Summary
Cochlear implantation (CI) offers excellent speech perception outcomes for patients with large vestibular aqueduct syndrome (LVAS). Early CI intervention is recommended when scores drop to 85% for optimal results.
Area of Science:
- Audiology
- Otolaryngology
- Neurosurgery
Background:
- Large vestibular aqueduct syndrome (LVAS) is a condition affecting hearing.
- Cochlear implantation (CI) is a surgical treatment for hearing loss.
Purpose of the Study:
- To evaluate postoperative speech perception in patients with LVAS who underwent cochlear implantation.
- To determine the optimal timing for CI in LVAS patients.
Main Methods:
- Retrospective analysis of the Sydney Cochlear Implant Centre (SCIC) database and medical records (1994-2015).
- Inclusion criteria: LVAS diagnosis, CI, and speech perception outcomes ≥12 months post-implantation.
- Outcome measure: Postoperative speech perception scores (BKB, CUNY, CNC).
Main Results:
- 176 patients with LVAS received CI.
- Speech perception data (BKB scores) available for 97 patients.
- Median postoperative BKB score was 93% (IQR: 85%-98%), indicating excellent outcomes.
Conclusions:
- Cochlear implantation is highly effective for LVAS patients.
- CI should be considered when Bamford-Kowal Bench (BKB) scores reach 85%.
- Early CI in LVAS patients leads to stable hearing and superior speech perception.

01:29The Vestibular System
43.5K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

02:24Predicting Reaction Outcomes
10.3K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

01:11Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

522
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

868
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
