Insights

This case study highlights a rare instance of facial cellulitis caused by Pseudomonas aeruginosa, a Gram-negative bacillus. This infection complicated ophthalmic herpes zoster in a diabetic patient, emphasizing the need for prompt recognition and management of such severe soft-tissue infections.

Area of Science:

  • Dermatology
  • Infectious Diseases

Background:

  • Facial cellulitis is a severe soft-tissue infection with common entry points including head and neck surgery, dental infections, and trauma.
  • Prompt recognition and management are crucial to prevent severe complications.

Observation:

  • A 74-year-old woman with ophthalmic herpes zoster and diabetes developed facial cellulitis.
  • Skin swabs revealed Pseudomonas aeruginosa, a Gram-negative bacillus, as the causative agent.
  • Treatment involved intravenous ciprofloxacin, daily drainage, and topical fusidic acid.

Findings:

  • The facial cellulitis caused by Pseudomonas aeruginosa completely resolved within 4 weeks.
  • No general complications or recurrence were observed during a 6-month follow-up.
  • This represents a rare occurrence of Pseudomonas aeruginosa in facial cellulitis, especially as a complication of ophthalmic herpes zoster.

Implications:

  • Herpetic damage and impaired immune defense in diabetic patients may predispose to opportunistic infections like this.
  • This case underscores the importance of considering unusual pathogens in facial cellulitis, particularly in immunocompromised individuals.
  • Early diagnosis and appropriate antibiotic therapy are vital for successful outcomes in complex cellulitis cases.

Chickenpox01:20

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
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...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Herpes01:28

Herpes

Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Brain Abscess l: Introduction01:26

Brain 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,...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
