Description of WALANT technique in open bone and ligament wrist surgery.

The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist. WALANT surgery offers many known benefits, such as enhanced patient safety and comfort, simplified perioperative process and avoidance of anesthesia-related risks, and also allows the surgeon to perform intraoperative testing of the repaired structures. Thus, the surgeon can tailor the rehabilitation program and shorten recovery time. We describe detailed guidelines for performing WALANT procedures safely and effectively, making it a favorable option for complex surgeries in the wrist.

Effects of Whey Protein, Leucine, and Vitamin D Supplementation in Patients with Sarcopenia: A Systematic Review and Meta-Analysis.

(1) Background: In this study, a meta-analysis was performed to investigate the effects of whey protein, leucine, and vitamin D in sarcopenia; (2) Methods: We searched PubMed, Cochrane Library, Embase, and Scopus databases and retrieved studies published until 5 December 2022. Randomized controlled trials were included to evaluate muscle mass, strength, and function, after using whey protein, leucine, and vitamin D supplementation in patients with sarcopenia; (3) Results: A total of three studies including 637 patients reported the effectiveness of using whey protein, leucine, and vitamin D supplementation in patients with sarcopenia. Without considering whether or not a physical exercise program was combined with nutritional supplementation, no significant differences in grip strength or short physical performance battery (SPPB) scores between the experimental and control groups were noted. However, appendicular muscle mass significantly improved in the experimental group compared to the control group. The results were analyzed according to the presence or absence of a concomitant physical exercise program. With the use of a concomitant physical exercise program, handgrip strength and SPPB scores in the experimental group significantly improved when compared to the control group. In contrast, when physical exercise was not combined, there was no significant improvement in the handgrip strength and SPPB scores of patients with sarcopenia. In addition, the appendicular muscle mass significantly increased regardless of the presence of a concomitant physical exercise program; (4) Conclusions: Whey protein, leucine, and vitamin D supplementation can increase appendicular muscle mass in patients with sarcopenia. In addition, combining a physical exercise program with whey protein, leucine, and vitamin D supplementation can improve muscle strength and function.

Assessment of information on YouTube on the effect of acupuncture in patients with COVID-19: A cross-sectional study.

Medical-related information rapidly spreads throughout the internet. However, these types of information often contain inaccurate information, which can lead to harmful misconceptions. In this study, we evaluated the reliability, quality, and accuracy of videos uploaded on YouTube that harbor claims on the effects of acupuncture on COVID-19 treatment. This is a cross-sectional study. Videos uploaded on YouTube up to February 17, 2022, were searched, and the keywords used were as follows: "acupuncture," "coronavirus," "COVID 19," "COVID-19," "Corona," "COVID," and "SARSCoV2." The top 50 videos in English were viewed and evaluated. The reliability of the videos was evaluated using the modified DISCERN scale, the content-quality was evaluated using the Global Quality Scale. The accuracy of the information in each video was evaluated as well. Of the 50 videos, only 8% were found to be reliable and 64% were of poor quality. Additionally, 98% of the videos were misleading. The mean modified DISCERN scores was 1.72 and the mean Global Quality Scale score was 2.06. Despite the videos being made by experts, their reliability, content-quality, and accuracy were found to be low. The spread of inaccurate information may result in the use of inappropriate and potentially harmful treatment methods for patients. Videos that contain medical information should be produced based on verified scientific evidence.

The effect of neurologic music therapy in patients with cerebral palsy: A systematic narrative review.

Background: Cerebral palsy (CP) is one of the most common causes of disability in children. It is characterized by impairment in motor function and coordination and difficulties in performing daily life activities. Previous research supports that neurologic music therapy (NMT) was effective in improving motor function, cognition, and emotional wellbeing in patients with various neurologic disorders. However, the benefit of NMT in patients with CP have not yet been thoroughly investigated. The aim of this review was to investigate the potential effect of NMT motor rehabilitation techniques for patients. Materials and methods: We searched articles published up to May 24, 2022 in PubMed, Embase, Scopus, Cochrane library, Web of science, and Ovid MEDLINEdatabases. We included studies that investigated the effect of NMT in patients with CP. Results: After search, 4,117 articles were identified using the search terms. After reading the titles and abstracts, 4,089 articles that did not meet our inclusion criteria were excluded. The remaining 28 articles which were assessed for eligibility. Finally, 15 studies were included in this systematic review. Among 15 studies that investigated the effect of NMT on patients with CP, 7 studies were on rhythmic auditory stimulation (RAS), 6 studies were on therapeutic instrumental music performance (TIMP), and 2 studies were on patterned sensory enhancement (PSE). Conclusions: Various techniques of NMT brings beneficial effects for gross and fine motor improvements in patients with CP. NMT techniques, such as RAS, TIMP, and PSE, may be a potential alternative rehabilitation strategy to enhance gross and fine motor skills for patients with CP.

Ultrasound-guided 5-in-1 trigger point injection for treating tension-type headache: A case report.

RATIONALE: Tension-type headache (TTH) is the most common type of primary headache, and trigger point injection (TPI) is frequently used for controlling pain originating from TTHs. In the current report, we introduce a TPI technique involving 4 neck muscles (upper trapezius, splenius capitis, semispinalis capitis, and inferior oblique capitis) and a greater occipital nerve (GON) block within the same sonographic view for the treatment of TTHs. PATIENT CONCERNS: A 44-year-old woman complained with pressing and tightening, nonpulsating, recurrent headaches, mainly in the bilateral occipital area, lasting for approximately 6 months (numeric rating scale: 5). The patient had no nausea, vomiting, photophobia, or phonophobia. DIAGNOSES: The patient was diagnosed as having a TTH. INTERVENTIONS: Under ultrasound (US) guidance, a mixed solution of 2 mL of 2% lidocaine and 5 mL of normal saline was injected layer-by-layer into the 4 target muscles of the neck (upper trapezius, splenius capitis, semispinalis capitis, and inferior oblique capitis) and near the right GON within the same sonographic view bilaterally. OUTCOMES: Two- and 4-week follow-ups after administration of the injections revealed no headache. Our US-guided 5-in-1 TPI technique is viable for treating patients with TTH. LESSONS: We believe that it can aid in reducing the procedure time and associated pain.

YouTube as a source of information regarding the effect of vitamin C on coronavirus disease.

OBJECTIVES: With the expansion of the internet, social media platforms have become a major source of medical information. However, medical information on online multimedia platforms is often inaccurate. In the current study, we evaluated the reliability, quality, and accuracy of the most viewed YouTube videos featuring the effects of vitamin C on COVID-19. METHODS: A search was conducted on YouTube on January 13, 2022, using the keywords ("ascorbic acid" OR "vitamin C" OR "sodium ascorbate" OR "L-ascorbic") AND ("coronavirus" OR "COVID 19" OR "COVID-19" OR "Corona" OR "COVID" OR "SARSCoV2"). We assessed the 50 most-viewed videos using a modified DISCERN scale (mDISCERN) and Global Quality Scale (GQS). Additionally, the accuracy of the information in each video was evaluated. RESULTS: Out of the 50 most-viewed videos featuring the effect of vitamin C on COVID-19, 54% were not reliable. Furthermore, 62% presented poor quality, and 74% were misleading or neither accurate nor misleading. The average mDISCERN and GQS scores of the 50 included videos were 2.2 ± 1.4 (≥ 3: highly reliable) and 2.2 ± 1.1 (2: generally poor), respectively. Although the videos were made by medical doctors, their reliability, quality, and accuracy were not significantly different from those displayed in other sources, including fitness channels, television or internet-based news or programs, consumers, company channels, product advertisements, or prepared by nurses. CONCLUSIONS: The reliability, quality, and accuracy of the 50 most-viewed videos on the effect of vitamin C on COVID-19 were not high. Video creators, especially medical doctors, should make an effort so that the videos present reliable content with high-quality and correct information is disseminated to people.

Ultrasound-guided 3-in-1 trigger point injection for treating myofascial pain syndrome in muscles of the lateral scapular area: a case report.

BACKGROUND: Myofascial pain syndrome (MPS) is a common cause of musculoskeletal pain. MPS in the muscles of the lateral scapula frequently develops due to poor sitting posture (rounded shoulders and cervical kyphosis) in the office as well as long working hours. Herein, we introduce the use of the trigger point injection (TPI) technique in three muscles (i.e., the deltoid, infraspinatus, and teres major muscles) with the same sonographic view for the purpose of treating MPS in the lateral scapular area. CASE DESCRIPTION: A 48-year-old woman presented to our hospital complaining of dull pain in the right lateral scapular area that had persisted for 4 months. The numeric rating scale (NRS) pain score was 5. After confirming taut bands and tenderness in the muscles of the right lateral scapular area, we diagnosed the patient with MPS within the deltoid, infraspinatus, and teres major muscles. Under ultrasound (US) guidance, a mixed solution of 1 mL of 2% lidocaine and 2 mL of normal saline was injected layer by layer into the three muscles within the same sonographic view. At the 1-month follow-up (F/U) visit, the patient reported only slight initial pain (NRS score, 1). CONCLUSIONS: Thus, we recommend our US-guided 3-in-1 technique for performing TPI to treat MPS in the muscles of the lateral scapular area.

The effectiveness of high-dose intravenous vitamin C for patients with coronavirus disease 2019: A systematic review and meta-analysis.

OBJECTIVES: Vitamin C has anti-inflammatory effects. This review aimed to investigate the therapeutic effect of high-dose intravenous vitamin C (HDIVC) in patients with coronavirus disease 2019 (COVID-19). METHODS: The following key phrases were searched for article inclusion: "Vitamin C OR ascorbic acid" AND "COVID-19 OR coronavirus disease 2019 OR severe acute respiratory syndrome coronavirus 2 OR SARS-CoV-2″. Articles that utilized HDIVC for the management of patients with COVID-19 were included, whereas review articles and case reports were excluded from this review. Moreover, we performed a meta-analysis to evaluate whether HDIVC can reduce the length of hospital stay and in-hospital mortality rate of patients with severe COVID-19. RESULTS: In total, eight articles were included in this review, and five studies were included in the meta-analysis. The length of hospital stay was not significantly different between the HDIVC and control groups. Also, although our meta-analysis showed a tendency for HDIVC to reduce the in-hospital mortality rate in patients with severe COVID-19, the in-hospital mortality rate was not significantly different between patients treated with HDIVC and those who did not receive HDIVC. CONCLUSIONS: Evidence supporting the therapeutic use of HDICV in COVID-19 patients is lacking. Further studies are required for drawing a clear conclusion on this topic.

Effect of dietary vitamins C and E on the risk of Parkinson's disease: A meta-analysis.

BACKGROUND & AIMS: A neuroprotective effect of dietary vitamins C and E on Parkinson's disease (PD) has been suggested, however, several human studies have reported controversial results. Therefore, we conducted a meta-analysis on the effect of vitamins C and E on the risk of Parkinson's disease. METHODS: A comprehensive literature search was conducted using the PubMed, EMBASE, Cochrane Library, and SCOPUS databases for studies published up to January 23, 2021. We included studies that reported (1) intake of vitamins C and E using validated methods; (2) assessment of odds ratio (OR), relative risk (RR), or hazard ratio (HR); and (3) patients with PD identified by a neurologist, hospital records, or death certificates. The Comprehensive Meta-Analysis Software 2 program was used for statistical analyses of the pooled data. RESULTS: A total of 12 studies (four prospective cohort and eight case-control studies) were included in our meta-analysis. No significant risk reduction was observed in the high vitamin C intake group compared to low intake group. On the other hand, the high vitamin E intake group showed a significantly lower risk of development of PD than the low intake group (pooled OR = 0.799. 95% CI = 0.721 to 0.885). CONCLUSIONS: We conclude that vitamin E might have a protective effect against PD, while vitamin C does not seem to have such an effect. However, the exact mechanism of the transport and regulation of vitamin E in the CNS remains elusive, and further studies would be necessary in this field.

Spinal cord injury by direct damage during trigger point injection: a case report.

Trigger point injection (TPI) is commonly administered for myofascial pain syndrome management, but occasionally leads to complications, including bleeding, muscle hematoma, vasovagal syncope, skin infections, and pneumothorax. This report presents a case of TPI-induced iatrogenic spinal cord injury (SCI). A 59-year-old woman received TPI for myofascial pain on both thoracolumbar paraspinal muscles. She experienced an electric shock sensation throughout the lower extremities upon receiving blind TPI in the left thoracolumbar paraspinal muscle, and later complained of weakness (manual muscle test grade: 0-2) and neuropathic pain (numeric rating scale [NRS]: 7) in the lower left extremity. Thoracolumbar magnetic resonance imaging (MRI) 3 days after the TPI revealed a high-intensity T2 signal in the left T12 to L2 spinal cord segments, indicating the presence of edema or inflammation in this region. In concordance with the MRI findings, electrophysiological recordings performed 11 days after the TPI revealed no central motor conduction time response in the left leg. At 7 months post-onset, the patient had partially recovered motor function and neuropathic pain was reduced to NRS 4. Clinicians should be aware of the possibility of needle-induced SCI during paraspinal muscle TPI; imaging guidance may be helpful for accurate needle targeting during the procedure.

Mid-back pain due to a penetrating atherosclerotic aortic ulcer: do not miss the diagnosis-a case report.

In clinical practice, clinicians often meet patients suffering from mid-back pain. One of the possible causes of mid-back pain is penetrating atherosclerotic aortic ulcer (PAU), but the diagnosis is often delayed owing to its low incidence. Here, we report a patient with mid-back pain due to a PAU, who was diagnosed after receiving several procedures for reducing musculoskeletal pain. A 65-year-old man visited our pain clinic for mid-back pain [numeric rating scale (NRS): 7] experienced for 2 months. The pain was radiated to the lateral chest area and was aggravated when in the supine and standing positions. Trigger point injection, medial branch block, and pulsed radiofrequency were ineffective. The cardiac evaluation and abdominal computed tomography (CT) results showed no abnormalities. On CT aortography at 3 months after pain onset, intraluminal thrombus, multiple ruptured PAUs, and aneurysmal change of the descending thoracic aorta were found. Accordingly, PAU was diagnosed as the origin of the patient's pain. We administered nicardipine with a rate of 1.15 mcg/kg/min and esmolol with a rate of 100 mcg/kg/min for controlling the systolic blood pressure. In addition, an anticoagulant was administered orally. To alleviate the pain, we further administered intravenous opioid. Approximately 6 h after, the systolic blood pressure decreased to 100-120 mmHg, and the pain rating decreased to NRS 1. Two weeks after the discharge, the patient's pain rating was sustained at NRS 1. Clinicians should be aware of the fact that PAU can be a cause of mid-back or chest pain.

Conservative Treatments Frequently Used for Chronic Pain Patients in Clinical Practice: A Literature Review.

Chronic pain is a common patient complaint in clinical practice. It results in the deterioration of patients' quality of life and loss of productivity. Also, it often brings about psychiatric disorders such as depression and anxiety. Therefore, clinicians should manage chronic pain actively. Various conservative treatments, including pharmacological therapy, procedures, and exercise, are being used to control chronic pain. In this review article, I provide an overview of the commonly used treatments, including medication [anticonvulsants, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, antidepressants], procedures [injection of steroids and local anesthetics, pulsed radiofrequency (PRF), repetitive transcranial magnetic stimulation (rTMS), prolotherapy], and exercise. A brief overview of these treatments would allow clinicians to have an overall picture of the available tools for managing chronic pain in clinical practice at a glance.

Dilemmas Within the Korean Health Insurance System.

The health insurance system in Korea is well-established and provides benefits for the entire national population. In Korea, when patients are treated at a hospital, the hospital receives a partial payment for the treatment from the patient, and the remaining amount is provided by the health insurance service. The Health Insurance Review and Assessment Service (HIRA) assesses whether the treatment was appropriate. If HIRA deems the treatment appropriate, the doctor can receive payment from the health insurance service. However, this system has several drawbacks. In this study, we aimed to provide examples of the problems that can occur in relation to HIRA assessments in Korea through actual clinical cases.

Injury of the dentato-rubro-thalamic tract in a patient with intentional tremor after mild traumatic brain injury: a case report.

OBJECTIVES: We imaged the dentato-rubro-thalamic tract (DRTT) and cortico-ponto-cerebellar tract (CPCT) using diffusion tensor tractography (DTT) to evaluate the cortico-cerebellar-cortical circuit in a patient with tremor in both hands after mild TBI. We found bilateral DRTT injury in the DTT. METHOD: A 50-year-old male presented with action tremor in both hands 1 week after mild TBI. One month before the visit, the patient had a head injury from a fall on a bus. The patient lost consciousness for 1 min and experienced post-traumatic amnesia for approximately 5 min after the accident. His Glasgow Coma Scale score was 15. The action tremor presented with a frequency of 3 Hz in both hands. No specific lesion was observed with a conventional brain MRI. RESULTS: DTT, performed 1.5 months after TBI, showed that the right DRTT was not reconstructed and the left DRTT had thinned. However, CPCT integrity was well-preserved in both hemispheres. The tremor disappeared after oral treatment with 30 mg/day indenol. The patient's tremor would have been caused by disruption of the bilateral DRTT following mild TBI. CONCLUSION: DRTT and CPCT analysis using DTT would be useful for diagnosing abnormal movement problems, including tremor and ataxia, in patients following mild TBI.

The effect of balance training with Tetra-ataxiometric posturography on balance function in patients with parkinsonism.

BACKGROUND: Balance impairment is a major clinical concern in patients with parkinsonism. Balance training with tetra-ataxiometric posturography (Tetrax) is known to improve balance function through visual biofeedback effects. OBJECTIVE: In this study, we evaluated the effects of balance training with Tetrax in patients with parkinsonism. METHODS: Patients with parkinsonism (idiopathic Parkinson's disease, multiple systemic atrophy, and multiple systemic atrophy) who were able to stand with or without an assistive device were recruited for the study. Twenty patients with parkinsonism were randomly assigned to one of the following two groups: (1) the Tetrax group, in which patients received Tetrax biofeedback balance training for 30 min/day for 2 weeks (10 sessions); and (2) the control group, in which patients received conventional balance training for 30 min/day for 2 weeks (10 sessions). One day before and after training, we measured patients' balance parameters using the Berg balance scale (BBS) and fall index (FI). RESULTS: The BBS and FI scores of the Tetrax group showed significant improvements after compared to before training. However, the scores in the control group were not significantly changed after vs. before conventional balance training. CONCLUSIONS: For patients with parkinsonism, Tetrax biofeedback balance training had a positive effect on balance function.

Transcutaneous neuromuscular electrical stimulation applied to optimal points on the lower abdomen and lumbar paraspinal region changes gait parameters in patients with lumbar degenerative kyphosis.

BACKGROUND: Lumbar degenerative kyphosis (LDK) is characterized by sagittal imbalance resulting from degenerative loss of lumbar lordosis. The ability of transcutaneous neuromuscular electrical stimulation (NMES) to activate deep lumbar stabilizing muscles has been demonstrated. OBJECTIVE: The aim of this study was to evaluate the effects of transcutaneous NMES applied to optimal points on the lower abdomen and lumbar paraspinal region on gait problems in patients with lumbar degenerative kyphosis (LDK). METHODS: Twenty-one patients with lumbar degenerative kyphosis underwent three walking sessions in the following order; walking for 5 minutes without NMES, walking with NMES on the lumbar multifidus (LM) only, and walking with NMES on both LM and transverse abdominis (TrA)/obliquus internus (OI). Differences in gait parameters at the commencement and completion of each of the three sessions were evaluated by gait analysis. RESULTS: During the 5-minute walk with NMES applied to the LM or to the LM and TrA/OI, participants showed lesser increases in spine forward tilt, pelvic anterior tilt, and external foot progression angle, and a lesser decrease in hip internal rotation than when walking without NMES (P< 0.05). In addition, with NMES, patients showed less decrement in gait velocity and stride length at walk completion than patients walking without NMES (P< 0.05). However, in the comparison between walks with NMES applied to the LM and walks with NMES applied to the LM and TrA/OI, we could not find any significant difference in changes of gait parameters (p> 0.05). CONCLUSIONS: Transcutaneous NMES applied at optimal points on the lower abdomen and back could provide a means of treating gait problems caused by a stooped trunk in LDK patients.

Effects of high-frequency repetitive transcranial magnetic stimulation on reducing hemiplegic shoulder pain in patients with chronic stoke: a randomized controlled trial.

OBJECTIVE: To examine whether high-frequency (10 Hz) repetitive transcranial magnetic stimulation (rTMS), applied over the primary motor cortex of the affected hemisphere, could be used to manage hemiplegic shoulder pain (HSP). METHODS: Twenty-four chronic stroke patients with chronic HSP, randomly assigned into the rTMS group (10 sessions of high-frequency stimulation) or the sham group (sham stimulation), were performed. The Numeric Rating Scale (NRS) was used to evaluate the intensity of pain at pretreatment, and at 1 day, and 1, 2 and 4 weeks after treatment. Changes in upper-limb motor function were evaluated using the Motricity Index (MI-UL) and modified Brunnstrom Classification (MBC). RESULTS: When compared to pretreatment, the rTMS group showed a significant decrease in the NRS score at 1 day, and 1, 2 and 4 weeks after finishing rTMS sessions, with no significant change in the sham group. The NRS score after the rTMS sessions reduced by 30.1% at 1 day, 29.3% at 1 week, 28.0% at 2 weeks and 25.3% at 4 weeks. Passive shoulder range of motion, MI-UL, and MBC, however, did not significantly change in either group. CONCLUSIONS: High-frequency rTMS could be used as a safe, beneficial therapeutic tool to manage HSP. We think it can be used as an adjuvant therapeutic modality to enhance the therapeutic outcome of HSP.

Dorsal scapular nerve injury after trigger point injection into the rhomboid major muscle: A case report.

BACKGROUND AND OBJECTIVE: We report the case of a patient who presented with right dorsal scapular neuropathy after a trigger point injection into the right rhomboid major muscle. Through a nerve conduction study and electromyography, we demonstrated dorsal scapular nerve injury in this patient. CASE REPORT: A 38-year-old man complained that his right shoulder functioned less optimally during push-up exercises after a trigger point injection 4 weeks prior. Physical examination revealed mildly reduced right shoulder retractor muscle strength compared with the left side. We performed a nerve conduction velocity test and electromyography 5 weeks after the injection. The compound muscle action potential of the right dorsal scapular nerve showed low amplitude (left vs. right side: 5.2 vs. 1.6 mV) and delayed latency (left vs. right side: 4.9 vs. 6.8 ms). Positive sharp wave (1+) and mildly reduced recruitment were seen on electromyography of the rhomboid major muscle. The findings of the nerve conduction velocity test and electromyography indicated partial right dorsal scapular neuropathy. The nerve injury seemed to have been caused by the needle inserted during trigger point injection. CONCLUSION: Clinicians should pay attention to the occurrence of dorsal scapular nerve injury when performing trigger point injection into the rhomboid muscle.
