Thirty patients undergoing long-term home-based peritoneal dialysis were monitored for 13 months for carriage of Staphylococcus aureus in the nares and for the development of infectious complications. The patients could be divided into three groups with regard to S aureus carriage: chronic, intermittent, and noncarriers. Twenty-five episodes of peritonitis(More)
We reviewed 21 cases of eosinophilia-myalgia syndrome to describe the range of clinical findings in these patients. Most patients were women (20 [95%]) and middle-aged (mean, 46 years) and had taken the food supplement L-tryptophan (95%). All cases involved eosinophilia (eosinophil count, greater than or equal to 2.0 x 10(9)/L) and incapacitating myalgias.(More)
Unusual, primarily pulmonary, manifestations of hantaviral illness occurring in the southwestern United States raised the possibility of person-to-person transmission of a recently recognized hantavirus, Sin Nombre virus. To determine whether such transmission had occurred among health care workers (HCWs) exposed to patients with confirmed hantavirus(More)

Laboratory testing by the National Public Health Laboratory in Tamaulipas, Mexico, showed that the lotion(More)
When amikacin first became available its use was restricted to prevent the emergence of resistant strains of gram-negative bacilli to this new agent. Gentamicin was the aminoglycoside most widely used at this time, and the incidence of gentamicin-resistant bacteria was 14%, while only 2.4% were resistant to amikacin. For a period of 15 months gentamicin use(More)
New Mexico leads the nation in poisoning mortality, which has increased during the 1990s in New Mexico and the United States. Most of this increase has been due to unintentional deaths from illicit drug overdoses. Medical examiner and/or vital statistics data have been used to track poisoning deaths. In this study, the authors linked medical examiner and(More)
On Oct 30, 1989, the New Mexico Health and Environment Department learned of 3 patients with eosinophilia and severe myalgia who had been taking L-tryptophan. Further review of these and similar cases led to the initial recognition of the eosinophilia-myalgia syndrome (EMS) epidemic. To elucidate the apparent association between L-tryptophan-containing(More)

In May 1993, an outbreak of hantavirus pulmonary syndrome (HPS) in the southwestern United States was caused by the previously unrecognized Sin Nombre virus (SNV). Most HPS patients had an influenza-like prodrome, followed by rapid onset of pulmonary edema (fatality rate, 52%). To define the magnitude of the outbreak, patients with milder illnesses who(More)
To determine the prevalence of firearm ownership and storage practices in New Mexico, we did a random-digit-dialing survey of New Mexico residents in October 1991. Of 200 households surveyed, 79 (40%) had 1 or more firearms in the home. Rural households were more likely than urban households to have firearms (44% versus 30%), and households with annual(More)
