  • The patient who has congenital hypothyroidism and pseudohypoparathyroidism could have mental retardation even though adequate hormone treatment and cannot endure conventional dental treatment. In this case, general anesthesia is selected to administer effective dental treatment. But, there could be symptoms such as anemia, neuropathy, associated pituitary or adrenal hypofunction, cardiac failure even in euthyroid state. And, bradycardia, mental dullness, hypothermia, slow reflexes can appear in case of inadequate thyroid hormone replacement. Especially, macroglosssia, slow drug metabolism, exaggerated responses to anesthetic agents and decreased ventilatory responses could be problem during general anesthesia. The presentation of hypoparathyroidism also varies depending on the chronicity of the result of hypocalcemia. Muscle spasms/tetany, paresthesias, and seizures may occur in an acute onset. Chronic hypocalcaemia causes fatigue, muscle cramps, lethargy, personality changes, and cerebration defects.

  • Long-term electroencephalography (EEG) monitoring is time-consuming, and requires experts to interpret EEG signals to detect seizures in patients. In this paper, we propose a novel automated method called adaptive slope of wavelet coefficient counts over various thresholds (ASCOT) to classify patient episodes as seizure waveforms. ASCOT involves extracting the feature matrix by calculating the mean slope of wavelet coefficient counts over various thresholds in each frequency subband. We validated our method using our own database and a public database to avoid overtuning. The experimental results show that the proposed method achieved a reliable and promising accuracy in both our own database (98.93%) and the public database (99.78%). Finally, we evaluated the performance of the method considering various window sizes. In conclusion, the proposed method achieved a reliable seizure detection performance with a short-term window size. Therefore, our method can be utilized to interpret long-term EEG results and detect momentary seizure waveforms in diagnostic systems.

  • Purpose: This study investigated the need for information and social support in parents of children with epilepsy. Method: A total of 119 parents of children with epilepsy were recruited and asked to fill out questionnaires. Result: Of 119 parents, two-third reported that they received full and sufficient information about their child's disease and its management but one-third felt the information was insufficient and incomplete. Most parents (62.2%) felt at loss when their child had a seizure, either at home or at school. They wanted information on the causes of seizures, adequate steps deal with seizure and steps they should take to become adequate and supportive parents for their children. However, most parents were reluctant to disclose the disease or to receive support from outsiders. Conclusion: Regardless of the fact that most parents received sufficient information about the management of epilepsy, they felt at a loss when their child had a seizure attack. Therefore nurses should give specific instruction on seizure management and assess the needs of parents on a regular basis.

  • Epilepsy has continued to provide challenges to epileptologists, as a significant proportion of patients continue to suffer from seizures despite medical and surgical treatments. Deep brain stimulation (DBS) has emerged as a new therapeutic modality that has the potential to improve quality of life and occasionally be curative for patients with medically refractory epilepsy who are not surgical candidates. Several groups have used DBS in drug-resistant epilepsy cases for which resective surgery cannot be applied. The promising subcortical brain structures are anterior and centromedian nucleus of the thalamus, subthalamic nucleus, and other nuclei to treat epilepsy in light of previous clinical and experimental data. Recently two randomized trials of neurostimulation for controlling refractory epilepsy employed the strategies to stimulate electrodes placed on both anterior thalamic nuclei or near seizure foci in response to electroencephalographically detected epileptiform activity. However, the more large-scale, long-term clinical trials which elucidates optimal stimulation parameters, ideal selection criteria for epilepsy DBS should be performed before long. In order to continue to advance the frontier of this field, it is imperative to have a good grasp of the current body of knowledge.

  • Purpose: The purpose of this study was to identify the current status and needs in neonatal emergency training for nursing students in Korea and to obtain preliminary information to develop a simulation based educational program on neonatal emergency care for nursing students. Methods: Structured questionnaires were distributed to five hospitals and ten nursing schools during April and May, 2012. Data were collected from 59 nurses who worked in the nursery or Neonatal Intensive Care Units and 13 nursing educators who had specialized in pediatric nursing. Results: Most nurses (86.4%) reported that they had experienced an emergency situation with newborns. Most nursing educators (84.6%) claimed that more intensive training with newborns is needed for nursing students. In particular, training in neonatal resuscitation (72.2%), respiratory distress (59.7%), and neonatal seizures (18.1%) were highly recommended as simulation based training for nursing students. Conclusion: A significant need for neonatal emergency educational programs was found. More efforts should be made to provide nursing students with knowledge and skills for working with neonates. The findings of this survey will ultimately provide a basis for developing a simulation based educational program on neonatal emergency care for nursing students.

  • To investigate the significant indicators Improving the undisturbed memory in animal behavior, we employed several behavioral methods (learning, relearning in radial maze, and active avoidance) with ginseng components. Results showed that the repeated intranasal administration of $Rb_1$ and total saponins from Korean red ginseng induced direct effects on the brain mechanisms in rats, and improved the spatial memory during the learning, relearning and retention in the 12-arm radial maze test. The intranasal treatment of the total saponins also effectively improved the disturbed memory (amnesia) by pentylentetrazole, and simultaneously protected the brain by decreasing the severity of motor epileptic seizures. The intraperitonial administration of polysaccharide fraction of Korean red ginseng could improve avoidance behavior (amount of the total ecapes) in the active-avoidance test. In addition, local changes of the temperature and resistance of skin observed after Rb, administration were suggested to reflect some action of sympathetic nerve Key words Memory, intranasal administration, pentylenetetrazole, Korea red ginseng.

  • The EEG plays an important diagnostic role in epilepsy and provides supporting evidence of a seizure disorder as well as assisting with classification of seizures and epilepsy syndromes. There are a variety of electroclinical syndromes that are really defined by the EEG such as Lennox-Gastaut syndrome, benign rolandic epilepsy, childhood absence epilepsy, juvenile myoclonic epilepsy and also for localization purposes, it is vitally important especially for temporal lobe epilepsy. The sensitivity of first routine EEG in diagnosis of epilepsy has been known about 20-50%, but this proportion rises to 80-90% if sleep EEG and repetitive recording should be added. Convincing evidences suggest that the EEG may also provide useful prognostic information regarding seizure recurrence after a single unprovoked attack and following antiepileptic drug (AED) withdrawal. Moreover, patterns in the EEG make it possible to disclose an ictal feature of nonconvulsive status epilepticus, separate epileptic from other non-epileptic episodes and clarify the clues predictive of the cause of the encephalopathy (i.e., triphasic waves in metabolic encephalopathy). Therefore, regardless of its low sensitivity and other pitfalls, EEG should be considered not only in the situation of new onset episode such as a newly developed, unprovoked seizure or a condition manifesting decreased mentality from obscure origin, but also as a barometer of the long-term outcome following AED withdrawal.

  • Signals of the Electroencephalogram (EEG) can reflect the electrical background activity of the brain generated by the cerebral cortex nerve cells. This has been the mostly utilized signal, which helps in effective analysis of brain functions by supervised learning methods. In this paper, an approach for improving the accuracy of EEG signal classification is presented to detect epileptic seizures. Moreover, Independent Component Analysis (ICA) is incorporated as a preprocessing step and Short Time Fourier Transform (STFT) is used for denoising the signal adequately. Feature extraction of EEG signals is accomplished on the basis of three parameters namely, Standard Deviation, Correlation Dimension and Lyapunov Exponents. The Artificial Neural Network (ANN) is trained by incorporating Levenberg-Marquardt(LM) training algorithm into the backpropagation algorithm that results in high classification accuracy. Experimental results reveal that the methodology will improve the clinical service of the EEG recording and also provide better decision making in epileptic seizure detection than the existing techniques. The proposed EEG signal classification using feed forward Backpropagation Neural Network performs better than to the EEG signal classification using Adaptive Neuro Fuzzy Inference System (ANFIS) classifier in terms of accuracy, sensitivity, and specificity.

  • In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Liquid(NSCL) and Wonbang Woohwangchungsimwon Liquid(SCL), the effects of NSCL and SCL on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed a preventive effect of NSCL and SCL treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NSCL and SCL treatment. In contrast to what was seen with ATP, lipid peroxide were elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NSCL and SCL treatments. While NSCL and SCL had no effects on the hexobarbital-induced sleeping time, they showed sedative effect in rotarod and spontaneous activity test. NSCL and SCL prevented the seizures induced by electric shock and strychnine, but the effect of NSCL was less than that of SCL. Furthermore, NSCL and SCL showed anti-stress effect. Our findings suggest that the pharmacological profiles of NSCL on cerebral ischemia and central nervous system are similar to those of SCL.
