Objective To investigate the development of auditory and speech skills and the safety and stability among the prelingually deaf children with Nurotron Venus cochlear implants.Methods A total of 78 cochlear implant subjects were recruited from the first of affiliated hospital of Zhengzhou university.They were divided into 5 groups according to the ages at the time of implantation: group A(between 13 and 24 months), group B(between 25 and 36 months),group C(between 37 and 48 months),group D(between 49 and 72 months),group E(between 73 and 96 months).Children were evaluated by IT-MAIS(group A and B) and MAIS(group C,D and E) before the surgery and 1 month,3 months,6 months, and 12 months after surgery.All children were evaluated by MUSS questionnaires 1 months, 3 months,6 months,and 12 months after surgery.Post-operative cochlear radiographs determine the position of the CIs.The complications and usage of The CIs were followed up.Results The auditory and speech ability of children with CIs improved constantly.The auditory and speech of different groups were statistically significant.All the surgeries of 78 cases Nurotron-Venus cochlear implants were successful.Post-operative cochlear radiographs showed electrodes in the normal position.2 cases had processor failures.The remaining CIs were implanted completely.Conclusion Within 1 year, the ability of auditory and speech improved gradually.The scores of auditory and speech about the small age groups are lower than older children in the early days.There is no influence on the audition in 12 months.Small children's scores of speech are lower than older children in 12 months.The better ability to integrate auditory information is , the better the ability to speak is.The Nurotron CIs work safety and effectively.

Objective To discuss the clinical characteristic of middle ear malformation with cholesteatoma.Methods From September,2011 to November,2016,23 cases of middle ear malformation with cholesteatoma were collected.Their symptoms,ENT examination,temporal bone high resolution computed tomography (HRCT) and intraoperative findings were analyzed.Results All 23 patients had hearing loss.90.0％ patients had ear discharge and tinnitus.86.96％ patients had perforation in pars flaccida of tympanic membrane.95.7％ patients had poor mastoid gasification.73.9％ patients had undeveloped or dysplastic tympanic antrum.100％ patients had destruction of the ossicular chain.56.5％ patients had malformation of the ossicular chain.52.2％ patients had exposed facial nerve.30.4％ patients had hyperplasia of the attic bone.Conclusion The symptoms and physical examinations of middle ear malformation with cholesteatoma are the same as middle ear cholesteatoma.Poor mastoid gasification can usually be detected on temporal bone HRCT.The most common malformation is dysplastic tympanic antrum,followed by malformation of the ossicular chain,exposed facial nerve and hyperplasia of the attic bone.Temporal bone HRCT can indicate the malformation and destruction quite well.

BACKGROUND: Currently, the morphologic characteristics of the torn discoid lateral meniscus remain unclear, andmorphological indexes used to evaluate the discoid lateral meniscus tears still need to be explored. OBJECTIVE: To discuss the specificity and sensitivity of discoid lateral meniscal tears in children using morphological indexes. METHODS: Seventy-three patients (seventy-six knees) with torn discoid lateral meniscus underwentarthroscopy and MRI data of knee examinations were retrospectively reviewed. All MR images were double-blinded, independently, retrospectively analyzed by attending radiologist (doctor A) and sports physician (doctor B). The following morphological signs of discoid lateral meniscus, such as a internal displaced free edge sign, a hypertrophic free edge sign and a hypertrophied-horn sign, were selected to evaluate the discoid lateral meniscus tears. The likelihood of the discoid lateral meniscus tears was analyzed on basis of arthroscopic findings constituted the gold standard. Sensitivity, specificity and accuracy of MRI diagnosis of the discoid lateral meniscus tears by two physicians were calculated, and the consistency of diagnosis results by two physicians was evaluated using the Kappa statistics.RESULTS AND CONCLUSION: (1) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscustears by internal displaced free edge sign for doctor A were 19%, 94% and 53%, respectively, and for doctor B were 21%, 97% and 55%. (2) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by hypertrophic free edge sign for doctor A were 52%, 100% and 74%, respectively, and for doctor B were 57%, 97% and 75%. (3) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by hypertrophied-horn sign for doctor A were 26%, 97% and 58%, respectively, and for doctor B were 24%, 100% and 58%. (4) The sensitivity, specificity and accuracy in the diagnosis of discoid lateral meniscus tears by binding morphological index for doctor A were 86%, 91% and 87%, respectively, and for doctor B were 88%, 94% and 91%. (5) The Kappa statistics for discoid lateral meniscus tears respectively demonstrated a good inter-observer agreement (K > 0.75, P < 0.001). (6) These findings suggest that single morphological index used to evaluate the discoid lateral meniscus tears shows a good specificity, but which also shows a low sensitivity, while a binding morphological index can significantly improve the diagnostic sensitivity. Morphological characteristics may be reliable indexes to evaluate the discoid lateral meniscal tears in children.

BACKGROUND:Currently, the morphologic changes of the discoid lateral meniscus (DLM) remain unclear, and morphological indexes used to evaluate the injuries of DLM stil need to be explored. OBJECTIVE:To compare the MR imaging difference between symptomatic and asymptomatic DLM in adults, and to select reliablemorphologicalparametersfor assessing DLM. METHODS:A total of 36 patients (36 knees) with a symptomatic DLM (study group)and 34 patients (34 knees) with an asymptomatic DLM (control group) were included in this study. GE Healthcare Centricity RIS/PACKS System was used to measure the primary morphological parameters of two patients with DLM on coronal MR imaging. Intergroup comparison was performed with the Wilcoxon test. RESULTS AND CONCLUSION:On the coronal MR imaging, the width of the body portion and height of the free edge of the DLM was significantly increased in the study group compared with the control group (P< 0.001), while the height of the peripheral portion which connects with the capsule of the DLM was significantly decreased in the study group compared with the control group (P= 0.002). The heightof the middle of the DLM and the width of the lateral femoral condyle showed no significant differences between the both groups (P> 0.05). The width ratio of the body of the DLM to the lateral femoral condyle and the height ratio of height of the free edge to the middle of the DLM were significantly increased in thestudy group compared with the control group (P< 0.001), while the height ratio of the peripheral portion to the middle for the DLM was significantly decreased compared with the control group (P< 0.001). These findings suggest that compared with asymptomatic discoid lateral meniscus, the width of the body portion and the height of the free edge for the DLM are increased;however,the height of the peripheral portion which connects with the capsule of the DLM is decreased. The width ratio of the body portion of the DLM to the lateral femoral condyle and the height ratio of the free edge to the middle for the DLM may be reliable morphological parameters for the assessment of the DLM in adults.

Objective To evaluate the effect of intensive hypertension management model for patients with uncontrolled blood pressure in community.Methods Three hundred and seven hypertensive patients,whose blood pressure was not controlled with administration of two or more kinds of antihypertensive drugs,entered in the intensive management program from May 2015 to December 2017.Using calcium channel blockers,angiotensin converting enzyme inhibitors or angiotensin receptor blockers and diuretic as the primary scheme,the medication was adjusted by general practitioners under the guidance of specialists in tertiary hospitals.The "seamless" two-way referral between community and tertiary hospitals was implemented,and the blood pressure control,medication and adverse effects were analyzed.Results Among 307 patients,157 were males (51.1％) and the mean age was (65.0±8.6) years.There were 246 (80.0％)patients with moderate and severe hypertension 44 (14.3％) patients complicated with diabetes,and 63(20.5％) patients having comorbidities,and the patients with high risk or extremely high-risk accounted for 85.0％ (261/307).Through (3.97± 1.21) months (1-6 months) intensive management,systolic blood pressure decreased from (167.56±16.73)mmHg(1 mmHg=0.133 kPa) in the baseline to (132.79±11.24)mmHg (t=33.34,P＜0.01),and diastolic blood pressure from (95.34± 12.59) mmHg to(79.11 ±7.85) mmHg (t=23.67,P＜0.01),blood pressure control rate was 75.6％(232/307).No serious adverse reactions occurred.During the period 42 patients were referral to hospital through green channel with a referral rate of 13.7％,and six patients were diagnosed as secondary hypertension.Angiotensin receptor antagonists and calcium antagonists were the main antihypertensive drugs.After intensive management patients taking three or more antihypertensive drugs increased by 158 and those taking diuretics increased by 116.Conclusions The intensive management model is effective in patients with uncontrolled blood pressure in community.Early use of C+A,A+D,and A+C+D treatment schemes for uncontrolled patients in the community can improve the rate of reaching the target and is safe.

OBJECTIVE: To explore the genetic basis for four Chinese pedigrees affected with Waardenburg syndrome (WS). METHODS: Four WS probands and their pedigree members who had presented at the First Affiliated Hospital of Zhengzhou University between July 2021 and March 2022 were selected as the study subjects. Proband 1, a 2-year-and-11-month female, had blurred speech for over 2 years. Proband 2, a 10-year-old female, had bilateral hearing loss for 8 years. Proband 3, a 28-year-old male, had right side hearing loss for over 10 years. Proband 4, a 2-year-old male, had left side hearing loss for one year. Clinical data of the four probands and their pedigree members were collected, and auxiliary examinations were carried out. Genomic DNA was extracted from peripheral blood samples and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing. RESULTS: Proband 1, with profound bilateral sensorineural hearing loss, blue iris and dystopia canthorum, was found to have harbored a heterozygous c.667C>T (p.Arg223Ter) nonsense variant of the PAX3 gene, which was inherited from her father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type I. Proband 2, with moderate sensorineural hearing loss on the right side and severe sensorineural hearing loss on the left side, has harbored a heterozygous frameshifting c.1018_1022del (p.Val340SerfsTer60) variant of the SOX10 gene. Neither of her parents has harbored the same variant. Based on the ACMG guidelines, it was classified as pathogenic (PVS1+PM2_Supporting+PP4+PM6), and the proband was diagnosed with WS type II. Proband 3, with profound sensorineural hearing loss on the right side, has harbored a heterozygous c.23delC (p.Ser8TrpfsTer5) frameshifting variant of the SOX10 gene. Based on the ACMG guidelines, it was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type II. Proband 4, with profound sensorineural hearing loss on the left side, has harbored a heterozygous c.7G>T (p.Glu3Ter) nonsense variant of the MITF gene which was inherited from his mother. Based on the ACMG guidelines, the variant was classified as pathogenic (PVS1+PM2_Supporting+PP4), and the proband was diagnosed with WS type II. CONCLUSION By genetic testing, the four probands were all diagnosed with WS. Above finding has facilitated molecular diagnosis and genetic counseling for their pedigrees.

Objective: To discuss the possible reasons for cerebrospinal fluid (CSF) gusher in cochlear implantation (CI) with inner ear abnormality. Method: A retrospective analysis was performed on 340 cases who underwent CI from January 2013 to December 2016 in Division of Otology, Otorhinolaryngology Hospital, the First Affiliated Hospital of Zhengzhou University. Among them, 96 cases had inner ear abnormalities. Imaging examinations were performed on these patients, and classification of inner ear malformation was done according to the results. Results: Among the cases with inner ear abnormality, 9.4% (9/96) suffered from CSF gusher during CI. The inner ear abnormalities were found to be as follows: 3 cases had incomplete partition type Ⅰ; 1 case had incomplete partition type Ⅰ with semicircular canal dysplasia; 1 case had common cavity deformity; 1 case had enlarged vestibular aqueducts and common cavity deformity; 2 cases had Mondini deformity. All of these cases had bony defect in the fundus of the internal acoustic meatus observed on CT scans. Another case was type 1 cochlear aqueduct with round window aplasia. Conclusions Defects in the modiolus or fundus of the internal acoustic meatus is the main reason for CSF gusher during CI. A patent cochlear aqueduct is another possible reason.

Objective: To discuss the prediction of round window(RW) visibility in cochlear implantation(CI) with temporal bone high resolution computed tomography(HRCT). Methods: From January 2013 to January 2017, 130 cases underwent both HRCT and CI in our hospital were analyzed. The distance from facial nerve to posterior canal wall(FWD), the angle between facial nerve and inner margin of round window(FRA), and the angle between facial nerve and tympanic anulus to inner margin of round window(FRAA) were detected at the level of round window on axial temporal bone HRCT. A line parallel to the posterior wall of ear canal was drawn from the anterior wall of facial nerve at the level of round window on axial temporal bone HRCT and its relationship with round window was detected (facial-round window line, FRL): type0-posterior to the round window, type1-between the round window, type2-anterior to the round window. Their(FWD, FRA, FRAA, FRL) relationships with intra-operative round window visibility were analyzed by SPSS 17.0 software. Results: FWD(F=18.76, P=0.00), FRA(F=34.57, P=0.00), FRAA (F=14.24, P=0.00) could affect the intra-operative RW visibility significantly. RW could be exposed completely during CI when preoperative HRCT showing type0 FRL. RW might be partly exposed and not exposed when preoperative HRCT showing type1 and type2 FRL respectively. Conclusion FWD, FRA, FRAA and FRL of temporal bone HRCT can predict intra-operative round window visibility effectively in CI surgery.
