Changes in pediatric referrals after the 2009 ketogenic diet consensus recommendations.

BACKGROUND: In 2009, the International Ketogenic Diet Study Group published recommendations for children receiving ketogenic diet (KD) therapy for epilepsy. The document included a table listing epilepsy syndromes and conditions in which the KD has been particularly beneficial, hoping that physicians would refer children for the KD sooner. PURPOSE: To measure the impact of these 2009 recommendations on referral practice, we compared children initiated on the KD at Johns Hopkins Hospital (JHH) 10 years before and after the recommendations. RESULTS: Overall, children referred to the KD who met indications increased from the pre- to post-recommendation group, 44 % (112/256) to 69 % (175/255) (p < 0.001), with JHH neurologists specifically referring more frequently (10/112, 9 % to 58/175, 33 %) (p < 0.01). Referrals increased for Glut-1 deficiency (0 % to 2.4 %, p = 0.015), Dravet syndrome (0 % to 6.7 %, p < 0.01), Rett syndrome (0.4 % to 3 %, p = 0.018), and formula-fed only status (16 % to 31 %, p < 0.01). The chances of > 50 % seizure reduction for all children referred improved slightly between decades (56 % to 61 %, p = 0.30). CONCLUSIONS: Following the 2009 recommendations, our study shows there was an increase in referrals for children with indications at our center. Referrals from neurologists at our own institution increased the most. Ketogenic diet efficacy improved slightly over time but did not reach significance.

A Comparison of Patients' and Neurologists' Assessments of their Teleneurology Encounter: A Cross-Sectional Analysis.

Background and Objectives: To better understand patients' and neurologists' assessments of their experiences regarding effectiveness of teleneurology encounters. Methods: Following an audio-video telehealth visit, neurologists asked patients to participate in a survey-based research study about the encounter, and then, the neurologists also recorded their own evaluations. Data were analyzed using standard quantitative and qualitative techniques for dichotomous and ordered-category survey responses in this cross-sectional analysis. Results: The study included unique encounters between 187 patients and 11 general neurologists. The mean patient age was 49 ± 17.5 years. Two thirds of the patients (66.8%, 125/187) were female. One third (33.2%; 62) were patients new to the NYU Langone Health neurology practices. The most common patient chief complaints were headache (69/187, 36.9%), focal and generalized numbness or tingling (21, 11.2%), memory difficulty (15, 8%), spine-related symptoms (12, 6.4%), and vertigo (11, 5.9%). Most patients (94.7%, 177/187) reported that the teleneurology encounter satisfied their needs. Patients and their neurologists agreed that the experience was effective in 91% (162/178) of encounters, regardless of whether the visit was for a new or established patient visit. Discussion: More than 90% of new and established patients and their neurologists agreed that teleneurology encounters were effective despite some limitations of the examination, the occasional need for patient assistance, and technical difficulties. Our results provide further evidence to justify and to expand the clinical use of teleneurology.

Neurologists' Evaluations of Experience and Effectiveness of Teleneurology Encounters.

Background and Objectives: To better understand neurologists' assessments of the experiences and effectiveness of teleneurology encounters. Methods: After completing an audio-video telehealth visit with verbally consenting patients, neurologists recorded their evaluations of the encounter. Data were analyzed using standard quantitative and qualitative techniques. Results: The study included unique encounters between 187 patients and 11 neurologists. The mean patient age was 49 ± 17.5 years. Two thirds of patients (66.8%, 125/187) were female. One third of patients (33.2%; 62) were new patients. The most common patient complaints were headache (69/187, 36.9%), focal and generalized numbness or tingling (21, 11.2%), memory difficulty (15, 8%), spine-related symptoms (12, 6.4%), and vertigo (11, 5.9%). Neurologists reported that they completed a virtual examination that provided enough information for medical decision-making in 94.9% of encounters (169/178, 9 missing responses). Fourteen of 25 examination elements important for medical decision-making could be performed sufficiently during virtual encounters. Examination assistance was needed for 16.4% (30/183) of patients, who were, on average, 17.3 years older than those who did not require assistance (62.9 years vs. 45.6 years, p = 0.0002). In 19.1% (34/178) of encounters, neurologists learned clinically relevant information from seeing patients in their homes. Neurologists' assessments of the effectiveness of encounters were not related to the presence (97.2%, 35/36 effective) or absence (95%, 134/141 effective) of technical difficulties (p = 0.5729) in 177 encounters (10 missing responses). Discussion: Neurologists reported that nearly 95% of teleneurology encounters were effective despite limitations of the virtual examination, occasional need for patient assistance, and technical difficulties.

Curriculum Innovations: A Comprehensive Teleneurology Curriculum for Neurology Trainees.

Introduction and Problem Statement: As the role of teleneurology expands, it is important to prepare trainees to perform virtual encounters proficiently. Objectives: We created a comprehensive multimodality teleneurology curriculum for residents to teach key aspects of telehealth encounters including the virtual examination and skill development across several environments. Methods and Curriculum Description: We developed and implemented a teleneurology curriculum focused on teaching the virtual neurologic examination, measuring teleneurology competency, and providing opportunities for trainees to perform telehealth encounters in multiple settings. Residents (N = 22) were first surveyed on what methods would be most helpful to learn teleneurology. Trainees observed a faculty member conducting a teleneurology visit with another faculty member playing a patient. Residents then practiced a teleneurology encounter during a 10-minute objective structured clinical examination (OSCE) at a simulation center. After positive feedback from the fall of 2020, we adapted the OSCE to be completely remote in the spring of 2021 for senior residents. Trainees then performed teleneurology visits during their continuity clinics and subspecialty clinic rotations. Results and Assessment Data: All neurology residents from adult and child neurology and neuropsychiatry programs at New York University Grossman School of Medicine participated in the curriculum. Residents identified a variety of teaching modalities that would help them learn teleneurology: didactics with slides (25%), live demonstration (25%), simulated experience (23%), starting with live patients (23%), and articles/reading material (4%). To date, 68 trainees participated in the OSCE. Trainees who completed on-site and remote simulations reported increased comfort (p < 0.05) and interest in teleneurology (p < 0.05) and requested more access to simulations during training. Sensorimotor assessment and adequate visualization of the affected limb were identified as areas for improvement. Discussion and Lessons Learned: Our multimodal 3-year teleneurology curriculum provides opportunities for residents to learn and apply teleneurology. Survey tools helped strengthen the curriculum to optimize educational potential. We implemented a teleneurology simulation with and without the use of a simulation center. We plan to expand our teleneurology clinical and simulation experiences to trainees based on our data and further developments in teleneurology and to track the progress of teleneurology skills as residents advance through training.

Seizure mimics in children: An age-based approach.

BACKGROUND: In order to distinguish seizure mimics from seizures in children it is important to clarify the event duration, frequency, semiology, and any precipitating factors. METHODOLOGY: This review provides a succinct and up-to-date overview aimed at general and subspecialty non-neurologist pediatric and adolescent health care providers to help guide a diagnostic approach when a child presents with paroxysmal events of unclear etiology. RESULTS: In many cases, seizure mimics are consistently triggered by an event, location, or emotion, and often resolve with distraction or tactile stimulation. Suspicion should be raised for seizures when events occur out of deep sleep, there is a loss of consciousness with the event, movements are not suppressible, and there is a period of fatigue afterword (minutes to hours). Further, a past medical history of developmental delay (e.g. autism), developmental regression, or neurologic injury increases patients' risk for seizures. CONCLUSIONS: Common seizure mimics are highlighted in the age group in which they are most prevalent.

Decreased relative efficacy of the ketogenic diet for children with surgically approachable epilepsy.

PURPOSE: In children with intractable, surgically approachable epilepsy, the ketogenic diet is often perceived as less efficacious than surgery. METHODS: A retrospective chart review was performed of 554 children started on the ketogenic diet since 1994. Forty-five children were identified as surgical candidates, with at least 2 focal routine EEGs, ictal video-EEG, and corresponding focal neuroimaging findings, of whom 24 eventually had resective surgery and were followed subsequently. A comparison cohort group was also created of 45 children matched for age and seizure frequency that received the diet but were not surgical candidates (multifocal or generalized seizures). RESULTS: Of the 24 children who received both dietary and surgical therapies, there was a higher likelihood after 6 months of both >90% seizure reduction (71% versus 17%) and seizure freedom (63% versus 0%) following surgery, both p < 0.0001. Similarly, the 45 cohort children who were not surgical candidates were more likely to be seizure-free (29% versus 13%, p = 0.041) and remained on the diet for shorter duration (10 months versus 18 months, p = 0.035) compared to the surgical group. CONCLUSION: Children with surgically approachable epilepsy do respond to the diet, but are more likely to be seizure-free following surgery.
