Summary
Propionibacterium acnes endocarditis, though rare, can manifest as lower limb fasciitis in patients with vascular prostheses. Prolonged blood cultures are crucial for diagnosing this challenging infection.
Area of Science:
- Cardiology
- Infectious Diseases
- Vascular Surgery
Background:
- Propionibacterium acnes endocarditis is a rare and diagnostically challenging condition.
- Infective endocarditis often involves prosthetic valves, but atypical presentations are increasingly recognized.
Observation:
- A 54-year-old patient with a history of aortic surgery developed recurrent lower limb myalgia and fasciitis.
- Imaging revealed fasciitis and increased 18-Fluorodeoxyglucose uptake in the aortic prosthesis and lower limb muscles.
- Blood cultures, after prolonged incubation, identified Propionibacterium acnes.
Findings:
- The patient was diagnosed with infective endocarditis caused by Propionibacterium acnes, revealed by lower limb emboli.
- Surgical removal of the infected aortic prosthesis led to a favorable outcome.
Implications:
- Propionibacterium acnes should be considered in patients with vascular prostheses presenting with unusual inflammatory conditions.
- Extended blood culture incubation periods are essential for identifying Propionibacterium acnes in suspected cases of prosthetic valve endocarditis.

Endocarditis II: Clinical Features of Infective Endocarditis
454
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 I: Introduction
415
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...

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 Management
342
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...

The de Broglie Wavelength

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

The Aufbau Principle and Hund's Rule
72.4K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...
