1/6. Late-onset corynebacterium endophthalmitis following laser posterior capsulotomy.Four months following uncomplicated cataract extraction, a patient underwent Nd:YAG laser posterior capsulotomy. Three days later, she presented with pain, hand motions vision, and severe anterior uveitis and vitritis. A coincident retinal detachment led to a delay in diagnosing the etiology of this intraocular inflammation. After recurrent episodes of inflammation that were initially responsive to corticosteroids, the patient underwent a vitrectomy, lens explantation, capsulectomy, and intravitreal antibiotic injections, which resulted in complete resolution of the intraocular inflammation with a best-corrected visual acuity of 20/60. corynebacterium species was ultimately cultured from the capsular tissue. The release of sequestered bacterial organisms must be considered in the differential diagnosis of persistent or unusually intense inflammation following laser posterior capsulotomy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/6. Postoperative corynebacterium macginleyi endophthalmitis.A 72-year-old man with chronic endophthalmitis who received steroid treatment for 3 months came to our center. Sterile endophthalmitis after cataract extraction had been diagnosed. Aqueous samples including smears, classic cultures, and polymerase chain reaction were taken for microbiological study. Amplified dna was sequenced to identify the pathogen. polymerase chain reaction amplification was positive for bacteria. sequence analysis showed corynebacterium macginleyi as the causal agent in 48 hours. The culture and smear stains from the ocular samples were negative. The patient was successfully treated with vancomycin. polymerase chain reaction and subsequent dna-typing were useful in detecting the microorganisms that caused the chronic endophthalmitis.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/6. Endocapsular hypopyon: a clinical sign of localized endophthalmitis.Chronic intraocular infection following cataract extraction and intraocular lens (IOL) implantation has been documented by several authors. We report a case of chronic, bacterial endophthalmitis that clinically correlates with previous pathologic studies in which the focus of infection was sequestered in the capsular sac between the IOL and the posterior lens capsule. Successful management did not require IOL removal.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/6. Coryneform endophthalmitis. Two case reports.Recent clinical studies have emphasized the importance of diphtheroids, previously regarded as nonpathogenic bacteria or contaminants, as causes of ocular disease. We encountered two patients with endophthalmitis following cataract extraction and anterior chamber intraocular lens implantation. Both patients had previously been treated with subconjunctival and/or oral corticosteroids for presumed sterile endophthalmitis. Vitreous cultures in each case yielded pure growth of a diphtheroid that was subsequently identified as coryneform group A-4. The clinical response to standard intraocular therapy with gentamicin and cefazolin was delayed, although both patients eventually had restoration of functional vision. A comparison of the antibiotic minimum inhibitory and minimum bactericidal concentrations of the isolates may help to explain the delayed response to therapy seen in these two patients.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/6. Fatal acute bacterial myocarditis after dentoalveolar abscess.A 19 year old woman presented with chest pain after a dental extraction for a dentoalveolar abscess. Electrocardiographic and serum isoenzyme changes were consistent with acute anterior myocardial infarction. At autopsy bacteria were demonstrated, within the myocardium in the absence of a myocardial abscess or endocarditis. This case illustrates the occurrence of isolated acute bacterial myocarditis after a dental extraction.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
6/6. corynebacterium minutissimum endophthalmitis: management with antibiotic irrigation of the capsular bag.Chronic endophthalmitis, due to corynebacterium minutissimum, developed in a patient following uncomplicated extracapsular cataract extraction and posterior chamber intraocular lens (PC-IOL) implantation. In this case, which to our knowledge is the first reported case of corynebacterium minutissimum endophthalmitis, chronic inflammation persisted for 8 months with fluctuations in the inflammation. The specimens from the capsular bag yielded positive culture, but the vitreous culture was negative. The case was successfully treated by a capsular bag irrigation with vancomycin.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
