1/194. exophiala (Wangiella) dermatitidis keratitis after keratoplasty.We report the first French case of an intraocular infection due to exophiala (Wangiella) dermatitidis. Two months after a second corneal transplant for congenital hereditary endothelial dystrophy, the patient presented with ocular pain and corneal infiltrates leading to the graft rejection. Diagnosis was established by positive direct examination and cultures of the same fungus from corneal buttons, iris biopsies and ablated sutures.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/194. rhodotorula sp. infection in corneal interface following lamellar keratoplasty--a case report.PURPOSE: To report an unusual organism causing infection following lamellar keratoplasty. METHOD: Case report. RESULT: Both gram stain smear and culture from the interlamellar bed revealed rhodotorula sp., a red yeast as a causative agent. CONCLUSION: rhodotorula sp. can cause corneal lamellar graft infection.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
3/194. aspergillus mycetoma in a secondary hydroxyapatite orbital implant: a case report and literature review.OBJECTIVE: The authors describe the first case report of a fungal abscess within a hydroxyapatite orbital implant in a patient who had undergone straightforward secondary hydroxyapatite implant surgery. DESIGN: Case report and literature review. INTERVENTION: Four months postoperatively after pegging and 17 months after original implant placement, chronic discharge and socket irritation became evident. Recurrent pyogenic granulomas were a problem, but no obvious area of dehiscence was present over the implant. The peg and sleeve were removed 31 months after pegging (44 months after original placement of the implant). The pain and discharge did not resolve, and the entire hydroxyapatite orbital implant was removed 45 months after sleeve placement and 58 months after initial implant placement. The pain and discharge settled rapidly. MAIN OUTCOME MEASURES: Cultures and histopathology. RESULTS: Results of bacterial cultures were negative. Results of histopathologic examination of the implant disclosed intertrabecular spaces with multiple clusters of organisms consistent with aspergillus. CONCLUSIONS: Persistent orbital discomfort, discharge, and pyogenic granulomas after hydroxyapatite implantation should cause concern regarding potential implant infection. The authors have now shown that this implant infection could be bacterial or fungal in nature. This is essentially a new form of orbital aspergillus, that of a chronic infection limited to a hydroxyapatite implant.- - - - - - - - - - ranking = 3keywords = infection (Clic here for more details about this article) |
4/194. chrysosporium parvum keratomycosis.PURPOSE: To report a case of corneal infection with chrysosporium parvum, a filamentous fungus usually associated with pulmonary infections. methods: A 43-year-old Saudi man had a corneal stromal infiltrate and perforation of his left eye. He was treated with a therapeutic penetrating keratoplasty and topical and systemic antifungal therapy. Corneal scrapings, microbiologic evaluation, and histopathologic examination of the surgical specimen were performed to establish the diagnosis. After the development of recurrent stromal keratitis at the graft-host junction, similar diagnostic and therapeutic maneuvers were performed. RESULTS: Corneal scrapings and histopathologic examination were positive for numerous septate hyphae with endospores, consistent with a diagnosis of filamentous keratomycosis. Microbiologic isolation confirmed the diagnosis of chrysosporium parvum. Similar diagnostic maneuvers for recurrent keratitis produced identical results. CONCLUSION: To our knowledge, this is the first case of chrysosporium parvum keratomycosis.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
5/194. Mycotic keratitis due to Curvularia senegalensis and in vitro antifungal susceptibilities of Curvularia spp.A case of mycotic keratitis due to Curvularia senegalensis is reported. This case represents the third known reported infection caused by this rare species. Fungal hyphae were detected in corneal scrapings, and repeated cultures were positive for this fungi. The patient was presumed cured after a corneal transplant and treatment with itraconazole, but the infection recurred and the patient is waiting for a keratoplasty. The in vitro antifungal susceptibilities of the case strain and another 24 strains belonging to seven species of Curvularia were tested for six antifungal agents. With the exception of flucytosine, and occasionally fluconazole, the other drugs assayed (amphotericin b, miconazole, itraconazole, and ketoconazole) were highly effective in vitro.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
6/194. Treatment of acanthamoeba keratitis combined with fungal infection with polyhexamethylene biguanide.From July 1996 to March 1997, three cases of acanthamoeba keratitis combined with fungal infection were diagnosed and treated at our ophthalmic department. Specimens from all of these cases were obtained by corneal scraping, keratectomy and anterior chamber paracentesis. The diagnosis was confirmed by either the results of smear test or pathology reports. All of these patients received aggressive treatment with polyhexamethylene biguanide (PHMB) 0.02%, fluconazole, and anegyn eye drops. After the infection had been controlled without extension, therapeutic penetrating keratoplasty was performed on all of these patients despite the existence of infiltration beyond the edge of the graft. Postoperatively, eye drops were tapered gradually, and treatment was continued for 1 to 2 months. All three cases achieved good results and there was no recurrence of infection. Two cases had visual acuity of 20/100 and 20/20, while the other one perceived hand movement only due to later graft rejection. These cases suggest that early diagnosis and immediate use of PHMB and anti-fungal agents are effective in the treatment of acanthamoeba keratitis combined with fungal infection.- - - - - - - - - - ranking = 8keywords = infection (Clic here for more details about this article) |
7/194. Phototherapeutic keratectomy of a corneal scar due to presumed infection after photorefractive keratectomy.This case involves a 25-year-old patient who suffered from corneal ulceration several days after photorefractive keratectomy (PRK). A central scar developed, resulting in discomfort and reduction in visual acuity. Four months later, the scar was treated by phototherapeutic keratectomy (PTK) (25 microns depth, 5 mm ablation zone). Some scar tissue was left, but it cleared slowly and steadily over the next few years. The induced hyperopia decreased from 5.00 to 1.37 diopters spherical equivalent within 28 months postoperatively. Best corrected visual acuity increased from 20/60 preoperatively to 20/20 at 28 months postoperatively. Surgeons can encourage patients with postinfectious scars after PRK to try at least 1 PTK treatment.- - - - - - - - - - ranking = 4keywords = infection (Clic here for more details about this article) |
8/194. survival after rhino-orbital-cerebral mucormycosis in an immunocompetent patient.OBJECTIVE: Rhino-orbital-cerebral mucormycosis is usually associated with a poor prognosis and is almost exclusively seen in immunocompromised patients. We report the third documented case of rhino-orbital-cerebral mucormycosis caused by Apophysomyces elegans (a new genus of the family Mucoraceae first isolated in 1979) in an immunocompetent individual. Orbital exenteration and radical debridement of involved adjacent structures combined with intravenous liposomal amphotericin resulted in patient survival. DESIGN: Interventional case report. METHOD: A 59-year-old immunocompetent white man sustained a high-pressure water jet injury to the right inner canthus while cleaning an air conditioner filter. He later had "orbital cellulitis" develop that did not respond to antibiotics and progressed to orbital infarction. Imaging studies and biopsy results led to a diagnosis of mucormycosis. Tissue culture grew Apophysomyces elegans, a new genus of the family Mucoraceae first isolated in 1979. Orbital exenteration and radical debridement of involved adjacent structures, combined with intravenous liposomal amphotericin, resulted in patient survival. RESULTS: After orbital exenteration and debridement of involved adjacent structures along with intravenous liposomal amphotericin, our patient has remained free from relapse with long-term follow-up. CONCLUSIONS: The agent causing this case of rhino-orbital-cerebral mucormycosis (Apophysomyces elegans) contrasts with the three genera most commonly responsible for mucormycosis (rhizopus, Mucor, and absidia) in that infections with this agent tend to occur in warm climates, by means of traumatic inoculation, and in immunocompetent patients. Rhino-orbital-cerebral mucormycosis should be considered in all patients with orbital inflammation associated with multiple cranial nerve palsies and retinal or orbital infarction, regardless of their immunologic status. A team approach to management is recommended for early, appropriate surgery and systemic antifungal agents.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
9/194. acremonium keratitis in a patient with herpetic neurotrophic corneal disease.fungi belonging to the genus acremonium Link ex Fries 1821 are ubiquitous environmental contaminants and soil saprophytes, but are infrequent pathogens in humans. These filamentous fungi (previously known as Cephalosporium) are an uncommon cause of mycotic keratitis. As in the case of other filamentous fungi, corneal trauma with contaminated matter is the most frequent risk factor for the infection. We report in this paper a case of keratomycosis caused by Acremoniumpotronii, in a patient with a history of herpetic keratitis. Medical treatment with amphotericin b was unsuccessful and the infection eventually resolved with penetrating keratoplasty.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
10/194. Fungal keratitis after laser in situ keratomileusis: a case report.PURPOSE: To report a case of fungal keratitis resulting after laser in situ keratomileusis (LASIK). methods: A 38-year-old white man in good health developed a corneal infiltrate with laboratory confirmation of fungal keratitis after LASIK. Corneal scrapings were taken. silver stain was positive for hyphae. culture was positive for Curvularia sp. The patient was started on intensive natamycin 5% and amphotericin 0.15% topical therapy. RESULTS: The patient's keratitis was successfully treated with intensive antifungal therapy. CONCLUSIONS: Infectious keratitis is a rare but a serious potential complication after LASIK. To our knowledge, no previous case of fungal keratitis after LASIK has been reported. This case emphasizes the importance of surveillance for infection after LASIK.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
