[PMID: 37989464 DOI: 10.1016/j.oret.2023.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 11/06/2023] [Accepted: 11/14/2023] [Indexed: 11/23/2023]
Abstract
PURPOSE To investigate the factors associated with treatment outcomes of postcataract surgery fungal endophthalmitis outbreaks related to contaminated viscoelastics. DESIGN Retrospective analysis of clinical data from multiple institutions. SUBJECTS This study included 228 eyes of 210 patients who were diagnosed with postcataract surgery fungal endophthalmitis related to the use of viscoelastic material (Unial, Unimed Pharmaceutical Inc); they were followed up for 6 months after the diagnosis. METHODS Clinical features and causative species were identified and treatment outcomes were analyzed in patients who underwent 6 months of follow-up. Propensity score matching was conducted to elucidate the impact of vitrectomy timing and intraocular lens (IOL) removal on treatment outcomes. MAIN OUTCOME MEASURES Clinical factors and selection of treatment modalities associated with treatment outcomes at 6 months. RESULTS Baseline visual acuity (P < 0.01), age (P = 0.05), and the presence of corneal edema (P < 0.01) were closely associated with poor best-corrected visual acuity (BCVA) at 6 months. Patients who underwent immediate vitrectomy after diagnosis showed significantly better BCVA at 6 months (mean logarithm of minimum angle of resolution 0.26 ± 0.43 vs. 0.52 ± 0.52, P = 0.03) and greater degree of visual improvement (mean -0.17 ± 0.37 improvement vs. 0.10 ± 0.57 deterioration, P = 0.03) than those who underwent deferred vitrectomy. Patients who underwent IOL removal during vitrectomy required a lower number of intravitreal antifungal agent injections (mean 8.9 ± 9.1 vs. 16.7 ± 12.2, P < 0.01) and showed a lower incidence of repeated vitrectomy (20% vs. 82%, P < 0.01) than in those without IOL removal. CONCLUSIONS In postcataract fungal endophthalmitis, prompt vitrectomy at the time of diagnosis resulted in better treatment outcomes, and IOL removal reduced the treatment burden. Prompt and aggressive surgical intervention should be considered for postcataract fungal endophthalmitis.

Abstract
Background: Fungus endophthalmitis is a rare and serious infection that is treated with systemic and topical antifungal drugs. There is no clear consensus on the treatment of fungal endophthalmitis with intravitreal injections (IVIs) of voriconazole. This systematic review aims to summarize the literature on IVIs of voriconazole for fungal endophthalmitis. Methods: We conducted a systematic review of the literature to determine the effectiveness and safety of IVIs of voriconazole in the treatment of fungal endophthalmitis. We searched databases such as PubMed and Embase using the following search terms "Endophthalmitis" AND "Intravitreal Injections" AND "Voriconazole" with date limits of January 1, 1900, to December 31, 2022. We included all reports on humans, which described clinical outcomes of IVIs of voriconazole in the treatment of fungal endophthalmitis, including randomized controlled trials (RCTs) and case series. A descriptive synthesis of the data was conducted with a pooling of data for interventions. Results: One RCT and 21 retrospective studies were analyzed in this review. In these reports, a wide range of heterogeneous treatment regimens was used, including IVI in combination with other drugs, systemic therapy in combination with other agents, and surgery. Combined with other treatments, intravitreal voriconazole results in a favorable anatomical and clinical cure that was well tolerated. Conclusions: Reports on IVIs of voriconazole for fungal endophthalmitis demonstrate a heterogeneous approach to treatment. Of these, IVIs of voriconazole in anatomical and clinical outcomes appeared to be highly effective, although more data on its safety are needed.

Abstract
Nosocomial clusters of fungal infections, whilst uncommon, cannot be predicted and are associated with significant morbidity and mortality. Here, we review reports of nosocomial outbreaks of invasive fungal disease to glean insight into their epidemiology, risks for infection, methods employed in outbreak detection including genomic testing to confirm the outbreak, and approaches to clinical and infection control management. Both yeasts and filamentous fungi cause outbreaks, with each having general and specific risks. The early detection and confirmation of the outbreak are essential for diagnosis, treatment of affected patients, and termination of the outbreak. Environmental sampling, including the air in mould outbreaks, for the pathogen may be indicated. The genetic analysis of epidemiologically linked isolates is strongly recommended through a sufficiently discriminatory approach such as whole genome sequencing or a method that is acceptably discriminatory for that pathogen. An analysis of both linked isolates and epidemiologically unrelated strains is required to enable genetic similarity comparisons. The management of the outbreak encompasses input from a multi-disciplinary team with epidemiological investigation and infection control measures, including screening for additional cases, patient cohorting, and strict hygiene and cleaning procedures. Automated methods for fungal infection surveillance would greatly aid earlier outbreak detection and should be a focus of research.

Abstract
Incidences of post pars plana vitrectomy (PPV) endophthalmitis vary between 0.02% and 0.13%, and infectious endophthalmitis in silicone oil-filled eyes is even rarer. We performed a literature review to describe the incidence, protective and predisposing factors, causative pathogens, management options, and prognosis of infectious endophthalmitis in silicone oil-filled eyes. Various studies have elucidated different aspects of this condition. Causative pathogens commonly include commensals. Traditional management involves the removal of silicone oil (SO), intravitreal antibiotics and then SO re-injection. Alternatively, injecting intravitreal antibiotics into silicone oil-filled eyes has also been reported. Visual prognoses are uniformly guarded. Due to the uncommon nature of this condition, studies are limited either by their retrospective design or by small sample sizes. However, observational studies, case series, and case reports can play an important role in rare conditions until larger studies are conducted. This comprehensive review aims to summarise the information available in the literature, to act as a good source for ophthalmologists looking for answers on this topic, and to suggest areas for future development.

Abstract
Importance Fungal endophthalmitis caused by contaminated medical products is extremely rare; it follows an intractable clinical course with a poor visual prognosis. Objective To report the epidemiologic and clinical features and treatment outcomes of a nationwide fungal endophthalmitis outbreak after cataract surgery as a result of contaminated viscoelastic agents in South Korea. Design, Setting, and Participants This was a retrospective case series analysis of clinical data from multiple institutions in South Korea conducted from September 1, 2020, to October 31, 2021. Data were collected through nationwide surveys in May and October 2021 from the 100 members of the Korean Retinal Society. Patients were diagnosed with fungal endophthalmitis resulting from the use of the viscoelastic material sodium hyaluronate (Unial [Unimed Pharmaceutical Inc]). Data were analyzed from November 1, 2021, to May 30, 2022. Main Outcomes and Measures The clinical features and causative species were identified, and treatment outcomes were analyzed for patients who underwent 6 months of follow-up. Results The fungal endophthalmitis outbreak developed between September 1, 2020, and June 30, 2021, and peaked in November 2020. An official investigation by the Korea Disease Control and Prevention Agency confirmed contamination of viscoelastic material. All 281 eyes of 265 patients (mean [SD] age, 65.4 [10.8] years; 153 female individuals [57.7%]) were diagnosed with fungal endophthalmitis, based on clinical examinations and supportive culture results. The mean (SD) time period between cataract surgery and diagnosis was 24.7 (17.3) days. Patients exhibited characteristic clinical features of fungal endophthalmitis, including vitreous opacity (212 of 281 [75.4%]), infiltration into the intraocular lens (143 of 281 [50.9%]), and ciliary infiltration (55 of 281 [19.6%]). Cultures were performed in 260 eyes, and fungal presence was confirmed in 103 eyes (39.6%). Among them, Fusarium species were identified in 89 eyes (86.4%). Among the 228 eyes included in the treatment outcome analysis, the mean (SD) best-corrected visual acuity improved from 0.78 (0.74) logMAR (Snellen equivalent, 20/120 [7.3 lines]) to 0.36 (0.49) logMAR (Snellen equivalent, 20/45 [4.9 lines]) at 6 months. Furthermore, disease remission with no signs of fungal endophthalmitis (or cells in the anterior chamber milder than grade 1) was noted in 214 eyes (93.9%). Conclusions and Relevance This was a retrospectively reviewed case series of a fungal endophthalmitis outbreak resulting from contaminated viscoelastic material. Findings of this case series study support the potential benefit of prompt, aggressive surgical intervention that may reduce treatment burden and improve prognosis of fungal endophthalmitis caused by contaminated medical products.

Abstract
(1) Background: We aimed to systematically review the current literature to evaluate if in patients with postoperative endophthalmitis treated with pars plana vitrectomy, silicone oil tamponade could provide a useful contribution to the control and eradication of infection and if it could influence anatomical recovery and functional outcome. (2) Randomized controlled trials, cross-sectional studies, case series, and case reports published in the English language in peer-reviewed journals were included. No restriction was placed based on the study location. We used medical subject headings (MeSH) and text words. We searched MEDLINE (OVID and PubMed), Google Scholar, ISI Web of Science (Thom-on-Reuters), and the Cochrane Library (Wiley) from January 1995 to the present. To ensure literature saturation, we scanned the reference lists of included studies or relevant reviews identified through the search. Risk of Bias was assessed using the Newcastle-Ottawa scale for longitudinal studies and Cochrane risk-of-bias tool for randomized trials. (3) Results: abstracts of 75 articles were selected for full-text reading; after full-text reading, 44 articles were taken into consideration in the systematic review. 5 out of 7 in vitro experimental studies demonstrated antimicrobial activity against different species of bacteria and fungi. The use of SO as endotamponade associated with PPV led to better visual acuity and a lower rate of retinal detachment and the need for additional surgery. (4) Conclusions: Silicone oil reduces the risk of postoperative retinal detachment, especially in case of undetected retinal breaks, produces compartmentalization of the eye, may lead to early visual recovery, allows laser photocoagulation, prevents severe postoperative hypotony and has antimicrobic activity due to an inhibitory effect for several species of pathogens. Concerns regarding possible toxic effects on the retina and optic disc, compartmentalization and impaired washout of pathogen toxins have been reported. It may also influence intravitreal antibiotic distribution and clearance.

Abstract
Intraocular transmission of exogenous pathogens in cataract surgery can lead to endophthalmitis. This review evaluates the features of endophthalmitis clusters secondary to pathogen transmission in cataract surgery. Articles reporting on pathogen transmission in cataract surgery were identified via searches of Ovid MEDLINE, EMBASE, and Cochrane CENTRAL, and a total of 268 eyes from 24 studies were included. The most common source of infectious transmission was attributed to a contaminated intraocular solution (ie, irrigation solution, viscoelastic, or diluted antibiotic; n = 10). Visual acuity at presentation with infectious features was 1.89 logMAR (range: 1.35 to 2.58; ∼counting fingers) and 1.33 logMAR (range: 0.04 to 3.00; Snellen: ∼20/430) at last follow-up. Patients with diabetes had worse outcomes compared with patients without diabetes. The most frequently isolated pathogen from the infectious sources was Pseudomonas sp. (50.0%). This review highlights the various routes of pathogen transmission during cataract surgery and summarizes recommendations for the detection, prevention, and management of endophthalmitis clusters.

Abstract
PURPOSE To study the clinical profile and management of a case of fungal postoperative endophthalmitis caused by fusarium solani. CASE REPORT A 40-year-old male underwent an uneventful cataract surgery developed postoperative endophthalmitis. The infection was fulminant and was treated aggressively with pars plana vitrectomy with intravitreal and oral antifungals. The microbiology culture of vitreous sample showed fusarium solani. There was a late recurrence in the form of a fungal ball behind the iris after 6 months of the initial episode. This fungal ball was then managed by transscleral cryotherapy. The eye became hypotonus due to chronic inflammation and silicone oil was instilled to salvage the eye. CONCLUSION Fusarium endophthalmitis needs an aggressive management. Due to late recurrence regular follow-up is mandatory. Early vitrectomy with oral and intravitreal voriconazole is the treatment of choice. Transscleral cryotherapy is a useful option to treat fungal balls behind the iris tissue.

Abstract
PURPOSE To report toxic posterior segment syndrome after dropless cataract surgery using locally compounded triamcinolone-moxifloxacin. METHODS A retrospective case review of 7 patients presenting with a decrease in visual acuity after dropless cataract surgery. RESULTS All patients experienced significant reductions in best-corrected visual acuity of the postoperative eye ranging from 20/40 to count finger at 4 feet (average best-corrected visual acuity 20/220) immediately after surgery. The presenting symptoms included flashes, floaters, photophobia, glare, halos, visual distortions, and problems assessing colors. In three cases, foveal retinal pigment epithelium changes were noted on dilated fundus exam (DFE). Ellipsoid zone loss was noted on ocular coherence tomography in five of the seven affected eyes. Electrophysiology testing in five of the seven affected eyes demonstrated large decreases in full-field electroretinogram amplitude, oscillatory potentials, multifocal electroretinogram, and visual evoked potential, along with a negative electroretinogram. One patient was treated with a dexamethasone implant, but no improvement in visual acuity was noted. CONCLUSION This is the first case series of toxic posterior segment syndrome occurring secondary to intracameral compounded triamcinolone-moxifloxacin in dropless cataract surgery. The FDA has attributed the toxicity to abnormally high levels of the binding agent poloxamer 407 in the compounded medication. Clinicians should be aware of this phenomenon and exhibit caution when using compounded medications.

Abstract
Purpose To compare short-term non-infectious clinical outcomes after cataract surgery with an intraoperative pars plana intravitreal antibiotic-steroid (IVAS) injection of triamcinolone, moxifloxacin, and vancomycin (TMV) versus a standard postoperative topical regimen. Patients and Methods A retrospective comparative case series of 1058 eyes (control = 487, treatment = 571) undergoing cataract surgery were included. Endpoints included best-corrected visual acuity (BCVA), intraocular pressure (IOP), and the unplanned use of anti-inflammatory topical medication in the postoperative period. The follow-up period ranged from 1 to 6 months. Results A final monocular BCVA of 20/25 or better was achieved in 78.8% and 87.4% of eyes in the control and treatment groups, respectively (p = 0.001). The overall incidence of an IOP spike (Δ ≥ 10 mm Hg) was not significantly different between the two groups (0.4% versus 1.9%, p = 0.027). The rates of persistent anterior chamber inflammation (PACI), rebound anterior chamber inflammation (RACI), and cystoid macular edema (CME) in the control and treatment groups were 8.0% vs 2.6% (p < 0.001), 6.4% vs 2.6% (p = 0.003), and 3.9% vs 4.7% (p = 0.511), respectively. The use of an IVAS injection of TMV conferred an increased risk of CME (odds ratio [OR] = 3.21, 95% confidence interval [CI] = 1.42 to 7.23) but no significant effect on the risk of PACI (OR = 0.34, 95% CI = 0.10 to 1.14) or RACI (OR = 0.52, 95% CI = 0.18 to 1.54) when compared to a topical regimen. Conclusion An intraoperative IVAS injection after uncomplicated cataract surgery may be as safe and effective as a standard topical regimen in terms of postoperative IOP and anterior chamber inflammatory events, respectively. However, the efficacy of a TMV formulation for CME prophylaxis appears to be unsatisfactory. Future studies with prospective and randomized designs are needed to further evaluate this technique.

Comparative analysis of intravitreal triamcinolone acetonide-moxifloxacin versus standard perioperative eyedrops in cataract surgery. J Cataract Refract Surg 2019; 45:760-765. [PMID: 30850125 DOI: 10.1016/j.jcrs.2018.12.019] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 12/13/2018] [Accepted: 12/14/2018] [Indexed: 11/23/2022]
Abstract
PURPOSE To compare the effectiveness of intravitreal injection of triamcinolone acetonide-moxifloxacin (Tri-Moxi) to a standard eyedrop regimen in controlling postoperative inflammation, corneal edema, and the rate of high intraocular pressure (IOP) among cataract patients. SETTING Loma Linda University Eye Institute, California, USA. DESIGN Retrospective longitudinal comparative study. METHODS The electronic medical records of patients who underwent cataract surgery using triamcinolone acetonide-moxifloxacin injection along with a postoperative nonsteroidal antiinflammatory drug drop were reviewed (Group 1). Group 1 was compared with patients who received a standard eyedrop (Group 2) in terms of intraocular inflammation and corneal edema severity, and the rate of high IOP, postoperatively. RESULTS A total of 1195 consecutive eyes (Group 1 [681 eyes], Group 2 [514 eyes]) of 919 patients were included in the study. The anterior chamber cell reaction severity decreased by 34.0% and 35.7% at 1 week and 1 month, respectively, after surgery following triamcinolone acetonide-moxifloxacin injection compared with standard eyedrop therapy (P = .001 and P = .02, respectively). Group 1 was associated with increased severity of corneal edema (odds ratio, 1.48; P = .001) on postoperative day 1, with no statistically significant difference at 1 week and 1 month postoperatively (P = .25 and P = .48, respectively). There was no statistically significant difference in the rate of high IOP between the two groups at different timepoints postoperatively. CONCLUSIONS Triamcinolone acetonide-moxifloxacin injection is an effective method to control intraocular inflammation after cataract surgery. It is a promising substitute for standard eyedrop therapy, especially for patients who have poor compliance with eyedrop usage.

Abstract
Purpose: To report the laboratory findings, management strategies, and visual outcomes of culture-proven exogenous fungal endophthalmitis in North China. Methods: The microbiological and treatment records of patients with culture-positive exogenous fungal endophthalmitis who visited the Affiliated Hospital of Qingdao University from January 2012 to December 2016 were reviewed. Results: A total of 39 eyes (39 patients) were identified over a 5-year period. Exogenous fungal endophthalmitis was associated with penetrating trauma in 22 eyes (56.4%), fungal keratitis in 15 eyes (38.5%), and intraocular surgery in 2 eyes (5.1%). Hyphae were found in 29 of 37 smear samples (78.4%) by direct microscopic examination. Fungal pathogens cultured from 39 samples were identified as 10 genera and 15 species. Filamentous fungi (molds) accounted for 94.9% (37 samples), including Fusarium (19, 48.7%) and Aspergillus (11, 28.2%). Most keratitis cases were caused by Fusarium (11 of 15; 73.3 %). Aspergillus was isolated from nine penetrating ocular trauma cases (9 of 22; 40.9%). Three eyes receiving evisceration had fungal and bacteria coinfection (3 of 39, 7.7%) with Aspergillus and Bacillus. At least, one surgical intervention was performed in all 39 eyes and 28 (71.8%) eyes underwent two or more procedures, including surgeries and intraocular injections. Twenty-nine patients received intraocular antifungal therapy with amphotericin B and/or voriconazole. Visual acuity at discharge from the hospital was significantly better than the initial visual acuity ( p < 0.001). Final vision of 20/400 or better was achieved in 22 (56.4%) eyes. Conclusions: This study highlighted the differences between clinical categories of exogenous fungal endophthalmitis. Trauma was the major etiological factor. Molds were the most common pathogens, with Fusarium ranking first, followed by Aspergillus. Fungal and bacterial coinfection mostly occurred after metal penetrating trauma, and Bacillus was the primary bacterial pathogen. Coinfection may be one reason of evisceration. Immediate intravitreal antifungal therapy combined with vitrectomy was effective for exogenous fungal endophthalmitis. Amphotericin B and voriconazole were commonly used antifungal agents.

Abstract
PURPOSE To evaluate the safety and efficacy of intracameral (IC) 0.5% moxifloxacin in the prevention of post-cataract endophthalmitis. SETTING University of Campinas, São Paulo, Brazil. DESIGN Prospective randomized partially masked single-site clinical trial. METHODS Patients who had phacoemulsification were randomized into two groups in block sizes of 4. Group A (moxifloxacin group) consisted of patients who received an IC injection of 0.03 mL (150 μg) of undiluted 0.5% moxifloxacin at the end of surgery. Group B (control group) consisted of patients who received no IC medication. The postoperative prescription for both groups consisted of 0.5% moxifloxacin and 0.1% dexamethasone. Patients were monitored for 6 weeks after surgery. The primary outcome was the incidence of acute endophthalmitis in each group. Secondary outcomes were corrected distance visual acuity (CDVA), endothelial cell density (ECD), intraocular pressure (IOP), and central corneal thickness (CCT). RESULTS The study comprised 3640 eyes from 3640 patients. There were 1818 patients in Group A and 1822 patients in Group B. The incidence of endophthalmitis within 6 weeks of follow-up was 1 (0.05%) of 1818 eyes in the moxifloxacin group and 7 (0.38%) of 1822 eyes in the control group (P = .035). There was no significant difference in CDVA (P = .202), ECD (P = .482), IOP (P = .105), or CCT (P = .558). No ocular or systemic study-related adverse events were observed. CONCLUSIONS The IC injection of undiluted 0.5% moxifloxacin can be safely applied as the last step of phacoemulsification. It was found to be effective in reducing the risk for endophthalmitis. This study represents the first controlled randomized clinical trial to evaluate the safety and efficacy of IC moxifloxacin in the prevention of post-cataract endophthalmitis.

Abstract
Post-operative endophthalmitis (POE) following cataract surgery is an uncommon, vision-threatening complication that has been reported to occur at rates of between approximately 0.03% and 0.2%. Prompt diagnosis and treatment of endophthalmitis is critical for minimizing vision loss, but most recent efforts have focused on the prophylactic administration of antibiotics to prevent the development of endophthalmitis. Surgeons from around the world have different topical and intracameral antibiotic usage patterns to prevent endophthalmitis, and to date no general consensus regarding best practice has emerged. Several studies have reported on the routine use of intracameral cefuroxime, moxifloxacin, and vancomycin, including a single randomized clinical trial by the European Society of Cataract and Refractive Surgery (ESCRS) in 2007. These studies have notable shortcomings, but many authors suggest that intracameral cefuroxime together with topical antibiotics probably decreases the risk of endophthalmitis. However, the deleterious effects of routine prophylactic antibiotics, which include toxicity, cost, and increasing antimicrobial resistance, among others, are noteworthy. In contrast, aseptic technique with pre-operative instillation of povidone-iodine remains the only technique supported by level I evidence to reduce the incidence of endophthalmitis. Although the routine use of intracameral antibiotics continues to increase throughout the world, data from multicenter, randomized, prospective trials is needed to provide better guidance regarding the prophylactic use of antibiotics.

Abstract
Background Intracameral cefuroxime is recommended as prophylaxis against postoperative endophthalmitis (POE) following cataract surgery. Aprokam is the only licensed product for prophylaxis of POE, although unlicensed intracameral cefuroxime may be administered using pre-filled syringes (PFS), either prepared in hospital by reconstituting cefuroxime via serial dilution (prepared PFS), or commercially purchased (purchased PFS). This study aimed to estimate the potential budget impact of using Aprokam over unlicensed cefuroxime for intracameral administration. Methods A budget impact model (BIM) was developed from UK NHS hospital perspective to estimate the economic impact of adopting Aprokam compared with purchased PFS or prepared PFS for the prophylaxis of POE following cataract surgery over a 5-year time horizon. The BIM incorporated direct costs only, associated with the acquisition, delivery, storage, preparation, and administration of cefuroxime. Resource utilisation costs were also incorporated; resource utilisation was sourced from a panel survey of hospital pharmacists, surgeons, and theatre nurses who are involved in the delivery, storage, preparation, quality assurance, or administration of cefuroxime formulations. Unit costs were sourced from NHS sources; drug acquisition costs were sourced from BNF. The model base case used a hypothetical cohort comprising of 1000 surgeries in the first year and followed a 5.2 % annual increase each year. Results The model predicts Aprokam is cost saving compared with purchased PFS, with a modest increase compared prepared PFS over 5 years. There are total savings of £3490 with Aprokam compared with purchased PFS, driven by savings in staff costs that offset greater drug acquisition costs. Compared with prepared PFS, there are greater drug acquisition costs which drive an increased total cost over 5 years of £13,177 with Aprokam, although there are substantial savings in staff costs as well as consumables and equipment costs. Conclusions The lower direct costs of using Aprokam compared with purchased PFS presents a strong argument for the adoption of Aprokam where purchased PFS is administered. The additional benefits of Aprokam include increased liability coverage and possible reduction in dilution errors and contaminations; as such, in hospitals where unlicensed prepared PFS is used, modest additional resources should be allocated to adoption of Aprokam.

Abstract
Abstract
Fungi rarely cause disease outbreaks associated with use of microbe-contaminated drugs. These rare episodes typically involve a restricted spectrum of common environmental species with relatively low virulence, rather than classical pathogens. Review of data involving over-the-counter contact lens solutions and prescription drug-related recalls revealed six episodes during the past decade with significant adverse health and financial impact (including loss of vision and death). Contaminations involved fungi mostly identified with the genera Aspergillus, Exserohilum, Fusarium, Paecilomyces, and Rhizopus. These organisms are noted for their capacity to produce resistant morphotypes (chlamydoconidia, ascospores) under various adverse conditions, generally with temperature survival/tolerances markedly in excess of maximal growth temperatures. High constituent levels of melanin, trehalose and heat-shock proteins facilitate differential survival of morphotypes following exposures to toxic chemicals and temperatures above 80 °C. Adverse environmental factors that induce resistant morphotypes are suggested to occur more readily in situ than during in vitro testing. Rare unexplained, sporadic drug contamination episodes with select thermotolerant fungi may relate, in part, to resistant dormant stages.

Abstract
Fusarium is considered an emerging pathogen, and there are few reports of fusariosis in children. The objective of this study was to describe an outbreak of invasive fusariosis in a children's cancer hospital. A neutropenic 17-year-old male patient hospitalized for 10 days for a relapse of acute myeloid leukaemia, under chemotherapy, presented fever without any other symptoms; a thoracic computerized tomography showed bilateral pulmonary nodules. During voriconazole treatment, 1-cm reddened and painful subcutaneous nodules appeared on arms and legs and the culture of a skin biopsy revealed F. solani. Another case occurred 11 days later and started an outbreak investigation. Water samples for cultures were collected from taps, showers and water reservoirs. Air from all patient rooms was sampled. Faucets and the drains of sinks and showers were swabbed and cultured. Environmental and clinical isolates were typed. There were 10 confirmed cases of infection caused by Fusarium spp. F. oxysporum and F. solani were isolated from water, swabs and air in patient rooms. Many control measures were instituted, but the outbreak was only controlled 1 year after the first case, when water filters filtering 0.2 μm were installed at the exit of all faucets and showers in all patient rooms (points-of-use). Typing demonstrated that clinical isolates of F. oxysporum were similar to those of the environment. In conclusion, to our knowledge this is the first reported outbreak of invasive fusariosis in children with oncohaematologic disease. It was controlled using 0.2-μm filters in all tap faucets and showers.

Rahman N, Murphy CC. Impact of intracameral cefuroxime on the incidence of postoperative endophthalmitis following cataract surgery in Ireland. Ir J Med Sci 2014; 184:395-8.

Abstract
BACKGROUND Postoperative endophthalmitis (PE) is a rare complication of cataract surgery, but carries a significant risk of blindness. The European Society of Cataract and Refractive Surgeons published a landmark study in 2007 that revealed the use of intracameral cefuroxime as prophylaxis against endophthalmitis reduced its incidence by fivefold. Since the publication of these results, the use of intracameral cefuroxime in cataract surgery has become a standard practice in many institutions, including our own. AIM To identify the incidence rate of PE among patients undergoing cataract surgery over the 4-year period following the introduction of prophylactic intracameral cefuroxime for cataract surgery. METHODS A retrospective case note review of all cases of postoperative endophthalmitis that occurred between 2007 and 2011 was performed. Our results were compared with an earlier report on PE incidence rates from our institution that was conducted prior to the introduction of intracameral cefuroxime and published in 2001. RESULTS There were five reported cases of endophthalmitis from 2007 to 2011 from a total of 8,239 cataract procedures, giving an incidence rate of 0.06%. This compares with an incidence rate of 0.49% in the earlier study prior to the introduction of intracameral cefuroxime and represents an eightfold reduction in the incidence of PE at our hospital. Of the five cases, three were confirmed on culture and sensitivity (two of which were due to Coagulase negative staphylococci and one due to Pseudomonas aeruginosa). CONCLUSION The incidence of postoperative endophthalmitis has reduced by approximately eightfold since the introduction of intracameral cefuroxime following cataract surgery at our hospital in 2007. This study strongly supports the use of intracameral cefuroxime as prophylaxis against endophthalmitis in all cataract surgical cases.

Abstract
Outbreak of exogenous Fusarium endophthalmitis after cataract surgery was evaluated. Twenty patients developed postoperative endophthalmitis. In 19 eyes, pars plana vitrectomy (PPV) was performed, in 14 cases (74 %) with primary intraocular lens explantation. In one case, the PPV was not performed because of poor general condition of the patient. Symptoms of endophthalmitis (damaged vision, iritis, tyndallization in anterior chamber, hypopyon) occurred at intervals of 16-79 days (mean 31.3 days). Fungal etiology was documented in 12 eyes (60 %). Fusarium oxysporum was evidenced by culture and/or microscopy and confirmed by PCR and sequencing analysis. Eighteen (90 %) patients were treated with oral voriconazole (400 mg/day) for a period of 4-6 weeks. The final visual acuity was 6/15 in 1 case (5 %), 6/60 and worse in 17 eyes (85 %), and in 2 cases (10 %), enucleation had to be performed. Viscoelastic filling material was suggested the most likely source of infection. Endophthalmitis caused by Fusarium spp. are a potentially big threat for patients with serious impact on vision. Successful management of the infection is highly dependent on early diagnosis including species identification and antifungal susceptibility testing, and on aggressive and long-term treatment.

The efficacy of voriconazole in 24 ocular Fusarium infections. Infection 2012; 41:15-20.

Abstract
PURPOSE We examined, retrospectively, the efficacy of voriconazole in Fusarium eye infections. METHODS Voriconazole-treated patients with proven or probable keratitis or endophthalmitis from the voriconazole database (9 patients) and six French ophthalmology departments (15 patients) were included. Sociodemographic features, predisposing factors, history of corneal trauma, associated ocular conditions, other diseases and prior therapies were analysed. Investigator-determined success was defined as infection resolution with medical treatment. Failure was no response or persistent infection and required surgery. RESULTS Most patients were Caucasian (83 %) and male (71 %). The infection was keratitis (63 %) or endophthalmitis (37 %) and proven in 23 (96 %). Prior therapy included topical and/or systemic amphotericin (46 %), fluconazole (17 %) or others (33 %), often in combination. Causative fungi were Fusarium solani (14, 58 %), Fusarium moniliforme (1), Fusarium oxysporum (1) and Fusarium spp. (8). Voriconazole was administered systemically, topically and/or by intraocular injection, and 16 patients (67 %) received salvage and eight primary therapy. The overall response was 67 % (73 % keratitis and 56 % endophthalmitis) but seven patients required adjunctive surgery. However, response was 63 % for eight primary therapy patients and 69 % for 16 salvage therapy patients. Response by species was Fusarium solani 64 % (9/14) and all others 80 % (8/10). In 13 patients (77 %), voriconazole was used in combination (response 69 vs. 64 % alone) with topical [amphotericin B 10/24 (42 %), caspofungin 5 (21 %), natamycin 1 (4 %)] and systemic agents [caspofungin 3 (13 %), amphotericin 2 (8 %)]. CONCLUSIONS Topical and systemic voriconazole appears to be effective alone or in combination with other agents for treating severe Fusarium keratitis or endophthalmitis.

Abstract
Fungi can cause severe infections. Two or more nosocomial unusual fungal infections diagnosed in a short period should be assumed as an outbreak. The review's aim was to collect data to improve their management. The free online worldwide database for nosocomial outbreaks ( http://www.outbreak-database.com ) and the PubMed/MEDLINE database were used to collect the English literature published from 1990 to June 2011. The more common Candida spp. and Aspergillus spp. infections were excluded. For each outbreak, the following data were reviewed: species, duration, source and site of infection, ward, risk factors, number of patients infected, treatment, related mortality, type of epidemiological study and time elapsed between index cases and second cases. Thirty-six reports were considered: yeasts caused the majority of the outbreaks (16 out of 36). The median values for the overall duration, number of infected people per outbreak and infection-related mortality were 5 months, 4 and 20 %, respectively. Eighteen cases were caused by contaminated substances and 13 cases were hypothesised as human-transmitted. Nosocomial outbreaks due to rare fungal pathogens involve few patients but have high related mortality. These results could be explained by the diagnostic delay, the inability of recognising the source of the infections and the challenges of the treatment. More efforts should be concentrated to implement the application of proper hygiene practices to avoid human-human transmission.

Abstract
To report an outbreak of Fusarium solani endophthalmitis after uneventful cataract surgeries performed on the same day in the same operating room. Nine patients underwent phacoemulsification at 4th Clinic of Beyoglu Eye Training and Research Hospital in Istanbul. Cefuroxime axetyl was injected intracamerally from the same vial to all patients at the end of surgery. All patients developed acute postoperative endophthalmitis. Presentation, cultural studies, treatment, clinical responses and risk factors were evaluated. Cultural and DNA sequence findings revealed F. solani. Antifungal therapy was begun and pars plana vitrectomy, intraocular lens and capsule extraction were performed. Corneal involvement was correlated with old age and systemic disease. Fusarium solani should be considered in acute postoperative endophthalmitis. This infection can be controlled with early and aggressive combined antifungal and surgical treatment. The patients with corneal involvement had poor prognosis. It is important to use solutions prepared separately for each patient.
