A 68-year-old woman presented with an acute onset of lower abdominal pain. A CT scan of the pelvis showed acute crystal deposition arthritis, and her symptoms markedly reduced with non-steroidal anti-inflammatory drugs. Further, a radiographic evaluation of the right knee joint and CT of the cervical spine revealed calcification; calcium pyrophosphate (CPP)(More)
Introduction. The diagnosis of infective endo-carditis is typically based on clinical presentation, positive blood cultures, and echocardiography findings. In particular, echocardiography is central to the diagnosis and management of patients with infective endocarditis. 1 If adequate echocardiographic findings cannot be observed secondary to artifacts, an(More)
OBJECTIVE While much attention is given to the fifth vital sign, the utility of the 4 classic vital signs (blood pressure, respiratory rate, body temperature, and heart rate) has been neglected. The aim of this study was to assess a possible association between vital signs and the Sequential Organ Failure Assessment (SOFA) score in patients with sepsis. (More)
Lemierre's syndrome is only very rarely caused by Porphyromonas asaccharolytica. Here, we report the case of a 35-year-old man who developed a left peritonsillar abscess, thrombophlebitis of the left internal jugular vein, and septic embolization of both lungs. Anaerobic P. asaccharolytica was isolated in the blood cultures, and we subsequently confirmed(More)
BACKGROUND The aim of this study was to evaluate the clinical usefulness of a semiquantitative procalcitonin kit for assessing severity of sepsis and early determination of mortality in affected patients. METHODS This was a prospective, observational study including 206 septic patients enrolled between June 2008 and August 2009. Disseminated intravascular(More)
A 56-year-old man presented to our department with a 2-month history of fever and chills. He had received a mitral valvuloplasty 3 years ago. He had been administered levofloxacin for 2 months. We discontinued levofloxacin and repeated the blood cultures. Bacterial blood cultures were positive and transoesophageal echocardiography revealed vegetation(More)
A 29-year-old woman was admitted to our hospital with fever and abdominal pain. Abdominal echogram and CT revealed intra-abdominal lymphadenopathy. Seven days after the onset, she developed cervical lymphadenitis. Kikuchi-Fujimoto's disease (KFD) was diagnosed on cervical lymph node biopsy. Although KFD with intra-abdominal lymphadenopathy is rare, it(More)

A few reported cases of infective endocarditis exist, with no reports describing involvement of blood access infection. CASE(More)
