INTRODUCTION: Although the majority of those exposed to liquid laundry detergent capsules remain asymptomatic or suffer only minor clinical features after exposure, a small proportion develop central nervous system depression, stridor, pulmonary aspiration and/or airway burns following ingestion or conjunctivitis and corneal ulceration following eye exposure. As a consequence, the International Association for Soaps, Detergents and Maintenance Products (AISE) established a Product Stewardship Programme in Europe, requiring that safety measures be implemented to reduce the visibility of, and restrict access to, these detergent capsules by small children...

Pseudomonas aeruginosa (PA)-induced keratitis is a rapidly progressive ocular infectious disease that often leads to inflammatory epithelial edema, stromal infiltration, tissue destruction, corneal ulceration, and vision loss. In this study, we investigate the role of tripartite motif 8 (TRIM8) in regulating the inflammatory process of PA-induced keratitis. The expression of TRIM8 was increased in mouse corneas and in vitro-cultured macrophages after PA infection. Knockdown of the expression of TRIM8 significantly inhibited the activation of NF-κB signaling and decreased the production of pro-inflammatory cytokines both in vivo and in vitro after infected with PA...

The diagnosis of keratitis is based on visual exam, tissue cytology, and standard microbial culturing to determine the type of the infectious pathogen. To prescribe appropriate therapy, it is important to distinguish between bacterial, fungal, and viral keratitis, as the treatments are quite different. Diagnosis of the causative organism has a substantial prognostic importance. Further, timely knowledge of the nature of the pathogen is also critical to adapt therapy in patients unresponsive to empiric treatment options, which occurs in 10% of all cases...

Reactive arthritis is occasionally associated with conjunctivitis and uveitis, but rarely keratitis. The authors describe a patient with paracentral anterior stromal keratitis with overlying epithelial erosion and multiple satellite subepithelial infiltrates. The initial appearance and the severe pain were suggestive of an infectious process. Recovery was rapid following introduction of topical steroid, with features suggesting an immune process in the recovery phase. The authors suggest that a history of arthritis and/or recent enteritis should be sought in the work-up of an atypical keratitis with or without epithelial defect...

OBJECTIVE: Corneal ulcers are commonly encountered in pinnipeds. Prolonged oral antibiotics and topical ophthalmic solutions may not be practical to administer, and novel treatment techniques are desired. Thermodynamic gels are a potential solution because they hold antimicrobials at the site of injection, slowly releasing drug. This study investigated the clinical efficacy of antibiotic-impregnated poloxamer gel in management of corneal ulceration. ANIMAL STUDIED: Twenty-six California sea lions undergoing rehabilitation at The Marine Mammal Center...

Since the severe corneal ulceration of mouse cornea is known to occur with inflammation. As one of imperative matrix metalloproteinase, the potential roles of matrix metalloproteins 9 (MMP9) in corneal ulceration and keratitis are still unveiled caused by fungal invasion. In this study, Candida albicans (CA) inoculated wild-type KM mice cornea was used as a model pathogen in corneal inflammation.  CA invasion significantly stimulated the expression of collagen IV and MMP9 detected by RT-PCR, Real-time PCR and Immunofluorescent staining in mouse cornea as soon as 6 hours post infection, and relatively decreased at 1 day post infection...
