Metastatic meningococcal endophthalmitis, although rare, is a rapidly progressive and sight-threatening infection. We present a 10-month-old infant with meningococcal meningitis who developed unilateral metastatic endophthalmitis. If patients develop a sepsis-like picture with cloudy cornea and purulent conjunctivitis, we have to consider the possibility of endophthalmitis and full ophthalmological evaluations are indicated. Treatment should be started as early as possible. The outcome of endophthalmitis is frequently permanent visual impairment. Endophthalmitis is a true medical emergency requiring early antibiotic therapy with full dose of antimicrobials to avoid morbidity and blindness.

Cytotoxic effects of denture base materials on a permanent human oral epithelial cell line and on primary human oral fibroblasts in vitro.

PURPOSE: The objective of this study was to determine the cytocompatibility of three different extracts of denture base resins and to compare the cytotoxic effect of these materials on a human oral epithelial KB cell line and primary human oral fibroblasts derived from buccal mucosa. MATERIALS AND METHODS: Set specimens from a heat-cured resin, a self-cured resin, and a light-cured resin were eluted with culture medium for 1, 3, and 5 days. Cytotoxicity was judged using tetrazolium bromide reduction assay. RESULTS: The eluates from self-cured, heat-cured, and light-cured denture base resins were cytotoxic to primary human buccal fibroblast cultures and KB cells. Self-cured resin was the most toxic denture base material among the chemicals tested in all cultures. The cytotoxicity decreased in the order of self-cured resin > heat-cured resin > light-cured resin for KB cells. The rank for buccal fibroblast cells was self-cured resin > heat-cured resin > light-cured resin. CONCLUSION: The influence of the cytotoxicity depended on the materials tested and the cell culture system used. The use of both permanent and primary cells is recommended for a better screening of the cytotoxic effects of denture base resins.

Pseudomonas aeruginosa endophthalmitis in prematurity: report of two cases.

Invasive bacterial eye infections in the neonate range from perforating keratitis to endophthalmitis. Endophthalmitis secondary to Pseudomonas aeruginosa has gained clinical and therapeutic importance since mortality rates are high and prognosis concerning preservation of vision is poor, especially in premature infants. We presented two cases with meningitis, septicemia and P. aeruginosa endophthalmitis. If premature infants develop a sepsis-like picture with cloudy cornea and purulent conjunctivitis, we have to consider the possibility of endophthalmitis and do a full ophthalmologic evaluation. Treatment should be started early and consists of systemic antibiotic therapy, as in septicemia. As P. aeruginosa spreads easily, prompt isolation and strict handwashing are indicated.
