ABSTRACT
To date there is only one single-center study that has exclusively reported characteristics, location, and outcomes of spontaneous intracerebral hemorrhages (ICH) among cocaine users. We aimed to describe the radiological location and characteristics along with clinical outcomes of spontaneous ICH in a similar population. We conducted a retrospective chart review of consecutive patients admitted to a tertiary care hospital, with a spontaneous ICH, who had a urine drug screen performed within 48 hours of admission. Exposure to cocaine was defined by a positive urine drug screen within 48 hours of hospital admission. Demographics, radiographic features of ICH, and short-term clinical outcomes of patients with a positive urine drug screen were analyzed and compared with the cocaine negative group. Among the 102 patients analyzed, 20 (19.6%) had documented exposure to cocaine. There was a predominance of males in both groups with significantly more Blacks in the cocaine positive group (P = 0.0246). A statistically significant number of patients with cocaine use had ICH in a subcortical location (P = 0.0224) when compared to cocaine negative patients. There was no difference in GCS, ICH volume, intraventricular extension, ICU days, hospital days, hospital cost, mortality, and ICH score. ICH in cocaine use is more frequently seen in the subcortical location.
ABSTRACT
We report the first case in the English language literature, to our knowledge, of native valve endocarditis due to Legionella pneumophila. The patient had no prior history of cardiothoracic intervention or congenital valvular process. A transesophageal echocardiogram showed a vegetation on the aortic valve. Blood culture and bronchoalveolar lavage returned positive for L. pneumophila. The patient was treated with levofloxacin for 6 weeks total after a second set of blood cultures were negative. The patient survived a complicated hospital course and was discharged to a rehabilitation facility.

Bacteremia in hemodialysis patients with cuffed tunneled catheters is a significant cause of morbidity and mortality. Native arteriovenous fistulas or vascular prostheses are preferred forms of vascular access, but their creation may not always be possible. Catheter-related bacteremia is due primarily to Gram-positive organisms, but Gram-negative infections are of increasing importance. Bacteremia in patients with catheters results from luminal or extraluminal contamination and may be perpetuated by infected fibrin sheaths associated with the catheter. Bacteremic patients require antibiotic therapy and catheter removal. Guide wire catheter exchange is appropriate in stable patients, but catheter removal and later reinsertion of a new catheter is indicated for tunnel infection or frank sepsis. Late diagnosis or ineffective therapy predisposes to vascular and extravascular infectious complications. Catheter-related bacteremia may be minimized with appropriate sterile technique at insertion, meticulous exit site care, and antibiotic lock solutions. Early recognition and treatment minimize morbidity and mortality, but the optimal solution remains the placement of permanent access.
