BACKGROUND The frequency of the hemolytic uremic syndrome, characterized by microangiopathic hemolytic anemia, thrombocytopenia, and renal failure, is increasing. Although Escherichia coli serotype O157:H7 has been implicated as a causative agent, more information is needed about the basic epidemiology and clinical aspects of this syndrome. METHODS We(More)
BACKGROUND Leukemia is the most common childhood cancer. With the exception of Down syndrome, prenatal radiation exposure, and higher birth weight, particularly for acute lymphoid leukemia (ALL), few risk factors have been firmly established. Translocations present in neonatal blood spots and the young age peak of diagnosis suggest that early-life factors(More)
OBJECTIVE Escherichia coli O157:H7 infection can cause hemorrhagic colitis and hemolytic uremic syndrome. Since 1988 the Minnesota Department of Health has carried out surveillance for this infection. To assess the occurrence of person-to-person transmission within day-care facilities, we investigated facilities where an infected child attended after onset(More)
An outbreak of Salmonella enteritidis infection occurred in patrons and employees of a fast-food restaurant. Transmission took place over a 9-day period. A single employee (employee A) was identified who had onset of gastrointestinal illness 1 day before the first reported patron exposures and had S. enteritidis isolated from stool. A case-control study of(More)
OBJECTIVES The purpose of this study was to estimate cancer incidence for American Indians in Minnesota. METHODS Indian Health Service enrollment data were linked to the Minnesota tumor registry to identify cancers among American Indians in Minnesota. Incidence rates for the 5 most common cancers in this population, estimated after the linkage, were(More)
Wilms tumor (WT) is a childhood kidney cancer with the highest rate of occurrence before the age of 2. Since it is rare, previous research has been limited and few risk factors have been established. We used a case-cohort design to examine the influence of birth characteristics on occurrence of WT in Minnesota. A total of 2,188 cases of cancer diagnosed in(More)
Neuroblastoma (NB), a tumor of the sympathetic nervous system, is the most common infant malignancy. The etiology of NB is largely unknown. We explored the association between birth record variables and subsequent NB development in a population-based case-cohort study in Minnesota by linking the birth and cancer registries. NB cases included 155 children(More)
We investigated an outbreak of erythromycin-resistant Staphylococcus aureus conjunctivitis in a hospital newborn nursery that used erythromycin eye ointment to prevent ophthalmia neonatorum. Cases occurred in 2 clusters; 20 (14%) of 146 infants in the nursery developed conjunctivitis from July through October, 1987; and 5 (7%) of 69 infants in the nursery(More)
BACKGROUND Little is known about the causes of adult leukemia. A few small studies have reported a reduced risk associated with regular use of nonsteroidal anti-inflammatory drugs (NSAID). METHODS In a population-based case-control study, we evaluated analgesic use among 670 newly diagnosed myeloid leukemia cases [including 420 acute myeloid leukemias(More)
