Endocarditis I: Introduction01:25

Endocarditis I: Introduction

177
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 II: Clinical Features of Infective Endocarditis

149
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 III: Medical Management

96
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 IV: Nursing Management01:29

Endocarditis IV: Nursing Management

148
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

191
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

163
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:

  • Medical Microbiology
  • Infectious Diseases

Background:

  • Gordonia species are recognized as opportunistic human pathogens.
  • These bacteria can cause secondary infections in susceptible individuals.

Purpose of the Study:

  • To report the second documented case of endocarditis caused by Gordonia bronchialis.
  • To review all reported cases of endocarditis attributed to Gordonia species.

Main Methods:

  • Identification of the causative agent was confirmed using matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing.
  • Antimicrobial susceptibility testing was performed using MIC test strips.

Main Results:

  • An 88-year-old female patient presented with pacemaker-induced endocarditis due to Gordonia bronchialis.
  • The patient received a 6-week course of ceftriaxone and ciprofloxacin post-pacemaker explant, showing a favorable clinical outcome.

Conclusions:

  • This case reinforces the pathogenic potential of Gordonia bronchialis.
  • It underscores the significant risk posed by environmental bacteria in causing human infections, particularly in vulnerable patients.
