To summarize the imaging features of congenital branchial anomalies (CBA) in children based on a large single‑center cohort, propose cohort-based stratified diagnostic criteria and individualized surgical strategies, and provide a reference for the precise clinical management of pediatric CBA. A retrospective study analyzed 1,668 pediatric CBA at the Children’s Hospital of Zhejiang University between January 2017 and December 2024. Data regarding gender, age, lesion laterality, infection history, lesion type, imaging features, and treatment regimens were summarized and evaluated. The cohort included 936 males (56.1
Background In pediatric patients, nasal polyps primarily manifest as anthrochoanal polyps (ACP) or chronic rhinosinusitis with nasal polyps (CRSwNP). This study compares the histopathological differences between pediatric ACP and CRSwNP, analyzes pathological indicators associated with postoperative recurrence and provides evidence for subtype-specific diagnosis and treatment. Materials and methods This retrospective study analyzed demographic factors, comorbidities and a structured histopathologic report of six variables from 172 pediatric patients (86 with ACP and 86 with CRSwNP) who underwent functional endoscopic sinus surgery. Differences between recurrent and non-recurrent presentations were further examined. Results Mean age in the ACP group was significantly lower than the CRSwNP group (p=0.007). The CRSwNP group exhibited higher overall severity of inflammation (38.3% v.s. 18.6%, p=0.010). The ACP group showed greater subepithelial edema (65.1% v.s. 37.2%, p<0.001). In the ACP group, the overall degree of inflammation correlated significantly with inflammatory type, and severity of subepithelial edema correlated with collagen deposition. In the CRSwNP group, overall severity of inflammation correlated with eosinophil count per high power field and inflammatory predominance. In the ACP group, the proportion of collagen deposition was significantly lower in recurrent cases (5.6% v.s. 44.1%, p=0.004). In the CRSwNP group, the overall degree of inflammation was significantly higher in recurrent cases (46.7% v.s. 36.6%, p=0.003). Conclusion Pediatric ACP is characterized by prominent subepithelial edema. A lack of collagen deposition indicates a higher risk of recurrence. CRSwNP features severe inflammation, which positively correlates with recurrence.
Laryngeal squamous cell carcinoma (LSCC) is one of the major malignant cancers worldwide. Emerging evidence has demonstrated that N6-methyladenosine (m6A) modification affects gene expression by regulating RNA metabolic processes, dynamically and reversibly regulated by its "writers", "erasers" and "readers". m6A modification plays an important role in the occurrence and development of various tumors. Recent studies have shown that m6A modifications are abnormally expressed in LSCC cells and tissues and participate in the malignant phenotypes of LSCC including cell proliferation, invasion, metastasis and chemotherapy resistance by mediating m6A regulators. This fundings may provide new directions for the molecular classification and targeted treatment of LSCC. In this review, we will focus on the molecular mechanism and potential clinical function of m6A modification in LSCC and emphasize its potential as a biomarker for the clinical diagnosis, prognosis, and treatment of LSCC.
This study aimed to examine the ultrasound imaging characteristics of congenital branchial cleft anomalies (BCAs) in children and their clinical applications, providing a minimally invasive method for preoperative evaluation and treatment. This single-centre retrospective study (July 2021–April 2024) analysed 308 paediatric BCA cases. Clinical, intraoperative, and ultrasound data were compared to establish imaging criteria and inform management. Among the 308 patients (mean age 6.45 ± 5.24 years), 8 were neonates. Unilateral anomalies were observed in 282 patients (right: 68, left: 214), whereas bilateral anomalies were observed in 26 patients. The male-to-female ratio was 1:1.3. First branchial cleft anomalies (FBCAs) developed in 84 patients (27.2
OBJECTIVE:To identify risk factors for secondary post-tonsillectomy hemorrhage (SPTH) in pediatric patients undergoing Coblation procedures and develop a predictive model to support perioperative management. METHODS:A retrospective analysis was performed on 15,729 children who underwent low-temperature Coblation tonsillectomy at the Children's Hospital, Zhejiang University School of Medicine, between June 2019 and June 2024. Univariate and multivariate analysis were employed to identify factors associated with the occurrence of SPTH. A prediction model was developed based on the identified independent risk factors. To enhance the model's predictive performance and calibration, Weighted Logistic Regression was applied to construct a Nomogram model. The model was validated and evaluated using bootstrap resampling, the consistency index (C-index), Receiver Operating Characteristic (ROC) curve, and Brier Score. RESULTS:Among the 15,729 patients, 9834 (62.52 %) were boys, and 5895 (37.48 %) were girls.The mean age was 6.55 ± 2.38 years, and the average length of hospitalization was 3.94 ± 1.51 days. Among the 15,729 children, 235 (1.5 %) experienced SPTH, and 42 (0.3 %) required additional general anesthesia for surgical hemostasis. Univariate analysis identified that gender, age, surgical indication, degree of tonsillar embedding, Body Mass Index (BMI), postoperative diet, and surgeon experience were significantly associated with SPTH (P < 0.05).Multivariate logistic regression analysis revealed that severe tonsillar embedding, junior surgeon, obesity, poor postoperative diet, and age ≥12 years were independent risk factors for SPTH. A Nomogram model was developed based on these independent risk factors. The model was internally validated using bootstrap resampling (1000 iterations). The results showed that the C-index was 0.817, indicating good calibration and stability; ROC curve analysis revealed an Area Under the Curve(AUC)of 0.816, demonstrating strong discriminatory ability; and the Brier Score was 0.0155, indicating minimal error between predicted probabilities and actual outcomes. CONCLUSION:Severe tonsillar embedding, junior surgeon, obesity, poor postoperative diet, and age ≥12 years are independent risk factors for Coblation SPTH in children. The Nomogram model can quickly and efficiently calculate the bleeding rate of SPTH in children, providing valuable guidance for clinical practice.
OBJECTIVE:To evaluate device survival and identify risk factors for failure in pediatric cochlear implant (CI) surgery to guide strategies for minimizing failure rates and improving survival outcomes. METHODS:A retrospective analysis was conducted on pediatric patients who underwent CI surgery at the Children's Hospital, Zhejiang University School of Medicine, from September 2008 to September 2023. Device survival was assessed using the Kaplan-Meier method while independent factors influencing device survival were analyzed using the log-rank test and Cox regression model. RESULTS:Among 602 children, the mean age at first CI surgery was 50.3 months (range = 8-155 months). The cohort included 353 males (58.6%) and 249 females (41.4%). Revision surgery was required in 28 cases (4.7%), primarily due to device failure (17/28, 60.7%), including 14 hard and 3 soft failures. Kaplan-Meier analysis showed CI survival rates of 99.1%, 98.1%, 96.7%, 96.4%, and 96.4% at 1, 2, 3, 5, and 10 years post-surgery, respectively. The log-rank test identified sex, age, and history of head trauma as significant factors affecting device survival (P < .05). Multivariate Cox regression confirmed that male sex, first implantation ≤3 years of years, and postoperative head trauma were independent risk factors for device failure. CONCLUSIONS:Pediatric cochlear implantation is generally safe and effective, though device failure remains a concern, necessitating revision surgery remains. Male children who undergo cochlear implantation at ≤3 years of age or have a history of postoperative head trauma require enhanced postoperative care. This includes avoiding vigorous head impacts and increasing follow-up visits to monitor device function and speech recovery. Manufacturers should prioritize developing more durable, impact-resistant cochlear implants to reduce failure rates and improve long-term device survival.
BackgroundKnee osteoarthritis (KOA) is a prevalent osteoarthritic disorder. Although acupuncture is increasingly used in clinical practice for KOA management, its efficacy remains to be further optimized. ObjectiveThis trial aims to evaluate the efficacy and safety of acupuncture at sensitized acupoints for the treatment of KOA. MethodsWe will recruit 350 patients diagnosed with KOA from 3 clinical centers in this single-blind, sham-controlled, randomized controlled trial. Participants will be randomized to receive either acupuncture at 5 high-probability sensitized acupoints or sham acupuncture with nonpenetrative needling using Takakura acupuncture simulation devices. Both groups will receive 24 sessions over 8 weeks, followed by a 16-week posttreatment follow-up period. The primary outcome is the proportion of responders, defined as a reduction of 2 or more points in the Numeric Rating Scale score at week 8. Secondary outcomes include changes in scores on validated scales for KOA severity, walking distance, disability, depression, anxiety, insomnia, and pain self-efficacy. Adverse events will be documented for safety evaluation. ResultsThe first participant was enrolled on February 15, 2025, and by June 28, 2025, we had enrolled 25 patients. Data analysis has not yet been initiated. The completion of data collection is anticipated by March 2026. ConclusionsThis trial aims to provide confirmatory and exploratory evidence regarding the efficacy and safety of sensitized acupoint-based acupuncture for treating KOA. If the hypothesized benefits are substantiated, sensitized acupoint-based acupuncture could emerge as a complementary and alternative therapy for KOA, potentially reducing reliance on medication and mitigating drug-related adverse effects.

Sensorineural deafness is a hearing impairment resulting from damage to the auditory nerve or inner ear hair cells. Currently, cochlear implants (CIs) are widely used as hearing aids for sensorineural deafness patients. A fundamental limitation of cochlear implants (CIs) is that spiral ganglion neurons (SGNs) cannot be replenished. This greatly restricts the rehabilitation of sensorineural deafness. Additionally, the insertion of CIs can cause secondary cochlear damage, worsening the condition of the patients' cochlear. Therefore, a new type of neural stem cells (NSCs) loaded graphene oxide-polyaniline/GelMA (GO-PAni/GelMA) conductive hydrogel electrode for cochlear implant was fabricated via in-situ radical polymerization and cyclic UV curing technique. On the one hand, the hydrogel electrode, as a direct contact layer, helps to avoid the physical hurt for cochlear. On the other hand, NSCs were supplemented via the hydrogel carrier and neuronal differentiation was induced by electrical stimulation, which was validated by the experimental results of immunofluorescence, Phalloidin Staining and RT-qPCR. Furthermore, based on RNA sequencing and transcriptome analysis, we hypothesized that the neuronal differentiation of NSCs was adjusted by the calcium signaling pathway and GABAergic synapse. Overall, our cell loading conductive hydrogel electrode may be an effective solution to sensorineural deafness. The revelation of the mechanism of neuronal differentiation promoted by electrical stimulation provides a basis for further sensorineural deafness treatment using conductive hydrogel CI electrode.
Pediatric chronic sinusitis (CRS) is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.
Objective This systematic review of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of moxibustion as a complementary or alternative treatment for asthma. Methods Seven databases were searched up to June 23, 2024, to identify RCTs assessing moxibustion for bronchial asthma. The outcomes of interest included response to treatment, asthma control, quality of life, lung function, immunological indicators, and incidence of adverse events (AEs). The treatment effects were measured by proportional odds ratios or mean differences with 95% confidence intervals. Results Thirty-seven RCTs (n = 2,879) were included. Moderate- to very low-quality evidence showed that compared with anti-asthmatic drugs alone, moxibustion plus anti-asthmatic drugs led to a significantly better response and greater increases in lung function, asthma control, and IgE levels. However, the combination therapy had no effect on children’s quality of life. In the active comparisons, moxibustion resulted in a superior response to treatment and a greater improvement in asthma control and had comparable effects on lung function, quality of life, and IgE levels compared with anti-asthmatic drugs. The effects of moxibustion on the proportions of CD4 + and CD8 + T cells and the eosinophil count were inconsistent between the add-on and active comparisons. All reported AEs related to moxibustion were mild. Conclusions Moxibustion, as an adjunctive treatment or used alone, may improve the response to treatment, lung function, asthma control, and IgE levels in patients with asthma with good safety. Its effects on children’s quality of life and immune cell levels remain uncertain.
Objective: The aim of this study was to summarize the clinical features of congenital preauricular fistula (CPF) in pediatric patients to improve the levels of diagnosis and treatment, reduce the rates of missed diagnosis and recurrence, and shorten the total diagnosis and treatment time.Methods: A total of 353 patients with CPF who were admitted to the Department of Otolaryngology in The Children's Hospital, Zhejiang University School of Medicine between January 2019 and December 2021 was enrolled in this retrospective observational study. Follow ups for 12-42 months were performed to investigate the classification, surgical methods, and postoperative conditions of CPF and to compare the recurrence rate, complication rate, and total diagnosis and treatment time between the active infection CPF group (AICPFG) and infection-controlled/non-infected CPF group (IC/NICPFG).Results: In 316 cases (89.5%) out of the 353 patients, the natural fistula orifice was located in front of the crus helicis; in 33 cases (9.4%), the natura fistula orifice was located at the crus helicis; and in 4 cases (1.1%), the natura fistula orifice was located in the external acoustic meatus. The AICPFG had 52 cases (14.7%), including 1 case (0.28%) of recurrence and 2 cases (0.56%) of infection at the incision site. The IC/NICPFG had 301 cases (85.3%), including 4 cases (1.13%) of recurrence, 6 cases (1.7%) of infection at the incision site, and 1 case (0.28%) of scar formation at the incision site. There were no significant differences in the recurrence rates and postoperative complications between the AICPFG and IC/NICPFG (p > 0.05). There was a statistically significant difference in the total diagnosis and treatment time between the AICPFG and IC/NICPFG (p < 0.05). Conclusion: A reasonable classification of CPF, use of appropriate surgical methods, and belonging to the AICPFG do not increase the recurrence and complication rates of children but shorten the total treatment course, relieve patients' suffering, reduce treatment costs, and achieve a better clinical prognosis.
Objective To investigate the clinical significance of the inferior wall cartilage of the auditory meatus in surgical treatment of congenital first branchial cleft anomalies (CFBCAs) in children.Methods Twenty children diagnosed with CFBCAs who underwent surgery between December 2018 and June 2022 at our hospital were retrospectively analyzed and classified according to their Work lesion type. The guiding significance of the inferior wall cartilage in the surgical treatment of CFBCAs was summarized by investigating the adjacent relationships of the surgical lesions with the external auditory canal and facial nerve.Results Of the 20 patients, 16 were classified as Work type I and 4 as Work type II. The lesions were adjacent to the inferior wall cartilage of the auditory meatus in all children. Work type I lesions were located in the upper lateral aspect and were not adjacent to the facial nerve. Work type II lesions were located in the inferior-medial region of the facial nerve. The lesions were completely resected in all children. One patient experienced recurrence 3 months postoperatively because of a residual endochondral fistula. No patients developed facial paralysis or other complications.Conclusions The inferior wall cartilage of the auditory meatus may help to the identify the initial lesion of the CFBCAs and can be regarded as a guiding anatomical structure. These lesions can be completely resected. For resection of Work type II first branchial cleft lesions, the surgical incision can be narrower, and can be precisely positioned with the assistance of endoscope.
Abstract Context Paragangliomas located within the pericardium represent a rare yet challenging clinical situation. Objective The current analysis aimed to describe the clinical characteristics of cardiac paragangliomas, with emphasis on the diagnostic approach, genetic background, and multidisciplinary management. Methods Twenty-four patients diagnosed with cardiac paraganglioma (PGL) in Peking Union Medical College Hospital, Beijing, China, between 2003 and 2021 were identified. Clinical data was collected from medical record. Genetic screening and succinate dehydrogenase subunit B immunohistochemistry were performed in 22 patients. Results The median age at diagnosis was 38 years (range 11-51 years), 8 patients (33%) were females, and 4 (17%) had familial history. Hypertension and/or symptoms related to catecholamine secretion were present in 22 (92%) patients. Excess levels of catecholamines and/or metanephrines were detected in 22 (96%) of the 23 patients who have completed biochemical testing. Cardiac PGLs were localized with 131I-metaiodobenzylguanidine scintigraphy in 11/22 (50%), and 99mTc-hydrazinonicotinyl-tyr3-octreotide scintigraphy in 24/24 (100%) patients. Genetic testing identified germline SDHx mutations in 13/22 (59%) patients, while immunohistochemistry revealed succinate dehydrogenase (SDH) deficiency in tumors from 17/22 (77%) patients. All patients were managed by a multidisciplinary team through medical preparation, surgery, and follow-up. Twenty-three patients received surgical treatment and perioperative death occurred in 2 cases. Overall, 21 patients were alive at follow-up (median 7.0 years, range 0.6-18 years). Local recurrence or metastasis developed in 3 patients, all of whom had SDH-deficient tumors. Conclusion Cardiac PGLs can be diagnosed based on clinical manifestations, biochemical tests, and appropriate imaging studies. Genetic screening, multidisciplinary approach, and long-term follow-up are crucial in the management of this disease.

BACKGROUND:Sporadic cases of extranasopharyngeal angiofibroma in children, especially preschool children, have been reported in the literature.CASE SUMMARY:We present a case of extranasopharyngeal angiofibroma in a 4-year-old boy. The presenting symptoms, imaging findings, treatment, histological appearance, and follow-up data are described in detail. For this patient, we performed embolization on two occasions, and then, resected the tumor completely. During the treatment, the patient developed a soft-palate perforation due to aseptic necrosis. However, the healing ability was good, and the perforation healed spontaneously. We additionally reviewed all pediatric cases of extranasopharyngeal angiofibroma published up to 30 June 2020 in the PubMed, Baidu Scholar, Scopus, and Web of Science databases. We identified 45 pediatric patients [average (10.98 ± 4.86), boys 39 (86.7%)]. The highest proportion of cases occurred in adolescence [22 (48.9%)]. The top three sites of occurrence of extranasopharyngeal angiofibroma in children were the maxillary sinus, nasal septum, and inferior turbinate.CONCLUSION:Extranasopharyngeal angiofibromas can occur throughout childhood, and predominantly present with nasal obstruction and spontaneous rhinorrhagia.

Objective:To investigate the efficacy and safety of liraglutide combined with metformin in the treatment of overweight or obese patients with type 2 diabetes, and to analyze the factors influencing the response to liraglutide.Methods:Seventy-three overweight or obese patients with well-controlled type 2 diabetes on metformin were selected and treated with liraglutide at 1.8 mg/d in addition to metformin at 1500 mg/d for 48 weeks. Relevant data were collected before and after treatment, including blood glucose, glycosylated hemoglobin (HbA1c), fasting insulin, serum lipid, body weight, waist circumference, hip circumference, body mass index (BMI), homeostatic model assessment for β-cell function (HOMA-β) and homeostatic model assessment for insulin resistance (HOMA-IR). Changes in metabolic markers, incidence of side effects, weight loss efficacy and corresponding influencing factors were evaluated.Results:After 48 weeks of treatment, fasting blood glucose, 2-hour postprandial blood glucose, HbA1c, fasting insulin, HOMA-IR, blood lipid, waist circumference, hip circumference and BMI decreased significantly compared with baseline ( P < 0.05). The most common side effects were tolerable gastrointestinal adverse events. The average weight loss after the initial 4-week treatment was 3.99 kg, accounting for 48.8% of the total weight loss, and then the change displayed a more subdued trend during the remaining treatment period. After the 48-week treatment, 73.1% and 34.6% of the patients lost more than 5% and 10% of body weight, respectively. Absolute weight loss was positively correlated with baseline weight and weight loss within the initial 4-week treatment was an independent predictor of weight loss ≥ 5% at the 48th week. Conclusions:Liraglutide combined with metformin is safe and effective in the treatment of overweight or obese patients with type 2 diabetes mellitus. Weight loss is significant during the initial 4 weeks and the early response seems to be a predictor for better long-term effect on weight loss.
