Moraxella catarrhalis was isolated from blood from a 41-year-old man who had a 24-hour history of increasing pain in and swelling of the left knee. No history of trauma, arthropathy, fever, chills, cough, or chest pain was noted. What is believed to be the first case of bacteremia caused by M. catarrhalis that was associated with septic arthritis is described in this report. The case presented suggests the pathophysiology of this rare condition. One previous case of septic arthritis caused by M. catarrhalis without documented bacteremia has been reported.

Two young men presented with prolonged hectic fever and chills followed by chest pain, dyspnea and hemoptysis. The chest films revealed multiple lung infiltrates, and blood cultures yielded Staphylococcus aureus. Echocardiographic examination confirmed the diagnosis of tricuspid valve endocarditis. Multiple punctate lesions in the bilateral inguinal areas and dragon tattoos over the forechest gave rise to the suspicion of drug abuse. After prolonged antimicrobial therapy, bacteremia was eliminated, and elective vegetectomy and valvuloplasty were performed on one of the patients. The other one suffered recurrent episodes of pulmonary embolism. Disappearance of the large vegetation was disclosed by echocardiography. Both of them eventually regained their health with the abstinence of drugs. This report illustrates two typical cases of infective endocarditis in drug addicts.

Human immunodeficiency virus (HIV) infection is associated with abnormalities of humoral immunity that result in an increased incidence of bacterial pneumonia. From 2% to 10% of acquired immunodeficiency syndrome (AIDS)-associated pneumonia is caused by encapsulated bacteria. Clinical features are usually typical of community-acquired pneumonia and include fever, productive cough, and chest pain. Focal radiographic infiltrates, an elevated WBC count, and mild hypoxemia are commonly observed. Streptococcus pneumoniae, Haemophilis influenzae, other Streptococcus species, and Branhamella catarrhalis are the predominant organisms. Bacteremia is frequent, especially with S pneumoniae infections. Despite a rapid response to antibmicrobial agents, many patients experience recurrences. Prevention of bacterial infections with prophylactic antibiotics and immunizations is recommended for selected HIV-infected patients.

The efficacy and safety of oral ciprofloxacin (750 mg every 12 hours) in the treatment of infections was evaluated in 84 geriatric patients. Duration of treatment ranged from three to 42 days (for a mean of 10.45 days). Satisfactory responses (cured or improved) were noted in 33 of 34 cases of urinary tract infections (97%); in 11 of 13 cases of lower respiratory tract infections (85%); in four of nine cases of skin and skin structure infections (44%); and in both cases of bone infection and bacteremia. Bacteriological cure rates were 91% of 33 urinary tract infections; 83% of 12 lower respiratory tract infections; 62% of eight skin and skin structure infections; and in both cases of bone infection and bacteremia. Three patients evaluable for clinical purposes were bacteriologically unevaluable. Overall clinical efficacy and bacteriological cure rates were 86% and 85%, respectively. Of the 78 evaluable pathogens isolated, 70 (90%) were eradicated. Adverse reactions occurred in 24 patients (29%) and included candida colonization in eight, gastrointestinal upset in six, dermatologic symptoms in five, and vaginal candidiasis, chest pain, renal failure, tremors, monocytosis, thrombocytosis, and increased serum theophylline level in one patient each. Ciprofloxacin appears to be a safe and effective treatment for infections in geriatric patients. Advantages of the oral form include cost effectiveness and decreased length of hospitalization.

We describe a geriatric patient with acute substernal chest pain thought to be due to coronary heart disease, who was subsequently found to have Staphylococcus aureus bacteremia associated with infection of the thymus and manubriosternal joint. To our knowledge, this is the first report of (1) a thymic abscess in a geriatric patient, (2) a thymic abscess associated with bacteremia, (3) extra-articular extension of manubriosternal pyarthrosis, and (4) manubriosternal pyarthrosis in the geriatric age group.

We report on a 58-year-old male diagnosed as having primary myelofibrosis with thrombocytopenia, who died of fatal septic shock and rhabdomyolysis after platelet concentrates (PCs) transfusion. The initial diagnosis of primary myelofibrosis was established by splenomegaly, leukoerythroblastosis and bone marrow fibrosis. PCs were transfused because of thrombocytopenia with marked bleeding tendency. Soon after the PCs transfusion in March 2000, he had attacks of chest pain, back pain and myalgia, then went into shock and died of unknown causes. PCs were suspected as being the cause of death, because Streptococcus pneumoniae was found in the culture of PCs in the WBC-reduction in-line filter and fresh frozen plasma from the same donor preserved in the Japan Red Cross Center. Rhabdomyolysis, neutrophil infiltration and phagocytosed bacteria were found from the autopsy materials, which were identified by DNA analysis as the same species found in the PCs. PCs are kept at room temperature because platelet function is lost in the cold. When PCs are contaminated with bacteria, marked multiplication induces fatal bacteremia. This is a rare report in Japan of fatal septic shock caused by PCs with bacterial contamination. We must pay strict attention to bacterial contamination in blood components.

Cardiovascular infections due to Salmonella enterica are infrequently reported, so their clinical features, prognosis, and optimal treatment are not completely known. Mortality associated with aortitis and endocarditis caused by nontyphoidal Salmonella remains exceedingly high. In this review of cases of cardiovascular infections due to Salmonella enterica studied in 2 hospitals in Madrid, we tried to assess the clinical manifestations and the procedures leading to diagnosis in addition to treatment and outcome. To complete the spectrum of infections related to cardiovascular surgery, cases of postoperative mediastinitis, pericarditis, and infections associated with cardiac devices were also included.Twenty-three patients were reviewed: 11 had mycotic aneurysms; 7 had endocarditis; 2 had device-related infections; and 3 had pericarditis, mediastinitis, and infection of an arteriovenous fistula, respectively. The risk of endovascular infection in patients older than 60 years with bacteremia due to nontyphoidal Salmonella was 23%. Most patients with aortitis had risk factors for atherosclerosis, and 6 had preexisting atherosclerotic aortic aneurysms. All except 1 patient with endocarditis had underlying cardiac disorders. Acquired immunodeficiency disease (AIDS) was a major risk factor for salmonella bacteremia in 1 patient with aortitis and 1 with endocarditis. Fever, unremitting sepsis, "breakthrough" and relapsing bacteremia were the most common clinical findings. In addition, abdominal or thoracic pain and cardiac failure and pericarditis were common features in patients with aortitis and endocarditis respectively. Computed tomography (CT) scan, arteriography, and echocardiography were the main diagnostic tools. Mortality associated with mycotic aneurysms and endocarditis due to S. enterica was 45% and 28%, respectively. Thoracic aneurysms, rupture, and shock at the time of diagnosis were associated with increased mortality in patients with aortitis. In situ bypass grafting was successfully performed in most cases. After surgery, antimicrobial therapy was continued for 4-9 weeks. No relapses were observed after a mean follow-up of 64 months. Antimicrobial therapy alone or combined with valve replacement or excision of a ventricular aneurysm was successful treatment for most patients with salmonella endocarditis. Combined medical and surgical treatment was required for patients with mediastinitis and pericarditis, and patients with device-related infections needed removal of the complete device. Diagnosis of aortitis due to nontyphoidal Salmonella should be established as early as possible to reduce mortality. Patients older than 60 years who have positive blood cultures for Salmonella along with fever and back, abdominal, or chest pain should have an extensive workup for infective aortitis. Immediate bactericidal antimicrobial therapy should be started and a CT scan should be performed on an emergency basis. If a mycotic aneurysm is found, surgical resection should follow as soon as possible. Resection of the aneurysm with in situ bypass grafting is the procedure of choice. Postoperative antimicrobial therapy for 6-8 weeks seems enough to avoid relapses. Optimal treatment of patients with endocarditis occurring on ventricular aneurysms must include resection of the aneurysmal sac. Salmonella endocarditis can be successfully treated with antimicrobials alone. Valve replacement should be reserved for patients with cardiac failure or persisting sepsis, and for those who relapse after discontinuation of antimicrobial therapy.

We review 170 previously reported cases of sternoclavicular septic arthritis, and report 10 new cases. The mean age of patients was 45 years; 73% were male. Patients presented with chest pain (78%) and shoulder pain (24%) after a median duration of symptoms of 14 days. Only 65% were febrile. Bacteremia was present in 62%. Common risk factors included intravenous drug use (21%), distant site of infection (15%), diabetes mellitus (13%), trauma (12%), and infected central venous line (9%). No risk factor was found in 23%. Serious complications such as osteomyelitis (55%), chest wall abscess or phlegmon (25%), and mediastinitis (13%) were common. Staphylococcus aureus was responsible for 49% of cases, and is now the major cause of sternoclavicular septic arthritis in intravenous drug users. Pseudomonas aeruginosa infection in injection drug users declined dramatically with the end of an epidemic of pentazocine abuse in the 1980s. Sternoclavicular septic arthritis accounts for 1% of septic arthritis in the general population, but 17% in intravenous drug users, for unclear reasons. Bacteria may enter the sternoclavicular joint from the adjacent valves of the subclavian vein after injection of contaminated drugs into the upper extremity, or the joint may become infected after attempted drug injection between the heads of the sternocleidomastoid muscle. Computed tomography or magnetic resonance imaging should be obtained routinely to assess for the presence of chest wall phlegmon, retrosternal abscess, or mediastinitis. If present, en-bloc resection of the sternoclavicular joint is indicated, possibly with ipsilateral pectoralis major muscle flap. Empiric antibiotic therapy may need to cover methicillin-resistant Staphylococcus aureus (MRSA).

We performed an observational analysis of a prospective cohort of immunocompetent hospitalized adults with community-acquired pneumonia (CAP) to determine the epidemiology, clinical features, and outcomes of pneumonia in patients with diabetes mellitus (DM). We also analyzed the risk factors for mortality and the impact of statins and other cardiovascular drugs on outcomes. Of 2407 CAP episodes, 516 (21.4%) occurred in patients with DM; 483 (97%) had type 2 diabetes, 197 (40%) were on insulin treatment, and 119 (23.9%) had end-organ damage related to DM. Patients with DM had different clinical features compared to the other patients. They were less likely to have acute onset, cough, purulent sputum, and pleural chest pain. No differences in etiology were found between study groups. Patients with DM had more inhospital acute metabolic complications, although the case-fatality rate was similar between the groups. Independent risk factors for mortality in patients with DM were advanced age, bacteremia, septic shock, and gram-negative pneumonia. Patients with end-organ damage related to DM had more inhospital cardiac events and a higher early case-fatality rate than did the overall population. The use of statins and other cardiovascular drugs was not associated with better CAP outcomes in patients with DM. In conclusion, CAP in patients with DM presents different clinical features compared to the features of patients without DM.

We present the first reported case of systemic infection with Neisseria meningitidis serogroup W-135 sequence type (ST)-11 in Japan. A 44-year-old woman presented with high fever, sore throat, and fatigue and was diagnosed with N. meningitidis bacteremia. The causative strain was identified as serogroup W-135 ST-11 by polymerase chain reaction and multilocus sequence typing. Approximately 1 month after treatment, she developed high fever, dyspnea, chest pain, and shoulder pain due to pericarditis, polyarthritis, and tenosynovitis, which are all relatively common immunoreactive complications of W-135 ST-11 meningococcal infections. This causative strain was the same as that responsible for an outbreak of meningitis among Hajj pilgrims in 2000. The strain is now found worldwide because it can attain a high carriage rate and has a long duration of carriage. We suspect that our patient's infection was acquired from an imported chronic carrier.
