Seven right-handed control volunteers and seven preoperative adult epileptic patients performed a rhyme decision (language condition and a visual detection (control condition tasks in visually presented words and unreadable characters, respectively. All patients were left hemisphere dominant for language. Appropriate statistical analyses provided the following preliminary results: (1 patients compared with healthy subjects showed lower degree of hemispheric lateralization with supplementary involvement of the right hemisphere; (2 the degree of hemispheric specialization depends on the considered region; (3 patients with early seizures show signs of temporal and parietal reorganization more frequently than patients with late onset of seizures; (4 patients with early seizures show a tendency for intra-hemispheric frontal reorganisation; (5 associated hippocampal sclerosis facilitates the inter-hemispheric shift of temporal activation. Although our patients were left hemisphere predominant for language, the statistical analyses indicated that the degree of lateralization was significantly lower than in healthy subjects. This result has been considered as the indication of atypical lateralization of language.Keywords: language, fMRI, plasticity, temporal epilepsy, age, hippocampal sclerosis

    On the grounds of literature and own clinical experience, pathological changes in epilepitic patients have been described. Dental management procedures in these patients have also been presented. The unquestionable importance of prophylaxis, which may markedly minimize the impact of epilepsy on the incidence of mouth diseases, has been emphasised. It has also been stated that epileptic patients should receive specialised and integrated dental treatment.

    Epilepsy is a neurological disorder characterized by interruption of normal neuronal functions that is manifested by behavioral disorders, changing of awareness level, and presence of some sensory, autonomic and motor symptoms or signs. It is resulted from many different causes. Many antiepileptic drugs (AEDs) are considered to manage epileptic attacks. Some of them change metabolism and absorption of many nutrients. Therefore, epileptic patients may be in higher risk of nutrient deficiency and its unwelcome effects. In the present paper, we intend to review the relationship between nutrition and epilepsy in two aspects. In one aspect we discuss the nutritional status in epileptic patients, the causes of nutritional deficiencies and the way of compensation of the nutrient deficiencies. It will guide these patients to have a healthy life. In another aspect we explain the role of some nutrients and specific diets in management of epileptic attacks. It can help to better control of epileptic attacks in these patients.

    Full Text Available Epilepsy is one of the most common neurological disorders which a physician might come across in his career life. On the other hand, migraine is common disorders in society chronic headache such as migraine in epileptic patients give ride to difficulties in seizure treatment due to altering the sleeping pattern and calmness disarrangement. Therefore, early diagnosis and suitable treatment in epileptic patients is definitely inevitable, and it will help in a more desirable patients' treatment. So we aimed to evaluate the prevalence of migraine in epileptic patients and relation between these two disorders. Number of 150 epileptic patients attended to neurology clinic of Shohadaye Tajrish Hospital and Iranian Epilepsy Association between June 2010 to May 2011 were fulfilled the questionnaire, and the data has been assessed by SPSS software. In this study, we used MS-Q (migraine screening -questionnaire designed for early diagnosis of migraine in the general population. From all patients filling the questionnaire, the prevalence of migraine (with or without aura was as follows: 23 persons had criteria compatible with migraine with aura; 26 patients had migraine without aura. Migraine was more common in these patients: persons with academic degrees, women, patients who were used 2 antiepileptic drugs, and patients with high BMI. In this study, we showed that migraine in epileptic patients is more prevalent than the general population. Thus, early diagnosis and efficient treatment of migraine headache in these patients is mandatory. More studies are needed for evaluation of this issue.

    Full Text Available Epileptic encephalopathies are motor-mental retardations or cognitive disorders secondary to epileptic seizures or epileptiform activities. Encephalopaties due to brain damage, medications, or systemic diseases are generally not in the scope of this definition, but they may rarely accompany the condition. Appropriate differential diagnosis of epileptic seizures as well as subclinical electroencephalographic discharges are crucial for management of seizures and epileptiform discharges and relative regression of cognitive deterioration in long-term followup. Proper antiepileptic drug, hormonal treatment, or i.v. immunoglobulin choice play major role in prognosis. In this paper, we evaluated the current treatment approaches by reviewing clinical electrophysiological characteristics of epileptic encephalopathies.

    Full Text Available 223 epileptics patients and their families and 136 teachers from public and private schools were submitted to similar questionnaires related to inheritance, transmission, cure, complilcation rates, care during seizures, need for information on the disease, habits, comparison with other diseases and to the educational and social performances of epileptics. Cure and complication nates accounted for the main differences between those populations. Epileptics could recognize a bigger number of complications but still expected to be cured from the disease. The majority of teachers and patients have never been informed about epilepsy and this finding was related to the big number of equivocal answers obtained from them. Put together, the data showed that social and educational performance of epileptic patients could be disturbed by medical and social parameters. Some, of them could be improved by an educational program towards these aspects of epilepsy.

  9. Adult neurogenesis in the intact and epileptic dentate gyrus.

    2007-01-01

    Neurogenesis persists throughout life in the adult mammalian dentate gyrus. Adult-born dentate granule cells integrate into existing hippocampal circuitry and may provide network plasticity necessary for certain forms of hippocampus-dependent learning and memory. Neural stem cells and neurogenesis in the adult dentate gyrus are regulated by a variety of environmental, physiological, and molecular factors. These include aging, stress, exercise, neurovascular components of the stem cell niche, growth factors, neurotransmitters, and hormones. Seizure activity also influences dentate granule cell neurogenesis. Production of adult-born neurons increases in rodent models of temporal lobe epilepsy, and both newborn and pre-existing granule neurons contribute to aberrant axonal reorganization in the epileptic hippocampus. Prolonged seizures also disrupt the migration of dentate granule cell progenitors and lead to hilar-ectopic granule cells. The ectopic granule neurons appear to integrate abnormally and contribute to network hyperexcitability. Similar findings of granule cell layer dispersion and ectopic granule neurons in human TLE suggest that aberrant neurogenesis contributes to epileptogenesis or learning and memory disturbances in this epilepsy syndrome.

    Transient epileptic amnesia is a seizure disorder, usually with onset in the middle-elderly and good response to low dosages of antiepileptic drugs. We describe the clinical, electroencephalography (EEG), and neuroimaging features of 11 patients with a temporal lobe epilepsy characterized by amnesic seizures as the sole or the main symptom. We outline the relevance of a detailed clinical history to recognize amnesic seizures and to avoid the more frequent misdiagnoses. Moreover, the response to monotherapy was usually good, although the epileptic disorder was symptomatic of acquired lesions in the majority of patients.

  11. Phenytoin as the first option in female epileptic patients?

    1999-01-01

    Full Text Available OBJECTIVE: Phenytoin (PHT is one of the first-choice drugs in several epileptic syndromes, mostly in partial epilepsies, in which case it is effective as carbamazepine and phenobarbital. However, like any other anti-epileptic drug (AED, unpleasant side-effects are not rare. The aim of this study is the evaluation of dermatological troubles related to chronic PHT usage in female patients. METHOD: Between 1990-93, 731 new patients underwent investigation for epilepsy at the Multidisciplinary Clinic for Epilepsy in our State. In this sample 283 were AED users at the time of the first assessment. Sixty one female patients taking PHT were identified. They were taking PHT in a dosage ranging from 100 to 300 mg daily, in mono or polytherapy regimen, during 1-5 previous years. RESULTS: More than 50% of the sample showed coarse facial features made by the combination of several degrees of acne, hirsutism and gingival hyperplasia. CONCLUSION: Except in emergency situations, PHT should not be prescribed as the first option to the treatment of female epileptic patients, because not uncommonly the cosmetic side-effects are more socially handicapping than the epileptic syndrome by itself.

    Full Text Available Developmental malformations are brain abnormalities that occur during embryogenesis. Neuronal migration disorders, including heterotopic lesions, constitute one type of such abnormalities. The aim of the study was to compare the epileptic clinical patterns of patients with periventricular nodular heterotopia (PNH (G1 with those affected by subcortical heterotopia (SCH (G2 looking for differences between both groups which, eventually, might suggest the type of the underlying malformation. The variables studied in both groups were: type of the heterotopia depicted on MRI studies, sex, age, age at seizure onset, annual seizure frequency, localization of the ictal symptomatogenic zone, characteristics of the EEG, other associated anomalies on the magnetic resonance images (MRI besides the heterotopia, and response to treatment. The only difference found between both groups was the type of heterotopia as shown by MRI studies. The other assessed variables did not significantly (p>0.05 differ between groups. No differences in the clinical features characterizing epilepsy could be found in patients with PNH or SCH, being the images the only tool able to differentiate them.Las malformaciones de la corteza cerebral son un grupo de entidades que se producen durante las etapas del desarrollo embrionario y cuya manifestación clínica puede ser la epilepsia. Estas malformaciones pueden ser diagnosticadas in vivo a través de las imágenes por resonancia magnética (IRM. Un subtipo particular de éstas lo constituyen los trastornos en la migración neuronal, dentro de los cuales se ubican las heterotopías (HT. El objetivo del estudio fue comparar enfermos portadores de HT periventriculares (G1 con aquellos portadores de HT subcorticales (G2.

    Endocrine changes are reported in both epilepsy and depression. The interrelationships between mood, epilepsy, and endocrine changes are not well characterized. The authors included 40 epileptic patients (20 depressed, 20 nondepressed) and 20 healthy subjects. All patients had an electroencephalogram, and were given the Hamilton Rating Scale for Depression. All subjects were tested for serum levels of cortisol, prolactin, testosterone, and thyroid hormones. Patients were medication-free. Patients had elevated prolactin and cortisol and reduced serum testosterone relative to control subjects. Depressed patients had higher cortisol levels than nondepressed. Data suggest that the effects of epilepsy and depression on cortisol, but not other hormones, may be additive.

    Full Text Available With the aim to study the magnitude of infection by the metacestode of Taenia solium in a population of epileptic patients in the arid region of Bahia, Northeastern Brazil, we examined 200 consecutive cases who attended an ambulatory clinic in the disctrict of Mulungu do Morro. Sixty-six of the patients had a diagnosis of epilepsy. From them 10 (15.2% presented antibodies against a specific fraction of antigens in Western blot, and 4 (6.0% had circulating parasite products, as tested by capture ELISA. Only 1 case was positive for antibodies and antigens. We found that the frequency of seropositivity was related to the time without epileptic seizure. We conclude that cysticercosis is endemic in the region of Mulungu do Morro and that it is related to a benign form of epilepsy.

    Full Text Available OBJECTIVE: The aim of this study was to investigate the frequency of seizures and the clinical features of patients with seizures related to a posterior circulation infarct (POCI. METHODS: We reviewed all ischemic stroke patients admitted to our clinic between January 2011 and January 2012. The patients’ database information was retrospectively analyzed. Fifty-five patients with a POCI were included in the study. We reviewed all patients with epileptic seizures related to a POCI. Age, gender, recurrent stroke, risk factors, etiology, radiographic localization, the seizure type and onset time, and the electroencephalographic findings of patients were evaluated. We excluded all patients who had precipitating conditions during seizures such as taking drugs, acid-base disturbances, electrolyte imbalance, and history of epilepsy. RESULTS: Seizures were observed in four patients (3 male, 1 female with a POCI related epileptic seizures (7.2%. The etiology of strokes was cardiac-embolic in 3 patients and vertebral artery dissection in 1 patient. Seizures occurred in 2 patients as presenting finding, in 1 patient within 7 days, and 1 patient within 28 days. Primary generalized tonic-clonic seizures occurred in 3 patients and simple partial seizures with secondary generalization in 1 patient. Three patients had cerebellum infarction at the left hemisphere. One patient had lateral medullary infarction at the right side. The electroencephalographic findings of patients were normal. CONCLUSION: Studies involving patients with seizures related to a POCI are novel and few in number. Three patients with seizure had cerebellum infarction. The cerebellum in these patients may contribute via different mechanisms over seizure activity.

    The authors describe 2 patients with early infantile epileptic encephalopathy caused by 2 novel mutations involving the STXBP1 gene. The authors suggest that in spite of the rarity of STXBP1 mutations, molecular analysis of STXBP1 gene should be performed in patients with early infantile epileptic encephalopathy, after exclusion of ARX mutations in male patients and CDKL5 mutations in female patients. The potential mechanisms explaining the variable clinical phenotypes caused by STXBP1 mutations are discussed and the designation of early-onset epileptic encephalopathies, including an updated genetic classification, is proposed to encompass the epileptic encephalopathies beginning in the first 6 months of life.

    Atlanto Axial Rotatory Dislocations (AARDs) are a heterogeneous group of post-traumatic pathologies typical of the pediatric age, and rare in adults. We describe the case of a 34-year-old woman, developing Atlanto Axial Rotatory Fixation (AARF) after a generalized tonic-clonic epileptic seizure, an extremely rare traumatic cause never described in literature. AARF was detected only 1 month after the accident and nonsurgical treatment was attempted at the beginning. The patient underwent surgery only 2 months after the accident. The best treatment should be conservative reduction within 1 month; when it is not possible, it is advisable to perform surgery as soon as possible. C1-C2 fixation with Harm's technique is the gold standard for fixed luxations. Delay of treatment makes intraoperative reduction more difficult and increase the establishment of the chronic permanent change of neck muscles and ligaments.

    Full Text Available Pre-surgical evaluation of epileptic patients consists of neurological examination, intensive electroencephalographic (EEG monitoring and anatomical studies (CT and MRI. Functional methods such as PET and SPECT imaging are now used more frequently. We have studied pre-operatively 15 adult epileptic patients (8 female, 7 male using a rotational scintillation camera interfaced to a dedicated computer. The tomographic images were obtained 15 minutes after intravenous injection of 99mTc_HMPAO. All had MRI scanning and intensive EEG monitoring which generally included seizure recording. Five patients had progressive lesions (3 meningiomas, 2 astrocytomas. In 10 patients, neuroradiological studies did not show the presence of progressive lesions (2 normal scans and 8 cases with inactive lesions. Two patients with meningioma showed hypoperfusion at the lesion site while the third patient had a marked hyperperfusion which might correlate with the clinical diagnosis of epilepsia partialis continua. In the astrocytoma patients SPECT scans showed hypoperfusion at the lesion site. Data obtained from the 10 patients without progressive CNS lesions showed: (a in 4, SPECT findings correlated well with the anatomical findings; (b in 5 instances, SPECT was able to disclose additional functional deficits; (c in one case, there was no SPECT correlate of a discrete anatomical lesion. In 5 of these cases with no progressive lesions (n=10 SPECT findings were useful as a complementary tool in determining the clinical or surgical management of these patients. Despite the small number and hete-rogenicity of the present sample, SPECT seems to be an useful tool as part of the clinical workup of epileptic patients who are candidates for epilepsy surgery.

    Full Text Available Epilepsy is a neurological disorder that leads to occasional epileptic seizures, affecting the quality of life. Aim: The aim of the present study was to explore the current psychological and social profile of epileptic patients in Greece and to identify the main differences as compared to a former similar research. Material and Methods: A sample of 91 questionnaires, from a total of 350 inpatients with epilepsy at a Public Hospital, during the years 2008 to 2009 (response rate 26%. For data analysis, we used simple descriptive statistical analysis (at significance level of α=5% and α=10% and factor analysis, using SPSS 16.0. Results: Our research showed that the quality of life of people with epilepsy in Greece seems to have improved significantly during the last decade, as their crises have been reduced by 15,7% and their employment has increased by 13% . Conclusions: All that mean that these people are no longer been placed in the margin of society and they succeed in living a normal life with the certain limitations of their disease.

    Full Text Available The problem of stigmatization of a patient with epilepsy is frequently essential in restricting the capacities of his social performance. Society is often unready to recognize an epileptic patient as its equal member. The authors consider the main sources of social support (SS to patients with epilepsy: the patient’s family takes first place; friends and other important persons also play a major role. The perception of SS has been found to be related to the number of used antiepileptic drugs and the hemispheric lateralization of a leading epileptic focus.

    Full Text Available Aims: To evaluate clinical profile and short-term outcome of psychogenic non-epileptic seizures (PNES in Indian adult population. Setting and Design: A prospective observational study, conducted at tertiary teaching institute at New Delhi. Materials and Methods: Sixty-three patients with confirmed PNES were enrolled. The diagnosis was based on witnessing the event during video-electroencephalography (Video-EEG monitoring. A detailed clinical evaluation was done including evaluation for coexistent anxiety or depressive disorders. Patients were divided into two groups on the basis of excessive or paucity of movements during PNES attacks. Patients were followed-up to 12 months for their PNES frequency. Statistical Analysis: Means and standard deviations were calculated for continuous variables. Chi-square and Students t-test were used to compare categorical and continuous variables respectively. Results: The mean age at onset of PNES was 25.44 years; with F:M ratio of 9.5:1. Coexistent epilepsy was present in 13 (20.63% cases. Twenty-two patients (44% with only PNES ( n = 50 had received antiepileptic drugs. Out of 63 patients of PNES 24 (38.1% had predominant motor phenomenon, whereas 39 (61.9% had limp attacks. The common features observed were pre-ictal headache, ictal eye closure, jaw clenching, resistant behavior, ictal weeping, ictal vocalization, and unresponsiveness during episodes. Comorbid anxiety and depressive disorders was seen in 62.3% and 90.16% patients, respectively. Short-term (6-12 months outcome of 45 patients was good (seizure freedom in 46.66% and >50% improvement in 24.44% cases. Conclusion: PNES is common, but frequently misdiagnosed and treated as epileptic seizures. A high index of suspicion is required for an early diagnosis. Proper disclosure of diagnosis and management of the psychiatric comorbidities can improve their outcome. Limitation: Limited sample size and change in seizures frequency as the only parameter for

    Plasma levels of 25-hydroxycholecalciferol (25-HCC) were measured by a specific competitive protein-binding assay. Mean levels in both normal London adults and adolescent schoolchildren were 16 ng/ml and the mean level in a group of epileptic patients on high-dosage anticonvulsant therapy was 5 ng/ml, (difference from normals P < 0.001). Two further epileptic patients, with well-marked anticonvulsant osteomalacia, were treated with small doses of 25-HCC during full metabolic balance studies; rapid healing followed administration of 25-HCC by mouth in doses of 10-45 mug daily, which is well below the effective dose range of calciferol in this condition. These findings provided further evidence that anticonvulsant osteomalacia results from hepatic enzyme induction which, by increasing the metabolism of cholecalciferol to inactive compounds, lowers 25-HCC levels in patients whose dietary vitamin D intake and exposure to sunlight are otherwise adequate. Results also indicated that under certain circumstances 25-HCC may have considerably stronger antirachitic potency in man than has hitherto been recognized.

    Epilepsy, characterized by the risk of recurrent seizures, is a chronic disease that afflicts about 5% of the world's population. The main dental problems associated with epileptic patients include gingival hyperplasia, minor oral injuries, tooth trauma, and prosthodontic problems, which require the dental treatment. Stress and fear are the most common triggering factors for the epilepsy in dental chair. Therefore, a more appropriate method of treating such epileptic patients may be warranted...

    Epilepsy is a disease of neuronal hyper-synchrony that can involve both neocortical and hippocampal brain regions. While much is known about the network properties of the hippocampus little is known of how epileptic neocortical hyper-synchrony develops. We aimed at characterizing the properties of epileptic discharges of a neocortical epileptic focus. We established a multi-electrode-array method to record the spatial patterns of epileptiform potentials in acute adult rat brain slices evoked by 4-Aminopyridine in the absence of magnesium. Locations of discharges mapped to two anatomical regions over the somatosensory cortex and over the lateral convexity separated by a gap at a location matching the dysgranular zone. Focal epileptiform discharges were recorded in superficial and deep neocortical layers but over superficial layers, they exhibited larger surface areas. They were often independent even when closely spaced to one another but they became progressively coupled resulting in larger zones of coherent discharge. The gradual coupling of multiple, independent, closely spaced, spatially restricted, focal discharges between deep and superficial neocortical layers represents a possible mechanism of the development of an epileptogenic zone.

We established a multi-electrode-array method to record the spatial patterns of epileptiform potentials in acute adult rat brain slices evoked by 4-Aminopyridine in the absence of magnesium. Locations of discharges mapped to two anatomical regions over the somatosensory cortex and over the lateral convexity separated by a gap at a location matching the dysgranular zone. Focal epileptiform discharges were recorded in superficial and deep neocortical layers but over superficial layers, they exhibited larger surface areas. They were often independent even when closely spaced to one another but they became progressively coupled resulting in larger zones of coherent discharge. The gradual coupling of multiple, independent, closely spaced, spatially restricted, focal discharges between deep and superficial neocortical layers represents a possible mechanism of the development of an epileptogenic zone.

    Lennox-Gastaut syndrome (LGS) is characterized by interictal epileptiform discharges (IEDs) occurring during sleep. The aim of this study was to determine whether sleep influences not only the frequency of seizures and IEDs, but also the time-dependent evolution that may support the hypothesis of homeostatic influences on epileptic threshold. Video polysomnography data from our database were reviewed to identify adult LGS patients with at least seven hours of nocturnal recording. Thirteen patients were identified and a second polysomnography was available for nine. The number, duration and index of IEDs, relative to total sleep, sleep stages, and time during the night, were calculated. The majority of IEDs occurred during non-rapid eye movement sleep, mainly in stage 2 and slow-wave sleep. Adjusting for time spent in each sleep stage, we found 45 IEDs/hour in stage 1, 123/hour in stage 2, 106/hour in slow-wave sleep, and 26/hour in rapid eye movement sleep. The temporal distribution of IEDs showed a significant rise in the first three hours of sleep, followed by a progressive decrease at the end of the night (F=85.6; pLGS is facilitated by non-rapid eye movement sleep with an evident effect of stage 2 and slow-wave sleep. The significant IED occurrence in the first part of the night and the subsequent decline suggests a link between epileptic threshold and homeostatic sleep mechanisms. The latter should be considered regarding choice of therapy.

    Repellent guidance molecules provide targeting information to outgrowing axons along predetermined pathways during development. These molecules may also play a role in synaptic reorganization in the adult brain and thereby promote epileptogenesis. Our aim was to investigate the expression of Slit2, one of repellent guidance molecules, in temporal lobe epileptic foci from epileptic patients and experimental animals. Thirty-five temporal neocortex tissue samples from patients with intractable temporal lobe epilepsy (TLE) and fifteen histological normal temporal lobes from controls were selected. Fifty-four Sprague-Dawley rats were divided randomly into six groups, including five groups with epilepsy induced by lithium-pilocarpine administration and one control group. Temporal lobe tissue samples were taken from rats at 1, 7, 14, 30, and 60 days post-seizure and from controls. Expression of Slit2 was assessed by immunohistochemistry, immunofluorescence, and Western blot analysis. Slit2 was mainly expressed in neurons in human controls and in both neurons and astrocytes in TLE patients. Slit2 expression was significantly higher in TLE patients as compared with the controls. Slit2-positive cells were mainly neurons in the rat temporal lobe tissues of the control group, the acute period group, and the latent period group, while the Slit2-positive cells were mainly astrocytes in chronic phase. Compared with controls, Slit2 expression in animals in the TLE group gradually decreased from days 1 to 14 post-seizure, but then increased over the levels seen in controls, to peak levels at days 30 and 60. These results suggest that Slit2 may play an important role in the pathogenesis of TLE.

    GABAergic inhibition and particularly perisomatic inhibition play a crucial role in controlling the firing properties of large principal cell populations. Furthermore, GABAergic network is a key element in the therapy attempting to reduce epileptic activity. Here, we present a review showing the synaptic changes of perisomatic inhibitory neuronal subtypes in the hippocampus of temporal lobe epileptic patients, including parvalbumin- (PV-) containing and cannabinoid Type 1 (CB1) receptor-expressing (and mainly cholecystokinin-positive) perisomatic inhibitory cells, known to control hippocampal synchronies. We have examined the synaptic input of principal cells in the dentate gyrus and Cornu Ammonis region in human control and epileptic hippocampi. Perisomatic inhibitory terminals establishing symmetric synapses were found to be sprouted in the dentate gyrus. Preservation of perisomatic input was found in the Cornu Ammonis 1 and Cornu Ammonis 2 regions, as long as pyramidal cells are present. Higher density of CB1-immunostained terminals was found in the epileptic hippocampus of sclerotic patients, especially in the dentate gyrus. We concluded that both types of (PV- and GABAergic CB1-containing) perisomatic inhibitory cells are mainly preserved or showed sprouting in epileptic samples. The enhanced perisomatic inhibitory signaling may increase principal cell synchronization and contribute to generation of epileptic seizures and interictal spikes. PMID:28116310

    Full Text Available Epilepsy, characterized by the risk of recurrent seizures, is a chronic disease that afflicts about 5% of the world's population. The main dental problems associated with epileptic patients include gingival hyperplasia, minor oral injuries, tooth trauma, and prosthodontic problems, which require the dental treatment. Stress and fear are the most common triggering factors for the epilepsy in dental chair. Therefore, a more appropriate method of treating such epileptic patients may be warranted. Conscious sedation is a technique of providing good anesthesia and analgesia to patients, the main advantage of which is the patient's rapid return to presentation levels. Midazolam used as a sedative agent has anticonvulsant properties.

    Sera from 88 patients from Santa Catarina and São Paulo states of Brazil, with epileptic seizures who underwent cerebral computed tomography (CT) were analyzed for the detection of antibodies to T. solium cysticercus by ELISA and Immunoblot (IB) with the following antigens: Taenia solium cysticercus total saline (Tso), Taenia crassiceps cysticercus vesicular fluid (Tcra-vf) and T. crassiceps cysticercus glycoproteins (Tcra-gp). ELISA carried out with Tso, Tcra-vf and Tcra-gp antigens showed 95%, 90% and 80% sensitivities, respectively, and 68%, 85% and 93% specificities, respectively. In the epileptic patients group, ELISA positivity was 30%, 51% and 35% with Tso, Tcra-vf and Tcra-gp antigens respectively. Considering the IB as the confirmatory test, the positivity was 16% (14/88) in the epileptic patients total group and 22% (12/54) in the epileptic patients with positive CT and signals of cysticercosis. We found a significant statistical correlation among ELISA or IB results and the phase of the disease when any antigens were used (p neurocysticercosis (NC) in patients presenting with epileptic seizures because of the high risk of acquiring NC in our region and its potential cause of epilepsy.

    Objective: To investigate the effects of epileptic discharges in sleep of epileptic patients on sleep-breath events. Methods: Polysomnograph (PSG) and long-term video electroencephalogram (LTVEEG) were used to monitor 82 adult epileptic patients. The condition of paroxysmal events in nocturnal sleep was analyzed, and the epileptiform discharge and effects of antiepileptic drugs were explored. Results: In epileptic group, latency to persistent sleep (LPS) and REM sleep latency increased, the proportion of light sleep increased while that of deep sleep decreased, sleep efficiency reduced, nocturnal arousal times increased and apnea hyponea indexes (AHI) improved, which demonstrated significant differences by comparison to control group. Periodic leg movements (PLM) had no conspicuous differences compared with control group. There were no speciifc effects of epileptiform discharge and antiepileptic drugs on AHI and PLM indexes. Conclusion: Epileptic patients have sleep structure disorders and sleep-disordered breathing, and arousal, respiratory and leg movement events inlfuence mutually. Synchronous detection of PSG combined with LTVEEG is in favor of comprehensively analyzing the relationship between sleep structures and epilepsy-breath events.

    Full Text Available Objective. This study aims to evaluate the incidence of pathological cerebral activity responses to intermittent rhythmic photic stimulation (IPS after a single epileptic seizure. Patients and Methods. One hundred and thirty-seven EEGs were performed at the Neurophysiology Department of Mohamed V Teaching Military Hospital in Rabat. Clinical and EEG data was collected. Results. 9.5% of our patients had photoparoxysmal discharges (PPD. Incidence was higher in males than in females, but p value was not significant (p=0.34, and it was higher in children compared to adults with significant p value (p=0.08. The most epileptogenic frequencies were within the range 15–20 Hz. 63 patients had an EEG after 72 hours; among them 11 were photosensitive (p=0.001. The frequency of the PPR was significantly higher in patients with generalized abnormalities than in focal abnormalities (p=0.001. EEG confirmed a genetic generalized epilepsy in 8 cases among 13 photosensitive patients. Conclusion. PPR is age related. The frequencies within the range 15–20 Hz should inevitably be included in EEG protocols. The presence of PPR after a first seizure is probably more in favor of generalized seizure rather than the other type of seizure. PPR seems independent from the delay Seizure-EEG. Our study did not show an association between sex and photosensitivity.

    We performed the blink reflex (BR) in 20 normal volunteers, 13 epileptic patients receiving antiepileptic drug (AED) monotherapy, and 13 epileptic patients receiving AED polytherapy. Comparison of R1, ipsilateral and contralateral R2 and VIIth nerve latencies in the three groups showed no statistically significant differences R1 and VIIth nerve latencies among the three groups. There were statistically significant differences between the polytherapy group and the monotherapy and control groups in comparisons of ipsilateral and contralateral R2. There were no significant differences between the monotherapy group and the control group for ipsilateral and contralateral R2. We hypothesized that AED polytherapy might interfere with synaptic transmission in the polysynaptic pathway of the blink reflex, prolonging the latency of R2. These results provide further evidence of the pathophysiologic effects associated with polytherapy in epileptic patients.

    Many risk factors are encountered during the pathogenesis of epilepsy. In this study, the effect of seizure frequency on free radical generation and antioxidants levels in epileptic patients was evaluated. This study was carried out on 15 healthy controls (GI) and 60 epileptic patients treated with mono- or poly-therapy of carbamazepine, valproic acid, or phenytoin. The treated epileptic patients were divided into 2 main groups according to the seizure frequency: controlled seizure patients GII (n = 30) and uncontrolled seizure patients GIII (n = 30). GII included the GIIA subgroup (n = 15) which had been seizure free for more than 12 months and the GIIB subgroup (n = 15) which had been seizure free for a period from 6 to12 months. GIII included GIIIA (n = 15) and GIIIB (n = 15) for patients which had a seizure frequency of less than and more than four times/month, respectively. In comparison to the control group (GI), the levels of nitric oxide (NO) and malondialdehyde/creatinine ratio were significantly increased in GIIB, GIIIA, and GIIIB, while vitamins A and E levels were significantly decreased in GIIIB. Serum NO levels had significant negative correlations with serum vitamin E in the GIIA and GIIB groups, and with vitamin A in the GIIIA and GIIIB groups. However, serum NO had positive correlation with urinary MDA/Cr ratio. The imbalance between free radical generation and antioxidant system in epileptic patients may be a factor in seizure frequency.

    Depression is a significant problem in epilepsy. Suicides occur in epileptic patients five times more often than in general population. Material included 34 epileptics with 76 suicidal attempts and 24 patients with no history of suicide. Psychical state was studied with Beck Depression Inventory and Hamilton Depression Rating Scale. In the group with suicidal attempts 65% of patients had depression (54.5% of them had major depression) and in group without suicide attempts depression was noted in 54% (23% with major depression). Patients with depression were divided into two groups: group I with suicidal attempts and group II without history of suicide. In group I more patients were alcohol abusers (50% vs 31%), more were treated because of epilepsy longer than 10 years (59% vs 46%) and more had tonic-clonic seizures (82% vs 46%). In group I, 54% of patients were on polytherapy (more than half of them with fenobarbital). In group II, 31% of epileptics were on polytherapy (no one with fenobarbital). Major depression was significantly more frequent in epileptics with suicidal attempts. The severity of depression may influence the risk of suicide. Major depression may be associated with late age of onset of epilepsy, longer treatment duration, tonic-clonic seizures, polytherapy (mainly with fenobarbital) and alcohol abuse.

    Epilepsy is a common neurodegenerative disease with an increasing morbidity. Clinical treatment of epilepsy includes symptomatic treatment, etiological treatment, surgery and prevention. The aim of the present study was to determine the effects of antiepileptic drugs (AEDs) on serum folate and vitamin B12 in various epileptic patients, and to examine the correlation between these effects and secondary cerebrovascular events. A total of 68 epileptic patients, diagnosed between May 2012 and May 2014, were included in the present study. The study included 8 cases of autonomic seizures, 10 cases of absence seizures, 13 cases of complex partial seizures, 28 cases of generalized tonic-clonic seizures, and 9 cases of simple partial seizures. The patients received appropriate AED treatment according to the characteristics of epileptic seizure and the treatment guidance. The differences in the serum levels of folate and vitamin B12 in these patients, and the differences in the secondary cerebrovascular events in these patients after 1 year follow-up were analyzed. The difference in the AEDs used by various epileptic patients was statistically significant (PB12 in these patients following treatment were significantly lower than those prior to treatment (PB12 in these groups following treatment were not statistically significant (P>0.05). The difference in the incidence of cerebrovascular events in these groups at follow up was not statistically significant (P>0.05). The multifactorial logistic regression analysis revealed that the serum levels of folate and vitamin B12 were the independent risk factors for epilepsy with secondary cerebrovascular events [folate: odds ratio (OR)=0.536, P=0.039; vitamin: OR=0.382, P=0.041]. In conclusion, various AEDs may decrease the serum levels of folate and vitamin B12 and affect the secondary cerebrovascular events in various epileptic patients. Thus, regular supplementation of folate and vitamin B12 may be an option.

    Topiramate is an approved and effective drug in migraine prophylaxis. Paresthesia is the most commonly reported side effect. The primary objective of this study was to compare the frequency of topiramate-induced paresthesia in migraine headache to epileptic patients. Patients with migraine without aura and epilepsy were enrolled in this observational study. All cases were interviewed by telephone about their history of paresthesia. Confounding factors were controlled through logistic regression. The odds ratio of developing topiramate-induced paresthesia in migraine compared to epilepsy patients was 3.4. Three factors were independent contributors to developing topiramate-induced paresthesia: female sex (odds ratio 2.1), topiramate dosage (odds ratio 0.3) and duration of therapy. Our findings indicate an independent association between migraine and development of paresthesia. Migraineurs were more likely than epileptic patients to report paresthesia as topiramate adverse effects. Female sex, treatment duration and topiramate dosage contribute significantly to subsequent development of paresthesia.

    Full Text Available Quantitative measurements have indicated that heredity, cerebral damage, psycho-social aspects, ictal and inter-ictal phenomena and antiepileptic drugs may interfere in the cognitive dysfunction of epileptic patients. In the present study objective methods included immediate and late recall and recognition of pictures, Stroop test and auditory selection. Twenty patients with symptomatic localized epilepsy aged 17-52 years (27±10, mean ±sd were compared to age and socially matched healthy controls. Patients were on therapeutic serum concentrations (25±12 m/mi of phenobarbitone and had active epilepsy with 1.94 generalized tonic-clonic, 0.85 simple partial and 6.28 complex partial seizures monthly (means. Patients performed worse than controls in all 6 tests (p<0.05 to p<0.001, indicating a generalized cognitive deficit related to seizures and/or barbiturate therapy. We suggest further studies should be carried out in populations with uniform monotherapeutic regimens and epileptic syndromes in order to isolate factors related to the cognitive dysfunction of epileptic patients.

    Full Text Available Previous studies reported that the proline-rich transmembrane protein 2 (PRRT2 gene was identified to be related to paroxysmal kinesigenic dyskinesia (PKD, infantile convulsions with PKD, PKD with migraine and benign familial infantile epilepsy (BFIE. The present study explores whether the PRRT2 mutation is a potential cause of febrile seizures, including febrile seizures plus (FS+, generalized epilepsy with febrile seizures plus (GEFS+ and Dravet syndrome (DS; thus, it may provide a new drug target for personalized medicine for febrile seizure patients. We screened PRRT2 exons in a cohort of 136 epileptic patients with febrile seizures, including FS+, GEFS+ and DS. PRRT2 genetic mutations were identified in 25 out of 136 (18.4% febrile seizures in epileptic patients. Five loss-of-function and coding missense mutations were identified: c.649delC (p.R217Efs*12, c.649_650insC (p.R217Pfs*8, c.412C>G (p.Pro138Ala, c.439G>C (p.Asp147His and c.623C>A (p.Ser208Tyr. PRRT2 variants were probably involved in the etiology of febrile seizures in epileptic patients.

    2016-03-01

    The case of a 77-year-old man admitted for suspected epileptic seizure is reported. Patient history showed implantation of a single-chamber implantable cardioverter-defibrillator (ICD) after cardiac arrest in 2007 with replacement in 2012 due to battery depletion; the patient reported no previous syncope, unconsciousness or seizures. Interrogation records of the ICD showed five ventricular tachyarrhythmia episodes that corresponded to the "seizure". Further examination revealed incorrect position of the RV-lead. Diagnosis was a provoked epileptic seizure due to undersensing of ventricular tachycardia because of improper ICD lead implantation in the coronary sinus. Treatment consisted of implantation of a new device with an additional ICD lead into the right ventricle.

    The present study investigated the sensitivity of magnetoencephalography (MEG) for spikes depending on sensor type in patients with mesial temporal epileptic focus. We recorded MEG in 6 patients with mesial temporal epileptic focus using two sensor types (magnetometer and gradiometer) simultaneously. The number of spikes detected and the corresponding equivalent current dipole (ECD) parameters (distance from the coordinated head center (radius), and dipole moment) were evaluated with respect to sensor type. Among 426 MEG 'consensus spikes' determined by 3 reviewers, 378 spikes satisfied the predetermined criteria for source localization. Comparing ECD parameters, spikes detected by magnetometer alone displayed a smaller radius and larger dipole moment than those detected by gradiometer alone. Spikes estimated in the mesial temporal area were more frequently detected by magnetometer alone (38.5%) than by gradiometer alone (11.5%), whereas spikes in the lateral temporal area were detected less by magnetometer alone (3.7%) than by gradiometer alone (53.9%). The present results suggest that a magnetometer is advantageous for spike detection in patients with mesial temporal epileptic focus. This also implies the higher sensitivity of magnetometer for deep sources.

    Full Text Available Based on video recordings of the movement of the patients with epilepsy, this paper proposed a human action recognition scheme to detect distinct motion patterns and to distinguish the normal status from the abnormal status of epileptic patients. The scheme first extracts local features and holistic features, which are complementary to each other. Afterwards, a support vector machine is applied to classification. Based on the experimental results, this scheme obtains a satisfactory classification result and provides a fundamental analysis towards the human-robot interaction with socially assistive robots in caring the patients with epilepsy (or other patients with brain disorders in order to protect them from injury.

    Full Text Available Background Serum prolactin level has been used as a marker to differentiate epileptic from non-epileptic seizures in adults. Electroencephalogram (EEG examination is the primary diagnostic tool used to assess seizures. However, EEGs are quite difficult to perform in children and have sensitivity of only 50%-55%, with 96% specificity. Objective To assess the diagnostic potential of serum prolactin level as an alternative tool for children for differentiating between epileptic and non-epileptic seizures. Methods This diagnostic study was performed between January 2013 and December 2013. Thirty patients aged 3 months to 15 years with seizures and without fever who visited the Emergency Department of Arifin Ahmad Hospital, Pekanbaru, Riau, were included. Blood specimens were collected within 2 hours after seizure. Subjects underwent serum prolactin measurements and EEG examinations. Results Fifteen subjects had normal EEGs and 15 subjects had abnormal EEGs. Post-ictal serum prolactin levels were significantly higher in the epileptiform EEG group. The mean serum prolactin levels were 23.78 (SD 21.86 ng/mL and 10.57 (SD 5.62ng/mL in patients with epileptic and non-epileptic patients, respectively. Using a prolactin cut-off point of 17.2 ng/mL, serum prolactin had a 73.3% sensitivity and 93.3% specificity for differentiating between epileptic and non-epileptic seizures. Conclusion Our findings suggest that serum prolactin level increases after an epileptic seizure, but not after a non-epileptic seizure. Post-ictal prolactin elevation within 2 hours may be useful in differentiating epileptic seizures from non-epileptic seizures.

    Full Text Available Background Serum prolactin level has been used as a marker to differentiate epileptic from non-epileptic seizures in adults. Electroencephalogram (EEG examination is the primary diagnostic tool used to assess seizures. However, EEGs are quite difficult to perform in children and have sensitivity of only 50%- 55%, with 96% specificity. Objective To assess the diagnostic potential of serum prolactin level as an alternative tool for children for differentiating between epileptic and non-epileptic seizures. Methods This diagnostic study was performed between January 2013 and December 2013. Thirty patients aged 3 months to 15 years with seizures and without fever who visited the Emergency Department of Arifin Ahmad Hospital, Pekanbaru, Riau, were included. Blood specimens were collected within 2 hours after seizure. Subjects underwent serum prolactin measurements and EEG examinations. Results Fifteen subjects had normal EEGs and 15 subjects had abnormal EEGs. Post-ictal serum prolactin levels were significantly higher in the epileptiform EEG group. The mean serum prolactin levels were 23.78 (SD 21.86 ng/mL and 10.57 (SD 5.62ng/mL in patients with epileptic and non-epileptic patients, respectively. Using a prolactin cut-off point of 17.2 ng/mL, serum prolactin had a 73.3% sensitivity and 93.3% specificity for differentiating between epileptic and non-epileptic seizures. Conclusion Our findings suggest that serum prolactin level increases after an epileptic seizure, but not after a non-epileptic seizure. Post-ictal prolactin elevation within 2 hours may be useful in differentiating epileptic seizures from non-epileptic seizures.

    Full Text Available Abstract Background Glutathione S-transferases (GSTs play an important role in metabolizing anti-epileptic drugs (AEDs in liver. Expressions of GSTs in brain, which may result in poor efficacy of AEDs, have not been well studied. Using clinical cortex specimen from 32 intractable epileptic subjects and 8 non-epileptic controls, the present study investigated the correlation between GSTs and intractable epilepsy. Results Three different GST isoforms (α, μ, and π were detected with immunohistochemistry. GST-α expression was not seen in any cortex specimens. Sixty three percent (63% of control and 53% of intractible epileptic specimens showed GST-μ immunoreactivity. No significant difference in intensity of GST-μ staining was observed between these two groups. GST-π expression was found in endothelial cells and glial cells/astrocytes. Fifty percent (50% of the control patients and 66% of the epileptic patients were GST-π positive. The grading of epileptic patients was significantly higher than that of control patients (p Conclusion High levels of GST-π in endothelial cells and glial cells/astrocyte correlate to medical intractable epilepsy, suggesting that GST-π contributes to resistance to AED treatment.

    Full Text Available Objective: to evaluate the efficacy of injectable valproate (convulex in patients with serial epileptic seizures and status epilepticus (SE at the prehospital stage.Patients and methods. Thirty-two adult patients, including 17 (53% men and 15 (47% women, were examined. Most patients were aged over 40 years (mean age 54.7±9.4 years. To define the required dose of the drug, the authors estimated the patient's weight that averaged 76.8±1.9 kg, i.e. there was a preponderance of patients who needed convulex, more than 500 mg, to achieve a therapeutic effect.Results. It was impossible to reliably and validly evaluate the type of a seizure as the medical emergency team (MET generally observed the patient with a just evolving seizure and the medical history data were not always valid therefore the type of convulsions and the type of a seizure were evaluated. In most cases, solitary convulsive attacks (tonic and/or clonic convulsions and/or serial seizures were observed in 12 (37.5% and 14 (43.7% patients, respectively; SE was recorded in 6 (8.8% patients. Generalized seizures (without a clear focal onset were prevalent in 24 (75% patients while 8 (25% patients were found to have partial seizures (seizure onset lateralization, a focal onset. According to the pattern of convulsions, seizures may be classified into three types: tonic-clonic, clonic, and tonic in 22 (68.8%, 7 (21.9%, and 3 (9.3% patients, respectively. Analysis of the efficacy of intravenously injectable valproate (convulex in the group of patients with SE and epileptic seizures indicated that complete cessation of seizures could be achieved in 68.8%, their rate decreased in other 9.4% of the patients. Seizures were preserved in 7 (21.8% cases, which required additional administration of drugs. Conclusion. Injectable valproic acid (convulex has a high efficacy and may be preclinically used as the drug of choice to arrest SE and serial seizures caused by both epilepsy and other

    Previous cognitive behavioral studies based on Acquired Equivalence Associative learning Task (AEALT) showed a strong relation between hippocampus and basal ganglia in associative learning. However, experimental behavioral studies of patients with Generalized Tonic Clonic (GTC) epilepsy remained sparse. The aim of the present study is to integrate a classical behavioral cognitive analysis with a computational model approach to investigate cognitive associative learning impairments in patients with GTC epilepsy. We measured the accuracy of associative learning response performance in five GTC epileptic patients and five control subjects by using AEALT, all subjects were matched in age and gender. We ran the task using E-Prime, a neuropsychological software program, and SPSS for data statistical analysis. We tested whether GTC epileptic patients would have different learning performance than normal subjects, based on the degree and the location of impairment either in basal ganglia and/or hippocampus. With the number of patients that was available, our behavioral analysis showed no remarkable differences in learning performance of GTC patients as compared to their control subjects, both in the transfer and acquisition phases. In parallel, our simulation results confirmed strong connection and interaction between hippocampus and basal ganglia in our GTC and their control subjects. Nevertheless, the differences in neural firing rate of the connectionist model and weight update of basal ganglia were not significantly different between GTC and control subjects. Therefore, the behavioral analysis and the simulation data provided the same result, thus indicating that the computational model is likely to predict cognitive outcomes.

    We analyzed the imaging features of transient focal lesions in the splenium of the corpus callosum (SCC) in non-epileptic patients receiving antiepileptic drugs (AEDs). We identified signal abnormalities in the SCC in three non-epileptic patients, all of them receiving AEDs. We examined two of these patients with multiplanar magnetic resonance (MR) imaging using 1.0-T equipment including fluid-attenuated inversion recovery (FLAIR), T2-weighted (TSE) and T1-weighted (SE) sequences before and after injection of contrast agent. The third patient was studied using 1.5-T equipment with the same sequences. Additionally, a T1 SE sequence with a magnetization transfer contrast pulse off resonance (T1 SE/MTC), diffusion-weighted imaging (EPI-DWI) and apparent diffusion coefficient (ADC) maps were obtained. We observed an identical pattern of imaging abnormalities in all patients characterized by round lesions, hyperintense on FLAIR and hypointense on T1 SE images, located in the central portion of the SCC. One lesion showed homogeneous gadolinium enhancement and perilesional vasogenic edema. This particular lesion showed restricted diffusion confirmed on the ADC map. This pattern was considered consistent with focal demyelination. Follow-up MR examinations showed complete disappearance or a clear reduction in lesion size. All patients had been treated with AEDs, but they did not show any clinical signs of toxicity, interhemispheric symptoms, or abnormal neurological findings (including seizures). (orig.)

    A 28-year-old male with dentatorubral pallidoluysian atrophy (DRPLA) was scheduled for evulsion of bone marrow nail after tibia fracture. He was diagnosed as having DRPLA at the age of 12. Although he was receiving anticonvulsants, regular seizures had occurred occasionally and his symptoms were exacerbating. General anesthesia was induced and maintained with intravenous propofol supplemented with fentanyl, nitrous oxide, and oxygen. The operation was performed uneventfully. After the surgery, his breathing was depressed and naloxone was administered to reverse the depression. Thereafter, generalized tonic seizure associated with involuntary movement of the left arm occurred. These symptoms ceased soon after rapid injection of diazepam. Inhaled and intravenous anesthetics have been alleged to have both proconvulsant and anticonvulsant activities in humans. In the present patient with DRPLA, propofol, fentanyl, nitrous oxide, naloxone, and neostigmine administered might be factors, which could have lowered the threshold for seizure activity. Further, patients with DRPLA might have decreased GABA in the basal ganglia, and anesthetics would affect GABA receptors. Thus we should be aware of occurrence of convulsion in DRPLA patients during and after anesthesia.

    Valproic acid (VPA) is an antiepileptic drug that has been associated with impaired hemostasis and increased risk for postsurgical bleeding. However, the published reports provide controversial results. We measured parameters of primary hemostasis in VPA-treated patients with epilepsy, focusing on adenosine nucleotide-dependent platelet responses, which play a central role in primary hemostasis. We enrolled 20 cases (epileptic patients receiving treatment with VPA) and 20 controls (12 epileptic patients receiving treatment with drugs different from VPA and 8 healthy subjects). Measurements included prothrombin time (PT), activated partial thromboplastin time (APTT), platelet count, platelet function analyzer (PFA)-100 closure times, plasma von Willebrand factor levels, platelet content of ADP, ATP, and serotonin (all stored in platelet dense granules), and platelet shape change and aggregation induced by ADP and other platelet agonists, including the ATP analog α,β-methylene-ATP. The plasma concentration of VPA was in the therapeutic range in 17 patients and slightly above the upper limit in 3 patients. There were no statistically significant differences in any of the studied parameters in cases versus controls. Our thorough controlled study failed to show that chronic treatment with VPA induces significant abnormalities of coagulation and primary hemostasis. Therefore, VPA, when present in the circulation in the therapeutic range, does not impair hemostasis.

    Periodic attacks of uncertain origin, where the clinical presentation resembles epilepsy but there is no evidence of a somatic disease, are called Pseudo-Epilepsy or Pseudo-Epileptic Attack Disorder (PEAD). PEAD may be called a 'non-disease', i.e. a disorder on the fringes of established disease patterns, because it lacks a rational pathophysiological explanation. The first aim of this article is to criticize the idea, common in medical science, that diseases are real entities which exist separately from the patient, waiting to be discovered by the doctor. We argue that doctor and patient construct a disease, and that the construction of the disease PEAD includes many normative evaluations. The second aim is to provide insight into the suffering of patients with PEAD. We focus on three aspects of the patient, identity, autonomy and responsibility. We present some characteristic descriptions of (pseudo-)epileptic attacks by Fjodor Dostoevsky, Gustave Flaubert and Thomas Mann. We argue that diagnosing PEAD reduces a meaningful life event into an insignificant, though intriguing, medical phenomenon, and that the patient will not benefit from being diagnosed as having PEAD.

    The hippocampus is a seminal structure in the most common surgically-treated form of epilepsy. Accurate segmentation of the hippocampus aids in establishing asymmetry regarding size and signal characteristics in order to disclose the likely site of epileptogenicity. With sufficient refinement, it may ultimately aid in the avoidance of invasive monitoring with its expense and risk for the patient. To this end, a reliable and consistent method for segmentation of the hippocampus from magnetic resonance imaging (MRI) is needed. In this work, we present a systematic and statistical analysis approach for evaluation of automated segmentation methods in order to establish one that reliably approximates the results achieved by manual tracing of the hippocampus.

    Full Text Available Epilepsy is a common neurological disorder with recurrent seizures due to a chronic underlying process. Despite tremendous advances in the field of understanding regarding the etio-pathogenesis of epilepsy, phenytoin still remains the drug of choice in its management. Chronic administration of phenytoin has been associated to have a number of adverse effects. Gingival enlargement is one such most often reported adverse drug sequela of long term phenytoin usage with exclusion of local factors contributing towards gingival enlargement. This review gives an overview regarding the association of phenytoin and gingival enlargement seen in epileptic patients being treated with phenytoin.

    We present a pilot study of an application of consistent biclustering to analyze scalp EEG data obtained from epileptic patients undergoing treatment with a vagus nerve stimulator (VNS). The ultimate goal of this study is to develop a physiologic marker for optimal VNS parameters (e.g. output current, signal frequency, etc.) using measures of scalp EEG signals. A time series of STLmax values was computed for each scalp EEG channel recorded from two epileptic patients and used as a feature of the two datasets. The averaged samples from stimulation periods were then separated from averaged samples from non-stimulation periods by feature selection performed within the consistent biclustering routine. The obtained biclustering results allow us to assume that signals from certain parts of the brain consistently change their characteristics when VNS is switched on and could provide a basis for desirable VNS stimulation parameters. A physiologic marker of optimal VNS effect could greatly reduce the cost, time, and risk of calibrating VNS stimulation parameters in newly implanted patients compared to the current method of clinical response.

    The differential diagnosis of epileptic seizures (ES) and psychogenic non-epileptic seizures (PNES) is often difficult. The diagnostic gold standard is video-EEG, but this procedure is limited because of its high cost and is not always available. Research groups from Germany and Britain have used conversation analysis (CA) of patients' descriptions of their seizures as a means of differentiating the type of seizure. The aim of this study was to verify the value of their considerations in relation to the Italian language. Ten subjects (five with ES and five with PNES) diagnosed by means of the video-EEG recording of one seizure were studied under blind conditions by a linguist. The patients with ES described their seizures in as much detail as possible and tried to reconstruct the experience as fully as they can, making an effort to describe their subjective symptoms, quantify the duration of the phases preceding and following the seizure, and use the image of an external entity overcoming them. On the contrary, the patients with PNES repeated their extraneousness to the events that occur, refused to reply, expressed amnesia, reconstructed the happening by referring to descriptions provided by witnesses, and often describe their seizures using the image of an internal entity of which they were victims. The linguist correctly identified nine cases out of ten using CA.

    The course of myoclonic astatic epileptic syndrome (MAES) is variable and little information is available about cortical functions in the presence of the disease. The objective of the present study was to assess the phonological working memory (PWM) and the verbal language of six patients between 8 and 18 years old, on treatment for at least 5 years, and good control of seizures, diagnosed in the Service of Epilepsy of Hospital of Clinics of Ribeirão Preto, São Paulo University in Brazil. The Test of Repetition of Meaningless Words was used to assess PWM. Video-recorded of language samples were collected during spontaneous and directed activities for the study of verbal language and pragmatics. A qualitative analysis showed that all patients presented deficits in the execution of the PWM test and only one patient showed poor mastery of all aspects studied. These finds contribute to strategies of treatment for language problems of patients with MAES, focusing on PWA.

    Epilepsy is a chronic brain dysfunction syndrome and nervous system disease whose pathogenesis remains to be determined. The aim of the present study was to analyze the correlation between secondary thrombosis and the serum levels of folate and vitamin B12 in epileptic patients, as well as to determine whether the supplementation of folate and vitamin B12 was associated with a decreased incidence of thrombosis, and provide the basis for novel clinical treatment. A total of 37 patients, diagnosed as epileptic with secondary thrombosis between April 2012 and April 2014, were included in the treatment group. A total of 37 epileptic patients without secondary thrombosis were included in the control group. The serum levels of homocysteine, folate and vitamin B12 in the two groups and in the epileptic patients with intracranial thrombosis or peripheral thrombosis were compared. According to the Guidance of Epilepsy, the patients in the two groups were administered antiepileptic drugs (AEDs) with the supplementation of folate tablet (0.4 mg/day) and vitamin B12 tablet (100 µg/day). These indicators and the incidence of thrombosis in the two groups were compared after 1 year. The serum levels of homocysteine in the two groups were higher than normal, and the levels in the treatment group were significantly higher than those in the control group. The serum levels of folate and vitamin B12 in the treatment group were significantly higher than those in the control group and the difference was statistically significant (PB12 were not associated with the serum level of homocysteine (P>0.05). The logistic regression analysis revealed that the serum levels of folate and vitamin B12 were independent risk factors for epilepsy with secondary thrombosis [folate: odds ratio (OR)=0.635, P=0.038; vitamin B12: OR=0.418, P=0.042]. The differences in the serum levels of homocysteine, folate and vitamin B12 in the epileptic patients with intracranial thrombosis or peripheral thrombosis

    Epilepsy can be defined as a paroxysmal, excessive, neuronal discharge within the brain originating from either cortical or sugcortical regions. The incidence of epilepsy is increasing possibly due to the survival of persons who should have died of brain injuries or other cerebral abnormalities acquired in early life. The use of antibiotics and improvement in the medical care have saved many children who might have died of meningitis, brain abscess, encephalitis, severe head injuries, etc. CCT scan is new radiologic procedure for defining cranial and intracranial structures and also an useful procedure for evaluation and follow-up (FU) of patient with focal seizure disorder. Recently we experienced nodules which were isodense or hypodense on initial non contrasted CT (NECT) and scans became hyperdense of the enhancement in 4 cases of focal epileptic seizure. Nearly complete disappearance or regression of the epileptic foci occurred on the FU CT scans in 2 cases. Operation was performed in 2 cases. The tissue specimen obtained from the CT nodule revealed cerebral edema in one case and localized gliosis and congestion in the other. All the patients showed marked clinical improvement when the CT nodule improved. Review of literature failed to disclose any previous report on such observation.

  9. Analysis of Epileptic Discharges from Implanted Subdural Electrodes in Patients with Sturge-Weber Syndrome.

    Yasushi Iimura

    Full Text Available Almost two-thirds of patients with Sturge-Weber syndrome (SWS have epilepsy, and half of them require surgery for it. However, it is well known that scalp electroencephalography (EEG does not demonstrate unequivocal epileptic discharges in patients with SWS. Therefore, we analyzed interictal and ictal discharges from intracranial subdural EEG recordings in patients treated surgically for SWS to elucidate epileptogenicity in this disorder.Five intractable epileptic patients with SWS who were implanted with subdural electrodes for presurgical evaluation were enrolled in this study. We examined the following seizure parameters: seizure onset zone (SOZ, propagation speed of seizure discharges, and seizure duration by visual inspection. Additionally, power spectrogram analysis on some frequency bands at SOZ was performed from 60 s before the visually detected seizure onset using the EEG Complex Demodulation Method (CDM.We obtained 21 seizures from five patients for evaluation, and all seizures initiated from the cortex under the leptomeningeal angioma. Most of the patients presented with motionless staring and respiratory distress as seizure symptoms. The average seizure propagation speed and duration were 3.1 ± 3.6 cm/min and 19.4 ± 33.6 min, respectively. Significant power spectrogram changes at the SOZ were detected at 10-30 Hz from 15 s before seizure onset, and at 30-80 Hz from 5 s before seizure onset.In patients with SWS, seizures initiate from the cortex under the leptomeningeal angioma, and seizure propagation is slow and persists for a longer period. CDM indicated beta to low gamma-ranged seizure discharges starting from shortly before the visually detected seizure onset. Our ECoG findings indicate that ischemia is a principal mechanism underlying ictogenesis and epileptogenesis in SWS.

    2010-10-05

    Lennox-Gastaut syndrome (LGS) is a rare but debilitating pediatric epileptic encephalopathy characterized by multiple intractable seizure types. Treatment of LGS is challenging because of the small number of antiepileptic drugs (AEDs) which are effective for this syndrome, as well as the need for polytherapy in the majority of patients. This review focuses on the treatment of LGS with rufinamide, a recently approved third-generation AED with reported efficacy as adjunctive therapy for LGS. All relevant papers identified through a PubMed search on the treatment of LGS with rufinamide were reviewed. To date, the literature suggests improvements in seizure frequency for pediatric patients with LGS on rufinamide. Rufinamide appears to be especially effective for atonic or drop attack seizures. Rufinamide also displays a favorable adverse event profile compared with the older anticonvulsants, as well as a minimal number of drug interactions, making it a promising option for the adjunctive treatment of seizures associated with LGS.

    Full Text Available Background: Diminished libido and sexual dysfunction are unusually common among male epileptic patients. The most important etiologic factor may be antiepileptic drugs (AEDs-induced androgen deficiency. We compared reproductive hormone levels among men with epilepsy taking various AEDs and normal controls. Methods: Subjects were 59 male epileptic patients who aged 24 ± 5 years. They had been receiving lamotrigine (LTG (n = 17, carbamazepine (CBZ (n = 18, and sodium valproate (VPA (n = 15 for at least 6 months. We also recruited 23 healthy controls. Testosterone, estradiol, dehydroepiandrosterone sulfate (DHEAS, sex hormone binding globulin (SHBG, androstenedione (AND, luteinizing hormone (LH, and follicle stimulating hormone (FSH levels and gonadal efficiency (testosterone/LH were compared between the four groups. The patients and the control group were examined and evaluated for male reproduction by urology and endocrinology services. Results: Subjects receiving CBZ, VPA, and LTG had significantly lower mean testosterone levels than the control group (P < 0.01. In addition, patients receiving LTG had significantly higher mean testosterone levels than CBZ and VPA groups (P < 0.01 and controls (P < 0.05. There were not any significant differences between the groups in mean estradiol levels. The mean and level in VPA was higher than CBZ, LTG, and control groups (P < 0.01. Men receiving CBZ had significantly lower DHEAS levels than the other groups (P < 0.01. Testosterone/LH ratio in the control group was more than other groups (P < 0.01. On the other hand, this value in LTG group was higher than CBZ and VPA groups (P < 0.01. However, CBZ and VPA groups were not significantly different in terms of testosterone/LH ratio. Conclusion: Although the mean levels of reproductive hormones were lower in the LTG group compared to the controls, among traditional antiepileptic drugs, LTG had fewer side effects on reproductive hormones. Therefore, it is a good

    Full Text Available OBJECTIVE: Leptin is considered to be a signal factor that regulates body weight and energy expenditure, and there is a strong correlation between serum leptin concentrations, body mass index, and body fat mass in humans. Our aim in this study was to evaluate the role of leptin in valproic acid (VPA and topiramate (TPM related weight changes in epileptic patients. METHODS: Body mass index is calculated and serum leptin and insulin levels are measured in 56 patients with epilepsy (40 patients taking VPA and 16 patients taking VPA and TPM and in 40 healty control subjects. RESULTS: Obesity was seen in 21 patients (52.5% in VPA treated group, in 15 patients (37.5% in the control group and in only one male (6.3% in VPA and TPM treated group. Body mass index was lower in the group treated with VPA and TPM (p<0.001. Serum leptin concentrations were correlated with the body mass index (r=0.49, p<0.001 and were significantly higher in obese subjects (p<0.001 and in women (p<0.001. Serum leptin levels were significantly lower in patients treated with VPA and TPM (p<0.05. CONCLUSION: High levels of serum leptin in patients taking VPA and significantly low levels of serum leptin in patients taking VPA and TPM in our study are in agreement with the hypotheses that weight changes induced with VPA and TPM are related with the alterations in serum leptin levels.

    BACKGROUND: Seizure frequency is in abnormal distribution, and it is not enough to express the trend of concentration using means, and its median loses a lot of information, thus it lacks of a standard for evaluating the therapeutic effects based on seizure frequency.OBJECTIVE: To establish a method for evaluating the therapeutic effects on anti-epileptic drugs using changes of interval and duration of seizure.DESIGN: A prospective cohort study.SETTING: Zhumadian Psychiatric Hospital.PARTICIPANTS: Outpatients and inpatients suffering from epilepsy attending firstly visited Zhumadian Psychiatric Hospital from June 2001 to June 2002 were enrolled. They were diagnosed as epileptic according to the International Classification of Epileptic Seizure by International League Against Epilepsy (1981) based on the clinical history, physical examination, and investigations. The interval time was no more than 6 months. Informed consent was obtained from all the subjects, and the study was approved by the hospital ethical committee.METHODS: ① For the first visit and each follow-up, the following data were recorded, including general demographic information, seizure type, the date and time of ictus, the duration of ictus, and inducement or situation related, according to which the following indexes could be calculated, including seizure styles,interval, duration, cluster frequency and cluster duration. The information from the first review was noted as annals A. The second interview was taken at the end of the evaluating period; the information from the second review was noted as annals B. The third interview was taken within two weeks after the second one;the information from the third review was noted as annals C. The annals B or the annals C were respectively compared with the annals A in the light of the same types or the same styles of the same patient. Summation of the scores of interval change and duration change of the same type or the same style and 5 of basic score

    Recent findings indicate that changes in synchronization of neural activities underlying sensitization and kindling could be more comprehensively understood using nonlinear methods. With this aim we have examined local synchronization using novel measure of coarse-grained information rate (CIR) in 8 EEG signals recorded at different cortical areas in 44 patients with paranoid schizophrenia. The values of local synchronization that could reflect sensitization related changes in EEG activities of cortical sites were then related to psychometric measures of epileptic-like symptoms and positive and negative schizophrenia symptoms (PANSS). While no significant correlations between CIR and positive and negative symptoms have been found, statistically significant relationships described by Spearman correlation coefficients between CIR indices and results of LSCL-33 have been observed in 7 (of 8) EEG channels (r in the range from 0.307 to 0.374, pschizophrenia.

    Diplopia, blurred vision and colour disturbances are well-known side effects associated with anti-epileptic drugs (AEDs). Farnsworth-Munsell 100-hue colour test (F-100) is an accepted and sensitive tool to detect changes in colour perception. To determine the impact of AEDs upon colour vision, we evaluated 37 consecutive patients with complex partial seizures exposed to monotherapy with phenytoin (PHT, carbamazepine (CBZ) or valproic acid (VPA). All had normal IQ and no congenital disturbances in colour vision or ocular diseases. Twenty normal controls were used for statistical analysis. Thirteen patients were exposed to PHT, 12 to CBZ and 12 to VPA. Visual colour perception was impaired in 30/37 (82%) of the study group. The most significant abnormality was detected in the blue-yellow axis in 10/13 patients exposed to PHT (p < 0.02) and in 8/12 treated with CBZ (p < 0.009). In 8/12 patients taking VPA, no significant abnormality was observed (p < 0.06). None of the studied patients complained of colour vision disturbances. Our findings strongly support the negative effect of AEDs upon colour vision discrimination, most likely due to changes at the retinal processing level. F-100 proved to be very useful to assess early toxicity due to AEDs.

    Non-invasive pulsed arterial spin labeling (PASL) MRI is a method to study brain perfusion that does not require the administration of a contrast agent, which makes it a valuable diagnostic tool as it reduces cost and side effects. The purpose of the present study was to establish the viability of PASL as an alternative to dynamic susceptibility contrast (DSC-MRI) and other perfusion imaging methods in characterizing changes in perfusion patterns caused by seizures in epileptic patients. We evaluated 19 patients with PASL. Of these, the 9 affected by high-frequency seizures were observed during the peri-ictal period (within 5hours since the last seizure), while the 10 patients affected by low-frequency seizures were observed in the post-ictal period. For comparison, 17/19 patients were also evaluated with DSC-MRI and CBF/CBV. PASL imaging showed focal vascular changes, which allowed the classification of patients in three categories: 8 patients characterized by increased perfusion, 4 patients with normal perfusion and 7 patients with decreased perfusion. PASL perfusion imaging findings were comparable to those obtained by DSC-MRI. Since PASL is a) sensitive to vascular alterations induced by epileptic seizures, b) comparable to DSC-MRI for detecting perfusion asymmetries, c) potentially capable of detecting time-related perfusion changes, it can be recommended for repeated evaluations, to identify the epileptic focus, and in follow-up and/or therapy-response assessment.

    Objective: To investigate the knowledge level related to compliance in patients with epilepsy. Methods: Eighty-seven patients with epilepsy were tested in the city of Xi'an with a knowledge questionnaire containing 21 questions related to compliance. Results: Over 39.5% of patients did not know that epilepsy is the result of abnormal firing of neurons, while 29.9% were uncertain or did not realize that epilepsy attacks can bring up accidents such as traffic accidents, drowning and trauma. A total of 36.6% of responders thought that the best therapy for epilepsy could be found in Traditional Chinese Medicine. As many as 36.8% of tested patients were uncertain or did not know that frequent epilepsy attacks can affect their intelligence. Up to 36% were unaware of the possible consequence of sudden withdrawal of anti-epileptic drugs (AED). Among responders, 39.1% did not know the right treatment method of epilepsy. That AED can control seizure attacks were doubted in 57.5% of epileptic patients. Furthermore, 32.2% did not know whether the disease could be cured. Conclusion: In this group of epileptic patients, generally they do not have enough indispensable knowledge to cope with epilepsy. They urgently need for proper health education besides effective AED to control seizure attacks and improve their quality of life.

Treatment of LGS is challenging because of the small number of antiepileptic drugs (AEDs which are effective for this syndrome, as well as the need for polytherapy in the majority of patients. This review focuses on the treatment of LGS with rufinamide, a recently approved third-generation AED with reported efficacy as adjunctive therapy for LGS. All relevant papers identified through a PubMed search on the treatment of LGS with rufinamide were reviewed. To date, the literature suggests improvements in seizure frequency for pediatric patients with LGS on rufinamide. Rufinamide appears to be especially effective for atonic or drop attack seizures. Rufinamide also displays a favorable adverse event profile compared with the older anticonvulsants, as well as a minimal number of drug interactions, making it a promising option for the adjunctive treatment of seizures associated with LGS.Keywords: epilepsy, Lennox-Gastaut syndrome, pediatrics, seizure, rufinamide

    In this paper, a variation of traditional Genetic Programming(GP) is used to model the MagnetoencephaloGram(MEG) of Epileptic Patients. This variation is Linear Genetic Programming(LGP). LGP is a particular subset of GP wherein computer programs in population are represented as a sequence of instructions from imperative programming language or machine language. The derived models from this method were simplified using genetic algorithms. The proposed method was used to model the MEG signal of epileptic patients using 6 different datasets. Each dataset uses different number of previous values of MEG to predict the next value. The models were tested in datasets different from the ones which were used to produce them and the results were very promising.

    Background: Sudden death is reported in patients who had a history of epilepsy and some authors believed that is due to cardiac arrhythmias. Objectives: This study aimed to predict that the epileptic patients are at risk of serious cardiac arrhythmias by QT-nomogram, tachogram (Lorenz), and cardiac restitution plots. Methods: A total number of 71 healthy subjects (Group I) and 64 newly diagnosed epileptic patients (Group II) were recruited from Al-Yarmouk and Baghdad Teaching hospitals in Baghdad from March 2015 to July 2015 and included in this study. The diagnosis of epilepsy achieved clinically, electroencephalograph record and radio-images including computerized tomography and magnetic image resonance. At the time of entry into the study, an electrocardiography (ECG) was done, and the determinants of each ECG record were calculated. The QT-nomogram, tachogram, and cardiac restitution plots were used to identify the patients at risk of cardiac arrhythmias. Results: Significant prolonged corrected QT corrected (QTc) and JT corrected intervals were observed in female compared with male at age ≥50 years while the TQ interval was significantly prolonged in males of Group II. Eight patients of Group II had a significant pathological prolonged QTc interval compared with undetectable finding in Group I. QT nomogram did not disclose significant findings while the plots of Lorenz and restitution steepness disclose that the patients of Group II were vulnerable to cardiac arrhythmias. Abnormal ECG findings were observed in the age extremities (≤18 years and ≥50 years) in Group II compared with Group I. Conclusion: Utilization of QT-nomogram, restitution steepness, and tachogram plots is useful tools for detection subclinical vulnerable epileptic patient with cardiac arrhythmias. PMID:28149075

    Full Text Available The relationship between Toxocara infection and epilepsy was previously demonstrated by several case-control studies and case reports. These previous studies were often based on the enzyme-linked immunosorbent assay (ELISA using Toxocara excretory-secretory antigens, which are not specific due to cross-reactivity with other parasitic infections such as ascariasis, trichuriasis, and anisakiasis. An immunoblot analysis is highly specific and can detect low levels of Toxocara antibodies. Therefore, this assay may be useful in the identification of toxocariasis in epileptic patients. We examined patients who had epilepsy and healthy subjects for seropositivity for Toxocara infection by ELISA and Western blotting. Out of 85 epileptic patients, 10 (11.8% and 3 (3.5% persons exhibited Toxocara immunoglobulin G (IgG antibodies responses by ELISA and by both techniques, respectively. Moreover, in the healthy group (, 3 (3.5% persons were positive by ELISA, but none was detected by Western blotting. This study indicates that Toxocara infection is a risk factor for epilepsy in Iran. These findings strongly suggest the need to perform Western blotting immunodiagnosis, as well as the ELISA using Toxocara excretory-secretory antigens, to improve diagnosis of human toxocariasis in patients with epilepsy.

    Autoantibodies that bind to voltage-gated potassium-channel complex proteins (VGKC-complex antibodies) occur frequently in adults with limbic encephalitis presenting with cognitive impairment and seizures. Recently, VGKC-complex antibodies have been described in a few children with limbic encephalitis, and children with unexplained encephalitis presenting with status epilepticus. We report a case of infantile-onset epileptic spasms and developmental delay compatible with epileptic encephalopathy. Our patient was a female infant, aged 4 months at presentation. She had evidence of immune activation in the central nervous system with elevated cerebrospinal fluid neopterin and mirrored oligoclonal bands, which prompted testing for autoantibodies. VGKC-complex antibodies were elevated (201 pmol/L, normalVGKC-complex antibodies might represent a marker of immune therapy responsiveness in a subgroup of patients with infantile epileptic encephalopathy.

    Full Text Available Anna Kelemen1, Péter Halász21National Institute of Neurosciences, Epilepsy Center, Budapest, Hungary; 2Faculty of Information Technology, Pázmány Péter Catholic University, Budapest, Hungary Abstract: Lacosamide is a newly registered antiepileptic drug with dual mechanisms of action. It selectively enhances slow inactivation of voltage-gated sodium channels, resulting in stabilization of hyperexcitable neuronal membranes and inhibition of repetitive neuronal firing. It also binds to a collapsing-response mediator protein-2, CRMP2. Lacosamide has a favorable pharmacokinetic profile; is rapidly and completely absorbed, has a relatively long elimination half-life of 13 hours which allows twice-daily administration, linear pharmacokinetics, and has low potential for drug interactions and renal elimination. Both oral and intravenous formulations of lacosamide are being developed. In placebo-controlled clinical trials, lacosamide was effective in seizure reduction as adjunctive therapy in patients with uncontrolled partial-onset seizures. Lacosamide was generally well tolerated. The most frequently reported adverse events in placebo-controlled trials were dizziness, headache, nausea, and diplopia. Intravenous lacosamide has a comparably good safety profile.Keywords: lacosamide, epilepsy, partial onset seizures

    Advances in neuroimaging techniques, particularly Magnetic Resonance Imaging (MRI), have proved invaluable in detecting structural brain lesions in patients with epilepsy in developed countries. In Malaysia, a few electroencephalography facilities available in rural district hospitals run by trained physician assistants have Internet connections to a government neurological center in Kuala Lumpur. These facilities are more commonly available than MRI machines, which require radiological expertise and helium replacement, which may problematic in Southeast Asian countries where radiologists are found in mainly big cities or towns. We conducted a cross-sectional study over a two year period begining January 2001 on rural patients, correlating EEG reports and MRI images with a clinical diagnosis of epilepsy to set guidelines for which rural patients need to be referred to a hospital with MRI facilities. The patients referred by different hospitals without neurological services were classified as having generalized, partial or unclassified seizures based on the International Classification of Epileptic Seizures proposed by the International League Against Epilepsy (ILAE). The clinical parameters studied were seizure type, seizure frequency, status epilepticus and duration of seizure. EEG reports were reviewed for localized and generalized abnormalities and epileptiform changes. Statistical analysis was performed using logistic regression and area under the curve. The association between clinical and radiological abnormalities was evaluated for sensitivity and specificity. Twenty-six males and 18 females were evaluated. The mean age was 20.7 +/- 13.3 years. Nineteen (43.2%) had generalized seizures, 22 (50.0%) had partial seizures and 3 (6.8%) presented with unclassified seizures. The EEG was abnormal in 30 patients (20 with generalized abnormalities and 10 localized abnormalities). The MRI was abnormal in 17 patients (38.6%); the abnormalities observed were cerebral

    Tuberous sclerosis (Bourneville-Pringle disease) is a rare disease with a triad of mental retardation, epilepsy, and facial spot. Management of the patients with tuberous sclerosis under general anesthesia has been previously reported. However, there are few case reports about management under general anesthesia of a pediatric patient with tuberous sclerosis with frequent epileptic seizure. Here, we report a case of a pediatric patient with tuberous sclerosis and frequent epileptic seizure who underwent intensive dental treatment under general anesthesia with careful management of epilepsy. The patient was discharged on the day of surgery without any complications. In this case report, we discussed the appropriate assessment of the complications of tuberous sclerosis; such as, of central nervous, circulatory, respiratory, endocrine, and urinary systems including the management of general anesthesia.

    Objective: To determine the health related quality of life (HRQOL) in patients with epilepsy or psychogenic non-epileptic seizures (PNES). Methods: This cross-sectional study was carried out between December 2010 and December 2014 in the Department of Neurology and Psychiatry, Faculty of Medicine, Baskent University, Adana, Turkey. Patients who were admitted for video-electroencephalography monitoring and diagnosed of epileptic seizures or PNES were asked to complete a questionnaire from the World Health Organization Quality of Life, and psychiatric comorbidities were diagnosed using the structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders Fourth Edition. Results: Patients with epilepsy and PNES were found to have similar HRQOL in physical, psychological, social, and environmental domains. However, the percentage of comorbid psychiatric disorders were higher in patients with PNES than patients with epilepsy. Conclusion: Patients with epilepsy and PNES have similar HRQOL, and PNES are resistant to the standard medical therapies used for the treatment of epileptic seizures. The direct lifetime cost of undiagnosed PNES may be of equal with intractable epilepsy. A better understanding of the impact of PNES manifestations and epilepsy would help to provide appropriate clinical, psychological and social care. PMID:26818167

    Neurocysticercosis (NC) is an endemic condition in several areas of Brazil. It is most likely the major responsible for the high prevalence of epilepsy in our country, estimated in 1-2% of general population. We performed a study to evaluate NC as aetiology of epilepsy in the west of Santa Catarina. This state belong to southern Brazil and it has a very developed economy. However, due the widespread swine farming in the west district, many of them without any sanitary control, the national health authorities have considered all this area at risk to NC. The study was carried out in Chapecó, the main town in that region, where CT Scan service was started in 1995. All patients put on hospital care due epileptic seizures in 1995-96 were considered. Febrile convulsions were excluded of the sample. We found a very expressive prevalence rate of NC among patients suffering from epilepsy. Roughly 24% of these patients, showed unequivocal tomography evidences for the diagnosis of NC. Our data suggest cysticercosis as a real endemic trouble in the area and, overdosis of information in proper language, diffuse to the whole population, seems to be the only remedy to fight against it. Moreover, we should pay special attention to everyone related to swine farming, does not matter how this activity has been classified.

    Oxcarbazepine is an anti-epileptic drug, which is almost completely metabolized by cytosolic enzymes in the liver to the active 10-monohyroxy metabolite (MHD) following oral administration. The pharmacokinetic (PK) profiles of MHD were evaluated in pediatric epileptic patients and a possible ethnic difference in PK of MHD between Japanese and non-Japanese pediatric patients was assessed. A non-linear mixed effect modeling approach was used to determine the PK of MHD. A one-compartment population model with first-order absorption appropriately described the PK of MHD. No clinically relevant differences were found for using body surface area or weight to explain between-patient variability, therefore the final model included the effects of body weight on apparent clearance (CL/F) and apparent volume of distribution (V/F) of MHD, and in addition, the effect of 3 concomitant anti-epileptic drugs (carbamazepine, phenobarbital and phenytoin) on CL/F of MHD. Inclusion of ethnicity as a covariate in the final model, concluded no ethnic difference with respect to CL/F of MHD between Japanese and non-Japanese patients. Hence, oxcarbazepine can be generally applied using the same dosage and administration for the treatment of partial onset seizures in pediatric patients, regardless of ethnicity.

    The Rey-Osterrieth Complex Figure (ROCF) is probably one of the most popular measurement instruments of visuoconstructional abilities and nonverbal memory. It is frequently part of neuropsychological test protocols in epilepsy surgery centers. In this study we compared the traditional scoring system of the ROCF developed by Taylor (1998) with a qualitative system that assesses spatial-relational errors devised by Loring et al. [Loring, D. W., Lee, G. P., & Meador, K. J. (1988). Revising the Rey-Osterrieth: Rating right hemisphere recall. Archives of Clinical Neuropsychology, 3, 239-247] in a sample of left and right temporal lobe epilepsy patients undergoing pre-surgical evaluation. We investigated whether the relational-spatial scoring system would be more sensitive to right-sided memory deficits than the traditional Taylor version. There was no difference in the copy phase of the ROCF between the clinical and control groups. There was a significant difference between the control and the clinical groups when the 30-min delayed recall drawings were scored with the Taylor system. However, this system failed to find differences between left and right temporal lobe epileptic patients. On the other hand, comparisons with the qualitative scoring criteria used by Loring et al. [Loring, D. W., Lee, G. P., & Meador, K. J. (1988). Revising the Rey-Osterrieth: Rating right hemisphere recall. Archives of Clinical Neuropsychology, 3, 239-247] revealed that right temporal lobe patients made more spatial-relational errors than patients with left-sided foci. Frequency distribution of these scores for all the three groups and sensitivity and specificity to correctly classify right temporal lobe patients are presented. This investigation demonstrated that applying qualitative, material-specific scoring criteria improves temporal lobe epilepsy presurgical protocols.

    Background: Epilepsy is a chronic disorder characterized by recurrent seizures and has significant psychological and social consequence for everyday living. Epilepsy affects various aspects of ones’ social life. The present study aimed to investigate the influence of marital status on the quality of life of adult Chinese patients with epilepsy. Methods: This study surveyed 805 Chinese adults who have been clinically diagnosed with epilepsy for longer than 1 year in 11 hospitals in Beijing. In this survey, 532 (66.1%) participants were married. All of them completed the case report form with enquiries on demographic data, social factors, and illness. The marriage status of adult epileptic quality of life was the dependent variable, and demographic data and clinical data were independent variables, analyzed through the multiple linear regression analysis methods. The patients’ quality of life was assessed using the Quality of Life in patients with Epilepsy-31 items (QOLIE-31) questionnaire, the Patient Health Questionnaire-9 items (PHQ-9), and the Generalized Anxiety Disorder-7 items (GAD-7). Results: The PHQ-9 and GAD-7 scores in the unmarried group (PHQ-9 = 6.0 and GAD-7 = 5.0) were significantly higher than that of the married group (PHQ-9 = 4.0 and GAD-7 =3.0). The scores of married adult patients with epilepsy on QOLIE (61.8 ± 15.3) and social function (70.9 ± 22.7) were higher than the scores of the unmarried patients aged between 20 and 44 years. The scores of married adult epileptics on the QOLIE (58.4 ± 14.6) and the energy/fatigue (62.1 ± 20.4) were higher than the scores of the unmarried patients (QOLIE = 58.4 ± 14.6 and the energy/fatigue = 62.1 ± 20.4) aged between 45 and 59 years. For the adult epilepsy patients, depression, anxiety, seizures within the last year, disease course, medical expense category, and marriage* age are negatively correlated with the quality of life. Occupation, educational level, and average monthly income are closely

    Full Text Available Using wavelet analysis we have detected the presence of chirps in seizure EEG signals recorded from kindled epileptic rats. Seizures were induced by electrical stimulation of the amygdala and the EEG signals recorded from the amygdala were analyzed using a continuous wavelet transform. A time–frequency representation of the wavelet power spectrum revealed that during seizure the EEG signal is characterized by a chirp-like waveform whose frequency changes with time from the onset of seizure to its completion. Similar chirp-like time–frequency profiles have been observed in newborn and adult patients undergoing epileptic seizures. The global wavelet spectrum depicting the variation of power with frequency showed two dominant frequencies with the largest amounts of power during seizure. Our results indicate that a kindling paradigm in rats can be used as an animal model of human temporal lobe epilepsy to detect seizures by identifying chirp-like time–frequency variations in the EEG signal.

    New generation of healthcare is represented by wearable health monitoring systems, which provide real-time monitoring of patient's physiological parameters. It is expected that continuous ambulatory monitoring of vital signals will improve treatment of patients and enable proactive personal health management. In this paper, we present the implementation of a multimodal real-time system for epilepsy management. The proposed methodology is based on a data streaming architecture and efficient management of a big flow of physiological parameters. The performance of this architecture is examined for varying spatial resolution of the recorded data.

    Full Text Available Assessment of Quality of Life in Epilepsy has currently been emphasized to provide comprehensive care to patients. Aim: To develop and standardize and assess the psychometric properties of Bengali version of QOLIE-10 and to assess the relationship of quality of life with seizure variables and presence of psychiatric morbidity. Design: English QOLIE-10 was translated into Bengali by a translation committee using translation-re-translation technique. Inter-rater reliability between the English and Bengali version was assessed during initial practice session held amongst 20 bilingual patients. It was found that item 3 (related to driving was reported to have difficulty in answering by all the patients as none drove any vehicle. Thus, this item was dropped. The inter-rater reliability of the resultant 9 item scale was found to be high (kappa = 0.9. One hundred and seven epilepsy patients attending the Epilepsy clinic were selected for the study if they met the following criteria: age> 15 years, duration of seizure> 1 year, regular intake of antiepileptic drugs, presence of informant and ability to read Bengali. For each patient, demographic and clinical data (seizure frequency, last seizure date, seizure type as per record, medicine intake history and records of past investigations such as EEG was collected. Each patient were administered QOLIE-9 (Bengali and SRQ-24 Bengali version to screen for psychiatric morbidity. Results: The Cronbach′s Alpha coefficient for QOLIE-9 was 0.81, which did not improve if any item was dropped. All items showed strong correlation with the total score. The instrument showed stable factor structure with three factors (Limitation, Depression, Illness effects. However, the item with regard to memory problem did not fit into any of the factors. The QOLIE-9 total showed a significant correlation with the seizure frequency (r = 0.76FNx08. SRQ positive (i.e., suspected psychiatric morbidity cases had higher QOLIE-9 score

    Tiagabine is an antiepileptic drug used as adjunctive therapy for partial seizures that is believed to selectively inhibit the presynaptic reuptake of gamma aminobutyric acid (GABA). We describe a case of a tiagabine overdose that resulted in status epilepticus (SE) in a patient with no seizure history. A 14-year-old girl with a history of asthma presented with convulsive SE after ingestion of an unknown amount of her sister's tiagabine in a suicide attempt. Attempted anticonvulsant therapy included a total of diazepam 10 mg IV, lorazepam 6 mg IV, pyridoxine 5 g IV, and fosphenytoin 20 mg PE/kg. All were without effect. A computed tomography and electrocardiogram were normal. Continuous bedside EEG monitoring showed suppression of seizure activity following intravenous midazolam. A tiagabine level obtained on ED arrival was 420 ng/mL (therapeutic 20-103 ng/mL). The patient was discharged to psychiatry within 1 week with no neurologic sequelae.

    Cell transplantation has been suggested as an alternative therapy for temporal lobe epilepsy (TLE) because this can suppress spontaneous recurrent seizures in animal models. To evaluate the therapeutic potential of human neural stem/progenitor cells (huNSPCs) for treating TLE, we transplanted huNSPCs, derived from an aborted fetal telencephalon at 13 weeks of gestation and expanded in culture as neurospheres over a long time period, into the epileptic hippocampus of fully kindled and pilocarpine-treated adult rats exhibiting TLE. In vitro, huNSPCs not only produced all three central nervous system neural cell types, but also differentiated into ganglionic eminences-derived γ-aminobutyric acid (GABA)-ergic interneurons and released GABA in response to the depolarization induced by a high K+ medium. NSPC grafting reduced behavioral seizure duration, afterdischarge duration on electroencephalograms, and seizure stage in the kindling model, as well as the frequency and the duration of spontaneous recurrent motor seizures in pilocarpine-induced animals. However, NSPC grafting neither improved spatial learning or memory function in pilocarpine-treated animals. Following transplantation, grafted cells showed extensive migration around the injection site, robust engraftment, and long-term survival, along with differentiation into β-tubulin III+ neurons (∼34%), APC-CC1+ oligodendrocytes (∼28%), and GFAP+ astrocytes (∼8%). Furthermore, among donor-derived cells, ∼24% produced GABA. Additionally, to explain the effect of seizure suppression after NSPC grafting, we examined the anticonvulsant glial cell-derived neurotrophic factor (GDNF) levels in host hippocampal astrocytes and mossy fiber sprouting into the supragranular layer of the dentate gyrus in the epileptic brain. Grafted cells restored the expression of GDNF in host astrocytes but did not reverse the mossy fiber sprouting, eliminating the latter as potential mechanism. These results suggest that human fetal

    We found that all head models provided very similar source locations. In patients having a positive post-operative outcome, at least 74% of the source maxima were within the resection. The median distance from the source maximum to the nearest intracranial electrode showing IED was 13.2, 15.6 and 15.6 mm for LSMAC, BEM and FEM, respectively. The study demonstrates that in clinical applications, the use of highly sophisticated and difficult to implement head models is not a crucial factor for an accurate ESI.

    We investigated the influence of the propagation of extratemporal epileptic seizure activity on the regional increase in cerebral blood flow, which is usually associated with epileptic seizure activity. Forty-two consecutive patients with extratemporal epilepsies were prospectively evaluated. All patients underwent ictal SPET studies with simultaneous electroencephalography (EEG) and video recordings of habitual seizures and imaging studies including cranial magnetic resonance imaging and positron emission tomography with 2-[{sup 18}F]-fluoro-2 deoxy-d-glucose. Propagation of epilptic seizure activity (PESA) was defined as the absence of hyperperfusion on ictal ECD SPET in the lobe of seizure onset, but its presence in another ipsilateral or contralateral lobe. Observers analysing the SPET images were not informed of the other results. PESA was observed in 8 of the 42 patients (19%) and was ipsilateral to the seizure onset in five (63%) of these eight patients. The time between clinical seizure onset and injection of the ECD tracer ranged from 14 to 61 s (mean 34 s). Seven patients (88%) with PESA had parieto-occipital epilepsy and one patient had a frontal epilepsy. PESA was statistically more frequent in patients with parieto-occipital lobe epilepsies (58%) than in the remaining extratemporal epilepsy syndromes (3%) (P<0.0002). These findings indicate that ictal SPET studies require simultaneous EEG-video recordings in patients with extratemporal epilepsies. PESA should be considered when interpreting ictal SPET studies in these patients. Patients with PESA are more likely to have parieto-occipital lobe epilepsy than seizure onset in other extratemporal regions. (orig./MG) (orig.) With 1 fig., 2 tabs., 23 refs.

    Full Text Available The aim of this study was to evaluate the frequency of epilepsy in patients who presented psychogenic non-epileptic seizures (PNES. The evaluation was carried out during intensive VEEG monitoring in a diagnostic center for epilepsy in a university hospital. The difficulties involved in reaching this diagnosis are discussed. Ninety-eight patients underwent intensive and prolonged video-electroencephalographic (VEEG monitoring; out of these, a total of 28 patients presented PNES during monitoring. Epilepsy was defined as present when the patient presented epileptic seizures during VEEG monitoring or when, although not presenting epileptic seizures during monitoring, the patient presented unequivocal interictal epileptiform discharges. The frequency of epilepsy in patients with PNES was 50% (14 patients. Our findings suggest that the frequency of epilepsy in patients with PNES is much higher than that of previous studies, and point out the need, at least in some cases, for prolonging the evaluation of patients with PNES who have clinical histories indicating epilepsy.O objetivo deste estudo foi avaliar a frequência de epilepsia em pacientes que apresentaram crises não epilépticas psicogênicas (CNEP.

    Interictal spikes and sharp waves in human EEG are characteristic signatures of epilepsy. These potentials originate as a result of synchronous pathological discharge of many neurons. The reliable detection of such potentials has been the long standing problem in EEG analysis, especially after long-term monitoring became common in investigation of epileptic patients. The traditional definition of a spike is based on its amplitude, duration, sharpness, and emergence from its background. However, spike detection systems built solely around this definition are not reliable due to the presence of numerous transients and artifacts. We use wavelet transform to analyze the properties of EEG manifestations of epilepsy. We demonstrate that the behavior of wavelet transform of epileptic spikes across scales can constitute the foundation of a relatively simple yet effective detection algorithm.

    Full Text Available Domoic acid epileptic disease is characterized by spontaneous recurrent seizures weeks to months after domoic acid exposure. The potential for this disease was first recognized in a human case study of temporal lobe epilepsy after the 1987 amnesic shellfish-poisoning event in Quebec, and was characterized as a chronic epileptic syndrome in California sea lions through investigation of a series of domoic acid poisoning cases between 1998 and 2006. The sea lion study provided a breadth of insight into clinical presentations, unusual behaviors, brain pathology, and epidemiology. A rat model that replicates key observations of the chronic epileptic syndrome in sea lions has been applied to identify the progression of the epileptic disease state, its relationship to behavioral manifestations, and to define the neural systems involved in these behavioral disorders. Here, we present the concept of domoic acid epileptic disease as a delayed manifestation of domoic acid poisoning and review the state of knowledge for this disease state in affected humans and sea lions. We discuss causative mechanisms and neural underpinnings of disease maturation revealed by the rat model to present the concept for olfactory origin of an epileptic disease; triggered in dendodendritic synapases of the olfactory bulb and maturing in the olfactory cortex. We conclude with updated information on populations at risk, medical diagnosis, treatment, and prognosis.

    2010-10-01

    We report the clinical, EEG and neuroradiologic findings from three adult patients who developed new-onset seizure disorders as early clinical manifestations of de novo high grade glioma. The malignancies could not be recognised at the time of the first epileptic seizure because of minimal non-specific brain abnormalities, which showed no signs of necrosis or significant contrast enhancement on computed tomography and magnetic resonance imaging. Focal EEG abnormalities were recorded in all cases and appeared consistent with the neuroradiologic findings. The patients regained normal neurological status after the first seizure but rapidly developed space-occupying necrotic lesions. Two patients underwent surgery and received histological diagnoses of the tumours. Another patient was finally diagnosed with a malignant glioma based on the neuroradiologic picture and rapid progression of the cerebral lesion. It should be noted that in adult patients, new-onset epileptic seizures might reveal the presence of malignant gliomas at a very early stage in the tumour formation process. This report indicates that typical anatomoradiologic features of de novo high grade glioma, such as necrosis and rim-contrast enhancement, could be absent at the time of the first epileptic seizure but become clear within a short period after clinical presentation.

    Previous research suggests epilepsy and psychogenic non-epileptic seizure (PNES) patients do not show consistent group differences on neuropsychological measures. However, both groups of patients show decreased neuropsychological performance when compared to a normal population (Cragar, Berry, Fakhoury, Cibula, & Schmitt, 2002). Swanson, Springer, Benbadis, and Morris (2000) have suggested epilepsy patients show decreased neurocognitive functioning due to neuropathology whereas PNES patients show decreased neurocognitive functioning due to psychopathology. Effort has also been implicated as an important factor in neuropsychological test results in general (Green, 2003). The purpose of this study was to investigate the relationships of medical history variables (e.g., duration of disorder), neuropathology, psychopathology, and effort to neuropsychological findings in epilepsy and PNES patients. Neuropsychological functioning was divided into six domains: intelligence, memory, language, executive functions, visual-spatial, and motor. Results indicated that medical history variables were related to intellectual, memory, language, and motor functioning. Psychopathology was associated with all cognitive domains except executive functioning. Effort was related to intellectual, memory, language, visual-spatial, and motor functioning. Neuropathology and diagnosis were related only to memory.

  18. [Civil and criminal responsibility of epileptics].

    Science.gov (United States)

    Villanueva, F

    1997-03-01

    Since the new Penal Code has come into force, certain sections have been altered, such as those dealing with exculpatory circumstances, and as specialists treating patients with possible mental changes, we should be aware that section 20 now takes the place of the former section 8. The situation of the epileptic with regard to civil and criminal responsibility, has hardly changed. This is not surprising in view of current clinico-therapeutic knowledge. Epileptic patients are legally able to testify, inherit etc. and also have the obligation to compensate for damage they have caused. An attempt is made to define the immunity from prosecution of epileptics in accordance with non-static criteria, and to use a mixed biological-mental formula, which would make it possible to discover whether there was an alteration or anomaly of mental state at the time of the criminal offence, which would mean that the patient was unable to understand the unlawfulness of his action, or to act in accordance with such understanding. The deed itself is considered, without labelling illnesses or persons, seeking a simple definition of immunity from prosecution. The epileptic is immune from prosecution during a full attack, whilst during the rest of the time each case has to be decided individually. We emphasize the necessity of 'declassifying' epilepsy as a typical endogenous psychosis, which puts these patients into the group of the insane, although this term is no longer included in the new legal code.

    2008-04-01

    As the longevity of all patients with cystic fibrosis (CF) continues to increase (median 2005 survival=36.8 years), more adult patients will be receiving their medical care from nonpediatric adult-care providers. Cystic fibrosis remains a fatal disease, with more than 80% of patients dying after the age of 18 years, and most deaths resulting from pulmonary disease. The changing epidemiology requires adult-care providers to become knowledgeable and competent in the clinical management of adults with CF. Physicians must understand the influence of specific genotype on phenotypic disease presentation and severity, the pathogenic factors determining lung disease onset and progression, the impact of comorbid disease factors such as CF-related diabetes and malnutrition upon lung disease severity, and the currently approved or standard accepted therapies used for chronic management of CF lung disease. This knowledge is critical to help alleviate morbidity and improve mortality for the rapidly expanding population of adults with CF.

    The diagnosis of cystic fibrosis (CF) is being made with increasing frequency in adults. Patients with CF diagnosed in adulthood typically present with respiratory complaints, and often have recurrent or chronic airway infection. At the time of initial presentation individuals may appear to have clinical manifestation limited to a single organ, but with subclinical involvement of the respiratory tract. Adult-diagnosed patients have a good response to CF center care, and newly available cystic fibrosis transmembrane receptor-modulating therapies are promising for the treatment of residual function mutation, thus increasing the importance of the diagnosis in adults with unexplained bronchiectasis.

    Liposteroid was administered intravenously to 6 patients with refractory epileptic spasms. In one case, the spasms initially disappeared but then reappeared after three months. Another case had a transient and slight decrease of epileptic spasms. In the only patient in whom spasms disappeared, EEG abnormalities were greatly improved with diffuse spikes and waves changing into focal spikes. Two cases displayed hyperexcitability, insomnia and acting out behavior, and the therapy was discontinued in one of them. One case had appetite loss and another showed an increase in tonic seizures. No patient had serious adverse effects such as infection, edema, subdural hematoma and brain shrinkage. Although liposteroid therapy has been recommended as an easy, useful and safe alternative for ACTH, we found considerable adverse effects and only a small effect on refractory spasms, and conclude that the regimen should be modified.

    A non-linear support vector machine (NLSVM) seizure classification SoC with 8-channel EEG data acquisition and storage for epileptic patients is presented. The proposed SoC is the first work in literature that integrates a feature extraction (FE) engine, patient specific hardware-efficient NLSVM classification engine, 96 KB SRAM for EEG data storage and low-noise, high dynamic range readout circuits. To achieve on-chip integration of the NLSVM classification engine with minimum area and energy consumption, the FE engine utilizes time division multiplexing (TDM)-BPF architecture. The implemented log-linear Gaussian basis function (LL-GBF) NLSVM classifier exploits the linearization to achieve energy consumption of 0.39 μ J/operation and reduces the area by 28.2% compared to conventional GBF implementation. The readout circuits incorporate a chopper-stabilized DC servo loop to minimize the noise level elevation and achieve noise RTI of 0.81 μ Vrms for 0.5-100 Hz bandwidth with an NEF of 4.0. The 5 × 5 mm (2) SoC is implemented in a 0.18 μm 1P6M CMOS process consuming 1.83 μ J/classification for 8-channel operation. SoC verification has been done with the Children's Hospital Boston-MIT EEG database, as well as with a specific rapid eye-blink pattern detection test, which results in an average detection rate, average false alarm rate and latency of 95.1%, 0.94% (0.27 false alarms/hour) and 2 s, respectively.

    Full Text Available Background: The usefulness of electroencephalography (EEG in predicting seizure recurrence after antiepileptic drugs (AED tapering is a controversial subject. There have been no studies which tested the additional yield of long-term over routine EEG recordings in predicting seizure recurrence after AED withdrawal. Objective: The primary objective of our study is to determine the recurrence rate of seizure following AED withdrawal in patients with focal epilepsy, unknown cause who had normal long-term electroencephalography (LTEEG and secondary objective is to analyze the variables that would predict seizure recurrence. Materials and Methods: This was a prospective observational study. A total of 91 patients were included. 62 patients who had normal routine and LTEEG entered the final phase of the study were followed-up regularly for 1 year or until seizure recurrence whichever was earlier. Results: A total number of 91 patients were enrolled for the first phase of the study. Of these, 13 (14.29% patients had an abnormal routine EEG. Of the remaining patients, another 16 (17.58% had abnormal LTEEG. The remaining 62 patients with normal routine and long-term EEG entered the final phase of the study. Of these, 17 patients (27.41% had seizure recurrence during the follow-up while 45 (72.58% remained seizure free until the end of the 1 year follow-up. The significant variables associated with a higher risk of seizure relapse were a positive past history of seizure recurrence on prior drug withdrawal (relative risk: 2.19, confidence interval: 1.01-4.74, P < 0.05 and the duration of epilepsy until seizure control was achieved (P < 0.009. Conclusions: The recurrence rate of seizure in patients with a normal LTEEG is 27.41%. A positive past history of seizure recurrence and a longer time to achieve seizure freedom with AED increased the risk of seizure recurrence.

  8. Localizing epileptic seizure onsets with Granger causality

    Accurate localization of the epileptic seizure onset zones (SOZs) is crucial for successful surgery, which usually depends on the information obtained from intracranial electroencephalography (IEEG) recordings. The visual criteria and univariate methods of analyzing IEEG recordings have not always produced clarity on the SOZs for resection and ultimate seizure freedom for patients. Here, to contribute to improving the localization of the SOZs and to understanding the mechanism of seizure propagation over the brain, we applied spectral interdependency methods to IEEG time series recorded from patients during seizures. We found that the high-frequency (>80 Hz) Granger causality (GC) occurs before the onset of any visible ictal activity and causal relationships involve the recording electrodes where clinically identifiable seizures later develop. These results suggest that high-frequency oscillatory network activities precede and underlie epileptic seizures, and that GC spectral measures derived from IEEG can assist in precise delineation of seizure onset times and SOZs.

    Sleep paralysis (SP) is a common parasomnia. The diagnostic criteria for SP, as reported in the International Classification of Sleep Disorders, are essentially clinical, as electroencephalography (EEG)-polysomnography (PSG) is not mandatory. We describe a subject whose sleep-related events fulfilled the diagnostic criteria for SP, even though her visual hallucinations were elementary, repetitive and stereotyped, thus differing from those usually reported by patients with SP. Video/EEG-PSG documented the focal epileptic nature of the SP-like episodes.

    The aim of this study was to evaluate the sensitivity of interictal compared to ictal SPECT in the lateralization of the epileptogenic focus in refractory temporal lobe epilepsy (TLE) patients that present with normal magnetic resonance imaging (MRI) or bilateral mesial temporal sclerosis (MTS). Thirty patients with TLE, for whom MRI examinations were normal or who presented with bilateral MTS, were retrospectively studied. Using a confidence interval of 95% and a level of significance for p-value <0.05, an estimated agreement rate of 73% with a minimum agreement rate of 57% was calculated comparing interictal and ictal SPECTs. In conclusion the interictal SPECT is only useful when associated with the ictal SPECT and does not substitute it in the localization of epileptogenic areas in patients with normal MRI or bilateral MTS.

    Full Text Available Introduction. Paroxismal events can resemble epileptic seizures, however, some epileptic seizures, especially benign occipital childhood epilepsies can imitate migraine, cycling vomiting or encephalitis. Objective. The aim of this study was evaluation of clinical and electroencephalographic (EEG features and outcome in children with benign occipital childhood epilepsies. Methods. Investigation included 18 patients with benign occipital childhood epilepsies hospitalized in the period from 2007 to 2010. The diagnosis was based on clinical and EEG characteristics of seizures, while treatment included acute therapy for seizures and chronic antiepileptic drugs. Prognosis was analyzed in terms of neurological outcome and seizure recurrence rate. Results. Benign occipital childhood epilepsy with early onset was diagnosed in 15 children. Vegetative symptoms, mostly ictal vomiting (13, eye deviation and loss of consciousness (13 dominated in the clinical presentation. The most frequent EEG findings showed occipital epileptic discharges. Benign occipital childhood epilepsy with late onset was diagnosed in three cases. Seizures were manifested by visual hallucinations, headache and secondary generalized convulsions. All three patients were administered chronic antiepileptic drugs and had good outcome. Conclusion. In our patients, clinical manifestations of benign occipital epilepsies had some similarities with clinical features of migraine and encephalitis. It could explain misdiagnosis in some of them. Knowledge about main features and differences between each of these disorders is crucial for making appropriate diagnosis.

    It is not easy to determine the location of the cerebral generators and the other brain regions that may be involved at the time of an epileptic spike seen in the scalp EEG. The possibility to combine EEG recording with functional MRI scanning (fMRI) opens the opportunity to uncover the regions of the brain showing changes in metabolism and blood flow in response to epileptic spikes seen in the EEG. These regions are presumably involved in the abnormal neuronal activity at the origin of epileptic discharges. This paper reviews the methodology involved in performing such studies, including the special techniques required for recording the EEG inside the scanner and the statistical issues in analyzing the fMRI signal. We then discuss the results obtained in patients with different types of focal epileptic disorders and in patients with primary generalized epilepsy. The results in general indicate that interictal epileptic discharges may affect brain areas well beyond the presumed region in which they are generated. The noninvasive nature of this method opens new horizons in the investigation of brain regions involved and affected by epileptic discharges.

    Full Text Available Accumulating evidence is emerging that microRNAs (miRs are key regulators controlling neuroinflammatory processes, which are known to play a potential role in the pathogenesis of temporal lobe epilepsy (TLE. The aim of the present study was to investigate the dynamic expression pattern of interleukin (IL–10 as an anti-inflammatory cytokine and miR-187 and post-transcriptional inflammation-related miRNA in the hippocampus of a rat model of status epilepticus (SE and patients with TLE. We performed a real-time quantitative PCR and western blot on rat hippocampus (2 hours, 7 days, 21 days and 60 days following pilocarpine-induced SE, and on hippocampus obtained from TLE patients and normal controls. To detect the relationship between IL-10 and miR-187 on neurons, lipopolysaccharide (LPS and IL-10-stimulated neurons were prepared. Furthermore, we identified the effect of antagonizing of miR-187 by its antagomir on IL-10 secretion. Here we reported that that IL-10 secretion and miR-187 expression levels are inversely correlated after SE.. In patients with TLE, the expression levels of IL-10 was also significantly upregulated, whereas miR-187 expression was significantly downregulated. Moreover, miR-187 expression was significantly reduced following IL-10 stimulation in an IL-10–dependent manner. On the other hand, antagonizing miR-187 reduced the production of IL-10 in hippocampal tissues of rat model of SE. Our findings demonstrate a critical role of miR-187 in the physiological regulation of IL-10 anti-inflammatory responses and elucidate the role of neuro-inflammation in the pathogenesis of TLE. Therefore, modulation of the IL-10 / miR-187 axis may be a new therapeutic approach for TLE.

    BACKGROUND: Researchers discovered that serum prolactin could rise following an epileptic seizure. The prolactin level might reach three times more than basic level within 30 minutes and decrease to the normal value 2 hours after the seizure occurred. The mechanism might result in an increase of serum prolactin concentrations with the activation of the hypothalamic-pituitary axis.OBJ ECTIVE:To probe into the correlation between changes of serum prolactin and incidence of epileptic discharges of electroencephalogram (EEG) at 24-36 hours after epileptic onset of patients with secondary epilepsy.DESIGN: Clinical observational study.SETTING: Department of Neurology, First Hospital affiliated to Soochow University.PARTICIPANTS: A total of 21 patients with secondary epilepsy were selected from the Department of Neurological Emergency or Hospital Room of the First Hospital affiliated to Soochow University from November 2005 to April 2006. There were 14 males and 7 females aged from 25 to 72 years. All patients met International League Anti-epileptic (ILAE) criteria in 1981 for secondary generalized tonic clonic seizure through CT or MRI and previous EEG. All patients were consent. Primary diseases included cerebral trauma (3 cases),tumor (2 cases), stroke (7 cases) and intracranial infeion (9 cases).METHODS: Venous blood of all patients was collected at 24-36 hours after epileptic onset. Serum prolactin kit (Beckman Coulter, Inc in USA) was used to measure value of serum prolactin according to kit instruction.Then, value of serum prolactin was compared with the normal value (male: 2.64-13.13 mg/L; female: 3.34-26.72 mg/L); meanwhile, EEG equipment (American Nicolet Incorporation) was used in this study.MAIN OUTCOME MEASURES: ① Abnormal rate of serum prolactin of patients with secondary epilepsy; ②Comparison between normal and abnormal level of serum prolactin and incidence of EEG epileptic discharge of patients with secondary epilepsy.RESULTS :All 21 patients with

    Full Text Available Treating women affected by epilepsy during pregnancy is challenging.  Clinicians have to consider both the teratogenic effects of Antiepileptic Drugs (AEDs and the risk of seizure recurrence. Pharmacokinetic changes during pregnancy are rapid and conspicuous so that the serum concentration of drugs can be modified and the effectiveness of AEDs cannot be guaranteed. The aim of this study is to evaluate the risk of Major Congenital Malformation (MCM associated with AEDs treatment during the first trimester of pregnancy. We collected data from 338 patients who contacted the Teratology Information Services of XXX University Hospital and we found that only the variable monotherapy vs politherapy had statistical significance for MCM. More studies are needed to assess the efficacy and safety of newer AEDs.

    Fluorine-18 fluoroethylflumazenil ([{sup 18}F]FEF) is a tracer for central benzodiazepine (BZ) receptors which is proposed as an alternative to carbon-11 flumazenil for in vivo imaging using positron emission tomography (PET) in humans. In this study, [{sup 18}F]FEF kinetic data were acquired using a 60-min two-injection protocol on three normal subjects and two patients suffering from mesiotemporal epilepsy as demonstrated by abnormal magnetic resonance imaging and [{sup 18}F]fluorodeoxyglucose positron emission tomography. First, a tracer bolus injection was performed and [{sup 18}F]FEF rapidly distributed in the brain according to the known BZ receptor distribution. Thirty minutes later a displacement injection of 0.01 mg/kg of unlabelled flumazenil was performed. Activity was rapidly displaced from all BZ receptor regions demonstrating the specific binding of [{sup 18}F]FEF. No displacement was observed in the pons. Plasma input function was obtained from arterial blood sampling, and metabolite analysis was performed by high-performance liquid chromatography. Metabolite quantification revealed a fast decrease in tracer plasma concentration, such that at 5 min post injection about 70% of the total radioactivity in plasma corresponded to [{sup 18}F]FEF, reaching 24% at 30 min post injection. The interactions between [{sup 18}F]FEF and BZ receptors were described using linear compartmental models with plasma input and reference tissue approaches. Binding potential values were in agreement with the known distribution of BZ receptors in human brain. Finally, in two patients with mesiotemporal sclerosis, reduced uptake of [{sup 18}F]FEF was clearly observed in the implicated left hippocampus. (orig.)

    Diffuse reflectance and fluorescence spectroscopy are used to detect histopathological abnormalities of an epileptic brain in a human subject study. Static diffuse reflectance and fluorescence spectra are acquired from normal and epileptic brain areas, defined by electrocorticography (ECoG), from pediatric patients undergoing epilepsy surgery. Biopsy specimens are taken from the investigated sites within an abnormal brain. Spectral analysis reveals significant differences in diffuse reflectance spectra and the ratio of fluorescence and diffuse reflectance spectra from normal and epileptic brain areas defined by ECoG and histology. Using these spectral differences, tissue classification models with accuracy above 80% are developed based on linear discriminant analysis. The differences between the diffuse reflectance spectra from the normal and epileptic brain areas observed in this study are attributed to alterations in the static hemodynamic characteristics of an epileptic brain, suggesting a unique association between the histopathological and the hemodynamic abnormalities in an epileptic brain.

    To describe the ictal technetium-99 m-ECD SPECT findings in polymicrogyria syndromes (PMG) during epileptic seizures. We investigated 17 patients with PMG syndromes during presurgical workup, which included long-term video-electroencephalographic (EEG) monitoring, neurological and psychiatry assessments, invasive EEG, and the subtraction of ictal-interictal SPECT coregistered to magnetic resonance imaging (MRI) (SISCOM). The analysis of the PMG cortex, using SISCOM, revealed intense hyperperfusion in the polymicrogyric lesion during epileptic seizures in all patients. Interestingly, other localizing investigations showed heterogeneous findings. Twelve patients underwent epilepsy surgery, three achieved seizure-freedom, five have worthwhile improvement, and four patients remained unchanged. Our study strongly suggests the involvement of PMG in seizure generation or early propagation. Both conventional ictal single-photon emission computed tomography (SPECT) and SISCOM appeared as the single contributive exam to suggest the localization of the epileptogenic zone. Despite the limited number of resective epilepsy surgery in our study (n = 9), we found a strong prognostic role of SISCOM in predicting surgical outcome. This result may be of great value on surgical decision-making of whether or not the whole or part of the PMG lesion should be surgically resected. (orig.)

Methods VA and Medicare databases were used to identify veterans 66 years and older, who received a care from the VA between 1999 and 2004, and b an incident AED (monotherapy prescription. Previously validated ICD-9-CM codes were used to identify suicidal ideation or behavior (suicide-related behaviors cases, epilepsy, and other conditions previously associated with suicide-related behaviors. Each case was matched to controls based on prior history of suicide-related behaviors, year of AED prescription, and epilepsy status. Results The strongest predictor of suicide-related behaviors (N = 64; Controls N = 768 based on conditional logistic regression analysis was affective disorder (depression, anxiety, or post-traumatic stress disorder (PTSD; Odds Ratio 4.42, 95% CI 2.30 to 8.49 diagnosed before AED treatment. Increased suicide-related behaviors were not associated with individual AEDs, including the most commonly prescribed AED in the US - phenytoin. Conclusion Our extensive diagnostic and treatment data demonstrated that the strongest predictor of suicide-related behaviors for older patients newly treated with AED monotherapy was a previous diagnosis of affective disorder. Additional, research using a larger sample is needed to clearly determine the risk of suicide-related behaviors among less commonly used AEDs.

    Pallister-Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by tetrasomy 12p mosaicism associated with a supernumerary isochromosome. Craniofacial dysmorphism, learning impairment and seizures are considered characteristic. However, little is known of the seizure and epilepsy patterns seen in PKS. To better define the occurrence and nature of epileptic and non-epileptic paroxysmal events in PKS, we describe our experience with 5 patients and compare their features with data from a larger cohort of PKS patients ascertained via a web-based parental questionnaire. Three of the 5 patients have had definite epileptic seizures, and one other has had paroxysmal events as yet not clarified. Four of the 5 have also had either non-epileptic paroxysmal events or episodes of uncertain nature. In those with epilepsy, all have had some period of relatively refractory seizures, all have required more than one antiepileptic drug, but none experienced status epilepticus. Only one of the patients with epilepsy (the oldest) has gone into remission. In two of the four with non-epileptic events, video-electroencephalographic monitoring has been valuable in clarifying the nature of the events. EEG characteristics include a slow dominant frequency as well as generalized and focal epileptiform features. Brain MRI findings can be normal but are variable. These specific findings correspond well to information reported by parents in a larger cohort of 51 individuals with PKS. Better understanding of the nature of epileptic and non-epileptic events in PKS will result from a more detailed analysis of objective data obtained from this larger cohort, and from deeper understanding of the molecular impact of 12p tetrasomy in selected cell lines.

    Glaucoma is a potentially blinding disease that affects millions of people worldwide. The mainstay of treatment is lowering of intraocular pressure (IOP) through the use of medications, laser and/or incisional surgery. The trabecular meshwork (TM) is thought to be the site of significant resistance to aqueous outflow in open angle glaucoma. Theoretically, an incision through TM or TM removal should decrease this resistance and lead to a significant reduction in IOP. This approach, commonly referred to as goniotomy or trabeculotomy, has been validated in the pediatric population and has been associated with long-term IOP control. In adults, however, removal of TM tissue has been historically associated with more limited and short-lived success. More recent evidence, reveals that even adult patients may benefit significantly from removal of diseased TM tissue and can lead to a significant reduction in IOP that is long-lasting and safe. In this review, we discuss current evidence and techniques for ab interno trabeculectomy using various devices in the adult patient.

  8. The neural correlates of altered consciousness during epileptic seizures.

    2009-06-01

    Epileptic seizures are characterized by a multifaceted spectrum of alterations in the general level of awareness and/or the subjective contents of consciousness. Complete loss of consciousness occurs when epileptic activity involves both cortical and subcortical structures, as in generalized seizures. On the other hand, simple partial seizures can spare both the level and contents of consciousness. Finally, complex partial seizures associated with medial temporal lobe discharges can selectively impair the patient's subjective experiences with variable degrees of responsiveness. The differences in ictal semiology between patients with epilepsy offer unique avenues for understanding the relationship between pathological brain function and altered conscious states.

    Unconscious patients are frequently referred to radiology departments for computed tomography (CT) of the brain. The objectives of these examinations are to define the underlying cause of impaired consciousness and in some cases to determine the severity of associated brain injury. There is often little history available to guide the clinician or radiologist, particularly in patients referred from the casualty department. In this review, we present the typical CT appearances of adult patients presenting with loss of consciousness for CT examination. We focus on the most common abnormalities that are identified in everyday radiological practice, emphasize important diagnostic signs that may enable a confident diagnosis to be made and discuss when further imaging may be warranted.

  10. Predicting epileptic seizures in advance.

    Directory of Open Access Journals (Sweden)

    Negin Moghim

    Full Text Available Epilepsy is the second most common neurological disorder, affecting 0.6-0.8% of the world's population. In this neurological disorder, abnormal activity of the brain causes seizures, the nature of which tend to be sudden. Antiepileptic Drugs (AEDs are used as long-term therapeutic solutions that control the condition. Of those treated with AEDs, 35% become resistant to medication. The unpredictable nature of seizures poses risks for the individual with epilepsy. It is clearly desirable to find more effective ways of preventing seizures for such patients. The automatic detection of oncoming seizures, before their actual onset, can facilitate timely intervention and hence minimize these risks. In addition, advance prediction of seizures can enrich our understanding of the epileptic brain. In this study, drawing on the body of work behind automatic seizure detection and prediction from digitised Invasive Electroencephalography (EEG data, a prediction algorithm, ASPPR (Advance Seizure Prediction via Pre-ictal Relabeling, is described. ASPPR facilitates the learning of predictive models targeted at recognizing patterns in EEG activity that are in a specific time window in advance of a seizure. It then exploits advanced machine learning coupled with the design and selection of appropriate features from EEG signals. Results, from evaluating ASPPR independently on 21 different patients, suggest that seizures for many patients can be predicted up to 20 minutes in advance of their onset. Compared to benchmark performance represented by a mean S1-Score (harmonic mean of Sensitivity and Specificity of 90.6% for predicting seizure onset between 0 and 5 minutes in advance, ASPPR achieves mean S1-Scores of: 96.30% for prediction between 1 and 6 minutes in advance, 96.13% for prediction between 8 and 13 minutes in advance, 94.5% for prediction between 14 and 19 minutes in advance, and 94.2% for prediction between 20 and 25 minutes in advance.

    Localization of the epileptogenic zone is an important issue in epileptology, even though there is not a unique definition of the epileptic focus. The objective of the present study is to test ultrametric analysis to uncover cortical interactions in human epileptic data. Correlation analysis has been carried out over intraoperative Electro-Corticography (ECoG) data in 2 patients suffering from temporal lobe epilepsy (TLE). Recordings were obtained using a grid of 20 electrodes (5×4) covering the lateral temporal lobe and a strip of either 4 or 8 electrodes at the mesial temporal lobe. Ultrametric analysis was performed in the averaged final correlation matrices. By using the matrix of linear correlation coefficients and the appropriate metric distance between pairs of electrodes time series, we were able to construct Minimum Spanning Trees (MST). The topological connectivity displayed by these trees gives useful and valuable information regarding physiological and pathological information in the temporal lobe of epileptic patients.

    Hormonal therapy or ketogenic diet often permits overcoming the challenging periods of many epileptic encephalopathies (West and Lennox-Gastaut syndromes and encephalopathy with continuous spike-waves in slow sleep), but relapse affects over 20% of patients. We report here a monocenter pilot series of 42 consecutive patients in whom we combined oral steroids with the ketogenic diet for corticosteroid-resistant or -dependent epileptic encephalopathy. We retrospectively evaluated the effect on seizure frequency, interictal spike activity, neuropsychological course, and steroid treatment course. Twenty-three patients had West syndrome (WS), 13 had encephalopathy with continuous spike-waves in slow sleep (CSWS), and six others had miscellaneous epileptic encephalopathies. All patients succeeded to reach 0.8 to 1.6g/l ketone bodies in the urine following the usual KD regimen. For at least 6 months, 14/42 responded to the addition of the ketogenic diet: 4/23 with WS, 8/13 with CSWS, and 2/6 with miscellaneous epileptic encephalopathies. The addition of the KD allowed withdrawing steroids in all responders. Among them, 10/15 had been patients with steroid-dependent epileptic encephalopathy and 4/27 patients with steroid-resistant epileptic encephalopathy. Therefore, the ketogenic diet can be used successfully in combination with corticosteroids for epileptic encephalopathies. Patients presenting with steroid-dependent CSWS seem to be the best candidates.

    Electroencephalogram (EEG) - the recorded representation of electrical activity of the brain contain useful information about the state of the brain. Recent studies indicate that nonlinear methods can extract valuable information from neuronal dynamics. We compare the dynamical properties of EEG signals of healthy subjects with epileptic subjects using nonlinear time series analysis techniques. Chaotic invariants like correlation dimension (D2) , largest Lyapunov exponent (lambda1), Hurst exponent (H) and Kolmogorov entropy (K) are used to characterize the signal. Our study showed clear differences in dynamical properties of brain electrical activity of the normal and epileptic subjects with a confidence level of more than 90%. Furthermore to support this claim fractal dimension (FD) analysis is performed. The results indicate reduction in value of FD for epileptic EEG indicating reduction in system complexity.

    2013-09-06

    Paroxysmal events in childhood are a challenge for pediatric neurologists, given its highly heterogeneous clinical manifestations, often difficult to distinguish between phenomena of epileptic seizure or not. The non-epileptic paroxysmal episodes are neurological phenomena, with motor, sensory symptoms, and/or sensory impairments, with or without involvement of consciousness, epileptic phenomena unrelated, so no electroencephalographic correlative expression between or during episodes. From the clinical point of view can be classified into four groups: motor phenomena, syncope, migraine (and associated conditions) and acute psychiatric symptoms. In this paper we analyze paroxysmal motor phenomena in awake children, dividing them according to their clinical manifestations: extrapyramidal episodes (paroxysmal kinesiogenic, non kinesiogenic and not related to exercise dyskinesias, Dopa responsive dystonia) and similar symptoms of dystonia (Sandifer syndrome); manifestations of startle (hyperekplexia); episodic eye and head movements (benign paroxysmal tonic upward gaze nistagmus deviation); episodic ataxia (familial episodic ataxias, paroxysmal benign vertigo); stereotyped and phenomena of self-gratification; and myoclonic events (benign myoclonus of early infancy). The detection of these syndromes will, in many cases, allow an adequate genetic counseling, initiate a specific treatment and avoid unnecessary additional studies. Molecular studies have demonstrated a real relationship between epileptic and non-epileptic basis of many of these entities and surely the identification of the molecular basis and understanding of the pathophysiological mechanisms in many of them allow us, in the near future will benefit our patients.

    We consider the electrical signals recorded from a subdural ECoG grid of electrodes placed on the pial surface of the brain for chronic evaluation of epileptic patients before surgical resection. A simple and computationally fast method to analyze the inter-ictal phase synchrony between such electrodes is introduced and developed with the aim of detecting and localizing the foci of the epileptic events. We evaluate the method by comparing the results of surgery to the localization predicted here. We find an indication of good correspondence between the success or failure in the surgery and the agreement between our identification and the regions actually operated on.

    Full Text Available Background. The relationship between sleep and epilepsy has been long ago studied, and several excellent reviews are available. However, recent development in sleep research, the network concept in epilepsy, and the recognition of high frequency oscillations in epilepsy and more new results may put this matter in a new light. Aim. The review address the multifold interrelationships between sleep and epilepsy networks and with networks of cognitive functions. Material and Methods. The work is a conceptual update of the available clinical data and relevant studies. Results and Conclusions. Studies exploring dynamic microstructure of sleep have found important gating mechanisms for epileptic activation. As a general rule interictal epileptic manifestations seem to be linked to the slow oscillations of sleep and especially to the reactive delta bouts characterized by A1 subtype in the CAP system. Important link between epilepsy and sleep is the interference of epileptiform discharges with the plastic functions in NREM sleep. This is the main reason of cognitive impairment in different forms of early epileptic encephalopathies affecting the brain in a special developmental window. The impairment of cognitive functions via sleep is present especially in epileptic networks involving the thalamocortical system and the hippocampocortical memory encoding system.

    We apply chaotic time series analysis (CTSA) to human electroencephalogram (EEG) data. Three epoches were examined: epileptic seizure, non-seizure, and transition from non-seizure to seizure. The CTSA tools were applied to four forms of these data: raw EEG data (e-data), artifact data (f-data) via application of a quadratic zero-phase filter of the raw data, artifact-filtered data (g- data) and that was the residual after subtracting f-data from e-data, and a low-pass-filtered version (h-data) of g-data. Two different seizures were analyzed for the same patient. Several nonlinear measures uniquely indicate an epileptic seizure in both cases, including an abrupt decrease in the time per wave cycle in f-data, an abrupt increase in the Kolmogorov entropy and in the correlation dimension for e-h data, and an abrupt increase in the correlation dimension for e-h data. The transition from normal to seizure state also is characterized by distinctly different trends in the nonlinear measures for each seizure and may be potential seizure predictors for this patient. Surrogate analysis of e-data shows that statistically significant nonlinear structure is present during the non-seizure, transition , and seizure epoches.

In order to discriminate the Healthy and the Epileptic EEGs, an improved method of Multifractal Measure such as Generalized Fractal Dimensions (GFD) is also proposed. Finally we conclude that there are significant differences between the Healthy and Epileptic Signals in the designed method than the GFD through graphical and statistical tools. The improved multifractal measure is very efficient technique to analyze the EEG Signals and to compute the state of illness of the Epileptic patients.

    Full Text Available Objective: to study the presence of comorbidities and to investigate quality of life in patients with main types of epilepsy in relation to age.Patients and methods. The investigation enrolled 150 patients aged 17 to 64 years with idiopathic, cryptogenic, and symptomatic types of epilepsy. The investigators studied the presence of sleep disorders using the questionnaires designed by the Somnology Center, Ministry of Health of Russia, and that of daytime sleepiness by the Epworth Sleepiness Scale, determined the level of anxiety and depression by the Hospital Anxiety and Depression Scale, and assessed the severity of seizures by the National Hospital Seizure Severity Scale. Quality of life was investigated using the QOLIE-89 questionnaire. A cluster analysis was carried out to divide all the patients into three age groups (mean age, 27.3; 30.7; and 37.7 years.Results and discussion. A positive relationship was obtained between some indicators of sleep disorders, level of anxiety, and age. There were significant differences between the above three age groups in the following indicators: sleep disorders; daytime sleepiness; level of anxiety, severity of seizures, and scores of the QOLIE-89 questionnaire (p<0.001. Since the patients suffer from different basic types of epilepsy (cryptogenic, idiopathic, and symptomatic, the findings testify to age as an independent factor that modifies quality of life in epileptic patients.

    Many children with trisomy 18 have apneas from the neonatal period. It has been reported that some children with trisomy 18 have epilepsy, including epileptic apneas. However, no previous report has described epileptic apneas in trisomy 18 neonates. We retrospectively reviewed the clinical records of neonates with trisomy 18 who were born at Anjo Kosei Hospital between July 2004 and October 2013 and investigated whether they had epileptic apneas during the neonatal period and whether antiepileptic drugs (AEDs) were effective for treating them. We identified 16 patients with trisomy 18. Nine patients who died within 3 days of birth were excluded. Five of the remaining seven patients had apneas. All five patients underwent electroencephalograms (EEGs) to assess whether they suffered epileptic apneas. Three of the five patients had EEG-confirmed seizures. In two patients, the apneas corresponded to ictal discharges. In one patient, ictal discharges were recorded when she was under mechanical ventilation, but no ictal discharges that corresponded to apneas were recorded after she was extubated. AEDs were effective for treating the apneas and stabilizing the SpO2 in all three patients. Among neonates with trisomy 18 who lived longer than 3 days, three of seven patients had EEG-confirmed seizures. AEDs were useful for treating their epileptic apneas and stabilizing their SpO2. Physicians should keep epileptic apneas in mind when treating apneas in neonates with trisomy 18.

Results: The regression equation of the results determined by HPLC (X) and FPIA (Y) was y = 1. 8163 + 0. 8407x ( r = 0. 944). The determination results had statistical significance between the two methods (P < 0.05). Conclusion; It should pay attention to the difference of 2 kinds of antiepileptic monitoring by FPIA and HPLC method.

    Background: Autism spectrum disorder (ASD) is often associated with epilepsy. Previous studies have also shown increased rates of electroencephalographic (EEG) alteration in ASD patients without epilepsy. The aim of this study was to compare the rate of intermittent rhythmic delta and theta activity (IRDA/IRTA) events between high-functioning adult patients with ASD and matched healthy controls. Materials and Methods: Routine EEG records of 19 ASD patients and 19 matched controls were screened for IRDA/IRTA using a fully data driven analysis with fixed thresholds. IRDA/IRTA rates before and after hyperventilation (HV) as well as the HV-induced difference in IRDA/IRTA rates (HV difference) were analyzed. For inter-group measures, we used the Wilcoxon rank sum test. Results: Significantly increased HV difference was detected in the ASD group (p = 0.0497). However, the groups showed no difference in IRDA/IRTA rates before HV (p = 0.564) and after HV (p = 0.163). Conclusions: The lack of any group differences regarding IRDA/IRTA before HV might be related to the fact that we only studied non-secondary high-functioning autism in a small sample of epilepsy-free adult patients. A significantly increased HV difference might be regarded as a marker of subtle neuronal network instability possibly causing short-term disturbances via local area network inhibition and long-term effects via epileptic encephalopathy.

    Mozart's sonata for two pianos in D major, K448, has been shown to decrease interictal EEG discharges and recurrence of clinical seizures in both adults and young patients. In this prospective, open-label study, we evaluated the effect of listening to a set of Mozart's compositions, according to the Tomatis method, on sleep quality and behavioral disorders, including auto-/hetero-aggression, irritability, and hyperactivity, in a group of children and adolescents with drug-resistant epilepsy. The study group was composed of 11 outpatients (7 males and 4 females), between 1.5years and 21years of age (mean age: 11.9years), all suffering from drug-resistant epileptic encephalopathy (n=11). All of them had a severe/profound intellectual disability associated with cerebral palsy. During the study period, each patient had to listen to a set of Mozart's compositions 2h per day for fifteen days for a total of 30h, which could be distributed over the day depending on the habits and compliance of each patient. The music was filtered by a device preferably delivering higher sound frequencies (>3000Hz) according to the Tomatis principles. The antiepileptic drug therapy remained unchanged throughout the study period. During the 15-day music therapy, 2 out of 11 patients had a reduction of 50-75% in seizure recurrence, and 3 out of 12 patients had a reduction of 75-89%. Overall, 5 (45.4%) out of 11 patients had a ≥50% reduction in the total number of seizures, while the percentage decrease of the total seizure number (11/11) compared with baseline was -51.5% during the 15-day music therapy and -20.7% in the two weeks after the end of treatment. All responders also had an improvement in nighttime sleep and daytime behavior.

    Epilepsy is one of the most common neurological disorders that greatly impair patients' daily lives. A classifier for automated epileptic EEG detection and patient monitoring can be very important for epilepsy diagnosis and patients' quality of life, especially for rural areas and developing countries where medical resources are limited. This paper describes our development of an accurate and fast EEG classifier that can differentiate the EEG data of healthy people from that of epileptic patients, and also detect patients' status (i.e., interictal vs. ictal). We deployed Probabilistic Neural Network (PNN) and fed it with 38 features extracted from the EEG data. The resulting PNN EEG classifier achieves an impressive accuracy greater than 96 as indicated by cross-validation. This prototype classifier is therefore suitable for automated epilepsy detection/diagnosis and seizure monitoring. It may even facilitate seizure prediction.

    We investigated systemic lupus erythematosus (SLE) patients with epilepsy, a major and organic neurological symptom. Our aim was to test patients for the autoimmune epilepsy-associated antibodies anti-GAD, anti-NMDAR, anti-AMPAR1/2, anti-GABABR and anti-VGKC. We tested sera from ten SLE patients with current or previous episodes of epileptic seizures. In addition, sera were tested for staining on primary hippocampal neurons. The patients' clinical and neuroimaging profile, disease activity and accumulated damage scores and therapeutic regimens administered were recorded, and correlations were evaluated. Patients were negative for all anti-neuronal autoantibodies tested, and showed no staining on primary hippocampal cells, which suggests the absence of autoantibodies against neuronal cell surface antigens. Epileptic seizures were all tonic-clonic, and all patients had high disease activity (mean SLE Damage Acticity Index score 19.3 ± 7.3). Six patients had minor or no brain magnetic resonance imaging findings, and three had major findings. 9/10 patients received immunosuppression for 5 ± 4 months, while anti-convulsive treatment was administered to all patients (4.2 ± 3 years). Our results suggest that the majority of SLE-related epileptic seizures cannot be attributed to the action of a single antibody against neuronal antigens. Studies with larger neuropsychiatric SLE populations and stricter inclusion criteria are necessary to verify these findings.

    Full Text Available Objective: Evaluate the nutrient intake and nutritional status of food in cancer patients admitted to a university hospital, with comparison of adult and older adult age category Methods: Cross-sectional study. This study involved cancer patients admitted to a hospital in 2010. Dietary habits were collected using a Brazilian food frequency questionnaire. Participants were divided in two groups: adults or older adults and in 4-cancer category: hematologic, lung, gastrointestinal and others. Body Mass Index evaluated nutritional status. Results: A total of 86 patients with a mean age of 56.5 years, with 55% males and 42% older adults were evaluated. The older adult category had a higher frequency of being underweight (24.4% vs 16.3%, p < 0.01 and a lower frequency of being overweight (7% vs. 15.1%, p < 0.01 than adults. Both, adult and older adults had a high frequency of smoking, alcohol consumption and physical inactivity. The older adults had lower consumption of calories, intake of iron and folic acid. Inadequacy of vitamin intake was observed in both groups; respectively, 52%, 43%, 95%, 76% and 88% for Vitamin A, C, D, E and folic acid. The older adults had a higher folic acid and calcium inadequacy than the adults (97% vs 82%, p <0.01; 88% vs 72%, p < 0.01. There was no association of micronutrient intake with cancer, nor with nutritional status. Conclusion: The food intake, macro and micronutrients ingestion is insufficient among cancer individuals. Food intake of older adults was inferior, when compared to the adult category. There was a high prevalence of BMI excess in the adult group and a worst nutritional status in the older adult category.

    Full Text Available We report a case of a female patient with refractory complex partial seizures since 15 years of age, recurrent postictal psychotic episodes since 35 which evolved to a chronic refractory interictal psychosis and MRI with right mesial temporal sclerosis (MTS. After a comprehensive investigation (video-EEG intensive monitoring, interictal and ictal SPECT, and a neuropsychological evaluation including WADA test she was submitted to a right temporal lobectomy. Since then, she has been seizure-free with remission of psychosis, although with some persistence of personality traits (hiperreligiosity, viscosity which had been present before surgery. This case supports the idea that temporal lobectomy can be a safe and effective therapeutic measure for patients with MTS, refractory epilepsy and recurrent postictal epileptic psychosis or interictal epileptic psychosis with postictal exacerbation.

    Joe Yuezhou Yu

    2013-01-01

    Full Text Available Epileptic encephalopathy can be induced by inborn metabolic defects that may be rare individually but in aggregate represent a substantial clinical portion of child neurology. These may present with various epilepsy phenotypes including refractory neonatal seizures, early myoclonic encephalopathy, early infantile epileptic encephalopathy, infantile spasms, and generalized epilepsies which in particular include myoclonic seizures. There are varying degrees of treatability, but the outcome if untreated can often be catastrophic. The importance of early recognition cannot be overemphasized. This paper provides an overview of inborn metabolic errors associated with persistent brain disturbances due to highly active clinical or electrographic ictal activity. Selected diseases are organized by the defective molecule or mechanism and categorized as small molecule disorders (involving amino and organic acids, fatty acids, neurotransmitters, urea cycle, vitamers and cofactors, and mitochondria and large molecule disorders (including lysosomal storage disorders, peroxisomal disorders, glycosylation disorders, and leukodystrophies. Details including key clinical features, salient electrophysiological and neuroradiological findings, biochemical findings, and treatment options are summarized for prominent disorders in each category.

  1. Changes in physiological tremor associated with an epileptic seizure: a case report

    2011-09-01

    Full Text Available Abstract Introduction Epileptic seizures are associated with motor, sensory, somatosensory or autonomic symptoms that have all been described in varying detail over the years. Of interest in the present report is a case of normal physiological tremor, which to date has never been evaluated prior to and during an epileptic seizure. In fact, there is only anecdotal mention of pre-ictal and ictal changes in clinically noticeable tremor in the literature. Case presentation Our patient was a left-handed, 27-year-old Caucasian woman diagnosed seven years previously with partial epileptic seizures, secondarily generalized. Physiological tremor was measured simultaneously on the index finger of both hands of our patient. Electromyography as well as heart rate and respiration were also monitored. A previously performed electroencephalography examination revealed abnormal oscillations focalized to the left primary somatosensory cortex. She was also diagnosed with left frontal neuronal heterotopias. We detected subclinical changes in tremor characteristics, such as amplitude, median power frequency and power dispersion, contralateral to the localization of epileptic activity. Tremor characteristics remained relatively steady ipsilateral to the localization of the epileptic activity. Conclusions Changes in physiological tremor characteristics should be considered as another possible pre-ictal or ictal manifestation. We propose that the network associated with physiological tremor might be more sensitive to abnormal oscillations generated within the central nervous system by epileptic activity from certain structures.

    Full Text Available OBJETIVO: Comparar o aparecimento do grafoelemento de ponta positiva occipital transitória do sono em eletrencefalograma (EEG de pacientes epilépticos com e sem privação do sono, como método de ativação. MÉTODO: Foram analisados 40 EEG de 20 pacientes epilépticos com idade variando de 12 a 43 anos sendo 60% do sexo masculino, atendidos no Hospital das Clínicas da Universidade Federal de Pernambuco, no período de 1995 a 2000. Foram incluídos pacientes com epilepsia diagnosticada clinicamente e EEG sem alteração. Cada paciente foi submetido a um EEG sem privação de sono e outro após 36 horas de privação. O registro dos dois EEG foi separado por intervalo de 48 horas, obedecendo ao protocolo padrão. O efeito da privação do sono foi avaliado pelo aparecimento do grafoelemento PPOTS durante o estágio NREM do sono. RESULTADOS: No EEG sem privação do sono, a PPOTS foi identificada em 6 (30% pacientes no estágio I e em 1 (5% paciente em ambos os estágios I e II NREM. Após privação do sono, PPOTS estiveram ausentes em apenas um paciente, mas presentes em 25% casos no estágio I NREM e em 70%, nos estágios I e II NREM. CONCLUSÃO: O aumento da freqüência de PPOTS após privação do sono, parece indicar a existência da liberação de neurotransmissores excitatórios, o que pode contribuir significativamente para a investigação da excitabilidade cerebral.OBJECTIVE: To compare the presence of "sleep occipital positive transient spikes" (SOPTS in the electroencephalogram (EEG of epileptic patients without sleep deprivation (SD to those with SD, as an activation method.

  4. Assortative mixing in functional brain networks during epileptic seizures

    CERN Document Server

    Bialonski, Stephan

    2013-01-01

    We investigate assortativity of functional brain networks before, during, and after one-hundred epileptic seizures with different anatomical onset locations. We construct binary functional networks from multi-channel electroencephalographic data recorded from 60 epilepsy patients, and from time-resolved estimates of the assortativity coefficient we conclude that positive degree-degree correlations are inherent to seizure dynamics. While seizures evolve, an increasing assortativity indicates a segregation of the underlying functional network into groups of brain regions that are only sparsely interconnected, if at all. Interestingly, assortativity decreases already prior to seizure end. Together with previous observations of characteristic temporal evolutions of global statistical properties and synchronizability of epileptic brain networks, our findings may help to gain deeper insights into the complicated dynamics underlying generation, propagation, and termination of seizures.

    2007-08-01

    Rufinamide (1-[2,6-difluorobenzyl]-1H-1,2,3-triazole-4-carboxamide) is a new anti-epileptic drug with a novel triazole derivative structure. The suspected mechanism of action is limitation of sodium-dependent action potentials, thought to result in a membrane stabilizing effect. Rufinamide is extensively metabolized in the liver by non-CYP450 enzymes with an elimination half-life of 8 - 12 h. Three randomized, placebo-controlled trials have shown that rufinamide is effective against partial seizures in adults. Efficacy in the Lennox-Gastaut syndrome, a severe, disabling childhood onset epilepsy syndrome, was shown in a single, randomized, placebo-controlled trial. It has recently been approved for treatment of Lennox-Gastaut syndrome in Europe. In the US it is under regulatory review. Most common adverse effects are somnolence, fatigue, dizziness, dipolopia, nausea and ataxia. Rufinamide has shown promise as adjunctive treatment for Lennox-Gastaut syndrome and may have some role in localization related epilepsies as well.

    INTRODUCTION: Inspired by the Crisis Home programme in Madison, we have adapted and evaluated the programme at the Community Mental Health (CMH) Centre in Tønder, Denmark. MATERIAL AND METHODS: Procedures and schedules from the Crisis Home programme were applied in this open trial. Questionnaire...... data concerning satisfaction with the stay and registration data concerning the admissions and bed days two years before and two years after the first stay were obtained. RESULTS: During four years, 52 different patients had a total of 187 stays in a crisis home. Twenty (38.5%) of the patients were...... attached to the ACT team. The average duration of the stays was 4.0 days. The number of readmissions and bed days after the first stay showed a significant downward tendency for the subgroup of patients with a more severe mental disorder, but not for the whole group.

    Acne vulgaris is a common reason why adult women present to dermatologists and can be a clinical challenge to treat. It may also be an important sign of an underlying endocrine disease such as Polycystic Ovary Syndrome (PCOS). Although standard acne therapies can be successfully used to treat acne in adult female patients, hormonal treatment is a safe and effective therapeutic option that may provide an opportunity to better target acne in this population, even when other systemic therapies have failed. In this article, a practical approach to the adult female patient with acne will be reviewed to enhance the dermatologist's ability to use hormonal acne therapies and to better identify and evaluate patients with acne in the setting of a possible endocrine disorder.

    BACKGROUND: There is a paucity of data regarding hematological abnormalities in adults with Down\\'s syndrome (DS). AIMS: We aimed to characterize hematological abnormalities in adult patients with DS and determine their long-term significance. METHODS: We retrospectively studied a cohort of nine DS patients referred to the adult hematology service in our institution between May 2001 and April 2008. Data collected were: full blood count (FBC), comorbidities, investigations performed, duration of follow-up and outcome to most recent follow-up. RESULTS: Median follow-up was 26 months (9-71). Of the nine patients, two had myelodysplastic syndrome (MDS) at presentation. Of these, one progressed, with increasing marrow failure, and requiring support with transfusions and gCSF. The remaining eight patients, with a variety of hematological abnormalities including leukopenia, macrocytosis, and thrombocytopenia, had persistently abnormal FBCs. However there was no evidence of progression, and no patient has evolved to acute myeloid leukemia (AML). CONCLUSIONS: MDS is a complication of DS and may require supportive therapy. However, minor hematological abnormalities are common in adult DS patients, and may not signify underlying marrow disease.

    Full Text Available Food allergy can result in life-threatening anaphylaxis. Atopic dermatitis (AD causes intense itching and impaired quality of life. Previous studies have shown that patients with classical early-onset AD tend to develop food allergy and that 10% of adults with food allergies have concomitant AD. However, it is not known whether late-onset food allergy leads to adult-onset AD, a recently recognized disease entity. Using an initial cohort of one-million subjects, this study retrospectively followed-up 2851 patients with food allergy (age > 12 years for 14 years and compared them with 11,404 matched controls. While 2.8% (81 of the 2851 food allergy patients developed AD, only 2.0% (227 of the 11,404 controls developed AD. Multivariate regression analysis showed that food allergy patients were more likely to develop AD (adjusted hazard ratio = 2.49, p < 0.0001. Controls had a 1.99% risk of developing AD, while food allergy patients had a significantly higher risk (7.18% and 3.46% for patients with ≥3 and <3 food allergy claims, respectively of developing adult-onset AD. This is the first study to describe the chronological and dose-dependent associations between food allergy in adolescence and the development of adult-onset AD.

  12. Neonatal vitamin-responsive epileptic encephalopathies.

    The treatment of neonatal seizures generally relies on the use of one or more anticonvulsant medications along with evaluation and management of any underlying etiology. In some circumstances, neonatal seizures are refractory to therapy and result in poor outcomes, including death. Certain rare vitamin- responsive inborn errors of metabolism may present as neonatal encephalopathy with anticonvulsant-resistant seizures. Therefore, it is vital for the clinicians of caring for seizing encephalopathic newborns to consider these particular disorders early in the hospital course. Pyridoxine-dependent seizures are due to deficiency of alpha-aminoadipic semialdehyde dehydrogenase (antiquitin) which is encoded by ALDH7A1. Seizures in infants who are pyridoxine-dependent must be treated using pharmacologic doses of pyridoxine (vitamin B(6)), and life-long therapy is required. Despite medical therapy, developmental handicaps, particularly in expressive language, are common. Folinic acidresponsive seizures are treated with supplements of folinic acid (5-formyltetrahydrofolate). Recently, patients with this condition were also demonstrated to be antiquitin deficient. Pyridoxal phosphate-dependent seizures result from a deficiency of pyridox(am)ine 5'-phosphate oxidase which is encoded by PNPO. Patients with this cause of seizures respond to pyridoxal phosphate but not to pyridoxine. This review discusses our current understanding of these three neonatal vitamin-responsive epileptic encephalopathies and a diagnostic and treatment protocol is proposed.

    Full Text Available Epilepsy’s overall prevalence in Colombia is 1.13%. Its prevalence in patients aged over 65 could be around 1.5%. Objective: describe demographic and clinical characteristics of patients older than 65 years of age with epilepsy. Materials and methods: A cross-sectional descriptive study was carried out in two high complexity hospitals in Bogotá, Colombia during 2005-2008. Demographic data were compiled and patients characterized regarding the type, frequency and diagnosis of seizures (based on ILAE classification, probable etiology, having a family background of epilepsy, and current pharmacological management. Results: 211 clinical histories were reviewed and 179 of them selected. Mean patient age was 75 (65-98 and average age at onset of epilepsy was 67.5 (7-93. 84% of the seizures were classified as being focal. The most frequently occurring diagnosis was symptomatic focal epilepsy (94.4%. 74 cases (41.3% had an etiological diagnosis. The most important cause was cerebrovascular disease (61 patients. First generation anti-epileptic drugs were the most used ones (99%. 81/104 patients were found not to be free from epileptic episodes. Conclusions: Most seizures have a partial beginning, resulting from symptomatic partial epilepsy as a consequence of a vascular lesion. Pharmacological treatment must be considered following the first seizure. Treatment with second generation anti-epileptic drugs such as Lamotrigine, Gabapentin, Levetiracetam and Topiramate must be begun for minimizing secondary effects and low doses must be maintained from the start of treatment. Costs may limit the use of the above antiepileptic drugs, in such cases Phenytoin and Carbamazepine may be used with extreme caution.

    An 8-year-old girl treated at our facility for superrefractory status epilepticus was found to have a low pyridoxine level at 5 μg/L. After starting pyridoxine supplementation, improvement in the EEG for a 24-hour period was seen. We decided to look at the pyridoxine levels in adult patients admitted with status epilepticus. We reviewed the records on patients admitted to the neurological ICU for status epilepticus (SE). Eighty-one adult patients were identified with documented pyridoxine levels. For comparison purposes, we looked at pyridoxine levels in outpatients with epilepsy (n=132). Reported normal pyridoxine range is >10 ng/mL. All but six patients admitted for SE had low normal or undetectable pyridoxine levels. A selective pyridoxine deficiency was seen in 94% of patients with status epilepticus (compared to 39.4% in the outpatients) which leads us to believe that there is a relationship between status epilepticus and pyridoxine levels.

    The clinical electroencephalogram (EEG) monitoring systems based on personal computer system can not meet the requirements of portability and home usage. The epilepsy patients have to be monitored in hospital for an extended period of time, which imposes a heavy burden on hospitals. In the present study, we designed a portable 16-lead networked monitoring system based on the Android smart phone. The system uses some technologies including the active electrode, the WiFi wireless transmission, the multi-scale permutation entropy (MPE) algorithm, the back-propagation (BP) neural network algorithm, etc. Moreover, the software of Android mobile application can realize the processing and analysis of EEG data, the display of EEG waveform and the alarm of epileptic seizure. The system has been tested on the mobile phones with Android 2. 3 operating system or higher version and the results showed that this software ran accurately and steadily in the detection of epileptic seizure. In conclusion, this paper provides a portable and reliable solution for epileptic seizure monitoring in clinical and home applications.

    Full Text Available Objective. To assess body composition in adult male and female patients with thalassemia major by dual-energy X-ray absorptiometry (DXA and to compare the findings with a group of healthy age-matched controls. Methods. Our study group included sixty-two patients (27 males, mean age 36 years, and 35 females, mean age 36.4 years and fifteen age-matched healthy controls. All patients had an established diagnosis of thalassemia major and followed a regular blood transfusion scheme since childhood and chelation treatment. Fat, lean, and bone mineral density (BMD were assessed with dual-energy X-ray absorptiometry. Ferritin levels and body mass index of all patients and controls were also recorded. Student t-test and Wilcoxon test were performed and statistical significance was set at p<0.05. Results. BMD and whole body lean mass are lower in both male and female adult patients compared with controls (p<0.01 in both groups, whereas whole body fat mass was found to have no statistically significant difference compared to controls. Regional trunk fat around the abdomen was found to be lower in male patients compared to controls (p=0.02. Conclusion. Severe bone loss and diminished lean mass are expected in adult male and female patients with thalassemia major. Fat changes seem to affect mainly male patients.

    Full Text Available Background Epilepsy is a restrained neurological disorder, with a constant neuronal damage, ranging from severe, life-threatening and disabling situations. It leads to oxidative brain damages through DNA fragmentation. Pentylenetetrazole (PTZ is a convulsant used to produce experimental epileptic animals. Investigation proved; antioxidant enriched Spinacea oleracea (SO or spinach, a commonly available herb, has a modulatory role on the damaging effects of free radicals. Methods The study was conducted with twenty-four adult male Holtzman strain albino rats (200-250gm. These rats were divided into groups of Control, SO treated control, PTZ induced experimental epileptic group and SO pretreated PTZ induced experimental epileptic group. The epileptic model was prepared by intraperitoneal administration of PTZ at a dose of 40 mg/kg body weight. Aqueous leaf extract of SO was orally given at a dose of 400 mg /kg body weight, for fourteen consecutive days. After the behavioral study serum and brain tissue samples were collected for the estimation of nitric oxide (NO, DNA fragmentation and antioxidants level. Results Pretreatment with SO leaf extract showed significant decrease in the seizure score, ictal phase, serum NO level, LPO levels and rate of DNA fragmentation. The interictal phase, SOD, CAT, GSH activity of different parts of the brain were significantly increased in SO pretreated PTZ induced group. Conclusion SO is found to play a vital role to provide protection against the oxidative damage of epileptic brain by amending the levels of antioxidants and serum NO level.

    Full Text Available Background: the occurrence of psychogenic non-epileptic seizures (PNES is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is to present the effects of individual psychoanalytical treatment in patients with PNES, assessing its impact in the evolution of the clinical picture and its association with sex, time of disease, social, psychological and professional harm, as well as going through with treatment. Methods: The case base was composed of 37 patients with PNES. The diagnosis was reached with video-EEG monitoring. Psychoanalytical treatment was carried out through 12 months of weekly sessions timed for around 50-minutes each, in a total of 48 individual sessions. Results: This study found a high rate of success in the treatment of PNES patients. 29.7% (n=11 of patients had cessation or cure of symptoms and 51.4% (n=19 had a decrease in the number of episodes. There is an association between cessation or decrease in the number of episodes and sex (p<0.01, religion (p<0.01 and concluding treatment (p<0.01. Conclusion: Individual psychoanalytical treatment applied to patients with PNES is considered effective and can be an essential form of assistance for the reduction or cessation of episodes.

    The underlying dynamics for the electroencephalographic (EEG) recordings from humans but especially epilepsy patients are usually not completely known. However, the ictal activity is claimed to be characterized by synchronous oscillations in the brain voltages in the literature. These time dependent interdependencies (synchronization, coupling) between the EEG voltages from epileptogenic and non epileptogenic brain sites of nineteen focal epileptic patients are investigated in this work. It is found that strong synchronizationdesynchronization events occur in alternation during most of the investigated seizures. Thus, these seizures are detected with considerable sensitivity (71 of the 79 seizures).

    Classical galactosemia is an autosomal recessive inborn error of metabolism leading to toxic accumulation of galactose and derived metabolites. It presents with acute systemic complications in the newborn. Galactose restriction resolves these symptoms, but long-term complications, such as premature ovarian failure and neurological problems including motor dysfunction, may occur despite adequate treatment. The objective of the current study was to determine the frequency and phenotype of motor problems in adult patients with classical galactosemia. In this cross-sectional study, adult patients with a biochemically confirmed diagnosis of galactosemia attending our clinic were assessed with an interview and neurological examination and their notes retrospectively reviewed. Patients were classified according to the presence/absence of motor dysfunction on examination. Patients with motor dysfunction were further categorized according to the presence/absence of reported motor symptoms. Forty-seven patients were included. Thirty-one patients showed evidence of motor dysfunction including: tremor (23 patients), dystonia (23 patients), cerebellar signs (6 patients), and pyramidal signs (4 patients). Tremor and dystonia were often combined (16 patients). Thirteen patients reported motor symptoms, with 8 describing progressive worsening. Symptomatic treatment was effective in 4 of 5 patients. Nonmotor neurological features (cognitive, psychiatric, and speech disorders) and premature ovarian failure were more frequent in patients with motor dysfunction. Motor dysfunction is a common complication of classical galactosemia, with tremor and dystonia the most frequent findings. Up to one third of patients report motor symptoms and may benefit from appropriate treatment. Progressive worsening is not uncommon and may suggest ongoing brain damage in a subset of patients.

    Full Text Available Anand K Sarma,1 Nabil Khandker,1 Lisa Kurczewski,2 Gretchen M Brophy2 1Department of Neurology, 2Departments of Pharmacotherapy & Outcomes Science and Neurosurgery, Virginia Commonwealth University, Richmond, VA, USA Abstract: Epilepsy is one of the most common neurologic illnesses. This condition afflicts 2.9 million adults and children in the US, leading to an economic impact amounting to $15.5 billion. Despite the significant burden epilepsy places on the population, it is not very well understood. As this understanding continues to evolve, it is important for clinicians to stay up to date with the latest advances to provide the best care for patients. In the last 20 years, the US Food and Drug Administration has approved 15 new antiepileptic drugs (AEDs, with many more currently in development. Other advances have been achieved in terms of diagnostic modalities like electroencephalography technology, treatment devices like vagal nerve and deep-brain stimulators, novel alternate routes of drug administration, and improvement in surgical techniques. Specific patient populations, such as the pregnant, elderly, those with HIV/AIDS, and those with psychiatric illness, present their own unique challenges, with AED side effects, drug interactions, and medical–psychiatric comorbidities adding to the conundrum. The purpose of this article is to review the latest literature guiding the management of acute epileptic seizures, focusing on the current challenges across different practice settings, and it discusses studies in various patient populations, including the pregnant, geriatric, those with HIV/AIDS, comatose, psychiatric, and “pseudoseizure” patients, and offers possible evidence-based solutions or the expert opinion of the authors. Also included is information on newer AEDs, routes of administration, and significant AED-related drug-interaction tables. This review has tried to address only some of these issues that any practitioner who

  5. Infantile epileptic syndromes and metabolic etiologies.

    Science.gov (United States)

    Vigevano, Federico; Bartuli, Andrea

    2002-12-01

    Inherited metabolic disorders can cause onset of epilepsy in the first year of life. Epilepsy rarely dominates the clinical presentation, which is more frequently associated with other neurologic symptoms, such as mental retardation, hypotonia and/or dystonia, or vigilance disturbances. The pathogenesis of seizures is multifaceted; inherited metabolic disorder can affect the balance between excitatory and inhibitory chemical mediators, eliminate an energetic substrate at the cerebral level, cause in utero brain malformation, or provoke acute brain lesions. Some clinical disorders that strongly suggest particular metabolic etiologies can be identified. For example, specific clinical signs and findings on electroencephalogram (EEG) are characteristic of pyridoxine-dependent seizures, and inherited metabolic disorders associated with early myoclonic encephalopathy are well defined. In most cases, however, epilepsy secondary to inherited metabolic disorders presents with polymorphic clinical and EEG features that are difficult to classify into precise epileptic syndromes. Common characteristics of these seizures include onset in the first months of life; usually partial, multifocal; simple partial motor semiology; successive appearance of tonic seizures, spasms, and massive myoclonus; and resistance to antiepilepsy drugs. Inherited metabolic disorders must be considered in patients presenting with epilepsy and progressive neurologic worsening.

    2011-08-01

    Full Text Available Epilepsy is a complex disease, characterized by the repeated occurrence of bursts of electrical activity (seizures in specific brain areas. The behavioral outcome of seizure events strongly depends on the brain regions that are affected by overactivity. Here we review the intracellular signaling pathways involved in the generation of seizures in epileptogenic areas. Pathways activated by modulatory neurotransmitters (dopamine, norepinephrine and serotonin, involving the activation of extracellular-regulated kinases (ERKs and the induction of immediate early genes (IEGs will be first discussed in relation to the occurrence of acute seizure events. Activation of immediate early genes has been proposed to lead to long-term molecular and behavioral responses induced by acute seizures. We also review deleterious consequences of seizure activity, focusing on the contribution of apoptosis-associated signaling pathways to the progression of the disease. A deep understanding of signaling pathways involved in both acute and long-term responses to seizures continues to be crucial to unravel the origins of epileptic behaviors and ultimately identify novel therapeutic targets for the cure of epilepsy.

    1988-04-01

    A 15 years-old girl with no previous history of epilepsy or neurological disease presented three types of epileptic symptoms the same day: 1) clusters of rhythmic myoclonus of the left hemiface; 2) episodes of painful paresthesias of the left arm followed by secondary generalised seizures; 3) episodes of elementary visual hallucinations of the right hemifield. She had several seizures each hour and some were recorded. There were no EEG abnormalities during the facial myoclonus but rapid rhythms were seen during the sensory and visual partial seizures on the right parietal and left occipital lobes. There was no fever and no drowsiness. The CSF tap showed pleocytosis. Serological studies indicated recent mumps. The drugs were initially inefficient. The seizures disappeared after a month. The drugs were stopped after three months and the seizures had not relapsed after a one year's follow-up. Though there were no other sign of encephalitis, we believe that episode of multifocal seizures was due to mumps encephalitis.

  11. Therapeutic approach to epileptic encephalopathies.

    2013-11-01

    Epileptic encephalopathies (EEs) are electroclinical entities with a peculiar course of disease; seizures and electroencephalographic (EEG) epileptiform abnormalities, ictal and interictal, contribute to progressive disturbance of cerebral functions. Frequently EEs are drug resistant, and consequences may be catastrophic. The main goal of treatment is to stop the peculiar course of epilepsy, operating on three parameters: seizure control, reduction of EEG abnormalities, and developmental outcome. For a correct therapeutic approach it is mandatory to have an as accurate as possible syndromic and etiologic diagnosis. Given the poor efficacy of conventional antiepileptic drugs (AEDs), the use of specific drugs for EEs, such as adrenocorticotropic hormone (ACTH) and corticosteroids or stiripentol is suggested. In some cases the choice of treatment is strictly related to the etiology: vigabatrin in tuberous sclerosis, ketogenic diet in glucose transporter type 1 (GLUT-1) deficiency, and pyridoxine in pyridoxine deficiency. Some AEDs combinations, such as sodium valproate with lamotrigine, have also provided interesting results, for example, in Lennox-Gastaut syndrome, although controlled studies are lacking. Finally, early surgery can be an option in children with focal structural abnormalities responsible for EEs preferably before irreversible damage on developmental outcome. Multispecialist support is recommended in EE. Management should be global from the onset, integrating not only seizure control but also all issues related to comorbidities, particularly neuropsychological and psychiatric.

  12. Patient-specific FDG dosimetry for adult males, adult females, and very low birth weight infants

    Science.gov (United States)

    Niven, Erin

    Fluorodeoxyglucose is the most commonly used radiopharmaceutical in Positron Emission Tomography, with applications in neurology, cardiology, and oncology. Despite its routine use worldwide, the radiation absorbed dose estimates from FDG have been based primarily on data obtained from two dogs studied in 1977 and 11 adults (most likely males) studied in 1982. In addition, the dose estimates calculated for FDG have been centered on the adult male, with little or no mention of variations in the dose estimates due to sex, age, height, weight, nationality, diet, or pathological condition. Through an extensive investigation into the Medical Internal Radiation Dose schema for calculating absorbed doses, I have developed a simple patient-specific equation; this equation incorporates the parameters necessary for alterations to the mathematical values of the human model to produce an estimate more representative of the individual under consideration. I have used this method to determine the range of absorbed doses to FDG from the collection of a large quantity of biological data obtained in adult males, adult females, and very low birth weight infants. Therefore, a more accurate quantification of the dose to humans from FDG has been completed. My results show that per unit administered activity, the absorbed dose from FDG is higher for infants compared to adults, and the dose for adult women is higher than for adult men. Given an injected activity of approximately 3.7 MBq kg-1, the doses for adult men, adult women, and full-term newborns would be on the order of 5.5, 7.1, and 2.8 mSv, respectively. These absorbed doses are comparable to the doses received from other nuclear medicine procedures.

    Conclusion: Cardiac troponin I is a perfect tool for early detection of cases with myocardial dysfunction in epileptic patients – cardiac troponin I is significantly increased in children with epilepsy especially the complicated epilepsy. Cardiac injury in epileptic children is more common in patients with early onset epilepsy, positive prenatal problem, idiopathic epilepsy, abnormal imaging and EEG – elevated TnI levels may be of value in assessing the severity and eventual outcome and mortality risk of the disease in children with epilepsy.

  15. Canine and feline epileptic seizures and the lunar cycle: 2,507 seizures (2000-2008).

    2011-01-01

    Epileptic seizures in 211 canine and feline patients diagnosed with idiopathic epilepsy were evaluated for temporal significance in relation to the lunar cycle. Seizure counts were compared among each of the eight individual lunar phases, among each of eight exact lunar phase dates, and by percent of lunar illumination using generalized estimating equations. No statistical significance was found in any of these comparisons excluding a relationship between the onset of epileptic seizures and the phases of the moon. Alteration in anticonvulsant treatment or monitoring of canine and feline patients with idiopathic epilepsy at large was not warranted based on the lunar cycle.

    Vitamin B6 is closely associated with functions of the nervous, immune, and endocrine systems. Its deficiency may result in neurological disorders including convulsions and epileptic encephalopathy. Until today, this has only been reported in infants, children, and critically ill adult patients. We report a case of a 36year-old man with chronic alcoholism who presented with seizures after gastrointestinal disturbance. His seizures persisted even after treatment with antiepileptic drugs, but e...

    Any abnormal hypersynchronus activity of neurons can be characterized as an epileptic seizure (ES). A broad class of non-epileptic seizures is comprised of Psychogenic non-epileptic seizures (PNES). PNES are paroxysmal events, which mimics epileptic seizures and pose a diagnostic challenge with epileptic seizures due to their clinical similarities. The diagnosis of PNES is done using video-electroencephalography (VEM) monitoring. VEM being a resource intensive process calls for alternative methods for detection of PNES. There is now an emerging interest in the use of accelerometer based devices for the detection of seizures. In this work, we present an algorithm based on Gaussian mixture model (GMM's) for the identification of PNES, ES and normal movements using a wrist-worn accelerometer device. Features in time, frequency and wavelet domain are extracted from the norm of accelerometry signal. All events are then classified into three classes i.e normal, PNES and ES using a parametric estimate of the multivariate normal probability density function. An algorithm based on GMM's allows us to accurately model the non-epileptic and epileptic movements, thus enhancing the overall predictive accuracy of the system. The new algorithm was tested on data collected from 16 patients and showed an overall detection accuracy of 91% with 25 false alarms.

    In the nineteenth century, epilepsy became subject of experimental research. Lombroso established a relationship between epilepsy and criminality believing in the existence of epileptoid traits and atavism. He tried to demonstrate the common origin of epilepsy, criminality, and genius; factors deteriorating the CNS would act upon centers, which control behavior and ethics. This impairment would cause a lack of control on the lower nervous centers, reducing restraints of instincts and criminal behavior. He described developmental frontal cortex lesions in epileptic patients (today Taylor's dysplasia) and these observations supported the erroneous conviction of a relationship between criminality and epilepsy. Neurological, behavioral, and criminological sciences analyzed Lombroso's doctrine, whereas it was controversial that epileptic patients should be prone to violent actions and aggressive behavior. Today, there is an international panel of experts on epilepsy, which suggests five relevant criteria to determine if a crime committed with aggressiveness could result from epileptic seizures.

    The biggest challenge restorative dentists face in rehabilitating patients with amelogenesis imperfecta (AI) is trying to restore aesthetics, function and occlusal stability while keeping the treatment as conservative as possible. The goals of treatment should be to prolong the life of the patient's own teeth and avoid or delay the need for extractions and subsequent replacement with conventional fixed, removable or implant retained prostheses. In order to achieve these goals a stepwise approach to treatment planning is required starting with the most conservative but aesthetically acceptable treatment. This article discusses the management of AI and presents the various treatment options available for restoring the adult patient who presents to the dentist with AI.

  2. Optimal serum phenylalanine for adult patients with phenylketonuria.

    High serum phenylalanine in adult patients with phenylketonuria (PKU) causes neuropsychological and psychosocial problems that can be resolved by phenylalanine-restricted diet. Therefore, PKU patients must continue to adhere to phenylalanine-restricted diet for life, although the optimal serum phenylalanine level in later life has yet to be established. The purpose of this review was to establish the optimal serum phenylalanine level in later life of PKU patients. We evaluated oxidative stress status, nitric oxide metabolism, cholesterol-derived oxysterols, vitamin D and bone status, and magnetic resonance imaging (MRI) in adult PKU patients according to serum phenylalanine level. Oxidative stress increased markedly at serum phenylalanine of 700-800 μmol/L. Serum phenylalanine higher than 700-850 μmol/L correlated with the disturbance of nitric oxide regulatory system. Adult PKU patients had poor vitamin D status and exhibited predominance of bone resorption over bone formation. In the brain, the levels of 24S-hydroxycholesterol, a marker of brain cholesterol elimination, were low at serum phenylalanine levels exceeding 650 μmol/L. MRI studies showed high signal intensity in deep white matter on T2-weighted and FLAIR images of PKU patients with serum phenylalanine greater than 500 μmol/L, with decreased apparent diffusion coefficients. Changes in most parameters covering the entire body organs in adult PKU were almost acceptable below 700-800 μmol/L of phenylalanine level. However, the optimal serum phenylalanine level should be 500 μmol/L or less in later life for the brain to be safe.

    Pancreatic exocrine insufficiency is usually present in patients with pancreatic diseases. Surprisingly, recent studies indicated that patients with critical illness often suffer from pancreatic injury due to non-specific reasons other than pancreatic diseases, and pancreatic exocrine insufficiency is also commonly observed in critically ill adult patients without preexisting pancreatic diseases. It is well known that malnutrition is the main clinical consequence of pancreatic exocrine insufficiency, thus, the high incidence of pancreatic exocrine insufficiency is most likely to be an important contributor of malnutrition which is a frequent problem associated with detrimental clinical outcomes in critically ill patients admitted into intensive care unit. In order to prevent pancreatic exocrine insufficiency due to primary pancreatic diseases, pancreatic enzyme replacement therapy is indispensable to treat indigestion, malabsorption and nutritional deficiency. Similarly, pancreatic enzyme supplementation has the potential to be an adjuvant therapy in critically ill patients with enteral nutrition therapy, which may be helpful to improve the nutritional status and the prognosis of critically ill patients by reducing the occurrence of malnutrition. Here, we reviewed the diagnostic methods of pancreatic exocrine function, the epidemiology and risk factors of pancreatic exocrine insufficiency, and potential treatment strategies for pancreatic exocrine insufficiency in critically ill adult patients.

    The value of nutrition therapy for the adult hospitalized patient is derived from the outcome benefits achieved by the delivery of early enteral feeding. Nutritional assessment should identify those patients at high nutritional risk, determined by both disease severity and nutritional status. For such patients if they are unable to maintain volitional intake, enteral access should be attained and enteral nutrition (EN) initiated within 24-48 h of admission. Orogastric or nasogastric feeding is most appropriate when starting EN, switching to post-pyloric or deep jejunal feeding only in those patients who are intolerant of gastric feeds or at high risk for aspiration. Percutaneous access should be used for those patients anticipated to require EN for >4 weeks. Patients receiving EN should be monitored for risk of aspiration, tolerance, and adequacy of feeding (determined by percent of goal calories and protein delivered). Intentional permissive underfeeding (and even trophic feeding) is appropriate temporarily for certain subsets of hospitalized patients. Although a standard polymeric formula should be used routinely in most patients, an immune-modulating formula (with arginine and fish oil) should be reserved for patients who have had major surgery in a surgical ICU setting. Adequacy of nutrition therapy is enhanced by establishing nurse-driven enteral feeding protocols, increasing delivery by volume-based or top-down feeding strategies, minimizing interruptions, and eliminating the practice of gastric residual volumes. Parenteral nutrition should be used in patients at high nutritional risk when EN is not feasible or after the first week of hospitalization if EN is not sufficient. Because of their knowledge base and skill set, the gastroenterologist endoscopist is an asset to the Nutrition Support Team and should participate in providing optimal nutrition therapy to the hospitalized adult patient.

  5. Aspartic acid aminotransferase activity is increased in actively spiking compared with non-spiking human epileptic cortex.

    Increased concentration of the excitatory neurotransmitter aspartic acid in actively spiking human epileptic cerebral cortex was recently described. In order to further characterise changes in the aspartergic system in epileptic brain, the behaviour of aspartic acid aminotransferase (AAT), a key enzyme involved in aspartic acid metabolism has now been examined. Electrocorticography performed during surgery was employed to identify cortical epileptic spike foci in 16 patients undergoing temporal lobectomy for intractable seizures. Patients with spontaneously spiking lateral temporal cortex (n = 8) were compared with a non-spiking control group (n = 8) of patients in whom the epileptic lesions were confined to the hippocampus sparing the temporal convexity. Mean activity of AAT in spiking cortex was significantly elevated by 16-18%, with aspartic acid concentration increased by 28%. Possible explanations for the enhanced AAT activity include increased proliferation of cortical AAT-containing astrocytes at the spiking focus and/or a generalised increase in neuronal or extraneuronal metabolism consequent to the ongoing epileptic discharge. It is suggested that the data provide additional support for a disturbance of central excitatory aspartic acid mechanisms in human epileptic brain. PMID:2898010

  6. Transfer function between EEG and BOLD signals of epileptic activity

    2013-01-01

    Full Text Available Simultaneous EEG-fMRI recordings have seen growing application in the evaluation of epilepsy, namely in the characterization of brain networks related to epileptic activity. In EEG-correlated fMRI studies, epileptic events are usually described as boxcar signals based on the timing information retrieved from the EEG, and subsequently convolved with a heamodynamic response function to model the associated BOLD changes. Although more flexible approaches may allow a higher degree of complexity for the haemodynamics, the issue of how to model these dynamics based on the EEG remains an open question. In this work, a new methodology for the integration of simultaneous EEG-fMRI data in epilepsy is proposed, which incorporates a transfer function from the EEG to the BOLD signal. Independent component analysis (ICA of the EEG is performed, and a number of metrics expressing different models of the EEG-BOLD transfer function are extracted from the resulting time courses. These metrics are then used to predict the fMRI data and to identify brain areas associated with the EEG epileptic activity. The methodology was tested on both ictal and interictal EEG-fMRI recordings from one patient with a hypothalamic hamartoma. When compared to the conventional analysis approach, plausible, consistent and more significant activations were obtained. Importantly, frequency-weighted EEG metrics yielded superior results than those weighted solely on the EEG power, which comes in agreement with previous literature. Reproducibility, specificity and sensitivity should be addressed in an extended group of patients in order to further validate the proposed methodology and generalize the presented proof of concept.

The epileptic percentages in different sorts of work, in March 1996 was compared with the one after three-year follow-up period in March 1999. There were no statistical significant changes among the same sorts of work in this period. However, there were intense migrations in relation to different sorts of work. Paid work showed migration to unemployment and retirement. This research shows the significant migration of epileptic patient either to some kind of a less qualified work or to some social security dependence as well as to early retirement.

    Fall prevention is a major area of concern in inpatient settings. This article reports on the feasibility of implementing a daily exercise program that features line dancing to promote stability, balance, and flexibility in adult psychiatric patients and describes the impact of that program. Six hundred sixty-five patient charts drawn from before and after the practice change were reviewed. The fall rate after the introduction of line dancing was 2.8% compared with 3.2% before implementation. In a setting that treats both men and women of many ages and with varying levels of mobility, line dancing offers a viable approach to exercise in a secure setting.

    A method is proposed to process ECD brain SPECT images representing epileptic hot spots inside the brain. For validation 35 ictal —interictal patient image data were processed. The images were registered by a normalized mutual information method, then the separation of the suspicious and normal brain areas were performed by two threshold-based segmentations. Normalization between the images was performed by local normal brain mean values. Based on the validation made by two medical physicians, minimal human intervention in the segmentation parameters was necessary to detect all epileptic spots and minimize the number of false spots inside the brain.

    In recent years, the healthcare system has grown increasingly aware of the need to develop and adopt new models and intervention methods aimed at improving patients' quality of life. As part of this perception, medical clowns have been integrated into hospitals, primarily in work with children. Recently, there have been attempts to integrate clowns into work with adult patients in emergency rooms, but this intervention method has not yet been systematically implemented and studied. This article describes and examines the definition of the medical clown's role as an intervention strategy with adult outpatients suffering from chronic and life-threatening illnesses. The study is qualitative and based on a content analysis of the documentation of the work of two medical clowns over two years. The dominant theme arising from this analysis involves the definition of the clown's role within the medical space of the hospital and includes perspectives on his integration into the hospital's multidisciplinary medical staff and his impact on the staff and on patients and their families. The findings indicate that, from the clowns' point of view, integrated medical clowns as part of the medical team, would contribute to the functioning of both patients and staff. This is in accord with additional studies conducted recently in medical centers around the world. Since this is a pioneering study, there is room to further probe and research the medical clown's contribution to assisting and improving patients' and staff's quality of life and to develop ways of increasing his integration and professionalism.

    Full Text Available INTRODUCTION: The length of time that it takes an orthodontist to treat adult patients varies widely. OBJECTIVE: The aim of this study was to investigate how different variables influence treatment time. METHODS: Seventy clinical case reports of successfully treated adult patients were examined. The patients were selected from 4,723 records held by three experienced orthodontists. The influence exerted by the following variables on treatment time was assessed: age, sex, facial pattern, severity of malocclusion (measured by the PAR index, sagittal relationship of canines, type of brackets (ceramic or metal, tooth extractions, missed appointments and orthodontic appliance issues/breakages, the latter being the dependent variable. Assessment was performed by multiple linear regression analysis, followed by the stepwise method with P < 0.05. RESULTS: The number of times a patient missed their appointment (no-show (R² = 14.4%, p < 0.0001 and the number of appliance issues/breakages (R² = 29.71%, p = 0.0037 significantly affected variability in treatment time, and these two variables together can predict 43.75% (R² total of the overall variability in treatment time. Other factors, such as canine relationship at the beginning of treatment, bracket type (metal or ceramic, tooth extractions, age at start of treatment, severity of the initial malocclusion, sex and facial pattern had no significant bearing on treatment time. CONCLUSIONS: The duration of orthodontic treatment in adults, when performed by experienced orthodontists, is mainly influenced by factors related to patient compliance. However, several factors which were not included in this study may contribute to variability in orthodontic treatment time.

    Full Text Available Abstract Background Paramedics are often a first point of contact for people experiencing pain in the community. Wherever possible the patient's self report of pain should be sought to guide the assessment and management of this complaint. Communication difficulty or disability such as cognitive impairment associated with dementia may limit the patient's ability to report their pain experience, and this has the potential to affect the quality of care. The primary objective of this study was to systematically locate evidence relating to the use of pain assessment tools that have been validated for use with cognitively impaired adults and to identify those that have been recommended for use by paramedics. Methods A systematic search of health databases for evidence relating to the use of pain assessment tools that have been validated for use with cognitively impaired adults was undertaken using specific search criteria. An extended search included position statements and clinical practice guidelines developed by health agencies to identify evidence-based recommendations regarding pain assessment in older adults. Results Two systematic reviews met study inclusion criteria. Weaknesses in tools evaluated by these studies limited their application in assessing pain in the population of interest. Only one tool was designed to assess pain in acute care settings. No tools were located that are designed for paramedic use. Conclusion The reviews of pain assessment tools found that the majority were developed to assess chronic pain in aged care, hospital or hospice settings. An analysis of the characteristics of these pain assessment tools identified attributes that may limit their use in paramedic practice. One tool - the Abbey Pain Scale - may have application in paramedic assessment of pain, but clinical evaluation is required to validate this tool in the paramedic practice setting. Further research is recommended to evaluate the Abbey Pain Scale and to

    OBJECTIVE: The health locus of control is the subjective perception of control over one's health. It has been studied for years as one of several factors that determine patient health-related behaviors. The aim of this study was to investigate how the epileptic aura is associated with the health...... locus of control, anxiety, and depression. METHODS: Patients were included retrospectively, based on patient records from the epilepsy monitoring unit of the Rigshospitalet University Hospital. Participants were asked about the presence and nature of auras in a semistructured interview...... of others (e.g., doctors and parents). The Hospital Anxiety and Depression Scale was used to evaluate levels of anxiety and depression. RESULTS: Forty-nine patients, with mean age of 38years, participated in the study. Of these, 67% reported experiencing one or more auras; i.e., subjective warning signs...

    Preditive clinical factors for epileptic seizures after ischemic stroke. Clinical features of 35 patients with ischemic stroke who developed epilepsy (Group 1) were compared with those of 35 patients with ischemic stroke without epilepsy (Group 2). The age of the patients did not differ between the groups. There were more men than women and more white than other races in both groups. Diabetes melitus, hypertension, transient ischemic attack, previous stroke, migraine, Chagas disease, cerebral embolism of cardiac origin and use of oral contraceptive did not differ between the groups. Smokers and alcohol users were more frequent in Group 1 (p < 0.05). Most patients of Group 1 presented with hemiparesis; none presented cerebellar or brainstem involvement. Perhaps strokes in smokers have some different aspects, that let them more epileptogenic than in non smokers.

    Epileptic patients show a large range of psychopathologic manifestations, both from a qualitative point of view (even with an exact reference to the nature and the site of lesion) and from a quantitative point of view (from the so-called characterial attitude to the psychotic developments). Perhaps all these alterations of psychiatric interest have a common denominator because, after all, they arise from the sum of two essential moments: the experience of the critical event on the one hand, and the interactive network between the patient and those who are present to his critical manifestations on the other. In particular this complex relational psychopathology needs several therapeutic interventions which are to be complementary and concordant so that they may give satisfactory results of psychosocial reinsertion. We think that the model of intervention to be preferred for its effectiveness is that drawn from group-psychotherapy tecniques: the model in which "psychoanalysis meets sociology (Foulkes) seems to be particularly specific to this problem because it concerns the microsocial and investigates (and, by means of the conduction, it resolves) distorted ways of communication and conflictual dynamic interactions. We followed some epileptics in the group-community of the neurological department of a general hospital (of course with other mental, not epileptic, patients). These preliminary studies lead us to point out the theoretical reasons and the practical justifications of such possible management of the psychological manifestations of epileptic patients.

  5. Hyperspherical Manifold for EEG Signals of Epileptic Seizures

    2012-01-01

    Full Text Available The mathematical modelling of EEG signals of epileptic seizures presents a challenge as seizure data is erratic, often with no visible trend. Limitations in existing models indicate a need for a generalized model that can be used to analyze seizures without the need for apriori information, whilst minimizing the loss of signal data due to smoothing. This paper utilizes measure theory to design a discrete probability measure that reformats EEG data without altering its geometric structure. An analysis of EEG data from three patients experiencing epileptic seizures is made using the developed measure, resulting in successful identification of increased potential difference in portions of the brain that correspond to physical symptoms demonstrated by the patients. A mapping then is devised to transport the measure data onto the surface of a high-dimensional manifold, enabling the analysis of seizures using directional statistics and manifold theory. The subset of seizure signals on the manifold is shown to be a topological space, verifying Ahmad's approach to use topological modelling.

    evaluate NC as aetiology of epilepsy in the west of Santa Catarina. This state belong to southern Brazil and it has a very developed economy. However, due the widespread swine farming in the west district, many of them without any sanitary control, the national health authorities have considered all this area at risk to NC. The study was carried out in Chapecó, the main town in that region, where CT Scan service was started in 1995. All patients put on hospital care due epileptic seizures in 1995-96 were considered. Febrile convulsions were excluded of the sample. We found a very expressive prevalence rate of NC among patients suffering from epilepsy. Roughly 24% of these patients, showed unequivocal tomography evidences for the diagnosis of NC. Our data suggest cysticercosis as a real endemic trouble in the area and, overdosis of information in proper language, diffuse to the whole population, seems to be the only remedy to fight against it. Moreover, we should pay special attention to everyone related to swine farming, does not matter how this activity has been classificated.

    Full Text Available Purpose: Trauma is one of the most common reason of admissions to emergency departments. In this study, it was aimed to determine the demographic characteristics, etiology, morbidity and mortality rates and prognosis of adult trauma patients admitted to our emergency department (ED. Materials and Methods: Patients over the age of 18 years, who admitted to ED between 01 March 2011 and 31 August 2011 were included in this retrospective study. Patient examination cards, hospitalization files and records entered with ICD 10 codes to hospital automation system were analyzed. Patients with inaccessible data were excluded from the study. Results: During the study period, total number of 110495 patients admitted to ED, and 13585 (12,29% of them admitted with trauma. Simple extremity injuries (38,28% and falls (31,7% were most common etiological factors. Glasgow coma scales of 99,71% of the patients were between 13 and 15. Of the patients with trauma, 9,6% had a Computed Tomography (CT scan, and 84,5% of CT scans were evaluated as normal, and cranial CT was the most requested one. Only 6% of the patients were hospitalized, and 0,9% of the trauma patients died. Falls from height in females and traffic accidents in males were the leading causes of death. Conclusion: Most of the patients with simple traumas admitted to ED can be discharged from the hospital with a complete history and careful examination. The rate of unnecessary medical tests, loss of time and waste money should be reduced, and the time and labor allocated to severe patients can be increased by this way.

    Synaptic vesicle protein 2A (SV2A) involvement has been reported in the animal models of epilepsy and in human intractable epilepsy. The difference between pharmacosensitive epilepsy and pharmacoresistant epilepsy remains poorly understood. The present study aimed to observe the hippocampus SV2A protein expression in amygdale-kindling pharmacoresistant epileptic rats. The pharmacosensitive epileptic rats served as control. Amygdaloid-kindling model of epilepsy was established in 100 healthy adult male Sprague-Dawley rats. The kindled rat model of epilepsy was used to select pharmacoresistance by testing their seizure response to phenytoin and phenobarbital. The selected pharmacoresistant rats were assigned to a pharmacoresistant epileptic group (PRE group). Another 12 pharmacosensitive epileptic rats (PSE group) served as control. Immunohistochemistry, real-time PCR and Western blotting were used to determine SV2A expression in the hippocampus tissue samples from both the PRE and the PSE rats. Immunohistochemistry staining showed that SV2A was mainly accumulated in the cytoplasm of the neurons, as well as along their dendrites throughout all subfields of the hippocampus. Immunoreactive staining level of SV2A-positive cells was 0.483 ± 0.304 in the PRE group and 0.866 ± 0.090 in the PSE group (P kindling rats.

    Full Text Available Fontan and Baudet described in 1971 the separation of the pulmonary and systemic circulations resulting in univentricular physiology. The evolution of the Fontan procedure, most notably the substitution of right atrial-to-pulmonary artery anastomosis with cavopulmonary connections, resulted in significantly improved late outcomes. Many patients survive well into adulthood and are able to lead productive lives. While ideally under medical care at specialized centers for adult congenital cardiac pathology, these patients may present to the outside hospitals for emergency surgery, electrophysiologic interventions, and pregnancy. This presentation presents a “train of thought,” linking the TEE images to the perioperative physiologic considerations faced by an anesthesiologist caring for a patient with Fontan circulation in the perioperative settings. Relevant effects of mechanical ventilation on pulmonary vascular resistance, pulmonary blood flow and cardiac preload, presence of coagulopathy and thromboembolic potential, danger of abrupt changes of systemic vascular resistance and systemic venous return are discussed.

    Epileptic seizures are generated by abnormal activity of neurons. The prediction of epileptic seizures is an important issue in the field of neurology, since it may improve the quality of life of patients suffering from drug resistant epilepsy. In this study a new similarity index based on symbolic dynamic techniques which can be used for extracting behavior of chaotic time series is presented. Using Freiburg EEG dataset, it is found that the method is able to detect the behavioral changes of the neural activity prior to epileptic seizures, so it can be used for prediction of epileptic seizure. A sensitivity of 63.75% with 0.33 false positive rate (FPR) in all 21 patients and sensitivity of 96.66% with 0.33 FPR in eight patients were achieved using the proposed method. Moreover, the method was evaluated by applying on Logistic and Tent map with different parameters to demonstrate its robustness and ability in determining similarity between two time series with the same chaotic characterization.

    Childhood absence epilepsy (CAE) and benign childhood epilepsy with centrotemporal spikes (BCECTS), or benign rolandic epilepsy (BRE), are the most common forms of childhood epilepsy. CAE and BCECTS are well-known and clearly defined syndromes; although they are strongly dissimilar in terms of their pathophysiology, these functional epileptic disturbances share many features such as similar age at onset, overall good prognosis, and inheritance factors. Few reports are available on the concomitance of CAE and BCECTS in the same patients or the later occurrence of generalized epilepsy in patients with a history of partial epilepsy. In most cases described in the literature, absence seizures always started after the onset of benign focal epilepsy but the contrary has never occurred yet. We describe two patients affected by idiopathic generalized epileptic syndrome with typical absences, who experienced BCECTS after remission of seizures and normalization of EEG recordings. While the coexistence of different seizure types within an epileptic syndrome is not uncommon, the occurrence of childhood absence and BCECTS in the same child appears to be extremely rare, and this extraordinary event supports the hypothesis that CAE and BCECTS are two distinct epileptic conditions. However, recent interesting observations in animal models suggest that BCECTS and CAE could be pathophysiologically related and that genetic links could play a large role.

    A 62-year-old male with decompensated liver cirrhosis due to hepatitis C virus developed severe hepatic encephalopathy with status epileptic us. The blood ammonia level on admission was more than twice the normal level. Brain computed tomography and magnetic resonance imaging were normal. In addition, electroencephalogram showed diffuse sharp waves, consistent with hepatic encephalopathy. The status epilepticus was resolved after antiepileptic therapy (phenytoin sodium) and treatment for hepatic encephalopathy (Branched chain amino acids). The blood ammonia level normalized with the clinical improvement and the patient did not have a recurrence of status epilepticus after the end of the antiepileptic treatment. Additionally, the electroencephalogram showed normal findings. Thus, we diagnosed the patient as hepatic encephalopathy with status epilepticus. We consider the status epilepticus of this patient to a rare and interesting finding in hepatic encephalopathy.

    This review concerns the relation between most frequent thyroid gland diseases and diabetes mellitus in adult patients. Special attention is paid to autoimmune thyroiditis, Graves' disease, thyroid autoimmunity in pregnant diabetic women, and iodine metabolism. We focused on mechanisms leading to coexistence of both endocrine disorders, and on distinctions in the prevalence, diagnosis, clinical course and treatment of thyroid diseases in diabetic patients. The prevalence of thyroid diseases in diabetic patients is 2-3 times higher than in nondiabetic subjects; it raises with age, and is strongly influenced by female gender and autoimmune diabetes. Clinical relevance of thyroid diseases, especially in diabetic patients, significantly increases if it is associated with deteriorated function, which always cause a number problems with metabolic compensation of diabetes. Most serious consequences are increased frequency of hypoglycaemia in hypothyroidism and development of potentially life-threatening ketoacidosis in thyrotoxicosis. In spite of that, little attention is paid to the diagnosis of thyroid diseases in diabetics, as they are diagnosed in only about half of the patients. At the end, we provide recommendations for the thyroid disease screening and diagnosis in patients with diabetes mellitus based on our experience.

  17. Dynamic imaging of coherent sources reveals different network connectivity underlying the generation and perpetuation of epileptic seizures.

    Directory of Open Access Journals (Sweden)

    Lydia Elshoff

    Full Text Available The concept of focal epilepsies includes a seizure origin in brain regions with hyper synchronous activity (epileptogenic zone and seizure onset zone and a complex epileptic network of different brain areas involved in the generation, propagation, and modulation of seizures. The purpose of this work was to study functional and effective connectivity between regions involved in networks of epileptic seizures. The beginning and middle part of focal seizures from ictal surface EEG data were analyzed using dynamic imaging of coherent sources (DICS, an inverse solution in the frequency domain which describes neuronal networks and coherences of oscillatory brain activities. The information flow (effective connectivity between coherent sources was investigated using the renormalized partial directed coherence (RPDC method. In 8/11 patients, the first and second source of epileptic activity as found by DICS were concordant with the operative resection site; these patients became seizure free after epilepsy surgery. In the remaining 3 patients, the results of DICS / RPDC calculations and the resection site were discordant; these patients had a poorer post-operative outcome. The first sources as found by DICS were located predominantly in cortical structures; subsequent sources included some subcortical structures: thalamus, Nucl. Subthalamicus and cerebellum. DICS seems to be a powerful tool to define the seizure onset zone and the epileptic networks involved. Seizure generation seems to be related to the propagation of epileptic activity from the primary source in the seizure onset zone, and maintenance of seizures is attributed to the perpetuation of epileptic activity between nodes in the epileptic network. Despite of these promising results, this proof of principle study needs further confirmation prior to the use of the described methods in the clinical praxis.

    2014-01-01

    The assessment of consciousness is a fundamental element in the classification of epileptic seizures. It is, therefore, of great importance for clinical practice to develop instruments that enable an accurate and reliable measurement of the alteration of consciousness during seizures. Over the last few years, three psychometric scales have been specifically proposed to measure ictal consciousness: the Ictal Consciousness Inventory (ICI), the Consciousness Seizure Scale (CSS), and the Responsiveness in Epilepsy Scale--versions I and II (RES-I and RES-II). The ICI is a self-report psychometric instrument which retrospectively assesses ictal consciousness along the dimensions of the level/arousal and contents/awareness. The CSS has been used by clinicians to quantify the impairment of consciousness in order to establish correlations with the brain mechanisms underlying alterations of consciousness during temporal lobe seizures. The most recently developed observer-rated instrument is the RES-I, which has been used to assess responsiveness during epileptic seizures in patients undergoing video-EEG. The implementation of standardized psychometric tools for the assessment of ictal consciousness can complement clinical observations and contribute to improve accuracy in seizure classification.

    2014-10-01

    Ictal headaches are increasingly becoming the focus of research as more data demonstrate headaches existing as a sole manifestation of an epileptic event. Due to the difficulty in diagnosing the event as an epileptic phenomenon as opposed to a migraine, the condition is often misdiagnosed. This paper seeks to review the current published literature on ictal epileptic headaches as well as provide differentiation between ictal headaches and similarly presenting conditions. In doing so, we hope to improve the diagnosis of ictal headaches and thus improve patient care. We review two case studies that exemplify the potential of multiple conditions with comparable symptoms to ictal headaches, and discuss how to differentiate the variable diagnoses. As of the writing of this paper, there is no universally agreed upon set of features of ictal headaches; however, reviewing the current literature, there do seem to be several features that should be noted when treating patients. More research on the pathophysiology of ictal epileptic headaches needs to be done before the condition can be fully understood.

    Autoimmune lymphoproliferative syndrome (ALPS) is characterised by massive enlargement of the lymphoid organs, autoimmune cytopenias and a predisposition to develop lymphoid malignancies. The basic defect is a disturbance of the lymphocyte apoptosis, and a high number of circulating TCRab CD3(+)CD4(-)CD8(-) T-cells (double-negative T cells (DNT cells)). We describe a case of a 41-year-old man with fever, hepatosplenomegaly, multiple lymphadenopathy, autoimmune haemolytic anaemia and severe thrombocytopenia. Peripheral blood immunophenotyping revealed elevation of the characteristic DNT cells in 8% and high levels of interleukin 10. Histopathological analysis of lymph nodes showed lymphadenitis with paracortical hyperplasia. It was assumed as a probable diagnosis of ALPS, and the procedure was to medicate the patient with steroids. As a result, a significant clinical improvement was achieved, and he has been in remission for 2 years. To our knowledge, this is the first case reported in a Portuguese adult patient.

A thirty-year old man applied to the hospital with the complaint of uncommon-looking pupils and progressive blurring of vision in the left eye. On examination, uncorrected visual acuity (Snellen were 20/100 in the right eye and 20/640 in the left eye with amblyopia. On biomicroscopic examination, there were bilateral dense PPM and cataract in the left eye. Visual field analysis of right and left eyes showed great narrowing of visual fields. We present our case in order to emphasize that analysis of visual field of patients with PPM is as important as central vision when planning its treatment. For planning treatment of patients with PPM, visual impairment, size of pupillary opening, and visual field analysis should be considered.

    Full Text Available ABSTRACT The objective of this study was to compare postural balance among healthy older adults and Parkinson's disease (PD patients during one-legged stance balance. We recruited 36 individuals of both sexes and divided them into two groups: healthy older adults (HG, and individuals with PD (PG. All the participants were assessed through a single-leg balance test, with eyes open, during 30 seconds (30 seconds of rest across trials on a force platform. Balance parameters were computed from mean across trials to quantify postural control: center of pressure (COP area and mean velocity in both directions of movement, anterior-posterior and medial-lateral. Significant differences between-group were reported for area of COP (P=0.002 and mean velocity in anterior-posterior direction (P=0.037, where poor postural control was related to PD patients rather than to healthy individuals. One-legged stance balance was a sensitive task used to discriminate poor postural control in Parkinson individuals.

    Full Text Available Several avenues are being explored in the development of new anti-epileptic drugs (AEDs. For a number of years efforts have been directed towards compounds which may augment neuronal inhibition, and these efforts have resulted in the development of several valuable drugs. More recently, increased attention has been focused on the role which excitatory transmitters may play in epileptogenesis, and various substances which decrease excitation are currently being investigated at the preclinical level. Since considerable potential still resides in several of the drugs already on the market, resources have been spent on trying to modify/improve the chemical formula of some of these substances, and a number of new drugs has emerged as a result of this approach. The major accomplishments reviewed here in the development of new anti-epileptic drugs suggest that even more successful advances may be achieved in the near future.

    Full Text Available Non epileptic seizures were diagnosed in 20 (F:15, M:5 school children and adolescents by a positive provocative test consisting of induction and termination of the attack with suggestions and saline injection and normal ictal EEG. Patients were followed up for a period of two years. The major provocating factors were (a family problems, mainly conflict between the parents in 25%, (b problems in schooling in 20%, (c combination of both in 30%, (d sexual and physical abuse in 10% and (e undetectable in 15%. The frequency of the attacks were > 1/day in 55%, 1 - 6 / week in 25%, 1 - 3 / month in 15% and occasional in 5%. During follow up, 55% were free from attacks, 10% had recurrence occasionally for one year and free from it during the second year, 10% continued to get attacks and 25% were lost to follow up. In those free from attacks, multiple somatic complaints were reported by 30% of patients.

    Pallister-Killian syndrome (PKS) is a rare, sporadic, genetic disorder characterized by dysmorphic features, learning disability, and epilepsy. It is caused by a mosaic supernumerary isochromosome 12p (i[12p]). The i(12p) is rarely found in peripheral blood but it is present in skin fibroblasts. Recognition is essential for cytogenetic diagnosis. We describe a male aged 2 years 6 months and a female aged 11 years with PKS and epileptic spasms (ES). This type of seizure is not unusual in patients with brain malformations and with severe developmental delay, but it is sometimes difficult to recognize without video-electroencephalogram studies and could be mistaken for other types of seizure or behavioural manifestations. In these two patients with PKS, spasms had late onset, persisted beyond infancy, and were drug resistant. Clinicians should be aware of this possibility in PKS, which appears to be a rare cause of ES.

    We examined a total of 16 children with epileptic encephalopathy using fluorine-18-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission computed tomography (PET), magnetic resonance imaging (MRI) and electroencephalography.Children with infantile spasms showed significant mental retardation, severely abnormal electroencephalogram recordings, and bilateral diffuse cerebral cortex hypometabolism with 18F-FDG PET imaging.MRI in these cases showed brain atrophy, multi-micropolygyria, macrogyria, and porencephalia.In cases with Lennox-Gastaut syndrome, 18F-FDG PET showed bilateral diffuse glucose hypometabolism, while MRI showed cortical atrophy, heterotopic gray matter and tuberous sclerosis.MRI in cases with myoclonic encephalopathy demonstrated bilateral frontal and temporal cortical and white matter atrophy and 18F-FDG PET imaging showed bilateral frontal lobe atrophy with reduced bilateral frontal cortex, occipital cortex, temporal cortex and cerebellar glucose uptake.In children who could not be clearly classified, MRI demonstrated cerebral cortical atrophy and 18F-FDG PET exhibited multifocal glucose hypometabolism.Overall, this study demonstrated that the degree of brain metabolic abnormality was consistent with clinical seizure severity.In addition, 18F-FDG PET imaging after treatment was consistent with clinical outcomes.These findings indicate that 18F-FDG PET can be used to assess the severity of brain injury and prognosis in children with epileptic encephalopathy.

    2008-01-01

    Full Text Available DEFINITION Ohtahara syndrome (early infantile epileptic encephalopathy with suppression bursts, is the earliest developing form of epileptic encephalopathy. ETHIOLOGY It considered to be a result of static structural developing brain damage. CLINICAL PICTURE Variable seizures develop mostly within the first 10 days of life, but may occur during the first hour after delivery. The most frequently observed seizure type are epileptic spasms, which may be either generalized and symmetrical or lateralized. The tonic spasms may occur in clusters or singly, while awake and during sleep alike. The duration of spasms is up to 10 seconds, and the interval between spasms within cluster ranges from 9 to 15 seconds. In one third of cases, other seizure types include partial motor seizures or hemiconvulsions The disorder takes a progressively deteriorating course with increasing frequency of seizures and severe retardation of psychomotor development. DIAGNOSTIC WORKUP In the initial stage of Ohtahara syndrome, interictal EEG shows a pattern of suppression-burst with high-voltage paroxysmal discharges separated by prolonged periods of nearly flat tracing that last for up to 18 seconds. PROGNOSIS AND THREATMENT Half of the reported children having Ohtahara syndrome die in infancy. Anticonvulsant helps little in controlling the seizures and halting the deterioration of psychomotor development. Severe psychomotor retardation is the rule. With time, the disorder may evolve into West syndrome or partial epilepsy. Psychomotor development may be slightly better if the infants do not develop West and later Lennox-Gastaut syndrome.

    BACKGROUND: Research focused on the quality of life of epileptic patients began only very recently in China; in particular, most research has focused on children, but less on epileptic adults.OBJECTIVE: To survey and analyze 11 influential factors for quality of life in adults with epilepsy by using quality of life epilepsy-31 scale.DESIGN: Cross-sectional study.SETTING: Department of Neurology, First Hospital Affiliated to Jinan University; Department of Neurology, First Affiliated Hospital of Wenzhou Medical College.PARTICIPANTS: A total of 107 adults with epilepsy for longer than one year were selected from Department of Neurology, First Hospital Affiliated to Jinan University between March 2004 and December 2006. The included patients met the Classification and Diagnostic Criteria of Epileptic Attack published by International Anti-Epilepsy League in 1981, and they provided informed consent. METHODS: General states, including course, attack frequency, marriage status, educational level, occupational types, economic status, attack types, drug types, and drug amount, were recorded. There were seven aspects in the Quality of Life Epilepsy-31 scale, including attack worry, life satisfaction, emotion, vigor/tiredness, drug influence, cognitive function, and social function. The scores positively correlated with the quality of life. Possible influential factors for quality of life were analyzed by one-way ANOVA and multivariate regression analysis.MAIN OUTCOME MEASURES: Course, attack frequency, marriage status, educational level, occupational types, economic status, attack types, drug types, drug amount, age, and sex.RESULTS: A total of 107 epileptic patients were included in the final analysis. Influential factors for quality of life in epileptic adults included attack frequency, educational level, economic status, attack types, drug amount, age, and course of disease (P < 0.05). Among them, attack frequency negatively correlated with attack worry, life

    We studied respiratory function and Chest Wall kinematics in a large population of adult patients affected by slow course muscular dystrophies such as Limb-Girdle Muscular Dystrophy (LGMD, n=38), Becker Muscular Dystrophy (BMD, n=20) and Facio-Scapulo Humeral Dystrophy (FSHD, n=30), through standard spirometry and through the Optoelectronic Plethysmography, to measure the thoraco-abdominal motion during Quiet Breathing and Slow Vital Capacity maneuvers. Within the restrictive pulmonary syndrome characterizing LGMD and FSHD, several different thoraco-abdominal patterns compared to those of healthy subjects were present in the more advanced stages of the disease. These differences were present in the seated position, during the execution of a maximal maneuver such as Slow Vital Capacity. A global respiratory (both inspiratory and expiratory) muscle involvement was more pronounced in the LGMD and FSHD than in the BMD patients, and a significant reduction of abdominal contribution in wheelchair bound patients was observed. In conclusion, OEP technique is able to reveal mild initial modifications in the respiratory muscles in FSHD and LGMD patients, which could be helpful for functional and new therapeutic strategy evaluation.

    OBJECTIVE: To investigate the characteristics of sustained muscle activation during convulsive epileptic and psychogenic nonepileptic seizures (PNES), as compared to voluntary muscle activation. The main goal was to find surface electromyography (EMG) features that can distinguish between...... convulsive epileptic seizures and convulsive PNES. METHODS: In this case-control study, surface EMG was recorded from the deltoid muscles during long-term video-electroencephalography (EEG) monitoring in 25 patients and in 21 healthy controls. A total of 46 clinical episodes were recorded: 28 generalized...... tonic-clonic seizures (GTCS) from 14 patients with epilepsy, and 18 convulsive PNES from 12 patients (one patient had both GTCS and PNES). The healthy controls were simulating GTCS. To quantitatively characterize the signals we calculated the following parameters: root mean square (RMS) of the amplitude...

    Cervical column morphology was examined in adult patients with obstructive sleep apnoea (OSA) and compared with the cervical morphology of an adult control group with neutral occlusion, normal craniofacial morphology, and no history of sleep apnoea. The sleep apnoea group consisted of 91 patients, 16 females aged 29-59 years (mean 49.4 years) and 75 males aged 27-65 years (mean 49.0 years). All patients were diagnosed with OSA by overnight polysomnography. The control group consisted of 21 subjects, 15 females aged 23-40 years (mean 29.2 years) and 6 males aged 25-44 years (mean 32.8 years). From each individual, a visual assessment of the cervical column was performed on the radiograph. Differences in the cervical column morphology, between the genders and the groups were assessed by Fisher's exact test and the effect of age by logistic regression analysis. In the OSA group, 46.2 per cent had fusion anomalies of the cervical column and 5.5 per cent a posterior arch deficiency. Fusion anomalies occurred in 26.4 per cent as fusions between two cervical vertebrae. Block fusions occurred in 12.1 per cent and occipitalization in 14.3 per cent. A posterior arch deficiency occurred in 2.2 per cent as a partial cleft of C1 and in 3.3 per cent as dehiscence of C3 and C4. No statistical gender differences were found in the occurrence of morphological characteristics of the cervical column. The fusion anomalies of the cervical column occurred significantly more often in the OSA group. The results indicate that the morphological deviations of the upper cervical vertebrae play a role in the phenotypical subdivision and diagnosis of OSA.

    ·AIM: To describe the clinical characteristics of Turkish patients with intermediate uveitis(IU) and to investigate the effect of clinical findings and complications on final visual acuity(VA).·METHODS: We retrospectively analyzed the medical records of patients with IU who had at least 6mo of follow-up and were older than 16 y.· RESULTS: A total of 78 eyes of 45 patients were included in the study and the mean follow-up period was19.4mo. The mean age at the time of presentation was42.9s. Systemic disease associations were found in17.7% of cases; sarcoidosis(8.8%) and multiple sclerosis(6.6%) were the most common diseases. Recurrence rate(odds ratio=45.53; 95%CI: 2.181-950.58), vitritis equals to or more than 3+ cells(odds ratio =57.456; 95%CI: 4.154-794.79) and presenting with VA less than 20/40(odds ratio =43.81; 95% CI: 2.184-878.71) were also found as high risk factors for poor final VA. At the last follow-up examination, 67.9% of eyes had VA of 20/40 or better.·CONCLUSION: IU is frequently seen at the beginning of the fourth decade of life. The disease is most commonly idiopathic in adult Turkish patients. Patients with severe vitritis at presentation and patients with frequent recurrences are at high risk for poor visual outcome.

    AIM: To determine if inflammatory bowel disease (IBD) is a risk factor for osteoporosis in adult Sri Lankans. METHODS: We identified eligible subjects from among consecutive patients diagnosed with IBD who attended our outpatient clinic. We included only patients aged between 20 and 70 years. Patients who were pregnant, had significant comorbidity, or were on calcium supplements or treatment for osteoporosis within the past 6 mo, were excluded. Healthy, age- and sex-matched controls were also recruited, in a control to patient ratio of 3:1. Both groups were screened for osteoporosis using peripheral dual energy X-ray absorptiometry scanning. RESULTS: The study population consisted of 111 IBD patients (male:female = 43:68; mean age 42.5 years) and 333 controls (male:female = 129:204; mean age 43.8 years). The occurrence of osteoporosis among IBD patients (13.5%) was significantly higher than among controls (4.5%) ( P = 0.001). The frequency of osteoporosis was not significantly different between ulcerative colitis (14.45%) and Crohn's disease (10.7%). However, on multivariate analysis, only age ( P = 0.001), menopause ( P = 0.024) and use of systemic steroids ( P < 0.001) were found to be associated independently with the occurrence of osteoporosis, while IBD, severity of disease, number of relapses, duration of illness or treatment other than systemic steroids were not. CONCLUSION: IBD does not appear to be an independent risk factor for the occurrence of osteoporosis in this population. However, the use of systemic steroids was a risk factor.

    By the means of computing approximate entropy (ApEn) of video-EEG from some clinical epileptic, ApEn of EEG with epileptiform discharges is found significantly different from that of EEG without epileptiform discharges, (p=0. 002). Meanwhile, dynamic ApEn shows consistent change of EEG signal withdischarges of epileptic waves inside. These results suggest that ApEn may be a useful tool for automatic recognition and detection of epileptic activity and for understanding epileptogenic mechanism.

    There is increasing demand from adult patients for orthodontic treatment, either purely for aesthetics, to improve aesthetics or function following previous disease, or to facilitate the stabilization, restoration or replacement of teeth. Orthodontics may have a major role in the rehabilitation of patients suffering the effects of advanced periodontal disease, but there are a number of important factors to be considered in the management of such patients if the optimal outcome is to be obtained. This paper summarizes important aspects of treatment and the potential complications and how to avoid them.

    2013-06-01

    This paper explores the three different methods to explicitly recognize the healthy and epileptic EEG signals: Modified, Improved, and Advanced forms of Generalized Fractal Dimensions (GFD). The newly proposed scheme is based on GFD and the discrete wavelet transform (DWT) for analyzing the EEG signals. First EEG signals are decomposed into approximation and detail coefficients using DWT and then GFD values of the original EEGs, approximation and detail coefficients are computed. Significant differences are observed among the GFD values of the healthy and epileptic EEGs allowing us to classify seizures with high accuracy. It is shown that the classification rate is very less accurate without DWT as a preprocessing step. The proposed idea is illustrated through the graphical and statistical tools. The EEG data is further tested for linearity by using normal probability plot and we proved that epileptic EEG had significant nonlinearity whereas healthy EEG distributed normally and similar to Gaussian linear process. Therefore, we conclude that the GFD and the wavelet decomposition through DWT are the strong indicators of the state of illness of epileptic patients.

  1. Enhancement of asynchronous release from fast-spiking interneuron in human and rat epileptic neocortex.

    Man Jiang

    Full Text Available Down-regulation of GABAergic inhibition may result in the generation of epileptiform activities. Besides spike-triggered synchronous GABA release, changes in asynchronous release (AR following high-frequency discharges may further regulate epileptiform activities. In brain slices obtained from surgically removed human neocortical tissues of patients with intractable epilepsy and brain tumor, we found that AR occurred at GABAergic output synapses of fast-spiking (FS neurons and its strength depended on the type of connections, with FS autapses showing the strongest AR. In addition, we found that AR depended on residual Ca²⁺ at presynaptic terminals but was independent of postsynaptic firing. Furthermore, AR at FS autapses was markedly elevated in human epileptic tissue as compared to non-epileptic tissue. In a rat model of epilepsy, we found similar elevation of AR at both FS autapses and synapses onto excitatory neurons. Further experiments and analysis showed that AR elevation in epileptic tissue may result from an increase in action potential amplitude in the FS neurons and elevation of residual Ca²⁺ concentration. Together, these results revealed that GABAergic AR occurred at both human and rat neocortex, and its elevation in epileptic tissue may contribute to the regulation of epileptiform activities.

    Full Text Available A 52-year-old woman was admitted with a 3 weeks history of periorbital edema and lips swelling. She developed several subcutaneous firm erythematous papules and nodules on the face, scalp and two indurated plaques on the upper back and left forearm. These lesions grew rapidly. The patient had a positive history of epileptic seizures since childhood. General examination was normal. There was a mild pitting edema on her hands and feet. Laboratory data were within normal limits. Histopathological examination revealed a well circumscribed accumulation of mucin in the dermis. Alcian blue stain was positive. Clinical and histopathological findings followed by spontaneous resolution of the lesions within a period of 4 months was compatible with diagnosis of self-healing cutaneous mucinosis. Herein we report the first case of self-healing cutaneous mucinosis associated with epilepsy.

    Humidification of inhaled gases has been standard of care in mechanical ventilation for a long period of time. More than a century ago, a variety of reports described important airway damage by applying dry gases during artificial ventilation. Consequently, respiratory care providers have been utilizing external humidifiers to compensate for the lack of natural humidification mechanisms when the upper airway is bypassed. Particularly, active and passive humidification devices have rapidly evolved. Sophisticated systems composed of reservoirs, wires, heating devices, and other elements have become part of our usual armamentarium in the intensive care unit. Therefore, basic knowledge of the mechanisms of action of each of these devices, as well as their advantages and disadvantages, becomes a necessity for the respiratory care and intensive care practitioner. In this paper, we review current methods of airway humidification during invasive mechanical ventilation of adult patients. We describe a variety of devices and describe the eventual applications according to specific clinical conditions.

    Full Text Available Introduction. Nowadays acute infectious-inflammatory processes of upper respiratory tract, including acute epiglottitis retain a high proportion among human pathology. In the literature acute epiglottitis is allocated into an independent nosology as severe acute phlegmonous bacterial inflammation of the epiglottis and hypopharynx. There are currently no clear guidelines on how to classify an acute epiglottitis, as well as protocols for patients at various stages of the pathological process. According to common belief, Haemophilus influenzae type -B (Haemophilus influenza type b (Hib is the most common cause of epiglottitis. At present, the main etiological role in the genesis of acute epiglottitis in children belongs to haemophilus influenzae. In adults the causes of the disease are beta hemolytic streptococci groups A, B, pneumococcus, Klebsiella, Pseudomonas, Staphylococcus aureus, herpes simplex virus (type 1 and parainfluenza, and others.The aim of this work is to study: the mucosal microflora of the epiglottis in adult patients with acute epiglottitis and to study sensitivity of certain isolates to antimicrobial agents. Material & methods. 86 adult patients with acute epiglottitis were observed: 36 with abscess form of epiglottitis and 50 - with infiltrative. Microbiological analysis of mucosal swab samples taken from hypopharynx were conducted by the conventional technology: for seeding solid or liquid nutrient medium, followed by allocation of isolith and its microscopic, biochemical and serological identification. Microorganisms were classified according to schemes of Bergy. Antimicrobial susceptibility of each strain was determined in accordance with the guidelines. We used discs with antibacterial drugs. The availability of sensitive and resistant strains of microorganisms to antibiotics was assessed. A mucous membrane of the epiglottis was analyzed through microbiological investigation in 86 patients with acute epiglottitis. As a

    Objective: To investigate the effects of epilepsy and anti-epileptic drugs(AEDs) on bone mineral density(BMD) of patients with epilepsy. Methods: 160 cases aged between 20 and 60 years old were selected as subjects. All of them had the disease for more than nine months and had been taking AEDs for more than six months. All were free of other diseases and none was taking any medication that might interfere with bone metabolism other than AEDs. BMDs at the right heel were measured with the ultrasonic BMD instrument. Detailed clinical information of each patient were obtained by the researcher. All of the related risk factors in the data were stratified according to certain degree. Fifty normal controls were involved. Then single factor chi-square test and multivariate logistic regression analysis were analyzed. Results: There was statistically significant difference between epileptics and normal group in BMD (P0.05). Multivariate logistic regression analysis identified GTCS,polytherapy and the duration of anticonvulsant therapy were as the related and independent risk factors(OR value, 1.105, 5.710, 5.820, respectively; P<0.05). Conclusion: The results indicate that both epilepsy and anti-epileptic drugs can lead to the change of BMD of patients with epilepsy, and GTCS, polytherapy and the duration of anticonvulsant therapy are important risk factors of low BMD. It can be used as valuable reference to prevent bone mass loss and fractures of epileptic patients effectively.%目的:研究癫痫病本身及抗癫痫药物(AEDs)与癫痫患者骨密度(BMD)异常的相关性.方法:采用超声法对160例年龄在20~60岁、病程≥9个月、AEDs治疗时间≥6个月的癫痫患者进行BMD检测,收集相关的临床资料并设置正常对照组50例.根据癫痫的病程、发作类型、服用AEDs的数量及种类、治疗时间分组,分析各组临床指标与骨量异常的相关性.结果:癫痫患者组BMD异常率与正常对照组比较有显著差

    An 18-year-old female presented with two seizures induced by photic stimulation. She had a positive family history for migraine and a history of febrile convulsions. Since the age of 13 she had suffered from migraine attacks with aura. A brain computerized tomography with contrast enhancement was negative and several electroencephalograms showed a photoparoxysmal response. At the age of 18 she had a partial secondary generalized seizure after photic stimulation during routine electroencephalogram. The onset of seizure was in the occipital region. Two days later, the patient presented with a typical migrainous attack with aura. Interictal apomorphine test (1.5 mg s.c.) blocked the photoparoxysmal response. According to Quesnay, dopaminergic failure of the occipital cortex may account for both epileptic and migraine features.

    In this paper we have proposed a novel amplitude suppression algorithm for EEG signals collected during epileptic seizure. Then we have proposed a measure of chaoticity for a chaotic signal, which is somewhat similar to measuring sensitive dependence on initial conditions by measuring Lyapunov exponent in a chaotic dynamical system. We have shown that with respect to this measure the amplitude suppression algorithm reduces chaoticity in a chaotic signal (EEG signal is chaotic). We have compared our measure with the estimated largest Lyapunov exponent measure by the largelyap function, which is similar to Wolf's algorithm. They fit closely for all but one of the cases. How the algorithm can help to improve patient specific dosage titration during vagus nerve stimulation therapy has been outlined.

    Background and aims Aging is a multifactorial process that elicits changes in the duration and quality of sleep. Polysomnography is considered to be the standard examination for the analysis of sleep and consists of the simultaneous recording of selected physiological variables during sleep. Objective The objective of this study was to use polysomnography to compare sleep reported by senior citizens. Methods We selected 40 patients, both male and female, with ages ranging from 64 to 89 years from the Center for the Study of Aging at the Federal University of São Paulo. Patients answered questions about sleep on the Comprehensive Geriatric Assessment and underwent polysomnography. Results The results were compared, and agreement between perceived sleep and polysomnography was found in several areas. There was an association between difficulty sleeping and sleep onset latency (p=0.015), waking up at night with sleep onset latency (p=0.005), total sleep time with daytime sleepiness (0.005) and snoring (0.027), sleep efficiency with sleepiness (0.004), snoring (0.033) and pause in breathing (p=0.024), awakenings with snoring (p=0.012) and sleep apnea with pauses in breathing (p=0.001). Conclusion These results suggest that the older adult population have a good perception of their sleep. The questionnaires aimed at this population should be used as an alternative to polysomnography. PMID:26483948

    Full Text Available Hearing loss is a significant public health problem. The incidence is difficult to establish because of the lack of data in people under age three, but is estimated about 1 per thousand for severe and profound hearing loss.A cochlear implant (CI is a device that converts sounds into electrical energy that triggers a sensation of hearing. The IC is indicated in patients with severe bilateral sensorineural hearing loss with null or poor benefit use of hearing aids.The general objective of this project is to understand the experiences of adult patients with severe-profound sensorineural hearing loss with IC postlingually throughout the implementation process.A personal vision of those implemented will allow us to learn how to face the possibility to hear and interact with their environment, applying this information to improve health care provided to them and identifying those areas where such assistance should be improved. Also allow us to compare the initial expectations and have been achieved, creating realistic expectations for future candidates.For its development we have designed a qualitative study, based on the principles and procedures of grounded theory, semistructured interviews, participant observation and discussion groups.The data will be analyzed using the software Nudist ViVo 9.

    The aim of this study was to analyze the prevalence and antibiotic resistance of Staphylococcus aureus strains from 118 tonsillectomized adults due to recurrent tonsillitis (RT). The study included strains isolated from the tonsillar surface prior to tonsillectomy, recovered from the tonsillar core at the time of surgery, and from the posterior throat 2-4 weeks after the procedure. Susceptibility of isolates to 19 antibiotics was tested in line with the Clinical and Laboratory Standards Institute recommendations. Irrespective of the stage, the most commonly isolated bacteria were gram-positive cocci, and among them S. aureus. The tonsillar core was the most common site of S. aureus isolation (30.5%), followed by the tonsillar surface (10.8%) and the posterior pharynx (5.9%). This difference turned out to be statistically significant (p aureus seems to be the most common pathogen isolated from patients tonsillectomized due to RT. Staphylococcal isolates associated with RT are present mostly within the tonsillar core and susceptible to most antibiotics. They are typically isolated from patients between 21 and 30 years of age. Tonsillectomy results in less frequent isolation of S. aureus strains.

    Liver abnormalities in the course of Adult Onset Still's Disease (AOSD), both in form of hepatomegaly and elevation of hepatic enzymes, have been reported in up to three-quarts of the affected patients. These abnormalities may reflect disease activity or may be induced by drugs. Only in a few of this patients a liver biopsy was performed. However liver histology has shown, generally, non specific abnormalities or even normal pictures. We have recently observed a 47-year-old woman with a febrile illness started five months before, who after pertinent investigation was diagnosed as AOSD (according to criteria of Yamaguchi et al.). Apart from laboratory findings characteristic of an inflammatory disease, in absence of drug therapies the biochemical data showed raised levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and aminoglutamil transferase. Serological tests for either viral hepatitis viruses (HAV, HBV, HCV) or other viruses were negative. Ultrasonographic examination of gallbladder and bile ducts did not find gallstones or other abnormalities. A liver biopsy was performed, which histopathologic examination showed moderate fatty methamorphosis with focal areas of hepatocellular swelling with minimal necrosis, mild Kuppfer cell hyperplasia, portal and sinusoidal infiltrates of mononuclear cells. This picture consisted with the diagnosis of an acute unspecific reactive hepatitis.

    Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease and it encompasses a spectrum from simple steatosis to steatohepatitis, fibrosis, or cirrhosis. The mechanisms involved in the occurrence of NAFLD and its progression are probably due to a metabolic profile expressed within the context of a genetic predisposition and is associated with a higher energy intake. The metabolic syndrome (MS) is a cluster of metabolic alterations associated with an increased risk for the development of cardiovascular diseases and diabetes. NAFLD patients have more than one feature of the MS, and now they are considered the hepatic components of the MS. Several scientific advances in understanding the association between NAFLD and MS have identified insulin resistance (IR) as the key aspect in the pathophysiology of both diseases. In the multi parallel hits theory of NAFLD pathogenesis, IR was described to be central in the predisposition of hepatocytes to be susceptible to other multiple pathogenetic factors. The recent knowledge gained from these advances can be applied clinically in the prevention and management of NAFLD and its associated metabolic changes. The present review analyses the current literature and highlights the new evidence on the metabolic aspects in the adult patients with NAFLD. PMID:27610012

    It is an open-ended challenge to accurately detect the epileptic seizures through electroencephalogram (EEG) signals. Recently published studies have made elaborate attempts to distinguish between the normal and epileptic EEG signals by advanced nonlinear entropy methods, such as the approximate entropy, sample entropy, fuzzy entropy, and permutation entropy, etc. Most recently, a novel distribution entropy (DistEn) has been reported to have superior performance compared with the conventional entropy methods for especially short length data. We thus aimed, in the present study, to show the potential of DistEn in the analysis of epileptic EEG signals. The publicly-accessible Bonn database which consisted of normal, interictal, and ictal EEG signals was used in this study. Three different measurement protocols were set for better understanding the performance of DistEn, which are: i) calculate the DistEn of a specific EEG signal using the full recording; ii) calculate the DistEn by averaging the results for all its possible non-overlapped 5 second segments; and iii) calculate it by averaging the DistEn values for all the possible non-overlapped segments of 1 second length, respectively. Results for all three protocols indicated a statistically significantly increased DistEn for the ictal class compared with both the normal and interictal classes. Besides, the results obtained under the third protocol, which only used very short segments (1 s) of EEG recordings showed a significantly (p entropy algorithm. The capability of discriminating between the normal and interictal EEG signals is of great clinical relevance since it may provide helpful tools for the detection of a seizure onset. Therefore, our study suggests that the DistEn analysis of EEG signals is very promising for clinical and even portable EEG monitoring.

    Background and objectives Patient knowledge of lung function (ie, forced expiratory volume in 1 s [FEV1]% predicted) and the intended benefits of their prescribed pulmonary medications might play an important role in medication adherence, but this relationship has not been examined previously in patients with cystic fibrosis (CF). Methods All patients diagnosed with CF and without prior lung transplantation were invited to complete knowledge and self-reported medication adherence questionnaires during routine outpatient visits to the Adult CF Clinic, St Paul’s Hospital, Vancouver, Canada from June 2013 to August 2014. Results A total of 142 out of 167 (85%) consecutive adults attending CF clinic completed patient knowledge and medication adherence survey questionnaires. Sixty-four percent of the patients recalled their last FEV1% predicted value within 5%, and 70% knew the intended benefits of all their prescribed medications. Self-reported adherence rates were highest for inhaled antibiotics (81%), azithromycin (87%), and dornase alpha (76%) and lowest for hypertonic saline (47%). Individuals who knew their FEV1% predicted value within 5% were more likely to self-report adherence to dornase alpha (84% vs 62%, P=0.06) and inhaled antibiotics (88% vs 64%, P=0.06) compared to those who did not, but these associations were not statistically significant. There were no significant associations observed between patient knowledge of intended medication benefits and self-reported medication adherence. Conclusion Contrary to our hypothesis, disease- and treatment-related knowledge was not associated with self-reported medication adherence. This suggests other barriers to medication adherence should be targeted in future studies aiming to improve medication adherence in adults with CF.

    Full Text Available Objective: to identify the factors influencing the stigmatization in patients with epilepsy. Patients and methods. The investigation enrolled 71 epileptic patients aged 14 to 50 years. They were divided into two age groups: 30 adolescents aged 14–17 years and 41 adults aged 18–50 years. Results and discussion. Examinations of 71 patients with epilepsy could identify 4 factors influencing their stigmatization: individual traits; activity and relations in the group; the effect of a drug and its adherence in patients; relationships in the family and its response to the disease. The authors’ new screening procedure was employed to determine the leading causes of stigmatization for each age group and to show differences in the specific features of stigmatization (the leading factor of stigmatization in patients of different age. The major factor of stigmatization in the epileptic adolescents was found to be relationships in the family and its response to the disease. Its chief cause in the adults was their principal activity (studies at a higher education establishment or work and group relations. The epileptic patients were shown to need psychological care. The developed screening procedure will be useful in planning psycho-correction measures and rehabilitation programs.

    Functional magnetic resonance imaging (fMRI) has the potential to replace the intracarotid amobarbital procedure (IAP) in presurgical evaluation of patients with epilepsy. In this study, we compared fMRI verb generation (VG) and semantic decision/tone decision (SDTD) tasks and the IAP in their ability to localize language functions in patients with epilepsy undergoing presurgical evaluation. We enrolled 50 healthy controls to establish normal language activation patterns for VG and SDTD tasks at 3 or 4 T, and to design language regions of interest (ROIs) that were later applied to 38 patients with epilepsy (28 of 38 also underwent the IAP). We calculated laterality indices (LIs) for each task for each subject based on the ROIs, and we used general linear modeling to analyze the fMRI data. All healthy and epileptic subjects activated language areas with both fMRI tasks. We found significant correlations in language lateralization between the fMRI tasks (r=0.495, Planguage. In the general linear modeling, only the SDTD task significantly contributed to the determination of language lateralization in patients with epilepsy undergoing presurgical evaluation. Results indicate a moderate convergent validity between both fMRI language tasks and between IAP and fMRI tasks. The results of this study indicate that either of these fMRI tasks can be used for language lateralization in patients with epilepsy undergoing presurgical evaluation, but that the SDTD task is likely to provide more information regarding language lateralization than the VG task.

    after surgery,there was no evidence of fixation failure or graft resorption in the shoulders.No one underwent revision surgery.Overall,most of the patients had satisfactory pain relief and daily living activities postoperatively at the time of the latest follow-up.Conclusions The anterior dislocation of the shoulder in the epileptic patients is really uncommon.The treatment of the secondary recurrent anterior dislocations of the shoulder associated with severe osseous deficiency is quite difficult,due to the unacceptably high rate of re-dislocation after the open or arthroscopic reconstruction surgery of the Bankart lesion.Our study assessed the effects of Latarjet procedure on the radiological and clinical results in seven cases with severe glenoid osseous deficiency accompanied with epileptic seizure disorders and recurrent anterior dislocation of shoulder.The results suggested that when treating patients with an epileptic seizure disorder and recurrent anterior glenohumeral instability,effective control of the epileptic seizures is one of the most important methods to reduce the incidence of post-operative recurrent dislocation,because a compliant patient was very important for a successful clinical outcome.The Latarjet procedure can provide a satisfied reconstruction of shoulder stability,but the possibility of re-dislocation and osteoarthritis should be also noticed.We recommend a high index of suspicion when treating patients with a seizure disorder who have anterior shoulder instability,and we recommend making a preoperative CT scan,if there is a strong likelihood that a coracoid transfer will be used at surgery.This enables the diagnosis of a coracoid fracture nonunion to be made prior to surgery and helps to determine whether there is sufficient bone to allow a Latarjet procedure to be performed.However,it needs further investment to choose an appropriate surgery procedure for the untreated epileptic patients.

    Full Text Available Introduction: Teratomas are congenital tumors consisting of derivatives from the ectoderm, endoderm and mesoderm germ cell layers. A teratoma is considered to be a non-seminomatous germ cell tumor and is typically located in either the sacrococcygeal region or in the gonads. Giant retroperitoneal teratomas in adults are even rarer, with only a few cases previously described in the literature. Case report: A 35-year-old male patient with severe nausea and vomiting was taken to the emergency ward of Hamadan Be’sat Hospital. He had not been feeling well, and had suffering from abdominal pain for a month. A physical examination showed some concretion in the right side of his abdomen. A CT scan of his abdomen and pelvis with IV and oral contrast re-vealed that the concretion was formed by aggregates of solid, cystic, and calcareous compo-nents. It compressed stomach and caused the rotation of the stomach around its longitudinal axis. Conclusion: Following the diagnosis, we performed a laparotomy and respected a concretion with dimension 20?25?22cm. Interestingly, we found out all mature tissues within the con-cretion in the pathology examination of an adequate sample (such as trachea, bone, GI lu-men….

    2016-01-01

    Introduction: Tetanus is a severe and potentially fatal infection caused by the bacterium Clostridium tetani. Of all the cases described in literature, generalized tetanus is by far the most common presentation, but it may also present as neonatal tetanus, cephalic tetanus, and localized tetanus, the latter two being much rarer. In this case report, we present the rare form of this disease, i.e., localized tetanus in an adult male with a history of minimal trauma as well as a late, unusual mode of presentation. Case Report: A 35-year-old Caucasian male presented with an acutely painful, swollen right thumb associated with a small superficial collection on the dorsal aspect of the base of the thumb. A formal wound exploration and washout were carried out in theater, however, at the time of tourniquet inflation, the right hand went into a carpopedal spasm and remained in that position until an infusion of a muscle relaxant was given. The findings were consistent with a case of localized tetanus. The patient was treated with human immunoglobulin and tetanus toxoid and safely discharged home 48 h later without any complications. Conclusion: This case report emphasizes the importance of the recognition of a rare form of this fatal infectious disease, which may present with prodromal symptoms before the generalized form shows its clinical effects. Moreover, the astute clinician should be aware of the variable presentations of this infectious disease, with early identification greatly reducing the associated risks of morbidity and mortality.

  17. Age-Dependency of Location of Epileptic Foci in "Continuous Spike-and-Waves during Sleep": A Parallel to the Posterior-Anterior Trajectory of Slow Wave Activity.

    Background Epileptic encephalopathy with continuous spike-and-waves during sleep (CSWS) occurs during childhood and is characterized by an activation of spike wave complexes during slow wave sleep. The location of epileptic foci is variable, as is etiology. A relationship between the epileptic focus and age has been shown in various focal epilepsies following a posterior-anterior trajectory, and a link to brain maturation has been proposed.We hypothesize that in CSWS, maximal spike wave activity, corresponding to the epileptic focus, is related to age and shows a posterior-anterior evolution. Findings In a retrospective cross-sectional study on CSWS (22 EEGs of 22 patients aged 3.1-13.5 years), the location of the epileptic focus is related to age and follows a posterior-anterior course. Younger patients are more likely to have posterior foci than older ones. Conclusions We propose that the posterior-anterior trajectory of maximal spike waves in CSWS might reflect maturational changes of maximal expression of sleep slow waves, which follow a comparable course. Epileptic spike waves, that is, "hyper-synchronized slow waves" may occur at the place where the highest and therefore most synchronized slow waves meet brain tissue with an increased susceptibility to synchronization.

    Many cochlear implant candidates express hopes of enjoying music following implantation. Our aim was to assess the appreciation of music after cochlear implantation in adult patients. Thirty-five out of 45 cochlear implantees (78%) from the North East Programme responded to a questionnaire. Only 16 out of 35 patients (46%) listened to music after implantation. Enjoyment of music on a self-assessment scale was graded a mean of 8.7/10 before deafness but only 2.6/10 after implantation. Listening to music after implantation was more likely in younger patients, those with higher speech perception scores and those with a shorter length of deafness, but was not found to be related to gender, type of implant, processing strategy, time since implant or music enjoyment before becoming deaf. Appreciation of music after cochlear implantation is disappointingly low. Future developments in implant technology should strive to improve satisfaction with music listening.

The aim of this study was to assess the motivation of adult female patients seeking orthodontic treatment, and classify the patients according to their motivations.Methods: This study used Q-methodology as the main tool. Q-samples were collected and categorized (35 items. Forty-two adult female patients were interviewed before treatment as the P-sample, and their responses were categorized into the Q-methodology grid. Participants were asked to rank-order a set of 35 statements (Q-sample from “agree most” to “disagree most” (Q-sorting. The finished Q-grids were analyzed using PQ method 2.35.Results: Four main factors were identified based on how adult female patients ranked statements: factor 1, patients who focus on their self-perception of their appearance; factor 2, patients who are concerned about the esthetics and function of their teeth; factor 3, patients who are easily influenced by others; factor 4, patients who want to improve their confidence and avoid negative thoughts caused by their teeth. The remaining patients who had other views did not match any of the above four groups.Conclusion: The motivations of adult female patients seeking orthodontic treatment are complex. This study found that most adult female patients fell into one of four typical factor groups. Our findings may improve the adherence of adult female patients by developing a more ideal treatment program. Keywords: adult female patients, orthodontic treatment, Q-methodology

    We propose a novel approach for detecting precursors to epileptic seizures in intracranial electroencephalograms (iEEG), which is based on the analysis of system dynamics. In the proposed scheme, the largest Lyapunov exponent of the discrete wavelet packet transform (DWPT) of the segmented EEG signals is considered as the discriminating features. Such features are processed by a support vector machine (SVM) classifier to identify whether the corresponding segment of the EEG signal contains a precursor to an epileptic seizure. When consecutive EEG segments contain such precursors, a decision is made that a precursor is in fact detected. The proposed scheme is applied to the Freiburg dataset, and the results show that seizure precursors are detected in a time frame that unlike other existing schemes is very much convenient to patients, with sensitivity of 100% and negligible false positive detection rates.

    Directed graphs (digraphs) derived from interictal periods of intracerebral EEG (iEEG) recordings can be used to estimate the leading interictal epileptic regions for presurgery evaluations. For this purpose, quantification of the emittance contribution of each node to the rest of digraph is important. However, the usual digraph measures are not very well suited for this quantification. Here we compare the efficiency of recently introduced local information measure LI and a new measure called total global efficiency with classical measures like global efficiency, local efficiency and node degree. For evaluation, the estimated leading interictal epileptic regions based on five measures are compared with seizure onset zones obtained by visual inspection of epileptologists for five patients. The comparison revealed the superior performance of LI measure. We showed efficiency of different digraph measures for the purpose of source and sink node identification. PMID:20952817

    The gamma-aminobutyric acid type A receptor β3 gene (GABRB3) encodes the β3-subunit of the gamma-aminobutyric acid type A (GABAA ) receptor, which mediates inhibitory signalling within the central nervous system. Recently, GABRB3 mutations have been identified in a few patients with infantile spasms and Lennox-Gastaut syndrome. We report the clinical and electrographic features of a novel case of GABRB3-related early-onset epileptic encephalopathy. Our patient presented with neonatal hypotonia and feeding difficulties, then developed pharmacoresistant epileptic encephalopathy, characterized by multiple seizure types from 3 months of age. Electroencephalography demonstrated ictal generalized and interictal multifocal epileptiform abnormalities. Using a SureSelectXT custom multiple gene panel covering 48 early infantile epileptic encephalopathy/developmental delay genes, a novel de novo GABRB3 heterozygous missense mutation, c.860C>T (p.Thr287Ile), was identified and confirmed on Sanger sequencing. GABRB3 is an emerging cause of early-onset epilepsy. Novel genetic technologies, such as whole-exome/genome sequencing and multiple gene panels, will undoubtedly identify further cases, allowing more detailed electroclinical delineation of the GABRB3-related genotypic and phenotypic spectra.

    During the last decade, many clinical and pathophysiological aspects of sleep-related epileptic and non-epileptic paroxysmal behaviors have been clarified. Advances have been achieved in part through the use of intracerebral recording methods such as stereo-electroencephalography (S-EEG), which has allowed a unique "in vivo" neurophysiological insight into focal epilepsy. Using S-EEG, the local features of physiological and pathological EEG activity in different cortical and subcortical structures have been better defined during the entire sleep-wake spectrum. For example, S-EEG has contributed to clarify the semiology of sleep-related seizures as well as highlight the specific epileptogenic networks involved during ictal activity. Moreover, intracerebral EEG recordings derived from patients with epilepsy have been valuable to study sleep physiology and specific sleep disorders. The occasional co-occurrence of NREM-related parasomnias in epileptic patients undergoing S-EEG investigation has permitted the recordings of such events, highlighting the presence of local electrophysiological dissociated states and clarifying the underlying pathophysiological substrate of such NREM sleep disorders. Based on these recent advances, the authors review and summarize the current and relevant S-EEG literature on sleep-related hypermotor epilepsies and NREM-related parasomnias. Finally, novel data and future research hypothesis will be discussed.

    Full Text Available The correlation between small spikes in Rolandic area and epileptic seizures was investigated. In this thesis, small spikes in Rolandic area were found in 118 cases recorded by video electroencephalogram (VEEG monitoring. And the 118 patients were chose to be studied in our research. Among the 118 cases, 62 were male and 56 were female. The youngest was only 3-month-old, and the eldest was 4 years and 5 months old. Eighty-five cases were between 3 months and 2 years old which accounted for 72.03%. There were 101 patients (85.59% having seizures: 42 cases (35.59% of febrile convulsion, 35 (29.66% of benign infantile convulsions with mild gastroenteritis (BICG and 24 (20.34% of epilepsy; 17 cases (14.41% of non-epileptic seizures. Hence, there is high correlation between infantile small spikes in Rolandic area and epileptic seizures. But it does not indicate any specificity. Whether small spikes in Rolandic area can be used as certain evidence to diagnose epilepsy and locate the onset of lesions requires further study to confirm.

    Full Text Available OBJECTIVE: The purpose of this study was to review and compare the differences between mandibular fractures in young and adult patients. MATERIAL AND METHODS: Patients treated at the Oral and Maxillofacial Department of Dicle University during a five-year period between 2000 and 2005 were retrospectively evaluated with respect to age groups, gender, etiology, localization and type of fractures, treatment methods and complications. RESULTS: 532 patients were included in the study, 370 (70% males and 162 (30% females, with a total of 744 mandibular fractures. The mean age of young patients was 10, with a male-female ratio of 2:1. The mean age of adult patients was 28, with a male-female ratio of 3:1. The most common causes of injury were falls (65% in young patients and traffic accidents (38% in adults. The most common fracture sites were the symphysis (35% and condyle (36% in young patients, and the symphysis in adults (36%. Mandibular fractures were generally treated by arch bar and maxillomandibular fixation in both young (67% and adult (39% patients, and 43% of the adult patients were treated by open reduction and internal fixation. CONCLUSION: There was a similar gender, monthly and type of treatment distribution in both young and adult patients in the southeast region of Turkey. However, there were differences regarding age, etiology and fracture site. These findings between young and adult patients are broadly similar to those from other studies. Analysis of small differences may be an important factor in assessing educational and socioeconomic environments.

    Fever-induced refractory epileptic encephalopathy of school-age children is a rare epileptic syndrome that causes difficulties in diagnosis at the initial stage of disease. It is characterized by sudden onset with multifocal refractory status epilepticus in previously healthy children with normal development. Later, children suffer from resistant focal epilepsy in the combination with cognitive deficit and behavioral difficulties. Authors describe a clinical case of fever-induced refractory epileptic encephalopathy of school-age children in a child of 7 years old. Aspects of etiology, pathogenesis, clinical manifestation, differential diagnosis, treatment and prognosis of the disease are discussed.

    In this study, the nonlinear properties of the electroencephalograph (EEG) signals are investigated by comparing two sets of EEG, one set for epileptic and another set for healthy brain activities. Adopting measures of nonlinear theory such as Lyapunov exponent, correlation dimension, Hurst exponent, fractal dimension, and Kolmogorov entropy, the chaotic behavior of these two sets is quantitatively computed. The statistics for the two groups of all measures demonstrate the differences between the normal healthy group and epileptic one. The statistical results along with phase-space diagram verify that brain under epileptic seizures possess limited trajectory in the state space than in healthy normal state, consequently behaves less chaotically compared to normal condition.

    Epilepsy is a neurological disorder which can, if not controlled, potentially cause unexpected death. It is extremely crucial to have accurate automatic pattern recognition and data mining techniques to detect the onset of seizures and inform care-givers to help the patients. EEG signals are the preferred biosignals for diagnosis of epileptic patients. Most of the existing pattern recognition techniques used in EEG analysis leverage the notion of supervised machine learning algorithms. Since seizure data are heavily under-represented, such techniques are not always practical particularly when the labeled data is not sufficiently available or when disease progression is rapid and the corresponding EEG footprint pattern will not be robust. Furthermore, EEG pattern change is highly individual dependent and requires experienced specialists to annotate the seizure and non-seizure events. In this work, we present an unsupervised technique to discriminate seizures and non-seizures events. We employ power spectral density of EEG signals in different frequency bands that are informative features to accurately cluster seizure and non-seizure events. The experimental results tried so far indicate achieving more than 90% accuracy in clustering seizure and non-seizure events without having any prior knowledge on patient's history.

    The concept of universality proposes that dynamical systems with the same power law behaviors are equivalent at large scales. We test this hypothesis on the Earth's crust and the epileptic brain, and discover that power laws also govern the distributions of seizure energies and recurrence times. This robust correspondence is extended over seven statistics, including the direct and inverse Omori laws. We also verify in an animal seizure model the earthquake-driven hypothesis that power law statistics co-exist with characteristic scales, as coupling between constitutive elements increases towards the synchronization regime. These observations point to the universality of the dynamics of coupled threshold oscillators for systems even as diverse as Earth and brain and suggest a general strategy for forecasting seizures, one of neurosciences' grails.

    Epileptic seizures can lead to various reactions in the brain, ranging from neuronal necrosis and glial cell activation to focal structural disorganization. Furthermore, increased hippocampal neurogenesis has been documented in rodent models of acute convulsions. This is a report of hippocampal neurogenesis in a dog with spontaneous epileptic seizures. A 16-week-old epileptic German Shepherd Dog had marked neuronal cell proliferation (up to 5 mitotic figures per high-power field and increased immunohistochemical expression of proliferative cell nuclear antigen) in the dentate gyrus accompanied by microglial and astroglial activation. Some granule cells expressed doublecortin, a marker of immature neurons; mitotically active cells expressed neuronal nuclear antigen. No mitotic figures were found in the brain of age-matched control dogs. Whether increased neurogenesis represents a general reaction pattern of young epileptic dogs should be investigated.

    Energy drinks are popular among young individuals and marketed to college students, athletes, and active individuals between the ages of 21 and 35 years. We report a case that had ischemic stroke and epileptic seizure after intake of energy drink with alcohol. To the best of our knowledge, the following case is the first report of ischemic stroke after intake of energy drink. A previously healthy 37-year-old man was brought to the emergency department after a witnessed tonic-clonic seizure. According to his wife's testimony, just before loss of consciousness, the patient had been drinking 3 boxes of energy drinks (Redbull, Istanbul, Turkey, 250 mL) with vodka on an empty stomach. He did not have a history of seizures, head trauma, or family history of seizures or another disease. In cranial diffusion magnetic resonance imaging, there were hyperintense signal changes in bilateral occipital area (more pronounced in the left occipital lobe), right temporal lobe, frontal lobe, and posterior parietal lobe. All tests associated with possible etiologic causes of ischemic stroke in young patients were negative. Herein, we want to attract attention to adverse effect of energy drink usage.

    Purpose: The understanding of brain activity, and in particular events such as epileptic seizures, lies on the characterisation of the dynamics of the neural networks. The theory of non-linear dynamics provides signal analysis techniques which may give new information on the behaviour of such networks. Methods: We calculated correlation dimension maps for 19-channel EEG data from 3 patients with a total of 7 absence seizures. The signals were analysed before, during and after the seizures. Phase randomised surrogate data was used to test chaos. Results: In the seizures of two patients we could distinguish two dynamical regions on the cerebral cortex, one that seemed to exhibit chaos whereas the other seemed to exhibit noise. The pattern shown is essentially the same for seizures triggered by hyperventilation, but differ for seizures triggered by light flashes. The chaotic dynamics that one seems to observe is determined by a small number of variables and has low complexity. On the other hand, in the seizures ...

    Epileptic encephalopathies are a phenotypically and genetically heterogeneous group of severe epilepsies accompanied by intellectual disability and other neurodevelopmental features. Using next-generation sequencing, we identified four different de novo mutations in KCNA2, encoding the potassium channel KV1.2, in six isolated patients with epileptic encephalopathy (one mutation recurred three times independently). Four individuals presented with febrile and multiple afebrile, often focal seizure types, multifocal epileptiform discharges strongly activated by sleep, mild to moderate intellectual disability, delayed speech development and sometimes ataxia. Functional studies of the two mutations associated with this phenotype showed almost complete loss of function with a dominant-negative effect. Two further individuals presented with a different and more severe epileptic encephalopathy phenotype. They carried mutations inducing a drastic gain-of-function effect leading to permanently open channels. These results establish KCNA2 as a new gene involved in human neurodevelopmental disorders through two different mechanisms, predicting either hyperexcitability or electrical silencing of KV1.2-expressing neurons.

    Epileptogenesis, which occurs in an epileptic brain, is an important focus for epilepsy. The spectral analysis has been popularly applied to study the electrophysiological activities. However, the resolution is dominated by the window function of the algorithm used and the sample size. In this report, a temporal waveform analysis method is proposed to investigate the relationship of electrophysiological discharges and motor outcomes with a kindling process. Wistar rats were subjected to electrical amygdala kindling to induce temporal lobe epilepsy. During the kindling process, different morphologies of afterdischarges (ADs) were found and a recognition method, using template matching techniques combined with morphological comparators, was developed to automatically detect the epileptic patterns. The recognition results were compared to manually labeled results, and 79%-91% sensitivity was found. In addition, the initial ADs (the first 10 s) of different seizure stages were specifically utilized for recognition, and an average of 85% sensitivity was achieved. Our study provides an alternative viewpoint away from frequency analysis and time-frequency analysis to investigate epileptogenesis in an epileptic brain. The recognition method can be utilized as a preliminary inspection tool to identify remarkable changes in a patient's electrophysiological activities for clinical use. Moreover, we demonstrate the feasibility of predicting behavioral seizure stages from the early epileptiform discharges.

  4. Enhanced susceptibility to spontaneous seizures of noda epileptic rats by loss of synaptic zn(2+.

    Full Text Available Zinc homeostasis in the brain is associated with the etiology and manifestation of epileptic seizures. Adult Noda epileptic rats (NER, >12-week-old exhibit spontaneously generalized tonic-clonic convulsion about once a day. To pursue the involvement of synaptic Zn(2+ signal in susceptibility to spontaneous seizures, in the present study, the effect of zinc chelators on epileptogenesis was examined using adult NER. Clioquinol (CQ and TPEN are lipophilic zinc chelotors, transported into the brain and reduce the levels of synaptic Zn(2+. The incidence of tonic-clonic convulsion was markedly increased after i.p. injection of CQ (30-100 mg/kg and TPEN (1 mg/kg. The basal levels of extracellular Zn(2+ measured by ZnAF-2 were decreased before tonic-clonic convulsion was induced with zinc chelators. The hippocampal electroencephalograms during CQ (30 mg/kg-induced convulsions were similar to those during sound-induced convulsions in NER reported previously. Exocytosis of hippocampal mossy fibers, which was measured with FM4-64, was significantly increased in hippocampal slices from CQ-injected NER that did not show tonic-clonic convulsion yet. These results indicate that the abnormal excitability of mossy fibers is induced prior to epileptic seizures by injection of zinc chelators into NER. The incidence of tonic-clonic convulsion induced with CQ (30 mg/kg was significantly reduced by co-injection with aminooxyacetic acid (5-10 mg/kg, an anticonvulsant drug enhancing GABAergic activity, which did not affect locomotor activity. The present paper demonstrates that the abnormal excitability in the brain, especially in mossy fibers, which is potentially associated with the insufficient GABAergic neuron activity, may be a factor to reduce the threshold for epileptogenesis in NER.

    As the life expectancy of cystic fibrosis (CF) patients continues to increase, abdominal manifestations of CF are increasingly being encountered by clinicians and radiologists. Imaging plays an important role in the evaluation of adult CF patients with abdominal pain as a cause is often not discernable clinically. Accurate diagnosis is crucial in these patients as some causes may be managed conservatively, whilst others may require surgical intervention. In this review, we describe clinical presentation, imaging findings, and management of adult CF patients presenting with abdominal pain.

    2014-09-01

    Semiology, the manifestation of epilepsy, is dependent upon electrical activity produced by epileptic seizures that are organized within existing neural pathways. Clinical signs evolve as the epileptic discharge spreads in both time and space. Studying the relation between these, of which the temporal component is at least as important as the spatial one, is possible using anatomo-electro-clinical correlations of stereoelectroencephalography (SEEG) data. The period of semiology production occurs with variable time lag after seizure onset and signs then emerge more or less rapidly depending on seizure type (temporal seizures generally propagating more slowly and frontal seizures more quickly). The subset of structures involved in semiological production, the "early spread network", is tightly linked to those constituting the epileptogenic zone. The level of complexity of semiological features varies according to the degree of involvement of the primary or associative cortex, with the former having a direct relation to peripheral sensory and motor systems with production of hallucinations (visual and auditory) or elementary sensorimotor signs. Depending on propagation pattern, these signs can occur in a "march" fashion as described by Jackson. On the other hand, seizures involving the associative cortex, having a less direct relation with the peripheral nervous system, and necessarily involving more widely distributed networks manifest with altered cognitive and/or behavioral signs whose neural substrate involves a network of cortical structures, as has been observed for normal cognitive processes. Other than the anatomical localization of these structures, the frequency of the discharge is a crucial determinant of semiological effect since a fast (gamma) discharge will tend to deactivate normal function, whereas a slower theta discharge can mimic physiological function. In terms of interaction between structures, the degree of synchronization plays a key role in

    Full Text Available Myotonic dystrophy type 1 (DM1 is the commonest muscular dystrophy in adults, affecting multiple organs in addition to skeletal muscles. Cardiac conduction system abnormalities are well recognized as an important component of DM1 phenotype; however, primary structural myocardial abnormalities, which may predispose these patients to congestive heart failure, are not as well characterized. We reviewed the retrospective analysis of the clinical and echocardiographic findings in adult patients with DM1. Among 27 patients (16 male; age 19-61 years with DM1, the echocardiogram (ECHO was abnormal in 10 (37% including one of 6 patients (16% with congenital myotonic dystrophy. Reduced left ventricular ejection fraction (LVEF ≤50% was noted in 5, diastolic dysfunction in 4, left atrial dilatation in 3, left ventricular hypertrophy in 2, apical hypokinesia in 1 and mitral valve prolapse in 3 patients. One patient had paradoxical septal movement in the setting of left bundle branch block. Echocardiographic abnormalities significantly correlated with older age; however, patients with systolic dysfunction on echocardiogram ranged in age from 27 to 52 years including 2 patients aged 27 and 34 years. We can conclude that echocardiographic abnormalities are frequent in adult patients with DM1. The incidence is similar in the classical and congenital type of DM1. Overall, echocardiographic abnormalities in DM1 correlate with increasing age; however, reduced LVEF is observed even at young age. Cardiac assessment and monitoring in adult patients with DM1 should include evaluation for primary myocardial involvement.

    1984-01-01

    The article reports on the first study of the evoked activity of the brain in epileptic patients (n = 20) following sleep deprivation. An analysis of the data obtained has revealed a tendency to the shortening of the peak latent intervals of visual evoked potentials in the range of 100-200 mu sec and the V component and the interpeak interval III-V of evoked auditory trunk potentials in patients with temporal epilepsy. The phenomenon may indicate the elimination of stabilizing control involving the specific conductive pathways and, possibly, an accelerated conduction of a specific sensor signal.

There are some challenging scopes which must beconsidered for conducting the study adressing the focused question. “Which oneof the thyroid hormones is related to the AEDs consumption?”. Some studiesdemonstrated that there may be alterations in all thyroid function tests (T3, T4 andTSH after antiepileptic therapy in children (1. Some studies concluded that longtermprescription of anticonvulsive medications resulted in a decline in serum T4levels, although it had no effect on serum TSH levels. However, changes in serumT3 level was challenging and it must be investigated further (2.There were some confounding factors which may interfere with the conclusion.One of them is the type of the study.

    Full Text Available Background: Infectious diseases like neurocysticercosis and neurotuberculosis are endemic in Indian subcontinent and are important causes of epilepsy. Epileptic children are prone to have poor school performance, higher levels of anxiety and depression apart from low self esteem. These treatable condition could be easily picked up on neuroimaging like cranial computed tomography (CT scan and treated accordingly at an earliest. Objectives: To assess the role of cranial computed tomography scan in children having epilepsy. Material and Methods: Seventy two children between the age of 1 month and 14 years were prospectively enrolled, who had atleast two unprovoked seizures greater than 24 hours apart, and all those children where seizures result from acute central nervous system insult were meticulously excluded. Diagnosis of epilepsy was based on detailed history, thorough clinical examination, routine laboratory tests with additional specific tests like electroencephalogram (EEG and CT scan brain. Results: Males constituted 62.5% and females 37.5% of our sample (p=0.247. The EEG was abnormal in 68.1% of all subjects, among which EEG was abnormal in 69.8% of generalized seizures, 64.7% in partial seizures and 1% in undetermined seizures. The spectrum of various seizure types in our study was generalized seizures in 73.6%, partial seizures in 23.6% & undetermined seizures in 2.8%. The incidence of these lesions in hospitalized young epileptics was 31.9%, in order of their frequency, it was cerebral atrophy and dilated ventricle (18.8% each; calcifications (15.5%; encephalomalacia and pachygyria (9.4% each; HIE changes, tuberous sclerosis (6.3% each; leucodystrophy, thin corpus callosum, large cisterna magna, granuloma and periventricular leukomalacia (3.1% each.

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

    AIM: To establish a culture system of marrow mesenchymal stem cells (MSCs) from hepatitis B patients and normal adults and to compare their biological characteristics.METHODS: MSCs were isolated from bone marrow in 34 male hepatitis B patients and 15 male normal adults and cultivated in vitro. Their biological characteristics including surface markers, shapes and appearances, growth curves, first passage time and passage generations were compared.RESULTS: Cultivation achievement ratio of hepatitis B patients was lower than that of normal adults, no statistical significance (82.35% vs 100%, P >0.05). Compared with MSCs of normal adults, MSCs of hepatitis B patients presented a statistical lower growth curve, longer first passage time (13.0 ± 1.6 d vs 11.4 ± 1.5 d, P < 0.05), fewer passaging generation numbers (10.5 ± 1.4 generations vs 12.3±1.7 generations, P < 0.05), though both shared same appearances, shapes and surface markers. MSCs in hepatitis B patients would expand, spread out and age more easily and there were more refractive particles in the cytoplasm.CONCLUSION: MSCs from hepatitis B patients can be cultured in vitro. Although their appearance, shape and surface marker are similar to those of MSCs from normal adults, there are differences in their biological characteristics.

    Full Text Available Functional neuroimaging studies of epilepsy patients often show, at the time of epileptic activity, deactivation in default mode network (DMN regions, which is hypothesized to reflect altered consciousness. We aimed to study the metabolic and electrophysiological correlates of these changes in the DMN regions. We studied six epilepsy patients that underwent scalp EEG-fMRI and later stereotaxic intracerebral EEG (SEEG sampling regions of DMN (posterior cingulate cortex, Pre-cuneus, inferior parietal lobule, medial prefrontal cortex and dorsolateral frontal cortex as well as non-DMN regions. SEEG recordings were subject to frequency analyses comparing sections with interictal epileptic discharges (IED to IED-free baselines in the IED-generating region, DMN and non-DMN regions. EEG-fMRI and SEEG were obtained at rest. During IEDs, EEG-fMRI demonstrated deactivation in various DMN nodes in 5 of 6 patients, most frequently the pre-cuneus and inferior parietal lobule, and less frequently the other DMN nodes. SEEG analyses demonstrated decrease in gamma power (50-150 Hz, and increase in the power of lower frequencies (<30 Hz at times of IEDs, in at least one DMN node in all patients. These changes were not apparent in the non-DMN regions. We demonstrate that, at the time of IEDs, DMN regions decrease their metabolic demand and undergo an EEG change consisting of decreased gamma and increased lower frequencies. These findings, specific to DMN regions, confirm in a pathological condition a direct relationship between DMN BOLD activity and EEG activity. They indicate that epileptic activity affects the DMN, and therefore may momentarily reduce the consciousness level and cognitive reserve.

    Full Text Available Previous reports have suggested that the incidence of some neoplastic disorders, particularly malignant lymphoma, is increased in patients with celiac disease. In this study, the type and number of neoplastic disorders detected in 100 consecutive celiac disease patients were explored. Sixty-five patients were initially diagnosed with celiac disease before, and 35 after, age 60 years. Ten elderly celiac patients had lymphoma or small intestinal adenocarcinoma. Although the overall incidence of malignant lymphoma was 8%, similar to that in other centres, the incidence in elderly celiac patients was 23% in this study. Celiac disease was detected before or after the diagnosis of lymphoma or small intestinal adenocarcinoma. In some patients, epithelial lymphocytosis was evident in the gastric, colonic or biliary tract epithelium. In addition, other immune-mediated disorders, dermatitis herpetiformis and autoimmune thyroiditis, were common. Finally, other malignant disorders of the esophagus, stomach and colon were not detected.

    Pallister-Killian syndrome is a rare syndrome of multiple congenital anomalies attributable to the presence of a mosaic supernumerary isochromosome (12p). Although the clinical manifestations of Pallister-Killian syndrome are variable, the most common anomalies include craniofacial dysmorphisms, limb deformities, progressive psychomotor development delay, severe hypotonia, and epilepsy. Standard karyotype is nearly always normal, but the isochromosome (12p) is present in a high percentage of skin fibroblasts. In this article, we report the case of 2 boys with Pallister-Killian syndrome having late-onset, drug-resistant epileptic spasms. Seizures have been reported in 40% of patients with Pallister-Killian syndrome but are poorly described. Epileptic spasms are not unusual in patients with brain malformations, chromosomal aberrations, and genetic syndromes, but epileptic spasms could be easily mistaken for behavioral manifestations. A better electroclinical characterization of epileptic seizures in Pallister-Killian syndrome using appropriate polygraphic tests (video-electroencephalography, electromyography) may lead to an early diagnosis and specific treatment for this form of epileptic spasms caused by this rare syndrome.

    Objective. Automated behavioral state classification can benefit next generation implantable epilepsy devices. In this study we explored the feasibility of automated awake (AW) and slow wave sleep (SWS) classification using wide bandwidth intracranial EEG (iEEG) in patients undergoing evaluation for epilepsy surgery. Approach. Data from seven patients (age 34+/- 12 , 4 women) who underwent intracranial depth electrode implantation for iEEG monitoring were included. Spectral power features (0.1–600 Hz) spanning several frequency bands from a single electrode were used to train and test a support vector machine classifier. Main results. Classification accuracy of 97.8  ±  0.3% (normal tissue) and 89.4  ±  0.8% (epileptic tissue) across seven subjects using multiple spectral power features from a single electrode was achieved. Spectral power features from electrodes placed in normal temporal neocortex were found to be more useful (accuracy 90.8  ±  0.8%) for sleep-wake state classification than electrodes located in normal hippocampus (87.1  ±  1.6%). Spectral power in high frequency band features (Ripple (80–250 Hz), Fast Ripple (250–600 Hz)) showed comparable performance for AW and SWS classification as the best performing Berger bands (Alpha, Beta, low Gamma) with accuracy  ⩾90% using a single electrode contact and single spectral feature. Significance. Automated classification of wake and SWS should prove useful for future implantable epilepsy devices with limited computational power, memory, and number of electrodes. Applications include quantifying patient sleep patterns and behavioral state dependent detection, prediction, and electrical stimulation therapies.

    ,balance and justice. Since some epileptic patients lack in the knowledge of epilepsy and proper treatment and suffer from discrimination in the health care, more untreated and non-proper treatment, doctors and nursing persons should take the attitude of being beneficial to the patients. Medication for the epileptics, especially the female patients at the first period of pregnancy, the incidence of the deformed children was high. Should the principle of beneficence be applied to mothers or children? The number of the operative treatment was more and more in patients with epilepsy, while surgery itself is a risk behavior .If there is no better method to choose, and all the available choices have their advantage and disadvantages. Physicians can only choose the better one from the two kinds of harm, trying to make the patientssuffer the least harm with the largest effect. Aggressive behaviors can be observed during seizure or unconsciousness state. Controlling the moving range of the patients with epilepsy consciously is in accord with the general ethical behavior, on the contrary, confinement disobeys the morals and the curative effect is not good. The extreme behavior of the patients with epilepsy is suicide and occurred more in unemployed, unmarried and living alone, male, and patients with mental disorders in epilepsy. The direct reasons of suicide are unemployment, low social status, and little understanding and care from their communities, families and friends.The sensible ethical principle for epileptics is to treat the patients as normal people in the society.CONCLUSION: Epileptic crowd need care from the society, family and other factors. Proper considering ethical principle in treating the population is the humane solicitude and to help the patients regain health and improve the life quality.

    Background Although most patients with tetralogy of Fallot undergo radical repair during infancy and childhood,patients that remain undiagnosed and untreated until adulthood can still be treated.This study aimed to evaluate longterm outcomes of adult patients with tetralogy of Fallot who were treated surgically,and to determine the predictors of postoperative pulmonary regurgitation.Methods Fifty-six adult patients underwent complete surgical repair.Forty-three patients (76.8%) required a transannular patch.Systolic,diastolic,and mean pressure in the main pulmonary artery were measured after repair.Results The early mortality rate was 3.6%.The 16-year survival rate was (84.4±11.5)%.Late echocardiography revealed 41 patients with transannular patch who had pulmonary regurgitation,consisting of mild pulmonary regurgitation in 28 patients,moderate in eight,and severe regurgitation in five patients.In addition,there was right ventricular outflow tract stenosis in nine patients,moderate/severe tricuspid valve regurgitation in seven,and residual ventricular septal defect in five.Logistic regression analysis demonstrated that the mean pulmonary pressure measured just after repair predicted late pulmonary regurgitation.Conclusions The long-term survival of surgically treated adult patients with tetralogy of Fallot is acceptable.The mean pressure >20 mmHg in the main pulmonary artery measured right after surgical repair may be a feasible reference to time the reconstruction of the pulmonary valve.

    Full Text Available Lichen striatus is a self-limited lichenoid eruption that follows Blaschko’s lines. It is particularly common in children and rarely seen in adults. Cases related to atopic diathesis are common, besides it is reported among family members. Viral infections, vaccines and trauma related cases are also present. Various environmental stimuli in the setting of genetic predisposition may play a role. We herein, reported a forty eight year-old woman who developed lichen striatus eruptions in her arm and trunk while she was receiving UVB treatment with maintenance dose for psoriasis. Phototherapy might act as a stimulant with its immunosuppressive and traumatic effects.

    Adult attention deficit/hyperactivity disorder (ADHD) and borderline personality disorder (BPD) share several clinical features, e.g. emotional lability and impulsivity. This study aimed to delineate differences and similarities between ADHD and BPD with respect to borderline typical symptomatology and gender specifics. Borderline symptomatology was assessed in 60 adult patients with ADHD with the borderline symptom list (BSL) and compared to both 60 gender- and age-matched BPD patients and control subjects. The BSL is a standardized instrument including 95 items on 7 subscales (self-perception, affect regulation, self-destruction, dysphoria, loneliness, intrusions and hostility). Adult ADHD patients showed significantly higher BSL total scores and all of the seven subscales compared to healthy controls (p ADHD and BPD patients were found with respect to self-destruction (d = 1.12) and affect dysregulation (d = 0.90), whereas the smallest difference was found with respect to loneliness (d = 0.36). In females, the BSL subscales "loneliness" and "hostility" did not differentiate between BPD and ADHD. Borderline typical symptoms are common in adult patients with ADHD but seem to be less pronounced than in patients with BPD. Females with ADHD and BPD share more clinical features than males. However, symptoms of self-destruction and affect dysregulation appear to be more severe in BPD patients.

    Full Text Available There were treated 48 patients (adolescents and adults with severe congenital clubfoot in Saratov Research Institute of Traumatology and Orthopedics. 43 patients had the age ranged from 16 to 30, 5 patients had the age over 30. 19 patients had bilateral clubfoot, 29 patients had unilateral clubfoot including 19 on right side and 10 left side. To improve treatment results and to prevent deformity recurrence we developed two-staged surgery for congenital clubfoot treatment in adults. Cartilages of talo-navicular, talo-calcanean, cuneo-talar joints are deleted and deformity is corrected with external fixator on I stage. Surgeon performs external fixator resetting, autobone grafting of these joints with compressive arthrodesis on second stage. This method results in full foot reconstruction, good functional outcome, full weight-bearing and improves patient life’s quality.

    Isolated left ventricular noncompaction in adults is uncommon. The most frequent clinical manifestations are heart failure due to left ventricular systolic dysfunction and supraventricular and ventricular arrhythmias, which may be sustained and associated with sudden death. Thromboembolic complications are also possible. We report the case of an adult patient with isolated left ventricular noncompaction who came to our observation because of acute cerebral ischemia, an initial presentation of the disease only rarely described.

    Full Text Available Cystic fibrosis patients with an implantable venous access device (IVAD and a patent foramen ovale (PFO are at an increased risk of developing paradoxical embolism. A 33-year-old patient who had a cerebrovascular accident in the above setting is described. She had been anticoagulated because she had thrombosis of the tip of the indwelling catheter, and her PFO was closed percutaneuosly followed by replacement of her IVAD. She made a full neurological recovery. Echocardiography and prophylactic closure of the PFO, when present, as primary prevention for paradoxical embolism may be warranted in cystic fibrosis patients before placement of an IVAD.

    Patient survival after cardiac arrest can be improved significantly with prompt and effective resuscitative care. This systematic review analyzes the basic life support factors that improve survival outcome, including chest compression technique and rapid defibrillation of shockable rhythms. For patients who are successfully resuscitated, comprehensive postresuscitation care is essential. Targeted temperature management is recommended for all patients who remain comatose, in addition to careful monitoring of oxygenation, hemodynamics, and cardiac rhythm. Management of cardiac arrest in circumstances such as pregnancy, pulmonary embolism, opioid overdose and other toxicologic causes, hypothermia, and coronary ischemia are also reviewed.

    Vigabatrin (Sabril®), approved in the US in 2009, is currently indicated as adjunctive therapy for refractory complex partial seizures (rCPS) in patients ≥ 10 years old who have responded inadequately to several alternative treatments and as monotherapy for infantile spasms (IS) in patients 1 month to 2 years of age. Because of reports of vision loss following vigabatrin exposure, FDA approval required a risk evaluation mitigation strategy (REMS) program. Vigabatrin is only available in the US through Support, Help, And Resources for Epilepsy (SHARE), which includes a mandated registry. This article describes 5 years of demographic and treatment exposure data from adult patients (≥ 17 years old) in the US treated with vigabatrin and monitored in the ongoing Sabril® registry. Registry participation is mandatory for all US Sabril® prescribers and patients. A benefit-risk assessment must be documented by the physician for a patient to progress to maintenance therapy, defined as 1 month of vigabatrin treatment for patients with IS and 3 months for patients with rCPS. Ophthalmologic assessments must be documented during and after completion of therapy. As of August 26, 2014, a total of 6823 patients were enrolled in the registry, of which 1200 were adults at enrollment. Of these patients, 1031 (86%) were naïve to vigabatrin. The majority of adult patients (n=783, 65%) had previously been prescribed ≥ 4 AEDs, and 719 (60%) were receiving ≥ 3 concomitant AEDs at vigabatrin initiation. Prescribers submitted an initial ophthalmological assessment form for 863 patients; an ophthalmologic exam was not completed for 300 (35%) patients and thus, were considered exempted from vision testing. Of these patients, 128 (43%) were exempted for neurologic disabilities. Clinicians discontinued treatment in 8 patients because of visual field deficits (VFD) (5 patients naïve to vigabatrin and 3 patients previously exposed). Based on Kaplan-Meier survival estimates, it is

    Poly(A+) RNA was extracted from the temporal lobe (TL) of medically intractable epileptic patients which underwent surgical TL resection. Injection of this mRNA into Xenopus oocytes led to the expression of ionotropic receptors for γ-aminobutyric acid (GABA), kainate (KAI) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA). Membrane currents elicited by GABA inverted polarity at −15 mV, close to the oocyte's chloride equilibrium potential, were inhibited by bicuculline, and were potentiated by pentobarbital and flunitrazepam. These basic characteristics were also displayed by GABA currents elicited in oocytes injected with mRNAs isolated from human TL glioma (TLG) or from mouse TL. However, the GABA receptors expressed by the epileptic TL mRNA exhibited some unusual properties, consisting in a rapid current run-down after repetitive GABA applications and a large EC50 (125 μM). AMPA alone evoked very small or nil currents, whereas KAI induced larger currents. Nevertheless, upon cyclothiazide treatment, AMPA elicited substantial currents that, like the KAI currents, were inhibited by 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX). Furthermore, the glutamate receptor 5 (GluR5) agonist, ATPA, failed to evoke an obvious current although both RT-PCR and Western blot analyses showed GluR5 expression in the epileptic TL. Oocytes injected with mouse TL or human TLG mRNAs generated KAI and AMPA currents similar to those evoked in oocytes injected with epileptic TL mRNA but, in contrast to these, the mouse TL and human TLG oocytes were also responsive to ATPA. Our findings are in accord with the concept that both a depression of GABA inhibition and a dysfunction of the KAI-receptor system maintain a high neuronal excitability that results in epileptic seizures.

    Full Text Available Congenital H-type tracheoesophageal fistula (TEF in adults is a rare presentation and can test the diagnostic acumen of a surgeon, endoscopist, and the radiologist. These undetected fistulas may present as chronic lung disease of unknown origin because repeated aspirations can lead to recurrent lung infections and bronchiectasis. Congenital TEFs should be considered in the diagnosis of infants and young adults with recurrent respiratory distress and/or infections. Here, we present the successful management of this rare case in an adult patient.

    Giardia duodenalis is considered the most common intestinal parasite in humans worldwide. Children are especially affected, with more severe consequences than adults. The present study was designed to determine the distribution of assemblages A and B Giardia infection in children and adults, with the use of light microscopy and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) as diagnostic procedures, and to investigate its associations with clinical and epidemiological data collected from children and adult groups. This cross-sectional study was conducted from October 2012 to October 2013 by collecting fecal samples from 200 children and 200 adults complaining of diarrhea. Samples were subjected to parasitological examination by direct wet smear and formol-ether methods. Genotyping of G. doudenalis samples was conducted by PCR-RFLP analysis. Giardia duodenalis infection caused by assemblages A and B was identified in 60 samples, 34 from children and 26 from adults. Assemblage B was detected in 38 patients (63.34%), and assemblage A was detected in 22 patients (36.66%). Assemblage A was significantly more frequent in children with age range 2-8 yr, and assemblage B was higher in children with age range 6-16 yr old. Diarrhea frequency/day and recurrences per month affected patients infected with assemblage A (P value Giardia assemblages A and B were identified in children and adults, assemblage A infected younger children more frequently and was more closely related to severe clinical manifestations than assemblage B.

    Work in the field of culturally competent medical care draws on studies showing that minority Americans often report lower satisfaction with care than White Americans and recommends that providers should adapt care to patients' cultural needs. However, empirical evidence in support of cultural competence models is limited by reliance upon measurements of racial rather than ethnic identity and also by a near-total neglect of American Indians. This project explored the relationship between ethnic identity and satisfaction using survey data collected from 115 chronically ill American Indian patients >or=50 years at a Cherokee Nation clinic. Satisfaction scores were high overall and comparable to those found in the general population. Nevertheless, analysis using hierarchical linear modeling showed that patients' self-rated American Indian ethnic identity was significantly associated with satisfaction. Specifically, patients who rated themselves high on the measure of American Indian ethnic identity reported reduced scores on satisfaction with health care providers' social skill and attentiveness, as compared to those who rated themselves lower. Significant associations remained after controlling for patients' sex, age, education, marital status, self-reported health, wait time, and number of previous visits. There were no significant associations between patients' American Indian ethnic identity and satisfaction with provider's technical skill and shared decision-making. Likewise, there were no significant associations between satisfaction and a separate measure of White American ethnic identity, although a suggestive trend was observed for satisfaction with provider's social skill. Our findings demonstrate the importance of including measures of ethnic identity in studies of medical satisfaction in racial minority populations. They support the importance of adapting care to patient's cultural needs, and they highlight the particular significance of interpersonal

    First experience in the occupational rehabilitation of a group of less gifted juvenile epileptics is reported. In this paper, the emphasis is on both psychological and sociopsychological aspects of rehabilitation. The observation and control of processes and reactions is of major importance to the entire program of rehabilitation. Also, the improvement of the occupational situation of a patient will have a positive influence on his social behavior, self-confidence, and emotions. Rehabilitation is a complex process, with the results depending to a very large extent on extremely methodical approaches.

    Due to improving results in congenital heart surgery, the number of adult patients with congenital heart defect is increasing. The question is: what kind of problems can be managed in this patient-group? The authors review the different problems of management of congenital heart defects in adults based on national and international literature data. Simple defects recognised in adults, postoperative residual problems, changing of small grafts and valves, correction of primary or operated coarctation aortae can be usually managed without problems. A very close follow-up is necessary to establish the correct period for heart transplantation in patients with transposition of great arteries with Senning/Mustard operation, and univentricular heart corrected with "Fontan-circulation" type surgical procedure. The authors conclude that although the number of patients increases, only a few congenital heart diseases may cause problems. It seems important (1) to monitor asymptomatic patient who underwent operation (Fallot-IV, Ross procedure, etc.), (2) follow up regularly patients who underwent Senning/Mustard procedure (magnetic resonance imaging, echocardiography, brain natriuretic peptide measurement), (3) define the proper period of preparation for heart transplantation of patients with a univentricular heart, with special attention to the possibility of multiorgan (lung, liver, etc.) failure. Due to the improvement of foetal diagnosis of congenital heart defects, the number of patients with complex congenital heart defects is decreasing. The standard management of these patients could be primary heart transplantation in infancy.

    The fear that patients with high-mathematical model for end stage liver disease (MELD) score may not be suitable candidates for segmental grafts because of their need for greater liver mass has continued to push the transplant community toward the use of whole LT (WLT) in preference to split LT (SLT). In order to define the outcome of segmental liver transplantation in a better manner in high-MELD patients (score > or =26), we queried the UNOS registry for graft and patient survival results according to MELD score in adult patients receiving WLT and SLT in the United States from the inception of MELD allocation (February 27, 2002) through March 9, 2007. A total of 316 adult patients received a SLT as compared with 20 778 WLTs. Patient and graft survival rates at 6 and 12 months were comparable for all MELD ranges, including the 'high-MELD' recipients (e.g. at MELD score 31-35, patients' and grafts' survival rates at 12 months was 87.5% in SLT group vs. 84.4% and 76.7% in WLT group respectively). The results even at higher MELD scores (i.e. >35) were more than acceptable. In conclusion, patient and graft survival rates for SLT in high-MELD adult patients are comparable to the same for WLT.

    Whether the powerful medications used to treat epilepsy increase the risk of cancer has been debated for decades, but until now no study could disentangle the contributions of anti-epileptic medications and epilepsy itself to cancer risk. Using a cohort comprising all Danish residents ≥ 16 years...... old at some point during the period 1996-2010 (>56 million person-years of follow-up) and information from national health registers, we examined associations between anti-epileptic medication use and cancer rates in persons with and without epilepsy, and between epilepsy and cancer rates in treated...... and untreated individuals. Associations were expressed as incidence rate ratios (IRRs) estimated using Poisson regression. Among persons without epilepsy, use of anti-epileptic medication increased the rates of most cancers little or not at all, although we observed moderately increased rates of liver, mouth...

    This article reviews and summarizes the literature on patient safety issues in the rehabilitation of adults with an amputation. Safety issues in the following areas are discussed; the prosthesis, falls, wound care, pain, and treatment of complex patients. Specific recommendations for further research and implementation strategies to prevent injury and improve safety are also provided. Communication between interdisciplinary team members and patient and caregiver education are crucial to executing a safe treatment plan. The multidisciplinary rehabilitation team members should feel comfortable discussing safety issues with patients and be able to recommend preventive approaches to patients as appropriate.

    The human brain is a delicate mix of neurons (brain cells), electrical impulses and chemicals, known as neurotransmitters. Any damage has the potential to disrupt the workings of the brain and cause seizures. These epileptic seizures are the manifestations of epilepsy. The electroencephalograph (EEG) signals register average neuronal activity from the cerebral cortex and label changes in activity over large areas. A detailed analysis of these electroencephalograph (EEG) signals provides valuable insights into the mechanisms instigating epileptic disorders. Moreover, the detection of interictal spikes and epileptic seizures in an EEG signal plays an important role in the diagnosis of epilepsy. Automatic seizure detection methods are required, as these epileptic seizures are volatile and unpredictable. This paper deals with an automated detection of epileptic seizures in EEG signals using empirical mode decomposition (EMD) for feature extraction and proposes a novel genetic programming (GP) approach for classifying the EEG signals. Improvements in the standard GP approach are made using a Constructive Genetic Programming (CGP) in which constructive crossover and constructive subtree mutation operators are introduced. A hill climbing search is integrated in crossover and mutation operators to remove the destructive nature of these operators. A new concept of selecting the Globally Prime offspring is also presented to select the best fitness offspring generated during crossover. To decrease the time complexity of GP, a new dynamic fitness value computation (DFVC) is employed to increase the computational speed. We conducted five different sets of experiments to evaluate the performance of the proposed model in the classification of different mixtures of normal, interictal and ictal signals, and the accuracies achieved are outstandingly high. The experimental results are compared with the existing methods on same datasets, and these results affirm the potential use of

    OBJECTIVE. To compare the symptoms of delirium as assessed by the Delirium Rating Scale-Revised-98 (DRS-R-98) and associated aetiologies in adult and elderly patients seen in a consultation-liaison service. METHODS. A total of 321 consecutive patients with a DSM-IV-TR diagnosis of delirium were assessed on the DRS-R-98 and a study-specific aetiology checklist. RESULTS. Of the 321 patients, 245 (76%) aged 18 to 64 years formed the adult group, while 76 (24%) formed the elderly group (≥ 65 years). The prevalence and severity of various symptoms of delirium as assessed using the DRS-R-98 were similar across the 2 groups, except for the adult group having statistically higher prevalence and severity scores for thought process abnormalities and lability of affect. For both groups and the whole sample, factor analysis yielded a 3-factor model for the phenomenology. In the 2 groups, the DRS-R-98 item loadings showed subtle differences across various factors. The 2 groups were similar for the mean number of aetiologies associated with delirium, the mean number being 3. However, the 2 groups differed with respect to hepatic derangement, substance intoxication, withdrawal, and postpartum causes being more common in the adult group, in contrast lung disease and cardiac abnormalities were more common in the elderly group. CONCLUSION. Adult and elderly patients with delirium are similar with respect to the distribution of various symptoms, motor subtypes, and associated aetiologies.

    Focal epileptic lesions were made in rats by systemic focal epileptogenesis. In this method, a focal lesion of the blood-brain barrier (BBB) is produced by focal alpha irradiation followed by repeated systemic injection of a convulsant drug that cannot cross the normal BBB, resulting in a chronic epileptic focus. Changes in the spike frequency of these foci in response to various drugs was recorded. The controls, saline and chlorpromazine, produced no change. Phenytoin, phenobarbital, chlordiazepoxide, and valproic acid produced the expected decrease in spike frequency. Pentobarbital and diazepam produced a paradoxical increase in spike frequency.

    This prospective study examined the adult patient's perception of recovery after insertion of three types of orthodontic appliances: Buccal, Lingual and Invisalign. The sample consisted of sixty-eight adult patients (45 females and 23 males) who comprised three groups: 28 Buccal, 19 Lingual, and 21 Invisalign patients. After appliance insertion, patients completed a Health-Related Quality of Life questionnaire daily for the first week and again on day 14, in order to assess patients' perception of pain and analgesic consumption. In addition, four areas of dysfunction were assessed: oral dysfunction, eating disturbances, general activity parameters, and oral symptoms. Lingual appliance was associated with more severe pain and analgesic consumption, the greatest oral and general dysfunction, and the most difficult and longest recovery. The Invisalign patients complained of relatively high levels of pain in the first days after insertion; however this group was characterized by the lowest level of oral symptoms and by a similar level of general activity disturbances and oral dysfunction compared to the Buccal appliance. Many Lingual and some Buccal patients did not reach a full recovery from their eating difficulties by the end of the study period. The present study provides information to adult patients and clinicians assisting them in choosing the most appropriate treatment modality in relation to Health-Related Quality of Life parameters.

    Primary cheiloplasty in adult patients with unrepaired complete bilateral cleft lip and palate is quite challenging due to severe premaxillary anterior projection. To get the best repair results, the author carried out repositioning of the premaxilla and repair of the lip deformity in a single stage. Positive results for the primary lip repair and appropriate repositioning of the premaxilla were achieved. No avascular necrosis of the premaxilla was observed. Repositioning of the premaxilla and repair of the lip deformity in a single operation appears to be a reliable method for treating adult patients with previously unrepaired or poorly repaired bilateral cleft lip and palate.

    Graph theory provides a useful framework to study functional brain networks from neuroimaging data. In epilepsy research, recent findings suggest that it offers unique insight into the fingerprints of this pathology on brain dynamics. Most studies hitherto have focused on seizure activity during focal epilepsy, but less is known about functional epileptic brain networks during interictal activity in frontal focal and generalized epilepsy. Besides, it is not clear yet which measures are most suitable to characterize these networks. To address these issues, we recorded magnetoencephalographic (MEG) data using two orthogonal planar gradiometers from 45 subjects from three groups (15 healthy controls (7 males, 24 ± 6 years), 15 frontal focal (8 male, 32 ± 16 years) and 15 generalized epileptic (6 male, 27 ± 7 years) patients) during interictal resting state with closed eyes. Then, we estimated the total and relative spectral power of the largest principal component of the gradiometers, and the degree of phase synchronization between each sensor site in the frequency range [0.5-40 Hz]. We further calculated a comprehensive battery of 15 graph-theoretic measures and used the affinity propagation clustering algorithm to elucidate the minimum set of them that fully describe these functional brain networks. The results show that differences in spectral power between the control and the other two groups have a distinctive pattern: generalized epilepsy presents higher total power for all frequencies except the alpha band over a widespread set of sensors; frontal focal epilepsy shows higher relative power in the beta band bilaterally in the fronto-central sensors. Moreover, all network indices can be clustered into three groups, whose exemplars are the global network efficiency, the eccentricity and the synchronizability. Again, the patterns of differences were clear: the brain network of the generalized epilepsy patients presented greater efficiency and lower

    Corticosteroid therapy as adjunctive treatment in community-acquired pneumonia (CAP) is a promising but controversial subject. The potentially beneficial effect of corticosteroids is based on the ability of steroids to dampen an excessive inflammatory response that often occurs in patients with CAP. This excessive inflammatory response can cause damage to the lungs and other organs, and is associated with poor outcome.

    Malnutrition of critically ill patients is a widespread phenomenon in intensive care units (ICUs) worldwide. Lipid emulsions (LEs) are able to provide sufficient caloric support and essential fatty acids to correct the energy deficit and improve outcome. Furthermore, components of LEs might impact cell and organ function in an ICU setting. All currently available LEs for parenteral use are effective in providing energy and possess a good safety profile. Nevertheless, soybean oil-based LEs have been associated with an elevated risk of adverse outcomes, possibly due to their high content of omega-6 fatty acids. More newly developed emulsions partially replace soybean oil with medium-chain triglycerides, fish oil or olive oil in various combinations to reduce its negative effects on immune function and inflammation. The majority of experimental studies and smaller clinical trials provide initial evidence for a beneficial impact of these modern LEs on critically ill patients. However, large, well-designed clinical trials are needed to evaluate which LE offers the greatest advantages concerning clinical outcome. Lipid emulsions (LEs) are a powerful source of energy that can help to adjust the caloric deficit of intensive care unit (ICU) patients. LEs possess various biological activities, but their subsequent impact on critically ill patients awaits further investigations.

    The objective of this study is to compare the effectiveness among sulpiride, risperidone, olanzapine, and haloperidol by evaluating the persistence of drug use. A retrospective cohort study was conducted by analyzing the National Health Insurance Research Database of Taiwan. Patients with schizophrenia aged 18-65 years and newly prescribed with a single oral antipsychotic medication between years 2003 and 2008 were included. The primary outcome was the persistence of antipsychotic agents by calculating the treatment duration till treatment changed. All defined treatment changes were also analyzed separately, including discontinuation, switching, augmentation, and hospitalization. A total of 1324 eligible patients were included, with an average age of 36 years old and approximately 45% of them were female. The most prevalent antipsychotic use was risperidone (42.1%), followed by sulpiride (36.0%), haloperidol (14.2%), and olanzapine (7.7%). After adjusting for patient demographics, mental illness characteristics, and propensity score, the Cox regression models found that the risk of nonpersistence was significantly higher in patients receiving risperidone (hazard ratio [HR], 1.22; 95% CI, 1.06-1.40), haloperidol (HR, 1.98; 95% CI, 1.63-2.40), and olanzapine (HR, 1.34; 95% CI, 1.07-1.68), as compared with sulpiride, suggesting the effectiveness of sulpiride was better than the other 3 antipsychotics. Therefore, this study would provide strong grounds for a properly conducted randomized controlled trial of the clinical- and cost-effectiveness of sulpiride vs atypical antipsychotics.

  5. Analgesia for terminally ill adult patients. Preserve quality of life.

    2011-11-01

    Adequate pain management is crucial in maintaining the best possible quality of life for terminally ill patients. This article examines pain management in the palliative care setting, based on a review of the literature using the standard Prescrire methodology. Accurate pain evaluation, preferably by the patient, is essential for guiding treatment decisions. Some causes of pain are amenable to specific treatments. The expected benefits and harms of the various treatment options and procedures must be weighed on a case by case basis. Quality of life should always be the first priority. The World Health Organization has developed a "three-step analgesic ladder", based on the use of increasingly potent analgesics: step I analgesics include paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs); codeine is the standard step II analgesic; and morphine is the standard step III analgesic. Fentanyl is an alternative to morphine. The daily morphine dose must be determined for each patient. Morphine titration starts with oral doses given every 4 hours, but additional doses can be taken every hour if necessary. Total consumption is then used to calculate the dose required the following day. A sustained-release product can be used to reduce the number of doses required when a consistently effective daily dose has been established. When patients are unable to take morphine orally, it can be given by subcutaneous injection, and by subcutaneous or intravenous infusion. Pumps allow the patient to self-administer morphine on demand. Fentanyl transdermal patches are another option for stable pain. Immediate-release oral forms and injections are useful for preventing or treating breakthrough pain. If morphine requirements increase during treatment, the most likely explanations are exacerbations of pain or an excessively long interval between doses. Pharmacological tolerance and psychological dependence are rare during palliative care. In case of renal failure, the morphine

    2016-02-01

    Full Text Available Ecstatic epileptic seizures are a rare but compelling epileptic entity. During the first seconds of these seizures, ecstatic auras provoke feelings of well-being, intense serenity, bliss, and enhanced self-awareness. They are associated with the impression of time dilation, and can be described as a mystic experience by some patients. The functional neuroanatomy of ecstatic seizures is still debated. During recent years several patients presenting with ecstatic auras have been reported by others and us (in total n=49; a few of them in the setting of presurgical evaluation including electrical brain stimulation. According to the recently recognized functions of the insula, and the results of nuclear brain imaging and electrical stimulation, the ecstatic symptoms in these patients seem to localize to a functional network centered around the anterior insular cortex, where we thus propose to locate this rare ictal phenomenon. Here we summarize the role of the multiple sensory, autonomic, affective and cognitive functions of the insular cortex, which are integrated into the creation of self-awareness, and we suggest how this system may become dysfunctional on several levels during ecstatic aura.

    Magnetoencephalography (MEG) is a novel noninvasive technique for localizing epileptic zones. Tuberous sclerosis complex (TSC) is often associated with medically refractory epilepsy with multiple epileptic zones. Surgical treatment of TSC requires accurate localization of epileptogenic tubers. The objective of this study was to introduce a new MEG technique, synthetic aperture magnetometry (SAM), to volumetrically localize irritable zones and clarify the correlations between SAM, dipole modeling and anatomical tubers. Eight pediatric patients with TSC confirmed by clinical and neuroimaging findings were retrospectively studied. MEG data were recorded using a whole-cortex CTF OMEGA system. Sleep deprivation was employed to provoke epileptiform activity. Irritable zones were localized using both dipole modeling and SAM. MRI detected 42 tubers in the eight patients. Dipole modeling localized 28 irritable zones, and 19 out of the 28 zones were near tubers (19/42, 45%). SAM found 51 irritable zones, and 31 out of the 51 zones were near tubers (31/42, 74%). Among the 51 irritable zones determined by SAM, thirty-five zones were in 1-35 Hz, nine zones were in 35-60 Hz, and seven zones were in 60-120 Hz. The new method, SAM, yielded very plausible equivalent sources for patients who showed anatomical tubers on MRI. Compared to conventional dipole modeling, SAM appeared to offer increased detection of irritable zones and beneficial volumetric and frequency descriptions. (orig.)

  10. Extending the use of stiripentol to other epileptic syndromes: a case of PCDH19-related epilepsy.

    2015-03-01

    Stiripentol is an antiepileptic drug (AED) approved by the European Medicines Agency for the treatment of Dravet Syndrome (DS) as adjunct treatment with valproate and clobazam. PCDH19-related epilepsy is an emerging epileptic syndrome characterized by the occurrence of epilepsy in female patients associated with mental retardation and autistic features in most cases. It shares many features with DS: age of onset, normal development before the onset, fever sensitivity, cognitive impairment during the time, drug-resistance. Basing on the numerous similarities between DS and PCDH19-related epilepsy, we tried stiripentol in a nine and half year old female patient with PCDH19-related resistant epilepsy, as add-on treatment to valproate and clobazam. It had a surprising efficacy as the patient had a two years and ten months seizure free period, as never in her epilepsy history. Up to date, clinical trials of stiripentol have been always focused on DS. The delineation of new epileptic syndromes, as PCDH19-related epilepsy, opens new scenarios to the utilization of this AED. This case report is suggestive of a good response of PCDH19-related Epilepsy to stiripentol. However further cases and above all clinical trials are necessary to confirm this result.

  11. Altered functional and structural connectivity networks in psychogenic non-epileptic seizures.

    Directory of Open Access Journals (Sweden)

    Ju-Rong Ding

    Full Text Available Psychogenic non-epileptic seizures (PNES are paroxysmal behaviors that resemble epileptic seizures but lack abnormal electrical activity. Recent studies suggest aberrant functional connectivity involving specific brain regions in PNES. Little is known, however, about alterations of topological organization of whole-brain functional and structural connectivity networks in PNES. We constructed functional connectivity networks from resting-state functional MRI signal correlations and structural connectivity networks from diffusion tensor imaging tractography in 17 PNES patients and 20 healthy controls. Graph theoretical analysis was employed to compute network properties. Moreover, we investigated the relationship between functional and structural connectivity networks. We found that PNES patients exhibited altered small-worldness in both functional and structural networks and shifted towards a more regular (lattice-like organization, which could serve as a potential imaging biomarker for PNES. In addition, many regional characteristics were altered in structural connectivity network, involving attention, sensorimotor, subcortical and default-mode networks. These regions with altered nodal characteristics likely reflect disease-specific pathophysiology in PNES. Importantly, the coupling strength of functional-structural connectivity was decreased and exhibited high sensitivity and specificity to differentiate PNES patients from healthy controls, suggesting that the decoupling strength of functional-structural connectivity might be an important characteristic reflecting the mechanisms of PNES. This is the first study to explore the altered topological organization in PNES combining functional and structural connectivity networks, providing a new way to understand the pathophysiological mechanisms of PNES.

    We assessed the economic impact to the United States payer of recombinant human growth hormone (rhGH) utilization, comparing the relative dosage efficiency of marketed pen-based and vial-based products in a pediatric and in an adult population. A budgetary impact model calculated drug costs based on product waste and cost. Waste was the difference between prescribed dose, based on patient weight, and actual delivered dose, based on dosing increments and maximum deliverable dose for pens and a fixed-percent waste as derived from the literature for vials. Annual wholesale acquisition costs were calculated based upon total milligrams delivered, using a daily dose of 0.03 mg/kg for pediatric patients and 0.016 mg/kg for adults. Total annual drug costs were compared for two scenarios: 1) a product mix based on national market share and 2) restricting use to the product with lowest waste. Based on the literature, waste for each vial product was 23 percent. Among individual pens, waste was highest for Humatrope 24 mg (19.5 percent pediatric, 14.3 percent adult) and lowest for Norditropin Nordi-Flex 5 mg (1.1 percent pediatric, 1 percent adult). Restricting use to the brand with least waste (Norditropin), compared to national product share mix, resulted in a 10.2 percent reduction in annual pediatric patient cost from $19,026 to $17,089 and an 8 percent reduction in annual adult patient cost from $24,099 to $22,161. We concluded that pen delivery systems result in less waste than vial and syringe. Considering all approved delivery systems, Norditropin resulted in the least product waste and lower annual patient cost for both pediatric and adult populations.

    Campylobacter jejuni is one of the most common causes of bloody diarrhoea in the USA. We report a case of a young woman who presented with a clinical picture reminiscent of acute appendicitis. Ultrasonography and CT of the abdomen performed subsequently revealed evidence of colitis. Quite unexpectedly, she had no symptoms of diarrhoea and the stool Gram stain and culture were negative. Nevertheless, due to high clinical suspicion of infectious colitis, appendectomy was deferred. Blood culture was later reported positive for Campylobacter species and the patient responded to quinolones. With this case report we try to highlight one of the unusual presentations of C jejuni infection, closely mimicking acute appendicitis in the absence of classical symptoms of bacterial enteritis. In such cases, a high index of suspicion, astute history taking skills and the proper use of imaging studies can save the patient from the surgical knife.

  19. A Spectral Based Forecasting Tool of Epileptic Seizures

    Directory of Open Access Journals (Sweden)

    Hedi Khammari

    2012-05-01

    Full Text Available A new approach to recognize and predict succedent epileptic seizure by using single channel electroencephalogram (EEG analysis is proposed. Spectral analysis of a brain time series of the left frontal FP1-F7 (LF scalp location signal is devoted for seizure prediction and analysis. Important findings showing the presence of preictal spectral changes in studied brain signal are described. Spectral features occurring during the preictal epoch are extracted from the application of sliding spectral windows of raw EEG at different moments in time preceding the seizure onset. The same method is then applied to a couple of Intrinsic Mode Functions (IMF1 and IMF2 of the raw EEG (FP1-F7 decomposed by the algorithm of empirical mode decomposition. The main prediction features are derived from the changes of amplitudes, frequency and the number of spikes which are of diagnostic values. The sliding spectral windows were computed to trace the amplitude changes of higher harmonics during time interval preceding the seizure onset. Choosing different moments in time aims to identify the best prediction time of seizure onset. Obviously an early prediction time is always desirable but the seizure may result from an abrupt change and so the spectral 'signs of an imminent seizure occur during a very short prediction time. From another viewpoint, it may be advantageous to consider a successive prediction times showing the increase of spike numbers and the predominance of certain waves rather than others when approaching seizure onset. The common prediction features extracted from the analysis of FP1-F7 signal for both patients were mainly the increasing number of spikes of low frequency waves namely delta and theta waves.

  20. Is the medical home for adult patients with sickle cell disease a reality or an illusion?

    Science.gov (United States)

    Ballas, Samir K; Vichinsky, Elliott P

    2015-01-01

    Recently, the patient-centered medical home (PCMH) emerged as a viable method to improve delivery of medical care. Due to all the promotion about the effectiveness of the PCMH, patients with sickle cell disease, their families and the community hoped that this could be a possible solution to the problems that arise in the treatment of adult patients with sickle cell disease. Review of the literature and review of the criteria for the establishment of a PCMH show that the PCMH is not an ideal model for patients with sickle cell disease because finding a personal physician, which is the first criteria of a functional PCMH, is a major problem in the process of transitioning the care of patients with sickle cell disease from pediatrics to adult care. Moreover, garnering hospital support to defray the initial costs to establish a PCMH for adults with sickle cell disease is unlikely given the already high costs of care for patients with sickle cell disease. Moreover, recent studies have shown insufficient evidence to determine the presumed beneficial effects of the PCMH, especially in patients with chronic disease.

    The aim of this cross-sectional study was to assess the association of olfactory function and nutritional status in vital older adults and geriatric patients. Three hundred forty-five vital (mean age 67.1 years) and 138 geriatric older adults (mean age 80.9 years) were included. Nutritional status was assessed using the mini nutritional assessment-short form. The Sniffin' Sticks was used to measure olfactory function. Eleven percentage of the vital older adults were at risk of malnutrition, whereas 60% of the geriatric participants were malnourished or at risk. Only 2% of the vital older adults were anosmic, compared with 46% of the geriatric participants. Linear regression demonstrated a significant association (P = 0.015) between olfactory function and nutritional status in the geriatric subjects. However, this association became insignificant after adjustment for confounders. Both crude and adjusted analysis in the vital older adults did not show a significant association. The results indicate that, in both groups of elderly, there is no direct relation between olfactory function and nutritional status. We suggest that a decline in olfactory function may still be considered as one of the risk-factors for malnutrition in geriatric patients-once co-occurring with other mental and/or physical problems that are more likely to occur in those patients experience.

  2. Upper and lower urinary tract outcomes in adult myelomeningocele patients: a systematic review.

    Paul W Veenboer

    Full Text Available BACKGROUND: The introduction of sophisticated treatment of bladder dysfunction and hydrocephalus allows the majority of SB patients to survive into adulthood. However, no systematic review on urological outcome in adult SB patients is available and no follow-up schemes exist. OBJECTIVES: To systematically summarize the evidence on outcome of urinary tract functioning in adult SB patients. METHODS: A literature search in PubMed and Embase databases was done. Only papers published in the last 25 years describing patients with open SB with a mean age >18 years were included. We focused on finding differences in the treatment strategies, e.g., clean intermittent catheterization and antimuscarinic drugs versus early urinary diversion, with regard to long-term renal and bladder outcomes. RESULTS: A total of 13 articles and 5 meeting abstracts on urinary tract status of adult SB patients were found describing a total of 1564 patients with a mean age of 26.1 years (range 3-74 years, with a few patients <18 years. All were retrospective cohort studies with relatively small and heterogeneous samples with inconsistent reporting of outcome; this precluded the pooling of data and meta-analysis. Total continence was achieved in 449/1192 (37.7%; range 8-85% patients. Neurological level of the lesion and hydrocephalus were associated with incontinence. Renal function was studied in 1128 adult patients. In 290/1128 (25.7%; range 3-81.8% patients some degree of renal damage was found and end-stage renal disease was seen in 12/958 (1.3% patients. Detrusor-sphincter dyssynergy and detrusor-overactivity acted as adverse prognostic factors for the development of renal damage. CONCLUSIONS: These findings should outline follow-up schedules for SB patients, which do not yet exist. Since renal and bladder deterioration continues beyond adolescence, follow-up of these individuals is needed. We recommend standardization in reporting the outcome of urinary tract function in

    Older adults with multiple conditions receive care that is often fragmented, burdensome, and of unclear benefit. An advisory group of patients, caregivers, clinicians, health system engineers, health care system leaders, payers, and others identified three modifiable contributors to this fragmented, burdensome care: decision making and care focused on diseases, not patients; inadequate delineation of roles and responsibilities and accountability among clinicians; and lack of attention to what matters to patients and caregivers (ie, their health outcome goals and care preferences). The advisory group identified patient priority-directed care as a feasible, sustainable approach to addressing these modifiable factors.

    2015-03-01

    Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

    Full Text Available Abstract Objective Fibrosing colonopathy (FC is a rare entity associated with cystic fibrosis (CF. Until now, patients with stricturing FC have usually been treated surgically. In this instance, we aimed at avoiding surgery by applying a new conservative approach. Methods Case report on an adult with CF who developed persistent abdominal pain due to a non-passable stricture in the right transverse colon. Histology confirmed fibrosing colonopathy. Results Initially we treated the patient with prednisolone pulse therapy and additive antibiotic therapy. For maintenance therapy we administered budesonide. The patient underwent clinical, laboratory and endoscopic follow-up over a three-year period. The stricture healed and was easy to pass. A relapse in the cecum at the ileocecal valve again improved under steroid and antibiotic therapy. Conclusions We present a novel therapeutic approach for advanced stricturing FC in an adult patient which successfully avoided surgery (right hemicolectomy over a three year follow up.

  8. Modulation of epileptic activity by deep brain stimulation: a model-based study of frequency-dependent effects.

    A number of studies showed that deep brain stimulation (DBS) can modulate the activity in the epileptic brain and that a decrease of seizures can be achieved in "responding" patients. In most of these studies, the choice of stimulation parameters is critical to obtain desired clinical effects. In particular, the stimulation frequency is a key parameter that is difficult to tune. A reason is that our knowledge about the frequency-dependant mechanisms according to which DBS indirectly impacts the dynamics of pathological neuronal systems located in the neocortex is still limited. We address this issue using both computational modeling and intracerebral EEG (iEEG) data. We developed a macroscopic (neural mass) model of the thalamocortical network. In line with already-existing models, it includes interconnected neocortical pyramidal cells and interneurons, thalamocortical cells and reticular neurons. The novelty was to introduce, in the thalamic compartment, the biophysical effects of direct stimulation. Regarding clinical data, we used a quite unique data set recorded in a patient (drug-resistant epilepsy) with a focal cortical dysplasia (FCD). In this patient, DBS strongly reduced the sustained epileptic activity of the FCD for low-frequency (LFS, 70 Hz) while intermediate-frequency stimulation (IFS, around 50 Hz) had no effect. Signal processing, clustering, and optimization techniques allowed us to identify the necessary conditions for reproducing, in the model, the observed frequency-dependent stimulation effects. Key elements which explain the suppression of epileptic activity in the FCD include: (a) feed-forward inhibition and synaptic short-term depression of thalamocortical connections at LFS, and (b) inhibition of the thalamic output at HFS. Conversely, modeling results indicate that IFS favors thalamic oscillations and entrains epileptic dynamics.

  13. Brain mechanisms of altered conscious states during epileptic seizures.

    Science.gov (United States)

    Cavanna, Andrea Eugenio; Monaco, Francesco

    2009-05-01

    Impaired consciousness has long been considered the hallmark of epileptic seizures. Both generalized seizures and complex partial seizures are characterized by a multifaceted spectrum of altered conscious states, in terms of the general level of awareness and the subjective contents of consciousness. Complete loss of consciousness occurs when epileptic activity involves both cortical and subcortical structures, as in tonic-clonic seizures and absence seizures. Medial temporal lobe discharges can selectively impair experience in complex partial seizures (with affected responsiveness) and certain simple partial seizures (with unaffected responsiveness). Electrical stimulation of temporal lobe structures has been shown to evoke similar subjective experiences. Findings from neurophysiological and brain-imaging studies in epilepsy have now demonstrated that involvement of the bilateral thalamus and upper brainstem leads to selective impairment of frontoparietal association cortices and midline 'default mode' networks, which results in ictal loss of consciousness. The spread of epileptic discharges from the medial temporal lobe to the same subcortical structures can ultimately cause impairment in the level of consciousness in the late ictal and immediate postictal phase of complex partial seizures. This paper reviews novel insights into the brain mechanisms that underlie alterations of consciousness during epileptic seizures and the implications for clinical practice in terms of diagnosis and management.

    Focal somatosensory epileptic seizures ipsilateral to a brain tumor is reported and the literature reviewed. It is an exceptional occurrence, having been described only six cases, with several mechanisms being proposed. The proximity of the lesions with the low cerebral convexity (perisylvian) suggests the compromising of the secondary somatosensorial area, seeming to prove the experimental observation of somatosensorial crises originating in this area.

    Epidemiological studies indicate that separation anxiety disorder occurs more frequently in adults than children. It is unclear whether the presence of adult separation anxiety disorder (ASAD) is a manifestation of anxious attachment, or a form of agoraphobia, or a specific condition with clinically significant consequences. We conducted a study to examine these questions. A sample of 141 adult outpatients with panic disorder participated in the study. Participants completed standardized measures of separation anxiety, attachment style, agoraphobia, panic disorder severity and quality of life. Patients with ASAD (49.5% of our sample) had greater panic symptom severity and more impairment in quality of life than those without separation anxiety. We found a greater rate of symptoms suggestive of anxious attachment among panic patients with ASAD compared to those without ASAD. However, the relationship between ASAD and attachment style is not strong, and adult ASAD occurs in some patients who report secure attachment style. Similarly, there is little evidence for the idea that separation anxiety disorder is a form of agoraphobia. Factor analysis shows clear differentiation of agoraphobic and separation anxiety symptoms. Our data corroborate the notion that ASAD is a distinct condition associated with impairment in quality of life and needs to be better recognized and treated in patients with panic disorder.

    Full Text Available In this study, we aimed to demonstrate whether spontaneous fluctuations in the blood oxygen level dependent (BOLD signal derived from resting state functional magnetic resonance imaging (fMRI reflect spontaneous neuronal activity in pathological brain regions as well as in regions spared by epileptiform discharges. This is a crucial issue as coherent fluctuations of fMRI signals between remote brain areas are now widely used to define functional connectivity in physiology and in pathophysiology. We quantified functional connectivity using non-linear measures of cross-correlation between signals obtained from intracerebral EEG (iEEG and resting-state functional MRI (fMRI in 5 patients suffering from intractable temporal lobe epilepsy (TLE. Functional connectivity was quantified with both modalities in areas exhibiting different electrophysiological states (epileptic and non affected regions during the interictal period. Functional connectivity as measured from the iEEG signal was higher in regions affected by electrical epileptiform abnormalities relative to non-affected areas, whereas an opposite pattern was found for functional connectivity measured from the BOLD signal. Significant negative correlations were found between the functional connectivities of iEEG and BOLD signal when considering all pairs of signals (theta, alpha, beta and broadband and when considering pairs of signals in regions spared by epileptiform discharges (in broadband signal. This suggests differential effects of epileptic phenomena on electrophysiological and hemodynamic signals and/or an alteration of the neurovascular coupling secondary to pathological plasticity in TLE even in regions spared by epileptiform discharges. In addition, indices of directionality calculated from both modalities were consistent showing that the epileptogenic regions exert a significant influence onto the non epileptic areas during the interictal period. This study shows that functional

    Over the last few decades, there has been increasing awareness among epileptologists about the need to refine our understanding and assessment of ictal consciousness, focusing on both subjective and behavioral aspects of seizures. Specifically, there have been suggestions that both the internal and external milieux - the former related to the phenomenal qualia of experience, the latter related to behavior - must be taken into account for a better understanding of altered states of consciousness in epilepsy. It has been proposed that clinical and experimental data from patients experiencing alterations of consciousness during epileptic seizures could be better understood within a bidimensional model, in which any manifestation of conscious experience can be plotted according to the level and contents of consciousness. The 'level' axis measures the degree of alertness/arousal, whereas the 'contents' axis measures the vividness of specific experiential phenomena reported by the patient. We argue that certain seizure types might require more rigorous conceptual models for their characterization, and we highlight the potential usefulness of a more refined framework which includes a further dimension related to the 'self', in addition to those of 'level' and 'contents'. This model could be visualized in a three-dimensional space to allow fine-grained distinctions between epileptic seizures.

  11. Recurrent prolonged fugue states as the sole manifestation of epileptic seizures

    Full Text Available A fugue state is defined as an altered state of consciousness with varying degrees of motor activity and amnesia for the event. It may last for hours to days and may be psychogenic or organic in nature. Epileptic fugue states can be encountered in patients with absence or complex partial nonconvulsive status epilepticus or may occur as a postictal phenomenon in patients with generalized seizures. ′′absence status epilepticus′′ (AS is rare and seen in only 2.6% of the cases with ′′childhood absence epilepsy′′ (CAE. The diagnosis of AS can be elusive, but sudden onset and termination of the fugue state, classical electroencephalogram (EEG features, and response to a therapeutic trial of benzodiazepines helps in confirming the diagnosis and differentiating it from nonepileptic fugue states. We report a childhood onset case, with a 10 years history of recurrent episodes of prolonged fugue state lasting for up to 24 h, as the sole manifestation of epileptic seizures. The EEG features were suggestive of an AS, but there was no history of typical absences, myoclonus, or generalized tonic clonic seizures. This unusual and rare case cannot be categorized into one of the defined epilepsy syndromes like CAE but belongs to a recently identified syndrome of idiopathic generalized epilepsy known as ′′Absence status epilepsy′′ in which AS is the sole or the predominant seizure type.

  12. Weighted and directed interactions in evolving large-scale epileptic brain networks

    Epilepsy can be regarded as a network phenomenon with functionally and/or structurally aberrant connections in the brain. Over the past years, concepts and methods from network theory substantially contributed to improve the characterization of structure and function of these epileptic networks and thus to advance understanding of the dynamical disease epilepsy. We extend this promising line of research and assess—with high spatial and temporal resolution and using complementary analysis approaches that capture different characteristics of the complex dynamics—both strength and direction of interactions in evolving large-scale epileptic brain networks of 35 patients that suffered from drug-resistant focal seizures with different anatomical onset locations. Despite this heterogeneity, we find that even during the seizure-free interval the seizure onset zone is a brain region that, when averaged over time, exerts strongest directed influences over other brain regions being part of a large-scale network. This crucial role, however, manifested by averaging on the population-sample level only – in more than one third of patients, strongest directed interactions can be observed between brain regions far off the seizure onset zone. This may guide new developments for individualized diagnosis, treatment and control.

    In order to assess the CT diagnosis of suspected acute appendicitis, we performed abdominal contrasted CT measurements in 77 patients from 20 to 86 years old, and of 50 men and 27 women from June 1993 to June 1996. The surgical findings were compared with the preoperative CT findings. By the preoperative CT imaging, we can know the degree and the position of inflammation in appendix vermiformis and the degree and the spread of periappendicular inflammation in the case of appendicitis, and can make a differential diagnosis of diverticulitis or gynecological diseases from appendicitis. It is important to make a preoperative diagnosis by the objectively excellent abdominal CT imaging and to avoid unnecessary surgery. (K.H.)

    Elongated and spaced incisors are common problems in patients suffering from severe periodontal disease. Thirty patients characterized by marginal bone loss and deep overbite were treated by intrusion of incisors. Three different methods for intrusion were applied: (1) J hooks and extraoral high-pull headgear, (2) utility arches, (3) intrusion bent into a loop in a 0.17 x 0.25-inch wire, and (4) base arch as described by Burstone. The intrusion was evaluated from the displacement of the apex, incision, and the center of resistance of the most prominent or elongated central incisor. Change in the marginal bone level and the amount of root resorption were evaluated on standardized intraoral radiographs. The pockets were assessed by standardized probing and the clinical crown length was measured on study casts. The results showed that the true intrusion of the center of resistance varied from 0 to 3.5 mm and was most pronounced when intrusion was performed with a base arch. The clinical crown length was generally reduced by 0.5 to 1.0 mm. The marginal bone level approached the cementoenamel junction in all but six cases. All cases demonstrated root resorption varying from 1 to 3 mm. The total amount of alveolar support--that is, the calculated area of the alveolar wall--was unaltered or increased in 19 of the 30 cases. The dependency of the results on the oral hygiene, the force distribution, and the perioral function was evaluated in relation to the individual cases. It was obvious that intrusion was best performed when (1) forces were low (5 to 15 gm per tooth) with the line of action of the force passing through or close to the center of resistance, (2) the gingiva status was healthy, and (3) no interference with perioral function was present.

    Full Text Available Stigmatization is a major hindrance in adult psychiatric patients with Axis-I diagnoses, as shown consistently in most studies. Significantly fewer studies on the emergence of psychiatric stigma in adult patients with personality disorders exist, although the resulting evidence is conclusive. Some authors consider patients with personality disorders at risk for severe stigmatization because of intense difficulties during interpersonal contact, even in a psychotherapeutic relationship. The aim of this study was primarily the assessment of pre-existing stigma in patients referred for intensive treatment for personality disorders. The study enrolled 214 patients admitted to the adult department of a highly specialized mental health care institute offering psychotherapy for patients with severe and complex personality pathology. All patients underwent a standard assessment with self-report questionnaires and a semi-structured interview to measure Axis II personality disorders. The Stigma Consciousness Questionnaire (SCQ and the Perceived Devaluation-Discrimination Questionnaire (DDQ, both validated instruments, were used to measure perceived and actual experiences of stigma. Independent sample t-tests were used to investigate differences in the mean total stigma scores for patients both with and without a personality disorder. One-way ANOVA’s were performed to assess the differences between having a borderline personality disorder, another personality disorder, or no personality disorder diagnosis.Multiple regression main effect analyses were conducted in order to explore the impact of the different personality disorder diagnosis on the level of stigma. The mean scores across all patient groups were consistent with rather low stigma. No differences were found for patients with or without a personality disorder diagnosis. Level of stigma in general was not associated with an accumulating number of personality disorders.

    Background Anemia is a major public health problem in HIV patients around the world. It has a negative effect on the quality of life of HIV patients and progression of the HIV disease. In the sub-Saharan African setting, including Ethiopia where both HIV infection and under-nutrition are expected to be high, there is a paucity of data on the matter. This study was aimed to reveal the magnitude and factors associated with anemia among adult HIV patients in Debre-Tabor Hospital, northwest Ethiopia. Methods A hospital-based cross-sectional study was used among adult HIV patients in Debre-Tabor Hospital from April 1 to May 30, 2015. The diagnosis of anemia was made following the 2011 World Health Organization recommendation on hemoglobin cut-off points. Univariable and multivariable logistic regression was carried out to assess factors associated with anemia. Results A total of 377 patients’ charts were reviewed. Most of the participants (n=237, 62.9%) were taking antiretroviral treatment (ART). The overall prevalence of anemia was 23% (95% CI: 19.1, 27.6). Being ART-naïve (adjusted odds ratio [AOR]: 3.37; 95% CI: 1.59, 7.14), having treatment history with anti-tuberculosis (TB) drug (AOR: 3.2; 95% CI: 1.19, 8.67), taking zidovudine (ZDV)-containing ART regimen (AOR: 2.14; 95% CI: 1.03, 4.57), and having recent CD4+ T-lymphocytes count of HIV patients. Conclusion and recommendation Anemia continues to be a major co-morbidity among adult HIV patients in Ethiopia. Adult HIV patients who are taking ZDV-containing ART, with a history of TB treatment, have a low CD4+T-lymphocytes count and are ART-naïve should be carefully screened and treated for anemia.

    Full Text Available Epilepsy in the elderly has high incidence and prevalence and is often underecognized. Objective To describe etiological prevalence of epilepsy and epileptic seizures in elderly inpatients. Methods Retrospective analysis was performed on elderly patients who had epilepsy or epileptic seizures during hospitalization, from January 2009 to December 2010. One hundred and twenty patients were enrolled. They were divided into two age subgroups (median 75 years with the purpose to compare etiologies. Results The most common etiology was ischemic stroke (36.7%, followed by neoplasias (13.3%, hemorrhagic stroke (11.7%, dementias (11.4% and metabolic disturbances (5.5%. The analysis of etiological association showed that ischemic stroke was predominant in the younger subgroup (45% vs 30%, and dementias in the older one (18.9% vs 3.8%, but with no statistical significance (p = 0.23. Conclusion This study suggests that epilepsy and epileptic seizures in the elderly inpatients have etiological association with stroke, neoplasias and dementias.

  19. Impaired dendritic inhibition leads to epileptic activity in a computer model of CA3.

    Temporal lobe epilepsy (TLE) is a common type of epilepsy with hippocampus as the usual site of origin. The CA3 subfield of hippocampus is reported to have a low epileptic threshold and hence initiates the disorder in patients with TLE. This study computationally investigates how impaired dendritic inhibition of pyramidal cells in the vulnerable CA3 subfield leads to generation of epileptic activity. A model of CA3 subfield consisting of 800 pyramidal cells, 200 basket cells (BC) and 200 Oriens-Lacunosum Moleculare (O-LM) interneurons was used. The dendritic inhibition provided by O-LM interneurons is reported to be selectively impaired in some TLEs. A step-wise approach is taken to investigate how alterations in network connectivity lead to generation of epileptic patterns. Initially, dendritic inhibition alone was reduced, followed by an increase in the external inputs received at the distal dendrites of pyramidal cells, and finally additional changes were made at the synapses between all neurons in the network. In the first case, when the dendritic inhibition of pyramidal cells alone was reduced, the local field potential activity changed from a theta-modulated gamma pattern to a prominently gamma frequency pattern. In the second case, in addition to this reduction of dendritic inhibition, with a simultaneous large increase in the external excitatory inputs received by pyramidal cells, the basket cells entered a state of depolarization block, causing the network to generate a typical ictal activity pattern. In the third case, when the dendritic inhibition onto the pyramidal cells was reduced and changes were simultaneously made in synaptic connectivity between all neurons in the network, the basket cells were again observed to enter depolarization block. In the third case, impairment of dendritic inhibition required to generate an ictal activity pattern was lesser than the two previous cases. Moreover, the ictal like activity began earlier in the third case

    Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

    Full Text Available Cerebellar agenesis (CA is an extremely rare entity. We present two adult patients with CA. The 61-year-old man had ataxia, dysarthria, abnormalities in cerebellar tests, severe cognitive impairment, and moderate mental retardation. The 26-year-old woman had dysmetria, dysdiadochokinesia, and dysarthria as well as mild cognitive impairment and mild mental retardation. Magnetic resonance imaging (MRI showed complete absence of the cerebellum with small residual vermis. Brainstem was hypoplastic and structures above tentorium were normal. Supratentorial white matter bundles were unaffected in diffusion tensor tractography. Only few adult patients with CA have so far been published. These cases show that patients with CA present with a variety of developmental, clinical, and mental abnormalities; and emphasize the role of the cerebellum in normal motor, language, and mental development.

    2015-01-01

    The Internet has increasing relevance and practical use as a tool to support cancer care. For example, health support Web sites are now widely used to connect specific groups of patients who may otherwise have remained isolated, and understanding their health-related online behaviors will help in the development of more effective health support Web sites. This article examined blogs written by young adults affected by cancer and in particular examined the gender differences in these blog entries through content analysis. The results showed there is little difference in blog content between genders. This suggests that the blog environment could lessen the gender-typical behaviors often expected by society and may provide an outlet for young adult cancer patients to more freely share their cancer-related experiences, at the same time providing an opportunity for social connection. This is particularly significant for male patients who are known to inhibit their emotions as well as the expression of their health concerns.

    This article provides the first assessment of theory of mind, that is, the ability to reason about mental states, in adult patients with congenital heart disease. Patients with congenital heart disease and matched healthy controls were administered classical theory of mind tasks and a semi-structured interview which provides a multidimensional evaluation of theory of mind (Theory of Mind Assessment Scale). The patients with congenital heart disease performed worse than the controls on the Theory of Mind Assessment Scale, whereas they did as well as the control group on the classical theory-of-mind tasks. These findings provide the first evidence that adults with congenital heart disease may display specific impairments in theory of mind.

    Adult-onset GH deficiency (GHD), mostly due to organic lesions of the pituitary-hypothalamic region, is frequently associated with multiple anterior pituitary deficiencies that need long-term substitutive treatment. The GH-IGF-I axis may play an important role in modulating peripheral metabolism of hormones (adrenal, thyroid, and sex hormones) and these interactions may have clinically significant implications on the phenotypes of adult GHD patients and on the effects of the combined replacement hormonal treatment of this condition. By accelerating the peripheral metabolism of cortisol, GH therapy may precipitate adrenal insufficiency in susceptible hypopituitary patients; estrogen replacement blunts the response to GH in women whereas in men with androgen substitution the responsivity increases over time. Endocrinologists should be mindful of these phenomena when starting patients with hypopituitarism on GH replacement therapy.

    Aortic coarctation is a disease that usually presents in infancy; however, a proportion of patients present for the first time in adulthood. These lesions generally require repair with either surgery or interventional techniques. The success of these techniques means that increasing numbers of patients are presenting for follow-up imaging in adulthood, whether their coarctation was initially repaired in infancy or as adults. Thus, the adult presenting to the radiologist for assessment of possible coarctation or follow-up of coarctation repair is not an uncommon scenario. In this review, we present details of the MRI protocols and MRI findings in these patients so that a confident and accurate assessment can be made.

    Combined duplication of the colon and vermiform appendix is one of the rare congenital anomalities of the alimentary tract. Only a few cases have been reported in the adult population. A 28-year-old man presented to the clinic with a mass in the right flank. Imaging showed only a hydronephrotic atrophic kidney. The final diagnosis was only available at exploration. Combined duplication of the tubular colon and vermiform appendix was confirmed histopathologically. The patient was treated with nephrectomy and complete resection of the duplicated colon and vermiform appendix. The patient recovered uneventfully, and has done well for the past year. This is believed to be one of the first reports of combined duplication of the tubular colon and vermiform appendix as a cause of hydronephrotic atrophic kidney in an adult patient.

Iran J Child Neurol. 2014 Winter; 8(1:26-31.ObjectiveAlthough the use of Complementary and Alternative Medicine (CAM has been evaluated globally, there are few studies in our country on this subject. The purpose of this study was to determine the prevalence, pattern of use, parental sources of information, and benefits of CAM in epileptic children in Tehran.Materials & MethodsOne hundred thirty-three parents or relatives of epileptic children who were referred to outpatient clinics or admitted in neurologic ward of four major hospitals in Tehran, were interviewed by our researcher based on a structured questionnaire; from 2009 to 2010. The information obtained comprised the demographic data of patients and their parents, frequency and morphology of convulsions, the type and sources of CAM and finally, the benefits and adverseeffects of this practice.ResultsForty-four percent of the respondents had used CAM methods either alone or in combination with other methods. The most frequently used CAM was written prayers followed by oral herbs and special diets. CAM was mainly introduced to them by relatives. Only 16.7% of these parents had discussed this matter with their children’s physicians. No efficacy to control seizure was observed for most of these methods.ConclusionThis study showed that use of CAM in our study group is relatively common and may have a potentially hazardous role in the treatment process. So, it is necessary for physicians to have enough information about CAM practice in their patients. References:National Institutes of health.

    Recently released recommendations for detection and documentation of malnutrition in adults in clinical practice define 3 types of malnutrition: starvation related, acute disease or injury related, and chronic disease related. The first 2 are more easily recognized, but the third may be more often unnoticed, particularly in obese patients. Critical care patients tend to be at high risk for malnutrition and thus require a thorough nutritional assessment. Compared with patients of earlier times, intensive care unit patients today tend to be older, have more complex medical and comorbid conditions, and often are obese. Missed or delayed detection of malnutrition in these patients may contribute to increases in hospital morbidity and longer hospital stays. Critical care nurses are in a prime position to screen patients at risk for malnutrition and to work with members of the interprofessional team in implementing nutritional intervention plans.

    Complete rupture of the hamstring tendons in the adult is a rare injury. This report discusses complete rupture of the hamstring tendons in nine patients treated by late operative repair. All patients were referred from outside centers for a second opinion after failed nonoperative treatment. The diagnosis was made quite easily on clinical grounds and was confirmed at surgery. Surgical treatment in all cases consisted of reattachment of the hamstring tendons to the origin on the ischium, and in all cases it was necessary to perform neurolysis of the sciatic nerve. Good results were achieved in all cases, at follow-up all patients were satisfied with the surgery.

    Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is a rare autosomal dominant disorder with multiple manifestations including early onset of cutaneous basal cell carcinomas (BCCs). Radiotherapy has traditionally been contraindicated due to reports of BCC induction. We describe here a patient treated successfully with radiotherapy with no tumour induction at 57 months of follow-up. A comprehensive literature review of radiotherapy outcomes in patients with Gorlin syndrome suggests radiotherapy may be a feasible treatment option for adult patients with treatment refractory lesions or surgical contraindication.

    Computed tomography coronary angiography is increasingly used in imaging departments in the investigation of patients with chest pain and suspected coronary artery disease. Due to the routine use of heart rate controlling medication and the potential for very high radiation doses during these scans, there is a need for guidance on best practice for departments performing this examination, so the patient can be assured of a good quality scan and outcome in a safe environment. This article is a summary of the document on 'Standards of practice of computed tomography coronary angiography (CTCA) in adult patients' published by the Royal College of Radiologists (RCR) in December 2014.

    OBJECTIVE Adult-onset hydrocephalus is not commonly discussed in the literature, especially regarding its demographic distribution. In contrast to pediatric hydrocephalus, which is related to a primary CSF pathway defect, its development in adults is often secondary to other pathologies. In this study, the authors investigated the epidemiology of adult-onset hydrocephalus as it pertains to different etiologies and in reference to age, sex, and race distributions. METHODS The authors retrospectively reviewed the clinical notes of 2001 patients with adult-onset hydrocephalus who presented to Louisiana State University Health Sciences Center within a 25-year span. Significant differences between the groups were analyzed by a chi-square test; p hydrocephalus in this population was 77 ± 30 per year, with a significant increase in incidence in the past decade (55 ± 3 [1990-2003] vs 102 ± 6 [2004-2015]; p Hydrocephalus in a majority of the patients had a vascular etiology (45.5%) or was a result of a tumor (30.2%). The incidence of hydrocephalus in different age groups varied according to various pathologies. The incidence was significantly higher in males with normal-pressure hydrocephalus (p = 0.03) or head injury (p = 0.01) and higher in females with pseudotumor cerebri (p hydrocephalus was significantly higher in Caucasian patients (p = 0.0002) than in those of any other race. CONCLUSIONS Knowledge of the demographic variations in adult-onset hydrocephalus is helpful in achieving better risk stratification and better managing the disease in patients. For general applicability, these results should be validated in a large-scale meta-analysis based on a national population database.

    Full Text Available BACKGROUND: The nephrotic syndrome is recognized as an independent entity of renal disease for over half a century . 1 Causes of nephrotic syndrome varies with age, time period, geographical location and race. In children, minimal change nephrotic syndrome is the commonest 2 ; however, membranous nephropathy is most frequent in adults . 3 As it commonly affects the younger age group and is associated with high morbidity and mortality, there is a need to understand and diagnose the disease at an early stage. Hence, this study has been done to identify the clinical presentation, biochemical parameters and histopathology associated with nephrotic syndrome in adults and its subtypes. OBJECTIVE: To study the clinical, biochemical and histopathological profile of patients with Adult Nephrotic Syndrome admitted in our tertiary care hospital. METHODS: Prospective study of 100 patients with Adult Nephrotic Syndrome admitt ed in our tertiary care hospital were screened with facial puffiness and pedal edema. They were tested for urine proteinuria, urine protein creatinine ratio or 24 hour urine protein estimation. Later renal biopsy was done for all patients to stratify the subtypes. RESULTS: In this study, males were predominantly affected. Most common presenting complaints were facial puffiness and pedal edema. Systolic BP was increased in 96% of patients and diastolic BP was elevated in 50% of patients. Serum LDL and TGL were elevated in nephrotic syndrome. In young patients less than 40 years Focal Segmental Glomerulosclerosis (FSGS is the commonest type, then Membrano Proliferative Glomerulo Nephritis (MPGN and Minimal Change Disease (MCD. In individuals more than 40 years, membranous nephropathy was predominantly seen followed by FSGS. CONCLUSION: There is a changing trend in primary nephrotic syndrome and FSGS was found to be the commonest subtype. Male preponderance was noticed and also FSGS was found to be more common in younger adults. Most

    Full Text Available The adaptive behavior of human beings is usually supported by rapid monitoring of outstanding events in the environment. Some investigators have suggested that a primary attention deficit might trigger symptoms of schizophrenia. In addition, researchers have long discussed the relationship between schizophrenia and the schizophrenia-like psychosis of epilepsy (SLPE. On the basis of these considerations, the objective of the present study was to investigate attention performance of patients with both disorders. Patient age was 18 to 60 years, and all patients had received formal schooling for at least four years. Patients were excluded if they had any systemic disease with neurologic or psychiatric comorbidity, or a history of brain surgery. The computer-assisted TAVIS-2R test was applied to all patients and to a control group to evaluate and discriminate between selective, alternating and sustained attention. The TAVIS-2R test is divided into three parts: one for selective attention (5 min, the second for alternating attention (5 min, and the third for the evaluation of vigilance or sustained attention (10 min. The same computer software was used for statistical analysis of reaction time, omission errors, and commission errors. The sample consisted of 36 patients with schizophrenia, 28 with interictal SLPE, and 47 healthy controls. The results of the selective attention tests for both patient groups were significantly lower than that for controls. The patients with schizophrenia and SLPE performed differently in the alternating and sustained attention tests: patients with SLPE had alternating attention deficits, whereas patients with schizophrenia showed deficits in sustained attention. These quantitative results confirmed the qualitative clinical observations for both patient groups, that is, that patients with schizophrenia had difficulties in focusing attention, whereas those with epilepsy showed perseveration in attention focus.

    Introduction: There is paucity of studies evaluating the role of cranial imaging in the management of status epilepticus (SE); therefore this study evaluates the role of imaging in predicting the outcome of SE. Methods: Consecutive patients with SE were prospectively evaluated. Clinical evaluation, blood counts, serum chemistry and cerebrospinal fluid (CSF) were carried out. Cranial CT scan was performed on a spiral CT and MRI on a 1.5 T scanner. Patients were treated with IV sodium valproate, phenytoin and benzodiazepines as per fixed protocol. Outcome was defined as seizure control at 1 h and mortality. Various clinical and radiological parameters were correlated. Results: There were 99 patients with SE whose mean age was 35 (1-78) years, 40 females and 17 were below 12 years of age. Fifty six patients had central nervous system (CNS) infections, 15 strokes, 13 metabolic encephalopathy, 5 drug default and in the remaining 10 patients various acute symptomatic causes were present. Cranial imaging was abnormal in 59% patients. CT was abnormal in 21 (47.7%) out of 44 patients whereas MRI was abnormal in 26 (63.4%) out of 41 patients. Both MRI and CT were carried out in 14 patients and 12 revealed abnormalities; 2 had abnormality only on MRI. Imaging revealed cortical lesions in 10, subcortical in 19 and both cortical as well as subcortical in 30 patients. One hour seizure control was achieved in 60, seizures recurred within 24 h in 38 and 27 patients died during hospital stay. Seizure type, duration of SE, seizure control at 1 h and mortality did not correlate with radiological abnormalities. Conclusion: Cranial imaging reveals structural abnormality in 59% patients with SE and was not related to SE control and mortality.

    Full Text Available Controversy exists as to whether obesity constitutes a risk-factor or a protective-factor for the development of nosocomial Infection (NI. According to the obesity-paradox, there is evidence that moderate obesity is a protective-factor. In Mexico few studies have focused on the nutritional status (NS distribution in the hospital setting.The aim of this study was to estimate the distribution of NS and the prevalence of nosocomial infection NI among adult elective surgery (ES patients and to compare the clinical and anthropometric characteristics and length of stays (LOS between obese and non-obese patients and between patients with and without NI.We conducted a cross-sectional study with a sample (n = 82 adult ES patients (21-59 years old who were recruited from a tertiary-care hospital. The prevalences of each NS category and NI were estimated, the assessments were compared between groups (Mann-Whitney, Chi-squared or the Fisher's-exact-test, and the association between preoperative risk-factors and NI was evaluated using odds ratios.The distribution of subjects by NS category was: underweight (3.66%, normal-weight (28.05%, overweight (35.36%, and obese (32.93%. The prevalence of NI was 14.63%. The LOS was longer (p<0.001 for the patients who developed NI. The percentages of NI were: 33.3% in underweight, 18.52% in obese, 17.39% in normal-weight, and 6.90% in overweight patients.The prevalence of overweight and obesity in adult ES patients is high. The highest prevalence of NI occurred in the underweight and obese patients. The presence of NI considerably increased the LOS, resulting in higher medical care costs.

    The availability of safe and effective factor replacement therapies, in persons with haemophilia (PWH), has in some countries answered the basic need for treatment of these patients. The findings suggest that adult patients who have always been on prophylaxis reported significantly better physical functioning, and thus better quality of life. This study is designed to evaluate the QoL in adult PWH, by focusing on social determinants of QoL and their relationship with health-related dimensions, in Tabriz, Iran. The survey instrument was a self-report 36 items questionnaire, 'A36 Hemofilia - QoL', which is a disease-specific questionnaire for the assessment of the health-related QoL in adults living with haemophilia. A total of 100 haemophilia A and B patients, aged over 17 years participated in this study within 1 year. QoL total score was 71.88 (±26.89 SD). Patients who treat in our Hemophilia Treatment Center, had better QoL score (P = 0.000), and education has a significant impact on the social aspects of QoL (P = 0.18). The QoL was very poor in urban area in contrast to patients who lived in the city (54.45 vs. 74.21 respectively). Single patients have a better QoL than married patients (76.56 vs. 68.50 respectively). Our results showed that low education and lack of awareness of the diseases among PWH lead to reduce of QoL and more disease complications. More and wider treatment and psychological care for improving quality of life of these patients are seriously recommended.

    The standard treatment in children with average-risk medulloblastoma (MB) is reduced-dose radiotherapy (RT) followed by chemotherapy. However, in adults, there is no agreement on the use of adjuvant chemotherapy. We performed a retrospective analysis of adult MB patients with average-risk disease, defined as no postsurgical residual (or ≤1.5 cm(2)) and no metastatic disease (M0). Main inclusion criteria were: age >16 years, post-surgical treatment with craniospinal irradiation with or without adjuvant chemotherapy (cisplatin and etoposide ± cyclophosphamide). From 1988 to 2012 were accrued 43 average-risk MB patients treated with surgery and adjuvant RT. Fifteen (34.9 %) patients received also chemotherapy: 7 before RT, 5 after RT, and 3 before and after RT. Reasons to administer chemotherapy were presence of residual disease (even if ≤1.5 cm) and delay in RT. After a median follow up time of 10 years (range: 8-13), median survival was 18 years (95 % CI 9-28) in patients who receive RT alone, and was not reached in patients treated with RT plus chemotherapy. The survival rates at 5, 10 and 15 years were 100 %, 78.6 % (95 % CI 60.0-97.2 %) and 60.2 % (95 % CI 36.9-83.5 %), in patients treated with RT alone, and 100, 100 and 100 %, in patients treated with RT plus chemotherapy (p = 0.079). Our findings suggest a role for adjuvant chemotherapy in the treatment of average-risk MB adult patients. Further improvements might drive to add chemotherapy in average-risk setting with less favourable biological signatures (i.e., non-WNT group).

    Although epilepsy is associated with a variety of abnormalities, exactly why some brain regions produce seizures and others do not is not known. We developed a method to identify cellular changes in human epileptic neocortex using transcriptional clustering. A paired analysis of high and low spiking tissues recorded in vivo from 15 patients predicted 11 cell-specific changes together with their 'cellular interactome'. These predictions were validated histologically revealing millimetre-sized 'microlesions' together with a global increase in vascularity and microglia. Microlesions were easily identified in deeper cortical layers using the neuronal marker NeuN, showed a marked reduction in neuronal processes, and were associated with nearby activation of MAPK/CREB signalling, a marker of epileptic activity, in superficial layers. Microlesions constitute a common, undiscovered layer-specific abnormality of neuronal connectivity in human neocortex that may be responsible for many 'non-lesional' forms of epilepsy. The transcriptional clustering approach used here could be applied more broadly to predict cellular differences in other brain and complex tissue disorders.

  7. Examination of the wavelet-based approach for measuring self-similarity of epileptic electroencephalogram data

    Self-similarity or scale-invariance is a fascinating characteristic found in various signals including electroencephalogram (EEG) signals. A common measure used for characterizing self-similarity or scale-invariance is the spectral exponent. In this study, a computational method for estimating the spectral exponent based on wavelet transform was examined. A series of Daubechies wavelet bases with various numbers of vanishing moments were applied to analyze the self-similar characteristics of intracranial EEG data corresponding to different pathological states of the brain, i.e., ictal and interictal states, in patients with epilepsy. The computational results show that the spectral exponents of intracranial EEG signals obtained during epileptic seizure activity tend to be higher than those obtained during non-seizure periods. This suggests that the intracranial EEG signals obtained during epileptic seizure activity tend to be more self-similar than those obtained during non-seizure periods. The computational results obtained using the wavelet-based approach were validated by comparison with results obtained using the power spectrum method.

    Full Text Available The increasing prevalence of celiac disease (CD, especially in adults, its atypical clinical presentation, and the strict, lifelong adherence to gluten-free diet (GFD as the only option for healthy state create an imperative need for noninvasive methods that can effectively diagnose CD and monitor GFD. Aim. Evaluation of anti-endomysium (EmA and anti-tissue transglutaminase IgA (tTG-A antibodies in CD diagnosis, GFD monitoring, and first degree relatives screening in CD adult patients. Methods. 70 newly diagnosed Greek adult patients, 70 controls, and 47 first degree relatives were tested for the presence of EmA and tTG-A. The CD patients were monitored during a 3-year period. Results. EmA predictive ability for CD diagnosis was slightly better compared to tTG-A (P=0.043. EmA could assess compliance with GFD already from the beginning of the diet, while both EmA and tTG-A had an equal ability to discriminate between strictly and partially compliant patients after the first semester and so on. Screening of first degree relatives resulted in the identification of 2 undiagnosed CD cases. Conclusions. Both EmA and tTG-A are suitable markers in the CD diagnosis, in the screening of CD among first degree relatives, having also an equal performance in the long term monitoring.

    We evaluated the regional cerebral glucose metabolism in adult patients with neurofibromatosis (NF) using visual and SPM analysis, and compared with MRI findings. A total of 11 adult patients with NF type I were prospectively included in the study. All patients underwent F-18 FDG PET and brain MRI within 2 month of each other. All hypometabolic areas on PET were determined visually by 2 nuclear medicine physician and compared with MRI findings. SPM analysis was done using 42 normal controls with p = 0.005. Seven of 11 PET images showed 10 hypometabolic areas and 4 of 11 MRIs showed 6 areas of signal change brain parenchyma. Hypometabolic areas were bilateral thalamus (n=5), left temporal cortex (n=4) and dentate nucleus (n=1). In only 2 lesions (thalamus and dentate nucleus), hypometabolic foci were consistently related to signal change on MRI. SPM analysis revealed significantly decreased area in bilateral thalamus and left temporal cortex. F-18 FDG PET revealed significant hypometabolism in bilateral thalamus and left temporal cortex in adult patients with NF, and it might be helpful in understanding developmental abnormality of NF.

    Prominent ears are relatively frequent. Decreased self-esteem, increased anxiety, behavioral problems and social avoidance may result from disfigurement. In modern medicine it is becoming increasingly important to measure the benefit of surgical intervention by its impact on the patient's Quality of Life (QOL). Our study was performed in a retrospective manner at our institution including 40 adult patients with prominent ears. The Glasgow Benefit Inventory (GBI), a reproducible, valid and responsive questionnaire, was the basis of the used inquiry for detecting the changes in HRQOL after otoplasty. We showed an improvement in GBI subscores after intervention. There was no difference in GBI subscores between men and women. The follow-up time as well as critical life event and chronic concomitant disease have no influence on the GBI results. Otoplasty has a positive impact on the HRQOL of adult patients with prominent ears. The importance of this benefit is not only of individual nature. In times of healthcare economization, an amelioration of QOL followed by increased productivity at work of the individual is an important argument to justify health care expenditures. We believe that otoplasty is an appropriate therapy for selected adult patients burdened by prominent ears.

    Findings of magnetic resonance imaging (MRI) of the brain were retrospectively reviewed in 100 consecutive pediatric patients with epilepsy in relation to the type of epilepsy and prognosis. There were 65 boys and 35 girls, ranging in age from 3 months to 25 years. Among 100 patients, 67 (a total of 102 lesions) showed abnormal findings on MRI. Morphological abnormalities, including ventricular enlargement, atrophy and malformation, were seen in 54 patients. Periventricular (n=14), frontal (n=3), temporal (n=8) and occipital (n=7) areas were of high signal intensity on T2-weighted images. According to the type of epilepsy, MRI abnormality was seen in 34 (61%) of 56 patients with partial seizures and 33 (76%) of 44 patients with generalized seizures. When associated with cerebral palsy and mental retardation, the incidence of MRI abnormality was high. There was no sigificant correlation between MRI findings and prognosis. (N.K.).

    Background Hypertension is one of the recognized risk factors of cardiovascular diseases in adult diabetic patients. High prevalence of suboptimal blood pressure (BP) control has been well documented in the majority of studies assessing BP control in diabetic patients in sub-Saharan Africa. In Uganda, there is a dearth of similar studies. This study evaluated the prevalence and correlates of suboptimal BP control in an adult diabetic population in Uganda. Patients and methods This was a cross-sectional study that enrolled 425 eligible ambulatory adult diabetic patients attending three urban diabetic outpatient clinics over 11 months. Data about their sociodemographic characteristics and clinical history were collected using pre-tested questionnaires. Suboptimal BP control was defined according to the 2015 American Diabetes Association standards of diabetes care guideline as BP levels ≥140/90 mmHg. Results The mean age of the study participants was 52.2±14.4 years, with the majority being females (283, 66.9%). Suboptimal BP control was documented in 192 (45.3%) study participants and was independently associated with the study site (private hospitals; odds ratio 2.01, 95% confidence interval 1.18–3.43, P=0.01) and use of statin therapy (odds ratio 0.5, 95% confidence interval 0.26–0.96, P=0.037). Conclusion Suboptimal BP control was highly prevalent in this study population. Strategies to improve optimal BP control, especially in the private hospitals, and the use of statin therapy should be encouraged in adult diabetic patients.

    Full Text Available "nd anemia in our country. Blood transfusion is the continual treatment of this disease. But transfusion causes a serious side effect which is iron overload in vital organs such as the heart, liver and the endocrine system. Accumulated iron in these organs may cause high risk secondary problems which threaten the patients' life. Early assessment of the iron overload in vital organs and applying for early treatment can be beneficial for increasing life quality in these patients. Assessment of cardiac and hepatic iron overload using MRI T2 technique and comparing it with serum ferritin level was the goal of this study. "nMaterials and Methods: The referred thalassaemic patients to Zafar adult thalassaemia clinic were the population of this study. Serum ferritin test was carried out for all these patients. Cardiac and hepatic iron overload assessment of these patients was performed in Noor medical imaging center using MRI T2 technique. The iron overload results of all patients were classified as normal, mild, moderate and severe. We compared them with the patients’ clinical parameters, especially the serum ferritin level. Results were analyzed by SPSS software. "nResults: 700 adult patients with the mean age of 25.76 (SD±10.4 were studied in this research project. There were 360 males (51.4% and 340 (48.6% females enrolled in this study. Among them, there were 502 (71.7% major thalassaemia, 158 (22.6% intermediate thalassaemia, 7 alpha thalassaemia, 9 sickle cell anemia and 10 hemochromatosis patients. The mean of serum ferritin level was 2327.6 mg/dl (SD±2095.8. Classified results of cardiac iron overload assessment were normal in 366 (66.5% patients, mild in 44 (8% patients, moderate in 64 (11.6% patients, and severe in 76 (13.8%patients. The classified results of hepatic iron overload assessment were: normal in 122 (22.2% patients, mild in 137 (25% patients, moderate in 235 (42.8% patients and severe in 55 (10% patients.

    Full Text Available Las muertes súbitas por tumores intracraneales no diagnosticados en vida son muy raras. En el presente artículo se presenta el caso de un paciente joven que es hallado muerto durante el sueño. Como único antecedente de interés destaca la presencia desde la infancia de crisis epilépticas de difícil control medicamentoso. Las pruebas de imagen no habían mostrado en vida alteraciones reseñables. En la autopsia se evidencia un tumor de 0,5 x 1 cm en la corteza cerebral del lóbulo parietal izquierdo, sin efecto masa. A la vista de los hallazgos del estudio histopatológico e inmunohistoquímico se realiza el diagnóstico de tumor disembrioplástico neuroepitelial (TDN simple. Se establece como causa de la muerte el trastorno epiléptico orgánico secundario al tumor. El TDN es un tumor cerebral de muy baja frecuencia (0,2-1% de los tumores cerebrales y normalmente se asocia a crisis epilépticas fármaco-resistentes. Este caso demuestra que ante una muerte súbita e inexplicada asociada a epilepsia es fundamental la realización de una autopsia médico-legal a fin de reconocer la causa y los factores de riesgo relacionados con la epilepsia y la muerte.Sudden deaths due to intracranial tumors that have not been diagnosed in life are very rare. In this paper we present the case of a young patien
