Left ventricular pseudoaneurysm is an uncommon complication of infective endocarditis, usually presenting within several weeks of the infective episode. We describe a 37-year-old man who presented with exertional dyspnea nearly a year after a prolonged hospitalization for lung abscess. Imaging studies showed new aortic valve regurgitation and a giant pseudoaneurysm extending inferoposteriorly from the left ventricle. At thoracotomy, a perforated aortic valve was found, suggesting a healed endocarditis. The patient underwent successful aneurysmectomy and patch closure with aortic valve repair. This case underscores the potential for very late nonvalvular cardiac complications of infective endocarditis and is also distinctive because of the large size of the pseudoaneurysm.

Gemella morbillorum is a facultatively anaerobic Gram-positive coccus which forms part of the normal flora of the oro-pharynx and the upper respiratory tract. It rarely causes human infection but has been described previously in cases of empyema and lung abscess, septic shock, endocarditis, meningitis, and osteomyelitis. We describe a case of septic arthritis due to G. morbillorum occurring in an otherwise healthy 42-year old man and review previous reports of infection in the literature.

A 5-month-old boy who had previously undergone a modified Norwood procedure for hypoplastic left heart syndrome presented for elective cardiac catheterization before undergoing the next stage of repair. The catheterization demonstrated mild stenosis of the right ventricle-to-pulmonary artery Sano conduit. The patient became hypoxic and febrile at the end of the procedure and died in the intensive care unit the next day. Postmortem examination demonstrated a vegetation containing Gram-positive cocci in the conduit and a right upper lobe lung abscess also containing Gram-positive cocci. The authors report the first case of Sano shunt endocarditis further complicated by septic pulmonary embolus and review similar infections in this population. Shunt infection may be an underrecognized cause of interstage mortality among patients undergoing a modified Norwood procedure.

Pasteurella multocida infections in humans can present as localized infections of soft tissues surrounding the lesions, as respiratory tract infections or as systemic infections with slow or fulminant development. Over 90% of human infections are cases of wound infections or abscesses related to a bite, scratch, or licking of skin lesions by a cat or dog. Severe systemic diseases such as pneumonia, lung abscess, peritonitis, endocarditis, meningitis and sepsis are also well known, especially in patients with underlying medical conditions. In this paper we report on an immunocompromised patient who was bitten by an unknown cat and very quickly developed fulminant sepsis, dying 70 hours after the cat bite, despite all the intensive care, therapy and reanimation he was given. Unfortunately, he asked for medical help too late. We emphasize the need for primary healthcare to provide more information to patients at risk of infections from contact with animals and to warn them about the possible consequences of injuries, even when the animals are pets.

Capnocytophaga is an opportunistic gram-negative anaerobic bacillus found in the oropharyngeal cavity of mammals and is associated with periodontal disease in humans. Sepsis, osteomyelitis, lung abscess, endocarditis, and meningitis have been reported in humans following animal bites. Perinatal infection with Capnocytophaga is infrequent and is generally considered to have a low risk of morbidity to the mother and fetus. We report a case of neonatal Capnocytophaga sepsis associated with the development of severe cystic periventricular leukomalacia.

We report the case of a lung abscess due to Prevotella baroniae with a co-infection by Abiotrophia defective, which is a 'nutritionally variant streptococci' (NVS), in a 48-year-old patient. The delayed diagnosis of this co-infection led to multiple failures of medical treatment and need for surgery. Pathogenicity of these bacteria is well known, particularly in endocarditis, but not in lung infection. In pulmonary abscesses, co-infection with NVS is difficult to detect. It may explain some medical treatment failures. This case highlights the importance to systematically search for and consider NVS in such clinical contexts.
