Summary
A recurrent orbital abscess in a patient with cardiofaciocutaneous syndrome was linked to Morganella morganii originating from the lacrimal sac. This case highlights the importance of identifying uncommon bacteria in orbital infections and their antibiotic sensitivities.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Genetics
Background:
- Cardiofaciocutaneous syndrome (CFC) is a rare genetic disorder associated with developmental abnormalities.
- Orbital abscesses can arise from various sources, including hematogenous spread and local infections.
- Recurrent orbital infections necessitate thorough investigation into underlying causes and causative pathogens.
Observation:
- A 22-year-old female with CFC presented with a recurrent orbital abscess.
- Intraoperative examination revealed direct extension of the abscess from the lacrimal sac (dacryocystitis).
- Cultures identified Morganella morganii, a Gram-negative rod rarely implicated in ocular infections.
Findings:
- Morganella morganii was the causative agent of the recurrent orbital abscess.
- This represents one of the few reported cases of orbital abscess caused by this specific bacterium.
- The infection's origin was traced to dacryocystitis, not hematogenous spread.
Implications:
- Accurate identification of the causative organism and antibiotic sensitivity testing are crucial for managing orbital abscesses.
- Dacryocystitis should be considered as a potential source of orbital infections, especially in recurrent cases.
- This case expands the understanding of potential pathogens in orbital infections, particularly in immunocompromised or syndromic patients.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Microbiome 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...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:25Glaucoma: 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...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
