From Diagnosis to Resolution: A Case Study of Myxopapillary Ependymoma Survival.

Myxopapillary ependymoma (MPE) is a rare, slow-growing tumor that commonly arises in the lumbosacral region of the spinal cord, within the filum terminale and cauda equina. The frequent presentation of MPE is back, sacral, or leg pain. The tumor's size, site, and extension usually influence these symptoms. MPE is usually evaluated using magnetic resonance imaging (MRI) because of its superior soft tissue contrast. The best treatment modality is total surgical resection, which improves the long-term survival rate, with follow-up imaging recommended to ensure total resolution. Here, we present the case of a 29-year-old male who presented with symptoms suggestive of severe neurological impairment. An MRI scan revealed an intradural lesion arising from the cauda equina with peripheral and intrathecal haemorrhage, consistent with MPE. He was managed with laminectomy and microsurgical resection of the tumor, which achieved total resection. Postoperative follow-up found gradual improvement in his symptoms, and routine surveillance imaging confirmed the complete resolution of the tumor.

Incidence and pattern of neurological emergencies in Ramadan.

BACKGROUND: The impact of Ramadan fasting on various neurological emergencies remains relatively unexplored. This study aimed to clarify the incidence and pattern of the different neurological emergencies in Ramadan compared to Shaaban. METHODS: In this cross-sectional study, all adult patients attending the emergency room at two Egyptian centers with neurological emergencies during Shaaban and Ramadan were evaluated. Clinical, laboratory, and radiological assessments were made on an individual basis upon which the diagnosis of neurological disorder was made. IBM SPSS Version 25 was used to analyze the data. RESULTS: Seventy-twenty patients were included, 382 during Shaaban and 338 during Ramadan. Among causes of delirium, the frequency of dehydration was significantly higher, and the frequency of illicit drug abuse was significantly lower during Ramadan compared to Shaaban (P = 0.004, 0.030, respectively). The incidence of ICH was significantly reduced during Ramadan compared to Shaaban (10.8% vs 19.7%, P = 0.031). The incidence of cardioembolic strokes significantly increased during Ramadan than Shaaban (40.5% vs 26.4%, P = 0.014), whereas the incidence of small vessel disease (SVD) significantly decreased during Ramadan than Shaaban (21.6% vs. 42.1%, P < 0.001). The incidence of a single seizure was significantly higher in Ramadan than in Shaaban (69.4% vs. 34.6%, P = 0.007). The incidence of functional neurological disorders was significantly reduced in Ramadan than in Shaaban (P < 0.001). CONCLUSION: The incidence of delirium caused by illicit drug abuse, ICH, SVD, and functional neurological disorders declined during Ramadan, while the incidence of delirium triggered by dehydration, cardioembolic strokes, and a single seizure increased during Ramadan.

Safety and Effect on Intracranial Pressure of 3% Hypertonic Saline Bolus Via Peripheral Intravenous Catheter for Neurological Emergencies.

BACKGROUND: Elevated intracranial pressure (ICP) is a neurological emergency in patients with acute brain injuries. Such a state requires immediate and effective interventions to prevent potential neurological deterioration. Current clinical guidelines recommend hypertonic saline (HTS) and mannitol as first-line therapeutic agents. Notably, HTS is conventionally administered through central venous catheters (CVCs), which may introduce delays in treatment due to the complexities associated with CVC placement. These delays can critically affect patient outcomes, necessitating the exploration of more rapid therapeutic avenues. This study aimed to investigate the safety and effect on ICP of administering rapid boluses of 3% HTS via peripheral intravenous (PIV) catheters. METHODS: A retrospective cohort study was performed on patients admitted to Sisters of Saint Mary Health Saint Louis University Hospital from March 2019 to September 2022 who received at least one 3% HTS bolus via PIV at a rate of 999 mL/hour for neurological emergencies. Outcomes assessed included complications related to 3% HTS bolus and its effect on ICP. RESULTS: Of 216 3% HTS boluses administered in 124 patients, complications occurred in 8 administrations (3.7%). Pain at the injection site (4 administrations; 1.9%) and thrombophlebitis (3 administrations; 1.4%) were most common. The median ICP reduced by 6 mm Hg after 3% HTS bolus administration (p < 0.001). CONCLUSIONS: Rapid bolus administration of 3% HTS via PIV catheters presents itself as a relatively safe approach to treat neurological emergencies. Its implementation could provide an invaluable alternative to the traditional CVC-based administration, potentially minimizing CVC-associated complications and expediting life-saving interventions for patients with neurological emergencies, especially in the field and emergency department settings.

"Meet the patient" session: a strategy to teach medical students about autonomic dysfunction after spinal cord injury.

Dysregulation of the autonomic nervous system is an important long-term consequence of spinal cord injury (SCI). Yet, there is a scarcity of teaching resources about this topic for preclinical medical students. Given the association of SCI sequelae with emergency complications and mortality, it is imperative to equip medical students with the ability to recognize them. We designed a "Meet the Patient" (MTP) session with the primary goal to enhance student learning about SCI sequelae by interacting with patients and listening to real-life stories. The session primarily focused on recognizing triggers and symptoms of autonomic dysreflexia (AD) and discussing the loss of bowel and bladder control, while providing opportunities to learn more about living with SCI from patients' real-life experiences. During the MTP session, patients living with SCI discussed their experience with AD, neurogenic bowel and bladder, and spasticity, among other SCI sequelae. We evaluated the outcomes of the MTP session by assessing numerical performance in questions related to the session (post-session quiz and final exam) and students' satisfaction (post-session survey) in two subsequent academic years. The numerical performance in SCI-questions was high for both academic years (and higher than national average for the final exam question), indicating adequate acquisition of knowledge. Satisfaction with the session was high, with most students indicating that the session helped them consolidate their knowledge about the topic.

Sex Differences in Neurological Emergencies Presenting to Multiple Urban Level 1 Trauma Centers.

Previous studies have suggested that there are sex differences in the treatment and outcome of neurological emergencies; however, research identifying the role these sex differences play in the management of neurological emergencies is lacking. More knowledge of the way sex factors into the pathophysiology of neurological emergencies will be helpful in improving outcomes for these patients. The aim of this cross-sectional study was to assess the prevalence and management of neurological emergencies while evaluating sex differences in the diagnosis and treatment of these emergencies. We analyzed a cohort of 530 adult patients from four level 1 trauma centers over a period of 4 weeks who had a chief complaint of a neurological emergency, including seizures, cerebrovascular events, headache disorders, traumatic brain injuries, and central nervous system infections. Among patients with neurological emergencies, a significantly lower proportion of female patients underwent neurosurgery and were admitted to the intensive care unit compared to male patients, but there were no significant differences between sexes in the time of symptom onset, type of hospital transportation, amount of neuroimaging performed, admission rates, hospital length of stay, and disposition from the emergency department. Although female patients were more likely to have a chief complaint of headache compared to traumatic injuries in male patients, this was not statistically significant. A significantly higher proportion of female patients had health insurance coverage than male patients.

Pattern and determinants of outcomes of neurological emergencies admitted into children emergency ward in a tertiary hospital in Port Harcourt, Nigeria

Neurological emergencies are life-threatening central nervous system disorders, significantly contributing to childhood morbidity and mortality. The sequelae may be irreversible and may impact negatively on the quality of life of affected children and their families. This study identified the morbidity pattern and determinants of the outcomes of children with neurological emergencies in the Children Emergency Room (CHER) of the Rivers State University Teaching Hospital (RSUTH). Method: A 4-year retrospective study was carried out in the CHER. Data on demography, diagnosis and outcomes of children with neurological disorders were extracted from the records. Data analysed with SPSS 24 were expressed in percentages and frequency tables. Results: Of the 3040 children admitted in the CHER, 364(12%) aged 0-15 years had neurological emergencies, commoner among males (59.3%) and children aged less than five years (70.9%). Meningitis (40.2%) and febrile convulsion (28.2%) were the topmost diagnoses made. Raised intracranial pressure (17.4%) and head injuries (25.5%) were significantly more prevalent among children aged five years and above. The mortality rate was 61(16.8%) and more among adolescents (30.6%). All the mortalities took place within the first 48hours of admission especially among those with head injuries (46.5%) and perinatal asphyxia (95%), (p < 0.05). Conclusion: Meningitis and febrile convulsion were the commonest neurologic emergencies seen in this study. Mortality rate was high, especially in the first 48 hours of admission and mainly from perinatal asphyxia and head injuries. Education on the prevention and management of neurologic emergencies should be strengthened

Interventions to improve health literacy in Nigeria: systematic review of effectiveness and policy recommendations

Background: Health literacy plays a crucial role in enabling individuals to navigate and make informed decisions within the healthcare system. It encompasses the ability to understand, interpret, and act upon medical information and instructions, as well as the capacity to source and analyse relevant health information for preventive measures and self-care. This paper explores the interventions aimed at improving health literacy in Nigeria and synthesizes policy recommendations for the Nigerian government. Method: A systematic literature review based on the PRISMA methods was carried out to identify published interventions and reported effectiveness in the Nigerian population. A search strategy using key words health literacy and health interventions was executed in PubMed, Embase and African Index Medicus. A total of 268 records were screened for relevance and 18 were identified. Results: Of the 18 reports identified, 13 interventions were effective, 3 interventions had mixed results reporting effectiveness in some domains and ineffectiveness in other important domains, while 2 interventions were not effective. The nature of effectiveness in the interventions was based on the outcomes as reported in the identified studies. Conclusion: The health literacy situation in Nigeria provides a background into some of the challenges faced in achieving universal health coverage and promoting health in Nigeria. Low literacy rates, particularly in its many rural areas, the lack of functional, communicative, and critical health literacy competencies among many adults, as conceptualised in literature pose a significant obstacle to health literacy development in Nigeria. Many of the health literacy interventions have been effective to address various aspects of health literacy on a rather small scale. To comprehensively address the problem, collaborative efforts involving the government, healthcare professionals, non-governmental organisations, media, and the community are necessary.

The pattern of neurocritical disorders in multicenter in Khartoum State November 2020 to January 2021.

BACKGROUND: Neurocritical care is a growing subspecialty. It concerns with the management of life-threatening neurological disorders. There is limited information regarding epidemiological data, disease characteristics, variability of clinical care, and in-hospital mortality of neurocritical patients worldwide. OBJECTIVES: To study the pattern of neurocritical disorders in intensive care units. METHODOLOGY: This prospective observational study was conducted on neurocritical patients who were admitted to four intensive care units of major hospitals in Khartoum state during the period from November 2020 to January 2021. RESULTS: Seventy-two neurocritical patients were included in this study, 40 (55.6%) were males and 32(44.4%) were females. Twenty-three (31.9%) patients were with stroke, 12 (16.7%) with encephalitis, 9 (12.5%) with status epilepticus, 6 (8.3%) with Guillain Barre syndrome, and 4(5.6%) with Myasthenia Gravis (MG). Twenty-three patients (39.9%) needed mechanical ventilation (MV), which was the major indication for intensive care unit admission. CONCLUSION: Stroke was the dominant diagnostic pattern requiring intensive care unit admission. Mechanical ventilation was the major indication for admission. Establishing specialized neurocritical intensive care units is highly recommended.

Prognostication in Acute Neurological Emergencies.

BACKGROUND: For patients with acute, serious neurological conditions presenting to the emergency department (ED), prognostication is typically based on clinical experience, scoring systems and patient co-morbidities. Because estimating a poor prognosis influences caregiver decisions to withdraw life-sustaining therapy, we investigated the consistency of prognostication across a spectrum of neurology physicians. METHODS: Five acute neurological presentations (2 with large hemispheric infarction; 1 with brainstem infarction, 1 with lobar hemorrhage, and 1 with hypoxic-ischemic encephalopathy) were selected for a department-wide prognostication simulation exercise. All had presented to our tertiary care hospital's ED, where a poor outcome was predicted by the ED neurology team within 24 hours of onset. Relevant clinical, laboratory and imaging data available before ED prognostication were presented on a web-based platform to 120 providers blinded to the actual outcome. The provider was requested to rank-order, from most to least likely, the predicted 90-day modified Rankin Scale (mRS) score. To determine the accuracy of individual outcome predictions we compared the patient's the actual 90-day mRS score to highest ranked predicted mRS score. Additionally, the group's "weighted" outcomes, accounting for the entire spectrum of mRS scores ranked by all respondents, were compared to the actual outcome for each case. Consistency was compared between pre-specified provider roles: neurology trainees versus faculty; non-vascular versus vascular faculty. RESULTS: Responses ranged from 106-110 per case. Individual predictions were highly variable, with predictions matching the actual mRS scores in as low as 2% of respondents in one case and 95% in another case. However, as a group, the weighted outcome matched the actual mRS score in 3 of 5 cases (60%). There was no significant difference between subgroups based on expertise (stroke/neurocritical care versus other) or experience (faculty versus trainee) in 4 of 5 cases. CONCLUSION: Acute neuro-prognostication is highly variable and often inaccurate among neurology providers. Significant differences are not attributable to experience or subspecialty expertise. The mean outcome prediction from group of providers ("the wisdom of the crowd") may be superior to that of individual providers.

Non-COVID Neurological Emergencies: A Silent Killer Going Unnoticed during COVID-19 Pandemic.

Objective This study assesses the impact of coronavirus disease 2019 (COVID-19) on the pattern of neurological emergencies reaching a tertiary care center. Materials and Methods This is a retrospective and single center study involving 295 patients with neurological emergencies mainly including acute stroke, status epilepticus (SE), and tubercular meningitis visiting emergency department (ED) from January 1 to April 30, 2020 and divided into pre- and during lockdown, the latter starting from March 25 onward. The primary outcome was number of neurological emergencies visiting ED per week in both periods. Secondary outcomes included disease severity at admission, need for mechanical ventilation (MV), delay in hospitalization, in-hospital mortality, and reasons for poor compliance to ongoing treatment multivariate binary logistic regression was used to find independent predictors of in-hospital mortality which included variables with p <0.1 on univariate analysis. Structural break in the time series analysis was done by using Chow test. Results There was 53.8% reduction in number of neurological emergencies visiting ED during lockdown (22.1 visits vs. 10.2 visits per week, p = 0.001), significantly affecting rural population ( p = 0.004). Presenting patients had comparatively severe illness with increased requirement of MV ( p < 0.001) and significant delay in hospitalization during lockdown ( p < 0.001). Poor compliance to ongoing therapy increased from 34.4% in pre-lockdown to 64.7% patients during lockdown ( p < 0.001), mostly due to nonavailability of drugs ( p < 0.001). Overall, 35 deaths were recorded, with 20 (8.2%) in pre-lockdown and 15 (29.4%) during lockdown ( p = 0.001). Lockdown, nonavailability of local health care, delay in hospitalization, severity at admission, and need for MV emerged as independent predictors of poor outcome in stroke and delay in hospitalization in SE. Conclusion COVID-19 pandemic and associated lockdown resulted in marked decline in non-COVID neurological emergencies reporting to ED, with more severe presentations and significant delay from onset of symptoms to hospitalization.

Neurocritical Care of the Pregnant Patient.

PURPOSE OF REVIEW: To summarize recent changes in management and emerging therapies for pregnant neurocritical care patients. RECENT FINDINGS: Diagnostic and treatment options for managing neurologic emergencies in pregnant patients have expanded with both greater understanding of the effects of imaging modalities and medications on pregnancy and application of standard treatments for non-pregnant patients to pregnant populations. Specifically, this includes cerebrovascular diseases (pregnancy-associated ischemic stroke, pregnancy-associated intracerebral hemorrhage, cerebral venous sinus thrombosis), post-maternal cardiac arrest care, seizures and status epilepticus, myasthenia gravis, and fetal somatic support in maternal death by neurologic criteria. SUMMARY: With the exception of direct abdominal computed tomography (CT), most imaging studies are reasonably safe in pregnancy. When emergent imaging is needed to prevent maternal morbidity or mortality, any CT sequence with or without contrast is appropriate to pursue. Though new safety data on antiplatelets, antihypertensives, thrombolytics, and antiepileptic drugs have increased options for disease management in pregnancy, unfractionated and low-molecular weight heparin remain the safest options for anticoagulation. Early studies on hypothermia, ketamine, and immunomodulating therapies in pregnancy are promising. In myasthenia gravis, new data on adjunct devices may allow more patients to undergo safe vaginal delivery, avoiding cesarean section and the associated risk of crisis. When difficult decisions regarding preterm delivery arise, recent outcome studies can help inform discussion. Lastly, when the feared complication of maternal death by neurologic criteria occurs, fetal somatic support may help to save at least one life.

The diagnostic value of the neurological examination in coma of unknown etiology.

BACKGROUND: Identifying the cause of non-traumatic coma in the emergency department is challenging. The clinical neurological examination is the most readily available tool to detect focal neurological deficits as indicators for cerebral causes of coma. Previously proposed clinical pathways have granted the interpretation of clinical findings a pivotal role in the diagnostic work-up. We aimed to identify the actual diagnostic reliability of the neurological examination with regard to identifying acute brain damage. METHODS: Eight hundred and fifty-three patients with coma of unknown etiology (CUE) were examined neurologically in the emergency department following a predefined routine. Coma-explaining pathologies were identified retrospectively and grouped into primary brain pathology with proof of acute brain damage and other causes without proof of acute structural pathology. Sensitivity, specificity and percentage of correct predictions of different examination protocols were calculated using contingency tables and binary logistic regression models. RESULTS: The full neurological examination was 74% sensitive and 60% specific to detect acute structural brain damage underlying CUE. Sensitivity and specificity were higher in non-sedated patients (87/61%) compared to sedated patients (64%/59%). A shortened four-item examination protocol focusing on pupils, gaze and pyramidal tract signs was only slightly less sensitive (67%) and more specific (65%). CONCLUSIONS: Due to limited diagnostic reliability of the physical examination, the absence of focal neurological signs in acutely comatose patients should not defer from a complete work-up including brain imaging. In an emergency, a concise neurological examination should thus serve as one part of a multimodal diagnostic approach to CUE.

[Fast MRI sequences for clarification of acute neurological symptoms]. / Schnelle MRT-Sequenzen für die akute neurologische Abklärung.

CLINICAL/METHODICAL ISSUE: Neurological symptoms account for approximately 30% of emergency room (ER) visits. Clinical outcome often relies on a timely diagnosis and treatment initiation. Clinical imaging requirements are fast availability and high diagnostic value. STANDARD RADIOLOGICAL METHODS: Availability and quality of magnetic resonance imaging (MRI) in emergency rooms outside of core hours are limited compared to computed tomography (CT). Common reasons are infrastructural accessibility (hospitals using outpatient radiology centers), a lack of experienced and qualified staff and high patient compliance requirements. However, in a neurological emergency setting, MRI may show relevant advantages over CT in certain areas, such as diagnosis of stroke. METHODOLOGICAL INNOVATIONS: Advances in MRI technology have led to shorter exam times and robust motion reduction strategies. Common fast sequences and time reduction techniques for imaging of neurological emergencies are presented in this article. ACHIEVEMENTS: Recommendations for specific sequences or techniques depend on the institute's MRI hardware and software components. If available, parallel imaging is highly recommended for imaging of neurological emergencies. PRACTICAL RECOMMENDATIONS: Imaging of neurological emergencies requires fast, significant and motion insensitive standard acquisitions. Additional sequences should be acquired dependent on clinical and standard protocol imaging findings. An MRI emergency protocol is introduced for the most common neurologic emergencies including recommendations for fast MRI sequences and techniques for imaging time reduction.

Usefulness of electroencephalography for the management of epilepsy in emergency departments. / Utilidad del electroencefalograma en el manejo de la epilepsia en el Servicio de Urgencias.

INTRODUCTION: Electroencephalography (EEG) is an essential diagnostic tool in epilepsy. Its use in emergency departments (ED) is usually restricted to the diagnosis and management of non-convulsive status epilepticus (NCSE). However, EDs may also benefit from EEG in the context of other situations in epilepsy. METHODS: We conducted a retrospective observational study using the clinical histories of patients treated at our hospital's ED for epileptic seizures and suspicion of NCSE and undergoing EEG studies in 2015 and 2016. We collected a series of demographic and clinical variables. RESULTS: Our sample included 87 patients (mean age of 44 years). Epileptic seizures constituted the most common reason for consultation: 59.8% due to the first episode of epileptic seizures (FES), 27.6% due to recurrence, and 12.6% due to suspected NCSE. Interictal epileptiform discharges (IED) were observed in 38.4% of patients reporting FES and in 33.3% of those with a known diagnosis of epilepsy. NCSE was confirmed by EEG in 36.4% of all cases of suspected NCSE. Presence of IED led to administration of or changes in long-term treatment in 59.8% of the patients. CONCLUSIONS: EEG is a useful tool for seizure management in EDs, not only for severe, sudden-onset clinical situations such as NCSE but also for diagnosis in cases of non-affiliated epilepsy and in patients experiencing the first episode of epilepsy.

The Role of Decompressive Craniectomy in Limited Resource Environments.

Decompressive craniectomy (DC) is a neurosurgical procedure useful to prevent and manage the impact of high intracranial pressure (ICP) that leads to brain herniation and brain's tissue ischemia. In well-resourced environment this procedure has been proposed as a last tier therapy when ICP is not controlled by medical therapies in the management of different neurosurgical emergencies like traumatic brain injury (TBI), stroke, infectious diseases, hydrocephalus, tumors, etc. The purpose of this narrative review is to discuss the role of DC in areas of low neurosurgical and neurocritical care resources. We performed a literature review with a specific search strategy in web repositories and some local and regional journals from Low and Middle-Income Countries (LMICs). The most common publications include case reports, case series and observational studies describing the benefits of the procedure on different pathologies but with several types of biases due to the absence of robust studies or clinical registries analysis in these kinds of environments.

Neuro-Ophthalmology at the Bedside: A Clinical Guide.

Neuro-ophthalmological signs and symptoms are common in the emergency department but are a frequent source of diagnostic uncertainties. However, neuro-ophthalmological signs often allow a precise neuro-topographical localization of the clinical problem. A practical concept is presented how to perform a neuro-ophthalmological examination at the bedside and to interpret key findings under the aspect of emergency medicine with limited resources.

Emergency electroencephalogram: Usefulness in the diagnosis of nonconvulsive status epilepticus by the on-call neurologist. / Uso de la electroencefalografía urgente por el neurólogo de guardia: utilidad en el diagnóstico del estatus epiléptico no convulsivo.

INTRODUCTION: We aim to describe the use of emergency electroencephalogram (EmEEG) by the on-call neurologist when nonconvulsive status epilepticus (NCSE) is suspected, and in other indications, in a tertiary hospital. SUBJECTS AND METHODS: Observational retrospective cohort study of emergency EEG (EmEEG) recordings with 8-channel systems performed and analysed by the on-call neurologist in the emergency department and in-hospital wards between July 2013 and May 2015. Variables recorded were sex, age, symptoms, first diagnosis, previous seizure and cause, previous stroke, cancer, brain computed tomography, diagnosis after EEG, treatment, patient progress, routine control EEG (rEEG), and final diagnosis. We analysed frequency data, sensitivity, and specificity in the diagnosis of NCSE. RESULTS: The study included 135 EEG recordings performed in 129 patients; 51.4% were men and their median age was 69 years. In 112 cases (83%), doctors ruled out suspected NCSE because of altered level of consciousness in 42 (37.5%), behavioural abnormalities in 38 (33.9%), and aphasia in 32 (28.5%). The EmEEG diagnosis was NCSE in 37 patients (33%), and this was confirmed in 35 (94.6%) as the final diagnosis. In 3 other cases, NCSE was the diagnosis on discharge as confirmed by rEEG although the EmEEG missed this condition at first. EmEEG performed to rule out NCSE showed 92.1% sensitivity, 97.2% specificity, a positive predictive value of 94.6%, and a negative predictive value of 96%. CONCLUSIONS: Our experience finds that, in an appropriate clinical context, EmEEG performed by the on-call neurologist is a sensitive and specific tool for diagnosing NCSE.

Emergencias neuropediatricas en niños atendidos en el Hospital Universitario de Maracaibo / Neuropaediatric emergencies in children admitted to the Hospital Universitario, Maracaibo, Venezuela

Durante los últimos años se ha observado un incremento en el número de consultas en los servicios de emergencias pediátricas de forma proporcional al incremento de las consultas por motivos neurológicos. Objetivos: Analizar la demanda de la actividad asistencial neuropediátrica y conocer los motivos de consultas más frecuentes y su distribución epidemiológica. Métodos: Estudio observacional de cohorte histórica mediante el registro prospectivo durante un año en el servicio de Emergencia Pediátrica del Hospital Universitario de Maracaibo. Resultados: Se solicitó evaluación neuropediátrica a 172 pacientes constituyendo el 0,17 % de todas las emergencias entre 0 y 15 años de edad, predominando los lactantes (39%) y niños varones (53,5%). Las crisis convulsivas son el motivo de consulta más frecuente (45%), seguidas del retraso psicomotor y la sospecha de encefalopatías estáticas. La epilepsia fue el principal diagnóstico de ingreso (23%) y egreso (25%) seguido de meningitis bacteriana aguda. Conclusiones: Las urgencias neurológicas constituyen un porcentaje significativo del total de las urgencias pediátricas. Son muchos los motivos de consulta y es rol del pediatra de emergencias solicitar la valoración especializada. Las crisis convulsivas, retraso psicomotor, infecciones del sistema nervioso central, síncope y cefalea constituyen los cinco principales motivos de consulta. Sin embargo la demora psicomotora no constituye una urgencia, por lo que el pediatra debe estar en capacidad de tomar la decisión acertada a quien debe derivar y solicitar la consulta por el especialista de forma inmediata.

In recent years there has been an increase in the number of consultations in pediatric emergency services in proportion to the increase in consultations for neurological reasons.Objectives: To analyze the demand of neuropaediatric care, and to determine the most frequent reasons for neuropediatric consultations. Methods: Historical cohort observational study by means of a prospective registry during one year in the Pediatric Emergency Service of the University Hospital of Maracaibo, Venezuela. Results: Neuropediatric evaluation was requested for 172 patients, 0.17% of all emergencies, ages from 0 to 15 years, predominantly infants (39%) and boys (53.5%). Seizures were the most frequent reason for consultation (45%), followed by psychomotor retardation and suspected static encephalopathies. Epilepsy was the most frequent diagnosis at admission (23%) and discharge (25%), followed by acute bacterial meningitis. Conclusions: Neurological emergencies constitute a significant percentage of all pediatric emergencies. There are many reasons for consultation and the pediatrician's role is to decide who deserves specialized neurologic care or who may be derived for an outpatient emergency assessment. Seizures, psychomotor retardation, central nervous system infections, syncope and headache, were the five main reasons for consultation; however psychomotor delay does not constitute an emergency, so the pediatrician should be able to decide which patient should be derived to the neuropediatrician.

Análisis de las consultas neurológicas en el Servicio de Urgencia de un hospital terciario / Analysis of the neurologic consultations in the Emergency Deparment at a tertiary hospital

Introducción: Las urgencias neurológicas constituyen el 10-15% de las urgencias médicas. Los principales motivos de consulta son la enfermedad cerebrovascular, crisis epilépticas y cefalea. El Hospital Dr. Hernán Henríquez A. (HHHA) comenzó con neurólogos en el Servicio de Urgencia Adultos (SUA) en horario hábil, en abril de 2011. En julio de 2013 se iniciaron turnos con neurólogo 24/7, presenciales en el SUA. Objetivo: Describir el perfil clínico de las consultas neurológicas en el SUA de nuestro centro. Método: Muestra noprobabilística, por conveniencia, de las consultas realizadas en el Turno N°1, del SUA-HHHA, entre octubre de 2013 y septiembre de 2014. El análisis estadístico se realizó con el software STATA 12.0. Resultados: Se registraron 1.080 consultas en el período. 51,2% fueron mujeres. Promedio de edad = 58 años (DE = 20,2). El 36,7% de las consultas se realizó en horario inhábil. Los diagnósticos más frecuentes fueron infarto cerebral (30,7%), epilepsia (15%) y cefalea (11,3%). El 34,6% de los pacientes fue dado de alta; 25,8% se hospitalizó en el Servicio de Medicina Interna; 21% fue derivado a otros hospitales; 12% fue derivado a otros especialistas y 5,7% ingresó a la Unidad de Paciente Crítico. 0,83% de los pacientes falleció en el SUA. Conclusiones: Los principales motivos de consulta neurológica en nuestro Servicio de Urgencia fueron enfermedades cerebrovasculares, epilepsia y cefalea. Debido a que más de un tercio de las consultas ocurre en horario inhábil, se justifica el sistema de neurología 24/7 presencial en el Servicio de Urgencia.

Introduction: Neurological emergencies constitute 10-15% of medical emergencies. The main reasons for consultation are cerebrovascular disease, seizures and headaches. Dr. Hernan Henriquez Hospital (HHHA) began with neurologists in the Adult Emergency Service in April 2011. In July 2013 24/7 neurology shifts at emergency room were added. Objective: To describe the clinical profile of neurologic consultations at our emergency center. Method: A convenience sample of consultations on shift No. 1, at the Adult Emergency Service HHHA between October 2013 and September 2014. The statistical analysis was performed using STATA 12.0 software. Results: 1,080 consultations were recorded in theperiod. 51.2% were women. Mean age = 58 years (SD = 20.2). 36.7% of consultations are conducted in a non-business hour. The most frequent diagnoses were stroke (30.7%), epilepsy (15%) and headache (11.3%). 34.6% ofpatients were discharged; 25.8% were hospitalized in the Internal Medicine dept; 21% were referred to other hospitals; 12% were referred to other specialists and 5.7% were admitted to Critical Patient Unit. 0.83% of the patients died in the SUA. Conclusions: The main reasons for neurological consultation at our Emergency Service were cerebrovascular disease, epilepsy and headaches. Because more than a third of consultations occur on non-schedule hours, neurology system 24/7 shifts are justified in the Emergency Service.
