Insights

Three patients developed endophthalmitis after cataract surgery due to Rhizobium radiobacter. Bacterial DNA detection aided early diagnosis, and all patients recovered, though two required vitrectomy.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Post-cataractic endophthalmitis is a severe intraocular infection.
  • Rhizobium radiobacter is an uncommon cause of endophthalmitis.

Observation:

  • Three distinct cases of endophthalmitis occurred in patients who had undergone cataract surgery.
  • The causative agent identified in all three cases was Rhizobium radiobacter.
  • These cases were unrelated and occurred in separate hospital settings.

Findings:

  • Early diagnosis was achieved in two out of three patients through the detection of bacterial DNA in vitreous humor samples.
  • All three patients successfully recovered from the infection.
  • Two patients experienced rapid clinical deterioration necessitating pars plana vitrectomy.

Implications:

  • Rhizobium radiobacter should be considered as a potential pathogen in post-cataract surgery endophthalmitis.
  • Bacterial DNA detection in vitreous samples can facilitate prompt diagnosis and management.
  • Aggressive management, including pars plana vitrectomy, may be required in severe cases.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
