Historical perspective on the use of otic antimicrobial agents

Surgical Outcomes of Type 1 Tympanoplasty in Chronic Otitis Media in Paediatric Patients: A Prospective Study

Objectives: To observe the surgical outcome of type 1 tympanoplasty in paediatric patients in the form of graft uptake and audiological improvement. Materials and methods: A prospective study was done in which 40 paediatric patients in age group 6-16 years, diagnosed of chronic otitis media, were taken up for tympanoplasty under general anaesthesia. Patients were followed in post operative period at 4, 6 and 12 weeks for assessment of graft status and audiological evaluation. Results: In this study, we found surgical success rate in the form of graft uptake in 80% of the cases and audiological improvement in 75% of the cases. Conclusion: Tympanoplasty is safe and effective in children with adequate graft uptake and audiological outcome.

Triangulation of pharmacoepidemiology and laboratory science to tackle otic quinolone safety

Background

The scientific method requires studies with high internal and external validity. Though both are necessary, they do not go hand‐in‐hand: The more controlled a study is to enhance internal validity, the less applicable to real‐world clinical care, and vice versa. In the many instances where evidence from clinical trials is not available, scientific inference must rely on more extreme approaches on this spectrum, such as mechanistic (limited generalizability/strong bias control) and real‐world evidence (RWE) studies (higher generalizability/lesser bias control).

Objectives

Illustrate how triangulating mechanistic and RWE studies can enhance scientific inference by delivering the supporting evidence for both.

Methods

We describe our research on an unexpected and highly unlikely drug safety issue: the risk of tympanic membrane (TM) perforations resulting from otic quinolone therapy. Tightly controlled laboratory studies using cell culture and rodent models were complemented with pharmacoepidemiological studies of real‐world data to translate mechanistic findings and corroborate RWE.

Results

We present a cascade of mechanistic and RWE studies investigating fibroblast cytotoxicity, delayed healing of perforated TMs, and spontaneous TM perforations after otic quinolone exposure, all suggesting local tissue toxicity.

Conclusion

Triangulation of mechanistic and RWE studies allowed incremental progress toward robust evidence on otic quinolone toxicity.

Earache

Earache, a common emergency department presentation, may be caused by a variety of conditions, some distant from the ear. This article discusses the diagnosis and treatment of acute otitis media, otitis media with effusion, otitis externa, otitis media with ruptured tympanic membrane or tympanostomy tubes, malignant otitis externa, mastoiditis and petrositis, traumatic ruptured tympanic membrane, cerumen impactions, and foreign bodies in the ears.

Ciprofloxacin 0.3%/dexamethasone 0.1% sterile otic suspension for the topical treatment of ear infections: a review of the literature

The objective of this article is to review the literature related to ciprofloxacin 0.3% and dexamethasone 0.1% sterile otic suspension. A systematic literature search utilizing Medline was conducted to identify peer-reviewed articles related to safety and efficacy. A total of 47 publications were identified and reviewed herein. The literature supports the use of antibiotic/antiiflammatory combination ear drops in the treatment of both acute otitis externa and acute otitis media in pediatric patients with tympanostomy tubes. Ciprofloxacin/dexamethasone has been demonstrated as safe and effective with regard to clinical cures and microbiological eradication of pathogens in either disease with low treatment failure rates. Additionally, the literature also provides clear evidence for the contribution of dexamethasone when added to ciprofloxacin for the topical treatment of ear infections.

Chronic suppurative otitis media: a review

OBJECTIVES

Chronic suppurative otitis media (CSOM) remains one of the most common childhood chronic infectious diseases worldwide. Although microbial, immunological, and genetically determined factors, as well as Eustachian tube characteristics, are supposed to be involved in the pathogenesis of CSOM, many aspects of the pathogenesis of CSOM still need to be clarified. Optimal treatment strategy has not been established yet. The objective of this review is to present and evaluate the current state of knowledge of CSOM.

DESIGN

Systematic narrative review.

METHODS

A PubMed search (1966-January 2005) was performed for studies on epidemiology, pathogenesis, clinical management, and complications of CSOM. All included articles were categorized according to level of evidence.

RESULTS

Five hundred and fifty papers were identified, of which 79 were found to be relevant for this review. The definition of CSOM was found to vary. CSOM is a multifactorial disease. Regarding management of CSOM, there is no consensus as to what the optimal management strategy should entail. No convincing evidence is available for most medical and surgical therapies. Topical quinolones have proven effective, but need further monitoring regarding adverse effects.

CONCLUSIONS AND RECOMMENDATIONS

Important goals in research of CSOM should be achieving consensus about the definition of CSOM and gaining more in-depth knowledge of the pathogenesis of CSOM, especially the role of innate and adaptive immunity. There is also a need for further well-designed studies on the effectiveness of various management strategies for CSOM.

Management of the draining ear in children

There are a variety of causes of otorrhea in children. The most important factor in reaching the proper diagnosis and providing relief of the problem is aural toilet. Once adequate debridement has been performed, the diagnosis is usually clearer, and treatment with ototopicals is significantly more effective. Most cases of otorrhea are due to infection or granulation tissue and can be managed initially with appropriately selected ototopical medication, thereby avoiding the risks and side effects of systemic therapy and the need for referral to a specialist. However, otorrhea in children that is refractory to medical therapy may be due to retained tympanostomy tubes or insidious pathology such as cholesteatoma or malignancy. In such cases, prompt referral to the otolaryngologist can facilitate accurate diagnosis and successful management.
