RESUMEN
OBJECTIVE: To understand how methylphenidate (MPH) is used in youth with traumatic brain injury (TBI) during inpatient pediatric rehabilitation. SETTING: Inpatient pediatric rehabilitation. PARTICIPANTS: In total, 234 children with TBI; 62 of whom received MPH and 172 who did not. Patients were on average 11.6 years of age (range, 2 months to 21 years); 88 of 234 were female; the most common mechanism of injury was motor vehicle collision (49%); median (IQR) acute hospital length of stay (LOS) and inpatient rehabilitation LOS were 16 (10-29) and 23 (14-39), respectively; 51 of 234 were in a disorder of consciousness cognitive state at time of inpatient rehabilitation admission. DESIGN: Multicenter, retrospective medical record review. MAIN MEASURES: Patient demographic data, time to inpatient pediatric rehabilitation admission (TTA), cognitive state, MPH dosing (mg/kg/day). RESULTS: Patients who received MPH were older (P = .011); TTA was significantly longer in patients who received MPH than those who did not (P =.002). The lowest recorded dose range by weight was 0.05 to 0.89 mg/kg/d, representing an 18-fold difference; the weight-based range for the maximum dose was 0.11 to 0.97 mg/kg/d, a 9-fold difference. Patients in lower cognitive states at admission (P = .001) and at discharge (P = .030) were more likely to receive MPH. Five patients had side effects known to be associated with MPH; no serious adverse events were reported. CONCLUSION: This multicenter study indicates that there is variable use of MPH during acute inpatient rehabilitation for children with TBI. Children who receive MPH tend to be older with lower cognitive states. Dosing practices are likely consistent with underdosing. Clinical indications for MPH use during inpatient pediatric rehabilitation should be better defined. The use of MPH, as well as its combination with other medications and treatments, during inpatient rehabilitation needs to be further explored.

OBJECTIVE: To investigate and characterize the incidence of needlestick injuries (NSI) in a sample of practicing pain medicine physicians, with the ultimate goal of aiding to prevent these injuries by raising awareness of their prevalence. DESIGN: A cross-sectional research survey. SETTING: A REDCap survey was emailed to physicians who had membership to the American Academy of Pain Medicine. SUBJECTS: Eligibility criteria included physicians who were actively practicing and identified as pain physicians who participated in procedures with needlesticks or sharps. METHODS: Basic demographics without identifiers were collected, including practice setting, years in practice, and training type. Respondents were asked to estimate the number of sharps-involved procedure days per week and per day. They were then asked to estimate the number of NSIs they sustained since completing training and in the past year. RESULTS: A total of 430 surveys were opened by email by potential participants, of which 124 responded (response rate 29%). Data from a total of 109 respondents that met inclusion criteria were included. Roughly 60% of respondents reported at least one NSI since completing training and approximately one-third had sustained more than three NSIs. In the last year, roughly 19% of providers reported at least one needlestick injury. The number of NSIs reported by providers since completing training was not significantly associated with practice setting, the number of procedure days per week, or the number of sharps-involved procedures per day. There was a significant relationship between years post-training and number of NSIs since completing training, with providers with more years post-training reporting higher incidences of NSIs (p < 0.0005). The number of NSIs since completing training and the number of NSIs were also associated, with providers that had sustained a greater number of total NSIs reporting a higher incidence of NSIs within the last year (p < 0.0005). CONCLUSIONS: This study characterizes NSIs in a population of pain medicine physicians. These data warrant caution and will hopefully raise awareness amongst providers.

Background: Rehabilitation is the key to management of patients with subacromial impingement syndrome to prevent disability and loss of function. While point-of-care musculoskeletal ultrasound aids clinical diagnosis of subacromial impingement syndrome, many patients do not demonstrate the classic findings of dynamic supraspinatus tendon impingement beneath the acromion on ultrasound. The objective of this study was to establish the most reliable shoulder ultrasound measurements for subacromial impingement, by evaluating the intra-rater and inter-rater reliability of measurements in asymptomatic participants. Methods: Eighteen participants (9 women, 9 men, mean ± standard deviation: 34.6 ± 7.9 years of age) underwent bilateral shoulder ultrasound evaluations with measurements for subacromial impingement (acromiohumeral distance, acromion-greater tuberosity distance, supraspinatus tendon, subacromial-subdeltoid bursa, and subacromial-subdeltoid bursal fluid thickness) performed by two sports medicine physicians. Intra-class coefficients were calculated to determine the intra- and inter-rater reliability of shoulder ultrasound images and measurements. Results: Intra-rater reliability for acromiohumeral distance (0.76-0.79), supraspinatus tendon (0.91-0.95), subacromial-subdeltoid bursa (0.76-0.84), and subacromial-subdeltoid bursal fluid thickness (0.75-0.81) was found to be good to excellent, whereas inter-rater reliability ranged from poor to moderate. Conclusions: Acromiohumeral distance in neutral position and short axis ultrasound measurements of supraspinatus tendon, subacromial-subdeltoid bursa, and subacromial-subdeltoid bursal fluid thickness in the modified Crass position were the most reliable for subacromial impingement in asymptomatic participants. We recommend validation of these measurements in a symptomatic population to aid diagnosis and direct rehabilitation of patients with suspected subacromial impingement, and to increase point-of-care ultrasound uptake, availability, and training among rehabilitation professionals across health systems.
RESUMEN
Patient engagement during inpatient rehabilitation is an important component of rehabilitation therapy, as lower levels of engagement are associated with poorer outcomes. Cognitive deficits may impact patient engagement during inpatient stroke rehabilitation. Here, we assess whether patient performance on the cognitive tasks of the 30-min National Institute of Neurologic Disorders and Stroke - Canadian Stroke Network (NINDS-CSN) screening battery predicts engagement in inpatient stroke rehabilitation. Prospective data from 110 participants completing inpatient stroke rehabilitation at an academic medical center were utilized for the present analyses. Cognitive functioning was assessed at inpatient stroke rehabilitation admission using the NINDS-CSN cognitive battery. Patient engagement was evaluated at discharge from an inpatient rehabilitation unit using the Hopkins Rehabilitation Engagement Rating Scale. The results demonstrate that the NINDS-CSN cognitive battery, specifically subtests measuring executive functioning, attention and processing speed, predicts patient engagement in inpatient stroke rehabilitation. Cognitively impaired patients undergoing rehabilitation may benefit from modifications and interventions to increase engagement and improve functional outcomes.

Background and Objectives: Following severe brain injury, up to 16% of adults showing no clinical signs of cognitive function nonetheless have preserved cognitive capacities detectable via neuroimaging and neurophysiology; this has been designated cognitive-motor dissociation (CMD). Pediatric medicine lacks both practice guidelines for identifying covert cognition and epidemiologic data regarding CMD prevalence. Methods: We applied a diverse battery of neuroimaging and neurophysiologic tests to evaluate 2 adolescents (aged 15 and 18 years) who had shown no clinical evidence of preserved cognitive function following brain injury at age 9 and 13 years, respectively. Clinical evaluations were consistent with minimally conscious state (minus) and vegetative state, respectively. Results: Both participants' EEG, and 1 participant's fMRI, provided evidence that they could understand commands and make consistent voluntary decisions to follow them. Both participants' EEG demonstrated larger-than-expected responses to auditory stimuli and intact semantic processing of words in context. Discussion: These converging lines of evidence lead us to conclude that both participants had preserved cognitive function dissociated from their motor output. Throughout the 5+ years since injury, communication attempts and therapy had remained uninformed by such objective evidence of their cognitive abilities. Proper diagnosis of CMD is an ethical imperative. Children with covert cognition reflect a vulnerable and isolated population; the methods outlined here provide a first step in identifying such persons to advance efforts to alleviate their condition.
RESUMEN
OBJECTIVE: Using stringent inclusion criteria, a double-blinded study protocol, and fluoroscopically guided injections, we compare intra-articular sacroiliac joint platelet-rich plasma injections with intra-articular steroids. DESIGN: Double-blind, randomized controlled trial. SETTING: Two large university-based interdisciplinary spine centers. SUBJECTS: A total of 26 patients with a positive diagnostic block (>80% relief). METHODS: Subjects who had a positive diagnostic block were randomized to undergo either a fluoroscopically guided intra-articular injection of steroid or a platelet-rich plasma injection. Follow-up was at 1 month, 3 months, and 6 months. Outcomes included level of pain, as indicated on a 0- to 100-mm numeric pain rating scale, and functional disability score, obtained via the Oswestry Disability Index (ODI). RESULTS: At 1, 3, and 6 months, both groups improved; however, subjects who received steroid injections reported lower pain scores than did subjects who received platelet-rich plasma. Using categorical data, we observed significantly more responders (defined as pain scores that improved by 50% or more from baseline) at 1 and 3 months in the group who received steroids than in the group who received platelet-rich plasma. CONCLUSION: Although both groups showed improvements in pain and function, the steroid group had significantly greater response and significantly more responders than did the platelet-rich plasma group.

OBJECTIVES: To describe dosing practices for amantadine hydrochloride and related adverse effects among children and young adults with traumatic brain injury (TBI) admitted to pediatric inpatient rehabilitation units. SETTING: Eight pediatric acute inpatient rehabilitation units located throughout the United States comprising the Pediatric Brain Injury Consortium. PARTICIPANTS: Two-hundred thirty-four children and young adults aged 2 months to 21 years with TBI. DESIGN: Retrospective data revie. MAIN OUTCOME MEASURES: Demographic variables associated with the use of amantadine, amantadine dose, and reported adverse effects. RESULTS: Forty-nine patients (21%) aged 0.9 to 20 years received amantadine during inpatient rehabilitation. Forty-five percent of patients admitted to inpatient rehabilitation with a disorder of consciousness (DoC) were treated with amantadine, while 14% of children admitted with higher levels of functioning received amantadine. Children with DoC who were not treated with amantadine were younger than those with DoC who received amantadine (median 3.0 vs 11.6 years, P = .008). Recorded doses of amantadine ranged from 0.7 to 13.5 mg/kg/d; the highest total daily dose was 400 mg/d. Adverse effects were reported in 8 patients (16%); nausea/abdominal discomfort and agitation were most common, each reported in 3 patients. The highest reported dose without an adverse effect was 10.1 mg/kg/d. CONCLUSION: During pediatric inpatient rehabilitation, amantadine was prescribed to children across a range of ages and injury severity and was most commonly prescribed to older children with DoC. Dosing varied widely, with weight-based dosing for younger/smaller children at both lower and higher doses than what had been previously reported. Prospective studies are needed to characterize the safety and tolerability of higher amantadine doses and optimize amantadine dosing parameters for children with TBI.

OBJECTIVE: Little is known about the underlying neurophysiology of pediatric delirium. In adult patients, the sensitivity of EEG to clinical symptoms of delirium has been noted, with a slowing of background activity (alpha) and an increase in slow-wave activity (delta-theta). In this pilot study, the authors extended this investigation to a pediatric cohort. METHODS: In a convenience sample, 23 critically ill children were screened for delirium, using the Cornell Assessment for Pediatric Delirium (CAPD), every 12 hours throughout their pediatric intensive care unit stay as part of standard intensive care unit procedure, and EEGs were performed as part of their clinical care. After hospital discharge, EEGs were reviewed using quantitative analysis, and the maximum delta-alpha ratio (DAR; eyes closed) was derived for each 12-hour period. DAR values were compared between delirious and nondelirious episodes, and the linear relationship between DAR and CAPD was assessed. RESULTS: Higher DARs were associated with episodes of delirium. The DAR also positively correlated with CAPD assessments, with higher DARs relating to higher delirium scores. CONCLUSIONS: Future prospective studies may further investigate this relationship in a more homogeneous and larger sample, and the DAR should be considered to track delirium and assess the effectiveness of therapeutic interventions.

PURPOSE OF REVIEW: Cognitive impairments are a devastating long-term consequence following traumatic brain injury (TBI). This review provides an update on the quantitative mutimodal neuroimaging studies that attempt to elucidate the mechanism(s) underlying cognitive impairments and their recovery following TBI. RECENT FINDINGS: Recent studies have linked individual specific behavioural impairments and their changes over time to physiological activity and structural changes using EEG, PET and MRI. Multimodal studies that combine measures of physiological activity with knowledge of neuroanatomical and connectivity damage have also illuminated the multifactorial function-structure relationships that underlie impairment and recovery following TBI. SUMMARY: The combined use of multiple neuroimaging modalities, with focus on individual longitudinal studies, has the potential to accurately classify impairments, enhance sensitivity of prognoses, inform targets for interventions and precisely track spontaneous and intervention-driven recovery.

BACKGROUND: Genicular nerve block and subsequent radiofrequency neurotomy (RFN) has emerged as a novel intervention and alternative for total knee arthroplasty in patients with refractory pain from knee osteoarthritis (OA). To our knowledge, there is no cited report correlating the accuracy of localizing the genicular nerves using bony landmarks on magnetic resonance imaging (MRI). OBJECTIVES: To quantify the proximity of superomedial genicular nerve (SMGN), superolateral genicular nerve (SLGN), and inferomedial genicular nerve (IMGN) from a target point. The target point was an intersection marked by a line parallel to the diaphysis and a separate line parallel to the metaphyseal flare along the cortical surfaces of both the femur and tibia. DESIGN: Retrospective chart review. PATIENTS: A total of 25 de-identified knee MRIs were reviewed. METHODS: The coronal proton density fat suppressed sequence was used for identification and localization of the SLGN, SMGN, and IMGN. The neurovascular bundles were traced from posterior location along their origin as they wrap around the distal diaphysis. The nerve locations were determined by consensus measurements performed by two board-certified radiologists with certificates of added qualification in neuroradiology and interventional radiology. The proximity of each respective genicular nerves was measured by drawing a perpendicular line from each genicular nerve to the height of the target point. All measurements were taken on the mid-coronal view at the point of maximal epiphyseal flare. MAIN OUTCOME MEASUREMENTS: Positive values indicated the location of the neurovascular bundle to be superior to the target point. Negative values indicated the location of the neurovascular bundle to be inferior to the target point. RESULTS: The distance between our target point and the inferior border of SLGN ranged from -3â¯mm to 6â¯mm. Twenty-three out of 25 (92%) SLGN lied exactly at or above our target intersection. The distance between our target point and the inferior border of SMGN ranged from -1â¯mm to 2â¯mm with twenty-two out of 25 (88%) SMGN lied exactly at or above our target point. The distance between our target point and the superior border of IMGN ranged from 0â¯mm to 3â¯mm with all (100%) IMGN lying exactly at or above the target point. CONCLUSION: The intersection of the femoral diaphyseal shaft to a line along the metaphyseal flare and the intersection of the tibial diaphyseal shaft to a line along the medial metaphyseal can be used as a target point to localize the genicular nerves with close proximity.
