Disease-Related Knowledge, Stress, and Quality of Life of Parental Caregivers of Children with Cleft Lip and Palate in a Selected Hospital in Ho Chi Minh City, Vietnam.

Introduction: Cleft lip and palate (CLP) is one of the most common congenital anomalies worldwide, affecting approximately 2,000 children annually in Vietnam. Parental caregivers, particularly mothers, face considerable challenges in managing complex treatment pathways and addressing their children's multifaceted needs. This often leads to increased stress and decline in the quality of life (QoL).

IGF-1 Mediated Neuroprotective Effects of Olfactory-Derived Mesenchymal Stem Cells on Auditory Hair Cells.

Importance: Mesenchymal stem cells (MSCs) have the capability of providing ongoing paracrine support to degenerating tissues. Since MSCs can be extracted from a broad range of tissues, their specific surface marker profiles and growth factor secretions can be different. We hypothesized that MSCs derived from different sources might also have different neuroprotective potential.

How standardised are antibiotic regimens in otologic surgery?

Background: Within otologic surgery, a paucity of well-controlled studies assessing the use of systemic antibiotic to reduce surgical site infections exists. Moreover, discrepancies in wound classification of procedures challenge consensus in antimicrobial prescribing patterns. We sought to compare surgeons from two different health systems to examine how surgeons' prescribing habits compared to practice guidelines for numerous otologic procedures.

Study Design: Retrospective study of provincial CI Program database.

Setting: Academic hospital.

The feasibility and safety of eustachian tube dilation with a standard endovascular balloon: a clinical pilot study.

Background: Obstructive eustachian tube dysfunction is a common pathology, generally accepted as the underlying cause for chronic ear diseases. Eustachian tube dilation has shown promising results in randomized controlled trials, but is a costly procedure. The aim of the current study was to assess the feasibility of transnasal balloon dilatation of the eustachian tube with an endovascular balloon in the context of ease of use, maneuverability, and safety.

Neural responses to naturalistic audiovisual speech are related to listening demand in cochlear implant users.

There is a weak relationship between clinical and self-reported speech perception outcomes in cochlear implant (CI) listeners. Such poor correspondence may be due to differences in clinical and "real-world" listening environments and stimuli. Speech in the real world is often accompanied by visual cues, background environmental noise, and is generally in a conversational context, all factors that could affect listening demand.

Manipulating the blood labyrinth barrier with mannitol to prevent cisplatin-induced hearing loss.

Cisplatin, a chemotherapeutic medication, remains in the cochlea indefinitely, causing permanent hearing loss. Mannitol, a diuretic medication, has been shown to increase the permeability of the blood labyrinth barrier (BLB). We hypothesize that mannitol increases the permeability of the BLB and therefore increases the rate of entry and egression of cisplatin and entry of otoprotective agents.

Magnetic Targeting of Gadolinium Contrast to Enhance MRI of the Inner Ear in Endolymphatic Hydrops.

Objectives: 1. Determine the feasibility and efficiency of local magnetic targeting delivery of gadolinium (Gad) contrast to the inner ear in rodents. 2.

The Feasibility of Eustachian Tube Dilation With a Standard Endovascular Balloon: A Comparative Cadaver Study.

Background: Balloon dilation of the eustachian tube is a new therapeutic option for eustachian tube dysfunction. One of the limiting factors of wider adoption of this technique in many parts of the world is the high cost of the devices, in spite of regulatory approval of safety.

Objective: Evaluate the performance and usability of standard less-expensive endovascular balloons for eustachian tube dilation in comparison to an approved device in a preclinical study.

Pain Management Following Otological Surgery: A Prospective Study of Different Strategies.

Objectives: The aim of this study was to prospectively assess pain and associated analgesic consumption after otological surgery comparing two prescription patterns.

Study Design: A prospective nonrandomized consecutive cohort study.

Methods: 125 adult patients undergoing ambulatory otologic surgery-cochlear implantation and endaural middle ear surgery, were assigned (according to surgeon's preference) and prospectively studied in two arms: 1) acetaminophen 500 mg + ibuprofen 400 mg; 2) acetaminophen 500 mg + codeine 30 mg.

Local magnetic delivery of adeno-associated virus AAV2(quad Y-F)-mediated BDNF gene therapy restores hearing after noise injury.

Moderate noise exposure may cause acute loss of cochlear synapses without affecting the cochlear hair cells and hearing threshold; thus, it remains "hidden" to standard clinical tests. This cochlear synaptopathy is one of the main pathologies of noise-induced hearing loss (NIHL). There is no effective treatment for NIHL, mainly because of the lack of a proper drug-delivery technique.

Is otologic surgery contributing to the opioid epidemic?

Background: The opioid epidemic is a significant public health crisis challenging the lives of North Americans. Interestingly, this problem does not exist to the same extent in Europe. Surgeons play a significant role in prescribing opioids, especially in the context of post-operative pain management.

Monitoring photosynthetic microorganism activity with an electrolyte-gated organic field effect transistor.

Among organic thin film transistors (OTFTs), Organic Electrochemical Transistors (OECTs) have been extensively used for cell monitoring while Electrolyte-Gated Organic Field-Effect Transistors (EGOFETs) have never been described for that kind of application. However, EGOFETs are well adapted for this use because, as well as OECTs, they can operate directly in aqueous solutions such as cells culture media, but they offer much a higher on/off ratio which could lead to better sensitivity. As a proof of concept, we propose herein to monitor the photosynthetic activity of a cyanobacterium (Anabaena flos-aquae) contained within an EGOFET's electrolyte.

Clinical Characteristics and Histopathology of Idiopathic Epiretinal Membrane in Vietnam.

Background: Idiopathic epiretinal membrane (iERM) is an avascular proliferation of different types of cells between the posterior vitreous cortex and the internal limiting membrane. That causes visual impairment including blurry, distortion, scotoma. Many studies of iERM were done to describe the clinical characteristics and investigate the histopathology of this disease.

Cone beam CT for perioperative imaging in hearing preservation Cochlear implantation - a human cadaveric study.

Background: Knowledge of the cochlear implant array's precise position is important because of the correlation between electrode position and speech understanding. Several groups have provided recent image processing evidence to determine scalar translocation, angular insertion depth, and cochlear duct length (CDL); all of which are being used for patient-specific programming. Cone beam computed tomography (CBCT) is increasingly used in otology due to its superior resolution and low radiation dose.

Vestibular Neuritis: Recent Advances in Etiology, Diagnostic Evaluation, and Treatment.

Purpose of Chapter: This chapter highlights the recent advances in etiology, diagnostic evaluation, and management of vestibular neuritis (VN). Recent Findings: The viral hypothesis has been strengthened with new evidence as the main etiology of VN. Recent evidence indicates that bedside oculomotor findings play a critical role in differentiating VN from stroke.

Mannitol and the blood-labyrinth barrier.

Background: Characterization of the blood labyrinth barrier (BLB) is extremely important to determine whether the BLB can be manipulated pharmacologically. However, experiments to investigate the BLB are technically difficult to perform. In this report, we demonstrated a unique method of controlling the BLB, and established the pharmacokinetics of gentamicin in perilymph, cerebrospinal fluid (CSF) and blood with and without mannitol.

GABAergic Interneuron Differentiation in the Basal Forebrain Is Mediated through Direct Regulation of Glutamic Acid Decarboxylase Isoforms by Homeobox Transcription Factors.

GABA is the key inhibitory neurotransmitter in the cortex but regulation of its synthesis during forebrain development is poorly understood. In the telencephalon, members of the distal-less () homeobox gene family are expressed in, and regulate the development of, the basal ganglia primodia from which many GABAergic neurons originate and migrate to other forebrain regions. The double knock-out mice die at birth with abnormal cortical development, including loss of tangential migration of GABAergic inhibitory interneurons to the neocortex (Anderson et al.

Current insights in noise-induced hearing loss: a literature review of the underlying mechanism, pathophysiology, asymmetry, and management options.

Background: Noise-induced hearing loss is one of the most common forms of sensorineural hearing loss, is a major health problem, is largely preventable and is probably more widespread than revealed by conventional pure tone threshold testing. Noise-induced damage to the cochlea is traditionally considered to be associated with symmetrical mild to moderate hearing loss with associated tinnitus; however, there is a significant number of patients with asymmetrical thresholds and, depending on the exposure, severe to profound hearing loss as well.

Main Body: Recent epidemiology and animal studies have provided further insight into the pathophysiology, clinical findings, social and economic impacts of noise-induced hearing loss.
