Infection due to organisms of the Mycobacterium fortuitum complex after augmentation mammaplasty: clinical and

Insights

Periprosthetic infections from Mycobacterium fortuitum and Mycobacterium chelonei are challenging after breast augmentation. These chronic, refractory wound infections often require delayed diagnosis and complicate further procedures.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Plastic Surgery

Background:

  • Periprosthetic infections pose a significant challenge in reconstructive surgery.
  • Mycobacterium fortuitum and Mycobacterium chelonei are rapidly growing mycobacteria known to cause opportunistic infections.

Purpose of the Study:

  • To describe the clinical characteristics and outcomes of periprosthetic infections caused by Mycobacterium fortuitum and Mycobacterium chelonei following breast augmentation.
  • To analyze the diagnostic challenges and treatment responses in these specific mycobacterial infections.

Main Methods:

  • Retrospective case series analysis of 17 women with periprosthetic infections.
  • Review of clinical data, microbiological findings, and treatment regimens.
  • Antimicrobial susceptibility testing of Mycobacterium isolates.

Main Results:

  • Seventeen cases of periprosthetic infection after breast augmentation were identified over 3.5 years.
  • Median incubation period was 28 days; diagnosis was often delayed.
  • Infections presented as chronic, refractory wounds with serosanguineous or purulent discharge.
  • Mycobacterium fortuitum isolates showed susceptibility to amikacin, but strain variability was noted.
  • Recurrent infections complicated revision surgeries.

Conclusions:

  • Periprosthetic infections with rapidly growing mycobacteria are a serious complication of breast augmentation.
  • Early diagnosis and appropriate antimicrobial therapy are crucial but challenging.
  • These infections can lead to persistent morbidity and affect reconstructive outcomes.

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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...

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
