Abstract

Insights

Meningococcaemia-related purpura fulminans in children has a 10.7% mortality. Early surgical intervention, including skin-releasing incisions and delayed skin grafting for extensive necrosis, improves extremity salvage outcomes.

Area of Science:

  • Pediatric Surgery
  • Infectious Diseases
  • Wound Healing

Background:

  • Meningococcaemia can lead to purpura fulminans, a severe condition causing skin necrosis.
  • Effective management strategies are crucial for improving patient outcomes.

Purpose of the Study:

  • To detail surgical management of purpura fulminans secondary to meningococcaemia.
  • To propose a protocol for managing this condition.

Main Methods:

  • Retrospective review of 112 children with purpura fulminans admitted to intensive care.
  • Analysis of treatment, including wound care, skin grafting, and amputation.

Main Results:

  • Overall mortality was 10.7%.
  • Average skin necrosis was 14% of total body surface area, predominantly affecting lower limbs.
  • 77% of patients required skin grafting; 31.2% resolved without necrosis.

Conclusions:

  • Meningococcaemia-associated purpura fulminans has severe consequences requiring prompt surgical evaluation.
  • Early surgical interventions like releasing incisions and delayed grafting are vital for limb salvage.
  • Conservative amputation with potential revision is recommended for necrotic extremities.

Bacterial Meningitis I: Introduction01:22

Bacterial 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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
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...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
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,...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
