Increasing mortality in intravenous (IV) drug users not reported to surveillance as acquired immunodeficiency syndrome (AIDS) has occurred in New York City coincident with the AIDS epidemic. From 1981 to 1986, narcotics-related deaths increased on average 32% per year from 492 in 1981 to 1996 in 1986. This increase included deaths from AIDS increasing from(More)
A model has been developed in which rhinoviral colds can be predictably transmitted by experimentally infected donors to susceptible recipients in a continuously monitored and controlled environment under simulated natural conditions. Rates of transmission correlated closely (r = .926, P less than .01) with donor-hours of exposure. This model can be used to(More)
The adequacy of treatment for syphilis has routinely been evaluated by the serological response, i.e. the rapid plasma reagin test (RPR). Since the description of AIDS and HIV aspects of both the natural history of syphilis and the response of Treponema pallidum to treatment have come under increased scrutiny. With concurrent epidemics of HIV and syphilis(More)
Twenty-two young children, maintained on a diet that excluded certain foods, were challenged intermittently with a blend of seven artificial colors in a double-blind trial. Parents' observations provided the criteria of response. One child that responded mildly to the challenge and one that responded dramatically were detected. The latter, a 34-month-old(More)
Patients who attended a sexually transmitted disease clinic in New York City in 1987 were offered enrollment in a nonblinded study to estimate human immunodeficiency virus type 1 (HIV-1) seroprevalence in adults with multiple sexual partners and to determine risk factors associated with HIV-1 infection. In addition, a blinded serosurvey of a representative(More)
From 1987 to 1989, an epidemic of congenital syphilis was observed in New York City. A case-control study was done to assess the association between various maternal risk factors and congenital syphilis. Independent of the effect of other factors, the odds of being exposed to cocaine were 3.9 times greater among cases than controls (95% confidence interval,(More)
In October and November 1987, eight cases of type E botulism occurred in New York City and Israel. All eight patients had eaten uneviscerated, salted, air-dried whitefish known as kapchunka. Clostridium botulinum was isolated from samples of fish, and trypsinized portions of kapchunka contained type E toxin despite levels of salt that were far in excess of(More)
