BACKGROUND
Traumatic injury to the long thoracic nerve causes paralysis of the serratus muscle, clinically expressed as winged scapula and functional impairment of the shoulder girdle. Treatment varies according to the severity of the injury, with a focus on early intervention for best results; however, the therapeutic approach remains a challenge at present.
CASE DESCRIPTION
We present the case of a 32-year-old male patient, athlete, right-handed, presented with bilateral paresis predominantly in the right arm, associated with paresthesia and changes in the coloring of the upper limbs. After being diagnosed with Thoracic Outlet Syndrome and undergoing surgery, vascular symptoms persisted with a significant loss of strength in the right shoulder. Winged scapula was observed and structural lesions were excluded on magnetic resonance imaging. Electromyographic studies confirmed the presumption of traumatic nerve involvement of the long thoracic nerve. Notwithstanding 6 months of physical therapy, there was no improvement, so a nerve transfer from the thoracodorsal nerve to the right long thoracic nerve was chosen. At 12 months, complete resolution of the winged scapula and functional recovery were observed. The patient also experienced a decrease in preoperative pain from 5/10 to 2/10 on the visual analog scale.
CONCLUSION
Nerve transfer from the thoracodorsal nerve to the long thoracic nerve is a safe and effective technique to treat winged scapula due to long thoracic nerve injury.

INTRODUCTION
Notalgia paresthetica (NP) is a chronic condition characterized by pruritus and other unpleasant dysesthetic sensations unilaterally on the subscapular back. Its specific underlying mechanisms are largely unknown, though hypothesized to be neuropathic. Determination of possible somatosensory contributors to the condition could pave the way for novel treatments.
OBJECTIVES
Given the potential involvement of non-pruritic mechanisms in NP, our objective was to broadly characterize the somatosensory function in NP-affected and unaffected skin using methods that have been standardized in pain-free controls and painful neuropathic disorders. We hypothesized that if NP is caused by neuropathic mechanisms not targeted directly to pruritoceptors in the skin, somatosensory abnormalities would not be itchspecific. Second, given the lack of symptoms on the contralateral side of the back, we hypothesized that this region would be normally sensitive.
METHODS
In this study, quantitative sensory testing (QST) was used to comprehensively assess the somatosensory function in 15 adult patients with NP. Standardized QST metrics were performed in the NP-affected region and compared with the contralateral asymptomatic skin and itch-free individuals using an age, gender, and site-matched reference data set.
RESULTS
There were no significant differences in sensitivity between symptomatic and asymptomatic skin, except for increased mechanical-evoked itch on the itchy side. However, reference data set comparisons revealed bilateral hyposensitivity to innocuous cold and noxious pinprick and higher temporal summation of pain in patients with NP. In addition, compared with reference data, patients with NP demonstrated decreased sensitivity to cold and pinprick, presence of paradoxical heat sensations, and increased wind-up of pain.
CONCLUSION
These results suggest a role for Aδ fiber pathways and central sensitization in NP-associated itch. More research is needed to determine whether sensory differences extend beyond the NP-affected dermatomal level and what might cause neuropathy specifically targeting Aδ fibers.

BACKGROUND
Burning mouth syndrome (BMS) is a chronic idiopathic facial pain with intraoral burning or dysesthesia. BMS patients regularly suffer from anxiety/depression, and the association of psychiatric symptoms with BMS has received considerable attention in recent years. The aims of this study were to investigate the potential interplay between psychiatric symptoms and BMS.
METHODS
Using 16S rRNA sequencing and liquid chromatography-mass spectrometry (LC/MS) to evaluate the oral microbiota and saliva metabolism of 40 BMS patients [including 29 BMS patients with depression or anxiety symptoms (DBMS)] and 40 age matched healthy control (HC).
RESULTS
The oral microbiota composition in BMS exhibited no significant differences from HC, although DBMS manifested decreased α-diversity relative to HC. Noteworthy was the discernible elevation in the abundance of proinflammatory microorganisms within the oral microbiome of individuals with DBMS. Parallel findings in LC/MS analyses revealed discernible disparities in metabolites between DBMS and HC groups. Principal differential metabolites were notably enriched in amino acid metabolism and lipid metabolism, exhibiting associations with infectious and immunological diseases. Furthermore, the integrated analysis underscores a definitive association between the oral microbiome and metabolism in DBMS.
CONCLUSIONS
This study suggests possible future modalities for better understanding the pathogenesis and personalized treatment plans of BMS.

BACKGROUND
Radial angiography, preferred for its safety and comfort in percutaneous coronary interventions, occasionally leads to paresthesia-a tingling or numbing sensation in the hand. This study aimed to investigate the presence of nerve damage in patients experiencing paresthesia post-radial angiography through electrophysiological examination.
METHODS
This prospective study involved 77 patients who developed hand paresthesia following radial angiography. Excluded were those with malignancy, pregnancy, pace-makers, or recent angiography. Nerve conduction studies were performed using the Neuropack MEB 9102K EMG device, assessing sensory and motor amplitudes, latencies, and velocities of median, ulnar, and radial nerves.
RESULTS
The study included 77 patients (23 females, 54 males; average age 58.39 ± 10.44 years). In 11 diabetic patients, polyneuropathy was detected. For the remaining 66 patients, electrophysiological evaluations showed no significant pathological findings. Comparative analysis of both upper extremities revealed no significant differences in nerve conduction parameters between the side where angiography was performed and the other side. Despite paresthesia complaints, no electrophysiological evidence of nerve damage was found, suggesting that symptoms might be due to local irritation rather than direct nerve injury. This aligns with the safety profile of radial angiography and underscores the importance of distinguishing between transient paresthesia and serious nerve complications.
CONCLUSION
Paresthesia post-radial angiography, while clinically notable, is not typically associated with nerve damage. This study is significant as it is the first in the literature to demonstrate that radial angiography does not cause nerve damage.

OBJECTIVE
Endoscopic surgery is a minimally invasive option for effectively addressing lumbar degenerative diseases. This study aimed to describe the specific technology of percutaneous transforaminal endoscopic lumbar foraminotomy (PTELF) as a therapeutic intervention for managing radicular leg pain (RLP) resulting from stable degenerative lumbar isthmic spondylolisthesis (DLIS) and to present the associated clinical results.
METHODS
From March 2022 and April 2023, 25 patients were diagnosed with single-level stable DLIS with RLP and underwent PTELF. Clinical assessments utilized the visual analog scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria. All endoscopic surgery videos were reviewed to interpret the pathology associated with DLIS.
RESULTS
The mean age of the cohort was 65.3 ± 11.0 years. The mean preoperative ODI score, VAS score for low back, and VAS score of the leg were 64.1 ± 8.2, 7.0 ± 0.7, and 7.3 ± 0.8, respectively. These scores significantly improved to 16.3 ± 10.4, 2.0 ± 0.6, and 1.7 ± 1.0 at the final follow-up, respectively (P<0.01). The modified MacNab criteria indicated "good" or "excellent" outcomes in 92.0% of cases. Analysis of 23 surgical videos revealed 15 patients with disc herniation, nine with lower vertebral endplate involvement, consistent presence of uneven bone spurs (at the proximal lamina stump and around the foramen), and accumulated scars. Two patients experienced postoperative dysesthesia, and one encountered a recurrence of RLP.
CONCLUSION
PTELF emerges as a potentially safe and effective procedure for alleviating RLP in patients with stable DLIS. However, additional evidence and extended follow-up periods are imperative to evaluate the feasibility and potential risks associated with PTELF.

Thoracic ossification of the ligamentum flavum (OLF) is known to result in spinal canal stenosis and myelopathy. It is typically treated through decompressive laminectomy and resection of the ossified ligament, which is known to improve neurological deficits. However, the recurrence of OLF post-surgery remains a relatively undocumented and complex issue. The present report describes the case of a 58-year-old male patient who had obesity (BMI 34), diabetes mellitus, and Basedow's disease. The patient presented with bilateral lower limb paresthesia and associated gait impairment, resulting in an urgent hospital admission. Imaging diagnostics identified extensive thoracic ossification of the posterior longitudinal ligament and OLF, both of which resulted in significant spinal cord compression. He underwent posterior decompression with instrumented fusion from T1 to T9 and additional laminectomy and OLF resection at T10/11. Despite an initial improvement in the postoperative period, the patient developed an epidural hematoma one week following surgery, causing significant paralysis of the lower limbs. This complication was promptly addressed with hematoma removal surgery. Six months after the initial procedure, his walking function improved significantly, but eight months after surgery, he experienced a sudden regression in motor functions due to the recurrence of OLF at T10/11, necessitating an additional posterior instrumented fusion surgery. Subsequent to the additional surgical procedure, the patient experienced an amelioration in paralysis, enabling him to ambulate with the aid of a cane. The recurrence of thoracic OLF after decompression surgery is a significant concern, especially in cases where decompression without instrumented fusion is performed. When determining the surgical procedure for thoracic OLF in cases with extensive ossification of the spinal ligaments, it is crucial to consider the degree of spontaneous fusion and mobility of the spinal segments, as demonstrated in the present case. The concentration of mechanical stress due to fusion at adjacent segments and intervertebral mobility at the thoracolumbar junction may increase the risk of OLF recurrence and should be carefully assessed preoperatively, even though posterior decompression surgery is typically considered a sufficient option for thoracic OLF.

Based on the presence of chronic pain and the potential use of common treatment agents in Notalgia Paresthetica (NP) and Fibromyalgia Syndrome (FMS) for improvement, we aimed to investigate the frequency of FMS symptoms in NP patients and its impact on quality of life. This study is a case control cohort study including 26 patients diagnosed with NP and a total of 26 controls matched for age and gender. The 2016 revised fibromyalgia diagnostic criteria by the American College of Rheumatology (ACR) were used to inquire about FMS diagnosis criteria in the study. According to the 2016 ACR revised FMS diagnostic criteria, the frequency of FMS was significantly higher in the patient group (n = 9, 34.6%) compared to the control group (n = 2, 7.7%) (p = 0.042). The Wide Pain Index (WPI) score in the control group was 2.00 (3.25), while in the patient group, it was 4.00 (8.00), with a statistically significant difference between them (p < 0.035). Furthermore, significant statistical differences were found between the two groups in terms of Symptom Severity Scale (SSS), Fibromyalgia Score (FS), and FIQ (p < 0.035, p < 0.001, p < 0.001, respectively). In NP patients with accompanying FMS, Dermatology Life Quality Index was significantly more affected compared to those without FMS (p = 0.025). In conclusion, we recommend that NP patients be questioned about FMS, which is characterized by generalized pain, as well as regional neuropathic symptoms. Treatment success can be enhanced by using common agents in the treatment choice for accompanying FMS.

Background Pelvic fractures caused by high-energy trauma, such as motor vehicle accidents or falls from a considerable height, commonly lead to sacral fractures. Approximately a quarter of sacral fractures are linked to neurological injury, and overlooking these fractures may result in neurological issues such as sexual dysfunction, hindered lower limb functionality, and urinary and rectal difficulties. The main goal of this study is to introduce our patient group who underwent either operative or nonoperative treatment for sacral fractures, with a follow-up period of one year, and assess their functional outcomes. Methodology This is a retrospective review of prospectively collected data from a consecutive series of patients at the Apex Trauma Centre, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow. A consecutive series of 24 patients (17-55 years old) with sacral fractures treated either operatively or nonoperatively from 2018 to 2023 was studied. A total of 20 patients were available for follow-up questionnaires, and 20 patients participated in a physical examination. Time to final follow-up averaged 27.19 months (range = 12-57 months). The personal data of each patient was collected, including gender, age, comorbidities, concomitant injuries, mechanism of injury, fracture pattern/classification, surgical or nonsurgical treatment, other surgeries, length of surgery, length of hospital stays, adverse events, complications, neurologic and/or motor deficits, bowel and bladder function, and mortality. At a minimum one-year follow-up, the Majeed score, Oswestry Disability Index (ODI) questionnaire, and Gibbon's classification were assessed. Results All fractures were healed. Five patients showed neurological weakness, with three patients having only paresthesia and two patients having lower limb weakness. The mean Majeed score was 75.4, representing a moderate clinical outcome. Final ODI scores averaged 10.6, representing mild disability among patients with sacrum fractures. Overall, 40% of sacrum fractures were associated with sexual dysfunction, with 30% of females and 50% of males reporting this issue. There was no significant difference (p > 0.05) between operated and conservatively managed sacrum fractures concerning ODI scores, neurological deficit, and sexual dysfunction. Conclusions Both male and female patients with traumatic sacrum fractures experienced a significant decrease in their quality of life and sexual function at least 12 months after their surgery. Sacrum fractures are associated with an increased prevalence of sexual dysfunction and bowel/bladder incontinence. Our study findings indicate that patients with sacrum fractures experience similar functional outcomes and incidences of sexual dysfunction irrespective of whether they are managed operatively or conservatively.

Spinal cord malignant melanotic schwannoma (MMNST) is a rare central nervous system tumor that originates from the spinal cord or spinal myelin sheath cells and can produce melanin. This type of tumor is usually highly aggressive and malignant, with a poor prognosis. The clinical manifestations of spinal cord MMNST are mainly pain, paresthesia, muscle weakness, muscle atrophy, etc., and symptoms of spinal cord compression, such as intestinal and bladder dysfunction, paraplegia, etc. Early detection of tumor lesions can facilitate tumor removal, improve patients' quality of life, and prolong patients' survival. In this case report, a 27-year-old young woman was diagnosed with MMNST of the cervical spinal cord due to weakness of her limbs in our hospital, and underwent surgical resection. The patient's limbs returned to normal after surgery. It is worth mentioning that the patient visited our hospital 7 months ago for "right upper limb pain for 3 days" and was diagnosed with a cervical spine space-occupying lesion at the same position this time, but the pathology report was "hemosiderosis".

KEY CLINICAL MESSAGE
We report an observation of a young patient presenting with severe type 1 cryoglobulinemic vasculitis revealing a monoclonal gammopathy of clinical significant. Treatment with Melphalan-Thalidomide Prednisone improved the symptoms. Early diagnosis would prevent serious tissue damage.
ABSTRACT
Monoclonal gammopathy encompass diverse clinical forms. Only the cancerous form, multiple myeloma (MM), is treated based on specific diagnostic criteria. A new clinical entity, monoclonal gammopathy of clinical significance (MGCS), warrants special attention due to its need for specific treatment. It involves patients with signs of potentially severe organ involvement that do not meet MM criteria. We present the case of a 34-year-old Malagasy woman with severe type I cryoglobulinemic vasculitis associated with noncancerous monoclonal gammopathy, showing a favorable outcome after treatment with Thalidomide. Symptoms included toe necrosis, a severe ulcer on the left calf evolving for 3 months, and stocking-like dysesthesias. Investigations revealed monoclonal gammopathy at 30.1 g/L, proteinuria at 1 g/24 h, medullary plasma cell at 6%, and circulating cryoglobulin of Ig kappa type. CRAB criteria (anemia, hypercalcemia, renal insufficiency, and osteolysis) were absent. Treatment with Thalidomide, combined with corticosteroids and local care for 4 months, resulted in ulcer healing, disappearance of dysesthesias, and persistent normalization of gammaglobulin. Our case underscores the importance of specific treatment for MGCS.
