RESUMO
PURPOSE: This study aims to aggregate and analyze existing clinical evidence to compare the efficacy and adverse effects of unilateral or bilateral botulinum toxin injections for the treatment of adductor spasmodic dysphonia (ADSD). METHODS: Reports from non-randomized controlled trials and cohort studies pertaining to the efficacy and adverse effects of unilateral and bilateral botulinum toxin injections for ADSD were identified and retrieved from four electronic databases from inception to July 2023. The meta-analysis employed fixed or random effects models to assess pooled relative risks (RR), mean differences (MDs), and standard mean differences (SMDs) with their corresponding 95% confidence intervals (CIs). RESULTS: We included two non-randomized controlled trials and seven cohort studies comprising 854 total patients. Meta-analysis of the included studies showed that bilateral botulinum toxin injections associated with a longer duration of vocal improvement (MD = - 2.89, 95% CI - 3.13 to - 2.65, I2 = 0%, P < 0.00001). However, bilateral botulinum toxin injections associated with an increase in adverse effects, including a longer duration of breathy voice quality (SMD = - 0.51, 95% CI - 0.79 to - 0.22, I2 = 35%, P = 0.0005) and a higher occurrence of swallowing difficulties (RR = 0.46, 95% CI 0.35 to 0.11, I2 = 0%, P < 0.00001). CONCLUSION: Bilateral botulinum toxin injections for ADSD showed a longer duration of vocal improvement, a longer breathy voice duration and a higher dysphagia occurrence and duration than unilateral injections.

BACKGROUND: Knee osteoarthritis (KOA) is a common disabling joint disease that affects millions of people worldwide. Diet may play a role in the etiology and progression of KOA, but evidence for a causal relationship is limited. We aimed to investigate the causal impact of dietary intake on KOA risk using Mendelian randomization (MR). METHODS: We used summary-level data from genome-wide association studies (GWAS) including dietary intake (n = 335, 394-462, 342), and KOA (n = 403, 124). We selected 6-77 genetic variants as instrumental variables for 18 dietary factors, including processed meat, poultry, beef, oily fish, non-oily fish, pork, lamb, frequency of alcohol intake, alcoholic beverages, tea, coffee, dried fruit, cereals, cheese, bread, cooked vegetables, salad/raw vegetables, and fresh fruit. We performed univariate and multivariate MR analyses to estimate the causal effect of each dietary factor on KOA risk. We also performed some sensitivity analyses to assess the validity of the MR hypothesis. RESULTS: We found that higher coffee intake was associated with increased KOA risk, whereas higher intake of dried fruits, grains, cheese, and oily fish was associated with reduced KOA risk. After multivariate adjustment, we found that coffee and oily fish intake may affect KOA through obesity, body mass index (BMI), diabetes, hypertension, and prolonged standing. Sensitivity analyses did not reveal any evidence of pleiotropy. CONCLUSIONS: Our study provides new causal evidence that dietary intake may influence KOA risk. Specifically, we suggest that increased intake of dried fruits, grains, cheese, and oily fish and decreased coffee intake may be beneficial in preventing and mitigating KOA. further studies are needed to elucidate the underlying mechanisms and to confirm our findings in different populations.

BACKGROUNDS: Allergic rhinitis (AR) is a non-infectious chronic inflammation of the nasal mucosa mainly mediated by immunoglobulin E (IgE) in atopic individuals after exposure to allergens. The application of AR guideline-recommended pharmacotherapies can rapidly relieve symptoms of AR but with poor long-term efficacy, and many of these therapies have side effects. Many natural products and their derivatives have shown potential therapeutic effects on AR with fewer side effects. OBJECTIVES: This review aims to expand understanding of the roles and mechanisms of natural compounds in the treatment of AR and to highlight the importance of utilizing natural products in the treatment of AR. MATERIAL AND METHOD: We conducted a systematic literature search using PubMed, Web of Science, Google Scholar, and Clinical Trials. The search was performed using keywords including natural products, natural compounds, bioproducts, plant extracts, naturally derived products, natural resources, allergic rhinitis, hay fever, pollinosis, nasal allergy. Comprehensive research and compilation of existing literature were conducted. RESULTS: This article provided a comprehensive review of the potential therapeutic effects and mechanisms of natural compounds in the treatment of AR. We emphasized that natural products primarily exert their effects by modulating signalling pathways such as NF-κB, MAPKs, STAT3/ROR-γt/Foxp3, and GATA3/T-bet, thereby inhibiting the activation and expansion of allergic inflammation. We also discussed their toxicity and clinical applications in AR therapy. CONCLUSION: Taken together, natural products exhibit great potential in the treatment of AR. This review is also expected to facilitate the application of natural products as candidates for treating AR. Furthermore, drug discovery based on natural products has a promising prospect in AR treatment.

BACKGROUND: Functional endoscopic sinus surgery is a principal option for treating chronic rhinosinusitis with nasal polyps (CRSwNP) after medication failures. Unfortunately, some patients still have unsatisfactory postoperative recovery. The type of inflammatory cell infiltration in nasal polyp tissue has been reported available for recurrence prediction. As it is invasive and time-consuming, this technique is hard to promote clinically under the existing technical conditions. And during the course of clinical treatment, we have noted that differences in the postoperative recurrence rate of patients present among different traditional Chinese medicine syndrome types. METHODS AND ANALYSIS: This is a non-randomized, single-center, and prospective cohort study started in Chengdu Sichuan Province, People's Republic of China, in January 2021. A total of 200 participants will be recruited from patients who are diagnosed with CRSwNP and prepared for functional endoscopic sinus surgery. We collect preoperative data which includes general information, medical history, TCM syndromes, visual analogue scale (VAS) of subjective symptoms, Lund-Kennedy endoscopic score, and Lund-Mackay score of computed tomography (CT) scanning of sinuses. We acquire the VAS score and Lund-Kennedy score of subjective symptoms through multiple planned follow-up after surgery. After 1 year of follow-up, the recurrence rate will be calculated, and the curative effect will be assessed. Meanwhile, the patients' pathological sections will be sorted out, and inflammatory cell infiltration will be analyzed. Statistical analysis will be carried out to evaluate the correlation among CRSwNP recurrence and TCM syndrome types and tissue inflammatory cell infiltration types. Then we will establish a predictive model for CRSwNP recurrence. Analyses of survey data include descriptive and inferential statistical approaches. DISCUSSION: This is the first prospective cohort study on investigating the correlation of CRSwNP recurrence with TCM syndrome types and tissue inflammatory cell infiltration types. Through this study, we hope to discover a new and simple, effective, and noninvasive way to predict the recurrence rate rapidly after CRSwNP and provide reference for the intervention timing of traditional Chinese medicine application, thereby achieving customized diagnosis and treatment, minimizing risks of surgical events, and delaying postoperative recurrence of CRSwNP.

Background: Previous epidemiological and other studies have shown an association between ischemic stroke (IS) and frozen shoulder (FS). However, the causal relationship between them remains unclear. Therefore, the present study aimed to investigate the causal relationship between IS and FS using a two-sample Mendelian randomization method. Methods: Our research was divided into two stages: discovery and replication. The data were extracted from publicly available genome-wide association studies (GWAS). We selected a large sample of IS (n = 440, 328) and its subtypes (large-artery atherosclerotic stroke (LAS), cardioembolic stroke (CES), and stroke caused by small-vessel disease (SVS) and lacunar stroke (n = 254, 959) as exposure data. Additionally, we selected a large sample of FS as outcome data (n = 451, 099). Inverse variance weighting (IVW) was applied as the primary analysis method. The weighted median, MR-Egger, simple model, and weighted model were used as complementary analysis methods to assess causal effects. Moreover, heterogeneity was analyzed using Cochran's Q-test with IVW and MR-Egger. The MR-Egger intercept and MR-PRESSO analysis methods were used for pleiotropy testing. The stability of the results was also assessed using a leave-one-out analysis. Results: In the discovery stage, the IVW approach revealed an odds ratio (OR) of 1.207 with a 95% confidence interval (CI) of 1.027-1.417 and a P-value of 0.022. This suggests a causal association between IS levels and an increased risk of FS. In the subtype studies of IS, the findings were negative. However, during the replication stage, a significant causal link was found between selected lacunar strokes and FS with an OR of 1.252, a 95% CI of 1.105-1.419, and a P-value of 0.0004. All studies had no pleiotropy or heterogeneity, and the findings were robust. Conclusions: Our study confirmed the causal relationship between any IS level and increased risk of FS. Furthermore, the same results were obtained in the replication stage with lacunar stroke as an exposure factor. However, there was no direct causal relationship between the subtypes of IS and FS. Our study provides theoretical support for shoulder care for patients with IS.
RESUMO
Objective: The objectives of this study were to analyze rhinogenic headache, i.e., noninflammatory frontal sinus headache, a headache caused by bony obstruction of the frontal sinus drainage channels that receives relatively insufficient attention clinically, and to propose endoscopic frontal sinus opening surgery as a treatment based on the etiology. Study Design: Case series. Setting: From the data of patients with noninflammatory frontal sinus headache who underwent endoscopic frontal sinus surgery in Hospital of Chengdu University of Traditional Chinese Medicine during 2016-2021, data for three cases with detailed postoperative follow-up data were extracted for case series reports. Methods: This report provides detailed information on three patients with noninflammatory frontal sinusitis headache. Treatment options include surgery and rechecking, with the visual analogue scale (VAS) scores of preoperative and postoperative symptoms, CT, and endoscopic images. Three patients had common characteristics: the clinical manifestations were recurrent or persistent with pain and discomfort in the forehead area, but there was no nasal obstruction or runny nose; the paranasal sinus CT revealed no signs of inflammation in the sinuses but suggested bony obstruction of the drainage channel of the frontal sinus. Results: All three patients had recovery from headache, nasal mucosal recovery, and patent frontal sinus drainage. The recurrence rate of forehead tightness and discomfort or pain was 0. Conclusion: Noninflammatory frontal sinus headache does exist. Endoscopic frontal sinus opening surgery is a feasible treatment modality that can largely or even completely eliminate the stuffy swelling and pain in the forehead. The diagnosis and surgical indications for this disease are based on a combination of anatomical abnormalities and clinical symptoms.
RESUMO
Objective: This randomized controlled trial aimed to evaluate the clinical efficacy of acupuncture combined with voice training for treating patients with primary muscular tension dysphonia (MTD) (Qi stagnation and blood stasis type in traditional Chinese medicine). Methods: A total of 108 patients with primary MTD (Qi stagnation and blood stasis type) were recruited in this study. The participants were randomly divided into 3 equal groups: a test group and two control groups (control groups 1 and 2). An additional 38 participants without primary MTD were recruited as the healthy group. Control group 1 received acupuncture sessions 3 times per week on alternate days on the Hegu (LI 4), Taichong (LR 3), Open Voice No. 1 point, and Open Voice No. 2 points. Control group 2 received a 40-minute voice training session once weekly. The test group received both treatments. The total treatment course for all groups was 30 days. The healthy participants did not receive any interventions. The physiological and functional voice improvements after treatment were compared between all 3 MTD groups and healthy participants. The Voice Handicap Index (VHI-10), the VHI-10 emotional score, the Chinese Medicine Symptom Score Scale (TCM), and the Grade Roughness Breathiness Asthenia Strain (GRBAS) were used to evaluate the changes in the voice after treatment. A laryngeal muscle blood oxygen monitoring was used to measure the blood oxygen saturation (SO2) of the suprahyoid and infrahyoid muscles, and a stroboscopic laryngoscopy was used to measure the dysphonia severity index (DSI). Acoustic voice analysis was used to measure the maximum phonation time (MPT), the jitter, and the shimmer. Result: The SO2 levels of the laryngeal muscle were significantly higher in the healthy subjects than in pretreatment MTD patients and were correlated with the VHI-10 and DSI scores. A significant improvement in the physiological and functional scores, the total VHI-10, the GRBAS score, the voice acoustic analysis indices, MPT, jitter, shimmer, and DSI, was noted after treatment in all 3 MTD groups (P < 0.05). However, the posttreatment scores in the test group were significantly higher compared to control group 2, whose score were superior than that in control group 1 (P < 0.05). Both the test group and control group 1 showed a significant increase in the SO2 levels of the laryngeal muscles after treatment, where the test group had a higher elevation than control group 1. No significant difference was noted in the posttreatment SO2 of the laryngeal muscles in control group 2 (P > 0.05). Conclusion: Acupuncture monotherapy or in combination with voice training can reduce the anxiety emotion, relieve MTD-associated systemic symptoms, and increase the SO2 levels of the laryngeal muscle. This combination is a promising approach for the treatment of MTD. This trial is registered with ChiCTR2200061469.
RESUMO
AIM: Recurrent episodes of chronic tonsillitis (CT) can affect a patient's quality of life, physical and mental health. Clinicians often perform surgeries to remove them. Traditional surgical methods are varied, despite their advantages. However, this remains controversial. This study aimed to examine both the safety and efficacy of low-temperature plasma tonsillectomy (LTPT) in treatment of chronic tonsillitis, which may provide a substitute for clinicians and compensate for the short supply of therapeutic procedures. METHODS AND ANALYSIS: This protocol is guided by the Preferred Reporting Items for Systematic. REVIEW AND META-ANALYSIS: Protocols (PRISMA-P) and by the Cochrane Collaboration Handbook. We will formulate strict inclusion and exclusion criteria in English databases (PubMed, EMBASE, and Web of Science) and search literature in different clinical registration platforms (Cochrane Library). The including articles were evaluated by the Cochrane RCT evaluation criteria. The primary main endpoints will include the duration of operation, blood loss during surgery, time of formation and exfoliation of the pseudomembrane, average pain and duration post-operation, and time for normal diet. The Secondary endpoints will include complications of postoperative bleeding and infection. Stata 15.0 will be used for data analysis. Subgroup analysis, sensitivity analysis, and meta-regression were used to detect the sources of heterogeneity. Begg's Test will quantitatively detect publication bias quantitatively. ETHICS AND DISSEMINATION: The results of this meta-analysis and meta-regression will be disseminated through publication in a peer-reviewed journal. The data used in this meta-analysis will not contain individual patient data; therefore, ethical approval is not required. KEY WORDS: Chronic tonsillitis, Low-temperature plasma tonsillectomy, Meta-analysis, Protocol, Systematic review.

INTRODUCTION: Benign fibrous histiocytoma (BFH) is a mesenchymal tumor composed of fibroblasts and histiocytes, which normally occurs in the bone tissue and/or the skin of the limbs. BFH of the nasal septum is rare worldwide. PATIENT CONCERNS: A 38-year-old female patient attended our clinic with congestion in her right nasal cavity. DIAGNOSES: Endoscopic examination revealed a mass within the right nasal passage. Immunohistochemical staining demonstrated cells labeled with VIM (+), CD68PGM1 (+), CD34 (-), Actin (-), PCK (-), EMA (-), Desmin (-), SMA (-), S-100 (-), P63 (-), ALK-1 (-), beta-catenia (+), and KI67 (+). Clinical and histopathological examinations showed that the mass was a septum-originated BFH. INTERVENTIONS: For the treatment of BFH of the nasal septum, the mass was removed endoscopically using a transnasal approach. OUTCOMES: No recurrence was observed over 30 months of follow-up. CONCLUSION: To prevent the recurrence wide local resection with histological clear margin and long-term follow-up with an endoscope are necessary.
