Klebsiella pneumoniae liver abscess has a tendency to spread to distant sites early in the course of disease and to involve multiple organs synchronously. A 59-year-old male was admitted because of liver abscess accompanied by fever and abdominal pain. The patient underwent percutaneous catheter drainage and received intravenous antibiotics. Symptom relief was achieved after the treatment as well as marked reduction in the size of the abscess. Despite proper treatment of the liver abscess, however, patient developed multiple metastatic infections in a non-concurrent manner: left and right endophthalmitis, psoas abscess, and infectious spondylitis at 5, 23, 30 and 65 days after initial manifestations of liver abscess, respectively. Each infectious episode followed one another after resolution of the former one. For each episode of metastatic infections, the patient promptly underwent treatment with systemic and local antibiotics, interventional abscess drainage, and surgical treatments as needed. The patient fully recovered without sequelae after the use of intravenous antibiotics for an extended period of time. Herein, we report a case of K. pneumoniae liver abscess complicated with delayed-onset multiple metastatic infections.

A 58-year-old man admitted to our opthalmology department with the complaint of branch retinal vein occlusion. He was treated with intravitreal Ozurdex in the right eye. Two days after the injection, the patient presented with ocular pain and the visual acuity was hand movement. A diagnosis of endophthalmitis was made. We performed emergent pars plana vitrectomy (PPV) and the implant was removed from the vitreous cavity using a retinal forceps. A combination of vancomycin 1.0 mg and amikacin 0.4 mg was injected intravitreally. However, because of the blurring in the vitreus one week after the procedure, phacoemulsification and a repeat PPV was performed. Five days after the last procedure the signs and symptoms of endophthalmitis were resolved. Our case demonstrated that endophthalmitis could develop after intravitreal implantation of Ozurdex. Surgical removal of the implant and immediate vitrectomy seems to be a useful treatment option in these cases.

BACKGROUNDNon-infectious endophthalmitis was reported to occur after cataract surgery or intravitreal injections. This study reported a series of patients having non-infectious endophthalmitis after pars plana vitrectomy in the same two operation rooms during the same period to estimate the risk factors for non-infectious endophthalmitis after vitrectomy.

METHODSMedical records of patients who presented with severe non-infectious endophthalmitis following vitrectomy between May 13 and June 8, 2011, were reviewed. The presenting symptoms and signs were collected, including visual acuity, intraocular pressure, cornea and anterior chamber activity. The treatments and results of microbiology examination were also recorded and analyzed.

RESULTSTen patients were identified with severe non-infectious endophthalmitis, presenting 1 day after pars plana vitrectomy. Three eyes (30%) had previous intraocular surgeries, four (40%) had proliferative diabetic retinopathy, and one (10%) got pars plana vitrectomy combined with phacoemulsification and intraocular lens implantation. All the patients were initially treated with topical and/or oral steroids. Only two patients had intravenous antibiotics because of the atypical presentation. One eye had paracentesis because of high intraocular pressure and the aqueous sample was sent for microbiological examination. The culture of the aqueous, air in the operation room, the swab from hand of surgeons, infusion fluid, and vitrectomy effluent were all negative for bacteria and fungi. The inflammation regressed rapidly after the initial treatment.

CONCLUSIONSIntraocular surgery history, poor general health status, longer operation time, and more surgical procedures are the risk factors for non-infectious endophthalmitis after vitrectomy. It responds well to steroids.

BACKGROUNDEndophthalmitis can be a devastating complication after pars plana vitrectomy. The incidence of postvitrectomy endophthalmitis is significantly lower than that of endophthalmitis occurring after other intraocular operations. However, normal post-operative pain and inflammation may mask endophthalmitis and lead to delayed diagnosis and grave visual consequences. This study aimed to summarize the outcomes of cases that underwent pars plana vitrectomy over a 10-year period and to analyze the characteristics of post-vitrectomy endophthalmitis.

METHODSA retrospective observational case study was conducted on all the cases who underwent pars plana vitrectomy in the Beijing Tongren Hospital between January 1, 2002 and March 31, 2012. All cases of endophthalmitis that occurred during a period of 10 years and 3 months were reviewed, and the possible risk factors, clinical findings, causative organism(s), and the sources of infection were analyzed.

RESULTSWithin the 10-year observational period, 14 patients developed endophthalmitis after pars plana vitrectomy. The incidence of post-vitrectomy endophthalmitis (0.05%) was lower than that reported previously from the same center (0.12%). Staphylococcus epidermidis (five patients, 35.71%) was the most common organism identified in aqueous or vitreous cultures. Eight patients (57.14%) had diabetes mellitus. There was no statistically significant difference (P > 0.05) in the incidence of endophthalmitis between period 1 (with antibiotic pretreatment) and period 2 (without antibiotic pretreatment). Surgical procedures for the treatment of endophthalmitis were performed in 10 patients (71.43%).

CONCLUSIONSThis series of cases showed that the incidence of endophthalmitis after pars plana vitrectomy is lower than what was previously reported in our hospital. A variable degree of corneal edema with relatively normal or mildly increased intraocular pressure was one of the commonly observed characteristics of post-vitrectomy endophthalmitis. Staph. epidermidis was the most common causative organism, and antibiotic pretreatment did not lower the incidence of postvitrectomy endophthalmitis.

PURPOSE: Postoperative endophthalmitis is a dreaded outcome of any intraocular surgery. Fungal endophthalmitis is a particularly severe complication that poses a significant threat of blindness. We experienced seven consecutive cases of postoperative fungal endophthalmitis stemming from a single local clinic in which extensive early intervention resulted in favorable final visual acuity. METHODS: The present study is retrospective observational case series of fungal endophthalmitis. The initial case, as diagnosed by fungal culture, resulted in blindness. In the ensuing eight months, seven consecutive cases were referred to our institution. All were presumed to be fungal endophthalmitis as the cases possessed similar inflammatory findings to the preceding case and occurred in the same environment. Extensive surgical and antifungal treatment was immediately administered, including complete vitrectomy with removal of the intraocular lens and lens capsule and Amphotericin B injections. RESULTS: Retinal infiltration was identified in three cases and the lesion site was photocoagulated with an endolaser. All cases were confirmed fungal endophthalmitis by culture (4 cases: Candida parapsilosis, one case each: Fusarium, Acremonium, Candida tropicalis) and five cases required secondary intraocular lens implantation. Final corrected visual acuity ranged from 20/20 to 40/200 by the Snellen chart. CONCLUSIONS: Early extensive surgical intervention and antifungal agent administration may result in favorable visual outcomes in patients with fungal endophthalmitis following cataract surgery.
