Ictal kissing: occurrence and etiology.
Ictal kissing is a rare semiological manifestation in patients with epilepsy. We tried to estimate its occurrence and characterize the underlying etiology. We retrospectively reviewed all video-EEG reports from Jefferson Comprehensive Epilepsy Center over a 12-year period (2004-2015) for the occurrence of the term kiss . We then searched the electronic database PubMed on September 21, 2016 using the following search terms in the English language: ictal OR seizure OR epilepsy AND kiss OR kissing . Relevant original studies were included. During the study period, 5133 patients were investigated in our epilepsy monitoring unit. One patient (0.02%) had one episode of documented ictal kissing. He had drug-resistant right mesial temporal lobe epilepsy. In total, five studies met the criteria for inclusion in the review. These studies described nine patients with drug-resistant focal epilepsy and ictal kissing behavior. Six out of ten patients with ictal kissing had hippocampal sclerosis. We add to the literature on ictal kissing by providing additional information on its frequency and etiology. The most common underlying etiology for ictal kissing is hippocampal sclerosis. However, this semiological ictal phenomenon is not pathognomonic for any etiology or localization
Semiological classification of psychogenic nonepileptic seizures.
PURPOSE: We classified patients with psychogenic nonepileptic seizures (PNESs) according to a newly proposed classification system. Then, we investigated the demographic and clinical differences between various classes of the patients.
METHODS: We retrospectively investigated all patients with PNESs admitted to the Jefferson Comprehensive Epilepsy Center from 2012 through 2016. We classified the patients into four distinct classes: patients with generalized motor seizures, patients with akinetic seizures, patients with focal motor seizures, and patients with seizures with subjective symptoms. All patients were interviewed by a neuropsychologist and were administered psychological assessment measures, including questions about PNES risk factors. For the statistical analyses, we compared patients who had generalized motor seizures with patients who had nonmotor seizures.
RESULTS: Sixty-three patients were studied. Thirty-five (55.6%) patients had generalized motor seizures, 14 (22.2%) had seizures with subjective symptoms, 12 (19%) had akinetic seizures, and two (3.2%) patients had focal motor seizures. Patients with generalized motor seizures (35 patients) demonstrated a trend for later age at onset (p=0.06), more frequently had a history of substance abuse (p=0.001), and more often had loss of responsiveness with their seizures (p=0.04) compared with patients who had nonmotor seizures (26 patients).
CONCLUSION: The recently proposed PNES classification system is useful and practical. This proposed classification of PNESs may address proper diagnosis and provide standardization across future studies. This may also potentially shed light on the etiologic understanding and management of various classes of patients affected with PNESs

Generation of Caustics and Spatial Rogue Waves from Nonlinear Instability
Caustics are natural phenomena in which nature concentrates the energy of
waves. Although, they are known mostly in optics, caustics are intrinsic to all
wave phenomena. For example, studies show that fluctuations in the profile of
an ocean floor can generate random caustics and focus the energy of tsunami
waves. Caustics share many similarities to rogue waves, as they both exhibit
heavy-tailed distribution, i.e. an overpopulation of large events. Linear
Schr\"odinger-type equations are usually used to explain the wave dynamics of
caustics. However, in that the wave amplitude increases dramatically in
caustics, nonlinearity is inevitable in many systems. In this Letter, we
investigate the effect of nonlinearity on the formation of optical caustics. We
show experimentally that, in contrast to linear systems, even small phase
fluctuations can generate strong caustics upon nonlinear propagation. We
simulated our experiment based on the nonlinear Schr\"odinger equation (NLSE)
with Kerr-type nonlinearity, which describes the wave dynamics not only in
optics, but also in some other physical systems such as oceans. Therefore, our
results may also aid our understanding of ocean phenomena.Comment: 5 pages, 4 figure
Pendekatan Pendidikan Multikultural pada Mata Pelajaran Sosiologi SMA Kelas XI
Tujuan penelitian ini adalah untuk menggambarkan penggunaan pendekatan pendidikan multikultural pada pelajaran Sosiologi SMA kelas XI. Penelitian ini merupakan penelitian kualitatif yang dilakukan di SMAN 4 Purworejo. Data dikumpulkan melalui metode pengamatan dan wawancara dengan guru Sosiologi SMAN 4 Purworejo. Hasil penelitian menunjukkan bahwa karakteristik Pendekatan Pendidikan multikultural yang dilakukan oleh guru sosiologi SMA menekankan pada tiga bentuk: optimalisasi peran rasionalitas bagi siswa, praktek dan pembiasaan perbedaan pendapat. Pendekatan ini tepat dilakukan dalam kegiatan pembelajaran pada materi kelompok sosial dalam masyarakat multikultural. Kendala dalam pelaksanaan pendekatan multikultural di SMA adalah, alokasi waktu pertemuan, konsentrasi siswa dalam menerima materi pelajaran yang berhubungan dengan multikultural, keterbatasan media pembelajaran yang digunakan saat pembelajaran serta minat siswa dalam belajar. Hal ini membuat guru bekerja ekstra untuk membuat variasi dalam pembelajaran agar kegiatan belajar mengajar dapat berhasil dengan baik.The objective of this article is to describe the use of multicultural education approach to the study of sociology for senior high school student class XI. This study is a qualitative study conducted in SMAN 4 Purworejo. Data were collected through a method of observation and interviews with teachers of Sociology. The results show that the characteristics of a multicultural approach to education implemented by high school sociology include three forms: teacher’s emphasis on the optimization of students’ rationality, practice and dissent habituation. This approach is appropriate for the learning activities on material of social groups in multicultural societies. Constraints in the implementation of a multicultural approach in high school include time allocation, student’s concentration, the limitations of instructional media used during the learning process, and finally the student’s interest in learning. This makes teachers work hard to make the variation in learning in order that teaching and learning activities can have good results
Efektifitas Biji Kelor (Moringa Oleifera Lamk) sebagai Koagulan Besi (Fe) dan Kalsium (Ca)
Research about coagulation of iron and calcium have been conducted using moringa (moringa oleifera Lamk) seed coagulant through the variation of the concentration of moringa seed and depositional time. Moringa seeds were used in this research that moringa seeds are old and dry. Compounds of moringa seeds that play role in the coagulation process of iron and calcium are proteins. This research was conducted to determine the optimum concentration of moringa seed and optimum deposition time on the process of coagulation using moringa seed coagulant in order to obtain the percentage decrease in the levels of iron and calcium. Variations in the concentration of moringa seeds were used in this research are 100, 200, 300, 400 and 500 ppm and the settling time is 30, 60, 90, 120 and 150 minutes. The results showed that the concentration of moringa seed and deposition time influenced in the process of coagulation of iron and calcium. In iron coagulation, obtained optimum concentration of 400 ppm moringa seeds and optimum settling time is 90 minutes. In these conditions the iron content decreased by 68.00 ppm or 66.95% from its initial level of 99.8 ppm. While the calcium coagulation, moringa seeds obtained optimum concentration of 500 ppm and optimum settling time of 120 minutes, which in this condition calcium levels decreased by 241 ppm or 49.00% of the initial concentration is 492 ppm
Local density of states of 1D Mott insulators and CDW states with a boundary
We determine the local density of states (LDOS) of one-dimensional
incommensurate charge density wave (CDW) states in the presence of a strong
impurity potential, which is modeled by a boundary. We find that the CDW gets
pinned at the impurity, which results in a singularity in the Fourier transform
of the LDOS at momentum 2k_F. At energies above the spin gap we observe
dispersing features associated with the spin and charge degrees of freedom
respectively. In the presence of an impurity magnetic field we observe the
formation of a bound state localized at the impurity. All of our results carry
over to the case of one dimensional Mott insulators by exchanging the roles of
spin and charge degrees of freedom. We discuss the implications of our result
for scanning tunneling microscopy experiments on spin-gap systems such as
two-leg ladder cuprates and 1D Mott insulators
Knowledge, Attitudes and Practice of Pharmacovigilance Among Health Care Professionals in Indonesia
Background: World Health Organization (WHO) defines pharmacovigilance (PV) as a science and activities related to detection, assessment, understanding and prevention of adverse effect or any other drug related problem. It aims to enhance patient care and patient safety in drug use. Although Indonesia has joined WHO International drug safety monitoring program since 1970s, the implementation is not applied effectively especially in developing country and there are poor contribution of health care professionals (HCPs) as an agent of the program. In this study, we assessed current knowledge, activities and practice of PV among HCPs in Indonesia. Methods: This is a preliminary survey using a questionnaire distributed among HCPs through health seminar and internet. The questionnaire consists of statement/question about knowledge(6), activities(6) and whether HCPs who encounter ADRs handle and report it correctly. If the respondents gave 80 % suitable answers in the knowledge or attitude sections, they were categorized as having “good” knowledge or attitude. We analyzed whether knowledge, attitude and other characteristic had any influence on the respodents PV practice. Results: We included 109 questionnaires from 118 distributed questionnaires. Most of the respondents were females (90 respondents, 82.6%), medical doctors (100 respondents, 91.7%), and were working in primary health care level. Good knowledge was found in 28 (25.7 %) of respondents, while good attitude towards PV were found in less than 20 % (18) of the respondents. Only 4 (3.7 %) of total respondents did a good pharmacovigilance practice. We found no significant association between level of knowledge, attitude and other factors to the poor pratice of PV. Conclusion: The knowledge, activities and practices of pharmacovigilance among HCPs in Indonesia were poor and requires a continuous socialization among HCPs in different level of care
