Insights

Topical ciprofloxacin effectively treated ear infections in children with persistent otorrhea. This study found the antibiotic safe and effective, with no systemic absorption or adverse effects observed in pediatric patients.

Area of Science:

  • Pediatric Otolaryngology
  • Infectious Diseases
  • Pharmacokinetics

Background:

  • Otorrhea is a common complication following tympanostomy tube placement in children.
  • Persistent otorrhea can lead to treatment challenges and potential hearing impairment.
  • Pseudomonas aeruginosa is a frequent causative agent in pediatric otorrhea.

Purpose of the Study:

  • To assess the efficacy of topical ciprofloxacin in treating pediatric otorrhea.
  • To evaluate the systemic absorption of ototopically administered ciprofloxacin.
  • To determine the safety profile of topical ciprofloxacin in children.

Main Methods:

  • A nonrandomized, open-label pilot trial was conducted in a pediatric otolaryngology clinic.
  • Patients aged 3-8 years with persistent otorrhea and Pseudomonas aeruginosa infection received topical ciprofloxacin for 14 days.
  • Pharmacokinetic analysis was performed to measure systemic absorption, alongside audiometry and clinical evaluations for efficacy and safety.

Main Results:

  • Topical ciprofloxacin demonstrated high efficacy, with 10 of 11 infected ears showing improvement or cure by day 7, and complete cure by days 14 and 44.
  • No systemic absorption of ciprofloxacin was detected in any of the pediatric participants.
  • No adverse effects were reported, and bone conduction audiometry results normalized in all children by day 14.

Conclusions:

  • Topical ciprofloxacin is a safe and effective treatment for pediatric otorrhea unresponsive to other therapies.
  • The drug exhibits minimal to no systemic absorption when administered topically in children.
  • This treatment offers a promising alternative for managing challenging cases of otorrhea in pediatric patients.

Angle Closure Glaucoma: Treatment01:28

Angle 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...

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
Microbiome of the Eye01:22

Microbiome 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...
