    We report 10 cases of pulmonary atelectasis diagnosed by chest computed tomography in patients with neurological or muscular disease. Atelectasis was frequently seen in hypotonic patients who could not roll over on their own. The atelectases located mostly in the dorsal bronchopulmonary segments, adjacent to the heart or diaphragm. Atelectasis diminished in two patients after they became able to roll themselves over. Gravity-related lung compression by the heart and intra-abdominal organs on persistent supine position can cause pulmonary atelectasis in patients with neurological or muscular disease who can not roll over by their own power. To confirm that the prone position reduces compression of the lungs, chest computed tomography was performed in both the supine and the prone position in three patients. Sagittal images with three-dimensional computed tomographic reconstruction revealed significant sternad displacements of the heart and caudal displacements of the dorsal portion of the diaphragm on prone position compared with supine position. The prone position, motor exercises for rolling over, and biphasic cuirass ventilation are effective in reducing gravity-related lung compression. Some patients with intellectual disabilities were also able to cooperate in chest physiotherapy. Chest physiotherapy is useful in preventing atelectasis in patients with neurological or muscular disease. (author)

  4. Can delusions be understood linguistically? (United States)

    Hinzen, Wolfram; Rosselló, Joana; McKenna, Peter


    ABSTRACT Delusions are widely believed to reflect disturbed cognitive function, but the nature of this remains elusive. The “un-Cartesian” cognitive-linguistic hypothesis maintains (a) that there is no thought separate from language, that is, there is no distinct mental space removed from language where “thinking” takes place; and (b) that a somewhat broadened concept of grammar is responsible for bestowing meaning on propositions, and this among other things gives them their quality of being true or false. It is argued that a loss of propositional meaning explains why delusions are false, impossible and sometimes fantastic. A closely related abnormality, failure of linguistic embedding, can additionally account for why delusions are held with fixed conviction and are not adequately justified by the patient. The un-Cartesian linguistic approach to delusions has points of contact with Frith’s theory that inability to form meta-representations underlies a range of schizophrenic symptoms. It may also be relevant to the nature of the “second factor” in monothematic delusions in neurological disease. Finally, it can inform the current debate about whether or not delusions really are beliefs. PMID:27322493

  5. Practice guideline update summary: Corticosteroid treatment of Duchenne muscular dystrophy: Report of the Guideline Development Subcommittee of the American Academy of Neurology. (United States)

    Gloss, David; Moxley, Richard T; Ashwal, Stephen; Oskoui, Maryam


    To update the 2005 American Academy of Neurology (AAN) guideline on corticosteroid treatment of Duchenne muscular dystrophy (DMD). We systematically reviewed the literature from January 2004 to July 2014 using the AAN classification scheme for therapeutic articles and predicated recommendations on the strength of the evidence. Thirty-four studies met inclusion criteria. In children with DMD, prednisone should be offered for improving strength (Level B) and pulmonary function (Level B). Prednisone may be offered for improving timed motor function (Level C), reducing the need for scoliosis surgery (Level C), and delaying cardiomyopathy onset by 18 years of age (Level C). Deflazacort may be offered for improving strength and timed motor function and delaying age at loss of ambulation by 1.4-2.5 years (Level C). Deflazacort may be offered for improving pulmonary function, reducing the need for scoliosis surgery, delaying cardiomyopathy onset, and increasing survival at 5-15 years of follow-up (Level C for each). Deflazacort and prednisone may be equivalent in improving motor function (Level C). Prednisone may be associated with greater weight gain in the first years of treatment than deflazacort (Level C). Deflazacort may be associated with a greater risk of cataracts than prednisone (Level C). The preferred dosing regimen of prednisone is 0.75 mg/kg/d (Level B). Over 12 months, prednisone 10 mg/kg/weekend is equally effective (Level B), with no long-term data available. Prednisone 0.75 mg/kg/d is associated with significant risk of weight gain, hirsutism, and cushingoid appearance (Level B). © 2016 American Academy of Neurology.

  9. Poorly Understood Aspects of Striated Muscle Contraction

    Directory of Open Access Journals (Sweden)

    Alf Månsson


    Full Text Available Muscle contraction results from cyclic interactions between the contractile proteins myosin and actin, driven by the turnover of adenosine triphosphate (ATP. Despite intense studies, several molecular events in the contraction process are poorly understood, including the relationship between force-generation and phosphate-release in the ATP-turnover. Different aspects of the force-generating transition are reflected in the changes in tension development by muscle cells, myofibrils and single molecules upon changes in temperature, altered phosphate concentration, or length perturbations. It has been notoriously difficult to explain all these events within a given theoretical framework and to unequivocally correlate observed events with the atomic structures of the myosin motor. Other incompletely understood issues include the role of the two heads of myosin II and structural changes in the actin filaments as well as the importance of the three-dimensional order. We here review these issues in relation to controversies regarding basic physiological properties of striated muscle. We also briefly consider actomyosin mutation effects in cardiac and skeletal muscle function and the possibility to treat these defects by drugs.

  12. Cardiomyopathy in neurological disorders. (United States)

    Finsterer, Josef; Stöllberger, Claudia; Wahbi, Karim


    According to the American Heart Association, cardiomyopathies are classified as primary (solely or predominantly confined to heart muscle), secondary (those showing pathological myocardial involvement as part of a neuromuscular disorder) and those in which cardiomyopathy is the first/predominant manifestation of a neuromuscular disorder. Cardiomyopathies may be further classified as hypertrophic cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, or unclassified cardiomyopathy (noncompaction, Takotsubo-cardiomyopathy). This review focuses on secondary cardiomyopathies and those in which cardiomyopathy is the predominant manifestation of a myopathy. Any of them may cause neurological disease, and any of them may be a manifestation of a neurological disorder. Neurological disease most frequently caused by cardiomyopathies is ischemic stroke, followed by transitory ischemic attack, syncope, or vertigo. Neurological disease, which most frequently manifests with cardiomyopathies are the neuromuscular disorders. Most commonly associated with cardiomyopathies are muscular dystrophies, myofibrillar myopathies, congenital myopathies and metabolic myopathies. Management of neurological disease caused by cardiomyopathies is not at variance from the same neurological disorders due to other causes. Management of secondary cardiomyopathies is not different from that of cardiomyopathies due to other causes either. Patients with neuromuscular disorders require early cardiologic investigations and close follow-ups, patients with cardiomyopathies require neurological investigation and avoidance of muscle toxic medication if a neuromuscular disorder is diagnosed. Which patients with cardiomyopathy profit most from primary stroke prevention is unsolved and requires further investigations. Copyright © 2013 Elsevier Inc. All rights reserved.

  16. Education Research: Neurology resident education (United States)

    Mayans, David; Schneider, Logan; Adams, Nellie; Khawaja, Ayaz M.; Engstrom, John


    Objective: To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. Methods: An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Results: Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Discussion: Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. PMID:26976522

  1. Urachal tumour: case report of a poorly understood carcinoma

    Directory of Open Access Journals (Sweden)

    Vallarino Luigi


    Full Text Available Abstract Background Urachal carcinoma is an uncommon neoplasm associated with poor prognosis. Case presentation A 45-year-old man was admitted with complaints of abdominal pain and pollakisuria. A soft mass was palpable under his navel. TC-scan revealed a 11 × 6 cm tumor, which was composed of a cystic lesion arising from the urachus and a solid mass component at the urinary bladder dome. The tumor was removed surgically. Histological examination detected poor-differentiated adenocarcinoma, which had invaded the urinary bladder. The patient has been followed up without recurrence for 6 months. Conclusion The urachus is the embryological remnant of urogenital sinus and allantois. Involution usually happens before birth and urachus is present as a median umbilical ligament. The pathogenesis of urachal tumours is not fully understood. Surgery is the treatment of choice and role of adjuvant treatment is not clearly understood.

  5. Donors in Semiconductors - are they Understood in Electronic Era?

    International Nuclear Information System (INIS)

    Dmochowski, Janusz E


    The physics of semiconductors and contemporary electronics cannot be understood without impurities. The hydrogen-like shallow donor (and acceptor) state of electron (hole) bound by Coulomb electrostatic force of excess charge of impurity is used to control conductivity of semiconductors and construct semiconductor diodes, transistors and numerous types of semiconductor electronic and optoelectronic devices, including lasers. Recently, surprisingly, the physics of impurity donors appeared to be much reacher. Experimental evidence has been provided for universal existence of other types of electronic states of the same donor impurity: i) mysterious, deep, DX-type state resulting in metastability - slow hysteresis phenomena - understood as two-electron, acceptor-like state of donor impurity, formed upon large lattice distortion or rearrangement around impurity and accompanying capture of second electron, resulting in negative electron correlation energy U; ii) deep, localized, fully symmetric, A1, one-electron donor state of substitutional impurity. The latter state can be formed from the 'ordinary' shallow hydrogen-like state in the process of strong localization of electron by short range, local potential of impurity core, preserving full (A 1 ) symmetry of the substitutional impurity in the host lattice. The 'anticrossing' of the two A 1 (shallow hydrogenic and deep localized) energy levels upon transformation is observed. All types of electronic states of impurity can be universally observed for the same donor impurity and mutual transformation between different states occur upon changing experimental conditions. The knowledge about existence and properties of these n ew , molecular type, donor states in semiconductors seems still await general recognition and positive application in contemporary material and device science and engineering

    There is a wide range of indications for radiographic evaluation of possible cerebrovascular disease, since a wide range of neurologic symptoms can be encountered secondary to ischemia. Frequently the diagnosis of cerebrovascular disease is clear on clinical grounds, but radiographic evaluation is essential both to quantify the extent of disease and establish the underlying cause (e.g., vasculitis, embolus) while excluding other causes so that the proper therapy can follow

  9. Respiratory function in facioscapulohumeral muscular dystrophy 1. (United States)

    To test the hypothesis that wheelchair dependency and (kypho-)scoliosis are risk factors for developing respiratory insufficiency in facioscapulohumeral muscular dystrophy, we examined 81 patients with facioscapulohumeral muscular dystrophy 1 of varying degrees of severity ranging from ambulatory patients to wheelchair-bound patients. We examined the patients neurologically and by conducting pulmonary function tests: Forced Vital Capacity, Forced Expiratory Volume in 1 second, and static maximal inspiratory and expiratory mouth pressures. We did not find pulmonary function test abnormalities in ambulant facioscapulohumeral muscular dystrophy patients. Even though none of the patients complained of respiratory dysfunction, mild to severe respiratory insufficiency was found in more than one third of the wheelchair-dependent patients. Maximal inspiratory pressures and maximal expiratory pressures were decreased in most patients, with a trend that maximal expiratory pressures were more affected than maximal inspiratory pressures. Wheelchair-dependent patients with (kypho-)scoliosis showed the most restricted lung function. Wheelchair-dependent patients with (kypho-)scoliosis are at risk for developing respiratory function impairment. We advise examining this group of facioscapulohumeral muscular dystrophy patients periodically, even in the absence of symptoms of respiratory insufficiency, given its frequency and impact on daily life and the therapeutic consequences.

  10. How Physicians Support Mothers of Children with Duchenne Muscular Dystrophy. (United States)

    Fujino, Haruo; Saito, Toshio; Matsumura, Tsuyoshi; Shibata, Saki; Iwata, Yuko; Fujimura, Harutoshi; Shinno, Susumu; Imura, Osamu


    Communicating about Duchenne muscular dystrophy and its prognosis can be difficult for affected children and their family. We focused on how physicians provide support to the mothers of children with Duchenne muscular dystrophy who have difficulty communicating about the condition with their child. The eligible participants were certified child neurologists of the Japanese Society of Child Neurology. Participants responded to questionnaires consisting of free descriptions of a vignette of a child with Duchenne muscular dystrophy and a mother. We analyzed 263 responses of the participants. We found 4 themes on advising mothers, involving encouraging communication, family autonomy, supporting family, and considering the child's concerns. These results provide a better understanding of the communication between physicians and family members who need help sharing information with a child with Duchenne muscular dystrophy. These findings will assist clinical practitioners in supporting families and the affected children throughout the course of their illness. © The Author(s) 2015.

  13. Rhabdomyolysis featuring muscular dystrophies. (United States)

    Lahoria, Rajat; Milone, Margherita


    Rhabdomyolysis is a potentially life threatening condition of various etiology. The association between rhabdomyolysis and muscular dystrophies is under-recognized in clinical practice. To identify muscular dystrophies presenting with rhabdomyolysis at onset or as predominant feature. We retrospectively reviewed clinical and laboratory data of patients with a genetically confirmed muscular dystrophy in whom rhabdomyolysis was the presenting or main clinical manifestation. Thirteen unrelated patients (males=6; females=7) were identified. Median age at time of rhabdomyolysis was 18 years (range, 2-47) and median duration between the first episode of rhabdomyolysis and molecular diagnosis was 2 years. Fukutin-related protein (FKRP) muscular dystrophy (n=6) was the most common diagnosis, followed by anoctaminopathy-5 (n=3), calpainopathy-3 (n=2) and dystrophinopathy (n=2). Four patients experienced recurrent rhabdomyolysis. Eight patients were asymptomatic and 3 reported myalgia and exercise intolerance prior to the rhabdomyolysis. Exercise (n=6) and fever (n=4) were common triggers; rhabdomyolysis was unprovoked in 3 patients. Twelve patients required hospitalization. Baseline CK levels were elevated in all patients (median 1200 IU/L; range, 600-3600). Muscular dystrophies can present with rhabdomyolysis; FKRP mutations are particularly frequent in causing such complication. A persistently elevated CK level in patients with rhabdomyolysis warrants consideration for underlying muscular dystrophy. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Preocupações mórbidas com a imagem corporal eram tidas até recentemente como problemas eminentemente femininos. Atualmente estas preocupações também têm sido encontradas no sexo masculino. A dismorfia muscular é um subtipo do transtorno dismórfico corporal que ocorre principalmente em homens que, apesar da grande hipertrofia muscular, consideram-se pequenos e fracos. Além de estar associada a prejuízos sociais, ocupacionais, recreativos e em outras áreas do funcionamento do indivíduo, a dismorfia muscular é também um fator de risco para o abuso de esteróides anabolizantes. Este artigo aborda aspectos epidemiológicos, etiológicos e padrões clínicos da dismorfia muscular, além de tecer comentários sobre estratégias de tratamento para este transtorno.Morbid concern over body image was considered, until recently, a female issue. Nowadays, it has been viewed as a common male disorder. Muscle dysmorphia, a subtype of a body dysmorphic disorder, affects men who, despite having clear muscular hypertroph,y see themselves as frail and small. Besides being associated to major social, leisure and occupational dysfunction, muscle dysmorphia is also a risk factor for the abuse of steroids. This article describes epidemiological, etiological and clinical characteristics of muscle dysmorphia and comments on its treatment strategy.

  17. Neurology and neurologic practice in China. (United States)

    Shi, Fu-Dong; Jia, Jian-Ping


    In the wake of dramatic economic success during the past 2 decades, the specialized field of neurology has undergone a significant transformation in China. With an increase in life expectancy, the problems of aging and cognition have grown. Lifestyle alterations have been associated with an epidemiologic transition both in the incidence and etiology of stroke. These changes, together with an array of social issues and institution of health care reform, are creating challenges for practicing neurologists throughout China. Notable problems include overcrowded, decrepit facilities, overloaded physician schedules, deteriorating physician-patient relationships, and an insufficient infrastructure to accommodate patients who need specialized neurologic care. Conversely, with the creation of large and sophisticated neurology centers in many cities across the country, tremendous opportunities exist. Developments in neurologic subspecialties enable delivery of high-quality care. Clinical and translational research based on large patient populations as well as highly sophisticated technologies are emerging in many neurologic centers and pharmaceutical companies. Child neurology and neurorehabilitation will be fast-developing subdisciplines. Given China's extensive population, the growth and progress of its neurology complex, and its ever-improving quality control, it is reasonable to anticipate that Chinese neurologists will contribute notably to unraveling the pathogenic factors causing neurologic diseases and to providing new therapeutic solutions.

  18. The link between stress disorders and autonomic dysfunction in muscular dystrophy. (United States)

    Sabharwal, Rasna


    Muscular dystrophy is a progressive disease of muscle weakness, muscle atrophy and cardiac dysfunction. Patients afflicted with muscular dystrophy exhibit autonomic dysfunction along with cognitive impairment, severe depression, sadness, and anxiety. Although the psychological aspects of cardiovascular disorders and stress disorders are well known, the physiological mechanism underlying this relationship is not well understood, particularly in muscular dystrophy. Therefore, the goal of this perspective is to highlight the importance of autonomic dysfunction and psychological stress disorders in the pathogenesis of muscular dystrophy. This article will for the first time-(i) outline autonomic mechanisms that are common to both psychological stress and cardiovascular disorders in muscular dystrophy; (ii) propose therapies that would improve behavioral and autonomic functions in muscular dystrophy.

  20. Men, Muscles, and Eating Disorders: an Overview of Traditional and Muscularity-Oriented Disordered Eating. (United States)

    Lavender, Jason M; Brown, Tiffany A; Murray, Stuart B


    There is growing recognition that eating disorder (ED) symptoms, particularly those of a muscularity-oriented nature, are more common in men than previously understood. The purpose of the current review is to describe contemporary directions and implications of research on traditional and muscularity-oriented ED symptoms among males. Evidence indicates that ED symptoms occur in a substantial minority of men. Importantly, recent research has focused on muscularity-oriented body image and disordered eating in males, demonstrating the prevalence, correlates, and consequences of maladaptive muscularity-oriented attitudes and behaviors. A growing number of assessments are available to measure these constructs in males, and preliminary treatment considerations have begun to be addressed in the literature. Research on male EDs and body image is increasingly focusing on muscularity-oriented manifestations. Continued empirical work will be critical to improve our understanding of the onset, maintenance, and treatment of muscularity-oriented disordered eating in males.

    Matsumura, K.; Nakano, I.


    By means of magnetic resonance imaging (MRI), the proton spin-lattice relaxation times (T1 values) of the skeletal muscles were measured in Duchenne muscular dystrophy (DMD) carriers and normal controls. The bound water fraction (BWF) was calculated from the T1 values obtained, according to the fast proton diffusion model. In the DMD carriers, T1 values of the gluteus maximus and quadriceps femoris muscles were significantly higher, and BWFs of these muscles were significantly lower than in normal control. Degenerative muscular changes accompanied by interstitial edema were presumed responsible for this abnormality. No correlation was observed between the muscle T1 and serum creatine kinase values. The present study showed that MRI could be a useful method for studying the dynamic state of water in both normal and pathological skeletal muscles. Its possible utility for DMD carrier detection was discussed briefly. (orig.)

    Duchenne muscular dystrophy, an X-linked disorder, has an incidence of one in 5000 boys and presents in early childhood with proximal muscle weakness. Untreated boys become wheelchair bound by the age of 12 years and die of cardiorespiratory complications in their late teens to early 20s. The use of corticosteroids, non-invasive respiratory support, and active surveillance and management of associated complications have improved ambulation, function, quality of life and life expectancy. The clinical features, investigations and management of Duchenne muscular dystrophy are reviewed, as well as the latest in some of the novel therapies. © 2015 The Authors.

  10. Neurologic emergencies in sports. (United States)

    Williams, Vernon B


    Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

  11. [Neurology! Adieau? (Part 2)]. (United States)

    Szirmai, Imre


    The education of neurologists is debilitated worldwide. University professors are engaged in teaching, research and patient-care. This triple challenge is very demanding, and results in permanent insecurity of University employees. To compensate for the insufficient clinical training, some institutes in the USA employ academic staff members exclusively for teaching. The formation of new subspecialties hinders the education and training of general neurologists. At present, four generations of medical doctors are working together in hospitals. The two older generations educate the younger neurologists who have been brought up in the world of limitless network of sterile information. Therefore their manual skills at the bedside and their knowledge of emergency treatment are deficient. Demographics of medical doctors changed drastically. Twice as many women are working in neurology and psychiatry than men. Integrity of neurology is threatened by: (1) Separation of the cerebrovascular diseases from general neurology. Development of "stroke units" was facilitated by the better reimbursement for treatment and by the interest of the pharmaceutical companies. Healthcare politics promoted the split of neurology into two parts. The independent status of "stroke departments" will reduce the rest of clinical neurology to outpatient service. (2) The main argumentation to segregate the rare neurological diseases was that their research will provide benefit for the diseases with high prevalence. This argumentation serves territorial ambitions. The separation of rare diseases interferes with the teaching of differential diagnostics in neurological training. The traditional pragmatic neurology can not be retrieved. The faculty of neurology could retain its integrity by the improvement of diagnostic methods and the ever more effective drugs. Nevertheless, even the progression of neurological sciences induces dissociation of clinical neurology. Neurology shall suffer fragmentation if

    In the mid-sixties, Gary Graham, a Boeing designer, developed a cardiovascular conditioner for a planned Air Force orbiting laboratory. After the project was cancelled, Graham participated in space station conditioning studies for the Skylab program. Twenty years later, he used this expertise to develop the Shuttle 2000-1, a physical therapy and athletic development conditioner, available through Contemporary Designs. The machine is used by football teams, sports clinics and medical rehabilitation centers. Cardiovascular fitness and muscular strength development are promoted through both kinetic and plyometric exercises.

    Silva, Helga Cristina Almeida da; Hiray, Marcia; Vainzof, Mariz; Schmidt, Beny; Oliveira, Acary Souza Bulle; Amaral, José Luiz Gomes do


    Duchenne/Becker muscular dystrophy affects skeletal muscles and leads to progressive muscle weakness and risk of atypical anesthetic reactions following exposure to succinylcholine or halogenated agents. The aim of this report is to describe the investigation and diagnosis of a patient with Becker muscular dystrophy and review the care required in anesthesia. Male patient, 14 years old, referred for hyperCKemia (chronic increase of serum creatine kinase levels - CK), with CK values of 7,779-29,040IU.L -1 (normal 174IU.L -1 ). He presented with a discrete delay in motor milestones acquisition (sitting at 9 months, walking at 18 months). He had a history of liver transplantation. In the neurological examination, the patient showed difficulty in walking on one's heels, myopathic sign (hands supported on the thighs to stand), high arched palate, calf hypertrophy, winged scapulae, global muscle hypotonia and arreflexia. Spirometry showed mild restrictive respiratory insufficiency (forced vital capacity: 77% of predicted). The in vitro muscle contracture test in response to halothane and caffeine was normal. Muscular dystrophy analysis by Western blot showed reduced dystrophin (20% of normal) for both antibodies (C and N-terminal), allowing the diagnosis of Becker muscular dystrophy. On preanesthetic assessment, the history of delayed motor development, as well as clinical and/or laboratory signs of myopathy, should encourage neurological evaluation, aiming at diagnosing subclinical myopathies and planning the necessary care to prevent anesthetic complications. Duchenne/Becker muscular dystrophy, although it does not increase susceptibility to MH, may lead to atypical fatal reactions in anesthesia. Copyright © 2017 Sociedade Brasileira de Anestesiologia.

  16. Neurology in Asia. (United States)

    Tan, Chong-Tin


    Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region. © 2015 American Academy of Neurology.

  17. The future of neurology. (United States)

    Freeman, W David; Vatz, Kenneth A


    For the past 200 years, neurology has been deeply rooted in the history and neurologic examination, but 21st century advances in neurosurgery, endovascular techniques, and neuropathology, and an explosion in basic neuroscience research and neuroimaging have added exciting new dimensions to the field. Neurology residency training programs face intense governmental regulatory changes and economic pressures, making it difficult to predict the number of neurology residents being trained for the future. The future job outlook for neurologists in the United States, based on recent survey and trends, suggests an increased demand because of the prevalence of neurologic diseases within the aging population, particularly in underserved urban and rural areas. Telemedicine and "teleconsultation" offer a potential solution to bringing virtual subspecialists to underserved areas. The future for neurology and neuroscience research in the United States remains a high priority according to the National Institute of Neurologic Diseases and Stroke, but this may be affected in the long run by budgetary constraints and a growing deficit.

    Full Text Available Hashimoto%u2019s encephalopathy (HE is a rare disorder associated with autoimmune thyroiditis. Etiology of HE is not completely understood. High levels of serum antithyroid antibodies are seen in HE. Presentation with otoimmune thyroiditis, cognitive impairment, psychiatric and neurologic symptoms and absence of bacterial or viral enfections are characteristics of HE. HE is a steroid responsive encephalopathy. 60 years old male patient admitted to hospital with forget fulness continuing for 9 months and speech loss starting 2 days ago. Strong positivity of antithyroid antibodies increases the odds for HE. Thyroid function tests showed severe hypothyroidism. Electroencephalography and magnetic resonance imaging results were compatible with HE. HE is diagnosed with differantial diagnosis and exclusion of other reasons. This uncommon disorder is not recognised enough. High titres of serum antithyroid antiboides are always needed for diagnosis. Correct diagnosis requires awareness of wide range of cognitive and clinical presentations of HE.

  19. [Oliver Sacks and literary neurology]. (United States)

    Guardiola, Elena; Banos, Josep E


    Popular medical literature attempts to discuss medical topics using a language that is, as far as possible, free of all medical jargon so as to make it more easily understandable by the general public. The very complexity of neurology makes it more difficult for the stories dealing with this specialty to be understood easily by an audience without any kind of medical training. This paper reviews the works written by Oliver Sacks involving the field of neurology aimed at the general public, and the main characteristics and the clinical situation discussed by the author are presented. Some biographical notes about Oliver Sacks are also included and the 11 books published by this author over the last 40 years are also analysed. In each case they are put into a historical context and the most outstanding aspects justifying what makes them an interesting read are commented on. In most cases, the genesis of the work is explained together with its most significant features. The works of Sacks contain a wide range of very interesting clinical situations that are usually explained by means of a language that is readily comprehensible to the general public. It also provides neurologists with a holistic view of different clinical situations, together with a discussion of their biographical, historical and developmental components.

    Our aim was to evaluate Wikipedia page visits in relation to the most common neurological disorders by determining which factors are related to peaks in Wikipedia searches for these conditions. Millions of people worldwide use the internet daily as a source of health information. Wikipedia is a popular free online encyclopedia used by patients and physicians to search for health-related information. The following Wikipedia articles were considered: Alzheimer's disease; Amyotrophic lateral sclerosis; Dementia; Epilepsy; Epileptic seizure; Migraine; Multiple sclerosis; Parkinson's disease; Stroke; Traumatic brain injury. We analyzed information regarding the total article views for 90 days and the rank of these articles among all those available in Wikipedia. We determined the highest search volume peaks to identify possible relation with online news headlines. No relation between incidence or prevalence of neurological disorders and the search volume for the related articles was found. Seven out of 10 neurological conditions showed relations in search volume peaks and news headlines. Six out of these seven peaks were related to news about famous people suffering from neurological disorders, especially those from showbusiness. Identification of discrepancies between disease burden and health seeking behavior on Wikipedia is useful in the planning of public health campaigns. Celebrities who publicly announce their neurological diagnosis might effectively promote awareness programs, increase public knowledge and reduce stigma related to diagnoses of neurological disorders.

    Thallium-201 (Tl-201) myocardial emission computed tomography and whole body scintigraphy were performed using a rotating gamma camera in 64 patients with neurologic disease and 14 normal subjects. Thallium-201 myocardial perfusion defects were seen in 40 % of the muscular involvement in 47 patients with muscular dystrophy (MD), in whom morphological abnormality of the heart was common. There was strong relationship between the degree of left ventricular perfusion defects and the degree of pulmonary uptake of Tl-201. Thallium-201 whole body scintigraphy showed homogeneous distribution of Tl-201 in the extremities in normal subjects, and perfusion defects in 73 % of the muscular lesions in MD patients. Muscular and skeletal lesions for MD appear to progress independently. Thallium-201 imaging seems to be of clinical value in assessing the muscular and skeletal lesions. (Namekawa, K.)

  3. Neurologic manifestations of achondroplasia. (United States)

    Hecht, Jacqueline T; Bodensteiner, John B; Butler, Ian J


    Achondroplasia is the best described and most common form of the congenital short-limbed dwarfing conditions. Achondroplasia is apparent at birth and has a birth prevalence of 1 in 20000-30000 live-born infants. Achondroplasia is inherited as an autosomal dominant condition, although 80% of cases occur sporadically as new events in their families. Achondroplasia is caused, in virtually all of the cases, by a G380R mutation in fibroblast growth factor receptor 3 (FGFR3). Patients with achondroplasia should be evaluated by a multidisciplinary team of clinicians including geneticists, neurologists, and orthopedists, since there are numerous bony and neurological complications. The most severe complication results from craniocervical stenosis and medullary and upper spinal cord compression, which can have devastating and even lethal sequelae during early childhood. In subsequent decades, including adolescence, spinal cord and nerve compression are more prominent. The neurological complications of achondroplasia have been recognized in adults for more than a century and are attributed to bony defects, connective tissue structures, or both. Similar neurological complications are now appreciated in infants, young children, and teenagers with achondroplasia. Defective connective tissue elements in achondroplasia frequently lead to ligamentous laxity, which can aggravate the complications associated with bony stenosis. Bony abnormalities are known to cause neurological morbidity and lead to a shortened lifespan. Neurological complications associated with achondroplasia are reviewed, including recommendations for the evaluation and management of these clinical problems. © 2014 Elsevier B.V.

  4. Neurology and Don Quixote. (United States)

    Palma, Jose-Alberto; Palma, Fermin


    Don Quixote de la Mancha, which is considered one of the most important and influential works of Western modern prose, contains many references of interest for almost all of the medical specialties. In this regard, numerous references to neurology can be found in Cervantes' immortal work. In this study, we aimed to read Don Quixote from a neurologist's point of view, describing the neurological phenomena scattered throughout the novel, including tremors, sleep disturbances, neuropsychiatric symptoms, dementia, epilepsy, paralysis, stroke, syncope, traumatic head injury, and headache; we relate these symptoms with depictions of those conditions in the medical literature of the time. We also review Cervantes' sources of neurological information, including the works by renowned Spanish authors such as Juan Huarte de San Juan, Dionisio Daza Chacón and Juan Valverde de Amusco, and we hypothesize that Don Quixote's disorder was actually a neurological condition. Although Cervantes wrote it four centuries ago, Don Quixote contains plenty of references to neurology, and many of the ideas and concepts reflected in it are still of interest. Copyright © 2012 S.

  5. [Overcoming neurological diseases-breakthrough for new era]. (United States)

    Mizusawa, Hidehiro


    Neurological diseases have long been thought to be difficult or intractable to be cured. Recent progress in researches on etiologies and pathogeneses of many neurological diseases, however, has made it become possible to treat some diseases such as bulbo-spinal muscular atrophy and Alzheimer's disease not only symptomatically but also in the sense of disease modification. We may be at the entrance of a new era where many neurological diseases would become treatable and overcome. My individual experiences studying 3 diseases, namely, distal myopathy with rimmed vacuoles, amyotrophic lateral sclerosis and spinocerebellar ataxia were presented and through them the following massages were conveyed to young neurologists of the Japanese Society of Neurology (JSN); To tackle the case even there is no similar case in the literature because you are the only one who could help the patient and some clues must be found, To cooperate with other colleagues and patients because you are not alone, To be reasonable, logical or scientific, To always be innovative or seek better situations, and To be global or international sharing real time information with other peoples in the world. JSN will make great leaps to the goals under the mission to contribute happiness of peoples in Japan and other countries through neurology including neurological practice, education and research.

  6. Bed Rest Muscular Atrophy (United States)

    Greenleaf, John E.


    A major debilitating response from prolonged bed rest (BR) is muscle atrophy, defined as a "decrease in size of a part of tissue after full development has been attained: a wasting away of tissue as from disuse, old age, injury or disease". Part of the complicated mechanism for the dizziness, increased body instability, and exaggerated gait in patients who arise immediately after BR may be a result of not only foot pain, but also of muscular atrophy and associated reduction in lower limb strength. Also, there seems to be a close association between muscle atrophy and bone atrophy. A discussion of many facets of the total BR homeostatic syndrome has been published. The old adage that use determines form which promotes function of bone (Wolff's law) also applies to those people exposed to prolonged BR (without exercise training) in whom muscle atrophy is a consistent finding. An extreme case involved a 16-year-old boy who was ordered to bed by his mother in 1932: after 50 years in bed he had "a lily-white frame with limbs as thin as the legs of a ladder-back chair". These findings emphasize the close relationship between muscle atrophy and bone atrophy. In addition to loss of muscle mass during deconditioning, there is a significant loss of muscle strength and a decrease in protein synthesis. Because the decreases in force (strength) are proportionately greater than those in fiber size or muscle cross-sectional area, other contributory factors must be involved; muscle fiber dehydration may be important.

  7. The neurology literature 2016. (United States)

    Khoujah, Danya; Chang, Wan-Tsu W; Abraham, Michael K


    Emergency neurology is a complex and rapidly changing field. Its evolution can be attributed in part to increased imaging options, debates about optimal treatment, and simply the growth of emergency medicine as a specialty. Every year, a number of articles published in emergency medicine or other specialty journals should become familiar to the emergency physician. This review summarizes neurology articles published in 2016, which the authors consider crucial to the practice of emergency medicine. The articles are categorized according to disease process, with the understanding that there can be significant overlap among articles. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. [Nutritional and metabolic aspects of neurological diseases]. (United States)

    Planas Vilà, Mercè


    The central nervous system regulates food intake, homoeostasis of glucose and electrolytes, and starts the sensations of hunger and satiety. Different nutritional factors are involved in the pathogenesis of several neurological diseases. Patients with acute neurological diseases (traumatic brain injury, cerebral vascular accident hemorrhagic or ischemic, spinal cord injuries, and cancer) and chronic neurological diseases (Alzheimer's Disease and other dementias, amyotrophic lateral sclerosis, Parkinson's Disease) increase the risk of malnutrition by multiple factors related to nutrient ingestion, abnormalities in the energy expenditure, changes in eating behavior, gastrointestinal changes, and by side effects of drugs administered. Patients with acute neurological diseases have in common the presence of hyper metabolism and hyper catabolism both associated to a period of prolonged fasting mainly for the frequent gastrointestinal complications, many times as a side effect of drugs administered. During the acute phase, spinal cord injuries presented a reduction in the energy expenditure but an increase in the nitrogen elimination. In order to correct the negative nitrogen balance increase intakes is performed with the result of a hyper alimentation that should be avoided due to the complications resulting. In patients with chronic neurological diseases and in the acute phase of cerebrovascular accident, dysphagia could be present which also affects intakes. Several chronic neurological diseases have also dementia, which lead to alterations in the eating behavior. The presence of malnutrition complicates the clinical evolution, increases muscular atrophy with higher incidence of respiratory failure and less capacity to disphagia recuperation, alters the immune response with higher rate of infections, increases the likelihood of fractures and of pressure ulcers, increases the incapacity degree and is an independent factor to increase mortality.

  11. Neurological aspects of eclampsia

    Directory of Open Access Journals (Sweden)

    Jovanović Dejana


    Full Text Available The difficult types of preeclampsia and eclampsia are presented with the neurological symptoms. The break of cerebral autoregulation mechanism plays the most important role in pathogenesis of cerebral vasospasm. Nevertheless eclampsia isn’t just an ordinary hypertensive encephalopathy because other pathogenic mechanisms are involved in its appearance. The main neuropathologic changes are multifocal vasogenic edema, perivascular multiple microinfarctions and petechial hemorrhages. Neurological clinical manifestations are convulsions, headache, visual disturbances and rarely other discrete focal neurological symptoms. Eclampsia is a high-risk factor for onset of hemorrhagic or ischemic stroke. This is a reason why neurological diagnostic tests are sometimes needed. The method of choice for evaluation of complicated eclampsia is computerized brain topography that shows multiple areas of hypodensity in occipitoparietal regions. These changes are focal vasogenic cerebral edema. For differential diagnosis of eclampsia and stroke other diagnostic methods can be used - fundoscopic exam, magnetic resonance brain imaging, cerebral angiography and cerebrospinal fluid exam. The therapy of eclampsia considers using of magnesium sulfate, antihypertensive, anticonvulsive and antiedematous drugs.

  13. How operating room efficiency is understood in a surgical team: a qualitative study. (United States)

    Arakelian, Erebouni; Gunningberg, Lena; Larsson, Jan


    Building surgical teams is one attempt to ensure the health-care system becomes more efficient, but how is 'efficiency' understood or interpreted? The aim was to study how organized surgical team members and their leaders understood operating room efficiency. Qualitative study. A 1100-bed Swedish university hospital. Eleven participants, nine team members from the same team and their two leaders were interviewed. The analysis was performed according to phenomenography, a research approach that aims to discover variations in peoples' understanding of a phenomenon. Seven ways of understanding operating room efficiency were identified: doing one's best from one's prerequisites, enjoying work and adjusting it to the situation, interacting group performing parallel tasks, working with minimal resources to produce desired results, fast work with preserved quality, long-term effects for patient care and a relative concept. When talking about the quality and benefits of delivered care, most team members invoked the patient as the central focus. Despite seven ways of understanding efficiency between the team members, they described their team as efficient. The nurses and assistant nurses were involved in the production and discussed working in a timely manner more than the leaders. The seven ways of understanding operating room efficiency appear to represent both organization-oriented and individual-oriented understanding of that concept in surgical teams. The patient is in focus and efficiency is understood as maintaining quality of care and measuring benefits of care for the patients.

  14. Neurological diseases and pain (United States)


    Chronic pain is a frequent component of many neurological disorders, affecting 20–40% of patients for many primary neurological diseases. These diseases result from a wide range of pathophysiologies including traumatic injury to the central nervous system, neurodegeneration and neuroinflammation, and exploring the aetiology of pain in these disorders is an opportunity to achieve new insight into pain processing. Whether pain originates in the central or peripheral nervous system, it frequently becomes centralized through maladaptive responses within the central nervous system that can profoundly alter brain systems and thereby behaviour (e.g. depression). Chronic pain should thus be considered a brain disease in which alterations in neural networks affect multiple aspects of brain function, structure and chemistry. The study and treatment of this disease is greatly complicated by the lack of objective measures for either the symptoms or the underlying mechanisms of chronic pain. In pain associated with neurological disease, it is sometimes difficult to obtain even a subjective evaluation of pain, as is the case for patients in a vegetative state or end-stage Alzheimer's disease. It is critical that neurologists become more involved in chronic pain treatment and research (already significant in the fields of migraine and peripheral neuropathies). To achieve this goal, greater efforts are needed to enhance training for neurologists in pain treatment and promote greater interest in the field. This review describes examples of pain in different neurological diseases including primary neurological pain conditions, discusses the therapeutic potential of brain-targeted therapies and highlights the need for objective measures of pain.

    Andersen, H; Gadeberg, P C; Brock, B


    Diabetic patients with polyneuropathy develop motor dysfunction. To establish whether motor dysfunction is associated with muscular atrophy the ankle dorsal and plantar flexors of the non-dominant leg were evaluated with magnetic resonance imaging in 8 patients with symptomatic neuropathy, in 8 non...... confirmed that the atrophy predominated distally. We conclude that muscular atrophy underlies motor weakness at the ankle in diabetic patients with polyneuropathy and that the atrophy is most pronounced in distal muscles of the lower leg indicating that a length dependent neuropathic process explains...

    Anastasia Gkampeta


    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

  1. Neurology and detective writing. (United States)

    Kempster, Peter A; Lees, Andrew J


    When searching for clues to reach a diagnosis, neurologists often empathise with the detective who is trying to solve a case. The premise of this article is that detective stories have been part of the fabric of neurology ever since the time that it evolved into a discrete medical speciality. We will examine how this form of narrative has found expression in detective mystery fiction and popular science publications created by 20th century neurologist physician-writers. We will also investigate the power of the neurologist's alter ego, Sherlock Holmes: his relationship to founders of clinical neuroscience such as Jean-Martin Charcot, William Gowers and Sigmund Freud, and his influences on neurological practice and its literary traditions.

    Radhakrishna H


    Full Text Available Neurological disorders with a prolonged course, either remediable or otherwise are being seen increasingly in clinical practice and many such patients are young and are part of some organization or other wherein their services are needed if they were healthy and fit. The neurologists who are on the panel of these organizations are asked to certify whether these subjects are fit to work or how long they should be given leave. These certificates may be produced in the court of law and may be subjected to verification by another neurologist or a medical board. At present there are no standard guidelines in our country to effect such certification unlike in orthopedic specialty or in ophthalmology. The following is a beginning, based on which the neurologist can certify the neurological disability of such subjects and convey the same meaning to all neurologists across the country.

  3. The Neurology of Proverbs

    Directory of Open Access Journals (Sweden)

    Diana Van Lancker


    Full Text Available Although proverb tests are commonly used in the mental status examination surprisingly little is known about either normal comprehension or the interpretation of proverbial expressions. Current proverbs tests have conceptual and linguistic shortcomings, and few studies have been done to investigate the specific effects of neurological and psychiatric disorders on the interpretation of proverbs. Although frontal lobes have traditionally been impugned in patients who are “concrete”, recent studies targeting deficient comprehension of non literal language (e.g. proverbs, idioms, speech formulas, and indirect requests point to an important role of the right hemisphere (RH. Research describing responses of psychiatrically and neurologically classified groups to tests of proverb and idiom usage is needed to clarify details of aberrant processing of nonliteral meanings. Meanwhile, the proverb test, drawing on diverse cognitive skills, is a nonspecific but sensitive probe of mental status.

    Full Text Available Dengue infection is highly endemic in many tropical countries including Malaysia. However, neurological complications arising from dengue infection is not common; Gullain–Barre syndrome (GBS is one of these infrequent complications. In this paper, we have reported a case in which a 39-year-old woman presented with a neurological complication of dengue infection without typical symptoms and signs of dengue fever. She had a history of acute gastroenteritis (AGE followed by an upper respiratory tract infection (URTI weeks prior to her presentation rendering GBS secondary to the post viral URTI and AGE as the most likely diagnosis. Presence of thrombocytopenia was the only clue for dengue in this case.

  7. Survey of the professors of child neurology: neurology versus pediatrics home for child neurology. (United States)

    Pearl, Phillip L; McConnell, Emily R; Fernandez, Rosamary; Brooks-Kayal, Amy


    The optimal academic home for child neurology programs between adult neurology versus pediatric departments remains an open question. The Professors of Child Neurology, the national organization of child neurology department chairs, division chiefs, and training program directors, was surveyed to evaluate the placement of child neurology programs. Professors of Child Neurology members were surveyed regarding the placement of child neurology programs within adult neurology versus pediatric departments. Questions explored academic versus clinical lines of reporting and factors that may be advantages and disadvantages of these affiliations. Issues also addressed were the current status of board certification and number of clinics expected in academic child neurology departments. Of 120 surveys sent, 95 responses were received (79% response rate). The primary academic affiliation is in neurology in 54% of programs versus 46% in pediatrics, and the primary clinical affiliation is 45% neurology and 55% pediatrics. Advantages versus disadvantages of one's primary affiliation were similar whether the primary affiliation was in neurology or pediatrics. While 61% of respondents are presently board certified in pediatrics, only 2% of those with time-limited certification in general pediatrics plan to be recertified going forward. Typically six to eight half-day clinics per week are anticipated for child neurologists in academic departments without additional funding sources. Overall, leaders of child neurology departments and training programs would not change their affiliation if given the opportunity. Advantages and disadvantages associated with current affiliations did not change whether child neurology was located in neurology or pediatrics. Board certification by the American Board of Psychiatry and Neurology in child neurology is virtually universal, whereas pediatric board certification by the American Board of Pediatrics is being maintained by very few.

  8. Palliative care and neurology (United States)

    Boersma, Isabel; Miyasaki, Janis; Kutner, Jean


    Palliative care is an approach to the care of patients and families facing progressive and chronic illnesses that focuses on the relief of suffering due to physical symptoms, psychosocial issues, and spiritual distress. As neurologists care for patients with chronic, progressive, life-limiting, and disabling conditions, it is important that they understand and learn to apply the principles of palliative medicine. In this article, we aim to provide a practical starting point in palliative medicine for neurologists by answering the following questions: (1) What is palliative care and what is hospice care? (2) What are the palliative care needs of neurology patients? (3) Do neurology patients have unique palliative care needs? and (4) How can palliative care be integrated into neurology practice? We cover several fundamental palliative care skills relevant to neurologists, including communication of bad news, symptom assessment and management, advance care planning, caregiver assessment, and appropriate referral to hospice and other palliative care services. We conclude by suggesting areas for future educational efforts and research. PMID:24991027

  9. Perioperative complications of scoliosis surgery in patients with Duchenne muscular dystrophy and spinal muscular atrophy, focussing on wound healing disorders. (United States)

    Burow, Mareike; Forst, Raimund; Forst, Jürgen; Hofner, Benjamin; Fujak, Albert


    Patients with Duchenne muscular dystrophy (DMD) or spinal muscular atrophy (SMA), both neuromuscular diseases, sustain spinal scoliosis in the course of their disease. To reduce the concomitant major morbidity and to improve their quality of life, patients require surgical spine stabilization. This can lead to complications like respiratory, cardiac or neurological complications or wound healing disorders (WHD). To find out the different complexities and risk factors increasing the chance to develop a WHD, the inpatient database was analyzed. We performed a retrospective statistical study. Therefore, we analyzed the inpatient database of 180 patients (142 DMD and 38 SMA patients). The focus was on WHD. To figure out the risk factors leading to WHD, we conducted a logistic regression. Cardiac complications occurred most frequently, followed by pulmonary complications and neurological lesions. Fifty-seven out of 180 patients developed a WHD. In 23 cases the WHD was aseptic, in the other 34 cases dermal organisms, Pseudomonas species and intestinal organisms were responsible. By means of the logistic regression, we were able to identify two more risk factors, in addition to diagnosis and gender, for developing a WHD in our patients: the year of surgery and the direction of pelvic tilt. Most common complications following scoliosis surgery are respiratory and cardiac complications. WHD is a severe complication that implies a prolonged therapy. Some risk factors for developing WHD could be identified in this analysis. Specifically, these were the date of surgery and the direction of pelvic tilt.

    Neurological injury resulting from cardiac surgery has a range of manifestations from focal neurological deficit to encephalopathy or coma. As the safety of drug-eluting stents comes into question, more patients will likely undergo coronary artery bypass graft surgery. These projections, along with the growing proportions of elderly patients and those with comorbidities, portend the potential for rising rates of perioperative neurological complications. The risk for neurological injury may be...

    The aim of this collaborative study on Duchenne muscular dystrophy and Becker muscular dystrophy is to determine the prevalence and to develop data on such patients as a prelude to the development of registry in Hong Kong. Information on clinical and molecular findings, and patient care, was systematically collected in 2011 and 2012 from all Pediatric Neurology Units in Hong Kong. Ninety patients with dystrophinopathy were identified, and 83% has Duchenne muscular dystrophy. The overall prevalence of dystrophinopathy in Hong Kong in 2010 is 1.03 per 10 000 males aged 0 to 24 years. Among the Duchenne group, we observed a higher percentage (40.6%) of point mutations with a lower percentage (45.3%) of exon deletions in our patients when compared with overseas studies. Although we observed similar percentage of Duchenne group received scoliosis surgery, ventilation support, and cardiac treatment when compared with other countries, the percentage (25%) of steroid use is lower.

  15. Congenital Vomer Agenesis: A Rare and Poorly Understood Condition Revealed by Cone Beam CT. (United States)

    Yan, David Jun; Lenoir, Vincent; Chatelain, Sibylle; Stefanelli, Salvatore; Becker, Minerva


    Isolated congenital vomer agenesis is a very rare and poorly understood condition. In the context of dental work-up by cone-beam computed tomography (CBCT), the explored volume of the facial bones occasionally reveals incidental abnormalities. We report the case of a 13-year old Caucasian female who underwent CBCT for the pre-treatment evaluation of primary failure of tooth eruption affecting the permanent right upper and inferior molars. CBCT depicted a large defect of the postero-inferior part of the nasal septum without associated soft tissue abnormality and without cranio-facial malformation or cleft palate. In the absence of a history of trauma, chronic inflammatory sinonasal disease, neoplasia and drug abuse, a posterior nasal septum defect warrants the diagnosis of vomer agenesis. A discussion of this condition and of salient CBCT features is provided.

  16. Poorly understood and often miscategorized congenital umbilical cord hernia: an alternative repair method. (United States)

    İnce, E; Temiz, A; Ezer, S S; Gezer, H Ö; Hiçsönmez, A


    Umbilical cord hernia is poorly understood and often miscategorized as "omphalocele minor". Careless clamping of the cord leads to iatrogenic gut injury in the situation of umbilical cord hernia. This study aimed to determine the characteristics and outcomes of umbilical cord hernias. We also highlight an alternative repair method for umbilical cord hernias. We recorded 15 cases of umbilical cord hernias over 10 years. The patients' data were retrospectively reviewed, and preoperative preparation of the newborn, gestational age, birth weight, other associated malformations, surgical technique used, enteral nutrition, and length of hospitalization were recorded. This study included 15 neonates with umbilical cord hernias. The mean gestational age at the time of referral was 38.2 ± 2.1 umbilical cord hernia, the body folds develop normally and form the umbilical ring. The double purse-string technique is easy to apply and produces satisfactory cosmetic results in neonates with umbilical cord hernias.

  17. Cyclosporine increases muscular force generation in Duchenne muscular dystrophy. (United States)

    Sharma, K R; Mynhier, M A; Miller, R G


    We investigated the effect of cyclosporine (CsA) on force generation in 15 boys with Duchenne muscular dystrophy (DMD) by obtaining monthly measures of tetanic force and maximum voluntary contraction (MVC) of both anterior tibial muscles. During 4 months of a natural history phase, both tetanic force and MVC declined significantly. During 8 weeks of CsA treatment (5 mg/kg/day), significantly increased tetanic force (25.8 +/- 6.6%) and MVC (13.6 +/- 4.0%) occurred within 2 weeks. The maximum mean increase during treatment was 35.2 +/- 5.9% (tetanic force) and 19.0 +/- 4.6% (MVC). Side effects from CsA, gastrointestinal and flu-like symptoms, were transient and self-limiting. Thus, as previously reported with prednisone, CsA increases muscular force generation in the anterior tibial muscles of DMD patients.

  18. Neurology and literature 2. (United States)

    Iniesta, I


    Good literary fiction has the potential to move us, extend our sense of life, transform our prospective views and help us in the face of adversity. A neurological disorder is likely to be the most challenging experience a human being may have to confront in a lifetime. As such, literary recreations of illnesses have a doubly powerful effect. Study the synergies between neurology and fictional literature with particular reference to narrative based medicine (NBM). Doctors establish boundaries between the normal and the abnormal. Taking a clinical history is an act of interpretation in which the doctor integrates the science of objective signs and measurable quantities with the art of subjective clinical judgment. The more discrepancy there is between the patient's experience with the illness and the doctor's interpretation of that disease, the less likely the doctor-patient interaction is to succeed. NBM contributes to a better discernment of the meanings, thus considering disease as a biographical event rather than just a natural fact. Drawing from their own experience with disease, writers of fiction provide universal insights through their narratives, whilst neuroscientists, like Cajal, have occasionally devoted their scientific knowledge to literary narratives. Furthermore, neurologists from Alzheimer to Oliver Sacks remind us of the essential value of NBM in the clinic. Integrating NBM (the narrative of patients) and the classic holistic approach to patients with our current paradigm of evidence based medicine represents a challenge as relevant to neurologists as keeping up with technological and scientific advances.

    Girija A


    Full Text Available Aim: To assess the neurological complications of chickenpox with prognosis. Background: The neurological complications occur in 0.03% of persons who get chickenpox. There is no universal vaccination against chicken pox in India. Most patients prefer alternate modalities of treatment. Hence these complications of chickenpox are likely to continue to occur. Study Design: A prospective study was conducted for 2 years (from March 2002 on the admitted cases with neurological complications after chickenpox (with rash or scar. Patients were investigated with CT/MRI, CSF study, EEG and nerve conduction studies and hematological workup. They were followed-up for 1 year and outcome assessed using modified Rankin scale. Results: The latency for the neurological complications was 4-32 days (mean: 16.32 days. There were 18 cases: 10 adults (64% and 8 children (36%. Cerebellar ataxia (normal CT/MRI was observed in 7 cases (32% (mean age: 6.85 years. One patient (6 years had acute right hemiparesis in the fifth week due to left capsular infarct. All these cases spontaneously recovered by 4 weeks. The age range of the adult patients was 13-47 years (mean: 27 years. The manifestations included cerebellar and pyramidal signs (n-4 with features of demyelination in MRI who recovered spontaneously or with methylprednisolone by 8 weeks.

    Pires, A M; Reis, A G; Grisi, S J


    Symptoms of psoas muscular abscess in children are nonspecific and differential diagnosis is made among diseases included in childreńs acute hip pain syndrome, imaging tests being necessary for diagnostic confirmation. During the first semester of 1995, 48,550 children were examined in Pronto Socorro do Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, four of them diagnosed as having psoas muscular abscess (2 females and 2 males, ages varying from 1 to 12 years). All of them had nonspecific clinical features and diagnosis was confirmed by abdominal ultrasound and/or computerized tomography. Staphylococcus aureus was isolated as the etiologic agent in 3 children, findings similar to the ones in literature.

  1. CT findings of muscular dystrophy

    International Nuclear Information System (INIS)

    Saitoh, Hiroshi


    CT scans of muscles in patients with limb girdle type (LG), myotonic type (MYD) and Duchenne type (DMD) dystrophies were obtained at five different body levels: the neck, L3 vertebral body, pelvic girdle, thigh and lower leg. CT numbers, cross sectional areas (CSA) and %CSA of muscle or fat were evaluated in each muscle. The characteristic CT patterns for each type of muscular dystrophy were obtained. Compared with DMD, the gracilis and soleus were more severely damaged in LG and the biceps femoris remained relatively preserved among the hamstrings. In addition, the multifidus of the neck and sternocleidomastoid also were more severely damaged in MYD. This study suggests that CT scan will be useful in the differential diagnosis of these types of muscular dystrophy as well as in planning appropriate rehabilitation and detecting damaged muscles.

  2. Testing biochemistry revisited: how in vivo metabolism can be understood from in vitro enzyme kinetics.

    Directory of Open Access Journals (Sweden)

    Karen van Eunen

    Full Text Available A decade ago, a team of biochemists including two of us, modeled yeast glycolysis and showed that one of the most studied biochemical pathways could not be quite understood in terms of the kinetic properties of the constituent enzymes as measured in cell extract. Moreover, when the same model was later applied to different experimental steady-state conditions, it often exhibited unrestrained metabolite accumulation.Here we resolve this issue by showing that the results of such ab initio modeling are improved substantially by (i including appropriate allosteric regulation and (ii measuring the enzyme kinetic parameters under conditions that resemble the intracellular environment. The following modifications proved crucial: (i implementation of allosteric regulation of hexokinase and pyruvate kinase, (ii implementation of V(max values measured under conditions that resembled the yeast cytosol, and (iii redetermination of the kinetic parameters of glyceraldehyde-3-phosphate dehydrogenase under physiological conditions.Model predictions and experiments were compared under five different conditions of yeast growth and starvation. When either the original model was used (which lacked important allosteric regulation, or the enzyme parameters were measured under conditions that were, as usual, optimal for high enzyme activity, fructose 1,6-bisphosphate and some other glycolytic intermediates tended to accumulate to unrealistically high concentrations. Combining all adjustments yielded an accurate correspondence between model and experiments for all five steady-state and dynamic conditions. This enhances our understanding of in vivo metabolism in terms of in vitro biochemistry.

  3. The market of human organs: a window into a poorly understood global business. (United States)

    Surman, O S; Saidi, R; Purtilo, R; Simmerling, M; Ko, D; Burke, T F


    The global demand for human organs has set the stage for an exploding and poorly understood global business in human organs. Whenever there is demand for a product, the opportunity for business arises. The form that a business takes is dependent on a complex network of inputs and outputs, each affecting the others. Historically, the details of any specific market are drastically underestimated. Nowhere is this truer than in the market of human organs. The drivers, which propel the "goods" of human organs, form a flourishing business. Critical analysis is essential to understanding of the supply and demand sides and to determine the role of government in regulating the industry. Governmental groups have dismissed formation of a regulated market for organ sales. The concept is nonetheless a topic of active discussion, motivated by the suffering of patients in need of organs and exploitation of the victims of human trafficking. Ethical principles have been invoked on each side of the ensuing debate. Theory in the absence of sufficient data is shaky ground for enactment of new policy. The Aristotelian concept of "practical wisdom" and the pragmatism of William James illuminate the importance of scientific investigation as guide to policy formation. How will stakeholders benefit or lose? What impact might be anticipated in regard to organized medicine's social contract? What can we learn about cross-cultural differences and their effect on the global landscape?

  4. How spirituality is understood and taught in New Zealand medical schools. (United States)

    Lambie, D; Egan, R; Walker, S; MacLeod, R


    The objective of this research was to explore how spirituality is currently understood and taught in New Zealand Medical Schools. A mixed methods study was carried out involving interviews (n = 14) and a survey (n = 73). The first stage of the study involved recorded semi-structured interviews of people involved in curriculum development from the Dunedin School of Medicine (n = 14); which then informed a cross-sectional self-reported electronic survey (n = 73). The results indicate that spirituality is regarded by many involved in medical education in New Zealand as an important part of healthcare that may be taught in medical schools, but also that there is little consensus among this group as to what the topic is about. These findings provide a basis for further discussion about including spirituality in medical curricula, and in particular indicate a need to develop a shared understanding of what 'spirituality' means and how it can be taught appropriately. As a highly secular country, these New Zealand findings are significant for medical education in other secular Western countries. Addressing spirituality with patients has been shown to positively impact a range of health outcomes, but how spirituality is taught in medical schools is still developing across the globe.

    Constituents of the Cannabis plant, cannabinoids, may be of therapeutic value in neurologic diseases. The most abundant cannabinoids are Δ(9)-tetrahydrocannabinol, which possesses psychoactive properties, and cannabidiol, which has no intrinsic psychoactive effects, but exhibits neuroprotective properties in preclinical studies. A small number of high-quality clinical trials support the safety and efficacy of cannabinoids for treatment of spasticity of multiple sclerosis, pain refractory to opioids, glaucoma, nausea and vomiting. Lower level clinical evidence indicates that cannabinoids may be useful for dystonia, tics, tremors, epilepsy, migraine and weight loss. Data are also limited in regards to adverse events and safety. Common nonspecific adverse events are similar to those of other CNS 'depressants' and include weakness, mood changes and dizziness. Cannabinoids can have cardiovascular adverse events and, when smoked chronically, may affect pulmonary function. Fatalities are rare even with recreational use. There is a concern about psychological dependence, but physical dependence is less well documented. Cannabis preparations may presently offer an option for compassionate use in severe neurologic diseases, but at this point, only when standard-of-care therapy is ineffective. As more high-quality clinical data are gathered, the therapeutic application of cannabinoids will likely expand.

    The neonatal asphyxia is recognized as an important cause of morbidity and mortality during the pediatric age. The objective of this study was to evaluate the correlation between some neonatal variables and neurological outcome at two years of life in infants with asphyxia, in order to produce a correct prognosis and to grant a rapid and targeted therapy. We have recruited 63 patients whose history and neuroimages suggested a neonatal asphyxia, and we have analysed their clinical- instrumental parameters every three months until two years of life. A correlation study was carried out in order to find a statistical significance indicated by p-value Neonatal seizures are not related to an increased risk to develop epilepsy. Epilepsy alone is a rare event and it usually complicates CP picture. Most subject with both epilepsy and CP are term infants with adequate weight. Preterm VLBW infants have a greater risk to develop a psychomotor delay. Clinical conditions at birth are related to CP severity (several neonatal neurological signs are the greater risk factors). Severely pathological neonatal EEG (background activity) is related to CP severity and an early symptomatic epilepsy onset is related with both epilepsy and CP severity.

  7. The vulnerability of family caregivers in relation to vulnerability as understood by nurses. (United States)

    Sarvimäki, Anneli; Stenbock-Hult, Bettina; Sundell, Eija; Oesch-Börman, Christine


    In Finland, the care of older persons is shifting from institutional care to family care. Research shows that family caregivers experience their situation much in the same way as professional nurses. The nurses' experiences have been studied in terms of vulnerability, and the same perspective could deepen our understanding of family caregivers' experiences. The aim of this study was to gain knowledge of the vulnerability of older caregivers taking care of an ageing family member. The research questions were as follows: How do family caregivers experience vulnerability? How do their experiences relate to vulnerability as understood by nurses? The study was done as a secondary analysis of focus group interviews on the experiences and daily life of older family caregivers. Four caregivers had taken part in monthly interviews during a period of 10 months. The interviews were analysed by deductive and inductive content analysis. The results showed that the caregivers saw caregiving as part of being human. They experienced a variety of feelings and moral agony and were harmed physically, mentally and socially. They showed courage, protected themselves and recognised that being a caregiver also was a source of maturing and developing. These results corresponded with the nurses' understanding of vulnerability. Shame, the experience of duty as a burden, worry and loneliness were themes that were found only among the family caregivers. The use of a matrix may have restricted the analysis, but using it in an unconstrained way allowed for new themes to be created. The results indicate a common humanness and vulnerability in professional and family caregiving. They also show that family caregivers need more support both from society and professionals. © 2016 Nordic College of Caring Science.

  8. Primary care perceptions of neurology and neurology services. (United States)

    Loftus, Angela M; Wade, Carrie; McCarron, Mark O


    Neurophobia (fear of neural sciences) and evaluation of independent sector contracts in neurology have seldom been examined among general practitioners (GPs). A questionnaire determined GPs' perceptions of neurology compared with other medical specialties. GP experiences of neurology services with independent sector companies and the local National Health Service (NHS) were compared. Areas of potential improvement in NHS neurology services were recorded from thematic analyses. Among 76 GPs neurology was perceived to be as interesting as other medical specialties. GPs reported less knowledge, more difficulty and less confidence in neurology compared with other medical specialties. There was a preference for a local NHS neurology service (pneurology services provided better patient satisfaction. GPs prefer local NHS neurology services to independent sector contracts. GPs' evaluations should inform commissioning of neurology services. Combating neurophobia should be an integral part of responsive commissioning. Published by the BMJ Publishing Group Limited.

  9. Angioedema in progressive muscular dystrophy: a case report. (United States)

    Dermendzhiev, Svetlan M; Simeonova, Radostina; Murdjeva, Marianna A


    Systemic allergic reactions, which include angioedema, are very common in clinical practice. There is great diversity in the etiological factors known to trigger angioedema, and in the pathogenetic mechanisms defining this condition. Beside the broad spectrum of immuno-allergic reactions involved in the angioedemic pathogenesis, this condition is known to also develop on the background of other disorders. These disorders may be of different etiology and have different pathogenesis (either non-immune or immune) but have one common feature referred to as "serological overlap". From research and clinical perspective, it is interesting to explore the combination of some rare neurological diseases, such as myopathies and in particular muscular dystrophies with systemic allergic reactions such as angioedema, urticaria and others. It is known that progressive muscular dystrophies (PMD) are hereditary diseases with different types of inheritance--X-chromosome recessive, X-chromosome dominant, autosomal dominant and others. In some forms, such as Duchenne muscular dystrophy (DMD), an increased expression of perforin in muscle is found which is evidence for involvement of the cellular immune response in the pathogenesis of myopathy. It is in this sense that it is interesting to explore and discuss a clinical case diagnosed as a facioscapulohumeral form of PMD, which also manifests angioedema with urticaria. We present a 41-year-old male hospitalized in the Division of Occupational Diseases and Allergology at St. George University Hospital in Plovdiv who suffered two incidents of massive angioedema on the face, back and chest, accompanied by an itchy urticarial rash. In 1985, after hospitalization to the Clinic of Neurology, he was diagnosed with PMD of facioscapulohumeral type. The medical history could not reveal any of the most common etiologic factors such as drugs, food, insects and other allergens that may be associated with the systemic allergic reactions. The

  10. Pediatric neurology and neuroradiology

    International Nuclear Information System (INIS)

    Diebler, C.


    In this book, a neuroradiologist and a neuropediatrician have combined forces to provide the widest possible knowledge in investigating cranial and cerebral disorders in infancy and childhood. Based on more than 20,000 pediatric CT examinations, with a follow-up time often exceeding ten years, the book aims to bridge interdisciplinary gaps and help radiologists, pediatricians and neurosurgeons solve the various problems of pediatric neuroradiology that frequently confront them. For each disease, the etiology, clinical manifestations, pathological lesions and radiological presentations are discussed, supported by extensive illustrations. Malformative, vascular, traumatic, tumoral, infectious and metabolic diseases are reviewed. Miscellaneous conditions presenting particular symptoms or syndromes are also studied, such as hydrocephalus and neurological complications of leukemia. The combined expertise and experience contained in this volume make it an outstanding reference work in the field of pediatric neuroradiology. (orig./MG)

  11. Consciousness: A Neurological Perspective

    Directory of Open Access Journals (Sweden)

    Andrea E. Cavanna


    Full Text Available Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.

  12. Dismantling Limb-Girdle Muscular Dystrophy


    Narayanaswami, Pushpa


    Muscular dystrophy encompasses a diverse group of genetically determined muscle disorders. The first clinical description of the disorder is attributed to Giovanni Semmola, who, in 1829, described 2 boys affected by a disorder with prominent muscular hypertrophy.1 Between 1850 and 1868, Aran, Meryon, and Duchenne described a progressive atrophy of voluntary muscles, ultimately termed pseudohypertrophic muscular paralysis of children by Duchenne.1,2 Other descriptions followed: familial atroph...

  13. Neurology of ciguatera (United States)

    Pearn, J


    Ciguatera is a widespread ichthyosarcotoxaemia with dramatic and clinically important neurological features. This severe form of fish poisoning may present with either acute or chronic intoxication syndromes and constitutes a global health problem. Ciguatera poisoning is little known in temperate countries as a potentially global problem associated with human ingestion of large carnivorous fish that harbour the bioaccumulated ciguatoxins of the photosynthetic dinoflagellate Gambierdiscus toxicus. This neurotoxin is stored in the viscera of fish that have eaten the dinoflagellate and concentrated it upwards throughout the food chain towards progressively larger species, including humans. Ciguatoxin accumulates in all fish tissues, especially the liver and viscera, of "at risk" species. Both Pacific (P-CTX-1) and Caribbean (C-CTX-1) ciguatoxins are heat stable polyether toxins and pose a health risk at concentrations above 0.1 ppb. The presenting signs of ciguatera are primarily neurotoxic in more than 80% of cases. Such include the pathognomonic features of postingestion paraesthesiae, dysaesthesiae, and heightened nociperception. Other sensory abnormalities include the subjective features of metallic taste, pruritis, arthralgia, myalgia, and dental pain. Cerebellar dysfunction, sometimes diphasic, and weakness due to both neuropathy and polymyositis may be encountered. Autonomic dysfunction leads to hypotension, bradycardia, and hypersalivation in severe cases. Ciguatoxins are potent, lipophilic sodium channel activator toxins which bind to the voltage sensitive (site 5) sodium channel on the cell membranes of all excitable tissues. Treatment depends on early diagnosis and the early administration of intravenous mannitol. The early identification of the neurological features in sentinel patients has the potential to reduce the number of secondary cases in cluster outbreaks.


  14. History of neurologic examination books. (United States)

    Boes, Christopher J


    The objective of this study was to create an annotated list of textbooks dedicated to teaching the neurologic examination. Monographs focused primarily on the complete neurologic examination published prior to 1960 were reviewed. This analysis was limited to books with the word "examination" in the title, with exceptions for the texts of Robert Wartenberg and Gordon Holmes. Ten manuals met the criteria. Works dedicated primarily to the neurologic examination without a major emphasis on disease description or treatment first appeared in the early 1900s. Georg Monrad-Krohn's "Blue Book of Neurology" ("Blue Bible") was the earliest success. These treatises served the important purpose of educating trainees on proper neurologic examination technique. They could make a reputation and be profitable for the author (Monrad-Krohn), highlight how neurology was practiced at individual institutions (McKendree, Denny-Brown, Holmes, DeJong, Mayo Clinic authors), and honor retiring mentors (Mayo Clinic authors).

  17. Perioperative Management of Neurological Conditions

    Directory of Open Access Journals (Sweden)

    Manjeet Singh Dhallu


    Full Text Available Perioperative care of the patients with neurological diseases can be challenging. Most important consideration is the management and understanding of pathophysiology of these disorders and evaluation of new neurological changes that occur perioperatively. Perioperative generally refers to 3 phases of surgery: preoperative, intraoperative, and postoperative. We have tried to address few commonly encountered neurological conditions in clinical practice, such as delirium, stroke, epilepsy, myasthenia gravis, and Parkinson disease. In this article, we emphasize on early diagnosis and management strategies of neurological disorders in the perioperative period to minimize morbidity and mortality of patients.

  18. Education Research: Neurology resident education: Trending skills, confidence, and professional preparation. (United States)

    Jordan, Justin T; Mayans, David; Schneider, Logan; Adams, Nellie; Khawaja, Ayaz M; Engstrom, John


    To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. © 2016 American Academy of Neurology.

  2. [History of neurology and education on neurology in Japan]. (United States)

    Kuzuhara, Shigeki


    The first medical society of Japanese neurologists and psychiatrists was founded in 1902, but psychiatrists gradually dominated in number. New "Japanese Society of Neurology" (JSN) was founded in 1960. The number of members was only 643 in 1960, while it rose up to 8,555 in 2009, including regular, junior, senior and associate members. JSN contributed much to solve the causes and treatment of the medicosocial and iatrogenic diseases such as Minamata disease and SMON (subacute myelopticoneuropathy) at its early period. In undergraduate education at medical school neurology is one of the core subjects in the curriculum, and almost all the 80 medical schools have at least one faculty neurologist. The Board of neurology of JSN was started in 1975, as the third earliest of the Japanese Medical Associations. It takes at least 6 years' clinical training after graduating from the medical school to take the neurology Board examinations. By 2009, 4,000 members passed the Board examinations. In 2002 JSN published evidence-based "Treatment Guidelines 2002" of 6 diseases: Parkinson's disease, stroke, chronic headache, dementia and ALS. As to the international issues, JSN hosted the 12th World Congress of Neurology in 1981, and international activities markedly increased after that. The first informal meeting with JSN and Korean Neurological Association (KNA) was held at the 48th JSN Annual Meeting in Nagoya in May 2007. In May 2008 the KNA-JSN 1st Joint symposium was held at the 49th Annual Meeting of JSN in Yokohama on "International comparison of neurological disorders: focusing on spinocerebellar atrophies (SCA) and epilepsies". In May 2009, KNA-JNS 2 nd Joint Symposium was held at the 50th JSN Annual Meeting in Sendai, inviting a speaker from Taiwan Neurological Society, on the subject "History and Education of Neurology in Japan, Korea and Taiwan". In this symposium, a strategy to make up the Northeast Asian Neurological Association was discussed.

  3. [Music and neurology]. (United States)

    Arias Gómez, M


    Music perception and output are special functions of the human brain. Investigation in this field is growing with the support of modern neuroimaging techniques (functional magnetic resonance imaging, positron emission tomography). Interest in the music phenomenon and the disorders regarding its processing has been limited. Music is not just an artistic activity but a language to communicate, evoke and reinforce several emotions. Although the subject is still under debate, processing of music is independent of common language and each one uses independent circuits. One may be seriously affected and the other practically unharmed. On the other hand, there may be separate channels within the processing of music for the temporary elements (rhythm), melodic elements (pitch, timbre, and melody), memory and emotional response. The study of subjects with absolute pitch, congenital and acquired amusias, musicogenic epilepsy and musical hallucinations has greatly contributed to the knowledge of how the brain processes music. Music training involves some changes in morphology and physiology of professional musicians' brains. Stress, chronic pain and professional dystonias constitute a special field of musicians' disturbances that concerns neurological practice. Listening to and playing music may have some educational and therapeutic benefits.

  4. [Neurological interpretation of dreams] . (United States)

    Pareja, J A; Gil-Nagel, A


    Cerebral cortical activity is constant throughout the entire human life, but substantially changes during the different phases of the sleep-wake cycle (wakefulness, non-REM sleep and REM sleep), as well as in relation to available information. In particular, perception of the environment is closely linked to the wake-state, while during sleep perception turns to the internal domain or endogenous cerebral activity. External and internal information are mutually exclusive. During wakefulness a neuronal mechanism allows attention to focus on the environment whereas endogenous cortical activity is ignored. The opposite process is provided during sleep. The function external attention-internal attention is coupled with the two modes of brain function during wakefulness and during sleep, providing two possible cortical status: thinking and dreaming. Several neurological processes may influence the declaration of the three states of being or may modify their orderly oscillation through the sleep-wake cycle. In addition, endogenous information and its perception (dreams) may be modified. Disturbances of dreaming may configurate in different general clinical scenarios: lack of dreaming, excess of dreaming (epic dreaming), paroxysmal dreaming (epileptic), nightmares, violent dreaming, daytime-dreaming (hallucinations), and lucid dreaming. Sensorial deprivation, as well as the emergence of internal perception may be the underlying mechanism of hallucinations. The probable isomorphism between hallucinations and dreaming is postulated, analyzed and discussed.

  5. Neurologic manifestations of malabsorption syndromes. (United States)

    Pfeiffer, Ronald F


    Although malabsorption is generally considered to be a gastrointestinal problem, the effects of malabsorption extend far beyond the gastrointestinal tract and can include neurologic dysfunction. Malabsorption may occur by a variety of mechanisms, both genetic and acquired, that interfere with the absorption of basic nutrients, vitamins, minerals, and trace elements. Disorders that interfere with fat absorption can lead to neurologic dysfunction as a consequence of associated impairment of fat-soluble vitamin absorption. Thus, individuals with genetic vitamin E deficiency and the familial hypocholesterolemias may develop symptoms of peripheral neuropathy, cerebellar ataxia, and other neurologic signs and symptoms. Disease processes that damage the enteric mucosa and produce malabsorption can trigger neurologic dysfunction both by immune-related processes, as in celiac disease, and by impairing absorption of essential vitamins and other nutrients, as in tropical sprue. Deficiencies of water-soluble vitamins, such as thiamine and niacin, can also develop in the setting of malabsorption and lead to neurologic dysfunction. Neurologists are aware of the neurologic damage that copper excess can cause in Wilson's disease, but copper deficiency due to malabsorption can also produce neurologic dysfunction in the form of myelopathy. It is vitally important for neurologists to be aware of the potential for malabsorptive processes to produce neurologic dysfunction, because effective treatment for such disorders is often available. © 2014 Elsevier B.V.

  7. Neurology Research in Saudi Arabia (United States)

    Algahtani, Hussein; Shirah, Bader; Boker, Faisal; Algamdi, Albaraa; Alkahtani, Abdulah


    Objectives Research activities in Saudi Arabia are promoted at the governmental and institutional levels. However, the output and quality of research conducted in the field of neurology has not yet been measured quantitatively. This study therefore aimed to analyse neurology-related publications from Saudi Arabia. Methods This study was conducted in January 2016. A systematic search using the PubMed® search engine (National Library of Medicine, Bethesda, Maryland, USA) was conducted to identify all neurology-related articles published from Saudi Arabia between January 1996 and December 2015. Results A total of 1,292 neurology-related publications were identified. Neurology research increased linearly with time, with most publications originating from Riyadh (67%) and the university sector (≈47%). However, most neurology-related articles were published in journals which had an impact factor of <1 (55%). Conclusion Neurology research in Saudi Arabia has increased substantially over the last 20 years. However, as most articles were published in low-impact journals, the quality of research remains inadequate and should be improved. It is important that an official research culture be established in both governmental and private universities as well as colleges and health institutions in Saudi Arabia. The formation of clinical academic departments staffed by research experts is recommended to ensure the quality of neurology research output. PMID:29062556

    Sarna, Justyna R; Furtado, Sarah; Brownell, A Keith W


    Metronidazole (Flagyl®) is an antimicrobial agent commonly used in clinical practice. Although it is generally well tolerated with minimal side effects, there are a host of still under-recognized neurologic complications of metronidazole treatment. The following review is aimed at summarizing current literature pertaining to metronidazole-induced neurotoxicity including clinical syndromes, neuroradiological findings, prognosis and proposed pathophysiology. Recognition of the neurotoxic effects of metronidazole is critical as prompt discontinuation is generally associated with full clinical recovery and radiological resolution. Complications neurologiques du métronidazole. Le métronidazole (Flagyl®) est un agent antimicrobien utilisé couramment en pratique clinique. Bien qu'il soit généralement bien toléré et que ses effets secondaires soient minimes, il existe une myriade de complications neurologiques du traitement par le métronidazole qui ne sont pas toujours reconnues. Le but de cette revue constitue un sommaire de la littérature actuelle concernant la neurotoxicité induite par le métronidazole dont les syndromes cliniques, les constatations neuroradiologiques, le pronostic et l'hypothèse physiopathologique expliquant cette neurotoxicité. Il est important d'identifier ces effets neurotoxiques du métronidazole étant donné que l'arrět immédiat du traitement est généralement associé à une guérison clinique complète et à la disparition des signes radiologiques.

  10. Physiology of respiratory disturbances in muscular dystrophies. (United States)

    Lo Mauro, Antonella; Aliverti, Andrea


    Muscular dystrophy is a group of inherited myopathies characterised by progressive skeletal muscle wasting, including of the respiratory muscles. Respiratory failure, i.e . when the respiratory system fails in its gas exchange functions, is a common feature in muscular dystrophy, being the main cause of death, and it is a consequence of lung failure, pump failure or a combination of the two. The former is due to recurrent aspiration, the latter to progressive weakness of respiratory muscles and an increase in the load against which they must contract. In fact, both the resistive and elastic components of the work of breathing increase due to airway obstruction and chest wall and lung stiffening, respectively. The respiratory disturbances in muscular dystrophy are restrictive pulmonary function, hypoventilation, altered thoracoabdominal pattern, hypercapnia, dyspnoea, impaired regulation of breathing, inefficient cough and sleep disordered breathing. They can be present at different rates according to the type of muscular dystrophy and its progression, leading to different onset of each symptom, prognosis and degree of respiratory involvement. A common feature of muscular dystrophy is respiratory failure, i.e. the inability of the respiratory system to provide proper oxygenation and carbon dioxide elimination.In the lung, respiratory failure is caused by recurrent aspiration, and leads to hypoxaemia and hypercarbia.Ventilatory failure in muscular dystrophy is caused by increased respiratory load and respiratory muscles weakness.Respiratory load increases in muscular dystrophy because scoliosis makes chest wall compliance decrease, atelectasis and fibrosis make lung compliance decrease, and airway obstruction makes airway resistance increase.The consequences of respiratory pump failure are restrictive pulmonary function, hypoventilation, altered thoracoabdominal pattern, hypercapnia, dyspnoea, impaired regulation of breathing, inefficient cough and sleep disordered

  11. Pedometer step counts in individuals with neurological conditions. (United States)

    Elsworth, Charlotte; Dawes, Helen; Winward, Charlotte; Howells, Ken; Collett, Johnny; Dennis, Andrea; Sackley, Catherine; Wade, Derick


    To examine the accuracy of measuring step counts using a pedometer in participants with neurological conditions and healthy volunteers in relation to a manual step count tally. Oxford Centre for Enablement, Nuffield Orthopaedic Centre NHS Trust, Oxford, UK. Healthy adults (n = 13, age: mean 29, SD = 12) and adults with neurological conditions (n=20 stroke, n=16 multiple sclerosis, n=5 muscular dystrophy, n=1 spinal cord injury, n=1 traumatic brain injury; age: mean 54, SD=13). Individuals walked for 2 minutes at self-selected walking speeds (SSWS) wearing a pedometer. Healthy individuals were then asked to walk at slow walking speeds (SWS). Step counts were recorded manually and using a pedometer. In healthy individuals there was no difference between manually measured and pedometer counts during walking (P>0.05). In adults with neurological conditions the pedometers undercounted (P = 0.003); bias (random error): 27 (111); percentage variability 30% and intraclass correlation coefficient (ICC) 0.66. In neurological adults, from regression analysis the relationship between error and walking speed was cubic, with walking speed accounting for 29% of pedometer error. Healthy individuals showed greater variability and undercounting at SWS bias (random error): 10 (31), percentage variability 8% and ICC 0.73, compared with SSWS bias (random error): -3 (13), percentage variability 3% and ICC 0.84. Pedometers may undercount when used for people with neurological conditions. There may be variability in pedometer accuracy but this was not strongly related to walking speed. The suitability of pedometer use for exercise monitoring should be individually determined.

  12. Neurological examination in small animals

    Directory of Open Access Journals (Sweden)

    Viktor Paluš


    Full Text Available This clinical review about the neurological examination in small animals describes the basics about the first steps of investigation when dealing with neurological patients. The knowledge of how to perform the neurological examination is important however more important is how to correctly interpret these performed tests. A step-by-step approach is mandatory and examiners should master the order and the style of performing these tests. Neurological conditions can be sometimes very distressing for owners and for pets that might not be the most cooperating. The role of a veterinary surgeon, as a professional, is therefore to collect the most relevant history, to examine a patient in a professional manner and to give to owners an educated opinion about the further treatment and prognosis. However neurological examinations might look challenging for many. But it is only the clinical application of neuroanatomy and neurophysiology to an every-day situation for practicing veterinarians and it does not require any specific in-to-depth knowledge. This clinical review is aimed not only to provide the information on how to perform the neurological examination but it is also aimed to appeal on veterinarians to challenge their daily routine and to start practicing on neurologically normal patients. This is the best and only way to differentiate between the normal and abnormal in a real situation.

  13. Neurologic complications of bariatric surgery. (United States)

    Kumar, Neeraj


    The increasing utilization of bariatric surgery has been accompanied by an increased incidence and awareness of related neurologic complications. The purpose of this review is to provide up-to-date information on the neurologic complications related to bariatric surgery. Neurologic complications related to bariatric surgery are predominantly due to nutrient deficiencies. Common early complications include Wernicke encephalopathy due to thiamine deficiency, and late complications include myelopathy or myeloneuropathy due to vitamin B12 or copper deficiency. Early recognition and prompt institution of treatment is essential to prevent long-term disability. Often, life-long supplementation may be required.

    Full Text Available Dengue counts among the most commonly encountered arboviral diseases, representing the fastest spreading tropical illness in the world. It is prevalent in 128 countries, and each year >2.5 billion people are at risk of dengue virus infection worldwide. Neurological signs of dengue infection are increasingly reported. In this review, the main neurological complications of dengue virus infection, such as central nervous system (CNS, peripheral nervous system, and ophthalmic complications were discussed according to clinical features, treatment and possible pathogenesis. In addition, neurological complications in children were assessed due to their atypical clinical features. Finally, dengue infection and Japanese encephalitis were compared for pathogenesis and main clinical manifestations.

  15. Why neurology? Factors which influence career choice in neurology. (United States)

    Albert, Dara V; Hoyle, Chad; Yin, Han; McCoyd, Matthew; Lukas, Rimas V


    To evaluate the factors which influence the decision to pursue a career in neurology. An anonymous survey was developed using a Likert scale to rate responses. The survey was sent to adult and child neurology faculty, residents and fellows, as well as medical students applying for neurology. Descriptive statistics were used to analyse the factors of influence. Respondents were subsequently categorized into pre-neurology trainees, neurology trainees, child neurologists and adult neurologists, and differences between the groups were analysed using Pearson's chi-square test. One hundred and thirty-three anonymous responses were received. The respondents were neurologists across all levels of training and practice. Across all respondents, the most common factor of high importance was intellectual content of specialty, challenging diagnostic problems, type of patient encountered and interest in helping people. Responses were similar across the groups; however, the earliest trainees cited interest in helping people as most important, while those in neurology training and beyond cite intellectual content of the specialty as most important. As trainees transition from their earliest levels of clinical experience into working as residents and faculty, there is a shift in the cited important factors. Lifestyle and financial factors seem to be the least motivating across all groups. Encouragement from peers, mentors, faculty and practicing physicians is considered high influences in a smaller number of neurologists. This may present an opportunity for practicing neurologists to make connections with medical students early in their education in an effort to encourage and mentor candidates.

  16. Spasmodic dysphonia: description of the disease and associated neurologic disorders

    Directory of Open Access Journals (Sweden)

    Coelho, Marina Serrato


    Full Text Available Introduction: Spasmodic dysphonia (SD is a problem that affects speech and vocalization, one of the most devastating disorders of oral communication. It is characterized by vocal quality tensaestrangulada, harshly and / or interspersed with abrupt vocal attack and a great tension in the vocal tract. The etiology of spasmodic dysphonia is unclear. Some authors point to psychogenic causes, neurological or even unknown. Objective: To assess the prevalence of muscular dystonias and other neurological symptoms in patients with ED. Method: A retrospective study of 10 cases with diagnosis of ED for symptoms and neurological disorders associated. Results: There was a significant predominance of the disease in females (9:1. The average age of onset of symptoms was 32 years, ranging between 14 and 60 years. The mean disease duration was 10 years. Among the patients, 87.5% had a diagnosis of disorders of movement made by a neurologist, including orofacial dystonias (50%, essential tremor (50% and spastic paraparesis (12%. Conclusion: The presence of movement disorders followed almost all cases of spasmodic dysphonia. More studies are needed to clarify the pathophysiological basis of disease.

  17. Osteoprotegerin protects against muscular dystrophy. (United States)

    Dufresne, Sébastien S; Dumont, Nicolas A; Bouchard, Patrice; Lavergne, Éliane; Penninger, Josef M; Frenette, Jérôme


    Receptor-activator of NF-κB, its ligand RANKL, and the soluble decoy receptor osteoprotegerin are the key regulators of osteoclast differentiation and bone remodeling. Although there is a strong association between osteoporosis and skeletal muscle atrophy/dysfunction, the functional relevance of a particular biological pathway that synchronously regulates bone and skeletal muscle physiopathology still is elusive. Here, we show that muscle cells can produce and secrete osteoprotegerin and pharmacologic treatment of dystrophic mdx mice with recombinant osteoprotegerin muscles. (Recombinant osteoprotegerin-Fc mitigates the loss of muscle force in a dose-dependent manner and preserves muscle integrity, particularly in fast-twitch extensor digitorum longus.) Our data identify osteoprotegerin as a novel protector of muscle integrity, and it potentially represents a new therapeutic avenue for both muscular diseases and osteoporosis.

  18. Emerging therapies and challenges in spinal muscular atrophy. (United States)

    Farrar, Michelle A; Park, Susanna B; Vucic, Steve; Carey, Kate A; Turner, Bradley J; Gillingwater, Thomas H; Swoboda, Kathryn J; Kiernan, Matthew C


    Spinal muscular atrophy (SMA) is a hereditary neurodegenerative disease with severity ranging from progressive infantile paralysis and premature death (type I) to limited motor neuron loss and normal life expectancy (type IV). Without disease-modifying therapies, the impact is profound for patients and their families. Improved understanding of the molecular basis of SMA, disease pathogenesis, natural history, and recognition of the impact of standardized care on outcomes has yielded progress toward the development of novel therapeutic strategies and are summarized. Therapeutic strategies in the pipeline are appraised, ranging from SMN1 gene replacement to modulation of SMN2 encoded transcripts, to neuroprotection, to an expanding repertoire of peripheral targets, including muscle. With the advent of preliminary trial data, it can be reasonably anticipated that the SMA treatment landscape will transform significantly. Advancement in presymptomatic diagnosis and screening programs will be critical, with pilot newborn screening studies underway to facilitate preclinical diagnosis. The development of disease-modifying therapies will necessitate monitoring programs to determine the long-term impact, careful evaluation of combined treatments, and further acceleration of improvements in supportive care. In advance of upcoming clinical trial results, we consider the challenges and controversies related to the implementation of novel therapies for all patients and set the scene as the field prepares to enter an era of novel therapies.

  19. Prevalence and Characteristics of Chinese Patients With Duchenne and Becker Muscular Dystrophy: A Territory Wide Collaborative Study in Hong Kong. (United States)

    Chan, Sophelia H S; Lo, Ivan F M; Cherk, Sharon W W; Cheng, Wai Wai; Fung, Eva L W; Yeung, Wai Lan; Ngan, Mary; Lee, Wing Cheong; Kwong, Ling; Wong, Suet Na; Ma, Che Kwan; Tai, Shuk Mui; Ng, Grace S F; Wu, Shun Ping; Wong, Virginia C N


    The aim of this collaborative study on Duchenne muscular dystrophy and Becker muscular dystrophy is to determine the prevalence and to develop data on such patients as a prelude to the development of registry in Hong Kong. Information on clinical and molecular findings, and patient care, was systematically collected in 2011 and 2012 from all Pediatric Neurology Units in Hong Kong. Ninety patients with dystrophinopathy were identified, and 83% has Duchenne muscular dystrophy. The overall prevalence of dystrophinopathy in Hong Kong in 2010 is 1.03 per 10 000 males aged 0 to 24 years. Among the Duchenne group, we observed a higher percentage (40.6%) of point mutations with a lower percentage (45.3%) of exon deletions in our patients when compared with overseas studies. Although we observed similar percentage of Duchenne group received scoliosis surgery, ventilation support, and cardiac treatment when compared with other countries, the percentage (25%) of steroid use is lower.

  20. Neurological complication in HIV patients (United States)

    Ritarwan, K.


    Human Immunodeficiency Virus (HIV) is neurotropic and immunotropic, making themassive destruction of both systems. Although their amount has been reduced, there is still neurological presentations and complications of HIV remain common in the era of combination antiretroviral therapy (cART). Neurological opportunistic infections (OI) occur in advanced HIV diseases such as primary cerebral lymphoma, cryptococcal meningitis, cerebral toxoplasmosis, and progressive multifocal encephalopathy. Neurological problem directly related to HIV appear at any stage in the progress of HIV disease, from AIDS-associated dementia to the aseptic meningitis of primary HIV infection observed in subjects with an immune deficiency. The replication of peripheral HIV viral is able to be controlled in the era of effective antiretroviral therapy. Non-HIV-related neurological disease such as stroke increased important as the HIV population ages.

  1. Neurologic disorder and criminal responsibility. (United States)

    Yaffe, Gideon


    Sufferers from neurologic and psychiatric disorders are not uncommonly defendants in criminal trials. This chapter surveys a variety of different ways in which neurologic disorder bears on criminal responsibility. It discusses the way in which a neurologic disorder might bear on the questions of whether or not the defendant acted voluntarily; whether or not he or she was in the mental state that is required for guilt for the crime; and whether or not he or she is deserving of an insanity defense. The discussion demonstrates that a just determination of whether a sufferer from a neurologic disorder is diminished in his or her criminal responsibility for harmful conduct requires equal appreciation of the nature of the relevant disorder and its impact on behavior, on the one hand, and of the legal import of facts about the psychologic mechanisms through which behavior is generated, on the other. © 2013 Elsevier B.V.

  2. Neurological Complications of Bariatric Surgery. (United States)

    Goodman, Jerry Clay


    Obesity has attained pandemic proportions, and bariatric surgery is increasingly being employed resulting in turn to more neurological complications which must be recognized and managed. Neurological complications may result from mechanical or inflammatory mechanisms but primarily result from micro-nutritional deficiencies. Vitamin B12, thiamine, and copper constitute the most frequent deficiencies. Neurological complications may occur at reasonably predictable times after bariatric surgery and are associated with the type of surgery used. During the early post-operative period, compressive or stretch peripheral nerve injury, rhabdomyolysis, Wernicke's encephalopathy, and inflammatory polyradiculoneuropathy may occur. Late complications ensue after months to years and include combined system degeneration (vitamin B12 deficiency) and hypocupric myelopathy. Bariatric surgery patients require careful nutritional follow-up with routine monitoring of micronutrients at 6 weeks and 3, 6, and 12 months post-operatively and then annually after surgery and multivitamin supplementation for life. Sustained vigilance for common and rare neurological complications is essential.

  7. Historical perspective of Indian neurology

    Directory of Open Access Journals (Sweden)

    Shrikant Mishra


    Full Text Available Objective: To chronicle the history of medicine and neurology in India with a focus on its establishment and evolution. Background: The history of neurology in India is divided into two periods: ancient and modern. The ancient period dates back to the mid-second millennium Before Christ (B.C. during the creation of the Ayurvedic Indian system of Medicine, which detailed descriptions of neurological disorders called Vata Vyadhi. The early 20 th century witnessed the birth of modern Indian medicine with the onset of formal physician training at the nation′s first allopathic medical colleges located in Madras (1835, Calcutta (1835 and Mumbai (1848. Prior to India′s independence from Britain in 1947, only 25 medical schools existed in the entire country. Today, there are over 355. In 1951, physicians across the field of neurology and neurosurgery united to create the Neurological Society of India (NSI. Four decades later in 1991, neurologists branched out to establish a separate organization called the Indian Academy of Neurology (IAN. Design/Methods: Information was gathered through literature review using PubMed, MD Consult, OVID, primary texts and research at various academic institutions in India. Results: Neurological disorders were first described in ancient India under Ayurveda. The transition to modern medicine occurred more recently through formal training at medical schools beginning in the 1930′s. Early pioneers and founders of the NSI (1951 include Dr. Jacob Chandy, Dr. B Ramamurthi, Dr. S. T. Narasimhan and Dr. Baldev Singh. Later, Dr. J. S. Chopra, a prominent neurologist and visionary, recognized the need for primary centers of collaboration and subsequently established the IAN (1991. The future of Neurology in India is growing rapidly. Currently, there are 1100 practicing neurologists and more than 150 post-graduate trainees who join the ranks every year. As the number of neurologists rises across India, there is an increase in

  8. Adult Hip Flexion Contracture due to Neurological Disease: A New Treatment Protocol—Surgical Treatment of Neurological Hip Flexion Contracture

    Directory of Open Access Journals (Sweden)

    Alberto Nicodemo


    Full Text Available Congenital, traumatic, or extrinsic causes can lead people to paraplegia; some of these are potentially; reversible and others are not. Paraplegia can couse hip flexion contracture and, consequently, pressure sores, scoliosis, and hyperlordosis; lumbar and groin pain are strictly correlated. Scientific literature contains many studies about children hip flexion related to neurological diseases, mainly caused by cerebral palsy; only few papers focus on this complication in adults. In this study we report our experience on surgical treatment of adult hip flexion contracture due to neurological diseases; we have tried to outline an algorithm to choose the best treatment avoiding useless or too aggressive therapies. We present 5 cases of adult hips flexion due to neurological conditions treated following our algorithm. At 1-year-follow-up all patients had a good clinical outcome in terms of hip range of motion, pain and recovery of walking if possible. In conclusion we think that this algorithm could be a good guideline to treat these complex cases even if we need to treat more patients to confirm this theory. We believe also that postoperation physiotherapy it is useful in hip motility preservation, improvement of muscular function, and walking ability recovery when possible.

  9. Therapeutics development for spinal muscular atrophy


    Sumner, Charlotte J.


    Spinal muscular atrophy is an autosomal recessive motor neuron disease that is the leading inherited cause of infant and early childhood mortality. Spinal muscular atrophy is caused by mutation of the telomeric copy of the survival motor neuron gene (SMN1), but all patients retain a centromeric copy of the gene,SMN2. SMN2 produces reduced amounts of full-length SMN mRNA, and spinal muscular atrophy likely results from insufficient levels of SMN protein in motor neurons. The SMN protein plays ...

  10. Duchenne muscular dystrophy: current cell therapies. (United States)

    Sienkiewicz, Dorota; Kulak, Wojciech; Okurowska-Zawada, Bożena; Paszko-Patej, Grażyna; Kawnik, Katarzyna


    Duchenne muscular dystrophy is a genetically determined X-linked disease and the most common, progressive pediatric muscle disorder. For decades, research has been conducted to find an effective therapy. This review presents current therapeutic methods for Duchenne muscular dystrophy, based on scientific articles in English published mainly in the period 2000 to 2014. We used the PubMed database to identify and review the most important studies. An analysis of contemporary studies of stem cell therapy and the use of granulocyte colony-stimulating factor (G-CSF) in muscular dystrophy was performed.

  11. Hippocrates: the forefather of neurology. (United States)

    Breitenfeld, T; Jurasic, M J; Breitenfeld, D


    Hippocrates is one of the most influential medical doctors of all times. He started observing and experimenting in times of mysticism and magic. He carried a holistic and humanitarian approach to the patient with examination as the principal approach-inspection, palpation and auscultation are still the most important tools in diagnosing algorithms of today. He had immense experience with the human body most likely due to numerous wound treatments he had performed; some even believe he performed autopsies despite the negative trend at the time. Hippocrates identified the brain as the analyst of the outside world, the interpreter of consciousness and the center of intelligence and willpower. Interestingly, Hippocrates was aware of many valid concepts in neurology; his treatise On the Sacred Disease was the most important for understanding neurology and epilepsy. His other ideas pioneered modern day neurology mentioning neurological diseases like apoplexy, spondylitis, hemiplegia, and paraplegia. Today, 10 % of neurological Pubmed and 7 % of neuroscience Scopus reviews mention Corpus Hippocraticum as one of the sources. Therefore, Hippocrates may be considered as the forefather of neurology.

  12. Thomas Willis, the Restoration and the First Works of Neurology. (United States)

    Caron, Louis


    This article provides a new consideration of how Thomas Willis (1621-75) came to write the first works of 'neurology', which was in its time a novel use of cerebral and neural anatomy to defend philosophical claims about the mind. Willis's neurology was shaped by the immediate political and religious contexts of the English Civil War and Restoration. Accordingly, the majority of this paper is devoted to uncovering the political necessities Willis faced during the Restoration of the English monarchy in 1660, with particular focus on the significance of Willis's dedication of his neurology and natural philosophy to the Archbishop of Canterbury, Gilbert Sheldon. Because the Restoration of Charles II brought only a semblance of order and peace, Willis and his allies understood the need for a coherent defense of the authority of the English church and its liturgy. Of particular importance to Sheldon and Willis (and to others in Sheldon's circle) were the specific ceremonies described in the Book of Common Prayer, a manual that directed the congregation to assume various postures during public worship. This article demonstrates that Willis's neurology should be read as an intervention in these debates, that his neurology would have been read at the time as an attempt to ground orthodox worship in the structure of the brain and nerves. The political necessities that helped to shape Willis's project also help us to better understand Willis's innovative insistence that philosophical statements about the mind should be formulated only after a comprehensive anatomical investigation of the brain and nerves.

  13. Carrier detection of duchenne and becker muscular dystrophy using muscle dystrophin immunohistochemistry

    Directory of Open Access Journals (Sweden)

    Acary S. Bulle Oliveira


    Full Text Available To ascertain whether dystrophin immunohistochemistry could improve DMD/ BMD carrier detection, we analyzed 14 muscle biopsies from 13 DMD and one BMD probable and possible carriers. All women were also evaluated using conventional methods, including genetic analysis, clinical and neurological evaluation, serum CK levels, KMG, and muscle biopsy. In 6 cases, there was a mosaic of dystrophin-positive and dystrophin-deficient fibers that allowed to make the diagnosis of a carrier state. Comparing dystrophin immunohistochemistry to the traditional methods, it was noted that this method is less sensitive than serum CK measuremens, but is more sensitive than EMG and muscle biopsy. The use of dystrophin immunohistochemistry in addition to CK, EMG and muscle biopsy improved the accuracy of carrier detection. This method is also helpful to distinguish manifesting DMD carriers from patients with other neuromuscular diseases like limb-girdle muscular dystrophy and spinal muscular atrophy.

  14. Peripheral nerve pathology at fixed stage in spinal muscular atrophy with respiratory distress type 1. (United States)

    Ikeda, Azusa; Yamashita, Sumimasa; Tsuyusaki, Yu; Tanaka, Mio; Tanaka, Yukichi; Hashiguchi, Akihiro; Takashima, Hiroshi; Goto, Tomohide


    Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is characterized by severe respiratory failure due to diaphragmatic paralysis and distal muscular weakness in early infancy. After an initial decline in respiratory state and motor function until 1-2years of age, residual capabilities reach a plateau. We report the peripheral neuropathological findings of a patient with SMARD1 at 1year and 1month of age, when his muscle strength and respiratory symptoms had deteriorated and then stabilized for several months. Peripheral nerve biopsy revealed severely progressed axonal degeneration. This finding suggests the rapid progression of peripheral axonal neuropathy in SMARD1 that leads to its characteristic clinical course of respiratory failure and paralysis in the early infantile period.

  15. Neurogenic muscular atrophy and low density of large myelinated fibres of sural nerve in chorea-acanthocytosis


    Ohnishi, A; Sato, Y; Nagara, H; Sakai, T; Iwashita, H; Kuroiwa, Y; Nakamura, T; Shida, K


    In three cases of chorea-acanthocytosis (acanthocytosis and neurological disease, or familial degeneration of the basal ganglia with acanthocytosis), biopsies of short peroneal muscles and sural nerves were studied histologically. The muscles showed groups of atrophic fibres with clumping of sarcolemmal nuclei in all cases. It was concluded that neurogenic muscular atrophy should be included as one of the main pathological findings in chorea-acanthocytosis. The sural nerves showed a small num...

  17. Muscular dystrophy: from pathogenesis to strategy. (United States)

    Hsu, Yaw-Don


    Muscular dystrophies are a genetically heterogeneous group of degenerative muscle disorders. It characterized by progressive muscle wasting and weakness of variable distribution and severity. There are several subgroups including Duchenne/Becker, fascioscapulohumeral, limb-girdle, oculopharngeal, and congenital muscular dystrophy. Diagnosis is dependent to the characteristic clinical features in distribution of predominant muscle weakness, disease course and age onset as well as variable serum concentration creatine kinase, muscle histology, and genetic inheritance. Nearly 30 genes and encoded proteins are known to give rise to various forms of muscular dystrophy. Development of new prospects therapy for the muscular dystrophies is a big challenge. The target of strategies is aimed at inducing of a functional protein and improving the function of muscle weakness. These strategies include gene, cell and pharmacological therapies. However, efficiency of systemic delivery vectors to targets, immune reaction to vector and gene products, and toxicity to vector that must be solved before an effective treatment is available.

  18. Duchenne muscular dystrophy: Case report and review. (United States)

    Sinha, Rupam; Sarkar, Soumyabrata; Khaitan, Tanya; Dutta, Soumyajit


    Muscular dystrophies are a clinically and heterogeneous group of disorders that all share clinical characteristics of progressive muscular weakness. Duchenne muscular dystrophy (DMD) is the most common X-linked disorder muscular dystrophy in children, presenting in early childhood and characterized by proximal muscle weakness and calf hypertrophy in affected boys. There is usually delay in motor development and eventually wheelchair confinement followed by premature death from cardiac or respiratory complications. Treatment modalities such as corticosteroid therapy and use of intermittent positive pressure ventilation have provided improvements in function, ambulation, quality of life, and life expectancy, although novel therapies still aim to provide a cure for this devastating disorder. Here, we present a case of DMD in a 12-year-old male with remarkable clinical and oral manifestations.

  1. Reality television and the muscular male ideal. (United States)

    Dallesasse, Starla L; Kluck, Annette S


    Although researchers have examined the negative effects of viewing reality television (RTV) on women's body image, this research has not been extended to men. Exploring the extent to which RTV depicts men who embody the muscular ideal may enhance our understanding of the potential influence of this media genre. We explored the extent to which RTV depicted men who embodied the muscular ideal using a quantitative content analysis. Based on binomial tests, the primary male cast members of programs airing on networks popular among young adult men during the Fall 2009 broadcast season were more muscular, with lower levels of body fat, than average U.S. men. The chest-to-waist and shoulder-to-waist ratios of these cast members did not differ as a function of program type (i.e., reality drama, endurance, and romance). Young men who view RTV programs included in the present study would be exposed to an unrepresentative muscular ideal. Published by Elsevier Ltd.

  8. A hyperacute neurology team - transforming emergency neurological care. (United States)

    Nitkunan, Arani; MacDonald, Bridget K; Boodhoo, Ajay; Tomkins, Andrew; Smyth, Caitlin; Southam, Medina; Schon, Fred


    We present the results of an 18-month study of a new model of how to care for emergency neurological admissions. We have established a hyperacute neurology team at a single district general hospital. Key features are a senior acute neurology nurse coordinator, an exclusively consultant-delivered service, acute epilepsy nurses, an acute neurophysiology service supported by neuroradiology and acute physicians and based within the acute medical admissions unit. Key improvements are a major increase in the number of patients seen, the speed with which they are seen and the percentage seen on acute medical unit before going to the general wards. We have shown a reduced length of stay and readmission rates for patients with epilepsy. Epilepsy accounted for 30% of all referrals. The cost implications of running this service are modest. We feel that this model is worthy of widespread consideration. © Royal College of Physicians 2017. All rights reserved.

  10. [Deficiency, disability, neurology and literature]. (United States)

    Collado-Vázquez, Susana; Cano-de-la-Cuerda, Roberto; Jiménez-Antona, Carmen; Muñoz-Hellín, Elena


    Literature has always been attracted to neurological pathologies and the numerous works published on the subject are proof of this. Likewise, a number of physicians have been fiction writers and have drawn on their scientific knowledge to help develop their stories. The study addresses the appearance of neurological pathologies in a sample of literary works and examines the description of the disease, its treatment, the patient's view and the relationship between healthcare professionals and the socio-familial milieu. We review some of the greatest literary works of all times that deal with neurological pathologies, such as Don Quixote, Julius Caesar, David Copperfield, The Idiot or Miau, and many of them are seen to offer a very faithful portrayal of the disease. Similarly, we have also reviewed works that provide a personal account of life with neurological diseases and the ensuing disability written either by the patients themselves or by their relatives, examples being The Diving Bell and the Butterfly, My Left Foot or One Chance in a Thousand. Literature has helped to offer a realistic vision of neurologically-based pathologies and the healthcare professionals who work with them; there are many examples that portray the experiences of the patients themselves and the importance of support from the family is a feature that is constantly underlined.

  11. Neurological complications of cardiac surgery. (United States)

    Gottesman, Rebecca F; McKhann, Guy M; Hogue, Charles W


    Neurological injury resulting from cardiac surgery has a range of manifestations from focal neurological deficit to encephalopathy or coma. As the safety of drug-eluting stents comes into question, more patients will likely undergo coronary artery bypass graft surgery. These projections, along with the growing proportions of elderly patients and those with comorbidities, portend the potential for rising rates of perioperative neurological complications. The risk for neurological injury may be determined by the type of procedure, by patient-specific characteristics, and by the extent of cerebral embolization and hypoperfusion during and after surgery. Changes in surgical techniques, including the use of off-pump surgery, have not decreased rates of brain injury from cardiac surgery. When appropriate, modern neuroimaging techniques should be used in postoperative patients to confirm diagnosis, to provide information on potential etiology, to direct appropriate therapy, and to help in prognostication. Management of postoperative medications and early use of rehabilitation services is a recommended strategy to optimize the recovery for individuals with neurological injury after cardiac surgery.

  12. Spinal and bulbar muscular atrophy. (United States)

    Lieberman, Andrew P


    Spinal and bulbar muscular atrophy (SBMA) is an adult-onset degenerative disorder of the neuromuscular system resulting in slowly progressive weakness and atrophy of the proximal limb and bulbar muscles. The disease is caused by the expansion of a CAG/glutamine tract in the amino-terminus of the androgen receptor. That SBMA exclusively affects males reflects the fact that critical pathogenic events are hormone-dependent. These include translocation of the polyglutamine androgen receptor from the cytoplasm to the nucleus and unfolding of the mutant protein. Studies of the pathology of SBMA subjects have revealed nuclear aggregates of the mutant androgen receptor, loss of lower motor neurons in the brainstem and spinal cord, and both neurogenic and myopathic changes in skeletal muscle. Mechanisms underlying disease pathogenesis include toxicity in both lower motor neurons and skeletal muscle, where effects on transcription, intracellular transport, and mitochondrial function have been documented. Therapies to treat SBMA patients remain largely supportive, although experimental approaches targeting androgen action or promoting degradation of the mutant androgen receptor protein or the encoding RNA are under active study.

    Propionic acidemia (PA) is an organic acidemia which has a broad range of neurological complications, including developmental delay, intellectual disability, structural abnormalities, metabolic stroke-like episodes, seizures, optic neuropathy, and cranial nerve abnormalities. As the PA consensus conference hosted by Children's National Medical Center progressed from January 28 to 30, 2011, it became evident that neurological complications were common and a major component of morbidity, but the role of imaging and the basis for brain pathophysiology were unclear. This paper reviews the hypothesized pathophysiology, presentation and uses the best available evidence to suggest programs for treatment, imaging, and monitoring the neurological complications of PA.

  14. Quality Metrics in Inpatient Neurology. (United States)

    Dhand, Amar


    Quality of care in the context of inpatient neurology is the standard of performance by neurologists and the hospital system as measured against ideal models of care. There are growing regulatory pressures to define health care value through concrete quantifiable metrics linked to reimbursement. Theoretical models of quality acknowledge its multimodal character with quantitative and qualitative dimensions. For example, the Donabedian model distils quality as a phenomenon of three interconnected domains, structure-process-outcome, with each domain mutually influential. The actual measurement of quality may be implicit, as in peer review in morbidity and mortality rounds, or explicit, in which criteria are prespecified and systemized before assessment. As a practical contribution, in this article a set of candidate quality indicators for inpatient neurology based on an updated review of treatment guidelines is proposed.

    Lee, Hyangsook; Park, Hi-Joon; Park, Jongbae; Kim, Mi-Ja; Hong, Meesuk; Yang, Jongsoo; Choi, Sunmi; Lee, Hyejung


    Acupuncture has been widely used for a range of neurological disorders. Despite its popularity, the evidence to support the use of acupuncture is contradictory. This review was designed to summarize and to evaluate the available evidence of acupuncture for neurological disorders. Most of the reviewed studies suffer from lack of methodological rigor. Owing to paucity and poor quality of the primary studies, no firm conclusion could be drawn on the use of acupuncture for epilepsy, Alzheimer's disease, Parkinson's disease, ataxic disorders, multiple sclerosis, amyotrophic lateral sclerosis and spinal cord injury. For stroke rehabilitation, the evidence from recent high-quality trials and previous systematic reviews is not convincing. More rigorous trials are warranted to establish acupuncture's role in neurological disorders.

    Beck, Malene; Martinsen, Bente; Poulsen, Ingrid


    AIMS AND OBJECTIVES: To examine the environment surrounding hospital meals for patients with neurological diseases. BACKGROUND: A determined effort has been made to optimise the nutrition of hospitalised patients. However, the organisation of mealtimes and their relational and aesthetic aspects...... challenged by the design of the physical space and institutional structures. CONCLUSION: This study contributes to our understanding of the environment surrounding hospital meals for patients with neurological diseases. Based on this study, it can be concluded that meals were at a high risk of being served...... as a mindless task without the recognition that mealtimes are sensed with the whole body of the patient and not only by the mouth. RELEVANCE TO CLINICAL PRACTICE: The importance of the mealtime environment must be acknowledged because it serves as a communicative aspect for neurological patients by letting them...

  1. [Neurological complication of influenza infections]. (United States)

    Brydak, Lidia B


    The aim of this study was to present neurological complications of influenza infections. Infections caused by influenza viruses can be very serious and may lead even to death resulted from the post-infectious complications. The most often occurring complications are pneumonia, bronchitis, bronchiolitis, myocarditis and otitis media. The other group is neurological post-influenza complications, including dementia, epileptic disorders, cerebrovascular disease, febrile convulsions, toxic encephalopathy, encephalitis, meningitis, subarachnoid hemorrhages, lethargic encephalitis, psychosis or increase in the number of cases of Parkinson's disease. The first way of prevention of influenza is vaccination that results in healthy, social and economic benefits.

  2. Neurological complications following measles vaccination. (United States)

    Allerdist, H


    In Hamburg 18 cases of neurological complications following vaccination with live measles virus vaccine (including 2 cases of abortive encephalopathy) have been observed between 1971--1978. A causal connection was assumed in 14 cases, that means an incidence of 1 neurological complication per 2,500 vaccinees and an incidence of 1 abortive encephalopathy per 17,650 vaccinees. These results differ from studies of various countries which used the same vaccine strain (Schwarz). Clinical symptoms, age distribution and incubation period are demonstrated. The prognosis seems to be good; the risk of vaccination compared to the risk following original measles is between 1:10 (convulsions) and 1:18 (encephalopathy).

  3. Nanotherapy for Duchenne muscular dystrophy. (United States)

    Nance, Michael E; Hakim, Chady H; Yang, N Nora; Duan, Dongsheng


    Duchenne muscular dystrophy (DMD) is a lethal X-linked childhood muscle wasting disease caused by mutations in the dystrophin gene. Nanobiotechnology-based therapies (such as synthetic nanoparticles and naturally existing viral and nonviral nanoparticles) hold great promise to replace and repair the mutated dystrophin gene and significantly change the disease course. While a majority of DMD nanotherapies are still in early preclinical development, several [such as adeno-associated virus (AAV)-mediated systemic micro-dystrophin gene therapy] are advancing for phase I clinical trials. Recent regulatory approval of Ataluren (a nonsense mutation read-through chemical) in Europe and Exondys51 (an exon-skipping antisense oligonucleotide drug) in the United States shall offer critical insight in how to move DMD nanotherapy to human patients. Progress in novel, optimized nano-delivery systems may further improve emerging molecular therapeutic modalities for DMD. Despite these progresses, DMD nanotherapy faces a number of unique challenges. Specifically, the dystrophin gene is one of the largest genes in the genome while nanoparticles have an inherent size limitation per definition. Furthermore, muscle is the largest tissue in the body and accounts for 40% of the body mass. How to achieve efficient bodywide muscle targeting in human patients with nanomedication remains a significant translational hurdle. New creative approaches in the design of the miniature micro-dystrophin gene, engineering of muscle-specific synthetic AAV capsids, and novel nanoparticle-mediated exon-skipping are likely to result in major breakthroughs in DMD therapy.

  4. [Neurology in medieval regimina sanitatis]. (United States)

    de Frutos González, V; Guerrero Peral, A L


    In medical medieval literature some works about dietetics stand out. Dietetics, as a separate branch of medicine, includes not only food or drinks, but other environmental factors influencing on health. They are known as regimina sanitatis or salutis, and specially developed in the Christian west. They generally consisted of a balance between the Galenic "six non-natural things"; factors regulating health and its protection: environment, exercise, food, sleep, bowel movements and emotions. After reviewing the sources and defining the different stages of this genre, we have considered three of the most out-standing medieval regimina, the anonymous Regimen sanitatis salernitanum, Arnaldo de Vilanova's Regimen sanitatis ad regem aragonum and Bernardo de Gordon's Tractatus of conservatione vite humane. In them we review references to neurological disease. Though not independently considered, there is a significant presence of neurological diseases in the regimina. Dietetics measures are proposed to preserve memory, nerves, or hearing, as well as for the treatment of migraine, epilepsy, stroke or dizziness. Regimina are quiet representative among medical medieval literature, and they show medieval physicians vision of neurological diseases. Dietetics was considered useful to preserve health, and therapeutics was based on natural remedies. 2010 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

  5. [Neurology of hysteria (conversion disorder)]. (United States)

    Sonoo, Masahiro


    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.

  8. Education Research: Neurology training reassessed (United States)

    Maas, Matthew B.; Coleman, Mary; Jozefowicz, Ralph; Engstrom, John


    Objective: To assess the strengths and weaknesses of neurology resident education using survey methodology. Methods: A 27-question survey was sent to all neurology residents completing residency training in the United States in 2011. Results: Of eligible respondents, 49.8% of residents returned the survey. Most residents believed previously instituted duty hour restrictions had a positive impact on resident quality of life without impacting patient care. Most residents rated their faculty and clinical didactics favorably. However, many residents reported suboptimal preparation in basic neuroscience and practice management issues. Most residents (71%) noted that the Residency In-service Training Examination (RITE) assisted in self-study. A minority of residents (14%) reported that the RITE scores were used for reasons other than self-study. The vast majority (86%) of residents will enter fellowship training following residency and were satisfied with the fellowship offers they received. Conclusions: Graduating residents had largely favorable neurology training experiences. Several common deficiencies include education in basic neuroscience and clinical practice management. Importantly, prior changes to duty hours did not negatively affect the resident perception of neurology residency training. PMID:23091077

  9. International electives in neurology training (United States)

    Lyons, Jennifer L.; Coleman, Mary E.; Engstrom, John W.


    Objective: To ascertain the current status of global health training and humanitarian relief opportunities in US and Canadian postgraduate neurology programs. Background: There is a growing interest among North American trainees to pursue medical electives in low- and middle-income countries. Such training opportunities provide many educational and humanitarian benefits but also pose several challenges related to organization, human resources, funding, and trainee and patient safety. The current support and engagement of neurology postgraduate training programs for trainees to pursue international rotations is unknown. Methods: A survey was distributed to all program directors in the United States and Canada (December 2012–February 2013) through the American Academy of Neurology to assess the training opportunities, institutional partnerships, and support available for international neurology electives. Results: Approximately half of responding programs (53%) allow residents to pursue global health–related electives, and 11% reported that at least 1 trainee participated in humanitarian relief during training (survey response rate 61%, 143/234 program directors). Canadian programs were more likely to allow residents to pursue international electives than US programs (10/11, 91% vs 65/129, 50%, p = 0.023). The number of trainees participating in international electives was low: 0%–9% of residents (55% of programs) and 10%–19% of residents (21% of programs). Lack of funding was the most commonly cited reason for residents not participating in global health electives. If funding was available, 93% of program directors stated there would be time for residents to participate. Most program directors (75%) were interested in further information on global health electives. Conclusions: In spite of high perceived interest, only half of US neurology training programs include international electives, mostly due to a reported lack of funding. By contrast, the majority

  10. Is restlessness best understood as a process? Reflecting on four boys’ restlessness during music therapy in kindergarten (United States)

    Helle-Valle, Anna; Binder, Per-Einar; Anderssen, Norman; Stige, Brynjulf


    ABSTRACT ADHD can be considered an internationally recognized framework for understanding children’s restlessness. In this context, children’s restlessness is understood as a symptom of neurodevelopmental disorder. However, there are other possible understandings of children’s restlessness. In this article, we explore four boys’ collaborative and creative process as it is described and understood by three adults. The process is framed by a community music therapy project in a Norwegian kindergarten, and we describe four interrelated phases of this process: Exploring musical vitality and cooperation, Consolidating positions, Performing together, and Discovering ripple effects. We discuss these results in relation to seven qualities central to a community music therapy approach: participation, resource orientation, ecology, performance, activism, reflexivity and ethics. We argue that in contrast to a diagnostic approach that entails a focus on individual problems, a community music therapy approach can shed light on adult and systemic contributions to children’s restlessness.

  11. Metabolic syndrome as a risk factor for neurological disorders. (United States)

    Farooqui, Akhlaq A; Farooqui, Tahira; Panza, Francesco; Frisardi, Vincenza


    The metabolic syndrome is a cluster of common pathologies: abdominal obesity linked to an excess of visceral fat, insulin resistance, dyslipidemia and hypertension. At the molecular level, metabolic syndrome is accompanied not only by dysregulation in the expression of adipokines (cytokines and chemokines), but also by alterations in levels of leptin, a peptide hormone released by white adipose tissue. These changes modulate immune response and inflammation that lead to alterations in the hypothalamic 'bodyweight/appetite/satiety set point,' resulting in the initiation and development of metabolic syndrome. Metabolic syndrome is a risk factor for neurological disorders such as stroke, depression and Alzheimer's disease. The molecular mechanism underlying the mirror relationship between metabolic syndrome and neurological disorders is not fully understood. However, it is becoming increasingly evident that all cellular and biochemical alterations observed in metabolic syndrome like impairment of endothelial cell function, abnormality in essential fatty acid metabolism and alterations in lipid mediators along with abnormal insulin/leptin signaling may represent a pathological bridge between metabolic syndrome and neurological disorders such as stroke, Alzheimer's disease and depression. The purpose of this review is not only to describe the involvement of brain in the pathogenesis of metabolic syndrome, but also to link the pathogenesis of metabolic syndrome with neurochemical changes in stroke, Alzheimer's disease and depression to a wider audience of neuroscientists with the hope that this discussion will initiate more studies on the relationship between metabolic syndrome and neurological disorders. © Springer Basel AG 2011

    D. A. Kharlamov


    Full Text Available The literature review gives data on the role of mitochondrial disorders in the pathogenesis of different progressive muscular dystrophies. It describes changes in Duchenne, limb-girdle, facial scapulohumeral (Landuzi—Degerina muscular dystrophies. The review is based on both clinical and experimental animal studies. Along with the implication of mitochondria in the pathogenesis of the diseases, it describes muscular dystrophy treatment options compensating for energy disorders and overcoming oxidative stress and mitochondrial dysfunction. Mitochondrial studies in different muscle diseases hand physicians treatment modalities that fail to lead to recovery, but compensate for disorders caused by mutations in the genetic apparatus. 

  14. Circulating Biomarkers for Duchenne Muscular Dystrophy. (United States)

    Aartsma-Rus, Annemieke; Spitali, Pietro


    Duchenne muscular dystrophy is the most common form of muscular dystrophy. Genetic and biochemical research over the years has characterized the cause, pathophysiology and development of the disease providing several potential therapeutic targets and/or biomarkers. High throughput - omic technologies have provided a comprehensive understanding of the changes occurring in dystrophic muscles. Murine and canine animal models have been a valuable source to profile muscles and body fluids, thus providing candidate biomarkers that can be evaluated in patients. This review will illustrate known circulating biomarkers that could track disease progression and response to therapy in patients affected by Duchenne muscular dystrophy. We present an overview of the transcriptomic, proteomic, metabolomics and lipidomic biomarkers described in literature. We show how studies in muscle tissue have led to the identification of serum and urine biomarkers and we highlight the importance of evaluating biomarkers as possible surrogate endpoints to facilitate regulatory processes for new medicinal products.

  15. [Human myopathy and animal muscular dystrophy]. (United States)

    Schapira, G; Dreyfus, J C; Schapira, F


    Two hereditary muscular dystrophies similar to human progressive muscular dystrophy (P.M.D. Duchenne type) have been isolated in animals, one in mouse, the other in chicken. The decrease in the activity of glycogenolytic enzymes is similar to that observed in denervated muscle. Isozymic fetal types for several muscular enzymes have been observed as well in chicken as in man, but this fetal type may also be found in neurogenic atrophy. The release in circulation of muscle enzymes seems more specific. But the origin of the genetic lesion is still unknown. We describe here the three different theories about this problem: i.e. neurogenic, vascular, or myogenic. This last theory implies a trouble of membrane permeability.

  16. Muscular pathology: echographic and NMR imaging aspects

    International Nuclear Information System (INIS)

    Pascal-Suisse, P.; Beaurain, P.; Mougniot, C.


    A comparison of echographic techniques and NMR imaging has been done for the diagnosis of muscular trauma and tumor pathologies. In traumatic pathology, the echographic analysis allows to determine the complete assessment of recent muscular injuries. NMR imaging can be used in granuloma or fibrous callosity appreciation and for the analysis of deep injury (muscles and muscles-tendon junctions) and of muscular aponeurosis. Echography must be used together with color coding Doppler technique in the diagnosis of tumor pathology and for the study of slow fluxes. The recently available energy Doppler technique seems to be powerful in the study of vascularization of small expansive formations, but their extension to adjacent bone or tissue can only be appreciated using NMR imaging.

  17. Model Organisms in the Fight against Muscular Dystrophy: Lessons from Drosophila and Zebrafish

    Directory of Open Access Journals (Sweden)

    Emilie Plantié


    Full Text Available Muscular dystrophies (MD are a heterogeneous group of genetic disorders that cause muscle weakness, abnormal contractions and muscle wasting, often leading to premature death. More than 30 types of MD have been described so far; those most thoroughly studied are Duchenne muscular dystrophy (DMD, myotonic dystrophy type 1 (DM1 and congenital MDs. Structurally, physiologically and biochemically, MDs affect different types of muscles and cause individual symptoms such that genetic and molecular pathways underlying their pathogenesis thus remain poorly understood. To improve our knowledge of how MD-caused muscle defects arise and to find efficacious therapeutic treatments, different animal models have been generated and applied. Among these, simple non-mammalian Drosophila and zebrafish models have proved most useful. This review discusses how zebrafish and Drosophila MD have helped to identify genetic determinants of MDs and design innovative therapeutic strategies with a special focus on DMD, DM1 and congenital MDs.

  18. The adaptations to strength training : morphological and neurological contributions to increased strength. (United States)

    Folland, Jonathan P; Williams, Alun G


    High-resistance strength training (HRST) is one of the most widely practiced forms of physical activity, which is used to enhance athletic performance, augment musculo-skeletal health and alter body aesthetics. Chronic exposure to this type of activity produces marked increases in muscular strength, which are attributed to a range of neurological and morphological adaptations. This review assesses the evidence for these adaptations, their interplay and contribution to enhanced strength and the methodologies employed. The primary morphological adaptations involve an increase in the cross-sectional area of the whole muscle and individual muscle fibres, which is due to an increase in myofibrillar size and number. Satellite cells are activated in the very early stages of training; their proliferation and later fusion with existing fibres appears to be intimately involved in the hypertrophy response. Other possible morphological adaptations include hyperplasia, changes in fibre type, muscle architecture, myofilament density and the structure of connective tissue and tendons. Indirect evidence for neurological adaptations, which encompasses learning and coordination, comes from the specificity of the training adaptation, transfer of unilateral training to the contralateral limb and imagined contractions. The apparent rise in whole-muscle specific tension has been primarily used as evidence for neurological adaptations; however, morphological factors (e.g. preferential hypertrophy of type 2 fibres, increased angle of fibre pennation, increase in radiological density) are also likely to contribute to this phenomenon. Changes in inter-muscular coordination appear critical. Adaptations in agonist muscle activation, as assessed by electromyography, tetanic stimulation and the twitch interpolation technique, suggest small, but significant increases. Enhanced firing frequency and spinal reflexes most likely explain this improvement, although there is contrary evidence

  19. [Glucocorticoids in neurology: mechanism of action, applications and side effects]. (United States)

    Finsterer, J; Frank, M


    Glucocorticoids represent a cornerstone in the therapy for many neurological disorders. Even though their mechanism of action is still not completely understood, synthetic glucocorticoids are given as first line drugs in a number of immunological and non-immunological disorders of the central or peripheral nervous system. For most of these disorders, however, the level of evidence that glucocorticoids are truly effective is still not sufficient. This is why treatment with glucocorticoids cannot be recommended on an evidenced-based level for many of these disorders. Due to the huge number of acute or chronic side effects, it is essential that the effects are documented by more randomised placebo-controlled cross-over trials. Generally, glucocorticoids can no longer be omitted in the treatment of neurological disorders, the indication to apply glucocorticoids, however, needs to be thoroughly balanced in the light of their many side effects. © Georg Thieme Verlag KG Stuttgart · New York.

  20. Neurologic manifestations of hypothyroidism in dogs. (United States)

    Bertalan, Abigail; Kent, Marc; Glass, Eric


    Hypothyroidism is a common endocrine disease in dogs. A variety of clinicopathologic abnormalities may be present; however, neurologic deficits are rare. In some instances, neurologic deficits may be the sole manifestation of hypothyroidism. Consequent ly, the diagnosis and management of the neurologic disorders associated with hypothyroidism can be challenging. This article describes several neurologic manifestations of primary hypothyroidism in dogs; discusses the pathophysiology of hypothyroidism-induced neurologic disorders affecting the peripheral and central nervous systems; and reviews the evidence for the neurologic effects of hypothyroidism.

  3. Growth and psychomotor development of patients with Duchenne muscular dystrophy. (United States)

    Sarrazin, Elisabeth; von der Hagen, Maja; Schara, Ulrike; von Au, Katja; Kaindl, Angela M


    Duchenne muscular dystrophy (DMD) is one of the most common hereditary degenerative neuromuscular diseases and caused by mutations in the dystrophin gene. The objective of the retrospective study was to describe growth and psychomotor development of patients with DMD and to detect a possible genotype-phenotype correlation. Data from 263 patients with DMD (mean age 7.1 years) treated at the Departments of Pediatric Neurology in three German University Hospitals was assessed with respect to body measurements (length, weight, body mass index BMI, head circumference OFC), motor and cognitive development as well as genotype (site of mutation). Anthropometric measures and developmental data were compared to those of a reference population and deviations were analyzed for their frequency in the cohort as well as in relation to the genotypes. Corticosteroid therapy was implemented in 29 from 263 patients. Overall 30% of the patients exhibit a short statue (length development at 2-5 years of age, and this is even more prevalent when steroid therapy is applied (45% of patients with steroid therapy). The BMI shows a rightwards shift (68% > 50th centile) and the OFC a leftwards shift (65% development is delayed in a third of the patients (mean age at walking 18.3 months, 30% > 18 months, 8% > 24 months). Almost half of the patients show cognitive impairment (26% learning disability, 17% intellectual disability). Although there is no strict genotype-phenotype correlation, particularly mutations in the distal part of the dystrophin gene are frequently associated with short stature and a high rate of microcephaly as well as cognitive impairment.

  4. Acute muscular weakness in children

    Directory of Open Access Journals (Sweden)

    Ricardo Pablo Javier Erazo Torricelli

    Full Text Available ABSTRACT Acute muscle weakness in children is a pediatric emergency. During the diagnostic approach, it is crucial to obtain a detailed case history, including: onset of weakness, history of associated febrile states, ingestion of toxic substances/toxins, immunizations, and family history. Neurological examination must be meticulous as well. In this review, we describe the most common diseases related to acute muscle weakness, grouped into the site of origin (from the upper motor neuron to the motor unit. Early detection of hyperCKemia may lead to a myositis diagnosis, and hypokalemia points to the diagnosis of periodic paralysis. Ophthalmoparesis, ptosis and bulbar signs are suggestive of myasthenia gravis or botulism. Distal weakness and hyporeflexia are clinical features of Guillain-Barré syndrome, the most frequent cause of acute muscle weakness. If all studies are normal, a psychogenic cause should be considered. Finding the etiology of acute muscle weakness is essential to execute treatment in a timely manner, improving the prognosis of affected children.

  5. Informal caregivers of clients with neurological conditions: profiles, patterns and risk factors for distress from a home care prevalence study. (United States)

    Mitchell, Lori A; Hirdes, John; Poss, Jeff W; Slegers-Boyd, Caroline; Caldarelli, Hilary; Martin, Lynn


    Individuals living in the community with neurological conditions receive the majority of their care from informal caregivers. The purpose of this project was to provide a profile of caregivers of home care clients with neurological conditions. The study also examined prevalence of caregiver distress and the association between neurological conditions and other client and caregiver characteristics with distress. The study population included Canadian home care clients in the Winnipeg Regional Health Authority in Manitoba and in the province of Ontario. Clients with RAI-Home Care (RAI-HC) assessment data from 2003 to 2010 were examined. Neurological conditions of interest included Alzheimer's disease and related dementias, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease, Huntington disease, epilepsy, muscular dystrophy, cerebral palsy, traumatic brain injury, spinal cord injury, and stroke. Descriptive statistics were analyzed to describe home care client characteristics and caregiver characteristics for each neurological condition. Logistic regression analysis was used to identify risk factors associated with caregiver distress. A substantial proportion of home care clients were found to have one or more of the neurological conditions (38.8% to 41.9%). Caregiver distress was twice as prevalent among caregivers of clients with neurological conditions (28.0%). The largest associations with caregiver distress were the amount of informal care hours provided in a week and the MAPLe algorithm, an indicator of a client's level of priority for care. After adjustment for client characteristics, Huntington disease was the neurological condition most strongly associated with caregiver distress. However, clients' clinical characteristics and informal care hours had a stronger association with caregiver distress than the presence of a neurological condition. Provision of formal home care services provided a protective effect from caregiver distress

  6. The role of fibrosis in Duchenne muscular dystrophy




    Muscular dystrophies such as Duchenne muscular dystrophy (DMD) are usually approached as dysfunctions of the affected skeletal myofibres and their force transmission. Comparatively little attention has been given to the increase in connective tissue (fibrosis) which accompanies these muscular changes. Interestingly, an increase in endomysial tissue is apparent long before any muscular degeneration can be observed. Fibrosis is the result of a reactive or reparative process involving mechanical...

  7. Congenital neurogenic muscular atrophy in megaconial myopathy due to a mutation in CHKB gene. (United States)

    Castro-Gago, Manuel; Dacruz-Alvarez, David; Pintos-Martínez, Elena; Beiras-Iglesias, Andrés; Arenas, Joaquín; Martín, Miguel Ángel; Martínez-Azorín, Francisco


    Choline kinase beta gene (CHKB) mutations have been identified in Megaconial Congenital Muscular Dystrophy (MDCMC) patients, a very rare inborn error of metabolism with 21 cases reported worldwide. We report the case of a Spanish boy of Caucasian origin who presented a generalized congenital muscular hypotonia, more intense at lower limb muscles, mildly elevated creatine kinase (CK), serum aspartate transaminase (AST) and lactate. Electromyography (EMG) showed neurogenic potentials in the proximal muscles. Histological studies of a muscle biopsy showed neurogenic atrophy with enlarged mitochondria in the periphery of the fibers, and complex I deficiency. Finally, genetic analysis showed the presence of a homozygous mutation in the gene for choline kinase beta (CHKB: NM_005198.4:c.810T>A, p.Tyr270(∗)). We describe here the second Spanish patient whit mutation in CHKB gene, who despite having the same mutation, presented an atypical aspect: congenital neurogenic muscular atrophy progressing to a combined neuropathic and myopathic phenotype (mixed pattern).

  8. Sixth nerve palsy associated with obstruction in Dorello's canal, accompanied by nodular type muscular sarcoidosis. (United States)

    Shioya, Ayako; Takuma, Hiroshi; Shiigai, Masanari; Ishii, Akiko; Tamaoka, Akira


    A 52-year-old Japanese woman complaining of horizontal double vision for 10 days was admitted to our hospital. Neurological examination revealed left abducent nerve palsy and muscle swelling in her thighs. Brain MRI showed obstruction in the spinal fluid space of the left Dorello's canal, which transmits a portion of the abducent nerve. In Ga-67-enhanced citrate scintigraphy, wide accumulation was seen in her bilateral thighs, lower legs, and gluteus muscles. Muscular MRI showed a star-shaped central structure on short tau inversion recovery (STIR) images, and the three stripes sign on T2-weighted images. These MRI findings indicated nodular-type muscular sarcoidosis. A muscle biopsy from the quadriceps femoris showed granulomatous epithelioid giant cells and non-necrotizing chronic lymphadenitis, which also indicate sarcoidosis. Her condition was considered to be caused by sarcoid granulomas obstructing Dorello's canal. She was treated with oral prednisolone (1 mg·kg(-1)·day(-1)) and her symptoms and MRI findings improved. This is the first known report of abducent nerve impairment in Dorello's canal, other than fetal hypoplasia. Brain MRI, muscular MRI, and muscle biopsy are useful for the diagnosis of abducent nerve palsy, and it is important to consider Dorello's canal obstruction by sarcoidosis. Complete remission can be achieved with proper treatment. Copyright © 2014 Elsevier B.V. All rights reserved.

  11. [Deficiency, disability, neurology and cinema]. (United States)

    Collado-Vázquez, Susana; Cano de la Cuerda, Roberto; Jiménez-Antona, Carmen


    Cinema has been defined in many different ways, but most of them agree that it should be considered both a technique and an art. Although films often depict fantasy stories, in many cases they also reflect day-to-day realities. In its earliest days cinema was already attracted to the world of health and sickness, and frequently addressed topics like medical practice, how patients lived with their illnesses, bioethical issues, the relationship between physician and patient or research. To review the presence of neurological pathologies in the cinema with a view to identifying the main neurological disorders that have been portrayed in films. Likewise it also intends to describe the medical praxis that is employed, the relationship between physician and patient, how the experiences of the patient and the family are represented, the adaptation to social and occupational situations, and the intervention of other health care professionals related with neurological patients. Some of the most significant films that have addressed these topics were reviewed and it was seen that in some of them the illness is dealt with in a very true-to-life manner, whereas others tend to include a greater number of inaccuracies and a larger degree of fiction. Cinema has helped to shape certain ways of thinking about the health care professionals who work with neurological patients, the importance of support from the family and the social role, among other things. This confirms that resorting to cinematographic productions is a fruitful tool for stimulating a critical interest in the past and present of medical practice.

  12. Legal challenges in neurological practice

    Sita Jayalakshmi


    Full Text Available Clinical neuroscience has made tremendous advances over the last century. Neurology as a discipline is still considered challenging and at times risky due to the natural history and progressive course of few of the neurological diseases. Encouragingly, the patient and their caregivers are now increasingly willing to be actively involved in making decisions. The patients' relationship with the doctor is a reflection of the society. A society that is orienting itself toward “rating” and “feedback” has made this doctor–patient relationship, a consumer–service provider relationship. This perhaps is due to commercialization of health that usually accompanies globalization. Moreover, a rapid influx of information from potential erroneous sources such as the Internet has also made patient and caregivers not being hesitant to taking legal course in the case of adverse events during treatment or simply because of dissatisfaction. The purpose of the legal process initiated by patients with neurological ailments is more often to compensate for the income lost, physical and psychological anguish that accompanies disease and its treatment, and to fund treatment or rehabilitation requirements. However, it is not clearly established if monetary benefits acquired lead to better opportunities for recovery of the patient. The consumer protection act and commercialization of medical services may well have an adverse effect on the doctor and patient relationship. Hence, there is a great need for all medical professionals to mutually complement and update each other. This review examines legal (litigation processes with special interest on medicolegal system in patients with neurological ailments and the challenges faced by the neurologist during day-to-day clinical practice.

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

  16. Torture and its neurological sequelae. (United States)

    Moreno, A; Grodin, M A


    Refugees and asylum seekers continue to enter the United States and the European Union in record numbers. Some have estimated that between 5-35% of all refugees have suffered torture in their countries of origin. Although general practitioners and specialized physicians are likely to encounter victims of torture as patients, few providers are familiar with the health problems that may affect this patient population. :To provide neurologists, neurosurgeons, and rehabilitation medicine physicians with basic knowledge about survivors of torture that can help in the diagnosis, treatment, and referral of such patients. A MEDLINE (1966-October 2001) search using keywords torture and sequelae (nervous system diseases and brain injuries) was conducted. Other data sources included books, reference lists, online resources and expert opinion. :Forms of torture that may affect the nervous system include beatings, gunshot wounds, stab wounds, asphyxiation, prolonged suspension and electrocution. Victims of torture commonly experience neurological symptoms such as headaches, vertigo, loss of consciousness and dizziness during and after torture. A successful and meaningful clinical interaction with a survivor of torture includes avoiding retraumatization, building trust, spelling out any limits on confidentiality, and above anything else, establishing empathy with the patient. Neurological sequelae of torture can be devastating physically and psychologically. The treatment of these neurological conditions does not differ from other patient populations. However, the clinical approach is unique and must focus on avoiding retraumatization and helping the victim reintegrate into society as quickly as possible.

  17. Neurological complications of Schistosoma infection. (United States)

    Carod-Artal, Francisco Javier


    Schistosomiasis is a parasitic disease caused by blood flukes of the genus Schistosoma. Currently more than 200 million people worldwide are affected. Neuroschistosomiasis constitutes a severe presentation of the disease. Neurological symptoms result from the inflammatory response of the host to egg deposition in the brain and spinal cord. Neurological complications of cerebral schistosomiasis include delirium, loss of consciousness, seizures, dysphasia, visual field impairment, focal motor deficits and ataxia. Cerebral and cerebellar tumour-like neuroschistosomiasis can present with increased intracranial pressure, headache, nausea and vomiting, and seizures. Myelopathy (acute transverse myelitis and subacute myeloradiculopathy) is the most common neurological complication of Schistosoma mansoni infection. Schistosomal myelopathy tends to occur early after infection and is more likely to be symptomatic than cerebral schistosomiasis. The conus medullaris and cauda equina are the most common sites of involvement. Severe schistosomal myelopathy can provoke a complete flaccid paraplegia with areflexia, sphincter dysfunction and sensory disturbances. Schistosomicidal drugs, steroids and surgery are the currently available treatments for neuroschistosomiasis. Rehabilitation and multidisciplinary team care are needed in severely disabled patients.

  18. VEGF Signaling in Neurological Disorders

    Directory of Open Access Journals (Sweden)

    Joon W. Shim


    Full Text Available Vascular endothelial growth factor (VEGF is a potent growth factor playing diverse roles in vasculogenesis and angiogenesis. In the brain, VEGF mediates angiogenesis, neural migration and neuroprotection. As a permeability factor, excessive VEGF disrupts intracellular barriers, increases leakage of the choroid plexus endothelia, evokes edema, and activates the inflammatory pathway. Recently, we discovered that a heparin binding epidermal growth factor like growth factor (HB-EGF—a class of EGF receptor (EGFR family ligands—contributes to the development of hydrocephalus with subarachnoid hemorrhage through activation of VEGF signaling. The objective of this review is to entail a recent update on causes of death due to neurological disorders involving cerebrovascular and age-related neurological conditions and to understand the mechanism by which angiogenesis-dependent pathological events can be treated with VEGF antagonisms. The Global Burden of Disease study indicates that cancer and cardiovascular disease including ischemic and hemorrhagic stroke are two leading causes of death worldwide. The literature suggests that VEGF signaling in ischemic brains highlights the importance of concentration, timing, and alternate route of modulating VEGF signaling pathway. Molecular targets distinguishing two distinct pathways of VEGF signaling may provide novel therapies for the treatment of neurological disorders and for maintaining lower mortality due to these conditions.

  3. Disease Mechanisms and Therapeutic Approaches in Spinal Muscular Atrophy (United States)

    Tisdale, Sarah


    Motor neuron diseases are neurological disorders characterized primarily by the degeneration of spinal motor neurons, skeletal muscle atrophy, and debilitating and often fatal motor dysfunction. Spinal muscular atrophy (SMA) is an autosomal-recessive motor neuron disease of high incidence and severity and the most common genetic cause of infant mortality. SMA is caused by homozygous mutations in the survival motor neuron 1 (SMN1) gene and retention of at least one copy of the hypomorphic gene paralog SMN2. Early studies established a loss-of-function disease mechanism involving ubiquitous SMN deficiency and suggested SMN upregulation as a possible therapeutic approach. In recent years, greater knowledge of the central role of SMN in RNA processing combined with deep characterization of animal models of SMA has significantly advanced our understanding of the cellular and molecular basis of the disease. SMA is emerging as an RNA disease not limited to motor neurons, but one that involves dysfunction of motor circuits that comprise multiple neuronal subpopulations and possibly other cell types. Advances in SMA research have also led to the development of several potential therapeutics shown to be effective in animal models of SMA that are now in clinical trials. These agents offer unprecedented promise for the treatment of this still incurable neurodegenerative disease. PMID:26063904

    We examined the specific nerve conduction deficits distinguishing spinal muscular atrophy (SMA) subtypes I and II. Five SMA I patients (age, 0.2-1.1 years) and 10 SMA II patients (age, 1.0-2.8 years) were examined. Patients were compared to age-matched controls for motor and sensory conduction velocity (MCV and SCV) changes, compound muscle and sensory nerve action potential amplitudes (CMAP and SNAP), and F-wave occurrence (FO). Slower MCVs were found in three of five SMA I patients; all five exhibited markedly decreased CMAP amplitudes. Tibial nerve CMAP amplitudes significantly reduced in SMA II patients (pnerve of SMA II patients (p=0.031). Loss of motor units may be widespread in the early stage of SMA I, while specific to the legs in young SMA II patients. SMA I showed sensory nerve degeneration, especially of large myelinated fibers. SMA II showed no sensory nerve abnormalities. Copyright © 2012 The Japanese Society of Child Neurology. Published by Elsevier B.V. All rights reserved.

    To determine the prevalence and features of fatty liver disease in spinal and bulbar muscular atrophy (SBMA). Two groups of participants with SBMA were evaluated. In the first group, 22 participants with SBMA underwent laboratory analysis and liver imaging. In the second group, 14 participants with SBMA were compared to 13 female carriers and 23 controls. Liver biopsies were done in 4 participants with SBMA. Evidence of fatty liver disease was detected by magnetic resonance spectroscopy in all participants with SBMA in the first group, with an average dome intrahepatic triacylglycerol of 27% (range 6%-66%, ref ≤5.5%). Liver dome magnetic resonance spectroscopy measurements were significantly increased in participants with SBMA in the second group relative to age- and sex-matched controls, with average disease and male control measurements of 17% and 3%, respectively. Liver biopsies were consistent with simple steatosis in 2 participants and nonalcoholic steatohepatitis in 2 others. We observed evidence of nonalcoholic liver disease in nearly all of the participants with SBMA evaluated. These observations expand the phenotypic spectrum of the disease and provide a potential biomarker that can be monitored in future studies. Copyright © 2017 The Author(s).

  6. Cervical spinal canal narrowing and cervical neurologi-cal injuries

    Directory of Open Access Journals (Sweden)

    ZHANG Ling


    Full Text Available 【Abstract】Cervical spinal canal narrowing can lead to injury of the spinal cord and neurological symptoms in-cluding neck pain, headache, weakness and parasthesisas. According to previous and recent clinical researches, we investigated the geometric parameters of normal cervical spinal canal including the sagittal and transverse diameters as well as Torg ratio. The mean sagittal diameter of cervical spinal canal at C 1 to C 7 ranges from 15.33 mm to 20.46 mm, the mean transverse diameter at the same levels ranges from 24.45 mm to 27.00 mm and the mean value of Torg ratio is 0.96. With respect to narrow cervical spinal canal, the following charaterstics are found: firstly, extension of the cervical spine results in statistically significant stenosis as compared with the flexed or neutral positions; secondly, females sustain cervical spinal canal narrowing more easily than males; finally, the consistent narrowest cervical canal level is at C 4 for all ethnicity, but there is a slight variation in the sagittal diameter of cervical spinal stenosis (≤14 mm in Whites, ≤ 12 mm in Japanese, ≤13.7 mm in Chinese. Narrow sagittal cervical canal diameter brings about an increased risk of neurological injuries in traumatic, degenerative and inflam-matory conditions and is related with extension of cervical spine, gender, as well as ethnicity. It is hoped that this re-view will be helpful in diagnosing spinal cord and neuro-logical injuries with the geometric parameters of cervical spine in the future.

    Muscular hydatid disease is uncommon. It usually consists in a primary single cyst which remains asymptomatic. Diagnosis is made upon pathological examination after a surgical procedure carried out to establish the cause of a swelling. Indeed, in most cases serology is not helpful and, moreover, it rapidly becomes negative after surgery. We report two cases and discuss the features of this condition.

    Objective: We provide a nationwide population study of patients with congenital muscular dystrophy in Italy. Methods: Cases were ascertained from the databases in all the tertiary referral centers for pediatric neuromuscular disorders and from all the genetic diagnostic centers in which diagnostic tests for these forms are performed. Results: The study includes 336 patients with a point prevalence of 0.563 per 100,000. Mutations were identified in 220 of the 336 (65.5%). The cohort was subdivided into diagnostic categories based on the most recent classifications on congenital muscular dystrophies. The most common forms were those with α-dystroglycan glycosylation deficiency (40.18%) followed by those with laminin α2 deficiency (24.11%) and collagen VI deficiency (20.24%). The forms of congenital muscular dystrophy related to mutations in SEPN1 and LMNA were less frequent (6.25% and 5.95%, respectively). Conclusions: Our study provides for the first time comprehensive epidemiologic information and point prevalence figures for each of the major diagnostic categories on a large cohort of congenital muscular dystrophies. The study also reflects the diagnostic progress in this field with an accurate classification of the cases according to the most recent gene discoveries. PMID:25653289

    This paper explores the relationship between neurology and psychiatry. It marshals evidence that disorders of the brain typically have neurological and psychological-cognitive, affective, behavioural-manifestations, while disorders of the psyche are based in the brain. Given the inseparability of neurological and psychiatric disorders, their disease classifications should eventually fuse, and joint initiatives in training, service and research should be strongly encouraged.

    Pareyson, Davide; Fratta, Pietro; Pradat, Pierre-François


    Pathomechanisms of spinal and bulbar muscular atrophy (SBMA) have been extensively investigated and are partially understood, but no effective treatment is currently available for this disabling disorder. Its rarity, the slow disease progression, and lack of sensitive-to-change outcome measures...... as possible can be included, with the following aims: facilitate planning of clinical trials and recruitment of patients, define natural history of the disease, characterize epidemiology, develop standards of care, and inform the community of patients about research progresses and ongoing trials. We also aim...

  4. [Deficiency, disability, neurology and art]. (United States)

    Cano de la Cuerda, Roberto; Collado-Vazquez, Susana


    Disability is a complex phenomenon, and the ways it has been conceived, explained and treated have varied notably throughout history. As the years go by, human beings have evolved and, at the same time, so have medicine and art. And therein lies the extraordinary value, from the ontological point of view, of many works of art, which would never have been produced without the intervention of disease and the practice of the medical art. The aim of this work is to address the study of some deficiencies, disabilities and neurological pathologies that have been represented in paintings at different times in history. This article begins with the study of pictures that deal with dwarves and other misnamed freaks of nature that have been represented by painters from Velazquez to Titian or Rubens. The study looks at paintings of cripples, pictures containing the mentally disabled, with examples by Bruegel the Elder or Munch, as well as certain neurological disorders that have been portrayed in paintings, such as Escaping criticism by Pere Borrell or Sad inheritance by Sorolla. Likewise, we also reflect on the trite concept of disease and artistic creativity. The artistic representation of deficiency and disability has evolved in parallel to the feelings of men and women in each period of history and, at the same time, their social evolution. Nowadays, this concept continues to advance and some artists no longer represent the sick person, but instead the illness itself.

    Zara, Gabriella; Codemo, Valentina; Palmieri, Arianna; Schiff, Sami; Cagnin, Annachiara; Citton, Valentina; Manara, Renzo


    Hyperemesis gravidarum can impair correct absorption of an adequate amount of thiamine and can cause electrolyte imbalance. This study investigated the neurological complications in a pregnant woman with hyperemesis gravidarum. A 29-year-old pregnant woman was admitted for hyperemesis gravidarum. Besides undernutrition, a neurological examination disclosed weakness with hyporeflexia, ophthalmoparesis, multidirectional nystagmus and optic disks swelling; the patient became rapidly comatose. Brain MRI showed symmetric signal hyperintensity and swelling of periaqueductal area, hypothalamus and mammillary bodies, medial and posterior portions of the thalamus and columns of fornix, consistent with Wernicke encephalopathy (WE). Neurophysiological studies revealed an axonal sensory-motor polyneuropathy, likely due to thiamine deficiency or critical illness polyneuropathy. Sodium and potassium supplementation and parenteral thiamine were administered with improvement of consciousness state in a few days. WE evolved in Korsakoff syndrome. A repeat MRI showed a marked improvement of WE-related alterations and a new hyperintense lesion in the pons, suggestive of central pontine myelinolysis. No sign or symptom due to involvement of the pons was present.

    Full Text Available A part from the well-established syndrome of motor paralysis, hypokalemia may present with atypical neurological manifestations, which are not well documented in literature. Methods: We treated 30 patients of hypokalemia whose neurological manifestations improved after corrections of hypokalemia. A retrospective chart review of the clinical profile was done with emphasis on the evolution of symptoms and occurrence of unusual manifestations. Results: Twenty-eight patients had subacute quadriparesis with duration of symptoms varying from 10hrs to 7 days and two had slowly progressive quadriparesis. Fifty percent of patients had more than one attack of paralysis. Early asymmetric weakness (11, stiffness and abnormal posture of hands (7, predominant bibrachial weakness (4, distal paresthesias (4, hemiparesthesia (1, hyperreflexia(4, early severe weakness of neck muscles (3, chorea (1, trismus (1,and, retention of urine (1 were the unusual features observed. The means level of serum potassium on admission was 2.1+0.6mEq/L.and the serum creatine kinase was elevated in 14 out of 17 patients. All patients except two had complete recovery.

  7. Neurological disorders in hypertensive patients

    Directory of Open Access Journals (Sweden)

    N. V. Vakhnina


    Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

  8. Surgeon-level reporting presented by funnel plot is understood by doctors but inaccurately interpreted by members of the public. (United States)

    Bhalla, Ashish; Mehrotra, Prerna; Amawi, Falah; Lund, Jonathan N


    Risk-adjusted outcome data for general surgeons practicing in the United Kingdom were published for the first time in 2013 with the aim of increasing transparency, improving standards, and providing the public with information to aid decision making. Most specialties used funnel plots to present their data. We assess the ability of members of the public (MoP), medical students, nonsurgical doctors (NSD), and surgeons to understand risk-adjusted surgical outcome data. A fictitious outcome dataset was created and presented in the form of a funnel plot to 10 participants from each of the aforementioned group. Standard explanatory text was provided. Each participant was given 5 minutes to review the funnel plot and complete a questionnaire. For each question, there was only 1 correct answer. Completion rate was 100% (n = 40). No difference existed between NSD and surgeons. A significant difference for identification of the "worst performing surgeon" was noted between surgeons and MoP (p funnel plot significantly "more difficult" to interpret than surgeons did (p < 0.01) and NSD (p < 0.01). MoP found these data significantly more "difficult to understand" and were less likely to both spot "outliers" and use this data to inform decisions than doctors. Surgeons should be aware that outcome data may require an alternative method of presentation to be understood by MoP. Copyright © 2015 Association of Program Directors in Surgery.

    Talita Dias da Silva

    Full Text Available ABSTRACT Duchenne muscular dystrophy (DMD is an X-linked recessive disorder, characterized by progressive muscle weakness. Historically, pain has not been considered to be a major symptom in DMD. Objective To investigate the relationship between DMD and pain. Methods We conducted a systematic review in Medline/PubMed and BVS (virtual library in health databases. We searched for articles that showed the terms “Muscular Dystrophy, Duchenne” and “Pain” in all fields. All studies included boys diagnosed with DMD and the occurrence/amount of pain on this population. Results Initially, there were 175 studies. 167 articles were excluded for not meeting the inclusion criteria. The remaining eight eligible studies, involving pain assessment in DMD, were analyzed. Conclusion Pain is a frequent problem in this population and this symptom is potentially tractable. Studies conclude that pain can directly influence the quality of life of this population.

  10. Sleep Disordered Breathing in Duchenne Muscular Dystrophy. (United States)

    LoMauro, Antonella; D'Angelo, Maria Grazia; Aliverti, Andrea


    This review aims to explain the inevitable imbalance between respiratory load, drive, and muscular force that occurs in the natural aging of Duchenne muscular dystrophy and that predisposes these patients to sleep disordered breathing (SDB). In DMD, SDB is characterized by oxygen desaturation, apneas, hypercapnia, and hypoventilation during sleep and ultimately develops into respiratory failure during wakefulness. It can be present in all age groups. Young patients risk obstructive apneas because of weight gain, secondary to progressive physical inactivity and prolonged corticosteroid therapy; older patients hypoventilate and desaturate because of respiratory muscle weakness, in particular the diaphragm. These conditions are further exacerbated during REM sleep, the phase of maximal muscle hypotonia during which the diaphragm has to provide most of the ventilation. Evidence is given to the daytime predictors of early symptoms of SDB, important indicators for the proper time to initiate mechanical ventilation.

  11. [Comparative analysis of the neurological status in patients with lumbar discopathy receiving conservative or operative therapies]. (United States)

    Radziszewski, Krzysztof Roch


    Neurological examination is one of basic assessment methods of the patients with discopathy of the lumbar spine. Neurological status of the patients can significantly change depending on progression of the disease of the intervertebral disc. It often determines a selection of the treatment method; it is also important criterion for assessment of efficacy of the accepted procedure. The aim of this study was to retrospectively evaluate neurological status in the patients with lumbar discopathy receiving only conservative therapy as well as undergoing surgical procedures. 665 patients aged between 16 and 76 years with discopathy at L4-L5 and L5-S1 levels have been enrolled to the study. In estimated group 348 patients received only a conservative therapy whereas 317 patients undergone an operative procedure. Study included hospitalization period and more than ten year period after discharge from the Clinic. Collected material has been analyzed in tree age groups: young persons (up to 30), mid age persons (31-50 years) and older persons (at the age of above 50). Neurological examination included analysis of the following parameters: cough symptom, Laségue's sign, stretch reflexes (patellar, ankle), superficial perception and vibration, function of sphincters, muscular power). No significant progression of the neurological symptoms up to the fifth year of treatment has been seen in group of patients receiving conservative therapy. In group of operated patients starting the second year after surgical procedure, number of diagnosed pathological neurological symptoms systematically was increasing. Patients at the age above 50 presented significantly higher level of neurological disturbances than young and patients in mid age. In the baseline study, level of diagnosed neurological disturbances in group of patients referred to surgical procedure was significantly higher than in group of patients receiving only conservative therapy. Conservative treatment and operative

According to our experiences to DMD rehabilitation therapy, we reviewed the progress of DMD rehabilitation therapy. It includes the clinical stages and characteristics of DMD, the general principle and th...

  14. Urological manifestations of Duchenne muscular dystrophy. (United States)

    Askeland, Eric J; Arlen, Angela M; Erickson, Bradley A; Mathews, Katherine D; Cooper, Christopher S


    Duchenne muscular dystrophy is a dystrophinopathy affecting males that is associated with multiple organ system complications. To our knowledge urological complications of Duchenne muscular dystrophy have been described only anecdotally to date. We reviewed the medical charts of 135 patients with Duchenne or Duchenne-Becker muscular dystrophy for demographics and disease progression, urological diagnoses, intervention and followup. Of 135 patients 67 (50%) had at least 1 documented urological diagnosis and 38 (28%) had multiple manifestations. Lower urinary tract symptoms were the most common urological diagnosis (32% of patients). Survival analysis revealed a median age at onset of lower urinary tract symptoms of 23 years (95% CI 17.7-23.9). Intervention was required in 12 patients (9%), most commonly due to nephrolithiasis. Urological morbidity increased with Duchenne muscular dystrophy progression when stratified by clinical progression. Lower urinary tract symptoms were more common in nonambulatory patients (40.7% vs 19%, p = 0.007), those with a diagnosis of scoliosis (44% vs 19.7%, p = 0.003) and/or scoliosis spine surgery (60% vs 22%, p <0.001), and those on invasive respiratory support (53% vs 29%, p = 0.046). Likewise, nephrolithiasis was more common in nonambulatory patients (10% vs 0%, p = 0.017), those with scoliosis (12% vs 0%, p = 0.004) and/or scoliosis spine surgery (20% vs 1%, p <0.001), and those on invasive respiratory support (29% vs 3%, p <0.001). Only 28% of patients with a urological manifestation were referred to urology. As these patients transition into adolescence and adulthood, the increased prevalence of urological manifestations warrants increased awareness and referral to urologists.

    Cysticercosis is a parasitic disease caused by a worm of the Cestoda class. The most prevalent form affects the nervous system. This case report is from a 78-year old female patient evaluated at Clinica Mult Imagem, in the city of Santos, Brazil, who presented a form of the disease that differed from the classic neurocysticercosis, in this case muscular cysticercosis. This and other forms of manifestation justify further studies to ensure adequate recognition, diagnosis and treatment of this parasitic disease. (author)

  16. Proximal spinal muscular atrophy: current orthopedic perspective

    Directory of Open Access Journals (Sweden)

    Haaker G


    Full Text Available Gerrit Haaker, Albert Fujak Department of Orthopaedic Surgery, Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany Abstract: Spinal muscular atrophy (SMA is a hereditary neuromuscular disease of lower motor neurons that is caused by a defective "survival motor neuron" (SMN protein that is mainly associated with proximal progressive muscle weakness and atrophy. Although SMA involves a wide range of disease severity and a high mortality and morbidity rate, recent advances in multidisciplinary supportive care have enhanced quality of life and life expectancy. Active research for possible treatment options has become possible since the disease-causing gene defect was identified in 1995. Nevertheless, a causal therapy is not available at present, and therapeutic management of SMA remains challenging; the prolonged survival is increasing, especially orthopedic, respiratory and nutritive problems. This review focuses on orthopedic management of the disease, with discussion of key aspects that include scoliosis, muscular contractures, hip joint disorders, fractures, technical devices, and a comparative approach of conservative and surgical treatment. Also emphasized are associated complications including respiratory involvement, perioperative care and anesthesia, nutrition problems, and rehabilitation. The SMA disease course can be greatly improved with adequate therapy with established orthopedic procedures in a multidisciplinary therapeutic approach.

  17. [Quantitative echographic assessment of muscular physiopathology]. (United States)

    Talia, B; Casini, A; Fabbri, F; Lotti, F; Masotti, L


    The evaluation of muscular contraction is one of the main variables in muscular reeducation treatment protocols. US depicts muscular structure and size, as well as changes in both. A real-time US unit with 5/7.5 MHz probes and a computer with advanced software were used; the US unit was modified so as to reduce scanning times and to yield a high number of images/second (about 45). During endoscopy, a higher number of intermediate positions can thus be found between rest and contraction, which yields more statistically significant results. The US unit is connected to a video-recorder and to an electrostimulator to obtain isometric and isotonic contractions; the latter unit is connected to the US unit so that the electric and the US energies can be emitted simultaneously and the synchronism of the contraction and of the beginning of the electric stimulation can be assessed. Besides normal control subjects, patients with hypotrophic recto-femoral muscle were examined: the results were collected in a databank useful to choose the most appropriate treatment, to follow patients during therapy, to evaluate the final results and finally to be used in sports activities.

  18. Management of myocardial damage in muscular dystrophy

    International Nuclear Information System (INIS)

    Tamura, Takuhisa


    Heart failure (HF) is a fatal complication in many muscular dystrophy cases and has become the most common cause of death in Duchenne muscular dystrophy (DMD) since 2001. HF deaths in DMD occur in young patients and increase, along with respiratory failure, in older patients. Managing HF, therefore, is the most important component of DMD treatment. Management of HF is necessary in DMD patients of all ages because myocardial damage progresses regardless of age and disability. Electrocardiography, echocardiography, myocardial single-photon emission computed tomography (SPECT), and natriuretic peptides are used for the diagnosis of myocardial damage and chronic HF. Tissue Doppler echocardiography is in particularly useful for early detection of minute myocardial damage and dysfunction in DMD. The first-line drugs for chronic HF are angiotensin-converting enzyme inhibitors, and the prognosis of DMD patients has been improved using these drugs and beta-blockers. Diuretics are added in the presence of pulmonary congestion. Digoxin is most effective at a blood level of 0.5-0.8 ng/mL because of its pharmacokinetics in DMD. Surgical treatment may be necessary in cases of intractable HF. Cardiac resynchronization therapy (biventricular pacing), a treatment with an artificial pacemaker, is indicated for cases that meet specific criteria, including HF with ventricular dyssynchrony. Applications of partial left ventriculectomy (Batista procedure) and left ventricular assist devices in muscular dystrophy are likely in the near future. (author)

  19. Gene therapy for Duchenne muscular dystrophy. (United States)

    Verhaart, Ingrid E C; Aartsma-Rus, Annemieke


    Duchenne muscular dystrophy is a severe neuromuscular disorder for which there is currently no cure. Years of research have come to fruition during the past 18 months with publications on clinical trials for several gene therapy approaches for Duchenne muscular dystrophy. This review covers the present status of these approaches. The exon skipping approach is most advanced in the process of clinical application. Encouraging results have been obtained in two systemic clinical trials and further optimization has increased delivery to the heart in animal models. Limitations of the approach are the mutation-specificity and the anticipated requirement for lifelong treatment. Gene therapy by means of gene transfer holds the promise of more long-lasting effects. Results of a first, early-stage gene therapy trial, using viral vectors to deliver a minidystrophin gene, were reported. Animal studies suggest that it may be possible to overcome the main challenges currently facing gene therapy (immunogenicity of the vector and systemic body-wide delivery). Significant steps have been made in the development of gene therapy approaches for Duchenne muscular dystrophy. These approaches aim to slow down disease progression, requiring robust outcome measures to assess efficacy.

    Full Text Available This state-of-the art paper focuses on the poorly explored issue of foreign language aptitude, attempting to present the latest developments in this field and reconceptualizations of the construct from the perspective of neuroscience. In accordance with this goal, it first discusses general directions in neurolinguistic research on foreign language aptitude, starting with the earliest attempts to define the neurological substrate for talent, sources of difficulties in the neurolinguistic research on foreign language aptitude and modern research methods. This is followed by the discussion of the research on the phonology of foreign language aptitude with emphasis on functional and structural studies as well as their consequences for the knowledge of the concept. The subsequent section presents the studies which focus on lexical and morphosyntactic aspects of foreign language aptitude. The paper ends with a discussion of the limitations of contemporary research, the future directions of such research and selec ed methodological issues.

  1. Conflict Prevalence in Primary School and How It Is Understood to Affect Teaching and Learning in Ghana

    Directory of Open Access Journals (Sweden)

    Nana Afia Amponsaa Opoku-Asare


    Full Text Available Verbal and non-verbal interactions that occur daily between teachers and headteachers, teachers and pupils, and among pupils can generate conflict that may adversely affect teaching, learning, and schooling effectiveness. Little attention is, however, paid to the quality of relationships that exists between teachers and pupils, among teachers, among pupils, between teachers and their school heads, and between schools and their local communities. This study sought to investigate conflict prevalence in Ghana’s primary schools, and how relationship conflict is understood to affect teaching and learning at the level of headteachers as administrators, teachers as classroom managers, and pupils as learners, and direct beneficiaries of primary education. Using data gathered via interview, questionnaire administration, and observation in 30 public primary schools in 10 circuits of one district of Ashanti Region, the findings revealed a high prevalence of fighting, heckling, bullying, and other forms of relationship conflict among pupils; strained teacher–pupil relations due to insolence, indiscipline, and use of offensive language; and teacher–parent arguments and quarrels due to harsh punishment and verbal assault of pupils. Teacher–pupil conflicts may extend to teachers excluding the affected pupils from teaching and learning activities, denying them the rights to ask and answer questions, and have their class exercises marked, leading to lowered pupil self-esteem, reduced concentration during lessons, and passive involvement in learning activities, which could result in truancy and school dropout. Strengthening guidance mechanisms and encouraging peer mediation could significantly curb conflict in school environments and thereby raise educational standards in the district.

  2. Limiting exercise inhibits neuronal recovery from neurological disorders

    Directory of Open Access Journals (Sweden)

    Stefan S Anthony


    Full Text Available Patients who are bedridden often suffer from muscular atrophy due to reduced daily activities and can become depressed. However, patients who undergo physical therapy sometimes demonstrate positive benefits including a reduction of stressful and depressed behavior. Regenerative medicine has seen improvements in two stem cell-based therapies for central nervous system disorders. One therapy is through the transfer of exogenous stem cells. The other therapy is a more natural method and focuses on the increasing endogenous neurogenesis and restoring the neurological impairments. This study overviews how immobilization-induced disuse atrophy affects neurogenesis in rats, specifically hypothesizing that immobilization diminishes circulating trophic factor levels, like vascular endothelial growth factors or brain-derived neurotrophic factor, which in turn limits neurogenesis. This hypothesis requires the classification of the stem cell microenvironment by probing growth factors in addition to other stress-related proteins that correlate with exercise-induced neurogenesis. There is research examining the effects of increased exercise on neurogenesis while limiting exercise, which better demonstrates the pathological states of immobile stroke patients, remains relatively unexplored. To examine the effects of immobilization on neurogenesis quantitative measurements of movements, 5-bromo-2deoxyuridine labeling of proliferative cells, biochemical assays of serum, cerebrospinal fluid and neurological levels of trophic factors, growth factors, and stress-related proteins will indicate levels of neurogenesis. In further research, studies are needed to show how in vivo stimulation, or lack thereof, affects stem cell microenvironments to advance treatment procedures for strengthening neurogenesis in bedridden patients. This paper is a review article. Referred literature in this paper has been listed in the references section. The datasets supporting the

  3. Neuroimaging distinction between neurological and psychiatric disorders. (United States)

    Crossley, Nicolas A; Scott, Jessica; Ellison-Wright, Ian; Mechelli, Andrea


    It is unclear to what extent the traditional distinction between neurological and psychiatric disorders reflects biological differences. To examine neuroimaging evidence for the distinction between neurological and psychiatric disorders. We performed an activation likelihood estimation meta-analysis on voxel-based morphometry studies reporting decreased grey matter in 14 neurological and 10 psychiatric disorders, and compared the regional and network-level alterations for these two classes of disease. In addition, we estimated neuroanatomical heterogeneity within and between the two classes. Basal ganglia, insula, sensorimotor and temporal cortex showed greater impairment in neurological disorders; whereas cingulate, medial frontal, superior frontal and occipital cortex showed greater impairment in psychiatric disorders. The two classes of disorders affected distinct functional networks. Similarity within classes was higher than between classes; furthermore, similarity within class was higher for neurological than psychiatric disorders. From a neuroimaging perspective, neurological and psychiatric disorders represent two distinct classes of disorders. © The Royal College of Psychiatrists 2015.

  4. Endocrine disorders and the neurologic manifestations

    Directory of Open Access Journals (Sweden)

    Jeesuk Yu


    Full Text Available The nervous system and the endocrine system are closely interrelated and both involved intimately in maintaining homeostasis. Endocrine dysfunctions may lead to various neurologic manifestations such as headache, myopathy, and acute encephalopathy including coma. It is important to recognize the neurologic signs and symptoms caused by the endocrine disorders while managing endocrine disorders. This article provides an overview of the neurologic manifestations found in various endocrine disorders that affect pediatric patients. It is valuable to think about 'endocrine disorder' as a cause of the neurologic manifestations. Early diagnosis and treatment of hormonal imbalance can rapidly relieve the neurologic symptoms. Better understanding of the interaction between the endocrine system and the nervous system, combined with the knowledge about the pathophysiology of the neurologic manifestations presented in the endocrine disorders might allow earlier diagnosis and better treatment of the endocrine disorders.

  5. Threatened masculinity and muscularity: an experimental examination of multiple aspects of muscularity in men. (United States)

    Hunt, Christopher John; Gonsalkorale, Karen; Murray, Stuart B


    Two studies examined the threatened masculinity theory of male body dissatisfaction, which posits that threats to masculinity result in increased muscle dissatisfaction. In Study 1, a masculinity threat was followed by tasks examining confidence in physical ability and perceptions of current and ideal body shapes. Results showed that men who experienced a masculinity threat reported lower confidence in their physical ability and perceived themselves as less muscular than men who experienced an affirmation of their masculinity. In Study 2, men were asked to report their intention to increase muscularity and their appearance anxiety following a threat to masculinity. Results showed that men reported lower appearance anxiety and drive for muscularity when their masculinity was threatened than when their masculinity was affirmed. This apparent contradiction can be explained by noting that men may be motivated to deny appearance concerns following a threat to masculinity, as such concerns are equated with femininity.

    Cheuk, Daniel K L; Wong, Virginia; Wraige, Elizabeth; Baxter, Peter; Cole, Ashley


    Scoliosis in people with Duchenne muscular dystrophy is usually progressive and treated with surgery. However, it is unclear whether the existing evidence is sufficiently scientifically rigorous to support a recommendation for spinal surgery for most people with Duchenne muscular dystrophy and scoliosis. This is an updated review and an updated search was undertaken in which no new studies were found. To determine the effectiveness and safety of spinal surgery in people with Duchenne muscular dystrophy with scoliosis. We intended to test whether spinal surgery is effective in increasing survival, improving respiratory function, improving quality of life and overall functioning; and whether spinal surgery is associated with severe adverse effects. We searched the specialized registers of the Cochrane Neuromuscular Disease Group (31 July 2012), MEDLINE (January 1966 to July 2012), EMBASE (January 1947 to July 2012), CENTRAL (2012, Issue 7 in the Cochrane Library), CINAHL Plus(January 1937 to July 2012), Proquest Dissertation and Thesis Database (January 1980 to July 2012), and the National Institute of Health Clinical Trials Database (July 2012). No language restrictions were imposed. We planned to include controlled clinical trials using random or quasi-random allocation of treatment evaluating all forms of spinal surgery for scoliosis in people with Duchenne muscular dystrophy in the review. The control interventions would have been no treatment, non-operative treatment, or a different form of spinal surgery. Two authors independently examined the search results and evaluated the study characteristics against inclusion criteria to decide which ones would be included in the review. On searching, 47 studies were relevant but none met the inclusion criteria for the review, because they were not clinical trials but prospective or retrospective reviews of case series. Since there were no randomized controlled clinical trials available to evaluate the effectiveness of

  10. Clinical trial network for the promotion of clinical research for rare diseases in Japan: muscular dystrophy clinical trial network. (United States)

    Shimizu, Reiko; Ogata, Katsuhisa; Tamaura, Akemi; Kimura, En; Ohata, Maki; Takeshita, Eri; Nakamura, Harumasa; Takeda, Shin'ichi; Komaki, Hirofumi


    Duchenne muscular dystrophy (DMD) is the most commonly inherited neuromuscular disease. Therapeutic agents for the treatment of rare disease, namely "orphan drugs", have recently drawn the attention of researchers and pharmaceutical companies. To ensure the successful conduction of clinical trials to evaluate novel treatments for patients with rare diseases, an appropriate infrastructure is needed. One of the effective solutions for the lack of infrastructure is to establish a network of rare diseases. To accomplish the conduction of clinical trials in Japan, the Muscular dystrophy clinical trial network (MDCTN) was established by the clinical research group for muscular dystrophy, including the National Center of Neurology and Psychiatry, as well as national and university hospitals, all which have a long-standing history of research cooperation. Thirty-one medical institutions (17 national hospital organizations, 10 university hospitals, 1 national center, 2 public hospitals, and 1 private hospital) belong to this network and collaborate to facilitate clinical trials. The Care and Treatment Site Registry (CTSR) calculates and reports the proportion of patients with neuromuscular diseases in the cooperating sites. In total, there are 5,589 patients with neuromuscular diseases in Japan and the proportion of patients with each disease is as follows: DMD, 29 %; myotonic dystrophy type 1, 23 %; limb girdle muscular dystrophy, 11 %; Becker muscular dystrophy, 10 %. We work jointly to share updated health care information and standardized evaluations of clinical outcomes as well. The collaboration with the patient registry (CTSR), allows the MDCTN to recruit DMD participants with specific mutations and conditions, in a remarkably short period of time. Counting with a network that operates at a national level is important to address the corresponding national issues. Thus, our network will be able to contribute with international research activity, which can lead to

    Abdullah Tolaymat


    Full Text Available Sleep problems are frequently addressed as a primary or secondary concern during the visit to the pediatric neurology clinic. Sleep disorders can mimic other neurologic diseases (e.g., epilepsy and movement disorders, and this adds challenges to the diagnostic process. Sleep disorders can significantly affect the quality of life and functionality of children in general and those with comorbid neurological diseases in particular. Understanding the pathophysiology of sleep disorders, recognizing the implications of sleep disorder in children with neurologic diseases and behavioral difficulties, and early intervention continue to evolve resulting in better neurocognitive outcomes.

  14. Recent developments in the treatment of Duchenne muscular dystrophy and spinal muscular atrophy (United States)

    Liew, Wendy K. M.


    Pediatric neuromuscular disorders comprise a large variety of disorders that can be classified based on their neuroanatomical localization, patterns of weakness, and laboratory test results. Over the last decade, the field of translational research has been active with many ongoing clinical trials. This is particularly so in two common pediatric neuromuscular disorders: Duchenne muscular dystrophy and spinal muscular atrophy. Although no definitive therapy has yet been found, numerous active areas of research raise the potential for novel therapies in these two disorders, offering hope for improved quality of life and life expectancy for affected individuals.

  15. Management of scoliosis in patients with Duchenne muscular dystrophy and spinal muscular atrophy: A literature review. (United States)

    Garg, Sumeet


    Scoliosis occurs in nearly all non-ambulatory children with spinal muscular atrophy (SMA) and Duchenne muscular dystrophy (DMD). Non-operative treatments have not been shown to be effective at preventing progression of scoliosis. Progressive scoliosis can impact the ability of patients to sit comfortably, be cosmetically unappealing, and in severe cases exacerbate pulmonary disease. The main goal of operative treatment is to improve sitting balance and prevent progression of scoliosis. Complication rates are high and there is little data on effect of operative treatment on quality of life in children with SMA and DMD. Comprehensive multi-disciplinary pre-operative evaluations are vital to reduce the risks of operative treatment.

  18. Dysphagia in Duchenne muscular dystrophy: practical recommendations to guide management. (United States)

    Toussaint, Michel; Davidson, Zoe; Bouvoie, Veronique; Evenepoel, Nathalie; Haan, Jurn; Soudon, Philippe


    Duchenne muscular dystrophy (DMD) is a rapidly progressive neuromuscular disorder causing weakness of the skeletal, respiratory, cardiac and oropharyngeal muscles with up to one third of young men reporting difficulty swallowing (dysphagia). Recent studies on dysphagia in DMD clarify the pathophysiology of swallowing disorders and offer new tools for its assessment but little guidance is available for its management. This paper aims to provide a step-by-step algorithm to facilitate clinical decisions regarding dysphagia management in this patient population. This algorithm is based on 30 years of clinical experience with DMD in a specialised Centre for Neuromuscular Disorders (Inkendaal Rehabilitation Hospital, Belgium) and is supported by literature where available. Dysphagia can worsen the condition of ageing patients with DMD. Apart from the difficulties of chewing and oral fragmentation of the food bolus, dysphagia is rather a consequence of an impairment in the pharyngeal phase of swallowing. By contrast with central neurologic disorders, dysphagia in DMD accompanies solid rather than liquid intake. Symptoms of dysphagia may not be clinically evident; however laryngeal food penetration, accumulation of food residue in the pharynx and/or true laryngeal food aspiration may occur. The prevalence of these issues in DMD is likely underestimated. There is little guidance available for clinicians to manage dysphagia and improve feeding for young men with DMD. This report aims to provide a clinical algorithm to facilitate the diagnosis of dysphagia, to identify the symptoms and to propose practical recommendations to treat dysphagia in the adult DMD population. Implications for Rehabilitation Little guidance is available for the management of dysphagia in Duchenne dystrophy. Food can penetrate the vestibule, accumulate as residue or cause aspiration. We propose recommendations and an algorithm to guide management of dysphagia. Penetration/residue accumulation

    Infantile-onset spinal muscular atrophy (SMA) is the most common genetic cause of infant mortality, typically resulting in death preceding age 2. Clinical trials in this population require an understanding of disease progression and identification of meaningful biomarkers to hasten therapeutic development and predict outcomes. A longitudinal, multicenter, prospective natural history study enrolled 26 SMA infants and 27 control infants aged <6 months. Recruitment occurred at 14 centers over 21 months within the NINDS-sponsored NeuroNEXT (National Network for Excellence in Neuroscience Clinical Trials) Network. Infant motor function scales (Test of Infant Motor Performance Screening Items [TIMPSI], The Children's Hospital of Philadelphia Infant Test for Neuromuscular Disorders, and Alberta Infant Motor Score) and putative physiological and molecular biomarkers were assessed preceding age 6 months and at 6, 9, 12, 18, and 24 months with progression, correlations between motor function and biomarkers, and hazard ratios analyzed. Motor function scores (MFS) and compound muscle action potential (CMAP) decreased rapidly in SMA infants, whereas MFS in all healthy infants rapidly increased. Correlations were identified between TIMPSI and CMAP in SMA infants. TIMPSI at first study visit was associated with risk of combined endpoint of death or permanent invasive ventilation in SMA infants. Post-hoc analysis of survival to combined endpoint in SMA infants with 2 copies of SMN2 indicated a median age of 8 months at death (95% confidence interval, 6, 17). These data of SMA and control outcome measures delineates meaningful change in clinical trials in infantile-onset SMA. The power and utility of NeuroNEXT to provide "real-world," prospective natural history data sets to accelerate public and private drug development programs for rare disease is demonstrated.

  20. Endocannabinoid System in Neurological Disorders. (United States)

    Ranieri, Roberta; Laezza, Chiara; Bifulco, Maurizio; Marasco, Daniela; Malfitano, Anna M


    Several studies support the evidence that the endocannabinoid system and cannabimimetic drugs might have therapeutic potential in numerous pathologies. These pathologies range from neurological disorders, atherosclerosis, stroke, cancer to obesity/metabolic syndrome and others. In this paper we review the endocannabinoid system signaling and its alteration in neurodegenerative disorders like multiple sclerosis, Alzheimer's disease, Parkinson's disease and Huntington's disease and discuss the main findings about the use of cannabinoids in the therapy of these pathologies. Despite different etiologies, neurodegenerative disorders exhibit similar mechanisms like neuro-inflammation, excitotoxicity, deregulation of intercellular communication, mitochondrial dysfunction and disruption of brain tissue homeostasis. Current treatments ameliorate the symptoms but are not curative. Interfering with the endocannabinoid signaling might be a valid therapeutic option in neuro-degeneration. To this aim, pharmacological intervention to modulate the endocannabinoid system and the use of natural and synthetic cannabimimetic drugs have been assessed. CB1 and CB2 receptor signaling contributes to the control of Ca2+ homeostasis, trophic support, mitochondrial activity, and inflammatory conditions. Several studies and patents suggest that the endocannabinoid system has neuro-protective properties and might be a target in neurodegenerative diseases.

    Full Text Available Treatment of developmental disorders, correction of learning disabilities and behavioral problems in children should be prompt, complex and include pharmacotherapy with nootropic agents. The results of recent studies shown in this review proved effectiveness of pharmacotherapy with pyritinol in children with perinatal injury of central nervous system and its consequences, psychomotor and speech development delay, dyslexia, attention deficit/hyperactivity disorder, cognitive disorders and learning disabilities (including manifestations of epilepsy, chronic tic disorders and Tourette syndrome. Due to its ability to optimize metabolic processes in central nervous system, pyritinol is used in treatment of vegetative dysfunction in children and adolescents, especially associated with asthenical manifestations, as well as in complex therapy of exertion headache and migraine. The drug is effective in treatment of cognitive disorders in children and adolescents with epilepsy, pyritinol was administered without changing of the basic anticonvulsive therapy and no deterioration (increase of severity of seizures or intensity of epileptiform activity on electroencephalogramms was observed. Significant nootropic effect of pyritinol, including neurometabolic, neuroprotective, neurodynamic and other mechanisms, in association with safety and rare side effects of this drug determines its wide usage in pediatric neurology.

  10. Muscular anatomy of the Podocoryna carnea hydrorhiza. (United States)

    Buss, Leo W; Anderson, Christopher; Bolton, Edward W


    The muscular anatomy of the athecate hydroid Podocoryna carnea hydrorhiza is elucidated. The polyp-stolon junction is characterized by an opening, here called the chloe, in the otherwise continuous hydrorhizal perisarc. The chloe is elliptical when the polyp first arises, but takes on a more complex outline as multiple stolons anastomose to communicate with that polyp. Surrounding the polyp base are spots, here called anchors, which autofluoresce at the same wavelengths as perisarc and which, like perisarc, contain chitin as assessed by Calcofluor White, Congo Red and wheat germ agglutinin staining. Anchors remain after living tissues are digested using KOH. Collagen IV staining indicates that the mesoglea is pegged to the anchors and rhodamine phallodin staining detects cytoskeletal F-actin fibers of the basal epidermis surrounding the anchors. Longitudinal muscle fibers of the polyp broaden at the polyp base and are inserted into the mesoglea of the underlying stolon, but were neither observed to extend along the stolonal axis nor to attach to the anchors. Circular muscular fibers of the polyp extend into stolons as a dense collection of strands running along the proximal-distal axis of the stolon. These gastrodermal axial muscular fibers extend to the stolon tip. Epidermal cells at the stolon tip and the polyp bud display a regular apical latticework of F-actin staining. A similar meshwork of F-actin staining was found in the extreme basal epidermis of all stolons. Immunohistochemical staining for tubulin revealed nerves at stolon tips, but at no other hydrorhizal locations. These studies bear on the mechanisms by which the stolon tip and polyp bud pulsate, the manner in which the stolon lumen closes, and on the developmental origin of the basal epidermis of the hydrorhiza.

  11. Child Neurology Education for Pediatric Residents. (United States)

    Albert, Dara V F; Patel, Anup D; Behnam-Terneus, Maria; Sautu, Beatriz Cunill-De; Verbeck, Nicole; McQueen, Alisa; Fromme, H Barrett; Mahan, John D


    The aim of this study was to evaluate whether the current state of child neurology education during pediatric residency provides adequate preparation for pediatric practice. A survey was sent to recent graduates from 3 pediatric residency programs to assess graduate experience, perceived level of competence, and desire for further education in child neurology. Responses from generalists versus subspecialists were compared. The response rate was 32%, half in general pediatric practice. Only 22% feel very confident in approaching patients with neurologic problems. This may represent the best-case scenario as graduates from these programs had required neurology experiences, whereas review of Accreditation Council of Graduate Medical Education-accredited residency curricula revealed that the majority of residencies do not. Pediatric neurologic problems are common, and pediatric residency graduates do encounter such problems in practice. The majority of pediatricians report some degree of confidence; however, some clear areas for improvement are apparent.

  15. [Clinical points for progressive muscular dystrophy - is immobobilization the only concern?]. (United States)

    Komaki, Hirofumi


    Progressive muscular dystrophy presents with various complications as the disease progresses, besides decreased motor function. It is critical to make an appropriate and accurate diagnosis and to provide appropriate multidisciplinary medical care continuously from the time of diagnosis, including pharmacotherapy, rehabilitation, orthopedic treatment, respiratory/cardiovascular care, nutritional support and psycho-social care. This will contribute significantly not only to the survival prognosis, but also to improvement of the quality of life of these patients. A comprehensive and proactive posture (result-oriented assessment and coping) toward those therapeutic approaches is important in clinical practice. This concept is common to other rare diseases and neurological intractable diseases and may be applicable to these diseases.

    Sejerson, Thomas; Bushby, Kate


    Care for patients with Duchenne muscular dystrophy (DMD) is poorly standardised. There are many interventions in different systems which are known to improve outcomes in DMD but these are not uniformly applied. This leads to inequality in access to treatment, as well as problems for planning controlled trials of future therapeutics. A worldwide effort is underway to generate care guidelines for DMD, which involves the Centre for Disease Control in the USA and the TREAT-NMD network of excellence for neuromuscular diseases in Europe. In advance of the full consensus document, TREAT-NMD has worked on the generation of brief standards of care for DMD, which are presented here and are available via the TREAT-NMD website ( Guidelines are presented for diagnostics, neurological follow up, gastrointestinal and nutritional issues, respiratory and cardiac care as well as orthopaedics, rehabilitation, psychosocial interventions and oral care.

    Full Text Available OBJECTIVE: To study tremor in patients with X-linked recessive spinobulbar muscular atrophy or Kennedy's disease. METHODS: Ten patients (from 7 families with a genetic diagnosis of Kennedy's disease were screened for the presence of tremor using a standardized clinical protocol and followed up at a neurology outpatient clinic. All index patients were genotyped and showed an expanded allele in the androgen receptor gene. RESULTS: Mean patient age was 37.6 years and mean number of CAG repeats 47 (44-53. Tremor was present in 8 (80% patients and was predominantly postural hand tremor. Alcohol responsiveness was detected in 7 (88% patients with tremor, who all responded well to treatment with a β-blocker (propranolol. CONCLUSION: Tremor is a common feature in patients with Kennedy's disease and has characteristics similar to those of essential tremor.

    Hara, Kenju; Tateyama, Maki; Suzuki, Naoki; Shibano, Ken; Tanaka, Keiko; Ishiguro, Hideaki


    A 60-year-old woman was admitted to our hospital because of difficulty in standing on her toes. Neurological examination showed muscle weakness in both calf muscles. Her serum creatine kinase (CK) level was slightly elevated. MRI revealed hyper-intense signals localized in both the gastrocnemius and soleus muscles. Histological examinations of biopsied muscle specimens showed a marked variation in fiber size, small angular fibers, and hypertrophic and splitting fibers, but no muscle fiber necrosis or regeneration or inflammatory cell infiltration. ATPase stained sections showed small grouped atrophy of type 1 fibers. NADH-TR stained sections showed target/targetoid fibers predominantly in type 1 fibers. Dysferlin immunoreactivity was normal. Follow-up clinical evaluation for one year showed no progression. This patient was diagnosed as having an unknown type of spinal muscular atrophy or benign calf amyotrophy. Sporadic cases characterized by elderly-onset, neurogenic muscular atrophy localized in both calf muscles, and non-progressive course are extremely rare in Japan.

  19. Relationships between lower limb and trunk discomfort and vascular, muscular and kinetic outcomes during stationary standing work. (United States)

    Antle, David M; Côté, Julie N


    Standing work is associated with discomfort and symptoms in the trunk and lower limb. However, mechanisms underlying these observations are poorly understood. Moreover, most research on standing-related symptoms has focused on only one region (lower limb or trunk), and has not considered the impact and interactions between vascular, muscular and balance outcomes. We measured foot and soleus blood flow, ankle mean arterial pressure, muscle activity of the plantar and dorsi flexors, gluteus medius and trunk flexors and extensors, center of pressure changes and leg and back discomfort in 18 healthy volunteers performing a repetitive box-folding task for 34 min. Results show significant decreases with time in lower limb muscle activity (plower limb (porigin of standing-related lower limb discomfort is likely vascular in origin, whereas back discomfort is likely multifactorial, involving muscular, vascular and postural control variables.

    Schwarz, Heidi B; Fritz, Joseph V; Govindarajan, Raghav; Penfold Murray, Rebecca; Boyle, Kathryn B; Getchius, Thomas S D; Freimer, Miriam


    There are many factors driving health care reform, including unsustainable costs, poor outcomes, an aging populace, and physician shortages. These issues are particularly relevant to neurology. New reimbursement models are based on value and facilitated by the use of multidisciplinary teams. Integration of advanced practice providers (APPs) into neurology practice offers many advantages with new models of care. Conversely, there are many and varied challenges financially and logistically with these practice models. The American Academy of Neurology has formed a Work Group to address the needs of both neurologists and neurologic APPs and monitor the effect of APPs on quality and cost of neurologic care.

  1. Neurology in the Vietnam War. (United States)

    Gunderson, Carl H; Daroff, Robert B


    Between December 1965 and December 1971, the United States maintained armed forces in Vietnam never less than 180,000 men and women in support of the war. At one time, this commitment exceeded half a million soldiers, sailors, and airmen from both the United States and its allies. Such forces required an extensive medical presence, including 19 neurologists. All but two of the neurologists had been drafted for a 2-year tour of duty after deferment for residency training. They were assigned to Vietnam for one of those 2 years in two Army Medical Units and one Air Force facility providing neurological care for American and allied forces, as well as many civilians. Their practice included exposure to unfamiliar disorders including cerebral malaria, Japanese B encephalitis, sleep deprivation seizures, and toxic encephalitis caused by injection or inhalation of C-4 explosive. They and neurologists at facilities in the United States published studies on all of these entities both during and after the war. These publications spawned the Defense and Veterans Head Injury Study, which was conceived during the Korean War and continues today as the Defense and Veterans Head Injury Center. It initially focused on post-traumatic epilepsy and later on all effects of brain injury. The Agent Orange controversy arose after the war; during the war, it was not perceived as a threat by medical personnel. Although soldiers in previous wars had developed serious psychological impairments, post-traumatic stress disorder was formally recognized in the servicemen returning from Vietnam. © 2016 S.

  2. Consensus on the diagnosis, treatment and follow-up of patients with Duchenne muscular dystrophy. (United States)

    Nascimento Osorio, A; Medina Cantillo, J; Camacho Salas, A; Madruga Garrido, M; Vilchez Padilla, J J


    Duchenne muscular dystrophy (DMD) is the most common myopathy in children, with a worldwide prevalence of approximately 0.5 cases per 10,000 male births. It is characterised by a progressive muscular weakness manifesting in early childhood, with the subsequent appearance of musculoskeletal, respiratory, and cardiac complications, causing disability, dependence, and premature death. Currently, DMD is mainly managed with multidisciplinary symptomatic treatment, with favourable results in terms of the progression of the disease. It is therefore crucial to establish clear, up-to-date guidelines enabling early detection, appropriate treatment, and monitoring of possible complications. We performed a literature search of the main biomedical databases for articles published in the last 10years in order to obtain an overview of the issues addressed by current guidelines and to identify relevant issues for which no consensus has yet been established. The degree of evidence and level of recommendation of the information obtained were classified and ordered according to the criteria of the American Academy of Neurology. DMD management should be multidisciplinary and adapted to the patient's profile and the stage of clinical progression. In addition to corticotherapy, treatment targeting gastrointestinal, respiratory, cardiac, and orthopaedic problems, as well as physiotherapy, should be provided with a view to improving patients' quality of life. Genetic studies play a key role in the management of the disease, both in detecting cases and potential carriers and in characterising the mutation involved and developing new therapies.

    To determine if magnetic resonance imaging (MR imaging) is useful in the diagnostic workup of muscular dystrophies and idiopathic inflammatory myopathies for describing the topography of muscle involvement. MR imaging was performed in 31 patients: 8 with dystrophic myotony types 1 (n = 4) or 2 (n = 4); 11 with limb-girdle muscular dystrophy, including dysferlinopathy, calpainopathy, sarcoglycanopathy, and dystrophy associated with fukutin-related protein mutation; 3 with Becker muscular dystrophy; and 9 with idiopathic inflammatory myopathies, including polymyositis, dermatomyositis, and sporadic inclusion body myositis. Analysis of T1 images enabled us to describe the most affected muscles and the muscles usually spared for each muscular disease. In particular, examination of pelvis, thigh, and leg muscles demonstrated significant differences between the muscular diseases. On STIR images, hyperintensities were present in 62% of our patients with muscular dystrophies. A specific pattern of muscular involvement was established for each muscular disease. Hyperintensities observed on STIR images precede fatty degeneration and are not specific for inflammatory myopathies. (orig.)

  8. Upper girdle imaging in facioscapulohumeral muscular dystrophy.

    Directory of Open Access Journals (Sweden)

    Giorgio Tasca

    Full Text Available In Facioscapulohumeral muscular dystrophy (FSHD, the upper girdle is early involved and often difficult to assess only relying on physical examination. Our aim was to evaluate the pattern and degree of involvement of upper girdle muscles in FSHD compared with other muscle diseases with scapular girdle impairment.We propose an MRI protocol evaluating neck and upper girdle muscles. One hundred-eight consecutive symptomatic FSHD patients and 45 patients affected by muscular dystrophies and myopathies with prominent upper girdle involvement underwent this protocol. Acquired scans were retrospectively analyzed.The trapezius (100% of the patients and serratus anterior (85% of the patients were the most and earliest affected muscles in FSHD, followed by the latissimus dorsi and pectoralis major, whilst spinati and subscapularis (involved in less than 4% of the patients were consistently spared even in late disease stages. Asymmetry and hyperintensities on short-tau inversion recovery (STIR sequences were common features, and STIR hyperintensities could also be found in muscles not showing signs of fatty replacement. The overall involvement appears to be disease-specific in FSHD as it significantly differed from that encountered in the other myopathies.The detailed knowledge of single muscle involvement provides useful information for correctly evaluating patients' motor function and to set a baseline for natural history studies. Upper girdle imaging can also be used as an additional tool helpful in supporting the diagnosis of FSHD in unclear situations, and may contribute with hints on the currently largely unknown molecular pathogenesis of this disease.

  9. The influence of muscular lengthening on cramps. (United States)

    Bertolasi, L; De Grandis, D; Bongiovanni, L G; Zanette, G P; Gasperini, M


    Muscle cramps induced by voluntary contraction and by electrical stimulation of the peripheral nerve were studied electrophysiologically in 10 healthy subjects. The aim was to verify that cramps can be evoked by electrical stimulation of peripheral nerve and to clarify the physiological mechanism responsible by analyzing the effect of muscular stretching on cramps. Our results showed: (1) Cramps can be induced even after peripheral nerve block by electrical stimulation distal to the block. (2) No cramps were recorded during or following maximal voluntary contraction without muscular shortening, while 7 of 10 subjects showed a true cramp following maximal effort with shortening of the muscle. (3) Muscle stretching caused a sudden interruption of cramps induced by either voluntary contraction or electrical stimulation of the peripheral nerve, even after the induction of nerve block. (4) The lengthening state of the muscle can strongly influence the possibility of evoking cramps by electrical stimulation of nerve. Our study verifies the experimental model proposed by Lambert in 1969, emphasizing the relevance of frequency of stimulation and confirming the hypothesis that cramps are of peripheral origin. The effects of muscle stretch and lengthening on cramp interruption and development also have a peripheral mechanism.

  10. Muscle MRI findings in facioscapulohumeral muscular dystrophy

    Gerevini, Simonetta; Caliendo, Giandomenico; Falini, Andrea [IRCCS San Raffaele Scientific Institute, Neuroradiology Unit, Head and Neck Department, Milan (Italy); Scarlato, Marina; Previtali, Stefano Carlo [IRCCS San Raffaele Scientific Institute, Department of Neurology, INSPE and Division of Neuroscience, Milan (Italy); Maggi, Lorenzo; Pasanisi, Barbara; Morandi, Lucia [Fondazione IRCCS Istituto Neurologico ' ' Carlo Besta' ' , Neuromuscular Diseases and Neuroimmunology Unit, Milan (Italy); Cava, Mariangela [IRCCS San Raffaele Scientific Institute, Department of Radiology and Center for Experimental Imaging, Milan (Italy)


    Facioscapulohumeral muscular dystrophy (FSHD) is characterized by extremely variable degrees of facial, scapular and lower limb muscle involvement. Clinical and genetic determination can be difficult, as molecular analysis is not always definitive, and other similar muscle disorders may have overlapping clinical manifestations. Whole-body muscle MRI examination for fat infiltration, atrophy and oedema was performed to identify specific patterns of muscle involvement in FSHD patients (30 subjects), and compared to a group of control patients (23) affected by other myopathies (NFSHD). In FSHD patients, we detected a specific pattern of muscle fatty replacement and atrophy, particularly in upper girdle muscles. The most frequently affected muscles, including paucisymptomatic and severely affected FSHD patients, were trapezius, teres major and serratus anterior. Moreover, asymmetric muscle involvement was significantly higher in FSHD as compared to NFSHD patients. In conclusion, muscle MRI is very sensitive for identifying a specific pattern of involvement in FSHD patients and in detecting selective muscle involvement of non-clinically testable muscles. Muscle MRI constitutes a reliable tool for differentiating FSHD from other muscular dystrophies to direct diagnostic molecular analysis, as well as to investigate FSHD natural history and follow-up of the disease.

  11. Congenital muscular dystrophy with inflammation: Diagnostic considerations

    Directory of Open Access Journals (Sweden)

    Kaumudi Konkay


    Full Text Available Background and Purpose: Muscle biopsy features of congenital muscular dystrophies (CMD vary from usual dystrophic picture to normal or nonspecific myopathic picture or prominent fibrosis or striking inflammatory infiltrate, which may lead to diagnostic errors. A series of patients of CMD with significant inflammatory infiltrates on muscle biopsy were correlated with laminin α 2 deficiency on immunohistochemistry (IHC. Material and Methods: Cryostat sections of muscle biopsies from the patients diagnosed as CMD on clinical and muscle biopsy features from 1996 to 2014 were reviewed with hematoxylin and eosin(H&E, enzyme and immunohistochemistry (IHC with laminin α 2. Muscle biopsies with inflammatory infiltrate were correlated with laminin α 2 deficiency. Results: There were 65 patients of CMD, with inflammation on muscle biopsy in 16. IHC with laminin α 2 was available in nine patients, of which six showed complete absence along sarcolemma (five presented with floppy infant syndrome and one with delayed motor milestones and three showed discontinuous, and less intense staining. Conclusions: CMD show variable degrees of inflammation on muscle biopsy. A diagnosis of laminin α 2 deficient CMD should be considered in patients of muscular dystrophy with inflammation, in children with hypotonia/delayed motor milestones.

  12. Emerging drugs for Duchenne muscular dystrophy. (United States)

    Malik, Vinod; Rodino-Klapac, Louise R; Mendell, Jerry R


    Duchenne muscular dystrophy (DMD) is the most common, severe childhood form of muscular dystrophy. Treatment is limited to glucocorticoids that have the benefit of prolonging ambulation by approximately 2 years and preventing scoliosis. Finding a more satisfactory treatment should focus on maintaining long-term efficacy with a minimal side effect profile. Authors discuss different therapeutic strategies that have been used in pre-clinical and clinical settings. Multiple treatment approaches have emerged. Most attractive are molecular-based therapies that can express the missing dystrophin protein (exon skipping or mutation suppression) or a surrogate gene product (utrophin). Other approaches include increasing the strength of muscles (myostatin inhibitors), reducing muscle fibrosis and decreasing oxidative stress. Additional targets include inhibiting NF-κB to reduce inflammation or promoting skeletal muscle blood flow and muscle contractility using phosphodiesterase inhibitors or nitric oxide (NO) donors. The potential for each of these treatment strategies to enter clinical trials is a central theme of discussion. The review emphasizes that the goal of treatment should be to find a product at least as good as glucocorticoids with a lower side effect profile or with a significant glucocorticoid sparing effect.

  13. Cervical Spine Dysmorphism in Congenital Muscular Torticollis. (United States)

    Hussein, Mohammed Ahmed; Yun, In Sik; Lee, Dong Won; Park, Hanna; Oock, Kim Yong


    Congenital muscular torticollis is a common childhood musculoskeletal anomaly that might result in permanent craniofacial deformity, facial asymmetry, and changes in the cervical vertebrae, if not treated during early childhood. Although there have been many studies on cervical vertebral changes, their onset in children has not been previously studied. Fifteen patients (aged axis across the midsagittal plane was done to compare the anatomical changes. The volumes of each halves of the atlas and axis were measured. An apparent change was observed in the axis of the vertebral column when compared with that of the skull. There were progressive anatomical changes affecting the upper cervical vertebrae, which started to develop around the age of 8 months and became more evident in older children. The axis vertebra was the first to be affected. Rotational and bending deformities were the most likely changes to occur. Pearson correlation analysis showed a statistically significant trend in the volume and height changes for both halves of the atlas and axis (P < 0.001 and P < 0.001). Children with untreated congenital muscular torticollis show progressive anatomical changes of the cervical vertebrae which started at the age of 8 months. The severity of the deformity increased with the advance of age as well as with the severity of sternocleidomastoid tightness, which might result in permanent deformities.

  14. The superhealing MRL background improves muscular dystrophy

    Heydemann Ahlke


    Full Text Available Abstract Background Mice from the MRL or “superhealing” strain have enhanced repair after acute injury to the skin, cornea, and heart. We now tested an admixture of the MRL genome and found that it altered the course of muscle pathology and cardiac function in a chronic disease model of skeletal and cardiac muscle. Mice lacking γ-sarcoglycan (Sgcg, a dystrophin-associated protein, develop muscular dystrophy and cardiomyopathy similar to their human counterparts with limb girdle muscular dystrophy. With disruption of the dystrophin complex, the muscle plasma membrane becomes leaky and muscles develop increased fibrosis. Methods MRL/MpJ mice were bred with Sgcg mice, and cardiac function was measured. Muscles were assessed for fibrosis and membrane leak using measurements of hydroxyproline and Evans blue dye. Quantitative trait locus mapping was conducted using single nucleotide polymorphisms distinct between the two parental strains. Results Introduction of the MRL genome reduced fibrosis but did not alter membrane leak in skeletal muscle of the Sgcg model. The MRL genome was also associated with improved cardiac function with reversal of depressed fractional shortening and the left ventricular ejection fraction. We conducted a genome-wide analysis of genetic modifiers and found that a region on chromosome 2 was associated with cardiac, diaphragm muscle and abdominal muscle fibrosis. Conclusions These data are consistent with a model where the MRL genome acts in a dominant manner to suppress fibrosis in this chronic disease setting of heart and muscle disease.

  15. Severe neurological complication following adjustable gastric banding. (United States)

    Martines, G; Musa, N; Aquilino, F; Capuano, P


    In the last years with the increase of bariatric surgery, first of all as a result of new indications, a rise in the incidence of nutrient-related complications has been observed. Currently little is known about the impact of post-bariatric malnutrition and neurological complications. Wernicke's encephalopathy is a severe neurological syndrome which occurs as a result of thiamine deficiency. Wernicke-Korsakoff syndrome must be considered a serious neurological complication of bariatric surgery with significant morbidity and mortality, with rapidly progressing neurological symptoms, and must be treated immediately. We report the case of a 35 years-old male patient, affected by morbid obesity, anxious-depressive syndrome and alcohol use disorder, who after adjustable gastric banding implanted in another hospital developed a severe malnutrition and neurological syndrome. The patient showed poor adherence to the follow-up and to the dietary indications and after all, we needed to place a PEG for enteral nutrition in order to resolve the malnutrition condition and the neurological syndrome. Our experience emphasizes that preoperative selection and assessment of a patient's nutritional status according to guidelines, is required to identify potential problems, and that bariatric surgeons or physicians caring for patient who have undergone bariatric surgery should be familiar with the constellation of nutritional and neurological disorder that may occur after surgery. We want to remark the importance of preoperative selection of the patients, the follow-up and the cooperation between patient and physician in order to obtain the best result and avoid severe complications.

  16. Neurocritical care education during neurology residency (United States)

    Drogan, O.; Manno, E.; Geocadin, R.G.; Ziai, W.


    Objective: Limited information is available regarding the current state of neurocritical care education for neurology residents. The goal of our survey was to assess the need and current state of neurocritical care training for neurology residents. Methods: A survey instrument was developed and, with the support of the American Academy of Neurology, distributed to residency program directors of 132 accredited neurology programs in the United States in 2011. Results: A response rate of 74% (98 of 132) was achieved. A dedicated neuroscience intensive care unit (neuro-ICU) existed in 64%. Fifty-six percent of residency programs offer a dedicated rotation in the neuro-ICU, lasting 4 weeks on average. Where available, the neuro-ICU rotation was required in the vast majority (91%) of programs. Neurology residents' exposure to the fundamental principles of neurocritical care was obtained through a variety of mechanisms. Of program directors, 37% indicated that residents would be interested in performing away rotations in a neuro-ICU. From 2005 to 2010, the number of programs sending at least one resident into a neuro-ICU fellowship increased from 14% to 35%. Conclusions: Despite the expansion of neurocritical care, large proportions of US neurology residents have limited exposure to a neuro-ICU and neurointensivists. Formal training in the principles of neurocritical care may be highly variable. The results of this survey suggest a charge to address the variability of resident education and to develop standardized curricula in neurocritical care for neurology residents. PMID:22573636

  17. Chapter 44: history of neurology in Italy. (United States)

    Bentivoglio, Marina; Mazzarello, Paolo


    The chapter starts from the Renaissance (although the origins of Italian neurology can be traced back to the Middle Ages), when treatises of nervous system physiopathology still followed Hippocratic and Galenic "humoral" theories. In Italy, as elsewhere in Europe, the concepts of humoral pathology were abandoned in the 18th century, when neurology was influenced by novel trends. Neurology acquired the status of clinical discipline (as "clinic of mental diseases") after national reunification (declared in 1861 but completed much later). At the end of the 19th and first decades of the 20th century, eminent Italian "neuropsychiatrists" (including, among many others, Ugo Cerletti, who introduced electroconvulsive shock therapy in 1938) stimulated novel knowledge and approaches, "centers of excellence" flourished, and "Neurological Institutes" were founded. In the first half of the 20th century, the history of Italian neurology was dominated by World Wars I and II (which stimulated studies on the wounded) and the fascist regime in-between the Wars (when the flow of information was instead very limited). Italy became a republic in 1946, and modern neurology and its distinction from psychiatry were finally promoted. The chapter also provides detailed accounts of scientific societies and journals dedicated to the neurological sciences in Italy.

  18. Genetic modifiers of Duchenne and facioscapulohumeral muscular dystrophies. (United States)

    Hightower, Rylie M; Alexander, Matthew S


    Muscular dystrophy is defined as the progressive wasting of skeletal muscles that is caused by inherited or spontaneous genetic mutations. Next-generation sequencing has greatly improved the accuracy and speed of diagnosis for different types of muscular dystrophy. Advancements in depth of coverage, convenience, and overall reduced cost have led to the identification of genetic modifiers that are responsible for phenotypic variability in affected patients. These genetic modifiers have been postulated to explain key differences in disease phenotypes, including age of loss of ambulation, steroid responsiveness, and the presence or absence of cardiac defects in patients with the same form of muscular dystrophy. This review highlights recent findings on genetic modifiers of Duchenne and facioscapulohumeral muscular dystrophies based on animal and clinical studies. These genetic modifiers hold great promise to be developed into novel therapeutic targets for the treatment of muscular dystrophies. Muscle Nerve 57: 6-15, 2018. © 2017 Wiley Periodicals, Inc.

  2. Digital Footprint of Neurological Surgeons. (United States)

    Kim, Christopher; Gupta, Raghav; Shah, Aakash; Madill, Evan; Prabhu, Arpan V; Agarwal, Nitin


    Patients are increasingly turning to online resources to inquire about individual physicians and to gather health information. However, little research exists studying the online presence of neurosurgeons across the country. This study aimed to characterize these online profiles and assess the scope of neurosurgeons' digital identities. Medicare-participating neurologic surgeons from the United States and Puerto Rico were identified using the Centers for Medicare and Medicaid Services (CMS) Physician Comparable Downloadable File. Each physician was characterized by his or her medical education, graduation year, city of practice, gender, and affiliation with an academic institution. Using a Google-based custom search tool, the top 10 search results for each physician were extracted and categorized as 1 of the following: 1) physician, hospital, or healthcare system controlled, 2) third-party or government controlled, 3) social media-based, 4) primary journal article, or 5) other. Among the physicians within the CMS database, 4751 self-identified as being neurosurgeons, yielding a total of 45,875 uniform resource locator search results pertinent to these physicians. Of the 4751 neurosurgeons, 2317 (48.8%) and 2434 (51.2%) were classified as academic and nonacademic neurosurgeons, respectively. At least 1 search result was obtained for every physician. Hospital, healthcare system, or physician-controlled websites (18,206; 39.7%) and third-party websites (17,122; 37.3%) were the 2 most commonly observed domain types. Websites belonging to social media platforms accounted for 4843 (10.6%) search results, and websites belonging to peer-reviewed academic journals accounted for 1888 (4.1%) search results. The frequency with which a third-party domain appeared as the first search result was higher for nonacademic neurosurgeons than for academic neurosurgeons. In general, neurosurgeons lacked a controllable online presence within their first page of Google Search results

  5. Neurological manifestations of Ehlers-Danlos syndrome(s): A review (United States)

    Castori, Marco; C. Voermans, Nicol


    The term “Ehlers-Danlos syndrome” (EDS) groups together an increasing number of heritable connective tissue disorders mainly featuring joint hypermobility and related complications, dermal dysplasia with abnormal skin texture and repair, and variable range of the hollow organ and vascular dysfunctions. Although the nervous system is not considered a primary target of the underlying molecular defect, recently, increasing attention has been posed on neurological manifestations of EDSs, such as musculoskeletal pain, fatigue, headache, muscle weakness and paresthesias. Here, a comprehensive overview of neurological findings of these conditions is presented primarily intended for the clinical neurologist. Features are organized under various subheadings, including pain, fatigue, headache, stroke and cerebrovascular disease, brain and spine structural anomalies, epilepsy, muscular findings, neuropathy and developmental features. The emerging picture defines a wide spectrum of neurological manifestations that are unexpectedly common and potentially disabling. Their evaluation and correct interpretation by the clinical neurologist is crucial for avoiding superfluous investigations, wrong therapies, and inappropriate referral. A set of basic tools for patient’s recognition is offered for raising awareness among neurologists on this underdiagnosed group of hereditary disorders. PMID:25632331

    Full Text Available Lidocaine has been used for more than 50 years for spinal anesthesia and has a remarkable safety record. In 1993, a new adverse effect, transient neurologic toxicity was described in patients recovering from spinal anesthesia with lidocaine. Transient neurological symptoms have been defined as pain in the lower extremities (buttocks, thighs and legs after an uncomplicated spinal anesthesia and after an initial full recovery during the immediate postoperative period (less than 24 h. The incidence of transient neurological symptoms reported in prospective, randomized trials varies from 4% to 37%. The etiology of transient neurological symptoms remains unkonwn. Despite the transient nature of this syndrome, it has proven to be difficult to treat effectively. Drug or some interventional therapy may be necessary.

  9. Neurologic deficit after resection of the sacrum. (United States)

    Biagini, R; Ruggieri, P; Mercuri, M; Capanna, R; Briccoli, A; Perin, S; Orsini, U; Demitri, S; Arlecchini, S


    The authors describe neurologic deficit (sensory, motor, and sphincteral) resulting from sacrifice of the sacral nerve roots removed during resection of the sacrum. The anatomical and functional bases of sphincteral continence and the amount of neurologic deficit are discussed based on level of sacral resection. A large review of the literature on the subject is reported and discussed. The authors emphasize how the neurophysiological bases of sphincteral continence (rectum and bladder) and of sexual ability are still not well known, and how the literature reveals disagreement on the subject. A score system is proposed to evaluate neurologic deficit. The clinical model of neurologic deficit caused by resection of the sacrum may be extended to an evaluation of post-traumatic deficit.

  11. Relevant aspects of golden retriever muscular dystrophy for the study of Duchenne muscular dystrophy in humans

    Directory of Open Access Journals (Sweden)

    Julieta Rodini Engrácia de Moraes


    Full Text Available ABSTRACT: Golden Retriever muscular dystrophy (GRMD is the most representative model for studying Duchenne muscular dystrophy (DMD in humans, owing its phenotypic expression. DMD is a recessive disorder linked to the X chromosome in which the loss of dystrophin induces progressive weakness and degeneration of the skeletal and cardiac muscles, which lead to replacement by connective and adipose tissues. Onset of clinical signs occurs between 2 and 5 years of age, and many patients die from heart or respiratory failure. The main studies concerning dystrophic Golden Retrievers (DGR sought to elucidate the pathophysiology of the disease and its clinical implications to develop therapies and alternative treatments to improve the quality of life and increase longevity of DMD patients. This review presents an overview of relevant contributions of the DGR model for elucidating DMD in humans.

    Full Text Available Celiac disease may initially present as a neurological disorder. Alternatively, celiac disease may be complicated by neurological changes. With impaired nutrient absorption, different deficiency syndromes may occur and these may be manifested clinically with neurological changes. However, in patients with deficiency syndromes, extensive involvement of the small intestine with celiac disease is often evident. There are a number of reports of celiac disease associated with neuropathy, ataxia, dementia and seizure disorder. In these reports, there is no clear relationship with nutrient deficiency and a precise mechanism for the neurological changes has not been defined. A small number of patients have been reported to have responded to vitamin E administration, but most do not. In some, gluten antibodies have also been described, especially in those with ataxia, but a consistent response to a gluten-free diet has not been defined. Screening for celiac disease should be considered in patients with unexplained neurological disorders, including ataxia and dementia. Further studies are needed, however, to determine if a gluten-free diet will lead to improvement in the associated neurological disorder.

  17. Current treatment of adult Duchenne muscular dystrophy. (United States)

    Wagner, Kathryn R; Lechtzin, Noah; Judge, Daniel P


    Patients with Duchenne muscular dystrophy (DMD) are living longer into adulthood due to a variety of improvements in health care practices. This growing patient population presents new therapeutic challenges. In this article, we review the literature on current treatment of adult DMD as well as our own experience as a multidisciplinary team actively caring for 23 men ages 19-38 years of age. Approximately one quarter of our adult DMD patients have remained on moderate dose corticosteroids. Daily stretching exercises are recommended, particularly of the distal upper extremities. Cardiomyopathy is anticipated, detected, and treated early with afterload reduction. Oxygen saturation monitoring, noninvasive positive pressure ventilation and cough assist devices are routinely used. Other medical issues such as osteoporosis, gastrointestinal and urinary symptoms are addressed. Current and future therapies directed at prolonging the lifespan of those with DMD will result in further increases in this adult population with special needs and concerns. These needs are best addressed in a multidisciplinary clinic.

  18. Natural history of Duchenne muscular dystrophy

    Directory of Open Access Journals (Sweden)

    Qing KE


    Full Text Available Duchenne muscular dystrophy (DMD is X-linked recessive hereditary disease. DMD gene mutations result in dystrophin deficiency, which causes not only muscle movement disorders but also scoliosis, cognitive dysfunction, urinary tract diseases, respiratory diseases and heart diseases. Most patients die in early adult for respiratory and circulatory failure. Early multidisciplinary therapies will significantly delay disease progression and improve patients' quality of life. However, DMD diagnosis and treatment exist significantly time delay now. In this study, we review the natural history of DMD, including motor, cognitive, respiratory and heart function, for improving DMD early recognition, diagnosis and treatment, so as to benefit DMD patients. DOI: 10.3969/j.issn.1672-6731.2015.05.004

    Ionasescu, V.; Lara-Braud, C.; Zellweger, H.; Ionasescu, R.; Burmeister, L.


    Primary skin fibroblast cultures were grown from forearm pinch skin biopsies obtained from 24 patients with Duchenne muscular dystrophy (DMD) and ten normal controls matched for sex and age. The first subcultures were grown for 7 days and incubated with L-( 3 H)-proline for 24 hours. Intracellular collagen incoption was significantly decreased (2.2 X) and extracellular collagen incorporation significantly increased (1.8 X) in fibroblast cultures from patients with DMD by both collagenase assay and polyacrylamide gel electrophoresis. The synthesis of noncollagen proteins showed low values from the DMD fibroblast cultures. The alterations in synthesis and secretion of collagen and noncollagen proteins were characteristic only for the log phase of DMD fibroblasts. (author)

  20. The Importance of Muscular Strength: Training Considerations. (United States)

    Suchomel, Timothy J; Nimphius, Sophia; Bellon, Christopher R; Stone, Michael H


    This review covers underlying physiological characteristics and training considerations that may affect muscular strength including improving maximal force expression and time-limited force expression. Strength is underpinned by a combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition. Although single- and multi-targeted block periodization models may produce the greatest strength-power benefits, concepts within each model must be considered within the limitations of the sport, athletes, and schedules. Bilateral training, eccentric training and accentuated eccentric loading, and variable resistance training may produce the greatest comprehensive strength adaptations. Bodyweight exercise, isolation exercises, plyometric exercise, unilateral exercise, and kettlebell training may be limited in their potential to improve maximal strength but are still relevant to strength development by challenging time-limited force expression and differentially challenging motor demands. Training to failure may not be necessary to improve maximum muscular strength and is likely not necessary for maximum gains in strength. Indeed, programming that combines heavy and light loads may improve strength and underpin other strength-power characteristics. Multiple sets appear to produce superior training benefits compared to single sets; however, an athlete's training status and the dose-response relationship must be considered. While 2- to 5-min interset rest intervals may produce the greatest strength-power benefits, rest interval length may vary based an athlete's training age, fiber type, and genetics. Weaker athletes should focus on developing strength before emphasizing power-type training. Stronger athletes may begin to emphasize power-type training while maintaining/improving their strength. Future research should

  1. Skeletal muscle homeostasis in Duchenne muscular dystrophy: modulating autophagy as a promising therapeutic strategy

    Directory of Open Access Journals (Sweden)

    Clara eDe Palma


    Full Text Available Muscular dystrophies are a group of genetic and heterogeneous neuromuscular disorders characterised by the primary wasting of skeletal muscle. In Duchenne muscular dystrophy (DMD, the most severe form of these diseases, the mutations in the dystrophin gene lead to muscle weakness and wasting, exhaustion of muscular regenerative capacity and chronic local inflammation leading to substitution of myofibres by connective and adipose tissue. DMD patients suffer of continuous and progressive skeletal muscle damage followed by complete paralysis and death, usually by respiratory and/or cardiac failure. No cure is yet available, but several therapeutic approaches aiming at reversing the ongoing degeneration have been investigated in preclinical and clinical settings. The autophagy is an important proteolytic system of the cell and has a crucial role in the removal of proteins, aggregates and organelles. Autophagy is constantly active in skeletal muscle and its role in tissue homeostasis is complex: at high levels it can be detrimental and contribute to muscle wasting; at low levels it can cause weakness and muscle degeneration, due to the unchecked accumulation of damaged proteins and organelles. The causal relationship between DMD pathogenesis and dysfunctional autophagy has been recently investigated. At molecular levels, the Akt axis is one of the key disregulated pathways, although the molecular events are not completely understood.The aim of this review is to describe and discuss the clinical relevance of the recent advances dissecting autophagy and its signalling pathway in DMD. The picture might pave the way for the development of interventions that are able to boost muscle growth and/or prevent muscle wasting.

  3. How flares can be understood

    International Nuclear Information System (INIS)

    Severny, A.B.


    Specific features of the flare phenomenon which are important for understanding of flares are the following: (1) Fine structure of visible emission of flares, especially at the very beginning and in the pre-flare active region. This structure can be seen also in later stages of development as bright points, some of which exist from the flare beginning (Babin's observations at Crimea, 1972-1976). (2) Turbulent motion with velocities up to 250-300 km s -1 as can be estimated from broadening of emission lines. (3) Predominantly red asymmetry of emission lines in the explosive phase and during further development of flares. (4) 'Supersonic' velocities and supergravitational accelerations of separate moving masses of the flare plasma. (5) The appearance of flares in areas with high grad H, exceeding 0.1 G km -1 which is equivalent to regions of electric currents > approximately 10 11 A. (6) Strong variations of net magnetic flux through the active region, as it follows from Meudon, Crimean, and Sacramento Peak (Rust's) observations. (Auth.)

    The World Congress of Neurology (figure 1) theme "Neurology in a Globalizing World" acknowledges that science and increasingly medicine and neurology are becoming globalized. The best way to manage change is to shape it. It is becoming increasingly clear that brain diseases, particularly stroke and dementia, are projected to rise at a rate that could overwhelm our clinics and hospitals. Hence a new emphasis on prevention and the need to work across disciplines beyond our traditional roles. Neurologists are the guardians of the brain and need to take the lead role in advancing new approaches in stemming the tide of neurologic diseases.

  8. Genetics and emerging treatments for Duchenne and Becker muscular dystrophy. (United States)

    Wein, Nicolas; Alfano, Lindsay; Flanigan, Kevin M


    Mutations in the DMD gene result in Duchenne or Becker muscular dystrophy due to absent or altered expression of the dystrophin protein. The more severe Duchenne muscular dystrophy typically presents around ages 2 to 5 with gait disturbance, and historically has led to the loss of ambulation by age 12. It is important for the practicing pediatrician, however, to be aware of other presenting signs, such as delayed motor or cognitive milestones, or elevated serum transaminases. Becker muscular dystrophy is milder, often presenting after age 5, with ambulation frequently preserved past 20 years and sometimes into late decades. Copyright © 2015 Elsevier Inc.

    We analyzed the microcomponents of protein fractions in the cerebrospinal fluid of patients with various types of muscular dystrophy. The degenerative pattern is characterized by an increase in the prealbumin and a decrease in the γ-globulin fraction is shown in the Duchenne and congenital muscular dystrophy. The increase in CSF IgG, γ-globulin fraction is shown in the myotonic dystrophy. In addition to the abnormality of IQ, EEG, and brain CT, abnormal CSF proteins obviously suggest the presence of CNS involvement in muscular dystrophy. (author)

  10. Electrical impedance myography for assessment of Duchenne muscular dystrophy. (United States)

    Sensitive, objective, and easily applied methods for evaluating disease progression and response to therapy are needed for clinical trials in Duchenne muscular dystrophy (DMD). In this study, we evaluated whether electrical impedance myography (EIM) could serve this purpose. In this nonblinded study, 36 boys with DMD and 29 age-similar healthy boys underwent multifrequency EIM measurements for up to 2 years on 6 muscles unilaterally along with functional assessments. A linear mixed-effects model with random intercept and slope terms was used for the analysis of multifrequency EIM values and functional measures. Seven DMD boys were initiated on corticosteroids; these data were analyzed using a piecewise linear mixed-effects model. In boys > 7.0 years old, a significant difference in the slope of EIM phase ratio trajectories in the upper extremity was observed by 6 months of -0.074/month, p = 0.023, 95% confidence interval (CI) = -0.013, -0.14; at 2 years, this difference was -0.048/month, p < 0.0001, 95% CI = -0.028, -0.068. In boys ≤ 7.0 years old, differences appeared at 6 months in gastrocnemius (EIM phase slope = -0.83 °/kHz/mo, p = 0.007, 95% CI = -0.26, -1.40). EIM outcomes showed significant differences earlier than functional tests. Initiation of corticosteroids significantly improved the slope of EIM phase ratio (0.057/mo, p = 0.00019, 95% CI = 0.028, 0.086) and EIM phase slope (0.14 °/kHz/mo, p = 0.013, 95% CI = 0.028, 0.25), consistent with corticosteroids' known clinical benefit. EIM detects deterioration in muscles of both younger and older boys by 6 months; it also identifies the therapeutic effect of corticosteroid initiation. Because EIM is rapid to apply, painless, and requires minimal operator training, the technique deserves to be further evaluated as a biomarker in DMD clinical therapeutic trials.

  11. Status of neurology medical school education (United States)

    Ali, Imran I.; Isaacson, Richard S.; Safdieh, Joseph E.; Finney, Glen R.; Sowell, Michael K.; Sam, Maria C.; Anderson, Heather S.; Shin, Robert K.; Kraakevik, Jeff A.; Coleman, Mary; Drogan, Oksana


    Objective: To survey all US medical school clerkship directors (CDs) in neurology and to compare results from a similar survey in 2005. Methods: A survey was developed by a work group of the American Academy of Neurology Undergraduate Education Subcommittee, and sent to all neurology CDs listed in the American Academy of Neurology database. Comparisons were made to a similar 2005 survey. Results: Survey response rate was 73%. Neurology was required in 93% of responding schools. Duration of clerkships was 4 weeks in 74% and 3 weeks in 11%. Clerkships were taken in the third year in 56%, third or fourth year in 19%, and fourth year in 12%. Clerkship duration in 2012 was slightly shorter than in 2005 (fewer clerkships of ≥4 weeks, p = 0.125), but more clerkships have moved into the third year (fewer neurology clerkships during the fourth year, p = 0.051). Simulation training in lumbar punctures was available at 44% of schools, but only 2% of students attempted lumbar punctures on patients. CDs averaged 20% protected time, but reported that they needed at least 32%. Secretarial full-time equivalent was 0.50 or less in 71% of clerkships. Eighty-five percent of CDs were “very satisfied” or “somewhat satisfied,” but more than half experienced “burnout” and 35% had considered relinquishing their role. Conclusion: Trends in neurology undergraduate education since 2005 include shorter clerkships, migration into the third year, and increasing use of technology. CDs are generally satisfied, but report stressors, including inadequate protected time and departmental support. PMID:25305155

    Full Text Available Jean-Martin Charcot was a pioneer in a variety of subjects, including nervous system diseases; anatomy; physiology; pathology; and diseases of ageing, joints, and lungs. His medical achievements were mainly based on his anatomopathological proficiency, his observation, and his personal thoroughness that favored the delineation of the nosology of the main neurological diseases, including multiple sclerosis, amyotrophic lateral sclerosis, Parkinson’s disease, peroneal muscular atrophy, and hysteria/epilepsy. The link of this anatomoclinical method with iconographic representations and theatrical lessons, and the rich bibliographical documentations, carried out in a crowded diseased people barn - Salpetrière hospital were the basis of his achievements, which are still discussed 120 years after his death.

    Pescador Caroline Argenta


    Full Text Available A two-month-old lamb showing signs of severe neurological disease characterized by muscular tremors, hypermetria, and motor incoordination was submitted to the Veterinary Pathology Laboratory - Universidade Federal do Rio Grande do Sul, Brazil. At necropsy, the major findings were a marked reduction of the size of the cerebellum and bilateral dilatation of the lateral ventricles. Microscopically, areas of cellular disorganization in the cerebellar cortex, reduction of the granular layer of cerebellum associated with decreased density of cells, and the presence of large cytoplasmic vacuoles in the molecular layer were observed. Neurons of the gray matter of the brain and macrophages of the mesenteric lymph nodes stained positively by the immunohistochemistry test using the monoclonal antibody 15C5 against Bovine Viral Diarrhea Virus. Taken together, those results are consistent with a pestivirus infection, either Border Disease Virus (BDV or BVDV.

  14. Identification of a novel frameshift mutation in the DMD gene as the cause of muscular dystrophy in a Norfolk terrier dog. (United States)

    Jenkins, Christopher A; Forman, Oliver P


    A Norfolk terrier was referred to the Animal Health Trust neurology department with suspected dystrophin-deficient muscular dystrophy (DD-MD), which was confirmed by clinical workup and immunohistochemistry. Exon resequencing of the canine Duchenne Muscular Dystrophy (DMD) gene was undertaken to screen for potential disease causing mutations. The sequence data generated from all coding DMD exons revealed a 1 bp deletion in exon 22, causing a frameshift and premature termination of the coding sequence. Gene expression analysis indicated reduced levels of dystrophin transcript in the DD-MD case and western blot confirmed the absence of full length protein. The finding represents a novel mutation causing DD-MD in the dog.

    Lee, Shu-Li; Chou, Fan-Hao; Chin, Chi-Chun


    The role of "mother" is understood and represented differently by people from different cultures. In traditional Taiwanese society, mothers demonstrate their existence value by giving birth to and raising sons able to continue her husband's familial line. Sons bear the patriarchal name and care for their parents in old age. However, a son stricken, paralyzed and eventually killed by Duchenne muscular dystrophy (DMD) can destroy a mother's perceived value in this traditional social context. Mothers are thus soundless sufferers. Nurses have a critical role to play in giving encouragement and hope to mothers of children with DMD. Through their own difficult situation, these mothers can also highlight the value and importance of Taiwan's nurses, who work in conditions marked by overloading, high stress, and under-appreciation. Caring for women in critical need of empathy and support help nurses realize their own positive capacity to empower sufferers.

  16. Dystrophin Dp116: A yet to Be Investigated Product of the Duchenne Muscular Dystrophy Gene

    Directory of Open Access Journals (Sweden)

    Masafumi Matsuo


    Full Text Available The Duchenne muscular dystrophy (DMD gene is one of the largest genes in the human genome. The gene exhibits a complex arrangement of seven alternative promoters, which drive the expression of three full length and four shorter isoforms. Dp116, the second smallest product of the DMD gene, is a Schwann cell-specific isoform encoded by a transcript corresponding to DMD exons 56–79, starting from a promoter/exon S1 within intron 55. The physiological roles of Dp116 are poorly understood, because of its extensive homology with other isoforms and its expression in specific tissues. This review summarizes studies on Dp116, focusing on clinical findings and alternative activation of the upstream translation initiation codon that is predicted to produce Dp118.

    Michael P. Barnes


    Full Text Available The European Federation of Neurological Societies (EFNS Scientific Panel on Neurorehabilitation established a Task Force on standards in neurological rehabilitation in June 1996. The remit for the Task Force was to: (1 produce a report on the state of neurological rehabilitation across Europe; and (2 recommend standards for the provision of neurological services for disabled people. The main conclusions of the Task Force were as follows: (1 A questionnaire circulated to each European member country has indicated a significant lack of adequate neurological rehabilitation facilities across Europe. Very few countries have any established network of neurological rehabilitation centres. Few countries have adequately trained neurological rehabilitation physicians, therapists or nurses. Such poor facilities should be seen in the context of the large numbers and increasing prevalence of people with neurological disabilities. (2 The Task Force has summarized the significant benefits that can follow from the establishment of a dedicated and cost effective neurological rehabilitation service including functional improvement, reduction of unnecessary complications, better coordination and use of limited resources, improved opportunities for education, training and research and a clear point of contact for the disabled person. (3 The Task Force recommends minimum standards for the prevention of neurological disability including access to health education, genetic counselling and emergency resources. The Task Force also encourages governments to invest in improved legislation for accident prevention. (4 The Task Force has outlined some minimum standards for the staffing of a neurological rehabilitation service including improved training both for neurologists and rehabilitation physicians. Such training could include a cross-national training programme both for physicians and other health care staff. (5 The Task Force supports a two-tier system of

The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD.

  19. Autoimmune channelopathies in paraneoplastic neurological syndromes. (United States)

    Joubert, Bastien; Honnorat, Jérôme


    Paraneoplastic neurological syndromes and autoimmune encephalitides are immune neurological disorders occurring or not in association with a cancer. They are thought to be due to an autoimmune reaction against neuronal antigens ectopically expressed by the underlying tumour or by cross-reaction with an unknown infectious agent. In some instances, paraneoplastic neurological syndromes and autoimmune encephalitides are related to an antibody-induced dysfunction of ion channels, a situation that can be labelled as autoimmune channelopathies. Such functional alterations of ion channels are caused by the specific fixation of an autoantibody upon its target, implying that autoimmune channelopathies are usually highly responsive to immuno-modulatory treatments. Over the recent years, numerous autoantibodies corresponding to various neurological syndromes have been discovered and their mechanisms of action partially deciphered. Autoantibodies in neurological autoimmune channelopathies may target either directly ion channels or proteins associated to ion channels and induce channel dysfunction by various mechanisms generally leading to the reduction of synaptic expression of the considered channel. The discovery of those mechanisms of action has provided insights on the regulation of the synaptic expression of the altered channels as well as the putative roles of some of their functional subdomains. Interestingly, patients' autoantibodies themselves can be used as specific tools in order to study the functions of ion channels.

  20. Neurology referrals to a liaison psychiatry service.

    LENUS (Irish Health Repository)

    Fitzgerald, P


    The objective of the present study was to assess the activity of the Liaison Psychiatry service of Cork University Hospital in relation to all in-patient neurology referrals over a 12-month period. Of 1685 neurology admissions, 106 (6%) were referred to liaison psychiatry for assessment. 91 referrals (86%) met criteria for a psychiatric disorder according to DSM-IV, the commonest being major depression (24%) and somatoform disorder (23%). Patients with multiple sclerosis or epilepsy comprised nearly half of all referrals (48 cases; 45%). Approximately 20% of M.S. in-patients (21 cases) were referred for psychiatric assessment, with the corresponding figure in epilepsy being 25% (18 cases). Although only 106 (6%) neurology in-patients were referred to liaison psychiatry, psychiatric diagnoses were documented in 327 (20%) discharge forms, presumably reflecting previous diagnosis. The above findings indicate that psychiatric illness is common among neurology inpatients screened by liaison psychiatry yet referral rates are relatively low in terms of the overall number of neurology in-patients. Psychiatric disorders were diagnosed in 86% of referrals indicating high concordance between neurologists and liaison psychiatry regarding the presence of a psychiatric disorder.

    Medrano, V; Mallada-Frechin, J; Delibes, C; Fernandez-Izquierdo, S; Piqueras-Rodriguez, L

    Some of the users attended in a Neurology service consist of the inmate population in a prison. The aim of this study is to analyse all the proposals referred from the Alicante II Prison Centre to a Neurology service. We analyse and describe the clinical characteristics of patients referred from the Alicante II Prison Centre to the Neurology service at the Centro Sanitario Integrado in Villena between the years 2003 and 2006. This analysis involved the following variables: age, sex, personal history, reason for visiting and diagnosis. A total of 88 proposals were recorded. The mean age of the patients was 35 years (84 males/4 females). A total of 15 patients did not attend their appointment (17%). Positive serology for the human immunodeficiency virus was found in 18% of patients. The most frequent reason for visiting was headache (32%), followed by seizures (25%) and, thirdly, vascular pathologies (13%). In a group of 16 patients (18%) the main diagnosis was established as being some kind of psychiatric disorder (anxiety, depression, simulation). No studies have been published in the literature that analyse the clinical characteristics of patients from prisons referred to a Neurology service. The high percentage of patients who do not attend their appointment and the high percentage of psychiatric disorders that are diagnosed within this group of patients are especially noteworthy. However, and as can be observed in the general population, headache is still the most common reason for visiting. Nevertheless, the group of neurological diagnoses that are most frequently attended is epilepsy.

  3. Neurology and the Internet: a review. (United States)

    Moccia, Marcello; Brigo, Francesco; Tedeschi, Gioacchino; Bonavita, Simona; Lavorgna, Luigi


    Nowadays, the Internet is the major source to obtain information about diseases and their treatments. The Internet is gaining relevance in the neurological setting, considering the possibility of timely social interaction, contributing to general public awareness on otherwise less-well-known neurological conditions, promoting health equity and improving the health-related coping. Neurological patients can easily find several online opportunities for peer interactions and learning. On the other hand, neurologist can analyze user-generated data to better understand patient needs and to run epidemiological studies. Indeed, analyses of queries from Internet search engines on certain neurological diseases have shown a strict temporal and spatial correlation with the "real world." In this narrative review, we will discuss how the Internet is radically affecting the healthcare of people with neurological disorders and, most importantly, is shifting the paradigm of care from the hands of those who deliver care, into the hands of those who receive it. Besides, we will review possible limitations, such as safety concerns, financial issues, and the need for easy-to-access platforms.

    Collado-Vázquez, Susana; Martínez-Martínez, Ariadna; Cano-de-la-Cuerda, Roberto


    The portrayal of neurological disability and deficiency on television has not always been approached in the same way, but has instead tended to reflect the standpoint taken by society with regard to these issues and how they are dealt with according to the prevailing conceptions and values at each particular time. To address the appearance of neurological pathologies in television series and to ponder on the image they have in such contexts. Deficiency and disability of neurological origin have often been depicted on television in series, telefilms and documentaries, and in a wide variety of ways. Here we examine different television series and how they have dealt with neurological pathology, its diagnosis and its treatment, as well as the figure of the healthcare professional and social-familial adaptation. Examples cited include series such as House MD, Glee, American Horror Story, Homeland or Game of Thrones. Television series are a useful tool for making some neurological pathologies better known to the public and for dispelling the myths surrounding others, provided that the pathologies are dealt with in a realistic manner, which is not always the case. More care should be taken with regard to the way in which health professionals are portrayed in television series, as it is not always done correctly and may mislead viewers, who take what they see on the TV as being real.

  5. Neurological Manifestations of Medical Child Abuse. (United States)

    Doughty, Katharine; Rood, Corey; Patel, Anup; Thackeray, Jonathan D; Brink, Farah W


    Medical child abuse occurs when a child receives unnecessary and harmful, or potentially harmful, medical care at the instigation of a caretaker through exaggeration, falsification, or induction of symptoms of illness in a child. Neurological manifestations are common with this type of maltreatment. We sought to review common reported neurological manifestations that may alert the clinician to consider medical child abuse. In addition, the possible sequelae of this form of child maltreatment is discussed, as well as practice recommendations for establishing the diagnosis and stopping the abuse once it is identified. A review of the medical literature was conducted regarding the reported neurological presentations of this entity. Neurological manifestations of medical child abuse include false reports of apparent life-threatening events and seizures and reports of induction of symptoms from poisoning. Failure to correlate objective findings with subjective complaints may lead to unnecessary and potentially harmful testing or treatment. This form of child maltreatment puts a child at significant risk of long-term morbidity and mortality. A wide variety of neurological manifestations have been reported in cases of medical child abuse. It is important for the practicing neurologist to include medical child abuse on the differential diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Coelho, Fernando Morgadinho; Castro, Luiz Henrique de; Fukujima, Marcia Maiumi; Adoni, Tarso; Rieder, Carlos Roberto de Mello; Bichuetti, Denis Bernardi; Prado, Gilmar Fernandes do; Gagliardi, Rubens Jose


    Brazil is a heterogeneous country with continental dimensions. The different characteristics of cultural, socioeconomic, and demographic status of the population drive different strategies for neurological care. This knowledge helps the understanding of the current scenario with the consequent possibility of preparing for future challenges. We used data from annual internal forms of the Brazilian Academy of Neurology (BAN) since 2006 and the survey for all BAN members (3,240) in 2016. The geographic distribution of BAN members in Brazil follows the demographic concentration of the population. Participation of members from big cities was the most prevalent, 18.7% of participants were young neurologists, and 36.7% of neurologists had more than of 20 years of neurological practice. The improvement of knowledge of neurological practice in Brazil will be useful for BAN leadership in planning future actions. The BAN must make an effort to aggregate a greater number of neurologists, offering updating support contributing to health policies to disseminate neurological care in Brazil.

  7. Problem neurology residents: a national survey. (United States)

    Tabby, David S; Majeed, Muhammed H; Schwartzman, Robert J


    Problem residents are found across most medical specialties at a prevalence of about 10%. This study was designed to explore the prevalence and causes of problem neurology residents and to compare neurology programs' responses and outcomes. Directors of 126 US neurology residency programs were sent an electronic survey. We collected data on demographics, first and all "identifiers" of problem residents, and year of training in which the problem was found. We asked about observable signs, etiology, and who performed remediation. We asked what resources were used and what outcomes occurred. Ninety-five program directors completed surveys (75% response rate). Almost all neurology programs have problem residents (81%). Age, sex, marital status, being a US native, or attending a US medical school had no effect on problem status. Being a parent carried a lower likelihood of problems (32%). Most commonly the problem is acted on during the first year of training. Faculty members without defined educational roles were the most frequent first identifiers. Program directors were the most common remediators. The most common remediation techniques were increasing supervision and assigning a faculty mentor. Graduate medical education office and psychiatric or psychological counseling services were most often used. Eleven percent of problem residents required a program for impaired physicians and 14% required a leave of absence. Sixteen percent were dismissed from their programs. The prevalence of problem residents in neurology is similar to other disciplines, and various resources are available to remediate them.

  8. Dengue: a new challenge for neurology

    Directory of Open Access Journals (Sweden)

    Marzia Puccioni-Sohler


    Full Text Available Dengue infection is a leading cause of illness and death in tropical and subtropical regions of the world. Forty percent of the world’s population currently lives in these areas. The clinical picture resulting from dengue infection can range from relatively minor to catastrophic hemorrhagic fever. Recently, reports have increased of neurological manifestations. Neuropathogenesis seems to be related to direct nervous system viral invasion, autoimmune reaction, metabolic and hemorrhagic disturbance. Neurological manifestations include encephalitis, encephalopathy, meningitis, Guillain-Barré syndrome, myelitis, acute disseminated encephalomyelitis, polyneuropathy, mononeuropathy, and cerebromeningeal hemorrhage. The development of neurological symptoms in patients with positive Immunoglobulin M (IgM dengue serology suggests a means of diagnosing the neurological complications associated with dengue. Viral antigens, specific IgM antibodies, and the intrathecal synthesis of dengue antibodies have been successfully detected in cerebrospinal fluid. However, despite diagnostic advancements, the treatment of neurological dengue is problematic. The launch of a dengue vaccine is expected to be beneficial.

    Middleton, P; Montero, C


    To review the research on the effects and indications of eccentric muscular contraction in the athlete. We searched the Medline database using the key words eccentric and negative work for reports of eccentric muscular contraction published from 1993 to 2004. The physiologic features of eccentric contraction remain unknown but significantly differ from concentric contraction. Eccentric contraction has a specific effect: during sports practice, it permits the muscular and tendinous complex to support strain and strengthens the muscular action of articular stabilization. But eccentric contraction produces injuries: delayed-onset muscle soreness, and muscle rupture and tendinous injuries such as luxation, rupture, and tendinitis. Treatment and prevention must have controlled protocols. In therapy, eccentric contraction must be realized at progressive speeds and resistances. Prevention of tendinous injury necessitates quantifying eccentric activity during training.

    Meregalli, Mirella; Farini, Andrea; Belicchi, Marzia; Parolini, Daniele; Cassinelli, Letizia; Razini, Paola; Sitzia, Clementina; Torrente, Yvan


    Muscular dystrophies are heritable and heterogeneous neuromuscular disorders characterized by the primary wasting of skeletal muscle, usually caused by mutations in the proteins forming the link between the cytoskeleton and the basal lamina. As a result of mutations in the dystrophin gene, Duchenne muscular dystrophy patients suffer from progressive muscle atrophy and an exhaustion of muscular regenerative capacity. No efficient therapies are available. The evidence that adult stem cells were capable of participating in the regeneration of more than their resident organ led to the development of potential stem cell treatments for degenerative disorder. In the present review, we describe the different types of myogenic stem cells and their possible use for the progression of cell therapy in Duchenne muscular dystrophy. © 2012 The Authors Journal compilation © 2012 FEBS.

  18. Emergency Neurologic Life Support: Meningitis and Encephalitis. (United States)

    Gaieski, David F; Nathan, Barnett R; O'Brien, Nicole F


    Bacterial meningitis and viral encephalitis, particularly herpes simplex encephalitis, are severe neurological infections that, if not treated promptly and effectively, lead to poor neurological outcome or death. Because treatment is more effective if given early, the topic of meningitis and encephalitis was chosen as an Emergency Neurological Life Support protocol. This protocol provides a practical approach to recognition and urgent treatment of bacterial meningitis and encephalitis. Appropriate imaging, spinal fluid analysis, and early empiric treatment is discussed. Though uncommon in its full form, the typical clinical triad of headache, fever, and neck stiffness should alert the clinical practitioner to the possibility of a central nervous system infection. Early attention to the airway and maintaining normotension is crucial in treatment of these patients, as is rapid treatment with anti-infectives and, in some cases, corticosteroids.

  19. A national neurological excellence centers network. (United States)

    Pazzi, S; Cristiani, P; Cavallini, A


    The most relevant problems related to the management of neurological disorders are (i) the frequent hospitalization in nonspecialist departments, with the need for neurological consultation, and (ii) the frequent requests of GPs for highly specialized investigations that are very expensive and of little value in arriving at a correct diagnosis. In 1996, the Consorzio di Bioingegneria e Informatica Medica in Italy realized the CISNet project (in collaboration with the Consorzio Istituti Scientifici Neuroscienze e Tecnologie Biomediche and funded by the Centro Studi of the National Public Health Council) for the implementation of a national neurological excellence centers network (CISNet). In the CISNet project, neurologists will be able to give on-line interactive consultation and off-line consulting services identifying correct diagnostic/therapeutic procedures, evaluating the need for both examination in specialist centers and admission to specialized centers, and identifying the most appropriate ones.

  20. The History of Reimbursements in Neurology

    Directory of Open Access Journals (Sweden)

    Shaheen E Lakhan


    Full Text Available The Patient Protection and Affordable Care Act (PPACA addresses consumer protection, employer-provided insurance coverage, as well as the government's role in providing health care access to the most vulnerable populations. Within the practice of neurology, the PPACA has the challenging goal of reconciling the needs of the growing elderly population with the financial barriers to costly yet available health care services. To bridge that gap, all health care professionals working in the field of neurology must reflect on the effect previous Medicare reimbursement policies have had on the current practice of neurology, and utilize lessons learned in recent years. The test of time will tell whether the PPACA will achieve the goal of decreasing in health care spending while ensuring quality universal healthcare services.

  1. Neurological complications of solid organ transplantation

    Directory of Open Access Journals (Sweden)

    José Luiz Pedroso

    Full Text Available ABSTRACT Solid organ transplantation is a significant development in the treatment of chronic kidney, liver, heart and lung diseases. This therapeutic approach has increased patient survival and improved quality of life. New surgical techniques and immunosuppressive drugs have been developed to achieve better outcomes. However, the variety of neurological complications following solid organ transplantation is broad and carries prognostic significance. Patients may have involvement of the central or peripheral nervous system due to multiple causes that can vary depending on time of onset after the surgical procedure, the transplanted organ, and the intensity and type of immunosuppressive therapy. Neurological manifestations following solid organ transplantation pose a diagnostic challenge to medical specialists despite extensive investigation. This review aimed to provide a practical approach to help neurologists and clinicians assess and manage solid organ transplant patients presenting with acute or chronic neurological manifestations.

  2. Nuclear Medicine Imaging in Pediatric Neurology (United States)

    Akdemir, Ümit Özgür; Atay Kapucu, Lütfiye Özlem


    Nuclear medicine imaging can provide important complementary information in the management of pediatric patients with neurological diseases. Pre-surgical localization of the epileptogenic focus in medically refractory epilepsy patients is the most common indication for nuclear medicine imaging in pediatric neurology. In patients with temporal lobe epilepsy, nuclear medicine imaging is particularly useful when magnetic resonance imaging findings are normal or its findings are discordant with electroencephalogram findings. In pediatric patients with brain tumors, nuclear medicine imaging can be clinically helpful in the diagnosis, directing biopsy, planning therapy, differentiating tumor recurrence from post-treatment sequelae, and assessment of response to therapy. Among other neurological diseases in which nuclear medicine has proved to be useful are patients with head trauma, inflammatory-infectious diseases and hypoxic-ischemic encephalopathy. PMID:27299282

  4. Outside in: The matrix as a modifier of muscular dystrophy. (United States)

    Quattrocelli, Mattia; Spencer, Melissa J; McNally, Elizabeth M


    Muscular dystrophies are genetic conditions leading to muscle degeneration and often, impaired regeneration. Duchenne Muscular Dystrophy is a prototypical form of muscular dystrophy, and like other forms of genetically inherited muscle diseases, pathological progression is variable. Variability in muscular dystrophy can arise from differences in the manner in which the primary mutation impacts the affected protein's function; however, clinical heterogeneity also derives from secondary mutations in other genes that can enhance or reduce pathogenic features of disease. These genes, called genetic modifiers, regulate the pathophysiological context of dystrophic degeneration and regeneration. Understanding the mechanistic links between genetic modifiers and dystrophic progression sheds light on pathologic remodeling, and provides novel avenues to therapeutically intervene to reduce muscle degeneration. Based on targeted genetic approaches and unbiased genomewide screens, several modifiers have been identified for muscular dystrophy, including extracellular agonists of signaling cascades. This review will focus on identification and possible mechanisms of recently identified modifiers for muscular dystrophy, including osteopontin, latent TGFβ binding protein 4 (LTBP4) and Jagged1. Moreover, we will review the investigational approaches that aim to target modifier pathways and thereby counteract dystrophic muscle wasting. Copyright © 2016 Elsevier B.V. All rights reserved.

  5. Media's influence on the drive for muscularity in undergraduates. (United States)

    Cramblitt, Brooke; Pritchard, Mary


    Although research has found that body ideals presented by the media influence women's body dissatisfaction, less is known about media's influence on men's body satisfaction. An online survey examining media use, the drive for muscularity, and internalization of appearance and body shape ideals was given to a sample of 311 participants comprised of both men and women. Results indicated (a) the more time men and women reported watching television, the higher their reported drive for muscularity (b) total hours of viewing sports-related, image-focused, and entertainment television related to increased drive for muscularity in women (c) drive for muscularity in men related to watching image-focused television and reading men's health magazines, and (d) internalization of athletic attitudes towards appearance mediated the relationship between total television watched and drive for muscularity in both genders. Clinicians may wish to utilize these findings when treating men and women suffering from drive for muscularity and body dysmorphia. © 2013 Elsevier Ltd. All rights reserved.

  6. Autoimmune Neurology of the Central Nervous System. (United States)

    Tobin, W Oliver; Pittock, Sean J


    This article reviews the rapidly evolving spectrum of autoimmune neurologic disorders with a focus on those that involve the central nervous system, providing an understanding of how to approach the diagnostic workup of patients presenting with central nervous system symptoms or signs that could be immune mediated, either paraneoplastic or idiopathic, to guide therapeutic decision making. The past decade has seen a dramatic increase in the discovery of novel neural antibodies and their targets. Many commercial laboratories can now test for these antibodies, which serve as diagnostic markers of diverse neurologic disorders that occur on an autoimmune basis. Some are highly specific for certain cancer types, and the neural antibody profiles may help direct the physician's cancer search. The diagnosis of an autoimmune neurologic disorder is aided by the detection of an objective neurologic deficit (usually subacute in onset with a fluctuating course), the presence of a neural autoantibody, and improvement in the neurologic status after a course of immunotherapy. Neural autoantibodies should raise concern for a paraneoplastic etiology and may inform a targeted oncologic evaluation (eg, N-methyl-D-aspartate [NMDA] receptor antibodies are associated with teratoma, antineuronal nuclear antibody type 1 [ANNA-1, or anti-Hu] are associated with small cell lung cancer). MRI, EEG, functional imaging, videotaped evaluations, and neuropsychological evaluations provide objective evidence of neurologic dysfunction by which the success of immunotherapy may be measured. Most treatment information emanates from retrospective case series and expert opinion. Nonetheless, early intervention may allow reversal of deficits in many patients and prevention of future disability.

  7. Rare Neurological Complications After Sleeve Gastrectomy. (United States)

    Tabbara, Malek; Carandina, Sergio; Bossi, Manuela; Polliand, Claude; Genser, Laurent; Barrat, Christophe


    Bariatric surgery is considered to be the most effective treatment of morbid obesity and improvement of obesity-related comorbidities, such as type II diabetes. However, both peripheral and central neurological complications can occur after bariatric surgery. Such complications tend to occur more frequently after bypass surgery than after sleeve gastrectomy (SG). The objective of this study was to identify the patients that presented post-operative neurological complications after undergoing SG and describe the incidence, presentation, and management of these complications. This was a retrospective study of 592 cases of SG performed between 2009 and 2014 with a special focus on patients who presented neurological complications. Of the 592 SG cases, only seven (1.18 %) patients presented neurological complications. All patients had uneventful post-operative course, but all reported feeding difficulties, accompanied by severe dysphagia, and rapid weight loss, with a mean weight loss of 35 kg (30-40 kg) 3 months after SG. All patients were readmitted owing to neurological symptoms that included paresthesia, abolition of deep tendon reflexes of the lower limbs, muscle pain, and motor and sensitive deficits in some cases. There were two cases of Wernicke's encephalopathy. All patients were treated for neuropathy secondary to vitamin B1 deficiency and had a significant improvement and/or resolution of their symptoms. Neurological complications after SG are rare and are often preceded by gastrointestinal symptoms, rapid weight loss, and lack of post-operative vitamin supplementation. Re-hospitalization and multidisciplinary team management are crucial to establish the diagnosis and initiate treatment.

  8. Postmalaria Neurologic Syndrome: A Case Report

    Cheng-Fang Hsieh


    Full Text Available Neurologic signs and symptoms are common in acute malarial infection. However, after the parasites have been cleared from the blood and patients recover full consciousness, neurologic or psychiatric symptoms may occur or recur within 2 months after the acute illness. This phenomenon is called “postmalaria neurologic syndrome” (PMNS. We present a 50-year-old man who returned from the Republic of Malawi and soon developed Plasmodium falciparum malaria. Cerebral malaria, renal failure, hepatic failure, diffuse intravascular coagulation with thrombocytopenia, and upper gastrointestinal bleeding were noted during the acute stage. He was admitted to the infectious diseases ward and treated for 3 weeks. He was free from clinical general symptoms and parasites in blood smear when discharged. However, 2 weeks after discharge, he began to experience severe headache, dizziness, diplopia, mild hand tremor, unsteady gait, and easy falling. When readmitted to the neurologic ward, he presented with irritability, delirium, visual hallucination, and strange behavior. Neurologic examination was normal except for mild general weakness and evident truncal ataxia when walking. Brain magnetic resonance imaging revealed no structural lesions, and electroencephalography showed diffuse cortical dysfunction. Cerebral spinal fluid profile exhibited cytoalbuminologic dissociation. Brain single photon emission computed tomography showed diffuse cerebral parenchymal disorder. Nerve conduction studies revealed early sensory predominant polyneuropathy. The unsteadiness persisted for the initial 2 weeks of hospitalization until corticosteroid was administered. Intravenous methylprednisolone (80 mg/day was continued for 3 days, followed by oral prednisolone (45 mg/day. His unsteadiness improved gradually after medication, and he absconded from the hospital on the 9th day of corticosteroid treatment with clear consciousness and free ambulation. The manifestation of PMNS is

  9. Quantitative analysis of muscular wastings of lower limbs in Duchenne muscular dystrophy by computed tomography

    Horikawa, Hirosei; Konagaya, Masaaki; Takayanagi, Tetsuya; Otsuji, Hideaki


    We quantitatively evaluated the muscular wastings of lower extremities in Duchenne muscular dystrophy (DMD) by computed tomography (CT). The subjects were 21 cases of DMD (an ambulant case and 20 wheelchair-ridden cases, ages ranging from 10 to 21 years old) and 4 control males. The CT scan was carried out at the mid-level between lesser trochanter and medial condyle of femur and the largest diameter level of lower leg. The density and the cross-sectional area of each muscle were measured on the CT image. The average CT number of normal muscle was varying from 40 to 60, as well as that of fat was -115. Then we calculated CT index of each muscle denoted as follows: CT index = [average CT number of muscle-(-115)] X(cross-sectional area of each muscle). The measurements of muscle strength and serum CK level were performed and their relationships to CT index were examined. The results were achieved as follows: 1) Wheelchair-ridden cases with DMD showed severe decrease in the average CT number and the CT index of each muscle with normal controls. With progression, the average CT number and the CT index were reduced. But gracilis muscle and sartorius muscle were relatively spared in comparison with other muscles. 2) There was positive correlation between the CT index and the muscle strength in triceps surae muscle, hamstrings muslce and quardriceps femoris muscle. 3) The CT index of whole thigh muscles and that of whole lower leg muscles were highly correlated to serum CK level. These results suggest that the quantitative analysis of muscle CT is an useful measurement for assessement of muscular wastings in DMD. (author)

    Richard Bright was one of the famous triumvirate of Guy's Hospital physicians in the Victorian era. Remembered for his account of glomerulonephritis (Bright's disease) he also made many important and original contributions to medicine and neurology. These included his work on cortical epileptogenesis, descriptions of simple partial (Jacksonian) seizures, infantile convulsions, and a variety of nervous diseases. Most notable were his reports of neurological studies including papers on traumatic tetanus, syringomyelia, arteries of the brain, contractures of spinal origin, tumours of the base of the brain, and narcolepsy. His career and these contributions are outlined. Copyright 2009 S. Karger AG, Basel.

  12. Neurological Complications in Controlled HIV Infection. (United States)

    Crossley, Kate M; Brew, Bruce J


    In recent years, there have been great advances in therapies for human immunodeficiency virus (HIV) that have allowed suppression of the virus and its effects on the body. Despite this progress, neurological complications persist in HIV-infected individuals. In this review we consider the possible ways that HIV might cause neurotoxicity and neuroinflammation. We discuss the spectrum of neurological disorders caused by HIV and its treatment, with a particular focus on both HIV-associated neurocognitive disorders and peripheral neuropathies. Since there has been a shift to HIV being a chronic illness, we also review the increasing prevalence of cerebrovascular disease and neurodegenerative disorders.

    Full Text Available With the advent of research on stem cell therapy for various diseases, an important need was felt in the field of neurological diseases. While congenital lesion may not be amenable to stem cell therapy completely, there is a scope of partial improvement in the lesions and halt in further progression. Neuro degenerative lesions like Parkinson′s disease, multiple sclerosis and amyotrophic lateral sclerosis have shown improvement with stem cell therapy. This article reviews the available literature and summarizes the current evidence in the various neurologic diseases amenable to stem cell therapy, the plausible mechanism of action, ethical concerns with insights into the future of stem cell therapy.

  14. How to write a neurology case report. (United States)

    Rison, Richard A


    Neurology case reports have a long history of transmitting important medical information across many generations for the improvement of patient care. Case reports contribute much to the physician's knowledge base from which treatment hypotheses and ideas form. Elements of a modern case report, as presented in the CARE (CAse REport) guidelines, include the abstract, introduction, case presentation, discussion, conclusion, patient's perspective, and consent statement. The sections are described here, as well as the application of CARE guidelines to a published neuromuscular case report. Writing case reports offer an ideal opportunity for neurologists to publish interesting case findings and carry on the tradition of neurologic case reporting.

    Karunaratne, Kushan; Taube, David; Khalil, Nofal; Perry, Richard; Malhotra, Paresh A


    Neurological complications from renal replacement therapy contribute significantly to morbidity and mortality in patients with renal failure. Such complications can affect either the central or peripheral nervous systems. Most neurological disturbances associated with the uraemic state do not respond fully to renal replacement therapy. There are also complications specifically associated with dialysis and transplantation. A multidisciplinary approach, involving both nephrologists and neurologists, is critical for the diagnosis and effective management of these disorders. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  17. Neurologic aspects of lymphoma and leukemias. (United States)

    McCoyd, Matthew; Gruener, Gregory; Foy, Patrick


    The lymphomas and leukemias are a heterogenous group of hematologic malignancies with protean manifestations. Neurologic sequelae of the diseases have been recognized since the time the conditions were first described in the mid-1800s. Although our understanding of the various presentations of these blood disorders evolved along with our knowledge of malignancies, accurate diagnosis can still be difficult. It is critical for neurologists to have a high index of clinical suspicion to appropriately recognize their heralding features. This review's focus is the relevant clinical neurologic features and diagnostic studies that identify leukemias and lymphomas affecting the nervous system. © 2014 Elsevier B.V. All rights reserved.

  1. Treatment of infantile-onset spinal muscular atrophy with nusinersen: a phase 2, open-label, dose-escalation study. (United States)

    Finkel, Richard S; Chiriboga, Claudia A; Vajsar, Jiri; Day, John W; Montes, Jacqueline; De Vivo, Darryl C; Yamashita, Mason; Rigo, Frank; Hung, Gene; Schneider, Eugene; Norris, Daniel A; Xia, Shuting; Bennett, C Frank; Bishop, Kathie M


    Nusinersen is a 2'-O-methoxyethyl phosphorothioate-modified antisense drug being developed to treat spinal muscular atrophy. Nusinersen is specifically designed to alter splicing of SMN2 pre-mRNA and thus increase the amount of functional survival motor neuron (SMN) protein that is deficient in patients with spinal muscular atrophy. This open-label, phase 2, escalating dose clinical study assessed the safety and tolerability, pharmacokinetics, and clinical efficacy of multiple intrathecal doses of nusinersen (6 mg and 12 mg dose equivalents) in patients with infantile-onset spinal muscular atrophy. Eligible participants were of either gender aged between 3 weeks and 7 months old with onset of spinal muscular atrophy symptoms between 3 weeks and 6 months, who had SMN1 homozygous gene deletion or mutation. Safety assessments included adverse events, physical and neurological examinations, vital signs, clinical laboratory tests, cerebrospinal fluid laboratory tests, and electrocardiographs. Clinical efficacy assessments included event free survival, and change from baseline of two assessments of motor function: the motor milestones portion of the Hammersmith Infant Neurological Exam-Part 2 (HINE-2) and the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) motor function test, and compound motor action potentials. Autopsy tissue was analysed for target engagement, drug concentrations, and pharmacological activity. HINE-2, CHOP-INTEND, and compound motor action potential were compared between baseline and last visit using the Wilcoxon signed-rank test. Age at death or permanent ventilation was compared with natural history using the log-rank test. The study is registered at, number NCT01839656. 20 participants were enrolled between May 3, 2013, and July 9, 2014, and assessed through to an interim analysis done on Jan 26, 2016. All participants experienced adverse events, with 77 serious adverse events reported in

  3. Molecular analysis of facioscapulohumeral muscular dystrophy (FSHD)

    Energy Technology Data Exchange (ETDEWEB)

    Upadhyaya, M.; Maynard, J.; Osborn, M. [Institute of Medical Genetics, Cardiff (United Kingdom)] [and others


    Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant disorder characterized by progressive muscle weakness. The disease locus maps to 4q35 and is associated with a de novo DNA rearrangement, detected by a probe p13E-11 (D4F104S1) which maps proximal to the disease locus. An informative distal flanking marker for this condition is still required. Using p13E-11, we have analyzed 35 FSHD families in which the disease is apparently associated with a new mutation. Twenty three of these cases were found to have a smaller rearranged DNA fragment which was not present in either of the parents. Pulsed-field gel analysis of 5 of these families also revealed evidence of DNA deletion. During the course of this study, we identified one case with a DNA rearrangement which was also present in the unaffected mother, but at very low intensity. This finding has been confirmed by pulsed-field gel analysis, and indicates that the mother is probably a gonosomal mosaic. In order to saturate the FSHD region with new DNA markers, a laser microdissection and microcloning technique was used to construct a genomic library from the distal end of chromosome 4. Of the 72 microclones analyzed, 42 mapped into the relevant 4q35 region. 4 sequences were conserved and may be considered potential candidate genes for FSHD. The microclones mapping to 4q35 are under study to identify additional polymorphic markers for the FSHD region.

  4. Advances in spinal muscular atrophy therapeutics. (United States)

    Parente, Valeria; Corti, Stefania


    Spinal muscular atrophy (SMA) is a progressive, recessively inherited neuromuscular disease, characterized by the degeneration of lower motor neurons in the spinal cord and brainstem, which leads to weakness and muscle atrophy. SMA currently represents the most common genetic cause of infant death. SMA is caused by the lack of survival motor neuron (SMN) protein due to mutations, which are often deletions, in the SMN1 gene. In the absence of treatments able to modify the disease course, a considerable burden falls on patients and their families. Greater knowledge of the molecular basis of SMA pathogenesis has fuelled the development of potential therapeutic approaches, which are illustrated here. Nusinersen, a modified antisense oligonucleotide that modulates the splicing of the SMN2 mRNA transcript, is the first approved drug for all types of SMA. Moreover, the first gene therapy clinical trial using adeno-associated virus (AAV) vectors encoding SMN reported positive results in survival and motor milestones achievement. In addition, other strategies are in the pipeline, including modulation of SMN2 transcripts, neuroprotection, and targeting an increasing number of other peripheral targets, including the skeletal muscle. Based on this premise, it is reasonable to expect that therapeutic approaches aimed at treating SMA will soon be changed, and improved, in a meaningful way. We discuss the challenges with regard to the development of novel treatments for patients with SMA, and depict the current and future scenarios as the field enters into a new era of promising effective treatments.

  5. Nutritional Challenges in Duchenne Muscular Dystrophy. (United States)

    Salera, Simona; Menni, Francesca; Moggio, Maurizio; Guez, Sophie; Sciacco, Monica; Esposito, Susanna


    Neuromuscular diseases (NMDs) represent a heterogeneous group of acquired or inherited conditions. Nutritional complications are frequent in NMDs, but they are sometimes underestimated. With the prolongation of survival in patients with NMDs, there are several nutritional aspects that are important to consider, including the deleterious effects of overnutrition on glucose metabolism, mobility, and respiratory and cardiologic functions; the impact of hyponutrition on muscle and ventilatory function; constipation and other gastrointestinal complications; chewing/swallowing difficulties with an increased risk of aspiration that predisposes to infectious diseases and respiratory complications; as well as osteoporosis with an associated increased risk of fractures. The aim of this review is to provide a comprehensive analysis of the nutritional aspects and complications that can start in children with Duchenne muscular dystrophy (DMD) and increase with ageing. These aspects should be considered in the transition from paediatric clinics to adult services. It is shown that appropriate nutritional care can help to improve the quality of life of DMD patients, and a multidisciplinary team is needed to support nutrition challenges in DMD patients. However, studies on the prevalence of overnutrition and undernutrition, gastrointestinal complications, infectious diseases, dysphagia, and reduced bone mass in the different types of NMDs are needed, and appropriate percentiles of weight, height, body mass index, and body composition appear to be extremely important to improve the management of patients with NMD.

    Gauld, Leanne M; Keeling, Lucy A; Shackleton, Claire E; Sly, Peter D


    Spinal muscular atrophy (SMA) causes respiratory compromise that is difficult to assess in young children. The forced oscillation technique (FOT) is commercially available for children as young as 2 years of age and is nonvolitional. The aim of this study was to assess the usefulness of FOT in young children with SMA. Children with SMA aged resistance at 8 Hz (Rrs8) (mean z score, +0.66; SD, 1.34; P = .12) were abnormal. Four children performed spirometry. Linear relationships to Xrs8 exist: FVC (R2, 0.54), unassisted PCF (R2, 0.33), assisted PCF (R2, 0.43), and AHI (R2, 0.32). Over 12 months, Xrs8z score worsened (rate of change of +1.08, P change +0.51, P .05) was found between clinical characteristics and FOT values. FOT is feasible in young children with SMA, with abnormal values of reactance and resistance on grouped data, worsening over 12 months. Xrs8 is related to respiratory tests used to monitor progress in SMA (FVC, PCF, AHI). Further research on the value of FOT in managing individuals is warranted.

  8. Optimizing Bone Health in Duchenne Muscular Dystrophy

    Directory of Open Access Journals (Sweden)

    Jason L. Buckner


    Full Text Available Duchenne muscular dystrophy (DMD is an X-linked recessive disorder characterized by progressive muscle weakness, with eventual loss of ambulation and premature death. The approved therapy with corticosteroids improves muscle strength, prolongs ambulation, and maintains pulmonary function. However, the osteoporotic impact of chronic corticosteroid use further impairs the underlying reduced bone mass seen in DMD, leading to increased fragility fractures of long bones and vertebrae. These serious sequelae adversely affect quality of life and can impact survival. The current clinical issues relating to bone health and bone health screening methods in DMD are presented in this review. Diagnostic studies, including biochemical markers of bone turnover and bone mineral density by dual energy X-ray absorptiometry (DXA, as well as spinal imaging using densitometric lateral spinal imaging, and treatment to optimize bone health in patients with DMD are discussed. Treatment with bisphosphonates offers a method to increase bone mass in these children; oral and intravenous bisphosphonates have been used successfully although treatment is typically reserved for children with fractures and/or bone pain with low bone mass by DXA.

  13. Neurological disorders in children with autism

    Directory of Open Access Journals (Sweden)

    N. N. Zavadenko


    Full Text Available During a clinical examination of children with autistic spectrum disorders, attention should be drawn to both their major clinical manifestations and neurological comorbidities. The paper considers the mechanisms of autism-induced neurological disorders, the spectrum of which may include manifestations, such as retarded and disharmonic early psychomotor development; the specific features of sensory perception/processing; rigidity and monotony of motor and psychic reactions; motor disinhibition and hyperexcitability; motor stereotypies; uncoordinated movements; developmental coordination disorders (dyspraxia; impaired expressive motor skills; speech and articulation disorders; tics; epilepsy. It describes the specific features of neurological symptoms in Asperger’s syndrome, particularly in semantic-pragmatic language disorders, higher incidence rates of hyperlexia, motor and vocal tics. The incidence rate of epilepsy in autistic spectrum disorders is emphasized to be greater than the average population one. At the same time, the risk of epilepsy is higher in mentally retarded patients with autism. Identification of neurological disorders is of great importance in determining the tactics of complex care for patients with autistic spectrum disorders.

  16. Neurologic complications after solid organ transplantation. (United States)

    Senzolo, Marco; Marco, Senzolo; Ferronato, Cecilia; Cecilia, Ferronato; Burra, Patrizia; Patrizia, Burra


    Neurologic complications are common after solid organ transplantation and are associated with significant morbidity. Approximately one-third of transplant recipients experiences neurologic alterations with incidence ranging from 10% to 59%. The complications can be divided into such of those common to all types of transplant and others of those specific to transplanted organ. The most common complication seen with all types of transplanted organ is neurotoxicity attributable to immunosuppressive drugs, followed by seizures, opportunistic central nervous system (CNS) infections, cardiovascular events, encephalopathy and de novo CNS neoplasms. Amongst immunosuppressants, calcineurin inhibitors are the main drugs involved in neurotoxicity, leading to complications which ranges from mild symptoms, such as tremors and paresthesia to severe symptoms, such as disabling pain syndrome and leukoencephalopathy. Neurologic complications of liver transplantation are more common than that of other solid organ transplants (13-47%); encephalopathy is the most common CNS complication, followed by seizures; however, central pontine myelinolysis can appear in 1-8% of the patients leading to permanent disabilities or death. In kidney transplanted patients, stroke is the most common neurologic complication, whereas cerebral infarction and bleeding are more typical after heart transplantation. Metabolic, electrolyte and infectious anomalies represent common risk factors; however, identification of specific causes and early diagnosis are still difficult, because of patient's poor clinical status and concomitant systemic and metabolic disorders, which may obscure symptoms.

  20. The challenges of residents teaching neurology. (United States)

    Frank, Samuel A; Józefowicz, Ralph F


    Teaching is integrated into the daily practice of residents, and it is a skill necessary for practice as well as academics. The settings in which teaching and learning take place are ubiquitous but include classrooms, small groups, bedside rounds, and grand rounds. Given the learning environment of residency, neurology residents should have working knowledge of basic principles of effective teaching to make learning successful. Teaching also reinforces knowledge, and residents will likely be better practitioners if some basic skills of teaching are practiced. Neurology teaching techniques for residents are rarely addressed in the medical literature. Although information regarding teaching principles in medicine exists, there is little information regarding how residents teach. We examine and review some of the more effective methods and appreciated qualities in teachers, with a particular emphasis for the neurology resident. We also review whom neurologists need to teach and the various settings in which teaching may take place. Neurology residents encounter a variety of audiences in a variety of settings that require diverse teaching skills to effectively convey information to other providers as well as patients. The majority of these skills should be learned in residency to establish a foundation for teaching, regardless of future practice settings.

  1. [Cinema and neurology: early educational applications]. (United States)

    Collado-Vázquez, Susana; Carrillo, Jesús M


    Since its earliest days, cinema has been used in the teaching of neurology both to illustrate the professor's explanations and to make learning easier for students. To analyse some of the first applications of cinema to the teaching and learning of neurology. Shortly after the birth of the film projector it became apparent that it could be a valuable aid in teaching medicine, and especially neurology. Initially, actual recordings made by doctors themselves were used, and later documentaries, short films and feature films were employed as means of showing diagnostic and therapeutic methods, as well as different pathological signs, such as movement disorders. The intention was not to replace other methodologies but instead to complement them and to make the process of acquiring knowledge easier. Applying cinema in teaching is a useful way to portray the contents of different subjects, especially in the field of neurology, and to favour the acquisition of both specific and cross-disciplinary competences, with very positive results being obtained among students.

  2. Neurological complications of Zika virus infection. (United States)

    Carod-Artal, Francisco Javier


    Zika virus (ZIKV) disease is a vector-borne infectious disease transmitted by Aedes mosquitoes. Recently, ZIKV has caused outbreaks in most American countries. Areas covered: Publications about neurological complications of ZIKV infection retrieved from pubmed searchers were reviewed, and reference lists and relevant articles from review articles were also examined. Vertical/intrauterine transmission leads to congenital infection and causes microcephaly and congenital ZIKV syndrome. ZIKV preferentially infects human neural progenitor cells and triggers cell apoptosis. ZIKV RNA has been identified in foetal brain tissue and brains of microcephalic infants who died; amniotic fluid and placentas of pregnant mothers; and umbilical cord, cerebro-spinal fluid and meninges of newborns. The increase in the number of Guillain-Barre syndrome (GBS) cases during the ZIKV outbreak in the Americas provides epidemiological evidence for the link between ZIKV infection and GBS. Less frequently reported ZIKV neurological complications include encephalitis/meningoencephalitis, acute disseminated encephalomyelitis, myelitis, cerebrovascular complications (ischemic infarction; vasculopathy), seizures and encephalopathy, sensory polyneuropathy and sensory neuronopathy. Analysis of GBS incidence could serve as an epidemiological 'marker' or sentinel for ZIKV disease and other neurological complications associated to ZIKV. Expert commentary: An expanding spectrum of neurological complications associated with ZIKV infection is being recognised.

  5. The child neurology clinical workforce in 2015 (United States)

    Bale, James F.; Mintz, Mark; Joshi, Sucheta M.; Gilbert, Donald L.; Radabaugh, Carrie; Ruch-Ross, Holly


    Objectives: More than a decade has passed since the last major workforce survey of child neurologists in the United States; thus, a reassessment of the child neurology workforce is needed, along with an inaugural assessment of a new related field, neurodevelopmental disabilities. Methods: The American Academy of Pediatrics and the Child Neurology Society conducted an electronic survey in 2015 of child neurologists and neurodevelopmental disabilities specialists. Results: The majority of respondents participate in maintenance of certification, practice in academic medical centers, and offer subspecialty care. EEG reading and epilepsy care are common subspecialty practice areas, although many child neurologists have not had formal training in this field. In keeping with broader trends, medical school debts are substantially higher than in the past and will often take many years to pay off. Although a broad majority would choose these fields again, there are widespread dissatisfactions with compensation and benefits given the length of training and the complexity of care provided, and frustrations with mounting regulatory and administrative stresses that interfere with clinical practice. Conclusions: Although not unique to child neurology and neurodevelopmental disabilities, such issues may present barriers for the recruitment of trainees into these fields. Creative approaches to enhance the recruitment of the next generation of child neurologists and neurodevelopmental disabilities specialists will benefit society, especially in light of all the exciting new treatments under development for an array of chronic childhood neurologic disorders.

    Full Text Available Episodic transient neurological symptoms are an important set of problems presenting to a neurologist in his routine practice. Occasionally, detailed clinical history including past and family history supplemented with focused examination can bring out a rare cause for such symptoms. We describe in this report in a young male presenting with episodic focal neurological dysfunction, with family history of similar episodes in mother and brother. Examination showed features of pes cavus and peripheral neuropathy for which patient was asymptomatic. Mother and brother were established cases of hereditary neuropathy. Imaging on multiple occasions showed reversible white matter abnormalities. Clinical suspicion of X-linked Charcot-Marie-Tooth disease type 1 (CMT1X was confirmed with detection of mutation in Gap Junction B1 (GJB1 gene, which codes for connexin 32 protein (c.425G>A; p.R142Q hemizygous mutation. Though this mutation has been already reported in CMTX patients, it has not been associated with transient neurological dysfunctions. This is probably the first reported case of CMTX patient with transient neurological dysfunction from India, whose family members had similar episodes.

  10. Neurological aspects of human parvovirus B19 infection: a systematic review (United States)

    Barah, Faraj; Whiteside, Sigrid; Batista, Sonia; Morris, Julie


    Parvovirus B19 has been linked with various clinical syndromes including neurological manifestations. However, its role in the latter remains not completely understood. Although the last 10 years witnessed a surge of case reports on B19-associated neurological aspects, the literature data remains scattered and heterogeneous, and epidemiological information on the incidence of B19-associated neurological aspects cannot be accurately extrapolated. The aim of this review is to identify the characteristics of cases of B19-associated neurological manifestations. A computerized systematic review of existing literature concerning cases of B19-related neurological aspects revealed 89 articles describing 129 patients; 79 (61.2%) were associated with CNS manifestations, 41 (31.8%) were associated with peripheral nervous system manifestations, and 9 (7.0%) were linked with myalgic encephalomyelitis. The majority of the cases (50/129) had encephalitis. Clinical characteristic features of these cases were analyzed, and possible pathological mechanisms were also described. In conclusion, B19 should be included in differential diagnosis of encephalitic syndromes of unknown etiology in all age groups. Diagnosis should rely on investigation of anti-B19 IgM antibodies and detection of B19 DNA in serum or CSF. Treatment of severe cases might benefit from a combined regime of intravenous immunoglobulins and steroids. To confirm these outcomes, goal-targeted studies are recommended to exactly identify epidemiological scenarios and explore potential pathogenic mechanisms of these complications. Performing retrospective and prospective and multicenter studies concerning B19 and neurological aspects in general, and B19 and encephalitic syndromes in particular, are required. © 2014 The Authors.

  11. Paediatric neurological melioidosis: a rehabilitation case report. (United States)

    White, Meagan E; Hunt, Jacqueline; Connell, Cheraine; Langdon, Katherine


    Melioidosis is a rare condition, endemic to northern Australia and south-east Asia, caused by an infection from the bacteria Burkholderia pseudomallei. The largest epidemiological review to date describes 540 cases of melioidosis seen at Darwin Hospital, in northern Australia, over a 20-year period. Of these, 14 (less than 3%) presented with neurological manifestation, with three deaths. Reports of paediatric cases of melioidosis are rarer. In a review of paediatric cases in northern Australia only eight cases were identified in 10 years. Three of these patients presented with neurological melioidosis, of whom two died in hospital. Whilst the literature refers to prolonged periods of hospitalisation for survivors, the trajectory of functional recovery and process of rehabilitation has not been described. This is a case report describing a 14-year-old boy who presented to a remote medical post with acute neurological symptoms (vomiting, severe headache, ataxia, cranial nerve VI and VII palsy) and was referred to the tertiary paediatric hospital in Perth, Western Australia. Cranial magnetic resonance imaging showed an extensive infiltrative lesion in the posterior fossa and hydrocephalus. Diagnosis of neurological melioidosis required isolation of the pathogen by brain biopsy through sub-occipital craniotomy. Medical treatment included surgical management of hydrocephalus, parenteral antibiotic treatment with meropenem and then a prolonged course of oral co-trimoxazole, enteral feeding and tonal management with levodopa-carbidopa and botulinum toxin A injections. Associated neurological signs and symptoms (bradykinesia, tremor, dysphagia, aphasia, hypertonia, exotropia) required intensive rehabilitation to address functional deficits and to promote independence. The purpose of this case report is to document the functional recovery and rehabilitation process of a paediatric case of neurological melioidosis. Knowledge of the recovery pathway is important to add to the

    Pérez-Alvarez, F; Timoneda-Gallart, C

    The hypothesis of the emotional component of behaviors can be explained by a specific neurological mechanism was stated. A sample of 749 cases, all between 5 and 14 year old, with different behavioral and cognitive problems was selected from attendance to the Neuropediatric/Neuropsychopedagogic Unit from 1994 to 2000. A sub sample of 20 cases with PASS planning processing scoring less than 1SD was also selected. A design of mainly qualitative research according to case analysis was followed, behavioral data being provided by patients and their parents and analyzed with video recorder assistance. To avoid the study to be biased techniques as triangulation were applied. Quantitative cognitive data were obtained by using DN:CAS battery for diagnosis of PASS processing. A procedure for diagnosis and treatment of behaviors, previously reported, was followed. The cases of the sub sample were tested before and after emotional treatment without cognitive remediation, the results being tested by Student t. The responders were 82% according to not only the criterion of solution of the behavioral problem, for example, anorexia, psychosomatism, non neurological paroxysm an so on, but also, the sufficient amelioration assessed by the patients, their parents and the researchers. All cases, however, were required the disappearance of observable defensive behaviors in enough quantity to deduce an important maturation change. Significant difference was observed in planning. Defensive behaviors as masquerade behaviors are explained in the light of neurological reasons. The neurological processing of the sensibility of danger is emphasized according to the most recent knowledge. All behaviors can activate the neurological processing of danger feeling

  13. Advanced Practice Clinician Training for Neurology (United States)

    Cox, Lori; Ahmed, Aiesha


    Background The specialty of Neurology is faced with a fundamental problem of economics: supply and demand. The projected increase in provider supply is unlikely to keep up with projected increases in patient-care demand. Many large academic centers have used residents to meet this patient-care demand. However, the conflict between education of residents and patient-care needs has created a hindrance to both of those missions. Many specialties have been using advanced practice clinicians (APCs) to help address the need for patient care. In the setting of a residency program, this availability of APCs can help to alleviate patient-care demands for the resident and allow for better allocated educational time. Neurology has not historically been a popular choice for APCs and a standardized educational curriculum for a Neurology APC has not been established. Methods The authors share an example curriculum recently implemented for training new inpatient Neurology APCs. This curriculum includes a 12-week program complete with rotations through various subspecialties and proposes fundamental lecture topics for use in education. The authors share their expectations for clinical duties that evolve over the course of the 12-week program in conjunction with expectations for increasing clinical knowledge as well as efficiency in system utilization. Conclusion The addition of APCs to support a busy inpatient Neurology practice has obvious beneficial implications but the integration and education of this new staff must be structured and well-designed to support the confidence of the APC in both their knowledge and their role as an indispensable member of the care team.

    Full Text Available Introduction: Dermatology is a specialty, which not only deals with dermatological problems with outpatient but also inpatients referrals. The importances of Dermatologist in hospital setting are rising due to changing condition of medical care. Since no peer-reviewed articles are available for dermatological problems in a neurological set up, we conducted this study to know about pattern of skin disorders in neurological patients. Material and Methods: The present study was a prospective study in a neurological setup, which included data from hospital dermatology consultation request forms over a period of one year. The data included demographic profile of the patient investigation where needed, neurological diagnosis and final dermatological diagnosis. The data was analyzed using SPSS. Results: A total of 285 patients who were requested for consultation were included in the study. Face was the commonest site of involvement (19.6%. Laboratory examination of referred patients revealed abnormal blood counts in 2% cases, renal function tests in 0.7% and urine in 0.4% cases. CT scan showed abnormal findings in 65.6% patients. The most common drug used in these patients was phenytoin (29.1%. The most common dermatological diagnosis was Infection and Infestation (34.7% followed by eczema (46.6%. Drug rash was seen in 3.9% cases. Out of which one had phenytoin induced Steven Johnson syndrome. Skin biopsy was done in 5 patients. Topicals was advised in 80%. Upon discharge 10% of inpatients didn’t require any follow-up. The patients who were followed up after 4 weeks, about 48% had their symptoms resolved with topicals and oral treatment as required. About 38% required more than two follow ups due to chronic course of the diseases. Conclusions: This present study discussed about various manifestations of skin disorders in a neurological set up and emphasizes the role of dermatologist in treating skin problems both in outpatient as well as inpatient

  15. Using phosphate supplementation to reverse hypophosphatemia and phosphate depletion in neurological disease and disturbance. (United States)

    Håglin, Lena


    Hypophosphatemia (HP) with or without intracellular depletion of inorganic phosphate (Pi) and adenosine triphosphate has been associated with central and peripheral nervous system complications and can be observed in various diseases and conditions related to respiratory alkalosis, alcoholism (alcohol withdrawal), diabetic ketoacidosis, malnutrition, obesity, and parenteral and enteral nutrition. In addition, HP may explain serious muscular, neurological, and haematological disorders and may cause peripheral neuropathy with paresthesias and metabolic encephalopathy, resulting in confusion and seizures. The neuropathy may be improved quickly after proper phosphate replacement. Phosphate depletion has been corrected using potassium-phosphate infusion, a treatment that can restore consciousness. In severe ataxia and tetra paresis, complete recovery can occur after adequate replacement of phosphate. Patients with multiple risk factors, often with a chronic disease and severe HP that contribute to phosphate depletion, are at risk for neurologic alterations. To predict both risk and optimal phosphate replenishment requires assessing the nutritional status and risk for re-feeding hypophosphatemia. The strategy for correcting HP depends on the severity of the underlying disease and the goal for re-establishing a phosphate balance to limit the consequences of phosphate depletion.

  16. Computed tomography in Duchenne type muscular dystrophy

    Kawai, Mitsuru; Kunimoto, Masanari; Motoyoshi, Yasufumi; Kuwata, Takashi; Nakano, Imaharu


    The computed tomography (CT) scan was performed on 91 Duchenne type muscular dystrophy (DMD) patients on the following four levels; (1) at the level of L3 vertebra, (2) 2-3cm above the symphysis pubica, (3) midposition of the thigh, (4) largest-diameter section of the lower leg. The CT of muscles common to most of the DMD patients were as follows: 1. Muscle atrophy: Muscle atrophy was shown as a reduction in the cross-sectional area of the muscles. Very mild muscle atrophy could be detected either by the clearly identified muscle border or by scattered low-density areas of so-called ''moth-eaten'' appearance within muscles. 2. Fat infiltration: The decrease in radio-density of muscles was interpreted as infiltration of fatty tissue. This type of density change was further classified into diffuse, streaked, cobblestone and salt-and-pepper patterns according to the spacial distribution of low-density areas. 3. Selectivity pattern: As the chronological sequence of DMD muscle degeneration is usually different among individual muscles, it may be seen, in some stages, that some of the synergistic muscles are still only slightly involved, while the others are quite severely atrophied with evident fat infiltration. In certain stages of the disease, most of the patients show relative preservation of particular muscles although they assumed a rounded shape. The most resistent muscle was musculus gracilis, followed by the musculus sartorius, musculus semitendinosus (and/or musculus semimembranosus) in that order. According to the severity of the CT changes, 86 of the 91 patients were classed into five stages from A1 to A5. Morphological stages (A1-A5) were well correlated to the functional disability stages by Ueda with a correlation factor of r=0.88. (J.P.N.)

  17. Congenital muscular dystrophies--problems of classification. (United States)

    Lenard, H G


    The classification of congenital muscular dystrophies (CMD), based on perceived clinical and morphological similarities or differences, is controversial. CMD without cerebral involvement has sometimes been divided into a mild and a severe form. This distinction is, however, arbitrary and not uncontested. Whether Ullrich's disease, formerly called atonic-sclerotic dystrophy, is a disease entity and if so, whether it is a primary muscle disorder, is uncertain. CMD without cerebral involvement is inherited in an autosomal recessive fashion in the great majority of cases. CMDs with cerebral involvement are usually classified into at least three forms: the Fukuyama type of CMD, occurring almost exclusively in Japanese patients; CMD with hypomyelination, sometimes also called the occidental type of cerebromuscular dystrophy; and Walker-Warburg syndrome. Muscle-eye-brain disease, described in a number of Finnish patients, may or may not belong in this last category. In CMD with cerebral involvement inheritance is also autosomal recessive. It is possible that single sporadic cases are phenocopies due to infectious or other exogenous causes. Reports of clinical and morphological findings from an increasing number of patients show a high degree of variability within and, on the other hand, certain similarities between the forms of CMD with cerebral involvement. In addition, neuroradiological changes are also found with increasing frequency in CMD patients without clinical neuropsychological abnormalities. It is not unreasonable to speculate that molecular genetic techniques will reveal in the near future a variable defect in one gene locus or defects in a few gene loci as the cause of the various clinical forms of CMDs.

    Proton NMR-CT (magnetic field strength 0.1 Tesla, resonant frequency 4.5 MHz) was performed in 10 normal females and 19 Duchenne muscular dystrophy (DMD) carriers. The mean age was 39 ± 12 years for the normal females and 42 ± 6 years for the DMD carriers. In DMD carriers, there were 4 definite, 4 probable, and 11 possible carriers. T 1 (spin-lattice relaxation time) image was obtained for a slice at the buttock, mid-thigh and calf levels respectively. T 1 values were measured for the medial portion of the gluteus maximus, the vastus lateralis of the quadriceps femoris, and the gastrocnemius. The bound water fraction (BWF) was calculated from Fullerton's equation based on the fast proton diffusion model. The following results were obtained: (1) In normal females, muscle T 1 value was highest in the gastrocnemius and lowest in the gluteus maximus. (2) In DMD carriers, T 1 values of the gluteus maximus and quadriceps femoris were significantly higher than those of the normal females. There was, however, no significant difference in T 1 value of the gastrocnemius between DMD carriers and normal females. (3) In DMD carriers, BWFs of the gluteus maximus and quadriceps femoris were significantly lower than those of the normal females. (4) In DMD carriers, no significant correlation was observed between the muscle T 1 values and the serum creatine phosphokinase values. Increased tissue water content in the lower parts of the body due to gravity is considered to be the primary cause of the high T 1 value in the gastrocnemius of normal females. The presence of the degenerating muscle fibers are presumed responsible for the high T 1 value and low BWF in the proximal muscles of DMD carriers. (author)

    Proton NMR-CT (magnetic field strength 0.1 Tesla, resonant frequency 4.5 MHz) was performed in 15 normal (NC) and 20 Duchenne muscular dystrophy (DMD) males. The age ranged from 3 to 47 years for the NC males, and 1 to 14 years for the DMD males. In the DMD group there were one subclinical stage, 4 stage 1, 6 stage 2, 4 stage 3, and 5 stage 5 or higher patients. T 1 (longitudinal relaxation) images were obtained for three slices at the buttock, midthigh, and calf levels. The T 1 values were measured for the medial portion of the gluteus maximus, the vastus lateralis of the quadriceps femoris, the adductors, the sartorius, the gracilis, and the gastrocnemius muscles. Bound water fraction (BWF) was calculated from Fullerton's equation based on the fast diffusion model. The following results were obtained: (1) In the NC group, muscle T 1 values declined gradually with maturation under the age of 10, and became constant beyond that. The average T 1 value was 280 ms for the age group between 3 and 6 years, 270 ms for 7 and 10 years, and 260 ms for those older than 10 years. (2) Muscle BWF increased with maturation in the NC group. (3) In the DMD group, T 1 values were initially higher than normal (300 ms), declined rapidly with the progress of the disease, and reached the same low level as the subcutaneous fat (190 ms). (4) This decrease of T 1 value in DMD was not uniform for all muscles, being most prominent in the gluteus maximus and least so in the sartorius and gracilis. (5) In the early stages of DMD, the BWF was lower than normal. (J.P.N.)

  1. Potential indications for deep brain stimulation in neurological disorders: an evolving field. (United States)

    Budman, E; Deeb, W; Martinez-Ramirez, D; Pilitsis, J G; Peng-Chen, Z; Okun, M S; Ramirez-Zamora, A


    Deep brain stimulation (DBS) is an established therapy for appropriately selected patients with movement disorders and neuropsychiatric conditions. Although the exact mechanisms and biology of DBS are not fully understood, it is a safe and well-tolerated therapy for many refractory cases of neuropsychiatric disease. Increasingly, DBS has been explored in other conditions with encouraging results. In this paper, available data is reviewed and new DBS targets, challenges and future directions in neurological disorders are explored. A detailed search of the medical literature discussing the potential use of DBS for neurological disorders excluding accepted indications was conducted. All reports were analyzed individually for content and redundant articles were excluded by examining individual abstracts. The level of evidence for each indication was summarized. Multiple studies report promising preliminary data regarding the safety and efficacy of DBS for a variety of neurological indications including chronic pain, tinnitus, epilepsy, Tourette syndrome, Huntington's disease, tardive dyskinesia and Alzheimer's disease. The initial results of DBS studies for diverse neurological disorders are encouraging but larger, controlled, prospective, homogeneous clinical trials are necessary to establish long-term safety and effectiveness. The field of neuromodulation continues to evolve and advances in DBS technology, stereotactic techniques, neuroimaging and DBS programming capabilities are shaping the present and future of DBS research and use in practice. © 2017 EAN.

  2. Long-term neurological conditions: management at the interface between neurology, rehabilitation and palliative care. (United States)

    Turner-Stokes, Lynne; Sykes, Nigel; Silber, Eli


    Long-term neurological conditions (LTNCs) comprise a diverse set of conditions resulting from injury or disease of the nervous system that will affect an individual for life. Some 10 million people in the UK are living with a neurological condition which has a significant impact on their lives, and they make up 19% of hospital admissions. These guidelines build on the Quality Requirements in the National Service Framework for Long-term (Neurological) Conditions to explore the interaction between specialist neurology, rehabilitation and palliative care services, and how they may best work together to provide long-term support for people with LTNCs and the family members who care for them. The guidelines also provide some practical advice for other clinicians when caring for someone with an LTNC, and outline indications for specialist referral. This article provides a brief summary. Full details of the methods and literature evaluation, as well as tools for implementation, are available in the full guideline.

    The presence of nonprogressive cognitive impairment is recognized as a common feature in a substantial proportion of patients with Duchenne muscular dystrophy. To investigate the possible role of mutations along the dystrophin gene affecting different brain dystrophin isoforms and specific cognitive profiles, 42 school-age children affected with Duchenne muscular dystrophy, subdivided according to sites of mutations along the dystrophin gene, underwent a battery of tests tapping a wide range of intellectual, linguistic, and neuropsychologic functions. Full-scale intelligence quotient was approximately 1 S.D. below the population average in the whole group of dystrophic children. Patients with Duchenne muscular dystrophy and mutations located in the distal portion of the dystrophin gene (involving the 140-kDa brain protein isoform, called Dp140) were generally more severely affected and expressed different patterns of strengths and impairments, compared with patients with Duchenne muscular dystrophy and mutations located in the proximal portion of the dystrophin gene (not involving Dp140). Patients with Duchenne muscular dystrophy and distal mutations demonstrated specific impairments in visuospatial functions and visual memory (which seemed intact in proximally mutated patients) and greater impairment in syntactic processing.

    Sultan, A.; Fayaz, M.


    Cardiac assessment was not done routinely in Duchenne (DMD) and Becker muscular dystrophy (BMD) patients in Northern region of England while evidence was gathering on progressive cardiomyopathy in these patients. We wanted to find out the prevalence, progression and clinical features of cardiac involvement in Duchenne and Becker muscular dystrophy. Methods: It is a retrospective review of clinical, electrocardiographic and echocardiographic assessments. The notes of 52 Duchenne and Becker muscular dystrophy patients were reviewed out of which 32 had DMD, 6 had Intermediate muscular dystrophy (IMD) and 14 had BMD. Prevalence of preclinical and clinically evident cardiac involvement was 88.4% in DMD and BMD patients. Sixty nine% of patients had clinically evident cardiac involvement but only four patients had cardiac symptoms in the form of palpitations, out of which two were due to respiratory dysfunction and others was due to cardiac failure. Clinical examination of the rest of all of the patients was unremarkable. Electrocardiogram was abnormal in 88.4% of patients. Conduction defects were found in 19.4% of patients. Echocardiogram was abnormal in 80.7% of patients but all were poor echo subjects including those who had normal echocardiogram. Though most patients were asymptomatic, a high percentage had evidence of preclinical and clinically evident cardiac involvement. So in all patients with Xp21 linked muscular dystrophy a routine baseline cardiac assessment should be done at the age of 10 years and reviewed after intervals of one to two years. (author)

CONCLUSION: The presence of a deletion in the SMN gene can help to confirm this diagnosis in unclear presentations.

  7. Trends in American Board of Psychiatry and Neurology specialties and neurologic subspecialties (United States)

    Faulkner, L.R.; Juul, D.; Pascuzzi, R.M.; Aminoff, M.J.; Crumrine, P.K.; DeKosky, S.T.; Jozefowicz, R.F.; Massey, J.M.; Pirzada, N.; Tilton, A.


    Objective: To review the current status and recent trends in the American Board of Psychiatry and Neurology (ABPN) specialties and neurologic subspecialties and discuss the implications of those trends for subspecialty viability. Methods: Data on numbers of residency and fellowship programs and graduates and ABPN certification candidates and diplomates were drawn from several sources, including ABPN records, Web sites of the Accreditation Council for Graduate Medical Education and the American Medical Association, and the annual medical education issues of the Journal of the American Medical Association. Results: About four-fifths of neurology graduates pursue fellowship training. While most recent neurology and child neurology graduates attempt to become certified by the ABPN, many clinical neurophysiologists elect not to do so. There appears to have been little interest in establishing fellowships in neurodevelopmental disabilities. The pass rate for fellowship graduates is equivalent to that for the “grandfathers” in clinical neurophysiology. Lower percentages of clinical neurophysiologists than specialists participate in maintenance of certification, and maintenance of certification pass rates are high. Conclusion: The initial enthusiastic interest in training and certification in some of the ABPN neurologic subspecialties appears to have slowed, and the long-term viability of those subspecialties will depend upon the answers to a number of complicated social, economic, and political questions in the new health care era.

    Directory of Open Access Journals (Sweden)

    Talys J. Pinheiro

    Full Text Available ABSTRACT The epidemics of Chikungunya virus (CHIKV and Zika virus (ZIKV infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular, fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis. The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options.

  10. Music-based interventions in neurological rehabilitation. (United States)

    Sihvonen, Aleksi J; Särkämö, Teppo; Leo, Vera; Tervaniemi, Mari; Altenmüller, Eckart; Soinila, Seppo


    During the past ten years, an increasing number of controlled studies have assessed the potential rehabilitative effects of music-based interventions, such as music listening, singing, or playing an instrument, in several neurological diseases. Although the number of studies and extent of available evidence is greatest in stroke and dementia, there is also evidence for the effects of music-based interventions on supporting cognition, motor function, or emotional wellbeing in people with Parkinson's disease, epilepsy, or multiple sclerosis. Music-based interventions can affect divergent functions such as motor performance, speech, or cognition in these patient groups. However, the psychological effects and neurobiological mechanisms underlying the effects of music interventions are likely to share common neural systems for reward, arousal, affect regulation, learning, and activity-driven plasticity. Although further controlled studies are needed to establish the efficacy of music in neurological recovery, music-based interventions are emerging as promising rehabilitation strategies.

  11. The neurology of aretaeus: radix pedis neurologia. (United States)

    Pearce, J M S


    Aretaeus (Aretaios) was a physician born in Cappadocia in about the 2nd century AD, a student of medicine and physician in Alexandria. His works are found in eight books which espoused the physiological and pathological views of the Hippocratic principles derived from the pneumatists and the eclectic schools. Though he has been called the forgotten physician, it has been said that: 'after Hippocrates no single Greek author has equalled Aretaios'. In order to give an indication of his neurological legacy, this paper offers a summary of and quotations from his principal neurological contributions: migraine, vertigo, tetanus, epilepsy, melancholia, strokes and paralysis. One of his most important discoveries was the notion that the pyramidal tract decussates. Copyright © 2013 S. Karger AG, Basel.

    Martínez-Guzmán, Edgar; Gámez-González, Luisa Berenise; Rivas-Larrauri, Francisco; Sorcia-Ramírez, Giovanni; Yamazaki-Nakashimada, Marco


    Kawasaki disease (KD) is a type of systemic vasculitis of unknown etiology. Atypical Kawasaki disease is defined as that where there are signs and symptoms not corresponding to the classical criteria for this nosological entity. Children with atypical Kawasaki disease may present with acute abdominal symptoms, meningeal irritation, pneumonia or renal failure. We describe 4 children with ages ranging from 2 to 12 years who had atypical Kawasaki disease, with neurological and gastrointestinal symptoms as part of the systemic presentation of the disease. Treatment consisted of immunoglobulin and corticosteroids with good evolution. KD is a systemic vasculitis that can involve many territories. Atypical manifestations can mislead the clinician and delay diagnosis. Pediatricians and sub-specialists should be aware of these neurological manifestations in order to provide adequate and opportune treatment.

  13. Psychiatry and neurology: from dualism to integration. (United States)

    Sobański, Jerzy A; Dudek, Dominika


    The two objectives of the following paper are: to make few remarks on the topic absorbing neurologists, psychiatrists, and neuropsychiatrists - integration and division of their specialties; and to describe the situation in Poland, reflected in the latest literature. The authors describe the former and present processes of approaches and divisions in psychiatry and neurology. They indicate dissemination of mutual methods of structural and action brain neuroimaging, neurophysiology, neurogenetics, and advanced neurophysiology diagnostics. As it seems, even the effectiveness of psychotherapy, has recently been associated with changes in brain in functional and even structural markers. The authors indicate the value of the strive to join the still divided specialties, reflected worldwide in attempts of common education and clinical cooperation of physicians. It can be expected that subsequent years will bring further triumphs of neuropsychiatry - a field that combines psychiatry and neurology.

  14. [Neurological soft signs in early onset schizophrenia]. (United States)

    Bourgou Gaha, S; Halayem Dhouib, S; Amado, I; Bouden, A


    Neurological soft signs (NSS) are subtle neurological abnormalities that cannot be linked to the achievement of a specific region of the central nervous system and which are not part of a particular neurological syndrome. These signs are observed in the case of diseases supporting the neurodevelopmental model such as schizophrenia in general and its early form defined notably by an age of onset of less than 18 years. Indeed, the NSS belong to a set of clinical, cognitive, electrophysiological and neuroanatomical markers reflecting neurodevelopmental brain abnormalities in patients with schizophrenia. The objectives of our study were to determine the prevalence, the scores, and the nature of neurological soft signs (NSS) in adolescent patients suffering from early onset schizophrenia diagnosis in comparison to healthy controls, and to explore the correlations between NSS and the demographic, clinical and therapeutic features of these patients. Twelve adolescents were recruited in the Child Psychiatry Department at the Razi Hospital (Tunisia), with the diagnosis of schizophrenia according to the DSM-IV supplemented by the Kiddie SAD PL. They were matched by age and educational level with twelve healthy controls without psychiatric family or personal history. The clinical status of the patients was assessed using the Positive and Negative Syndrome Scale (PANSS). Neurological soft signs (NSS) were rated with the Neurological Soft Signs Examination (NSSE) by Krebs et al. (2000) for the two groups. This scale is composed of 23 items exploring motor coordination, motor integrative function, sensory integration, involuntary movements and quality of lateralization. The mean age of our population was 14.7 years. The average age of onset of the disease was 12.2 years. The sex-ratio was 1.4. Educational level was 7.4 years. The PANSS mean total score was 74.3. The mean daily dose, in chlorpromazine equivalents, was 523.9 mg/day. Four patients received a strict monotherapy of

    Gupta, Namit B; Khadilkar, Satish V; Bangar, Sachin S; Patil, Tukaram R; Chaudhari, Chetan R


    In the context of inadequacy of neurology workforce in India, it is important to understand factors that post-graduate medical students consider for and against choosing neurology as their career option. Understanding these factors will help in planning strategies to encourage students to pursue a career in neurology. At present, there is a paucity of studies addressing this issue in India. (1) To analyze factors, which post-graduate students consider for and against choosing neurology as a career specialty. (2) To access the level and quality of neurology exposure in the current MBBS and MD curricula. Statewide questionnaire based study was conducted in the state of Maharashtra for students eligible to take DM neurology entrance examination (MD Medicine and MD Pediatrics). In this survey, 243 students were enrolled. Factors bringing students to neurology were - intellectual challenge and logical reasoning (72%), inspired by role model teachers (63%), better quality-of-life (51%) and scope for independent practice without expensive infrastructure (48%). Factors preventing students from taking neurology were - perception that most neurological diseases are degenerative (78%), neurology is mainly an academic specialty (40%), neurophobia (43%) and lack of procedures (57%). Inadequate exposure and resultant lack of self-confidence were common (31%, 70-80%). 84% of the students felt the need for a short term certification course in neurology after MD. To attract more students to neurology, "role model" teachers of neurology could interact and teach students extensively. Neurologists' efforts to shed their diagnostician's image and to shift their focus to therapeutics will help change the image of neurology.

    Directory of Open Access Journals (Sweden)

    Namit B Gupta


    Full Text Available Background: In the context of inadequacy of neurology workforce in India, it is important to understand factors that post-graduate medical students consider for and against choosing neurology as their career option. Understanding these factors will help in planning strategies to encourage students to pursue a career in neurology. At present, there is a paucity of studies addressing this issue in India. Aims and Objectives: (1 To analyze factors, which post-graduate students consider for and against choosing neurology as a career specialty. (2 To access the level and quality of neurology exposure in the current MBBS and MD curricula. Materials and Methods: Statewide questionnaire based study was conducted in the state of Maharashtra for students eligible to take DM neurology entrance examination (MD Medicine and MD Pediatrics. Results: In this survey, 243 students were enrolled. Factors bringing students to neurology were - intellectual challenge and logical reasoning (72%, inspired by role model teachers (63%, better quality-of-life (51% and scope for independent practice without expensive infrastructure (48%. Factors preventing students from taking neurology were - perception that most neurological diseases are degenerative (78%, neurology is mainly an academic specialty (40%, neurophobia (43% and lack of procedures (57%. Inadequate exposure and resultant lack of self-confidence were common (31%, 70-80%. 84% of the students felt the need for a short term certification course in neurology after MD. Conclusions: To attract more students to neurology, "role model" teachers of neurology could interact and teach students extensively. Neurologists′ efforts to shed their diagnostician′s image and to shift their focus to therapeutics will help change the image of neurology. Out-patient neurology clinics should be incorporated early in the student′s career. Procedures attract students; hence, they should be made conversant with procedures and

  17. Spinal muscular atrophy functional composite score: A functional measure in spinal muscular atrophy. (United States)

    Montes, Jacqueline; Glanzman, Allan M; Mazzone, Elena S; Martens, William B; Dunaway, Sally; Pasternak, Amy; Riley, Susan O; Quigley, Janet; Pandya, Shree; De Vivo, Darryl C; Kaufmann, Petra; Chiriboga, Claudia A; Finkel, Richard S; Tennekoon, Gihan I; Darras, Basil T; Pane, Marika; Mercuri, Eugenio; Mcdermott, Michael P


    With clinical trials underway, our objective was to construct a composite score of global function that could discriminate among people with spinal muscular atrophy (SMA). Data were collected from 126 participants with SMA types 2 and 3. Scores from the Hammersmith Functional Motor Scale-Expanded and Upper Limb Module were expressed as a percentage of the maximum score and 6-minute walk test as percent of predicted normal distance. A principal component analysis was performed on the correlation matrix for the 3 percentage scores. The first principal component yielded a composite score with approximately equal weighting of the 3 components and accounted for 82% of the total variability. The SMA functional composite score, an unweighted average of the 3 individual percentage scores, correlated almost perfectly with the first principal component. This combination of measures broadens the spectrum of ability that can be quantified in type 2 and 3 SMA patients. © 2015 Wiley Periodicals, Inc.

  18. Mechanical and muscular factors affecting the efficiency of human movement. (United States)

    Cavanagh, P R; Kram, R


    This paper reviews specific examples of how energy expenditure during submaximal exercise is affected by mechanical and muscular factors. Structural biomechanical variables are discussed as a possible reason for economy differences between individuals. The practical question, "Can economy of performing a certain task be modified?" is posed. Examples of how the manipulation of a particular movement pattern results in an energetic minimum (optimal phenomena) are presented. The physiological mechanisms for these phenomena are summarized. The influence of positive vs negative work and storage of elastic energy in relation to the topic of economy and muscular efficiency is considered. The effects of athletic equipment such as footwear, track surfaces, and bicycle components on economy and muscular efficiency are presented. The prospects for improving athletic performance by improving economy are evaluated, and recommendations for future directions are made.

  1. Are neurology residents interested in headache? (United States)

    Gago-Veiga, A B; Santos-Lasaosa, S; Viguera Romero, J; Pozo-Rosich, P

    The years of residency are the pillars of the subsequent practice in every medical specialty. The aim of our study is to evaluate the current situation, degree of involvement, main interests, and perceived quality of the training received by Spanish residents of neurology, specifically in the area of headache. A self-administered survey was designed by the Headache Study Group of the Spanish Society of Neurology (GECSEN) and was sent via e-mail to all residents who were members of the Society as of May 2015. Fifty-three residents completed the survey (N = 426, 12.4%): 6% were first year residents, 25.5% second year, 23.5% third year, and 45% fourth year residents, all from 13 different Spanish autonomous communities. The areas of greatest interest are, in this order: Vascular neurology, headache, and epilepsy. Of them, 85% believe that the area of headache is undervalued. More than half of residents (52.8%) do not rotate in specific Headache Units and only 35.8% complete their training dominating anaesthetic block and toxin infiltration techniques. Of them, 81.1% believe that research is scarce or absent; 69.8% have never made a poster/presentation, 79.3% have not published and only 15% collaborate on research projects in this area. Lastly, 40% believe that they have not received adequate training. Headache is among the areas that interest our residents the most; however, we believe that we must improve their training both at a patient healthcare level and as researchers. Thus, increasing the number of available courses, creating educational web pages, involving residents in research, and making a rotation in a specialised unit mandatory are among the fundamental objectives of the GECSEN.

  2. Emergency Neurological Life Support: Intracerebral Hemorrhage. (United States)

    Jauch, Edward C; Pineda, Jose A; Hemphill, J Claude


    Intracerebral hemorrhage (ICH) is a subset of stroke due to bleeding within the parenchyma of the brain. It is potentially lethal, and survival depends on ensuring an adequate airway, reversal of coagulopathy, and proper diagnosis. ICH was chosen as an Emergency Neurological Life Support protocol because intervention within the first critical hour may improve outcome, and it is critical to have site-specific protocols to drive care quickly and efficiently.

  3. Music therapy in neurological rehabilitation settings


    Elżbieta Galińska


    The neurologic music therapy is a new scope of music therapy. Its techniques deal with dysfunctions resulting from diseases of the human nervous system. Music can be used as an alternative modality to access functions unavailable through non-musical stimulus. Processes in the brain activated by the influence of music can be generalized and transferred to non-musical functions. Therefore, in clinical practice, the translation of non-musical therapeutic exercises into analogous, isomorphic ...

  4. Complementary and Integrative Medicine for Neurologic Conditions. (United States)

    Wells, Rebecca Erwin; Baute, Vanessa; Wahbeh, Helané


    Although many neurologic conditions are common, cures are rare and conventional treatments are often limited. Many patients, therefore, turn to complementary and alternative medicine (CAM). The use of selected, evidence-based CAM therapies for the prevention and treatment of migraine, carpal tunnel syndrome, and dementia are presented. Evidence is growing many of modalities, including nutrition, exercise, mind-body medicine, supplements, and acupuncture. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. [The problem of suicide in neurologic rehabilitation]. (United States)

    Kallert, T W


    Associations between somatic as well as, in particular, neurological diseases and suicidal acts are outlined, with studies of different diseases having shown that they represent only one factor in motivating the suicidal act. Biographical predispositions and stressful variables from the current social situation are always added. Depressive and organic brain syndromes that can often be found during neurological rehabilitation are discussed in their significance as risk factors for suicidal behavior, also seeking to identify distinct phases of the rehabilitation process afflicted with high suicide risk. An active and carefully directed approach to exploration as well as grasping the psychopathological symptomatology are fundamental elements in the assessment of suicide risk. In this respect, observations of the patient's behaviour and information obtained from relatives are of special importance in neurological rehabilitation clinics. The "presuicidal syndrome" (Ringel) continues to be of high clinical value in assessing the psychodynamics of the individual patient in his development towards the suicidal act. Reflections of suicidal tendencies in countertransference reactions and the communication pathology of suicidal behaviour are more recent aspects that enrich the assessment of suicide risk. Therapeutic management of suicidal patients can firstly be characterized by the principle of specific diagnosis and treatment of the underlying disease; this means that optimum medical care even has a suicide-preventive function. The other principle considers the establishment of a therapeutical relationship as a must, and some critical points in the personal contact with suicidal patients are dealt with in some detail. Especially in neurological rehabilitation clinics, custodial aspects must not be neglected.(ABSTRACT TRUNCATED AT 250 WORDS)

  6. Neurological manifestations of excessive alcohol consumption. (United States)

    Planas-Ballvé, Anna; Grau-López, Laia; Morillas, Rosa María; Planas, Ramón


    This article reviews the different acute and chronic neurological manifestations of excessive alcohol consumption that affect the central or peripheral nervous system. Several mechanisms can be implicated depending on the disorder, ranging from nutritional factors, alcohol-related toxicity, metabolic changes and immune-mediated mechanisms. Recognition and early treatment of these manifestations is essential given their association with high morbidity and significantly increased mortality.

  7. Effects of yoga breathing exercises on pulmonary function in patients with Duchenne muscular dystrophy: an exploratory analysis

    Directory of Open Access Journals (Sweden)

    Marcos Rojo Rodrigues


    Full Text Available OBJECTIVE: Duchenne muscular dystrophy (DMD is the most common form of muscular dystrophy in children, and children with DMD die prematurely because of respiratory failure. We sought to determine the efficacy and safety of yoga breathing exercises, as well as the effects of those exercises on respiratory function, in such children. METHODS: This was a prospective open-label study of patients with a confirmed diagnosis of DMD, recruited from among those followed at the neurology outpatient clinic of a university hospital in the city of São Paulo, Brazil. Participants were taught how to perform hatha yoga breathing exercises and were instructed to perform the exercises three times a day for 10 months. RESULTS: Of the 76 patients who entered the study, 35 dropped out and 15 were unable to perform the breathing exercises, 26 having therefore completed the study (mean age, 9.5 ± 2.3 years; body mass index, 18.2 ± 3.8 kg/m2. The yoga breathing exercises resulted in a significant increase in FVC (% of predicted: 82.3 ± 18.6% at baseline vs. 90.3 ± 22.5% at 10 months later; p = 0.02 and FEV1 (% of predicted: 83.8 ± 16.6% at baseline vs. 90.1 ± 17.4% at 10 months later; p = 0.04. CONCLUSIONS: Yoga breathing exercises can improve pulmonary function in patients with DMD.

  8. Effect of prolonged ischaemic time on muscular atrophy and regenerating nerve fibres in transplantation of the rat hind limb. (United States)

    Tsuji, Naoko; Yamashita, Shuji; Sugawara, Yasushi; Kobayashi, Eiji


    Our aim was to test the influence of cold ischaemia on replanted limbs, focusing on muscular atrophy and neurological recovery. Inbred wild-type and green fluorescent protein (GFP) transgenic (Tg) Lewis rats aged 8-10 weeks were used. The amputated limbs were transplanted at several cold ischaemic times (0, 1, 8, 12, 24, 48, and 72 hours). An arterial ischaemic model and a denervation model were used as controls. To study nerve regeneration, a GFP limb was transplanted on to the syngenic wild Lewis rat. These animals were evaluated histologically, electrophysiologically, and immunohistochemically. The longer the ischaemic time, the more evident was atrophy of the muscles. Electrophysiological investigation showed that the latency at 3 weeks was longer in the transplantation models than in the normal controls, particularly in the longer ischaemia group. Larger numbers of migrating Schwann cells were seen in the group with no delay than in the group that had been preserved for 12 hours. Ischaemia after amputation of a limb causes muscle cells to necrose and atrophy, and these changes worsen in proportion to the ischaemic preservation time. A delay in nerve regeneration and incomplete paralysis caused by malregeneration also affect muscular atrophy.

  9. Lipidomic Evaluation of Feline Neurologic Disease after AAV Gene Therapy

    Directory of Open Access Journals (Sweden)

    Heather L. Gray-Edwards


    Full Text Available GM1 gangliosidosis is a fatal lysosomal disorder, for which there is no effective treatment. Adeno-associated virus (AAV gene therapy in GM1 cats has resulted in a greater than 6-fold increase in lifespan, with many cats remaining alive at >5.7 years of age, with minimal clinical signs. Glycolipids are the principal storage product in GM1 gangliosidosis whose pathogenic mechanism is not completely understood. Targeted lipidomics analysis was performed to better define disease mechanisms and identify markers of disease progression for upcoming clinical trials in humans. 36 sphingolipids and subspecies associated with ganglioside biosynthesis were tested in the cerebrospinal fluid of untreated GM1 cats at a humane endpoint (∼8 months, AAV-treated GM1 cats (∼5 years old, and normal adult controls. In untreated GM1 cats, significant alterations were noted in 16 sphingolipid species, including gangliosides (GM1 and GM3, lactosylceramides, ceramides, sphingomyelins, monohexosylceramides, and sulfatides. Variable degrees of correction in many lipid metabolites reflected the efficacy of AAV gene therapy. Sphingolipid levels were highly predictive of neurologic disease progression, with 11 metabolites having a coefficient of determination (R2 > 0.75. Also, a specific detergent additive significantly increased the recovery of certain lipid species in cerebrospinal fluid samples. This report demonstrates the methodology and utility of targeted lipidomics to examine the pathophysiology of lipid storage disorders.

  10. Time perception distortion in neuropsychiatric and neurological disorders. (United States)

    Teixeira, Silmar; Machado, Sergio; Paes, Flavia; Velasques, Bruna; Silva, Julio Guilherme; Sanfim, Antonio L; Minc, Daniel; Anghinah, Renato; Menegaldo, Luciano L; Salama, Mohamed; Cagy, Mauricio; Nardi, Antonio E; Pöppel, Ernst; Bao, Yan; Szelag, Elzbieta; Ribeiro, Pedro; Arias-Carrión, Oscar


    There is no sense organ specifically dedicated to time perception, as there is for other senses such as hearing and vision. However, this subjective sense of time is fundamental to our conception of reality and it creates the temporal course of events in our lives. Here, we explored neurobiological relations from the clinical perspective, examining timing ability in patients with different neurological and psychiatric conditions (e.g. Parkinson's disease, depression, bipolar disorder, anxiety disorders and schizophrenia). The neural bases of present distortions in time perception and temporal information processing still remain poorly understood. We reviewed: a) how the brain is capable of encoding time in different environments and multiple tasks, b) different models of interval timing, c) brain structures and neurotransmitters associated with time perception, d) the relationship between memory and time perception, e) neural mechanisms underlying different theories in neural and mental processes, and f) the relationship between different mental diseases and time perception. Bibliographic research was conducted based on publications over the past thirteen years written in English in the databases Scielo, Pubmed/MEDLINE, ISI Web of Knowledge. The time perceptions research are executed to evaluate time perception in mental diseases and can provide evidence for future clinical applications.

    Duchenne muscular dystrophy (DMD) and Spinal muscular atrophy (SMA) causes significant disability and progressive functional impairment. Readily available instruments that assess functionality, especially in advanced stages of the disease, are required to monitor the progress of the disease and the impact of therapeutic interventions. To describe the development of a scale to evaluate upper limb function (UL) in patients with DMD and SMA, and describe its validation process, which includes self-training for evaluators. The development of the scale included a review of published scales, an exploratory application of a pilot scale in healthy children and those with DMD, self-training of evaluators in applying the scale using a handbook and video tutorial, and assessment of a group of children with DMD and SMA using the final scale. Reliability was assessed using Cronbach and Kendall concordance and with intra and inter-rater test-retest, and validity with concordance and factorial analysis. A high level of reliability was observed, with high internal consistency (Cronbach α=0.97), and inter-rater (Kendall W=0.96) and intra-rater concordance (r=0.97 to 0.99). The validity was demonstrated by the absence of significant differences between results by different evaluators with an expert evaluator (F=0.023, P>.5), and by the factor analysis that showed that four factors account for 85.44% of total variance. This scale is a reliable and valid tool for assessing UL functionality in children with DMD and SMA. It is also easily implementable due to the possibility of self-training and the use of simple and inexpensive materials. Copyright © 2016 Sociedad Chilena de Pediatría.

    Kurek, Nicholas S.; Chandra, Sathees B.


    Nanotechnology involves probing and manipulating matter at the molecular level. Nanotechnology based molecular diagnostics have the potential to alleviate the suffering caused by many diseases, including neurological disorders, due to the unique properties of nanomaterials. Most neurological illnesses are multifactorial conditions and many of these are also classified as neurobehavioral disorders. Alzheimer's disease, Parkinson's disease, Huntington disease, cerebral ischemia, epilepsy, schizophrenia and autism spectrum disorders like Rett syndrome are some examples of neurological disorders that could be better treated, diagnosed, prevented and possibly cured using nanotechnology. In order to improve the quality of life for disease afflicted people, a wide range of nanomaterials that include gold and silica nanoparticles, quantum dots and DNA along with countless other forms of nanotechnology have been investigated regarding their usefulness in advancing molecular diagnostics. Other small scaled materials like viruses and proteins also have potential for use as molecular diagnostic tools. Information obtained from nanotechnology based diagnostics can be stored and manipulated using bioinformatics software. More advanced nanotechnology based diagnostic procedures for the acquisition of even greater proteomic and genomic knowledge can then be developed along with better ways to fight various diseases. Nanotechnology also has numerous applications besides those related to biotechnology and medicine. In this article, we will discuss and analyze many novel nanotechnology based diagnostic techniques at our disposal today. (author)

  13. Sparring And Neurological Function In Professional Boxers

    Directory of Open Access Journals (Sweden)

    John W Stiller


    Full Text Available AbstractDespite increased interest regarding the potentially long-term negative impact of chronic traumatic brain injury (CTBI, limited research had been conducted regarding such injuries and neurological outcomes in real world settings. To increase understanding regarding the relationship between sparring (e.g., number of years actively training for professional boxing and neurological functioning, professional boxers (n = 237 who competed in Maryland between 2003 to 2008 completed measures regarding sparring exposure (Cumulative Sparring Index; CSI and performance on tests of cognition (Symbol Digit Modalities Test; SDMT and balance (Sharpened Romberg Test; SRT. Measures were completed prior to boxing matches. Higher scores on the CSI (increased sparring exposure were associated with poorer performance on both tests of cognition (SDMT and balance (SRT. A threshold effect was noted regarding performance on the SDMT, with those reporting CSI values greater than about 150 experiencing a decline in cognition. A history of frequent and/or intense sparring may pose a significant risk for developing boxing associated neurological sequelae. Implementing administration of clinically meaningful tests before bouts, such as the CSI, SDMT, and/or the SRT, as well as documentation of results into the boxer’s physicals or medical profiles may be an important step for improving boxing safety.

  14. Neurological Involvement in Behcet’s Disease

    Directory of Open Access Journals (Sweden)

    Gülşen Akman-Demir


    Full Text Available One of the most dreaded organ involvement in Behcet’s disease is neurological involvement. The majority of the cases present with parenchymal CNS involvement characterized as a brainstem meningoencephalitis; a rarer presentation is dural sinus thrombosis. Both situations very rarely occur in the same patient. Since parenchymal neurological involvement in Behcet’s disease is associated with severe sequelae or mortality, it is a poor prognostic organ involvement. In contrast, dural sinus thrombosis in Behcet’s disease has a much better prognosis as compared to the parenchymal involvement, as well as dural sinus thromboses due to other etiologies. There are no randomized controlled treatment trials carried out in neuro-Behcet disease. Mostly accepted approach is to give high dose intravenous steroids at the atack, with a very slow tapering of steroid dose, and adding a long term immunosuppresant. One of the most critical points in neuro-Behcet treatment is not to stop steroids prematurely, and abruptly. It is notable that with the present treatment options, prognosis of neurological involvement in Behcet’s disease is not as grave as it was in the previous years.

  16. [Neurology in mediaeval medical poetry in Latin]. (United States)

    de Frutos-González, V; Guerrero-Peral, A L

    Medical poems written in Latin during the Middle Ages constitute an important part of mediaeval literature on medicine and offer the advantage of making it easier for the reader to memorise their contents. They were to exert a notable influence of later medical literature. An analysis of works such as Medicinalis liber by Benedictus Crispus of Milan; De cultura hortorum by Walahfrid Strabo; the anonymous work known as Macer floridus; De pulsibus, De urinis, and De signis et symptomatibus aegritudinum, three treatises by Aegidius of Corbeil or the Poema anatomicum, belonging to the Salerno Medical School, reveals what neurological aspects were known in the Middle Ages and how important this medical discipline was in that period. References to pathologies in the field of neurology are very frequent in mediaeval medical poems in Latin. They deal with diseases involving the nerves, cephalea, tremors, epilepsy, vertigos and disorders affecting memory or the sense organs. These mediaeval medical works in Latin offer us an interesting insight into the way neurological diseases were viewed by western physicians in the Middle Ages, as well as describing the remedies that were employed at that time to treat them, most of which involved the use of plants that were considered to have medicinal properties.

  17. Human endogenous retroviruses in neurologic disease. (United States)

    Christensen, Tove


    Endogenous retroviruses are pathogenic - in other species than the human. Disease associations for Human Endogenous RetroViruses (HERVs) are emerging, but so far an unequivocal pathogenetic cause-effect relationship has not been established. A role for HERVs has been proposed in neurological and neuropsychiatric diseases as diverse as multiple sclerosis (MS) and schizophrenia (SCZ). Particularly for MS, many aspects of the activation and involvement of specific HERV families (HERV-H/F and HERV-W/MSRV) have been reported, both for cells in the circulation and in the central nervous system. Notably envelope genes and their gene products (Envs) appear strongly associated with the disease. For SCZ, for ALS, and for HIV-associated dementia (HAD), indications are accumulating for involvement of the HERV-K family, and also HERV-H/F and/or HERV-W. Activation is reasonably a prerequisite for causality as most HERV sequences remain quiescent in non-pathological conditions, so the importance of regulatory pathways and epigenetics involved in regulating HERV activation, derepression, and also involvement of retroviral restriction factors, is emerging. HERV-directed antiretrovirals have potential as novel therapeutic paradigms in neurologic disease, particularly in MS. The possible protective or ameliorative effects of antiretroviral therapy in MS are substantiated by reports that treatment of HIV infection may be associated with a significantly decreased risk of MS. Further studies of HERVs, their role in neurologic diseases, and their potential as therapeutic targets are essential. © 2016 APMIS. Published by John Wiley & Sons Ltd.

  18. Residency Training: Work engagement during neurology training. (United States)

    Zis, Panagiotis; Anagnostopoulos, Fotios; Artemiadis, Artemios K


    Work engagement, defined as a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption, can ameliorate patient care and reduce medical errors. The purpose of this cross-sectional study was to investigate work engagement among neurology residents in the region of Attica, Greece. In total, 113 residents participated in this study. Demographic and work-related characteristics, as well as emotional exhaustion and personality traits (neuroticism), were examined via an anonymous questionnaire. Work engagement was measured by the Utrecht Work Engagement Scale. The study sample had a mean age of 34.6 ± 3.6 years, ranging from 26 to 45 years. Sixty-two (54.9%) participants were women and 45 (39.8%) were married. After adjusting for sex, emotional exhaustion, and neuroticism, the main factors associated with work engagement were autonomy and chances for professional development. Providing more chances for trainees' professional development as well as allowing for and supporting greater job autonomy may improve work engagement during neurology training. © 2016 American Academy of Neurology.

  19. Neurological Manifestations In Inflammatory Bowel Disease

    Directory of Open Access Journals (Sweden)

    youssef HNACH


    Full Text Available IntroductionThe purpose of this retrospective study was to report neurological manifestations noted in patients who were monitored for inflammatory bowel disease, in order to document the pathophysiological, clinical, progressive, and therapeutic characteristics of this entity.Material and methodsWe conducted a retrospective study on patients monitored -in the gastroenterology service in Ibn Sina Hospital in Rabat, Morocco- for inflammatory bowel disease from 1992 till 2013 and who developed neurological manifestations during its course. Patients with iatrogenic complications were excluded, as well as patients with cerebrovascular risk factors.ResultsThere were 6 patients, 4 of whom have developed peripheral manifestations. Electromyography enabled the diagnosis to be made and the outcome was favorable with disappearance of clinical manifestations and normalization of the electromyography.The other 2 patients, monitored for Crohn’s disease, developed ischemic stroke. Cerebral computed tomography angiography provided positive and topographic diagnosis. Two patients were admitted to specialized facilities.ConclusionNeurological manifestations in inflammatory bowel disease are rarely reported.  Peripheral neuropathies and stroke remain the most common manifestations. The mechanisms of these manifestations are not clearly defined yet. Currently, we hypothesize the interaction of immune mediators.

  20. [Chronic subdural hematoma and transient neurologic deficits]. (United States)

    Nicoli, F; Milandre, L; Lemarquis, P; Bazan, M; Jau, P


    Three cases of chronic subdural hematoma (CSDH) revealed by transient neurological accidents are reported. Although well-known this condition is rare: 1 to 9 p. 100 of CSDHs. Questioning may bring out a history of cranial injury and headache, even minor ones, which are unusual in transient ischemic accidents (TIA). Transient phenomena, such as motor aphasia or speech interruption, point to the diagnosis, especially in male patients over 60 years of age. The finding at electroencephalography of a delta activity more than 48 hours after a TND should exclude the diagnosis of TIA until a CT scan is performed. Since the causes of neurological deficits regressing within less than 24 hours may be ischemia as well a hemorrhage or tumour, the term of transient neurological accident (TNA) should preferably be used, and an emergency CT scan should be performed for diagnostic and therapeutic purposes. Owing to the possibility of another concomitant cause of TNA, the finding of a subdural haematoma should not deter from pursuing cardiovascular examinations. The mechanism of TNA probably involves a vascular factor, as suggested by I-123 IMP cerebral SPECT which shows an intercritical decrease in cerebral blood flow and/or an epileptic factor.

    Case report with review describes X-linked muscular dystrophy with contractures in 28 years old man and his cousin. The disease revealed itself in an early stage (age 5-10), the process was progressing with apparent tendons retraction and contraction, limited movement in the areas of the neck and back of spine, atrophy of shoulder and pelvic yard and back muscles. Intellect was intact. Cardyomyopathy was exhibited. CK was normal. EMG showed classic myopathic features. Muscle biopsy showed different caliber groups of muscle fibers, growth of endo-perimesial connective tissue. Clinical manifestations together with electrophysiological and histological data suggest consistency with Rotthauwe-Mortier-Bayer X-linked muscular dystrophy.

  11. Congenital contractural arachnodactyly with neurogenic muscular atrophy: case report

    Directory of Open Access Journals (Sweden)

    Scola Rosana Herminia


    Full Text Available We report the case of a 3-1/2-year-old girl with hypotonia, multiple joint contractures, hip luxation, arachnodactyly, adducted thumbs, dolichostenomelia, and abnormal external ears suggesting the diagnosis of congenital contractural arachnodactyly (CCA. The serum muscle enzimes were normal and the needle electromyography showed active and chronic denervation. The muscle biopsy demonstrated active and chronic denervation compatible with spinal muscular atrophy. Analysis of exons 7 and 8 of survival motor neuron gene through polymerase chain reaction did not show deletions. Neurogenic muscular atrophy is a new abnormality associated with CCA, suggesting that CCA is clinically heterogeneous.

  12. The paradox of muscle hypertrophy in muscular dystrophy. (United States)

    Kornegay, Joe N; Childers, Martin K; Bogan, Daniel J; Bogan, Janet R; Nghiem, Peter; Wang, Jiahui; Fan, Zheng; Howard, James F; Schatzberg, Scott J; Dow, Jennifer L; Grange, Robert W; Styner, Martin A; Hoffman, Eric P; Wagner, Kathryn R


    Mutations in the dystrophin gene cause Duchenne and Becker muscular dystrophy in humans and syndromes in mice, dogs, and cats. Affected humans and dogs have progressive disease that leads primarily to muscle atrophy. Mdx mice progress through an initial phase of muscle hypertrophy followed by atrophy. Cats have persistent muscle hypertrophy. Hypertrophy in humans has been attributed to deposition of fat and connective tissue (pseudohypertrophy). Increased muscle mass (true hypertrophy) has been documented in animal models. Muscle hypertrophy can exaggerate postural instability and joint contractures. Deleterious consequences of muscle hypertrophy should be considered when developing treatments for muscular dystrophy. Copyright © 2012 Elsevier Inc. All rights reserved.

  13. Programa de entrenamiento para el incremento de la fuerza muscular


    Mendieta, Lenin; Yaguachi, Fernanda; Toledo, Karla


    Los trabajos de fuerza muscular datan desde el origen del hombre, cuando este por supervivencia tuvo que adaptarse a las diferentes épocas de la historia. La era primitiva, en donde la caza y pesca eran actividades protagónicas de su vida cotidiana, la Grecia clásica en donde el culto por la belleza del cuerpo les llevo a realizar trabajos de fuerza muscular, la era Romana, en donde se echó al traste la formación física y se vicio de orgías de comidas y bailes, la era Renacentista en donde em...

  14. Magnetic resonance imaging of children with Duchenne muscular dystrophy

    International Nuclear Information System (INIS)

    Schreiber, A.; Smith, W.L.; Franken, E.A.; Dunn, V.; Ehrhardt, J.; Ionasescu, V.; Zellweger, H.


    Eight children representing a spectrum of clinical states of biopsy-proven Duchenne muscular dystrophy (DMD) underwent magnetic resonance (MR) scans to assess the degree of muscular involvement and disease progression. Five muscle groups (neck, shoulder girdle, pelvic girdle, thigh and calf) were evaluated. In each case, involved muscles were clearly demarcated. Image estimates of disease severity by degree of muscle involvement correlated well with clinical staging. In our experience MR is useful for assessment of disease stage, selection of appropriate muscles for biopsy and planning for courses of physical and rehabilitation therapy. (orig.)

  15. Progress study of the cardiac damage in Duchenne muscular dystrophy

    Directory of Open Access Journals (Sweden)

    ZHANG Yao


    Full Text Available Duchenne muscular dystrophy (DMD is a fatal muscular disease with rapid progression in children. Most patients die of respiratory and circulatory failure before the age of 20 if there is no systematic treatment. Now the heart problem in this disease has become increasingly prominent, and is thought to be closely associated with certain dystrophin exon deletion. We would like to review the epidemiology, relevance of dystrophin, pathogenesis, clinical manifestations and pathological features, as well as early prevention and treatment of DMD.

[Neuroradiology Department, Kings College Hospital, Denmark Hill, London SE5 9RS (United Kingdom)


    The effects of motor cranial nerve dysfunction on the computed tomography (CT) and magnetic resonance imaging (MRI) appearances of head and neck muscles are reviewed. Patterns of denervation changes are described and illustrated for V, VII, X, XI and XII cranial nerves. Recognition of the range of imaging manifestations, including the temporal changes in muscular appearances and associated muscular grafting or compensatory hypertrophy, will avoid misinterpretation as local disease. It will also prompt the radiologist to search for underlying cranial nerve pathology, which may be clinically occult. The relevant cranial nerve motor division anatomy will be described to enable a focussed search for such a structural abnormality.
