Insights

Disseminated anaerobic bacterial infections are rare. This case highlights Parvimonas micra and Prevotella oralis causing septic emboli, likely originating from periodontal disease.

Area of Science:

  • Oral microbiology
  • Infectious diseases

Background:

  • Parvimonas micra and Prevotella oralis are common oral commensals.
  • Anaerobic bacterial infections necessitate prompt diagnosis and treatment.

Observation:

  • A patient presented with multifocal infiltrates indicative of septic embolism.
  • The patient exhibited polymicrobial bacteremia involving Parvimonas micra and Prevotella oralis.

Findings:

  • Periodontal disease was identified as the probable source of the disseminated infection.
  • Septic emboli were observed in the lungs, liver, and spleen.

Implications:

  • This case underscores the importance of considering oral bacteria in severe systemic infections.
  • Early recognition of periodontal disease as a potential nidus for anaerobic bacteremia is crucial.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Endocarditis II: Clinical Features of Infective Endocarditis

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...

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

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...
