A confounding pediatric spinal cord injury: Anterior, central, or both?

Pediatric spinal cord injury (SCI) most commonly affects the cervical region. Central cord syndrome most often occurs in the lower cervical injury due to hyperextension injury, while anterior cord syndrome is primarily due to vascular infarction after hyperextension injury. An unusual case of a pediatric patient who physically presented with central cord syndrome but radiologically had evidence of anterior spinal artery syndrome is described. A two-year-old male presented after a fall from three feet with flaccid upper extremities and dysesthesias but maintained functional strength in bilateral lower extremities. Although his clinical presentation was that of central cord syndrome, he was found to have an anterior spinal artery infarct spanning from C2-T3 with a ligamentous injury at C3 and an incidental finding of Chiari I malformation on MRI. Given the negative evaluation for a cardiac or hematologic source of embolus and normal angiography, it was theorized that compression of vertebral arteries by previously undiagnosed Chiari I malformation in the setting of trauma could have made the patient more vulnerable to this complication. During inpatient rehabilitation, he regained scapular movement and shoulder flexion. However, he regained distal movement in supination, wrist extension, and finger flexion instead of the more usual proximal-to-distal motor recovery observed in SCI. While he had a relative sparing of strength in his legs, he had impaired proprioception and balance, leading to gait impairment. This case highlights the complexity of pediatric cervical SCI diagnosis and prognostication. While classic SCI subtypes are well described, many pediatric and adult patients will present and recover in unexpected ways. All with SCI should be evaluated thoroughly for common etiologies and transitioned to rehabilitation therapies to assist in recovery.

Rehabilitation Outcomes in Children With Acute Flaccid Myelitis From 2014 to 2019: A Multicenter Retrospective Review.

BACKGROUND: Acute flaccid myelitis (AFM) is a childhood illness characterized by sudden-onset weakness impairing function. The primary goal was to compare the motor recovery patterns of patients with AFM who were discharged home or to inpatient rehabilitation. Secondary analyses focused on recovery of respiratory status, nutritional status, and neurogenic bowel and bladder in both cohorts. METHODS: Eleven tertiary care centers in the United States performed a retrospective chart review of children with AFM between January 1, 2014, and October 1, 2019. Data included demographics, treatments, and outcomes on admission, discharge, and follow-up visits. RESULTS: Medical records of 109 children met inclusion criteria; 67 children required inpatient rehabilitation, whereas 42 children were discharged directly home. The median age was 5 years (range 4 months to 17 years), and the median time observed was 417 days (interquartile range = 645 days). Distal upper extremities recovered better than the proximal upper extremities. At acute presentation, children who needed inpatient rehabilitation had significantly higher rates of respiratory support (P < 0.001), nutritional support (P < 0.001), and neurogenic bowel (P = 0.004) and bladder (P = 0.002). At follow-up, those who attended inpatient rehabilitation continued to have higher rates of respiratory support (28% vs 12%, P = 0.043); however, the nutritional status and bowel/bladder function were no longer statistically different. CONCLUSIONS: All children made improvements in strength. Proximal muscles remained weaker than distal muscles in the upper extremities. Children who qualified for inpatient rehabilitation had ongoing respiratory needs at follow-up; however, recovery of nutritional status and bowel/bladder were similar.

Can the Ketogenic diet lead to Wernicke's encephalopathy?

BACKGROUND: Wernicke's encephalopathy (WE), a neurological disorder due to the deficiency of thiamine, is often underdiagnosed in the pediatric population. The classic triad of mental status changes, oculomotor abnormality, and ataxia is observed in only 16-21% of all pediatric presentations. Wernicke's is most often associated with alcohol dependence, but also malignancy, parenteral nutrition, and gastrointestinal (GI) malformations. The correlation between following a Ketogenic diet and acquiring Wernicke's, however, has not previously been reported. CASE REPORT: A 16-year-old previously healthy male presented with an eleven-day history of neurological deficits and GI upset. The patient had recently lost one hundred pounds while following a "ketogenic" diet. He was subsequently diagnosed with Wernicke's, received intravenous thiamine, and was transferred to the inpatient rehabilitation, where he received extensive diet education. After making significant functional improvement, he was discharged home. RELEVANCE: This case illustrates the importance of including Wernicke's in the differential diagnosis when a pediatric patient presents with neurological deficits after rapid weight loss. Wernicke's encephalopathy may be fatal in the pediatric population, therefore, it must be treated immediately if clinically suspected. Children presenting with Wernicke's would benefit from early intervention, intensive inpatient rehabilitation, and comprehensive education regarding the role of food and exercise on weight loss and health.

COVID-19 pandemic: Early effects on pediatric rehabilitation medicine training.

PURPOSE: The COVID-19 pandemic hastened the need for graduate medical education (GME) innovation, resulting in the creation of multiple pediatric rehabilitation medicine (PRM) e-learning initiatives. There has been a paucity of data regarding trainee perceptions regarding quickly developed new methods of learning during the pandemic. This study explored PRM trainee perceptions of e-learning and effects of the pandemic on education. METHODS: Questionnaire study with data collected via REDCap. RESULTS: Greater than half of PRM trainees (56.6%, 30/53) responded. Most respondents reported that the virtual lectures series (79.3%), journal club (78.9%), and virtual arts initiatives (75.0%) were valuable to their education. Common benefits noted included access to subject experts, networking, lecture recording, and location flexibility. Common concerns included lack of protected time, virtual platform fatigue, and decreased engagement. Most respondents were not redeployed. Relative to before the pandemic, less satisfaction with clinical education (70.0%) and greater satisfaction with non-clinical education (60.0%) was reported. The majority of graduating trainees felt positively (83.3%) and 16.7% were neutral regarding confidence to graduate. CONCLUSION: Trainees perceived national e-learning as valuable to their education, especially due to the access to expert leaders around the nation. Future work should explore ways to overcome barriers and optimize benefits of GME and PRM e-learning.

Superimposed Guillain-Barré Syndrome (GBS) in pediatric hypoxic brain injury.

BACKGROUND: Hypoxic brain injury results in severe disabilities that require extensive acute inpatient and outpatient rehabilitation to promote maximal functional and cognitive recovery. Brain hypoxemia can result from a multitude of causes, including but not limited to cardiac arrest, drug overdose, and/or shock. While recovery from a hypoxic brain injury alone can be challenging, dealing with concurrent debilitative diagnoses such as Guillain Barré Syndrome (GBS) further complicates the recovery and rehabilitation course. CASE REPORT: The current case study highlights the acute inpatient rehabilitation course of a 16 year old male who presented with cerebral hypoxia secondary to strangulation and subsequently developed GBS. Physical examination of the patient upon rehabilitation consult was inconsistent with a purely hypoxic brain injury, including the absence of rectal tone. This prompted further potential spinal cord injury evaluation and work up, with diagnostic testing confirmatory of GBS. RELEVANCE: This case is important as, to our knowledge from literature review, the first known documented instance of hypoxic brain injury complicated by GBS. Moreover, it highlights the importance of identifying all potential causes of functional disability, particularly when presented with physical exam findings inconsistent with chief diagnosis, in order to maximize functional recovery and rehabilitative gains during acute inpatient rehabilitation.
