Purpose of review: To provide an update on advancements in pediatric headache.

Recent findings: The symptomatology associated with primary headache disorders has been compared with ICHD-3 criteria. Primary stabbing headache pain lasts longer than 3 seconds in over half of patients. Persistent posttraumatic headache or new daily persistent headache have significant overlap in pain character and nonpain-related symptoms with migraine. In a large cohort with continuous headache at first follow-up, 47% reported resolution of their continuous headache and 19.4% had a 50% or greater reduction in frequency with improvements in fluid intake, sleep, not skipping meals, and exercise. There was no correlation with improved lifestyle habits and clinical outcomes despite the overall improvement. Studies noted significant improvement in headache scores with onabotulinum toxin A and incobotulinum toxin A injections with limited side effects. Intranasal sumatriptan without concurrent intravenous therapies found a clinically meaningful decrease in pain score prior to discharge with shorter lengths of stay and lower emergency department costs compared with the those who received intravenous therapies.

Summary: Newer studies have suggested changes to symptomatology and duration of pediatric headache syndromes. Onabotulinum toxin A and incobotulinum toxin A injections, and emergency department intranasal sumatriptan are well tolerated therapies in pediatric headache.

Purpose of review: This review aims to provide an overview of the current understanding of eosinophilic gastrointestinal disorders (EGIDs) and the role of the epithelium in influencing disease pathogenesis to inform and devise future therapeutic strategies.

Recent findings: Changes in epithelial cell structure, functions, and integrity are observed in EGIDs. In eosinophilic esophagitis (EoE), the esophageal epithelium has been shown to play key roles in perpetuating the inflammatory response in EoE through the expression of pro-inflammatory cytokines and immunological cell-surface proteins. Similar mechanisms appear to exist in the other EGIDs, including eosinophilic gastritis (EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). Because of the increasing rarity of each non-EoE EGID, research focusing on how the epithelium is modulating disease in each lower gastrointestinal compartment is still in its rudimentary stages.

Summary: While there has been significant progress in understanding the role of the epithelium in EoE, further research is needed to obtain a better understanding of the mechanisms mediating epithelial-immune crosstalk in non-EoE EGIDs. Using EoE-epithelial cell research to inform future EGID investigations could lead to the development of new therapeutic interventions, such as targeted therapies to restore epithelial barrier function and reduce inflammation, to improve rare disease-patient quality of life.

Purpose of review: Critically ill children are at risk of neurologic dysfunction and acquiring primary and secondary brain injury. Close monitoring of cerebral function is crucial to prevent, detect, and treat these complications.

Recent findings: A variety of neuromonitoring modalities are currently used in pediatric and neonatal ICUs. These include noninvasive modalities, such as electroencephalography, transcranial Doppler, and near-infrared spectroscopy, as well as invasive methods including intracranial pressure monitoring, brain tissue oxygen measurement, and cerebral microdialysis. Each modality offers unique insights into neurologic function, cerebral circulation, or metabolism to support individualized neurologic care based on a patient's own physiology. Utilization of these modalities in ICUs results in reduced neurologic injury and mortality and improved neurodevelopmental outcomes.

Summary: Monitoring of neurologic function can significantly improve care of critically ill children. Additional research is needed to establish normative values in pediatric patients and to standardize the use of these modalities.

Purpose of review: Provide an overview of recent findings and recommendations for the presentation, diagnosis, and management of pediatric dermatologic emergencies.

Recent findings: Updated information on optimal diagnosis and treatments for pediatric dermatologic emergencies because of infection, reactive infectious mucocutaneous eruption, and serious cutaneous adverse reactions are covered.

Summary: Pediatric dermatologic emergencies require prompt diagnosis and management. This review covers new agents and techniques for management and diagnosis.

Purpose of review: To provide a comprehensive resource for pediatric surgeons and pediatricians caring for patients with Mullerian and vaginal anomalies, with a focus on recent changes in practice.

Recent findings: Herein, we provide a foundation for understanding the anatomy, presentation, and work up of Mullerian and vaginal anomalies. We review how to approach management of these anomalies when in isolation or when associated with anorectal malformations. We discuss the evolution of the management of neovaginal discussion with a current emphasis on patient-centered and directed care.

Summary: Review of current understanding of and approach to Mullerian and vaginal anomalies in children.

Purpose of review: A growing number of gene therapies are getting FDA-approved for pediatric rare disorders to treat once incurable diseases. Opportunities for preventing lifetime illness and improving quality of life for these patients is now becoming a reality. Challenges exist in navigating the complexities of determining which patients will benefit from these new gene therapies and how to effectively deliver them as a standard of care.

Recent findings: Gene therapies have been approved for pediatric hematological, neuromuscular, cancer, and other disorders that have improved the quality of life for rare disease patients. FDA approval of these drugs has been on a case-by-case basis leading towards gaps in drug approval, physician and patient knowledge of new gene therapies, and ultimate delivery of these drugs. Identifying patients that would benefit from these drugs and other coordination of care issues have arisen with each unique gene therapy product. These gene therapies have unique requirements and patient indications that require a knowledgeable group of physicians and hospital administrators to incorporate their use as a standard of care. With more gene therapies on the near horizon for FDA approval, multidisciplinary teams may improve patient access to these drugs by streamlining approaches towards adapting gene therapies into clinical use.

Summary: The rapid increase in the number of FDA-approved gene therapies has not only created a number of challenges but also opportunities to improve the lives of pediatric patients with rare disorders. The adaptability of physicians, hospitals, and governmental regulatory boards is essential for delivering these new gene therapies safely and efficiently to these rare disease patients. Challenges still remain as to future requirements for additional gene therapy dosing and how to best manage financial burdens placed on the patient and providing institution.

Purpose of review: Primary immune regulatory disorders (PIRDs) are an increasing indication for hematopoietic stem cell transplant (HCT) in pediatric patients. Here, we provide an updated overview of HCT for PIRDs, and discuss future avenues for improvement in outcomes.

Recent findings: There are now more than 50 described monogenic PIRDs, which impact all aspects of immune tolerance, regulation, and suppression. Disease characteristics are highly variable, and HCT remains the only option for cure. We review advances in targeted therapies for individual PIRDs, which have significantly improved outcomes and the ability to safely bridge to transplant. Additionally, advances in GVHD prevention, graft manipulation, personalized conditioning regimens, and supportive care have all increased survival after HCT. The high inflammatory state increases the risk of nonengraftment, rejection, and autologous reconstitution. Therapy to reduce the inflammatory state may further improve outcomes. In addition, although younger patients with fewer comorbidities have better outcomes, the clinical courses of these diseases may be extremely variable thereby complicating the decision to proceed to HCT.

Summary: HCT for PIRDs is a growing consideration in cell therapy. Yet, there remain significant gaps in our understanding of which patients this curative therapy could benefit the most. Here, we review the current data supporting HCT for PIRDs as well as areas for future improvement.

Purpose of review: The aim of the review was to provide an overview of safety and efficacy of the available treatments including information from both clinical trials and real-world data. Additional information form ongoing studies using other approaches than increasing SMN protein are also reported.

Recent findings: In the last 3 years, there have been over 24 studies reporting safety and the impact of the available drugs on different aspects of function, including respiratory and bulbar function. These findings, obtained in a real-world setting, are extremely important to define the spectrum of responses in individuals with different age, weight, SMN2 copies, and other variables and will be of help to the families and the clinicians to set up the right expectations at the time of starting a new treatment.

Summary: The large number of studies that became available in the last few years support and expand the information on safety and efficacy provided by the clinical trials.

Purpose of review: The national workforce shortage in genetics is being evaluated in order to identify a sustainable solution to the increasing demand for genomic services. An innovative solution to the short term needs is to integrate advanced practice providers (APPs) and embed genetic counselors into both outpatient and inpatient specialty care. Incorporating APPs into a genetic service is not unique in itself, but the method of implementation at Medical College of Wisconsin (MCW) was, at the time, unchartered.

Recent findings: There are >100 vacancies for board certified medical geneticists across the nation, training programs are not enrolling sufficient trainees to meet demand and more than a third of the current workforce plan to retire within the next 10 years.

Summary: The integration of advanced practice providers (nurse practitioners, midwives, physician assistants etc.) into both primary and specialty care has been an evolving practice since the mid-1900s and incorporating APPs into a genetic service was not unique in itself but the method of implementation was new at that time. This is a model to successfully develop a clinical practice model around a team-based structure incorporating nurse clinicians, advanced practice providers, genetic counselors, nutritionists, and physicians into an academic clinical genetics practice.

Purpose of review: To highlight the clinical presentation, diagnostic approach, and management of acquired inflammatory demyelinating syndromes in children.

Recent findings: The identification of myelin oligodendrocyte glycoprotein antibody-associated disease in 2017 and evolving evidence regarding best practices for management has had a significant impact on pediatric neuroimmunology, as has the shift in treatment of pediatric-onset multiple sclerosis, with the use of high-efficacy disease-modifying therapies early in the disease course.

Summary: With expanding awareness and growing interest in pediatric onset neuroinflammatory conditions, the number of children diagnosed with acquired demyelinating syndromes is rising. It is critical to refine our understanding of the underlying pathophysiological mechanisms in these disorders to provide the most effective care. Much of our practice continues to be modeled on adult care, and further large-scale pediatric studies are necessary to explore the natural history and assess the safety and efficacy of immunotherapies in childhood-onset demyelinating diseases.
