Objective:To explore the clinical characteristics and treatment methods of middle ear cholesteatoma with intracranial and extracranial complications as the first diagnosis. Methods:A total of 244 patients were initially diagnosed with intracranial and/or extracranial complications associated with middle ear cholesteatoma at the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2022, and medical records were collected and retrospectively analyzed. Results:Among 244 patients with intracranial and extracranial complications of middle ear cholesteatoma, 203 cases had one complication, 34 cases had 2 complications, and 7 cases had 3 or more complications. One hundred and eighty-six cases presented labyrinthitis, 41 cases had peripheral facial paralysis, 27 cases had periauricular abscess, 12 cases had meningitis, 10 cases had brain abscess, 7 cases had sigmoid sinus lesions, 6 cases had epidural abscess, and 4 cases demonstrated hydrocephalus. Conclusion:The destructive nature of middle ear cholesteatoma can lead to intracranial and extracranial complications. The incidence rate of extracranial complications is highest for labyrinthitis. Patients with otitis media who complained dizziness should raise clinical suspicion for potential labyrinthitis. The second most prevalent extracranial complication is peripheral facial paralysis, and early facial nerve decompression surgery is critical for better recovery of facial paralysis symptoms. Brain abscess is the most common intracranial complications, which has the highest fatality rate. Clinicians should be alert to otogenic brain abscess. Otolaryngology and neurosurgery teams should cooperate and evaluate patients' middle ear lesions and brain abscess, and jointly develop personalized treatment plans.

Objective:X-linked non-syndromic hearing loss is an extremely rare type of hearing impairment. This study conducted a phenotypic and genetic analysis of a family with X-linked dominant inheritance to explore the causes of hearing loss. Methods:Clinical data were collected from a patient with non-syndromic hearing loss who visited the Otorhinolaryngology Department of the First Affiliated Hospital of Zhengzhou University in June 2023. Phenotypic and genetic analyses were performed on family members, including audiometric tests, whole-exome sequencing, and PCR-Sanger sequencing verification. Audiological assessments comprised pure-tone audiometry, impedance audiometry, auditory brainstem response, and otoacoustic emission tests. Results:The affected individuals in this pedigree have X-linked dominant non-syndromic deafness caused by mutations in the SMPX gene. The proband, along with their mother and maternal grandmother, exhibit varying degrees of sensorineural hearing loss. Whole-exome sequencing revealed a novel pathogenic variant, NM_014332.3: c. 133-2A>C, in the SMPX gene in the proband. Sanger sequencing confirmed that the proband, proband's mother, and grandmother all carried this pathogenic variant. Conclusion:This study reports a novel pathogenic variant in the SMPX gene, providing additional medical evidence for the diagnosis and treatment of X-linked dominant inherited non-syndromic hearing loss. It enriches the mutation spectrum of the SMPX gene.

Objective:To understand the awareness of influenza and influenza vaccine, influenza incidence, influenza vaccination status and intention and related factors in primary and secondary school teachers.Methods:Cross-sectional study design and stratified random sampling method were used to select 5 teachers from each of 51 primary schools and 40 middle schools in a district of Beijing from April 17 to 21, 2024. A questionnaire survey was conducted in the selected teachers with an estimated sample size of 1 040. The survey collected the information about their demographic characteristics, awareness of influenza and influenza vaccine, influenza incidence, influenza vaccination status and intention. Multivariate logistic regression model was used to analyze the factors related to influenza vaccination status and intention.Results:In the 975 primary and secondary school teachers, the awareness of susceptibility and severity of influenza and the benefits of influenza vaccination were high. In terms of safety of influenza vaccine, 48.00% (468/975) of the teachers believed that adverse reaction would occur after the vaccination. Influenza like illness occurred in 41.13% (401/975) of the teachers during 2023-2024, and in these teachers, 40.15% (161/401) asked for leave from work due to illness, 40.90% (164/401) sought medical care and 32.93% (54/164) were influenza virus positive. In the 975 teachers, 13.95% (136/975) were vaccinated against influenza during 2023-2024 and 34.46% (336/975) were willing to be vaccinated against influenza during 2024-2025. Multivariate logistic regression analysis showed that being teacher in charge of a class (a OR=1.58, 95% CI: 1.06-2.35), believing that influenza vaccination could effectively prevent influenza (a OR=1.99, 95% CI: 1.05-3.80), believing that teachers' vaccination could improve students' willingness to be vaccinated (a OR=1.98, 95% CI: 1.12-3.50) were the positive factors for teachers' vaccination, and worrying about adverse reactions after the vaccination (a OR=0.52, 95% CI: 0.34-0.80) was the negative factor. Doctors' recommendation (a OR=2.62, 95% CI: 1.41-4.86) and free influenza vaccination (a OR=10.26, 95% CI: 5.17-20.39) were positively correlated with teachers' intention to influenza vaccination. Conclusions:Primary and secondary school teachers in a district of Beijing had high awareness of influenza and influenza vaccine, but their awareness of influenza vaccine safety should be improved. The incidence of influenza-related infection was high in the primary and secondary school teachers. The influenza vaccination rate was low and the willingness to receive influenza vaccination in following year was not strong. For the better prevention and control of influenza in schools, it is necessary to strengthen the health education in primary and secondary school teachers to improve their awareness of influenza vaccine safety and vaccination rate.

Objective To compare the clinical effect of tympanoplasty with and without eustachian tube bal-loon dilatation(ETBD)in the treatment of adhesive otitis media(AOM).Methods A total of 43 patients with AOM and eustachian tube dysfunction(ETD)were retrospectively analyzed,and were divided into the experimental group(n=22)who underwent tympanoplasty combined with ETBD and the control group(n=21)who underwent tympanoplasty alone.The changes of average air conduction hearing thresholds,pure-tone air-bone gap(ABG)and eustachian tube score(ETS)were compared between the two groups before and after surgery at 6 months and 2 years.Results There were no significant differences between the experimental group and the control group in air conduction hearing thresholds,ABG and ETS before operation(P＞0.05).Comparison within both the two groups after operation:air conduction hearing thresholds and ABG in both groups were significantly reduced(P＜0.05),and ETS in the experimental group was significantly higher than that before surgery(P＜0.05).Comparison be-tween two groups after operation:there were no statistically significant differences in the air conduction hearing thresholds and ABG at 6 months after surgery(P＞0.05),while there was statistically significant difference in ETS(P＜0.05).At 2 years,there were statistically significant differences in the air conduction hearing thresholds,ABG and ETS between the two groups(P＜0.05)with the experimental group showing better outcomes.Conclusion Tympanoplasty can significantly improve the postoperative hearing of AOM.Tympanoplasty combined with ETBD not only effectively improves the eustachian tube function,but also shows better long-term follow-up hearing im-provement,making it an effective treatment for AOM patients.

Objective:To study the efficacy and safety of anlotinib in the treatment of advanced radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC) and the effect of anlotinib on iodine uptake of lesions.Methods:A retrospective analysis was performed on 23 patients (10 males and 13 females, age (59.1±8.7) years) with advanced RAIR-DTC who were treated with anlotinib in Liaocheng Hospital Affiliated to Shandong First Medical University between January 2019 and February 2023 and met the enrollment criteria. Thyroid function, serum thyroglobulin (Tg) and Tg antibody (TgAb) were determined every 6 weeks during the treatment with anlotinib, and maximum diameter of target lesion (TL) was monitored by CT every 12 weeks, in order to evaluate the therapeutic efficacy, and treatment-related adverse reactions were observed. Diagnostic 131I whole body scan (Dx-WBS) was performed in some patients to evaluate the changes in iodine uptake of lesions after anlotinib treatment. In this study, the posttreatment changes of patients within 24 weeks during the treatment were analyzed. The maximum diameter of TL and Tg at different time points were compared by Friedman test, and were further compared in pairs with P values corrected by Bonferroni method. Results:After 24 weeks of treatment with anlotinib, 8 of 23 patients achieved partial response, 15 had stable disease, and no patients achieved complete response. Serum Tg levels at 6, 12, 18, 24 weeks after anlotinib treatment were 189.5(85.0, 483.3), 127.7(52.4, 319.8), 82.0(40.2, 213.5) and 80.1(39.9, 205.0) μg/L, all of which were lower than the baseline level of Tg (384.5(210.9, 1 605.0) μg/L; χ2 values: 4.23-7.86, all P<0.001). Tg level at 18 weeks after treatment was statistically different from that at 12 weeks after treatment ( χ2 =3.06, P<0.001), but was not statistically different from that at 24 weeks after treatment ( χ2 =12.57, P=0.059). The maximum TL diameters of lung and cervical lymph nodes were significantly reduced at week 12 and 24 of anlotinib treatment compared with baseline ( χ2 values: 14.76-31.12, all P<0.001), while there was no significant difference in TL maximum diameter at 12 and 24 weeks of treatment ( χ2 values: 5.65, 9.02, P values: 0.314, 0.070). Common adverse reactions included hypertension, hand-foot syndrome, hyperacylglyceremia and proteinuria. No adverse reactions above grade 4 or death related to adverse reactions occurred. Dx-WBS evaluation was performed in 7 patients after anlotinib treatment, and no change in iodine uptake was found. Conclusions:Anlotinib has a clear effect on advanced RAIR-DTC with less adverse reactions. The efficacy of anlotinib reaches the strongest at around 12-18 weeks and becomes stable at 24 weeks. No effect of anlotinib on inducing redifferentiation of RAIR-DTC cells and enhancing iodine uptake is found.

Objective:To explore the risk factors of osteosarcopenia in maintenance hemodialysis patients, construct a diagnostic nomogram model and verify the effect.Methods:Usingthe convenient sampling method, a total of 697 patients who underwent regular hemodialysis in six hospitals in Shanghai from July 2020 to April 2021 were selected as the modeling set, and 132 patients who underwent regular hemodialysis in Tongji Hospital in Shanghai in November 2020 were selected as the validation set. General information, laboratory indicators, human parameters, physical functions, nutritional status, physical activity, cognitive function, and depression were collected. Logistic regression was used to analyze the risk factors of osteosarcopenia in maintenance hemodialysis patients and to construct a nomogram model. The effect of the model was evaluated by the area under the receiver operating characteristic curve, calibration curve, and decision curve.Results:A total of 697 maintenance hemodialysis patients were included in the modeling set, including 171 patients with osteosarcopenia, with an incidence rate of 24.53% (171/697). The results of the binomial logistic regression analysis showed that age, body mass index, physical activity intensity, and Charlson Comorbidity Index (CCI) were the influencing factors for the occurrence of osteosarcopenia in maintenance hemodialysis patients ( P<0.05). The area under the receiver operating characteristic curve in the modeling set, ten-fold cross-validation, and validation set were 0.835, 0.827, and 0.851, respectively. The calibration curves of the modeling and validation sets fitted well. The decision curve showed that the clinical utility of the nomogram was good. Conclusions:Maintenance hemodialysis patients are prone to osteosarcopenia. Old age, low body mass index, high Charlson Comorbidity Index, and low-intensity physical activity are risk factors for osteosarcopenia in maintenance hemodialysis patients. A nomogramdiagnostic model based on the above-mentioned influencing factors can help medical staff identify high-risk populations early and develop prevention and treatment measures.

Objective To investigate the application value of multiple audiological testing methods in the audi-ological diagnosis of children with no response at maximum output intensity of auditory brainstem response(ABR).Methods We retrospectively studied the clinical data of 69 cases(138 ears)of children with no ABR response with maximum intensity,aged 42 days to 5 years old,with an average of 1 year and 6 months.The tympanogram showed type-A or positive single peak,and acoustic reflex was absent.Imaging examination showed no malformation of the inner ear.All 69 children underwent ABR,cochlear microphonic potential(CM),distortion product otoacoustic e-missions(DPOAE),and auditory steady-state response(ASSR)tests.Results Among 69 cases(138 ears),8 ca-ses(11.59％)recorded CM in 16 ears,of which 10 ears(7.25％)recorded DPOAE.The ASSR response thresh-olds at 0.5,1,2,and 4 kHz were 83.2±13.1,82.9±13.0,75.3±12.4,and 63.1±9.1 dB nHL,respectively.Combined with other examination results,these subjects were diagnosed with auditory neuropathy.The CM and DPOAE responses of the remaining 61 cases(122 ears)were absent,and the extraction rates of ASSR at 0.5,1,2,and 4 kHz were 82.3％,81.9％,76.9％,and 60.2％,respectively.Among them,20 ears of ASSR were absent at all frequencies,and 102 ears had responses in at least one frequency.The response thresholds of ASSR at 0.5,1,2,and 4 kHz were 93.2±6.1,99.8±7.0,105.4±5.4,108.2±9.8 dB nHL,respectively.These subjects were diagnosed with profound sensorineural hearing loss.Conclusion For children with no ABR response at maximum output intensity,while CM and/or DPOAE responses are present and ASSR frequency response thresholds are low-er than those with sensorineural hearing loss are helpful in the diagnosis of auditory neuropathy.Neither CM nor DPOAE response is helpful in the diagnosis of profound sensorineural hearing loss,and ASSR testing is helpful in e-valuating residual hearing.
