Purpose:
To describe a case of chronic exogenous Exophiala dermatitidis endophthalmitis.
Methods:
Retrospective chart review and case report.
Results:
A 60-year-old man with history of chronic herpes zoster keratitis complicated by secondary fungal keratitis treated with penetrating keratoplasty presented with a white cataract, chronic anterior uveitis, and counting fingers vision in the left eye. Combined cataract extraction and diagnostic vitrectomy revealed positive cultures and polymerase chain reaction-based testing for E. dermatitidis-the same organism responsible for the keratitis. The patient was treated with multiple oral, intravenous, and intravitreal antifungal agents. Ultimately, the corneal infection recurred and the patient elected to undergo enucleation. Filamentous fungi consistent with E. dermatitidis infection were identified in the cornea of the enucleation specimen.
Conclusion:
Although rare, Exophiala species can cause exogenous endophthalmitis. Chronic endophthalmitis should be suspected in patients who develop persistent intraocular inflammation after infectious keratitis.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
