Endocarditis I: Introduction01:25

Endocarditis I: Introduction

2
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...

Endocarditis III: Medical Management

2
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...

Endocarditis II: Clinical features and Diagnostic Tests

2
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

2
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

3
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Myocarditis I: Introduction01:21

Myocarditis I: Introduction

2
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Cardiology

Background:

  • Cosmetic colored contact lenses are increasingly popular, especially among younger individuals.
  • Improper use or poor hygiene associated with contact lenses can lead to ocular infections.
  • Ocular infections can potentially lead to systemic complications, though rarely endocarditis.

Purpose of the Study:

  • To report a rare case of infective endocarditis secondary to cosmetic contact lens use.
  • To highlight the potential systemic risks associated with non-prescribed or improperly used contact lenses.
  • To emphasize the importance of considering contact lens-related infections in patients presenting with unexplained endocarditis.

Main Methods:

  • A case study of a 17-year-old female presenting with fever, fatigue, and vision loss.
  • Diagnostic workup included echocardiography to assess cardiac involvement.
  • Treatment involved initial mitral valve plasty, followed by redo surgery with bioprosthetic valve replacement due to infection relapse.

Main Results:

  • Echocardiography revealed vegetation on the mitral valve, indicative of infective endocarditis.
  • No other systemic infectious source was identified, strongly suggesting contact lens use as the origin.
  • The patient required two surgical interventions to manage the persistent infection and valve damage.

Conclusions:

  • Cosmetic contact lens usage can be a rare but serious cause of infective endocarditis.
  • Traumatic injury from contact lenses may facilitate hematogenous spread of infection to heart valves.
  • This case underscores the critical need for proper contact lens hygiene and awareness of potential systemic complications.
