Infective endocarditis caused by methicillin-resistant Staphylococcus aureus in a young woman after ear piercing: a case report

Metastatic Infection Following Ear Piercing Detected by FDG PET/CT

ABSTRACT

Ear piercing is currently a common practice. Although rare, ear piercing can cause systemic infections. We present a case of an 18-year-old woman who underwent FDG PET/CT for prolonged fever and bacteremia. FDG PET/CT showed multifocal FDG uptake at the site of piercing in the left ear, and in the spleen and left atrium and deep thigh vessel. The patient was diagnosed with an ear piercing infection with multiple metastatic infections.

Antibiotic Prophylaxis for Infective Endocarditis: A Survey of Practice Among Pediatric Cardiology Providers

The 2007 American Heart Association (AHA) guidelines limited antibiotic prophylaxis (AP) for infective endocarditis (IE) to fewer patients with predisposing cardiac conditions (PCC). We surveyed the American Academy of Pediatrics Section on Cardiology and Cardiac Surgery (AAP SOCCS) on their recommendations for AP for a number of PCC and procedures. We report on those 173 respondents who follow the 2007 AHA guidelines. AP rates for high-risk PCCs clearly meeting AHA criteria ranged from 70.5-89.8%. Conversely, for PCCs which did not meet AHA criteria, prescribing rates varied from <1% to 29.5%. PCC for which AP indication was unclear per guidelines, AP rates similarly varied from 9.9-39.8%. Similar variability is noted in AP for various procedures in setting of high-risk PCC. There is variability in AP prescribing practices among pediatric cardiologists based on both underlying PCC and noncardiac procedures in the setting of underlying cardiac disease.

Post-mortem findings in Staphylococcus aureus acute infective endocarditis

Infective endocarditis (IE) is a microbial infection of the heart valves or the mural endocardium that leads to the formation of vegetations composed of thrombotic debris and microorganisms often associated with the destruction of the cardiac tissues. Most of the infections are bacterial (bacterial endocarditis), although fungi and other microorganisms can be etiological agents. Causative organisms differ among the major high-risk groups. Virulent microorganisms like Staphylococcus aureus, commonly found on the skin, can infect normal or deformed valves and are responsible for 20-30% of all IE cases. Staphylococcus aureus is the major offender in IE among intravenous drug abusers. Acute infective endocarditis is typically caused by infection of a previously normal heart valve by a highly virulent organism (e.g., Staphylococcus aureus) that rapidly produces necrotizing and destructive lesions. These infections may be difficult to cure with antibiotics, and despite appropriate treatment, death can ensue within days to weeks. Here we present autopsy findings of a 31-year-old male patient who died of acute infective endocarditis caused by Staphylococcus aureus as the causative organism.

Daith Piercing: Wonder Treatment or Untested Fad?

Daith piercing is a form of body piercing that involves the crux of the ear's helix. While daith piercing has been used as an esthetic piercing since the 1990s, it is gaining popularity in the general population as an alternative treatment in chronic headaches, especially migraines. Despite its use, the evidence is currently lacking. Postulated hypotheses include vagal neuromodulation vs. placebo effect. We present a case of a 47-year-old female patient suffering from refractory cluster headache who underwent daith piercing. We aim to raise awareness among the general practitioners of this health-related practice prevalent in the community.

Bacterial chondritis complications following ear piercing

BACKGROUND

Body piercing has become widespread and is associated with increased complications. Post-piercing chondritis may lead to severe residual deformity. We aimed to report case patients presenting with post-piercing chondritis in our department and to describe clinical features and treatment.

PATIENTS AND METHODS

We conducted a retrospective study of patients presenting with post-piercing chondritis in the infectious disease department of Tenon Hospital, Paris, France.

RESULTS

We included 21 patients. Fifteen bacteriological cultures were positive (7 Pseudomonas aeruginosa, 5 Staphylococcus aureus, and three other). Dual intravenous antibiotic therapy was administered to 13 patients for a median duration of six days [2-8], replaced by an oral antibiotic therapy for a median duration of 15 days [7-40]. Eight patients received oral antibiotic monotherapy for 10 days [7-30]. Median duration of antibiotic therapy was 16 days. Earring removal was performed for 18 patients. No ear deformity or general complication was reported.

CONCLUSION

Transcartilaginous ear piercing may lead to infectious complications or deformity. In case of chondritis, early administration of an antibiotic therapy active against P. aeruginosa and S. aureus is recommended. Specific guidelines are needed.

Infective endocarditis in previously healthy children with structurally normal hearts

Structural heart disease, intravascular catheters, and invasive procedures are predisposing factors for infective endocarditis (IE). Data on IE in children with structurally normal hearts and no predisposing factors are limited. We aim to characterize IE (definite or possible by Duke criteria) in such a subgroup of pediatric patients (age <18 years) who were treated at our medical center. Of 51 events of IE in 50 children, 9 (18 %) had no predisposing factors. These infections were all community-acquired and presented with fever, a newly detected heart murmur, diagnostic echocardiographic findings, and left-sided infection. Clinical course was characterized by acute onset (n = 8 of 9) with a 100 % complication rate (heart failure or embolic phenomena). Emergency cardiac surgery was performed in 7 children (Ross surgery [n = 4], mitral valve replacement [MVR; n = 2], and valve repair [n = 1]). Causative organisms were S. aureus (n = 3), S. pneumoniae (n = 2), H. parainfluenzae (n = 1), and K. kingae (n = 1). In contrast, IE in children with predisposing factors (42 of 51 [82 %]) was frequently health care-associated (30 of 42), right-sided (20 of 42, p = 0.041), and with lower rates of diagnostic echocardiographic findings (28 of 42, p = 0.041), complications (16 of 42, p < 0.001), and surgical intervention (9 of 42, p = 0.002). Causative organisms were mainly viridans streptococci (n = 9), Candida species (n = 8), coagulase-negative staphylococci (n = 6), enteric Gram-negative bacilli (n = 6), S. aureus (n = 5), and K. kingae (n = 3). Mortality was 11 % in both groups. We conclude that pediatric IE in children with and without predisposing factors differs significantly. Due to the acute and complicated course of the latter, high awareness among pediatricians and prompt diagnosis are crucial.
