Consenso Delphi EPICON: recomendaciones sobre el manejo adecuado del cambio a acetato de eslicarbazepina en epilepsia / EPICON consensus: recommendations for proper management of switching to eslicarbazepine acetate in epilepsy

INTRODUCCIÓN: El objetivo del proyecto EPICON es desarrollar una serie de recomendaciones sobre la forma adecuada de realizar el cambio de carbamazepina (CBZ) y oxcarbazepina (OXC) a acetato de eslicarbazepina (ESL) en determinados pacientes con epilepsia. MÉTODOS: Un comité coordinador preparó un cuestionario con 56 preguntas en relación con el cambio de CBZ u OXC a ESL en la práctica clínica (metodología y situaciones del cambio). Posteriormente, se consultó a 54 expertos en epilepsia con el empleo de metodología Delphi (2 rondas de consulta). Se definió un consenso en acuerdo o desacuerdo si las respuestas para el ítem estudiado alcanzaban una mediana ≥ 7 o ≤ 3, respectivamente, y un rango intercuartílico relativo ≤ 0,40. Se analizaron los resultados y se formularon las conclusiones. RESULTADOS: Las recomendaciones fundamentales fueron: el cambio de CBZ a ESL debe ser realizado en 1-3 semanas, con una equivalencia de dosis CBZ:ESL de 1:1.3, siendo recomendado en pacientes con olvidos de medicación, trabajos por turnos, polimedicados, problemas cognitivos, osteoporosis-osteopenia severa, dislipidemia o enfermedad hepática (ausencia de fallo hepático grave), así como en varones con disfunción eréctil causada por CBZ. El cambio de OXC a ESL puede realizarse de un día para otro con una equivalencia de dosis 1:1 y es recomendado en pacientes con olvidos de medicación, trabajos por turnos, polimedicados o problemas cognitivos. Se desaconsejó el cambio en caso de rash con CBZ u OXC. CONCLUSIÓN: El proyecto EPICON proporciona algunas recomendaciones sobre el manejo clínico del cambio de CBZ u OXC a ESL, mediante el empleo de la metodología Delphi

INTRODUCTION: The objective of the EPICON Project is to develop a set of recommendations on how to adequately switch from carbamazepine (CBZ) and oxcarbazepine (OXC) to eslicarbazepine acetate (ESL) in some patients with epilepsy. METHODS: A steering committee drafted a questionnaire of 56 questions regarding the transition from CBZ or OXC to ESL in clinical practice (methodology and change situation). The questionnaire was then distributed to 54 epilepsy experts in 2 rounds using the Delphi method. An agreement/disagreement consensus was defined when a median ≥ 7 points or ≤ 3 was achieved, respectively, and a relative interquartile range ≤ 0.40. We analysed the results obtained to reach our conclusions. RESULTS: Our main recommendations were the following: switching from CBZ to ESL must be carried out over a period of 1 to 3 weeks with a CBZ:ESL dose ratio of 1:1.3 and is recommended for patients who frequently forget to take their medication, those who work rotating shifts, polymedicated patients, subjects with cognitive problems, severe osteoporosis-osteopaenia, dyslipidaemia, or liver disease other than acute liver failure, as well as for men with erectile dysfunction caused by CBZ. The transition from OXC to ESL can take place overnight with an OXC:ESL dose ratio of 1:1 and it is recommended for patients who frequently forget to take their medication, those who work rotating shifts, polymedicated patients, or those with cognitive problems. The transition was not recommended for patients with prior rash due to CBZ or OXC use. CONCLUSION: The EPICON Project offers a set of recommendations about the clinical management of switching from CBZ or OXC to ESL, using the Delphi method

Occurrence of chlorinated volatile organic compounds (VOCs) in a sanitary sewer system: Implications for assessing vapor intrusion alternative pathways.

Sewer systems have been recently recognized as potentially important exposure pathways to consider during vapor intrusion assessments; however, this pathway has not been well-characterized and there is need for additional information about the occurrence of volatile organic compounds (VOCs) in sewer systems. This paper reports the results of sewer gas sampling conducted in a sanitary sewer over the years of 2014-2017. Sewer gas samples were collected and analyzed using several different techniques, including TO-15 (grab), TO-17 (passive), Radiello® (passive) and a novel continuous monitoring technique, the Autonomous Rugged Optical Multigas Analyzer (AROMA). The applicability of each of the different approaches used in this study is discussed in the context of investigating sanitary sewers as a vapor intrusion alternative pathway. The data confirmed that trichloroethylene (TCE) concentrations in sewer gas were detected adjacent to and extending hundreds of feet away from a previously defined vapor intrusion area, where TCE was a primary contaminant. TCE concentrations detected in sewer gas ranged from non-detect to 1600µg/m3. Temporal variability was observed in TCE concentrations over timescales that ranged from minutes to months to years at discrete sampling locations. Spatial variability in sewer gas concentrations was also observed throughout the study area. Temporal and spatial variability may be caused by groundwater contamination sources in the study area, as well as sewer gas transport mechanisms.

A study of thin film solid phase microextraction methods for analysis of fluorinated benzoic acids in seawater.

Fluorinated benzoic acids (FBAs) are frequently used as tracers by the oil industry to characterize petroleum reservoirs. The demand for fast, reliable, robust, and sensitive approaches to separate and quantify FBAs in produced water, both in laboratory and field conditions, has not been yet fully satisfied. In this study, for the first time, thin film solid phase microextraction (TF-SPME) is proposed as a versatile sample preparation tool for the determination of FBAs in produced water by pursing two different approaches. First, an automated high throughput TF-SPME method using solvent desorption for fast and simultaneous preparation of multiple samples prior to liquid chromatographic separation and high resolution mass spectrometric detection (LC-MS) of FBAs was demonstrated for routine laboratory analysis. This method was optimized in terms of extraction phase chemistry, sample pH and ionic strength, extraction/desorption times using two representative FBAs (4-FBA and 2,3,4,5-tetra FBA). It incorporates a relatively simple sample pretreatment involving pH adjustment prior to the TF-SPME, and obtained limits of quantification (LOQ) are at the 1.0ngmL(-1) level. Second, the applicability of TF-SPME for fast mass spectrometric (MS) determination of FBAs with omission of derivatization and gas chromatographic (GC) separation was proven. This second method consists of manual extractions of analytes from seawater samples with a thermally stable TF-SPME membrane and direct thermal desorption of the extracted FBAs to a MS via a thermal desorption unit (TDU). It was demonstrated that the TF-SPME extracts and thermally releases analytes quantitatively and with good reproducibility. This approach opens up the possibility for on-site measurements with portable analyzers.

Descripción de una serie de pacientes con diagnóstico de enfermedad priónica / Clinical and neuroimaging characteristics of 14 patients with prionopathy: A descriptive study

Introducción: Las prionopatías representan hasta el 62% de los casos de demencia rápidamente progresiva (DRP) en los que se alcanza un diagnóstico definitivo. La variabilidad de los síntomas y signos iniciales y las diferencias en su evolución dificultan el diagnóstico precoz. Métodos: Estudio retrospectivo en el que se incluye a pacientes con prionopatía probable o definitiva, que acudieron a la consulta de Neurología de nuestro centro durante el periodo 1999-2012. Se describen las características clínicas y los resultados de las exploraciones complementarias (proteína 14-3-3, EEG, RM, PET-FDG y análisis genético), con la finalidad de identificar qué marcadores permiten un diagnóstico precoz. Resultados: Se describe a 14 pacientes: 6 con enfermedad de Creutzfeldt-Jakob esporádica (ECJe) definitiva, 3 con ECJe probable, 4 con insomnio familiar fatal y uno con la nueva variante de la enfermedad de Creutzfeldt-Jakob. La mediana de edad al diagnóstico fue de 54 años y la mediana de supervivencia de 9,5 meses. El trastorno del ánimo fue el síntoma inicial más frecuente, seguido de inestabilidad de la marcha y deterioro cognitivo. La proteína 14-3-3 fue positiva en el líquido cefalorraquídeo en 7 de 11 pacientes y el EEG mostró signos típicos en 2 de 12 pacientes explorados. El estudio de neuroimagen mostró alteraciones en 13 de los 14 pacientes. Conclusiones: Además de la DRP, el trastorno conductual y de la marcha son síntomas iniciales frecuentes en las prionopatías. En nuestra serie, las pruebas complementarias más útiles para apoyar el diagnóstico fueron la RM y la PET-FDG

Introduction: Prionopathy is the cause of 62% of the rapidly progressive dementias (RPD) in which a definitive diagnosis is reached. The variability of symptoms and signs exhibited by the patients, as well as its different presentation, sometimes makes an early diagnosis difficult. Methods: Patients withdiagnosis of definite or probable prionopathy during the period 1999-2012 at our hospital were retrospectively reviewed.The clinical features and the results of the complementary tests (14-3-3 protein, EEG, MRI, FDG-PET, and genetic analysis) were evaluated in order to identify some factors that may enable an earlier diagnosis to be made. Results: A total of 14 patients are described: 6 with definite sporadic Creutzfeldt-Jakob (sCJD) disease, 3 with probable sCJD, 4 with fatal familial insomnia, and 1 with the new variant. The median age at diagnosis was 54 years old. The mean survival was 9.5 months. Mood disorder was the most common feature, followed by instability and cognitive impairment. 14-3-3 protein content in the cerebrospinal fluid was positive in 7 of 11 patients, and the EEG showed typical signs in 2 of 12 patients. Neuroimaging (FDG-PET, MRI) studies suggested the diagnosis in 13 of the 14 patients included. Conclusions: Most patients presenting with RPD suffer from a prion disease. In our series the most useful complementary tests were MRI and FDG-PET, being positive in 13 of the 14 patients studied

Identifying single molecular ions by resolved sideband measurements.

The masses of single molecular ions are nondestructively measured by cotrapping the ion of interest with a laser-cooled atomic ion, (40)Ca(+). Measurement of the resolved sidebands of a dipole forbidden transition on the atomic ion reveals the normal-mode frequencies of the two ion system. The mass of two molecular ions, (40)CaH(+) and (40)Ca(16)O(+), are then determined from the normal-mode frequencies. Isotopes of Ca(+) are used to determine the effects of stray electric fields on the normal mode measurement. The future use of resolved sideband experiments for molecular spectroscopy is also discussed.

The np Rydberg series of boron monohydride: l-uncoupling and its evolution for intermediate principal quantum numbers n = 4 to n = 11.

Using optical-optical-optical triple-resonance spectroscopy, we assign rotational levels with N = 0-5 in the vibrationless, lower-n, p Rydberg states of (11)BH. We apply the Hill and Van Vleck formulation for energy levels with l = 1 in a Hund's case intermediate between (b) and (d) to gauge the energy separating (1)Π and (1)Σ(+) states with zero rotation for n = 4-11. This energy difference, A(l, ξ), represents the strength of the coupling, ξ, between the electron orbital angular momentum, l, and the internuclear axis, which determines the Λ-splitting constant, q(0). The np series exhibits a large q(0) that increases monotonically with n to reach a magnitude similar to the rotational constant, B(0), by n = 9. For higher principal quantum numbers, Λ ceases to be a good quantum number, and l-uncoupling becomes virtually complete for n > 10.

The np Rydberg series of boron monohydride: l-uncoupling and Rydberg electron interactions with the rovibrational motion of the ion core.

A simple two-channel quantum defect theory approach accounts for resonance positions in the np Rydberg series of (11)BH. The transition from Hund's case (b) to (d) in the interacting levels of this np series represents a fundamental example of electron orbital ⇔ cation core rotational coupling, and frame transformation theory offers a means to connect close-coupled electronically excited-state potentials and l-uncoupled Rydberg positions. This evolving interaction of the np Rydberg electron with the rotational and the vibrational motion of the (11)BH(+) core is formulated in terms of quantum defects, µ(λ)(v(+)).

[Video-EEG monitoring and simultaneous ECG for the differential diagnosis of transient consciousness disorders. A case report]. / Monitorización con vídeo-EEG y ECG simultáneo para el diagnóstico diferencial de trastornos de conciencia transitorios. A propósito de un caso.

We present the case of a 36 year-old woman, with history of transient consciousness disorders with vegetative state, interpreted as epileptic crises and treated with valproate for two years. After nine asymptomatic years, they reappeared associated with migraine, vomiting and some generalized convulsions. Electroencephalogram and cerebral magnetic resonance turned out normal, and treatment with zonisamide was started, without beneficial results. Later cardiological studies objectified a blockage of the left branch that coincided with dizziness. The study was completed with Video-EGG monitoring, where there was an episode that showed temporary right epileptiform activity, with a diagnosis established of focal epilepsy of unknown cause. At present, she remains asymptomatic with oxycarbazepine.

Se presenta el caso de una mujer de 36 años, con antecedentes de trastornos de conciencia transitorios con cortejo vegetativo en la adolescencia, interpretados como crisis epilépticas y tratados con ácido valproico durante dos años. Tras permanecer nueve años asintomática, reaparecieron asociados a migraña, vómitos y alguna convulsión generalizada. El electroencefalograma y la resonancia magnética cerebral resultaron normales e inició tratamiento con zonisamida, sin beneficio. Estudios cardiológicos posteriores objetivaron bloqueo de rama izquierda, que coincidía con mareo. Se completó el estudio mediante monitorización con vídeo-EEG, donde tuvo un episodio que evidenció actividad epileptiforme temporal derecha, estableciéndose el diagnóstico de epilepsia focal de causa desconocida. Actualmente, permanece asintomática con oxcarbacepina. La anamnesis es fundamental para diferenciar trastornos de conciencia transitorios, especialmente síncopes y crisis epilépticas, pero no siempre es suficiente. La monitorización con vídeo-EEG y registro simultáneo de electrocardiograma resulta muy útil para distinguirlos(AU)

Quality of life and treatment satisfaction in Spanish epilepsy patients on monotherapy with lamotrigine or valproic acid.

BACKGROUND: Patients suffering from epilepsy have an impaired health related quality of life (HRQoL) because of seizures and treatment adverse events. Epilepsy affects differently both genders, due to hormonal influence in women. The aim of this study is to assess the impact on HRQoL and treatment satisfaction in epilepsy patients treated with stable doses of lamotrigine and valproic acid. METHODS: Observational cohort prospective study was conducted in 18 Spanish neurology sites. Patients with clinically stable partial or generalized epilepsy, already receiving lamotrigine or valproic acid on monotherapy, were assessed in two visits: baseline and at 6 months. Socio-demographic and clinical variables were recorded at baseline; HRQoL (QOLIE-10) treatment satisfaction and women image self-perception were assessed at both visits. Impact on HRQoL was assessed in both treatment arms overall and in the women subgroup. RESULTS: A total of 107 patients were evaluated; 53 (14 men, 39 women) on lamotrigine and 54 (27 men, 27 women) on valproic acid. Mean (SD) age was 30.4 (9.1) years and mean (SD) time since epilepsy diagnosis was 8 (8.1) years. Mean (SD) QOLIE-10 score at baseline was 73.9 (15.7) points (76.6 and 71.4 for lamotrigine and valproic, respectively). At follow up, patients reported better HRQoL on both lamotrigine (78.8 points) (p<0.05) and on valproic (72.4 points) in comparison with baseline. Women's HRQoL at follow up was better on the lamotrigine arm compared with valproic acid: 78.8 (12.8) vs. 70.3 (15.9) (p<0.05). Women on the lamotrigine arm declared higher satisfaction with treatment and higher disagreement with the different statements referred to a negative image self-perception. CONCLUSIONS: Chronic patients with epilepsy already treated with lamotrigine slightly improved HRQoL at 6 month follow up, whereas no significant changes were observed in the valproic acid group. Lamotrigine impact on patients' HRQoL seems to be even more positive in the subgroup of women.

Vídeo-electroencefalografía: una necesidad / Video-electroencephalography: a necessity

El vídeo-EEG es una herramienta diagnóstica habitual. Los avances técnicos de la última década la han simplificado de tal modo que con poco más de un ordenador y una cámara de vídeo pueden conseguirse registros de calidad. Se requiere personal preparado para su ejecución e interpretación. Es muy útil para el diagnóstico de episodios paroxísticos, para la clasificación y caracterización de crisis epilépticas y para la cuantificación de crisis o grafoelementos epileptiformes. Dada la importancia de un diagnóstico exacto, certero, ante un episodio paroxístico, no cabe duda de que esta herramienta debe ser cada vez más asequible para evitar el mal trato a muchos enfermos neurológicos. A pesar del paso de los años, un 20-30% de pacientes diagnosticados de epilepsia no son realmente epilépticos, lo cual sigue siendo excesivo e inaceptable (AU)

The video-EEG is a common diagnostic tool nowadays. The technical achievements of the last decade have brought a simplification of the equipment required to obtain good quality recordings, with little more than a computer and a video camera being necessary. However, the medical and technical staff must be well trained to execute and interpret the study. It is very useful in the diagnosis of paroxysmal events, for the classification and characterization of epileptic seizures and to quantify epileptiform discharges. Due to the importance of a correct diagnosis to avoid mistreating many neurological patients, this tool should be accessible to clinicians. In spite of the advances of recent years, 20-30% of patients diagnosed with epilepsy are not really epileptic, a fact that it is excessive and unacceptable (AU)

Infrared spectra of C2H6, C2H4, C2H2, and CO2 aerosols potentially formed in Titan's atmosphere.

Pure and mixed aerosols of ethane, ethylene, acetylene and carbon dioxide were generated in a collisional cooling cell and characterized by Fourier transform infrared spectroscopy between 600 and 4000 cm(-1). Pure ethane, pure ethylene, and mixed ethane/ethylene initially form supercooled liquid droplets, which over time crystallize to their stable solid phases. These droplets are found to be long-lived (up to hours) for pure ethane and mixed ethane/ethylene, but short-lived (up to seconds) for pure ethylene. Acetylene and carbon dioxide form solid aerosol particles. Acetylene particles have a partially amorphous structure, while carbon dioxide particles are crystalline. The structure of the infrared bands of carbon dioxide is strongly determined by the particles' shape due to exciton coupling. The comparison of various mixed systems reveals that acetylene very efficiently induces heterogeneous crystallization. As reported earlier, the co-condensation of acetylene and carbon dioxide can lead to the formation of a metastable mixed crystalline phase. Our preliminary calculations show that this mixed phase has a monoclinic rather than the cubic structure proposed previously.

LC method for the therapeutic drug monitoring of lamotrigine: evaluation of the assay performance and validation of its application in the routine area.

An accurate and precise high-performance liquid chromatographic method using diode array detection for the determination of lamotrigine in human plasma has been developed and validated for use in pharmacokinetic studies. A validation strategy based on the accuracy profiles was used to select the most appropriate regression model and to determine the limits of quantitation as well as the concentration range. On the other hand, the present paper also shows this validation approach as a suitable tool to guaranty the quality of the results obtained by the use of the analytical validated methodology for plasma lamotrigine determination in a routine setting and to ensure the risk of obtaining the future measurements outside the previously fixed acceptance limits.

[Management of first epileptic seizure and status epilepticus in the emergency department]. / Manejo de la primera crisis epiléptica y del status en urgencias.

First epileptic seizure is a common reason for attending the emergency department. Its management is focused on diagnosis of the episode and on identification and treatment of the underlying cause. Occasionally, anti-epileptic treatment will be required. However, when the seizure is prolonged - a condition known as status epilepticus - it becomes a life-threatening process and requires immediate treatment. In this article, general advice and guidelines for the management of seizures and of status epilepticus in emergency departments is reviewed.

QOLIE-10 scores did not show any relationship with the type of seizures (p>0.05), either globally or for its different domains (cross-sectional validity). The mean score went from 73.9 (SD: 15.7) to 75.5 (SD: 14.9) between the two visits, equivalent to an increase of HRQoL of 1.6 (SD: 7.6) points (p=0.37) (longitudinal validity). A Cronbach's alpha coefficient of 0.811 was obtained (internal consistency). Interclass correlation coefficients were higher than 0.7 (reliability). In the overall score the effect size obtained was of 0.10 (responsiveness to change). CONCLUSIONS: The Spanish version of the QOLIE-10 has been shown to be feasible, valid, reliable and responsive to changes. The QOLIE-10 is a useful tool to measure HRQoL in usual clinical practice.

Manejo de la primera crisis epiléptica y del status en urgencias / Management of first epileptic seizure and status epilepticus in the emergency department

La primera crisis epiléptica es una causa frecuente de consulta en los servicios de urgencias. El manejo en urgencias se centra en el diagnóstico del episodio y en la identificación de la causa subyacente, y sólo ocasionalmente será necesario el inicio de un tratamiento antiepiléptico. Sin embargo, cuando la crisis es prolongada se convierte en una verdadera emergencia médica, el estatus epiléptico, y requiere un tratamiento inmediato.
