RESUMEN

From October 4 to November 2, 2001, the first 10 confirmed cases of inhalational anthrax caused by intentional release of Bacillus anthracis were identified in the United States. Epidemiologic investigation indicated that the outbreak, in the District of Columbia, Florida, New Jersey, and New York, resulted from intentional delivery of B. anthracis spores through mailed letters or packages. We describe the clinical presentation and course of these cases of bioterrorism-related inhalational anthrax. The median age of patients was 56 years (range 43 to 73 years), 70% were male, and except for one, all were known or believed to have processed, handled, or received letters containing B. anthracis spores. The median incubation period from the time of exposure to onset of symptoms, when known (n=6), was 4 days (range 4 to 6 days). Symptoms at initial presentation included fever or chills (n=10), sweats (n=7), fatigue or malaise (n=10), minimal or nonproductive cough (n=9), dyspnea (n=8), and nausea or vomiting (n=9). The median white blood cell count was 9.8 X 10(3)/mm(3) (range 7.5 to 13.3), often with increased neutrophils and band forms. Nine patients had elevated serum transaminase levels, and six were hypoxic. All 10 patients had abnormal chest X-rays; abnormalities included infiltrates (n=7), pleural effusion (n=8), and mediastinal widening (seven patients). Computed tomography of the chest was performed on eight patients, and mediastinal lymphadenopathy was present in seven. With multidrug antibiotic regimens and supportive care, survival of patients (60%) was markedly higher (<15%) than previously reported.

RESUMEN

Two patients with surgically implanted right atrial silastic catheters for home hyperalimentation developed central vein septic thrombophlebitis. Initial treatment including removal of the catheter and antibiotic therapy was unsuccessful and both patients had persistent fever and bacteremia. A clinical and microbiologic response occurred when anticoagulation therapy with heparin was added to the treatment regimen. Although a surgical approach has been emphasized in patients with peripheral vein suppurative thrombophlebitis, anticoagulation therapy may be a useful alternative in the treatment of patients with central vein infection.

RESUMEN

Bacteremia with Peptococcaceae is an uncommon clinical manifestation of infection with this family of microorganisms. A 20-month review of 12 patients with bacteremic infections due to anaerobic gram-positive cocci revealed that obstetrical patients during the peripartum period constitute the group at greatest risk for the development of such infections. Eight of the 12 patients were young women hospitalized on the obstetrical service. Seven patients had postpartum endometritis and one patient had chorioamnionitis. The remaining four patients include a single patient each with pylephlebitis and microabscesses of the liver, ascending cholangitis, thoracic empyema, and necrotizing soft-tissue infection. Bacteriologic identification of the microorganisms revealed the following: Peptostreptococcus micros (5 patients), Peptostreptococcus asaccharolyticus (5 patients), Peptostreptococcus magnus (1 patient), and Peptococcus species (1 patient). Eleven of the 12 patients received appropriate antibiotic therapy. All patients did well and there were no major sequelae.

RESUMEN

We have described a patient who had Candida albicans suppurative thrombophlebitis at the site of an indwelling intravenous catheter. The microbial etiology was established by needle aspiration of the venipuncture site, affording rapid and accurate identification of the infecting organism and providing prompt institution of therapy. Phlebectomy and a brief course of amphotericin B prevented further dissemination of the infection.
