Early MRI Can Predict the Indication for Surgery in Brachial Plexus Birth Injury: Results of the NAPTIME Study.

Background: Magnetic resonance imaging (MRI) has not been routinely used for infants with brachial plexus birth injury (BPBI); instead, the decision to operate is based on the trajectory of clinical recovery by 6 months of age. The aim of this study was to develop an MRI protocol that can be performed without sedation or contrast in order to identify infants who would benefit from surgery at an earlier age than the age at which that decision could be made clinically.

Methods: This prospective multicenter NAPTIME (Non-Anesthetized Plexus Technique for Infant MRI Evaluation) study included infants aged 28 to 120 days with BPBI from 3 tertiary care centers.

Surface electromyography evaluation for decoding hand motor intent in children with congenital upper limb deficiency.

Children born with congenital upper limb absence exhibit consistent and distinguishable levels of biological control over their affected muscles, assessed through surface electromyography (sEMG). This represents a significant advancement in determining how these children might utilize sEMG-controlled dexterous prostheses. Despite this potential, the efficacy of employing conventional sEMG classification techniques for children born with upper limb absence is uncertain, as these techniques have been optimized for adults with acquired amputations.

Health-related quality of life in 205 children with arthrogryposis multiplex congenita.

Purpose: Arthrogryposis multiplex congenita (AMC) describes a heterogeneous group of rare congenital conditions. Health-related quality of life (HRQL) may be reduced in AMC due to broadly heterogeneous physical impairments and participation limitations. This study described HRQL in children and youth with AMC, compared HRQL between child self- and parent-proxy reports, and identified factors associated with better/worse HRQL.

Relationship of TAPSE Normalized by Right Ventricular Area With Pulmonary Compliance, Exercise Capacity, and Clinical Outcomes.

Background: While tricuspid annular plane systolic excursion (TAPSE) captures the predominant longitudinal motion of the right ventricle (RV), it does not account for ventricular morphology and radial motion changes in various forms of pulmonary hypertension. This study aims to account for both longitudinal and radial motions by dividing TAPSE by RV area and to assess its clinical significance.

Methods: We performed a retrospective analysis of 71 subjects with New York Heart Association class II to III dyspnea who underwent echocardiogram and invasive cardiopulmonary exercise testing (which defined 4 hemodynamic groups: control, isolated postcapillary pulmonary hypertension, combined postcapillary pulmonary hypertension, and pulmonary arterial hypertension).

Understanding the capacity of children with congenital unilateral below-elbow deficiency to actuate their affected muscles.

In recent years, commercially available dexterous upper limb prostheses for children have begun to emerge. These devices derive control signals from surface electromyography (measure of affected muscle electrical activity, sEMG) to drive a variety of grasping motions. However, the ability for children with congenital upper limb deficiency to actuate their affected muscles to achieve naturalistic prosthetic control is not well understood, as compared to adults or children with acquired hand loss.

Moving a missing hand: children born with below elbow deficiency can enact hand grasp patterns with their residual muscles.

Children with a unilateral congenital below elbow deficiency (UCBED) have one typical upper limb and one that lacks a hand, ending below the elbow at the proximal/mid forearm. UCBED is an isolated condition, and affected children otherwise develop normal sensorimotor control. Unlike adults with upper limb absence, the majority of whom have an acquired loss, children with UCBED never developed a hand, so their residual muscles have never actuated an intact limb.

Neuromuscular Dysfunction in Clubfeet Associated With Constriction Band Syndrome.

Introduction: Constriction band syndrome (CBS) is a congenital limb anomaly frequently associated with clubfoot. Clubfeet in CBS patients may be associated with peroneal nerve dysfunction in the involved lower extremity; however, the etiology of this neuromuscular dysfunction is not clear. We sought to characterize the distribution of constriction bands on lower extremities with clubfoot and determine if neuromuscular deficit (NMD), defined here as having absent ankle dorsiflexion, was associated with ipsilateral proximal bands.

The Green Transfer-Long-Term Results.

Purpose: The purpose of this study was to determine the long-term results of the Green transfer (flexor carpi ulnaris to extensor carpi radialis brevis) for patient-reported outcomes, wrist position, and range of motion.

Methods: We re-examined 13 patients from a previous prospective study involving surgery for hemiplegia that included a Green transfer. The average follow-up was 8 years with the range from 5 to 11 years.

Review and critique of current testing protocols for upper-limb prostheses: a call for standardization amidst rapid technological advancements.

This article provides a comprehensive narrative review of physical task-based assessments used to evaluate the multi-grasp dexterity and functional impact of varying control systems in pediatric and adult upper-limb prostheses. Our search returned 1,442 research articles from online databases, of which 25 tests-selected for their scientific rigor, evaluation metrics, and psychometric properties-met our review criteria. We observed that despite significant advancements in the mechatronics of upper-limb prostheses, these 25 assessments are the only validated evaluation methods that have emerged since the first measure in 1948.

Association of Parity and Previous Birth Outcome With Brachial Plexus Birth Injury Risk.

Objective: To evaluate the association of maternal delivery history with a brachial plexus birth injury risk in subsequent deliveries and to estimate the effect of subsequent delivery method on brachial plexus birth injury risk.

Methods: We conducted a retrospective cohort study of all live-birth deliveries occurring in California-licensed hospitals from 1996 to 2012. The primary outcome was recurrent brachial plexus birth injury in a subsequent pregnancy.

Team Approach: The Care of Children with Hand and Upper Limb Differences.

» Pediatric hand and upper limb differences include a wide range of conditions that may be genetic, part of a syndrome, or arise from birth trauma or an unknown cause.» Because of the variety of conditions and complexity of care requiring professionals from multiple disciplines, the Pediatric Hand Team is similar in purpose to the coordinated multidisciplinary care provided by Craniofacial Panels for children with craniofacial anomalies. Pediatric hand surgeons are trained to lead and coordinate the care of children with these differences, and the Pediatric Hand Team includes occupational and/or certified hand therapists, child life specialists, geneticists and genetic counselors, prosthetists and orthotists, pediatric physical medicine and rehabilitation physicians, pediatric orthopaedic surgeons, pediatric anesthesiologists, and social workers and psychologists.

Comparison of Different Methods of Measuring Finger Range of Motion via Telehealth.

Purpose: This study examined the accuracy and reliability of measuring total motion of the fingers via telehealth using the following three different methods: (1) goniometry, (2) visual estimation, and (3) electronic protractor. Measurements were compared with in-person measurement, which was assumed to be the reference standard.

Methods: Thirty clinicians measured finger range of motion from prerecorded videos of a mannequin hand with articulating fingers, which was posed in extension and flexion that simulated a telehealth visit, using a goniometer with results blinded to the clinician (blinded goniometry), visual estimation, and an electronic protractor, in random order.

Dyspnea induced by inspiratory loading limits dual-tasking in healthy young adults.

Objectives: Dyspnea is a common and multidimensional experience of healthy adults and those with respiratory disorders. Due to its neural processing, it may limit or interfere with cognition, which may be examined with a dual-task paradigm. The aim of this study was to compare single-task performance of Stroop Colour and Word Test (SCWT) or inspiratory threshold loading (ITL) to their combined dual-task performance.

Maternal Epidemiology of Brachial Plexus Birth Injuries in California: 1996 to 2012.

Objective: This study aimed to evaluate the incidence of brachial plexus birth injury (BPBI) and its associations with maternal demographic factors. Additionally, we sought to determine whether longitudinal changes in BPBI incidence differed by maternal demographics.

Study Design: We conducted a retrospective cohort study of over 8 million maternal-infant pairs using California's Office of Statewide Health Planning and Development Linked Birth Files from 1991 to 2012.

Do Nails and Nubbins Matter? A Comparison of Symbrachydactyly and Transverse Deficiency Phenotypes.

Purpose: Transverse deficiency (TD) and symbrachydactyly may be difficult to distinguish due to shared phenotypes and a lack of pathognomonic features. The 2020 Oberg-Manske-Tonkin classification update modified these anomalies to include "with ectodermal elements" for symbrachydactyly and "without ectodermal elements" for TD as a defining differentiating characteristic. The purpose of this investigation was to characterize ectodermal elements and the level of deficiency and to examine whether ectodermal elements versus the level of deficiency was a greater determining factor for Congenital Upper Limb Differences (CoULD) surgeons making the diagnosis.

Self-concept development in children with limb differences: A scoping review.

Having a visible physical difference, such as a limb difference, can have a significant impact on a child's psychosocial development, as children with limb differences may experience negative psychosocial sequelae. The aim of this scoping review was to investigate the findings of literature pertaining to self-concept of children with limb differences. Using the PRISMA ScR guidelines, a literature search was conducted in Embase, CINAHL, PsycINFO and PubMed databases.

Reliability of the Masada Classification for Forearm Involvement in Patients With Hereditary Multiple Osteochondromas (HMO).

Background: Classifications describing forearm lesions in patients with Hereditary Multiple Osteochondromatosis (HMO) have been used to recommend surgical intervention and stratify outcomes; however, there is no consensus on which classification offers greater reliability. The purpose of this study was to determine the reliability of the Masada classification and newer classifications among pediatric hand surgeons.

Methods: One hundred one patients with HMO between June 2014 and October 2019 were enrolled in the Congenital Upper Limb Differences (CoULD) Registry.

Aerosolized Hydrogen Peroxide Decontamination of N95 Respirators, with Fit-Testing and Viral Inactivation, Demonstrates Feasibility for Reuse during the COVID-19 Pandemic.

In response to the demand for N95 respirators by health care workers during the COVID-19 pandemic, we evaluated decontamination of N95 respirators using an aerosolized hydrogen peroxide (aHP) system. This system is designed to dispense a consistent atomized spray of aerosolized, 7% hydrogen peroxide (HO) solution over a treatment cycle. Multiple N95 respirator models were subjected to 10 or more cycles of respirator decontamination, with a select number periodically assessed for qualitative and quantitative fit testing.

Patient-reported Outcomes for Children With Unilateral Congenital Below Elbow Deficiency.

Background: The Patient Reported Outcomes Measurement Information System (PROMIS ® ) is a validated tool used to evaluate different domains of function in patients with chronic health conditions. This tool has not been validated in children with unilateral congenital below elbow deficiency (UCBED). The purpose of this study was to determine whether PROMIS discerns functional impairment for children with UCBED and whether children with UCBED differ from the general population with respect to PROMIS outcomes.

Clinical Manifestations of Constriction Band Syndrome.

Background: Constriction band syndrome (CBS) is a congenital limb anomaly with varying presentation. We sought to characterize the clinical manifestations of CBS by analyzing a large cohort of patients. Our secondary aim was to evaluate potential risk factors for CBS.

Effects of Semaglutide on Stroke Subtypes in Type 2 Diabetes: Post Hoc Analysis of the Randomized SUSTAIN 6 and PIONEER 6.

Background: GLP-1 RA (glucagon-like peptide-1 receptor agonists), including semaglutide, may reduce stroke risk in people with type 2 diabetes. This post hoc analysis examined the subcutaneous and oral semaglutide effects, versus placebo, on stroke and its subtypes in people with type 2 diabetes at high cardiovascular risk.

Methods: SUSTAIN 6 (Trial to Evaluate Cardiovascular and Other Long-Term Outcomes With Semaglutide in Subjects With Type 2 Diabetes) and PIONEER 6 (Peptide Innovation for Early Diabetes Treatment) were randomized cardiovascular outcome trials of subcutaneous and oral semaglutide in people with type 2 diabetes at high cardiovascular risk, respectively.

Perfusion Imaging for Endovascular Thrombectomy in Acute Ischemic Stroke Is Associated With Improved Functional Outcomes in the Early and Late Time Windows.

Background: The impact on clinical outcomes of patient selection using perfusion imaging for endovascular thrombectomy (EVT) in patients with acute ischemic stroke presenting beyond 6 hours from onset remains undetermined in routine clinical practice.

Methods: Patients from a national stroke registry that underwent EVT selected with or without perfusion imaging (noncontrast computed tomography/computed tomography angiography) in the early (<6 hours) and late (6-24 hours) time windows, between October 2015 and March 2020, were compared. The primary outcome was the ordinal shift in the modified Rankin Scale score at hospital discharge.

Association between anesthesia modality and clinical outcomes following endovascular stroke treatment in the extended time window.

Background: There is a paucity of data on anesthesia-related outcomes for endovascular treatment (EVT) in the extended window (>6 hours from ischemic stroke onset). We compared functional and safety outcomes between local anesthesia (LA) without sedation, conscious sedation (CS) and general anesthesia (GA).

Methods: Patients who underwent EVT in the early (<6 hours) and extended time windows using LA, CS, or GA between October 2015 and March 2020 were included from a UK national stroke registry.
