Summary
Topical fluoroquinolones offer effective and safe treatment for various eye and ear infections, including bacterial keratitis and otitis media. These broad-spectrum antibiotics are well-tolerated, convenient, and show limited bacterial resistance, making them valuable therapeutic options.
Area of Science:
- Ophthalmology and Otolaryngology
- Infectious Diseases
- Pharmacology
Background:
- Topical fluoroquinolones are increasingly utilized for ocular and otic infections.
- They exhibit broad-spectrum activity against common pathogens like Staphylococcus aureus and Pseudomonas aeruginosa.
Purpose of the Study:
- To evaluate the efficacy and safety of topical fluoroquinolones in treating eye and ear infections.
- To assess their suitability for different conditions, including acute otitis externa, otitis media with tympanic membrane perforation, and bacterial keratitis.
Main Methods:
- Clinical efficacy and safety data from studies on topical fluoroquinolone use in ophthalmology and otology were reviewed.
- Comparative analyses with existing treatments were considered.
Main Results:
- Topical fluoroquinolones are as effective as traditional otic preparations for acute otitis externa.
- They are effective and safe for otitis media with tympanic membrane perforation, approved for children, and suitable for prolonged use due to lack of ototoxicity.
- While not ideal for uncomplicated conjunctivitis, they simplify treatment for bacterial keratitis.
Conclusions:
- Topical fluoroquinolones provide a well-tolerated, convenient, and effective treatment option for specific bacterial eye and ear infections.
- Current bacterial resistance to these agents appears limited, supporting their continued clinical utility.

01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:16Drugs Used in Upper Respiratory Disorders: Overview
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
