ABSTRACT

Coronavirus disease 2019 has become a widespread public health crisis across the globe, requiring multiple approaches to containment, treatment, and prevention. Vaccines are an important tool to prevent morbidity and mortality from this devastating virus. Ensuring direct administration of vaccines into target tissue helps provide an optimal immune response while decreasing unintended adverse effects. Point-of-care ultrasound can better assist clinicians to determine appropriate needle length and penetration level especially in special populations. Examples include patients who are obese, pregnant, or with refractory lymphedema, and those living in areas where needle supply is unstable or insufficient.

ABSTRACT

PURPOSE: To investigate the effects of Pilates exercise on improving health-related quality of life in people living with chronic low back pain. METHODS: This was a single-blind, randomised clinical trial. Thirty-nine physically active subjects aged between 30 and 70 years with nonspecific chronic low back pain for more than three months were recruited. The study employed a pretest-posttest design, with a 4 -, 8 -, and 26-week follow-up. For eight weeks, the intervention group participated in a group-supervised, mat-based Pilates program, while the control group received the usual pharmacologic and rehabilitation standard of care, including patient education on chronic low back pain. The primary outcome was self-perceived health status measured using the EQ-5D questionnaire in a structured form and a visual analogue scale. Secondary outcomes included intensity of pain and degree of disability. RESULTS: By the end of the 8-week Pilates program, the intervention group achieved a better health-related quality of life on the EQ-5D visual analogue score than the control group. In assessing the trends in each individual group regarding pain, the intervention group demonstrated an earlier pain reduction than the control group that lasted until the end of the trial. CONCLUSIONS: An 8-week supervised Pilates-based core exercise program is an effective therapeutic modality for improving self-perceived health status in patients with chronic low back pain. This finding could inform clinicians of better alternatives when they suggest exercise interventions for chronic low back pain.

ABSTRACT

A promising new approach, transcranial direct current stimulation (tDCS) has recently been used as a therapeutic modality for cerebellar ataxia. However, the strength of the conclusions drawn from individual studies in the current literature may be constrained by the small sample size of each trial. Following a systematic literature retrieval of studies, meta-analyses were conducted by pooling the standardized mean differences (SMDs) using random-effects models to assess the efficacy of tDCS on cerebellar ataxia, measured by standard clinical rating scales. Domain-specific effects of tDCS on gait and hand function were further evaluated based on 8-m walk and 9-hole peg test performance times, respectively. To determine the safety of tDCS, the incidences of adverse effects were analyzed using risk differences. Out of 293 citations, 5 randomized controlled trials involving a total of 72 participants with cerebellar ataxia were included. Meta-analysis indicated a 26.1% (p = 0.003) improvement in ataxia immediately after tDCS with sustained efficacy over months (28.2% improvement after 3 months, p = 0.04) when compared with sham stimulation. tDCS seems to be domain-specific as the current analysis suggested a positive effect on gait (16.3% improvement, p = 0.04) and failed to reveal differences for hand function (p = 0.10) with respect to sham. The incidence of adverse events in tDCS and sham groups was similar. tDCS is an effective intervention for mitigating ataxia symptoms with lasting results that can be sustained for months. This treatment shows preferential effects on gait ataxia and is relatively safe.

ABSTRACT

BACKGROUND: Dysphagia is a common symptom and may be a cause of death in patients with spinocerebellar ataxias (SCAs). However, little is known about at which disease stage dysphagia becomes clinically relevant. Therefore, our study aims to investigate the prevalence of dysphagia in different disease stages of SCA 1, 2, 3 and 6. METHODS: We studied 237 genetically confirmed patients with SCA 1, 2, 3, 6 from the Clinical Research Consortium for SCAs and investigated the prevalence of self-reported dysphagia and the association between dysphagia and other clinical characteristics. We further stratified ataxia severity and studied the prevalence of dysphagia at each disease stage. RESULTS: Dysphagia was present in 59.9% of SCA patients. Patients with dysphagia had a longer disease duration and more severe ataxia than patients without dysphagia (patients with dysphagia vs. without dysphagia, disease duration (years): 14.51 ± 8.91 vs. 11.22 ± 7.82, p = .001, scale for the assessment and rating of ataxia [SARA]: 17.90 ± 7.74 vs. 13.04 ± 7.51, p = .000). Dysphagia was most common in SCA1, followed by SCA3, SCA 6, and SCA 2. Dysphagia in SCA1 and 3 was associated robustly with ataxia severity, whereas this association was less obvious in SCA2 and 6, demonstrating genotype-specific clinical variation. CONCLUSION: Dysphagia is a common clinical symptom in SCAs, especially in the severe disease stage. Understanding dysphagia in SCA patients can improve the care of these patients and advance knowledge on the roles of the cerebellum and brainstem control in swallowing.

ABSTRACT

OBJECTIVE: Glenohumeral joint hydrodilatation with corticosteroids has been proposed as an effective secondary therapeutic procedure for primary adhesive capsulitis. However, little is known about which subgroup of patients would benefit from this procedure. This study aimed to identify covariates associated with improved prognosis in patients receiving ultrasound-guided hydrodilatation with corticosteroid injection. DESIGN: This was a cohort study. Data on baseline demographic characteristics, disease status, past medical conditions, and initial ultrasonographic findings were collected. Linear and logistic regression analyses were performed to determine the prognostic factors associated with better clinical outcomes. RESULTS: Fifty-three patients (54 shoulders) were included. Linear regression analysis showed that coracohumeral ligament thickness of less than 3 mm, use of analgesics before hydrodilatation, and female sex were associated with good improvement in the Shoulder Pain and Disability Index score. Multivariate logistic regression analysis showed that coracohumeral ligament thickness of less than 3 mm on ultrasound was associated with a strong tendency (P = 0.054) of reaching the minimal detectable change. In addition, capsule rupture did not play a role in determining the clinical efficacy of hydrodilatation. CONCLUSIONS: In patients with primary adhesive capsulitis, coracohumeral ligament thickness of less than 3 mm is correlated with greater short-term improvement in the Shoulder Pain and Disability Index score after ultrasound-guided hydrodilatation with steroid injection is performed.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the feasibility of using subdural strip electrodes, placed just rostral to the surgical field, to record sensory evoked potentials (SEPs) from the lumbosacral sensory nerves and define the most inferior functional portion of the conus medullaris during detethering surgery for spinal dysraphism and/or tethered cord syndrome (TCS). METHODS: Six patients, 2 boys and 4 girls, aged 0.5 to 16 years, were enrolled in this study. One patient had lipomyelomeningocele-related, 4 had myelomeningocele-related, and 1 had diastematomyelia and lipomyelomeningocele-related TCS. In addition to the routine preparations that are needed for performing functional mapping and monitoring during surgery for spinal dysraphism and TCS, the patients had a 1 × 4 strip of electrodes placed rostral to the surgical field, where it was secured by a surgeon after opening the dura. With the patient under total intravenous anesthesia, the sensory nerves and conus medullaris were stimulated with a concentric bipolar electrode over the surgical field while SEPs were recorded with the strip electrodes to identify any possible sensory roots with remaining function and the most inferior functional portion of the conus medullaris. RESULTS: The SEP amplitudes that were recorded with the subdural strip electrodes ranged from 4 to 400 µV, and the responses to sensory nerve stimulation were frequently much larger than were those to conus stimulation. Use of the SEP recordings for sensory mapping along with the routine mapping and monitoring techniques allowed detethering to be completed such that none of the patients sustained any new functional deficit after surgery. CONCLUSIONS: Recording SEPs from the functional sensory nerves and conus medullaris through subdural strip electrodes proved to be a feasible and valuable tool during detethering surgery in young patients. This approach may help surgeons achieve maximal detethering while preserving important sensory functions, consequently retaining the patient's quality of life.

ABSTRACT

BACKGROUND: Congenital or early-onset brain structural lesions often cause contralateral hemiparesis, cognitive deficits, developmental delays, and seizures. Seizure is the most debilitating condition, as it greatly impairs quality of life in both the affected individuals and their caregivers and prevents them from active social participation. CASE DESCRIPTION: A 34-year-old man with hemiparesis and early-onset seizures since childhood owing to a congenital brain lesion developed intractable seizures in the last 2 years and was subsequently admitted for resective epileptic surgery. During the operation, we employed an innovative intraoperative neurophysiologic monitoring technique. In contrast to routine application for transcranial stimulation, we recorded compound muscle action potentials over the bilateral limb muscles simultaneously, instead of over the contralateral muscles only, to determine the patterns of the corticospinal projections. Transcranial stimulation over the bilateral hemispheres was applied before craniotomy, and direct cortical stimulation over the lesioned hemisphere was applied after craniotomy. By integrating both approaches, we could first identify the pattern of corticospinal projections before craniotomy and then accurately define the noneloquent area, which guided the resection to successfully accomplish the surgical goal. CONCLUSIONS: This technique is simple because no patient participation is required. We believe that it has the potential to replace conventional preoperative functional magnetic resonance imaging and transcranial magnetic stimulation in resective epilepsy surgery, particularly for young patients. Not only can it improve the safety of surgical procedures, but also it can help predict functional outcome.

ABSTRACT

The precise placement of recording electrodes at the relevant myotome is mandatory while performing pedicle screw stimulation (PSS) during spine surgery; however, their placement at trunk muscles is challenging. This study aimed to determine whether ultrasound guidance is useful for trunk muscle localization for PSS during spine surgery. A retrospective clinical study was conducted from a prospective database. Eighty-four patients eligible for spine surgery were recruited. Ultrasound was used to localize the intercostal, rectus abdominis, and internal oblique and psoas muscles if pedicle screw placement was performed at T3 to L1. After the operation, patients were examined for any new neurological deficits related to this procedure, and computed tomography was performed to check screw position if indicated. Four to 22 pedicle screws were used for spinal fixation. The threshold of stimulus to obtain a compound muscle action potential ranged from 1.29 to >20mA during PSS. Six of our patients sustained new postoperative deficits, and only one case was related directly to pedicel screw misplacement. Loss of motor evoked potential (MEP) over both the lower limbs was noted during pedicle screw placement, and the stimulus threshold during PSS were 1.29mA at the left T9 and 3.8mA at the right T5 level. MEP remained absent at the end of surgery despite removal of those two screws. The patient woke with significant weakness in both lower limbs (muscle power 0/0) and voiding difficulty. Fortunately, he regained walking ability 4.5months later after intensive rehabilitation therapy.

ABSTRACT

Acute sensory neuronopathy (SNN) is a rapidly developing peripheral nervous system disease that primarily affects sensory neurons in the dorsal root ganglion or trigeminal ganglion, leading to the impairment of sensory axons. SNN is notably uncommon in childhood; only three cases of childhood or adolescent SNN have been reported to date. Moreover, SSN has never been reported in association with enterovirus infection. Here, we report the case of a 3-year-old girl who was initially diagnosed with enterovirus infection based on the presentation of fevers, rashes on all extremities, and ulceration over the posterior pharynx. Nine days later, she presented with ataxic and wide-based gait and dysmetria affecting the extremities, with an absence of sensory nerve action potentials in the upper and lower limbs. The patient was diagnosed with acute SNN based on the criteria developed by Camdessanché et al in 2009. To our knowledge, this is the youngest case of SNN reported to date. In addition, this case reveals that enterovirus infection can be associated with acute SNN in children in rare cases. Accurate diagnosis relies on clinical suspicion, comprehensive knowledge of the patient's history, and careful characterization of abnormal findings in electrodiagnostic studies.

ABSTRACT

A 38-year-old man was healthy before presenting to our clinic with pain and marked weakness in the right upper extremity. He stated that the symptoms developed the day after he accidentally fell asleep while playing with his Smartphone half-lying on his back with two thick pillows supporting his upper back. Physical examination revealed significant increase in deep tendon reflexes in the lower extremities and clonus. Hoffman's sign was positive in the left upper extremity. Magnetic resonance image showed high signal change on T2-weighted images of the left spinal cord at the C4-5 level, which was indicative of compression myelopathy.
