Initial Validation of GRASP: A Differential Diagnoses Algorithm for Children With Medical Complexity and an Unknown Source of Pain

Challenging Case: A Multidisciplinary Approach to Demystifying Chronic Sleep Impairment in an Infant with a Complex Medical and Behavioral Profile

CASE

X is a 22-month-old White male infant with a complex medical history, including diagnoses of FBXO11 mutation, hypotonia, restrictive lung disease and mild intermittent asthma, laryngotracheomalacia, obstructive sleep apnea (OSA), feeding difficulties with a history of aspiration, gastroesophageal reflux disease (GERD), and developmental delays. X's medical presentation has resulted in multiple prior medical admissions for respiratory failure due to acute illnesses, procedures and treatments including gastrojejunostomy (GJ) tube dependence, supraglottoplasty to reshape tissues of the upper larynx, and the use of biphasic positive airway pressure (BiPAP) at night and room air during the day when he is at baseline. In addition, he has nocturnal events characterized by significant agitation, screaming, crying, body stiffening and limb movements with pauses in breathing, mouth breathing, restless sleep, and difficulty waking in the morning with concomitant daytime fatigue despite above treatments for OSA. There is no history of congenital heart disease or sudden unexplained death. Family history is noncontributory because parents are negative for the FBXO11 variant.X's sleep disruption has led to significant sleep deficits for both X and his caregivers, who spend much of the night strategizing on how to console him. X has undergone several sleep studies, starting when X was aged 4 months, at several children's hospitals across the nation to determine the cause of his chronic sleep disturbance, which yielded limited information and treatment success. As an infant, X received a medical workup and was subsequently treated with a proton pump inhibitor (PPI) for reflux. At 12 months, he was diagnosed with disordered sleep with myoclonic jerks and started on melatonin and gabapentin for involuntary movements. At 13 months, gabapentin was weaned back because of intolerance, and at 15 months, nortriptyline and clonidine were started because of worsening symptoms to target potential neuropathic pain. While most of his symptoms were at night, he had occasional daytime screaming episodes, particularly when experiencing illness. Gabapentin and clonidine were stopped because nortriptyline seemed most effective.At 17 months, the results from a sleep study led to a diagnosis of night terrors, and several clinicians agreed that X's sleep disruption was behavioral in nature. At this time, an infant mental health consultant met with a sleep psychologist on the family's behalf to support family in considering systematic desensitization therapy to increase tolerance to wearing his BiPAP mask, as well as other behavioral and sleep hygiene strategies, which were tried on several occasions and again, resulted in limited improvement in functioning.At 19 months, X's multidisciplinary team reconsidered a night terror diagnosis after a failed trial of clonazepam and pursued a differential diagnosis of periodic limb movement disorder (PLMD). X trialed gabapentin again, but this time only a nighttime dose, per sleep medicine and psychiatry recommendation. While this brought some temporary relief from nighttime distress, despite increasing to the highest dose for age and weight (15 mg/kg/dose), this became less effective, and he was weaned off at 22 months. He had been on iron supplementation since age 6 months and received an iron infusion at 22 months because of persistently low ferritin levels and PLMD in sleep.At 24 months, X was briefly trialed on levetiracetam. While no evidence for seizures on EEG was present, this medication was chosen for involuntary movements and genetic risk for seizures. However, this medication was not useful. At 25 months, an evaluation with a movement disorder physiatrist resulted in a diagnosis of nocturnal paroxysmal dystonia, and he was started on baclofen, which has provided some, but not complete relief to nighttime symptoms. Parents are reporting he has more "good nights" than "bad nights," but "bad nights" come in stretches of a few days in length with no known trigger or relief.Most recently, X was evaluated by general genetics. Whole exome sequencing (WES) was pursued which revealed a pathogenic de novo variant in FBXO11 and provides a likely cause for his neurodevelopmental phenotype. However, he has some features not explained by FBX011; thus, reanalysis of his WES was performed and revealed a de novo variant of uncertain significance in RAF1. Because pathogenic variants in RAF1 have been associated with dilated cardiomyopathy and Noonan spectrum disorder, it was recommended that X be followed periodically in a cardiac genetics clinic. Family is well connected into the FBXO11 community, including supportive Facebook groups. Parents have shared that they do not feel X's breathing issues and pain fit with the phenotype of other children with FBXO11 mutations.X is also enrolled in a medical child care program to facilitate development and social-emotional functioning and receives learning, speech, occupational, physical, and feeding therapy while in attendance. Despite periods of absence due to contracting numerous viral illnesses over the past several months, X continues to make progress across developmental therapies and happily engages when at the program.What additional diagnostic tests and treatment should be considered to better understand X's medical and behavioral presentation? What are the implications of chronic sleep deprivation and stress on the behavior and development of infant with X's profile? What are important psychosocial considerations because it relates to children with medical complexity (CMC), particularly for X and his family to support caregiver, family, and X's quality of life and overall well-being?

Relevance of Potential Contributing Factors for the Development and Maintenance of Irritability of Unknown Origin in Pediatric Palliative Care

Potential contributing factors (PCFs) for irritability of an unknown origin (IUO) in children with neurological conditions are identifiable through structured diagnostics. Uncertainty exists regarding the actual relevance of identified PCFs to IUO. Assessments from parents as well as nursing, psycho-social, and medical professionals were used to determine the contribution of different PCFs in the development and maintenance of IUO. For this, individual PCFs of N = 22 inpatient children with IUO were presented to four raters. Descriptive statistics, Kruskal-Wallis tests, and Krippendorff's alpha were used to determine which PCFs were most relevant to explain IUO and rater agreement. Psycho-social aspects (44.7%), hyperarousal (47.2%), pain (24.6%), and dystonia (18.1%) were identified as the most relevant PCFs for IUO. Descriptively, physicians' relevance rating regarding psycho-social aspects, hyperarousal, and dystonia deviated the most from the overall group rating. All professional raters considered psycho-social aspects to be more relevant than did parents. Parents rated pain as more relevant than the other raters. Kruskal-Wallis tests showed no significant differences between relevance ratings (H = 7.42, p = 0.059) or the four parties' deviations (H = 3.32, p = 0.344). A direct comparison of the six two-party constellations showed that across all factors, agreement was weak to moderate. The highest agreement was between physicians and nurses (α = 0.70), and the lowest was between nurses and psycho-social experts (α = 0.61). Understanding which psycho-social and various biological PCFs are significant for IUO can facilitate more targeted and individualized pediatric palliative care for affected patients.

Interprofessional Collaboration Improves Quality of Life of a Young Adult With Rett Syndrome

Rett syndrome (RTT) is a genetic neurodevelopmental disease characterized by early normal development followed by regression in motor and language skills. Patients with RTT often exhibit seizure disorders, growth failure, heart and lung disorders, bruxism, and dental caries. We report on a female patient in her 20s with Rett syndrome who presented to her primary care clinic with increasing agitation and pain. This case reports describes a collaborative, interprofessional approach between medical and dental providers who work in an integrated outpatient setting. It demonstrates that interprofessional collaboration, goals of care discussions, and attention to social drivers of health can improve quality of life for a medically and socially complex patient.

Potential Contributing Factors for Irritability of Unknown Origin in Pediatric Palliative Care

CONTEXT

In pediatric palliative care, irritability of unknown origin (IUO) in children with severe neurological impairment is a peculiarly complex and challenging symptom, yet its etiology remains poorly understood.

OBJECTIVES

Presenting a structured IUO diagnostic and therapeutic approach developed in a specialized inpatient pediatric palliative care facility for identifying IUO's potential contributing factors (PCFs).

METHODS

Prospective observational study with N = 22 children showing IUO at admission to the inpatient pediatric palliative care facility. Analysis of patient records and participation in ward routine to identify and treat PCFs. Treatment outcome was assessed using a standardized protocol for tracking IUO at 24-hour intervals.

RESULTS

Altogether, 136 PCFs were identified (average 6.18 per child) with pain and psycho-social problems being the most common. Two hundred and twenty-two diagnostic measures were initiated of which 159 (71.6%) helped identify a PCF. The majority of PCFs were identified by basic diagnostics (93.7%). Inpatient length of stay and duration of IUO phases correlated significantly. Between baseline (days 3-5; timing at which inpatients experientially show regular behavior) and discharge, patients showed a significant reduction in average 24-hours IUO duration by 1 hour and 26 minutes (Wilcoxon test: Z = -3.29, P < 0.01).

CONCLUSION

Results lead to a more thorough understanding of PCFs to IUO. Following a systematic approach such as the one presented, PCFs can be detected even by simple diagnostics. In addition to biological aspects, diagnostics and therapy should address psycho-social aspects of IUO.

Evaluation of Pain in Adults With Childhood-Onset Disabilities and Communication Difficulties

Adults with childhood-onset disabilities, particularly those with central nervous system impairment, commonly experience pain. Because many such individuals have difficulties in communication, caregivers and medical professionals must identify and interpret non-verbal behaviors as indicators of pain. This process is challenging and can lead to poor outcomes through delayed or incorrect diagnosis and treatment. Most research in the evaluation of pain in individuals with neurologic impairment has focused on the pediatric population, and evidence-based guidelines do not exist for adults. The purpose of this paper is to review current recommendations for pain assessment in adults with communication impairment. This approach includes guidance for history-taking, pharmacologic review, physical examination, and the judicious use of laboratory and imaging tests. Finally, we discuss adult-specific diagnoses to consider when evaluating pain in adults with childhood-onset disabilities and communication difficulties.

Association between depression, anxiety, and insomnia with musculoskeletal pain source: a multi-center study

Background

Musculoskeletal pain syndrome (MPS) is one of the modern diseases. Musculoskeletal pain (MP) may develop at any age and impact physical and mental health. This study aimed to evaluate the association between anxiety, depression, and insomnia with musculoskeletal pain source. This cross-sectional study was conducted on 450 patients with musculoskeletal pain. Goldberg depression (GB), Beck Anxiety Inventory (BAI), and Morin Insomnia Severity Index (ISI) questionnaires were used to collect data. Participants have divided into two groups: individuals with unknown musculoskeletal pain sources and individuals with known musculoskeletal pain sources. Anxiety, depression, and insomnia scores were compared between the two groups. For statistical analysis of data mean (SD), frequency (%), Chi-square, Mann-Whitney test, and Logistic regression models were used. All analysis was performed using SPSS 26.

Results

In this study, 39.4% of the participants were in severe depression, 31.1% in severe anxiety, 34.7% in the no clinically significant, and 32.9% in the sub-threshold insomnia group. There was a significant difference between the severity of anxiety and insomnia in the two groups with the known and unknown pain sources (p < 0.05). However, the score of depression (OR = 1.00, 95% CI 0.99–1.01), anxiety (OR = 1.00, 95% CI 0.99–1.02), and insomnia (OR = 1.01, 95% CI 0.98–1.03) was not related to the pain source.

Conclusion

There was a statistically significant relationship between anxiety and insomnia severity with musculoskeletal pain source. According to the high prevalence of depression, anxiety, and depression in both groups with known and unknown musculoskeletal pain sources, the cooperation of orthopedists, rheumatologists, and physical therapists with psychiatrist can be useful in improving the condition of patients.

Leveraging Parent Pain Perspectives to Improve Pain Practices for Children with Medical Complexity

PURPOSE

Children with medical complexity (MC) must rely on others to notice and address pain. Parents are aware of child pain behaviors and can serve as reliable proxy reporters. Thus, there is a critical need to understand parent perspectives to improve pain practices.

DESIGN

Individual interviews were used as a data collection method in this qualitative study.

METHODS

Participants were recruited via mail and social media postings. Interviews were audio-recorded and transcribed verbatim. Transcribed documents were imported to NVIVO for qualitative analysis. Conventional and directed approaches to qualitative content analysis were used.

RESULTS

From the data analysis, major themes included: pain experiences, confidence in caregivers, parents are partners, proactive communication, and a spontaneous theme, "they can hear us." Emotional pain and challenges identifying the source pain were identified as sub-themes of pain experiences.

CONCLUSIONS

Parents in this study shared methods helpful to identifying pain in their children, as well as suggestions for discussing pain with caregivers. Priorities for future research include identifying methods for sharing pain information that are thorough, but do not burden parents or providers. Researchers should also determine how parents and caregivers can partner to identify and address pain in children with MC. Going forward, conversations about pain should be a key part of any admission assessment or first encounter. As pain episodes among children with MC can be complex and may not always be re-created in front of a provider, nurses may advise parents to take photos or videos to share with caregivers.
