Objective We describe the clinical, electroencephalograph^ and neuroimaging findings of older patients with typical absence status epilepticus (ASE). Methods This investigation was a retrospective analysis of prospectively collected consecutive patients between January 2011 and October 2021. All patients ≥60 years with impairment of awareness and continuous generalized, rhythmic, synchronous and symmetric epileptiform discharges and normal background on video-electroencephalogram (vEEG) were included. Results Six patients were identified with a diagnosis of typical ASE. The mean age was 67 years. Five could be classified as idiopathic generalized epilepsy (IGE) though two had been erroneously categorized as cryptogenic focal epilepsy (FE). In one, the episode of ASE was thought to represent the beginning of late-onset IGE (de novo late-onset typical ASE). In all cases, ASE was controlled within the first 24 hours. Significance Typical ASE is a rare cause of confusion in the elderly population requiring urgent vEEG evaluation. It most frequently represents reactivation of a previous IGE, in effect related to patients with epilepsy with onset in childhood or adolescence, not previously diagnosed or treated, representing rather the debut of (de novo) late-onset IGE.

We describe the pathophysiological consequences and long-term neurological outcome of a patient with acute brain injury (ABI) in whom intracortical electroencephalography (iEEG) captured an episode of prolonged focal non-convulsive status epilepticus (NCSE) that remained undetectable on scalp electroencephalography. A 53-year-old right-handed woman was admitted to hospital due to a large frontal left intraparenchymal hematoma. Over two and a half days, we captured recurrent non-convulsive electrographic and electroclinical seizures compatible with the diagnosis of intracortical focal NCSE. The patient remained sedated and a burst-suppression pattern was obtained. We also performed invasive brain multimodality monitoring including iEEG and measurements of intracranial pressure (ICP), partial brain tissue oxygenation (PbtO2) and brain temperature. During non-convulsive electrographic and electroclinical seizures, the values of PbtO2 decreased and those of ICP increased. Six months later, brain MRI revealed encephalomalacia localized to the left paramedial fronto-basal region. The neuropsychological assessment carried out one year after the injury showed scores below average in verbal learning memory, motor dexterity and executive functions. In summary, iEEG is a feasible innovative invasive technique that may be used to record non-convulsive electrographic and electroclinical seizures which remain invisible on the surface. Intracortical focal NCSE causes metabolic changes such as reduced brain oxygenation and an increase in ICP that can further damage previously compromised brain tissue.

Motor epilepsia partialis continua (EPC) is a frequent and widely described variant of simple focal motor status epilepticus. However, lingual EPC is an unusual epileptic condition. We present a case of lingual EPC secondary to low-grade glioma in which the EEG and neuroimaging features were particularly remarkable. The video-EEG showed lateralized periodic discharges with superimposed rhythmic activity and frequent recurrent focal epileptic seizures. Moreover, brain magnetic resonance imaging showed a right temporo-insular cortico-subcortical lesion which was hyperintense on FLAIR, suggestive of low-grade glioma. In addition, diffusion-weighted imaging and arterial spin labelling series showed restricted diffusion in the right temporo-insular and parietal cortex and increased cerebral flow, respectively. All these findings are in keeping with changes related to persistent focal status epilepticus. Finally, we review the literature and discuss the differential diagnosis of this rare epileptic entity.

The research has to main objectives: design a voice app (to work with emotional intelligence using a spoken test), as an alternative tool (as a help to a psychologist), that offers the possibility to have a better approach to students from “UT Tehuacán”; using Alexa skill kit to develop the tool. This voice app will ask a series questions to students as part of different psychologist test to detect early emotional patterns. The main goal is to understand how emotions work within students during day, and how to process them in a better way; this way the student can have information to deal to their feelings more efficiently and fulfil their personal goals. This information, will be stored by the app in Amazon Web Service AWS, and it also will be analysed by a backend service; this service will get data to make charts. The research design is transversal, because the data will be obtained in a single moment; it is also applicative due to it seeks to apply acquired knowledge to solve a situation, because it has as objective to find one or more variables in a population; in this case (detect early emotional patterns). In order to support the psycho-pedagogy department and the different educative programs to know possible problems students may have, and find if those problems can be a reason to quit school. For this reason this project can be use as a tool to make decisions.

Background Lung transplantation (LT) requires complex multidisciplinary organization and constitutes a therapeutic option and a life-saving procedure. Although the number of lung recipients continues to increase, neurological complications and death rates following lung transplantation are still higher than desirable. Purpose This study aims to analyse the neuroimaging findings in a cohort of adult patients with LT. Material and Methods A retrospective cohort study of all lung transplant recipients (344 patients: 205 men and 139 women) at a single institution from January 2011 to January 2020. The collected data included demographic features, clinical data and evaluation of the imaging findings. We also recorded the date of neurological complication(s) and the underlying disease motivating lung transplantation. Results We found an elevated rate of neuroimaging findings in patients following LT with 32.6% of positive studies. In our cohort, the average time after LT to a neurological complication was 4.9 months post-transplant. Encephalopathy, critical illness polyneuropathy and stroke, in that order, were the most frequent neurological complications. Structural abnormalities in brain imaging were more often detected using MRI than CT for indications of encephalopathy and seizures. Conclusions LT recipients constitute an especially vulnerable group that needs close surveillance, mainly during the early post-transplant period.

espanolLa lactancia materna (LM) tiene beneficios en la salud del binomio madre-hijo. El abandono y las barreras para realizar la practica de amamantar se relacionan con cuestiones biologicas, ambientales, culturales, sociales e individuales, entre otras. Todas ellas tienen influencia del conocimiento y actitudes que se adquiere durante la vida. La poblacion universitaria, es una generacion de adultos que forman un criterio integral sobre LM en funcion de la dinamica social. El objetivo del presente trabajo fue analizar el nivel de conocimiento y las actitudes de los estudiantes universitarios respecto a los beneficios de la lactancia materna en la salud. Se observo bajo nivel de conocimiento entre la poblacion universitaria sobre aspectos de importancia tales como, la duracion de la LM exclusiva, la reduccion del riesgo en el desarrollo de obesidad, infecciones de oido, diarrea o alergias alimentarias, especialmente en estudiantes que no fueron del area de la salud. Respecto a las actitudes, se identifico una alta aceptacion social de la practica de la LM. Sin embargo, los estudiantes consideran a la alimentacion con formula como una opcion mas practica. Es necesario realizar investigaciones que integren diversos sectores de la sociedad que permitan explicar los cambios en acciones y comportamientos hacia la LM. EnglishBreastfeeding (BF) has health benefits for the mother-child dyad. Abandonment and barriers to breastfeeding are related to factors at different levels that include biological, environmental, cultural, social, individual issues, among others. All of them are shaped by the knowledge and attitude that are acquired during life. The university population is a generation of adults who develop a comprehensive criterion on BF based on social dynamics. The objective of the present work was to analyze the level of knowledge and attitudes that university students have regarding the health benefits of BF. It was observed a low level of the knowledge about relevant aspects such as the duration of exclusive BF, the risk reduction in the development of obesity, ear infections, diarrhea or food allergies. Regarding attitude, a high level of social acceptance of the BF practice was identified. However, formula feeding is considered a more practical option. It is necessary to carry out further research that integrates various sectors of society that allow explaining the changes in actions and behaviors towards BF.

The exact pathophysiology of stimulus-induced rhythmic, periodic, or ictal discharges (SIRPIDs) remains unknown. The aim of this report is to describe the case of a patient that suffered from a vertebrobasilar stroke in whom asymmetric SIRPIDs due to a large right thalamic and mesencephalic infarction were observed. This case can provide some data that allows us to understand the mechanisms that potentially could be implicated in the origin of this fascinating electroencephalographic phenomenon.

We describe the case of an elderly woman with an episode of ambulatory de novo absence status epilepticus of late onset (DNASLO) after oral treatment with cefuroxime. A high level of suspicion of DNASLO in cases of unexplained confusion in adults or elderly subjects taking cephalosporins is essential to prompt an emergency EEG and, in turn, rapidly achieve an appropriate diagnosis and enable optimal treatment.

Introduction Metaldehyde self-poisoning in adults is uncommon and, to the best of our knowledge, an episode of super-refractory nonconvulsive status epilepticus (sr-NCSE) following an suicide attempt has not been previously demonstrated. Case report A 68-year-old woman was admitted to our Intensive Care Unit (ICU) in coma. On neurologic examination, the pupils were reactive, brainstem reflexes were present and plantar responses were flexor bilaterally. Routine laboratory tests were unremarkable. Arterial blood gas analysis revealed a mixed acidosis. A computed tomography (CT) scan of the brain and angio-CT were normal. The family confirmed that the patient had had suicidal ideation, and they had discovered a bag of slug killer (metaldehyde 5%) in her room. Two hours after the admission at the ICU, her neurological state remained unchanged. Sedation with intravenous propofol and antiepileptic therapy with levetiracetam (1000 mg/24 h) were started. The next day, propofol infusion was stopped but the level of consciousness of the patient did not improve. A video-electroencephalograhy (v-EEG) showed continuous generalized paroxysms of spike-wave and sharp-slow wave complexes compatible with the diagnosis of generalized NCSE. On day 3, the episode of NCSE was controlled. Finally, 15 days after ICU admission she was discharged with a normal neurological examination. Conclusion This clinical case highlights that in comatose patients as consequence of metaldehyde poisoning, a v-EEG evaluation should be perform in order to rule out the existence of NCSE.

Background. Subclinical seizures are ictal electrographic discharges lacking signs of clinical seizures, behavioural alteration or subjective symptoms. The diagnosis and detection of this type of non-convulsive seizures remain challenging, and information is scarce regarding this electroclinical picture in subjects with gliomas. The aim of this report is to describe two patients with gliomas who, after treatment with surgery and radiotherapy, exhibited subclinical seizures on video-EEG monitoring, as a manifestation of recurrence or progression of their brain tumour. Methods. Case report and video-EEG monitoring analysis. Results. Two patients with gliomas were admitted to our neurosurgical unit after a generalized tonic-clonic seizure. Brain MRI revealed a recurrence of their tumour. The use of video-EEG monitoring allowed the detection and characterization of subclinical seizures in both patients that otherwise would have gone undetected. In both cases, subclinical seizures arose from the frontal lobe and were not associated with motor manifestations or subjective symptoms. Conclusions. We emphasize that the existence of subclinical seizures in patients with gliomas is likely to be underestimated, and can occur in advanced progressive tumours. It is important to carry out continuous video-EEG monitoring in brain tumour patients who have had recent clinical seizures in order to be able to detect subclinical seizures and make appropriate diagnosis.

We retrospectively analysed the clinical characteristics, electroencephalogram (EEG) records, brain magnetic resonance imaging (MRI) scans, antiepileptic therapy and prognosis of a case series with ambulatory non-convulsive status epilepticus (NCSE) which evolved into a malignant form (mNCSE). mNCSE was defined as NCSE that continues or recurs five days or more after the onset of general anaesthesia, including those cases where NCSE recurs upon reduction or withdrawal of anaesthetic therapy. Four women and two men were studied. The mean age was 42.8 years (range: 19-63 years). Two of six patients had a previous diagnosis of epilepsy. Four patients died. Two patients had a good outcome with return to consciousness and activities of daily life, and one of these subjects developed temporal lobe epilepsy. In four patients, the cause of mNCSE was encephalitis. Clinical presentation was complex partial status epilepticus (CPSE) in three patients and generalised NCSE (GNCSE) in the other three. Two of the latter had encephalitis and one was diagnosed with progressive myoclonus epilepsy (PME) of Lafora type. The mean duration of the NCSE episode was 47.5 days (range: 9-139 days; SD: 53.1). In three patients, continuous or rhythmic focal epileptiform discharges were the EEG pattern at onset. In the other three, continuous rhythmic generalised spike-wave, polyspike-wave or sharp slow-wave complexes were observed. Antiepileptic treatment was heterogeneous and patients were treated with an average of 6.0 AEDs (range: 3-10; SD: 3.0). In summary, mNCSE is a severe epileptic condition that occurs often in the context of encephalitis or pre-existing epilepsy. Both CPSE and GNCSE may occur. Although high mortality is associated with mNCSE, some patients may survive with normal or good recovery.

Background. Status epilepticus, particularly non-convulsive status epilepticus (NCSE), is a frequent complication in patients with altered renal function receiving treatment with intravenous cefepime. To the best of our knowledge, we report the first case, illustrated by video-EEG, of a critically ill patient receiving treatment with cefepime who developed an episode of confirmed symptomatic myoclonic status epilepticus (MSE) . Methods. Case report and video-EEG. Results. A 60-year-old man, who had received a liver transplant due to alcoholic cirrhosis one year ago, was admitted to our intensive care unit due to septic shock. Computed tomography revealed a prostatic abscess as cause of his sepsis. On Day 27, a respiratory infection due to Pseudomona aeruginosa was diagnosed, and treatment with intravenous cefepime (2 g/8 hours) was initiated. On Day 32, his mental status deteriorated and he developed inattention, a reduced level of consciousness, and multifocal and generalised continuous myoclonic jerks. A video-EEG study was compatible with the diagnosis of symptomatic MSE. On Day 35, cefepime was stopped and general anaesthesia with midazolam was started in order to achieve a faster clinical improvement. We used the BIS-Vista™ monitor to guide general anaesthesia and detect potential episodes of NCSE. On Day 40, an EEG confirmed the existence of moderate diffuse encephalopathy. Finally, the patient died as a consequence of severe heart failure . Conclusions. Cefepime may be a cause of MSE in non-anoxic comatose patients. Clinicians should be aware of this possibility when evaluating comatose patients on cephalosporin therapy in order to establish a correct diagnostic approach and accurate prognosis.

We describe the case of a 69-year-old woman admitted to our intensive care unit (ICU) after 20 minutes of resuscitation from acute cardiopulmonary arrest. The patient developed a stimulus-sensitive postanoxic myoclonus in the following hours. The electroencephalogram (EEG) showed diffuse bursts of sharp activity against a completely suppressed background. This case report highlights the importance of carrying out a protocol of multiple and multimodal sensory stimulation when recording an EEG in comatose patients admitted to the ICU.

Compartment syndromes and ischemic contractures after ankle fractures are exceedingly rare. We report a case in which a Weber type-C ankle fracture resulted in an unrecognized compartment syndrome and ischemic contracture of deep posterior compartment of the leg. Six weeks after injury, the patient had an obvious deformity and clawing of the toes. The deformities were corrected by lengthening the flexor hallucis longus and the flexor digitorum longus. Full correction of all clawed toes was evident. A deep posterior compartment syndrome may follow an ankle fracture and should be considered in any patient with unrelenting pain in the immediate postoperative period.

Purpose to describe the characteristics of the color density spectral array (CDSA) of bilateral bispectral index (b-BIS) monitoring system in patients with comatose nonconvulsive status epilepticus (NCSE). We hypothesized that CDSA could be helpful for monitoring NCSE in critically subjects if continuous EEG (cEEG) is not available. Methods we retrospectively analyzed comatose patients admitted to our neurological intensive care unit (NICU) from 2011 to 2014 with a diagnosis of definitive NCSE that underwent b-BIS monitoring for at least 24h to guide anesthetic sedation. Clinical, electroencephalography and neuroimaging findings were analyzed. Moreover, all parameters from the b-BIS data including the CDSA were reviewed during periods of NCSE (NCSE pattern) and profound sedation (sedation pattern). Results 15 NCSE patients were included. The delay from the diagnosis of NCSE to the onset of b-BIS monitoring was 8 (0.5–31)h and total time of b-BIS monitoring 7.8±6.5 days. CDSA during NCSE pattern was characterized by continuous or intermittent red and dark red tones, spectral edge frequency (SEF) in the delta-theta range, with or without asymmetry and BIS number trend with significant variability. In contrast, CDSA during sedation revealed predominance of orange, yellow, green and occasionally blue tones, SEF in the alpha-beta range, absence of asymmetry and stability of BIS number. Conclusions b-BIS monitoring system and, in particular, CDSA used by nonexpert NICU personnel may be helpful to follow-up episodes of NCSE, to detect recurrences of nonconvulsive seizures (NCSzs), and to monitor profound anesthetic therapy in comatose patients when cEEG is not available.

We report the case of a patient with an extensive right cerebral hematoma complicated by focal nonconvulsive status epilepticus (NCSE) in whom the use of the new bilateral BIS-Vista™ monitor was helpful in managing profound sedation and antiepileptic treatment in the absence of continuous EEG monitoring (CEEG). The analysis of color density spectral array (CDSA) showed stereotyped changes indicative of recurrent focal nonconvulsive seizures (NCSz) and NCSE. We noted a close correlation between NCSz and BIS value changes. EEGs during working hours always confirmed the persistence of focal NCSE. After several days of sedation, CDSA disclosed a gradual resolution of NCSE that was also confirmed by electroencephalography. The patient died of cardiorespiratory complications a few days later.
