Summary
Developing otoprotective drugs is crucial for preventing hearing loss from noise and medications. While promising preclinical and some clinical data exist, further research is urgently needed for FDA-approved inner ear protection.
Area of Science:
- Otolaryngology
- Pharmacology
- Toxicology
Background:
- Noise-induced hearing loss (NIHL) is a significant challenge for military and industrial workers.
- Drug-induced hearing loss is a serious side effect of vital treatments like cisplatin and aminoglycoside antibiotics.
- Current pharmaceutical options for otoprotection (inner ear protection) are lacking.
Purpose of the Study:
- To highlight the urgent need for otoprotective drug agents.
- To review the current state of research in preventing hearing loss.
- To emphasize the necessity for developing pharmaceutical interventions against ototoxicity.
Main Methods:
- Review of preclinical studies on otoprotective agents.
- Analysis of available clinical trial data.
- Identification of research gaps in otoprotection.
Main Results:
- Preclinical research shows promise for several otoprotective strategies.
- Limited clinical trial data supports the potential of some agents.
- No FDA-approved otoprotective drugs are currently available.
Conclusions:
- There is a critical unmet need for FDA-approved otoprotective medications.
- Further research is essential to develop effective drugs for preventing hearing loss.
- Otoprotection strategies require continued investigation for both noise and drug-induced ototoxicity.

01:19Clinical Applications of Epidermal Stem Cells
3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.4K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
697
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.3K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
1.9K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
