    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.

    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.

    Full Text Available Paraneoplastic neurologic disorders are extremely rare in cancer patients and are most commonly associated with certain tumors, such as ovarian cancer, small cell lung cancer, and breast cancer. We report here a paraneoplastic neurological syndrome in a 53-year-old man with colonic adenocarcinoma with a solitary liver metastasis. His paraneoplastic syndrome was successfully treated by methylprednisolone and primary oncologic therapies including neoadjuvant chemotherapy and definitive surgery. This is also the first documented case of simultaneous manifestation of a sensory neuropathy and limbic encephalitis with colon cancer.

    . Neurological symptoms, such as burning sensations (occasionally accompanied by acroparesthesia) and stroke, are among the first to appear, and occur in both male and female patients. A delay in establishing the diagnosis of Fabry's disease can cause unnecessary problems, especially now that enzyme replacement...... treatment is available to prevent irreversible organ damage. Females with Fabry's disease who present with pain have often been ignored and misdiagnosed because of the disorder's X-linked inheritance. This Review will stress the importance of recognizing neurological symptoms for the diagnosis of Fabry...

    Full Text Available The authors report on six cases of gluten-sensitivity, also defined non-celiac gluten sensitivity, characterized by abdominal features (diarrhea, bloating, pain, genetic positivity for predisposition to celiac disease (DQB1* 02 in all cases; DQA1*05 in three; DQA1*02 in two, DQB1*03 in two, negative anti-t-Transglutaminase antibodies, normal mucosa on biopsy in four cases, type 1 of Marsh in one case. The subjects presented frequent central nervous system (CNS symptoms: headache in three patients, somnolence in one, electroencephalogram aspecific alterations in three (in two of them with previous seizures, leptomeningeal cyst in one, intracranial calcification in one, cerebral gliosis in two. After a gluten-free diet, all intestinal and clinical CNS features remitted, but re-appeared after gluten reintroduction. On the basis of the neurological signs, the authors stress the relevance of immune innate system in the pathogenesis of these cases with possible subsequent evolution on immune adaptive system involvement.

    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.

  8. The Spectrum of Neurological Manifestations Associated with Gaucher Disease

    Full Text Available Gaucher disease, the most common lysosomal storage disorder, is due to a deficiency in the enzyme glucocerebrosidase. This leads to the accumulation of its normal substrate, glucocerebroside, in tissue macrophages, affecting the hematological, visceral, bone and neurologic systems. Gaucher disease is classified into three broad phenotypes based upon the presence or absence of neurological involvement: type 1 (non-neuronopathic, type 2 (acute neuronopathic, and type 3 (subacute neuronopathic. Phenotypically, there is a wide spectrum of visceral and neurological manifestations. Enzyme replacement is effective in managing the visceral disease; however, treating the neurological manifestations has proved to be more challenging. This review discusses the various neurological manifestations encountered in Gaucher disease, and provides a brief overview regarding the treatment and ongoing research challenges.

    2017-12-01

    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.

    Full Text Available Francisco Javier Carod-Artal1,21Neurology Department, Raigmore hospital, Inverness, UK; 2Universitat Internacional de Catalunya (UIC, Barcelona, Spain Abstract: Dengue is the most common mosquito-borne viral infection worldwide. There is increased evidence for dengue virus neurotropism, and neurological manifestations could make part of the clinical picture of dengue virus infection in at least 0.5%–7.4% of symptomatic cases. Neurological complications have been classified into dengue virus encephalopathy, dengue virus encephalitis, immune-mediated syndromes (acute disseminated encephalomyelitis, myelitis, Guillain–Barré syndrome, neuritis brachialis, acute cerebellitis, and others, neuromuscular complications (hypokalemic paralysis, transient benign muscle dysfunction and myositis, and dengue-associated stroke. Common neuro-ophthalmic complications are maculopathy and retinal vasculopathy. Pathogenic mechanisms include systemic complications and metabolic disturbances resulting in encephalopathy, direct effect of the virus provoking encephalitis, and postinfectious immune mechanisms causing immune-mediated syndromes. Dengue viruses should be considered as a cause of neurological disorders in endemic regions. Standardized case definitions for specific neurological complications are still needed.

    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.

    To determine the prevalence, clinical manifestations, and laboratory features of Neuro-Behcets disease. This prospective study was carried out in the Behcets Research Clinic in Shiraz (south-west Iran) and included the patients referred from 1990-1999. The patients' clinical records, images, CSF analyses, and electrodiagnostic studies were reviewed. Eighteen (15 males and 3 females) out of 690 Behcet s patients (2.6%, 95% CI = 1.4-3.8%) were found to have neurological involvement. The mean +/- standard deviation age of these patients was 34.7 +/- 8.6 years. All fulfilled the criteria of the International Study Group of Behcet s Disease. Central nervous system involvement was more common than peripheral nervous system manifestations. Headache, weakness, tingling, and numbness were the most common symptoms. Hyperreflexia, upward plantar reflex, and somatosensory findings were the most frequent signs. Hemispheral and brainstem stroke-like syndromes and cerebral venous thrombosis were the major neurologic presentations. There were also cases of myelitic, pure meningoencephalitic, amyotrophic lateral sclerosis-like, multiple sclerosis-like, and Guillain Barre syndromes. Neuro-Behcets disease must be considered in the differential diagnosis of stroke in young adults, chronic meningitis, intracranial hypertension, multiple sclerosis, myelopathies, and peripheral neuropathies.

    2016-04-01

    Enterovirus 71 frequently involves the central nervous system and may present with a variety of neurologic manifestations. Here, we aimed to describe the clinical features, magnetic resonance imaging (MRI) findings, and cerebrospinal fluid (CSF) profiles of patients presenting with neurologic complications of enterovirus 71 infection. We retrospectively reviewed the records of 31 pediatric patients hospitalized with acute neurologic manifestations accompanied by confirmed enterovirus 71 infection at Ulsan University Hospital between 2010 and 2014. The patients' mean age was 2.9 ± 5.5 years (range, 18 days to 12 years), and 80.6% of patients were less than 4 years old. Based on their clinical features, the patients were classified into 4 clinical groups: brainstem encephalitis (n = 21), meningitis (n = 7), encephalitis (n = 2), and acute flaccid paralysis (n = 1). The common neurologic symptoms included myoclonus (58.1%), lethargy (54.8%), irritability (54.8%), vomiting (48.4%), ataxia (38.7%), and tremor (35.5%). Twenty-five patients underwent an MRI scan; of these, 14 (56.0%) revealed the characteristic increased T2 signal intensity in the posterior region of the brainstem and bilateral cerebellar dentate nuclei. Twenty-six of 30 patients (86.7%) showed CSF pleocytosis. Thirty patients (96.8%) recovered completely without any neurologic deficits; one patient (3.2%) died due to pulmonary hemorrhage and shock. In the present study, brainstem encephalitis was the most common neurologic manifestation of enterovirus 71 infection. The characteristic clinical symptoms such as myoclonus, ataxia, and tremor in conjunction with CSF pleocytosis and brainstem lesions on MR images are pathognomonic for diagnosis of neurologic involvement by enterovirus 71 infection.

    Objective: To determine the incidence, timing, and severity of neurologic findings in acute HIV infection (pre–antibody seroconversion), as well as persistence with combination antiretroviral therapy (cART). Methods: Participants identified with acute HIV were enrolled, underwent structured neurologic evaluations, immediately initiated cART, and were followed with neurologic evaluations at 4 and 12 weeks. Concurrent brain MRIs and both viral and inflammatory markers in plasma and CSF were obtained. Results: Median estimated HIV infection duration was 19 days (range 3–56) at study entry for the 139 participants evaluated. Seventy-three participants (53%) experienced one or more neurologic findings in the 12 weeks after diagnosis, with one developing a fulminant neurologic manifestation (Guillain-Barré syndrome). A total of 245 neurologic findings were noted, reflecting cognitive symptoms (33%), motor findings (34%), and neuropathy (11%). Nearly half of the neurologic findings (n = 121, 49%) occurred at diagnosis, prior to cART initiation, and most of these (n = 110, 90%) remitted concurrent with 1 month on treatment. Only 9% of neurologic findings (n = 22) persisted at 24 weeks on cART. Nearly all neurologic findings (n = 236, 96%) were categorized as mild in severity. No structural neuroimaging abnormalities were observed. Participants with neurologic findings had a higher mean plasma log10 HIV RNA at diagnosis compared to those without neurologic findings (5.9 vs 5.4; p = 0.006). Conclusions: Acute HIV infection is commonly associated with mild neurologic findings that largely remit while on treatment, and may be mediated by direct viral factors. Severe neurologic manifestations are infrequent in treated acute HIV. PMID:27287217

    Full Text Available Objective: To evaluate the neurological complications among Iranian HIV-positive patients. Methods: This cross-sectional study was conducted among 428 patients diagnosed with HIV infection between 2006 and 2009 at Imam Khomeini hospital, Tehran, Iran. Demographic and clinical variables as well as laboratory tests were extracted and analyzed. Also, another 100 patients refereed to Voluntary Counseling and Testing center of the hospital were visited and evaluated for neurological complications. Results: Among the patients, neurologic manifestations were observed in 34 (7.94% patients. Twenty three percent of the patients received antiretroviral therapy. Identified causes included brain toxoplasmosis (14.7%, progressive multi-focal leuko encephalopathy (5.9%, HIV encephalopathy (5.9%, TB meningitis (5% and unknown etiologies (11.8%. Also, among 100 patients who were admitted and visited at the Voluntary Counseling and Testing center, no one was diagnosed for any neurological manifestations. Conclusions: According to our results, toxoplasmosis is the most frequent cause of neurological conditions among Iranian HIV infected patients and should be considered in any HIV/AIDS patient with neurological manifestations.

    Full Text Available BACKGROUND AND AIMS: Snake bite is an important cause of mortality and morbidity in certain parts of Sri Lanka. This study was designed to determine the offending snakes, neurological manifestations, disease course, and outcome in neurotoxic envenomation. METHODS AND MATERIAL: Fifty six consecutive patients admitted with neurological manifestations following snake bite were studied prospectively. Data were obtained regarding the offending snakes, neurological symptoms, time taken for onset of symptoms, neurological signs, and time taken for recovery. RESULTS: The offending snake was Russell′s viper in 27(48.2%, common and Sri Lankan krait in 19(33.9%, cobra in 3(5.4%, and unidentified in 7(12.5%. Ptosis was the commonest neurological manifestation seen in 48(85.7% followed by ophthalmoplegia (75%, limb weakness (26.8%, respiratory failure (17.9%, palatal weakness (10.7%, neck muscle weakness (7.1%, and delayed sensory neuropathy (1.8%. Neurological symptoms were experienced usually within 6 hours after the bite. Following administration of antivenom, the signs of recovery became evident within a few hours to several days. The duration for complete recovery ranged from four hours to two weeks. CONCLUSIONS: Complete recovery of neuromuscular weakness was observed in all patients except for one who died with intracerebral haemorrhage shortly after admission.

    The aim of this study was to assess the incidence, clinical presentation, and outcomes of neurologic disorders secondary to vitamin B deficiencies following bariatric surgery. Patients at a single academic institution who underwent bariatric surgery and developed neurologic complications secondary to low levels of vitamins B1, B2, B6, and B12 between the years 2004 and 2015 were studied. In total, 47 (0.7%) bariatric surgical patients (Roux-en-Y gastric bypass n = 36, sleeve gastrectomy n = 9, and duodenal switch n = 2) developed neurologic manifestations secondary to vitamin B deficiencies. Eleven (23%) patients developed postoperative anatomical complications contributed to poor oral intake. Median duration to onset of neurologic manifestation following surgery was 12 months (IQR, 5-32). Vitamin deficiencies reported in the cohort included B1 (n = 30), B2 (n = 1), B6 (n = 12), and B12 (n = 12) deficiency. The most common manifestations were paresthesia (n = 31), muscle weakness (n = 15), abnormal gait (n = 11), and polyneuropathy (n = 7). Four patients were diagnosed with Wernicke-Korsakoff syndrome (WKS) which was developed after gastric bypass (n = 3) and sleeve gastrectomy (n = 1). Seven patients required readmission for management of severe vitamin B deficiencies. Overall, resolution of neurologic symptoms with nutritional interventions and pharmacotherapy was noted in 40 patients (85%). The WKS was not reversible, and all four patients had residual mild ataxia and nystagmus at the last follow-up time. Nutritional neurologic disorders secondary to vitamin B deficiency are relatively uncommon after bariatric surgery. While neurologic disorders are reversible in most patients (85%) with vitamin replacements, persistent residual neurologic symptoms are common in patients with WKS.

    Today, Lyme disease is the most commonly reported tick-borne disease in the United States and Europe. The culprits behind Lyme disease are the Borrelia species of bacteria. In the USA, Borrelia burgdorferi causes the majority of cases, while in Europe and Asia Borrelia afzelii and Borrelia garinii carry the greatest burden of disease. The clinical manifestations of Lyme disease have been identified as early localized, early disseminated, and late chronic. The neurological effects of Lyme disease include both peripheral and central nervous systems involvement, including focal nerve abnormalities, cranial neuropathies, painful radiculoneuritis, meningitis, and/or toxic metabolic encephalopathy, known as Lyme encephalopathy. Given the geographic predominance of Lyme disease in the Northeast and Midwest of the USA, no major studies have been conducted regarding Southern states. Between 2005 and 2014, the Center for Disease Control has reported 582 confirmed cases of Lyme disease in Texas. Because of the potential for increased incidence and prevalence in Texas, it has become essential for research and clinical efforts to be diverted to the region. The Texas A&M College of Veterinary Medicine and Biomedical Sciences Lyme Lab has been investigating the ecology of Lyme disease in Texas and developing a pan-specific serological test for Lyme diagnosis. This report aimed to exposure materials and raise awareness of Lyme disease to healthcare providers.

    The emergence of influenza A(H1N1) 2009 was met with increased reports of associated neurological manifestations. We aimed to describe neurological manifestations of influenza in adults and children in the United Kingdom that presented at this time. A 2-year surveillance study was undertaken through the British adult and pediatric neurological surveillance units from February 2011. Patients were included if they met clinical case definitions within 1 month of proven influenza infection. Twenty-five cases were identified: 21 (84%) in children and 4 (16%) in adults. Six (29%) children had preexisting neurological disorders. Polymerase chain reaction of respiratory secretions identified influenza A in 21 (81%; 20 of which [95%] were H1N1) and influenza B in 4 (15%). Twelve children had encephalopathy (1 with movement disorder), 8 had encephalitis, and 1 had meningoencephalitis. Two adults had encephalopathy with movement disorder, 1 had encephalitis, and 1 had Guillain-Barré syndrome. Seven individuals (6 children) had specific acute encephalopathy syndromes (4 acute necrotizing encephalopathy, 1 acute infantile encephalopathy predominantly affecting the frontal lobes, 1 hemorrhagic shock and encephalopathy, 1 acute hemorrhagic leukoencephalopathy). Twenty (80%) required intensive care, 17 (68%) had poor outcome, and 4 (16%) died. This surveillance study described a cohort of adults and children with neurological manifestations of influenza. The majority were due to H1N1. More children than adults were identified; many children had specific encephalopathy syndromes with poor outcomes. None had been vaccinated, although 8 (32%) had indications for this. A modified classification system is proposed based on our data and the increasing spectrum of recognized acute encephalopathy syndromes.

    Enterovirus infections in childhood can be associated with significant neurological morbidity. This study aimed to describe the prevalence and range of neurological manifestations, determine the clinical characteristics and assess differences in clinical outcomes for Singaporean children diagnosed with enterovirus infections. In this single-centre, case-control study, clinical data was collected retrospectively from patients admitted to National University Hospital, Singapore, from August 2007 to October 2011 and diagnosed with enterovirus infection, based on the enterovirus polymerase chain reaction test, or cultures from throat and rectal swabs or cerebrospinal fluid samples. The occurrence of neurological manifestations was reviewed and clinical outcomes were assessed. A total of 48 patients (age range: six days-17.8 years) were included in the study. Neurological manifestations were seen in 75.0% of patients, 63.9% of whom presented with aseptic meningitis. Other neurological manifestations included encephalitis, acute cerebellitis, transverse myelitis and autonomic dysfunction. The incidence of neurological manifestations was significantly higher in patients aged > 1 year as compared to younger patients (p = 0.043). In patients without neurological manifestations, a significantly higher proportion presented with hand, foot and mouth disease and poor feeding. Long-term neurological sequelae were seen in 16.7% of patients with neurological manifestations. A wide spectrum of neurological manifestations resulting in a relatively low incidence of long-term neurological sequelae was observed in our study of Singaporean children with enterovirus infections. As some of these neurological morbidities were severe, careful evaluation of children with neurological involvement is therefore necessary. Copyright: © Singapore Medical Association

    We divided 38 patients with cerebrovascular disease of the thalamus into 5 groups according to the site of the thalamic lesions as confirmed by X-ray CT and/or MRI. In 16 patients, we examined the cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO{sub 2}) by positron emission tomography (PET). In the anteromedial thalamic lesion group, patients displayed disturbances of spontaneity, memory, reading and writing. CBF and CMRO{sub 2} were decreased in the frontal, parietal and temporal lobes on the side of the lesion. In the dorsolateral thalamic lesion group, ataxic hemiparesis was a characteristic symptom. CBF and CMRO{sub 2} were decreased in frontoparietal lobes on the side of the lesion. In the group with lesions confined to the nucleus ventralis posterioris thalami, the main symptoms were sensory disturbance, with cheiro-oral sensory syndrome being particularly evident. CBF and CMRO{sub 2} were decreased in the parietal lobe on the side of the lesion. In the group with posterolateral thalamic lesions without pulvinar involvement, patients exhibited thalamic syndrome without thalamic pain. CBF and CMRO{sub 2} were decreased in the frontoparietal and temporal lobes on the side of the lesion. In contrast, in the group with posterolateral thalamic lesions with pulvinar involvement, all patients showed thalamic pain. The decrease in CBF and CMRO{sub 2} extended to the inferomedial region of the temporal lobe in addition to the area of decreased CBF and CMRO{sub 2} observed in the group with posterolateral thalamic lesions without pulvinar involvement. Based on these results, we speculate that the neurological manifestations of thalamic vascular disease are associated with a decrease in cortical CBF and CMRO{sub 2} secondary to the thalamic lesions.

CBF and CMRO 2 were decreased in the frontal, parietal and temporal lobes on the side of the lesion. In the dorsolateral thalamic lesion group, ataxic hemiparesis was a characteristic symptom. CBF and CMRO 2 were decreased in frontoparietal lobes on the side of the lesion. In the group with lesions confined to the nucleus ventralis posterioris thalami, the main symptoms were sensory disturbance, with cheiro-oral sensory syndrome being particularly evident. CBF and CMRO 2 were decreased in the parietal lobe on the side of the lesion. In the group with posterolateral thalamic lesions without pulvinar involvement, patients exhibited thalamic syndrome without thalamic pain. CBF and CMRO 2 were decreased in the frontoparietal and temporal lobes on the side of the lesion. In contrast, in the group with posterolateral thalamic lesions with pulvinar involvement, all patients showed thalamic pain. The decrease in CBF and CMRO 2 extended to the inferomedial region of the temporal lobe in addition to the area of decreased CBF and CMRO 2 observed in the group with posterolateral thalamic lesions without pulvinar involvement. Based on these results, we speculate that the neurological manifestations of thalamic vascular disease are associated with a decrease in cortical CBF and CMRO 2 secondary to the thalamic lesions.

    Full Text Available Background: Leprosy is a chronic granulomatous infectious disease having major burden on humans over thousands of years. If untreated, it results in permanent damage to various systems and organs. So we designed this study to evaluate the neurological complications in early stage in adult leprosy patients. Objective: The aim of this study was to find out the pattern of neurological manifestations among adult leprosy patients. Materials and Methods: This cross-sectional hospital-based study on 85 adult tribal leprosy patients was conducted in a district level health care facility from January to December 2014 using simple, direct, standardized questionnaire including history and neurological examinations. Results: The commonest age group affected was 18–30 years (62.4%. Male group was predominant (68.2%. Majority cases (66% had multibacillary leprosy. At first visit 72.7% cases with neurological findings could not be diagnosed correctly by primary health care personnel. More than six months were required for correct diagnosis in 61.2% cases. Numbness was the commonest (74.5% neurological symptom. In upper limb, motor findings were predominant with wasting in 50.9% cases. In lower limb, sensory findings were predominant with stock pattern sensory impairment being the commonest (56.4%. Ulnar nerve was the commonest peripheral nerve to enlarge with tenderness. Facial nerve was the commonest cranial nerve involved. All cases with multiple cranial nerves involvement were of multibacillary type. Due to physical disability 92.7% cases lost their jobs. Conclusion: In this study neurological involvement was found associated with severe disability.

    2017-01-01

    Full Text Available Magnesium is the second most common intracellular cation and serves as an important metabolic cofactor to over 300 enzymatic reactions throughout the human body. Among its various roles, magnesium modulates calcium entry and release from sarcoplasmic reticulum and regulates ATP pumps in myocytes and neurons, thereby regulating cardiac and neuronal excitability. Therefore, deficiency of this essential mineral may result in serious cardiovascular and neurologic derangements. In this case, we present the clinical course of a 76-year-old woman who presented with marked cardiac and neurological signs and symptoms which developed as a result of severe hypomagnesemia. The patient promptly responded to magnesium replacement once the diagnosis was established. We herein discuss the clinical presentation, pathophysiology, diagnosis, and management of severe hypomagnesemia and emphasize the implications of magnesium deficiency in the cardiovascular and central nervous systems. Furthermore, this case highlights the importance of having high vigilance for hypomagnesemia in the appropriate clinical setting.

    Changes in the clinical presentation of functional disorders and the influence of social and cultural factors can be investigated through the historical case notes from mental hospitals. World War I (WWI) was a potent trigger of functional disorders with neurological or psychiatric symptoms. We analysed 100 randomly selected case files of German servicemen admitted to the Department of Psychiatry of the Charité Medical School of Berlin University during WWI and classified them according to contemporaneous and retrospective modern diagnoses. We compared the clinical presentations with accounts in the German and British medical literature of the time. Most patients obtained the contemporaneous diagnosis of 'psychopathic constitution' or hysteria reflecting the general view of German psychiatrists that not the war but an individual predisposition was the basis for the development of symptoms. The clinical picture was dominated by pseudoneurological motor or sensory symptoms as well as pseudoseizures. Some soldiers relived combat experiences in dream-like dissociative states that partly resemble modern-day post-traumatic stress disorder. Most servicemen were classified as unfit for military service but very few of them were granted compensation. Severe functional disorders of a neurological character could develop even without traumatic exposure in combat, which is of interest for the current debate on triggers of stress disorders. The high incidence of pseudoseizures accords with the psychiatric literature of the time and contrasts with accounts of war-related disorders in Britain. The tendency of German psychiatrists not to send traumatised servicemen back to active duty also distinguished between German and British practice. Our data contribute to the debate on the changing patterns of human responses to traumatic experience and their historical and social context.

    Aim: To assess anti-neuronal antibodies (NA) prevalence and their correlation with neurological disorders and bowel habits in celiac disease (CD) patients. Background: Neurological manifestations are estimated to occur in about 10% of celiac disease patients and NA to central nervous system (CNS) and enteric nervous system (ENS) are found in a significant proportion of them. Little is known about the clinical and immunological features in CD patients with neurological manifestations. Patients and methods: NA to CNS and ENS were investigated in 106 CD patients and in 60 controls with autoimmune disorders by indirect immunofluorescence on rat / primate cerebellar cortex and intestinal (small and large bowel) sections. Results: IgG NA to CNS (titer 1:50 - 1:400) were positive in 23 celiacs (21%), being more frequently detected in those with neurological disorders that in those without neurological dysfunction (49% vs. 8%, P 1:200 had severe constipation. Only one patient with cerebellar ataxia and intestinal sub-occlusion was positive for NA to CNS and ENS. NA to CNS and ENS were found in 7% and 5% of controls, respectively. Conclusion: In CD the positivity of NA to CNS can be regarded as a marker of neurological manifestations. High titer NA to ENS are associated with severe constipation. The demonstration of NA to CNS and ENS suggests an immune-mediated pathogenesis leading to central neural impairment as well as gut dysfunction (hence constipation), respectively. PMID:25926940

  17. Revisiting the Molecular Mechanism of Neurological Manifestations in Antiphospholipid Syndrome: Beyond Vascular Damage

    2014-01-01

    Antiphospholipid syndrome (APS) is a multiorgan disease often affecting the central nervous system (CNS). Typically, neurological manifestations of APS include thrombosis of cerebral vessels leading to stroke and requiring prompt initiation of treatment with antiplatelet drugs or anticoagulant therapy. In these cases, alterations of the coagulation system at various levels caused by multiple effects of antiphospholipid antibodies (aPL) have been postulated to explain the vascular damage to the CNS in APS. However, several nonvascular neurological manifestations of APS have progressively emerged over the past years. Nonthrombotic, immune-mediated mechanisms altering physiological basal ganglia function have been recently suggested to play a central role in the pathogenesis of these manifestations that include, among others, movement disorders such as chorea and behavioral and cognitive alterations. Similar clinical manifestations have been described in other autoimmune CNS diseases such as anti-NMDAR and anti-VGCK encephalitis, suggesting that the spectrum of immune-mediated basal ganglia disorders is expanding, possibly sharing some pathophysiological mechanisms. In this review, we will focus on thrombotic and nonthrombotic neurological manifestations of APS with particular attention to immune-mediated actions of aPL on the vascular system and the basal ganglia.

    Antiphospholipid antibody is associated with a clinical syndrome of vascular thrombosis, thrombocytopenia, recurrent fetal loss and livedo reticularis, whether or not a clinical diagnosis of systemic lupus erythematosus (SLE) coexists. Central nervous system involvement in SLE is multifactorial, thrombotic events, antineuronal antibodies, hypertension, infection, side effects of drugs etc. Antiphospholipid antibodies may play a role in focal neurological manifestations in SLE. In the absence of SLE, different neurological symptoms are well associated with antiphospholipid antibodies including stroke, seizures, dementia, migraine, ocular ischemia, chorea, transverse myelopathy, cerebral phlebitis. Other association are more controversal like Guillain Barré syndrome, motor neuron disease, communicating hydrocephalus. In all patients with antiphospholipid antibodies with neurological involvement, cerebral MRI may be performed with an echocardiographic study because a possible association with Libman and Sacks endocarditis, valve dysfunction or cardiac thrombus source of cerebral ischemia.

    2011-03-01

    Full Text Available Background: World Health Organization declared pandemic phase of human infection with novel influenza A (H1N1 in April 2009. There are very few reports about the neurological complications of H1N1 virus infection in the literature. Occasionally, these complications are severe and even fatal in some individuals. The aims of this study were to report neurological complaints and/or complications associated with H1N1 virus infection. Methods: The medical files of all patients with H1N1 influenza infection admitted to a specified hospital in the city of Shiraz, Iran from October through November 2009 were reviewed. More information about the patients were obtained by phone calls to the patients or their care givers. All patients had confirmed H1N1 virus infection with real-time PCR assay. Results: Fifty-five patients with H1N1 infection were studied. Twenty-three patients had neurological signs and/or symptoms. Mild neurological complaints may be reported in up to 42% of patients infected by H1N1 virus. Severe neurological complications occurred in 9% of the patients. The most common neurological manifestations were headache, numbness and paresthesia, drowsiness and coma. One patient had a Guillain-Barre syndrome-like illness, and died in a few days. Another patient had focal status epilepticus and encephalopathy. Conclusions: The H1N1 infection seems to have been quite mild with a self-limited course in much of the world, yet there appears to be a subset, which is severely affected. We recommend performing diagnostic tests for H1N1influenza virus in all patients with respiratory illness and neurological signs/symptoms. We also recommend initiating treatment with appropriate antiviral drugs as soon as possible in those with any significant neurological presentation accompanied with respiratory illness and flu-like symptoms

    2014-01-01

    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 Celiac disease (CD is an immune-mediated enteropathy and is a rare disease in Asia, including in Korea. However, the ingestion of wheat products, which can act as a precipitating factor of CD, has increased rapidly. CD is a common cause of malabsorption, but many patients can present with various atypical manifestations as first presented symptoms, including anemia, osteopenia, infertility, and neurological symptoms. Thus, making a diagnosis is challenging. We report a case of CD that mimicked amyotrophic lateral sclerosis (ALS. The patient was a sexagenary man with a history of progressive motor weakness for 2 years. He was highly suspected as having ALS. During evaluation of his neurological symptoms, esophagogastroduodenoscopy (EGD was performed because he had experienced loose stools and weight loss for the previous 7 months. On EGD, the duodenal mucosa appeared smooth. A biopsy revealed severe lymphoplasma cell infiltration with flattened villi. His serum endomysial antibody (immunoglobulin A titer was 1:160 (reference, <1:40. Finally, he was diagnosed as having CD, and a gluten-free diet was immediately begun. At a 4-month follow-up, his weight and the quality of his stool had improved gradually, and the neurological manifestations had not progressed.

    Full Text Available Mutations in the m.13094T>C MT-ND5 gene have been previously described in three cases of Leigh Syndrome (LS. In this retrospective, international cohort study we identified 20 clinically affected individuals (13 families and four asymptomatic carriers. Ten patients were deceased at the time of analysis (median age of death was 10 years (range: 5·4 months−37 years, IQR = 17·9 years. Nine patients manifested with LS, one with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS, and one with Leber hereditary optic neuropathy. The remaining nine patients presented with either overlapping syndromes or isolated neurological symptoms. Mitochondrial respiratory chain activity analysis was normal in five out of ten muscle biopsies. We confirmed maternal inheritance in six families, and demonstrated marked variability in tissue segregation, and phenotypic expression at relatively low blood mutant loads. Neuropathological studies of two patients manifesting with LS/MELAS showed prominent capillary proliferation, microvacuolation and severe neuronal cell loss in the brainstem and cerebellum, with conspicuous absence of basal ganglia involvement. These findings suggest that whole mtDNA genome sequencing should be considered in patients with suspected mitochondrial disease presenting with complex neurological manifestations, which would identify over 300 known pathogenic variants including the m.13094T>C.

    Adult-onset adrenoleukodystrophy is a rare x-linked inborn error of metabolism occurring predominantly in males with onset in early 30s. Here, we report a 34-year-old male with first signs of disease in early 20s manifesting as a pure psychiatric disorder. Prior to onset of neurological symptoms, this patient demonstrated a schizophrenia and bipolar-like presentation. The disease progressed over the next 10-13 years and his memory and motor problems became evident around the age of 33 years. Subsequently, diagnostic testing showed the typical magnetic resonance imaging and lab findings for adult-onset adrenoleukodystrophy. This case highlights adult-onset adrenoleukodystrophy which may present as a pure psychiatric disturbance in early adulthood and briefly discusses the prolonged time between the onset of psychiatric symptoms and the onset of neurological disease.

    We examined 500 patients with neurological manifestations of cervical osteochondrosis. It was found that each method of osteochondrosis visualization has its designation. Complex radial visualization of the cervical spine increases the quality of diagnosis: gives the chance to evaluate more precisely expressiveness of its degenerate-dystrophic changes, to establish their importance at medical planning of rehabilitation actions, and also to predict neurological complications. Distribution of patients on clinic-rehabilitation groups allows developing of an effective rehabilitation system of sick and disabled with neurological manifestations of cervical spine osteochondrosis that would not only improve the health of affected, but also have significant socio-economic effect.

    We performed clinical and epidemiological study of 1508 residents living in the southern Altai Mountains and belonging to two subethnic groups (Telengite and Altai Kizhi). The incidence of neurological manifestations of vertebral osteochondrosis in people older than 17 years was 627.6 26.4%. The results show that genetic factors (hereditary polygenic predisposition) play a major role in the development of neurological manifestations of vertebral osteochondrosis. Premorbid state of the organism and diseases of various organs and systems promote the development of this neurological disorder.

    Full Text Available Lyme disease (LD is a tick-borne illness caused by Borrelia burgdorferi sensu stricto. An 80-year-old female from Pennsylvania, USA, presented to an outside hospital with fever, confusion, lower extremity weakness, and stool incontinence. CT head and MRI spine were unremarkable. An infectious work-up including lumbar puncture was negative. She was transferred to our tertiary care hospital. Patient was noted to have mild unilateral right-sided facial droop and a diffuse macular rash throughout the body. She denied any outdoor activities, tick bites, or previous rash. Intravenous ceftriaxone was started for suspected LD. The patient’s symptoms including facial droop resolved within 24 hours of antibiotic therapy. Polymerase chain reaction of the blood, IgM ELISA, and IgM Western blot testing for LD came back positive a few days after initiation of therapy. She was treated for a total of 21 days for neurological LD with complete symptom resolution. Not all patients have the classic “targetoid” EM rash on initial presentation, rash could develop after neurological manifestations, and prompt initiation of antibiotics without awaiting serology is paramount to making a quick and a full recovery. There should be a high index of suspicion for early disseminated LD, as presentations can be atypical.

    2013-01-01

    Isolated vitamin B12 deficiency is a common condition in elderly patients but uncommon in patients younger than 30 years, with an average age of onset between 60 and 70 years. This is because the dietary cobalamin, which is normally split by enzymes in meat in the presence of hydrochloric acid and pepsin in the stomach, is not released in the stomachs of elderly patients, usually due to achlorhydria. Although the body may be unable to release cobalamin it does retain the ability to absorb vitamin B12 in its crystalline form, which is present in multivitamin preparations. Other causes are due to drugs that suppress gastric acid production. Neurological signs of vitamin B12 deficiency can occur in patients with a normal haematocrit and red cell indices. They include paresthesia, loss of sensation and strength in the limbs, and ataxia. Reflexes may be slowed down or increased. Romberg and Babinsky signs may be positive, and vibration and position sensitivity often decreases. Behavoural disorders range from irritability and memory loss to severe dementia. The symptoms often do not fully respond to treatment. A case is presented of an isolated vitamin B12 deficiency in 27 year-old female patient who was seen in primary health care. During anamnesis she mentioned low back pain, to which she attributed the loss of strength and tenderness in the right side of the body, as well as the slow and progressive onset of accompanied headache for the previous 4 days.

    From late 2016 through August 2017, US government personnel serving on diplomatic assignment in Havana, Cuba, reported neurological symptoms associated with exposure to auditory and sensory phenomena. To describe the neurological manifestations that followed exposure to an unknown energy source associated with auditory and sensory phenomena. Preliminary results from a retrospective case series of US government personnel in Havana, Cuba. Following reported exposure to auditory and sensory phenomena in their homes or hotel rooms, the individuals reported a similar constellation of neurological symptoms resembling brain injury. These individuals were referred to an academic brain injury center for multidisciplinary evaluation and treatment. Report of experiencing audible and sensory phenomena emanating from a distinct direction (directional phenomena) associated with an undetermined source, while serving on US government assignments in Havana, Cuba, since 2016. Descriptions of the exposures and symptoms were obtained from medical record review of multidisciplinary clinical interviews and examinations. Additional objective assessments included clinical tests of vestibular (dynamic and static balance, vestibulo-ocular reflex testing, caloric testing), oculomotor (measurement of convergence, saccadic, and smooth pursuit eye movements), cognitive (comprehensive neuropsychological battery), and audiometric (pure tone and speech audiometry) functioning. Neuroimaging was also obtained. Of 24 individuals with suspected exposure identified by the US Department of State, 21 completed multidisciplinary evaluation an average of 203 days after exposure. Persistent symptoms (>3 months after exposure) were reported by these individuals including cognitive (n = 17, 81%), balance (n = 15, 71%), visual (n = 18, 86%), and auditory (n = 15, 68%) dysfunction, sleep impairment (n = 18, 86%), and headaches (n = 16, 76%).

    2016-05-01

    B vitamin deficiency is a leading cause of neurological impairment and disability throughout the world. Multiple B vitamin deficiencies often coexist, and thus an understanding of the complex relationships between the different biochemical pathways regulated in the brain by these vitamins may facilitate prompter diagnosis and improved treatment. Particular populations at risk for multiple B vitamin deficiencies include the elderly, people with alcoholism, patients with heart failure, patients with recent obesity surgery, and vegetarians/vegans. Recently, new clinical settings that predispose individuals to B vitamin deficiency have been highlighted. Moreover, other data indicate a possible pathogenetic role of subclinical chronic B vitamin deficiency in neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. In light of these findings, this review examines the clinical manifestations of B vitamin deficiency and the effect of B vitamin deficiency on the adult nervous system. The interrelationships of multiple B vitamin deficiencies are emphasized, along with the clinical phenotypes related to B vitamin deficiencies. Recent advances in the clinical determinants and diagnostic clues of B vitamin deficiency, as well as the suggested therapies for B vitamin disorders, are described. © The Author(s) 2016.

    Neurological involvement in Behçet's disease is rare, especially at the onset. It can present in the form of parenchymal changes or as damage to the vascular structures in its nonparenchymal form. The coexistence of both kinds of manifestations in the same patient is exceptional. We report the case of a 32-year-old patient with a history of deep venous thrombosis, who was being treated for holocranial headache, apathy, and oral and genital ulcers. Brain magnetic resonance imaging showed hyperintense lesions in the basal ganglia and white matter, and the vascular study evidenced venous thrombosis of the left transverse sinus. After confirming the diagnosis of Behçet's disease with parenchymal and nonparenchymal cerebral involvement, immunosuppressive and corticosteroid therapy was started, resulting in the remission of the symptoms.

Magnetic resonance imaging (MRI) is an appropriate method for evaluating CNS involvement in these patients. Clinical manifestations and MRI findings of CNS lupus should be differentiated from other mimicking diseases such as multiple sclerosis (MS). The aim of this study was to evaluate the prevalence and extent of brain and cervical cord MRI lesions of lupus patients. The relationship between neurological signs and symptoms and MRI findings were evaluated as well. Fifty SLE patients who had been referred to the rheumatology clinic of our hospital within 2009 were included in a cross sectional study. All patients fulfilled the revised 1981 American College of Rheumatology (ACR) criteria for SLE. We evaluated the neurological signs and symptoms and brain and cervical MRI findings in these patients. Forty-one patients (82%) were female and nine (18%) were male. The mean age was 30.1 ± 9.3 years. Twenty eight (56%) patients had an abnormal brain MRI. No one showed any abnormality in the cervical MRI. The lesions in 20 patients were similar to demyelinative plaques. Seventeen patients with abnormal brain MRI were neurologically asymptomatic. There was only a significant relationship between neurological motor manifestations and brain MRI abnormal findings. Unlike the brain, cervical MRI abnormality and especially asymptomatic cord involvement in MRI is quite rare in SLE patients. This finding may be helpful to differentiate SLE from other CNS disorders such as MS

    The bacterium Salmonella enterica serovar Typhi causes typhoid fever, which is typically associated with fever and abdominal pain. An outbreak of typhoid fever in Malawi-Mozambique in 2009 was notable for a high proportion of neurologic illness. Describe neurologic features complicating typhoid fever during an outbreak in Malawi-Mozambique Persons meeting a clinical case definition were identified through surveillance, with laboratory confirmation of typhoid by antibody testing or blood/stool culture. We gathered demographic and clinical information, examined patients, and evaluated a subset of patients 11 months after onset. A sample of persons with and without neurologic signs was tested for vitamin B6 and B12 levels and urinary thiocyanate. Between March - November 2009, 303 cases of typhoid fever were identified. Forty (13%) persons had objective neurologic findings, including 14 confirmed by culture/serology; 27 (68%) were hospitalized, and 5 (13%) died. Seventeen (43%) had a constellation of upper motor neuron findings, including hyperreflexia, spasticity, or sustained ankle clonus. Other neurologic features included ataxia (22, 55%), parkinsonism (8, 20%), and tremors (4, 10%). Brain MRI of 3 (ages 5, 7, and 18 years) demonstrated cerebral atrophy but no other abnormalities. Of 13 patients re-evaluated 11 months later, 11 recovered completely, and 2 had persistent hyperreflexia and ataxia. Vitamin B6 levels were markedly low in typhoid fever patients both with and without neurologic signs. Neurologic signs may complicate typhoid fever, and the diagnosis should be considered in persons with acute febrile neurologic illness in endemic areas.

    Full Text Available Abstract Objective: To describe the spectrum of magnetic resonance imaging (MRI findings in patients with neurological manifestations of dengue. Materials and Methods: We included nine patients with dengue fever (three females and six males; age range, 9–30 years, all of whom presented with neurological manifestations. The MRI examinations, performed in 1.5 T or 3 T scanners, included T1-weighted, T2-weighted, and fluid-attenuated inversion recovery (FLAIR sequences. Diffusion-weighted imaging with apparent diffusion coefficient mapping was also employed. Fast low-angle shot and susceptibility-weighted gradient-recalled echo sequences, as well as contrast-enhanced T1-weighted scans, were also obtained in order to assess parenchymal enhancement. MRI scans were analyzed for lesion distribution and imaging features. Results: All patients showed areas of altered signal intensity that appeared as hyperintensity on T2-weighted and FLAIR sequences. The most commonly affected site was the basal ganglia-thalamus complex. Other affected sites were the cerebellum, cerebral cortex, white matter, and brainstem. In all cases, we observed patchy areas of restricted diffusion and focal areas of hemorrhage. Conclusion: Dengue encephalitis commonly affects the basal ganglia, thalamus, cerebellum, cerebral cortex, and white matter. Therefore, MRI should be an indispensable part of the evaluation of patients with neurological complications of dengue fever.

    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.

    2011-06-01

    Full Text Available Abstract Four dogs with acute neurological signs caused by haemorrhages in the central nervous system were diagnosed with Angiostrongylus vasorum infection as the underlying aetiology. Two dogs presented with brain lesions, one dog with spinal cord lesions and one with lesions in both the brain and spinal cord. Only one dog presented with concurrent signs of classical pulmonary angiostrongylosis (respiratory distress, cough, and only two dogs displayed overt clinical signs of haemorrhages. Results of coagulation assays were inconsistent. Neurological signs reflected the site of pathology and included seizures, various cranial nerve deficits, vestibular signs, proprioceptive deficits, ataxia and paraplegia. One dog died and three were euthanised due to lack of improvement despite medical treatment. This emphasises canine angiostrongylosis as a potential cause of fatal lesions of the central nervous system and the importance of including A. vasorum as a differential diagnosis in young dogs with acute neurological signs in Denmark.

    Tolkachjov, Stanislav N; Wetter, David A

    2017-06-01

    Schnitzler syndrome (SS) is an autoinflammatory dermatosis that often goes undiagnosed for 5-6 years. Patients typically carry a diagnosis of urticaria; however, their cutaneous symptoms fail to respond to typical urticaria therapies and lack symptoms such as pruritus. Additionally, patients with SS may see multiple providers for nonspecific complaints of fever, lymphadenopathy, arthralgias, and bone pain. A correct diagnosis is paramount, as close to 20% of patients may develop a lymphoproliferative disorder and appropriate treatment may ameliorate all symptoms.1 We report 2 cases of SS misdiagnosed as urticaria for years in order to illuminate diagnostic pearls, histopathological findings, and treatment modalities. Additionally, we highlight the importance of neurologic disturbances in this rare but important differential diagnosis of urticaria. J Drugs Dermatol. 2017;16(6):625-627..

    Anton Orlin

    Full Text Available BACKGROUND: Late infantile neuronal ceroid lipofuscinosis (LINCL, one form of Batten's disease is a progressive neurodegenerative disorder resulting from a CLN2 gene mutation. The spectrum of ophthalmic manifestations of LINCL and the relationship with neurological function has not been previously described. METHODS: Patients underwent ophthalmic evaluations, including anterior segment and dilated exams, optical coherence tomography, fluorescein and indocyanine green angiography. Patients were also assessed with the LINCL Neurological Severity Scale. Ophthalmic findings were categorized into one of five severity scores, and the association of the extent of ocular disease with neurological function was assessed. RESULTS: Fifty eyes of 25 patients were included. The mean age at the time of exam was 4.9 years (range 2.5 to 8.1. The mean ophthalmic severity score was 2.6 (range 1 to 5. The mean neurological severity score was 6.1 (range 2 to 11. Significantly more severe ophthalmic manifestations were observed among older patients (p<0.005 and patients with more severe neurological findings (p<0.03. A direct correlation was found between the Ophthalmic Severity Scale and the Weill Cornell Neurological Scale (p<0.002. A direct association was also found between age and the ophthalmic manifestations (p<0.0002, with older children having more severe ophthalmic manifestations. CONCLUSIONS: Ophthalmic manifestations of LINCL correlate closely with the degree of neurological function and the age of the patient. The newly established LINCL Ophthalmic Scale may serve as an objective marker of LINCL severity and disease progression, and may be valuable in the evaluation of novel therapeutic strategies for LINCL, including gene therapy.

    Hypereosinophilic syndrome is characterized by persistent hypereosinophilia and signs or symptoms due to organ involvement, specially nervous system, heart and skin. It can be primary or secondary to allergies, parasites or cancer. Toxocariasis is an uncommon parasitic disease in adults. There is a variant, called visceral larva migrans, that can involve different organs, and among those, the central nervous system. We report a 61 years old male, with a cerebrovascular disease. There were focalizing symptoms, the CAT scan showed multiple ischemic lesions and a peripheral eosinophilia of 12,152 cells/mm3 was present. Anti toxocara IgG antibody titers were 1/1000. The patient was treated with albendazole for 14 days. After a 2 years follow up the patients is in good conditions and, for the first time, his eosinophil count is within normal limits.

    Full Text Available Several genetic disorders caused by defective nucleotide excision repair that affect the skin and the nervous system have been described, including Xeroderma Pigmentosum (XP, De Sanctis–Cacchione syndrome (DSC, Cockayne syndrome, and Trichothiodystrophy. Cutaneous photosensitivity with an increased risk of skin malignancy is a common feature of these disorders, but clinical manifestations commonly overlap these syndromes. Several genes have been found to be altered in these pathologies, but we lack more genotype-phenotype correlations in order to make an accurate diagnosis. Very few cases of DSC syndrome have been reported in the literature. We present a case of a 12-year-old Colombian male, with multiple skin lesions in sun-exposed areas from the age of 3 months and a history of 15 skin cancers. He also displayed severe neurologic abnormalities (intellectual disability, ataxia, altered speech, and hyperreflexia, short stature, and microcephaly, which are features associated with DSC. Genetic testing revealed a novel germline mutation in the XP-C gene (c.547A>T. This is the first case of an XP-C mutation causing De Sanctis–Cacchione syndrome. Multigene panel testing is becoming more widely available and accessible in the clinical setting and will help rapidly unveil the molecular etiology of these rare genetic disorders.

    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.

    Full Text Available Introduction: Vascularity of kidneys is very high, so these organs are potentially susceptible to be affected with toxins including snake venom. Hypersensitivity to snake venous could cause some neurological problem. Case Report: We present a 14-year-old boy with acute kidney injury (AKI due to snake bite. After a few days, kidney failure with hematuria was developed. His serum creatinine level rose to 3 mg/dl and following 2 weeks gradually and decreased to normal level without any special treatment except for anti-venom, which was not prescribed inappropriate time (this type of AKI is not reported previously. He had seizure attacks, which were according to magnetic resonance imaging due to posterior reversible encephalopathy syndrome (PRES (This neurologic complication has been seen in other kidney injuries but up to now it was not reported in snake bite victims. Conclusion: Sanke venom could cause PRES due to AKI and seizure could be one of the most important complications in snake bite.

    1995-09-01

    Inadequate therapeutic response to parenteral corticosteroids in patients with acute bronchial asthma is infrequent. We report four patients whose bronchial asthma symptoms worsened after treatment with parenteral corticosteroids. All had larvae of Strongyloides stercoralis in the stool. The new attack or the exacerbation of asthma appeared to be precipitated by systemic corticosteroid administration. The paradoxic therapeutic response of asthma to glucocorticoides was the major pulmonary manifestation of Strongyloides superinfection; there was no evidence of other organ involvement. Individuals with new onset of bronchial asthma or worsening of asthmatic episodes concurrent with the use of systemic corticosteroids should have thorough investigation for possible superinfection due to Strongyloides stercoralis. This is particularly important for patients who have resided in areas where intestinal helminthic infections are endemic. Discontinuance of steroid therapy or reduction in dosage of parenteral steroids appears necessary. Treatment with thiabendazole appears to be effective in patients with limited hyperinfection syndrome.

    Objective: To analyze CT portal venography (CTPV) manifestations of portal collateral circulation in patients with cirrhosis by using a 16-detector row spiral CT scanner. Methods: CTPV was performed in 36 patients with portal hypertension due to cirrhosis, the diagnosis was proved by clinical data, hepatic function findings and imaging signs. By using post-processing reconstruction technique, 3D images of portal venous system and portal collateral circulation were obtained. Results: CTPV images displayed the portal venous system and its collateral circulation stereoscopically. Of 36 patients, left gastric varices were seen in 29(80.6%), lower esophageal varices in 18(50.0%), short gastric or posterior gastric varices in 15(41.7%), paraesophageal varices in 9(25.0%), gastro-renal or splenorenal shunts in 8(22.2%), spongelike transformation of portal vein in 7(19.4%), paraumbilical and abdominal wall varices in 6(16.7%), congenital cavernous in 6(16.7%) and paravertebral venous shunts in 4(11.1%). Conclusion: CTPV can well display the site, extent and severity of the portal collateral circulation in patients with portal hypertension due to cirrhosis,which is of great clinical importance for judging the patient's condition, for selecting therapeutic protocols and for estimating prognosis.

    Since 2015, 84 countries and territories reported evidence of vector-borne Zika Virus (ZIKV) transmission. The World Health Organization (WHO) declared that ZIKV and associated consequences especially the neurological autoimmune disorder Guillain–Barré syndrome (GBS) and microcephaly will remain a significant enduring public health challenge requiring intense action. We apply a standardization of the multi-subcutaneous dorsal inoculation method to systematically summarize clinical neurological manifestation, viral distribution, and tissue damage during the progress of viremia and systemic spread in suckling mouse models. We found that C57BL/6 and Kunming mice (KM) both showed remarkable and uniform neurologic manifestations. C57BL/6 owned the highest susceptibility and pathogenicity to the nervous system, referred to as movement disorders, with 100% incidence, while KM was an economic model for a Chinese study characterized by lower limb weakness with 62% morbidity. Slight yellow extraocular exudates were observed in BALB/c, suggesting the association with similar ocular findings to those of clinical cases. The virus distribution and pathological changes in the sera, brains, livers, kidneys, spleens, and testes during disease progression had strong regularity and uniformity, demonstrating the effectiveness and plasticity of the animal models. The successful establishment of these animal models will be conducive to expound the pathogenic mechanism of GBS. PMID:28661429

    B+NK+SCID (severe combined immunodeficiency) due to IL7Rα deficiency represents approximately 10% of American SCID cases. To better understand the spectrum of autoimmune disorders associated with IL7Rα deficiency, we describe two unrelated IL7Rα-deficient female SCID infants whose clinical picture was dominated by autoimmune manifestations: one with intrauterine Omenn syndrome (OS) and another with persistent thrombocytopenic purpura since 4months of age. The OS baby harbored a homozygous p.C118Y mutation in IL7R. She presented dense eosinophilic infiltrates in several organs, including pancarditis, which may have contributed to her death (on the 2nd day of life). B cells were observed in lymph nodes, spleen, bone marrow and thymus. The second patient harbored compound heterozygous p.C118Y and p.I121NfsX8 mutations. She underwent a successful unrelated cord blood transplant. In conclusion, early OS can be observed in patients with IL7R mutations, and autoimmune cytopenias could also complicate the clinical course of SCID babies with this type of defect. Copyright © 2014.

    The two autosomal dominantly inherited neurological diseases: familial hemiplegic migraine type 2 (FHM2) and familial rapid-onset of dystonia-parkinsonism (Familial RDP) are caused by in vivo mutations of specific alpha subunits of the sodium–potassium pump (Na+/K+-ATPase). Intriguingly, patients...... with classical FHM2 and RDP symptoms additionally suffer from other manifestations, such as epilepsy/seizures and developmental disabilities. Recent studies of FHM2 and RDP mouse models provide valuable tools for dissecting the vital roles of the Na+/K+-ATPases, and we discuss their relevance to the complex...

  13. Complex neurological symptoms in bilateral thalamic stroke due to Percheron artery occlusion.

    Science.gov (United States)

    Caruso, Paola; Manganotti, Paolo; Moretti, Rita

    2017-01-01

    The artery of Percheron is a rare anatomical variant where a single thalamic perforating artery arises from the proximal posterior cerebral artery (P1 segment) between the basilar artery and the posterior communicating artery and supplies the rostral mesencephalon and both paramedian territories of the thalami. Almost one-third of human brains present this variant. Occlusion of the artery of Percheron mostly results in a bilateral medial thalamic infarction, which usually manifests with altered consciousness (including coma), vertical gaze paresis, and cognitive disturbance. The presentation is similar to the "top of the basilar syndrome", and early recognition should be prompted. We describe the case of a young female with this vessel variant who experienced a bilateral thalamic stroke. Magnetic resonance angiography demonstrated bilateral thalamic infarcts and a truncated artery of Percheron. Occlusion of the vessel was presumably due to embolism from a patent foramen ovale. Thrombolysis was performed, with incomplete symptom remission, cognitive impairment, and persistence of speech disorders. Early recognition and treatment of posterior circulation strokes is mandatory, and further investigation for underlying stroke etiologies is needed.

    Full Text Available Celiac disease (CD/ Nontropicalsprue, gluten-sensitive enteropathy is a malabsortive condition in which an allergic reaction to the cereal grain-protein gluten (present in wheat, rye and barley causes small intestine mucosal injury. The onset is in the first four decades of life, with a female to male ratio of 2:1. It may be associated with a wide spectrum of neurological manifestations including cerebellar ataxia, epileptic seizures, dementia, neuropathy, myopathy and multifocal leucoencephalopathy. We report three patients with neurological manifestations related with CD: one with cerebellar ataxia, one with epilepsy and one with cognitive impairment. The diagnosis of CD was confirmed by serologic tests (antiendomysial and antigliadin antibodies and biopsy of the small intestine. In two patients the neurological symptoms preceded the gastrointestinal abnormalities and in all of them gluten restriction failed to improve the neurological disability. Conclusion: CD should be ruled out in the differential diagnosis of neurological dysfunction of unknown cause, including ataxia, epilepsy and dementia. A gluten free diet, the mainstay of treatment, failed to improve the neurological disability.A doença celíaca (DC, enteropatia sensível ao glúten é desordem caracterizada por mal absorção causada por reação alérgica ao glúten, proteína presente em diversos cereais.

    1996-01-01

    What conclusions can be drawn concerning the potential neurological effects of perinatal exposure to either PCBs, or PCBs and other fish-borne contaminants? First, by their very nature epidemiological studies are limited in their ability to detect subtle associations--including possible links between exposure to low levels of environmental contaminants and disease. As stated by Dr. Schantz, both Rogan and the Jacobsons report small changes in motor and cognitive behavior--typically less than one-half of a standard deviation--and only in the most highly exposed children. Given these small changes in CNS function, the substantive criticisms of Paneth (including the Jacobsons' choice to employ a random, rather than matched, control sample and the related fact that fish-eating mothers differed from non-fish-eating mothers on several important characteristics) and similar "generic" concerns raised by Taubes, a critical reader must question both the validity of the findings from the Michigan study and the reasons for discrepancies in results between the Jacobson and Rogan studies. Are the differences in neurobehavioral effects reported by the Jacobsons and colleagues, and Rogan and colleagues, due to the presence of confounders, exposure to different neurotoxicants, or subtle differences in methodologies? At present it is not possible to answer these questions. Nevertheless, certain commonalities exist between the Rogan and Jacobson studies, and most recently, the study conducted by Daly and colleagues in New York. All of these studies report alterations in the Brazelton Neonatal Behavioral Assessment Scale, suggesting that exposure to environmental contaminants (including PCBs) may induce subtle, transient alterations in maturation of the human CNS. Secondly, because contaminated fish contain a large number of putative developmental neurotoxicants (e.g., methyl-mercury, p,p'-DDE, PCBs, and pesticides), I am pessimistic that additional studies of human populations

    A 41-year-old man visited our dermatology clinic because an eruption, which was resistant to steroid ointment treatment, had appeared on his right forearm. An oval, soybean-sized erythematous infiltrated lesion with scales and crusts was located in the central part of the extensor surface of the right forearm and showed partial erosion with attached yellow crusts. The lesion had an impetigo-like appearance. Fungal elements were confirmed from the scales by KOH examination and the fungus was identified as Trichophyton tonsurans by fungal culture and molecular method. Clinical features of T. tonsurans infection vary, wherein some patients have strong inflammatory manifestations, while others remain as asymptomatic carriers. Especially at the early stage of the infection, diagnosis is difficult because it is often misdiagnosed as eczema. We report a case of T. tonsurans infection that had impetigo-like appearance. We also studied the mechanism of the disease.

    One hypothesis that couples infection with autoimmune disease is molecular mimicry. Molecular mimicry is characterized by an immune response to an environmental agent that cross-reacts with a host antigen, resulting in disease. This hypothesis has been implicated in the pathogenesis of diabetes, lupus and multiple sclerosis (MS). There is limited direct evidence linking causative agents with pathogenic immune reactions in these diseases. Our study establishes a clear link between viral infection, autoimmunity and neurological disease in humans. As a model for molecular mimicry, we studied patients with human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP), a disease that can be indistinguishable from MS (refs. 5,6,7). HAM/TSP patients develop antibodies to neurons. We hypothesized these antibodies would identify a central nervous system (CNS) autoantigen. Immunoglobulin G isolated from HAM/TSP patients identified heterogeneous nuclear ribonuclear protein-A1 (hnRNP-A1) as the autoantigen. Antibodies to hnRNP-A1 cross-reacted with HTLV-1-tax, the immune response to which is associated with HAM/TSP (refs. 5,9). Immunoglobulin G specifically stained human Betz cells, whose axons are preferentially damaged. Infusion of autoantibodies in brain sections inhibited neuronal firing, indicative of their pathogenic nature. These data demonstrate the importance of molecular mimicry between an infecting agent and hnRNP-A1 in autoimmune disease of the CNS.

    Full Text Available Abstract Introduction Hemangioblastomas are rare, benign tumors occurring in any part of the nervous system. Most are found as sporadic tumors in the cerebellum or spinal cord. However, these neoplasms are also associated with von Hippel-Lindau disease. We report a rare case of a sporadic sellar hemangioblastoma that became symptomatic due to pituitary apoplexy. Case presentation An 80-year-old, otherwise healthy Caucasian woman presented to our facility with severe headache attacks, hypocortisolism and blurred vision. A magnetic resonance imaging scan showed an acute hemorrhage of a known, stable and asymptomatic sellar mass lesion with chiasmatic compression accounting for our patient's acute visual impairment. The tumor was resected by a transnasal, transsphenoidal approach and histological examination revealed a capillary hemangioblastoma (World Health Organization grade I. Our patient recovered well and substitutional therapy was started for panhypopituitarism. A follow-up magnetic resonance imaging scan performed 16 months postoperatively showed good chiasmatic decompression with no tumor recurrence. Conclusions A review of the literature confirmed supratentorial locations of hemangioblastomas to be very unusual, especially within the sellar region. However, intrasellar hemangioblastoma must be considered in the differential diagnosis of pituitary apoplexy.

    This study is aimed to explore the combined use of goiter dispersion formula and antithyroid drugs in the treatment of patients with neurologic manifestations of Graves' disease by examining its modulating effects on patients' cytokines. A total of 80 patients with Graves' disease were randomly divided into treatment and control groups. Patients of the treatment group received goiter dispersion formula and antithyroid drugs (methimazole or propylthiouracil), whereas those of the control group received antithyroid drug alone. FT3, FT4, and TSH contents were detected by chemiluminescence immunoassay at pre- and post-treatment; interleukin (IL)-2, IL-8, and IL-17 serum levels before and after the treatment were detected by radioimmunoassay; thyroid B-mode ultrasound and liver and renal function tests were performed in all patients of both groups. An additional cohort of 40 healthy subjects was recruited for baseline measurement. All the enrolled patients completed the trial. The effective treatment rate was higher in the treatment group than in the control group, of which the difference was statistically significant (treatment group, 95%; control group, 75%, p Graves' disease comparing with those in healthy subjects (p Graves' disease by modulating IL-2, IL-8, and IL-17. The data supported the rationale for the use of goiter dispersion formula in Graves' disease treatment.

    Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe hypertension. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia. © 2017 Japan Society of Obstetrics and Gynecology.

    Central nervous system symptoms in patients with primary Sjogren`s syndrome are rare. They can present as extraglandular manifestations and require a differential diagnosis from multiple sclerosis. Due to a variety of presentations, Sjogren`s syndrome with neurologic involvement may be difficult to diagnose. Here, we report a case of a 75-year-old woman who was first diagnosed with multiple sclerosis in 2010, but who was subsequently diagnosed with primary Sjogren`s syndrome 2 years later after showing signs of atypical neurologic manifestations. Therefore, primary Sjogren`s syndrome should be suspected in patients who present with atypical clinical and radiologic neurologic manifestations.

    Full Text Available BACKGROUND This prospective study aimed to evaluate the incidence of ocular manifestations in head injury and their correlation with the intracranial lesions. MATERIALS AND METHODS A total of 108 consecutive cases of closed head injury admitted in the neurosurgical ward of a tertiary teaching hospital underwent a thorough ophthalmic assessment. Clinical examination, radiological imaging and Glasgow Coma Scale (GCS were applied to grade the severity of injury. RESULTS Total number of 108 patients of head injury were examined of which 38 patients had ocular manifestations (35.18%. Of these, 85.18% were males, 84% of injuries were due to road traffic accidents and 16% were due to fall from a height. The ocular manifestations were as follows- Orbital complications were seen in 6 patients (15.8%. Anterior segment manifestations included black eyes seen in 10 patients (26.3%, subconjunctival haemorrhage in 10.5% of patients (4 patients, corneal involvement in 21% of patients (8 patients and pupillary involvement in 50% of patients (19 patients. Posterior segment manifestations were seen in 26.3% of patients (10 patients and were as follows- Purtscher’s retinopathy in 2 patients and optic atrophy in 5 patients. Cranial nerve palsies were seen in 15 patients (39.47% and supranuclear movement disorders were seen in 3 patients (8%. CONCLUSION Even though, neurosurgeons perform comprehensive clinical examination including eye examination, the main purpose is limited to aid topical diagnosis of neurological lesions. This study emphasises the importance of a detailed eye examination by an ophthalmologist to prevent irreversible visual loss in addition to aiding in the neurological diagnosis. Pupillary involvement, papilloedema and ocular motor paresis pointed to a more severe head injury. This observational prospective study helped us to correlate the severity of head injuries in association with ocular findings in patients admitted in neurosurgical ward

    Sensory nerve degeneration and consequent abnormal sensations are the earliest and most prevalent manifestations of familial amyloid polyneuropathy (FAP) due to amyloidogenic transthyretin (TTR). FAP is a relentlessly progressive degenerative disease of the peripheral nervous system. However, there is a lack of mouse models to replicate the early neuropathic manifestations of FAP. We established human TTR knock-in mice by replacing one allele of the mouse Ttr locus with human wild-type TTR (hTTR wt ) or human TTR with the A97S mutation (hTTR A97S ). Given the late onset of neuropathic manifestations in A97S-FAP, we investigated nerve pathology, physiology, and behavioural tests in these mice at two age points: the adult group (8 - 56 weeks) and the ageing group (> 104 weeks). In the adult group, nerve profiles, neurophysiology and behaviour were similar between hTTR wt and hTTR A97S mice. By contrast, ageing hTTR A97S mice showed small fibre neuropathy with decreased intraepidermal nerve fibre density and behavioural signs of mechanical allodynia. Furthermore, significant reductions in sural nerve myelinated nerve fibre density and sensory nerve action potential amplitudes in these mice indicated degeneration of large sensory fibres. The unaffected motor nerve physiology replicated the early symptoms of FAP patients, that is, sensory nerves were more vulnerable to mutant TTR than motor nerves. These results demonstrate that the hTTR A97S mouse model develops sensory nerve pathology and corresponding physiology mimicking A97S-FAP and provides a platform to develop new therapies for the early stage of A97S-FAP. © 2018 British Neuropathological Society.

    Full Text Available Scrub typhus is caused by Orientia tsutsugamushi characterized by focal or disseminated vasculitis and perivasculitis which may involve the lungs, heart, liver, spleen and central nervous system. It was thought to have been eradicated from India. Recently it is being reported from many areas of India. The clinical picture and severity of the symptoms varies widely. The neurological manifestations of scrub typhus are not uncommon but are diverse. Meningoencephalitis is classical manifestation of scrub typhus but cerebellitis, cranial nerve palsies, plexopathy, transverse myelitis, neuroleptic malignant syndrome and Guillan-Barré syndrome are other manifestations reported in literature. The availability of literature on the neurological manifestations of scrub typhus is limited to case reports mainly. This article reviews various neurological manifestations of scrub typhus reported in literature.

    Historically, diphtheria was a major cause of morbidity and mortality in the prevaccine era. However, in recent times there has been a resurgence of diphtheria, especially in the newly independent states of the former USSR. Diphtheritic polyneuropathy can be a serious complication in patients who have a severe infection. In patients with pertussis, seizures and encephalopathy can occur as a complication of asphyxia. Vaccination against diphtheria and pertussis in children and booster vaccination in adults is recommended. DTP (diphtheria, tetanus, pertussis) vaccination has been shown to increase the risk of febrile seizures in children. Currently, it appears that the risk of vaccine-induced encephalopathy and/or epilepsy following DTP vaccination, if any, is extremely low. © 2014 Elsevier B.V. All rights reserved.

  10. Neurological disorders in hypertensive patients

    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.

    Full Text Available Purpose. Understanding the presentation of spinal cord injury (SCI due to tumours considering population distribution and temporal trends is key to managing SCI health services. This study quantified incidence rates, function scores, and trends of SCI due to tumour or metastasis over an 18-year time period in a defined region in Spain. Methods. A retrospective cohort study included in-and outpatients with nontraumatic SCI due to tumour or metastasis admitted to a metropolitan hospital in Spain between 1991 and 2008. Main outcome measures were crude and age- and sex-adjusted incidence rates, tumour location and type, distribution by spinal level, neurological level of injury, and impairment ASIA scores. Results. Primary tumour or metastasis accounted for 32.5% of nontraumatic SCI with an incidence rate of 4.1 per million population. Increasing rates with age and over time were observed. Major pathology groups were intradural-extramedullary masses from which meningiomas and neurinomas accounted for 40%. Lesions were mostly incomplete with predominant ASIA Grade D. Conclusions. Increasing incidence rates of tumour-related SCI over time in the middle-aged and the elderly suggest a growing need for neurooncology health resources in the future.

    2010-02-01

    This review is devised to gather the presently known inborn errors of purine metabolism that manifest neurological pediatric syndromes. The aim is to draw a comprehensive picture of these rare diseases, characterized by unexpected and often devastating neurological symptoms. Although investigated for many years, most purine metabolism disorders associated to psychomotor dysfunctions still hide the molecular link between the metabolic derangement and the neurological manifestations. This basically indicates that many of the actual functions of nucleosides and nucleotides in the development and function of several organs, in particular central nervous system, are still unknown. Both superactivity and deficiency of phosphoribosylpyrophosphate synthetase cause hereditary disorders characterized, in most cases, by neurological impairments. The deficiency of adenylosuccinate lyase and 5-amino-4-imidazolecarboxamide ribotide transformylase/IMP cyclohydrolase, both belonging to the de novo purine synthesis pathway, is also associated to severe neurological manifestations. Among catabolic enzymes, hyperactivity of ectosolic 5'-nucleotidase, as well as deficiency of purine nucleoside phosphorylase and adenosine deaminase also lead to syndromes affecting the central nervous system. The most severe pathologies are associated to the deficiency of the salvage pathway enzymes hypoxanthine-guanine phosphoribosyltransferase and deoxyguanosine kinase: the former due to an unexplained adverse effect exerted on the development and/or differentiation of dopaminergic neurons, the latter due to a clear impairment of mitochondrial functions. The assessment of hypo- or hyperuricemic conditions is suggestive of purine enzyme dysfunctions, but most disorders of purine metabolism may escape the clinical investigation because they are not associated to these metabolic derangements. This review may represent a starting point stimulating both scientists and physicians involved in the study of

    The authors present divergent opinions on the pathogenesis of vibratory syndrome, and primarily on its angio-neurological form, i.e. vascular, neurogenic and immunological theory. In the light of these concepts the clinical manifestations of vibratory syndrome are discussed in view of both systemic and local developments. The issues concerning neurological diagnostics with reference to the usefulness of electrophysiological methods are thoroughly analysed. Difficulties in early diagnosis and identification of symptoms that distinguish vibratory syndrome from other syndromes with similar manifestations are highlighted.

    Thallium intoxication was reported in cases with accidental ingestion, suicide attempt, and criminal adulteration. Reported cases were mostly one-time ingestion, therefore, the clinical course of divisional ingestion has not been fully known. Here, we report a case with two-step thallium intoxication manifesting as tardily accelerated neurologic deterioration. A 16-year-old adolescent was cryptically poisoned with thallium sulfate twice at an interval of 52days. After the first ingestion, neurologic symptoms including visual loss, myalgia, and weakness in legs developed about 40days after the development of acute gastrointestinal symptoms and alopecia. After the second ingestion, neurologic symptoms deteriorated rapidly and severely without gastrointestinal or cutaneous symptoms. Brain magnetic resonance imaging exhibited bilateral optic nerve atrophy. Nerve conduction studies revealed severe peripheral neuropathies in legs. Thallium intoxication was confirmed by an increase in urine thallium egestion. Most of the neurologic manifestations ameliorated in two years, but the visual loss persisted. The source of thallium ingestion was unraveled afterward because a murder suspect in another homicidal assault confessed the forepast adulteration. This discriminating clinical course may be attributable to the cumulative neurotoxicity due to the longer washout-time of thallium in the nervous system than other organs. It is noteworthy that the divisional thallium intoxication may manifest as progressive optic and peripheral neuropathy without gastrointestinal or cutaneous symptoms. Copyright © 2016 Elsevier Ltd.

  19. Neurological aspects of lead intoxication

    This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

    2008-07-01

    Full Text Available Abstract Background Previous research by the authors found evidence that up to 10% of particular household categories may be exposed to elevated carbon monoxide (CO concentrations from poor quality gas appliance installations. The literature suggests certain neurological symptoms are linked to exposure to low levels of CO. This paper addresses the hypothesis that certain self-reported neurological symptoms experienced by a householder are linked to an estimate of their CO exposure. Methods Between 27 April and 27 June 2006, 597 homes with a mains supply of natural gas were surveyed, mainly in old, urban areas of London. Qualified gas engineers tested all gas appliances (cooker, boiler, gas fire, and water heater and reported, according to the Gas Industry Unsafe Situations Procedure, appliances considered At Risk (AR, Immediately Dangerous (ID or Not to Current Standards (NCS. Five exposure risk categories were defined based on measurement of CO emitted by the appliance, its features and its use, with "high or very high" exposure category where occupants were considered likely to be exposed to levels greater than 26 ppm for one hour. The prevalence of symptoms at each level of exposure was compared with that at lowest level of exposure. Results Of the households, 6% were assessed as having a "high or very high" risk of exposure to CO. Of the individuals, 9% reported at least one neurological symptom. There was a statistically significant association between "high or very high" exposure risk to CO and self-reported symptoms compared to "no exposure" likelihood, for households not in receipt of benefit, controlling for "number of residents" and presence of pensioners, OR = 3.23 (95%CI: 1.28, 8.15. Risk ratios across all categories of exposure likelihood indicate a dose-response pattern. Those households in receipt of benefit showed no dose-response pattern. Conclusion This study found an association between risk of CO exposure at low concentration

    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.

    The article summarizes the results of clinical, neurological, and laboratory examination of patients with hyperhomocysteinemia. The data obtained suggest the existence of common pathobiochemical mechanisms of homocystein, cholesterol, and myelin dysmetabolism. The authors demonstrate that neurological manifestations of hyperhomocysteinemia are associated with the processes of demyelinization in the central and peripheral nervous systems.

    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

  7. Extrathoracic manifestations of tuberculosis

    Kienzl-Palma, D.; Prosch, H.

    2016-01-01

    Besides the lungs, tuberculosis (TB) can affect any organ system. In most cases, extrathoracic TB occurs in immunosuppressed patients as part of a severe illness via hematogenous spread. Extrathoracic involvement most commonly involves abdominal organs, especially the urogenital tract and less commonly the central nervous system (CNS) and the musculoskeletal system. Most frequently, computed tomography (CT) is used for detecting extrathoracic TB manifestations, except for CNS and musculoskeletal manifestations, where contrast-enhanced magnetic resonance imaging (MRI) is the gold standard. Extrathoracic manifestations of TB may be indistinguishable from inflammatory or malignant causes. Due to unspecific symptoms the diagnosis is often delayed. This article summarizes and discusses the various radiological manifestations of extrathoracic manifestation of TB. Radiological modalities for screening extrathoracic TB are CT and MRI. Conventional X-radiographs do not play a role in the diagnosis of extrathoracic TB. The possibility of extrathoracic TB should be considered particularly in immunosuppressed patients, such as the homeless, alcoholics or drug addicts or in patients with an immigrant background from the endemic areas of TB. The most likely site of extrathoracic TB is the abdomen; however, infections of the CNS or musculoskeletal systems and multisystem infections can also occur. In patients with suspected extrathoracic TB, radiological modalities for screening are CT, especially for abdominal infections and lymphadenopathy and MRI with contrast media for the musculoskeletal system and the CNS.

    2006-09-01

    Retinitis pigmentosa (RP) refers to a group of inherited retinal diseases with phenotypic and genetic heterogeneity. The pathophysiologic basis of the progressive visual loss in patients with RP is not completely understood but is felt to be due to a primary retinal photoreceptor cell degenerative process mainly affecting the rods of the peripheral retina. In most cases RP is seen in isolation (nonsyndromic), but in some other cases it may be a part of a genetic, metabolic, or neurologic syndrome or disorder. Nyctalopia, or night blindness, is the most common symptom of RP. The classic fundus appearance of RP includes retinal pigment epithelial cell changes resulting in retinal hypo- or hyperpigmentation ("salt-and-pepper"), retinal granularity, and bone spicule formation. The retinal vessels are often narrowed or attenuated and there is a waxy pallor appearance of the optic nerve head. Electroretinography will demonstrate rod and cone photoreceptor cell dysfunction and is a helpful test in the diagnosis and monitoring of patients with RP. A detailed history with pedigree analysis, a complete ocular examination, and the appropriate paraclinical testing should be performed in patients complaining of visual difficulties at night or in dim light. This review discusses the clinical manifestations of RP as well as describing the various systemic diseases, with a special emphasis on neurologic diseases, associated with a pigmentary retinopathy.

  10. Vertigo as a Predominant Manifestation of Neurosarcoidosis

    2015-01-01

    Full Text Available Sarcoidosis is a granulomatous disease of unknown etiology that affects multiple organ systems. Neurological manifestations of sarcoidosis are less common and can include cranial neuropathies and intracranial lesions. We report the case of a 21-year-old man who presented with vertigo and uveitis. Extensive workup including brain imaging revealed enhancing focal lesions. A lacrimal gland biopsy confirmed the diagnosis of sarcoidosis. The patient was initially treated with prednisone, which did not adequately control his symptoms, and then was switched to methotrexate with moderate symptomatic improvement. Our patient had an atypical presentation with vertigo as the predominant manifestation of sarcoidosis. Patients with neurosarcoidosis typically present with systemic involvement of sarcoidosis followed by neurologic involvement. Vertigo is rarely reported as an initial manifestation. This case highlights the importance of consideration of neurosarcoidosis as an entity even in patients that may not have a typical presentation or systemic involvement of disease.

    2014-01-01

    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

    Full Text Available West Nile virus infection in humans is mostly asymptomatic. Less than 1% of neuro-invasive cases show a fatality rate of around 10%. Acute flaccid paralysis of respiratory muscles leading to respiratory failure is the most common cause of death. Although the peripheral nervous system can be involved, isolated phrenic nerve palsy leading to respiratory failure is rare and described in only two cases in the English literature. We present another case of neurological respiratory failure due to West Nile virus-induced phrenic nerve palsy. Our case reiterates the rare, but lethal, consequences of West Nile virus infection, and the increase of its awareness among physicians.

    Endocrine diseases may result in changes in cutaneous function and morphology, which cause various skin manifestations, including nonspecific or pathognomonic signs. Some of these manifestations are already known dermatologic diseases with only increased frequency in this patient group. As a result the skin may the play role of a screen displaying endocrine disorders, either due to hormone excess or deficiency. Awareness of the skin manifestations may permit prompt and adequate approach to the patients, and therefore facilitate the early diagnosis of the endocrine disease and even be life saving. Some of these manifestations may be recognized clinically, but sometimes they need to be confirmed histopathologically. In this article, many endocrine diseases and their associated skin lesions will be reviewed briefly.

    Lim, K.S.; Chong, V.H.

    2010-01-01

    Melioidosis is a serious infection that is associated with high mortality. It is due to a Gram-negative bacterium, Burkholderia pseudomallei which is an environmental saprophyte found in wet soils. Melioidosis is endemic to northern Australia and the Southeast Asia. However, there is now increasing number of reports of imported cases to regions where this infection has not been previously encountered. Almost any organ can be affected. Like many other conditions, radiological imaging is an integral part of the diagnostic workup of melioidosis. Awareness of the various radiological manifestations can help direct appropriate investigations to achieve early diagnosis and the initiation of appropriate treatment. Generally, there are no known characteristic features on imaging that can specifically differentiate melioidosis from other infections. However, the 'honeycomb' appearance has been described to be characteristic for large melioidosis liver abscesses. Simultaneous involvement of various organs is also characteristics. To date, there are few data available on the radiological manifestations of melioidosis. The present pictorial essay describes melioidosis affecting the various organs.

    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.

    2011-11-29

    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. Pelvic hydatid cyst with uncommon sciatalgia manifestation: a case report

    Directory of Open Access Journals (Sweden)

    Ghodratolah Maddah

    2013-11-01

    Full Text Available Background: Hydatid disease or echinococcosis is a common parasitic disease of human and bovine, caused by infection with larva of the cestode echinococcus. Liver is the most common organ that is involved in this disease. Pelvic involvement and neurological symptoms, due to mass effect of pelvic involvement, in lower extremities are very uncommon manifestations of the disease.Case presentation: A forty six year old man was referred to clinic of surgery at Ghaem Hospital, Medical University of Mashhad, Iran. The patient complained about weakness and motor impairment in right lower extremity accompanied by numbness and radicular pain over past two months. Physical examination demonstrated muscular atrophy and reduced muscular strength in right lower extremity. Computed tomography and ultrasonographic studies showed a cystic mass in right side of the pelvic cavity with extention to the sciatic notch and another cystic mass in right gluteal region. Surgical operation revealed a cystic mass deep in pelvic cavity with the extention to the right sciatic notch with compression of nerve roots. The cystic mass was contained of daughter cysts which confirmed the diagnosis of hydatid cyst disease. This diagnosis was confirmed by pathologic assessment.Conclusion: Although uncommon, but hydatid disease can involve the pelvic cavity and make a pelvic, usually cystic, mass; that can make compression on nerve roots and so making neurologic symptoms in lower extremities. So in endemic areas for hydatid disease, such as Iran, pelvic hydatid cysts should be considered as a possible differential diagnosis in patients presenting with the sciatic pain and neurological manifestations in whom a pelvic mass has been found too.

    2012-01-01

    Full Text Available Sjögren's syndrome is an autoimmune disease characterized by an autoimmune exocrinopathy involving mainly salivary and lacrimal glands. The histopathological hallmark is periductal lymphocytic infiltration of the exocrine glands, resulting in loss of their secretory function. Several systemic manifestations may be found in patients with Sjögren's syndrome including neurological disorders. Neurological involvement ranges from 0 to 70% among various series and may present with central nervous system and/or peripheral nervous system involvement. This paper endeavors to review the main clinical neurological manifestations in Sjögren syndrome, the physiopathology, and their therapeutic response.

    2012-11-01

    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.

    There has been remarkable progress in the identification of mutations in genes that cause inherited neurological disorders. Abnormalities in the genes for Huntington disease, neurofibromatosis types 1 and 2, one form of familial amyotrophic lateral sclerosis, fragile X syndrome, myotonic dystrophy, Kennedy syndrome, Menkes disease, and several forms of retinitis pigmentosa have been elucidated. Rare disorders of neuronal migration such as Kallmann syndrome, Miller-Dieker syndrome, and Norrie disease have been shown to be due to specific gene defects. Several muscle disorders characterized by abnormal membrane excitability have been defined as mutations of the muscle sodium or chloride channels. These advances provide opportunity for accurate molecular diagnosis of at-risk individuals and are the harbinger of new approaches to therapy of these diseases.

  3. Neurologic emergencies in sports.

    Williams, Vernon B

    2014-12-01

    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.

    2009-01-01

    Meningeal carcinomatosis is defined as the malignant and widespread infiltration of the meninges due to the planting and growth of cancer cells within the leptomeningeal space. It occurs more frequently in patients with disseminated neoplastic disease, but it may occur after a disease free interval and may even be the first manifestation of cancer. The most common primary tumors in adults are breast (30-50%), lung (15-25%), melanoma (11%) and gastric cancer (0.16-0.69%); in marked contrast with pediatric cases in which lymphocytic leukemia is the most common. The following article describes an autopsy case of a patient with psychiatric symptoms, with no antecedents of importance, with progressive and fatal neurological impairment, whose pathological studies show meningeal carcinomatosis attributable to advanced gastric adenocarcinoma discovered de novo post mortem.

  8. Neurophysiologic studies of functional neurologic disorders.

    Science.gov (United States)

    Hallett, M

    2016-01-01

    Functional neurologic disorders are largely genuine and represent conversion disorders, where the dysfunction is unconscious, but there are some that are factitious, where the abnormality is feigned and conscious. Malingering, which can have the same manifestations, is similarly feigned, but not considered a genuine disease. There are no good methods for differentiating these three entities at the present time. Physiologic studies of functional weakness and sensory loss reveal normal functioning of primary motor and sensory cortex, but abnormalities of premotor cortex and association cortices. This suggests a top-down influence creating the dysfunction. Studies of functional tremor and myoclonus show that these disorders utilize normal voluntary motor structures to produce the involuntary movements, again suggesting a higher-level abnormality. Agency is abnormal and studies shows that dysfunction of the temporoparietal junction may be a correlate. The limbic system is overactive and might initiate involuntary movements, but the mechanism for this is not known. The limbic system would then be the source of top-down dysfunction. It can be speculated that the involuntary movements are involuntary due to lack of proper feedforward signaling. © 2016 Elsevier B.V. All rights reserved.

  9. Neurology of ciguatera

    Pearn, J

    2001-01-01

    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.

    2008-01-01

    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.

    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

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.

    Guerrero-Peral, A L

    In the medieval period, physicians became more aware of leprosy symptoms and differentiated it from other similar diseases. Baldwin, the leper king of Jerusalem (1161-1185), probably contributed to an increasing interest and tolerance to this disease in medieval Christian states. We review historical descriptions of the neurological manifestations he developed. William of Tyre gives us a description of first symptoms experienced by the prince when aged nine. He notices that half of his right arm and hand were partially numb. No skin or nervous lesions are described. By his early twenties, muscle weakness makes him unable to walk. He gets blinded, probably due to keratopathy related to facial nerves involvement. Repeated attacks of fever lead to progressive worsening of his disease. He finally dies in Jerusalem, aged twenty-five, probably due to a septicaemia from infected sores. The earliest sign of Baldwin's disease is anaesthesia. Though skin lesions are not described, it is likely that at this point he had a tuberculoid form of leprosy. As his disease finally takes a lepromatous form, we suspect that it began as a borderline, immunologically unstable form. Leper king Baldwin biography gives us interesting descriptions of neurological clinical features of leprosy. Besides, it helps us to discover twelfth century medicine knowledge about this disease.

    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

    Summary Neurology is a field known for “eponymophilia.” While eponym use has been a controversial issue in medicine, animal-related metaphoric descriptions continue to flourish in neurologic practice, particularly with the advent of neuroimaging. To provide practicing and trainee neurologists with a useful reference for all these colorful eponyms, we performed a literature review and summarized the various animal eponyms in the practice of neurology (and their etiologic implications) to date. We believe that the ability to recognize animal-like attributes in clinical neurology and neuroradiology may be attributed to a visual phenomenon known as pareidolia. We propose that animal eponyms are a useful method of recognizing clinical and radiologic patterns that aid in the diagnostic process and therefore are effective aidesmémoire and communicative tools that enliven and improve the practice of neurology.

    To determine the percentage of Lyme patients with articular manifestations in NW Spain and to know their evolution and response to treatment. A retrospective study (2006-2013) was performed using medical histories of confirmed cases of Lyme disease showing articular manifestations. Clinical and laboratory characteristics, together with the treatment and evolution of the patients, were analysed. Seventeen out of 108 LD confirmed patients (15.7%) showed articular manifestations. Regarding those 17 patients, 64.7%, 29.4% and 5.9% presented arthritis, arthralgia and bursitis, respectively. The knee was the most affected joint. Articular manifestations were often associated to neurological, dermatological and cardiac pathologies. Otherwise, most patients were in Stage III. The 11.8% of the cases progressed to a recurrent chronic arthritis despite the administration of an appropriate treatment. Lyme disease patients showing articular manifestations should be included in the diagnosis of articular affections in areas of high risk of hard tick bite, in order to establish a suitable and early treatment and to avoid sequels.

    Full Text Available Objective. To identify the role of thrombolytic therapy in acute embolic stroke due to infective endocarditis. Design. Case report. Setting. University hospital. Patient. A 70-year-old male presented with acute onset aphasia and hemiparesis due to infective endocarditis. His head computerized tomographic scan revealed left parietal sulcal effacement. He was given intravenous tissue plasminogen activator with significant resolution of the neurologic deficits without complications. Main Outcome Measures. Physical examination, National Institute of Health Stroke Scale, radiologic examination results. Conclusions. Thrombolytic therapy in selected cases of stroke due to infective endocarditis manifesting as major neurologic deficits can be considered as an option after careful consideration of risks and benefits. The basis for such favorable response rests in the presence of fibrin as a major constituent of the vegetation. The risk of precipitating hemorrhage with thrombolytic therapy especially with large infarcts and mycotic aneurysms should be weighed against the benefits of averting a major neurologic deficit.

    Hypochrondroplasia is an inherited skeletal dysplasia that resembles achondroplasia in mild degree. Radiographic manifestations encountered in 12 affected individuals in South Africa include slight shortening of all segments of the tubular bones, moderate caudal diminution of the lumbar interpedicular distances, increased lumbar lordosis with cacral tilt and distal prolongation of the fibular. Hypochondroplasia can be distinguished from other osteochondrodystrophies such as achondroplasia, pseudo-achondroplasia and metaphyseal chondroplasia by the recognition of it clinical and radiographic manifestations.

    Full Text Available Leptospirosis has protean clinical manifestations. The classical presentation of the disease is an acute biphasic febrile illness with or without jaundice. Unusual clinical manifestations may result from involvement of pulmonary, cardiovascular, neural, gastrointestinal, ocular and other systems. Immunological phenomena secondary to antigenic mimicry may also be an important component of many clinical features and may be responsible for reactive arthritis. Leptospirosis in early pregnancy may lead to fetal loss. There are a few reports of leptospirosis in HIV- infected individuals but no generalisation can be made due to paucity of data. It is important to bear in mind that leptospiral illness may be a significant component in cases of dual infections or in simultaneous infections with more than two pathogens.

    Fascioliasis is a food-borne parasitic disease caused by the trematode species Fasciola hepatica, distributed worldwide, and Fasciola gigantica, restricted to given regions of Africa and Asia. This disease in humans shows an increasing importance, which relies on its recent widespread emergence related to climate and global changes and also on its pathogenicity in the invasive, biliary, and advanced chronic phases in the human endemic areas, mainly of developing countries. In spite of the large neurological affection capacity of Fasciola, this important pathogenic aspect of the disease has been pronouncedly overlooked in the past decades and has not even appear within the numerous reviews on the parasitic diseases of the central nervous system. The aim of this wide retrospective review is an in-depth analysis of the characteristics of neurological and ocular fascioliasis caused by these two fasciolid species. The terms of neurofascioliasis and ophthalmofascioliasis are restricted to cases in which the direct affection of the central nervous system or the eye by a migrant ectopic fasciolid fluke is demonstrated by an aetiological diagnosis of recovered flukes after surgery or spontaneous moving-out of the fluke through the orbit. Cases in which the ectopic fluke is not recovered and the symptoms cannot be explained by an indirect affection at distance may also be included in these terms. Neurofascioliasis and ophthalmofascioliasis cases are reviewed and discussed. With regard to fascioliasis infection giving an indirect rise to neurological affection, the distribution and frequency of cases are analysed according to geography, sex, and age. Minor symptoms and major manifestations are discussed. Three main types of cases are distinguished depending on the characteristics of their manifestations: genuine neurological, meningeal, and psychiatric or neuropsychic. The impressive symptoms and signs appearing in each type of these cases are included. Brain examination

    2014-01-01

    This chapter reviews the most common neurologic disorders associated with common vaccines, evaluates the data linking the disorder with the vaccine, and discusses the potential mechanism of disease. A literature search was conducted in PubMed using a combination of the following terms: vaccines, vaccination, immunization, and neurologic complications. Data were also gathered from publications of the American Academy of Pediatrics Committee on Infectious Diseases, the World Health Organization, the US Centers for Disease Control and Prevention, and the Vaccine Adverse Event Reporting System. Neurologic complications of vaccination are rare. Many associations have been asserted without objective data to support a causal relationship. Rarely, patients with a neurologic complication will have a poor outcome. However, most patients recover fully from the neurologic complication. Vaccinations have altered the landscape of infectious disease. However, perception of risk associated with vaccinations has limited the success of disease eradication measures. Neurologic complications can be severe, and can provoke fear in potential vaccines. Evaluating whether there is causal link between neurologic disorders and vaccinations, not just temporal association, is critical to addressing public misperception of risk of vaccination. Among the vaccines available today, the cost-benefit analysis of vaccinations and complications strongly argues in favor of vaccination. © 2014 Elsevier B.V. All rights reserved.

    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.

  8. Quantification In Neurology

    Full Text Available There is a distinct shift of emphasis in clinical neurology in the last few decades. A few years ago, it was just sufficient for a clinician to precisely record history, document signs, establish diagnosis and write prescription. In the present context, there has been a significant intrusion of scientific culture in clinical practice. Several criteria have been proposed, refined and redefined to ascertain accurate diagnosis for many neurological disorders. Introduction of the concept of impairment, disability, handicap and quality of life has added new dimension to the measurement of health and disease and neurological disorders are no exception. "Best guess" treatment modalities are no more accepted and evidence based medicine has become an integral component of medical care. Traditional treatments need validation and new therapies require vigorous trials. Thus, proper quantification in neurology has become essential, both in practice and research methodology in neurology. While this aspect is widely acknowledged, there is a limited access to a comprehensive document pertaining to measurements in neurology. This following description is a critical appraisal of various measurements and also provides certain commonly used rating scales/scores in neurological practice.

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent

    Many of Shakespeare's plays contain characters who appear to be afflicted by neurological or psychiatric disorders. Shakespeare, in his descriptive analysis of his protagonists, was contributing to the understanding of these disorders. In fact, Charcot frequently used Shakespearean references in his neurological teaching sessions, stressing how acute objective insight is essential to achieving expert clinical diagnosis. Charcot found in Shakespeare the same rigorous observational techniques for which he himself became famous. This chapter describes many of Shakespearean characters suffering from varied neurological disorders, including Parkinsonism, epilepsy, sleeping disturbances, dementia, headache, prion disease, and paralyses. © 2013 Elsevier B.V.

  12. VEGF Signaling in Neurological Disorders

    2018-01-01

    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.

    D'Espagnat's proof that the universe is not a 'strongly objective reality' demands that all physical processes are reconsidered in that light. D'Espagnat suggests a 'Veiled Reality' as a suitable alternative. The most economical way to achieve that is to demand that 'information production' at a quantum level creates the basis for self-consistent perception of a world of macroscopic, 'manifest' entities, as opposed to self-existent objects. Such a 'manifest reality' fulfils both Wheeler's attempt at an 'IT-from-BIT' programme, and Zeilinger's suggestion that 'information is primary'.

    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.

    The brain and nervous system are important targets for immune-mediated damage in systemic lupus erythematosus (SLE), resulting in a complex spectrum of neurological syndromes. Defining nervous system disease in lupus poses significant challenges. Among the difficulties to be addressed are a diversity of clinical manifestations and a lack of understanding of their mechanistic basis. However, despite these challenges, progress has been made in the identification of pathways which contribute to neurological disease in SLE. Understanding the molecular pathogenesis of neurological disease in lupus will inform both classification and approaches to clinical trials.

    Eclampsia is one of the most common acute neurological events occurring during pregnancy. However, there are many other conditions that can present during pregnancy and the puerperium and that may either mimic eclampsia or produce other acute neurological manifestations. Frequently the symptoms and signs are non-specific, and it can be difficult to differentiate between these conditions on clinical grounds alone. Neuroradiological studies can provide valuable diagnostic information, and interventional radiological procedures may play a part in the subsequent management of these conditions. This review focuses on the imaging of acute neurological conditions which may be associated with, or present during, pregnancy and the puerperium

    Acromegaly and gigantism are due to excess GH production, usually as a result of a pituitary adenoma. The incidence of acromegaly is 5 cases per million per year and the prevalence is 60 cases per million. Clinical manifestations in each patient depend on the levels of GH and IGF-I, age, tumor size, and the delay in diagnosis. Manifestations of acromegaly are varied and include acral and soft tissue overgrowth, joint pain, diabetes mellitus, hypertension, and heart and respiratory failure. Ac...

    Localized scleroderma en coup de sabre (LScs) is a form of localized scleroderma thought to be an autoimmune disorder. Central nervous system involvement is not rare and neurological manifestations include seizures, focal neurological deficits, headache and neuropsychiatric changes. Patients attending the Neurology Clinic with the final diagnosis of LScs with neurological manifestations were identified and clinical and imagiological records reviewed. Five patients (0.024%) had LScs with neurological involvement, presenting with transient focal neurologic deficits, seizures, headache or migraine with aura. Neuroimaging studies confirmed localized skin depression and showed bone thinning, white matter lesions, brain calcifications, sulcal effacement and meningeal enhancement. Three patients experienced clinical improvement after immunosuppressive therapy, and in two of these patients neuroimaging findings also improved. Recognizing typical dermatologic changes is keystone for the diagnosis of LScs with neurological involvement. It is a diagnosis of exclusion and extensive etiological diagnostic evaluation should be performed. Treatment options, including conservative follow-up or immunosuppressive therapy, should be carefully considered. Copyright © 2016 Elsevier B.V. All rights reserved.

    The process of zeolitization at uranium ore manifestation is studied. A specific type of low-temperature wall endogenous alteration of rocks due to the effect of primary acid solution with low content of carbonic acid is established. Leaching of calcium from enclosing rocks and its deposition in ore-accompanying calcium zeolites is a characteristic feature of wall-metasomatosis. Formation of desmin- calcite-laumontite and quartz-fluoroapatite of vein associations, including ore minerals (uranophane and metaotenite), is genetically connected with calcium metasomatosis. On the basis of the connection of ore minerals with endogeneous process of zeolitization a conclusion can be made on endogenous origin of uranophane and metaotenite [ru

    Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis and transmission is via an airborne route by droplet infection. In the majority of cases patients have thoracic TB, which most frequently presents with hilar lymphadenopathy and pulmonary manifestation. Due to the rise in incidence of TB in central Europe to be expected over the coming years, it is essential to be acquainted with the radiological manifestations of pulmonary TB, particularly to be able to discriminate active from inactive TB. Due to the use of molecular techniques entailing DNA fingerprinting, the traditional classification of TB in primary and postprimary TB is being challenged. These genetic studies have revealed that variations in the clinical and radiographic appearance of TB are mainly affected by the immune status of the patients. Due to the low prevalence of TB in central Europe and the wide variation of radiological presentations, the diagnosis and therapy of TB is often delayed. In this article, the radiographic manifestations of thoracic TB are summarized and discussed. Together with the medical history and bacteriological tests, chest X-ray imaging and computed tomography (CT) play a major role not only in the detection of TB but also in the follow-up during and after therapy. Chest X-radiographs should be the primary diagnostic method in patients with suspected TB in screening as well as for diagnosis and therapy monitoring. The use of CT is more sensitive than chest radiographs and is frequently performed after chest radiographs to obtain detailed information about subtle parenchymal changes or lymph node manifestation. When active TB is suspected CT should be performed. Tree in bud, lobular consolidations, centrilobular nodules, cavities and ground-glass opacification are typical changes in active TB. (orig.)

    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

    Literature complements medical literature in the academic and clinical development of neurologists. The present article explores the contributions of writers of fiction on neurology. Literary works of fiction with particular reference to neurology. A symbiosis between writers of fiction and doctors has been well recognised. From Shakespeare to Cervantes by way of Dickens and Cela to writer - physicians such as Anton Chekhov or António Lobo Antunes have contributed through their medically informed literature to the better understanding of neurology. Some writers like Dostoevsky, Machado de Assis and Margiad Evans have written about their own experiences with disease thus bringing new insights to medicine. Furthermore, some neurological disorders have been largely based on literary descriptions. For instance, Dostoevsky's epilepsy has been retrospectively analysed by famous neurologists including Freud, Alajouanine or Gastaut, whilst his writings and biography have prompted others like Waxman and Geschwind to describe typical behavioural changes in temporal lobe epilepsy, finding their source of inspiration in Dostoevsky. Likewise, Cirignotta et al have named an unusual type of seizure after the Russian novelist. Inspired by Lewis Carroll, Todd introduced the term Alice in Wonderland Syndrome to refer to visual distortions generally associated with migraine. Writers of fiction offer a humanised perception of disease by contributing new insights into the clinical history, informing about the subjective experience of the illness and helping to eradicate the stigma associated to neurological disorders.

  15. Neurologic Complications of Transplantation.

    2018-02-01

    Neurologic disturbances including encephalopathy, seizures, and focal deficits complicate the course 10-30% of patients undergoing organ or stem cell transplantation. While much or this morbidity is multifactorial and often associated with extra-cerebral dysfunction (e.g., graft dysfunction, metabolic derangements), immunosuppressive drugs also contribute significantly. This can either be through direct toxicity (e.g., posterior reversible encephalopathy syndrome from calcineurin inhibitors such as tacrolimus in the acute postoperative period) or by facilitating opportunistic infections in the months after transplantation. Other neurologic syndromes such as akinetic mutism and osmotic demyelination may also occur. While much of this neurologic dysfunction may be reversible if related to metabolic factors or drug toxicity (and the etiology is recognized and reversed), cases of multifocal cerebral infarction, hemorrhage, or infection may have poor outcomes. As transplant patients survive longer, delayed infections (such as progressive multifocal leukoencephalopathy) and post-transplant malignancies are increasingly reported.

    The broad immunologic roles of autophagy span innate and adaptive immunity and are often manifested in inflammatory diseases. The immune effects of autophagy partially overlap with its roles in metabolism and cytoplasmic quality control but typically expand further afield to encompass unique...... immunologic adaptations. One of the best-appreciated manifestations of autophagy is protection against microbial invasion, but this is by no means limited to direct elimination of intracellular pathogens and includes a stratified array of nearly all principal immunologic processes. This Review summarizes...... the broad immunologic roles of autophagy. Furthermore, it uses the autophagic control of Mycobacterium tuberculosis as a paradigm to illustrate the breadth and complexity of the immune effects of autophagy....

    2005-01-01

    Full Text Available Leptospiral uveitis is a common entity in tropical countries. Ocular manifestations are noted in the second phase of illness, but these remain under-diagnosed mainly because of the prolonged symptom-free period that separates the systemic manifestations from detection of ocular manifestations.Varying ophthalmic presentations and the intrinsic nature of different types of uveitis to mimic one another also challenge the accuracy of the diagnosis. Of the individual ocular signs, the combination of acute, non-granulomatous, panuveitis, hypopyon, vasculitis, optic disc edema, membranous vitreous opacities and absence of choroiditis or retinitis have high predictive value for the clinical diagnosis of leptospiral uveitis. Geographic location of the patient, occupation, socio-economic status, risk factors related to exposure, past history of fever or jaundice also aid in diagnosis.Steroids are the mainstay of treatment for leptospiral uveitis. Depending upon the severity and anatomical location of inflammatory lesion, topical, peri-ocular and/or systemic steroids are given. The prognosis is generally good, even when the inflammation is severe.

    This chapter aims to provide an up-to-date review of the science and clinical practice pertaining to neurologic injury after successful cardiopulmonary resuscitation. The past two decades have seen a major shift in the science and practice of cardiopulmonary resuscitation, with a major emphasis on postresuscitation neurologic care. This chapter provides a nuanced and thoughtful historic and bench-to-bedside overview of the neurologic aspects of cardiopulmonary resuscitation. A particular emphasis is made on the anatomy and pathophysiology of hypoxic-ischemic encephalopathy, up-to-date management of survivors of cardiopulmonary resuscitation, and a careful discussion on neurologic outcome prediction. Guidance to practice evidence-based clinical care when able and thoughtful, pragmatic suggestions for care where evidence is lacking are also provided. This chapter serves as both a useful clinical guide and an updated, thorough, and state-of-the-art reference on the topic for advanced students and experienced practitioners in the field. © 2017 Elsevier B.V.

    Thirty-one individuals awaiting trial or sentencing for murder or undergoing an appeal process requested a neurologic examination through legal counsel. We attempted in each instance to obtain EEG, MRI or CT, and neuropsychological testing. Neurologic examination revealed evidence of "frontal" dysfunction in 20 (64.5%). There were symptoms or some other evidence of temporal lobe abnormality in nine (29%). We made a specific neurologic diagnosis in 20 individuals (64.5%), including borderline or full mental retardation (9) and cerebral palsy (2), among others. Neuropsychological testing revealed abnormalities in all subjects tested. There were EEG abnormalities in eight of the 20 subjects tested, consisting mainly of bilateral sharp waves with slowing. There were MRI or CT abnormalities in nine of the 19 subjects tested, consisting primarily of atrophy and white matter changes. Psychiatric diagnoses included paranoid schizophrenia (8), dissociative disorder (4), and depression (9). Virtually all subjects had paranoid ideas and misunderstood social situations. There was a documented history of profound, protracted physical abuse in 26 (83.8%) and of sexual abuse in 10 (32.3%). It is likely that prolonged, severe physical abuse, paranoia, and neurologic brain dysfunction interact to form the matrix of violent behavior.

    There are few studies of HIV-related neurological disorders from centres in low-income countries where facilities are available for detailed investigation. Records of all patients attending the paediatric HIV outpatient department at B. J. Wadia Hospital for Children, Mumbai between April 2000 and March 2008 were reviewed. Of 668 HIV-infected patients, 48 (7.2%) had neurological manifestations and are included in this study. Twenty-six (54.2%) children had HIV encephalopathy. Other causes of neurological manifestations include febrile convulsion in five (10.4%), bacterial meningitis in three (6.3%), epilepsy in two (4.2%), tuberculous meningitis and progressive multi-focal encephalopathy in two (4.2%) each and toxoplasmosis, vasculitis, acute demyelinating encephalomyelitis, anti-phospholipid antibody syndrome, Down's syndrome, birth asphyxia, herpes simplex encephalopathy and mitochondrial encephalopathy in one (2.1%) each. Mean (SD) age at presentation was 4.36 (3.38) years with a range of 2 months to 15 years. The common subtle neurological manifestations were abnormal deep tendon reflexes and extensor plantar reflexes. The common symptomatic manifestations were delayed milestones in 21 children (43.8%) and seizures in 19 (39.6%). Seizures were more common in males (54%) than in females (25%) (p=0.038). In children neurological deficits were more common in older children. Of the 13 children who received HAART, nine (60.23%) improved. Early diagnosis of neurological disorders in HIV-infected children is important for appropriate investigation and management, especially the introduction of HAART.

    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.

  7. The Role of Magnesium in Neurological Disorders

    Directory of Open Access Journals (Sweden)

    Anna E. Kirkland

    2018-06-01

    Full Text Available Magnesium is well known for its diverse actions within the human body. From a neurological standpoint, magnesium plays an essential role in nerve transmission and neuromuscular conduction. It also functions in a protective role against excessive excitation that can lead to neuronal cell death (excitotoxicity, and has been implicated in multiple neurological disorders. Due to these important functions within the nervous system, magnesium is a mineral of intense interest for the potential prevention and treatment of neurological disorders. Current literature is reviewed for migraine, chronic pain, epilepsy, Alzheimer’s, Parkinson’s, and stroke, as well as the commonly comorbid conditions of anxiety and depression. Previous reviews and meta-analyses are used to set the scene for magnesium research across neurological conditions, while current research is reviewed in greater detail to update the literature and demonstrate the progress (or lack thereof in the field. There is strong data to suggest a role for magnesium in migraine and depression, and emerging data to suggest a protective effect of magnesium for chronic pain, anxiety, and stroke. More research is needed on magnesium as an adjunct treatment in epilepsy, and to further clarify its role in Alzheimer’s and Parkinson’s. Overall, the mechanistic attributes of magnesium in neurological diseases connote the macromineral as a potential target for neurological disease prevention and treatment.

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

    Only nine cases of adrenomyeloneuropathy have been reported in the literature. It manifested as adrenal insufficiency, spastic paraparesis, loss of bowel, bladder and sexual functions, and peripheral neuropathy. Our paper describes a patient with the diagnosis of adrenomyeloneuropathy who was admitted to our hospital for rehabilitation. Family and neurological history, physical examination and special laboratory studies such as ACTH stimulation test, electrodiagnostic findings, cystometrogram and sexual function evaluation were essential to establish the diagnosis of this disease. His rehabilitation consisted of bowel and bladder training, ambulation with long-leg braces and crutches, wheelchair mobilization and transfers, and independence of all activities of daily living.

    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.

    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.

    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.

    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.

    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.

    Kapp, H.J.

    1997-01-01

    Rheumatoid arthritis preferrably becomes manifest at the synovial joints of the limbs, especially at the small joints of the hands and feet, at bursae and synovial sheathes. The pathologic lesions are less frequently found at cartilaginous joints or entheses. The lesions very often are symmetrically distributed and are characterized by the following: 1. A periarticular, spindle-shaped opacity with a density similar to soft-tissue, induced by an inflammatory hypertrophy of the synovia, a serosynovitis, or an edematous impregnation of the periarticular tissue. 2. A juxta-articular osteoporosis, most probably caused by a neighbouring synovialitis accompanied by hyperemia. 3. A diffuse joint cavity narrowing due to a destruction of the articular cartilage by the pannus, a fibrovascular resorptive tissue. 4. Central as well as marginal erosions, caused by destruction of ossous material by the pannus. 5. Subchondral signal cysts, likewise unduced by the pannus. (Orig./AJ) [de

    Full Text Available CONTEXT: The incidence of staphylococcal infection has been increasing during the last 20 years. OBJECTIVE: Report a case of staphylococcal endocarditis preceded by musculoskeletal manifestations, which is a rare form of clinical presentation. DESIGN: Case report. CASE REPORT: A 45-year-old-man, without addictions and without known previous cardiopathy, was diagnosed as having definitive acute bacterial endocarditis due to Staphylococcus aureus. Its etiology was community-acquired, arising from a non-apparent primary focus. In addition, the musculoskeletal symptoms preceded the infective endocarditis (IE by about 1 month, which occurred together with other symptoms, e.g. mycotic aneurysms and petechiae. Later, the patient showed perforation of the mitral valve and moderate mitral insufficiency with clinical control.

    Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart disease (ACHD) population. As this group has increased in number and age, emerging science has highlighted the systemic nature of ACHD. Providers caring for these patients are tasked with long-term management of multiple neurologic, pulmonary, hepatic, renal, and endocrine manifestations that arise as syndromic associations with congenital heart defects or as sequelae of primary structural or hemodynamic abnormalities. In this review, we outline the current understanding and recent research into these extra-cardiac manifestations. Copyright © 2016 Elsevier Inc. All rights reserved.

    The variable symptoms and signs of pulmonary vasculitis are a diagnostic and therapeutic challenge. Vasculitis should be considered in rapidly progressing, severe and unusual manifestations of pulmonary disease. Clinical examination of other organ systems typically affected by vasculitis such as skin and kidney and autoantibody measurements are complementary approaches to manage this situation. Pulmonary involvement is common in small vessel vasculitis including anti-GBM disease (Goodpasture syndrome) and the ANCA-associated vasculitides. Life threatening pulmonary hemorrhage and irreversible damage of other organs, frequently the kidney, are important complications necessitating rapid diagnosis of these conditions.Vasculitides are rare diseases of multiple organs and therapies including biologics are evolving rapidly, requiring cooperation of specialities and with specialized centres to achieve best patient care. All involved physicians should be aware of typical complications of immunosuppressive therapy. © Georg Thieme Verlag KG Stuttgart · New York.

    2011-12-01

    The cardiovascular manifestations of alkaptonuria relate to deposition of ochronotic pigment within heart valves, endocardium, aortic intima and coronary arteries. We assessed 16 individuals with alkaptonuria for cardiovascular disease, including full electrocardiographic and echocardiographic assessment. The self reported prevalence of valvular heart disease and coronary artery disease was low. There was a significant burden of previously undiagnosed aortic valve disease, reaching a prevalence of over 40% by the fifth decade of life. The aortic valve disease was found to increase in both prevalence and severity with advancing age. In contrast to previous reports, we did not find a significant burden of mitral valve disease or coronary artery disease. These findings are important for the clinical follow-up of patients with alkaptonuria and suggest a role for echocardiographic surveillance of patients above 40 years old.

    Sans, B; Calvas, P; Bazex, J

    1998-01-01

    Waardenburg syndrome is an uncommon genetic disorder. Four clinical types are recognized. Three responsible genes have been identified (PAX 3: for type I syndrome, MITF and EDN3 for types II and IV respectively). We report the case of a patient with Waardenburg type I morphotype who had atypical neurological manifestations. Decisive elements for diagnosis were the presence of Waardenburg syndrome in the family and, in affected kin, a mutation causing a shift in PAX 3 gene reading. This case confirms the variability of Waardenburg signs within one family. The association of unusual neurological manifestations in the proband suggested that Vogt Koyanagi Harada disease may have been associated and may show some relationship with familial Waardenburg syndrome.

    The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. Systemic autoimmune diseases can affect both the central and peripheral nervous systems in a myriad of ways and through a heterogeneous number of mechanisms leading to many different clinical manifestations. As a result, neurological complications of these disorders can result in significant morbidity and mortality. The most common complication of peripheral nervous system (PNS) involvement ...

    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.

  8. Neurological Consequences of Obesity

    Science.gov (United States)

    O’Brien, Phillipe D.; Hinder, Lucy M.; Callaghan, Brian C.; Feldman, Eva L.

    2017-01-01

    Obesity, primarily a consequence of poor dietary choices and an increased sedentary lifestyle, has become a global pandemic that brings with it enormous medical, social, and economic challenges. Not only does obesity increase the risk of cardiovascular disease and certain cancers, but it is also recognized as a key driver of other metabolic syndrome (MetS) components. These components include insulin resistance, hyperglycemia with prediabetes or type 2 diabetes, dyslipidemia, and hypertension, and are underlying contributors to systemic metabolic dysfunction. More recently, obesity and diet-induced metabolic dysfunction have been identified as risk factors for the development of a wide variety of neurological disorders in both the central and peripheral nervous systems. An abundance of literature has shown that obesity is associated with mild cognitive impairment and altered hippocampal structure and function, and there is a robust correlation between obesity and Alzheimer’s type dementia. Similarly, many reports show that both the autonomic and somatic components of the peripheral nervous system are impacted by obesity. The autonomic nervous system, under control of the hypothalamus, displays altered catabolic and anabolic processes in obese individuals attributed to sympathetic-parasympathetic imbalances. A close association also exists between obesity and polyneuropathy, a complication most commonly found in prediabetic and diabetic patients, and is likely secondary to a combination of obesity-induced dyslipidemia with hyperglycemia. This review will outline the pathophysiological development of obesity and dyslipidemia, discuss the adverse impact of these conditions on the nervous system, and provide evidence for lipotoxicity and metabolic inflammation as the drivers underlying the neurological consequences of obesity. In addition, this review will examine the benefits of lifestyle and surgical interventions in obesity-induced neurological disorders. PMID

    2016-01-01

    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

    @@In 1921, the first independent department of neurology was established in Beijing. Before 1949, all over China only 12 professional doctors lectured neurology in medical colleges. Only 30 medically trained personnel were engaged in the neurological departments. The neurological departments contained roughly 200 beds. The thesis on stroke was written by Zhang Shanlei and published in 1922. Author discussed the cerebral stroke on basis of Chinese traditional medicine and European medicine. The first Textbook of Neurology in China was written by Professor Cheng Yu-lin and was published in 1939. In 1952, the Chinese Society of Neurology and Psychiatry of Chinese Medical Association was established. In 1955, the first issue of the Chinese Journal of Neurology and Psychiatry was published.

    Based upon an analysis of 6 major historical technological advances over the last 150 years, a new syndrome, disruptive technology disorder (DTD), is introduced. DTD describes the human health ailments that accompany the implementation of disruptive technologies. Elevator sickness, railway spine, and bicycle face are representative examples. Though the underlying causative disruptive technologies may differ, many neurologic symptoms (headache, dizziness, weakness) are common to multiple DTDs. Born of technology-driven societal change, DTDs manifest as a complex interplay between biological and psychological symptoms. © 2017 American Academy of Neurology.

    2006-08-01

    Full Text Available Seizures and focal neurologic deficits may be the complications of neurosyphilis, but status epilepticus as a presenting picture of neurosyphilis is rare. We describe a 41-year-old man with an acute onset of expressive dysphasia, followed by persistent seizure state and severe complications of systemic medical problems. An extensive laboratory evaluation confirmed the diagnosis of neurosyphilis and diabetes mellitus. Brain magnetic resonance imaging showed edematous change in the left cingulate gyrus, left temporal lobe, and peri-Rolandic area, which suggested an inflammatory process. Due to varied clinical manifestations of neurosyphilis, we underscore the importance of considering neurosyphilis among the possible causes of status epilepticus and any central nervous system diseases.

    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.

    First described in the early 1980s, antiphospholipid syndrome (APS) is a unique form of acquired autoimmune thrombophilia in which patients present with clinical features of recurrent thrombosis and pregnancy morbidity and persistently test positive for the presence of antiphospholipid antibodies (aPL). At least one clinical (vascular thrombosis or pregnancy morbidity) and one lab-based (positive test result for lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein 1 antibodies) criterion have to be met for a patient to be classified as having APS. However, the clinical spectrum of APS encompasses additional manifestations that can affect many organs and cannot be explained exclusively by patients being in a prothrombotic state; clinical manifestations not listed in the classification criteria (known as extra-criteria manifestations) include neurologic manifestations (chorea, myelitis and migraine), haematologic manifestations (thrombocytopenia and haemolytic anaemia), livedo reticularis, nephropathy and valvular heart disease. Increasingly, research interest has focused on the development of novel assays that might be more specific for APS than the current aPL tests. This Review focuses on the current classification criteria for APS, presenting the role of extra-criteria manifestations and lab-based tests. Diagnostic approaches to difficult cases, including so-called seronegative APS, are also discussed.

    2017-01-01

    Full Text Available Nervous system lesions associated with chronic alcohol intoxication are common in clinical practice. They lead to aggravated alcoholic disease, its more frequent recurrences, and intensified pathological craving for alcohol. Neurological pathology in turn occurs with frequent exacerbations. The interaction of diseases, age, and medical  pathomorphism modifies the clinical presentation and course of the  major pathology, as well as comorbidity, the nature and severity of  complications, worsens quality of life in a patient, and makes the  diagnostic and treatment process difficult. The paper discusses the  classification, clinical variants, biochemical and molecular biological  aspects of various complications of alcoholic disease. It considers its  most common form, in particular alcoholic polyneuropathy, as well as its rarer variants, such as hemorrhagic encephalopathy with a subacute course (Gayet–Wernicke encephalopathy.

    2005-01-01

    The significance of deja vu is widely recognised in the context of temporal lobe epilepsy, and enquiry about deja vu is frequently made in the clinical assessment of patients with possible epilepsy. Deja vu has also been associated with several psychiatric disorders. The historical context of current understanding of deja vu is discussed. The literature reveals deja vu to be a common phenomenon consistent with normality. Several authors have suggested the existence of a "pathological" form of deja vu that differs, qualitatively or quantitatively, from "non-pathological" deja vu. The features of deja vu suggesting neurological or psychiatric pathology are discussed. Several neuroanatomical and psychological models of the deja vu experience are highlighted, implicating the perceptual, mnemonic and affective regions of the lateral temporal cortex, hippocampus and amygdala in the genesis of deja vu. A possible genetic basis for a neurochemical model of deja vu is discussed. Clinical approaches to the patient presenting with possible deja vu are proposed.

    The first African Child Neurology Association meeting identified key challenges that the continent faces to improve the health of children with neurology disorders. The capacity to diagnose common neurologic conditions and rare disorders is lacking. The burden of neurologic disease on the continent is not known, and this lack of knowledge limits the ability to lobby for better health care provision. Inability to practice in resource-limited settings has led to the migration of skilled professionals away from Africa. Referral systems from primary to tertiary are often unpredictable and chaotic. There is a lack of access to reliable supplies of basic neurology treatments such as antiepileptic drugs. Few countries have nationally accepted guidelines either for the management of epilepsy or status epilepticus. There is a great need to develop better training capacity across Africa in the recognition and management of neurologic conditions in children, from primary health care to the subspecialist level.

    In celiac disease (CD), the gut is the typical manifestation site but atypical neurological presentations are thought to occur in 6 to 10% with cerebellar ataxia being the most frequent symptom. Most studies in this field are focused on patients under primary neurological care. To exclude such an observation bias, patients with biopsy proven celiac disease were screened for neurological disease. A total of 72 patients with biopsy proven celiac disease (CD) (mean age 51 +/- 15 years, mean disease duration 8 +/- 11 years) were recruited through advertisements. All participants adhered to a gluten-free diet. Patients were interviewed following a standard questionnaire and examined clinically for neurological symptoms. Medical history revealed neurological disorders such as migraine (28%), carpal tunnel syndrome (20%), vestibular dysfunction (8%), seizures (6%), and myelitis (3%). Interestingly, 35% of patients with CD reported of a history of psychiatric disease including depression, personality changes, or even psychosis. Physical examination yielded stance and gait problems in about one third of patients that could be attributed to afferent ataxia in 26%, vestibular dysfunction in 6%, and cerebellar ataxia in 6%. Other motor features such as basal ganglia symptoms, pyramidal tract signs, tics, and myoclonus were infrequent. 35% of patients with CD showed deep sensory loss and reduced ankle reflexes in 14%. Gait disturbances in CD do not only result from cerebellar ataxia but also from proprioceptive or vestibular impairment. Neurological problems may even develop despite strict adherence to a gluten-free diet. (c) 2009 Movement Disorder Society.

    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.

    2017-01-01

    Abstract Introduction: Neurological involvement is a frequent complication of systemic neoplasm, but not all secondary lesions have clinical manifestations, and there are fewer cases in which first symptom is neurological. Materials and Methods: Retrospective study between January 2006 through November 2016 of patients in whom neurological manifestations due to metastases were the inaugural manifestation of systemic neoplasm. Results: Twenty-six patients (19 male, 7 female) between the ages of 48 and 85 were identified. The main complaints were motor deficit (n = 10), headache (n = 7), behaviour change (n = 3), sensory deficit (n = 2), language disorder (n=1), visual disorder (n=1), syncope (n = 1) and dizziness (n = 1), with 11 patients presenting with symptoms other than the main complaint. Twenty-four patients had brain metastases, in 9 patients, it was solitary, in 5 patients, 2 lesions were found and in the remaining 9, 3 or more lesions were found. Two patients had multiple spinal metastases and 1 patient presented meningeal carcinomatosis. The primary neoplasm were of pulmonary origin (n = 17), gastric (n = 1), prostatic (n = 1), rectal (n = 1) and skin (n=1). In 5 patients the primary lesion remained hidden. Histology results were available in 19 patients: adenocarcinoma (n = 13), small cell carcinoma (n = 3), spinous cell carcinoma (n = 1), melanoma (n = 1) and linitis plastica (n=1). The treatment consisted in corticosteroid treatment (n = 23), chemotherapy (n = 11), radiotherapy (n = 11), surgery (n = 2) and hormonal treatment (n = 1). The mean survival was 225 days, ranging from 9 to 801 days. Conclusions: With this work we verified a broad spectrum of central nervous system symptoms as clinical presentation of malignant neoplasm. In these cases, a detailed investigation is essential for the treatment and prognosis of these patients.

    Sickle cell disease (SCD) is an inherited abnormality of the ss-globin chain, which causes a spectrum of haemolytic anaemias. Clinical manifestations in SCD include anaemia, jaundice, recurrent vaso-occlusive crises, and infections (particularly by encapsulated bacteria) due to functional asplenia and cerebrovascular accidents. Radiological investigations play a critical role both in the diagnosis and in the primary prevention of the complications of SCD

    Sickle cell disease (SCD) is an inherited abnormality of the ss-globin chain, which causes a spectrum of haemolytic anaemias. Clinical manifestations in SCD include anaemia, jaundice, recurrent vaso-occlusive crises, and infections (particularly by encapsulated bacteria) due to functional asplenia and cerebrovascular accidents. Radiological investigations play a critical role both in the diagnosis and in the primary prevention of the complications of SCD.

    Familial Mediterranean fever (FMF) is autoinflammatory disorder characterized by sporadic attacks of fever, peritonitis, pleuritis, and arthritis. It is mainly seen in patients from Mediterranean origins, but it is now reported more frequently in Europe and North America due to immigration. To analyze the data on the cardiovascular manifestations in FMF patients, we searched PubMed using the terms “Familial Mediterranean Fever” or “FMF” in combination with other key words including “cardiovas...

  9. Neurological implications and neuropsychological considerations on folk music and dance.

    Sironi, Vittorio A; Riva, Michele A

    2015-01-01

    Neurological and neuropsychological aspects of folk music and traditional dance have been poorly investigated by historical and scientific literature. Some of these performances could be indeed the manifestation of latent pathological conditions or the expression of liberation rituals. This chapter aimed at analyzing the relationships between traditional dance, folk music, and neurological and psychiatric disorders. Since ancient times, dance has been used in the individual or collective as treatment of some diseases, including epilepsy and movement disorders (dyskinesia, chorea, etc.). Dionysia in Ancient Greece, St. Vitus dance in the Middle Age, tarantism and other traditional dances of southern Italy and of non-Western countries might be credited as curative rituals of these neurological and psychiatric conditions. During the nineteenth century, dance was also used for the treatment of psychiatric patients; the relationship between dance and insanity could also be reflected in classical ballets and music of that period. Nowadays, neuropsychiatric manifestations could also be evidenced in modern dances (mass fainting at rock concerts, flash mobs); some ballroom dances are commonly used for the rehabilitation of patients suffering from neurodegenerative and psychiatric conditions. Interdisciplinary research on these subjects (ethnomusicology and cultural anthropology, clinical neurology and dynamic psychology, neuroradiology and neurophysiology, and socioneurology and neuromusicology) should be increased. © 2015 Elsevier B.V.

    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.

    Half of the adults in the United States use complementary and alternative medicine with mind-body therapy being the most commonly used form. Neurology patients often turn to their physicians for insight into the effectiveness of the therapies and resources to integrate them into their care. The objective of this article is to give a clinical overview of mind-body interventions and their applications in neurology. Medline and PsychInfo were searched on mind-body therapies and neurologic disease search terms for clinical trials and reviews and published evidence was graded. Meditation, relaxation, and breathing techniques, yoga, tai chi, and qigong, hypnosis, and biofeedback are described. Mind-body therapy application to general pain, back and neck pain, carpal tunnel syndrome, headaches, fibromyalgia, multiple sclerosis, epilepsy, muscular dysfunction, stroke, aging, Parkinson disease, stroke, and attention deficit-hyperactivity disorder are reviewed. There are several conditions where the evidence for mind-body therapies is quite strong such as migraine headache. Mind-body therapies for other neurology applications have limited evidence due mostly to small clinical trials and inadequate control groups.

    2016-01-01

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Hereditary neurological disorders (HNDs) are relatively common in children compared to those occurring in adulthood. Recognising clinical manifestations of HNDs is important for the selection of genetic testing, genetic testing results interpretation, and genetic consultation. Meanwhile, advances in next generation sequencing (NGS) technologies have significantly enabled the discovery of genetic causes of HNDs and also challenge paediatricians on applying genetic investigation. Combination of both clinical information and advanced technologies will enhance the genetic test yields in clinical setting. This review summarises the clinical presentations as well as genetic causes of paediatric neurological disorders in four major areas including movement disorders, neuropsychiatric disorders, neuron peripheral disorders and epilepsy. The aim of this review is to help paediatric neurologists not only to see the clinical features but also the complex genetic aspect of HNDs in order to utilise genetic investigation confidently in their clinical practice. A smooth transition from research based to clinical use of comprehensive genetic testing in HNDs in children could be foreseen in the near future while genetic testing, genetic counselling and genetic data interpretation are in place appropriately.

    2012-01-01

    Full Text Available Paraneoplastic neurological syndromes (PNS are rare disorders associated with cancer, not caused by direct invasion, metastasis or consequences of treatment. They are usually autoimmune in nature. Often, PNS precedes the manifestations of cancer. Onconeural antibodies are important in the diagnosis and management of these disorders. These antibodies are specific for the malignancy rather than for a particular neurological syndrome. Often, there are different antibodies associated with the same syndrome. Multiple antibodies are also known to coexist in a given patient with malignancy. While investigating a patient for suspected PNS, the entire gamut of onconeural antibodies should be investigated so as not to miss the diagnosis. In 30-40% of the cases, PNS can occur without antibodies. Investigations for identifying the underlying cancer can be directed by the antibody panel. If conventional screening for cancer is negative, a positron emission scanning/computed tomography scan can be useful. Patients need follow-up surveillance for cancer if not detected in the first instance. Cancer detection and treatment, immunotherapy and supportive care are important components of treatment of PNS. Immunotherapy is very effective in PNS associated with cell membrane-associated antibodies like voltage-gated potassium channel complex, NMDA receptor antibodies and voltage-gated calcium channel antibodies. Immunotherapy includes steroids, IVIgG, plasmaphereis, cytotoxic medications and rituximab. Supportive therapy includes symptomatic treatment with antiepileptic and analgesic medications, physiotherapy, speech therapy and occupational therapy. PNS can mimic any neurologic syndrome. A high index of clinical suspicion is important for early diagnosis and prompt management and better outcome.

    Full Text Available Introduction: Knowledge of etiopathogenesis of post-stroke depressive phenomena contributes to early diagnostics which shortens recovery to a great extent and suits the social and professional rehabilitation of patients, if followed by proper psycho/pharmacotherapy. The aim of this work is to research dependence of depressive manifestations considering the size and anatomical localization of lesion. Subjects and Methods: The research included 118 patients with stroke. Lesion localization was defined on computerized axial tomography records, whereas the area and perimeter of lesion were measured by AutoCAD 2004 software. Examinations by means of Hamilton Rating Scale for Depression were carried out by the method of random selection 11–40 days after stroke. Correlation analysis was made by simple linear/nonlinear regression and Cox’s hazard regression model. Results: Negative correlation was observed between the intensity of depressive manifestations and the size of cerebrovascular lesion (Spearman’s r= – 0.263, P= 0.004. By means of Cox’s regression model we determined 4.389 times higher risk for depression occurrence in female patients (P< 0.001, as well as higher risk due to lobus limbicus structure damages (hazard ratio eb(HR = 2.661, P= 0.019. Conclusion: Lower intensity of depressive manifestations with larger cerebrovascular lesions, we have explained by activation of reparation mechanisms with energy savings and decrease (due to neurological deficits of afferent peripheral sensations which antecedent the occurrence of emotions (James-Lange peripheral theory of emotions.

    Bertorini, Tulio E; Perez, Angel

    2014-01-01

    Disorders of the adrenal glands frequently have secondary neurological manifestations, while some diseases that involve the central nervous system are accompanied by adrenal gland dysfunction. Excessive corticosteroid secretions in primary or secondary Cushing's syndrome causes muscle weakness and behavioral disturbances, such as emotional lability and sometimes depression, while adrenal insufficiency may cause fatigue, weakness, and depression. Adrenoleukodystrophy and adrenoneuromyelopathy are X-linked recessive disorders of the metabolism of very long chain fatty acids that manifest with white matter abnormalities of the brain, myelopathy and/or neuropathy, as well as adrenal insufficiency. Other disorders of the adrenal glands include hyperaldosteroidism, which may cause weakness from hypokalemia. Dysfunction of the adrenal medulla causes excessive or deficient secretion of catecholamines, primarily causing cardiovascular symptoms. This chapter reviews the clinical manifestations and diagnostic aspects and treatment of the various disorders of the adrenal glands. Some of the congenital adrenal diseases are also discussed. © 2014 Elsevier B.V. All rights reserved.

    Neurological complications are a rare but important and significant source of information about morbidity and mortality in liver transplant patients. Based on the clinical and radiological findings of 21 patients, neurological complications were categorized into five main groups; focal hemorrhagic or occlusive complications (n=11); diffuse hypoxic-ischemic injury (n=3); hypertensive encephalopathy (n=1); central pontine or extra-pontine myelinolysis (n=4); and infection (n=2). Neurological manifestations varied according to the location of the lesion, although seizures were the most common manifestation. In this pictorial review, we illustrate the radiological findings, focusing on MR and CT images, of a spectrum of neurological complications following liver transplants, as well as their clinical correlations.

    Hypochrondroplasia is an inherited skeletal dysplasia that resembles achondroplasia in mild degree. Radiographic manifestations encountered in 12 affected individuals in South Africa include slight shortening of all segments of the tubular bones, moderate caudal diminution of the lumbar interpedicular distances, increased lumbar lordosis with cacral tilt and distal prolongation of the fibular. Hypochondroplasia can be distinguished from other osteochondrodystrophies such as achondroplasia, pseudo-achondroplasia and metaphyseal chondroplasia by the recognition of it clinical and radiographic manifestations.

    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.

    2012-01-01

    Acromegaly and gigantism are due to excess GH production, usually as a result of a pituitary adenoma. The incidence of acromegaly is 5 cases per million per year and the prevalence is 60 cases per million. Clinical manifestations in each patient depend on the levels of GH and IGF-I, age, tumor size, and the delay in diagnosis. Manifestations of acromegaly are varied and include acral and soft tissue overgrowth, joint pain, diabetes mellitus, hypertension, and heart and respiratory failure. Acromegaly is a disabling disease that is associated with increased morbidity and reduced life expectancy. The diagnosis is based primarily on clinical features and confirmed by measuring GH levels after oral glucose loading and the estimation of IGF-I. It has been suggested that the rate of mortality in patients with acromegaly is correlated with the degree of control of GH. Adequately treated, the relative mortality risk can be markedly reduced towards normal.

Skin is affected by the acute metabolic derangements as well as by chronic degenerative complications of diabetes. Aims: To evaluate the prevalence of skin manifestations in patients with diabetes mellitus. To analyze the prevalence and pattern of skin disorders among diabetic patients from this region of Western Himalayas. Materials and Methods: One hundred consecutive patients with the diagnosis of diabetes mellitus and having skin lesions, either attending the diabetic clinic or admitted in medical wards were included in this study. Results: The common skin disorders were: x0 erosis (44%, diabetic dermopathy (36%, skin tags (32%, cutaneous infections (31%, and seborrheic keratosis (30%. Conclusion: Skin is involved in diabetes quite often and the manifestations are numerous. High prevalence of xerosis in our diabetic population is perhaps due to cold and dry climatic conditions in the region for most of the time in the year.

    In order to determine the thoracic manifestations of severe ovarian hyperstimulation syndrome, the medical records and available images of 771 patients who had received gonadotropins to induce superovulation, were reviewed. In 22 patients (3%) severe hyperstimulation syndrome was diagnosed clinically and confirmed with ultrasonography (US). Pleural effusion occurred in five of these (23%), one of whom required thoracentesis. Atelectasis and internal jugular vein thrombosis developed in one patient, and ventilation-perfusion mismatch occurred in another. The study concluded that respiratory distress in patients with ovarian hyperstimulation syndrome was most likely due to lung restriction. Pulmonary manifestations formed an important part of this syndrome, and radiologic input were considered necessary for assessment, monitoring and management. 10 refs., 2 figs., 1 tab.

    The Netherlands Society of Neurology evolved from the Society of Psychiatry founded in 1871. The name was changed into Netherlands Society of Psychiatry and Neurology (NSPN) in 1897. In the same year, the word neurology was also added to the name of the journal. The Society steadily blossomed, but in 1909 the first signs of dissatisfaction occurred: the Amsterdam Neurologists Society was founded. A few split-offs would follow. The number of members of the NSPN increased from 205 in 1920 to 585 in 1960. In the early 1960s, the Society was reorganised and would consist of two sections, one for psychiatry and one for neurology. However, this would not last, as a full separation was established in 1974. For several reasons, the name of the journal was changed four times until it assumed its present name in 1974. The 100th volume of CNN was not published, as expected. in 1996, but in 1998, because of two skipped publication years, one during WWII and another in the 1970s. During the last decades of the nineteenth century, teaching of neurology was mostly given within the frame of psychiatry, following the German tradition of 'brainpsychiatry' (organic or biologic psychiatry). The first official chair of psychiatry was founded at Utrecht, 1893 (Winkler). In Amsterdam, private teachers such as Delprat taught 'electro-therapy and nervous diseases' since the 1880s. The first extraordinary chair of neurology and electrotherapy was founded for his successor, Wertheim Salomonson in 1899. The first university clinic for psychiatry and neurology started at the Amsterdam Municipal University, when Winkler became professor of psychiatry and neurology in Amsterdam in 1896. Around the turn of the century, chairs of psychiatry and neurology were also founded in Groningen and Leiden. Separate chairs for neurology and psychiatry appeared in Amsterdam in 1923 and in Utrecht in 1936. Following an initiative of Brouwer, the first neurological university clinic opened its doors in

    Drooling is the inability to retain saliva in the mouth and its progression to the digestive tract, being a common problem in pediatric patients with neurological disorders. Three different treatment options are available. To assess the effectiveness and safety of trihexyphenidyl, scopolamine and botulinum toxin infiltration in the treatment of drooling in children with neurological disorders. This is an open and prospective type study. We include patients treated in the Neurology Service that present excessive drooling, affecting their quality of life, between 2009 and 2013. We enrolled 46 patients in the study. The treatment with oral trihexyphenidyl was indicated in 46, obtaining good result in 15 (32.6%), three with temporary effect and the rest with lasting effect. Three patients presented side effects (6.5%). Four out of 11 (36.36%) patients treated with scopolamine patch had beneficial effects. One was withdrawn due to lack of efficacy and six due to side effects. Twenty-five patients were infiltrated with botulinum toxin, with a significant decrease of drooling in 16 patients (64%) after the first injection. We observed no significant changes in nine patients. Only one out of 25 showed side effects (mild dysphagia). Currently there is not a fully effective therapeutic option for drooling. We recommend starting treatment with trihexyphenidyl. A second option could be the scopolamine patch and botulinum toxin as a third option. Botulinum toxin infiltration in salivary glands is shown as an effective and safe alternative in our study.

    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.

    Full Text Available Moyamoya disease is a rare neurological condition that affects children and adults of all ages. It is characterized by chronic, progressive stenosis of the circle of Willis that ultimately leads to the development of extensive collateral vessels. Presenting symptoms are usually due to cerebral ischemia or hemorrhage. The Japanese term moyamoya (meaning puffy or obscure was coined to describe the characteristic ‘smoke in the air’ appearance of these vessels on cerebral angiography. Moyamoya has the highest recorded incidence in Japan (0.28 per 100,000. In the west it is an extremely rare condition with an overall incidence of (0.086 per 100,000 in the Western United States. Etiology for the most part is unknown; however, genetic susceptibility related to RNF213 gene on chromosome 17q25.3 has been suggested. Moyamoya is being diagnosed more frequently in all races with varying clinical manifestations. Moyamoya disease is a rare progressive neurologic condition characterized by occlusion of the cerebral circulation with extensive collaterals recruitment in children and adults. Distinguished radiological findings confirm the diagnosis. Early recognition and swift institution of therapy is vital in order to minimize neurological deficits. We present the case of a 19-year-old African American female who presented with left-sided parastheia, weakness, and headache for 2 days duration.

  12. Is the Charcot and Bernard case (1883) of loss of visual imagery really based on neurological impairment?

    INTRODUCTION. The Charcot and Bernard case of visual imagery, Monsieur X, is a classic case in the history of neuropsychology. Published in 1883, it has been considered the first case of visual imagery loss due to brain injury. Also in recent times a neurological valence has been given to it. However, the presence of analogous cases of loss of visual imagery in the psychiatric field have led us to hypothesise functional origins rather than organic. METHODS. In order to assess the validity of such an inference, we have compared the symptomatology of Monsieur X with that found in cases of loss of visual mental images, both psychiatric and neurological, presented in literature. RESULTS. The clinical findings show strong assonances of the Monsieur X case with the symptoms manifested over time by the patients with functionally based loss of visual imagery. CONCLUSION. Although Monsieur X's damage was initially interpreted as neurological, reports of similar symptoms in the psychiatric field lead us to postulate a functional cause for his impairment as well.

    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.

    Full Text Available OBJECTIVE: It was to report on Brazilian cases of neurological complications from bariatric surgery. The literature on the subject is scarce. METHOD: Cases attended by neurologists in eight different Brazilian cities were collected and described in the present study. RESULTS: Twenty-six cases were collected in this study. Axonal polyneuropathy was the most frequent neurological complication, but cases of central demyelination, Wernicke syndrome, optical neuritis, radiculits, meralgia paresthetica and compressive neuropathies were also identified. Twenty-one patients (80% had partial or no recovery from the neurological signs and symptoms. CONCLUSION: Bariatric surgery, a procedure that is continuously increasing in popularity, is not free of potential neurological complications that should be clearly presented to the individual undergoing this type of surgery. Although a clear cause-effect relation cannot be established for the present cases, the cumulative literature on the subject makes it important to warn the patient of the potential risks of this procedure.

  16. Neurologic disorder and criminal responsibility.

    Science.gov (United States)

    Yaffe, Gideon

    2013-01-01

    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.

    The mite-borne rickettsial zoonosis scrub typhus is widely prevalent in parts of Southeast and Far East Asia, and northern Australia. The disease is an acute febrile illness, associated with rash and often an eschar, which responds dramatically to treatment with antibiotics. In some cases it results in a serious illness leading to multiple organ involvement and death. The disease manifestations are thought to result from a systemic vasculitis, caused by both direct effects of the organisms as well as an exaggerated immune response, although little is understood about its pathogenesis. A wide spectrum of clinical manifestations, affecting nearly every organ system, have been described with scrub typhus. Some of these manifestations are serious and life threatening. In this systematic review, we summarise the typical and atypical manifestations of scrub typhus reported in the literature. Awareness of these unusual manifestations will hopefully guide clinicians towards diagnosing the condition early, and initiating early appropriate antibiotics and other supportive measures. © The Author 2017.

    To chronicle the history of medicine and neurology in India with a focus on its establishment and evolution. 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). Information was gathered through literature review using PubMed, MD Consult, OVID, primary texts and research at various academic institutions in India. 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 the amount of basic, clinical and epidemiological research being

    2017-01-01

    Full Text Available Primary immunodeficiency diseases (PIDs are a group of rare, chronic disorders with deficient or malfunctioning immune system. It commonly affects the hematopoietic system, with skin the second most affected organ. Skin involvement is observed in half of pediatric PID cases and often precedes the final diagnosis. Skin infections and eczemas are the two most common manifestations in PID.[1] Skin manifestations associated with PIDs can be of infectious and noninfectious causes. Common noninfectious causes are eczema, erythroderma, cutaneous granulomas, dysplasia, vasculitis, and telangiectasia. It is important to be aware of skin manifestations in pediatric patients as early detection of PID may aid in the management of serious immunologic conditions and prevent associated morbidity and mortality.

  7. Clinical manifestations that predict abnormal brain computed tomography (CT in children with minor head injury

    Directory of Open Access Journals (Sweden)

    Nesrin Alharthy

    2015-01-01

    Full Text Available Background: Computed tomography (CT used in pediatric pediatrics brain injury (TBI to ascertain neurological manifestations. Nevertheless, this practice is associated with adverse effects. Reports in the literature suggest incidents of morbidity and mortality in children due to exposure to radiation. Hence, it is found imperative to search for a reliable alternative. Objectives: The aim of this study is to find a reliable clinical alternative to detect an intracranial injury without resorting to the CT. Materials and Methods: Retrospective cross-sectional study was undertaken in patients (1-14 years with blunt head injury and having a Glasgow Coma Scale (GCS of 13-15 who had CT performed on them. Using statistical analysis, the correlation between clinical examination and positive CT manifestation is analyzed for different age-groups and various mechanisms of injury. Results: No statistically significant association between parameteres such as Loss of Consciousness, ′fall′ as mechanism of injury, motor vehicle accidents (MVA, more than two discrete episodes of vomiting and the CT finding of intracranial injury could be noted. Analyzed data have led to believe that GCS of 13 at presentation is the only important clinical predictor of intracranial injury. Conclusion: Retrospective data, small sample size and limited number of factors for assessing clinical manifestation might present constraints on the predictive rule that was derived from this review. Such limitations notwithstanding, the decision to determine which patients should undergo neuroimaging is encouraged to be based on clinical judgments. Further analysis with higher sample sizes may be required to authenticate and validate findings.

    2015-12-01

    Full Text Available Hypothyroid myopathy is observed frequently and the resolution of the clinical manifestations of myopathy following thyroid hormone replacement is well known. However, a specific subtype of hypothyroid myopathy, Hoffmann's syndrome, characterized by increased muscular mass (pseudohypertrophy, proximal muscle weakness, muscle stiffness and cramps, is rarely reported. Herein, we describe a 34-year-old male who presented with proximal muscle weakness and non-pitting edema of the lower extremities. He initially visited the neurology department where he was suspected of having polymyositis. Additional laboratory evaluation revealed profound autoimmune hypothyroidism and elevated muscle enzymes including creatine kinase. The patient was started on levothyroxine treatment and, subsequently, clinical symptoms and biochemical parameters resolved with the treatment. The present case highlights that hypothyroidism should be considered in the differential diagnosis of musculoskeletal symptoms even in the absence of overt manifestations of hypothyroidism. To our knowledge, this is the first case reported in Korea.

    To review the incidence of stroke in patients undergoing CABG and the impact of a preventive strategy adopted at tertiary care unit of cardiac surgery. The data of all patients who underwent isolated CABG (N= 722) from July 2016 to August 2017 at Faisalabad Institute of Cardiology was retrieved for this retrospective study. All operations were done on cardiopulmonary bypass and cold blood cardioplegia. Numeric data was summarized as Mean ± Standard Deviation while categoric variables were summarized into frequency and percentage. Mean age of patients was 53.83±8.8 years. Mean Parsonnet and Logistic EuroScore were 4.3±3.2 and 3.3±0.9 respectively. Forty nine patients (6.78%) had significant carotid artery disease. Mean number of grafts was 2.8±0.82. Diabetes was present in 27.8% patients. Neurological complications were noticed in 14 patients (1.94%) who included 12 permanent paralyses. Further subgroup analysis revealed that 67 patients who were operated by single clamp technique remained free of neurological complications. This is clinically remarkable finding but due to small population size it is statistically non- significant. The incidence of neurological complications can be reduced significantly by adopting the appropriate preventing measures. Use of Single Clamp technique may be the reasons of such a low incidence of stroke in this study.

    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)

    Pulmonary involvement is more common in systemic lupus erythematosus (SLE) than in any other connective tissue disease, and more than half of patients with SLE suffer from respiratory dysfunction during the course of their illness. Although sepsis and renal disease are the most common causes of death in SLE, lung disease is the predominant manifestation and is an indicator of overall prognosis. Respiratory disease may be due to direct involvement of the lung or as a secondary consequence of the effect of the disease on other organ systems.

    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.

    Complications in urinary tract nervous routes due to herpes viruses as VZV and HSV-2 are well known. Acute urinary retention and chronic neuropathic pain are not rare when sacral dermatomes are involved by these viruses. However, an analogous condition has not yet been clearly ascribed to HSV-1 infection. We present a 32-year-old immunocompetent patient with fever, lumbar pain and acute urinary retention who had never had herpetic clinical manifestations. Urodynamic studies diagnosed a neurologic bladder with an absent filling sensation. Cystoscopic assessment revealed the presence of reddened and isolated small mucosal areas in the bladder walls. The search for herpes viruses in plasma and CSF by PCR assay were positive for HSV-1. After treatment with antiviral therapy the disease resolved. Intermittent catheterization was necessary and voiding dysfunction resolved after three weeks by its appearance. Neurological damage to the central nervous system (CNS) and/or PNS due to HSV-1 seems to be the most likely reason. The course of disease was benign and self-remitting.

    Background: Neurologic complications may be the first symptoms of atrial myxomas. Understanding the imaging features of neurologic complications of atrial myxomas can be helpful for the prompt diagnosis. Objective: To identify neuroimaging features for patients with neurologic complications attributed to atrial myxoma. Methods: We retrospectively reviewed the medical records of 103 patients with pathologically confirmed atrial myxoma at Xiangya Hospital from January 2009 to January 2014. The neuroimaging data for patients with neurologic complications were analyzed. Results: Eight patients with atrial myxomas (7.77%) presented with neurologic manifestations, which constituted the initial symptoms for seven patients (87.5%). Neuroimaging showed five cases of cerebral infarctions and three cases of aneurysms. The main patterns of the infarctions were multiplicity (100.0%) and involvement of the middle cerebral artery territory (80.0%). The aneurysms were fusiform in shape, multiple in number (100.0%) and located in the distal middle cerebral artery (100.0%). More specifically, high-density in the vicinity of the aneurysms was observed on CT for two patients (66.7%), and homogenous enhancement surrounding the aneurysms was detected in the enhanced imaging for two patients (66.7%). Conclusion: Neurologic complications secondary to atrial myxoma consist of cerebral infarctions and aneurysms, which show certain characteristic features in neuroimaging. Echocardiography should be performed in patients with multiple cerebral infarctions, and multiple aneurysms, especially when aneurysms are distal in location. More importantly, greater attention should be paid to the imaging changes surrounding the aneurysms when myxomatous aneurysms are suspected and these are going to be the relevant features in our article

The WFTF data also suggest that for most states, the current demand for neurologist services already exceeds the supply, and by 2025 the demand for neurologists will be even higher. This future demand is fueled by the aging of the US population, the higher health care utilization rates of neurologic services, and by a greater number of patients gaining access to the health care system due to the Patient Protection and Affordable Care Act. Uncertainties in health care delivery and patient access exist due to looming concerns about further Medicare reimbursement cuts. This uncertainty is set against a backdrop of Congressional volatility on a variety of issues, including the repeal of the sustainable growth rate for physician reimbursement. The impact of these US health care changes on the neurology workforce, future increasing demands, reimbursement, and alternative health care delivery models including accountable care organizations, nonphysician providers such as nurse practitioners and physician assistants, and teleneurology for both stroke and general neurology are discussed. The data lead to the conclusion that neurologists will need to play an even larger role in caring for the aging US population by 2025. We propose solutions to increase the availability of neurologic services in the future and provide other ways of meeting the anticipated increased demand for neurologic care.

  4. The neurological basis of occupation.

    The purpose of the present paper was to survey the literature about the neurological basis of human activity and its relationship to occupation and health. Activities related to neurological function were organized into three categories: those that activate the brain's reward system; those that promote the relaxation response; and those that preserve cognitive function into old age. The results from the literature review correlating neurological evidence and activities showed that purposeful and meaningful activities could counter the effects of stress-related diseases and reduce the risk for dementia. Specifically, it was found that music, drawing, meditation, reading, arts and crafts, and home repairs, for example, can stimulate the neurogical system and enhance health and well-being, Prospective research studies are needed to examine the effects of purposeful activities on reducing stress and slowing the rate of cognitive decline.

    Full Text Available Zika virus (ZIKV is an emerging flavivirus rapidly spreading throughout the tropical Americas. Aedes mosquitoes is the principal way of transmission of the virus to humans. ZIKV can be spread by transplacental, perinatal, and body fluids. ZIKV infection is often asymptomatic and those with symptoms present minor illness after 3 to 12 days of incubation, characterized by a mild and self-limiting disease with low-grade fever, conjunctivitis, widespread pruritic maculopapular rash, arthralgia and myalgia. ZIKV has been linked to a number of central and peripheral nervous system injuries such as Guillain-Barré syndrome (GBS, transverse myelitis (TM, meningoencephalitis, ophthalmological manifestations, and other neurological complications. Nevertheless, mechanisms of host-pathogen neuro-immune interactions remain incompletely elucidated. This review provides a critical discussion about the possible mechanisms underlying the development of autoimmune neurological conditions associated with Zika virus infection.

    The term hypoparathyroidism refers to a group of disorders in which a relative or absolute deficiency of PTH leads to hypocalcemia and hyperphosphatemia. Was to evaluate clinical symptoms in patients with hypoparathyroidism during normocalcemic period and to try to establish its etiology (electrolyte imbalance, organic central nervous system lesions, coincidence of tetany and epilepsy). The analysis included a group of 14 patients with hypoparathyroidism: 3 boys and 11 girls, aged from 12 months to 31 years (median 16.11 years), with duration of the disease 12 months to 26 years (median 10.9 years). In all the patients, the diagnosis was confirmed based on history, physical examination, results of biochemical and hormonal laboratory tests, radiological and neurological examinations. All the patients were followed by endocrinology specialists. Low phosphorus diet, calcium, magnesium, active vitamin D supplementation and management of other endocrine disorders were employed. In 9 patients, pseudo-hypoparathyrodism was diagnosed; of this number, in 8 children, type Ia Albright syndrome was confirmed. Five patients were diagnosed as true hypoparathyroidism, two girls in this group were found to have autoimmune hypoparathyroidism as a component of the autoimmune polyglandular syndrome type 1, 2 others were diagnosed in infancy as congenital hypoparathyroidism and 1 girl had true hypoparathyroidism as a component of Kearns-Sayre syndrome. Five patients were referred to neurological department with epilepsy suspicion. In the medical history, 9 patients had generalized epileptic seizures, moreover, 1 girl manifested absence attack and balance disturbances. In 3 patients, EEG demonstrated changes typical of generalized seizure activity. In 5 patients on anti-epileptic management, additional calcium and active vitamin D treatment was initiated, allowing for achieving seizure remission. CT of the head and pituitary gland showed calcification foci in the central nervous system

    A cross-sectional observational study was conducted. The aim was to analyze the clinical-functional profile of patients diagnosed with HTLV-1 (human T-lymphotropic virus type 1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in the Amazon region. Reference center for HTLV in the city of Belém, state of Pará, Brazil. Muscle strength, muscle tone, balance and the need for gait assistance among patients with HAM/TSP were evaluated. Among the 82 patients infected with HTLV-1, 27 (10 men and 17 women) were diagnosed with HAM/TSP. No statistically significant difference in muscle tone or strength was found between the lower limbs. Muscle weakness and spasticity were predominant in the proximal lower limbs. Patients with HAM/TSP are at a high risk of falls (P=0.03), and predominantly use either a cane or a crutch on one side as a gait-assistance device (P=0.02). Patients with HAM/TSP exhibit a similar clinical pattern of muscle weakness and spasticity, with a high risk of falls, requiring gait-assistance devices.

    Cushing disease is a relatively rare cause of Cushing syndrome secondary to a hyperfunctioning pituitary adenoma. In addition to signs and symptoms of hypercortisolism, Cushing disease may present with diverse otolaryngic manifestations, which may guide diagnosis and management. We performed a retrospective chart review of patients who were found to have Cushing disease and who underwent transnasal transsphenoidal surgery for pituitary adenomas between January 1, 2007, and July 1, 2014, at a tertiary academic medical center. There were 37 consecutive patients in this series with Cushing disease caused by a pituitary adenoma. Fifteen (41%) patients complained of visual changes. Five (14%) patients suffered from obstructive sleep apnea. Four (11%) patients had thyroid disease. Other symptoms included hearing loss, vertigo, tinnitus, epistaxis, dysphagia, and salivary gland swelling. Although Cushing disease traditionally presents with classic "Cushingoid" systemic features, it also may present with various otolaryngic manifestations. A thorough workup by otolaryngologists is critical in the comprehensive management of these patients.

    Full Text Available Cerebral venous thrombosis (CVT has a wide spectrum of clinical manifestations that may mimic many other neurological disorders and lead to misdiagnoses. Headache is the most common symptom and may be associated with other symptoms or remain isolated. The other frequent manifestations are focal neurological deficits and diffuse encephalopathies with seizures. The key to the diagnosis is the imaging of the occluded vessel or of the intravascular thrombus, by a combination of magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Causes and risk factors include medical, surgical and obstetrical causes of deep vein thrombosis, genetic and acquired prothrombotic disorders, cancer and hematological disorders, inflammatory systemic disorders, pregnancy and puerperium, infections and local causes such as tumors, arteriovenous malformations, trauma, central nervous system infections and local infections. The breakdown of causes differs in different parts of the world. A meta-analysis of the most recent prospectively collected series showed an overall 15% case-fatality or dependency rate. Heparin therapy is the standard therapy at the acute stage, followed by 3-6 months of oral anticoagulation. Patients with isolated intracranial hypertension may require a lumbar puncture to remove cerebrospinal fluid before starting heparin when they develop a papilloedema that may threaten the visual acuity or decompressive hemicraniectomy. Patients who develop seizures should receive antiepileptic drugs. Cerebral venous thrombosis - even pregnancy-related - should not contraindicate future pregnancies. The efficacy and safety of local thrombolysis and decompressive hemicraniectomy should be tested

    Disorders of mineral metabolism may cause neurologic manifestations of the central and peripheral nervous systems. This is because plasma calcium stabilizes excitable membranes in the nerve and muscle tissue, magnesium is predominantly intracellular and is required for activation of many intracellular enzymes, and extracellular magnesium affects synaptic transmission. This chapter reviews abnormalities in electrolytes and minerals which can be associated with several neuromuscular symptoms including neuromuscular irritability, mental status changes, cardiac and smooth muscle changes, etc. © 2014 Elsevier B.V.

    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

    de Frutos González, V; Guerrero Peral, A L

    2011-09-01

    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.

  20. [Neurology of hysteria (conversion disorder)].

    Science.gov (United States)

    Sonoo, Masahiro

    2014-07-01

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

    A possible definition of clinical, educational and organizing aspects of emergency neurology in Italy is reported in this position paper of Emergency Neurology Intersociety Group, created in 2008 among the two neurological Societies in Italy: Società Italiana di Neurologia and Società di Neuroscienze Ospedaliere. The aim of this Group has been the evaluation of the role of neurologist in the emergency setting of Italian hospitals, as well as of the description of different scenarios in which a ward dedicated to a semi-intensive care of neurological emergencies could have a role in the actual organization of academic or general hospitals in our Country. The actual great relevance of neurologist activity in the inpatients treatment, in fact, is actually misleaded as it is the considerable significance of neurological expertise, techniques and support in hospital care pathways also involving neurological manifestations throughout the course of other diseases. Finally, the possible contents of educational programs orienting neurological specialty towards a better comprehension and management of emergency neurological problems either in terms of specific formation or of techniques to be learned by emergency neurologist, are reported as a results of the Consensus Workshop hold in Castiglioncello (LI) in September 12th, 2009.

    Full Text Available HTLV-1 is the causal agent of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP, a disease observed in up to 5% of individuals infected with HTLV-1. However, infected individuals without the disease can present neurological complaints relating to sensory, motor or urinary manifestations. The aim of this study was to investigate the incidence of neurological manifestations among patients with HTLV-1. Method HTLV-1 patients in Salvador, Bahia, Brazil, were enrolled into a cohort study. Results Among 414 subjects, 76 had definite and 87 had possible or probable HAM/TSP at the baseline, whereas 251 subjects had no neurological signs or symptoms. Definite HAM/TSP developed in 5 patients (1.74%. The asymptomatic subjects were selected for analysis. The incidence rate expressed per 1,000 persons-year was calculated. It was 206 for hand numbness, 129 for nocturia and 126 for urinary urgency. In the neurological examination, leg hyperreflexia presented an average incidence rate of 76; leg paraparesis, 52; and Babinski sign, 36. Kaplan-Meyer curves categorized according to gender and proviral load showed that females and patients with proviral load of more than 100,000 copies per 106 peripheral blood mononuclear cells (PBMCs presented higher risk. Conclusion Development of neurological symptoms or signs occurred in up to 30% of asymptomatic subjects during 8 years of follow-up. Female gender and high proviral load were risk factors for neurological disease.

    2014-01-01

    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.

    2014-10-01

    Dengue infection is an important arboviral infection in southeast Asia, especially in India. Neurological manifestations of dengue are increasingly recognized. We report an ischemic stroke due to dengue vasculitis in an 8-year-old child. We present a girl with a short febrile illness followed by episodic severe headache, with gradually progressive hemiparesis and visual impairment. Her brain magnetic resonance imaging revealed multiple infarctions in the anterior and posterior circulation. The magnetic resonance angiogram revealed irregular narrowing of bilateral middle cerebral arteries, right anterior cerebral artery, left posterior cerebral, and bilateral vertebral arteries suggestive of vasculitis. Her dengue serology was strongly positive for immunoglobulin M with 68.9 panbio units. The rest of the evaluation for pediatric stroke was unremarkable. She was treated with intravenous followed by oral corticosteroids and recovered totally with resolution of vasculitis on magnetic resonance angiogram over the next 3 months. This child illustrates possible immune-mediated vasculitis caused by dengue infection which is rather a rare presentation in a child who subsequently recovered well. One should consider dengue in childhood strokes in endemic regions. Copyright © 2014 Elsevier Inc. All rights reserved.

  8. Otorhinolaryngology manifestations secondary to oral sex.

    Science.gov (United States)

    Fernández-López, Claudia; Morales-Angulo, Carmelo

    Over the last few years, oral and pharyngeal signs and symptoms due to oral sex have increased significantly. However, no review articles related to this subject have been found in the medical literature. The objective of our study was to identify otorhinolaryngological manifestations associated with orogenital/oroanal contact, both in adults and children, in the context of consensual sex or sexual abuse. We performed a review of the medical literature on otorhinolaryngological pathology associated with oral sex published in the last 20 years in the PubMed database. Otorhinolaryngological manifestations secondary to oral sex practice in adults can be infectious, tumoral or secondary to trauma. The more common signs and symptoms found in the literature were human papillomavirus infection (above all, condyloma acuminata and papilloma/condyloma), oral or pharyngeal syphilis, gonococcal pharyngitis, herpes simplex virus infection and pharyngitis from Chlamydia trachomatis. The incidence of human papillomavirus -induced oropharyngeal carcinoma has dramatically increased. In children past the neonatal period, the presence of condyloma acuminatus, syphilis, gonorrhoea or palatal ecchymosis (the last one, unless justified by other causes) should make us suspect sexual abuse. Sexual habits have changed in the last decades, resulting in the appearance of otorhinolaryngological pathology that was rarely seen previously. For this reason, it is important for primary care physicians to have knowledge about the subject to perform correct diagnosis and posterior treatment. Some sexual abuse cases in children may also be suspected based on the knowledge of the characteristic oropharyngeal manifestations secondary to them.

    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.

    Systemic diseases affecting the cornea have a wide range of manifestations. The detailed study of all pathologies that cause corneal alteration is unapproachable, so we have centered our interest in the most prevalent or characteristic of them. In this paper we have divided these pathologies in sections to facilitate their study. Pulmonar and conective tissue (like colagen, rheumatologic and idiopathic inflamatory diseases), dermatologic, cardiovascular, hematologic, digestive and hepatopancreatic diseases with corneal alteration are described. Endocrine and metabolic diseases, malnutrition and carential states are also studied, as well as some otorhinolaryngologic and genetic diseases that affect the cornea. Finally, a brief report of ocular toxicity induced by drugs is referred.

    Chronic liver disease is one of the major complications of cystic fibrosis (CF). Significant liver disease is seen in 13-25% of children with CF. Improved life expectancy and prolonged follow-up have favored better characterization of the hepatic manifestations of CF and allowed direct observation of an increasing number of liver-related events. Liver disease typically develops in the first decade of life, with the incidence dropping rapidly after the age of 10 years. The wide spectrum of liver disease ranging from asymptomatic gallbladder abnormalities to biliary cirrhosis will be reviewed in this article

    Norrie disease (ND) is an X-linked recessive disorder characterized by congenital blindness, progressive sensorineural hearing loss and cognitive impairment. The ocular phenotype has been well described, while the extraocular manifestations of the disorder are not well understood. We present the data from the Norrie Disease Registry, which consists of 56 patients with detailed clinical histories and genotype data. This study represents the largest, detailed investigation into the phenotypic spectrum of ND to date and more importantly expands knowledge of the extraocular clinical manifestations. We identify several novel aspects of the syndrome that will improve the management of these patients. In particular, we expand our understanding of the neurologic manifestations in ND and identify a chronic seizure disorder in approximately 10% of all patients. In addition, details of the hearing phenotype are described including the median age of onset (12 years of age) and how genotype affects onset. Moreover, we find vascular disease to be a significant component of ND; and vascular health should be, in the future, a component of patient clinical care. In summary, the results expand our understanding of the phenotypic variability and genotypic heterogeneity in ND patients. Copyright © 2012 Wiley Periodicals, Inc.

    Thirty-two confirmed cases of non -Hodgkin's lymphoma (NHL) were examined for cutaneous manifestations for a period of 2 years from November 1998 in KMC Hospital Attavar, Mangalore. Cutaneous manifestations in the study group were compared to a control group of 32 patients. Specific infiltrates were present in all (5/5) CTCL patients and one out of twenty-seven patients with low grade NHL. Morphologically they presented as papules, plaques, nodules and erythroderma. Infective conditions seen in the study group were superficial fungal (7/32) and viral infections (2/ 32). Non-infective conditions were acquired ichthyosis (10/32), generalised pruritus (5/32), insect bite reaction (1/32) and drug eruption (1/32). When compared to control patients only acquired ichthyosis and generalised pruritus were found to be statistically significant. The study group also showed changes due to chemotherapy like diffuse alopecia (24/29), bluish pigmentation of proximal part of nail (4/29), localised pigmentation of palms and soles (1 /29), diffuse pigmentation at injection site (1 /29), pigmentation at scar site (1 /29) and stomatitis (4/29).

    Several changes in the oral cavity due to chemotherapy can be observed and can lead to important systemic complications, increasing the time of the patient in hospital and the costs of the treatment as well as affect the quality of life of the patients. The aim of this study was to assess the oral manifestation in patients treated with chemotherapy according to sex, age and tumor type. Data was collected in an oncology hospital in Juiz de Fora, Minas Gerais State, from patients' records that were submitted to oncologic treatment. It was possible to verify that mucositis, associated or not to other type of lesions, was the most common lesion in both sex of all ages (15.5%). Xerostomia and other lesions, such as Candida infection and aphthous lesions, were also present. It is possible to improve the quality of life of the patient during and after anti-neoplastic therapies through a protocol of odontological assistance that includes changes of the oral environment previous to chemotherapy such as profilaxis, caries removal, treatment of periodontal and periapical lesions, oral hygiene instructions, diet orientation and laser therapy. It is very important the insertion of the dentist in the oncologic medical team for the early diagnosis of the oral manifestation and follow-up during treatment time.

    Full Text Available Systemic lupus erythematosus (SLE is an inflammatory disease with a wide range of clinical manifestations and complications related to disease activity. One of them is the increase risk to infections secondary to immunological alterations due to pharmacological therapy (especially steroids. Few reports have documented the association of SLE and meningococcal infection with subsequent development of immunological activation (continuous inflammation and intolerance of the immune system. The attempts to make an early and appropriate approach to these type of patients, generate benefits in survival rates and decrease sequelae among those who survive, especially in those in whose infection compromised central nervous system. We present the case of a patient that presented with neurological symptoms compatible with neuroeffector by Neisseria meningitis isolated in CSF cultures. Despite adequate antibiotic treatment the patient continued to deteriorate neurologically, and alternative diagnosis were evaluated after findings of vasculitis in brain CT scan. Immunological panel was performed with positivity of antibodies commonly present in SLE considering that infection by Neisseria meningitis was a trigger of immunological intolerance and development of SLE. We present the following case to understand the physiopathology and relationship between meningococcal infections, complement consumption, immunological intolerance and the development of autoimmune disease.

    We reviewed the files of 80 successive patients with native and prosthetic valve endocarditis admitted to Riyadh Armed Forces Hospital. Neurolological complications (NC) occurred in 28 (35%) patients. The valves involved were mitral in 12 (43%), aortic in eight (29%), combined mitral and aortic lesions in six (21%) and others in two (7%). The common causative organisms were Streptococci in 12 (43%), Staphylococcus aureus and Staphylococcus epidermides, both occurring in four (14%). Compared to the 52 infective endocarditis patients with no neurological complications (NNC), the NC occurred more frequently in male patients, those with aortic valve lesion, those with atrial fibrillation, those with delayed therapy and those with causative organisms being Streptococci or Staphylococci. Eleven patients died (39%), 12 (43%) recovered with motor sequelae, six (21%) had seizure disorder and five (18%) had full recovery. The frequency of neurological complications and mortality is comparable to those reported in the literature: however, the frequency was higher in our patients. (author)

    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.

    With the advent of gray scale ultrasonographic equipment, the parenchymal disease of liver is more easily evaluated. Ultrasonography is a non-invasive technique, different from angiography, and performed without discomfort to patient. And also ultrasonography can be used in assessing the liver in cases showing equivocal scintigraphy and in differentiation of solid and cystic masses, first detected on scintigrams. Therefore, the complementary use of ultrasonography, Tc-99m-sulfur colloid scan and angiography provides better diagnostic accuracy for the detection of hepatocellular carcinoma, and moreover, sequential ultrasonographic studies in the same patient are valuable of following the course of hepatocellular carcinoma and monitoring the effectiveness of therapy for hepatocellular carcinoma. In thirty patients with histologically proven hepatocellular carcinoma, an analysis of ultrasound manifestation is made and the results are as follows; 1. Ultrasound manifestation of hepatocellular carcinoma by gray scale showed four different sonographic patterns including discrete echo free, discrete echogenic, ill defined echogenic and mixed patterns. 2. The size of hepatocellular carcinoma by ultrasonographic measurement was larger than 5 cm in diameter in 28 cases. 3. In 7 cases performed with angiography, all echogenicities of hepatocellualr carcinoma were correlated with the findings of vascularity of angiography. 4. In cases combined with liver cirrhosis, the sonographic pattern of hepatocellular carcinoma appeared to be discrete or ill defined echogenic patterns.

    Full Text Available Introduction: Vestibular schwannoma (also known as acoustic neuroma is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its symptoms are varied, but what stands out most is a unilateral sensorineural hearing loss, with a low index of speech recognition. Objective: Describe an atypical manifestation of vestibular schwannoma. Case Report: The 46-year-old woman had vertigo and binaural hearing loss and fullness, with ear, nose, and throat examination suggestive of cochlear injury. After 6 months, the patient developed worsening of symptoms and onset of right unilateral tinnitus. In further exams the signs of cochlear damage remained, except for the vestibular test (hyporeflexia. Magnetic resonance imaging showed an expansive lesion in the right cerebellopontine angle. Discussion: This report warns about the atypical manifestations of vestibular schwannoma, which must always be remembered in investigating and diagnosing hearing loss.

    2010-02-01

    This review presents the past and the present of pediatric neurology in Poland. Pediatric neurology has its roots in Polish general neurology represented by many outstanding scientists. The founder of Polish school of neurology at the end of 19th century was Edward Flatau, known as the author of Flatau's law. The most famous Polish neurologist was Joseph Babiński, recognized for the first description of pathological plantar reflex. First Polish publication related to child neurology was Brudziński's report on a new meningeal symptom (the flexion of lower limbs during passive neck flexion with pain in neck). Contemporary child neurology in Poland was created by Professor Zofia Majewska after the Second World War. Now 10 academic centers of child neurology exist in Poland fulfilling educational, scientific, and therapeutic roles. Polish Society of Child Neurology was established in 1991 and now there are about 580 members, including 300 child neurologists.

    2017-01-01

    Full Text Available Sickle cell anemia is an inherited hemoglobin disorder characterized by substitution of glutamic acid by valine at the sixth position of the beta globin chain. The sequence of events leads to pain crisis. Ischemia of the tissues resulting from decreased blood flow is believed to occur in pain crisis. Repeated or prolonged sickling causes red cell death in the form of hemolytic anemia. The majority of hospital admissions are due to painful crisis. These patients are at increased risk for both osteomyelitis and infarction of the long bones. Magnetic resonance imaging has been shown to be helpful in the diagnosis of early osteomyelitis and its differentiation from infarction in sickle cell disease patients with acute bone crisis. Others findings include dactylitis, medullary infarcts, diploic space widening, fish mouth vertebrae, and avascular necrosis. We present a case series on the various musculoskeletal manifestations of sickle cell disease.

  12. Neurologic complications of radiation therapy and chemotherapy

    International Nuclear Information System (INIS)

    Rosenfeld, Myrna

    1998-01-01

    Radiation induced toxicities are due to the effect of irradiation of normal surrounding tissue which is included in the radiation port. The mechanisms of radiation induced damage have not been completely elucidated. Hypotheses include direct damage to neural cells versus damage to the vascular endothelium with secondary effects on nervous system structures. Another hypothesis is that radiation damaged glial cells release antigens that are able to evoke and antimmune response against the nervous system resulting in both cellular necrosis and vascular damage. The clinical diagnosis of radiation induced neurotoxicity may be difficult especially in patients who had neurologic signs prior to treatment. It is helpful to determine if the clinical signs correlate with the irradiated site and to know the total dose received and the dose per fraction. Prior or concomitant chemotherapy may act to increase the toxicity produced by radiation. The age of the patient at the time of radiation is important as the very young and the elderly are more likely to develop toxicities. Finally, concurrent neurologic diseases such as demyelinating disorders appear to sensitize neural tissue to radiation damage. Radiation injury can occur at almost any time, from immediately after irradiation to years later. The side effects can generally be divided into those that are acute (within days), early -delayed (within 4 weeks to 4 months after treatment) and late- delayed (months to years after treatment).

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

    2012-04-01

    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.

    The Bible, a major pillar of Western Civilization consists of Hebrew Scriptures, assembled over a millennium and accepted as of divine origin. The Talmud is a compendium of Jewish laws, covering every possible aspect of life, analyzed in depth from 200 BCE to 600 CE, becoming the foundation of Jewish existence. The all-encompassing character of the books provides numerous medical problems and observations that appear in various connotations. When in need to clarify various legal dilemmas, the Talmudic sages displayed astoundingly accurate anatomical knowledge and were pioneers in clinical-pathological correlations. The descriptions of "neurological" events in the Bible are very precise but show no evidence of neurological knowledge. Those reported in the various tractates of the Talmud are evidence of a substantial medical knowledge, marked by Hellenistic influence. Subjects such as head and spinal injuries, epilepsy, handedness neuralgias aphasia tinnitus and tremor were discussed in depth. This chapter is an updated collection of the studies, extracting observations and discussions of neurological manifestations from the ancient texts.

Whilst vascular complications of diabetes are well recognized, and account for principle mortality and morbidity from the condition, musculoskeletal manifestations of diabetes are common and whilst not life threatening, are an important cause of morbidity, pain and disability. Joints affected by diabetes include peripheral joints and the axial skeleton. Charcot neuroarthropathy is an important cause of deformity and amputation associated with peripheral neuropathy. A number of fibrosing conditions of the hands and shoulder are recognized, including carpal tunnel syndrome, adhesive capsulitis, tenosynovitis and limited joint mobility. People with diabetes are more prone to gout and osteoporosis. Management of these conditions requires early recognition and close liaison between diabetes and rheumatology specialists. © The Author 2015.

    Pulmonary vasculitides predominantly involve the small arterioles, capillaries and venules and include Wegener's granulomatosis, microscopic polyangiitis and the Churg-Strauss syndrome. Takayasu's arteriitis is a large vessel disease and may affect the main pulmonary arteries causing stenoses and occlusions. Knowledge of the natural course of disease and of clinical manifestations of pulmonary disease is helpful for an understanding of imaging findings. For this reason this article gives an overview not only of radiologic findings in chest X-ray and high resolution CT of the lungs but as well of clinical aspects of pulmonary vasculitides. Next to determination of disease extension the determination of disease activity is in the foreground of diagnostic imaging in vasculitides. Within this context principals of immunosuppressive therapy will be recognized. (orig.)

    Objective: To study CT findings of hepatic abscess. Methods: CT findings and clinical materials of 38 patients with liver abscess verified by aspiration were retrospectively viewed. All patients were examined by non-enhanced and contrast enhanced CT. Results: In 25 cases, inhomogeneous hypodense lesions with unclear demarcation were found on non-enhanced CT. On contrast enhanced CT scan, target or cluster enhancement was found Additionally, air was found within some lesions. In the rest 13 cases with early stage liver abscess, no typical sign was found on non-enhanced CT, while rosette sign and continued enhancement sign were demonstrated after the contrast agent was given. Conclusion: Various CT findings are found in different stages of liver abscess. The diagnosis and differential diagnosis should be based on CT manifestations and clinical history as well. (authors)

    Full Text Available A study of 36 untreated patients with early syphilis revealed atypical variations namely; long incubation period of 101 days in I patient, more than 3 chancres in 1, undermined margin of the chancre along with tenderness in 1 and moderate to severe tenderness of the ulcers in 2 cases. In 3 patients there was no indurations of the ulcers. Three patients with primary syphilis had unilateral lymphadenitis, and in I case the lymph nodes were not only tender but showed tendency towardsmatingawell. Insecondarysyphilis, 11 out of 16 patients having condylomata lata had no other muco-cutaneous lesions. Concomitant presence of other venereal disease to account for the atypical manifestations was discounted- by appropriate laboratory tests, response to therapeutic agents and follow up.

    Although the diversity of the clinical manifestations of syphilis is well-known, atypical presentations can also occur. Such atypical presentations are associated with a high risk of transmission as a result of diagnostic confusion and treatment delays owing to the disease's ability to mimic other common skin diseases, deviate from classic clinical presentations, and adopt unique forms. Cases of atypical syphilis have been described most frequently in patients with concomitant human immunodeficiency virus (HIV) infection. Because the incidence of syphilis has been growing over recent years -particularly in patients with HIV co-infection- dermatologists need to be familiar with the less well-known clinical presentations of this venereal disease.

    Epilepsy is one of the most disabling symptoms of tuberous sclerosis complex (TSC) and is a leading cause of morbidity and mortality in affected individuals. The relationship between systemic disease manifestations and the presence of epilepsy has not been thoroughly investigated. This study utilizes a multicenter TSC Natural History Database including 1,816 individuals to test the hypothesis that systemic disease manifestations of TSC are associated with epilepsy. Univariate analysis was used to identify patient characteristics (e.g., age, gender, race, and TSC mutation status) associated with the presence of epilepsy. Individual logistic regression models were built to examine the association between epilepsy and each candidate systemic or neurologic disease variable, controlling for the patient characteristics found to be significant on univariate analysis. Finally, a multivariable logistic regression model was constructed, using the variables found to be significant on the individual analyses as well as the patient characteristics that were significant on univariate analysis. Nearly 88% of our cohort had a history of epilepsy. After adjusting for age, gender, and TSC mutation status, multiple systemic disease manifestations including cardiac rhabdomyomas (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.3-3.9, p = 0.002), retinal hamartomas (OR 2.1, CI 1.0-4.3, p = 0.04), renal cysts (OR 2.1, CI 1.3-3.4, p = 0.002), renal angiomyolipomas (OR 3.0, CI 1.8-5.1, p epilepsy. In the multivariable logistic regression model, cardiac rhabdomyomas (OR 1.9, CI 1.0-3.5, p = 0.04) remained significantly associated with the presence of epilepsy. The identification of systemic disease manifestations such as cardiac rhabdomyomas that confer a higher risk of epilepsy development in TSC could contribute to disease prognostication and assist in the identification of individuals who may receive maximal benefit from potentially novel, targeted, preventative therapies.

    Peritoneal metastasis is frequent mode of dissemination of intraabdominal malignancies. Radiologic diagnosis of peritoneal metastasis has relied on indirect evidence on a barium UGI series and small bowel examination. With the advent of CT scanning, CT is capable of direct imaging of peritoneum. The sensitivity of CT in detecting peritoneal metastasis and CT manifestation of peritoneal metastatic lesions had reported occasionally, but rarely in Korea. So, authors illustrated the CT manifestation of peritoneal metastatic lesions in 32 cases of macroscopically proven cases in laparoscopy or laparotomy in Korea University Hae Wha Hospital during recent 4 years. The results are as follows. 1. Of total 32 cases, 18 cases were male and 14 cases were female. Age incidence was the most common in 6th decade. 2. The most common type of malignancy that cause peritoneal metastasis was the stomach cancer and next common type of malignancies were pancreas cancer in men and ovarian cancer in women. 3. Of total 32 cases of peritoneal metastasis which was confirmed by laparoscopy or laparotomy macroscopically, 23 cases (72%) were detected peritoneal thickening and/or omental pathology by CT, and the remaining 9 cases (28%) were not detected by CT. 4. Ascites was present in 19 cases (59%). 5. Parietal peritoneal thickening was present in 16 cases (50%) by CT and sheetlike pattern was the most common findings. The patterns of peritoneal thickening was relatively nonspecific and was not correlated with primary tumor type. 6. Tumor involvement of greater omentum by CT was present in 19 cases (59%). There were 7 cases of smudged appearance pattern, 6 cases of nodular pattern, 6 cases of omental cake pattern and no cystic mass pattern. The patterns of omental pathology was relatively nonspecific and was nor correlated with primary tumor type

    Cases of sprue-like enteropathy associated with olmesartan have sporadically been encountered since it was first reported in 2012, and their most characteristic manifestation is severe diarrhea. We herein report the first case of sprue-like enteropathy manifesting as Wernicke-Korsakoff syndrome due to vitamin B1 malabsorption with only minimally increased bowel movements. When patients are receiving olmesartan and they complain of nonspecific chronic gastrointestinal symptoms, it is important to consider changing the drugs before any serious malabsorption syndrome develops.

    With more of the world's population surviving longer, individuals often face age-related neurology disorders and decline of function that can affect lifestyle and well-being. Despite neurophysiological changes affecting the brain function and structure, the aged brain, in some degree, can learn and relearn due to neuroplasticity. Recent advances in rehabilitation techniques have produced better functional outcomes in age-related neurological conditions. Physical therapy (PT) of the elderly individual focuses in particular on sensory-motor impairments, postural control coordination, and prevention of sarcopenia. Geriatric PT has a significant influence on quality of life, independent living, and life expectancy. However, in many developed and developing countries, the profession of PT is underfunded and understaffed. This article provides a brief overview on (a) age-related disease of central nervous system and (b) the principles, approaches, and doctrines of motor skill learning and point out the most common treatment models that PTs use for neurological patients.

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

    Full Text Available Germline mutations in the RING finger protein gene RNF168 have been identified in a combined immunodeficiency disorder called RIDDLE syndrome. Since only two patients have been described with somewhat different phenotypes, there is need to identify further patients. Here, we report on two Polish siblings with RNF168 deficiency due to homozygosity for a novel frameshift mutation, c.295delG, that was identified through exome sequencing. Both patients presented with immunoglobulin deficiency, telangiectasia, cellular radiosensitivity, and increased alpha-fetoprotein (AFP levels. The younger sibling had a more pronounced neurological and morphological phenotype, and she also carried an ATM gene mutation in the heterozygous state. Immunoblot analyses showed absence of RNF168 protein, whereas ATM levels and function were proficient in lymphoblastoid cells from both patients. Consistent with the absence of RNF168 protein, 53BP1 recruitment to DNA double-strand breaks (DSBs after irradiation was undetectable in lymphoblasts or primary fibroblasts from either of the two patients. γH2AX foci accumulated normally but they disappeared with significant delay, indicating a severe defect in DSB repair. A comparison with the two previously identified patients indicates immunoglobulin deficiency, cellular radiosensitivity, and increased AFP levels as hallmarks of RNF168 deficiency. The variability in its clinical expression despite similar cellular phenotypes suggests that some manifestations of RNF168 deficiency may be modified by additional genetic or epidemiological factors.

    Full Text Available The coexistence of neuronal degeneration, psychiatric manifestation, immune activation and malignant transformation has been documented in literature, suggesting a central dysfunction in the pathophysiology of these disorders. The isoprenoid pathway may be candidate in this respect, in view of the changes in the concentration of some products of this pathway in many of these disorders, however, no detailed study has been carried out in this respect. In view of this, a study was undertaken on the isoprenoid pathway in some of these disorders - primary generalized epilepsy, Parkinson’s disease (PD, schizophrenia, manic depressive psychosis (MDP, CNS glioma, multiple sclerosis, subacute sclerosing panencephalitis (SSPEand a familial group with familial coexistence of schizophrenia, PD, primary generalized epilepsy, malignant neoplasia, rheumatoid arthritis and syndrome-X over three generations. The following parameters were studied in the patients of these disorders as compared to age and sex matched control subjects - ubiquinone dolichol, digoxin, activity of HMG CoA reductase in the plasma and erthyorcyte membrane Na -K--ATpase. Increase in the activity of HMG CoA reductase and in the concentration of plasma digoxin and dolichol was observed in most of these cases. On the other hand, there was decrease in the concentration of plasma ubiquinone. Decrease in the activity of erythrocyte membrane Na-K- ATpase activity for which digoxin is an inhibitor was also observed in all the cases studied. These results indicate an upregulation of the isoprenoid pathway in the neurological and psychiatric disorders studied. The implications of this change is discussed in details.

    Full Text Available Background: The phylum Cnidarians have over nine thousand species that approximately, one hundred species are dangerous for humans. Annually, a large number of deaths were reported due to jellyfish stings. The manifestations depend on their species and kind of venoms, and include the local and systemic manifestations. A number of methods and compounds were used and under investigation for management of injuries with jellyfishes. Due to the lack of an integrated systematic review, the current study was done. Materials and Methods: The PubMed data bank was searched for the term “Jellyfish”. A total of 1677 papers were found. These papers were divided into three categories: medical, biomedical and biotechnological fields. The medical category was further divided into three subcategories comprising systemic manifestations, cutaneous manifestations and treatments for the stings of jellyfishes. The biomedical category was further subdivided into genomics, proteomics, and biology of venoms, mechanisms of actions and products of biomedical significance. In this part of systematic review, the medical aspects of injuries with jellyfishes were evaluated. Results: The clinical manifestations in jellyfish envenomation depend on their species and the nature of venoms. The most common clinical manifestations of jellyfish stings are cutaneous presentations like urticasia, erythema, swelling, vesicles and severe dermonectoric manifestations. Systemic manifestations were seen in the stings of box jellyfishes, Portuguese man-of-war and in Irukandji syndrome. The most common recommendations for jellyfish envenomation managements include decreasing the local effects of venom, prevention of the venomous nematocysts release, and Controlling of systemic reactions. Application of commercial vinegar (4 - 6% acetic acid, hot water immersion (HWI (42 ° C for 20 minutes, ice packs, sea water rinsing for inactivating nematocysts, administration of topical and parenteral

    Streptococcus suis is a bacterium causing a disease in pigs and rarely in humans. This zoonosis is mostly found as a sporadic disease in individuals that were in contact with the affected or infected pigs: farmers, veterinarians and workers engaged in fresh pork processing. It is assumed that the bacterium enters the body through a cut abrasion in the skin. Initially, the condition resembles a flu, followed by signs of bacteriemia and sepsis. The most frequent clinical manifestation of Streptococcus suis infection is meningitis, leading to hearing loss in over 75% of patients, and subsequent arthritis, endophtalmitis, endocarditis and pneumonia. Toxic shock syndrome with hemorhagic manifestations rarely develops. This study included five male patients aged 22 to 63 years treated in the Intensive Care Unit of the Institute of Infectious and Tropical Diseases in Belgrade, due to Streptococcus suis infection. The aim of this study was to point to the existence of this bacteria in our environment, to describe clinical manifestations of the disease and to point out the importance of its prevention. All patients had epidemiological evidence of being in contact with pork meat. There were no data about diseased pigs. The estimated incubation period was 4 to 8 days. All patients had meningeal signs. Clinical symptoms included shivering, fever, vomiting, headache, malaise, vertigo and tinitus. Three patients presented with alerterd level of awarrness. Four patients developed very severe bilateral hearing impairment, whereas one endophtalmtis and one developed endocarditis. The cerebrospinal fluid (CSF) was opalescent in four patients, and only one patient presented with clear CSF. CSF examination showed typical changes characteristic for bacterial meningitis. Streptoccocus suis was isolated in CSF in all patients, and in one patient the bacteria was isolated in blood as well. All patients underwent treatement with II and III generation cephalosporins and one with one

    Radiological findings of 87 cases of intestinal tuberculosis are analyzed and presented. The diagnosis was based on histopathology in 29 cases, and on clinical ground and radiological findings in 58 cases. The radio of male and female patients was 4:6, and peak incidence is between 10 and 30. Abdominal pain, diarrhea, weight loss, fever and general weakness are frequent symptoms, and tenderness of abdomen, ascites with abdominal distension, malnutrition and emaciation are frequent signs of the patients. Laboratory investigation reveal anemia, raised ESR, hypoalbuminaemia and positive occult blood reaction in the stool in most of the patients. Chest film show activity pulmonary tuberculosis in only 1/3 patients. There is no pathognomonic radiological findings in intestinal tuberculosis and their manifestations are protean, and differentiation from other inflammatory diseases and malignant tumors in gastrointestinal tract is very difficult on radiological ground alone. However, in patients with complaining vague abdominal symptoms and signs, the radiological diagnosis is most certain means in the decision of existence of organic lesion and suggestion of tuberculosis in the gastrointestinal tract and its extent as yet. Multiplicity of the lesion, involvement of adjacent organ such as peritoneum or mesenteric lymph nodes, typical nodularity or irregularity of mesenteric border and existence of active pulmonary tuberculosis are the suggestive findings of intestinal tuberculosis. In the diagnosis of inflammatory disease or malignant tumor of gastrointestinal tract, the possibility of tuberculosis should be borne in mind, and vice versa

    Objective: To assess the CT manifestations and diagnostic value in the pancreatic tuberculosis(PTB)with review of the literatures. Methods: All cases of PTB proved by surgery or biopsy were examined with plain and enhanced CT scans. Results: The CT findings in one case with multiple-nodular type of PTB were diffuse enlargement of the pancreas with multiple, nodular, and low-density lesions; The nodular lesions had peripheral enhancement. 7 cases of local type of PTB encroached on pancreatic head. 4 cases showed local soft tissue masses with multiple flecked calcifications in 2 cases and mild enhancement in one case; Cystic masses was found in 2 cases, with mural calcification in 1 case and multi-loculated cystic mass in 1 case, respectively; Massive pancreatic head calcification was demonstrated in one case. In these 8 cases of PTB, the lesion extended out of pancreas in 4 cases, including abdominal tuberculous lymph nodes, tuberculous peritonitis, and hepatosplenic tuberculosis. Conclusion: CT findings of PTB were various but had some characteristics. Pancreatic masses with multiple flecked calcification or mild enhancement could suggest the diagnosis. Abdominal tuberculosis accompanied with the pancreatic lesion, especially tuberculous lymph nodes, was highly suggestive of the diagnosis of PTB

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component

    Full Text Available BACKGROUND AND AIMS: Human immunodeficiency virus (HIV is associated with various mucocutaneous features, which may be the first pointer towards the existence of HIV infection. This study was done to note the different mucocutaneous lesions present in the HIV population in eastern India. METHODS: Four hundred and ten HIV seropositive patients attending the outpatient and inpatient departments were included in the study. RESULTS: Out of 410 HIV positives, 40% had mucocutaneous involvement at presentation. The mean age of the study population was 29 years and male to female ratio was 2.5:1. The common mucocutaneous morbidities included oral candidiasis (36%, dermatophytosis and gingivitis (13% each, herpes zoster (6%, herpes simplex and scabies (5% each. A striking feature, noted in 36% males, was straightening of hairs. Genital herpes was the commonest genital ulcer disease. Lesions associated with declining immunity included oral candidiasis, oral hairy leukoplakia and herpes zoster with median CD4 counts of 98, 62 and 198/ L respectively. CONCLUSION: Early recognition of mucocutaneous manifestations and associated STDs help in better management of HIV/AIDS.

    2011-09-01

    Celiac disease (CD) may often be associated with various motor disorders affecting the different segments of the digestive tract, including the esophagus. Although it has not been universally reported, some available evidences indicate that pediatric and adult celiac patients could manifest a higher frequency of esophagitis and gastroesophageal reflux disease-related symptoms compared to nonceliac patients. In addition, several published studies have consistently shown the efficacy of a gluten-free diet in rapidly controlling esophageal symptoms and in preventing their recurrence. Since the participation of gluten in the esophageal symptoms of CD seems clear, its intimate mechanisms have yet to be elucidated, and several hypothesis have been proposed, including the specific immune alterations characterizing CD, the reduction in nutrient absorption determining the arrival of intact gluten to distal gastrointestinal segments, and various dysregulations in the function of gastrointestinal hormones and peptides. Recent studies have suggested the existence of a possible relationship between CD and eosinophilic esophagitis, which should be more deeply investigated. © 2011 Copyright the Author.

    Vertically transmitted HIV infection is a major problem in the developing world due to the poor availability of antiretroviral agents to pregnant women. HIV is a neurotrophic virus and causes devastating neurological insults to the immature brain. The effects of the virus are further compounded by the opportunistic infections and neoplasms that occur as a result of the associated immune suppression. This review focuses on the imaging features of HIV infection and its complications in the central nervous system. (orig.)

    Inherited ichthyoses are rare disorders in terms of patient numbers, but abundant in terms of clinical-genetic subtypes. These disorders are often associated with severe systemic manifestations, in addition to significant medical, cosmetic and social problems. There are 17 subtypes of syndromic ichthyosis identified so far and most patients with these syndromes are living in countries with high consanguinity rates. Frequently, clinicians cannot make a definitive diagnosis and patients are not managed properly owing to the rarity and complexity of these disorders. These difficulties make this group of ichthyosis and the patients living with them 'orphan'. After skin and skin appendages, nervous system is the most frequently involved system in ichthyosis syndromes. Thus, association of ichthyosis with neurological symptoms provides an important clue for diagnosis. In this article, we aim to increase clinicians' comprehension of ichthyosis syndromes by providing a symptomatology-based approach based on this observation. Additionally, we provide a review of ichthyosis syndromes, with special emphasis on neurological symptoms, hoping to attract interest to this complicated field. © 2016 John Wiley & Sons A/S.

    To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p AIDS. In this study, anterior segment and external ocular manifestations occurred more frequently than posterior segment manifestations. Also, the mean CD4+ count was significantly lower in patients with posterior segment ocular manifestations versus anterior segment ocular manifestations. We found that CD4+ count and age >35 years were independent risk factors for developing ocular manifestations.

    Full Text Available Background: Celiac disease can have extra gastrointestinal tract (GIT presentations, most of which are endocrine. The aim of this study was to present patients diagnosed to have celiac disease from an endocrine department and to study the prevalence of endocrinopathies in celiac disease. Materials and Methods: A total of 36 patients from the endocrinology department (LLRM Medical College, Meerut between January 2011 and July 2012 and who were diagnosed to have celiac disease were included in the study. Results: Short stature was the commonest presentation (25%, other presentations included short stature and delayed puberty (20%, delayed puberty (11%, screening for celiac disease in type-1 DM patients (17%, rickets (6%, anemia not responding to oral therapy (6%, type-1 DM with recurrent hypoglycaemia (6%, and osteomalacia (3%. The endocrine manifestations include (after complete evaluation short stature (58%, delayed puberty (31%, elevated alkaline phospahatase (67%, low calcium (22%, X-rays suggestive of osteomalacia or rickets (8%, capopedal spasm (6%, and night blindness (6%. Anti-TPO antibody positivity was found in 53%, hypothyroidism in 28%, subclinical hypothyroidism in 17%, and type-1 DM in 25% of the patients. A total of 14% patients had no GI symptoms. Conclusion: Celiac disease is an endocrine disrupter as well as the great masquerader having varied presentations including short stature, delayed puberty, and rickets. Some patients who have celiac disease may not have any GI symptoms, making the diagnosis all the more difficult. Also, there is significant incidence of celiac disease with hypothyroidism and type-1 DM, making screening for it important in these diseases.

    Full Text Available Background: The aim of this study was to evaluate and compare the clinical and electrocardiographic (ECG manifestations of benzodiazepines (BZs. Methods: In this retrospective study, all BZ-poisoned patients hospitalized at Loghman Hakim Hospital between September 2010 and March 2011 were evaluated. Patients’ information including age, sex, time elapsed between the ingestion and presentation, and type of the BZ used were extracted from the patients' charts and recorded. ECGs on presentation to the emergency department (ED were evaluated and parameters such as PR interval, QRS duration, corrected QT, amplitude of S wave in lead I, height of R wave and R/S ratio in the lead aVR were also measured and recorded. Results: Oxazepam, chlordiazepoxide, lorazepam, alprazolam, diazepam, and clonazepam were ingested by 9 (3%, 13 (4.4%, 29 (9.9%, 105 (35.8%, 65 (22.2%, and 72 (24.6% patients, respectively. Mean PR interval was reported to be 0.16 ± 0.03 sec and PR interval of greater than 200 msec was detected in 12 (4.5% patients. Mean QRS duration was 0.07 ± 0.01sec and QRS≥120 msec was observed in 7 (2.6% cases. Conclusion: Diazepam is the only BZ that does not cause QRS widening and oxazepam is the only one not causing PR prolongation. It can be concluded that if a patient refers with a decreased level of consciousness and accompanying signs of BZ toxicity, QRS widening in ECG rules out diazepam, whereas PR prolongation rules out oxazepam toxicity.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

    The exploration of brain epigenomes, which consist of various types of DNA methylation and covalent histone modifications, is providing new and unprecedented insights into the mechanisms of neural development, neurological disease and aging. Traditionally, chromatin defects in the brain were considered static lesions of early development that occurred in the context of rare genetic syndromes, but it is now clear that mutations and maladaptations of the epigenetic machinery cover a much wider continuum that includes adult-onset neurodegenerative disease. Here, we describe how recent advances in neuroepigenetics have contributed to an improved mechanistic understanding of developmental and degenerative brain disorders, and we discuss how they could influence the development of future therapies for these conditions.

    A variety of neurological problems have affected the lives of giants in the jazz genre. Cole Porter courageously remained prolific after severe leg injuries secondary to an equestrian accident, until he succumbed to osteomyelitis, amputations, depression, and phantom limb pain. George Gershwin resisted explanations for uncinate seizures and personality change and herniated from a right temporal lobe brain tumor, which was a benign cystic glioma. Thelonious Monk had erratic moods, reflected in his pianism, and was ultimately mute and withdrawn, succumbing to cerebrovascular events. Charlie Parker dealt with mood lability and drug dependence, the latter emanating from analgesics following an accident, and ultimately lived as hard as he played his famous bebop saxophone lines and arpeggios. Charles Mingus hummed his last compositions into a tape recorder as he died with motor neuron disease. Bud Powell had severe posttraumatic headaches after being struck by a police stick defending Thelonious Monk during a Harlem club raid.

    2018-04-01

    Paraneoplastic neurological syndromes (PNS) are caused by immune responses against neuronal antigens expressed by the tumor. Based on the immunological pathomechanisms and responsiveness of treatments, onconeuronal antibodies are divided into two categories: 1) antibodies against neural intracellular antigens and 2) antibodies against neuronal surface or synaptic antigens. The recent discovery of onconeuronal antibodies have radically changed concepts of CNS autoimmunity, including PNS. The recognition of PNS provides a foundation for the early detection of underlying tumors and initiations of prompt treatments, which can result in substantial improvement. We here review the characteristic onconeuronal antibodies, including anti-Hu, anti-Ma2, and anti-N-methyl-D-aspartate receptor, and discuss the algorithm for the diagnosis of PNS.

    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.

It is due to lack of expression of the UBE3A gene, an imprinted gene located on chromosome 15q. Here we review the main features of this phenotype, characterized by happy demeanor with prominent smiling, poorly specific laughing and general exuberance, associated with hypermotor behavior, stereotypies, and reduced behavioral adaptive skills despite proactive social contact. All these phenotypic characteristics are currently difficult to quantify and have been subject to some differences in interpretation. For example, prevalence of autistic disorder is still debated. Many of these features may occur in other syndromic or nonsyndromic forms of severe intellectual disability, but their combination, with particularly prominent laughter and smiling may be specific of Angelman syndrome. Management of problematic behaviors is primarily based on behavioral approaches, though psychoactive medication (eg, neuroleptics or antidepressants may be required.Keywords: Angelman syndrome, UBE3A, chromosome 15, behavioral phenotypes, autism, neurogenetics

    Patients with stroke can experience neurological deterioration in the prehospital setting. We evaluated patients with stroke to determine factors associated with prehospital neurological deterioration (PND). Among the Greater Cincinnati/Northern Kentucky region (population ~1.3 million), we screened all 15 local hospitals' admissions from 2010 for acute stroke and included patients aged ≥20. The GCS was compared between emergency medical services (EMS) arrival and hospital arrival, with decrease ≥2 points considered PND. Data obtained retrospectively included demographics, medical history and medication use, stroke subtype (eg, ischaemic stroke (IS), intracerebral haemorrhage (ICH), subarachnoid haemorrhage (SAH)) and IS subtype (eg, small vessel, large vessel, cardioembolic), seizure at onset, time intervals between symptom onset, EMS arrival and hospital arrival, EMS level of training, and blood pressure and serum glucose on EMS arrival. Of 2708 total patients who had a stroke, 1092 patients (median (IQR) age 74 (61-83) years; 56% women; 21% black) were analysed. PND occurred in 129 cases (12%), including 9% of IS, 24% of ICH and 16% of SAH. In multivariable analysis, black race, atrial fibrillation, haemorrhagic subtype and ALS level of transport were associated with PND. Haemorrhage and atrial fibrillation is associated with PND in stroke, and further investigation is needed to establish whether PND can be predicted. Further studies are also needed to assess whether preferential transport of patients with deterioration to hospitals equipped with higher levels of care is beneficial, identify why race is associated with deterioration and to test therapies targeting PND. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To assess the neurological involvement and outcome, including school and professional performances, of adults and children with cryopyrin-associated periodic syndrome (CAPS). In this observational study, patients with genetically proven CAPS and followed in the national referral centre for autoinflammatory diseases at Bicêtre hospital were assessed. Neurological manifestations, CSF data and MRI results at diagnosis and during follow-up were analyzed. Twenty-four patients (15 adults and 9 children at diagnosis) with CAPS were included. The median age at disease onset was 0 year (birth) [range 0-14], the median age at diagnosis was 20 years [range 0-53] and the mean duration of follow-up was 10.4 ± 2 years. Neurological involvement at diagnosis, mostly headaches and hearing loss, was noted in 17 patients (71%). Two patients of the same family had abnormal brain MRI. A439V mutation is frequently associated with a non-neurological phenotype while R260W mutation tends to be associated with neurological involvement. Eleven adult patients (61%) and 3 children (50%) underwent school difficulties. Neurological involvement is frequent in patients with CAPS and the majority of patients presented difficulties in school performances with consequences in the professional outcome during adulthood. Further studies in larger cohorts of children with CAPS focusing in intellectual efficiency and school performances are necessary.

    Dental assistants help the dentist in preparing material for filling teeth. Amalgam was the filling material mostly commonly used in Norway before 1980, and declined to about 5% of all fillings in 2005. Amalgam is usually an alloy of silver, copper, tin and mercury. Copper amalgam, giving particularly high exposure to mercury was used in Norway until 1994. Metallic mercury is neurotoxic. Few studies of the health of dental assistants exist, despite their exposure to mercury. There are questions about the existence of possible chronic neurological symptoms today within this working group, due to this exposure. The aim of this study was to compare the occurrence of neurological symptoms among dental assistants likely to be exposed to mercury from work with dental filling material, compared to similar health personnel with no such exposure. All dental assistants still at work and born before 1970 registered in the archives of a trade union in Hordaland county of Norway were invited to participate (response rate 68%, n = 41), as well as a similar number of randomly selected assistant nurses (response rate 87%, n = 64) in the same age group. The participants completed a self-administered, mailed questionnaire, with questions about demographic variables, life-style factors, musculoskeletal, neurological and psychosomatic symptoms (Euroquest). The dental assistants reported significant higher occurrence of neurological symptoms; psychosomatic symptoms, problems with memory, concentration, fatigue and sleep disturbance, but not for mood. This was found by analyses of variance, adjusting for age, education, alcohol consumption, smoking and personality traits. For each specific neurological symptom, adjusted logistic regression analyses were performed, showing that these symptoms were mainly from arms, hands, legs and balance organs. There is a possibility that the higher occurrence of neurological symptoms among the dental assistants may be related to their previous work

    A novel H1N1 influenza A virus (A(H1N1)pdm09) particularly affected individuals central nervous system complications associated with pandemic influenza in the pediatric population. Retrospective review of patients with laboratory-confirmed influenza A(H1N1)pdm09 infection and central nervous system manifestations at Texas Children's Hospital between April 2009 and June 2010. Among 365 patients with influenza A(H1N1)pdm09, 32 (8.8%) had central nervous system manifestations at a median age of 4 years. Eight (25.0%) were previously healthy, and 12 (37.5%) had neurological pre-existing conditions. Of the 32 cases of influenza with neurological complications, seizure (n = 17; 53.1%) was the most common central nervous system manifestation, followed by encephalitis (n = 4; 12.5%), meningitis (n = 4; 12.5%), encephalopathy (n = 3; 9.4%), meningismus (n = 3; 9.4%), focal hemorrhagic brain lesions (n = 2; 6.3%), brain infarction (n = 1; 3.1%), and sensorineural hearing loss (n = 1; 3.1%). Two patients demonstrated two or more types of central nervous system complications. One patient had abnormal cerebrospinal fluid with pleocytosis. Almost two thirds of the children with central nervous system manifestations required intensive care unit admission and nearly half required mechanical ventilation. There were no deaths. Patients with pre-existing neurological conditions were at greater risk for central nervous system manifestations during pandemic influenza infection. Patients with central nervous system manifestations were more likely to experience severe illness, characterized by intensive care unit admission and mechanical ventilation, although overall outcomes were good. Influenza prevention in patients with underlying medical conditions, particularly those with neurological conditions, is important. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Sporadic inclusion body myositis (sIBM usually manifests with painless weakness of the hand, finger and hip flexors. Absence of symptoms or signs, but mild hyper-CK-emia as the sole manifestation of IBM, has not been reported. We report the case of a 73-year-old male who presented with asymptomatic recurrent hyper-CK-emia ranging from 200 to 1324 U/L (n<171 U/L, since 10 years. Clinical neurologic investigation, nerve conduction studies and EMG were non-informative. Muscle biopsy surprisingly revealed sIBM. sIBM may be asymptomatic and may manifest with hyper-CK-emia exclusively. So, it has to be included in the differential diagnoses of asymptomatic hyper-CK-emia.

    Objective To determine the type and frequency of neurological signs and symptoms in individuals with fibromyalgia (FM). Methods Persons with FM (n=166) and pain-free controls (n=66) underwent systematic neurological examination by a neurologist blinded to disease status. Neurological symptoms present over the preceding 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurological symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Results Compared to the control group, age and gender adjusted estimates revealed the FM group had significantly more neurological abnormalities in multiple categories including: cranial nerves IX and X (42% vs. 8%), sensory (65% vs. 25%), motor (33% vs. 3%), and gait (28% vs. 7%). Similarly, the FM group endorsed significantly more neurological symptoms than the control group in 27 of 29 categories with the biggest differences observed for photophobia (70% vs. 6%), poor balance (63% vs. 4%), and weakness (58% vs. 2%) and tingling (54% vs. 4%) in the arms and legs. Poor balance, coordination, tingling, weakness in the arms and legs, and numbness in any part of body correlated with appropriate neurological exam findings in the FM group. Conclusions This blinded, controlled study demonstrated neurological physical examination findings in persons with FM. The FM group had more neurological symptoms than controls, with moderate correlation between symptoms and signs. These findings have implications for the medical work-up of patients with FM.

    Full Text Available AIM: To analyze the characteristics of neurological ophthalmology manifestation of patients with neurosyphilis.METHODS: Retrospective and nonrandomized case analysis were used. Totally 22 cases of 39 eyes were included. They were 17 males and 5 females, aged from 34 to 65 years old. The average age were 49.6 years old. RESULTS: The optic nerve atrophy presented in 11 cases of 22 eyes. One eye of them accompanied by left eye oculomotor nerve palsy; 5 eyes in 3 cases expressed as optic neuritis acute phase; neuroretinitis appeared in 4 cases of 6 eyes; 1 case of 2 eyes expressed as chorioretinitis accompanied by optic disc edema; central retinal artery occlusion were found in 1 case of 1 eye. Argyll-Robertson pupil was as only manifestation in 2 cases of 3 eyes. In all cases, Argyll-Robertson pupil signs can be seen in 19 eyes. Treponema pallidum particle agglutination test(TPPAwere positive in all 22 cases. Syphilis rapid plasma reactin test(RPRwere positive in 19 of 21 cases. All patients underwent lumbar puncture and cerebrospinal fluid were detected for RPR, cerebrospinal fluid protein, white blood cell count. Cerebrospinal fluid RPR were positive in 13 cases. Cerebrospinal fluid protein were greater than 450mg/L in 18 cases. Cerebrospinal fluid white blood cell count were greater than 5/mm3 in 13 cases. CONCLUSION: Neurosyphilis involving neuro-ophthalmology often occurs in middle-aged men and subacute onset. Both eyes can suffered from optic nerve disease simultaneously or sequencely. A few can be expressed as other cranial nerve palsy, which may lead to misdiagnosis. Considering medical history, clinical manifestations, ophthalmic examination, serum and cerebrospinal fluid laboratory tests can improve the diagnostic rate.

    Full Text Available Varicella-zoster virus (VZV meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    2012-01-01

    Full Text Available Canine distemper is a highly contagious viral disease caused by the canine distemper virus (CDV, which is a member of the Morbillivirus genus, Paramyxoviridae family. Animals that most commonly suffer from this disease belong to the Canidae family; however, the spectrum of natural hosts for CDV also includes several other families of the order Carnivora. The infectious disease presents worldwide distribution and maintains a high incidence and high levels of lethality, despite the availability of effective vaccines, and no specific treatment. CDV infection in dogs is characterized by the presentation of systemic and/or neurological courses, and viral persistence in some organs, including the central nervous system (CNS and lymphoid tissues. An elucidation of the pathogenic mechanisms involved in canine distemper disease will lead to a better understanding of the injuries and clinical manifestations caused by CDV. Ultimately, further insight about this disease will enable the improvement of diagnostic methods as well as therapeutic studies.

    Full Text Available Autism spectrum disorders in children are attracting the increasing attention of general practitioners, which is due to the specification of diagnostic criteria and to the recognition of the fact that there is atypical autism that is a syndrome of many different diseases. The authors consider in detail the theory of autism and the clinical manifestations of atypical autism, including possible neurological and somatic disorders. Individual attention is placed on the association of autistic disorder with epilepsy or epileptiform activity on the electroencephalogram. An emphasis is made on the need for an interdisciplinary approach and on the interaction of clinicians of different specialties when treating patients with autistic disorder.

    2013-01-01

    Full Text Available Disabling pansclerotic morphea (DPM of childhood is a rare generalized type of localized scleroderma (LS that is known to follow an aggressive course with pansclerotic lesions leading to severe joint contractures and consequent immobility. Mortality is due to complications of the disease such as bronchopneumonia, sepsis, or gangrene. There is no specific laboratory finding. Treatment protocols are still evolving for this severe recalcitrant disorder. Extracutaneous manifestations are rarely reported in DPM. We present the case of a 7-year-old girl with DPM with severe extracutaneous manifestations in the form of gastrointestinal and vascular disease, whose disease progressed rapidly. In spite of treatment with methotrexate, corticosteroids, and PUVA therapy, she ultimately succumbed to her illness due to sepsis.

    Full Text Available We present a case of an incidental diagnosis of panhypopituitarism in a 68-year-old African American man admitted to our psychiatric inpatient unit with symptoms suggestive of schizophrenia. The case was unusual as a first-episode psychosis given the patient’s age. In the course of his admission, the patient’s clinical condition deteriorated culminating in a sudden altered mental status which prompted a transfer to the medical floors and further investigations. A head CT scan and a pituitary MRI revealed a near total resection of the pituitary while laboratory investigations revealed hyponatremia and a grossly low hormone profile. The progression of these events casts doubts on our admitting diagnosis as the primary cause of the patient’s symptoms. The patient’s clinical condition improved only when his endocrinopathy was treated with hormone replacement, fluids, and electrolyte correction in addition to antipsychotics. An inability to verify the patient’s psychiatric history and a remote history of pituitary resection several decades earlier, unknown to the treating team, added to the diagnostic conundrum. We revised the diagnosis to neuropsychiatric manifestations secondary to an organic brain syndrome due to a partial pituitary resection. The patient was discharged with no symptoms of psychosis, good insight, judgment, and good reality testing.

    2011-08-01

    Hemoglobinopathies are among the most common inherited diseases around the world. They have become much more common recently in northern and central Europe, including Germany, due to immigration. Selective review of the literature with consideration of national guidelines. The hemoglobinopathies encompass all genetic diseases of hemoglobin. They fall into two main groups: thalassemia syndromes and structural hemoglobin variants (abnormal hemoglobins). α- and β-thalassemia are the main types of thalassemia; the main structural hemoglobin variants are HbS, HbE and HbC. There are many subtypes and combined types in each group. The highly variable clinical manifestations of the hemoglobinopathies range from mild hypochromic anemia to moderate hematological disease to severe, lifelong, transfusion-dependent anemia with multiorgan involvement. Stem-cell transplantation is the preferred treatment for the severe forms of thalassemia. Supportive, rather than curative, treatment consists of periodic blood transfusions for life, combined with iron chelation. Drugs to treat the symptoms of sickle-cell disease include analgesics, antibiotics, ACE inhibitors and hydroxyurea. Blood transfusions should be given only when strictly indicated. More than 90% of patients currently survive into adulthood. Optimally treated patients have a projected life span of 50 to 60 years. Hemoglobinopathies are a public health issue in today's multiethnic German population. Adequate care of the affected patients requires a wide variety of diagnostic and therapeutic measures.

    To evaluate the impact of brain MRI and single-photon emission computed tomography (SPECT) in early detection of central nervous system abnormalities in patients affected by Wilson's disease (WD) with or without neurological involvement. Out of 25 consecutive WD patients, 13 showed hepatic involvement, ten hepatic and neurological manifestations, and twp hepatic, neurological, and psychiatric symptoms, including mainly movement disorders, major depression, and psychosis. Twenty-four healthy, age-gender matched subjects served as controls. All patients underwent brain MRI and 99m Tc-ethyl-cysteinate dimer (ECD) SPECT before starting specific therapy. Voxel-by-voxel analyses were performed using statistical parametric mapping to compare differences in 99m Tc-ECD brain uptake between the two groups. Brain MRI showed T2-weighted hyperintensities in seven patients (28%), six of whom were affected by hepatic and neurological forms. Brain perfusion SPECT showed pathological data in 19 patients (76%), revealing diffuse or focal hypoperfusion in superior frontal (Brodmann area (BA) 6), prefrontal (BA 9), parietal (BA 40), and occipital (BA 18, BA 39) cortices in temporal gyri (BA 37, BA 21) and in caudatus and putamen. Moreover, hepatic involvement was detected in nine subjects; eight presented both hepatic and neurological signs, while two exhibited WD-correlated hepatic, neurological, and psychiatric alterations. All but one patient with abnormal MRI matched with abnormal ECD SPECT. Pathologic MRI findings were obtained in six out of ten patients with hepatic and neurological involvement while abnormal ECD SPECT was revealed in eight patients. Both patients with hepatic, neurological, and psychiatric involvement displayed abnormal ECD SPECT and one displayed an altered MRI. These findings suggest that ECD SPECT might be useful in detecting early brain damage in WD, not only in the perspective of assessing and treating motor impairment but also in evaluating better the

Therefore, children with neurological pathology on the background of undifferentiated connective tissue dysplasia have a deeper down-the vegetative, the severity of which correlates with the degree of NDCT (P<0.05. The prevalence parasympathicotonia and low sympathetic reactivity in children with UDCT, perhaps due to metabolic disorders: increased average potassium-calcium ratio, which serves as one of the criteria the predominance of vagotonia, and lower levels of total calcium and inorganic phosphorus, which point to insufficient provision of vitamin D. Inadequate functioning of the sympathetic division of ANS leads to decrease of adaptive&trophic processes in situations requiring intense mental activity, and hence the adaptive capacity of the organism. Patients with insufficient vegetative support amid NDCT form a group of psychological risk, which is characterized by reduced subjective assessment of their own capabilities, emotional instability, and repressive conformism.

    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. © 2014 American Academy of Neurology.

    Full Text Available Afaf El-Ansary, Nouf Al-Afaleg, Yousra Al-YafaeeBiochemistry Department, Science College, King Saud University, Riyadh, Saudi ArabiaAbstract: Biomarkers are pharmacological and physiological measurements or specific biochemicals in the body that have a particular molecular feature that makes them useful for measuring the progress of disease or the effects of treatment. Due to the complexity of neurological disorders, it is very difficult to have perfect markers. Brain diseases require plenty of markers to reflect the metabolic impairment of different brain cells. The recent introduction of the metabolomic approach helps the study of neurological diseases based on profiling a multitude of biochemical components related to brain metabolism. This review is a trial to elucidate the possibility to use this approach to identify plasma metabolic markers related to neurological disorders. Previous trials using different metabolomic analyses including nuclear magnetic resonance spectroscopy, gas chromatography combined with mass spectrometry, liquid chromatography combined with mass spectrometry, and capillary electrophoresis will be traced.Keywords: metabolic biomarkers, neurological disorders. metabolome, nuclear magnetic resonance, mass spectrometry, chromatography

    Rosai-Dorfman Disease (RDD), also known as Sinus Histiocytosis with Massive Lymphadenopathy (SHML), is a rare monocyte/macrophage proliferative disorder of varied biological behavior. Although cutaneous and lymph node involvement are relatively well-described, intrathoracic manifestations of RDD have only occasionally been reported. We conducted a retrospective computer-assisted search of the Mayo Clinic record from 1976 to 2005 for patients with histopathologic evidence of RDD on organ biopsy. Clinical characteristics were abstracted from charts and thoracic manifestations recorded. Survival was estimated using the national social security database. A total of 21 patients were diagnosed with RDD over a period of 30 years; 9 had intrathoracic manifestations (43%). Main pulmonary symptoms included dyspnea and cough. Age at the time of diagnosis, gender, race, smoking history, mortality and time of survival after diagnosis were no different between RDD patients with and without intrathoracic manifestations. The most common radiographic thoracic manifestation was mediastinal lymphadenopathy (6 patients). Cystic change, interstitial lung disease, and airway disease were radiographically evident in 4 patients. Seven patients were treated at some point in the course of their disease, most commonly with oral corticosteroids. At the time of last follow-up 87% were alive, with a median (IQR) time interval since diagnosis of 8 years (4-9.7). Intrathoracic manifestations of RDD are relatively common and include mediastinal lymphadenopathy, airway disease, pleural effusion, cystic and interstitial lung disease. Although limited in size, this series suggests the prognosis of patients with RDD and intrathoracic manifestations is relatively good.

    Lyme disease (Lyme borreliosis) is a systemic infectious disease that can present in a variety of clinical manifestations. The disease is caused by a group of spirochaetes--Borrelia burgdorferi sensu lato or Lyme borrelia--that are transmitted to humans by the bite of Ixodes ticks. Lyme disease is the most common arthropode-borne infectious disease in many European countries including Germany. Early localized infection is typically manifested by an erythema migrans skin lesion, in rarer cases as a borrelial lymphocytoma. The most common early disseminated manifestation is (early) neuroborreliosis. In adults, neuroborreliosis appears typically as meningoradiculoneuritis. Neuroborreliosis in children, however, is typically manifested by meningitis. In addition, multiple erythema migrans lesions and Lyme carditis occur relatively frequently. The most common manifestation oflate Lyme disease is Lyme arthritis. Early manifestations (and usually also late manifestations) of Lyme disease can be treated successfully by application of suitable antibacterial agents. For the treatment of Lyme disease, doxycycline, certain penicillins such as amoxicillin and some cephalosporins (ceftriaxone, cefotaxime, cefuroxime axetil) are recommended in current guidelines. A major challenge is the treatment of chronic, non-specific disorders, i. e., posttreatment Lyme disease syndrome and "chronic Lyme disease". Prevention of Lyme disease is mainly accomplished by protecting against tick bites. Prophylactic administration of doxycycline after tick bites is generally not recommended in Germany. There is no vaccine available for human beings.

    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.

Multiple causes for the development of malnutrition in patients with neurological diseases are known including oropharyngeal dysphagia, impaired consciousness, perception deficits, cognitive dysfunction, and increased needs. The present evidence- and consensus-based guideline addresses clinical questions on best medical nutrition therapy in patients with neurological diseases. Among them, management of oropharyngeal dysphagia plays a pivotal role. The guideline has been written by a multidisciplinary team and offers 88 recommendations for use in clinical practice for amyotrophic lateral sclerosis, Parkinson's disease, stroke and multiple sclerosis.

    Paraneoplastic neurological diseases (PND) are rare, but potentially treatable disorders. Paraneoplastic encephalitis is rapidly emerging as an important but likely under-recognized condition in children. The aim of this study was to assess the prevalence and spectrum of PND in children with benign ovary tumor and the long-term outcome. We retrospectively reviewed the charts of all female patients below 18years of age diagnosed with a benign ovarian tumor proven by pathology between January 1993 and December 2010. All the clinical symptoms developed within 5years of tumor diagnosis and the related investigations were recorded. There were total 133 children and adolescents with benign ovarian tumors, mostly mature teratoma. Six patients (4.5%) had neuropsychiatric manifestations and all but one were beyond age 10years. The most common neuropsychiatric presentations were depression or low mood (84%), headache (50%), mutism (50%), hypoventilation (50%), seizures (30%), hallucination (30%), vomiting and hypersalivation (30%). Three patients (2.2%) had serious PND including acute disseminated encephalomyelitis in 1 and anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis in 2. Although all of three improved after tumor removal, one without immunotherapy had neurological sequelae and prolonged ICU stay. The prevalence of PND in benign ovary tumor is not so uncommon in children. It is important to survey ovary tumors in female adolescents with subacute presentation of multiple-level involvement of neuraxis where no clear alternate diagnosis is possible. Treatment of serious PND associated with ovary tumors should include immunotherapy in addition to tumor removal. Copyright © 2013 The Japanese Society of Child Neurology. Published by Elsevier B.V.

    Full Text Available Star fruit (Avarrhoa carambola is a fruit from oxalidace family. lt is found in many countries of the world including Bangladesh. But its ingestion or drinking star fruit juice may lead to intoxication especially in patients with chronic kidney disease and manifestations might be neurological or nephrological. lt may also cause acute kidney injury in patients with previously normal renal function. Here we are presenting a case who presented with acute kidney injury after star fruit ingestion with previously unknown renal function impairment. The etiology was confirmed by histopathological exami­nation after doing renal biopsy. This renal function impairment is mainly due to oxalate crystal induce nephropathy which is richly abundant in star fruit. His renal function was improved ·with conservative management. Physicians should be alert to consider the ingestion of star fruit as a cause of acute kidney injury in a patient even in the absence of previous renal function impairment.

    2000-11-01

    Drug abuse is associated with a variety of neurological complications. The use of certain recreational drugs shows a marked temporal association with the onset of both haemorrhagic and ischaemic strokes, the majority of which develop within minutes to 1 h after the administration of the index drug. Delayed onset of stroke has also been observed. Acute, severe elevation of blood pressure, cardiac dysrhythmias, cerebral vasospasm, vasculitis, embolization due to infective endocarditis or dilated cardiomyopathy, embolization due to foreign material injected with the diluents under non-sterile conditions and 'street drug' contaminants with cardiovascular effects have been suggested as possible underlying mechanisms. Rupture of aneurysms and arteriovenous malformations have been detected in up to half of the patients with haemorrhagic stroke due to cocaine abuse. The less common findings reported have included a mycotic cerebrovascular aneurysm in a patient with infective endocarditis and haemorrhagic stroke. In addition to stroke, cocaine seems to provoke vascular headache. Seizures precipitated by recreational drug abuse are usually caused by acute intoxication in contrast to the withdrawal seizures encountered in subjects with alcohol abuse. Movement disorders and cerebral atrophy correlating with the duration of abuse have been described. Snorting of organic solvents may cause encephalopathy. Cases of spongiform leukoencephalopathy in heroin addicts have also been reported. Peripheral neuropathy is occasionally precipitated by drug poisoning after intravenous administration. Impurities of the drug, risky administration techniques, and the use of mixtures of various drugs, frequently with simultaneous alcohol drinking, should be taken into account when assessing the background of the adverse event as well as the overall lifestyle of the addicted subjects.

    To investigate changes in volume and characteristics of new patients referred when a private pediatric neurology practice (PP) opened in 2004 in an area served primarily by an academic medical center's (AMC) pediatric neurology practice. Retrospective analysis of medical and billing records to examine changes in volume, diagnosis, and sociodemographic factors of new patients at the AMC from July 2004 to June 2005; the PP during the same period; and the AMC during the year before. One year after the PP opened, 40% more new pediatric neurology patients were seen in this area than the year before. Compared with the AMC, PP saw a greater proportion of seizures (34% vs 26%, P 20 miles from the practice (32% vs 64%, P pediatric neurology patients in this area. After the PP opened, the AMC continued to care for most patients with rare diseases and fewer financial resources. Future research should examine whether the increase in volume reflects relief of pent-up demand or increased referral rates due to eased access, and should elucidate how differences in patient populations at academic and private subspecialty practices relate to access to subspecialty care and financial well-being of academic practices.

  9. Unstable mutations: cause of some neurological hereditary diseases

    International Nuclear Information System (INIS)

    Cuenca Berger, P.; Morales Montero, F.

    1999-01-01

    Unstable mutations or amplification of triplets constitute a kind of genetic alteration discovered during the last decade. They had been found inside or near genes important for the normal neurological function of the human being. In some cases, the presence of the amplification causes the inactivation of the gene or the synthesis of a new product which functions different from the original protein. Some common characteristics of diseases caused by the amplification of triplets are that it affects the nervous system and are degenerative in nature. The expression of the manifestations varies according to age. Most of them show genetic anticipation in which the severity of the manifestations increases with each generation and appear at an earlier age. In most cases, the severity of the symptoms is correlated positively to the size of the amplification. The diagnosis of an affected individual in a family may indicate the presence of an altered gene in other relatives. These relatives may not present evident signs of the illness either because it is of late onset or because they carry premutations. The molecular diagnosis of these mutations is important to estimate the risk of developing the disease and/or of transmitting the illness to the descendants and to eliminate the fears of healthy relatives who have inherited normal copies of the gene.

    2016-01-01

    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.

    To discuss the neurological basis of facial recognition, we present our case reports of impaired recognition and a review of previous literature. First, we present a case of infarction and discuss prosopagnosia, which has had a large impact on face recognition research. From a study of patient symptoms, we assume that prosopagnosia may be caused by unilateral right occipitotemporal lesion and right cerebral dominance of facial recognition. Further, circumscribed lesion and degenerative disease may also cause progressive prosopagnosia. Apperceptive prosopagnosia is observed in patients with posterior cortical atrophy (PCA), pathologically considered as Alzheimer's disease, and associative prosopagnosia in frontotemporal lobar degeneration (FTLD). Second, we discuss face recognition as part of communication. Patients with Parkinson disease show social cognitive impairments, such as difficulty in facial expression recognition and deficits in theory of mind as detected by the reading the mind in the eyes test. Pathological and functional imaging studies indicate that social cognitive impairment in Parkinson disease is possibly related to damages in the amygdalae and surrounding limbic system. The social cognitive deficits can be observed in the early stages of Parkinson disease, and even in the prodromal stage, for example, patients with rapid eye movement (REM) sleep behavior disorder (RBD) show impairment in facial expression recognition. Further, patients with myotonic dystrophy type 1 (DM 1), which is a multisystem disease that mainly affects the muscles, show social cognitive impairment similar to that of Parkinson disease. Our previous study showed that facial expression recognition impairment of DM 1 patients is associated with lesion in the amygdalae and insulae. Our study results indicate that behaviors and personality traits in DM 1 patients, which are revealed by social cognitive impairment, are attributable to dysfunction of the limbic system.

    To establish the correlation between the frequency and severity of hypoxic CNS lesions in preterm children with neuropathy and improve the early diagnosis of lesions of the brain structures based on clinical ophthalmologic results. The authors examined 712 premature infants with body mass neurological examination and neurosonography were performed. RP was found in 367 (51.5%) children. In 255 children, the disease regressed naturally. One hundred and twelve (15.7%) children, underwent laser coagulation of the avascular retina due to the severity of RP. Signs of intraventricular hemorrhages (IVH) were noted in 434 (61%) children in the neonatal period. IVH were found in 285 (77.6%) children with RP. RP with the regression after laser coagulation was combined with IVH in 98% of cases, with the higher frequency (55.3%) of IVH, 3 rd degree. Periventricular leucomalation (PVL) was found in 10% of children without RP, in 22.3% of children with RP with naturally regression and in 51,7% of children with RP with laser coagulation of the retina. In 70 children, neurosonographic signs of ischemia of the head of caudate nucleus were identified on the 14-15 th days of life. In this group, RP developed in 54 (77%) children, 27 (38.5%) children needed laser coagulation of the retina. The correlation found between the severity of RP and hypoxic CNS lesions in highly preterm infants might allow the prognosis of visual and neurosomatic disturbances in the early age and timely effective rehabilitation.

    The scope of clinical and laboratory manifestations of the antiphospholipid syndrome (APS) has increased dramatically since its discovery in 1983, where any organ system can be involved. Musculoskeletal complications are consistently reported in APS patients, not only causing morbidity and mortality, but also affecting their quality of life. We reviewed all English papers on APS involvement in the musculoskeletal system using Google Scholar and Pubmed; all reports are summarized in a table in this review. The spectrum of manifestations includes arthralgia/arthritis, avascular necrosis of bone, bone marrow necrosis, complex regional pain syndrome type-1, muscle infarction, non-traumatic fractures, and osteoporosis. Some of these manifestations were reported in good quality studies, some of which showed an association between aPL-positivity and the occurrence of these manifestations, while others were merely described in case reports. © The Author(s) 2016.

    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.

    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

  20. Chapter 44: history of neurology in Italy.

    Science.gov (United States)

    Bentivoglio, Marina; Mazzarello, Paolo

    2010-01-01

    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.

  3. Cochleovestibular Manifestations in Fabry Disease

    Directory of Open Access Journals (Sweden)

    Alberto Ciceran MD

    2016-09-01

    Full Text Available Fabry disease is a rare, X-linked lysosomal storage disorder resulting from deficient α-galactosidase A activity and globotriaosylceramide accumulation throughout the body. This accumulation leads to various clinical disorders, including inner ear lesions, with sensorineural hearing loss and dizziness. Although hearing loss is recognized in these patients, its incidence and natural history have not been characterized. Hearing disorders develop mainly in adulthood, and tinnitus may be an earlier symptom in Fabry disease. A significant incidence of mid- and high-frequency sensorineural hearing loss in affected males is commonly reported, whereas in female carriers, it is much less frequent. In addition, a high incidence of vestibular disorders with dizziness and chronic instability is also observed in these patients. The few studies about the effects of enzyme replacement therapy (ERT on cochleovestibular symptoms show controversial results. Based on the model of densely stained material accumulation in the inner ear, stria vascularis cell, and organ damage, an early indication of ERT may prevent hearing loss due to the reduction in substrate accumulation.

    To determine the type and frequency of neurologic signs and symptoms in individuals with fibromyalgia (FM). Persons with FM (n = 166) and pain-free controls (n = 66) underwent systematic neurologic examination by a neurologist blinded to disease status. Neurologic symptoms lasting at least 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurologic symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Age- and sex-adjusted estimates revealed that compared with the control group, the FM group had significantly more neurologic abnormalities in multiple categories, including greater dysfunction in cranial nerves IX and X (42% versus 8%) and more sensory (65% versus 25%), motor (33% versus 3%), and gait (28% versus 7%) abnormalities. Similarly, the FM group had significantly more neurologic symptoms than the control group in 27 of 29 categories, with the greatest differences observed for photophobia (70% versus 6%), poor balance (63% versus 4%), and weakness (58% versus 2%) and tingling (54% versus 4%) in the arms or legs. Poor balance or coordination, tingling or weakness in the arms or legs, and numbness in any part of the body correlated with appropriate neurologic examination findings in the FM group. This blinded, controlled study demonstrated neurologic physical examination findings in persons with FM. The FM group had more neurologic symptoms than did the controls, with moderate correlation between symptoms and signs. These findings have implications for the medical evaluation of patients with FM.

    Full Text Available Huntington's disease (HD is an inherited neurodegenerative disorder typified by involuntary body movements, and psychiatric and cognitive abnormalities. Many HD patients also exhibit metabolic changes including progressive weight loss and appetite dysfunction. Here we have investigated metabolic function in pre-manifest and manifest HD subjects to establish an HD subject metabolic hormonal plasma signature. Individuals at risk for HD who have had predictive genetic testing showing the cytosine-adenine-guanine (CAG expansion causative of HD, but who do not yet present signs and symptoms sufficient for the diagnosis of manifest HD are said to be pre-manifest. Pre-manifest and manifest HD patients, as well as both familial and non-familial controls, were evaluated for multiple peripheral metabolism signals including circulating levels of hormones, growth factors, lipids and cytokines. Both pre-manifest and manifest HD subjects exhibited significantly reduced levels of circulating growth factors, including growth hormone and prolactin. HD-related changes in the levels of metabolic hormones such as ghrelin, glucagon and amylin were also observed. Total cholesterol, HDL-C and LDL-C were significantly decreased in HD subjects. C-reactive protein was significantly elevated in pre-manifest HD subjects. The observation of metabolic alterations, even in subjects considered to be in the pre-manifest stage of HD, suggests that in addition, and prior, to overt neuronal damage, HD affects metabolic hormone secretion and energy regulation, which may shed light on pathogenesis, and provide opportunities for biomarker development.

    Molecular imaging in neurology and neuroscience is a suspenseful and fast developing tool in order to quantitatively image genomics and proteomics by means of direct and indirect markers. Because of its high-sensitive tracer principle, nuclear medicine imaging has the pioneering task for the methodical progression of molecular imaging. The current development of molecular imaging in neurology changes from the use of indirect markers of gene and protein expression to the direct imaging of the molecular mechanisms. It is the aim of this article to give a short review on the status quo of molecular imaging in neurology with emphasis on clinically relevant aspects. (orig.)

    Anorexia nervosa is an eating disorder among adolescent girls and young women which, though common, often goes undetected and untreated. Anorexia nervosa is a response for young people with psychological conflicts who try to win love by having a body corresponding to the present-day image, symbolising strength, beauty, attraction, power and success. Anorexia nervosa involves inadequate calorie intake leading to marked cachexia with metabolic and endocrinological disturbances. We investigated dermatological changes in 21 young female anorectics aged 19-24 in an attempt to find dermatological markers which mirror the dynamics of the disease and thus obtain helpful signs for early diagnosis with its important bearing on the outcome. Extensive histories were taken and whole-body examinations performed. Seven sex- and age-matched persons served as a control group. The most common dermatological findings were xerosis (71%, controls 29%), cheilitis (76%), bodily hypertrichosis (62%), alopecia (24%), dry scalp hair (48%), acral coldness (38%), acrocyanosis (33%), periungual erythema (48%), gingival changes (37%), nail changes (29%) and calluses on dorsum of hand due to self-induced vomiting (67%). Our study documented for the first time that a body mass index of anorexia nervosa and in HIV infection. Patients with anorexia nervosa develop early stereotype skin changes which are cardinal diagnostic symptoms and pointers to the diagnosis of eating disorders. During training at the Department of Child and Adolescent Psychiatry in Solothurn one of us (C. H.) was once more able to observe most of the above-described cutaneous and mucocutaneous changes in anorexic adolescents. This paper is intended to stimulate further basic research on this topic. We hope our study will facilitate early diagnosis of anorexia nervosa by the family physician and enable him or her to institute immediate treatment for the eating disorder and thereby improve the prognosis.

    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

    Hypothyroidism has been associated with increased pulmonary morbidity and overall mortality. A systematic review was conducted to identify the prevalence and underlying mechanisms of respiratory problems among patients with thyroid insufficiency. PubMed and EMBASE databases were searched for relevant literature from January 1950 through January 2015 with the following study eligibility criteria: English-language publications; adult subclinical or overt hypothyroid patients; intervention, observational, or retrospective studies; and respiratory manifestations. The Preferred Reporting Items for Systematic reviews and Meta-Analyses statement was followed, and Cochrane's risk of bias tool was used. A total of 1699 papers were screened by two independent authors for relevant titles. Of 109 relevant abstracts, 28 papers underwent full-text analyses, of which 22 were included in the review. Possible mechanisms explaining respiratory problems at multiple physiological levels were identified, such as the ventilator control system, diaphragmatic muscle function, pulmonary gas exchange, goiter caused upper airway obstruction, decreased capacity for energy transduction, and reduced glycolytic activity. Obstructive sleep apnea syndrome was found among 30% of newly diagnosed patients with overt hypothyroidism, and demonstrated reversibility following treatment. The evidence for or against a direct effect on pulmonary function was ambiguous. However, each of the above-mentioned areas was only dealt with in a limited number of studies. Therefore, it is not possible to draw any strong conclusions on any of these themes. Moreover, most studies were hampered by considerable risk of bias due for example to small numbers of patients, lack of control groups, randomization and blinding, and differences in body mass index, sex, and age between subjects and controls. Mechanistic data linking hypothyroidism and respiratory function are at best limited. This area of research is therefore

A total of 220 HIV positive patients, treated in the Benghazi Center of Infectious Diseases and Immunology over a period of 14 years (January 2003 to November 2016, were included in a retrospective study. The patients' age ranged from 7 to 46 years. The study was conducted by reviewing the patients' records using the management information system (MIS. Statistical analysis of the data was carried out by the t-test and Chi square test. Among the studied patients, 119 (54.1% were males and 101 (45.9% were females, and most of them (78.6% were 10 – 19 years of age. The predominant mode of transmission was parenteral transmission, in 95% of patients, and positive family history was observed in 12% of patients. Among the total number of visits to dermatologists, 93% of patients had a single disease. Of the total number of skin diseases diagnosed during the visits, parasitic infestations were seen in 92 patients (21.0%, eczematous and related disorders in 78 patients (17.8%, viral infections in 71 patients (16.2%, bacterial infections in 41 patients (9.3%, and fungal infections in 35 patients (7.9%. Dermatophyte infections were the most common fungal infections recorded in 19 patients (4.3%, followed by Candida infection in 11 patients (2.5%. Warts were found in 5.9% of viral infections, followed by herpes zoster (4.1%. HIV positive patients should be examined for skin disorders, because early diagnosis and management of such problems improves the quality of life in these patients.

    Full Text Available Zaheer Mangera, Kirat Panesar, Himender MakkerRespiratory Medicine, North Middlesex University Hospital, London, UKAbstract: Patients with certain neurological diseases are at increased risk of developing chest infections as well as respiratory failure due to muscular weakness. In particular, patients with certain neuromuscular disorders are at higher risk. These conditions are often associated with sleep disordered breathing. It is important to identify patients at risk of respiratory complications early in the course of their disease, although patients with neuromuscular disorders often present in the acute setting with respiratory involvement. This review of the respiratory complications of neurological disorders, with a particular focus on neuromuscular disorders, explores why this happens and looks at how to recognize, investigate, and manage these patients effectively.Keywords: respiratory failure, respiratory muscle weakness

    Full Text Available Leptospirosis is a re-emerging zoonosis occurring as large outbreaks throughout the world caused by Leptospira interrogans. The incidence of pulmonary involvement in leptospirosis has been reported to be increasing in the last years, affecting up to 70% of the patients. Alveolar hemorrhage presented as dyspnea and hemoptysis is the main pulmonary manifestation. The emergence of massive hemoptysis and acute respiratory distress syndrome has characterized the recent changes reported in the clinical patterns of leptospirosis. The pulmonary involvement has been emerged as a serious life threat, becoming the main cause of death due to leptospirosis in some countries. In this review we present the main clinical and pathological manifestations of pulmonary involvement in leptospirosis, with special focus on recent data concerning the pathophysiological mechanisms underlying lung injury.

    We explored the possibility that neurologic and neuropsychological changes constitute the earliest detectable manifestations of human immunodeficiency virus (HIV) infection. Without knowledge of HIV status, we assessed neurologic signs and symptoms and administered a battery of neuropsychological tests to 208 homosexual men, of whom 84 were HIV negative, 49 were HIV positive and asymptomatic, 29 were mildly symptomatic, and 46 had significant medical symptoms but not the acquired immunodeficiency syndrome. There was no difference between the HIV-negative and HIV-positive men in the frequency of neurologic signs or of defective or borderline performance on any neuropsychological test. However, HIV-positive men performed slightly but significantly worse than HIV-negative men on tests of verbal memory, executive function, and language. Similar results were obtained when comparisons were limited to HIV-positive medically asymptomatic and HIV-negative men. There was no degradation of neurologic status or neuropsychological performance across stages of HIV severity, but neurologic and neuropsychological summary scores correlated with CD4/CD8 ratios in the HIV-positive group. Ratings of neurologic signs and symptoms correlated with neuropsychological summary scores in the HIV-positive group only. Cognitive complaints were more frequent in the HIV-positive men; they correlated with actual test performance in the HIV-positive but not HIV-negative men. The constellation of subjective and objective neuropsychological and neurologic findings suggests the possibility of a definable syndrome associated with HIV infection in asymptomatic individuals.

    Chronic migraine is a primary headache that is difficult to treat and has an important impact on the patient's quality of life. The international headache classification recently modified the criteria for chronic migraine and therefore few studies have been conducted that analyse groups according to these new criteria. AIM. To analyse a group of patients with chronic migraine who were referred to a general neurology service. The first 100 patients with migraine were selected. Researchers established and analysed a number of subgroups of patients with episodic, chronic or chronic migraine with probable headache due to medication abuse, in accordance with the International Headache Society (IHS) headache classification and its revised version from 2006. Of the total sample of 738 new patients, 100 (13.5%) suffered from migraines and of these 100 new patients with migraine 42 (5.6% of the total series) satisfied criteria for chronic migraine and 15 patients with chronic migraine met the criteria for probable headache due to medication abuse. Before visiting the neurology service, only 41% had been diagnosed as suffering from migraine, 38% had received no information about this condition, only 17% took triptans for symptomatic relief and 23% had followed some kind of preventive treatment. One notable finding was the importance of episodic and chronic migraine in a general neurology service, on applying the recent IHS criteria. A high percentage of patients with chronic migraine who were referred to the neurology service have not been diagnosed or given any information or proper treatment; an elevated degree of self-medication and medication abuse also exists. Preventive treatment and triptans in cases of intense migraines are still not commonly used in primary care.

    1997-01-01

    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.

    2014-01-01

    Background The epidemiology, pathogenesis, diagnosis, and management of Aspergillus osteomyelitis are not well understood. Methods Protocol-defined cases of Aspergillus osteomyelitis published in the English literature were reviewed for comorbidities, microbiology, mechanisms of infection, clinical manifestations, radiological findings, inflammatory biomarkers, antifungal therapy, and outcome. Results Among 180 evaluable patients, 127 (71%) were males. Possible predisposing medical conditions in 103 (57%) included pharmacological immunosuppression, primary immunodeficiency, and neutropenia. Seventy-three others (41%) had prior open fracture, trauma or surgery. Eighty (44%) followed a hematogenous mechanism, 58 (32%) contiguous infections, and 42 (23%) direct inoculation. Aspergillus osteomyelitis was the first manifestation of aspergillosis in 77%. Pain and tenderness were present in 80%. The most frequently infected sites were vertebrae (46%), cranium (23%), ribs (16%), and long bones (13%). Patients with vertebral Aspergillus osteomyelitis had more previous orthopedic surgery (19% vs 0%; P=0.02), while those with cranial osteomyelitis had more diabetes mellitus (32% vs 8%; P=0.002) and prior head/neck surgery (12% vs 0%; P=0.02). Radiologic findings included osteolysis, soft-tissue extension, and uptake on T2-weighted images. Vertebral body Aspergillus osteomyelitis was complicated by spinal-cord compression in 47% and neurological deficits in 41%. Forty-four patients (24%) received only antifungal therapy, while 121(67%) were managed with surgery and antifungal therapy. Overall mortality was 25%. Median duration of therapy was 90 days (range, 10–772 days). There were fewer relapses in patients managed with surgery plus antifungal therapy in comparison to those managed with antifungal therapy alone (8% vs 30%; P=0.006). Conclusions Aspergillus osteomyelitis is a debilitating infection affecting both immunocompromised and immunocompetent patients. The most

    2017-06-01

    Full Text Available BACKGROUND Takayasu arteritis is a chronic inflammatory vasculopathy mainly affecting the aorta and its main branches and rarely the pulmonary artery. It usually affects females of the childbearing age group and is more prevalent in the South East Asian countries. 1 Ocular manifestations are not uncommon in cases of Takayasu arteritis. They may be ischaemic ocular manifestations when aorta and its branches are involved and get stenosed or hypertensive retinopathy when renal or suprarenal aorta is involved. 2 Uyama and Asayama broadly classified the ocular manifestations into three types. 3 Type 1 comprised of the ischaemic ocular manifestations of Takayasu arteritis, termed as Takayasu Retinopathy which has been further classified into four stages. Stage one is characterised by the distention of veins, stage two consists of microaneurysm formation, occurrence of arteriovenous anastomoses indicates stage three and complications like retinal ischaemia, neovascularisation, rubeosis iridis and vitreous haemorrhage occurs in stage four. Type two ocular findings have features of mixed retinopathy and type three had retinal manifestations due to hypertension which occurs due to the involvement of the renal and abdominal aorta. Since this disease occurs predominantly in younger individuals it causes severe ocular morbidity in the young if not diagnosed and intervened at an early stage. The aim of this study was to evaluate the clinical spectrum of ocular findings in patients with Takayasu arteritis and to describe the Fundus Fluorescein angiographic characteristics of various retinal findings in patients with Takayasu arteritis. MATERIALS AND METHODS 63 patients who were diagnosed as Takayasu Arteritis who attended our tertiary eye care centre in the time period of November 2014 to march 2017 were included in our study. RESULTS This cross-sectional study consisted of 63 patients. The mean age of the presentation of the study population was 27.8 years

    Lor, E; Liu, Y Q

    1994-09-01

    To report three cases of possible foscarnet-induced neurologic sequelae. We report two cases of seizures and one case of hand cramping and finger paresthesia after starting foscarnet therapy with no evidence of predisposing risk factors, such as serum laboratory abnormalities, renal dysfunction, or known central nervous system (CNS) involvement. All three patients had stable laboratory values during therapy and when the neurologic adverse effects occurred. All patients were receiving appropriate dosages of foscarnet. The incidence of seizures in AIDS patients was reviewed. A history of CNS lesions, infections, and/or AIDS per se may increase the risk of a neurologic adverse effect while receiving foscarnet therapy. Acute ionized hypocalcemia may cause these neurologic adverse effects. Ionized hypocalcemia is transitory, is related to the rate of foscarnet infusion, and may not be reflected as a change in total serum calcium concentration. Foscarnet probably contributed to the neurologic adverse effects reported here. Foscarnet may need to be administered at a slower rate than is recommended by the manufacturer. Electrolytes must be monitored closely; however, a neurologic adverse effect may not be foreseen.

    Tropical neurology began less than two centuries ago. Consumption of dietary toxins predominated at the beginning and gave birth to the geographic entity. The story moved from lathyrism through Jamaican neuropathy to cassava-induced epidemic neuropathy, which was contrasted with Konzo, also associated with cassava. Other tropical diseases enumerated with chronological details include: Chaga's diseases, kwashiorkor, Madras type of motor neuron disease, atlanto-axial dislocation, Burkitt's lymphoma and Kuru, associated with cannibalism among the Fore linguistic group in New Guinea. More recent documentation includes the Cuban neuropathy in 1991 with an epidemic of visual loss and neuropathy, Anaphe venata entomophagy in Nigeria presenting as seasonal ataxia, and neurological aspects of the human immunodeficiency virus infection complete the picture. With time, professional associations were formed and the pioneers were given prominence. The World Federation of Neurology featured Geographic Neurology as a theme in 1977 and Tropical Neurology was given prominence at its 1989 meeting in New Delhi, India. The situation remains unchanged with regards to rare diseases like Meniere's, multiple sclerosis, hereditary disorders. However, with westernization and continued urbanization, changing disease patterns are being observed and tropical neurology may depart from dietary toxins to more western world-type disorders.

    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.

    Sacral agenesis is an uncommon congenital disorder that involves multiple organs. We studied neurological manifestations of the disease, common associated disorders, and their relation with extent of bony malformation. We investigated neurological manifestations of 50 patients with sacral agenesis. Patients were evaluated for previous procedures, ambulation, limb abnormalities, vertebral alignment, recurrent urinary tract infection, urinary incontinence, dribbling, dimple, lower extremities weakness, myelomeningocele (MMC), and lipomyelomenangocele. Weakness of lower extremities was seen in 37 (74%) patients. Concurrent weakness of proximal and distal muscles of the lower limb was statistically associated with a type of bony aplasia (P = .001). However, paraplegia was seen in only 2 of 44 children over the age of 1, and the rest could walk. Myelodysplastic syndromes were seen in 21 patients. Sacral agenesis is diagnosed in children with concomitant MMC at younger ages and reveals more severe symptoms. Progression of neurological disorders was seen in 19 patients, in all of whom MRI showed tethering of the spinal cord. Urinary disorders including diurnal urinary incontinence (in 30 of 35 children over age 4) and recurrent urinary tract infections (in 37) were also common. Imperforate anus was seen in 11 patients. Twelve children over age 4 reported fecal incontinence, a problem that had statistically significant association with imperforate anus (P = .013). Different disorders can concurrently affect patients with sacral agenesis that may have profound impressions on patients and their families. Early diagnosis, thorough evaluation, and proper intervention are of utmost importance as they can prevent or lessen future complications.

    Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease of unknown etiology with many clinical manifestations. The skin is one of the target organs most variably affected by the disease. The American College of Rheumatology (ACR) established 11 criteria as a classificatory instrument to operationalise the definition of SLE in clinical trials. They were not intended to be used to diagnose individuals and do not do well in that capacity. Cutaneous lesions account for four of these 11 revised criteria of SLE. Skin lesions in patients with lupus may be specific or nonspecific. This paper covers the SLE-specific cutaneous changes: malar rash, discoid rash, photosensitivity, and oral mucosal lesions as well as SLE nonspecific skin manifestations, their pathophysiology, and management. A deeper thorough understanding of the cutaneous manifestations of SLE is essential for diagnosis, prognosis, and efficient management. Thus, dermatologists should cooperate with other specialties to provide optimal care of SLE patient. PMID:22888407

    Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

    Full Text Available A woman with temporal lobe epilepsy manifesting with repeated episodes of sudden diarrhea and loss of consciousness is reported. A 63-year-old, right-handed female presented with chief complaints of sudden diarrhea and loss of consciousness for almost three decades. The first attack occurred in her 30s, and similar attacks repeated several times in a year. Her attacks comprised abrupt abdominal discomfort, diarrhea, sudden emergence of old memories relating to when she had played with her brother in her childhood, and loss of consciousness during defecation. She had no convulsion or automatism and fully recovered in a few minutes. Every time she was transferred to emergency hospital by ambulance, she had examinations such as blood test, head computed tomography, electrocardiogram, abdominal ultrasound, and electroencephalography (EEG, but no specific diagnosis was made. On admission to our hospital, vital signs, neurological examination, and blood tests did not show abnormal findings. During long-term video-EEG monitoring for 40 h, she had no habitual event. Interictal EEG showed intermittent irregular delta waves and sharp regional transients in the left anterio-midtemporal area. Sharp transients were not as outstanding from background activities as to be defined as epileptiform discharges, but they were reproducible in morphology and distribution and appeared not only in sleep but also in wakefulness. Brain magnetic resonance imaging was unremarkable. Single-photon emission computed tomography showed a decrease of blood flow in the left frontal and temporal lobes. Wechsler Adult Intelligence Scale—III showed a decline of verbal comprehension. We concluded that the patient was suffering from partial epilepsy originating from the left temporal lobe. Carbamazepine markedly improved her seizures. Temporal lobe epilepsy can manifest with diverse autonomic symptoms and signs. Abdominal sensations often herald the onset of epileptic seizures

    Full Text Available This disorder is too rare that about 100 patients have been reported in the world. In this condition a liver enzyme (methylmalonyl CoA mutase which should carry out one of many thousands of chemical processes that turn protein into energy or body tissues is defective. Clinical presentation of this disorder in first months of life may be failure to thrive, lethargy, poor feeding, mental retardation and seizures. Late-onset manifestations include other neurologic findings e.g. dementia, myelopathy and gait disorder. Increases in levels of plasma methylmalonic acid and homocystine confirm the diagnosis. Unlike patients with classic homocystinuria, plasma level of methionine is normal in these patients. The patient was 13.5 years old girl that presented to us due to convulsion, losing the ability to walk, loosing appetite, developing urinary incontinence and showing intellectual regression. In a number of investigations, there was severe increasing in urinary and plasma levels of methylmalonic acid and homocysitine. The patient has commenced on treatment with high doses of vitamin B12, Betaine and Carbamazepine and also physiotherapy. Following the treatment marked improvement in neurologic and mental state appeared and also Methylmalonic acidemia and homocystinuria was controlled.

    Conclusion: SOD is a clinically heterogeneous disorder with a wide spectrum of ophthalmic, endocrine, and neurologic manifestations. All features might not be present in a single patient. A high consanguinity rate and lack of history of alcohol and drug use were observed in our cohort. Most affected children present first to the pediatrician with failure to thrive. Radiological confirmation of ONH necessitates high-resolution imaging and interpretation by an experienced neuro-radiologist. In our cohort, all patients with ONH had associated optic chiasmal hypoplasia. Early detection and treatment reduces disease-related morbidity, and can be life saving.

    Full Text Available Refeeding syndrome is defined as electrolyte and fluid abnormalities that occur in significantly malnourished patients when they are refed orally, enterally, or parenterally. The principal manifestations include hypophosphatemia, hypokalemia, vitamin deficiencies, volume overload and edema. This can affect multiple organ systems, such as the cardiovascular, pulmonary, or neurological systems, secondary to the above-mentioned abnormalities. Rarely, patients may develop gastrointestinal symptoms and show abnormal liver function test results. We report the case of a 52-year-old woman with anorexia nervosa who developed refeeding syndrome and simultaneous elevations of liver function test results, which normalized upon the resolution of the refeeding syndrome.

    2008-12-01

    Full Text Available Introduction: Cystic Fibrosis is the most common recessive autosomic genetic disease among Caucasians. It's caused by mutations in the gene that decodes regulatory protein for transmembrane conductance, resulting in defective transport of chlorine. Objective: Review the literature about Cystic Fibrosis, with emphasis on otorhinolaryngologic manifestations. Method: The online Pub Med databases were researched and we applied the following search terms Fibrosis Cystic and Sinusitis, and Mucoviscidosis and Sinusitis. Conclusions: Although it is not the main cause of death, the otorhinolaryngologic manifestations of the Cystic Fibrosis bring important morbidity to these patients.

    2015-01-01

    Idiopathic pulmonary fibrosis (IPF) is a parenchymal lung disease characterized by progressive interstitial fibrosis. The clinical course of IPF can be unpredictable and may be punctuated by acute exacerbations. Although much progress is being made in unraveling the mechanisms underlying IPF, effective therapy for improving survival remains elusive. Longitudinal disease profiling, especially in terms of clinical manifestations in a large cohort of patients, should lead to proper management of the patients and development of new treatments for IPF. Appropriate multidisciplinary assessment in ongoing registries is required to achieve this. This review summarizes the current status of the diagnosis and clinical manifestations of IPF.

    Skeletal manifestations of chloroma were reviewed in five patients. In four cases, a chloroma was the initial manifestation of a systemic disease. In the fifth, an elderly patient developed a bone lesion during a blastic crisis while under treatment for chronic myelogeneous leukemia. Two patients presented with lytic lesions of the ribs, two with lytic lesions of the femur, and one with a predominantly sclerotic lesion of the scapula. The laboratory findings in two patients were within normal limits. All lesions were confirmed by bone biopsy. (orig.).

    Besides the lungs, tuberculosis (TB) can affect any organ system. In most cases, extrathoracic TB occurs in immunosuppressed patients as part of a severe illness via hematogenous spread. Extrathoracic involvement most commonly involves abdominal organs, especially the urogenital tract and less commonly the central nervous system (CNS) and the musculoskeletal system. Most frequently, computed tomography (CT) is used for detecting extrathoracic TB manifestations, except for CNS and musculoskeletal manifestations, where contrast-enhanced magnetic resonance imaging (MRI) is the gold standard. Extrathoracic manifestations of TB may be indistinguishable from inflammatory or malignant causes. Due to unspecific symptoms the diagnosis is often delayed. This article summarizes and discusses the various radiological manifestations of extrathoracic manifestation of TB. Radiological modalities for screening extrathoracic TB are CT and MRI. Conventional X-radiographs do not play a role in the diagnosis of extrathoracic TB. The possibility of extrathoracic TB should be considered particularly in immunosuppressed patients, such as the homeless, alcoholics or drug addicts or in patients with an immigrant background from the endemic areas of TB. The most likely site of extrathoracic TB is the abdomen; however, infections of the CNS or musculoskeletal systems and multisystem infections can also occur. In patients with suspected extrathoracic TB, radiological modalities for screening are CT, especially for abdominal infections and lymphadenopathy and MRI with contrast media for the musculoskeletal system and the CNS.

    2016-06-01

    Full Text Available Background: Melanoma is a malignancy derived from the neural crest, constituted of melanocytes found in the basal layer of epidermis, with the main function of melanin production. Case: A 64-year-old woman was admitted with headache and dyslalia and reported some episodes of vertigo and falls in the last six months. A superficial red and dark skin discoloration in the scalp and a node in the right parotid gland were observed. Computed tomography of the brain showed nodular lesions in the left parietal and right temporal and occipital lobes with hemorrhagic features, in addition to mass effect. Furthermore, PET-CT images were suggestive of brain, lung, and adrenal metastasis. The patient evolved with intracranial hypertension and a neurosurgery was performed. Histopathological and immunohistochemistry studies revealed metastatic melanoma. Conclusions: She underwent schedules of radiation therapy and chemotherapy, but developed uncontrolled sepsis and died in spite of clinical management and intensive care support. Cutaneous primary site of this malignancy in the scalp was previously neglected; therefore, neurological disturbances were the initial manifestations of melanoma. Immunohistochemistry findings allowed ruling out the main differential hypotheses.

    Full Text Available Abstract Most inborn errors of metabolism (IEM are recessive, genetically transmitted diseases and are classified into 3 main groups according to their mechanisms: cellular intoxication, energy deficiency, and defects of complex molecules. They can be associated with endocrine manifestations, which may be complications from a previously diagnosed IEM of childhood onset. More rarely, endocrinopathies can signal an IEM in adulthood, which should be suspected when an endocrine disorder is associated with multisystemic involvement (neurological, muscular, hepatic features, etc.. IEM can affect all glands, but diabetes mellitus, thyroid dysfunction and hypogonadism are the most frequent disorders. A single IEM can present with multiple endocrine dysfunctions, especially those involving energy deficiency (respiratory chain defects, and metal (hemochromatosis and storage disorders (cystinosis. Non-autoimmune diabetes mellitus, thyroid dysfunction and/or goiter and sometimes hypoparathyroidism should steer the diagnosis towards a respiratory chain defect. Hypogonadotropic hypogonadism is frequent in haemochromatosis (often associated with diabetes, whereas primary hypogonadism is reported in Alström disease and cystinosis (both associated with diabetes, the latter also with thyroid dysfunction and galactosemia. Hypogonadism is also frequent in X-linked adrenoleukodystrophy (with adrenal failure, congenital disorders of glycosylation, and Fabry and glycogen storage diseases (along with thyroid dysfunction in the first 3 and diabetes in the last. This is a new and growing field and is not yet very well recognized in adulthood despite its consequences on growth, bone metabolism and fertility. For this reason, physicians managing adult patients should be aware of these diagnoses.

    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

    The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD. Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment. In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly. The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment. © 2016 Japan Pediatric Society.

    Neurologic swallowing disorders are an increasing diagnostic problem in our overaged population. Undiagnosed chronic aspiration pneumonia is the cause of death in 20-40% of all inhabitants of nursing homes. In neurologic diseases of the pharynx, the physiologic interaction of pharyngeal contraction, closure of the pharynx, and esophageal motility are frequently disturbed. This may be due to cortical, bulbar, or cerebellar brain damage of ischemic or traumatic origin. Furthermore diseases or peripheral nerves, muscles, and synapses cause disturbances. The most life-threatening complication of these disturbances is tracheal aspiration, which requires an iso-osmolar contrast medium for imaging studies that cause no or minimal pulmonary problems. Utilizing fast dynamic documentation we can analyze the swallowing act in 35 images within the passage time of 0.7 s. This requires digital frame sequences from 15-50 images/s, which can be provided by DSI or videofluoroscopy. Neurologic and neuromuscular patterns are demonstrated with and without tracheal aspiration. The differentiation of aspiration in a so-called pre-, intra-, and postdeglutitive form is possible. We distinguish four grades of severity of aspiration, which is also of great clinical impact for the differential rehabilitation therapy. The efficiency of the rehabilitation protocol can be assessed by the dynamic swallowing studies. (orig.) [de

  11. The neurological legacy of John Russell Reynolds (1828-1896).

    2007-04-01

    Sir John Russell Reynolds was an eminent and highly influential physician in the Victorian era who held the Presidencies of the Royal College of Physicians of London, and of the British Medical Association. He was the protégée of the great experimental physiologist, Marshall Hall, who discovered the reflex arc, and succeeded to Hall's clinical practice in London. Reynolds' thought and clinical activities linked the emerging British neurology of the first half of the 19th century with its blossoming, particularly in London, from 1860 onwards. In his writings Reynolds was the first English author to apply the approach to classification of neurological disorders that is still often used, though now in modified form. He was also the first to enunciate the notion of positive and negative symptoms arising from neurological disease and to suggest their pathogenesis, and was arguably the originator of the influential concept that an idiopathic disease, epilepsy, existed, one to be distinguished from 'epileptiform' seizures due to brain pathology.

    Full Text Available The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    OBJECTIVE The aim of this study was to assess the outcome of neurosurgical treatment in children with bleeding diathesis and also to evaluate the current management plan applied in the authors' service. METHODS The authors retrospectively analyzed all cases in which neurosurgical procedures were performed in pediatric patients presenting with intracranial hematoma due to an underlying bleeding tendency over a 5-year period at their institution. They evaluated the patients' neurological symptoms from the initial referral, hematological abnormalities, surgical treatment, neurological outcome, and scores on the Pediatric Glasgow Outcome Scale-Extended (GOS-E Peds) obtained 1 year after the last operation. RESULTS Five patients with a bleeding diathesis who underwent surgery for intracranial hematoma were identified; the diagnosis was hemophilia A in 3 cases, idiopathic thrombocytopenic purpura in 1 case, and severe aplastic anemia in 1 case. Intracerebral hematoma (ICH) (n = 4) and acute subdural hematoma (n = 1) were confirmed on radiological investigations. In 2 of the 4 patients with ICH, the diagnosis of bleeding diathesis was made for the first time on presentation. Four patients (all male) were younger than 2 years; the patient with severe aplastic anemia and spontaneous ICH was 15 years old and female. The duration of symptoms varied from 24 hours to 5 days. Neurological examination at 1 year's follow-up showed complete recovery (GOS-E Peds score of 1) in 3 cases and mild weakness (GOS-E Peds score of 2) in 2 cases. CONCLUSIONS Neurosurgical management of patients with bleeding diathesis should be carried out in a tertiary-care setting with multidisciplinary team management, including members with expertise in neuroimaging and hematology, in addition to neurosurgery. Early diagnosis and prompt treatment of a bleeding diathesis is crucial for full neurological recovery.

    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

    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.

    Full Text Available Objective: To examine the intervertebral disc characteristic on magnetic resonance imaging (MRI in lumbar herniated disc (LHD patients with progressive neurological deficit. Methods: Patients were collected retrospectively from Dr. Hasan Sadikin General Hospital Database from 2011–2013 with LHD, had neurological deficit such as radiculopathy and cauda equine syndrome for less than four weeks with a positive sign confirmed by neurological examination and confirmatory with MRI examination. Results: A total of 14 patients with lumbar herniated disc disease (10 males, 4 females suffered from progressive neurological deficit with an average age of (52.07±10.9 years old. Early disc height was 9.38±0.5 mm and progressive neurological deficit state disc height was 4.03±0.53 mm, which were significantly different statisticaly (p<0.01. Symptoms of radiculopathy were seen in 11 patients and cauda equine syndrome in three patients. Modic changes grade 1 was found in five patients, grade 2 in eight patients,grade 3 in one patient, Pfirmman grade 2 in eleven patients and grade 3 in three patients. Thecal sac compression 1/3 compression was seen in four patients and 2/3 compression in ten patients. Conclusions: Neurosurgeon should raise concerns on the characteristic changes of intervertebral disc in magnetic resonance imaging examination to avoid further neural injury in lumbar herniated disc patients.

    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.

    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.
