[Guide for the treatment of acute altered mental status. Iberoamerican Academy of Pediatric Neurology]. / Guía de tratamiento de la alteración aguda del estado mental. Academia Iberoamericana de Neurología Pediátrica.

In pediatric patients, an acute altered mental status refers to a sudden and significant change in a child's brain function and level of consciousness. It may manifest as confusion, disorientation, agitation, lethargy or even a loss of consciousness. This condition is a medical emergency, and requires immediate evaluation and attention. There are several causes of acute altered mental status in children, including infections of the central nervous system such as meningitis or encephalitis, traumatic brain injury, metabolic disorders, seizures and poisoning, among others. The aim of this study was to analyse, prepare and classify the current literature in order to determine the best recommendations for the treatment of cases of acute altered mental status with various causes in pediatric patients. The study was based on opinions from experts in the field in order to classify the recommendations, and was submitted to the scientific committee of the Iberoamerican Academy of Pediatric Neurology for review. Our guide is an aid for the treatment of this non-specific symptom based on a basic and advanced approach, which can be applied by any pediatric neurologist.

Narcolepsy: an interface among neurology, immunology, sleep, and genetics.

Narcolepsy is a primary disorder of the central nervous system resulting from genetic, environmental, and immunological interactions defined as excessive daytime sleepiness plus cataplexy, hallucinations, sleep paralysis, and sleep fragmentation. The pathophysiology is not entirely known, but the interaction among genetic predisposition, environmental exposition, and immune component with consequent hypocretin-1 deficiency is the model to explain narcolepsy type I. The mechanism of narcolepsy type II is less understood. There is a delay of over ten years for the diagnosis of narcolepsy around the world. Patients with narcolepsy have many comorbidities with a negative impact on quality of life. The treatment of narcolepsy must contain an educational approach for the family, coworkers, and patients. Scheduled naps and sleep hygiene are essential to minimize the dose of medications. Much progress has been seen in the pharmacological treatment of narcolepsy with new stimulants, different presentations of oxybate, and recent studies with orexin agonists. Narcolepsy is a rare disease that needs to be more understood and highlighted to avoid delayed diagnosis and severe disabilities in patients.

A narcolepsia é um distúrbio primário do sistema nervoso central resultante das interações genéticas, ambientais e imunológicas definidas como sonolência diurna excessiva mais cataplexia, alucinações, paralisia do sono e fragmentação do sono. A fisiopatologia não é completamente conhecida, mas a interação entre predisposição genética, exposição ambiental e componente imunológico com consequente deficiência de hipocretina-1 é o modelo para explicar a narcolepsia tipo I. O mecanismo da narcolepsia tipo II é menos compreendido. Há um atraso de mais de dez anos para o diagnóstico da narcolepsia em todo o mundo. Pacientes com narcolepsia apresentam muitas comorbidades com impacto negativo na qualidade de vida. O tratamento da narcolepsia deve conter uma abordagem educativa para a família, colegas de trabalho e pacientes. Cochilos programados e higiene do sono são importantes para minimizar a dose dos medicamentos. Muito progresso foi observado no tratamento farmacológico da narcolepsia com novos estimulantes, diferentes apresentações de oxibato e estudos recentes com agonistas de orexina. A narcolepsia é uma doença rara que precisa ser mais compreendida e destacada para evitar atrasos no diagnóstico e incapacidades graves nos pacientes.

Barriers to increasing paid parental leave in U.S. neurology residencies: a survey of program directors.

BACKGROUND: The American Board of Psychiatry and Neurology (ABPN) and the Accreditation Council for Graduate Medical Education (ACGME) require that residency programs allow at least 6 weeks of parental leave. The American Medical Association (AMA) recommends 12 weeks of paid parental leave. Despite these recommendations, there is little information about parental leave policies across U.S. neurology residencies. The objective of our study was to assess parental leave policies in U.S. adult neurology residencies and barriers to increasing the duration of leave. METHODS: We distributed an anonymous online survey to U.S. adult neurology program directors (PDs) to assess demographics, components and length of parental leave, perceived impact on residents' clinical training and academic development, and barriers to increasing the length of leave. RESULTS: We contacted 163 PDs and received 54 responses (response rate of 33%). 87% reported policies for both childbearing and non-childbearing residents. The average maximal length of leave allowed without extension of training was 8.5 weeks (range 0-13) for childbearing and 6.2 weeks (range 0-13) for non-childbearing residents. Most PDs felt that parental leave had a positive impact on resident wellness and neutral impact on clinical competency, academic opportunities, and career development. The most common barriers to providing a 12-week paid policy were concerns about equity in the program (82%), staffing of clinical services (80%), and impact on clinical training (78%). CONCLUSIONS: Although most programs in our study have parental leave policies, there is significant variability. Policies to improve parental leave should focus on addressing common barriers, such as additional solutions to staffing clinical services.

Neurology Training and Medical Education in Resource-Limited Settings: Building and Growing the First Neurology Residency Program in East Africa.

The burden of neurological disease disproportionately affects low- and middle-income countries, where the lowest number of neurologists are located. Building local training opportunities in resource-limited settings is a foundational step to enhancing the neurological workforce and improving access to neurological care in these regions. In this article, we describe the development and growth of the first neurology residency program in East Africa, which was established in 2006 at Zewditu Memorial Hospital and the Tikur Anbessa Specialized Hospital, Addis Ababa University, Ethiopia. We highlight the impact of the program on clinical care, research, collaborations between neurologists across Ethiopia, and ways to build educational opportunities and mentorship while faced with limited resources. The main challenges in starting the residency program included lack of faculty with neurological expertise, lack of a precedent for subspecialty training in our setting, as well as limited resources and space. The formation of sustainable international collaborations with clinicians at established institutions in high-income countries and neurological societies has been a major source of support in developing the initial infrastructure, curriculum and educational content, knowledge assessments, and mentored research projects. Local partnerships with related medical specialties, including internal medicine, critical care, neurological surgery, and psychiatry, were also instrumental in creating training opportunities. As the program continues to evolve, many challenges remain, including limited diagnostics, lack of access to advanced treatment modalities, lack of fellowship training opportunities in various neurological subspecialties, and insufficient training and experience in scientific writing. Despite these challenges, the residency program has persevered and its creation resulted in many positive changes: since its inception in 2006, we graduated 80 neurologists and the number of practicing neurologists in Ethiopia has increased from 5 to 78, our institution has evolved into a national referral center for neurology, graduates have published 61 articles in the past 3 years and contributed to international neurology research, and alumni of the program have grown the Association of Ethiopian Neurologists. Future directions include development of fellowship opportunities, creation of international rotations, and implementation of teleneurology to further strengthen neurological care across Ethiopia.

Painful Eyes in Neurology Clinic: A Guide for Neurologists.

Eye pain is a common complaint among patients presenting to the neurology clinic. It can be related to neurologic diseases, but it can also be a localized eye condition. Such disorders can be misleading, as their benign appearance might mask more grave underlying conditions, potentially leading to misdiagnoses or delayed treatment. Clinicians should be aware of the specific neurologic or systemic disorders (eg, demyelinating diseases or vascular abnormalities) that might first manifest as eye pain. Formal ophthalmic consultation is recommended for patients presenting with eye pain as the predominant complaint especially when red flags for more serious pathology are present.

[Neuropsychiatric associations in Belgium: from foundation to separation (1869-2008)]. / Neuropsychiatrische verenigingen in België: van ontstaan tot splitsing (1869-2008).

Background Professional associations have traditionally been important to the specialization process and identity of medical specialists. Psychiatry and neurology share common origins in the 19th century and subsequently went through a major evolution. However, relatively little is known about the role of neuropsychiatric associations. Aim To provide a concise historical overview of the Belgian neuropsychiatric associations and understand the factors that mattered in their formation and dissolution. Method Descriptive research based on oral testimonies, archival material, journals of the concerned associations and secondary literature. Results In 1869, the then ‘alienists’ founded the first Belgian psychiatric association. Subsequently, three fault lines – professional associations versus scientific associations, regional versus national associations, neurological versus psychiatric associations – led to the current neurological and psychiatric associations in Belgium. Conclusion Over time, the neuropsychiatric associations have helped define the identity of neurology and psychiatry. On the other hand, the associations themselves have been subject to both substantive factors, i.e. the evolution of the discipline, and non-substantive factors. The latter are specific to Belgium and concern linguistic struggles and a historically created split between scientific associations and professional associations.

Diversity, equity, and inclusion (DEI) in medical education: DEI at the bedside.

BACKGROUND: The ability to recognize and address bias is an important communication skill not typically addressed during training. We describe the design of an educational curriculum that aims to identify and change behavior related to diversity, equity, and inclusion (DEI). "DEI at the Bedside" uses the existing infrastructure of bedside teaching and provides a tool to normalize DEI discussions and develop skills to address bias during a neurology inpatient rotation. METHODS: As part of traditional clinical rounds, team members on an inpatient service shared experiences with DEI topics, including bias. The team developed potential responses should they encounter a similar situation in the future. We report the results of our needs assessment and curriculum development to evaluate the feasibility of incorporating a DEI educational curriculum in the neurology inpatient setting. RESULTS: Forty-two DEI experiences were recorded. Medical students were the most frequent discussants (44%). Direction of bias occurred between healthcare team members (33%), against patients (31%), and patients against healthcare team members (28%). Experiences ranged from microaggressions to explicit comments of racism, sexism, and homophobia. CONCLUSIONS: Based on needs assessment data, we developed a DEI educational curriculum for the inpatient neurology setting aimed to improve knowledge and skills related to DEI topics as well as to normalize conversation of DEI in the clinical setting. Additional study will demonstrate whether this initiative translates into measurable and sustained improvement in knowledge of how bias and disparity show up in the clinical setting and behavioral intent to discuss and address them.

Needs assessment for direct ophthalmoscopy training in neurology residency.

BACKGROUND: Assessment of the ocular fundus, traditionally by direct ophthalmoscopy (DO), is essential to evaluate many neurologic diseases. However, the status of DO training in neurology residencies is unknown. We conducted a needs assessment to determine current attitudes, curricula, and gaps in DO training. METHODS: A survey was developed and administered to residents and program directors (PDs) at ACGME accredited neurology residencies in the United States. The survey assessed factors such as current DO curricula, perceived importance of DO, confidence of skills, and need for improvement. Data analysis was performed using the Mann Whitney U test and Fisher Exact Test. RESULTS: Nineteen PDs (11.6%) and 74 (41.1%) residents responded to the survey. 97.1% of residents and 100.0% of PDs believe DO is an important skill to learn. 29.4% of PDs expected graduating residents to have completed > 10 supervised DO exams, while 0.0% of graduating fourth year residents reported doing so (p = 0.03). 35.7% of graduating residents had never correctly identified an abnormal finding on DO. The number of times residents practiced DO unsupervised correlated with increasing confidence in all components of the DO exam (p < 0.05). Residents who felt their program emphasized DO were more likely to perform DO at least once a week compared to residents who did not perceive program emphasis (61.9% vs. 35.0%, p = 0.02) and were more confident in DO (p < 0.05). 66.7% of residents and 42.1% of PDs were not satisfied with current levels of DO training. 96.7% of residents and 78.9% of PDs felt it was important to improve curriculum for DO training. Supervised practice and practice skills sessions were identified as the most helpful interventions to improve DO training. CONCLUSIONS: The vast majority of neurology PDs and residents believe DO is an important skill to learn, are unsatisfied with the current level of DO training, and advocate for improvement in DO curricula. Current DO curricula have limited formal didactic training and supervised practice. The bulk of DO learning occurs through unsupervised practice, which is influenced by motivational factors such as perceived residency emphasis on DO learning.

Update on Neuro-ophthalmic Manifestations of Immune Checkpoint Inhibitors.

PURPOSE OF REVIEW: Immune checkpoint inhibitor (ICI) use has been on the rise for treatment of many different malignancies. Subsequently, more has been learned about immune-related adverse events (irAEs) that occur up to 12 months after treatment. This review summarizes the latest findings and management of neuro-ophthalmic associated irAEs. RECENT FINDINGS: irAEs can affect the afferent and efferent neuro-ophthalmic pathways, thereby targeting central and peripheral nervous systems. As more cases are being reported, it is becoming apparent that neuro-ophthalmic irAEs often present with atypical features when compared to their spontaneous autoimmune counterparts. These neuro-ophthalmic presentations can also be signs of a more extensive inflammatory process that spans other organ systems, such as myopathies, endocrinopathies, and paraneoplastic syndromes. Awareness of neuro-ophthalmic irAEs and their atypical presentations can lead to early detection, termination of ICI treatment, and immunosuppressant therapy initiation.

Evolving concepts in margin strategies and adaptive radiotherapy for glioblastoma: A new future is on the horizon.

Chemoradiotherapy is the standard treatment after maximal safe resection for glioblastoma (GBM). Despite advances in molecular profiling, surgical techniques, and neuro-imaging, there have been no major breakthroughs in radiotherapy (RT) volumes in decades. Although the majority of recurrences occur within the original gross tumor volume (GTV), treatment of a clinical target volume (CTV) ranging from 1.5 to 3.0 cm beyond the GTV remains the standard of care. Over the past 15 years, the incorporation of standard and functional MRI sequences into the treatment workflow has become a routine practice with increasing adoption of MR simulators, and new integrated MR-Linac technologies allowing for daily pre-, intra- and post-treatment MR imaging. There is now unprecedented ability to understand the tumor dynamics and biology of GBM during RT, and safe CTV margin reduction is being investigated with the goal of improving the therapeutic ratio. The purpose of this review is to discuss margin strategies and the potential for adaptive RT for GBM, with a focus on the challenges and opportunities associated with both online and offline adaptive workflows. Lastly, opportunities to biologically guide adaptive RT using non-invasive imaging biomarkers and the potential to define appropriate volumes for dose modification will be discussed.

Changing landscape in the field of paraneoplastic neurology: Personal perspectives over a 35-year career.

Paraneoplastic neurologic syndromes are a group of rare disorders that have fascinated neurologists for more than a century. The discovery in the 1980s that many of these disorders occurred in association with antibodies against neuronal proteins revived the interest for these diseases. This chapter first traces the history of the paraneoplastic neurologic syndromes during the era that preceded the discovery of immune mechanisms and then reviews the immunologic period during which many of these syndromes were found to be associated with antibodies against intracellular onconeuronal proteins and pathogenic cytotoxic T-cell mechanisms. Alongside these developments, investigations on the antibody-mediated disorders of the peripheral nervous system, such as the myasthenic syndromes or neuromyotonia, provided suggestions for the study of the central nervous system (CNS) syndromes. These converging areas of research culminated with the groundbreaking discovery of a new category of CNS disorders mediated by antibodies against neuronal surface proteins or receptors. These disorders are not always paraneoplastic, and the understanding of these syndromes and mechanisms has changed the landscape of neurology and neurosciences.
