PURPOSE: To compare the outcomes of distal neurotomy (DN) versus proximal neurotomy (PN) for the surgical management of painful neuromas in amputees and non-amputees, whether used in passive or active treatment. METHODS: A retrospective study was conducted on patients who underwent surgery for painful traumatic neuromas between 2019 and 2022. DN with neuroma excision was performed at the level of the injury or amputation. PN was performed using a separate proximal approach without neuroma excision...

Leprosy ulcer is a chronic and recurrent disease resulting from nerve injury. While existing treatments partially facilitate ulcer healing, they exhibit limited ability to address localized nerve repair, leading to a risk of recurrence. Moreover, there is a dearth of animal models to evaluate the preclinical efficacy and safety of novel therapeutic approaches. Over the years, adipose-derived mesenchymal stem cells have been extensively employed in regenerative medicine as an optimal cell therapy source for fostering skin ulcer healing...

SETTING: Department of Ophthalmology, Shaare Zedek Medical Center, Jerusalem, Israel.Design: retrospective cohort study. METHODS: Consecutive patients scheduled for cataract surgery were enrolled from February 2022 to August 2022...

BACKGROUND AND OBJECTIVE: Balance and walking capacity are often impaired in people with motor incomplete spinal cord injury (iSCI), frequently resulting in reduced functional ambulation and participation. This study aimed to assess the efficacy of walking adaptability training compared to similarly dosed conventional locomotor and strength training for improving walking capacity, functional ambulation, balance confidence, and participation in ambulatory people with iSCI. METHODS: We conducted a 2-center, parallel-group, pragmatic randomized controlled trial...

AIMS: To investigate whether higher serum CCL11/Eotaxin-1, a biomarker for aging and neurodegenerative and neuroinflammatory disorders, is associated with diabetic sensorimotor polyneuropathy (DSPN), peripheral nerve dysfunction, and cardiac autonomic neuropathy in people with type 2 diabetes. METHODS: This cross-sectional study included 106 patients with type 2 diabetes and 40 healthy controls, matched for the age and sex distribution of the diabetes group as a whole...

BACKGROUND: Nerve blocks are widely used in various surgeries to alleviate postoperative pain and promote recovery. However, the impact of nerve block on delirium remains contentious. This study aims to systematically evaluate the influence of Thoracic Paravertebral Nerve Block (TPVB) on the incidence of delirium in patients post Video-Assisted Thoracoscopic Surgery (VATS). METHODS: We conducted a systematic search of PubMed, Embase, Web of Science, Cochrane Library, and Scopus databases in June 2023...

OBJECTIVE: The aim of this study was to compare the clinical outcomes of spinal cord stimulation (SCS) and dorsal root ganglion stimulation (DRG-S) in the treatment of painful diabetic peripheral neuropathy (PDPN). METHODS: In this prospective cohort study, 55 patients received dorsal column spinal cord stimulation (SCS group) and 51 patients received dorsal root spinal cord stimulation (DRG-S group). The primary outcome was a Numerical Rating Scale (NRS) remission rate of ≥50%, and secondary outcomes included the effects of SCS and DRG-S on quality of life scores (EQ-5D-3L), nerve conduction velocity, and HbA1c, respectively...

Impaired diaphragm activation contributes to morbidity and mortality in many neurodegenerative diseases and neurologic injuries. We conducted experiments to determine if expression of an excitatory DREADD (designer receptors exclusively activation by designer drugs) in the mid-cervical spinal cord would enable respiratory-related activation of phrenic motoneurons to increase diaphragm activation. Wild type (C57/bl6) and ChAT-Cre mice received bilateral intraspinal (C4) injections of an adeno-associated virus (AAV) encoding the hM3D(Gq) excitatory DREADD...

BACKGROUND: Oesophagogastroduodenoscopy (OGDS) is the most common diagnostic procedure for upper gastrointestinal diseases. It often causes discomfort and anxiety, which are only mitigated by systemic sedation. However, sedation poses additional risks of adverse cardiopulmonary events, increased medical costs, and prolonged recovery. Transcutaneous electrical nerve stimulation of acupuncture points (Acu-TENS) is a non-invasive and innovative approach that induces analgesic effect during endoscopy...

INTRODUCTION: Conus medullaris infarction (CMI) is a rare vascular phenomenon that has been scarcely reported in the literature. While previous studies have described the clinical and radiological features of CMI, little attention has been paid to its associated neurophysiological findings. METHODS: We present a case of idiopathic CMI and its neurophysiological findings, then present our findings from a systematic review of other reports of CMI with neurophysiological features found via PubMed search...

Many ultrasound-guided procedures are available for administering analgesia via peripheral nerve blockade. This systematic review aims to compare different ultrasound-guided procedures to determine which procedure is better suited for pediatric abdominal surgeries. The objective is to understand the efficacy of ultrasound-guided procedures for postoperative pain management in children undergoing abdominal surgeries and to identify which procedure takes less time and is better suited for a particular surgery...

INTRODUCTION: Abdominal wall blocks, in conjunction with multimodal analgesia, have demonstrated efficacy in providing post-operative analgesia, reducing opioid requirements in patients undergoing inguinal hernia repair. The inguinal region is primarily innervated by the ilioinguinal nerve (IIN) and iliohypogastric nerve (IIH). Posterior transverse abdominis plane block (pTAP) and fascia transversalis plane block (TFP) have been observed to reliably block IIN and IIH. We hypothesized that posterior TAP block (pTAP) owing to its potential paravertebral spread will provide better post-operative analgesia than TFP block in patients undergoing unilateral open inguinal hernia repair...

INTRODUCTION: There is a sizable niche for a minimally invasive analgesic technique that could facilitate ambulatory video-assisted thoracoscopic surgery (VATS). Our study aimed to determine the analgesic potential of a single-shot erector spinae plane (ESP) block for VATS. The primary objective was the total hydromorphone consumption with patient-controlled analgesia (PCA) 24 h after surgery. METHODS: We conducted a randomized, controlled, double-blind study with patients scheduled for VATS in two major university-affiliated hospital centres...

Neurotoxic organophosphorus compounds can induce a type of delayed neuropathy in humans and sensitive animals, known as organophosphorus-induced delayed neuropathy (OPIDN). OPIDN is characterized by axonal degeneration akin to Wallerian-like degeneration, which is thought to be caused by increased intra-axonal Ca2+ concentrations. This study was designed to investigate that deregulated cytosolic Ca2+ may function downstream of mitodysfunction in activating Wallerian-like degeneration and necroptosis in OPIDN...

In the realm of long document classification (LDC), previous research has predominantly focused on modeling unimodal texts, overlooking the potential of multi-modal documents incorporating images. To address this gap, we introduce an innovative approach for multi-modal long document classification based on the Hierarchical Prompt and Multi-modal Transformer (HPMT). The proposed HPMT method facilitates multi-modal interactions at both the section and sentence levels, enabling a comprehensive capture of hierarchical structural features and complex multi-modal associations of long documents...

BACKGROUND: Late-onset Pompe disease (LOPD) patients may still need ventilation support at some point of their disease course, despite regular recombinant human alglucosidase alfa treatment. This suggest that other pathophysiological mechanisms than muscle fibre lesion can contribute to the respiratory failure process. We investigate through neurophysiology whether spinal phrenic motor neuron dysfunction could contribute to diaphragm weakness in LOPD patients. MATERIAL AND METHODS: A group of symptomatic LOPD patients were prospectively studied in our centre from January 2022 to April 2023...

BACKGROUND: Cranial autonomic symptoms (CASs) include lacrimation, conjunctival injection, rhinorrhea, nasal congestion, facial flushing or sweating, ptosis, and myosis. These symptoms may be associated with trigeminal autonomic cephalalgias (TACs) and migraine. OBJECTIVES: The aim of the study was to assess whether CASs are also reported by patients with frequent episodic tension-type headache (eTTH). MATERIAL AND METHODS: A cross-sectional online survey of a large Polish population was conducted between August 2021 and June 2022...

Aminoacyl-tRNA synthetases (ARSs) aminoacylate tRNA molecules with their cognate amino acid, enabling information transmission and providing substrates for protein biosynthesis. They also take part in nontranslational functions, mediated by the presence of other proteins domains. Mutations in ARS genes have been described as responsive to numerous factors, including neurological, autoimmune, and oncological. Variants of the ARS genes, both in heterozygosity and homozygosity, have been reported to be responsible for different pathological pictures in humankind...
