Feasibility of Intensive Voice Therapy for Pediatric Vocal Fold Nodules Delivered via Telepractice: Pilot Study.

Purpose: The aim of this study is to assess the feasibility of an intensive voice therapy delivered via telepractice for pediatric vocal fold nodules (VFNs).

Method: Ten children with VFNs (mean age = 6 years, range = 5-8 years) were recruited in this study. Assessments including stroboscopic ratings, acoustic parameters, aerodynamic and auditory perceptual measures, and parent-reported Pediatric Voice Handicap Index were administered pretreatment and within 1 week post treatment.

Hearing loss prevalence and burden of disease in China: Findings from provincial-level analysis.

Background: Without timely and effective rehabilitation, hearing loss may profoundly affect human life quality. China has a large population of hearing-impaired individuals, which imposes a heavy health burden on society. Moreover, this population is projected to increase rapidly owing to China's aging society.

[Long-term auditory monitoring in children with Alport syndrome based on different degrees of renal injury].

To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted.

Animal study: Basic mechanism of vocal cord paralysis caused by button battery ingestion in children.

Purpose: Vocal cord paralysis has been reported as a common complication of button battery (BB) ingestion, and there is a need to confirm the mechanism of vocal cord paralysis for the development of a standardized treatment.

Methods: A new CR2032 BB and artificial saliva were placed in a fresh pig esophagus with the recurrent laryngeal nerve (RLN); the negative electrode faced the nerve in the experimental group, while the positive electrode faced the nerve in the control group. The pH values of the intra- and extraesophageal walls were measured simultaneously.

Vocal cord paralysis following lithium button battery ingestion in children.

This study reports on vocal cord paralysis caused by esophageal button battery (BB) ingestion in children. Medical records of children with vocal cord paralysis and esophageal BB ingestion treated at a tertiary referral institute between January 2016 and March 2020 were reviewed. Five patients aged 9-58 months were identified; three were male.

Salicylate increased ascorbic acid levels and neuronal activity in the rat auditory cortex.

Importance: Clinical observations have implied a central origin for tinnitus and potential therapeutic effects of ascorbic acid (AA); however, the detailed mechanisms remain undetermined.

Objective: To investigate changes in the AA levels and neural activity in the auditory cortex (AC) during salicylate-induced tinnitus.

Methods: Rats were randomly divided into 3 groups: (1) saline group, which received an intraperitoneal saline injection; (2) SS group, which received an intraperitoneal sodium salicylate (SS) injection (350 mg/kg); and (3) SS+Lido group, which received an intraperitoneal SS injection (350 mg/kg) and lidocaine delivered to the AC by microdialysis.

[39 cases of malignant tumors originated from external and middle ear].

Objective: To describe our experience in the clinical manifestation and treatment of malignant tumors of the external and middle ear.

Method: The study reviewed 39 patients between 1994-2011 in our hospital, including 15 pinna tumors, 18 external canal tumors and 6 middle ear tumors. 23 males and 16 females were enrolled in this study.

[Eustachian tube dysfunction misdiagnosed: a case report].

The patient has complained of fullness in her right ear since she took a flight 5 years ago. Pure tone audiometry indicated normal hearing threshold and acoustic immitance proved type A tympanogram in both ears. She visited different doctors over and over again, with every doctor diagnosed her with psychogenic ear fullness.

[The correlation of serum specific IgE detection and skin prick test in allergic rhinitis].

Objective: To investigate the correlation between serum specific immunoglobin E(sIgE) and skin prick test(SPT) and their differences of the positive rate.

Method: One hundred and nine patients with allergic rhinitis were detected the serum slgE. The patients had positive symptoms and signs, positive SPT results with at least one allergen.

[Analysis of misdiagnosis and differential diagnosis of infectious mononucleosis in adults].

Objective: To explore the clinical characteristics of infectious mononucleosis (IM) in adults.

Method: Medical records of 50 adult IM patients admitted in hospital were analyzed retrospectively.

Result: Diagnosis delayed group contained 16 patients (32% of total patients) and was significantly different from the diagnosis in-time group in typical symptoms, signs and laboratory findings of IM.
