A 56-year-old man with chief complaints of reduced visual acuity in the left eye and an 8-day history of pyrexia was diagnosed with uveitis at a nearby hospital, and was referred and admitted to our hospital. Two days after admission, he complained of dyspnea. Chest X-ray revealed an infiltrative shadow in the right middle pulmonary field and right pleural effusion. Chest CT revealed multiple peripheral nodules and a wedge-shaped shadow with a cavity and feeding vessel. Klebsiella pneumoniae was isolated from the blood, and he was diagnosed with septic pulmonary embolism. In addition, ciliary injection and hypopyon of the right eye were recognized, and he was therefore diagnosed with endogenous endophthalmitis due to sepsis. With antibacterial therapy, the symptoms, imaging findings, and inflammatory reaction inproved, but visual acuity did not. This was a rare case of septic pulmonary embolism accompanied by endogenous endophthalmitis.

Coagulase-negative staphylococci (CNS) are normal inhabitants of human skin and mucous membranes. They have long been dismissed as culture contaminants, but now the potentially important role of CNS as pathogens and their increasing incidence has been recognized. Approximately 55-75% of nosocomial isolates is methicillin resistant. CNS were the first organisms in which glycopeptide resistance was recognized. In the immunocompetent host, CNS endocarditis and urinary tract infections with Staphylococcus saprophyticus are the most common CNS infections. Other patients are usually immunocompromised, with indwelling or implanted foreign bodies. CNS account for approximately 30% of all nosocomial blood stream infections. The majority of these concern catheter-related sepsis. Other important infections due to CNS include central nervous system shunt infections, endophthalmitis, surgical site infections, peritonitis in patients with continuous ambulatory peritoneal dialysis and foreign body infections. CNS are rarely associated with mastitis in humans. Staphylococcus lugdunensis is more pathogenic than other CNS as it expresses several potential virulence factors. The distinction between clinically significant, pathogenic and contaminating isolates is a major problem. Several studies show clonal intra and inter hospital spread of Staphylococcus epidermidis strains which suggests that infection control measures may be necessary for multiresistant CNS isolates as for methicillin resistant Staphylococcus aureus. As a result of medical progress, mainly due to the use of invasive and indwelling medical devices, CNS are now a major cause of nosocomial and health-care related infections.

A neonate with an estimated gestational age of 32 weeks who had post-partum sepsis (methicillin-resistant Staphylococcus aureus [MRSA] and Pseudomonas aeruginosa) and MRSA meningitis was found to have blunted light reflexes and microphthalmia in both eyes on routine screening for retinopathy of prematurity. Retrolenticular membranes precluded visualization of the fundi. Computed tomography confirmed the presence of intraocular calcifications, an interval development over 6 weeks from previously normal scans. Referral was made and diagnostic enucleation of the right eye was performed, revealing intraocular disorganization and metaplasia consistent with phthisis following intraocular inflammation. The patient's contralateral eye achieved visual acuity of light perception after lensectomy and vitrectomy. Vitreous cultures from the enucleation specimen and from the fellow eye at the time of vitrectomy were negative. Unsuspected, untreated endogenous endophthalmitis can result in dramatic and rapid metaplastic response in the developing eye and result in acute phthisis.

A diabetic woman suffered from deep neck infection, endophthalmitis, urinary tract infection, and mycotic aneurysm associated Klebsiella pneumoniae bacteremia for 4 months. Aneurysmectomy and antibiotic therapy terminated recurrent K pneumoniae sepsis suggestive of removal of the pathogen niche in an artery, which served as the root of serial infections. The DNA fingerprints of K pneumoniae isolates indicated that the same strain K pneumoniae caused all the infection episodes. The case is reported and its clinical implications are discussed.

Group B streptococcus (GBS) is a potentially devastating neonatal pathogen that most commonly causes meningitis, sepsis, and pneumonia. It is also a very rare cause of endogenous endophthalmitis. We present the second case of endogenous endophthalmitis caused by GBS in a healthy newborn and the first case of endogenous endophthalmitis by GBS in a newborn mimicking retinoblastoma and resulting in enucleation.

Pyogenic liver abscess (PLA) is still associated with significant morbidity and mortality. With advances in imaging, most cases are now diagnosed early and effectively treated. However, complications, although considered rare, may still occur. We report three cases of PLA that were associated with rare and significant complications. Two patients had an abscess rupture that resulted in pyopericardium in one patient and sub-diaphragmatic abscess in the other. Another patient with Klebsiella pneumoniae PLA had bilateral endophthalmitis that resulted in blindness. Death secondary to overwhelming sepsis occurred in the patient with Escherichia coli-related pyopericardium. Delay in diagnosis contributed to the complications in two of the patients.

Invasive fungal infections (IFI) and fungal sepsis in the intensive care unit are increasing and are associated with considerable morbidity and mortality. In this setting, IFI are predominantly caused by Candida species. Outcomes continue to be suboptimal; however, there are a few key clinician modifiable factors. PK-PD studies with the approved antifungal agents have provided guidance on the dosing strategy that predicts improved outcome. In addition, time to therapy is a critical element. Therefore early recognition through improved risk factor analysis and diagnostics will be key developments. Source control for infected devices and endophthalmitis must be considered.

Endogenous bacterial endophthalmitis, also called metastatic bacterial endophthalmitis, remains a diagnostic and therapeutic challenge. It is a rare and potentially sight-threatening ocular infection that occurs when bacteria reach the eye via the bloodstream, cross the blood-ocular barrier, and multiply within the eye. It usually affects immunocompromised patients and those suffering from diabetes mellitus, malignancy, or cardiac disease, but has also been reported after invasive procedures or in previously healthy people. In most cases, the ocular symptoms occur after the diagnosis of septicemia or systemic infection. Ocular symptoms include decreased vision, redness, discharge, pain, and floaters. The ocular inflammatory signs may be anterior and/or posterior. Bilateral involvement occurs in nearly 25% of cases. A wide range of microorganisms are involved, with differences in their frequency according to geography as well as the patient's age and past medical history, because of variations in the predisposing conditions and the source of the sepsis. The majority of patients are initially misdiagnosed, and ophthalmologists should be aware of this because prompt local and general management is required to save the eye and/or the patient's life.

A total of 32 Staphylococcus epidermidis isolates from indwelling device-related infections such as endophthalmitis following intraocular lens (IOL) implantation, intravenous catheter-related sepsis and orthopaedic implant infections, were studied for slime production and adherence to artificial surfaces. Of these, 21 (65.6%) isolates were slime positive by the Congo Red agar method and 24 (75%) were adherent to artificial surfaces by the quantitative slime test. The majority (19 out of 24; 79.1%) of the adherent bacteria were slime producers. Antibody to slime raised in rabbits was able to inhibit the adherence of all 24 bacteria designated as adherent by our quantitative test. It seems that slime is indispensable for the sessile mode of attachment, leading further to the development of biofilms on the indwelling devices.

Endogenous endophthalmitis is a rare but potentially blinding complication of neonatal sepsis. Early diagnosis and aggressive treatment are essential to avoid vision loss. Therapeutic options include systemic and intravitreal antibiotics, as well as vitrectomy in selected cases. We report a series of 6 premature very low birth weight neonates who developed endogenous endophthalmitis in our NICU over the past 3 years. Endophthalmitis was part of early-onset sepsis in 2 newborns, both of whom died, and late-onset sepsis in 4 newborns, of which 1 infant died. None of the neonates had any history of previous trauma or intervention to the eye. Maternal screening for congenital infections, including HIV, was negative in all. Causative organisms included Klebsiella pneumoniae (2 cases), Pseudomonas aeruginosa (2 cases), Methicillin-resistant Staphylococcus aureus (1 case), and Candida albicans (1 case). All bacterial isolates showed resistance to first-line antibiotics. Of the 3 survivors, 2 infants had normal vision in the affected eye, and 1 developed phthisis bulbi after corneal perforation and required enucleation. This report draws attention to the emergence of endophthalmitis as a complication of neonatal sepsis in places where, although survival of very low birth weight newborns has increased significantly due to improved care, the burden of infection continues to be high. We emphasize the importance of daily examination of eyes as a part of routine clinical care in septic newborns for early diagnosis of endophthalmitis and prompt intervention in consultation with an ophthalmologist to optimize the outcome.
