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

<p>Abstract</p> <p>Introduction</p> <p>Ear piercing is a common practice among Korean adolescents and young women and usually is performed by nonmedical personnel, sometimes under suboptimal hygienic conditions. Consequently, ear piercing has been associated with various infectious complications, including fatal infective endocarditis. We report a case of infective endocarditis that was caused by community-associated methicillin-resistant <it>Staphylococcus aureus </it>after ear piercing and that was accompanied by a noticeable facial rash.</p> <p>Case presentation</p> <p>A 29-year-old Korean woman underwent ear piercing six days before hospitalization. On admission, she had fever, erythematous maculopapular rashes on her face, signs of generalized emboli, vegetation in her mitral valve, and methicillin-resistant <it>S. aureus </it>bacteremia. On the basis of the blood culture results, she was treated with vancomycin in combination with gentamicin. On day six of hospitalization, a rupture of the papillary muscle of her mitral valve developed, and emergency cardiac surgery replacing her mitral valve with a prosthetic valve was performed. After eight weeks of antibiotic therapy, she was treated successfully and discharged without significant sequelae.</p> <p>Conclusions</p> <p>Numerable cases of body piercing-related infective endocarditis have been reported, and since ear piercing is commonplace nowadays, the importance of risk recognition cannot be overemphasized. In our report, a patient developed infective endocarditis that was caused by methicillin-resistant <it>S. aureus </it>after ear piercing and that was accompanied by an interesting feature, namely facial rash.</p

Metabolic syndrome in young children: definitions and results of the IDEFICS study

OBJECTIVE: To estimate the prevalence of the metabolic syndrome (MetS) using reference standards obtained in European children and to develop a quantitative MetS score and describe its distribution in children. DESIGN AND METHODS: Population-based survey in eight European countries, including 18745 children 2.0 to 10.9 years, recruited during a second survey. Anthropometry (weight, height and waist circumference), blood pressure and serum-fasting triglycerides, HDL cholesterol, glucose and insulin were measured. We applied three widely accepted definitions of the pediatric MetS and we suggest a new definition, to guide pediatricians in decisions about close monitoring or even intervention (values of at least three of the MetS components exceeding the 90th or 95th percentile, respectively). We used a z-score standardisation to calculate a continuous score combining the MetS components. RESULTS: Among the various definitions of MetS, the highest prevalence (5.5%) was obtained with our new definition requiring close observation (monitoring level). Our more conservative definition, requiring pediatric intervention gives a prevalence of 1.8%. In general, prevalences were higher in girls than in boys. The prevalence of metabolic syndrome is highest among obese children. All definitions classify a small percentage of thin or normal weight children as being affected. The metabolic syndrome score shows a positive trend with age, particularly regarding the upper percentiles of the score. CONCLUSIONS: According to different definitions of pediatric MetS, a non-negligible proportion of mostly prepubertal children are classified as affected. We propose a new definition of MetS that should improve clinical guidance. The continuous score developed may also serve as a useful tool in pediatric obesity research. It has to be noted, however, that the proposed cutoffs are based on a statistical definition that does not yet allow to quantify the risk of subsequent disease
