Multi-feature, Chinese-Western medicine-integrated prediction model for diabetic peripheral neuropathy based on machine learning and SHAP.

BACKGROUND: Clinical studies have shown that diabetic peripheral neuropathy (DPN) has been on the rise, with most patients presenting with severe and progressive symptoms. Currently, most of the available prediction models for DPN are derived from general clinical information and laboratory indicators. Several Traditional Chinese medicine (TCM) indicators have been utilised to construct prediction models. In this study, we established a novel machine learning-based multi-featured Chinese-Western medicine-integrated prediction model for DPN using clinical features of TCM. MATERIALS AND METHODS: The clinical data of 1581 patients with Type 2 diabetes mellitus (T2DM) treated at the Department of Endocrinology of the First Affiliated Hospital of Anhui University of Chinese Medicine were collected. The data (including general information, laboratory parameters and TCM features) of 1142 patients with T2DM were selected after data cleaning. After baseline description analysis of the variables, the data were divided into training and validation sets. Four prediction models were established and their performance was evaluated using validation sets. Meanwhile, the accuracy, precision, recall, F1 score and area under the curve (AUC) of ROC were calculated using ten-fold cross-validation to further assess the performance of the models. An explanatory analysis of the results of the DPN prediction model was carried out using the SHAP framework based on machine learning-based prediction models. RESULTS: Of the 1142 patients with T2DM, 681 had a comorbidity of DPN, while 461 did not. There was a significant difference between the two groups in terms of age, cause of disease, systolic pressure, HbA1c, ALT, RBC, Cr, BUN, red blood cells in the urine, glucose in the urine, and protein in the urine (p < 0.05). T2DM patients with a comorbidity of DPN exhibited diverse TCM symptoms, including limb numbness, limb pain, hypodynamia, thirst with desire for drinks, dry mouth and throat, blurred vision, gloomy complexion, and unsmooth pulse, with statistically significant differences (p < 0.05). Our results showed that the proposed multi-featured Chinese-Western medicine-integrated prediction model was superior to conventional models without characteristic TCM indicators. The model showed the best performance (accuracy = 0.8109, precision = 0.8029, recall = 0.9060, F1 score = 0.8511, and AUC = 0.9002). SHAP analysis revealed that the dominant risk factors that caused DPN were TCM symptoms (limb numbness, thirst with desire for drinks, blurred vision), age, cause of disease, and glycosylated haemoglobin. These risk factors were exerted positive effects on the DPN prediction models. CONCLUSIONS: A multi-feature, Chinese-Western medicine-integrated prediction model for DPN was established and validated. The model improves early-stage identification of high-risk groups for DPN in the diagnosis and treatment of T2DM, while also providing informative support for the intelligent management of chronic conditions such as diabetes.

Endoscopically-assisted extraction of broken roots or fragments within the mandibular canal: a retrospective case series study.

PURPOSE: To assess the impact of endoscope-assisted fractured roots or fragments extraction within the mandibular canal, along with quantitative sensory testing (QST) alterations in the inferior alveolar nerve (IAN). METHODS: Six patients with lower lip numbness following mandibular third molar extraction were selected. All patients had broken roots or fragments within the mandibular canal that were extracted under real-time endoscopic assistance. Follow-up assessments were conducted on postoperative days 1, 7, and 35, including a standardized QST of the lower lip skin. RESULTS: The average surgical duration was 32.5 min, with the IAN exposed in all cases. Two of the patient exhibited complete recovery of lower lip numbness, three experienced symptom improvement, and one patient remained unaffected 35 days after the surgery. Preoperative QST results showed that the mechanical detection and pain thresholds on the affected side were significantly higher than those on the healthy side, but improved significantly by postoperative day 7 in five patients, and returned to baseline in two patients on day 35. There were no significant differences in the remaining QST parameters. CONCLUSIONS: All endoscopic surgical procedures were successfully completed without any additional postoperative complications. There were no cases of deterioration of IAN injury, and lower lip numbness recovered in the majority of cases. Endoscopy allowed direct visualization and examination of the affected nerve, facilitating a comprehensive analysis of the IAN.

Predictive factors of the postoperative proptosis recovery in surgery of spheno-orbital meningiomas.

OBJECTIVE: This study aimed to identify factors affecting proptosis recovery in spheno-orbital meningioma (SOM) surgery and assess functional and oncological outcomes. METHODS: Data from 32 consecutive SOM surgery cases (2002-2021) were analyzed. Clinical, radiological, operative, and oncological parameters were examined. Proptosis was assessed using the exophthalmos index (EI) on MRI or CT scans. Statistical analyses were performed to identify predictive factors for proptosis recovery. RESULTS: Proptosis improved in 75% of patients post-surgery (EI decreased from 1.28 ± 0.16 to 1.20 ± 0.13, p = 0.048). Patients with stable or worsened EI had higher body mass index (28.5 ± 7.9 vs. 24.1 ± 4.7, p = 0.18), Simpson grade (IV 75% vs. 65%, p = 0.24), and middle sphenoid wing epicenter involvement (63% vs. 38%, p = 0.12), but no significant factors were associated with unfavorable exophthalmos outcomes. The improvement group had higher en plaque morphology, infratemporal fossa invasion, and radiation treatment for cavernous sinus residual tumor (88% vs. 75%, p = 0.25; 51% vs. 25%, p = 0.42; 41% vs. 25%, p = 0.42, respectively), but without statistical significance. Visual acuity remained stable in 78%, improved in 13%, and worsened in 9% during follow-up. Surgery had a positive impact on preoperative oculomotor nerve dysfunction in 3 of 4 patients (75%). Postoperative oculomotor nerve dysfunction was observed in 25%, of which 75% fully recovered. This occurrence was significantly associated with irradiation of an orbital tumor residue (p = 0.04). New postoperative trigeminal hypoesthesia was observed in 47%, of which 73% recovered. All SOMs were classified as WHO grade 1, and complementary treatments achieved oncological control, requiring gamma-knife radiosurgery in 53% and standard radiotherapy in 6%. CONCLUSIONS: Surgery effectively improves proptosis in SOM, though complete resolution is rare. The absence of predictive factors suggests multifactorial causes, including body mass index and tumor resection grade. Postoperative oculomotor nerve dysfunction and trigeminal hypoesthesia are common but often recover. Gamma-knife radiosurgery maintains long-term oncological control for evolving tumor residue.

[Application of microchannel technique in minimally invasive resection of cervical intraspinal tumors].

OBJECTIVE: To explore the application and key points of microchannel approaches in resection of cervical intraspinal tumors. METHODS: A retrospective analysis was performed on 51 cases of cervical spinal canal tumors from February 2017 to March 2020. Among them, 5 cases were located epidural space, 6 cases were located epidural and subdural space, and 40 cases were located under the subdural extramedullary space(6 cases were located on the ventral side of the spinal cord). The maximum diameter ranged from 0.5 to 3.0 cm. The clinical manifestations included neck, shoulder or upper limb pain 43 cases, sensory disturbance (numbness) in 22 cases, and limb weakness in 8 cases. The microchannel keyhole technique was used to expose the tumor, and the tumor was resected microscopically. RESULTS: In this study, 35 patients underwent hemilaminectomy, 12 patients underwent interlaminar fenestration, 2 patients underwent medial 1/4 facetectomy on the basis of hemilaminectomy or interlaminar fenestration. Two tumors were resected through anatomy space (no bone was resected). The degree of tumor resection included total resection in 50 cases and subtotal resection in 1 case. The type of the tumor included 36 schwannomas, 12 meningiomas, 2 enterogenic cysts and 1 dermoid cyst. There was no infection and cerebrospinal fluid leakage postoperatively. Limb numbness occurred in 7 patients. The average follow-up time was 15 months (3 to 36 months). No deformity such as cervical instability or kyphosis was found. The tumor had no recurrence. CONCLUSION: The cervical spinal canal is relatively wide, cervical tumors with no more than three segments can be fully exposed by means of microchannel technology. Besides intramedullary or malignant tumors, they can be microsurgically removed. Preservation of the skeletal muscle structure of cervical spine is beneficial to recover the anatomy and function of cervical spine. The electrophysiological monitoring helps to avoid spinal cord or nerve root injury.

Clinical study on treatment of cervical spondylotic radiculopathy (Qi stagnation and blood stasis syndrome) with Gao's nape needle and Shentong Zhuyu decoction.

BACKGROUND: Cervical spondylotic radiculopathy is currently one of the common orthopedic diseases, mainly characterized by neck pain, stiffness, limited mobility, and related symptoms of nerve root compression, which seriously troubles people's work and life. METHODS: Ninety cases of cervical spondylotic radiculopathy (Qi stagnation and blood stasis syndrome) were randomly divided into treatment group and control group, 45 cases in each group. The control group was treated with western medicine (nerve nutrition, pain relief, and circulation improvement drugs), and the treatment group was treated with Gao's nape needle combined with modified Shentong Zhuyu decoction on the basis of the control group. Before and after 2 weeks, TCM syndrome score, TCM curative effect, visual analogue scale score, numbness score, neck disability index score, related serum inflammatory factors (interleukin-10 [IL-10], interleukin-6 [IL-6], tumor necrosis factor-α [TNF-α]), related hemorheological indexes (plasma viscosity, high shear whole blood viscosity, low shear whole blood viscosity level) were used as evaluation indexes to evaluate the effect. RESULTS: After treatment, the total effective rate of the treatment group was 91.11%, which was better than that of the control group (78.78%), and the TCM syndrome scores of the 2 groups were decreased, the treatment group was better than that of the control group, and the differences were statistically significant (P < .05). After treatment, the visual analogue scale score, numbness score, and neck disability index score were decreased in both groups, and the decrease in the treatment group was more significant than that in the control group, and the differences were statistically significant (P < .05). After treatment, the related serum inflammatory factors (IL-10, IL-6, TNF-α) and related hemorheological indexes (plasma viscosity, high-shear whole blood viscosity, low-shear whole blood viscosity) were decreased in both groups, and the decrease in the treatment group was more significant than that in the control group, and the differences were statistically significant (P < .05). CONCLUSION: The treatment of cervical spondylotic radiculopathy (Qi stagnation and blood stasis syndrome) with Gao's nape needle and modified Shentong Zhuyu decoction can improve the curative effect of traditional Chinese medicine, improve the related discomfort symptoms (neck tenderness, adverse activity, numbness, etc), improve the neck function, reduce IL-10, IL-6, TNF-α, and other related serum inflammatory factors, and improve hemorheological indicators.

Acute, long-term or non-vincristine-induced peripheral neuropathy among non-Hodgkin lymphoma survivors: Symptoms, daily activities, functional status, and quality of life.

PURPOSE: This study aimed to explore the incidence and severity of vincristine-induced peripheral neuropathy (VIPN) in non-Hodgkin lymphoma (NHL) survivors (primary aim) and its impact on daily life by comparing common cancer symptoms, functional status, and quality of life (QoL) among survivors with acute, long-term, and non-VIPN (secondary aim). METHODS: This cross-sectional study examined 144 NHL survivors. Standardized questionnaires were used to assess common cancer symptoms, functional status, and QoL with the European Organization for the Research and Treatment of Cancer - Quality of Life Questionnaire (EORTC-QLQ-C30). VIPN (Chemotherapy-Induced Peripheral Neuropathy) status was classified using EORTC-QLQ-CIPN20. A self-designed interference scale was developed to determine the impact of the VIPN on daily activities. The Kruskal-Wallis test and Spearman rank correlation were used in this study. RESULTS: Among the survivors of acute and long-term VIPN, the highest incidences and most severe symptoms were found for hand numbness and foot cramps. A significant moderate correlation was found between disturbances in daily activities and acute or long-term VIPN, including gait changes, going up or down the stairs, and imbalance-related falls. Acute and long-term VIPN survivors showed worse symptoms (fatigue, insomnia, and constipation) and lower QoL than non-VIPN survivors did. In acute VIPN, social function was significantly affected, whereas in long-term VIPN, emotional and cognitive functions were affected. CONCLUSION: Numbness and cramps should be addressed in survivors of acute and long-term VIPN. Preventing falls is recommended for NHL survivors with VIPN, and psychological support is suggested for long-term VIPN survivors.

[Frameless trigeminal neuralgia radiosurgery with a dedicated linear accelerator: From equipment commissioning to initial clinical results]. / Radiochirurgie des névralgies trigéminales avec accélérateur linéaire dédié sans cadre invasif : de la mise en service de l'appareil aux premiers résultats cliniques.

PURPOSE: Radiosurgery for the treatment of trigeminal neuralgia delivers a very high dose in a single fraction, over a few millimeters, at a single isocenter placed along the nerve. We present here the different steps that have been performed to validate small beams by conical collimators, and report the clinical results of the first patients treated on Novalis Tx®, frameless. MATERIAL AND METHODS: First, the geometric accuracy of 4 and 6mm conical collimators was evaluated using Winston-Lutz tests; then dosimetric data acquisition was performed using high spatial resolution detectors (PTW 60019 microdiamond and a PTW 60017 E-diode). The corrective factors of the TRS 483 report were applied to calculate the collimator aperture factors. These dosimetric data were then compared with the data implemented in the iPlan® treatment planning system. Then end-to-end tests were performed to control the entire treatment process using an anthropomorphic phantom "STEEV". Between 2020 and 2022, 18 patients were treated for refractory trigeminal neuralgia on Novalis Tx®, frameless, with Exactrac® repositioning. A total of 17 patients were evaluated (one was lost to follow-up) using the BNI score for pain assessment and MRI with a median follow-up of 12 months. RESULTS: The quality criteria of geometric and dosimetric accuracy were met for the 6-mm cone but not for the 4-mm cone. All patients were treated with a 6-mm cone with a dose of 90Gy prescribed at the isocenter at the root entry zone. Initial pain control was obtained in 70.5% of our patients, and 53% maintained pain control with a median follow-up of 12 months. All recurrences occurred within 3 to 6 months after radiosurgery. No brainstem toxicity was observed. Six patients had non-disabling facial hypoesthesia, half of whom already had pretreatment hypoesthesia. CONCLUSION: The treatment of trigeminal neuralgia on a dedicated linear accelerator is a highly technical treatment whose accuracy and safety are paramount. The physical measurements allowed the commissioning of the technique with a 6mm cone. Our first clinical results are in accordance with the literature.

[Comparison of talonavicular-cuneiform joint fusion with bone grafting and without bone grafting in treatment of Müller-Weiss disease].

Objective: To compare the effectiveness of talonavicular-cuneiform joint fusion with iliac bone grafting and without bone grafting in the treatment of Müller-Weiss diseases (MWD). Methods: The clinical data of 44 patients (44 feet) with MWD who received talonavicular-cuneiform joint fusion between January 2017 and November 2022 and met the selection criteria was retrospectively analyzed. Among them, 25 patients were treated with structural iliac bone grafting (bone grafting group) and 19 patients without bone grafting (non-bone grafting group). There was no significant difference ( P>0.05) in age, gender composition, body mass index, disease duration, affected side, Maceira stage, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, anteroposterior/lateral Meary angle, and Pitch angle between the two groups. Operation time, operation cost, and postoperative complications were recorded in the two groups. AOFAS and VAS scores were used to evaluate the function and pain degree of the affected foot. Meary angle and Pitch angle were measured on the X-ray film, and the joint fusion was observed after operation. The difference (change value) of the above indexes before and after operation was calculated for comparison between groups to evaluate the difference in effectiveness. Results: The operation was successfully completed in both groups, and the incisions in the two groups healed by first intention. The operation time and cost in the bone grafting group were significantly more than those in the non-bone grafting group ( P<0.05). All patients were followed up. The median follow-up time was 41.0 months (range, 16-77 months) in the non-bone grafting group and 40.0 months (range, 16-80 months) in the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case, internal fixation stimulation in 2 cases, and pain at the iliac bone harvesting area in 1 case of the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case and muscle atrophy of the lower limb in 1 case of the non-bone grafting group. There was no significant difference in the incidence of complications between the two groups ( P>0.05). At last follow-up, the AOFAS scores of the two groups significantly improved when compared with those before operation, while the VAS scores significantly decreased, the anteroposterior/lateral Meary angle and Pitch angle significantly improved, and the differences were significant ( P<0.05). There was no significant difference in the change values of outcome indicators between the two groups ( P>0.05). There was no delayed bone union or bone nonunion in both groups, and joint fusion was achieved at last follow-up. Conclusion: In the treatment of MWD, there is no significant difference in effectiveness and imaging improvement of talonavicular-cuneiform joint fusion combined with or without bone grafting. However, non-bone grafting can shorten the operation time, reduce the cost, and may avoid the complications of bone donor site.

Balloon Pressure and Clinical Effectiveness of Percutaneous Microballoon Compression in the Treatment of Primary Trigeminal Neuralgia.

BACKGROUND: Primary trigeminal neuralgia (PTN) is a type of chronic neuropathic pain disorder caused by neurovascular compression. Percutaneous balloon compression (PBC) is a widely used method for the treatment of PTN. OBJECTIVES: To examine the correlation of balloon pressure (BP) during percutaneous microballoon compression (PBC) with postoperative pain relief and complications in the treatment of primary trigeminal neuralgia (PTN). STUDY DESIGN: Forty-five patients diagnosed with PTN and treated with PBC were recruited. The BP was recorded at 2 time points: when the balloon achieved the ideal pear shape (initial BP [IBP]) and when the pressure was maintained for 2 min (final BP [FBP]). SETTING: This study was conducted at the Department of Pain and Rehabilitation of the Second Affiliated Hospital at the University of South China in Hunan, China. METHODS: The patients' Barrow Neurological Institute (BNI) pain intensity score, BNI facial numbness score, masticatory muscle weakness score, and recurrence were recorded before and after surgery. The receiver operating characteristic (ROC) curves were generated for the IBP to predict treatment effectiveness, severe facial numbness, and severe masticatory muscle weakness. RESULTS: The BNI pain intensity score, BNI facial numbness score, and masticatory muscle weakness score were significantly decreased after surgery (all P < 0.001). IBP was positively correlated with the difference between IBP and FBP (P < 0.01). Both IBP and the difference between IBP and FBP were negatively correlated with the BNI pain intensity score and positively correlated with the BNI facial numbness score and masticatory muscle weakness score (P < 0.01). The IBP and the difference between the IBP and FBP were significantly lower in patients experiencing recurrence than in the nonrecurrent group (P < 0.05). The areas under the ROC curves of the IBP for predicting effective pain relief, severe facial numbness, and severe masticatory muscle weakness were 0.875, 0.980, and 0.988, respectively. LIMITATIONS: The sample size was relatively small, and the follow-up time was short. The correlations between the BP and other factors, such as filling amount, Meckel's cavity, and the size of the foramen ovale, were not investigated. The impact of the BP on long-term postoperative outcomes was not explored. CONCLUSIONS: An intraoperative BP of 138.65-153.90 KPa can be maintained for effective PBC treatment without causing serious complications.

VISIBL-MS: A bilingual educational framework to increase awareness of early multiple sclerosis.

BACKGROUND: Despite advancements in treatments of multiple sclerosis (MS), there is a lack of awareness of early MS symptoms, especially in students and the public, contributing to delays in diagnosis and treatment. This review aims to identify gaps in tools to increase awareness and to provide a bilingual framework to facilitate recognition of early MS symptoms. METHODS: We performed a literature review to determine the use of English and Spanish mnemonics in MS education for medical students and patients. RESULTS: There is no educational tool to help remember the early signs of MS at present. Here we present a framework for early awareness encompassed in the bilingual mnemonics VISIBLY (English) and VISIBLE (Spanish). VISIBLY stands for (1) Vision changes: Painful vision loss, loss of color vision or double vision; (2) Belly or Back numbness and Balance issues; (3) Limb weakness or Numbness; (4), Young people. Spanish version is included in the manuscript. CONCLUSION: We posit that VISIBL-MS provides a framework for MS awareness that addresses the interconnection between language, culture, health literacy, and health outcomes and can be a useful educational tool to tackle the effects of health literacy on diverse communities.

Type III Popliteal Artery Entrapment Syndrome with Concurrent Chronic Exertional Compartment Syndrome: A Case Report.

CASE: The patient, a 21-year-old female Division I track and field athlete, presents with bilateral calf pain, tightness, numbness, and swelling during activity. Initially diagnosed with chronic exertional compartment syndrome (CECS), she underwent bilateral four-compartment fasciotomies. After 4 months, she experienced persistence of some of her prefasciotomy symptoms and was referred to vascular surgery. A fibrous band was compressing the popliteal artery, making the diagnosis of popliteal artery entrapment syndrome (PAES). She underwent bilateral popliteal artery decompressions. She had a successful recovery with no recurrence of numbness, weakness, or pain. CONCLUSION: Recognize that structural PAES may coexist with CECS.

[Binocular loupe assisted mini-lateral and medial incisions in lateral position for release of elbow stiffness].

Objective: To analyze the effectiveness of binocular loupe assisted mini-lateral and medial incisions in lateral position for the release of elbow stiffness. Methods: The clinical data of 16 patients with elbow stiffness treated with binocular loupe assisted mini-internal and external incisions in lateral position release between January 2021 and December 2022 were retrospectively analyzed. There were 9 males and 7 females, aged from 19 to 57 years, with a median age of 33.5 years. Etiologies included olecranon fracture in 6 cases, elbow dislocation in 4 cases, medial epicondyle fracture in 2 cases, radial head fracture in 4 cases, terrible triad of elbow joint in 2 cases, supracondylar fracture of humerus in 1 case, coronoid process fracture of ulna in 1 case, and humerus fracture in 1 case, with 5 cases presenting a combination of two etiologies. The duration of symptoms ranged from 5 to 60 months, with a median of 8 months. Preoperatively, 12 cases had concomitant ulnar nerve numbness, and 6 cases exhibited ectopic ossification. The preoperative range of motion for elbow flexion and extension was (58.63±22.30)°, the visual analogue scale (VAS) score was 4.3±1.6, and the Mayo score was 71.9±7.5. Incision lengths for both lateral and medial approaches were recorded, as well as the occurrence of complications. Clinical outcomes were evaluated using Mayo scores, VAS scores, and elbow range of motion both preoperatively and postoperatively. Results: The lateral incision lengths for all patients ranged from 3.0 to 4.8 cm, with an average of 4.1 cm. The medial incision lengths ranged from 2.4 to 4.2 cm, with an average of 3.0 cm. The follow-up duration ranged from 6 to 19 months and a mean of 9.2 months. At last follow-up, 1 patient reported moderate elbow joint pain, and 3 cases exhibited residual mild ulnar nerve numbness. The other patients had no complications such as new heterotopic ossification and ulnar nerve paralysis, which hindered the movement of elbow joint. At last follow-up, the elbow range of motion was (130.44±9.75)°, the VAS score was 1.1±1.0, and the Mayo score was 99.1±3.8, which significantly improved when compared to the preoperative ones ( t=-12.418, P<0.001; t=6.419, P<0.001; t=-13.330, P<0.001). Conclusion: The binocular loupe assisted mini-lateral and medial incisions in lateral position integrated the advantages of traditional open and arthroscopic technique, which demonstrated satisfying safety and effectivity for the release of elbow contracture, but it is not indicated for patients with posterior medial heterolateral heterotopic ossification.

Rapid purification of alkylamides from Zanthoxylum bungeanum by medium-pressure liquid chromatography and the establishment of a numbness prediction model using an electronic tongue.

In the present study, an efficient and rapid method for the preparation of high-purity typical alkylamides from Zanthoxylum bungeanum (Z. bungeanum) pericarps using medium-pressure liquid chromatography (MPLC) was developed. Under the optimized conditions using a mobile phase of methanol : water (70 : 30, v/v) at a flow rate of 25 mL min-1 and one run for 30 min, hydroxy-α-sanshool with a purity of 97.85% could be obtained. Sensory evaluation and electronic tongue analysis of the hydroxyl-α-sanshool were performed, and the aftertastes of bitterness and astringency were found to be more representative of the compounds in Chinese prickly ash that causes numbness, which has not been reported in the literature before. An electronic tongue prediction model for the evaluation of numbing intensity was established: Y = 20.452X1 - 7.594X2 - 2.876, R2 = 0.973, where Y is a sensory evaluation value based on the 15 cm linear scale method and X1 and X2 are the aftertastes from astringency and bitterness, respectively. The evaluation model can be used for the evaluation of the numbing intensity of amides of Zanthoxylum bungeanum.

Effect of acupuncture combined with rehabilitation training on sensory impairment of patients with stroke: a network meta-analysis.

BACKGROUND: The refractory and disabling nature of sensory disorders after stroke seriously affects patients' daily lives and reduces hospital turnover. Acupuncture, as an alternative therapy, is commonly used in combination with rehabilitation training to improve sensory disorders. To compare the effects of different acupuncture-related treatments combined with rehabilitation training on sensory impairment and the daily living ability of patients with stroke, we conducted a network meta-analysis to provide evidence-based findings for clinical practice. METHODS: Randomized controlled trials on the treatment of sensory disorders in patients with stroke were systematically retrieved from several databases, including China National Knowledge Infrastructure (CNKI), China Science and Technology Journal(VIP), Wanfang Database, Chinese Biological Medical (CBM), PubMed, Embase, Web of Science, Cochrane Library, and Clinical trials. The retrieval period ranged from January 2012 to December 2023. Two independent reviewers screened the included literature, extracted the data, and assessed the risk quality using Cochrane Handbook 5.1.0 and ReviewManager 5.4.1. Stata16.0 software was employed for data analysis. The study protocol was registered in PROSPERO: CRD42023389180. RESULTS: After screening, 20 studies were included, involving a total of 1999 subjects. The network meta-analysis results indicate that, compared to standard rehabilitation, acupuncture plus massage plus rehabilitation showed the most significant reduction in Numbness Syndrome Scores (MD = -0.71(-1.11,-0.31)). Acupuncture combined with rehabilitation demonstrated the most substantial improvement in Sensory Impairment Scores (MD = -0.59,(-0.68,-0.51)) and daily living ability of patients (MD = 17.16,(12.20,22.12)). CONCLUSIONS: In comparison to standard rehabilitation, the combination of acupuncture-related treatments and modern rehabilitation training not only improves the symptoms of sensory impairment and numbness after stroke but also enhances the daily living ability of patients, especially when acupuncture is combined with rehabilitation. However, further demonstration is required to strengthen these conclusions.

Carpal tunnel syndrome secondary to a giant lipoma of the wrist and distal forearm.

In up to 2% of the population, benign tumours called lipomas can develop. When they are more than 5 cm, they are considered giant lipomas. Giant lipomas of the distal forearm and hand may cause compression to the underlying tissues, nerves and muscles, even though they are typically asymptomatic. An older woman with soft tissue swelling in her right wrist and forearm, and numbness and pain in her right hand presented to the general surgery outpatient clinic. Her numb fingers indicated that the median nerve was compressed, and an MRI scan of her wrist and forearm revealed median nerve compression due to a giant lipoma with a dimension of about 9.2×3.4×4 cm. A surgical excision was done with an intraoperative nerve stimulator, and the specimen sent for histopathology confirmed the diagnosis of lipoma. Pain, numbness and motor power improved within 1 week postoperatively, and the patient was discharged.

Analysis of the Therapeutic Efficacy of Percutaneous Balloon Double Compression for the Treatment of Recurrent Trigeminal Neuralgia.

BACKGROUND: A more secure and efficacious therapy than has been developed so far is imperative for patients suffering from recurrent trigeminal neuralgia (TN). Despite numerous reports on the use of enhanced percutaneous balloon compression (PBC) techniques, such as altering compression duration and balloon pressure, none have yielded satisfactory outcomes. With these issues in mind, we have employed the PBC double-compression technique for the first time. This technique involves initially inflating a balloon to expand the adhesive tissue in Meckel's lumen, followed by emptying of the contrast medium and subsequent slight catheter adjustment for further compression. The total duration of compression remains unchanged and may even be shortened. OBJECTIVES: The objective of this study was to assess the clinical effectiveness of the PBC double-compression technique in patients with recurrent TN and to analyze the technique's efficacy, subsequent duration of patients' facial numbness, and other complications. STUDY DESIGN: Retrospective study. SETTING: A single-center study. METHODS: Retrospective analysis was conducted on clinical data from 125 patients with postoperative recurrent TN who underwent double compression of the PBC and 65 patients who underwent single compression of the PBC between August 2017 and April 2022. The Barrow Neurological Institute Pain Intensity (BNI-P) score was utilized to quantify the severity of pain, while the Barrow Neurological Institute Facial Numbness (BNI-N) score was employed to separately evaluate the extent of postoperative pain relief and facial numbness. RESULTS: The BNI-P and BNI-N scores before and after PBC treatment are presented herein. At T0, there was no significant difference in the BNI-P scores between the single-compression group and the double-compression group; however, at T1-T4, the BNI-P scores of the double-compression group were lower than those of the single-compression group (P < 0.05). There was no significant difference in BNI-P scores between the 2 groups at T5. At T1-T4, the BNI-N score of the double-compression group was significantly lower than that of the single-compression group (P < 0.05). However, there was no significant difference in BNI-N score between the double and single compression groups at T5. In the single-compression group, one patient (1.5%) experienced insignificant pain relief on postoperative day one, while 2 patients (3.1%) suffered from pain recurrence during the 1-4-year follow-up period. Similarly, in the double-compression group, one patient (0.8%) had inadequate pain relief on postoperative day one, and 3 patients (2.4%) experienced pain recurrence during the same follow-up period. The remaining patients did not require further surgical intervention but continued to rely on regular oral analgesia. In the single-compression group, masticatory muscle weakness was observed in 50 cases (76.9%), while in the double-compression group, it was observed in 92 cases (73.6%). Perioral herpes affected 4 patients (7.1%) and 6 patients (4.8%) in the single- and double-compression groups, respectively. Facial hematoma occurred in 7 cases (10.8%) and 13 cases (10.4%) of the single- and double-compression groups, respectively; each group included one patient suffered who from diplopia. Notably, none of the patients in this study reported any instances of corneal anesthesia, anesthesia pain, aseptic meningitis, cerebrospinal fluid leakage, subarachnoid hemorrhage, carotid-cavernous fistula, or mortality. LIMITATIONS: This was a single-center retrospective study with a small sample size and relatively short follow-up time. Therefore, further evaluation of the long-term efficacy of PBC for postoperative recurrent TN is needed from multiple centers with larger sample sizes and longer follow-up periods. CONCLUSIONS: The double PBC method boasts a high cure rate, a low recurrence rate, and minimal complications, rendering the option appropriate for patients with recurrent TN and thus deserving of clinical promotion.

Pain Characteristics of Patients With Fibromyalgia: A Comparison Between Gender and Different Emotional States.

BACKGROUND: Generalized pain is the core symptom of fibromyalgia (FM). Few studies have described FM's different pain characteristics under various conditions. OBJECTIVE: To explore the pain characteristics of patients with FM of different gender and emotional states. STUDY DESIGN: A cross-sectional study. SETTING: A medical center in Beijing, People's Republic of China. METHODS: A total of 197 patients with FM were recruited from an outpatient clinic. Three distinct instruments were used to assess their pain characteristics: the Numeric Rating Scale (NRS-11) to assess pain severity, the Widespread Pain Index (WPI) to assess the number of pain regions, and the Short Form-McGill Pain Questionnaire-2 (SF-MPQ-2) to assess pain qualities. The Zung Self-Rating Anxiety Scale and Zung Self-Rating Depression Scale were used to assess patients' emotional states. An independent 2-sample t test, chi-squared test, and Mann-Whitney U test were used to analyze gender pain characteristics differences and different emotional states (with/without anxiety, with/without depression). RESULTS: Pain severity on the NRS-11 was 7 (5-8), the number of pain regions determined by WPI was 13 (10-16), and the total score of different pain qualities from the SF-MPQ-2 was 2.36 (1.68-3.73) in all patients with FM. The most frequently reported regions of pain were the right shoulder girdle (89.34%), left shoulder girdle (88.32%), upper back (85.28%), and neck (81.73%). The most frequently reported pain qualities were tiredness/exhaustion (97.46%), aching pain (94.42%), numbness (78.68%), cold/freezing pain (75.63%), and tenderness (75.13%). Women patients reported more severe pain and numbness, less frequent chest pain, and shooting pain than men patients did. Patients with FM and anxiety experienced more frequent and more severe feelings of punishing/cruel thoughts, fearfulness, sickening, and tenderness; more frequent jaw pain and cold-freezing pain; more severe pain caused by light touch and tiredness/exhaustion; less frequent lower leg pain than those without anxiety did. Patients with FM and depression reported more frequent and more severe pain caused by light touch; more frequent tenderness; more severe feelings of tiredness/exhaustion, sickening,fearfulness, and punishing/cruel thoughts; and less frequent and less severe piercing pain than those without depression did. LIMITATIONS: The limitations of this study are its single-center design and lack of objective pain indicators. CONCLUSION: Gender significantly affected pain severity, chest pain, numbness, and shooting pain. Jaw pain, lower leg pain, cold/freezing pain, tenderness, pain caused by light touch, piercing pain, and pain-affective descriptors are closely related to emotional states in FM. A comprehensive understanding of pain characteristics in patients with FM would be helpful for disease education, diagnosis, and treatment.

[Clinical features of peripheral neuropathy with livedo reticularis: an analysis of seven cases].

The clinical characteristics, auxiliary examinations, skin and neuropathological features of 7 patients who had reticular cyanosis with peripheral neuropathy from the Department of Neurology, Huashan Hospital, Fudan University from January 2019 to December 2022 were retrospectively analyzed. Among the 7 patients, 5 were female and 2 were male.The age of onset of peripheral neuropathy was (39.8±21.3) years and the disease duration of peripheral neuropathy was (2.7±2.3) years. Three patients had acute onset and 4 patients had chronic onset. All the patients had limb numbness, with limb weakness in 6 patients and pain in 5 cases. Neuroelectrophysiological examination revealed 1 case of mononeuropathy, 2 cases of polyneuropathy, 2 cases of peripheral neuropathy, and 2 cases of sensory neuron neuropathy. Skin biopsy was performed in 3 patients, which presented hyperplasia and expansion of blood vessels in the dermis with lymphocyte infiltration. Nerve biopsy was performed in 3 patients, indicating axonal damage. Reticular cyanosis with peripheral neuropathy characterizes with numbness and weakness of limbs, most of which were accompanied by pain. Electrophysiological changes are in various forms. The pathological changes are dominated by the damage of axonal.

Mottled Raynaud's phenomenon and hand-arm vibration syndrome: followed up for 10 years.

Vibration white finger is a form of secondary Raynaud's phenomenon (RP) caused by the use of handheld vibrating tools. RP usually appears on the extremities of the fingers, and its borders are well recognised. No reports have been published on 'mottled' RP in continuous observation from the onset to the disappearance of RP. A man in his 60s who had been using vibrating tools such as jackhammers and tampers for 30 years presented with sensations of coldness, burning and numbness. Whole-body cold exposure was performed outdoors in winter, and RP was photographed continuously. 'Mottled' RP can be defined as triphasic colour changes: white, blue and red. The patient was taken off work, kept warm and medicated. His symptoms improved slightly after 10 years of follow-up, but the RP did not disappear. 'Mottled' RP is rare and refractory and should be recognised as a form of RP.
