Among 82 patients who underwent liposuction performed by a single practitioner in a 6-month period, 34 (41%) developed cutaneous abscesses. An organism identified as Mycobacterium chelonae by polymerase chain reaction restriction-enzyme analysis was recovered from cultures of samples from 12 of those patients. DNA large restriction-fragment pattern analysis(More)
BACKGROUND MRSA prevalence in nursing homes often exceeds that in hospitals, but reasons for this are not well understood. We sought to measure MRSA burden in a large number of nursing homes and identify facility characteristics associated with high MRSA burden. METHODS We performed nasal swabs of residents from 26 nursing homes to measure MRSA(More)
Performance of indirect fluorescent antibody (IFA) assays and rapid influenza diagnostic tests (RIDT) during the 2009 H1N1 pandemic was evaluated, along with the relative effects of age and illness severity on test accuracy. Clinicians and laboratories submitted specimens on patients with respiratory illness to public health from April to mid October 2009(More)
BACKGROUND Observational studies on pediatric anesthesia neurotoxicity have been unable to distinguish long-term effects of general anesthesia (GA) from factors associated with the need for surgery. A recent study on elementary school children who had received a single GA during the first year of life demonstrated an association in otherwise healthy(More)
OBJECTIVE To describe demographic and clinical features of invasive group A streptococcal (GAS) infections in children with varicella in Southern California in early 1994. METHODS From hospitals of Los Angeles and Orange Counties, children with invasive GAS infections after varicella between January 1 and April 8, 1994, were identified by hospital(More)
Foodborne transmission is estimated to account for 95% of non-typhoidal Salmonella infections reported in the United States; however, outbreaks of salmonellosis are rarely traced to food handlers. In August 2000, an increase in Salmonella serotype Thompson infection was noted in Southern California; most of the cases reported eating at a restaurant chain(More)
We assessed characteristics associated with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) carriage among residents of 22 nursing homes. Of MRSA-positive swabs, 25% (208/824) were positive for CA-MRSA. Median facility CA-MRSA percentage was 22% (range, 0%-44%). In multivariate models, carriage was associated with age less than 65(More)
BACKGROUND An anesthesiologist was diagnosed as having acute hepatitis C 3 days after providing anesthesia during the thoracotomy of a 64-year-old man (patient A). Eight weeks later, patient A was diagnosed as having acute hepatitis C. METHODS We performed tests for antibody to hepatitis C virus (HCV) on serum samples from the thoracotomy surgical team(More)
OBJECTIVE To identify characteristic clinical manifestations and potential risk factors for invasive group A streptococcal (GAS) disease in children with varicella. DESIGN AND PARTICIPANTS A case-control study was conducted in Los Angeles and Orange Counties, CA. Cases were children with varicella who developed invasive GAS disease between January 1 and(More)
