Candida endocarditis associated with cardiac rhythm management devices: review with current treatment guidelines.

Coincident with an increased use of cardiac rhythm management devices (CRMD) has been an increase in the number of pacemaker and cardioverter-defibrillator infections. CRMD endocarditis accounts for about 10% of all device-related infections, and cardiac infection caused by Candida sp. is a rare event.

Comparative activity of telavancin and other antimicrobial agents against methicillin-resistant Staphylococcus aureus isolates collected from 1991 to 2006.

Background: Increasingly frequent reports of vancomycin treatment failures for serious methicillin-resistant Staphylococcus aureus (MRSA) infections provide impetus for comparative in vitro studies to assess the activity of newer antimicrobial agents against a range of MRSA isolates.

Methods: A sample of 168 MRSA derived from a long-term MRSA collection was subjected to susceptibility testing to telavancin, daptomycin, linezolid, tigecycline and vancomycin by broth micro-dilution. Data were reviewed for sporadic occurrence of isolates with reduced susceptibility.

Blastomycosis in the mountainous region of northeast Tennessee.

Background: In the United States, cases of human blastomycosis are largely described in defined geographic areas, with Mississippi reporting the highest prevalence of disease in the southeast region. The infection is uncommonly recognized in mountainous areas, and our previous report of blastomycosis in the southern Appalachian mountains of northeast Tennessee appeared to be an exception to the usual disease distribution.

Methods: Our current retrospective study was undertaken to determine whether blastomycosis has persisted as an endemic fungal infection in our northeast Tennessee geographic area and whether epidemiologic features have changed over a 25-year time period.

Nodular pulmonary histoplasmosis in Cushing's disease: a case report and literature review.

Opportunistic infections are well documented in states of steroid excess. To our knowledge, histoplasmosis has not been previously reported in Cushing's disease, and has rarely been reported in patients with exogenous glucocorticoid use. We report a novel presentation of Histoplasmosis as pulmonary nodules in a patient with Cushing's disease.

Unusual case of pyopneumothorax in Tennessee.

Rupture of a coccidioidal pulmonary cavity with subsequent pyopneumothorax is a rare clinical event, even in areas endemic for coccidioidomycosis. Our encounter with a patient diagnosed with this condition in northeast Tennessee serves notice to clinicians that coccidioidomycosis is indeed a traveling fungal disease, and practitioners must be alert to common and uncommon manifestations of infection associated with this fungus. A literature review pertaining to coccidioidal pyopneumothorax revealed that patients usually present with a recent onset of chest pain.

Corynebacterium striatum: an underappreciated community and nosocomial pathogen.

Corynebacterium striatum (CS) is an underappreciated human pathogen that has been associated with serious infections in both immunocompetent and immunocompromised hosts. CS infections tend to be more frequent in males and major infection sites have included blood stream, lung, and central nervous system. Most are nosocomially acquired and there is a significant association with medical devices ranging from intravascular catheters to central nervous system drainage devices.

A decline in mupirocin resistance in methicillin-resistant Staphylococcus aureus accompanied administrative control of prescriptions.

Susceptibility to mupirocin was assessed in methicillin-resistant Staphylococcus aureus isolates selected from eras corresponding to differences in usage rate and prescription policies at a Veterans Affairs medical center. The eras studied encompassed from the time of introduction of the drug to its widespread use, through recommended judicious use, and finally to subsequent stringent administrative control. Prescriptions declined from 3.

Infectious causes of adrenal insufficiency.

More than 150 years ago, Thomas Addison first described the clinical features and pathogenesis of adrenal insufficiency. At that time, tuberculosis was the most common cause of this disease. The pathway to diagnosis and treatment of Addison's disease has been well described.

Mupirocin-resistant, methicillin-resistant Staphylococcus aureus: does mupirocin remain effective?

Objective: To determine the efficacy of mupirocin ointment in reducing nasal colonization with mupirocin-susceptible, methicillin-resistant Staphylococcus aureus (MS MRSA) as well as mupirocin-resistant MRSA (MR MRSA).

Design: Prospective evaluation in which patients colonized with MRSA were treated twice daily with 2% topical mupirocin ointment for 5 days.

Setting: James H.
