Purulent pericarditis caused by group a streptococcus. (1/9)

Purulent pericarditis is a rare disease that is most often caused by organisms such as Staphylococcus aureus, Streptococcus pneumoniae, viridans streptococci, Haemophilus influenzae, and anaerobic bacteria. We present an unusual case of purulent pericarditis caused by Streptococcus pyogenes, Lancefield group A streptococcus (GAS), and we provide a review of the literature.  (+info)

Pericardial tamponade masquerading as septic shock. (2/9)

A 53-year-old man with steroid dependent rheumatoid arthritis presented with fever and serous articular drainage. Oral antibiotics were initially prescribed. Subsequent hemodynamic instability was attributed to septic shock. Further evaluation revealed a pericardial effusion with tamponade. Pericardiocentesis of purulent fluid promptly corrected the hypotension. Proteus mirabilis was later isolated from both the infected joint and the pericardial fluid. This is the first report of combined Proteus mirabilis septic arthritis and purulent pericarditis. It documents the potential for atypical transmission of Gram-negative pathogens, to the pericardium, in patients with a high likelihood of preexisting pericardial disease. In immunocompromised patients, the typical signs and symptoms of pericarditis may be absent, and the clinical presentation of pericardial tamponade may be misinterpreted as one of septic shock. This case underscores the value of a careful physical examination and proper interpretation of ancillary studies. It further illustrates the importance of initial antibiotic selection and the need for definitive treatment of septic arthritis in immunocompromised patients.  (+info)

Bacterial pericarditis and tamponade due to nonencapsulated Haemophilus influenzae complicating a case of adult community-acquired pneumonia. (3/9)

We report a case of bacterial pericarditis in an immunologically competent adult female caused by nonencapsulated Haemophilus influenzae (H influenzae) that was complicated by the acute development of life-threatening pericardial tamponade. H influenzae is a gram-negative coccobacillus, a pathogen most frequently associated with childhood exanthema (otitis media, meningitis) and, less frequently, adult pneumonia. Encapsulated, type b, or typable H influenzae is the strain implicated in childhood infections. On the other hand, nonencapsulated or nontypable H influenzae is the specific strain most often associated with exacerbation of chronic obstructive airway disease. Bacterial pericarditis caused by either subtype of H influenzae is exceedingly rare. We have located only 15 previously reported cases of H influenzae pericarditis occurring in adults in the world medical literature, the majority of which date back to the pre-antibiotic era. In 12 of these 15 cases (the only cases in which typing could be accomplished), the encapsulated strain of H influenzae was cultured from the pericardial fluid. Thus, to the best of our knowledge, we are reporting here the first case of bacterial pericarditis caused by nonencapsulated H influenzae in an immunologically competent adult.  (+info)

Complications after transcatheter closure of patent ductus arteriosus. (4/9)

To evaluate the short- and mid-term results and complications ensuing the transcatheter closure of patent ductus arteriosus (PDA). Between October 1999 and December 2005, 117 patients (34 males and 83 females) underwent attempted percutaneous closure of PDA with a minimum diameter of more than 3 mm. Follow-up evaluations were conducted at 1 day and 1, 3, 6, 12 months after the performance of the transcatheter closure. The median age of patients at catheterization was 11 yr (range, 0.6 to 68 yr), median weight was 30 kg (range, 6 to 74 kg), and the median diameter of PDA was 4 mm (range, 3 to 8 mm). This procedure was conducted successfully in 114 patients (97.4%), using different devices. Major complications were detected in 4 patients (3.4%); significant hemolysis (2), infective endocarditis (1), failed procedure due to embolization (1). Minor complications occurred in 6 patients (5.1%); mild narrowing of the descending aorta (2) and mild encroachment on the origin of the left pulmonary artery (4). Although the transcatheter closure of PDA may be considered to be effective, several complications, including hemolysis, embolization, infective endocarditis, and the narrowing of adjacent vessels may occur in certain cases.  (+info)
