Insights

A rare Campylobacter fetus subsp. fetus infection caused an internal iliac artery aneurysm in a patient. Successful treatment involved surgery and antibiotics, highlighting the need for accurate bacterial identification in infectious aneurysm cases.

Area of Science:

  • Infectious Diseases
  • Vascular Surgery
  • Microbiology

Background:

  • Infective aneurysms are rare but serious vascular infections.
  • Campylobacter fetus is an uncommon cause of infective aneurysms, particularly involving peripheral arteries.
  • Accurate identification of bacterial species is crucial for understanding epidemiology and pathogenicity.

Observation:

  • A 67-year-old male presented with persistent fever and was diagnosed with an internal iliac artery aneurysm.
  • Blood culture identified a gram-negative spiral rod.
  • Initial identification via MALDI-TOF MS suggested Campylobacter fetus subsp. venerealis, but genetic analysis confirmed Campylobacter fetus subsp. fetus.

Findings:

  • The patient's infective aneurysm was successfully treated with emergency aneurysm resection and 4 weeks of antibiotic therapy.
  • Peripheral artery involvement by Campylobacter fetus is uncommon.
  • Accurate species-level identification of Campylobacter fetus is critical for understanding its epidemiology and pathogenicity.

Implications:

  • This case underscores the importance of advanced diagnostic techniques, including genetic analysis, for precise bacterial identification.
  • Effective management of rare infective aneurysms requires a multidisciplinary approach.
  • Further research into Campylobacter fetus pathogenicity and host-pathogen interactions is warranted.

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

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...
