandibular arch bar with light elastic guidance was used to treat a nondisplaced fracture of the left mandibular ramus. Rigid fixation allowed for avoidance of a period of intermaxillary fixation. General anesthesia and muscle relaxant were administered without complication. Treatment of bilateral mandibular fractures with combined open and closed approaches resulted in restoration of premorbid occlusion and masticatory function. Repair of mandibular fractures under general anesthesia appears to be a safe procedure in patients with Charcot-Marie-Tooth disease when appropriate anesthetic and surgical methods are used.

Charcot foot (CF) is a rare complication of Type 2 diabetes (T2D). We assessed circulating miRNAs in 17 patients with T2D and acute CF (G1), 17 patients with T2D (G2) and equivalent neuropathy and 17 patients with T2D without neuropathy (G3) using the high-throughput miRNA expression profiling. 51 significantly deregulated miRNAs were identified in G1 versus G2, 37 in G1 versus G3 and 64 in G2 versus G3. Furthermore, we demonstrated that 16 miRNAs differentially expressed between G1 versus G2 could be involved in osteoclastic differentiation. Among them, eight are key factors involved in CF pathophysiology. Our data reveal that CF patients exhibit an altered expression profile of circulating miRNAs.

The aim of the present study was to investigate the subclinical involvement of the central nervous system (CNS) in an X-linked Charcot-Marie-Toth (CMTX) family. Seven subjects, all members of one family with a C.462T > G connexin 32 (Cx32) mutation were investigated by Blink reflex, Somatosensory evoked potentials (SEP) and Transcranial magnetic stimulation (TMS). There were five clinically symptomatic for CMT neuropathy (four male and one female) and two asymptomatic (female) subjects. Subclinical CNS involvement was observed in all, symptomatic and asymptomatic subjects. This is the largest CMTX neuropathy family investigated for CNS involvement. Electrophysiological involvement of the CNS in every examined member of this family was observed, raising the question of a more systematic involvement of the CNS in CMTX disease.

Charcot neuroarthropathy is a low-incidence complication of diabetic foot and is associated with ankle and hind foot deformity. Patients who have not developed deep ulcers are managed with offloading and supportive bracing or orthopedic arthrodesis. In patients who have developed ulcers and severe ankle instability and deformity, below-the-knee amputation is often indicated, especially when deformity and cutaneous involvement result in osteomyelitis. Ischemic association has not been described but can be present as a part of peripheral arterial disease in the diabetic population. In this extreme and advanced stage of combined neuroischemic diabetic foot disease, revascularization strategies can support surgical andmore » orthopedic therapy, thus preventing osteomyelitis and leading to limb and foot salvage.« less

Martin Schwarzschild, the ASP Bruce Medalist for 1965, died on 10 April 1997. A refugee from Hitler's Germany who firmly embraced his adopted country, Schwarzschild not only solved a number of fundamental problems in stellar structure and evolution but also taught the rest of the astronomical community how to do so with his 1958 text, Structure and Evolution of the Stars. At about the time of his 1979 retirement, he turned to a completely different question of how to model spheroidal galaxies self-consistently and sent another generation of students and collaborators forward toward the still somewhat distant solution. It is impossible for anyone who ever interacted with Schwarzschild to remain entirely solemn when remembering him. (SECTION: Obituary)

ACQUIRED PES CAVUS IN CHARCOT-MARIE-TOOTH DISEASE.

PubMed

Maranho, Daniel Augusto; Volpon, José Batista

2009-01-01

Hereditary motor and sensory neuropathies, especially Charcot-Marie-Tooth disease, are frequently expressed with an acquired cavusvarus foot which is characterized by a fixed increase of the plantar arch and hindfoot inversion. Diagnosis of the underlying condition achieved through careful patient assessment and local evaluations is the keystone for decision-making about the adequate treatment. The cavus may present as an isolated deformity of the forefoot, hindfoot or it may be a combination of both locations. Related deformities, mainly the varus and toe clawing require appropriate evaluation; clinical characteristics such as severity of the deformity, impairment of the muscular power, flexibility and patient's age are important characteristics in the treatment decision. Conservative treatment of the cavusvarus foot with physiotherapy, insoles and shoe modifications are reserved to young patients and mild deformities. However, there is a tendency of the deformity to become more severe over time because of the progressive feature of the underlying neurological condition. So, the surgical treatment by using classical techniques is performed in early stages. Most importantly is the identification of the primary and main components of each deformity to properly correct them, if possible. Muscular transfers are used to treat the dynamic unbalance, retracted structures should be either divided or lengthened and localized osteotomies should be preferred over arthrodeses, which are reserved for stiff and severely deformed feet in adults.

A sea-beam, seismic, magnetic, and gravimetric survey was conducted with the R/V Jean-Charcot in three key regions off the Taiwan-Philippine festoon in the western Pacific: (1) Ryukyu active margin and its junction with Taiwan; (2) northern part of the Manila Trench and its junction with the Taiwan tectonic prism; and (3) southern termination of Manila Trench in front of Mindoro Island. Transitions between active subduction along the Manila Trench and collision of Taiwan and Mindoro, and relations between active subduction and extension in the Okinawa-Ryukyu and the northeastern Taiwan systems are particularly studied.

Pierre Jean Georges Cabanis (1757-1808): an early nineteenth century source for the concept of nervous energy in European behavioral neurosciences.

PubMed

Turgeon, Y; Whitaker, H A

2000-01-01

The nineteenth century witnessed many advances in neuroscientific concepts. Among the notable are Charles Bell's (1774-1842) and François Magendie's (1783-1855) identification of sensory and motor pathways, Thomas Henry Huxley's (1825-1895) elaboration of evolutionary theory in the context of comparative neuroanatomy, and Emile Du Bois-Reymond's (1818-1896) and Hermann von Helmholtz's (1821-1894) work in experimental neurophysiology and on the concept of nervous energy. In Germany, the idea that the nervous system consisted of two elements, one that generated nervous energy and another that conducted it throughout the body, had wide currency in mid-nineteenth century. In France, Pierre Jean Georges Cabanis (1757-1808), physician, philosopher, and one of the founders of modern psychophysiology, argued that the brain is the part of the body in which electricity is stored. In his Rapports du Physique et du Moral de l'Homme, published between 1796 and 1802 (translated into German under the title Verhältnis der Seele zum Körper (1808)), Cabanis proposed new ideas on brain function, on the brain's own sensibility, on the concept of will, and on the chemical basis of nervous activity. In the Rapports Cabanis proposed a theory of how brain and nerves relate to thought and behavior. Foreshadowing later developments in neuropsychology, he suggested that different parts of the nervous system have separate functions. Despite the fact that Cabanis had many interesting ideas about brain function, he has been largely ignored by historians of neuroscience; e. g., he is mentioned briefly in Clark and Jacyna (1989), in only two footnotes in Neuburger (1897/1981), and not at all in Finger (1994). Cabanis's far-reaching theory of how the brain works helped shape understanding of the general notion of nervous energy in nineteenth-century European neuroscience.

Identification of the skeletal remains of Martin Bormann by mtDNA analysis.

2001-01-01

Contrary to statements of an eye-witness who reported that Martin Bormann, the second most powerful man in the Third Reich, died on 2 May 1945 in Berlin, rumours persisted over the years that he had escaped from Germany after World War II. In 1972, skeletal remains were found during construction work, and by investigating the teeth and the bones experts concluded that they were from Bormann. Nevertheless, new rumours arose and in order to end this speculation we were commissioned to identify the skeletal remains by mitochondrial DNA analysis. The comparison of the sequence of HV1 and HV2 from the skeletal remains and a living maternal relative of Martin Bormann revealed no differences and this sequence was not found in 1,500 Caucasoid reference sequences. Based on this investigation, we support the hypothesis that the skeletal remains are those of Martin Bormann.

PubMed

Chauvin, Frédéric; Fischer, Louis-Paul

2010-01-01

René Nicolas Dufriche Desgenettes (1762-1837) became famous through two historical events: the first and most famous one is where he proved his courage by inoculating himself with the plague during the Syrian campaign in 1799; the second one, rarely represented in paintings, happened during the Russian retreat in 1812 when he was freed thanks to his reputation. Two wide fresco paintings facing each other in the hall of Desgenettes, a hospital built during World War Two, are witnesses of these two major events. Jean Coquet (1907-1990), a decorator, painter and glassblower, who worked at the Beaux-Arts School of Lyon, first as a decoration teacher than as its director, painted these two works of art. In 1946, he inserted them into an ornamental group constituted of ironworks, furniture, stained glass and ceramics. Two paintings from Antoine-Jean Gros (1771-1835) inspired these works: Bonaparte visiting the plague-stricken of Jaffa (1804) and Napoleon on the battlefield of Eylau (1808). With their academic composition and daring stylization those two frescoes represent in a modern and original way Desgenettes' life style, an archetype of what the military doctor is.

[Education of surgeons at the Medical School of the University of Pest between 1825 and 1848].

PubMed

Simon, Katalin

2009-01-01

From the 1820's a great number of surgeons attended the Faculty of Medicine in Pest. The increasing number of the students was resulted by several circumstances. After the Napoleonic wars peregrination from Hapsburg lands was prohibited. The Faculty of Medicine in Pest however offerred a diploma for its students valid for the whole territory of the Hapsburg Empire. The lectures were held in Hungarian or German, in contrary to the exclusively Latin lectures for medical students. A shorter preliminary education was needed. After three years the student could get his degree Chirurgiae Magister or Chirurgus civilis--the length of studies depended on the pleriminary studies of the surgeon. The Faculty started only two courses, so the surgeons mostly repeated the second or both courses. Although these degrees proved to be inferior to the titles Doctor Medicinae or Doctor Chirurgiae, many students wanted to get it. In the beginning of this period, in 1825/1825 117 persons attended the first semesters of the German, and 59 of the Hungarian course. This growth reached its peak in the years of the cholera. In 1832/1833 255 person matriculated to the first class of the German and 148 to the Hungarian course. This new contagion damaged not only human lifes, but the popularity of the surgical education as well. The number of students began slowly decrease. Another reason for this decrease was the new possibility for peregrination from the 1830's. In 1846/1847 48 persons matriculated to the first German course, and 49 to the Hungarian, while in the second one their number was only 10 and 20. As we can see, the German course was more popular, here came students from the other parts of the Hapsburg Empire, especially Jews: from Moravia (160; 110 of them was Jew), Bohemia (134) or Galicia (178; 124 of them was Jew). Between 1825 and 1846 2618 surgeons matriculated to the Faculty of Pest, many of them however left it with or without doing their exams. 1854 students took every exam

Shake the Disease. Georges Marinesco, Paul Blocq and the Pathogenesis of Parkinsonism, 1893

PubMed Central

Hostiuc, Sorin; Drima, Eduard; Buda, Octavian

2016-01-01

James Parkinson, in his “Essay on the Shaking Palsy” from 1817 described for the first time the disease that later on carried his name. Its anatomical substrate remained controversial for over 100 years. The first case that suggested the association between Parkinson’s disease and substantia nigra was published in 1893 Blocq and Marinesco, two scientists who worked at Salpêtrière. The article described a 38 years-old man, with tuberculosis, who was admitted to the Charcot’s neurological ward because he also showed signs of unilateral Parkinsonism. During the autopsy, the investigators found a tubercle that destroyed the right substantia nigra. As the patient had overactive reflexes on the left side and the symptomatology matched exactly the localization of the tumor, Blocq and Marinesco suggested the Parkinsonism to be more likely a complication of tuberculosis and not an incidental finding. In this article, we will discuss the contribution of these two authors to the elucidation of the pathology of Parkinson’s disease, and highlight how even a single case report may play an essential role in the development of knowledge in biomedical sciences.

2002-01-01

The first formal attempt at revising Bowen theory within the marriage and family therapy literature is represented in the work of Knudson-Martin (1994). Claiming that several of the theory's concepts are defined at odds with female development, Knudson-Martin (1994) reconceptualizes and expands Bowen theory to rectify these perceived shortcomings. In turn, we address several fundamental concerns with Knudson-Martin's critique and revision of Bowen theory. An alternative representation of Bowen Theory, as well as its relationship to feminist thought, is put forth. Suggestions for the field's future relationship to Bowen theory are also discussed.

Hand involvement in children with Charcot-Marie-Tooth disease type 1A.

2008-12-01

Charcot-Marie-Tooth disease type 1A (CMT1A), a demyelinating neuropathy characterised by progressive length-dependent muscle weakness and atrophy, is thought to affect the foot and leg first followed some time later by hand weakness and dysfunction. We aimed to characterise hand strength, function and disease-related symptoms in children with CMT1A. Intrinsic and extrinsic hand strength was measured by hand-held dynamometry, function by nine-hole peg test, and disease-related symptoms by interview and examination in 84 affected children aged 2-16 years. Hand weakness and dysfunction was present from the earliest stages of the disease. While hand strength and function measures tended to increase with age throughout childhood, at no point did they reach normal values. Day-to-day hand problems such as poor handwriting, weakness, pain and sensory symptoms also worsened with age. The hand is affected at all ages in children with CMT1A, but may be under-recognised in its early stages, potentially delaying therapy.

The effect of an interval exercise training (ITE) program on heart rate variability (HRV) was studied in 8 patients with Charcot-Marie-Tooth (CMT) disease and 8 healthy controls. At baseline, all subjects underwent ambulatory 24-hour Holter electrocardiographic (ECG) monitoring to evaluate HRV. HRV analysis was repeated on CMT patients after they completed a 24-week ITE program on a cycle ergometer. Before exercise, all HRV indices were lower in patients compared with controls, and the difference reached statistical significance for pNN50 (percent of differences between adjacent R-R intervals exceeding 50 ms). After ITE, time- and frequency-domain indices were significantly improved, particularly at night (+8% mean R-R interval, +95% pNN50, 52% reduction in low/high-frequency ratio). We observed significant increases in some of the time and frequency parameters, and values sometimes exceeded those of controls at baseline. Our results suggest that ITE improves HRV modulation in CMT patients by enhancing parasympathetic activity. Copyright © 2011 Wiley Periodicals, Inc.

Hospitals of Rome in the Early Nineteenth Century: The Apostolic Visit of 1825.

PubMed

Duffin, Jacalyn

2016-01-01

Pope Leo XII marked the 1825 Jubilee by visiting the hospitals of Rome. Italy was recovering from the French invasion that had disrupted social and religious structures. The Visitors investigated conditions, and recommended changes. By 1826, eight large hospitals were ordered to unite, but, three years later, the order was rescinded. Based on the Visit's mostly unexamined records in the Vatican Secret Archives, hospital registers, and minutes of the governing council held in the Archivio di Stato di Roma, this paper reconstructs the network of Rome's hospitals in the early 19 th century. It also compares Roman hospitals to its Parisian counterparts, especially with respect to governance and education. Finally, it examines the merger as an early example of a practice that remains vibrant (if controversial) today.

Re-examining Distal Facies of the Grand Bay Ignimbrite at Fond St. Jean, Dominica

NASA Astrophysics Data System (ADS)

Ebner, N.; Frey, H. M.; Wirth, K. R.; Waters, L. E.; Manon, M. R. F.

2017-12-01

The Grand Bay ignimbrite in southern Dominica is a relatively young (43 ± 13 ka by U-Th of zircon), voluminous (0-.5-1 km3 on-land) and laterally extensive pyroclastic flow deposit spanning over 20 km2 that has been associated with the Micotrin volcanic center or Plat Pays complex. The Grand Bay ignimbrite typically occurs as a massive valley fill facies, approximately 9-14 meters thick, exposed on the southern coastal road, rich in white-light gray, relatively crystal rich (25-31%) andesitic (62-63.5 wt% SiO2, 16.7 wt% Al2O3, 6.5 wt % Fe2O3) pumice, whose mineral assemblage is dominated by plagioclase (22-25%), orthopyroxene (3-4%), and clinopyroxene (1-1.5%), in an unconsolidated gray ashy matrix. In the literature, distal facies of the Grand Bay ignimbrite have been proposed at Fond St. Jean (FSJ), but this supposition has recently been called into question. The 9 m thick stratified Fond St. Jean ignimbrite, (38,890 k.a. ± 600 B.P. by14C), is weathered yellow orange and overlies a 4 m thick lithified beach deposit on a sharp contact. Andesitic pumice clasts (60.5-64.5 wt% SiO2, 18 wt% Al2O3, 5.5 wt % Fe2O3) from the base of the FSJ ignimbrite contain similar mineral assemblages to Grand Bay clasts, however, FSJ pumices are relatively less crystal-rich (16-19%), contain significantly less plagioclase (13-16%), opx (1.0-1.5%), cpx (0.1 - 0.6%), and, most strikingly, up to 1% hornblende, which was not present in any Grand Bay samples. The lowermost three meters of the FSJ ignimbrite sequence is composed of meter thick sections of clast (5-7 cm pumice and ≤1 cm lithics) supported beds (70 cm), grading upwards into 30 cm of ash laminations and small pumice clasts (1-3 cm). Following a 40 cm bed of massive ash containing 1-3 cm clasts of pumice, the initial sequence repeats itself for 5 meters, with 30-40 cm lithic blocks in the uppermost unit.

On the Anomalously Large Extension of the Pulsar Wind Nebula HESS J1825-137

NASA Astrophysics Data System (ADS)

Khangulyan, Dmitry; Koldoba, Alexander V.; Ustyugova, Galina V.; Bogovalov, Sergey V.; Aharonian, Felix

2018-06-01

The very high energy gamma-ray emission reported from a number of pulsar wind nebulae (PWNe) is naturally explained by the inverse Compton scattering of multi-TeV electrons. However, the physical dimensions of some gamma-ray-emitting PWNe significantly exceed the scales anticipated by the standard hydrodynamical paradigm of PWN formation. The most “disturbing” case in this regard is HESS J1825-137, which extends to distances of r ≈ 70 pc from the central pulsar PSR J1826‑1334. If the gamma-ray emission is indeed produced inside the PWN, but not by electrons that escaped the nebula and diffuse in the interstellar medium (ISM), the formation of such an anomalously extended plerion could be realized, in a diluted environment with the hydrogen number density {n}{{ISM}}≤slant {10}-2 {cm}}-3. In this paper, we explore an alternative scenario assuming that the pulsar responsible for the formation of the nebula initially had a very short rotation period. In this case, the sizes of both the PWN and the surrounding supernova remnant depend on the initial pulsar period, the braking index, and the ISM density. To check the feasibility of this scenario, we study the parameter space that would reproduce the size of HESS J1825-137. We show that this demand can be achieved if the braking index is small, n≤slant 2, and the pulsar birth period is short, {P}{{b}}≃ 1 {ms}. This scenario can reproduce the wind termination position, which is expected at {R}{{TS}}≃ 0.03 {pc}, only in a dense environment with {n}{{ISM}}≥slant 1 {cm}}-3. The requirement of the dense surrounding gas is supported by the presence of molecular clouds found in the source vicinity.

Gravity gradiometry developments at Lockheed Martin

NASA Astrophysics Data System (ADS)

Difrancesco, D.

2003-04-01

Lockheed Martin has developed and fielded multiple configurations of the rotating accelerometer gravity gradiometer instrument. Applications for both static and moving-base measurements have been demonstrated for a variety of scenarios, including vehicle navigation, hydrocarbon exploration, mineral exploration, reservoir monitoring, underground void detection and treaty monitoring and compliance. The most recent systems built by Lockheed Martin extend the performance range of the early 4-accelerometer gradiometers by adding a second complement of four accelerometers. This achieves the benefit of lower instrument noise and improved frequency response (wider bandwidth) for stringent application scenarios. A summary of the gradiometer development history, functional concepts, instrument and system operation, and demonstrated performance will be presented. Development Background The U. S. Air Force Geophysics Laboratory (AFGL; now AFRL) instituted a program in 1982 to develop and field a moving base gradiometer system that could be used both on land and in the air. The result was the Gravity Gradiometer Survey System (GGSS) which first demonstrated the ability to make airborne gravity gradient measurements in 1987 (Jekeli, 1988). At the same time, the U.S. Navy began development of the Gravity Sensors System (GSS) for use on the Fleet Ballistic Submarine Trident II navigation subsystem. This military background paved the way for commercial uses of gravity gradiometry. Both the GSS and GGSS employed a first generation gravity gradiometer instrument (GGI), which was comprised of four accelerometers mounted on a rotating disk. The details of the GGI operation are further described in the work by Gerber and Hofmeyer (Gerber, 1978 and Hofmeyer, 1994). Recent Advancements in Gradiometer Instrumentation With the instrumentation experience gained through such programs as GSS and GGSS, Lockheed Martin embarked upon an ambitious effort in the early 1990's to further improve the

An investigation of the properties of linear stability is conducted for a system consisting of particles having mass m and charge q, interacting through the gravitational and electrostatic force (Jeans instability). However, in light of recent works showing that dust particles in a plasma can have a Lennard-Jones-like shielding potential, a new set of equations has been derived, where the electrostatic interaction among the dust particles is Lennard-Jones-like instead of Coulomb-like. A new condition for the gravitational instability is derived, showing a broader spectrum of unstable modes with faster growth rates.

The early evolution of Jean Piaget's clinical method.

PubMed

Mayer, Susan Jean

2005-11-01

This article analyzes the early evolution of Jean Piaget's renowned "clinical method" in order to investigate the method's strikingly original and generative character. Throughout his 1st decade in the field, Piaget frequently discussed and justified the many different approaches to data collection he used. Analysis of his methodological progression during this period reveals that Piaget's determination to access the genuine convictions of children eventually led him to combine 3 distinct traditions in which he had been trained-naturalistic observation, psychometrics, and the psychiatric clinical examination. It was in this amalgam, first evident in his 4th text, that Piaget discovered the clinical dynamic that would drive the classic experiments for which he is most well known.

Sensory loss and ulcero-mutilating features have been observed in hereditary sensory neuropathy type I and in hereditary motor and sensory neuropathy type IIB, also referred as Charcot-Marie-Tooth disease type 2B. To date two loci associated with ulcero-mutilating neuropathy have been described: CMT2B at 3q13-q22 and HSN I at 9q22.1-q22.3. We performed linkage analysis with chromosomal markers representing the hereditary sensory neuropathy type I and Charcot-Marie-Tooth disease type 2B loci on an Italian family with a severe distal sensory loss leading to an ulcero-mutilating peripheral neuropathy. Negative likelihood-of-odds scores excluded any evidence of linkage to both chromosome 3q13 and chromosome 9q22 markers, confirming the genetic heterogeneity of this clinical entity and the presence of a third locus responsible for ulcero-mutilating neuropathies.

On the centenary of Charcot: hysteria, suggestibility and hypnosis.

PubMed

Chertok, L

1984-06-01

In studying hysteria by means of hypnosis, Charcot placed emphasis on the psychological aetiology of the neuroses. Among his pupils, Freud alone grasped this epistemological turning-point, from which he made his great discoveries. But hysteria and hypnosis still remain today largely unknown. We have not yet elucidated the 'mysterious leap' between the psychological and the somatic for the former, and between the relational and the instrumental for the latter. While psychoanalysts have constantly concerned themselves with hysteria, they have shown a lack of interest in hypnosis after Freud abandoned its practice. According to Freud, thanks to transference, affect would be controlled by cognition, a viewpoint eminently suited to satisfy his rationalistic outlook. Affect, however, remains an unknown realm. The affective relationship has, at all events, acquired an ever-increasing importance in psychoanalysis during the last few years, with the emphasis on the early mother-child relationship. The 'affective locus' remains the basic, as well as the most obscure, element in the hypno-suggestive relationship. The behaviourist approach, which quantifies the 'vertical' dimension in depth, is a limited one. The study of the 'horizontal' dimension of subjective experience represents a new line of research, which may make it possible to distinguish different forms of hypnosis. The understanding of hypno-suggestion may throw light on psychoanalysis, psychotherapy, and the human sciences in general.

Jeans Instability of the Self-Gravitating Viscoelastic Ferromagnetic Cylinder with Axial Nonuniform Rotation and Magnetic Field

NASA Astrophysics Data System (ADS)

Dhiman, Joginder Singh; Sharma, Rajni

2017-12-01

The effects of nonuniform rotation and magnetic field on the instability of a self gravitating infinitely extending axisymmetric cylinder of viscoelastic ferromagnetic medium have been studied using the Generalised Hydrodynamic (GH) model. The non-uniform magnetic field and rotation are acting along the axial direction of the cylinder and the propagation of the wave is considered along the radial direction, while the ferrofluid magnetization is taken collinear with the magnetic field. A general dispersion relation representing magnetization, magnetic permeability and viscoelastic relaxation time parameters is obtained using the normal mode analysis method in the linearized perturbation equation system. Jeans criteria which represent the onset of instability of self gravitating medium are obtained under the limits; when the medium behaves like a viscous liquid (strongly coupled limit) and a Newtonian liquid (weakly coupled limit). The effects of various parameters on the Jeans instability criteria and on the growth rate of self gravitating viscoelastic ferromagnetic medium have been discussed. It is found that the magnetic polarizability due to ferromagnetization of medium marginalizes the effect of non-uniform magnetic field on the Jeans instability, whereas the viscoelasticity of the medium has the usual stabilizing effect on the instability of the system. Further, it is found that the cylindrical geometry is more stable than the Cartesian one. The variation of growth rate against the wave number and radial distance has been depicted graphically.

Mutational studies in X-linked Charcot-Marie-Tooth disease (CMTX)

DOE Office of Scientific and Technical Information (OSTI.GOV)

1994-09-01

Charcot-Marie-Tooth disease, also known as hereditary motor and sensory neuropathy (HMSN), is a heterogeneous group of slowly progressive disorders of the peripheral nerve. X-linked CMT (CMTX) is characterized by slow motor nerve conduction velocities in affected males and the presence of mildly affected or normal carrier females with intermediate or normal nerve conduction velocities. CMTX, which has an incidence of 3.1 per 100,000 and accounts for approximately 10% of CMT cases, has been mapped to Xq13. One of the genes lying in this region, connexin 32, has been found to contain alterations in individuals affected with X-linked CMT. We havemore » identified our X-linked families from dominant type 1 CMT families using the clinical criteria given above. These families were screened for point mutations in connexin 32. We have identified three missense mutations, a G{r_arrow}A transition at amino acid 35 (valine to methionine), a C{r_arrow}G transition at amino acid 158 (proline to alanine) and a T{r_arrow}A transition at amino acid 182 (serine to threonine). Another family showed a 18 bp deletion, which removed the amino acid 111 to 116 inclusive (histidine, glycine, aspartic acid, proline, leucine, histidine).« less

Gravity or turbulence? - III. Evidence of pure thermal Jeans fragmentation at ˜0.1 pc scale

2015-11-01

We combine previously published interferometric and single-dish data of relatively nearby massive dense cores that are actively forming stars to test whether their `fragmentation level' is controlled by turbulent or thermal support. We find no clear correlation between the fragmentation level and velocity dispersion, nor between the observed number of fragments and the number of fragments expected when the gravitationally unstable mass is calculated including various prescriptions for `turbulent support'. On the other hand, the best correlation is found for the case of pure thermal Jeans fragmentation, for which we infer a core formation efficiency around 13 per cent, consistent with previous works. We conclude that the dominant factor determining the fragmentation level of star-forming massive dense cores at 0.1 pc scale seems to be thermal Jeans fragmentation.

The news about the discovery of the anaesthetic properties of ether swept rapidly from America to Europe. The first informations concerning this topic reached England in late fall of 1846 and after that came to France and especially Paris. The German physician Aloys Martin from Munich who was living in Paris at that time was largely responsible for conveying the news about these new findings in medical science to the German-speaking nations. Controversial discussions concerning the anaesthetic properties of ether developed among the members of various scientific circles right after the news from America had reached the city--and many members of the "Verein Deutscher Aerzte in Paris" (Association of German Physicians in Paris) took part in them, Martin then was one of the club's most active members and repeatedly reported on the new method as a correspondent for the widely read "Augsburger Allgemeine Zeitung": Documents discovered recently at the archives of the "Leopoldinisch-Carolinischen Akademie" of Halle provide an interesting insight into this association, whose members tried to find out more about the anaesthetic properties and side effects of ether carrying out a series of well appreciated self-experiments in the spring of 1847. The following text reports on the history of the "Verein Deutscher Aerzte in Paris" which has largely fallen into oblivion and emphasizes the importance of Aloys Martin whose name is strongly attached to the spread of the use of ether throughout the German-speaking countries.

1999-11-01

This article is a thumbnail sketch of the life and times of Martin Van Butchell (1735-1814), an eccentric, "kook" advertising dentist of Old London. Van Butchell earned these descriptive labels by displaying an unorthodox lifestyle, an outrageous personal appearance and outlandish, extreme and socially unacceptable personal and professional behaviors. While the general populace seemed to be fascinated by his strange ways, dentists and physicians were generally alienated by them. Nevertheless, he was considered a good dentist for his time, and he was extremely popular with his patients. Martin practiced dentistry for 23 years, and he practiced medicine as well, specializing in the treatment of ruptures and anal fistulas. Van Butchell interacted greatly with both John and William Hunter, who became two of the most famous and talented physicians, surgeons, anatomists and biologists of all time. When his first wife, Mary died, Martin arranged for her body to be embalmed and publicly displayed in his dental office for advertising purposes. Her preserved body was shown at the Museum of the Royal College of Surgeons (London), until it was destroyed by a German fire bomb in May, 1941. Mary's remains were on public display for a total of 166 years.

The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to enable significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that was to have improved U.S. economic competitiveness. The X-33 was a wedged-shaped subscale technology demonstrator prototype of a potential future Reusable Launch Vehicle (RLV) that Lockheed Martin had dubbed VentureStar. The company had hoped to develop VentureStar early this century. Through demonstration flight and ground research, NASA's X-33 program was to have provided the information needed for industry representatives such as Lockheed Martin to decide whether to proceed with the development of a full-scale, commercial RLV program. A full-scale, single-stage-to-orbit RLV was to have dramatically increased reliability and lowered the costs of putting a pound of payload into space, from the current figure of $10,000 to $1,000. Reducing the cost associated with transporting payloads in Low Earth Orbit (LEO) by using a commercial RLV was to have created new opportunities for space access and significantly improve U.S. economic competitiveness in the world-wide launch marketplace. NASA expected to be a customer, not the operator, of the commercial RLV. The X-33 design was based on a lifting body shape with two revolutionary 'linear aerospike' rocket engines and a rugged metallic thermal protection system. The vehicle also had lightweight components and fuel tanks built to conform to the vehicle

Potential skin involvement in ALS: revisiting Charcot's observation - a review of skin abnormalities in ALS.

PubMed

Paré, Bastien; Gros-Louis, François

2017-07-26

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting motor neurons of the brain and spinal cord, leading to progressive paralysis and death. Interestingly, many skin changes have been reported in ALS patients, but never as yet fully explained. These observations could be due to the common embryonic origin of the skin and neural tissue known as the ectodermal germ layer. Following the first observation in ALS patients' skin by Dr Charcot in the 19th century, in the absence of bedsores unlike other bedridden patients, other morphological and molecular changes have been observed. Thus, the skin could be of interest in the study of ALS and other neurodegenerative diseases. This review summarizes skin changes reported in the literature over the years and discusses about a novel in vitro ALS tissue-engineered skin model, derived from patients, for the study of ALS.

Estimated Flying Qualities of the Martin Model 202 Airplane

Weil, Joseph; Spear, Margaret

1947-01-01

The flying qualities of the Martin model 202 airplane have been estimated chiefly from the results of tests of an 0.0875-scale complete model with power made in the Wright Brothers tunnel at the Massachusetts Institute of Technology and from partial span wing and isolated vertical tail tests made in the Georgia Tech Nine-Foot Tunnel. These estimated handling qualities have been compared with existing Army-Navy and CAA requirements for stability and control. The results of the analysis indicate that the Martin model 202 airplane will possess satisfactory handling qualities in all respects except possibly in the following: The amount of elevator control available for landing or maneuvering in the landing condition is either marginal or insufficient when using the adjustable stabilizer linked to the flaps . Moreover, indications are that the longitudinal trim changes will be neither large nor appreciably worse with a fixed stabilizer than with the contemplated arrangement utilizing the adjustable stabilizer in an attempt to reduce the magnitude of the trim changes caused by flap deflection.

Three Decades Investigating Humor and Laughter: An Interview With Professor Rod Martin

Martin, Rod; Kuiper, Nicholas A.

2016-01-01

Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin’s research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin’s earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin’s subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin’s comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

Charcot-Marie-Tooth disease (CMT) is a peripheral neuromuscular disorder in which axonal degeneration causes progressive loss of motor and sensory nerve function. The loss of motor nerve function leads to distal muscle weakness and atrophy, resulting in gait problems and difficulties with walking, running, and balance. A mutation in the cytoplasmic dynein heavy chain (DHC) gene was discovered to cause an autosomal dominant form of the disease designated Charcot-Marie-Tooth type 2 O disease (CMT2O) in 2011. The mutation is a single amino acid change of histidine into arginine at amino acid 306 (H306R) in DHC. In order to understand the onset and progression of CMT2, we generated a knock-in mouse carrying the corresponding CMT2O mutation (H304R/+). We examined H304R/+ mouse cohorts in a 12-month longitudinal study of grip strength, tail suspension, and rotarod assays. H304R/+ mice displayed distal muscle weakness and loss of motor coordination phenotypes consistent with those of individuals with CMT2. Analysis of the gastrocnemius of H304R/+ male mice showed prominent defects in neuromuscular junction (NMJ) morphology including reduced size, branching, and complexity. Based on these results, the H304R/+ mouse will be an important model for uncovering functions of dynein in complex organisms, especially related to CMT onset and progression.

Osteohistometric studies were performed in 15 female and 15 male cadavers aged 18-25. Condyloid process and right and left acetabulum of the temporo-mandibular joint have been studied. Density has been investigated using monitor screen linked with microscope (magnification 80x). Density in the spongy part of the condyloid process was 26.67-26.77%; in the subchondrial layer--72.13-72.72%, and in the acetabular wall 75.03-75.91%. Microscopic structure of the bones of the temporo-mandibular joint revealed no differences when compared with images of compact and cancellous bone shown in the histology textbooks. Sex and the side of the body had no influence on microscopic image and proportional bone density. Isles of chondrocytes in the trabeculae of the spongy structure of the condyloid process were found in 4 cases and isles of the condensed bone resembling the compact pattern in 7 cases.

P0 glycoprotein is an abundant product of terminal differentiation in myelinating Schwann cells. The mutant P0S63del causes Charcot-Marie-Tooth 1B neuropathy in humans, and a very similar demyelinating neuropathy in transgenic mice. P0S63del is retained in the endoplasmic reticulum of Schwann cells, where it promotes unfolded protein stress and elicits an unfolded protein response (UPR) associated with translational attenuation. Ablation of Chop, a UPR mediator, from S63del mice completely rescues their motor deficit and reduces active demyelination by half. Here, we show that Gadd34 is a detrimental effector of CHOP that reactivates translation too aggressively in myelinating Schwann cells. Genetic or pharmacological limitation of Gadd34 function moderates translational reactivation, improves myelination in S63del nerves, and reduces accumulation of P0S63del in the ER. Resetting translational homeostasis may provide a therapeutic strategy in tissues impaired by misfolded proteins that are synthesized during terminal differentiation.

There are no accepted methods to grade bone marrow oedema (BMO) and fracture on magnetic resonance imaging (MRI) scans in Charcot osteoarthropathy. The aim was to devise semiquantitative BMO and fracture scores on foot and ankle MRI scans in diabetic patients with active osteoarthropathy and to assess the agreement in using these scores. Three radiologists assessed 45 scans (Siemens Avanto 1.5T, dedicated foot and ankle coil) and scored independently twenty-two bones (proximal phalanges, medial and lateral sesamoids, metatarsals, tarsals, distal tibial plafond, and medial and lateral malleoli) for BMO (0—no oedema, 1—oedema < 50% of bone volume, and 2—oedema > 50% of bone volume) and fracture (0—no fracture, 1—fracture, and 2—collapse/fragmentation). Interobserver agreement and intraobserver agreement were measured using multilevel modelling and intraclass correlation (ICC). The interobserver agreement for the total BMO and fracture scores was very good (ICC = 0.83, 95% confidence intervals (CI) 0.76, 0.91) and good (ICC = 0.62; 95% CI 0.48, 0.76), respectively. The intraobserver agreement for the total BMO and fracture scores was good (ICC = 0.78, 95% CI 0.6, 0.95) and fair to moderate (ICC = 0.44; 95% CI 0.14, 0.74), respectively. The proposed BMO and fracture scores are reliable and can be used to grade the extent of bone damage in the active Charcot foot. PMID:29230422

Lockheed Martin Space Systems Company Optical Payloads Center of Excellence is in process of standing up the Robotic Optical Assembly System (ROAS) capability at Lockheed Martin Coherent Technologies in Colorado. This currently implemented Robotic Optical Assembly has enabled Lockheed Martin to create world-leading, ultra-lowSWAP photonic devices using a closed-loop control robot to precisely position and align micro-optics with a potential fill factor of >25 optics per square inch. This paper will discuss the anticipated applications and optical capability when ROAS is fully operational, as well as challenge the audience to update their "rules of thumb" and best practices when designing low-SWAP optical-mechanical systems that take advantage of Lockheed Martin's ROAS capability. This paper will reveal demonstrated optical pointing and stability performance achievable with ROAS and why we believe these optical specifications are relevant for the majority of anticipated applications. After a high level overview of the ROAS current state, this paper will focus in on recent results of the "Reworkable Micro-Optics Mounting IRAD". Results from this IRAD will correlate to the anticipated optical specifications required for relevant applications.

Jean Rotz and the Marine Chart, 1542

Taylor, E. G. R.

This paper was first published in the Journal in 1954 (Vol. 7, p. 138). It is followed by comments from Michael Richey.At the time (1542) when Jean Rotz presented Henry VIII with a variation compass, and an accompanying treatise on its making and use, the question of magnetic variation was an acute one. It formed part of a wider controversy concerning the general validity of the sea-chart which had been raised among seamen. As to this, Dr Pedro Nunez, writing a treatise in 1537 addressed to his friend and pupil the Infante Dom Luys of Portugal, said that there were skilled pilots who derided the chart and declared it to be - the falsest thing in the world. Hastening to its defence, Nunez dealt at length with the navigating errors introduced by ignoring the convergence of the meridians, and showed besides that a rhumb, or line of constant bearing was a spiral curve on the globe.

Jeans that fit: weighing the mass of the Milky Way analogues in the ΛCDM universe

The spherical Jeans equation is a widely used tool for dynamical study of gravitating systems in astronomy. Here, we test its efficacy in robustly weighing the mass of Milky Way analogues, given they need not be in equilibrium or even spherical. Utilizing Milky Way stellar haloes simulated in accordance with Λ cold dark matter (ΛCDM) cosmology by Bullock and Johnston and analysing them under the Jeans formalism, we recover the underlying mass distribution of the parent galaxy, within distance r/kpc ∈ [10, 100], with a bias of ˜ 12 per cent and a dispersion of ˜ 14 per cent. Additionally, the mass profiles of triaxial dark matter haloes taken from the SURFS simulation, within scaled radius 0.2 < r/rmax < 3, are measured with a bias of ˜ - 2.4 per cent and a dispersion of ˜ 10 per cent. The obtained dispersion is not because of Poisson noise due to small particle numbers as it is twice the later. We interpret the dispersion to be due to the inherent nature of the ΛCDM haloes, for example being aspherical and out-of-equilibrium. Hence, the dispersion obtained for stellar haloes sets a limit of about 12 per cent (after adjusting for random uncertainty) on the accuracy with which the mass profiles of the Milky Way-like galaxies can be reconstructed using the spherical Jeans equation. This limit is independent of the quantity and quality of the observational data. The reason for a non-zero bias is not clear, hence its interpretation is not obvious at this stage.

When the Jeans Do Not Fit: How Stellar Feedback Drives Stellar Kinematics and Complicates Dynamical Modeling in Low-mass Galaxies

DOE Office of Scientific and Technical Information (OSTI.GOV)

El-Badry, Kareem; Quataert, Eliot; Wetzel, Andrew R.

In low-mass galaxies, stellar feedback can drive gas outflows that generate non-equilibrium fluctuations in the gravitational potential. Using cosmological zoom-in baryonic simulations from the Feedback in Realistic Environments project, we investigate how these fluctuations affect stellar kinematics and the reliability of Jeans dynamical modeling in low-mass galaxies. We find that stellar velocity dispersion and anisotropy profiles fluctuate significantly over the course of galaxies’ starburst cycles. We therefore predict an observable correlation between star formation rate and stellar kinematics: dwarf galaxies with higher recent star formation rates should have systemically higher stellar velocity dispersions. This prediction provides an observational test ofmore » the role of stellar feedback in regulating both stellar and dark-matter densities in dwarf galaxies. We find that Jeans modeling, which treats galaxies as virialized systems in dynamical equilibrium, overestimates a galaxy’s dynamical mass during periods of post-starburst gas outflow and underestimates it during periods of net inflow. Short-timescale potential fluctuations lead to typical errors of ∼20% in dynamical mass estimates, even if full three-dimensional stellar kinematics—including the orbital anisotropy—are known exactly. When orbital anisotropy is not known a priori, typical mass errors arising from non-equilibrium fluctuations in the potential are larger than those arising from the mass-anisotropy degeneracy. However, Jeans modeling alone cannot reliably constrain the orbital anisotropy, and problematically, it often favors anisotropy models that do not reflect the true profile. If galaxies completely lose their gas and cease forming stars, fluctuations in the potential subside, and Jeans modeling becomes much more reliable.« less

Linenger transferred to Mir during the last docking mission, STS-81; he will return to Earth on Atlantis. Foale is slated to remain on Mir for about four months until he is replaced in September by STS-86 Mission Specialist Wendy B. Lawrence. During the five days Atlantis is scheduled to be docked with the Mir, the STS-84 crew and the Mir 23 crew, including two Russian cosmonauts, Commander Vasily Tsibliev and Flight Engineer Alexander Lazutkin, will participate in joint experiments. The STS-84 mission also will involve the transfer of more than 7,300 pounds of water, logistics and science equipment to and from the Mir. Atlantis is carrying a nearly 300-pound oxygen generator to replace one of two Mir units which have experienced malfunctions. The oxygen it generates is used for breathing by the Mir crew.

XVI European Charcot Foundation Lecture: Nutrition and environment, can MS be prevented?

2012-01-01

Multiple sclerosis is a relatively common debilitating neurologic disease that affects people in early adulthood. While the characteristic pathology of MS has been well described, the etiology of the disease is not well understood, despite decades of research and the identification of strong genetic and environmental candidates for susceptibility. A question central to all diseases, but posed specifically for MS at the XVI European Charcot Foundation Lecture, was ‘Can MS be prevented?’ To address this question, we have evaluated the available data regarding nutritional and environmental factors that may be related to MS susceptibility and suggest the extent to which a potential intervention may reduce disease burden. It is our opinion that intervention, particularly supplementation with vitamin D, could have a dramatic impact on disease prevalence. Understanding that any intervention or behavioral modification will surely act in the context of genetic susceptibility and unidentified stochastic events, it is likely that not all MS is ‘preventable’. Epidemiologic observation has provided key insights into environmental and nutritional factors that may alter one’s susceptibility to MS, however, there are still many questions in unraveling the etiology of this complex disease.

We discuss solutions of Vlasov-Einstein equation for collisionless dark matter particles in the context of a flat Friedmann universe. We show that, after decoupling from the primordial plasma, the dark matter phase-space density indicator Q = ρ/(σ{sub 1D}{sup 2}){sup 3/2} remains constant during the expansion of the universe, prior to structure formation. This well known result is valid for non-relativistic particles and is not ''observer dependent'' as in solutions derived from the Vlasov-Poisson system. In the linear regime, the inclusion of velocity dispersion effects permits to define a physical Jeans length for collisionless matter as function of the primordial phase-spacemore » density indicator: λ{sub J} = (5π/G){sup 1/2}Q{sup −1/3}ρ{sub dm}{sup −1/6}. The comoving Jeans wavenumber at matter-radiation equality is smaller by a factor of 2-3 than the comoving wavenumber due to free-streaming, contributing to the cut-off of the density fluctuation power spectrum at the lowest scales. We discuss the physical differences between these two scales. For dark matter particles of mass equal to 200 GeV, the derived Jeans mass is 4.3 × 10{sup −6}M{sub ⊙}.« less

Changes in isolation, inbreeding, population subdivision, and isonymous relationships are examined in six Quechua communities from the upper valley of the Ichu River in the Peruvian Central Andes (3700 m). All marriages registered between 1825 and 1914 in the Parish of Santa Ana were analyzed. The data (1680 marriages) were divided into 2 periods (1825-1870 and 1871-1914) and into the 6 villages that constitute the parish. Endogamy rates are between 81% and 100%, indicating high levels of reproductive isolation. The inbreeding indicated by isonymy (Ft, Fr, and Fn) is lower than in other mountain populations studied. Isonymy values, calculated from the different surname combinations made possible by the Ibero-American Surnames System, indicate a strong rejection of consanguineous marriages, particularly between patrilineal relatives, in agreement with the parental structure typical of Andean populations. The comparison between observed and expected repeated-pair values reveals a moderate level of subdivision within populations, which could be related to cultural and socioeconomic factors. Nonmetric multidimensional scaling was used to investigate temporal changes in the isonymous relationships among the communities. The results reveal a decrease in the interpopulational variability measured by surnames, in agreement with an increase in exogamy. Surnames and data contained in historical and demographic records yield reliable information, and they can be used to reconstruct the biological history of Amerindian populations over the last few centuries.

Charcot-Marie-Tooth neuropathy (CMT) 2E/1F is caused by mutations in the neurofilament light-chain polypeptide (NEFL) gene. Giant axons are a histological hallmark frequently seen in nerves of patients with CMT2E. We describe the case of a 43-year-old patient with a painful, predominantly sensory neuropathy. The patient's sural nerve biopsy showed multiple giant axons.

Severe neuropathy is a known adverse effect of vincristine in patients with Charcot-Marie-Tooth disease (CMT). We present the case of a 16-year-old girl with anaplastic medulloblastoma treated with gross total resection and high-dose craniospinal radiation with adjuvant vincristine chemotherapy who developed acute-onset severe quadriplegia and vocal cord paralysis. Vincristine and radiation therapy were discontinued. Although her neuropathy slowly improved over several weeks, she developed metastatic extraneural medulloblastoma and died 5 months after diagnosis. Subsequent genetic testing revealed previously asymptomatic and undiagnosed CMT1A. Our case highlights the importance of early recognition of acute vincristine neurotoxicity that should raise suspicion of an underlying hereditary neuropathy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Science at Hampton Normal and Agricultural Institute, 1868-1893

NASA Astrophysics Data System (ADS)

Tucker, Linda Bart

Science had a variety of uses at Hampton Normal and Agricultural Institute, a private, missionary school supported by northern whites and Virginia's black land grant school from 1872 to 1920. Samuel Chapman Armstrong, principal for the first twenty-five years (1868-1893), advocated not classical but scientific studies, primarily as applied science to improve lives and "civilize" blacks and Indians. Agriculture and mechanics were practiced in Hampton's industries, where students worked their way through school. They were organized for production rather than instruction, though Armstrong claimed that labor had a moral value and that practical experience was valuable learning. In contrast to works by James D. Anderson and Donald Spivey, this study stresses the pragmatic, business purposes of Hampton's industries rather than any ideological agenda. Problems with providing specialized facilities, apparatus, and teachers made it difficult for Hampton to provide rigorous, graded science instruction. Students learned of practical applications of science in agricultural lectures and in such classes as physiology. However, the curriculum was designed for teacher training, using broad, elementary science for general knowledge, to train minds, and to make adult remedial language lessons more effective. Not surprisingly, very few graduates pursued careers which required more than general science studies. Besides the utilitarian and disciplinary purposes, Hampton used science to discourage superstitious ideas in religion. Armstrong also argued for racially distinctive education for blacks and Indians on the basis of scientific ideas about cultural evolution and inheritance of the experience of past generations. In practice, however, Hampton teachers adapted mainstream tools and methods of instruction. Not all teachers shared Armstrong's racial views, and several demonstrated concern for students, confidence in their ability, and professional interest in advancing them as

Our aim is to investigate starvation as cause of death and social and demographic consequences in the Croatian Quarnero and its hinterland between 1816 and 1825, paying particular attention to the infamous "year of famine" 1817. Our sources were: registers of births, marriages, and deaths from 21 parishes kept at the Croatian State Archives in Rijeka and Zagreb. We collected and processed data for statistical analysis according to the date of baptism (birth), marriage, and death, and according to sex and age. Our focus was on recorded causes of death. Between 1816 and 1825, 15,701 children were baptised (born), and 11,021 people died. Starvation was recorded as cause of death in 255 cases, of which 198 were recorded in the infamous 1817. It was the only year with negative growth in virtually all parishes, with the birth-to-death ratio of 1147:1545. In 1817, the proportion of death by starvation to the total death rate was 12.8% for the entire area, with the highest share recorded in Veprinac (33.3%), Crikvenica (23.3%), and Kastav (15.8%). Death by starvation was more common in men than in women (56.7% vs. 43.3%, respectively). Age distribution was as follows; in the population below 20 years of age the death rate was 42 (16.5% of total deaths), but the most affected age group were infants and children aged 1-4 years (69.0%) whereas in adult population the death rate was 213 (83.5% of total deaths) and the most affected group were the elderly between 60 and 69 years (26.3%). Analysis shows lower birth and marriage rates between 1816 and 1818, followed by a steep rise and a plateau with minimal variation. This study shows that the Croatian Quarnero and its hinterland suffered a great famine in the early 19th century and 1817 in particular, which had left a deep mark on local demography, just like in the neighbouring parts of Croatia and Europe.

It has been described that many Charcot-Marie-Tooth syndrome type 2 patients are affected by a very disabling type of tremor syndrome, the pathophysiology of which remains unclear. Deep brain stimulation (DBS) has been successfully applied to treat most types of tremors by implanting electrodes in the ventral intermediate nucleus of the thalamus (Vim). We used DBS applied to the Vim in 2 patients with severe axonal inherited polyneuropathies who developed a disabling tremor. Both patients responded positively to stimulation, with a marked reduction of the tremor and with an improvement of their quality of life. We report 2 cases of tremor associated with a hereditary neuropathy with a good response to DBS. © 2017 S. Karger AG, Basel.

Ecological Energetics of an Abundant Aerial Insectivore, the Purple Martin

2013-01-01

The atmospheric boundary layer and lower free atmosphere, or aerosphere, is increasingly important for human transportation, communication, environmental monitoring, and energy production. The impacts of anthropogenic encroachment into aerial habitats are not well understood. Insectivorous birds and bats are inherently valuable components of biodiversity and play an integral role in aerial trophic dynamics. Many of these insectivores are experiencing range-wide population declines. As a first step toward gaging the potential impacts of these declines on the aerosphere’s trophic system, estimates of the biomass and energy consumed by aerial insectivores are needed. We developed a suite of energetics models for one of the largest and most common avian aerial insectivores in North America, the Purple Martin ( Progne subis ). The base model estimated that Purple Martins consumed 412 (± 104) billion insects*y-1 with a biomass of 115,860 (± 29,192) metric tonnes*y-1. During the breeding season Purple Martins consume 10.3 (+ 3.0) kg of prey biomass per km3 of aerial habitat, equal to about 36,000 individual insects*km-3. Based on these calculations, the cumulative seasonal consumption of insects*km-3 is greater in North America during the breeding season than during other phases of the annual cycle, however the maximum daily insect consumption*km-3 occurs during fall migration. This analysis provides the first range-wide quantitative estimate of the magnitude of the trophic impact of this large and common aerial insectivore. Future studies could use a similar modeling approach to estimate impacts of the entire guild of aerial insectivores at a variety of temporal and spatial scales. These analyses would inform our understanding of the impact of population declines among aerial insectivores on the aerosphere’s trophic dynamics. PMID:24086755

[Armand-Jean de Mauvillain (1620-1685), Molière's friend and counsellor, Dean of the Faculté de médecine de Paris (1666-1668)].

2005-01-01

Armand-Jean de Mauvillain was Marguerite Cardinal's and Jean de Mauvillain's son. Jean de Mauvillain was successively the King's and Gaston d'Orléans surgeon. His ancestors were native of the Poitou region. The Mauvillains' genealogy has been documented. Armand-Jean de Mauvillain completed his medical studies in Paris and graduated on May 19, 1649. He was appointed "Docteur-régent" on Februrary 3, 1650 and professor of botany in 1655. He was dismissed from his position at the Faculté de médecine for four years due to a quarrel with the Dean Antoine Blondel. Then he resumed his former position and was elected Dean in 1666. In 1650, he married Gemme Cornuty the daughter of the "Docteur-régent" Jacques Cornuty and Anne Bergeret. Jacques Cornuty was the son of Georges Cornuty, a former Dean of the Faculté de médecine (1608-1610). Mauvillain and his wife had four children: Armand-Jean, also future "Docteur-régent", Guillaume, Nicolas and Louise-Angélique.His property inventory enables us to discover his living conditions, his collection of books and the value of his belongings. His role as Molière's counsellor is disputable. The actual date of his first meeting with the famous comedian has not been ascertained. The geneaology of de Mauvillain's family has been documented from the end of the sixteenth century to the middle of the eighteenth century. Its members counted a surgeon, a priest, physicians and lawyers. These commendable activities were in accordance with those traditionally practised by the Ancien Regime middle class members.

Precipitation history and ecosystem response to multidecadal precipitation variability in the Mojave Desert region, 1893-2001

USGS Publications Warehouse

Hereford, R.; Webb, R.H.; Longpre, C.I.

2006-01-01

Precipitation varied substantially in the Mojave Desert through the 20th century in a manner broadly similar to the other warm North American deserts. Episodes of drought and prolonged dry conditions (1893-1904, ca. 1942-1975, and 1999-present) alternated with relatively wet periods (1905-ca. 1941 and ca. 1976-1998), probably because of global-scale climate fluctuations. These are the El Nin??o-Southern Oscillation that affects interannual climate and the Pacific Decadal Oscillation that evidently causes decadal-scale variability such as prolonged dry and wet episodes. Studies done in the late 20th century demonstrate that precipitation fluctuations affected populations of perennial vegetation, annuals, and small herbivores. Landscape rephotography reveals that several species, particularly creosote bush, increased in size and density during the ca. 1976-1998 wet period. A brief, intense drought from 1989 to 1991 and the ongoing drought caused widespread mortality of certain species; for example, chenopods and perennial grasses suffered up to 100% mortality. Drought pruning, the shedding of above-ground biomass to reduce carbon allocation, increased substantially during drought. Overall, drought had the greatest influence on the Mojave Desert ecosystem. ?? 2006.

Background : Young people (18-25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, diet behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore diet behaviour among 18-25 year olds with influential factors including attitudes, motivators and barriers. Methods : An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at University/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted and the results from this were incorporated into the qualitative phase. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi-staged modelling to analyse the quantitative data. 'Framework Analysis' was used to analyse the focus groups. Results : 1313 questionnaires were analysed. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the survey, 40% of young people reported eating an adequate amount of fruits and vegetables and 59% eating regular meals, but 32% reported unhealthy snacking. Based on the statistical modelling, positive attitudes towards diet and high intention (89%), did not translate into healthy diet behaviour. From the focus group discussions, the main motivators for diet behaviour were 'self-appearance' and having 'variety of food'. There were mixed opinions on 'cost' of food and 'taste'. Conclusion : Elements deemed really important to young people have been identified. This mixed method study is the largest in this vulnerable and neglected group covering a wide spectrum of the community. It provides

2017-07-01

Dominant mutations in the MORC2 gene have recently been shown to cause axonal Charcot-Marie-Tooth (CMT) disease, but the cellular function of MORC2 is poorly understood. Here, through a genome-wide CRISPR-Cas9-mediated forward genetic screen, we identified MORC2 as an essential gene required for epigenetic silencing by the HUSH complex. HUSH recruits MORC2 to target sites in heterochromatin. We exploited a new method, differential viral accessibility (DIVA), to show that loss of MORC2 results in chromatin decompaction at these target loci, which is concomitant with a loss of H3K9me3 deposition and transcriptional derepression. The ATPase activity of MORC2 is critical for HUSH-mediated silencing, and the most common alteration affecting the ATPase domain in CMT patients (p.Arg252Trp) hyperactivates HUSH-mediated repression in neuronal cells. These data define a critical role for MORC2 in epigenetic silencing by the HUSH complex and provide a mechanistic basis underpinning the role of MORC2 mutations in CMT disease.

1998-11-01

The purpose of this article is to discuss how the computer software program MARTIN and social marketing concepts (understanding the consumer perspective, exchange, marketing mix, and segmentation) were used as organizational, analytical, and interpretive tools for qualitative data. The qualitative data are from a case study on citizen participation in a health reform policy in British Columbia. The concept of broad-based public participation is a fundamental element of health promotion and citizenship. There is a gap, however, between the promise and reality of citizen participation in health promotion. Emerging from the analysis was an understanding of the societal circumstances that inhibited or fostered participation. This article describes how the code-based, theory-building attributes of the MARTIN software facilitated a new conceptualization of participatory citizenship and generated new insights into understanding why some people participate and others do not.

Cleanliness verification process at Martin Marietta Astronautics

The Montreal Protocol and the 1990 Clean Air Act Amendments mandate CFC-113, other chlorinated fluorocarbons (CFC's) and 1,1,1-Trichloroethane (TCA) be banned from production after December 31, 1995. In response to increasing pressures, the Air Force has formulated policy that prohibits purchase of these solvents for Air Force use after April 1, 1994. In response to the Air Force policy, Martin Marietta Astronautics is in the process of eliminating all CFC's and TCA from use at the Engineering Propulsion Laboratory (EPL), located on Air Force property PJKS. Gross and precision cleaning operations are currently performed on spacecraft components at EPL. The final step of the operation is a rinse with a solvent, typically CFC-113. This solvent is then analyzed for nonvolatile residue (NVR), particle count and total filterable solids (TFS) to determine cleanliness of the parts. The CFC-113 used in this process must be replaced in response to the above policies. Martin Marietta Astronautics, under contract to the Air Force, is currently evaluating and testing alternatives for a cleanliness verification solvent. Completion of test is scheduled for May, 1994. Evaluation of the alternative solvents follows a three step approach. This first is initial testing of solvents picked from literature searches and analysis. The second step is detailed testing of the top candidates from the initial test phase. The final step is implementation and validation of the chosen alternative(s). Testing will include contaminant removal, nonvolatile residue, material compatibility and propellant compatibility. Typical materials and contaminants will be tested with a wide range of solvents. Final results of the three steps will be presented as well as the implementation plan for solvent replacement.

Obstructive sleep apnoea (OSA) and restless legs syndrome (RLS) have been reported in Charcot-Marie-Tooth disease (CMT) type 1A and axonal subtypes of CMT, respectively. The aim of this case-control study was to investigate both prevalence and severity of OSA, RLS and periodic limb movements in sleep (PLMS) in adult patients with genetically proven CMT1. 61 patients with CMT1 and 61 insomnic control subjects were matched for age, sex, and Body Mass Index. Neurological disability in patients with CMT was assessed using the Functional Disability Scale (FDS). RLS diagnosis was based on a screening questionnaire and structured clinical interviews. All participants underwent overnight polysomnography. OSA was present in 37.7% of patients with CMT1 and 4.9% of controls (p<0.0001). The mean Apnoea Hypoponea Index (AHI) was significantly higher in patients with CMT1 than in control individuals (9.1/h vs 1.2/h). RLS was present in 40.9% of patients with CMT1 and in 16.4% of controls (p<0.001). In the CMT1 group, OSA was significantly more common in men and RLS in women. The AHI correlated with both age and the FDS score, the latter being a significant independent predictor of OSA. PLMS were found in 41.0% of patients with CMT1, but were not correlated with measures of sleep quality. In addition to known risk factors, CMT may predispose to OSA. RLS is highly prevalent not only in axonal subtypes of CMT but also in primarily demyelinating subforms of CMT. PLMS are common in CMT1, but do not significantly impair sleep quality.

Effects of Self-Selected Exercise on Strength in Charcot-Marie-Tooth Disease Subtypes.

PubMed

Djordjevic, Djurdja; Fell, Sabrina; Baker, Steven

2017-09-01

Preliminary studies have supported the utility of exercise as a treatment for Charcot-Marie-Tooth disease (CMT) patients. Despite being the most common inherited neuropathy, there remains a paucity of guidelines for CMT management. A retrospective chart review was performed on 297 CMT patients. Self-reported exercise and strength results from standardized dynamometer testing were obtained from adult patients' first visits. Values were converted and analyzed based on previously reported age- and sex-matched normative values. Participants with CMT2 had greater strength values than those with CMT1 in hand grip, elbow flexion, and dorsiflexion (p<0.05). Participants with CMT1 and CMT2 who exercised were statistically significantly stronger in elbow flexion and dorsiflexion than those who did not exercise. These preliminary results suggest that self-directed exercise is associated with greater strength in CMT patients of both CMT1 and CMT2 subtypes. Self-directed exercise may be a convenient, sustainable, and effective method of improving strength and decreasing disability in this population. Future research should explore the type of exercise prescription that best addresses the needs of the CMT population.

Aerobic anti-gravity exercise in patients with Charcot-Marie-Tooth disease types 1A and X: A pilot study.

PubMed

Knak, Kirsten L; Andersen, Linda K; Vissing, John

2017-12-01

Charcot-Marie-Tooth (CMT) disease is a hereditary neuropathy associated with impaired walking capacity. Some patients are too weak in the lower extremity muscles to walk at gravity with sufficient intensity or duration to gain benefit. The aim was to investigate the effect of aerobic anti-gravity exercise in weak patients with CMT 1A and X. Five adult patients performed moderate-intensity aerobic anti-gravity exercise 3/week for 10 weeks. There was a significant positive difference in Berg balance scale and postural stability test between test occasions, and walking distance in the 6-min walk test trended to increase. The study indicates that the anti-gravity treadmill training of patients with CMT should be pursued in larger CMT cohorts.

Initial clinical recognition of "paralysis agitans" by James Parkinson was expanded by Jean-Martin Charcot, who recognized additional clinical findings of his own, such as slowness (distinct from paralysis), rigidity (distinct from spasticity) and characteristic countenance. Charcot assembled these findings under the umbrella of "Parkinson disease (PD)". This purely clinical concept was so prescient and penetrating that subsequent neuropathological and biochemical evidences were ordered along this axis to establish the nigra-central trinity of PD (dopamine depletion, nigral lesion with Lewy bodies: LBs). Although dramatic efficacy of levodopa boosted an enthusiasm for this nigra-centralism, extranigral lesions were identified, especially after identification of alpha-synuclein (αS) as a major constituent of LBs. Frequent αS lesions in the lower brainstem with their presumed upward spread were coupled with the self-propagating property of αS molecule, as a molecular template, to constitute the prion-Braak hypothesis. This hybrid concept might expectedly explain clinical, structural and biochemical features of PD/dementia with Lewy bodies (DLB) as if they were stereotypic. In spite of this ordered explanation, recent studies have demonstrated unexpectedly that αS lesions in the human brain, as well as their corresponding clinical manifestations, are much more disordered. Even with such a chaos of LB disorders, affected neuronal groups are uniformly characterized by hyperbranching axons, which may facilitate distal-dominant degeneration and retrograde progression of LB-related degeneration along axons as a fundamental structural order to template LB disorders. This "structural template" hypothesis may explain why: (i) some selective groups are prone to develop Lewy pathology; (ii) their clinical manifestations (especially non-motor components) are vague and generalized without somatotopic accentuation; (iii) distal axons and terminals are preferentially affected

We studied the relationship between the genotype and clinical phenotype in 27 families with dominant X-linked Charcot-Marie-Tooth (CMTX1) neuropathy. Twenty-two families showed mutations in the coding region of the connexin32 (cx32) gene. The mutations include four nonsense mutations, eight missense mutations, two medium size deletions, and one insertion. Most missense mutations showed a mild clinical phenotype (five out of eight), whereas all nonsense mutations, the larger of the two deletions, and the insertion that produced frameshifts showed severe phenotypes. Five CMTX1 families with mild clinical phenotype showed no point mutations of the cx32 gene coding region. Three of these familiesmore » showed positive genetic linkage with the markers of the Xq13.1 region. The genetic linkage of the remaining two families could not be evaluated because of their small size. 25 refs., 1 fig., 1 tab.« less

2004-03-01

Jean-Dominique Cassini, for whom the Cassini mission to Saturn is named, is best known for his early understanding of that planet's rings. This article is an overview of his influential career in astronomy and other scientific fields.= Born in Italy in1625 and formally educated at an early age, he was a professor of astronomy at the University of Bologna, a leading center of learning in Europe of the time. He was an early observer of Jupiter, Mars, and Venus. He is best known for constructing a giant pinhole camera in a cathedral that he used with a meridian line on the floor to track the Sun's image through the year, thus providing the Catholic Church with a reliable calendar. Cassini also used the pinhole camera observations to calculate the variation in the distance between the Sun and Earth, thus lending support to the Copernican (Sun-centered) view of the solar system. Cassini moved to Paris at the request of King Louis XIV, originally to oversee the surveying needed for a new map system of France, but ultimately he took over as the director of the Paris Observatory. Cassini's descendants ran the observatory there for the following century.

Intermittent fasting alleviates the neuropathic phenotype in a mouse model of Charcot-Marie-Tooth disease

Charcot-Marie-Tooth type 1A (CMT1A) neuropathies linked to the misexpression of peripheral myelin protein 22 (PMP22) are progressive demyelinating disorders of the peripheral nervous system. In this study we asked whether dietary restriction by intermittent fasting (IF) could alleviate the neuropathic phenotype in the Trembler J (TrJ) mouse model of CMT1A. Our results show that neuropathic mice kept on a five month long IF regimen had improved locomotor performance compared to ad libitum (AL) fed littermates. The functional benefits of this dietary intervention are associated with an increased expression of myelin proteins combined with a thicker myelin sheath, less redundant basal lamina, and a reduction in aberrant Schwann cell proliferation. These morphological improvements are accompanied by a decrease in PMP22 protein aggregates, and enhanced expression of cytosolic chaperones and constituents of the autophagy-lysosomal pathway. These results indicate that dietary restriction is beneficial for peripheral nerve function in TrJ neuropathic mice, as it promotes the maintenance of locomotor performance. PMID:19320048

Hyper-activation of HUSH complex function by Charcot-Marie-Tooth disease mutation in MORC2

2017-01-01

Dominant mutations in the MORC2 gene have recently been shown to cause axonal Charcot-Marie-Tooth (CMT) disease, but the cellular function of MORC2 is poorly understood. Here, through a genome-wide CRISPR/Cas9-mediated forward genetic screen, we identify MORC2 as an essential gene required for epigenetic silencing by the HUSH complex. HUSH recruits MORC2 to target sites in heterochromatin. We exploit a new method – Differential Viral Accessibility (DIVA) – to show that loss of MORC2 results in chromatin decompaction at these target loci, which is concomitant with a loss of H3K9me3 deposition and transcriptional derepression. The ATPase activity of MORC2 is critical for HUSH-mediated silencing, and the most common mutation affecting the ATPase domain found in CMT patients (R252W) hyper-activates HUSH-mediated repression in neuronal cells. These data define a critical role for MORC2 in epigenetic silencing by the HUSH complex and provide a mechanistic basis underpinning the role of MORC2 mutations in CMT disease. PMID:28581500

Charcot-Marie-Tooth (CMT) disease is a hereditary neuropathy of motor and sensory impairment with distal predominance. Atrophy and weakness of lower limbs are the first signs of the disease. It can be classified, with the aid of electromyography and nerve conduction studies, as demyelinating (CMT1) or axonal (CMT2). Clinical and neurophysiological investigation of a large multigenerational family with CMT2 with autosomal dominant mode of transmission. Fifty individuals were evaluated and neurophysiological studies performed in 22 patients. Thirty individuals had clinical signs of motor-sensory neuropathy. Babinski sign was present in 14 individuals. Neurophysiological study showed motor-sensory axonal polyneuropathy. The clinical and neurophysiological characteristics of this family does not differ from those observed with other forms of CMT, except for the high prevalence of Babinski sign.

Reanalysis of the 1893 heat wave in France through offline data assimilation in a downscaled ensemble meteorological reconstruction

NASA Astrophysics Data System (ADS)

Devers, Alexandre; Vidal, Jean-Philippe; Lauvernet, Claire; Graff, Benjamin

2017-04-01

The knowledge of historical French weather has recently been improved through the development of the SCOPE (Spatially COherent Probabilistic Extended) Climate reconstruction, a probabilistic high-resolution daily reconstruction of precipitation and temperature covering the period 1871-2012 and based on the statistical downscaling of the Twentieth Century Reanalysis (Caillouet et al., 2016). However, historical surface observations - even though rather scarce and sparse - do exist from at least the beginning of the period considered, and this information does not currently feed SCOPE Climate reconstructions. The goal of this study is therefore to assimilate these historical observations into SCOPE Climate reconstructions in order to build a 150-year meteorological reanalysis over France. This study considers "offline" data assimilation methods - Kalman filtering methods like the Ensemble Square Root Filter - that have successfully been used in recent paleoclimate studies, i.e. at much larger temporal and spatial scales (see e.g. Bhend et al., 2012). These methods are here applied for reconstructing the 8-24 August 1893 heat wave in France, using all available daily temperature observations from that period. Temperatures reached that summer were indeed compared at the time to those of Senegal (Garnier, 2012). Results show a spatially coherent view of the heat wave at the national scale as well as a reduced uncertainty compared to initial meteorological reconstructions, thus demonstrating the added value of data assimilation. In order to assess the performance of assimilation methods in a more recent context, these methods are also used to reconstruct the well-known 3-14 August 2003 heat wave by using (1) all available stations, and (2) the same station density as in August 1893, the rest of the observations being saved for validation. This analysis allows comparing two heat waves having occurred 100 years apart in France with different associated uncertainties, in

Villalon, Eric; Dale, Jeffrey M.; Jones, Maria; Shen, Hailian; Garcia, Michael L.

2018-01-01

Charcot-Marie-Tooth disease (CMT) is the most commonly inherited peripheral neuropathy. CMT disease signs include distal limb neuropathy, abnormal gait, sensory defects, and deafness. We generated a novel line of CMT2E mice expressing hNF-LE397K, which displayed muscle atrophy of the lower limbs without denervation, proximal reduction in large caliber axons, and decreased nerve conduction velocity. In this study, we challenged wild type, hNF-L, and hNF-LE397K mice with crush injury to the sciatic nerve. We analyzed functional recovery by measuring toe spread and analyzed gaitusing the Catwalk system. hNF-LE397K mice demonstrated reduced recovery from nerve injury consistent with increased susceptibility to neuropathy observed in CMT patients. In addition, hNF-LE397K developed a permanent reduction in their ability to weight bear, increased mechanical allodynia, and premature gait shift in the injured limb, which led to increasingly disrupted interlimb coordination in hNF-LE397K. Exacerbation of neuropathy after injury and identification of gait alterations in combination with previously described pathology suggests that hNF-LE397K mice recapitulate many of clinical signs associated with CMT2. Therefore, hNF-LE397K mice provide a model for determining the efficacy of novel therapies. PMID:26423936

To evaluate lower urinary tract (LUT), bowel, and sexual dysfunctions in a series of patients with Charcot-Marie-Tooth disease (CMT). A cohort of 58 patients and 54 healthy controls filled out the International Prostate Symptoms Score (IPSS) and the International Consultation on Incontinence Modular (ICIQ) Questionnaires to assess their symptoms and their impact on the patient's quality of life. On the IPSS questionnaire, CMT patients reported a significantly higher score compared with the healthy controls in 7 of 8 questions. The ICIQ-male LUT symptoms questionnaire revealed a significantly higher score in 7 of 26 questions. In the ICIQ-female LUT questionnaire, a significantly higher score was observed in 13 of 24 questions. When assessing the bowel function in CMT patients using the ICIQ-bowel questionnaire, a significantly higher score in 30 of 40 questions was noted. No differences in sexual function were found in either group. The occurrence of the LUT symptoms and bowel dysfunctions in CMT patients was significantly higher when compared with an age-matched control group. The symptoms were more frequent in female patients. The findings suggest that autonomic dysfunction should be evaluated and included in the diagnostic approach and care of CMT patients. © 2013 John Wiley & Sons A/S.

In this study the abundant peripheral myelin protein zero (MPZ) gene, MPZ, was mapped 130 kb centromeric to the Fc receptor immunoglobulin gene cluster in band 1q22, and a major MPZ point mutation was found to cosegregate with CMT1B in one large CMT1B family.

Gold mining is responsible for most Hg pollution in developing countries. The aims of this study were to assess the levels of total Hg (T-Hg) in human hair, fish, water, macrophyte, and sediment samples in the gold mining district of San Martin de Loba, Colombia, as well as to determine fish consumption-based risks for T-Hg ingestion. T-Hg levels were measured by electrothermal atomization and atomic absorption spectroscopy. The overall mean T-Hg level in hair for humans in the mining district of San Martin de Loba was 2.12 μg/g, whereas for the reference site, Chimichagua, Cesar, it was 0.58 μg/g. Mean T-Hg levels were not different when considered within localities belonging to the mining district but differed when the comparison included Chimichagua. T-Hg levels in examined locations were weakly but significantly associated with age and height, as well as with fish consumption, except in San Martin de Loba. High T-Hg concentrations in fish were detected in Pseudoplatystoma magdaleniatum, Caquetaia kraussii, Ageneiosus pardalis, Cyrtocharax magdalenae, and Triportheus magdalenae, whereas the lowest appeared in Prochilodus magdalenae and Hemiancistrus wilsoni. In terms of Hg exposure due to fish consumption, only these last two species offer some guarantee of low risk for Hg-related health problems. Water, floating macrophytes, and sediments from effluents near mining sites also had high Hg values. In mines of San Martin de Loba and Hatillo de Loba, for instance, the geoaccumulation index (I(geo)) for sediments reached values greater than 6, indicating extreme pollution. In short, these data support the presence of a high Hg-polluted environment in this mining district, with direct risk for deleterious effects on the health of the mining communities.

We have measured the Fourier transform spectrum of carbonyl sulfide from 1825 to 2700 cm-1, using a sample enriched in both18O (94.0%) and17O (1.54%). A careful calibration yields a line-position accuracy between 1.5 and 3.0 10-5cm-1. We have observed and analyzed 118 infrared bands of which 93 are measured for the first time: 55 for18O12C32S, 20 for18O12C34S, 11 for18O12C33S, 1 for18O12C36S, 12 for17O12C32S, 4 for17O12C34S, 2 for17O12C33S, and 13 for18O13C32S. Intensities are also reported and analyzed for all those bands. The intensity accuracy is better than 10%, and the precision of approximately 1% allows us to determine some Herman-Wallis coefficients.
