Background Postpartum peripheral nerve injuries can impact recovery. Elastic stockings are recommended for thromboembolism prevention, although concerns about entrapment neuropathy exist. In this prospective observational study, we investigated the differential compressions caused by wearing elastic stockings before and after anesthesia, as well as changes in the diameters of the lower leg and ankle in parturient women undergoing spinal anesthesia for elective cesarean section (CS). Methods Eighteen pregnant women, classified by the American Society of Anesthesiologists as having physical status 2, underwent lower leg measurements taken before a CS. Elastic stockings were applied, and compression pressure was measured at pre-anesthesia, post-surgery, and six hours post-return to a hospital room. Fluid, blood loss, urine output, and neuropathy presence were recorded. For all parameters, changes at the three time points were compared for the primary analysis. For secondary analysis, participants were categorized as having intraoperative blood loss greater than (group P) or less than 1,000 g (group N), and factors were compared with pre-anesthesia and six hours post-return to a room. Data were analyzed and presented using a one-way analysis of variance with Bonferroni correction for multiple comparisons or unpaired two-tailed t-tests for pairwise comparison. Results None of the women had postoperative entrapment neuropathy. Six patients had >1,000 g of blood loss. Compression significantly increased from pre-anesthesia (left 13.6 ± 2.4, 95% CI: 12.18 to 14.52; right 13.4 ± 2.4, 95% CI: 12.41 to 14.69) to post-surgery (left, 17.4 ± 2.6, 95% CI: 15.68 to 18.12; right, 16.9 ± 2.6, 95% CI: 16.20 to 18.70) (p < 0.01). Compression pressure at post-surgery differed significantly between group P (left, 15.3 ± 1.3; right, 14.7 ± 1.8; 95% CI: -4.98 to -0.32) and group N (left, 18.1 ± 2.9; right, 17.8 ± 2.4; 95% CI: -5.38 to -0.26) (p < 0.05). The results are expressed as mean ± standard deviation, with P-values <0.05 indicating statistical significance. Conclusions In this study, no neuropathy occurred; however, over-compression risk with elastic stockings, especially when exceeding recommended pressure levels, was highlighted. Balancing thromboembolism prevention and over-compression risks is crucial for patients undergoing CSs with spinal anesthesia.

BACKGROUND
Intractable hiccups, persisting beyond 48 h, pose a clinical challenge, particularly in demyelinating diseases like Neuromyelitis Optica (NMO) and Multiple Sclerosis (MS). Understanding the complex neural pathways of the hiccup reflex and the impact of high-dose steroid therapy is crucial for managing this rare but distressing symptom. The hiccup reflex involves afferents from the vagus, phrenic, and sympathetic nerves, with the reflex center in the anterior horns at the C3 to 5 level and the medulla oblongata. The potential interplay between demyelination and corticosteroid therapy in triggering persistent hiccups requires exploration.
CASE REPORT
This case report details a 21-year-old male with undiagnosed demyelinating disorder, presenting persistent hiccups following high-dose steroid therapy for an acute disease flare. The patient's history included vertigo and progressive neurological symptoms, leading to an MS diagnosis with significant brain and spinal lesions. Persistent hiccups, initiated by steroid administration, were recurrent but responsive to metoclopramide after other measures failed.
DISCUSSION
The discussion centers on investigating the cause of hiccups in a patient with demyelination following steroid administration. Steroids' impact on neurological systems, including neurotransmitter function, and the potential disruption of neurological pathways due to demyelination may contribute to hiccups. Successful hiccup resolution with metoclopramide suggests a potential pharmacological approach for corticosteroid-induced hiccups in demyelinating diseases. This case emphasizes the need for further research into the intricate relationship between demyelination, steroid therapy, and hiccups to enhance management strategies for this uncommon yet impactful symptom.

Schwannoma is a nerve sheath tumour arising from differentiated Schwann cells, and melanocytic schwannoma (MS) is a rare variant where the Schwan cells produce melanin pigment. MS is typically associated with spinal nerve roots and there have been only ~20 reports of cutaneous or subcutaneous MS to-date in humans. In canines, there have only been two reports of MS, both associated with spinal root nerves. In this report, we describe a 7-year-old Weimaraner cross breed dog that presented with two pigmented lesions on the eyelids. The lesions were surgically removed and histological analysis revealed well-circumscribed, non-encapsulated, expansile, neoplasms that were displacing most of the dermis and adnexa. The first lesion was composed of spindloid cells arranged in short interlacing streams with large amounts of pale eosinophilic cytoplasm that sometimes contained fine melanin granules. In areas there were spindle cells arranged in verocay bodies which led to a diagnosis of MS. In contrast, the second lesion was composed of polygonal cells arranged in thick sheets with large amounts of pale eosinophilic cytoplasm that sometimes contained fine melanin granules. The diagnosis was melanocytoma (which is one of the macroscopic differential diagnoses for MS). Whilst melanocytoma is a commonly occurring cutaneous lesion in canines and surgical removal is considered curative, due to little being known about MS in dogs, the outcome remained guarded, as MS in humans has an unpredictable nature, and recurrence and metastasis have been reported.

INTRODUCTION
Thromboangiitis obliterans (TAO) or Buerger's disease (BD) is a small and medium-sized arteriovenous segmental occlusive inflammatory disease frequently occurring in men as compared to women. Although a common etiological agent is smoking or tobacco consumption, it has also been reported infrequently in non-smokers. Except for smoking other etiological agents, HLA, autoimmune diseases like systemic lupus erythematosus, and periodontitis have also been suggested. Minimally invasive pain and spine intervention (MIPSI) like stellate ganglion neurolysis with 8% phenol, 10 days apart in patients suffering from bilateral digital ischemia of both hands is a safe and effective treatment.
CASE REPORT
Fifty-five-year-old female with chief complaints of burning pain, swelling, and blackening of all five fingers of the right and four fingers of the left hands excluding the thumb for the past 3 months. On examination, pulse was almost absent at the wrist in both hands. There was no history of smoking. Under aseptic precautions, fluoroscopy and radiocontrast guidance stellate ganglion neurolysis with a 22G spinal needle, 2 ml of 8% phenol, 2 ml of 0.25% bupivacaine and 4 mg of dexamethasone were given at C7 vertebral level 10 days apart on both sides. After 3-4 months of stellate ganglion phenol chemical neurolysis, involved fingers were saved except the gangrenous part which was autoamputated itself in due course of time.
CONCLUSION
Bilateral interval (10 days apart) chemical neurolysis of stellate ganglion in Buerger's disease involving both hands is a safe and effective technique in terms of control of disease progression, pain, cardiac complications, and recurrent laryngeal nerve-related complications.

Adductor canal block is a widely used regional anesthesia technique for total knee arthroplasty that helps in reducing post-surgical pain and opioid use. Anatomically, the adductor canal extends from the apex of the femoral triangle proximally to the adductor hiatus distally and is roofed by the sartorius and vasto-adductor fascia. All these serve as a potential path for the spread of the local anesthetic when it is injected inside the adductor canal during the block. Subsartorial space is of unique interest as it lies between the sartorius and vasto-adductor fascia, carrying the subsartorial plexus that can provide additional analgesia to the knee when the adductor canal block injectate spreads into it. While the spread can be variable, ultrasound can be a useful tool to evaluate this spread. This is a case series of patients who underwent total knee arthroplasty under spinal anesthesia and adductor canal blocks. We present the findings of ultrasound evaluation of the injectate spread following adductor canal blocks and evaluation of their analgesia effects.

Desmoid tumours of the brachial plexus are rare locally infiltrative aggressive, monoclonal, fibroblastic proliferations characterized by a variable and often unpredictable clinical course. Only 21 patients have been reported in the literature. We add another one, and report function-preserving surgery in a 34-year-old man with a desmoid tumour of the brachial plexus. The patient presented with paraesthesia and gradually progressive distal muscle weakness in the left upper limb. Electrodiagnostic studies revealed preganglionic changes in segments C8-D1. Contrast-enhanced magnetic resonance imaging showed an enhancing mass with irregular margins in the left paravertebral region encasing the subclavian artery, pre- and post-ganglionic C6-D1 nerve roots and trunks of the brachial plexus. Using an anterior transclavicular approach the tumour was decompressed, which led to a major improvement in paraesthesia and partial motor recovery. He was doing well at 6 months of follow-up. Histopathological examination showed findings consistent with desmoid tumour. A tailored multidisciplinary surgical approach, with the aim to preserve function over radiological clearance, is an acceptable treatment strategy in preserving patient's quality of life for such infiltrating desmoid tumours encasing the brachial plexus. Following surgery, observation and close radiological surveillance offer an optimal strategy without jeopardizing the quality of life.

BACKGROUND
Blood always shows coagulation changes after spinal cord injury (SCI), and identifying these blood changes may be helpful for diagnosis and treatment of SCI. Nevertheless, studies to date on blood coagulation changes after SCI in humans are not comprehensive. Therefore, this study aims to identify blood coagulation diagnostic biomarkers and immune changes related to SCI and its severity levels.
METHODS
Human blood sequencing datasets were obtained from public databases. Differentially expressed coagulation-related genes were analyzed (DECRGs). Enrichment analysis and assessment of immune changes were conducted. Weighted gene co-expression network analysis, least absolute shrinkage and selection operator logistic regression were used to identify biomarkers. Validation for these biomarkers was performed. The correlation between biomarkers and immune cells was evaluated. Transcription factors, miRNA, lncRNA, and drugs that can regulate biomarkers were analyzed.
RESULTS
DECRGs associated with SCI and its different grades were identified, showing enrichment in altered coagulation and immune-related signaling pathways. ADAM9, CD55, and STAT4 were identified as coagulation diagnostic biomarkers for SCI. IRF4 and PABPC4 were identified as coagulation diagnostic biomarkers for American Spinal Injury Association Impairment Scale (AIS) A grade of SCI. GP9 was designated as a diagnostic biomarker for AIS D grade of SCI. Immune changes in blood of SCI and its different grades were observed. Correlation between diagnostic biomarkers and immune cells were identified. Transcription factors, miRNA, lncRNA, and drugs that can regulate diagnostic biomarker expression were discovered.
CONCLUSION
Therefore, detecting the expression of these putative diagnostic biomarkers and related immune changes may be helpful for predicting the severity of SCI. Uncovering potential regulatory mechanisms for biomarkers may be beneficial for further research.

PURPOSE
Prolonged mechanical ventilation (PMV) and reintubation are among the most serious postoperative adverse events associated with malignant cervical tumors. In this study, we aimed to clarify the incidence, characteristics, and risk factors for PMV and reintubation in target patients.
METHODS
This retrospective nested case-control study was performed between January 2014 and January 2020 at a large spinal tumor center in China. Univariate analysis was used to identify the possible risk factors associated with PMV and reintubation. Logistic regression analysis was performed to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) with covariates of a probability < 0.05 in univariate analysis.
RESULTS
From a cohort of 560 patients with primary malignant (n = 352) and metastatic (n = 208) cervical tumors, 27 patients required PMV and 20 patients underwent reintubation. The incidence rates of PMV and reintubation were 4.82% and 3.57%, respectively. Three variables (all p < 0.05) were independently associated with an increased risk of PMV: Karnofsky Performance Status < 50 compared to ≥ 80, operation duration ≥ 8 h compared to < 6 h, and C4 nerve root encased by the tumor. Longer operative duration and preoperative hypercapnia (all p < 0.05) were independent risk factors for postoperative reintubation, both of which led to longer length of stay (32.6 ± 30.8 vs. 10.7 ± 5.95 days, p < 0.001), with an in-hospital mortality of 17.0%.
CONCLUSION
Our results demonstrate the risk factors for PMV or reintubation after surgery for malignant cervical tumors. Adequate assessment, early detection, and prevention are necessary for this high-risk population.

BACKGROUND
The incidence of minimally invasive heart surgery via mini-thoracotomy (MT; right anterior thoracotomy) is on the rise, accompanied by an increase in post-MT intercostal nerve neuralgia and the risk of lung herniation through the incision site. While various methods have been proposed to address these issues, none have been commonly effective. In this case report, we attempted to simultaneously address these problems by performing intercostal cryoablation (IC) and mesh repair.
CASE PRESENTATION
A 43-year-old male was referred to our hospital for chronic post-thoracotomy neuralgia following heart surgery via MT, involving patch closure of an atrial septal defect and tricuspid annuloplasty. He presented with intercostal nerve neuralgia and lung herniation accompanied by severe pain. Despite medication and lidocaine injections, there was no relief. Consequently, he underwent surgical treatment with IC for chronic MT wound pain and simultaneously underwent mesh repair for a lung hernia. He was discharged from hospital free of complications. Subsequently, he no longer required further pain medication and experienced a favorable recovery.
CONCLUSION
Our findings suggest that concurrent IC and mesh repair can effectively relieve chronic post-MT intercostal nerve neuralgia and severe lung herniation pain in patients who underwent MT surgery, leading to a decrease in opioid medication usage.

Despite a 15% misplacement rate of screws in idiopathic scoliosis surgery, little is known about the relationship between pedicles and nerve structures in the entire thoracic curve. This study aimed to explore the spinal cord's proximity to the pedicle wall at each thoracic vertebra in the entire thoracic curve, while considering different anatomical changes. Spinal cord to medial pedicle distances were measured on magnetic resonance imaging in 73 patients who underwent posterior spinal fusion with pedicle screw instrumentation. Associations with different variables were examined. A total of 51 patients (69.9%) showed a distance within 2 mm at the apex vertebra on the concave side, more than 50% had a distance within 2 mm in the next thoracic vertebra level above and below, and more than 25% two levels above and below. Weak correlations were found between proximity of the spinal cord at the apex vertebra and vertebra's level and Cobb angle on the concave side (r = - 0.310, P = 0.008, r = 0.380, P = 0.001, respectively). These results emphasize the importance of thorough assessment when placing thoracic pedicle screws in idiopathic scoliosis patients. Further research is warranted to develop surgical strategies aimed at preventing potentially neurological complications resulting from screw misplacement.
