Perichondritis has been noted to be the presenting symptom of a number of disease processes marked by immunosuppression, including HIV-associated Non-Hodkin’s Lymphoma, relapsing polychondritis, and—not uncommonly—diabetes ( Caruso 2014 ) ( Levin 1995 [rebelem.com]

In one meta-analysis of 16,184 pediatric patients given systemic ciprofloxacin, the risk of musculoskeletal adverse events attributed to therapy was 1.6%, half of which were arthralgias which resolved upon drug withdrawal ( Adefurin 2011 ). [rebelem.com]

Patients initially experience dull pain, which gradually develops into severe otalgia with a purulent discharge ( Noel 1989 ). Early cases are marked by erythema, swelling, and tenderness of the auricle without notable fluctuance (Chun 2013). [rebelem.com]

[…] even further, providing a good medium for bacteria that could be introduced by the piercing needle or gun.5 Surgery and burns can also cause perichondritis, and there have been rare cases of the infection occurring secondary to furunculosis, chronic ear [jucm.com]

Second intention healing process often causes an ear deformity known as “cauliflower” ear1. The destruction of ear cartilage in cases of unfavorable development, associated with a creased and deforming scar, hampers plastic reconstruction success 5. [bjorl.org]

Traditionally, fluoroquinolones have been avoided in pediatric patients due to fears of arthropathy, however recent literature suggests that risk is abundantly low. [rebelem.com]

Conclusions Our findings suggest that intravenous antibiotic therapy covering S. aureus is sufficient and appropriate empirical treatment in the majority of patients with non-abscess perichondritis. [springermedizin.de]

Also known as: perichondritis infection, Pseudomonas aeruginosa infection. What is perichondritis? The perichondrium is a thin dense layer of tissue that surrounds cartilage and which provides it with nutrients. [nicklauschildrens.org]

The most common microorganism responsible for perichondritis is Pseudomonas Aeruginosa, a gram-negative rod with intrinsic antibiotic resistance mechanisms ( Caruso 2014 ) ( Wu 2011 ). [rebelem.com]

The most commonly found pathogen is Pseudomonas aeruginosa, together with Staphylococcus aureus 6. [bjorl.org]

Abstract Purpose Pseudomonas aeruginosa is commonly found in suppurative perichondritis, but the significant pathogens in non-abscess perichondritis are unclarified. [springermedizin.de]

Antibiotics coverage should be targeted to cover skin flora and Pseudomonas, and if an abscess is present, surgical drainage is also recommended to prevent ear disfigurement. [ncbi.nlm.nih.gov]
