Lemierre-like syndrome caused by community-associated methicillin-resistant Staphylococcus aureus complicated by hemorrhagic pericarditis.

OBJECTIVE: To describe an infant with Lemierre-like syndrome caused by community-associated methicillin-resistant Staphylococcus aureus whose course was complicated by hemorrhagic pericarditis. DESIGN: Case report. SETTING: A 30-bed, pediatric intensive care unit at a tertiary care children's hospital. PATIENT: A 7-month-old infant presented with fever and torticollis attributable to a retropharyngeal abscess and left internal jugular venous thrombosis. He was treated with antibiotics and anticoagulation, and his course was complicated by hemorrhagic pericarditis and cardiac tamponade. INTERVENTIONS: Resuscitation of shock; video-assisted thoracoscopic drainage of bilateral empyema with pleural decortication; vancomycin and clindamycin treatment of methicillin-resistant Staphylococcus aureus; incision and drainage of retropharyngeal abscess; treatment of internal jugular venous thrombus with anticoagulation; and treatment of pericardial tamponade by insertion of pericardial drain. MEASUREMENTS AND MAIN RESULTS: Methicillin-resistant Staphylococcus aureus from blood and pleural fluid peel cultures were multi-locus sequence type 8, Panton-Valentine leukocidin-positive, and contained SCCmec IV, findings consistent with USA300 pulsotype. There was complete recovery from this life-threatening infection. CONCLUSIONS: Septic jugular venous thrombophlebitis complicating upper airway infections is a rare but serious acute medical condition. We present an infant with methicillin-resistant Staphylococcus aureus infection and clinical features that overlapped those described by Lemierre, in whom hemorrhagic pericarditis developed while receiving anticoagulation therapy. Anticoagulation, if used, should be closely monitored in this population.

Mollaret's meningitis due to human herpesvirus 6 in an adolescent.

We report the first pediatric case of Mollaret meningitis in an adolescent female with acute lymphoblastic leukemia in remission. This patient had signs and symptoms consistent with meningitis, with three episodes over a 3-month period. Human herpesvirus 6 (HHV-6) was identified during her last episode from polymerase chain reaction assay of a cerebrospinal fluid specimen. She was treated successfully with foscarnet, after which HHV-6 was undetectable in her cerebrospinal fluid.
